[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0046] The air conditioner 100 according to the 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 casing 11 and a volute 12, wherein the volute 12 is disposed in the casing 11, and the fan component 2 is disposed in the casing 11. The casing 11 can protect the volute 12 and the fan component 2, thereby improving the stability of the operation of the air conditioner 100.

[0048] like Figure 4 As shown, the fan component 2 includes a crossflow fan wheel 21 and a motor assembly 22. The motor assembly 22 can drive the crossflow fan wheel 21 to rotate, and the crossflow fan wheel 21 can form an airflow and drive the airflow to flow. The crossflow fan wheel 21 is arranged inside the volute 12, and the volute 12 forms an airflow channel and can guide the flow path of the airflow. The airflow flows along the volute 12 driven by the crossflow fan wheel 21.

[0049] The crossflow wind wheel 21 is arranged inside the volute 12. Optionally, the crossflow wind wheel 21 can be arranged upstream of the volute 12; the crossflow wind wheel 21 can also be arranged midstream of the volute 12; optionally, the crossflow wind wheel 21 can also be arranged downstream of the volute 12. The position of the crossflow wind wheel 21 is not limited here.

[0050] Combination Figure 5 and Figure 6 As shown, the motor assembly 22 is arranged outside the volute 12, and the motor assembly 22 is connected to one axial end of the crossflow fan wheel 21. When the air conditioner 100 is in operation, the motor assembly 22 drives the crossflow fan wheel 21 to rotate to form an airflow. When the fan component 2 is disassembled and assembled, the motor assembly 22 is fixed to the crossflow fan wheel 21, and when the motor assembly 22 is moved, the motor assembly 22 can drive the crossflow fan wheel 21 to move in the volute 12. The motor assembly 22 can better hold the crossflow fan wheel 21, which is conducive to improving the convenience of disassembly and assembly of the fan component 2, and during the movement of the fan component 2, holding the motor assembly 22 can reduce the probability of damaging the blades of the crossflow fan wheel 21.

[0051] like Figure 2 As shown, the air conditioner body 1 has a disassembly opening 13, which is arranged on one side of the air conditioner body 1 close to the motor assembly 22. The disassembly opening 13 can pass through the fan component 2, and the fan component 2 moves along the axial direction of the crossflow impeller 21. The fixed connection between the fan component 2 and the air conditioner body 1 can be released from the disassembly opening 13, so that the fan component 2 can be disassembled from the disassembly opening 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 opening 13, and 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 loaded through the disassembly opening 13 by moving along the axial direction of the crossflow impeller 21. For example, a maintenance worker can extend his hand or a tool into the disassembly opening 13 to contact the fixed connection between the fan component 2 and the air conditioner body 1, so that the fan component 2 and the air conditioner body 1 are separable.

[0052] For example, when the disassembly opening 13 is located on the side of the air conditioner body 1, the fan component 2 can be disassembled by side extraction.

[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 opening 13. When the fan component 2 needs to be taken out, the fixed connection between the fan component 2 and the air conditioner body 1 can be released through the disassembly opening 13, and then the fan component 2 can be pulled out from the disassembly opening 13 along the axial direction of the crossflow impeller 21; when the fan component 2 needs to be assembled to the air conditioner body 1, the fan component 2 is pushed into the air conditioner body 1 from the disassembly opening 13 along the axial direction of the crossflow impeller 21, and the fixed connection between the fan component 2 and the air conditioner body 1 is restored through the disassembly opening 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 and assembly opening 13 of the air conditioner body 1, and the fan component 2 passes through the disassembly and assembly opening 13 along the axial direction of the crossflow impeller 21. Since the motor assembly 22 is connected to one axial end of the crossflow impeller 21, the motor assembly 22 and the crossflow impeller 21 can pass through the disassembly and assembly opening 13 along the axial direction of the crossflow impeller 21, which is conducive to avoiding interference between the motor assembly 22 and the crossflow impeller 21 and improving assembly efficiency.

[0056] The disassembly opening 13 is arranged on a side of the air conditioner body 1 close to the motor assembly 22. When the fan component 2 is disassembled, the motor assembly 22 in the fan component 2 is first moved out of the air conditioner body 1, and then the crossflow impeller 21 is moved out of the air conditioner body 1. When the fan component 2 is installed, the crossflow impeller 21 in the fan component 2 is first entered into the air conditioner body 1, and then the motor assembly 22 is entered into the air conditioner body 1.

[0057] Different from the related art, the air conditioner 100 of the embodiment of the present application can realize the assembly or disassembly between the fan component 2 and the air conditioner body 1 through the disassembly opening 13 on the air conditioner body 1, and there is no need to disassemble the volute 12, thereby improving the disassembly efficiency and assembly efficiency, improving the convenience of operation, and thus making the maintenance and cleaning of the air conditioner 100 simpler and more convenient. In the related art, in order to disassemble the volute in the casing, the casing needs to be disassembled enough until there is an operating space for disassembling the volute. In the embodiment of the present application, since the disassembly of the volute 12 is cancelled, the operating space for taking out the fan component 2 can be reduced, that is, the disassembly steps of the casing 11 are reduced.

[0058] According to the air conditioner 100 of the embodiment of the utility model, the fan component 2 can be independently disassembled and assembled from the disassembly and assembly 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 the disassembly efficiency 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 Fig.14As shown, in some embodiments, the disassembly opening 13 includes an external disassembly opening 131 provided on the housing 11, and the motor assembly 22 is provided corresponding to the external disassembly opening 131, that is, when the external disassembly opening 131 is opened, the motor assembly 22 inside thereof can be observed along the penetration direction of the external disassembly opening 131, and on the projection plane perpendicular to the axial direction of the crossflow impeller 21, the projection of the fan component 2 is located within the projection of the external disassembly opening 131. That is, on the projection plane perpendicular to the axial direction of the crossflow impeller 21, the projection of the motor assembly 22 is located within the projection of the external disassembly opening 131, and the projection of the crossflow impeller 21 is also located within the projection of the external disassembly opening 131. Therefore, the crossflow impeller 21 and the motor assembly 22 of the fan component 2 are arranged along the axial direction of the crossflow impeller 21, and can directly pass through the external disassembly opening 131 along the axial direction of the crossflow impeller 21 without adjusting the angle of the fan component 2 when passing through the external disassembly opening 131, which is beneficial to avoid interference between the fan component 2 and the air-conditioning body 1 and improve the convenience of disassembly and assembly.

[0060] Exemplarily, the front of the housing 11 is provided with an air outlet 103, and the external disassembly opening 131 is provided on the side of the housing 11. Usually, the side of the air outlet 103 is provided facing the user (for example, on the front side), and the external disassembly opening 131 and the air outlet 103 are provided on different sides, so that the external disassembly opening 131 can be located on the side that is not observed by the user (for example, on the left or right side), and in this case, the fan component 2 can be disassembled by side drawing. However, the present application is not limited to this, and in some other embodiments of the present application, the external disassembly opening 131 and the air outlet 103 can also be provided on the same side.

[0061] Exemplarily, the disassembly opening 13 includes an outer disassembly opening 131 and an inner disassembly opening 132. The outer disassembly opening 131 is provided on the housing 11, and the motor assembly 22 is provided corresponding to the outer disassembly opening 131; the inner disassembly opening 132 is provided on the volute 12 and is covered by the motor assembly 22. On the projection plane perpendicular to the axial direction of the crossflow impeller 21, the projection of the motor assembly 22 is located within the projection of the outer disassembly opening 131, and the projection of the crossflow impeller 21 is located within the projection of the inner disassembly opening 132 and within the projection of the outer disassembly opening 131. When the motor assembly 22 is removed, the inner disassembly opening 132 is equivalent to being opened, and the crossflow impeller 21 can pass through the inner disassembly opening 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, and the motor assembly 22 can be removed through the external disassembly port 131. The sizes of the crossflow wind wheel 21 on the projection surface are smaller than the sizes of the internal disassembly port 132 and the external disassembly port 131 on the projection surface, and the crossflow wind wheel 21 can be removed through the internal disassembly port 132 and the external disassembly port 131 along its axial direction.

[0062] In combination with the above-mentioned embodiment, the volute 12 is arranged inside the casing 11, and the inner disassembly opening 132 is arranged inside the outer disassembly opening 131. When the crossflow impeller 21 is disassembled from the air conditioner body 1, it first passes through the inner disassembly opening 132 and then passes through the outer disassembly opening 131. The motor assembly 22 is arranged corresponding to the outer disassembly opening 131, and the motor assembly 22 is arranged outside the volute 12, so the motor assembly 22 only passes through the outer disassembly opening 131 but not through the inner disassembly opening 132. During the disassembly and assembly process of the fan component 2, the motor assembly 22 drives the crossflow impeller 21 to move, and the motor assembly 22 is easier to hold. The motor assembly 22 can be removed through the outer disassembly opening 131, and the crossflow impeller 21 can be removed through the inner disassembly opening 132 and the outer disassembly opening 131. In summary, the crossflow impeller 21 and the motor assembly 22 of the fan component 2 are arranged along the axial direction of the crossflow impeller 21, and can directly pass through the disassembly and assembly port 13 along the axial direction of the crossflow impeller 21 without adjusting the angle of the fan component 2 when passing through the disassembly and assembly port 13, which is beneficial to avoid interference between the fan component 2 and the air-conditioning body 1 and improve the convenience of disassembly and assembly.

[0063] like Figure 1-Figure 3 As shown, in some embodiments, the air conditioner body 1 includes an access panel 14 for covering the external disassembly opening 131, and the access panel 14 is movably connected to the housing 11. Optionally, the access panel 14 is detachably connected to the housing 11. The access panel 14 can cover the vacancy of the disassembly opening 131, maintain the integrity of the appearance, protect the interior of the air conditioner 100, and improve the stability of operation.

[0064] In some embodiments, the motor assembly 22 is fixedly connected to the volute 12 via a first connector, and the first connector is arranged corresponding to the external disassembly port 131 (i.e., when the external disassembly port 131 is opened, the first connector on the inner side thereof can be observed along the penetration 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 stability of the operation of the air conditioner 100. In combination with the above-mentioned embodiments, after removing the inspection panel 14, the external disassembly port 131 is opened, the first connector can be disassembled and assembled through the external disassembly port 131, and the motor assembly 22 can be pulled out of the external disassembly port 131 or assembled into the air conditioner 100, which can improve the convenience of operation, thereby improving 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 base 221 and a motor 222, and the motor 222 is disposed in the motor base 221. The motor 222 is connected to the crossflow impeller 21 to drive the crossflow impeller 21 to rotate. Figure 5As shown, the volute 12 has a connecting portion 120, and the motor seat 221 includes a mounting portion 2211, and the mounting portion 2211 is supported on a side of the connecting portion 120 close to the external disassembly port 131, and the first connecting member is a threaded connecting member, which 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 portion 2211 along (or substantially along) the axis of the crossflow impeller 21 and threadedly connected to the connecting portion 120, thereby achieving a fixed connection between the electrode assembly 22 and the volute 12. When the fan component 2 needs to be disassembled, the threaded connector can be unscrewed along (or substantially along) the axis of the crossflow impeller 21, so that the threaded connector is detached from the motor assembly 22 and the volute 12. In this way, after the threaded connector releases the connection and fixing function, the mounting portion 2211 can pass through the external disassembly port 131 relative to the connecting portion 120, that is, the motor seat 221 can move relative to the volute 12 and pass through the external disassembly port 131, and at the same time, the motor 222 moves with the motor seat 221. Therefore, when the motor assembly 22 is detached from the volute 12, interference with the connecting portion 120 on the volute 12 can be avoided, thereby 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 seat 221 and a motor 222. The motor 222 is arranged in the motor seat 221 and connected to the crossflow impeller 21. The motor seat 221 is covered with an inner disassembly opening 132 and is sealed with the volute 12. In combination with the above embodiments, the crossflow impeller 21 is arranged in the volute 12. The crossflow impeller 21 is driven by the motor 222 to form an airflow and drive the airflow to flow along the volute 12. The connection between the crossflow impeller 21 and the motor 222 needs to pass through the inner disassembly opening 132 on the volute 12. By covering the motor seat 221 on the inner disassembly opening 132 and sealing with the volute 12, the sealing effect can be increased, which is conducive to avoiding air leakage from the inner disassembly opening 132, sending all the airflow from the air outlet 103 of the air conditioner 100, and improving the air supply efficiency of the air conditioner 100.

[0067] like Figure 5 As shown, in some embodiments, the motor base 221 includes an end plate 2212, and the end plate 2212 can cover the inner disassembly opening 132, which is helpful to reduce the leakage of airflow from the inner disassembly opening 132. Figure 8-Figure 9 , Figure 11-Figure 12As shown, the motor seat 221 and the volute 12 are sealed together through the sealing structure 3, and the sealing structure 3 includes a first convex rib 31 and a second convex rib 32. One of the first convex rib 31 and the second convex rib 32 protrudes from the end plate 2212 toward the volute 12, and the other protrudes from the volute 12 toward the motor seat 221. The first convex rib 31 is arranged around the inner disassembly and assembly port 132, and the second convex rib 32 is arranged around the first convex rib 31. That is to say, the first convex rib 31 surrounds the inner disassembly and assembly port 132, which can increase the sealing range and reduce the probability of air leakage; the first convex rib 31 has a first sealing surface perpendicular to its protruding direction, and the second convex rib 32 has a second sealing surface perpendicular to its protruding direction. The first sealing surface is opposite to the second sealing surface and at least partially overlaps. The first convex rib 31 and the second convex rib 32 form a mechanical sealing structure 3, which is conducive to improving the sealing effect.

[0068] like Figure 8-Figure 9 , Figure 11-Figure 12 As shown, for example, the first rib 31 is arranged on the volute 12, and the first rib 31 protrudes from the volute 12 toward the direction of the motor seat 221; the second rib 32 is arranged on the motor seat 221, and the second rib 32 protrudes from the motor seat 221 toward the direction of the volute 12; the inner disassembly and assembly port 132 is a circular opening, the first rib 31 is constructed as an annular structure arranged cocentrically with the inner disassembly and assembly port 132, the second rib 32 is an annular structure arranged cocentrically with the first rib 31, the first sealing surface is the annular surface of the first rib 31, and 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 convex rib 31 is disposed on the motor seat 221, and the first convex rib 31 protrudes from the volute 12 toward the motor seat 221; the second convex rib 32 is disposed on the volute 12, and the second convex rib 32 protrudes from the motor seat 221 toward the volute 12;

[0070] In addition, the second rib 32 is arranged around the first rib 31. When the motor seat 221 is installed to the inner disassembly and assembly 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 seat 221.

[0071] It should be noted that the motor seat 221 includes an end plate 2212, which covers the inner disassembly opening 132. The mounting portion 2211 is connected to the end plate 2212, and the inner disassembly opening 132 has a projection on the end plate 2212, and the projection is staggered with the end plate 2212 to improve the sealing effect of the end plate 2212 on the inner disassembly opening 132.

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

[0073] like Figure 5-Figure 7 As shown, in some embodiments, the volute 12 includes a first volute 121 and a second volute 122, the first volute 121 and the second volute 122 are located on both radial sides of the crossflow impeller 21, and the first volute 121 and the second volute 122 are detachably connected. The motor seat 221 also includes an end cover assembly 2213, and the end cover assembly 2213 is connected to a side of the end plate 2212 close to the external disassembly port 131 to form an accommodation space 223 between the end cover assembly 2213 and the end plate 2212, and the motor 222 is arranged in the accommodation space 223. The end cover assembly 2213 includes a first end cover 22131 and a second end cover 22132, the first end cover 22131 and the second end cover 22132 are detachably connected, the first end cover 22131 is sealed with the first volute 121, and the second end cover 22132 is sealed with the second volute 122. When the air conditioner 100 is installed at the factory, the second volute 122 is sealed with the second end cover 22132, the motor 222 can be installed between the second end cover 22132 and the end plate 2212, and the crossflow impeller 21 is installed in the second volute 122; the first end cover 22131 is sealed with the first volute 121; finally, the first end cover 22131 and the first volute 121 are assembled to the second end cover 22132 and the second volute 122, thereby improving the efficiency of the factory assembly of the air conditioner 100.

[0074] like Fig.13 and Fig.14 As shown, for example, the air conditioner 100 further includes an air outlet grille 18 and an air guide plate 19. The air outlet grille 18 can prevent foreign objects from intruding into the interior of the air conditioner 100. The air guide plate 19 is arranged at the air outlet 103 and guides the air flow direction. The first volute 121 is connected to the air outlet 103 of the air conditioner 100, and the air outlet grille 18 is installed at the air flow outlet of the first volute 121, so that the air outlet grille 18 and the air guide plate 19 are staggered. Therefore, when the air conditioner 100 is installed at the factory, the first end cover 22131 is sealed with the first volute 121, and the air outlet grille 18 is installed at the air flow outlet of the first volute 121, and the first end cover 22131 and the first volute 121 are assembled to the second end cover 22132 and the second volute 122, which can reduce the installation difficulty of the air outlet grille 18 and further improve the efficiency of the factory assembly of the air conditioner 100.

[0075] In summary, by dividing the volute 12 and the end cover assembly 2213 into two parts, the volute 12 can be easily processed, which is conducive to facilitating the installation of the crossflow impeller 21 and the air outlet grille 18, greatly reducing the difficulty of installing the air conditioner 100.

[0076] Alternatively, the volute 12 may also be integrally formed.

[0077] like Figure 4 and Fig.13 As shown, in some embodiments, the crossflow impeller 21 has a matching portion 211, which is located at one end of the crossflow impeller 21 in the axial direction away from the motor assembly 22, and one end of the volute 12 corresponding to the matching portion 211 has a supporting portion 124, and the matching portion 211 and the supporting portion 124 are plugged in and disassembled along the axial direction of the crossflow impeller 21. The matching between the matching portion 211 and the supporting portion 124 can, on the one hand, position and feedback the installation of the crossflow impeller 21, and on the other hand, the crossflow impeller 21 can rotate relative to the volute 12, and the matching between the matching portion 211 and the supporting portion 124 can improve the smoothness and stability of the rotation of the crossflow impeller 21.

[0078] Optionally, the matching portion 211 may be a rotating shaft, and the supporting portion 124 may be a bearing; optionally, the matching portion 211 may be a bearing, and the supporting portion 124 may be a rotating shaft.

[0079] For example, one end of the volute 12 corresponding to the matching portion 211 has a support portion 124, which is arranged on the support portion 124 installation position of the volute 12. In combination with the above embodiment, the first volute 121 is provided with a first support portion installation position 1241, and the second volute 122 is provided with a second support portion installation position 1242.

[0080] In some embodiments, the air conditioner body 1 also includes: a wiring box 4, which is installed on a side of the motor assembly 22 close to the external disassembly port 131, and the air conditioner body 1 includes an avoidance space located in the casing 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 avoidance space to avoid the motor assembly 22.

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

[0082] Exemplarily, the volute 12 includes an air outlet structure 125 located above the motor assembly 22, the wiring box 4 extends in the up-down direction, the air conditioner body includes a socket structure 5 plugged with the lower end of the wiring box 4, and the upper end of the wiring box 4 is lower than the air outlet structure 125. For example, the socket structure 5 defines a socket with an open top, and the lower end of the wiring box 4 is inserted downward into the socket structure 5, so as to facilitate quick disassembly and assembly.

[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 block the movement of the wiring box 4, and the wiring box 4 can be moved to the escape space. It is worth noting that before moving the wiring box 4 to the escape space, the lower end of the wiring box 4 can be pulled out from the socket structure 5, so that the wiring box 4 can be moved to the escape space more easily. Alternatively, when the plug-in margin between the wiring box 4 and the socket structure 5 is large, the lower end of the wiring box 4 can be replaced by the socket structure 5 instead of being pulled out. Instead, the wiring box 4 can be rotated into the escape space by swinging around the lower end.

[0084] Alternatively, in other embodiments of the present application, the wiring box 4 may be configured to be detachable from the external disassembly opening 131. For example, the wiring box 4 may be configured such that its upper end is lower than the upper edge of the external disassembly opening 131. After the connection between the wiring box 4 and the motor assembly 22 is released, the lower end of the wiring box 4 is pulled out from the socket structure 5, and then the wiring box 4 is removed from the external disassembly opening 131. It is worth noting that when the wiring box 4 needs to be removed from the external disassembly opening 131, the wires in the wiring box 4 need to be pulled out from the wiring box 4 first.

[0085] In addition, obstacles such as the wiring box 4 that block the side of the motor assembly 22 close to the external disassembly opening 131 can refer to the design of the wiring box 4 to meet the requirements for disassembly and assembly of the motor assembly 22.

[0086] In some embodiments, the electric control components (such as the electric control box) of the air conditioner body 1 are connected to the wires of the motor assembly 22 through the power connector, and the power connector is arranged corresponding to the external disassembly port 131 (that is, when the external disassembly port 131 is opened, the power connector inside can be observed along the penetration direction of the external disassembly port 131), so that the power connector can be plugged in and out from the external disassembly port 131. Therefore, when it is necessary to disassemble the fan component 2, the power connector can be disassembled from the external disassembly port 131 first, and then the fan component 2 can be disassembled from the external disassembly port 131, so as to avoid the power connection of the fan component 2 affecting the disassembly of the fan component 2 from the external disassembly port 131. In this way, by arranging the power connector to be arranged opposite to the external disassembly port 131 so as to be plugged in and out through the external disassembly port 131, it is convenient to operate uniformly from the external disassembly port 131 without disassembling other shell walls of the casing 11.

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

[0090] like Fig.13 and Fig.14 As shown, the air conditioner 100 includes an air conditioner body 1, and the air conditioner body 1 includes a heat exchanger 15. The heat exchanger 15 is arranged opposite to the first air inlet 101, and the heat exchanger 15 is arranged opposite to the second air inlet 102, so as to ensure that the airflow at the air inlet passes through the heat exchanger 15 and then is sent out from the air outlet 103. The air conditioner body 1 also includes a casing 11 and a volute 12. The volute 12 is arranged inside the casing 11, and the first air inlet 101, the second air inlet 102 and the air outlet 103 are opened on the casing 11.

The heat exchanger 15 is arranged around the air flow inlet, and the air flow inlet is connected with the first air inlet 101 and the second air inlet 102, and the air flow outlet is connected with the air outlet 103. The volute 12 includes a first volute 121 and a second volute 122. The first volute 121 is arranged at the front side of the second volute 122. The first volute 121 and the second volute 122 define an air flow passage, that is, after the air flows through the first air inlet 101 or the second air inlet 102, it passes through the heat exchanger 15, flows in the air flow passage, and is sent to the air outlet 103 from the air flow outlet on the first volute 121. Fig.16 As shown, the air flow direction is roughly 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 arranged on the lower side of the heat exchanger 15 to receive condensed water on the air conditioner 100 .

[0091] like Figure 4 and Fig.13As shown, the air conditioner 100 also includes a fan component 2, which drives the air to flow to form an airflow. The fan component 2 is arranged inside the volute 12 and at the downstream of the airflow. The fan component 2 is arranged at the upper part of the air conditioner 100 and is staggered with the heat exchanger 15, so that the structure of the air conditioner 100 is more compact. The fan component 2 includes a crossflow fan wheel 21 and a motor assembly 22. The size of the crossflow fan wheel 21 in the axial direction is larger than the size in the radial direction. The crossflow fan wheel 21 is arranged in the volute 12 along the left-right direction, and the motor assembly 22 is arranged on the right side of the crossflow fan wheel 21. Figure 7 , Fig.10 and Fig.15 As shown, the output shaft of the motor assembly 22 is connected to the right side of the crossflow impeller 21, the left side of the crossflow impeller 21 has a matching portion 211, the matching portion 211 is configured as a rotating shaft, the left side of the volute 12 has a supporting portion 124, the supporting portion 124 is configured as a bearing, and the rotating shaft can be plugged into the bearing. The first volute 121 and the second volute 122 are both reserved with bearing mounting positions, that is, the first volute 121 is provided with a first supporting portion mounting position 1241, and the second volute 122 is provided with a second supporting portion 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-right direction relative to the air-conditioning body 1 to achieve the disassembly or installation of the fan component 2 and the air-conditioning body 1.

[0093] like Figure 2 and Figure 3 As shown, the air conditioner body 1 includes an inspection cover, which is detachably connected to the casing 11. When the inspection cover is disassembled relative to the casing 11, the external disassembly opening 131 can be exposed. The motor assembly 22 is fixedly connected to the volute 12, and the fixed connection between the volute 12 and the motor assembly 22 can be released through the external disassembly opening 131, so that the motor assembly 22 can be disassembled relative to the volute 12. The volute 12 has an internal disassembly opening 132, and the crossflow impeller 21 can move left and right relative to the internal disassembly opening 132, so that the crossflow impeller 21 can be disassembled relative to the volute 12.

[0094] like Figure 5 As shown, the motor assembly 22 includes a motor seat 221, and the motor seat 221 includes an end plate 2212. The end plate 2212 covers the inner disassembly port 132. After releasing the fixed connection between the volute 12 and the motor assembly 22, the end plate 2212 can remove the inner disassembly port 132, so that the crossflow impeller 21 can be pulled out from the right side.

[0095] like Figure 5As shown, at least two connecting parts 120 are provided on the first volute 121, at least two connecting parts 120 are provided on the second volute 122, and the mounting part 2211 extends radially along the outer circumference of the end plate 2212 to the end plate 2212. The end plate 2212 is provided on the right side of the volute 12, and the mounting part 2211 is provided in a one-to-one correspondence with the connecting part 120. The mounting part 2211 is supported on the right side of the connecting part 120. The first connecting member is a threaded connecting member and can penetrate the mounting part 2211 to connect the connecting part 120, so as to achieve the fixation between the volute 12 and the end plate 2212. The first connecting member can be removed and installed through the external disassembly port 131.

[0096] like Figure 6 and Fig.10 As shown, the motor seat 221 includes an end cover assembly 2213, and the end cover assembly 2213 includes a first end cover 22131 and a second end cover 22132. The first end cover 22131 is arranged at the front side of the second end cover 22132 and the first end cover 22131 is connected to the first volute 121, and the second end cover 22132 is connected to the second volute 122. The end plate 2212 is divided into two parts, front and rear. A part of the accommodation space 223 is defined between the first end cover 22131 and the front end plate 2212, and another part of the accommodation space 223 is defined between the second end cover 22132 and the rear end plate 2212. The accommodation space 223 can accommodate the motor 222. The first end cover 22131 and the second end cover 22131 are inserted and positioned and connected by screws.

[0097] like Figure 8 and Fig. 9 , Fig.11 and Fig.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.

The first convex rib 31 is provided around the inner disassembly and assembly port 132, and the second convex rib 32 is provided around the first convex rib 31.

[0098] like Fig.13 and Fig.16 As shown, during the process of disassembly and assembly, the crossflow wind wheel 21 has a tendency to move downward under the action of gravity. The guide member 17 extends into the airflow outlet and the air outlet grille 18 of the first volute 121, hooks the side of the crossflow wind wheel 21 away from the motor assembly 22 and lifts the crossflow wind wheel 21 upward, so that the crossflow wind wheel 21 can be better installed.
