Abstract

The present application relates to a steam iron head ( 30 ). The steam iron head ( 30 ) has a steam pathway ( 40 ) along which steam flows. A cyclonic chamber ( 61 ) is along the steam pathway ( 40 ). The steam iron head ( 30 ) also has a flow inlet ( 62 ) to the cyclonic chamber ( 61 ), a flow outlet ( 63 ) from the cyclonic chamber ( 61 ), and a conduit ( 67 ) in the cyclonic chamber ( 61 ) defining the flow outlet ( 63 ). The conduit ( 67 ) upstands in the cyclonic chamber ( 61 ) and has an opening in a free end ( 68 ) of the conduit through which the flow of steam exits the cyclonic chamber ( 61 ). The conduit ( 67 ) is provided with a rib ( 91 ) to restrict the flow of water droplets formed on an outer surface of the conduit from passing through the flow outlet ( 63 ). The present application also relates to a steam system iron ( 10 ) having a steam iron head ( 30 ).

First claim

The invention claimed is:

1. A steam iron head comprising:
a steam pathway for the passage of a flow of steam,
a cyclonic chamber defining a helical flow path of the flow of steam along the steam pathway between a flow inlet of the cyclonic chamber and a flow outlet of the cyclonic chamber,
a conduit upstanding in the cyclonic chamber,
an opening at a free end of the conduit, the opening forming the flow outlet through which the flow of steam exits the cyclonic chamber, and
a barrier on an outer surface of the conduit, wherein the barrier includes a rib extending circumferentially around the conduit and protruding from the outer surface at the free end of the conduit.

2. The steam iron head according to claim 1 , wherein the rib is a lip extending circumferentially around the conduit.

3. The steam iron head according to claim 1 , wherein a lower side of the rib extends substantially perpendicular to a longitudinal axis of the conduit.

4. The steam iron head according to claim 1 , wherein a lower side of the rib extends at an acute angle to the longitudinal axis of the conduit.

5. The steam iron head according to claim 2 , wherein the barrier further includes at least one groove formed in the outer surface of the conduit.

6. The steam iron head according to claim 1 , wherein the barrier is annular-shaped.

7. The steam iron head according to claim 2 , wherein a gap is provided between the outer periphery of the rib and the peripheral sidewall of the cyclonic chamber, the gap being equal to or greater than the flow area of the flow outlet.

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