There is an accurate pressure-controlling electric rice
cooker, which contains an inner pot inside pot body crust, and the inner pot is connected with electric plate, and there is a resilient seal ring between the inner pot and pot cover. Between the crust and the inner pot there is a middle pot; between the crust and the middle pot there is a heat-insulating layer. The electric rice
cooker has a
pressure switch, which contains an air duct or
air channel connected with inner pot chamber. The other end of the air duct or
air channel is communicated with a pressure membrane case, in which there are movable membranes that are joined with push rod. On the other side of the push rod there is a movable contact spring, which connects with an unmovable contact spring, and both the two contact springs couple with main controlling electric of electric rice
cooker separately. This invention has simple and reasonable structure, its pressure controlling is accurate, safety degree is high, and after cooking it can exhaust quickly and safely,
discharge pressure in blocked style, and its heat insulation effect is good, heat
conductivity is high and is energy saving.
