Clothes dryer

A clothes dryer, comprising:

• a drum rotatably supported in a case, for drying clothes inserted into the case;
• driving means installed in the case, for rotating the drum;
• a suction duct connected to a side of the drum, for supplying heated air into the drum;
• a heater installed at an inlet side of the suction duct, for heating the air supplied into the drum;
• an exhaust duct connected to another side of the drum, for exhausting the supplied heated air used for drying clothes in the drum;
• first blowing means installed in the suction duct or the exhaust duct, for simultaneously providing air into the drum and also exhausting the air therefrom;
• and
• suction increasing means installed in the case, for blowing air towards an inlet side of the heater, said suction increasing means comprising a suction increasing duct having a second blowing means installed for generating a blowing force and an inlet port positioned at said second blowing means and an exhaust port positioned proximate to a heater which is supplied air from said suction increasing duct and from the drum, for generating a blowing force.
