Electric cooking device, control circuit of electric cooking device and cooking method of electric cooking device

Abstract

The invention discloses an electric cooking device, a control circuit of the electric cooking device and a cooking method of the electric cooking device. The control circuit of the electric cooking device comprises N+1 coil disc modules, a power module, N switch modules, N+1 power switch drive modules and a controller; the first end of each switch module is connected with the power module, the second end of the ith switch module is connected with the ith coil disc module, the third end of the ith switch module is connected with the (i+1)th coil disc module, and i is equal to 1,2,3,...,N; the controller comprises N+1 power switch drive ends and N switch control ends; each power switch drive end is correspondingly connected with the corresponding power switch drive module, and each switch control end is connected with the fourth end of the corresponding switch module; and according to the control circuit, through control over the number and the combined type of working coils, the heating power of the electric cooking device is adjusted, the electric cooking device can work at a lower power, and the adjustable range of the heating power of the electric cooking device is wide.

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, an electric cooker with the control circuit and a cooking method of the electric cooker. Background technique [0002] In electric cookers such as electric rice cookers, induction cookers, electric pressure cookers and other products, when using double-segment wire coils for heating, the wire coils can be divided into inner and outer double wire coils for heating, so as to achieve external convection and uniform heating, but the power range that can be adjusted Narrow, limited heating at low wattage. [0003] Therefore, it is necessary to improve the heating control technology of the existing electric cooker. Contents of the invention [0004] The object of the present invention is to solve at least one of the above-mentioned technical drawbacks. [0005] For this reason, an object of the present invention is to pro...
