Abstract

A steam iron head (2) employs a soleplate (6) having a fabric contact surface (10), a steam inlet (21) through which steam flows to the steam iron head (2), and one or more steam vents (49). A steam passageway (19) is between the steam inlet (21) and the steam vent(s) (49). A fluid separator (25) is located between the steam passageway (19) and the steam vents (49). The fluid separator (25) is configured to restrict the flow of condensation formed in the steam passageway (19) from passing through the steam vent(s) (49). A soleplate panel (7) forms the fabric contact surface (10) and a base (15, 20) of the steam passageway (19). The soleplate panel (7) is configured to be primarily heated by steam flowing along the steam passageway (19) to the steam vent(s) (49). A steam generator system iron may employ the steam iron head (2).

First claim

The invention claimed is:

1. A steam iron head, comprising:
a soleplate having a fabric contact surface,
a steam inlet through which steam flows to the steam iron head,
at least one steam vent,
a steam passageway between the steam inlet and the at least one steam vent, and
a fluid separator between the steam passageway and the at least one steam vent configured to restrict the flow of condensation formed in the steam passageway from passing through the at least one steam vent,
wherein the soleplate has a soleplate panel forming the fabric contact surface and a base of the steam passageway, and
wherein the soleplate panel is configured to be primarily heated by steam flowing along the steam passageway to the at least one steam vent.

2. The steam iron head according to claim 1 , wherein the temperature of the soleplate panel is configured to decrease when steam is not flowing along the steam passageway.

3. The steam iron head according to claim 1 , wherein the area of the base of the steam passageway is at least 70% of the area of the fabric contact surface.

4. The steam iron head according to claim 1 , wherein the steam passageway has a labyrinth configuration.

5. The steam iron head according to claim 1 , wherein the steam passageway is defined by at least one wall upstanding from the soleplate panel.

6. The steam iron head according to claim 1 , wherein the thickness of the soleplate panel between the base of the steam passageway and the fabric contact surface is less than 2 mm.

7. The steam iron head according to claim 1 , wherein the fluid separator includes a cyclonic chamber between the steam passageway and the at least one steam vent configured to restrict the flow of condensation formed in the steam passageway from passing through the at least one steam vent.

8. The steam iron head according to claim 1 , further comprising a liquid removal arrangement configured to remove liquid separated from steam by the fluid separator.

9. The steam iron head according to claim 8 , wherein the liquid removal arrangement includes a return path to a liquid reservoir.

10. The steam iron head according to claim 9 , wherein the liquid removal arrangement comprises a heater to evaporate liquid separated from steam by the fluid separator.

11. A steam generator system iron comprising the steam iron head according to claim 1 .

12. The steam generator system iron according to claim 11 further comprising a steam valve configured to control the flow of steam through the steam passageway.

13. The steam generator system iron according to claim 12 , wherein the steam iron head further comprises a user input connected to the steam valve configured to control the flow of steam through the steam valve.
