Description

[Detailed Description of the Invention] This invention relates to an air-equipped water boiler pot that boils water in a tank equipped with a heater and flows out the hot water from a spout using compressed air from a bellows.

In this type of pot, it is normal to raise the temperature of the water stored in the tank to about 90-95°C via a heater, and then keep the water warm with a 30-50W heater. However, when it comes to hot water for tea strainers, etc., it is said that it is preferable to boil the water and then cool it to around 70°C before using it. However, in such a case, a large amount of steam will be generated in the tank, and the problem of disposing of this steam will arise.

Conventionally, steam is generated when hot water is kept at a temperature of 90 to 95° C., so the steam is released to the outside through a bellows communicating with the tank.

In this case, there is no particular problem because the amount of steam is small, but when the water is boiled as described above, a large amount of steam is generated and the high temperature steam fills the bellows, resulting in the bellows being closed. There is a risk that the heat will cause premature deterioration.

This idea was developed with this in mind, and its purpose was to enable the steam generated in the tank to be accurately and safely discharged to the outside without passing through the bellows. They provide an air-conditioned kettle.

Note that 47 is a locking mechanism for locking the upper i15 to the end plate 2, and 48 is a lever for releasing the locking mechanism.

In addition, 49 is a liquid level gauge that displays the liquid level in tank 3;
0 is the viewing window.

According to such a configuration, the steam generated in the tank 3 sequentially passes through the flow passage 13, the inlet 11, the steam passage 10, the outlet 12, the guide tube 37, and is discharged to the outside from the steam holes 38. Therefore, the pressure inside the tank 3 does not become abnormally high.

When the pushing body 21 is pressed downward in this state, the first spring 33 is compressed, and this compression moves the opening/closing body 29 downward, and the opening/closing plate 31 moves toward the backing 30.
This abuts against the inlet 11 via the inlet 11, thereby closing the inlet 11 and opening the ventilation holes 32.

Further, as the pushing body 21 descends, the closing portion 25 of the closing body 23 abuts against the backing 27 of the through hole 26, and the inside of the bellows 19 is sealed, and the movable plate 18 is pressed downward, thereby causing the bellows to close. 19 and the air inside it is compressed.

The compressed air then flows through the ventilation holes 32... and the flow path 1.
3 into the tank 3, and the liquid level of the hot water is pressurized.

Due to this pressurization, a part of the hot water in the tank 3 is led out from the spout 44 through the hot water pipe 46 and the hot water path 43.

After that, when the pressure on the pusher body 21 is released, the pusher body 21 rises due to the elastic force of the third spring 35, and accordingly, the opening/closing body 29 rises due to the elastic force of the second spring 34, and the closing portion 25 is separated from the backing 27 and the through hole 26
External air flows into the bellows 19 through the bellows 19, and as the air flows in, the movable plate 18 is raised by the elastic force of the fourth spring 36, and the bellows 19 is restored to its initial state.

By repeating these operations, the hot water in the tank 3 can be taken out in appropriate amounts.

The inside of the tank 3 communicates with the outside through a steam escape path 51, but when the bellows 19 performs a compression operation, the steam escape path 10 is closed by the opening/closing plate 31 of the opening/closing body 29, and communication between the inside of the tank 3 and the outside is interrupted. Since the state is blocked, bellows 1
Ensure that the compressed air in tank 3 does not leak to the outside.
It can be introduced inside.

In normal times, the steam in the tank 3 is discharged to the outside through a separate steam escape path 51 without passing through the bellows 19, which has the advantage that there is no risk of the bellows 19 being deteriorated by the heat of the steam. There is.

In addition, since the steam is always discharged from a fixed position via the steam vents 38, and the user of the pot can know in advance the discharge point, it is possible to inadvertently touch the steam and get burns. It can be used safely without any risk of injury.

As explained above, according to this invention, the steam generated in the tank is discharged to a fixed position outside the pot via the steam escape path without passing through the bellows, which ensures that the bellows does not deteriorate. This has the effect that it can be prevented and can be used safely.
