How to control the rice cooker

Abstract

The invention provides a control method for an electric rice cooker. The electric rice cooker includes a lid, an inner pot, a rotary driving device, a heating device, a cover opening sensing device and a controller. The rotating driving device drives the inner pot to rotate, the heating device heats the inner pot, and the lid opening sensing device is used to detect the When the lid is opened or closed, the controller is connected with the lid opening sensing device, the heating device and the rotation driving device. When the lid opening sensing device detects that the lid is in the open state, the controller controls the inner pot to stop working or slow down the rotation. In the control method of the electric rice cooker provided by the present invention, if the user accidentally opens the lid during the cooking process, the lid opening sensing device can detect in time that the lid is in an open state, and the speed of the inner pot is reduced by the controller to avoid the The high-speed rotation of the inner pot causes rice water to be thrown out of the inner pot, scalding the user.

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
