Iron featuring liquid phase garment moisturization via soleplate

1. An iron, comprising:

a water reservoir, configured to hold liquid water;

a heatable soleplate;

at least one water outlet opening;

a water atomization and distribution unit, configured to atomize water from the water reservoir and to distribute the atomized water to the at least one water outlet opening;

at least one sensor, configured to monitor at least one motion dependent variable of the iron, including a direction of movement of the iron relative to a fabric being ironed and to generate a reference signal reflecting said variable; and

a control unit, operatively connected to both the water atomization and distribution unit and the at least one sensor, and configured to control a water outflow rate of the at least one water outlet opening by controlling the operation of the water atomization and distribution unit in dependence of the reference signal generated by the at least one sensor,

characterized in that the control unit is configured to control the water outflow rate of at least one water outlet opening in dependence of a direction of movement of the iron, such that the water outflow rate of said water outlet opening is increased when its associated trailing soleplate length increases as a result of a change in said direction of movement, and/or vice versa.

2. The iron according to claim 1 , wherein the soleplate comprises a plurality of water outlet openings, said water outlet openings being divided into a plurality of groups (A, B, C),

wherein the water atomization and distribution unit is configured to selectively distribute atomized water to each of said groups, and

wherein the control unit is configured to control the water outflow rate for each group independently by controlling the operation of the water atomization and distribution unit in dependence of the reference signal generated by the at least one sensor.

3. The iron according to claim 2 , wherein a principal direction of motion (X) of the iron coincides with a line of symmetry of the soleplate, and

wherein a first group (A) of water atomization openings is provided on a first side of said line of symmetry, while a second group (C) of water atomization openings is provided on a second, opposite side of said symmetry line, and

wherein the water outlet openings of said first and second groups (A,C) are spaced apart from an edge of the soleplate such that a shortest distance from their respective centers to the edge is in the range of 1-30 mm.

4. The iron according to claim 1 , wherein the water atomization and distribution unit is configured to generate a mist of liquid water droplets having an average diameter in the range of 1-50 μm.

5. The iron according to claim 1 , wherein the at least one sensor is configured to additionally monitor at least one of the following motion dependent variables of the iron:

a speed of the iron relative to a fabric being ironed, and

an acceleration of the iron.

6. The iron according to claim 5 , wherein the at least one sensor comprises a contactless motion sensor that is configured to collect motion data without making physical contact with a fabric being ironed.

7. The iron according to claim 6 , wherein the contactless motion sensor is an optoelectronic motion sensor.

8. The iron according to claim 6 , wherein the contactless motion sensor is an accelerometer.

9. The iron according to claim 1 , wherein the control unit is configured to control the water outflow rate of the at least one water outlet opening such that—in use—substantially all water deposited on a patch of fabric being ironed is subsequently evaporated by a trailing soleplate portion associated with said at least one water outlet opening.

10. The iron according to claim 9 , wherein the control unit is configured to control the water outflow rate of at least one water outlet opening in dependence of a direction of movement of the iron, such that said water outlet opening is made to release water only when it is associated with a trailing soleplate length that exceeds a predetermined minimum trailing soleplate length.

11. The iron according to claim 10 , wherein the control unit is configured to control the water outflow rate of at least one water outlet opening in dependence of a speed of the iron, such that the water outflow rate of said water outlet opening is increased when the speed of the iron is increased, and/or vice versa.

12. The iron according to claim 11 , wherein the control unit is configured to control the water outflow rate of at least one water outlet opening in dependence of a speed of the iron, such that said water outlet opening is made to release water only when the speed of the iron exceeds a predetermined minimum speed.

13. The iron according to claim 12 , wherein the at least one sensor further comprises:

a soleplate temperature sensor that is operably connected to the control unit and configured to generate a reference signal comprising information about a temperature of the soleplate, and

wherein the control unit is further configured to control the water outflow rate of at least one water outlet opening in dependence of the reference signal from the soleplate temperature sensor.

14. The iron according to claim 13 , further comprising:

an additive reservoir, configured to hold an additive or additive solution; and

a controllable additive dosing valve, configured to selectively bring the additive and reservoir in fluid communication with the water atomization and distribution unit.
