  • Patent number: 10385503
    Abstract: An iron includes a soleplate, a heating body including a lower face in thermal contact with the soleplate and an upper face at which a vaporization chamber is provided, and a system for injecting water into the chamber including two injection openings that simultaneously inject water onto two separate evaporation areas of a bottom wall of the chamber when the soleplate is arranged horizontally. The chamber is bordered laterally by a side wall extending from the bottom wall to a closing cover attached to the heating body, the side wall including a passage establishing communication between the chamber and a steam distribution circuit leading to a steam outlet opening provided in the soleplate. The passage is provided at one longitudinal end of the chamber. The chamber includes a separation wall extending from the two evaporation areas to the passage to provide a partition between the two evaporation areas.

  • Patent number: 10358764
    Abstract: Steam iron comprising a heating body (3) comprising a steam chamber (32) and an ironing surface (52) connected thermally to the heating body (3), the ironing surface (52) being designed to come into contact with the fabric to be ironed, and being advantageously provided with steam release holes (50), the heat produced by the heating body (3) being transferred to the ironing surface (52) by conduction through at least two components (3, 4) of the iron, pressed together, characterized in that the two components (3, 4) are in direct contact with one another at at least one point of contact (40A) with a contact surface area of less than 2 mm2 and preferably less than 1 mm2.

  • Patent number: 8522462
    Abstract: Piezoelectric pump for a household electric appliance having a moving wall interposed between a first casing element defining a pumping chamber with the moving wall, and a second casing element applying pressure to the periphery of the moving wall in order to hold the latter in position. The moving wall has an exterior face in contact with a piezoelectric actuator designed to cause the moving wall to move so as to bring about a periodic variation in the volume of the pumping chamber under the action of the piezoelectric actuator wherein the first casing element and the second casing element are held together under stress by an elastic clip, the elastic clip applying a pressure that tends to compress the first casing element onto the second casing element.

  • Patent number: 8484869
    Abstract: Provided is an ironing appliance, including a pump that has a pumping chamber provided with an inlet and an outlet, the pumping chamber including a moveable wall having an outer surface contacting a piezoelectric actuator provided to move the movable wall while changing the volume of the pumping chamber by the piezoelectric actuator, wherein the pump is placed in the ironing appliance such that the outlet of the pumping chamber is located at a higher level than the inlet in a normal position for operating the appliance.
