Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, and in particular to a refrigerator door body. Background Art

[0002] Large-capacity refrigerators are becoming more and more popular with users. As the size of refrigerators increases, the refrigerator door will also become larger accordingly, especially for large double-door upright refrigerators. The larger the refrigerator door, the easier it is to deform. The deformation of the refrigerator door may lead to a series of adverse consequences. The deformation of the refrigerator door will cause the door to be unable to close tightly, thereby affecting the sealing of the refrigerator, causing warm and humid air in the room to enter the refrigerator, which may cause problems such as icing in the cabin and loud noise. Poor sealing will also cause cold air to leak out, and the temperature in the refrigerator may not reach the preset value, causing the compressor to continue working for a long time, which will not only increase energy consumption, but also may generate high temperature, causing the compressor to overheat or even damage. In addition, the deformation of the refrigerator door may also affect the overall appearance and user experience of the refrigerator, causing inconvenience to users. In view of this, it is necessary to improve the existing technology. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 to Figure 2As shown, a preferred embodiment of the utility model provides a refrigerator door body, which includes an outer shell 1 and an inner container that are opposite to each other front and back.

[0023] The top of the outer shell 1 and the inner liner 2 are connected by an upper end cover 3, specifically by welding or bolting. The bottom of the outer shell 1 and the inner liner 2 are connected by a lower end cover 4, specifically by welding or bolting. The left side of the outer shell 1 is bent inward by 90° to form a left frame 5, and the left end of the outer shell 1 and the inner liner 2 are connected by the left frame 5, specifically by welding or bolting. The right side of the outer shell 1 is provided with a flange, and the flange is connected to the right end of the inner liner 2 by a right frame 6, specifically by welding or bolting.

[0024] The outer shell 1, the inner shell 2, the upper end cover 3, the lower end cover 4, the left frame 5 and the right frame 6 surround and form a foaming cavity, and the foaming cavity is filled with a foaming layer.

[0025] The inner side of the left frame 5, i.e., the side located in the foaming cavity, is fixedly provided with a left reinforcing rib plate 7 along the length direction of the left frame 5. The length of the left reinforcing rib plate 7 is 60%-80% of the length of the left frame 5, and is 75% in this embodiment. The left reinforcing rib plate 7 is made of metal, and is made of iron in this embodiment. The left frame 5 and the left reinforcing rib plate 7 can be fixedly connected by welding, bolts or gluing.
