Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides an anti-condensation electrically heated glass door. Figure 1-Figure 4As shown, it includes a cabinet 1, a glass door body 2 is installed on the front of the cabinet 1, the glass door body 2 includes an aluminum alloy outer frame 21, a PVC frame 22 is installed on the inner side of the aluminum alloy outer frame 21, a glass plate is installed on the inner side of the PVC frame 22, a heating wire is installed on the outer wall of the PVC frame 22, an adhesive layer is arranged between the outer wall of the PVC frame 22 and the glass layer 23, the adhesive layer includes a first adhesive layer 27 and a second adhesive layer 28, and a heat insulating material 29 is arranged at the bottom of the second adhesive layer 28, a door seal 11 is arranged on the inner side of the cabinet opening of the cabinet 1, and a sealing strip 12 is arranged on the inner wall of the cabinet 1, and the cabinet 1 constitutes the main structure of the display cabinet for storing and displaying goods. The design of the cabinet 1 ensures sufficient strength and stability to support the glass door body 2 and the goods inside, and the aluminum alloy outer frame 21 provides solid support and protection for the glass door, and its excellent thermal conductivity also contributes to the uniform distribution of heat. The PVC frame 22 is installed on the inner side of the aluminum alloy outer frame 21. The PVC frame 22 not only provides good thermal insulation performance, but also effectively prevents the generation of condensation. The selection of PVC material also ensures that the door body is light and durable. The glass plate is installed on the inner side of the PVC frame 22. The glass plate provides a clear display field of view, allowing consumers to intuitively see the goods in the display cabinet. The design of the glass plate also fully considers the needs of thermal insulation and heat insulation. The heating wire is installed on the outer wall of the PVC frame 22 to prevent condensation on the surface of the glass door by uniform heating. The control of the heating wire can be intelligently adjusted according to the ambient temperature and humidity to achieve the best anti-condensation effect and reduce energy consumption. A glue layer is arranged between the outer wall of the PVC frame 22 and the glass layer 23, and the glue layer includes a first glue layer 27 and a second glue layer 28. These glue layers not only enhance the connection strength between the components of the glass door, but also provide good thermal insulation and sealing performance. A heat insulation material 29 is also arranged at the bottom of the second glue layer 28, which further improves the thermal insulation effect of the glass door. A door seal 11 is provided on the inner side of the cabinet opening of the cabinet body 1, and a sealing strip 12 is provided on the inner wall of the cabinet body 1. These sealing strips effectively prevent the intrusion of cold air and moisture, and ensure a constant environment inside the display cabinet.
[0024] In this embodiment, the glass plate includes a plurality of glass layers 23 , and an inert gas filling area 24 is provided between adjacent glass layers 23 to improve the heat insulation effect.
[0025] Specifically, the outer wall of the PVC frame 22 is provided with a heating wire installation groove 222, and the heating wire installation groove 222 is engaged with the heating wire to facilitate the installation and fixation of the heating wire.
[0026] Furthermore, the heating wire includes an auxiliary heating wire 25 and a main heating wire 26 for all-round heating.
[0027] Furthermore, a door seal slot 221 is provided on the top of the PVC frame 22 , and the door seal slot 221 is engaged with the door seal 11 to facilitate the installation and fixation of the door seal 11 .
[0028] Furthermore, an anti-theft windshield plate 223 is installed on the inner side of the PVC frame 22, and the sealing strip 12 is located between the anti-theft windshield plate 223 and the inner wall of the cabinet 1 to achieve an anti-theft windshield effect.
[0029] Furthermore, a clamping claw 211 is installed on the inner wall of the aluminum alloy outer frame 21 , and a fixing groove 224 is provided on the outer wall of the PVC frame 22 . The clamping claw 211 is engaged with the fixing groove 224 , so as to facilitate the clamping and fixing of the PVC frame 22 .
[0030] Further, the adhesive layer is made of silicone adhesive material, and the heat insulating material 29 is made of foam material. In the anti-condensation electric heating glass door of the present invention, the adhesive layer is a key part to ensure that the components are tightly combined, provide heat insulation and sealing effects. Specifically, the adhesive layer includes a first adhesive layer 27 and a second adhesive layer 28, both of which are made of silicone adhesive material. Silicone adhesive is a high-performance sealing material known for its excellent weather resistance, aging resistance and stability. It can maintain its elasticity and viscosity under a wide range of temperature and humidity conditions, thereby ensuring that the glass door always maintains excellent sealing performance during use. In addition, silicone adhesive also has excellent UV resistance, and will not crack or deform even if exposed to sunlight for a long time. In the present utility model, the adhesive layer made of silicone adhesive material not only tightly bonds the PVC frame 22 and the glass layer 23 together to form a solid and sealed overall structure, but also effectively blocks the transfer of heat between components through its good heat insulation performance, thereby enhancing the thermal insulation effect of the glass door. In order to further improve the heat insulation performance of the glass door, the utility model sets a heat insulation material 29 at the bottom of the second adhesive layer 28. The heat insulation material is made of foam material. Foam material is a lightweight, porous insulating material with excellent heat insulation and sound insulation performance. Its interior is composed of a large number of tiny bubbles, which can effectively block the heat transfer path in the material, thereby achieving a good heat insulation effect. At the same time, the foam material also has the advantages of being light, easy to process and low cost, making it an ideal choice of heat insulation material in the utility model. In the utility model, the heat insulation material 29 made of foam material is tightly filled between the second adhesive layer 28 and the PVC frame 22 or the glass layer 23 (the specific filling position depends on the actual situation), effectively blocking the direct transfer of heat between these components. This not only improves the overall heat insulation performance of the glass door, but also helps to reduce energy consumption and maintain a stable environment inside the display cabinet. At the same time, the softness of the foam material also ensures the buffering effect of the door body when closing, reducing the impact of noise and vibration on the display effect.
[0031] When the anti-condensation electric heating glass door of the utility model is in use, first, the glass door body 2 forms a solid and sealed door body through the composite structure of the aluminum alloy outer frame 21 and the PVC frame 22. The aluminum alloy outer frame 21 provides good support and protection, while the PVC frame 22 reduces heat transfer through its excellent heat insulation performance. Secondly, the heating wire installed on the outer wall of the PVC frame 22 is a key component to prevent condensation. When the ambient temperature and humidity are high, the heating wire will be powered on and heated, and the generated heat will be evenly transferred to the PVC frame 22 and the glass plate, thereby increasing the temperature of the door surface. This heating effect effectively prevents water vapor from condensing into water droplets on the surface of the door, that is, prevents the occurrence of condensation. In addition, the glue layer plays a bonding and sealing role in the glass door. The first glue layer 27 and the second glue layer 28 made of silicone glue material tightly bond the PVC frame 22 and the glass layer 23 together to form a seamless overall structure. This sealing structure effectively prevents the intrusion of moisture and cold air, thereby ensuring a dry and constant temperature environment inside the display cabinet. Finally, the addition of the heat insulating material 29 further enhances the heat insulating performance of the glass door. The heat insulating material 29 made of foam material is filled between the glue layer and the PVC frame 22 or the glass layer 23, effectively blocking the direct transfer of heat between these components. This heat insulating effect not only reduces energy consumption, but also improves the stability of the temperature inside the display cabinet.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
