Description

Technical Field

[0001] The utility model relates to the field of door seals, in particular to a novel refrigerator door seal. Background Art

[0002] Figure 3 and Figure 4 The refrigerator door seal currently used in the market is shown. Its structure includes a door seal connecting strip at the top, a fixed connecting pin is arranged at the top of the door seal connecting strip, a first short lip is extended inward from the inner side of the bottom of the door seal connecting strip, a second short lip is extended outward from the outer side of the bottom of the door seal connecting strip, an L-shaped lip extending inward is connected to the edge of the second short lip, and the first short lip, the second short lip and the L-shaped lip are combined to form a lip body with a chamber opening inward. This structure is simple and convenient to produce, but there is a problem, that is, in the entire lip body, the overall length of the L-shaped lip and the second short lip is relatively long, resulting in its weak strength. When the refrigerator door is closed, the deformation degree of the L-shaped lip is relatively large, which will greatly squeeze the airflow, and because its opening faces the inside and there is no obstruction, the process of the airflow being squeezed out is very smooth, resulting in a very easy generation of a whooshing sound of airflow when the refrigerator door is closed, which greatly affects the actual experience of users. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a refrigerator door seal which has higher strength and is less likely to generate airflow noise.

[0004] The utility model is a technical solution adopted to solve the problem: a novel refrigerator door seal, comprising a flexible door seal body;

[0005] The door seal body comprises a door seal bottom edge at the bottom, an outer door seal outer edge is arranged upwardly on the outer side of the door seal bottom edge, an inner door seal inner edge is arranged upwardly on the inner side of the door seal bottom edge, a door seal outer top edge extending toward the door seal inner edge is arranged on the top of the door seal outer edge, a door seal inner top edge extending toward the door seal outer edge is arranged on the top of the door seal inner edge, a first gap is formed between the door seal outer top edge and the door seal inner top edge, and the door seal bottom edge, the door seal outer edge, the door seal inner edge, the door seal outer top edge and the door seal inner top edge are enclosed to form an air chamber;

[0006] A plurality of exhaust notches extending to the outer surface of the outer side of the door seal are arranged at intervals on the outer top edge of the door seal, and an extended compensation platform facing the exhaust notches is arranged at the inner top edge of the door seal, and a fixed connecting pin is arranged on the top of the extended compensation platform;

[0007] A plurality of reinforcing ribs are arranged in the air chamber, and the reinforcing ribs are respectively connected to the inner side surfaces of the outer side edge of the door seal, the inner side edge of the door seal and the inner side surface of the bottom edge of the door seal.

[0008] As a further improvement of the above technical solution, the reinforcing rib is arranged directly below the extension compensation platform and connected to the lower surface of the extension compensation platform.

[0009] As a further improvement of the above technical solution, the bottom of the extension compensation platform is in the shape of an inclined platform, and the bottom of the extension compensation platform is connected to the inner wall of the inner side edge of the door seal.

[0010] As a further improvement of the above technical solution, the connection between the bottom edge of the door seal and the inner side edge of the door seal and the connection between the bottom edge of the door seal and the outer side edge of the door seal are both provided with inwardly concave rounded corners.

[0011] The beneficial effect of the utility model is that the fixed connecting pin is used to connect and fix with the box door, at this time, the surface of the outer top edge of the door seal and the inner top edge of the door seal are attached to the box door, and the first gap formed between the outer top edge of the door seal and the inner top edge of the door seal is attached to the box door. The side in contact with the box frame is the outer surface of the bottom edge of the door seal, and the two sides of the bottom edge of the door seal are respectively supported by the outer edge of the door seal, the outer top edge of the door seal, the inner edge of the door seal, and the inner top edge of the door seal, thereby making the bottom edge of the door seal have a stronger supporting force, and the reinforcing ribs in the air chamber play a role in strengthening the overall structure, so that the strength of the door seal body is further enhanced. When the box door is closed, the bottom edge of the door seal abuts against the surface of the box frame and squeezes the air chamber. During the squeezing process, the first gap will be further pressed against the box door, making it difficult for the air in the air chamber to be squeezed out along the first gap, thereby maintaining sufficient air in the air chamber for support, and the exhaust notch arranged on the outer edge of the door seal plays a role of conventional ventilation. When the box door is closed, the air in the air chamber can be slowly discharged through the exhaust notch. Through the above improvements, compared with the prior art, under the action of the same extrusion force, the product of this scheme has a smaller deformation in a short time, less exhaust volume, and is not prone to produce a large airflow sound.

[0021] Reference Figures 1 to 4 A novel refrigerator door seal comprises a flexible door seal body, wherein the door seal body comprises a door seal bottom edge 10 at the bottom, a door seal outer edge 30 is arranged upwardly on the outer side of the door seal bottom edge 10, a door seal inner edge 20 is arranged upwardly on the inner side of the door seal bottom edge 10, a door seal outer top edge 31 extending toward the door seal inner edge 20 is arranged at the top of the door seal outer edge 30, a door seal inner top edge 21 extending toward the door seal outer edge 30 is arranged at the top of the door seal inner edge 20, a gap is formed between the door seal outer top edge 31 and the door seal inner top edge 21, and the door seal bottom edge 10, the door seal outer edge 30, the door seal inner edge 20, the door seal outer top edge 31 and the door seal inner top edge 21 enclose an air chamber 11;

[0022] The outer top edge 31 of the door seal is provided with a plurality of exhaust notches 32 extending to the outer surface of the outer side edge 30 of the door seal, and the edge of the inner top edge 21 of the door seal is provided with an extended compensation platform 22 facing the exhaust notches 32, and a fixed connecting pin 50 is provided on the top of the extended compensation platform 22;

[0023] A plurality of reinforcing ribs 60 are disposed in the air chamber 11 , and the reinforcing ribs 60 are respectively connected to the inner side surfaces of the door seal outer edge 30 , the door seal inner edge 20 , and the door seal bottom edge 10 .

[0024] The fixed connecting pin 50 is used to connect and fix with the box door. At this time, the surface of the door seal outer top edge 31 and the door seal inner top edge 21 are attached to the box door, and the first gap 40 formed between the door seal outer top edge 31 and the door seal inner top edge 21 is attached to the box door. The side in contact with the box frame is the outer surface of the door seal bottom edge 10. The two sides of the door seal bottom edge 10 are respectively supported by the door seal outer edge 30 and the door seal outer top edge 31 as well as the door seal inner side edge 20 and the door seal inner top edge 21, so that the door seal bottom edge 10 has a stronger supporting force, and the reinforcing ribs 60 in the air chamber 11 play a role in strengthening the overall structure, so that the strength of the door seal body is further enhanced. When the box door is closed, the door seal bottom edge 10 abuts against the surface of the box frame and squeezes the air chamber 11. During the squeezing process, the first gap will be further The gap 40 is in close contact with the box door, so that the air in the air chamber 11 is difficult to be squeezed out along the first gap 40, thereby maintaining sufficient air in the air chamber 11 for support, and the exhaust notch 32 arranged on the outer edge 30 of the door seal plays a role of conventional ventilation.
