Description

[Detailed description of the invention] Industrial applications The present invention heats the liquid in the container using a heater.

This relates to an air pot that not only retains heat but also automatically pours out the liquid inside the container using air sent in from the bellows.

Conventional configuration and its problems General K. In this type of air pot, when the liquid inside the container is to be made to flow out, it is necessary to increase the pressure inside the container. It is necessary to prevent the pressure inside the container from increasing naturally due to generated steam, etc. Otherwise, as the pressure inside the container increases naturally, the liquid inside the container may unexpectedly flow out from the spouting pipe, causing an accident such as splashing the floor or causing burns from boiling water.

However, as shown in FIG. 1, the conventional lid structure of this type of air pot is such that a bellows 102 is provided inside the lid 101 and a ventilation hole 1 is provided in the upper plate 103 of the upper surface of the lid 101.
04 is provided, and this ventilation hole 104 and push plate 105
The structure was such that communication was made with the outside through a gap 106 between the lid body 101 and the lid body 101.

However, in the conventional structure shown in FIG. 1, steam from the hot water stored in the container leaks to the outside from the gap 106 between the push plate 106 and the lid 101 through the above-mentioned path. It wasn't that good. Further, in the conventional structure shown in FIG. 1 above, the lid body 1
01, so if the steam condenses inside the lid 105 etc., the water droplets will form on the lid 10.
1, and these water droplets drip onto the floor when the lid 101 is opened or closed, causing discomfort to the user, which is not desirable.

As another conventional example, as shown in FIG. 2, there was a steam discharge hole 105a provided on the upper surface of the push plate 105, but in this case, the gap 106 between the lid body 101 and the push plate 105 was The lid body 101 prevents steam from leaking to the outside and water droplets accumulating inside the lid body 101.
Not only is it not possible to completely eliminate problems such as dripping onto the floor when opening and closing, but also when operating the push plate 105,
The steam discharge hole 106a becomes easy to touch with the hands, resulting in new drawbacks such as burns and dirt on the hands due to condensation.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks by limiting the air and steam distribution path to one location, and by providing a steam discharge hole other than the operation part of the push plate to avoid user inconvenience. The purpose is to eliminate pleasure while also increasing safety.

Structure of the Invention In order to achieve the above object, the present invention provides a push plate with a protrusion that partially protrudes outward, a lid with a notch corresponding to the protrusion, and a top surface of the bellows. The steam discharge hole and the vent hole of the bellows are connected so that the air or steam discharged from the vent hole provided in the bellows is discharged to the outside from the steam discharge hole provided in the protrusion of the push plate. This configuration prevents steam from escaping from the gap between the lid and the push plate, or from accumulating inside the lid and dripping onto the floor when the lid is opened or closed, as in the case of conventional methods. If you touch the steam outlet and get burned, you will be safe.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 3 to 5, reference numeral 1 denotes a container housed in a cylindrical container outer body 2, and a flange portion 1a is integrally formed at the upper end of the container 1 so as to protrude outward. The container 1 is supported by the spout 4 by placing this flange portion 1a on the inner peripheral flange portion 4a of the spout 4 via the pouring pan king 3.

Reference numeral 6 denotes an inner lid removably placed on the upper opening of the container 1, and an air hole 6a is provided approximately at the center of the inner lid 5, and furthermore, in front of the inner lid 5, there is a valve with a built-in overflow prevention valve 6. It forms a chamber 7. Further, a support frame 8 made of a stainless steel plate or the like is fixed to the lower surface of the inner lid 5 with screws 8a. 9
is a container backing that is removably attached between the inner lid 5 and the support frame 8, and this container backing 9 allows the container 1 to be
Keeps the inside airtight. Reference numeral 10 denotes a water rising pipe provided from the valve chamber 1 to the bottom of the container 1, and the upper end of this water rising pipe 10 is connected to the -C pouring vibrator 11 via a valve cover 12. The spout pipe 11 is provided with a spout 11a whose upper end protrudes outward from the container 1 and whose tip opens downward.

Reference numeral 13 denotes a lid body pivotally attached to the rear of the spout 4 so as to be freely openable and closable, and the lid body 13 has an inner cylindrical part 13b which is open on the "-" face and has a notch part 13a at the rear part. , a push plate 14 having a protrusion 14a corresponding to the notch 13a is provided in the inner cylinder 13b so as to be vertically slidable, that is, to be freely retractable. There is still a cylindrical portion 14b projecting downward at the center of the back surface of this push plate 14.
are integrally formed.

16 is a bellows arranged below the push plate 14, and the upper end 15a of the bellows 16 has a ventilation hole 15b in the center.
A movable valve 16 is provided in the bracket ventilation hole 15b. The movable valve 16 moves up and down within a certain range, and when the push plate 14 moves downward,
The ventilation hole 15b is pushed by the lower end of the cylindrical part 14a.
The vent hole 15b is opened when the push plate 14 is moved upward and the vent hole 15b is closed. Further, a compression coil spring 17 is interposed between the movable valve 16 and the inner bottom portion 15a of the bellows 15, and is biased in a direction that constantly pushes the push plate 14 upward. Reference numeral 16d designates a spout port provided approximately at the center of the inner bottom portion 15c of the bellows 15.

Further, the bellows 1.5 is fixed at its lower end to a lid cover 18 that closes the lower end opening of the lid body 13, and communicates with the air hole 5a of the inner lid 5 via a lid gasket 19. Reference numeral 2o denotes a steam cover whose lower end is press-fitted to the upper end 15a of the bellows 15. This steam cover 20 moves up and down as the bellows 15 expands and contracts, and engages with the elbow 21 with one force to close the bellows 15. The passage A hole 1sb and the steam discharge hole 14C provided in the push plate 14 are communicated with each other. The steam cover 20 also has a downwardly projecting cylindrical rib 20a formed on its inner surface, and the end surface of the cylindrical rib 20a is normally positioned so that it is almost in contact with the movable valve 16. The outer diameter of the cylindrical portion 14b of the push plate 14 and this cylindrical rib 20a
There is only a minimum gap necessary for sliding of the push plate 14 between the inner diameter of the press plate 14 and the inner diameter of the press plate 14, and as the two are kept close to each other, steam will not leak from this part.

22 is a protection plate for the bellows 16; 23 is a suppression ring for the push plate 14; 24 is a lock knob for locking and unlocking the lid 13 attached to the spout 4 so as to be openable and closable by a pivot 26; It is a lock spring.

” The operation will be explained in the second configuration. Now, when water is stored in the container 1, the inner lid 5 is fitted, the lid 13 is closed, and electricity is applied, the water in the container 1 is heated. As the water boils, steam is generated, and this steam is released into the inner lid 6.
It passes through the air hole 6a provided in the air outlet 15d, the air vent 15b, and the steam cover 20. The steam passes through the elbow 21 and is discharged to the outside of the vessel from a steam outlet 14c provided outside the operating section of the push plate 14. At this time, the steam passing through the vent hole 16b provided at the upper end of the bellows 15 is kept airtight with the movable push plate 14 by the steam cover 20, so that all the steam is introduced into the elbow 21.

Therefore, the steam does not condense inside the lid 13 and drip onto the floor when the lid 13 is opened and closed, and the steam still accumulates inside the container 1 and the liquid inside the container 1 flows from the spout 11a. Accidents such as natural outflow of water can also be prevented.

When the liquid in the container 1 is poured out by operating the bellows 16, as shown in FIG. In order to avoid the blockage, the inside of the bellows 16 becomes sealed except for the jet nozzle 15d at the lower end. Therefore, when the push plate 14 is further pushed down from this state, the air inside the bellows 15 passes through the air hole 5a. The liquid in the container 1 is pumped into the container 1 under the pressure of the water raising vibrator 10. Valve chamber7. Discharge port 11a via water injection pipe 11
It is pushed out of the vessel. By repeating this operation, you can pump out the required amount of hot water. At this time, the operation part of the push plate 14 has a steam discharge hole 14c.
Since there is no such thing, there is no fear of burns or the like when operating the push plate 14, unlike in the conventional case.

Effects of the Invention As described above, according to the present invention, air or steam discharged from the ventilation holes provided on the two sides of the bellows is discharged to the outside from the steam discharge holes provided in the protrusion of the push plate. Since the steam discharge hole and the bellows ventilation hole are in communication, it is possible to prevent natural pressure build-up, and the steam can always be discharged from a fixed location. This prevents steam from leaking out through the gaps or from accumulating inside the lid and dripping onto the floor when the lid is opened or closed, eliminating discomfort for the user and making it easier to press the button to pour out the liquid in the container. When operating the plate, the steam is discharged from the steam discharge hole in the protrusion that protrudes outward from the operation part of the push plate, so there is no risk of burns if your hand touches the steam discharge hole when operating the push plate. This makes it possible to provide an air pot with extremely high safety.
