Electric cooker and control circuit thereof

The invention discloses an electric cooker and a control circuit thereof. The control circuit comprises N coil panel modules, a power source module, N power switches, N drive modules, N switch control modules, N temperature detection modules and a controller. The power switches are connected with the coil panel modules in a one-to-one correspondence manner. The drive modules are connected with the power switches in a one-to-one correspondence manner. The switch control modules are connected with the drive modules in a one-to-one correspondence manner. Each temperature detection module is used for detecting the temperature of the corresponding power switch. The controller comprises a temperature detection end, a power switch drive end and N switch control ends. The temperature detection end is connected with the N temperature detection modules. The power switch drive end is connected with the N drive modules. The switch control ends are connected with the switch control modules in a one-to-one correspondence manner and connected with the corresponding temperature detection modules. By the adoption of the control circuit, a chip port of the controller can be eliminated, and cost can be lowered greatly.
