[0059] In existing vertical air conditioners, some have vertically arranged air outlets, and the air supply in different areas is achieved through air deflector plates. Some have air outlets provided at both the top and bottom of the body, and there is no air outlet on the front of the body.

[0060] For a vertical air conditioner with a vertically arranged air outlet, the wind will blow directly at the front, which may cause the user to feel uncomfortable due to the direct blowing of cold air. For an air conditioner with air outlets provided at both the top and bottom of the body, there is a problem that there is no air in the front area of the body and the air supply distance is short.

[0061] The present utility model provides an air conditioner cabinet 100.

[0062] Please refer to Figures 1 to 15 , in an embodiment of the present utility model, the air conditioner cabinet 100 includes a housing 10, a drainage component 20, a switch door component 30, and a wind wheel component 40; a wind duct 11 is provided inside the housing, the drainage component 20 is arranged on the air outlet side of the housing 10, the drainage component 20 includes an upper drainage member 21 and a lower drainage member 22 arranged at intervals up and down, the upper drainage member 21 and the lower drainage member 22 enclose to form an air outlet communicating with the wind duct 11, the switch door component 30 includes an air outlet panel 31 arranged at the air outlet, the upper drainage member 21 can move relative to the air outlet panel 31 to form a first air outlet 111, the lower drainage member 22 can move relative to the air outlet panel 31 to form a second air outlet 112, the air outlet panel 31 is provided with a third air outlet 311, and the wind wheel component 40 is arranged inside the wind duct for driving air flow to flow towards the air outlet.

[0063] In the present utility model, the direction towards the air outlet of the air conditioner cabinet 100 is defined as the front, the direction away from the air outlet of the air conditioner cabinet 100 is defined as the rear, the direction towards the top of the air conditioner cabinet 100 is defined as the upper side, and the direction towards the bottom of the air conditioner cabinet 100 is defined as the lower side. The housing 10 is further provided with an air inlet 12, and a heat exchanger 60 is also arranged in the air duct 11. The heat exchanger 60 can be arranged above the air wheel assembly 40. The air inlet 12 is communicated with the air duct 11, and the air inlet 12 can be arranged on the lower side of the housing 10. For example, it can be arranged below the back of the housing 10 or below the side of the housing 10. In this way, the air duct 11 takes in air through the air inlet 12, exchanges heat with the heat exchanger 60 in the air duct 11, and then blows out air through the third air outlet 311, realizing the refrigeration or heating of the air conditioner cabinet 100.

[0064] When the air conditioner cabinet 100 is refrigerating, the upper air guiding member 21 can move relative to the air outlet panel 31, so that the first air outlet 111 between the upper air guiding member 21 and the air outlet panel 31 is opened. During the actual opening process of the first air outlet 111, it can be that the upper air guiding member 21 moves away from the air outlet panel 31 to open the first air outlet 111, or the air outlet panel 31 moves away from the upper air guiding member 21 to open the first air outlet 111, or the upper air guiding member 21 and the air outlet panel 31 move simultaneously to open the first air outlet 111. To ensure the connection stability between the air outlet panel 31 and the housing 10, the present utility model selects the upper air guiding member 21 to move away from the air outlet panel 31 to open the first air outlet 111. When the air wheel assembly 40 drives the air flow in the air duct 11 towards the air outlet, the cooled air after heat exchange inside the air duct 11 can be blown out from the first air outlet 111, realizing long-distance upward air supply. Since cold air is denser than hot air, the cold air supplied at a long distance above the air conditioner cabinet 100 can sink, so that the cold air covers the entire space, avoiding discomfort caused by the direct blowing of cold air on the human body.

[0065] When the air conditioner cabinet 100 is in the heating mode, the lower air deflector 22 can move relative to the air outlet panel 31 to open the second air outlet 112 between the lower air deflector 22 and the air outlet panel 31. During the actual opening process of the second air outlet 112, it can be that the air outlet panel 31 moves away from the lower air deflector 22 to open the second air outlet 112, or the lower air deflector 22 moves away from the air outlet panel 31 to open the second air outlet 112, or the lower air deflector 22 and the air outlet panel 31 move simultaneously to open the second air outlet 112. To ensure the connection stability between the air outlet panel 31 and the housing 10, the present utility model selects the lower air deflector 22 to move away from the air outlet panel 31 to open the second air outlet 112. When the air flow in the air duct 11 is driven towards the air outlet by the operation of the air wheel assembly 40, the hot air after heat exchange in the air duct 11 can be blown out from the second air outlet 112 to achieve long-distance downward air supply. Since hot air has a lower density than cold air, the hot air for long-distance air supply below the air conditioner cabinet 100 can rise from bottom to top to cover the entire enclosed space, so that the hot air covers the entire space from bottom to top, avoiding the discomfort caused by the direct blowing of hot air on the human body.

[0066] In addition, when the air conditioner cabinet 100 is in the cooling and heating modes, auxiliary air outlet can also be carried out through the third air outlet 311 formed on the air outlet panel 31, and a wind guiding structure can also be arranged at the third air outlet 311. In the cooling mode, the third air outlet 311 can blow air upward, and in the heating mode, the third air outlet 311 can blow air downward. While increasing the air outlet coverage range through the third air outlet 311, the direct blowing of air on the human body is avoided.

[0067] Certainly, the air conditioner cabinet 100 can also perform full-speed cooling or full-speed heating. In this state, both the first air outlet 111 and the second air outlet 112 can be opened, and the air wheel assembly 40 operates to drive the heat-exchanged air flow towards the air outlet, so that the air after heat exchange inside the air duct 11 is blown out through the first air outlet 111, the second air outlet 112, and the third air outlet 311, enabling the air flow flowing out of the air conditioner cabinet 100 to cover the upper space, the middle space, and the lower space, realizing the rapid blowing out of the air after heat exchange inside the air conditioner cabinet 100 and covering the entire space, achieving the effect of full-speed cooling or full-speed heating.

[0068] The technical solution of the present utility model is to provide a drainage component with an upper drainage member 21 and a lower drainage member 22 on the air outlet side of the housing 10, a switch door assembly 30 with an air outlet panel 31, and a wind wheel assembly 40 arranged in the air duct to drive the air flow towards the air outlet. When the upper drainage member 21 moves relative to the air outlet panel 31, a first air outlet 111 is formed, and when the lower drainage member 22 moves relative to the air outlet panel 31, a second air outlet 112 is formed. When the first air outlet 111 is opened, the heat-exchanged air flow can be guided to the first air outlet 111 by the wind wheel assembly 40 and flow out from the first air outlet 111. When the second air outlet 112 is opened, the heat-exchanged air flow can be guided to the third air outlet 311 by the wind wheel assembly 40 and flow out from the third air outlet 311, enabling the air conditioner cabinet 100 to blow air obliquely upwards or downwards when discharging air, preventing the air from directly blowing on the human body. And since the third air outlet 311 is provided on the air outlet panel 31, it can cooperate with the first air outlet 111 and / or the second air outlet 112 for air supply, thereby improving the air supply coverage range and enhancing the air supply experience of the air conditioner cabinet 100 when discharging air.

[0069] Referring to Figure 1 、 Figure 5 As shown, in an embodiment of the present utility model, the third air outlet 311 includes a plurality of air outlet micro-holes arranged at intervals.

[0070] Among them, when the third air outlet 311 is provided with a plurality of micro-holes arranged at intervals, when the third air outlet 311 is opened for auxiliary air supply, invisible air supply can be realized. When using the third air outlet 311 to improve the air supply range of the air conditioner cabinet 100, it can prevent the air from directly blowing on the human body and causing discomfort.

[0071] In an embodiment of the present utility model, the air outlet panel 31 is fixedly connected to the housing, and the switch door assembly 30 further includes a movable plate member 32 movably installed on the air outlet panel 31, and the movable plate member 32 is used to open and close the third air outlet 311.

[0072] With this arrangement, the third air outlet 311 can be independently opened and closed. When the air conditioner cabinet 100 is not in operation, the third air outlet 311 can be covered to prevent dust in the external environment from entering the air duct 11. And since the movable plate member 32 is provided to open and close the third air outlet 311, when the air conditioner cabinet 100 is discharging air, any one or more of the first air outlet 111, the second air outlet 112, and the third air outlet 311 can be independently controlled for air supply, thereby improving the diversity of the air outlet modes of the air conditioner cabinet 100.

[0073] Referring to Figure 5 、 Figure 7 、 Figure 9As shown, in the embodiment of the present utility model, the air outlet panel 31 includes a first air outlet panel 33 and a second air outlet panel 34. The first air outlet panel 33 is located on the side of the second air outlet panel 34 facing the air duct 11. The third air outlet 311 is provided on the second air outlet panel 34. The first air outlet panel 33 is provided with an air passing opening 314 for communicating the air duct 11 with the third air outlet 311. The first air outlet panel 33 and the second air outlet panel 34 enclose a guiding cavity 315, and the movable plate member 32 is arranged in the guiding cavity 315; and / or

[0074] The movable plate member 32 includes a first movable plate 321 and a second movable plate 322. The first movable plate 321 and the second movable plate 322 can move relative to each other along the guiding cavity 315 to open and close the third air outlet 311.

[0075] With such a setting, the movement of the movable plate member 32 can be guided through the guiding cavity 315, so that the first movable plate 321 and the second movable plate 322 constituting the movable plate member 32 can move in a limited manner along a predetermined track to open and close the third air outlet 311. In addition, by enclosing the guiding cavity 315 with the first air outlet panel 33 and the second air outlet panel 34 to accommodate the movable plate member 32, the exposure of the movable plate member 32 can be avoided, which affects the aesthetics of the air conditioner cabinet 100.

[0076] Among them, the first movable plate 321 and the second movable plate 322 can move relative to each other in the up and down direction to open and close the third air outlet 311, or the first movable plate 321 and the second movable plate 322 can move relative to each other in the left and right direction to open and close the third air outlet 311, or the first movable plate 321 and the second movable plate 322 can move relative to each other in other directions to open and close the third air outlet 311, which is not specifically limited here.

[0077] Alternatively, in other embodiments, the movable plate member 32 can also only include one movable plate, and the single movable plate moves along the guiding cavity 315 to realize the opening and closing of the third air outlet 311.

[0078] Or, in another embodiment, the guiding cavity 315 can also be not provided. The movable plate member 32 can be hingedly installed on the housing 10 or the air outlet panel 31, and the third air outlet 311 is opened and closed by rotating the movable plate member 32.

[0079] Continue to refer to Figure 5 、 Figure 7 、 Figure 9 , in the embodiment of the present utility model, the switch door assembly 30 further includes a first switch door driving member 35 and a second switch door driving member 36;

[0080] The first switch door driving member 35 is used to drive the first movable plate 321 to move along the guiding cavity 315 to open and close the third air outlet 311, and / or, the second switch door driving member 36 is used to drive the second movable plate 322 to move along the guiding cavity 315 to open and close the third air outlet 311.

[0081] With such an arrangement, the first movable plate 321 and the second movable plate 322 can be independently driven to move along the guiding cavity 315 to realize the opening and closing of the third air outlet 311, or one of the first movable plate 321 and the second movable plate 322 is driven to move along the guiding cavity 315, and the other can be moved in the guiding cavity 315 by manual operation to open and close the third air outlet 311. No limitation is made here.

[0082] In the above embodiment, the first switch door driving member 35 may include a switch motor 351 and a transmission gear 352. The transmission gear 352 is installed on the transmission shaft of the switch motor 351. The first switch door driving member 35 can be arranged on the side of the first air outlet panel 33 facing the air duct 11. A rack portion 3211 is arranged on the side of the first movable plate 321 facing the air duct 11. The first transmission gear 352 can penetrate into the guiding cavity 315 and be in transmission cooperation with the rack portion 3211. By driving the transmission gear 352 to rotate through the switch motor 351, the first movable plate 321 is driven to move along the guiding cavity 315 to perform the opening and closing action of the third air outlet 311.

[0083] Among them, the switch motor 351 can adopt a stepping motor or a servo motor, so that the starting position and the ending position of the operation of the first movable plate 321 can be more accurately guaranteed. In addition, guiding members 331 can be arranged on both sides of the first air outlet panel 33. The guiding members 331 can be partially accommodated in the guiding cavity 315. A guiding track 3311 arranged along the moving direction of the first movable plate 321 can be opened on the part of the guiding member 331 located in the guiding cavity 315. Guide posts 3212 can be arranged on both sides of the first movable plate 321. The guide posts 3212 are matched with the guiding track 3311, so that when the first movable plate 321 moves in the guiding cavity 315, it can move along the guiding track 3311, thereby ensuring the moving accuracy of the first movable plate 321 and preventing the first movable plate 321 from being disconnected from the first switch door driving member 35.

[0084] In the above embodiment, the second switch door driving member 36 can adopt the same driving structure as the first switch door driving member 35, and the cooperation mode between the second switch door driving member 36 and the second movable plate 322 can be the same as the cooperation mode between the first switch door driving member 35 and the first movable plate 321. In this way, the types of structures of the switch door assembly 30 can be reduced, thereby reducing the layout cost of the movable plate member 32.

[0085] Of course, in other embodiments, the first door opening and closing driving member 35 and / or the second door opening and closing driving member 36 may also adopt a ball screw driving structure, a belt linear driving structure, or a gear chain driving structure, which are not limited herein.

[0086] Referring to Figure 4 、 Figure 7 As shown in the embodiments of the present invention, the upper air guiding member 21 is movably connected to the housing 10, and the upper air guiding member 21 has a first position and a second position;

[0087] When the upper air guiding member 21 is in the first position, the upper air guiding member 21 and the air outlet panel 31 enclose to form the first air outlet 111, and a first acceleration flow channel 13 that connects the first air outlet 111 and the air duct 11. When the upper air guiding member 21 is in the second position, the upper air guiding member 21 cooperates with the air outlet panel 31 to close the first air outlet 111.

[0088] In the above embodiments, the upper air guiding member 21 can be movably connected to the housing 10 through the upper air guiding driving member 23. The upper air guiding driving member 23 is drivingly connected to the upper air guiding member 21, so that the upper air guiding member 21 has a first position that cooperates with the air outlet panel 31 to form the first air outlet 111, and a second position that cooperates with the air outlet panel 31 to close the first air outlet 111.

[0089] Among them, the upper air guiding driving member 23 can be set as an upper driving motor and a connecting rod assembly. The upper air guiding member 21 can be set as an upper air guiding plate. The position of the upper air guiding plate near the upper edge of the air outlet can be rotatably connected to the inner edge of the air outlet through a first rotating shaft. The upper driving motor and the connecting rod assembly can be installed at the air outlet position through a mounting bracket. The upper driving motor drives and connects the end of the upper air guiding member 21 far from its rotation, so that the upper air guiding member 21 can swing around the first rotating shaft and abut against the air outlet panel 31, so that it is in the second position that cooperates with the air outlet panel 31 to close the first air outlet 111, or the upper air guiding member 21 can swing backward around the rotating shaft, so that it is in the first position that cooperates with the air outlet panel 31 to form the first air outlet 111.

[0090] Moreover, when the upper air guiding member 21 is in the first position, it can also cooperate with the air outlet panel 31 to form a first acceleration flow channel 13 connecting the first air outlet 111, so that the air flowing out of the first air outlet 111 can be accelerated, thereby making the air supply distance of the first air outlet 111 farther and enabling the air conditioner cabinet 100 to achieve long-distance air supply.

[0091] Continuing to refer to Figure 4 、 Figure 7, in an embodiment of the present utility model, a first guiding surface 211 is formed on a surface of the upper air guiding member 21 facing the air outlet panel 31. When the upper air guiding member 21 is in the first position, the first guiding surface 211 extends obliquely upward toward the air outlet side of the housing 10 from bottom to top; and / or

[0092] A first guiding portion 312 is provided on a side of the air outlet panel 31 facing the air duct 11, and the first guiding portion 312 is inclined downward from top to bottom toward the air outlet side of the housing 10.

[0093] With such a setting, when a first acceleration flow channel 13 is formed by enclosing the upper air guiding member 21 and the air outlet panel 31, both the first guiding surface 211 serving as the upper side wall of the first acceleration flow channel 13 and the first guiding portion 312 serving as the lower side wall of the first acceleration flow channel 13 extend obliquely upward toward the front end of the housing 10 from bottom to top. Thus, both the upper side wall and the lower side wall of the first acceleration flow channel 13 can guide the air flow in the first acceleration flow channel 13, so that the first acceleration flow channel 13 blows air obliquely upward toward the first air outlet 111, enabling the flow path of the air flow blown out from the first air outlet 111 to be set along a parabola, thereby meeting the requirement that the air flow flowing out from the first air outlet 111 can be blown out obliquely upward.

[0094] Among them, the first guiding portion 312 can be provided at the upper end of the surface of the air outlet panel 31 facing the air duct 11. When the air outlet panel 31 is formed by enclosing a first air outlet panel 33 and a second air outlet panel 34, the first guiding portion 312 can be provided at the upper end of the surface of the first air outlet panel 33 facing the air duct 11. And since the first guiding portion 312 extends obliquely upward toward the air outlet side of the housing 10 from bottom to top, the first air outlet panel 33 is bent at the position of the first guiding portion 312. Thus, when the first air outlet panel 33 and the second air outlet panel 34 are connected to form the air outlet panel 31, a gap is formed between them to form a guiding cavity 315.

[0095] Continue to refer to Figure 4 、 Figure 7 , in an embodiment of the present utility model, a concave surface 2111 is formed by the portion of the first guiding surface 211 away from the air outlet panel 31 recessing toward the inside of the housing 10; and / or

[0096] The included angle between the tangent line at the upper end of the first guiding surface 211 and the vertical direction is α, where α is not less than 40 degrees and α is not greater than 60 degrees.

[0097] In the above embodiments, when the concave surface 2111 is provided, the concave surface 2111 can be made relatively farther from the extension line of the first guiding portion 312. When the first guiding surface 211 and the first guiding portion 312 enclose the first acceleration flow channel 13, the shortest distance from the first guiding surface 211 to the extension line of the first guiding portion 312 gradually decreases first and then gradually increases from the input end to the output end of the first acceleration flow channel 13. The first acceleration flow channel 13 is in a state of being narrow in the middle and wide at both ends, and the first acceleration flow channel 13 as a whole is in a constricted neck shape. The openings at both ends of the first acceleration flow channel 13 are large, and the middle position is slightly smaller. When air flows into the first acceleration flow channel 13, it can be accelerated through the relatively narrow part in the middle. In this way, the blown air flow can be accelerated, so as to realize air supply over a longer distance.

[0098] In addition, in other embodiments, a convex surface located on the first guiding surface 211 can also be provided below the concave surface 2111. The convex surface is relatively closer to the extension line of the first guiding portion 312, so that the first acceleration flow channel 13 can be further in a state of having large openings at both ends and a slightly smaller middle position, and the acceleration effect of the first acceleration flow channel 13 can be improved.

[0099] In the above embodiments, the angle α between the tangent line at the upper end of the first guiding surface 211 and the axis of the air conditioner cabinet 100 can be selected as 40 degrees, 50 degrees, 60 degrees, 70 degrees, etc. In this embodiment, the angle α is selected as 60 degrees.

[0100] With such a setting, the angle at which the air flow in the air duct 11 blows out from the first air outlet 111 will not be too large or too small. When the first guiding surface 211 has a concave surface 2111 and the first guiding surface 211 is in an overall "S" shape, the flow path of the air flow blown out from the first air outlet 111 after being guided by the first guiding surface 211 can be set in a parabolic shape. In this way, the air supply distance of the air conditioner cabinet 100 through the first acceleration flow channel 13 can be further improved.

[0101] In the embodiments of the present utility model, the cross-sectional area of the first acceleration flow channel 13 decreases from both ends of the first acceleration flow channel 13 to the middle of the first acceleration flow channel 13.

[0102] It can be understood that the change of the cross-sectional area of the first acceleration flow channel 13 from both ends to the middle can be a stepped reduction setting, or a more smooth gradual reduction setting from both ends to the middle, as long as the first acceleration flow channel 13 has a structure that is wide at both ends and narrow in the middle, and no limitation is made here.

[0103] With such a setting, when the first acceleration flow channel 13 passes air, the air flow can be accelerated through the relatively narrow position in the middle, so as to increase the flow velocity of the air flow at the end of the first acceleration flow channel 13 and increase the air outlet distance of the first air outlet 111.

[0104] Refer to Figure 6 、 Figure 7 As shown, in the embodiment of the present utility model, the wind wheel assembly 40 includes a first wind wheel assembly 41 disposed in the air duct 11. The first wind wheel assembly 41 is correspondingly arranged at the first air outlet 111. The first wind wheel assembly 41 includes a first volute 411, a first volute tongue 412, and a first cross-flow fan 413. The first volute 411 and the first volute tongue 412 cooperate to form a first air passage 414 communicating with the first acceleration flow passage 13, and the first cross-flow fan 413 is disposed in the first air passage 414.

[0105] With such a setting, the air flow direction inside the air duct 11 can be guided through the first air passage 414, and the air intake volume of the first acceleration flow passage 13 can be increased. Among them, the first volute 411 and the first volute tongue 412 can be inclined from bottom to top toward the air outlet side of the housing 10, so that the first wind wheel assembly 41 can blow air obliquely from bottom to top toward the air outlet side of the housing 10, thereby ensuring that the overall air outlet direction of the first wind wheel assembly 41 is consistent with that of the first acceleration flow passage 13.

[0106] In the above embodiment, the cross-sections of the first volute 411 and the first volute tongue 412 can both be in a spiral shape. When the first volute 411 and the first volute tongue 412 enclose to form the first air passage 414, the air flow direction in the first air passage 414 can be in a spiral shape. Thus, when the air flow flows inside the first air passage 414, the flow resistance of the air flow in the first air passage 414 can be reduced. And since there is a first cross-flow fan 413 disposed in the first air passage 414, the air flow in the first air passage 414 can be further accelerated, so that the first acceleration flow passage 13 can accelerate and introduce the air flow through the first air passage 414, thereby ensuring the long-distance air supply effect of the first air outlet 111.

[0107] Continue to refer to Figure 6 、 Figure 7 , in the embodiment of the present utility model, the first volute tongue 412 and the first volute 411 are spaced apart from top to bottom. When the upper air guiding member 21 is in the first position, the upper air guiding member 21 abuts against the first volute tongue 412 to connect the first acceleration flow passage 13 and the first air passage 414.

[0108] With such a setting, when the first acceleration flow channel 13 is opened, the upper air guiding member 21 can be overlapped with the first volute tongue 412, and the upper air guiding member 21 is connected to the first volute tongue 412. The gap between the upper air guiding member 21 and the first volute tongue 412 is small or there is no gap, and the two can be in close contact. With such a setting, the air flow blown upward from the first air passing channel 414 is basically blocked by the upper air guiding member 21, ensuring that the air flow can be guided by the upper air guiding member 21. The air flow blown upward from the first air passing channel 414 can basically all flow out from the first acceleration flow channel 13, which helps to maintain the air volume and air speed of the first acceleration flow channel 13.

[0109] Continue to refer to Figure 6 、 Figure 7 In the embodiment of the present utility model, the first volute 411 and the air outlet panel 31 cooperate to form a first air guiding channel 15. When the upper air guiding member 21 is in the first position, the first air guiding channel 15 is used to guide the air flow in the air duct 11 to the first acceleration flow channel 13.

[0110] In the above embodiment, due to the guiding effect of the first cross-flow fan 413, the air inside the air duct 11 flows towards the direction of the first cross-flow fan 413. When the air flows upward from the first volute 411, since the outer shape of the first volute 411 can be in a spiral shape and has a guiding effect, and due to the limitation of the air outlet panel 31, a first air guiding channel 15 is formed between the first volute 411 and the air outlet panel 31. The air flowing upward through the outer wall of the first volute 411 is guided by the first air guiding channel 15 and flows towards the first acceleration flow channel 13, thereby realizing an increase in the air volume of the first acceleration flow channel 13, improving the air pressure of the first acceleration flow channel 13. When the first acceleration flow channel 13 can accelerate the air flow, the air flow blown out from the first air outlet 111 has a farther blowing distance.

[0111] Refer to Figure 4 、 Figure 8 、 Figure 9 As shown in

[0112] When the lower air guiding member 22 is in the third position, the lower air guiding member 22 and the air outlet panel 31 cooperate to form the second air outlet 112 and a second acceleration flow channel 14 that connects the second air outlet 112 and the air duct 11. When the lower air guiding member 22 is in the fourth position, the lower air guiding member 22 and the air outlet panel 31 cooperate to close the second air outlet 112.

[0113] In the above embodiments, the lower air guiding member 22 can be movably connected to the housing 10 through the lower air guiding driving member 24. The lower air guiding driving member 24 is drivingly connected to the lower air guiding member 22, so that the lower air guiding member 22 has a third position for cooperating with the air outlet panel 31 to form the second air outlet 112, and a fourth position for cooperating with the air outlet panel 31 to close the second air outlet 112.

[0114] Referring to Figure 14 , Figure 15 As shown, the lower air guiding driving member 24 can be set as a lower driving motor 242 and a driving shaft rod 241. The lower air guiding member 22 can be set as a lower air guiding plate. A second rotating shaft 222 is arranged at a position of the lower air guiding plate close to the lower edge of the air outlet, and the second rotating shaft 222 can be rotatably connected to the inner edge of the air outlet. There are two sets of the lower driving motor 242 and the driving shaft rod 241, and the two sets of the lower driving motor 242 and the driving shaft rod 241 can be respectively arranged close to the inner walls on both sides of the housing 10. One end of the driving shaft rod 241 is connected to the lower air guiding plate, and the other end is connected to the output end of the lower driving motor 242. By driving the driving shaft rod 241 to extend and retract by the lower driving motor 242, the lower air guiding plate is pushed to swing forward around the second rotating shaft 222, so that it is in the fourth position for cooperating with the air outlet panel 31 to close the second air outlet 112. Or the lower air guiding member 22 can swing backward around the second rotating shaft 222, so that the upper end of the lower air guiding plate abuts against the second volute tongue 422, and cooperates with the air outlet panel 31, so that it is in the third position for cooperating with the air outlet panel 31 to form the second air outlet 112.

[0115] Optionally, a connecting shaft 223 is arranged at the position where the lower air guiding plate is connected to the driving shaft rod 241, and a socket part 243 with a long strip-shaped slot is arranged at the end of the driving shaft rod 241. The lower air guiding plate is socketed and cooperated with the socket part 243 through the connecting shaft 223, and can move up and down in the socket part 243. When the lower driving motor 242 drives the lower air guiding member 22 to swing, a certain movement margin can be provided for the connection position between the lower air guiding member 22 and the driving shaft rod 241.

[0116] In the above embodiments, the upper driving motor can be set as a stepping motor, which can perform servo control on the opening and closing angle of the upper air guiding member 21, so that the action of the upper air guiding member 21 is more accurate. The lower driving motor 242 can also be set as a stepping motor to perform servo control on the opening and closing angle of the lower air guiding member 22, ensuring that the opening and closing action of the lower air guiding member 22 is more accurate.

[0117] Moreover, when the lower air guiding member 22 is in the third position, it can also cooperate with the air outlet panel 31 to form a second acceleration flow channel 14 connecting the second air outlet 112, so that the air flowing out of the second air outlet 112 can be accelerated, thereby making the air supply distance of the second air outlet 112 farther and enabling the air conditioner cabinet 100 to achieve long-distance air supply.

[0118] Continue to refer to Figure 4 、 Figure 8 、 Figure 9 In an embodiment of the present invention, a second guiding surface 221 is formed on a surface of the lower air guiding member 22 facing the air outlet panel 31. When the lower air guiding member 22 is in the third position, the second guiding surface 221 extends obliquely downward from top to bottom towards the air outlet side of the housing 10; and / or

[0119] A second guiding portion 313 is provided on a side of the air outlet panel 31 facing the air duct 11, and the second guiding portion 313 extends obliquely downward from top to bottom towards the air outlet side of the housing 10.

[0120] In the above embodiment, similar to the cooperation between the upper air guiding member 21 and the air outlet panel 31, when the second acceleration flow channel 14 is formed by enclosing the lower air guiding member 22 and the air outlet panel 31, the second guiding surface 221 serving as the lower side wall of the second acceleration flow channel 14 and the second guiding portion 313 serving as the upper side wall of the second acceleration flow channel 14 both extend obliquely downward from top to bottom towards the air outlet side of the housing 10. In this way, both the lower side wall and the upper side wall of the second acceleration flow channel 14 can guide the air flow passing through the second acceleration flow channel 14, so that the second acceleration flow channel 14 blows air obliquely downward towards the second air outlet 112. The air flow path blown out from the second air outlet 112 extends obliquely downward and can advance forward along the ground, thereby meeting the requirement that the air flow flowing out from the first air outlet 111 can blow out obliquely downward.

[0121] Among them, the second guiding portion 313 can be provided at the lower end of the surface of the air outlet panel 31 facing the air duct 11. When the air outlet panel 31 is formed by enclosing the first air outlet panel 33 and the second air outlet panel 34, the second guiding portion 313 can be provided at the lower end of the surface of the first air outlet panel 33 facing the air duct 11. And since the second guiding portion 313 extends obliquely downward from top to bottom towards the air outlet side of the housing 10, the first air outlet panel 33 is bent at the position of the second guiding portion 313. In this way, when the first air outlet panel 33 and the second air outlet panel 34 are connected to form the air outlet panel 31, there is a gap between them to form a guiding cavity 315.

[0122] Refer to Figure 8 、 Figure 9 As shown, in an embodiment of the present invention, the lower end of the second guiding surface 221 is bent upward to form a blowing extension portion 2211; and / or

[0123] The included angle between the tangent line of the lower end of the second guiding surface 221 and the vertical direction is β, where β is not less than 10 degrees and β is not greater than 45 degrees.

[0124] In the above embodiments, when the air supply extension part 2211 is provided, when guiding air from the second acceleration flow channel 14 out of the second air outlet 112 through the second guiding surface 221, the air supply extension part 2211 at the end part of the second guiding surface 221 can change the air flow direction. Guided by the air supply extension part 2211, the air flow turns and rises, avoiding the air flow blown out from the second acceleration flow channel 14 directly blowing to a position closer to the air conditioner cabinet 100 on the ground, thereby achieving a longer air supply distance and avoiding the influence on the air supply range of the air conditioner cabinet 100 when supplying air through the second acceleration flow channel 14.

[0125] In addition, the air supply extension part 2211 is formed by bending upward from the lower end of the second guiding surface 221. When guiding the air flow through the lower air guiding member 22, the wind resistance encountered by the air flow flowing from the second guiding surface 221 to the air supply extension part 2211 can be reduced, thereby also avoiding the influence on the air supply distance.

[0126] In the above embodiments, when the air supply extension part 2211 is provided, the tangent line at the lower end of the second guiding surface 221 can be the tangent line at the end of the air supply extension part 2211, and the included angle between the tangent line at the end of the air supply extension part 2211 and the axis of the air conditioner cabinet 100 can be 10 degrees, 20 degrees, 30 degrees, 40 degrees or 45 degrees. No matter how it is set, it can avoid the position where the air flow blown out from the second air outlet 112 contacts the ground being too close to the air conditioner cabinet 100, resulting in too short an air supply distance of the air flow blown out from the second air outlet 112, or avoid the position where the air flow blown out from the second air outlet 112 contacts the ground being too far from the air conditioner cabinet 100, resulting in the air flow blown out from the second air outlet 112 possibly directly blowing on the human body and causing discomfort.

[0127] In other embodiments, when the air supply extension part 2211 is not provided, the included angle between the tangent line at the lower end of the second guiding surface 221 and the axis of the air conditioner cabinet 100 can directly be the included angle between the second guiding surface 221 and the axis of the air conditioner cabinet 100, which is not limited herein.

[0128] Continue to refer to Figure 8 、 Figure 9 In the embodiments of the present utility model, the impeller assembly 40 includes a second impeller assembly 42 disposed in the air duct 11. The second impeller assembly 42 is disposed corresponding to the second air outlet 112. The second impeller assembly 42 includes a second volute 421, a second volute tongue 422 and a second cross-flow fan 423. The second volute 421 and the second volute tongue 422 cooperate to form a second air passage 424 communicating with the second acceleration flow channel 14, and the second cross-flow fan 423 is disposed in the second air passage 424.

[0129] Among them, the second volute 421 and the second volute tongue 422 can be inclined downward toward the air outlet side of the housing 10, so that the second impeller assembly 42 can blow air inclined downward toward the air outlet side of the housing 10, thereby ensuring that the overall air outlet direction of the second impeller assembly 42 is consistent with that of the second acceleration flow channel 14.

[0130] With such a setting, the air flow direction inside the air duct 11 can be guided through the second air passing duct 424, and the air inflow volume of the second acceleration flow channel 14 can be increased. Among them, the cross-sections of the second volute 421 and the second volute tongue 422 can both be spiral-shaped. When the second volute 421 and the second volute tongue 422 enclose to form the second air passing duct 424, the air flow direction in the second air passing duct 424 can be spiral-shaped. Thus, when the air flow flows inside the second air passing duct 424, the flow resistance of the air flow in the second air passing duct 424 can be reduced, and since the second cross-flow fan 423 is arranged in the second air passing duct 424, the air flow in the second air passing duct 424 can be further accelerated, so that the second acceleration flow channel 14 can accelerate and introduce the air flow through the second air passing duct 424, thereby ensuring the long-distance air supply effect of the second air outlet 112.

[0131] Continue to refer to Figure 8 、 Figure 9 , in the embodiment of the present invention, the second volute 421 and the second volute tongue 422 are arranged at intervals from top to bottom. When the lower drainage member 22 is in the third position, the lower drainage member 22 abuts against the second volute tongue 422, so that the second acceleration flow channel 14 is connected to the second air passing duct 424;

[0132] And / or, the cross-sectional area of the second acceleration flow channel 14 is set to decrease from both ends of the second acceleration flow channel 14 to the middle of the second acceleration flow channel 14.

[0133] With such a setting, when the second acceleration flow channel 14 is opened, the lower drainage member 22 can overlap with the second volute tongue 422, and the lower drainage member 22 and the second volute tongue 422 are connected. The gap between the lower drainage member 22 and the second volute tongue 422 is small or there is no gap, and the two can be closely abutted. With such a setting, the air flow blown downward from the second air passing duct 424 is basically blocked by the lower drainage member 22, so as to ensure that the air flow can be drained by the lower drainage member 22, and the air flow blown downward from the second air passing duct 424 can basically completely flow out from the second acceleration flow channel 14, which helps to maintain the air volume and air speed of the second acceleration flow channel 14.

[0134] In addition, the change in the cross-sectional area of the second acceleration channel 14 can also adopt a manner similar to that of the first acceleration channel 13, that is, the cross-sectional area of the second acceleration channel 14 is set to decrease from both ends of the second acceleration channel 14 to the middle of the second acceleration channel 14. In this way, the flowing gas in the second acceleration channel 14 can be accelerated through a narrower part, so that the air flow blown out from the second air outlet 112 can also achieve a longer-distance air supply.

[0135] It can be understood that the change in the cross-sectional area of the second acceleration channel 14 from both ends to the middle can be set to decrease step by step, or can be set to gradually decrease more smoothly from both ends to the middle. As long as the first acceleration channel 13 presents a structure with a wide middle and a narrow middle, it is not limited here.

[0136] Continue to refer to Figure 8 、 Figure 9 , in the embodiment of the present invention, the air outlet panel 31 and the second volute 421 cooperate to form a second diversion channel 16. When the lower diversion member 22 is in the third position, the second diversion channel 16 is used to direct the air flow in the air duct 11 to the second acceleration channel 14.

[0137] Similar to the function of the first diversion channel 15, due to the diversion effect of the second cross-flow fan 423, the air inside the air duct 11 flows towards the direction of the second cross-flow fan 423. When the air flows downward from the second volute 421, since the outer shape of the second volute 421 can be spiral-shaped, it has a diversion effect. And, due to the limitation of the air outlet panel 31, a second diversion channel 16 is formed between the second volute 421 and the air outlet panel 31. Therefore, the air flowing downward through the outer wall of the second volute 421 is diverted by the second diversion channel 16 and flows towards the second acceleration channel 14, thereby realizing an increase in the air volume of the second acceleration channel 14 and improving the air pressure of the second acceleration channel 14. When the second acceleration channel 14 can accelerate the air flow, the air flow blown out from the second acceleration channel 14 has a longer air supply distance.

[0138] Refer to Figure 6 、 Figure 8 、 Figure 10 As shown in

[0139] In the above embodiments, the induced draft fan 50 can be arranged below the heat exchanger 60 and is used to introduce external air from the air inlet 12 into the air duct 11. By arranging the induced draft fan 50, sufficient air pressure and air volume can be provided for the air circulation inside the air duct 11, so that when the first wind wheel assembly 41 and the second wind wheel assembly 42 are working, there is sufficient air intake. At the same time, the induced draft fan 50 can assist the air outlet of the first air outlet 111 and the second air outlet 112, and speed up the air flow in the first acceleration flow channel 13 and the second acceleration flow channel 14.

[0140] Moreover, due to the arrangement of the induced draft fan 50, when air enters the air duct 11 from the starting end of the air duct 11, power for air flow can be provided for the air outlet of the third air outlet 311, so that the third air outlet 311 can also assist in air outlet.

[0141] Continue to refer to Figure 6 、 Figure 8 、 Figure 10 In the present utility model, the heat exchanger 60 includes a first heat exchange part and a second heat exchange part which are connected to each other, and a connection included angle is formed between the first heat exchange part and the second heat exchange part, and the connection included angle is an acute angle.

[0142] With such an arrangement, when the induced draft fan 50 is drawing in air, the contact area between the heat exchanger 60 and the incoming air can be increased, thereby improving the heat exchange effect. When the present utility model can realize long-distance inclined air supply at the upper part, normal air supply in the middle, and long-distance inclined air supply at the lower part, the air conditioner cabinet 100 can have sufficient cooling capacity or heating capacity, so as to ensure the cooling air outlet or heating air outlet effect of the air conditioner cabinet 100.

[0143] In the above embodiments, the connection part of the first heat exchange part and the second heat exchange part is located below the air conditioner cabinet 100. The air conditioner cabinet 100 further includes a water receiving tray, the water receiving tray is arranged between the heat exchanger 60 and the induced draft fan 50, and the connection part of the first heat exchange part and the second heat exchange part is arranged in the water receiving tray.

[0144] With such an arrangement, the condensed water generated when the heat exchanger 60 exchanges heat can flow into the water receiving tray along the heat exchanger 60, and the water receiving tray does not need to be set with a sufficient width, thereby avoiding the water receiving tray from blocking the air flow inside the air duct 11.

[0145] Continue to refer to Figure 6 、 Figure 8 、 Figure 10, in an embodiment of the present utility model, the air conditioner cabinet 100 has a first cooling mode and a second cooling mode. When the air conditioner cabinet 100 is in the first cooling mode, the air conditioner cabinet 100 blows air from the first air outlet 111 and the third air outlet 311. When the air conditioner cabinet 100 is in the second cooling mode, the air conditioner cabinet 100 blows air from the first air outlet 111, the second air outlet 112, and the third air outlet 311; and / or

[0146] The air conditioner cabinet 100 has a heating mode. When the air conditioner cabinet 100 is in the heating mode, the air conditioner cabinet 100 blows air from the second air outlet 112 and the third air outlet 311.

[0147] Among them, the first cooling mode is a conventional cooling mode. During operation, the first air wheel assembly 41 and the induced draft fan 50 operate, and air is blown out through the first air outlet 111 and the third air outlet 311. The third air outlet 311 blows air without feeling through the air outlet micropores; the second cooling mode is a full-speed cooling mode. During operation, the first air wheel assembly 41, the second air wheel assembly 42, and the induced draft fan 50 all operate, and air is blown out through the first air outlet 111, the second air outlet 112, and the third air outlet 311. The third air outlet 311 blows air without feeling through the air outlet micropores. The air conditioner cabinet 100 operates in the full-speed cooling mode to achieve large-volume air blowing.

[0148] When the air conditioner cabinet 100 is in the heating mode, the second air wheel assembly 42 and the induced draft fan 50 operate. The second air outlet 112 is opened to achieve inclined downward long-distance air supply, and the third air outlet 311 is opened. The third air outlet 311 blows air without feeling through the air outlet micropores. Since the density of hot air is smaller than that of cold air, the blown hot air covers the entire indoor space from bottom to top.

[0149] In addition, in other embodiments, the air conditioner cabinet 100 may also have a full-speed heating mode. At this time, the first air outlet 111, the second air outlet 112, and the third air outlet 311 are all opened, and the first air wheel assembly 41, the second air wheel assembly 42, and the induced draft fan 50 all operate, and the hot air in the air duct 11 can be quickly exported to the room.
