Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drip-type co-heater.

[0002]

2. Description of the Related Art As a conventional example, for example, Japanese Utility Model Publication No. 62-13
As disclosed in Japanese Patent No. 556, water for a desired number of people is first put in a decanter and then put in a water tank again, or
Alternatively, it has been a troublesome work to remove the water tank from the main body, directly put water in the main body, and then return the water tank to the main body.

[0003]

SUMMARY OF THE INVENTION The present invention has been conceived in consideration of the above points, and an object thereof is to provide a co-heater which is extremely convenient to use.

[0004]

According to the present invention, a water tank heated by a heater is provided inside the main body and a mounting surface is formed on the upper surface, and the water tank is externally connected via a check valve. A pipe exposed to the above is provided, a decanter having an upper surface opening is attached to and detached from the mounting surface, and a chamber facing the opening of the pipe is attached to and detached from the upper surface opening of the decanter. The bottom surface portion and the upper surface portion of the water tank are connected by a connection of a normally closed first communication valve and a normally closed second communication valve, and the decanter is placed on the mounting surface and the first communication valve and the first communication valve are connected to each other. When the two communication valves are connected, both valves are opened so that the decanter and the water tank communicate with each other, and the both valves are closed after a predetermined time or a predetermined temperature elapses.

[0005]

In other words, simply put a desired amount of water in the decanter, place it on the mounting surface of the main body, and connect the first communication valve and the second communication valve, and the water in the decanter will automatically It is supplied to the water tank inside the body.

[0006]

Embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a main body of a co-heater, and a water tank 3 which is heated by an electric heater-2 is provided therein. The water tank 3 is provided with a second communication valve 4 that communicates with the outside of the main body 1. A pipe 6 is connected to the bottom of the water tank 3 via a check valve (not shown). The pipe 6 is erected outside the main body 1.

Reference numeral 7 is a decanter which is attached to and detached from a mounting surface formed on the upper surface of the main body 1, and which is provided with a first communication valve 8 connected to the second communication valve 4 and a skirt 9 on the outer periphery of the bottom. The lever 1st communication valve 8 is protected.

Reference numeral 10 denotes a chamber provided in the upper opening of the decanter 7, which is provided with a paper filter 11 for containing coffee powder therein and which opposes the opening of the pipe 6. I have to.

The first communication valve 8 comprises a lid portion 50, a first opening / closing valve 13 which is constantly pressed by the first spring 30, and a packing 51. The flange portion 15 formed on the first opening / closing valve 13 is separated from the inner bottom portion of the decanter 7 to form the first passage 16 when the protruding portion 52 is pushed up from below, and normally forms the first passage 16 as shown in FIG. 1 spring 30
The first passage 16 is pressed against the inner bottom portion of the decanter 7 to close the first passage 16.

The second connecting valve 4 has a cylindrical portion 55, a second opening / closing valve 21 which is H-shaped forming the second passage 24 and is pushed down by the urging force of the second spring 23, and is normally bent upward. The shape-changing member 20 that changes from the upper curve to a substantially horizontal straight line after a predetermined temperature or a predetermined time elapses, and the base 60.
It is composed of.

This second on-off valve 21 is constantly pushed down by the urging force of the second spring 23, and as shown in FIG.
4 is closed by the cylindrical portion 55.

The operation of this structure will be described below.
As shown in FIG. 4, the first opening / closing valve 13 of the first communication valve 8 is the first
With the passage 16 closed, water is supplied into the decanter 7, and then the decanter 7 is placed on the placement surface of the main body 1 as shown in FIG. At this time, the variable shape member 20 is bent upward as shown in FIG. 5, and the second opening / closing valve 21 is pushed down by the urging force of the second spring 23, and the second opening / closing valve 21 is also moved to the second shape as shown in FIG.
Although the passage 24 is closed by the cylindrical portion 55, when the decanter 7 is placed on the placing surface of the main body 1 as described above, the cylindrical portion 55 is pushed downward by the packing 51 and the second passage 2
4 is opened and the first opening / closing valve 13 is opened by the second opening / closing valve 2
1, the first passage 16 is pushed up at the upper part of the first passage 24
It is opened to communicate with.

Therefore, the water in the decanter 7 is supplied into the water tank 3 through the first passage 16 and the second passage 24.

When the shape-variable member 20 is cooled to a predetermined temperature with the supplied water, it becomes horizontal as shown in FIG. 2, and the second opening / closing valve 21 and the first opening / closing valve 13 are provided with springs 23, 30. It is pushed down by the force to close the first passage 16 and the second passage 24.

After that, hot water is generated by the well-known drip method and is supplied from the pipe 6 to the coffee powder in the chamber 10.

[0017]

EFFECTS OF THE INVENTION Since the present invention has the above construction, it is not necessary to supply water into the water tank as in the conventional case, and water for a desired number of people is put in the decanter and placed on the main body. Water is automatically supplied to the water tank just by placing it.

Claims (1)

[Claims] 1. A water tank heated by a heater is provided inside the main body, and a mounting surface is formed on the upper surface, and a pipe exposed to the outside through a check valve is provided in the water tank. A decanter having an upper surface opening is attached to and detached from the placing surface, and a chamber facing the opening portion of the pipe is attached to and detached from the upper surface opening of the decanter, and the bottom portion of the decanter and the upper surface of the water tank are attached. When the first communication valve and the second communication valve are connected by connecting the normally closed first communication valve and the normally closed second communication valve, and the decanter is placed on the mounting surface described above, the first communication valve and the second communication valve are connected. In addition, the co-heater is characterized in that both valves are opened so that the decanter and the water tank are communicated with each other and the both valves are closed after a lapse of a predetermined time or a predetermined temperature.
