Benefits of technology

[0022]Further, as the overflow opening is located at the top of the basin, the sink can hold more water than a similarly-shaped sink having an overflow opening punched in the side wall of the basin at a lower position. For those tasks which the user is intentionally filling the sink with water (e.g., soaking of clothing, preparing a reservoir for shaving, and the like), this improves the functionality of the sink, better maximizing the depth of the basin.

Problems solved by technology

However, in some cases, the basin of the sink may become overfilled with water.
This can occur if the opening to the drain is blocked while the water is still running.
This can occur due to the drain being left closed too long when the water is running, or the speed of the water exceeding the drainage capacity of the drain due to clogging or the like.
However, from a design perspective such overflows can be ornamentally disruptive.
However, that can significantly reduce the volume of water the basin can hold before the overflow starts.

Embodiment Construction

[0028]Referring first to FIG. 1, a sink assembly 10 is shown including a counter 12 and an under-counter mountable sink 14 mounted under the counter 12. The under-counter mountable sink 14 can be made from any one or more of a number of materials including ceramic, metal, and / or plastic. A faucet and one or more control handles (not shown) may be positioned on top of the counter 12, adjacent sink 14.

[0029]As best seen in FIG. 2, the under-counter mountable sink 14 has a basin 16 having walls 18 extending down from an upper rim 20 to a drain opening 22. A drain passage 24, best seen in FIG. 3, extends down from the drain opening 22. The drain passage 24 typically is then connected to a sewer line in a manner well understood by the art.

[0030]The drain passage 24 could house a controllable plug or stop that can be actuated via a pull-up knob or other means to selectively seal the drain opening 22. By sealing the drain opening 22, a user can prevent water from draining out from the bott...

Abstract

A sink assembly provides an enhanced overflow system for an under-counter mountable sink. The sink has an overflow cutout with an open top formed adjacent an upper rim of the basin of the sink. When the sink is mounted to the bottom surface of a counter top, the sink and counter together form an overflow opening, thereby permitting the overflow to be more easily concealed and increasing the fill capacity of the sink. Methods of installing such sink assemblies are also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]Not applicable.STATEMENT OF FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]This invention relates to sinks. More particularly this invention relates to undercounter mountable sinks provided with improved overflow structures.[0004]Conventionally sinks have a rimmed basin mounted to a counter top. Water from a faucet or other water supply is directed into the basin, where it collects and typically then flows down a lower drain.[0005]However, in some cases, the basin of the sink may become overfilled with water. This can occur if the opening to the drain is blocked while the water is still running. This can occur due to the drain being left closed too long when the water is running, or the speed of the water exceeding the drainage capacity of the drain due to clogging or the like.[0006]To prevent the spilling of water over the rim into the room in such a situation, many sinks have an integrall...
