Example Embodiment

[0020] A further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention:

[0021] like Figure 1-4 As shown, an electric heating switch circuit for an electric rice cooker for both porridge and rice, including a rice cooker body 1, a heating plate 2 arranged on the inner bottom surface of the rice cooker body 1 to contact and heat the inner tank, and a steam port arranged on the rice cooker body 1 3. A power supply end of the electric rice cooker and one end of the heating plate 2 are sequentially connected in series with a bimetal temperature control button switch 4, which is set on the body 1 of the electric rice cooker and is used to close and reset when heated to disconnect the heating circuit of the electric cooker. The cooking temperature control switch 5 that is in contact with the heating plate 2 and reaches the set cooking temperature when the heating plate 2 cooks and reaches the set cooking temp...

Abstract

The invention discloses an electric heating switch circuit of a porridge and rice dual-purpose electric cooker. The electric heating cooker comprises an electric cooker body, a heating plate and a steam port, a bimetallic strip temperature control key switch, a rice cooking temperature control switch and a function setting key are sequentially connected in series between one power supply end of the electric cooker and one end of the heating disc; the rice cooking temperature control switch is connected with a heating element in parallel; the function setting key is connected with a porridge cooking temperature control switch in parallel; the tripping temperature of the porridge cooking temperature control switch is lower than that of the rice cooking temperature control switch; the other power supply end of the electric cooker is connected with the other end of the heating disc; when a normally-closed bimetallic strip rice cooking temperature control switch reaches a set cooking temperature, the heating body is powered on and emits heat to enable the closed bimetallic strip temperature control key switch to be heated and tripped off, the function of controlling the electric cookerto stop heating after rice cooking is completed is achieved, meanwhile, the rice cooking and porridge cooking function setting key is further arranged, the normally closed bimetallic strip porridge cooking temperature control switch is connected through the function setting key, and the porridge cooking spill-proof function is achieved.

Description

[technical field] [0001] The invention relates to an electric heating switch circuit for an electric rice cooker with dual functions of congee and rice. [Background technique] [0002] Most of the existing electric cookers are controlled by a magnetic steel temperature controller. When the temperature in the electric cooker reaches the set temperature, the magnetic steel on the bottom heating plate will lose its magnetism, and the heating switch will be pushed through the lever principle to stop the heating of the electric cooker. However, it is necessary to install the lever and adjust the magnet when assembling the temperature control components with the magnet and the lever. At the same time, due to the complicated assembly, the different magnetic structure in the magnet, and the different radian of the manually adjusted lever, the temperature control ability of the rice cooker is different, and it cannot even meet the expected use. Standards affect the function of the ri...
