However, the air deflector of a traditional air conditioner is located at the air outlet position, blocking the air outlet of the air conditioner and affecting the air volume of the air conditioner. Therefore, it is urgent to design an air deflector of an air conditioner that does not affect the air volume of the air conditioner. Summary of the Utility Model

[0003] An object of the utility model is to provide an air deflector of an indoor unit of an air conditioner that does not affect the air volume of the air conditioner during air guiding.

[0004] A further object of the utility model is to simplify the structure of the air deflector of the indoor unit of the air conditioner.

[0005] Another object of the utility model is to provide an indoor unit of an air conditioner having the above air deflector.

[0006] Specifically, the utility model provides an air deflector of an indoor unit of an air conditioner. The indoor unit of the air conditioner includes a housing. A air supply channel is provided inside the housing. The air supply channel has an air outlet for supplying air to the outside. The air deflector includes:

[0007] An air deflector body movably installed at the air outlet. The air deflector body is configured to move from a closed state of covering the air outlet toward the front side or the rear side of the housing during air guiding, and rotate during or after the movement to form an extended state extending toward the downstream direction of the air flow, thereby exposing the air outlet and extending the air guiding distance.

[0008] A driving device respectively connected to the housing and the air deflector body for driving the air deflector body to move and rotate.

[0009] Optionally, the air supply channel is defined by a front wall of the air duct and a rear wall of the air duct. When the indoor unit of the air conditioner is in the maximum air supply state, the air deflector body is configured to rotate and move to a position where the upper end abuts against the rear wall of the air duct under the drive of the driving device to completely expose the air outlet.

[0010] Optionally, the driving device includes:

[0011] At least one first driving component respectively connected to the housing and the air deflector body for controllably driving the air deflector body to move toward the front side or the rear side of the housing to close or expose the air outlet.

[0012] Optionally, a plurality of mounting arms are provided on the air deflector body, and the plurality of mounting arms are arranged along the rotation axis direction of the air deflector body; the driving device further includes:

[0013] A second driving assembly rotatably connected to at least one of the mounting arms to controllably drive the air deflector body to rotate.

[0014] Optionally, the second driving assembly includes a first housing, and the first driving assembly is connected to the first housing; the first driving assembly includes:

[0015] A first motor installed inside the housing;

[0016] A gear connected to the first motor to rotate under the drive of the first motor;

[0017] A rack engaged with the gear, and one end thereof is rotatably connected to the first housing. The rack is configured to move when the gear rotates to drive the air deflector body to move.

[0018] Optionally, the first driving assembly is rotatably connected to the mounting arm of the air deflector body.

[0039] Figure 1 is a schematic structural diagram of the air deflector 30 of the air conditioner indoor unit 100 in a closed state according to an embodiment of the present utility model. Figure 2 is a schematic structural diagram of the air deflector 30 of the air conditioner indoor unit 100 in an open state according to an embodiment of the present utility model. As Figures 1 to 2As shown, in a specific embodiment, the indoor unit 100 of the air conditioner is a wall-mounted indoor unit of the air conditioner. The indoor unit 100 of the air conditioner includes a housing 10, and an air supply channel 20 is provided inside the housing 10. The air supply channel 20 has an air outlet for supplying air to the outside. The air deflector 30 includes an air deflector body 31 and a driving device 32. The air deflector body 31 is movably installed at the air outlet. The air deflector body 31 is configured to move from a closed state where the air outlet is shielded toward the front side or the rear side of the housing 10 during air guiding, and rotate during or after the movement to form an extended state extending toward the downstream direction of the air flow, so as to expose the air outlet and extend the air guiding distance. The driving device 32 is respectively connected to the housing 10 and the air deflector body 31, and is used to drive the air deflector body 31 to move and rotate. Here, when the air deflector body 31 is in the extended state, it can be understood that it extends downward toward the housing 10.

[0040] In some embodiments, the driving device 32 can drive the air deflector body 31 to move from the closed state toward the front side of the housing 10 and rotate during the movement, so that the air deflector body 31 rotates from a horizontal state to a vertical state, forming an extended state extending toward the downstream direction of the air flow, thereby exposing the air outlet and extending the air guiding distance. Here, the air deflector body 31 moves toward the front side of the housing 10 to open the air outlet, and the air deflector body 31 can rotate while moving.

[0041] In some embodiments, the driving device 32 can also drive the air deflector body 31 to move from the closed state toward the front side of the housing 10 and rotate after the movement, so that the air deflector body 31 rotates from a horizontal state to a vertical state, forming an extended state extending toward the downstream direction of the air flow, thereby exposing the air outlet and extending the air guiding distance. Here, the air deflector body 31 moves toward the front side of the housing 10 to open the air outlet, and the air deflector body 31 can rotate after the movement is completed.

[0042] In some embodiments, the driving device 32 can also drive the air deflector body 31 to move from the closed state toward the rear side of the housing 10 and rotate during the movement, so that the air deflector body 31 rotates from a horizontal state to a vertical state, forming an extended state extending toward the downstream direction of the air flow, thereby exposing the air outlet and extending the air guiding distance. Here, the air deflector body 31 moves toward the rear side of the housing 10 to open the air outlet, and the air deflector body 31 can rotate while moving.

[0043] In some embodiments, the driving device 32 can also drive the air deflector body 31 to move from the closed state toward the rear side of the housing 10, and rotate after the movement, so that the air deflector body 31 rotates from the horizontal state to the vertical state, forming an extended state extending toward the downstream direction of the air flow, thereby exposing the air outlet and extending the air guiding distance. Here, the air deflector body 31 moves toward the rear side of the housing 10 to open the air outlet, and the air deflector body 31 can rotate after the movement is completed.

[0044] In this embodiment, not only is the air deflector 30 arranged to be movable, but also the air deflector 30 is arranged to be rotatable, so that the air deflector 30 rotates while or after opening the air outlet, which not only does not affect the air volume of the air conditioner, but also can extend the air guiding distance, thereby reducing the air volume loss and guiding the air output of the air conditioner.

[0045] Figure 3 It is a schematic structural diagram of the air deflector 30 of the indoor unit 100 of the air conditioner according to an embodiment of the present invention in the maximum air supply state. As Figure 3 shown, and referring to Figure 1 and Figure 2 , in this embodiment, the air supply channel 20 is defined by the air duct front wall 21 and the air duct rear wall 22. When the indoor unit of the air conditioner is in the maximum air supply state, the air deflector body 31 is arranged to rotate and move to a position where its upper end abuts against the air duct rear wall 22 under the drive of the driving device 32 to completely expose the air outlet. In this case, the air deflector 30 completely avoids the air outlet, so that the air volume of the air conditioner reaches the maximum. After the air deflector body 31 rotates to the vertical state, its upper end abuts against the air duct rear wall 22, so that the air outlet area of the air outlet is the largest, thereby making the air volume reach the maximum.

[0046] While taking into account the basic functions of the air deflector 30, this embodiment can completely avoid the air deflector 30 from the air outlet, avoiding affecting the air volume. At the same time, the air deflector 30 can also form an extension of the air supply channel 20, reduce the air volume loss, and guide the air output of the air conditioner.

[0047] In this embodiment, the outer shape of the air deflector body 31 is substantially the same as the outer shape of the air duct rear wall 22, so that the air deflector body 31 can abut against the air duct rear wall 22.

[0048] In some embodiments, the air deflector body 31 is further configured to rotate and move to a position where its upper end abuts against the front wall 21 of the air duct under the drive of the drive device 32, so as to expose the air outlet. Here, the outer shape of the air deflector body 31 can be set to be substantially the same as that of the front wall 21 of the air duct, so that the air deflector body 31 can abut against the front wall 21 of the air duct. It can be understood that if the air deflector body 31 moves and rotates from the closed state towards the front side of the housing 10, it can move to a position where its upper end abuts against the front wall 21 of the air duct. If the air deflector body 31 moves and rotates from the closed state towards the rear side of the housing 10, it can move to a position where its upper end abuts against the rear wall 22 of the air duct, and specifically, it can be designed according to design requirements.

[0049] In this embodiment, if the user requires that the air volume of the indoor unit 100 of the air conditioner does not need to be the maximum, then the air deflector body 31 does not need to move to a position where it abuts against the front wall 21 or the rear wall 22 of the air duct, and only needs to move to the middle position of the air outlet, and then rotate to form an extension of the air supply channel 20 and extend the air guiding distance. Refer to Figure 2 .. The moving stroke of the air deflector body 31 can be determined according to the user's needs. The longer the distance that the air deflector body 31 moves from the closed state towards the front side or the rear side of the housing 10, the greater the air volume of the indoor unit 100 of the air conditioner; the shorter the distance that the air deflector body 31 moves from the closed state towards the front side or the rear side of the housing 10, the smaller the air volume of the indoor unit 100 of the air conditioner. The maximum stroke of the air deflector body 31 is the width of the air outlet to ensure that the air deflector body 31 can completely expose the air outlet.

[0050] In this embodiment, the air supply channel 20 formed by the front wall 21 and the rear wall 22 of the air duct gradually widens along the air flow direction, and the size of the air deflector body 31 is adapted to the size of the air outlet to ensure that the air outlet can be completely shielded when in the closed state.

[0051] In this embodiment, the drive device 32 includes at least one first drive assembly 321. The first drive assembly 321 is respectively connected to the housing 10 and the air deflector body 31, and the first drive assembly 321 is used to controllably drive the air deflector body 31 to move towards the front side or the rear side of the housing 10 to close or expose the air outlet. Here, a part of the first drive assembly 321 is installed inside the housing 10, and one end is connected to the air deflector body 31. Whether the air deflector body 31 moves towards the front side of the housing 10 or towards the rear side of the housing 10, the first drive assembly 321 with the same structure can be used.

[0052] In this embodiment, a plurality of mounting arms 311 are provided on the air deflector body 31, and the plurality of mounting arms 311 are arranged along the rotation axis direction of the air deflector body 31. The driving device 32 further includes a second driving component 324, and the second driving component 324 is rotatably connected to at least one mounting arm 311 to controllably drive the air deflector body 31 to rotate. Here, the first rotating shaft 312 passes through the mounting arm 311, and the second driving component 324 is connected to the first rotating shaft 312 passing through the mounting arm 311 and can drive the first rotating shaft 312 to rotate, thereby driving the air deflector body 31 to rotate.

[0053] Figure 4 is a schematic structural diagram of the second driving component 324 in the air deflector 30 according to an embodiment of the present invention. As Figure 4 shown, in this embodiment, the second driving component 324 includes at least one second motor 327, and the second motor 327 is disposed at the end of the air deflector body 31. The second driving component 324 includes two first housings 326, and the two first housings 326 are respectively disposed at the two outermost mounting arms 311 of the air deflector body 31. When the second driving component 324 includes one second motor 327, the second motor 327 is disposed at any end of the air deflector body 31, that is, at one of the outermost mounting arms 311 and is located inside the corresponding first housing 326, and the other first housing 326 is rotatably connected to the corresponding mounting arm 311 through the first rotating shaft 312 to ensure that the second motor 327 can drive the air deflector body 31 to rotate. When the second driving component 324 includes two second motors 327, the two second motors 327 are respectively disposed at the two ends of the air deflector body 31, that is, at the two outermost mounting arms 311 respectively and are located inside the corresponding first housings 326, and the two second motors 327 are set to work synchronously to drive the air deflector body 31 to rotate simultaneously. The number of the second motors 327 can be designed according to specific design requirements.

[0054] Figure 5 is a schematic structural diagram of the air deflector 30 of the indoor unit 100 of an air conditioner according to an embodiment of the present invention. As Figure 5As shown, in this embodiment, the second driving component 324 includes two first housings 326. The number of the first driving components 321 is two, and the two first driving components 321 are respectively connected to the two first housings 326 in a one-to-one correspondence. A second motor 327 is provided inside one of the first housings 326 to drive the air deflector body 31 to rotate. Here, if the air deflector body 31 moves from the closed position towards the rear side of the housing 10, the first driving component 321 is connected to the side of the first housing 326 towards the rear side of the housing 10. If the air deflector body 31 moves from the closed position towards the front side of the housing 10, the first driving component 321 is connected to the side of the first housing 326 towards the rear side of the housing 10.

[0055] In this embodiment, the second driving component 324 further includes at least one first driving gear 328 and at least one second driving gear 329. The number of the first driving gear 328 and the second driving gear 329 is the same as the number of the second motors 327 and they are arranged correspondingly. The first driving gear 328 is connected to the output shaft of the second motor 327 and rotates following the rotation of the output shaft. The second driving gear 329 meshes with the first driving gear 328 and is connected to the first rotating shaft 312, so as to rotate following the rotation when the first driving gear 328 rotates, thereby driving the air deflector body 31 to rotate. Here, the size of the first driving gear 328 is smaller than that of the second gear 322. The first driving gear 328 and the second driving gear 329 are both installed inside the first housing 326. See Figure 4 .

[0056] In this embodiment, the first driving component 321 includes a first motor, a gear 322 and a rack 323. The first motor is installed inside the housing 10. The gear 322 is connected to the first motor to rotate under the drive of the first motor. The rack 323 meshes with the gear 322, and one end of the rack 323 is connected to the first housing 326. The rack 323 is configured to move when the gear 322 rotates, so as to drive the air deflector body 31 to move. Here, the first driving component 321 further includes a second housing 325, and the first motor is located inside the second housing 325.

[0057] In this embodiment, one end of the rack 323 is connected to the first housing 326 of the second driving component 324. Since the second driving component 324 is connected to the air deflector body 31, when the rack 323 moves driven by the gear 322, it can drive the air deflector body 31 to move and will not affect the second driving component 324 to drive the air deflector body 31 to rotate, thus making the structure of the air deflector body 31 simpler.

[0058] In this embodiment, the air deflector body 31 moves towards the rear side of the housing 10, so the first driving component 321 is arranged at the rear side of the air supply channel 20. In other embodiments, if the air deflector body 31 moves towards the front side of the housing 10, the first driving component 321 is arranged at the front side of the air supply channel 20. That is to say, the installation position of the first driving component 321 needs to be determined according to the opening direction of the air deflector body 31. Generally, the first driving component 321 is installed at the rear side of the air supply channel 20.

[0059] In some embodiments, when the first driving component 321 is installed at the rear side of the air supply channel 20, the first driving component 321 drives the air deflector body 31 to move towards the rear side of the housing 10. After the movement or during the movement, the second driving component 324 drives the air deflector body 31 to rotate clockwise, so that the air deflector body 31 is switched from the horizontal state to the vertical state, that is, from the closed state to the open state. When the air deflector body 31 needs to be switched from the vertical state to the horizontal state, that is, from the open state to the closed state, the first driving component 321 drives the air deflector body 31 to move towards the front side of the housing 10. After the movement or during the movement, the second driving component 324 drives the air deflector body 31 to rotate counterclockwise, so that the air deflector body 31 is switched from the open state to the closed state.

[0060] In some embodiments, when the first driving component 321 is installed at the front side of the air supply channel 20, the first driving component 321 drives the air deflector body 31 to move towards the front side of the housing 10. After the movement or during the movement, the second driving component 324 drives the air deflector body 31 to rotate counterclockwise, so that the air deflector body 31 is switched from the horizontal state to the vertical state, that is, from the closed state to the open state. When the air deflector body 31 needs to be switched from the vertical state to the horizontal state, that is, from the open state to the closed state, the first driving component 321 drives the air deflector body 31 to move towards the rear side of the housing 10. After the movement or during the movement, the second driving component 324 drives the air deflector body 31 to rotate clockwise, so that the air deflector body 31 is switched from the open state to the closed state.

[0061] In this embodiment, the housing 10 has an accommodation space 11 located at the rear side of the air supply channel 20. The gear 322 is installed in the accommodation space 11 and partially protrudes from the accommodation space 11 to mesh with the rack 323. It can be understood that the second housing 325 is installed in the accommodation space 11, and the bottom of the gear 322 protrudes from the second housing 325 and the accommodation space 11 to mesh with the rack 323.

[0062] In this embodiment, the extension length of the rack 323 is determined according to the size of the air outlet and the width of the air deflector body 31, which is equivalent to being determined according to the moving stroke of the air deflector body 31. The longer the moving stroke of the air deflector body 31, the longer the extension length of the rack 323; the shorter the moving stroke of the air deflector body 31, the shorter the extension length of the rack 323. The design of the extension length of the rack 323 needs to ensure that the rotation axis of the air deflector body 31 can be moved to the bottom of the air duct rear wall 22, so as to ensure that the air volume of the air conditioner indoor unit 100 is the largest after the air deflector body 31 rotates.

[0063] In this embodiment, the air deflector body 31 moves from the closed state towards the rear side of the housing 10 to switch to the open state, and the rotation axis of the air deflector body 31 is located at the middle position of the air deflector body 31. In other embodiments, the rotation axis of the air deflector body 31 can also be designed according to specific circumstances. Additionally, the rotation axis of the air deflector body 31 can also be arranged at a position close to the front side of the housing 10 of the air deflector body 31. That is to say, the mounting arm 311 is arranged at a position close to the front side of the housing 10 of the air deflector body 31. Compared with the mounting arm 311 being arranged at the middle position of the air deflector body 31, when the air deflector body 31 is in the vertical state, the air guiding distance will be longer. When the mounting arm 311 is arranged at a position close to the rear side of the housing 10 of the air deflector body 31, compared with the mounting arm 311 being arranged at the middle position of the air deflector body 31, when the air deflector body 31 is in the vertical state, the air guiding distance will be shorter.

[0064] In this embodiment, the air deflector body 31 is arc-shaped, and the upper arc of the air deflector body 31 in the vertical state is approximately the same as the arc of the lower section of the air duct rear wall 22. When the air deflector body 31 moves and rotates towards the rear side of the housing 10 following the first driving component 321, the lower end of the air deflector body 31 bends towards the rear side of the housing 10. In some other embodiments, when the air deflector body 31 moves and rotates towards the front side of the housing 10 following the first driving component 321, the lower end of the air deflector body 31 bends towards the front side of the housing 10. In other embodiments, the air deflector body 31 can also be set to be flat, which can be specifically designed according to actual requirements. In this embodiment, the housing 10 has a bottom wall 12 located at the rear lower part of the air supply channel 20, and the rack 323 extends in the extending direction from the air outlet towards the bottom wall 12, so that the rack 323 can move along the bottom wall 12. Here, the shape of the rack 323 is consistent with the shape of the bottom wall 12. The rack 323 can drive the air deflector body 31 to move towards the rear side of the housing 10. In other embodiments, the housing 10 has a bottom wall located at the front lower part of the air supply channel 20, the rack 323 extends in the extending direction from the air outlet towards the bottom wall at the front lower part, and the rack 323 can drive the air deflector body 31 to move towards the front side of the housing 10.

[0065] In this embodiment, when the air deflector body 31 is in the closed state, a part of the rack 323 protrudes to the air outlet and abuts against the air deflector body 31. Refer to Figure 1 . It can be understood that when the air deflector body 31 is in the horizontal state, a part of the air deflector body 31 overlaps with a part of the rack 323. When the air deflector body 31 is converted from the horizontal state to the vertical state, the overlapping part of the air deflector body 31 rotates downward toward the lower part of the housing 10 and separates from the rack 323.

The first driving assembly 321 and the second driving assembly 324 are respectively connected to different mounting arms 311. If the first driving assembly 321 is connected to the first housing 326 of the second driving assembly 324, the air deflector body 31 does not need to be provided with an additional mounting arm 311, and only two mounting arms 311 connected to the second driving assembly 324 need to be provided. If the first driving assembly 321 is not connected to the first housing 326 of the second driving assembly 324, on the basis of providing two mounting arms 311 connected to the second driving assembly 324, the air deflector body 31 also needs to be provided with an additional mounting arm 311. The number of additional mounting arms 311 is the same as the number of the first driving assemblies 321. Each first driving assembly 321 is correspondingly connected to one mounting arm 311, and all the mounting arms 311 are on the same rotation axis of the air deflector body 31.

[0068] In some embodiments, the mounting arm 311 is connected to the first driving component 321 through the second rotating shaft 313, so that the air guide plate body 31 can move following the first driving component 321 and can rotate relative to the first driving component 321. Here, the structure of the mounting arm 311 connected to the first driving component 321 and the structure of the mounting arm 311 connected to the second driving component 324 can be set to be the same or different. In the case of being set to be the same, the mounting arm 311 has only one plate body, the first rotating shaft 312 passes through the plate body, the first housing 326 of the second driving component 324 is arranged on one side of the corresponding plate body and is connected to the corresponding plate body through the first rotating shaft 312. The rack 323 of the first driving component 321 is also arranged on one side of the corresponding plate body, the second rotating shaft 313 passes through the plate body, and the rack 323 of the first driving component 321 is connected to the corresponding plate body through the second rotating shaft 313. In the case of being set to be different, the mounting arm 311 connected to the second driving component 324 has only one plate body, the first rotating shaft 312 passes through the plate body, the first housing 326 of the second driving component 324 is arranged on one side of the corresponding plate body and is connected to the corresponding plate body through the first rotating shaft 312. The mounting arm 311 connected to the first driving component 321 is provided with two oppositely arranged plate bodies, the second rotating shaft 313 passes through the two plate bodies, the rack 323 of the first driving component 321 is located between the two plate bodies and is rotatably connected to the second rotating shaft 313.

[0069] In some embodiments, the air guide plate body 31 has four mounting arms 311, two of the mounting arms 311 are connected to the second driving component 324, and the other two mounting arms 311 are respectively connected to two first driving components 321.

[0070] In some embodiments, the two mounting arms 311 connected to the first driving component 321 are arranged between the two mounting arms 311 connected to the second driving component 324, see Figure 6 . The distance between the two mounting arms 311 connected to the first driving component 321 is specifically designed according to the design requirements. In other embodiments, the two mounting arms 311 connected to the first driving component 321 can also be respectively arranged outside the two mounting arms 311 connected to the second driving component 324, that is to say, the two mounting arms 311 connected to the first driving component 321 are closer to the end of the air guide plate body 31 than the two mounting arms 311 connected to the second driving component 324, and can be specifically designed according to the design requirements.
