Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for radiating heat from a part of a condenser by disposing a part of a condenser in a groove part formed in a front 7 flange part of an outer box forming a heat insulating box. This invention relates to a refrigerator that prevents dew condensation through its action.

BACKGROUND OF THE INVENTION In recent years, as a means to prevent condensation on the front flange of the outer box of a refrigerator, condenser piping, which forms part of the condenser constituting the cooling device, has been installed in a groove formed in the front flange of the outer box. It is set up. Furthermore, in order to improve the heat dissipation efficiency of the condenser piping, a thermally conductive member is often inserted into the groove.

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 to 6. Reference numeral 1 denotes a refrigerator body, which includes 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 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. A sealing heat insulating material 9 is inserted into the groove 6 under pressure to prevent the foamed heat insulating material 4 from leaking. The sealing heat insulating material 9 is formed by integrally forming a compressible heat insulating material 1o and a thermally conductive member 11 such as steel wool,
The entire circumference is covered with a thin member 12 having no moisture permeability, such as a film. Reference numeral 13 denotes a thermally conductive filler, which is filled between the side surface 14 of the groove 6 and the side surface 16 of the outer box 2. The condenser pipe 7 is inserted into a part 16 of the bottom corner of the groove 5 and fixed by pressure by the thermally conductive member 5.

Next, the method for forming the above structure will be described in detail. First, a thermally conductive filler 13 is filled between the side surface portion 14 of the groove 6 and the side surface portion 16 of the outer box 2. Next, after inserting the condenser pipe 7 into the groove 6, the sealing heat insulating material 9 is inserted, and the condenser pipe 7 is pressed and fixed to a part 16 of the bottom corner of the groove 5 using a thermally conductive member 11. do. Thereafter, the front flange 8 of the inner box 3 is inserted between the sealing heat insulating material 10 and the front flange 6 of the outer box 2, and the foamed heat insulating material 4 is filled and foamed into the space formed by the outer box 2 and the inner box 3. A refrigerator main body 1 is formed.

Problems to be Solved by the Invention However, in the above configuration, the condenser pipe 7 may not be located at the bottom corner part 16 of the groove 6, and the heat of the condenser pipe 7 may be transferred to the side surface 14 of the groove 6. →Thermal conductive filler 13→Thermal conduction to the side surface 16 of the outer box 2 is not conducted efficiently, and the dispersion of the heat dissipation efficiency of the condenser piping 7 increases. Furthermore, there was a risk that moisture would enter between the front flange 8 of the inner box 3 and the front flange portion 6 of the outer box 2, causing corrosion of the condenser piping 7.

In view of the above-mentioned problems, the present invention enables the condenser pipe to be easily and reliably disposed in a part of the bottom corner of the groove, and also to prevent corrosion of the condenser pipe.

Means for solving the problem The technical means for solving the above problem is to provide a non-moisture permeable thin-walled member having two independent chambers fixed in position, and a sealing insulation material in the first chamber. After the condenser pipes are inserted and fixed into the second chamber, the condenser pipes are inserted into the groove.

Effects According to the present invention, with the above-described configuration, the condenser pipe is reliably installed in a part of the bottom corner of the groove, so that the heat of the condenser pipe is transferred from the side surface of the groove to the thermally conductive filler to the outside. The heat is reliably transmitted to the sides of the box, which not only increases heat dissipation efficiency but also reduces variations. Furthermore, since the entire circumference of the condenser piping is covered with a thin-walled member that is not moisture permeable, corrosion due to moisture intrusion can be prevented.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. Components that are the same as those in the conventional example are given the same numbers and the description thereof will be omitted. In FIG. 1, 17 is a heat insulating material for sealing. The sealing heat insulating material 17 is integrally formed with a compressible heat insulating material 19 and a thermally conductive member 20 such as steel wool.

Reference numeral 18 denotes a thin-walled member such as a film that has no moisture permeability, and the thin-walled member 18 has a first chamber 18a and a second chamber 18 whose positions are fixed.
It has two independent chambers 18b, and a sealing heat insulating material is inserted and fixed in the first chamber 18a. The second chamber 18b is provided at a position facing the bottom corner part 16 of the groove 6, and the condenser pipe 7 is fixed in the second chamber 18b.

After filling the thermally conductive filler 13, the condenser pipe 7 is inserted into the fixed sealing heat insulating material 17'i groove 6, and the condenser pipe 7 is pressed into the bottom corner part 7 of the groove 6. fixed,
After that, seal the front surface 7 langes 8 of the inner box 3 with the sealing insulation material 19.
The foamed heat insulating material 4 is inserted between the front flange 6 of the outer box 2 and the space formed by the outer box 2 and the inner box 3, and is foamed to form a refrigerator body 1'f.

As described above, this embodiment includes a non-moisture permeable thin member 18 having two independent chambers whose positions are fixed,
A sealing heat insulating material 17 integrally formed with a thermally conductive member 2o is placed in the first chamber 18a, and a condenser pipe 7'f is placed in the second chamber 18b.
: After each is inserted and fixed independently, by inserting it into the groove 6 of the outer box 2, the condenser piping 7f and the thermally conductive member 2o are pressed and fixed to a part 16 of the bottom corner of the groove 5. Since the condenser pipe 7 is reliably installed in the bottom corner part 16 of the groove 5, the heat of the condenser pipe 7 is transferred from the side surface 14 of the groove to the thermally conductive filler 13. →The heat is reliably transmitted to the side surface 16 of the outer box, which not only increases the heat dissipation efficiency, but also
Variations can also be reduced. Furthermore, since the entire circumference of the condenser piping is covered with a thin-walled member that is not moisture permeable, corrosion due to moisture intrusion can be prevented.

Effects of the Invention As described above, the present invention includes an outer box, an inner box inside the outer box, a foam insulation material filled between the inner boxes, and a groove formed in the front 7 flange portion of the outer box. The front 7 flange of the inner box to be inserted into this groove, the sealing heat insulating material integrally formed with a soft thermally conductive member to be inserted in pressure contact between the side surface of the groove and the inner flange surface, and the groove. and a condenser pipe inserted into the bottom part, and the sealing heat insulating material and the condenser pipe are inserted and fixed into a non-moisture permeable thin-walled member having two independent chambers whose positions are fixed in advance. Since it is configured to be inserted into the groove, the installation position of the condenser piping can be identified, and variations in heat dissipation efficiency can be reduced, and moisture can be prevented from entering the condenser piping section. , corrosion of condenser piping can be prevented.
