[0035] Figure 1 is a schematic partial structural diagram of a housing assembly according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 5 The embodiment of the utility model provides a housing assembly, including a housing. The inner wall of the housing 110 has a first routing position 120, a second routing position 130 and a third routing position 140 for the wiring harness 170 to be wound around in sequence, wherein the first routing position 120 is above the third routing position 140, and the second routing position 130 is between the first routing position 120 and the third routing position 140. In addition, a first winding structure is formed on the second routing position 130, and the first winding structure protrudes inward from the inner wall to prompt the wiring harness 170 to be wound into the third routing position 140 from below, and form a return bend section at the second routing position 130.

[0036] In the housing assembly of the embodiment of the utility model, when wiring is performed on the housing 110, the wire harness 170 is wound around the first wiring position 120, and then goes down from the first wiring position 120 to the second wiring position 130, the wire harness 170 is wound around the first winding structure, and then comes out of the first winding structure, and finally winds into the third wiring position 140 from below the third wiring position 140. In other words, the wire harness 170 is first wound downward and then wound upward around the first winding structure, and the wire harness 170 forms a downwardly protruding return bend section at the first winding structure. It can be seen that in the wiring operation, it is only necessary to wrap the wire harness 170 around the first routing position 120, then downward around the second routing position 130 and then upward around the third routing position 140. The wire harness 170 naturally forms a return bend at the second routing position 130. Compared with the wiring operation in the prior art that uses wire clamps and cable ties to fix the wire harness 170, the utility model reduces the process difficulty of fixing the wire harness 170 and reduces the assembly cost.

[0037] Furthermore, in this embodiment, the wiring harness 170 can be fixed only by using the first wiring position 120 , the second wiring position 130 , and the third wiring position 140 . The structure is very simple and the production efficiency is high.

[0038] In some embodiments of the present invention, Figure 1 As shown, the housing assembly further includes a wire harness 170. The wire harness 170 sequentially winds through the first wiring position 120, the second wiring position 130 and the third wiring position 140, and forms a water return bend section at the second wiring position 130.

[0039] In this embodiment, the wire harness 170 is led out from above the first routing position 120, and passes through the first routing position 120 from top to bottom, and then goes downward to reach the second routing position 130. The wire harness 170 passes through the second routing position 130 in a downward and then upward manner, and then continues upward to pass through the third routing position 140 below the third routing position 140. A downwardly protruding return bend section is formed at the second routing position 130. When there is water on the wire harness 170, the water will gather at the return bend section under the influence of its own weight, and when a certain amount of water is gathered, it will drip at the lowest point of the return bend section. Due to the setting of the return bend section, the water on the wire harness 170 will not reach the third routing position 140. When the wire harness 170 is connected to an electrical box, water is prevented from flowing into the electrical box along the wire harness 170, thereby protecting the electrical box.

[0040] In some embodiments of the present invention, Figure 2 and Figure 4As shown, the first winding structure includes a first winding post 131 and a first wire blocking portion 132. The first winding post 131 protrudes inward from the inner wall to facilitate the wiring harness 170 to be wound around the lower side of the first winding post 131. The first wire blocking portion 132 extends downward from the rear end of the first winding post 131 so that the first winding post 131 and the first wire blocking portion 132 form a first hook body that opens downward.

[0041] It can be seen from the above embodiment that after the wire harness 170 has passed through the first routing position 120, it reaches the second routing position 130 in the downward direction and forms a return bend section at the second routing position 130. In this embodiment, when the wire harness 170 reaches the first winding structure of the second routing position 130, the wire harness 170 first passes through the lower side of the first winding post 131. Since the rear end of the first winding post 131 is provided with a first wire blocking portion 132 extending downward, the wire harness 170 will not fall out of the rear end of the first winding post 131, ensuring that the wire harness 170 is fixed very reliably on the second routing position 130. In addition, the first winding structure is a first hook body composed of the first winding post 131 and the first wire blocking portion 132, and the structure is very simple.

[0042] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the housing 110 also has a slope portion 160 located at the lower side of the second wiring position 130 , and a first avoidance opening 161 is defined on the slope portion 160 . The first avoidance opening 161 is located at the front side of the first wire blocking portion 132 and the lower side of the first winding pole 131 .

[0043] In this embodiment, when wiring, the wire harness 170 is firstly passed into the first avoidance opening 161 at one side of the second wiring portion, and then passed out from the other side of the second wiring portion through the first avoidance opening 161. At this time, part of the wire harness 170 is located at the lower side of the first winding portion and the front side of the first wire blocking portion 132, that is, the wire harness 170 has been fixed at the second wiring position 130. The provision of the first avoidance opening 161 makes wiring simpler and more convenient.

[0044] Furthermore, since the lower side of the second routing position 130 has a sloped surface 160, the first avoidance opening 161 is formed on the sloped surface 160, that is, the wire harness 170 passing through the second routing position 130 is supported by the sloped surface. As can be seen from the above embodiment, the wire harness 170 passing through the second routing position 130 continues to move upward into the third routing position 140. The provision of the sloped surface can reduce the weight of the wire harness 170 borne by the third routing position 140, so that the wire harness 170 will not be dragged downward due to gravity, and the wire harness 170 is prevented from being separated from the second routing position 130 and the third routing position 140.

[0045] Furthermore, the provision of the first avoidance opening 161 expands the space below the second wiring position 130 , so that the second wiring position 130 can be wound with more wire harnesses 170 , or the second wiring position 130 can be wound with wire harnesses 170 with larger diameters.

[0046] In some alternative embodiments of this embodiment, the first avoidance opening 161 is located at the front side of the first wire blocking portion 132 .

[0047] In some alternative embodiments of this embodiment, the first avoidance opening 161 is located at the lower side of the first winding pole 131 .

[0048] In some embodiments of the present invention, Figure 3 As shown, a second winding structure is formed on the third wiring position 140 , and the second winding structure defines a winding groove that is open upward, and the winding groove penetrates the housing 110 in the front-to-back direction.

[0049] As can be seen from the above embodiment, after the wire harness 170 passes through the second routing position 130, it reaches the third routing position 140 upwards, and passes through the third routing position 140 from below the third routing position 140. In this embodiment, the wire harness 170 passes through the winding groove from the inner side of the housing 110, and then reaches the outer side of the housing 110. Since the winding groove opens upward, that is, the wire harness 170 passing through the winding groove is placed on the winding groove, which supports the wire harness 170 and prevents the wire harness 170 from falling off easily.

[0050] Furthermore, since the winding groove has an upward opening, it is convenient for the wire harness 170 to pass through the winding groove during the wiring process.

[0051] In some embodiments of the present invention, the bottom end of the first winding post 131 is at the same height as the bottom end of the winding groove.

[0052] It can be seen from the above embodiments that the first winding post 131 is a component of the first winding structure, and the winding groove is a component of the second winding structure. The wire harness 170 is wound around the second winding structure after winding around the first winding structure. In this embodiment, since the bottom end of the first winding post 131 is at the same height as the bottom end of the winding groove, and the wire harness 170 is wound around the lower side of the first winding post 131 and then wound around the second winding structure upward, the wire harness 170 forms a return bend section that first goes downward and then upward at the first winding structure. The structure is simple, and the efficiency of wiring operations is improved.

[0053] In some embodiments of the present invention, the bottom end of the first winding post 131 is lower than the bottom end of the winding groove.

[0054] It can be seen from the above embodiment that the first winding post 131 is a component of the first winding structure, and the winding groove is a component of the second winding structure. The wire harness 170 is wound around the second winding structure after winding around the first winding structure. In this embodiment, since the bottom end of the first winding post 131 is lower than the bottom end of the winding groove, the wire harness 170 is wound around the lower side of the first winding post 131 and then wound around the second winding structure upward, so that the wire harness 170 forms a return bend section that first goes downward and then upward at the first winding structure.

[0055] In some embodiments of the present invention, Figure 1 to Figure 2 , Figures 4 to 5 As shown, a third winding structure is formed at the first wiring position 120, and the third winding structure includes a second winding post 121 and a second wire blocking portion 122. The second winding post 121 protrudes inward from the inner wall. The second wire blocking portion 122 extends rightward from the rear end of the second winding post 121, so that the second winding portion and the second wire blocking portion 122 form a second hook body.

[0056] In the present embodiment, when wiring, the wire harness 170 reaches the first wiring position 120 from above the first wiring position 120, then winds around the right side of the second winding post 121, and extends downward. Since the rear end of the second winding post 121 is provided with a second wire blocking portion 122 extending to the right, the wire harness 170 is located at the front side of the second wire blocking portion 122 when winding around the second winding post 121. The setting of the second wire blocking portion 122 limits and fixes the wire harness 170 wound around the second winding post 121, so that the wire harness 170 on the housing 110 is neat and beautiful. In addition, the third winding structure is a second hook body composed of the second winding post 121 and the second wire blocking portion 122, and the structure is very simple. In some alternative embodiments of the utility model, the second wire blocking portion 122 extends to the left from the rear end of the second winding post 121 to form a second hook body opening to the left. When wiring, the wire harness 170 is located on the left side of the second winding portion and the front side of the second wire blocking portion 122.

[0057] In some alternative embodiments of the present invention, the second wire blocking portion 122 extends leftward and rightward from the rear end of the second winding post 121 to form a second hook body with openings to the left and right. When wiring, the wire harness 170 can be located on the left side of the second winding portion or on the right side of the second winding portion. Of course, part of the wire harness 170 can also be located on the left side of the second winding portion, and the other part can be located on the right side of the second winding portion.

[0058] In some embodiments of the present invention, Figures 1 to 3 As shown, a second avoidance opening 150 is defined on the housing 110 , and the second avoidance opening 150 is located at the front side of the second wire blocking portion 122 .

[0059] In this embodiment, when wiring, if the wire harness is relatively thick and difficult to enter from the opening of the second hook body, the second hook body can be inserted from top to bottom. The second avoidance opening is provided to facilitate the relatively thick wire harness to enter the second hook body from top to bottom, making wiring simpler and more convenient, and the second avoidance opening also provides a larger accommodation space in the second hook body.

[0060] In some embodiments of the present invention, Figure 5 As shown, the housing assembly further includes an anti-pull-off structure. The anti-pull-off structure is disposed inside the housing, above the first wiring position 120, and a wire harness 170 is wound around the anti-pull-off structure to prevent the wire harness 170 from being pulled off upward or downward.

[0061] It can be seen from the above embodiment that the wire harness 170 is wound downward through the first routing position 120 from above the first routing position 120. In this embodiment, the wire harness 170 is wound on the anti-pull-off structure, and then the wire harness 170 is wound downward through the first routing position 120. The anti-pull-off structure prevents the wire harness 170 from being pulled off in the direction of the force when the wire harness 170 is subjected to force, and fixes the wire harness 170.

[0062] In some embodiments of the present invention, Figure 5 As shown, the anti-pull-off structure includes three winding posts, including two third winding posts 181 and a fourth winding post 182. The two third winding posts 181 are arranged in sequence along the width direction of the housing 110, and another winding post is arranged above the two third winding posts 181 and located between the two third winding posts 181.

[0063] In this embodiment, two third winding poles 181 and one fourth winding pole 182 are surrounded by a triangle, that is, when two third winding poles 181 and one fourth winding pole 182 are connected in pairs, the shape formed is a triangle, and the bottom side of the triangle is set horizontally. One end of the wire harness 170 extending from the top of the anti-pull-off structure is first wound around the fourth winding pole 182, then wound downwardly around one of the third winding poles 181, then wound around another third winding pole 181, and finally wound downwardly through the first routing position 120. The anti-pull-off structure surrounding the triangle can better fix the wire harness 170 and prevent the wire harness 170 from being dragged and displaced in the direction of force when subjected to force.

[0064] The embodiment of the utility model further provides an air conditioner, comprising a housing assembly and an evaporator as in any of the above embodiments. The evaporator is arranged inside the housing 110 .

[0065] When the air conditioner is in cooling mode, the surface temperature of the evaporator is lower than the dew point temperature of the indoor air, and the water vapor in the air condenses here when it is cold, forming condensed water. In this embodiment, the wiring harness 170 is fixed to the inner side of the housing 110 through the first wiring position 120, the second wiring position 130 and the third wiring position 140. Since the evaporator is also located on the inner side of the housing 110, that is, the evaporator and the wiring harness 170 are arranged on the same side. Therefore, when the air conditioner is in cooling mode, condensed water will adhere to the wiring harness 170. When the condensed water gathers into large water droplets, the water droplets will flow downward along the wiring harness 170 under the action of gravity.

[0066] Since the wiring harness 170 forms a return bend section at the second wiring position 130 of the housing assembly, when condensed water flows along the wiring harness 170 to the return bend section, it will drip at the lowest point of the return bend section and will not follow the wiring harness 170 to reach the third wiring position 140.

[0067] In some embodiments of the present invention, the air conditioner further includes an electrical box, which is at least located at the lower side of the third wiring position 140 and connected to the wiring harness 170 .

[0068] As can be seen from the above embodiments, condensed water will drip in the water return bend section, and the wire harness 170 first goes around the water return bend section and then goes around the third wiring position 140. In this embodiment, the electrical box is connected to the wire harness 170 that goes around the third wiring position 140, and is located at the lower side of the third wiring position 140. Therefore, condensed water will not enter the electrical box along the wire harness 170, reducing the risk of leakage caused by water ingress into the electrical box.

[0069] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
