Abstract
In a washer dryer in which a drum supported by a spider is rotatable in a tub, the rear wall of the tub is contoured such as by providing castellation-like recesses, and water may be fed over this rear wall via a water inlet so that, in a drying mode, when the drum is rotated and moist air is drawn from the drum, the moist air is agitated by being dragged by the rotation of the drum past the tortuous profile over which water is trickled, to promote efficient condensation before the air is heated and returned to the drum in a recirculating path.
Claims13
A washer-dryer machine for washing and drying a load during respective washing and drying cycles, comprising:
- a) a tub having a tub wall;
- b) a drum for receiving the load and mounted in the tub for rotation about an axis, the drum having a drum wall spaced from, and bounding with, the tub wall a condensing region through which moist air from the drum is drawn during the drying cycle for moisture removal;
- and
- c) a plurality of raised regions and a plurality of recessed regions on a surface of the tub wall that faces the drum wall, the raised and recessed regions alternating with one another in a circumferential direction about the axis.
