Hereinafter, the present invention will be described in detail with reference to the accompanying drawings for a side-by-side type refrigerator having a shelf having a sliding shelf having a variable structure as an example of the present invention.

However, it is a matter of course that the present invention can be applied to general shelves instead of the structure change. In addition, the present invention may also be applied to shelves arranged in various types of refrigerators, such as the TMO (TOP MOUNTED FREEZER) type other than the side by side type.

As shown in FIG. 1, the refrigerator 1 according to the present invention includes a main cabinet 2 in which a storage compartment 3 is formed, and a shelf 10 partitioning the storage compartment 3 into a plurality of spaces.

The main cabinet 2 includes an outer casing 2a that forms the exterior of the refrigerator 1 and an inner casing 2b that forms the storage compartment 3. In addition, a door 4 for opening and closing the storage compartment 3 is rotatably coupled to the main body cabinet 2. Here, the shelf 10 for dividing the storage compartment 3 into a plurality of spaces may be arranged in two types, the structure of which can be changed and the structure thereof is not.

2 to 4, the shelf 10 according to the present invention is a shelf frame 20 for partitioning the storage compartment 3 of the main body cabinet 2, a panel 30 on which the article is supported, It includes a support frame 40 detachably coupled to the shelf frame 20 and accommodates the panel 30, and a sliding shelf portion 50 that is slidably coupled to the shelf frame 20.

The shelf frame 20 may be arranged in plural to partition the storage compartment 3 into a plurality of spaces as described above. Shelf frame 20 is made of a material having a larger coefficient of thermal expansion than the panel to be described later. On the other hand, the shelf frame 20 is a receiving portion 21, the support frame 40 to be described later, the insertion portion 22 is inserted into one region of the support frame 40, the support frame 40 is seated And a support part 23 to be supported, and a fixing part 24 and a protrusion accommodating part 25 to prevent the support frame 40 from being separated so that the coupled support frame 40 is not separated. Here, according to the present invention further includes an extension part 27 provided in a pair of shelf frames 20 and having a guide 26 for guiding the movement of the sliding shelf part 50 to be described later.

The accommodating part 21 is formed to be opened in the shelf frame 20. Receiving portion 21 is formed recessed than the height of the support frame 40 so that the support frame 40 coupled during the assembly process is not higher than the plate surface of the shelf frame 20. That is, the support frame 40 accommodated in the accommodating portion 21 is prevented from being raised above the plate surface of the shelf frame 20 by thermal expansion.

The insertion part 22 is formed at one side of the circumference of the accommodation part 21 so that one region of the support frame 40 coupled to the accommodation part 21 is inserted. That is, the insertion portion 22 is an example of the present invention, the sliding shelf 50 is formed in the circumferential length direction of the adjacent receiving portion 21.

The support part 23 protrudes from the periphery of the accommodating part 21 except the insertion part 22 mentioned above. The support part 23 is provided so that the support frame 40 coupled to the insertion part 22 is seated and supported by the receiving part 21.

Fixing portion 24, as shown in Figure 5, to prevent the support frame 40 coupled to the shelf frame 20 is separated. The fixing part 24 is an example of the present invention, and protrudes around the circumferential lengthwise direction of the accommodating part 21 in which the insertion part 22 is formed. As one example of the present invention, three fixing portions 24 are formed, but may be formed to protrude to less than three or more than three.

The protrusion accommodating part 25 is provided in the shelf frame 20 corresponding to the protrusion 41 of the support frame 40 which will be described later. As an example of the present invention, the protrusion accommodating part 25 is formed in the circumferential transverse direction of the accommodating part 21 in which the aforementioned insertion part 22 and the fixing part 24 are not formed. That is, the protrusion accommodating part 25 prevents the protrusion 41 of the support frame 40 from being inserted to move the support frame 40 horizontally in the accommodating part 21.

The extension part 27 is formed to protrude from the area where the shelf frame 20 and the support frame 40 are coupled. The extension part 27 is provided in a pair so that the sliding shelf part 50 is coupled. On the other hand, the extension portion 27 is provided with a guide 26 guides the sliding shelf 50 to be slidably moved to the lower portion of the support frame 40.

The panel 30 is provided so that articles stored in the shelf 10 are seated. Panel 30 is an example of the present invention, but made of a glass material, it may be made of a material such as synthetic resin. However, the panel 30 is preferably made of a glass material in order to enhance the interior of the storage compartment 3. As an example of the present invention, the panel 30 made of glass material has a smaller coefficient of thermal expansion than the shelf frame 20. That is, since the shelf frame 20 has a large coefficient of thermal expansion according to the temperature change, the expansion and contraction of the shelf frame 20 occurs, but the panel 30 hardly changes the expansion and contraction.

The support frame 40 is detachably coupled to the shelf frame 20 and is provided to accommodate the panel 30. The support frame 40 is formed along the circumference of the panel 30. Protrusions 41 are provided on both sides of the support frame 40 in the horizontal direction so as to prevent the support frame 40 from flowing horizontally in correspondence with the above-described protrusion accommodating portion 25.

On the other hand, the support frame 40 is an example of the present invention, by inserting the injection molding together with the panel 30 is produced integrally. The support frame 40 is made of a material having the same coefficient of thermal expansion and strength as the shelf frame 20 as an example of the present invention. On the other hand, the support frame 40 is made of a material having a higher strength than the shelf frame 20 can be complementary to the strength when coupled to the shelf frame 20.

Here, the above-described shelf frame 20 and the support frame 40 are coupled at a distance δ corresponding to the expansion rate of the support frame 40. By combining the shelf frame 20 and the support frame 40 with a gap δ, the amount of change due to thermal expansion of the shelf frame 20 and the support frame 40 is offset.

Looking at the assembly process of the shelf 10 according to the present invention by such a configuration as follows.

The shelf frame 20 which forms the main body of the shelf 10 which partitions the storage compartment 3 is produced. The panel 30, in which the article is stored and supported, is made of glass, and the panel 30 made of glass is manufactured by integrating the panel 30 and the support frame 40 by insert injection of the support frame. The support frame 40 and the panel 30 formed integrally around the panel 30 are coupled to the shelf frame 20. One region of the support frame 40 is inserted into the insertion portion 22 formed in the shelf frame 20 and seated on the support 23. In addition, the fixing part 24 fixes the support frame 40 coupled with the shelf frame 20.

Then, when the refrigerator 1 on which the shelf 10 is disposed is distributed to tropical and cold regions, the support frame 40 may be expanded or contracted due to the difference in the coefficient of thermal expansion of the panel 30 and the support frame 40. Change occurs. However, since the material having the same coefficient of thermal expansion responds to changes in length and temperature, the length, that is, the length of the support frame 40 from the panel 30 to the periphery is reduced, so that the change in expansion or contraction according to the temperature change becomes small. . In addition, there is a gap between the support frame 40 and the shelf frame 20 to correspond to the change in expansion or contraction of the support frame 40.

Thus, the structure is improved by a shelf having a support frame on which the panel is supported, and a shelf frame to which the support frame is coupled, and are coupled at intervals between the support frame and the shelf frame. It is possible to prevent cracking and lifting occurring between the frames.

In addition, since the support frame is made of a detachable type, it is easy to replace when a failure occurs in the panel or the support frame, and the replacement cost can be reduced.

As described above, according to the present invention, the structure is improved by a shelf having a support frame on which the panel is supported and a shelf frame to which the support frame is coupled, and coupled to the temperature change by a gap between the support frame and the shelf frame. There is provided a refrigerator capable of preventing a defect occurring between the panel and the support frame according to the present invention.

In addition, it is made of a separate type can be easily replaced when a failure occurs, thereby reducing the replacement cost.
