Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a door seal structure and a refrigerator. Background Technology

[0002] Refrigerator door seals typically contain magnetic strips, usually located within the seal and close to the refrigerator body, to adhere to and seal against the metal frame of the body. Anti-condensation tubes are generally installed within the refrigerator's frame. These tubes conduct heat from inside the refrigerator to raise the temperature around the door, thereby reducing condensation on the door surface.

[0003] However, since the magnetic strip is only present on the side near the cabinet, the heat transfer path of the anti-condensation tube is interrupted. The heat of the anti-condensation tube can only act on the side of the door seal near the cabinet through the magnetic strip, and cannot be effectively transferred to the door side. The outside of the door seal is still prone to condensation due to low temperature and contact with the outside humid air, which affects the user experience of the refrigerator. Moreover, long-term condensation will accelerate the aging and mold growth of the door seal, affecting the sealing performance and the service life of the refrigerator. Utility Model Content

[0004] Therefore, it is necessary to provide a door seal structure and refrigerator that can effectively reduce condensation on the outside of the door seal due to contact between low temperature and warm, humid air.

[0005] A door seal structure is provided for sealing the door and cabinet of a refrigerator. The cabinet has an anti-condensation tube inside. The door seal structure includes a door seal body and a magnetic component. The door seal body has a first wall, a second wall, and a third wall. The first wall is used to connect to the door body, the second wall is used to fit against the outer wall of the cabinet, and the third wall is located at the outer edge of the door seal structure and connects the first wall and the second wall. The magnetic component is installed inside the door seal body, and the outer surface of the magnetic component is respectively fitted against at least a portion of the third wall, the first wall, and the second wall.

[0006] In one embodiment, the door seal body further includes a first partition strip, with its two ends connected to a first wall and a second wall, respectively, and the first partition strip is spaced apart from a third wall. An assembly cavity is formed between the first partition strip, the third wall, at least a portion of the first wall, and at least a portion of the second wall, and the surface of the magnetic component is in contact with the wall of the assembly cavity. It is understood that this arrangement not only facilitates heat exchange between the magnetic component and the door seal body but also limits the position of the magnetic component, making it more securely installed inside the door seal body.

[0007] In one embodiment, along the direction from the first wall to the second wall, the cross-sectional area of ​​the magnetic component at both ends is larger than that at the middle. It is understood that this arrangement ensures that the magnetic component forms a heat transfer channel between the housing and the door, while also saving magnetic component material and reducing costs.

[0008] In one embodiment, along the direction from the first wall to the second wall, the magnetic component includes a first segment, a middle segment, and a second segment connected in sequence, with the two ends of the middle segment connected to the middle of the first segment and the middle of the second segment, respectively. It is understood that this arrangement not only improves the structural strength of the magnetic component but also allows the magnetic component to engage with the wall of the assembly cavity, thereby preventing the magnetic component from becoming loose inside the door seal body.

[0009] In one embodiment, along the length x of the refrigerator, the extension length of the second segment is greater than that of the first segment. It is understood that this arrangement facilitates the conduction of heat from the anti-condensation pipe through the second wall of the second segment.

[0010] In one embodiment, the door seal body also has multiple air bladder cavities inside. It is understood that the air bladder cavities serve for cushioning and heat insulation.

[0011] In one embodiment, the door seal body also includes a hook portion, one end of which is connected to the first wall, and the other end is suspended in the air. The suspended end of the hook portion is used to engage with the door body. It is understood that this design facilitates the installation of the door seal body onto the door body.

[0012] In one embodiment, a thermally conductive silicone pad is provided between the magnetic component and the first wall; and / or, a thermally conductive silicone pad is provided between the magnetic component and the second wall. It is understood that this arrangement prevents the supporting magnetic component from breaking due to repeated bending, and also facilitates heat conduction between the magnetic component and the door seal body.

[0013] A refrigerator includes a door, a cabinet, and a door sealing structure as described in any of the above embodiments.

[0014] In one embodiment, the enclosure includes a metal frame and a condensation-proof tube, the condensation-proof tube being located inside the metal frame, and the condensation-proof tube and the second wall being respectively attached to two opposite sides of the metal frame.

[0015] Compared with the prior art, the door seal structure and refrigerator provided in this application can form a heat transfer channel between the cabinet and the door when the door is closed. Specifically, the second wall is in contact with the cabinet, and the heat from the anti-condensation tube inside the cabinet can be transferred to the second wall and then to the magnetic component. The magnetic component further transfers the heat from the anti-condensation tube to the third wall and the second wall, thereby raising the temperature of the door seal body near the third wall to prevent condensation from forming on the third wall. In other words, it can prevent condensation from appearing on the outside of the door seal body, thereby improving the user experience. Attached Figure Description

[0025] Please see Figure 1 and Figure 2 This application provides a door seal structure 100 for sealing the door 200 and the cabinet 300 of a refrigerator. The cabinet 300 has an anti-condensation tube 320 inside. The door seal structure 100 includes a door seal body 110 and a magnetic component 120. The door seal body 110 has a first wall 111, a second wall 112 and a third wall 113. The first wall 111 is used to connect to the door 200, the second wall 112 is used to fit against the cabinet 300, and the third wall 113 is located at the outer edge of the door seal structure 100 and connects the first wall 111 and the second wall 112. The magnetic component 120 is installed inside the door seal body 110, and the outer surface of the magnetic component 120 is respectively fitted against at least a portion of the third wall 113, at least a portion of the first wall 111 and at least a portion of the second wall 112.

[0026] It should be noted that the third wall 113 is located at the outer edge of the door seal structure 100, meaning that the third wall 113 is located on the outer side of the door seal structure 100 along the length x direction of the refrigerator. When the door 200 is closed, the magnetic component 120 can form a heat transfer channel between the cabinet 300 and the door 200. Specifically, the second wall 112 is in contact with the cabinet 300, and the heat from the anti-condensation pipe 320 inside the cabinet 300 can be transferred to the second wall 112 and then to the magnetic component 120. The magnetic component 120 further transfers the heat from the anti-condensation pipe 320 to the third wall 113 and the second wall 112, thereby raising the temperature of the door seal body 110 near the third wall 113 to prevent condensation from forming on the third wall 113. In other words, it can prevent condensation from appearing on the outside of the door seal body 110, thereby improving the user experience.

[0027] The magnetic component 120 is configured to be made of a material with high thermal conductivity. For example, the magnetic component 120 is configured to be magnetic rubber with added metal powders such as aluminum powder and copper powder. This ensures that the magnetic component 120 can perform efficient heat transfer.

[0028] The door seal body 110 also has a first partition strip 114 inside. The two ends of the first partition strip 114 are respectively connected to the first wall 111 and the second wall 112, and the first partition strip 114 is spaced apart from the third wall 113. An assembly cavity 115 is formed between the first partition strip 114, the third wall 113, at least a portion of the first wall 111, and at least a portion of the second wall 112. The surface of the magnetic component 120 is in contact with the wall of the assembly cavity 115. In this way, not only is it beneficial for the magnetic component 120 to exchange heat with the door seal body 110, but it can also limit the magnetic component 120, so that the magnetic component 120 is more firmly installed inside the door seal body 110.

[0029] Optionally, in one embodiment, along the direction from the first wall 111 to the second wall 112, the cross-sectional area of ​​the magnetic element 120 at both ends is larger than that at the middle. This ensures that the magnetic element 120 forms a heat transfer channel between the housing 300 and the door 200 while saving material and reducing costs.

[0030] In one embodiment, the magnetic component 120, along the direction from the first wall 111 to the second wall 112, includes a first segment 121, a middle segment 123, and a second segment 122 connected in sequence. The two ends of the middle segment 123 are respectively connected to the middle portions of the first segment 121 and the second segment 122. That is, the cross-section of the magnetic component 120 is approximately "I"-shaped. This not only improves the structural strength of the magnetic component 120 but also allows the magnetic component 120 to engage with the wall of the assembly cavity 115, thereby preventing the magnetic component 120 from becoming loose inside the door seal body 110.

[0031] The first segment 121, the middle segment 123, and the second segment 122 are configured as a single structure.

[0032] Furthermore, the first segment 121 and the second segment 122 extend along the length x of the refrigerator, and the extension length of the second segment 122 is greater than the extension length of the first segment 121 along the length x of the refrigerator. Since the second segment 122 is located close to the second wall 112, by setting the extension length of the second segment 122 to be greater than the extension length of the first segment 121, it is convenient for the second segment 122 to conduct heat from the anti-condensation pipe 320 through the second wall 112.

[0033] Optionally, in one embodiment, the middle segment 123 is inclined relative to the front-rear direction y of the refrigerator. Alternatively, in other embodiments, the middle segment 123 may also extend along the front-rear direction y of the refrigerator.

[0034] The door seal body 110 also has multiple air bladder cavities 116 inside. The air bladder cavities 116 are used for cushioning and heat insulation. Specifically, the door seal body 110 has multiple spaced second partition strips 106 inside, which further divide the internal space of the door seal body 110 into multiple air bladder cavities 116.

[0035] In one embodiment, for example, one airbag cavity 116 is arranged side by side with the second segment 122 along the length x of the refrigerator, and the remaining multiple airbag cavities 116 are arranged on the right side of the middle segment 123 along the length x of the refrigerator.

[0036] The door seal body 110 is also provided with a hook portion 117. One end of the hook portion 117 is connected to the first wall 111, and the other end is suspended. The suspended end of the hook portion 117 is used to engage with the door body 200. Specifically, the door body 200 includes a door post 210 and a door inner liner 220 connected to each other. The magnetic component 120 abuts against the door post 210 through the first wall 111, and the hook portion 117 engages with the door inner liner 220.

[0037] The door seal structure 100 also includes a thermally conductive silicone pad, which is disposed between the magnetic component 120 and the first wall 111; or, the thermally conductive silicone pad is disposed between the magnetic component 120 and the second wall 112; or thermally conductive silicone pads are disposed between the magnetic component 120 and the first wall 111, and between the magnetic component 120 and the second wall 112. The thermally conductive silicone pad is used to support the magnetic component 120 and allow it to undergo elastic deformation when the door 200 is opened and closed, preventing the magnetic component 120 from breaking due to repeated bending, and also assisting in the conduction of heat between the magnetic component 120 and the door seal body 110.

[0038] This application also provides a refrigerator, which includes a door 200, a cabinet 300, and a door sealing structure 100 as described in any of the above embodiments.

[0039] Specifically, the enclosure 300 includes a metal frame 310 and an anti-condensation pipe 320. The anti-condensation pipe 320 is located inside the metal frame 310, and the anti-condensation pipe 320 and the second wall 112 are respectively attached to two opposite sides of the metal frame 310. The metal frame 310 can be made of iron sheet with good thermal conductivity.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
