(54) | Washing machine with through-flow water heating arrangement |
(57) The washing machine comprises a conduit (9) in which the water is caused to circulate
in a heat-exchange relation with heating means (11). In correspondence of a portion
(12) of the conduit (9), in which there are provided said heating means (11), the
same conduit features a reduced passage cross-section area, in such a manner as to
cause the flow velocity of the water therethrough to increase and the deposit of dirt
and limestone particles suspended in the water to be diminished. |
