[0002] The indoor unit of an air duct machine with upper and lower air outlets is an indoor unit of an air conditioner that changes the air supply direction through a volute, and the air outlet is a device that controls the air supply direction of the air outlet when the air duct machine supplies air. In addition to completing the function of air supply, when the air outlet at the other end discharges air, it also needs to be used as an air intake device. Therefore, the air outlet also needs to have a filtering function. The switching between air intake and air supply of the air outlet involves the adsorption and blowing out of dust on the filter screen. Due to the influence of upper and lower air outlets, the filter screen will adsorb dust during air intake, and if the filter screen and the air deflector do not cooperate well during air supply, the dust on the filter screen will be blown into the room.

[0003] Regarding the problem of how to avoid the dust adsorbed on the filter screen of the air outlet from being blown into the room in the prior art, no effective solution has been proposed yet. Summary of the Invention

[0019] Furthermore, if the changing trend is that the wind speed is lowered, the filter and the air guide plate are adjusted cyclically in sequence according to the preset order based on the calculated data, including: first reducing the filter opening angle according to the single angle adjustment amount of the filter, and then reducing the air guide plate opening angle according to the single angle adjustment amount of the air guide plate, and the cycle is repeated until the filter is adjusted to the filter opening angle corresponding to the changed wind speed, and the air guide plate is adjusted to the air guide plate opening angle corresponding to the changed wind speed.

[0020] Furthermore, if the changing trend is an increase in the wind speed, the filter and the air guide plate are cyclically adjusted in sequence according to the preset order based on the calculated data, including: first increasing the opening angle of the air guide plate according to the single angle adjustment amount of the air guide plate, and then increasing the opening angle of the filter according to the single angle adjustment amount of the filter, and the cycle is repeated until the air guide plate is adjusted to the air guide plate opening angle corresponding to the changed wind speed, and the filter is adjusted to the filter opening angle corresponding to the changed wind speed.

[0044] The optional embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Embodiment 1

[0046] The dust-proof control method of the present invention is applied to the air outlet assembly. The structure of the air outlet assembly at the air outlet will be introduced below. Figure 1 is a schematic side view of the air outlet assembly according to an embodiment of the present invention, as Figure 1 shown, the air duct is the thick dotted line part, which is connected to the filter screen and can intake and exhaust air. The filter screen and the air deflector are controlled by a stepping motor connected by respective drive shafts below. The filter screen is arranged on the air outlet frame through the first drive shaft, and the air deflector is arranged on the air outlet frame through the second drive shaft. There are limit devices ( Figure 1 limit 1 and limit 2 in

[0047] Figure 2 is a schematic view of the air outlet assembly in the open air intake state according to an embodiment of the present invention, as Figure 2 shown, when intaking air, the filter screen is closed (in a vertical state) to filter dust in the air to achieve a better filtering effect on the intake air, and the air deflector is opened at a certain angle to ensure smooth air intake.

[0048] When the air outlet assembly finishes intaking air, dust will be adsorbed on the outer side of the filter screen, and this surface is called the dust-accumulating surface. When switching to the air supply state, the air duct of the air outlet blows air outwards. At this time, if the angle between the air deflector and the filter screen is too large, the dust on the filter screen will be blown back into the room. During the operation of the unit, since it is necessary to avoid directly blowing air towards the user at the air outlet, the angles of the air deflector and the filter screen will be adjusted, which inevitably causes the angles of the filter screen and the air deflector to change, making it possible for the dust to be blown into the room.

[0049] Figure 3 is a schematic view of the air outlet assembly in the open air exhaust state according to an embodiment of the present invention, as Figure 3 shown, taking the axial plane (the plane where the first drive shaft and the second drive shaft are located) as the reference plane, both the filter screen and the air deflector are opened at a certain angle relative to the above-mentioned axial plane to ensure smooth air exhaust. During this process, the angles at which the filter screen and the air deflector are opened relative to the axial plane are crucial and will directly affect whether the dust on the dust-accumulating surface is blown into the room when exhausting air.

[0050] Figure 4 is a schematic diagram of the angle of the air outlet component in the open air outlet state according to an embodiment of the present invention. As Figure 4 shown, θ1 is the angle of the air deflector relative to the shaft plane (i.e., the opening angle of the air deflector), θ2 is the angle of the filter screen relative to the shaft plane (i.e., the opening angle of the filter screen), and θ is the reset angle. The present invention aims to provide a dust prevention control scheme so that the air deflector and the filter screen can adjust their respective opening angles according to functional requirements, and control the opening angles and the angle adjustment speeds of the air deflector and the filter screen during the process of adjusting their respective startup angles, to avoid the situation of blowing dust into the room.

[0051] Embodiment 2

[0052] According to an embodiment of the present invention, an embodiment of a dust prevention control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0053] Figure 5 is a flowchart of the dust prevention control method according to an embodiment of the present invention. As Figure 5 shown, the method includes the following steps:

[0054] Step S501, after the unit is powered on and reset, obtain the wind gear corresponding to the fan speed; wherein, there is a preset corresponding relationship between different wind gears and the opening angles of the filter screen and the air deflector, and the opening angle of the filter screen corresponding to each wind gear is always greater than the opening angle of the air deflector.

[0055] The opening angle of the filter screen is the angle between the filter screen and the shaft plane, and the opening angle of the air deflector is the angle between the air deflector and the shaft plane; the shaft plane is the plane where the first transmission shaft and the second transmission shaft are located. In this embodiment, setting the opening angle of the filter screen corresponding to each wind gear to be always greater than the opening angle of the air deflector is to consider how to avoid the dust on the dust accumulation surface from being blown into the room as much as possible. Refer to Figure 3 that the installation position of the air deflector is outside the installation position of the filter screen, so the opening angle of the filter screen is set to be always greater than the opening angle of the air deflector.

[0056] This embodiment can be set such that: the greater the wind gear, the greater the corresponding opening angles of the filter screen and the air deflector, so as to ensure effective air inlet and outlet; it can also be set that: the greater the wind gear, the smaller the angle difference between the corresponding opening angles of the filter screen and the air deflector, so as to effectively reduce the dust blown out from the dust accumulation surface.

[0057] Step S502, control the filter screen to rotate to the opening angle of the filter screen corresponding to the wind gear, and control the air deflector to rotate to the opening angle of the air deflector corresponding to the wind gear.

[0058] Step S503, when it is detected that the wind gear has changed, the single angle adjustment amount of the filter and the single angle adjustment amount of the air guide plate are calculated, and the filter and the air guide plate are adjusted in a cyclic manner in a preset order according to the calculated data. That is, in this embodiment, the filter and the air guide plate are adjusted in a preset order, and only the single angle adjustment amount of one filter / single angle adjustment amount of the air guide plate is adjusted each time, and then the cycle is repeated accordingly, so that the angle adjustment speed of the filter and the air guide plate can be controlled to achieve a more accurate angle adjustment, and by controlling the angle adjustment speed, the dust on the dust accumulation surface can be effectively prevented from being blown up during the angle adjustment process.

[0059] The present invention takes into account that the air guide plate and the filter need to adjust their own angles when the air outlet is blowing out. In this process, the opening angle and angle adjustment speed of the air guide plate and the filter are controlled. On the basis of not increasing the hardware cost and not affecting the normal operation of the air guide plate and the filter of the air outlet, the dust adsorbed on the filter is effectively prevented from being blown into the room, and it is ensured that the air guide plate and the filter will not blow out dust at any opening angle. In addition, the above adjustment scheme can prevent dust from being blown out of the air outlet without relying on high-precision control equipment and complex control methods, thus saving costs.

[0060] This embodiment performs a power-on reset before the unit is turned on and reset. When the unit is powered on and reset, the filter is first controlled to rotate to a preset filter reset angle, and then the air guide plate is controlled to rotate to a preset air guide plate reset angle. Taking into account that the transmission ratios of the filter and the air guide plate are different during movement, it is necessary to avoid interference between the filter and the air guide plate during movement. The air guide plate is set on the outside of the filter. Based on this, this embodiment controls the filter first and then controls the air guide plate to move to the limit switch position, that is, both are adjusted to the reset angle θ (that is, the above-mentioned preset filter reset angle and the above-mentioned preset air guide plate reset angle). Preferably, the reset angle θ can be set to 40°. If Figure 1 As shown, the angle between the filter and the air guide plate and the axial plane is the reset angle, that is, the reset angle is the angle between the filter and the air guide plate and the axial plane when both are in a vertical state. Generally, the reset angle θ can be set to 40°. In this state, dust is not easily accumulated on the dust accumulation surface.

[0061] After completing the power-on reset operation, perform the power-on reset operation. After receiving the unit power-on signal, considering that the setting position of the air guide plate is outside the setting position of the filter, first control the air guide plate to rotate to the preset air guide plate maximum angle θm1, and then control the filter to rotate to the preset filter maximum angle θm2. In order to reduce the dust blowing out of the dust accumulation surface and reduce the dust falling on the dust accumulation surface, the preset filter maximum angle θm2 can be set to be slightly larger than the preset air guide plate maximum angle θm1. Preferably, it is determined experimentally that when θm1 is set to 130° and θm2 is set to 132°, dust will not be blown out of the dust accumulation surface.

[0062] After the unit completes the power-on reset operation and the startup reset operation, and at this time both the filter screen and the air deflector are adjusted to the target positions, the unit operation control stage can be executed. It is necessary to confirm whether the unit enables the anti-direct-blow function; if not, the filter screen is maintained at the preset maximum filter screen angle, and the air deflector is maintained at the preset maximum air deflector angle; if so, the air duct corresponding to the fan speed is triggered to be obtained. That is, after the anti-direct-blow function is enabled, in this embodiment, the above steps S502 and S503 are executed. First, the filter screen is controlled to rotate to the filter screen opening angle corresponding to the air duct, and the air deflector is controlled to rotate to the air deflector opening angle corresponding to the air duct, and then it is detected whether the fan speed changes, that is, whether the air duct changes.

[0063] When it is detected that the air duct changes, considering that the air duct will gradually increase or decrease (for example, from gear 2 to gear 4), therefore, first calculate the single-angle adjustment amount of the filter screen and the single-angle adjustment amount of the air deflector when increasing (or decreasing) one air duct (for example, from gear 2 to gear 3), and adjust the filter screen and the air deflector in sequence according to the calculated data in a preset order in a loop, and then calculate the single-angle adjustment amount of the filter screen and the single-angle adjustment amount of the air deflector when increasing (or decreasing) the next air duct (for example, from gear 3 to gear 4), and adjust the filter screen and the air deflector in sequence according to the calculated data in a preset order in a loop. Based on this, the angle adjustment speed of the filter screen and the air deflector can be effectively controlled, ensuring small-amplitude movements of the filter screen and the air deflector, and effectively avoiding blowing out dust during the movement of the filter screen or the air deflector. The following is a specific introduction.

[0064] Preferably, calculating the single-angle adjustment amount of the filter screen and the single-angle adjustment amount of the air deflector includes: calculating the single-angle adjustment amount of the filter screen and the single-angle adjustment amount of the air deflector according to the corresponding relationship between the preset air duct and the filter screen opening angle and the air deflector opening angle, and the air ducts before and after the change; wherein, the single-angle adjustment amount is the single-angle adjustment amount when increasing or decreasing one air duct. Thus, small-amplitude movements of the filter screen and the air deflector are ensured, effectively avoiding blowing out dust during the movement of the filter screen or the air deflector, and precise small-amplitude angle adjustment can be achieved without relying on high-precision equipment, saving costs.

[0065] In this embodiment, the single-angle adjustment amount of the air deflector can be calculated through the following formula:

[0066] △θ1=[θ1_(n+1)-θ1_(n)] / dn;

[0067] wherein, △θ1 is the single-angle adjustment amount of the air deflector, n is the air duct, θ1_(n+1) is the air deflector opening angle when the air duct is n+1, θ1_(n) is the air deflector opening angle when the air duct is n, and dn is the division coefficient, and dn>1.

[0068] In this embodiment, the single-angle adjustment amount of the filter screen can be calculated by the following formula:

[0069] △θ2 = [θ2_(n+1)-θ2_(n)] / dn;

[0070] Where, △θ2 is the single-angle adjustment amount of the filter screen, n is the wind gear, θ2_(n+1) is the opening angle of the filter screen when the wind gear is n+1, θ2_(n) is the opening angle of the filter screen when the wind gear is n, and dn is the segmentation coefficient, and dn>1.

[0071] When the single-angle adjustment amount of the filter screen and the single-angle adjustment amount of the air deflector are calculated, it is also necessary to confirm the preset adjustment sequence. The preset adjustment sequence is related to the changing trend of the wind gear, which can not only reduce or avoid the blowing of dust on the dust accumulation surface, but also avoid interference between the filter screen and the air deflector during the movement process. Therefore, first judge the changing trend of the wind gear, then determine the preset sequence according to the changing trend, and then adjust the filter screen and the air deflector in turn according to the calculated data according to the preset sequence. Determining the preset sequence according to the changing trend includes: if the changing trend is that the wind gear decreases, it is determined that the preset sequence is to adjust the filter screen first and then the air deflector; if the changing trend is that the wind gear increases, it is determined that the preset sequence is to adjust the air deflector first and then the filter screen. Based on this, interference between the filter screen and the air deflector during the movement process can be avoided, and it can also ensure that dust is not blown out during the process of adjusting the angles of the filter screen and the air deflector.

[0072] Specifically, if the changing trend is that the wind gear decreases, adjusting the filter screen and the air deflector in turn according to the calculated data according to the preset sequence includes: first adjusting the opening angle of the filter screen to be smaller according to the single-angle adjustment amount of the filter screen, and then adjusting the opening angle of the air deflector to be smaller according to the single-angle adjustment amount of the air deflector, and circulating in turn until the filter screen is adjusted to the opening angle of the filter screen corresponding to the changed wind gear and the air deflector is adjusted to the opening angle of the air deflector corresponding to the changed wind gear.

[0073] Specifically, if the changing trend is that the wind gear increases, adjusting the filter screen and the air deflector in turn according to the calculated data according to the preset sequence includes: first adjusting the opening angle of the air deflector to be larger according to the single-angle adjustment amount of the air deflector, and then adjusting the opening angle of the filter screen to be larger according to the single-angle adjustment amount of the filter screen, and circulating in turn until the air deflector is adjusted to the opening angle of the air deflector corresponding to the changed wind gear and the filter screen is adjusted to the opening angle of the filter screen corresponding to the changed wind gear.

[0074] By making small movements of the filter screen and the air deflector, it is possible to effectively avoid blowing dust during the movement of the filter screen or the air deflector, and precise small-angle adjustment can be achieved without relying on high-precision equipment, saving costs.

[0075] Considering that the windshield may change again during the above-mentioned angle adjustment process, to avoid disorder or incomplete adjustment of the adjustment operation, this embodiment provides a preferred implementation method, that is, during the process of sequentially adjusting the filter screen and the air deflector in a preset order according to the calculated data, it is detected whether the windshield has changed; if it is detected that the windshield has changed, the current opening angle of the filter screen and the current opening angle of the air deflector are maintained, the single-angle adjustment amount of the filter screen and the single-angle adjustment amount of the air deflector are recalculated, and the filter screen and the air deflector are sequentially adjusted in a loop according to the calculated data in a preset order. Based on this, it can ensure that the angles of the filter screen and the air deflector are adjusted in place, ensuring the effective implementation of the solution of this embodiment.

[0076] On the basis of not increasing the hardware cost, this embodiment controls the stepping motors of the air deflector and the filter screen through software on the existing upper and lower air outlets of the air conditioner, and can complete the action adjustment and dust prevention treatment during operation without interference of moving parts. This embodiment can achieve the following technical effects: 1) The air deflector and the filter screen will also adjust their own angles during normal operation, and the dust on the filter screen will not be blown into the room during the adjustment process; 2) Without increasing the cost, it is ensured that the air deflector and the filter screen will not blow out dust at various angles and in various actions, and will not affect the normal adjustment of the filter screen and the air deflector.

[0077] Embodiment 3

[0078] Figure 6 is a detailed flowchart of dust prevention control according to an embodiment of the present invention, as Figure 6 shown, this process includes:

[0079] Step 1, the power-on calibration stage.

[0080] For open-loop control of the stepping motor, a zero point needs to be determined to control according to the number of steps.

[0081] 1) When the unit is powered on and reset, the filter screen and the air deflector need to be calibrated. Considering that the transmission ratios of the two are different during the movement process, it is necessary to avoid interference between the filter screen and the air deflector during the action. The air deflector is set outside the filter screen. Based on this, this embodiment moves to the limit switch position in the order of controlling the filter screen first and then the air deflector, that is, both are adjusted to the reset angle (for example, 40°).

[0082] In the original state, the filter screen and the air deflector may be in any state. If the previous unit operation ended with a normal shutdown, then at this time the filter screen and the air deflector should be at the reset angle. As Figure 1 shown, the included angles between the filter screen and the air deflector and the axis plane are the reset angles. When the reset angle is 40°, at this time both the filter screen and the air deflector are in a vertical state, and the dust accumulation surface is not easy to accumulate dust.

[0083] 2) The unit is powered on and reset. When the air outlet receives the unit power-on signal, since the set position of the air deflector is outside the set position of the filter screen, the opening angles θ1 of the air deflector and θ2 of the filter screen are respectively opened to the preset maximum angles θm1 (e.g., 130°) and θm2 (e.g., 132°) in the order of controlling the air deflector action first and then the filter screen action;

[0084] 3) When θ1 = θm1 and θ2 = θm2, it means that the air deflector and the filter screen have been adjusted to the target positions. These angles are the angles verified by experiments not to blow out dust. The above target positions of each unit are affected by factors such as the size of the filter holes, the filter material, and the axial distance between the filter screen and the air deflector movement axis. Therefore, the above angle sizes need to be obtained through experimental data testing. Then, send a signal to the indoor unit to enable the air supply fan. The indoor unit determines whether to turn on the fan according to the current unit state. If the current unit state meets the conditions for turning on the fan, the fan is turned on.

[0085] Step 2, operation control stage.

[0086] Judge whether the unit enables the anti-direct-blow function. If the anti-direct-blow function is not enabled, the filter screen and the air deflector are maintained at the current angles. If the anti-direct-blow function is enabled, the air deflector and filter screen angles are adjusted according to the current indoor fan speed to determine the wind speed range, ensuring that the wind does not blow directly on people.

[0087] When the anti-direct-blow function is enabled, when the fan speed increases (the wind speed range increases), the wind speed becomes faster at this time, and the angle of the air deflector should be increased so that the wind can blow out parallel, making the cold air blow farther and not immediately blow down to the user; when the fan speed decreases (the wind speed range decreases), the angle of the air deflector should be decreased so that the low-speed cold air can blow farther and prevent it from blowing down to the user prematurely.

[0088] The wind speed ranges are divided according to the fan speed and are divided into multiple ranges. In this embodiment, taking 6 ranges as an example: from low to high speed, they are divided into wind speed ranges 1 - 6. Each range has a corresponding wind speed interval, as shown in Table 1 below. Table 1 shows the speed intervals, filter screen opening angles, and air deflector opening angles corresponding to different wind speed ranges.

[0089] Table 1

[0090] Windshield 1(speed1) 2(speed2) 3(speed3) 4(speed4) 5(speed5) 6(speed6) Speed range (unit: n / min) [SPEED1,SPEED2)[300,400) [SPEED2,SPEED3)[400,500) [SPEED3,SPEED4)[600,700) [SPEED4,SPEED5)[800,900) [SPEED5,SPEED6)[900,1000) [SPEED6,SPEED7][1000,1100) Filter opening angle (unit: degree) θ2_1: 89 θ2_2: 94 θ2_3: 98 θ2_4: 103 θ2_5: 108 θ2_6: 112 Air deflector opening angle (unit: degree) θ1_1: 85 θ1_2: 90 θ1_3: 95 θ1_4: 100 θ1_5: 105 θ1_6: 110

[0091] Among them,

[0092] Reset angle θ < θ2_1 < θ2_2 < θ2_3 < θ2_4 < θ2_5 < θ2_6 < maximum θm2;

[0093] Reset angle θ < θ1_1 < θ1_2 < θ1_3 < θ1_4 < θ1_5 < θ1_6 < maximum θm1.

[0094] The angular velocity w2 of the filter screen is greater than the angular velocity w1 of the air deflector (the filter screen is lighter than the air deflector, and it is easier for the motor to drive the filter screen to rotate. If the filter screen is heavier, the angular velocity will be smaller). The opening angle of the filter screen is always greater than that of the air deflector to reduce the blowing out of dust on the dust accumulation surface. The smaller the opening angle, the greater the angle difference between the two.

[0095] The specific values of the above angles are related to the axial distance and weight of the two.

[0096] The rotational speed speed corresponding to the wind gear satisfies:

[0097] SPEED1 < speed1 < SPEED2,

[0098] SPEED2 < speed2 < SPEED3,

[0099] SPEED3 < speed3 < SPEED4,

[0100] SPEED4 < speed4 < SPEED5,

[0101] SPEED5 < speed5 < SPEED6,

[0102] SPEED6 < speed6 < SPEED7.

[0103] The angles under different wind gears have been adjusted through experiments and are the optimal angles for current non-dust blowing and anti-direct blowing.

[0104] When the wind gear changes, the following control method is used for adjustment:

[0105] The angles of the filter screen and the air deflector are split and processed as follows: The corresponding angle intervals of each gear are calculated according to the formula

[0106] △θ1 = [θ1_(n + 1) - θ1_(n)] / dn

[0107] △θ2 = [θ2_(n + 1) - θ2_(n)] / dn;

[0108] In the formula:

[0109] △θ1 is the single-angle adjustment amount of the air deflector;

[0110] θ1_(n) corresponds to the air deflector opening angles θ1_1~θ1_6 in Table 1;

[0111] △θ2 is the single-angle adjustment amount of the filter screen;

[0112] θ2_(n) corresponds to the filter opening angles θ2_1 to θ2_6 in Table 1;

[0113] n is the wind speed, corresponding to subscripts 1 to 6;

[0114] dn is the division coefficient, dn>1, the larger the wind gear is, the smaller the single angle adjustment amount is, so the larger n is, the larger dn is. Preferably, dn can be set to 8.

[0115] In addition, θ1_6 to the maximum θm1 and θ2_6 to the maximum θm2 are divided according to the following formula:

[0116] △θ1=[maximum θm1-θ1_6] / dn

[0117] △θ2=[maximumθm2-θ2_6] / dn.

[0118] It should be noted that the split coefficient is an adjustment coefficient to specifically determine how to split the angle, so that a large wind deflector angle difference is divided into many small intervals for adjustment, so that the wind deflector and the filter can be adjusted synchronously at a smaller angle, so that this adjustment task can be completed without the use of high-precision control equipment and complex control methods. The greater the wind speed, the smaller the distance (gap) between the wind deflector and the filter needs to be to avoid blowing dust. During the movement, the gap between the two needs to be kept within a range that does not fluctuate too much, so the split needs to be finer.

[0119] A. Windshield lowering control:

[0120] The filter stops moving when it moves from θ2_(n+1) to θ2_(n+1)-△θ2, and when the air guide plate moves from θ1_(n+1) to θ1_(n+1)-△θ1, the filter continues to adjust △θ2, and repeats the above actions until the target position is reached; (adjust the filter first and then the air guide plate).

[0121] There is a case where, when the direct blow protection function is turned on for the first time, the windshield lowering control is also performed because the adjustment is started from the maximum angle.

[0122] B. Windshield lifting control:

[0123] When the air guide plate moves from θ1_(n) to θ1_(n)+△θ1, the filter starts to move from θ2_(n) to θ2_(n)+△θ2 and then stops. When the air guide plate continues to adjust to θ1_(n)+2×△θ1, the filter starts to move from θ2_(n)+△θ2 to θ2_(n)+2×△θ2 and then stops. The above actions are repeated until the target position is reached.

[0124] In one case, after turning on the anti-direct-blow function and then turning it off, since the filter screen and the air deflector need to be adjusted to the maximum angle, the wind speed gear increase control needs to be executed.

[0125] If a wind speed gear change occurs during the above-mentioned adjustment processes A (wind speed gear decrease control) and B (wind speed gear increase control), the air deflector stops at the next segmentation position after reaching it. That is, during the angle adjustment process, if a wind speed gear change occurs before the adjustment is completed, the current round of adjustment operation is directly ended, Δθ1 and Δθ2 are recalculated, and a new round of adjustment operation is executed. Then, it is determined again whether the wind speed decreases or increases, and the step count is adjusted until the target position is finally reached.

[0126] Taking the wind speed gear increase as an example, when the wind speed gear changes from 2 to 3, if d×m = 8 at this time, then Δθ1 = 0.5°, Δθ2 = 0.625°. Then, it is controlled that the air deflector starts to move from 90° to 90.5°. After reaching the target, the filter screen moves from 94° to 94.625°. Then, after the filter screen reaches the position, the air deflector continues to move forward, and this movement is repeated until the target position is reached. Thus, interference between the air deflector and the filter screen can be avoided.

[0127] III. Shutdown stage.

[0128] During the above control process, after receiving the shutdown instruction, wait for the current control action to be completed, wait for the fan to stop, and then execute a power-on reset action.

[0129] Based on the software control without increasing the hardware cost, in this embodiment, on the existing upper and lower air outlets of the air conditioner, the stepping motors for controlling the air deflector and the filter screen are controlled, so that the movement components can complete the action adjustment during operation and the anti-dust treatment without interference. This embodiment can achieve the following technical effects: 1) The air deflector and the filter screen will also adjust their own angles during normal operation, and the dust on the filter screen will not be blown into the room during the adjustment process; 2) Without increasing the cost, it is ensured that the air deflector and the filter screen will not blow out dust at various angles and in various actions, and it will not affect the normal adjustment of the filter screen and the air deflector.

[0130] Embodiment 4

[0131] Corresponding to Figure 5 the anti-dust control method introduced above, this embodiment provides an anti-dust control device, such as Figure 7 the structural block diagram of the anti-dust control device shown. The above device is applied to the air outlet assembly, and the air outlet assembly includes: a filter screen arranged on the air outlet frame through a first transmission shaft, and an air deflector arranged on the air outlet frame through a second transmission shaft; the device includes:

[0132] The acquisition module 10 is used to obtain the wind speed corresponding to the fan speed after the unit is powered on and reset; wherein the correspondence between different wind speeds and the filter opening angle and the air guide plate opening angle is preset, and the filter opening angle corresponding to each wind speed is always greater than the air guide plate opening angle;

[0133] The control module 20 is connected to the acquisition module 10 and is used to control the filter to rotate to the filter opening angle corresponding to the wind gear, and control the wind deflector to rotate to the wind deflector opening angle corresponding to the wind gear;

[0134] The adjustment module 30 is connected to the control module 20, and is used to calculate the single angle adjustment amount of the filter and the single angle adjustment amount of the air guide plate when a change in the wind gear is detected, and cyclically adjust the filter and the air guide plate in sequence according to the calculated data in a preset order.

[0135] This embodiment takes into account that the air guide plate and the filter will adjust their own angles when air is discharged from the air vent. During this process, the opening angle and angle adjustment speed of the air guide plate and the filter are controlled. Without increasing the hardware cost and without affecting the normal operation of the air guide plate and the filter of the air vent, it is effectively prevented that the dust adsorbed on the filter is blown into the room, ensuring that the air guide plate and the filter will not blow out dust at all opening angles.
