 wherein, generating of steam is paused when a water level in the water box is detected to be lower than a low water level set value H 1  in a process of generating steam; water is supplemented to the water box through a water supplementing hole; generating of steam is restarted when the water level is higher than or equal to the low water level set value H 1 ; and water supplementation is stopped when the water level in the water box reaches a high water level set value H 2 ;   or, the steam generator comprises two water source pipes and one air injection pipe; a first water source pipe in the two water source pipes is connected to the water box unit, and a second water source pipe in the two water source pipes is connected to the external water source; the first water source pipe is turned off and the second water source pipe is turned on when the water level in the water box is detected to be lower than the low water level set value H 1  in a process of generating steam, and water is supplemented to the water box through the water supplementing hole while the steam generator continues to generate steam; and the first water source pipe is turned on and the second water source pipe is turned off when the water level in the water box is higher than or equal to the low water level set value H 1 , and water in the water box unit is reused for generating steam.   
     
     
         8 . The method according to  claim 7 , wherein a controller gives prompt information that the water box is full when the water level in the water box is higher than the high water level set value H 2 , and the clothes dryer stops operating. 
     
     
         9 . The method according to  claim 7 , wherein water supplementation is stopped when the steam generator stops generating steam in a process of supplementing water to the water box through the water supplementing hole. 
     
     
         10 . The method according to  claim 7 , wherein generating of steam is stopped when the steam generator sprays the steam for the preset time T in a process of supplementing water to the water box through the water supplementing hole, and meanwhile, water supplementation is stopped. 
     
     
         11 .
