Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to a sealing strip anti-frost structure for a refrigerator. Background Art

[0002] The freezer anti-frost seal, also known as the freezer door seal or freezer seal, is a sealing device installed on the edge of the freezer door. Its main function is to ensure that the internal temperature of the freezer is isolated from the external environment, reduce the loss of cold air, save energy, and prevent moisture in the external air from entering the freezer to reduce frost.

[0003] When the freezer door is closed, the sealing strip forms a tightly closed state, effectively preventing water vapor from the outside air from entering the freezer. Since the temperature inside the freezer is lower than that outside, moisture in the air tends to condense into frost quickly after entering. The presence of the sealing strip can reduce the entry of this moisture, thereby reducing frost.

[0004] The sealing performance of the existing refrigerator sealing strips gradually weakens during use, causing water vapor in the air to easily enter the refrigerator, thereby forming frost. Although some refrigerators are equipped with defrosting functions, the effect is not good, and the frost layer is still thick, requiring regular manual defrosting. The design problem of the refrigerator sealing strips causes water vapor in the air to easily enter the refrigerator. At the same time, some sealing strips are more complicated to install and are not convenient for users to replace by themselves.

[0005] Therefore, it is necessary to invent a sealing strip anti-frost structure for a refrigerator to solve the above problems. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-5 The sealing strip anti-frost structure for a refrigerator shown in the figure comprises a shell 1, a sealing strip 2 is arranged on the front of the shell 1, the sealing strip 2 adopts a U-shaped connecting portion 21, which enhances the sealing performance, prevents water vapor in the air from entering the interior of the refrigerator, and reduces frost. A heating strip 3 is arranged inside the shell 1, and the sealing strip 2 is engaged with the front of the shell 1. The sealing strip 2 of this structure has good sealing performance, which can effectively reduce the loss of cold air and reduce energy consumption.

[0025] The base layer of the sealing strip 2 is a connecting portion 21, a supporting portion 22 is arranged on the front of the connecting portion 21, at least one horizontal bar is arranged inside the supporting portion 22, the inside of the supporting portion 22 is divided by the horizontal bar, a buffer portion 23 is arranged on the front of the supporting portion 22, the buffer portion 23 is composed of a plurality of triangular hollow structures, the plurality of hollow triangles of the buffer portion 23 are evenly distributed, and the spacing between each hollow triangle is not less than five millimeters, and the design of the plurality of triangular hollow buffer portions 23 can effectively buffer the opening and closing of the refrigerator door.

[0026] Furthermore, in the above technical solution, the connecting part 21 has a U-shaped structure, and clamping strips 25 are fixedly installed on both sides of the back side of the connecting part 21, and two protrusions 24 are fixedly installed on the outer side of each clamping strip 25. There is a gap between the clamping strip 25 and the side of the connecting part 21, and the two side edges of the shell 1 are engaged in the gap between the clamping strip 25 and the connecting part 21.

[0027] Furthermore, in the above technical solution, two card grooves 11 are provided on the inner walls of the two side edges of the shell 1, and the two card strips 25 are located on the inner sides of the two side edges of the shell 1. The card strips 25 and the raised parts 24 are both made of rubber material, which has good wear resistance and anti-aging performance, thereby improving the service life of the sealing strip, and the back side of the connecting part 21 does not contact the heating strip 3.

[0028] Furthermore, in the above technical solution, a mounting seat 12 is fixedly installed in the middle position of the top of the shell 1, and a through hole is vertically opened in the mounting seat 12. The upper end of the heating strip 3 passes through the through hole of the mounting seat 12 and is fixed by bolts.

[0029] Furthermore, in the above technical solution, a heat insulating strip 4 is fixedly installed on the front inner wall of the shell 1, and a plurality of evenly distributed springs 5 ​​are laterally fixedly installed on the front of the heat insulating strip 4. The front end of each spring 5 is connected to the back side of the connecting portion 21 of the sealing strip 2. The springs 5 ​​support the back side of the connecting portion 21 to prevent the cabinet door from hitting the connecting portion 21 when opening and closing, causing the connecting portion 21 to collapse and unable to return to its original shape normally, thereby affecting the sealing effect of the sealing strip 2.

[0030] The utility model provides a sealing strip anti-frost structure for a refrigerator, and its working process is as follows when in use:

[0031] At the edge of the refrigerator door, install the sealing strip 2 on the front of the shell 1. Make sure that the sealing strip 2 fits tightly against the edge of the refrigerator door to form a good sealing effect. The U-shaped connecting portion 21 of the sealing strip 2 enhances the blocking effect against cold air. When the refrigerator door is closed, the sealing strip 2 and the shell 1 form a tightly closed state, effectively blocking water vapor in the external air from entering the interior of the refrigerator. Since the base layer of the sealing strip 2 is the connecting portion 21, a supporting portion 22 and at least one horizontal strip are provided inside it, so that the supporting performance is better. During the opening and closing process of the refrigerator door, the buffer portion 23 of the sealing strip 2 (composed of a plurality of triangular hollow structures) can effectively buffer the opening and closing of the refrigerator door and reduce the friction between the door gaps.

[0032] The housing 1 is provided with a heating strip 3. When the temperature inside the refrigerator is lower than that outside, the heating strip 3 can increase the temperature of the sealing strip 2, making it less likely to frost. The heating strip 3 starts to work after being powered on, heating the sealing strip 2 and the surrounding area, maintaining a certain temperature and reducing the possibility of frost. The function of the insulation strip 4 and the spring 5 is to keep the sealing strip 2 in a taut state, improve the sealing performance, and prevent water vapor in the air from entering the refrigerator. Due to the effective sealing of the sealing strip 2 and the function of the heating strip 3, the water vapor inside the refrigerator will not quickly condense into frost, reducing the frosting phenomenon.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
