Description

Technical Field

[0001] This utility model relates to the field of refrigerator vertical beam technology, and in particular to a refrigerator vertical beam sealing structure. Background Technology

[0002] The refrigerator vertical beam sealing structure is a solution to improve the refrigerator's heat preservation effect. By adding a sealing design to the vertical beam part of the refrigerator, cold air leakage can be effectively reduced and the internal temperature can be kept stable. This structure usually uses high-density heat insulation materials and specific sealing strips to ensure that the refrigerator can maximize energy saving during operation and improve the overall refrigeration performance. This improvement not only helps to extend the food preservation time, but also improves the refrigerator's energy utilization efficiency.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing refrigerator vertical beam sealing structure cannot achieve buffering and deformation prevention, block cold air leakage, ensure sealing stability and compensate for closure errors. When closing the door, the lack of buffering can easily cause the sealing strip to deform excessively and crack, shortening its service life. It can also generate violent collision noise, increase the cold air leakage rate, require the refrigerator to frequently start and stop cooling, increase energy consumption, and cause large temperature fluctuations inside the refrigerator, affecting the preservation time of food. Without closure error compensation, gaps are easy to appear on the sealing surface, further aggravating air leakage. At the same time, condensate is easy to accumulate in the gaps, breeding mold and endangering food safety. In addition, the components are subjected to uneven stress over a long period of time, and the vertical beam, spring, etc. are easy to be damaged, increasing maintenance costs and reducing the overall reliability and user experience of the refrigerator.

[0004] Therefore, this utility model proposes a refrigerator vertical beam sealing structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a sealing structure for the vertical beam of a refrigerator.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a refrigerator vertical beam sealing structure, including a refrigerator, and further comprising:

[0007] An elastic buffer assembly includes a door mounted on a refrigerator, a vertical beam connected to the door, a fixed block connected to the vertical beam, a sliding block slidably connected inside the fixed block, a telescopic spring mounted on the sliding block, and a spring sheet connected to the sliding block.

[0008] A sealing assembly includes a sealing strip disposed on a spring sheet, a magnetic block connected to the side of the sealing strip away from the vertical beam, an auxiliary buffer cavity formed on the sealing strip, and a sealing cavity formed on the side of the sealing strip near the auxiliary buffer cavity. Both the auxiliary buffer cavity and the sealing cavity are filled with high-viscosity silicone-based sealing grease.

[0009] Furthermore, one end of the telescopic spring is connected to the fixed block, and the other end of the telescopic spring is connected to the sliding block.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: one end of the telescopic spring is connected to the fixed block and the other end is connected to the sliding block to form an elastic support. When the door is closed, the sliding block is squeezed and moves along the sliding cavity inside the fixed block, compressing the telescopic spring. The telescopic spring accumulates elastic potential energy and generates a rebound force, providing the sliding block with the reset power. At the same time, it works with the spring sheet to continuously apply pressure to the sealing strip, ensuring stable pressure on the sealing surface and compensating for the positional deviation when the door is closed.

[0011] Furthermore, the sealing strip has a groove, the width of which is adapted to the thickness of the spring sheet.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the groove width on the sealing strip is precisely matched with the thickness of the spring piece, and the two form a tight fit. During installation, the spring piece can be smoothly inserted into the groove, avoiding the sealing strip from shifting due to being too loose, or the assembly difficulty caused by being too tight. During the opening and closing of the door, the matching groove width can limit the lateral displacement of the sealing strip, ensuring that the sealing strip is always aligned with the sealing position and maintaining effective contact with the inner liner.

[0013] Furthermore, the inner wall of the card slot is coated with a food-grade adhesive layer, and one end of the spring piece is disposed inside the card slot.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the food-grade adhesive layer coated on the inner wall of the slot plays a bonding role after the spring is embedded. The adhesive layer enhances the connection strength between the spring and the sealing strip, preventing them from separating when the door is frequently opened and closed. At the same time, the food-grade material ensures safe use and does not release harmful substances. Furthermore, the adhesive's flexible properties allow it to stretch and contract slightly with the deformation of the sealing strip without affecting the elastic function of the sealing component.

[0015] Furthermore, the sealing strip contains EPDM rubber, which accounts for 70% of the sealing strip material, while silicone rubber accounts for 30%.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the sealing strip contains 70% EPDM rubber and 30% silicone rubber, which work together to optimize performance. EPDM rubber ensures the sealing strip's excellent weather resistance and anti-aging properties, adapting to the low-temperature environment inside the refrigerator. Silicone rubber improves the material's elasticity and sealing performance, making the sealing strip easy to deform and quick to rebound. The combination of the two makes the sealing strip both durable and able to fit tightly to the inner liner, reducing cold air leakage.

[0017] Furthermore, a honeycomb-shaped support block is provided inside the auxiliary buffer cavity.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the honeycomb support blocks in the auxiliary buffer cavity play a supporting and buffering role when the sealing strip is squeezed. The honeycomb structure can disperse the impact force of closing the door and prevent the auxiliary buffer cavity from collapsing excessively. At the same time, the gaps between the support blocks can accommodate high-viscosity sealing grease, guide the grease to be evenly distributed, enhance the buffering effect, and at the same time help block the cold air leakage channel and protect the stability of the sealing strip.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, when the door is closed, the magnetic block on the side of the sealing strip away from the vertical beam first attracts the refrigerator liner, initially positioning the sealing position. As the door continues to close, the sealing strip is compressed. The honeycomb support block in the auxiliary buffer cavity, together with high-viscosity silicone-based sealing grease, absorbs the impact force of closing the door, preventing excessive deformation of the sealing strip. The sealing grease in the sealing cavity adheres tightly to the liner, blocking the cold air leakage channel. At the same time, the sliding block in the fixed block on the vertical beam is compressed and moves along the sliding cavity, compressing the telescopic spring. The telescopic spring rebounds and generates a reverse force, which, together with the elastic deformation of the arc-shaped spring, provides a continuous and uniform clamping force for the sealing strip, compensating for the door closing error. When the door is opened, the magnetic block attraction is released, the telescopic spring pushes the sliding block to reset, and drives the spring and sealing strip back to their initial state, ensuring that the seal can still be stably sealed when closed next time. This achieves buffering to prevent deformation, blocking cold air leakage, ensuring a stable seal and compensating for closing errors. Attached Figure Description

[0030] 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.

[0031] like Figures 1-5 As shown, this embodiment provides a technical solution: a refrigerator vertical beam sealing structure, including a refrigerator 1, and further including:

[0032] The elastic buffer assembly 2 includes a door 21 installed on the refrigerator 1, a vertical beam 22 connected to the door 21, a fixed block 23 connected to the vertical beam 22, a sliding block 24 slidably connected inside the fixed block 23, a telescopic spring 25 installed on the sliding block 24, and a spring piece 26 connected to the sliding block 24.

[0033] The sealing assembly 3 includes a sealing strip 31 mounted on the spring piece 26. A magnetic block 32 is connected to the side of the sealing strip 31 away from the vertical beam 22. An auxiliary buffer cavity 35 is formed on the sealing strip 31, and a sealing cavity 36 is formed on the side of the sealing strip 31 near the auxiliary buffer cavity 35. Both the auxiliary buffer cavity 35 and the sealing cavity 36 are filled with high-viscosity silicone-based sealing grease 37. When the door 21 is closed, the magnetic block 32 on the side of the sealing strip 31 away from the vertical beam 22 first attracts to the inner liner of the refrigerator 1, initially positioning the sealing position. As the door continues to close, the sealing strip 31 is compressed, and the honeycomb support block 38 in the auxiliary buffer cavity 35, in conjunction with the high-viscosity silicone-based sealing grease 37, absorbs the impact force of closing the door. To prevent excessive deformation of the sealing strip 31, the sealing grease in the sealing cavity 36 tightly adheres to the inner liner, blocking the cold air leakage channel. At the same time, the sliding block 24 in the fixed block 23 on the vertical beam 22 is squeezed and moves along the sliding cavity, compressing the telescopic spring 25. The telescopic spring 25 rebounds and generates a reverse force, which, together with the elastic deformation of the arc-shaped spring 26, provides a continuous and uniform clamping force for the sealing strip 31, compensating for the door closing error. When the door is opened, the magnetic block 32's attraction force is released, and the telescopic spring 25 pushes the sliding block 24 to reset, causing the spring 26 and the sealing strip 31 to return to their initial state, ensuring that the seal can still be stably sealed when closed next time. This achieves buffering to prevent deformation, blocking cold air leakage, ensuring a stable seal and compensating for closing errors.

[0034] like Figure 4As shown, one end of the telescopic spring 25 is connected to the fixed block 23, and the other end of the telescopic spring 25 is connected to the sliding block 24. The telescopic spring 25 is connected to the fixed block 23 at one end and to the sliding block 24 at the other end, forming an elastic support. When the door 21 is closed, the sliding block 24 is squeezed and moves along the sliding cavity in the fixed block 23, compressing the telescopic spring 25. The telescopic spring 25 accumulates elastic potential energy and generates a rebound force, providing the sliding block 24 with the reset power. At the same time, it works with the spring piece 26 to continuously apply pressure to the sealing strip 31 to ensure stable pressure on the sealing surface and compensate for the positional deviation when the door is closed.

[0035] like Figures 3-5 As shown, the sealing strip 31 has a groove 33. The width of the groove 33 is adapted to the thickness of the spring piece 26. The groove 33 on the sealing strip 31 and the thickness of the spring piece 26 are precisely matched, forming a tight fit. During installation, the spring piece 26 can smoothly embed into the groove 33, avoiding the sealing strip 31 from shifting due to being too loose, or the assembly difficulty caused by being too tight. During the opening and closing of the door, the adapted groove width can limit the lateral displacement of the sealing strip 31, ensuring that the sealing strip 31 is always aligned with the sealing position and maintains effective adhesion with the inner liner. The inner wall of the groove 33 is coated with a food-grade adhesive layer. One end of the spring piece 26 is set in the groove 33. The food-grade adhesive layer coated on the inner wall of the groove 33 plays an adhesive role after the spring piece 26 is embedded. The adhesive layer enhances the connection strength between the spring piece 26 and the sealing strip 31, preventing them from separating when the door is frequently opened and closed. At the same time, the food-grade material ensures safety in use, does not release harmful substances, and the flexible properties of the adhesive can slightly stretch and contract with the deformation of the sealing strip 31 without affecting the elastic function of the sealing component. The sealing strip 31 contains EPDM rubber 34, which accounts for 70% of the material, while silicone rubber accounts for 30%. The sealing strip 31 contains 70% EPDM rubber 34 and 30% silicone rubber, which work synergistically to optimize performance. EPDM rubber 34 ensures excellent weather resistance and anti-aging properties, adapting to the low-temperature environment inside the refrigerator 1. Silicone rubber enhances the material's elasticity and sealing performance, making the sealing strip 31 easily deformable and quick to rebound. The combination of these two components makes the sealing strip 31 both durable and able to fit tightly against the inner liner, reducing cold air leakage. The auxiliary buffer cavity 35 contains honeycomb-shaped support blocks 38. These blocks provide support and cushioning when the sealing strip 31 is compressed. The honeycomb structure disperses the impact force of closing the door, preventing excessive collapse of the auxiliary buffer cavity 35. Simultaneously, the gaps between the support blocks can accommodate high-viscosity sealing grease, guiding its even distribution and enhancing the cushioning effect while also helping to block cold air leakage channels and protect the shape stability of the sealing strip 31.

[0036] Working principle:

[0037] like Figures 1-5As shown, when the door 21 is closed, in the sealing assembly 3, the magnetic block 32 on the side of the sealing strip 31 away from the vertical beam 22 first attracts the inner liner of the refrigerator 1, quickly and initially positioning the sealing position. As the door 21 continues to close, the sealing strip 31 is compressed, and the honeycomb support block 38 in the auxiliary buffer cavity 35 inside it cooperates with the high-viscosity silicone-based sealing grease 37 in the cavity. The honeycomb structure disperses the impact force of closing the door, preventing the auxiliary buffer cavity 35 from collapsing excessively, while the grease enhances the buffering effect. At the same time, the high-viscosity silicone-based sealing grease 37 in the sealing cavity 36 tightly adheres to the inner liner, directly blocking the cold air leakage channel. During this process, the elastic buffer assembly 2 plays a role. The sliding block 24 in the fixed block 23 on the vertical beam 22 is compressed and moves along the sliding cavity inside the fixed block 23, compressing the telescopic spring 25 that connects the fixed block 23 and the sliding block 24 at both ends. The telescopic spring 25 accumulates elastic potential energy and generates a rebound force. On the one hand, it provides power for subsequent reset, and on the other hand, it works with the elastic deformation of the arc-shaped spring 26 to provide continuous and uniform clamping force for the sealing strip 31, effectively compensating for the positional deviation when the door 21 is closed. The groove 33 on the sealing strip 31 is precisely matched with the thickness of the spring 26, limiting the lateral displacement of the sealing strip 31 and ensuring that it is always aligned with the sealing position. The food-grade adhesive layer on the inner wall enhances the connection strength between the spring 26 and the sealing strip 31 to prevent separation. The sealing strip 31 contains 70% EPDM rubber 34 and 30% silicone rubber. The former ensures weather resistance and anti-aging properties in low-temperature environments, while the latter improves elasticity and sealing performance, making the sealing strip 31 easy to deform and quick to rebound, tightly fitting the inner liner. When the door 21 is opened, the magnetic block 32 is released, the telescopic spring 25 releases elastic potential energy, pushes the sliding block 24 to reset, and drives the spring 26 and the sealing strip 31 back to their initial state, ensuring that the seal can still be stably sealed the next time it is closed.

[0038] 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.
