ABSTRACT:
An article washing apparatus is provided which has a washing chamber and a heating element spaced upwardly from the bottom wall thereof. Apparatus is also provided for distributing washing liquid within the washing chamber including a pump associated with the bottom wall of the washing chamber and a rotatable horizontally elongated thermoplastic wash arm in communication with the pump to effect washing of the articles by spraying liquid thereon. The thermoplastic wash arm is protected from heat radiated by the heating element by at least one generally U-shaped heat reflecting member supported on the rotatable thermoplastic wash arm. The heat reflecting member is positioned between the thermoplastic wash arm and the heating element with a wall portion of the heat reflecting member spaced from the thermoplastic wash arm and providing an air gap therebetween. The wall portion of the heat reflecting member effectively dissipates and reflects radiant heat from the heating element.
