Description

[Detailed Description of the Invention] The present invention is capable of heating the liquid in a liquid container using a water heater, and also uses pressurized air from an air pump installed at the top of the pot to heat the liquid in the liquid container. This invention relates to a kettle-type pump-type pot that extrudes liquid through a series of passages that communicate the inside and outside.

In conventional pump-injection pots (non-kettle type) that use a bellows-type air pump, steam inside the medium bottle is released through an inlet formed in the top plate of the pump. It has been found that if the steam venting structure of a pump injection type pot is applied as is to a water boiler type pump injection type pot, the following problems will occur. A large amount of steam is generated when the pump generates heat, but if this steam is left to be released from the inlet on the top of the pump, it may leak in unspecified directions from various holes or gaps in the lid. Otherwise, the entire lid may become so hot that the user may suffer accidental burns.

Another problem is that the steam released from the pump suction port flows into all parts of the lid, and the steam tends to corrode the spring of the lid locking member, the pump mounting screws, etc.

In view of the above-mentioned problems with the water boiler type pump injection pot, the present invention has been developed to seal the outside of the pump suction port with an upward cylindrical part formed on the top plate of the pump and a downward cylindrical part formed on the pump operating member. By enclosing it in a relatively simple configuration (low number of parts and assembly man-hours), steam released upward from the pump suction port can be prevented from leaking into the inside of the lid body.
In addition, the air can be concentrated into the outside air from several places, and the upward cylindrical portion and the downward cylindrical portion are slidably fitted to each other over the entire circumference, thereby making it easier to operate the pump. It is an object of the present invention to provide a water boiler type pump pouring pot that can reliably guide a pump operating member at times.

In addition, the pump operating member 10 and the pump operating member 10 are connected to each other because the downward cylindrical portion 34 of the pump operating member 10 and the upward cylindrical portion 37 of the pump top plate 21 are slidably fitted to each other. The pump top plate 21 and the pump top plate 21 are mutually guided and are prevented from shifting in the horizontal direction, so that the air pump 9 can be operated in a stable state.

Next, to explain the effects of the present invention, the water boiling pump type pot of the present invention has the following effects.

(1) An upward cylindrical portion 37 is formed on the pump top plate 21 so as to surround the outside of the suction valve 25, and is slidably fitted to the cylindrical portion 37 facing upward on the pump operating member 10 over the entire circumference. A downward cylindrical portion 34 is formed to fit the pump operating member 10, and a space 3 surrounded by the respective cylindrical portions 37, 34 is provided.
1 is formed with a steam vent hole 32 that opens into the lid body, so even when steam generated during liquid heating is released from the pump suction port 24, the steam leaks irregularly from various holes and gaps in the lid body. Since the entire lid is not heated to a high temperature, it is possible to reduce the risk of burns caused by the user coming into contact with irregularly leaking steam or the high-temperature lid.

(2) Since a large amount of steam does not fill the entire lid body, metal parts such as the spring 42 for the lid locking member and the screws 42 for attaching the air pump are less likely to corrode.

(3) Since the upward cylindrical portion 37 is formed on the pump top plate 21 and the downward cylindrical portion 34 is formed on the pump operating member 10, the structure is configured so that steam released from the pump suction port 24 does not leak into the inside of the lid body. Even if it is made by using the same method, it is possible to reduce the number of parts and the number of assembly steps.

(4) Since the upward cylindrical portion 37 and the downward cylindrical portion 34 are slidably fitted to each other, the pump operating member 10 is guided more reliably during pump operation, and the pump operating member 10 The pump top plate 21 will not be horizontally displaced from each other.
