Control method of variable frequency household electric appliances, power control module and readable storage medium

Abstract

The invention discloses a control method of variable frequency household electric appliances, a power control module and a readable storage medium. The control method comprises following steps of detecting whether an emission device of the power control module sent a turning-on command to controlled variable frequency household electrical appliances; if detecting that the emission device of the power control module sent the turning-on command to the controlled variable frequency household electrical appliances, acquiring the total electricity utilization current value of the household appliances, detecting the ratio of the total electricity utilization current value of the household appliances to a preset rated current value and starting timing when the ratio of the total electricity utilization current value of the household appliances to the preset rated current value reaches a standard threshold; and according to timing time and the relation of the ratio of the total electricity utilization current value of the household appliances to the preset rated current value, controlling the emission device of the power control module sent the turning-on command to the controlled variablefrequency household electrical appliances so as to control the controlled variable frequency household electrical appliances to be turned off or be turned on continuously to work. According to the invention, a phenomenon that the variable frequency household electric appliances are turned off without disconnection can be avoided and user experience is improved.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a control method, a power control module and a readable storage medium for frequency conversion household appliances. Background technique [0002] At present, in some underdeveloped areas, due to the relatively backward national grid infrastructure, it is necessary to limit the current situation of household power consumption (that is, limit the total household power consumption current value). If the total household power consumption exceeds the limited power value, it will cause The phenomenon that the air switch (also called air circuit breaker) is disconnected. The air conditioner is a high-power electrical appliance in the home. If the air conditioner is turned on during the time when other household appliances in the home are turned on, the air switch may be disconnected. [0003] Since variable frequency home appliances (such as variable frequency air condi...

Problems solved by technology

[0003] Since variable frequency home appliances (such as variable frequency air conditioners) need to increase the frequency to a threshold value at the start-up stage, and then perform other functions, the current of the variable frequency home appliance will become larger and larger during this process, that is, the current detection of the power control module during this process The device detects that the total power consumption current value of household appliances will become larger and larger. When the total power consumption current value is greater than the rated current value of the air switch in the home, the transmitter of the power control module will send a shutdown command to the controlled frequency conversion For household appliances, the final control result is that the controlled frequency conversion household appliances are constantly switched on and off, which makes the power control module lose the function of intelligently adjusting household power consumption, and makes the controlled frequency conversion household appliances unusable, such as the frequency conversion air conditioner. User experience is poor
