Problems solved by technology

[0003] Therefore, the pollution is relatively serious, so the service life of the filter screen in the existing air purifier is not too long, and it needs to be replaced frequently. The frequency of replacing the filter screen in the existing air purifier is completely based on user experience, and there is no quantitative control method. The replacement of the filter itself is related to the pollution concentration. The pollution concentration varies greatly every day, and it is difficult to determine the replacement time of the filter by experience; A Quantitative Filter Replacement Reminder Method

Abstract

The invention relates to the field of small household appliances, in particular to a direct quantitative control method for indoor air purifier filter screen replacement. According to the direct quantitative control method for indoor air purifier filter screen replacement, a mass threshold value is set, and then controlling is conducted through the following steps that after a filtering assembly is installed, the initial weight of the filtering assembly is obtained through a weight sensor, when a filter starts working, a controller obtains the current weight of the filtering assembly by reading the weight sensor in real time, the filtrate weight is obtained by subtracting the initial weight from the current weight, and when the filtrate weight exceeds the mass threshold value, the controller controls an alarming mechanism to give an alarm. According to the method, the weight of particulate matter attached to a filter screen is obtained by monitoring the weight added value of the filtering assembly in real time, when the weight of the attached particulate matter exceeds the mass threshold value, the filter screen needs to be replaced, therefore, quantitative control over filter screen replacement is achieved, the replacement cycle of the filter screen reaches the maximum value while the filtering efficiency is guaranteed, and the method is more beneficial for being used by an ordinary family.

Description

technical field [0001] The invention relates to the field of small household appliances, in particular to a quantitative control method for replacing filter screens of indoor air purifiers. Background technique [0002] China's air pollution is getting worse and worse. At the beginning of December 2015, nearly half of China's territory experienced haze weather in varying degrees. The national average number of haze days has exceeded 50 days, seriously affecting human health. Therefore, in heavily polluted cities, every household Every household needs an indoor air purifier. [0003] Therefore, the pollution is relatively serious. Therefore, the service life of the filter screen in the existing air purifier is not too long, and it needs to be replaced frequently. The frequency of replacing the filter screen in the existing air purifier is completely based on user experience, and there is no quantitative control method. The replacement of the filter itself is related to the p...
