Cooking device control method, cooking device control system and cooking device

Abstract

The invention discloses a cooking device control method, a cooking device control system and a cooking device, wherein the cooking device control method comprises the steps of controlling the resonantfrequency to be increased to the first frequency from the pre-set frequency, so that the optimal resonant working frequency of an ultrasonic oscillator can be searched in the range from the pre-set frequency to the first frequency, wherein the first frequency is less than the upper limit value of a pre-set frequency detection interval; if the first frequency is the optimal resonant working frequency of the ultrasonic oscillator, controlling the resonant frequency to be increased to the second frequency from the first frequency, so that the optimal resonant working frequency of the ultrasonicoscillator can be searched in the range from the first frequency to the second frequency; and, performing ultrasonic cooking at the optimal resonant working frequency, wherein the second frequency isgreater than the first frequency, and less than the upper limit value of the pre-set frequency detection interval. By means of the cooking device control method in the invention, the ultrasonic oscillator can be in the optimal working state; furthermore, the noise is relatively low when the optimal resonant working frequency is searched; and influences of the noise on a user are 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 ...
