[0059] As a common household appliance, the installation of an air conditioner involves assembling numerous components. Typically, air conditioners come with a dedicated accessory package containing various small parts, such as fasteners, required for installation. These accessory packages are usually placed inside the air conditioner's packaging box.

[0060] However, this storage method has many drawbacks; firstly, it increases the complexity and cost of packaging; secondly, the fasteners are small and easily lost, which may prevent the installation from being completed properly due to the lack of fasteners, causing inconvenience to users and reducing installation efficiency.

[0061] To solve this technical problem, this utility model proposes a fresh air module 100.

[0062] Please see Figures 1 to 18 In one embodiment of this utility model, the fresh air module 100 includes a housing 10, a fresh air duct 20, and a fresh air connector 30. The housing 10 has a fresh air interface 11, and an additional structure 12 is provided outside the fresh air interface 11. The fresh air duct 20 is installed to the fresh air interface 11 through the fresh air connector 30. The fresh air connector 30 is connected to the housing 10 through a fastener 50, and the fastener 50 can also be pre-installed on the additional structure 12. This improves the installation efficiency of the fresh air module 100.

[0063] In the technical solution of this utility model, an additional structure 12 is provided on the housing 10. By pre-installing the fastener 50 onto the additional structure 12, it is not necessary to provide an accessory package for storing the fastener 50 when the fresh air module 100 leaves the factory, thereby reducing packaging complexity and packaging costs, reducing the possibility of losing the fastener 50, and ensuring the normal progress of the installation. Furthermore, when installing the fresh air connector 30 to the fresh air interface 11, the fastener 50 can be directly removed from the additional structure 12 and used for connecting the fresh air connector 30 and the housing 10, thereby further improving the installation efficiency of the fresh air module 100.

[0064] Please see Figures 2 to 7 In an embodiment of this utility model, the fresh air inlet 11 is provided with a limiting part 13, and the fresh air connector 30 includes a main body 31 and a limiting boss 32. The two ends of the main body 31 are respectively connected to the fresh air inlet 11 and the fresh air duct 20. The limiting boss 32 extends circumferentially along the outer wall of the main body 31 and overlaps the limiting part 13. In this way, the fresh air duct 20 can be inserted into the main body 31 of the fresh air connector 30 by means of connection such as interference fit or threaded connection, so as to realize the connection between the fresh air duct 20 and the fresh air connector 30. The other end of the main body 31 can be connected by the limiting boss 32 overlapping the limiting part 13. The restriction on further movement of the main body 31 serves as a notification to the installer that the fresh air connector 30 is in place and the next assembly step can be performed. It also ensures reliable connection between the main body 31 and the fresh air interface 11, allowing the fresh air duct 20 to connect with the fresh air connector 30. Furthermore, it facilitates further fixation of the fresh air connector 30 and the fresh air interface 11 based on the limit installation of the fresh air connector 30 on the fresh air interface 11. For example, it can be achieved through the limiting connection between the limiting boss 32 and the limiting part 13, or through the limiting connection between other connecting structures on the fresh air connector 30 and the housing 10. This improves the stability and ease of connection between the fresh air connector 30 and the housing 10.

[0065] Specifically, in the embodiment of this utility model, the limiting part 13 is provided with a first threaded hole 131, and the limiting boss 32 is provided with a connecting hole 321 that is opposite to the first threaded hole 131. The fastener 50 passes through the connecting hole 321 and is locked to the first threaded hole 131. At this time, the fastener 50 can be a bolt with external threads. Then, when the limiting boss 32 overlaps with the limiting part 13, the fastener 50 can pass through the connecting hole 321 through the docking of the first threaded hole 131 and the connecting hole 321, and is threaded to the first threaded hole 131 through its external threads, so as to achieve the purpose of fixing the fresh air connector 30 and the limiting part 13, and realizing the fixed connection between the fresh air connector 30 and the housing 10. In this design, the axes of the first threaded hole 131 and the connecting hole 321 coincide and are parallel to the axis of the fresh air interface 11, facilitating the installation of the fresh air connector 30 to the fresh air interface 11 and the fastener 50 to the limiting part 13 through the same through hole 421, thereby reducing assembly difficulty. However, this design is not limited to this. In other embodiments, the limiting part 13 and the limiting boss 32 can be further connected by fasteners 50 such as pins and snap fasteners.

[0066] Furthermore, the limiting boss 32 is provided with a limiting wall protruding along its periphery. The limiting wall extends toward the limiting part 13 and surrounds the periphery of the limiting part 13 when the limiting boss 32 overlaps with the limiting part 13, limiting the rotational movement of the limiting boss 32 in the circumferential direction of the fresh air interface 11. This reduces the possibility of misalignment between the limiting boss 32 and the limiting part 13 due to relative rotation, such as misalignment between the first threaded hole 131 and the connecting hole 321, thereby improving the assembly efficiency of the fresh air connector 30 at the fresh air interface 11. It can also enhance the structural strength of the limiting boss 32 to a certain extent and improve the reliability of the connection.

[0067] When the fastener 50 is configured as a bolt with external threads, specifically, in an embodiment of this utility model, the additional structure 12 is provided with a second threaded hole 121 adapted to the fastener 50. The second threaded hole 121 extends axially along the fresh air inlet 11, thus, as Figure 5 As shown, the fastener 50 is screwed onto the second threaded hole of the additional structure 12 through its external thread before leaving the factory, reducing the need for an accessory package to store the fastener 50. At the same time, it reduces the possibility of the fresh air connector 30 being unable to be installed properly due to the loss of the key fastener 50, which would hinder the installation progress or require the purchase of additional fasteners 50. This effectively improves installation efficiency and enhances the user experience.

[0068] Please refer to Figure 3Because the second threaded hole 121 of the additional structure 12 extends in the same direction as the axis of the fresh air interface 11, and the second threaded hole 121 also extends in the same direction as the axis of the first threaded hole 131, it is beneficial to improve the processing efficiency of the housing 10. At the same time, when assembling the fresh air connector 30 and the fastener 50, the same angle can be maintained, that is, the installation direction of the fresh air connector 30, the tightening direction and the loosening direction of the fastener 50 on the limiting part 13 and the additional structure 12 are all in the same direction, avoiding assembly interference caused by angle differences, such as space constraints or the inability to tilt the tool, thereby effectively improving the assembly convenience of the fresh air connector 30. Of course, the structure on the additional structure 12 for fixing the fastener 50 can be changed according to the specific structure of the fastener 50.

[0069] Please refer to Figure 2 and Figure 3 In an embodiment of this utility model, a first positioning part 14 is provided outside the fresh air interface 11. The first positioning part 14 and the limiting part 13 are arranged at intervals along the circumference of the fresh air interface 11. The fresh air connector 30 also includes a second positioning part 33 fixedly connected to the first positioning part 14. In this way, the connection strength between the fresh air connector 30 and the housing 10 can be further improved. At the same time, the connection between the first positioning part 14 and the second positioning part 33 can also improve the overlapping efficiency of the limiting boss 32 and the limiting part 13 to a certain extent.

[0070] Specifically, in the embodiments of this utility model, the included angle between the limiting part 13 and the first positioning part 14 is θ, 90°≤θ≤180°. This ensures that the fresh air connector 30 is subjected to balanced force, guaranteeing its service life and the connection strength between it and the housing 10. For optimal effect, the included angle θ between the limiting part 13 and the first positioning part 14 is 180 degrees. In this case, the second positioning part 33 and the limiting boss 32 are located on opposite sides of the main body 31, allowing for a balanced distribution of force on the fresh air connector 30. However, when the space outside the fresh air inlet 11 is limited, such as... Figure 5 As shown, the included angle between the limiting part 13 and the first positioning part 14 can be less than 180 degrees and greater than or equal to 90 degrees depending on the specific space setting, so as to ensure the force balance of the fresh air connector 30 as much as possible while reasonably designing the positional relationship between the limiting part 13 and the first positioning part 14, and extend the service life of the fresh air connector 30.

[0071] Specifically, the included angle θ between the limiting part 13 and the first positioning part 14 may take values ​​including, but not limited to, 90 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, 150 degrees, 155 degrees, 160 degrees, 165 degrees, 170 degrees, 175 degrees, and 180 degrees. In this embodiment, the included angle θ is specifically 145 degrees.

[0072] Please refer to Figure 2 , Figures 6 to 7 In this embodiment of the present invention, the first positioning part 14 is configured as a snap hole, and the second positioning part 33 is configured as an elastic snap that engages with the snap hole. Thus, through the engagement of the elastic snap and the snap, on the one hand, the housing 10 can preposition the fresh air connector 30, thereby causing the connecting hole 321 on the limiting boss 32 to quickly align with the first threaded hole 131 on the limiting part 13, facilitating the smooth passage of the fastener 50 through the limiting boss 32 and its fixed connection to the limiting part 13, achieving a quick connection between the limiting boss 32 and the limiting part 13; on the other hand, with the limiting boss 32 and the limiting part 13 further connected and fixed by the fastener 50, the fresh air connector 30 is connected to the housing 10 through the structures on both sides (the limiting boss 32 and the second positioning part 33), using multiple fixing points to enhance the connection strength between the fresh air connector 30 and the housing 10, while reducing the possibility of the elastic snap coming out of the snap hole, and improving the connection reliability between the fresh air connector 30 and the housing 10.

[0073] Specifically, a limiting groove with an opening facing the fresh air connector 30 is formed on the outer wall of the fresh air interface 11. A snap-fit ​​hole is formed in the groove wall of the limiting groove. During the assembly of the fresh air connector 30, the elastic snap enters the limiting groove through the opening and completes the pre-positioning of the fresh air connector 30 on the housing 10 when its snap protrusion engages with the snap-fit ​​hole. At this time, the limiting boss 32 is placed on the limiting part 13, and the first threaded hole 131 is aligned with the connecting hole 321. The assembly of the fresh air connector 30 at the fresh air interface 11 can be completed simply by passing the fastener 50 through the connecting hole 321 and threading it into the first threaded hole 131. However, this design is not limited to this. In other embodiments, the pre-positioning and auxiliary fixing of the fresh air connector 30 on the housing 10 can also be achieved by at least one of the first positioning part 14 and the second positioning part 33 being configured as a mounting hole and the other as a post that can be inserted into the mounting hole, and / or the first positioning part 14 and the second positioning part 33 being connected by a threaded engagement.

[0074] Please refer to Figure 2 , Figures 6 to 7In an embodiment of this utility model, the fresh air connector 30 further includes an annular rib 34. The annular rib 34 extends along the outer peripheral surface of the main body 31 and is connected to the limiting boss 32 and the second positioning part 33. The annular rib 34 abuts against the fresh air interface 11. Thus, during the process of installing the fresh air connector 30 to the fresh air interface 11, the fresh air connector 30 is moved until the annular rib 34 of the fresh air connector 30 abuts against the end of the fresh air interface 11, and the further movement of the fresh air connector 30 stops. At this time, the limiting boss 32 abuts against the limiting part 13, and the second positioning part 33 is fixedly connected to the first positioning part 14, reliably indicating to the assembler that the fresh air connector 30 has been assembled in place and the next assembly step can be carried out.

[0075] The annular rib 34 is connected to the limiting boss 32 and the second positioning part 33, which can improve the connection strength between the limiting boss 32 and the second positioning part 33 and the main body part 31 to a certain extent, and ensure the reliability and stability of the connection between the fresh air connector 30 and the shell 10.

[0076] Optionally, in an embodiment of this utility model, the main body 31 includes a first connector section 311 and a second connector section 312 connected together. The first connector section 311 is connected to the fresh air duct 20, and the second connector section 312 is sleeved outside the first connector section 311 and is provided with the limiting boss 32. The second connector section 312 is inserted into the fresh air interface 11. This makes it easy for the installer to distinguish between the first connector section 311 and the second connector section 312, and to quickly connect the second connector section 312 to the fresh air interface 11. At this time, the fresh air... The air inlet 11 may have a slot to fix the end of the second connector segment 312. A first positioning part 14 is provided on the outside of the fresh air inlet 11, which connects to the second positioning part 33 of the second connector segment 312. A limiting part 13 abuts against the limiting boss 32 of the second connector segment 312, and an annular rib 34 abuts against the end of the fresh air inlet 11, thus achieving the assembly of the fresh air connector 30 and the housing 10. This also helps ensure the structural strength and stability of the fresh air connector 30 and enhances the connection effect of the fresh air connector 30 to the fresh air duct 20 and the housing 10. However, this design is not limited to this. In other embodiments, the ends of the first connector segment 311 and the second connector segment 312 are connected, and the connection method includes, but is not limited to, welding, bonding, and integral molding.

[0077] Specifically, such as Figure 4 , Figures 6 to 7As shown in the embodiment of this utility model, a connecting rib 313 is connected between the first connector segment 311 and the second connector segment 312; and / or, a reinforcing rib 314 is connected between the first connector segment 311 and the second connector segment 312. The reinforcing rib 314 is provided in multiple circumferentially spaced along the main body 31. In this way, while ensuring the structural strength and structural stability of the fresh air connector 30, the overall weight of the fresh air connector 30 is reduced. It can also hide part of the first connector segment 311 inside the second connector segment 312, shortening the overall length of the fresh air connector 30 while extending the length of the first connecting segment 221. This increases the effective connection area between the fresh air connector 30 and the fresh air duct 20 through the first connector segment 311, thereby improving the connection reliability between the fresh air duct 20 and the fresh air connector 30.

[0078] Optionally, in order to ensure the alignment efficiency between the limiting boss 32 and the limiting part 13 and / or between the second positioning part 33 and the first positioning part 14, one of the fresh air connector 30 and the fresh air interface 11 is provided with a limiting rib 315, and the other is provided with a limiting groove 111 that guides and cooperates with the limiting rib 315. In this way, both the limiting rib 315 and the limiting groove 111 extend along the axial extension direction of the fresh air interface 11. Thus, during the process of inserting the fresh air connector 30 into the fresh air interface 11, the rotational movement of the fresh air connector 30 relative to the fresh air interface 11 can be limited by the cooperation of the limiting rib 315 and the limiting groove 111, and the fresh air connector 30 can be guided to be inserted into the fresh air interface 11, thereby improving the alignment efficiency between the limiting boss 32 and the limiting part 13, and improving the alignment efficiency between the second positioning part 33 and the first positioning part 14.

[0079] like Figure 5 and Figure 7 As shown, the limiting groove 111 is provided on the inner wall of the fresh air interface 11, and the limiting rib 315 is formed by the second connector section 312 protruding in a direction away from its axis. The limiting rib 315 can also be connected with the annular rib 34 to improve the structural stability of the limiting rib 315, thereby improving the overall structural stability of the fresh air connector 30.

[0080] The fresh air connector 30 is usually made of rigid material to ensure that the fresh air duct 20 can be quickly installed to the fresh air interface 11 through the fresh air connector 30, thereby ensuring the installation stability of the fresh air duct 20. The end of the fresh air connector 30 away from the housing 10 is used to connect the fresh air duct 20. Specifically, the first connector section 311 can be connected to the fresh air duct 20. The fresh air duct 20 is usually a flexible pipe, which makes it easy for the fresh air duct 20 to extend out of the wall to connect to the external environment, and allows the air conditioner 1 to draw fresh air from the external environment to the room through the fresh air duct 20.

[0081] Please see Figures 8 to 10In an embodiment of this utility model, the fresh air duct 20 includes a duct body 21 and a protective net 22. One end of the duct body 21 is connected to the fresh air connector 30, and the other end is fitted with the protective net 22. Thus, one end of the duct body 21 is connected to the fresh air connector 30 to realize the assembly of the fresh air duct 20 at the fresh air interface 11. The other end of the duct body 21 is provided with a protective net 22, which can prevent rats, insects or other debris from entering the room through the fresh air duct 20, thereby effectively improving the air intake effect of the fresh air duct 20 and improving the reliability of the air conditioner 1.

[0082] Specifically, in an embodiment of this utility model, the protective net 22 includes a connecting section 221 and a blocking spiral section 222. The connecting section 221 is fixed to the outer wall of the pipe body 21. The blocking spiral section 222 is connected to the connecting section 221 through a limiting section 223. The limiting section 223 extends radially along the pipe body 21. It can be understood that the connecting section 221 is fixed to the outer wall of the pipe body 2110, which can support and protect the end of the pipe body 21 away from the fresh air connector 30 to a certain extent, and realize the reliable assembly of the protective net 22. Compared to the direct connection of the blocking spiral section 222 to the connecting section 221, which causes the gap between the spirally extending blocking spiral section 222 and the outer wall of the duct body 21 to gradually increase from tangential overlap, thus causing whistling during ventilation of the fresh air duct 20, the blocking spiral section 222 is connected to the connecting section 221 through the limiting section 223. The limiting section 223 extends radially along the duct body 21 and points perpendicularly to the center, preventing the formation of a sharp-angled gap due to a gradual transition. Therefore, on the one hand, the spirally extending blocking spiral section 222 can form an air intake gap, ensuring the air intake volume of the fresh air duct 20 and reducing air intake resistance; on the other hand, it can effectively block rats and insects. To prevent debris or other foreign objects from entering the pipe body 21, the protective net 22 is protected. On the other hand, the limiting section 223 extends radially along the pipe body 21 and points perpendicularly to the center of the pipe opening. This not only eliminates the possibility of whistling caused by sharp corner gaps during ventilation of the fresh air duct 20, significantly reducing noise and improving user comfort, but also, when the connecting section 221 is installed on the outer wall of the pipe body 21, the limiting section 223, due to its extension towards the center, stops and abuts against the end of the pipe body 21, thereby limiting the installation position of the connecting section 221 on the pipe body 21 and playing a limiting role, thus achieving consistent assembly position of the protective net 22 on the pipe body 21.

[0083] Optionally, in an embodiment of this utility model, the plurality of spiral rings of the blocking spiral section 222 are gradually tapered from the pipe wall of the pipe body 21 to its center; so as to prevent rats, insects or other debris from entering the pipe body 21 through the protective net 22, improve the user experience, and at the same time reduce the air intake resistance and ensure the air intake volume of the fresh air duct 20.

[0084] The distance between the outermost spiral ring and the connecting section 221 is P1, where 3mm ≤ P1 ≤ 10mm; and / or, the distance between two adjacent spiral rings is P2, where 3mm ≤ P2 ≤ 10mm. It is understood that when the distance between the outermost spiral ring and the connecting section 221 is greater than 10mm, the excessive gap makes it difficult to prevent mice, insects, or other debris from entering the pipe body 21. When the distance between the outermost spiral ring and the connecting section 221 is less than 3mm, the insufficient gap easily increases the air intake resistance, thereby reducing the air intake volume of the fresh air duct 20. Furthermore, when the distance between two adjacent spiral rings is large... When the gap is 10mm, it is too large and not conducive to preventing mice, insects or other debris from entering the pipe body 21. When the gap between two adjacent spiral rings is less than 3mm, the air intake resistance is too small and the air intake volume of the fresh air duct 20 is reduced. Therefore, the gap between the outermost spiral ring and the connecting section 221 is reasonably designed to be between 3mm and 10mm, and the gap between two adjacent spiral rings is reasonably designed to be between 3mm and 10mm. This ensures that the protective net 22 can take into account both the function of reducing air intake resistance and the protective function, thereby ensuring the air intake volume of the fresh air duct 20, improving the freshness of indoor air, and improving the user experience.

[0085] Specifically, the distance P1 between the outermost threaded ring and the connecting section 221 can take values ​​including, but not limited to, 3mm, 3.8mm, 4mm, 4.9mm, 5mm, 5.5mm, 6mm, 6.4mm, 7mm, 8mm, 8.5mm, 9mm, 9.5mm, and 10mm. However, this design is not limited to this. In other embodiments, the distance P1 between the outermost threaded ring and the connecting section 221 is greater than 10mm and less than or equal to 13mm.

[0086] The specific values ​​of the spacing P2 between two adjacent threaded rings include, but are not limited to, 3mm, 3.8mm, 4mm, 4.9mm, 5mm, 5.5mm, 6mm, 6.4mm, 7mm, 8mm, 8.5mm, 9mm, 9.5mm, and 10mm. However, this design is not limited to these values. In other embodiments, the spacing P2 between two adjacent threaded rings is greater than 10mm and less than or equal to 13mm. Further, in one embodiment of this utility model, the spacing P1 between the outermost threaded ring and the connecting section 221 is between 4mm and 8.5mm, and the spacing P2 between two adjacent threaded rings is between 4mm and 8.5mm.

[0087] Optionally, in an embodiment of this utility model, the outer wall of the pipe body 21 is provided with a rib 211 extending spirally along its length direction, and the connecting segment 221 is wound around the pipe body 21 and located in the groove formed by the pipe body 21 and the rib 211; it can be understood that the protective net 22 can be formed by spiraling a single metal wire, or the connecting segment 221, the limiting segment 223, and the blocking spiral segment 222 can be welded into a whole to ensure the comprehensive performance and elasticity of the protective net 22 and improve the protective effect and service life of the protective net 22.

[0088] Because the outer wall of the pipe body 21 is provided with ribs 211 extending spirally along the length of the pipe body 21, the pipe body 21 is a pipe body 21 with external threads, and two adjacent threads together with the outer wall of the pipe body 21 form a groove extending spirally along the length of the pipe body 21, which helps to enhance the structural strength of the pipe body 21. The connecting section 221 is wound around the outer wall of the pipe body 21 to form a spiral structure. The spiral line of this spiral structure is adapted to the pipe body 21, and when the pipe body 21 is a round pipe, it is configured as a cylindrical spiral line. At this time, the connecting section 221 is rotated along the groove to the outer wall of the pipe body 21. While the connecting section 221 is limited and installed in the groove, the rotation stops when the limiting section 223 stops and abuts against the end of the pipe body 21. Compared with rotating by feel, which leads to differences in the screw-in position, the setting of the limiting section 223 can improve the consistency of the screw-in position, improve the assembly efficiency and assembly position consistency of the protective net 22 and the pipe body 21. However, this design is not limited to this. In other embodiments, the outer wall of the pipe body 21 is provided with a fastener for the connecting section 221 to pass through. By the cooperation between the connecting section 221 and the fastener, or by the interference fit between the pipe body 21 and the connecting section 221, the installation of the protective net 22 on the pipe body 21 can also be achieved.

[0089] Optionally, in an embodiment of the present invention, the outer wall of the pipe body 21 is provided with a rib 211 extending spirally along its length direction, and one end of the pipe body 21 is threadedly connected to the fresh air connector 30 through the rib 211. At this time, a spiral groove adapted to the rib 211 is formed in the fresh air connector 30, so as to realize the assembly of the fresh air pipe 20 and the fresh air connector 30.

[0090] Optionally, in an embodiment of the present invention, the pitch of the thread at any position on the connecting segment 221 is equal; this arrangement facilitates the processing of the ribs 211 on the pipe body 21 and can also ensure the overall rigidity and stability of the connecting segment 221, thereby improving the reliability of the protective net 22 connected to the pipe body 21 through the connecting segment 221.

[0091] The pitch of the connecting segment 221 is P3, where P3 ≥ 10mm. Specifically, the pitch of the connecting segment 221 can take values ​​including, but not limited to, 10mm, 10.5mm, 11mm, 11.8mm, and 12mm. The number of turns of the connecting segment 221 can be limited to between 3 and 6 turns to ensure the connection between the connecting segment 221 and the pipe body 21. However, this design is not limited to this. In other embodiments, the pitch of the connecting segment 221 is greater than 10mm and less than or equal to 15mm. In one embodiment of this utility model, the pitch of the connecting segment 221 is 10mm and the number of turns is 4, so as to ensure the connection between the connecting segment 221 and the pipe body 21 while reasonably reducing the number of turns to improve assembly efficiency and save costs.

[0092] This utility model also proposes an air conditioner 1, which includes a chassis and a fresh air module 100. The specific structure of the fresh air module 100 is as described in the above embodiments. Since this air conditioner 1 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The fresh air module 100 is located on the chassis, enabling the air conditioner 1 to have a fresh air mode. In this mode, fresh air is supplied to the indoor environment through the fresh air duct 20 to improve the freshness of the indoor air and enhance user comfort.

[0093] It should be noted that air conditioner 1 can specifically be a wall-mounted air conditioner 1, a portable air conditioner 1, a cabinet air conditioner 1, or any other air conditioner 1 with a fresh air mode. The following description will take the configuration of air conditioner 1 as a wall-mounted indoor unit as an example.

[0094] Specifically, please refer to Figures 11 to 18 The air conditioner 1 includes a chassis and a front frame 43 covering the chassis. The fresh air module 100 is installed at the end of the chassis, specifically on the right side of the chassis. Thus, the air outlet of the fresh air module 100 is connected to the outlet on the front frame 43, so that the air conditioner 1 sends fresh air forward to the indoor environment. The fresh air interface 11 of the fresh air module 100 is connected to the fresh air duct 20 through the fresh air connector 30. The fresh air duct 20 passes through the back of the air conditioner 1 and the wall to connect to the outside environment.

[0095] Specifically, in an embodiment of this utility model, the chassis is provided with an installation cavity 411 and a through hole 421 communicating with the installation cavity 411. The fresh air module 100 is installed in the installation cavity 411, and the fresh air interface 11 is exposed in the through hole 421. Thus, the fresh air module 100 can be installed into the installation cavity 411 by means of screw connection, snap-fit ​​connection, etc., and the fresh air interface 11 of the fresh air module 100 is exposed through the through hole 421. This facilitates the installation of structures such as the fresh air duct 20 and the fresh air connector 30 through the through hole 421 to the fresh air interface 11, thereby improving the efficiency and convenience of disassembly and assembly of the air conditioner 1.

[0096] Please see Figure 16 and Figure 18 In an embodiment of this utility model, the chassis includes a chassis cover plate 42 with the through hole 421 formed thereon. The diameter of the through hole 421 is larger than the size of the fresh air connector 30. It can be understood that the chassis includes a chassis body 41 and a chassis cover plate 42. The chassis body 41 has an installation cavity 411 for installing the fresh air module 100. The chassis cover plate 42 is fixed to the chassis body 41 by means of snap-fit ​​connection or the like, and has the through hole 421 formed thereon. The size of the through hole 421 is larger than the size of the fresh air connector 30. This facilitates the smooth passage of the fresh air connector 30 through the through hole 421, so as to realize the assembly of the fresh air connector 30 at the fresh air interface 11.

[0097] Please see Figure 14 In an embodiment of this utility model, the chassis includes a chassis cover plate 42 with the through hole 421 formed thereon. The fresh air connector 30 is provided with an installation position for fasteners 50. The distance from the installation position to the edge of the chassis cover plate 42 near the back of the air conditioner 1 is K, where K < 150 mm. This ensures that tools used for disassembling and assembling fasteners 50, such as bolts, can reach the installation position, thus achieving a secure assembly of the fasteners 50 with the fresh air connector 30 and the housing 10. Specifically, the specific values ​​of the distance from the installation position to the edge of the chassis cover plate 42 near the back of the air conditioner 1 include, but are not limited to, 50 mm, 65 mm, 70 mm, 85 mm, 90 mm, 100 mm, 110 mm, and 120 mm. In one embodiment of this utility model, the distance from the installation position to the edge of the chassis cover plate 42 near the back of the air conditioner 1 is 82mm. This can make reasonable use of the space inside the chassis, hide the fresh air connector 30 and the connection between the fresh air connector 30 and the fresh air duct 20, and at the same time improve the ease of installation and removal of the fresh air duct 20 and the fresh air connector 30 to the fresh air interface 11.

[0098] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
