Dishwasher with a plurality of washing zones

摘要

The dishwasher has a washing tub (2) divided into two washing zones (10, 11) disposed one above the other and separated by a partition (12). Spraying units are associated to the respective zones to spray washing water on dishes loaded on the zones. The partition has two concavities turned towards bottom with a shape of a portion of cylinder. Each concavity is connected to a lateral surface in contact with a lateral wall (29) of the tub. The connecting surfaces of the partition form a slope inclined towards the back and the bottom of the tub to flow the water towards bottom wall of the tub.
