Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner with a reversible air outlet and a control method thereof. Background Art

[0002] With the improvement of people's living standards, air conditioners are widely used in daily life, and users have higher and higher requirements for the overall performance of air conditioners, especially for the comfort and filter cleaning functions of air conditioners. The existing wall-mounted air conditioner indoor unit mainly adopts the form of cross-flow fan blades and lower air outlets, which realizes the functions of cooling without direct blowing and heating on the ground, usually by changing the structure of the air guide plate. However, the change of the air supply direction by the air guide plate cannot solve the air supply effect of the air conditioner well. The space limitation leads to low air volume, and it is difficult to further improve the comfort. In order to overcome the aforementioned deficiencies in the prior art, a cabinet air conditioner with reversible air outlets has appeared in the prior art, which has an upper air outlet located above the air conditioner and a lower air outlet located below the air conditioner, and when one of the upper and lower air outlets is used as an air inlet, the other is used as an air outlet, so that it can correspond to the hot air flow and cold air flow in the heating and cooling modes of the air conditioner, thereby realizing carpet-style air outlet in the heating mode and shower-style air outlet in the cooling mode. Since the upper and lower air outlets of this type of air conditioner can both be used as air inlets, it is necessary to respectively configure filters for the upper and lower air outlets so as to filter the incoming air flow when they are used as air inlets. This method of separately configuring filters for each air outlet makes the structure of the air conditioner relatively complicated on the one hand, and on the other hand, the configuration of the self-cleaning device for the filter also needs to configure multiple sets, which makes the structure and control logic of the air conditioner further complicated. Summary of the invention

[0003] Therefore, the present invention provides an air conditioner with reversible air vents and a control method thereof, which can overcome the technical problem in the related art that the air vents of the air conditioner with reversible air vents need to be respectively configured with filters, making the structural design of the air conditioner relatively complicated.

[0004] In order to solve the above-mentioned problem, the present invention provides an air conditioner with a reversible air outlet, comprising an air conditioner shell, on which an upper air outlet and a lower air outlet are constructed, and a filter net is provided in the air conditioner shell, the filter net having a first filtering position located in the upper air outlet to filter the incoming air flow of the upper air outlet and a second filtering position located in the lower air outlet to filter the incoming air flow of the lower air outlet, and the filter net can be driven to switch between the first filtering position and the second filtering position to realize the sharing of the filter net by the upper air outlet and the lower air outlet.

[0005] In some embodiments, the air conditioner casing has a front panel facing the user side, and the front panel is a detachable structure, the filter screen also has an initial position, the filter screen can be driven to switch between the initial position, the first filtering position and the second filtering position, and when the filter screen is in the initial position, the filter screen is on the inner side of the front panel; and / or, the upper air outlet is provided with an upper air guide plate capable of closing it, and the lower air outlet is provided with a lower air guide plate capable of closing it.

[0006] In some embodiments, the air conditioner also includes an air conditioning frame, the air conditioning shell is assembled on the air conditioning frame, the filter is slidably connected to the air conditioning frame so that the filter can switch between the initial position, the first filtering position and the second filtering position in a sliding manner, and the filter is located between the air conditioning frame and the air conditioning shell.

[0007] In some embodiments, the air conditioning frame has two U-shaped rails arranged in parallel and at intervals, the filter screen is a flexible filter screen, and the width sides of the filter screen are respectively slidably connected to the U-shaped rails. The air conditioning frame is also provided with a driving device, and the driving device has a rotating shaft that engages with the filter screen to drive the filter screen to slide back and forth along the guiding direction of the U-shaped rail.

[0008] In some embodiments, the rotating shafts include two rotating shafts that are arranged in parallel and spaced apart, each rotating shaft is arranged corresponding to a corner position of the U-shaped track, and both rotating shafts are located on the inner side of the filter screen.

[0009] In some embodiments, a filter cleaning device is further provided in the air conditioner casing, and the filter cleaning device has a filter cleaning piece. The rotating shaft arranged near the downwind outlet and the filter cleaning piece are respectively located on both sides of the sliding path of the filter, and the bristles of the filter cleaning piece can flexibly interfere with the filter.

[0010] In some embodiments, the rotating shaft arranged near the downwind outlet is located above the filter cleaning piece, and a dust box is provided in the lower area of ​​the filter cleaning piece, and the dust box is used to collect dirty dust scattered in the upper area thereof, and the dust box can be detachably assembled in the air conditioner casing.

[0011] In some embodiments, a water receiving tray is further provided in the air conditioner casing, and the rotating shaft arranged near the downwind outlet and the filter cleaning device are both located below the water receiving tray, so that the water receiving tray can be used to shield the dirt and dust generated during the operation of the filter cleaning device.

[0012] In some embodiments, the bristles are in the shape of long strips, and the length of the long strips is not less than the width of the filter; and / or, the filter cleaning device also includes a bristle cleaning piece, and the bristles have a filter cleaning position capable of contacting the filter and a bristle self-cleaning position capable of contacting the bristle cleaning piece, and the filter cleaning piece can be controlled to rotate so that the bristles switch between the filter cleaning position and the bristle self-cleaning position, and the bristle cleaning piece can at least partially scrape off the dirt adhering to the bristles when the bristles are in the bristle self-cleaning position.

[0013] In some embodiments, the air conditioner is a wall-mounted air conditioner.

[0014] The present invention also provides a control method for the air conditioner as described above, comprising the following steps:

[0015] Get the operating mode of the air conditioner;

[0016] When the acquired operation mode is the cooling mode, the filter is controlled to move to the upper air outlet to filter the airflow from the upper air outlet; or,

[0017] When the acquired operation mode is the heating mode, the filter is controlled to move to the downwind port to filter the incoming air flow of the downwind port.

[0018] In some embodiments, when the air conditioner includes a filter cleaning device, and the filter cleaning device includes a filter cleaning member:

[0019] When the air conditioner receives a stop command during operation in the cooling mode, the filter is controlled to move from the upper air outlet toward the lower air outlet so as to clean the filter with the filter cleaning member, and during the cleaning process, the filter cleaning member is controlled to always be in the filter cleaning position; or

[0020] When the air conditioner receives a shutdown command during operation in the heating mode, the filter is controlled to move from the downwind port toward the upwind port so as to use the filter cleaning member to clean the filter, and during the cleaning process, the filter cleaning member is controlled to always be in the filter cleaning position.

[0021] In some embodiments, when the filter screen cleaning device further includes a brush cleaning member, after the filter screen is cleaned, the following steps are further included:

[0022] The filter cleaning member is controlled to rotate to switch between the filter cleaning position and the bristle self-cleaning position.

[0023] In some embodiments, when the filter screen has an initial position, after the filter screen is cleaned, the following steps are further included:

[0024] The filter screen is controlled to move to the initial position.

[0025] The air conditioner with reversible air vents and the control method thereof provided by the present invention have the following beneficial effects:

[0026] Based on the situation that the air outlets of the upper air outlet and the lower air outlet can be used reversibly, only one filter is set in the air conditioner shell and is shared by the upper air outlet and the lower air outlet. When one of the two air outlets is used as an air inlet and the other as an air outlet, the filter is controlled to move to the air outlet position as the air inlet to filter the incoming air flow. There is no need to set a filter for each air outlet separately, which reduces the number of filter configurations, thereby simplifying the internal structure design of the air conditioner and reducing the manufacturing cost of the air conditioner to a certain extent.

[0027] When the filter is in the initial position, the filter is located on the inner side of the front panel, that is, the initial position of the filter is the position corresponding to the aforementioned window area. This arrangement allows the user to easily remove the filter from the air conditioner housing from this position when the filter needs to be thoroughly cleaned (washed) or repaired.

[0028] The filter is slidably connected to the air conditioner frame, so that the position switching of the filter is more reliable and stable. Objectively, the filter slides between the air conditioner frame and the air conditioner shell, which can effectively improve the utilization rate of the internal space of the air conditioner, ensure the compact design of the air conditioner structure, and is conducive to the miniaturization design of the air conditioner.

[0029] The rotating shaft is arranged on the inner side of the filter, so that when the user removes the filter, the operation can be realized in front of the air conditioner, which facilitates the disassembly and assembly process of the filter. Specifically, when the user needs to take out the filter from the air conditioner, the front panel is opened, and the filter in the initial position is completely in front of the user. The rack on the inner side of the filter meshes with the rotating shaft from the inner side thereof, and the two ends of the filter are in the U-shaped track. At the same time, the filter is a filter with a certain flexibility. The user only needs to slightly pull it outward to take out the filter, and the assembly operation can be reversed, which is very convenient.

[0030] By forming a flexible resistance between the filter cleaning member disposed on the outside of the filter and the filter, when the filter is controlled to switch positions and slides through the filter cleaning member, the bristles will clean the filter in the process to ensure timely cleaning of the filter. It should be noted that since the cleaning process of the filter occurs during the position switching process of the filter, the filter cleaning member can achieve timely cleaning of the filter by its bristles without actively rotating;

[0031] The rotating shaft and the filter cleaning device in the lower area of ​​the air conditioner are arranged below the water receiving tray, and the dust released during the filter cleaning process can be physically blocked by the water receiving tray in a small area where the dust collecting box is located, so as to prevent the dust from escaping into the air conditioner. For details, see the figure. In an embodiment not shown in the figure, corresponding sealing strips are arranged at the edges of the water receiving tray corresponding to the filter position to enhance the effect of the water receiving tray in preventing dust from escaping.

[0032] By further arranging a bristle cleaning piece in the air conditioner casing, the purpose of at least partially scraping off the dirt adhering to the filter cleaning piece can be achieved by switching the rotational position of the filter cleaning piece, thereby achieving the physical self-cleaning purpose of the filter cleaning device and improving the service life of the filter cleaning device.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90° or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] 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. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] See also Figures 1 to 7 As shown, according to an embodiment of the present invention, an air conditioner with a reversible air outlet is provided. In a specific embodiment, the air conditioner is a wall-mounted air conditioner, and the air conditioner includes an air conditioner housing 1, and an upper air outlet 11 and a lower air outlet 12 are configured on the air conditioner housing 1. The upper air outlet 11 and the lower air outlet 12 are specifically configured to guide the supply air flow upward or downward. In a specific embodiment, the upper air outlet 11 and the lower air outlet 12 are respectively configured on the upper and lower opposite sides of the air conditioner housing 1. A filter 2 is provided in the air conditioner housing 1. Specifically, the filter 2 can be located in the flow passage of the outlet air flow of the upper air outlet 11 or the lower air outlet 12 and in the The air conditioner casing 1 can be used as the air filter 2. The filter 2 has a first filtering position (also referred to as an upper filtering position) located in the upper air outlet 11 to filter the incoming air flow of the upper air outlet 11 and a second filtering position (also referred to as a lower filtering position) located in the lower air outlet 12 to filter the incoming air flow of the lower air outlet 12. The filter 2 can be driven to switch between the first filtering position and the second filtering position to achieve the sharing of the filter 2 by the upper air outlet 11 and the lower air outlet 12. A heat exchanger 62 and an axial flow fan 63 are also provided in the air conditioner casing 1. The air conditioner can be supplied with air from the bottom to the top or from the top to the bottom by controlling the rotation direction of the axial flow fan 63.

[0048] In this technical solution, based on the reversible use of the upper air outlet 11 and the lower air outlet 12, only one filter 2 is set in the air-conditioning casing 1 and is shared by the upper air outlet 11 and the lower air outlet 12. When one of the two air outlets is used as an air inlet and the other as an air outlet, the filter 2 is controlled to move to the air outlet position serving as the air inlet to filter the incoming air flow. There is no need to set a separate filter for each air outlet, thereby reducing the number of filters configured, thereby simplifying the internal structure design of the air conditioner and reducing the manufacturing cost of the air conditioner to a certain extent.

[0049] In some embodiments, the air-conditioning casing 1 has a front panel 13 facing the user side, and the front panel 13 is a detachable structure, that is, the aforementioned front panel 13 can be removed from the air-conditioning casing 1. In order to facilitate its disassembly and assembly process, as a preferred embodiment, the front panel 13 adopts a snap-on structure to be conveniently connected to the air-conditioning casing 1. It can be understood that at this time, the area corresponding to the air-conditioning casing 1 and the front panel 13 is the window area, and the filter 2 also has an initial position. The filter 2 can be driven to switch between the initial position, the first filtering position and the second filtering position, and when the filter 2 is in the initial position, the filter 2 is on the inner side of the front panel 13, that is, the initial position of the filter 2 is also the position corresponding to the aforementioned window area. Such a configuration can facilitate the user to easily remove the filter 2 from the air-conditioning casing 1 from this position when the filter 2 needs to be thoroughly cleaned (washed) or repaired. See specifically Figure 1 As shown, the initial position is in the area between the first filtering position and the second filtering position.

[0050] In order to increase the air supply distance of the air flow and make the air supply direction adjustable, thereby improving the comfort of the air conditioner, the upper air outlet 11 is provided with an upper air guide plate 111 capable of closing it, and the lower air outlet 12 is provided with a lower air guide plate 121 capable of closing it. When the air conditioner is in the off state (such as Figure 1 As shown in the figure, the upper air guide plate 111 and the lower air guide plate 121 respectively close the upper air outlet 11 and the lower air outlet 12, which can effectively prevent external dirt and dust from entering the interior of the air conditioner.

[0051] In some embodiments, the air conditioner also includes an air conditioning frame (not shown and not labeled in the figure), and the air conditioning shell 1 is assembled on the air conditioning frame, that is, objectively, the air conditioning frame is an assembly carrier of the air conditioning shell 1 and the internal structure, and the filter 2 is slidably connected to the air conditioning frame so that the filter 2 can switch between the initial position, the first filtering position and the second filtering position in a sliding manner, and the filter 2 is located between the air conditioning frame and the air conditioning shell 1.

[0052] In this technical solution, the filter 2 is slidably connected to the air-conditioning frame, so that the position switching of the filter 2 is more reliable and stable, and objectively, the sliding of the filter 2 is between the air-conditioning frame and the air-conditioning casing 1, which can effectively improve the utilization rate of the internal space of the air conditioner, ensure the compact design of the air-conditioner structure, and is conducive to the miniaturization design of the air conditioner.

[0053] In a specific embodiment, the air conditioning frame has two U-shaped rails 3 arranged in parallel and at intervals. Specifically, the aforementioned U-shaped rail 3 includes an upper guide rail section (not labeled in the figure) arranged in parallel with the upper air outlet 11, a lower guide rail section (not labeled in the figure) arranged in parallel with the lower air outlet 12, and a vertical guide rail section (not labeled in the figure) connected between the upper guide rail section and the lower guide rail section. The connection position between the guide rail sections is a chamfered design. Correspondingly, the filter screen 2 is a flexible filter screen, so that it can be ensured that the filter screen 2 can be easily and smoothly guided through the corner area of ​​the aforementioned U-shaped track 3. The width sides of the filter screen 2 are respectively slidably connected to the U-shaped track 3 to ensure that the entire position of the filter screen 2 is switched to the U-shaped track 3 for reliable guidance. The air conditioning frame is also provided with a driving device (not labeled in the figure). The driving device has a rotating shaft 41 that engages with the filter screen 2 to drive the filter screen 2 to slide back and forth along the guiding direction of the U-shaped track 3. For details, see Figure 5 As shown, a rack 21 is provided at each end position of the width of the filter screen 2, and correspondingly, a corresponding ring gear is provided in the area corresponding to the position of the rotating shaft 41 and each rack 21. The rotating shaft 41 is driven to adjust the position of the filter screen 2 through the engagement of the ring gear and the rack 21. The aforementioned rotating shaft 41 is driven to rotate by a power structure not shown in the figure, such as a rotary motor.

[0054] In some embodiments, the rotating shafts 41 include two rotating shafts 41 that are arranged in parallel and spaced apart from each other. Each rotating shaft 41 is arranged corresponding to a corner position of the U-shaped track 3 , and both rotating shafts 41 are located on the inner side of the filter screen 2 .

[0055] In this technical solution, the rotating shaft 41 is arranged on the inner side of the filter 2, so that when the user removes the filter 2, the operation can be carried out in front of the air conditioner, which facilitates the disassembly and assembly process of the filter 2. Specifically, when the user needs to take out the filter 2 from the air conditioner, the aforementioned front panel 13 is opened. At this time, the filter 2 in the initial position is completely in front of the user, and the rack 21 on the inner side of the filter 2 is engaged with the rotating shaft 41 from its inner side, and the two ends of the filter 2 are in the U-shaped track 3. At the same time, the filter 2 is a filter with a certain flexibility. The user only needs to pull it slightly outward to take out the filter 2, and the assembly operation can be reversed, which is very convenient.

[0056] In some embodiments, a filter cleaning device (not marked in the figure) is further provided in the air-conditioning casing 1, and the filter cleaning device has a filter cleaning piece 51. The rotating shaft 41 arranged near the downwind outlet 12 (that is, the rotating shaft 41 located in the lower area of ​​the air conditioner) and the filter cleaning piece 51 are respectively located on both sides of the sliding path of the filter 2. At this time, it can be understood that the filter cleaning piece 51 is on the outside of the filter 2, and the bristles 511 of the filter cleaning piece 51 can flexibly contact the filter 2.

[0057] In this technical solution, a flexible resistance is formed between the filter cleaning member 51 disposed on the outside of the filter 2 and the filter 2. When the filter 2 is controlled to switch positions and slides through the filter cleaning member 51, the bristles 511 will clean the filter 2 during the process, thereby ensuring timely cleaning of the filter 2. It should be noted that since the cleaning process of the filter 2 occurs during the position switching process of the filter 2, the filter cleaning member 51 at this time can achieve timely cleaning of the filter 2 by the bristles 511 thereon without actively rotating.

[0058] Preferably, the rotating shaft 41 disposed near the downwind outlet 12 is located above the filter cleaning member 51, and a dust collecting box 52 is disposed in the lower area of ​​the filter cleaning member 51. The dust collecting box 52 is used to collect the dirty dust scattered in the upper area thereof. The dust collecting box 52 is detachably assembled in the air conditioner housing 1. For details, see Figure 7 As shown, a card slot 521 is formed on the dust box 52, and correspondingly, a corresponding card strip (not marked in the figure) is provided at a corresponding position in the air conditioner housing 1, such as the aforementioned air conditioner frame, so that the dust box 52 can be loaded and unloaded by pulling along the width direction of the air conditioner, so that active cleaning can be performed when a lot of dirty dust is collected in the dust box 52. In a specific embodiment, the air conditioner can also monitor the amount of dust collected in the dust box 52 in real time (for example, a gravity sensor can be provided in the dust box 52 to monitor the weight of the dirty dust collected therein in real time), and send a corresponding reminder message when the amount of dust collected is large and the user needs to clean it (for example, a corresponding sound and light device is provided on the air conditioner panel).

[0059] In some embodiments, a water receiving pan 61 is further provided in the air-conditioning casing 1, which is located below the heat exchanger 62 and is used to receive condensation water generated by the heat exchanger 62 during use. In a preferred embodiment, the rotating shaft 41 and the filter cleaning device arranged near the downwind outlet 12 are both located below the water receiving pan 61, so that the water receiving pan 61 can be used to shield the dirty dust generated during the operation of the filter cleaning device.

[0060] In this technical solution, the rotating shaft 41 and the filter cleaning device in the lower area of ​​the air conditioner are arranged below the water receiving tray 61. The water receiving tray 61 can be used to physically block the dust released during the cleaning process of the filter 2 in a small area where the dust collecting box 52 is located, thereby preventing the dust from escaping into the air conditioner. For details, see Figure 2 As shown, in an embodiment not shown in the figure, corresponding sealing strips are provided at the edges of the water receiving tray 61 corresponding to the positions of the filter screen 2 to enhance the effect of the water receiving tray 61 in preventing dust from escaping.

[0061] In a specific embodiment, the bristles 511 are in the shape of long strips, and the length of the long strips is not less than the width of the filter screen 2, so as to completely cover the width of the filter screen 2 and achieve comprehensive cleaning of the filter screen 2 without dead ends.

[0062] See also Figure 2 As shown, the filter cleaning device also includes a bristle cleaning member 53, the bristles 511 having a filter cleaning position capable of contacting the filter 2 and a bristle self-cleaning position capable of contacting the bristle cleaning member 53, the filter cleaning member 51 can be controlled to rotate so that the bristles 511 switch between the filter cleaning position and the bristle self-cleaning position, and the bristle cleaning member 53 can at least partially scrape off the dirt adhered to the bristles 511 when the bristles 511 are in the bristle self-cleaning position.

[0063] In this technical solution, a bristle cleaning member 53 is further arranged in the air-conditioning casing 1, so that the filter cleaning member 51 can be switched in rotation position to at least partially scrape off the dirt adhering thereto, thereby achieving the physical self-cleaning purpose of the filter cleaning device and improving the service life of the filter cleaning device.

[0064] In a specific embodiment, the filter cleaning member 51 includes a support frame 512, the support frame 512 is fixedly connected to a drive shaft 513, and the bristles 511 are fixedly connected to the outer surface of the support frame 512. The end of the drive shaft 513 is drivingly connected to a rotary motor. When the rotary motor is running, it will drive the support frame 512 and the bristles 511 thereon to rotate to achieve the position switching of the bristles 511. In order to reduce the weight of the device, the drive shaft 513 and the support frame 512 can be made of aluminum.

[0065] The aforementioned bristle cleaning member 53 may specifically be a comb tooth structure made of metal (with limited adhesion to dirt). The comb tooth structure contacts the soft bristles 511 to comb out and peel off the dirt adhered to the bristles 511, thereby achieving scratch cleaning of the bristles 511.

[0066] According to an embodiment of the present invention, there is also provided a control method for the air conditioner as described above, comprising the following steps:

[0067] Obtaining the operating mode of the air conditioner, the operating mode includes cooling mode and heating mode;

[0068] When the acquired operation mode is the cooling mode, the filter 2 is controlled to move to the upper air outlet 11 to filter the air inlet air flow of the upper air outlet 11, that is, the filter 2 is in the first filtering position. At this time, in order to ensure the air flow direction of the air conditioner from bottom to top, the axial flow fan 63 is controlled to rotate in the first rotation direction (for example, forward rotation). The cold air flow flowing upward has a larger density, thereby achieving a shower-like cooling effect from top to bottom, thereby improving the comfort of the user; or,

[0069] When the acquired operating mode is the heating mode, the filter 2 is controlled to move to the downwind port 12 to filter the incoming air flow of the downwind port 12, that is, the filter 2 is in the second filtering position. At this time, in order to ensure the air flow direction of the air conditioner from top to bottom, the axial flow fan 63 is controlled to rotate in the second direction (for example, reverse rotation). The downward-flowing hot air flow has a lower density, thereby achieving a carpet-like heating effect from bottom to top, thereby improving the user's comfort.

[0070] In this technical solution, the position switching of the filter screen 2 is controlled according to the operating mode of the air conditioner, thereby achieving the purpose of targeted air inlet filtering of the reversible air vent, and the control is simple.

[0071] In some embodiments, when the air conditioner includes a filter cleaning device, and the filter cleaning device includes a filter cleaning member 51:

[0072] When the air conditioner receives a stop command during operation in the cooling mode, the filter 2 is controlled to move from the upper air outlet 11 toward the lower air outlet 12 so as to use the filter cleaning member 51 to clean the filter 2. During the cleaning process, the filter cleaning member 51 is controlled to always be in the filter cleaning position (i.e., the position remains unchanged). The cleaning process can be circulated for multiple times to ensure that the filter 2 is thoroughly cleaned; or,

[0073] When the air conditioner receives a shutdown command during operation in the heating mode, the filter 2 is controlled to move from the downwind port 12 toward the upwind port 11 so that the filter 2 can be cleaned by the filter cleaning member 51. During the cleaning process, the filter cleaning member 51 is controlled to always be in the filter cleaning position (that is, the position remains stationary).
