  • Chokeless Sink Strainer
    Publication number: 20080307573
    Abstract: The invention resolves the choking problem of the existing sink strainers. The new design has a water outlet and a residues settlement area. See FIG. 7 for the concept design. The water outlet is designed at above the surface of the sink and the settlement area is at below the surface. The residues will eventually settle down in the settlement area when the water flows through the strainer. The water outlet will not be covered by the residues as it is above the surface. Having these two features in one will prevent the sinks from choking.
