Sink disposal and metal sensor

摘要

An apparatus includes: a disposal unit; a control unit configured to stop operation of the disposal unit; and a metal detector coil and associated circuitry, the metal detector coil located such that waste passing into the disposal unit for shredding passes through the metal detector coil. The control unit is triggered to stop operation of the disposal unit upon the detection of metal passing through the metal detector coil.

主权项

1. An under-sink disposal system, comprising
(a) a sink; (b) a disposal located under the sink and comprising a shredding mechanism for shredding waste received from the sink that enters into a shredding area of the disposal; (c) a fluid passageway extending downwardly from a drain of the sink for passing of waste to the shredding area of the disposal; (d) a switch assembly operatively connected to the disposal and configured to inhibit shredding operation of the disposal; and (e) a metal sensor and associated circuitry, the metal sensor being located adjacent the fluid passageway such that a metallic object passing through the fluid passageway toward the shredding area of the disposal is detected by the metal sensor; (f) wherein the switch assembly is operatively connected to the circuitry associated with the metal sensor such that the switch assembly inhibits shredding operation of the disposal upon the detection of a metallic object passing through the fluid passageway toward the shredding area of the disposal, including,
(i) stopping shredding operation of the disposal when running upon the detection of a metallic object passing through the fluid passageway toward the shredding area of the disposal, and(ii) preventing shredding operation of the disposal from starting after the detection of a metallic object passing through the fluid passageway toward the shredding area of the disposal.
