Kubicz - Web page: https://patentgrep.com/patent/US5704143A ## CPC - D06F 75/18: the water being fed slowly, e.g. drop by drop, from the reservoir to a steam generator - D06F: LAUNDERING, DRYING, IRONING, PRESSING OR FOLDING TEXTILE ARTICLES ## Abstract An electric steam iron, with a soleplate, has a water reservoir which feeds a primary steam generating area and secondary surge steam generating areas. The primary steam generating area feeds steam to a distribution chamber through a first passage, and the surge steam areas feed steam through a second passage which is separate and remote of the first passage. ## Claims ### Claim 1 In an electric steam iron having a soleplate with a heating element, a water reservoir and means for depositing water from the reservoir onto the soleplate at a first location for ordinary steam generation and at least one second location for surge steam generation and a steam distribution chamber for transmitting ordinary steam and surge steam from said soleplate, wherein the improvement comprises: the soleplate having a first primary steam generating area with the first location thereat and at least one substantially separate second surge steam generating area with the at least one second location located thereat, said first primary steam generating area communicating with said steam distribution chamber directly through a first passage and said at least one second surge steam generating area communicating with said steam distribution chamber through a second passage located substantially remotely of and separately from said first passage; said at least one second location being located laterally offset of said heating element; said at least one second surge steam generating area makes up part of a generally U-shaped chamber; and said at least one second location includes two locations each defined by collecting pockets and each disposed on symmetrically opposite sides of said generally U-shaped steam generating area. ### Claim 2 (depends on 1) An iron as defined in claim 1 further characterized in that each of said collecting pockets corresponds to a point laterally inwardly of said heating element. ### Claim 3 (depends on 2) An iron as defined in claim 2 further characterized in that each of said collecting pockets is located laterally outwardly of said heating element. ### Claim 4 (depends on 3) An iron as defined in claim 3 further characterized in that each of said collecting pockets corresponds to a portion of a separating wall disposed in close proximity with the heating element and communicating with water deposited from said reservoir. ### Claim 5 (depends on 4) An iron as defined in claim 4 further characterized in that each of said collecting pockets communicates with said generally U-shaped steam generating area through a necked wall portion. ### Claim 6 (depends on 1) An iron as defined in claim 1 further characterized in that said first passage from said first primary steam generating area to said steam distributing chamber in said iron is located at the rear of the iron and said at least one second surge steam generating area being located directly on said heating element. ### Claim 7 (depends on 6) An iron as defined in claim 6 further characterized in that said second passage from said second steam generating area to said steam distributing chamber in said iron is located at the front of the iron. ### Claim 8 (depends on 1) An iron as defined in claim 1 further characterized in that each of said collecting pockets communicates water deposited from said reservoir through a flow splitter. ### Claim 9 In an electric steam iron having a soleplate with a heating element, a water reservoir and means for depositing water from the reservoir onto the soleplate at a first location for ordinary steam generation and a steam distribution chamber for transmitting ordinary steam and surge steam from said soleplate, and at second locations for surge steam generation, wherein the improvement comprises: the soleplate having a first primary steam generating area with the first location thereat and substantially separate second surge steam generating areas, the second locations located in the second surge steam generating areas and communicating with said steam distribution chamber directly through second passages which proceed from the rear of the iron forwardly thereof, and said first primary steam generating area communicating with said steam distribution chamber at a first passage means located substantially at the rear of the iron and said second surge steam generating area communicating with said steam distribution chamber at the front of said iron through a second passage means disposed remotely of and separately of the first passage means. ### Claim 10 (depends on 9) An iron as defined in claim 9 further characterized in that said second locations being located laterally offset of said heating element. ### Claim 11 (depends on 10) An iron as defined in the claim 10 wherein said second surge steam generating areas define a generally U-shape. ### Claim 12 (depends on 11) An iron as defined in claim 11 further characterized in that said second locations include two collecting pockets each disposed on symmetrically opposite sides of said generally U-shaped steam generating area. ### Claim 13 (depends on 12) An iron as defined in claim 12 further characterized in that each of said collecting pockets corresponds to a point laterally inwardly of said heating element. ### Claim 14 (depends on 12) An iron as defined in claim 12 further characterized in that each of said collecting pockets is located laterally outboard of said heating element. ### Claim 15 (depends on 12) An iron as defined in claim 12 further characterized in that each of said collecting pockets corresponds to a portion of a separating wall disposed in close proximity with the heating element and communicating with water deposited from said reservoir. ### Claim 16 (depends on 15) An iron as defined in claim 15 further characterized in that each of said collecting pockets communicates with said generally U-shaped steam generating area through a necked wall portion. ### Claim 17 (depends on 11) An iron as defined in claim 11 further characterized in that each of said collecting pockets communicates with water deposited from said reservoir through a flow divider.
