Claim 14:
15. A laundry dryer comprising:
a cabinet that defines an exterior of the laundry dryer;
a drum rotatably disposed inside the cabinet and configured to receive an object to be dried;
a duct part configured to guide air discharged from the drum and to supply the air to the drum;
a circulation fan configured to move the air along the duct part;
a heat exchanger disposed at the duct part and configured to perform heat exchange with the air guided along the duct part;
a compressor configured to compress refrigerant that is configured to exchange heat with the air guided along the duct part;
a steam part configured to generate steam and to supply the steam into the drum; and
a controller configured to control the drum, the circulation fan, the compressor, and the steam part,
wherein the controller is configured to, while supplying the steam into the drum through the steam part, rotate the drum and stop rotation of the circulation fan,
wherein the controller is configured to operate the steam part for a preset preheating time to thereby heat water for generating the steam,
wherein the controller is configured to rotate the circulation fan for the preset preheating time, and then stop rotating the circulation fan while spraying the steam through the steam part,
wherein the controller is configured to:
rotate the circulation fan at a first rotational speed for the preset preheating time; and
after spraying the steam through the steam part, operate the compressor and the circulation fan to thereby dry the object in the drum, and

wherein the controller is configured to, after spraying the steam through the steam part, rotate the circulation fan at a second rotation speed that is different from the first rotational speed of the circulation fan.
