Title:
INTELLIGENT TIMER SWITCH
Document Type and Number:
WIPO Patent Application WO/2018/023645
Kind Code:
A1
Abstract:
Provided is an intelligent timer switch (100), comprising a main control circuit (102), an interface circuit (103), a power supply circuit (104), and a display circuit (105). The main control circuit (102) is configured to implement condition-based control of the timer switch (100). The interface circuit (103) is configured to connect an electrical equipment equipped with a compressor, acquire an operating status of the electrical equipment and provide the same to the main control circuit (102), and receive a control signal of the main control circuit (102) to control the on- and off-state of the electrical equipment. The power supply circuit (104) is configured to transform the mains supply voltage into a voltage required by the main control circuit (102), the interface circuit (103), and the display circuit (105). When a time reaches a specified power supply time, the intelligent timer switch (100) is delayed for a period of time and then turns on a relay to supply power to the equipment. Before the time reaches a specified power-off time, the intelligent timer switch (100) detects the operating status of the electrical equipment in advance, disconnects the relay after the compressor is shut down, and powers off the equipment. The intelligent timer switch (100) can regularly switch on and off the electrical equipment, and protect the electrical equipment by performing a determination based on conditions when switching on and off.
