Abstract
Abstract A clothes washing machine, in particular of the household type, includes a washing tub (1), a drum (2) holding the washload, a water inlet conduit (5) from the water supply mains, an electromagnetic valve (6) provided in the conduit, an offshoot conduit (7) downstream of the electromagnetic valve and an air break (8). A water dispenser (3) is located above a plurality of compartments (4) for holding washing and rinsing agents. A siphon (10) is installed between the compartments and the washing tub, and a conduit (9) is positioned between the siphon and the water dispenser. A second water offshoot conduit (13) is provided with a respective air break (15) and is situated between the electromagnetic valve (6) and the air gap (8), wherein the second water offshoot conduit (13) flows into the conduit (9). The air gap is formed by an interruption through an injector (14) located in a vertical descending section of the second offshoot conduit, whereas water (16) issuing from the injector (14) flows into the conduit (9).
