Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly relates to a fan installation structure for an air conditioner. Background Art

[0002] A fan is provided in an air conditioner. A commonly used fan installation structure includes a fan, a front installation housing, and a rear installation housing. The front installation housing and the rear installation housing are detachably connected together by a connecting member. An installation cavity is provided between the front installation housing and the rear installation housing. The fan is disposed in the installation cavity. A wire harness is connected to the fan. A wire harness through hole is provided in the right half of the front installation housing, and the wire harness passes through the wire harness through hole. The wire harness is usually connected to the fan by welding. Since the wire harness is directly threaded through the wire harness through hole, during the production and use of the air conditioner, once there is a pull that tightens the wire harness, it is easy to cause the wire harness to fall off at the welding position, affecting the use of the fan and the air conditioner. Summary of the Invention

[0003] The technical problem solved by the present invention is to provide a fan installation structure for an air conditioner, and the fan installation structure can effectively reduce the possibility of the wire harness of the fan falling off.

[0004] The technical solution adopted by the present invention to solve its technical problems is: A fan installation structure for an air conditioner includes a fan, a front installation housing, and a rear installation housing. The front installation housing and the rear installation housing are detachably connected together by a connecting member. An installation cavity is provided between the front installation housing and the rear installation housing. The fan is disposed in the installation cavity. A wire harness is connected to the fan. A wire harness through hole is provided in the right half of the front installation housing. It further includes a first wire clip and a second wire clip. The first wire clip is connected to the lower side of the front installation housing and is located in the right half of the front installation housing. The second wire clip is connected to the right side of the front installation housing or the right side of the rear installation housing. The positions of the wire harness through hole and the second wire clip are both higher than the position of the first wire clip;

[0005] The wire harness passes through the wire harness through hole, the first wire clip, and the second wire clip in sequence.

[0006] Further, the fan is vertically disposed in the installation cavity.

[0007] Further, heat dissipation through holes are respectively provided on the front installation housing and the rear installation housing.

[0008] Further, the first wire clip is a groove-shaped opening structure, and the cross-section of the first wire clip is a C-shaped.

[0009] Further, the second wire clip is connected to the right side of the rear installation housing;

[0010] The second wire clamp has an upper-end opening structure. The second wire clamp includes a connecting cross bar and a vertical bar. One end of the connecting cross bar is connected to the right side of the rear mounting housing, and the other end of the connecting cross bar is connected to one end of the vertical bar. The vertical bar is vertically arranged on the connecting cross bar. Between the lower half of the vertical bar, the connecting cross bar and the rear mounting housing is a wire passing cavity, and between the upper half of the vertical bar and the rear mounting housing is a wire inlet cavity.

[0011] Furthermore, the vertical bar is made of an elastic material. The width of the wire passing cavity is b, and the width of the wire inlet cavity is a, where b > a.

[0012] Furthermore, the width of the wire inlet cavity decreases successively from top to bottom.

[0013] Furthermore, the connection part between the upper half and the lower half of the vertical bar is arc-shaped.

[0014] Furthermore, the connecting piece is a connecting bolt.

[0015] The beneficial effects of the present invention are as follows: By providing the first wire clamp and the second wire clamp, the first wire clamp is connected and arranged on the lower side of the front mounting housing, and the first wire clamp is located in the right half of the front mounting housing. The second wire clamp is connected and arranged on the right side of the front mounting housing or the right side of the rear mounting housing. The positions of the wire harness through hole and the second wire clamp are both higher than the position of the first wire clamp. The wire harness passes through the wire harness through hole, the first wire clamp, and the second wire clamp in sequence. The first wire clamp and the second wire clamp constrain and limit the wire harness, making the wire harness have a certain degree of curvature. When the wire harness is pulled, the tension transmitted to the connection part between the fan and the wire harness is reduced, effectively reducing the possibility of the wire harness of the fan falling off. And, the wire harness is arranged in a relatively loose state, thereby reducing the possibility of the vibration generated when the fan rotates at high speed being transmitted to other components of the air conditioner.

Detailed Embodiments

[0020] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0021] The orientations involved in the following text are based on Figure 1 the orientations of the components in

[0022] As shown in Figure 1 , Figure 2 and Figure 3 , the fan installation structure for an air conditioner according to the present invention includes a fan 1, a front mounting housing 2, and a rear mounting housing 3. The front mounting housing 2 and the rear mounting housing 3 are detachably connected together by a connecting member. An installation cavity is provided between the front mounting housing 2 and the rear mounting housing 3. The fan 1 is disposed in the installation cavity. A wire harness 11 is connected to the fan 1. A wire harness through hole 21 is provided in the right half of the front mounting housing 2. The structure further includes a first wire clip 4 and a second wire clip 5. The first wire clip 4 is connected to the lower side of the front mounting housing 2 and is located in the right half of the front mounting housing 2. The second wire clip 5 is connected to the right side of the front mounting housing 2 or the right side of the rear mounting housing 3. The positions of the wire harness through hole 21 and the second wire clip 5 are both higher than the position of the first wire clip 4;

[0023] The wire harness 11 passes through the wire harness through hole 21, the first wire clip 4, and the second wire clip 5 in sequence.

[0024] The wire harness 11 has a certain flexibility. The first wire clip 4 and the second wire clip 5 constrain and limit the wire harness 11, so that the wire harness 11 has a certain degree of curvature. When the wire harness 11 is pulled, the tension transmitted to the connection between the fan 1 and the wire harness 11 is reduced, effectively reducing the possibility of the wire harness 11 of the fan 1 falling off; and, the wire harness 11 is arranged in a relatively loose state, thereby reducing the possibility of the vibration generated when the fan 1 rotates at a high speed being transmitted to other components of the air conditioner.

[0025] Specifically, in order to improve the stability of the installation of the fan 1, the fan 1 is vertically disposed in the installation cavity.

[0026] When the fan 1 operates, it will inevitably generate a certain amount of heat. In order to improve the heat dissipation effect when the fan 1 operates, heat dissipation through holes are respectively provided on the front mounting housing 2 and the rear mounting housing 3.

[0027] The functions of the first wire clip 4 and the second wire clip 5 are to constrain and limit the wire harness 11. In order to improve the use effect of the first wire clip 4, as shown in Figure 1 , Figure 2 again, the first wire clip 4 is a groove-shaped opening structure. The cross-section of the first wire clip 4 is a U-shaped, and the opening of the first wire clip 4 faces the fan 1. The groove part of the first wire clip 4 is the first wire clip wire passing cavity, and the wire harness 11 passes through the first wire clip wire passing cavity.

[0028] Again, as shown in Figure 1 , Figure 2 and Figure 3As shown, the second wire clip 5 is connected to the right side of the rear mounting housing 3. The second wire clip 5 has an upper opening structure. The second wire clip 5 includes a connecting cross bar 51 and a vertical bar 52. One end of the connecting cross bar 51 is connected to the right side of the rear mounting housing 3, and the other end of the connecting cross bar 51 is connected to one end of the vertical bar 52. And the vertical bar 52 is vertically arranged on the connecting cross bar 51. A wire passing cavity 53 is formed between the lower half of the vertical bar 52, the connecting cross bar 51 and the rear mounting housing 3. An incoming wire cavity 54 is formed between the upper half of the vertical bar 52 and the rear mounting housing 3. The wire harness 11 is arranged through the wire passing cavity 53. The wire harness 11 is snapped into the wire passing cavity 53 through the incoming wire cavity 54. In order to reduce the possibility of the wire harness 11 coming out of the wire passing cavity 53, the vertical bar 52 is made of an elastic material. The width of the wire passing cavity 53 is b, that is, the distance between the lower half of the vertical bar 52 and the rear mounting housing 3. The width of the incoming wire cavity 54 is a, that is, the distance between the upper half of the vertical bar 52 and the rear mounting housing 3. b > a. Specifically, the value of a is less than the width of the wire harness 11, and the value of b is slightly greater than the width of the wire harness 11. Since the vertical bar 52 has a certain elasticity, it does not prevent the wire harness 11 from being snapped into the wire passing cavity 53 through the incoming wire cavity 54.

[0029] To make it more convenient for the wire harness 11 to be snapped into the wire passing cavity 53 through the incoming wire cavity 54, for another example Figure 3 As shown, the width of the incoming wire cavity 54 decreases sequentially from top to bottom. Further, the connection part between the upper half of the vertical bar 52 and the lower half of the vertical bar 52 is arc-shaped. Through the arc transition connection, it makes it easier for the wire harness 11 to be snapped into the wire passing cavity 53 through the incoming wire cavity 54, and also reduces the possibility of the vertical bar 52 damaging the wire harness 11.

[0030] To facilitate the connection between the front mounting housing 2 and the rear mounting housing 3 and ensure the connection stability, the connecting piece is preferably a connecting bolt.
