Embodiment 1

[0033] see figure 1 , the present invention provides a control method of an air cleaner, comprising:

[0034] S100: Turn on the air purifier, and detect air parameters;

[0035] S200: Obtain the detected value P of the air parameter in the initial state 0 and the speed n of the fan of the air cleaner 0 ;

[0036] S300: In the detection value P 0 Less than or equal to the first threshold S 1 In the case of reducing the speed n 0 ; at the detection value P 0 Greater than the first threshold S 1 In the case of increasing the speed n 0 .

[0037] It is worth noting that the air purifier includes: an air purification module, a display module, and an automatic control module; among them, the air purification module includes: a housing, a fan, a filter, and an air outlet grille; the display module includes: PM2.5 display, Temperature and humidity display, formaldehyde content display, filter life display, running windshield display.

[0038] Specifically, the air purifier ...

Embodiment 2

[0042] On the basis of embodiment one, see figure 2 , at the detection value P 0 Less than or equal to the first threshold S 1 In the case of reducing the speed n 0 , including: in the detection value P 0 less than the first threshold S 1 , and the detection value P 0 less than the second threshold S 2 and greater than the third threshold S 3 In the case of reducing the speed n 0 to A 1 ×n 0 ; Wherein, the second threshold S 2 less than the first threshold S 1 , and A 1 less than 1.

[0043] Specifically, the preset first threshold S 1 55μg / m 3 , the preset second threshold S 2 45μg / m 3 , the third threshold S 3 35μg / m 3 , and set the first preset interval as S 3 ~S 2 , namely 35~45μg / m 3 . If the PM2.5 detection value P is turned on after the air purifier is turned on 0 Located in the first preset interval 35~45μg / m 3 , then run the first preset time t in the middle gear 1 , the fan speeds on both sides of the air cleaner are from n 0 adjusted to A ...

Embodiment 3

[0050] On the basis of embodiment one, see figure 2 , at the detection value P 0 Less than or equal to the first threshold S 1 In the case of reducing the speed n 0, also includes: in the detection value P 0 less than the first threshold S 1 , and the detection value P 0 less than the third threshold S 3 and greater than the fourth threshold S 4 In the case of reducing the speed n 0 to A 2 ×n 0 ; where, A 2 less than A 1 .

[0051] Specifically, the preset first threshold S 1 55μg / m 3 , the third threshold S 3 35μg / m 3 , the fourth threshold S 4 0μg / m 3 , and set the second preset interval as S 4 ~S 3 , namely 0~35μg / m 3 . If the air purifier is turned on, the PM2.5 detection value P 0 Located in the second preset interval 0~35μg / m 3 , then run the first preset time t in the intermediate gear 1 , the fan speeds on both sides of the air cleaner are from n 0 adjusted to A 2 ×n 0 .

[0052] Further, the preset set value P s . The air cleaner operate...

Abstract

The invention provides an air purifier control method which comprises the steps that an air purifier is started, and air parameters are detected; the detection value P0 of the air parameter in the initial state and the rotating speed n0 of a draught fan of the air purifier are obtained; under the condition that the detection value P0 is smaller than or equal to the first threshold value S1, the rotating speed n0 is reduced; and under the condition that the detection value P0 is greater than the first threshold value S1, the rotating speed n0 is increased. The technical problem that the air purifier cannot automatically adjust the rotating speed of the fan is solved, and the technical effects that the air purifier can automatically adjust the rotating speed of the fan, the purification efficiency of the air purifier is improved, and energy waste is reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to a control method of an air purifier. Background technique [0002] Since the outbreak of the epidemic, people have higher and higher requirements for indoor air quality. The use of air purifiers can improve indoor air quality, so air purifiers are widely used. [0003] However, there is such a problem: the air purifiers currently on the market cannot automatically adjust the speed of the fan, and it is necessary to manually determine its operating windshield and its operating status to adjust the speed of the fan, resulting in low purification efficiency or energy waste. Contents of the invention [0004] The technical problem solved by the invention is that the air purifier cannot automatically adjust the speed of the fan, and the technical effect achieved is that the air purifier can automatically adjust the speed of the fan, improve the purification efficiency of the a...
