PURPOSE:To mount the bottom section of a cooler onto a flat surface, and to reduce the space of a top wall and an outer box by installing a drain pipe to the bottom section of the cooler so as to be penetrated into the top wall and led out to the outside of the outer box through a storage chamber. CONSTITUTION:A drainage system 15 connected to a refrigerator 14 is penetrated into a top wall 3 and introduced into a storage chamber 10, and led out to the outside of a heat-insulating outer box 2. Consequently, when the refrigerator 14 is used for refrigeration, the drainage system 15 is not exposed at a minus temperature, drain passed through the drainage system 15 or stored in the drainage system 15 is not frozen, and a drain path in the drainage system 15 is not closed. The drainage system 15 is pentrated into the top wall 3, and led out to the outside of the outer box 2 through the storage chamber 10. Accordingly, a section projected from the bottom section of the cooler 14 is removed, the bottom section of the cooler 14 can be placed onto a flat surface while the required height of a cold-air curculating space is inhibited, and the space of the top wall 3 and the outer box 2 can be reduced. |
