Title: METHOD AND SYSTEM FOR DETECTING CONCENTRATION OF INDOOR AIR DUST PARTICLES AND HOUSEHOLD APPLIANCE
Abstract:
Disclosed are a method for detecting the concentration of indoor air dust particles, a system (100) for detecting the concentration of indoor air dust particles, and a household appliance (1000) having the system. The detection method comprises: acquiring the degree of dirt blockage of a dust filter screen of the household appliance (1000), and obtaining the rate of change of the dirt blockage in accordance with the degree of dirt blockage of the dust filter screen (S1); and calculating and displaying the corresponding concentration of indoor air dust particles in accordance with the rate of change of the dirt blockage (S2). In the method for detecting the concentration of indoor air dust particles, the concentration of indoor air dust particles is provided for a user, so that the user can be informed in time. The method is easy to implement, and can reduce the cost of air detection.
