Household electrical appliance detection protection method, intelligent socket for household electrical appliances, and washing machine

Abstract

The invention relates to the household electrical appliance field and particularly relates to a household electrical appliance detection protection method, an intelligent socket for household electrical appliances and a washing machine. The method comprises steps that, S10, a voltage value and a current value of a household electrical appliance are detected by a line detection device in real time, and a power is calculated according to the voltage value and the current value; S20, when the household electrical appliance starts, a power curve is drafted by a controller and is further stored, the acquire power curve is matched with a characteristic power curve stored in a database through searching, if matching succeeds, and the type of the household electrical appliance is set to be a household electrical appliance type corresponding to the characteristic curve; and S30, the intelligent socket is set to be in a corresponding work mode according to the household electrical appliance type, when the voltage value Ut, the current value It and / or a real-time power Pt are not in a preset safety scope corresponding to the set work mode, electrical protection for the household electrical appliance is carried out by the intelligent socket. Through the method, the type of the household electrical appliance can be automatically identified, and corresponding detection control strategy is adopted according to the type of the household electrical appliance.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a detection and protection method for household appliances, an intelligent socket for household appliances and a washing machine. Background technique [0002] With the improvement of people's living standards, home appliances with different functions have gradually become an indispensable configuration in people's homes. While meeting daily use, people have higher and higher requirements for the safety and convenience of home appliances. Existing smart sockets can be connected in series between home appliances and power sources to detect power information and control the power on and off of home appliances. They can only detect whether home appliances are powered on and off and actively control their power on and off, but cannot automatically identify them The type of home appliance, and adopt the corresponding detection and control strategy according to the type of home appl...

AI Technical Summary

Problems solved by technology

[0005] Based on the above description, a new home appliance detection and protection method is urgently needed to solve the problem that the smart socket in the prior art cannot automatically identify the type of home appliance, nor can it adopt a corresponding detection and control strategy according to the type of home appliance
