SINK CABINET DRAIN SYSTEM
In one example, a sink cabinet drain system may include a sink cabinet, a faucet, a supply line, a custom-fit drain pan, and a gravity-drained cabinet waste line. The sink cabinet may support a sink basin. The faucet may be configured to direct water into the sink basin. The supply line may be configured to supply pressurized water to the faucet, the supply line being routed through the cabinet. The custom-fit drain pan may be disposed within the cabinet, beneath both the supply line and the sink basin. The upper surface of the drain pan may be sloped to drain to a collection orifice. A gravity-drained cabinet waste line may be configured to collect liquid from the collection orifice and deliver the liquid, via gravity, to a sewer system.
The present disclosure relates generally to hard piped drain systems. In particular, systems for automatically draining fixed cabinetry are described.
Known cabinetry systems are not entirely satisfactory for the range of applications in which they are employed. For example, the interior spaces of existing cabinets, such as sink cabinets, do not drain to hard-piped sewer systems. Water or other fluid that leaks or flows into these interior cabinet spaces flows out onto the floor and/or sits stagnantly in the interior space. Stagnant water in the interior space of the cabinet may go unnoticed for long periods and cause severe damage to the cabinet and/or the floor beneath it.
Thus, there exists a need for cabinetry drain systems that improve upon and advance the design of known cabinets. Examples of new and useful cabinetry drain systems relevant to the needs existing in the field are discussed below.
SUMMARYIn one example, a sink cabinet drain system may include a sink cabinet, a faucet, a supply line, a custom-fit drain pan, and a gravity-drained cabinet waste line. The sink cabinet may support a sink basin. The faucet may be configured to direct water into the sink basin. The supply line may be configured to supply pressurized water to the faucet, the supply line being routed through the cabinet. The custom-fit drain pan may be disposed within the cabinet, beneath both the supply line and the sink basin. The upper surface of the drain pan may be sloped to drain to a collection orifice. A gravity-drained cabinet waste line may be configured to collect liquid from the collection orifice and deliver the liquid, via gravity, to a sewer system.
The disclosed cabinetry drain systems will become better understood through review of the following detailed description in conjunction with the figures.

Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.
Throughout the following detailed description, examples of various cabinetry drain systems are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
With reference to
For example, system 10 collects liquid spilled or sprayed in the interior space 360 of cabinet 300 and drains it to the sewer system, thereby preventing damage to the cabinet and/or widespread flooding of the area surrounding the cabinet 300. Further, system 10 prevents backflow of gas and/or liquid from the sewer system into the interior space 360.
System 10 includes sink cabinet 300, a faucet 310, a drain pan 100, a cabinet waste line 114, and a check valve 118.
As can be seen in
Sink basin 320 may be drained by basin waste line 200. As shown, basin waste line 200 may include a gooseneck and/or plurality of fittings. Basin waste line 200 may be gravity drained.
As can be seen in
As described above, each of the hot and cold water supply lines 220, 210 and basin waste line 200 have various fittings. Each of these fittings has a potential to leak liquid into the interior space 360 of cabinet 300. In conventional sink cabinets, a leak from one of these fittings into the interior space of the cabinet may cause significant damage. However, drain pan 100 functions to collect any liquid that may leak from the piping above it, thereby preventing it from damaging the cabinet and/or flooding the area surrounding the cabinet.

As can be seen in
Check valve 118 may be disposed in the cabinet waste line 114. Check valve 118 may function to prevent backflow of liquid and or gas from the sewer system. Check valve 118 may be disposed downstream of tee 116. Thus, check valve 118 may prevent backflow from both cabinet waste line 114 and basin waste line 200.
