DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 2 is a side vertical sectional view of the refrigerator.
And a freezer compartment is provided at the lowermost portion of the main body in two stages of an upper freezer compartment 3 and a lower freezer compartment 4, and doors 5, 6, 7, 8 are provided at the front openings of the respective compartments. I have.

The vegetable compartment 2 and the upper freezer compartment 3 are partitioned by an insulated partition wall 10, the details of which are shown in FIG. The inner partition wall 10 is formed integrally with the inner box 9 forming the bottom surface 2a of the vegetable compartment 2 and the ceiling surface 3a of the upper freezer compartment 3, and has a partition member 11 over its entire width on the front opening side. Provided.

The partition member 11 includes a partition plate 12 that forms a front opening surface of the main body, and a dew-proof pipe 13 that forms a part of a refrigeration cycle that is closely mounted on the back surface of the partition plate 12 in the width direction.
And a partition cover 14 that covers these from the rear. The rear end of the partition cover 14 extends rearward and is fitted to the front end of the intermediate partition wall 10.

A magnet portion 15a of a gasket 15 attached to the periphery of doors 6 and 7 for opening and closing the front openings of the vegetable compartment 2 and the freezing compartments 3 and 4 is in close contact with the front surface of the partition plate 12, and heat leaks from the openings. Is shut off.

A plurality of raised ribs 16 are formed to extend forward and downward from the rear surface of the partition cover 14 over the entire width of the storage room. Pressed and fixed. Reference numeral 17 denotes partition ribs which are similarly formed by extending forward from between the convex ribs 16, and partition the partition space formed by the partition plate 12 and the partition cover 14 together with the convex ribs 16 into upper and lower small partitions 18. ing.

The partition member 11 is fixed by fixing the partition cover 14 to the front surface of the middle partition wall 10 and then filling the heat insulating space of the refrigerator body with a heat insulating material made of polyurethane. Part 19 of the partition wall 10
The partition cover 14 at the front opening of the middle partition wall 10.
By firmly adhering to the back wall surface, it is firmly fixed by its adhesive force.

As a method of assembling the partition member 11, as shown in FIG. 3, the partition cover 14 may be fitted and fixed to the intermediate partition wall 10 previously filled with the foam insulation 19.

Since the vertical intervals between the ribs 16 and the small sections 18 formed by the section ribs 17 are several millimeters, natural convection of the air in the small section 18 space is not performed, and a good heat insulating effect is obtained. The heat transfer between the upper and lower storage rooms and the outside of the refrigerator can be blocked to prevent heat leakage.

As a result, the storage chambers 1, 2, 3, and 4 can be maintained at appropriate temperatures without performing useless cooling operation, so that power consumption can be reduced.

FIG. 4 is a sectional view of a partition member according to a second embodiment of the present invention, and a plurality of ridges extending forward from the back wall of the partition cover 14 over the entire width of the storage room. Rib 1
6 connecting the upper and lower front ends in the central portion
The flat portion 20 is formed so as to be in close contact with the back surface.

Accordingly, the dew-proof pipe 13 serving as a heating element
Is diffused throughout the partition plate 12 by contact conduction not only with the local portion of the partition plate 12 due to line contact but also with the close contact flat portion 20 of the partition cover 14, which is uniformly heated and exposed to the front surface of the partition plate 12. The effect of preventing sticking can be improved.

FIG. 5 is a perspective view of a partition plate portion according to a third embodiment of the present invention, in which a large number of vertical ribs 21 are formed to extend from the back wall of the partition cover 14, and the inside of the partition space is formed. The small section 18 is formed by being divided in the width direction.

The convex ribs 21 may be formed so as to extend in both the vertical and horizontal directions in combination with the widthwise convex ribs 16 of the second embodiment. In short, a small section in which air convection hardly occurs is formed. Just fine.

Further, as shown in FIG.
If the seal member 21 is provided at the engagement portion between the partition 2 and the partition cover 14, the partition space formed by the partition plate 12 and the partition cover 14 and the outside are completely shut off from the air, and the heat insulating effect is further improved.

In each of the above embodiments, the vegetable room 2
Although the partition member 11 installed between the first freezer compartment 3 and the upper freezer compartment 3 has been described, the partition member is not limited thereto, and may be a heat insulating partition wall that separates the refrigerator compartment 1 from other compartments.

[0028]

As described above, according to the middle partition structure of the refrigerator of the present invention, natural convection in the middle partition space is prevented by the small section formed by the ridged rib, so that the conventional styrofoam or the like can be used. Insulation performance is better than that of the conventional heat insulation structure, and the amount of power consumption can be reduced by suppressing the amount of heat leaking into the refrigerator. Since man-hours can be simplified, costs can be reduced.

According to the second aspect of the present invention, a small section is formed by the convex rib extending from the partition cover in the direction of the partition plate, and the dew-prevention heating body is pressed and fixed to the partition plate side. Further, it is possible to improve the heat exchange efficiency with the partition plate and achieve a good dew-prevention effect without requiring any other fixing device for the dew-prevention heating body.

According to the third aspect of the present invention, the contact surface between the dew-prevention heating element and the partition plate is reduced by integrally forming a flat surface in contact with the partition plate on the front surface of the extended convex rib. By increasing the uniform diffusion of heat conduction, the dew-prevention effect can be further improved.

According to the fourth aspect of the present invention, a good air insulation effect can be obtained by the small section in which air convection hardly occurs. According to the fifth to seventh aspects, the partition cover by injection molding. There is no need to employ a complicated molding method.

According to the eighth aspect of the present invention, the joint between the partition plate and the partition cover is hermetically sealed, so that the space inside the partition member and the outside of the partition plate and the partition cover are completely shut off from the air. A better heat insulating effect can be obtained.
