Field of invention

The present invention relates to the field of gravity-powered toilets for the removal of human waste and other excrement. The present invention also relates to the field of toilet seats operated by a primed water delivery system to improve performance.

A toilet is known for removing feces such as manure. Gravity type toilets generally have two main parts: a tank and a bowl. The tank and the bowl may be separate parts that are joined together to form a toilet system (commonly referred to as a two-part toilet) or may be combined into one integral unit (typically a single knob).

The tank, which is generally located on the back of the bowl, houses water used to start flushing excreta from the bowl to the sewer line, as well as to recharge the bowl with fresh water. When the user wishes to flush the toilet, the user pushes down the flush lever on the outside of the tank, which is connected to the movable chain or lever, from the inside of the tank. When the flush lever is depressed, it lifts the flush valve to move the inner chain or lever of the tank to act to open, causing water to flow from the tank into the bowl, thus initiating flushing of the toilet.

There are three general purposes to be served in the flush cycle. The first objective is the removal of solids and other excrement into the drain line. The second objective is cleansing of the bowl to remove any solid or liquid excrement that has settled or adhered to the surface of the bowl and the third purpose is to provide a pre- (pre-flush) to exchange the volume of water. The second requirement, i.e. cleaning of the bowl, is generally achieved via a hollow rim extending around the perimeter of the toilet bowl. Some or all of the flush water is directed through the rim channel and flows through openings located therein to disperse water over the entire surface of the bowl and achieve the required cleaning. A third requirement is to recharge the bowl with clean water to restore the sealing depth to the backwash of the sewer gas and make it ready for subsequent use and flushing.

Gravity type toilets can be classified into two general categories: wash down and siphonic. In a washdown toilet, the water level in the bowl of the toilet is always kept relatively constant. When the flush cycle begins, water flows from the tank and overflows into the bowl. This causes a rapid rise in water level, and excess water flows over the weir of the trapway and conveys the liquid and solid excrement therewith. At the end of the flush cycle, the level in the bowl naturally returns to an equilibrium level determined by the height of the dam.

In a siphon toilet, the trapway and other hydraulic channels are designed such that the siphon is initiated within the trapway when water is added to the bowl. The siphon tube itself is an inverted U-shaped tube that draws water from the toilet bowl to the wastewater line. When the flush cycle begins, water flows over the dam in the trapway faster than it can flow into the bowl and exit the outlet to the drain line. Sufficient air is eventually removed from the descending leg of the trapway to initiate the siphon, which in turn draws the remaining water from the bowl. The level in the bowl is therefore sufficiently lower than the level of the dam when the siphon is interrupted and the individual mechanism is used to recharge the bowl of the toilet at the end of the siphon type flush cycle to reset the protective & Needs to be provided.

Siphon and wash-down toilet seats have unique advantages and disadvantages. Siphon toilets tend to have smaller trapping ways that can cause clogging due to the need to remove most of the air from the downward legs of the trapway to initiate the siphon. Washdown type toilets can function with large trapways, but generally require a smaller amount of pre-flushing water in the bowl to achieve the 100: 1 dilution level required by the plumbing code in most countries. (I.e., 99% of the pre-flush water volume in the bowl must be removed from the bowl and replaced with fresh water during the flush cycle). This small pre-flush volume is specified as a compact "water spot ". The water spot or surface area of the pre-flush water in the bowl plays an important role in maintaining the cleanliness of the toilet. Large water spots increase the likelihood that the fecal material will come in contact with the water before contacting the ceramic surface of the toilet. This reduces the adhesion of the excrement material to the ceramic surface, making it easier for the toilet to clean itself through the flush cycle. Thus, the wash-down toilet with its small water spot frequently requires manual washing of the bowl after use.

Siphon toilets have the advantage of being able to function with a larger pre-flush water volume and a larger water spot within the bowl. This is possible because the siphon action pulls most of the pre-flush water volume from the bowl at the end of the flush cycle. As the tank is refilled, portions of the refill can be directed into the bowl to return the pre-flush water volume to its original level. In this way, a 100: 1 dilution level required by a number of piping standards is achieved, even if the starting volume of water in the bowl is significantly larger than the flushing water coming out of the tank. In the North American market, siphon toilets are widely accepted and are now regarded as the accepted form of standard toilet. In the European market, wash-down toilet is still more acceptable and popular, while both versions are common in Asian markets.

Gravity type siphon toilets can also be classified into three general categories depending on the design of the hydraulic channel used to achieve the flushing action. These categories are: non-jetted, rim jetted, and direct jet.

In a non-jetted bowl, all the flush water exits the tank into the bowl inlet area and flows into the rim channel through the main manifold. The water is distributed around the main body of the bowl through a series of holes located beneath the rim. Some of the holes may be designed to be larger in size to allow more flow of water into the bowl. A relatively high flow rate is required to displace sufficient air in the downward leg and flood the water over the dam of the trapway sufficiently fast to initiate the siphon. Non-jet type bowls are usually suitable for good performance with respect to cleaning the bowl and replacing the pre-flush water, but the performance is relatively poor in terms of bulk removal. The supply of water to the trapway is inefficient and turbulent, which makes it more difficult to charge the downward legs of the trapway and start a strong siphon. Thus, the trapway of a non-jetted toilet is usually smaller in diameter and includes a curved portion and a constricted portion designed to impede the flow of water. Without a smaller size, bend, and shrinkage, a strong siphon will not be achieved. Unfortunately, smaller sizes, curves, and constrictions cause poor performance in terms of bulk excrement removal and frequent clogging, which is an extremely unsatisfactory condition for end users.

Toilet designers and engineers have improved the removal of bulk fecal material from siphon toilets by incorporating "siphon jets". In a rim jet toilet bowl, the flush water exits the tank, flows through the toilet inlet area and into the rim channel through the main manifold. A portion of the water is dispersed around the main body of the bowl through a series of holes located beneath the rim. The remainder of the water flows through the jet channels located in front of the rim. This jet channel connects the rim channel to the jet opening located in the sump of the bowl. The jet opening is dimensioned and positioned to deliver a strong stream of water directly from the opening of the trapway. When the water flows through the jet opening, it serves to fill the trapway more efficiently and rapidly than can be achieved in a non-jetted bowl. The flow of water to this more energetic and rapid trapway allows the toilet to be designed with a larger trap-way diameter and fewer bends and constrictions, which in turn improves the performance of bulk excrement removal compared to non-jetted bowls. Since a smaller volume of water flows out of the rim of the rim jetted toilet, but the water flowing through the rim channel is compressed by the upstream flow of water from the tank, the bowl cleaning function is generally acceptable. This allows the water to exit the rim hole with higher energy and to perform a more effective task of cleaning the bowl.

Rim jet type bowls are generally superior to non-jet types, but the long path through which water travels through the rim to the jet opening dissipates and wastes a lot of available energy. Direct jet bowls have been improved in this concept and can deliver even higher performance in terms of bulk elimination of fecal matter. In a direct jet bowl, the flush water exits the tank, flows through the bowl inlet and through the main manifold. At this point, the water is divided into two portions: a portion that flows into the rim channel through the rim inlet port having the primary purpose of achieving the desired bowl cleaning, and a "direct jet " linking the main manifold to the jet opening in the sump of the toilet bowl. Quot; channel "through the jet inlet port. The direct jet channel may take a different form, sometimes unidirectional, or "dual feed" around one side of the toilet, wherein the symmetrical channel proceeds along both sides connecting the manifold to the jet opening. As with the rim jet bowl, the jet openings are dimensioned and positioned to deliver a strong stream of water directly from the opening in the trapway. When the water flows through the jet opening, it serves to fill the trap way more efficiently and rapidly than can be achieved in a non-jet or rim jet type bowl. The flow of water to this more energetic and rapid trapway allows the toilet to be designed with a larger trap-way diameter and more minimal bends and constrictions, which in turn makes it possible to reduce the performance of bulk excrement removal compared to non-jet and rim jet- .

While direct jet bowls present a significant portion of the related art for bulk removal of current feces, there is still a major area for improving toilet performance. Government agencies are constantly asking water users to reduce the amount of water they use. A great deal of recent focus has been on reducing the water demand required by the toilet flushing operation. To illustrate this point, the amount of water used in a toilet for each flush was reduced from 7 gallons / flush (before the 1950s) to 5.5 gallons / flush (by the end of the 1960s), 3.5 gallons / flush Has been gradually reduced by the organ. The 1995 National Energy Policy Act of 1995 requires that toilet seats currently sold in the United States use quantities of only 1.6 gallons / flush (6 liters / flush). Regulations have recently been passed in California requiring further lowering of water usage to 1.28 gallons / flush. The 1.6 gallons / flush toilet seat currently described in the patent literature and commercially available loses its ability to consistently siphon when pushed by these low levels of water consumption. Thus, the manufacturer will be forced and will continue to be forced to sacrifice performance and reduce the trapway diameter without the development of improved technology and toilet design.

Many inventions have been aimed at improving the performance of a siphon toilet through optimization of the jet-type concept directly. For example, in U.S. Patent No. 5,918,325, the performance of a siphon toilet is improved by improving the shape of the trapway. In U.S. Patent No. 6,715,162, performance is enhanced by the use of flush valves having a radial inlet and asymmetric flow of water into the bowl.

U.S. Patent No. 8,316,475 B2 describes compressed rim and direct feed jet configurations that allow for proper siphoning and improved cleaning for use with low volume water that meets current environmental use standards.

U.S. Patent Application Publication No. 2012/0198610 Al also discloses a high performance, high-performance, high-performance, high-performance, high-performance, The toilet is starting. U.S. Patent No. 2,122,834 discloses a toilet having a hydraulic manifold and an air manifold for introducing air into the toilet flush cycle to terminate the siphon action and prevent backflow into the system. Other inventions are attempting to address the performance between rim and jet by dividing the toilet tank into individual sections. See U.S. Patent No. 1,939,118.

When the flush volume is compressed to less than about 6.0 liters, minimizing turbulence and flow restrictions within the internal channels of the toilet is of utmost importance. One of the most important factors in minimizing turbulence and flow restrictions is the management of air occupying the rim and jet channels before the initiation of the flush cycle. If it is not possible for the air to escape the system prior to the oncoming rush of flush water, the air will continue to occupy the space within the channel and limit the flow. U.S. Patent No. 5,918,325 describes a toilet comprising an air discharge means, a jet channel connecting the jet channel to the rim and including a passage through which air escapes from the jet channel into the rim during flushing. U.S. Patent Application Publication No. 2012/0198610 Al also discloses a toilet having a downstream communication port that allows air and / or water to pass between the jet channel and the rim channel.

There remains a need in the art to further improve siphon toilet performance and to manage pre-flushing air, especially occupying the jet channel (s). There is also a need in the art for a toilet that improves the aforementioned drawbacks of the conventional toilet, by preventing clogging during flushing without sacrificing flush performance and allowing significantly improved cleaning. These toilets must also still comply with water conservation standards and government guidelines, while providing adequate siphons for low water consumption for various trapway geometries.

As used herein, the terms "inner" and "outer", "upper" and "lower", "forward" and "rear", "front" Words such as "downward" and similar purposes are intended to assist in understanding the preferred embodiments of the present invention with reference to the accompanying drawings as to the orientation of the toilet assembly as shown, It is not intended to limit the scope of the present invention to the preferred embodiments as shown in the drawings. Embodiments 10, 1010, 110, 210, 310, 410, etc. of the present disclosure may be implemented using similar reference numerals to refer to similar features of the present invention as described herein and illustrated in the figures It will be appreciated by those of ordinary skill in the art that, based on the present disclosure and the accompanying drawings, it will be understood by those of ordinary skill in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention, It should be understood that it should be applicable to the example.

In the present invention, it is preferred to include a jet channel by isolating the fluid flow introduced into the bowl assembly for transferring different fluid volumes from the rim valve, such as a rim flush valve, and the jet flush valve, A siphon flush toilet assembly is provided that is operable to maintain an intrinsically-pleated closed jet fluid path. This provides more robust performance compared to standard gravity flush siphon toilets that work with air-filled jet channels and must emit air to minimize turbulence and flow restrictions.

The toilet bowl assembly of the present invention has a closed jet flow path including the jet channel (s) in the toilet bowl assembly outside the bowl. The jet channel (s) may include a bowl mold geometry including an optional jet manifold, as long as the closed jet flow path receives fluid from the jet valve outlet into the jet inlet port and into the jet channel and through the jet channel to the jet outlet port , It may have various configurations and extension areas, additional ports or side channels, and the like. The closed jet flow path maintains the jet channel in a continuously primed state and substantially isolates it, thereby helping to prevent air from entering the jet channel. (2) closing the jet channel flush valve before the level in the tank drops to a level of the level of opening of the flush valve, (3) by closing the jet channel flush valve, In one embodiment, the jet channel (s) and any other jet path, which may include setting the sealing depth in the jet trap within the sump region to assist in blocking air entry into the jet channel outlet, And / or (4) the level in the jet trap is lowered to a level that allows air to travel upward again into the jet channel, and / or (4) to help prevent airflow from entering the optional jet manifold when used, and / ≪ / RTI > and to assure that the assembly is not damaged.

Generally, the ratio of the volume of the fluid to the rim relative to the volume of fluid in the jets also affects the toilet performance. In a typical conventional siphon jet type toilet, about 70% of the flush water is required to power the jet and initiate the siphon, leaving only about 30% to clean the bowl through the rim. In the priming water toilet of the present disclosure, much less water is required to initiate the siphon, which allows more water to be used to clean the bowl. Applicants have determined that more than about 50% or more flush water can be introduced into the rim for significant improvement in bowl cleaning. In a preferred embodiment, greater than about 60% and greater than about 70% water can be introduced into the rim.

In addition to the aforementioned factors, another method for maintaining a sufficient sealing depth of water in the sump region and / or preventing back flow of air from the sump into the jet channel is to remove water from the jet channel, To maintain a lower flow rate. For example, initiating and maintaining a siphon in a trapped way of approximately 54 mm in diameter with a dam-filled bowl (i.e., excess water present to contribute to the siphon) Volumetric flow rate is required. Which is converted to a linear flow rate of 127 cm / s across the jet outlet port area of 7.47 cm < ^{2 &} gt ;. Larger trapway sizes will require higher flow rates to initiate and maintain the siphon, and smaller trapways will require smaller values. When the flow rate from the jet is reduced to less than about 950 ml / s, the siphon will be shut off. About 950 ml / s is less than, but the volumetric flow rate of the jet from about 175 ml / s exceeds keeping (that is, a linear flow rate of 23.4 cm / s through a 7.47 cm ² area of a jet outlet port), the air in the jet channel closed Will not enter. When the bowl is fully charged to the level of the trapway dam, the flow from the jet can be stopped without losing the priming as long as the top of the jet channel is located below the dam of the trapway.

Controlling such flush valve operation for the jet flush valve and the rim flush valve can be done in a number of ways. One approach is through the use of electromagnetic valves, as disclosed in U.S. Patent Application Publication No. 2009/0313750 and U.S. Patent No. 6,823,535, which are incorporated herein by reference. This valve control method may also be accomplished through a pure mechanical method, for example by a modification to a dual inlet flush valve, such as that disclosed in U.S. Patent No. 6,704,945, which is incorporated herein by reference in its entirety. Alternatively, a balanced flush actuating bar may be used for optimal performance of the two flush valves in sequence, as described herein.

The flush actuating bar may be connected to the pivot load and handle, or other flushing actuator, using an adjustable flush connector. The adjustable flush connector provides an adjustable connection to compensate for differences in the position of the pivot rod relative to the valve assembly within the toilet. Compensation allows most valve assemblies, flush operating bars, and / or pivot rods to be compatible with each other. The adjustment provided by the adjustable flush connector may include longitudinal movement along its length, rotation about its longitudinal axis, and / or rotation about its transverse axis.

Also, as will be described in greater detail below, system performance can be improved by providing a "peelable" valve cover to facilitate self-priming of the jet itself. The cover acts to reduce the actuation force required to open the jet flapper. In the present invention, when the jet channel (s) is primed, a force of more than two times greater than that of a conventional flapper valve is required due to the weight of water both above and below the flapper. By peeling off the cover, the seal is broken and some water is released while the air moves backward, so that the cover is opened more easily. In addition, during the initial priming water supply, when the valve is closed, the jet is filled with air, and when the flapper is suddenly opened, the flushing water is ejected too quickly and the air in the jet channel (s) It may not be sufficiently discharged according to the geometry of the substrate. In addition, embodiments of the present disclosure provide a primed water jet type closed jet path, so that when the toilet requires plunging, an optional non-return flow prevention device may be provided on the jet flush valve, as described further below. have.

A preferred valve cover structure for use with a "peelable" valve cover may optimize valve performance. In particular, the locking element may be provided on the seal to prevent dislocation of the seal from the valve cover. Also, to maintain consistent flush performance, a valve assembly may be provided that is linked to each other using a linkage device. Such valve assemblies may be used to ensure proper and consistent alignment between valve bodies over time.

Stopping entry of sufficient post-flush depth and / or water into the sump region through the jet outlet port and into the closed jet fluid path within the sump region also prevents the siphon from flowing through the rim channel in a more traditional toilet design Or by maintaining the flow of water to the rim shelves within the rimless toilet. Since the toilet system described herein includes a separate channel and a valve mechanism for controlling the flow of rim and jets, the system can be designed to continue to flow through the rim inlet port during siphoning. The flow of water to the rim inlet port is preferably sufficient to maintain a water level in the sump region that exceeds the height of the jet outlet port, but is insufficient to maintain the siphon within the trapway. In this way, additional assurance can be provided to maintain the jet channel without air, thereby reducing the dependence of the sealing depth in the sump region. It should be noted that the flow through the jet and rim may also be used together to maintain a sufficient post-flush depth in the sump region.

The relevant area where the present invention provides an improvement over the prior art is in a high efficiency siphon toilet with a flush volume of less than 6.0 liters, and preferably less than 4.8 liters. Embodiments of the toilet bowl assembly of the present invention described herein are capable of delivering about 6.0 liters / flush or less in a single flush toilet and / or double flush toilet assembly while still delivering excellent bowl cleanliness at reduced water usage, It is possible to maintain resistance to clogging with the current toilet with less than 4.8 liters / flush. As much less water is required through the jet channel to initiate the siphon, the priming water toilet assembly embodiments herein are capable of functioning up to about 4.8 liters per flush, preferably less than about 3.0 liters per flush And a very high efficiency toilet which can function at about 2.0 liters per flush.

Moreover, the second relevant area where the present invention provides an improvement over the prior art is in a siphon toilet with a larger trap way. By changing the size of the trapway, water consumption and toilet performance are significantly affected. In the present invention, the toilet bowl assembly is provided with a variety of traps, because of limitations on the flow achieved through the closed jet fluid path including the priming feed manifold and the priming water jet channel in the preferred embodiment and the reduction of turbulence, It is possible to maintain the priming water in the siphon toilet of the size and volume of the way, which allows the toilet bowl assembly to maintain good flushing and cleaning capabilities.

In order to achieve maximum potential performance of the toilet system of the present invention, the closed fluid jet path must be "primed watering ", i.e. filled with water and containing little or no air. When the closed fluid jet path and the jet channel comprise a significant amount of air, the closed jet channel can achieve the maximum potential performance of the system, as may be the case after initial installation of the toilet or after major repair or maintenance. It must be primed before it can become. In order for priming to occur, two basic requirements are: (1) water must be allowed to flow into the closed fluid jet path at a higher rate than it can exit the closed jet channel; and (2) It must be ensured that the air contained in the jet flow path is provided with a flow of water through the flow of water into the closed jet channel, or a route of escape to the flow of water.

The simplest way of priming a closed jet channel, which can be termed "passive priming water ", is to remove the jet from the jet outlet port (s), leaving the rim valve in a closed state, To open the flush valve assembly. The jet flush valve must remain open until air bubbles are no longer visible as escaping from the channel into the tank, at which point the jet flush valve may be closed and the jet outlet port not blocked. Upon recharging the tank, the system should then be completely primed and ready for use with maximum performance potential. In a preferred embodiment, the system is designed to "self priming water" over multiple initial flushes after loss of priming or installation after other unforeseen reasons (maintenance, repair, etc.). To self priming water, the same two requirements must be met, but they are system specific. Guaranteeing a self priming water supply system is mostly a function of the geometry and design of the jet flush valve, the closed fluid jet path including the jet channel, and the jet exit port. As will be described in greater detail below, the jet flush valve may preferably be a radial flush valve that allows a high flow rate into the closed jet channel and increases the flow rate (see, for example, 8,266,723). In most closed jet channel designs, the last part of the air trapped in the jet channel is likely to rise to a space beneath the flapper (or other opening mechanism) of the jet flush valve. Thus, the valve design should also facilitate the escape of this remaining air. As will be described below, progressively opening valves, such as the flapper that can be stripped, can restrict the flow of water to one side of the valve and facilitate escape of air around the flow. Certain patterns or ribs in the throat of the flush valve can likewise facilitate this escape of air.

1 to 15, 17 to 19, and 29 to 34 illustrate a first embodiment of a toilet bowl assembly, generally referred to herein as an assembly 10. The assembly 10 includes at least one jet flush valve assembly 70 having a jet flush valve inlet 71 and a jet flush valve outlet 13. The jet flush valve body 21 extends between the inlet 71 and the outlet 13 to form an internal flow path. The jet flush valve assembly may have a variety of configurations and may be any suitable flush valve assembly known or to be developed in the relevant art. Preferably, this is not only for the purpose of explaining the use of such a valve and the cover with the flotation, but also in connection with various embodiments of the jet flush valve shown in Figures 35-68 and described below, Lt; RTI ID = 0.0 > 2014/0090158, < / RTI > As shown in Figures 1 and 2 and Figures 7 to 11, the jet flush valve assembly 70 is configured to control the flow through the jet flush valve assembly to a shorter valve height < RTI ID = 0.0 > Profile where the rim valve is described herein with respect to assembly 80). Each of the rim flush valve assembly 80 and the jet flush valve assembly 70 preferably has a cover 115 that preferably has a floating portion 117 attached thereto via a chain 119 or other linkage. As described in co-pending U.S. Patent Application Publication No. 2014/0090158, these features help to provide advanced performance and buoyancy control in certain flush valve designs. It should be understood, however, that other flush valve assemblies may be used in operation in accordance with the principles of the present invention and may provide improved flushing capability.

The jet flush valve assembly 70 delivers fluid from its jet flush valve outlet 13 to the closed jet fluid path 1. The closed jet fluid path 1 comprises at least one jet channel (s). As shown herein, a single jet path (e.g., see arrows in FIG. 3 highlighting only one leg of the dual jet path of the assembly 10) or multiple channels may be used have. As shown in this embodiment, two such channels 38 are provided that originate from one inlet and couple at one outlet, while each channel is shown by the flow path shown in FIG. 3A And flows around the bowl from its lower side as well. A jet manifold may optionally be provided.

At least one rim valve is used.

A similar design as disclosed in British Patent Application GB 2 431 937 A or any future version of this design may be used as well, wherein the bowl is formed without a conventional hollow rim, To form a shelf or similar geometric feature within the contour of the bowl surface as shown, which allows it to enter the interior of the bowl at the position (s) displaced laterally from the rim inlet. Water is induced around the contoured inner surface. A standard rim channel having a rim inlet port that feeds into a rim channel formed by a conventional top rim and one or more rim outlet ports for introducing wash water into the interior region of the bowl may also be used in the embodiments described herein (See Figure 16 and Example 110). Such a rim may or may not be compressed, and may have various features as described in greater detail below with respect to embodiment 110. The rim features of embodiment (110) may be incorporated into the rimless version shown in Figures 1 to 13 or 28 without departing from the scope of the present invention.

The shelf width (s) fluctuates along the rim channel from the rim exit port. The contour has an inwardly extending portion 43 and an upper surface 47 on the shelf 27 that extends along the shelf but the contour does not allow a strong fluid flow from the rim inlet port the in having a slightly greater height than the depth (h ₁₎ and the shelf width (s ₁₎ for receiving areas so as to provide deeper shelves and shelf with a change in size, the rim illustrated in Figure 32 as (s ₂ and s ₃ ) maintains a suitably large shelf size at a substantially intermediate position (see FIG. 31) between the rear and front of the bowl as it continues along the shelf toward the front of the bowl. The height d is relatively constant, but the height h begins to extend toward the front of the bowl (see h ₂ and h ₃ ), while the shelf width decreases (see s ₂ and s ₃ ). Preferably, the depth in one embodiment herein is maintained between about 10 mm and about 30 mm. The height varies from about 35 mm to about 50 mm at the start of the flow from about 35 mm to about 50 mm at the midpoint between the rear and front of the bowl and from about 40 mm to about 55 mm at the front of the bowl. The shelf width is shown by s, where s is the lateral measurement taken along the tangent with the second radius of curvature R when the shelf is tapered down from the first radius of curvature r at the insertion edge of the shelf . The shelf is at an angle (alpha) with the tangent from the first radius. In this embodiment, the angle? Is 7 °, 5 °, 7 °, 22 ° and 31 °, respectively, as the shelf progresses along the path of FIGS. 30-34 as shown. As the angle increases, the radius increases and the shelf width (s) disappears with a downward slope as the shelf terminates.

In order to keep the siphon flush toilet assembly, such as assembly 10, in a primed water supply state, the initial steps may be performed as described above with respect to various other embodiments herein, including 110, 1010, 210, 310, Wherein a closed jet fluid path 1 having a jet channel 38 therein is provided from the outlet 13 of the jet flush valve 70 to the outlet of the jet 20, Once closed, the closed jet fluid path is able to be primed with fluids to prevent air from entering the closed jet fluid path before and after completion of the flush cycle do. The flush cycle is operated by any suitable actuator, such as a flush handle H. In one preferred embodiment, the pottery exterior and handles H are formed or provided from the materials herein to provide an antimicrobial surface. After initiating the flush cycle by a flush actuator, such as a handle, the handle has a portion (which may or may not be removable) operatively connected to the flush actuating bar 75.

The valves may have actuators that may all be open simultaneously (which may be done by a standard operating bar of the flush handle), or by using a flush operation handle such as that of FIG. 15 to provide a balanced approach, the weight of each flush valve cover / RTI > and / or < / RTI > As best shown in FIG. 15, the handle H is operatively connected to a pivot rod P having a rotatable mobile linkage RL. Any hinges, pin connections, washers or other rotating connectors may be used. The flush operating bar 75 has a balance point BP for the movable connection to the pivot rod P via the link device RL. A similar movable and rotatable linkage RL '(which may be identical to the rotatable linkage RL) connects the pivot load and its linkage RL to the flushing bar 75 at the balance point BP . The balance point is selected by design to operate as a flush valve to specifically and mechanically timing the opening of each valve when the handle H is pressed to actuate the flush cycle. When the handle H is pushed, the pivot rod P and the link device RL are urged upward at the end with the link device RL. Which is then pulled upward onto the actuating bar 75. It is possible to provide a bar 75 having a plurality of holes to provide a linkage for various balance points so that only one bar needs to be manufactured but can be used for various valve cover weights and flush timing patterns. While the flush actuation assembly is described in the context of a siphon flush toilet, it is understood that the flush actuation assembly may be used with any type of flush toilet seat including a wash-down toilet.

Assembly kit 1100 may be provided to improve operation and communication between handle H and one or more valves, as shown in Figs. 69-70 and Fig. Assembly kit 1100 may have a flush operation assembly 11144 that includes a pivot rod P, a flush actuating bar 1175 and a connector 11260. One end 11142 of the pivot rod P may be connected to a handle H located on the exterior of the tank or any other flush actuating mechanism while the opposite end 11143 of the pivot rod P Or may be connected to the connector 11260 using a rotatable connection. The pivot load P may be any standard or conventional pivot load, or it may be adjusted to the size and configuration of the tank. The position of the connecting element 11145 on the pivot rod P, which may be one or more opening (s), as shown in Figure 85, may be determined by the pivot rod, or the pivot rod As shown in FIG. Each manufacturer may have slightly different positions for connecting element 11145 along the length of pivot rod P, or the shape of pivot rod P itself may vary. Variations of the embodiment described herein for the connector 11260 may be used to compensate for the different positions of the connecting elements and thus a substantially arbitrary pivot rod P as well as other unconventional flush actuators It is contemplated that it is compatible with this embodiment. Variations of the embodiment of the connector described herein may also be applied to the handle H and pivot rod P with respect to the valve bodies 1131 and 1121 due to variations in handle and pivot rod configurations and / It may be useful to offset the deviation of the exact positioning. As such, the connector may ensure that a suitable positive lift is provided to the valve to trigger the desired operation.

85, the connector 11260A includes a connecting element 11145 in the pivot rod P at the first chain end 11264 creating the first rotatable connector 11153 and a second rotatable connector 11145 in the pivot rod P, Is shown as a chain C3 hooked to a connecting element 11261 on the flush actuating bar 1175 at a second chain end 11266 which creates a second chain end 11157. In each variation of the embodiment, the flush actuating bar 1175 and the pivot rod P are arranged in the same manner as the flush actuating bar < RTI ID = 0.0 > And the pivot load. Depending on the type of connector 11260 used, the connecting elements and connectors on the pivot rods may be varied to form a rotatable connection between these elements. Connector (11 260) has its longitudinal axis so as not to rotate in the circumferential flush operation bar 1175 is in relation to the pivot rod (P) axis (LA _c) may be rotated at a circumferential, but the pivot rod (P) has the axis (LA _c) ( LA _c ) (Fig. 85). In addition, the first rotatable connector 11153 between the pivot rod P and the connector 11260 should be rotatably positionable about the transverse axis TA _p of the pivot rod P. [ The second rotatable connector 11157 between the flush actuating bar 1175 and the connector 11260 should be rotatably positionable about the transverse axis TA _b of the flush actuating bar 1175. Preferably, the connector 11260 is an adjustable flush connector 11150, as shown in Figures 69 and 70 and described in more detail below. A further modification of this embodiment of the connector sufficient to provide rotational movement of the flush-actuated bar 1175 with respect to the pivot rod P is also an acceptable connector and is shown in Figs. 86 and 87. Fig.

86 and 87 illustrate additional variations of connectors 11260B and 11260C that provide rotational movement about its longitudinal axis LA _c . The rotational movement about the longitudinal axis LA _c of these variations of the connector is preferably provided by the ball and socket connector 11154 located along the length l _c of the connector at the longitudinal center point LC. A similar ball and socket connector 11154 is described below in more detail with respect to a variant of embodiment 1100 using the adjustable flush connector 11150 shown in FIG. 69 as an alternative embodiment for connector 11260 will be. 87, the spacer 11262 may be positioned between the ball and socket connector 11154 and the flush actuating bar 1175. As shown in Fig. Spacer 11262 may be included to provide easier rotation of flushing bar 1175 about its longitudinal axis, but this is not necessary for the connector to function properly.

In Figure 85 the first rotatable connector 11153 between the connector and pivot rod P as shown as chain 11260A is pivoted through opening 11158 where pin 11146 is positioned on connector 11260A It may be a hinged connection portion to be inserted. The transverse axis TA _p of the pivot rod, including the hooks inserted into the holes, the use of the protrusions on one element inserted into the opening on another element or the indentation, the ball and socket style joint, as well as any other known connection, It is understood that any connection between the connector 11260 and the pivot rod P that allows rotation of the pivot rod P may be used. Similar connections between the pivot rod P and the connector 11260 will be described in more detail below with respect to the adjustable flush connector 11150 in Figures 69-72.

Likewise, the second rotatable connector 11157 between the flush actuation bar 1175 and the connector 11260 may be the same or different from the connection used for the first rotatable connector 11153 between the connector and the pivot rod . As shown in Figs. 86 and 87, a hinge-shaped connecting portion 11268 in which the protrusion 11263 is integrally formed on the connectors 11260B and 11260C may be used. These protrusions 11263 may be inserted into the opening 11165 in the flush actuating bar 1175 and / or the side of the flush actuating bar through spring and / or torsional compression of the protrusions. Flush actuation bar 1175 may also rotate freely about the transverse axis TA _b of the flush actuating bar. Use with a second rotatable connector 11157, including the use of a pin through an opening in both elements, a hook inserted into the opening, a ball and a socket-type joint, as well as any other rotatable connection known or to be developed Additional types of connecting devices suitable for use are also contemplated. Similar connections between the connector 11260 and the flushing action bar 1175 will be described in more detail below with respect to the adjustable flush connector 11150 in Figures 69-72.

Although a number of exemplary variations of connectors 11260A-11260C are described herein, it is understood that any connector 11260 that provides rotational movement about the longitudinal axis LA _c may be used in the flush operation assembly. This rotational movement may cause the flush actuating bar to be in the proper position to actuate the valve assembly. Preferably, the connector 11260 may be an adjustable flush connector 11150, and the flush actuation assembly may be configured as described below.

Fig. 71 shows a front perspective view, and Fig. 72 shows a planar perspective view of the adjustable flush connector 11150 shown in Figs. 69 and 70. Fig. The preferred adjustable flush connector 11150 is configured to work with a variety of different pivot rods (P) and / or various different valve configurations. The configuration of the adjustable flush connector 11150 may have a connection element that is adjustable relative to each other in at least one direction. The adjustability of the configuration may include rotation about its longitudinal axis, rotation about its transverse axis, and / or movement along its longitudinal axis. Specific preferred structures for this purpose are described in more detail below. The adjustable flush connector 11150 preferably has a first section 11151, a second section 11152 and an adjustable connector 11156.

The first section 11151 preferably has a first rotatable connector 11153 configured to be connectable to the pivot rod (P). The configuration of the pivot rod P and the connection is such that when the end 11143 of the pivot rod P connected to the adjustable flush connector 11150 is moved upwards the adjustable flush connector 11150 also moves upward . The end 11143 of the pivot rod P connected to the adjustable flush connector 11150 may move upward when the handle H is pushed. The first rotatable connector 11153 may include a structure that causes the first rotatable connector to rotate at least about an axis transverse to the longitudinal centerline CL of the adjustable flush connector 11150, Pins, or hooks, ball and socket joints, snap fasteners, other hinged structures, or any other known connection to be inserted into the hole, one or more openings through which the hooks may be inserted.

The adjustable flush connector 11150 is preferably connected to the pivot rod P through the use of a first rotatable connector 11153. The opening 11158 in the first rotatable connector 11153 is preferably aligned with the opening in the end of the pivot rod 11143. Once the openings are aligned, the pin 11146 may be inserted through the opening and secured to the opposite side from the side from which the pin was originally inserted. The pin is preferably secured by inserting a cotter pin 11139 into the opening in the end of the pin that was inserted through the opening. Other ways of securing the pin are possible, including spring loaded pins, split pins, or other pins which preferably do not allow the pin 11146 to be removed from the opening. The method of inserting the pin 11146 through the opening to connect the adjustable flush connector 11150 to the pivot rod P is preferred but allows rotation of the adjustable flush connector 11150 with respect to the pivot rod P It is understood that any method of linking two elements may be used. The rotation of the first rotatable connector 11153 causes the longitudinal centerline CL of the adjustable flush connector 11150 to move vertically to the bottom of the tank as it is moved upwardly by the pivot rod P.

The second section 11152 of the adjustable flush connector 11150 may be connected to the first section 11151 of the adjustable flush connector 11150 through use of the ball and socket connector 11154. [ The ball and socket connector 11154 causes the second section 11152 to rotate about the longitudinal centerline CL of the adjustable flush connector 11150 relative to the first section 11151. [ The ball and socket connector 11154 also causes the second section 11152 to swing back and forth like a pendulum along any plane intersecting the longitudinal axis which is always perpendicular to the bottom of the tank, ) Is freed. The ball and socket connector 11154 includes sections 11151 and 11152 that cause the second section 11152 to rotate about its longitudinal axis relative to the first section 11151 and cause it to pivot back and forth along a plane intersecting the longitudinal axis of the second section, Lt; RTI ID = 0.0 > a < / RTI > However, only one of these ways, including hinged connection using a pin with an opening in the hook and loop or one or both sections 11151, 11152, allows for rotation of sections 11151, 11152, It is understood that any type of connector may also be used. It is further appreciated that the adjustable flush connector 11150 may be a single unit that has no possible movement or rotation between the first section 11151 and the second section 11152. [

Each of the first section and the second section may be made independently of a polymeric material or metal, and preferably they are different materials to prevent the matching portion from being constrained. It is preferred if the first section 11151, including the ball and socket connector 11154, is molded as a single unit from a polyester material. The second section 11152 is preferably formed of an acetal material. Other polymers, as well as other materials including various metals or alloys, are also contemplated for use in forming the first and / or second sections. Both the first section and the second section are preferably formed through thermoforming, such as an injection molding process. It is understood that other methods, including resin casting, compression molding, or three-dimensional printing, may also be used to create the first and second sections of the adjustable flush connector 11150. It is also understood that each section can be created using a different process. The length l _FC of the entire adjustable flush connector 11150 as measured along its longitudinal centerline CL is preferably from about 60 mm to about 130 mm. Length (l _1FC) of the first section (11 151) is preferably about 10 mm to about 50 mm, the length of the second section (11152) (l _2FC) is preferably about 50 mm to about 100 mm.

The first section 11151 preferably includes a socket element 11166 of the ball and socket connector 11154 and the second section 11152 preferably includes a ball element 11167 of the ball and socket connector 11154. [ . Both of socket 11166 and ball 11167 may have a generally spherical shape. The ball element 11167 of the second section 11152 is preferably inserted into the socket element 11166 of the first section 11151 and is dimensioned such that movement along the longitudinal axis with respect to the first section 11151 is kept to a minimum, Respectively. Ball 11167 should be dimensioned to move freely within socket 11166. [ The outer surface of the ball may be in contact with the inner surface of the socket, but if contact occurs, the friction created between the elements should be such that it does not interfere with the freedom of the ball 11167 to rotate within the socket 11166. [ However, the use of additional forces to rotate the element relative to each other due to friction is also acceptable.

The second section 11152 of the adjustable flush connector 11150 has an outer surface 11155 that may have optional threads 11159 to be configured to threadably engage the adjustable connector 11156. [ The preferred diameter D _2AC of the outer surface 11155, excluding the threads of the second section 11152, is from about 3 mm to about 12 mm. The thread 11159 on the surface 11155 of the adjustable flush connector 11150 may extend along the entire length of the second section 11152 except for the ball 11167 or other connector element. However, it is understood that only a portion of surface 11155 may be threaded. If only a portion of the surface 11155 has a thread 11159, at least about 20mm sufficient to allow the adjustable connector 11156 to engage the surface 11155 must be threaded. Additionally, it should be appreciated that surface 11155 need not include any threads.

Adjustable connector 11156 may have a longitudinal length (1 _AC ) of about 10 mm to about 30 mm. The diameter D _IAC of the inner surface of the adjustable connector 11156, as measured along the transverse centerline through the adjustable connector 11156, is from about 4 mm to about 15 mm. The diameter of the inner surface D _IAC should be compatible with the diameter of the outer surface D _2AC of the second section 11152 to enable the second section 11152 to be inserted into the adjustable connector 11156. The adjustable connector is preferably injection molded from a polyester resin or other polymer material. However, any method of manufacturing an adjustable connector including resin casting, compression molding, or three-dimensional printing may be used. In order to avoid binding of the components, the adjustable connector 11156 that mates with the flush-actuated bar 1175 and the adjustable flush connector 11150 should be a different material for each of these components.

The adjustable connector 11156 may have a mating thread on the inner surface that preferably forms the passageway through the adjustable connector 11156 such that the adjustable connector 11156 has an adjustable flush connector 0.0 > 11155 < / RTI > Threaded connection allows the adjustable connector 11156 to be longitudinally adjustable along the length of the second section 11152 and rotationally positionable about the longitudinal axis of the second section 11152. [ It is understood that although the use of a thread to connect the adjustable connector 11156 to the second section 11152 is a preferred embodiment, other ways of connecting the adjustable connector 11156 to the second section 11152 may be used do. This connection is also possible with the slidable connector having a clamping member, as well as the adjustable connector 11156 being longitudinally movable along the second section 11152 and rotationally positionable about the longitudinal axis of the second section 11152 Or any other connection that allows the user to make a connection. The second section 11152 may also be configured such that an individually adjustable connector 11156 is not required. This second section 11152 may include one or more protrusions or one or more openings located along the length of the second section for direct connection with the flush actuating bar. The position of the flushing action bar 1175 can be adjusted by selecting the position for direct connection using the opening or protrusion on the second section 11152 and the protrusion or opening on the flushing action bar 1175 by the length of the second section 11152 Will be adjustable accordingly. Additionally, the opening and / or angle of the projection in the second section 11152 may be varied about a longitudinal central axis such that the flush actuating bar may also be rotationally positionable about the longitudinal axis of the second section.

The adjustable connector 11156 preferably has a second rotatable connector 11157. The second rotatable connector 11157 is configured to connect the flush actuating bar 1175 to the adjustable connector 11156 at a balance point BP on the flush actuating bar 1175. [ The configuration of the second rotatable connector 11157 is such that the flush actuating bar 1175 is rotatable about the transverse line extending transversely from the side of the adjustable connector 11156. Certain preferred configurations are included below. The point of equilibrium BP preferably occurs in response to the elevation of the end 11143 of the pivot rod P connected to the handle H or the adjustable flush connector 11150, 1175 are elevated, the timing of the opening of each valve relative to the others is optimized. An embodiment regarding the timing optimization between the openings of the valve cover has been described above and is shown in Fig.

The preferred width w _FB of the flushing action bar 1175 is from about 2 mm to about 5 mm and the preferred height h _FB of the flushing bar 1175 is from about 5 mm to about 15 mm. The cross-section of flush-actuated bar 1175 may be substantially rectangular. However, cross-sections of any shape, including circular, oval, hexagonal, triangular, etc., can be used as understood by those of ordinary skill in the art based on this disclosure. Flush-actuated bar 1175 may be made from a polymeric material, metal or metal alloy, and is preferably injection molded using acetal. However, any manufacturing method, including resin casting, compression molding, or three-dimensional printing, may be used to manufacture the flush-operated bar.

Flush actuation bar 1175 preferably has two side arms 11177. The two side arms 11177 form and define the large opening 11164 in the bar body 11169 which is preferably positioned around the balance point BP of the flush actuating bar 1175. [ The large opening 11164 formed by the side arms 11177 may extend along the longitudinal axis of the flush actuating bar 1175. [ The large opening 11164 preferably has an oval cross section. However, any shape for a large opening 11164, including a circle or a rectangle, is contemplated. The side arms 11177 are preferably symmetrical about the longitudinal axis of the flush actuating bar 1175, but the symmetry of these elements is not essential. With respect to the preferred shape of the flushing action bar 1175, the side arms 11177 should be at least parallel to each other at one location along their length. It is contemplated that the size for the large opening 11164 may include an adjustable connector 11156 such that at least a portion of the entire adjustable flush connector 11150 may be inserted therethrough.

Two small openings 11165 are formed as part of the flush actuating bar 1175 and through the side arms 11177 forming a larger opening 11164, in the position where the two side arms 11177 are parallel to each other, It may extend in the lateral direction. The small aperture 11165 is preferably circular, but may have any shape that allows rotation of the connecting element, and at least the bottom of the small aperture 11165 should be substantially curved. The small aperture 11165 preferably corresponds to two projections 11163 extending from the side of the adjustable connector 11156, or arranged to receive these projections.

The adjustable connector 11156 includes two adjustable connectors 11156 each extending from one side of the adjustable connector 11156 to attach the flush actuating bar 1175 to the adjustable connector 11156 and create a second rotatable connector 11157. [ And includes a number of protrusions 11163. The two protrusions 11163 are preferably positioned toward the top of the adjustable connector 11156 and are preferably positioned on the same line extending laterally to the adjustable connector 11156. [ The projection 11163 preferably has a cylindrical shape. However, any cross-sectional shape such as an egg shape is considered. The cross-sectional shape is preferably rounded at least on the bottom edge so that the protrusion 11163 is rotatable within the small aperture 11165 in the flush-action bar 1175. [

As a method for forming the second rotatable connector 11157, the two protrusions 11163 include a flush operation bar 1175 which creates a connection rotatable about the projection 11163, which is a transverse axis of the flush actuating bar 1175, May be snap-engaged into the small aperture 11165 in the housing.

Two or more of the openings may extend across the second section at one or more different angles relative to each other. Two or more openings will allow the adjustable connector 11156 to be longitudinally movable and rotationally positionable. A similar arrangement may also be used to directly connect the flushing action bar 1175 to the second section 11152 of the adjustable flush connector 11150 without the use of the adjustable connector 11156 as described above. Other possible connections may include a threaded surface on the projection 11163. A conformably threaded arm surface having a smooth exterior surface may be used to removably secure the flush operation bar to the adjustable connector to create a second rotatable connector.

Alternative kits include a tank-to-bowl gasket tool as shown below in Figures 83 and 84, a flotation attachment as shown in Figures 88 to 90, or a multiple flush as shown in Figures 80 to 81, Valve assemblies < / RTI > Figure 69 shows the connection connecting action on handle H with valve opening. When the handle H is pushed, the pivot rod P vertically lifts the adjustable flush connector 11150, which then moves the flush actuating bar 1175 vertically at the balance point BP. Flush actuated bar 1175 preferably extends from first portion 11161 of bar 1175 to first valve assembly 1180 and second portion 11162 of bar 1175 to second valve assembly 1170 . The first valve assembly 1180 is preferably a rim valve assembly and the second valve assembly 1170 is preferably a jet valve assembly. Rim valve assembly 1180 and jet valve assembly 1170 are described herein in various embodiments of a priming water toilet and may be similar or identical to those described in the above embodiments as valves 80, have. To enable the use of flush-actuated bar 1175 with a wide range of connector styles used on chains C and C1 that connect flush-actuated bar 1175 to respective valve assemblies 1170 and 1180, One or more different types of connector pieces may be positioned on the first portion 11161 and / or the second portion 11162 of the flush actuation bar 1175, including other female fittings as shown in Figs. Likewise, hooks or other male fittings may also be included on one or both of the first portion 11161 and the second portion 11162. [

The position of the equilibrium point BP between the adjustable connector 11156 and the flushing action bar 1175 may affect the timing when each valve cover 1182 and 1173 is opened. The valve covers 1182 and 1173 may be set to open at the same time or by opening the rim valve cover 1182 completely before the jet valve cover 1173 begins to open, And may be set to optimize performance within a meal priming water jet toilet.

As the flush cycle is activated, the fluid flows through at least one rim valve, here through the rim flush valve assembly 1180 and through at least one jet flush valve, into the jet flush valve assembly 1170, Lt; / RTI > The configuration of the closed jet fluid path is like this and the timing of the flush cycle is optimized to maintain the closed jet fluid path with priming water after completion of the flush cycle. The flush mechanism and timing may be the same as the optimized performance described in the various embodiments (10, 110, 210, 310, 410, etc.) and the examples included herein.

In one embodiment of the method of the present disclosure, after actuating the flush cycle, the flush actuating bar is moved through at least one jet flush valve assembly at a flow rate sufficient to prevent air from entering the jet outlet and to create a siphon within the trap way To provide fluid. The flow rate then drops through the jet channel for about 1 second to about 5 seconds until the siphon is shut off and the flow is maintained at least until the jet exit port is covered.

The fluid is also preferably provided through at least one rim flush valve assembly during the flush cycle. When initially installed, the toilet may require an initial priming water supply by providing a sufficient flow rate through the jet flush valve assembly outlet to prevent air from entering the jet outlet port until the sump is filled with fluid as described above. The associated flow rates for carrying out these steps are outlined in different places herein. Preferably, the toilet assembly is capable of self priming water supply as described above and allows all or substantially all of the air to be released from the jet channel when the toilet is in a state where the jet channel has air. It is preferred that some traces of air, which preferably includes only up to about 100 ml in an embodiment such as the embodiment 10 disclosed herein, may enter the closed fluid jet path while still providing good operation, But acceptable performance may include a greater amount of air, but preferably less than about 500 ml to avoid degradation in performance. The specific amount may vary depending on the bowl geometry.

The toilet is typically in the primed water state, for example when the toilet is initially installed as described above, but other situations such as pipework or maintenance can also cause this situation. The user may, of course, manually intervene to priming the toilet assembly upon installation, or, as configured, the toilet can self priming water over one or more of the first multi-flush of the toilet without user intervention.

As shown in Figures 1 to 13 and 29 to 34 herein, the toilet is capable of releasing virtually all of the air to about three flushes, but more or less withdrawals can be made in the individual toilet geometry May be required. In order to allow the self priming water supply to complete, the two conditions: (1) the flow rate of the fluid through the jet flush valve needs to be greater than the flow rate of the fluid exiting the jet outlet port to provide sufficient energy to displace the air And (2) the route of escape from the upward or outflow through the jet flush valve assembly should be provided. This can be accomplished by modifying the jet channel and / or jet outlet port geometry and / or cross-sectional area and / or by modifying the flush valve to improve performance. It is therefore desirable to use a jet flush valve that can contribute to high energy and strong velocity flow into the closed jet fluid path through the jet channel. Suitable valves are described in U.S. Pat. No. 8,266,733 and pending U.S. Patent Application Publication No. 2014/0090158, all of which are incorporated herein by reference in their entirety for the purpose of describing a preferred embodiment of a valve having a streamlined valve body configuration and having a radial inlet and / Are incorporated herein by reference in their entirety. Other suitable flush valves are commercially available and are described elsewhere herein with respect to other embodiments of the toilet assembly described below in which the same flush valve may be used (as described below, See also FIGS. 35-68 of this disclosure for providing air venting). In addition to the gradually rising cover, the star pattern inner rib may also affect the speed of the air exhaust, as will be discussed further below.

As used herein, fluid communication means that one element of the assembly is structurally positioned to open for flow from other elements. The rim exit port (s) is in fluid communication with the interior region 137 of the bowl 130, wherein the interior region 137 is defined by the interior surface 136 of the bowl 130. The remainder of this assembly is similar to that in embodiment (10).

With regard to embodiment (10), the bowl assembly includes a directly fed jet (20) having the configuration of at least one jet channel (s) (38) as described above (Which may be provided to the user 110). The channel (s) extend between the jet inlet port 18 and the jet outlet port 42. At least one jet channel (38) has an inlet port (18) in fluid communication with the outlet opening (16) of the jet flush valve. The jet also has an elongated jet outlet port 42 for draining fluid from the jet channel 38 to the sump region 40. The sump region is in fluid communication with the trap way 44 or other toilet outlet conduit to drain the toilet bowl 30.

A fluid source (such as a flush water) may be used when the bowl is installed from an in-line flush-master type valve directly connected to the inlet port of the wall, such as in many industrial or commercial toilets. The assembly may optionally include a tank 60 as shown in Figs. 19 and 21. Fig. Preferably, the tank 60 receives the jet flush valve assembly 70 and the fluid from the outlet 13 of the at least one jet flush valve assembly 70 flows through the closed jet flow path 1 and the jet channels At least one opening 62 for receiving the rim flush valve assembly 80 and fluid from the outlet 81 of the rim flush valve assembly 30 to enter the rim exit port 28, At least one second opening 64 to allow entry into any optional rim manifold through the rim path to or from the rim manifold inlet opening.

The tank 60 should also include at least one fill valve 66 and optionally an overflow tube such as the overflow tube 91 shown in the embodiment associated with the rim flush valve. The tank 60 may be formed as a single open reservoir that accommodates both the jet flush valve and the rim flush valve in one region as shown in Fig. 19, or alternatively may be formed as described in the embodiment 1010 of Fig. 20 May also be configured as two separate reservoirs. The overflow tube is not a flow of jet flush fluid JF through a jet flush valve to remove any chance for air to enter the closed jet flow path 1 but a rim flush valve (In any manner associated with the valve body to be developed or to be developed) from the flow of rim flushing fluid (RF). The rim path may be kept open to the air without being affected by the connection of the invention to the overflow tube in the rim path.

The jet flush valve assembly 70 and the rim flush valve assembly 80 may include any standard commercially available flush valve assembly including any of a variety of designs known or to be developed in the pertinent art, Valve and flapper designs. The rim valve may likewise be an electrical, mechanical or computer operated type.

Examples of flush valve assemblies known in the related art that may be preferred for use in the embodiments herein may be found in U. S. Patent No. 8,266, 733 B2, incorporated herein by reference. The two valves can be opened and closed at the same time, or they can be opened and closed at different timings during the flush cycle to further optimize performance. In order to achieve a cleaner bowl with cleaner post-flush water, it is desirable to open the rim flush valve before opening the jet flush valve. In a preferred embodiment for 6.0 liters / flush, the rim flush valve is immediately opened at the start of the flush cycle and closed in a cycle from about 0.1 second to about 5 seconds, while the jet flush valve is closed from about 1 second It is opened at 5 seconds and closed at about 1.2 seconds to about 10 seconds.

In an ultra-low flush toilet with 3 liters / flush, the rim flush valve is immediately opened at the start of the flush cycle and closed in about 1 second to about 3 seconds into the cycle, while the jet flush valve is closed from about 0.1 second 3 seconds, and closed in about 1.2 seconds to about 3 seconds. In an embodiment of the present disclosure having a 54 mm diameter trapway, only about one liter of volume flowing from a fully primed closed jet channel is required to initiate the siphon, leading to the desired utility of the bowl wash and its function Enabling the application of the present invention to a flush toilet seat operating in a volume of less than or equal to 2 liters, depending on the amount of water dispensed.

Another embodiment for the dual flush toilet assembly immediately opens the double flush valve as a rim flush valve at the start of the flush cycle, which then triggers the jet flush valve to open after the rim double flush valve (single or double flush). The amount of water delivered to the rim for pre-siphon cleaning will be from about 1 liter / flush to about 5 liters / flush, preferably about 2 liters to about 4 liters / flush, and is passed through the jet flush valve to set the siphon The amount of water will be from about 1 liter / flush to about 5 liters / flush.

In the double valve assembly described above, each valve assembly was able to move relative to the other valve assembly. Due to the sufficient movement of the valve assembly, alignment with the flush actuating bar can be altered, resulting in a possible change in the timing of the valve opening and a possible reduction in performance of the flushing mechanism. Although the valve assembly has been described in the context of a siphon flush toilet, it will be appreciated by one of ordinary skill in the art based on this disclosure that the valve assembly may be used with any type of flush toilet seat, including wash- will be.

[ The first link 11210 and the second link 11220 are configured such that the first link 11210 interlocks with the second link 11220 to couple the first valve assembly 1180 with the second valve assembly 1170 do. The configurations of the first link 11210 and the second link 11220 refer to the shape of each element so that they are mutually lockable, and the shape of the link will be described in detail below. The optional linkage engagement device 11200 is preferably used to maintain a constant distance (d _V ) between the first valve assembly 1180 and the second valve assembly 1170. The connection provided by the linkage coupling device 11200 minimizes movement of the valve assembly relative to each other to maintain flush performance consistently.

The first link 11210 preferably extends from the edge 11211 of the rim valve body 1131 located closest to the jet valve assembly 1170. The first link 11210 preferably has a downward hook feature formed from two vertical sections 11212, 11213 and a horizontal section 11214. The first vertical section 11212 may be connected to or integral with the edge 11211 of the rim valve body 1131 and may extend upwardly from the valve body 1131 and extend upwardly from the upper portion of the first vertical section 11212 0.0 > 11215 < / RTI > The height ( _h1VS ) of the first vertical section 11212 is preferably about 10 mm to about 30 mm.

[ The distance between the rim valve assembly 1180 Ah jet valve assembly (1170) (d _V) may be variable, and may depend on the manufacturer of the toilet tank. The preferred distance between the rim of the valve assembly 1180 and a jet valve assembly (1170) _(V d) is from about 2 mm to about 10 mm. Using these distances, the preferred length l _HS for the horizontal section 11214 of the first link 11210 is about 4 mm to about 12 mm.

The second vertical section 11213 connects to the end of the horizontal section 11214 farthest from the rim valve body 1131 and extends downwardly toward the bottom of the tank and extends to the first vertical section 11212 It is substantially parallel. A second height (h _2VS) of the vertical section (11 213) is made to be sufficient to interlock with the second link (11 220). Second desired height for the vertical section (11213) (h _2VS) is from about 3 mm to about 8 mm. However, the height (h _2VS) depends on the height (h _UP) of the upward projection (11 222) of a first height in the vertical section _(1VS h), the second link (11 220) as well. The larger the height (h _UP) of the upward projection (11 222), a smaller height of the second vertical section (11 213) is required (h _2VS). However, the amount of the contact area of the second vertical section 11213 and the upward protrusion 11222 which are adjacent to each other may not be important. This contact area is preferably sufficient to maintain a link between the second link 11220 and the first link 11210.

The first link 11210 is described as having three sections 11212, 11213, and 11214. It is to be understood, however, that all three sections may be integrally formed together as a single piece, and may also be integrally formed with the valve element 1131.

The second link 11220 preferably has a generally rectangular shape with an upward projection 11222 when viewed from the front of the tank. In one embodiment, the second link 11220 has a horizontal element 11223 and an upward projection 11222. Horizontal element 11223 may be connected to or integral with edge 11221 of jet valve body 1121 and extend vertically from edge 11221 towards rim valve body 1131. [ The horizontal elements (11 223) may be set to the dimension extending into the rim valve assembly 1180 and a jet valve assembly 1170, substantially the entire distance (d _V) in between. The preferred length l _HE of horizontal element 11223 is from about 10 mm to about 20 mm. However, it is also possible to vary the distance _(V d) between the distance between the valve assembly (1180, 1170). The height h _HE of the horizontal element 11223 is preferably dimensioned such that the upper portion 11224 of the horizontal element 11223 is directly below the bottom portion 11217 of the second vertical section 11213 of the first link 11210. [ Respectively. The height h _HE of the horizontal element 11223 may vary from about 2 mm to about 27 mm, but the height h _UP of the upward protrusion 11222 is more important. The preferred height h _HE of the horizontal element 11223 corresponds to the desired size of the three sections 11212, 11213 and 11214 of the first link 11210 such that the first link 11210 and the second link 11220 is on each other, the distance (d _V) between the valve assembly (1180, 1170) to maintain relatively constant.

The preferred height of the upward projection (11222) (h _UP) is about 2 mm to is about 5 mm, a first vertical section 11212 of the horizontal element height (11223) (h _HE) and a first link (11 210) and the 2 depends on the height (h _{1VS, 2VS} h) of the vertical section (11 213). The preferred length l _UP of the upward protrusion 11222 is from about 1 mm to about 5 mm. This preferred length may be selected such that the upward protrusion 11222 is only fit within the hooked portion of the first link 11210 so that movement of the valve assemblies 1180, 1170 towards and away from each other is minimized .

Although the second link 11220 has been described as having two sections 11222 and 11223, the preferred second link 11220 is made from a single piece of material. Specifically, the second link 11220 may be made of a metal or polymer material, preferably a polymeric material that has been molded into the shape described above for the preferred embodiment. Preferably, the second link 11220 is formed integrally with the valve body 1121.

Both first link 11210 and second link 11220 may also be provided as separate items that may be installed on each valve assembly 1180, 1170 after the valve assembly is installed in the toilet. For this purpose, the first link 11210 and the second link 11220 are connected to a first link 11210 (not shown) to a strapping mechanism, a clamping mechanism, or the like, or to the first link valve body 1131 and the second link valve body 1121 And other connection devices that are capable of securing the second link 11220. In addition, the first link 11210 and the second link 11220 may be integrally formed, and the linkage device 11200 may have only one side. The linkage coupling device 11200 as a single piece may be provided with a coupling element, including a strap to be looped around the assembly, and / or a clamping device for connection to the sides of both valve assemblies. For example, a single rigid article can be attached to both valve assemblies. Such articles should be possible to 2 remains substantially constant as the distance (d _V) between the two valve assemblies (1180, 1170). It should also be noted that the valve bodies 1121, 1131 may also be formed as a single unit, eliminating the need for the linkage coupling device 11200.

As is preferred, both the first link 11210 and the second link 11220 are made from a rigid material. However, the flexible material may also be used for one or both of the links. The length l _UP may be increased so that the upward protrusion 11222 can be compressed to fit within the hooked portion of the first link 11210. [ If a flexible material is used for some or all of the elements described for the preferred first link 11210 and the preferred second link 11220, the amount of thickness and / And second valve assembly 1170 do not substantially move with respect to each other.

When viewing link coupling device 11200 from the top as in FIG. 79, the width W _LD of link coupling device 11200 extending transversely from the tank is visualized. The width of the first link 11210 and the width of the second link 11220 are preferably the same and a slight movement of one or both valve bodies 1121, 1131 in the direction transversely across the tank may cause mutual locking May be dimensioned so as not to be separated. The preferred width W _LD of the linkage device 11200 is from about 20 mm to about 40 mm. The width of the first link 11210 and the width of the second link 11220 are preferably the same, but either the width of the first link 11210 or the width of the second link 11220 may be larger, device (11200) will be understood that it should be possible to maintain a constant distance d between the _V of the valve assembly (1180, 1170). Both of the front side 11231 of the linkage device 11200 and the rear side 11232 of the linkage device 11200 may be open because it is possible to open one or both of the valve bodies 1121 and / And may allow for easier installation and removal.

A possible installation method for the multiple valve assembly 11205 according to this embodiment is to install one of the valve assemblies 1180 or 1170 in the tank and then install the second valve assembly 1180 or 1170 separately. Each valve assembly is preferably separately installed and secured to the bottom of the tank using conventional tank-to-bowl installation techniques. Additionally, a tank to bowl gasket kit as described below may be used. Each of the valve bodies 1121 and 1131 may be inserted through individual holes in the bottom of the tank. In the installation of the second valve assembly 1170, the first link 11210 and the second link 11220 are preferably mutually locked. By using this method, one valve assembly may be removed, repaired, or replaced without adjusting or removing other valve assemblies.

Another embodiment of multiple valve assembly 11205 including link coupling device 11200 may have a single multiple flush valve assembly 11206 as shown in Figs. 80 and 81. Fig. The single multiple flush valve assembly 11206 may include both the first valve assembly 1180 and the second valve assembly 1170 provided together as a single unit. The single multiple flush valve assembly 11206 may have a first link 11210 and a second link 11220 permanently attached to each other, as described in the previous embodiment. Additionally, the first and second valve bodies may be molded as a unitary structure. The attached linkage engagement device 11200 is preferably permanently attached to the first valve assembly 1180 and the second valve assembly 1170 to form a single multiple flush valve assembly 11206. Although the entire structure is permanently connected to the single multi-flush valve assembly 11206, the linkage device 11200 may be a separate element and may be a separate element before the installation in the toilet to create a single multiple flush valve assembly 11206, It may be permanently connected to the first valve element 1131 and the second valve element 1121.

Preferably, to create a single multiple valve assembly 11206, the two valve bodies 1121, 1131 and the connecting piece 11207 linking the two valve bodies are integrally formed with each other. The two valve bodies 1121 and 1131 may be as described in any one of the embodiments disclosed herein such as 10, 110, 210, 310, 410, 1010, 1110, Of the valve body. Preferably, a connecting piece 11207 of the same material may be molded together with the valve bodies 1121, 1131, so that the entire structure becomes a single piece. The connecting piece may also be permanently connected to the valve bodies 1121, 1131 after formation. The connecting piece 11207 is preferably of any size sufficient to maintain a constant distance between the valve bodies depending on the material used. Preferably, the connecting piece 11207 is made of a polymer material such as ABS resin and has a height (h _CP ) of about 2 mm to about 10 mm, a width (W _CP ) of about 10 mm to about 30 mm, mm to about 12 mm (1 _CP ). The length _lCP depends on the distance between the valve openings in the tank. The connecting piece 11207 preferably has a rectangular cross-section as taken transversely across the tank. Any shape for the cross section is contemplated, and the shape may be circular, oval, triangular, octagonal, or the like.

Another embodiment includes an installation method using a single multiple flush valve assembly 11206 in which the first valve assembly 1180 and the second valve assembly 1170 are permanently connected to one another. Additionally, this mounting method may be useful for installing two separate valve assemblies 1170, 1180 when the linkage device 11200 is mutually locked before the valve is installed in the tank. In an embodiment that includes a single multiple flush valve assembly 11206, both the first valve body 1131 and the interlocked second valve body 1121 are both installed in the tank at the same time and use a conventional tank- And may be fixed to the bottom of the tank. Additionally, a tank to bowl gasket kit as described below may be used. Each of the valve bodies 1121 and 1131 may be inserted through individual holes in the bottom of the tank. If not permanently connected, the individual valve assemblies 1170 and 1180 may be installed in a connected fashion. If so, the individual valve assemblies 1180, 1170 can be separated from each other and removed individually from the tank. However, individual removal would be difficult or impossible in a single multiple flush valve assembly 11206 where the first valve assembly 1170 and the second valve assembly 1180 are permanently attached to each other.

In an embodiment such as the toilet bowl assembly 110, a separate manifold for isolating fluid flow is introduced into the bowl assembly 110 from at least one flush valve assembly and is introduced into the jet 120 and into the rim 132, Deliver volume. This is because the fluid enters the bowl through the one-pot inlet, flows into the open single manifold, and then flows from the conventional toilet design, which flows into the jet 120 and downward into the rim 132 in an uncontrolled or gravity- Respectively. In this conventional design, the amount and nature of fluid flow to the rim or direct jet is difficult to control, and typically encourages jetting on the rim due to gravity and flow momentum. However, by isolating the fluid flow to the jets 120 and the fluid flow to the rim 132, the fluid flow is controlled and the jet and rim receive the desired fluid volume. In addition, it allows to maintain a closed jet flow path 101 including a primed water jet channel 138 and preferably a primed water jet manifold 112.

Any optional jet manifold 112 is preferably preformed into a pottery or other material of the toilet bowl, arranged in a stacked position, and / or juxtaposed to the rim manifold. The manifold may be juxtaposed to the same level but not completely. The jet manifold 112 may have a jet manifold outlet opening 116 for delivery of fluid to the jet inlet port 118. The rim manifold 122 includes a rim manifold 122 configured to receive fluid from the rim flush valve assembly 180 in variable amounts, for example, from about 0.1 liters to about 5.5 liters, preferably from about 0.5 liters to about 4.5 liters. Fold inlet opening 124. The folded- The rim manifold 122 also has a rim manifold outlet opening 126 for delivery of fluid to the rim inlet port 128. The flow of fluid through the jet 120 is directed downward along the jet channel (s) 138 and out of the jet exit port 142 and at a different time than the ingress of water through the rim channel 134 The sump region 140 and one of these flows may stop prior to the other, but through at least a portion of the flush cycle, the flow preferably occurs at the same time. These flow rates are selected to maximize flushing of the interior surface 137 of the toilet bowl 130 prior to draining the sump area 140.

In another embodiment, the rim channel 134 may be powered directly by line pressure from a typical residential or commercial pipeline. The opening and closing of the flow to the rim can be electronically controlled with a mechanical pilot valve similar to those currently used as a toilet fill valve or with a solenoid valve.

While the bowls of this disclosure, such as the bowls 30 and 130, may have a variety of configurations, most bowls are preformed to be generally round or oval or oval in shape when viewed transversely from the top of the bowl. In the embodiment described and illustrated herein, the bowl 30 generally has an oval shape. The bowl 130 has a rim 132 which is provided around its upper circumference to form a rim channel 134. The rim channel includes an inlet port 128 in fluid communication with the rim manifold outlet opening 126 (at a transition between the rim channel and manifold where the rim channel section becomes more uniform) and an interior region of the bowl assembly 110 136 and at least one rim exit port 129, preferably a plurality of such outlets. The bowl 130 is configured to allow the jet channel (s) to pass along the outer surface 135 of the bowl 130 or preferably within the wall of the bowl such that the jet outlet port 142 is in fluid communication with the lower portion 139 of the bowl 130 (Not shown).

In various embodiments of the present disclosure, such as the toilet 10, the jets 20 are connected to the sump zone 40, to the entrance to the geographed trapway way 44 and to the toilet exit O, And at least one jet channel 38 having a jet outlet port 42 configured to discharge fluid.

In the embodiment of FIG. 16, a portion of the flush water is directed through the rim channel 134 and passes through the channel 134 to disperse water over the entire surface of the bowl 30, which serves to clean the bowl during the flush cycle. Through the opening 129 located in the rim 132 that provides liquid communication between the inner regions of the bowl 130. [ The water flowing through the rim channel 134 may also be compressed in some embodiments of the present disclosure, exiting the external fluid source or exiting the rim exit port 129 as described above. Depending on the size of the outlet port, the geometry of the toilet bowl, and the flow rate, compression may not only clean the bowl but also cause a strong compressed stream of water to contribute to the siphon. The remainder of the flush water from the individual jet valve assembly 170 is directed to the jet 120.

The jets 20 and 120 and the at least one jet channel (s) 38 and 138 herein provide for a more energetic and rapid flow of flush water to the trapway inlets 44 and 144, Care should be taken to minimize bends and constrictions that may affect operation and to improve the performance of bulk excrement removal for non-jet and / or rim jet type bowls.

At least one jet channel 38 is designed to extend within the interior of the toilet bowl assembly 10 to pass around the outer surface of the toilet bowl 30 but is also generally designed to extend within the interior region wall 36 of the bowl 30, Is at least partially positioned within the space formed in the bottom or bottom bowl assembly body 10. Multiple jet channels of varying sizes may be used, for example two symmetrical channels on either side of the bowl 30 deliver a "dual feed" flow of fluid to the jet 20.

The jet outlet port 42 is configured to discharge fluid from the jet channel 38 into the sump region 40 in fluid communication with the trap way 44. The jet outlet port 42 preferably has a diameter of about 1.0 cm to about 10 cm, as measured in the longitudinal direction across the inside diameter of the jet channel 38, as shown in FIG. 23, , Preferably from about 1 cm to about 6 cm, and most preferably from about 1 cm to about 4 cm (H _jop ). Regardless of the height (H _jop ), the cross-sectional area of the jet exit port is about 2 cm ² to about 20 cm ² , more preferably about 4 cm ² to about 12 cm ² , most preferably about 5 cm ² and 8 cm ^{2 2} < / RTI > area. The height H _jop of the jet exit port 42 at the top surface 54 or at the top point is preferably _{greater than} the height H _j of the top surface 54 of the inlet 49 to the trap way 44, (X) below the sump region (56) and measured longitudinally through the sump region (40). The sealing depth x is preferably from about 1 cm to about 15 cm, more preferably from about 2 cm to about 12 cm, to assist in preventing passage of air into the jet channel 38 through the outlet port 42, cm, and most preferably from about 3 cm to about 9 cm. This distance is also preferably equal to or smaller than the minimum level of fluid in the sump region 40 to avoid breakage in the jet channel 38 and to prevent breakage of the jet flush valve assembly 70 or other flush valve before or after operation of the flush cycle Fluid must remain in the primed water supply in the jet channel 38 of the toilet bowl assembly 10. [

As described above, holding the primed water jet channel 38, i.e., the closed jet flow path 1, greatly reduces turbulence and flow resistance, improves toilet performance, and a smaller volume of water causes the siphon to start . The air in the jet channel 38 interferes with the flow of the flush water and restricts the flow of the jet 20. Moreover, if the air is not purged, it may exit through the jet exit port 42 and into the trapway way 44, which will retard the trap siphon and affect removal of the bowl 30 fluid and excreta.

It is also a desirable option to design the toilet assembly so that the rim is compressed during the flush cycle, in order to improve the cleaning function of the bowl in rim channel embodiments such as 110. The compression of the rim channel 134 is preferably accomplished by maintaining the relative cross-sectional area as in relation (I): < RTI ID = 0.0 >

A _rm > A _rip > A _rop <6 cm ² (I)

Where A _rm is the longitudinal cross-sectional area of the rim manifold 122, A _rip is the cross-sectional area of the rim inlet port 28, and A _rop is the total cross-sectional area of at least one rim outlet port 29. Preferably the cross sectional area A _jm of the jet manifold 112 is between about 20 cm ² and about 65 cm ² and the cross sectional area A _rm of the rim manifold 122 is between about 12 cm ² and about 50 cm ² . The cross-sectional area A _jm of the jet manifold 12 is measured at a distance of about 7.5 cm downstream from the center of the jet flush valve inlet opening 162. Similarly, the cross-sectional area A _rm of the rim manifold 122 is measured at a distance of about 7.5 cm downstream from the center of the rim flush valve inlet opening 164. Maintaining the desired geometry of the water channel within these parameters and otherwise avoiding constrictions or bends that affect performance can be achieved by providing a toilet bowl that maximizes the potential energy available through the gravity head of water available from the fluid source, Assembly 110, which becomes critical when a reduced water volume is used for the flush cycle. In addition, maintaining the geometry of the water channels within these parameters and avoiding constrictions and excessively small passages in the jets or traps allows for desirable compression of the rim and jet channels in the direct feed jet type toilet, Thereby maximizing performance in all of the cleaning. Preferably, the area of the rim exit port is intended to be the sum of all of the individual areas of each such exit port, since there are a plurality of rim exit ports, which may vary in size depending on the desired design. Similarly, if multiple jet flow channels 118 or multiple jet outlet / inlet ports are used, the jet channels 118 or any multiple ports 142 will be the sum of the respective areas of the jet channels or jet ports. In order to achieve the benefits of compression within the rim, the compression of the rim and jet channels in a compressed rim siphon toilet design and the compression of the compressed channels as described in U.S. Patent No. 8,316,475, It is desirable that the jet channel should not be made excessively small or shrunk so as to avoid clogging and poor performance when functioning with the limes.

The sump region 40 of the toilet bowl 30 of the embodiment 10 collects water, flush water and excreta for exhaust from the rim, jet channel 38. The sump region 40 is located in the bottom portion 39 of the bowl 30 and is located on the inner surface 36 of the bowl 30 extending longitudinally from the trap inlet end 46 to the trap outlet end 50 And the inlet end 46 has an opening 48 for receiving fluid from the jet exit port 42. The trap 41 is formed by a plurality of openings 48, The trap outlet end 50 has an opening 52 for fluid exiting the bowl to the inlet to the trap way 44. The jet trap 41 has a topmost point on the top surface 54 of the inlet to the trapway 44 and a topmost point on the top surface 54 of the jet outlet port 42 as shown in Figures 22, And a sealing depth (x) which is the distance between the top points.

The jet trap sealing depth x is preferably maintained at a distance of from about 1 cm to about 15 cm, more preferably from about 2 cm to about 12 cm, and most preferably from about 3 cm to about 9 cm, Lt; RTI ID = 0.0 &gt; siphon &lt; / RTI &gt; When the jet trap sealing depth x is sufficiently large this causes the trap way to block the siphon before the water level in the jet trap 41 can be pulled below the depth at which the seal portion of the jet channel 38 will break, Sets the buffer level of the fluid in the sump region 40 that helps to prevent the passage of air into the jet channel 38 and to keep the jet channel 38 in a full primed water supply. Conversely, in some embodiments, the jet trap sealing depth x may be zero or less than zero (when on the trap) and may be adjusted by adjusting the flow rate through the jet flush valve assembly 70, 1) can still be maintained.

At least a portion of the inner surface 36 of the sump region 40 is configured to increase the sealing depth x of the jet channel 38 and to reduce the likelihood of air entering the jet channel 38 during or after the flush cycle And an inclined portion 58 which may be inclined upward from the jet outlet port 42 toward the trap inlet. The sealing depth x can also be stretched by forming a jet channel 38 that temporarily dips down the floor of the sump prior to rising from the sump floor to the jet outlet port 42. The sealing depth x can also be increased by reducing the diameter of the jet exit port 42. [ Preferably, the height (H _jop ) of the jet outlet port 42 can be reduced to form a circular, oval or rectangular outlet, which increases the sealing depth (x) of the jet channel 38, Lt; RTI ID = 0.0 &gt; 20 &lt; / RTI &gt;

Although Figure 20 shows an alternative embodiment, generally referred to herein as assembly 1010, in all other respects the features of tank 1060 with the individual reservoirs as described below are the same and similar reference numerals Represent similar elements herein. The tank 1060 may include at least one jet reservoir 1068 and at least one rim reservoir 1072 and the jet reservoir 1068 may be configured for delivery of fluid to the jet manifold inlet opening 1062 And may include at least one jet flush valve assembly that may be identical to that of the jet fill valve 1090 and assembly 10 such as the rim reservoir 1072. The rim reservoir 1072 may include at least one May have at least one rim flush valve assembly that may be identical to the rim fill valve 1092 and assembly 110 configured for delivery. This may be a partial transverse section of the tank 1060 that allows the use of one filling valve, or the tank section may be a permanent preformed cast section of a tank into a plurality of reservoirs. If an overflow tube is optionally present in both the jet reservoir 1068 and the rim reservoir 1072, then the overflow tube will operate from the flow (RF ') of the rim flush fluid, not from the flow JF' .

23 and 24 illustrate another embodiment, generally referred to herein as assembly 210. [ However, in all other respects, the characteristics of the sump region in which the inclined wall is formed at the upward inclined or tapered position toward the entrance of the trapway 244 as described below is the same as that of the embodiment (10). The sump region wall 258 is designed to extend around and surround the sump region 240, as shown in FIGS. 23 and 24. The jet outlet port 242 is configured to allow fluid JF "from the jet channel 238 to flow into the bowl sump area 240 for merging with fluid entering the toilet bowl from the rim through at least one rim outlet port (not shown) The jet fluid flow (JF ") and the rim fluid flow (RF") are merged at that point (and with feces and other fluid, if present) And generally downwardly into the sump region 240 along the sump region 240 and into the sump region 240. At least a portion of the wall 258 may be in fluid communication with the jet channel 238 during or after the flush cycle, (X) of the jet channel 238 that helps prevent entry of the jet trap 241 into the jet trap 241. When the sealing depth x is sufficiently large, Jets The trapway way 244 blocks the siphon so that the passage of air into the jet channel 238 is prevented and the jet manifold 212 is pushed downwardly The buffer level of the fluid in the sump region 240 is set by assisting in ensuring that the fluid is maintained in the full priming water supply state.

Figs. 25-27 illustrate different embodiments for those of Figs. 16-24 generally referred to herein as an assembly 310. Fig. However, in all other respects, the features of at least one jet channel 338 below the bowl sump region 340, as described below, are the same as in embodiment (10). At least one jet channel 338 is designed to extend within the interior of the toilet bowl assembly 310 to be positioned behind the inner sphere wall 336 and the sump area wall at the rear of the bowl 330, 330 in the interior of the toilet bowl assembly 310 and below the sump area wall 358. At least one jet channel 338 passes below or below the sump region 340 and extends through the sump region wall 358 to position the jet exit port 342 directly opposite the inlet to the trapway 344. [ Lt; / RTI &gt; The advantage of this configuration is that it is possible for the design to gravity maintain the maximum jet fluid (JF "') capability, and that the level of fluid in the jet channel is inherently low, The at least one jet channel 338 will be more easily primed and maintained to be retained and to remove air within the jet channel 338. Because of the root setting of the jet channel 338 under the floor of the sump, Also increases the sealing depth x of the jet channel 338 beyond what can be achieved by the inclined sump floor embodiment as shown in Figures 25 and 24 so that the water level in the jet trap 341 The trap way intercepts the siphon before it can be pulled below the sealing depth x at which the sealing portion of the jet channel 338 will break and thereby allows the passage of air into the jet channel 338 And provides greater assurance of keeping the jet manifold 312 fully primed.

28 illustrates a different embodiment for those of Figs. 16-27 generally referred to herein as an assembly 410. Fig. However, in all other respects, the features of the upper periphery 433 around the upper main body of the bowl 430 are the same as described below. The rim 432 is configured to allow the fluid RF "" from the rim manifold to enter the bowl and wash down the excrement into the sump region 440 and enter the toilet bowl from the jet channel 438 and into the jet outlet port 442 And an upper peripheral portion 433 positioned around the interior of the upper main body of the bowl 430 to cooperate with the fluid that has been discharged through the bowl 430. The jet fluid flow JF "" and the rim fluid flow RF" " are merged at that point (and with feces and other fluids if present) and then along the bowl inner surface 436 for release through the sewage drain And generally downwardly into the trapway inlet 444 into the sump region 440 above the sump wall 458. When the sealing depth x is sufficiently large, the trap way intercepts the siphon before the water level in the jet trap 441 can be pulled below the depth at which the seal portion of the jet channel 438 will break, Which helps to prevent the passage of air into the sump region 440 and to keep the jet manifold in a full primed water supply state.

In another embodiment, a rimless version of the embodiment is shown in Fig. 28, wherein the flow of fluid enters the rim shelf from the rim inlet port at the rear of the distributor and in two opposite directions on the upper periphery 433, Passing around the inner surface of the bowl, thereby forming a cleaning action. In a preferred embodiment, the upper periphery 433 may be formed to guide the flush water downward as it flows around the main body of the bowl 430. This embodiment is similar to the assemblies of Figs. 1-13, but has a different rim shelf design.

In an embodiment of the preferred method of the present invention, after providing the toilet bowl assembly 10 as described by way of example herein by way of manufacture, the jets are pre-actuated and after actuation of the flush cycle, (70) to the fluid (JF). Although the method herein may be practiced on any embodiment of the disclosure, including assemblies 10, 1010, 110, 210, 310, 410, etc., for the sake of convenience, Will now be described with reference to the assembly 10 embodied in Figs. Similar portions of alternative embodiments may also be used when practicing the invention using other embodiments.

The priming water supply of the jet manifold 12, the jet inlet port 18 and the at least one jet channel 38 prior to the operation of the flush cycle opens the flapper or cover of the jet valve flush assembly 70, (Such as flush water) into the jet inlet port 18 and the at least one jet channel 38 during the installation of the toilet bowl assembly 10. This priming water supply will automatically occur with the first operation of the flush cycle. When the rim flush valve 80 and the jet flush valve 70 are closed the water will be held in the jet channel 38 and the jet manifold 12 and the atmosphere pressure on the surface of the water in the bowl 10 It will be held in place by force. If any small air pockets are retained in the at least one jet channel 38 or jet manifold 12 after the first flush, these air pockets will be vented at the next flush to yield a completely primed watered system .

After the initial priming water supply of the toilet bowl assembly of the present embodiment, the user will actuate the flush cycle. In standard conventional toilet bowl assemblies, flush valve assemblies such as those described herein and overflow tubes are provided for use. Both the flush valve cover and the bulb connected to the flush valve assembly are connected to the pivot arm. The pivot arm is attached to the top of the flush valve cover and includes a link for attachment to the chain that can be used to lower and raise the valve cover through operation of any standard valve actuator such as a flush handle and lever. In use, the pivot arm of the flush valve cover is attached to the overflow tube using a standard connection protruding from the overflow tube and opening and closing the inlet opening of the flush valve assembly.

When the flush cycle is disclosed or operated in the present invention, the flush valve cover opens on both the rim flush valve assembly and the jet flush valve assembly and allows fluid to pass through the at least one jet flush valve assembly 70 into the jet and rim do. By way of example, by using the embodiment of the flush actuating bar 75, 1175 described above, a time delay system, as is known or developed in the pertinent art to allow optimal flow through the toilet bowl assembly 10, Or open at the same time.

After operation of the flush cycle and after completion of the flush cycle, the jet inlet port 18 and the at least one jet channel 38 are configured such that (1) the depth of water in the reservoir feeding the jet flush valve is greater than the depth of the jet flush valve 70 Is not allowed to drop to the level of the inlet 71 to the jet flush valve 70 before being closed, and (2) the sealing portion of the jet channel 38 is not destroyed during or after the flush cycle . If all of these conditions are met, the closed jet flow path 1 including the jet channel 38 and the jet manifold 12 will be completely primed and maintained and ready for the next flush cycle.

The present invention will now be described with reference to the following non-limiting examples.

[ Conventional toilets required 79 to 82% of the flush water to be directed into the jet to achieve the desired hydraulic performance of the siphon. The toilet manufactured according to the present invention provided essentially equivalent hydraulic performance using less than 30% of the flush water induced in the jet, thereby allowing the remainder of the water to be used for significant improvement in bowl cleaning.

Various embodiments (10, 110, 1010, 210, 310, 410, etc.) of the present disclosure may each benefit from variations of the jet flush valve herein. Optional and unique features may be provided in the jet flush valve design described above to improve the operation of various embodiments. In use, when the toilet is clogged at all times, or for some other reason, the toilet needs plunging for a variety of plumbing reasons, such as back flushing upward through a closed jet path through a jet valve that releases clogging but is in a constant pre- . Backflow is not a problem in a normal toilet as the toilet is open to the atmosphere. In the present prime water feeding invention, backflow is a problem due to the weight of water and the existing columns of water in the jet channel. One way of modifying the jet flush valve of the present disclosure to prevent backflow is to provide a backflow prevention device in the jet flush valve. Such a device will now be described with respect to a jet flush valve similar to the jet flush valve 70 herein.

Although the flush valve design described above is highly effective against the backwash of water that can occur during plunging, additional levels of protection may be required in some embodiments. Intentionally blocking the priming water, i.e., introducing air into the closed jet channel and opening it into the atmosphere, significantly reduces the potential for backflow.

35-38 illustrate an embodiment of a jet flush valve referred to herein as a jet flush valve 570 having a flapper cover 573 and a backflow preventer mechanism 574 having a retention link arrangement. The cover 573 may be the same as the cover 15 of the valve 70 in the assembly 10. As shown, the cover 573 has a first front linkage mount 593 for attaching the retention link device. The linkage assembly within the backflow preventer mechanism 574 has a first forward (not shown) position with an attachment point P for chain C to connect to an actuator mechanism (such as in FIG. 15) And a link device arm 575. Such a chain may include a floating portion as described above.

The first linkage arm is connected to the second linkage arm 576 by a hinge pin such as pin 578, although other hinge connectors, pins, living hinges, molded pins, rivets or similar mechanisms may be used. Similarly, the linkage arm 576 is connected by a similar hinge connector to a third linkage arm 577 which is also pivotally mounted to the rear hinge mount 579. [ In use, when the flapper is raised, the countercurrent retaining link device rises freely, as shown, to form an angle of less than about 180 between the first and second link device arms when fully open.

When closed, the backflow protector is configured such that the first and second linkage arms will remain inactive on the chain C at point P (see Figs. 37 and 38 showing the valve in the closed position) Thereby preventing the flow from being re-pressed onto the flapper cover 573 by positioning the linkage arms so that they are more aligned in their joint region R at the more rigid position.

Another embodiment 670 of the jet flush valve is that the backflow preventer mechanism 674 is an active buoyancy poppet hat 694. Figures 39-43 illustrate the valve 670 in the closed position in which the poppet hat 694 is pressed against the area of the outlet 613 of the valve 670 in a sealing manner. The upward weight of the flushing water on the closed valve prevents water from entering the valve. Backflow can not enter the bottom of the jet flush valve when the valve is closed due to pressure from the poppet hat and the primed water-filled closed jet path as described above. If a solid poppet hat (not as buoyancy) is used, more force will be needed for operation and a spring or other tensioning mechanism can be used to connect the hat to the guide.

As shown in Figures 45-48, the jet flush valve 670 allows maximum flow through the valve body by the rise of the cover 673 when opened (as described above for valve 70) Or as with other flush actuators]. When the cover 673 is lifted, the flush water enters the previously primed valve, and the continuous downward flow pushes the poppet hat 694. The poppet hat 694 is preferably an elastomer or polymer, preferably partly sealable to the valve at the outlet 613. The poppet hat 694 is on the post 695 (which may be ribbed (or simply a round post) in the cross-sectional design, as best shown in FIG. 45).

The post has a top portion 699 opposite the location connected to the poppet hat 694 configured to have flange 6100. The flange acts as a stop for the poppet post guide ring 699 positioned centrally within the valve body under the ribbed structurally supported configuration. As shown best in FIG. 45, a "star" shape of rib 696 extending outwardly from central hub 697 is shown. The opening 698 extends through the hub to allow the poppet post to pass easily in the upward direction when the valve is in the closed position (see FIG. 43). When opened, the post will pass downward under flow pressure until the flange 6100 contacts the guide ring 699 at the fully extended position, so that the poppet hat 694 will not unnecessarily impede flow.

Another embodiment of the non-return jet flush valve 770 is shown in Figures 49-56. In this embodiment, the backflow prevention mechanism 774 is a hook 7101. [ The hook 7101 is fitted on the front end of the cover 7102 of the jet flush valve 770, which in a different embodiment is different from the other cover as described below. The hook 7101 has an extension hook arm 7103 that meets a catch 7104 located outside the jet valve body. The hook arm 7103 must have a predetermined clearance g therebetween and a facing surface 7105 of the latching portion 7104 but the gap must be as small as possible to provide an airtight closure to the counter flow, The hook is easily removed so that it does not become too small to swing around the latching portion 7104, and preferably the gap is about 1 mm to about 5 mm.

Except for the backflow preventer mechanism 774, the unique feature of the jet flush valve 770 is the cover 7102. The cover is not a simple lift-off flapper cover, but a "peel-off" cover. This design allows the opening of the jet valve towards the rear of the cover along the edge from the cover. The structure is formed to be flexible or partially flexible. Elastomers or other flexible polymers (such as flexible silicon or polyvinyl chloride) or similar materials that are permitted and graded for piping use may be applied for the flexible portion. The ability to peel the valve cover upwards along the edge 7105 of the front portion 7106 of the valve cover 7102 towards the rear portion 7107 by peeling allows the valve cover to be peeled off at a lower speed due to the presence of water below the cover, Lt; / RTI &gt; Applicants have found that the use of a flexible or semi-rigid cover to allow for delamination along the edge is advantageous in achieving good self priming watering conditions for the jet flush valve and the closed jet path. A rigid flapper cover, such as a hard cover with a standard disc seal, may provide more difficulty in self priming watering. By removing and releasing at low speed, valve 770 allows any trapped air to escape. It is preferred that at least about 50% of the cover 7102 is flexible within the front portion 7106 of the cover half to the rear toward the rear portion 7107 of the cover. The rear half of the cover need not be flexible.

In order to operate the peeling mechanism and lift the hook backflow preventer mechanism, the first chain C1 operates with the flushing mechanism of the toilet to raise the hook 7101 when the valve is opened, The front portion 7106 peels upward to rise. As it ascends, the hinged arms 7108 (which may be formed using any suitable hinge / hinge connection material and structure as described above with respect to embodiment 570) are bent upwardly. The hinged arm 7108 may be hinged to the optional cover plate 7110 (metal, polymer, or elastomer) using a hinge mount 7109 to assist in peeling the front portion 7106 of the cover 7102 upward . Any suitable flush actuator may be used and / or modified to connect to chain C1, C2. Once the C1 is lifted away from the front portion of the cover at the end portion 7105 so as to peel upward, the rear portion of the cover is raised. A separate suspension attachment portion, which may be a second chain (C2), which may have a floating portion thereon as described above, is provided. Other variations of the floating attachment portion for connecting the floating portion to the rear portion of the cover, including the floating portion assembly shown in Figures 88-90 and described in more detail below, may also be used. Strings, cords, ropes, stainless steel cables, rigid rods or wires may also be used with the floating portion as an alternative embodiment of the floating attachment.

The interior of the valve 770 also has a "star" shape using a structure formed with a rib 796 that links the body of the valve to a central hub 797, preferably through which the opening 798 extends. The flow can easily pass through the rib structure, but the structure helps support the weight of the flush fluid on the valve by extending radially across the body of the valve. The flapper is designed to facilitate the escape of air by having twice the force requirement for opening, thus assisting the support in operation, and also using molded baffles or ribs as shown. The number of ribs can affect the flow if too many ribs are present or if the ribs are molded in too large or improper way.

Figures 64-68 illustrate the same embodiment of a valve 770 having a selective overflow tube 791 disposed thereon. Overflow tube 791 includes an upper housing 769 for incorporating therein any of a variety of standard valves V as an alternative check for backflow through the jet valve and for allowing air to enter and exit . The valve can be manually rotated to the open position to block the priming water and allow plunging without backwash. Interception of priming water may also be desirable in other situations, such as before maintenance or repair. Any suitable valve, such as a ball valve, disc valve, or the like, may be incorporated therein. Valve V is schematically shown in a partial cross-sectional view of Fig. Housing 769 is optional, and other directional connection valves may be used. The valve is then manually reset by the user to the operating position, and the toilet can be returned to the primed water supply. Preferably, the valve is provided with a check valve that is automatically opened and held open when an amount of pressure experienced in the closed jet channel exceeds that experienced during a normal flush cycle such that air enters the channel and blocks the priming water . This check valve is then manually reset by the user to the operating position, and the toilet can be returned to the primed water supply. Most preferably, the check valve does not require manual intervention on a portion of the user and returns to the closed position after a delay of about 5 seconds to about 60 seconds. This can be accomplished electromechanically or mechanically, for example, by a flapper type valve with a liquid-hinged hinge.

58 and 59 show the same portion of the interior of the flush valve 870, except that the star shape of the support structure has eight ribs instead of four as shown in the valve 770 The same embodiment 870 is shown for a jet flush valve 770 having similar reference numerals. It should be appreciated by those skilled in the art that the number of such ribs and variations may be modified to provide varying degrees of structural support and to maximize and facilitate air release without unnecessarily restraining flow through the valve.

Figures 60-63 illustrate that the valve 570 is similar to the valve 570 except that instead of a single downward third linkage arm, the embodiment 970 includes a bridging structure 9111 having a larger width as it extends downwardly. A flush valve 970 with a backflow preventer mechanism 974, which is a similar retention link device arrangement. The bridging structure 9111 acts as a third linkage arm, but distributes the downward resistance towards the hinged mounting portion 9108. [ This hinged arm 9108 is attached at the hinge mount 9109 and operates to provide the cover 9102 with the ability to "peel" upward, as in embodiments 770 and 870. [ The forward portion of the backflow preventer mechanism 974 includes first and second hinged linkage arms 975, 976 similar to those of embodiment 570. The second linkage arm is then linked through a standard hinge connection to the top of the bridging structure 9111 which engages the rear portion of the hinged arm 9108 through the hinge structure 9112. [ The first linkage arm is connected to the front portion 9106 of the cover 9102 through a hinge mount 993. [ As opposed to embodiment 570, the cover 9102 may be mounted at a point P, although a chain (not shown) may be attached at point P as described in embodiment 570 to lift the front of cover 9102 It may be flexible as in the cover 7102 in the example 710 and thus peeled upwards. It is further contemplated that an additional chain may be used to lift the rear half of the cover 9102 in position 712 in the example 710 to raise the rear half of the cover 9102 at the location of the grommet 9113 or similar structure, It can also be used to maintain wealth. Grommet 9113 or similar structures may also be used to secure floating attachments, strings, cords, ropes, stainless steel cables, rigid rods, or wires as shown in Figs. 88-90.

Figures 69 and 70 illustrate another embodiment of a jet valve assembly 1170 similar to the jet valve assembly embodiments 770, 870, 970. This embodiment may also be used without a backflow prevention mechanism, or it may include a backflow prevention mechanism as shown in any one of the above embodiments (570, 670, 770, 870, 970, etc.). As shown in embodiment 770, the solution to overcome the additional force required to open the primed water jet valve is to provide a gradually opening valve wherein the section of the valve is "peeled" To allow predetermined water access to the valve, thereby balancing the pressure before the valve is fully opened. At least one valve assembly, preferably at least a jet valve assembly 1170, has a valve cover 1173 and valve body 1121 and is configured to "peel" open. It is also understood that multiple valve assemblies in a single tank comprising a rim valve assembly may have a similar configuration. It is also understood that although the valve assembly is described herein as being used with a siphon toilet, the valve assembly may also be used with any flush toilet, including a wash-down toilet.

Figures 73-75 illustrate one such embodiment of a valve cover 1173 having a seal portion 11170 and a rigid cover 11180 similar to the cover 7102 of the embodiment 770. [ The rigid cover 11180 is preferably bendable with the seal 11170 for gradual opening of the valve cover 1173. The rigid cover 11180 may preferably have a peel section 11182 and a lift section 11183 that are laterally separated from each other. The peeling section 11182 preferably has at least one hinged mounting portion 11108 configured to connect with the rising section 11183. The configuration of the connection between the hinge-coupled mounting portion 11108 and the riser section 11183 is preferably a rotatable connection. This configuration for the rotatable connection will be described in more detail below and is shown in Figs. 73 and 74.

Rigid cover 11180 operates similarly to cover plate 7110 of embodiment 770 described above. Preferably, the rear edge 11185 of the peeling section 11182 and the front edge 11186 of the ascent section 11183 are substantially parallel to each other and substantially parallel to each other in the central longitudinal direction defined by VP and VP ' And is also substantially perpendicular to the plane. There may be a transverse spacing TS between the edges 11185 and 11186. The distance d _TS from the rear edge 11185 of the peeling section 11182 to the front edge 11186 of the rising section 11183 is preferably 10 mm to 20 mm, . &Lt; / RTI &gt; It is possible that the peeling section 11182 is able to ascend from the valve body 1121 for a predetermined distance without moving the rising section 11183 and that each section has sufficient clearance to bend the sealing section 11170 without interfering with the process (D _TS ), as well as non-separation, is also considered.

The chain C1 may be used to connect the peeling section 11182 of the rigid cover 11180 to the flush operating bar 1175. [ The peeling section 11182 of the valve cover 1173 can rise from the valve element 1121 when the flush operation bar 1175 is lifted. The peeling section 11182 may be associated with the rising section 11183 via the hinged arm 11108. The hinged arms 11108 are preferably immovable at their connection with the peeling section 11182 and are configured to connect to the raised section 11183 by a rotatable connection. The hinged arm 11108 may be integrally formed with the peeling section 11182 during the forming process and preferably has two pegs 11115 extending from the outside of each of the hinged arms 11108. [ The peg 11115 is dimensioned to be inserted into the slot 11116 on a preferably cylindrical and hinged mounting portion 11109. It is understood that although two hinged arms 11108 are preferred and shown in the figures, one or more hinged arms 11108 may be used. The resiliently deformable support member 11117 may be positioned between the two preferred hinged arms 11108. The resiliently deformable support member 11117 is not required because the hinged arm 11108 may be dimensioned and molded to be resiliently deformable by itself.

The hinged arm 11108 preferably connects to the riser section 11183 via a hinge-coupled mounting portion 11109 by a connection rotatable about a line parallel to the front edge 11186 of the riser section 11183 . The hinged mounting portions 11109 each have a longitudinally extending slot 11116 preferably having an oval shape, but it is understood that any shape, such as a rectangle, circle, or hexagon, is possible. The peg 11115 on the hinged arm 11108 may be inserted into the slot 11116 through the use of resiliently deformable support members 11117. [ The oval shape causes peg 11115 to move rotationally, as well as longitudinally, within each of its slots 11116. This movement allows peeling section 11182 to optimally interact with riser section 11183. It is understood that any rotatable connection may be used for connection of hinged arm 11108 to riser section 11183 and longitudinal movement is not required. Possible rotatable connectors may include the use of any hinged joint, such as a protrusion on one element that snaps into an opening on the other element, or a pin inserted into an opening located within each element. Other types of connections are also contemplated that allow rotation about the same axis, including ball and socket joints.

As the peeling section 11182 continues to rise, the hinged arm 11108 preferably rotates about the connection with the hinged mounting portion 11109, thereby preventing the peeling section 11182 from moving for a short period of time, (11182) is lifted from the valve body (1121). Once the peeling section 11182 has been raised by a sufficient angle by the chain C1 and the flush actuating bar 1175 the hinged mounting portion 11109 preferably acts on the raised section 11183, The rising section 11183 of the valve body 11180 is opened to completely lift the entire valve cover 1173 from the valve body 1121. The floating portion F may also be attached to the valve cover 1173 through the use of a chain C2, a floating assembly 11270 described below, or other connecting device. The floating portion may provide buoyancy to reduce the force required to open the valve cover 1173 and / or to control the time of closing the valve through a drop in water level in the tank during flushing. Lower positioning of the floating portion along the chain may result in a later closing of the valve and an increase in flush volume.

An assembly kit 1100 having a flush operation assembly with a first valve assembly, a second valve assembly, and a second valve assembly having a floating attachment portion in the form of a floating assembly 11270 without any additional tools, 88. The floating assembly 11270 includes a floating portion F and a floating portion connector 11280 configured to connect the floating portion to the second valve assembly 1170. The floating attachment portion according to this modification may be used in place of the chain C2 to connect the floating portion to the second valve assembly. 89-90 illustrate an enlarged view of a second valve assembly 1170 that includes a flotation assembly 11270. Flap assembly 1170 includes a flap assembly 11270, Fig. 89 shows the valve cover 1173 in the closed position, and Fig. 90 shows the valve cover 1173 in the open position. The floating connector 11280 may be a rigid, or semi-rigid structure preferably made of a polymeric material. It is understood, however, that the floating connector may be constructed of any material having a suitable density so as not to interfere with the operation of the floating portion F in providing buoyancy to the valve cover 1173. [ The length l _FA of the floating connector may be varied to adjust the speed at which the valve cover fully opens. The length l _FA may range from about 4 cm to about 14 cm.

The floating connector 11280 has a first end 11271 and a second end 11272. The floating portion F is fixed on the first end portion 11271 of the floating portion connector 11280. [ The second end 11272 of the floating connector is connected to the second valve assembly 1170 through the use of a clip 11273 snap-engaged onto the raised bar 11274 located on the elevated section 11183 of the second valve assembly 1170. [ And is hingedly connected to the elevated section 11183 of the assembly 1170. The clip 11273 causes the suspension assembly 11270 to rotate about the longitudinal axis of the raised bar 11274. The longitudinal axis of the bar should be parallel to the axis through which the valve hinge 11275 rotates. Any pivotal connection, such as a pin, ball and socket joint inserted through a hole in one or both of the elements, or any other known rotational or hinged connection, may be used to connect the floating assembly to the raised section of the valve assembly , It is understood that the rotary connection is rotatable about an axis parallel to the axis through which the valve hinge (s) 11275 rotate.

The first end 11271 of the floating connector may include a latch 11276 for holding the floating portion F. [ The latch 11276 is somewhat resiliently deformable such that the force that attempts to return the latch to its rest position when the suspending portion is inserted into the opening ensures that the floating portion F is kept in place by friction. For use with a standard flush, the opening of the latch at its minimum height (h _SC ) is preferably about 0 cm to about 4 cm high at rest and about 1 cm to about 5 cm cm (the height of the floating portion). The height of the maximum height of the opening of the latch (h _TC ) is about 2 cm to about 6 cm for both when paused and when the floating portion is inserted therein. The bottom of the latch may have a flat platform 11277 having a shape similar to the bottom of the flotation and the top 11278 of the latch may be curved so that the entire first end 11271 is shaped similarly to the cotter pin. The resiliently deformable nature of the latch permits the use of a variety of different floating portions, so that the buoyancy of the valve cover is adjustable and, if necessary, permits easy replacement of the floating portion.

Once the peeling section is raised to the point where the upward force is increased on the rising section, the floating section provides aiding that a small force is required to open the rising section fully. When the valve is open, the connection between the second end 11272 of the float assembly 11270 and the riser section 11183 causes the floating section F to remain in a vertical position through the opening of the valve cover. One or more stops 11279 can be positioned on either side of the clip 11273 such that when the level drops below the level of the floating portion F the float assembly 11270 is fully lowered You will not. It will be understood by those skilled in the art based on this disclosure that although the stop is not essential for proper functioning of the float, these stops may prevent the float assembly from interfering with the operation of other parts of the valve assembly It will be possible.

Although the second or jet valve assembly has been described as having a floating attachment portion, it should be appreciated that the jet valve assembly and / or the rim valve assembly may include a floating attachment portion and that either or both valve assemblies may behave in a similar manner I understand.

Figures 76 and 77 illustrate a seal that may be used with a rigid cover to move with the rigid cover 11180 to prevent liquid from entering the jet inlet when not required and to gradually open the valve cover 1173. [ 0.0 &gt; 11170 &lt; / RTI &gt; Sealing portion 11170 may have sealing surface 11171 and locking surface 11172. [ The locking surface 11172 may include a plurality of locking lugs 11173 that may help secure the sealing portion 11170 to the rigid cover 11180, as shown in Figures 73-75. Seal 11170 is preferably positioned in face-to-face relationship with peel-away section 11182 and riser section 11183. The seal is preferably attached to the rigid cover 11180 either through the use of a plurality of locking lugs 11173 alone or with an adhesive or other fixing method. The locking lugs 11173 may serve as additional features to help prevent the force of the liquid flow from pulling the seal 11170 out of the rigid cover 11180. [ It will be appreciated that although use of the locking lug 11173 may be preferred, use of only an adhesive or other fastening method is also possible.

The lock lug 11173 may assist the peeling of the valve cover 1173. The arrangement of the locking lugs 11173 across the seal 11170 may be such that one or more of the locking lugs 11173 are located within the peeling section 11182 and one or more of the locking lugs 11173 May be located within riser section 11183. As the peeling section 11182 is raised, a force may be applied to the seal portion 11170 in a direction opposite to the movement, this force will pull the seal portion 11170 away from the rigid cover 11180, So as to keep the valve closed. The delay may affect the timing between the opening of the rim valve and the opening of the jet valve and / or may reduce the benefit of opening the peeling section prior to the riser section. The locking lug 11173 preferably provides a counter force against the liquid on the seal 11170, which must be sufficient to raise it from the valve body 1121 and to maintain the proper timing of opening of the valve.

A plurality of locking lugs 11173 may be arranged around the locking surface 11172 and may be positioned to engage a plurality of corresponding openings 11188 in the rigid cover 11180. The preferred arrangement may, for example, include three rows of lock lugs 11173, wherein one or more lock lugs (s) 11173 are located in each row. Preferably, the first row 11174 may have at least one locking lug (s) 11173 configured to connect to the peeling section 11182 and the second row 11175 may have at least one locking lug And the third row 11176 may have at least one locking lug (s) 11173 configured to connect to the rear of the riser section 11183 . The configuration of the connection of the lugs 11173 is such that the size and shape of each lug 11173 is relatively easily inserted through the opening and more difficult to remove from the opening. The configuration of the connection between the lock lug and each of the peel and lift sections may depend on the position and shape of the particular lock lug. Certain desirable features of the configuration will be described in greater detail below.

The specific position of each locking lug is dependent on the size and / or shape of the valve cover 1173. The rows 11174 through 11176 may be located at various distances from the point CP located on the front edge of the seal portion 11170 on the central vertical longitudinal plane VP, VP 'through the valve cover 1173 . Preferably, for a standard valve cover size, the first row 11174 may be located at a distance d _IR from about 5 mm to about 15 mm from the point CP, (D _2R ) from about 40 mm to about 60 mm from the point CP and a third row 11176 is located at a distance d _3R from about 60 mm to about 80 mm from point CP . This configuration allows sufficient securing of the sealing portion 11170 to the rigid cover 11180 and also allows the peeling section 11182 and the riser section 11183 to open at different times.

Other configurations for a plurality of locking lugs 11173 are also contemplated. For example, only a single row of lock lugs may be used, where the rows are preferably located at about 5 mm to about 30 mm from point CP. This position allows the lug to secure the seal to the rigid cover as the peel section is raised. A single row may also be located at about 30 mm to about 90 mm from point CP. The use of two rows of lock lugs is understood wherein one row is located at about 5 mm to about 30 mm from point CP and the second row is located at about 35 mm to about 90 mm from point CP . Generally, with the use of zero, one, or more rows located at about 35 mm to about 90 mm from point CP in any combination, including the use of zero rows of lugs, One, or more rows located from about 5 mm to about 30 mm from the point of view CP. The position of the lug may also depend on the size and / or shape of the valve cover 1173. Preferably, at least one row is located within the peeling section 11182, and at least one row is located within the riser section 11183.

The preferred shape for each locking lug 11173 may include a head 11190 and a neck 11191. [ The head 11190 is preferably slightly larger than the neck 11191 so that when the head 11190 is inserted into the corresponding opening 11188 in the rigid cover 11180 the sealing portion 11170 is attached to the rigid cover 11180 Thereby being locked adjacently. Head 11190 is preferably conical with generally rounded top surface, and neck 11191 preferably has a generally cylindrical shape.
