空気漏れをおこすという問題があつた。 Incidentally, the upper end opening of the container is closed with a metal inner lid to prevent the lower surface of the lid from being directly thermally damaged by the heat generated by the steam inside the container. However, since the inner lid is simply placed on the top of the container, it has the drawback of requiring the effort of opening the lid and removing the inner lid twice when refilling the container with water. . Additionally, if the inner lid is not placed accurately on the top of the container, liquid may leak from between the container and the inner lid if the air pot is accidentally tipped over, or air may leak when the air pump is operated. There was a problem.

It is stored. A band heater 4, which is an example of an electric heater, is wrapped around the outer periphery of the bottom of the container 3, and one opening 5 is bored in the bottom surface of the container 3. One end of a connecting pipe 6 is welded to this opening hole 5, and a water supply pipe 8 and a water level pipe 11 are connected to the other end of the connecting pipe 6 via a branch pipe 7. The upper end of the water supply pipe 8 is connected to a spout 10 via a safety valve 9, while the upper end of the water level pipe 11 communicates with the upper part of the container 3. The water level tube 11 is made of a transparent material such as glass, and the water level inside the water level tube 11 can be visually observed through a display window (not shown).

4 can be opened and closed freely, and an air pump 16 that can be expanded and contracted by the pressing operation of a pusher body 15 is housed inside the lid body 14. This air pump 16
is attached to the lid 14 by fitting its lower end claw portion 16a into the center through hole 14a of the lid 14, and the air supply port 16b of the air pump 16 faces the center of the bottom surface of the lid 14. . This air outlet 1
An annular sealing rubber 17 is attached to the inside of the sealing rubber 17, and the outer periphery of a bowl-shaped portion 17a integrally provided at the lower part of the sealing rubber 17 is held by an annular wall 14b vertically provided on the lower surface of the lid 14.

体に取付けられる。 Reference numeral 18 denotes a metal inner lid that closes the upper end opening of the container 3, and a seal packing 19 that tightly contacts the upper end surface of the container 3 is attached to the outer periphery of the inner lid. An air pipe 20 is erected in the center of the inner lid 18.
A bulging portion 20a is formed on the outer periphery of the upper end of the air pipe 20. When the air pipe 20 is inserted into the center hole 17b of the seal rubber 17 from below, the air pipe 20 is forced into the center hole 17b because the outer diameter of the bulged portion 20a is slightly larger than the inner diameter of the center hole 17b. The bulging portion 20a protrudes toward the upper surface of the central hole 17b, thereby being prevented from coming off downward.
As a result, the inner lid 18 is integrally attached to the lower surface of the lid body 14.

の空気漏れも防止される。 In the electric air pot with the above configuration, the inner lid 1
8 to the lid body 14, attach the inner lid 18 to the container 3.
By placing the air pipe 20 in the upper end opening and closing the lid 14, the air pipe 20 is inserted into the center hole 17 of the seal rubber 17.
It is easy to install because it automatically fits into the b. When the lid body 14 is closed, the outer circumferential seal packing 19 of the inner lid 18 is pressed against the upper end of the container 3, so that the inner lid 18 is pressed against the lower surface of the lid body 14 by the reaction force, and the bowl of the seal rubber 17 is pressed. The shaped portion 17a is pressed and bent and press-fitted to the upper surface of the inner lid 18. Therefore, the air from the air pump 16 flows between the outer surface of the air pipe 20 and the center hole 17b of the seal rubber 17.
It does not leak to the outside through the gap between the inner surface and the inner surface. At the same time, the lower surface of the outer periphery of the lid body 14 is
Since it is press-fitted to the upper surface of the seal packing 19 attached to the outer circumference of the container 8, air leakage from the gap between the inner lid 18 and the container 3 is also prevented.
なお、中蓋１８に水垢などが付着した場合に

ことができる。 In addition, if limescale or the like adheres to the inner lid 18, if the inner lid 18 is forcibly pulled out from the lid body 14, the air pipe 20 can be inserted into the center hole 17b of the seal rubber 17.
Since it can be easily removed from the inner lid 18, only the inner lid 18 can be cleaned.

給電を停止させることができる。 Next, the operation of the electric air pot will be explained. First, when the air pump 16 is compressed, the pressurized air is sent into the container 3 through the air pipe 20 of the inner lid 18 fitted into the center hole 17b of the seal rubber 17, and the air pressure inside the container 3 is Liquid is supplied to the outside via a connecting pipe 6 and a water supply pipe 8. Now, if you continue to operate the air pump 16, the hot water in the container 3 will decrease, and when it decreases to a certain level, the air that entered through the upper end communication hole 11a of the water level pipe 11 will pass through the branch pipe 7 and enter the water supply pipe. 8
Therefore, hot water will not be discharged even if the air pump 16 is operated. This level, that is, the residual water position L is at the same level as the installation position of the branch pipe 7, and is located at an intermediate position between the upper end surface and the lower end surface of the band heater 4. Therefore, even if the air pump 16 is operated too much, a certain amount of hot water will always remain, so the temperature controller 23
There is no fear that the temperature of the container 3 will rise rapidly in the event of a failure, and a temperature fuse (not shown) attached to the outer surface of the container 3 can be activated to stop the power supply before the resin parts are damaged by heat.
なお、電熱ヒータとしては上記実施例のような

よい。 Note that the electric heater is not limited to the band heater 4 wrapped around the bottom outer periphery of the container 3 as in the above embodiment, but may also be a thermistor or the like attached to the bottom surface of the container 3.

る。 FIG. 4 shows a second embodiment of the present invention, in which a resin knob member 25 is fixed to the central step 18a of the inner lid 18, and an air supply pipe 20 erected on the knob member is connected to a rubber seal 17. The air sent from the air pump 16 to the air pipe 20 flows into the container 3 through the air hole 18b of the inner lid 18. In this case, the air pipe 20
Since it is integrally molded with the knob member 25, troublesome processing such as welding the air pipe 20 is not necessary.

それがない。(f) Effects of the invention As described above, according to the invention, an air supply pipe is installed upright in the center of the inner lid, and a seal rubber is attached to the air supply port of the air pump facing the center of the bottom surface of the lid. By fitting the air pipe into the center hole of this seal rubber, the inner lid is attached to the bottom surface of the lid, so when the lid is opened, the inner lid can be opened at the same time, and when replenishing water into the container, Very convenient. Furthermore, if the inner lid becomes dirty with limescale or the like, the inner lid can be easily removed from the lid body by forcibly pulling it out, so that the inner lid itself can be cleaned. Furthermore, since the air supply pipe is fitted into the center hole of the seal rubber, the high temperature steam inside the container is not directly applied to the seal rubber, thereby improving the durability of the seal rubber. Furthermore, since the inner lid is attached to the center of the lower surface of the lid, when the lid is closed, the inner lid is in close contact with the upper surface of the container, and there is no risk of liquid or air leakage.
