  • Patent number: 6807756
    Abstract: The invention relates to an iron (1) comprising a container of water (2) at atmospheric pressure. The water from the container flows through a nozzle between said container (2) and a heated and regulated steam chamber (5). An iron sole plate (3) forms the ironing surface and steam outlet holes (12) are arranged in said sole plate (3). The invention is characterized in that the iron (1) comprises means for creating a resonance or relaxation vibration in the water and steam circuit. The cyclic variation in the steam pressure is automatically maintained at an average pressure above that corresponding to the column of water available in the iron.

  • Patent number: 6802141
    Abstract: The second vapor circuit of the second vaporizing chamber has, along the heating element (201), and located at the top of the heating body, a top channel (222) directed from the chamber towards the rear of the sole plate, and connected to the bottom channel (223) going from the rear towards the point of the sole plate, situated under the heating body of the sole plate. The iron has a heating unit (2) with a heater element, this heating unit also having a first vaporizing chamber (210) used for normal ironing, and a second independent vaporizing chamber (220) used for obtaining a surplus of vapor, each of these chambers having a vapor circuit ending in a set of vapor orifices in the sole plate.

  • Patent number: 6763620
    Abstract: The invention relates to a steam iron with instantaneous vaporization comprising a water container (2), a steam chamber (32), an anti-drip device (80) and a drip device having a rod (4) which moves axially. According to the invention, the total stroke of the axially-moving rod (4) comprises a first stroke which provides the flow of water through the opening (520) of a module (5) that receives the water from the container (2) via the anti-drip device (80) and a second stroke which simultaneously opens a direct passage for the water to flow from the container (2) to the module (5) and moves the module (5) by opening a larger hole for the water to flow from the container to the steam chamber.

  • Patent number: 6725586
    Abstract: The invention concerns a flash iron comprising a water reservoir (2), a flash chamber (32) and a drip device having an axially mobile rod (4) whereof the total stroke comprises a first travel enabling the steam to flow towards the orifice (520) of a module (5) and a second travel moving the module (5) by opening a wider orifice (220) for water passing from the reservoir (2) to the flash chamber (32). The invention is characterised in that the tightness between the reservoir (2), the module (5) and the flash chamber (32) is provided by a first compressed seal, and the tightness between the rod and the module is provided by a second compressed seal, the two seals being parts of one and the same elastomeric component (52) borne by the module (5).
