Abstract

Clothes washing machine comprising: a common water-distribution manifold, a plurality of electromagnetic valves provided downstream of said water-distribution manifold and connected on respective outlet conduits, a plurality of chambers supplied via a respective one of said outlet conduits, a further chamber supplied with a water flow generated by the intersection of said outlet conduits, wherein a nozzle lodged in a bellows is supplied with a water flow a fully separated fifth conduit having a respective air-gap and starting from one of said valves; the initial portions of said outlet conduits, upstream the air-gaps, are a single en bloc body, which is realised in a single item together with the assembly of the water flat conveyors downstream the air-gaps.

Claims

1. Clothes washing machine comprising:

a drum for holding the clothes to be washed,

a bellows (21),

a common water-distribution manifold (2),

a plurality of electromagnetic valves (3b, 4b) arranged downstream of said water-distribution manifold and connected on a respective inlet side thereof to said common water-distribution manifold (2),

a plurality of outlet conduits (3, 4) provided at the delivery ports or respective ones of said electromagnetic valves,

a respective plurality of chambers (3a, 4a) provided to contain washing products, rinsing aids and similar substances, each one of said chambers being supplied via a respective one of said outlet conduits (3, 4),

a (cold-)water inlet conduit (6) directly connecting the (low-temperature) water supply system to said water-distribution manifold (2),

a (hot-)water inlet conduit (7) connecting the high-temperature water supply system to a predetermined one (3) of said outlet conduits downstream of the respective electromagnetic valve (3b),

a further electromagnetic valve (7b) installed in said (hot-)water inlet conduit (7) upstream of the point at which the latter connects with said pre-determined outlet conduit (3),

a further chamber (12) that is supplied with a respective water flow directed from a fourth outlet conduit (11) and generated by the intersection (10) and physical impinging between the two water-flows in said two outlet conduits (3, 4), characterized in that;

the initial portions (33, 34) of said outlet conduits (3, 4) are a single en bloc body (13), which delimits, on the same side, both the two water flows in the respective outlet conduits (33, 34) before said intersection (10),

a fifth conduit (15) is branched out from a port (Q) emerging from said en bloc body (13), close and downstream to one (3b) of said outlet valves (3b, 4b), said fifth conduit (15) being fully separated from said en bloc body (13), and directs a respective water flow to a nozzle means (20) lodged into said bellows (21).

2. Clothes washing machine according to claim 1, characterized in that said two outlet conduits (3, 4) are directed towards respective flat conveyers made as an en bloc, and that between said en bloc flat conveyers and said en bloc body (13) a separation trench (16) is placed, whereon said intersection (10) is located.

3. Clothes washing machine according to claim 2, characterized in that said single en bloc body (13) and said en bloc flat conveyers are made up as a fully integrated en bloc item (18), and that said separation trench (16) is an empty portion placed internally of said fully integrated en bloc item (18).

4. Clothes washing machine according to claim 1, characterized in that said fifth conduit (15) is being supplied with a respective air-gap (15S).

5. Clothes washing machine according to claim 1, characterized in that said fifth conduit (15) is fully and physically separated from said integrated en bloc item (18).
