Air purifying device and control method thereof

Abstract

The invention relates to an air purifying device and a control method thereof. The control method includes: acquiring an air volume value and a noise value; before the noise value is larger than a target noise value, controlling an air supply module according to the air volume value and a first target air volume value to keep the air volume at an air supply port at the first target air volume value; after the noise value is larger than a target noise value, controlling the air supply module according to the noise value and the target noise value to keep noise generated by the air purifying device at the target noise value, and judging whether the air volume value is smaller than a second target air volume value or not; if the air volume value is smaller than the second target air volume value, judging that a filter module loses a filtering function. The air supply volume of the air purifying device can be controlled according to the noise value, constant air supply volume of the air purifying device can be guaranteed as far as possible, noise increasing of the air purifying device is inhibited as far as possible under a high-noise condition while large air supply volume is realized, and accordingly a comfortable living and working environment can be provided for users.

Description

technical field [0001] The invention relates to the field of air treatment equipment, in particular to an air purification device control method and the 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 control method of the air purification device and an air purification device, which can ensure that the air supply volume of the air pu...
