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

[0045] 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.

[0046] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0047] According to the embodiment of the present utility model, the air conditioner 100, such as Figure 1 and Figure 2 As shown, the air conditioner 100 includes an air conditioner body 10 and an air guide assembly 20. The air conditioner body 10 has an air outlet 1111. The air guide assembly 20 is located at the air outlet 1111 and includes an air guide grille 3 and air guide vanes 4. The air guide grille 3 is rotatably mounted on the air conditioner body 10. The air guide vanes 4 are located upstream of the air guide grille 3 and are arranged in multiples at intervals along the rotation axis R of the air guide grille 3. The air guide vanes 4 are swingably mounted on the air guide grille 3 so as to rotate synchronously with the air guide grille 3 around the rotation axis R.

[0048] The air conditioner body 10 has an air outlet 1111. Heat exchange airflow is sent out from the air outlet 1111 to participate in regulating indoor temperature and air conditions. An air guide assembly 20 is disposed at the air outlet 1111. The air guide assembly 20 acts as a guide, directing the heat exchange airflow outwards, improving the airflow effect of the air conditioner 100, and increasing the airflow range of the air conditioner 100, thereby improving the heat exchange efficiency of the heat exchange airflow sent out by the air conditioner 100. For example, the air guide assembly 20 can be used to increase the airflow range in the horizontal direction, thereby increasing the coverage area of ​​the heat exchange airflow and improving heat exchange efficiency; or, for example, the air guide assembly 20 can also be used to increase the airflow range in the vertical direction, thereby sending the heat exchange airflow a greater distance and improving heat exchange efficiency.

[0049] The air guide assembly 20 includes an air guide grille 3 and air guide vanes 4. The air guide grille 3 provides protection and is located at the air outlet 1111. The grille bars of the air guide grille 3 prevent users from putting their hands into the air outlet 1111 and directly contacting the internal components of the air conditioner body 10, thus improving safety. Both the air guide grille 3 and the air guide vanes 4 have air guiding functions. The air guide grille 3 can guide air using its own grille bars, and it is rotatably mounted on the air conditioner body 10, thereby changing the air guiding angle of the air guide grille 3 and increasing the air delivery range of the air conditioner 100. Optionally, the orientation of the air guide grille 3 can be manually controlled to rotate relative to the air conditioner body 10; alternatively, the air guide grille 3 can be driven to rotate relative to the air conditioner body 10 by a power component, all of which are within the protection scope of this utility model.

[0050] The air guide vane 4 is located upstream of the air guide grille 3. The heat exchange airflow first flows through the air guide vane 4 and then through the air guide grille 3. The air guide vane 4 can swing relative to the air conditioner body 10, thereby changing the air guide angle of the air guide vane 4 and increasing the air supply range of the air conditioner 100. The cooperation between the air guide vane 4 and the air guide grille 3 can further improve the air supply range and air supply effect of the air conditioner 100. There are multiple air guide vanes 4, which are spaced apart along the rotation axis R of the air guide grille 3. It can be understood that the rotation axis R of the air guide grille 3 is perpendicular to the airflow direction of the air outlet 1111, thereby guiding the airflow. By setting multiple air guide vanes 4 at intervals along the rotation axis R of the air guide grille 3, the coverage of the air guide vane 4 can be increased, and the air guiding effect can be improved.

[0051] In related technologies, the air guide grille and air guide vanes are installed on the air conditioner body. When the air guide grille rotates, it will cause motion interference with the air guide vanes, affecting the air guiding effect and the service life of the air guiding components, indicating room for improvement.

[0052] In this embodiment of the utility model, the air conditioner 100 has the air guide vane 4 mounted on the air guide grille 3. The air guide vane 4 rotates synchronously with the air guide grille 3 around the rotation axis R, which can reduce the interference between the air guide grille 3 and the air guide vane 4. When the air guide grille 3 rotates to guide the air, it will not interfere with the air guide vane 4, which improves the working reliability of the air guide assembly 20, improves the guiding effect of the airflow, and the reduction of interference also helps to extend the service life and reduce the working noise.

[0053] In addition, by installing the air guide vane 4 on the air guide grille 3, the air guide assembly 20 can be installed as a whole and then installed onto the air conditioner body 10. Compared with installing the air guide grille and the air guide vane separately on the air conditioner body 10, the assembly steps can be simplified and the assembly efficiency can be improved.

[0054] According to the embodiment of the present utility model, the air conditioner 100 has an air guide vane 4 installed on the air guide grille 3. The air guide vane 4 rotates synchronously with the air guide grille 3 around the rotation axis R. When the air guide grille 3 rotates to guide the air, it will not interfere with the air guide vane 4, thereby improving the working reliability of the air guide assembly 20, improving the guiding effect of the airflow, and reducing the interference between the air guide grille 3 and the air guide vane 4 is also conducive to extending the service life and reducing the working noise of the air guide assembly 20.

[0055] In some embodiments of this utility model, such as Figures 3-5As shown, the rotation axis R extends along the length direction of the air outlet 1111. The air guide grille 3 includes: longitudinal grille bars 31. The length direction of the longitudinal grille bars 31 extends along the length direction of the air outlet 1111. There are multiple longitudinal grille bars 31, which are spaced apart along the width direction of the air outlet 1111. The width direction F1 of the longitudinal grille bars 31 extends along the direction from the upstream side of the air guide grille 3 to the downstream side of the air guide grille 3. The width of the longitudinal grille bars 31 is greater than the wall thickness of the longitudinal grille bars 31, and the width of the longitudinal grille bars 31 constitutes the air guide dimension of the longitudinal grille bars 31.

[0056] The rotation axis R extends along the length of the air outlet 1111. The air guide grille 3 has longitudinal gratings 31 extending along the length of the air outlet 1111, which can increase the coverage of the air guide grille 3 and improve the airflow guiding effect. In addition, there are multiple air guide vanes 4, which are spaced apart along the length of the air outlet 1111, which can increase the coverage of the air guide vanes 4 and improve the airflow guiding effect.

[0057] Optionally, multiple air guide vanes 4 can swing along the extension direction of the rotation axis R of the air guide grille 3, with the air guide vanes 4 and the air guide grille 3 having perpendicular air guide directions, thereby increasing the air guide angle and improving the air guide effect; or, alternatively, multiple air guide vanes 4 can swing in the rotation direction of the air guide grille 3, with the air guide vanes 4 and the air guide grille 3 having the same air guide direction, thereby improving the air guide effect in the same direction.

[0058] In some embodiments, such as Figure 1 As shown, the air conditioner 100 is a vertical air conditioner 100. The length of the air outlet 1111 extends vertically, and the longitudinal bars 31 of the air guide grille 3 extend vertically. Multiple air guide vanes 4 are spaced apart vertically, which can increase the coverage of the heat exchange airflow along the length of the air outlet 1111 and improve the airflow guiding effect. The longitudinal bars 31 can swing left and right, increasing the air supply range of the air conditioner 100 in the horizontal direction.

[0059] Alternatively, in some other embodiments, the air conditioner 100 is a wall-mounted air conditioner with an air outlet 1111 extending horizontally, longitudinal bars 31 of the air guide grille 3 extending horizontally, and multiple air guide vanes 4 spaced apart horizontally. This increases the coverage of the heat exchange airflow along the length of the air outlet 1111, improving the airflow guiding effect. The longitudinal bars 31 can guide air vertically, increasing the air supply range of the air conditioner 100 in the vertical direction.

[0060] The longitudinal grille 31 extends along the length of the air outlet 1111. There are multiple longitudinal grilles 31, which are spaced apart along the width of the air outlet 1111. The air guide grille 3 has a wide coverage of the air outlet 1111, which can play a protective role and help improve the air guiding effect.

[0061] The width direction F1 of the longitudinal grid strip 31 extends from the upstream side of the air guide grille 3 to the downstream side of the air guide grille 3, and the thickness direction F2 of the longitudinal grid strip 31 is perpendicular to the direction from the upstream side of the air guide grille 3 to the downstream side of the air guide grille 3. Therefore, as Figure 5 As shown, the dashed line with arrows indicates the direction of airflow, and the width direction F1 of the longitudinal grid 31 is the direction of airflow guidance. The width of the longitudinal grid 31 constitutes the guiding dimension of the longitudinal grid 31.

[0062] By setting the width of the longitudinal grid bar 31 to be greater than the thickness of the longitudinal grid bar 31, the width of the longitudinal grid bar 31 is larger, and a guide channel for airflow can be formed in the width direction F1 of the longitudinal grid bar 31, thereby realizing the guiding function by using the longitudinal grid bar 31.

[0063] In some embodiments of this utility model, such as Figure 4 As shown, the air guide grille 3 also includes: horizontal grille 32, the length direction of which extends along the width direction of the air outlet 1111, and multiple horizontal grille 32 and multiple vertical grille 31 are connected to protect the air outlet 1111.

[0064] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the longitudinal grille 31 includes a first grille 311 and a second grille 312. The first grille 311 is provided on both sides of the width of the air guide grille 3, and multiple second grilles 312 are located between two first grilles 311. The guiding dimension B of the first grille 311 is larger than the guiding dimension A of the second grille 312, and as shown... Figure 5 and Figure 6 As shown, the upstream end of the first grid bar 311 protrudes towards the upstream side of the guide grille 3 relative to the upstream end of the second grid bar 312.

[0065] It is worth noting that the width direction of the air guide grille 3 refers to the overall width direction of the air guide grille 3, which is consistent with the width direction of the air outlet 1111, and does not refer to the width direction F1 of the longitudinal grille bars 31. The air guide grille 3 includes a plurality of longitudinal grille bars 31 spaced apart along the width direction of the air outlet 1111. The longitudinal grille bars 31 located at both ends are the first grille bars 311, and the longitudinal grille bars 31 located between two first grille bars 311 are the second grille bars 312.

[0066] The width of the first grid bar 311 is the guiding dimension B of the first grid bar 311, and the width of the second grid bar 312 is the guiding dimension A of the second grid bar 312. The guiding dimension B of the first grid bar 311 is greater than the guiding dimension A of the second grid bar 312. Thus, an air guiding channel extending along the width direction F1 of the longitudinal grid bar 31 is formed between the two first grid bars 311, which can guide the airflow and enhance the guiding effect on the airflow.

[0067] And, as Figure 5 and Figure 6 As shown, the dashed line with arrows indicates the direction of airflow. The airflow flows from the upstream side of the air guide grille 3 to the downstream side of the air guide grille 3. The upstream end of the first grille bar 311 protrudes towards the upstream side of the air guide grille 3 relative to the upstream end of the second grille bar 312. The first grille bar 311 protrudes into the air outlet 1111, which helps to reduce the occupation of the external space of the air conditioner 100. While increasing the guiding effect on the airflow, it can also improve the working reliability of the air guide grille 3 and reduce interference with the outside of the air conditioner 100.

[0068] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the downstream ends of each first grid bar 311 and the downstream ends of each second grid bar 312 are located on the same arc-shaped surface protruding towards the downstream side of the guide grille 3.

[0069] The downstream section of each first grille 311 and the downstream end of each second grille 312 are located on the same arc-shaped surface. The outer surface of the air guide grille 3 facing outward is flush with the outer surface, and the first grille 311 protrudes into the air outlet 1111. While increasing the volume of the air guide channel between the two first grilles 311 and improving the air guiding effect, it can also reduce the occupation of the external space of the air conditioner 100 and reduce interference with the outside of the air conditioner 100.

[0070] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the surface of the first grid bar 311 away from the second grid bar 312 is a convex curved surface.

[0071] The air guide grille 3 is rotatably disposed at the air outlet 1111. The first grille 311 is located on both sides of the width of the air guide grille 3 and serves as the width edge of the air guide grille 3. By setting the surface of the first grille 311 away from the second grille 312 as an outwardly convex curved surface, it is beneficial for the first grille 311 to rotate relative to the air outlet 1111, which can reduce the motion interference between the air guide grille 3 and the structure at the air outlet 1111 and improve the motion stability of the air guide grille 3.

[0072] In some embodiments of this utility model, such as Figure 5 As shown, the airflow guiding dimension B of the first grid bar 311 is greater than or equal to twice the airflow guiding dimension A of the second grid bar 312. The airflow channel formed by the first grid bar 311 has a larger volume, which can improve the airflow guiding effect.

[0073] In some embodiments of this utility model, such as Figure 3 As shown, the swing axis S of the air guide vane 4 extends along the width direction of the air outlet 1111, so that the air guide vane 4 can swing along the length direction of the air outlet 1111.

[0074] In some embodiments, such as Figure 1 As shown, the air conditioner 100 is a vertical air conditioner 100. The length of the air outlet 1111 extends vertically, and multiple air guide vanes 4 are spaced apart vertically. The swing axis S of the air guide vanes 4 extends along the width of the air outlet 1111, realizing the up-and-down swing of the air guide vanes 4. It is worth noting that the swing axis S of the air guide vanes 4 can extend horizontally or at a certain angle to the horizontal direction, which can be selected according to actual needs.

[0075] In some embodiments of this utility model, such as Figure 3 As shown, the length direction of the air guide grille 3 and the rotation axis R both extend along the length direction of the air outlet 1111, as... Figure 4 and Figure 8 As shown, mounting portions 33 are provided on both sides of the width of the air guide grille 3, and the two ends of each air guide blade 4 are rotatably connected to the mounting portion 33 on the corresponding side through the connecting portion 41, so that they can swing around the swing axis S.

[0076] The rotation axis R extends along the length of the air outlet 1111, and the length of the air guide grille 3 extends along the length of the air outlet 1111, which can increase the coverage of the air guide grille 3 and improve the air guiding effect.

[0077] By providing mounting parts 33 on both sides of the width of the air guide grille 3, the two ends of the air guide blade 4 are rotatably connected to the two sides of the width of the air guide grille 3. The air guide blade 4 is installed at both ends, which has strong installation reliability and can improve the swing stability of the air guide blade 4 around the swing axis S.

[0078] In some embodiments of this utility model, such as Figure 8 As shown, one of the connecting part 41 and the mounting part 33 includes a rotating shaft 331, and the other of the connecting part 41 and the mounting part 33 includes a retaining ring 411. The retaining ring 411 is an open annular shape and defines a retaining groove 412. The rotating shaft 331 is engaged into the retaining groove 412 from the opening position of the retaining ring 411.

[0079] The air guide vane 4 and the air guide grille 3 are connected by a snap ring 411 and a rotating shaft 331, allowing the air guide vane 4 to rotate relative to the air guide grille 3. The snap ring 411 and the rotating shaft 331 are simple to connect and improve assembly efficiency.

[0080] In some embodiments of this utility model, such as Figure 8 As shown, the mounting part 33 includes a rotating shaft 331, and the connecting part 41 includes a retaining ring 411. The interference when the air guide vane 4 is installed to the air guide grille 3 is small, which facilitates the assembly of the air guide vane 4.

[0081] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the air guide grille 3 bends towards its downstream side to form an avoidance cavity 34 on its upstream side, and at least a portion of the air guide vane 4 is located in the avoidance cavity 34. The air guide grille 3 bends towards its downstream side so that it is constructed with a shape that protrudes from the center towards the downstream side, thus forming the avoidance cavity 34 on its upstream side. The avoidance cavity 34 not only serves as a guide channel for airflow, but also accommodates the air guide vane 4, making the structure of the air guide vane 4 and the air guide grille 3 compact, reducing the space occupied by the air guide vane 4, and reducing the interference between the air guide vane 4 and the air guide grille 3.

[0082] like Figure 8 and Figure 11 As shown, the two sides of the width of the air guide grille 3 are side portions 35, the rotating shaft 331 is a cantilever shaft and extends from the side portion 35 toward the avoidance cavity 34, and the retaining ring 411 is sleeved on the rotating shaft 331 and stopped by the side portion 35 to restrict the retaining ring 411 from coming out in the direction away from the avoidance cavity 34.

[0083] The rotating shaft 331 extends from the wide edge of the air guide grille 3 inward toward the inward clearance cavity 34. Compared to a design where the rotating shaft extends away from the clearance cavity, this reduces the space occupied and minimizes interference when the air guide grille 3 rotates. Furthermore, by extending the rotating shaft 331 inward from the wide edge of the air guide grille 3, the side portion 35 of the wide edge of the air guide grille 3 can also limit the retaining ring 411 fitted on the rotating shaft 331, preventing the retaining ring 411 from dislodging away from the clearance cavity 34 and improving the reliability of the fit between the air guide grille 3 and the air guide vane 4.

[0084] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the wind guide vane 4 includes a vane body 42, and each end of the vane body 42 has a retaining ring 411. The opening of the retaining ring 411 is open towards the downstream side of the wind guide grille 3, and a clearance gap 43 is formed between the vane body 42 and the retaining ring 411. The free end of the cantilever of the rotating shaft 331 has a limiting protrusion 3311 located in the clearance gap 43 and abuts against the side of the retaining ring 411 away from the side portion 35.

[0085] The air guide vane 4 is installed along the upstream side of the air guide grille 3 towards the downstream side of the air guide grille 3, so that the rotating shaft 331 is inserted into the slot 412 from the opening position of the retaining ring 411.

[0086] A limiting protrusion ring 3311 is provided at the free end of the cantilever of the rotating shaft 331. The limiting protrusion ring 3311 extends radially along the rotating shaft 331 and abuts against the side of the retaining ring 411 away from the side portion 35. The limiting protrusion ring 3311 can prevent the retaining ring 411 from disengaging in the direction away from the side portion 35. By providing the limiting protrusion ring 3311, the reliability of the fit between the air guide grille 3 and the air guide vane 4 can be further improved. The vane body 42 and the retaining ring 411 are spaced apart, forming a clearance gap 43 that can accommodate the limiting protrusion ring 3311.

[0087] In some embodiments of this utility model, such as Figure 3 and Figure 11 As shown, the air guide grille 3 includes: longitudinal grille bars 31, the length direction of which extends along the length direction of the air outlet 1111, there are multiple longitudinal grille bars 31 and they are spaced apart along the width direction of the air outlet 1111, the width direction F1 of the longitudinal grille bars 31 extends along the direction from the upstream side of the air guide grille 3 to the downstream side of the air guide grille 3, the width of the longitudinal grille bars 31 is greater than the wall thickness of the longitudinal grille bars 31, and longitudinal grille bars 31 are respectively provided on both sides of the width of the air guide grille 3 so that the longitudinal grille bars 31 form the side part 35.

[0088] The longitudinal grille bars 31 extend along the length of the air outlet 1111. Multiple longitudinal grille bars 31 are spaced apart along the width of the air outlet 1111. The width direction F1 of the longitudinal grille bars 31 extends from the upstream side of the air guide grille 3 to the downstream side of the air guide grille 3. The thickness direction F2 of the longitudinal grille bars 31 is perpendicular to the direction from the upstream side of the air guide grille 3 to the downstream side of the air guide grille 3. By setting the width of the longitudinal grille bars 31 to be greater than their thickness, a larger width allows for the formation of airflow guiding channels along the width direction F1 of the longitudinal grille bars 31, thereby achieving a guiding function.

[0089] The longitudinal bars 31 located on both sides of the width of the air guide grille 3 form the side part 35. The pivot 331 is formed on the longitudinal bars 31 located on both sides of the width of the air guide grille 3. The longitudinal bars 31 can not only guide the air, but also be assembled with the air guide vane 4, thereby simplifying the structure of the air guide grille 3, reducing interference with the airflow, and improving the airflow guiding effect.

[0090] In some embodiments of this utility model, such as Figure 3 , Figure 4 and Figure 8 As shown, the air guide assembly 20 also includes a connecting rod 5, which extends along the rotation axis R and is connected to a plurality of air guide vanes 4 and causes the plurality of air guide vanes 4 to swing synchronously. The connecting rod 5 is located between the air guide grille 3 and the air guide vanes 4, and the air guide vanes 4 have a clearance groove 44 formed on them to avoid the connecting rod 5.

[0091] The air guide vanes 4 are spaced apart along the rotation axis R, and the connecting rod 5 extends along the rotation axis R to connect with multiple air guide vanes 4 to drive multiple air guide vanes 4 to swing synchronously, thereby improving the air guiding effect of the air guide vanes 4.

[0092] The connecting rod 5 also rotates synchronously with the air guide grille 3 around the rotation axis R. By setting the connecting rod 5 between the air guide grille 3 and the air guide vane 4, the space occupied by the external environment can be reduced, making the structure between the air guide grille 3, the air guide vane 4 and the connecting rod 5 compact, and reducing the interference between the air guide grille 3 and other structures during the rotation process.

[0093] In some embodiments of this utility model, such as Figure 2 and Figure 7 As shown, the air conditioner body 10 includes: a housing component 11, which includes an outer shell 111 and an air outlet frame 112. The air outlet 1111 is an open type and is formed in the outer shell 111. The air outlet frame 112 is disposed inside the outer shell 111 and is integrally formed with the outer shell 111. The air outlet frame 112 defines an air outlet duct 1121 that communicates with the air outlet 1111. Wherein, as... Figure 12 As shown, the air guide assembly 20 can be installed into the air outlet duct 1121 through the air outlet 1111, and the air guide grille 3 is rotatably connected to the air outlet frame 112.

[0094] The housing component 11 includes a housing 111 and an air outlet frame 112. The housing 111 is the outer contour of the air conditioner 100. The air outlet frame 112 is disposed inside the housing 111 and defines an air outlet duct 1121 for airflow. Airflow flows out of the air conditioner 100 through the air outlet 1111 via the air outlet duct 1121. By integrally molding the air outlet frame 112 with the housing 111, the integrity of the air outlet frame 112 and the housing 111 can be improved, preventing airflow from leaking out from the structural connection between the air outlet frame 112 and the housing 111, which is beneficial to improving the air delivery of the air conditioner 100.

[0095] like Figure 12 As shown, the air outlet frame 112 is integrally formed with the outer shell 111. The internal space of the outer shell 111 is relatively small, while the air outlet 1111 is an open form formed on the outer shell 111. Therefore, the air guide assembly 20 is installed into the air outlet duct 1121 through the air outlet 1111, which provides a large operating space and reduces the assembly difficulty. After the air guide assembly 20 is installed into the air outlet duct 1121, the air guide grille 3 is rotatably connected to the air outlet frame 112, so that the air guide grille 3 can guide the airflow in the air outlet duct 1121.

[0096] In some embodiments of this utility model, such as Figure 7As shown, a drive motor 60 is installed on the air outlet frame 112. The drive motor 60 is connected to the air guide grille 3 to drive the air guide grille 3 to rotate. The drive motor 60 is installed on the air outlet frame 112, and the air guide grille 3 is rotatably connected to the air outlet frame 112. The drive motor 60 is connected to the air guide grille 3 to drive the air guide grille 3 to rotate, which facilitates the use of the air guide grille 3.

[0097] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the contour edge of the air guide vane 4 on the side away from the air guide grille 3 is formed as an arc-shaped edge 45 protruding in the direction away from the air guide grille 3, as... Figure 2 and Figure 8 As shown, the air outlet frame 112 includes an arc-shaped wall 1122 coaxially arranged with the arc edge 45, and the air outlet frame 112 defines the air outlet duct 1121 through the arc-shaped wall 1122.

[0098] The curved edge 45 of the air guide vane 4 faces the inner side of the housing component 11, and the air outlet frame 112 includes a curved wall 1122 coaxially arranged with the curved edge 45. The curved wall 1122 and the curved edge 45 cooperate with each other. When the air guide vane 4 rotates synchronously with the air guide grille 3 around the rotation axis R, the air guide vane 4 will not interfere with the air outlet frame 112, thereby improving the motion stability of the air guide assembly 20.

[0099] And, as Figure 2 As shown, the air outlet frame 112 defines the air outlet duct 1121 by the arc wall 1122. By forming the arc wall 1122, the air outlet duct 1121 is constructed in an flared form facing the air outlet 1111, which is beneficial to improving the air outlet effect of the air conditioner 100.

[0100] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner body 10 includes: a housing component 11, a fan component 12, and a heat exchange component 13. The length direction of the housing component 11 is vertical, and the dimension L of the housing component 11 in the front-to-back direction is smaller than the dimension W of the housing component 11 in the left-to-right direction. The left and right end walls of the housing component 11 are respectively the first end wall 11a and the second end wall 11b. An air outlet 1111 is formed at the intersection of the front end wall 115 of the housing component 11 and the first end wall 11a, and the length direction of the air outlet 1111 is vertical. An air inlet 1112 is formed on at least one of the second end wall 11b, the front end wall 115 of the housing component 11, and the rear end wall 116 of the housing component 11. The fan component 12 is disposed inside the housing component 11 and includes a vertically oriented cross-flow fan wheel 121. The heat exchange component 13 is disposed inside the housing component 11 and is located on the side of the fan component 12 near the second end wall 11b.

[0101] The heat exchange component 13 is used to exchange heat with the flowing air, the fan part 3 is used to provide the flowing air, and the heat exchange air delivered by the air conditioner 100 can regulate the indoor temperature.

[0102] By designing the housing component 11 such that its dimension L in the front-to-back direction is smaller than its dimension W in the left-to-right direction, the size in the front-to-back direction can be reduced, thus reducing the space occupied in the front-to-back direction and facilitating the arrangement of the air conditioner 100.

[0103] The housing has a left end wall 113 located on the left side and a right end wall 114 located on the right side, optionally, as... Figure 2 As shown, the left end wall 113 is constructed as the first end wall 11a, and the right end wall 114 is constructed as the second end wall 11b; alternatively, the left end wall 113 may be constructed as the second end wall 11b, and the right end wall 114 may be constructed as the first end wall 11a, which can be selected according to actual needs.

[0104] An air outlet 1111 is formed at the junction of the front end wall 115 and the first end wall 11a of the housing component 11. An air inlet 1112 is formed on at least one of the second end wall 11b, the front end wall 115 of the housing component 11, and the rear end wall 116 of the housing component 11. The air conditioner 100 has a large area for arranging the air inlet 1112, which facilitates the arrangement of the air conditioner 100.

[0105] The heat exchange component 13 is disposed within the housing component 11 and located on the side of the fan component 12 near the second end wall 11b. By arranging the heat exchange component 13 and the fan component 12 in the left-right direction, the size in the front-back direction can be reduced, thus minimizing the space occupied in the front-back direction. This results in a compact structure for the heat exchange component 13 and the fan component 12, a smaller air conditioner body, and a smaller installation footprint. Furthermore, the heat exchange components occupy less space in the front-back direction of the fan component 12, allowing for more space in the front-back direction of the cross-flow fan wheel 121, which facilitates increasing the size of the cross-flow fan wheel 121 and thereby improving the air delivery effect of the air conditioner 100.
