Embodiment 1

[0066] figure 1 The implementation flow of the noise reduction control method for the air purifier provided by the embodiment of the present invention is shown, and the details are as follows:

[0067] S101. Detect air quality information A, and determine an optimal rotational speed V0 of the air purifier according to the air quality information A.

[0068] When detecting the air quality information A, any instrument or device for detecting air quality information provided by the prior art can be used to detect the air quality information, such as equipment using a weighing method, etc., which is not limited here. Among them, the equipment using the weighing method generally obtains the PM value by detecting the weight of dust in a certain volume. Specifically, the equipment using the weighing method can use the light (or laser) scattering method: dust scatter visible light, infrared light or laser light, and the number and weight of dust particles in the air can be calculate...

[0088] S201. Detect air quality information A, and determine an optimal rotational speed V0 of the air purifier according to the air quality information A. The specific process is as described above and will not be repeated here.

[0089] S202. Detect a first ambient noise N1 when the air purifier operates at a first rotational speed V1.

[0090] S203, judging whether the first rotational speed V1 is lower than the optimum rotational speed V0, if yes, execute step S204, otherwise, skip to step S210.

[0091] S204, increasing the air purifier from the first rotating speed V1 to the second rotating speed V2. The increase step is ΔS1, that is, V2=V1+ΔS1.

[0092] S205. Detect the second ambient noise N2 when the air purifier runs at the second rotational speed V2.

Abstract

The invention provides a noise reduction control method and device of an air purifier. The method comprises the following steps: detecting air quality information, and determining an optimal rotary speed of the air purifier according to the air quality information; detecting first environment noises when the air purifier is operated at a first rotary speed; determining a rotary speed change type according to the size relation between the first rotary speed and the optimal rotary speed of the air purifier; detecting second environment noises when the air purifier is operated at a second rotary speed from the first rotary speed according to the change type; and determining an actual operation rotary speed of the air purifier according to whether the first environment noises and the second environment noises are the same or not. According to the noise reduction control method and device of the air purifier, the rotary speed of the air purifier is improved as much as possible when the air purifier is operated at the rotary speed which does not influence the environment noises; the rotary speed of the air purifier is reduced when the air purifier is operated at the rotary speed which influences the environment noises, so that the noises of the air purifier can be reduced, and the output ratio of clean air of the air purifier is improved.

Description

technical field [0001] The invention relates to the technical field of home appliances, and more specifically, to a noise reduction control method and device for an air purifier. Background technique [0002] As the environmental pollution becomes more and more serious, the application of air purifiers becomes more and more extensive. Air purifiers generally include filters, fans, processors, and various sensors for measuring air quality information. The process of the air purifier purifying the air is briefly described as follows: the current air quality information is measured by various sensors used to measure the air quality information, and the processor controls the fan to run at a certain speed according to the air quality information to drive the air flow filter. Dust and other pollutants are absorbed by the filter, so as to achieve the purpose of purifying the air. Generally, the faster the speed of the fan, the better the air purification ability of the air purif...
