Description

[Detailed description of the invention] This invention uses the high-pressure side refrigerant of the cooling system to prevent the frosting phenomenon (sweating phenomenon) that occurs on the front panel on the back side of the front panel of the partition wall that divides the refrigerator into two compartments. This relates to a refrigerator that is equipped with a portion of pipes.

The object of the present invention is to simplify the work of attaching the refrigerant pipe to the front panel, that is, the work of assembling the front part of the partition wall.

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

Reference numeral 1 denotes a refrigerator body, which is made up of an outer box 2, an inner box 3, and a heat insulating material (not shown) filled between the boxes 2 and 3.

The inside of the refrigerator body 1 is divided into a freezing compartment 5 and a refrigerating compartment 6 by a partition wall 4.
It is divided into two rooms.

This partition wall 4 is a molded product 10 formed of a foamed heat insulating material 16 that is integrally formed with the bottom plate 7 of the freezer compartment 5, the top plate 8 of the refrigerator compartment 6, the front panel 9, and the high-pressure side refrigerant pipe 14b. It has a cooling chamber 13 in which a cold air passage 11 and an evaporator 12 are installed.

Furthermore, this refrigerator body 1 is equipped with a cooling system consisting of a compressor, a condenser (not shown), an evaporator 12, etc., and a part of this cooling system is provided on the periphery of the opening on the front of the refrigerator body 1 and on the back of the front panel 9. High pressure side refrigerant pipe 14a forming
, 14b are arranged, and this high pressure side refrigerant pipe 14
a and 14b prevent dew from forming due to the temperature difference with the outside temperature.

Next, to explain the molded product 10, the front panel 9
The locking ends 9a and 9a' are inserted between the outer box 2 and the inner box 3 at the periphery of the front opening of the main body on the left and right, and the U-shaped flange at the upper end is locked to the front locking portion 7a of the bottom plate 7. 9b and a folded flange 9c to which the top plate 8 is fixed at the lower end with screws 15.15 are integrally formed.

The refrigerant pipe 14b is installed in contact with the back surface of the panel 9, and a foamed heat insulating material 16 such as urethane is integrally foamed on the back surface of the panel 9 where the refrigerant pipe 14b is installed using an appropriate jig (not shown). The foamed heat insulating material 16 is fixed to the back surface of the front panel 9, and the refrigerant pipe 14b is held in close contact with the back surface of the front panel 9 by the foamed heat insulating material 16.

As is clear from the above description, according to the present invention, the partition wall is constructed by attaching a molded product in which the refrigerant pipe is fixed with foam insulation material, which not only simplifies the assembly work but also allows the high-pressure side Since the refrigerant pipe is completely surrounded by foam insulation material, there is no risk of heat impacting the cooling chamber formed at the rear of the molded product, and a separate partition wall insulation material is provided on the back of the front panel. This is an extremely practical effect that is not necessary.
