Problems solved by technology

[0002] For cooking devices using ultrasonic cooking technology, such as cooking appliances with cooking cavities inside such as electric rice cookers and electric pressure cookers, and ultrasonic heating devices containing ultrasonic vibrators, due to deviations in processing and assembly, the natural vibration frequency of each vibrator may vary. , there will be a deviation from the fixed frequency, and it will not work in the best state, resulting in low work efficiency. It is necessary to find the best working frequency by changing the working frequency of the ultrasonic vibrator. However, when changing the working frequency, the ultrasonic vibrator Loud noise at some frequencies, causing user discomfort and complaints

Abstract

The invention discloses a control method and system of a cooking device, and the cooking device. The control method of the cooking device comprises the following steps of gradually reducing resonancefrequency of a resonant module from a range upper limit to a range lower limit in a preset frequency detection range; detecting real-time voltage of the resonant module; determining the optimal resonant working frequency of an ultrasonic resonator according to the real-time voltage; and performing ultrasonic cooking according to the optimal resonant working frequency. Through the control method ofthe cooking device disclosed by the invention, the ultrasonic resonator can be located in the optimal working state, and the working efficiency of the ultrasonic resonator is improved. The optimal resonant working frequency is searched in the relatively small frequency detection range, thereby avoiding the large noise produced when the optimal resonant working frequency is searched; and the control method has the advantage of small noise when the optimal resonant working frequency is searched, and the influence on a user by the noise is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a control method and system for a cooking device and the cooking device. Background technique [0002] For cooking devices using ultrasonic cooking technology, such as cooking appliances with cooking cavities inside such as electric rice cookers and electric pressure cookers, and ultrasonic heating devices containing ultrasonic vibrators, due to deviations in processing and assembly, the natural vibration frequency of each vibrator may vary. , there will be a deviation from the fixed frequency, and it will not work in the best state, resulting in low work efficiency. It is necessary to find the best working frequency by changing the working frequency of the ultrasonic vibrator. However, when changing the working frequency, the ultrasonic vibrator Loud noises are generated at some frequencies, causing discomfort and complaints to the user. Contents of the invention ...
