Document Type and Number:
WIPO Patent Application WO/2023/005476
Kind Code:
A1
Abstract:
The present application relates to the technical field of air conditioners. The present application provides a dust accumulation detection method for an air conditioner purification module, an air conditioner, and a storage medium. The air conditioner is provided with an air outlet, a purification module is mounted in an air channel communicated with the air outlet in the air conditioner, and an air deflector is mounted at the air outlet. The detection method comprises the steps of: controlling a fan in the air channel to operate at a set rotating speed, and obtaining a first detection sound spectrum and a first reference sound spectrum at the air outlet when the air deflector is located at a first set position; and determining a current first dust accumulation state of the purification module according to a degree of fitting between the first reference sound spectrum and the first detection sound spectrum. The first set position corresponds to a position where the air deflector will make abnormal sound when the purification module is in a set dust accumulation state; the first reference sound spectrum corresponds to a sound spectrum at the air outlet when the purification device is in the set dust accumulation state. By means of the detection method, the dust accumulation state of the purification module can be determined accurately.
