Description

Technical Field

[0001] The utility model relates to the technical field of freezer manufacturing, and particularly relates to a simple structure of a reinforcing plate for preventing creases on the inner bile duct of a freezer. Background Technique

[0002] The inner liner of a traditional freezer ( Figure 3 as shown).

[0003] In the existing inner liner structure of a freezer, the wall thickness of the metal inner liner is relatively thin, and in order to increase the aesthetics, the four corners of the freezer inner liner are made with relatively small rounded corners, about R8 - R15. When the inner liner is assembling the return air pipe, since the return air pipe is assembled by means of machine automatic pipe winding, two problems are caused: one is that the thin metal panel of the inner liner results in pipe creases at the four corners, affecting the appearance of the product; the other problem is that the small rounded corners at the corners make it easy to have defects such as pipe cracking or creasing during the pipe winding of the return air pipe, affecting the reliability of the refrigeration system. To solve the above problems, the traditional method is to solve them in the following ways: one is to increase the thickness of the inner liner plate to increase the anti-deformation ability, which significantly increases the cost of the inner liner; the other is to increase the rounded corners of the four corners to reduce the extrusion deformation force, which can solve the problems of pipe creases and pipe cracking or pipe creasing defects, but the inside of the freezer looks round and bulging, affecting the appearance. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the above background technique, and to propose a simple structure of a reinforcing plate for preventing creases on the inner bile duct of a freezer.

[0007] As a further scheme of the utility model: the arc transition surface at the connection of the two corresponding right-angled surfaces is a chamfered corner.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1, please refer to Figure 1-2 As shown, the present utility model is a simple structure of a reinforcing plate for preventing tube creases in the inner liner of a freezer, including an inner liner 1. It is characterized in that reinforcing plates 3 are attached to the four corners of the inner liner 1. The reinforcing plate 3 includes two right-angle surfaces corresponding to each other at 90 degrees, and the two right-angle surfaces are fixed to each other. The connection at the middle of the two corresponding right-angle surfaces is in an arc transition.

[0022] Embodiment 2, please refer to Figure 1-2As shown in the figure, the utility model is a simple structure of a reinforcing plate for preventing creases on the inner bile duct of a freezer, including an inner liner 1. It is characterized in that reinforcing plates 3 are attached to the four corners of the inner liner 1. The reinforcing plate 3 includes two right-angled surfaces corresponding at 90 degrees, and the two right-angled surfaces are fixed to each other. The connection at the middle of the two corresponding right-angled surfaces is in an arc transition.

[0023] The arc transition surface at the connection of the two corresponding right-angled surfaces is a rounded corner.

[0024] The rounded corner is R10 - R15.

[0025] Example three, please refer to Figure 1-2 As shown in the figure, the utility model is a simple structure of a reinforcing plate for preventing creases on the inner bile duct of a freezer, including an inner liner 1. It is characterized in that reinforcing plates 3 are attached to the four corners of the inner liner 1. The reinforcing plate 3 includes two right-angled surfaces corresponding at 90 degrees, and the two right-angled surfaces are fixed to each other. The connection at the middle of the two corresponding right-angled surfaces is in an arc transition.

[0026] The arc transition surface at the connection of the two corresponding right-angled surfaces is a rounded corner.

[0027] The rounded corner is R10 - R15.

[0028] The distance between the top of the reinforcing plate 3 and the bile opening at the top of the inner liner 1 is 30 mm.

[0029] The reinforcing plate 3 is adhesively fixed to the inner liner 1 through tape.

[0030] The width of the right-angled surface of the reinforcing plate 3 is 8 - 18 mm.

[0031] It is worth adding that:

[0032] The corners of the inner liner of the freezer of the utility model are strengthened by using a reinforcing plate to improve the anti-deformation ability of the corners.

[0033] The reinforcing plate 3 is designed as a thin metal plate. The reinforcing plate 3 is composed of a circular arc surface and two straight planes. The cross-section of the reinforcing plate 3 is simple, reducing the mold cost.

[0034] The reinforcing plate 3 can be continuously produced automatically by an extrusion die, improving the production efficiency. With an extrusion automatic production line, the lengths of the four corner reinforcing plates 3 can be determined according to the size of the product by itself without re-opening the mold, saving the mold opening cost for different lengths of the reinforcing plate 3.

[0035] The rounded corner of the reinforcing plate 3 is designed as a R10 - R15 rounded corner, solving the defects such as tube creases caused by small rounded corners designed for appearance in the existing structure and cracking or wrinkling when the return air pipe 2 is wound around the pipe.

[0036] The linear plane width of the reinforcement plate 3 is designed to be 8 - 18 mm to save the material cost of the reinforcement plate 3.

[0037] The upper end of the reinforcement plate 3 is about 30 mm away from the bile port. One function is to avoid the face frame assembled at the upper end of the inner liner bile port to prevent interference. Another function is to reduce the length of the reinforcement plate 3 to save material cost. The same applies to the lower end.

[0038] The length of the reinforcement plate 3 is determined according to the winding height of the return air pipe 2. The upper and lower ends of the reinforcement plate 3 extend beyond the return air pipe by 10 - 20 mm to increase the contact area when assembling the return air pipe at the upper and lower ends, improve the anti-deformation ability, and at the same time prevent the return air pipe 2 from winding empty and generating crease defects when winding to the outer surface of the inner liner 1.

[0039] The assembly method of the reinforcement plate 3 is fixed by tape, and the structure of fixing with adhesive sponge is cancelled. While reducing the part cost, if the position of the reinforcement plate 3 is fixed incorrectly, it can be quickly repaired to improve the maintenance efficiency.

[0040] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the claims of the present invention.
