  • 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: 8142572
    Abstract: A lavatory pan washing apparatus includes a water supply unit supplying washing water into a rim so that a whirling flow is formed in a lavatory bowl, an air inlet pipe connected to a water discharge channel continuing to the downstream side of a water sealing portion of a pan, an air sucking unit sucking air through the pipe from the channel, and a control unit configured to activate the water supply unit at a time of washing of the pan so that the washing water is supplied into the water sealing portion. The control unit is configured to start activation of the air sucking unit after rise of a water level in the lavatory bowl, so that air is sucked through the pipe from the channel. The control unit is configured to deactivate the water supply unit after air has flowed through the air inlet pipe into the channel.

  • Publication number: 20110030802
    Abstract: A fresh flush recycling toilet system, which may be portable, is provided having an enclosed housing and including a tank upon which a toilet seat and bowl is positioned. The tank has a vertically oriented solid wall extending across the bottom of the tank the full distance between the front and rear walls forming two sections in the tank. Waste material drops, under the influence of gravity, into the tank where it is accumulated for collection. The vertically oriented solid wall does not extend fully to the top of the tank. In its initial state, the second section of the tank is filled with fresh water. A pump draws water through a hose submersed in the second section of the tank. That water is flushed into the toilet bowl to rinse waste down through the toilet bowl into the first section of the tank.

  • Patent number: 7877822
    Abstract: A non-water lavatory flushing device consists of a electrical four-way valve, which one of its exit is connected with the exit of the side wall of the valley at the back of the toilet pan for collecting the feces. The three exits are connected with the central part of the toilet pan, feces collecting box and the flushing liquid collecting box through a feces dispersing pipe, a feces collecting pipe and a urine collecting pipe. The non-water lavatory flushing device of the invention uses a four-way valve to replace the feces dispersing pipe magnetic valve, feces collecting pipe magnetic valve and urine collecting pipe of the prior art. The dispersed feces liquid and urine in the feces dispersing pipe, feces collecting pipe and urine collecting pipe is controlled by the four-way valve respectively. Then the structure is simplified and the cost is decreased. Furthermore, as the four-way joint is cancelled, the problem of wrong flowing of the leaving liquid is solved.
