Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a water pot that stores a liquid such as water in an inner container and heats and boils the liquid to keep it warm.

(Prior art) Generally, in order to bring out the taste and aroma of tea, coffee, black tea, etc., it is necessary to remove the unique taste caused by limescale, etc. in tap water, and it is also necessary to remove such unique taste. Boiling tap water is a widely known method.

However, this type of boiling type jar pot has the disadvantage that steam generated by boiling enters the bellows pump made of polyethylene resin or polypropylene resin, deteriorating the bellows pump.

In order to eliminate this drawback, for example, Japanese Patent Application Laid-Open No. 59-160417
No. and Japanese Patent Application Laid-open No. 164020/1983, there is a lid assembly provided with a steam release passage for releasing steam generated in the inner container to the outside when the bellows pump (manual pump in the publication) is not operated.

(Problems to be Solved by the Invention) However, such a structure has the disadvantage that it takes time to disassemble and assemble when, for example, repairing the steam discharge passage, etc., and it is very time-consuming from the point of view of serviceability.

(Means for Solving the Problems) The present invention has been made in view of the above-mentioned problems, and includes a steam release passage outside the lid assembly that communicates with the inner container when the bellows pump is not operated. A bellows gasket is provided at the air outlet to block the air outlet of the bellows pump and prevent steam from entering the pump when the pump is not operated. To obtain a pump that prevents pump deterioration and improves serviceability.

(Function) By doing this, the steam generated during boiling will be released to the outside of the jar pot from the steam release passage provided in the lid assembly when the bellows pump is not operated, and the steam release passage will also be located in a position that is very easy to repair. Become.

(Example) An example of the present invention will be described below with reference to the drawings.

The structure of this embodiment is as shown in FIG. 1, in which reference numeral 1 denotes an inner container for storing liquid, and a belt-shaped heater 2 for heating and keeping the liquid warm is wound around the outer periphery of the lower part. 3 is a dispensing channel for dispensing liquid;
One side is opened at the bottom of the inner container 1, and the other side is opened at the bottom of the sprue cover 4 located at the front of the jar pot. A movable steel ball 5 is provided. Reference numeral 7 denotes an outer frame, which is made of a printed steel plate or the like and forms the outer side of the jar pot.
is connected and fixed to the outer bottom of the inner container 1. 1
Reference numeral 1 denotes an inner lid, which is located on the upper part of the inner container 1 and closes the opening of the inner container 1. The outer periphery of the inner lid 11 is provided with an inner lid packing 12 for maintaining airtightness. Inner container 1 and lid assembly 13 are in the center.
An inner lid knob 16 is provided with a steam passage 15 that communicates with a lid ring 14 provided at the lowest center of the lid. Reference numeral 17 denotes a cylindrical main body ring located on the upper part of the outer frame 7, which supports the inner container 1 on the inner diameter side, and is provided with a hinge groove 18 on the rear side of the main body ring 17, which is the center of rotation of the lid assembly 13. ,on the other hand,
The front side is provided with claw grooves 21 that engage with claws 20 of lock buttons 19 arranged on both sides of the front face of the lid assembly 13. The lid assembly 13 includes a lid main body 22 and a lid main body 2.
A bellows pump 26, which will be described later, is provided inside the lid assembly 13, and a lid cover 23 that closes the lower opening of the lid assembly 13 forms an outer shell. While placing the ring 14, the lid ring 14
An air supply port 24 is formed in the center. Reference numeral 25 denotes a steam release passage, which is located at the bottom of the lid cover 23 and is provided outside the lid assembly 13 so as to communicate with the air supply port 24.
This is where the steam generated in the inner container 1 is released to the outside. 26 is a bellows pump for air pressure feeding.
An upper plate member 27 is provided at the upper part, and the upper plate member 27
A sealing gasket 29 made of silicone rubber or the like is arranged around the outer periphery of the central air intake port 28 formed in the air.
Furthermore, a seal cap 3 is provided on the upper part of the sealing packing 29 for making contact with this sealing packing 29.
0 is arranged via an intake spring 31,
Intake spring 3 of bellows pump 26 when not operated
1, the seal gasket 29 and seal cap 30 are separated. A bellows spring 32 is provided in the bellows pump 26 and always urges the bellows pump 26 in the direction of expansion. 33 is a hollow bellows shaft,
It is arranged so as to pass through the center of the bellows pump 26 and protrude from an air exhaust port 34 provided at the center of the lid cover 23. Reference numeral 35 denotes a bellows gasket, which is elastic and is made of silicone rubber or the like and is fixed to the bellows shaft 33 and the air outlet portion 34, respectively, and is provided so as to wrap around the tip of the bellows shaft 33. Reference numeral 36 denotes a membrane-like valve portion located at a portion corresponding to the air supply port 24 of the bellows packing 35. For example, a cross cut (not shown) is made therein, and the bellows pump 2
6. When not operated, the hollow portion of the bellows shaft 33 is closed to prevent steam from entering the bellows pump 26. Reference numeral 37 denotes a push plate, which is arranged so as to come into contact with the upper surface of the seal cap 30, and is used for pressing operation when operating the bellows pump 26.

Next, the operation of this embodiment will be described.

When the bellows pump 26 is not operated, the push plate 37 is not pressed as shown in FIG.
4. The steam is led to the outside of the jar via a central air supply port 24 from a steam release passage 25. Further, when the bellows pump 26 is operated, the push plate 37 is pressed as shown in FIG. 2, so that the sealing gasket 29 on the upper part of the upper plate member 27 and the seal cap 30 come into contact with each other. When the push plate 37 is further pushed in, the intake spring 31 urges the bellows shaft 33 downward, and the bellows packing 35 is extended and comes into contact with the peripheral edge of the upper opening of the air supply port 24. Therefore, the air in the bellows pump 26 spreads out the notch part of the membrane valve part 36 of the bellows packing 35, and is forced into the inner container 1 through the air supply port 24 and the steam passage 15, and by this pressurized air. The liquid inside the inner container 1 is discharged from the spouting path 3 to the outside of the jar pot. Further, since the steam passage 25 is located outside the lid assembly 13, it can be disassembled and assembled in a short time when repair work is required.

(Effects of the invention) As described above, according to the invention, a steam release passage communicating with the inner container is provided outside the lid assembly when the bellows pump is not operated, and a bellows prevents steam from entering the air discharge port of the bellows pump. The provision of a gasket improves the serviceability of the steam release passage, and prevents the steam generated during boiling from entering the bellows pump, preventing deterioration of the bellows pump and providing a highly durable jar pot. I can do it.
