Electric cooker and control circuit thereof

Abstract

The invention discloses an electric cooker and a control circuit thereof. The control circuit of the electric cooker comprises N coil panel modules, a power module, N power switches, N driving modules, a synchronous signal detection module and a control module, wherein the power module is used for supplying power to the N coil panel modules; the power switches are connected with the coil panel modules in a one-to-one correspondence mode to form N resonance heating loops; the driving modules are connected with the power switches in a one-to-one correspondence mode so as to drive the power switches correspondingly; the synchronous signal detection module is used for detecting a synchronous signal of each resonance heating loop independently; the control module can control all the resonance heating loops to work independently at the same time or control each resonance heating loop to work independently according to the synchronous signals detected by the synchronous signal detection module. The control circuit can control all the resonance heating loops to work independently at the same time or control each resonance heating loop to work independently, so that the cooking requirement of users is fully met.

Description

technical field [0001] The invention relates to the technical field of electric heating appliances, in particular to a control circuit of an electric cooker and an electric cooker with the control circuit. Background technique [0002] In electric cookers such as rice cookers, induction cookers, electric pressure cookers and other products, multi-stage IH uses multiple independently working coil disks for heating control. Most of the current control schemes use series, parallel or scanning methods for heating. Usually, each section of coil cannot be controlled independently or the power of each section of coil cannot be adjusted independently, which cannot meet the cooking needs of users and brings inconvenience to users' lives. Contents of the invention [0003] The object of the present invention is to solve at least one of the above-mentioned technical drawbacks. [0004] Therefore, an object of the present invention is to provide a control circuit for an electric cook...
