[0051] refer to image 3 , image 3 It is a schematic flowchart of the second embodiment of the air purifier control method of the present invention. Based on the first embodiment of the above method, the step S30 includes:

[0052] Step S31, calculating the running time difference between the accumulated running time and a preset threshold;

[0053] Step S32, determining the alarm level corresponding to the operating time difference, and sending out the alarm information of the particle adsorption device corresponding to the alarm level.

[0054] In the above embodiment, as long as the cumulative operating time is greater than or equal to the preset threshold, an alarm message of the particle adsorption device 103 is issued to prompt replacement or cleaning of the particle adsorption device 103 . The difference between this embodiment and the above-mentioned first embodiment is: when the total effective running time value TTA of the air cleaner 100 is higher than the purif...

Abstract

The invention discloses an air purifier control method and device. An air purifier comprises a particulate matter adsorption device and a particulate matter sensor. The method comprises steps as follows: the particulate matter sensor is used for detecting current particulate matter concentration and determining a particulate matter weight value corresponding to the current particulate matter concentration and an air speed weight value corresponding to a current fan rotating speed in an operating process of the air purifier; time duration of single operation of the air purifier is calculated according to the current particulate matter concentration, the particulate matter weight value and the air speed weight value, and accumulative operating time duration of the air purifier is calculated according to the calculated time duration of single operation every time; when the accumulative operating time duration is larger than a preset threshold, a warning message of the particulate matter adsorption device is sent out. According to the air purifier control method and device, the state of the particulate matter adsorption device is detected automatically, and more accurate prompt for replacing or cleaning the particulate matter adsorption device is provided, so that the particulate matter adsorption device is replaced or cleaned accurately and reasonably.

Description

technical field [0001] The invention relates to the technical field of air purification treatment, in particular to an air purifier control method and device. Background technique [0002] With conventional air purifiers, users do not know when to replace the filter, or they forget to clean the electrostatic adsorption device inside the air purifier. Many times, the filter screen is very dirty, and the air purifier basically does not have the function of purifying particulate matter in the air, and the filter screen is still forgotten; or, because the indoor air itself is very good, the air purifier has not yet reached the standard that needs to be replaced. The user replaces the filter screen prematurely, resulting in an increase in user cost and a waste of resources. [0003] To sum up, at present, the replacement of the filter screen of the air purifier is based on the user's wishes, which makes the timing accuracy of the filter screen replacement poor. [0004] The abo...
