Automatic washing machine with energy recovery arrangement

摘要

A mains water inlet circuit (7) is connected to the washing vessel (1) of the machine through a first and a second pipe branch (8, 9) that are adapted to be opened selectively by means of valves (10, 12, 13). In series with the first pipe branch (8) there is connected a reservoir (11) arranged in a heat-exchange relationship with the vessel. During the washing phase of the cycle, this reservoir (11) is filled with mains water that is delivered into the tub (1), in view of carrying out a hot rinsing phase, only after a cold rinsing phase.
