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: controlling the resonant frequency to increase from the predetermined frequency to the first frequency, so as to find the optimum resonant working frequency of the ultrasonic vibrator within the predetermined frequency to the first frequency, wherein the first frequency is less than the preset The upper limit value of the frequency detection interval; if the first frequency is the optimum resonant operating frequency of the ultrasonic vibrator, then control the resonant frequency from the first frequency to the second frequency to increase to find the ultrasonic wave within the first frequency to the second frequency Optimal resonant operating frequency of the vibrator; ultrasonic cooking is performed at the optimal resonant operating frequency, wherein the second frequency is greater than the first frequency and less than the upper limit of the preset frequency detection interval. The control method of the cooking device of the present invention can keep the ultrasonic vibrator in the best working state, and when searching for the best resonant working frequency, the noise is relatively small, which effectively reduces the impact of noise 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 ...
