Clothes dryer and control method thereof

The invention relates to a clothes dryer and a control method thereof. According to the clothes dryer and the control method thereof, the clothes dryer comprises a power supply, a start button and a power-on detection circuit; the power-on detection circuit comprises a first signal output end, a second signal output end and a first signal input end, and the first signal output end, the second signal output end and the first signal input end are electrically connected with the start button; AND logic operation is carried out on the waveforms of signals on the first signal output end and the second signal output end to obtain a third waveform, and if the power-on detection circuit detects that the waveform of the signals on the first signal input end is the same as the third waveform, it is determined that the start button is in a closed state, and the clothes dryer is correspondingly in a starting state. According to the clothes dryer, the precision requirement for peripheral circuit devices is low, and the co
