rotating drum 2 rotates there is little difference between the case in which the air inlet section 10 a is arranged at the left upper portion of the rear panel 10 and the case in which the air inlet section 10 a is arranged at the right upper portion of the rear panel 10 now the operation and effect of the clothes drying apparatus provided with the air inlet section 10 a in accordance with this embodiment of the present invention will be described in detail first the user puts clothes to be dried into the rotating drum 2 and then closes the door 13 when the user subsequently operates the clothes drying apparatus the drive motor 4 exhaust fan 12 and heater 11 are energized and the rotating drum 2 is rotated at low speed simultaneously ambient air around the housing 1 is introduced into the intake duct 7 with the rotation of the rotating drum 2 the clothes are sequentially upwardly raised from the bottom of the rotating drum 2 by the lifters 20 and then dropped from the top of the rotating drum 2 onto the bottom thereof the air introduced into the intake duct 7 is heated by the heater 11 and then fed to the rotating drum 2 through the through holes 10 b of the air inlet section 10 a of the rear panel 10 that is ambient air is heated by the heater 11 while passing through the intake duct 8 and is then.
