Control method and system of dust removal device for air conditioning filter screen

Abstract

The invention discloses a control method and system of a dust removal device for an air conditioning filter screen, and relates to the technical field of an air conditioner. The control method comprises the following steps that step S1, the filter screen is arranged at an air inlet of a centrifugal fan; step S2, a pressure sensor is fixedly arranged at the edge of the filter screen; step S3, whenthe centrifugal fan works, the numerical value obtained by the pressure sensor exceeds a preset threshold value; step S4, a motor is driven to control a dust sweeping brush to rotate on the surface ofthe filter screen; step S5, the swept dust is sucked into a dust collecting box from a dust guide chamber; and step S6, the operation is carried out until the numerical value collected by the pressure sensor returns to a normal value. The control method is provided with the filter screen at the air inlet of the centrifugal fan and uses the pressure sensor to monitor wind resistance on the filterscreen to judge the degree of blockage of the filter screen, thus starting a dust sweeping brush to sweep the filter screen. The control method monitors the air conditioning filter screen in real time, and thus the cooling efficiency of an air conditioner is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a control method and system for an air conditioner filter dust removal device. Background technique [0002] At this stage, fresh air conditioners are gradually entering the market. Due to their small internal structure space, the volume of the internal purification filter is smaller. Therefore, the dust holding capacity of the purification filter is very low, that is, after long-term use, the purification filter It is easy to be blocked by dust and particles, which increases the wind resistance of the purification filter and reduces the fresh air volume of the air conditioner. [0003] For the clogging of the fresh air air conditioning purification filter, the conventional processing method is to remind the user in a timing manner, so that the user can clean the purification filter in time; this timing reminder method, if the user does not use it for a long ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a control method and system for an air conditioner filter dust removal device. By installing a filter at the air outlet of the centrifuge and using a pressure sensor to monitor the wind resistance on the filter to determine the degree of clogging of the filter, start the process. The dust brush cleans the filter screen, which solves the problem that the existing air conditioning filter screen cannot be monitored and needs to be cleaned manually
