STEAM IRON WITH INCREASED WATER HEAD
FIG3b shows a schematic side view of the garment steaming device comprising the steam iron shown in FIG3a in its non-operational orientation
Referring to FIG3b, it can be seen that the steam iron 35 is placed on its heel portion 4 during its non-operational orientation B. FIG3b also illustrates that the soleplate 36 extends at an angle to the horizontal when placed on its heel portion 4 in its non-operational orientation B.

['1. A steam iron (1) comprising: - a first water chamber (2); - a second water chamber (3) situated in a heel portion (4) of the steam iron (1); - a steam generator (5) situated below the first water chamber (2) in an operational orientation (A) of the steam iron (1); - a first fluid path (6) connecting the first water chamber (2) and the steam generator (5); and - a vent pipe (10) connected to a top part of the second water chamber (3) by its first end (11) and open to the atmosphere at its second end (12), the second end (12) of the vent pipe (10) extending at least as far as the maximum water level height of the first water chamber (2) when the steam iron (1) is in a non-operational orientation (B); -  characterized in that  a second fluid path (7) connects a bottom end of the first water chamber (2) to a lower part of the second water chamber (3) in the operational orientation (A), the cross-sectional diameter of the second fluid path (7) is in the range of 2 mm to 15 mm, and the second water chamber (3) is arranged wholly above the first water chamber (2) in the operational orientation (A), so that so long as there is water in the second water chamber (3) a water level height of the second water chamber (3) is higher than a water level height of the first water chamber (2) in said operational orientation (A), so that the water head in the first fluid path (6) generated by the fluid coupling the second water chamber (3) and the first water chamber (2) is increased to obtain an increased steam rate when the steam iron (1) is in the operational orientation (A).', '9. The steam iron (1) according to any preceding claim, wherein the first water chamber (2) comprises a water inlet (29) and a sealing member (30) located on a sidewall thereof, the water inlet (29) being configured to allow the first water chamber (2) and the second water chamber (3) to be filled with water in the non-operational orientation (B), the sealing member (30) being configured to seal the water inlet (29) once the first water chamber (2) and second water chamber (3) have been filled and prior to the movement of the steam iron (1) into the operational orientation (A).', '12. The steam iron (1) according to any preceding claim, wherein the vent pipe (10) is arranged inside a handle (41) of the steam iron (35).', '13. The steam iron (1) according to any preceding claim, wherein there is a soleplate (36) situated against the steam generator (5) in which water is converted into steam, the soleplate (36) having multiple steam venting holes (38) thereon and facing the garment to be ironed once the garment steaming device (1) is moved into the operation orientation (A) from the non-operational orientation (B).']
