[0045] 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 intended to explain this utility model, and should not be construed as limiting this utility model.

[0046] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0047] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0048] According to the embodiment of the present utility model, the air conditioner 100, such as Figure 1 and Figure 2As shown, the air conditioner 100 includes: a housing component 10 and a ventilation and heat exchange component 30. The length direction of the housing component 10 is vertical. The ventilation and heat exchange component 30 is disposed inside the housing component 10 and includes a fan component 4 and a heat exchange component 5 arranged in the horizontal direction. The air inlet 101 of the air conditioner 100 is disposed near the heat exchange component 5 relative to the fan component 4, and the air outlet 102 of the air conditioner 100 is disposed near the fan component 4 relative to the heat exchange component 5. The housing component 10 includes a rear panel 1 located behind the ventilation and heat exchange component 30. The heat exchange component 5 is assembled and connected to the rear panel 1, the fan component 4 is assembled and connected to the rear panel 1, and the heat exchange component 5 is assembled and connected to the fan component 4.

[0049] The housing component 10 is the outer contour of the air conditioner 100, and the length direction of the air conditioner 100 is the vertical direction; the ventilation and heat exchange component 30 includes a fan component 4 and a heat exchange component 5. The fan component 4 is used to provide flowing airflow, and the heat exchange component 5 is used to exchange heat with the flowing airflow. The ventilation and heat exchange component 30 generates flowing heat exchange airflow and sends it out of the air conditioner 100 to regulate the indoor temperature.

[0050] By arranging the fan component 4 and the heat exchange component 5 in the left-right direction, the size of the ventilation and heat exchange component 30 in the front-back direction can be reduced, thus reducing the space occupied in the front-back direction. This makes the structure of the fan component 4 and the heat exchange component 5 compact, resulting in a smaller air conditioner 100 and a smaller installation footprint.

[0051] Furthermore, the positions of the air outlet 102 and air inlet 101 of the air conditioner 100 are coordinated with the arrangement of the fan component 4 and the heat exchange component 5, reducing the space occupied by the ventilation and heat exchange component 30 in the front-to-back direction without affecting the normal ventilation and heat exchange effect. The air inlet 101 is positioned closer to the heat exchange component 5 relative to the fan component 4, and the air outlet 102 is positioned closer to the fan component 4 relative to the heat exchange component 5. The air entering the air conditioner 100 first undergoes heat exchange through the heat exchange component 5, and then is sent out from the air outlet 102 under the action of the fan component 4.

[0052] Furthermore, both the fan component 4 and the heat exchange component 5 are mounted on the rear panel 1, facilitating the assembly of the air conditioner 100. For example, the fan component 4 and the heat exchange component 5 can be mounted on the rear panel 1 before being assembled with the other parts of the air conditioner 100. Moreover, not only are the fan component 4 and the heat exchange component 5 connected to the rear panel 1, but the fan component 4 is also assembled and connected to the heat exchange component 5, which improves the connection stability of the fan component 4 and the heat exchange component 5, further enhancing the overall connection stability and reliability of the fan component 4, the heat exchange component 5, and the rear panel 1.

[0053] According to the embodiment of the present utility model, the air conditioner 100 has a compact structure by arranging the fan component 4 and the heat exchange component 5 in the left-right direction, which helps to reduce the size in the front-back direction and facilitates the connection and assembly of the two. By installing both the fan component 4 and the heat exchange component 5 on the rear panel 1, it is easy to assemble. Furthermore, the heat exchange component 5 and the fan component 4 are also connected, which can improve the overall connection stability and reliability, and thus improve the working reliability of the air conditioner 100.

[0054] In some embodiments of this utility model, such as Figure 2 As shown, the fan component 4 includes a vertically oriented cross-flow impeller 41, and the heat exchange component 5 includes a heat exchanger 51. The end of the heat exchanger 51 furthest from the fan component 4 in the left-right direction is the distal end 51a. The heat exchanger 51 includes a rear extension 511 and a front extension 512. The rear extension 511 extends from the distal end 51a to the rear of the cross-flow impeller 41, and the front extension 512 extends from the distal end 51a to the front of the cross-flow impeller 41.

[0055] The heat exchange component 5 and the fan component 4 are arranged in a left-right direction. The end of the heat exchanger 51 furthest from the fan component 4 in the left-right direction is the distal end 51a. The heat exchanger 51 also includes a front extension 512 and a rear extension 511. The front extension 512 of the heat exchanger 51 extends from the rear to the front from the distal end 51a toward the direction closer to the fan component 4, and the rear extension 511 of the heat exchanger 51 extends from the front to the rear from the distal end 51a toward the direction closer to the fan component 4. Compared with arranging the heat exchanger 51 in a straight line along the front-back direction, by providing the front extension 512 and the rear extension 511, the extension size of the heat exchanger 51 can be increased, the heat exchange area of ​​the heat exchanger 51 can be increased, which is beneficial to improving the heat exchange efficiency of the airflow.

[0056] It is worth noting that the extension 512 extending to the front of the cross-flow impeller 41 means that the extension 512 is at least partially located in front of the axis of the cross-flow impeller 41. The end of the extension 512 is not directly opposite to the axis of the cross-flow impeller 41 in the front-rear direction, but extends beyond the axis of the cross-flow impeller 41 in the front-rear direction. Similarly, the extension 511 extending to the rear of the cross-flow impeller 41 means that the extension 511 is at least partially located behind the axis of the cross-flow impeller 41. The end of the extension 511 is not directly opposite to the axis of the cross-flow impeller 41 in the front-rear direction, but extends beyond the axis of the cross-flow impeller 41 in the front-rear direction. The heat exchanger 51 occupies less space in the front and rear directions of the cross-flow fan 41, making the structure of the heat exchanger 51 and the cross-flow fan 41 compact. The air conditioner 100 has a small body and a small installation area. In addition, the cross-flow fan 41 has space in the front and rear directions, which is conducive to increasing the size of the cross-flow fan 41, thereby improving the air supply effect of the air conditioner 100.

[0057] In some embodiments of this utility model, such as Figure 2 As shown, on the horizontal cross-section of the air conditioner 100, the included angle A between the rear extension 511 and the front extension 512 is 25°-60°, and the line X connecting the rear end of the rear extension 511 and the front end of the front extension 512 passes through the cross-flow fan 41.

[0058] Understandably, the air inlet 101 of the air conditioner 100 is positioned close to the heat exchange component 5 relative to the fan component 4. At least part of the air intake of the air conditioner 100 flows in the left-right direction. When the angle between the rear extension 511 and the front extension 512 is too small, the size of the heat exchanger 51 in the front-back direction is too small, reducing the airflow heat exchange area and lowering the heat exchange efficiency. Conversely, when the angle between the rear extension 511 and the front extension 512 is too large, the size of the heat exchanger 51 in the front-back direction is too large, increasing its space occupation in that direction. Furthermore, the heat exchanger 51 tends to resemble a flat plate extending in the front-back direction, reducing its heat exchange area and also affecting its heat exchange efficiency.

[0059] Therefore, in some embodiments of this utility model, the included angle A between the rear extension 511 and the front extension 512 is limited to 25°-60°, which can increase the heat exchange area, improve the heat exchange efficiency, and help save space in the front-to-back direction, thereby reducing the size of the whole unit in the front-to-back direction and reducing the floor space of the air conditioner 100.

[0060] Optionally, the included angle A between the rear extension 511 and the front extension 512 is 25°, 30°, 45°, 50° or 60°.

[0061] The line X connecting the rear end of the rear extension 511 and the front end of the front extension 512 passes through the cross-flow fan 41. The heat exchanger 51 and the cross-flow fan 41 are relatively close in the left and right directions, which makes the structure of the heat exchange component 5 and the ventilation component compact. This helps to reduce the size of the whole unit in the left and right directions and reduce the floor space of the air conditioner 100.

[0062] In some embodiments of this utility model, such as Figures 3-5 As shown, the rear panel 1 is constructed to extend forward at both ends on the left and right. A receiving cavity 1a is formed between the heat exchange component 5 and the rear panel 1. A clearance opening 11 that communicates with the receiving cavity 1a is defined between the heat exchange component 5 and the rear panel 1. At least a portion of the fan component 4 is disposed in the receiving cavity 1a. The fan component 4 is connected to the air outlet 102 through the air outlet section 6 that passes through the clearance opening 11. The size of the clearance opening 11 is configured such that the portion of the fan component 4 disposed in the receiving cavity 1a cannot enter or exit the receiving cavity 1a through the clearance opening 11.

[0063] After the heat exchange component 5 is assembled and connected to the rear panel 1, a receiving cavity 1a is formed between the heat exchange component 5 and the rear panel 1. At least part of the fan component 4 is disposed in the receiving cavity 1a. The heat exchange component 5 and the fan component 4 have a compact structure, which is conducive to reducing the overall size of the air conditioner 100 and reducing the floor space occupied by the air conditioner 100.

[0064] The outline edge of the heat exchanger 51 forms a clearance opening 11 with the rear panel 1, communicating with the receiving cavity 1a. The fan component 4 passes through the clearance opening 11 via the air outlet section 6. The air outlet section 6 can be a component independent of the fan component 4, or it can be a part of the fan component 4. The clearance opening 11 is small in size, so that the part of the fan component 4 located in the receiving cavity 1a cannot enter or exit the receiving cavity 1a through the clearance opening 11. Therefore, in some embodiments of this utility model, the fan component 4 is first assembled and connected to the rear panel 1, and then the heat exchange component 5 is assembled and connected to the rear panel 1, or the fan component 4 and the heat exchange component 5 are first connected as a whole, and then assembled and connected to the rear panel 1, thereby completing the assembly.

[0065] In some embodiments of this utility model, such as Figure 2 As shown, the housing component 10 has a front-to-back dimension equal to the thickness L of the air conditioner 100, and a left-to-right dimension equal to the width W of the air conditioner 100. The width W of the air conditioner 100 is greater than the thickness L of the air conditioner 100.

[0066] By designing the housing component 10 such that its dimension L in the front-to-back direction is smaller than its dimension in the left-to-right direction, the size in the front-to-back direction can be reduced, thereby reducing the space occupied in the front-to-back direction and facilitating the arrangement of the air conditioner 100.

[0067] In some embodiments of this utility model, such as Figure 2 As shown, the fan component 4 includes a vertically oriented cross-flow fan 41, the ratio of the diameter D of the cross-flow fan 41 to the thickness L of the air conditioner 100 is greater than or equal to 0.4; and / or, the thickness L of the air conditioner 100 is less than or equal to 320 mm.

[0068] By setting the ratio of the diameter D of the cross-flow fan 41 to the thickness L of the air conditioner 100 to be greater than or equal to 0.4, the diameter D of the cross-flow fan 41 is made relatively large, which can improve the air delivery effect of the air conditioner 100 and help the thin air conditioner 100 achieve a large air volume effect. For example, the ratio of the diameter D of the cross-flow fan 41 to the thickness L of the air conditioner 100 can be 0.4, 0.5, 0.6, 0.65, 0.7, 0.75, etc.

[0069] By setting the thickness L of the air conditioner 100 to be less than or equal to 320mm, the air conditioner 100 has a thin body, a small installation footprint, can adapt to more installation environments, and also ensures the stability of performance after installation. For example, the thickness L of the air conditioner 100 can be 320mm, 315mm, 310mm, 305mm, 300mm, etc.

[0070] By arranging the fan component 4 and the heat exchange component 5 in the left-right direction, and setting the thickness L of the air conditioner 100 to be less than or equal to 320mm, the structure of the fan component 4 and the heat exchange component 5 is compact, the air conditioner 100 body is thin, and the installation area is small. By setting the ratio of the diameter D of the cross-flow fan wheel 41 to the thickness L of the air conditioner 100 to be greater than or equal to 0.4, it is beneficial to increase the size of the cross-flow fan wheel 41, which can improve the air delivery effect of the air conditioner 100 and help to achieve a large air volume effect in the thin air conditioner 100.

[0071] In some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the housing component 10 also includes a front panel 2, which is mounted on the front side of the rear panel 1. The front panel 2 is formed to extend rearward at both ends. The dimensions of the front panel 2 in the front-rear direction and the dimensions of the rear panel 1 in the front-rear direction are each greater than 1 / 3 of the dimensions of the housing component 10 in the front-rear direction.

[0072] The housing component 10 includes a front panel 2 and a rear panel 1. The structure of the housing component 10 is simple, which facilitates the assembly of the air conditioner 100. Furthermore, the front panel 2 is larger than 1 / 3 of the housing component 10 in the front-rear direction, and the rear panel 1 is also larger than 1 / 3 of the housing component 10 in the front-rear direction. This results in a smaller front-rear dimension of the air conditioner 100, which helps to reduce the floor space occupied by the air conditioner 100.

[0073] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the heat exchange component 5 is partially shielded on the front side of the fan component 4, as... Figure 8 As shown, the heat exchange component 5 is assembled with the housing component 10 through the first connecting part 53, and the first connecting part 53 is exposed outside the shielding range of the fan component 4.

[0074] The heat exchange component 5 partially obstructs the front side of the fan component 4, and after the fan component 4 is assembled with the housing component 10, it will not obstruct the assembly of the first connecting part 53 with the housing component 10. Therefore, the heat exchange component 5 is not assembled and connected to the fan component 4 and the rear panel 1 at least earlier.

[0075] Optionally, the fan component 4 is first assembled and connected to the rear panel 1. After the fan component 4 is assembled with the housing component 10, the part on the housing component 10 used for the connection of the first connection part 53 is exposed without obstruction. Then the heat exchange component 5 is assembled and connected to the rear panel 1.

[0076] Alternatively, the heat exchange component 5 and the fan component 4 can be assembled and connected as a whole, and then assembled together onto the rear panel 1. When the fan component 4 is assembled with the rear panel 1, the assembly of the first connecting part 53 is not obstructed. Both the fan component 4 and the heat exchange component 5 can be installed onto the rear panel 1.

[0077] In some embodiments of this utility model, such as Figure 2 As shown, the heat exchange component 5 includes a heat exchanger bracket 52 and a heat exchanger 51. The heat exchanger 51 is mounted on the heat exchanger bracket 52, as... Figure 8 , Figure 10 and Figure 12 As shown, the first connecting part 53 includes first connecting ears 521 located at the upper and lower ends of the heat exchanger bracket 52. The first connecting ears 521 are connected to the rear panel 1 by fasteners.

[0078] The heat exchanger bracket 52 is fixedly connected to the rear panel 1 at least through the first connecting ears 521 at both the upper and lower ends. The heat exchanger bracket 52 is subjected to uniform stress, which can improve the assembly stability of the heat exchanger bracket 52. Furthermore, the fasteners pass through the first connecting ears 521 and are fixedly connected to the rear panel 1, which can improve the connection reliability of the heat exchanger bracket 52.

[0079] The first connecting ears 521 located at both the upper and lower ends of the heat exchanger 51 are exposed outside the shielding range of the fan component 4. After the fan component 4 is assembled with the rear panel 1, it does not obstruct the connection between the first connecting ears 521 and the rear panel 1, which facilitates the assembly and connection between the heat exchanger bracket 52 and the rear panel 1.

[0080] In some embodiments of this utility model, such as Figure 7 As shown, the fan component 4 is assembled with the housing component 10 through the second connecting part 43, and the second connecting part 43 is exposed outside the shielding range of the heat exchange component 5.

[0081] The first connecting parts 53 are all exposed outside the shielding range of the fan component 4, and the second connecting parts 43 are all exposed outside the shielding range of the heat exchange component 5. The connection between the fan component 4 and the rear panel 1 will not obstruct the assembly of the heat exchange component 5. Similarly, the connection between the heat exchange component 5 and the rear panel 1 will not obstruct the assembly of the fan component 4 and the rear panel 1.

[0082] The ventilation and heat exchange component 30 can be assembled and connected to the fan component 4 and the rear panel 1 first, and then the heat exchange component 5 can be assembled and connected to the rear panel 1; or the ventilation and heat exchange component 30 can be assembled and connected to the fan component 4 first, and then the two can be assembled together onto the rear panel 1.

[0083] In other embodiments of this utility model, such as Figure 7 As shown, the fan component 4 is assembled with the housing component 10 via a second connecting part 43. There are multiple second connecting parts 43, and as shown... Figure 11 and Figure 12 As shown, at least one second connection portion 43 is located within the shielding area of ​​the heat exchange component 5.

[0084] The ventilation and heat exchange component 30 can only be assembled by first assembling and connecting the fan component 4 to the rear panel 1, and then assembling and connecting the heat exchange component 5 to the rear panel 1.

[0085] With the above design method, it is not necessary to consider whether the arrangement position of the second connection part 43 is within the shielding range of the heat exchange component 5, and the setting position of the second connection part 43 can be flexibly selected.

[0086] In some embodiments of this utility model, such as Figure 7 As shown, the fan component 4 is assembled with the housing component 10 via the second connecting part 43, as... Figure 2 As shown, the fan component 4 includes a volute 42 and a rotor 41. The rotor 41 has a vertically oriented axis and is fitted with the volute 42, as shown in the figure. Figure 9 and Figure 11 As shown, the second connecting portion 43 includes second connecting ears 421 disposed at the upper and lower ends of the through-flow volute 42, as... Figure 13 As shown, the second connecting part 43 also includes a connecting block 431 located on the side of the cross-flow volute 42 away from the heat exchange component 5 in the left-right direction. Both the second connecting ear 421 and the connecting block 431 are connected to the rear panel 1 by fasteners.

[0087] The volute 42 is fixedly connected to the rear panel 1 through the second connecting ears 421 at both the upper and lower ends. The volute 42 is subjected to uniform force, which can improve the assembly stability of the volute 42. In addition, the fasteners pass through the second connecting ears 421 and are fixedly connected to the rear panel 1, which can improve the connection reliability of the volute 42.

[0088] The volute 42 also includes a connecting block 431, which fixes one end of the volute 42 in the left-right direction to the rear panel 1. Fasteners pass through the connecting block 431 and are fixedly connected to the rear panel 1, which can further improve the assembly stability of the volute 42.

[0089] In some embodiments of this utility model, such as Figure 8As shown, there are multiple connecting blocks 431, which are spaced apart in the vertical direction. The force on the flow volute 42 is uniform, which can further improve the assembly reliability of the flow volute 42 and the rear panel 1.

[0090] In some specific embodiments of this utility model, such as Figure 7 and Figure 8 As shown, Figure 7 This is a schematic diagram of the assembly of the through-flow volute 42 and the rear bulkhead 1. Figure 8 This is a schematic diagram of the assembly of the heat exchanger support 52, the cross-flow volute 42, and the rear enclosure 1. The cross-flow volute 42 is fixedly connected to the rear enclosure 1 via second connecting ears 421 at both the upper and lower ends; the heat exchanger support 52 is fixedly connected to the rear enclosure 1 via at least the first connecting ears 521 at both the upper and lower ends, as shown below. Figure 9 As shown, the rear panel 1 is provided with an upper connecting part 12 for connecting to the first connecting lug 521 at the upper end of the heat exchanger bracket 52, such as... Figure 11 As shown, the rear panel 1 is also provided with a lower connecting part 13 for connecting to the first connecting lug 521 at the lower end of the heat exchanger bracket 52.

[0091] Among them, such as Figures 9-12 As shown, after the cross-flow volute 42 is assembled with the rear panel 1, the cross-flow volute 42 does not obstruct the upper connection part 12 and the lower connection part 13 of the heat exchange component. The first connecting ear 521 and the second connecting ear 421 at the upper and lower ends of the heat exchanger bracket 52 are both exposed outside the obstruction range of the fan component 4.

[0092] like Figure 9 and Figure 10 As shown, after the heat exchanger bracket 52 is assembled with the rear panel 1, the heat exchanger bracket 52 does not obstruct the second connecting lug 421 at the upper end of the cross-flow volute 42, and the second connecting lug 421 at the upper end of the cross-flow volute 42 is exposed outside the obstruction range of the heat exchange component 5; while as Figure 11 and Figure 12 As shown, after the heat exchanger bracket 52 is assembled with the rear panel 1, the heat exchanger bracket 52 blocks the second connecting ear 421 at the lower end of the cross-flow volute 42, and the second connecting ear 421 at the lower end of the cross-flow volute 42 is located within the blocking range of the heat exchange component 5.

[0093] Therefore, in some embodiments of this utility model, the ventilation and heat exchange component 30 can only be assembled by first assembling and connecting the fan component 4 with the rear panel 1, and then assembling and connecting the heat exchange component 5 with the rear panel 1.

[0094] In some embodiments of this utility model, such as Figure 8As shown, the front end of the heat exchange component 5 has a first overlapping portion 54, and the front end of the fan component 4 has a second overlapping portion 44. The first overlapping portion 54 overlaps the front side of the second overlapping portion 44 and is fixedly connected by fasteners to form an overlapping connection portion 31.

[0095] The fan component 4 and the heat exchange component 5 are also connected by a first overlapping part 54 and a second overlapping part 44, which can improve the connection stability of the fan component 4 and the heat exchange component 5, and further improve the overall connection stability and reliability of the fan component 4, the heat exchange component 5 and the rear panel 1. The first overlapping part 54 overlaps the front side of the second overlapping part 44, making the assembly of the heat exchange component 5 and the fan component 4 simple and convenient.

[0096] Furthermore, the first overlapping portion 54 of the heat exchange component 5 overlaps the front side of the second overlapping portion 44, and the heat exchange component 5 is assembled and connected to the rear panel 1 at least no earlier than the fan component 4. Optionally, the fan component 4 is first assembled and connected to the rear panel 1, and after the fan component 4 is assembled to the shell component 10, the heat exchange component 5 is then assembled and connected to the rear panel 1 and the fan component 4.

[0097] In some embodiments of this utility model, such as Figure 2 As shown, the heat exchange component 5 includes a heat exchanger bracket 52 and a heat exchanger 51. The heat exchanger 51 is mounted on the heat exchanger bracket 52. The fan component 4 includes a cross-flow volute 42 and a cross-flow impeller 41. The axis of the cross-flow impeller 41 is vertical and cooperates with the cross-flow volute 42.

[0098] like Figure 8 As shown, the lap joint 31 includes: a first lap joint 311 and a second lap joint 312, as... Figure 10 and Figure 12 As shown, the first overlapping connection portion 311 is located at the upper and lower ends of the heat exchanger support 52, as... Figure 8 and Figure 14 As shown, the second overlapping connection part 312 is located at the front end of the heat exchanger bracket 52 near the side of the fan component 4 and is arranged in multiple ways at intervals along the vertical direction.

[0099] The first overlapping portion 54 overlaps the front side of the second overlapping portion 44 and is fixedly connected by fasteners to form an overlapping connection portion 31, which can improve the connection stability of the fan component 4 and the heat exchange component 5. The overlapping connection portion 31 includes first overlapping connection portions 311 respectively located at the upper and lower ends of the heat exchanger bracket 52, which can improve the uniformity of stress on the heat exchanger bracket 52 and improve the assembly stability of the heat exchanger bracket 52.

[0100] In some embodiments of this utility model, such as Figure 8 and Figure 14As shown, the overlapping connection 31 also includes a plurality of second overlapping connection parts 312 spaced apart in the vertical direction, which can further improve the assembly reliability of the heat exchanger support 52 and the cross-flow volute 42.

[0101] By providing first overlapping connection parts 311 at both ends and multiple second overlapping parts 312 located at the front end of the heat exchanger bracket 52 near the side of the fan component 4, the assembly reliability of the heat exchanger bracket 52 and the cross-flow volute 42 is strong.

[0102] In some embodiments of this utility model, such as Figure 2 As shown, the side wall near the heat exchange component 5 at both ends of the housing component 10 is the first side wall 10a, and the side wall near the fan component 4 is the second side wall 10b. The air inlet 101 includes a rear air inlet 1011 formed on the rear panel 1 and / or a side air inlet 1012 formed on the first side wall 10a. The intersection of the second side wall 10b and the front wall 10c of the housing component 10 is the air outlet corner 10d, and the air outlet 102 is formed at the air outlet corner 10d.

[0103] Optionally, such as Figure 2 As shown, the heat exchange component 5 is located near the left side, the fan component 4 is located near the right side, the left side wall of the housing component 10 is the first side wall 10a, and the right side wall of the housing component 10 is the second side wall 10b.

[0104] The rear panel 1 has a rear air inlet 1011, and / or the first side wall 10a has a side air inlet 1012. The air conditioner 100 has a large area for the arrangement of air inlets 101, which is beneficial to increasing the air intake volume of the air conditioner 100. By setting the air outlet 102 at the air outlet corner 10d where the second side wall 10b meets the front wall surface 10c of the housing component 10, the distance between the air outlet 102 and the air inlet 101 can be increased, reducing the backflow phenomenon of the air conditioner 100.
