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 in a fifth conduit having a respective air-gap and starting upstream of said intersection; the initial portions of said outlet conduits and of the fifth conduit, upstream the air-gaps, are a single enbloc body, which is connected to the assembly of the water flat conveyors and of said fifth conduit 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 of 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 pre-determined 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), characterised in that;

said bellows (21) comprises nozzle means (20) to direct a jet of water coming from a fifth conduit (15) derived from a point (P) in one (3) of said outlet conduits, downstream the connection with said third conduit (7), but upstream said intersection (10) between said outlet conduits (3, 4),

said fifth conduit (15) is supplied with a respective air-gap (15S),

and the initial portions (33, 34, 315) of said outlet conduits (3, 4) and of said fifth conduit (15) are a single enbloc body (13), which delimitates, on the same side, both the two water flows in the respective outlet conduits (3, 4) before said intersection (10), and said air-gap (15S) of said fifth conduit (15).

2. Clothes washing machine according to claim 1, characterised in that said two outlet conduits (3, 4) are directed towards respective flat conveyers made as an enbloc, which comprises the portion of said fifth conduit (15) downstream the respective air-gap (15S).

3. Clothes washing machine according to claim 2, characterised in that between said enbloc flat conveyers and said enbloc body (13) a separation trench (16) is placed, wherein both said intersection point (10) and said air-gap (15S) of said fifth conduit (15) are located.

4. Clothes washing machine according to any of the preceding claims, characterised in that said single enbloc body (13) and said enbloc flat conveyers are made up as a fully integrated enbloc item (18), and that said separation trench (16) is an empty portion placed internally of said fully integrated enbloc item (18).
