[0069] In the existing vertical air conditioners, there are those with vertically arranged air outlets, and the air supply in different areas is achieved through air deflector plates. There are also those with air outlets provided at both the top and bottom of the body, and no air outlet on the front of the body.

[0070] For a vertical air conditioner with a vertically arranged air outlet, the wind will blow directly at the front, which may cause the cold wind to blow directly and make the user feel uncomfortable. 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 wind in the front area of the body and the air supply distance is short.

[0071] The present utility model provides an air conditioner cabinet 100.

[0072] Please refer to Figures 1 to 19 , 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 duct 11 is provided inside the housing 10; the drainage component 20 is arranged on the air outlet side of the housing 10, and 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 a tuyere communicating with the duct 11; the switch door component 30 is arranged at the tuyere to open or cover the tuyere. The switch door component 30 includes an upper door body 31 and a lower door body 32. The upper door body 31 and the upper drainage member 21 can move relative to each other to form a first air outlet 111, the lower door body 32 and the lower drainage member 22 can move relative to each other to form a second air outlet 112, and the upper door body 31 and the lower door body 32 can move relative to each other to form a third air outlet 113; the wind wheel component 40 includes a first wind wheel component 41 and a second wind wheel component 42 arranged in the duct 11. The first wind wheel component 41 is arranged corresponding to the first air outlet 111, the second wind wheel component 42 is arranged corresponding to the second air outlet 112, and an air outlet channel corresponding to the third air outlet 113 is formed between the first wind wheel component 41 and the second wind wheel component 42.

[0073] 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 70 is further arranged in the air duct 11. The heat exchanger 70 can be arranged below the impeller 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 is 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 70 in the air duct 11, and then blows out air through the third air outlet 113, realizing the refrigeration or heating of the air conditioner cabinet 100.

[0074] When the air conditioner cabinet 100 is refrigerating, the upper door body 31 and the upper air guiding member 21 can move relative to each other, so that the first air outlet 111 between the upper air guiding member 21 and the upper door body 31 is opened. During the actual opening process of the first air outlet 111, it can be that the upper door body 31 moves away from the upper air guiding member 21 to open the first air outlet 111, or the upper air guiding member 21 moves away from the upper door body 31 to open the first air outlet 111, or the upper air guiding member 21 and the upper door body 31 move simultaneously to open the first air outlet 111. When the first impeller assembly 41 is working, 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 the density of cold air is relatively greater, when the mass of cold air is heavier than that of hot air, the cold air for long-distance air supply above the air conditioner cabinet 100 can sink, so that the cold air covers the entire space, avoiding discomfort caused by the cold air blowing directly on the human body.

[0075] When the air conditioner cabinet 100 is heating, the lower door body 32 and the lower air guiding member 32 can move relative to each other, so that the second air outlet 112 between the lower air guiding member 22 and the lower door body 32 is opened. During the actual opening process of the second air outlet 112, it can be that the lower door body 32 moves away from the lower air guiding member 22 to open the second air outlet 112, or the lower air guiding member 22 moves away from the lower door body 32 to open the second air outlet 112, or the lower air guiding member 22 and the lower door body 32 move simultaneously to open the second air outlet 112. When the second impeller assembly 42 is working, the hot air after heat exchange in the air duct 11 can be blown out from the second air outlet 112, realizing long-distance downward air supply. Since the density of hot air is relatively smaller, when the mass of hot air is lighter than that of cold air, the hot air for long-distance air supply below the air conditioner cabinet 100 is lighter in mass and 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 discomfort caused by the hot air blowing directly on the human body.

[0076] In addition, when the air conditioner cabinet 100 is cooling or heating, the upper door body 31 and the lower door body 32 that make up the switch door assembly 30 can move away from each other to open the third air outlet 113, and assist in cooling air outlet or heating air outlet through the third air outlet 113. A wind guiding structure can be arranged at the position of the third air outlet 113, so that in the cooling mode, the third air outlet 113 can blow air upward, and in the heating mode, the third air outlet 113 can blow air downward. While improving the air outlet coverage range through the third air outlet 113, it can avoid the air directly blowing on people.

[0077] Of course, 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 first wind wheel assembly 41 and the second wind wheel assembly 42 can work simultaneously, 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 113, making the air flow flowing out of the air conditioner cabinet 100 cover the upper space, the middle space, and the lower space, enabling the air flow after heat exchange inside the air conditioner cabinet 100 to be quickly blown out and cover the entire space, achieving the effect of full-speed cooling or full-speed heating.

[0078] The technical solution of the present utility model sets a drainage assembly 20 composed of an upper drainage member 21 and a lower drainage member 22, and a switch door assembly 30 composed of an upper door body 31 and a lower door body 32 on the air outlet side of the housing 10. The first air outlet 111 is formed by the relative movement and cooperation of the upper drainage member 21 and the upper door body 31, the second air outlet 112 is formed by the relative movement and cooperation of the lower drainage member 22 and the lower door body 32, and the third air outlet 113 is formed by the relative movement and cooperation of the upper door body 31 and the lower door body 32. When the first air outlet 111 is opened, the first wind wheel assembly 41 can guide the air after heat exchange in the air duct 11 to the first air outlet 111 and flow out from the first air outlet 111; when the second air outlet 112 is opened, the second wind wheel assembly 42 can guide the air after heat exchange in the air duct 11 to the second air outlet 112 and flow out from the second air outlet 112, so that the air flow after heat exchange in the air duct can flow out obliquely upward or obliquely downward, preventing the air outlet of the air conditioner cabinet 100 from directly blowing on people. Moreover, when the switch door assembly 30 opens the third air outlet 113, air can be blown out to the third air outlet 113 through the air outlet channel formed between the first wind wheel assembly 41 and the second wind wheel assembly 42. Cooperating with the first air outlet 111 and / or the second air outlet 112, the air supply coverage range can be improved, and the air supply experience of the air conditioner cabinet 100 during air outlet can be effectively improved.

[0079] Refer to Figure 5 、 Figure 7 、 Figure 8As shown, in the embodiment of the present utility model, 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;

[0080] When the upper air guiding member 21 is in the first position, the upper air guiding member 21 cooperates with the upper door body 31 to form the first air outlet 111, and a first acceleration flow channel 13 that communicates the first air outlet 111 with the air outlet end of the first air wheel assembly 41. When the upper air guiding member 21 is in the second position, the upper air guiding member 21 cooperates with the upper door body 31 to close the first air outlet 111; and / or

[0081] When the upper air guiding member 21 is in the first position, the upper door body 31 is used to open the third air outlet 113 upward.

[0082] In the above embodiment, the upper air guiding member 21 can be movably connected to the housing 10 through an 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 where it cooperates with the upper door body 31 to form the first air outlet 111, and a second position where it cooperates with the upper door body 31 to close the first air outlet 111.

[0083] 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 rotationally 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 away from its rotation, so that the upper air guiding member 21 can swing around the first rotating shaft. When the upper door body 31 is opened upward or the upper door body 31 is closed at the third air outlet 113, it can abut against the upper door body 31, so that it is in the second position where it cooperates with the upper door body 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 where it cooperates with the upper door body 31 to form the first air outlet 111.

[0084] Moreover, when the upper air guiding member 21 is in the first position, it can also cooperate with the upper door body 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.

[0085] When the upper air guide member 21 is in the first position to cooperate with the upper door body 31 to form the first air outlet 111 and the first acceleration flow channel 13, it can be realized not only by the movement of the upper air guide member 21, but also by the upward movement of the upper door body 31 to open the third air outlet 113. In this way, the third air outlet 113 can cooperate with the first air outlet 111 to open, thereby increasing the air supply coverage range of the air conditioner cabinet 100.

[0086] Continue to refer to Figure 5 、 Figure 7 、 Figure 8 As shown, in the embodiment of the present invention, when the upper air guide member 21 is in the first position, a first guiding surface 211 is formed on the surface of the upper air guide member 21 facing the upper door body 31, and the first guiding surface 211 extends obliquely upward from bottom to top toward the air outlet side of the housing 10; and / or

[0087] A first guiding portion 311 is provided on one side of the upper door body 31 facing the air duct 11, and the first guiding portion 311 is inclined downward from top to bottom toward the air outlet side of the housing 10.

[0088] With such a setting, when the upper air guide member 21 and the upper door body 31 enclose to form the first acceleration flow channel 13, the first guiding surface 211 serving as the upper side wall of the first acceleration flow channel 13 and the first guiding portion 311 serving as the lower side wall of the first acceleration flow channel 13 both extend obliquely upward from bottom to top toward the front end of the housing 10. In this way, 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, and the flow path of the air flow blown out from the first air outlet 111 can be set along a parabola, thereby realizing the requirement that the air flow flowing out from the first air outlet 111 can be blown out obliquely upward.

[0089] Continue to refer to Figure 5 、 Figure 7 、 Figure 8 In the embodiment of the present invention, a concave surface 2111 is formed by the portion of the first guiding surface 211 away from the upper door body 31 being recessed toward the inside of the housing 10.

[0090] Such a configuration can make the concave surface 2111 relatively farther from the extension line of the first guide portion 311. When the first guide surface 211 and the first guide portion 311 are enclosed to form the first accelerating channel 13, the shortest distance from the first guide surface 211 to the extension line of the first guide portion 311, from the input end of the first accelerating channel 13 to the output end of the first accelerating channel 13, presents a trend of gradually decreasing first and then gradually increasing. The first accelerating channel 13 presents a state of being narrow in the middle and wide at both ends. The first accelerating channel 13 is necked as a whole. The openings at both ends of the first accelerating channel 13 are large and slightly smaller in the middle. When air flows into the first accelerating channel 13, it can be accelerated through the narrower part in the middle. In this way, the blown airflow can be accelerated, thereby achieving air supply over a longer distance.

[0091] In addition, in other embodiments, a convex surface can be provided below the concave surface 2111 and located at the first guide surface 211, where the convex surface is relatively closer to the extension line of the first guide portion 311, thereby further making the first acceleration channel 13 have large openings at both ends and a slightly smaller opening in the middle, thereby enhancing the acceleration effect of the first acceleration channel 13.

[0092] See also Figure 8 As shown, in an embodiment of the present utility model, the angle between the tangent line of the upper end of the first guide surface 211 and the vertical direction is α, and the α is not less than 40 degrees and the α is not greater than 70 degrees.

[0093] In the present invention, the angle α between the upper tangent of the first guide surface 211 and the axial direction of the air conditioning cabinet 100 can be selected to be 40 degrees, 50 degrees, 60 degrees, 70 degrees, etc. In this embodiment, the angle α is 60 degrees.

[0094] Such a configuration can ensure that the angle of the air flow in the air duct 11 blowing out from the first air outlet 111 will not be too large or too small. When the first guide surface 211 has a concave surface 2111 and the first guide surface 211 is "S"-shaped as a whole, the flow path of the air flow blown out from the first air outlet 111 after being guided by the first guide surface 211 can be set in a parabolic shape. In this way, the air supply distance of the air-conditioning cabinet 100 through the first acceleration flow channel 13 can be further improved.

[0095] See also Figure 5 , Figure 7 , Figure 8 As shown, in an embodiment of the present invention, the flow cross-sectional area of ​​the first accelerating flow channel 13 is reduced from both ends of the first accelerating flow channel 13 to the middle of the first accelerating flow channel 13 .

[0096] It can be understood that the cross-sectional area of the first acceleration flow channel 13 may change in a stepped manner from both ends to the middle, or may be set to a more smooth tapered shape 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, it is not limited here.

[0097] With such a setting, when air passes through the first acceleration flow channel 13, the air flow can be accelerated through the relatively narrow position in the middle, thereby increasing the flow velocity of the air flow at the end of the first acceleration flow channel 13 and increasing the air outlet distance of the first air outlet 111.

[0098] Refer to Figure 4 、 Figure 5 、 Figure 8 As shown in, in the embodiment of the present invention, 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 channel 13, and the first cross-flow fan 413 is disposed in the first air passage 414.

[0099] Among them, the first volute 411 and the first volute tongue 412 may be inclined upward 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 upward 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 channel 13.

[0100] In the above embodiment, the cross-sections of the first volute 411 and the first volute tongue 412 may 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 may be in a spiral shape. In this way, 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 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 channel 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.

[0101] Refer to Figure 5 、 Figure 8 As shown in, in the embodiment of the present invention, the first volute tongue 412 and the first volute 411 are spaced apart from top to bottom. When the upper diversion member 21 is in the first position, the upper diversion member 21 abuts against the first volute tongue 412 to connect the first acceleration flow channel 13 and the first air passage 414.

[0102] 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 closely abutted. 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.

[0103] Continue to refer to Figure 5 、 Figure 8 As shown, in the embodiment of the present utility model, the first volute 411 and the upper door body 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.

[0104] 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 a spiral line and has a guiding effect, and due to the limitation of the upper door body 31, a first air guiding channel 15 is formed between the first volute 411 and the upper door body 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, and the air pressure of the first acceleration flow channel 13 can be increased. When the air can be accelerated in the first acceleration flow channel 13, the air flow blown out from the first air outlet 111 has a farther blowing distance.

[0105] Refer to Figure 5 、 Figure 9 、 Figure 10 As shown, in the embodiment of the present utility model, the lower air guiding member 22 is movably connected to the housing 10, and the lower air guiding member 22 has a third position and a fourth position;

[0106] When the lower air guiding member 22 is in the third position, the lower air guiding member 22 and the lower door body 32 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 outlet end of the second wind wheel assembly 42. When the lower air guiding member 22 is in the fourth position, the lower air guiding member 22 and the lower door body 32 cooperate to close the second air outlet 112; and / or

[0107] When the lower air guiding member 22 is in the third position, the lower door body 32 is used to open the third air outlet 113 downward.

[0108] In the above embodiments, the lower air guide member 22 can be movably connected to the housing 10 through the lower air guide driving member 24. The lower air guide driving member 24 is drivingly connected to the lower air guide member 22 so that the lower air guide member 22 has a third position that cooperates with the lower door body 32 to form the second air outlet 112, and a fourth position that cooperates with the lower door body 32 to close the second air outlet 112.

[0109] Among them, the lower air guide driving member 24 can be set as the lower driving motor 242 and the driving shaft rod 241. The lower air guide member 22 can be set as the lower air guide plate. A second rotating shaft 222 is arranged at a position of the lower air guide plate close to the lower edge of the air outlet, and it can be rotatably connected to the inner edge of the air outlet through the second rotating shaft 222. There are two sets of the lower driving motor 242 and the driving shaft rod 241. 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 guide 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 expand and contract by the lower driving motor 242, the lower air guide plate is pushed to swing around the second rotating shaft 222. When the lower door body 32 is opened downward or the lower door body 32 is closed at the third air outlet 113, the lower air guide member 22 can cooperate with the lower door body 32 to make it in the fourth position where it cooperates with the lower door body 32 to close the second air outlet 112, or the lower air guide member 22 can swing backward around the second rotating shaft 222 so that the upper end of the lower air guide plate abuts against the second volute tongue 422, and cooperate with the lower door body 32 to make it in the third position where it cooperates with the lower door body 32 to form the second air outlet 112.

[0110] Optionally, a connecting shaft 223 is arranged at the position where the lower air guide plate is connected to the driving shaft rod 241. The end of the driving shaft rod 241 is provided with a socket part 243 with a long strip-shaped slot. The lower air guide plate is sleeved and matched 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 guide member 22 to swing, it can provide a certain amount of movement allowance for the connection position between the lower air guide member 22 and the driving shaft rod 241.

[0111] In the above embodiments, the upper driving motor can be set as a stepping motor, which can servo-control the opening and closing angle of the upper air guide member 21 to make the movement of the upper air guide member 21 more accurate. The lower driving motor 242 can also be set as a stepping motor to servo-control the opening and closing angle of the lower air guide member 22 to ensure that the opening and closing movement of the lower air guide member 22 is more accurate.

[0112] Moreover, when the current air guiding member 22 is in the third position, it can also cooperate with the lower door body 32 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.

[0113] When the lower air guiding member 22 is in the third position to cooperate with the lower door body 32 to form the second air outlet 112 and the second acceleration flow channel 14, it can be realized not only through the movement of the lower air guiding member 22, but also through the movement of the lower door body 32 to open the third air outlet 113 downward. In this way, the third air outlet 113 can cooperate with the second air outlet 112 to open, thereby increasing the air supply coverage area of the air conditioner cabinet 100.

[0114] Continue to refer to Figure 5 、 Figure 9 、 Figure 10 As shown, in the embodiment of the present invention, when the lower air guiding member 22 is in the third position, a second guiding surface 221 is formed on the surface of the lower air guiding member 22 facing the lower door body 32, and the second guiding surface 221 extends obliquely downward from top to bottom towards the air outlet side of the housing 10; and / or

[0115] A second guiding portion 321 is provided on the side of the lower door body 32 facing the air duct 11, and the second guiding portion 321 extends obliquely downward from top to bottom towards the air outlet side of the housing 10.

[0116] In the above embodiment, similar to the cooperation between the upper air guiding member 21 and the upper door body 31, when the second acceleration flow channel 14 is formed by enclosing the lower air guiding member 22 and the lower door body 32, the second guiding surface 221 serving as the lower side wall of the second acceleration flow channel 14 and the second guiding portion 321 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 upper side wall and the lower 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, and 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 of the first air outlet 111 can be blown out obliquely downward.

[0117] Refer to Figure 9 As shown, in the embodiment of the present invention, the lower end of the second guiding surface 221 is bent upward to form a air supply extension portion 2211.

[0118] With such a setting, when air is guided out of the second air outlet 112 from the second acceleration flow channel 14 through the second guiding surface 221, the air supply extension part 2211 at the end of the second guiding surface 221 changes the air flow direction. Through the guidance of 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 towards the position closer to the air conditioner cabinet 100 on the ground, thereby achieving a longer air supply distance and preventing the air supply range of the air conditioner cabinet 100 through the second acceleration flow channel 14 from being affected.

[0119] 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 air 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 affecting the air supply distance.

[0120] Continue to refer to Figure 9 As shown, in the embodiment of the present invention, the included angle between the tangent line at 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.

[0121] In the above embodiment, 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.

[0122] 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.

[0123] Refer to Figure 5 、 Figure 9 、 Figure 10 As shown, in the embodiment of the present invention, the second air wheel 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 arranged in the second air passage 424.

[0124] 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 wind wheel 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 wind wheel assembly 42 is consistent with that of the second acceleration flow channel 14.

[0125] In the above embodiment, 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 passage 424, the air flow direction in the second air passage 424 can be spiral-shaped. In this way, when the air flow flows inside the second air passage 424, the flow resistance of the air flow in the second air passage 424 can be reduced, and since the second cross-flow fan 423 is provided in the second air passage 424, the air flow in the second air passage 424 can be further accelerated, so that the second acceleration flow channel 14 can accelerate and introduce the air flow through the second air passage 424, thereby ensuring the long-distance air supply effect of the second air outlet 112.

[0126] Continue to refer to Figure 5 、 Figure 9 、 Figure 10 In the embodiment of the present utility model, 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 passage 424;

[0127] 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.

[0128] With such a setting, when the second acceleration flow channel 14 is opened, the lower drainage member 22 can be lapped 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 passage 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 passage 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.

[0129] In addition, the change in the cross-sectional area of the second acceleration flow channel 14 can also adopt a manner similar to that of the first acceleration flow channel 13, that is, 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. In this way, the flowing gas in the second acceleration flow 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.

[0130] It can be understood that the change in the cross-sectional area of the second acceleration flow channel 14 from both ends to the middle can be a stepped reduction setting or a more smooth tapered setting from both ends to the middle, as long as the first acceleration flow channel 13 presents a structure that is wide at both ends and narrow in the middle, and no limitation is made here.

[0131] Continue to refer to Figure 5 、 Figure 9 、 Figure 10 In the embodiment of the present invention, the lower door body 32 and the second volute 421 cooperate to form a second drainage channel 16. When the lower drainage member 22 is in the third position, the second drainage channel 16 is used to direct the air flow in the air duct 11 to the second acceleration flow channel 14.

[0132] Similar to the function of the first drainage channel 15, due to the drainage 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 a spiral line, it has a drainage effect. And due to the limitation of the lower door body 32, a second drainage channel 16 is formed between the second volute 421 and the lower door body 32. Therefore, the air flowing downward along the outer wall of the second volute 421 is drained through the second drainage channel 16 and flows towards the second acceleration flow channel 14, thereby realizing an increase in the air volume of the second acceleration flow channel 14 and improving the air pressure of the second acceleration flow channel 14. When the second acceleration flow channel 14 can accelerate the air flow, the air flow blown out from the second acceleration flow channel 14 has a longer air supply distance.

[0133] Refer to Figure 5 、 Figure 6 、 Figure 10 As shown in

[0134] In the above embodiment, when the air conditioner cabinet 100 blows cold air through the first air outlet 111, with the third air outlet 113 opened by the switch door assembly 30, the air flow direction of the air blown out from the third air outlet 113 can be changed by the air guiding member 60, so that the air blows upward. While increasing the cold air supply range of the air conditioner cabinet 100, it can prevent the cold air blown out from the third air outlet 113 from directly blowing on the human body. At the same time, it can also make the blown cold air flow cover the indoor space from top to bottom, improving the refrigeration effect of the air conditioner cabinet 100.

[0135] When the air conditioner cabinet 100 blows hot air through the second air outlet 112, with the third air outlet 113 opened by the switch door assembly 30, the air flow direction of the air blown out from the third air outlet 113 can be changed by the air guiding member 60, so that the air blown out from the third air outlet 113 flows downward. While increasing the hot air supply range of the air conditioner cabinet 100, it can also prevent the hot air from directly blowing on the human body, and make the hot air cover the indoor space from bottom to top, improving the heating effect of the air conditioner cabinet 100.

[0136] Or, in other embodiments, when the first air outlet 111 and the second air outlet 112 are not opened, and the third air outlet 113 is opened by the switch door assembly 30 for air outlet, the air outlet direction of the third air outlet 113 can also be changed by the air guiding member 60 to prevent the air flow from directly blowing on the human body.

[0137] Refer to Figure 5 As shown, in the embodiment of the present utility model, the air guiding member 60 is provided with micropores;

[0138] And / or, the air guiding member 60 is arranged in a louver structure, including a plurality of swingable louvers 61.

[0139] Wherein, when the air guiding member 60 is arranged in a louver structure, the air guiding member 60 includes a plurality of louvers 61 arranged at intervals along the axial direction of the air conditioner cabinet 100 and a louver driving member 62 drivingly connected to the plurality of louvers 61;

[0140] The louver driving member 62 is used to drive the plurality of louvers 61 to rotate, so as to form a commutation flow channel for changing the air flow direction of the third air outlet 113 between adjacent louvers 61, or to connect the plurality of louvers 61 end to end to close the third air outlet 113.

[0141] In the above embodiments, the louver driving member 62 includes a link assembly and a rotational driving member. The rotational driving member can be set as a driving structure such as a stepper motor or a servo motor. A plurality of louvers 61 are connected by the link assembly. The link assembly is driven to swing by the rotational driving member, driving the plurality of louvers 61 to swing simultaneously, so as to change the direction of the louvers 61, and change the flow direction of the commutation flow channel formed between adjacent louvers 61, thereby realizing the change of the air outlet direction of the third air outlet 113.

[0142] In the above embodiments, when the air guiding member 60 is set as a louver structure, micropores can be formed on the louvers 61. With such a setting, in the state where the door opening and closing assembly 30 opens the third air outlet 113, when the plurality of louvers 61 are connected end to end to close the third air outlet 113, the third air outlet 113 discharges air through the micropores formed on the louvers 61, so that the air conditioner cabinet 100 can realize invisible air outlet through the micropores on the louvers 61.

[0143] Of course, in other embodiments, the air guiding member 60 may not include the louver driving member 62. A plurality of louvers 61 are connected by the link assembly. The swinging angle of the louvers 61 can be changed by manual adjustment, so as to form a commutation flow channel between adjacent louvers 61 and change the flow direction of the commutation flow channel.

[0144] Alternatively, in other embodiments, when the air guiding member 60 is a single movable air guiding plate, micropores can be formed on the air guiding plate. When the air guiding plate rotates to close the third air outlet 113, the third air outlet 113 discharges air through the micropores formed on the air guiding plate to realize invisible air outlet of the third air outlet 113.

[0145] Refer to Figure 14 、 Figure 15 As shown, in the embodiments of the present invention, the door opening and closing assembly 30 further includes a guiding assembly 33 and a door opening and closing driving member 34. The door opening and closing driving member 34 is used to drive the upper door body 31 and / or the lower door body 32 to move along the guiding assembly 33 to open and close the third air outlet 113.

[0146] In the above embodiments, the door opening and closing driving member 34 can be set as an upper door opening and closing driving member 341 and a lower door opening and closing driving member 342. The upper door body 31 and the lower door body 32 are respectively driven by the upper door opening and closing driving member 341 and the lower door opening and closing driving member 342 to move along the guiding assembly 33 to open and close the third air outlet 113. The activities of the upper door body 31 and the lower door body 32 can be independently controlled, or the upper door body 31 and the lower door body 32 can be opened and closed by a single door opening and closing driving member 34, and the upper door body 31 and the lower door body 32 are linked and controlled, which is not limited herein.

[0147] Continue to refer to Figure 14 、Figure 15 As shown, in the embodiment of the present utility model, the door opening and closing assembly 30 further includes a guiding assembly 33 and a door opening and closing driving member 34. The door opening and closing driving member 34 is used to drive the upper door body 31 and / or the lower door body 32 to move along the guiding assembly 33 to open and close the third air outlet 113;

[0148] When the upper door body 31 opens and closes the third air outlet 113, it can move while fitting the surface of the upper air guiding member 21 facing the air outlet side of the housing 10; and / or

[0149] When the lower air guiding member 22 opens and closes the third air outlet 113, it can move while fitting the surface of the lower air guiding member 22 facing the air outlet side of the housing 10.

[0150] In the above embodiment, the door opening and closing driving member 34 includes an upper door opening and closing driving member 341 and a lower door opening and closing driving member 342, and the guiding assembly 33 includes a first guiding member 331 and a second guiding member 332;

[0151] The upper door opening and closing driving member 341 is used to drive the upper door body 31 to move along the first guiding member 331, so that when the upper door body opens and closes the third air outlet 113, it can move while fitting the surface of the upper air guiding member 21 facing the air outlet side of the housing 10; and / or

[0152] The lower door opening and closing driving member 342 is used to drive the lower door body 32 to move along the second guiding member 332, so that when the lower door body 32 opens and closes the third air outlet 113, it can move while fitting the surface of the lower air guiding member 22 facing the air outlet side of the housing 10.

[0153] With such a setting, when the third air outlet 113 is opened and closed by the door opening and closing assembly 30, the upper door body 31 and the upper air guiding member 21 are always in a closed state, the first air outlet 111 will not be opened, and the lower door body 32 and the lower air guiding member 22 are also always in a closed state, and the second air outlet 112 will not be opened. In this way, the third air outlet 113 can be used for independent air outlet, or the third air outlet 113 can cooperate with one of the other two air outlets for air outlet, without causing air leakage at the unopened air outlet.

[0154] Continue to refer to Figure 14 、 Figure 15, in an embodiment of the present utility model, in a further embodiment, the first guide member 331 may include a first guide plate 3311 and a first drive rod 3312, and the upper door opening and closing drive member 341 may include an upper door drive motor 3411, a gear, and a rack bar 3412. A first guide groove 33111 and a second guide groove 33112 are formed on the outer side of the first guide plate 3311, and an activity chamber is formed inside the first guide plate 3311. The activity chamber communicates with the first guide groove 33111 and the second guide groove 33112. The upper door drive motor 3411 drives the gear to rotate. The gear is arranged on the first guide plate 3311, and the outer peripheral portion of the gear is accommodated in the activity chamber. The rack bar 3412 is arranged in the activity chamber, and the rack bar 3412 is in transmission connection with the gear.

[0155] A latch is installed at one end of the rack bar 3412. The latch penetrates through the activity chamber and is in guiding cooperation with the first guide groove 33111. The first drive rod 3312 is arranged on the outer side of the first guide plate 3311. A limiting shaft that is in guiding cooperation with the second guide groove 33112 is arranged at one end of the first drive rod 3312. The other end of the first drive rod 3312 is connected to the latch. The upper door drive motor 3411 drives the gear to rotate, driving the rack bar 3412 to move in the activity chamber. Since one end of the rack bar 3412 is connected to the first drive rod 3312 through the latch, and the latch is in guiding cooperation with the first guide groove 33111, the first drive rod 3312 can be driven to move, and is guided by the first guide groove 33111 and the second guide groove 33112.

[0156] First support ears 313 and second support ears 312 may be arranged on both sides of the upper door body 31. The first support ear 313 is connected to the first drive rod 3312. A third guide groove 17 may be arranged on the inner edge of the opening. The second support ear 312 may be in guiding cooperation with the third guide groove 17, enabling the upper door body 31 to be driven by the upper door drive motor 3411. Through the guiding cooperation between the first drive rod 3312 and the first guide plate 3311, and the guiding cooperation between the second support ear 312 and the third guide groove 17, the upper door body 31 can open or close the first and third air outlets 113 along a predetermined track. When the upper air guiding member 21 is not working, the upper door body 31 can always maintain a tight fit with the upper air guiding member 21 in both the door opening and closing states, preventing air leakage.

[0157] Among them, the upper door body 31 can move along a non-linear track. For this purpose, a long hole groove is arranged at the end of the rack bar 3412 connected to the latch. The latch is inserted into the long hole groove, and there can be a certain degree of freedom of movement in the long hole groove. When the first guide groove 33111 and the second guide groove 33112 are non-linear grooves, it can ensure that the first drive rod 3312 can be guided without interference.

[0158] It can be understood that since the upper door body 31 and the lower door body 32 can be arranged in a vertically mirror-symmetrical manner, the second guiding member 332 and the lower door opening and closing driving member 342 can be arranged in a mirror-symmetrical manner with respect to the first guiding member 331 and the upper door opening and closing driving member 341, which will not be elaborated herein.

[0159] Refer to Figure 1 、 Figure 10 、 Figure 12 As shown in the figures, in an embodiment of the present invention, the air-conditioning cabinet machine further includes a draft fan 50 and a heat exchanger 70 disposed in the air duct 11. The housing 10 has an air inlet 12 communicating with the air duct 11. The draft fan 50 is disposed between the air inlet 12 and the heat exchanger 70, and the air wheel assembly 40 is disposed between the heat exchanger 70 and the air outlet.

[0160] In the above embodiment, the draft fan 50 can be disposed below the heat exchanger 70 for introducing external air from the air inlet 12 into the air duct 11. By setting the 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 air wheel assembly 41 and the second air wheel assembly 42 are working, there is sufficient air intake. At the same time, the draft fan 50 can assist the air outlet of the first air outlet 111 and the second air outlet 112 to speed up the air flow in the first acceleration flow channel 13 and the second acceleration flow channel 14.

[0161] Moreover, since the draft fan 50 is provided and 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 113, so that the third air outlet 113 can also assist in air outlet.

[0162] Continue to refer to Figure 4 、 Figure 7 In the present invention, the heat exchanger 70 includes a first heat exchange portion and a second heat exchange portion connected to each other. A connection included angle is formed between the first heat exchange portion and the second heat exchange portion, and the connection included angle is an acute angle.

[0163] With such a setting, when the draft fan 50 is drawing in air, the contact area between the heat exchanger 70 and the incoming air can be increased, thereby improving the heat exchange effect. When the present invention can achieve long-distance inclined air supply in the upper part, normal air supply in the middle part, and long-distance inclined air supply in the lower part, the air-conditioning cabinet machine 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-conditioning cabinet machine 100.

[0164] In the above embodiments, the connection part between 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, which is arranged between the heat exchanger 70 and the induced draft fan 50, and the connection part between the first heat exchange part and the second heat exchange part is arranged in the water receiving tray.

[0165] With such an arrangement, the condensed water generated by the heat exchanger 70 during heat exchange can flow down along the heat exchanger 70 into the water receiving tray, 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.

[0166] Refer to Figure 7 、 Figure 9 、 Figure 11 As shown in

[0167] In the embodiments of the present invention, the air conditioner cabinet has a first cooling mode and a second cooling mode. When the air conditioner cabinet is in the first cooling mode, the air conditioner cabinet blows air from the first air outlet 111 and the third air outlet 113. When the air conditioner cabinet is in the second cooling mode, the air conditioner cabinet blows air from the first air outlet 111, the second air outlet 112, and the third air outlet 113; and / or

[0167] The air conditioner cabinet has a heating mode. When the air conditioner cabinet is in the heating mode, the air conditioner cabinet blows air from the second air outlet 112 and the third air outlet 113.

[0168] 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 113. The air guiding member 60 at the third air outlet 113 can be opened obliquely upward to realize long-distance air supply obliquely upward, avoiding direct blowing on the human body; 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 113. The air guiding member 60 at the third air outlet 113 is opened flatly, and the air conditioner cabinet 100 operates in the full-speed cooling mode to realize large-volume air supply.

[0169] 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 and the third air outlet 113 are opened, and the air guiding member 60 located in the air duct 11 is opened obliquely downward to realize long-distance air supply obliquely downward. 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.

[0170] In addition, in other embodiments, the air conditioner cabinet 100 may further have a full-speed heating mode. At this time, the first air outlet 111, the second air outlet 112, and the third air outlet 113 are all opened, and the first impeller assembly 41, the second impeller assembly 42, and the induced draft fan 50 all operate, so that the hot air in the air duct 11 can be quickly discharged to the room.
