132 and s 133 hence the controller 300 controls a pair of drying heater 141 and 142 to generate hot air especially the pair of the drying heaters 141 and 142 is controlled to radiate heat differently based on the operation object for example once the operation object is identified as the tumble dryer 100 or as a simultaneous operation of the tumble dryer 100 and the cabinet dryer 200 the controller 300 controls the pair of the drying heaters 141 and 142 to be on s 141 for gaining the maximum output of 5400 watt thereby a smooth drying cycle is possible in case that the operation object is identified as the cabinet dryer 200 only one drying heater 141 is controlled to be on s 141 for gaining a relatively small output of 2700 watt that is why the operation of the cabinet dryer 200 is not for an actual drying cycle but for a refreshing or a laundry keeping that is only one drying heater is on because the operation temperature may be lower than the operation temperature for drying the laundry also as described above due to the selective radiation of each drying heater 141 and 142 the temperature within the second supplying pipe 132 maintains high at that time since the fan 150 drives air within each pipe 131 132 and 133 of the hot air supplying pipe 130 is forcibly ventilated the hot air changed hot by the drying heaters 141 and 142 is flown along each hot air supplying pipe 131 132 and 133 to be consistently supplied into the drying drum 120 of the tumble dryer 100 and or the keeping part 220 of the cabinet.
