Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air pot which uses an air pump such as a bellows or an electric pump to forcefully send air into a container containing a liquid to pour out the liquid in the container. It is something.

4. Prior Art In this type of conventional air pot, as shown in the figure, a bellows (not shown) housed in the lid body 1o1 is pressed by a pressing member 102, or a switch of an electric pump is turned on. The liquid in the container is poured out by pressurizing air into the container. Although not shown, there is also a device in which the spout is movable and can be stored in the vessel, and the spout is pulled out of the vessel when hot water is poured out.

Problems to be Solved by the Invention In the case shown in FIG.
When you press 2 or operate the electric pump switch,
Since hot water is poured out, there is a danger of getting burned by the hot water, so the pressing of the suppressor must be controlled by operating the lock lever 103 to prevent the boiling water in the container from being poured out due to malfunction. In addition, if the spout is movable and can be stored inside the container, if you accidentally press the suppressor and pour out hot water when storing the spout, there is a risk of burns and the boiling water will leak into the container. This can contaminate the inside of the container, cause rust, and cause electrical failure.

For this reason, when the discharge port is housed inside the container, it is necessary to prevent the liquid in the container from being poured out.

In view of the above-mentioned conventional drawbacks, the present invention has a spout that makes it impossible to pour out the liquid in the container when it is housed inside the container, and allows liquid to be poured out only when it is outside the container. This provides an air-type pot that can be used.

Means for Solving the Problems To this end, the present invention provides an air pump that pumps air into a container containing a liquid and pours out the liquid in the container.
The air pump is provided with a series of passages communicating between the inside of the container and the outside air, and an auxiliary passage between the air pump and the outside air, a movable valve is provided in the auxiliary passage, and the movable valve is used to pour out the liquid to the outside. With this configuration, when the spout is housed in the container, the movable valve opens and closes in conjunction with the movement of the movable spout. Even if the pressing body is pressed, the air inside the air pump escapes to the outside through the passage of the movable valve part, and the air is not forced into the container, so that incorrect dispensing of liquid is prevented. Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3. In the figure, 1 is a bottomed cylindrical container made of stainless steel plate, etc. At the bottom of this container, there is a planar main heater insulated with an insulating plate such as mica and seamed with an aluminum plate, iron plate, etc. -2 and auxiliary heater 3

Further, on the back side of the bottom end of the container 1, a heat-retaining temperature regulator 5 and a temperature overrise prevention device 6 are thermally attached to the container. The flange portion 7 is an extended flange portion, and is attached to the spout 9 through a container backing 8 in a watertight manner. 1o is the outer shell of the container.

Reference numeral 11 denotes an inner lid detachably provided on the upper part of the container 1. The inner lid 11 has a steam hole 12 at the upper center and a valve chamber 14 containing a central overturning and outflow prevention valve 13. Further, the inner lid 11 is held airtight with the container 1 by a waterproof backing 16 provided on its outer periphery.

Reference numeral 16 denotes a water raising vibrator led out from the bottom of the container 1, and communicates with the spout 18 through a valve chamber 17 containing an overflow prevention valve. The spout 18 and the valve chamber 17 are connected by a water injection pipe 40, and hot water enters the spout 18 through a water inlet 41 provided in a part of the water injection pipe 40. Further, the spout 18 rotates around the water injection pipe 4o, and is housed in an outer shell recess 10a provided in a part of the outer shell 10 of the container, or comes out of the container. There is a water inlet 18b near the tip, and hot water is supplied to the outside of the vessel. Reference numeral 2o denotes an upper lid pivotally mounted on the spout 9 so that it can be opened and closed;
The back part 20a is used as a fulcrum, and the front beak part 2ob is configured to be opened and closed by locking knobs 21 provided on both sides thereof. A cylindrical portion 22 with an open top is provided in the center of the upper lid 20, and a push plate 23 that is vertically slidable is provided inside the cylindrical portion 22. Reference numeral 24 denotes a lock ring that restricts the vertical sliding of the push plate 23, and this lock ring 24 engages with a switching lever 25 so that the vertical movement of the push plate 23 can be selected.

Reference numeral 26 denotes a bellows pump provided at the lower part of the push plate 23, and the upper surface of this bellows pump is fixed to the upper plate 27, and the lower surface is fixed to the lid cover 28 by ultrasonic welding or the like, so that the bellows pump is sealed.

Further, the upper plate 27 has a vent hole 27a in the center thereof, which is provided at the center of the steam cover 29 which is integrally engaged with the push plate 23 when the push plate 23 moves downward. It is closed at the lower end of the push lip 29a, and the push plate 23
Movable valve B3 that can open the vent 27a when the
