REFRIGERATOR

摘要

PROBLEM TO BE SOLVED: To effectively prevent heat invading through the bottom part of a heat insulating box by a method wherein the rear part of the bottom wall of the heat insulating box is raised, a machine chamber is constituted outside the bottom wall, a vacuum heat insulating material is formed to be arranged along a shape of the bottom wall of the heat insulating box and allows arranged within the bottom wall. SOLUTION: A refrigerator 1 has a heat insulating box 6 filled with foamed polyurethane heat insulating material 4 between an outer box 2 and an inner box 3 and a machine chamber 56 is formed at a rear outside part of its bottom wall 6A. Then, vacuum heat insulating materials 72 are adhered to both inner surfaces of a side plate of the outer box 2 corresponding to both sides of a freezing chamber 18 and an inner surface of a bottom plate 2B of the outer box 2 corresponding to a lower side of the freezing chamber 18 and the heat insulating materials are buried in the heat insulating material 4. In addition, a vacuum heat insulating material is also adhered to the inner surface of the rear plate 2C of the outer box 2 corresponding to a back side of a cooling chamber 37 at the back side of the freezing chamber 18 and then the heat insulating material is buried in the heat insulating material 4. With such an arrangement as above, a wall thickness of the heat insulated box 6 is made thin and an installing space for the refrigerator 1 is made further reduced and at the same time a heat inputting from the machine chamber 56 outside the bottom wall 6A is efficiently reduced.
