It is described a dishwashing machine embodying the alternated supply oft the rotating collectors without any devices external to the inlet and water pumping pipes. Said pumping means being formed by two superimposed and communicating pressure chambers (7, 10) inside which two centrifugal complementary impellers (14, 15) are fitted, that is, having their paddles directcd toward opposits direction, both splined to the shaft of an electric motor, commanded by a programmer (18), so that when the shaft turns in a first direction it activates the first centrifugal impeller and supplies a first rotating collector, and when it turns in the opposite direction activates the second centrifugal impeller and supplies a second rotating colletor. In a variation the two complementary impellers are replaced by a single en bloc double impeller. |
