Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and in particular to an air conditioner. Background Technology

[0002] With increasing user demands, air conditioner fan components require cleaning and maintenance. In related technologies, the fan component is housed within a casing to drive airflow along the casing to the air outlet. When disassembling the fan component is necessary, the air conditioner's outer casing must first be opened, then the casing disassembled, and finally the fan component removed. After cleaning or maintenance, the fan component must be reassembled back into the casing, and then the entire unit reinstalled into the air conditioner's outer casing before being put back into use. However, this disassembly and assembly process is cumbersome, inefficient, and requires improvement. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0046] An air conditioner 100 according to an embodiment of the present invention includes an air conditioner body 1 and a fan component 2.

[0047] Combination Figure 1 and Figure 2 As shown, the air conditioner body 1 includes a housing 11 and a volute 12, with the volute 12 disposed inside the housing 11 and the fan assembly 2 disposed inside the housing 11. The housing 11 protects the volute 12 and the fan assembly 2, thereby improving the operational stability of the air conditioner 100.

[0048] like Figure 4 As shown, the fan component 2 includes a cross-flow impeller 21 and a motor assembly 22. The motor assembly 22 can drive the cross-flow impeller 21 to rotate, and the cross-flow impeller 21 can generate airflow and drive the airflow. The cross-flow impeller 21 is disposed inside the volute 12, which forms an airflow channel and can guide the flow path of the airflow. The airflow flows along the volute 12 under the drive of the cross-flow impeller 21.

[0049] The cross-flow fan 21 is disposed inside the volute 12. Optionally, the cross-flow fan 21 can be disposed upstream of the volute 12; the cross-flow fan 21 can also be disposed midway up the volute 12; and optionally, the cross-flow fan 21 can also be disposed downstream of the volute 12. The position of the cross-flow fan 21 is not limited here.

[0050] Combination Figure 5 and Figure 6 As shown, the motor assembly 22 is located outside the volute 12 and is connected to one axial end of the cross-flow fan 21. When the air conditioner 100 is running, the motor assembly 22 drives the cross-flow fan 21 to rotate to generate airflow. When the fan component 2 is disassembled or assembled, the motor assembly 22 is fixed to the cross-flow fan 21. When the motor assembly 22 is moved, it can drive the cross-flow fan 21 to move within the volute 12. The motor assembly 22 provides better grip on the cross-flow fan 21, which improves the ease of disassembly and assembly of the fan component 2. Furthermore, during the movement of the fan component 2, gripping the motor assembly 22 reduces the probability of damaging the blades of the cross-flow fan 21.

[0051] like Figure 2 As shown, the air conditioner body 1 has a disassembly port 13, which is located on the side of the air conditioner body 1 near the motor assembly 22. The disassembly port 13 allows the passage of the fan component 2, which moves axially along the cross-flow impeller 21. The fixed connection between the fan component 2 and the air conditioner body 1 can be released from the disassembly port 13, allowing the fan component 2 to be disassembled and reassembled from the disassembly port 13. More specifically, the fixed connection between the fan component 2 and the air conditioner body 1 can be released and restored from the disassembly port 13. When the fixed connection between the fan component 2 and the air conditioner body 1 is released, the fan component 2 can be pulled out or inserted through the disassembly port 13 by moving axially along the cross-flow impeller 21. For example, a maintenance worker can insert their hand or tools into the disassembly port 13 to reconnect the fixed connection between the fan component 2 and the air conditioner body 1, making the fan component 2 separable from the air conditioner body 1.

[0052] For example, when the disassembly port 13 is located on the side of the air conditioner body 1, the motor component 2 can be disassembled by side-pulling.

[0053] When the air conditioner 100 is running, the fan component 2 is fixedly connected to the air conditioner body 1 to ensure that the air conditioner 100 runs smoothly.

[0054] The fan component 2 and the air conditioner body 1 can be disassembled and assembled through the disassembly port 13. When it is necessary to remove the fan component 2, the fixed connection between the fan component 2 and the air conditioner body 1 can be released through the disassembly port 13, and then the fan component 2 can be pulled out from the disassembly port 13 along the axial direction of the cross-flow fan wheel 21; when it is necessary to assemble the fan component 2 to the air conditioner body 1, the fan component 2 is pushed in from the disassembly port 13 along the axial direction of the cross-flow fan wheel 21, and the fixed connection between the fan component 2 and the air conditioner body 1 is restored through the disassembly port 13, and the fan component 2 and the air conditioner body 1 can be assembled and fixed.

[0055] When the fan component 2 moves relative to the air conditioner body 1, the fan component 2 can pass through the disassembly port 13 of the air conditioner body 1, and the fan component 2 passes through the disassembly port 13 along the axial direction of the cross-flow fan 21. Since the motor assembly 22 is connected to one axial end of the cross-flow fan 21, the motor assembly 22 and the cross-flow fan 21 can pass through the disassembly port 13 along the axial direction of the cross-flow fan 21, which helps to avoid interference between the motor assembly 22 and the cross-flow fan 21 and improves assembly efficiency.

[0056] The disassembly port 13 is located on the side of the air conditioner body 1 near the motor assembly 22. When disassembling the fan assembly 2, the motor assembly 22 in the fan assembly 2 is removed from the air conditioner body 1 first, followed by the cross-flow fan wheel 21. When installing the fan assembly 2, the cross-flow fan wheel 21 in the fan assembly 2 enters the air conditioner body 1 first, followed by the motor assembly 22.

[0057] Unlike related technologies, the air conditioner 100 in this application embodiment allows for the assembly or disassembly of the fan component 2 and the air conditioner body 1 via the disassembly port 13 on the air conditioner body 1, without the need to disassemble the volute 12. This improves disassembly and assembly efficiency, enhances operational convenience, and makes the maintenance and cleaning of the air conditioner 100 simpler and more convenient. In related technologies, to disassemble the volute in the housing, the housing needs to be disassembled sufficiently to leave enough operating space for disassembling the volute. In this application embodiment, since the disassembly of the volute 12 is eliminated, the operating space for removing the fan component 2 can be reduced, thus reducing the disassembly and assembly steps of the housing 11.

[0058] According to the embodiment of the air conditioner 100 of the present invention, the fan component 2 can be independently disassembled and assembled from the disassembly port 13 on the air conditioner 100 body, eliminating the step of disassembling the volute 12 and reducing the disassembly and assembly steps of the casing 11, thereby improving disassembly and assembly efficiency, improving the convenience of operation, and making the maintenance and cleaning of the air conditioner 100 simpler and more convenient.

[0059] like Figure 2 , Figure 3 and Figure 14As shown, in some embodiments, the disassembly port 13 includes an external disassembly port 131 provided on the housing 11. The motor assembly 22 is provided corresponding to the external disassembly port 131. That is, when the external disassembly port 131 is opened, the motor assembly 22 inside the external disassembly port 131 can be observed along its through-path. On a projection plane perpendicular to the axial direction of the cross-flow fan 21, the projection of the motor assembly 22 is located within the projection of the external disassembly port 131. In other words, on a projection plane perpendicular to the axial direction of the cross-flow fan 21, the projection of the motor assembly 22 is located within the projection of the external disassembly port 131, and the projection of the cross-flow fan 21 is also located within the projection of the external disassembly port 131. Therefore, the cross-flow fan wheel 21 and motor assembly 22 of the fan component 2 are arranged along the axial direction of the cross-flow fan wheel 21, and can directly pass through the external disassembly port 131 along the axial direction of the cross-flow fan wheel 21 without adjusting the angle of the fan component 2 when passing through the external disassembly port 131. This helps to avoid interference between the fan component 2 and the air conditioner body 1 and improves the convenience of disassembly and assembly.

[0060] For example, the front of the housing 11 is provided with an air outlet 103, and the external disassembly port 131 is provided on the side of the housing 11. Normally, the side with the air outlet 103 faces the user (e.g., the front side). By placing the external disassembly port 131 and the air outlet 103 on different sides, the external disassembly port 131 can be located on a side not observed by the user (e.g., the left or right side). In this case, the motor component 2 can be disassembled and installed from the side. However, this application is not limited to this. In some other embodiments of this application, the external disassembly port 131 and the air outlet 103 can also be located on the same side.

[0061] For example, the disassembly / removal port 13 includes an outer disassembly / removal port 131 and an inner disassembly / removal port 132. The outer disassembly / removal port 131 is disposed on the housing 11, and the motor assembly 22 is disposed corresponding to the outer disassembly / removal port 131. The inner disassembly / removal port 132 is disposed on the volute housing 12 and covered by the motor assembly 22. On a projection plane perpendicular to the axis of the cross-flow fan 21, the projection of the motor assembly 22 is located within the projection of the outer disassembly / removal port 131, and the projection of the cross-flow fan 21 is located within the projection of both the inner disassembly / removal port 132 and the outer disassembly / removal port 131. When the motor assembly 22 is removed, the inner disassembly / removal port 132 is effectively opened, and the cross-flow fan 21 can pass through the inner disassembly / removal port 132. The size of the motor assembly 22 on the projection surface is smaller than the size of the external disassembly port 131 on the projection surface, so the motor assembly 22 can be removed through the external disassembly port 131. The size of the cross-flow fan 21 on the projection surface is smaller than the size of the internal disassembly port 132 and the external disassembly port 131 on the projection surface, so the cross-flow fan 21 can be removed along its axial direction through the internal disassembly port 132 and the external disassembly port 131.

[0062] In the above embodiment, the volute 12 is disposed inside the housing 11, and the inner disassembly port 132 is disposed inside the outer disassembly port 131. When the cross-flow fan 21 is removed from the air conditioner body 1, it first passes through the inner disassembly port 132 and then through the outer disassembly port 131. The motor assembly 22 is disposed corresponding to the outer disassembly port 131 and is disposed outside the volute 12. Therefore, the motor assembly 22 only passes through the outer disassembly port 131 and not through the inner disassembly port 132. During the disassembly and assembly of the fan component 2, the motor assembly 22 drives the cross-flow fan 21 to move. The motor assembly 22 is easier to hold and can be removed through the outer disassembly port 131. The cross-flow fan 21 can be removed through both the inner disassembly port 132 and the outer disassembly port 131. In summary, the cross-flow impeller 21 and motor assembly 22 of the fan component 2 are arranged along the axial direction of the cross-flow impeller 21, and can directly pass through the disassembly port 13 along the axial direction of the cross-flow impeller 21 without adjusting the angle of the fan component 2 when passing through the disassembly port 13. This helps to avoid interference between the fan component 2 and the air conditioner body 1 and improves the convenience of disassembly and assembly.

[0063] like Figures 1-3 As shown, in some embodiments, the air conditioner body 1 includes a service plate 14 for covering the external disassembly port 131, and the service plate 14 is movably connected to the housing 11. Optionally, the service plate 14 is detachably connected to the housing 11. The service plate 14 can cover the gap of the disassembly port 13, maintain the integrity of the appearance and protect the interior of the air conditioner 100, and improve the stability of operation.

[0064] In some embodiments, the motor assembly 22 and the volute 12 are fixedly connected by a first connector, which is provided corresponding to the external disassembly port 131 (i.e., when the external disassembly port 131 is opened, the first connector inside can be observed along the through direction of the external disassembly port 131), so that the first connector can be disassembled and assembled from the external disassembly port 131. The first connector can improve the reliability and stability of the fixed connection between the motor assembly 22 and the volute 12, thereby improving the operational stability of the air conditioner 100. In conjunction with the above embodiments, after disassembling the inspection plate 14, the external disassembly port 131 is opened, and the first connector can be disassembled and assembled through the external disassembly port 131. The motor assembly 22 can be pulled out or assembled into the air conditioner 100 through the external disassembly port 131, which can improve the convenience of operation and thus improve the disassembly and assembly efficiency of the motor assembly 22.

[0065] like Figure 4 As shown, in some embodiments, the motor assembly 22 includes a motor mount 221 and a motor 222, with the motor 222 disposed within the motor mount 221. The motor 222 is connected to the cross-flow fan 21 to drive the cross-flow fan 21 to rotate. Figure 5As shown, the volute 12 has a connecting portion 120, and the motor base 221 includes a mounting portion 2211. The mounting portion 2211 is supported on the side of the connecting portion 120 near the external disassembly port 131. The first connecting member is a threaded connecting member. The threaded connecting member passes through the mounting portion 2211 along the direction from the external disassembly port 131 to the motor assembly 22, and the threaded connecting member is threadedly connected to the connecting portion 120. In this way, the threaded connector can be inserted into the mounting part 2211 along (or roughly along) the axis of the cross-flow impeller 21 and threadedly connected to the connecting part 120, thereby achieving a fixed connection between the electrode assembly 22 and the volute 12. When it is necessary to disassemble the fan component 2, the threaded connector can be unscrewed along (or roughly along) the axis of the cross-flow impeller 21, so that the threaded connector is detached from the motor assembly 22 and the volute 12. After the threaded connector is released from its fixing function, the mounting part 2211 can move relative to the connecting part 120 through the external disassembly port 131, that is, the motor base 221 can move relative to the volute 12 and through the external disassembly port 131. At the same time, the motor 222 moves with the motor base 221. Therefore, when the motor assembly 22 is detached from the volute 12, interference with the connecting part 120 on the volute 12 can be avoided, further improving the disassembly and assembly efficiency of the motor assembly 22.

[0066] like Figure 5 As shown, in some embodiments, the motor assembly 22 includes a motor mount 221 and a motor 222. The motor 222 is disposed within the motor mount 221 and connected to the cross-flow fan 21. The motor mount 221 is covered by an inner disassembly port 132 and is sealed to the volute 12. In conjunction with the above embodiments, the cross-flow fan 21 is disposed within the volute 12. The cross-flow fan 21 is driven by the motor 222 to generate airflow and drive the airflow along the volute 12. The connection between the cross-flow fan 21 and the motor 222 needs to be through the inner disassembly port 132 on the volute 12. By covering the inner disassembly port 132 with the motor mount 221 and sealing it to the volute 12, the sealing effect can be increased, which helps to prevent air leakage through the inner disassembly port 132. All airflow is then delivered from the air outlet 103 of the air conditioner 100, improving the air delivery efficiency of the air conditioner 100.

[0067] like Figure 5 As shown, in some embodiments, the motor mount 221 includes an end plate 2212, which can cover the inner disassembly port 132, thereby reducing airflow leakage from the inner disassembly port 132. Figures 8-9 , Figures 11-12As shown, the motor mount 221 and the volute 12 are sealed together by a sealing structure 3. The sealing structure 3 includes a first rib 31 and a second rib 32. One of the first rib 31 and the second rib 32 protrudes from the end plate 2212 toward the volute 12, and the other protrudes from the volute 12 toward the motor mount 221. The first rib 31 is arranged around the inner disassembly port 132, and the second rib 32 is arranged around the first rib 31. That is to say, the first rib 31 surrounding the inner disassembly port 132 can increase the sealing range and reduce the probability of air leakage. The first rib 31 has a first sealing surface perpendicular to its protruding direction, and the second rib 32 has a second sealing surface perpendicular to its protruding direction. The first sealing surface and the second sealing surface are opposite to each other and at least partially overlap. The first rib 31 and the second rib 32 form a mechanical seal structure 3, which is beneficial to improving the sealing effect.

[0068] like Figures 8-9 , Figures 11-12 As shown, for example, a first rib 31 is provided on the volute 12, and the first rib 31 protrudes from the volute 12 toward the motor base 221; a second rib 32 is provided on the motor base 221, and the second rib 32 protrudes from the motor base 221 toward the volute 12; the inner disassembly port 132 is a circular opening, the first rib 31 is constructed as an annular structure with the inner disassembly port 132 as the same center, the second rib 32 is an annular structure with the first rib 31 as the same center, the first sealing surface is the annular surface of the first rib 31, the second sealing surface is the annular surface of the second rib 32, and in the radial direction of the first rib 31 and the second rib 32, the first sealing surface and the second sealing surface at least partially overlap.

[0069] Optionally, the first rib 31 is disposed on the motor base 221, and the first rib 31 protrudes from the volute 12 toward the motor base 221; the second rib 32 is disposed on the volute 12, and the second rib 32 protrudes from the motor base 221 toward the volute 12.

[0070] In addition, the second rib 32 is arranged around the first rib 31. When the motor base 221 is installed into the inner disassembly port 132 of the volute 12, the second rib 32 is sleeved on the radial outer side of the first rib 31. The first rib 31 and the second rib 32 can also realize the installation and positioning function of the motor base 221.

[0071] It should be noted that the motor mount 221 includes an end plate 2212, which covers the inner disassembly port 132. The mounting part 2211 is connected to the end plate 2212, and the inner disassembly port 132 has a projection on the end plate 2212, and the projection is offset from the end plate 2212 to improve the sealing effect of the end plate 2212 on the inner disassembly port 132.

[0072] Preferably, the mounting portion 2211 includes a plurality of mounting portions 2211, which are spaced apart and arranged around the outer periphery of the end plate 2212.

[0073] like Figures 5-7 As shown, in some embodiments, the volute 12 includes a first volute 121 and a second volute 122, which are located on opposite radial sides of the cross-flow impeller 21 and are detachably connected. The motor mount 221 also includes an end cap assembly 2213, which is connected to the side of the end plate 2212 near the external disassembly port 131 to form a receiving space 223 between the end cap assembly 2213 and the end plate 2212, in which the motor 222 is disposed. The end cap assembly 2213 includes a first end cap 22131 and a second end cap 22132, which are detachably connected. The first end cap 22131 is sealed to the first volute 121, and the second end cap 22132 is sealed to the second volute 122. When the air conditioner 100 is installed at the factory, the second volute 122 is sealed to the second end cover 22132, and the motor 222 can be installed between the second end cover 22132 and the end plate 2212. The cross-flow fan 21 is installed in the second volute 122. The first end cover 22131 is sealed to the first volute 121. Finally, the first end cover 22131 and the first volute 121 are assembled onto the second end cover 22132 and the second volute 122, thereby improving the efficiency of the air conditioner 100's factory assembly.

[0074] like Figure 13 and Figure 14 As shown, for example, the air conditioner 100 also includes an air outlet grille 18 and an air guide plate 19. The air outlet grille 18 prevents foreign objects from entering the interior of the air conditioner 100, and the air guide plate 19 is located at the air outlet 103 and guides the airflow direction. The first volute 121 communicates with the air outlet 103 of the air conditioner 100, and the air outlet grille 18 is installed at the airflow outlet of the first volute 121, so that the air outlet grille 18 and the air guide plate 19 are offset. Thus, when the air conditioner 100 is installed at the factory, the first end cover 22131 is sealed to the first volute 121, the air outlet grille 18 is installed at the airflow outlet of the first volute 121, and the first end cover 22131 and the first volute 121 are assembled onto the second end cover 22132 and the second volute 122. This can reduce the installation difficulty of the air outlet grille 18 and further improve the efficiency of the air conditioner 100's factory assembly.

[0075] In summary, by dividing the volute 12 and the end cover assembly 2213 into two parts, it is easier to process the volute 12, which facilitates the installation of the cross-flow fan 21 and the air outlet grille 18, greatly reducing the installation difficulty of the air conditioner 100.

[0076] Alternatively, the volute 12 can also be integrally molded.

[0077] like Figure 4 and Figure 13 As shown, in some embodiments, the cross-flow impeller 21 has a mating portion 211 located at the end of the cross-flow impeller 21 away from the motor assembly 22 along its axial direction. The volute 12 has a support portion 124 at the corresponding end of the mating portion 211. The mating portion 211 and the support portion 124 are inserted and removed along the axial direction of the cross-flow impeller 21. The mating between the mating portion 211 and the support portion 124 serves two purposes: firstly, it provides positioning and feedback for the installation of the cross-flow impeller 21; secondly, it allows the cross-flow impeller 21 to rotate relative to the volute 12. The mating between the mating portion 211 and the support portion 124 improves the smoothness and stability of the rotation of the cross-flow impeller 21.

[0078] Optionally, the mating part 211 can be a rotating shaft, and the support part 124 can be a bearing; alternatively, the mating part 211 can be a bearing, and the support part 124 can be a rotating shaft.

[0079] For example, one end of the corresponding mating part 211 of the volute 12 has a support part 124, which is disposed on the support part 124 mounting position of the volute 12. In conjunction with the above embodiment, the first volute 121 is provided with a first support part mounting position 1241, and the second volute 122 is provided with a second support part mounting position 1242.

[0080] In some embodiments, the air conditioner body 1 further includes a wiring box 4, which is installed on the side of the motor assembly 22 near the external disassembly port 131. The air conditioner body 1 includes a clearance space located inside the housing 11 and adjacent to the wiring box 4. The wiring box 4 is detachably connected to the motor assembly 22. When the connection between the wiring box 4 and the motor assembly 22 is released, the wiring box 4 can be moved to the clearance space to avoid the motor assembly 22.

[0081] Therefore, when it is necessary to disassemble the motor component 2, the connection between the wiring box 4 and the motor assembly 22 can be disconnected first, and then the wiring box 4 can be moved to a clearance space so that the wiring box 4 is moved to a clearance position that no longer blocks the motor assembly 22. At this time, the motor component 2 can be removed from the external disassembly port 131.

[0082] For example, the volute 12 includes an air outlet structure 125 located above the motor assembly 22, the wiring box 4 extends vertically, and the air conditioner body includes a socket structure 5 that engages with the lower end of the wiring box 4, with the upper end of the wiring box 4 lower than the air outlet structure 125. For example, the socket structure 5 defines a top-opening socket, and the lower end of the wiring box 4 is inserted downward into the socket structure 5, thereby facilitating quick assembly and disassembly.

[0083] Therefore, by setting the upper end of the wiring box 4 lower than the air outlet structure 125, when the connection between the wiring box 4 and the motor assembly 22 is released, the air outlet structure 125 will not obstruct the movement of the wiring box 4, allowing it to be moved to the clearance space. It is worth noting that before moving the wiring box 4 to the clearance space, the lower end of the wiring box 4 can be pulled out from the socket structure 5, making it easier to move it to the clearance space. Alternatively, when the insertion clearance between the wiring box 4 and the socket structure 5 is large, the lower end of the wiring box 4 can be rotated into the clearance space without pulling it out of the socket structure 5.

[0084] Alternatively, in other embodiments of this application, the wiring box 4 can be configured to be removed from the external access port 131. For example, the wiring box 4 can be configured such that its upper end is lower than the upper edge of the external access port 131. After disconnecting the wiring box 4 from the motor assembly 22, the lower end of the wiring box 4 can be pulled out of the socket structure 5, and then the wiring box 4 can be removed from the external access port 131. It is worth noting that when it is necessary to remove the wiring box 4 from the external access port 131, the wires inside the wiring box 4 must first be pulled out of the wiring box 4.

[0085] In addition, obstacles such as wiring box 4 that block the side of motor assembly 22 near external access port 131 can be designed with reference to wiring box 4 to meet the disassembly and assembly requirements of motor assembly 22.

[0086] In some embodiments, the electrical control components (e.g., the control box) of the air conditioner body 1 are connected to the wires of the motor assembly 22 via a power connector. The power connector is positioned corresponding to the external access port 131 (i.e., when the external access port 131 is open, the power connector inside can be observed along the through direction of the external access port 131), so that the power connector can be inserted and removed from the external access port 131. Thus, when it is necessary to disassemble the motor assembly 2, the power connector can be first disconnected from the external access port 131, and then the motor assembly 2 can be removed from the external access port 131, thereby avoiding the power connection of the motor assembly 2 from affecting the removal of the motor assembly 2 from the external access port 131. In this way, by setting the power connector to be positioned opposite the external access port 131 so that it can be inserted and removed through the external access port 131, it is convenient to operate uniformly from the external access port 131 without disassembling other shell walls of the housing 11.

[0087] In some embodiments, such as Figure 17 As shown, the air conditioner 100 is a window air conditioner and includes an indoor unit 101 suitable for installation indoors and an outdoor unit 102 suitable for installation outdoors. The indoor unit 101 includes an air conditioner body 1 and a fan assembly 2. The window divides the integrated window air conditioner into the indoor unit 101 and the outdoor unit 102. The first air inlet 101, the second air inlet 102, and the air outlet 103 are all located indoors.

[0088] The following is combined with Figures 1-17 Here is a specific example.

[0089] like Figure 1 and Figure 13 As shown, the air conditioner 100 has a first air inlet 101, a second air inlet 102, and an air outlet 103. The air outlet 103 faces the room and can deliver air to the front of the air conditioner 100. The first air inlet 101 and the air outlet 103 are both located on the front side of the air conditioner 100, and the second air inlet 102 is located on the lower side of the air conditioner 100. Multiple air inlets improve the heat exchange efficiency of the air conditioner 100.

[0090] like Figure 13 and Figure 14 As shown, the air conditioner 100 includes an air conditioner body 1, which includes a heat exchanger 15. The heat exchanger 15 is positioned opposite to the first air inlet 101 and opposite to the second air inlet 102, ensuring that the airflow from the air inlets passes through the heat exchanger 15 before being discharged from the air outlet 103. The air conditioner body 1 also includes a casing 11 and a volute 12. The volute 12 is disposed inside the casing 11, and the first air inlet 101, the second air inlet 102, and the air outlet 103 are formed on the casing 11. The volute 12 has an airflow inlet and an airflow outlet. The heat exchanger 15 surrounds the airflow inlet, and the airflow inlet communicates with the first air inlet 101 and the second air inlet 102. The airflow outlet communicates with the air outlet 103. The volute 12 includes a first volute 121 and a second volute 122. The first volute 121 is disposed in front of the second volute 122. An airflow passage is defined between the first volute 121 and the second volute 122. That is, after the airflow passes through the first air inlet 101 or the second air inlet 102, it passes through the heat exchanger 15 and then flows in the airflow passage, finally being delivered to the air outlet 103 through the airflow outlet on the first volute 121. Figure 16 As shown, the airflow direction is generally from the lower side of the air conditioner 100 to the upper side of the air conditioner 100. The air conditioner body 1 also includes a water receiving tank 16, which is disposed on the lower side of the heat exchanger 15 to receive condensate on the air conditioner 100.

[0091] like Figure 4 and Figure 13As shown, the air conditioner 100 also includes a fan component 2, which drives airflow to form an airflow. The fan component 2 is located inside the volute 12 and downstream of the airflow. The fan component 2 is positioned at the top of the air conditioner 100 and offset from the heat exchanger 15, making the structure of the air conditioner 100 more compact. The fan component 2 includes a cross-flow impeller 21 and a motor assembly 22. The cross-flow impeller 21 has a larger axial dimension than its radial dimension. The cross-flow impeller 21 is arranged in the volute 12 along a left-right direction, and the motor assembly 22 is located to the right of the cross-flow impeller 21. Figure 7 , Figure 10 and Figure 15 As shown, the output shaft of the motor assembly 22 is connected to the right side of the cross-flow fan 21. The left side of the cross-flow fan 21 has a mating part 211, which is constructed as a rotating shaft. The left side of the volute 12 has a support part 124, which is constructed as a bearing. The rotating shaft can be inserted into and removed from the bearing. Both the first volute 121 and the second volute 122 have reserved bearing mounting positions, that is, the first volute 121 has a first support mounting position 1241, and the second volute 122 has a second support mounting position 1242.

[0092] like Figure 2 As shown, when the fan component 2 is being maintained, the fan component 2 can be moved in the left and right directions relative to the air conditioner body 1 to achieve the disassembly or installation of the fan component 2 and the air conditioner body 1.

[0093] like Figure 2 and Figure 3 As shown, the air conditioner body 1 includes a service cover, which is detachably connected to the housing 11. When the service cover is removed from the housing 11, an external disassembly port 131 is exposed. The motor assembly 22 is fixedly connected to the volute 12. The fixed connection between the volute 12 and the motor assembly 22 can be released through the external disassembly port 131, thereby allowing the motor assembly 22 to be disassembled relative to the volute 12. The volute 12 has an internal disassembly port 132, and the cross-flow fan 21 can move left and right relative to the internal disassembly port 132, thereby allowing the cross-flow fan 21 to be disassembled and assembled relative to the volute 12.

[0094] like Figure 5 As shown, the motor assembly 22 includes a motor base 221, which includes an end plate 2212. The end plate 2212 covers the inner disassembly port 132. After the fixed connection between the volute 12 and the motor assembly 22 is released, the end plate 2212 can be removed from the inner disassembly port 132, thereby allowing the cross-flow fan wheel 21 to be pulled out from the right side.

[0095] like Figure 5As shown, the first volute 121 has at least two connecting portions 120 spaced apart, and the second volute 122 has at least two connecting portions 120 spaced apart. The mounting portion 2211 extends radially along the outer periphery of the end plate 2212. The end plate 2212 is located on the right side of the volute 12. The mounting portion 2211 corresponds to each connecting portion 120, and the mounting portion 2211 is supported on the right side of the connecting portion 120. The first connecting member is a threaded connector that can penetrate the mounting portion 2211 to connect to the connecting portion 120, thus fixing the volute 12 to the end plate 2212. The first connecting member can be removed and installed through the external disassembly port 131.

[0096] like Figure 6 and Figure 10 As shown, the motor mount 221 includes an end cover assembly 2213, which includes a first end cover 22131 and a second end cover 22132. The first end cover 22131 is located in front of the second end cover 22132 and is connected to the first volute 121. The second end cover 22132 is connected to the second volute 122. The end plate 2212 is divided into front and rear parts. A partial receiving space 223 is defined between the first end cover 22131 and the front end plate 2212, and another partial receiving space 223 is defined between the second end cover 22132 and the rear end plate 2212. The receiving space 223 can accommodate the motor 222. The first end cover 22131 and the second end cover 22132 are inserted and positioned together and connected by threaded parts.

[0097] like Figure 8 and Figure 9 , Figure 11 and Figure 12 As shown, a sealing structure 3 is provided between the first volute 121 and the front end plate 2212, and a sealing structure 3 is provided between the second volute 122 and the rear end plate 2212. Both the first volute 121 and the second volute 122 are provided with a first rib 31, which protrudes along the volute 12 towards the end plate 2212; both the front end plate 2212 and the rear end plate 2212 are provided with a second rib 32, which protrudes along the end plate 2212 towards the volute 12. The first rib 31 is arranged around the inner disassembly port 132, and the second rib 32 is arranged around the first rib 31.

[0098] like Figure 13 and Figure 16 As shown, during the disassembly and assembly process, the cross-flow fan 21 tends to move downwards under the action of gravity. The guide 17 extends into the airflow outlet and air outlet grille 18 of the first volute 121, hooks the side of the cross-flow fan 21 away from the motor assembly 22, and lifts the cross-flow fan 21 upwards, which can better install the cross-flow fan 21.
