Title:
DIRT BLOCKAGE DETECTION METHOD AND APPARATUS, AND PURIFIER, ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/040270
Kind Code:
A1
Abstract:
The present application relates to the technical field of purification device control. Provided are a dirt blockage detection method and apparatus, and a purifier, an electronic device and a storage medium. The method comprises: during operation in a purification mode, acquiring an air output state and a PM2.5 initial concentration Pr, and recording a purification duration Ta of the PM2.5 initial concentration Pr which corresponds to the air output state, wherein the air output state comprises an air output speed and an air output angle; on the basis of the PM2.5 initial concentration Pr, a PM2.5 preset standard concentration Pb and the purification duration Ta, determining a standard purification duration Tb of the PM2.5 preset standard concentration Pb which corresponds to the air output state; determining a clean-state purification duration Tj of the PM2.5 preset standard concentration Pb which corresponds to the air output state, and calculating the difference ΔT between the standard purification duration Tb and the clean-state purification duration Tj; and acquiring a duration difference Tc which corresponds to the air output state, determining that the difference ΔT is greater than or equal to the duration difference Tc, and generating a dirt blockage signal. By means of the present application, a dirt blockage condition is determined by means of a purification duration, and standard conversion is performed under various purification conditions, such that the detection is more intelligent and accurate, and a dirt blockage reminder is given in a more timely manner.
