Actuator mechanism for an item of household equipment

An equipment item for a household, the equipment item comprising:

• a movable component;
• and
• an actuator mechanism configured for driving the movable component, wherein the actuator mechanism comprises:
• an electric motor;
• a coupling part coupled with the movable component in a detachable manner and which is capable of being driven by the electric motor within a limited range of movement for push and/or pull transmitting coupling with the movable component;
• and
• a power transmission mechanism comprising a plurality of gear pairings between the electric motor and the coupling part, wherein the plurality of gear pairings are arranged in parallel power transmission branches, each gear pairing defining a different transmission ratio, and each gear pairing intermeshing engagement in a different section of the range of movement of the coupling part,
• wherein a toothing of each gear pairing is formed as a gear toothing by a circumferential toothing of a gear wheel extending all around and having a different pitch circle diameter in each case, wherein the power transmission mechanism being capable of causing a respectively different effective velocity of the coupling part at a given rotational frequency of the electric motor in different sections of the range of movement of the coupling part and the actuator mechanism being configured to overcome an initial resistance and a closing resistance.

An actuator mechanism for driving a movable component of an item of household equipment, comprising:

• an electric motor;
• a coupling part configured to be driven by the electric motor within a limited linear range of movement for pushing and/or pulling the movable component;
• and
• a power transmission mechanism comprising a plurality of gear pairings between the electric motor and the coupling part, wherein the plurality of gear pairings are arranged in parallel power transmission branches, each gear pairing defining a different transmission ratio, and each gear pairing intermeshing engagement in a different section of the range of movement of the coupling part,
• wherein a toothing of each gear pairing is formed as a gear toothing by a circumferential toothing of a gear wheel extending around the entire circumference of the gear wheel, the power transmission mechanism being capable of ensuring a variable effective velocity of the coupling part at a given rotational frequency of the electric motor, the power transmission mechanism being capable of causing a respectively different effective velocity of the coupling part at a given rotational frequency of the electric motor in different sections of the range of movement of the coupling part and the actuator mechanism being configured to overcome an initial resistance and a closing resistance.
