Abstract:
1. A food waste disposer system for a sink comprising: a disposer unit having a food conveying section, a motor section and a grind and discharge section, the food conveying section conveying food waste to the grind section of the grind and discharge section; the grind section including a grind mechanism, the grind mechanism including a stationary grind ring and a rotating shredder plate assembly that rotates within the stationary grind ring to grind food waste, the rotating shredder plate rotated by a motor of the motor section; an extension tube from an inlet housing of the food conveying section, the extension tube having an upper end removably securable to a sink flange mounted in the sink and a lower end coupled to the inlet housing of the food conveying section; a switch unit attached to a tubular body of the extension tube and including a first magnet that is movable relative to the tubular body between a first position in which the switch unit is in a first state allowing activation of the motor and a second position in which the switch unit is in a second state preventing activation of the motor; an activation member at least partially receivable within the extension tube for relative rotation therebetween, the activation member including a second magnet positioned such that rotational alignment between the first and second magnets causes the first magnet to move to the first position; a track formed on one of a radially outer surface of the activation member and an inner circumferential portion of the tubular body of the extension tube, the track including a detent; and a protrusion formed on the other of the radially outer surface of the activation member and the inner circumferential portion of the tubular body of the extension tube, the protrusion being adapted to slidably engage the track to facilitate relative rotation between the activation member and the extension tube and be at least partially receivable in the detent to rotationally align the first and second magnets.
