ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to recessed dish drains for residential or commercial kitchen countertops.
BACKGROUND OF THE INVENTION
U.S. Pat. No. 4,998,306 of Klimke, discloses a recessed dish drain reservoir. It is next to a conventional sink basin. There are also two overflows in Klimke '306, which lead into a central drain, between the dish drain reservoir and the kitchen sink basin. They are identified in Klimke '306 as “overflows,” as opposed to “drains” or conduits.
In Klimke '306, the drain is a cascading drain over a bottom edge. In addition, the sunken drain board reservoir in Klimke '306 is not covered with a cutting board surface.
Furthermore, U.S. Pat. No. 5,915,851 of Wattrick, discloses a modular sink countertop with built-in dish drains, which can be flushed with nozzles. The dish drains in Wattrick '851 are not covered, and they are not shallow concave basins.
Covered cutting board surfaces are shown in U.S. Pat. No. 4,305,166 of Rose, which discloses a reversible sink cover for a sink which includes a decorated flat surface fitted to a sink well and having a dish draining rack of the reverse side. However in Rose '166 the dish rack is not built-in.
U.S. Pat. No. 4,480,343 of Drach also discloses a combination reversible drain and cutting board which includes means of adaptation for use with a dish rack. However, it also is not built into the countertop.
U.S. Pat. No. 5,815,855 of McKeehan discloses a sink cover which includes a flat surface for covering a sink's well and a hose with conduit for draining. However, it also is not built-into the countertop.
Moreover, U.S. Pat. Nos. Des. 324,903 of Sauter, Des. 322,474 of Dawkins and Des. 258,834 of Kinsey all disclose sink countertops with built-in drainboards. However, they are not optionally covered with flat surfaces to act alternatively as cutting board work surfaces.
In addition, U.S. Pat. Nos. 4,589,150 and 5,105,485, both of Sciabarassi, 4,854,537 of Welch, Des. 288,375 of Okami and Des. 267,125 of Luoma disclose portable dish drain boards.
OBJECTS OF THE INVENTION
It is therefore an object of the present invention to provide a recessed dish drain for drying dishes upon a sink countertop.
It is also an object of the present invention to maximize surface workspace of a kitchen countertop.
It is yet another object of the present invention to provide a dish drain, which flows into the main sink drain of a kitchen sink, without having to cascade over the upper edge of a kitchen sink basin.
It is further an object of the present invention to provide a covered dish drain, which can be hidden from view when not in use.
It is yet another object of the present invention to provide a dish drain that automatically rinses.
It is yet a further object to dispense with the need for a dish drain overflow hanging over the edge of a kitchen sink countertop.
It is yet another object to improve over the disadvantages of the prior art.
SUMMARY OF THE INVENTION
In keeping with these objects and others which may become apparent, the present invention is a recessed dish drain for a residential or commercial kitchen sink countertop. It includes a water drainable grid upon which dishes to be dried are placed. Below the grid is a shallow, preferably concave drain reservoir basin, connected by preferably a flexible water conduit hose to the main sink drain.
Moreover, the concave drain reservoir basin may have an optional collar flush system, whereby water is flushed out and down the shallow concave reservoir basin, to clean it of debris and topical germs. In addition, the collar flush system may be used with conventional residential or commercial sink basins.
Furthermore, an optional flat stainless steel or plastic lid is provided as an extra work surface space when the drain is not in use.
The drain is through a bottom conduit, rather than over a cascade edge.
