Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a fan blade structure for an air conditioner and an air conditioner. Background Technology

[0002] Air conditioner indoor units come in two types: wall-mounted and floor-standing. Floor-standing units, also known as air conditioner cabinets, can regulate the temperature of large spaces, such as living rooms, commercial spaces, and industrial spaces.

[0003] To elaborate further, the air conditioner cabinet unit has axial fan blades installed at the air outlet on the panel. The rotation of these axial fan blades is driven by a motor to deliver airflow to the indoor environment.

[0004] However, the relevant technology has at least one of the following problems: the thickness of traditional screw-tightening fan blades is relatively large, which results in a small space for disassembly and assembly between the fan blade motor shaft and the fan blade during the process of fixing the fan blade motor shaft to the fan blade, which easily leads to operational interference and increases the difficulty of operation. Utility Model Content

[0005] The technical problem solved by this utility model is that the thickness of traditional screw-tightening fan blades is relatively large, which results in a small space for disassembly and assembly between the fan blade and the motor shaft during the process of fixing the fan blade and the motor shaft to the fan blade. This can easily lead to operational interference and increase the difficulty of operation.

[0006] To solve the above problems, this utility model provides a blade structure for an air conditioner. The blade structure includes a hub and a blade section. The blade section is disposed on the circumferential surface of the hub. One end of the hub is provided with a clearance part, and the hub is provided with a fastening structure for connecting the fan motor shaft of the air conditioner at the position corresponding to the clearance part.

[0007] Compared to existing technologies, the technical effects achieved by this solution are as follows: Specifically, by providing a clearance portion on the hub, the operator can easily install the fan motor shaft onto the fan blade structure, reducing the difficulty of disassembling and assembling the fan motor shaft. Compared to fan blade structures without clearance portions, the length of the fan motor shaft adapted to the fan blade structure is shortened, which improves the stability of driving the fan blade structure's rotation to a certain extent. Considering the application of the fan blade structure to cabinet air conditioners, the width dimension of the cabinet used to install the fan blade structure is reduced, thereby achieving a compact fit between the various components installed inside the cabinet and improving the utilization rate of the cabinet's internal space.

[0008] In one embodiment of this utility model, a mating hole is provided on one side of the fastening structure, which is used to connect the fan motor shaft through a connector; wherein, along the extension direction of the mating hole, the clearance portion exposes the mating hole.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: Specifically, the operator can connect the connector into the mating hole by matching the position of the mating hole and the clearance part, so as to achieve the fastening effect of the fan motor shaft, thereby reducing the difficulty of disassembling and assembling the fan motor shaft.

[0010] In one embodiment of this utility model, the end of the wheel hub with the avoidance part is defined as the first end, and the other end opposite to the first end is defined as the second end; the avoidance part includes a relief groove, which is recessed from the first end to the second end.

[0011] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: For example, by setting a clearance groove, the distance from the edge of the first end to the protrusion of the second end is greater than the distance from the middle part to the protrusion of the second end, that is, the structural feature of being low in the middle and high around the edges, so that after the wind turbine structure is thinned, the wind turbine motor shaft can smoothly complete the cooperation with the fastening structure. In addition, by retaining the structure at the edge position of the first end, the structural strength of the wind turbine structure is improved.

[0012] In one embodiment of this utility model, multiple reinforcing structures are formed at the edge of the first end of the relief groove; the multiple reinforcing structures are arranged at intervals around the axis of the hub.

[0013] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: Specifically, by forming multiple mutually spaced reinforcing structures at the edge position of the first end, the structural strength of the wind turbine structure is improved.

[0014] In one embodiment of this utility model, the reinforcing structure is at least one of the following structures: reinforcing corner, reinforcing rib, and reinforcing rib.

[0015] In one embodiment of this utility model, the fan blade includes a first connecting part and a second connecting part that are connected to each other; the first connecting part is connected to the circumferential surface, and the second connecting part is connected to the outer surface of the reinforcing structure away from the axis.

[0016] Compared with existing technologies, the technical effect achieved by adopting this technical solution is as follows: by setting the connection between the blade and the reinforcing structure, the structural strength of the blade is improved by utilizing the reinforcing angle.

[0017] In one embodiment of this invention, any one of the plurality of reinforcing angles extends toward a direction close to the axis.

[0018] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by extending the reinforcing structure towards the direction closer to the axis, the structural strength of the wind turbine structure is improved to a certain extent, making up for the weakening of structural strength caused by thinning the wind turbine structure.

[0019] In one embodiment of this utility model, the fan blade includes multiple blades, and the multiple blades are matched with multiple reinforcing angles.

[0020] In one embodiment of this utility model, the number of reinforcing angles is n, where 3 ≤ n ≤ 5.

[0021] In one embodiment of this utility model, the fastening structure includes a bushing portion disposed in the clearance portion; the bushing portion is provided with an installation space for mounting the fan motor shaft, and the installation space communicates with the mating hole.

[0022] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: Specifically, by thinning the blade structure and combining it with the fastening structure being set on the avoidance part, the interference from the blade part is reduced during the actual adjustment of the connecting parts, and the efficiency of the adjusting connecting parts for disassembling and assembling the blade motor shaft is further improved.

[0023] On the other hand, this utility model also provides an air conditioner, including: a blade structure as in any of the above examples; wherein the air conditioner is a cabinet air conditioner.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: it can achieve the technical effects corresponding to any of the above examples, which will not be elaborated here.

[0025] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0026] (1) Specifically, by setting a clearance part on the hub, the operator can smoothly install the fan motor shaft onto the fan blade structure with the help of the clearance part, reducing the difficulty of disassembling and assembling the fan motor shaft. Compared with the fan blade structure without a clearance part, the length of the fan motor shaft adapted to the fan blade structure is shortened, which improves the stability of driving the fan blade structure to rotate to a certain extent. Combined with the application scenario of the fan blade structure to cabinet air conditioners, the size of the cabinet used to install the fan blade structure in the width direction is reduced, thereby realizing the compact fit between the various components installed in the cabinet and improving the utilization rate of the internal space of the cabinet;

[0027] (2) By extending the reinforcing structure toward the direction closer to the axis, the structural strength of the wind turbine structure is improved to a certain extent, which makes up for the weakening of the structural strength caused by the thinning of the wind turbine structure.

[0028] (3) By forming multiple mutually spaced reinforcing structures at the edge of the first end, the structural strength of the wind turbine structure is improved. Attached Figure Description

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0039] See Figure 3 This is a schematic diagram of the fan blade structure 10 for an air conditioner 100 provided in an embodiment of this utility model. Specifically, in conjunction with... Figures 1-6The fan blade structure 10 includes, for example, a hub 11 and a fan blade section 12. The fan blade section 12 is disposed on the circumferential surface 111 of the hub 11. One end of the hub 11 is provided with a clearance section 13, and the hub 11 is provided with a fastening structure 14 for connecting the fan blade motor shaft 31 of the air conditioner 100 at the position corresponding to the clearance section 13.

[0040] Specifically, by providing a clearance part 13 on the hub 11, the operator can smoothly install the fan motor shaft 31 onto the fan blade structure 10 using this clearance part 13, reducing the difficulty of disassembling and assembling the fan motor shaft 31. Compared to the fan blade structure 10 without the clearance part 13, the length of the fan motor shaft 31 adapted to the fan blade structure 10 is shortened, which improves the stability of driving the fan blade structure 10 to rotate to a certain extent. Considering the application scenario of the fan blade structure 10 in cabinet air conditioners, the width dimension of the cabinet used to install the fan blade structure 10 is reduced, thereby achieving a compact fit between the various components installed in the cabinet and improving the utilization rate of the cabinet's internal space.

[0041] Preferably, one side of the fastening structure 14 is provided with a mating hole for connecting the fan motor shaft 31 via the connector 142; wherein, along the extending direction of the mating hole, the clearance portion 13 exposes the mating hole. Specifically, the operator adapts the position of the mating hole and the clearance portion 13 to facilitate the connection of the connector 142 into the mating hole, thereby achieving the fastening effect on the fan motor shaft 31 and reducing the difficulty of disassembling and assembling the fan motor shaft 31.

[0042] Preferably, the end of the hub 11 with the relief portion 13 is defined as the first end 15, and the other end opposite to the first end 15 is defined as the second end 16; the relief portion 13 includes a relief groove 131, which is recessed from the first end 15 toward the second end 16.

[0043] For example, by providing a clearance groove 131, the distance from the edge of the first end 15 to the protrusion of the second end 16 is greater than the distance from the middle part to the protrusion of the second end 16, that is, the structural feature of being low in the middle and high around the edges, so that after the fan blade structure 10 is thinned, the fan blade motor shaft 31 can smoothly complete the cooperation with the fastening structure 14. In addition, by retaining the structure at the edge of the first end 15, the structural strength of the fan blade structure 10 is improved.

[0044] Preferably, the clearance groove 131 forms a plurality of reinforcing structures 132 at the edge of the first end 15; the plurality of reinforcing structures 132 are arranged at intervals around the axis 101 of the hub 11. Specifically, by forming a plurality of mutually spaced reinforcing structures 132 at the edge of the first end 15, the structural strength of the wind turbine structure 10 is improved, and by making the adjacent reinforcing structures 132 spaced apart, the material used in the production of the wind turbine structure 10 is saved, and the cost is reduced.

[0045] Preferably, the fan blade 12 includes a first connecting portion 121 and a second connecting portion 122 that are connected to each other; the first connecting portion 121 is connected to the circumferential surface 111, and the second connecting portion 122 is connected to the outer surface of the reinforcing structure 132 away from the axis 101. By providing the connection between the fan blade 12 and the reinforcing structure 132, the structural strength of the fan blade 12 is improved by utilizing the reinforcing structure 132.

[0046] Preferably, any one of the plurality of reinforcing structures 132 extends toward the axis 101.

[0047] Furthermore, the blade section 12 includes multiple blades, which are fitted with multiple reinforcing structures 132.

[0048] Furthermore, the number of reinforcing structures 132 is n, where 3 ≤ n ≤ 5. By extending the reinforcing structures 132 toward the axis 101, the structural strength of the wind turbine structure 10 is improved to a certain extent, compensating for the weakening of structural strength caused by the thinning of the wind turbine structure 10. In addition, since the reinforcing structures 132 extend toward the axis 101, the reinforcing structures 132 are prevented from protruding from the circumferential surface 111 of the hub 11, thus avoiding an increase in the space occupied by the wind turbine structure 10 in the housing.

[0049] Preferably, the fastening structure 14 includes a bushing portion 141 disposed on the clearance portion 13; the bushing portion 141 is provided with a mounting space 143 for mounting the fan motor shaft 31, and the mounting space 143 communicates with the mating hole; wherein, the fan motor shaft 31 disposed in the mounting space 143 is fastened or loosened by adjusting the connecting member 142. Specifically, after the fan blade structure 10 is thinned, combined with the fact that the fastening structure 14 is disposed on the clearance portion 13, the interference from the fan blade portion 12 is reduced during the actual adjustment of the connecting member 142, and the efficiency of adjusting the connecting member 142 to install and remove the fan motor shaft 31 is further improved.

[0050] On the other hand, see 1- Figure 2This utility model embodiment also provides an air conditioner 100. Specifically, the air conditioner 100 includes, for example, the fan blade structure 10 mentioned in the above embodiments; wherein, the air conditioner 100 is a cabinet air conditioner. Correspondingly, in this embodiment, the technical effects corresponding to any of the technical solutions in the above embodiments can be achieved, which will not be repeated here.

[0051] Combination Figure 2 In a specific example, the cabinet air conditioner includes a cabinet 20, a protective cover 40, a locking element 50, and a fan motor structure 30. The cabinet 20 has a mounting groove 21 for installing the fan motor structure 10. The protective cover 40 covers the cabinet 20 at the position corresponding to the mounting groove 21. Specifically, the protective cover 40 has a motor fixing groove 41 for installing the fan motor structure 30 on the side away from the cabinet 20, and the motor fixing groove 41 has a connecting hole for the fan motor shaft 31 of the fan motor structure 30 to extend out.

[0052] Furthermore, the locking element 50 is located on the side of the protective cover 40 away from the cabinet 20, and is used to cover the position of the protective cover 40 where the motor fixing groove 41 is located. Specifically, the locking element 50 is provided with a limiting groove 51. In contrast, the fan motor structure 30 includes a fan motor body 32 that drives the fan motor shaft 31 to rotate, and a limiting protrusion 33 that cooperates with the limiting groove 51 is provided at the tail of the fan motor body 32.

[0053] Therefore, after the locking member 50 is installed onto the protective cover 40, the engagement between the limiting protrusion 33 and the limiting slot 51 effectively prevents the fan motor structure 30 from rotating unexpectedly while driving the fan structure 10 to rotate. For example, the locking member 50 and the protective cover 40 are engaged by a snap-fit ​​mechanism.

[0054] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
