DETAILED DESCRIPTION



[0016] To make the foregoing objectives, features, and advantages of the present invention more comprehensible, the following describes in detail the specific embodiments of the present invention with reference to the accompanying drawings.

First embodiment



[0017] This embodiment provides a refrigerator. Referring to FIG. 1, the refrigerator includes a case body 10 enclosing a storage space, and a heat insulation wall 20 disposed within the storage space. The storage space is divided into mutually isolated storage compartments 10a by the heat insulation wall 20.

[0018] The storage compartment 10a may be any one of a refrigeration compartment, a variable temperature compartment, or a freezing compartment. In addition to a lateral arrangement manner in FIG. 1, adjacent storage compartments 10a may be vertically arranged. In addition, the number of the storage compartments 10a may be two or more.

[0019] Referring to FIG. 2 and FIG. 3, different from the prior art, the heat insulation wall 20 in this embodiment includes a vacuum glass module, and the vacuum glass module includes at least two glass layers 21 disposed at a spacing and a vacuum heat insulation cavity 22 located between adjacent glass layers 21. The two adjacent glass layers 21 are sealed at a peripheral edge by using a sealing element 23, to form the vacuum heat insulation cavity 22.

[0020] Therefore, the vacuum glass module is used for the heat insulation wall to perform heat insulation between the adjacent storage compartments. When heat insulation requirements are the same, the thickness of the vacuum glass module is significantly reduced compared with that of a heat insulation wall formed by means of foaming. In this way, space of the storage compartments can be enlarged and a storage capability of the refrigerator can be improved.

[0021] The heat insulation wall 20 formed by the vacuum glass module is supported within the storage space. There may be a variety of connection manners between the heat insulation wall 20 and the case body. For example, a frame 24 surrounding the glass layers 21 is disposed at a circumferential edge of the vacuum glass module and the vacuum glass module is supported on an inner wall of the case body 10 by using the frame 24.

[0022] To avoid leakage of cold air from the frame 24, a heat isolation space 24a may be provided within the frame 24, and the heat isolation space 24a may be full of air or be filled with a foaming heat insulation material. When the heat isolation space 24a is an air layer, the heat isolation space 24a is separated, in a direction surrounding the heat insulation wall 20, into a plurality of heat isolation spaces isolated from each other, to impair mobility of air within the frame 24 and improve the heat insulation performance of the frame 24.

[0023] Still referring to FIG. 3, the case body 10 further includes a support wall 11 extending towards the storage space, and the heat insulation wall 20 is supported on the support wall 11. Specifically, in a thickness direction of the heat insulation wall 20, the heat insulation wall 20 is disposed on a side of the support wall 11, and surfaces of the heat insulation wall 20 and the support wall 11 facing each other are connected by using an adhesive. The adhesive may be an adhesive material such as a hot melt adhesive or a double-sided adhesive tape.

[0024] When the heat insulation wall 20 is bonded into the support wall 11, the support wall 11 bears the weight of the heat insulation wall 20 as a load-bearing element. To avoid deformation of the support wall 11 during load-bearing, the support wall 11 may further be provided with a reinforcement plate 12 on a side towards the heat insulation wall 20, and be connected to the heat insulation wall 20 by using the reinforcement plate 12.

[0025] It should be noted that, in this embodiment, the support wall 11 is a part of the case body. A heat insulation space filled with a foaming heat insulation material is provided within the case body, and the heat insulation space extends into the support wall 11. That is, a heat insulation space is also provided within the support wall 11, and the heat insulation space is a part of the heat insulation space of the case body and is also filled with a foaming heat insulation material.

[0026] In another embodiment, the support wall may alternatively be an element independent of the case body. That is, the support wall and the case body are separately molded, and the support wall is fixedly connected to the case body.

Second embodiment



[0027] Referring to FIG. 4 and FIG. 5, a difference between this embodiment and the first embodiment lies in that structures of support walls are different. In this embodiment, the heat insulation wall 20 is provided with support walls 11 on both sides of a thickness direction, an insertion groove is formed between the support walls 11 on the two sides of the heat insulation wall 20, and the heat insulation wall 20 is inserted in the insertion groove between the support walls 11.

[0028] The connection manner between the heat insulation wall 20 and the support wall 11 is the same as that in Embodiment.

[0029] In other embodiments, the insertion groove may alternatively be recessed on the inner wall of the case body directly. That is, a support wall is not disposed on the inner wall of the case body 10 by extending towards the storage space. Instead, a groove is recessed on the inner wall of the case body 10 away from the storage space, a groove wall of the groove is used as a support wall, and the heat insulation wall is inserted in the groove and connected to the support wall.

[0030] Although the present invention is disclosed above, the present invention is not limited thereto. Any person skilled in the art may make various changes and modifications thereto without departing from the spirit or scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
