Abstract
A waste disposal device includes a receptacle for holding liquid and waste materials, a liquid drainline secured to the receptacle, a collecting tank connected in the drainline to collect the liquid and waste materials from the receptacle, a waste disintegrator extending into the collecting tank, drive means for operating the waste disintegrator, and control means in the drainline for actuating the drive means upon collection of liquid over a given level in the collecting tank and upon the flow of the liquid out of the tank through the drainline. The waste disintegrator is a rotatable impact knife, the drive means is a motor coupled to the knife, and the control means includes a siphon tube directing the flow of the liquid over a given level out of the tank, and pressure sensitive switching means for sensing a change in pressure in the siphon tube upon the occurrence of the flow of liquid to actuate the motor.
