Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] In related technologies, the air outlet temperature of air conditioners can only be controlled by adjusting the temperature of the heat exchanger. This results in poor comfort when directly blowing cool or hot air, which is quite different from natural wind. Furthermore, the indoor airflow becomes relatively dry after passing through the heat exchanger for cooling. Prolonged cooling leads to low indoor humidity and poor comfort. Utility Model Content

[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] The following is for reference. Figures 1-11 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0047] like Figures 1-6 As shown, the air conditioner 100 according to an embodiment of the present invention includes a housing 10 and a fan 60. The housing 10 includes a front housing 1001 and a rear housing 1004, and the rear housing 1004 can be connected to the rear side of the front housing 1001. The front housing 1001 is provided with a first air outlet 1021 and a second air outlet 1022. The fan 60 is disposed inside the rear housing 1004, that is, the first air outlet 1021 and the second air outlet 1022 are located in front of the fan 60.

[0048] There is an air duct 101 between the impeller 60 and the front shell 1001. The air duct 101 includes a main channel 1011, a first branch channel 1012 and a second branch channel 1013. The first branch channel 1012 connects the main channel 1011 and the first air outlet 1021, and the second branch channel 1013 connects the main channel 1011 and the second air outlet 1022.

[0049] The front shell 1001 has a ventilation cavity 1220, which is connected to the external space of the front shell 1001. The ventilation cavity 1220 is located between the first branch channel 1012 and the second branch channel 1013. The first branch channel 1012 is connected to the ventilation cavity 1220 through the first vent 1061, and the second branch channel 1013 is connected to the ventilation cavity 1220 through the second vent 1062.

[0050] Specifically, such as Figures 1-4 As shown, when the first air outlet 1021 and the second air outlet 1022 are open and the air conditioner 100 is in cooling mode, high-speed air flows out from the first air outlet 1021 and the second air outlet 1022, which can form negative pressure zones in the first branch channel 1012 and the second branch channel 1013 respectively. At this time, the ventilation cavity 1220 can be used as an air intake cavity. The air with a higher temperature outside the outer casing 10 can be introduced into the first branch channel 1012 and the second branch channel 1013 through the ventilation cavity 1220 and mixed with the air with a lower temperature in the first branch channel 1012 and the second branch channel 1013. Finally, it is sent out from the first air outlet 1021 and the second air outlet 1022, and so on.

[0051] Therefore, by introducing external air, on the one hand, the air temperature of the first air outlet 1021 and the second air outlet 1022 can be gradually reduced to avoid discomfort caused by sudden changes in air temperature; on the other hand, the hot air blown out by the first air outlet 1021 and the second air outlet 1022 will not be too dry, but will have higher humidity, making the airflow softer and more comfortable.

[0052] like Figures 1-4 As shown, when the first air outlet 1021 and the second air outlet 1022 are open and the air conditioner 100 is in heating mode, high-speed air flows out from the first air outlet 1021 and the second air outlet 1022, which can form negative pressure zones in the first branch channel 1012 and the second branch channel 1013 respectively. At this time, the ventilation cavity 1220 can be used as an air intake cavity. The air with a lower temperature outside the outer casing 10 can be introduced into the first branch channel 1012 and the second branch channel 1013 through the ventilation cavity 1220 and mixed with the air with a higher temperature in the first branch channel 1012 and the second branch channel 1013. Finally, it is sent out from the first air outlet 1021 and the second air outlet 1022, and so on.

[0053] Therefore, by introducing external air, on the one hand, the outlet air temperature of the first air outlet 1021 and the second air outlet 1022 can be gradually increased to avoid discomfort caused by sudden changes in outlet air temperature, and on the other hand, the humidity of the cool air blown out by the first air outlet 1021 and the second air outlet 1022 is moderate.

[0054] like Figure 5 and Figure 6 As shown, when the first air outlet 1021 and the second air outlet 1022 are covered, high-pressure zones can be formed at the first branch channel 1012 and the second branch channel 1013, respectively. At this time, the ventilation cavity 1220 can be used as an exhaust cavity, allowing at least a portion of the airflow in the first branch channel 1012 to enter the ventilation cavity 1220 through the first ventilation port 1061, and allowing at least a portion of the airflow in the second branch channel 1013 to enter the ventilation cavity 1220 through the second ventilation port 1062, and finally being discharged to the outside of the outer casing 10 through the ventilation cavity 1220.

[0055] According to the embodiment of the present invention, the air conditioner 100, by providing a ventilation cavity 1220 between the first branch channel 1012 and the second branch channel 1013, when high-speed flowing gas flows out from the first air outlet 1021 and the second air outlet 1022, negative pressure zones can be formed at the first branch channel 1012 and the second branch channel 1013 respectively. This allows air from outside the outer casing 10 to be introduced into the first branch channel 1012 and the second branch channel 1013 through the ventilation cavity 1220 for mixing, and finally delivered out from the first air outlet 1021 and the second air outlet 1022. This improves the mixing effect of the airflow to a certain extent, effectively fine-tunes the airflow temperature and humidity at the first air outlet 1021 and the second air outlet 1022, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0056] like Figure 4 and Figure 6 As shown, according to some embodiments of the present invention, the outer shell 10 is provided with a wind turbine housing 13 and an air outlet frame. The wind turbine 60 is disposed inside the wind turbine housing 13. The air outlet frame is connected between the wind turbine housing 13 and the front shell 1001. Specifically, the rear side of the air outlet frame is connected to the wind turbine housing 13, and the front side of the air outlet frame is connected to the front shell 1001. The wind turbine housing 13 defines a part of the air outlet duct 101, and the air outlet frame defines another part of the air outlet duct 101. The air outlet frame defines the main channel 1011, the first branch channel 1012, and the second branch channel 1013. The air outlet frame itself or the air outlet frame and the front shell 1001 define a ventilation cavity 1220.

[0057] In the above technical solution, by separating the air outlet frame from the impeller housing 13 and using multiple structural components to define the air outlet 101, the structure of the impeller housing 13 and the air outlet frame can be simplified, the molding difficulty of the impeller housing 13 and the air outlet frame can be reduced, which is conducive to reducing costs and improving production efficiency.

[0058] like Figure 4 and Figure 6As shown, in some embodiments, the air conditioner 100 further includes a diverter 124, which is at least partially disposed in the main channel 1011 and is used to guide the airflow in the main channel 1011 to flow into the first branch channel 1012 and the second branch channel 1013 respectively. The diverter 124 protrudes from the plane where the first vent 1061 and / or the second vent 1062 are located.

[0059] In other words, in the airflow direction, the diverter 124 is located upstream of the first vent 1061 and the second vent 1062, and protrudes from the plane where the first vent 1061 and / or the plane where the second vent 1062 are located, so that the diverter 124 can block the airflow, thereby creating a large pressure difference in the area where the first vent 1061 and the second vent 1062 are located, which is conducive to airflow. In this cycle, the airflow mixing effect can be improved, and the temperature and humidity of the airflow from the first air outlet 1021 and the second air outlet 1022 can be effectively fine-tuned to a certain extent, making the temperature and humidity of the airflow more comfortable.

[0060] In some specific embodiments, the distance between the wall and the diverter 124 that is disposed opposite to the diverter 124 in at least one of the first branch channel 1012 and the second branch channel 1013 is S1, and the width of the first branch channel 1012 or the second branch channel 1013 at the position of the corresponding vent away from the diverter 124 is S2, where S1 is less than S2.

[0061] Specifically, such as Figure 4 and Figure 6 As shown, in the cross-section of the air conditioner 100, the distance between the wall and the diverter 124 opposite to the first branch channel 1012 and the diverter 124 is S1, and the width of the first branch channel 1012 at the position of the first vent 1061 away from the diverter 124 is S2, where S1 is less than S2; the distance between the wall and the diverter 124 opposite to the second branch channel 1013 and the diverter 124 is S1, and the width of the second branch channel 1013 at the position of the second vent 1062 away from the diverter 124 is S2, where S1 is less than S2.

[0062] Therefore, by providing a diverter 124 in the first branch channel 1012 and / or the second branch channel 1013, the flow area of ​​at least a portion of the first branch channel 1012 and the second branch channel 1013 gradually expands along the airflow direction. This results in a negative pressure zone being formed at the position of the first branch channel 1012 near the first vent 1061 and the position of the second branch channel 1013 near the second vent 1062 when the first air outlet 1021 and the second air outlet 1022 are in the open state. This allows for better airflow through the ventilation cavity 1220, further enhancing the airflow mixing effect.

[0063] In some specific embodiments, the diverter 124 has a first diverting surface 1241 and a second diverting surface 1242 arranged at an angle. One end of the first diverting surface 1241 and one end of the second diverting surface 1242 are connected. The other end of the first diverting surface 1241 and the other end of the second diverting surface 1242 extend into the first branch channel 1012 and the second branch channel 1013 respectively along the air outlet direction in a direction away from each other.

[0064] In the above technical solution, by setting a first diversion surface 1241 and a second diversion surface 1242 in the diversion component 124, the diversion effect can be corrected by the diversion component 124, so that the airflow in the main channel 1011 can be better diverted. The airflow in the main channel 1011 can be introduced into the first branch channel 1012 under the guidance of the first diversion surface 1241 and into the second branch channel 1013 under the guidance of the second diversion surface 1242, so as to ensure that the air volume of the first air outlet 1021 and the second air outlet 1022 can meet the requirements.

[0065] In addition, the diverter 124 can block the airflow, so that when the first air outlet 1021 and the second air outlet 1022 are in the open state, the ventilation cavity 1220 can better draw air, thereby effectively fine-tuning the airflow temperature and humidity at the first air outlet 1021 and the second air outlet 1022.

[0066] like Figure 4 As shown, in order to ensure the diversion effect of the diversion component 124 and reduce air volume loss, the included angle of the cross-section S3 at the connection of the first diversion surface 1241 and the second diversion surface 1242 is an acute angle. For example, the included angle γ of the cross-section S3 at the connection of the first diversion surface 1241 and the second diversion surface 1242 can be less than or equal to 30°.

[0067] like Figure 4 and Figure 6 As shown, in some examples, the projection of at least one of the first diversion surface 1241 and the second diversion surface 1242 onto the plane where the corresponding vent is located partially overlaps with the vent.

[0068] This configuration allows for several advantages. First, when the first air outlet 1021 and the second air outlet 1022 are open, the first diversion surface 1241 partially blocks the first ventilation opening 1061, or the second diversion surface 1242 partially blocks the second ventilation opening 1062. This allows for a better pressure differential to be formed in the area where the first ventilation opening 1061 or the second ventilation opening 1062 is located, significantly improving the airflow effect and further enhancing the airflow mixing effect. Second, when the first air outlet 1021 and the second air outlet 1022 are covered, the first diversion surface 1241 can guide part of the airflow in the first branch channel 1012 to the first ventilation opening 1061, and the second diversion surface 1242 can guide part of the airflow in the second branch channel 1013 to the second ventilation opening 1062, ultimately being discharged outside the outer casing 10 through the ventilation cavity 1220.

[0069] like Figure 4 and Figure 6 As shown, in some embodiments, the air outlet frame includes a first frame 11 and a second frame 12. Specifically, one side of the first frame 11 is connected to the impeller housing 13, and the other side of the first frame 11 is connected to one side of the second frame 12. The other side of the second frame 12 is connected to the front housing 1001. The first frame 11 defines a main channel 1011, and the second frame 12 defines a first branch channel 1012 and a second branch channel 1013.

[0070] In some specific embodiments, the impeller housing 13 includes a volute tongue 131 and a volute shell 132 disposed opposite to each other, and the first frame 11 includes a first side plate 111 and a second side plate 112 disposed opposite to each other in the left-right direction. The front side of the first side plate 111 is connected to the second frame 12 and the rear side of the first side plate 111 is connected to the volute tongue 131. The front side of the second side plate 112 is connected to the second frame 12 and the rear side of the second side plate 112 is connected to the volute shell 132. A main channel 1011 is defined between the first side plate 111 and the second side plate 112.

[0071] In some specific embodiments, the second frame 12 includes a frame body 121 and a partition 122. The partition 122 is disposed inside the frame body 121 to divide the inner cavity of the frame body 121 into a first branch channel 1012 and a second branch channel 1013. A first vent 1061 and a second vent 1062 are disposed in the partition 122.

[0072] The front shell 1001 includes a front panel 1002, which is located on the side of the partition 122 facing away from the main channel 1011. A ventilation cavity 1220 is defined between the front panel 1002 and the partition 122. The first air outlet 1021 and the second air outlet 1022 are located on both sides of the front panel 1002.

[0073] In the above technical solution, by setting the air outlet frame as a split first frame 11 and second frame 12, and using multiple structural components to define the main channel 1011, the first branch channel 1012, and the second branch channel 1013, the structure of the air outlet frame can be simplified, the molding difficulty of the air outlet frame can be reduced, and it is beneficial to reduce costs and improve production efficiency. Furthermore, the front panel 1002 can cover the middle partition 122, ensuring that the air conditioner 100 has a smoother and more aesthetically pleasing appearance, thus enhancing the visual experience.

[0074] Furthermore, a ventilation cavity 1220 is defined between the partition 122 and the front panel 1002. When the first air outlet 1021 and the second air outlet 1022 are open, the ventilation cavity 1220 can function as an air intake cavity, effectively increasing the number of channels for introducing external air. This increases the airflow volume, improves the airflow mixing effect, and effectively fine-tunes the airflow temperature and humidity at the first air outlet 1021 and the second air outlet 1022, making the temperature and humidity of the airflow more comfortable and enhancing the user experience. When the first air outlet 1021 and the second air outlet 1022 are covered, the ventilation cavity 1220 can function as an exhaust cavity, effectively increasing the number of channels for exhausting internal air. This increases the exhaust volume and meets the user's needs.

[0075] like Figure 4 and Figure 6 As shown, in some specific embodiments, the partition 122 includes a first guide plate 1221 and a second guide plate 1222. The first guide plate 1221 and the second guide plate 1222 are arranged at an angle, and the first guide plate 1221 and the second guide plate 1222 extend away from each other along the air outlet direction. The first guide plate 1221 forms part of the wall of the first branch channel 1012, and the second guide plate 1222 forms part of the wall of the second branch channel 1013.

[0076] The front panel 1002 is connected to the first guide plate 1221 and the second guide plate 1222 at both ends to define the ventilation cavity 1220. The first ventilation port 1061 is provided on the first guide plate 1221 and the second ventilation port 1062 is provided on the second guide plate 1222.

[0077] In the above technical solution, by setting the partition 122 as the first guide plate 1221 and the second guide plate 1222, the airflow in the main channel 1011 can be split, and the air in the main channel 1011 can be guided to the first branch channel 1012 and the second branch channel 1013 respectively, so as to ensure that the air volume of the first air outlet 1021 and the second air outlet 1022 can meet the needs.

[0078] Furthermore, the first guide plate 1221, the second guide plate 1222, and the front panel 1002 combine to form a triangular-like structure, which occupies little space. While ensuring the diversion effect, it can define the ventilation cavity 1220, so that when the first air outlet 1021 and the second air outlet 1022 are open, external air can enter the ventilation cavity 1220, and then enter the first branch channel 1012 through the first ventilation port 1061, and enter the second branch channel 1013 through the second ventilation port 1062, and finally be discharged through the first air outlet 1021 and the second air outlet 1022. Since the front panel 1002 is located between the first air outlet 1021 and the second air outlet 1022, it can form the effect of air outlets on both sides and air intake or exhaust in the middle. The introduced external air can effectively fine-tune the temperature and humidity of the airflow from the first air outlet 1021 and the second air outlet 1022 to a certain extent, making the temperature and humidity of the airflow more comfortable.

[0079] In an embodiment where the air conditioner 100 includes a diverter 124 and a partition 122 includes a first guide plate 1221 and a second guide plate 1222, the diverter 124 may be disposed on the side of the partition 122 facing away from the front panel 1002. The diverter 124 protrudes from the first guide plate 1221 and is located on the side of the first vent 1061 near the main channel 1011. The diverter 124 also protrudes from the second guide plate 1222 and is located on the side of the first vent 1061 near the main channel 1011. The first diverter surface 1241 is upstream of the first vent 1061 in the airflow direction, and the second diverter surface 1242 is upstream of the second vent 1062 in the airflow direction.

[0080] When the first air outlet 1021 and the second air outlet 1022 are open, a portion of the airflow in the main channel 1011 enters the first branch channel 1012 under the guidance of the first diversion surface 1241, and mixes with the airflow flowing into the first branch channel 1012 from the first vent 1061, and is finally discharged from the first air outlet 1021; a portion of the airflow in the main channel 1011 enters the second branch channel 1013 under the guidance of the second diversion surface 1242, and mixes with the airflow flowing into the second branch channel 1013 from the second vent 1062, and is finally discharged from the second air outlet 1022.

[0081] When the first air outlet 1021 and the second air outlet 1022 are covered, a portion of the airflow in the main channel 1011 enters the first branch channel 1012 under the guidance of the first diversion surface 1241. Then, a portion of the airflow flows into the ventilation cavity 1220 from the first vent 1061 and is finally discharged to the external space from the first diffuser hole 1003. A portion of the airflow in the main channel 1011 enters the second branch channel 1013 under the guidance of the second diversion surface 1242. Then, a portion of the airflow flows into the ventilation cavity 1220 from the second vent 1062 and is finally discharged to the external space from the first diffuser hole 1003.

[0082] like Figures 7-9 As shown, the second frame 12 or the front shell 1001 has a positioning post 1211 and a first connecting hole 1212. The first frame 11 has a positioning hole and a second connecting hole (not shown in the figure). The positioning post 1211 is inserted into the positioning hole. The second frame 12 or the front shell 1001 is connected to the first frame 11 by fasteners. The fasteners pass through the first connecting hole 1212 and the second connecting hole, thereby ensuring the reliability of the connection between the second frame 12 or the front shell 1001 and the first frame 11.

[0083] like Figure 10 and Figure 11 As shown, there are multiple first vents 1061 and multiple second vents 1062. The multiple first vents 1061 are arranged at intervals along the length of the first guide plate 1221, and the multiple second vents 1062 are arranged at intervals along the length of the second guide plate 1222. This arrangement can ensure the structural strength of the partition 122.

[0084] like Figure 4 and Figure 6 As shown, in some specific embodiments, the front panel 1002 is provided with a plurality of first ventilation holes 1003, which are connected to the ventilation cavity 1220 and the external space of the front shell 1001.

[0085] The multiple first ventilation holes 1003 can be arranged in an array. For example, the multiple first ventilation holes 1003 can be arranged in the length and width directions of the front panel 1002. Of course, the multiple first ventilation holes 1003 can also be arranged in other ways.

[0086] Therefore, by providing multiple first air diffusers 1003 on the front panel 1002, when the first air outlet 1021 and the second air outlet 1022 are covered, the air entering the ventilation cavity 1220 is dispersed during the process of being discharged from the multiple first air diffusers 1003, which can make the wind blow more gently towards the user and improve the user's windless experience.

[0087] like Figure 4 , Figure 6 as well as Figures 10-11 As shown, in some embodiments, a sway assembly 40 is provided in the first branch channel 1012. The sway assembly 40 includes a connecting rod 41 and a plurality of sway blades 42. The plurality of sway blades 42 are rotatably disposed on the first guide plate 1221. The connecting rod 41 is connected to the plurality of sway blades 42 so that the plurality of sway blades 42 are linked together. The sway assembly 40 can adjust the airflow direction in the first branch channel 1012 so that the airflow direction of the first air outlet 1021 meets the usage requirements.

[0088] In some embodiments, a sway assembly 40 is provided in the second branch channel 1013. The sway assembly 40 includes a connecting rod 41 and a plurality of sway blades 42. The plurality of sway blades 42 are rotatably disposed on the second guide plate 1222. The connecting rod 41 is connected to the plurality of sway blades 42 so that the plurality of sway blades 42 are linked together. The sway assembly 40 can adjust the airflow direction in the second branch channel 1013 so that the airflow direction of the second air outlet 1022 meets the usage requirements.

[0089] like Figures 1-6 As shown, according to some embodiments of the present invention, the air conditioner 100 further includes an air guide assembly 20, which includes a movable first air guide member 21 and a second air guide member 22. The first air guide member 21 and the second air guide member 22 are respectively used to cover or open the first air outlet 1021 and the second air outlet 1022. Specifically, the first air guide member 21 is used to cover or open the first air outlet 1021, and the second air guide member 22 is used to cover or open the second air outlet 1022. Both the first air guide member 21 and the second air guide member 22 are provided with a plurality of second air diffusers 201.

[0090] The air conditioner 100 has a first air supply state and a second air supply state.

[0091] In the first air supply state, each of the first air guide 21 and the second air guide 22 opens its corresponding air outlet so that the ventilation cavity 1220 forms an air intake cavity.

[0092] Specifically, in this state, the first air guide 21 opens the first air outlet 1021, and the second air guide 22 opens the second air outlet 1022. High-speed flowing gas flows out from the first air outlet 1021 and the second air outlet 1022, which can respectively form negative pressure zones at the first branch channel 1012 and the second branch channel 1013. Air outside the outer casing 10 can enter the ventilation cavity 1220 through multiple first air diffusers 1003 on the front panel 1002, and then enter the first branch channel 1012 through the first vent 1061 and mix with the air in the first branch channel 1012. It then enters the second branch channel 1013 through the second vent 1062 and mixes with the air in the second branch channel 1013. Finally, it is sent out from the first air outlet 1021 and the second air outlet 1022. By introducing external air, the air temperature of the first air outlet 1021 and the second air outlet 1022 gradually changes, avoiding discomfort caused by sudden changes in air temperature. On the other hand, the humidity of the air blown out by the first air outlet 1021 and the second air outlet 1022 is moderate.

[0093] In the second air supply state, each of the first air guide 21 and the second air guide 22 covers the corresponding air outlet so that the ventilation cavity 1220 forms an exhaust cavity.

[0094] Specifically, in this state, the first air guide 21 covers the first air outlet 1021, the second air guide 22 covers the second air outlet 1022, the first branch channel 1012 and the second branch channel 1013 form separate high-pressure zones. A portion of the airflow entering the first branch channel 1012 can enter the ventilation cavity 1220 through the first vent 1061 and then exit through the multiple first air diffusers 1003 on the front panel 1002. Another portion of the airflow can exit through the multiple second air diffusers 201 of the first air guide 21. A portion of the airflow entering the second branch channel 1013 can enter the ventilation cavity 1220 through the second vent 1062 and then exit through the multiple first air diffusers 1003 on the front panel 1002. Another portion of the airflow can exit through the multiple second air diffusers 201 of the second air guide 22. This allows airflow to be discharged from multiple first air vents 1003 on the front panel 1002 and multiple second air vents 201 on the first air guide 21 and the second air guide 22, effectively increasing the airflow and cooling capacity without a draft.

[0095] Of course, the air supply state of the air conditioner 100 is not limited to the two mentioned above. During operation, the air conditioner 100 can also control the first air guide 21 and the second air guide 22 to swing periodically. During the swing of the first air guide 21 and the second air guide 22, the positive and negative pressure in the first branch channel 1012 and the second branch channel 1013 switch, so that the ventilation cavity 1220 switches between the air intake function and the air exhaust function, thereby making the air conditioner 100 form an intake and exhaust effect similar to breathing.

[0096] In the above technical solution, by setting the air guide component 20, the switching between the first air supply state and the second air supply state can be realized, thereby meeting a variety of usage needs.

[0097] According to some embodiments of the present invention, in the cross-section of the air conditioner 100, the air conditioner 100 has a center line, and the first air outlet 1021 and the second air outlet 1022 are symmetrically arranged about the center line.

[0098] In some embodiments, the rotation center of the wind turbine 60 is located on one side of the centerline, and the first branch channel 1012 and the second branch channel 1013 are arranged asymmetrically about the centerline.

[0099] like Figure 4 As shown, in the cross-section of the air conditioner 100, the air conditioner 100 has a centerline P, and the first air outlet 1021 and the second air outlet 1022 are located on both sides of the centerline P (e.g., Figure 1 As shown on the left and right sides, the extension directions of the first branch channel 1012 and the second branch channel 1013 are not equal to the angles with the center line P.

[0100] Specifically, the angle between the extension direction of the first branch channel 1012 and the center line P is β1, and the angle between the extension direction of the second branch channel 1013 and the center line P is β2, where β1 is not equal to β2.

[0101] In this embodiment, the center of the impeller 60 is located on one side of the center line P, that is, the impeller 60 is offset relative to the center line P. Therefore, by limiting the above conditions, the air volume loss can be reduced and the temperature regulation efficiency of the air conditioner 100 can be improved.

[0102] Furthermore, the first air outlet 1021 and the second air outlet 1022 are arranged symmetrically about the center line P.

[0103] Since the first air outlet 1021 and the second air outlet 1022 are exposed on the outside of the outer casing 10, they serve as the appearance structure of the air conditioner 100. By defining the symmetrical arrangement of the first air outlet 1021 and the second air outlet 1022 about the center line P, the appearance of the air conditioner 100 is symmetrical, which is beneficial to improving the visual experience.

[0104] According to some embodiments of this utility model, the air conditioner 100 is a cabinet air conditioner 100. The air conditioner 100 can be the indoor unit of a split-type air conditioner or an integrated air conditioner 100.

[0105] The following describes a specific embodiment of the present invention, taking air conditioner 100 as an example of a cabinet air conditioner.

[0109] The outer casing 10 has an air duct 101 and an air duct 101 cavity. The air duct 101 includes a main channel 1011, a first branch channel 1012 and a second branch channel 1013. The first branch channel 1012 connects the first air outlet 1021 and the main channel 1011. The second branch channel 1013 connects the second air outlet 1022 and the main channel 1011. The ventilation cavity 1220 is connected to the first branch channel 1012 through the first ventilation port 1061 and to the second branch channel 1013 through the second ventilation port 1062. A plurality of first air diffusers 1003 connect the ventilation cavity 1220 and the external space of the front casing 1001. Among them, the main channel 1011 extends from back to front and gradually to the left, the first branch channel 1012 extends from back to front and gradually to the left, and the second branch channel 1013 extends from back to front and gradually to the right. The angle β1 between the first branch channel 1012 and the center line P is greater than the angle β2 between the second branch channel 1013 and the center line P.

[0110] The impeller housing 13 and the air outlet frame are located inside the outer shell 10. The impeller housing 13 is located inside the rear shell 1004 and includes a volute 132 and a volute tongue 131. The volute 132 and the volute tongue 131 define a portion of the air outlet duct 101. The air outlet frame includes a first frame 11 and a second frame 12. The rear side of the first frame 11 is connected to the impeller housing 13, the front side of the first frame 11 is connected to the rear side of the second frame 12, and the front side of the second frame 12 is connected to the front shell 1001.

[0111] The first frame 11 defines the main channel 1011 of the air duct 101 and includes a first side plate 111 and a second side plate 112, which are arranged opposite to each other in the left-right direction.

[0112] The second frame 12 includes a frame body 121 and a partition 122. The partition 122 is disposed inside the frame body 121. The partition 122 can define a first branch channel 1012 and a second branch channel 1013 with the frame body 121. The partition 122 includes a first guide plate 1221 and a second guide plate 1222. One end of the first guide plate 1221 and one end of the second guide plate 1222 are connected and extend from back to front in a direction away from each other. A first vent 1061 is disposed on the first guide plate 1221 and a second vent 1062 is disposed on the second guide plate 1222.

[0113] The front panel 1002 is located on the front side of the partition 122, and the left and right ends of the front panel 1002 are respectively connected to the other end of the first guide plate 1221 and the other end of the second guide plate 1222. The front panel 1002, the first guide plate 1221, and the second guide plate 1222 define a ventilation cavity 1220.

[0114] The diverter 124 is disposed on the side of the partition 122 facing the wind turbine housing 13. The diverter 124 has a first diverting surface 1241 and a second diverting surface 1242 arranged at an angle. The first diverting surface extends at least partially into the first branch channel 1012, and the second diverting surface 1242 extends at least partially into the second branch channel 1013.

[0115] The fan includes a fan wheel 60, which can be a cross-flow fan wheel 60. The fan wheel 60 is rotatably disposed inside the fan wheel housing 13. The rotation center of the fan wheel 60 is located to the right of the center line P of the air conditioner 100. The volute tongue 131 is located on the left wall of the fan wheel housing 13 and extends to the right.

[0116] A heat exchanger 50 is disposed between the air inlet 108 and the impeller 60 of the rear housing 1004. The heat exchanger 50 includes a first heat exchange section 51 and a second heat exchange section 52. The first heat exchange section 51 is disposed near the left side of the rear housing 1004, and the second heat exchange section 52 is disposed near the rear side of the rear housing 1004. The first heat exchange section 51 and the second heat exchange section 52 are connected by an arc transition. A heating element 70 is provided between the impeller 60 and the heat exchanger 50.

[0117] The air guide assembly 20 includes a first air guide 21, a second air guide 22, a first upper motor 23, and a second upper motor 24.

The second air guide 22 is rotatably disposed at the second air outlet 1022. The second upper motor 24 is disposed above the second air guide 22 and connected to the second air guide 22 to drive the second air guide 22 to rotate.

[0118] The oscillating blade assembly 40 includes a connecting rod 41 and multiple oscillating blades 42. The connecting rod 41 is connected to the multiple oscillating blades 42 to enable the multiple oscillating blades 42 to move in tandem. The oscillating blade assembly 40 is provided in both the first branch channel 1012 and the second branch channel 1013.

[0119] When the air conditioner 100 is working, the fan wheel 60 can drive the air in the external environment to flow through the air inlet 108 and through the heat exchanger 50. When the heat exchanger 50 is working, it can exchange heat with the passing air to form hot air or cold air. The airflow after heat exchange can pass through the air duct 101 to the outside.

[0120] The air conditioner 100 has at least a first air supply state and a second air supply state.

[0121] like Figures 1-4 As shown, in the first air supply state, the first air guide 21 opens the first air outlet 1021, and the second air guide 22 opens the second air outlet 1022. High-speed flowing gas flows out from the first air outlet 1021 and the second air outlet 1022, which can respectively form negative pressure zones at the first branch channel 1012 and the second branch channel 1013. Air outside the outer casing 10 can enter the ventilation cavity 1220 through multiple first air diffusers 1003 on the front panel 1002, and then be introduced into the first branch channel 1012 through the first vent 1061 and mixed with the air in the first branch channel 1012. It can also be introduced into the second branch channel 1013 through the second vent 1062 and mixed with the air in the second branch channel 1013. Finally, it is sent out from the first air outlet 1021 and the second air outlet 1022 respectively.

[0122] like Figure 5 and Figure 6As shown, in the second air supply state, the first air guide 21 covers the first air outlet 1021, and the second air guide 22 covers the second air outlet 1022. High-pressure zones are formed at the first branch channel 1012 and the second branch channel 1013. Part of the airflow entering the first branch channel 1012 can enter the ventilation cavity 1220 through the first vent 1061 and then exit through the multiple first air diffusers 1003 on the front panel 1002. Another part of the airflow can exit through the multiple second air diffusers 201 of the first air guide 21. Part of the airflow entering the second branch channel 1013 can enter the ventilation cavity 1220 through the second vent 1062 and then exit through the multiple first air diffusers 1003 on the front panel 1002. Another part of the airflow can exit through the multiple second air diffusers 201 of the second air guide 22, thereby achieving windless airflow from the first air outlet 1021, the second air outlet 1022, and the front panel 1002.

[0123] In the above technical solution, by defining the ventilation cavity 1220, when the air conditioner 100 is in the first air supply state, the hot or cold airflow outside the outer casing 10 can be effectively introduced into the first branch channel 1012 and the second branch channel 1013 through the ventilation cavity 1220 for mixing before being sent out. To a certain extent, this effectively fine-tunes the temperature and humidity of the airflow at the outlet, making the temperature and humidity of the airflow more comfortable. When the air conditioner 100 is in the second air supply state, each air guide covers the corresponding air outlet, allowing the airflow in each branch channel to be discharged to the external space through the multiple second air diffusers 201 of the corresponding air guide and the multiple first air diffusers 1003 on the front panel 1002. This effectively increases the airflow and cooling capacity without a draft, making the airflow softer and the wind feel better.
