  • Patent number: 9737176
    Abstract: A vessel, such as a bathtub or sink, has a soap dish recessed in the inside wall of the vessel. The recessed soap dish is connected to the overflow drain of the vessel. The soap dish is large enough to receive a bar of soap. The overflow drain holes in the bottom of the soap dish are small enough to prevent the bar of soap from falling into the overflow drain. The recessed soap dish can be placed in the front of the vessel so that the soap dish is hidden from view. The front of the sink is the surface opposing the faucet. The front of the bathtub is the surface that a bather steps over to enter the bathtub.

  • Patent number: 9315978
    Abstract: Food preparation sinks are disclosed which have an integral raised work area that is rinsed by an automatic system. Food waste or the like present in that area can be washed into a sump above a drain, and the weight of the waste and water in the sump is enough to automatically drive them through a baffle to a garbage disposal, without requiring the baffle to be manually opened. An automatic controller system coordinates water flow and garbage disposal operation, and the water supply can be linked to the sink below the sink rim to save counter top space. In some forms multiple rinsing nozzles are provided which pulse in altering fashion.

  • Patent number: 6353944
    Abstract: A wash basin, as for a domestic bathroom, has normal inlet water faucet(s) and spigot(s) fitted at or above its top and a normal outlet or drain pipe at its bottom. The basin also has a peripheral inlet flow channel formed below its top rim, for creating a smoothly-flowing film of water cascading down the interior sides of the basin to the outlet. This flowing water film intercepts detritus such as shaving cream, toothpaste, and soap, preventing it from sticking to and soiling the interior of the basin. The basin preferably also has a peripheral overflow channel formed in its side wall adjacent but spaced from the peripheral inlet channel and communicating to the drain below any drain plug or stopper that may be used. The inlet flow channel preferably has a separate water supply and control so that it may be used either separately from or in addition to the regular water supply and so that it may alternatively be left off even while the regular water faucet(s) and spigot(s) are in use.

    Abstract: To provide for positive sanitary separation of water spilling or overflowing from a washing sink unit (1), a cleaning sink unit (2) and a third water receiving unit (3), which may be formed as a sink unit or as a drain board, the second unit, located between the first and the third, is surrounded by a raised zone which merges with a forward region of a water retention rim (4) surrounding all the sink units, the raised region (5) terminating short of the rear edge region (19) of the sink unit, and leaving with the water retention rim (4) adjacent the rear edge region a gap (7). A drain and overflow opening (8) is located in the gap. Surfaces of the sink which may be essentially planar are pitched towards the overflow and drain opening, so that any water splashing or overflowing from any one of the three units or regions (1, 2, 3) will drain off into the overflow without flowing back into another one of the units or regions.
