Abstract

A laundry washing machine ( 1 ) having 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 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 regenerate the water softening function of the water softening agent. The laundry washing machine ( 1 ) further having an appliance control panel ( 11 ) structured for allowing the user to manually select the desired washing-cycle and located/arranged on front of a drawer-like supporting structure ( 13 ) fitted/inserted in extractable manner into the front wall ( 2 a ) of the casing ( 2 ), so as to be movable between a retracted position in which the drawer-like supporting structure ( 13 ) is recessed into the front wall ( 2 a ) of the casing ( 2 ) and the appliance control panel ( 11 ) is arranged substantially coplanar to the front wall ( 2 a ) of the casing ( 2 ), and a extracted position in which the drawer-like supporting structure ( 13 ) partly juts out from front wall ( 2 a ) of the casing ( 2 ) and the appliance control panel ( 11 ) is forward spaced apart from front wall ( 2 a ) of the casing ( 2 ). The water softening device ( 12 ) being provided with an exposable loading inlet or mouth ( 33 a, 52 ) structured for allowing the user to load the regeneration agent inside the regeneration-agent reservoir ( 29 ), and being at least partly arranged/located on the drawer-like supporting structure ( 13 ) so that said loading inlet or mouth ( 33 a, 52 ) is freely accessible by the user when the drawer-like supporting structure ( 13 ) is arranged in the extracted position.

First claim

The invention claimed is:

1. A laundry washing machine comprising an outer 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 the 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 water softening device 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 the water softening function of the water softening agent stored into the water-softening agent container;
the laundry washing machine further comprising an appliance control panel which is structured for allowing the user to manually select the desired washing-cycle and is located on a front wall of the casing, and
wherein said appliance control panel is located/arranged at a front side of a drawer-like supporting structure which is fitted/inserted in extractable manner into the front wall of the casing, so as to be movable between a retracted position in which the drawer-like supporting structure is recessed into the front wall of the casing, and an extracted position in which the drawer-like supporting structure partly juts out from front wall of the casing and the appliance control panel is forward spaced apart from front wall of the casing; and
wherein the water softening device is provided with an exposable loading inlet or mouth structured for allowing the user to load the regeneration agent inside the regeneration-agent reservoir, and is moreover at least partly arranged/located on the drawer-like supporting structure so that said loading inlet or mouth is freely accessible by the user when the drawer-like supporting structure is arranged in the extracted position;
the detergent dispensing assembly arranged inside the casing and provided with a corresponding exposable loading inlet or mouth located on the front wall of the casing, beside the drawer-like supporting structure carrying the appliance control panel, and structured for allowing the user to load the detergent or other washing agent inside the detergent dispensing assembly.

2. The laundry washing machine according to claim 1 , wherein the washing tub comprises an opening or mouth directly facing a laundry loading/unloading opening realized in the front wall of the casing, and in that the drawer-like supporting structure is fitted/inserted in extractable manner into the front wall of the casing above said laundry loading/unloading opening.

3. The laundry washing machine according to claim 1 , 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.

4. The laundry washing machine according to claim 3 , 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 the outside of the casing via a front entrance or opening provided at the front wall of the casing above the laundry loading/unloading opening and beside the drawer-like supporting structure.

5. The laundry washing machine according to claim 1 , wherein the water softening device further comprises a water supply circuit which is structured for channelling 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.

6. 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 is structured for regulating/controlling the outflow of the brine from the regeneration-agent reservoir to the water-softening agent container.

7. The laundry washing machine according to claim 1 , wherein the regeneration-agent reservoir is at least partly located/incorporated into the drawer-like supporting structure.

8. The laundry washing machine according to claim 7 , wherein the regeneration-agent reservoir is housed into the drawer-like supporting structure in a manually removable manner.

9. The laundry washing machine according to claim 7 , wherein the regeneration-agent reservoir comprises a substantially basin-shaped, regeneration-agent container which is manually fillable with a given quantity of consumable regeneration agent, and is located/incorporated into the drawer-like supporting structure so that the mouth of the basin-shaped container is freely accessible by the user when the drawer-like supporting structure is arranged in the extracted position, and is hidden and inaccessible by the user when the drawer-like supporting structure is arranged in the retracted position.

10. The laundry washing machine according to claim 9 , wherein a water supply circuit of the water softening device is structured for spilling/pouring a shower of the water droplets by gravity into the substantially basin-shaped container of the regeneration-agent reservoir when the drawer-like supporting structure is arranged in the retracted position.

11.
