Existing refrigerator doors are generally double-layered hollow glass doors, which have poor insulation. The door is often the main point of heat exchange between the refrigerator and the outside air, which reduces the refrigerator's refrigeration effect and increases its energy consumption. Another type is the door without a viewing window and insulation layer. This type of door has better insulation but cannot meet the requirements for observing the interior. There are also insulated doors with viewing windows. Generally, the inner and outer edges of the viewing window are wrapped with profiles, which has poor sealing and poor insulation. Therefore, this technical solution is proposed to improve the situation. Utility Model Content

[0016] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See Figures 1 to 4 This utility model discloses a novel heat-insulating door, mainly including a door body 1. A sealing edge is provided on the inner frame of the door body 1, so that when the door body 1 is closed, it can press the sealing edge against the door frame to form a seal and ensure the heat insulation effect. A hinge is provided on the side of the door body 1 to connect with the door frame, which facilitates the control of opening and closing of the door body 1. The door body 1 adopts a foam structure, and foam material is filled inside the door body 1 to improve the heat insulation effect of the door body 1.

[0018] A mounting frame 101 is installed on the upper part of the door body 1. The mounting frame 101 is glued to the door body 1 to ensure stability. The mounting frame 101 provides support for the transparent device installed inside. The mounting frame 101 is made of high-strength and corrosion-resistant materials, such as aluminum alloy, thermally broken aluminum, or PVC. PVC has a low thermal conductivity and good insulation to ensure long-term stability and safety. Inside the mounting frame 101, double-glazed windows 3 are installed as the transparent device. Nitrogen gas, an inert gas, is filled between the double-glazed windows 3. Nitrogen effectively reduces heat convection and enhances insulation. The design of double-glazed windows 3 not only improves insulation performance but also maintains good visibility, making it easy to observe the items inside the refrigerator.

[0019] To further enhance the insulation effect, a sealing strip 301 is installed at the connection between the transparent device and the mounting frame 101. The sealing strip 301 is made of highly elastic sponge strip, which can effectively prevent outside air from entering the refrigerator through gaps, thereby reducing heat exchange. To improve the strength and impact resistance of the window structure, an additional acrylic sheet 2 is installed on the outside of the door body 1 of the double-glazed glass 3. The acrylic sheet 2 is fixed to the mounting frame 101 by adhesive bonding. The acrylic sheet 2 abuts against the limiting plate on the mounting frame 101, ensuring the stability of the structure. This design facilitates the installation and positioning of the acrylic panel 2 and the double-glazed glass panel 3. During use, the sealing strip 301 is first fixed to the inside of the mounting frame 101. Then, the acrylic panel 2 is installed from the inside of the door body 1 into the mounting frame 101. Next, the double-glazed glass panel 3 is installed behind the acrylic panel 2. The edges of the acrylic panel 2 and the double-glazed glass panel 3 can directly abut against each other, or a sealing strip 301 can be left between the acrylic panel 2 and the double-glazed glass panel 3 to form a stable space, reducing heat entering the inside of the door body 1 and improving the insulation effect.

[0020] A snap-fit ​​groove is provided on the inner side of the mounting frame 101 to fix the pressure strip 302. The snap-fit ​​groove is set along the perimeter of the mounting frame 101 to ensure the uniform distribution and stable installation of the pressure strip 302. The pressure strip 302 is snapped into the snap-fit ​​groove by interference fit. Its inner side is provided with a pressing edge that tightly abuts against the edge of the double-glazed glass 3, further enhancing the sealing performance. The snap-fit ​​groove is located on the side of the mounting frame 101 near the inner side of the door body 1 and consists of two opposing snap-fit ​​pieces 102. The bottom of the snap-fit ​​piece 102 is provided with a snap-fit ​​rib for cooperating with the snap-fit ​​post 303 of the pressure strip 302 to achieve a stable snap-fit. The pressure strip 302 includes the snap-fit ​​rib that cooperates with the snap-fit ​​rib inside the snap-fit ​​groove. The snap-fit ​​post 303 has a protrusion on its top. When the pressure strip 302 is snapped into the snap-fit ​​groove, the protrusion engages with the snap-fit ​​edge, ensuring the stable installation of the pressure strip 302. The bottom of the snap-fit ​​post 303 is connected to the pressure edge, and the bottom of the pressure edge is provided with a triangular hook edge 304. The bottom of the snap-fit ​​post 303 has a certain thickness, which enhances the tightness of the fit between the pressure strip 302 and the side of the transparent device. The upper edge of the bottom of the pressure strip 302 seals the gap between the mounting frame 101 and the door body 1. The hook edge 304 stably seals the gap between the double-glazed glass 3 and the mounting frame 101, preventing heat flow in the gap, improving the sealing effect and enhancing the heat insulation.

[0021] The acrylic panel 2 and double-glazed glass 3 not only maintain good transparency, meeting the needs of observing internal items, but also significantly improve the heat preservation effect and reduce the energy consumption of the refrigerator through the comprehensive application of double-glazed glass 3, sealing strip 301, snap-fit ​​groove and pressure strip 302. At the same time, the interference fit between pressure strip 302 and snap-fit ​​groove and the triangular hook edge 304 design of the pressure edge ensure the stability and sealing of the window structure, extending the service life of the refrigerator. It not only meets the observation needs, but also achieves a significant improvement in heat preservation performance, providing a strong guarantee for the long-term preservation of biological products.
