A laundry appliance such as a washing machine includes an outer housing and a drum rotatably mounted therein. The drum has an inner wall and an outer wall separate from the inner wall, the inner and outer walls being perforated to allow washing liquid to flow into and out of the drum via the perforations. The area of the perforations per unit area of the outer wall is greater than the area of the perforations per unit area of the inner wall. |
