Automatic-draining hand washing sink system and control method thereof
The invention provides an automatic-draining hand washing sink system. A pressure sensor is mounted at a drain outlet formed in the bottom of the sink; a controller module is used for performing parameter detection and converting into a corresponding water level height value; the water level height value is compared with a set parameter value, and when the water level height value exceeds the set value, the controller module controls a motor arranged at the bottom drain outlet of the sink to rotate forward or reversely, so that the drain outlet can be driven to be opened or closed. According to the automatic-draining hand washing sink system, an infrared sensor is mounted on the sink in a position directly facing a human body, and starts working when a user comes to the sink; when the user leaves, the infrared sensor stops working, and if the infrared sensor does not detect infrared radiation again within a set time range, the drain outlet of the sink is opened and then closed until the water pressure is basically zero, and at this moment, a single chip is led to a low-power standby state. The system is simple in structure, and more flexible in setting the drainage height than the traditional method of forming a hole in the sink; in addition, the water resources can be saved, and meanwhile, the sink does not need to be drained manually and is relatively clean and sanitary.
