Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a so-called airbot that dispenses liquid in a pot by forcing air into the pot using a bellows.

Structure of the conventional example and its problems As shown in FIG. 2, in the conventional airbot of this type, the lid body 1 that houses the bellows 2 is provided with a pusher body 4 at the center of its upper part, and a spiral coil inside the bellows 2 is provided. A spring 5 is provided in the upper opening 2a of the bellows 2.
is pressing.

Therefore, a gap 2' is normally provided between the two-part opening 2a of the bellows 2 and the seal ring 6 of the check valve 3. communicated with the outside.

On the other hand, in this type of pot, it is desirable that the water contained in the container be boiled for a certain period of time using a heater, and then kept at a temperature appropriate for the purpose.

However, in the above configuration, the steam generated from the hot water must pass through the communication path in the bellows to the outside as described above, and at that time, the bellows may suffer heat loss due to the high temperature steam, or the pushing body may become hot. It had the disadvantage of causing burns during operation.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides an airbot that can reliably drain steam generated from hot water in a container to the outside without going through a bellows or pusher.

Structure of the Invention The present invention comprises a container that stores a liquid and is equipped with a heating element at the bottom thereof, a bellows that introduces air into the container, a pouring pipe that pours out the liquid, and a container that connects the inside and outside of the container. It will be explained that the desired purpose is achieved by a configuration in which a communicating ventilation path and a flow path control means that is moved to open and close in response to the operation of the bellows are provided in the ventilation path.

In the case of meat, 11 is a lid body, and a main body 12 that houses the container 9.
It is pivotally connected to a pivot 13 provided at the rear of the bellows 14, and a bellows 14 is housed inside.

A cylindrical portion 1 whose top surface is open is located at the center of the upper part of the lid body 11.
A push plate 16 having a diameter slightly smaller than the inner diameter of the circular 151 part 15 is inserted into the cylindrical part 15, and the bellows 1 is inserted into the cylindrical part 15.
A compression spring 17 installed in 4 allows vertical sliding. Reference numeral 18 denotes a ventilation passage branched in the middle of an air passage 19 that communicates the opening 14b, which is an air outlet of the bellows r14, with the inside of the container 9. through which it communicates with the outside air. Reference numeral 20 denotes a control valve provided at a branch point between the air passage 19 and the ventilation passage 18, which normally closes the air passage 19 that communicates the opening 14b of the bellows 14 with the inside of the container 9, and as a result, the ventilation passage 18 is open to the inside of the container 9, and the inside of the container 9 is communicated with the outside air via a ventilation path 18. When the push plate 16 is pressed, the control valve 20 is slid by the air pressure ejected from the opening 14b of the bellows 14 to open the air passage 19 and close the ventilation passage 18, thereby closing the lower opening 14a of the bellows 14.
Compressed air blown out from the container 9 flows into the container 9. 2
A check valve provided in an opening 14a at the top of the single bellows 14 closes when the bellows 14 is compressed by the pusher 16, and opens when the bellows 14 returns to suck air into the bellows 14.

22 is an inner lid which has a through hole 22a and an air hole 22b in the center and a container backing 23 around it, and a lid backing 24 is interposed between it and the lid body 11. Reference numeral 27 denotes an overflow prevention valve seat interposed at the connection point between the water rising pipe 25 extending and opening at the bottom of the container 9 and the water injection pipe 26 extending outside the container 9 and opening externally; Reference numeral 28 indicates an overflow prevention valve; 29 indicates a band-shaped heater attached to the side surface of the bottom of the container 9; 30 indicates a heater 30 provided on the bottom back surface of the container 9; the water 31 in the container 9 is controlled to a predetermined level by controlling the energization of the heater 29; The figure shows a temperature controller that adjusts the temperature to .

In the above configuration, the liquid 31 contained in the container 9 is heated by the heater 29 and heated to 100° C. by the temperature controller 30.
It becomes boiling water.

At this time, the liquid 31 is heated by the heater 29, and a large amount of water vapor generated flows out through the opening 18' through the air hole 22b1, the through hole 22a1, the lid banking 24, and the air passage 18.

Next, when pouring out the hot water 31 in the container 9, pusher 16
When the bellows 14 is compressed by pressing the
Compressed air is ejected from b, and the ejected force slides the control valve 20 to open the air passage 19 in the container 9, and the air passage 18 is closed, allowing air to flow from the bellows 14 through the through hole 22a and the air hole 22b. Air is forced into the container 9 to increase the pressure inside the container 9, and this pressure causes the hot water 31 to be poured out from the water injection pipe 26 through the water riser pipe 25 and the overflow prevention valve seat 27.

Furthermore, in this embodiment, the heated hot water 31 has a heat-retaining function to be appropriately heated by the heater 29 so as not to cool down over time. Therefore, when keeping warm, boiling water
The amount of steam generated from 1 is much larger than in a pot used only for storage, such as a conventional magic bottle, but this steam flows through the ventilation passage 18 without entering the bellows 14, just as in the case of boiling described above. After that, it flows out to the outside.

As described above, according to this embodiment, the air passage 19 communicates the air outlet opening 14b of the bellows 14 with the inside of the container 9.
An air passage 18 is provided which branches off in the middle and communicates the outside air, and the air passage 19 is normally closed at this branch part, and the bellows 14 is closed.
By providing a control valve 20 that opens the air passage 19 and closes the ventilation passage 18 with the jet force of compressed air during the suppression operation, the water vapor generated by boiling of the heated liquid 31 can be easily removed. This makes it possible to reliably flow out to the outside via the push plate 16.

Even when the liquid 31 is still kept warm, it is similarly allowed to flow out through the ventilation path 18, and as in the conventional case, the steam generated from the liquid condenses on the inner wall of the bellows, causing the liquid 31, 11, and
When the container is closed, water droplets come off and fall, staining the floor, and over a long period of time, it becomes dirty water that contains dust in the air and drips into the container, causing discomfort. be.

In this embodiment, the air passage that communicates with the outside is provided by branching in the middle of the air passage that communicates the opening of the air outlet of the bellows with the inside of the container, and furthermore, the air passage that communicates with the outside is provided in the middle of the air passage that communicates with the inside of the container. Although the explanation has been provided with a control valve that opens the air passage by force and closes the air passage at the same time, this ventilation passage is not limited to being provided as a branch of the air passage. may be provided. The external opening of the ventilation path is not limited to the lid, but can be any structure that communicates the inside of the container with the outside of the main body.In addition, the control valve is not limited to one that is operated by the jet force of compressed air from the bellows. Any device may be used as long as it opens and closes the ventilation passage in conjunction with the operation.

Effects of the Invention As described above, the present invention provides a container containing a liquid and equipped with a heating element at its bottom, a bellows for introducing air into the container, a pouring pipe for pouring out the liquid, and a container. By providing a ventilation path that communicates the inside with the outside of the main body, and a flow path control means that opens and closes in conjunction with the bellows operation in this ventilation path,
The vapor generated from the liquid can reliably flow out to the outside through the ventilation passage, and damage such as heat loss to the bellows caused by the vapor can be eliminated, which is of great value.
