The apparatus shown in Figures l and 2 is a 10 manually filled brewing apparatus having an infuser pan
2, a spray head 4 and a conduit G leading from the spray head to the top of a hot water tank 8, the conduit 6 connectinc3 as a siphon tube from the top of the tank. The tank has a heater element lo, an upper 15 thermostat 12 and a lower thermostat 14. Upper thermostat 12 is located about a third of the way down from the top 16 of the tank so as to measure the temperature (which when hot is between about 90 and 95C) and the top third of the volume of the tank is 20 equivalent to a water charge for one infusion charge for receptacle 20 positioned below the infuse pan 2.
Thermostat 14 is arranged to measure the water temperature at the bottom of the tank between about 92 and 97~.
Above the tank is a manual filler tank 22 . , , .
Jo I
4' connected via a conduit 24 to a T- junction 26, the upper leg 28 of which opens into an inlet 30 of the tank. The lower leg 32 of the T-junction extends downwards to a drain plug 34. At the top of the tank is an air outlet 36 connected via a conduit 38 to an inlet 40 at the top of filler tank 22. baffle plate 50 is provided above inlet 30 to divert the rising water during a filling operation away from the centre of the tank and maintain the water in the tank 10 stratified, i.e., in distinct strata of jot and cold water Jones.
The operation of the apparatus shown in Figures 1 and 2 is as follows:-The tank 8 is filled manually through tank 22 lo and the heater element 10 is switched on. As the temperature of the water rises, the hot water rises to the top of tank 8 until thermostat 12 indicates by means of water ready lamp 46 that the top of the tank has reached infusion temperature. At this state a 20 first charge is ready for an infusion operation which is commenced by pouring an additional charge of water into filler tank 22. This water feeds into the bottom of the tank through conduit I displacing the hot water out of the top of the tank through conduit 6.
25 Because of the baffle plate 50 the cold water entering 'I,' .
I
the tank is encouraged to remain in a distinct strata at the bottom of the tank and therefore the amount of gold water mixing with the hot water is minimal and hence the temperature ox the water at the top of the tank is kept high whilst the heater at the bottom of the tank brings the temperature of the cold strata up, in this way several infusions can be achieved in rapid succession depending on the size of the tank. The infused coffee or tea then percolates through the 10 inure pan into receptacle 20. The brewing apparatus is preferably left on so that the water in the tank continues to heat up until thermostat 14 reaches a temperature of I to 97 and then by means of controller 42 cuts off power to heater element 10.
15 Fakers 3 to 6 show an automatically filled brewing apparatus having a similar hot water tank 8' infuser pan 2' with spray head 4' and tank to spray head connecting siphon conduit G'. The tank also has an upper thermostat 12' and lower thermostat 14' with heater element 10', a deflector plate 50' above inlet 30' and a vent 36' opening at 40' into a filler tank 22'.
The main difference between apparatus shown in Figure 3 and that shown in Figure 1 is the provision of 25 a water means connection 60 leading to a water inlet ; .; ' ~L~3'79111:~
6' solenoid valve I connected by conduit 64 to an inlet I in filler tank 22'. Filler tank 22' has an outlet conduit I connecting to heater tank inlet 30'. The water draw-off tap 68 on the side of the casing 70 of the apparatus is connected via an isolation solenoid valve 72 to a conduit 74 connected in turn to a water outlet 76 in the top third of tank 8'.
An emergency overflow pipe I provides an i emergency outlet I from the filler tank 22' to vent 10 through the apparatus to an outlet 84 below the apparatus. This is in case ox failure of valve 62 remaining open so that water can overflow through the apparatus without damaging any electrical equipment.
on infusion switch I and water ready lamp I
15 are mounted on the side ox casing 70. A machine on/off switch 90 and top heater switch or switches 92 are also mounted on side of casing 70. The circuit diagram for an automatic brewing apparatus without a side water draw-off tap is shown in Figure 7 and includes a 20 thermal cut-out 100 which operates to disconnect the electrical supply to the main heater lo if the apparatus overheats.
When the apparatus is first to be filled with water a manual fill switch 1~2 is moved from the 25 position shown in Figure 7 to make a circuit through ' Jo ~3'7~
the solenoid 104 of the water inlet valve 62 so that tilts is opened allowing water from the mains supply to enter the filler tank 22' until the apparatus is full.
Tile fill switch 102 is then moved to the position shown in Figure 7. In this position the main boiler heater element 10' is energized through the bottom thermostat 14' to heat the water in the tank. When the water in the upper portion of the tank above the probe of the upper thermostat 12' has been heated to the desired 10 temperature, the thermostat 12' operates from the position Shannon Figure 7 to make with the contact 106. The water ready light 88 is then lit showing that an infusion operation may take place.
When the infuse switch I is momentarily 15 closed, the relay 108 is energized moving the switch 110 Erom the contact shown to a second contact 112. When in this position the relay 108 is energized through the connection 112 to keep the switch in that operative position. The solenoid 104 is then operated through I the switch 110 and a further switch 114 to open the water inlet valve to allow water to enter the water filling tank from the mains. Infusion then takes place until the water level reaches the high level probe 116 in the water filling tan whereupon the switch 114 is 25 operated to open the connection between -the solenoid I
104 and thy neutral line thus closing the water inlet valve 62.
When the whole tank has reached the desired water temperature, the bottom thermostat 14' operates to de-energise the boiler heater element 10'.
Manual switch 11~ is provided to energize a bottom warmer element 120. HeatincJ elements 122 for the top warmer elements are energized on closure of switches 92.
The infusion switch I cannot be operated to open the water inlet valve until -the water ready light I is lit and able to pass current. pence, coffee infusion cannot take place until the water is at the desired temperature.
It will of course be appreciated that a mains on/oEf switch for the boiler heatirl-3 element may be provided if desired.
The wiring diagram illustrated in Figure 8 is similar to that described with reference to Figure 7 Z0 except that it illustrates the apparatus with a side water draw-off tap.
when the water in the top portion of the boiler tank is being heated two the desired temperature, a tap isolation valve 72 remains closed with the solenoid 25 eneryised, the circuit being made through the top Jo ` ,.~' ~2~17~09 thermostat I the relay switch 110 and the level switch 114. When the top thermostat 12' is operated to make the circuit tllrouyh the water ready lamp then the circuit through the solenoid of the valve 72 is broken at the top thermostat, and thy valve 72 is opened allowing hot water to be drawn off from the tap. When the thermostat 12' operates to change the switch 106 because the water in the top portion of the boiler tank has dropped below the required 10 temperature then the valve 72 again closes.
When waiter is being drawn off thrill the tap, the water level drools 'below a level probe 124 located in the top of the boiler between the point of take off for the spray tread and the point of take off for the 15 tap. When the water level drops below this probe, a switch 126 moves 50 as to complete the circuit Thor the solenoid lug of thy water inlet valve Go so as to open this valve. Water then enters the apparatus until the level reaches the low water probe I in the water 20 filling tank which operates the switch 12G, where upon the circuit to the water inlet valve 62 is made by causing the water supply to be shut off.
When the infusion switch I is pressed the isolation solenoid valve 72 is closed by the hold-on 25 switch 13~ by operation of the coil 132 within the ' :`;

10 ' boiler control unit. This prevents water from being drawn off through the tap during infusion of coffee or tea. A twill on-off switch 90 with indicator lamp may be provided (see Figure 9).
