[0060] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0061] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0062] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0063] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0064] With economic development, people's pursuit of quality of life in travel and tourism is increasing, and RVs are gradually becoming a permanent place of residence for residents' travel. As a result, people have put forward higher environmental requirements for RVs, and RV air conditioners have emerged. As the main electrical equipment for improving the internal environment of RVs, RV air conditioners are gradually becoming standard equipment in modern RVs.

[0065] RV air conditioners are generally installed on the roof of the vehicle, so they are classified as roof-mounted air conditioners. Roof-mounted air conditioners typically include an indoor air duct assembly and an outdoor air duct assembly. The indoor air duct assembly is used to exchange heat with the interior of the RV before discharging air, while the outdoor air duct assembly is used to exchange heat with the outside before discharging air. However, in traditional roof-mounted air conditioners, the indoor and outdoor air duct assemblies are assembled as two separate systems inside the unit, resulting in poor overall compactness and limited assembly space. Furthermore, the installation and control of the indoor and outdoor air duct assemblies are not flexible.

[0066] More specifically, in related technologies, one type of air conditioner uses two motors to drive the impellers corresponding to two different air ducts. Specifically, an axial fan can be used to dissipate airflow for condenser cooling, while a centrifugal fan provides the circulation power for the indoor and outdoor air ducts. Because of this, the two fans can only be assembled using different motor brackets, resulting in a fixed air duct system. Another type of air conditioner uses a single motor to simultaneously drive the impellers corresponding to both the front and rear air ducts. In this case, the motor bracket is directly associated with the motor, and cannot be replaced with a multi-fan layout. Therefore, the air duct layout of air conditioners in these related technologies can only correspond to one assembly and control method, and cannot be flexibly changed. Furthermore, assembling different fans separately requires different motor brackets, which occupies a significant amount of internal space in the air conditioner, hindering a compact layout.

[0067] Based on this, this application provides a motor mounting bracket 200, including a first connecting structure and a second connecting structure. Along a first direction, the second connecting structure is spaced apart from the first connecting structure. At least one of the first and second connecting structures is adapted to connect a motor. It is understood that the first and second connecting structures allow the motor mounting bracket 200 to change the motor mounting configuration according to different needs. Specifically, in one application scenario, the motor mounting bracket 200 can mount one motor, and thus, the motor can be connected to one of the first and second connecting structures, or the motor can be adapted to connect to both the first and second connecting structures simultaneously. In another application scenario, the motor mounting bracket 200 can mount two motors, and thus, one motor can be connected to one of the first and second connecting structures, and the other motor can be connected to the other of the first and second connecting structures. Depending on the requirements, the structural forms of the first and second connecting structures can be determined, and both can be adapted to mount the same type of motor or different types of motors. For example, in some embodiments, the motor mounting bracket 200 can be used in the air conditioner 10, and when the motor mounting bracket 200 is equipped with two motors, one of the motors can be used as an indoor fan connected to the indoor air duct 140, and the other can be used as an outdoor fan connected to the outdoor air duct 160.

[0068] For the specific form of motor mounting bracket 200 connecting the motor, please refer to... Figure 6 and Figure 7 The first connecting structure includes a first support surface 220 for connecting the motor and a first through hole through which the motor output shaft passes. The second connecting structure includes a second support surface 230 for connecting the motor and a second through hole through which the motor output shaft passes. A connecting side plate 240 is connected between the first support surface 220 and the second support surface 230 along a first direction and together defines the motor receiving cavity 210. It can be understood that when the motor mounting bracket 200 is used to install one motor, the first support surface 220 (or the second support surface 230) can position and fix the end face of the main body of the motor, and the first through hole and the second through hole are connected so that the motor output shaft can pass through the first through hole and the second through hole; when the motor mounting bracket 200 is used to install two motors, the first support surface 220 and the second support surface 230 can respectively position and fix the end faces of the main bodies of the two motors, and the motor output shafts of the two motors can respectively pass through the first through hole and the second through hole.

[0069] This application also provides a motor assembly including a motor mounting bracket 200 of any of the above embodiments and at least one motor. The motor is mounted in a motor receiving cavity 210 of the motor mounting bracket 200; in a first direction, at least one motor is connected to at least one of a first support surface 220 and a second support surface 230, and the drive shaft of at least one motor passes through at least one of a first through hole and a second through hole. The above description indicates that the motor assembly is adapted to connect at least one motor to the motor mounting bracket 200 in different ways.

[0070] Under different connection methods, the aforementioned motors may include a first motor 310, a second motor 340, and a third motor 400. For different connection methods of the motor assembly connecting the motors, the motor assembly correspondingly has a first installation state and a second installation state. In the first installation state, the first support surface 220 of the motor mounting bracket 200 is connected to the first motor 310, and the second support surface 230 is connected to the second motor 340 of the air conditioner 10. The output shaft of the first motor 310 passes through a first through hole, and the output shaft of the second motor 340 passes through a second through hole. In the second installation state, the first support surface 220 and / or the second support surface 230 of the motor mounting bracket 200 are connected to the third motor 400. At least a portion of the third motor 400 is disposed within the motor receiving cavity 210, and the output shaft of the third motor 400 passes through the first and second through holes. For the limitations of the above connection methods and related configurations, please refer to the relevant descriptions of the motor mounting bracket 200 in the above embodiments; they will not be repeated here.

[0071] This application also provides an air conditioner that includes the motor assembly of any of the above embodiments. The air conditioner 10 may be a top-mounted air conditioner as described above or an air conditioner of other assembly types and locations. The specific purpose and installation method are not limited here.

[0072] Specifically, see Figures 1 to 3 The air conditioner 10 includes a housing assembly 100, a motor mounting bracket 200, a first impeller 320, and a second impeller 350. The housing assembly 100 defines an indoor air duct 140 and an indoor air inlet 111 and an indoor air outlet 112 communicating with the indoor air duct 140. It also defines an outdoor air duct 160 and an indoor air inlet 111 communicating with the indoor air duct 140. The first impeller 320 is disposed in the indoor air duct 140. The housing assembly 100 also defines an outdoor air duct 160 and an outdoor air inlet 121 and an outdoor air outlet 122 communicating with the outdoor air duct 160. The second impeller 350 is disposed in the outdoor air duct 160. The motor mounting bracket 200 is disposed in the housing assembly 100 and includes a first connecting structure and a second connecting structure.

[0073] The motor assembly has a first mounting state and a second mounting state, see below. Figure 4 and Figure 6 When the motor mounting bracket 200 is in the first installation state, the motor assembly includes a first motor 310 and a second motor 340. A first connecting structure connects the first motor 310, and a second connecting structure connects the second motor 340. The output shaft of the first motor 310 extends into the indoor air duct 140 and connects to the first impeller 320, while the output shaft of the second motor 340 extends into the outdoor air duct 160 and connects to the second impeller 350. This configuration allows the first motor 310 and the second motor 340 to function as an indoor fan connected to the indoor air duct 140.

[0074] See Figure 5 and Figure 7 When the motor assembly is in the second installation state, the motor assembly includes a third motor 400. At least one of the first and second connecting structures is connected to the third motor 400. The first shaft 410 of the third motor 400 extends into the indoor air duct 140 and is connected to the first impeller 320, and the second shaft 420 extends into the outdoor air duct 160 and is connected to the second impeller 350. The third motor 400 can be a motor with two output shafts on both sides. The first shaft 410 is connected to the centrifugal impeller to drive the impeller of the indoor air duct 140 to circulate air, and the second shaft 420 extends into and is connected to the axial fan blades to drive the fan blades of the outdoor air duct 160 to circulate outdoor heat exchange airflow. Based on the above description of the first installation state, the motor assembly is configured to optionally form either the first installation state or the second installation state.

[0075] See Figures 8 to 9 Generally, the air conditioner 10 also includes an indoor heat exchanger 330. Both the first impeller 320 and the indoor heat exchanger 330 are located within the indoor air duct 140. The indoor air inlet 111 draws air into the indoor air duct 140, and after exchanging heat with the indoor heat exchanger 330 within the indoor air duct 140, the air is discharged from the indoor air outlet 112 by the rotation of the first impeller 320. Similarly, the air conditioner 10 also includes an outdoor heat exchanger 360. The outdoor heat exchanger 360 and the second impeller 350 are located within the outdoor air duct 160. The outdoor air inlet 121 draws air into the outdoor air duct 160, and after exchanging heat with the outdoor heat exchanger 360 within the outdoor air duct 160, the air is discharged from the outdoor air outlet 122 by the rotation of the second impeller 350.

[0076] The rotation of the first impeller 320 and the second impeller 350 requires motor control. The first and second installation states described above are then applied to the configuration of the first impeller 320 and the second impeller 350. In some embodiments, see [reference needed]. Figure 4 and Figure 6The motor assembly is in a first installation state. In the first installation state, the first impeller 320 is driven by the first motor 310 and the second impeller 350 is driven by the second motor 340. At this time, the first motor 310 that drives the first impeller 320 to rotate and the second motor 340 that drives the second impeller 350 to rotate are assembled in the same structure, namely the motor fixing bracket 200. There is no need to set up and arrange the fixing structure of the first motor 310 and the second motor 340 separately, thereby achieving a compact assembly of the first motor 310 and the second motor 340.

[0077] In other embodiments, see Figure 5 and Figure 7 The motor assembly forms a second installation state. In the second installation state, the third motor 400 is not only the power source for the first impeller 320, but also the power source for the second impeller 350. That is, the first impeller 320 and the second impeller 350 are mounted on the same third motor 400. The opposite sides of the third motor 400 form a first shaft 410 and a second shaft 420. The first shaft 410 extends into the indoor air duct 140, and the second shaft 420 extends into the outdoor air duct 160. The first impeller 320 is mounted on the first shaft 410, and the second impeller 350 is mounted on the second shaft 420, thus forming a single motor dual-shaft structure.

[0078] During assembly, the operator can choose to assemble either the third motor 400 or the first motor 310 and the second motor 340 on the motor mounting bracket 200, depending on the requirements. This allows for the selection of either the second or first installation state of the motor assembly. The first installation state is formed by using the first motor 310 and the second motor 340 to fix the motor mounting bracket 200, while the second installation state is formed by using the third motor 400 to fix the motor mounting bracket 200. This allows the air conditioner 10 to form a duct layout structure that can switch between single-motor and dual-motor configurations.

[0079] The motor mounting bracket 200 can simultaneously control the motors of both the indoor air duct 140 and the outdoor air duct 160, achieving a compact internal structure for the air conditioner 10. Specifically, in the first installation state of the motor assembly, by mounting the first motor 310 and the second motor 340 on the same motor mounting bracket 200, a compact layout is achieved, enabling independent operation and control of both front and rear motors and dual air ducts, resulting in a more rational air duct layout and structure. In the second installation state of the motor mounting bracket 200, a single motor can simultaneously drive the first impeller 320 of the indoor air duct 140 and the second impeller 350 of the outdoor air outlet duct. By changing the installation state of the motor assembly and switching the motor settings, versatility is improved and production costs are reduced.

[0080] In one embodiment, the motor mounting bracket 200 forms a first connection structure and a second connection structure at opposite ends, respectively. That is, the first motor 310 and the second motor 340 are fixed at opposite ends of the motor mounting bracket 200 and respectively cooperate with the first impeller 320 in the first air duct and the second impeller 350 in the second air duct. In this way, the output shafts of the first motor 310 and the second motor 340 can be assembled at the same height, and the first impeller 320 and the second impeller 350 can rotate coaxially. This allows the first motor 310 and the second motor 340 to maintain relative matching when the air conditioner 10 is running, avoiding unstable vertical jumping of the whole unit due to assembly problems, and improving the overall stability and reliability of the air conditioner 10.

[0081] In one embodiment, see [reference] Figures 8 to 11 The housing assembly 100 includes an inner air duct component 130 and an outer air duct component 150. The inner air duct component 130 defines an indoor air duct 140, and the outer air duct component 150 defines an outdoor air outlet duct. An outdoor air inlet duct is formed between the inner air duct component 130 and the outer air duct component 150. The outdoor air inlet duct and the outdoor air outlet duct are connected to form an outdoor air duct 160. The motor mounting bracket 200 is disposed in the outdoor air inlet duct.

[0082] The first impeller 320 and the indoor heat exchanger 330 are installed in the indoor air duct 140. When the first motor 310 is running, indoor air enters the indoor air duct 140 through the indoor air inlet 111 and flows along the indoor air duct 140, so that the indoor air exchanges heat with the indoor heat exchanger 330 and then flows out from the indoor air outlet 112. Similarly, the second impeller 350 and the outdoor heat exchanger 360 are installed in the outdoor air outlet duct. When the second motor 340 is running, outdoor air enters the outdoor air inlet 121 and then enters the outdoor air outlet duct, finally exchanging heat with the outdoor heat exchanger 360 in the outdoor air outlet duct and then flowing out from the outdoor air outlet 122. Alternatively, when the third motor 400 is running, it drives the first impeller 320 and the second impeller 350 to rotate simultaneously, thus achieving both indoor and outdoor heat exchange at the same time.

[0083] In one embodiment, see [reference] Figures 6 to 7 The motor mounting bracket 200 has a first support surface 220 and a second support surface 230 that are arranged opposite to each other and spaced apart. The first support surface 220 forms a first connection structure and the second support surface 230 forms a second connection structure. In other words, the first motor 310 is connected to the first support surface 220, the second motor 340 is connected to the second support surface 230, and the third motor 400 is connected to either the first support surface 220 or the second support surface 230.

[0084] Specifically, the first support surface 220 has a first through hole, and the second support surface 230 has a second through hole. The first through hole faces the indoor air duct 140, and the second through hole faces the outdoor air outlet duct. The first motor 310 is connected to the first support surface 220, and the second motor 340 is connected to the second support surface 230. The first motor 310 and the second motor 340 are spaced apart along the direction from the first through hole to the second through hole. The output shaft of the first motor 310 passes through the first through hole and enters the indoor air duct 140, and the output shaft of the second motor 340 passes through the second through hole and enters the outdoor air outlet duct, thereby realizing the assembly.

[0085] Alternatively, the third motor 400 is connected to the second support surface 230, and the first shaft 410 extends into the indoor air duct 140 through the first perforation, and the second shaft 420 extends into the outdoor air outlet duct, thereby achieving assembly.

[0086] To facilitate switching the installation status of the motor components, the assembly method of the first motor 310, the second motor 340, and the third motor 400 can be set to detachable installation. For example, connection holes can be made on both the first support surface 220 and the second support surface 230, and different motors can be installed by conventional connection methods such as bolts.

[0087] In some embodiments, the first support surface 220 and the second support surface 230 can be separately connected and fixed to the housing assembly 100. In this case, the first support surface 220 and the second support surface 230 can be connected by an additional structure, or they can be not connected. To further improve the fixing strength of the motor mounting bracket 200, a motor receiving cavity 210 is formed between the first support surface 220 and the second support surface 230. Specifically, refer to... Figures 6 to 7 The connecting side plate is connected between the first support surface 220 and the second support surface 230 along the first direction and together defines the motor receiving cavity 210. The first support surface 220 has a first through hole and the second support surface 230 has a second through hole. The first through hole faces the indoor air duct 140 and the second through hole faces the outdoor air outlet duct. The motor receiving cavity 210 communicates with the first through hole and the second through hole.

[0088] At this time, the functions of the first and second through holes are, on the one hand, to facilitate the installation of the motor into the motor receiving cavity 210. For example, when the motor assembly is in the first installation state, the output shaft of the first motor 310 passes through the first through hole and is placed in the motor receiving cavity 210, and the output shaft of the second motor 340 passes through the second through hole and is placed in the motor receiving cavity 210. On the other hand, it is also to facilitate the output shaft of the motor to pass out after the motor is installed into the motor receiving cavity 210. For example, when the motor assembly is in the second installation state, the first and second through holes can allow the output shaft of the third motor 400 to pass through.

[0089] The first support surface 220 and the second support surface 230 respectively support the first motor 310 and the second motor 340. When the motor assembly is in the first installation state, the first motor 310 is partially disposed in the motor receiving cavity 210 and connected to the first support surface 220. Specifically, during installation, a portion of the first motor 310 can be inserted into the motor receiving cavity 210 through the first through hole and then connected to the first support surface 220. The second motor 340 is partially disposed in the motor receiving cavity 210 and connected to the second support surface 230. Specifically, during installation, a portion of the second motor 340 can be inserted into the motor receiving cavity 210 through the second through hole and then connected to the second support surface 230. The first motor 310 and the second motor 340 are spaced apart along the direction from the first through hole to the second through hole, so that the motor fixing bracket 200 provides separate support for the first motor 310 and the second motor 340, and the first motor 310 and the second motor 340 are fixed separately and do not interfere with each other.

[0090] When the motor assembly is in the second installation state, the third motor 400 is partially disposed in the motor receiving cavity 210 and connected to the second support surface 230, and the first shaft 410 extends into the indoor air duct 140 through the first through hole. Specifically, during installation, a portion of the third motor 400 can be inserted into the motor receiving cavity 210 through the second through hole and then connected to the second support surface 230. At this time, the first shaft 410 extends out from the first through hole, and the second shaft 420 is located outside the motor receiving cavity 210.

[0091] Understandably, the sizes of the first and second through holes need to be universally set, that is, the second through hole should be able to pass through not only the second shaft 420 of the third motor 400, but also the second motor 340. Similarly, the first through hole should be able to pass through not only the first shaft 410 of the third motor 400, but also the first motor 310.

[0092] The connecting side plates 240 may include multiple plates. For example, in one specific embodiment, the motor mounting bracket 200 includes four connecting side plates 240 connected end to end, and each connecting side plate 240 is connected between the first support surface 220 and the second support surface 230 to form a cuboid motor mounting bracket 200. One side plate 240 of the motor mounting bracket 200 is connected to the housing assembly 100 to fix the motor mounting bracket 200. In other embodiments, the connecting side plates 240 may include one or more other types, which is not limited herein.

[0093] In one embodiment, reference Figure 4 and Figure 5According to one embodiment of the present invention, the housing assembly 100 of the air conditioner 10 includes a chassis 110 and a top cover 120. The top cover 120 is connected to the chassis 110. The bottom of the chassis 110 is provided with an indoor air inlet 111 and an indoor air outlet 112. Air inlet grilles are provided on both sides of the chassis 110 and the top cover 120 to form an outdoor air inlet 121. An air outlet grille is provided on the rear side of the top cover 120 and the chassis 110 to form an outdoor air outlet 122. It can be understood that, taking a motorhome as an example, the air conditioner 10 is installed on the top of the motorhome. The top of the motorhome has an installation opening (not shown in the attached drawings). The indoor air inlet 111 and the indoor air outlet 112 both face downward and are connected to the installation opening to realize indoor air circulation. The outside of the unit is air in from the side and air out to the rear to realize outdoor air flow.

[0094] It should be noted that the front-back, left-right, and up-down orientations described in the context of this utility model embodiment are all based on the chassis 110 and referenced by the orientation relationships marked in the figure. The front-back, left-right, and up-down orientations of the air conditioner 10 correspond one-to-one with the orientation of the RV.

[0095] Thus, the outdoor air outlet duct of this application directs airflow towards the rear of the unit, eliminating the problem of foreign objects falling into the outdoor air outlet duct and affecting the airflow. At the same time, it avoids the problem of poor heat exchange caused by the low air pressure against the wall during the high-speed movement of a vehicle, which compresses the outdoor air outlet 122 upwards. This improves the heat exchange efficiency.

[0096] In one embodiment, in conjunction with reference to Figures 8 to 9 The inner air duct component 130 is installed at the front of the chassis 110, and the outer air duct component 150 is installed at the rear of the chassis 110. A certain space is formed between the inner air duct component 130 and the outer air duct component 150. This space is the outdoor air intake duct. The outdoor air intake duct and the outdoor air outlet duct are connected to form a complete outdoor air duct 160. The outdoor air intake duct is connected to the outdoor air inlet 121, and the outdoor air outlet duct is connected to the outdoor air outlet 122. The air conditioner 10 draws air from the outer side of the unit into the outdoor air intake duct, and then exits from the rear through the outdoor air outlet duct. The motor mounting bracket 200 is fixed between the inner air duct component 130 and the outer air duct component 150, without occupying the space of the indoor air duct 140 and the outdoor air duct 160.

[0097] See Figures 10 to 12The air conditioner 10 also includes an electrical control box assembly 700 and a compressor 800. Both the electrical control box assembly 700 and the compressor are located within the outdoor air intake duct. Specifically, the electrical control box assembly 700, the motor mounting bracket 200, and the compressor 800 are arranged sequentially and at intervals along the left-right direction of the chassis 110. For example, the electrical control box assembly 700 is installed at the top of the outdoor air intake duct. The electrical control box assembly 700 is mounted between the inner air duct component 130 and the outer air duct component 150. The electrical control box assembly 700 is electrically connected to external electrical components via wiring. These external electrical components include the compressor 800, the first motor 310, the second motor 340, and other devices. The electrical control box assembly 700 is installed on the side closest to the chassis 110. The compressor 800 is installed in the space between the inner air duct component 130 and the outer air duct component 150, and is located on the side of the motor mounting bracket 200 away from the electrical control box assembly 700 in the left-right direction of the chassis 110. The compressor 800 is fixedly connected to the chassis 110.

[0098] It is understandable that the compressor 800 is surrounded by a piping structure, which connects the compressor 800 with the indoor heat exchanger 330 and the outdoor heat exchanger 360 to form a circulation loop, thereby forming the entire refrigeration system. In the refrigeration system, the indoor heat exchanger 330 is generally the evaporator and the outdoor heat exchanger 360 is the condenser.

[0099] In one embodiment, the inner air duct component 130 includes an inner air duct support 131 and an inner air duct cover 132. The inner air duct support 131 is disposed on the chassis 110, and the inner air duct cover 132 is closed on the inner air duct cover 132. The outer air duct component 150 includes an outer air duct support 151 and an outer air duct cover 152. The outer air duct support 151 is disposed on the chassis 110, and the outer air duct cover 152 is closed on the outer air duct support 151. The mounting base 114 is located between the inner air duct support 131 and the outer air duct support 151.

[0100] The indoor air duct 140 is defined by the inner air duct support 131 and the inner air duct cover 132, and the outdoor air outlet duct is defined by the outer air duct support 151 and the outer air duct cover 152. Both the indoor air duct 140 and the outdoor air duct 160 are formed by the upper and lower cover structures of the air duct support and the air duct cover, simplifying assembly line operations and improving assembly efficiency. Furthermore, it isolates the indoor air duct 140 from the outdoor air duct 160, preventing cross-contamination of indoor and outdoor air. Simultaneously, an installation space is formed between the inner air duct support 131 and the outer air duct support 151, which is partially formed by the outdoor air inlet duct. The mounting base 114 is placed within this installation space to securely mount the motor mounting bracket 200. Furthermore, in addition to the air duct being designed with upper and lower covers, the air duct electrical control components and the top cover housing can also be assembled with upper and lower covers, which further simplifies the assembly process and helps to maximize assembly efficiency.

[0101] Specifically, see Figure 4 and Figure 5 The chassis 110 includes a body 113 and a mounting base 114. The mounting base 114 protrudes from the body 113. The motor mounting bracket 200 is detachably mounted on the mounting base 114. Specifically, the mounting base 114 and the motor mounting bracket 200 may each have multiple mounting holes. The mounting base 114 and the motor mounting bracket 200 are fixedly connected by external bolts or other structures. The protrusion of the mounting base 114 raises the motor mounting bracket 200, thereby raising the first motor 310 and the second motor 340, or raising the third motor 400, to provide sufficient space for the rotation of the first impeller 320 and the second impeller 350.

[0102] In one embodiment, the inner air duct support 131 has a first opening 1311, and the outer air duct support 151 has a second opening 1511. The first opening 1311 connects the indoor air duct 140 to the outdoor air inlet duct, and the second opening 1511 connects the outdoor air inlet duct to the outdoor air outlet duct. The first opening 1311 serves only to connect the motor to the first impeller 320, while the second opening 1511 serves not only to connect the motor to the second impeller 350, but also to provide an airflow connection between the outdoor air inlet duct and the outdoor air outlet duct.

[0103] Specifically, when the motor assembly is in the first installation state, the output shaft of the first motor 310 passes through the first port 1311 to connect with the first impeller 320, and the output shaft of the second motor 340 passes through the second port 1511 to connect with the second impeller 350. When the motor assembly is in the second installation state, the first shaft 410 passes through the first port 1311 to connect with the first impeller 320, and the second shaft 420 passes through the second port 1511 to connect with the second impeller 350.

[0104] In some embodiments, the inner air duct component 130 may be made of insulating material, for example, the inner air duct support 131 and the inner air duct cover 132 may be made of foam material, which has an insulating effect. Similarly, the outer air duct component 150 may also be made of insulating material, which will not be described in detail here. The provision of the first passage 1311 and the second passage 1511 allows the inner air duct assembly and the outer air duct assembly to complete the assembly of the first impeller 320 and the second impeller 350 while installing the inner air duct support 131 and the outer air duct support 151, and then the inner air duct cover 132 and the outer air duct cover 152 are installed, thereby simplifying the assembly process.

[0105] In one embodiment, see [reference] Figure 4 , Figure 5 and Figure 11 The air conditioner 10 also includes a reinforcing plate 600, which is connected between the inner air duct cover 132 and the outer air duct cover 152, thereby enhancing the stability of the inner air duct component 130 and the outer air duct component 150 after installation. Specifically, the reinforcing plate 600 can be provided on the side of the motor mounting bracket 200 near the compressor 800 to better cope with the vibration of the compressor 800.

[0106] In one embodiment, the first impeller 320 is a centrifugal impeller, and the second impeller 350 is a cross-flow impeller. In the first installation state, the centrifugal impeller is located in the indoor air duct 140 and connected to the first motor 310, while the cross-flow impeller is located in the outdoor air outlet duct and connected to the second motor 340. In the second installation state, the centrifugal impeller is located in the indoor air duct 140 and connected to the first shaft 410, while the cross-flow impeller is located in the outdoor air outlet duct and connected to the second shaft 420.

[0107] For ease of explanation, the assembly process of the air conditioner 10 when the motor assembly is in the first mounting state and the second mounting state are described below:

At this time, the shaft of the first motor 310 extends into the inner air duct support 131, and the shaft of the second motor 340 extends into the outer air duct support 151. The centrifugal impeller is assembled on the first motor 310, and the first impeller 320 is assembled on the second motor 340.
