Abstract: Provided is a hairdressing appliance, which includes a portable treatment unit provided with a gripping device and a heat and steam treatment system configured for heating hair and for applying steam to this hair, a base remote from the portable treatment unit, and connection device between the base and the portable treatment unit configured for supplying the portable treatment unit at least with electricity from the base. The hairdressing appliance includes a circuit board for controlling the treatment system arranged in the base and a system of communication between the control circuit board and the treatment system. The hairdressing appliance enables, for example, the straightening, curling, or crimping of hair and chiefly aims to reduce the weight and the bulk of the portable treatment unit so as to make it easier to handle during styling.

Abstract: Control process for a piezoelectric pump (100) of an electric household appliance comprising a pump chamber (110) equipped with a mobile wall (111) displaceable under the action of a piezoelectric actuator (111A), characterized in that during a startup phase of the pump (100), the piezoelectric actuator (111A) is supplied during a plurality of alternations with an alternating supply signal having a voltage U bringing about a substantial deformation of the piezoelectric actuator (111A) for a maximum sweeping of the volume of the pump chamber (110) by the mobile wall (111), and further characterized in that the pump startup phase is followed by a normal operation phase during which the supply signal is modified so that the mean flow rate provided by the pump (100) is less than the flow rate provided during the startup phase.

Abstract: The invention relates to a circuit (20) for supplying power to a piezoelectric pump (10) from the electric network (25). According to the invention, the circuit (20) supplies power to the pump (10) directly at the frequency of the electric network (25), and said circuit (20) comprises at least means for limiting the current absorbed by the pump (10) arranged in series with said pump (10).
