Electric pan, an upper cover thereof and control method

Abstract

The invention provides an electric pan, an upper cover thereof and a control method. The control method is used for controlling the electric pan and includes the steps that an environmental parameter in the electric pan is detected; whether the environmental parameter reaches a preset value or not is judged; when the value of the environmental parameter reaches the preset value, a steam channel is opened by an opening and closing device; if the value of the environmental parameter does not reach the preset value, the steam channel is closed by the opening and closing device. According to the provided method, when steam needs to be exhausted, namely the environment parameter reaches the preset value, the steam channel is opened; when steam does not need to be exhausted, namely the environment parameter does not reach the preset value, the steam channel is closed. Unnecessary heat loss is avoided, and it is avoided that external bacteria, dust and the like enter the steam channel to affect safe and sanitary use of the electric pan.

Description

technical field [0001] The present invention relates to the field of electric heating pans, and more specifically, relates to an upper cover of an electric heating pan, an electric heating pan including the upper cover, and a control method for controlling the electric heating pan. Background technique [0002] The electric heating pot will generate a large amount of water vapor during the cooking process. In order to guide and discharge the water vapor to the outside of the electric heating pot, the upper cover of the electric heating pot is usually provided with a steam channel for the free discharge of water vapor. However, the existing steam channels are all set to a normally open state, that is, the steam channels are all open no matter what state the electric heating pot is in. This setting method has the following problems: On the one hand, the long-term opening of the steam channels will cause bacteria in the external air Foreign objects such as dirt and dust enter t...

Problems solved by technology

However, the existing steam passages are all set to a normally open state, that is, the steam passages are open no matter what state the electric heating pan is in. This setting method has the following problems: On the one hand, the long-term opening of the steam passages will cause bacteria in the external air Foreign objects such as dust and dust enter the electric heating pot along the steam channel; on the other hand, when the electric heating pot is in the working stage of stewing rice, keeping warm, etc. that do not need to discharge water vapor, the heat inside the electric heating pot will flow from the steam channel due to the open steam channel. It will not only affect the rice cooking and heat preservation effect of the electric heating pot, but also cause unnecessary energy loss
