Abstract

A laundry washing machine (1) has an outer casing (2) and, inside the outer casing (2), a washing tub (3), a detergent dispensing assembly (9) structured for supplying detergent into the washing tub (3), and a fresh-water supply circuit (10) structured for selectively channeling a flow of fresh water from the water mains towards the detergent dispensing assembly (9) and/or the washing tub (3). A water softening device (12) is arranged/located along the fresh-water supply circuit (10) and is structured for reducing the hardness degree of the fresh water channeled to the detergent dispensing assembly (9) and/or the washing tub (3). The water softening device (12) being internally provided with a given amount of water softening agent able to reduce the hardens degree of the fresh water flowing through the same water softening device (12), and with a given amount of consumable regeneration agent, able to regenerate the water softening function of the water softening agent. The laundry washing machine (1) further has an appliance control panel (11) located on a front wall (2a) of the casing (2), close to a worktop (2b) of the casing (2), and structured for allowing the user to manually select the desired washing-cycle. The water softening device (12) being provided with a loading inlet or mouth (33a, 52) structured for allowing the user to load a regeneration agent inside the same internal water softening device (12) and arranged/located inside the casing (2) so that its loading inlet or mouth (33a, 52) is exposed or exposable to the outside on said worktop (2b) of the casing (2), substantially behind the appliance control panel (11).

Claims

1. A laundry washing machine comprising an outer casing having a front wall and an appliance control panel located on the front wall, close to a worktop of the casing, and, inside said outer casing, a washing tub, a rotatable drum housed in axially rotatable manner inside the washing tub and structured for housing the laundry to be washed, a detergent dispensing assembly which is structured for supplying detergent into the washing tub, a fresh-water supply circuit which is structured for selectively channeling a flow of fresh water from a water mains towards the detergent dispensing assembly and/or the washing tub, and a water softening device which is arranged/located along the fresh-water supply circuit and is structured for reducing the hardness degree of the fresh water channeled to the detergent dispensing assembly and/or the washing tub;

the detergent dispensing assembly arranged/located inside the casing so that loading inlet of the detergent dispensing assembly is exposed or exposable to outside of the front wall of the casing substantially beside the appliance control panel;

the water softening device in turn comprising a water-softening agent container which is arranged/located along the fresh-water supply circuit and is filled with a water softening agent able to reduce the hardness degree of the fresh water flowing through the same water-softening agent container, and a regeneration-agent reservoir which is fluidly connected to the water-softening agent container and is structured to receive a consumable regeneration agent for performing a regeneration of a water softening function of the water softening agent stored into the water-softening agent container; and

the laundry washing machine wherein the appliance control panel is structured for allowing the user to manually select a desired washing-cycle, wherein the regeneration-agent reservoir is provided with a loading inlet structured for allowing the user to load a regeneration agent inside the same regeneration-agent reservoir and is arranged/located inside the casing so that said loading inlet is exposed or exposable to outside of the casing and is located/arranged on a portion of said worktop located immediately behind the appliance control panel.

2. The laundry washing machine according to claim 1, wherein the loading inlet of the regeneration-agent reservoir is freely accessible by the user through a manually-operated closure assembly provided on the worktop of the casing.

3. The laundry washing machine according to claim 2, wherein said manually-operated closure assembly comprises a door provided on the worktop of the casing;

said door being movable to and from a closing position wherein the door hides the loading inlet of the regeneration-agent reservoir.

4. The laundry washing machine according to claim 3, wherein said door forms a portion of the worktop of the casing.

5. The laundry washing machine according to claim 3, wherein the worktop of the casing is provided with an inner shelf which is arranged beneath the door, and the loading inlet of the regeneration-agent reservoir is located/incorporated into said inner shelf.

6. The laundry washing machine according to claim 1, wherein the appliance control panel is located substantially beneath the worktop of the casing, substantially on an upper corner of the front wall of said casing.

7. The laundry washing machine according to claim 1, wherein the detergent dispensing assembly is provided with a corresponding loading inlet of the detergent dispensing assembly which is structured for allowing the user to load the washing agent inside the same detergent dispensing assembly.

8. The laundry washing machine according to claim 7, wherein the detergent dispensing assembly comprises a detergent container which is fillable with a given quantity of detergent, softener and/or other washing agent, and which is housed inside the casing into a corresponding container housing;

the front wall of the casing being provided with a corresponding pass-through opening through which the detergent container is accessible by the user.

9. The laundry washing machine according to claim 8, wherein the detergent dispensing assembly comprises a detergent drawer which is manually fillable with a given quantity of detergent, softener and/or other washing agent, and is fitted/inserted in manually extractable manner into a recessed drawer housing which extends inside the casing while remaining above the washing tub, and communicates with an outside of the casing via a front opening realized on the front wall of the casing beside the appliance control panel.

10. The laundry washing machine according to claim 1, wherein the water softening device further comprises a water supply circuit which is structured for channeling a given amount of fresh water into the regeneration-agent reservoir so to at least partly dissolve the regeneration agents stored therein to form some brine.

11. The laundry washing machine according to claim 1, wherein the water softening device further comprises a pump assembly or valve assembly which is interposed between the water-softening agent container and the regeneration-agent reservoir, and which is structured for regulating/ controlling the outflow of brine from the regeneration-agent reservoir to the water-softening agent container.

12. The laundry washing machine according to claim 1, wherein the regeneration-agent reservoir comprises a substantially basin-shaped, regeneration-agent container having a mouth which is manually fillable with a given quantity of consumable regeneration agent, and is recessed/incorporated into the worktop of the casing on a portion of the worktop located behind the appliance control panel, so that the mouth of the regeneration-agent container is freely accessible by the user.

13. The laundry washing machine according to claim 12, wherein the regeneration-agent container is recessed/incorporated into an inner shelf of the worktop behind the appliance control panel, so that the mouth of the regeneration-agent container is freely accessible by the user through a manually-operated closure assembly.

14. The laundry washing machine according to claim 12, wherein a water supply circuit of the water softening device is structured for spilling/pouring a shower of water droplets by gravity into the substantially basin-shaped container of the regeneration-agent reservoir.

15. The laundry washing machine according to claim 1, wherein the regeneration-agent reservoir comprises:

a storage tank which is structured for being manually fillable with a given quantity of consumable regeneration agent, and which is arranged/located immediately underneath the worktop of the casing, so as to be freely accessible by the user from the worktop of the casing; and
