Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile air conditioner, concretely relates to a one-way ventilation structure of automobile air conditioner air duct. BACKGROUND

[0002] The automobile air conditioner blows the wind to different positions in the car through the different modes of blowing face, blowing foot and defrosting, and sometimes because of the space limitation in the car, the blowing face and defrosting air duct share an air duct, therefore, the blowing face and defrosting air outlet of the air conditioner are required to be the same, and the same air outlet is required to blow out the wind of different modes, the prior art controls the opening / closing of the air duct opening through the motor driven air door, thereby realizing that the same outlet blows out the wind of different air ducts, but this makes the overall structure of the product more complex, and the production cost is also higher. SUMMARY

[0003] The utility model discloses a one-way ventilation structure of automobile air conditioner air duct to overcome the above-mentioned defects in the prior art.

[0004] A one-way ventilation structure of automobile air conditioner air duct, comprising a windproof sponge and a fixed plate, the windproof sponge is arranged on the fixed plate, the fixed plate is arranged on the inner wall of the air duct one of the automobile air conditioner, and the windproof sponge is arranged on the outer wall of the air duct two ventilation opening.

[0005] Preferably, the windproof sponge is adhered to the fixed plate.

[0006] Preferably, the fixed plate is connected with the inner wall of the air duct one through a plurality of screws.

[0007] Preferably, the screw is provided with two and symmetrically arranged at both ends of the fixed plate.

[0008] Preferably, the windproof sponge is of rectangular structure.

[0009] The utility model discloses the beneficial effects reached are:

[0010] The utility model discloses the windproof sponge to control the opening / closing of the air duct opening instead of the motor driven air door, realizes that the same outlet blows out the wind of different air ducts, thereby simplifying the structure of the product, reducing the weight of the product and reducing the production cost of the product.

[0017] The specific embodiments of the utility model are further explained in detail by the description of the embodiments with reference to the drawings, to help the skilled in the art to have more complete, accurate and deep understanding of the conception and technical scheme of the utility model.

[0018] As Figures 1-5 shown, the utility model provides a kind of one-way ventilation structure of automobile air conditioner air duct, including windproof sponge 3 and fixed plate 4, windproof sponge 3 is rectangular structure, windproof sponge 3 is adhered on fixed plate 4, the fixed plate 4 is located on the inner wall of the first air duct 1 of automobile air conditioner, and windproof sponge 3 is shielded on the outer wall of the ventilation opening of the second air duct 2.

[0019] In addition, the fixed plate 4 is connected with the inner wall of the first air duct 1 by a plurality of screws, the screw is provided with two and symmetrically arranged at both ends of the fixed plate 4, so that the fixed plate 4 is conveniently disassembled from the first air duct 1.

[0020] Specific embodiments and principles:

[0021] The fixed plate 4 on windproof sponge 3 is connected to the first air duct 1 by screw, and one-way ventilation of the second air duct 2 is realized by windproof sponge 3, as follows:

[0022] I. When the first air duct 1 is ventilated, and the second air duct 2 is not ventilated:

[0023] Because of the wind pressure in the first air duct 1, the windproof sponge 3 is tightly attached to the outer wall of the ventilation opening of the second air duct 2, and finally the wind blows out of the outlet;

[0024] II. When the second air duct 2 is ventilated, and the first air duct 1 is not ventilated:

[0025] The wind of the second air duct 2 pushes the windproof sponge 3 away, and finally blows out of the outlet;

[0026] As described above, the opening / closing of the air duct is controlled by the windproof sponge 3 instead of the motor-driven air door, so that the wind from different air ducts is blown out of the same outlet, thereby simplifying the structure of the product, reducing the weight of the product and reducing the production cost of the product.

[0027] The above-mentioned embodiments of the present application do not constitute a limitation on the protection scope of the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
