PURPOSE: To heighten an effect of draft by providing a dust on the back of a refrigerator whose upper part opens near the roof and lower end locates below a compressor's upper part in such a manner as to cover it, thereby causing heat to flow into the duct naturally and increase buoyancy.
CONSTITUTION: Heat released from a condenser 10 rises higher than ducts 5a 5c due to natural convection by air coming in from an air intake 17 of the under surface orthogonally to the condenser 10 and is released. Also, position changes of lower end 22 of a duct 5 causes draft force of heat in the duct 5 to be changed. Heat released from a compressor 9 and the condenser 10 goes into the duct 5 along one or a plurality of ducts 5 and rises in the duct 5, which then gathers high temperature air passed through the compressor 9 and condenser 10. Thus occurred natural convection produces much more draft effect than a conventional refrigerator which releases heat from a machine room by natural convection, resulting in heat release of a machine room.
