Abstract

1406155 Dishwashers TAPPAN CO 8 May 1973 21897/73 Heading A4F [Also in Division H2] In a dishwasher, an electric motor 13 e.g. a split phase or shaded pole type induction motor drives an impeller 58 thereby forcing cleaning fluid in sump 12 to a spray arm mechanism 22 in tub 11, and also serves to heat the fluid. As shown by the arrows, the fluid circulation path is through apertures 31 along the gap between plates 25, 16 which separate the sump 12 and tub 11, and through inner apertures 19 passing then through apertures in the motor rotor 48. The rotating impeller 58 drives the fluid past the stator 36 energized by windings 41 which may be housed in a heat conducting jacket 64, Fig. 3 (not shown), substantially filled with a liquid dielectric for example transformer oil. The fluid enters the spray mechanism 22 via tubes 21 within which it crosses the fluid path from the tub 11. The dimensions of the laminations of the rotor 48 and stator 36 are chosen to generate sufficient heat to maintain the fluid within the temperature range 145‹-165‹F.
