Definitions
- the present invention relates generally to the field of bottled water dispensers and coffee brewing devices and, more particularly, to combination devices that include bottled water dispensing features and coffee brewing devices.
- a bottom-loading bottled water dispenser which includes an exterior cabinet; an interior space that is configured to house a water bottle within the bottom half of the dispenser; a cold water tank and means for dispensing cold water from such tank; a first hot water tank and means for dispensing water from such tank; and a second hot water tank that is configured to deliver hot water to a coffee making device (with the second hot water tank being configured to receive water from the first hot water tank).
- the water dispenser further includes one or more flow sensors, which monitor the flow of water into, and volumes of water contained within, the cold and hot water tanks described herein.
- the invention provides that the coffee making device is integrated into the water dispenser and, preferably, is a single-serve coffee making device.
- the second hot water tank will be configured to be smaller in size (based on its volume), relative to the first hot water tank.
- the water dispenser will include a hot water pump, which causes hot water to travel from the first hot water tank to the second hot water tank, to back-fill water that leaves the second hot water tank as coffee is made by a user.
- the invention provides that the bottled water dispenser includes a single hot water tank, which is configured to hold water that a user may dispense as desired—and is further configured to supply hot water to the coffee making device.
- the water that will eventually be used to make coffee may be held at a sufficiently high temperature, e.g., about 92-96 degrees Celsius, within the second hot water tank.
- the invention provides that replacement water that enters the second hot water tank, from the first hot water tank, may quickly be heated to the desirable coffee-making temperature, e.g., about 92-96 degrees Celsius, since the starting temperature will already be elevated from being held in the first hot water tank.
- This design also reduces the “waiting time” that is often associated with prior art coffee makers, since the water in the second hot tank is held at a temperature that may be effectively and immediately used to produce coffee.
- the hot water tank will be configured to receive water from the cold tank, and then quickly heat the water to a temperature that is suitable for use in producing a coffee beverage as described herein.

- bottom loading water dispensers are provided 10 .
- the water dispensers generally comprise a cabinet having an exterior portion 12 and an interior portion 14 , with the interior portion 14 including a top half 16 and a bottom half 18 .
- the bottom loading water dispensers include a water bottle 20 that is disposed in the bottom half 18 of the interior portion 14 of the cabinet (in an upright position).
- the water dispensers will include a set of (hot 22 A/cold 22 B) water dispensing actuator buttons 22 , which may be operated to dispense both cold water and hot water, as desired (i.e., to cause water to be extracted from the water bottle 20 , travel through a set of interior tubes, through a cold tank (and, for hot water, through a hot tank), and exit through a cold or hot water tap).
- the water dispenser will include a fully integrated coffee making device 24 , which will preferably be a single-serve coffee making device.
- the invention provides that the coffee making device 24 will utilize water that is originally housed within the water bottle 20 , and transferred to a set of two hot water tanks (described below), prior to being used to produce coffee by the coffee making device 24 .
- the water that is originally housed within the water bottle 20 may be transferred to a single hot water tank ( FIGS. 6-8 ), prior to being used to produce coffee by the coffee making device 24 .
- the water dispensers of the present invention comprise a first hot tank 26 , a second hot tank 28 (positioned above the first hot tank 26 ), a cold tank 30 , a flow meter 36 (configured to monitor the volume of water that flows from the first hot tank 26 to the second hot tank 28 ), a one-way valve 34 (configured to allow water to leave the second hot tank 28 and enter the coffee making device 24 and further designed to prevent brewed coffee from leaving the coffee making device 24 and flowing back into the hot tank 28 due to the pressure created in the coffee making device 24 ), a first pump 32 (configured to cause water to move from the first hot tank 26 to the second hot tank 28 ), an optional solenoid valve 38 (which is normally closed and in-line between the first hot tank 26 to the second hot tank 28 ), a compressor 40 (for the cooling system of the cold tank 30 ), a second pump 42 (configured to cause water to move from the water bottle 20 to the cold tank 30 ), a water bottle 20 , a water bottle 20 , a water bottle 20 ,
- the invention provides that the coffee making device 24 employs the use of the dual hot tank design described herein, in order to ensure that optimal water temperatures can be quickly achieved when brewing coffee with the device. More particularly, the invention provides that water in the water bottle 20 will enter the cold tank 30 of the water dispenser, via a force provided by the second pump 42 . The water that is held within the cold tank 30 may then travel, via hydrostatic forces and a cold water outlet, into the first hot tank 26 . In the first hot tank 26 , the water is heated, e.g., via a set of electric heating coils 64 (FIG. 9 E/ 9 F), to a final temperature that ranges between 75 and 96 degrees Celsius, and preferably between 85 and 96 degrees Celsius.
- a set of electric heating coils 64 FIG. 9 E/ 9 F
- the invention provides that the heating coils 64 may reside within, or outside of and directly adjacent to, the hot tanks described herein.
- the steam that is created within the first hot tank 26 will be allowed to re-circulate and travel back to the cold tank 30 via one or more outlet (vapor) tubes 60 ( FIG. 5 ).
- the invention provides that the first hot tank 26 is operably connected with a hot water outlet 54 , which may be used to dispense hot water from the dispenser (by a user operating the hot water actuator button 22 A to cause water to flow from the hot water tap), e.g., if a user wants to access hot water to make, for example, a hot tea or hot chocolate beverage.
- the hot water that is contained within the first hot water tank 26 may also flow into the second hot water tank 28 , which supplies water to the coffee making device 24 , via an optional solenoid (or one-way) valve 38 , a first flow sensor 36 , and a first pump 32 .
- the optional solenoid (or one-way) valve 38 may be closed, unless water is traveling from the first hot water tank 26 to the second hot water tank 28 .
- the water is heated, e.g., via a set of electric heating coils, to a final temperature that preferably ranges between 92 and 96 degrees Celsius.
- the invention provides that the steam and excess hot water (created due to expansion from the water heating process) that is generated within the second hot water tank 28 may be diverted back to the cold tank 30 through the solenoid valve 9 .
- the one-way solenoid valve 9 is typically open (unless water is being diverted to the coffee making device 24 ) and is connected to an outlet (vapor) tube 62 .
- the invention provides that the solenoid valve 9 will preferably be open and allow steam that is generated within the second hot water tank 28 to be diverted back to the cold tank 30 at all times (through the outlet tube 62 and solenoid valve 9 ), unless water is being transferred from the second hot water tank 28 to the coffee making device 24 via tube 63 , which includes a one-way spring-loaded valve 34 .
- the one-way spring-loaded valve 34 is normally closed due to a light force provided by the spring, such that steam and vapors do not drip into the coffee making device 24 , but will be caused to open by water pressure, when water is transferred from the second hot water tank 28 to the coffee making device 24 .
- the invention provides that the controls of the water dispenser ( FIG. 3 ) may be operated to cause hot water to travel from the second hot water tank 28 and into the coffee making device 24 .
- the hot water makes contact with an appropriate volume of coffee grinds, which melts the coffee grinds to create the desired coffee beverage.
- the coffee grinds may reside in a plastic, disposable cartridge, whereby the coffee making device 24 is configured to make a hot water entry aperture and hot water exit aperture in the cartridge (which may be comprised of tin foil, plastics, or combinations thereof), such that the hot water may enter the cartridge, contact the coffee grinds, dissolve the coffee grinds to produce a coffee beverage, and then be expelled from the cartridge through the exit aperture, such that the coffee beverage may be dispensed via a dedicated coffee outlet 56 (and coffee tap).
- a hot water entry aperture and hot water exit aperture in the cartridge which may be comprised of tin foil, plastics, or combinations thereof
- the coffee making device 24 may comprise two hollow spikes, which are configured to create the hot water entry and hot water exit apertures.
- a first spike 124 ( FIGS. 2 and 14 ) will comprise a blunt end (located within a lid portion of the dispenser), which will be configured to pierce the top of the coffee cartridge to create the hot water entry aperture.
- the second spike 122 ( FIGS. 1 and 13 ) will be located in an area that is configured to receive the coffee cartridge, and will be configured to exhibit a sharp end, and to be capable of piercing the bottom of the cartridge to create the exit aperture.
- the invention provides that such spikes are hollow, with the first spike 124 being coupled to a line that delivers water to the coffee making device 24 (from a hot tank), and the second spike 122 coupled to a line that removes coffee beverage from coffee making device 24 , and allows such coffee beverage to exit through the coffee outlet 56 (and coffee tap).
- the spikes 122 , 124 will preferably comprise a threaded end (or a roughed end), which is configured to help bond the spikes 122 , 124 to the injected plastic housings into which the spikes 122 , 124 are positioned and attached.
- the coffee making device 24 will preferably comprise a self-locking lid, which may be opened (and closed) at the top side of the cabinet of the water dispenser, such that the disposable cartridges (which contain the ground coffee ingredients) may be inserted into and removed from the coffee making device 24 as needed.
- the first spike 124 (which exhibits a blunt end) will be recessed within (or, alternatively, flush with) a surrounding “safety” wall 125 ( FIGS. 1 , 2 , and 7 ).
- the invention provides that the surrounding wall 125 will prevent a user from inadvertently making contact with the spike 125 and potentially injuring his/her hand.
- the blunt-ended shape of the spike 124 further mitigates the chance for user injury.
- the invention provides that a user may instruct the water dispenser to produce a serving of coffee, through a main control board 58 located on the exterior cabinet of the water dispenser (e.g., on the top side of the exterior cabinet).
- the main control board 58 will issue a signal to activate a control solenoid valve 38 , whereupon hot water that is contained within the first hot water tank 26 travels into the second hot water tank 28 (with the force being provided by the pump 32 ), with the first flow sensor 36 controlling and monitoring water capacity of the second hot water tank 28 .
- the control solenoid valve 38 and pump 32 stop working.
- the second hot tank 28 remains full with water, which is heated within the second hot water tank 28 to a pre-defined temperature, e.g., 96-degrees Celsius, at which point the second hot water tank 28 operates to maintain the water at such temperature.
- a pre-defined temperature e.g., 96-degrees Celsius
- This process minimizes the time that is required to produce a coffee beverage (since the water in the second hot water tank 28 is at the necessary brewing temperature).
- this process mitigates the cooling effect of the cold water that is provided to the hot tanks from the cold tank 30 , since the cold water is first transferred to the first hot tank 26 and heated, before it is later transferred to the second hot tank 28 .
- the invention provides that a user of the water dispenser may operate the main control board 58 to instruct the dispenser to produce a single-serving of coffee and, in so doing, may specify the volume of the serving among two or more options (e.g., a “big cup” or “small cup”).
- the control solenoid valve 38 and pump 32 are activated, whereupon a defined amount of hot water that is contained within the first hot water tank 26 is forced into the second hot water tank 28 .
- a proportionate amount of hot water that is contained in the second hot water tank 28 is forced (under pressure) into the coffee making device 24 , where such water makes contact with coffee grinds as described above, which produces the desired coffee beverage that may be dispensed via a dedicated coffee outlet 56 .
- the invention provides that the first flow sensor 36 controls water capacity in the second hot tank 28 , such that upon a user selecting the “big cup” or “small cup” option, the flow sensor 36 will issue a signal when the flow of water has reached the pre-defined water flow that is correlated with the selected “big cup” or “small cup” setting. Upon the flow sensor 36 issuing such a signal, the main control board 58 issues an instruction to deactivate the control solenoid valve 38 and pump 32 and to stop pumping water.
- a set of electrodes may be used to monitor and determine when the water levels in the cold tank 30 and hot tanks 26 , 28 have reached full capacity. For example, when sufficient water is present in such tanks, a pair of electrodes (near the top of such tanks) will be immersed in water, such that an electrical current is allowed to flow between such electrodes. The electrical flow is communicated to the control board 58 , which issues a deactivation signal to the pumps. For example, when an electrical signal is detected by electrodes 72 ( FIG.
- the control board 58 may instruct the pump 42 not to operate; whereas, if an electrical signal is not detected by electrodes 72 in the cold tank 30 (and the water line resides below such electrodes), the control board 58 may instruct the pump 42 to activate and transfer water from the water bottle 20 to the cold tank 30 , until such time that an electrical signal is detected by electrodes 72 .
- the control board 58 may instruct the pump 32 not to operate; whereas, if an electrical signal is not detected by electrodes in the second hot tank 28 (and the water line resides below such electrodes), the control board 58 may instruct the pump 32 to activate and transfer water from the first hot tank 26 to the second hot tank 28 .
- This flow of water may further cause water to be hydrostatically transferred (back-filled) from the cold tank 30 and into the first hot tank 26 , since the cold tank 30 will be positioned higher than the first hot tank 26 (with the water that is extracted from the cold tank 30 being replaced with water that is extracted from the water bottle 20 ).
- the vent tube 60 permits steam and air to leave the hot tank 26 , which also facilitates the hydrostatic transfer of water from the cold tank 30 into the first hot tank 26 .
- the current water volumes of the cold tank 30 and hot tanks 26 , 28 described herein may be monitored and calculated via in-line flow sensors.
- the cold tank 30 may further comprise a buoyant cold water baffle 70 , which rises and falls along with the water level within the cold tank 30 .
- a mechanical float valve 128 may, optionally, be employed to serve as a back-up water volume control for the cold water tank 30 .
- FIG. 15 provides an illustration of the second hot tank 28 described herein.
- the second hot tank 28 may hold about 600 mL of water—and may be provided with up to about 1500 watts to heat the water contained therein.
- the second hot tank 28 may have a lower half 138 and an upper half 135 , and comprise an intake water pipe 139 (which receives water from the first hot tank 26 ); an external heating element 141 ; a safety cover 140 ; a thermostat well 136 for an electronic temperature sensor/thermostat; an O-ring seal 133 ; a clamp 137 ; electronic sensors 134 for monitoring whether the hot tank 28 is full (as described herein); a vent/steam return line 131 (configured to return air and steam back to the cold tank 30 ); and a water-exit port 132 that is used to deliver water to the coffee making device 24 .
- the hot tank 28 may alternatively be welded together without a clamp 137 and, furthermore, may include a mechanical thermostat (instead of an electronic thermostat).
- the hot tank 28 may comprise an internal heating element (in replacement of or in addition to the external heating element 141 ).
- the invention provides that the cold tank 30 will preferably exhibit an approximately rectangular shape, i.e., the perimeter of the cold tank 30 exhibits a substantially rectangular perimeter and cross-section (unlike most cold tanks used in prior art water dispensers, which are typically cylindrical in shape). This is also shown in FIG. 16 .
- the invention provides that the approximately rectangular shaped cold tank 30 saves needed space within the interior 14 of the dispenser.
- the invention further encompasses the use of other space-saving and non-cylindrically, irregularly-shaped cold tanks 30 .
- the cold tank 30 will preferably comprise an internal cooling evaporator 74 (instead of an externally placed evaporator as in many prior art cooling tanks).
- the invention provides that the internal cooling evaporator 74 will house the coolants that are used to chill the water that is contained within the cold tank 30 . More particularly, the evaporator 74 will be comprised of stainless steel and copper or aluminum laminated material, with the exterior surface of the evaporator 74 (which contacts the water in the cold tank 30 ) being comprised of stainless steel. Still further, the invention provides that the cold tank 30 will preferably be comprised of a food grade material, such as polypropylene material.
- the invention provides that the water dispensers of the present invention may comprise only a single hot tank 80 .
- the water dispensers in such embodiments will be similar to those described above, with the exception that the dispensers will include one hot tank 80 instead of two separate tanks 26 , 28 ( FIGS. 1 and 5 ).
- the single hot tank 80 will receive water from the cold tank 30 .
- the water line between the cold tank 30 and hot tank 80 will include a flow meter 43 A and water pump 43 B.
- the invention provides that when cold water is pumped from the cold tank 30 into the hot tank 80 , the one-way valve 43 will prevent such water from back-flowing into the cold tank 30 .
- the one-way valve 43 will close upon receiving a signal that water is being transferred from the hot tank 80 to the coffee making device 24 (in certain alternative embodiments, the one-way valve 43 may be a solenoid valve).
- the water line between the hot tank 80 and the coffee making device 24 may also include a one-way spring-loaded valve 33 , which may exist in a “closed” position, unless a user instructs the dispenser to produce a cup of coffee as described herein, in which case the water pressure (provided by the water pump 43 B) will cause the one-way spring-loaded valve 33 to open and allow a defined volume of water to be transferred from the hot tank 80 and into the coffee making device 24 (although a one-way spring-loaded valve 33 may be employed as described, the invention provides that a solenoid valve may also be used).
- a one-way spring-loaded valve 33 may exist in a “closed” position, unless a user instructs the dispenser to produce a cup of coffee as described herein, in which case the water pressure (provided by the water pump 43 B) will cause the one-way spring-loaded valve 33 to open and allow a defined volume of water to be transferred from the hot tank 80 and into the coffee making device 24 (although a one-way spring-loaded valve
- the water dispenser will include a pump 43 B, which is configured to pump water from the cold tank 30 and into the hot tank 80 , with a flow meter 43 A located in such water line between the cold tank 30 and hot tank 80 , with the flow meter being configured to monitor and restrict the volume of water that is transferred from the cold tank 30 and into the hot tank 80 , to the volume of water that corresponds to, and is needed to produce, the desired volume of coffee beverage.
- a pump 43 B which is configured to pump water from the cold tank 30 and into the hot tank 80
- a flow meter 43 A located in such water line between the cold tank 30 and hot tank 80
- the flow meter being configured to monitor and restrict the volume of water that is transferred from the cold tank 30 and into the hot tank 80 , to the volume of water that corresponds to, and is needed to produce, the desired volume of coffee beverage.
- the hot tank 80 may comprise one or more internally mounted thermostats 90 that are configured to monitor the temperature of the water contained therein, and communicate such information to the control board 58 (in certain alternative embodiments, the thermostats 90 may be externally mounted).
- the water is heated within a reasonable amount of time, e.g., via a set of electric heating coils 64 , to a final temperature that preferably ranges between 92 and 96 degrees Celsius.
- the invention provides that the hot tank 80 may comprise a baffle 92 , which separates the interior portion of the hot tank into two separate chambers 94 , 96 .
- the baffle 92 will be configured to allow water to travel from one chamber 96 to another 94 , albeit slowly and gradually.
- the baffle 92 is configured to be located between (1) the side that is closest to the heating coils 64 and (2) the side that comprises the cold water intake area (i.e., the port 102 through which water enters the hot tank 80 from the cold tank 30 ).
- the baffle 92 serves as a type of barrier between the recently injected cold water, and existing hot water, and allows the two chambers of water to gradually be mixed and heated to equilibrium.
- the baffle 92 is configured to minimize the mixing of hot/cold water, while the injected cold water is displacing the hot water that is being transferred to the coffee making device 24 .
- the baffle 92 may exhibit a concave shape, which exhibits a perimeter that is configured to reside adjacent to the interior surface of the hot tank 80 (and may include a set of tabs 106 that are configured to mechanically position and hold the baffle 92 within the hot tank 80 ).

Description
- The present invention relates generally to the field of bottled water dispensers and coffee brewing devices and, more particularly, to combination devices that include bottled water dispensing features and coffee brewing devices.
- The demand for clean and healthy drinking water is increasing dramatically, which is being driven by the rapid growth in population and standards of living across the globe. This demand has translated into a continuing need for safe, clean, and easy to use water dispensers, including for both hot and cold water. In addition, both residential homes and commercial offices will typically have at least one coffee brewing device. Indeed, coffee is among the most frequently-consumed beverages in the world. Since bottled water dispensers often include a source of clean and consumable drinking water, it would be advantageous to combine and integrate the features and functionalities of bottled water dispensers, including for both hot and cold water, and coffee brewing devices (and, particularly, single-serve coffee brewing devices). Furthermore, it would be desirable to provide a product, which combines hot/cold water dispensing features and coffee brewing devices, and is able to produce a single-serve coffee beverage quickly and with consistent quality.
- As the following will demonstrate, many of the foregoing needs are addressed by the present invention.
- According to certain aspects of the invention, a bottom-loading bottled water dispenser is provided, which includes an exterior cabinet; an interior space that is configured to house a water bottle within the bottom half of the dispenser; a cold water tank and means for dispensing cold water from such tank; a first hot water tank and means for dispensing water from such tank; and a second hot water tank that is configured to deliver hot water to a coffee making device (with the second hot water tank being configured to receive water from the first hot water tank). The water dispenser further includes one or more flow sensors, which monitor the flow of water into, and volumes of water contained within, the cold and hot water tanks described herein. The invention provides that the coffee making device is integrated into the water dispenser and, preferably, is a single-serve coffee making device. In certain embodiments, the second hot water tank will be configured to be smaller in size (based on its volume), relative to the first hot water tank. The water dispenser will include a hot water pump, which causes hot water to travel from the first hot water tank to the second hot water tank, to back-fill water that leaves the second hot water tank as coffee is made by a user. In certain alternative embodiments, the invention provides that the bottled water dispenser includes a single hot water tank, which is configured to hold water that a user may dispense as desired—and is further configured to supply hot water to the coffee making device.
- According to such aspects of the invention, when the water dispenser includes two separate hot tanks, the water that will eventually be used to make coffee may be held at a sufficiently high temperature, e.g., about 92-96 degrees Celsius, within the second hot water tank. The invention provides that replacement water that enters the second hot water tank, from the first hot water tank, may quickly be heated to the desirable coffee-making temperature, e.g., about 92-96 degrees Celsius, since the starting temperature will already be elevated from being held in the first hot water tank. This design also reduces the “waiting time” that is often associated with prior art coffee makers, since the water in the second hot tank is held at a temperature that may be effectively and immediately used to produce coffee. Alternatively, when the water dispenser of the present invention comprises a single hot water tank, the hot water tank will be configured to receive water from the cold tank, and then quickly heat the water to a temperature that is suitable for use in producing a coffee beverage as described herein.

These embodiments are provided by way of explanation only, and thus, should not unduly restrict the scope of the invention. In fact, those of ordinary skill in the art will appreciate upon reading the present specification and viewing the present drawings that the invention teaches many variations and modifications, and that numerous variations of the invention may be employed, used and made without departing from the scope and spirit of the invention.
- Referring now to
FIGS. 1-5 , according to certain preferred embodiments of the present invention, bottom loading water dispensers are provided 10. The water dispensers generally comprise a cabinet having anexterior portion 12 and aninterior portion 14, with theinterior portion 14 including atop half 16 and abottom half 18. The bottom loading water dispensers include awater bottle 20 that is disposed in thebottom half 18 of theinterior portion 14 of the cabinet (in an upright position). The water dispensers will include a set of (hot 22A/cold 22B) waterdispensing actuator buttons 22, which may be operated to dispense both cold water and hot water, as desired (i.e., to cause water to be extracted from thewater bottle 20, travel through a set of interior tubes, through a cold tank (and, for hot water, through a hot tank), and exit through a cold or hot water tap). In addition, the invention provides that the water dispenser will include a fully integratedcoffee making device 24, which will preferably be a single-serve coffee making device. As described further below, the invention provides that thecoffee making device 24 will utilize water that is originally housed within thewater bottle 20, and transferred to a set of two hot water tanks (described below), prior to being used to produce coffee by thecoffee making device 24. In certain alternative embodiments, the water that is originally housed within thewater bottle 20 may be transferred to a single hot water tank (FIGS. 6-8 ), prior to being used to produce coffee by thecoffee making device 24. - More specifically, in certain preferred embodiments shown in
FIGS. 1-5 , the water dispensers of the present invention comprise a firsthot tank 26, a second hot tank 28 (positioned above the first hot tank 26), acold tank 30, a flow meter 36 (configured to monitor the volume of water that flows from the firsthot tank 26 to the second hot tank 28), a one-way valve 34 (configured to allow water to leave the secondhot tank 28 and enter thecoffee making device 24 and further designed to prevent brewed coffee from leaving thecoffee making device 24 and flowing back into thehot tank 28 due to the pressure created in the coffee making device 24), a first pump 32 (configured to cause water to move from the firsthot tank 26 to the second hot tank 28), an optional solenoid valve 38 (which is normally closed and in-line between the firsthot tank 26 to the second hot tank 28), a compressor 40 (for the cooling system of the cold tank 30), a second pump 42 (configured to cause water to move from thewater bottle 20 to the cold tank 30), awater bottle 20, and acoffee making device 24. - According to such embodiments, the invention provides that the
coffee making device 24 employs the use of the dual hot tank design described herein, in order to ensure that optimal water temperatures can be quickly achieved when brewing coffee with the device. More particularly, the invention provides that water in thewater bottle 20 will enter thecold tank 30 of the water dispenser, via a force provided by thesecond pump 42. The water that is held within thecold tank 30 may then travel, via hydrostatic forces and a cold water outlet, into the firsthot tank 26. In the firsthot tank 26, the water is heated, e.g., via a set of electric heating coils 64 (FIG. 9E/9F), to a final temperature that ranges between 75 and 96 degrees Celsius, and preferably between 85 and 96 degrees Celsius. The invention provides that the heating coils 64 may reside within, or outside of and directly adjacent to, the hot tanks described herein. The steam that is created within the firsthot tank 26 will be allowed to re-circulate and travel back to thecold tank 30 via one or more outlet (vapor) tubes 60 (FIG. 5 ). In addition, the invention provides that the firsthot tank 26 is operably connected with ahot water outlet 54, which may be used to dispense hot water from the dispenser (by a user operating the hotwater actuator button 22A to cause water to flow from the hot water tap), e.g., if a user wants to access hot water to make, for example, a hot tea or hot chocolate beverage. - According to such embodiments, the hot water that is contained within the first
hot water tank 26 may also flow into the secondhot water tank 28, which supplies water to thecoffee making device 24, via an optional solenoid (or one-way)valve 38, afirst flow sensor 36, and afirst pump 32. The optional solenoid (or one-way)valve 38 may be closed, unless water is traveling from the firsthot water tank 26 to the secondhot water tank 28. In the secondhot water tank 28, the water is heated, e.g., via a set of electric heating coils, to a final temperature that preferably ranges between 92 and 96 degrees Celsius. - The invention provides that the steam and excess hot water (created due to expansion from the water heating process) that is generated within the second
hot water tank 28 may be diverted back to thecold tank 30 through thesolenoid valve 9. The one-way solenoid valve 9 is typically open (unless water is being diverted to the coffee making device 24) and is connected to an outlet (vapor)tube 62. The invention provides that thesolenoid valve 9 will preferably be open and allow steam that is generated within the secondhot water tank 28 to be diverted back to thecold tank 30 at all times (through theoutlet tube 62 and solenoid valve 9), unless water is being transferred from the secondhot water tank 28 to thecoffee making device 24 viatube 63, which includes a one-way spring-loadedvalve 34. The one-way spring-loadedvalve 34 is normally closed due to a light force provided by the spring, such that steam and vapors do not drip into thecoffee making device 24, but will be caused to open by water pressure, when water is transferred from the secondhot water tank 28 to thecoffee making device 24. - In addition, the invention provides that the controls of the water dispenser (
FIG. 3 ) may be operated to cause hot water to travel from the secondhot water tank 28 and into thecoffee making device 24. Within thecoffee making device 24, the hot water makes contact with an appropriate volume of coffee grinds, which melts the coffee grinds to create the desired coffee beverage. In such embodiments, the coffee grinds may reside in a plastic, disposable cartridge, whereby thecoffee making device 24 is configured to make a hot water entry aperture and hot water exit aperture in the cartridge (which may be comprised of tin foil, plastics, or combinations thereof), such that the hot water may enter the cartridge, contact the coffee grinds, dissolve the coffee grinds to produce a coffee beverage, and then be expelled from the cartridge through the exit aperture, such that the coffee beverage may be dispensed via a dedicated coffee outlet 56 (and coffee tap). - More particularly, the invention provides that the
coffee making device 24 may comprise two hollow spikes, which are configured to create the hot water entry and hot water exit apertures. Preferably, a first spike 124 (FIGS. 2 and 14 ) will comprise a blunt end (located within a lid portion of the dispenser), which will be configured to pierce the top of the coffee cartridge to create the hot water entry aperture. The second spike 122 (FIGS. 1 and 13 ) will be located in an area that is configured to receive the coffee cartridge, and will be configured to exhibit a sharp end, and to be capable of piercing the bottom of the cartridge to create the exit aperture. The invention provides that such spikes are hollow, with thefirst spike 124 being coupled to a line that delivers water to the coffee making device 24 (from a hot tank), and thesecond spike 122 coupled to a line that removes coffee beverage fromcoffee making device 24, and allows such coffee beverage to exit through the coffee outlet 56 (and coffee tap). In addition, thespikes spikes spikes coffee making device 24 will preferably comprise a self-locking lid, which may be opened (and closed) at the top side of the cabinet of the water dispenser, such that the disposable cartridges (which contain the ground coffee ingredients) may be inserted into and removed from thecoffee making device 24 as needed. - According to certain preferred embodiments, the first spike 124 (which exhibits a blunt end) will be recessed within (or, alternatively, flush with) a surrounding “safety” wall 125 (
FIGS. 1 , 2, and 7). The invention provides that the surroundingwall 125 will prevent a user from inadvertently making contact with thespike 125 and potentially injuring his/her hand. In addition to the safety feature provided by thewall 125, the blunt-ended shape of thespike 124 further mitigates the chance for user injury. - More particularly, the invention provides that a user may instruct the water dispenser to produce a serving of coffee, through a main control board 58 located on the exterior cabinet of the water dispenser (e.g., on the top side of the exterior cabinet). The main control board 58 will issue a signal to activate a
control solenoid valve 38, whereupon hot water that is contained within the firsthot water tank 26 travels into the second hot water tank 28 (with the force being provided by the pump 32), with thefirst flow sensor 36 controlling and monitoring water capacity of the secondhot water tank 28. When the secondhot water tank 28 reaches full capacity, thecontrol solenoid valve 38 and pump 32 stop working. As water is being pumped from the firsthot tank 26 and into the secondhot tank 28, hot water from the secondhot tank 28 will forced into thecoffee making device 24 viatube 63. The one-way valve 34 will be opened from its normally closed position by the force of the water. After the coffee beverage is produced, the secondhot tank 28 remains full with water, which is heated within the secondhot water tank 28 to a pre-defined temperature, e.g., 96-degrees Celsius, at which point the secondhot water tank 28 operates to maintain the water at such temperature. This process minimizes the time that is required to produce a coffee beverage (since the water in the secondhot water tank 28 is at the necessary brewing temperature). In addition, this process mitigates the cooling effect of the cold water that is provided to the hot tanks from thecold tank 30, since the cold water is first transferred to the firsthot tank 26 and heated, before it is later transferred to the secondhot tank 28. - Still more particularly, the invention provides that a user of the water dispenser may operate the main control board 58 to instruct the dispenser to produce a single-serving of coffee and, in so doing, may specify the volume of the serving among two or more options (e.g., a “big cup” or “small cup”). Upon issuing such instructions via the main control board 58, the
control solenoid valve 38 and pump 32 are activated, whereupon a defined amount of hot water that is contained within the firsthot water tank 26 is forced into the secondhot water tank 28. In turn, a proportionate amount of hot water that is contained in the secondhot water tank 28 is forced (under pressure) into thecoffee making device 24, where such water makes contact with coffee grinds as described above, which produces the desired coffee beverage that may be dispensed via adedicated coffee outlet 56. The invention provides that thefirst flow sensor 36 controls water capacity in the secondhot tank 28, such that upon a user selecting the “big cup” or “small cup” option, theflow sensor 36 will issue a signal when the flow of water has reached the pre-defined water flow that is correlated with the selected “big cup” or “small cup” setting. Upon theflow sensor 36 issuing such a signal, the main control board 58 issues an instruction to deactivate thecontrol solenoid valve 38 and pump 32 and to stop pumping water. - According to certain embodiments of the invention, in addition to the flow sensors described herein (or as an alternative to such flow sensors), a set of electrodes may be used to monitor and determine when the water levels in the
cold tank 30 andhot tanks FIG. 10 ) in thecold tank 30, the control board 58 may instruct thepump 42 not to operate; whereas, if an electrical signal is not detected byelectrodes 72 in the cold tank 30 (and the water line resides below such electrodes), the control board 58 may instruct thepump 42 to activate and transfer water from thewater bottle 20 to thecold tank 30, until such time that an electrical signal is detected byelectrodes 72. - Similarly, for example, when an electrical signal is detected by electrodes in the second
hot tank 28, the control board 58 may instruct thepump 32 not to operate; whereas, if an electrical signal is not detected by electrodes in the second hot tank 28 (and the water line resides below such electrodes), the control board 58 may instruct thepump 32 to activate and transfer water from the firsthot tank 26 to the secondhot tank 28. This flow of water may further cause water to be hydrostatically transferred (back-filled) from thecold tank 30 and into the firsthot tank 26, since thecold tank 30 will be positioned higher than the first hot tank 26 (with the water that is extracted from thecold tank 30 being replaced with water that is extracted from the water bottle 20). Thevent tube 60 permits steam and air to leave thehot tank 26, which also facilitates the hydrostatic transfer of water from thecold tank 30 into the firsthot tank 26. Alternatively, as described herein, the current water volumes of thecold tank 30 andhot tanks FIG. 10 , thecold tank 30 may further comprise a buoyantcold water baffle 70, which rises and falls along with the water level within thecold tank 30. Referring toFIG. 4 , the invention further provides that amechanical float valve 128 may, optionally, be employed to serve as a back-up water volume control for thecold water tank 30. -
FIG. 15 provides an illustration of the secondhot tank 28 described herein. According to certain embodiments, the secondhot tank 28 may hold about 600 mL of water—and may be provided with up to about 1500 watts to heat the water contained therein. Still referring toFIG. 15 , the secondhot tank 28 may have alower half 138 and anupper half 135, and comprise an intake water pipe 139 (which receives water from the first hot tank 26); anexternal heating element 141; asafety cover 140; a thermostat well 136 for an electronic temperature sensor/thermostat; an O-ring seal 133; aclamp 137;electronic sensors 134 for monitoring whether thehot tank 28 is full (as described herein); a vent/steam return line 131 (configured to return air and steam back to the cold tank 30); and a water-exit port 132 that is used to deliver water to thecoffee making device 24. The invention provides that thehot tank 28 may alternatively be welded together without aclamp 137 and, furthermore, may include a mechanical thermostat (instead of an electronic thermostat). In addition, as explained herein in relation to certain alternative embodiments, thehot tank 28 may comprise an internal heating element (in replacement of or in addition to the external heating element 141). - According to still further embodiments, and referring to
FIG. 10 , the invention provides that thecold tank 30 will preferably exhibit an approximately rectangular shape, i.e., the perimeter of thecold tank 30 exhibits a substantially rectangular perimeter and cross-section (unlike most cold tanks used in prior art water dispensers, which are typically cylindrical in shape). This is also shown inFIG. 16 . The invention provides that the approximately rectangular shapedcold tank 30 saves needed space within theinterior 14 of the dispenser. The invention further encompasses the use of other space-saving and non-cylindrically, irregularly-shapedcold tanks 30. Still further, thecold tank 30 will preferably comprise an internal cooling evaporator 74 (instead of an externally placed evaporator as in many prior art cooling tanks). The invention provides that the internal cooling evaporator 74 will house the coolants that are used to chill the water that is contained within thecold tank 30. More particularly, the evaporator 74 will be comprised of stainless steel and copper or aluminum laminated material, with the exterior surface of the evaporator 74 (which contacts the water in the cold tank 30) being comprised of stainless steel. Still further, the invention provides that thecold tank 30 will preferably be comprised of a food grade material, such as polypropylene material. - Referring now to
FIGS. 6-8 , in certain alternative embodiments, the invention provides that the water dispensers of the present invention may comprise only a singlehot tank 80. The water dispensers in such embodiments will be similar to those described above, with the exception that the dispensers will include onehot tank 80 instead of twoseparate tanks 26,28 (FIGS. 1 and 5 ). According to such embodiments, the singlehot tank 80 will receive water from thecold tank 30. The water line between thecold tank 30 andhot tank 80 will include a flow meter 43A andwater pump 43B. The invention provides that when cold water is pumped from thecold tank 30 into thehot tank 80, the one-way valve 43 will prevent such water from back-flowing into thecold tank 30. In addition, the one-way valve 43 will close upon receiving a signal that water is being transferred from thehot tank 80 to the coffee making device 24 (in certain alternative embodiments, the one-way valve 43 may be a solenoid valve). - According to such embodiments, the water line between the
hot tank 80 and thecoffee making device 24 may also include a one-way spring-loadedvalve 33, which may exist in a “closed” position, unless a user instructs the dispenser to produce a cup of coffee as described herein, in which case the water pressure (provided by thewater pump 43B) will cause the one-way spring-loadedvalve 33 to open and allow a defined volume of water to be transferred from thehot tank 80 and into the coffee making device 24 (although a one-way spring-loadedvalve 33 may be employed as described, the invention provides that a solenoid valve may also be used). Still further, as in the other embodiments described herein, the water dispenser will include apump 43B, which is configured to pump water from thecold tank 30 and into thehot tank 80, with a flow meter 43A located in such water line between thecold tank 30 andhot tank 80, with the flow meter being configured to monitor and restrict the volume of water that is transferred from thecold tank 30 and into thehot tank 80, to the volume of water that corresponds to, and is needed to produce, the desired volume of coffee beverage. - Referring to
FIG. 9A-9G , thehot tank 80 may comprise one or more internally mountedthermostats 90 that are configured to monitor the temperature of the water contained therein, and communicate such information to the control board 58 (in certain alternative embodiments, thethermostats 90 may be externally mounted). In thehot tank 80, the water is heated within a reasonable amount of time, e.g., via a set of electric heating coils 64, to a final temperature that preferably ranges between 92 and 96 degrees Celsius. The invention provides that thehot tank 80 may comprise abaffle 92, which separates the interior portion of the hot tank into twoseparate chambers baffle 92 will be configured to allow water to travel from onechamber 96 to another 94, albeit slowly and gradually. Thebaffle 92 is configured to be located between (1) the side that is closest to the heating coils 64 and (2) the side that comprises the cold water intake area (i.e., theport 102 through which water enters thehot tank 80 from the cold tank 30). This way, thebaffle 92 serves as a type of barrier between the recently injected cold water, and existing hot water, and allows the two chambers of water to gradually be mixed and heated to equilibrium. In addition, thebaffle 92 is configured to minimize the mixing of hot/cold water, while the injected cold water is displacing the hot water that is being transferred to thecoffee making device 24. - Referring to
FIG. 9 , thebaffle 92 may exhibit a concave shape, which exhibits a perimeter that is configured to reside adjacent to the interior surface of the hot tank 80 (and may include a set oftabs 106 that are configured to mechanically position and hold thebaffle 92 within the hot tank 80). The concave shape of thebaffle 92 serves to deflect water down, which rises after being heated by the bottom of the hot tank 80 (the bottom of thehot tank 80 is embedded with, connected to, or brazed to a heating element 95/heating coil 64). In addition, the invention provides that thebaffle 92 may comprise one or more apertures 109 through which water may move from onechamber 96 to another 94 of the hot tank 80 (FIG. 9G ). - The invention provides that the
water heating cons 64 may operate under a wattage regulator, which is programmed to use moderate wattage, e.g., 425-500 watts, for heating the water contained in thehot tank 80. The invention further provides that a user may select—through the control board 58—a preheat option. The preheat option may instruct thehot tank 80 to activate a full wattage program (e.g., totaling 1200 watts, and up to 1500 watts), which may be employed to expedite the heating of water contained in thehot tank 80 for the purpose of making a coffee beverage. - Still further, the water dispensers of the present invention may comprise a power-saving “sleep option.” More particularly, the control board 58 may include an interface that allows a user to specify a regular daily period of time during which the dispenser is not often used, referred to herein as the “sleep time” or “down time” (e.g., during the late night hours when most people are sleeping and not using the dispenser). During the defined “sleep time” periods, the preferred temperature(s) of the hot tank(s) described herein may drop, which will thereby save and preserve the amount of energy that is necessary to maintain the water at the “normal” elevated temperatures. For example, in the case of a single
hot tank 80 embodiment, during the “sleep time,” the preferred and maintained temperature of the water may drop to about 60-75 degrees Celsius (and preferably consume a moderate amount of energy). In the event that a user attempts to dispense hot water during the ‘sleep time” (or activates a pre-heat function on the coffee making device 24), a heating boost function may be deployed, whereby the heating cons activate and are provided with additional wattage to quickly heat the water to a preferred range of 92 and 96 degrees Celsius. - In the case of a dual
hot tank hot tank 26 may range between 400-600 watts, and the wattage provided to the secondhot tank 28 may have a connected load up to 1100 watts (so long as the total wattage, between the first and secondhot tanks hot tank 28 may be completely disconnected or, alternatively, provided with a cyclical amount of wattage (e.g., bursts of 4-60 watts every second or fraction thereof) to maintain the temperature of the water contained therein within a defined range—albeit within a range that is the same as, or cooler than, the temperature of the water during normal operational time periods. As mentioned above, in certain alternative embodiments, the heating coils for one or both of the twohot tanks - Referring to the embodiment above, whereby a hot tank may power-down during “sleep time” by receiving cyclical amounts of wattage, the invention provides that the magnitude and frequency of the wattage bursts may be adjusted in real time. For example, if the temperature of the water within the hot tank falls below a defined range, the frequency (and/or magnitude) of the supplied wattage may be increased (to heat the water); if the temperature of the water within the hot tank elevates above the defined range, the frequency (and/or magnitude) of the supplied wattage may be decreased (to allow the water to cool); and if the temperature of the water within the hot tank falls within the defined range, the frequency (and/or magnitude) of the supplied wattage will be maintained.
- As mentioned above, the water dispensers of the present invention include a set of water dispensing
actuator buttons 22. The waterdispensing actuator buttons 22 will preferably include at least one child safety latch in at least one of the buttons (the hotwater actuator button 22A). The child safety latch preferably comprises an element that is configured to be moved in a first direction (on the exterior surface of the actuator button 22), e.g., inward and towards the center of the button, which allows the actuator button to then be pushed downwards to cause hot water to be dispensed. When the child safety latch is released (and the force that moved the element in the first direction is removed), an internal spring will force the element back in a second direction, which prevents the actuator button from being pushed downwards (thereby preventing hot water from being dispensed). - Referring now to
FIG. 11 , according to further embodiments of the present invention, the water dispensers include a front door 67 that includes adrip tray 69. Thedrip tray 69 is preferably built into the front door 67, such that it is located beneath the external taps (which dispense water and coffee), and is integrally formed into the top portion of the front door 67 of the cabinet. This configuration has been found to increase the amount of room that is available to place a glass (or other container) beneath the external taps when receiving dispensed water or coffee, while simultaneously reducing the total height of the water dispenser (which is beneficial for shipping and retail storage purposes). In addition, the dispensers may comprise acoffee cup platform 68, which may be varied in height to accommodate different sized cups (and to preferably position the top of the cup in the proximity of the coffee tap). The invention provides that the cabinet of the water dispensers may be comprised of various materials, such as stainless steel, plastics, or other materials. - Referring now to
FIG. 12 , according to certain preferred embodiments of the present invention, the dispensers further include abottle tray 76 disposed at the bottom of thebottom half 18 of theinterior portion 14 of the cabinet. Thebottle tray 76 is configured to receive the bottom surface of thewater bottle 20 in an upright position. Importantly, thebottle tray 76 is slanted from afront side 78A to abackside 78B of thetray 76. That is, when facing the front of the water dispenser, i.e., the side on which theactuator buttons 22 are located, thebottle tray 76 is higher at thefront side 78A thereof than thebackside 78B of thetray 76. The slope of the slant will preferably range from 5-30 degrees. This configuration facilitates the insertion of afull water bottle 20 into thebottom half 18 of theinterior portion 14 of the cabinet (in an upright position). The invention provides that thebottle tray 76 may also comprise a recessedarea 82 that is configured to receive a bottom surface of thewater bottle 20. Thebottle tray 76 may comprise aperimeter wall 84, which is configured to prevent thewater bottle 20 from falling out of the cabinet, particularly when pressure may be injected into the water bottle to extract water therefrom. According to such embodiments, thebottle tray 76 may comprise alip 86 that is configured to assist a user with inserting thewater bottle 20 onto thebottle tray 76. - The many aspects and benefits of the invention are apparent from the detailed description, and thus, it is intended for the following claims to cover all such aspects and benefits of the invention, which fall within the scope and spirit of the invention. In addition, because numerous modifications and variations will be obvious and readily occur to those skilled in the art, the claims should not be construed to limit the invention to the exact construction and operation illustrated and described herein. Accordingly, all suitable modifications and equivalents should be understood to fall within the scope of the invention as claimed herein.
