ABSTRACT:
A dishwasher is disclosed which includes a tub formed of plastic, such as polypropylene, or other heat-deformable material. A heating element for effecting the final drying of the articles in the dishwasher is disposed near the bottom wall of the tub where the heat from the heating element could cause a deformation of the adjacent portion of the bottom wall of the tub. A shallow receptacle is disposed between the heating element and the portion of the bottom wall of the tub in close proximity thereto. The receptacle retains a small amount of the water used in the washing and rinsing operations and the evaporation of this water during the energization of the heating element insures that the temperature of the adjacent bottom wall remains below that at which any damage thereto could occur. Spaced dividers extending transversely of the slope of the bottom wall are provided in the receptacle to insure that water is retained therein over substantially the entire surface of the bottom of the receptacle.
