A control method for a clothes dryer that comprises a clothes drying drum, a heat pump system and an electrical heating system, the heat pump system comprises a compressor, a condenser, an evaporator and a throttling device, and the electrical heating system is an electrical heating pipe, wherein the method comprises: controlling the heat pump system and the electrical heating system to work cooperatively, thus allowing the clothes dryer to at least comprise a fast mode, in which the electrical heating pipe is turned on after the compressor is turned on and operated stably; air about to enter the clothes drying drum is controlled to be firstly heated by the condenser of the heat pump system and further heated by the electrical heating pipe, and then to enter the clothes drying drum; and a load of the heat pump system is reduced in an auxiliary condensing manner before the heating pipe is switched off, when the load of the heat pump system is close to the maximum load, characterized in controlling the heat pump system and the electrical heating system to work cooperatively, thus allowing the clothes dryer to also comprise: an energy-saving mode, in which the electrical heating pipe is turned off, and the air about to enter the clothes drying drum is only heated by the condenser of the heat pump system; and a general mode, in which the electrical heating pipe is turned on, the air about to enter the clothes drying drum is firstly heated by the condenser of the heat pump system and further heated by the electrical heating pipe, the electrical heating pipe is turned off when the load of the heat pump system reaches the maximum load or a temperature of the heat pump system reaches a pre-set temperature, and thus the air entering the clothes drying drum is only heated by the condenser of the heat pump system. controlling the heat pump system and the electrical heating system to work cooperatively, thus allowing the clothes dryer to at least comprise a fast mode, in which the electrical heating pipe is turned on after the compressor is turned on and operated stably; air about to enter the clothes drying drum is controlled to be firstly heated by the condenser of the heat pump system and further heated by the electrical heating pipe, and then to enter the clothes drying drum; and a load of the heat pump system is reduced in an auxiliary condensing manner before the heating pipe is switched off, when the load of the heat pump system is close to the maximum load, characterized in controlling the heat pump system and the electrical heating system to work cooperatively, thus allowing the clothes dryer to also comprise: an energy-saving mode, in which the electrical heating pipe is turned off, and the air about to enter the clothes drying drum is only heated by the condenser of the heat pump system; and a general mode, in which the electrical heating pipe is turned on, the air about to enter the clothes drying drum is firstly heated by the condenser of the heat pump system and further heated by the electrical heating pipe, the electrical heating pipe is turned off when the load of the heat pump system reaches the maximum load or a temperature of the heat pump system reaches a pre-set temperature, and thus the air entering the clothes drying drum is only heated by the condenser of the heat pump system. an energy-saving mode, in which the electrical heating pipe is turned off, and the air about to enter the clothes drying drum is only heated by the condenser of the heat pump system; and a general mode, in which the electrical heating pipe is turned on, the air about to enter the clothes drying drum is firstly heated by the condenser of the heat pump system and further heated by the electrical heating pipe, the electrical heating pipe is turned off when the load of the heat pump system reaches the maximum load or a temperature of the heat pump system reaches a pre-set temperature, and thus the air entering the clothes drying drum is only heated by the condenser of the heat pump system.
