Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-fog and breathable structures for aluminum alloy doors and windows, and in particular to an anti-fog and breathable structure for aluminum alloy doors and windows. Background Technology
[0002] Aluminum alloy doors and windows are door and window products made primarily of aluminum alloy. They combine the strength of metal with the aesthetics of modern craftsmanship and are widely used in the construction industry. With their advantages of high strength, customizability, and energy efficiency, aluminum alloy doors and windows have become the mainstream choice for modern buildings, and are especially recommended for mid-to-high-end residences that prioritize sound and heat insulation.
[0003] Existing aluminum alloy doors and windows consist of two main parts: the frame and the glass. However, in actual use, fogging and condensation easily occur on the glass of aluminum alloy doors and windows. Since aluminum alloy doors and windows do not have anti-fogging and anti-condensation components, fogging and condensation on the glass will affect the indoor light transmission effect, and this problem cannot be easily solved. Therefore, existing aluminum alloy doors and windows without anti-fogging and anti-condensation functions are inconvenient to use. To address this, we provide an anti-fogging and breathable structure for aluminum alloy doors and windows. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing aluminum alloy doors and windows in terms of their lack of anti-fog and anti-condensation functions, and to provide an anti-fog and breathable structure for aluminum alloy doors and windows.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum alloy door and window anti-fog and ventilation structure, comprising: a heating mechanism, the heating mechanism including a frame, the inner side of the frame being provided with glass, the number of glass being two, each of the two glass having a heating film on one side, the heating film being fixedly connected to the glass, both sides of the frame being provided with a blower mechanism, the blower mechanism including a connecting frame, the connecting frame having an air outlet hole, an air pump being sleeved inside the connecting frame, a heating coil being provided inside the connecting frame, the heating coil being fixedly connected to the connecting frame, one end of the air pump having an air supply pipe, and one end of the air supply pipe having an air distribution pipe.
[0006] In a preferred embodiment, the air pump is fixedly connected to the connecting frame, and the air supply pipe is fixedly connected to the air pump.
[0007] In a preferred embodiment, the gas distribution pipe is fixedly connected to the gas transmission pipe, and fixing blocks are provided on both sides of the connecting frame.
[0008] In a preferred embodiment, the fixing block is fixedly connected to the connecting frame, and bolts are fitted inside both the fixing block and the frame.
[0009] In a preferred embodiment, the bolt is slidably connected to the fixing block, and the bolt is threadedly connected to the frame.
[0010] In a preferred embodiment, a fixing adhesive layer is provided on one side of the glass, and the fixing adhesive layer is fixedly connected to both the glass and the frame.
[0011] In a preferred embodiment, mounting grooves are provided on both outer surfaces of the frame.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] This invention, by incorporating a heating mechanism, allows both panes of glass in aluminum alloy doors and windows to be heated, preventing water vapor condensation due to low temperatures. This eliminates fogging and condensation on the glass, maintaining its light transmittance even in ventilated conditions. Simultaneously, a blower mechanism generates hot air to dry residual moisture on the glass's outer surface and also blocks water vapor from adhering to the glass's perimeter, preventing excessive external water vapor from adhering to the glass's surface. The blower mechanism works in conjunction with the heating mechanism, and an air pump ensures rapid airflow within the connecting frame, dissipating heat from the frame to the outside and thus defogging and protecting the glass's outer surface.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: As Figures 1-7 As shown, this utility model provides a technical solution: an aluminum alloy door and window anti-fog and ventilation structure, including: a heating mechanism 1, the heating mechanism 1 includes a frame 11, and two pieces of glass 12 are provided on the inner side of the frame 11. Each of the two pieces of glass 12 is provided with a heating film 13 on one side, and the heating film 13 is fixedly connected to the glass 12. Both sides of the frame 11 are provided with a blower mechanism 2, the blower mechanism 2 includes a connecting frame 21, an air outlet 22 is provided on the connecting frame 21, an air pump 23 is sleeved inside the connecting frame 21, a heating coil 24 is provided inside the connecting frame 21, the heating coil 24 is fixedly connected to the connecting frame 21, one end of the air pump 23 is provided with an air supply pipe 25, one end of the air supply pipe 25 is provided with a distribution pipe 26, the air pump 23 is fixedly connected to the connecting frame 21, the air supply pipe 25 is fixedly connected to the air pump 23, and the distribution pipe 26 is fixedly connected to the air supply pipe 25.
[0025] In this embodiment, by setting two glass panes 12 with a certain distance between them, the two glass panes 12 can form a space, allowing the heat generated by the two heating films 13 to dissipate to both sides. As a result, the temperature of the outer surface of the glass panes 12 can be increased, and the water vapor in the outside will not fog or condense due to the low temperature of the glass panes 12. The air vents 22 are opened on the connecting frame 21 and are evenly distributed, so the hot air inside the connecting frame 21 can be blown to the outer surface of the glass panes 12 more evenly, so that the outer surface of the glass panes 12 will not be covered with water vapor, thus enabling it to be used in conjunction with the heating mechanism 1. The heating coil 24 is set and can generate heat to heat the air inside the connecting frame 21. In addition, the air distribution pipe 26 is set and can split the air delivered by the air supply pipe 25 to both sides, thus ensuring that the air outlet of the connecting frame 21 is more even.
[0026] Example 2: As Figures 1-7 As shown, fixing blocks 27 are provided on both sides of the connecting frame 21. The fixing blocks 27 are fixedly connected to the connecting frame 21. Bolts 28 are sleeved inside the fixing blocks 27 and the frame 11. The bolts 28 are slidably connected to the fixing blocks 27 and threadedly connected to the frame 11. A fixing adhesive layer 14 is provided on one side of the glass 12. The fixing adhesive layer 14 is fixedly connected to both the glass 12 and the frame 11.
[0027] In this embodiment, by setting a fixing adhesive layer 14, which can simultaneously fix and connect to the frame 11 and the glass 12, the fixing adhesive layer 14 can stably fix the glass 12. Furthermore, the fixing adhesive layer 14 has waterproof properties, so external water vapor will not enter the interior of the two glass 12, thus ensuring that the light transmittance of the glass 12 is not affected.
[0028] Working principle:
[0029] like Figures 1-7As shown, in use, the blower mechanism 2 can be installed on both sides of the heating mechanism 1. Then, the connecting frame 21 drives the fixing block 27 into the mounting groove 15 on the frame 11, and the bolt 28 passes through the fixing block 27 and is threaded to the frame 11, ensuring the blower mechanism 2 is securely installed on both sides of the frame 11. If ventilation is required, fog and condensation will appear on the glass 12. At this time, the heating film 13 is energized and heated, causing the temperature of the glass 12 to rise, thus eliminating the fog and condensation on the outer surface of the glass 12. Then, the heating coil 24 is... When energized, the heating coil 24 heats the air inside the connecting frame 21. Then, the air pump 23 is activated to draw in outside air and deliver it into the connecting frame 21. The drawn air is transported through the air supply pipe 25 and the air distribution pipe 26 inside the connecting frame 21 and heated. The hot air inside the connecting frame 21 is then exhausted and blown onto the outer surface of the glass 12 through the air outlet 22. As a result, the fog and condensation on the outer surface of the glass 12 can be removed more quickly, and the outer surface of the glass 12 can be kept dry, thus preventing fog and condensation from occurring.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
