  Here, the case where the lid member 17 is not provided in the opening 16 of the drum 10 during such a drying operation will be described with reference to FIG. The generation of wrinkles in the garment W accommodated in the drum 10 can be cited as one of the causes that the garments W are entangled and dried in a twisted state. The tangling of the clothing W and the twisting of the clothing W occur when the clothing W is agitated in the drum 10. Furthermore, if the volume of the garment W accommodated in the drum 10 is large, especially when the garment W increases in volume during the latter half of the drying, the garment W is squeezed from the back of the drum 10 to the door 3. The clothing W on the front side is pressed against the door inner plate 3 b of the door 3. When the drum 10 rotates in this state, the garment W rotates together with the drum 10, but may be caught at a portion in contact with the stationary door inner plate 3 b, and the garment W may be strongly twisted. This is one of the causes of wrinkles.

  In this regard, in the present embodiment, as shown in FIG. 1, the drum 10 is provided with a lid member 17 that closes the opening 16 thereof, so that the clothing on the front side in the drum 10 is temporarily the lid member 17. Even when the cover member 17 is pressed against the back surface, the lid member 17 also rotates integrally with the drum 10, so that it is possible to prevent the clothes from being strongly twisted and to suppress the occurrence of wrinkles themselves. It becomes possible. Thereby, it is possible to improve the dry finish.

  In the present embodiment, the drum 10 includes a rotary balancer 15 having an annular shape at the periphery of the opening 16, and the lid member 17 is attached to the inside of the rotary balancer 15. Since the rotary balancer 15 is normally provided with a synthetic resin balancer container 15a, there is an advantage that a portion for attaching the lid member 17 can be provided relatively easily when the balancer container 15a is molded.

  Furthermore, in this embodiment, since the lid member 17 is attached to the opening 16 inside the rotary balancer 15, for example, the effective space in the drum 10 is larger than when the lid member is provided on the back side of the rotary balancer 15. Can be made as small as possible.

  It is conceivable to attach a lid member that closes the opening 16 of the drum 10 to the door 3 side. However, in order to provide the lid member on the back side of the door 3 so as to rotate integrally with the drum 10, the support structure of the lid member becomes complicated and it is difficult to align the lid member and the opening 16 of the drum 10. In reality, there is a problem that it is difficult. In this respect, by attaching the lid member 17 to the rotary balancer 15 of the drum 10 as in the present embodiment, the support structure of the lid member 17 can be simplified, and the positions of the lid member 17 and the opening 16 of the drum 10 can be simplified. There is an advantage that it can be easily combined.
