Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a refrigerator-freezer in which compartments are formed inside the refrigerator via partition plates, and in particular partitions facing through holes formed in the inner box before foaming. It is equipped with a partition plate into which an insertion piece integrally formed from a plate is inserted and fixed.

Prior Art A conventional example will be explained with reference to FIGS. 6 to 8. Reference numeral 1 denotes a refrigerator insulation box body, 2 an outer box, and 3 an inner box integrally molded inward to partition each chamber. 4 is a partition plate that divides the royal family into left and right. The partition plate 4 is U-shaped at the front of the box body 1, forming a partition wall 5 and extending back and forth, and the rear part is bent into an L shape so as to contact the inner surface of the inner box 3, and has several bent pieces 6. It has a long hole 7 and is fixed to the inner box 3 with a mounting screw 8. 9 is a heat insulating partition material inserted into the partition wall 5, and 1o is a front plate that covers the front surface of the partition wall 6. Reference numeral 11 denotes a foamed heat insulating material filled in the outer box 2 and the inner box 3. 12 is a shelf support integrally formed from the partition plate 4, and 13 is an internal shelf.

Problems to be Solved by the Invention However, the inner box is divided into upper and lower parts, and a partition plate made of synthetic resin or the like is inserted and fixed into contact with the inner surface of the lower inner box before foaming, thereby dividing the royal room into left and right parts. In the conventional structure, as described in the conventional technology, several elongated holes formed on the back partition plate that fixes the partition plate and the inner box simplify and rationalize the mold for manufacturing the partition plate. Unlike round holes, the holes are elongated, so several mounting positions on the back are A and B.
Installation variations occur due to misalignment in the direction, and when the C dimension is different from the entrance and the back, when installing the internal shelf to the shelf support formed integrally with the partition plate, the space between the shelf supports (left and right dimensions) is narrow and the shelf cannot fit. When sliding, there are cases where the shelf hits the shelf holder and vice versa (the shelf wobbles from side to side), which causes variations in the left and right width dimensions.

The present invention solves these conventional problems, and is a partition plate that comes into contact with the inner surface of the inner box to divide the lower chamber.As in the past, the rear mounting part is formed into an elongated hole in order to rationalize the mold for manufacturing the partition plate. However, in order to prevent the partition plate from shifting from side to side, an opposing insertion piece is formed integrally with the partition plate and inserted into the through hole separately provided on the back of the inner box, and its tip extends into the foam insulation material. Furthermore, due to the partition plate mounting structure, which is fixed with mounting screws through the long part,
To provide a partition plate that does not cause hit or rattling when installing or sliding a shelf in a refrigerator, and does not cause lateral positional deviation.

Means for Solving the Problems The present invention includes forming the front partition wall of the refrigerator body into a U-shape integrally with the partition plate that partitions the interior of the refrigerator-freezer, and the rear part thereof having an insertion piece facing the through hole of the inner box. At the same time as it is fitted and inserted, it comes into contact with the top, back, and bottom of the inner box in the layer, and is attached with screws through a portion of the inner box.

Function The present invention has the structure described above, in which several insert pieces integrally provided from the partition plate are fitted and inserted into the through holes provided in the grooves of the inner box, and further inserted into the top, back, and bottom of the inner box, respectively. Since the back of the partition plate comes into contact with the partition plate and is securely fixed to the inner box using several mounting screws, it is possible to secure the appropriate width for shelving inside the refrigerator without shifting the partition plate from side to side, making it easy to assemble. This provides a partition plate with good properties.

The separated partition plate 17 is inserted into the inner box 16 from the front of the inner box 16. A stepped portion 17c is inserted in the partition plate 17 so as to be in contact with the inner surface of the top surface, the back surface, and the bottom surface at right angles, and faces the groove portion 15c on the back surface provided in the inner box or the through hole 15d.
, the insertion pieces 17d are fitted or inserted into each other, and the tips of the insertion pieces 17d are projected between the inner box 16 and the outer box 14. At the same time, the flange piece 17b of the partition plate 17 is also inserted and mounted so as to contact the partition wall 161 protruding from the lower surface of the inner box 16 at right angles. Thereafter, the mounting piece 17e provided in the partition plate is fixed with the mounting screw 18 through the elongated hole, and the assembly into the inner box is completed. Thereafter, a heat insulating partition material 22 or a front abutment plate 23 is attached to the inside of the heat insulating partition wall 17a of the partition plate 17, and a pre-foaming box having a compartment 26 divided into left and right sections is completed. Furthermore, the refrigerator insulation box main body 13 is completed by attaching it to a suitable foaming jig and injecting a foam insulation material 24 such as diurethane through an injection port (not shown) on the back side of the outer box 14.

In the described partition plate configuration, the insertion pieces of the partition plate fit into several holes provided on the back of the inner box, so the mounting position of the partition plate to the left and right or front and back is reliably regulated, and no misalignment occurs. In addition, the top surface, back surface, and bottom surface of the partition plate are completely fixed to the inner box, and at the same time, the insertion piece extends into the urethane, so that the partition plate can be used as a holder for the internal shelf. In this case, a strong partition plate structure can be created.
