Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] In current air conditioning products, indoor units generally use rubber bearing assemblies with crossflow blades, and the bearings are assembled in special injection molding fixing seats. The crossflow blades are assembled using the good flexibility of rubber materials to eliminate the shaking of the entire indoor unit caused by the rotation of the crossflow blades and reduce the overall noise of the indoor unit.

[0003] However, this will also lead to another disadvantage: due to the volatile nature of the bearing assembly, the bearing may not be properly assembled and may fall out of the fixed seat, which will eventually cause friction between the end face of the bearing and the end face of the crossflow fan blade, thereby generating abnormal noise and affecting the user experience. Summary of the invention

[0004] Therefore, the present invention provides an air conditioner, which provides an anti-slip installation scheme for the bearing assembly on the air conditioner base, and uses structural features to achieve limiting, so that the bearing body is not easy to fall off during actual use, ensuring the stability of the bearing body after installation, effectively preventing the bearing body from loosening and deviating, and increasing the safety factor.

[0005] In order to solve the above problems, the present invention provides an air conditioner, which includes: a base, the base includes an anti-slip structure; a wind wheel, the wind wheel includes a rotating shaft; a bearing assembly, the bearing assembly includes a bearing seat, and a bearing body installed on the bearing seat and used to fix the rotating shaft; wherein the bearing body includes a top surface and a side surface surrounding the top surface, at least a portion of the side surface is embedded in the bearing seat, and the anti-slip structure is used to stop the top surface to limit the bearing body from slipping out relative to the bearing seat.

[0006] Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: in the existing bearing assembly scheme, when the bearing is assembled in place, the limiting groove prevents the bearing from falling out; but in the actual production process, the bearing body may not be completely installed in the bearing seat. In this case, the bearing assembly can still be smoothly installed in the base without affecting the installation of the wind wheel, and it is not easy to find that the assembly is not in place during production; while the present invention sets an anti-slip structure on the base of the air conditioner to limit the bearing body from falling out relative to the bearing seat; when the bearing body is not assembled in place, the anti-slip structure blocks the top surface of the bearing, so that the bearing seat cannot be installed in the base, thereby achieving foolproofing; when the air conditioner is working, the rotating shaft works, the bearing assembly plays a supporting role, and when the bearing body is at risk of falling out, the anti-slip structure is used to block the top surface of the bearing, thereby achieving limiting; the present invention sets an anti-slip structure on the base, utilizing the characteristics of the anti-slip structure, not only can achieve limiting, but also can play a foolproofing role, avoid the bearing body from falling out due to production negligence, thereby preventing the bearing body from falling off during actual use, ensuring the stability of the bearing body after installation, and effectively preventing the bearing body from loosening and deviating.

[0007] In one technical solution of the present invention, the base is provided with a mounting hole surrounding at least a portion of the periphery of the top surface, and the anti-slip structure is formed as a retaining wall extending from at least a portion of the edge of the mounting hole to shield the top surface.

[0009] In a technical solution of the present invention, at least a portion of the edge of the retaining wall is formed into a curve to avoid the rotating shaft.

[0010] Compared with the prior art, the technical effect achieved by adopting this technical solution is that at least part of the edge of the retaining wall is formed into a curve to avoid the rotating shaft, so that the retaining wall can block the top surface of the bearing, achieve limiting while ensuring that the rotating shaft can operate normally and the air conditioner can work normally.

[0011] In a technical solution of the present invention, the anti-slip structure is provided with heat dissipation holes for dissipating heat from the bearing body.

[0012] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: during the operation of the air conditioner, the shaft rotates at high speed in the bearing body, which will generate a large amount of friction heat. After the base is newly provided with an anti-slip structure, the uneven heat dissipation may lead to inconsistent overall hardness of the bearing, causing the fan blades to shake and produce noise. Therefore, it is necessary to provide heat dissipation holes on the anti-slip structure for the bearing body to dissipate heat, so as to ensure uniform heat dissipation of the bearing body.

[0013] In a technical solution of the present invention, the heat dissipation hole includes at least two semi-annular holes which are arranged around the rotating shaft and at intervals.

[0019] In a technical solution of the present invention, it also includes: the anti-slip portion is composed of connecting arms connected to the limiting blocks on both sides, and a buckle arranged between the connecting arms on both sides.

[0020] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the anti-detachment part is composed of connecting arms connected to the limit blocks on both sides, and a buckle arranged between the connecting arms on both sides. On the one hand, the buckle connection does not require other locking accessories during assembly, saving costs; at the same time, the connection strength of the buckle is high; on the other hand, the buckle connection is simple and convenient, and can achieve quick assembly and disassembly, and the disassembly process may not even require auxiliary tools.

[0021] In a technical solution of the present invention, the bearing seat has a connecting end facing the rotating shaft, and a second positioning plane is arranged on the connecting end; a second hole is opened on the base, and a positioning piece which is adapted to the second hole and abuts against the second positioning plane is arranged in the second hole.

DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with 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.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following Figures 1 to 9 The specific embodiments of the present invention are described in detail.

[0044] In current air conditioning products, indoor units generally use rubber bearing assemblies in conjunction with crossflow blades, and the bearings are assembled in special injection molding fixtures. The crossflow blades are assembled using the high flexibility of rubber materials to eliminate the vibration of the entire indoor unit caused by the rotation of the crossflow blades and reduce the overall noise of the indoor unit.

[0045] However, this will also lead to another disadvantage: due to its changeable nature, the bearing may not be properly assembled and may fall out of the fixed seat, which will eventually cause friction between the end face of the bearing and the end face of the crossflow fan blade, thereby generating abnormal noise and affecting the user experience.

[0046] Therefore, the present embodiment provides an air conditioner, which includes: a base 100, the base 100 includes an anti-slip structure 110; a wind wheel 200, the wind wheel 200 includes a rotating shaft 210; a bearing assembly 300, the bearing assembly 300 includes a bearing seat 310, and a bearing body 320 installed on the bearing seat 310 and used to fix the rotating shaft 210; wherein the bearing body 320 includes a top surface 321 and a side surface 322 surrounding the top surface 321, at least a portion of the side surface 322 is embedded in the bearing seat 310, and the anti-slip structure 110 is used to stop the top surface 321 to limit the bearing body 320 from slipping out relative to the bearing seat 310.

[0047] Preferably, Fig. 9 As shown in the figure, in the existing bearing assembly scheme, when the bearing is assembled in place, the limit groove prevents the bearing from falling out; however, in the actual production process, the bearing body may not be completely installed in the bearing seat. In this case, the bearing assembly can still be smoothly installed in the base, which is not foolproof and does not affect the installation of the wind wheel. In addition, it is not easy to find that the assembly is not in place during production; Figure 1 , 2As shown, the present invention limits the bearing body 320 from coming out relative to the bearing seat 310 by means of an anti-slip structure 110 provided on the base 100 of the air conditioner; when the bearing body 320 is not assembled in place, the anti-slip structure 110 blocks the bearing side surface 322, so that the bearing seat 310 cannot be installed into the base 100, thereby achieving foolproofing; when the air conditioner is working, the rotating shaft 210 works, the bearing assembly 300 plays a supporting role, and when the bearing body 320 is at risk of coming out, the anti-slip structure 110 is used to block the bearing top surface 321, thereby achieving position limiting; the present invention uses the anti-slip structure 110 provided on the base 100 and utilizes the characteristics of the anti-slip structure 110 to not only achieve position limiting, but also play a foolproofing role, thereby avoiding the bearing body 320 from coming out due to production negligence, thereby preventing the bearing body 320 from falling off during actual use, ensuring the stability of the bearing body 320 after installation, and effectively preventing the bearing body 320 from loosening and deviating.

[0048] In one embodiment of the present invention, the base 100 is provided with a mounting hole 120 surrounding at least a portion of the periphery of the top surface 321 , and the anti-slip structure 110 is formed as a retaining wall extending from at least a portion of the edge of the mounting hole 120 to cover the top surface 321 .

[0049] Preferably, the anti-slip structure 110 is directly arranged on the base 100, and there is no need to replace the entire base 100. An integrated mold can be used in the production process, which reduces production costs, improves economic benefits, and is suitable for industrial production. At the same time, the anti-slip structure 110 is not easy to be damaged, is easy to assemble, and can improve work efficiency.

[0050] Furthermore, the anti-slip structure 110 can act on more than 50% of the area of ​​the bearing top surface 321 at most, and the anti-mistake effect is intuitive. The anti-slip structure 110 interferes with the outer side of the bearing body 320, and there is no risk of missed inspection during production.

[0051] In one embodiment of the present invention, at least a portion of the edge of the retaining wall is formed into a curve to avoid the rotating shaft 210 .

[0052] Preferably, at least part of the edge of the retaining wall is formed into a curve to avoid the rotating shaft 210, so that the retaining wall can block the top surface 321 of the bearing, and at the same time, ensure that the rotating shaft 210 can operate normally and the air conditioner can work normally.

[0053] In one embodiment of the present invention, the anti-slip structure 110 is provided with heat dissipation holes 111 for dissipating heat from the bearing body 320 .

[0054] Preferably, during the operation of the air conditioner, the rotating shaft 210 rotates at a high speed in the bearing body 320, which will generate a large amount of friction heat. After the anti-slip structure 110 is added to the base 100, the overall hardness of the bearing may be inconsistent due to uneven heat dissipation, which may cause the fan blades to vibrate and generate noise. Therefore, if Figure 3 As shown, it is necessary to provide heat dissipation holes 111 on the anti-slip structure 110 for heat dissipation of the bearing body 320 , so as to ensure uniform heat dissipation of the bearing body 320 .

[0055] In one embodiment of the present invention, the heat dissipation hole 111 includes at least two semi-annular holes that are arranged around the rotation axis 210 and at intervals.

[0056] Preferably, the heat dissipation hole 111 is formed by at least two semi-annular holes which are arranged around the rotating shaft 210 and at intervals, thereby increasing the heat dissipation of the bearing body 320, improving work efficiency, increasing the service life of the bearing body 320, and increasing safety.

[0057] Furthermore, the bearing body 320 is currently provided with a bearing heat dissipation hole 111, and the heat dissipation hole 111 provided in the present invention corresponds to the bearing heat dissipation hole 111, thereby further ensuring uniform heat dissipation of the bearing, improving work efficiency, increasing the service life of the bearing body 320, and increasing safety.

[0058] In one embodiment of the present invention, the top surface 321 has a hemispherical shape that bulges from the edge toward the center.

[0059] Preferably, the top surface 321 of the bearing body 320 has a hemispherical shape protruding from the edge to the center, which can be used in the process of installing the bearing assembly 300 into the base 100, serving as an assembly guide, facilitating the assembly of the bearing assembly 300 and improving assembly efficiency.

[0060] Further, such as Figure 4 As shown, the bearing assembly guide angle acts on the process of installing the bearing assembly 300 into the base 100, and serves as an assembly guide to facilitate assembly. It is recommended that the angle be ≤20° to achieve the maximum effect and improve efficiency.

[0061] In one embodiment of the present invention, the bearing seat 310 is provided with a first positioning plane 311, and limit blocks 312 are provided on the left and right sides of the first positioning plane 311. The anti-slip portion 330 is used to connect the limit blocks 312 on the left and right sides; the base 100 includes a first hole 130; the anti-slip portion 330 is snap-fitted with the first hole 130.

[0062] Preferably, Figure 5-8 As shown, the bearing seat 310 is provided with a first positioning plane 311 and a limit block 312, and the anti-slip portion 330 is used to connect the limit blocks 312 on the left and right sides; the first hole 130 of the base 100 is snap-fitted with the anti-slip portion 330, and the anti-slip buckle on the bearing seat 310 cooperates with the first hole 130 of the base 100 to play a limiting role, so that the bearing seat 310 can be better fixed on the base 100, and can enable the bearing seat 310 to have the ability to resist and prevent the bearing body 320 from deviating along one side.

[0063] In one embodiment of the present invention, the anti-slip portion 330 is further comprised of a connecting arm 331 connected to the limiting blocks 312 on both sides, and a buckle 332 arranged between the connecting arms 331 on both sides.

[0064] Preferably, the anti-detachment part 330 is composed of a connecting arm 331 connected to the limit blocks 312 on both sides, and a buckle 332 arranged between the connecting arms 331 on both sides. On the one hand, the connection with the buckle 332 does not require other locking accessories during assembly, saving costs; at the same time, the connection strength of the buckle 332 is large; on the other hand, the connection of the buckle 332 is simple and convenient, and can achieve quick assembly and disassembly, and the disassembly process may not even require auxiliary tools.

[0065] In one embodiment of the present invention, 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; a second hole 140 is opened on the base 100, and a positioning member 350 is arranged in the second hole 140 which is adapted thereto and abuts against the second positioning plane 212.

[0066] Preferably, by providing a second positioning plane 212 facing the bearing body 320 on the rotating shaft 210; and providing a second hole 140 on the base 100 and a positioning member 350 abutting against the second hole 140, 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 installation direction, which can save manpower and facilitate disassembly and assembly.

[0067] In one embodiment of the present invention, the positioning member 350 is disposed on the bearing seat 310 , and the positioning member 350 forms a rib that matches the shape of the second hole 140 .

[0068] Preferably, by providing the positioning member 350 on the bearing seat 310 with a rib that matches the shape of the second hole 140, the bearing seat 310 is prevented from shaking, which greatly improves the assembly efficiency of the base 100 and the bearing seat 310 and ensures the reliability of the connection between the base 100 and the bearing seat 310; furthermore, the positioning member 350 increases its overall strength and stability, makes assembly more convenient, and extends its service life, thereby extending the service life of the air conditioner.

[0069] Further, such as Figure 6 As shown, the bearing seat 310 is installed on the base 100 of the air conditioner, and the positioning member 350 first contacts the second hole 140. Since the positioning member 350 has a large chamfer in each contact direction, it is easy to put the bearing seat 310 in; the bearing seat 310 is Figure 7 , 8After the base 100 is installed in the direction of the arrow shown, the positioning member 350 will play a limiting role, so that the bearing seat 310 has only one degree of freedom in the installation direction. At this time, the anti-slip portion 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 remaining degree of freedom of the bearing seat 310 is also constrained, thereby completing the assembly of the bearing seat 310.

[0070] Furthermore, the present application utilizes a simple anti-slip structure 110 to achieve foolproofing while satisfying the limiting function. When the bearing body 320 is not assembled in place, the anti-slip structure 110 blocks the bearing side 322, so that the bearing seat 310 cannot be installed in the base 100, thereby achieving foolproofing; when the air conditioner is working, the shaft 210 works, and the bearing assembly 300 plays a supporting role. When the bearing body 320 is at risk of slipping out, the anti-slip structure 110 is used to block the bearing top surface 321, thereby achieving limiting; and the anti-slip structure 110 can act on more than 50% of the area of ​​the bearing top surface 321 at most, and at the same time form a double limit with the original limiting groove in the bearing seat 310, so that the risk of the bearing slipping out is small; when the bearing is not fully installed in the bearing seat 310, it will directly interfere with the bearing side 322, and the production line can intuitively lock the root cause and immediately adjust the bearing assembly to ensure the stability of the bearing body after installation, and effectively prevent the loosening and deviation of the bearing body; at the same time, the installation is convenient and quick, which greatly improves the assembly efficiency and is suitable for industrial production.
