Because it is screwed to the protrusion of the lid, the lower lid and lower plate are securely tensioned, and air and steam do not leak from the screwed parts on the bottom of the lower plate toward the lower lid.
Since there is no risk of steam leakage or discharge failure due to air leakage, it is extremely safe and can provide a sufficient discharge amount.

ポツト。 A discharge mechanism is constructed in which a heating element is stretched around the outer periphery of the lower part of the inner container, a drainage member is connected to the upper end of the outer case surrounding the inner container, and a bottom member is connected to the lower end to discharge the liquid in the inner container to the outside. A top lid case with a built-in bellows pump is pivoted to the top end of the draining member so that it can be opened and closed.
A lower lid is provided with an opening in the center that communicates with the air exhaust hole of the bellows pump, and this lower lid covers the lower end of the upper lid case. A lower plate is provided, and this lower plate is connected to the lower end of the lower lid to close the mouth of the inner container, and the liquid in the inner container is heated by a heating element, and compressed air is introduced into the inner container by the pressure of the bellows pump. In an electric pot using pneumatic pressure, which pumps the liquid inside the inner container and discharges the liquid from the inner container to the outside by a discharge mechanism, protrusions for the lower plate are placed at a predetermined interval on the lower end of the circumferential surface away from the central opening of the lower lid. A heat-resistant, corrosion-resistant sealing material is placed between the protrusion of the lower cover and the upper surface of the lower plate, and it is secured with screws from the lower surface of the lower plate toward the protrusion of the lower cover. An electric pot that uses air pressure.
