[0055] Reference Figures 1 to 7 This document shows a schematic diagram of an air supply structure for an air conditioner according to an embodiment of this application. The air supply structure is applied to a wall-mounted air conditioner and may specifically include: an air guide mechanism, an air sweeping mechanism, a gear transmission assembly, a lead screw and nut transmission assembly, and a drive mechanism.

[0056] The drive mechanism is connected to the gear transmission assembly, and the gear transmission assembly is connected to the air guide mechanism to drive the air guide mechanism to rotate in the first direction X.

[0057] The drive mechanism is connected to the lead screw and nut transmission assembly, which is connected to the air-sweeping mechanism to drive the air-sweeping mechanism to rotate in the second direction Y.

[0058] The first direction X intersects with the second direction Y.

[0059] In this embodiment, a drive mechanism can simultaneously drive the gear transmission assembly and the lead screw and nut transmission assembly, causing the gear transmission assembly to rotate the air guide mechanism and the lead screw and nut transmission assembly to rotate the air sweeping mechanism. This allows the air conditioner's air supply structure to deliver air in the intersecting first direction X and second direction Y. This avoids the need for multiple structures such as drive linkages, rotating disks, support rods, brackets, swing linkages, cranks, connecting shafts, and air sweeping rods to rotate the air guide and air sweeping mechanisms, simplifying the air supply structure of the air conditioner, reducing the number of parts, and facilitating the internal layout of the air conditioner. Furthermore, the gear transmission assembly can further improve the accuracy and reliability of the transmission to the air guide mechanism, and the lead screw and nut transmission assembly can further improve the accuracy and reliability of the transmission to the air sweeping mechanism.

[0060] For example, in this embodiment of the application, the first direction X can be a vertical direction, and the air guiding mechanism rotates in the first direction X, so that the air conditioner's air supply structure can supply air in the up and down direction. The second direction Y can be a horizontal direction, and the air sweeping mechanism rotates in the second direction Y, so that the air conditioner's air supply structure can supply air in the left and right direction. That is, the first direction X can be perpendicular to the second direction Y.

[0061] Furthermore, in the embodiments of this application, the angle between the first direction X and the second direction Y can also be 80° or 60°, etc., so that the air supply structure of the air conditioner can supply air in multiple directions and enrich the air supply effect. The specific value of the angle between the first direction X and the second direction Y is not limited in the embodiments of this application.

[0062] Optionally, in this embodiment, the driving mechanism includes a driver and a drive gear 110; the output end of the driver is connected to the drive gear 110, and the drive gear 110 meshes with the gear transmission assembly and the lead screw and nut transmission assembly respectively; the driver drives the drive gear 110 to rotate, thereby driving the gear transmission assembly and the lead screw and nut transmission assembly to rotate respectively, thereby driving the air guide mechanism to rotate in the first direction X, and driving the air sweeping mechanism to rotate in the second direction Y. Thus, by providing a stable and reliable power source through the driver, and by having the drive gear 110 mesh with the gear transmission assembly and the lead screw and nut transmission assembly respectively, the driving mechanism can simultaneously drive the gear transmission assembly and the lead screw and nut transmission assembly to rotate respectively. Therefore, the gear transmission assembly drives the air guide mechanism to rotate in the first direction X to deliver air, and the lead screw and nut transmission assembly drives the air sweeping mechanism to rotate in the second direction Y to deliver air.

[0063] For example, in the embodiments of this application, the driver can be a motor or electric motor, etc. The specific type of driver is not limited in the embodiments of this application.

[0064] In this embodiment, optionally, the gear transmission assembly includes a first gear 210 and a second gear 220; the first gear 210 meshes with a drive gear 110, the second gear 220 meshes with the first gear 210, and the air guide mechanism is connected to the second gear 220; the drive gear 110 drives the first gear 210 to rotate, the first gear 210 drives the second gear 220 to rotate, and the second gear 220 drives the air guide mechanism to rotate in a first direction X. Thus, the first gear 210 connects the gear transmission assembly to the drive mechanism, and the second gear 220 connects the gear transmission assembly to the air guide mechanism, enabling the drive mechanism to drive the air guide mechanism to rotate for air delivery. Furthermore, the transmission between the drive mechanism and the air guide mechanism is achieved through gear transmission, improving the driving accuracy and reliability of the drive mechanism's control over the air guide mechanism.

[0065] In some optional embodiments of this application, the first gear 210 includes an external gear 211 and an internal gear 212 coaxially arranged, with the diameter of the external gear 211 being larger than the diameter of the internal gear 212. The external gear 211 meshes with the drive gear 110, and the internal gear 212 meshes with the second gear 220. The drive gear 110 drives the external gear 211 to rotate, the external gear 211 drives the internal gear 212 to rotate, and the internal gear 212 drives the second gear 220 to rotate. In this way, the transmission of the first gear 210 can be achieved through the combination of the external gear 211 and the internal gear 212, which can reduce the speed transmitted by the drive gear 110, and the space occupied is small, which is beneficial to the structural layout of the air supply structure of the air conditioner.

[0066] Specifically, in this embodiment, the external gear 211 and the internal gear 212 are coaxially arranged and have the same angular velocity. The diameter of the external gear 211 is larger than the diameter of the internal gear 212, meaning that the number of teeth on the external gear 211 can be greater than the number of teeth on the internal gear 212. Furthermore, the external gear 211 and the internal gear 212 are staggered to avoid interference between the external gear 211 and the transmission between the internal gear 212 and the second gear 220.

[0067] Optionally, in this embodiment, the air conditioner's air supply structure further includes an output gear 230, which meshes with a second gear 220. An air guide plate 320 is connected to the output gear 230. Rotation of the second gear 220 drives the output gear 230 to rotate, and the output gear 230 drives the air guide mechanism to rotate in the first direction X. Thus, the transmission between the second gear 220 and the air guide mechanism is achieved through the output gear 230, resulting in a more reliable transmission effect. For example, the cross-sectional shape of the output gear 230 can be fan-shaped, so that while achieving a good transmission effect, the space occupied by the output gear 230 is reduced, and the layout of the output gear 230 is also convenient.

[0068] Optionally, in this embodiment, the air guiding mechanism includes an air guide plate shaft 310 and an air guide plate 320. The air guide plate shaft 310 is connected to an output gear 230, and the air guide plate 320 is connected to the air guide plate shaft 310. The output gear 230 rotates, causing the air guide plate shaft 310 to rotate, which in turn causes the air guide plate 320 to rotate in the first direction X. Thus, the output gear 230 transmits power to the air guide plate shaft 310, which reciprocates around its axis, causing the air guide plate 320 to rotate in the first direction X to deliver air. Specifically, the air guide plate shaft 310 can be a cross-shaped structure to facilitate connection to the casing of the indoor unit of a wall-mounted air conditioner and to the air guide plate 320. Alternatively, the air guide plate shaft 310 can be T-shaped, etc. The specific shape of the air guide plate shaft 310 is not limited in this embodiment.

[0069] Optionally, in this embodiment, the lead screw and nut transmission assembly includes a third gear 410, a gear nut 420, and a lead screw 430. The third gear 410 meshes with the drive gear 110, the outer surface of the gear nut 420 meshes with the third gear 410, and the lead screw 430 passes through the gear nut 420 and meshes with its inner surface. The air-sweeping mechanism is connected to the lead screw 430. The drive gear 110 drives the third gear 410 to rotate, the third gear 410 drives the gear nut 420 to rotate, the gear nut 420 drives the lead screw 430 to move, and the lead screw 430 drives the air-sweeping mechanism to rotate in the second direction Y. Thus, the third gear 410 connects the lead screw and nut transmission assembly to the drive mechanism, and the gear nut 420 and the lead screw 430 change the direction of force transmission, converting rotational motion into translational motion, thereby causing the lead screw 430 to drive the air-sweeping mechanism to rotate in the second direction Y to deliver air.

[0070] In some optional embodiments of this application, the air supply structure of the air conditioner further includes a bushing 440, which is disposed on the outer periphery of the gear nut 420 and the lead screw 430. The bushing 440 has a limiting part 441 corresponding to the gear nut 420 to restrict the horizontal movement of the gear nut 420. The bushing 440 has a sliding groove 442 near the lead screw 430, and the lead screw 430 is slidably connected to the sliding groove 442 in the horizontal direction. Thus, the limiting part 441 restricts the translational movement of the gear nut 420, ensuring that the gear nut 420 only rotates, preventing it from rotating and disengaging from the third gear 410. Furthermore, the sliding groove 442 restricts the rotational movement of the lead screw 430, ensuring that the lead screw 430 only translates, preventing unnecessary wear caused by rotation.

[0071] Specifically, in this embodiment, the lead screw 430 is provided with a protruding guide block 431, which is slidably connected to the slide groove 442 in the horizontal direction. In this way, the guide block 431 guides the movement of the lead screw 430 in the horizontal direction, enabling it to perform translational movement. Furthermore, the guide block 431 can be engaged in the slide groove 442, which further limits the rotation of the lead screw 430 and prevents wear.

[0072] For example, in the embodiments of this application, the number of guide blocks 431 can be one or two, respectively disposed at both ends of the lead screw 430. The number of guide blocks 431 can also be three, disposed at intervals on the lead screw 430. The specific number and arrangement of guide blocks 431 in the embodiments of this application are not limited.

[0073] Optionally, in this embodiment, the air supply structure of the air conditioner further includes a connecting shaft 450 and a connecting rod 460; one end of the connecting shaft 450 is connected to one end of the lead screw 430, one end of the connecting rod 460 is connected to the other end of the connecting shaft 450, and the other end of the connecting rod 460 is movably connected to the swing mechanism; the lead screw 430 drives the connecting shaft 450 to move, the connecting shaft 450 drives the connecting rod 460 to move, and the connecting rod 460 drives the swing mechanism to rotate in the second direction Y. Thus, the reciprocating translational motion of the lead screw 430 in the horizontal direction can drive the connecting rod 460 to rotate through the connecting shaft 450, thereby causing the connecting rod 460 to drive the swing mechanism to rotate in the second direction Y.

[0074] Specifically, in this embodiment, a connecting ring 451 is provided at one end of the connecting shaft 450. The connecting ring 451 is sleeved on one end of the lead screw 430, and the axial direction of the connecting ring 451 coincides with the axial direction of the lead screw 430. That is, the axial direction of the connecting ring 451 is perpendicular to the axial direction of the other end of the connecting shaft 450. In this way, if the lead screw 430 rotates, it will only rotate relative to the connecting ring 451, avoiding the transmission of the rotation generated by the lead screw 430 to the connecting rod 460, which would cause damage to the connecting shaft 450 and the connecting rod 460.

[0075] Optionally, in this embodiment, the sweeping mechanism includes a sweeping connecting rod 510 and a sweeping plate 520 connected to the sweeping connecting rod 510. One end of the sweeping connecting rod 510 is movably connected to a connecting rod 460. The connecting rod 460 drives the sweeping connecting rod 510 to move, and the sweeping connecting rod 510 drives the sweeping plate 520 to rotate in the second direction Y. Specifically, the connecting rod 460 drives the sweeping connecting rod 510 to translate horizontally, so that the sweeping connecting rod 510 drives the sweeping plate 520 to rotate in the second direction Y to deliver air.

[0076] For example, in this embodiment of the application, there may be multiple air-sweeping plates 520. Multiple air-sweeping plates 520 are connected to the air-sweeping connecting rod 510 at intervals. The air-sweeping connecting rod 510 moves horizontally, causing the air-sweeping plates 520 to rotate in the second direction Y to deliver air.

[0077] Optionally, in this embodiment, the air supply structure of the air conditioner further includes a movable rod 530. One end of the movable rod 530 is movably connected to the swing link 510, and the other end of the movable rod 530 is used to connect to the housing to support the swing link 510. In this way, the movable rod 530 provides relatively stable support for the swing link 510, preventing the swing link 510 from being easily bent or damaged during movement.

[0078] In summary, the air supply structure of the air conditioner described in the embodiments of this application can include at least the following advantages:

[0079] In this embodiment, the air conditioner's air supply structure includes: an air guide mechanism, a sweeping mechanism, a gear transmission assembly, a lead screw and nut transmission assembly, and a drive mechanism. The drive mechanism is connected to the gear transmission assembly, which is connected to the air guide mechanism to drive the air guide mechanism to rotate in a first direction. The drive mechanism is also connected to the lead screw and nut transmission assembly, which is connected to the sweeping mechanism to drive the sweeping mechanism to rotate in a second direction. The first and second directions intersect. This allows the drive mechanism to simultaneously drive both the gear transmission assembly and the lead screw and nut transmission assembly, causing the gear transmission assembly to rotate the air guide mechanism and the lead screw and nut transmission assembly to rotate the sweeping mechanism, thus enabling the air conditioner's air supply structure to deliver air in the intersecting first and second directions. This avoids the need for multiple structures such as drive linkages, rotating disks, support rods, brackets, swing linkages, cranks, connecting shafts, and sweeping linkages to rotate the air guide and sweeping mechanisms, simplifying the air supply structure, reducing the number of parts, and facilitating the internal layout of the air conditioner. Furthermore, the gear transmission assembly can further improve the accuracy and reliability of the transmission to the air guide mechanism, and the screw and nut transmission assembly can further improve the accuracy and reliability of the transmission to the air sweeping mechanism.

[0081] Specifically, the indoor unit of the wall-mounted air conditioner is provided with an air outlet, and the air guide plate 320 and the air sweeping plate 520 of the air supply structure of the air conditioner are located at the air outlet.

[0083] In this embodiment, the indoor unit of the wall-mounted air conditioner includes the air supply structure, which comprises: an air guide mechanism, a sweeping mechanism, a gear transmission assembly, a lead screw and nut transmission assembly, and a drive mechanism. The drive mechanism is connected to the gear transmission assembly, which is connected to the air guide mechanism to drive the air guide mechanism to rotate in a first direction. The drive mechanism is also connected to the lead screw and nut transmission assembly, which is connected to the sweeping mechanism to drive the sweeping mechanism to rotate in a second direction. The first and second directions intersect. Thus, the drive mechanism can simultaneously drive the gear transmission assembly and the lead screw and nut transmission assembly, causing the gear transmission assembly to rotate the air guide mechanism and the lead screw and nut transmission assembly to rotate the sweeping mechanism, thereby enabling the air supply structure to deliver air in the intersecting first and second directions. This design avoids the need for multiple structures such as drive linkages, rotating discs, support rods, brackets, swing linkages, cranks, connecting shafts, and swing linkages to rotate the air guiding and swinging mechanisms. This simplifies the air supply structure of the air conditioner, reduces the number of parts, and facilitates the internal layout of the air conditioner. Furthermore, the gear transmission assembly further improves the accuracy and reliability of the transmission to the air guiding mechanism, and the screw-nut transmission assembly further improves the accuracy and reliability of the transmission to the swinging mechanism.

Thus, the drive mechanism can simultaneously drive the gear transmission assembly and the lead screw and nut transmission assembly, causing the gear transmission assembly to rotate the air guide mechanism and the lead screw and nut transmission assembly to rotate the sweeping mechanism, thereby enabling the air supply structure to supply air in the intersecting first and second directions. This design avoids the need for multiple structures such as drive linkages, rotating discs, support rods, brackets, swing linkages, cranks, connecting shafts, and swing linkages to rotate the air guiding and swinging mechanisms. This simplifies the air supply structure of the air conditioner, reduces the number of parts, and facilitates the internal layout of the air conditioner. Furthermore, the gear transmission assembly further improves the accuracy and reliability of the transmission to the air guiding mechanism, and the screw-nut transmission assembly further improves the accuracy and reliability of the transmission to the swinging mechanism.
