However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details presented herein. In other instances, well-known methods have not been described in detail in order to avoid obscuring aspects of the present application.

[0043] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood, the following will further describe the present application with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. Figures 1 to 9 The specific embodiments of the present application are described in detail.

[0044] In the current air conditioner product, the indoor unit is generally combined with a bearing assembly of rubber material and a cross-flow fan blade. The bearing is assembled in a special injection molding fixing seat. The cross-flow fan blade is assembled by taking advantage of the flexibility of the rubber material, so as to eliminate the indoor whole machine shaking caused by the rotation of the cross-flow fan blade and reduce the overall noise of the indoor unit.

[0045] However, another disadvantage will also occur. Due to the easy changeability, the bearing assembly is prone to be out of position, and then is out of the fixing seat, which finally leads to the friction between the bearing end face and the cross-flow fan blade end face, thereby generating abnormal noise and affecting the user experience.

[0046] Therefore, the embodiment provides an air conditioner. The air conditioner comprises a base 100, the base 100 comprising an anti-disengagement structure 110; a fan wheel 200, the fan wheel 200 comprising a rotating shaft 210; a bearing assembly 300, the bearing assembly 300 comprising a bearing seat 310 and a bearing body 320 installed on the bearing seat 310 and used for fixing the rotating shaft 210; wherein the bearing body 320 comprises a top face 321 and a side face 322 surrounding the top face 321, at least part of the side face 322 is embedded in the bearing seat 310, and the anti-disengagement structure 110 is used for stopping the top face 321, so as to limit the bearing body 320 from being out of the bearing seat 310.

[0047] Preferably, as shown in FIG. 1, in the existing bearing assembly scheme, the limiting groove prevents the bearing from being out of position in the case of being assembled in place; however, in the actual production process, the bearing body is not completely assembled into the bearing seat, the bearing assembly can still be smoothly assembled into the base in this case, and the bearing assembly is not foolproof, and the installation of the fan wheel is not affected, and the disassembly of the bearing body from the bearing seat is not easy to be found in the production. Figure 9 Figure 1 , 2 ​As shown, the present application limits the bearing body 320 from being pulled out relative to the bearing seat 310 through the anti-pulling-out structure 110 arranged on the base 100 of the air conditioner; when the bearing body 320 is not assembled in place, the anti-pulling-out structure 110 blocks the bearing side surface 322, so that the bearing seat 310 cannot be assembled into the base 100, thereby achieving the fool-proof function; when the air conditioner works, the rotating shaft 210 works, the bearing assembly 300 plays a supporting role, and when the bearing body 320 has the risk of being pulled out, the anti-pulling-out structure 110 is used to block the bearing top surface 321, thereby achieving the limiting function; through the anti-pulling-out structure 110 arranged on the base 100, the anti-pulling-out structure 110 is used to limit the bearing body 320, which not only can achieve the limiting function, but also can play the fool-proof function, thereby preventing the bearing body 320 from being pulled out due to negligence in production, preventing the bearing body 320 from falling off in actual use, ensuring the stability of the bearing body 320 after being installed, and effectively preventing the bearing body 320 from being loosened and deviated.

[0051] In one embodiment of the present application, at least part of the edge of the blocking wall is formed as a curve to avoid the rotating shaft 210.

[0052] Preferably, at least part of the edge of the blocking wall is formed as a curve to avoid the rotating shaft 210, so that the blocking wall can block the bearing top surface 321, thereby achieving the limiting function while ensuring that the rotating shaft 210 can normally work and the air conditioner can normally work.

[0053] In one embodiment of the present application, the anti-pulling-out structure 110 is provided with a heat dissipation hole 111 for heat dissipation of the bearing body 320.

[0054] Preferably, during the working process of the air conditioner, the rotating shaft 210 rotates at high speed in the bearing body 320, which generates a large amount of friction heat, and after the anti-pulling-out structure 110 is added to the base 100, the hardness of the bearing body 320 may not be uniform due to uneven heat dissipation, thereby causing the noise generated by the shaking of the fan blade, and therefore, the heat dissipation hole 111 is arranged on the anti-pulling-out structure 110.Figure 3 As shown, the anti-disengagement structure 110 is provided with a heat dissipation hole 111 for dissipating heat of the bearing body 320, so as to ensure uniform heat dissipation of the bearing body 320.

[0055] In one embodiment of the present application, the heat dissipation hole 111 comprises at least two semi-annular holes arranged around the rotating shaft 210 and spaced apart.

[0056] Preferably, the heat dissipation hole 111 comprises at least two semi-annular holes arranged around the rotating shaft 210 and spaced apart, thereby increasing the heat dissipation of the bearing body 320, improving the working efficiency, prolonging the service life of the bearing body 320, and increasing the safety.

[0057] Further, the bearing body 320 is provided with a bearing heat dissipation hole 111, and the heat dissipation hole 111 of the present application corresponds to the bearing heat dissipation hole 111, so as to further ensure uniform heat dissipation of the bearing, improve the working efficiency, prolong the service life of the bearing body 320, and increase the safety.

[0058] In one embodiment of the present application, the top surface 321 has a semispherical shape protruding from the edge to the center.

[0059] Preferably, the top surface 321 of the bearing body 320 has a semispherical shape protruding from the edge to the center, which can be used for assembling and guiding the bearing assembly 300 into the base 100, facilitating the assembly of the bearing assembly 300, and improving the assembly efficiency.

[0060] Further, as shown, the bearing assembly 300 is provided with an assembly guide angle, which is used for assembling and guiding the bearing assembly 300 into the base 100, facilitating the assembly, and the recommended angle is ≤20°, so as to maximize the effect and improve the efficiency. Figure 4

[0061] In one embodiment of the present application, the bearing seat 310 is provided with a first positioning plane 311, and the left and right sides of the first positioning plane 311 are provided with limiting blocks 312, and the anti-disengagement part 330 is used for connecting the left and right limiting blocks 312; the base 100 comprises a first hole 130; the anti-disengagement part 330 is clamped and matched with the first hole 130.

[0062] Preferably, as shown, the bearing seat 310 is provided with a first positioning plane 311 and a limiting block 312, and the anti-disengagement part 330 is used for connecting the left and right limiting blocks 312; the first hole 130 of the base 100 is clamped and matched with the anti-disengagement part 330, and the anti-disengagement buckle on the bearing seat 310 is matched with the first hole 130 of the base 100 to limit the position, so that the bearing seat 310 can be better fixed on the base 100, and the bearing seat 310 has the ability to resist and prevent the bearing body 320 from deviating along one side. Figures 5-8 Preferably, as shown, the bearing seat 310 is provided with a first positioning plane 311 and a limiting block 312, and the anti-disengagement part 330 is used for connecting the left and right limiting blocks 312; the first hole 130 of the base 100 is clamped and matched with the anti-disengagement part 330, and the anti-disengagement buckle on the bearing seat 310 is matched with the first hole 130 of the base 100 to limit the position, so that the bearing seat 310 can be better fixed on the base 100, and the bearing seat 310 has the ability to resist and prevent the bearing body 320 from deviating along one side.​

[0063] In one embodiment of the present application, the anti-disengagement part 330 is composed of connecting arms 331 connected to the two side limiting blocks 312 and buckles 332 arranged between the two connecting arms 331.

[0064] Preferably, the anti-disengagement part 330 is composed of connecting arms 331 connected to the two side limiting blocks 312 and buckles 332 arranged between the two connecting arms 331. On one hand, no other fastening accessories are needed during assembly, saving cost; on the other hand, the connecting strength of the buckles 332 is great; and on the other hand, the buckles 332 are simple and convenient to connect, allowing quick assembly and disassembly, which can even be done without auxiliary tools.

[0065] In one embodiment of the present application, the rotating shaft 210 has a connecting end 211 facing the bearing body 320, and a second positioning plane 212 is arranged on the connecting end 211; and a second hole 140 is formed in the base 100, and a positioning member 350 is arranged in the second hole 140 and abuts against the second positioning plane 212.

[0066] Preferably, by arranging the second positioning plane 212 on the rotating shaft 210 facing the bearing body 320 and the positioning member 350 in the second hole 140 of the base 100 and abutting against the second positioning plane 212, the assembly efficiency can be improved when assembling the bearing seat 310, the positioning member 350 plays a limiting role, so that the bearing seat 310 has only one degree of freedom in the direction of assembly, which can save manpower and facilitate disassembly and assembly.

[0067] In one embodiment of the present application, the positioning member 350 is arranged on the bearing seat 310, and the positioning member 350 is formed as a rib strip matching the shape of the second hole 140.

[0068] Preferably, by arranging the positioning member 350 on the bearing seat 310 as a rib strip matching the shape of the second hole 140, the bearing seat 310 is prevented from shaking, the assembly efficiency of the base 100 and the bearing seat 310 is greatly improved, and the reliability of the connection between the base 100 and the bearing seat 310 is ensured; in addition, the positioning member 350 has high overall strength and stability, is more convenient to assemble, has a longer service life, and the service life of the air conditioner is longer.

[0069] Further, as shown in FIG. 4, the bearing seat 310 is installed on the base 100 of the air conditioner, the positioning member 350 abuts against the second hole 140, and the bearing seat 310 is placed into the base 100 due to the large chamfer of the positioning member 350 in each contact direction. Figure 6 Figure 7 、 8 ​The positioning member 350 also plays a limiting role after the bearing seat 310 is loaded into the base 100 in the direction of the arrow shown, so that the bearing seat 310 only has one degree of freedom in the loading direction. At this time, the anti-disengagement part 330 on the bearing seat 310 cooperates with the first hole 130 on the base 100 to play a limiting role, so that the only degree of freedom of the bearing seat 310 is also constrained, thereby completing the assembly of the bearing seat 310.

[0070] Furthermore, the application utilizes the simple anti-disengagement structure 110 to achieve the foolproof function while meeting the limiting role. When the bearing body 320 is not assembled in place, the anti-disengagement structure 110 blocks the bearing side surface 322, so that the bearing seat 310 cannot be loaded into the base 100, thereby achieving the foolproof function. When the air conditioner is working, the rotating shaft 210 works, the bearing assembly 300 plays a supporting role, and the bearing body 320 has a risk of disengagement. The anti-disengagement structure 110 is used to block the bearing top surface 321, thereby achieving the limiting role. The anti-disengagement structure 110 can act on more than 50% of the area of the bearing top surface 321, and at the same time forms double limiting with the original limiting groove in the bearing seat 310, so that the risk of disengagement of the bearing is small. When the bearing is not completely loaded into the bearing seat 310, it will directly interfere with the bearing side surface 322, so that the production line can intuitively lock the root cause and immediately adjust the bearing assembly, thereby ensuring the stability of the bearing body after installation and effectively preventing the loosening and deviation of the bearing body. At the same time, the installation is convenient and fast, greatly improves the assembly efficiency, and is suitable for industrial production.
