The utility model discloses the refrigerator of implementing can adopt vapor compression refrigeration cycle system to refrigerate to provide cold volume. The vapor compression refrigeration cycle system includes a compressor, a condenser, an evaporator, a throttling device and other refrigeration accessories, and the detailed structure is not described herein.

Fig. 1 is a schematic view of a refrigerator inner container 10 and a rack 20 according to an embodiment of the present invention. The refrigerator includes an inner container 10, two rack support assemblies 30, and racks 20. The inner container 10 defines a storage space 101. The outer side of the inner container 10 may be further provided with a shell, and a foaming layer is formed between the shell and the inner container to jointly form a refrigerator body of the refrigerator. A door body can be installed at the front opening of the inner container 10.

The two rack support assemblies 30 are located inside the inner container 10 and are respectively mounted on the two lateral side walls 11, 12 of the inner container 10 for supporting the racks 20 inside the inner container 10. "mounted" herein means that the rack support assembly 30 is a separate component from the inner container 10 and is mounted to the lateral side walls of the inner container 10 after being manufactured. Of course, the rack support assembly 30 may be removed again after "installation". The two rack support assemblies 30 at both lateral sides of the inner container 10 constitute a set of rack support assemblies 30.

The rack 20 is located inside the liner 10 for carrying articles. The rack 20 may be integrally plate-shaped. The two lateral edges of the rack 20 are supported by the two rack support assemblies 30, respectively.

It is understood that a plurality of groups of rack support assemblies 30 with different heights may be installed inside the inner container 10 for supporting a plurality of racks 20, and the height position of a certain rack 20 may be adjusted.

The embodiment of the present invention designs a rack supporting assembly 30 independent of the inner container 10. In the manufacturing process of the refrigerator, the rack supporting assembly 30 is installed on the lateral side wall of the inner container 10 according to different requirements of different models of refrigerators on the height of the rack 20. Therefore, the inner container 10 is not required to be provided with a support rib structure, so that the processing mold of the inner container 10 is simpler and has lower cost. In addition, for the improved type product which only adjusts the layout of the article placing device, the inner container 10 does not need to be redesigned, and the larger cost expense caused by the mold opening of the inner container 10 again is avoided.

Also, since the rack support assembly 30 is installed at the inner container 10 at a later stage, an assembler can install it at any height of the inner container 10. The user may also detach the rack support assembly 30 and change its mounting position if desired. In summary, it is very convenient for a designer or a user to adjust the layout of the rack support assemblies 30 (including the position of a certain rack support assembly 30 and the distance between two adjacent rack support assemblies 30) in the inner container 10, thereby adjusting the layout of the rack devices in the entire refrigerator.

FIG. 2 is a schematic structural view of the rear support 100 in the rack support assembly 30 of FIG. 1; FIG. 3 is a schematic view of the rear support 100 and rack 20 shown in FIG. 2; fig. 4 is a schematic diagram of the front support 200 of the rack support assembly 30 of fig. 1.

As shown in fig. 1-4, a rack support assembly 30 according to an embodiment of the present invention may generally include a rear support 100 and a front support 200.

The rear supporter 100 is adapted to be mounted at any position of one lateral sidewall of the inner container 10 so as to support the rear of the lateral edge of one or more racks 20. The rear supporter 100 can be installed at an "arbitrary position" of the lateral side wall of the inner container 10 because any connection structure for connecting the rear supporter 100 is not designed on the lateral side wall of the inner container 10. An operator can select any suitable position according to the requirement and then fasten the rear support 100 at the position. For example, it may be glued or screwed. If the screw connection is adopted, the inner container 10 does not need to be perforated during processing, and after the supporting piece 100 is installed and the position is selected, the hole is perforated. Or, the position is selected without drilling, and the tapping screw is directly adopted.

The front support 200 is adapted to be mounted to one lateral side wall of the inner container 10 and is positioned in front of the rear support 100 so as to support the front of the lateral edge of one or more racks 20. As with the rear support 100, the specific installation position of the front support 200 is also selected at a later stage, and the specific installation manner may be adhesion or screw connection, which is not described in detail.

The inventors have found that the prior art utilizes the support bars to support the entire lateral edge of the rack 20, forming a wire-like support structure. Once the edge of the rack 20 is slightly deformed, some areas of the support ribs cannot contact the rack 20, which results in weak support and "virtual support", and unstable position of the rack 20. In the embodiment of the present invention, the front support 200 and the rear support 100 are only arranged in tandem and close to the lateral edges of the two-point support rack 20, and the two-point support structure does not generate "virtual support" to stabilize the position of the rack 20.

As shown in fig. 2 and 3, a surface of the rear support 100 facing the lateral edge of the rack 20 (for example, for the rear support 100 disposed at the right lateral side wall 12 of the inner container 10, the "surface" refers to the left side surface of the rear support 100) is inwardly opened with a catch groove 110 to allow the rack 20 to be inserted therein from front to rear for receiving and supporting the lateral edge of the rack 20. That is, the lateral edges of the rack 20 are supported by the bottom wall of the card slot 110. Of course, it is also possible to provide the surface of the rear supporter 100 with the outwardly extending protrusions 22 to support the lateral edges of the rack 20, as in the prior art. However, the pressure-bearing capacity of the protruding portion 22 on the object surface is obviously inferior to the structure of the slot 110 formed by the object surface being concave.

Further, as shown in fig. 3, the rear portion of the bottom wall of the locking slot 110 may be recessed downward to form an inner recess 112 for accommodating the downward protruding protrusion 22 at the bottom of the rear edge of the rack 20. This restrains the degree of freedom of the rack 20 in the front-rear direction, and makes the position of the rack 20 more stable.

The inventor has recognized that the rear portion of the rack 20 is inserted backward into the catching groove 110 of the rear support 100 when the rack 20 is mounted, and this backward insertion mounting is not suitable for the front support 200. Therefore, the front supporter 200 may be designed as a simpler supporting structure to support only one rack 20, and has a simple structure and a more compact appearance without interfering with the backward insertion operation of the rack 20 into the rear supporter 100. In addition, since the rear supporter 100 is provided with the slot 110, if the overall volume is too small, providing a relatively large slot (at least enough to accommodate the edge of the rack) may not ensure strength. Therefore, the rear support 100 can be designed to be larger, so that more slots 110 are formed, thereby not only having more rack mounting positions, but also enabling each slot 110 to be supported by one larger rear support 100, so that the carrying capacity is stronger.

In view of the above, as shown in fig. 1 to 4, it is preferable that the number of the card slots 110 is plural, and the plural card slots 110 are arranged at intervals in the vertical direction. The number of the front supports 200 is equal to the number of the locking slots 110, and each front support 200 is used for supporting one rack 20. One rear support 100 is matched to a plurality of front supports 200.

As shown in fig. 2, the rear supporter 100 may be formed in a cover-shell shape, which is fastened to the lateral side wall of the inner container 10, and has a peripheral edge smoothly connected to the surface of the lateral side wall of the inner container 10 and a central area bulging outward to form a catching groove 110. This makes the connection between the rear supporter 100 and the lateral side wall of the inner container 10 smoother, thereby preventing the rack 20 from being damaged when the rack 20 is accidentally bumped against it. The upper and lower ends of the rear supporter 100 are respectively opened with screw holes 120 so that the rear supporter 100 is fastened to the lateral side wall of the inner container 10 by screws.

As shown in fig. 4, the front supporter 200 may have a long casing shape with a length direction parallel to the front and rear directions, and may be fastened to the lateral sidewall surface of the inner container 10, and have a circumference smoothly connected to the lateral sidewall surface of the inner container 10, and a center thereof is protruded outward from the front and rear ends so as to support the rack 20 upward. This makes the connection between the front support 200 and the lateral side wall of the inner container 10 smoother, thereby preventing the rack 20 from being damaged when the rack 20 is accidentally bumped against it. Screw holes 210 are respectively formed at front and rear ends of the front supporter 200 so that the front supporter 200 is fastened to the lateral side wall of the inner bag 10 by screws.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
