Air purifier, filter screen monitoring method and device of air purifier and storage medium

Abstract

The invention discloses an air purifier, a filter screen monitoring method and device of the air purifier and a storage medium. The filter screen monitoring method of the air purifier comprises the steps that S10, the cleanliness degree y=y0-t / (i / I) / Tn of a filter screen is obtained through calculation, wherein y0 represents the latest recorded cleanliness degree, t represents the starting running time of the time, i represents the air quality improvement rate of set time, I represents the air quality improvement rate of standard set time, Tn represents the available safe working time of the washing interval of the round and Tn conforms to the equation of Tn=T*xn%, T represents the factory safe working time, n represents the washing frequency, and xn% represents the scalage of the washing life; and S12, when the cleanliness degree y is reduced to a set cleaning threshold value, the air purifier is controlled to be turned off, and a user is reminded to wash the filter screen. According to the technological method, it is not need to additionally arrange a detection component to detect the smudge state of the filter screen, moreover, shutdown and user reminding can be automatically achieved according to the cleanliness degree of the filter screen, and the intelligent degree is high.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purifier, its filter screen monitoring method and device, and a storage medium. Background technique [0002] As the most frequently replaced / cleaned part of the air purifier, the filter has always lacked a full life cycle management and control method, and cannot ensure that the purified air is truly purified. If the filter has not been cleaned for a long time, or if it is too dirty, it will not only not purify the air, but will cause secondary air pollution. [0003] Patents "CN 104390322 A" and "CN201510295624.5" use wind speed sensors to detect changes in wind speed, and judge the dirt and blockage of the filter screen through the attenuation rate of wind speed. Compared with the technology before this patent, it solves the dependence on the air quality level, does not need to spend the cost of detecting the air quality, and does not need the user to manually...
