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

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide an air conditioner whose airflow provides a more comfortable temperature and humidity, thus improving the user experience.

The front housing has an air outlet. The fan wheel is disposed inside the rear housing. An air duct is formed between the fan wheel and the air outlet. The front housing has at least one air passage that communicates with the external space of the front housing. The air passage is connected to the air duct through a connecting port. The connecting port has a first edge and a second edge that are disposed opposite to each other. The second edge is disposed closer to the air outlet than the first edge.

When high-speed flowing gas flows out of the air outlet, a local negative pressure zone can be formed in the air passage, allowing external air to be introduced into the air passage for mixing and finally sent out from the air outlet. This improves the mixing effect of the airflow to a certain extent, effectively fine-tunes the temperature and humidity of the airflow at the air outlet, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0051] The following is for reference. Figures 1-12 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0052] like Figures 1-7 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 an air outlet, and the number of air outlets can be one or more. The fan 60 is disposed inside the rear housing 1004, and an air duct 101 is provided between the fan 60 and the air outlet, that is, the air outlet is located in front of the fan 60.

[0053] The front shell 1001 has at least one air passage, which is connected to the external space of the front shell 1001. The air passage is connected to the air duct 101 through a connecting port. The connecting port has a first edge S1 and a second edge S2 that are arranged opposite to each other. The second edge S2 is closer to the air outlet than the first edge S1. The second edge S2 is located on the side of the air duct wall 1015 where the first edge S1 is located or the extension surface S3 of the air duct wall 1015 that is away from the air duct 101.

[0054] Wherein, the first edge S1 and the second edge S2 can be straight lines or curves. The extension surface S3 of the duct wall 1015 refers to the extension and stretching of the duct wall 1015, where the first edge S1 is located, following the original trend. The duct wall 1015, where the first edge S1 is located, can be a plane or a curved surface. In the embodiment where the duct wall 1015 is a plane, the extension surface S3 of the duct wall 1015 is located on the plane where the duct wall 1015 is located; in the embodiment where the duct wall 1015 is a curved surface, the extension surface S3 of the duct wall 1015 is extended and stretched according to the original trend of the curved surface.

[0055] like Figures 4-7 As shown, when the air outlet is open and the air conditioner 100 is in cooling mode, high-speed air flows out of the air outlet, which can form a local negative pressure zone in the air duct 101. At this time, the air passage can be used as an air intake passage. The air outside the outer casing 10 with a higher temperature can be introduced into the air duct 101 through the air passage and mixed with the air with a lower temperature in the air duct 101, and then sent out from the air outlet, and so on.

[0056] Therefore, by introducing external air, on the one hand, the outlet air temperature can be gradually reduced, avoiding discomfort caused by sudden changes in outlet air temperature; on the other hand, the hot air blown out of the outlet will not be too dry, but will have higher humidity, making the airflow softer and more comfortable.

[0057] like Figures 4-7 As shown, when the air outlet is open and the air conditioner 100 is in heating mode, high-speed air flows out of the air outlet, which can form a local negative pressure zone in the air duct 101. At this time, the air passage can be used as an air intake passage. The air outside the outer casing 10 with a lower temperature can be introduced into the air duct 101 through the air passage and mixed with the air with a higher temperature in the air duct 101 before being sent out from the air outlet, and so on.

[0058] Therefore, by introducing external air, on the one hand, the outlet air temperature 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 of the outlet is moderate.

[0059] like Figure 8 and Figure 9As shown, when the air outlet is covered, a high-pressure zone can be formed in the air duct 101. At this time, the air passage can be used as an exhaust passage, so that at least part of the airflow in the air duct 101 can be discharged from the air passage to the outside of the outer casing 10.

[0060] According to the embodiment of the present invention, the air conditioner 100, by setting an air passage and restricting the first edge S1 and the second edge S2 of the connecting port to meet the above conditions, creates a pressure difference in the area where the connecting port is located. When high-speed flowing gas flows out of the air outlet, a local negative pressure zone can be formed in the air passage 101, allowing air outside the outer casing 10 to be introduced into the air passage 101 for mixing and finally sent out from the air outlet. This improves the mixing effect of the airflow to a certain extent, effectively fine-tunes the airflow temperature and humidity at the air outlet, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0061] According to some embodiments of the present invention, there is one air passage, which can be located on one side of the air duct 101.

[0062] According to some other embodiments of the present invention, the number of air passages is at least two, including a first air passage 1031 and a second air passage 1032, that is, the front shell 1001 has a first air passage 1031 and a second air passage 1032. In the description of the present invention, "first feature" and "second feature" may include more than one of these features. The first air passage 1031 and the second air passage 1032 are connected to the external space of the front shell 1001. The connection port between the first air passage 1031 and the air duct 101 is a first connection port 1041, and the connection port between the second air passage 1032 and the air duct 101 is a second connection port 1042.

[0063] Each of the first connecting port 1041 and the second connecting port 1042 has a first edge S1 and a second edge S2 that are arranged opposite to each other. The second edge S2 is arranged closer to the air outlet than the first edge S1. The second edge S2 is located on the side of the air duct wall 1015 where the first edge S1 is located or the extension surface S3 of the air duct wall 1015 that is away from the air duct 101.

[0064] Specifically, for the first connecting port 1041, the second edge S2 of the first connecting port 1041 is located closer to the air outlet than the first edge S1 of the first connecting port 1041. The extension surface of the duct wall 1015 where the first edge S1 of the first connecting port 1041 is located is S3. The vertical distance between the second edge S2 of the first connecting port 1041 and the aforementioned extension surface S3 is L1, where L1 is greater than 0.

[0065] In other words, in the cross-section of the air conditioner 100, the intersection of the first edge S1 of the first connecting port 1041 and the plane of the cross-section is the first intersection point, the intersection of the second edge S2 of the first connecting port 1041 and the plane of the cross-section is the second intersection point, the intersection of the extension surface S3 and the plane of the cross-section can be a straight line or a curve, and the minimum distance from the second intersection point to the straight line or curve is the perpendicular distance L1 between the second edge S2 of the first connecting port 1041 and the extension surface S3.

[0066] In this way, the duct wall at the first edge S1 of the duct 101 can block the airflow in the first air passage 1031, allowing the airflow entering the duct 101 from the first air passage 1031 to flow towards the air outlet. Since the airflow at both the first air passage 1031 and the duct 101 flows towards the air outlet, a negative pressure zone is formed in the area where the first connecting port 1041 is located, further achieving air intake, and so on in a cycle.

[0067] Similarly, for the second connecting port 1042, the second edge S2 of the second connecting port 1042 is set closer to the air outlet than the first edge S1 of the second connecting port 1042. The extension surface of the duct wall 1015 where the first edge S1 of the second connecting port 1042 is located is S3. The vertical distance between the second edge S2 of the second connecting port 1042 and the aforementioned extension surface S3 is L2, and L2 is greater than 0.

[0068] In other words, in the cross-section of the air conditioner 100, the intersection of the first edge S1 of the second connecting port 1042 and the plane of the cross-section is the first intersection point, the intersection of the second edge S2 of the second connecting port 1042 and the plane of the cross-section is the second intersection point, the intersection of the extension surface S3 and the plane of the cross-section can be a straight line or a curve, and the minimum distance from the second intersection point to the straight line or curve is the perpendicular distance L2 between the second edge S2 of the second connecting port 1042 and the extension surface S3.

[0069] In this way, the duct wall at the first edge S1 of the duct 101 can block the airflow in the second air passage 1032, allowing the airflow entering the duct 101 from the second air passage 1032 to flow towards the air outlet. Since the airflow at both the second air passage 1032 and the duct 101 flows towards the air outlet, a negative pressure zone is formed in the area where the second connecting port 1042 is located, further achieving air intake, and so on in a cycle.

[0070] It should be noted that in the embodiment where the air conditioner 100 is a cabinet air conditioner 100, the first edge S1 and the second edge S2 both extend along the height direction of the air conditioner 100, and the cross-section of the air conditioner 100 is a section perpendicular to the height direction of the air conditioner 100, that is, the first edge S1 and the second edge S2 are perpendicular to the cross-section of the air conditioner 100; in the embodiment where the air conditioner 100 is a wall-mounted air conditioner 100, the first edge S1 and the second edge S2 both extend along the length direction of the air conditioner 100, and the cross-section of the air conditioner 100 is a section perpendicular to the length direction of the air conditioner 100, that is, the first edge S1 and the second edge S2 are perpendicular to the cross-section of the air conditioner 100.

[0071] like Figures 1-2 As shown, according to some embodiments of this utility model, the vertical distance between the second edge S2 and the duct wall 1015 or the extended surface S3 is greater than 3mm. If the vertical distance between the second edge S2 and the duct wall 1015 or the extended surface S3 is too small, sufficient external air cannot be introduced, resulting in an insignificant airflow effect.

[0072] In the above technical solution, by limiting the vertical distance between the second edge S2 and the duct wall 1015 or the extended surface S3 to meet the above conditions, the air passage can form an air intake passage when the air outlet is in the open state, so as to introduce sufficient external air into the air conditioner 100 to regulate the temperature and humidity of the air outlet airflow, and also to regulate the air volume of the air outlet.

[0073] It should be noted that when the duct wall 1015 is a curved surface, the vertical distance between the second edge S2 and the duct wall 1015 is the distance between the second edge S2 and the tangent surface of the duct wall 1015 at the first edge S1.

[0074] In some embodiments, at least one air passage is a first air passage 1031, and the connection between the first air passage 1031 and the air duct 101 is a first connection port 1041. The vertical distance L1 between the second edge S2 of the first connection port 1041 and the air duct wall 1015 or the extension surface S3 of the corresponding first edge S1 can be 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, etc.

[0075] In some embodiments, at least one air passage is a second air passage 1032, and the connection between the second air passage 1032 and the air duct 101 is a second connection port 1042. The perpendicular L2 between the second edge S2 of the second connection port 1042 and the corresponding first edge S1 of the air duct wall 1015 or the extension surface S3 of the air duct wall 1015 can be 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, etc.

[0076] If the vertical distance between the second edge S2 and the duct wall 1015 or the extension surface S3 of the duct wall 1015 where the first edge S1 is located is too large, meeting this distance will increase the size of the air conditioner 100, increase the materials used and the cost, and will also be detrimental to the miniaturization design of the air conditioner 100. Therefore, in some embodiments, the vertical distance between the second edge S2 and the duct wall 1015 or the extension surface S3 of the duct wall 1015 where the first edge S1 is located is less than or equal to 30mm.

[0077] like Figures 1-2 As shown, the distance between the projection of the second edge S2 onto the duct wall 1015 or the extended surface S3 and the first edge S1 is A. The distance A cannot be too large or too small, otherwise air leakage is likely to occur. In some embodiments, the distance A between the projection of the second edge S2 onto the duct wall 1015 or the extended surface S3 and the first edge S1 satisfies the condition: 1mm ≤ A ≤ 30mm. For example, the distance A between the projection of the second edge S2 onto the duct wall 1015 or the extended surface S3 and the first edge S1 can be 1mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, etc. This setting can reduce the occurrence of air leakage problems.

[0078] In some specific embodiments, 5mm≤A≤10mm can further reduce the occurrence of air leakage problems.

[0079] like Figures 1-2 As shown, according to some embodiments of the present invention, the second edge S2 is located on the side of the duct 101 away from the first edge S1. That is, the distance between the second edge S2 of the duct and the duct wall of the duct 101, which passes through the first edge S1 of the connecting opening, is greater than 0.

[0080] Therefore, by restricting the first edge S1 and the second edge S2 of the connection port to meet the above conditions, a pressure difference is formed in the area where the connection port is located. When high-speed flowing gas flows out of the air outlet, a local negative pressure zone can be formed in the air duct 101, so that the air outside the outer shell 10 can be introduced into the air duct 101 through the air passage for mixing, and finally sent out from the air outlet. This improves the mixing effect of the airflow to a certain extent, effectively fine-tunes the airflow temperature and humidity at the air outlet, making the temperature and humidity of the airflow more comfortable and improving the user experience.

[0081] In some embodiments, the distance between the second edge S2 and the cut surface is greater than 3 mm. If the distance between the second edge S2 and the cut surface is too small, insufficient external air cannot be introduced, resulting in an insignificant airflow effect.

[0082] In the above technical solution, by limiting the distance between the second edge S2 and the tangent to meet the above conditions, the air passage can form an air intake passage when the air outlet is in the open state, so as to introduce sufficient external air into the air conditioner 100 to regulate the temperature and humidity of the air outlet airflow, and also to regulate the air volume of the air outlet.

[0083] Specifically, the distance between the second edge S2 of the connecting port and the corresponding tangent can be 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, etc.

[0084] If the distance between the second edge S2 and the cut surface is too large, meeting this distance will increase the size of the air conditioner 100, increase the materials used and the cost, and will also be detrimental to the miniaturization design of the air conditioner 100. Therefore, in some embodiments, the distance between the second edge S2 and the cut surface is less than or equal to 30mm.

[0085] like Figures 1-2 As shown, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 cannot be too large or too small, otherwise air leakage is likely to occur. In some embodiments, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 is greater than 1 mm and less than 30 mm, or equal to 1 mm or equal to 30 mm. For example, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 can be 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, etc. This setting can reduce the occurrence of air leakage problems.

[0086] In some specific embodiments, the distance between the projection of the second edge S2 on the cut surface and the first edge S1 is greater than 5mm and less than 10mm, or equal to 5mm, or equal to 10mm, which can further reduce the occurrence of air leakage problems.

[0087] like Figure 1 As shown, in this embodiment, the number of air passages is at least two, including a first air passage 1031 and a second air passage 1032. The connection between the first air passage 1031 and the air duct 101 is a first connection port 1041, and the connection between the second air passage 1032 and the air duct 101 is a second connection port 1042.

[0088] The first air passage 1031 and the second air passage 1032 are located on opposite sides of the air duct 101, so that the first air passage 1031 and the second air passage 1032 are located on opposite sides of the air outlet, thereby forming the effect of central air outlet and side air intake or exhaust.

[0089] It should be noted that when the first air passage 1031 and the second air passage 1032 are asymmetrically arranged relative to the air duct 101, the distance L1 between the second edge S2 of the first connecting port 1041 and the corresponding first edge S1 on the air duct wall 1015 or the extension surface S3 of the air duct wall 1015, and the distance L2 between the second edge S2 of the second connecting port 1042 and the corresponding first edge S1 on the air duct wall 1015 or the extension surface S3 of the air duct wall 1015, can be unequal. The appropriate parameters can be selected according to the required air volume and other needs.

[0090] like Figures 1-3 , Figures 6-9 As shown, according to some embodiments of the present invention, the air conditioner 100 further includes a fan housing 13, an air outlet frame, and a heat exchanger 50. The fan housing 13 and the air outlet frame are both disposed inside the outer casing 10. The fan 60 is disposed inside the fan housing 13. The air outlet frame is located between the fan housing 13 and the air outlet. Different parts of the air outlet duct 101 are defined inside the fan housing 13 and the air outlet frame. The connecting port is disposed in the air outlet frame. The heat exchanger 50 is disposed between the air inlet 108 of the rear casing 1004 and the fan 60.

[0091] In some embodiments, at least one air passage is a first air passage 1031, and a sealing side plate 133 is connected between the heat exchanger 50 and the impeller housing 13. The air outlet frame, the heat exchanger 50, the impeller housing 13 and the sealing side plate 133 define the first air passage 1031.

[0092] In other embodiments, at least one air passage is a second air passage 1032, which is defined within the air outlet frame.

[0093] In some other embodiments, the number of air passages is at least two, including a first air passage 1031 and a second air passage 1032. A sealing side plate 133 is connected between the heat exchanger 50 and the impeller housing 13. The air outlet frame, the heat exchanger 50, the impeller housing 13 and the sealing side plate 133 define the first air passage 1031, and the air outlet frame defines the second air passage 1032.

[0094] In the above technical solution, by setting the impeller housing 13 and the air outlet frame inside the outer casing 10, the air outlet frame or the nearby structure can be used to define the air passage, which simplifies the structure of the air outlet frame, reduces the processing difficulty of the air outlet frame, and helps to improve production efficiency. Thus, the air passage can be used to realize air intake or exhaust.

[0095] like Figures 6-9As shown, in some embodiments, the air outlet frame includes a first frame 11 and a second frame 12. The two sides of the first frame 11 are connected to the impeller housing 13 and one side of the second frame 12, respectively. The other side of the second frame 12 is connected to the front shell 1001. The communication port 1042 is provided on the first frame 11.

[0096] In some examples, at least one air passage is a first air passage 1031, and a sealing side plate 133 is connected between the heat exchanger 50 and the impeller housing 13. The first frame 11, the second frame 12, the heat exchanger 50, the impeller housing 13 and the sealing side plate 133 define the first air passage 1031.

[0097] In other examples, at least one air passage is a second air passage 1032, which is defined within the first frame 11 and the second frame 12.

[0098] In some other examples, there are at least two air passages, namely a first air passage 1031 and a second air passage 1032. A sealing plate 133 is connected between the heat exchanger 50 and the impeller housing 13. The first frame 11, the second frame 12, the heat exchanger 50, the impeller housing 13 and the sealing plate 133 define the first air passage 1031, and the second air passage 1032 is defined within the first frame 11 and the second frame 12.

[0099] Therefore, by setting the air outlet frame to include a first frame 11 and a second frame 12 that are separately configured, and by combining multiple relatively simple structures to form a relatively complex structure and air passage, 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.

[0100] like Figures 10-12 As shown, the second frame 12 or the front shell 1001 has a positioning post 1211 and a first connecting hole 1212, and the first frame 11 has a positioning hole 114 and a second connecting hole 115. The positioning post 1211 is inserted into the positioning hole 114. 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 115, thereby ensuring the reliability of the connection between the second frame 12 or the front shell 1001 and the first frame 11.

[0101] Specifically, a plurality of mounting plates 116 are respectively provided on the right side of the first frame 11, and the plurality of mounting plates 116 are arranged in the length direction of the first frame 11 (e.g., ...). Figure 10As shown in the vertical direction, the mounting plates 116 are arranged at intervals. Each mounting plate 116 is provided with a positioning hole 114 and a second connecting hole 115. Correspondingly, the right side of the front shell 1001 is provided with multiple sets of positioning posts 1211 and first connecting holes 1212. The positioning holes 114 on the multiple mounting plates 116 are inserted into the multiple positioning posts 1211 in a one-to-one correspondence. The second connecting holes 115 on the multiple mounting plates 116 are positioned in a one-to-one correspondence with the multiple first connecting holes 1212. Thus, the front shell 1001 and the first frame 11 can be connected together by multiple fasteners to ensure the reliability of the connection between the front shell 1001 and the first frame 11.

[0102] Furthermore, the left side of the first frame 11 is provided with a plurality of positioning holes 114 and a plurality of second connecting holes 115, the number of positioning holes 114 and the number of second connecting holes 115 are equal, and the plurality of positioning holes 114 and the plurality of second connecting holes 115 are respectively provided along the length direction of the first frame 11 (e.g., ...). Figure 10 As shown in the vertical direction, multiple positioning holes 114 and multiple second connecting holes 115 are arranged at intervals, one-to-one correspondingly close to each other. Correspondingly, multiple positioning posts 1211 and multiple first connecting holes 1212 are respectively provided on the left side of the second frame 12. The multiple positioning holes 114 and multiple positioning posts 1211 are inserted and engaged one-to-one, and the multiple second connecting holes 115 and multiple first connecting holes 1212 are positioned one-to-one. Thus, the second frame 12 and the first frame 11 can be connected together by multiple fasteners, ensuring the reliability of the connection between the second frame 12 and the first frame 11.

[0103] like Figures 6-12 As shown, in some examples, at least two air passages include a first air passage 1031 and a second air passage 1032. The first frame 11 includes a first side plate 111 and a second side plate 112. The first side plate 111 and the second side plate 112 are arranged opposite to each other. Both sides of the first side plate 111 and the second side plate 112 are connected to one side of the impeller housing 13 and the second frame 12.

[0104] The connection between the first air passage 1031 and the air duct 101 is located on the first side plate 111, and the connection between the second air passage 1032 and the air duct 101 is located on the second side plate 112. Specifically, the connection between the first air passage 1031 and the air duct 101 is a first connection port 1041, and the connection between the second air passage 1032 and the air duct 101 is a second connection port 1042. The first connection port 1041 is located on the first side plate 111, and the second connection port 1042 is located on the second side plate 112.

[0105] Therefore, by setting the first frame 11 to the above structure, it is convenient to process a communication port including multiple through holes (e.g., elongated holes, round holes) on the first side plate 111 and the second side plate 112 respectively, which can prevent foreign objects from being drawn into the air duct 101, and can simplify the processing steps and improve production efficiency.

[0106] In some specific examples, the first frame 11 also includes a connecting plate 113, which is connected between the first side plate 111 and the second side plate 112, and defines a third communication port 1043, which connects two parts of the ventilation duct 101.

[0107] The first side plate 111 and the second side plate 112 are connected together by the connecting plate 113, so that the first frame 11 forms an integral structural component. On the one hand, this can improve the structural strength of the first frame 11, and on the other hand, it can make the first frame easier to install, which is conducive to improving the structural compactness and assembly efficiency of the air conditioner 100.

[0108] like Figures 10-12 As shown, in some specific examples, the second frame 12 is provided with two first baffles 1213 on the side facing the heat exchanger 50, and the two first baffles 1213 are in the length direction of the second frame 12 (e.g., Figure 10 The first air passage 1031 is arranged at intervals in the vertical direction shown, and the two first partitions 1213 abut against the heat exchanger 50 and the first side plate 111 to seal the first air passage 1031, ensuring the airtightness of the first air passage 1031, so that the first air passage 1031 can achieve normal switching between air intake and exhaust when the air outlet is opened and closed.

[0109] In some specific examples, the second frame 12 has two second partitions 1214 on the side facing the second side panel 112, and the two second partitions 1214 are located along the length of the second frame 12 (e.g., Figure 10 The second air passage 1032 is arranged at intervals in the vertical direction shown, and the two second partitions 1214 abut against the second side plate 112 to seal the second air passage 1032, ensuring the airtightness of the second air passage 1032, so that the second air passage 1032 can achieve normal switching between air intake and exhaust when the air outlet is opened and closed.

[0110] like Figure 1 and Figure 2 , Figure 7 and Figure 9As shown, in some embodiments, the air duct 101 includes a main channel 1011, a first branch channel 1012 and a second branch channel 1013, and at least two air outlets, namely a first air outlet 1021 and a second air outlet 1022. The first branch channel 1012 connects the first air outlet 1021 and the main channel 1011, and the second branch channel 1013 connects the second air outlet 1022 and the main channel 1011.

[0111] The first frame 11 defines the main channel 1011, and 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.

[0112] Specifically, when the first air outlet 1021 and the second air outlet 1022 are open, air outside the outer casing 10 can enter the air duct 101 through the air passage to mix with the airflow inside the air duct 101, and finally be discharged from the first air outlet 1021 and the second air outlet 1022. When the first air outlet 1021 and the second air outlet 1022 are covered, at least a portion of the airflow inside the air duct 101 is discharged to the outside of the outer casing 10 through the air passage.

[0113] In the above technical solution, by setting a first air outlet 1021, a second air outlet 1022, and an air passage, multiple air outlets can be used to output air. Furthermore, the air passage can improve the mixing effect of the airflow in the first branch passage 1012 and the second branch passage 1013, effectively fine-tuning 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.

[0114] like Figures 1-3 As shown, in some examples, the impeller housing 13 includes a volute 132 and a volute tongue 131 disposed opposite to each other. Both the volute 132 and the volute tongue 131 are connected to the first frame 11. In the airflow direction, the end of the volute tongue 131 near the first frame 11 is located downstream of the end of the volute 132 near the first frame 11.

[0115] In some specific examples, at least one air passage is a first air passage 1031, the connection between the first air passage 1031 and the air duct 101 is a first connection port 1041, the first connection port 1041 and the volute tongue 131 are located on the same side of the air duct wall of the air duct 101, and the first connection port 1041 is arranged facing the first branch passage 1012.

[0116] In some other specific examples, at least one air passage is a second air passage 1032, and the connection between the second air passage 1032 and the air duct 101 is a second connection port 1042, which is oriented toward the main passage 1011.

[0117] In some specific examples, the number of air passages is at least two, including a first air passage 1031 and a second air passage 1032. The connection between the first air passage 1031 and the air duct 101 is a first connection port 1041. The first connection port 1041 and the volute tongue 131 are located on the same side of the air duct wall of the air duct 101, and the first connection port 1041 is arranged facing the first branch passage 1012. At least one air passage is a second air passage 1032. The connection between the second air passage 1032 and the air duct 101 is a second connection port 1042, and the second connection port 1042 is arranged facing the main passage 1011.

[0118] When the first air outlet 1021 and the second air outlet 1022 are open, the air outside the outer casing 10 can flow along the first air passage 1031 into the first branch passage 1012, thereby mixing with the gas in the first branch passage 1012, and finally being discharged from the first air outlet 1021. The air outside the outer casing 10 can also flow along the second air passage 1032 into the main passage 1011, thereby mixing with the gas in the main passage 1011. Then, part of the airflow flows along the first branch passage 1012 and is finally discharged from the first air outlet 1021, while the other part of the airflow flows along the second branch passage 1013 and is finally discharged from the second air outlet 1022.

[0119] When the first air outlet 1021 and the second air outlet 1022 are covered, at least a portion of the airflow in the main channel 1011 is discharged to the outside of the outer casing 10 through the first air passage 1031 and the second air passage 1032, respectively.

[0120] Since one end of the first frame 11 is connected to the volute tongue 131, the first connecting port 1041 and the volute tongue 131 are located on the same side of the air duct wall of the air duct 101, and the first connecting port 1041 is set towards the first branch channel 1012, the airflow speed and air volume of the first branch channel 1012 are relatively large. The air outside the outer shell 10 can be directly introduced into the first branch channel 1012 through the first air passage 1031, which can further improve the mixing effect of the airflow in the first branch channel 1012, and more effectively fine-tune the airflow temperature and humidity of the first air outlet 1021, so that the temperature and humidity of the airflow from the first air outlet 1021 and the second air outlet 1022 are more uniform and comfortable.

[0121] In addition, the first connecting port 1041 is positioned toward the first branch channel 1012, so that the first connecting port 1041 is located at the other end of the first frame 11 away from the volute tongue 131, which can ensure the structural strength of the first frame 11.

[0122] like Figure 7 and Figure 9 As shown, in some examples, the front housing 1001 includes a front panel 1002, which is located on the side of the partition 122 facing away from the main channel 1011, and the first air outlet 1021 and the second air outlet 1022 are located on both sides of the front panel 1002.

[0123] In the above technical solution, by setting the front panel 1002 on the side of the partition 122 facing away from the main channel 1011, the front panel 1002 can cover the partition 122, ensuring that the appearance of the air conditioner 100 is flatter and more beautiful, which is conducive to improving the visual experience.

[0124] In some specific examples, a ventilation cavity 1220 is defined between the front panel 1002 and the partition 122. The ventilation cavity 1220 connects to each of the first branch channel 1012 and the second branch channel 1013. The front panel 1002 is provided with a plurality of first ventilation holes 1003, which connect the ventilation cavity 1220 and the external space.

[0125] 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 local 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, so that the warmer air outside the outer casing 10 can also enter the ventilation cavity 1220 from the multiple first air diffusers 1003, thereby introducing it into the first branch channel 1012 and the second branch channel 1013, and mixing it with the cooler air in the first branch channel 1012 and the second branch channel 1013, and then sending it out from the first air outlet 1021 and the second air outlet 1022 respectively, and so on.

[0126] 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 local 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, so that the cooler air outside the outer casing 10 can also enter the ventilation cavity 1220 from the multiple first air diffusers 1003, thereby introducing it into the first branch channel 1012 and the second branch channel 1013, and mixing it with the warmer air in the first branch channel 1012 and the second branch channel 1013, and then sending it out from the first air outlet 1021 and the second air outlet 1022 respectively, and so on.

[0127] Therefore, by defining the ventilation cavity 1220 between the partition 122 and the front panel 1002, the number of channels for introducing external air can be increased, thereby increasing the air volume and further improving the airflow mixing effect. This 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.

[0128] 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, so that at least a part of the airflow in the first branch channel 1012 and the second branch channel 1013 can enter the ventilation cavity 1220 and finally be discharged to the outside of the outer casing 10 through multiple first air diffusers 1003.

[0129] Therefore, by defining the ventilation cavity 1220 between the partition 122 and the front panel 1002, the number of channels for exhausting internal air can be increased, thereby increasing the exhaust volume and meeting the user's needs.

[0130] The multiple first ventilation holes 1003 on the front panel 1002 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.

[0131] 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.

[0132] like Figure 7 and Figure 9As shown, in some specific examples, the partition 122 includes a first guide vane 1221 and a second guide vane 1222. The first guide vane 1221 and the second guide vane 1222 are arranged at an angle, and the first guide vane 1221 and the second guide vane 1222 extend away from each other along the air outlet direction. The first guide vane 1221 forms part of the wall of the first branch channel 1012, and the second guide vane 1222 forms part of the wall of the second branch channel 1013.

[0133] The front panel 1002 is connected to the first guide plate 1221 and the second guide plate 1222 at both ends. The first guide plate 1221 is provided with a first vent 1061, and the first vent 1061 connects the ventilation cavity 1220 and the first branch channel 1012. The second guide plate 1222 is provided with a second vent 1062, and the second vent 1062 connects the ventilation cavity 1220 and the second branch channel 1013.

[0134] 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.

[0135] 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, the air outside the outer casing 10 can enter the ventilation cavity 1220, and then enter the first branch channel 1012 through the first vent 1061, and enter the second branch channel 1013 through the second vent 1062, and finally be discharged through the first air outlet 1021 and the second air outlet 1022. 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.

[0136] like Figure 2 , Figure 7 and Figure 9 As shown, in some examples, the air conditioner 100 also includes a diverter 124, which is disposed on the side of the partition 122 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.

[0137] The diverter 124 has a first diverting surface 1241 and a second diverting surface 1242, which are arranged opposite to each other. 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.

[0138] In the above technical solution, by setting a diverter 124 on the side of the partition 122 away from the front panel 1002, the diverter 124 can correct the diversion effect of the partition 122, 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.

[0139] 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.

[0140] like Figure 2 As shown, in order to ensure the diversion effect of the diversion component 124 and reduce air volume loss, the included angle between the tangents of the first diversion surface 1241 and the second diversion surface 1242 at the connection is an acute angle. For example, the included angle γ between the tangents of the first diversion surface 1241 and the second diversion surface 1242 at the connection can be less than or equal to 30°.

[0141] The first diversion surface 1241 is located upstream of the first vent 1061 in the airflow direction, and the second diversion surface 1242 is located upstream of the second vent 1062 in the airflow direction.

[0142] 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.

[0143] 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 outside of the outer casing 10 from the first diffuser hole 1003. Another portion of the airflow flows to the outside of the outer casing 10 from the first air passage 1031. 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 outside of the outer casing 10 from the first diffuser hole 1003. Another portion of the airflow flows to the outside of the outer casing 10 from the second air passage 1032.

[0144] like Figures 10-12 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.

[0145] 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.

[0146] like Figure 1 As shown, in some embodiments, 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, and the extension directions of the first air passage 1031 and the second air passage 1032 are not equal to the angles with the center line P.

[0147] 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.

[0148] 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.

[0149] Furthermore, the first air outlet 1021 and the second air outlet 1022 are symmetrically arranged about the center line P. The first air passage 1031 and the external space of the outer shell 10 are connected through the first air passage 1051, and the second air passage 1032 and the external space of the outer shell 10 are connected through the second air passage 1052. The first air passage 1051 and the second air passage 1052 are symmetrically arranged about the center line P.

[0150] Since the first air outlet 1021 and the second air outlet 1022, the first air vent 1051 and the second air vent 1052 are exposed on the outside of the outer casing 10, they serve as the appearance structure of the air conditioner 100. By defining the first air outlet 1021 and the second air outlet 1022, the first air vent 1051 and the second air vent 1052 as symmetrically arranged about the center line P, the appearance of the air conditioner 100 is symmetrical, which is beneficial to improving the visual experience.

[0151] like Figures 4-6 , Figure 8 , Figures 10-12 As shown, a first air vent 1051 and a second air vent 1052 are disposed on the front housing 1001. The first air vent 1051 and the second air vent 1052 can be defined by a grille structure, so that both the first air vent 1051 and the second air vent 1052 are constructed to include multiple elongated holes. For example, the multiple elongated holes are arranged in a manner similar to... Figures 4-6 The front shell 1001 is arranged along its height. Of course, the first air vent 1051 and the second air vent 1052 may also each include multiple circular hole structures.

[0152] Therefore, by setting the first air vent 1051 and the second air vent 1052 into the above structure, on the one hand, the structural strength of the front shell 1001 can be guaranteed, and on the other hand, the grille structure can be used to construct each air vent to include multiple through holes (e.g., elongated holes), which can prevent foreign objects from being drawn into the corresponding air vents and also prevent fingers from being inserted into the air conditioner 100, thus ensuring the user's safety.

[0153] like Figure 3 As shown, according to some embodiments of the present invention, at least two air passages include a first air passage 1031 and a second air passage 1032. The first air passage 1031 and the second air passage 1032 are located on opposite sides of the air duct 101. The connection between the first air passage 1031 and the air duct 101 is a first connection port 1041, and the connection between the second air passage 1032 and the air duct 101 is a second connection port 1042.

[0154] The distance between the first edge S1 of the first connecting port 1041 and the first edge S1 of the second connecting port 1042 is m, and the distance between the second edge S2 of the first connecting port 1041 and the second edge S2 of the second connecting port 1042 is n, where m is less than n.

[0155] This configuration allows for a higher air pressure upstream of the first connecting port 1041 and the second connecting port 1042 in the extension direction of the air duct 101, and a lower air pressure downstream of the first connecting port 1041 and the second connecting port 1042. This allows air outside the outer casing 10 to enter the air duct 101 through the first air passage 1031 and the second air passage 1032 under the action of pressure difference, resulting in a better air intake effect.

[0156] In some embodiments, at least a portion of the air duct 101 is a gradually expanding section 1014 with a flow area that gradually increases along the air outlet direction, and the first connecting port 1041 and the second connecting port 1042 are both opened on the wall of the gradually expanding section 1014.

[0157] Therefore, by opening the wall of the gradually expanding section 1014 of the air duct 101 through the first connecting port 1041 and the second connecting port 1042, the air outside the outer shell 10 can be effectively introduced into the air duct 101 through the first air passage 1031 and the second air passage 1032 for mixing. To a certain extent, this effectively fine-tunes the temperature and humidity of the airflow from the first air outlet 1021 and the second air outlet 1022, making the temperature and humidity of the airflow more comfortable, gentler, and with a better wind feel.

[0158] According to some embodiments of the present invention, the air conditioner 100 further includes an air guide assembly 20, which includes a movable air guide for covering or opening the air outlet, and the air guide is provided with a plurality of second air dissipation holes 201.

[0159] The air conditioner 100 has a first air supply state and a second air supply state.

[0160] In the first air supply state, the air guide opens the air outlet to form an air intake channel. In this state, the air guide opens the air outlet, and high-speed air flows out, creating a local negative pressure zone within the air duct 101. Air from outside the casing 10 is introduced into the air duct 101 through the air intake channel, mixes with the air inside the air duct 101, and is finally discharged from the air outlet. By introducing external air, the outlet air temperature gradually changes, avoiding discomfort caused by sudden temperature changes, and the humidity of the air blown out from the outlet is kept moderate.

[0161] In the second air supply state, the air guide covers the corresponding air outlet to form an exhaust channel. In this state, the air guide covering the air outlet can create a high-pressure zone within the air duct 101. Part of the airflow within the air duct 101 can be exhausted to the outside of the outer casing 10 through the air passage, while another part of the airflow can be discharged through the multiple second air diffusers 201 of the air guide. This effectively improves the airflow volume and cooling capacity, eliminating the feeling of draft.

[0162] 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 air guide to swing periodically. During the swing of the air guide, the positive and negative pressure in the air duct 101 switches, so that the air passage 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.

[0163] 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.

[0164] like Figures 1-2 , Figures 4-9 As shown, in this embodiment, there are two air outlets, namely the first air outlet 1021 and the second air outlet 1022, and two air guides, namely the first air guide 21 and the second air guide 22. The first air guide 21 and the second air guide 22 are used to cover or open the first air outlet 1021 and the second air outlet 1022 respectively. The first air guide 21 and the second air guide 22 are each provided with a plurality of second air diffusers 201. At least two air passages include a first air passage 1031 and a second air passage 1032, and the first air passage 1031 and the second air passage 1032 are located on both sides of the air duct 101.

[0165] The air conditioner 100 has a first air supply state and a second air supply state.

[0166] like Figure 7 As shown, 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 first air passage 1031 and the second air passage 1032 form an air intake passage.

[0167] 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 air flows out from the first air outlet 1021 and the second air outlet 1022, which can respectively form local negative pressure zones at the first branch channel 1012 and the second branch channel 1013. Air outside the outer casing 10 can be introduced into the air duct 101 through the first air passage 1031 and the second air passage 1032, and interact with the air in the air duct 101. In the secondary mixing process, air from outside the outer casing 10 can also enter the ventilation cavity 1220 through multiple first air diffusers 1003 on the front panel 1002, then enter the first branch channel 1012 through the first vent 1061, where it undergoes a second mixing with the air inside the first branch channel 1012. It then enters the second branch channel 1013 through the second vent 1062, where it undergoes a second mixing with the air inside the second branch channel 1013, and finally exits from the first air outlet 1021 and the second air outlet 1022. By introducing external air, the outlet air temperature of the first air outlet 1021 and the second air outlet 1022 gradually changes, avoiding discomfort caused by sudden temperature changes. Furthermore, the humidity of the air blown out from the first air outlet 1021 and the second air outlet 1022 is kept at a moderate level.

[0168] like Figure 9 As shown, 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 first air passage 1031 and the second air passage 1032 form an exhaust passage.

[0169] 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, at least a portion of the airflow in the air duct 101 can be discharged to the outside of the outer casing 10 from the first air passage 1031 and the second air passage 1032 respectively, a portion of the airflow entering the first branch channel 1012 can enter the ventilation cavity 1220 from the first vent 1061, and then be discharged from the multiple first air diffusers 1003 on the front panel 1002, another portion of the airflow can be discharged from 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 from the second vent 1062, and then be discharged from the multiple first air diffusers 1003 on the front panel 1002, another portion of the airflow can be discharged from the multiple second air diffusers 201 of the second air guide 22. This allows airflow to be discharged from the multiple first air vents 1003 on the front panel 1002, the multiple second air vents 201 on the first air guide 21 and the second air guide 22, the first air passage 1031 and the second air passage 1032, effectively increasing the airflow and cooling capacity without a draft.

[0170] In some embodiments, the air conditioner 100 further includes a door opening and closing assembly 30, which includes a door for opening and closing air outlets. In a first air supply state and a second air supply state, the door opens the corresponding air outlet.

[0171] like Figures 1-2 , Figures 4-9 As shown, in this embodiment, there are two air outlets, namely the first air outlet 1021 and the second air outlet 1022, and two switch doors, namely the first switch door 31 and the second switch door 32. The first switch door 31 and the second switch door 32 are used to open and close the first air outlet 1021 and the second air outlet 1022, respectively. In the first air supply state and the second air supply state, the first switch door 31 and the second switch door 32 open the corresponding air outlets.

[0172] Specifically, when the air conditioner 100 is off, the first door 31 can be controlled to close the first air outlet 1021, and the second door 32 can be controlled to close the second air outlet 1022, preventing dust from entering the outer casing 10 through the first air outlet 1021 and the second air outlet 1022. When the air conditioner 100 is working, the first door 31 can be controlled to open the first air outlet 1021, and the second door 32 can be controlled to open the second air outlet 1022.

[0173] Therefore, by setting up movable first and second doors 31 and 32, and utilizing the relatively simple structure and low cost of the first and second doors 31 and 32, the corresponding air outlets can be opened and closed. The position states of the first air guide 21 and the second air guide 22 can be combined to create a variety of air supply states, thereby increasing the functionality of the air conditioner 100 and meeting different usage needs.

[0174] Understandably, the air pressure at the first branch channel 1012 and the second branch channel 1013 can be adjusted by controlling the opening of the first and second opening doors 31 and 32, the first air guide 21 and the second air guide 22, thereby changing the air intake or exhaust volume of the first and second air passages 1031 and 1032, and the air output volume of the first and second air outlets 1021 and 1022. This achieves multi-directional air output and multi-area cooling or heat dissipation, improving the air output effect and user experience. Of course, the air supply direction can also be changed by controlling the sway blade assembly 40; for example, multiple sway blades 42 can swing up and down.

[0175] 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.

[0195] When the air conditioner 100 is working, the fan wheel 60 can drive the air outside the casing 10 to flow through the air inlet 108 and 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.

[0196] The air conditioner 100 has at least an off state, a first air supply state, and a second air supply state.

[0198] like Figure 7As shown, in the first air supply state, both the first switch door 31 and the second switch door 32 are in the open position. 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 air flows out from the first air outlet 1021 and the second air outlet 1022, which can respectively form local negative pressure zones at the first branch channel 1012 and the second branch channel 1013. Air from outside the outer casing 10 can be introduced into the air duct 101 through the first air passage 1031 and the second air passage 1032, and mix with the air. The air inside the duct 101 is mixed for the first time. The air outside the outer casing 10 can also enter the ventilation cavity 1220 through multiple first air diffusers 1003 on the front panel 1002. Then, it is introduced into the first branch channel 1012 through the first vent 1061 and mixed with the air in the first branch channel 1012 for the second time. It is then introduced into the second branch channel 1013 through the second vent 1062 and mixed with the air in the second branch channel 1013 for the second time. Finally, it is sent out from the first air outlet 1021 and the second air outlet 1022 respectively.

[0199] like Figure 9 As shown, in the second air supply state, both the first switch door 31 and the second switch door 32 are in the open position. 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, respectively. At least a portion of the airflow in the duct 101 can be discharged to the outside of the outer casing 10 through the first air passage 1031 and the second air passage 1032. A portion of the airflow entering the first branch channel 1012 can enter the ventilation cavity 1220 through the first vent 1061. The airflow is discharged from the multiple first air diffusers 1003 on the front panel 1002, and another part of the airflow can be discharged from the multiple second air diffusers 201 on the first air guide 21. A part of the airflow entering the second branch channel 1013 can enter the ventilation cavity 1220 from the second vent 1062 and then be discharged from the multiple first air diffusers 1003 on the front panel 1002. Another part of the airflow can be discharged from the multiple second air diffusers 201 on the second air guide 22, thereby enabling the first air outlet 1021, the second air outlet 1022 and the front panel 1002 to achieve windless airflow.

[0200] In the above technical solution, by defining the first air passage 1031 and the second air passage 1032, when the air conditioner 100 is in the first air supply state, it can effectively introduce the hot or cold airflow outside the outer casing 10 into the air duct 101 for mixing before sending it out. To a certain extent, it 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, so that the airflow in each branch channel can be discharged to the outside of the outer casing 10 through the multiple second air diffusers 201 of the corresponding air guide, the first air passage 1031, the second air passage 1032, 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.
