Cooking appliance and electric heating device for same

Abstract

The invention discloses a cooking appliance and an electric heating device for the cooking appliance. The electric heating device comprises an interactive interface, a first inductor, an IGBT, a resonance coil, a first capacitor, a second capacitor, a third capacitor, a switching assembly and a control circuit. The first end of the first inductor is connected with a power source, the first end of the IGBT is grounded, the first end of the resonance coil is connected with the second end of the first inductor, the second end of the resonance coil is connected with the second end of the IGBT, the first end of the first capacitor is connected with the first end of the resonance coil, the second end of the first capacitor is grounded, the first end of the second capacitor is connected with the first end of the resonance coil, the first end of the third capacitor is grounded, the second end of the third capacitor is connected with the second end of the resonance coil, the first end of the switching assembly is connected with the second end of the second capacitor, the second end of the switching assembly is connected with the second end of the third capacitor, and the control circuit is used for controlling on-off of the IGBT and the switching assembly according to user instructions, so that by changing resonance parameters of a resonance circuit, the power range of continuous heating is expanded, and user cooking experience is improved.

Description

Technical field [0001] The invention relates to the technical field of household appliances, in particular to a cooking appliance and an electric heating device for the cooking appliance. Background technique [0002] The related electric heating device can only achieve continuous heating within the preset power range. However, the related technology has a problem that the preset power range is relatively narrow, which cannot meet the needs of users. For example, when the heating power changes within 1000W-1800W, for low-power cooking requirements less than 1000W, low-power heating can only be achieved through intermittent power adjustment, but the cooking effect of intermittent heating is poor and cannot be satisfied User needs; for high-power cooking requirements higher than 1800W, heating can only be continued for a short period of time, such as 3-5 minutes, after a period of time, the maximum power must be forcibly reduced to ensure reliable operation, so that high-power hea...

Problems solved by technology

However, the problem in the related technology is that the preset power range is relatively narrow, which cannot meet the needs of users.

For example, when the heating power changes within 1000W-1800W, for low-power cooking requirements below 1000W, low-power heating can only be realized through intermittent power adjustment. However, the cooking effect of intermittent heating is poor and cannot meet User needs; for high power cooking requirements higher than 1800W, it can only be heated continuously for a short period of time, such as 3-5 minutes. , poor user satisfaction
