The control method of the dryer according to any one of claims 1 to 3, wherein the dryer continues heating when the condensing temperature of the dryer reaches a preset condensing temperature, by adjusting the rotation speed of the fan so that the temperature difference between the adjusted condensing temperature and the temperature of the tub is not greater than the preset temperature difference, comprising the steps of:
judging whether the current condensation temperature reaches the preset condensation temperature, if so, continuing to heat the clothes dryer and judging whether the temperature difference between the current condensation temperature and the temperature of entering the barrel is greater than the preset temperature difference, and if so, adjusting the rotating speed of the fan so that the temperature difference between the adjusted condensation temperature and the temperature of entering the barrel is not greater than the preset temperature difference.
6. The control method of the dryer according to claim 5, wherein the dryer dries the laundry at the adjusted rotation speed of the compressor and the adjusted rotation speed of the fan.
7. The control method of the dryer of claim 5, wherein the judging whether the temperature difference between the condensing temperature and the tub entering temperature is greater than a preset temperature difference comprises:
and detecting and judging whether the temperature difference between the current condensation temperature and the barrel entering temperature is greater than a preset temperature difference every preset time t 2.
8. The control method of the dryer according to claim 4, wherein the temperature increase rate of the condensing temperature is (current condensing temperature-condensing temperature after last adjustment)/preset time t 1.
9. The control method of the clothes dryer according to any one of claims 1 to 3, wherein the adjusted rotation speed of the fan is not higher than a preset maximum fan rotation speed.
10. A clothes dryer characterized by being controlled by the control method of the clothes dryer according to any one of claims 1 to 9.
