Abstract

PURPOSE:To provide an anchor which produces the effect of a reinforcing material against longitudinal expansion of an inner case and enables execution of resistance against the vaporizing pressure of R-11 during the long term stop period of a refrigerator, by a method wherein an anchor approximately in a U-shape is mounted on the heat insulating material side of the inner box, and the inner box is filled with a heat insulating material for foaming. CONSTITUTION:Anchors 18 and 19 approximately in a U-shape are mounted on the heat insulating side of an inner box 12, and cooling pipes 14 are disposed. By securing the inner box 12, the cooling pipes 14, and the anchors 18 and 19 to each other by means of pipe presses 15, 16, and 17, expansion of the inner box 12 toward the inner side of a chamber can be prevented from occurring even when a refrigerator is operated and stopped for a long time. Especially, the U-shaped part of the anchor is embedded in a foamed heat insulating material, even when vaporizing expansion of liquefied R-11 takes place, the U-shaped part of the anchor forms hook, and the inner box 12 is hard to be peeled away from the pipe presses 15, 16, and 17, and expansion toward the inner side of a chamber is prevented from occurring.

た。Problems to be Solved by the Invention However, with the above configuration, the refrigerant in the cooling pipe 4 evaporates at around 130 tE and becomes low temperature, so R-11, etc. used as a foaming agent in the foam insulation material cools the pipe 4. It gathers around the gap between the pipe 4 and the pipe holder 5 in a liquefied state. In such a case, when you move or in winter, if you feel that the refrigerator is no longer needed, turn off the power to the refrigerator.When the inside temperature of the refrigerator becomes the same as the outside temperature, the above-mentioned liquefied R-ll etc. will vaporize and its volume will expand, causing the inner box 2 to become larger as shown in 6. It expands like this. As a result, there were problems such as insufficient cooling in the refrigerator and continuous operation of the compressor due to insufficient heat sensitivity of the thermostat, resulting in wasted electricity, as well as aesthetic defects on the inner surface of the inner box.

本発明は上記問題点に鑑み、運転を長期間停止しても内

るものである。In view of the above-mentioned problems, the present invention provides a refrigerator whose inner box does not separate from the cooling pipe and does not expand even if the refrigerator is not operated for a long period of time.

The structure is such that a pipe holder is attached to the inner box, cooling pipe, and anchor from above by gluing, etc., and then filled with foamed heat insulating material.

This prevents the inner box from becoming stuck and peeling off from the pipe holder and expanding toward the inside of the refrigerator even if it is expanded by vaporization such as -ll.
