[0059] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0060] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0061] Please refer to the following Figures 1 to 29 An air conditioner 100 according to an embodiment of the present invention will be described.

[0062] like Figures 1 to 8 As shown, the air conditioner 100 according to the embodiment of the present invention includes: a casing assembly, a fan component and a heat exchanger 2, the casing assembly is formed with an air inlet and an air outlet, and a first limiting groove 11 and a second limiting groove 12 are formed on the casing assembly, the fan component is arranged in the casing assembly, the heat exchanger 2 is arranged in the casing assembly and has a first end 21 and a second end 22, the first end 21 is accommodated in the first limiting groove 11 and abuts against the inner wall of the first limiting groove 11, and a connecting structure 13 is also provided on the casing assembly, and the connecting structure 13 can be used to install the support member 3, and the support member 3 can be selectively installed in the casing assembly. When the support member 3 is not installed in the casing assembly, the second end 22 is accommodated in the second limiting groove 12 and abuts against the inner wall of the second limiting groove 12. When the support member 3 is installed in the casing assembly, the support member 3 is located in the second limiting groove 12 and the second end 22 is sealed and abuts against the support member 3.

[0063] That is, when the support member 3 is not installed in the housing assembly, the two ends of the heat exchanger 2 are respectively limited by the first limiting groove 11 and the second limiting groove 12, that is, the first limiting groove 11 and the second limiting groove 12 jointly limit the heat exchanger 2; when the support member 3 is installed in the housing assembly, the two ends of the heat exchanger 2 are respectively limited by the first limiting groove 11 and the support member 3, and the first limiting groove 11 and the support member 3 jointly limit the heat exchanger 2. In other words, regardless of whether the support member 3 is installed, the first end 21 of the heat exchanger 2 is limited by the first limiting groove 11, and the first limiting groove 11 and the support member 3 can be used to limit and support the second ends 22 of two different specifications of heat exchangers 2.

[0064] Therefore, by providing the connection structure 13 on the housing assembly, it is possible to select whether to install the support member 3 according to the specifications of the heat exchanger 2. The support member 3 can adapt to the differences between heat exchangers 2 of different specifications, allowing heat exchangers 2 of multiple different specifications to share a housing assembly of the same specification, thereby effectively reducing the number of specifications of the housing assembly and reducing the production cost of the air conditioner 100. In addition, because the support member 3 is in sealed contact with the second end 22, the airflow on the upstream side of the second end 22, i.e., the side of the second end 22 near the air inlet, can be prevented from directly flowing to the fan component through the gap between the support member 3 and the second end 22. This ensures that the airflow on the upstream side of the heat exchanger 2 passes through the heat exchanger 2 before flowing to the fan component, thereby preventing the airflow entering the air conditioner 100 from being directly discharged without heat exchange, thereby improving the heating or cooling efficiency of the air conditioner 100.

[0065] According to the air conditioner 100 of the embodiment of the present invention, by providing a connecting structure 13 on the casing assembly, it is possible to select whether to install the support member 3 according to the specifications of the heat exchanger 2, so that the support member 3 can adapt to the differences between the heat exchangers 2 of different specifications, so that a plurality of heat exchangers 2 of different specifications can share a casing assembly of the same specification, thereby effectively reducing the number of specifications of the casing assembly and reducing the production cost of the air conditioner 100. In addition, by sealing the support member 3 with the second end 22, the heating or cooling efficiency of the air conditioner 100 can be improved.

[0066] According to some embodiments of the present invention, the support member 3 includes a main body 31 and a sealing rib 32. The sealing rib 32 is disposed on the side of the main body 31 facing the second end 22 and extends axially along the fan component. When the support member 3 is installed in the housing assembly, the sealing rib 32 abuts the second end 22. In other words, the sealing rib 32 is supported between the main body 31 and the second end 22, thereby effectively sealing the gap between the main body 31 and the second end 22. Therefore, the abutment between the sealing rib 32 and the second end 22 improves the sealing effect between the support member 3 and the heat exchanger 2, thereby preventing airflow on the upstream side of the heat exchanger 2 from directly flowing through the gap between the main body 31 and the second end 22 to the fan component. In other words, this ensures that airflow on the upstream side of the heat exchanger 2 passes through the heat exchanger 2 before flowing to the fan component, thereby improving the temperature regulation effect of the heat exchanger 2 on the airflow, thereby enhancing the heating or cooling efficiency of the air conditioner 100.

[0067] According to some embodiments of the present invention, Figures 14 to 17As shown, multiple sealing ribs 32 are provided, spaced apart along the thickness direction of the second end 22. That is, multiple sealing ribs 32 are arranged sequentially in a direction from the upstream side of the second end 22, i.e., the side of the second end 22 near the air inlet, toward the downstream side of the second end 22, i.e., the side of the second end 22 near the fan component. The support member 3 can form a multi-sealing structure through the abutment of the multiple sealing ribs 32 with the second end 22, thereby enhancing the sealing effect between the support member 3 and the second end 22 and further preventing airflow on the upstream side of the heat exchanger 2 from directly flowing through the gap between the main body 31 and the second end 22 to the fan component. Furthermore, by providing multiple sealing ribs 32 to jointly support the second end 22, the stability of the support member 3's limited support for the heat exchanger 2 can be enhanced. Furthermore, the multiple sealing ribs 32 can effectively distribute the pressure exerted by the heat exchanger 2 on the support member 3, preventing damage to a single sealing rib 32 due to excessive pressure, thereby ensuring the structural strength of the support member 3.

[0068] According to some embodiments of the present invention, a sealing rib 32 is located below the second end 22, and a first guide groove 33 extending along the axial direction of the fan component is formed between any two adjacent sealing ribs 32. During operation of the heat exchanger 2, when the refrigerant temperature within the heat exchanger 2 is low and the temperature of the introduced airflow is high, water droplets are likely to condense on the refrigerant pipes of the heat exchanger 2. Therefore, by providing the first guide groove 33, condensed water on the heat exchanger 2 flows toward the second end 22 under its own weight and can drip into the first guide groove 33. In other words, the first guide groove 33 can catch condensed water dripping from the second end 22 of the heat exchanger 2.

[0069] In some embodiments, the heat exchanger 2 includes a first heat exchange portion 23 and a second heat exchange portion 24 arranged along the circumference of the fan component, the first heat exchange portion 23 is located in front of the second heat exchange portion 24, the upper ends of the first heat exchange portion 23 and the second heat exchange portion 24 are connected, the first heat exchange portion 23 extends downwardly at an angle from the back to the front, and the lower end of the first heat exchange portion 23 constitutes the first end 21, the second heat exchange portion 24 extends downwardly at an angle from the front to the back, and the lower end of the second heat exchange portion 24 constitutes the second end 22. Therefore, the condensation water generated on the first heat exchange portion 23 can flow downward along the first heat exchanger 2 under the action of gravity and drip into the first limiting groove 11 through the first end 21. When the support member 3 is not installed in the housing assembly, the condensation water generated on the second heat exchange portion 24 can flow downward along the second heat exchanger 2 under the action of gravity and drip into the second limiting groove 12 through the second end 22. When the support member 3 is installed in the housing assembly, the condensation water generated on the second heat exchange portion 24 can flow downward along the second heat exchanger 2 under the action of gravity and drip into the first guide groove 33 through the second end 22. Among them, the first limiting groove 11, the second limiting groove 12 and the first guide groove 33 are all connected to the water receiving tray of the air conditioner 100 to ensure that the condensation water in the first limiting groove 11, the second limiting groove 12 and the first guide groove 33 can be discharged into the water receiving tray and then discharged from the air conditioner 100.

[0070] According to some embodiments of the present invention, the support member 3 is formed with a drain port 321, which is in communication with the first guide groove 33. Thus, condensation water within the first guide groove 33 can be promptly drained through the drain port 321, thereby preventing the condensation water from remaining in the first guide groove 33 and generating bacteria, mud, etc., thereby ensuring the cleanliness of the internal environment of the air conditioner 100. In some embodiments, the drain port 321 is in communication with the water receiving tray of the air conditioner 100, so that the condensation water within the first guide groove 33 can be discharged into the water receiving tray through the drain port 321 and then discharged from the air conditioner 100 through the water receiving tray.

[0071] According to some embodiments of the present invention, Figures 18 to 21As shown, multiple first guide grooves 33 are formed, and a water receiving groove 122 is formed at the bottom of the second limiting groove 12, located below the multiple first guide grooves 33. The height of the multiple first guide grooves 33 decreases as they approach the fan component. A first communication port 322 is formed on the sealing rib 32 between two adjacent first guide grooves 33, connecting the first guide grooves 33 on both sides. At least part of the drainage port 321 is formed on the sealing rib 32 closest to the fan component, connecting the first guide groove 33 with the water receiving groove 122. In other words, the closer the first guide groove 33 is to the fan component, the lower its height. Therefore, as the first guide groove 33 approaches the fan component, condensation water within the first guide groove 33 can flow into the adjacent first guide groove 33 through the first communication port 322 under the action of its own gravity. Condensation water that enters the first guide groove 33 closest to the fan component can be discharged into the water receiving groove 122 through the drainage port 321, thereby preventing condensation water from remaining on the support member 3. The water receiving tank 122 may be connected to the water receiving tray of the air conditioner 100 , so that the condensed water in the water receiving tank 122 may be discharged into the water receiving tray and then discharged from the air conditioner 100 through the water receiving tray.

[0072] In some embodiments, the direction in which the sealing rib 32 extends away from the main body 31 is perpendicular to the thickness direction of the second end 22. The sealing rib 32 and the second end 22 abut against each other along the circumference of the fan component. Multiple first communication openings 322 and drain openings 321 are provided, arranged along the axial direction of the fan component. Both the first communication openings 322 and the drain openings 321 are formed by recessing the side of the sealing rib 32 away from the main body 31, away from the second end 22. The first communication openings 322 and the drain openings 321 extend to the connection point between the sealing rib 32 and the main body 31. Therefore, the difficulty of processing and forming the first communication openings 322 and the drain openings 321 can be reduced, while ensuring that the first communication openings 322 and the drain openings 321 can completely drain condensation water from the first guide groove 33, thereby preventing the condensation water remaining in the first guide groove 33 from breeding bacteria and mud.

[0073] According to some embodiments of the present invention, the drain port 321 and the first connecting port 322 are staggered in the axial direction of the fan component. This prevents the drain port 321 and the first connecting port 322 from being arranged relative to each other along the thickness direction of the second end 22 to form a continuous airflow channel, thereby preventing the airflow on the upstream side of the second end 22 from directly flowing to the fan component through the first connecting port 322 and the drain port 321 in sequence while ensuring the drainage effect of the first guide groove 33, thereby ensuring the sealing effect between the support member 3 and the second end 22. In addition, when there are three or more first guide grooves 33, the first connecting port 322 is formed on the two sealing ribs 32 located in the middle position, and the first connecting ports 322 on the two adjacent sealing ribs 32 are also staggered in the axial direction of the fan component.

[0074] According to some embodiments of the present invention, a fixing structure 34 connected to the connecting structure 13 is formed on the support member 3, and the fixing structure 34 is provided on the sealing rib 32 farthest from the fan component. In other words, the fixing structure 34 is located on the side of the support member 3 away from the fan component, which can effectively increase the distance between the fixing structure 34 and the fan component. The side of the support member 3 away from the fan component can also provide a larger operating space for connecting the fixing structure 34 and the connecting structure 13. At the same time, the connection position of the fixing structure 34 and the connecting structure 13 can be more intuitively seen, thereby reducing the difficulty of connecting the fixing structure 34 and the connecting structure 13, thereby improving the assembly efficiency of the support member 3 and the casing assembly.

[0075] According to some embodiments of the present invention, Figure 1 and Figure 21 As shown, a first positioning surface 323 opposite to the second end 22 is formed on the sealing rib 32 farthest from the fan component, and a first sealing member 4 is provided on the first positioning surface 323. When the support member 3 is installed in the housing assembly, the first sealing member 4 abuts against the second end 22. Therefore, the first sealing member 4 can better fill the gap between the sealing rib 32 farthest from the fan component and the second end 22, and can better increase the sealing position between the support member 3 and the second end 22. In addition, the abutting position of the first sealing member 4 and the second end 22 is closer to the upstream side of the second end 22, so that the first sealing member 4 can effectively block the airflow from flowing to the sealing rib 32, thereby further improving the sealing effect between the support member 3 and the second end 22. Secondly, by providing the first positioning surface 323, the installation position of the first sealing member 4 is easier to identify, thereby reducing the positioning and installation difficulty of the first sealing member 4.

[0076] In some embodiments, the first seal 4 is a sealing sponge, and the first seal 4 is adhesively connected to the first positioning surface 323. The side of the sealing rib 32 farthest from the fan component facing the fan component is the first side 324. The first positioning surface 323 is formed by the end of the first side 324 away from the main body 31, and extends obliquely in the direction from the main body 31 to the second end 22 in the direction away from the fan component, thereby making the first positioning surface 323 more obvious, so that the installer can identify and install the first seal 4.

[0077] According to some embodiments of the present invention, a first sealing member 4 is provided on the support member 3. When the support member 3 is installed in the housing assembly, the first sealing member 4 abuts against the second end 22. Thus, the provision of the first sealing member 4 effectively fills the gap between the support member 3 and the second end 22, preventing airflow on the upstream side of the second end 22 from directly flowing through the gap between the support member 3 and the second end 22 toward the fan component. This ensures that airflow on the upstream side of the heat exchanger 2 passes through the heat exchanger 2 before flowing toward the fan component, thereby improving the heating or cooling efficiency of the air conditioner 100.

[0078] According to some embodiments of the present invention, Figures 11 to 13 As shown, the support member 3 is snap-connected to the connecting structure 13. The snap-connection is simple to use and easy to release. This reduces the difficulty of installing the support member 3 in the housing assembly and improves the efficiency of installing the support member 3 in the housing assembly.

[0079] In some embodiments, the connecting structure 13 includes a plurality of snap-in holes 132 arranged at intervals along the axial direction of the fan component, and a plurality of snap-in holes 342 arranged at intervals along the axial direction of the fan component are formed on the side of the support member 3 facing the snap-in holes 132, and the plurality of snap-in holes 342 are snap-fitted with the plurality of snap-in holes 132 in a one-to-one correspondence.

[0080] According to some embodiments of the present invention, a fixing structure 34 connected to the connecting structure 13 is formed on the support member 3, and the connecting structure 13 includes a plurality of assembly grooves 131 arranged at intervals along the axial direction of the fan component, and the assembly grooves 131 are open toward the support member 3, and a snap-fit ​​hole 132 is formed on the inner bottom wall of the assembly groove 131, and a positioning protrusion 133 is provided on the inner bottom wall of at least one assembly groove 131. The fixing structure 34 includes a positioning block 341 and a plurality of snaps 342 arranged at intervals along the axial direction of the fan component. The positioning block 341 is suitable for being inserted into the assembly groove 131, and a positioning matching groove 343 is formed on the side of the positioning block 341 facing the positioning protrusion 133. The positioning protrusion 133 is suitable for being inserted into the positioning matching groove 343. The positioning matching groove 343 is used to limit the axial movement of the positioning protrusion 133 in the fan component, and the snaps 342 are snap-connected with the snap-fit ​​holes 132 in a one-to-one correspondence.

[0081] That is, the support member 3 is fixed to the housing assembly by the engagement of the buckle 342 with the engagement hole 132. The engagement of the positioning protrusion 133 with the positioning engagement groove 343 effectively limits the movement of the support member 3 relative to the housing assembly in the axial direction of the fan component, thereby effectively maintaining the relative position of the support member 3 and the housing assembly, thereby improving the reliability of the support member 3 installed on the housing assembly. In addition, by providing the assembly groove 131 on the housing assembly, the impact of notching the support member 3 on the structural strength of the support member 3 can be reduced.

[0082] In some embodiments, in the axial direction of the fan component, the side surfaces on the opposite sides of the positioning protrusion 133 are respectively the first limiting surface 1331 and the second limiting surface 1332, and in the direction from the fixed end of the positioning protrusion 133 to the free end of the positioning protrusion 133, the first limiting surface 1331 and the second limiting surface 1332 extend obliquely toward each other; in the axial direction of the fan component, the inner side surfaces on the opposite sides of the positioning matching groove 343 are respectively the third limiting surface 3431 and the fourth limiting surface 3432, and the positioning matching groove 343 has an insertion port open toward the positioning protrusion 133, and in the direction toward the insertion port, the third limiting surface 3431 and the fourth limiting surface 3432 extend obliquely toward each other. Therefore, in the process of inserting the positioning protrusion 133 into the positioning matching groove 343, a good guiding effect can be formed through the cooperation of the first limiting surface 1331, the second limiting surface 1332, the third limiting surface 3431 and the fourth limiting surface 3432, so as to reduce the difficulty of aligning the positioning protrusion 133 with the positioning matching groove 343 and inserting it.

[0083] In some embodiments, the clip 342 includes an elastic arm extending along a first direction and a snap-on protrusion provided on one side of the elastic arm in a second direction. The first and second directions are both perpendicular to the axial direction of the fan component, and the first direction is perpendicular to the second direction. The snap-on hole 132 is in the shape of a thin strip extending along the axial direction of the fan component. The elastic arm is inserted into the snap-on hole 132 along the first direction. The snap-on protrusion is located on the side of the snap-on hole 132 facing away from the heat exchanger 2. In the axial direction of the fan component, the size of the snap-on hole 132 is larger than that of the clip 342. Therefore, while the positioning protrusion 133 cooperates with the positioning fit to limit the movement of the support member 3 in the axial direction of the fan component, the difficulty of inserting the clip 342 into the snap-on hole 132 can be reduced.

[0084] Furthermore, the positioning protrusion 133 and the engaging hole 132 located within the same assembly slot 131 are arranged axially along the fan component. The positioning block 341 and the adjacent engaging buckle 342 are also arranged axially along the fan component. It will be appreciated that the engaging buckle 342 is inserted into or removed from the engaging hole 132 by elastically deforming in the second direction. Therefore, the positioning block 341 is prevented from affecting the elastic deformation of the engaging buckle 342.

[0085] According to some embodiments of the present invention, Figures 22 to 25As shown, the connection structure 13 includes a support rib 134 formed on the inner wall of the second limiting groove 12. When the support member 3 is not installed in the housing assembly, the second end 22 abuts against the support rib 134, and the side of the support member 3 facing away from the second end 22 forms a limiting slot 35. When the support member 3 is installed in the housing assembly, the support rib 134 and the limiting slot 35 are plugged into and matched. Therefore, through the cooperation between the support rib 134 and the limiting slot 35, the connection position between the support member 3 and the housing assembly can be better increased, and the limiting effect of the housing assembly on the support member 3 can be improved, thereby improving the stability of the connection between the support member 3 and the housing assembly. In addition, the support rib 134 can be used to support the second end 22 of the heat exchanger 2 and to provide limiting support for the support member 3, which can increase the function of the support rib 134 and realize the reuse of the support rib 134, thereby simplifying the structure of the housing assembly.

[0086] In some embodiments, the plug-in direction of the support member 3 and the limiting slot 35 is the same as the plug-in direction of the clip 342 and the snap hole 132. Therefore, when the support member 3 is installed to the casing assembly, such as when it is installed along the plug-in direction of the support frame and the limiting slot 35, the clip 342 can also enter the snap hole 132 and snap into the snap hole 132, which can greatly reduce the difficulty of assembling the support member 3.

[0087] According to some embodiments of the present invention, a support rib 134 is formed on the inner wall of the second limiting groove 12. The support rib 134 extends axially along the fan component. When the support member 3 is not installed in the housing assembly, the second end 22 abuts against the support rib 134. In other words, the support rib 134 supports the gap between the inner wall of the second limiting groove 12 and the second end 22, thereby effectively sealing the gap between the inner wall of the second limiting groove 12 and the second end 22. Therefore, the abutment between the support rib 134 and the second end 22 ensures a sealing effect between the inner wall of the second limiting groove 12 and the heat exchanger 2, thereby preventing airflow on the upstream side of the heat exchanger 2 from directly flowing through the gap between the inner wall of the second limiting groove 12 and the second end 22 to the fan component. In other words, this ensures that airflow on the upstream side of the heat exchanger 2 passes through the heat exchanger 2 before flowing to the fan component, thereby improving the temperature regulation effect of the heat exchanger 2 on the airflow, thereby improving the heating or cooling efficiency of the air conditioner 100.

[0088] According to some embodiments of the present invention, Figures 26 to 29As shown, the support rib 134 and the inner wall of the second limiting groove 12 define a second guide groove 121 and a water receiving groove 122 located on opposite sides of the support rib 134. The water receiving groove 122 is located on the side of the support rib 134 facing the fan component. The water receiving groove 122 is suitable for communicating with the water receiving pan of the air conditioner 100. The support rib 134 is formed with a second connecting port 1341 connecting the second guide groove 121 and the water receiving groove 122. During the operation of the heat exchanger 2, when the refrigerant temperature in the heat exchanger 2 is low and the temperature of the introduced airflow is high, water droplets are easily condensed on the refrigerant pipe of the heat exchanger 2. Therefore, by providing the second guide groove 121, the condensed water on the heat exchanger 2 flows toward the second end 22 under the action of its own weight and can drip into the second guide groove 121. That is, the second guide groove 121 can catch the condensed water dripping from the second end 22 of the heat exchanger 2, and the condensed water in the second guide groove 121 can then flow into the water receiving groove 122 through the second connecting port 1341, thereby preventing the condensed water from remaining in the second guide groove 121. The water receiving groove 122 can be connected to the water receiving pan of the air conditioner 100, so that the condensed water in the water receiving groove 122 can be discharged into the water receiving pan and discharged from the air conditioner 100 through the water receiving pan.

[0089] In some embodiments, the direction in which the support rib 134 extends toward the second end 22 is perpendicular to the thickness direction of the second end 22. The support rib 134 and the second end 22 abut against each other along the circumference of the fan component. A plurality of second communication openings 1341 are provided, spaced apart along the axial direction of the fan component. The second communication openings 1341 are formed by the side of the support rib 134 facing away from the inner wall of the second limiting groove 12, and are recessed in a direction away from the second end 22. The second communication openings 1341 extend to the connection position between the support rib 134 and the inner wall of the second limiting groove 12. In addition, the height of the water receiving groove 122 is lower than the height of the second guide groove 121. Therefore, the difficulty of processing and forming the second communication opening 1341 can be reduced, ensuring that the second communication opening 1341 can drain the condensation water in the second guide groove 121 completely, thereby preventing the condensation water remaining in the second guide groove 121 from breeding bacteria and mud.

[0090] According to some embodiments of the present invention, a second sealing member 5 is provided on the inner wall of the second limiting groove 12. When the support member 3 is not installed in the housing assembly, the second sealing member 5 abuts against the second end 22. Thus, the second sealing member 5 can effectively fill the gap between the inner wall of the second limiting groove 12 and the second end 22, thereby increasing the sealing position between the inner wall of the second limiting groove 12 and the second end 22 on the basis of the support rib 134, thereby improving the sealing effect.

[0091] According to some embodiments of the present invention, the second sealing member 5 is located on the side of the support rib 134 facing away from the fan component. In other words, the sealing position between the second sealing member 5 and the second end 22 is closer to the upstream side of the second end 22 than the sealing position between the support rib 134 and the second end 22. As a result, the second sealing member 5 can effectively block airflow from flowing toward the support rib 134, further improving the sealing effect between the inner wall of the second limiting groove 12 and the second end 22.

[0092] According to some embodiments of the present invention, a second positioning surface 123 is formed on the inner wall of the second limiting groove 12, and the second sealing member 5 is disposed on the second positioning surface 123. Thus, by providing the second positioning surface 123, the installation position of the second sealing member 5 is easier to identify, thereby reducing the difficulty of positioning and installing the second sealing member 5.

[0093] In some embodiments, the second seal 5 is a sealing sponge, and the second seal 5 is adhesively connected to the second positioning surface 123. The side located on the side of the support rib 134 away from the fan component and opposite to the support 3 along the thickness direction of the second end 22 is the second side 124. The second positioning surface 123 is formed by the end of the second side 124 close to the second end 22, and extends obliquely in the direction from the support rib 134 to the second end 22 toward the direction away from the fan component, thereby making the second positioning surface 123 more obvious, so as to facilitate the installation personnel to identify and install the second seal 5.

[0094] According to some embodiments of the present invention, the support member 3 is made of a sound-absorbing material. When the support member 3 is mounted on the housing assembly, at least a portion of the support member 3 is supported between the heat exchanger 2 and the housing assembly. Therefore, by using a sound-absorbing material to manufacture the support member 3, the support member 3 can effectively absorb abnormal noise generated by thermal expansion and contraction between the support member 3, the heat exchanger 2, and the housing assembly, thereby reducing abnormal noise from the air conditioner 100 and improving the comfort of use of the air conditioner 100.

[0095] According to some embodiments of the present invention, a casing assembly includes a chassis 1 having a volute 14 formed thereon, a fan component disposed within the volute 14, the volute 14 including a front volute tongue 141 and a rear volute tongue 142. In the circumferential direction of the fan component, the end of the heat exchanger 2 proximate the front volute tongue 141 is a first end 21, and the end of the heat exchanger 2 proximate the rear volute tongue 142 is a second end 22. The chassis 1 also includes a rear panel 15 located at the rear side of the volute 14, with a connecting structure 13 formed on the rear panel 15. Therefore, by providing the connecting structure 13 on the chassis 1, it is possible to select whether to install the support member 3 according to the specifications of the heat exchanger 2. The support member 3 can accommodate the differences between heat exchangers 2 of different specifications, allowing heat exchangers 2 of different specifications to share the same chassis 1, thereby effectively reducing the number of chassis 1 specifications and lowering the production cost of the air conditioner 100.

[0096] Among them, the first limiting groove 11 is formed on the outer side of the front snail tongue 141, and the rear panel 15 and the rear snail tongue 142 jointly define a second limiting groove 12 located on the outer side of the rear snail tongue 142. In the direction from front to rear, the inner wall of the second limiting groove 12 extends upward to the rear panel 15, and the connecting structure 13 is located on the upper side of the second limiting groove 12.
