Clothes dryer and method for controlling operation thereof

A method of controlling operation of a clothes dryer, the clothes dryer including a circulation fan for circulating air and a cooling fan being separately driven to cool down a condenser, the method comprising processes of:

• simultaneously rotating the circulation fan and a drum, and operating a heater in a state of the cooling fan being stopped;
• and
• beginning to rotate the cooling fan when a predetermined condition is met so as to delay operation of the condenser for improving drying efficiency, wherein the cooling fan is rotated when a temperature of circulating air reaches a predetermined degree.

• and
• beginning to rotate the cooling fan when a predetermined condition is met so as to delay operation of the condenser for improving drying efficiency, wherein the amount of heating of the heater is variable and the cooling fan is operated at a low speed when the amount of heating of the heater is a first set value (Q1) and less.

• and
• beginning to rotate the cooling fan when a predetermined condition is met so as to delay operation of the condenser for improving drying efficiency, wherein the amount of heating of the heater is variable and the cooling fan is operated at a regular speed when the amount of heating is between the first and second set values (Q1 and Q2).
