The air purifier is an electrical product widely used in the life of the current people. The air cleaner functions to filter dust particles and/or organic contaminants such as formaldehyde from the air. One of the disadvantages of the prior art is that: the comfort level of the air purifier needs to be further improved. Specifically, when the air purifier is operated, the air outlet angle is fixed, and the air purifier is easy to blow the human body directly, so that the human body has a cold feeling. In addition, in order to ensure the filtering effect, the air purifier sometimes needs to run at a high speed, and at this time, the noise of the air purifier is large, so that the comfort level of a user is influenced. Therefore, how to improve the comfort level of the air purifier on the basis of considering the purifying effect of the air purifier becomes a technical problem to be solved by the person skilled in the art.

The air purifier 100 of the embodiment of the invention comprises an air purifying module 110, a control module 120, an adjusting module 130, a display module 140 and an induction module 150. The air purification module 110 may include components such as a housing, a fan, a filter screen, and the like. The control module 120 may include a fan control module, a display panel function control module, a feedback adjustment module, and the like. The adjustment module 130 may include a stepper motor for adjusting the vane angle and an outlet guide vane. The display module 140 may display information such as PM2.5 measurement, temperature and humidity measurement, formaldehyde content measurement, screen life value, operating windshield, etc. The sensing module 150 may include a pyroelectric infrared sensor for sensing the acquisition of the user location information L. The ambient air quality value P is acquired by an air quality sensor (not shown).
In the above embodiment, the user position information L refers to position information of the user with respect to the air purifier, and may specifically include: distance information of the user relative to the air purifier and/or angle information of the user relative to the air purifier.
In the above embodiment, the ambient air quality value P is a parameter that characterizes the air quality of the indoor space in which the air cleaner is located. Wherein the ambient air quality value P comprises a content value of PM2.5 in the ambient air and/or a content value of organic pollutants in the ambient air.
It should be noted that, the user position information L and the environmental air quality value P are collected when the air purifier is started. The starting of the air purifier can be the moment when the air purifier is just started, or the moment when the air purifier is started and stably operates. Accordingly, the user location information L and the ambient air quality value P detected and collected at this time are the initial user location information L and the ambient air quality value P, which characterize the location and the ambient air quality of the user at the beginning of the operation of the air purifier.
In the above step S200, the air guiding blade angle α refers to the angle of the air guiding blade at the air outlet of the air purifier, and the angle determines the air output and the air output angle of the air purifier. It is understood that the greater the air output, the higher the air purification efficiency. In addition, the larger the air output, the more obvious the cold feel the user feels at the air outlet.
In the above step S200, the fan gear n refers to a gear of the fan at the air outlet of the air purifier, which determines the air outlet speed of the air purifier. It will be appreciated that the higher the wind output velocity, the higher the air purification efficiency and the greater the noise. In addition, the higher the air outlet speed, the more obvious the cold feel the user feels at the air outlet.
Through the steps S100 to S200, when the air purifier is started, the embodiment of the invention detects the user position information L and the environmental air quality value P of the air purifier, and accordingly controls the air guide blade angle α and the fan gear n of the air purifier according to the user position information L and the environmental air quality value P. Therefore, the embodiment of the invention can enable the wind guide blade angle alpha and the wind turbine gear n of the air purifier to be matched with the actual user position information L and the environmental air quality value P obtained through detection. In other words, the air guide vane angle α and the fan gear n of the air purifier according to the embodiment of the present invention are not fixed, but can be adjusted flexibly according to the actual user position information L and the environmental air quality value P. Therefore, on the basis of considering the purification effect of the air purifier, the embodiment of the invention adjusts the air outlet angle and the air outlet speed of the air purifier according to the position of the user and the air quality so as to achieve the effect of improving the comfort level of the air purifier.
Example 2
The embodiment of the invention provides a control method of an air purifier, and based on the above embodiment, S200 specifically includes:
S210, when the air purifier is started, controlling the angle alpha of the air guide blade to be an initial angle alpha 0, and controlling the gear n of the fan to be an initial gear n 0;
s220, controlling the air guide blade of the air purifier to be kept at an initial angle alpha 0 or to move from the initial angle alpha 0 to a target angle alpha Target object according to the user position information L;
S230, controlling a fan of the air purifier to be directly reduced to a low gear from an initial gear n 0 or to be reduced to the low gear after being increased to a high gear from the initial gear n 0 according to an environmental air quality value P;
The low gear is a gear lower than the initial gear n 0, and the high gear is a gear higher than the initial gear n 0.
The purpose of step S210 is to ensure that the air guiding vane of the air purifier is at a fixed initial position and that the fan gear starts to operate from a fixed initial speed when the air purifier is just started. It can be understood that when the air purifier is started, if the air guiding blade is already at the initial angle alpha 0, the angle is kept unchanged; if the wind guiding vane is not at the initial angle alpha 0, it is rotated to the initial angle alpha 0. Similarly, when the air purifier is started, if the fan is in the initial gear n 0, the gear is kept unchanged, and the air purifier is directly started; if the fan is not in the initial gear n 0, the fan is switched to the initial gear n 0, and is started.
The purpose of implementing steps S220 and S230 is to reasonably control the wind guiding blade and the fan gear of the air purifier. The angle of the air guide blade affects the body feeling of a user, so that the air guide blade of the air purifier can be controlled according to the user position information L. Because the ambient air quality affects the air purification needs of the user, the fan gear of the air purifier can be controlled according to the ambient air quality value P. By the control mode, the air guide blade angle alpha and the fan gear n of the air purifier are further mutually matched with the actual user position information L and the environmental air quality value P, and the comfort degree of the air purifier is further improved.
Example 3
The embodiment of the invention provides a control method of an air purifier, and further comprises the following technical characteristics on the basis of the embodiment.
The air outlet of the air purifier under the initial angle alpha 0 is the upper limit air outlet, and the air outlet of the air purifier under the target angle alpha Target object is smaller than the upper limit air outlet. The air guide vane angles of the air purifier at the initial angle alpha 0 are kept parallel, and the air guide vane angles of the air purifier at the target angle alpha Target object are kept obliquely upwards. The air purifier has at least 5 fan stages, at least 2 of the at least 5 fan stages being lower than an initial stage n 0, and another at least 2 of the at least 5 fan stages being higher than an initial stage n 0.
The upper limit air output of the air purifier refers to the maximum air output of the air purifier. As shown in fig. 4, in order to ensure that the air output of the air purifier is maximum at the initial angle α 0, the air guide vane angles of the air purifier at the initial angle α 0 may be kept parallel, so as to reduce the resistance of the air guide vanes to the air flow. It will be appreciated that the target angle α Target object is different from the initial angle α 0, and the air output of the air cleaner at the target angle α Target object is smaller than the air output at the initial angle α 0.
In other words, the control process of the air guide vane angle of the air purifier according to the embodiment of the invention is a process of keeping the air guide vane angle and the air output constant according to different user position information L or controlling the air guide vane angle to change so as to reduce the air output.
The limitation of the initial angle α 0 and the target angle α Target object in the above technical solution enables the air purifier according to the embodiment of the invention to control the air volume according to different user position information L.
By setting the air purifier to have at least 5 fan gears, and at least 2 fan gears among the at least 5 fan gears are lower than the initial gear n 0, and the other at least 2 fan gears among the at least 5 fan gears are higher than the initial gear n 0, the air purifier provided by the embodiment of the invention can be used for more flexibly adjusting the fan gears according to the environmental air quality value P.
Example 4
The embodiment of the invention provides a control method of an air purifier, and further comprises the following technical characteristics on the basis of the embodiment.
S220 specifically includes:
s221, controlling the air guide blade to be kept at an initial angle alpha 0 under the condition that the user position information L is that no user exists on the front side of the air purifier;
S222, when the user position information L indicates that there is a user on the front side of the air cleaner, the air guide blade is controlled to move from the initial angle α 0 to the target angle α Target object .
In the embodiment of the invention, the air outlet is arranged at the top position of the air purifier. The front side of the air cleaner refers to the side facing the user. As shown in fig. 4, the target angle α Target object may be the first target angle α Target object 1 or the second target angle α Target object 2.
It should be noted that, the target angle α Target object is different from the initial angle α 0, where the air output of the air purifier at the initial angle α 0 is an upper limit air output, and the air output of the air purifier at the target angle α Target object is less than the upper limit air output.
The reason why the embodiment of the invention adopts the scheme is that when the user position information L is that the front side of the air purifier is free of a user, the initial angle alpha 0 can be kept to increase the air output, and when the user position information L is that the front side of the air purifier is provided with the user, the air guide blade can be controlled to move from the initial angle alpha 0 to the target angle alpha Target object so as to reduce the cold feeling of the user.
Example 5
The embodiment of the invention provides a control method of an air purifier, and further comprises the following technical characteristics on the basis of the embodiment.
As shown in fig. 3, the air cleaner 100 includes a first air outlet 160 and a second air outlet 170 that are disposed opposite to and spaced apart from each other. S222 specifically includes:
S222a, controlling the air guide blades with the air outlets of the users at the first air outlet and the second air outlet to move from an initial angle alpha 0 to a first target angle alpha Order of (A) standard 1 under the condition that the user position information L is that the user is located at the front side of the air purifier and the user is located at any one of the first air outlet and the second air outlet;
S222b, controlling the air guide blades at the first air outlet and the second air outlet to move from an initial angle alpha 0 to a second target angle alpha Target object 2 under the condition that the user position information L is the area between the first air outlet and the second air outlet, wherein the user is located on the front side of the air purifier;
As shown in fig. 4, the air output of the air purifier at the second target angle α Target object 2 is greater than the air output at the first target angle α Target object 1.
In the case that the air purifier 100 includes the first air outlet 160 and the second air outlet 170 which are disposed opposite to each other and spaced apart from each other, the air outlet quantity and the air outlet angle of the first air outlet 160 and the second air outlet 170 are reasonably controlled. In the case that the user is located at the front side of the air purifier and is located at the first air outlet 160 or the second air outlet 170, in order to avoid the user feeling cold, the air guiding blades of the air outlets of the user in the first air outlet 160 and the second air outlet 170 can be controlled to move from the initial angle α 0 to the first target angle α Target object 1, so as to achieve the purpose of reducing the air output. In case that the user is located at the front side of the air cleaner and between the first air outlet 160 and the second air outlet 170, the wind guide blades at the first air outlet 160 and the second air outlet 170 may be controlled to move from the initial angle α 0 to the second target angle α Target object 2. It should be noted that, the air output of the air purifier at the second target angle α Target object 2 is greater than the air output at the first target angle α Target object 1, so when the user is located between the first air outlet 160 and the second air outlet 170, the air purifier 100 according to the embodiment of the present invention can increase the air output, so as to ensure the air purifying efficiency on the basis of ensuring the comfort level.
Example 6
The embodiment of the invention provides a control method of an air purifier, and further comprises the following technical characteristics on the basis of the embodiment.
S200 specifically comprises:
S201, when the user position information L is that the front side of the air purifier is not used and the environmental air quality value P is in a first range [ P 0-p1 ], controlling the air guide blade to be kept at an initial angle alpha 0, controlling the fan to keep an initial gear n 0 until the environmental air quality value P reaches a first threshold value M 1 and is maintained for a first time t 1 under the condition of being lower than the first threshold value M 1, and controlling the fan to be lowered from the initial gear n 0 to a first low gear n Low and low 1;
S202, when the user position information L is that the front side of the air purifier is not used and the environmental air quality value P is in a second range [ P 1-p2 ], controlling the air guide blade to be kept at an initial angle alpha 0, controlling the fan to be kept running after being lifted from an initial gear n 0 to a first high gear n High height 1 until the environmental air quality value P reaches a first threshold value M 1, controlling the fan to be kept running after being lowered from the first high gear n High height 1 to a second low gear n Low and low 2 until the environmental air quality value P reaches a second threshold value M 2 and is kept for a second time t 2 under the condition of being lower than the second threshold value M 2, and controlling the fan to be lowered from the second low gear n Low and low 2 to the first low gear n Low and low 1;
s203, when the user position information L is that the front side of the air purifier is not used and the environmental air quality value P is in a third range [ P 2-p3 ], controlling the air guide blade to be kept at an initial angle alpha 0, controlling the fan to keep running after being lifted from an initial gear n 0 to a second high gear n High height 2 until the environmental air quality value P enters a first range [ P 0-p1 ], controlling the fan to be lowered from the second high gear n High height 2 to the initial gear n 0 to keep running until the environmental air quality value P reaches a first threshold M 1, controlling the fan to be lowered from the initial gear n 0 to a second low gear n Low and low 2 to keep running until the environmental air quality value P reaches a second threshold M 2 and keeps a second time t 2 under the condition of being lower than the second threshold M 2, and controlling the fan to be lowered from the second low gear n Low and low 2 to the first low gear n Low and low 1;
Wherein the method comprises the steps of ,M2＜M1＜p0＜p1＜p2＜p3,n Low and low 1＜n Low and low 2＜n0＜n High height 1＜n High height 2.
Illustratively ,M2＝0.2×p0;M1＝0.6×p0;p1＝1.2×p0;p2＝1.5×p0;p3＝1.8×p0.
Illustratively ,n Low and low 1＝0.5×n0;n Low and low 2＝0.8×n0;n High height 1＝1.2×n0;n High height 2＝1.5×n0.
It will be appreciated that in view of M 2＜M1＜p0＜p1＜p2＜p3, therefore, in the case where the user position information L is that the front side of the air cleaner is not used and the environmental air quality value P is within the first range [ P 0-p1 ], the air quality in the space where the user is located is relatively excellent and there is no problem of blowing the user straight, so that the air guiding blade can be controlled to be maintained at the initial angle α 0 to ensure the air output, and the blower can be controlled to be maintained at the initial gear n 0. After the environmental air quality value P is reduced to the first threshold M 1 and maintained for the first time t 1 under the condition of being lower than the first threshold M 1 by the parameter, the air quality at the moment is relatively better, so that the fan can be controlled to be reduced from the initial gear n 0 to the first low gear n Low and low 1, and the purpose of reducing noise is achieved.
Similarly, in the case that the user position information L is not useful on the front side of the air purifier and the environmental air quality value P is within the second range [ P 1-p2 ], the air quality in the space where the user is located is not very ideal but the problem of direct blowing of the user does not exist, so that the air guiding blade can be controlled to be kept at the initial angle α 0 to ensure the air output, and the fan can be controlled to be operated after being lifted from the initial gear n 0 to the first high gear n High height 1 to effectively purify the air. And after the environmental air quality value P reaches the first threshold value M 1, the control fan is reduced from the first high gear n High height 1 to the second low gear n Low and low 2 to keep running. Operating with this parameter until the ambient air quality value P reaches the second threshold M 2 and is maintained below the second threshold M 2 for a second time t 2, the control fan is reduced from the second low gear n Low and low 2 to the first low gear n Low and low 1. In other words, the above-described process is a process of gradually and reasonably lowering the gear of the blower as the air quality increases.
Accordingly, in the case that the user position information L is not useful at the front side of the air cleaner and the environmental air quality value P is within the third range [ P 2-p3 ], the air quality in the space where the user is located is poor but there is no problem of direct blowing the user, so that the air guiding blade can be controlled to be kept at the initial angle α 0 to ensure the air output, and the fan can be controlled to be operated to efficiently purify the air after being lifted from the initial gear n 0 to the second high gear n High height 2. After the environmental air quality value P enters the first range [ P 0-p1 ], the control fan is reduced to an initial gear n 0 from a second high gear n High height 2 and keeps running until the environmental air quality value P reaches a first threshold value M 1, the control fan is reduced to a second low gear n Low and low 2 from the initial gear n 0 and keeps running until the environmental air quality value P reaches a second threshold value M 2 and keeps running for a second time t 2 under the condition of being lower than the second threshold value M 2, and the control fan is reduced to a first low gear n Low and low 1 from a second low gear n Low and low 2.
It will be appreciated that embodiments of the present invention aim to provide a zoned adjustment of the angle of the wind blade and the fan gear according to different user positions (e.g. first zone a, second zone B, third zone C as shown in fig. 3) and different ambient air qualities. Specifically, the air purifier needs to select a fan gear (i.e. air output and air output speed) adapted to the quality of the ambient air according to the quality of the ambient air, and also needs to select an air guide blade angle adapted to the position of the user according to the specific position of the user. Under the condition that the operation parameters or the operation states of the air purifier are mutually matched with the quality of the ambient air and the position of the user, the air purifier can be ensured to be capable of considering the air purification efficiency and the comfort level of the user.
