Abstract

The invention discloses a method, device and system for adjusting output power of a cooking appliance, and the cooking appliance. The method comprises the following steps of obtaining a first voltageof a power supply grid of the cooking appliance in a standby state; obtaining a second voltage of the power supply grid of the cooking appliance in a stable heating state; and determining whether theoutput power of the cooking appliance needs to be adjusted according to the first voltage and the second voltage. The method provided by the embodiment of the invention enables the cooking appliance to determine whether it is necessary to adjust its own output power according to the voltages of the power supply grid during the working process, so as to reduce the load of the power grid when the load of the power grid is close to overload.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a method, device, system and cooking appliance for adjusting the output power of a cooking appliance. Background technique [0002] When the voltage of the electromagnetic cooking product is below 170V, due to the change of the resonant frequency, the IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) will lag behind the zero point of the resonant voltage when it is turned on, resulting in an increase in the loss of the IGBT switch. The reliability of product operation is reduced. Therefore, electromagnetic cooking products are usually designed for low-voltage protection, that is, the heating is turned off and the low voltage is prompted when it is lower than 170V. However, the grid voltage in many areas of China is often lower than 170V, and the above-mentioned low-voltage protection design will inevitably cause electromagnetic cooking prod...
