[0045] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein 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 by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0047] The air conditioner 100 according to the embodiments of the present invention will be described below with reference to the drawings.

[0048] According to an embodiment of the present utility model, the air conditioner 100, as Figures 1-3 shown, the air conditioner 100 includes: an air conditioner main body 10 and a lower air outlet control component 20. The air conditioner main body 10 has a main air duct 11 and a fresh air duct 12. The air conditioner main body 10 has a main air outlet 1a and a lower air outlet 1b. The main air outlet 1a is communicated with the main air duct 11, and the lower air outlet 1b is lower than the main air outlet 1a. The lower air outlet control component 20 is arranged on the air conditioner main body 10 and is used for controlling the communication state between the main air duct 11 and the lower air outlet 1b, and the communication state between the fresh air duct 12 and the lower air outlet 1b.

[0049] The air conditioner main body 10 has a main air duct 11 and a fresh air duct 12. The main air duct 11 conveys a heat exchange air flow to the room to adjust the room temperature. The fresh air duct 12 conveys fresh air to the room to improve the indoor air quality, replacing the stale air with fresh air.

[0050] The air conditioner main body 10 has a main air outlet 1a and a lower air outlet 1b. The lower air outlet 1b is arranged lower than the main air outlet 1a. The air conditioner 100 can not only convey the air flow from the main air outlet 1a, but also convey the air flow from the lower air outlet 1b, improving the air supply range of the air conditioner 100 in the vertical direction and enhancing the air supply effect.

[0051] Among them, the main air outlet 1a is communicated with the main air duct 11, and the lower air outlet 1b can be selectively communicated with the main air duct 11 and the fresh air duct 12. Thus, the air conditioner 100 can realize multi-mode air supply to meet the requirements of different scenarios.

[0052] Optionally, the control of the communication state between the main air duct 11 and the lower air outlet 1b by the lower air outlet control component 20 and the control of the communication state between the fresh air duct 12 and the lower air outlet 1b can be independently controlled. Exemplarily, two valves can be used to respectively control the opening and closing of the fresh air duct 12 and the main air duct 11 with the lower air outlet 1b. The lower air outlet 1b is independently opened and closed with the main air duct 11, and at the same time, the lower air outlet 1b is independently opened and closed with the fresh air duct 12. At this time, the lower air outlet 1b can be separately communicated with the main air duct 11, or the lower air outlet 1b can be separately communicated with the fresh air duct 12, or the lower air outlet 1b can be simultaneously communicated with the main air duct 11 and the fresh air duct 12.

[0053] Alternatively, the control of the communication state between the main air duct 11 and the lower air outlet 1b by the lower air outlet control component 20 and the control of the communication state between the fresh air duct 12 and the lower air outlet 1b can be interrelated control. Exemplarily, one valve can be used to control the communication between one of the main air duct 11 and the fresh air duct 12 and the lower air outlet 1b. When the lower air outlet 1b is communicated with the main air duct 11, the lower air outlet 1b is isolated from the fresh air duct 12; when the lower air outlet 1b is communicated with the fresh air duct 12, the lower air outlet 1b is isolated from the main air duct 11.

[0054] The connection state between the main control air duct 11 of the lower air outlet control component 20 and the lower air outlet 1b, and the selection of whether the connection state between the fresh air duct 12 and the lower air outlet 1b is independently controlled or correlated controlled can be selected according to actual needs.

[0055] Next, several air supply modes of the air conditioner 100 according to some embodiments of the present invention will be briefly described.

[0056] Exemplarily, for example, the lower air outlet 1b is only connected to the main air duct 11, and both the main air outlet 1a and the lower air outlet 1b convey the heat exchange air flow to the room. Compared with only supplying air through the main air outlet 1a, the heat exchange air flow conveyed downward by the air conditioner 100 can be increased. When supplying hot air, the hot air can be conveyed to the user's feet, warming the feet and improving the steady-state thermal comfort of the human body.

[0057] Exemplarily, also for example, the lower air outlet 1b is only connected to the fresh air duct 12, the main air duct 11 does not work, and the lower air outlet 1b conveys fresh air to the room, which can update the indoor air and add new air purification.

[0058] Exemplarily, again for example, the lower air outlet 1b is only connected to the fresh air duct 12, the lower air outlet 1b conveys fresh air to the room, and the main air outlet 1a conveys the heat exchange air flow to the room, which can improve the indoor air quality while adjusting the indoor temperature.

[0059] Exemplarily, furthermore, for example, while the lower air outlet 1b is connected to the fresh air duct 12, the lower air outlet 1b is also connected to the main air duct 11. The lower air outlet 1b conveys a mixed air flow of fresh air and heat exchange air flow to the room, and the main air outlet 1a conveys the heat exchange air flow to the room, which can improve the indoor air quality while adjusting the indoor temperature.

[0060] In the air conditioner 100 according to the embodiment of the present invention, by providing the lower air outlet 1b and the lower air outlet control component 20, the lower air outlet 1b can be switched to be connected to the main air duct 11 and the fresh air duct 12. The lower air outlet 1b can convey both the heat exchange air flow and the fresh air. The lower air outlet 1b cooperates with the main air outlet 1a to supply air. One lower air outlet 1b can meet the air supply requirements of both the main air duct 11 and the fresh air duct 12, without having to set corresponding air outlets in the air conditioner 100 for the respective air supply requirements of the main air duct 11 and the fresh air duct 12. Thus, the number of air outlets of the air conditioner 100 can be reduced, the structure of the air conditioner 100 can be simplified, and the manufacturing difficulty of the air conditioner 100 can be reduced.

[0061] In some embodiments of the present invention, the lower air outlet control component 20 can be switched between a first state and a second state. As Figure 3 shown, in the first state, the lower air outlet control component 20 blocks the connection between the lower air outlet 1b and the main air duct 11, and makes the lower air outlet 1b connected to the fresh air duct 12. As Figure 2As shown, in the second state, the lower air outlet control component 20 blocks the lower air outlet 1b from the fresh air duct 12 and connects the lower air outlet 1b to the main duct 11.

[0062] The lower air outlet control component 20 controls the connection state between the main duct 11 and the lower air outlet 1b, and the connection state between the fresh air duct 12 and the lower air outlet 1b is controlled in an interrelated manner. When the lower air outlet control component 20 connects the lower air outlet 1b to the main duct 11, the lower air outlet 1b is isolated from the fresh air duct 12; when the lower air outlet control component 20 connects the lower air outlet 1b to the fresh air duct 12, the lower air outlet 1b is isolated from the main duct 11. The control logic of the lower air outlet control component 20 is relatively simple, which can improve the working reliability of the lower air outlet control component 20.

[0063] In the first state, the lower air outlet control component 20, as Figure 3 shown, the lower air outlet 1b is connected to the fresh air duct 12, and the fresh air in the fresh air duct 12 can flow to the lower air outlet 1b, and the lower air outlet 1b conveys fresh air into the room, improving the indoor air quality.

[0064] Optionally, as Figure 3 shown, the main duct 11 can work, and the lower air outlet 1b conveys fresh air into the room. The dotted line with an arrow in the figure represents the direction of air flow. The main air outlet 1a conveys the heat exchange air flow into the room, which can improve the indoor air quality while adjusting the indoor temperature. Optionally, as Figure 4 shown, the main duct 11 does not work, the lower air outlet 1b conveys fresh air into the room, and the main air outlet 1a does not blow air. The dotted line with an arrow in the figure represents the direction of air flow. The air conditioner 100 can convey fresh air alone to adjust the indoor air quality.

[0065] In the second state, the lower air outlet control component 20, as Figure 2 shown, the dotted line with an arrow in the figure represents the direction of air flow. The lower air outlet 1b is connected to the main duct 11, and the heat exchange air flow in the main duct 11 flows to the lower air outlet 1b. Both the main air outlet 1a and the lower air outlet 1b convey the heat exchange air flow into the room. Compared with only blowing air through the main air outlet 1a, the heat exchange air flow delivered downward by the air conditioner 100 can be increased.

[0066] In some embodiments of the present invention, as Figure 5 shown, the lower air outlet control component 20 includes a driving device 3 and a duct valve 4, as Figure 2 and Figure 3As shown, the driving device 3 drives the air duct valve 4 to move between a first position where the lower air outlet 1b is blocked from the main air duct 11 and a second position where the lower air outlet 1b is blocked from the fresh air duct 12. When the air duct valve 4 moves to the first position, the lower air outlet control component 20 presents a first state, and when the air duct valve 4 moves to the second position, the lower air outlet control component 20 presents a second state.

[0067] Only by setting a single air duct valve 4 can the air outlet switching of the lower air outlet 1b be realized. The structure of the lower air outlet control component 20 is simple, which is convenient for the arrangement of the lower air outlet control component 20 and saves manufacturing costs.

[0068] The air duct valve 4 moves between the first position and the second position. Optionally, the air duct valve 4 can rotate between the first position and the second position, or can move according to a predetermined trajectory, etc. The movement form of the air duct valve 4 can be selected according to actual needs.

[0069] In some embodiments of the present utility model, such as Figure 2 and Figure 3 As shown, the air conditioner body 10 includes a communicating air duct 13 communicating with the lower air outlet 1b. The communicating air duct 13 communicates with the main air duct 11 and the communicating air duct 13 communicates with the fresh air duct 12. When the air duct valve 4 moves to the first position, the lower air outlet control component 20 blocks the communicating air duct 13 and the main air duct 11 and conducts the communicating air duct 13 and the fresh air duct 12; when the air duct valve 4 moves to the second position, the lower air outlet control component 20 blocks the communicating air duct 13 and the fresh air duct 12 and conducts the communicating air duct 13 and the main air duct 11.

[0070] In some embodiments of the present utility model, such as Figure 5 As shown, the air duct valve 4 is a rotary valve 41, and the driving device 3 includes a driving motor 31. The driving motor 31 drives the rotary valve 41 to rotate between the first position and the second position.

[0071] The driving motor 31 provides power for the rotation of the rotary valve 41. The rotary valve 41 rotates between the first position and the second position. The movement form of the rotation of the air duct valve 4 is simple and the working reliability is strong.

[0072] In some embodiments of the present utility model, the rotary valve 41 is rotatably arranged in the communicating air duct 13. When the rotary valve 41 is in the first position and the second position, it is located in the communicating air duct 13. The rotation of the rotary valve 41 is not interfered by other components in the air conditioner body 10, which can improve the working reliability of the rotary valve 41.

[0073] In some embodiments of the present utility model, such as Figure 6 and Figure 7 As shown, both ends of the rotary valve 41 in the extending direction of the rotation axis respectively have a connecting shaft portion 411 and a rotating portion 412. Such as Figure 8and Figure 9 As shown in Figure 9 , the driving device 3 includes a mounting base 32. The mounting base 32 includes a base body 32a, and a first end portion 32b and a second end portion 32c provided at both ends of the base body 32a. The driving motor 31 is mounted on the first end portion 32b and is connected to the coupling portion 411, and the rotating portion 412 is rotatably supported on the second end portion 32c.

[0074] The mounting base 32 functions to mount and support. The driving motor 31 and the rotating valve 41 are both mounted on the mounting base 32, and the mounting base 32 is mounted on the air conditioner body 10. The rotating valve 41 is rotatably connected to the mounting base 32. The rotating valve 41 rotates about the straight line where the connection line of the coupling portion 411 and the rotating portion 412 is located. The coupling portion 411 cooperates with the first end portion 32b, and the rotating portion 412 cooperates with the second end portion 32c. The driving motor 31 is provided at the first end portion 32b and is connected to the coupling portion 411. The driving motor 31 drives the rotating valve 41 to rotate, and the rotating portion 412 at the other end in the length direction of the rotating valve 41 is rotatably engaged with the second end portion 32c, so that the rotating valve 41 is rotatably connected to the mounting base 32.

[0075] In some embodiments of the present invention, as Figure 8 shown in Figure 8 , the rotating valve 41 includes a heat insulation member 413 and a support member 414 for carrying the heat insulation member 413. When the air duct valve 4 is in the first position, the heat insulation member 413 blocks the connection between the air duct 13 and the main air duct 11, and the heat insulation member 413 seals and isolates the connection between the air duct 13 and the main air duct 11.

[0076] The support member 414 functions to support. The heat insulation member 413 is provided on the support member 414. Both the coupling portion 411 and the rotating portion 412 are formed on the support member 414, and the driving motor 31 drives the support member 414 to rotate.

[0077] On the one hand, the heat insulation member 413 can play a heat insulation role. When the air duct valve 4 is in the first position, it isolates the main air duct 11 and the air duct 13. The main air duct 11 is used to convey the heat exchange air flow, and there must be a temperature difference between the air duct 13 and the main air duct 11. By providing the heat insulation member 413, the heat exchange between the main air duct 11 and the air duct 13 can be reduced, so that the situation where the air at a higher temperature in the main air duct 11 and the air duct 13 is cooled and liquefied to form condensation can be reduced. By providing the heat insulation member 413, the condensation generated on the rotating valve 41 can be reduced, so that the situation where the condensation gathered on the rotating valve 41 drips into the air conditioner body 10 can be improved, and the working stability of the air conditioner 100 can be enhanced.

[0078] On the other hand, the heat insulation member 413 can also play a sealing role. When the air duct valve 4 is in the first position, the heat insulation member 413 seals off the communication between the air duct 13 and the main air duct 11, which can improve the situation that the heat exchange air flow in the main air duct 11 escapes into the fresh air duct 12 and is lost, and is beneficial to improving the heat exchange air supply volume of the air conditioner 100.

[0079] In some embodiments of the present invention, as Figure 7 shown, the rotating part 412 is a rotating shaft 4120. As Figure 9 shown, a shaft hole 325 is provided on the second end portion 32c, and the rotating shaft 4120 is rotatably supported in the shaft hole 325. As Figure 10 shown, an oil groove 4121 extending along the axial direction of the rotating shaft 4120 is provided on the outer peripheral surface of the rotating shaft 4120. There are a plurality of oil grooves 4121 and they are arranged at intervals along the circumferential direction of the rotating shaft 4120.

[0080] The rotating shaft 4120 and the coupling part 411 are coaxially arranged to improve the rotation stability of the rotating valve 41.

[0081] By providing the oil groove 4121, lubricating oil can be stored in the oil groove 4121, and the lubricating oil is filled between the rotating shaft 4120 and the shaft hole 325, which can reduce the friction between the rotating shaft 4120 and the shaft hole 325, improve the rotation stability of the rotating shaft 4120, and improve the working reliability of the rotating valve 41. And since there are a plurality of oil grooves 4121 arranged at intervals along the circumferential direction of the rotating shaft 4120, the circumferential surface of the rotating shaft 4120 can be evenly covered with lubricating oil, further reducing the friction between the rotating shaft 4120 and the shaft hole 325.

[0082] In some embodiments of the present invention, as Figure 11 shown, the first end portion 32b defines a receiving groove 323. As Figure 12 shown, one side of the receiving groove 323 away from the second end portion 32c is formed as a notch 3231, and a partition wall 3232 is provided on the side of the receiving groove 323 close to the second end portion 32c. An avoidance hole 3233 is formed on the partition wall 3232. The driving motor 31 is adapted to be installed in the receiving groove 323 through the notch 3231, and the output shaft of the driving motor 31 passes through the avoidance hole 3233 and is connected to the coupling part 411.

[0083] The driving motor 31 is assembled in the receiving groove 323, and the receiving groove 323 can support and protect the driving motor 31. The motor shaft of the driving motor 31 passes through the avoidance hole 3233 and is connected to the coupling part 411. When the motor shaft rotates, the rotating valve 41 can be driven to rotate. The aperture of the avoidance hole 3233 is larger than the shaft diameter of the motor shaft to avoid the motor shaft and prevent interference with the rotation of the motor shaft.

[0084] In some embodiments of the present invention, as Figure 12As shown, a motor mounting hole is provided on the partition wall 3232, and a fastener passes through the motor mounting hole to fixedly connect the driving motor 31 to the partition wall 3232.

[0085] In some embodiments of the present utility model, as Figure 13 shown, the air conditioner body 10 includes an air outlet frame 14. The air outlet frame 14 has a through hole 141. The seat body 32a is provided on the rear side of the air outlet frame 14 and is mounted on the air outlet frame 14. The rotating valve 41 extends to the front side of the air outlet frame 14 through the through hole 141, and the first end portion 32b is located on the rear side of the air outlet frame 14.

[0086] When the rotating valve 41 is in the first position and the second position, the rotating valve 41 is located on the front side of the air outlet frame 14. The heat exchange air flow flowing from the main air duct 11 to the lower air outlet 1b flows from the front side of the air outlet frame 14, and the fresh air flowing from the fresh air duct 12 to the lower air outlet 1b also flows from the front side of the air outlet frame 14. Therefore, by mounting the seat body 32a on the rear side of the air outlet frame 14 and extending the rotating valve 41 into the front side of the air outlet frame 14 through the through hole 141, the seat body 32a will not interfere with the air flow, the air resistance of the air flow flowing to the lower air outlet 1b can be reduced, and the fluidity of the air flow can be improved.

[0087] In some embodiments of the present application, as Figure 16 shown, the air conditioner body 10 includes an air outlet frame 14 and a front frame 15. The front frame 15 is provided on the front side of the air outlet frame 14, and the rotating valve 41 is rotatably provided between the air outlet frame 14 and the front frame 15.

[0088] In some embodiments of the present utility model, as Figure 13 and Figure 14 shown, the rear side of the air outlet frame 14 has a surrounding plate 142 that cooperates with the first end portion 32b to close the notch 3231. After the mounting seat 32 is mounted on the air outlet frame 14, the surrounding plate 142 closes the notch 3231 of the receiving groove 323, isolating the receiving groove 323 from the outside, thereby protecting the driving motor 31 located in the receiving groove 323, preventing external pollutants such as water and dust from entering the receiving groove 323, reducing the generation of condensed water on the driving motor 31, and improving the working reliability and safety of the driving motor 31.

[0089] In some examples of the present utility model, as Figure 13 and Figure 14 shown, the air outlet frame 14 is provided with a support rib 1421 connected to the surrounding plate 142. The support rib 1421 intersects with the surrounding plate 142, which can improve the structural strength of the surrounding plate 142, improve the situation where the surrounding plate 142 shakes due to impact and separates from the first end portion 32b, and improve the working reliability of the cooperation between the surrounding plate 142 and the first end portion 32b.

[0090] In some embodiments of the present utility model, asFigure 11 and Figure 12 As shown in Figure 12 , the first end portion 32b has an outgoing wire groove 324 communicating with the notch 3231. The outgoing wire groove 324 includes a plurality of groove segments 3241 arranged in sequence along the extending direction and having different extending directions. As shown in Figure 13 and Figure 14 As shown in Figure 14 , the air outlet frame 14 is provided with a wire clamping buckle 143.

[0091] The wire of the driving motor 31 extends out of the accommodating groove 323 from the outgoing wire groove 324. The outgoing wire groove 324 includes a plurality of groove segments 3241 with different extending directions. The outgoing wire groove 324 can also play a role in limiting the wire, reducing the situation that the wire shakes inside the air conditioner body 10 when being impacted, and improving the regularity of the wire routing. And the air outlet frame 14 is provided with a wire clamping buckle 143. After the wire extends out of the accommodating groove 323 via the outgoing wire groove 324, it is limited by the wire clamping buckle 143, further improving the regularity of the wire routing and the working stability of the driving motor 31.

[0092] In some embodiments of the present utility model, as shown in Figure 11 and Figure 12 As shown in Figure 12 , the outgoing wire groove 324 includes two groove segments 3241. The first groove segment 3241 extends to the notch 3231 and communicates with the notch 3231. The extending direction of the second groove segment 3241 is orthogonal to the extending direction of the first groove segment 3241. The two groove segments 3241 form an L shape.

[0093] When the driving motor 31 is installed into the accommodating groove 323, the wire passes through the notch 3231 and enters the first groove segment 3241, and enters the tail of the second groove segment 3241 along the extending direction of the groove segment 3241. The groove segment 3241 limits the wire, improving the regularity of the wire and preventing the wire from being separated due to impact.

[0094] In some embodiments of the present utility model, as shown in Figure 11 and Figure 14 As shown in Figure 14 , the air conditioner body 10 includes an air outlet frame 14 for carrying the mounting seat 32. The seat body 32a is provided with a clamping portion 321, and the air outlet frame 14 is provided with a clamping structure 144 cooperating with the clamping portion 321.

[0095] The mounting seat 32 and the air outlet frame 14 are clamped and matched, which can reduce the disassembly and assembly difficulty of the mounting seat 32 and improve the assembly efficiency of the mounting seat 32.

[0096] In some embodiments of the present utility model, as shown in Figure 13 As shown in Figure 13 , the clamping structure 144 includes an elastic buckle 1441. As shown in Figure 11 As shown in Figure 11 , a clamping hole 3211 is formed on the clamping portion 321. As shown in Figure 14 As shown in Figure 14 , the elastic buckle of the elastic buckle 1441 passes through the clamping hole 3211 to be clamped with the clamping portion 321.

[0097] The elastic buckle 1441 can generate elastic deformation, and the free end of the elastic buckle 1441 forms a spring buckle. When the spring buckle moves along the clamping hole 3211, the elastic buckle 1441 generates elastic deformation to avoid the relative movement of the clamping portion 321. After the spring buckle passes through the clamping hole 3211, the elastic buckle 1441 returns to its original state, and the spring buckle is clamped with the clamping portion 321 to assemble the mounting seat 32 on the air outlet frame 14.

[0098] In some embodiments of the present invention, Figure 13 As shown, the clamping structure 144 further includes a guide column 1442, which is spaced apart from the elastic buckle 1441, and the spacing direction is orthogonal to the deformation direction of the elastic buckle 1441, as shown in FIG. Figure 14 As shown, the guide post 1442 and the elastic buckle 1441 are inserted into the same clamping hole 3211 .

[0099] The guide column 1442 can play a guiding role. The length of the guide column 1442 extends along the installation direction of the clamping portion 321. The guide column 1442 guides the clamping portion 321 to move relative to the elastic buckle 1441, which can improve the assembly efficiency of the mounting base 32.

[0100] The guide column 1442 and the elastic clip 1441 are arranged at intervals. After the mounting seat 32 and the air outlet frame 14 are snap-fitted and assembled, the guide column 1442 and the elastic clip 1441 are inserted into the same clip hole 3211. The cooperation between the guide column 1442 and the elastic clip 1441 can also limit the mounting seat 32, thereby reducing the shaking of the mounting seat 32 relative to the air outlet frame 14.

[0101] In some embodiments of the present invention, Figure 11 and Figure 14 As shown, the seat body 32a has a connecting portion 322, and the connecting portion 322 is fixedly connected to the air outlet frame 14 through a threaded connector.

[0102] The mounting seat 32 and the air outlet frame 14 are fixedly connected by threaded fasteners, so that the installation stability of the mounting seat 32 can be improved, and the working reliability of the lower air outlet control component 20 can be improved.

[0103] The assembly of the mounting seat 32 and the air outlet frame 14 is first performed by snapping together the snap-fitting portion 321 and the snap-fitting structure 144 to preliminarily connect the mounting seat 32 and the air outlet frame 14; while the snap-fitting portion 321 and the snap-fitting structure 144 are snap-fitting, the guide column 1442 and the snap-fitting structure 144 are jointly positioned in cooperation with the snap-fitting structure 144 to reduce the shaking of the mounting seat 32 relative to the air outlet frame 14; finally, the mounting seat 32 and the air outlet frame 14 are fixedly connected by threaded fasteners, and the mounting seat 32 and the air outlet frame 14 are stably matched, and the snapping and positioning before the fixation by the threaded fasteners can improve the assembly efficiency of the threaded fasteners.

[0104] In some embodiments of the present utility model, as Figure 13 and Figure 14 shown, threaded hole mounting posts 145 are provided on the air outlet frame 14. Threaded holes are provided in the threaded hole mounting posts 145, and mounting holes are provided in the mounting base 32. Threaded fasteners pass through the mounting holes and are in threaded cooperation with the threaded holes to fixedly connect the mounting base 32 and the air outlet frame 14.

[0105] In some embodiments of the present utility model, as Figure 11 shown, the clamping portions 321 and the connecting portions 322 are respectively located on the two width sides of the seat body 32a. There are multiple clamping portions 321 which are arranged at intervals along the length direction of the seat body 32a, and there are multiple connecting portions 322 which are arranged at intervals along the length direction of the seat body 32a.

[0106] By providing multiple clamping portions 321 and connecting portions 322, the connection stability between the mounting base 32 and the air outlet frame 14 can be further improved. And the clamping portions 321 and the connecting portions 322 are respectively arranged on the two width sides of the seat body 32a, which can improve the mounting stability of the mounting base 32 in the width direction of the seat body 32a, and can position the mounting base 32 to reduce the rotation of the mounting base 32 relative to the seat body 32a. The multiple clamping portions 321 are arranged at intervals along the length direction of the seat body 32a, and the multiple connecting portions 322 are arranged at intervals along the length direction of the seat body 32a, which can improve the mounting stability of the mounting base 32 in the length direction of the seat body 32a and reduce the rotation of the mounting base 32 relative to the seat body 32a. And the mutual cooperation of the multiple clamping portions 321 and the multiple connecting portions 322 further improves the mounting stability of the mounting base 32.

[0107] In some embodiments of the present utility model, as Figure 14 shown, there are two clamping portions 321, and the two clamping portions 321 are arranged at intervals along the length direction of the seat body 32a. There are two connecting portions 322, and the two connecting portions 322 are arranged at intervals in the length direction of the seat body 32a.

[0108] In some embodiments of the present utility model, as Figure 15 shown, the air conditioner body 10 includes a front panel 17. The lower air outlet 1b is located below the front panel 17. The main air outlet 1a includes side air outlets 1a1 respectively provided on the left and right sides of the front panel 17. The air conditioner body 10 includes a cross-flow fan 18 with an axis extending vertically. The outlet of the cross-flow fan 18 is communicated with the main air duct 11. The main air duct 11 includes an air outlet section extending towards the left and right sides to be respectively correspondingly communicated with the two side air outlets 1a1.

[0109] The left and right side air outlets 1a1 are respectively arranged on the left and right sides of the front panel 17, so as to improve the air supply range of the air conditioner 100 in the horizontal direction and improve the air supply effect.

[0110] The air outlet of the cross-flow air duct is connected to the main air duct 11. Both the cross-flow air duct and the main air duct 11 extend vertically. Therefore, when the cross-flow air duct supplies air to the left and right side air outlets 1a1 in the horizontal direction, it is the maximum air outlet mode of the air conditioner 100.

[0111] When the main air duct 11 is only connected to the main air outlet 1a, the air conditioner 100 supplies air at the maximum air volume, and the heat exchange speed of the air conditioner 100 with the indoor environment is relatively fast. When the main air duct 11 is connected to both the main air outlet 1a and the lower air outlet 1b at the same time, the air volume delivered downward by the air conditioner 100 increases, which can reduce the air volume directly blowing on the user, reduce the direct blowing feeling of the user, and improve the air supply effect of the air conditioner 100.

[0112] In some embodiments of the present invention, as Figure 4 shown, the fresh air duct 12 includes a front air outlet section 121 extending forward and a rear air outlet section 122 extending backward. The fresh air duct 12 is connected to the lower air outlet 1b through the front air outlet section 121.

[0113] As Figures 2-4 shown, a fresh air outlet 1c is further formed at the rear side of the air conditioner body 10 for the fresh air duct 12, and the rear air outlet section 122 is connected to the fresh air outlet. By providing the fresh air outlet 1c, the air supply mode of the air conditioner 100 can be increased to meet the requirements of different scenarios.

[0114] Next, refer to Figures 2-4 to briefly describe several air supply modes of the air conditioner 100 in an embodiment of the present invention.

[0115] As Figure 2 shown, the lower air outlet 1b is connected to the main air duct 11, and the fresh air duct 12 is only connected to the fresh air outlet 1c. The heat exchange air flow generated by the air conditioner 100 can flow through the main air duct 11 to the lower air outlet 1b. Both the lower air outlet 1b and the main air outlet 1a supply heat exchange air flow to the room, and the fresh air outlet 1c supplies fresh air to the room. The dotted line with arrows in the figure indicates the air flow movement direction. It can improve the indoor air quality while adjusting the indoor temperature, making the indoor air fresher.

[0116] As Figure 3 shown, the lower air outlet 1b is connected to the fresh air duct 12. Both the lower air outlet 1b and the fresh air outlet 1c supply fresh air to the room, and the main air outlet 1a supplies heat exchange air flow to the room. The dotted line with arrows in the figure indicates the air flow movement direction. It can improve the indoor air quality while adjusting the indoor temperature, making the indoor air fresher.

[0117] It should be noted that when the air conditioner 100 is in the air supply mode as Figure 2 shown and as Figure 3The air supply modes shown are all for delivering fresh air into the room while adjusting the indoor temperature, thereby improving the indoor air quality. However, when the air conditioner 100 supplies air in the mode shown in Figure 2 , the amount of fresh air delivered into the room is relatively small, and the heat exchange air flow delivery range of the air conditioner 100 in the vertical direction is larger. While when the air conditioner 100 supplies air in the mode shown in Figure 3 , the amount of fresh air delivered into the room is larger. Therefore, the effects produced by the air supply of the air conditioner 100 are different.

[0118] As Figure 4 shown, the lower air outlet 1b is communicated with the fresh air duct 12, the main duct 11 does not work, the lower air outlet 1b and the fresh air outlet 1c jointly deliver fresh air into the room, and the main air outlet 1a does not blow air. The dotted line with arrows in the figure represents the air flow direction. The air conditioner 100 delivers fresh air alone to adjust the indoor air quality.

[0119] By arranging the lower air outlet 1b at the front side of the air conditioner body 10 and the fresh air outlet 1c at the rear side of the air conditioner body 10, the fresh air supply range is increased, and the indoor air circulation is accelerated. Moreover, the lower air outlet 1b directly delivers fresh air in front of the air conditioner 100, and the fresh air can be directly delivered towards the user, quickly improving the air quality near the user and enhancing the fresh air supply effect.

[0120] In some embodiments of the present utility model, as Figure 17 shown, the air conditioner body 10 further has an upper air outlet 1d higher than the front panel 17, and the upper air outlet 1d is adapted to be communicated with the main duct 11.

[0121] By providing the upper air outlet 1d, the air supply range of the air conditioner 100 in the vertical direction can also be increased, and the air supply effect can be enhanced. When the air conditioner 100 is refrigerating, both the main air outlet 1a and the upper air outlet 1d deliver cold air into the room, and the cold air naturally settles from top to bottom, enhancing the refrigeration effect. And when the main duct 11 is simultaneously communicated with both the main air outlet 1a and the upper air outlet 1d, the air supply volume of the air conditioner 100 delivered upwards increases, and the air supply volume delivered from the main air outlet 1a of the air conditioner 100 decreases, which can improve the situation of cold air directly blowing on the human body and enhance the air supply effect of the air conditioner 100.

[0122] In some embodiments of the utility model, the air conditioner 100 further includes: an upper air outlet control component, which is used to control the opening and closing of the upper air outlet 1d, or to switch the on-off state between the main duct 11 and the upper air outlet 1d.

[0123] The upper air outlet 1d can be selectively communicated with the main air duct 11, so as to cooperate with the air outlet mode of the air conditioner 100 to adjust the air supply position of the air conditioner 100 and improve the air supply effect of the air conditioner 100. The upper air outlet control component controls the opening and closing of the upper air outlet 1d and can also block pollutants such as dust outside the air conditioner 100, improving the cleanliness of the air conditioner 100.

[0124] In some embodiments of the present utility model, the air conditioner body 10 further has an upper air outlet 1d, and the upper air outlet 1d can be selectively communicated with the main air duct 11. By providing the upper air outlet 1d and the lower air outlet 1b that can be selectively communicated with the main air duct 11, the air conditioner 100 can realize multi-mode air supply to meet the requirements of different scenarios.

[0125] Optionally, the lower air outlet 1b is only communicated with the fresh air duct 12, the lower air outlet 1b conveys fresh air to the room, the upper air outlet 1d is communicated with the main air duct 11, and both the upper air outlet 1d and the main air outlet 1a convey the heat exchange air flow to the room. The upper air outlet 1d and the main air outlet 1a convey the heat exchange air flow to the room, which can improve the situation that the heat exchange air flow directly blows on the user's body, while the lower air outlet 1b conveys fresh air to the room and also avoids the core position of the human body. It can improve the indoor air quality while adjusting the indoor temperature, and can also improve the impact feeling of the air flow directly blowing on the human body, enhancing the air supply effect.

[0126] In other embodiments of the present utility model, the air conditioner body 10 further has an upper air outlet 1d and a fresh air outlet 1c. The upper air outlet 1d can be selectively communicated with the main air duct 11, and the fresh air duct 12 is communicated with the fresh air outlet 1c. By providing the upper air outlet 1d and the lower air outlet 1b that can be selectively communicated with the main air duct 11, the air conditioner 100 can realize multi-mode air supply to meet the requirements of different scenarios.

[0127] Optionally, the lower air outlet 1b is only communicated with the fresh air duct 12, both the lower air outlet 1b and the fresh air outlet 1c convey fresh air to the room, the upper air outlet 1d is communicated with the main air duct 11, and both the upper air outlet 1d and the main air outlet 1a convey the heat exchange air flow to the room. The upper air outlet 1d and the main air outlet 1a convey the heat exchange air flow to the room, which can improve the situation that the heat exchange air flow directly blows on the user's body, while the lower air outlet 1b and the fresh air outlet 1c convey fresh air to the room and also avoid the core position of the human body. It can improve the indoor air quality while adjusting the indoor temperature, and can also improve the impact feeling of the air flow directly blowing on the human body, enhancing the air supply effect.

[0128] In some embodiments of the present utility model, as Figure 4 and Figure 16 shown, the air conditioner body 10 includes a fresh air component 16 for conveying outdoor fresh air into the room, and the fresh air component 16 defines a fresh air duct 12.

[0129] In some embodiments of the present utility model, asFigure 4 As shown, the fresh air component 16 includes a filter element 161, a fresh air impeller 162, and a fresh air motor 163. The fresh air component 16 has a fresh air inlet 1e, and the fresh air inlet 1e is located at the rear side of the air conditioner body 10. The filter element 161 is arranged closer to the fresh air inlet 1e relative to the fresh air impeller 162 and the fresh air fan. Outdoor fresh air flows into the fresh air component 16 from the fresh air inlet 1e, and the filter element 161 filters pollutants such as dust in the outdoor fresh air, making the fresh air delivered to the room cleaner. The fresh air motor 163 drives the fresh air impeller 162 to rotate to introduce the outdoor fresh air into the fresh air duct 12.
