[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With the above-described configuration, a refrigerator having good heat insulating properties of a partition portion and hardly causing dew condensation in the partition portion can be obtained.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an embodiment of the present invention shown in FIGS. 1 to 3 will be described. Urethane foam is injected and foamed between an inner box 1 formed of a resin such as ABS constituting an inner wall surface of the cabinet and an outer box 2 made of a sheet metal such as a thin steel plate constituting an outer casing of the main body.
A refrigerator compartment 11 is provided in the upper part of the refrigerator, a vegetable compartment 12 is provided in the center, and a freezing compartment 13 is provided in the lower portion. An evaporator compartment 14 having an evaporator 15 therein is provided on the back of the vegetable compartment 12 and the freezing compartment 13. .
In the front between the vegetable compartment 12 and the freezer compartment 13, a partition 4 internally provided with a hot pipe 3 for preventing dew condensation on the front face against which the door 17 abuts is fixedly provided on the left and right inner surfaces of the inner box 1. . An L-shaped partition wall 16 as viewed from the side that partitions the vegetable compartment 12 and the freezing compartment 13 and the vegetable compartment 12 and the evaporator compartment 14 that is molded from a resin such as ABS and contains a styrene foam insulation material therein, The inner box 1 at the upper rear of the vegetable compartment 12
Then, the step provided at the front end of the partition wall 16 is fitted to the step provided at the rear of the partition 4 so as to be placed thereon, and is fixed by a push rivet or the like (not shown).

The partition 4 is constructed as follows. A concave portion formed on the left and right wall surfaces of the inner box 1 by opening the front surface, forming holes 5a on the left and right side surfaces, providing convex portions 5b on the inner upper, lower, left and right wall surfaces, and forming a partition body 5 formed of a resin such as ABS. To fit. In the recess of the inner box, a hole 1a communicating with the hole 5a on the left and right side surface of the partition body 5 is formed, and around the hole 1a, a sealing material 10 made of urethane sponge or the like is stuck. A heat insulating material 6 made of Styrofoam is stored in the partition body 5 in contact with the convex portion 5b, and one sealing material 7 made of urethane sponge or the like is placed inside the heat insulating material 6 and the inside of the partition body 5. The hot pipe 3 is accommodated in contact with the front surface of the sealing material 7, and bent portions 8 a to be inserted into concave portions 5 c provided on upper and lower opening end surfaces of the partition body 5 are provided vertically. Partition plate 8 made of sheet metal such as thin steel plate
The hooks 8b provided on the left and right sides of the partition plate 8 are hooked on the openings 2a formed in the outer box 2, the bent portions 8a are fitted into the concave portions 5c, and are attached to the hot pipes 3 by contact. When the urethane resin 9 is foamed and injected between the inner box 1 and the outer box 2 in the assembled state as described above, the holes 1a and 5a formed so as to communicate with the inner box 1 and the partition body 5 are formed. Then, the urethane resin 9 is foamed and injected into the partition 4.

The foamed and injected urethane resin 9 pushes the heat insulating material 6 from behind, presses the hot pipe 3 against the partition plate 8, and reliably transfers heat from the hot pipe 3 to the partition plate 8. By doing so, the prevention of dew condensation on the partition plate 8 can be improved. Further, since the urethane foam resin has better heat insulating properties than the styrene foam, the heat of the hot pipe 3 is transmitted to the inside of the refrigerator, and the rise in the temperature of the refrigerator can be reduced.

The sealing member 7 is provided between the heat insulating material 6 and the hot pipe 3 to prevent the urethane resin 9 from leaking to the hot pipe 3 side. The urethane resin 9 can be prevented from leaking to the outside from the gap between the urethane resin 9 and the resin.

[0013] Between the contact surface between the partition 4 and the inner box 1,
By tightly fitting the sealing material 10 so as to surround the holes 1a, 5a, it is possible to prevent the urethane resin 9 from leaking out of the gap to the outside even if the dimensions of the inner box slightly vary.

Next, another embodiment of the present invention shown in FIG. 4 will be described. The configuration of the partition is different from that of the above embodiment. Forming the partition body 5 integrally with the partition wall 16;
A plurality of holes 16a are formed on the side surface of the partition wall 16, and holes 1a communicating with the holes 16a are formed on both left and right wall surfaces of the inner box 1. The urethane resin 9 is injected and foamed from the plurality of holes 1a and 16a to the entire inside of the partition wall 16.

Since the urethane foam resin has better heat insulating properties than the styrofoam, the heat insulating property between the vegetable compartment 12 and the freezing compartment 13 is improved, so that the vegetable compartment 12 is improved.
And the freezing room 13 can be stabilized in cooling temperature.

[0016]

As described above, according to the present invention,
The refrigerator has a good heat insulation property of the partition part and hardly causes dew condensation in the partition part.
