Further, when carrying the refrigerator, the condenser 55 may be damaged by hitting a wall surface or the like. In order to solve such problems, recently, a so-called clean-back refrigerator is mainly used.

In a clean-back refrigerator, a condenser is provided together with a compressor in a parts room provided in a lower region of a rear surface of the refrigerator main body without being disposed on a rear surface of the refrigerator main body. A refrigerant pipe interconnecting the condenser and the evaporator is disposed between the cooling chamber and the outer casing, and is fixed by a foam filled between the cooling chamber and the outer casing. Then, a clean cover fixed by a screw or the like is connected to the rear surface of the outer casing. The clean cover covers all areas on the rear surface of the outer casing, thereby enhancing the appearance of the refrigerator.

However, in this conventional refrigerator,
Since a separate fixing member such as a screw is used to fix the clean cover to the rear surface of the refrigerator body, it is not easy to fix the clean cover, and there is a problem of an increase in manufacturing cost. In addition, since the fixing member is coupled at a predetermined interval along the edge of the clean cover, noise generated from the refrigerator flows out between the rear surface of the refrigerator main body and the clean cover and flows out to the outside. There is.

[0007]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to fix a clean cover to the rear surface of a refrigerator body without using a separate fixing member in consideration of the above-mentioned conventional problems. An object of the present invention is to provide a refrigerator capable of preventing noise from leaking out.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an internal casing forming a cooling chamber in a refrigerator; the internal casing being arranged outside the internal casing so as to be separated from the internal casing; An outer casing having a plurality of outlet holes formed on a rear surface thereof; a clean cover disposed on a rear surface of the outer casing so as to be separated from the outer casing; and a space between the inner casing and the outer casing and the outer case. A foam material is interposed between the casing and the clean cover to fix the outer casing to the inner casing and fix the clean cover to the outer casing.

A large number of outflow holes are formed in the rear surface of the outer casing. When the foaming material injects a foaming liquid between the inner casing and the outer casing, the foaming liquid flowing out of the outer casing through the outlet hole causes the outer casing and the clean cover to be separated from each other. Filled in between. Accordingly, the clean cover can be fixed to the rear surface of the refrigerator main body without the need for a separate fixing member, and the manufacturing cost of the refrigerator can be reduced.
In addition, outflow of noise from the refrigerator is prevented.
