Description

Technical Field

[0001] This utility model relates to the field of refrigerator-related technology, and in particular to a refrigerator glass door. Background Technology

[0002] In existing refrigerators with cross-door, French door, and multi-door glass doors, to prevent problems such as loosening, leakage, and large gaps between the door cover and the glass after foaming, double-sided tape or sealant is usually applied to the glass-door mounting joint. However, this assembly method has the following significant drawbacks:

[0003] High operational difficulty: During the production process, it is necessary to manually apply double-sided tape or sealant between the glass and the door cover. This not only increases the production process but also raises the requirements for the workers' operating skills.

[0004] Unstable assembly quality: Due to factors such as worker operation and production errors, uneven bonding or wrinkling of the double-sided adhesive between the glass and the door cover is likely to occur, resulting in material leakage and large gaps after the door body is foamed, which affects product quality and may even lead to product scrap.

[0005] Low production efficiency: The process of applying double-sided tape or glue is time-consuming and it is difficult to ensure the consistency of assembly quality, which reduces production efficiency to some extent.

[0006] To overcome the above problems, it is necessary to improve the existing technology and propose a new type of refrigerator glass door assembly structure to improve assembly quality, production efficiency and product reliability. Utility Model Content

[0044] Example 1

[0045] Reference Figure 1 The first embodiment of this utility model provides a refrigerator glass door, including an upper door cover 100, a lower door cover 400, a door pillar 200, glass 300, a door liner 500, and a door seal 600.

[0046] Upper door cover 100: Its edge is provided with a first-step overflow structure 101, which is used to prevent the foam material from overflowing when the door body is foamed, and at the same time, the adhesiveness of the foam material is used to bond the upper door cover 100 to the glass 300.

[0047] Lower door cover 400: Its edge is provided with a second-step overflow structure 401, which has the same function as the first-step overflow structure 101, and is used to bond the lower door cover 400 to the glass 300.

[0048] Doorpost 200: Located between the upper door cover 100 and the lower door cover 400, glass 300 is located inside the doorpost 200, door liner 500 is located inside the glass 300, and door seal 600 is used for assembly with the foamed door body.

[0049] During assembly, the glass 300 is placed inside the doorpost 200, and the door liner 500 is installed close to the glass 300. The upper door cover 100 and the lower door cover 400 are pressed together by the stepped overflow structure to press the edge of the glass 300. After the foaming material is injected, the stepped overflow structure blocks the flow of the foaming material and makes it solidify and bond, forming an integral structure.

[0050] Example 2

[0051] Reference Figures 2-5 This is the second embodiment of the present invention, which differs from the above embodiments in that: based on embodiment 1, this embodiment further defines a stepped overflow structure.

[0052] The first-step overflow structure 101 includes a first-step surface 101a and a first overflow groove 101b. The first-step surface 101a is located at the edge where the upper cover 100 is assembled with the glass 300, and multiple sets of strip-shaped first overflow grooves 101b are spaced apart on the side near the glass 300 to accommodate excess foaming material.

[0053] The second-step overflow structure 401 includes a second-step surface 401a and a second overflow groove 401b, which are located at the assembly edge of the lower door cover 400 and the glass 300.

[0054] During the foaming process, the overflow trough can collect the overflowing foam material to prevent it from spilling and contaminating the door surface, while ensuring a tight fit between the stepped surface and the glass 300.

[0055] Example 3

[0056] Reference Figures 2-5 This is the third embodiment of the present invention, which differs from the previous embodiments in that: this embodiment adds a glue injection groove based on embodiment 2.

[0057] The first injection groove 101a-1 is recessed and located at the contact surface between the first stepped surface 101a and the glass 300, and is connected to the first overflow groove 101b, so that excess foaming material can flow into the overflow groove.

[0058] Second glue injection tank 401a-1: Located on the second stepped surface 401a, with the same function.

[0059] The grooved structure of the injection groove increases the contact area between the foam material and the door cover and glass 300, improving the bonding strength, while guiding the foam material to the overflow groove to avoid local accumulation.

[0060] Example 4

[0061] Reference Figures 2-5This is the fourth embodiment of the present invention, which differs from the previous embodiments in that: based on embodiment 3, this embodiment provides multiple sets of connecting ribs (such as wavy or strip-shaped protrusions, with strip-shaped protrusions being preferred in this embodiment) in the first injection groove 101a-1 and the second injection groove 401a-1. When the foaming material is injected, the connecting ribs increase the flow resistance and prolong the residence time of the foaming material. At the same time, the rib surfaces form mechanical interlocking, further enhancing the adhesion.

[0062] Example 5

[0063] Reference Figure 1 This is the fifth embodiment of the present invention, which differs from the previous embodiments in that: Based on Embodiment 1, this embodiment optimizes the arrangement of the doorposts 200: two sets of doorposts 200 are located on both sides of the glass 300, the door liner 500, and the door seal 600, respectively, with the upper and lower ends of the doorposts 200 embedded in the slots at the ends of the upper door cover 100 and the lower door cover 400. This design simplifies the assembly process; the doorposts 200 are fixed by snap-fit, eliminating the need for additional fasteners and improving the overall stability of the door.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
