DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a refrigerator having a refrigerator or a freezer having two or more different temperature zones.
The present invention relates to a technique for preventing dew condensation on a partition wall between rooms and reducing power consumption.

[0002]

2. Description of the Related Art In recent years, in refrigerators and refrigerators, rooms have been subdivided due to a large capacity and a difference in temperature zone, and prevention of dew condensation on a partition wall of each room and further reduction in power consumption have been demanded. .

[0003] As a conventional refrigerator-freezer, Japanese Utility Model No. 5-10
975 is disclosed.

Hereinafter, the above-mentioned conventional refrigerator-freezer will be described with reference to the drawings. FIG. 10 is a longitudinal sectional view of a main part of a partition wall of a conventional refrigerator-freezer. In FIG. 10, 1 is a freezing room,
2 is a refrigerator room. On the front surface of the partition wall 3, a resin plate 5 having a U-shaped cross section by burying an iron plate 4 is attached. The iron plate 4 is bent at its end into a U-shape to form a folded portion 4.
a is formed, and the front surface and the surface of the folded portion 4a are exposed to the front and back surfaces of the resin plate 5, and the folded portion 4a is in contact with the condensation pipe 6. When the doors 7 and 8 are closed, the packing magnets 11 and 12 of the door packings 9 and 10 are attracted to the surface of the iron plate 4 to maintain the closed state.

The operation of the partition wall 3 of the refrigerator having the above-described structure will be described below.

When the opening and closing doors 7 and 8 are closed, the heat of the condensing pipe 6 is transmitted to the door packings 9 and 10 via the iron plate 4 and the packing magnets 11 and 12 to warm them, and as a result, the door packings 9 and 10 are heated. To prevent the occurrence of condensation. On the other hand, the heat of the iron plate 4 warmed by the condensing pipe 6 acts to warm the resin plate 5 to which the iron plate 4 is fixed, but the heat conductivity of the resin is generally about 1/25 that of iron.
The heat of the iron plate 4 is hardly transmitted to the resin plate 5. As a result, although a part of the resin plate 5 is in contact with the cold air in the freezer compartment 1 and the refrigerator compartment 2, the temperature of the resin plate 5 hardly rises as described above. Is prevented from being driven.

[0007]

However, since the heat of the condensation pipe 6 is used as a heat source for preventing dew condensation in the above-mentioned conventional configuration, the heat is always transferred even when the temperature and humidity of the outside air do not dew. This has the disadvantage that extra heat leaks into the refrigerator cabinet.

An object of the present invention is to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a refrigerating refrigerator that minimizes heat leakage into a refrigerator storage while preventing dew condensation.

Another subsidiary object of the present invention is to hold and fix the resin plate on the front surface of the partition wall without using a fixing additional material such as a screw.

Another subsidiary object of the present invention is to minimize the step on the front of the partition wall when the door packing is attracted to the front of the partition wall.

Another subsidiary object of the present invention is to make the door packing stick to the front surface of the resin partition wall.

Another subordinate object of the present invention is to fix an iron plate for adsorbing door packing without using a fixing additional material such as a double-sided tape.

Another subsidiary object of the present invention is to improve the workability of inserting a resin plate when assembling a partition wall.

Another subordinate object of the present invention is to securely fix a partition rib that separates a section where a dew condensation prevention heater is laid from a heat insulator.

Another subsidiary object of the present invention is to fix the upper plate and the lower plate constituting the partition wall without using a fixing additional material such as a screw.

A further primary object of the present invention is to more reliably prevent condensation. Another dependent object of the present invention is to prevent dew condensation with a low power consumption dew condensation prevention heater.

[0017]

In order to achieve these objects, the present invention is to provide a heater for preventing dew condensation on the inner surface of a resin plate in front of a partition wall, thereby reducing the outside air temperature and the temperature.
By controlling the heater based on the outside air humidity, it is possible to prevent excess heat leak into the refrigerator compartment.

Further, since the resin plate is sandwiched between the front flanges of the upper plate and the lower plate, the resin plate can be held and fixed without using a fixing additional material.

Further, by using a resin plate whose upper and lower ends have an L-shaped cross section as a plate on the front surface of the partition wall, when the door packing is attracted to the front surface of the partition wall, the step on the front surface of the partition wall is minimized. can do.

A groove formed by a pair of guide ribs between the front flange of the upper plate and the partition rib, and a groove formed by a pair of guide ribs between the front flange of the lower plate and the rib for holding the partition rib, By adopting a configuration in which the upper flange and the lower flange of the resin plate are inserted, the workability of inserting the resin plate can be improved.

Further, by forming retaining claws on both left and right ends of the resin plate integrally with the resin plate and engaging with the inner surface of the front flange of the outer box, the resin plate can be fixed without using an additional material for fixing. Can be held and fixed.

By laying iron plates on the upper and lower ends of the resin plate, the door packing can be adsorbed on the front surface of the resin partition wall.

[0023] Further, by forming a round hole and inserting an iron plate provided with a cutout penetrating from the end surface into the round hole into an iron plate holding boss formed integrally with the resin plate, the fixing additional material can be provided. The iron plate for adsorbing the door packing can be fixed without using it.

In addition, the partition ribs from the upper plate are inserted into the grooves formed by the ribs for retaining the ribs on the lower plate, so that the section where the dew condensation prevention heater is laid and the section of the heat insulator can be reliably formed. You can partition.

Further, by forming a locking hole on the side of the partition rib and fitting a locking claw from the lower plate into the locking hole, the partition wall can be formed without using an additional material for fixing. Upper and lower plates can be fixed.

Further, by forming a protruding portion over the entire width at the center of the resin plate, the surface area of the resin plate can be increased,
Dew condensation can be more reliably prevented.

By laying a dew condensation prevention heater on the inner surface of the projecting portion of the resin plate, dew condensation can be prevented by the dew condensation prevention heater consuming less power.
