Description

Technical Field

[0001] The utility model belongs to the technical field of louver air vents, and in particular relates to a wind and rainproof single-layer louver air vent. Background Art

[0002] Air conditioning systems are usually equipped with louvered fresh air vents and exhaust vents on the exterior walls. Common louver vents include single-layer louver vents, double-layer louver vents, side wall grille vents, and slit grille vents. Single-layer louver vents are often used for return air vents. Although the current single-layer louver vents have a certain wind and rain protection effect, they are only limited to smaller wind and rain environments. Once the louver vents are under the attack of typhoons, rainstorms or heavy rain, the air conditioning vents on the exterior walls, especially the fresh air vents, are prone to leaking rain; in addition, fine cracks are prone to appear at the bottom of the single-layer louver vents, causing rainwater to accumulate. If a large amount of rainwater enters the air duct and air conditioning unit from the bottom of the louver vents, it will have an adverse effect on the performance and safety of the air conditioning system.

[0003] The rainproof function of the single-layer louver air vent in the prior art is achieved by setting an isolation net behind the louver air vent. For example, CN219199448U discloses a rainproof and dustproof louver air vent, including a device main body, a fan blade frame is arranged inside the device main body, and fan blades are arranged inside the fan blade frame, the fan blade frame is fixedly connected with a mounting frame, a third threaded hole is arranged inside the side wall of the mounting frame, a dustproof net is connected to the right side wall of the mounting frame, a fixing frame is arranged on the right side of the mounting frame, and a second threaded hole is arranged inside the fixing frame, a second bolt is threadedly connected to the inner part of the second threaded hole, and the second bolt passes through the dustproof net and is threadedly connected to the inner part of the third threaded hole, through the cooperation between the internally arranged gears and the transmission belt, pulling the pull ring can rotate the fan blades, thereby enabling the fan blades to rotate in all directions, so that the fan blades can be easily cleaned when cleaning, and the dustproof net can also be conveniently disassembled and installed.

[0004] Although the above technical solution can effectively prevent the intrusion of rainwater and the like through the external rainproof device, this structure weakens the flow of wind force through the louver air outlet. Utility Model Content

[0010] Furthermore, the included angle a formed by the lower plate of the bend and the blade body is 120 degrees to 160 degrees, preferably set to 135 degrees.

[0011] Furthermore, a waterproof coating is provided on the rainproof blades and the slope.

[0012] Furthermore, a sealing strip is provided at the junction of the end of the slope and the bottom of the outer frame.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present utility model.

[0027] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0028] like Figures 1 to 4 As shown, a wind and rainproof single-layer louver vent includes an outer frame 1, a plurality of groups of rainproof blades 3 arranged evenly spaced and in parallel within the frame of the outer frame 1, a rainproof baffle 2 arranged at the top of the outer frame 1 and extending toward the front end, and a rainproof sealing plate 4 arranged at the end of the outer frame 1. The rainproof blades 3 are connected to the frame body of the outer frame 1 through an adapter, so that the blades of the rainproof blades 3 can be rotated inward and outward, and the degree of closure of the blades can be flexibly adjusted.

[0029] The two sides of the rain shield 2 extend to the left and right sides of the outer frame 1. The rain shield 2 includes an upper convex arc plate 201 located in the middle, slanted eaves 202 located on both sides of the upper convex arc plate 201, and a plurality of horizontal drainage grooves 203 located on the upper surface of the upper convex arc plate 201; the upper convex arc plate 201 and the slanted eaves 202 are an integrated structure; the thickness of the upper convex arc plate 201 gradually decreases from the middle to the two sides, so that the upper surface of the upper convex arc plate 201 forms a curved surface structure, and the upper surface of the slanted eaves 202 is tilted outward and downward. The setting of the rain shield 2 can have a shielding effect on the one hand, and can guide rainwater to flow outward on the other hand, reducing the contact between rainwater and the fan blades inside the outer frame 1.

[0030] The rainproof blade 3 includes a blade body 302, a connecting shaft 301 located on both sides of the blade body 302, the connecting shaft 301 is used to connect with the inner wall of the outer frame 1, and a bend 303 is arranged at the upper end of the blade body 302, the bend 303 is a bending baffle with a ┓-shaped structure, and the angle a formed by the lower plate of the bend 303 and the blade body 302 is 120 degrees to 160 degrees, preferably set to 135 degrees. The bend 303 can effectively prevent rainwater from entering the louver vent under the action of wind. A waterproof coating is arranged on the rainproof blade 3, which can effectively prevent rainwater, dew, etc. from remaining on the blade.

[0031] The rainproof sealing plate 4 includes a plate body 401, the rear end of the plate body 401 is fixedly connected to the outer frame 1 and forms a closed structure at the end of the outer frame 1, the front end of the plate body 401 extends outward and downward so that the front wall of the plate body 401 is a slope 404, and a groove 402 is arranged at the top of the plate body 401, and a rainproof cloth roller 403 is built in the groove 402, and the rainproof cloth is rolled up on the rainproof cloth roller 403, and the starting end of the rainproof cloth is fixedly connected to the lowest rainproof blade 3 in the outer frame 1. The reason why rainwater is easily accumulated at the end of the outer frame 1 is that as the lowest blade is adjusted to the inclined shutter structure, it will inevitably form a thin gap under the outer frame 1, and the thin gap is very easy to cause rainwater to invade. For this reason, the utility model directly arranges the rainproof sealing plate 4 at the inner end of the outer frame 1, connects the end of the blade body 302 of the lowest rainproof blade 3 with the rolled rainproof cloth, and avoids the invasion of rainwater no matter how the blade is adjusted. In addition, the setting of the slope 404 prompts rainwater to flow out quickly.

[0032] A sealing strip 405 is provided at the junction of the end of the slope 404 and the bottom of the outer frame 1 to further prevent rainwater from entering. A waterproof coating is provided on the slope 404 to accelerate the outflow of rainwater from the slope 404.

[0033] The slope i of the slope 404 is set to 60 degrees to 80 degrees to ensure that rainwater is quickly discharged.

[0034] A cover plate 406 is disposed at the top of the groove 402 , and a wire groove is disposed on the cover plate 406 . The wire groove is used for a rainproof cloth to pass through, thereby further preventing rainwater from accumulating in the groove 402 .

[0035] The above only expresses the preferred implementation of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications, improvements and substitutions can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
