Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Since the start-up current of some fixed-frequency household appliances (such as fixed-frequency air conditioners) is several times the rated current during the start-up phase, the current detection device of the power control module detects the total current value I of the household appliances during the start-up phase of the fixed-frequency air conditioner. Z very large, the total power consumption current value I Z That is, the total current on the home bus, that is, the total electric current value I of all turned-on household appliances in the family Z , if the current detection device of the power control module detects the total electric current I Z Greater than the preset rated current value I 0 (that is, the rated current value I of the air switch 0 ) when the transmitter device of the power control...

Abstract

The invention discloses a control method of a fixed-frequency home appliance, a power control module and a readable storage medium. The control method of the fixed-frequency home appliance comprises the following steps: detecting whether a transmitting device of a power control module has sent a start-up command to a controlled fixed-frequency home appliance and acquiring a total electric currentvalue of the home appliance; if so, stating timing and determining whether a ratio of the total electric current value to a preset rated current value is less than or equal to a preset special start-up threshold within preset timing time; if so, controlling the controlled fixed-frequency home appliance to start up normally for working; and if not, controlling the transmitting device to sent a shutdown command to the controlled fixed-frequency home appliance to control the controlled fixed-frequency home appliance to power off. Therefore, a problem of frequent shutdown of the fixed-frequency home appliance under the limitation of intelligent controlling function of the home electric power is solved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a control method, a power control module and a readable storage medium for fixed-frequency 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 the start-up current of some fixed-frequency home appliances (such as fixed-frequency ai...
