Abstract

Methods and systems for cooling a soleplate of an iron are disclosed. A method may include flowing a cooling fluid adjacent at least a portion of the soleplate and transferring heat energy from the soleplate to the cooling fluid.

Claims

1. A method for cooling a soleplate of an iron, the method comprising:

flowing a cooling fluid adjacent at least a portion of the soleplate, wherein the soleplate comprises polyimide;

transferring heat energy from the soleplate to the cooling fluid; and

cooling the soleplate from a temperature of greater than 100°

C. to less than 60°

C. in less than 4.5 minutes.

2. A method according to claim 1, where in the flowing comprises drawing cooling fluid into a skirt chamber, wherein the skirt chamber is defined at least in part by the soleplate.

3. A method according to claim 1, wherein the flowing comprises impinging the soleplate with positively pressurized cooling fluid.

4. A method according to claim 1, wherein the cooling fluid comprises ambient air.

5. A method according to claim 1, further comprising:

energizing a heater element associated with the soleplate, wherein heat energy is transferred from the heater element to the soleplate; and

heating the soleplate from room temperature to a temperature of greater than 100°

C. in less than 45 seconds.

6. A method according to claim 1, further comprising turbulating the cooling fluid as it is flowed adjacent the soleplate.

7. A method according to claim 1, further comprising controlling the flowing so that the flowing begins after a heater element in the iron has turned OFF.

8. A method according to claim 1, wherein the flowing a cooling fluid comprises pumping a cooling fluid.

9. A method according to claim 8, further comprising powering the pumping with a capacitor.

10. A method according to claim 8, further comprising powering the pumping with a battery.

11. A device for removing wrinkles from fabric, the device comprising:

a soleplate, wherein the soleplate comprises polyimide;

a heater element associated with the soleplate so as to heat the soleplate; and

a housing of the soleplate and heater element connected to one of the soleplate and heater element, wherein the housing comprises a cooling fluid vent, wherein a cooling fluid is passable through the cooling fluid vent so that heat energy is transferred from one of the soleplate and the heater element to the cooling fluid, wherein the soleplate comprises a thickness less than 2.0 mm.

12. A device as claimed in claim 11, further comprising a fan associated with the soleplate so as to pump a cooling fluid adjacent at least a portion of the soleplate.

13. A device according to claim 12, further comprising a capacitor in electrical communication with the fan.

14. A device according to claim 12, further comprising a battery in electrical communication with the fan.

15. A device according to claim 12, further comprising a controller that turns the fan ON after the heater element has turned OFF.

16. A device according to claim 12, further comprising a controller that turns the fan OFF after the soleplate has cooled to a temperature less than 60°

C.

17. A device according to claim 11, wherein the soleplate comprises:

a first film;

a heating element attached to the first insulating film by a first adhesive layer;

a second film attached to the heating element by a second adhesive layer; and

an ironing plate attached to the second insulating film by a third adhesive layer.

18. A device for removing wrinkles from fabric, the device comprising:

a soleplate comprising a thickness less than 2.0 mm, wherein the soleplate comprises polyimide;

a heater element associated with the soleplate so as to heat the soleplate;

at least one turbulator associated with the soleplate, at least one turbulator comprises a geometric form selected from a group consisting of a bump, a pyramid and a cuboid;

a fan associated with the soleplate so as to pump a cooling fluid in heat-transfer communication with at least a portion of the soleplate, whereby heat energy is transferred from the soleplate to the cooling fluid; and

a controller in signal communication with the fan.

19. A device according to claim 18, wherein the controller turns the fan ON after the heater element has turned OFF, and wherein the controller turns the fan OFF after the soleplate has cooled to a temperature less than 60°

C.

20. A device according to claim 18, wherein the soleplate comprises:

a first film;

a heating element attached to the first insulating film by a first adhesive layer;

a second film attached to the heating element by a second adhesive layer; and

an ironing plate attached to the second insulating film by a third adhesive layer.
