[0066] For existing vertical air conditioners, some have vertically arranged air outlets, and the air supply to different areas is achieved through air deflectors. 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.

[0067] For a vertical air conditioner with a vertically arranged air outlet, the air 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.

[0068] The present utility model provides an air conditioner cabinet 100.

[0069] Please refer to Figures 1 to 16 , in an embodiment of the present utility model, the air conditioner cabinet 100 includes:

[0070] A housing 10, within which an air duct 11 is provided;

[0071] A drainage assembly 20, provided on the air outlet side of the housing 10. The drainage assembly 20 includes an upper drainage member 21 and a lower drainage member 22 that are spaced apart vertically. The upper drainage member 21 and the lower drainage member 22 enclose an air outlet that communicates with the air duct 11;

[0072] A switch door assembly 30, provided at the air outlet to open or cover the air outlet. The switch door assembly 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 switch door assembly 30 cooperates with the drainage assembly 20 to selectively open at least one of the first air outlet 111, the second air outlet 112, and the third air outlet 113; and

[0073] An air guiding assembly is arranged in the air duct 11 and is used for guiding the air flow inside the air duct 11 to flow towards the air outlet.

[0074] 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.

[0075] In the present utility model, the housing 10 is further provided with an air inlet 12 which is communicated with the air duct 11. 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, or air inlets 12 are arranged both below the side and below the back of the housing 10. A heat exchanger 80 is further arranged in the air duct 11. The heat exchanger 80 can be arranged below the air guiding assembly. In this way, the air duct 11 takes in air through the air inlet 12, exchanges heat with the heat exchanger 80 in the air duct 11, and then blows out air through the third air outlet 113, so as to realize the refrigeration or heating of the air conditioner cabinet 100.

[0076] 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. Through the operation of the air guiding assembly, the air flow inside the air duct 11 is guided to flow towards the first air outlet 111, and the cooled air after heat exchange inside the air duct 11 can be blown out from the first air outlet 111, so as to realize long-distance upward air supply. Since the density of cold air is greater than that of hot air, and the weight of the same volume of cold air is greater, 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 direct blowing of cold air on the human body.

[0077] When the air conditioner cabinet 100 is heating, the lower air deflector 22 and the lower door body 32 can move relative to each other, opening the second air outlet 112 between the lower air deflector 22 and the lower door body 32. 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 deflector 22 to open the second air outlet 112, or the lower air deflector 22 moves away from the lower door body 32 to open the second air outlet 112, or the lower air deflector 22 and the lower door body 32 move simultaneously to open the second air outlet 112. Through the operation of the air guiding component, the airflow inside the air duct 11 is guided to flow towards the second air outlet 112, and 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 the density of hot air is smaller than that of cold air, and the weight of the same volume of hot air is smaller, 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, enabling the hot air to cover the entire space from bottom to top and avoiding the discomfort caused by the hot air blowing directly on the human body.

[0078] In addition, when the air conditioner cabinet 100 is cooling and 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 the third air outlet 113 is used to assist in cooling air discharge or heating air discharge. And a wind guiding structure can be set at the position of the third air outlet 113, so that in the cooling mode, the third air outlet 113 can blow air upwards, and in the heating mode, the third air outlet 113 can blow air downwards. While increasing the air discharge coverage range through the third air outlet 113, it can avoid the air blowing directly on the human body.

[0079] 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. Through the operation of the air guiding component, the airflow inside the air duct 11 is guided to flow towards the first air outlet 111, the second air outlet 112, and the third air outlet 113, 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, enabling the airflow flowing out of the air conditioner cabinet 100 to cover the upper space, the middle space, and the lower space, and enabling the airflow 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.

[0080] The technical solution of the present utility model provides a diversion assembly 20 composed of an upper diversion member 21 and a lower diversion member 22 at the air outlet of the housing 10, and a door opening and closing assembly 30 composed of an upper door body 31 and a lower door body 32. Through the relative movement and cooperation of the upper diversion member 21 and the upper door body 31, a first air outlet 111 is formed. Through the relative movement and cooperation of the lower diversion member 22 and the lower door body 32, a second air outlet 112 is formed. And through the relative movement and cooperation of the upper door body 31 and the lower door body 32, a third air outlet 113 is formed. The door opening and closing assembly 30 cooperates with the diversion assembly 20 to selectively open at least one of the first air outlet 111, the second air outlet 112, and the third air outlet 113;

[0081] Since the air flow inside the air duct 11 can be guided by the air guiding assembly towards the air outlet, when the first air outlet 111 is opened, the heat-exchanged air in the air duct 11 can be guided to the first air outlet 111 and flow out from the first air outlet 111; when the second air outlet 112 is opened, the heat-exchanged air in the air duct 11 can be guided to the second air outlet 112 and flow out from the second air outlet 112, enabling the heat-exchanged air flow in the air duct to be inclined upwards or downwards, which can prevent the air blown out by the air conditioner cabinet 100 from directly hitting the human body; and when the third air outlet 113 is opened, the heat-exchanged air in the air duct 11 can be guided to the third air outlet 113 and flow out from the third air outlet 113. 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 when blowing air can be effectively enhanced.

[0082] Refer to Figure 4 、 Figure 5 As shown, in the embodiment of the present utility model, the air guiding assembly includes an air duct volute assembly 40 and a wind wheel assembly 50. The air duct volute assembly 40 is used to guide the air flow in the air duct 11 to flow out from the first air outlet 111, and the wind wheel assembly 50 is used to guide the air flow in the air duct 11 to flow out from the second air outlet 112.

[0083] With such a setting, the air flow direction inside the air duct 11 can be guided, enabling the first air outlet 111 and the second air outlet 112 to introduce the air flow inside the air duct 11 and achieve precise air outlet.

[0084] Of course, in other embodiments, the air guiding assembly may also include a first wind wheel assembly and a second wind wheel assembly. The first wind wheel assembly is arranged corresponding to the first air outlet 111, and the second wind wheel assembly is arranged corresponding to the second air outlet 112 to respectively guide the air flow inside the air duct 11 to the first air outlet 111 and the second air outlet 112.

[0085] Alternatively, in another embodiment, the air guiding assembly may further include a first air duct volute assembly and a second air duct volute assembly. The first air duct volute assembly is disposed corresponding to the first air outlet 111, and the second air duct volute is disposed corresponding to the second air outlet 112, so as to direct the airflow inside the air duct 11 to the first air outlet 111 and the second air outlet 112 respectively.

[0086] Refer to Figure 5 、 Figure 6 、 Figure 8 As shown, in the embodiment of the present utility model, the upper drainage member 21 is movably connected to the housing 10, and the upper drainage member 21 has a first position and a second position;

[0087] When the upper drainage member 21 is in the first position, the upper drainage member 21 and the upper door body 31 cooperate 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 air duct volute assembly 40. When the upper drainage member 21 is in the second position, the upper drainage member 21 and the upper door body 31 cooperate to close the first air outlet 111; and / or

[0088] When the upper drainage member 21 is in the first position, the upper door body 31 is used to open the third air outlet 113 upward.

[0089] In the above embodiment, the upper drainage member 21 can be movably connected to the housing 10 through an upper drainage driving member 23. The upper drainage driving member 23 is drivingly connected to the upper drainage member 21, so that the upper drainage member 21 has a first position that cooperates with the upper door body 31 to form the first air outlet 111, and a second position that cooperates with the upper door body 31 to close the first air outlet 111.

[0090] Among them, the upper drainage driving member 23 can be set as an upper driving motor and a connecting rod assembly. The upper drainage member 21 can be set as an upper drainage plate. The position of the upper drainage 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 drainage member 21 far from its rotation, so that the upper drainage 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 that cooperates with the upper door body 31 to close the first air outlet 111, or the upper drainage member 21 can swing backward around the rotating shaft, so that it is in the first position that cooperates with the upper door body 31 to form the first air outlet 111.

[0091] 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 air duct 13 connecting the first air outlet 111, so that the air flowing out from 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.

[0092] When the upper air guiding 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 air duct 13, it can be achieved not only through the movement of the upper air guiding member 21, but also through 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.

[0093] Continue to refer to Figure 5 、 Figure 6 、 Figure 8 As shown, in the embodiment of the present invention, when the upper air guiding member 21 is in the first position, a first guiding surface 211 is formed on the surface of the upper air guiding member 21 facing the upper door body 31, and the first guiding surface 211 extends obliquely upward from bottom to top towards the air outlet side of the housing 10; and / or

[0094] A first guiding portion 311 is provided on the 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 towards the air outlet side of the housing 10.

[0095] With such a setting, when the first acceleration air duct 13 is formed by enclosing the upper air guiding member 21 and the upper door body 31, both the first guiding surface 211 serving as the upper side wall of the first acceleration air duct 13 and the first guiding portion 311 serving as the lower side wall of the first acceleration air duct 13 extend obliquely upward from bottom to top towards the air outlet end of the housing 10. In this way, both the upper side wall and the lower side wall of the first acceleration air duct 13 can guide the air flow in the first acceleration air duct 13, so that the first acceleration air duct 13 blows air obliquely upward towards 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.

[0096] Refer to Figure 8 As shown, 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 towards the inside of the housing 10.

[0097] With such a setting, the concave surface 2111 can be relatively farther away from the extension line of the first guiding part 311. When the first guiding surface 211 and the first guiding part 311 enclose the first accelerating flow channel 13, the shortest distance from the first guiding surface 211 to the extension line of the first guiding part 311 gradually decreases first and then gradually increases from the input end to the output end of the first accelerating flow channel 13. The first accelerating flow channel 13 is in a state of being narrow in the middle and wide at both ends, and the whole of the first accelerating flow channel 13 is in a constricted neck shape. The openings at both ends of the first accelerating flow channel 13 are large, and the middle position is slightly smaller. When air flows into the first accelerating 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 part 311, so that the first accelerating flow channel 13 can be further in a state of having large openings at both ends and a slightly smaller middle position, and the accelerating effect of the first accelerating flow channel 13 can be improved.

[0099] Refer to Figure 8 As shown, in the embodiment of the present invention, the included angle between the tangent line at the upper end of the first guiding surface 211 and the vertical direction is α, and α is not less than 40 degrees and not greater than 70 degrees.

[0100] In the present invention, the included angle α between the tangent line at the upper end of the first guiding surface 211 and the vertical direction can be selected as 40 degrees, 50 degrees, 60 degrees, 70 degrees, etc. In this embodiment, the included angle α is selected as 60 degrees.

[0101] 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 is in a parabolic shape. In this way, the air supply distance of the air conditioner cabinet 100 through the first accelerating flow channel 13 can be further improved.

[0102] Refer to Figure 8 As shown, in the embodiment of the present invention, the cross-sectional area of the first accelerating flow channel 13 is arranged to decrease from both ends of the first accelerating flow channel 13 to the middle of the first accelerating flow channel 13.

[0103] It can be understood that the change of the cross-sectional area of the first accelerating flow channel 13 from both ends to the middle can be a stepped decrease setting or a more smooth tapered setting from both ends to the middle, as long as the first accelerating flow channel 13 has a structure of being wide at both ends and narrow in the middle, and no limitation is made here.

[0104] With such a setting, when air passes through the first acceleration flow channel 13, 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.

[0105] Refer to Figure 5 、 Figure 6 、 Figure 8 As shown in , in an embodiment of the present invention, the air duct volute assembly 40 includes a first air duct volute 41, and the first air duct volute 41 extends obliquely upward toward the air outlet side of the housing 10. When the upper diversion member 21 is in the first position, the upper diversion member 21 is in abutting cooperation with the first air duct volute 41.

[0106] Among them, the cross-sectional shape of the first air duct volute 41 can be a spiral shape. The first air duct volute 41 can be used as a part of the outer housing of the air duct volute assembly 40. The first air duct volute 41 extends obliquely upward toward the air outlet end of the housing 10. With such a setting, when guiding the air flow into the first acceleration flow channel 13 through the first air duct volute 41, the overall flow direction of the air flow will not change, thereby not affecting the flow velocity of the air flow. In addition, when forming the first acceleration flow channel 13, the upper diversion member 21 is in abutting cooperation with the first air duct volute 41, so that there is no gap or a small gap at the connection position between the first acceleration flow channel 13 and the air duct volute assembly 40, thereby avoiding the leakage of the air flow flowing from the air duct volute assembly 40 to the first acceleration flow channel 13. Moreover, the upper diversion member 21 is in abutting cooperation with the first air duct volute 41, which can also provide positioning for the movement of the upper diversion member 21 away from the upper door body 31, so that the upper diversion member 21 can always move to the defined position when forming the first acceleration flow channel 13, thereby ensuring the stability of the formed first acceleration flow channel 13.

[0107] Refer to Figure 8 As shown in , in an embodiment of the present invention, the air duct volute assembly 40 further includes a second air duct volute 42. The second air duct volute 42 is disposed on one side of the first air duct volute 41 close to the air outlet. The second air duct volute 42 extends obliquely upward toward the air outlet side of the housing 10. The second air duct volute 42 and the first air duct volute 41 enclose a first air passing duct 43, and the first air passing duct 43 is used to guide the air flow in the air duct 11 to the first acceleration flow channel 13.

[0108] With such a setting, the first air passage 43 can be defined by the second air passage volute 42 and the first air passage volute 41. When guiding the internal air flow of the air passage 11 through the first air passage volute 41, since the second air passage volute 42 also extends obliquely upward toward the air outlet end of the housing 10, the second air passage volute 42 can also guide the internal air flow of the air passage 11, thereby ensuring the flow direction of the overall air flow in the first air passage 43 and realizing guiding the heat-exchanged air flow inside the air passage 11 to the first acceleration flow passage 13.

[0109] In the above embodiment, the cross-sectional shape of the second air passage volute 42 can also be a spiral shape extending toward the front end of the housing 10. In this way, it can cooperate with the first air passage volute 41 with a spiral cross-section, reduce the wind resistance encountered by the air flow in the first air passage 43, and thus reduce the loss of wind pressure and air volume.

[0110] Of course, in other embodiments of the present invention, the cross-section of the second air passage volute 42 may not be set as a spiral shape, for example, it can be an inclined straight line shape, and the first air passage volute 41 can be set in the same way, which is not limited herein.

[0111] Continue to refer to Figure 8 As shown, in the embodiment of the present invention, the second air passage volute 42 and the upper door body 31 enclose a first diversion channel 15. When the upper diversion member 21 is in the first position, the first diversion channel 15 is used to guide the air flow in the air passage 11 to the first acceleration flow passage 13.

[0112] Since the air passage volute assembly 40 is located inside the air passage 11 and the switch door assembly 30 is located at the air outlet, the second air passage volute 42 of the air passage volute assembly 40 is located on the side of the upper door body 31 facing the air passage 11. And because the second air passage volute 42 is arranged to be inclined upward toward the air outlet end of the housing 10, the second air passage volute 42 can enclose a first diversion channel 15 with the upper door body 31. When the air passage volute assembly 40 diverts air to the first acceleration flow passage 13, the first diversion channel 15 on one side of the air passage volute assembly 40 will also divert air to the first acceleration flow passage 13, increasing the air intake volume for the first acceleration flow passage 13, thereby increasing the wind pressure of the first acceleration flow passage 13 and enabling the first air outlet 111 to achieve a farther air supply distance.

[0113] Refer to Figure 6 、 Figure 7 As shown, in the embodiment of the present invention, the second air passage volute 42 and the wind wheel assembly 50 enclose an air outlet passage corresponding to the third air outlet 113, and the air outlet passage is arranged to expand toward the third air outlet 113.

[0114] With such a setting, inside the air duct 11, an air outlet duct is defined by the outer shell of the air wheel assembly 50 and the second air duct volute 42. When air is discharged from the third air outlet 113, the air flow inside the air duct 11 can flow along a specified direction, thereby facilitating the discharge of air from the third air outlet 113.

[0115] Refer to Figure 5 、 Figure 10 As shown, in an embodiment of the present invention, the air guiding assembly further includes a guiding member 70 movably disposed in the air outlet duct. The guiding member 70 is used to change the air flow direction of the third air outlet 113 or to close the third air outlet 113.

[0116] In the above embodiment, when the air conditioner cabinet 100 discharges cold air through the first air outlet 111 and the third air outlet 113 is opened by the switch door assembly 30, the guiding member 70 can change the air flow direction of the air blown out from the third air outlet 113 in the air outlet duct, 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.

[0117] When the air conditioner cabinet 100 discharges hot air through the second air outlet 112 and the third air outlet 113 is opened by the switch door assembly 30, the guiding member 70 can change the air flow direction of the air blown out from the third air outlet 113 in the air outlet duct, 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.

[0118] Alternatively, 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 discharge, the guiding member 70 can also change the air outlet direction of the third air outlet 113 to prevent the air flow from directly blowing on the human body.

[0119] Continue to refer to Figure 5 、 Figure 10 As shown, in an embodiment of the present invention, the guiding member 70 is provided with micropores; and / or the guiding member 70 is arranged in a louver structure, including a plurality of swingable louvers 71.

[0120] Among them, when the guiding member 70 is arranged in a louver structure, the guiding member 70 includes a plurality of louvers 71 arranged at intervals in the vertical direction and a louver driving member 72 drivingly connected to the plurality of louvers 71;

[0121] The louver driving member 72 is used to drive a plurality of the louvers 71 to rotate, so as to form a commutation flow channel between adjacent louvers 71 for changing the air flow direction of the third air outlet 113, or to connect the plurality of louvers 71 end to end to close the third air outlet 113.

[0122] In the above embodiment, the louver driving member 72 includes a link assembly and a rotation driving member. The rotation driving member can be set as a driving structure such as a stepper motor or a servo motor. A plurality of louvers 71 are connected by the link assembly. By driving the link assembly to swing through the rotation driving member, a plurality of louvers 71 are driven to swing simultaneously, so that the direction of the louvers 71 is changed, and the flow direction of the commutation flow channel formed between adjacent louvers 71 is changed, thereby realizing the change of the air outlet direction of the third air outlet 113.

[0123] In the above embodiment, when the air guiding member 70 is set as a louver structure, micropores can be opened on the louvers 71. With such a setting, in the state where the door opening and closing assembly 30 opens the third air outlet 113, when a plurality of louvers 71 are connected end to end to close the third air outlet 113, the third air outlet 113 blows air through the micropores opened on the louvers 71, so that the air conditioner cabinet 100 can realize invisible air outlet through the micropores on the louvers 71.

[0124] Of course, in another embodiment, the air guiding member 70 may not include the louver driving member 72. A plurality of louvers 71 are connected by a link assembly, and the swinging angle of the louvers 71 can be changed by manual adjustment, so as to form a commutation flow channel between adjacent louvers 71 and change the flow direction of the commutation flow channel.

[0125] Or, in another embodiment, when the guiding member is a single movable air guiding plate, micropores can be opened on the air guiding plate. When the air guiding plate rotates to close the third air outlet 113, the third air outlet 113 blows air through the micropores opened on the air guiding plate to realize invisible air outlet of the third air outlet 113.

[0126] Refer to Figure 4 、 Figure 9 、 Figure 10 As shown, in the embodiment of the present invention, 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;

[0127] 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 the second acceleration flow channel 14 connecting the second air outlet 112 and the air outlet end of the air wheel assembly 50. 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

[0128] When the lower drainage member 22 is in the third position, the lower door body 32 is used to open the third air outlet 113 downward.

[0129] In the above embodiment, the lower drainage member 22 can be movably connected to the housing 10 through a lower drainage driving member 24. The lower drainage driving member 24 is drivingly connected to the lower drainage member 22, so that the lower drainage member 22 has a third position in which it cooperates with the lower door body 32 to form the second air outlet 112, and a fourth position in which it cooperates with the lower door body 32 to close the second and third air outlets 113.

[0130] Among them, the lower drainage driving member 24 can be set as a lower driving motor 242 and a driving shaft rod 241. The lower drainage member 22 can be set as a lower drainage plate. A second rotating shaft 222 is arranged at a position of the lower drainage plate close to the lower edge of the air outlet, and it can be rotationally 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, 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 drainage 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 drainage 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 drainage 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 drainage member 22 can swing backward around the second rotating shaft 222, so that the upper end of the lower drainage plate abuts against the air wheel volute 52, and cooperates 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.

[0131] Optionally, a connecting shaft 223 is arranged at the position where the lower drainage 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 hole. The lower drainage 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 drainage member 22 to swing, it can provide a certain amount of movement margin for the connection position between the lower drainage member 22 and the driving shaft rod 241.

[0132] In the above embodiment, 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 drainage member 21, making the action of the upper drainage member 21 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 drainage member 22, ensuring that the opening and closing action of the lower drainage member 22 is more accurate.

[0133] Moreover, when the current air guide 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.

[0134] When the lower air guide 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 guide 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 range of the air conditioner cabinet 100.

[0135] Continue to refer to Figure 4 、 Figure 9 、 Figure 10 In the embodiment of the present invention, when the lower air guide member 22 is in the third position, a second guiding surface 221 is formed on the surface of the lower air guide member 22 facing the lower door body 32, and the second guiding surface 221 extends obliquely downward from top to bottom toward the air outlet side of the housing 10; and / or

[0136] 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 toward the air outlet side of the housing 10.

[0137] In the above embodiment, similar to the cooperation between the upper air guide member 21 and the upper door body 31, when the second acceleration flow channel 14 is formed by enclosing the lower air guide member 22 and the lower door body 32, both 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 extend obliquely downward from top to bottom toward 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 toward the second air outlet 112, and the air flow 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.

[0138] 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 blowing extension portion 2211.

[0139] 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 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 through the second acceleration flow channel 14.

[0140] 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 part 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 the influence on the air supply distance.

[0141] Continue to refer to Figure 9 As shown, in the embodiment of the present utility model, the included angle between the tangent line at the lower end of the second guiding surface 221 and the vertical direction is β, and β is not less than 10 degrees and not greater than 45 degrees.

[0142] 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.

[0143] 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.

[0144] Refer to Figure 9 、 Figure 10 As shown, in the embodiment of the present utility model, the impeller assembly 50 includes an impeller volute 51, an impeller volute tongue 52 and a cross-flow impeller 53. The impeller volute 51 and the impeller volute tongue 52 enclose a second air passing air duct 54 for communicating with the second acceleration flow channel 14, and the cross-flow impeller 53 is arranged in the second air passing air duct 54.

[0145] In the above embodiments, the cross-sections of the wind wheel volute 51 and the wind wheel volute tongue 52 can both be spiral-shaped. When the wind wheel volute 51 and the wind wheel volute tongue 52 enclose to form the second air passage 54, the air flow direction in the second air passage 54 can be spiral-shaped. In this way, when the air flow flows inside the second air passage 54, the flow resistance of the air flow in the second air passage 54 can be reduced. And since the cross-flow fan 53 is arranged in the second air passage 54, the air flow in the second air passage 54 can be further accelerated, so that the second acceleration flow channel 14 can accelerate and introduce the air flow through the second air passage 54, thereby ensuring the long-distance air supply effect of the second air outlet 112.

[0146] Continue to refer to Figure 9 、 Figure 10 In the embodiment of the present utility model, the wind wheel volute 51 and the wind wheel volute tongue 52 are arranged at intervals from top to bottom. When the lower drainage member 22 is in the third position, the wind wheel volute tongue 52 is in abutting cooperation with the lower drainage member 22, so that the second acceleration flow channel 14 is connected to the second air passage 54;

[0147] And / or, the cross-sectional area of the second acceleration flow channel 14 is arranged to decrease from both ends of the second acceleration flow channel 14 towards the middle of the second acceleration flow channel 14.

[0148] It can be understood that since the switch door assembly 30 is located at the air outlet and the wind wheel assembly 50 is located inside the air duct, the wind wheel volute 51 is located on the side of the lower door body 32 facing the air duct 11. When the lower drainage member 22 is in the third position and the wind wheel volute tongue 52 is in abutting cooperation with the lower drainage member 22, the wind wheel volute 51 is located above the lower drainage member 22. The air flow flowing out from the second air passage 54 will directly flow into the second acceleration flow channel 14 under the guidance of the cross-flow fan 53 and the air flow direction of the second air passage 54. Since the lower drainage member 22 and the wind wheel volute tongue 52 that form the second acceleration flow channel 14 are in abutting contact, there may be no gap or the gap is small between them. Therefore, when the second air passage 54 blows air towards the second acceleration flow channel 14, air leakage can be reduced or avoided, thereby ensuring the air intake volume of the second acceleration flow channel 14.

[0149] In addition, the change in the cross-sectional area of the second acceleration flow channel 14 can also adopt a similar method to that of the first acceleration flow channel 13, that is, the cross-sectional area of the second acceleration flow channel 14 is arranged to decrease from both ends of the second acceleration flow channel 14 towards the middle of the second acceleration flow channel 14. In this way, the flowing air in the second acceleration flow channel 14 can be accelerated through the narrower part, so that the air flow blown out from the second and third air outlets 113 can also achieve a longer-distance air supply.

[0150] 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 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 flow channel 13 has a structure that is wide at both ends and narrow in the middle, it is not limited here.

[0151] Continue to refer to Figure 9 、 Figure 10 In the embodiment of the present utility model, the wind wheel volute 51 and the upper door body 31 enclose 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 airflow in the air duct 11 to the second acceleration flow channel 14.

[0152] Similar to the function of the first drainage channel 15, due to the drainage effect of the cross-flow fan 53, the air inside the air duct 11 flows towards the direction of the cross-flow fan 53. When the air flows downward from the wind wheel volute 51, since the outer shape of the wind wheel volute 51 can be a spiral curve, 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 wind wheel volute 51 and the lower door body 32. Therefore, the air flowing downward along the outer wall of the wind wheel volute 51 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 to a certain extent, and the air pressure of the second acceleration flow channel 14 can be improved. When the second acceleration flow channel 14 can accelerate the flow of air, the airflow blown out from the second acceleration flow channel 14 has a farther blowing distance.

[0153] Refer to Figure 14 、 Figure 15 As shown in

[0154] In the above embodiment, the switch door driving member 34 can be set as an upper switch door driving member 341 and a lower switch door driving member 342. The upper switch door driving member 341 and the lower switch door driving member 342 respectively drive the upper door body 31 and the lower door body 32 to move along the guiding component 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 opening and closing of the upper door body 31 and the lower door body 32 can be controlled by a single switch door driving member 34, and the upper door body 31 and the lower door body 32 are controlled in a linkage manner, which is not limited here.

[0155] Continue to refer to Figure 14 、 Figure 15, in an 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 configured 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;

[0156] When the upper door body 31 opens and closes the third air outlet 113, it can move along the side of the upper air guiding member 21 facing the air outlet side of the housing 10; and / or

[0157] When the lower air guiding member 22 opens and closes the third air outlet 113, it can move along the side of the lower air guiding member 22 facing the air outlet side of the housing 10.

[0158] 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;

[0159] The upper door opening and closing driving member 341 is configured to drive the upper door body 31 to move along the first guiding member 331, so that when the upper door body 31 opens and closes the third air outlet 113, it can move along the side of the upper air guiding member 21 facing the air outlet side of the housing 10; and / or

[0160] The lower door opening and closing driving member 342 is configured 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 along the side of the lower air guiding member 22 facing the air outlet side of the housing 10.

[0161] 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 blow air alone, or cooperate with one of the other two air outlets to blow air, without causing air leakage at the unopened air outlet.

[0162] 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 a movable chamber is formed inside the first guide plate 3311. The movable 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 movable chamber. The rack bar 3412 is arranged in the movable chamber, and the rack bar 3412 is in transmission connection with the gear.

[0163] A latch is installed at one end of the rack bar 3412. The latch passes through the movable chamber and is in guiding cooperation with the first guide groove 33111. The first drive rod 3312 is arranged outside the first guide plate 3311. A limit shaft that is in guiding cooperation with the second guide groove 33112 is provided 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 movable 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.

[0164] Both sides of the upper door body 31 may be provided with a first support ear 313 and a second support ear 312. The first support ear 313 is connected to the first drive rod 3312. A third guide groove 17 may be provided along 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 flow guiding member 21 is not working, the upper door body 31 can always maintain a tight fit with the upper flow guiding member 21 in the door opening and closing states, preventing air leakage.

[0165] Among them, the upper door body 31 can move along a non-linear track. For this purpose, a long hole groove is provided 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.

[0166] 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 here.

[0167] Refer to Figure 4 、 Figure 6 、 Figure 7 As shown in

[0168] In the above embodiment, the induced draft fan 60 can be arranged below the heat exchanger 80 for introducing external air from the air inlet 12 into the air duct 11. Through the arrangement of the induced draft fan 60, sufficient air pressure and air volume can be provided for the air circulation inside the air duct 11. At the same time, the induced draft fan 60 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.

[0169] Moreover, due to the arrangement of the induced draft fan 60, 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 113, so that the third air outlet 113 can also assist in air outlet.

[0170] Continue to refer to Figure 4 、 Figure 6 、 Figure 7 In the embodiment of the present invention, the heat exchanger 80 includes a first heat exchange part and a second heat exchange part which are connected to each other. A connection angle is formed between the first heat exchange part and the second heat exchange part, and the connection angle is an acute angle.

[0171] With such an arrangement, when the induced draft fan 60 is drawing in air, the contact area between the heat exchanger 80 and the incoming air can be increased, thereby improving the heat exchange effect. When the present invention can achieve 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, thereby ensuring the cooling air outlet or heating air outlet effect of the air conditioner cabinet 100.

[0172] In the above embodiment, 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. The water receiving tray is arranged between the heat exchanger 80 and the induced draft fan 60, and the connection part between the first heat exchange part and the second heat exchange part is arranged in the water receiving tray.

[0173] With such a setting, the condensed water generated by the heat exchanger 80 during heat exchange can flow along the heat exchanger 80 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.

[0174] Refer to Figure 16 、 Figure 17 As shown, in the embodiment of the present utility model, 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

[0175] 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.

[0176] Among them, the first cooling mode is a conventional cooling mode. During operation, the induced draft fan 60 operates, guides air to the first air outlet 111 through the air duct volute assembly 40, and guides air to the third air outlet 113 through the air outlet duct. The air guiding member 70 at the third air outlet 113 can be opened obliquely upward, enabling long-distance air supply obliquely upward to avoid directly blowing on the human body; the second cooling mode is a full-speed cooling mode. During operation, both the impeller assembly 50 and the induced draft fan 60 operate. The first air outlet 111, the second air outlet 112, and the third air outlet 113 are all opened. Air is guided to the first air outlet 111 through the air duct volute assembly 40, air is guided to the second air outlet 112 through the impeller assembly 50, and air is guided to the third air outlet 113 through the air outlet duct. The air guiding member 70 located at the third air outlet 113 is opened flatly, and the air conditioner cabinet 100 operates in the full-speed cooling mode to achieve large-volume air supply.

[0177] When the air conditioner cabinet 100 is in the heating mode, the impeller assembly 50 and the induced draft fan 60 operate. The second air outlet 112 and the third air outlet 113 are opened. Air is guided to the second air outlet 112 through the impeller assembly 50, and air is guided to the third air outlet 113 through the air outlet duct. And the air guiding member 70 located in the air duct 11 is opened obliquely downward to achieve long-distance air supply obliquely downward. Since the density of hot air is smaller than that of cold air, the blown hot air can cover the entire indoor space from bottom to top.

[0178] 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 113 are all opened, and both the impeller assembly 50 and the induced draft fan 60 operate, so that the hot air in the air duct 11 can be quickly discharged into the room.

[0179] The present utility model further provides an air conditioner, which includes an outdoor unit of the air conditioner and an air conditioner cabinet 100. The specific structure of the air conditioner cabinet 100 refers to the above embodiments. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one. Among them, the outdoor unit of the air conditioner is connected to the air conditioner cabinet 100 through a refrigerant pipe.

[0180] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the technical concept of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
