Description

Technical Field

[0001] This utility model relates to the field of vehicle air conditioning technology, and in particular to a vehicle air conditioning drainage structure. Background Technology

[0002] The drain pipe of a car air conditioner is used to drain the condensate produced when the air conditioner is working. Common structures on the market include drain pipes or drain channels integrated into the base. Compared with separate drain pipes, drain channel structures have advantages such as smaller size and lower cost.

[0003] For example, Chinese utility model patent CN214728049U discloses a base structure and a parking air conditioner. The parking air conditioner includes an outer shell and a base installed on the exterior of the vehicle body, with the outer shell covering the base. A water guide and a drain outlet are provided on the base. The water guide is a herringbone-shaped anti-backflow rib. Multiple anti-backflow ribs are arranged regularly and / or irregularly, forming a passage with the drain outlet within the base. A problem with the prior art is that the drainage channel has poor sealing. During vehicle movement, bumps can cause water droplets to splash up or other foreign objects to fall into the drainage channel, causing electrical short circuits or drainage blockages. Therefore, the prior art needs improvement. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a vehicle air conditioning drainage structure with good sealing performance, windproof and waterproof backflow prevention.

[0005] The technical solution adopted by this utility model to solve the problem is: a vehicle air conditioner drainage structure, including a base and a housing mounted on the base, wherein the base is provided with a drain outlet.

[0006] The base is provided with a water guiding part, which is connected to the drain outlet. The water guiding part has an opening on the upper side, and a top cover is attached to the opening on the upper side of the water guiding part.

[0007] As a further improvement to the above technical solution, the inner wall of the water guide is provided with anti-backflow ribs, which are arranged regularly or irregularly.

[0008] As a further improvement to the above technical solution, the top cover has a U-shaped cross-section, a through groove is provided inside the top cover, and a boss is provided inside the groove. The length and orientation of the boss are consistent with the groove.

[0009] As a further improvement to the above technical solution, the boss is provided with clearance grooves on both sides, the side wall of the water guide is inserted into the clearance groove, and the bottom surface of the boss abuts against the top surface of the anti-backflow rib.

[0010] As a further improvement to the above technical solution, the boss is integrally formed with the top cover.

[0011] The beneficial effects of this utility model are: by setting a sealed top cover on the upper side of the water guide section, water droplets are prevented from splashing up during the drainage process of the water guide section, which could affect the internal wiring and electronic components of the air conditioner. Foreign objects are also prevented from falling into the water guide section and causing drainage blockage. At the same time, anti-backflow ribs are set inside the water guide section to prevent water backflow. This drainage structure has good sealing performance and smooth drainage.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 2 A vehicle air conditioning drainage structure includes a base 1 and a housing mounted on the base 1, wherein the base 1 is provided with a drain outlet 12.

[0023] In a preferred embodiment, the base 1 is provided with a water guiding part 11, which is connected to the drain outlet 12. The water guiding part 11 has an opening on its upper side, and a top cover 2 is attached to the opening on its upper side. The top cover 2 seals the upper side of the water guiding part 11 to prevent water droplets from splashing and damaging electronic components, and to prevent foreign objects from entering and causing drainage blockage.

[0024] In a preferred embodiment, the inner wall of the water guide section 11 is provided with anti-backflow ribs 111, which are arranged regularly or irregularly. When the vehicle air conditioner is working, a negative pressure cavity is formed inside the heat exchanger. The anti-backflow ribs 111, which are set at an angle on the inner wall of the water guide section 11, can not only prevent water from flowing back or in reverse, but also prevent air from flowing back into the heat exchanger cavity from the water guide section, thus affecting the heat exchange effect of the air conditioner.

[0025] Reference Figures 3 to 4 In a preferred embodiment, the top cover 2 has a U-shaped cross-section and a through groove 21 inside. A boss 22 is provided within the groove 21, and the length and orientation of the boss 22 are consistent with the groove 21. The top cover 2 is inverted and placed over the water guide portion 11, with the inner wall of the top cover 2 tightly fitted to the outer wall of the water guide portion 11, providing a good seal.

[0026] The boss 22 has clearance grooves 23 on both sides, and the side wall of the water guiding part 11 is inserted into the clearance grooves 23. The bottom surface of the boss 22 abuts against the top surface of the anti-backflow rib 111. Due to the groove 21, the thickness of the middle part of the top cover 2 is relatively thin. The boss 22 is provided to increase the structural strength of the middle part of the top cover 2, while the anti-backflow rib 111 can also support the boss 22 and the middle part of the top cover 2 while increasing the structural strength of the water guiding part 11.

[0027] In a preferred embodiment, the boss 22 is integrally formed with the top cover 2, thereby increasing the structural strength of the top cover 2.

[0028] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
