Door lock system for an appliance

A door lock system for a domestic appliance, comprising:

• a hook pivotable between an unlocked orientation and a locked orientation about a pivot axis, said hook being linearly translatable along a main axis of the system that is perpendicular to said pivot axis, said hook being biased in said unlocked orientation by a first spring, wherein said hook is adapted to interfere with a counterpart in said locked orientation and to avoid interference with said counterpart in said unlocked orientation in order to reversibly lock and unlock a door of said appliance, respectively;
• a first sliding member movable along the main axis relative to said pivot axis and engageable with said hook such that translation of said first sliding member in a first direction along the main axis toward said pivot axis causes said hook to pivot into said locked orientation against the bias of said first spring, and that translation of said first sliding member in a second direction along the main axis opposite the first direction allows said hook to return to said unlocked orientation in accordance with the bias of said first spring;
• a second sliding member and a third sliding member both slidably engaged with one another and movable along the main axis, said second and third sliding members together being arranged in series with one another and in parallel with respect to the first sliding member;
• and
• a motor coupled with and adapted to rotatably drive a cam relative to a cam axis, said cam comprising first and second eccentric disks, the first eccentric disk engageable with and adapted to drive the first sliding member in said first direction upon actuation of said motor to rotate the cam to at least a first rotational extent about said cam axis, the second eccentric disk engageable with and adapted to drive the second sliding member in said first direction upon actuation of said motor to rotate the cam beyond said first rotational degree toward a second rotational extent about said cam axis;
• wherein actuation of the motor to drive the cam to at least said first rotational degree correspondingly advances the first sliding member in said first direction via engagement with said first eccentric disk, thereby pivoting said hook into said locked orientation;
• and
• wherein further actuation of said motor to drive the cam beyond said first rotational degree toward said second rotational degree correspondingly withdraws the second and third sliding members in said second direction via engagement of said second sliding member with said second eccentric disk, said third sliding member thereby engaging with and drawing said hook, in the locked orientation thereof and together with said first sliding member, also in said second direction, such that said hook physically engages and pulls against said counterpart and thereby draws said door toward the appliance.
