[0002] In traditional French-style refrigerators, the upper section typically consists of two independent refrigerator doors, sealed together by a hinged flap. While this flap ensures a good seal by flipping the door open and closed, it also presents some challenges. First, space must be reserved inside the refrigerator door to accommodate the flap, sacrificing some door volume and reducing storage space. Second, the flap generates noise during operation, impacting the user experience when opening and closing the door and detracting from the overall premium feel of the refrigerator. Summary of the Invention

[0017] A third aspect of the present invention provides a refrigeration device, including the door seal assembly as described above; or, This includes doors as described above.
[0018] According to the door sealing assembly provided in the first aspect of the present invention, through the rigid support of the main door seal and the connecting plate, the main door seal can automatically deform and fit tightly against the other door when the door is closed, achieving reliable sealing between the two doors and between the door and the cabinet without the need for a traditional flip beam. Eliminating the flip beam eliminates the need for pre-reserved installation space inside the door, significantly increasing the door volume. Shelves can be removed horizontally, drawers and shelves can be further deepened, and bottle frames can be widened to the edges, greatly improving the volumetric efficiency of the refrigeration equipment and meeting more storage needs of users. The multiple independent closed chambers formed after the main door seal deforms effectively block air convection, reduce the convective heat transfer coefficient, form a thermal barrier, improve sealing and insulation effects, reduce heat exchange inside and outside the refrigeration equipment, reduce energy consumption, and maintain stable temperature inside the cabinet. Eliminating the flip beam also eliminates the operating noise generated by the flip beam, making door opening and closing quieter and improving the user experience of the refrigeration equipment. Meanwhile, this door seal assembly can be directly applied to existing refrigeration equipment platforms with ordinary single or double axis hinges without modifying the cabinet structure or replacing the hinges, significantly reducing product modification costs.

No space is needed inside the door body for the flip beam installation, the shelves and drawers are deeper, and the bottle frames are widened to the edges, significantly increasing the door's volume ratio and allowing it to hold more items, meeting diverse storage needs and solving the problem of volume sacrifice caused by traditional flip beams. The flip beam-free design completely eliminates the noise of the flip beam during operation, making door opening and closing quieter. The elastic material and thin-walled corner design of the main door seal reduce deformation resistance, and combined with ordinary single and double-axis hinges, the door closes smoothly automatically without additional force, providing a smoother opening and closing experience. The multiple independent closed chambers formed after the main door seal deforms, combined with the double sealing of the flexible seals at both ends and the auxiliary door seal, effectively block heat exchange between the inside and outside of the cabinet, reduce convective heat transfer, and lower the energy consumption of the refrigeration equipment. The heating element of the auxiliary door seal prevents condensation, avoiding condensation affecting sealing performance and further ensuring stable insulation.
[0020] According to the third aspect of the refrigeration equipment provided by the present invention, the refrigeration equipment achieves a beam-free seal through a door seal assembly, freeing up storage space in both the door and the cabinet. The door shelves and drawers are deeper, the bottle frames are wider, the cabinet cavity layout is more regular, and the overall volume ratio is significantly improved, meeting more storage needs of users and solving the problem of traditional French refrigerators sacrificing storage space due to the flip beam. The dual-sealing design of multiple independent closed chambers in the main door seal and the auxiliary door seal effectively blocks the convection of hot and cold air, reduces cold loss, and lowers the operating load of the refrigeration system. Intelligent control of the heating element prevents condensation from affecting the seal, further ensuring heat insulation and significantly reducing the energy consumption of the refrigeration equipment. The beam-free design completely eliminates the operating noise of the flip beam, making door opening and closing quieter. The elastic material and thin-walled corner design of the main door seal, combined with ordinary single and double-axis hinges, ensures smooth automatic door closing without additional force, improving the user's door opening and closing experience.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0029] like Figures 1 to 5 As shown, a first aspect of the present invention provides a door sealing assembly, comprising: The main door seal 100 is located on the side of the door 120 facing the box. A stop block 102 is provided inside the main door seal 100. The main door seal 100 is adapted to switch between an initial state and a deformed state. In the deformed state, the stop block 102 is adapted to divide the interior of the main door seal 100 into multiple independent closed chambers 104. Connecting plate 106 is fixed to the side of the main door seal 100 facing the box.
[0030] According to the door sealing assembly provided in the first aspect of the present invention, the main door seal 100, with the rigid support of the connecting plate 106, allows the main door seal 100 to automatically deform and fit tightly against the other door 120 when the door 120 is closed. This achieves reliable sealing between the two doors 120 and between the door 120 and the cabinet without the need for a traditional flip beam. Eliminating the flip beam eliminates the need for pre-reserved installation space within the door 120, significantly increasing its volume. Shelves can be removed horizontally, drawers and shelves can be further deepened, and bottle frames can be widened to the edges, greatly improving the volumetric efficiency of the refrigeration equipment and meeting more storage needs of users. The multiple independent closed chambers 104 formed after the main door seal 100 deforms effectively block air convection, reduce the convective heat transfer coefficient, form a thermal barrier, improve sealing and insulation effects, reduce heat exchange between the inside and outside of the refrigeration equipment, lower energy consumption, and maintain stable temperature inside the cabinet. Eliminating the flip beam also eliminates the operating noise generated by the flip beam, making the door 120 quieter and improving the user experience of the refrigeration equipment. Meanwhile, this door seal assembly can be directly applied to existing refrigeration equipment platforms with ordinary single or double axis hinges without modifying the cabinet structure or replacing the hinges, significantly reducing product modification costs.
[0031] Please continue reading Figures 1 to 5 The door seal assembly provided in the first aspect of the present invention achieves a non-flip beam seal through the setting of a main door seal 100 deformation seal, a connecting plate 106 support, and an internal baffle 102 separating the chambers.
[0032] The main door seal 100 is made of elastic material and is elongated in shape. It is located on the side of the door 120 facing the enclosure, and its length is adapted to the width of the door 120. Multiple baffles 102 are evenly arranged along the length of the main door seal 100. The baffles 102 are integrally formed with the main door seal 100 and are made of the same elastic material. The main door seal 100 has two working states: an initial state and a deformed state. In the initial state, the main door seal 100 is not compressed, and there are gaps between the internal baffles 102, with the chambers interconnected. When the door 120 is closed, the main door seal 100 is compressed by the enclosure and the connecting plate 106, entering a deformed state. At this time, the multiple baffles 102 abut against each other, or the baffles 102 abut against the inner wall of the main door seal 100, dividing the interior of the main door seal 100 into multiple independent closed chambers 104, forming multiple heat insulation barriers.
[0033] Along a cross-section perpendicular to the length of the main door seal 100, the main door seal 100 is polygonal, with multiple corners 108. The wall thickness at at least some of the corners 108 is less than the wall thickness of other parts of the main door seal 100. This thin-walled corner design reduces the resistance when the main door seal 100 deforms, ensuring that the main door seal 100 can deform smoothly when the door 120 is closed, without affecting the automatic closing effect of the door 120.
[0034] The connecting plate 106 is a rigid flat plate, fixed to the side of the main door seal 100 facing the enclosure. It is tightly fitted to the main door seal 100 by adhesive or bolt connection, with no gaps at the connection surface. Along the length of the main door seal 100, the length of the connecting plate 106 is greater than or equal to the length of the main door seal 100, ensuring that the main door seal 100 can be evenly stressed along its length. The side of the connecting plate 106 away from the main door seal 100 is a flat surface. When the door 120 is closed, this flat surface contacts the corresponding surface of the enclosure or another door 120, forming a rigid support. This ensures that the main door seal 100 deforms evenly under compression, avoiding sealing gaps caused by uneven local stress.
[0035] According to one embodiment of the present invention, the cross-section of the main door seal 100 is at least polygonal along the length direction perpendicular to the main door seal 100.
[0036] In one embodiment of the present invention, the main door seal 100 is polygonal, preferably octagonal, along a cross-section perpendicular to its length. The lengths of the sides of the cross-section are adapted to the fitting gap between the door body 120 and the housing. The polygonal cross-section is composed of multiple straight sides and corners 108 connected sequentially, with smooth transitions between the sides and corners 108, ensuring sufficient structural stability of the main door seal 100 while reserving reasonable space for deformation.
[0037] The main door seal 100 is fixed to the side of the door 120 facing the enclosure. One side of its polygonal cross-section is tightly fitted with the connecting plate 106, while the other side faces the enclosure. The contour of the polygonal cross-section is optimized so that when the door 120 is closed, the polygonal side of the main door seal 100 can form surface contact with the surface of the enclosure and the main door seal 100 of the other door 120, avoiding sealing gaps caused by point contact or line contact and ensuring a sealing effect.
[0038] The polygonal cross-section design allows the main door seal 100 to undergo directional deformation at the corner 108 when compressed by the housing and connecting plate 106, rather than random twisting. During the deformation process, all sides of the polygon are subjected to force simultaneously, ensuring that the main door seal 100 deforms uniformly as a whole. No additional force is required when closing the door 120, and the automatic closing effect of the door 120 is not affected.
[0039] The polygonal cross-section main door seal 100 can achieve sealing between the two doors 120 and between the door 120 and the box through its own deformation, without the need for traditional flip beams. This completely eliminates the flip beam structure, avoids the flip beam occupying the volume of the door 120, simplifies the internal design of the door 120, and reduces the manufacturing complexity of the door 120.
[0040] The polygonal cross-section allows the main door seal 100 to fit together with the cabinet and the other door 120 on multiple sides, resulting in a larger contact area and a tighter seal. This effectively blocks the exchange of hot and cold air between the inside and outside of the cabinet, reduces the energy consumption of the refrigeration equipment, and prevents condensation caused by external moisture entering the cabinet.
[0041] According to one embodiment of the present invention, along the length direction perpendicular to the main door seal 100, the cross section of the main door seal 100 has a plurality of corners 108, and the wall thickness at at least some of the corners 108 is less than the wall thickness of other parts of the main door seal 100.
[0042] In one embodiment of the present invention, along a cross-section perpendicular to the length of the main door seal 100, the wall thickness at multiple corners 108 of the main door seal 100 is less than the wall thickness of other parts. The corners 108 adopt a thin-wall design, while the other straight side parts adopt a relatively thick wall thickness, forming a structure with thick edges and thin corners, which not only ensures the overall structural strength of the main door seal 100, but also reduces the deformation resistance at the corners 108.
[0043] The thin-walled area at corner 108 transitions smoothly with the thick-walled area on the straight side, without obvious steps or abrupt changes, thus avoiding stress concentration. The material of the thin-walled area is the same as that of the other parts of the main door seal 100, ensuring flexibility during deformation. At the same time, the length of the thin-walled area is adapted to the angle of the polygonal cross-section corner 108, allowing deformation to proceed in a preset direction.
[0044] When the door 120 is closed, the housing and connecting plate 106 apply a compressive force to the main door seal 100. The thin-walled corner 108 deforms first, causing the polygonal cross-section of the entire main door seal 100 to adjust its shape, so that the main door seal 100 is in close contact with the mating surface. When the door 120 is opened, the elastic restoring force of the thin-walled corner 108 can cause the main door seal 100 to quickly return to its initial state, without affecting the smoothness of opening the door 120.
[0045] The thin-walled design at corner 108 reduces the resistance when the main door seal 100 deforms. When the door 120 is closed, the main door seal 100 can be pushed to complete the sealing deformation without additional force, avoiding the door 120 from failing to close automatically due to excessive deformation resistance, thus ensuring the ease of use of the refrigeration equipment.
[0046] The thin-walled corner 108 distributes deformation stress more evenly across the entire cross section, avoiding cracking, aging, or elastic failure caused by stress concentration at the thick-walled corner 108, extending the service life of the main door seal 100, and reducing the maintenance cost of the refrigeration equipment.
[0047] According to one embodiment of the present invention, there are multiple baffles 102, and in the deformed state, the multiple baffles 102 abut against each other to form a closed cavity 104; And / or, In the deformed state, multiple blocks 102 abut against the inner wall of the main door seal 100 to form a closed chamber 104.
[0048] In one embodiment of the present invention, a plurality of blocks 102 are provided inside the main door seal 100. The blocks 102 are elastic protrusions integrally formed with the main door seal 100 and are made of the same material as the main door seal 100. The plurality of blocks 102 are evenly distributed along the cross-sectional direction of the main door seal 100. Some blocks 102 extend toward the inner wall of the main door seal 100, and some blocks 102 are arranged correspondingly to each other to form an alternating layout.
[0049] When the main door seal 100 is in its initial state, there are gaps between the multiple blocks 102, and the interior is a connected cavity. When the door 120 is closed and the main door seal 100 is compressed into a deformed state, the multiple blocks 102 abut against each other, or the blocks 102 abut against the inner wall of the main door seal 100, dividing the interior of the main door seal 100 into multiple independent closed chambers 104. The number of closed chambers 104 is adapted to the layout of the blocks 102, forming a multi-layered isolation structure.
[0050] The enclosed chamber 104 is a sealed space with no air circulation, effectively blocking heat transfer through air convection. The baffle 102 fits tightly against the inner wall of the main door seal 100 without any air leakage gaps, ensuring the airtightness of each enclosed chamber 104 and forming multiple heat insulation barriers.
[0051] Multiple independent enclosed chambers 104 block air convection inside the main door seal 100, significantly reducing the convective heat transfer coefficient. Compared with traditional hollow door seals, the insulation effect is more significant, which can reduce the energy consumption of refrigeration equipment and maintain stable temperature inside the cabinet.
[0052] The combination of the stop block 102 and the closed chamber 104 makes the structure of the main door seal 100 more stable, and it will not collapse or twist excessively when deformed. It can always maintain effective contact with the mating surface, ensuring that the sealing effect does not decrease, while avoiding elastic fatigue of the main door seal 100 due to long-term deformation.
[0053] According to one embodiment of the present invention, the main door seal 100 is made of an elastic material.
[0054] In one embodiment of the present invention, the main door seal 100 is made of an elastic material, preferably flexible rubber or elastic plastic, which has good flexibility, elastic recovery force and low temperature resistance, can adapt to the low temperature environment inside the refrigeration equipment, and is not easy to age or crack during long-term deformation and recovery.
[0055] The hardness of the elastic material has been optimized to ensure that the main door seal 100 can generate sufficient deformation to achieve a seal when compressed, while also possessing sufficient structural strength to prevent the door 120 from failing to return to its initial state due to insufficient elasticity when opened. The polygonal cross-section, thin-walled corner 108, and internal stop 102 of the main door seal 100 are all designed based on the characteristics of the elastic material to ensure the matching of structural and material properties.
[0056] The main door seal 100 is manufactured by a molding process. The elastic material forms a pre-designed polygonal cross section, thin-walled corner 108 and internal stop block 102 structure in the mold. No additional processing is required after molding, ensuring the integrity and precision of the structure. At the same time, the molding process can ensure that the material of each part of the main door seal 100 is uniform, avoiding sealing defects caused by splicing.
[0057] The flexibility of the elastic material allows the main door seal 100 to easily adapt to compression deformation and fit tightly against the sealing surface; when the door 120 is opened, the elastic restoring force can drive the main door seal 100 to quickly return to its original shape, without affecting the smooth opening and closing of the door 120, and at the same time avoiding sealing gaps caused by material rigidity.
[0058] The elastic material has a certain elastic deformation capability, which can adapt to the tiny bumps and depressions on the surface of the cabinet and the other door 120, fill the tiny gaps in the mating surface, make the seal tighter, further reduce heat exchange and moisture intrusion, and improve the performance of the refrigeration equipment.
[0059] According to one embodiment of the present invention, a flexible seal is also included, which is disposed at both ends of the main door seal 100 along the length direction of the main door seal 100.
[0060] In one embodiment of the present invention, the flexible seal is a closed-cell sponge or a flexible rubber strip, which has good elasticity and sealing performance, and is soft and non-absorbent. The flexible seal is disposed at both ends of the main door seal 100 along the length direction of the main door seal 100, and is tightly fitted to the end face of the main door seal 100, covering the entire cross-sectional area of the end face of the main door seal 100.
[0061] The flexible seal is connected to the main door seal 100 by adhesive bonding or embedded fixing, ensuring a firm connection that is not easily detached. After installation, the outer side of the flexible seal fits against the mounting surface of the door body 120, while the inner side seals against the internal cavity of the main door seal 100, forming an end-closed structure.
[0062] When the main door seal 100 is in a deformed state, the flexible seals at both ends can be compressed or extended synchronously with the deformation of the main door seal 100 to fill the gap between the end of the main door seal 100 and the door body 120 and the box body; at the same time, the flexible seals can prevent air from entering the internal cavity from the end of the main door seal 100, ensuring the sealing of multiple closed chambers 104 and avoiding end leakage from affecting the heat insulation effect.
[0063] The flexible seal fills the gaps between the two ends of the main door seal 100 and the door body 120 and the cabinet, preventing air from flowing from the inside and outside of the cabinet through the ends. This solves the problem of easy air leakage at the ends of traditional door seals, and makes the seal of the main door seal 100 form a closed loop along the entire length, further improving the heat insulation and moisture-proof performance of the refrigeration equipment.
[0064] The flexible seal has a certain buffering effect. When the door 120 is opened and closed, it can absorb the collision force between the end of the main door seal 100 and the door 120 and the cabinet, reducing vibration and noise. Combined with the design without a flip beam, it completely eliminates the noise of the flip beam operation and improves the high-end user experience of the refrigeration equipment.
[0065] In addition, the flexible seal has a certain buffering effect. When the door 120 is opened and closed, it can absorb the collision force between the end of the main door seal 100 and the door 120 and the cabinet, reducing vibration and noise. Combined with the design without a flip beam, it completely eliminates the noise of the flip beam operation and improves the high-end user experience of the refrigeration equipment.
[0066] According to one embodiment of the present invention, along the length direction of the main door seal 100, the length of the connecting plate 106 is greater than or equal to the length of the main door seal 100, and the length of the connecting plate 106 is less than or equal to the height of the door body 120.
[0067] In one embodiment of the present invention, along the length of the main door seal 100, the length of the connecting plate 106 is greater than or equal to the length of the main door seal 100, while the length of the connecting plate 106 is less than or equal to the height of the door body 120. The connecting plate 106 is a rigid flat plate, fixedly installed on the side of the main door seal 100 facing the box body, and its length covers the entire length range of the main door seal 100, or extends beyond both ends of the main door seal 100 by a certain distance, ensuring that every part of the main door seal 100 can be supported and compressed by the connecting plate 106.
[0068] The connecting plate 106 is tightly connected to the main door seal 100 by adhesive or bolts, with no gaps at the connection surface, ensuring that the compressive force can be evenly transmitted to the main door seal 100. The side of the connecting plate 106 away from the main door seal 100 is a flat surface. When the door 120 is closed, this flat surface contacts the corresponding surface of the box or another door 120, forming a rigid support, so that the main door seal 100 is subjected to uniform stress deformation.
[0069] When the door 120 is closed, the full-length support of the connecting plate 106 ensures that the deformation of the main door seal 100 along its length is uniform and consistent, preventing any sealing gaps caused by excessive or insufficient local stress. The portion of the connecting plate 106 that extends beyond the main door seal 100 can cooperate with the installation structure of the door 120 to further fix the position of the main door seal 100, preventing the main door seal 100 from shifting or deforming during long-term use.
[0070] The connecting plate 106 covers the main door seal 100 along its entire length, so that the compressive force is evenly distributed along the length of the main door seal 100, and the deformation of each part of the main door seal 100 is consistent. This avoids poor sealing caused by insufficient local deformation or elastic fatigue caused by excessive local deformation, and ensures a uniform and reliable sealing effect along the entire length.
[0071] The rigid connecting plate 106 is fixed along its entire length, which can limit the lateral displacement of the main door seal 100. During the opening and closing of the door 120, the main door seal 100 always remains in the preset installation position and will not be displaced due to vibration or deformation, thus ensuring the accuracy of the sealing position and extending the service life of the main door seal 100.
[0072] The rigid support of the connecting plate 106 enables the extrusion pressure to be transmitted to the main door seal 100 more efficiently, avoiding insufficient deformation caused by force dispersion. The main door seal 100 can achieve a tight seal with a small extrusion stroke, reducing the impact force when the door 120 is closed, and improving the reliability of the seal.
[0073] According to one embodiment of the present invention, an auxiliary door seal 110 is also included, which is disposed on at least one side of a pair of door bodies 120 opposite to each other, and a heating element 112 is disposed inside the auxiliary door seal 110.
[0074] In one embodiment of the present invention, an auxiliary door seal 110 is disposed on at least one side of a pair of door bodies 120 opposite to each other, and cooperates with the main door seal 100 to form a double seal. The auxiliary door seal 110 is made of an elastic material, and its shape is adapted to the mating gap of the two door bodies 120. One side of it is fixed to the door body 120, and the other side faces the other door body 120, and fits against the auxiliary door seal 110 or the main door seal 100 of the other door body 120.
[0075] A heating element 112 is installed inside the auxiliary door seal 110. The heating element 112 is a flexible heating wire or heating film, which is evenly distributed along the length of the auxiliary door seal 110. The heating element 112 is electrically connected to the control system of the refrigeration equipment and can automatically start or stop according to the ambient temperature. It generates heat to raise the temperature of the auxiliary door seal 110 and the surrounding area, preventing moisture in the air from condensing on the surface of the door seal.
[0076] The auxiliary door seal 110 and the main door seal 100 form an overlapping sealing area at the joint of the two door bodies 120. The main door seal 100 is responsible for the main heat insulation sealing, while the auxiliary door seal 110 is responsible for auxiliary sealing and anti-condensation. The two work together to ensure the sealing effect and solve the condensation problem.
[0077] The heating element 112 can effectively increase the temperature of the door seal area, prevent moisture condensation caused by the temperature difference between the inside and outside of the cabinet, prevent water droplets from appearing on the door seal surface, avoid water droplets dripping and causing dampness around the cabinet, and prevent condensation from affecting the sealing performance of the door seal, thus improving the user experience of the refrigeration equipment.
[0078] The auxiliary door seal 110 and the main door seal 100 form a double seal, further blocking the exchange of heat and cold between the inside and outside of the cabinet and reducing energy consumption. At the same time, the auxiliary door seal 110 can fill any small sealing gaps that may exist in the main door seal 100, improve the overall sealing reliability, and ensure stable temperature inside the cabinet.
[0079] The anti-condensation function of the heating element 112 enables the refrigeration equipment to adapt to high temperature and high humidity environments such as humid areas in the south, and avoids door seal failure caused by excessive humidity.
[0080] According to one embodiment of the present invention, the auxiliary door seal 110 is integrally formed with the main door seal 100.
[0081] In one embodiment of the present invention, the auxiliary door seal 110 and the main door seal 100 are made of the same elastic material and manufactured by a molding process, with no splicing gaps between them, forming a complete door seal as a whole. The auxiliary door seal 110 is located on one side of the main door seal 100 and smoothly transitions with the polygonal cross-section of the main door seal 100, together forming an integral structure adapted for the installation of the door body 120.
[0082] The integrated main door seal 100 and auxiliary door seal 110 are fixed to the door body 120 via a connecting plate 106, eliminating the need for separate positioning and fixing during installation and simplifying the assembly process. The auxiliary door seal 110 has the same length as the main door seal 100, extending along the length of the door body 120, and precisely fits with the auxiliary door seal 110 of another door body 120 or the main door seal 100, forming a dual-seal and anti-condensation integrated structure.
[0083] The integrally molded door seal has uniform material and consistent elasticity. The deformation of the auxiliary door seal 110 and the main door seal 100 is coordinated and synchronized. When the door 120 is closed, both can adapt to the shape of the mating surface at the same time to achieve a tight seal. The heating element 112 is embedded in the preset cavity of the auxiliary door seal 110 and is compatible with the integrally molded door seal structure without affecting the overall elasticity and sealing performance of the door seal.
[0084] The auxiliary door seal 110 and the main door seal 100 are integrally molded, which reduces the number of parts, eliminates the need for additional connection structures or assembly steps, simplifies the production and assembly process, reduces manufacturing costs and assembly errors, and improves production efficiency.
[0085] The one-piece molding structure makes the deformation of the auxiliary door seal 110 and the main door seal 100 coordinated and consistent, resulting in a smaller sealing gap. At the same time, the heat generated by the heating element 112 can be partially transferred to the main door seal 100, which helps to increase the temperature of the main door seal 100 area, further reducing the risk of condensation and achieving synergistic optimization of sealing and anti-condensation.
[0086] The one-piece molding without splicing gaps avoids the problem of loosening and falling off of the connection caused by long-term deformation or vibration of the split structure. The overall structural strength of the door seal is higher and the service life is longer. At the same time, it avoids the decline in sealing and heat insulation performance caused by air leakage at the splice.
[0087] According to one embodiment of the present invention, an isolation member 114 is provided inside the auxiliary door seal 110. The isolation member 114 is adapted to divide the auxiliary door seal 110 into a heating chamber 116 and an isolation chamber 118. The isolation chamber 118 is disposed near the door body 120, and the heating member 112 is disposed in the heating chamber 116.
[0088] In one embodiment of the present invention, an insulating member 114 is provided inside the auxiliary door seal 110. The insulating member 114 is made of heat-insulating cotton or a flexible heat-insulating film, which is lightweight and has excellent heat insulation performance. The insulating member 114 extends along the length direction of the auxiliary door seal 110, dividing the interior of the auxiliary door seal 110 into a heating chamber 116 and an insulating chamber 118. The insulating chamber 118 is located close to the door body 120, and the heating chamber 116 is located on the side of the insulating chamber 118 away from the door body 120.
[0089] Heating elements 112 are disposed within heating chambers 116 and are evenly distributed along the length of auxiliary door seals 110, fitting tightly against the insulating element 114. Heating chambers 116 face the external environment or the junction of the two doors 120, while insulating chambers 118 face the interior of door bodies 120. The insulating element 114 prevents the heat generated by heating elements 112 from being transferred into the interior of door bodies 120, thus concentrating the heat on the surfaces of heating chambers 116 and auxiliary door seals 110, thereby improving anti-condensation efficiency.
[0090] The heating chamber 116 and the isolation chamber 118 are relatively independent spaces. The isolation element 114 fits tightly against the inner wall of the auxiliary door seal 110 without gaps, ensuring heat insulation. The wall of the heating chamber 116 is thinner than that of the isolation chamber 118, which facilitates heat transfer to the surface of the auxiliary door seal 110. The wall of the isolation chamber 118 is relatively thicker, which, together with the isolation element 114, further prevents heat loss.
[0091] The separator 114 separates the heating chamber 116 from the isolation chamber 118, so that the heat generated by the heating element 112 is concentrated on the surface of the auxiliary door seal 110 that needs to be prevented from condensing, avoiding the transfer of heat to the inside of the door body 120 and causing waste, greatly improving heating efficiency, reducing the energy consumption of the heating element 112, and at the same time rapidly increasing the surface temperature of the door seal, making the anti-condensation effect more significant.
[0092] The isolation chamber 118 and the isolation element 114 can block heat transfer to the door 120, prevent the door 120 from aging, deforming or peeling off due to long-term heat exposure, protect the structural integrity of the door 120, and extend the overall service life of the refrigeration equipment.
[0093] like Figure 1 and Figure 2 As shown, a second aspect of the present invention provides a door body 120, including the door sealing assembly as described above.
[0094] According to the second aspect of the present invention, the door 120 uses a door seal assembly to replace the traditional flip beam for sealing. No space is required inside the door 120 for the flip beam installation. Shelves and drawers are deeper, and bottle frames are widened to the edges, significantly increasing the volume ratio of the door 120 and allowing it to hold more items, meeting diverse storage needs and solving the problem of volume sacrifice caused by the flip beam in traditional door 120s. The flip beam-free design completely eliminates the noise of the flip beam during operation, making the door 120 quieter to open and close. The elastic material of the main door seal 100 and the thin-walled corner 108 design reduce deformation resistance. Combined with ordinary single and double-axis hinges, the door 120 closes smoothly automatically without additional force, making the opening and closing of the door 120 smoother. The multiple independent closed chambers 104 formed after the main door seal 100 deforms, together with the double seal of the flexible sealing parts at both ends and the auxiliary door seal 110, can effectively block the heat exchange between the inside and outside of the box, reduce convective heat transfer, and reduce the energy consumption of the refrigeration equipment; the heating element 112 of the auxiliary door seal 110 can prevent condensation from occurring, avoid condensation from affecting the sealing performance, and further ensure the stability of the heat insulation effect.
[0095] Please continue reading Figure 1 and Figure 2 The door 120 provided in the second aspect of the present invention achieves a non-flip beam seal by integrating the aforementioned door sealing components, thus balancing sealing performance and storage space.
[0096] The main door seal 100 is fixed to the inner liner or door shell of the door body 120 via the connecting plate 106: the side of the connecting plate 106 facing the door body 120 is tightly fitted to the surface of the door body 120 and fixed by bolts or adhesive, and the connection is firm and without looseness; the main door seal 100 protrudes from the surface of the door body 120, and its polygonal cross section faces the box body. When the door body 120 is closed, the main door seal 100 can form effective contact with the surface of the box body and the main door seal 100 of the other door body 120.
[0097] Because the door seal assembly eliminates the traditional flip beam, the internal cavity of the door 120 does not need to reserve space for the flip beam installation, allowing for an optimized layout of storage components: shelves can be designed as horizontal pull-out types, with a greater depth than traditional door 120, making full use of the space originally occupied by the flip beam; bottle frames can be widened to the edge of the door 120, increasing storage capacity; the depth of drawers is also increased accordingly, improving the volume ratio of the door 120. The installation of all storage components does not interfere with the deformation of the main door seal 100. When the door 120 is closed, the main door seal 100 can be smoothly compressed and deformed without colliding with shelves, bottle frames, etc.
[0098] The auxiliary door seal 110 is located on one side of a pair of door bodies 120, integrally formed with the main door seal 100, and together fixed to the edge of the door body 120. The heating element 112 inside the auxiliary door seal 110 is connected to the electrical system of the door body 120 via wires. The wires are hidden inside the door body 120 and do not affect the appearance or use of the door body 120. Flexible sealing elements are installed at both ends of the main door seal 100, tightly fitting against the end faces of the door body 120 to seal end gaps and ensure sealing integrity.
[0099] like Figure 1 and Figure 2 As shown, a third aspect of the present invention provides a refrigeration device, including the door seal assembly as described above; or, This includes the door 120 as described above.
[0100] According to the third aspect of the refrigeration equipment provided by the present invention, the refrigeration equipment achieves a beam-free seal through the door seal assembly, freeing up storage space in both the door 120 and the cabinet. The shelves and drawers of the door 120 are deeper, the bottle frames are wider, the cabinet cavity layout is more regular, and the overall volume ratio is significantly improved, meeting more storage needs of users and solving the problem of traditional French refrigerators sacrificing storage space due to the flip beam. The dual sealing design of multiple independent closed chambers 104 of the main door seal 100 and the auxiliary door seal 110 can effectively block the convection of hot and cold air, reduce cold loss, and reduce the operating load of the refrigeration system; the intelligent control of the heating element 112 avoids condensation from affecting the seal, further ensuring the heat insulation effect, and significantly reducing the energy consumption of the refrigeration equipment. The no-flip beam design completely eliminates the noise of the flip beam during operation, making the door 120 quieter to open and close; the elastic material of the main door seal 100 and the thin-walled corner design 108, combined with ordinary single and double axis hinges, make the door 120 close smoothly automatically without the need for additional force, improving the user's experience of opening and closing the door 120.
[0101] Please continue reading Figure 1 and Figure 2 The refrigeration equipment provided in the third aspect of the present invention achieves sealing without flip beam and high-efficiency refrigeration by integrating the aforementioned door sealing assembly or door body 120 with door sealing assembly.
[0102] A door seal assembly is fixedly installed on the side of the door 120 facing the enclosure. The main door seal 100 is arranged circumferentially along the edge of the door 120, and the connecting plate 106 is tightly fixed to the door 120. The auxiliary door seal 110 is located on the opposite side of the two doors 120. When the door 120 is closed, the main door seal 100 is pressed against the opening edge of the enclosure and the main door seal 100 of the other door 120, entering a deformed state to form a full circumferential seal. The auxiliary door seal 110 fits against the auxiliary door seal 110 of the other door 120, working together with the main door seal 100 to achieve a double seal.
[0103] The heating element 112 inside the auxiliary door seal 110 is electrically connected to the control system. The control system monitors the ambient temperature and humidity in real time. When it detects a risk of condensation on the door seal surface, it activates the heating element 112 to heat up and prevent condensation from occurring. The isolation element 114 blocks heat from being transferred to the door 120 and the interior of the cabinet, ensuring that the cooling efficiency of the refrigeration system is not affected.
[0104] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention.
