Problems solved by technology

[0002] Existing power circuits used in pressure cookers, pressure cookers or rice cookers of different power need to apply power circuits of different specifications, and the volumes of power circuits of different specifications are different, resulting in different sizes of power boxes, and the inside of the pressure cooker is used to install the power box. At the same time, pressure cookers with different power need to install power boxes of different specifications. When installing the power box, it is easy to install the wrong one, so that the pressure cooker does not match the power box, and it is easy to burn out the circuit when the pressure cooker is working.

Description

[technical field] [0001] The invention relates to a power circuit. [Background technique] [0002] Existing power circuits used in pressure cookers, pressure cookers or rice cookers of different power need to apply power circuits of different specifications, and the volumes of power circuits of different specifications are different, resulting in different sizes of power boxes, and the inside of the pressure cooker is used to install the power box. At the same time, pressure cookers with different powers need to install power boxes of different specifications. When installing the power box, it is easy to install the wrong one, so that the pressure cooker does not match the power box, and it is easy to burn out the circuit when the pressure cooker is working. [Content of the invention] [0003] The present invention overcomes the disadvantages of the above technologies, and provides a power circuit, a dual-purpose power circuit for a pressure cooker and an electric rice coo...
