  • Patent number: 8347531
    Abstract: Steam wrinkle-removing appliance comprising a water tank (110) in direct communication with a steam-producing boiling chamber (60), said boiling chamber (60) comprising a heating unit (4) and a steam outlet (62) through which the steam can freely flow toward a wrinkle-removing element such as a steam brush, characterized in that the boiling chamber (60) is supplied with water from the tank (110) by means of several supply lines (70) with a small flow cross-section of less than 15 mm2, said supply lines extending lengthwise between an end (70A) opening into the tank (110) and an end (70B) opening into the boiling chamber (60) so as to generate head losses that limit the backflow of hot water or steam toward the tank (110).

  • Patent number: 8302334
    Abstract: Steam wrinkle-removing appliance comprising a steam-producing boiling chamber (60) incorporated into a water tank (110), said boiling chamber (60) being in direct communication with the water tank (110) while being supplied with water by gravity via at least one supply line (70) extending from the tank (110), said boiling chamber (60) comprising a heating unit (4) and a steam outlet (62) through which the steam can freely flow toward a wrinkle-removing element (3) such as a steam brush, the tank (110) comprising a filling inlet (121A) in the upper part of the tank (110), characterized in that said steam outlet (62) is in direct communication with a hose (2) connected to the steaming element (3) so that the steam produced by the boiling chamber (60) is not diffused into the tank (110).

  • Patent number: 7181874
    Abstract: The invention concerns a steam iron comprising a water reservoir (1), a hydraulic circuit (3) connecting the reservoir (1) to an electrically heated vaporization chamber (23), the circuit including in series an anti-drip valve (4), and an adjustable drip element (5) capable, in a self-cleaning position, of opening allowing a free passageway and supplying water to said chamber. The invention is characterized in that the drip element comprises means for opening or maintaining open the anti-drip valve (4), when it is in the self-cleaning position.
