<P>PROBLEM TO BE SOLVED: To provide a refrigerator that is improved in cooling efficiency and reduced in power consumption by suppressing the heat absorption quantity of a surface of an outer box. <P>SOLUTION: The refrigerator includes: a heat insulation box 101 which comprises an inner box 103 and an outer box 102 and is provided with a heat insulator between the inner box 103 and outer box 102; a lower machine room 107 constituted below the heat insulation box 101; a compressor 108 installed in the lower machine room 107; a heat insulation door 119 which opens and closes an opening front of the heat insulation box 101; and a storage compartment 106 which is formed with the heat insulation box 101 and heat insulation door 119 and has a plurality of temperature zones that are different from one another. A projection shape 129, which suppresses heat absorption from natural convection of high temperature generated from a surface of the compressor 108 which becomes higher in temperature than the outside air during operation, is provided on a surface of the outer box 102 of the heat insulation box 101 in which the natural convection circulates. Consequently, there is provided the refrigerator which is reduced in heat absorption quantity from the surface of the outer box 102 and thereby improved in cooling efficiency to have a small power consumption. <P>COPYRIGHT: (C)2013,JPO&INPIT |
