  • Patent number: 7963469
    Abstract: A food waste disposer having a fluid recycling device includes a plate disposed for rotation within the food waste disposer. At least one fluid recovery member connects a first side of the plate defining a food grinding cavity to a second side of the plate defining a waste receiving cavity. Rotating the plate forces a portion of a waste water/slurry in the waste receiving cavity to back-flow into the food grinding cavity, to recycle/reuse the water. The fluid recovery member can include a fluid passageway oriented at an angle with respect to the plate. A control device can also be used to recycle the portion of the food waste water/slurry.

  • Patent number: 7584915
    Abstract: A food waste disposer includes a housing defining an inlet opening and a grinding mechanism driven by a motor for grinding food waste received into the housing through the inlet opening. An annular retaining collar has one end for connecting to a sink opening, via a standard sink mount, for example. An annular elastomeric coupler is situated about the opposite end of the annular retaining collar and connected to the housing for vibrationally isolating the annular retaining collar from the housing. The primary loading on the elastomeric material is in shear. Elastomeric materials in shear are particularly effective in absorbing both vibration and shock loads.

  • Patent number: 7533835
    Abstract: A food waste disposer system includes a grinding mechanism. The grinding mechanism includes a stationary grind ring and a rotatable shredder plate assembly. A detector is connected to the grinding mechanism to detect the presence of a foreign electrically conductive object in the grinding mechanism. In an aspect, the detector detects that a foreign electrically conductive object is in the grinding mechanism upon sensing that an electrical circuit has been completed between the stationary grind ring and the rotatable shredder plate.

  • Publication number: 20080301871
    Abstract: A food waste disposer mounting assembly uses a stainless steel sink-flange with a screw-on collar system as a primary mounting system to a sink. By connecting the stainless steel sink-flange with a bayonet locking reed collar and screw-on nut collar, a vibration and sound transmission path to the sink is both reduced and rendered indirect. Incorporation of reed switches with a stopper and magnets can modify the unit for use as a batch-feed disposer.

  • Patent number: 7360729
    Abstract: A shredder assembly for a food waste disposer that includes an impact mechanism for freeing jams. The impact mechanism uses the stored energy in the rotating portion of the disposer's rotating elements to be transmitted from the rotor shaft via an impact member to a part of the rotating shredder assembly. The shredder assembly includes a rotatable shaft and an impact member fixedly attached to the shaft to rotate therewith. A shredder disk is attached to the shaft via a clutch allowing the shredder disk to slip relative to the shaft when the shredder disk jams, wherein the impact member strikes the shredder disk to transfer rotational energy to the jam.
