Abstract

PURPOSE:To prevent a heat insulation effect from being deteriorated even under high humidity condition by providing a water swell type sealer at an outlet of an electric wire laid in an accomodation casing, and molding the water swell type sealer into substantially the same shape of that of the outlet of the electric wire. CONSTITUTION:A refrigerator comprises an outer box 1 and an inner box 2, a heat insulating member 3 with which both boxes are filled therebetween, an accomodation casing 7 provided on the back of the outer box 1 for accomodating electric parts, etc., a cover 10 for covering the accomodation casing 7 therewith, and an electric wire 11 laid from the accomodation casing 7 to a storage chamber and buried in the heat insulating member 3. A water swell type sealer 13 is provided at an outlet of the electric wire in the accomodation casing 7, and is molded into substantially the same shape as that of the outlet of the electric wire and is mounted to bind the electric wire 11. Hereby, even if condensation is produced on the electric wire 11 cooled in a freezing chamber 4 under high humidity condition, the water swell type sealer 13 is swollen owing to condensed water to close any gap between the electric wires 11, so that water is prevented from entering the heat insulating member 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a storage case on the back for storing electrical components and the like.

[0002]

2. Description of the Related Art In recent years, refrigerators have been incorporated into Japanese Utility Model Publication No. 63-25512.
As disclosed in Japanese Patent Laid-Open Publication No. 2004-242242, a storage case for storing electrical components and the like is provided on the back surface in order to achieve serviceability.

An example of the conventional refrigerator described above will be described below with reference to the drawings. FIG. 3 shows a conventional refrigerator.

In FIG. 3, 1 is an outer box, 2 is an inner box, 3 is a heat insulating material filled between the outer box 1 and the inner box 2, 4 is a freezer in a storage chamber, and 5 is a partition wall 6. It is a refrigerating room in a partitioned storage room. Reference numeral 7 denotes a storage case arranged on the back surface of the outer case 1 for accommodating electrical components and the like (not shown), which is formed on the heat insulating material side of the outer case. Reference numeral 8 is a through hole provided in the inner box 2, and 9 is a through hole provided in the storage case 7. 10
Is a cover for covering the storage case. Reference numeral 11 is an electric wire embedded in the heat insulating material 3 guided to the storage case 7 from electric components (not shown) of the freezing compartment 4 and the refrigerating compartment 5. 12a and 12b are foam members wound around the electric wire 11 so as to be positioned in the through holes 8 and 9.

[0005]

However, in the above structure, the temperature of the electric wire 11 cooled in the freezer compartment 4 becomes low due to heat conduction, and the temperature of the electric wire outlet of the storage case 7 becomes low. Therefore, the dew condensation occurs on the electric wire 11 under the high humidity condition, and the dew condensation water passes through the gap between the electric wires 11 and the heat insulating material 3
However, there was a problem that the heat insulation effect was deteriorated by flooding.

In view of the above problems, the present invention provides a refrigerator in which the heat insulating effect does not decrease even under a humid condition.

[0007]

In order to solve the above-mentioned drawbacks, the refrigerator according to the present invention is provided with a water expansion sealer at the outlet of the electric wire in the storage case, and the water expansion sealer is stored in the storage case. It has a configuration in which it is molded into a shape that is substantially the same as the shape of the wire outlet portion inside the space.

[0008]

According to the present invention, the electric wire having a low temperature at the electric wire outlet portion of the storage case is provided with a water expansion type sealer at the electric wire outlet portion of the storage case and has a water expansion type seal. -If the dew condensation occurs on the electric wire by molding the wire into a shape that is substantially the same as the shape of the wire outlet in the housing case, the water expansion type sealer expands due to the dew condensation water, and Since the wire outlet is closed, no water will enter the insulation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A refrigerator according to an embodiment of the present invention will be described below with reference to the drawings. It should be noted that the same components as those of the related art are designated by the same reference numerals and detailed description thereof will be omitted.

FIGS. 1 and 2 show a refrigerator according to an embodiment of the present invention. In FIGS. 1 and 2, reference numeral 13 denotes a storage case.
It is a water expansion type sealer provided at the electric wire outlet of the space 7,
The electric wire 11 is formed into a shape substantially the same as the shape of the electric wire outlet.
It is attached so as to bind.

In the above structure, even if dew condensation occurs on the electric wire 11 cooled by the freezer compartment 4 under a high humidity condition, the dew condensation water expands the water-expandable sealer 13 to close the gap between the electric wires 11. , To prevent water from entering the heat insulating material 3.

[0012]

As described above, according to the present invention, an outer box, an inner box, a heat insulating material filled between the two boxes, and a storage case for storing electrical components and the like on the back surface of the outer box. The storage case includes a cover for covering the storage case and an electric wire embedded in the heat insulating material wired from the storage case to the storage chamber.
A water expansion sealer is provided at the wire outlet in the casing, and the water expansion sealer is molded into a shape that is substantially the same as the shape of the wire outlet in the storage case. It is possible to prevent water from entering the heat insulating material.
