キ音も出ない。 The rotation of the drum 3 is controlled by a rear bearing structure.
The synthetic resin disk body 20 fixed to the drum 3 serves as a rotating shaft and rotates within the circular recess 16 of the support plate 15, thereby smoothly performing the rotation. Furthermore, the disk body 2
0 is locked at the end of the circular hole 17 and does not come out of the recess 16, and since the support plate 15 is firmly fixed to the rear surface 1a of the outer box 1 and other parts, the rotating drum 3 swings back and forth. There is no rattling sound.
フアン４により半導体ヒーター５で加熱された
空気は、ダクト７の側端７ｂからドラム３内に送
り込まれる被乾燥衣類を乾燥させる。 The air heated by the semiconductor heater 5 by the fan 4 dries the clothes to be dried, which are sent into the drum 3 from the side end 7b of the duct 7.

できるものである。 As described above, the bearing at the rear of the clothes dryer drum of the present invention rotatably supports the drum within the outer box, and the heater for sending hot air into the drum.
In a clothes dryer equipped with a fan, the drum support plate is partially bulged out to form a circular recess, and a synthetic resin disc fixed to the center of the back of the drum is rotatably housed within the circular recess. Unlike the spherical bearings, it can accept a large diameter synthetic resin rotating shaft as the rotating drum shaft. As a result, eccentricity and vibration caused by rotation of the drum can be suppressed as much as possible.
