Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator in which a recess for accommodating electrical components is formed on the back side of a refrigeration box, and a capacitor is thermally attached to the back plate of the refrigeration box.

Conventionally, a capacitor has been attached to the inner surface of the back plate of a refrigeration box for thermal conductivity to prevent the capacitor from being exposed outside the refrigeration box, thereby improving the appearance of the refrigeration box, especially on the back side. A refrigerator is provided.

In such a refrigerator, a recess is formed on the back side of the refrigerator box, and electrical components such as connectors for internal wiring are housed in the recess.

However, if the distance between the recess and the cold source (freezing room or refrigerator compartment) inside the refrigerator box is set small, the influence of the cold heat from the cold heat source is likely to reach the inside of the recess, resulting in condensation inside the recess. This causes problems such as lowering the insulation resistance of electrical components such as connectors and corrosion of the back plate.In addition, if the distance between the recess and the cold source is set large to deal with this problem, Since the thickness of the heat insulating wall portion must be increased, not only does the overall external size become larger, but also a large amount of heat insulating material is required, leading to problems such as high costs.

For this reason, in the past, the recess was formed with a shallow bottom to ensure a distance between the recess and the cold source, and the cover that was attached to the recess was formed in the shape of a container protruding from the refrigerated box body, so that the depth of the recess was substantially reduced. The structure is designed to secure a large internal volume, and each of the above-mentioned problems is solved.

However, in such a conventional configuration, the cover protrudes from the refrigerator box, so that the appearance of the refrigerator box deteriorates even though the appearance of the refrigerator box, especially on the rear side, has been improved as described above. Ta.

The present invention was developed in view of the above circumstances, and its purpose is to form a recess for storing electrical components on the back side of the refrigerator box, and to place a capacitor on the back plate of the refrigerator box for heat transfer. To obtain effects such as being able to prevent dew condensation from forming in a recessed part without deteriorating the appearance of the refrigerator box, especially on the rear side, in a refrigerator installed in the refrigerator.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a refrigerating box body of, for example, a two-temperature refrigerator, which has an outer box 3 whose back opening is closed with a back plate 2, a cooler 5 with a 4-type freezer compartment, and an inner box (not shown). The structure is such that the heat insulating wall portion 6 is formed by filling a heat insulating material such as polyurethane foam.

Further, 7 is a condenser that is heat-transferably attached to the inner surface of the back plate 2, and forms a cooling cycle together with the compressor 8, the cooler 5, etc.

9 is a heat insulating wall portion 6 at the upper left corner of the refrigerator box body 1.
A recess formed by burying the partition container 10 in the
An opening 2a is formed in a portion of the back plate 2 facing the opening 9a.

Reference numeral 11 denotes a heat transfer sheet made of aluminum foil, for example, which is attached from the inner bottom surface to the inner surface of the recess 9, and one end thereof is thermally bonded to the back plate 2.

A connector 13, which is an electrical component of the internal wiring 12, is housed in the recess 9, and a flat cover 14 is attached to the recess 9 so as to close the opening 9a.

According to the present embodiment described above, the heat transfer sheet 11 is
The heat transfer sheet 1 is attached from the inner bottom surface to the inner surface of the heat transfer sheet 1, and one end of the heat transfer sheet 1 is attached to the back plate 2 on which the capacitor 7 is heat transferably attached.
1 transfers the heat of the capacitor 7 to the recess 9 through the back plate 2.
can be transmitted internally.

Therefore, there is no risk of condensation forming in the recess 9 due to the influence of cold heat from the cooler 5, and it is possible to effectively prevent the insulation resistance of the connector 13 portion from decreasing or the back plate 2 from corroding. .

Since the influence of cold heat from the cooler 5 can be excluded in this way, the distance between the recess 9 and the cooler 5 (shown in the middle of FIG. 2) is set small, and the insulating wall 6 between them is set small. There is no problem even if the thickness of the recess 9 is made small, and therefore, the recess 9 can be made deep to ensure its internal volume.

In this way, the cover 14 can be made into a flat plate shape so that it does not protrude from the refrigerator box 1 as in the conventional case, so there is no risk of degrading the appearance of the refrigerator box 1, especially on the back side.

Furthermore, as described above, since the thickness of the heat insulating wall body 6 can be made small, there is no risk of the overall size becoming large or that a large amount of heat insulating material is required, resulting in high costs.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings; for example, the electrical component accommodated in the recess may be a solenoid valve, etc., and can be implemented with various modifications without departing from the gist thereof.

According to the present invention, as is clear from the above description, a refrigerator is provided with a recess for storing electrical components, etc., formed on the back side of the refrigeration box, and a capacitor is thermally attached to the back plate of the refrigeration box. In this case, it is possible to achieve effects such as being able to prevent dew condensation from forming within the recessed portion without degrading the appearance of the refrigerator box, particularly on the back side.
