ELECTRIC PRESSURE RICE COOKER, AUTO LOCKING DEVICE, automatic pressure locking function control method

Abstract

The invention provides an electric pressure rice cooker with an automatic pressure locking function, an automatic pressure locking function control method for the electric pressure rice cooker, and an auto looking device for the electric pressure rice cooker. The auto looking device includes an inner cooker forming hanging projections, an outer cooker, a cover and a pressure combination part including a locking wheel provided with a plurality of hanging grooves; in the state that the cover covers the outer cooler. The hanging grooves are joint with the hanging projections at a second position (i.e., a pressure locking state), and the hanging grooves releases the hanging projections at a first position (i.e., a pressure locking releasing state); a position sensing portion is used for sensing the locking wheel; the driving portion is used for providing a rotary force for allowing the locking wheel to rotate; and a control portion is used for controlling cooking actions and reducing the rotary force of the driving portion at a certain reduction ratio and finally allowing the locking wheel to stop rotation completely when it is sensed that the locking wheel rotates near the first position or the second position.

Description

technical field [0001] The invention relates to an electric pressure rice cooker which realizes an automatic pressure locking function through an automatic locking device and a control method for the automatic pressure locking function of the electric pressure rice cooker. Background technique [0002] Generally speaking, an electric pressure rice cooker is a device that maintains the inside of the inner pot at a certain pressure and cooks by using electric heat. The lid of the pot constitutes. [0003] In addition, there has been disclosed an electric pressure rice cooker in which cooking is performed by sealing the inner pot to pressurize the inside of the inner pot with water vapor, when the cooking mode is selected with the lid closed, the automatic The above-mentioned lid is locked to the main body (or the outer pot), and when the cooking is completed, the main body is automatically unlocked to the above-mentioned lid. [0004] However, the disclosed electric pressure...

AI Technical Summary

Problems solved by technology

Therefore, in the disclosed electric pressure rice cooker, when the motor starts or stops rotating, the motor and various parts connected to the motor are more likely to be damaged.

[0005] In addition, the disclosed electric pressure rice cooker does not provide a processing method for the failure of the pressure lock or the release of the pressure lock due to the operation error of each part of the electric pressure rice cooker.

[0006] In addition, in the disclosed electric pressure rice cooker, when cooking and cooking, the internal temperature rises to about 100°C, so there is a problem that the motor does not operate normally due to such heat.
