3319~7 DISHWASHING APPARATUS INCLUDING A
FLIP-TOP SOLID DETERGENT DISPENSER
This application is a divisional application of Application Serial No. 565,587 filed 29 April, 1988.

Backqround of the Invention 1. Field of the Invention This invention relates generally to a dishwasher apparatus, more particularly to a dis-hwasher apparatus having only one incoming water line and using a pump to circulate water against various additives such as detergent sources and rinse aid sources. Such invention is also designed to save on additives and hot water. Also, the dishwashing apparatus is designed in such a way as to save on space and installation costs.
The invention also relates to a flip-top detergent dispenser, designed to hold a particularly shaped detergent container. Said flip-top detergent dispenser is designed in such a manner as to facilitate the safe and convenient insertion and removal of the particularly shaped detergent container into the flip-top detergent dispenser. Said ~lip~
top detergent dispenser is designed only to operate with the particularly shaped detergent container, thus preventing the use of an incompatible and unsa~e product in said dishwasher apparatus.

2. _ Discussion of Related Technolo~y Dishwasking apparatuses ,which, make use of solid dishwashing additives such as a solid~detergent Isource and a solid rinse aid source are known in the art. To use such a dishwashing apparatus, water is directed onto each of the , solid additives in order to form additive solutions which can be circulated throughout the machine. SUCh dishwashing apparatuses o~ the prior art have typically utilized three separate outside wzterlines. One waterline served to fill , the mackine with clean hot water. The other two waterlines directed water through two separate product nozzles onto a ~:; , ' ;
~

,v^
`

3 1 9 ~ 7 ~ ~

solid detergent source and a solid rinse aid source respectively, in order to form a detergent solution and a rinse aid solution.
Due to fluctuations in water pressure in various areas -~
5 of the country, pressure regulating valves and pressure ;
gauges, in addition to vacuum breakers, had to be used on each of the waterlines directing water through product nozzles onto the solid detergent source and rinse aid source -~
in order that solutions of appropriate concentrations be formed. Thus, in hooking up such a commercial dishwashing apparatus, three outside waterlines had to be used, necessitating the use of three vacuum breakers, three pressure regulating valves, and three pressure gauges.
Also in the dishwashing apparatuses of the prior art, lS the solid rinse aid and solid detergent source were typically placed in separate containers and mounted on a nearby wall or walls. Thus, the installation of a dishwashing machine of the prior art required a substantial amount of labor.
Moreover, the machine, once installed, took up a substantial amount of space in the commercial estabIishment in which it was used. - -In dishwasher apparatuses of the prior art wherein the ~ ;
solid additives were fed off separate outside waterlines, a ;~
wasting of the solid detergent source and other additives often occurred. In use, such machines were typically first ~illed with several gallons of clean, hot water. The separate outside waterline directed to the solid detergent was then opened resulting in the formation of a detergent solution which flowed to the sump of the machine. However, since the machine had already been filled to capacity during the fill cycle, water would run out through the overflow valve as the detergent solution entered the sump. This resulted in a waste of hot water. In addition, some of the detergent solution would run out of the machine along with i;
the hot water, Thus, more detergent solution than necessary '.,'"''. ".:
. . ~ "': ~ ' .-"''''.'.",.''i`'''"'' 3 ~ 3 ~ 7 : -.:
had to be transported to the sump in order to make up for the amount lost through the overflow valve. Thus, a wasting of solid detergent occurred.
Inversion type detergent dispensing apparatuses which invert an open upright container of detergent to an inverted position over a nozzle which sprays water into the detergent container in order to produce a detergent solution are known. Known inversion type detergent dispensing apparatuses o~ the prior art such as those disclosed in U.S. Patent No. 4,020,865 and U.S. Design Patent No. ~44,598, both assigned to Applicant, relate to powder detergent dispensers useful in converting powder detergent ~rom 5 to 10 cylindrical gallon containers into concentrated detergent solution. The detergent dispenser disclosed in U.S. Patent No.

4,020,865 is not designed to function only with a particularly designed container as is the present invention, in which only containers having a particular shape including an indentation will cause the flip-top detergent dispenser of the present invention to properly function and water to spray onto the detergent product.
Furthermore, the user of the powder detergent dispenser disclosed in U.S. Patent No. 4,020,865 must manipulate a locking safety lever assembly out of locking engagement be~ore pivoting the inverted detergent container by means o~ a cradle assembly into an upright position. The manipulation of the locking safety ~5 lever assembly prevents water ~rom spraying through the product nozzle.
~ummary o~ ths Invention In accordance with the invention there is provided a dishwashing apparatus comprising a ~irst water access means having a valve and a vacuum breaker. The water access means leads into a main container, the main container having a means to access the main container in order to insert and remove dishware. A sump with a bottom portion is situated in a bottom portion of the main container wherein water and debris can collect in the sump. A ~irst nozzle is positioned within the main container in a manner such that pressurized water directed , ~ . ..

.::

13319~7 ~ 4 _ through the firsk nozzle would serve to contact dishware contained in the main container. A self cleaning first filker comprises a perforated cylindrical filter encased in a cylindrical metal casing having an open top portion and an open bottom portion. The top portion of the self cleaning first filter is attached to the bottom portion of the sump in a manner which would allow the flow of water and debris from the sump into the first filter by gravity and would allow the flow of water across the perforated cylindrical filter when access from the bottom portion of the first filter is closed by means of a drain valve. A drain valve is attached to the bottom portion of the self cleaning first filter wherein the drain valve when opened would allow the downward flow of water and debris out through the bottom portion of the self cleaning first filter in order to empty the dishwasher apparatus of all water and debris contained therein. A main pump is connected to the self cleaning first filter by a second water access means wherein water which has collected in the sump can be pumped by the main pump through the perforated cylindrical filter and through the second water access means. A third water aacess means leads from the main pump to the first nozzle and also to a second self cleaning filter, wherein the second self cleaning filter is designed such that water and debris aan flow by gravity through the third water access means into the main container when the main pump is deactivated. A fourth water access means has a valve and extends from the second sel~ cleaning filter and leads to a second nozzle pofiitioned in a solid additive container. The second nozzle is positioned such that pressurized water directed through the second nozzle would spray against a solid additive contained in the solid additive container in order to form an additive solution. A fifth water access means leads from the solid additive container into the main container in order to allow the flow of additive solution into the main container.
The dishwasher apparatus also permits the use of only one outside waterline instead of the more typical three. A main pump which is responsible for circulating water through rotating - 5 _ ~331g~7 nozzle arrays contained within the machine also serves to direct pressurized water to a solid detergent source and a solid rinse aid source. The use of a pump to feed water to the solid additive sources eliminates the need for the two extra waterlines of the prior art and also the pressure regulators, pressure gauges and vacuum breakers which wsre included on each waterline in order to maintain a constant pressure. This results in a substantial cost savings.
Savings on the cost of hot water and additives are also available. After a complete cycle of the dishwasher apparatus has been run, the final rinse water which contains both a rinse aid and a sanitizer is retained within the sump of the machine.
The user of the dishwasher apparatus can remove the clean dishware from the machine and insert soiled dishware for the start of the second complete cycle. The initial fill cycle which started the first complete dishwasher cycle by running two gallons of clean, hot water into the machine can be skipped at the beginning of this second complete cycle. The second complete cycle instead begins by recirculating the previously used rinse water left over from the first complete cycle through the rotating nozzle arrays and against the solid detergent source.
This results in a savings not only of hot water, but also of rinse aid and sanitizer.
The use of the dishwasher apparatus also permits a savings of detergent. The solid detergent dispenser mounted on top of the dishwashing machine of the present invention comprises a funnel-shaped metallic holder which serves to hold an inverted container of solid detergent having an opening in such a position as to allow water to spray through a nozzle located in the funnel-shaped metallic holder against the solid detergent in order to produce a detergent solution. Encircling the upper interior edge of the funnel-shaped metallic holder is a circular ;
metallic ring having a plurality of holes. A waterline connected to the ring serves to flush water out through the plurality of holes down into the interior of the funnel-shaped metallic holder into a l~ne leading to the sump of the machlne. This flushing '' ,.

-`` 3319~7 - action occurs at certain designated times in the dishwater cycle in order to ensure that any detergent that has conglomerated in the funnel-shaped metallic holder is flushed down the interior of the funnel-shaped metallic holder and transported to the sump.
This process helps insure that no wasting of detergent occurs. -Also, a use of only one outside waterline instead of the more typical three of the prior art enables a savings of additives such as detergent. In the present invention, the additives are fed by a pump with water contained in the sump of the machine rather than outside waterlines. Thus, the problem of losing clean,~hot water and additives down through the overflow valve which occurred in machines of the prior art is solved since no additional water is added to the machine to form additive solutions. Rather, additive solutions are formed only by using water which enters the machine during a fill cycle.
Thus, no wasting of clean, hot water or additives occurs with the use of the present invention. Furthermore, the dishwashing apparatus of the present invention is designed so that water containing detergent solution will not flow back into the incoming waterline.
In accordance with another aspect of the invention there is also provided a dispenser apparatus for use with a container having an indent. A base has an interiox and a rim. A nozzle ;~
i8 positioned within the interior of the base and flow of watar through the nozzle is controlled by a valve. A cam extends out over the rim of the base, the cam operatively connected to a switch situated such that application of vertical pressure downwards onto the cam causes the cam to move, thereby activating the switch, the switch operatively connected to the valve ;~
allowing water to flow through the nozzle. A container support i8 attached by a hinge to the base, the hinge designed to allow the container support to move from a closed position in which the container support rests upon the base to an open position. The i~
container support comprises in its closed position a first circular member ha~ing a space, the space of a size and location as to enclose the cam when the container support is in a closed _ 7 _ ~ 331 ~ 7 position without touching the cam. A second circular member is situated parallel and above the first circular member, the second circular member attached to the first circular member and the second circular member having a circumference larger than the first circular member. A protection means is attached to the container support, the projection means extending within and above a circular area defined by the first circular member and adapted to be positioned in an indent of a container. A
vertically extending support member having a top portion and a bottom portion, extends perpendicular to the second circular member. The vertically extending support member is attached at its bottom portion to the second circular member and is positioned such that when the container support is in an open position, the vertically extending support member is attached to a portion of the second circular member which is closest to the base member. A container base support is situated parallel to and above the first circular member and the second circular member and is attached to the top portion of the vertically extending support member. A handle attaches to the, container base support.
The flip-top dispenser of the present invention permits a safety feature which prevents water from spraying through the nozzle when no detergent container is present which could cause burns to the user. This safety feature of the present invention is more convenient than sa~ety features of known detergent dispensers.
A funnel-shaped metallic holder of the flip-top detergent, dispenser is in close proximity to a cam upon which a weight must press with sufficient ~orce before water will be pumped through the solid detergent source product nozzle. Such a~safety feature helps to ensure that hot water is not sprayed out th~ough the funnel-shaped metallic holder unless a particular shaped solid detergent source container is present into which the water will spray and helps to prevent burns since water will not spray out through the solid detergent source product nozzle unless the particular shaped solid detergent,source container is present to , - 7a - 133~7 push down the cam. If the user inadvertently forgets to insert ~ the solid detergent source container, then no water will flow through the solid detergent source product nozzle during the cycle, which otherwise could result in burns to the user or other nearby persons.
The detergent container support means of the flip-top detergent dispenser can comprise a wire cage assembly. Upon tilting the wire cage assembly of the flip-top detergent dispenser from a closed position in which the solid detergent source container is in an inverted position above the nozzle shaped metallic holder to an open position in which the detergent container is in an upright position, a cam which had been pushed down by the detergent container thus causing water to spray through the product nozzle is no longer contacted and thus water will no longer spray through the product nozzle.
The water is shut off, thus assuring safety but without having the user manipulate any lever before tilting the wire cage assembly of the flip-top detergent dispenser. The claimed dispenser is thus more convenient to use than known detergent dispensers while at the same time preserving a high level of safety by ensuring that water will not spray out of the product nozzle when no detergent container is present. Furthermore, the wire cage assembly of the flip-top detergent dispenser of the present invention permits the user to see the container while it is in the dispenser, thus allowing the user to see and read any warning labels and instructions printed on the container.
To insert the solid detergent source container into the ~unnel-shaped metallic holder, the wire cage assembly can be pulled downward by the use of a handle located on the top portion of the wire cage assembly from an initial closed upsidedown position tQ an open upright position. The solid detergent source container can be slipped into the wire cage assembly in its open position such that the solid detergent container is in an upright position with the open mouth of the container facing up. The user of the flip-top detergent dispenser can then push the wire cage assembly back into its initial closed upsidedown position 331 9~ :

in contact with the funnel-shaped metallic holder by use of the handle located on the wire cage assembly. The solid detergent source container is now resting in an inverted position with the bottom of the solid detergent source container up in the air and :`
the open mouth of the solid detergent source container positioned over the product nozzle positioned in the interior of the funnel~

:

` ~ 13~19~7 shaped metallic holder.
To remove the solid detergent source container, the user simply pulls down on the handle connected to the wire cage assembly so that the wire cage assembly is in an open upright position and thus, the solid detergent source container which was in an inverted position previously is now right side up. The user can now look down into the solid detergent source container and see the amount of detergent left. Previously with detergent holders of the prior art, a user would remove the inverted detergent source container by lifting it straight up out of its holder and often times look straight up into the container itself to see how much detergent was left. This was a dangerous practice since drops of detergent solution could flow out of the container resulting in injury to the user's eye. The present invention solves this problem in that the solid detergent source container is removed in an upright position wherein the user can easily look down into the solid detergent source container to see how much detergent is left and therefore must wait until the solid detergent source container is in an upright position before looking into it. This is in contrast to the prior art dispensers in which a user did not have to invert the solid detergent source container into an upright position before looking into it to see how much detergent was present.
Thus, the flip-top detergent dispenser of the present invention has numerous safety features. Automatic safety features include a cam situated next to the base means which will not be activated unless a particularly shaped detergent container is situated in the detergent support holder and the detergent support holder is closed. Only when the cam is activated can water spray up through the product noz21e.
Furthermore, spacers in the hinge means of the flip top detergent dispenser help prevent a user from catching or cutting his fingers when opening or closing the flip-top :.

In addition, a circular metallic ring having a plurality of holes is situated around the funnel-shaped interior Qf the base of the flip-top detergent dispenser. Water is flushed through the holes of the circular metallic ring at designated times in the warewashing cycle serving to insure that the detergent is rinsed down through the funnel-shaped interior of the base and that it does not conglomerate there resulting in a savings of solid detergent source.

Detailed Des~cription of the Invention 15A description of the warewashing apparatus of the present invention in its operation is as follows~
The warewashing apparatus of the present invention has a typical complete cycle of ninety seconds. The complete cycle comprises a number of shorter individual cycles. The length of the shorter individual cycles comprising the complete cycle and thus the length of the complete cycle itself can be shortened or lengthened. The first individual cycle is the first fill cycle which lasts approximately 14 seconds. The second cycle is the wash cycle which lasts approximately 44 seconds. There is a 5.4 second overlap of the end of the first fill cycle and the beginning of the wash cycle. Main pump 15 is activated throughout the wash cycle. Main pump 15 directs water to rotating nozzle arrays 20a and 20b and to other areas of machine l when appropriate valves are opened.
The wash cycle includes the following steps. ,A pre-flush step lasting 3 seconds rids fine in-line filter 17 of air and flushes water through holes in circular metallic ring 37 situated in the interior portion of funnel-shaped metallic holder 31 which contains solid detergent source container Z3.
Following the pre-flush step is a detergent solution ....: ., , "',"',: ', ~ ~

formation step lasting 2 seconds followed by a final flush step lasting S seconds in which water is again directed through the holes in circular metallic ring 37 to rinse out any detergent which has conglomerated in funnel-shaped metallic holder 31.
After the wash cycle is a 13 second drain cycle in which water and debris is drained from the machine 1. Before the end of the drain cycle, a second 14 second fill cycle~is initiated. An overlap between the end of the drain cycle and the beginning of the second fill cycle occurs for 3 seconds.
This 3 second overlap is termed the flush cycle. During the flush cycle, water enters machine 1 while water is also draining from machine 1.
The final cycle is the rinse cycle which last approximately 21 seconds. During the rinse cycle, chlorine sanitizer is added to sump 9 of machine 1 along with a rinse aid solution which is formed during the rinse cycle. During the rinse cycle, water is directed to rotating nozzle arrays 20a and 20b. At the end of the rinse cycle, the water containing sanitizer and rinse aid is~retained within sump 9 of machine 1 Referring to ~igures 1 and 10, access is gained to machine l by opening door 2 by means of door handles 3a or 3b. Soiled dishware can then be loaded into machine 1. Once soiled dishware has been properly placed within rack 4 of machine 1 and the system has been energized, the first of two fill cycle begins. Referring to Figures 1, 3 and 10, solenoid actuated on/off valve 5 opens to allow clean, hot water to flow through vacuum breaker 6 and through line 7 which leads into the top of machine 1 at point 8. The clean, hot water squirts out over the soiled dishware located in rack 4 and collects in sump 9.
Line 7 could be attached to other portions of machine 1 in order to deliver water to sump 9. However, by adding the water at the top of machine 1, it serves to contact the , " ~
'.' ".

133~9~7 - 12 - , soiled dishware with water, thus serving a rinsing function.
Solenoid actuated on/off valve 5 is operated by means of a cam 72 (not shown) in control cabinet 10 situated on top of machine 1. Cam 72 causes solenoid a~tuated on/off valve 5 to open for approximately 2 - 4 seconds allowing enough water through vacuum breaker 6 and line 7 to fill sump 9 with approximately two gallons of water. Electrical line 80 ~ extends from solenoid actuated on/off valve 5 to control cabinet 10.
Overflow valve 11 serves to prevent overfilling of sump 9. Excess water is drained through overflow valve 11 into line 12 which leads from the bottom of sump 9 into metal box 13 which is located beneath machine 1. Metal box I3 contains a perforated horizontal filter 14 which serves to . . j . .
collect food and other debris. Horizontal filter 14 can be manually removed and cleaned. Water draining through overflow valve 11 flows into metal box 13 through horizontal filter 14 and through a line (not shown) leading into the city sewer system.
~efore the 2 - 4 second first f^i~l cycle is complete, main pump 15 is activated by cam 73 (not shown) in control cabinet 10. The water which has collected in sump 9 is drawn by means of main pump 15 through coarse in-line filter 16 which is located beneath sump 9. Coarse in-line filter 16 comprises a perEorated metal cylindrical filter enclosed in a cylindrical metal casing. The upper edge of the perforated metal cylindrical filter is sealed to the cylindrical metal casing.
A drain valve ~not shown) is attached to the bottom of coarse in-line ~ilter 16. Coarse in-line filter 16 is positioned over metal box 13. The drain valve is not opened until later in the cycle. When the draIn valve is opened by means of cam 74 (not shown) in control cabinet 10i all water in machine 1 including the water within sump 9 drains down through coarse in-line filter 16 and fine in-line filter 17, : .. ' , , ,: ~ . .
.. .:. .

133~9~7 : ~-along with any debris that has collected in coarse in-line filter 16 or elsewhere in machine 1, into metal box 13 through horizontal filter 14, into a line (not shown) which leads to the city sewer system. Horizontal filter 14, located in metal box 13, serves to collect food and other debris.
Main pump 15 thus draws the water which has started to ~ collect in sump 9 through line 18, through coarse in-line filter 16, and directs the water through line 19 to rotating nozzle arrays 20a and 20b. Rotating nozzle array 20a, attached to t~e upper interior surface of machine 1, serves to deposit water down onto the soiled dishware contained in rack 4r Rotating nozzle array 20b, situated in sump 9 of machine 1, serves to spray water up against soiled dishware contained in rack 4.
Referring to Figures 2 and 3, solenoid valve 21a contained in box 21 is opened by means of cam 75 (not shown) in control cabinet 10 at the same time main pump 15 is activated. The opening of solenoid valve 21a serves two functions. The first function is to- allow air to b~ purged from fine in-line filter 17 situated above machine 1. Fine in-line filter 17 comprises a 40 mesh polyethylene cylindrical screen 17a encased within a cylindrical TPX
plastic housing 17b. Fine in-line filter 17 can be purchased from RON-VIC Company. Fine in-line filter 17 serves to trap food particles which can clog up solenoid valves 21a, 21b, and 21c contained in box 21, product nozzle 22 directed towards a solid detergent source in solid detergent source container 23 and the product nozzle directed toward rinse aid 24 in rinse aid container 25. Water enters fine in-line filter 17 from both the bottom of fine in-line filter 17 at point 17c and at the top of fine in-line filter 17 at point 17d. Water is pumped across polyethylene screen 17a exiting plastic housing 17b through line 26.
The second function of solenoid valve 21a is to al~low . ~ ,. . .

water to be pumped through line 27 to flip-top detergent dispenser 30. Flip-top detergent dispenser 30 comprises a nozzle shaped metallic holder 31 connected to wire cage assembly 32 by hinge means 33.
The solid detergent source (not shown) is contained within solid detergent source container 23. Solid detergent source container 23 has an opening 34. Solid detergent source container 23, containing solid detergent source (not shown), is positioned in an inverted position over product nozzle 22 contained in funnel-shaped metallic holder 31.
Solid detergent source container 23 is situated so that product nozzle 22 sprays water into solid detergent source container 23 through opening 34. A screen grating 35 surrounds nozzle 22 and prevents solid particles of detergent from flowing into line 36 leading to sump 9. Funnel-shaped metallic holder 31, secured to the top of machine 1, serves to hold solid detergent source container 23 in place along with wire cage assembly 32.
Referring to Figures 5 and 7, encircling the upper interior edge of funnel-shaped metal'llc holder 31 is a circular metallic ring 37 containing a plurality of holes (not shown). When solenoid valve 21a is opened, water is directed through fine in-line filter 17, through line 26, through line 27, and out through the holes in circular metallic ring 37 down through the interior funnel-shaped metallic holder 31 and into line 36 which leads to sump 9.
This flushing of water through the holes in circular metallic ring 37 serves to rinse out any detergent material which has collected in the interior of the funnel-shaped metallic holder 31 during a previous detergent solution formation cycle. Solenoid valve 21a is initially activated to purge fine in-line filter 17 of air and direct water through perforated circular metallic ring 37 in a preflush step to remove any detergent material left from a previous detergent solution formation cycle around the interior of the ' ~,:
'~. :

- 15 - 13 31~ ~ 7 funnel-shaped metallic holder 31.
Immediately after solenoid valve 21a is opened and fine in-line filter 17 is filled with water and purged of air solenoid valve 21a is closed and solenoid valve 21b is activated by cam 76 (not shown) in control cabinet 10 allowing water to flow through line 28 where it is sprayed through product nozzle 22 onto- the solid detergent source (not shown).
The action of the water on the solid detergent source ; 10 results in the formation of a detergent solution which flows through line 36 into sump 9. Solenoid valve 21b is then deactivated after 2 seconds have elapsed. Solenoid valve 21a is then reactivated for 5 seconds in a final flush step.
After the detergent solution reaches sump 9, it is pumped out along with any water contained in sump 9 by means of main pump 15 through coarse in-line filter 16 through line 19 to upper and lower rotating nozzle arrays 20a and 20b where it is sprayed onto dishware located in rack 4 and collects in sump 9 to be recirculated. The water and detergent solution sprayed onto the d~shware located in rack 4, collects in sump 9, passes through coarse in-line filter 16 and is recirculated by main pump 15 through rotating nozzle arrays 20a and 20b for 42 seconds until the wash cycle ends.
The wash cycle ends 42 seconds after the initiation of the Eirst fill cycle. A solenoid valve contained in box 38 connected to the side of coarse in-line filter 16 is activated by cam 74 (not shown) in control cabinet 10 causing water and debris to drain from machine 1 into metal box 13 through horizontal filter 14 into a line (not shown) directed to the city sewer system. Debris contained in coarse in-line filter 16, fine in-line filter 17, and elsewhe~re in màchine 1 exits through a drain valve (not shown) connected to the bottom of coarse in-line filter 17 through metal box 13 located under machine- 1 where it is trapped by horizontal ',~ '''' ''~ :'' ',~ :.,~ ~' ' '.', :

Next, a second fill cycle is initiated by cam 72 (not shown) in control cabinet 10. Clean, hot water again flows through solenoid actuated on/off valve 5, through standard vacuum breaker 6, through line 7, through the top of machine 1 at point 8 spraying onto dishware located in rack 4 and collecting in sump 9.
ApproximateIy two gallons of clean, hot water flows into sump 9 during the second fill cycle. Before the completion of the second 'fill cycle which lasts approximately 14 seconds, main pump 15 is activated by cam 73 (not shown) in control cabinet 10. Main pump 15 draws water through coarse in-line filter 16 and directs it through line 19 to rotating nozzle arrays 20a and 20b. Solenoid valve 21c is then opened for approximately 6 - 8 seconds by means of cam 77 (not shown) in control cabinet 10 allowing pressurized water to flow-through fine in-line filter 17 at points 17c and 17d, and out through line 26. The water is then pumped through line 29 and is sprayed by a product nozzle onto rinse aid 24 contained within rinse aid container 25 which is situated on top of machine 1. A rinse aid solution is formed by the contact of water sprayed through the product nozzle onto rinse aid 24. The rinse aid solution thus formed flows through line 39 into sump 9.
Referring to Figures 1, 2 and 10, rinse aid container 25 comprises a clear cylinder 40 havi'ng a flip-top lid 41, through which the solid rinse ai'd 24 itself is inserted ihtO
rinse aid container 25. The clear cylînder 40 allows the user of the dishwasher apparatus to determine by visual inspection the amount of rinse aid 24 present in rinse aid container 25.
The base ofi rinse aid container' 25 comprises a cylindrical metal base 42 having a series of four circular screens situated in the top interior portion thereo. The ~ 13319~7 screens vary in coarseness with the top screen being the finest, and each successively lower screen being coarser, the lowest screen being the coarsest. The screens serve to support solid rinse aid 24 in rinse aid container 25. A
key-hole shaped hole in the center of cylindrical metal base 42 allows the user to observe line 39 through which rinse aid solution flows into sump 9.
At the same time solenoid valve 21c is opened and rinse aid solution is being formed, sanitizer pump 43 is activated by cam 78 (not shown) in control cabinet 10. Referring to Figure 3, sanitizer pump 43 serves to pump a liquid sanitizer such as chlorine from a container 44 through line 45 into sump 9 at ;point 46. Sanitizer pump 43 remains on for 6 seconds to allow the addition of 8 milliliters or 50 - 60 ppm. of chlorine into sump 9. At this point in the cycle, both chlorine sanitizer and rinse aid solution have been added to water contained in sump 9.
Main pump 15 serves to continuously pump water through rotating nozzle arrays 20a and 20b for the duration of the 18 second rinse cycle. When the rinse cycle is completed, main pump 15 is stopped by means of a cam (not shown) in control cabinet 10. The rinse water which contains both sanitizer and rinse aid is retained within sump 9. The 90 second complete cycle has now been completed. Door 2 of machine 1 can be opened to remove clean dishware from rack 4. Dirty dishware can now be properly inserted in rack 4 of machine 1 in order to begin another cycle.
At the beginning of the next complete cycle, a first fill cycle is not necessary since two gallons of water have been retained in sump 9 from the previous rinse cycle. The second complete cycle is begun by recirculating water containing rinse aid and sanitizer retained in sump 9 from the first complete cycle by means of main pump 15 through coarse in-line filter 16, through line 19 to rotating nozzle arrays 20a and 20b. Solenoid valve 21a is opened to purge :

Solid detergent source container 23 also has a pronounced second rim 56 extending around the upper edge of cylindrical portion 50. Second rim 56 helps to ensure that : :

, ~

1331~7 solid detergent source container 23 does not slide completely through wire cage assembly 32 further than second rim 56 as wire cage assembly 32 is opened and closed by the user. Wire cage assembly 32 catches solid detergent source container 23 at second rim 56 and prevents solid detergent source container 23 from completely sliding through wire cage assembly 32.
Wire cage assembly 32 is attached on either side to rotating flanges 49a and 49b respectively. Rotating flanges 49a and 49b are attached to stationary flanges 48a and 48b respectively. Stationary flanges 48a and 48b are also attached at their opposite ends to nozzle shaped metallic holder 31. S~acer 47a is positioned between rotating flange 49a and stationary flange 48a and spacer 47b is positioned between rotating flange 49b and stationary flange 48b.
Spacers 47a and 47b help ensure that a user does not cut or catch his fingers in hinge means 33 when opening or closing flip-top detergent dispenser 30.
Wire cage assembly 32 comprises a first circular metallic ring 57, said first circu~ar metallic ring 57 positioned to contact unnel-shaped metallic holder 31 when flip-top detergent dispenser 30 is closed, said first circular metallic ring 57 having an opening o approximately one-half inch at point 58, where ends 57a and 57b of first circular metallic ring extend upward and contact second circular metallic ring 59 at points 59a and 59b respectively.
Second circular metallic ring 59 is of a slightly larger circumerence than first circular metallic ring 57.
A double cross bar 60 extending between first circular metallic wire 57 and second circular metallic wire 59 has two inwardly projecting projection means 60a and 60b. A third wire 61 positioned parallel to and above the first and second circular metallic wires 57 and 59 forms a semi-circular portion of wire cage assembly 32. A fourth wire 62 extends from two points on a diameter of first circular metallic wire ' , ~ - ~ 3 3 1 9 ~ 7 57 and extends upward contacting second circular wire 59, third wire 61, extending above third wire 61 approximately two inches and curving into a semi-circular shape, where it forms a base 62a which serves to support the base 69 of solid detergent source container 23 when the flip-top detergent dispenser 30 is in an open position.
Fifth wire 63 extends from point 57a and 57b of first circular metallic wire 57 upwards contacting second circular metallic wire 59, third wire 61, to points 62a and 62b of the semi-circle formed by fourth wire 62 from which it extends to form handle 64 of wire cage assembly 32. Sixth wire 65 extends from first circular metallic wire 57 at point 57c and contacts second circular metallic wire 59 and third wire 61 and extends up to the center of the semi-circular portion of lS fourth wire 62.
Wire cage assembly 32 has two projection means 60a and 60b extending inward into the circular space defined by second circular metallic wire 59. Projection means 60a and 60b correspond in shape to curved vertical indention 55 of solid detergent source container 23. Wire cage assembly 32 has an opening at point 34 defined by second circular metallic wire 59 and ends 57a and 57b of first circular metallic wires 57. When the flip-top detergent dispenser 30 is closed, and no so}id detergent source container 23 is present, the open space 58 in wire cage assembly 32 is positioned over cam 66 in such a manner that it does not contact cam 66. Thus, flip-top detergent dispenser 30 by itself when closed does not function to contact cam 66.
~owever, when an appropriate solid detergent source container 23 designed for use in said dispenser 30 is inserted into said flip-top detergent dispenser 30 such that projection means 60a and 60b are lined up with the curved vertical indention S5 of solid detergent source container 23 and said wire cage assembly 32 is closed, said solid detergent source container 23 slides downward through wire " ~

~'.,',. :', 1 3 3 1 ~ ~ 7 - 22 - ~ -- : ~ . - . .
cage assembly 32 towards nozzle shaped metallic holder 31 as the wire cage assembly 32 is tilted past the horizontal.
First circular metallic wire 57 is ,designed with a smaller circumference than second circular metallic wire 59.
Thus, solid detergent source container 23 can slide past second circular metallic wire 5'9 but is stopped by first circular metallic wire 57 at second rim 56 of solid detergent source container 23, said first circular metallic wire 57 , having a smaller circumference than the circumference of second rim 56 and cylindrical portion 50 of solid detergent source container 23.' Thus, when wire cage assembly 32 is closed, the top of second rim 56 of solid detergent source container 23 rests on first circular metallic wire 57. Space 58 is; now occupied by solid detergent source container 23. As the wire cage assembly 32 and solid detergent source ,container source 23 are closed, cam 66 is contacted by said solid detergent container 23 which occupies ,space 58, activating a microswitch enclosed in enclosure 67 allowing water to flow through product nozzle 22. Insulated cable 68 leads from enclosure 67 to control cabinet 10.
The irst circular metallic wire 57 serves to catch solid detergent source container 23 as the wire cage assembly 32 is lifted and pushed orward s'o that solid detergent 25 ,source container 23 does not come 1ying out through wire cage assembly 32 as wire cage assembly 32 is closed.
The wire cage assembly 32 is also advantageous in that it allows the user to look through the wire cage assembly 32 at the solid detergent source container 23 to identify the product by means o product labels and to read any directions or warnings printed thereon. Also, preerably solid detergent source container 23 is clear or transparent so that the user can determine the amount of solid detergent source let by looking through the clear or transparent container 23 while container 23 is situated in place on machine 1.

To remove solid detergent source container 23 from wire cage assembly 32, the user first pulls down on handle 64 on wire cage assembly 32 so that wire cage assembly 32 is in an open position. To remove solid detergent source container 23 from now opened wire cage assembly 32, the user merely grasps handle 71 attached to base 69 of solid detergent source container 23 and lifts the solid detergent source container 23 very slightly, tilting the bottom of solid detergent source container 23 towards the user and the top of solid detergent source container 23 away from the user~and thus pulling solid detergent source container 23 out of wire cage assembly 32.
To insert solid detergent source container 23 into wire cage assembly 32, the user merely lines up the vertical indentation 55 on solid detergent source container 23 with projection means 60a and 60b on wire cage assembly 32 and holding onto handle 71 of solid detergent source container 23 sIides solid detergent source container 23 into wire cage assembly 32 by tilting the top of solid detergent source container 23 away from the user and s~l.iding solid detergent source container 23 up into wire cage assembly 32, with projection means 60a and 60b moving within indentation 55, with base 69 oE solid detergent source container 23 sliding back down to rest on the semi-circular portion oE wire 62 of wire cage assembly 32.
When flip-top detergent dispenser 30 is in an open position, the user can slide the upright solid detergent source container 23 out oE wire cage assembly 32 according to the previously described method and then look down into the opening of the removèd solid detergènt source container 23.
The solid detergent source container 23 is in an upright position after removal. Thus, a user can immediately look down into the solid detergent source container to determine the amount of solid detergent source left.
If the user had to determine the amount of detergent ~ 1 3 3 1 9 ~ 7 left in an inverted solid detergent source container not encased in Applicant's flip-top detergent mechanism, the first instinct of the user would be to lift the container straight up and look directly up into the inverted container which could result in damage to the user's eyes from drops of detergent solution present in the solid detergent source container. Thus, the flip-top mechanism detergent dispenser aids the user in that it inverts the solid detergent source container before the user has an opportunity to look into the container.
Other modifications of the invention will be apparent to those skilled in the art in light of the foregoing description. This description is intended to provide concrete examples of an individual embodiment clearly lS disclosing the present invention. Accordingly, the invention is not limited to this embodiment or to the use of specific elements therein. All alternative modifications and variations of the present invention which fall within the spirit and broad scope of the appended claims are covered.
