[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 6 An air conditioner according to an embodiment of the present utility model is described.

[0030] Reference Figure 1-Figure 3 According to an embodiment of the present invention, the air conditioner comprises a housing 1, an air duct assembly 2 and a heat exchanger component 3. The housing 1 has an air inlet 17 and an air outlet 18, and the heat exchanger component 3 is arranged between the air duct assembly 2 and the air inlet 17. The air duct volute 21 has an air duct 24, and the air outlet frame 22 has an air outlet channel 25, and the air outlet channel 25 connects the air duct 24 and the air outlet 18.

[0031] When the air conditioner is working, the wind wheel 23 drives the air flow to enter through the air inlet 17, and the wind wheel 23 drives the air flow to flow into the heat exchanger component 3 for heat exchange. The air flow after heat exchange flows into the air duct 24, and through the cooperation of the first docking structure 21a and the second docking structure 22a, the air flow is transferred from the air duct 24 to the air outlet channel 25. The air flow in the air outlet channel 25 flows to the air outlet, and the wind wheel 23 drives the air flow to be blown out into the room through the air outlet 18 to heat up or cool down the room.

[0032] The air duct assembly 2 is arranged in the housing 1 and includes an air duct volute 21, an air outlet frame 22 and a wind wheel 23, and the wind wheel 23 is arranged in the air duct volute 21. The air outlet frame 22 is connected to the air outlet end of the air duct volute 21, and the air outlet end of the air duct volute 21 includes a first docking structure 21a, and the air inlet end of the air outlet frame 22 has a second docking structure 22a docked with the first docking structure 21a. The docking cooperation between the first docking structure 21a and the second docking structure 22a can guide the airflow at the air outlet end of the air duct volute 21 to transition to the air inlet end of the air outlet frame 22, thereby reducing the air volume loss between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22.

[0033] The first docking structure 21a includes a first side wall 211, and the second docking structure 22a includes a second side wall 221 and a third side wall 222. The first side wall 211 extends in a direction close to the air outlet frame 22, and the second side wall 221 extends in a direction close to the air duct volute 21. The third side wall 222 is connected to an end of the second side wall 221 close to the air duct volute 21 and extends in a direction away from the central axis of the air outlet channel 25. There is an angle between the third side wall 222 and the second side wall 221, and the free end of the first side wall 211 faces the third side wall 222 and the first side wall 211 and the third side wall 222 are docked with each other.

[0034] The first side wall 211 constitutes a partial side wall of the air duct 24 , and the second side wall 221 and the third side wall 222 constitute a partial side wall of the air outlet channel 25 . The first side wall 211 extends in the direction close to the air outlet frame 22, and can guide the airflow in the air duct 24 toward the air inlet end of the air outlet frame 22; the second side wall 221 extends in the direction close to the air duct volute 21, and can guide the airflow at the air outlet end of the air duct volute 21, and can guide the airflow into the air outlet channel 25, and then the wind wheel 23 drives the airflow to accelerate and blow out through the air outlet 18; the free end of the first side wall 211 faces the third side wall 222 and the first side wall 211 is docked with the third side wall 222 to achieve the docking between the first docking structure 21a and the second docking structure 22a, which can guide the airflow to transition softly through the air duct 24 to the air outlet channel 25, reduce the air volume loss at the docking point between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22, and effectively avoid air flow backflow; and can reduce the noise generated by the airflow at the docking point between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22.

[0035] According to the air conditioner of the embodiment of the utility model, by arranging a first docking structure 21a at the air outlet end of the air duct volute 21 and arranging a second docking structure 22a docking with the first docking structure 21a at the air inlet end of the air outlet frame 22, and making an angle between the third side wall 222 of the second docking structure 22a and the second side wall 221 of the second docking structure 22a, and making the free end of the first side wall 211 of the first docking structure 21a face the third side wall 222 of the second docking structure 22a and dock with the first side wall 211, the air volume loss at the docking point between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22 can be reduced, and the noise generated by the air flow at the docking point between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22 can be reduced.

[0036] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the wall surface of the second side wall 221 facing the air outlet channel 25 is the first wall surface 223, the wall surface of the third side wall 222 facing the air duct volute 21 is the second wall surface 224, and the angle α between the second wall surface 224 and the first wall surface 223 ranges from 88° to 128°. For example, the angle α between the second wall 224 and the first wall 223 can be 88°, 95°, 110°, 120°, 129°, etc., and the angle α between the second wall 224 and the first wall 223 is not less than 88°, which can facilitate the docking and cooperation between the third side wall 222 of the air outlet frame 22 and the free end of the first side wall 211 of the air duct volute 21; because the third side wall 222 extends in a direction away from the central axis of the air outlet channel 25, and the angle α between the second wall 224 and the first wall 223 is not greater than 128°, the sealing effect of the docking point between the third side wall 222 of the air outlet frame 22 and the free end of the first side wall 211 of the air duct volute 21 can be improved, thereby reducing the possibility of air flow backflow.

[0037] For example, the angle between the second wall 224 and the first wall 223 is greater than 128°, and the third side wall 222 may extend in the direction close to the air duct volute 21. The third side wall 222 will have the effect of guiding the return air of the airflow, and may guide the return air of the airflow flowing to the joint between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22, or guide the airflow to the side of the air outlet frame 22 that is away from the air outlet channel 25.

[0038] By setting the angle α between the second wall 224 and the first wall 223 in the range of 88° to 128°, the docking cooperation between the third side wall 222 of the air outlet frame 22 and the free end of the first side wall 211 of the air duct volute 21 can be facilitated; and the sealing effect of the docking point between the third side wall 222 of the air outlet frame 22 and the free end of the first side wall 211 of the air duct volute 21 can be improved, thereby reducing the possibility of air flow backflow.

[0039] Reference Figure 2 and Figure 3 According to some embodiments of the utility model, the wall surface of the first side wall 211 facing the air duct 24 is the third wall surface 212, the wall surface of the first side wall 211 away from the air duct 24 is the fourth wall surface 213, the wall surface of the first side wall 211 facing the third side wall 222 is the fifth wall surface 214, the fifth wall surface 214 includes a first wall surface 215 and a second wall surface 216, the first wall surface 215 is connected to the third wall surface 212, the second wall surface 216 is connected between the first wall surface 215 and the fourth wall surface 213, the first wall surface 215 is a plane, and the second wall surface 216 is an arcuate surface.

[0040] The first wall surface 215 is a plane, which can facilitate the docking and cooperation between the fifth wall surface 214 of the first side wall 211 and the second wall surface 224 of the third side wall 222, thereby improving the sealing effect of the airflow between the free end of the first side wall 211 and the third side wall 222; the first wall surface 215 is a plane, and the second wall surface 216 is an arcuate surface, which can make the fifth wall surface 214 of the first side wall 211 and the fourth wall surface 213 have a smooth transition, which is convenient for the side of the first side wall 211 facing away from the air duct 24 to dock with the third side wall 222, and facilitate the assembly between the air outlet frame 22 and the air duct volute 21.

[0041] Reference Figure 3 According to some embodiments of the present invention, the angle β between the first wall surface 215 and the third wall surface 212 ranges from 54° to 94°. For example, the angle β between the first wall surface 215 and the third wall surface 212 can be 54°, 50°, 70°, 85°, 94°, etc. By making the angle β between the first wall surface 215 and the third wall surface 212 not less than 54°, it can be avoided that the angle between the fifth wall surface 214 and the third wall surface 212 is too small, which makes the top angle of the first side wall 211 facing the air duct 24 too sharp, and makes the air flow through the air duct 24 and the air outlet channel 25 The noise is too loud at the junction; by making the angle between the first wall surface 215 and the third wall surface 212 not greater than 94°, it can be avoided that the top angle of the first side wall 211 facing the air duct 24 is too large due to the angle between the fifth wall surface 214 and the third wall surface 212 is too large, making the docking between the free end of the first side wall 211 and the third side wall 222 more difficult, thereby weakening the sealing effect when the free end of the first side wall 211 and the third side wall 222 are docked.

[0042] By setting the angle β between the first wall surface 215 and the third wall surface 212 in the range of 54° to 94°, it is possible to avoid the angle between the fifth wall surface 214 and the third wall surface 212 being too small, which would make the top angle of the first side wall 211 facing the air duct 24 too sharp, and cause the airflow to make too much noise at the junction of the air duct 24 and the air outlet channel 25; and it is possible to avoid the angle between the fifth wall surface 214 and the third wall surface 212 being too large, which would make the top angle of the first side wall 211 facing the air duct 24 too large, making the docking between the free end of the first side wall 211 and the third side wall 222 more difficult, thereby weakening the sealing effect when the free end of the first side wall 211 and the third side wall 222 are docked.

[0043] Reference Figure 3 According to some embodiments of the present invention, the angle γ between the first wall surface 215 and the fourth wall surface 213 ranges from 86° to 126°. For example, the angle γ between the first wall surface 215 and the fourth wall surface 213 can be 86°, 90°, 105°, 115°, 126°, etc. By making the angle γ between the first wall surface 215 and the fourth wall surface 213 not less than 86°, it is possible to avoid the angle between the fourth wall surface 213 and the first wall surface 215 being too sharp to weaken the sealing effect of the docking fit between the first side wall 211 and the third side wall 222, and it is possible to avoid the free end of the first side wall 211 being too sharp to increase the noise of the airflow at the docking point between the air duct volute 21 and the air outlet frame 22; by making the angle between the first wall surface 215 and the fourth wall surface 213 not greater than 126°, it is possible to avoid the angle between the first wall surface 215 and the fourth wall surface 213 being too large to make the docking fit between the first side wall 211 and the third side wall 222 more difficult, thereby affecting the sealing effect of the docking fit between the first side wall 211 and the third side wall 222.

[0044] By setting the angle γ between the first wall surface 215 and the fourth wall surface 213 in the range of 86° to 126°, it is possible to avoid the angle between the fourth wall surface 213 and the first wall surface 215 being too sharp to weaken the sealing effect of the docking fit between the first side wall 211 and the third side wall 222, and it is possible to avoid the free end of the first side wall 211 being too sharp to increase the noise of the airflow at the docking point between the air duct volute 21 and the air outlet frame 22; and it is possible to avoid the angle between the first wall surface 215 and the fourth wall surface 213 being too large to make the docking fit between the first side wall 211 and the third side wall 222 more difficult, thereby affecting the sealing effect of the docking fit between the first side wall 211 and the third side wall 222.

[0045] Optionally, the third wall surface 212 and the fourth wall surface 213 of the first side wall 211 may be parallel to each other, and the angle β between the first wall portion 215 and the third wall surface 212 and the angle γ between the first wall portion 215 and the fourth wall surface 213 are complementary.

[0046] Reference Figure 3 According to some embodiments of the present invention, the spacing w1 between the first wall surface 215 and the second wall surface 224 ranges from 0 to 5 mm. For example, the spacing w1 between the first wall surface 215 and the second wall surface 224 can be 1 mm, 2 mm, 3 mm, 3.5 mm, 4 mm, etc. By making the spacing w1 between the first wall surface 215 and the second wall surface 224 greater than 0 mm, a certain assembly error is left between the first wall surface 215 and the second wall surface 224, which can facilitate the disassembly and assembly between the air outlet frame 22 and the air duct volute 21; by making the spacing between the fourth wall surface 213 and the second rib 229 less than 5 mm, the possibility of airflow flowing out between the first wall surface 215 and the second wall surface 224 due to the excessive spacing w1 between the first wall surface 215 and the second wall surface 224 can be reduced.

[0047] By making the distance w1 between the first wall surface 215 and the second wall surface 224 range from 0 to 5 mm, a certain assembly error is left between the first wall surface 215 and the second wall surface 224, which can facilitate the disassembly and assembly between the air outlet frame 22 and the air duct volute 21; and can reduce the possibility of airflow flowing out between the first wall surface 215 and the second wall surface 224 due to the excessive distance w1 between the first wall surface 215 and the second wall surface 224.

[0048] Reference Figure 3 According to some embodiments of the present invention, the wall surface of the second side wall 221 facing the air outlet channel 25 is the first wall surface 223, the wall surface of the first side wall 211 facing the air duct 24 is the third wall surface 212, and the distance between the plane where the first wall surface 223 is located and the plane where the third wall surface 212 is located is in the range of 0.5 to 2 mm. For example, the distance between the plane where the first wall surface 223 is located and the plane where the third wall surface 212 is located can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, etc. By ensuring that the distance between the plane where the first wall 223 is located and the plane where the third wall 212 is located is not less than 0.5 mm, a certain assembly error is allowed for the assembly between the duct volute 21 and the air outlet frame 22, and it can also ensure that the flow cross-section of the airflow in the air outlet frame 22 is not less than the flow cross-section of the airflow in the air outlet frame 22, thereby reducing the flow velocity of the airflow in the air outlet frame 22, thereby reducing the noise of the airflow passing through the joint between the air outlet frame 22 and the duct volute 21; by ensuring that the distance between the plane where the first wall 223 is located and the plane where the third wall 212 is located is not more than 2 mm, it can facilitate the assembly of the duct volute 21 and the air outlet frame 22, thereby facilitating the joint cooperation between the air outlet end of the duct volute 21 and the air inlet end of the air outlet frame 22, reducing the airflow flowing to the gap between the first side wall 211 and the second side wall 221, and the possibility of air leakage from the joint between the air outlet end of the duct volute 21 and the air inlet end of the air outlet frame 22.

[0049] By making the spacing between the plane where the first wall 223 is located and the plane where the third wall 212 is located in the range of 0.5 to 2 mm, a certain assembly error is allowed for the assembly between the air duct volute 21 and the air outlet frame 22, and it can also ensure that the flow cross-section of the airflow in the air outlet frame 22 is not less than the flow cross-section of the airflow in the air duct volute 21, thereby reducing the flow velocity of the airflow in the air outlet frame 22, thereby reducing the noise of the airflow when flowing through the joint between the air outlet frame 22 and the air duct volute 21, and a certain assembly error can be left for the assembly between the air duct volute 21 and the air outlet frame 22; and, it can facilitate the assembly of the air duct volute 21 and the air outlet frame 22, thereby facilitating the joint cooperation between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22, reducing the airflow flowing to the gap between the first side wall 211 and the second side wall 221, and the possibility of air leakage from the joint between the air outlet end of the air duct volute 21 and the air inlet end of the air outlet frame 22.

The first rib plate 217 can strengthen the structural strength of the first side wall 211, thereby enhancing the overall structural strength of the air duct volute 21; and when the air duct volute 21 is assembled with other components, the first rib plate 217 can play a positioning role, so that the assembly position between the air duct volute 21 and other components is accurate.

[0051] For example, when the air duct volute 21 and the air outlet frame 22 are assembled, the first rib plate 217 can play a role in positioning the air outlet frame 22 to ensure that the assembly position between the air duct volute 21 and the air outlet frame 22 is accurate.

[0053] The fourth side wall 225 is connected between the fifth side wall 226 and the third side wall 222, the fourth side wall 225 extends in a direction close to the first rib plate 217 and an angle is formed between the fourth side wall 225 and the third side wall 222, the fifth side wall 226 extends in a direction away from the central axis of the air outlet channel 25 and an angle is formed between the fifth side wall 226 and the fourth side wall 225, the fourth side wall 225 is opposite to the first side wall 211, and the fifth side wall 226 is opposite to the first rib plate 217. The fourth side wall 225 is connected between the fifth side wall 226 and the third side wall 222. The fourth side wall 225 extends in the direction close to the first rib plate 217 and there is an angle between the fourth side wall 225 and the third side wall 222. The fourth side wall 225 is opposite to the first side wall 211. For example, the airflow flows into the side of the air outlet frame 22 away from the air outlet channel 25 through the joint between the first side wall 211 and the third side wall 222. The fourth side wall 225 is connected between the fifth side wall 226 and the third side wall 222. A labyrinth structure can be formed on the side of the air outlet frame 22 away from the air outlet channel 25 to enhance the sealing effect of the side of the air outlet frame 22 away from the air outlet channel 25.

[0054] The fifth side wall 226 extends in a direction away from the central axis of the air outlet channel 25 and has an included angle with the fourth side wall 225. The fifth side wall 226 is opposite to the first rib plate 217, which can enhance the overall stability of the docking between the first docking structure 21a and the second docking structure 22a. Moreover, since there is an included angle between the fifth side wall 226 and the fourth side wall 225, the flow angle of the airflow in the space on the side of the air outlet frame 22 away from the air outlet channel 25 can be changed, thereby weakening the flow effect of the airflow in the space on the side of the air outlet frame 22 away from the air outlet channel 25.

[0055] For example, the airflow flows into the side of the air outlet frame 22 away from the air outlet channel 25 through the joint between the first side wall 211 and the third side wall 222, and there is an angle between the fourth side wall 225 and the third side wall 222, and there is an angle between the fifth side wall 226 and the fourth side wall 225. The flow angle of the airflow can be continuously changed to weaken the circulation effect of the airflow in the space on the side of the air outlet frame 22 away from the air outlet channel 25.

[0056] By providing a fourth side wall 225 and a fifth side wall 226 on the third side wall 222, the overall structural strength of the second docking structure 22a can be enhanced, and a maze-like structure can be formed on the side of the air outlet frame 22 facing away from the air outlet channel 25, thereby enhancing the sealing effect of the side of the air outlet frame 22 facing away from the air outlet channel 25 and effectively reducing the possibility of airflow flowing out through the side of the air outlet frame 22 facing away from the air outlet channel 25.

[0057] Reference Figure 3According to some embodiments of the utility model, a first convex rib 227 is formed on one side of the fifth side wall 226 facing the first rib plate 217. The first convex rib 227 can enhance the structural strength of the fifth side wall 226, thereby enhancing the overall structural strength of the air outlet frame 22; and, since the fifth side wall 226 is opposite to the first rib plate 217, the first convex rib 227 can play a positioning role in the cooperation between the fifth side wall 226 and the first rib plate 217, thereby making the assembly position of the air duct volute 21 and the air outlet frame 22 accurate; the first convex rib 227 can also increase the windproof area between the fifth side wall 226 and the first rib plate 217, thereby enhancing the sealing effect between the fifth side wall 226 and the first rib plate 217, and reducing the possibility of airflow leakage through the gap between the fifth side wall 226 and the first rib plate 217.

[0058] Reference Figure 3 According to some embodiments of the utility model, a second rib plate 228 is connected to the side of the third side wall 222 facing the air duct volute 21, and the second rib plate 228 is located between the first side wall 211 and the fourth side wall 225. The second rib plate 228 can enhance the structural strength of the third side wall 222, thereby enhancing the overall structural strength of the air outlet frame 22; and, since the second rib plate 228 is located between the first side wall 211 and the fourth side wall 225, the sealing effect between the first side wall 211 and the fourth side wall 225 can be enhanced, and the possibility of airflow flowing out between the first side wall 211 and the fourth side wall 225 can be reduced; the second rib plate 228 can also play a positioning role in the cooperation between the first side wall 211 and the fourth side wall 225, so that the assembly position of the air duct volute 21 and the air outlet frame 22 is accurate.

[0059] Among them, a second rib 229 is formed on the side of the second rib 228 facing the first side wall 211, and the second rib 229 can enhance the structural strength of the second rib 228; and the second rib 229 can limit the first side wall 211, and when the air duct volute 21 and the air outlet frame 22 are assembled, the accurate assembly position of the air duct volute 21 and the air outlet frame 22 can be ensured.

[0060] Optionally, there may be a plurality of second convex ribs 229 , and the plurality of second convex ribs 229 are formed on the second rib plate 228 and are spaced apart along the up-and-down direction of the second rib plate 228 .

[0061] Optionally, according to an embodiment of the utility model, the wall surface of the first side wall 211 facing away from the air duct 24 is the fourth wall surface 213, and the spacing w2 between the fourth wall surface 213 and the second convex rib 229 ranges from 0 to 5 mm. For example, the spacing w2 between the fourth wall surface 213 and the second convex rib 229 can be 1 mm, 2 mm, 3 mm, 3.5 mm, 4 mm, etc. By making the spacing w2 between the fourth wall surface 213 and the second convex rib 229 greater than 0 mm, a certain assembly error is allowed between the fourth wall surface 213 and the second convex rib 229, which is convenient for production. The disassembly and assembly between the wind frame 22 and the air duct volute 21 can be performed by stuffing a filler into the gap w2 between the fourth wall 213 and the second convex rib 229. The filler is preferably flannel or sponge to enhance the sealing effect between the first side wall 211 and the second convex rib 229. By reducing the distance between the fourth wall 213 and the second convex rib 229 to less than 5 mm, the possibility of airflow flowing out through the gap between the first side wall 211 facing away from the air duct 24 and the second convex rib 229 due to excessive distance w2 between the fourth wall 213 and the second convex rib 229 can be reduced.

[0062] By setting the spacing w2 between the fourth wall 213 and the second convex rib 229 to be in the range of 0 to 5 mm, a certain assembly error is allowed between the fourth wall 213 and the second convex rib 229, so as to facilitate the disassembly and assembly between the air outlet frame 22 and the air duct volute 21. Filler can be stuffed into the spacing w2 between the fourth wall 213 and the second convex rib 229. The filler is preferably flannel or sponge to enhance the sealing effect between the first side wall 211 and the second convex rib 229; and the possibility of airflow flowing out through the gap between the first side wall 211 facing away from the air duct 24 and the second convex rib 229 due to the excessive spacing w2 between the first side wall 211 and the second convex rib 229 can be reduced.
