  • Patent number: 8528240
    Abstract: A steam iron having a bipartite steam rate control, based on a combination of a user-control, which allows a user to consciously set a desired steam rate, and an intuitively operated handle, which may conditionally provide the steam rate control assembly with corrective, energy saving input.

  • Patent number: 8522463
    Abstract: An ironing device includes a base, a handle moveable relative to the base, and a resilient member biasing the handle in an upper position and allowing movement of the handle upon exertion of a force thereon by a user towards a lower position. Further, a steam controller is operatively connected to the handle such that release of steam of the ironing device is intuitively controlled by the force exerted on the handle by the user. A console is connected with the base and is provided with at least one operating button. The handle includes a recess for accommodating the console, where the console and the handle are configured so that an operating button is operable with the same hand that holds the handle.

  • Patent number: 8443532
    Abstract: Steam irons with a steam valve that is controlled by an intuitively operated, usually pivotable handle may not provide consistent steam ironing behavior due to the fact that the force exerted on the handle by the user may change over time. To overcome or mitigate the problem, the present invention provides a steam iron (1), comprising a by-pass (9) around the handle-operated valve (7). The by-pass allows a relatively small but continuous water stream to be transported from a water reservoir (6) to steam outlet openings (12) in the soleplate (11) of the iron. Consequently, subject to an ample supply of water, the steam iron provides a minimum of steam ironing comfort throughout a steam ironing session.

  • Publication number: 20110271566
    Abstract: The invention relates to ironing devices that have an intuitive steam emitting feature while the controlling of other functionalities of the ironing device remains possible. The proposed ironing device (1) comprises: a base (2); a handle (3) moveable relative to the base (2); a resilient member (9) biasing the handle in an upper position and allowing movement of the handle upon exertion of a force thereon by a user towards a lower position; a steam controller (4) operatively connected to the handle (3) such that the release of steam of the ironing device (1) at least in part is intuitively controlled by the force exerted on the handle (3) by the user; a console (6) that is connected with the base (2) and that is provided with at least one operating button (7); and at least one recess (5) in the handle at least partly accommodating the console (6), the console (6) and the handle (3) being configured so that the at least one operating button (7) is operable with the same hand that holds the handle (3).
