Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator in which two chambers are partitioned and formed on the left and right in a refrigerator via a partition plate.

Conventional Technology A conventional example will be described with reference to FIGS. 7 to 9. Reference numeral 1 is a refrigerator heat insulating box body, 2 is an outer box, and 3 is an inner box having partition walls 3a and 3b integrally formed and extended inward so as to partition each chamber. 4 and 5 are bottle compartments, refrigerating compartments, and 6 compartments divided into left and right by the partition wall 3b.
Is a convection through hole to the bottle chamber 4 and the refrigerating chamber 5 provided in the partition wall 3b. Reference numeral 7 is a connecting cylinder for sealing the through hole 6, and a seal member 8 is attached to the entire circumference flange portion 7a.
Reference numeral 9 denotes a separate partition decorative frame formed in a U-shape that covers the front surface of the partition wall 3b and opens toward the front surface, and is fixed with 10 screws. 11 is a heat insulating partition member to be inserted inside the partition decorative frame 9, 12
Is a cross rail that covers the front surface of the partition decorative frame 9. Reference numeral 13 is a foam heat insulating material filled between the outer box and the inner box or the partition wall.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, a partition wall for partitioning a bottle chamber (bottle, can storage chamber) and a refrigerating chamber, which have a small temperature difference between the left and right chambers, is integrally formed by using a part of an inner box. When a cold air convection hole (between the bottle chamber and the refrigerating chamber) is provided to fill the inside with the foam insulation material, a separate connecting tube and seal member are required, and the workability of installation is poor and the foam insulation material is further applied to the partition wall. Due to the filling, the ineffective volume increases and the internal volume decreases. Further, since the partition decorative frame for attaching the cross rail to the front part of the heat insulating partition wall is separately fixed to the partition wall via the screw, there is a problem that the cost and the number of mounting steps are increased.

SUMMARY OF THE INVENTION It is an object of the present invention to solve such conventional problems and to provide a refrigerator with improved assemblability and fewer parts.

Means for Solving the Problem The refrigerator of the present invention is an inner box that is formed of a synthetic resin and constitutes a refrigerating compartment, and a strip-shaped convex portion that protrudes inward of the refrigerating compartment over the top, back, and bottom of this inner box, Grooves formed in this convex portion, a partition plate formed of a synthetic resin that abuts the convex portion and the groove and divides the refrigerating chamber into left and right chambers, a through hole formed in this partition plate, and the partition plate A vertical wall that is integrally formed at the front end and covers the front surface of the convex portion, opens the front surface side and is screwed to the inner box, the heat insulating material housed in this wall, and the metal cover that covers the front surface of the heat insulating material. It is composed of cross rails.

Effect According to the present invention, since the wall is integrally formed from the partition plate with the above-described configuration, it is not necessary to attach a separate component, the assemblability is good, and the partition plate made of synthetic resin can be thinly formed. The food storage space in the two rooms can be increased (internal volume increased).

Embodiment An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 14 is a refrigerator heat insulating box main body, 15 is an outer box, and 16 is a partition wall 16a integrally formed and extending inwardly so as to partition the upper and lower chambers, and the lower chamber divided into two parts is projected inwardly over the top, back and bottom surfaces of the lower chamber. A strip-shaped convex portion 16b, and a groove 16 partially provided on the ceiling convex portion 16b.
It is an inner box provided with c and protrusions 16d on the left and right of the rear convex portion 16b. Reference numeral 17 is a synthetic resin partition plate made of ABS resin that partitions the lower chamber to the left and right. The partition plate 17 has a substantially U-shaped cross section in the front part of the box body 14, and integrally forms a wall 17a having a front side opening, and extends in the front-rear direction. The wall 17a covers the front surface of the convex portion 16b. Further, the partition plate has an upper edge 17b fitted to the groove 16c on the upper part, a flange piece 17c fitted to the protrusion 16d, a through hole 17d for convection of the cool air of the left and right chambers, and a mounting hole 17e integrally. It is formed on the partition plate 17. Reference numerals 18 and 19 denote a bottle compartment and a refrigerating compartment, which are divided by the partition plate 17 and store bottles, cans and the like having a small temperature difference. 20 is a screw for fixing the partition plate, 21 is a heat insulating material to be inserted from the partition plate 17 into the wall 17a integrally formed in a U shape, 22 is a metal cloth covering the front surfaces of the wall 17a and the heat insulating material 21. It is a rail. 23 is the outer box
A foamed heat insulating material filled between 15 and the inner box 16 or the partition wall 16a. Here, the assembly method of the present invention will be described with reference to FIG. In front of the refrigerator heat-insulating box main body 14, a belt-shaped convex portion 16 is provided in advance on the inner box 16 with a partition plate 17 for dividing the lower chamber of the inner box 16 into left and right.
b Insert so that the top surface, back surface, bottom surface, groove 16c, and back projection 16d are in contact with each other toward the surface, and then insert the partition plate 17 with the screw 20 through the mounting hole 17e provided in the front heat insulation partition wall. It is fixed to the inner box 16 and the inner box assembly is completed. Then put the inner box assembly into the outer box body 15
After inserting into the wall 17a of the partition plate 17, the heat insulating material 21 or the cross rail 22 is mounted, and further mounted on a suitable foaming jig, and the urethane is injected from the injection port (not shown) on the back surface of the outer box 15. Since the refrigerator insulation box body 14 is completed by injecting the foam insulation material 23, etc., the assembly work is simple and the top, back and bottom surfaces of the partition plate are completely adhered and fixed to the inner box. It has a partition structure.

EFFECTS OF THE INVENTION According to the present invention, since the front wall of the box body is integrally formed from the partition plate made of synthetic resin that divides the two chambers having a small temperature difference as described above, there is no need for a separate partition frame, etc. Improvement and cost reduction can be achieved. Further, since the partition plate is made of synthetic resin, a convection hole can be easily provided, and a separate communication cylinder member is not required, and the cost can be reduced. Also, because the partition wall structure does not require a heat insulating layer on the partition walls of the two chambers, the previous ineffective portion has an effective internal volume, and the internal volume can be increased, and it is also possible to easily form a shelf structure integrally with the partition plate. The required strength structure is such that the partition plate can be easily fixed with a foamed heat insulating material, and the integrated partition plate specification can bring about great effects such as improving the internal appearance.
