Thus, when the socket unit 10 is connected to a plurality of loads through a plurality of output interfaces arranged in parallel, the socket unit 10 may be overloaded and overloaded, and therefore, the current or voltage passing through the socket unit 10 is monitored in real time through the power detection module 14, and the occurrence of fire accidents can be avoided.
In other embodiments of the present invention, as shown in fig. 6, the outlet unit 10 further includes: the temperature sensor 18 and the temperature sensor 18 are connected with the main control module 12, and when the temperature of the socket unit 10 exceeds a preset range, the main control module 12 sends a power-off instruction to the load control module 11, so that the electric energy transmission to the washing electric appliance 200 is completely stopped, and the washing electric appliance 200 is shut down. It can be understood that the temperature of the socket unit 10 may exceed the predetermined value in case of too long usage time or too high summer temperature, and therefore, the real-time temperature detection can effectively avoid the possibility of fire caused by the burning out of the socket unit 10.
In further alternative embodiments of the present invention, as shown in fig. 7, the outlet unit 10 includes: the leakage monitoring module 19 and the leakage monitoring module 19 are connected to the main control module 12, when the leakage monitoring module 19 detects that the leakage current of the washing appliance 200 exceeds the safe range, the main control module 12 sends a power-off command to the load control module 11, and the live wire circuit 202 and the zero wire circuit 201 of the socket unit 10 are respectively disconnected, so that the washing appliance 100 is completely disconnected. For example, the electric leakage caused by the aging or water seepage of the electric wire can be monitored by the electric leakage monitoring module 19, so that the safety accident is avoided. The leakage monitoring module 19 can detect the current or voltage condition of the neutral circuit 202 or the live circuit 201 of the socket unit 10.
Further optionally, when the leakage monitoring module 19 detects that the leakage current of the washing appliance 100 exceeds the safe range, the main control module 12 controls the load control module 11 to disconnect the circuit of the socket unit 10 when the load voltage and/or the current is near a zero crossing point, so as to reduce circuit impact caused by sudden high-voltage and high-current disconnection, reduce problems of contact arcing, sparks, spring plate oxidation and the like, prolong the service life of the socket unit 10, reduce current impact, and further improve the electricity utilization safety.
In other alternative embodiments of the present invention, as shown in fig. 8, the outlet unit 10 further includes: the network connection module 1c is connected to the mobile phone, the gateway, and the cloud platform through the network connection module 1c, so as to remotely control or control the socket unit 10 by voice, for example, remotely control the washing appliance 200 through the mobile phone to perform a washing operation within a predetermined time. The wireless network communication means includes, but is not limited to, technologies such as bluetooth, WiFi, NB-IOT, etc.
Analysis of various working information and data of the outlet unit 10 can also be realized through the network connection module 1 c. When some power parameter is found to be unreasonable, the unreasonable power parameter can be adjusted.
