Abstract

A laundry washing machine comprising: a cabinet, a washing tub housed inside the cabinet, a tubular mantle rotatably housed inside the cabinet, an electric additive treating device mounted in/on the tubular mantle and configured for treating a washing and/or rinsing additive loaded within the tubular mantle in such a way to generate within the tubular mantle a solution of washing and/or rinsing additive water.

Claims (30)

1 . A laundry treating appliance comprising:

a cabinet;

a tubular mantle housed inside the cabinet and rotatable with respect to a rotation axis, the tubular mantle comprising a first end and an inner volume configured to receive laundry;

a flange fixed to and rotatable with the tubular mantle, wherein the first end of the tubular mantle is at least partially closed by the flange;

a liquid reservoir fixed to the tubular mantle or to the flange and defining an interior space configured to contain a liquid;

an electric liquid treating device fixed to the tubular mantle or to the flange, and fluidly connected with the liquid reservoir and configured to receive and treat the liquid to thereby release, within the tubular mantle, at least one of a vapor, a mist, or an aerosol; and

a power source configured to supply electric power to the electric liquid treating device from a non-rotating part of the laundry treating appliance, wherein the power source is selected from a group consisting of a sliding electric contact system and a wireless power transmitter unit, and wherein the wireless power transmitter unit is configured to wirelessly transmit electric power to a wireless power receiver unit rotating with the tubular mantle.

2 . The laundry treating appliance according claim 1 , wherein the tubular mantle comprises a lifter protruding into the inner volume and having a hollow body, and the liquid reservoir and the electric liquid treating device are mounted on or at least partially inside the hollow body.

3 . The laundry treating appliance according to claim 1 , wherein the electric liquid treating device comprises one or more pumps fluidly connected to the liquid reservoir and configured for drawing the liquid from the liquid reservoir and pumping it in a different region.

4 . The laundry treating appliance according to claim 3 , wherein at least one pump of the one or more pumps is configured for pumping the liquid through a nebulizing nozzle fixed to the tubular mantle or to the flange to thereby inject mist within the tubular mantle.

5 . The laundry treating appliance according to claim 3 , wherein at least one pump of the one or more pumps is configured for pumping the liquid to a liquid container fixed to the tubular mantle or to the flange.

6 . The laundry treating appliance according to claim 5 , wherein the electric liquid treating device further comprises an electric heater positioned within the liquid container and configured for heating the liquid contained therein until producing vapor.

7 . The laundry treating appliance according to claim 6 , wherein the electric liquid treating device further comprises a temperature sensor configured to sense a temperature of the liquid in the liquid container, and a control unit configured to control the electric heater depending on the temperature.

8 . The laundry treating appliance according to claim 5 , wherein the electric liquid treating device further comprises a vibrating membrane positioned within the liquid container and configured for producing mist by vibrating the liquid contained in the liquid container.

9 . The laundry treating appliance according to claim 5 , wherein the electric liquid treating device further comprises an aerosol generating device configured for pumping air into the liquid container to generate an aerosol.

10 . The laundry treating appliance according to claim 5 , wherein the liquid container comprises one or more apertures and/or perforated surfaces through which vapor and/or mist and/or aerosol contained within the liquid container can exit the liquid container.

11 . The laundry treating appliance according to claim 3 , wherein at least one of the one or more pumps is configured for pumping the liquid to a three-way valve configured for selectively directing the liquid to a nebulizing nozzle configured for injecting mist within said tubular mantle, and/or to a liquid container fixed to the tubular mantle or to the flange.

12 . The laundry treating appliance according to claim 1 , wherein the electric liquid treating device comprises an electric heating device configured for heating the liquid until producing vapor.

13 . The laundry treating appliance according to claim 1 , wherein the electric liquid treating device comprises a vibrating membrane to vibrate the liquid to produce a mist.

14 . The laundry treating appliance according to claim 13 , wherein the vibrating membrane is configured to vibrate at an ultrasonic frequency.

15 . The laundry treating appliance according to claim 1 , wherein the electric liquid treating device comprises an aerosol generating device configured for pumping air into said liquid to generate an aerosol.

16 . The laundry treating appliance according to claim 1 , further comprising a conditioning device fixed to the tubular mantle or to the flange, wherein the conditioning device is configured to add a conditioning substance to the liquid before the liquid is turned into mist and/or vapor and/or aerosol.

17 . The laundry treating appliance according to claim 16 , wherein the conditioning device comprises a conditioning substance reservoir configured for receiving a conditioning substance and crossed by a conduit in which the liquid flows before being turned into mist and/or vapor and/or aerosol, in such a way that the liquid mixes with the conditioning substance before being turned into mist and/or vapor and/or aerosol.

18 . The laundry treating appliance according to claim 1 , further comprising a light generating source fixed to the tubular mantle or to the flange and configured for emitting light within the tubular mantle.

19 . The laundry treating appliance according to claim 18 , wherein the light generating source is configured to generate ultraviolet light or to generate light at more than one frequency.

20 . The laundry treating appliance according to claim 19 , wherein the light generating source is housed at least partially within a hollow lifter protruding into the inner volume of the tubular mantle, and wherein the lifter comprises a window that is transparent to the light emitted by the light generating source.

21 . The laundry treating appliance according to claim 1 , wherein the laundry treating appliance comprises a control unit configured for managing one or more operations of the laundry treating appliance, and wherein the electric liquid treating device is controlled by the control unit.

22 . The laundry treating appliance according to claim 1 , wherein:

the tubular mantle comprises one or more outlets fixed for rotating together with the tubular mantle, the one or more outlets being configured to pass the at least one of the vapor, the mist or the aerosol to the within the tubular mantle;

wherein the laundry treating appliance comprises a sensor system configured for detecting a data related to the position of at least one of the one or more outlets with respect to a horizontal surface on which the laundry treating appliance is configured to lay.
