Power supply control system for washing electric appliance

Abstract

The invention discloses a power supply control system for a washing electric appliance, which comprises a socket unit. The socket unit at least comprises: a socket unit, the system comprises a load control module, a main control module, a first wireless communication module and an electric energy detection module. Wherein the electric energy detection module, the load control module and the firstwireless communication module are electrically connected with the main control module; the electric energy detection module transmits monitoring information to the main control module; when the electric energy detection module monitors that the power loaded by the washing electric appliance is lower than a preset value and lasts for a preset time, the main control module sends a power-off instruction to the load control module, and the load control module disconnects a zero line circuit and a live line circuit of the socket unit after receiving the power-off instruction so as to stop transmitting electric energy to the washing electric appliance. And the remote controller at least comprises a second wireless communication module, a user-defined module and a power supply module. According to the power supply control system for the washing electric appliance, the power utilization safety is improved, the service life is long, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a power control system for washing appliances. Background technique [0002] With the continuous progress and development of society, more and more washing appliances are used in daily life, such as drum washing machines, wave wheel washing machines, clothes dryers, dishwashers and washing and drying machines, etc. In order to save space in home decoration, Ensure that the overall decoration style is consistent. Washing appliances are usually installed in the dark, and it is very inconvenient to plug and unplug the plugs and sockets. That is to say, the power supply of washing appliances cannot be turned off at any time. The circuit and some components will be in a charged state, which consumes the life of the components.

Problems solved by technology

[0002] With the continuous progress and development of society, more and more washing appliances are used in daily life, such as drum washing machines, wave wheel washing machines, clothes dryers, dishwashers and washing and drying machines, etc. In order to save space in home decoration, Ensure that the overall decoration style is consistent. Washing appliances are usually installed in the dark, and it is very inconvenient to plug and unplug the plugs and sockets. That is to say, the power supply of washing appliances cannot be turned off at any time. The circuit and some components will be in a charged state, which consumes the life of the components

[0003] The washing and drying power of drum washing machines, dishwashers and all-in-one washing and drying machines is relatively high. Generally, the power lines of the above-mentioned washing appliances are directly connected to the mains, which is beyond the safety threshold voltage of the human body. However, during the use of washing appliances, they are often artificially The degree of participation is high. For example, when washing clothes, you must first put the clothes into the washing tub. After washing the clothes, you need to take out the clothes that are not completely dry from the washing tub; The dishes are placed in the washing basket, and the dishes need to be taken out after washing

That is to say, the existence of water will cause a potential leakage path in the abnormal condition of the washing appliance, and it is easy for people to cause harm during operation. Therefore, during the frequent contact between the user and the washing appliance, if there is a problem of strong current leakage, a safety accident will occur. Bodily injury, severe death

[0004] Furthermore, it is understandable that a washing machine that is on standby and not disconnected from the power supply can easily be restarted, at which point a child would be a huge personal injury problem if they got into the tub and were restarted

[0005] In addition, some users may have the problem of no grounding wire or irregular grounding wire when wiring the mains power line in some users' homes. The position of the live line is connected to the neutral line. In this way, in the event of a dangerous situation, when only cutting off the so-called "fire line" may become a false cut off of the "zero line", the "fire line" is still connected. The so-called disconnected state still poses a risk of electric shock

[0006] In short, the work of washing appliances must be carried out under the condition of strong electricity, but it is also affected by the installation environment. After the work is stopped, the power cannot be completely cut off and shut down in time, resulting in a large safety hazard in the use of washing appliances, which needs to be improved urgently.
