Description

[Detailed Description of the Invention] Industrial Application Field The present invention seals the opening of a water container, forces air into the water container using an air pump, and extracts hot water from the water container to the outside through a water extraction pipe. It is related to air pots.

BACKGROUND ART Conventionally, this type of air pot is equipped with a water container built into the body, communicates with the water container at the front lower part between the water container and the body, and has an overflow prevention valve at the upper part. A pipe was installed upright, and the hot water inside the water container was extracted to the outside through this extraction pipe. (For example, Publication of Utility Model Publication No. 59-37148) Problems to be Solved by the Invention In the configuration of such a conventional air pot, the overflow prevention valve works to prevent the contents from flowing out of the container when the container topples. However, in reality, a slight gap was created between the valve body and the outflow hole (valve seat), making complete waterproofing difficult.

Therefore, if you are not aware of the possibility of the vessel falling over,
The liquid contents continued to leak little by little, staining the floor and potentially causing burns to the baby sleeping nearby.

In addition, in those equipped with a heater, the container body is heated up, which shortens its lifespan.

The present invention is intended to solve these problems, and aims to provide an air pot equipped with a reliable and safe overturning and outflow prevention mechanism.

Means for Solving the Problems In order to solve the above problems, the present invention provides a water container housed in a body, a spout provided at the top of the water container, and a spout that covers the water container. an air pump having an air supply hole for pumping air inside, a lid body pivotally connected to the spout, and an extraction device that leads the liquid in the water container to the outside of the container by pumping air into the water container. The extraction pipe is connected to the lower part of the water container, and also includes a valve body extending upwardly along the outer wall of the water container and above the water level to prevent liquid from flowing out of the container when it falls over. The water container has a valve housing cylinder for housing the water container, and the air supply hole of the air pump is located closer to the valve housing cylinder than the center of the water container.

Effect With this configuration, when the container falls over, even if the valve housing cylinder is located on the bottom surface, the air pump's air supply hole will also be submerged in the liquid level, so the outside air and the inside of the water container will be cut off.
Even if there is a gap between the valve body and the valve seat in the valve storage cylinder, water is completely shut off, resulting in extremely high safety.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. In Figures 1 and 2, 1

A spout cover 3 is provided, a beak portion 2a projecting forward is integrally molded, and a hinge receiving portion 2b is integrally molded near the rear corner. Reference numeral 4 denotes a synthetic resin lid body attached to the upper part of the spout 2, and a hinge 4a having an engaging pin 5 that can be freely engaged with and detached from the hinge receiving part 2b is integrally molded at the rear corner of the lid body 4. Further, the lid body 4 is rotatable and detachable about the engagement pin 5 as a pivot point. Further, the front corner of the lid body 4 is locked to the spout 2 by a lock knob 6, so that the lid body 4 can be opened and closed freely.

Reference numeral 7 denotes an air pump for pumping air, and this air pump 7 consists of a bellows 7a, a check valve 7b, a pressing plate 7c, a bellows upper plate 7d, a lid cover 7e, a check valve spring 7f, a bellows spring 7g, and a seal packing. 8 through the flange 9a of the water container 9
The inside of the bellows 7a is communicated with the lid cover 7.
Air is forced into the water container 9 through the air supply hole 7h provided at e.

Numeral 10 is a lock member for clocking the air pump 7, and this lock member 10 is adapted to restrict vertical sliding of the press plate 7c. 11 is a handle, 12 is an electric heater, 13 and 14 are temperature regulators, 15 is a water level gauge, and 16 is a safety fuse.

Reference numeral 17 denotes a mounting bracket spot-welded to the bottom of the water container 9, and a base 18 located at the lower end of the body 1 and a back plate 19 are screwed to the mounting bracket 17.

Reference numeral 20 denotes an extraction pipe located at the beak 2a of the spout 2 and installed upright in the space between the body 1 and the water container 9. The lower end of this extraction pipe 20 is connected via a flexible connector 21 and an outflow pipe 22 and communicates with the inside of the water container 9.

Reference numeral 23 denotes a hollow truncated conical valve storage cylinder attached to the spout 2 in the vicinity of the beak 2a.
The lower inlet 23a is communicated with the extraction pipe 20, and the upper opening has an outlet hole 24 in the center.
A valve cover 24 having a diameter is provided.

Reference numeral 25 denotes a valve body in the shape of an inverted truncated cone, which is housed in the valve housing cylinder 23 so as to be vertically movable, and is made of ceramic. 23b is on the inner wall of the valve housing cylinder 23,
A plurality of guide pieces integrally molded in a radial shape, each having an inclined surface facing diagonally upward. When the container is overturned, the valve body 25 is guided by the inclined surface and moves toward the valve cover 24 to close the outflow hole 24a. 23c A conical flow divider plate provided approximately horizontally between the plurality of guide pieces 23a, and the flow divider plate 23c allows the valve body 25 to close the outlet hole when pressure of the liquid flowing out is applied to the lower end surface of the valve body 25. This is provided to prevent the block 24a from being blocked.

Furthermore, with the center line of the water container 9 as a reference,
The air supply hole 7h of the air pump 7 is eccentrically provided on the side of the valve storage cylinder 23 as shown in FIG.

26 communicates the tip of the valve cover 24 with the outlet 3a provided in the spout cover 3, and allows the water container 9 to flow out of the container.
This is a discharge pipe that extracts the liquid inside.

With the above configuration, the conventional overflow prevention valve could not completely stop water due to the small gap between the valve body and the outflow hole, but as shown in FIG. It can only fall in four directions on each side. Therefore, the valve storage cylinder 23 that houses the valve body 25 for preventing overturning and outflow is located above the water level in the direction of the sides 1c and 1d of the body 1, and the fluid does not flow out to the outside of the vessel. case sides 1a and 1
It is sufficient to target only the b direction.

Also, in the directions 1a and 1b, as shown in Fig. 5, the air supply hole 7h of the air pump 7 is submerged in the liquid level, so the outside air and the inside of the water container 9 are cut off and no outside air is taken in. Valve body 25 inside the cylinder
Even if there is a gap between the outflow hole 24a and the outflow hole 24a, water can be completely stopped.

Also, the air supply hole 7h is the spring seat 7i of the bellows spring g.
Since the position of the dew condensed water in the pump is shifted from the position of the bellows spring 7g, it is difficult to condense water in the water container 9 due to the spring seat 7i of the bellows spring 7g. The problem will also be resolved.

In the above embodiments, a prismatic body was described, but even in a commonly seen approximately cylindrical body, the air pump air supply hole may be eccentrically provided on the valve housing cylinder side with respect to the center line of the water container. As a result, both the valve housing cylinder and the air supply hole are submerged on or within the liquid surface, and a similar effect can be obtained.

Effects of the Invention As is clear from the above embodiments, the air pot of the present invention has the following excellent effects.

(1) Since the air pump's air supply is placed on the side of the valve housing cylinder with reference to the center line of the water container, if the vessel falls over, both the valve housing cylinder and the air supply hole will be submerged on or within the liquid surface. Therefore, the liquid content does not leak into the container, making it extremely safe.

(2) Since the air supply hole is shifted from the position of the spring seat of the bellows spring, the dew water in the bellows is always condensed and circulated in the water container, which is good for hygiene.

It has the above-mentioned effects, and its industrial value is extremely great.
