Abstract

PURPOSE:To efficiently transmit the heat of a dewing preventing pipe to a partition plate and make the partition plate rigid by pouring foaming heat insulating material from a filling space through a communication hole into a partition body for the expansion therein. CONSTITUTION:A foaming heat insulating material is poured into a filling space 42 between an outer case 12 and an inner case 14 of a refrigerator body 11. Since the filling space 42 communicates with the interior of a partition body 31 through a communication hole 40, the foaming heat insulating material is allowed to flow from the filling space 12 through the communication hole 40 and then through an inlet hole 56 of a pipe retaining part 54 into the partition body 31, which is the filled thoroughly with the foaming heat insulating material for the expansion thereof. By filling the partition body 31 with the foaming heat insulating material in this way, the inner space thereof can be completely eliminated and the dewing preventing pipe 52 can be accurately urged against the rear surface of a partition plate 46 by the expansion of the foaming heat insulating material, whereby the heat dissipating from the dewing preventing pipe 52 can be effectively transmitted to the partition plate 46 to improve the dewing preventing performance.

An object of the present invention is to provide a refrigerator provided with a partition body which can efficiently transfer the heat of the dew-proof pipe to the partition plate and which has excellent rigidity.

[0009]

In the refrigerator of the present invention, a refrigerator main body is constituted by an outer box and an inner box which is combined with the outer box through a space filled with a heat insulating material. The partition body is vertically divided by one or a plurality of partition members, and at least one of the partition members is horizontally installed at the front end of the refrigerator body and has a dew-proof pipe inside. The partition body is provided with a communication hole connecting the inside of the partition body and the filling space, and a foaming heat insulating material is poured into the partition body from the filling space through the communication hole to foam.

According to a second aspect of the present invention, it is preferable that the depth of the left and right ends of the partition body is larger than that of the central portion.

[0011]

In the refrigerator of the present invention, since the partition body is provided with the communication hole that connects the interior of the partition body with the filling space,
When the foamable heat insulating material is injected into the filling space, the foamable heat insulating material flows into the partition body through the communication hole and foams. Therefore, the inside of the partition body is completely filled with the heat insulating material, and there is no space inside the partition body.

If the depth dimension of the left and right ends of the partition body is made larger than that of the central portion as in the second aspect of the invention, the communication holes are formed on the left and right sides of the partition body as compared with the case where they are of the same size. The depth dimension can be increased when it is provided on the side surface of the. As a result, the foamable heat insulating material can flow into the inner space of the partition body more smoothly, and the filling property thereof is improved.
