[0002]
[Prior art]
2. Description of the Related Art Conventionally, a washing machine for both dehydration and dehydrating is provided with a rotating tub inside an outer shell such as an outer box, and rotating the rotating tub in a state in which laundry is stored, thereby performing dehydration of the laundry. . When the dehydration is performed, air is also discharged from the rotary tub, and air is sucked into the tub from the outside of the rotary tub, whereby air is passed through the rotary tub. It is known that air passing through the tub touches laundry in the tub to remove the moisture, thereby promoting dehydration of the laundry.
[0003]
However, with regard to the ventilation, no special measures have been taken in the conventional general dehydrating / washing machine, and at most, between the outer box in the outer shell and the cover attached thereto, and between the outer cover and the cover. The outside air is only sucked in from appropriate gaps such as between the lid and the like. For this reason, the inside of the rotating tub is not sufficiently ventilated, and the effect of dewatering the laundry is small, so that only a small effect of promoting the dehydration of the laundry is obtained.
On the other hand, there is one in which a lid is provided with an intake port (see, for example, Patent Document 1).
