• calculating a remaining running time of the washing program by subtracting a current running time of the washing program from a preset running time of the washing program;
• judging whether the remaining running time of the washing program is smaller than or equal to a preset first time threshold;
• if the remaining running time is larger than the preset first time threshold, keeping the clothing dryer in a powered-on state;
• and
• if the remaining running time is smaller than or equal to the preset first time threshold
• matching the clothing dryer with a drying program corresponding to the material and/or type of the clothing;
• preheating the clothing dryer according to the drying program;
• determining whether the washing program has ended based on the preset running time;
• if the washing program has ended, sending a prompt message by the reminder device to remind the user that the clothing can be dried;
