PROBLEM TO BE SOLVED: To provide an energy saving type refrigerator capable of suppressing power consumption while improving productivity. ! SOLUTION: An inner box 111 of a refrigerator body is made to be an integral component integrally connected by an upper inner box 115, a lower inner box 116 and a front plate part 117. Rear end parts of the upper and lower boxes are connected with each other by a cylindrical duct member 118 for cold air passage, and urethane foam is filled in the whole area between partition wall parts 115a, 116a of the upper inner box and the lower inner box. Thereby, productivity improves as a partition plate for partitioning the inner box does not need to be incorporated separately. Also, the duct member for connecting the rear end parts of the upper and lower inner boxes each other is formed in a cylindrical shape and the whole area between the partition wall parts other than the cylindrical duct member is filled with urethane foam having a high heat insulating property, so that he |
