Description

Technical Field

[0001] The present application relates to but is not limited to the technical field of household appliances, and specifically refers to an air conditioner. Background Art

[0002] During the long-term operation of the air conditioner, dust is easily deposited on the air duct components, so the air duct surface needs to be cleaned regularly. However, the air duct surface is located inside the air conditioner, which is very inconvenient to clean. For traditional air conditioners, such as wall-mounted air conditioners, the cleaning of the air duct surface mostly needs to be done by after-sales personnel using special equipment, which requires a lot of manpower and financial resources. Summary of the invention

[0003] The technical problem to be solved by the present application is to provide an air conditioner which can reduce the difficulty of cleaning the air duct and eliminate the need for after-sales personnel to use a special design for cleaning, thereby saving manpower and financial resources.

[0004] To this end, an embodiment of the present application provides an air conditioner, comprising: a casing, the casing being provided with an opening; a wind wheel, disposed in the casing; an air duct plate, disposed in the casing and spaced relative to the wind wheel, the plate surface of the air duct plate facing the wind wheel forming an air duct surface, and the air duct plate is movably connected to the casing and is configured to be at least partially able to extend out of the casing or retract into the casing through the opening; and a cleaning device, disposed on the movement path of the air duct plate, configured to clean the air duct surface during the movement of the air duct plate relative to the casing.

[0005] The air conditioner provided in the embodiment of the present application is designed with the air duct plate and the casing as a split structure, and the air duct plate can move relative to the casing. During normal use of the air conditioner, the air duct plate is located inside the casing, that is, in the working position, and can guide the airflow through the air duct surface to realize the air duct function. When the air duct needs to be cleaned, the air duct plate can move relative to the casing, at least partially extending outward from the opening of the casing, so that the air duct plate moves to the cleaning position. During the movement of the air duct plate relative to the casing, the cleaning device can clean the air duct surface. Since the air duct plate is at least partially located outside the casing when it is in the cleaning position, the user can intuitively see the cleaning effect of the air duct surface.

[0006] In addition, the user can decide the number of cleaning times of the air duct plate according to the cleaning effect of the cleaning device on the air duct surface. When the air duct plate moves to the cleaning position for the first time and the cleaning effect is relatively ideal, the cleaning process can be ended. When the cleaning effect of the air duct plate is not ideal after one cleaning, the cleaning effect can be improved by cleaning it multiple times, so that the cleaning of the air duct surface is more thorough, and the cleaning effect can be intuitively seen by the user.

[0007] In addition, when the air duct plate moves to the cleaning position, the air duct plate is at least partially located outside the housing, and manual cleaning is also convenient. Therefore, the user can also choose to manually clean the air duct plate, so that the air duct surface is cleaned more thoroughly, and the cleaning effect can be intuitively seen by the user.

[0043] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0044] In traditional designs, the air duct components are fixed inside the casing, and after-sales personnel need to use special equipment to clean the air duct surface. In addition, during the cleaning process, the air conditioner often needs to be disassembled, such as the panel, frame, heat exchanger and other components, so that the air duct components can be exposed before the air duct surface can be cleaned. The entire cleaning operation process is cumbersome and complicated, and consumes a lot of manpower and financial resources.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the embodiment of the present application provides an air conditioner, comprising: a housing 1, a wind wheel 2, an air duct plate 3 and a cleaning device 4. The air conditioner may also include components such as a heat exchanger 6.

[0046] The housing 1 is provided with an opening. The opening allows one end of the air duct plate 3 to enter and exit the housing 1, so that the air duct plate 3 can be at least partially extended from the housing 1 in a cleaning position (such as Figure 2 , Figure 4 , Figure 5 and Fig.13 ) and the working position of the retracted housing 1 (as shown Figure 1 , Figure 3 , Figure 6 and Fig.11 as shown).

[0047] The wind wheel 2 is located in the casing 1. The wind wheel 2 rotates to draw air into the casing 1, and after exchanging heat with the heat exchanger 6, the air is discharged from the casing 1. The wind wheel 2 may be, but is not limited to, a crossflow wind wheel 2.

[0048] The air duct plate 3 is arranged in the housing 1. One side of the air duct plate 3 forms an air duct surface 31. The air duct surface 31 surrounds a portion of the air duct. In addition, the air duct plate 3 is movably connected to the housing 1 and is arranged so that at least a portion of the air duct plate 3 can extend out of the housing 1 through the opening (e.g., Figure 2 , Figure 4 , Figure 5 and Fig.13 as shown) or retract the housing 1 (as shown Figure 1 , Figure 3 , Figure 6 and Fig.11 shown).

[0049] The cleaning device 4 is disposed on the movement path of the air duct plate 3 , and is configured to clean the air duct surface 31 when the air duct plate 3 moves relative to the housing 1 .

[0050] The air conditioner provided in the embodiment of the present application is designed with the air duct plate 3 and the casing 1 as a split structure, and the air duct plate 3 can move relative to the casing 1. During normal use of the air conditioner, the air duct plate 3 is located inside the casing 1, that is, in the working position, and the airflow can be guided by the air duct surface 31 to realize the air duct function. When the air duct needs to be cleaned, the air duct plate 3 can move relative to the casing 1, at least partially extending outward from the opening of the casing 1, so that the air duct plate 3 moves to the cleaning position. During the movement of the air duct plate 3 relative to the casing 1, the cleaning device 4 can clean the air duct surface 31. Since the air duct plate 3 is at least partially located outside the casing 1 when it is in the cleaning position, the user can intuitively see the cleaning effect of the air duct surface 31.

[0051] Furthermore, the user can determine the number of cleaning times of the air duct plate 3 according to the cleaning effect of the cleaning device 4 on the air duct surface 31. When the air duct plate 3 moves to the cleaning position for the first time and the cleaning effect is relatively ideal, the cleaning process can be ended. When the cleaning effect of the air duct plate 3 is not ideal after one cleaning, the cleaning effect can be improved by cleaning multiple times, so that the cleaning of the air duct surface 31 is more thorough, and the cleaning effect can be intuitively seen by the user.

[0052] In addition, when the air duct plate 3 moves to the cleaning position, the air duct plate 3 is at least partially located outside the housing 1, and manual cleaning is also convenient. Therefore, the user can also choose to manually clean the air duct plate 3, so that the cleaning of the air duct surface 31 is more thorough, and the cleaning effect can be intuitively seen by the user.

[0053] In some exemplary embodiments, the opening is an air outlet 13 .

[0054] In other words, the air duct plate 3 can enter and exit the casing 1 for cleaning through the air outlet 13 of the air conditioner, without the need to provide an additional opening for the air duct plate 3 to enter and exit the casing 1. This can reduce the number of openings in the casing 1, which is beneficial to improving the strength of the casing 1 and reducing air leakage in the casing 1, thereby ensuring the air outlet efficiency of the air conditioner.

[0055] In some exemplary embodiments, the air duct plate 3 is slidably connected to the housing 1. The housing 1 is provided with a guide portion, which is configured to guide the air duct plate 3 to slide relative to the housing 1.

[0056] The provision of the guide portion can make the movement of the air duct plate 3 relative to the housing 1 smoother, and is less likely to get stuck or even stuck, which is beneficial to improving the reliability of the air conditioner.

[0057] In some exemplary embodiments, the guide portion includes a guide groove 14, such as Fig.13 The guide groove 14 extends along the circumferential direction of the air duct surface 31, and the air duct plate 3 is partially limited in the guide groove 14 and can slide along the guide groove 14. The air duct surface 31 has a certain curvature, so the circumferential direction of the air duct surface 31 is the curved direction of the air duct surface 31, as shown in FIG. Fig.13 shown.

[0058] In this way, the structures of the guide part and the air duct plate 3 are relatively simple, which is convenient for processing and forming, and also convenient for assembling the air duct plate 3 and the casing 1 .

[0059] Moreover, the plug-in fit between the guide groove 14 and the air duct plate 3 can be achieved in this way. On the basis of achieving the guiding function, it can also limit the air duct plate 3, which is beneficial to ensure the stability and reliability of the air duct plate 3 in the working position.

[0060] In some embodiments, the number of the guide grooves 14 is at least two, and the two guide grooves 14 are spaced apart along the length direction of the air duct plate 3 .

[0061] The two ends of the air duct plate 3 in the length direction may be inserted into the corresponding guide grooves 14. This is conducive to simplifying the structure of the air duct plate 3, and can limit the contour of the air duct plate 3, which is conducive to improving the stability of the position of the air duct plate 3.

[0062] Alternatively, the air duct plate 3 is provided with a guide protrusion, and the guide protrusion is inserted into the corresponding guide groove 14 .

[0063] In some exemplary embodiments, the housing 1 includes a face frame 11 and a chassis 12 connected to the face frame 11. Figure 1 , Figure 2 and Figure 5 The air duct plate 3 is movably connected to the chassis 12.

[0064] In the conventional design, the air duct component is fixed to the chassis 12. Therefore, movably connecting the air duct plate 3 to the chassis 12 is beneficial to reducing the modification of the housing 1.

[0065] In some embodiments, the guide portion is disposed on the chassis 12 .

[0066] Regarding the formation of the guide groove 14, it can be that: the chassis 12 includes a first support plate 121 and a side plate 124, such as Fig.13 The side plate 124 is provided with a guide rib 15 , and the guide rib 15 and the first support plate 121 enclose a guide groove 14 ; the guide groove 14 may also be formed by partially thinning the side plate 124 of the chassis 12 .

[0067] In some exemplary embodiments, Figure 3 As shown, a support portion 16 is disposed in the housing 1 . The cleaning device 4 is disposed opposite to the support portion 16 . The air duct plate 3 is sandwiched between the support portion 16 and the cleaning device 4 , and the air duct plate 3 is movably connected to the support portion 16 and supported by the support portion 16 .

[0068] In this way, when the air duct plate 3 moves relative to the housing 1, the cleaning device 4 can move relative to the air duct surface 31 to achieve friction, thereby achieving a wiping cleaning effect. In this way, the cleaning device 4 can remain stationary, which is conducive to simplifying the structure and principle of the cleaning device 4 and has high reliability.

[0069] In some exemplary embodiments, the support portion 16 is provided with an avoidance groove 122, such as Figure 3 and Figure 4 The cleaning device 4 is at least partially located in the avoidance groove 122 and is pressed against the air duct surface 31 .

[0070] In this way, the extent to which the cleaning device 4 protrudes from the air duct plate 3 can be minimized, thereby helping to reduce the resistance of the cleaning device 4 to the airflow, thereby helping to reduce the wind resistance of the air conditioner and reducing the negative impact on the air outlet efficiency of the air conditioner; it is also helpful to reduce the adverse effect of the outlet airflow on the cleaning device 4, thereby helping to improve the position stability and use reliability of the cleaning device 4.

[0071] On the other hand, a part of the air duct plate 3 can be located in the avoidance groove 122 and pressed by the cleaning device 4, so that the cleaning device 4 can also fix the air duct plate 3, which is beneficial to prevent the air duct plate 3 from warping, deformation, etc., thereby helping to improve the stability and reliability of the air duct plate 3, and can also simplify the fixing structure of the air duct plate 3.

[0072] In some exemplary embodiments, based on the air duct plate 3 being retracted into the housing 1, the cleaning device 4 is smoothly connected to the portion of the air duct surface 31 outside the avoidance groove 122, such as Figure 3 , Figure 6 shown.

[0073] This can further reduce the impact of the cleaning device 4 on the air flow, which is beneficial to further improve the air outlet efficiency of the air conditioner, and is also beneficial to improving the position stability and use reliability of the cleaning device 4.

[0074] In some exemplary embodiments, the side wall of the avoidance groove 122 is provided with a guide slope 123, such as Fig.12 As shown, the guide slope 123 is configured to guide the air duct plate 3 to enter and exit the avoidance groove 122.

[0075] This helps to prevent the air duct plate 3 from getting stuck in the avoidance groove 122 during movement, thereby helping to improve the smoothness of the movement of the air duct plate 3.

[0076] A first inclined surface may also be correspondingly provided at one end of the cleaning device 4 away from the outlet, so as to improve the smoothness of the air duct plate 3 being retracted inwardly into the casing 1 .

[0077] A second inclined surface may also be correspondingly provided at one end of the air duct plate 3 away from the outlet, so as to improve the smoothness of the air duct plate 3 being retracted inwardly into the casing 1 .

[0078] In some exemplary embodiments, Figure 3 , Figure 4 As shown, the housing 1 includes a face frame 11 and a chassis 12 connected to the face frame 11. The chassis 12 includes a first support plate 121, as shown in FIG. Fig.12 As shown, the face frame 11 includes a second support plate 122. The support portion 16 includes a first support plate 121 and a second support plate 122. The second support plate 122 is staggered with the first support plate 121 to form an avoidance groove 122, as shown in FIG. Fig.12 shown.

[0079] like Fig.12 As shown, the position of the second support plate 122 can be slightly lower than the first support plate 121, so that a step is formed between the first support plate 121 and the second support plate 122, and the internal space of the step is the avoidance groove 122. In this way, the avoidance groove 122 is formed by the cooperation of the chassis 12 and the face frame 11, and can be formed by the structure of the chassis 12 and the face frame 11 itself, without the need to separately process the avoidance groove 122. The above-mentioned guide slope 123 can be set on the end surface of the first support plate 121, such as Fig.12 shown.

[0080] In some exemplary embodiments, the cleaning device 4 is disposed in the housing 1 and is located at the opening, such as Figure 3 and Figure 4 shown.

[0081] In this way, when the air duct plate 3 moves from the working position to the cleaning position, the air duct surface 31 can basically pass through the cleaning device 4, which is conducive to the cleaning device 4 to fully clean the air duct surface 31.

[0082] In some exemplary embodiments, Fig.12 As shown, based on the air duct plate 3 moving to the cleaning position, one end of the air duct plate 3 in the circumferential direction (also the width direction) is located in the avoidance groove 122, and the air duct plate 3 is against the cleaning device 4.

[0083] This helps to reduce the movement amplitude of the air duct plate 3 and also helps to reduce the risk of the air duct plate 3 being separated from the casing 1 .

[0084] Of course, the air duct plate 3 can also be removed from the casing 1 for cleaning, maintenance or replacement as needed.

[0085] In some exemplary embodiments, the air duct plate 3 is a flexible member.

[0086] In this way, during the movement of the air duct plate 3 relative to the casing 1, the air duct plate 3 can undergo elastic deformation, which is beneficial to reduce the risk of the air duct plate 3 getting stuck or even stuck during the movement, thereby helping to improve the smoothness of the air duct plate 3 during the movement.

[0087] Furthermore, the air duct plate 3 can also maintain a suitable shape under the limiting effect of the casing 1 to ensure a good air guiding effect.

[0088] In some embodiments, the air duct plate 3 is a flexible plastic member.

[0089] For a solution in which the housing 1 includes a face frame 11 and a bottom chassis 12 , the support portion 16 may be a part of the bottom chassis 12 .

[0090] In some exemplary embodiments, the cleaning device 4 includes: a cleaning member 41 and a supporting member 42, such as Figure 7 and Fig.12 shown.

[0091] The cleaning member 41 is disposed opposite to the air duct surface 31 and is configured to wipe and clean the air duct surface 31. The supporting member 42 is mounted on the housing 1. The cleaning member 41 is fixed to the supporting member 42.

[0092] The cleaning device 4 includes a cleaning member 41 and a supporting member 42. The cleaning member 41 can rub against the air duct surface 31 of the air duct plate 3 to achieve a wiping and cleaning effect on the air duct surface 31. The cleaning member 41 can be, but is not limited to, a flexible cleaning member such as a cleaning cloth or a cleaning sponge.

[0093] The support member 42 is a mounting carrier for the cleaning member 41. The support member 42 can support and fix the cleaning member 41, ensuring that the cleaning member 41 can effectively rub against the air duct surface 31 to achieve effective cleaning.

[0094] In some exemplary embodiments, the support member 42 is a plate-like structure, such as Figure 7 and Figure 8 shown.

[0095] The support member 42 adopts a plate-like structure, which is simple in structure, easy to process and shape, and also easy to install.

[0096] In some exemplary embodiments, the cleaning member 41 is adhered to the supporting member 42 .

[0097] The cleaning member 41 is fixed to the support member 42 by gluing, which is convenient to operate and does not generate large stress, which is beneficial to the position stability and reliability of the cleaning member 41. In addition, this is also beneficial to simplifying the structure of the support member 42 and preventing adverse scratches on the air duct surface 31.

[0098] Of course, the cleaning member 41 can also be fixed to the support member 42 in other ways, such as by clamping. For example, a rotatable clamping plate is provided on the cleaning member 41, and when the cleaning member 41 is installed in place, the clamping plate is turned to clamp a part of the cleaning member 41, and the cleaning member 41 is clamped on the support member 42.

[0099] In some exemplary embodiments, the support member 42 is provided with a hook portion 424, such as Figure 8 The hook portion 424 hooks the support member 42 to prevent the cleaning member 41 from escaping from the housing 1 along with the air duct plate 3. Fig.12 shown.

[0100] The hook portion 424 is relatively located outside, which can limit the cleaning member 41 and prevent the cleaning member 41 from moving outward with the air duct plate 3 under the friction of the air duct plate 3 and falling out of the housing 1. This is conducive to improving the stability and reliability of the cleaning member 41. The hook portion 424 does not need to be provided on the inner side of the support member 42, because the cleaning member 41 is not easy to fall out of the avoidance groove 122 due to the groove wall restriction of the avoidance groove 122.

[0101] In some exemplary embodiments, the support member 42 is detachably connected to the housing 1 .

[0102] In this way, after the cleaning device 4 has been used for a period of time, the cleaning device 4 can be disassembled and the cleaning member 41 can be cleaned, which is beneficial to ensure the cleaning effect of the cleaning device 4 on the air duct plate 3 during long-term use.

[0103] In some exemplary embodiments, one end of the support member 42 is plug-fitted with the housing 1, and the other end of the support member 42 is snap-fitted with the housing 1, such as Fig.10 and Fig.12 shown.

[0104] During assembly, one end of the support member 42 is inserted into the corresponding position of the housing 1, and the other end of the support member 42 is clamped on the housing 1, so that the cleaning device 4 and the housing 1 can be assembled, which is very convenient. During disassembly, one only needs to release the clamping connection between the support member 42 and the housing 1, and then pull out the support member 42, which is also convenient.

[0105] It can be, for example Fig.10 and Fig.12 As shown, the housing 1 is provided with a first slot 181 and a card slot 17 , one end of the support member 42 is provided with an insert tongue 421 , and the other end is provided with a buckle 422 , the insert tongue 421 is plug-fitted with the first slot 181 , and the buckle 422 is snap-fitted with the card slot 17 .

[0106] Of course, the positions of the first slot 181 and the inserting tongue 421 can be swapped, and the positions of the buckle 422 and the slot 17 can also be swapped.

[0107] In some exemplary embodiments, one end of the support member 42 having the inserting tongue 421 is also provided with an avoidance groove 423, such as Figure 8 As shown, the inserting tongue 421 is protruded on the groove wall of the avoiding groove 423 .

[0108] like Fig.12 As shown, the housing 1 is provided with a second slot 182 , and one end of the support member 42 provided with an inserting tongue 421 is at least partially embedded in the second slot 182 and supported by the housing 1 .

[0109] This ensures the stability and reliability of one end of the support member 42, which will not fall downward or move up and down or forward and backward.

[0110] like Figure 8 and Fig.12 As shown, the inserting tongue 421 may be roughly rectangular, and the first slot 181 may be correspondingly rectangular, so that the inserting tongue 421 may be entirely located in the first slot 181 and supported and limited by the slot wall of the first slot 181 .

[0111] The second slot 182 may be a strip-shaped slot with an open outer end, so that one end of the support member 42 provided with the inserting tongue 421 may be partially inserted into the second slot 182 and partially located outside the second slot 182. Fig.12 As shown, the portion outside the second slot 182 can be aligned with the face frame 11 .

[0112] In some exemplary embodiments, Figure 5 As shown, the air conditioner further includes: a driving device 5 connected to the air duct plate 3 and configured to drive the air duct plate 3 to move relative to the casing 1.

[0113] In this way, the air duct plate 3 can be automatically moved, and then the air duct plate 3 can be self-cleaned. The entire cleaning process does not require manual operation by the user, which is beneficial to improving the user experience and the market competitiveness of the product.

[0114] Of course, the air conditioner may not include the driving device 5 , and the user may also manually drive the air duct plate 3 to move, thereby cleaning the air duct plate 3 .

[0115] In some exemplary embodiments, Figure 6 , Fig. 9 and Fig.10 As shown, the driving device 5 includes: a driving member 51 and a transmission assembly.

[0116] The driving member 51 is mounted on the housing 1 . The transmission assembly is connected to the driving member 51 and to the air duct plate 3 , and is configured to drive the air duct plate 3 to move under the driving of the driving member 51 .

[0117] The driving member 51 is a power source, providing power for the reciprocating motion of the air duct plate 3. The driving member 51 can be, but is not limited to, a motor.

[0118] The transmission assembly is a transmission mechanism between the driving member 51 and the air duct plate 3, which can convert the motion form of the driving plate into the motion form of the air duct plate 3 to drive the air duct plate 3. The transmission assembly can be, but is not limited to, a gear transmission mechanism.

[0119] In some exemplary embodiments, Figure 6 , Fig. 9 and Fig.10As shown, the transmission assembly includes a first transmission gear 52, a connecting shaft 54 ​​and a second transmission gear 53. The first transmission gear 52 is connected to the driving member 51, and the two ends of the connecting shaft 54 ​​are respectively fixedly connected to the first transmission gear 52 and the second transmission gear 53. The plate surface of the air duct plate 3 facing away from the air duct surface 31 is provided with a rack 32, and the first transmission gear 52 and the second transmission gear 53 are both meshed with the rack 32.

[0120] The first transmission gear 52 and the second transmission gear 53 are both meshed with the air duct plate 3, and the first transmission gear 52 and the second transmission gear 53 are both output gears. The first transmission gear 52 is directly connected to the driving member 51, and the first transmission gear 52 is also an input gear. The connecting shaft 54 ​​connects the first transmission gear 52 and the second transmission gear 53, and transmits the power of the first transmission gear 52 to the second transmission gear 53.

[0121] The connecting shaft 54 ​​and the first transmission gear 52 and the second transmission gear 53 can be an integrated structure or a split assembly structure. The connecting shaft 54 ​​can be a solid columnar structure or a hollow cylindrical structure. For example, the connecting shaft 54 ​​is a hollow cylindrical structure, and the first transmission gear 52 and the second transmission gear 53 are both provided with cylindrical protrusions, which are interference fit with the connecting shaft 54 ​​to achieve fixed connection.

[0122] Of course, the transmission assembly may also include an intermediate gear.

[0123] In some exemplary embodiments, the rack 32 extends to both ends of the air duct plate 3 along the length direction of the air duct plate 3. Fig.13 shown.

[0124] In this way, the rack 32 plays a role in cooperating with the driving device 5 to realize the driving, and can also serve as a reinforcing rib to prevent the air duct plate 3 from deforming along the length direction, which is conducive to improving the stability and reliability of the air duct plate 3 during use. In addition, the thickness of the rack 32 is relatively small, which will not affect the deformation of the air duct plate 3 in the thickness direction, so that the air duct plate 3 is easy to deform flexibly in the thickness direction to improve the smoothness of the air duct plate 3 during movement.

[0125] In some exemplary embodiments, a support portion 16 is provided in the housing 1, and the air duct plate 3 is movably connected to the support portion 16 and supported by the support portion 16. The transmission assembly is located on a side of the support portion 16 away from the air duct plate 3.

[0126] The support portion 16 is provided with an escape notch, and the escape notch is configured to escape the first transmission gear 52 and the second transmission gear 53 so that the first transmission gear 52 and the second transmission gear 53 are meshed with the rack 32 .

[0127] The avoidance gap can be set on the second support plate 111 of the face frame 11. In this way, the second support plate 111 can support the air duct plate 3, but will not affect the meshing of the first transmission gear 52, the second transmission gear 53 and the rack 32.

[0128] In some exemplary embodiments, Fig.10 As shown, the housing 1 is provided with a first mounting plate 18 and a second mounting plate 19 which are arranged opposite to each other. The transmission assembly and the cleaning device 4 are located between the first mounting plate 18 and the second mounting plate 19 and are mounted on the first mounting plate 18 and the second mounting plate 19. The driving member can also be mounted on the first mounting plate 18.

[0129] The first slot 181 and the second slot 182 may be provided on the first mounting plate 18, and the card slot 17 may be provided on the second mounting plate 19. The first mounting plate 18 and the second mounting plate 19 may be an integrated structure with the chassis 12.

[0130] In some exemplary embodiments, the air duct plate 3 includes a plurality of sub-plates 33 (such as Figure 2 As shown), multiple sub-plates are arranged along the length direction of the air duct plate 3. Figure 2 , Figure 7 Only one sub-plate 33 is shown in the figure, and the other sub-plates 33 are not shown. You can refer to the sub-plate 33 shown in the figure for understanding. The multiple sub-plates 33 can move synchronously for cleaning, or they can move separately for cleaning. The length direction of the air duct plate 3 is consistent with the axial direction of the wind wheel 2.

[0131] Accordingly, the number of cleaning devices 4 can be one, that is, one cleaning device 4 can clean multiple sub-boards 33 at the same time. The number of cleaning devices 4 can also be multiple, and multiple cleaning devices 4 correspond to multiple sub-boards 33 one by one (or not one by one, there can be a one-to-many situation), and clean the corresponding sub-boards 33 respectively.

[0132] Similarly, the number of driving devices 5 can be one, that is, one driving device 5 can drive multiple sub-boards 33 to move simultaneously. The number of driving devices 5 can also be multiple, and multiple driving devices 5 correspond to multiple sub-boards 33 one by one (or not one by one, there can be a one-to-many situation), respectively driving the corresponding sub-boards 33 to move.
