Clothes dryer and control method thereof

The embodiment of the invention provides a clothes dryer and a control method thereof and relates to the field of home appliances. The clothes dryer can improve clothes drying condition determining accuracy. The concrete scheme is that changes of a target temperature difference delta T are monitored; the target temperature difference delta T=NTC2-NTC1, wherein NTC2 is an air temperature value after heating, and NTC1 is an air temperature value after condensation; and when it is determined that the target temperature difference delta T is larger than or equal to a first preset threshold, a heater is shut down. The control method is used for manufacturing of the clothes dryer. 本发明的实施例提供种干衣机及其控制方法，涉及家电领域，能够提高对衣物烘干情况的判定准确性。具体方案为：监测目标温差ΔT的变化；目标温差ΔT＝NTC2-NTC1，其中NTC2为加热后的空气温度值，NTC1为冷凝后的空气温度值；当确定目标温差ΔT大于或者等于第预设阈值时，关闭加热器。本发明用于干衣机的制造。
