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 cooking device control method, system and cooking device. Wherein, the control method of the cooking device includes: gradually reducing the resonant frequency of the resonant module from the upper limit of the interval to the lower limit of the interval within the preset frequency detection interval; detecting the real-time voltage of the resonant module; according to the The real-time voltage determines the optimal resonant operating frequency of the ultrasonic vibrator; ultrasonic cooking is performed at the optimal resonant operating frequency. The control method of the cooking device of the present invention can keep the ultrasonic vibrator in the best working state and improve the working efficiency of the ultrasonic vibrator. In addition, the optimal resonant operating frequency is found within a relatively small frequency detection interval, thereby avoiding large noise when searching for the optimal resonant operating frequency, and has the advantage of relatively small noise when searching for the optimal resonant operating frequency, effectively reducing noise Impact on users.

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 ...
