Description

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

Conventional structure and its problems Conventionally, in coffee makers of the hot water storage drop type, a cylindrical part was provided at the bottom of the hot water storage tank in order to prevent dry cooking and improve productivity.
A configuration in which a space heater is wound and fixed in a band shape around the cylindrical portion has been 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 has the advantage of preventing the heater from running dry. . 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. . In addition, in the hot water storage push-up type coffee maker, the hot water boiling 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 pump up and discharge the hot water, and when draining water, the drain port is located low from the floor, so the coffee maker itself This has the disadvantage that it is necessary to move the container and receive the container at a position lower than the drain. Furthermore, not only was there a problem of stains caused by scattered coffee when brewing coffee, but also serviceability when a solenoid valve was provided at the outlet.

OBJECTS OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned conventional drawbacks. In other words, the overall size is compact and has the function of preventing dry cooking, and the solenoid valve, which is a functional part, can be easily replaced. The purpose is to provide a coffee machine that can easily clean the ceiling above the chamber.

Structure of the Invention The present invention provides a main body, a hot water supply tank provided in the main body and having a cylindrical part at the lower part of one side, a thermostat and a heater installed in the cylindrical part, and a hot water supply tank provided at the lower part of the other side of the water supply tank. A solenoid valve provided, a cover provided below the solenoid valve,
The device includes a scattering plate provided below the cover and a chamber provided below the scattering plate, the scattering plate and the chamber being detachable from the cover, and the cover being detachable from the main body. .

, 1e, and can be easily attached and detached without using metal fittings such as screws. Reference numeral 11 denotes a hot water tank, which has a cylindrical portion 111L for residual water on one side of the bottom surface, and a heater 12 is fixed to the outer periphery of the cylindrical portion 111L. or,
On the bottom surface of the cylindrical portion 111L, there is a thermostat 13. A temperature fuse 14 for preventing abnormal temperature rise is fixed with screws or the like, and a hot water supply pipe 16 and a drain pipe 16 are each fixed by welding. The hot water supply pipe 15 is configured to protrude into the cylindrical portion 111L. Reference numeral 17 is a solenoid valve provided on the bottom of the hot water tank 11, and is fixed to the hot water supply 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 front plate 1& with screws. 20 is a hot water tap, which is composed of a rotating shaft 2oa and a valve body 20b,
The threaded part rotates to open and close the valve. 21 is a drain plug, which includes a valve body 21b, an O-ring 210, and a valve seat 21 (i
The rotating shaft 21a and the valve body 21b are rotated by a threaded portion to open and close the valve. 22 is a connecting pipe that communicates the hot water supply pipe 16 and the hot water tap 20, and 23 is a connecting pipe that communicates the drain pipe 16 and the drain valve 21. 24 is a leg fixed to the bottom plate 4. 25 is a lid for water supply, and a lid backing 26 is attached thereto.

2T is a tank backing for keeping the outer panel 2 and the hot water tank 11 airtight. 28 is a power switch; 29
is the switch of Warmer 9.

30 is a start switch when brewing coffee, and in operation, the solenoid valve is energized for about 180 seconds using a timer function, and an amount of hot water of about 15,000 c can be discharged. 31 is a stop switch used when the start switch is pressed by mistake and the extraction is stopped.

In the above configuration, the operation will be explained.

First, open the lid 26, supply water, and turn on the power switch 28.
Make it. Next, a filter and coffee beans are put into the chamber 7 and are slid and fixed to the cover 6. When the start switch 30 is pressed after the water has boiled, the solenoid valve 1 is activated and the scattering plate 6 in the chamber 7 is heated for approximately 180 seconds.
After the coffee is extracted, the hot water dispersed in the hot water is stored in the decanter 8 through the dripping port 1a.

Next, when making Japanese tea or black tea, use a 2° hot water tap. That is, when the rotating shaft 201L is rotated, the hot water in the hot water supply tank 11 is transferred from the hot water supply pipe 15 to the connection pipe 2.
2 and is stored in the decanter 8 from the valve body 20b. Japanese tea and black tea are made using the hot water in this carafe 8 using cucumbers and tea bags.

As shown in FIG. 2, even if the hot water in the hot water tank 11 is used up for coffee brewing or hot water supply, the hot water pipe 16 protrudes into the cylindrical portion 112L and hot water remains in the cylindrical portion 111L. , it is possible to prevent the heater 12 from running dry. In order to completely drain the hot water in the hot water tank 11,
By using the drain plug 21 and rotating the rotating shaft 21&, the hot water in the cylindrical portion 111L is drained from the drain pipe 16. Remaining hot water can be stored in the decanter 8 from the valve body 21b via the connecting pipe 23. In this case, the volume of the residual water portion 112L is designed to be smaller than the volume of the decanter 8;
The remaining water in the cylindrical portion 111L can be disposed of by using the decanter 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 a decanter without having to move the main body of the device.

Next, cleaning of the parts around the chamber 7, which is the most dirty part of the entire coffee maker, will be explained. Inside chamber 7 is a filter.

When coffee beans, etc. are put in and the shower-like hot water dispersed by the scattering plate 6 is sprinkled over the coffee beans, the splashing of the hot water causes coffee liquid and coffee bean scum to be deposited on the scattering plate 6 and the cover 6. etc. are attached. For this reason, in this embodiment, the cover 6 fixing the scattering plate 6 of the chamber 7j has a structure that can be easily attached and detached without tools by tightening the fixing screw 51L with a knob to the front plate 1a, so that it can be cleaned by washing. It has become. In addition, since the cover 6 can be easily removed, the solenoid valve 1, which is a functional component, can be easily removed.
This also has the effect of making it easier to exchange tickets and improving serviceability. In this embodiment, the cover 6 is attached using a fixing screw with a knob, but it can also be attached by using a hook part and a projection part and fixing it using the elasticity of the material, like the method of attaching the cover 10. Similar effects can be expected.

Effects of the Invention As explained above, the present invention not only has the function of preventing dry cooking, and also makes it possible to easily replace the solenoid valve, which is a functional part, but also removes the parts near the chamber and scattering plate, which are the parts that are most likely to get dirty. It is possible to provide a coffee maker which has the effect that the components thereof can be easily attached and detached and can be easily cleaned.

Note that the cover 5 in the above embodiment. If the cover 10 is integrally molded, it is possible to further reduce costs and improve serviceability.
