  • Patent number: 8904571
    Abstract: A portable toilet system is provided having an enclosed housing and including a tank upon which a toilet seat and bowl is positioned. The tank has two sections divided by a wall. Waste drops into the first section where it is accumulated for collection. The dividing wall does not extend to the top of the tank. The second section is initially filled with fresh water. A pump draws water through a hose or pipe submersed in the second section. That water is flushed into the toilet bowl to rinse waste into the first section. As the water in the second section is depleted, the liquid waste deposited in the first section overflows the dividing wall into the second section of the tank to recycle the liquid waste and extend the period before servicing of the system is necessary.

  • Patent number: 8239976
    Abstract: In one embodiment of the present system invention, there is provided a dividing module positioned in the holding tank of a toilet to separate the holding tank into a main portion and a reserve portion. The dividing module has a height lower than the full water level in the holding tank. The dividing module includes the ability to selectively connect the main portion and the reserve portion in fluid communication of each other. The embodiment allows an operator to press the handle arm an initial time to maintain the main portion and the reserve portion in substantially fluid separation of each other, such that water in the main portion is utilized to flush the toilet and wherein when the operator presses the handle a second time in the same manner as the initial time, the dividing module connects the main portion and the reserve portion in substantially fluid communication with each other, such that water in the reserve portion and the main portion is utilized to flush the toilet.

    Abstract: A toilet-flushing (1) device comprises a container (2) divided by an elastic diaphragm (3) with a direct unrestricted connection to a water supply under pressure at the lower part of the container (2), with a flushing valve (15) also in the lower part of the container. The water distends the diaphragm (3) so that when the flushing valve (15) is opened, the diaphragm (3) ejects the flushing water fast, allowing a small volume flush to effectively clear the toilet trap (2) and sewer. Extension of the diaphragm can be reduced by having two diaphragms (55), (56), each providing half the flush volume by their extension. Substantial water saving is enabled. A water pressure actuated valve (35) that is well adapted for application to this device is disclosed.

  • Publication number: 20020157177
    Abstract: A water saving toilet flushing system is disclosed having two substantially equally sized compartments contained within a single tank with each compartment containing a standard flush and fill control system including a water inlet connected to a water supply, a float control connected to the water inlet, a flush lever controlled by an exterior flush handle, and a flapper type outflow valve connected to the flush lever by a chain. The outflow of each compartment is through a Y-shaped outflow valve with one end in each compartment and an end connected to the toilet bowl. The compartments are sized such that the water from one compartment is sufficient to substantially remove liquid waste from the toilet bowl and each compartment is substantially similar in size so that either compartment may be used for the removal of liquid. Water from both compartments used together will substantially remove solids from the bowl. Accordingly, water consumption is reduced from that of a toilet using a standard tank.

    Abstract: A toilet has a toilet bowl and a flushing tank which accommodates a supply of flushing liquid for the bowl. The bowl, which discharges into a waste line, is connected to the flushing tank by a flushing pipe. A second pipe for evacuating odors from the bowl likewise leads from the bowl to the tank. This evacuating pipe has an open end in the bottom of the bowl and a second end in the tank. An air duct hooked into the waste line also extends into the tank and can be caused to communicate with the evacuating pipe when the toilet is in use. The air duct is provided with a blower which functions to convey odors from the bowl to the waste line via the evacuating pipe, flushing tank and air duct. A liquid seal cuts off communication between the air duct and evacuating pipe when the toilet is not in use to prevent backflow of odors from the waste line to the bowl. The liquid seal is located in the flushing tank and is established using the flushing liquid accommodated by the same.

  • Patent number: 4419772
    Abstract: A water saver for the water closet of a flush toilet, which allows the operator to vary the amount of water being used according to the requirements of the situation. A lever on the exterior of the water closet controls the egress of water from a separate secondary reservoir contained within the water closet. Varying the position of the lever varies the amount of water which escapes from a trap door on the secondary reservoir attached to the lever. When very little water is required for the flushing process the secondary reservoir remains undisturbed. However, if the entire amount of water contained within the water closet is required then the secondary reservoir will empty completely because of the position of the control lever. The amount of water that escapes from the secondary reservoir, which varies from all to none, is determined by the position of the trap door in relation to the walls of the reservoir, which varies the effective volume of the reservoir.

Piping also connects a source of fresh water to the fresh water chamber. A hand lever on the outside of the toilet operates a lever arm within the water tank which when it is raised upwardly actuates structure causing the buoyant valve to rise thereby letting fresh water into the gray water tank. Structure is also actuated in the gray water tank when the lever arm raises upwardly and this structure opens the flapper valve to release water from the gray water chamber into the toilet bowl for flushing thereof.
