Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hot water storage type coffee maker that boils water in a tank equipped with a heater and uses this hot water to brew coffee.

Conventional configuration and its problems Traditionally, in coffee makers that store and drop hot water, a cylindrical part is provided at the bottom of the hot water tank in order to prevent dry cooking and improve productivity, and a space heater is wound around the cylindrical part in a band shape. A fixed configuration was considered.

With this configuration, if the outlet is provided on the bottom of the hot water tank other than the cylindrical part, when hot water is used normally, water will remain in the cylindrical part, which can prevent the heater from running dry. There is. However, simply providing the cylindrical parts in series in the height direction has the disadvantage that the height of the cylindrical parts is added to the height of the chamber or decanter, increasing the height of the entire coffee maker. there were.

In addition, in a push-up type coffee maker, the hot water tank can be installed at floor level, which has the advantage of reducing the overall height of the coffee maker. However, on the other hand, not only does the depth become larger, but when supplying hot water, it is necessary to supply water with a water supply cup to push up the hot water, and when draining water, the drain port is located low from the floor, so the main body of the coffee maker must be moved. However, it had the disadvantage that it was necessary to prepare a container at a position lower than the drain.
.

OBJECTS OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to provide a hot water storage type coffee maker which is small in overall size and can be easily drained without having to move the main body.

Structure of the Invention The present invention forms a first dripping port in a part of the bottom of a hot water tank, forms a hanging cylindrical part in the other part of the bottom, and wraps a heater around the cylindrical part. Two drip ports were formed, a chamber was placed below the first drip port, and containers were placed below this chamber and below the second drip port, so that the cylindrical portion and the chamber were placed parallel to each other, and the whole It is smaller in size, allows drainage from the trench and second drip opening, and is easier to operate.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, 1a is a first front plate, 1b is a second front plate, and 1C is a third front plate, each of which is fixed by spot welding and is integrally constructed, and constitutes the front plate 1. 2 is an outer plate, which is fixed to the front plate 1 with screws. 3 is the back plate, outer plate 2 and third front plate 1C
It is fixed with screws.

4 is a bottom plate, which is fixed to the third front plate 1C with screws.

A first cover 6 is fixed to the first front plate 1a. 6
is a scattering plate, which is detachably attached to the first cover 6. 7 is a chamber, and in the center of this bottom there is a dripping lower a.
is provided and slidably attached to the first cover in a detachable manner.

8 is a container with a handle Sa.

It is composed of a band 8b and a glass container 8C.

A warmer 9 is fixed to a burring hole of the third front plate 1C, and has a built-in heater (not shown) to keep the container 8 warm. 1o is a second cover with a hook 10a and a protrusion 1
Holes 1d are formed in the first front plate 12L and the second front plate 1b by utilizing the elasticity of the material.

1e, and can be easily attached and detached without using metal fittings such as screws. 11 is a hot water tank, which has a cylindrical part 112L for residual water on one side of the bottom;
A heater 12 is fixed to the outer periphery of 1a. Cylindrical part 1
On the bottom of the hot water supply tank 11, there is a thermostat 13 for controlling the temperature of the water in the hot water tank 11, a temperature fuse 14 fixed with screws to prevent abnormal temperature rise, and a hot water supply nozzle 16 and a drain pipe. 16 are each fixed by welding. The hot water pipe 15 includes the cylindrical portion 11a.
It has a structure that stands out from the inside. Reference numeral 11b denotes a drip opening, and a solenoid valve 17 located at the drip opening 11b and provided on the bottom of the hot water tank 11 is fixed to the hot water tank 11 via an O-ring 18. Support legs 19 are fixed to the hot water tank 11 by spot welding, and are fixed to the first front plate 1a with screws. A hot water tap 20 is composed of a first rotating shaft 208L and a second valve body 20b, and is rotated by a threaded portion to open and close the valve. 21 is a drain plug, which includes a second valve body 21b, an O-ring 210, and a valve seat 2.
The second rotating shaft 21a and the second valve body 21b are rotated by a threaded portion to open and close the valve. 22 is hot water pipe 15
A first connecting pipe 23 communicates between the drain pipe 16 and the hot water supply valve 20, and a second connecting pipe 23 communicates the drain pipe 16 and the drain valve 21.

24 is a leg fixed to the bottom plate 4. 26 is a lid for water supply, and a lid backing 26 is attached thereto. 27 is a tank backing that keeps the outer panel 2 and the hot water tank 11 airtight. 28 is a power switch, and 29 is a switch for the warmer 9.

30 is a start switch when brewing coffee, and in operation, the solenoid valve is energized for about 180 seconds by a timer function, and about 1500cc of hot water can be discharged. 31 is a stop switch used when the start switch is pressed by mistake and the extraction is stopped.

The operation of the above configuration will be explained.

First, open the lid 26, supply water, and turn on the power switch 28.
Make it. Next, put a filter inside chamber 7.

Coffee beans are put in and the first cover 5 is slidably attached. After the water has boiled, press the start switch 30 and the solenoid valve 17
is driven, the hot water continues to flow out for about 180 seconds, and the hot water dispersed by the scattering plate 6 in the chamber 7 is stored in the container 8 from the dripping lower a after extracting coffee.

Next, when making Japanese tea or black tea, the hot water tap 20 is used. That is, when the first rotating shaft 20& is rotated, hot water in the hot water supply tank 11 passes from the hot water supply pipe 15 through the first connection pipe 22, and is stored in the container 8 from the first valve body 20b. With the hot water in this container 8, Japanese tea or black tea can be made using tea bags.

As shown in Figure 2, even if the hot water is used up for coffee extraction,
Also, even if the hot water is used up during hot water supply (the hot water supply pipe 15 is
1a) There is no hot water remaining in the cylindrical part 11a,
Empty heating of the heater 12 can be prevented. Hot water tank 1
In order to completely drain the hot water in the cylindrical part 11a, use the drain plug 21'' and rotate the second rotating shaft 21?L to drain the hot water in the cylindrical part 11a to the drain pipe 16. 23
The remaining hot water can be stored in the container 8 from the second valve body 21b. In this case, since the volume of the remaining water portion 11a is designed to be smaller than the volume of the decanter 8, the remaining water in the cylindrical portion 11a can be disposed of by using the container 8 only once. Furthermore, even if a large amount of hot water remains in the hot water tank 11, it can be easily drained using the container 8 without having to move the main body of the device.

Next, heater 12. Thermostat 13. If a component such as the temperature fuse 14 is broken and needs to be replaced, the hook 10a of the second cover 10 is removed using its elasticity, thereby exposing the faulty part. For this reason, the hot water supply valve 20. Parts such as the drain valve 21 can be easily replaced from the front.

Effects of the Invention As is clear from the above explanation, according to the present invention, the cylindrical part of the hot water supply tank and the chamber are arranged in parallel, so the overall size is reduced, and the drain port is formed in the cylindrical part, so the hot water supply The tank can be easily drained.
