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.

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.

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.

Soleplate for electric iron

Pressing iron composed of a soleplate fixed to a heating body, wherein the soleplate has a pattern of at least 200 steam outlet holes each having a passage cross section smaller than 4 mm, with spacings of less than 10 mm between hole centers, and wherein the pattern of steam outlet holes is interrupted by an imperforate band having a width greater than 10 mm, which band extends over the pattern.

An accessory mount for an electric toothbrush having a motor which is arranged in a handpiece for driving vibration-generating mechanism. The mount including an elongate protective cover attachable to the handpiece. The vibration-generating mechanism is arrangeable in an interior of the elongate protective cover. A sleeve is fitted onto the protective cover so as to cover the protective cover over at least part of its length.
