<p>A washing machine (10) for objects comprises a chamber (18) in which the objects are washed and rinsed in sequence, a washing unit (50) suitable to feed a washing liquid heated to a first temperature to said chamber (18) and comprising a first tank (11) for the washing liquid, with which first heating means (26) are associated suitable to heat the washing liquid to the first temperature, a feed circuit (52) suitable to supply a rinsing liquid at a second temperature, lower than the first temperature. The washing machine (10) also comprises a rinsing unit (51) suitable to feed the rinsing liquid received from the feed circuit (52)} heated to a third temperature, greater than the second temperature, advantageously greater than the first temperature too, to the chamber (18). The rinsing unit (51) comprises a second tank (12) for the rinsing liquid, with which second heating means (27) are associated, suitable to heat the rinsing liquid to the third temperature. The washing machine (10) comprises recirculation means (53) to recirculate the liquid used in the chamber (18) to the washing unit (50). Heat exchange means (28, 29) are provided in cooperation between the washing unit (50) and the rinsing unit (51) in order to carry out, directly or indirectly, a heat exchange between at least the liquid which is recirculated by the recirculation means (53) and at least the rinsing liquid from the feed circuit (52) which is fed to the rinsing unit (51),</p> |
