Abstract

The invention discloses an alternating-current load control module. The control module includes at least one electronic control switch. Each electronic control switch has a first electric input end, afirst electric output end and a control signal input end, the first electric input end of each electronic control switch is directly or indirectly connected with a firewire of an alternating-current-power-supply bus through a power-supply wire, the first electric output end of each electronic control switch is directly connected with the first electric connection end of one alternating load through a power-supply wire, and the control signal input end of each electronic control switch is directly connected with one control signal source through a signal wire. According to the control signal input from the control signal input end, the first electric input end and the first electric output end of each electronic control switch are electrically connected or cut off. According to the alternating-current load control module, the type, number and position of each electronic control switch in an alternating-current load control module can change along with the change of the type, number andposition of the alternating load, and therefore, the whole alternating-current load control module is good in expansibility and popularity.

Description

technical field [0001] The invention relates to a control module suitable for controlling the power supply of AC loads in electrical equipment. Background technique [0002] In the prior art, the control systems of home appliances (such as washing machines, refrigerators, etc.) mostly adopt centralized control systems, that is, there is only one controller, and all peripheral execution components and / or sensing components (such as valves, sensors, motors, etc.) are directly connected to this controller. For this centralized home appliance control system, all control switches and sensor circuits are integrated on the main control board, and are connected to all loads in a star-shaped direct connection. For some components with complex control and concentrated functions, such as variable frequency motors and user display and control interfaces, modules are usually used to communicate through serial ports. The modules themselves follow the star connection according to their f...
