Electric pressure rice cooker, automatic locking device, automatic pressure locking function control method

Abstract

The invention provides an electric pressure rice cooker with an automatic pressure locking function, a method for controlling the automatic pressure locking function of the electric pressure rice cooker, and an automatic locking device for the electric pressure rice cooker, which include: an inner pot formed with a hooking protrusion; The outer pot; the lid; the pressure joint, including the locking wheel, the locking wheel is provided with a plurality of hooking grooves, and when the lid covers the outer pot, the plurality of hooking grooves are located in the second position Respectively combined with a plurality of hooking protrusions (ie, in a pressure-locked state), the plurality of hooking grooves are released from a plurality of hooking protrusions (ie, released from a pressure-locked state) when located in the first position; the position sensing part , to sense the locked wheel; the driving part, which provides a rotational force to rotate the locked wheel; and the control part, which controls the cooking action, and reduces the driving at a certain deceleration ratio when the locked wheel is sensed to rotate to approach the first position or the second position part of the rotational force and eventually bring the locking wheel to a complete stop.

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.
