    Abstract: An apparatus for controlling overflows is provided. The apparatus for controlling overflows may comprise an interior bowl including a waste receptacle and one or more water outlets connected to a water tank. The one or more water outlets may be configured to flush the interior bowl through a primary drain. Additionally, the apparatus for controlling overflows may include an exterior bowl, which may surround the interior bowl. The exterior bowl and the interior bowl may be separated by a gap. The gap may be configured to capture overflow water from the interior bowl when the primary drain malfunctions. Once the overflow water is captured by the gap, it may then be emptied into one or more containers configured to collect the overflow water.

  • Publication number: 20120246816
    Abstract: Disclosed is a rotatable urinal combined with a toilet. The rotatable urinal includes, in a upper part thereof, a urinal drain tube of a U-shape trap, a urine connecting tube which is rotatable and height adjustable, a lid, and a water supply tube and a water supply valve to disperse the cleaning water. Where, the urinal drain tube is formed in both parts of the top surface of a rear part of a toilet body as one body type with the toilet body for users to assemble the rotatable urinal in any of the left side and right side. The rotatable urinal helps to use much less water by assembling and installing the rotatable urinal in the toilet separately.

  • Publication number: 20120186009
    Abstract: The present invention provides a toilet assembly which includes a case and a toilet bowl. The toilet bowl extends from a bottom of the case and toward a direction away from the case, wherein the case is disposed with at least one partition. The partition divides an interior of the case into a first reservoir area and a urinal area. The first reservoir area is adapted to reserve water. At least one surface of the urinal area is formed with an opening, and the opening is adapted for a user to urinate. Thereby, the urinal area can be formed in one piece with and on one side of the toilet assembly. Consequently, it can save the use of water consuming when male users urinates, and it can save the space in the lavatory. Further, the male users can urinate in front of the urinal area without opening the seat lid.

  • Patent number: 8001625
    Abstract: An efficient dual-use toilet that provides a simple, easy-to-use and reliable solution to the problem of wasted toilet flush water is disclosed. The improved toilet provides a two-compartment toilet bowl, wherein the main bowl is used for solid waste and a hydrophobic secondary bowl is used for liquid waste. When only the secondary bowl is used, the toilet does not require flushing. When the toilet is flushed for solid wastes, water simultaneously cleanses the secondary bowl. Importantly, the drain line for the secondary bowl is configured such that during the flush cycle air is prevented coming back through the sewer system and into the household. The system is fully automatic and provides a very easy-to-learn “flush and forget” solution for the user. The amount of water flushed to the sewer system is greatly reduced, and consequently so is the burden on fresh water supply systems as well as the energy cost in required to deliver water.

  • Publication number: 20100037379
    Abstract: A special toilet tank equipped with a pivoting urinal, to facilitate the collection of urine from a standing male person. This will protect surrounding floors, walls and structure, from urine spray. The folding urinal is moveable from a stored position in the special tank enclosure to a position above the toilet bowl. The urine drops directly into the toilet bowl eliminating the need for a separate drain line. A water line passes through a position valve, to provide rinse water inside the urinal to flush the urine from the inside surfaces. The rinse water also drops into the bowl during flushing. When the urinal is in the stored position, the position valve prevents flow of water to the urinal during normal flushing.

The waterless urinal has a urinal bowl having a drain therein. The toilet bowl and urinal bowl are formed in one dual bowl toilet body. A drain tube connects the urinal drain to the toilet siphon outlet of the toilet bowl for draining urine from the waterless urinal and a floatable drain cover is positioned in the waterless urinal bowl to cover the drain opening in the absence of liquid in the bowl and uncovers the urinal drain opening when liquid in the urinal bowl floats the drain cover. The drain cover can be a floatable ball, such as a hollow plastic sphere, while the urinal ball is shaped to direct the free-floating bowl over the drain whenever there is no liquid in the urinal bowl. The urinal bowl has a bottom portion shaped to guide the floatable drain cover over the drain opening.

  • Patent number: 5390374
    Abstract: A water conserving urinal for male and female use attachable to a toilet. The urinal includes a urinal bowl which is supported on a flexible member secured at its lower end to a pivot member. Water is supplied to the bowl from the toilet water supply line via a flexible supply line. A flush valve is provided in the water line and distributes a low volume of water around the interior of the bowl through an interiorly extending flush ring. A waste line extends from discharge of the urinal bowl through the center of the flexible support and through the toilet bowl to the sewer. Fluid waste is thus discharged directly to the sewer line without the necessity of a full flush of the toilet resulting in substantial water savings. The pivot support and flexible support permit the urinal to be moved forward to the desired position and height to accommodate the physical requirements of the user.
