Description

Technical Field

[0001] The present invention relates to the field of air conditioners, and particularly to a dust removal device, an air conditioner, and an air conditioner dust removal control method. Background Art

[0002] With the improvement of living standards, people have put forward higher requirements for the quality of indoor air; currently, the air is mainly filtered through a filter screen. After the filter screen is used for a period of time, the outer surface will be covered with dust, resulting in blockage. If it is not cleaned in time, the ventilation volume will be significantly reduced, and the air quality will also deteriorate. Traditional air conditioners require manual cleaning of the filter screen. First, the filter screen is disassembled, then the dust on the filter screen is removed, and finally the filter screen is reinstalled, which is very inconvenient to operate.

[0003] In order to be able to automatically clean the filter screen, in the existing technology, a filter screen similar to a conveyor belt that can rotate in a cycle is often used. When the filter screen needs to be cleaned, the filter screen is rotated, and the filter screen is cleaned by a cleaning device. Since this filter screen rotates in a cycle, the height of the air conditioner is relatively high, and the lowest point of the air conditioner is relatively close to the indoor ground, which is not convenient for indoor users to move; since it is arranged at the air inlet of the air conditioner in the form of a conveyor belt, it is equivalent to double filtration, increasing the air inlet resistance of the air conditioner. To ensure the normal air inlet of the air conditioner, the energy consumption of the air conditioner needs to be increased, which is not conducive to environmental energy conservation.

[0004] In view of the above technical problems, there is currently no good solution. Summary of the Invention

[0063] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way constitutes a limitation to the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0064] It should be noted that the terms used here are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form.

[0065] In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof; the term "including", "comprising", or any other variant thereof is intended to cover non-exclusive inclusion, such that a commodity or system including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the presence of additional identical elements in the commodity or system including said element.

[0066] It should be understood that the term "and / or" used herein is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0067] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience in description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0068] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings, and are merely for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus should not be construed as limiting the protection scope of the present invention; the orientation terms "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0069] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures.

Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0070] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components, rather than having a sequential order; without otherwise stating, the above terms have no special meaning, and thus cannot be construed as a limitation on the protection scope of the present invention.

[0071] The present invention relates to the field of air conditioners, and particularly relates to a dust removal device, an air conditioner, and an air conditioner dust removal control method.

[0072] With the improvement of living standards, people have put forward higher requirements for the quality of indoor air; currently, the air is mainly filtered by a filter screen. After the filter screen is used for a period of time, the outer surface will be covered with dust, resulting in blockage. If it is not cleaned in time, the ventilation volume will be significantly reduced and the air quality will also deteriorate. Traditional air conditioners require manual cleaning of the filter screen. First, the filter screen is removed, then the dust on the filter screen is removed, and finally the filter screen is reinstalled, which is very inconvenient to operate.

[0073] In order to be able to automatically clean the filter screen, in the existing technology, a filter screen similar to a conveyor belt that can rotate in a cycle is often used. When the filter screen needs to be cleaned, the filter screen is rotated, and the filter screen is cleaned by a cleaning device. Since this filter screen rotates in a cycle, the height of the air conditioner is relatively high, and the lowest point of the air conditioner is relatively close to the indoor ground, which is not convenient for indoor users to move; since it is arranged at the air inlet of the air conditioner in the form of a conveyor belt, it is equivalent to double filtration, increasing the air inlet resistance of the air conditioner. To ensure the normal air inlet of the air conditioner, the energy consumption of the air conditioner needs to be increased, which is not conducive to environmental energy conservation.

[0074] To solve the technical problem that the height of an air conditioner equipped with a dust removal device with an automatic cleaning function is relatively high, a dust removal device, an air conditioner, and an air conditioner dust removal control method are proposed herein.

[0075] The present invention provides a dust removal device, as Figure 1-14 shown, which is arranged inside an air conditioner indoor unit and is used for cleaning the filter net 1; the air conditioner indoor unit includes a cross-flow fan blade and an air inlet; the filter net 1 is used for filtering the air entering the air conditioner indoor unit through the air inlet of the air conditioner indoor unit. The dust removal device is provided with a dust removal area 2 and a filtering area 3. The filtering area 3 is located at the air inlet of the air conditioner indoor unit, and the dust removal area 2 is located on one side in the axial direction of the cross-flow fan blade. The filter net 1 is a flexible plate;

[0076] The filter net 1 can move between the filtering area 3 and the dust removal area 2. When the filter net 1 moves to the filtering area 3, it is in a horizontal state, and when the filter net 1 moves in the dust removal area 2, it is in a vertical state;

[0077] The dust removal area 2 is provided with a dust removal component, and the dust removal component can clean the filter net 1 in the dust removal area 2.

[0078] The "horizontal" and "vertical" in this application refer to the spatial relationship during actual use and do not limit the specific structure.

[0079] The filter net 1 is arranged inside the air inlet of the air conditioner and is located above the evaporator. The flexible plate-shaped filter net 1 is convenient for the filter net 1 to be converted between the horizontal state and the vertical state.

[0080] The dust removal area 2 is arranged on one side in the axial direction of the cross-flow fan blade. The flexible plate-shaped filter net 1 can move between the dust removal area 2 and the filtering area 3, and is in a horizontal state in the filtering area 3 and in a vertical state in the dust removal area 2. Compared with the double-layer annular filter net 1 that can rotate in a cycle, the filter net 1 arranged at the air inlet of the air conditioner in this application is single-layer, and the height of the air conditioner indoor unit is lower, which is convenient for indoor installation and occupies less indoor height space; the dust removal area 2 is arranged on one side in the axial direction of the cross-flow fan blade, and the filter net 1 is in a vertical state in the dust removal area 2, which also makes the size of the air conditioner indoor unit in the length direction of the cross-flow fan blade smaller, further reducing the space occupied by the air conditioner indoor unit; when dust removal is carried out in the vertical state of the filter net 1, it is beneficial for the removed dust to move downward under the action of gravity, reducing the possibility that the removed dust adheres to the filter net 1 again, which is beneficial to improving the dust removal effect. The plate-shaped filter net 1 is convenient for the filter net 1 to be converted between the horizontal state and the vertical state, which is beneficial to reducing the space required for the filter net 1 to be converted between the horizontal state and the vertical state.

[0081] In the dust removal area 2, the filter net 1 is cleaned by the dust removal component, and there is no need to disassemble the filter net 1 for cleaning, which reduces the maintenance difficulty of the air conditioner and improves the user experience. The dust removal component includes a fixed end and a cleaning end. The cleaning end is used for cleaning the filter net 1, and the fixed end is used for fixing the cleaning end.

[0082] Preferably, as Figure 1-6 shown, the dust removal device is provided with a temporary storage area 4, and the temporary storage area 4 is connected to the dust removal area 2; the filter net 1 can move from the dust removal area 2 to the temporary storage area 4.

[0083] When the size of the filter net 1 is large (along the moving direction of the filter net 1, the filter net 1 is long), the filter net 1 cannot enter the dust removal area 2 all at once, and only a part of it can enter the dust removal area 2 at a time. After dust removal of the part of the filter net 1 that enters the dust removal area 2, the filter net 1 moves to make this part of the dust-removed filter net 1 move to the temporary storage area 4. At the same time, the part of the filter net 1 that has not been dust-removed enters the dust removal area 2 for filtration; in this way, all of the filter net 1 is dust-removed. Since the dust removal area 2 needs to set aside space not only for the filter net 1 but also for the dust removal components, while the temporary storage area 4 only needs to set aside space for the filter net 1, in this way, it is possible to avoid making the dust removal area 2 too large, which is beneficial to reducing the size of the indoor unit of the air conditioner.

[0084] Preferably, as Figure 1 and Figure 8 shown, the temporary storage area 4 is located between the dust removal area 2 and the cross-flow fan blade. The temporary storage area 4 includes a temporary storage track 400. The temporary storage track 400 includes a guide rail A411 and a guide rail B412. The guide rail A411 and the guide rail B412 are arranged on both sides of the moving direction of the filter net 1;

[0085] The filter net 1 includes a filtering part and a net frame for keeping the filter net 1 in an unfolded state. The net frame can move along the guide rail A411 and the guide rail B412.

[0086] By providing the temporary storage track 400, the filter net 1 can move and be temporarily stored in the temporary storage track 400 according to the designed regulations, which is beneficial to keeping the filter net 1 flat and avoiding the filter net 1 being freely stacked, resulting in damage to the filter net 1; at the same time, the filter net 1 moving along the temporary storage track 400 can improve the smoothness of the movement of the filter net 1.

[0087] By providing the net frame, the stability of the filter net 1 is improved, so that both sides of the filter net 1 can stably move along the guide rail A411 and the guide rail B412. The net frame includes a frame for fixing the four sides of the filter net 1 and a cross beam 103 connecting the frames of the opposite sides.

[0088] Preferably, as Figure 1-3 shown, the temporary storage track 400 includes a first track 401 and a second track 402. The first track 401 extends from the dust removal area 2 towards the cross-flow fan blade, and the second track 402 extends from bottom to top; the lower end of the second track 402 is connected to one end of the first track 401 close to the cross-flow fan blade.

[0089] By setting the first track 401 and the second track 402, with the first track 401 extending from the dust removal area 2 towards the air duct and the second track 402 extending from bottom to top; thereby reducing the space occupied by the temporary storage track 400, and further reducing the indoor space occupied by the air conditioner indoor unit, which is beneficial to the user experience.

[0090] Preferably, the temporary storage track 400 further includes a third track and a fourth track (not shown in the figure). The third track is connected to the upper end of the second track 402, and the third track extends from one side of the cross-flow fan towards the dust removal area 2; the fourth track extends from top to bottom, and the upper end of the fourth track is connected to one end of the third track close to the dust removal area 2; a first gap is formed between the fourth track and the second track, and a second gap is formed between the fourth track and the dust removal area 2.

[0091] By setting the third track and the fourth track and arranging them as described above, it is beneficial to extend the length of the temporary storage track 400, which can be used to temporarily store a longer filter net 1. Since the third track and the fourth track are arranged in the area between the dust removal area 2 and the cross-flow fan, they do not occupy additional space; since a first gap is formed between the fourth track and the second track 402 and a second gap is provided between the fourth track and the dust removal area 2, the filter net 1 will not come into contact and friction with other structures, and the filter net 1 itself will not have contact and friction either. In this way, the movement stability of the filter net 1 is ensured, and the filter net 1 in the dust removal area 2 is prevented from affecting the already dust-removed filter net 1 during dust removal, ensuring the cleanliness of the filter net 1.

[0092] Preferably, as Figure 2 shown, a dust removal track 5 is vertically arranged in the dust removal area 2, and a filtering track 6 is horizontally arranged in the filtering area 3. The lower end of the dust removal track 5 is connected to one end of the temporary storage track 400 close to the dust removal area 2, and the upper end of the dust removal track 5 is connected to one end of the filtering track 6 close to the dust removal area 2.

[0093] By setting the filtering track 6 and the dust removal track 5, the filter net 1 can move smoothly between the dust removal area 2 and the filtering area 3, improving the movement stability of the filter net 1.

[0094] Preferably, as Figure 1-5As shown, a first gear set 701 is provided at the junction of the filtering track 6 and the dust removal track 5, a second gear set 702 is provided at the junction of the dust removal track 5 and the first track 401, and a third gear set 703 is provided at the junction of the first track 401 and the second track 402; the tooth modules of the teeth of the first gear set 701, the second gear set 702, and the third gear set 703 are the same; a tooth groove is provided on the filtering frame, and the tooth groove is matched with the teeth of the first gear set 701, and the first gear set 701, the second gear set 702, and the third gear set 703 can rotate synchronously.

[0095] By providing gear sets at the junctions of different tracks and a tooth groove on the filtering frame, and the gear sets are matched with the tooth groove, since there is no relative sliding, the movement of the filter net 1 is more precise; since the gear sets are provided at the junctions of different tracks, that is, at the turning points, it is beneficial to change the moving direction of the filter net 1 and avoid the filter net 1 being unable to turn and move at the turning points.

[0096] Preferably, as Figure 2 shown, the dust removal device is further provided with a first motor 801 and a second motor 802, the first motor 801 drives the first gear set 701, the second motor 802 drives the second gear set 702, and the second motor 802 drives the third gear set 703 through chain drive.

[0097] Driving the first gear set 701 and the second gear set 702 to rotate by the first motor 801 and the second motor 802 is beneficial to controlling the movement of the filter net 1. The second motor 802 drives the third gear set 703 through a chain, which can reduce the number of motors installed and lower the cost. Driving two motors simultaneously by the second motor 802 is beneficial to the synchronous rotation of the second gear set 702 and the third gear set 703 and beneficial to the consistent rotation speed of different parts of the filter net 1. The motors can be set as servo motors, and thus the moving distance of the filter net 1 can be controlled more precisely.

[0098] The sizes of the first motor 801 and the second motor 802 may affect the movement of the filter net 1. Gears can be provided at the output ends of the first motor 801 and the second motor 802, and the first gear set 701 and the second gear set 702 are driven through the gears to prevent the outer shells of the first motor 801 and the second motor 802 from coming into contact with the filter net 1.

[0099] Preferably, as Figure 1-5 shown, the dust removal component includes a first cleaning brush 901, the first cleaning brush 901 can move up and down, and the first cleaning brush 901 can contact or separate from the filter.

[0100] The first cleaning brush 901 moves up and down to clean the filter net 1 multiple times, improving the cleanliness of the filter net 1; the first cleaning brush 901 contacts or separates from the filter net 1, enabling the first cleaning brush 901 to clean the filter net 1 in one direction. Considering the actual situation, when the first cleaning brush 901 moves downward, as Figure 8 and Figure 12 shown, the first cleaning brush 901 contacts the filter net 1 to clean the filter net 1, and after the dust is removed from the filter net 1, it can fall downward faster under the action of gravity; when the first cleaning brush 901 moves upward, as Figure 9 and Figure 11 shown, the first cleaning brush 901 separates from the filter net 1 and does not clean the filter net 1, preventing the dust after cleaning from drifting upward under the action of the first cleaning brush 901. On the one hand, the upward drifting of the dust will cause the dust to not be collected in time, which is harmful to the indoor unit of the air conditioner. On the other hand, the dust will eventually drift downward under the action of gravity, and the downward drifting of the dust will contaminate the already cleaned filter net 1, reducing the cleaning effect.

[0101] Preferably, as Figure 13 shown, the first cleaning brush 901 is a rolling brush, and when the rolling brush contacts and rolls with the filter net 1, it has a force that makes the dust on the filter net 1 move downward.

[0102] The first cleaning brush 901 can be a rolling brush. When the first cleaning brush 901 moves downward, the rolling brush rotates itself, and the part of the brush that contacts the filter net 1 moves downward during rotation. That is, the rotation of the rolling brush has a force that moves the dust on the filter net 1 downward. In this way, the relative movement distance between the first cleaning brush 901 and the filter net 1 is increased (relative movement distance, for example: if the rolling brush does not move downward but only rotates, when the rolling brush rotates one week, the relative movement distance between the rolling brush, that is, the first cleaning brush 901 and the filter net 1 is the circumference of one week of the rolling brush rotation), improving the cleaning effect.

[0103] Preferably, as Figure 14 shown, the first cleaning brush 901 is fixedly arranged in the dust removal area 2 and can cover the dust removal area 2.

[0104] By fixedly arranging the first cleaning brush 901, the structure is simplified, and the production cost and maintenance difficulty are reduced. Since the first cleaning brush 901 covers the entire area of the dust removal area 2, the cleaning area of the first cleaning brush 901 for the filter net 1 is increased. When the filter net 1 moves, the filter net 1 moves relative to the first cleaning brush 901, and the dust on the filter net 1 is cleaned off. Since the coverage area of the first cleaning brush 901 is relatively large, the filter net 1 can be continuously cleaned, improving the cleaning effect.

[0105] Preferably, asFigure 1 and Figure 3 - Figure 5 As shown, a second cleaning brush 902 is provided at the connection between the temporary storage area 4 and the dust removal area 2, and a storage box 903 is provided below the connection between the dust removal area 2 and the temporary storage area 4.

[0106] When the filter screen 1 moves from the dust removal area 2 to the temporary storage area 4, the second cleaning brush 902 provided at the connection between the temporary storage area 4 and the dust removal area 2 re-cleans the filter screen 1, preventing dust from being carried into the temporary storage area 4, improving the cleanliness of the filter screen 1, ensuring the cleanliness of the temporary storage area 4, and preventing dust from entering the temporary storage area 4. If dust enters the temporary storage area 4, it will accumulate in the temporary storage area 4 over time, resulting in the filter screen 1 being contaminated in the temporary storage area 4 after cleaning.

[0107] A storage box 903 is provided below the connection between the dust removal area 2 and the temporary storage area 4. This storage box 903 can collect the dust cleaned by the first cleaning brush 901 and the second cleaning brush 902, eliminating the need to set up multiple storage boxes 903; the storage box 903 can be set as a drawer-type box for easy cleaning of the storage box 903.

[0108] Preferably, as Figure 6 shown, the dust removal area 2 is provided with a cleaning guide rail, and the dust removal component further includes a sliding block 900 that can slide up and down along the cleaning guide rail. The first cleaning brush 901 is provided on the sliding block 900;

[0109] An electromagnetic component and an elastic component are provided between the sliding block 900 and the first cleaning brush 901, and the electromagnetic component and the elastic component can cooperate to control the first cleaning brush 901.

[0110] By providing the cleaning track and the sliding block 900, the first cleaning brush 901 can be driven to move up and down more conveniently and stably;

[0111] The first cleaning brush 901 is intermittently in contact with the filter net 1 through the electromagnetic component and the elastic component. The movement of the first cleaning brush 901 can be divided into two processes; the first process is that the first cleaning brush 901 moves downward. At this time, the electromagnetic component is energized, and the first cleaning brush 901 contacts the filter net 1 under the action of the electromagnetic force and deforms the elastic component. At this time, the first cleaning brush 901 cleans the filter net 1, and the dust on the filter net 1 falls downward under the action of gravity and the downward movement of the first cleaning brush 901. Since the first cleaning brush 901 moves downward, the dust falling on the filter net 1 will not float upward, thus avoiding the re - pollution of the already cleaned filter net 1 caused by the dust flying everywhere; the second process is that the first cleaning brush 901 moves upward. At this time, the electromagnetic component is powered off, and the first cleaning brush 901 is no longer affected by the electromagnetic force. The first cleaning brush 901 moves away from the filter net 1 (close to the sliding block 900) and separates from the filter net 1 under the action of the elastic component. Since the first cleaning brush 901 separates from the filter net 1, the first cleaning brush 901 will no longer clean the filter net 1, and it also avoids the dust on the filter net 1 from floating upward; if the filter net 1 needs to be cleaned continuously, the first process and the second process can be repeated; the number of repetitions can be preset in advance or can be automatically cycled according to the cleanliness of the filter net 1. By controlling the movement state of the first cleaning brush 901 through the cooperation of the electromagnetic component and the elastic component, the simplicity and stability of the movement of the first cleaning brush 901 are improved.

[0112] Of course, it can also be that when the electromagnetic component is energized, the first cleaning brush 901 separates from the filter net 1, and when the electromagnetic component is powered off, the first cleaning brush 901 contacts the filter net 1 under the action of the elastic component.

[0113] The elastic component can be a spring, specifically, a tension spring or a compression spring.

[0114] When controlling the cleaning times of the first cleaning brush 901 according to the cleanliness of the filter net 1, it can be done by means of light. For example, on both sides of the mesh surface of the filter net 1 in the dust removal area 2, a light source is set on one side, and a device for checking brightness or light intensity is set on the other side. When the detected brightness is greater than the preset value, or the light intensity is greater than the preset value, it can be judged that the cleaning of the filter net 1 meets the requirements; if the preset value is not reached, the first process and the second process can be continued to be repeated. Compared with the method of detecting dust by blowing air, this detection method can avoid the dust from floating everywhere under the drive of the gas, causing pollution to the indoor unit of the air conditioner or floating into the room and polluting the indoor environment.

[0115] Preferably, as Figure 1 shown, the dust removal device further includes a third motor 803 and a screw rod 813. The screw rod is arranged vertically and is connected to the sliding block 900. When the third motor 803 works, it can drive the screw rod 813 to rotate, and when the screw rod 813 rotates, it can drive the sliding block 900 to move along the dust removal guide rail.

[0116] The screw 813 is driven by the third motor 803. In the way that the rotation of the screw 813 drives the slider 900 to move up and down, finally drives the first cleaning brush 901 to move. Only by the forward and reverse rotation of the third motor 803 can the first cleaning brush 901 be driven to move up or down; thus, the first cleaning brush 901 can move up and down stably, making the first cleaning brush 901 better clean the filter net 1.

[0117] The present invention also provides an air conditioner, such as Figure 1 shown, which includes an indoor unit. The dust removal device as described above is arranged in the indoor unit, and the filtering area 3 is arranged at the air inlet of the indoor unit.

[0118] By arranging the above dust removal device, the air entering the air conditioner can be filtered and automatically cleaned; since the filter net 1 is a flexible plate, compared with the "conveyor belt" - type filter net 1, the height of the indoor unit is lower. In this way, the distance from the bottom of the room to the indoor ground can be higher, reducing the occupation of indoor space and improving the user experience. When the filter net 1 is in the dust removal area 2, it is in a vertical state, facilitating the dust cleaned from the filter net 1 to fall downward into the storage box 903 under the action of gravity, avoiding the dust from entering the indoor space driven by the air blades of the indoor unit, which is beneficial to ensuring the cleanliness of the indoor air.

[0119] The present invention also provides an air conditioner dust removal control method for the above - mentioned air conditioner.

[0120] Preferably, the air conditioner dust removal control method is as follows:

[0121] Step 1, the filter net 1 moves from the filtering area 3 to the dust removal area 2 by a preset length;

[0122] Step 2, the first cleaning brush 901 moves towards the filter net 1 and presses the filter net 1;

[0123] Step 3, the first cleaning brush 901 moves downward to the separation position;

[0124] Step 4, at the separation position, the first cleaning brush 901 moves away from the filter net 1 and separates from the filter net 1;

[0125] Step 5, the first cleaning brush 901 moves upward to the contact position.

[0126] Such as Figure 15 shown, in Step 1, the filter net 1 moves from the filtering area 3 to the dust removal area 2 by a preset length;

[0127] In the dust removal area 2, the filter screen 1 is cleaned by the first cleaning brush 901. The preset length is determined according to the distance of the up and down movement of the first cleaning brush 901. The actual movement distance of the filter screen 1 can be determined by the number of rotation turns of the first motor 801. The first motor 801 can be set as a servo motor, so as to more accurately control the movement distance of the filter screen 1.

[0128] Step two, the first cleaning brush 901 moves towards the filter screen 1 and presses the filter screen 1;

[0129] The electromagnetic component is energized to generate an attractive force or a repulsive force on the first cleaning brush 901, so that the first cleaning brush 901 contacts the filter screen 1; For the specific process, control the electromagnetic component to be energized.

[0130] Step three, the first cleaning brush 901 moves downwards to the separation position;

[0131] The first cleaning brush 901 moves downwards to clean the filter screen 1; For the specific process, control the third motor 803 to be energized and rotate forward. The forward rotation of the third motor 803 drives the screw rod 813 to rotate, and the rotation of the screw rod 813 drives the sliding block 900 to move downwards. The contact position is the spatial position when the first cleaning brush 901 first contacts the filter screen 1, and it does not change due to the movement of the filter screen 1. Generally, the contact position is the highest position where the first cleaning brush 901 can move upwards.

[0132] Step four, at the separation position, the first cleaning brush 901 moves away from the filter screen 1 and separates from the filter screen 1;

[0133] The separation of the first cleaning brush 901 from the filter screen 1 facilitates the upward movement of the first cleaning brush 901; For the specific process, the electromagnetic component is powered off, and the first cleaning brush 901 separates from the filter screen 1 under the action of the elastic member.

[0134] Step five, the first cleaning brush 901 moves upwards to the contact position;

[0135] The upward movement of the first cleaning brush 901 prepares for the next round of cleaning; For the specific process, the second motor 802 is energized and rotates reversely, and the rotation of the screw rod 813 drives the sliding block 900 to move upwards to the contact position.

[0136] Preferably, the air conditioner dust removal control method further includes:

[0137] Step six, detect the cleanliness of the filter screen 1;

[0138] Step seven, compare the detected cleanliness of the filter screen 1 with the preset cleanliness range. When the cleanliness of the filter screen 1 is outside the preset cleanliness range, sequentially execute steps two to seven. When the cleanliness of the filter screen 1 is within the preset cleanliness range, execute step eight;

[0139] Step Eight: The filter screen 1 moves from the dust removal area 2 to the temporary storage area 4. Meanwhile, it is detected whether the filter screen 1 fills the temporary storage area 4 and whether the filter screen 1 moves a preset length. When the filter screen 1 moves the preset length, Steps One to Eight are executed in sequence. When the filter screen 1 fills the temporary storage area 4, Step Nine is executed;

[0140] Step Nine: Steps Two to Six are executed in sequence, and then Step Ten is executed;

[0141] Step Ten: The cleanliness of the detected filter screen 1 is compared with the preset cleanliness range. When the cleanliness of the filter screen 1 is outside the preset cleanliness range, Steps Two to Six and Step Ten are executed. When the cleanliness of the filter screen 1 is within the preset cleanliness range, Step Eleven is executed;

[0142] Step Eleven: The filter screen 1 moves from the dust removal area 2 to the filtration area 3.

[0143] Step Six: The cleanliness of the filter screen 1 is detected;

[0144] By detecting the cleanliness of the filter screen 1, it is judged whether the filter screen 1 meets the requirements;

[0145] Step Seven: The detected cleanliness of the filter screen 1 is compared with the preset cleanliness range. When the cleanliness of the filter screen 1 is outside the preset cleanliness range, Steps Two to Seven are executed in sequence. When the cleanliness of the filter screen 1 is within the preset cleanliness range, Step Eight is executed;

[0146] When the cleanliness of the filter screen 1 is outside the preset cleanliness range, it indicates that the cleanliness of the filter screen 1 is unqualified and needs to be cleaned continuously. At this time, Steps Two to Seven are executed. When the cleanliness of the filter screen 1 is within the preset cleanliness range, it indicates that the cleanliness of the filter screen 1 is qualified, and the filter screen 1 in the dust removal area 2 does not need to be cleaned continuously;

[0147] Step Eight: The filter screen 1 moves from the dust removal area 2 to the temporary storage area 4. Meanwhile, it is detected whether the filter screen 1 fills the temporary storage area 4. When the filter screen 1 does not fill the temporary storage area 4, Steps One to Eight are executed in sequence. When the filter screen 1 fills the temporary storage area 4, Step Nine is executed;

[0148] When the filter screen 1 does not fill the temporary storage area 4, it indicates that there is still filter screen 1 that has not entered the dust removal area 2. Then, the length of the filter screen 1 entering the dust removal area 2 should move according to the preset length, and Steps One to Eight are executed. When the filter screen 1 fills the temporary storage area 4, at this time, there is no space left in the temporary storage area 4, indicating that the last part of the filter screen 1 has completely entered the dust removal area 2, and the next step is executed;

[0149] A first travel switch 101 can be set at the end of the temporary storage area 4. When the filter screen 1 triggers the first travel switch 101, the filter screen 1 stops moving.

[0150] Step Nine, sequentially execute Step Two to Step Six, and then execute Step Ten;

[0151] Since the last section of the filter screen 1 moves from the filtering area 3 to the dust removal area 2 and the cleanliness does not need to be detected, Steps Two to Six can be directly executed to clean the last section of the filter screen 1 in the dust removal area 2, and then the next step is executed;

[0152] Step Ten, compare the detected cleanliness of the filter screen 1 with the preset cleanliness range. When the cleanliness of the filter screen 1 is outside the preset cleanliness range, sequentially execute Step Two to Step Six and Step Ten. When the cleanliness of the filter screen 1 is within the preset cleanliness range, execute Step Eleven;

[0153] When the cleanliness of the filter screen 1 is outside the preset cleanliness range, the filter screen 1 needs to be continuously cleaned, and Steps Two to Six and Step Ten are executed; when the cleanliness of the filter screen 1 is within the preset cleanliness range, the cleanliness of the filter screen 1 is qualified, and the next step is executed;

[0154] Step Eleven, the filter screen 1 moves from the dust removal area 2 to the filtering area 3.

[0155] After the filter screen 1 is cleaned, it moves from the dust removal area 2 to the filtering area 3 to filter the air.

[0156] A second travel switch 102 can be set at the end of the filtering area 3. When the filter screen 1 triggers the second travel switch 102, the filter screen 1 stops moving.

[0157] Preferably, Step Two further includes: the first cleaning brush 901 rotates self - clockwise.

[0158] The first cleaning brush 901 rotates self - clockwise to improve the cleaning efficiency of the filter screen 1.

[0159] Preferably, Step Eight further includes: when the filter screen 1 moves from the dust removal area 2 to the temporary storage area 4, the second cleaning brush 902 cleans the filter screen 1.

[0160] During the process of the filter screen 1 moving from the dust removal area 2 to the temporary storage area 4, the second cleaning brush cleans the filter screen 1, improving the cleanliness of the filter screen 1. Since the first cleaning brush 901 cleans the filter screen 1 in a single direction (i.e., from top to bottom) and the second cleaning brush 902 itself does not move while the filter screen 1 moves, the cleaning direction of the second cleaning brush 902 on the filter screen 1 is opposite to that of the first cleaning brush 901 on the filter screen 1. Thus, the cleanliness of the filter screen 1 is further improved.

[0161] Preferably, step eleven further includes: when the filter screen 1 moves from the dust removal area 2 to the filtration area 3, the first cleaning brush 901 moves towards the filter screen 1 and presses the filter screen 1.

[0162] During the process of the filter screen 1 moving from the dust removal area 2 to the filtration area 3, the filter screen 1 will pass above the storage box 903, and the filter screen 1 may be re-contaminated by the dust in the storage box 903 when passing by (for example, the dust in the storage box 903 is lifted due to gas flow); however, the dust on the filter screen 1 is extremely small due to this contamination, and only the first cleaning brush 901 needs to clean the filter screen 1 again; further improving the cleanliness of the filter screen 1.

[0163] Preferably, the dust removal control method further includes: positioning the filter screen 1 before performing step one.

[0164] When the filter screen 1 is in use, due to human reasons, such as cleaning and maintaining the interior of the indoor unit, the filter screen 1 will move; it may also be that during the use process, the position of the filter screen 1 changes due to reasons such as air flow and vibration; it is necessary to position the filter screen 1 before dust removal; thus making the actual length more accurate when the filter screen 1 moves a preset length towards the dust removal area.

[0165] Preferably, the method for positioning the filter screen is: the filter screen 1 moves towards the filtration area 3 to a preset position.

[0166] First, make the filter screen 1 move towards the filtration area 3 to a preset position to position the filter screen 1. Then, when the filter screen 1 moves a preset length towards the dust removal area 2 by rotating the first motor 801 and the second motor 802 by a certain number of turns, the moving length of the filter screen 1 is more accurate.

[0167] The preset position can be set such that the filter screen 1 is completely in the filtration state. When the second travel switch 102 is provided in the filtration area 3, it can be determined whether the filter screen moves to the preset position by the filter screen 1 triggering the second travel switch 102.

[0168] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
