Claims (1)

[Scope of utility model registration request] A heating element is installed at the bottom of the bottomed cylindrical inner container, a shoulder member is connected to the upper end of the outer case surrounding the inner container, a bottom member is connected to the lower end, and the liquid inside the inner container is discharged to the outside. A discharge mechanism is provided at the upper end of the shoulder member, and a lid body consisting of an upper lid and a lower lid with a built-in bellows pump is provided at the upper end of the shoulder member, and a central opening is bored in the center of the lower lid to communicate with the air exhaust cylinder provided at the lower end of the bellows pump. A plurality of bosses hang down at predetermined intervals around the lower surface of the lower lid, while a sealing pad is stretched around the outer peripheral edge to seal the opening of the inner container, and a seal gasket is placed in the center to cover the lower surface of the lower lid. A stainless steel cover plate with an opening is provided, the cover plate is screwed to the boss part of the lower cover, the cover body is removably attached to the inner container via this cover plate, and the inner container is heated by the heating element. The liquid inside is heated, and the compressed air inside the inner container is pumped by the pressure of the bellows pump.
In an electric pot using pneumatic pressure that discharges the liquid inside the inner container to the outside, the lower lid having the boss portion is formed in the shape of a saucer having an outer wall and a bottom wall, and an upper portion is formed on the outer peripheral edge of the bottom wall. Providing an elongated annular short side wall,
A flat plate portion extending from this short side wall toward the outer wall is provided, and a small annular rib that restricts the outward expansion of the seal packing is suspended from the lower end of the outer wall, while a flat plate portion extending upward from the outer circumferential wall of the cover plate is provided. An annular side wall is provided that extends and abuts against the short side wall of the lower cover, and an outer flange is integrally molded outward from the upper part of the annular side wall and abuts against the flat plate portion of the lower cover. a contact portion sandwiched between the flat plate portions of the lower lid;
A pneumatic electric pot characterized by being provided with an annular tongue integrally molded from the outer peripheral end of the abutment portion, extending downward in a curved manner, and abutting against the mouth of the inner container.
