Abstract

A laundry washing machine (1) is equipped with a treating agents dispenser (20) that includes at least one compartment (23a, 23b, 23c, 23d) adapted to be filled with at least one treating agent. The compartment (23a, 23b, 23c, 23d) has a bottom part (62a, 62b, 62c, 62d) and a side wall (63a, 63b, 63c, 63d) rising from the bottom part (62a, 62b, 62c, 62d). The side wall (63a, 63b, 63c, 63d) superiorly defines a top boundary line (263a, 263b, 263c, 263d). At least one water conveying line (120a, 120b, 120c, 120d) conveys water to the at least one compartment (23a, 23b, 23c, 23d). The at least one water conveying line (120a, 120b, 120c, 120d) includes outlets (29a, 29b, 29c, 29d) facing the at least one compartment (23a, 23b, 23c, 23d) and the outlets (29a, 29b, 29c, 29d) are aligned along a path (273a, 273b, 273c, 273d) which is at least partially adjacent to the top boundary line (263a, 263b, 263c, 263d).

Claims

1. A laundry washing machine comprising:

a) a cabinet supporting a washing drum adapted to receive laundry and a washing tub external to said washing drum;

b) a treating agents dispenser comprising;

1) a drawer having at least one compartment adapted to be filled with at least one treating agent, said at least one compartment comprising a bottom part and a side wall rising from said bottom part, said side wall superiorly defining a top boundary line;

2) a housing positioned above said drawer, the housing having at least one water conveying duct positioned above said side wall of said at least one compartment for conveying water to said at least one compartment;

c) a supply line, fluidly connecting said treating agents dispenser and said washing tub;

d) a control unit for controlling functioning of said laundry washing machine;

wherein said at least one water conveying duct comprises outlets having an inclined portion extending from the duct to a position facing said at least one compartment, said outlets being aligned along a path and being at least partially adjacent to said top boundary line directing said water to flow through said outlets along a water direction having a horizontal component tangentially following said side wall of said at least one compartment.

2. A machine according to claim 1, wherein said outlets are aligned along said path so that the water falling into said compartment touches said side wall and then flows towards said bottom part.

3. A machine according to claim 1, wherein said water direction having said horizontal component is parallel to said side wall.

4. A machine according to claim 1, wherein said water direction has a substantially vertical component which tangentially follows said side wall.

5. A machine according to claim 1, wherein the vertical component of said water direction is substantially parallel to said side wall.

6. A machine according to claim 1, wherein said water direction having said horizontal component is parallel to the horizontal direction of said top boundary line at the point of said top boundary line closest to said one outlet.

7. A machine according to claim 1, wherein said outlets are realized along a portion of a duct which defines said at least one water conveying line.

8. A machine according to claim 7, wherein at least one of said outlets comprises an inclined upstream portion.

9. A machine according to claim 1, wherein each of said outlets comprises an inclined upstream portion.

10. A machine according to claim 8, wherein said inclined upstream portion diverges from the axis of said duct.

11. A machine according to claim 1, wherein said side wall is vertical or substantially vertical, with the dispenser in its operating position in the laundry washing machine.

12. A machine according to claim 1, wherein said compartment comprises at least one curved portion.

13. A machine according to claim 12, wherein said outlets of said at least one water conveying line are arranged along so that at least a quantity of water exiting said outlets is directed towards said curved portion.
