Self-gravity pressure control energy-saving electric rice cooker

Abstract

The invention discloses a self-gravity pressure control energy-saving electric rice cooker, which comprises a cooker body (1), a heating disc (13), an inner liner (2) and a heating control circuit, wherein an open slot is arranged on an outer side edge at the upper end of the inner liner, and a convex surface at the upper end of the cooker body is matched with the open slot; an inner cover (7) comprises a circular rigid plate and an elastic soft rubber (3), an exhaust valve (9) is arranged at the middle part of the inner cover, a seal ring (10) is arranged between a valve body of the exhaust valve and the inner cover, the upper end of the exhaust valve is movably connected with a lifting pull rod (8) arranged on an upper cover (6), and a locking mechanism is arranged between the upper cover (6) and the inner liner (2); a U-shaped control rod (4) and a support (5) are arranged on the upper cover; and a limit switch (14) which is connected with a rice cooking switch in series is arranged on the cooker body. The self gravity of the electric rice cooker is adopted for controlling the working pressure of the inner liner, thereby breaking through the bottleneck that a traditional electric pressure rice cooker has potential safety hazard because of the working mode of intermittent heating and continuous pressure relief, and achieving the effects of energy saving, high safety, simple structure and low manufacturing and processing cost.

Description

technical field [0001] The invention relates to a household electrical appliance, in particular to a self-gravity pressure-controlled energy-saving electric rice cooker. Background technique [0002] At present, electric rice cookers are divided into ordinary electric cookers and electric pressure rice cookers according to the pressure in the pot. Ordinary electric rice cookers are simple in structure and low in processing cost. When cooking rice, the water must be heated after it boils completely, which wastes energy, and when cooking porridge, the soup overflows. The electric pressure rice cooker uses high pressure and high temperature to cook rice. The rice is soft, tastes good, and has no overflow. It is more energy-efficient than ordinary rice cookers. The displacement is very small, which may easily cause the switch not to operate, and after the power is cut off, the pressure in the pot will continue to rise. The impulse of a good-quality electric pressure cooker is a...

AI Technical Summary

Problems solved by technology

This utility model adopts the self-gravity (micro-pressure) of the electric cooker to control the energy-saving electric cooker of the inner tank, which breaks through the intermittent heating of the traditional electric pressure cooker and continuously releases the pressure. There is also a common problem that after the electric pressure rice cooker is powered off, the pressure in the cooker will continue to rise, and the preparation process and structure are complicated.
