Steam iron
Steam irons are known which provide steam to a fabric of a garment to be pressed through holes in a sole plate. The present invention relates to a steam iron comprising a main body ( 2 ), a steam generating unit ( 6 ) and a sole portion ( 4 ). The sole portion ( 4 ) comprises a steam cavity ( 20 ) and an outer rim ( 19 ) extending around the steam cavity ( 20 ), the outer rim ( 19 ) having a fabric contact surface ( 22 ) and the steam cavity ( 20 ) having a permeable element ( 42 ) disposed therein. Therefore, steam supplied into the steam cavity ( 20 ) from the steam generating unit ( 6 ) is supplied to a fabric to be pressed when the fabric contact surface ( 22 ) is located against said fabric.
1. A steam iron comprising a main body, a steam generating unit and a sole portion, the sole portion including a steam cavity adapted for communication with the steam generating unit and a heatable area comprising a tip portion and a peripheral rim portion that together extend around and define a boundary of the steam cavity, the heatable area forming a fabric contact surface for pressing the fabric and the steam cavity having a resiliently deformable, steam permeable material disposed therein for forming a fabric contact surface through which steam supplied the steam cavity from the steam generating unit is distributed to the fabric to be pressed during operation.
2. A steam iron according to claim 1 where the resiliently deformable, steam permeable material is depressed into the steam cavity during contact with fabric to be pressed.
3. A steam iron according to claim 1 where the resiliently deformable, steam permeable material has an outer surface portion arranged for facing the fabric to be pressed and is disposed on a support panel of the sole portion.
4. A steam iron according to claim 3 where the support panel defines a steam distribution chamber.
5. A steam iron according to claim 3 where the resiliently deformable, steam permeable material is fixedly mounted to support panel.
6. A steam iron according to claim 3 where the support panel comprises a mesh material.
7. A steam iron according to claim 1 where the resiliently deformable, steam permeable material comprises an inner resiliently deformable portion and an outer surface layer forming the second fabric contact surface.
8. A steam iron according to claim 1 comprising a steam distribution chamber located adjacent an inner side of the steam permeable element such that steam from the steam generating unit flows into the steam distribution chamber and flows through the steam permeable element to an outer surface of the steam permeable element.
9. A steam iron according to claim 1 where the steam permeable element comprises a first portion and a second portion.
10. A steam iron according to claim 1 where the tip portion comprises a heatable tip element configured to contact the fabric to be pressed.
11. A steam iron according to claim 10 where the heatable tip element is integrally formed with a heat conducting member in thermal contact with the steam generating unit.
12. A steam iron according to claim 1 comprising a base unit, said steam generating unit being disposed in the base unit and being adapted for coupling to the main body through a pipe.
13. A steam iron according to claim 1 comprising a heater element and a heat insulation member disposed between the heater element and the steam permeable element.
14. A steam iron comprising a main body, a steam generating unit and a sole portion, the sole portion defining a steam cavity adapted for communication with the steam generating unit and including a heatable outer area extending around the steam cavity, the heatable outer area having a first fabric contact surface for pressing the fabric and the steam cavity having an element of steam permeable material disposed therein such that steam supplied into the steam cavity from the steam generating unit passes thought the steam permeable element and is supplied to the fabric to be pressed, said steam permeable element having an outer surface for facing the fabric and defining a base of the steam cavity, said outer surface being depressed relative to the first fabric contact surface such that said base does not contact a fabric to be pressed when the first fabric contact surface is positioned against said fabric.
15. A steam iron comprising a main body, a steam generating unit and a sole portion, the sole portion defining a steam cavity adapted for communication with the steam generating unit and including a heatable outer area extending around the steam cavity, the heatable outer area having a first fabric contact surface for pressing the fabric and the steam cavity having an element of steam permeable material disposed therein such that steam supplied into the steam cavity from the steam generating unit passes through the steam permeable element and is supplied to the fabric to be pressed;
said steam permeable element comprising a first portion and a second portion and said steam cavity comprising a first section and a second section, the first portion of the steam permeable element being disposed in the first section of the steam cavity and the second portion of the steam permeable element being disposed in the second section of the steam cavity so that said first and second portions of the steam permeable element can be separately supplied with fluids of different types, including air, steam, mist and combinations thereof.
16. A steam iron according to claim 15 where the first portion of the steam permeable element comprises one of a different material and a different structure than the second portion of the steam permeable element.
