Bouleau - Web page: https://patentgrep.com/patent/US5345704A ## 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 comprises a casing (1) whose rear provides a heel (2) and a sole (3) heated by an electric resistance (4), and is adapted to occupy two positions, either an ironing position in which it rests on the sole (3), or a rest position in which it rests on the heel (2). The sole (3) has a partition (5) forming with a closure plate (6) a vaporization chamber (7) which is supplied with water from a reservoir (8) and which, on the one hand, communicates with a steam distribution chamber (9) having outwardly opening steam distribution openings (10), and, on the other hand, comprises a so-called de-scaling opening (11) opening into a rear portion of the iron and closed by a removably mounted closure. The closure is a removable receptacle (12) for recovery of calcified deposit communicating by a weir (13) with a vaporization chamber (7), so that the calcified deposit present in the vaporization chamber (7) falls into the receptacle (12) particularly when the iron occupies its rest position. ## Claims ### Claim 1 In an electric steam iron comprising a casing (1) whose rear provides a heel (2) and a sole (3) heated by an electric resistance (4), said iron being capable of occupying two positions, either an ironing position in which the iron rests on the sole (3), or a rest position in which the iron rests on the heel (2), said sole (3) having a partition (5) forming with a closure plate (6) a vaporization chamber (7) which is supplied with water from a reservoir (8), said vaporization chamber (7) communicating with a steam distribution chamber (9) having outwardly opening steam distribution openings (10) and having a de-scaling opening (11) opening into a rear portion of the iron and closed by removably mounted closure means; the improvement wherein said closure means comprises a removable receptacle (12) for collecting calcified deposit communicating by a weir (13) with said vaporization chamber (7), whereby calcified deposit present in the vaporization chamber (7) falls into the receptacle (12) when the iron occupies said rest position. ### Claim 2 (depends on 1) Iron according to claim 1, wherein the de-scaling opening (11) opens through the closure plate (6), an edge (11') of said opening constituting with the partition (5) of the vaporization chamber (7) said weir (13). ### Claim 3 (depends on 1) Iron according to claim 1, wherein the receptacle (12) and the casing (1) have mutual interlocking means. ### Claim 4 (depends on 1) Iron according to claim 1, wherein the receptacle has a bottom (14) located below the level of the de-scaling opening (11) and the closure means comprises a declivity (15) extending from said de-scaling opening (11) to the bottom (14) of the receptacle (12), so as to oppose, in the ironing position, the return of calcified deposit present in the receptacle (12) toward the vaporization chamber (7). ### Claim 5 (depends on 4) Iron according to claim 4, wherein the closure means comprises a conduit (16) having two ends, one end being sealingly mounted about the de-scaling opening (11) and the other end being provided with a joint (17) sealing with the receptacle (12). ### Claim 6 (depends on 5) Iron according to claim 5, wherein the closure plate (6) is separated from the casing (1) by a heat shield (18) of heat resistant plastic material, and the conduit (16) is formed in one piece with said shield (18) and has an inclined region constituting the declivity (15). ### Claim 7 (depends on 5) Iron according to claim 5, wherein the receptacle (12) and the casing (1) have mutual interlocking means, said interlocking means comprising a rigid abutment (22) integral with the casing (1) and a flexible abutment constituted by the joint (17), such that the receptacle (12) is housed elastically between the casing (1) and the joint (17). ### Claim 8 (depends on 7) Iron according to claim 7, wherein the reservoir (8) is removable and is disposed in a recess (19) provided in a rear portion of the casing (1), the receptacle (12) having a finger (20) projecting into an opening (21) provided in the recess (19) and accessible from said recess, such that the receptacle (12) is disconnectible by pushing on said finger (20). ### Claim 9 (depends on 7) Iron according to claim 7, further comprising an unlocking lug located in a rear portion of the receptacle (12), whereby the receptacle (12) is disconnectible by pushing on said lug. ### Claim 10 (depends on 1) Iron according to claim 1, wherein the receptacle (12) is of thermosetting plastic material.
