Description

[Detailed description of the invention] Industrial applications The present invention relates to a refrigerator.

BACKGROUND OF THE INVENTION In recent years, as a means of preventing dew condensation on the front flange of an outer box of a refrigerator, a part of a condenser constituting a cooling device has often been disposed in a groove formed in the front flange.

An example of a structure in which a condenser pipe is disposed in a groove on the front surface of a conventional refrigerator will be described below with reference to the drawings in FIGS. 3 and 4. Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3 made of synthetic resin, and a foamed heat insulating material 4 filled between the boxes 2 and 3. Reference numeral 6 denotes a substantially U-shaped groove provided in the front flange portion 6 of the outer box 2, into which the condenser piping 7 and the front flange 8 of the inner box 3 are inserted. 9 is a sealing heat insulating material for preventing leakage of the foam heat insulating material 4.

1o is the U-shaped bottom part 11 of the groove 5 and the side part 1 of the outer box 2.
It is a thermally conductive filler to improve the heat conduction of the foam insulation material 2, and is filled before the foam insulation material 4 is injected, so that the foam insulation material 4 is
It flows into the bottom surface 11 of the groove 5 and the side surface 12 of the outer box 2, preventing deterioration of heat conduction and promoting heat radiation from the condenser pipe 7.

Problems to be Solved by the Invention However, in the above configuration, since the cross-sectional shape of the condenser pipe 7 is cylindrical, there is relatively good contact with the bottom surface 11 of the groove 6; 5, and the sealing heat insulating material 9 is in contact with the surface of the condenser piping 7 on the front flange 8 side of the inner box 2. Since the heat cannot be conducted to the front flange portion 6 and side surface portion 12 of the box 2, there is a problem in that a sufficient heat dissipation effect cannot be obtained.

In view of the above problems, the present invention makes it possible to easily and inexpensively improve the thermal conductivity of the side surface of the concave groove 5 of the condenser pipe 7 and the sealing heat insulating material 9 side.

Means for Solving the Problems In order to solve the above problems, the technical means of the present invention is to provide a soft thermally conductive member on the end face of the sealing heat insulating material on the condenser pipe side, and to cover the entire circumference with a thin member. It has a structure that covers it.

Effect: With the above-described configuration, the present invention allows heat from the condenser piping to be conducted through the conductive member and efficiently transmitted to the front flange portion of the outer box and the side portions of the groove, thereby reducing heat dissipation from the condenser piping. The effect can be increased.

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

Components that are the same as those in the conventional example are given the same numerals and their explanations will be omitted. In Fig. 1, 13 is a heat insulating material for sealing.
14 is a soft thermally conductive member made of steel wool. 16 is a thin member made of a very thin film;
By covering the entire circumference with the thin-walled member 14, the sealing insulation material 1
2 and the thermally conductive member 13 are integrally formed. 1o is a thermally conductive filler, which is filled between the side surface 16 of the groove 5 and the side surface 12 of the outer box 2, which the thermally conductive member 14 is in contact with.

Next, the method for forming the above structure will be described in detail. First, the condenser pipe 7 is inserted into the groove 5. Next, the sealing heat insulating material 13 integrated with the thermally conductive member 14 is inserted, and the condenser piping 7
into the bottom surface 11 of the groove 6. Next, a thermally conductive filler 1o is filled between the side surface of the groove 6 and the side surface 12 of the outer box 2. After that, the front flange 8 of the inner box 3 is inserted between the sealing heat insulating material 13 and the front flange 6 of the outer box 2, and the space formed by the outer box 2 and the inner box 3 is filled with the foam heat insulating material 4, and the refrigerator is heated. A main body 1 is formed.

As described above, according to this embodiment, the condenser pipe 7 inserted into the bottom 11 part of the groove 5 and the entire circumference inserted into the groove 6 are covered with a thin member 16 made of a thin film. A sealing heat insulating material 13 integrally formed with a thermally conductive member 14 and a thermally conductive filler 1o between the side surface portion 16 of the groove 6 and the side surface portion 12 of the outer box 2 are provided. Heat is transferred from the thermally conductive member 14 to the side surface portion 16 of the groove 6 to the thermally conductive filler 1
0→Since heat is effectively radiated from the side surface 12 of the outer box 2, heat radiation from the condenser piping 7 can be greatly promoted. In addition, since the entire circumference of the sealing heat insulating material 12 is covered with the thin member 16 made of a thin film, the sealing heat insulating material 13
To prevent the surface of an outer box 2 from being damaged when inserting it into a groove. Furthermore, since it is possible to prevent moisture from entering the thermally conductive member 14, there is no quality problem even if inexpensive steel wool is used for the thermally conductive member 14.

Effects of the Invention As described above, the present invention provides a groove formed in the front flange portion of the outer box, a front flange of the inner box inserted into the groove,
A sealing insulating material that is integrally formed with a soft thermally conductive material that is pressed against the side surface of the groove and the flange surface of the inner box to prevent leakage of the insulation material, and a part of the condenser that is inserted into the bottom of the groove. The condenser piping has a circular cross section, and a thermally conductive filler is filled between the side surface of the groove and the side surface of the outer box. Since heat can be effectively radiated from the outside to the side surface of the outer box, heat radiation from the condenser piping can be greatly improved.
