Abstract:
1. A sink disposal system, comprising (a) a sink; (b) a disposal unit mounted below the sink, the disposal unit comprising a shredding mechanism for shredding waste received from the sink that enters into a shredding area of the disposal unit; (c) a fluid passageway that extends from a drain of the sink downwardly to the disposal unit for passage of waste from the sink to the disposal unit; (d) a control unit operatively connected to the disposal unit and configured to inhibit shredding operation of the disposal unit; and (e) a metal detector sensor and associated circuitry, the metal detector sensor being located adjacent the fluid passageway extending from the drain of the sink to the disposal unit such that the metal detector sensor monitors waste for shredding by the shredding mechanism of the disposal unit as it passes through the fluid passageway extending from the drain of the sink to the disposal unit before it arrives at the disposal unit; (f) wherein the control unit is operatively connected to the disposal unit and to the circuitry associated with the metal detector sensor such that the control unit inhibits shredding operation of the disposal unit upon the detection of metal passing by the metal detector sensor, including,
