Description

Technical Field

[0001] This utility model relates to a hollow glass door with a reduced conductivity coefficient. Background Technology

[0002] Refrigerator doors typically consist of multiple layers of glass fixed to a frame, with adjacent glass panes separated by edge spacers. This multi-layered glass structure reduces the door's conductivity, preventing cold air from easily transferring to the outside of the door. Figure 1 The diagram shows a typical door structure, consisting of a frame 1, an inner glass pane 2, an outer glass pane 3, and a spacer 4 between the inner and outer glass panes 2 and 3. The frame 1 has an integrally formed mounting platform 5 on the inner side of the inner glass pane 2, which protrudes to the right for positioning the inner glass pane 2. As can be seen from the diagram, the mounting platform 5 and the spacer 4 are on the same straight line in the longitudinal direction. This structure has the following defects: the cold air inside the door can easily be conducted to the outside of the door after passing through the mounting platform 5, the inner glass pane 2, the spacer 4, and the outer glass pane 3 in sequence, which will cause condensation around the outside of the door. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a hollow glass door with a reduced conductivity coefficient, effectively solving the issues mentioned in the background art.

[0004] The technical solution adopted in this utility model is:

[0005] A double-glazed door with reduced conductivity includes an L-shaped frame, an inner glass pane, an outer glass pane, and a spacer. The L-shaped frame protrudes to the right on the right side of its horizontal portion to form a mounting platform. The outer glass pane is fixed to the top of the vertical portion of the L-shaped frame. The inner glass pane is fixed to the outside of the mounting platform. The edge of the inner glass pane extends to the vertical portion of the L-shaped frame and abuts against the vertical portion of the L-shaped frame. The spacer is located directly above the horizontal portion of the L-shaped frame.

[0006] Preferably, the top of the mounting platform protrudes upward to form a boss above the horizontal portion of the L-shaped frame. The right side of the boss has multiple sealing ridges on the side that contacts the inner glass, and the outer ends of the sealing ridges are inclined toward the edge of the inner glass.

[0007] Preferably, the mounting platform has an inverted triangular structure.

[0008] Preferably, the mounting platform has an internal cavity.

[0009] Preferably, the cavity is divided into two chambers by a partition strip.

[0010] Preferably, the L-shaped frame, mounting platform, boss, sealing edge, and partition strip are integrally formed.

[0011] The innovative points of this utility model are as follows:

[0012] 1. Structural optimization design:

[0013] By designing the mounting platform as an inverted triangular structure and creating a cavity inside it, the path of cold air conduction is effectively reduced, thus lowering the heat conduction efficiency. The cavity is further divided into two chambers by a partition strip, enhancing the heat insulation effect. At the same time, this structure has better structural strength.

[0014] The top of the mounting platform protrudes upward to form a boss, and multiple inclined sealing ridges are set on the right side of the boss. These sealing ridges are in close contact with the inner glass, which significantly improves the sealing performance and prevents cold air leakage and condensation. Through the combination structure of the boss and sealing ridges, the mounting platform not only provides more stable support for the inner glass, but also ensures the sealing performance.

[0015] 2. Material and process improvements:

[0016] The L-shaped frame, mounting platform, boss, sealing edge, and partition strip are made with a one-piece molding process, which reduces seams and connection points, lowers the potential path of heat conduction, and improves the overall integrity and stability of the structure.

[0017] 3. Installation position adjustment:

[0018] The spacer is located directly above the horizontal part of the L-shaped frame, which changes the traditional layout where the mounting platform and the spacer are aligned vertically. This breaks the continuity of cold air conduction and further reduces the heat transfer coefficient.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. Significantly reduces the thermal conductivity and improves thermal insulation performance:

[0021] Structural optimization:

[0022] The mounting platform is designed with an inverted triangular structure. The interior is hollow and divided into two chambers by a partition strip, which effectively reduces the path of cold air conduction and reduces heat conduction efficiency. The hollow structure not only enhances the heat insulation effect, but also improves the overall structural strength.

[0023] The position of the spacer strip has been adjusted to be directly above the horizontal part of the L-shaped frame, breaking the traditional layout where the mounting platform and the spacer strip are aligned vertically, thus blocking the continuity of cold air conduction and further reducing the heat transfer coefficient.

[0024] Material improvements:

[0025] The one-piece molding process reduces seams and connection points, avoids potential heat conduction paths, and improves overall thermal insulation performance.

[0026] 2. Effectively reduces condensation:

[0027] Improved sealing structure:

[0028] The top of the mounting platform protrudes upward to form a boss, and multiple inclined sealing ridges are set on the right side of the boss. These sealing ridges are in close contact with the inner glass, which significantly improves the sealing performance and prevents cold air leakage.

[0029] The angled design of the sealing ridge enhances the fit with the inner glass, further preventing cold air leakage, thereby reducing condensation on the outside of the door and improving the aesthetics and user experience of the freezer.

[0030] 3. Enhance structural stability and durability:

[0031] One-piece molding process:

[0032] The L-shaped frame, mounting platform, boss, sealing edge, and partition strip are designed as a single piece, which reduces assembly seams and improves the overall structure and mechanical strength.

[0033] This process simplifies the production process, reduces the risk of potential failures due to seam issues, and extends the lifespan of the door.

[0034] 4. Energy-saving and environmentally friendly, reducing energy consumption:

[0035] High-efficiency heat insulation:

[0036] By blocking the cold air conduction path, the loss of cold air inside the freezer is reduced, thereby reducing the operating frequency and energy consumption of the compressor.

[0037] Environmental benefits:

[0038] The energy-saving design aligns with modern environmental protection concepts, helps reduce energy consumption and carbon emissions, and is suitable for commercial or household freezer scenarios with strict energy efficiency requirements.

[0039] 5. Combination of multifunctionality and practicality:

[0040] Installation stability:

[0041] The combination of the boss and the sealing ridge not only improves the sealing performance, but also enhances the support stability of the inner glass, preventing the glass from shifting due to vibration or temperature changes.

[0042] Wide adaptability:

[0043] This design can be widely used in various types of insulated glass doors, such as refrigerators and display cases, and has high market applicability.

[0044] This utility model achieves a comprehensive improvement in heat insulation performance, sealing performance, structural stability, and energy saving and environmental protection through innovative structural design, solving the problems of cold air conduction and condensation in traditional doors, while reducing production and maintenance costs.

[0054] like Figure 2 As shown, a double-glazed door with reduced conductivity includes an L-shaped frame 11, an inner glass pane 12, an outer glass pane 13, and a spacer 14. The L-shaped frame 11 protrudes to the right on the right side of its horizontal portion to form a mounting platform 15. The outer glass pane 13 is fixed to the top of the vertical portion of the L-shaped frame 11. The inner glass pane 12 is fixed to the outside of the mounting platform 15.

[0056] The mounting platform 15 has an inverted triangular structure.

[0058] The cavity 18 is divided into two cavities by a partition strip 19.

[0059] The L-shaped frame 11, mounting platform 15, boss 16, sealing ridge 17 and partition strip 19 are integrally formed.

[0060] The terms “left,” “right,” “up,” and “down” mentioned above are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

Therefore, they should not be construed as limitations on this utility model.

[0061] This invention significantly reduces the thermal conductivity coefficient and improves thermal insulation performance through structural optimization, material improvement, and installation position adjustment, while also reducing condensation. The detailed working principle is as follows:

[0062] 1. Structural optimization design:

[0063] Inverted triangular mounting platform and cavity structure:

[0064] The mounting platform is designed as an inverted triangle, with an internal cavity divided into two chambers by a partition strip. This structure reduces heat conduction in the following ways:

[0065] Blocking the path of cold air conduction: The inverted triangular sloping design increases the length of the cold air conduction path, while the cavity utilizes the low thermal conductivity of air (the thermal conductivity of air is much lower than that of solid materials) to reduce heat transfer;

[0066] The function of the partition strip is to divide the cavity into two independent chambers, further blocking heat convection and heat conduction, forming multiple heat insulation barriers;

[0067] Enhanced sealing between the boss and the sealing ridge:

[0068] The top of the mounting platform protrudes upwards to form a boss, and multiple inclined sealing ridges are provided on the right side of the boss. Its working principle is as follows:

[0069] Tight fit: The inclined design of the sealing ridge makes its outer end tilt towards the edge of the inner glass, and through elastic deformation, it makes tight contact with the glass, forming multiple sealing lines to prevent cold air leakage;

[0070] Reduce condensation: The sealing edge blocks the contact between cold air and outside humid air, preventing condensation from forming on the outside of the door due to temperature differences;

[0071] 2. Installation position adjustment:

[0072] Optimization of the position of the spacer strip:

[0073] The spacer strip is located directly above the horizontal portion of the L-shaped frame (instead of being aligned vertically with the mounting platform as in traditional designs), and its function is:

[0074] Breaking the continuity of heat conduction: In traditional designs, cold air can be conducted through a straight path from the mounting platform to the inner glass pane, then to the spacer, and finally to the outer glass pane; however, the new design, through staggered layout, forces the cold air to travel in a roundabout way, reducing heat conduction efficiency.

[0075] Reduce thermal bridging effect: The physical separation of the spacer from the mounting platform reduces thermal bridges caused by direct contact, further weakening heat transfer;

[0076] 3. Material and process improvements:

[0077] One-piece molding process:

[0078] The L-shaped frame, mounting platform, boss, sealing ridge, and partition strip are all integrally molded, which has the following advantages:

[0079] Reduce seams: Avoid heat leakage points at seams in traditional assembly and reduce potential heat conduction paths;

[0080] Structural stability: One-piece molding improves overall mechanical strength and reduces deformation or sealing failure caused by temperature changes or vibration;

[0081] 4. Overall effect:

[0082] Improved thermal insulation performance:

[0083] Through multiple designs such as cavities, partitions, and sealing ridges, the overall thermal conductivity (U-value) of the door is significantly reduced, thus reducing the loss of cold air inside the freezer.

[0084] Energy conservation and environmental protection:

[0085] With reduced cold air leakage, the compressor operates at a lower frequency, resulting in lower energy consumption and compliance with energy conservation and environmental protection requirements.

[0086] Anti-condensation and durability:

[0087] The optimized sealing structure effectively prevents condensation, and the one-piece molding process extends the service life of the door.

[0088] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
