Claims (1)

[Scope of utility model registration request] An inner container equipped with a heating element is provided, a drainage member is fitted to the upper end of an outer case surrounding the inner container, an inner stopper is removably attached to the center opening of the drainage member, and a bellows pump is attached to the upper end of the drainage member. Attach the built-in upper cover so that it can be opened and closed freely, fit a rubber valve into the center opening of the lower cover that covers the lower surface of the upper cover, insert the air outlet of the bellows pump into the rubber valve, and release the bellows by pressure from the bellows pump. The compressed air inside the pump is supplied into the inner container through the air circulation part in the inner stopper, and the liquid in the inner container is discharged to the outside of the pot via the pumping pipe, the liquid circulation part in the inner stopper, and the discharge pipe. In the electric pot, an annular hanging rib is provided on the outer periphery of the lower end of the central opening of the lower lid, and an annular groove on the outer periphery into which the central opening of the lower lid is fitted into the upper part of the rubber valve and the lower end opening of the bellows pump is fitted. A cylindrical body portion having a locking inner circumferential annular groove is provided, and a flat upper surface portion extending from the outer periphery of the lower end of the cylindrical body portion is brought into contact with the lower surface between the central opening of the lower lid and the annular hanging rib, The bellows-shaped abdomen extending from the tip of the upper flat part contacts the inner periphery of the annular hanging rib of the lower lid, and the flat flat part extending inward from the lower end of the abdomen contacts the outer periphery of the upper end of the air circulation part on the upper surface of the inner plug. An electric pot that uses pneumatic pressure.
