Abstract
A dishwasher construction having a molded one piece tub with integrally molded reinforcing ribs on an outside surface of the tub, the reinforcing ribs being hollow members formed by gas injection molding. At least one of the reinforcing ribs can be fashioned as a hollow conduit for transferring water from a bottom mounted pump to a top mounted wash arm of the dishwasher, or from a drain pump to a drain outlet. By using hollow reinforcing members molded integrally with the tub, an external upper wash arm conduit is avoided which can have external leakage, and an internal upper wash arm conduit is avoided which tends to restrict the working space within the dishwasher and can trap food and be otherwise functional and unappealing to the consumer.
