[0002] This application claims priority to Chinese patent applications filed on December 13, 2024, with application number 202411845495.8 entitled "Indoor unit, air conditioner and maintenance method" and application number 202423091952.7 entitled "Indoor unit and air conditioner", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of air conditioning technology, and in particular to an indoor unit, an air conditioner, and a maintenance method. Background Technology

[0004] The indoor unit of an air conditioner includes a heat exchange component and an air supply component. The air supply component generates airflow that exchanges heat with the heat exchange component. The air supply component includes a fan impeller, and the heat exchange component includes a heat exchanger, which is arranged around the fan impeller. In related technologies, when the fan impeller needs to be inspected or cleaned, the heat exchange component must first be removed to avoid creating the space required for fan impeller removal, making the fan impeller removal process rather cumbersome. Summary of the Invention

[0005] The main purpose of this application is to provide an indoor unit, an air conditioner, and a maintenance method that facilitates the disassembly of the fan impeller.

[0006] To achieve the above objectives, this application proposes an indoor unit, the indoor unit comprising:

[0007] Housing assembly, the housing assembly including a chassis;

[0008] A heat exchanger is connected to the chassis, and the heat exchanger and the chassis together form a receiving space. The heat exchanger includes a first end that is detachably connected to the chassis, and the first end and the chassis together form a first opening communicating with the receiving space.

[0009] A fan, disposed within the receiving space, is used to generate an airflow for heat exchange with the heat exchanger; and

When the auxiliary component is in the first mounting position, it is detachably connected to the housing assembly. When the auxiliary component is in the second mounting position, it is disposed between the first end and the chassis.

[0011] The auxiliary component is configured to be able to switch to the second mounting position after being at least partially detached from the chassis at the first end, so as to support the first end and increase the size of the first opening, thereby allowing the wind turbine to be detached from the receiving space at the first opening.

[0012] In some embodiments, the heat exchanger includes a heat exchange body and a support member connected to one end of the heat exchange body, the first end including the support member, the support member being detachably connected to the chassis, the support member being disposed around the outer periphery of the first opening; and, when the auxiliary member is disposed in the second installation position, it is located between the support member and the chassis and supports the support member.

[0016] In some embodiments, the chassis has a first recess communicating with the first opening at the first opening, the indoor unit includes a rotating member at least partially disposed in the first recess, the fan wheel includes a rotating shaft, the rotating shaft being rotatably connected to the chassis via the rotating member; and the auxiliary member has a second recess, the auxiliary member abutting against the side of the rotating member away from the chassis when the auxiliary member is in the first installation position, and the rotating member being at least partially disposed in the second recess.

[0017] In some embodiments, a retaining edge is provided on the side of the first end facing the first opening, and the side of the auxiliary member facing the receiving space abuts against the retaining edge when the auxiliary member is in the first mounting position.

[0018] In some embodiments, the first end includes a first abutment portion, and when the auxiliary member is located in the first mounting position, the first abutment portion extends at the outer periphery of the auxiliary member to the side of the auxiliary member opposite to the receiving space, and the end of the first abutment portion opposite to the receiving space abuts against the side wall of the auxiliary member opposite to the receiving space.

[0019] In some embodiments, the auxiliary member includes a second abutment portion. When the auxiliary member is in the first mounting position, the second abutment portion extends in a direction away from the receiving space to the side of the first end opposite to the receiving space, and the end of the second abutment portion opposite to the receiving space abuts against the side wall of the first end opposite to the receiving space.

[0020] In some embodiments, the heat exchanger is configured to be detached from the chassis along a first direction, with a second direction perpendicular to the first direction; and the auxiliary component is provided with a first connecting structure, the chassis is provided with a second connecting structure, and when the auxiliary component is in the second mounting position, the first connecting structure is connected to the second connecting structure to limit relative sliding between the auxiliary component and the chassis along the second direction.

[0021] In some embodiments, the first connecting structure includes a first slot, the second connecting structure includes a first protrusion, and when the auxiliary component is located in the second mounting position, the first protrusion is at least partially engaged in the first slot along the second direction.

[0022] In some embodiments, the first connecting structure includes a second protrusion and a third protrusion spaced apart from each other, the gap between the second protrusion and the third protrusion forming the first slot; the auxiliary member is connected to the chassis and at least partially covers the first opening when it is in the first mounting position; the auxiliary member includes a second abutment portion, which extends in a direction away from the receiving space to the side of the first end opposite to the receiving space when the auxiliary member is in the first mounting position, and the end of the second abutment portion opposite to the auxiliary member abuts against the sidewall of the first end opposite to the receiving space; and at least one of the second protrusion and the third protrusion is the second abutment portion.

[0024] In some embodiments, when the first end is connected to the chassis, the size of the first opening is smaller than the minimum detachment size of the wind turbine; when the first end is at least partially detached from the chassis and the auxiliary component is located in the second mounting position, the size of the first opening is larger than the minimum detachment size of the wind turbine.

[0025] A second aspect of this application also provides an air conditioner, comprising:

[0026] The indoor unit described in any of the above embodiments; and

[0027] Outdoor unit, connected to the outdoor unit.

[0028] A third aspect of this application also provides a maintenance method for the indoor unit described in any of the above embodiments, the maintenance method comprising:

[0029] Disassemble the first end;

[0030] Remove the auxiliary component located at the first installation position;

[0031] Install the auxiliary component in the second installation position; and

[0032] Disassemble the wind turbine and detach it from the receiving space at the first opening.

[0033] Compared with the prior art, the beneficial effects of this application are:

[0034] In the technical solution of this application, the auxiliary component has a first mounting position and a second mounting position. When located in the first mounting position, it is detachably connected to the housing assembly. When located in the second mounting position, it is positioned between the first end and the chassis to support the first end and increase the size of the first opening, thereby facilitating the removal of the impeller from the first opening to accommodate the space. In other words, in this solution, when the impeller needs to be removed, it is not necessary to completely disassemble the entire heat exchanger. Only the first end of the heat exchanger needs to be removed, and the first end is driven to move away from the chassis to increase the size of the first opening, making the size of the first opening large enough for the impeller to be removed. Compared with related technologies that require complete removal of the heat exchanger for subsequent operations on the impeller, the solution of this application has fewer operation steps and higher operational efficiency.

[0035] Furthermore, in this solution, after the operator drives the first end to move away from the chassis until the size of the first opening is suitable for the disassembly of the wind turbine, the auxiliary component can be locked between the chassis and the first end (even if the auxiliary component is in the second installation position), thereby keeping the size of the first opening within a suitable range. Compared to the method where the operator supports the first end with one hand to maintain the size of the first opening and disassembles the wind turbine with the other hand, this solution does not require manual support of the first end, so the operator can operate the disassembly of the wind turbine with both hands, making the operation more convenient.

[0050] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0051] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0052] The indoor unit of an air conditioner includes a heat exchange component and an air supply component. The air supply component generates airflow that exchanges heat with the heat exchange component. The air supply component includes a fan wheel, and the heat exchange component includes a heat exchanger, which is arranged around the fan wheel. In related technologies, when the fan wheel needs to be inspected or cleaned, the heat exchange component must first be removed to make room for the fan wheel removal, which makes the fan wheel removal process cumbersome. In one improved solution, the applicant attempted to remove only one end of the heat exchanger when removing the fan wheel, and then remove the fan wheel through a hole at the removed end of the heat exchanger. However, in the above solution, the operator needs to use one hand to drive the removed end of the heat exchanger away from the chassis (since the other end of the heat exchanger is not removed, the heat exchanger undergoes a small elastic deformation at this time) to make the size of the hole at the removed end of the heat exchanger suitable for the removal of the fan wheel. However, in the above solution, the operator needs to use one hand to support the removed end of the heat exchanger to keep the hole size appropriate, and use the other hand to complete the removal of the fan wheel, which is inconvenient.

[0053] Please refer to Figures 1 to 11. An embodiment of this application provides an indoor unit 100, which is applicable to an air conditioner 10, including but not limited to window air conditioners, wall-mounted air conditioners, and floor-standing air conditioners. Please refer to Figures 1 to 3. The indoor unit 100 includes a housing assembly 110, a heat exchanger 120, a fan impeller 130, and auxiliary components 140. The housing assembly 110 includes a chassis 111, and the heat exchanger 120 is connected to the chassis 111, together forming a receiving space 112. The heat exchanger 120 includes a first end 121 detachably connected to the chassis 111, and the first end 121 and the chassis 111 together form a first opening 122 communicating with the receiving space 112. It should be noted that the heat exchanger 120 also includes a second end disposed opposite to the first end 121, and the second end and the chassis 111 together form a second opening communicating with the receiving space 112. The impeller 130 is disposed within the receiving space 112 and is used to generate airflow for heat exchange with the heat exchanger 120. The auxiliary component 140 has a first mounting position 141 and a second mounting position 142. When the auxiliary component 140 is in the first mounting position 141, it is detachably connected to the housing assembly 110. When the auxiliary component 140 is in the second mounting position 142, it is disposed between the first end 121 and the chassis 111.

[0054] Specifically, referring to Figures 1 and 4, the auxiliary component 140 is configured to be switchable to a second mounting position 142 after the first end 121 is at least partially detached from the chassis 111. This position supports the first end 121 and increases the size of the first opening 122, allowing the impeller 130 to be disassembled from the first opening 122 to access the receiving space 112. This design makes the disassembly and maintenance of the impeller 130 more convenient, improving equipment maintenance efficiency and user experience. Compared to related technologies, where the entire heat exchanger 120 needs to be completely removed when inspecting internal structures such as the fan blades of the air conditioner 10, the auxiliary component 140 in this solution allows the impeller 130 to be removed without completely removing the heat exchanger 120 during maintenance, facilitating maintenance and other operations. In another related technology, during the maintenance of the air conditioner 10, it is not necessary to completely remove the heat exchanger 120. Instead, one end of the heat exchanger 120 can be lifted manually, allowing maintenance personnel to remove or repair structures such as fan blades through the lifted end of the heat exchanger 120. However, due to the size of the air conditioner 10 and the suspended nature of some installation positions, the operation of the air conditioner 10 by maintenance personnel is very limited. Moreover, the maintenance end of the air conditioner 10 cannot accommodate multiple people for operation. This forces maintenance personnel to lift the heat exchanger 120 with one hand and remove or repair structures such as fan blades with one hand, which is very inconvenient and extremely dangerous (the maintenance personnel at the height have both hands occupied, making it difficult to maintain their balance and easy to fall and get injured). Compared with related technologies, this application supports the first end 121 of the heat exchanger 120 by using an auxiliary component 140 that can be detached from the chassis 111 and switched to the second installation position 142, thereby increasing the size of the first opening 122. As a result, maintenance personnel do not need to exert effort to support the heat exchanger 120 when inspecting or disassembling the impeller 130, thus improving maintenance convenience, reducing maintenance difficulty, and improving maintenance safety.

[0055] It should be noted that during the maintenance of the air conditioner 10, the first end 121 of the heat exchanger 120 can be detached from the base, while the second end can remain connected to the base, ensuring that the first end 121 can move relative to the base around the second end. Specifically, the connecting bolts or other connecting structures of the first end 121 of the heat exchanger 120 can be removed to allow the first end 121 to separate from the base, and the connecting bolts or other connecting structures of the second end can be loosened, for example, by loosening the connecting bolts. This allows the first end 121 to move relative to the base around the second end under the action of the auxiliary component 140, thereby increasing the size of the first opening 122.

[0056] It is understood that in some embodiments, the auxiliary component 140 can employ various structures to achieve its function. For example, the auxiliary component 140 can be designed with a flexible support arm, allowing the user to easily switch it from a first mounting position 141 to a second mounting position 142. The flexible support arm design not only provides stable support but also facilitates fine-tuning by the user, ensuring the stability of the first end 121 during disassembly. Furthermore, the auxiliary component 140 can be made of high-strength aluminum alloy or plastic to ensure its durability and reliability during use.

[0057] In another embodiment, the auxiliary component 140 can be designed with a locking mechanism. For example, the auxiliary component 140 can be equipped with a locking screw, which the user can tighten or loosen to fix or release the position of the auxiliary component 140, thereby achieving quick installation and disassembly. This locking mechanism is not only easy to operate but also has high stability and reliability. To further improve the user's operating experience, the surface of the auxiliary component 140 can be designed with an anti-slip texture to increase friction and prevent the user from slipping during operation.

[0058] Furthermore, the auxiliary component 140 can be designed with multiple installation methods. For example, the auxiliary component 140 can be equipped with multiple different types of mounting holes or slots, allowing users to choose the appropriate installation method according to their actual needs. This multi-functional design not only improves the compatibility of the equipment but also provides users with more choices to meet different installation requirements.

[0059] Referring to Figure 3, in some embodiments, the heat exchanger 120 includes a heat exchange body 123 and a support member 124 connected to one end of the heat exchange body 123. The first end 121 includes the support member 124, which is detachably connected to the chassis 111 and is arranged around the outer periphery of the first opening 122. It should be noted that in some embodiments, the support member 124 may cover half of the circumference of the outer periphery of the first opening 122, or the support member 124 may cover three-quarters of the circumference of the outer periphery of the first opening 122, etc., all of which can be considered as the support member 124 being arranged around the outer periphery of the first opening 122. When the auxiliary member 140 is located in the second mounting position 142, it is located between the support member 124 and the chassis 111 and supports the support member 124. The support member 124 provides effective support for the heat exchanger body 123 while ensuring its secure installation. When positioned in the second installation position 142, the auxiliary member 140 is located between the support member 124 and the base, providing support for the support member 124. This not only improves the stability of the heat exchanger 120 but also ensures effective support for the heat exchanger body 123 during disassembly, preventing damage to the heat exchanger body 123 caused by the auxiliary member 140 while supporting it, and avoiding damage due to improper disassembly. In this way, users can easily disassemble the impeller 130 without damaging the heat exchanger 120, improving equipment maintenance efficiency and user experience.

[0060] Understandably, in some embodiments, the support member 124 may be provided with reinforcing ribs, which can improve the strength and stability of the support member 124. The design of the reinforcing ribs not only provides higher structural strength but also facilitates fine-tuning by the user, ensuring that the support member 124 remains stable during disassembly. In addition, the support member 124 can be made of high-strength stainless steel or aluminum alloy to ensure its durability and reliability during use.

[0061] In another embodiment, the support member 124 can be designed with a cushioning pad. For example, the bottom of the support member 124 (the side closest to the base) can be provided with a rubber pad or other cushioning material. The cushioning pad reduces hard contact between the support member 124 and the chassis 111, thereby reducing noise and vibration. This cushioning design not only improves the operational stability of the equipment but also provides a quieter operating environment for the user. To further improve the user's ease of maintenance, the surface of the support member 124 can be designed with an anti-slip texture to increase friction and prevent the user from slipping during operation.

[0062] In some embodiments, the support member 124 includes an upper support end 1241 and a lower support end 1242, both of which are detachably connected to the chassis 111. When the auxiliary member 140 is in the second mounting position 142, the lower support end 1242 is detached from the chassis 111, and the auxiliary member 140 can be positioned between the lower support end 1242 and the chassis 111 to support the lower support end 1242. In some embodiments, the upper support end 1241 is detachably hinged to the base and can rotate relative to the base. When the lower support end 1242 is detached from the base, the lower support end 1242 can rotate relative to the base around the upper support end 1241, thereby increasing the distance between the lower support end 1242 and the base, so that the auxiliary member 140 can be inserted between them, thereby providing support for the support member 124 and increasing the size of the first opening 122. In other embodiments, the upper support end 1241 may also be detachably connected to the base by a threaded fastener. After the lower support end 1242 is removed from the base, the threaded fastener connecting the upper support end 1241 to the base can be completely removed or the threaded fastener can be loosened so that the support 124 can move relative to the base.

[0063] Specifically, when the wind turbine 130 needs to be disassembled or maintained, the user can first remove the lower support end 1242 from the chassis 111, and then switch the auxiliary component 140 to the second mounting position 142, thereby supporting the lower support end 1242 and increasing the size of the first opening 122, allowing the wind turbine 130 to be smoothly disassembled from the first opening 122 and placed into the receiving space 112. This method not only improves the maintenance efficiency of the equipment, but also ensures the safety and stability of operation.

[0064] Understandably, in some embodiments, the upper support end 1241 and the lower support end 1242 may be designed with threaded holes, allowing the user to fasten them to the chassis 111 using screws. This threaded connection design not only provides higher connection strength but also facilitates fine-tuning by the user, ensuring precise alignment of the support member 124. Furthermore, the upper support end 1241 and the lower support end 1242 may be made of high-strength stainless steel or aluminum alloy to ensure durability and reliability during use.

[0065] In another embodiment, the auxiliary component 140 can be designed as a structure with dual support functions. For example, the auxiliary component 140 includes a first support portion and a second support portion. When the auxiliary component 140 is in the second mounting position 142, both the upper support end 1241 and the lower support end 1242 are detached from the chassis 111. The first support portion is located between the upper support end 1241 and the chassis 111 to support the upper support end 1241, and the second support portion is located between the lower support end 1242 and the chassis 111 to support the lower support end 1242. This dual support design not only improves the stability of the support component 124 but also ensures the safety and reliability of the entire heat exchanger 120 during disassembly. To further improve the user's operating experience, the surface of the auxiliary component 140 can be designed with an anti-slip texture to increase friction and prevent the user from slipping during operation. In some embodiments, the first support portion and the second support portion can be interconnected and can be assembled into one unit. In other embodiments, the first support portion and the second support portion can be two separate independent structures.

[0066] Referring to Figure 1, in some embodiments, when the auxiliary component 140 is in the first mounting position 141, it is connected to the chassis 111 and at least partially covers the first opening 122. This design allows the auxiliary component 140 to protect the first opening 122 when not in use, without affecting the normal operation of the indoor unit 100. When it is necessary to disassemble or maintain the impeller 130, the user can switch the auxiliary component 140 from the first mounting position 141 to the second mounting position 142, thereby supporting the first end 121 and increasing the size of the first opening 122, allowing the impeller 130 to be easily disassembled out of the receiving space 112. This method not only improves the maintenance efficiency of the equipment but also ensures the safety and stability of operation.

[0067] It is understood that in some embodiments, the auxiliary component 140 can employ various structures to achieve its function. For example, the auxiliary component 140 can be designed with a snap-fit ​​structure, allowing the user to secure it to the chassis 111 through a simple snap-fit ​​operation. The snap-fit ​​design is not only easy to operate but also offers high stability and reliability. To further enhance the user experience, the snap-fit ​​can be designed with a spring, allowing the user to quickly unlock the auxiliary component 140 by pressing or pulling it, enabling rapid disassembly.

[0068] In another embodiment, the auxiliary component 140 can be designed with a sealing strip. For example, the edge of the auxiliary component 140 can be provided with a rubber sealing strip, which can fit tightly around the first opening 122 when the auxiliary component 140 is in the first mounting position 141, preventing dust and debris from entering the receiving space 112. This sealing design not only improves the protective performance of the device, but also provides a cleaner operating environment for the user.

[0069] The design of the auxiliary component 140, which partially covers the first opening 122 in the first installation position 141, is based on two main considerations: first, to provide a physical barrier to prevent external objects from entering the receiving space 112; and second, to maintain an overall aesthetically pleasing and compact design, without affecting the appearance and layout of the indoor unit 100. When the auxiliary component 140 is switched to the second installation position 142, it plays a crucial supporting role, ensuring the stability of the first end 121 (i.e., the support component 124) during disassembly, preventing damage caused by gravity or other external forces. This design greatly simplifies the disassembly process of the fan wheel 130, improves maintenance efficiency, reduces maintenance costs and technical difficulty, and enhances the user experience. Through the design of the auxiliary component 140, the indoor unit 100 not only achieves efficient and convenient maintenance operations but also ensures the reliability and safety of the equipment during daily operation.

[0070] Referring to Figures 3 and 4, in some embodiments, the chassis 111 of the indoor unit 100 has a first cavity 1111 communicating with the first opening 122. The indoor unit 100 includes a rotating member 150 at least partially disposed in the first cavity 1111, and the impeller 130 includes a rotating shaft 131, which is rotatably connected to the chassis 111 via the rotating member 150. The auxiliary member 140 has a second cavity 143. When the auxiliary member 140 is in the first mounting position 141, it can abut against the side of the rotating member 150 away from the chassis 111, and the rotating member 150 is at least partially disposed within the second cavity 143 of the auxiliary member 140. Thus, the auxiliary member 140 not only covers and protects the first opening 122, but also supports and positions the rotating member 150. By placing the rotating component 150 within the first recess 1111 and the second recess 143 of the auxiliary component 140, the stability and rotational accuracy of the impeller 130 shaft 131 are ensured, thereby improving the reliability and efficiency of the impeller 130's operation. Furthermore, the close cooperation between the auxiliary component 140 and the rotating component 150 reduces vibration and noise, enhancing the user experience. Specifically, during normal use of the air conditioner 10, the auxiliary component 140 protects the first opening 122, eliminating the need for additional protective components for the first opening 122 and reducing material costs. During maintenance of the air conditioner 10, the auxiliary component 140 can be detached from the first opening 122 and positioned between the base and the first end 121, providing support for the heat exchanger 120. At this time, the auxiliary component 140 is firmly positioned between the heat exchanger 120 and the base due to the interaction force between them, effectively preventing loss, saving reassembly time after maintenance, and improving maintenance efficiency.

[0071] It is understood that in some embodiments, the rotating component 150 can employ various structures to achieve its function. For example, the rotating component 150 can be designed with a bearing structure, which allows the user to improve the rotational accuracy and stability of the rotating component 150. The bearing design not only provides higher rotational freedom but also reduces friction and lowers energy consumption. To further improve the user's operating experience, the surface of the rotating component 150 can be designed with an anti-slip texture to increase friction and prevent the user from slipping during operation.

[0072] In another embodiment, the first cavity 1111 and the second cavity 143 can be designed with sealing strips. For example, rubber sealing strips can be provided on the edges of the first cavity 1111 and the second cavity 143. When the auxiliary component 140 is in the first mounting position 141, the sealing strips can fit tightly around the rotating component 150 to prevent dust and debris from entering the accommodating space 112. This sealing design not only improves the protective performance of the device but also provides a cleaner operating environment for the user.

[0073] Referring to Figure 9, in some embodiments, a retaining edge 1211 is provided on the side of the first end 121 facing the first opening 122. When the auxiliary component 140 is in the first mounting position 141, its side facing the receiving space 112 abuts against the retaining edge 1211. This design allows the auxiliary component 140 to be securely fixed between the first end 121 and the chassis 111 in the first mounting position 141, while covering part of the first opening 122 to prevent external foreign objects from entering the receiving space 112. In addition, the auxiliary component 140 can also provide support for the heat exchanger 120, improving the structural stability of the indoor unit 100. The design of the retaining edge 1211 not only improves the installation accuracy of the auxiliary component 140, but also ensures its stability during use.

[0074] Specifically, the retaining edge 1211 can form a stable contact surface between the first end 121 and the auxiliary component 140, preventing the auxiliary component 140 from loosening or shifting due to vibration or other external forces. In this way, the indoor unit 100 not only achieves efficient and convenient maintenance operations, but also ensures the reliability and safety of the equipment in daily operation.

[0075] It is understood that in some embodiments, the retaining edge 1211 can employ various structures to achieve its function. For example, the retaining edge 1211 can be provided with an elastic pad, which allows the user to increase the contact area and friction between the retaining edge 1211 and the auxiliary component 140, ensuring the stable installation of the auxiliary component 140. The design of the elastic pad not only provides a better sealing effect but also reduces vibration and noise, improving the user experience. To further improve the user's operating experience, the surface of the retaining edge 1211 can be designed with an anti-slip texture to increase friction and prevent the user from slipping during operation.

[0076] In another embodiment, the retaining edge 1211 can be designed with a snap-fit ​​structure. For example, the retaining edge 1211 can be provided with a slot or hook, allowing the user to securely fix the auxiliary component 140 to the first end 121 using the snap-fit. This snap-fit ​​design is not only easy to operate but also has high stability and reliability. To further improve the user experience, the snap-fit ​​can be designed with a spring, allowing the user to quickly unlock the auxiliary component 140 by pressing or pulling the snap-fit, achieving quick disassembly. In some embodiments, the connection between the retaining edge 1211 and the auxiliary component 140 can also be achieved using threaded fasteners. Specifically, both the retaining edge 1211 and the auxiliary component 140 are provided with threaded holes, and bolts or screws are inserted into the threaded holes and tightened to achieve the connection between the two.

[0077] Furthermore, the retaining edge 1211 can also be designed with multiple guiding functions. For example, the retaining edge 1211 can be provided with guide rails or guide grooves, allowing the user to accurately install the auxiliary component 140 into the first installation position 141. This guiding design not only improves installation accuracy but also simplifies the user's operation steps and increases work efficiency. To further improve the portability and ease of use of the equipment, the retaining edge 1211 can also be designed with an adjustable structure, allowing for easy adjustment to accommodate auxiliary components 140 of different sizes, further enhancing the equipment's compatibility and flexibility.

[0078] Referring to Figure 9, in some embodiments, the first end portion 121 includes a first abutment portion 1212. When the auxiliary member 140 is in the first mounting position 141, the first abutment portion 1212 extends from the outer periphery of the auxiliary member 140 to the side of the auxiliary member 140 facing away from the receiving space 112, and the end of the first abutment portion 1212 facing away from the receiving space 112 abuts against the side wall of the auxiliary member 140 facing away from the receiving space 112. Specifically, the first abutment portion 1212 can serve as a guide and limiter, ensuring that the auxiliary member 140 can be firmly fixed to the first end portion 121 in the first mounting position 141, preventing it from loosening or shifting due to vibration or other external forces. The presence of the first abutment portion 1212 not only improves the installation accuracy of the auxiliary member 140, but also enhances its stability during use.

[0079] It is understood that in some embodiments, the first abutment 1212 can employ various structures to achieve its function. For example, the first abutment 1212 can be designed with an elastic pad, which allows the user to increase the contact area and friction between the first abutment 1212 and the auxiliary member 140, ensuring the stable installation of the auxiliary member 140. The elastic pad design not only provides a better sealing effect but also reduces vibration and noise, improving the user experience. In some embodiments, the first abutment 1212 is connected to the retaining edge 1211, and the auxiliary member 140 can be located between the first abutment 1212 and the retaining edge 1211 to facilitate the connection between the auxiliary member 140 and the first end 121.

[0080] Referring to Figures 2 and 11, in some embodiments, the auxiliary member 140 includes a second abutment 144. When the auxiliary member 140 is in the first mounting position 141, the second abutment 144 extends away from the receiving space 112 to the side of the first end 121 opposite to the receiving space 112, and the end of the second abutment 144 opposite to the receiving space 112 abuts against the side wall of the first end 121 opposite to the receiving space 112. This design allows the auxiliary member 140 to be securely fixed between the first end 121 and the chassis 111 in the first mounting position 141, preventing it from loosening or shifting. The presence of the second abutment 144 not only improves the installation accuracy of the auxiliary member 140 but also enhances its stability during use. In some embodiments, the connection between the second abutment 144 and the first end 121 and / or the base includes, but is not limited to, a threaded connection. Specifically, the second abutment 144 is provided with a threaded hole, and the first end 121 and the base are also provided with corresponding threaded holes. The threaded fastener can be inserted into the threaded hole and tightened, thereby fixing the auxiliary component 140.

[0081] Specifically, the second abutment 144 forms a stable contact surface between the auxiliary component 140 and the first end 121, preventing the auxiliary component 140 from loosening or shifting due to vibration or other external forces. Furthermore, the second abutment 144 also acts as a limiter, ensuring that the auxiliary component 140 does not shift due to vibration or other external forces when in the first installation position 141. In this way, the indoor unit 100 not only achieves efficient and convenient maintenance operations but also ensures the reliability and safety of the equipment during daily operation.

[0082] It is understood that in some embodiments, the second abutment 144 can employ various structures to achieve its function. For example, the second abutment 144 can be designed with an elastic pad, which allows the user to increase the contact area and friction between the second abutment 144 and the first end 121, ensuring the stable installation of the auxiliary component 140. The elastic pad design not only provides a better sealing effect but also reduces vibration and noise, improving the user experience.

[0083] In some embodiments, the first end 121 includes a first abutment 1212, and the auxiliary component 140 includes a second abutment 144. The first abutment 1212 and the second abutment 144 work together to ensure the stability and reliability of the auxiliary component 140 in the first installation position 141, preventing it from loosening or shifting, thereby improving the operational stability and maintenance convenience of the indoor unit 100. These designs not only extend the service life of the equipment but also provide users with a safer and more reliable user experience.

[0084] In some embodiments, the heat exchanger 120 is configured to be detached from the chassis 111 along a first direction X, with a second direction Y perpendicular to the first direction X. The auxiliary component 140 has a first connecting structure 145, and the chassis 111 has a second connecting structure 1112. When the auxiliary component 140 is in a second mounting position 142, the first connecting structure 145 is connected to the second connecting structure 1112 to limit relative sliding between the auxiliary component 140 and the chassis 111 along the second direction Y.

[0085] This design ensures that during the process of the auxiliary component 140 switching to the second mounting position 142 to support the first end 121 and increasing the size of the first opening 122, the auxiliary component 140 will not be displaced along the second direction Y due to external forces or vibrations, thus guaranteeing its stability and reliability. In this way, users can easily disassemble the impeller 130 and the heat exchanger 120 without damaging the equipment structure, improving equipment maintenance efficiency and user experience.

[0086] It is understood that in some embodiments, the first connecting structure 145 and the second connecting structure 1112 can achieve their functions in various ways. For example, the first connecting structure 145 can be designed with a snap-fit ​​structure, allowing the user to easily secure the auxiliary component 140 to the chassis 111 using a simple snap-fit ​​operation. The snap-fit ​​design is not only easy to operate but also offers high stability and reliability. To further improve the user experience, in some embodiments, the snap-fit ​​can be designed with a spring, allowing the user to quickly unlock the auxiliary component 140 by pressing or pulling the snap-fit, achieving rapid disassembly.

[0087] Furthermore, the first connecting structure 145 and the second connecting structure 1112 can also be designed to accommodate multiple installation methods. For example, the first connecting structure 145 and the second connecting structure 1112 can be equipped with multiple different types of mounting holes or mounting posts, allowing users to choose the appropriate installation method according to their actual needs. This multi-functional design not only improves the compatibility of the equipment but also provides users with more choices, meeting different installation requirements.

[0088] The design of the first connecting structure 145 of the auxiliary component 140 and the second connecting structure 1112 of the chassis 111 is based on the consideration of preventing relative sliding of the auxiliary component 140 along the second direction Y when in the second installation position 142. Specifically, when the auxiliary component 140 is in the second installation position 142, the first connecting structure 145 is connected to the second connecting structure 1112, forming a stable locking mechanism. This not only improves the stability of the auxiliary component 140 when supporting the first end 121, but also ensures its safety during use. In this way, the indoor unit 100 not only achieves efficient and convenient maintenance operations, but also ensures the reliability and safety of the equipment in daily operation. This design greatly simplifies the disassembly process of the impeller 130 and the heat exchanger 120, improves maintenance efficiency, and also reduces maintenance costs and technical difficulty, thereby enhancing the user experience.

[0089] Referring to Figures 4 to 7, in some embodiments, the first connecting structure 145 includes a first slot 1451, and the second connecting structure 1112 includes a first protrusion 1113. When the auxiliary component 140 is in the second mounting position 142, the first protrusion 1113 is at least partially engaged with the first slot 1451 along the second direction Y. This design ensures that the auxiliary component 140 is securely fixed to the chassis 111 after switching to the second mounting position 142, preventing it from sliding along the second direction Y, thereby guaranteeing its stability and reliability.

[0090] Specifically, the engagement of the first slot 1451 and the first protrusion 1113 provides a reliable locking point, ensuring that the auxiliary component 140 will not shift due to external force or vibration when supporting the first end 121. In this way, users can easily disassemble the impeller 130 and the heat exchanger 120 without damaging the equipment structure, improving equipment maintenance efficiency and user experience.

[0091] In another embodiment, the first slot 1451 and the first protrusion 1113 can be designed with a guiding function. For example, the first slot 1451 can be provided with a guide rail or guide groove, allowing the user to accurately install the auxiliary component 140 into the second installation position 142. This guiding design not only improves installation accuracy but also simplifies the user's operation steps and increases work efficiency. To further improve the portability and ease of use of the device, the first slot 1451 and the first protrusion 1113 can also be designed as an adjustable structure, allowing for easy adjustment to accommodate auxiliary components 140 of different sizes, further improving the device's compatibility and flexibility.

[0092] Furthermore, the first slot 1451 and the first protrusion 1113 can also be designed with a multi-locking function. For example, the first slot 1451 can be provided with multiple locking positions, and the user can select different locking positions for locking according to actual needs. This multi-locking design not only improves the installation accuracy of the auxiliary component 140, but also ensures its stability during use, thereby improving the operational reliability of the entire device.

[0093] The design of the first slot 1451 and the first protrusion 1113 is intended to ensure the stability and reliability of the auxiliary component 140 in the second mounting position 142. By having the first protrusion 1113 engage with the first slot 1451 along the second direction Y, movement of the auxiliary component 140 due to external vibration or other factors can be effectively prevented. This not only improves the installation accuracy of the auxiliary component 140 but also ensures its stability during use, thereby enhancing the overall operational reliability of the equipment.

[0094] Referring to Figures 4 to 7, in some embodiments, the first connecting structure 145 includes a second protrusion 1452 and a third protrusion 1453 spaced apart from each other, and the gap between the second protrusion 1452 and the third protrusion 1453 forms a first slot 1451. When the auxiliary member 140 is in the second mounting position 142, the first protrusion 1113 on the chassis 111 is at least partially engaged in the first slot 1451 along the second direction Y. This ensures that the auxiliary member 140 will not slide along the second direction Y due to external force or vibration during the process of switching to the second mounting position 142 to support the first end 121 and increase the size of the first opening 122, thereby ensuring its stability and reliability.

[0095] Furthermore, when the auxiliary component 140 is in the first mounting position 141, it is connected to the chassis 111 and at least partially covers the first opening 122. The auxiliary component 140 also includes a second abutment 144, which, when the auxiliary component 140 is in the first mounting position 141, extends away from the receiving space 112 to the side of the first end 121 facing away from the receiving space 112, and the end of the second abutment 144 facing away from the auxiliary component 140 abuts against the side wall of the first end 121 facing away from the receiving space 112. This design not only improves the stability of the auxiliary component 140 in the first mounting position 141 but also prevents external foreign objects from entering the receiving space 112, protecting the safe operation of internal components.

[0096] In some embodiments, at least one of the second protrusion 1452 and the third protrusion 1453 serves as the second abutment 144. Thus, the second protrusion 1452 or the third protrusion 1453 of the auxiliary component 140 can be reused in a time-sharing manner (when the auxiliary component 140 is in the first mounting position 141, the second protrusion 1452 or the third protrusion 1453 can enhance the connection reliability between the auxiliary component 140 and the heat exchanger 120. When the auxiliary component 140 is in the second mounting position 142, the second protrusion 1452 and the third protrusion 1453 can work together and cooperate with the first protrusion 1113 to achieve stable support of the auxiliary component 140 for the first end 121), effectively reducing the design difficulty of the auxiliary component 140 and further enhancing its stability in the first mounting position 141. In this way, users can easily disassemble the impeller 130 and the heat exchanger 120 without damaging the equipment structure, improving equipment maintenance efficiency and user experience.

[0097] The second protrusion 1452 and the third protrusion 1453 are designed to enhance the stability and reliability of the auxiliary component 140 in the first mounting position 141 and the second mounting position 142. Specifically:

[0098] The engagement of the first slot 1451 and the first protrusion 1113: When the auxiliary component 140 is in the second mounting position 142, the first protrusion 1113 is engaged along the second direction Y in the gap formed by the second protrusion 1452 and the third protrusion 1453. This not only restricts the sliding of the auxiliary component 140 along the second direction Y, but also ensures its stability when supporting the first end 121. This design greatly simplifies the disassembly process of the impeller 130 and the heat exchanger 120, improves maintenance efficiency, reduces maintenance costs and technical difficulty, and enhances the user experience.

[0099] The function of the second abutment 144 is as follows: When the auxiliary member 140 is in the first mounting position 141, the second abutment 144 extends away from the receiving space 112 and abuts against the side wall of the first end 121 facing away from the receiving space 112. This not only improves the stability of the auxiliary member 140 in the first mounting position 141, but also prevents external foreign objects from entering the receiving space 112, protecting the safe operation of the internal components. At the same time, the second protrusion 1452 or the third protrusion 1453, as part of the second abutment 144, further enhances the stability of the auxiliary member 140 in the first mounting position 141.

[0100] The second protrusion 1452, the third protrusion 1453, and the second abutment 144 work together to ensure the stability and reliability of the auxiliary component 140 in the first installation position 141 and the second installation position 142, preventing relative sliding along the second direction Y, thereby improving the operational stability and maintenance convenience of the indoor unit 100. These designs not only extend the service life of the equipment but also provide users with a safer and more reliable user experience.

[0101] Referring to Figures 4 to 7, in some embodiments, the chassis 111 includes a front edge 1114 located on the front side and a side edge 1115 located on the side of the front edge 1114 near the first end 121. The second connecting structure 1112 includes the front edge 1114 and the side edge 1115. Specifically, the first connecting structure 145 also includes a first slot 1451 and a second slot 1454. When the auxiliary member 140 is in the second mounting position 142, the front edge 1114 is engaged in the first slot 1451, and the side edge 1115 is engaged in the second slot 1454. This design ensures that the auxiliary member 140 will not slide due to external force or vibration during the process of switching to the second mounting position 142 to support the first end 121 and increase the size of the first opening 122, further ensuring its stability and reliability.

[0102] Specifically, the design of the front edge 1114 and the side edge 1115 not only enhances the connection strength between the auxiliary component 140 and the chassis 111, but also provides better positioning accuracy, ensuring the stability of the auxiliary component 140 in the second mounting position 142.

[0103] It is understood that in some embodiments, the first slot 1451 and the second slot 1454 can employ various structures to achieve their functions. For example, the first slot 1451 and the second slot 1454 can be designed with a structure made of elastic material. The user can use the elastic material to increase the friction between the front edge 1114 and the side edge 1115 and the slot, ensuring the stable installation of the auxiliary component 140. Simultaneously, it can also protect the auxiliary component 140, preventing indentations or scratches from appearing on its surface, thereby improving its aesthetics.

[0104] Furthermore, the front edge 1114 and side edge 1115 can also be designed with multiple locking functions. For example, the front edge 1114 and side edge 1115 can be provided with multiple locking positions, allowing users to select different locking positions for locking according to actual needs. This not only improves the installation accuracy of the auxiliary component 140 but also ensures its stability during use, thereby enhancing the overall operational reliability of the device.

[0105] The design of the front edge 1114 and side edge 1115 enhances the stability and reliability of the auxiliary component 140 in the second mounting position 142. Specifically:

[0106] The engagement of the slots and edges: When the auxiliary component 140 is in the second mounting position 142, the front edge 1114 is engaged in the first slot 1451, and the side edge 1115 is engaged in the second slot 1454. This not only restricts the sliding of the auxiliary component 140 along the second direction Y, but also ensures its stability when supporting the first end 121. This design greatly simplifies the disassembly process of the impeller 130 and the heat exchanger 120, improves maintenance efficiency, reduces maintenance costs and technical difficulty, and enhances the user experience.

[0107] Enhanced connection strength: The design of the front edge 1114 and side edge 1115 not only enhances the connection strength between the auxiliary component 140 and the chassis 111, but also provides better positioning accuracy, ensuring the stability of the auxiliary component 140 in the second installation position 142. In this way, the indoor unit 100 not only achieves efficient and convenient maintenance operations, but also ensures the reliability and safety of the equipment in daily operation.

[0108] In some embodiments, when the first end 121 is connected to the chassis 111, the size of the first opening 122 is smaller than the minimum detachment size of the impeller 130; while when the first end 121 is at least partially detached from the chassis 111 and the auxiliary component 140 is located in the second mounting position 142, the size of the first opening 122 is larger than the minimum detachment size of the impeller 130. This design allows users to easily disassemble the impeller 130 without damaging the equipment structure, improving equipment maintenance efficiency and user experience. It should be noted that a plane perpendicular to the axis of the first opening 122 is defined as the projection plane. If the projection formed by the first opening 122 on the projection plane cannot completely cover the projection formed by the impeller 130 at any position on the projection plane, then the size of the first opening 122 is considered smaller than the minimum detachment size of the impeller 130. Similarly, if the projection formed by the first opening 122 on the projection plane can at least completely cover the projection formed by the impeller 130 at any position on the projection plane, then the size of the first opening 122 is considered larger than the minimum detachment size of the impeller 130.

[0109] Specifically, when the first end 121 is fully mounted on the chassis 111, the size of the first opening 122 is small, insufficient to allow the impeller 130 to detach from it. This ensures the sealing and safety of the equipment during normal operation, preventing foreign objects from entering the receiving space 112. However, when the user needs to disassemble the impeller 130, only the first end 121 needs to be partially disassembled, and the auxiliary component 140 is switched to the second mounting position 142. At this time, the size of the first opening 122 increases, sufficient to allow the impeller 130 to detach smoothly from it. This not only simplifies the disassembly process of the impeller 130 but also avoids equipment damage caused by forced disassembly, ensuring the safety and reliability of the equipment.

[0110] It is understood that, in some embodiments, the size variation of the first opening 122 can be achieved in various ways. For example, the auxiliary component 140 can be designed as a component with a telescopic structure, allowing the user to adjust the telescopic structure to change the size of the first opening 122. The telescopic structure design not only provides greater flexibility but also allows for precise control of the size of the first opening 122 according to actual needs, ensuring that the impeller 130 can be easily disassembled.

[0111] In another embodiment, the first end 121 can be designed as a component with a hinge structure. For example, the first end 121 can rotate around the hinge. When the user needs to disassemble the impeller 130, the first end 121 can be rotated by a certain angle, and the auxiliary component 140 is placed between the first end 121 and the base, thereby increasing the size of the first opening 122. This hinge design is not only easy to operate, but also has high stability and reliability. To further improve maintenance convenience, the hinge can be designed with a locking mechanism, which allows maintenance personnel to fix the position of the first end 121 and prevent it from moving accidentally during disassembly.

[0112] Furthermore, the auxiliary component 140 can also be designed with an automatic adjustment function. For example, the auxiliary component 140 can be equipped with sensors and actuators. When it is detected that the first end 121 has been partially disassembled, the actuators will automatically adjust the position of the auxiliary component 140 to increase the size of the first opening 122. This automated design not only improves disassembly efficiency but also reduces the number of steps required by the user, thus enhancing the user experience.

[0113] A second aspect of this application also provides an air conditioner 10, which includes an outdoor unit and an indoor unit 100 as described in any of the above embodiments and implementations. The indoor unit 100 and the outdoor unit are connected by connecting pipes, wires, and other components to form a complete air conditioning system. Specifically, the indoor unit 100 is responsible for air handling and heat exchange, while the outdoor unit contains the main refrigeration components such as a compressor and condenser. The separate design between the indoor and outdoor units also helps to reduce noise and improve the user experience.

[0114] Please refer to Figure 12. A third aspect of this application also provides a maintenance method applicable to the maintenance of the indoor unit 100 described in any of the above embodiments and implementation methods. The maintenance method includes:

[0115] S101: Disassembling the first end 121; First, the user needs to partially disassemble the first end 121 of the heat exchanger 120, at least partially detaching it from the chassis 111. This operation prepares for subsequently increasing the size of the first opening 122 so that the impeller 130 can be easily disassembled.

[0116] S102: Remove the auxiliary component 140 located at the first mounting position 141; then, the user removes the auxiliary component 140 that was originally located at the first mounting position 141. At this time, the auxiliary component 140 no longer covers the first opening 122, providing space for subsequent operations.

[0117] S103: Install the auxiliary component 140 at the second mounting position 142; then, the user reinstalls the auxiliary component 140 to the second mounting position 142, i.e., between the first end 121 and the chassis 111. At this time, the auxiliary component 140 provides support, ensuring the stability of the first end 121 and increasing the size of the first opening 122.

[0118] S104: Disassemble the impeller 130; Finally, the user can disassemble the impeller 130 from the enlarged first opening 122 to complete the disassembly of the impeller 130. Throughout the process, the presence of the auxiliary component 140 avoids problems such as structural instability and operational difficulty caused by directly disassembling the first end 121.

[0119] In some embodiments, the auxiliary component 140 located at the first mounting position 141 may be removed before the first end 121 is removed.

[0120] It should be noted that if the embodiments of this application involve directional indications (such as up, down, left, right, front, back, etc.), these directional indications are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. When a direction reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, it can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the direction reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0121] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions.
