DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hot liquid heating and dispensing device for heating and dispensing liquids such as coffee, tea, or water.

BACKGROUND OF THE INVENTION Devices for heating and dispensing a single type of liquid, such as coffee, tea, or water, are well known. However, given the choice of multiple hot fluids, multiple devices are currently required.

(Problems to be Solved by the Invention) Therefore, in the conventional device, it is not possible to dispense a plurality of different hot liquids, such as coffee, tea, hot water, etc., with one device.

SUMMARY OF THE INVENTION A heating dispensing device for multiple liquids according to the present invention includes a housing containing a plurality of independent liquid heating dispensing units.

(Functions and Effects) With this structure, a device capable of dispensing a plurality of different hot liquids, such as coffee, tea, hot water, etc., can be easily and compactly formed.

The device has one hot water unit and two coffee/tea making units.

At least one of the above independent units is
It is partially removable from the device body so that liquid can be dispensed remotely from the device body. The independent units each have a liquid heating section and a liquid storage dispensing section, and the coffee/tea production unit has a brewing section.

the liquid storage dispensing portion is separable from the device body;
Meanwhile, the heating section and the coffee/tea receiving section of each coffee/tea production unit are fixed within the apparatus body. The removable part of the unit is separated and the temperature decreases by 5°C52°C1 or 1 hour.
below °C.

This separation structure is described below. That is, the removable parts are each surrounded by a separate foam layer, and the water inlet of each removable part has steam trap means for preventing the escape of steam from the interior of the removable part to the outside. Furthermore, the removable part plug has its valve housed within the outer wall of the removable part. The housing of each valve is made of plastic material. The outlet of each plug is located within the housing as far as possible from the outer wall of the removable part, to facilitate removal.

The display section of this device is capable of various operations and warning displays. For example, it is possible to provide a scale warning device for each independent unit, as well as a dangerous water pressure warning device for the main body of the device.

Another aspect of the invention is a liquid heating dispensing device having a housing and a liquid dispensing stopper, the stopper having a valve contained within an outer wall of the housing.

In yet another aspect of the invention, a liquid heating dispensing device includes a container for storing a hot liquid, the container having vapor trap means for preventing escape of vapor from the interior of the container to the outside.

(Example) As shown in Figure 1, the box-type compounding device is

ing.

Cold water is supplied to the tank 20 through a conduit 36 which extends upwardly towards a T-junction 38 directly above the upper water level 40 .

The upper end of this conduit 36 is at the T-shaped connection 38;
Also, its lower end terminates at a water flow controller 42.

This controller 42 is for preventing a sudden increase in pressure and is similar to conventional ones on the market.

Said conduit 36 forms a container for a small but important amount of cold water. Another conduit 44 extends inwardly from the T-shaped connection 38 into the tank 20 and has an outlet 50 connected to the tank 20.
The tube 52 is located at the center of the tube 52 and extends downward. Furthermore, an air brake is provided at the tip of this tube 52, and cold water is supplied through the tube 52 to a position near the thermostat 26.

At the top of the tube 52 a steam trap means 51 is provided, which is located directly below the outlet 50 of the conduit 44. Two embodiments of this steam trap means 51 shown in FIGS. 4 and 5 will be described in detail later.

The final conduit 46 of the T-connection 38 extends upwardly into the air from the hole 48 to prevent backflow of the wicking water flow.

A solenoid valve 54 is connected to the water flow regulator 42 and is controlled by the controller 28 to open or close the main cold water flow from the supply conduit 56 .

The thermostatic temperature control device 60 of the heater 24 can be set in the range of 50°C to 95°C. or,
A temperature safety shut-off device 62 is provided at the bottom of the heater 24.

The housing 18 is provided with a window 68, which allows the user to see the water level in the pipe 66, which approximately corresponds to the actual water level in the tank 20.

The cross section of the pipe 66 is designed to minimize heat loss.
It is formed extremely small compared to the cross section of the tank 20. The pipe 66 also connects the tank 20. '＞It extends from the bottom, but this is also to minimize heat loss. This is because the heat within the tank 20 is difficult to flow downward.

The other two units configured as coffee/tea making units are each equipped with a heater 10, as shown in FIG.
2. Spray tip 104 and coffee pouring container 106
, all of which are supported by the housing 18.

Chilled water is supplied to the inlet 108 of the heater 102 by a bendable pipe or conduit 110. The heated water is further discharged from the heater 102 through an outlet 112;
It then flows into a bendable pipe or conduit 114. This pipe or conduit 114 extends above the spout tip 104 which is disposed above the coffee pouring container 106 . At the rear of the heater 102,
An electrical heating element 116 is provided having electrical leads extending from the tip of the heater and further connected to an electrical member (not shown). The heater 102 is
It is laterally supported by hinges (not shown) on its own dedicated support member, which can optionally be attached to said unit 1.
This is to make it possible to take out 2 or 16 other constituent members.

The heater 102 is covered by a circular cover plate 120, and the cover plate 120 is provided with the inlet 108 and the outlet 112.

Additionally, the cover plate 120 is secured to the heater by a wing nut 122 that connects to a central boss 124 of the heater.

The heater 102 has a drain plug 126, which is connected to the bottom of the heater and opened as needed to drain water in the heater.

The units 12 and 16 further include a removable storage and dispensing container 130 with a drain tap 132. The container 130 has an outer wall 134 and an inner wall 136, between which is provided a separating foam material (eg, British Patent Publication No. 1403861). The container inlet 138 is located below the container 106 outlet (when contained within the housing 18) and has vapor trap means 140.

Therefore, the container 130 is independently separated, so that the temperature decrease per hour is only 1°C to 1.5°C.
°C, and the container can be removed from the device body 10 to dispense coffee/tea as far away from the device body as possible.

Said vessel 130 has water level indicating means 64 very similar to that shown in FIG. 2 above.

Two embodiments of the steam trapping means 51 and 140 are shown in more detail in FIGS. 4 and 5. In FIG. 4, the tank 20 or container 130 has a screw-mounted lid 142 to which a tube 144 extending downward is connected to supply hot water to the tank 20 or container 130. (See Figures 2 and 3). A pipe 146 is provided in the center of the lid 142.
The inlet 138 is formed by a pipe 146 extending into the center of the tube 144 . A U-shaped trap member 148 is supported directly below the pipe 146, and this trap member 1
Both sides of the pipe 48 extend slightly above the lower end of the pipe 146 (see reference numeral A in FIG. 4). The above structure functions as a steam trap. This is because the hot water flowing into the tube 144 through the pipe 146 forms a liquid layer in the U-shaped trap member 148 and flows out from the interior of the tank 20 or the container 130 through the inlet 138. This is because it prevents steam from flowing. To prevent pressure build-up within the tank 20 or the container 130, very small outlets 145 and 147 are provided.
They are arranged in tube 144 and pipe 146, respectively.

As shown in FIG. 5, the tank 20 or container 130 has a screw-mounted lid 142, which includes:

In the center of the lid 142, the injection port 138 is formed by a hole in the lid, and the tip of the tube has a protrusion 148' on which a trap ball 150 is placed.
is supported. And when hot water is not flowing through the inlet 138, this ball 150 is inserted into the protrusion 148.
', and the tank 20 or container 13
This prevents steam from flowing into the inlet 138 from inside the tank. on the other hand,
When hot water is flowing into the inlet 138, this ball 150 disengages from the protrusion 148' and directs the water into the tube 1.
Pour into 44. At this time, the ball 150 is connected to the pin 152
It is held within the inlet 138 by the injection port 138.

The lid 142 also has a very small vent hole 154 to prevent pressure buildup within the tank 20 or container 130.

FIG. 6 shows the plugs 22 and 1 shown in FIGS. 1 and 3.

It has 158. This valve mechanism 158 has a vertical shaft 160 made of brass, and this shaft 160 further has a valve mounting material 157 made of brass for a valve member 159 made of silicone rubber.

A handle (not shown) is attached to the other end of the shaft 160. The valve member 159 is biased by a spring 161 against a valve seat 162, which forms part of the bung housing part near one or 134 of the inner wall of the unit 12.14 or 16. . An O-ring type seal 164 is also provided to seal the spring 161 from liquid passing through the plug.

The outlet 166 of the plug is located as far as possible from the outer wall 21 or 136 of the unit 12.14 or 16, in order to facilitate removal. The outlet 166 is further provided as close as possible to the outer wall 168 of the stopper, with respect to which a projection 170 is provided extending into the outlet 166 for supporting the shaft 160. There is. It is also possible for a dispensing tube 172 to extend from this outlet 166.

To dispense water from the tap, the handle (not shown) may be operated to move the shaft 160 outwardly, thereby lifting the valve member 159 from the valve seat 162. Then, the water from the container 130 flows through the valve member 159,
through the housing 156 and finally the outlet 16
It comes out from 6.

By encasing the valve seat 162 within one of the exterior walls or 136 of the unit, and by providing the spigot with a plastic housing 156, heat loss from the spigot to the water within the unit is minimized.

FIG. 7 shows the display panel 174 shown in FIG. 1 in more detail. This panel 174 for the three units 12, 14 and 16 includes a plurality of warning lights 176, an on/off switch 178, an option switch 180, an indicator switch 182, and a liquid level scale 184.

As shown in FIG. 8, the pressure warning device 186 includes a housing 187 containing a diaphragm 188 made of silicone rubber.

A spring 194 is disposed around the faucet 192 to bias the disc 190 against the diaphragm 188 while the other end 196 of the faucet 192 is in contact with a microswitch 198. During use,
Water for the device 10 passes through an inlet 200 in the housing 187, pushes the diaphragm 188, and connects the disc 190 and faucet 192 to a microswitch 8.
Move it to the side. In the unlikely event that the water pressure becomes dangerously high or low, the microswitch 198, which has a predetermined scale, is activated to give an appropriate warning.

FIG. 9 shows scale warning device 202 in conjunction with heating material 203, which device 202 is connected to contact member 2.
It has a thermistor 204 that meshes with 05. In use, if the water level reaches an unacceptable range, the heating material 203 is heated above its normal operating temperature, which the thermistor senses and electronically converts to a predetermined level. compared to , this gives appropriate warning.

Instead of the cast material heater 24 of the central unit 14, a heating material 252 as shown in FIGS. 10 to 12 is used.
It is also possible to use a heater machine WE250 with
