Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to an installation structure of a door body and a guide rail and a refrigerator. Background Art

[0002] At present, the refrigerator industry has French or American refrigerators with sheet metal guide rails on the door. After the door and body of such refrigerators are assembled and used for a few years, the connection between the door and the guide rail may be slightly deformed due to the door's own gravity, causing the top of the door to tilt outward and create a gap between the body and the door. For example, if the refrigerator body is on the right and the door is on the left, after a long period of use, the door will tilt to the left due to its own gravity and the support of the guide rail on the door, making it impossible for the door seal on the top of the door to completely seal the top of the opening side of the body, resulting in a serious risk of cold leakage and condensation inside the refrigerator.

[0003] Therefore the prior art still needs to be improved and enhanced. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a door and guide rail installation structure and a refrigerator, aiming to solve the problem that after the door and the cabinet of a French or American refrigerator in the prior art are assembled and used for a few years, the connection between the door and the guide rail may be slightly deformed due to the door's own gravity, causing the top of the door to tilt outward and create a gap between it and the cabinet, thereby making it impossible for the door seal on the top of the door to completely seal the top of the opening side of the cabinet, resulting in the risk of cold leakage and serious condensation in the refrigerator.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0008] In the present invention, a through groove is provided on the inner side of the door body, and the opening of the through groove is inclined upward with a small inclination angle, and one end of the guide rail is L-shaped. At the same time, the L-shaped end of the guide rail passes through the through groove and is connected to the foaming layer in the door body, and the L-shaped end of the guide rail is detachably connected or fixedly connected to the foaming layer. The detachable connection can be connected by bolts, and the fixed connection can be formed into one by wrapping the L-shaped end of the guide rail inside the foaming layer during the foaming process; the angle between the guide rail and the inner side of the door body is an acute angle, and the angle is close to 90°. When the door body is placed upright, the other end of the guide rail is at a higher horizontal height than the end of the guide rail connected to the through groove, that is, the guide rail gradually rises from the end close to the door body 1 to the end of the guide rail away from the door body, so that the gap between the top of the door body and the box body is smaller, and the door seal is arranged at the inner edge of the door body. The door seal is in the shape of a rectangular frame, and the four sides of the door seal respectively correspond to the four edges of the inner side of the door body. The door seal is detachably arranged on the door body and is used to seal the four edges of the opening side of the box body. By opening a through slot with an opening and an upward inclination on the inner side of the door body, the guide rail is tilted as a whole, and the angle between the guide rail and the door body is an acute angle. When the guide rail is horizontally installed in the refrigerator box body, at the beginning, the distance between the top end of the door body and the box body is smaller than the distance between the bottom end of the door body and the box body. At this time, the door seal at the top end of the door body and the door seal at the bottom end of the door body can both seal the opening side of the box body. After being used for a period of time, due to the gravity of the door body itself and the elasticity of the foam layer, the foam layer connected to the guide rail will be slightly deformed. At this time, the upper and lower ends of the door body are The difference in spacing between the end and the box body will be reduced, but the foam layer will no longer be deformed after being compressed to a certain extent, so that the spacing between the top end of the door body and the box body will not be greater than the spacing between the bottom end of the door body and the box body, thereby making the door seals at the top and bottom ends of the door body still able to seal the opening of the box body after long-term use, and no matter how long the refrigerator using the installation structure of the door body and the guide rail is used, the door seal on the door body of the refrigerator will always seal the refrigerator box body because the foam layer is compressed to a certain extent and no longer deforms, so as to prevent cold leakage from the box body and condensation in the box.

[0009] As a further improved technical solution, the above-mentioned installation structure of the door body and the guide rail further includes:

[0010] The embedded part is tiltedly arranged in the through groove, and one side of the embedded part is fixedly connected to the foaming layer in the door body, and one end of the guide rail is detachably connected to the other side of the embedded part.

[0011] The embedded part can be a plastic part or a metal part. The embedded part is arranged in the through groove and the side of the embedded part close to the guide rail is inclined upward. The side of the embedded part away from the guide rail is arranged in the door body and fixedly connected to the foaming layer, that is, the side of the embedded part away from the guide rail extends into the door body and is integrally formed with the foaming layer when the foaming layer is foamed, so as to improve the stability of the embedded part in the through groove. The side of the embedded part close to the guide rail is detachably connected to the guide rail, such as by clamping, bolting, etc., which is convenient for the later guide rail. maintenance or replacement of the guide rail; and after the door body has been used for a long time, due to its own gravity, the foam layer will be driven to tilt outward. At this time, the connection between the foam layer and the embedded part will be deformed, and the surrounding foam layer will be driven to deform slightly. When the foam layer is deformed to a certain extent, it will no longer be able to be compressed, and thus it will be fixed. At this time, the door seals at the top and bottom ends of the door body can still seal the opening of the box body, and after continued use, the door body will no longer continue to tilt. Therefore, the door seals on the door body of the refrigerator will always seal the refrigerator box body to prevent cold leakage and condensation in the box body.

At this time, the door seal 4 at the top end of the door body 1 and the door seal 4 at the bottom end of the door body 1 can both seal the opening side of the body. After being used for a period of time, due to the gravity of the door body 1 itself and the elasticity of the foam layer, the foam layer connected to the guide rail 3 will be slightly deformed. The difference in spacing between the upper and lower ends of the door body 1 and the box body will be reduced, but the foam layer will no longer deform after being compressed and deformed to a certain extent, so that the spacing between the top end of the door body 1 and the box body will not be greater than the spacing between the bottom end of the door body 1 and the box body, so that the door seals 4 at the top and bottom ends of the door body 1 can still seal the opening of the box body after long-term use, and no matter how long the refrigerator using the installation structure of the door body 1 and the guide rail 3 is used, the door seal 4 on the door body 1 of the refrigerator will always seal the refrigerator box because the foam layer is compressed to a certain extent and no longer deforms, so as to prevent cold leakage from the box and condensation of dew in the box.
