Problems solved by technology

[0002] At present, the air purification device, as a commonly used purification equipment in every household, will be in a long-term working state in daily life. After a long period of continuous use, the particles in the air will deposit on the consumables, which will cause the resistance of the consumables to increase. After the resistance increases, it will As a result, the air volume of the air purification device becomes smaller and cannot achieve the effect of clean indoor air

Embodiment Construction

[0027] figure 1 is a schematic flow chart of a noise-based control method for an air cleaning device according to an embodiment of the present invention. Such as figure 1 As shown, the embodiment of the present invention provides a noise-based control method for an air cleaning device. The air cleaning device may include an air supply port, a filter module, an air supply module, an air volume detection module and a noise detection module. The air supply module is configured to encourage the air to flow to the air supply port after being filtered by the filter module. The air volume detection module is configured to detect the air volume at the air outlet. The noise detection module is configured to detect noise generated by the air cleaning device. The filter module is preferably a filter screen, and the air supply module is preferably a fan. Among them, the noise-based control method of the air purification device may include:

Abstract

The invention relates to a noise-based control method for an air purification device and an air purification device. Specifically, the control method includes: using the noise detection module to detect the noise generated by the air purification device to obtain the noise value; and using the air volume detection module to detect the air volume at the air outlet to obtain the air volume value; after the noise value is greater than the target noise value for the Nth time , control the air supply module according to the air volume value and the Nth target air volume value, so that the air volume at the air supply port remains at the Nth target air volume value, N is a natural number greater than or equal to 1; and when N is greater than 1, the Nth target The air volume value is less than the N‑1th target air volume value. The air supply volume of the air purification device can be controlled according to the noise value, which can ensure a constant air supply volume of the air purification device as much as possible, and can make the noise generated by the air purification device lower, providing users with a comfortable living and working environment.

Description

technical field [0001] The invention relates to the field of air treatment equipment, in particular to a noise-based control method for an air purification device and an air purification device. Background technique [0002] At present, the air purification device, as a commonly used purification equipment in every household, will be in a long-term working state in daily life. After a long period of continuous use, the particles in the air will deposit on the consumables, which will cause the resistance of the consumables to increase. After the resistance increases, it will As a result, the air volume of the air purification device becomes smaller, and the effect of cleaning the indoor air cannot be achieved. Contents of the invention [0003] The present invention aims to overcome at least one defect of the existing air purification device, and provides a noise-based control method for the air purification device and an air purification device, which can ensure that the a...
