  • Patent number: 10597859
    Abstract: A device for the disposal of human waste matter, specifically a toilet, is presented. This toilet incorporates elements designed to prevent both a loss of flushing efficiency and an extensive consumption of water, all while improving upon the basic functionalities of the toilet as such. These elements include specialized parts designed to both improve the efficacy of the “siphon jet” type toilet by precluding the possibility of aeration within certain critical components of the toilet system proper, as well as a specialized rim fed channel whose intersection of the filled jet channel always travels below the operating water level of the bowl, and a vacuum assisted flushing system, whose primary purpose is to enhance the power of the toilet's flushing action.

  • Patent number: 9920533
    Abstract: The present invention is to provide a system and a method for effectively preventing that gases/heat from an outlet are ascending from a gully and form ice, in addition to effectively drain liquids through a gully. The present invention is obtained by arranging a float so that said float and a portion of the gully define a closable opening for through flow, further arranged such that the float is preventing gases/heat from the outlet to ascend up from the gully and form ice and/or so that the float prevents that gas is drawn into the gully.

    Abstract: A system for controlling the duration and volume of a flow of water in a flush of a Toilet, which includes a buoyant flush valve which is non-automated in user actuation thereof to a raised open position. The system includes a converting element, for converting the buoyant flush valve to a non-buoyant flush valve which is non-automated in user actuation thereof to a raised open position. A programming element enables programming of a controlling time, for controlling the duration and volume of flow of water in a flush of a toilet. A controlling element is connected to the programming element and the non-buoyant flush valve, for retaining the non-buoyant flush valve in a raised open position upon non-automated user actuation thereof to the raised open position, and for releasing the non-buoyant flush valve from the raised open position for closing the non-buoyant flush valve, within the controlling time.

  • Publication number: 20110107505
    Abstract: A multifunctional toilet comprises a water storage device having a guide rail, a toilet seat and an arm assembly. The water storage device is provided with a water tank having a water inlet and a water outlet. At the water inlet is provided an inlet valve having a float ball, and at the water outlet is provided an outlet valve. The opening and closing of the inlet valve is controlled by a controller. The opening and closing of the outlet valve is controlled by a rope. When the water tank moves to its lowest position, the controller will close the inlet valve, and the rope will open the outlet valve. At the water outlet outside the water tank is provided an expansion discharge pipe. Such a multifunctional toilet is simple in structure and has the advantage of automatically flushing the toilet without the use of electricity.

  • Patent number: 7895684
    Abstract: A canister type flush valve has an upright cup-shaped hollow float working under buoyancy forces without a captured air volume that controls the valve during a flush cycle. Hooded bleed openings at a bottom wall of the float can be sized and numbered to selectively control the closuring timing of the valve. Baffles of the hood bleed openings redirect water bleeding into the float to prevent the water from spraying up against the top of the tank. The geometry of a seal retaining groove is designed to reduce leakage at the float/seal interface. For example, the groove has an annular wall with a compound profile forming a non-cylindrical, preferably serpentine, seal contact area. The seal is backed by a slotted flange located just above the retaining groove.

  • Publication number: 20100325787
    Abstract: A toilet multi flushing device consisting of an enclosed tank (3) filled with compressible plastic sheets (6). The tank (3) has a direct connection (1) to water supply at the bottom, an outlet at the bottom of the tank (3) with an external ball valve used as a flushing valve (10). When the valve (10) is opened the water is ejected at high speed to clear the bowl. It could be mixed with fresh air to form a mist flow. The mist streams clear the bowl. Fresh air could be substituted by the air from the trap (25) to create vacuum after the trap (25) to facilitate the clearing of the bowl.

  • Publication number: 20100251471
    Abstract: The present invention is related to toilet device. Specifically, the present invention is related to a gravity fed toilet device of mega low water consumption, since it only consumes one gallon per flush (gpf) or 3.8 liters per flush (lpf), which is highly desirable for users. Conventional gravity fed toilets require a water consumption above 1.03 gpf/3.85 lpf for them to be efficient, or they require special accessories to improve their efficiency. The present invention significantly overcomes this high water consumption by providing a mega lower water consumption toilet device (i.e., 1 gpf/3.8 lpf), which operates by means of a conventional gravity system, without needing any accessory or special fittings elements, and with performance results equivalent or superior to those required for the highest standards and the regulation of world market.

  • Publication number: 20100212079
    Abstract: An adapter cup for use in a multi-piece valve assembly, a universal flush valve assembly kit and a method of installing in a flush tank with a discharge hole. The kit has a first adapter cup, an additional adapter cup and a main body valve fitting. The adapter cups have substantially identical upper rims that are configured for attachment to the main body valve fitting. Each adapter cup has a lower cylindrical portion with a different outer diameter than that of the other adapter cup. The lower portion of one of the adapter cups is inserted into a discharge hole of like or substantially similar diameter. The main body fitting with an inlet and outlet is attached to the rim of the inserted adapter cup. A flapper is swingable relative to the main body fitting from a closed position abutting the outlet to an open position raised from the inlet. A single flush tank valve assembly can be installed into toilet tanks with different sized discharge holes.

  • Publication number: 20100170031
    Abstract: A flush valve assembly structure of a water tank is provided, and includes a valve seat, a guide rod, and a canister flush valve. The canister flush valve seals a flow path from an internal of the water tank to a toilet bowl, and may be lifted up to be separated from the valve seat to form a valve port. A water passage part is mounted on the canister flush valve, and a water passage post is disposed on the water passage part. A water inlet is disposed on the water passage post, which may be appropriately blocked by a block wall correspondingly disposed on the bottom wall. Meanwhile, a position of the water passage post may be adjusted to change a degree that the water inlet is blocked, so as to change a flow volume of flush water entering the canister flush valve from the water inlet.

  • Patent number: 7676858
    Abstract: A flush valve for a toilet has a valve body with a flow passage that narrows non-linearly down from the valve seat. The flow passage is formed by a surface that follows a polynomial expression so as to define a computationally derived flow profile that more closely follows the narrowing exhibited by falling water as it accelerates under gravity. The non-linear flow profile of the valve reduces the presence of air in the valve after a flush cycle is initiated so that greater flush efficiency can be achieved. The flush valve can also have a wide mouth overflow that narrows to improve flow in an overflow situation.
