A clothes dryer is provided to reduce dry time and energy by heating up the internal air with heaters and circulating the heated air along a spiral path formed on an inner wall of a housing. A clothes dryer has a hot blast treating chamber(10) at a lower part and has a drying chamber(20) at an upper part. In the hot blast treating chamber, a cooling unit(11), a first heater(13), a second heater(15), and a blower fan(17) are connected in series. A hot blast suction path(3) has one end connected to the lower part of a hot blast suction port(21) formed at an upper part in the drying chamber and the other end connected to an upper part of the cooling unit. The other end of a hot blast injection path(4) is assembled to a lower part of the blower fan. A first hot blast injection port(30) and a second hot blast injection port(40) are formed at two sides of a lower part of the drying chamber. The hot blast injection path is assembled to upper parts of the first and second hot blast injection ports. A drain pipe(51) is connected to the lower parts of the drying chamber and the cooling unit. A water tray(53) connected to the drain pipe is installed at the hot blast treating chamber. A spiral path(6), formed at an inner wall of the drying chamber, guides internal air upward. |
