Control method of electric rice cooker

Abstract

The invention provides a control method of an electric rice cooker. The electric rice cooker comprises a cooker cover, an inner pot, a rotating driving device, a heating device, a cover opening induction device and a controller; the rotating driving device drives the inner pot to rotate, the heating device heats the inner pot, the cover opening induction device is used for detecting whether the cooker cover is in an opened or closed state, and the controller is connected with the cover opening induction device, the heating device and the rotating driving device. When the cover opening induction device detects that the cooker cover is in the opened state, the controller controls the inner pot to stop working or rotate in a speed reducing mode. According to the control method of the electric rice cooker, in the rice cooking process, if a user opens the cooker cover carelessly, the cover opening induction device can detect that the cooker cover is in the opened state in time, the rotating speed of the inner pot is controlled to be decreased through the controller, and the situation that the user is scalded due to the fact that the inner pot rotates at a high speed, and rice water is thrown out of the inner pot is avoided.

Description

technical field [0001] The invention relates to the field of household cooking appliances, and more specifically, to a control method for an electric rice cooker. Background technique [0002] When the existing electric rice cooker is cooking, in order to promote the rice grains to fully absorb water and achieve uniform heating, the inner pot of the electric rice cooker is usually rotated to drive the rice and water in the inner pot to rotate, so as to produce a stirring effect and prevent the rice grains from agglomerating; And a large amount of steam will be generated during the cooking process. In order to improve the cooking efficiency of the rice cooker, a sealing ring is usually set between the mouth of the inner pot and the lid to seal it. However, when the rice cooker is in the closed state, the inner pot is driven to rotate The driving device of the rice cooker not only bears the load of the inner pot and the rice water in the inner pot, but also bears the resistanc...

Problems solved by technology

[0002] When the existing electric rice cooker is cooking, in order to promote the rice grains to fully absorb water and achieve uniform heating, the inner pot of the electric rice cooker is usually rotated to drive the rice and water in the inner pot to rotate, so as to produce a stirring effect and prevent the rice grains from agglomerating; And a large amount of steam will be generated during the cooking process. In order to improve the cooking efficiency of the rice cooker, a sealing ring is usually set between the mouth of the inner pot and the lid to seal it. However, when the rice cooker is in the closed state, the inner pot is driven to rotate The driving device of the rice cooker not only bears the load of the inner pot and the rice water in the inner pot, but also bears the resistance load generated by the sealing ring; when the rice cooker is in the state of opening the lid, the device that drives the inner pot to rotate only bears the load of the inner pot and the rice in the inner pot. The load of water, so the load difference of the rotary drive device is obvious in the two states of opening and closing the cover

[0003] In the above situation, if the user accidentally opens the lid while the inner pot is rotating, the load on the rotating drive device will be released instantly, which will cause the speed of the inner pot to rise instantaneously, thus causing the rice water in the inner pot to be thrown out to the rice cooker. In addition, or the high temperature rice water is thrown onto the user, causing the hidden danger of scalding the user
