Hereinafter, a process of mounting a box casing in a preferred embodiment of a refrigerator box casing fixing structure and a refrigerator including the same according to the present invention will be described with reference to the accompanying drawings.

3A to 3C are operation state diagrams illustrating a process of mounting the box casing to the storage box cover in a preferred embodiment of the refrigerator box casing fixing structure and the refrigerator including the same according to the present invention.

First, as illustrated in FIG. 3A, the box casing 80 is pushed into the storage space 61 while the storage box cover 70 is mounted in the storage space 61. At this time, the support ribs 83 of the box casing 80 are formed by the casing support rails 65 of the storage space 61 and the auxiliary rails 76A of the storage box cover 70 and the storage box cover 70. It starts to slide along the casing support rail 74A.

As shown in FIG. 3B, when the box casing 80 is continuously pushed into the storage space 61, the support ribs 83 are casing support rails 65 of the storage space 61 and The fixed ribs 78 begin to be inserted into the fixing grooves 84 by sliding along the auxiliary rails 76A of the storage box cover 70 and the casing support rails 74A of the storage box cover 70. As described above, in the process of inserting the fixing rib 78 into the fixing groove 84, the contact protrusion 85 is inserted into the fixing groove 78 by the fixing rib 78 in the direction in which the fixing rib 78 is inserted into the fixing groove 84. It is elastically deformed in the direction perpendicular to it. In addition, the fixing rib 78 is guided to the fixing groove 84 by the inclined guide surface 85A of the contact protrusion 85.

Meanwhile, as shown in FIG. 3C, when the box casing 80 is completely mounted in the storage space 61, the fixing rib 78 is completely inserted into the fixing groove 84. Therefore, the box casing 80 does not flow from side to side in the state of being mounted in the storage space 61.

In addition, when the fixing rib 78 is completely inserted into the fixing groove 84, the contact protrusion 85 is in close contact with one side of the fixing rib 78. Therefore, the fixing rib 78 is not removed arbitrarily in the state of being inserted into the fixing groove 84. In other words, the fixed rib 78 is not fixed to the fixing groove 84 by pulling the box casing 80 to the outside of the storage space 61 with a predetermined size, that is, a force greater than or equal to the elastic force of the contact protrusion 85. Is removed). Therefore, the box casing 80 is not arbitrarily removed in the mounted state of the storage space 61 in the process of dispensing the storage box 90 into and out of the mounting space 80S of the box casing 80.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. .

According to the refrigerator box casing fixing structure and the refrigerator including the same according to the present invention configured as described above, when the box casing is mounted in the storage space, the fixing ribs provided in the storage box cover in the fixing groove provided in the box casing Is inserted. Therefore, since the box casing is prevented from flowing left and right in the state of being mounted in the storage space, it is possible to expect the effect of improving the usability of the product.
