A retractable ventilation system for a household appliance includes a lifting motor for moving the ventilation system in two opposing directions, and a switch controlling movement of the lifting motor. A first actuation of the switch moves the ventilation system in a first (or preferred) of the two directions, and a second actuation of the switch moves the ventilation system in a second direction opposing the first direction. Furthermore, a household appliance includes an extractor hood, a cooking appliance or a combination thereof, and at least one of the proposed retractable ventilation systems. A method for operating the retractable ventilation system is also described.

Retractable ventilation system

A household appliance which includes an activation unit, a power supply unit, a switch that is operated by the activation unit, and a capacitor that is connected in parallel to the switch on the primary side of the power supply unit. The power supply unit is connected to a power supply network and supplies, on the secondary side of the power supply unit, power to controlled functional units of the household appliance and to the activation unit. The switch is operated by the activation unit to disconnect the power supply unit from the power supply network on the primary side of the power supply unit and in an idle state of the household appliance.

Electrical appliance

A household appliance including a wiring, a power supply unit, a switch actuated by the wiring, and an energy store. The power supply unit is connected to a power supply network and supplies power to controlled functional units of the household appliance and to the wiring. The switch, which is actuated by the wiring, disconnects the power supply unit from the power supply network on a primary side of the power supply unit and in an idle state of the household appliance. The energy store stores energy that keeps the switch open in the idle state of the household appliance.
