The valve device 3a' and the valve seat 3d may be of the known type used, for example, for refueling kerosene heaters, and are not particularly new, so a detailed description thereof will be omitted here.

The water storage section 3 and the heating chamber 2a of the heating section 2 are connected by a water supply pipe system 4, and the water supply pipe system 4 is composed of an electromagnetic valve 4a, a water supply pipe 4b, and an exhaust pipe 4c, such as an electric valve. ing.

The water supply pipe 4b is arranged to inject water from the water storage tank 3a into the lower part of the heating chamber 2a, and the electromagnetic valve 4a is provided to open and close the water supply pipe 4b.

Furthermore, the exhaust pipe 4c is for discharging the atmosphere in the water supply pipe 4b, and is configured to communicate with the water supply pipe 4b at a position below the solenoid valve 4a, and has an exhaust port located above this communication point. It is made.

In the embodiment, the water supply port side of the water supply pipe 4b is connected to the valve seat 3d, and is communicated with the water storage tank 3a via the valve seat 3d.
Further, the exhaust port 4c' of the exhaust pipe 4c communicates with an exhaust pipe system 5 extending from the ceiling of the heating chamber 2a.

The exhaust pipe system 5 is for discharging the atmosphere inside the heating chamber 2a, and in the embodiment has an exhaust pipe 5a standing upright in a water injection chamber 6 arranged in parallel with the water storage section 3.

A water injection pipe 7 is installed between the water injection chamber 6 and the heating chamber 2a, and the water injection pipe 7 has a water injection port 7a opened at the bottom of the water injection chamber 6, and a water supply port 7b opened at the bottom of the water injection chamber 6. The water inlet pipe 7 communicates with the lower part of the inside of the heating chamber 2a, and in the embodiment, the water injection pipe 7 projects from the ceiling of the heating chamber 2a into the room and is suspended therefrom.

The heating chamber 2a is provided with two hot water supply pipe systems, the first hot water supply pipe system 8 is connected to the top of the upper part of the heating chamber 2a, and the second hot water supply system 9 is connected to the first hot water supply pipe system 8. It communicates with the heating chamber 2a slightly below.

The first and second hot water supply pipe systems 8 and 9 are connected to the heating section 2.
It has hot water supply ports 8a and 9a on both sides, and usually the first
The hot water supply port 8a of the hot water supply pipe system is configured as a shower port, and a mounting portion for the dripper 10 is formed on the outside, and the hot water supply port 9a of the second hot water supply pipe system 9 is configured to open at the outer edge of the apparatus exterior body. In addition, the valve is configured to be opened and closed by a solenoid valve 9b, which is an example of an electric type valve.

An operating circuit 11 is provided for the solenoid valve 4a of the water supply pipe system 4 and the solenoid valve 9b of the second water supply pipe system 9, and this operating circuit 11 is provided with two external operation switches 11a and 11b. There is.

Among the above switches, the first switch 11a opens the two electromagnetic valves 4a and 9b at the same time when operated, whereby the water in the water storage tank 3a is supplied to the lower part of the heating chamber 2a and heated. The hot water in the upper part of the chamber 2a passes through the second hot water supply pipe system 9 and is discharged from the hot water supply port 9a.

Among the above switches, the second switch 11b is connected to the solenoid valve 4a of the water supply pipe system 4 via the timer circuit 11c.
When operated, the solenoid valve 4a is opened for a certain period of time, for example, 160 seconds, and a relay circuit 11d is provided as required. Valve 9b is kept inactive.

Therefore, when the second switch 11b is operated,
The water in the water storage tank 3a is automatically heated to the heating chamber 2 for 160 seconds.
Therefore, the hot water in the heating chamber 2a is poured into the dripper 10 in the form of a shower from the hot water supply port 8a of the first hot water supply pipe system 8 during the set time.

The operating circuit 11 operates when both the solenoid valves 4 are operated.
a, 9b or the one-way solenoid valve 4a, the solenoid valves 4a, 9b are set to open when energized, and the temperature detection means 2d of the heating chamber 2a It is set to detect the water temperature in the lower part of the room.

In the above, the exhaust pipe system 5 and the first hot water supply pipe system 8 are similar to the conventional apparatus of this type.
The protrusion dimension of the heating chamber of the first hot water supply pipe system 8 is set to be shorter than the protrusion dimension of the heating chamber of the first hot water supply pipe system 8. Therefore, when the water level in the heating chamber decreases during hot water supply,
The exhaust pipe system 5 opens before the first hot water supply pipe system 8.

Since the proposed device is like this, the water injection chamber 6
Pour water into the tank, and add the same amount of boiling water as the injected amount to the first
In addition to being able to take out hot water from the hot water supply port 8a, it is also possible to obtain the desired amount of hot water from the second hot water supply port 9a by operating the first switch 11a. Hot water can also be obtained from the first hot water supply port 8a.

Therefore, using this device eliminates the need for pouring water when making coffee for a large number of people, and also has the advantage of being able to make beverages other than coffee since hot water can also be obtained from the second hot water supply port 9a. be.
