[0044] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0045] Reference is made below to Figures 1 - 12 describe the air conditioner 100 according to an embodiment of the present invention. The air conditioner 100 may be a floor-standing air conditioner.

[0046] As Figures 1 - 12 shown, the air conditioner 100 according to an embodiment of the present invention includes: a housing 1 and a rotary air guiding assembly 2. An air duct 11 is provided in the housing 1, and an air outlet 12 is further provided in the housing 1. The air outlet 12 is communicated with the air duct 11, and the air in the air conditioner 100 can be blown out from the air outlet 12. The rotary air guiding assembly 2 is provided in the housing 1. Preferably, the rotary air guiding assembly 2 is provided in the housing 1. The rotary air guiding assembly 2 includes a first air guiding plate 22 and an air guiding body 21. The air guiding body 21 rotates around the central axis of the air guiding body 21. An air guiding space 23 is defined by the air guiding body 21. The air guiding space 23 corresponds to at least a part of the structure of the air outlet 12. A first air guiding plate 22 is provided in the air guiding space 23. After being separated by the first air guiding plate 22, the air guiding space 23 forms a plurality of air guiding openings 24.

[0047] Among them, the housing 1 may be extended and provided in the height direction of the air conditioner 100. It should be noted that the height direction of the air conditioner 100 may refer to Figure 1 the up-and-down direction in. The housing 1 may be composed of a front housing 15, an intermediate housing 16, a rear housing 17, and a top housing 18. The intermediate housing 16 may be clamped between the front housing 15 and the rear housing 17, and the front housing 15 and the rear housing 17 are spaced apart. The front housing 15 may include an upper front housing and a lower front housing. In the height direction of the air conditioner 100, the upper front housing may be provided above the lower front housing. The air outlet 12 may be provided on the front housing 15, and the air outlet 12 may be provided near the upper end of the air conditioner 100. A blower 4 may be provided in the housing 1. The blower 4 may be provided near the lower end of the housing 1, and the blower 4 may be communicated with the air duct 11.

[0048] An air inlet 14 of the housing 1 may be provided on the side wall of the housing 1. As Figure 1 shown, the side wall of the housing 1 may refer to Figure 1On the left and right side walls of the middle casing 1, preferably, the side walls of the front casing 15 may be provided with a casing air inlet 14. The casing air inlet 14 may be an air intake grille, and the air intake grille may be arranged to extend in the height direction of the air conditioner 100. The casing air inlet 14 can improve the air intake efficiency of the air conditioner 100. The casing air inlet 14 can be communicated with the air inlet of the air supply member 4. The air supply member 4 can suck air through the casing air inlet 14 and then send the compressed air into the air duct 11. Specifically, an air outlet interface may be provided at the upper end of the air supply member 4, and an air inlet interface may be provided at the lower end of the air duct 11. The air outlet interface can cooperate with the air inlet interface. After the air flow is compressed in the air supply member 4, it can be discharged into the air duct through the air inlet interface. The air flow in the air duct 11 can be blown out from the air outlet 12, and the air outlet can face the user. For example, Figure 1 as shown, the air can be blown out from the air outlet 12 towards the front side of the air conditioner 100.

[0049] Moreover, during the process of the air flow in the air duct 11 flowing towards the air outlet 12, the air flow can pass through the rotary air guiding assembly 2. The air flow can change its direction within the air guiding opening 24 defined by the air guiding body 21. Specifically, an included angle is provided between the central axis of the air guiding body 21 and the air guiding direction of the first air guiding plate 22. That is to say, the air guiding direction of the first air guiding plate 22 is not parallel to the central axis of the air guiding body 21. By providing an included angle between the central axis of the air guiding body 21 and the air guiding direction of the first air guiding plate 22, when the air flow blows over the surface of the first air guiding plate 22, the first air guiding plate 22 can make the blowing direction deviate from the central axis of the air guiding body 21, and the air can be blown out from different air guiding openings 24. The air guiding body 21 can control the included angle between the first air guiding plate 22 and the central axis of the air guiding body 21 so that the air guiding direction of the first air guiding plate 22 is adjustable. For example, when the first air guiding plate 22 guides the air to be blown out towards the left or right side close to the rotary air guiding assembly 2, the air outlet direction of the air outlet 12 can deflect towards the left or right side of the air outlet 12. The rotary air guiding assembly 2 can increase the air volume on the left or right side of the air outlet 12, and can also increase the adjustment angle of the air blowing direction of the air conditioner 100 to the left or right, thereby improving the experience of users on the left and right sides of the air conditioner 100.

[0050] Furthermore, when the first air guiding plate 22 guides the air to be blown out towards the lower side close to the rotary air guiding assembly 2, the air outlet direction of the air outlet 12 can deflect towards the lower side of the air outlet 12. The rotary air guiding assembly 2 can increase the adjustment angle of the air blowing direction of the air conditioner 100 downwards. When the air conditioner 100 blows out warm air, the rotary air guiding assembly 2 can make the air conditioner 100 blow air towards the ground, and the warm air can flow close to the ground, and the air conditioner 100 can provide a more comfortable experience for users in the heating mode.

[0051] Furthermore, when the first air deflector 22 guides the air to blow out towards the upper side close to the rotary air deflector assembly 2, the air outlet direction of the air outlet 12 can deflect upward towards the upper side of the air outlet 12. The rotary air deflector assembly 2 can increase the adjustment angle of the air blowing direction of the air conditioner 100 upward. When the air conditioner 100 blows cold air, the rotary air deflector assembly 2 can prevent the cold air from directly blowing on the user, and the air conditioner 100 can provide a more comfortable experience for the user in the cooling mode.

[0052] Thus, by arranging the rotary air deflector assembly 2 in the housing 1, compared with the prior art, the rotary air deflector assembly 2 can increase the air outlet angle of the air conditioner 100, improve the air blowing range of the air conditioner 100, and the air conditioner 100 can enable users at different positions to obtain a good air blowing experience, thereby improving the product quality of the air conditioner 100 and reducing user complaints.

[0053] In some embodiments of the present invention, such as Figure 2 、 Figure 4 、 Figure 5 、 Figures 7 - 11 shown, the rotary air deflector assembly 2 may further include: a transmission wheel 26 and a driving member 25. A transmission wheel 26 may be connected between the air deflector body 21 and the driving member 25, and the driving member 25 may be in transmission connection with the transmission wheel 26. The driving member 25 can drive the air deflector body 21 to rotate by driving the transmission wheel 26. Among them, in some specific embodiments of the present invention, the driving member 25 may be a motor, and the transmission wheel 26 may be provided with a mounting hole. The axis of the mounting hole is on the same axis as the axis of the transmission wheel 26. The transmission wheel 26 can be sleeved on the motor shaft of the motor through the mounting hole. When the motor shaft rotates, the driving member 25 can drive the transmission wheel 26 to rotate coaxially.

[0054] Moreover, the transmission wheel 26 may be arranged at the circumferential edge of the air deflector body 21, that is to say, the driving member 25 may be arranged at the circumferential edge of the air deflector body 21. Such an arrangement can prevent the transmission wheel 26 and the driving member 25 from obstructing the air flow in the air guiding space 23. When the driving member 25 drives the transmission wheel 26 to rotate, through the cooperation of the air deflector body 21 and the transmission wheel 26, the transmission wheel 26 can drive the air deflector body 21 to rotate, and the air guiding direction of the first air deflector 22 can change with the rotation of the air deflector body 21 to achieve the technical effect of guiding the air in different directions by the rotary air deflector assembly 2. Preferably, the driving member 25 may be a stepper motor. The stepper motor has high position accuracy and good motion repeatability. When the stepper motor drives the air deflector body 21 to rotate, the rotation angle of the air deflector body 21 is more accurate, that is to say, the air guiding direction of the rotary air deflector assembly 2 is more accurate, so that the air supply direction of the air conditioner 100 can be more suitable, and further the user's satisfaction with the air conditioner 100 can be higher.

[0055] In some embodiments of the present invention, such as Figure 2 、Figure 4 , Figure 5 , Figures 7 - 11 As shown, the first engaging tooth 27 can be arranged on the circumferential side wall of the transmission wheel 26, the second engaging tooth 28 can be arranged on the outer surface of the circumferential side wall of the air guiding body 21, and the second engaging tooth 28 can be meshed and connected with the first engaging tooth 27. Among them, the tooth surface of the first engaging tooth 27 is adapted to abut against the tooth surface of the second engaging tooth 28. When the driving member 25 drives the transmission wheel 26 to rotate, the first engaging tooth 27 can push the second engaging tooth 28 to move relative to the first engaging tooth 27, so that the air guiding body 21 rotates. By controlling the rotation direction of the transmission wheel 26, the blowing direction of the air conditioner 100 can be adjusted within a certain range, thereby improving the blowing range of the air conditioner 100.

[0056] It should be noted that the transmission wheel 26 can also be provided with weight reduction holes and reinforcing ribs. The weight reduction holes can be provided in multiple numbers, and the multiple weight reduction holes can reduce the weight of the transmission wheel 26. The reinforcing ribs can be provided in multiple numbers, and the multiple reinforcing ribs can improve the strength of the transmission wheel 26, thereby avoiding bending and breaking of the transmission wheel 26, and further improving the working stability of the transmission wheel 26.

[0057] In some embodiments of the present invention, as Figure 2 , Figure 4 , Figure 5 , Figures 7 - 11 shown, the rotary air guiding assembly 2 can further include: a second cover body 210 and a first cover body 29. A air guiding body 21 can be arranged between the first cover body 29 and the second cover body 210. The air guiding body 21 can rotate relative to the first cover body 29, and at the same time, the air guiding body 21 can also rotate relative to the second cover body 210. Among them, in the front-rear direction of the air conditioner 100, the first cover body 29 and the second cover body 210 can be respectively arranged on the front side and the rear side of the air guiding body 21, and the air guiding body 21 can be clamped between the first cover body 29 and the second cover body 210. Through the cooperation of the first cover body 29, the second cover body 210 and the air guiding body 21, the first cover body 29 and the second cover body 210 can fix the position of the rotary air guiding assembly 2 in the casing 1 and also prevent the rotary air guiding assembly 2 from interfering with the casing 1. The air guiding body 21 can rotate relative to the first cover body 29, and the air guiding body 21 can also rotate relative to the second cover body 210. The positions of the first cover body 29 and the second cover body 210 are fixed. The air guiding body 21 can drive the first air guiding plate 22 to rotate. As the first air guiding plate 22 rotates, the air guiding direction of the first air guiding plate 22 can be changed, that is, the first air guiding plate 22 can guide air above the air outlet 12, below the air outlet 12, to the left of the air outlet 12 or to the right of the air outlet 12, thereby improving the blowing range of the air conditioner 100.

[0058] In some embodiments of the present invention, asFigure 2 , Figure 4 , Figure 5 , Figures 7 - 11 As shown in Figures 7 - 11 , the air guiding body 21 may have a first surface 222, the first surface 222 may be opposite to the first cover body 29, the air guiding body 21 may have a second surface 223, the second surface 223 may be opposite to the second cover body 210, a limiting post 211 may be provided on the second surface 223 and / or the first surface 222, a limiting groove 212 may be provided on the second cover body 210 and / or the first cover body 29, the limiting groove 212 may be an annular structure, and the free end of the limiting post 211 may be installed in the limiting groove 212. Among them, as Figure 8 shown in Figure 8 , when the first cover body 29 is arranged on the front side of the air guiding body 21, the first surface 222 of the air guiding body 21 may refer to the front end outer surface of the air guiding body 21, and when the second cover body 210 is arranged on the rear side of the air guiding body 21, the second surface 223 of the air guiding body 21 may refer to the rear end outer surface of the air guiding body 21.

[0059] Moreover, the limiting post 211 may be provided on the second surface 223 and / or the first surface 222, that is to say, the limiting post 211 may be provided on the first surface 222, the limiting post 211 may also be provided on the second surface 223, the limiting post 211 may also be provided on both the first surface 222 and the second surface 223 at the same time. Preferably, the limiting post 211 may be provided on both the first surface 222 and the second surface 223 at the same time. The limiting post 211 may extend in the front-rear direction of the rotary air guiding assembly 2, and the front-rear direction of the rotary air guiding assembly 2 may refer to Figure 8 the front-rear direction in Figure 8 . The limiting post 211 may extend into the limiting groove 212, the limiting post 211 is adapted to abut against the bottom wall and / or the side wall of the limiting groove 212, and the limiting post 211 may define the spacing distance between the air guiding body 21 and the first cover body 29, and between the air guiding body 21 and the second cover body 210. In addition, the limiting groove 212 may also play a guiding role for the air guiding body 21. Specifically, during the rotation of the air guiding body 21, the limiting post 211 may move along the limiting groove 212, and the limiting groove 212 may prevent the movement track of the air guiding body 21 from deviating, so that the movement of the air guiding body 21 can be smoother.

[0060] Meanwhile, when the limiting post 211 is provided on the first surface 222, the friction force when the air guiding body 21 rotates relative to the first cover body 29 can be reduced by the cooperation of the limiting post 211 and the limiting groove 212. When the limiting post 211 is provided on the second surface 223, the friction force when the air guiding body 21 rotates relative to the second cover body 210 can be reduced by the cooperation of the limiting post 211 and the limiting groove 212, so that the noise generated when the air guiding body 21 rotates can be reduced, and the working stability of the rotary air guiding assembly 2 can also be improved.

[0061] In some embodiments of the present invention, as Figure 2 , Figure 4 , Figure 5 , Figures 7 - 11 shown, a plurality of limiting posts 211 may be provided. In the circumferential direction of the air guiding body 21, the plurality of limiting posts 211 may be spaced apart. Among them, a part of the plurality of limiting posts 211 may be provided on the first surface 222, and another part of the plurality of limiting posts 211 may be provided on the second surface 223. The plurality of limiting posts 211 provided on the first surface 222 may be spaced apart in the circumferential direction of the first surface 222, and the plurality of limiting posts 211 provided on the first surface 222 may all cooperate with the limiting grooves 212 on the first cover body 29, which can reduce the frictional force between the first cover body 29 and the air guiding body 21. The plurality of limiting posts 211 provided on the second surface 223 may be spaced apart in the circumferential direction of the second surface 223, and the plurality of limiting posts 211 provided on the second surface 223 may all cooperate with the limiting grooves 212 on the second cover body 210, which can reduce the frictional force between the second cover body 210 and the air guiding body 21. By providing a plurality of limiting posts 211, the noise generated when the air guiding body 21 rotates can be further reduced, and the working stability of the rotary air guiding assembly 2 can also be improved, thereby improving the use comfort of the air conditioner 100.

[0062] In some embodiments of the present invention, as Figures 7 - 11As shown, the second surface 223 and / or the first surface 222 may be provided with a rolling shaft 213. The rolling shaft 213 may rotate relative to the air guiding body 21, and at least part of the structure of the rolling shaft 213 may be installed in the limiting groove 212. Among them, the rolling shaft 213 may be provided on the first surface 222, the rolling shaft 213 may also be provided on the second surface 223, and the rolling shaft 213 may also be provided on the first surface 222 and the second surface 223. Preferably, the rolling shaft 213 may be provided on the second surface 223 or the first surface 222. It should be noted that a plurality of first air guiding plates 22 may be provided, and the plurality of first air guiding plates 22 may be arranged in parallel and spaced apart. The rolling shaft 213 may be a columnar plastic bushing, but the present invention is not limited thereto. For example, the rolling shaft 213 may also be provided as a bearing. The circumferential outer wall of the rolling shaft 213 may abut against the air guiding body 21. When the air guiding body 21 rotates, the air guiding body 21 may drive the rolling shaft 213 to rotate. The circumferential outer wall of the rolling shaft 213 may abut against the groove wall of the limiting groove 212, and the rolling shaft 213 may move along the limiting groove 212. By providing the rolling shaft 213 between the limiting groove 212 and the air guiding body 21, the frictional force between the rolling shaft 213 and the first cover body 29 and between the rolling shaft 213 and the second cover body 210 may be rolling frictional force, so that the frictional force between the rolling shaft 213 and the first cover body 29 and between the rolling shaft 213 and the second cover body 210 may be lower, and thus the jamming of the air guiding body 21 during rotation may be avoided.

[0063] In some embodiments of the present invention, as Figure 8 shown, the central axis of the air guiding body 21 may be perpendicularly arranged to the rotation axis of the rolling shaft 213. Among them, the rotation axis of the rolling shaft 213 may extend in the radial direction of the air guiding body 21. The rotation axis of the rolling shaft 213 may intersect with the central axis of the air guiding body 21, and the central axis of the air guiding body 21 may be perpendicularly arranged to the rotation axis of the rolling shaft 213. It can be understood that at this time, the side wall of the rolling shaft 213 may abut against the bottom wall of the limiting groove 212, and the side wall of the rolling shaft 213 may also abut against the first cover body 29 and / or the second cover body 210, so as to play a role in reducing the frictional force between the air guiding body 21 and the first cover body 29 and between the air guiding body 21 and the second cover body 210.

[0064] In some embodiments of the present invention, as Figure 9As shown, the central axis of the air guide body 21 can be arranged parallel to the rotation axis of the rolling shaft 213. Among them, the rotation axis of the rolling shaft 213 can be non-intersecting with the central axis of the air guide body 21, and the central axis of the air guide body 21 can be arranged parallel to the rotation axis of the rolling shaft 213. The side wall of the rolling shaft 213 can be abutted against the side wall of the limiting groove 212, and the side wall of the rolling shaft 213 can also be abutted against the bottom wall of the limiting groove 212, so as to reduce the frictional force between the air guide body 21 and the first cover body 29 and between the air guide body 21 and the second cover body 210. The above two embodiments can both enable the rolling shaft 213 to reduce the frictional force among the first cover body 29, the air guide body 21 and the second cover body 210, and can avoid jamming when the air guide body 21 rotates.

[0065] In some embodiments of the present invention, as Figures 7 - 11 shown, a plurality of rolling shafts 213 can be provided. In the circumferential direction of the air guide body 21, the plurality of rolling shafts 213 can be arranged at intervals. Preferably, four rolling shafts 213 can be provided on the air guide body 21, and the four rolling shafts 213 can be evenly spaced in the circumferential direction of the air guide body 21. Such an arrangement can improve the balance when the air guide body 21 rotates, and can also reduce the wear of the first meshing teeth 27 and the second meshing teeth 28 caused by the uneven weight of the air guide body 21. The rotation axes of the four rolling shafts 213 can all extend in the radial direction of the air guide body 21, and the rotation axes of the four rolling shafts 213 can also be parallel to the central axis of the air guide body 21.

[0066] In some embodiments of the present invention, as Figures 7 - 11 shown, the installation groove 226 can be provided on the second surface 223 and / or the first surface 222. The limiting post 211 can be provided in the installation groove 226, and the free end of the limiting post 211 can extend out from the open end of the installation groove 226. The free end of the limiting post 211 can be installed in the limiting groove 212. Preferably, the installation groove 226 can be provided on both the second surface 223 and the first surface 222 at the same time. By providing the installation groove 226 on the second surface 223 and the first surface 222, the installation groove 226 can reduce the weight of the air guide body 21, and it is easier for the driving member 25 to drive the air guide body 21 to rotate through the transmission wheel 26. The installation groove 226 can also improve the strength of the air guide body 21 and can avoid bending and breaking of the air guide body 21.

[0067] Moreover, in the axial direction of the air guiding body 21, the installation groove 226 can extend from the outside of the air guiding body 21 towards the inside of the air guiding body 21. The limiting post 211 can be arranged on the bottom wall of the installation groove 226, and the limiting post 211 can extend in the axial direction of the air guiding body 21. A part of the structure of the limiting post 211 can be arranged in the installation groove 226, and another part of the structure of the limiting post 211 can be set as the free end of the limiting post 211. The free end of the limiting post 211 can be arranged outside the installation groove 226, and the free end of the limiting post 211 can be used to abut against the limiting groove 212. The limiting post 211 can reduce the frictional force between the second cover body 210 and the air guiding body 21.

[0068] Furthermore, as Figures 7 - 11 shown, a plurality of installation grooves 226 can be provided, and the plurality of installation grooves 226 are all arranged to extend circumferentially on the air guiding body 21. At least two adjacent installation grooves 226 are provided with a rolling shaft 213, and the rolling shaft 213 can extend into the limiting groove 212. Among them, the plurality of installation grooves 226 are all configured as arc-shaped structures. When the air guiding body 21 is provided with four rolling shafts 213, both the first surface 222 and the second surface 223 can be provided with four installation grooves 226, and the four installation grooves 226 on the first surface 222 and the four installation grooves 226 on the second surface 223 can be arranged in one-to-one correspondence. An installation gap can be defined between any one installation groove 226 and the adjacent installation groove 226 on the same surface, and the rolling shaft 213 can be installed in the installation gap. An installation post is arranged in the installation gap, and the rolling shaft 213 can be installed on the installation post. The rolling shaft 213 can rotate around the installation post, and the installation post can prevent the rolling shaft 213 in the installation gap from falling off, thereby further improving the working stability of the rotary air guiding assembly 2. The rolling shaft 213 extending into the limiting groove 212 can reduce the frictional force between the first cover body 29, the air guiding body 21 and the second cover body 210, and can avoid jamming when the air guiding body 21 rotates.

[0069] In some embodiments of the present invention, as Figures 7 - 11As shown, the first mounting ear 214 can be arranged on the first cover body 29, the second mounting ear 215 can be arranged on the second cover body 210. The first mounting ear 214 can be provided with a first mounting hole 216, and the second mounting ear 215 can be provided with a second mounting hole 217. The second mounting hole 217 can be arranged corresponding to the first mounting hole 216. Among them, the first mounting ear 214 can be connected to the circumferential edge of the first cover body 29, and the second mounting ear 215 can be connected to the circumferential edge of the second cover body 210. When the driving member 25 and the transmission wheel 26 are arranged close to the upper end of the air guiding body 21, three first mounting ears 214 can be arranged on the first cover body 29, and the three first mounting ears 214 can be respectively arranged close to the left end, the right end and the lower end of the first cover body 29. That is to say, three second mounting ears 215 can be arranged on the second cover body 210, and the three second mounting ears 215 can be respectively arranged close to the left end, the right end and the lower end of the second cover body 210. Through the cooperation and connection of the three first mounting ears 214 and the three second mounting ears 215, the fastener can pass through the first mounting hole 216 and the second mounting hole 217 in sequence to install the air guiding body 21 between the first cover body 29 and the second cover body 210.

[0070] In some specific embodiments of the present invention, such as Figure 8 and Figure 9 As shown, a part of the structure of the second mounting ear 215 can be turned over towards the direction close to the first mounting ear 214. The part of the structure of the second mounting ear 215 that is turned over towards the direction close to the first mounting ear 214 can be abutted against the first mounting ear 214, and a fourth mounting hole 228 can be arranged on the part of the structure of the second mounting ear 215 that is turned over towards the direction close to the first mounting ear 214. A third mounting hole 227 can also be arranged on the first mounting ear 214, and the third mounting hole 227 can be arranged corresponding to the fourth mounting hole 228. A screw or a bolt can pass through the third mounting hole 227 and the fourth mounting hole 228 in sequence to fix the rotary air guiding assembly 2 on the casing 1.

[0071] Furthermore, such as Figures 7 - 11As shown, a first positioning portion 218 may be further provided on the first mounting ear 214, and a second positioning portion 219 may be further provided on the second mounting ear 215. The second positioning portion 219 may be in positioning cooperation with the first positioning portion 218. Among them, the first positioning portion 218 may be provided between the first mounting hole 216 and the first cover body 29, and the second positioning portion 219 may be provided between the second mounting hole 217 and the second cover body 210. During the process of assembling the rotary air guiding assembly 2 to the casing 1, the air guiding body 21 may be first installed between the first cover body 29 and the second cover body 210 through the cooperation and positioning of the first positioning portion 218 and the second positioning portion 219, and then the first mounting ear 214 and / or the second mounting ear 215 of the rotary air guiding assembly 2 may be installed on the casing 1. By the cooperation and connection of the first positioning portion 218 and the second positioning portion 219, the positions of the first mounting hole 216 and the second mounting hole 217 can be aligned, so that it is convenient for the fastener to pass through the first mounting hole 216 and the second mounting hole 217, and it can also be avoided that the central axes of the first cover body 29 and the second cover body 210 are not on the same straight line, thereby further improving the assembly accuracy of the rotary air guiding assembly 2.

[0072] In some embodiments of the present invention, as Figures 7 - 11 shown, the second positioning portion 219 may be set as one of a positioning hole and a positioning post, and the first positioning portion 218 may be set as the other of the positioning hole and the positioning post. Preferably, the second positioning portion 219 may be set as a positioning hole, and the first positioning portion 218 may be set as a positioning post. The positioning post may extend in the axial direction of the rotary air guiding assembly 2, and the positioning post may extend into the positioning hole for positioning with the positioning hole. The inner wall of the positioning hole may abut against the positioning post. After the second positioning portion 219 and the first positioning portion 218 are matched, the positions of the first cover body 29 and the second cover body 210 can be limited, thereby improving the assembly accuracy of the rotary air guiding assembly 2 and reducing the installation error between the first cover body 29 and the second cover body 210.

[0073] In some embodiments of the present invention, as Figure 2 、 Figure 4 、 Figure 5 、 Figures 7 - 11As shown, the third cover 220 can be disposed on the first cover 29, the fourth cover 221 can be disposed on the second cover 210, the fourth cover 221 can be connected to the third cover 220, and the fourth cover 221 and the third cover 220 can jointly define an installation space. A driving member 25 and a transmission wheel 26 can be disposed in the installation space. Among them, the third cover 220 can be connected to the circumferential edge of the first cover 29, and the fourth cover 221 can be connected to the circumferential edge of the second cover 210. When the driving member 25 and the transmission wheel 26 are disposed near the upper end of the rotary air guiding assembly 2, the third cover 220 can be disposed near the upper end of the first cover 29, and the fourth cover 221 can be disposed near the upper end of the second cover 210. One of the third cover 220 and the fourth cover 221 can be provided with a buckle, and the other of the third cover 220 and the fourth cover 221 can be provided with a claw. For example, as Figure 8 shown, the third cover 220 can be provided with buckles. A plurality of buckles can be spaced apart from each other on the circumferential edge of the third cover 220. The fourth cover 221 can be provided with claws. A plurality of claws can be spaced apart from each other on the circumferential edge of the fourth cover 221. Through the cooperation of the buckles and the claws, the third cover 220 and the fourth cover 221 can be connected together.

[0074] Moreover, the third cover 220 can include a driving member assembly groove 224 and a driving member positioning groove 225. The driving member assembly groove 224 can communicate with the driving member positioning groove 225. A partial structure of the driving member 25 can be disposed in the driving member assembly groove 224 and the driving member positioning groove 225. The driving member positioning groove 225 can position the driving member 25 and can prevent the driving member 25 from rotating during operation. Further, in order to prevent the driving member 25 from rotating during operation, the driving member 25 can be installed on the third cover 220 through a fastener, so that the position of the driving member 25 on the rotary air guiding assembly 2 is fixed. When the driving member 25 is a stepping motor, both the driving member 25 and the transmission wheel 26 can be disposed in the installation space. The installation space can prevent the driving member 25 and the transmission wheel 26 from falling out of the rotary air guiding assembly 2, and the installation space can improve the working stability of the rotary air guiding assembly 2. A motor shaft hole can be provided on the fourth cover 221. After the motor shaft of the stepping motor passes through the transmission wheel 26, it can extend into the motor shaft hole. The motor shaft hole can make the driving member 25 operate more stably, thereby reducing the noise generated during the operation of the rotary air guiding assembly 2 and making the rotary air guiding assembly 2 operate more smoothly.

[0075] In some embodiments of the present invention, as Figures 1 - 6 shown, the second air guiding plate 13 can be disposed on the air outlet 12, and the second air guiding plate 13 is adapted to swing around the transverse axis of the air outlet 12. Among them, the transverse axis of the air outlet 12 is in Figure 1It extends in the left - right direction. The second air deflector 13 can be provided in multiple numbers. The multiple second air deflectors 13 can be spaced apart in the height direction of the air conditioner 100, and the multiple second air deflectors 13 can all extend in the width direction of the air conditioner 100. The width direction of the air conditioner 100 refers to Figure 1 the left - right direction in the middle. The transverse axes of the air outlets 12 can be provided in multiple numbers corresponding to the second air deflectors 13. The transverse axes of the multiple air outlets 12 can all extend in the width direction of the air conditioner 100. The second air deflector 13 is adapted to swing in the up - down direction of the air conditioner 100 around the transverse axis of the air outlet 12.

[0076] Moreover, when the second air deflector 13 swings upward around the transverse axis of the air outlet 12, after the air in the air duct 11 is deflected by the second air deflector 13, the second air deflector 13 can adjust the flow direction of the air current. When the air blows out from the air outlet 12, the air conditioner 100 can blow air upward. When the second air deflector 13 swings downward around the transverse axis of the air outlet 12, after the air in the air duct 11 is deflected by the second air deflector 13, the second air deflector 13 can adjust the flow direction of the air current. When the air blows out from the air outlet 12, the air conditioner 100 can blow air downward. By the cooperation of the second air deflector 13 and the first air deflector 22, the air - guiding direction of the second air deflector 13 is superimposed on the air - guiding direction of the first air deflector 22, which can make the air - blowing adjustment angle of the air conditioner 100 larger, thereby increasing the air - blowing range of the air conditioner 100.

[0077] During the use of the air conditioner 100, when the air conditioner 100 operates in the heating mode, the rotary air - guiding assembly 2 can control the first air deflector 22 to guide air downward, and the second air deflector 13 can swing downward. The air current in the air duct 11 is deflected by the first air deflector 22 and the second air deflector 13 and then can be blown out toward the lower part of the air outlet 12. The hot air can flow close to the ground, and the air conditioner 100 can provide a more comfortable experience for users in the heating mode.

[0078] Furthermore, when the air conditioner 100 operates in the cooling mode, the rotary air - guiding assembly 2 can control the first air deflector 22 to guide air upward, and the second air deflector 13 can swing upward. The air current in the air duct 11 is deflected by the first air deflector 22 and the second air deflector 13 and then can be blown out toward the upper part of the air outlet 12. The air conditioner 100 will not directly blow cold air at the user, thereby further improving the comfort of using the air conditioner 100.

[0079] In some embodiments of the present invention, as Figure 2 、 Figures 4 - 6 shown, the air conditioner 100 may further include: a heating element 3. The air outlet 12 can be correspondingly arranged with the heating element 3. The heating element 3 can extend in the transverse direction of the air outlet 12. The transverse direction of the air outlet 12 can refer to Figure 1The left - right direction in it. Wherein, by arranging the heating element 3 in the air conditioner 100, when the heating element 3 is started and the air flow in the air duct 11 passes through the heating element 3, the heating element 3 can heat the air flow in the air duct 11, so that the air conditioner 100 can blow out warm air. The heating element 3 can be fixed on the evaporator 5 of the air conditioner 100. Specifically, the evaporator 5 can be inclined in the height direction of the air conditioner 100, the heating element 3 can be fixed on the surface of the evaporator 5 opposite to the air outlet 12, and multiple heating elements 3 can be arranged on the evaporator 5. The multiple heating elements 3 are spaced apart in the height direction of the evaporator 5. The height direction of the evaporator 5 can refer to Figure 1 The up - down direction in it. Refrigerant can be introduced into the evaporator 5. When the air flow in the air duct 11 passes through the evaporator 5, the refrigerant in the evaporator 5 can vaporize. During the vaporization process of the refrigerant, the refrigerant can absorb the heat in the air flow, so that the air conditioner 100 can blow out cold air. By fixing the heating element 3 on the evaporator 5 of the air conditioner 100, there is no influence between the evaporator 5 and the heating element 3 when the air conditioner 100 works in the warm - air mode or the cold - air mode.

[0080] By arranging the air outlet 12 corresponding to the heating element 3 and the heating element 3 extending in the lateral direction of the air outlet 12, it is beneficial to improve the temperature difference of the air blown out from the air outlet 12. It should be noted that the temperature difference of the air blown out from the air outlet 12 refers to the temperature difference of the air blown out between the upper end and the lower end of the air outlet 12. Compared with the prior art, the present invention can make the air flow pass through the heating element 3 smoothly, so that the temperature of the air flow is more uniform. When the air conditioner 100 sends warm air to the user, the user experience is better.

[0081] Furthermore, when the air conditioner 100 works in the warm - air mode, the heating element 3 can heat the air flow in the air duct 11. Since the heating element 3 and the air outlet 12 are spaced apart in the front - back direction of the air conditioner 100, during the process that the air flow flows from the heating element 3 to the air outlet 12 after heat exchange on the heating element 3, the heat in the air flow is likely to be dissipated to the external environment, resulting in a decrease in the temperature of the air blown out from the air outlet 12. In order to reduce the heat loss of the air flow in the air duct 11, a heat - insulating member can be arranged between the heating element 3 and the air outlet 12. The heat - insulating member can prevent the air flow in the air duct 11 from exchanging heat with the external environment, thereby increasing the temperature of the air blown out from the air outlet 12.

[0082] Moreover, when the air conditioner 100 operates in the cold air mode, since the evaporator 5 and the air outlet 12 are spaced apart in the front-rear direction of the air conditioner 100, after the air flow exchanges heat on the evaporator 5, during the process of the air flow flowing from the evaporator 5 to the air outlet 12, the air flow is likely to exchange heat with the external environment and then warm up. By providing the heat insulation member, the heat insulation member can prevent the air flow in the air duct 11 from exchanging heat with the external environment, thereby reducing the air outlet temperature of the air outlet 12, and further enabling the air conditioner 100 to more quickly reduce the indoor temperature.

[0083] In some embodiments of the present invention, the projection of the air guiding space 23 in the air outlet direction of the air conditioner 100 may be located within the projection range of the air outlet 12. Wherein, the air outlet direction of the air conditioner 100 may refer to Figure 1 the front direction in, a part of the projection of the air guiding space 23 may be located within the projection range of the air outlet 12, or the entire projection of the air guiding space 23 may be located within the projection range of the air outlet 12. In the air outlet direction of the air conditioner 100, a part of the air flow in the air duct 11 may flow out from the air guiding space 23 and blow towards the air outlet 12, and another part of the air flow in the air duct 11 may not flow out from the air guiding space 23 but directly blow out from the air outlet 12. The air flow blown out from the air guiding opening 24 and the air flow not blown out from the air guiding opening 24 may disturb each other, thereby making the air blown out by the air conditioner 100 softer, and further improving the use comfort of the air conditioner 100.

[0084] In some embodiments of the present invention, the air outlet grille may be provided at the air outlet 12, and the projection of the air guiding space 23 in the air outlet direction of the air conditioner 100 does not coincide with the projection of the air outlet grille. Wherein. By providing the air outlet grille at the air outlet 12, the air outlet grille can shield the air outlet 12, thereby preventing the user from directly looking at the components inside the cabinet 1, and further meeting the aesthetic requirements of the user for the air conditioner 100. The air outlet grille can also prevent dust from falling into the cabinet 1 and keep the interior of the air conditioner 100 clean.
