[0003] The present invention relates to the field of gravity toilet bowls for the removal of humans and other excrement. The present invention further relates to the field of toilet bowls operated by a primed water delivery system to improve performance.

[0004] Toilet bowls for removing waste, such as human excrement, are well known. Gravity toilets generally have two main components: a tank and a bowl. Tanks and bowls are separate parts that are combined together to form a toilet system (commonly referred to as a two-piece toilet), or combined into one integrated unit (typically referred to as a one-piece toilet). It can be).

[0005] A tank, normally located on the back of the bowl, initiates the flushing of excrement from the bowl to the sewer and houses the water used to refill the bowl with fresh water. When the user wants to flush the toilet bowl, the user pushes down the flush lever on the outside of the tank, which is connected to the movable chain or lever inside the tank. When the flush lever is pressed, it lifts the flush valve inside the tank and moves a chain or lever that acts to open, flushing water from the tank into the bowl, thereby initiating toilet flushing.

[0006] There are three general purposes that must be fulfilled in the wash cycle. The first purpose is the removal of solids and other excrement into drains. The second purpose is to clean the bowl to remove solid or liquid excrement that has accumulated or adhered to the surface of the bowl, and the third purpose is to keep the bowl relatively clean water before the next use. The amount of water before washing in the bowl is replaced so that it remains inside. The second requirement, bowl cleaning, is usually accomplished with a hollow rim extending over the upper circumference of the toilet bowl. Part or all of the flush water is directed through the rim channel and flows through the openings located therein, sprinkling water over the entire surface of the bowl to perform the required wash. A third requirement is to refill the bowl with clean water, thereby restoring the sealing depth against backflow of sewage gas and preparing for the next use and wash.

[0007] Gravity toilets can be divided into two general categories: wash-off and siphon. In the wash-off type toilet, the water level in the bowl of the toilet is always relatively constant. When the wash cycle begins, water flows out of the tank and overflows into the bowl. This causes a rapid rise in water level, and excess water overflows onto the trapway weir, carrying liquid and solid excrement with it. At the end of the wash cycle, the water level in the bowl naturally returns to the equilibrium water level determined by the height of the weir.

[0008] In siphon toilets, the trapway and other hydraulic channels are designed so that the siphon is initiated within the trapway after water has been added to the bowl. The siphon tube itself is an inverted U-shaped tube that draws water from the toilet bowl into the sewage tube. When the flush cycle begins, water flows into the toilet bowl and overflows onto the weir in the trapway faster than it can exit the outlet to the sewer. Eventually, sufficient air is removed from the lower leg of the trapway to initiate the siphon, which in turn draws the remaining water out of the bowl. As a result, the water level in the bowl when the siphon is interrupted is well below the level of the weir, and at the end of the siphon wash cycle, the bowl of the toilet bowl is refilled with water to protect the original water level and the backflow of gas in the sewage. A separate mechanism needs to be provided to reestablish the "sewer".

[0009] Siphon and wash-off toilets have unique advantages and disadvantages. Siphon toilets tend to have smaller trapways due to the requirement that most of the air must be removed from the lower leg of the trapway in order to initiate a siphon, which can result in clogging. Wash-off toilets can function with large trapways, but generally the 100: 1 dilution level required by plumbing regulations in most countries (ie, 99% of the pre-wash water volume in the bowl, is It is necessary to reduce the amount of pre-wash water in the bowl to achieve (which must be removed from the bowl during the wash cycle and replaced with fresh water). This small pre-wash amount appears as a small "water spot". The water spot, or surface area, of the pre-wash water in the bowl plays an important role in maintaining the cleanliness of the toilet bowl. Large water spots increase the probability that excrement will come into contact with water before it comes into contact with the ceramic surface of the toilet bowl. This reduces the buildup of emissions on the ceramic surface, thereby making it easier to self-clean the toilet bowl with a flush cycle. Wash-off toilets with small water spots therefore often require manual cleaning of the bowl after use.

[0010] The siphon toilet has the advantage of being able to function with a larger amount of pre-wash water and a larger water spot in the bowl. This is possible because the siphon action pulls most of the pre-wash water volume out of the bowl at the end of the wash cycle. When the tank is refilled, a portion of the refill water is directed into the bowl and the pre-wash water level can be returned to its original water level. In this way, the 100: 1 dilution level required by many plumbing rules is achieved even when the starting amount of water in the bowl is significantly higher than the flush water coming out of the tank. In the North American market, siphon toilets have been widely and generally accepted and are now regarded as the standard, generally accepted form of toilet bowls. Wash-off toilets are still more accepted and popular in the European market, while both versions are common in the Asian market.

[0011] Gravity siphon toilets can be further divided into three general categories, depending on the design of the penstock used to achieve the wash action. These categories are non-squirting, rim-squirting, and direct-squirting.

[0012] In non-squirting bowls, all of the flush water exits the tank into the bowl inlet area, flows through the main manifold and into the rim channel. Water is sprinkled over the circumference of the bowl through a series of holes positioned under the rim. Some of the holes can be designed to be larger in size to allow more water to flow into the bowl. A relatively high flow rate is required to displace sufficient air in the lower leg and allow water to spill onto the trapway weir with sufficient speed to initiate a siphon. Non-squirting bowls usually have good enough performance for bowl washing and pre-washing water replacement, but relatively poor performance for mass removal. The water supply to the trapway is inadequate and turbulent, which fills the lower leg of the trapway well and makes it more difficult to start a strong siphon. As a result, trapways for non-squirting toilets typically have smaller diameters and include bends and constrictions designed to impede the flow of water. In the absence of smaller sizes, bends, and stenosis, strong siphons are not achieved. Unfortunately, the smaller sizes, bends, and stenosis result in poor performance, frequent clogging, and extremely unsatisfactory conditions for the end user in terms of removing large amounts of excrement.

[0013] Toilet bowl designers and technicians have improved the removal of large amounts of excrement in siphon-type toilet bowls by incorporating a "siphon ejector". In a rim-spouting toilet bowl, flush water exits the tank, flows through the toilet inlet area, flows through the main manifold and enters the rim channel. A portion of the water is sprinkled over the circumference of the bowl through a series of holes positioned under the rim. The rest of the water flows through the ejection channel located in front of the rim. This ejection channel connects the rim channel to an ejection opening positioned within the bowl's reservoir. The ejection opening is sized and positioned to direct a strong stream of water directly to the trapway opening. When water flows through the ejection opening, it works to fill the trapway more efficiently and quickly than can be achieved in a non-spouting bowl. This more vigorous and quick flow of water to the trapway allows the toilet bowl to be designed with a larger trapway diameter and less bends and constrictions, which is compared to non-squirting bowls. Improves performance in removing large amounts of excrement. Although less water flows out of the rim of the rim ejector, the bowl washer function is generally acceptable as the water flowing through the rim channel is pressurized by the upstream flow of water from the tank. be. This allows water to exit the rim hole with higher energy and do a more effective job of cleaning the bowl.

[0014] Rim ejection bowls are generally superior to non-squirting bowls, but long passages where water must travel through the rim to the ejection opening dissipate and waste available energy. .. Direct ejection bowls can make improvements in this concept and provide better performance for mass removal of excrement. In a direct-spout bowl, flush water exits the tank, flows through the bowl inlet, and through the main manifold. At this point, the water flows through the two parts, the rim inlet port and the rim channel, the part with the main purpose of achieving the desired bowl wash, and the spout inlet port, through the main manifold. It is divided into the part leading to the "direct ejection channel" that connects to the ejection opening in the basin of the toilet bowl. Direct eruption channels can take various forms, sometimes unidirectional or "double-fed" around one side of the toilet bowl, where symmetrical channels travel on both sides. Then go down and connect the manifold to the ejection opening. As with the rim ejection bowl, the ejection opening is sized and positioned to direct a strong stream of water directly to the trapway opening. When water flows through the spout opening, it works to fill the trapway more efficiently and quickly than can be achieved in a non-spout bowl or a rim spout bowl. This more vigorous, swift flow of water to the trapway allows the toilet bowl to be designed with an even larger trapway diameter and minimal bends and constrictions, which is non-squirting. Improves performance in removing large amounts of excrement compared to bowls and rim ejection bowls.

[0015] Direct-fed squirt bowls are currently a large part of the state-of-the-art technology for mass removal of excrement, but there are still major areas for improving toilet performance. Government officials continue to demand reductions in the amount of water used by urban water users. Of particular interest in recent years has been to reduce the water demand required by the activation of the toilet flushing action. To exemplify this point, the amount of water used in the toilet bowl in each wash varies from 7 gallons / 1 wash (before the 1950s) to 5.5 gallons / 1 wash (end of the 1960s), 3 It has been gradually reduced until 1.5 gallons / 1 wash (1980s). The National Energy Policy Act of 1995 now requires that toilet bowls sold in the United States can only use 1.6 gallons per wash (6 liters per wash). Recently, a legislation was passed in California requiring that water usage be further reduced to 1.28 gallons / wash. The 1.6 gallon / 1 flush toilets currently described and commercially available in the patent literature lose the ability to consistently siphon when reduced to these lower levels of water consumption. Therefore, manufacturers are and will be forced to reduce the diameter of the trapway at the expense of performance without the development of improved technology and toilet design.

[0016] Several inventions have been aimed at improving the performance of siphon toilet bowls through optimization of the direct ejection concept. For example, in US Pat. No. 5,918,325, the performance of siphon toilets is improved by improving the shape of the trapway. In US Pat. No. 6,715,162, performance is improved using a flush valve with a semi-curved inlet and an asymmetric flow of water into the bowl.

[0017] US Pat. No. 8,316,475B2 is a pressurized rim that allows enhanced washout and appropriate siphon for the use of low volumes of water that meet current environmental water use standards. And demonstrates the configuration of direct feed eruptions.

[0018] U.S. Patent Application Publication No. 2012/0198610A1 is a control element within the main manifold that divides the flow of flush water from the tank inlet into the toilet bowl inlet into the inlet port of the rim and into the inlet port of the direct supply ejector. The high performance toilet bowl achieved by is also shown. U.S. Pat. No. 2,122,834 shows a toilet bowl with an air manifold and a hydraulic manifold for introducing air into the toilet bowl flush cycle to terminate the siphon action and prevent backflow into the system. There is. Other inventions attempt to address the performance between the rim and the spout by dividing the toilet tank into separate sections. See U.S. Pat. No. 1,939,118.

[0019] Minimization of turbulence and flow restrictions within the internal channels of the toilet bowl is of paramount importance when the wash volume is extruded below about 6.0 liters. One of the most important factors in minimizing turbulence and restrictions on flow is the management of air occupying the rim and ejection channels prior to the start of the wash cycle. If the air cannot escape from the system before the flush water rushes in, the air occupies the space in the channel and continues to limit the flow. US Pat. No. 5,918,325 includes an air ejection means, that is, a toilet bowl with a ejection channel that includes a passage connecting the ejection channel to the rim and allows air to escape from the ejection channel into the rim during flushing. Is explained. US Patent Application Publication No. 2012/0198610A1 also discloses a toilet bowl with a downstream communication port that allows air and / or water to pass between the ejection channel and the rim channel.

[0020] The need to further improve siphon toilet performance and specifically manage the pre-wash air that occupies the ejection channel remains in the art. There is also a need for a toilet bowl that remedies the shortcomings noted above in prior art toilet bowls by reducing clogging and enabling significantly improved cleaning during the flushing action without sacrificing flushing performance. Exists in the technical field. Such toilet bowls should also still meet water conservation standards and government guidelines, while forming sufficient siphons for low water consumption to match the geometry of various trapways.

Unless there is a counter-wording that points to similar features of the invention, thereby describing an alternative configuration of a particular feature, one of ordinary skill in the art will be one such feature based on this disclosure and its accompanying drawings. It will be appreciated that the description of should be applicable to other embodiments that explain similar features.

[0164] In the present invention, preferably, a fluid introduced into the bowl assembly to deliver different amounts of fluid from the ejection flush valve and the rim valve, such as a rim flush valve, through a separate closed ejection fluid path. A siphon flush toilet assembly is realized that is capable of maintaining a closed priming fluid passage that is primed, including the squirt channel, by isolating the flow. It operates on an air-filled ejection channel and offers more powerful performance compared to standard gravity flush siphon toilets that must expel air to minimize turbulence and flow limits.

[0165] The toilet bowl assembly of the present invention has a closed ejection fluid path, including an ejection channel within the toilet assembly outside the bowl. The ejection channel is a bowl-molded geometry, including an optional ejection manifold, as long as the closed ejection fluid path accepts fluid from the ejection valve outlet into the ejection inlet port and through the ejection channel to the ejection outlet port. Depending on the geometry, it may have various configurations and extension regions, additional ports or side channels, and the like. The closed squirt fluid path keeps the squirt channel permanently primed, effectively isolating it and thereby helping prevent air from entering the squirt channel. .. It (1) isolates the ejection channel from the rim flow or other passages open to the atmosphere, and (2) closes the ejection channel flush valve before the water level in the tank drops to the level of the flush valve opening. Thereby, (3) assisting to prevent the air flow from entering the ejection channel and any other ejection path, region, or optional ejection manifold when used, which in one embodiment is air. By including establishing a sealing depth in the ejection trap in the reservoir area to help block the entry into the ejection channel outlet, and / or (4) the water level in the ejection trap, It is accomplished by constructing and operating the assembly to ensure that the air travels backwards and does not descend to a level that can enter the ejection channel.

[0166] In general, the ratio of fluid volume to the rim to fluid volume to the spout also affects the performance of the toilet bowl. In a typical prior art siphon squirt toilet, about 70% of the fresh water is needed to power the squirt and start the siphon, only about 30% to clean the bowl through the rim. leave. In the priming toilet bowls herein, much less water is required to start the siphon, thereby allowing more water to be used to clean the bowl. Applicants have determined that more than about 50% of fresh water can be directed to the rim due to significant improvements in toilet bowl cleaning. In a preferred embodiment, more than about 60% and about 70% of water can be directed at the rim.

[0167] In addition to the factors noted above, another to maintain sufficient sealing depth of water in the reservoir area and / or prevent backflow of air from the reservoir into the ejection channel. The method is to keep the water flowing through the ejection channel and from there later after breaking the siphon. For example, in a bowl filled to the weir (ie, there is extra water that contributes to the siphon), a spout of more than about 950 ml / s to start and maintain the siphon in a trapway about 54 mm in diameter. Requires volumetric flow from the unit. This is a linear flow rate of 127 cm / s over the outlet port area of ^{7.47 cm 2.} The larger the trapway size, the higher the flow rate required to start and maintain the siphon, and the smaller the trapway, the smaller the value. The siphon breaks when the flow rate from the ejector is reduced to less than about 950 ml / s. By maintaining a volumetric flow rate from the ejection section of less than about 950 ml / s and more than about 175 ml / s (ie, a linear flow rate of 23.4 cm / s through ^{the 7.47 cm 2 region of the outlet port).} It prevents air from entering the closed ejection channel. When the bowl is fully filled to the level of the trapway weir, flow from the ejection section is stopped without loss of priming as long as the top of the ejection channel is located below the trapway weir. obtain.

Controlling such flush valve operation for squirt flushes and rim flushes can be done in a number of ways. One method uses solenoid valves as disclosed in US Patent Application Publication No. 2009/0313750 and US Pat. No. 6,823,535, of which relevant parts are incorporated herein by reference. It is due to that. This valve control method is a mere mechanical method, such as that disclosed in US Pat. No. 6,704,945, also of which the relevant part is incorporated herein by reference. It can be accomplished by modifying the valve. Alternatively, a flush actuation bar may be used that is balanced for the optimum performance of the two flush valves arranged in order as shown herein.

[0169] The wash actuator bar may be connected to a rotating rod and handle, or to another wash actuator using an adjustable flush connector. The adjustable flush connector provides an adjustable connection that compensates for differences in the placement of the rotating rod with respect to the valve assembly within the toilet bowl. This compensation allows most valve assemblies, wash actuation bars, and / or rotating rods to fit together. Adjustments made by the adjustable wash connector may include longitudinal movement along its length, rotation around its longitudinal axis, and / or rotation about its lateral axis.

[0170] Further, as discussed in more detail below, system performance can be enhanced by providing a "peeling" valve cover to facilitate the automatic priming action of the ejector. The cover serves to reduce the working force required to open the ejector flapper. In the present invention where the ejection channel is primed, the weight of both the water above and below the flapper requires more than twice the force of a conventional flapper valve. By peeling and opening the cover, the seal is torn and some water arrives, while the air recedes so that the cover opens more easily. In addition, during the initial priming action, when the valve is closed, the squirt is filled with air, and if the flapper suddenly opens, fresh water rushes in too quickly and the air in the squirt channel is a toilet bowl. Depending on the geometry of the eruption channel and its eruption channel, it may be captured and not sufficiently expelled. Further, embodiments herein include a priming and closed ejection path, so that when the toilet bowl requires the entry of water, an optional backflow prevention device, as further described below, will eject. It can be provided on the flush valve.

[0171] A preferred valve cover structure for use with a "peeling" valve cover may optimize valve performance. In particular, a locking element may be provided on the seal to prevent the seal from coming off the valve cover. In addition, valve assemblies that are associated with each other may be provided using link devices to maintain consistent wash performance. Such valve assemblies can be used to ensure proper and consistent alignment between valve bodies over time.

[0172] Stopping sufficient post-wash depth and / or water from entering the closed spout fluid passage through the spout port in the sump area is a rimless toilet bowl while the siphon is torn. It can also be achieved by keeping water flowing through the rim shelves, or through the rim channel in the relatively old toilet design. As the toilet system described herein includes a separate channel and valve mechanism to control the flow to the rim and ejection, the system will flow through the rim inlet port while the siphon is broken. Can be designed to continue. The flow of water to the rim inlet port is preferably sufficient to keep the water level in the reservoir area above the height of the spout port, but not enough to keep the siphon in the trapway. Is. In this way, additional safety measures may be taken to keep air out of the ejection channel and reduce dependence on the sealing depth within the reservoir region. It should also be noted that the flow through the gush and rim can be used together to maintain sufficient post-wash depth within the reservoir area.

[0173] A related area in which the present invention provides an improvement over prior art is in a highly efficient siphon toilet bowl with a wash volume of less than 6.0 liters, preferably less than 4.8 liters. The embodiments of the toilet bowl assembly of the present invention described herein are about 6.0 liters or less per flush in a single flush or dual flush assembly, while keeping the bowl extremely clean with low water usage. It is possible to maintain resistance to clogging, which is consistent with today's toilet bowls, preferably less than about 4.8 liters per flush. The embodiments of the priming toilet assembly herein can function with less than about 4.8 liters per wash, as less water needs to be passed through the ejection channel to initiate the siphon. It enables the production of extremely high efficiency toilet bowls that can function preferably at about 3.0 or less per wash and about 2.0 liters per wash.

[0174] Further, a second relevant area in which the present invention provides an improvement over prior art is in siphon toilets with larger trapways. Water consumption and toilet performance are significantly affected by resizing the trapway. In the present invention, the toilet bowl assembly is configured because turbulence and restriction to the flow is reduced by passing through a closed squirt fluid passage, including a primed squirt manifold and a primed squirt channel in a preferred embodiment. Various trapway sizes and volumes can be kept primed in siphon toilet bowls, which allows the toilet bowl assembly to maintain excellent flushing action and cleaning capacity.

[0175] In order to maximize the potential performance of the toilet system of the present invention, the closed fluid ejection path must be "primed", ie, filled with water and containing little or no air. Don't be. When the closed fluid ejection path and ejection channel contain a significant amount of air, such as after the toilet bowl is first installed or after major repairs or maintenance, the closed ejection channel is a potential system. It must be primed before it can be fully performed. Two basic requirements must be met for priming to occur, i.e. (1) allow water to flow into a closed fluid ejection path faster than leaving the closed ejection channel. It must also be (2) with respect to the air contained in the eruption channel and the closed eruption fluid path, through the flow of water into the closed eruption channel, or with the flow of water. There must be a route to escape to the flow.

[0176] The simplest method, which can be referred to as "manual priming action", to priming a closed squirt channel is to keep the rim valve closed, blocking or partially blocking the flow from the squirt port. , To open the squirt water flush valve assembly described herein. The ejection flush valve should be kept open until air bubbles escape from the channel into the tank and are no longer visible, at which point the ejection flush valve is closed and the outlet port is blocked. Can be released. Then, after refilling the tank, the system should be fully primed and ready to use with potentially full performance. In a preferred embodiment, the system is designed to automatically primate over the first few flushes after installation or loss of priming for other unexpected reasons (maintenance, repair, etc.). The same two requirements must be met here for automatic priming, but are system specific. Ensuring an automatic priming system will depend solely on the geometry and design of the squirt valve, the closed fluid squirt path including the squirt channel, and the spout port. As described in more detail below, the ejection flush valve preferably allows a high flow rate to enter the closed ejection channel and increases the flow rate (US incorporated herein by reference). A flush valve with a radius (such as that described in Pat. No. 8,266,723) can be used. In most closed ejection channel designs, the last part of the air trapped in the ejection channel can rise to the space just below the flapper (or other opening mechanism) of the ejection flush valve. Therefore, the valve design must also facilitate the escape of this remaining air. As described below, a gradually opening valve, such as a flapper that can be peeled off, can constrain the flow of water to one side of the valve and facilitate the escape of air around this flow. Certain patterns or ribs in the throat of the flush valve can also facilitate the escape of air in this way.

[0177] FIGS. 1-15, 17-19, and 29-34 show a first embodiment of a toilet bowl assembly generally referred to herein as assembly 10. The assembly 10 includes at least one spout water wash valve assembly 70 having a spout water wash valve inlet 71 and a spout water wash valve outlet 13. The squirt water washing valve main body 21 extends between the inlet 71 and the outlet 13 and defines an internal flow path. The ejection flush valve assembly may have a variety of configurations and may be any suitable flush valve assembly known in the art or developed in the future. Preferably, this is for illustration of the use of a cover with such a valve and float, and further with reference to various embodiments of the jet flush valve described below and shown in FIGS. 35-68. Relevant to are configured to resemble those described in Co-pending U.S. Patent Application Publication No. 2014/0090158, which is incorporated herein by. As shown in FIGS. 1-2 and 7-11, the jet flush valve assembly 70 is a rim flush valve assembly 80 (where the rim valve is) to control the flow through the jet flush valve assembly. , Which is described herein for assembly 80) has a shorter valve height outline. Each of the rim flush valve assembly 80 and the jet flush valve assembly 70 preferably has a cover 115 to which the float 117 is attached via a chain 119 or other link mechanism. Such features help provide a high degree of performance and buoyancy control in a particular flush valve design, as described in Co-pending U.S. Patent Application Publication No. 2014/0090158. However, it should be understood that other flush valve assemblies can also be used by operating in accordance with the principles of the present invention to provide improved washability.

[0180] In the illustrated embodiment, the rim 32 has contours or geometric features in which fluid is introduced into the bowl 30 through the rim inlet port 28 and formed within the inner surface 36 of the bowl 30. It is a "rimless" design in that it travels along. That is, the contour may be a similar feature formed along one or more shelves 27, or the upper peripheral portion 33 of the bowl 30. As shown, the shelves are embedded in the pottery of the bowl as best shown in FIGS. 29-34. The shelves, also referred to herein as rim shelves 27, are at least partially above the circumference of the bowl from the rim inlet port 28 along the inner surface 39 of the bowl 30 within the upper peripheral portion 33 of the bowl 30. Also, as best shown in FIGS. 30-34, it generally extends transversely within the embedded contour of the inner surface 36 of the bowl 30. The toilet bowl 30 may be of various shapes and configurations and may have various toilet seat lids and / or lid hinge assemblies. Since such closures are optional, they are not shown in the drawings and numerous such closures and assemblies are known in the art, thereby any suitable known or upcoming development. A lid can also be used with the present invention.

[0181] In an embodiment as shown in FIG. 3, the shelves 27 may extend around almost the entire inner surface by the time they are terminated, inducing a vortex effect for cleaning. The rim shelf design is also described in US Patent Application Publication No. 2013/0219605A1. Multiple rim shelves and multiple rim inlets can also be accommodated, as shown in the alternative "no rim" embodiment 410. Similar designs as shown in UK Patent Application No. 2431937A or any future modifications of such designs are also here where the bowl is formed without a conventional hollow rim and the water is fluid in the bowl. A shelf or similar geometry within the contour of the surface of the bowl as shown that allows it to enter the inside of the bowl at a location displaced transversely from the rim entrance through at least a partial path around it. It is directed around the undulating inner surface of the bowl within the upper perimeter portion that forms the feature and can be used as well. A standard rim channel with one or more rim outlet ports for introducing wash water into the inner region of the bowl, with a rim inlet port supplying the rim channel defined by the conventional upper rim. It should also be appreciated that may also be used in the embodiments described herein (see FIG. 16 and embodiment 110). Such rims may or may not be pressurized and may have various characteristics as described in more detail below with respect to embodiment 110. The rim features of embodiment 110 can be incorporated into the rimless version shown in FIGS. 1-3 or 28 without departing from the scope of the invention.

[0182] In assembly 10 as pointed out above, the shelves 17 may be embedded. As shown in FIGS. 30-34, the shelf 27 has a relatively constant, preferably constant depth d, measured transversely from the inner surface of the toilet bowl into the contour, and the shelf. It is within a contour having a height h measured in the longitudinal direction from 27 to the upper surface 47 above the shelf. The shelf width s varies from the rim outlet port along the rim flow path. The contour portion has an inwardly extending portion 43 and an upper surface 47 above the shelf portion 27 extending along the shelf portion, the shelf portion having the contour as shown in FIG. Resized to form a deeper shelf in an area with a shelf width s1 and a height h1 somewhat larger than its depth to accept a strong flow of fluid from the rim inlet port, the rear and front of the bowl. Maintains a moderately sized shelf size approximately halfway between the portions (see FIG. 31), where the rim flow is at the front of the bowl, as shown in FIG. Continue along the shelves towards (see s2 and s3). The depth d is relatively constant, but the height h begins to extend towards the front of the bowl (see heights h2 and h3) as the width of the shelves decreases (see, eg, s2 and s3). reference). Preferably, the depth in one embodiment of the specification remains between about 10 mm and about 30 mm. The height varies from about 35 mm to about 50 mm at the beginning 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 exemplified by s, where s is tangent from the first radius of curvature r at the embedded edge of the shelf to the second radius of curvature R where the shelf tilts downward. It is a cross-sectional measurement value obtained by measuring along the line. The shelf is at an angle α with the tangent from the first radius. The angles α in this embodiment vary and, as illustrated, are 7 °, 5 °, 7 °, 22 ° and 31 °, respectively, as the shelves travel along the path in FIGS. 30-34. .. As the angle increases, the radius increases and the shelf width s disappears towards the downward slope when the shelf terminates.

[0183] Depth d remains constant as the flow continues as shown in FIG. 33 from the front of the bowl to the opposite side of the bowl at the midpoint traveling towards the rear of the bowl of FIG. However, the height extends further from about 45 mm to about 60 mm at the midpoint of FIG. 33 to reach the rear of the bowl, where it is from about 50 mm to about 65 mm. When the height is extended (h4 and h5), the shelf 27 is reduced to a curve and finally terminated.

The ejection portion 20 has an inlet port 18 that fluidly communicates with the outlet 13 of the ejection flush valve 70, and an ejection outlet port 42 that is positioned at the lower or bottom portion 39 of the bowl 30. The spout port may be configured with a cross-sectional shape and size that varies to discharge the fluid into the reservoir region 40 of the bowl 30. As long as the closed ejection fluid path is maintained, the space must be primed and any hole or outlet must be below the waterline in the basin to avoid affecting the sealing depth of the ejection trap. As desired, additional optional areas or passages may be provided, including a plurality of additional passages or openings to form a space within the plurality of outlets or bowls. The additional outlet is preferably below the primary outlet. As best shown in FIGS. 3C to 3G, the shape of the internal ejector, including the space created by the geometry of the bowl around the channel 38, is larger than the channel itself, with inlets 18 and outlets. It extends between 13 and 13. The shape of the ejection portion is shown in the plan view, the bottom perspective view, the right side view, the rear view and the left side view, respectively, from FIGS. 3C to 3G. The shape or common area can change under the condition that the interior space of the ejector 20 remains primed during use.

The jet water wash valve 70 is preferably positioned at level L above the weir 45 of the trapway. The closed ejection fluid passage 1 preferably extends from the outlet 13 of the ejection flush valve 70 to the outlet port 42 of the ejection portion 20. After the assembly has been primed, the closed squirt fluid passage 1 may remain primed with fluid to prevent air from entering the closed squirt fluid passage before and after the flush cycle is activated and completed. can.

[0186] A closed squirt fluid passage inserts a space or area between the inlet and squirt passages to provide fluid communication through the squirt manifold inlet opening and outlet (not shown). Not shown) can be included. The toilet bowl assembly may have a rim manifold (not shown). Any such rim manifold communicates with the outlet 81 end of the rim wash valve assembly 80 and delivers fluid to the rim inlet and a rim manifold inlet opening for receiving fluid from the outlet 81 of the rim wash valve assembly 80. Must have an exit to do. Such rims and ejection manifolds are described in the embodiment of FIG. In embodiment 10 herein, the rim 32 is a rimless shelf (conventional rims with rim channels can also be used). The shelves extend at least partially around the bowl.

[0187] The assembly preferably comprises a tank 60 that fluidly communicates with a source of fluid (SF), which may be urban water, tank water, well water, or the like, thereby mounting. The assembly is attached and the tank 60 is capable of accepting fluid flow through the tank into the filling valve. The tank preferably has at least one filling valve 66. The fill valve is any suitable fill valve on the market or will be developed in the future, as long as it provides sufficient water supply to maintain the desired amount in the tank and fulfills the functions described in the present disclosure. It may be as there is. The tank 60 may be one large open container holding the assembly of both the rim valve and the jet flush valve, as shown in FIGS. 1-13. The tank may be modified as described below for embodiment 1010 to have at least one ejection reservoir and at least one rim reservoir. If a split reservoir is provided, the ejection reservoir may include a filling valve or ejection filling valve along with at least one ejection flush valve assembly 70, and the rim reservoir may include at least one rim flush valve assembly and a tank or rim filling valve. And can be included. If desired, such a rim reservoir may further accommodate the overflow pipe 91 on the rim flush valve assembly 80.

[0188] The toilet bowl assembly of FIGS. 1-13, as in other embodiments herein, is about 6.0 liters or less, preferably about 4.8 liters or less, even more preferably about 2.0. It can operate with a wash volume of liters or less.

[0189] The bowl area 40 preferably has a squirt trap 41 defined by the inner surface 36 of the bowl 30 within the lower portion 39 of the bowl 30. The ejection trap 41 has an inlet end 46 and an outlet end 50. The inlet end 46 of the ejection trap receives fluid from the internal region 37 within the ejection outlet port 42 and the lower portion 39 of the bowl 30, and the outlet end 50 of the ejection trap 41 includes an inlet 49 to the trapway 44. , Flow here. The ejection trap has a sealing depth as further described below. For example, measurements of sealing depth, ejection path, and depth x as shown in embodiment 10 shown in FIGS. 1-3 and 29-34 are described below. All modifications are readily incorporated and operational in embodiment 110 of FIG.

[0190] To keep a siphon flush toilet assembly such as Assembly 10 in a primed state, the first steps are described above, and the present specification comprising 110, 1010, 210, 310 and 410 and the like. It is to realize a toilet bowl assembly having features as described for various other embodiments of the book, in particular where the closed squirt fluid passage 1 having the squirt channel 38 inside is a squirt flush. The squirt fluid passage that extends from the outlet 13 of the valve 70 to the outlet 42 of the squirt section 20, thereby closing after priming, is a squirt fluid passage in which the air is closed before and after the flush cycle is activated and completed. Can remain primed with fluid to keep out of the toilet. The wash cycle is actuated by any suitable actuating device such as the wash handle H. In a preferred embodiment, the outside of the pottery and the handle H are formed from, or incorporated into, a material that provides an antibacterial surface. After initiating the wash cycle with a wash actuator such as a handle, the handle has a portion operably connected (which may or may not be removable) to the wash actuation bar 75.

[0191] The valve can have an actuator that can open both at the same time (this may be done using a standard actuation bar of a wash handle) or provide a balanced approach. By using a flush actuating handle, such as one, it is possible to have lift timing changes and / or adjustments based on the weight of each flush valve cover. As best shown in FIG. 15, the handle H is operably connected to a rotary rod P having a rotatable mobile link mechanism RL. Any hinge, pin connection, washer, or other rotating connector may be used. The wash actuation bar 75 has a counterbalance point BP for a movable connection with the rotary rod P through the link mechanism RL. A similar movable and rotatable link mechanism RL'(which may be the same as the rotatable link mechanism RL) connects the rotating rod and its link mechanism RL to the wash actuation bar 75 at the equilibrium point BP. The equilibrium point is selected by a design that works with the wash valve to finely and mechanically adjust the opening time of each valve when the handle H is pushed down to activate the wash cycle. When the handle H is pushed down, the rotary rod P and the link mechanism RL are pushed up at the end having the link mechanism RL. This then pulls up the actuation bar 75. It is possible to provide a bar 75 with multiple holes to provide a link mechanism for variable equilibrium points so that only one bar needs to be manufactured, the weight of various valve covers and washing with water. Can be used for timing patterns. Although flush-operated assemblies are described with respect to siphon flush toilets, it is understood that flush-operated assemblies can be used with any style of flush toilet, including flush toilets.

[0192] As shown in FIGS. 69-70 and 85, the assembly kit 1100 may be provided to improve operation and communication between the handle H and one or more valves. The assembly kit 1100 may have a wash actuated assembly 11144 comprising a rotary rod P, a wash actuated bar 1175, and a connector 11260. One end 11142 of the rotating rod P may be connected to a handle H located on the outside of the tank, or another water wash actuation mechanism, while the opposing end 11143 of the rotating rod P may be connected. , Can be connected to connector 11260 using a rotatable connection. The rotary rod P may be a standard or conventional rotary rod, or may be tailored to the size and configuration of the tank. As shown in FIG. 85, the placement of the connecting element 11145 on the rotating rod P, which may be one or more openings, is determined by the manufacturer of the rotating rod, the valve opening, or the rotating rod with respect to the toilet tank. Can be positioned in different arrangements along. Each manufacturer may have a slightly different arrangement with respect to the connecting element 11145 along the length of the rotating rod P, or the shape of the rotating rod P itself may be changed. Modifications of the embodiments described herein for connector 11260 may be used to compensate for different arrangements of connecting elements, such as substantially any rotating rod P. Furthermore, other non-conventional water washing actuating devices are intended to conform to embodiments of the present invention. Modifications of the connector embodiments described herein are of handle H and rotary rod P with respect to valve body portions 1131 and 1121 due to differences in handle and rotary rod configuration and / or tank size. It can also help mitigate the effects of precise positioning differences. As such, the connector can ensure that the valve is provided with the appropriate amount of lift to trigger the desired operation.

[0193] As shown in FIG. 85, connector 11260A has a connection element 11145 in the rotating rod P at the first chain end 11264 forming the first rotatable connector 11153 and a second. It is shown as a chain C3 hooked to a connecting element 11261 on a wash actuated bar 1175 at the second chain end 11266 forming the rotatable connector 11157 of the. The flush actuation bar 1175 and the rotary rod P are described in more detail below with respect to the use of the adjustable flush connector 11150 as illustrated in FIGS. 69-72 in each modification of the embodiment. And may be the same as the rotating rod. Depending on the type of connector 11260 used, the connecting elements on the rotating rod, and the connectors, can be modified to form a rotatable connection between these elements. The connector 11260 may rotate at least a partial rotational motion around the longitudinal axis LAc (FIG. 85) around the axis LAc with respect to the wash actuation bar 1175, whereas the rotary rod P is of the axis LAc. It should be configured so that it does not rotate around. In addition, the first rotatable connector 11153 between the rotating rod P and the connector 11260 should be rotatably positioned around the lateral axis TAp of the rotating rod P. The second rotatable connector 11157 between the wash actuated bar 1175 and the connector 11260 should be rotatable and rotatable around the horizontal axis TAb of the wash actuated bar 1175. Preferably, the connector 11260 is an adjustable flush connector 11150, as shown in FIGS. 69 and 70 and described in more detail below. An additional modification of this embodiment of the connector that is sufficient to provide a rotational movement of the wash actuation bar 1175 with respect to the rotary rod P is also an acceptable connector and is shown in FIGS. 86 and 87.

[0194] FIGS. 86 and 87 show additional modifications of connectors 11260B and 11260C that cause rotational motion around the longitudinal axis LAc. The rotational movement around the longitudinal axis LAc of these modifications of the connector is preferably provided by a ball / socket connector 11154 that is located along the length lc of the connector at the longitudinal center point LC. A similar ball / socket connector 11154 is described in more detail below with respect to a modification of embodiment 1100 using the adjustable flush connector 11150 shown in FIG. 69 as an alternative embodiment to connector 11260. With respect to FIG. 87, the spacer 11262 may be placed between the ball / socket connector 11154 and the wash actuation bar 1175. The spacer 11262 may be provided so that the wash actuation bar 1175 can more easily rotate around the longitudinal axis, but is not required for the connector to function properly.

[0195] In FIG. 85, the first rotatable connector 11153 between the connector as illustrated as chain 11260A and the rotating rod P may be a hinge type connection, where pin 11146.

The hook is inserted into the hole, the use of a protrusion on one element that is inserted into an opening or recess on the other element, a ball-and-socket joint, and even other known connections. It is understood that any connection between the connector 11260 and the rotating rod P that allows rotation around the lateral axis TAp of the rotating rod P can be used. Similar connections between the rotary rod P and the connector 11260 are described in more detail below with respect to the adjustable flush connector 11150 of FIGS. 69-72.

[0196] Similarly, the second rotatable connector 11157 between the wash actuated bar 1175 and the connector 11260 is the connection used for the first rotatable connector 11153 between the connector and the rotating rod. It may be the same or different. As shown in FIGS. 86 and 87, a hinge type connection 11268 may be used, where the protrusion 11263 is integrally formed on the connectors 11260B and 11260C. These protrusions 11263 may be inserted into the opening 11165 in the wash actuated bar 1175 by spring and / or torsional compression of the protrusions and / or the sides of the wash actuated bar. The wash actuated bar 1175 may rotate freely around the horizontal axis TAb of the wash actuate bar. A second rotatable, including the use of pins through the openings of both elements, hooks inserted into the openings, ball-and-socket joints, and other rotatable connections known or will be developed. Additional types of connectivity devices suitable for use with the connector 11157 are also contemplated. Similar connections between the connector 11260 and the wash actuation bar 1175 are described in more detail below with respect to the adjustable wash connector 11150 of FIGS. 69-72.

[0197] Although some exemplary modifications of the connector, 11260A-11260C, are described herein, the connector 11260, which provides rotational motion about the longitudinal axis LAc, can be used in wash-operated assemblies. Is understood. Such rotational movement may be such that the wash actuation bar can be placed in the proper position and the valve assembly can be actuated. Preferably, the connector 11260 may be an adjustable wash connector 11150 and the wash actuated assembly may be configured as described below.

The opening 11158 of the first rotatable connector 11153 is preferably aligned with the opening at the end of the rotating rod 11143. After the openings are aligned, the pins 11146 can be inserted through the openings and secured from the side on which the pins were originally inserted to the opposite side. The pin is preferably fixed by inserting the cotter pin 11139 into the opening at the end of the pin inserted through the opening. Other methods of fixing the pins are also possible, including spring-loaded pins, split pins, or preferably other pins that prevent the pin 11146 from being removed from the opening. A method of inserting the pin 11146 through the opening and connecting the adjustable wash connector 11150 to the rotary rod P is preferred, but two elements that allow rotation of the adjustable wash connector 11150 with respect to the rotary rod P are provided. It is understood that the method of connecting can also be used.

The ball / socket connector 11154 allows the second section 11152 to rotate around the longitudinal centerline CL of the washable connector 11150 which is adjustable with respect to the first section 11151. The ball / socket connector 11154 can also swing the second section 11152 back and forth like a pendulum along a plane that intersects the longitudinal axis, and this movement is on the longitudinal axis of the second section 11152. It is possible to give the bottom of the tank a degree of freedom that is not vertical at all times. The ball / socket connector 11154 not only rotates around the longitudinal axis of the second section 11152 with respect to the first section 11151, but also sways back and forth along the plane intersecting the longitudinal axis of the second section.

However, only one of these methods can rotate sections 11151 and 11152 with respect to each other, including hooks and loops or hinged connections that use pins with openings in one or both sections 11151 and 11152. It is understood that any type of connector that allows it can also be used. It is also understood that the adjustable flush connector 11150 may be a single unit that does not allow movement or rotation between the first section 11151 and the second section 11152.

[0202] Each of the first and second sections may be made independently of either the polymeric material or the metal, preferably these are dissimilar materials to prevent the mating parts from binding. The first section 11151, including the ball / socket connector 11154, is preferably molded from polyester material as a single unit. The second section 11152 is preferably formed from acetal material. Other materials, including other polymers as well as various metals or alloys, are also contemplated for use in forming the first and / or second section. 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, can also be used to form the first and second sections of the adjustable wash connector 11150.

The second rotatable connector 11157 is configured to connect the wash actuated bar 1175 to the adjustable connector 11156 at the equilibrium point BP on the wash actuate bar 1175. The configuration of the second rotatable connector 11157 is such that the wash actuation bar 1175 is rotatable around a lateral straight line extending from side to side of the adjustable connector 11156. Certain preferred configurations are discussed below. The equilibrium point BP is preferably when the wash actuation bar 1175 is lifted, the lift is typically the push of the handle H or the lift of the end 11143 of the rotating rod P connected to the adjustable wash connector 11150. It occurs in response to, but is arranged so that the timing of opening each valve with respect to the other is optimized. An embodiment of timing optimization between valve cover opening has already been described above and is shown in FIG.

[0208] The water wash actuated bar 1175 preferably has a bar body 11169 with a _{preferred length l FB} of the water wash actuated bar 1175 between about 90 mm and about 130 mm. The preferred width w _FB of the wash actuated bar 1175 is between about 2 mm and about 5 mm, and the preferred height h _FB of the wash actuate bar 1175 is between about 5 mm and about 15 mm. The cross section of the water wash actuating bar 1175 may be substantially rectangular. However, as understood by those of skill in the art based on the present disclosure, cross sections of any shape may be used, including circular, oval, hexagonal, triangular and the like. The wash operation over 1175 may be made from a polymeric material, metal, or metal alloy, preferably injection molded using acetals. However, any method of manufacture may be used to make the wash actuated bar, including resin casting, compression molding, or three-dimensional printing.

[0209] The wash actuation bar 1175 preferably has two sidearms 11177. The two sidearms 11177 form and define a large opening 11164 within the bar body 11169, which is preferably disposed around the equilibrium point BP of the wash actuated bar 1175. The large opening 11164 defined by the sidearms 11177 can extend along the longitudinal axis of the wash actuation bar 1175. The large opening 11164 preferably has an oval cross section. However, any shape for the large opening 11164 is contemplated, including circular or rectangular. The sidearms 11177 are preferably symmetrical about the longitudinal axis of the wash actuated bar 1175, but the symmetry of these elements is not necessary. For the preferred shape of the wash actuation bar 1175, the sidearms 11177 should be parallel to each other at at least one position along their length. The size for the large opening 11164 is intended to be such that at least a portion of the entire adjustable flush connector 11150, including the adjustable connector 11156, can be inserted through it.

[0210] Where the two sidearms 11177 are parallel to each other, the two small openings 11165 are formed laterally through the sidearms 11177, which are formed as part of the wash actuation bar 1175 and define the larger opening 11164. Can extend in the direction. The small opening 11165 is preferably circular, but may have any shape that allows rotation of the connecting element, and at least the bottom of the small opening 11165 should be substantially curved. be. The small opening 11165 is preferably configured to correspond to or accommodate two protrusions 11163 extending from the side of the adjustable connector 11156.

[0211] To attach the wash actuation bar 1175 to the adjustable connector 11156 and form a second rotatable connector 11157, the adjustable connector 11156 extends from one side of each adjustable connector 11156. The two protrusions 11163 are provided. The two protrusions 11163 are preferably arranged towards the top of the adjustable connector 11156, preferably on the same line extending across the adjustable connector 11156. The protrusion 11163 preferably has a cylindrical shape. However, any cross-sectional shape, such as an egg shape, is conceivable. The cross-sectional shape is preferably round at least on the bottom edge so that the protrusion 11163 can rotate within the small opening 11165 of the wash actuated bar 1175.

[0212] As a method of forming the second rotatable connector 11157, the two protrusions 11163 are snapped into the small opening 11165 of the wash actuated bar 1175, which is lateral to the wash actuate bar 1175. A rotatable connection is formed around the protrusion 11163 around the shaft. The protrusion 11163 is snapped into place, preferably by using the spring and / or torsional compression of the protrusion 11163 and / or the sidearm 11177, whereby the protrusion 11163 is within the small opening 11165. Locked in place. The protrusion 11163 may operate by a spring mechanism so as to penetrate into the small opening 11165, and the preferred end 11179 of the protrusion 11163 facilitates insertion of the protrusion 11163 into the small opening 11165. It may be angled. If it is desirable to remove, the angled end 11179 can also assist in removing the protrusion 11163 from the small opening 11165. Detachable connections are preferred, but the protrusions 11163 may have a shape and / or size that makes removal difficult or makes removal a highly impractical task.

[0213] Any type of connection that is rotatable around the horizontal axis of the wash actuated bar 1175 is an acceptable alternative configuration to the second rotatable connector 11157 by one of ordinary skill in the art. Understood. The use of an opening through the adjustable connector 11156 and a second section 11152 of the adjustable wash connector 11150 through which a pin can be inserted and passed also also makes the wash actuation bar 1175 into an adjustable wash connector 11150. It is intended to form a second rotatable connector 11157 to connect. In one such embodiment, two or more openings are needed on the second section 11152. The openings extend across the second section and are positioned at various points along the length of the second section. Two or more of the openings may extend across the second section at one or more different angles with respect to each other. Two or more openings can allow the adjustable connector 11156 to be longitudinally movable and rotatable and rotatable. Similar arrangements are also available to connect the wash actuation bar 1175 directly to the second section 11152 of the adjustable wash connector 11150 without using the adjustable connector 11156 as described above. Can be used. Other possible connections may include a threaded surface on the protrusion 11163. A mating threaded female piece with a smooth outer surface can also be used to detachably secure the wash actuation bar to the adjustable connector and form a second rotatable connector. be. Riveted connections can also be used, which can form either removable or permanent connections.

[0214] FIG. 69 comprises a first valve assembly, a second valve assembly, a toolless wash actuation bar and an adjustable wash connector, connected to a rotary rod P and a handle H. An embodiment of an assembly kit 1100 with a wash-operated assembly as shown is illustrated. Alternative kits include the following tank / bowl gasket tools as shown in FIGS. 83 and 84 below, float attachments as shown in FIGS. 88-90, or FIGS. 80-81. It may also accommodate one or more of the multiple wash valve assemblies as shown in. FIG. 69 shows a connection that associates action on handle H with valve opening. When the handle H is pressed, the rotating rod P vertically lifts the adjustable wash connector 11150, which in turn moves the wash actuation bar 1175 vertically at the equilibrium point BP. The wash actuated bar 1175 is preferably connected to a first valve assembly 1180 at the first portion 11161 of the bar 1175 and a second valve assembly 1170 at the second portion 11162 of the bar 1175. .. The first valve assembly 1180 is preferably a rim valve assembly and the second valve assembly 1170 is preferably an ejection valve assembly. The rim valve assembly 1180 and the squirt valve assembly 1170 are described herein in various embodiments of the primed toilet bowl and are similar to those described in the earlier embodiments as valves 80 and 70. , Or may be the same. One or more different types to allow the wash actuated bar 1175 to be used with the wide range of connector styles used on chains C and C1 connecting the flush actuated bar 1175 to each valve assembly 1170 and 1180. Connector pieces may be placed on the first portion 11161 and / or the second portion 11162 of the wash actuated bar 1175, including snaps as shown in FIG. 69, or other female fittings. Similarly, hooks or other male fittings may be included in one or both of the first portion 11161 and the second portion 11162.

[0215] The placement of the equilibrium point BP between the adjustable connector 11156 and the wash actuation bar 1175 can affect the timing of when the valve covers 1182 and 1173 open. The valve covers 1182 and 1173 can be set to open simultaneously, or siphon priming as described with respect to FIG. 15 by allowing the rim valve cover 1182 to fully open before the ejection valve cover 1173 begins to open. It can be set to optimize performance in the toilet bowl.

[0216] When the flush cycle is activated, the fluid flows through at least one rim valve, here through the rim flush valve assembly 1180, and at least one ejection flush valve, ejected flush valve assembly 1170 as illustrated herein. Supplied through. The configuration of the closed eruption fluid passage is such, and the timing of the eruption cycle is optimized to keep the closed eruption fluid passage in the primed state after the completion of the eruption cycle. The ejection mechanism and timing may be the same as the optimized performance described in various embodiments 10, 110, 210, 310, 410, etc., and the examples contained herein.

[0217] In one embodiment of the method herein, after actuating the ejection cycle, the flush actuating bar allows fluid to pass through at least one ejected flush valve assembly to keep air out of the outlet and trapway. It operates to supply at a flow rate sufficient to generate a siphon within. The flow rate is then reduced through the ejection channel for about 1 second to about 5 seconds until the siphon breaks, and the flow is maintained at least until the outlet port is covered.

[0218] The fluid is also preferably supplied through at least one rim ejection valve assembly in the ejection cycle. When first installed, the toilet bowl will pass through the spout water flush valve assembly outlet with sufficient flow to prevent air from entering the spout port until the reservoir is filled with fluid as described above. By supplying, it may be necessary to primate first. The associated flow rates for performing these steps are outlined elsewhere herein. The toilet assembly can be auto-primed as described above, and all or virtually all of the air will be expelled from the ejection channel when the toilet bowl is in a state of injecting air into the ejection channel. Is preferable. For general performance, a small amount of air is closed, preferably containing up to only about 100 ml of air in one embodiment, such as embodiment 10, as shown herein, while maintaining good operation. Although it should be allowed to enter the fluid ejection path, acceptable performance may include an additional amount of air, but preferably no more than about 500 ml of air to avoid performance degradation. .. The specific amount can vary depending on the geometry of the bowl.

[0219] Toilet bowls are typically used when the toilet bowl is first installed, for example, as pointed out above, although other situations such as plumbing or maintenance can also cause such situations. Is in a primed state. When the user can, of course, perform a manual intervention to prime the toilet assembly after installation, or when configured, the toilet bowl is out of the first few flushes of the toilet bowl without the user's manual intervention. One or more can be automatically primed.

[0220] As shown herein in FIGS. 1-3 and 29-34, the toilet bowl can expel virtually all air with as little water washing as about 3 times, but individually. Depending on the shape of the toilet bowl, the number of times required may be large or small. For automatic priming to be completed, there are two conditions: (1) the flow rate of the fluid through the ejection flush valve is that of the fluid leaving the outlet port to provide sufficient energy to displace the air. The conditions must be met that it must be greater than the flow rate and (2) air must be provided with a route to escape up from the outlet or through the spout water wash valve assembly. This can be achieved through modification of the geometry and / or cross-sectional area of the ejection channel and / or outlet port, and / or by modifying the ejection valve to improve performance. Therefore, it is preferred to use a jet flush valve that can direct high energy and high velocity flows through the ejection channel into a closed ejection fluid path. Suitable valves have a streamlined valve body configuration and are incorporated herein by reference with respect to the teaching of valves with rounded inlets and / or weighted covers. It is described in 266,733 and co-pending US non-provisional patent application No. 2014/0090158. Other suitable flush valves are commercially available and are described elsewhere herein with respect to other embodiments of the toilet assembly described below where the same flush valve can be used (eg, below). See also FIGS. 35-5 68 herein for better air release from the peeling capacity as described). In addition to gradually lifting the cover, the internal ribs of the star pattern can also affect the rate of air discharge as further described below.

[0225] The tank 60 should also include at least one fill valve 66 and an overflow pipe, such as the overflow pipe 91 shown in the above embodiment, which is optionally associated with a rim wash valve. The tank 60 can be formed as a single open reservoir that houses both the squirt and rim wash valves in one area as shown in FIG. 19, or, in the alternative, FIG. 20. Can be made as two separate reservoirs as shown in embodiment 1010. The overflow pipe is not the flow of the jet flush fluid JF through the jet flush valve (known or developed in the art) to eliminate any opportunity for air to enter the closed jet fluid path 1. It should be operated from the flow of the rim wash fluid RF out of the rim wash valve (which is associated with the valve body in any way). The rim path may remain open to air as long as the properties of the invention are not affected by the connection to the overflow tube within the rim path.

[0226] The assembly of the ejection flush valve 70 and the rim wash valve 80 is a standard commercial wash valve, including various designs known in the art or developed in the art, such as the Fluidmaster 502 wash valve. Valve and flapper designs can also be incorporated. The rim valve may be electrically, mechanically, or computer operated. Preferably, the toilet bowl assembly 10 is separately configured to deliver fluid, such as flush water, to at least one jet flush valve assembly 70, which is configured to deliver fluid to the ejector 20, and to deliver the fluid to the rim outlet port.

An example of a flush valve assembly known in the art that may be preferred in embodiments of this specification is found in US Pat. No. 8,266,733B2, which is incorporated herein by reference. Can be issued. The two valves can be opened and closed at the same time, or at different times in the wash cycle to further optimize performance. It is desirable to open the rim wash valve before opening the spout wash valve in order to clean the bowl with cleaner post-wash water. In a preferred embodiment of 6.0 liters / 1 water wash, the rim water wash valve is opened immediately after the start of the water wash cycle and is closed in about 0.1 to about 5 seconds after entering the cycle, while the jet water wash valve is , It opens in about 1 to about 5 seconds after entering the cycle and closes in about 1.2 to about 10 seconds.

[0228] In very low volume flush toilets with 3 liters / 1 flush, the rim flush valve is opened immediately after the start of the flush cycle and closed in about 1 to 3 seconds after entering the cycle, while ejecting. The flush valve opens in about 0.1 to about 3 seconds after entering the cycle and closes in about 1.2 to about 3 seconds. In embodiments herein, when using a 54 mm diameter trapway, only about 1 liter of water flowing from a fully primed closed ejection channel is required to initiate the siphon, and the bowl washes. Allows the application of the present invention to flush toilets operating in volumes of 2 liters or less, depending on the desired effectiveness of the and the amount of water directed to its function.

The upward protrusion 11222 preferably has a size that fits within the hook shape formed by the first link 11210. _{The height h UP} of the upward protrusion 11222 of the second link 11220 is such that the rim valve main body 1131 and the ejection valve main body 1121 are fixed to each other and cannot move toward or away from each other. It may be high enough to interlock with the second vertical section 11213 of the first link 11210. _{The preferred height h UP} of the upward protrusion 11222 is from about 2 mm to about 5 mm, but the height h _HE of the horizontal element 11223 and the first vertical section 11212 and the second vertical section 11213 of the first link 11210. _Depends on the height of h 1VS and h _2VS . _{The preferred length l UP} of the upward protrusion 11222 is from about 1 mm to about 5 mm. This preferred length may be such that the upward protrusion 11222 is selected to fit snugly within the hook shape of the first link 11210, whereby both the valve assemblies 1180 and 1170 are oriented towards each other.

For example, a single rigid article can be attached to both valve assemblies. Such an article should be able to hold the distance d _V between the two valve assemblies 1180 and 1170 substantially constant. It should also be noted that the valve bodies 1121 and 1131 may be formed as a single unit, thereby eliminating the need for the link device 11200.

[0244] Preferably, both the first link 11210 and the second link 11220 are made of a rigid material. However, the flexible material can also be used for one or both of the links. If the upward protrusion 11222 is made of a compressible material, its length l _UP is increased so that the upward protrusion 11222 can be compressed and fitted into the hook shape of the first link 11210. It may be a thing.

[0246] One possible method of attachment to the multiple valve assembly 11205 according to this embodiment is to attach one of the valve assemblies 1180 or 1170 in the tank and then attach the second valve assembly 1180 or 1170 separately. That is. Each valve assembly is preferably mounted and secured separately to the bottom of the tank using conventional tank / bowl mounting methods. In addition, tank / bowl gasket kits can be used as described below. Each valve body 1121 and 1131 may be inserted through a separate hole in the bottom of the tank. After installing the second valve assembly 1170, the first link 11210 and the second link 11220 are preferably interlocked. By using this method, one valve assembly can be removed, repaired or replaced without adjusting or removing the other valve assembly.

[0247] Another embodiment of the multiple valve assembly 11205 including the link device 11200 may have a single multiple flush valve assembly 11206 as shown in FIGS. 80 and 81. The single multiple flush valve assembly 11206 may include both a first valve assembly 1180 and a second valve assembly 1170 that are prepared together as a single unit. The single multiple flush valve assembly 11206 may have a first link 11210 and a second link 11220 as described in the above embodiment, which are permanently attached to each other. In addition, the first and second valve bodies can be molded as a single structure. The attached link device 11200 is preferably permanently attached to both the first valve assembly 1180 and the second valve assembly 1170 to form a single multiple flush valve assembly 11206. For a single multiple flush valve assembly 11206, the entire structure is permanently connected, but the link device 11200 may be a separate element, a separate first valve body 1131 prior to installation in the toilet bowl. And a second valve body 1121 are permanently connected to form a single multiple flush valve assembly 11206.

[0248] Preferably, the two valve bodies 1121 and 1131 and the connecting parts 11207 linking the two valve bodies are integrally formed with each other to make a single multi-valve assembly 11206. Can the two valve bodies 1121 and 1131 be as described in any of the embodiments disclosed herein, such as 10, 110, 210, 310, 410, 1010, 1110? , Or a conventional valve body known in the art. Preferably the connecting parts 11207 of the same material can be molded together with the valve bodies 1121 and 1131 so that the entire structure is a single part. The connecting component may also be permanently connected to the valve bodies 1121 and 1131 after formation. The connecting component 11207 is preferably of a size sufficient to maintain a constant distance between the valve bodies, depending on the material used.

Has. The length l _CP depends on the distance between the valve openings in the tank. The connecting component 11207 preferably has a rectangular cross-sectional shape when viewed across the tank. The shape of the cross section is intended to be arbitrary, and the shape may be circular, oval, triangular, octagonal or the like.

[0249] Another embodiment comprises a mounting method using a single multi-wash valve assembly 11206, wherein the first valve assembly 1180 and the second valve assembly 1170 are permanently connected to each other. .. In addition, this mounting method can be used to mount two separate valve assemblies 1170 and 1180 when the link device 11200 is interlocked before the valve is mounted in the tank. In an embodiment comprising a single multiple flush valve assembly 11206, both the first valve body 1131 and the second valve body 1121 interlocking with the first valve body 1131 are simultaneously mounted in the tank, a conventional tank / bowl mounting method.

If not permanently connected, the separate valve assemblies 1170 and 1180 may be attached in a connected form. If so, it is contemplated that the separate valve assemblies 1180 and 1170 can be disconnected from each other and removed individually from the tank. However, individual removal is difficult or impossible with a single multi-wash valve assembly 11206, where the first valve assembly 1170 and the second valve assembly are permanently attached to each other. Be done.

[0250] In one embodiment, such as the toilet bowl assembly 110, for separating the fluid flow introduced into the bowl assembly 110 from at least one flush valve assembly and delivering different fluid volumes to the ejector 120 and the rim 132. There are separate manifolds. It allows fluid to enter the bowl through one toilet inlet, flow into a single open manifold, and then travel downward in an uncontrolled or gravity controlled manner into the ejector 120 and rim 132. Distinguished from traditional toilet design. In such prior art designs, the amount and nature of fluid flow to the rim or direct ejection is difficult to control and typically favors ejection over the rim due to gravity and momentum of flow. While isolating the fluid flow to the ejection section 120 and the fluid flow to the rim 132, the fluid flow was controlled and the ejection section and the rim received the desired flow rate. In addition, this makes it possible to maintain a closed squirt fluid path 101 that includes a primed squirt channel 138 and preferably a primed squirt manifold 112.

[0251] The optional ejection manifold 112 is preferably preformed in pottery bowl porcelain or other manufacturing material, configured in a laminated position, and / or in parallel with the rim manifold. Manifolds can be parallel, but not at exactly the same level. The ejection manifold 112 may have an ejection manifold outlet opening 116 for delivering fluid to the ejection inlet port 118. The rim manifold 122 is intended to receive various volumes, eg, about 0.1 liters to about 5.5 liters of fluid, preferably from about 0.5 liters to about 4.5 liters from the rim wash valve assembly 180. May include a rim manifold inlet opening 124 configured in. The rim manifold 122 also has a rim manifold outlet opening 126 for delivering fluid to the rim inlet port 128. The fluid flow through the ejection section 120 travels directly down the ejection channel 138, exits the ejection outlet port 142, and enters the reservoir region 140 at a different timing than the water passing through the rim channel 134 enters. One of the flows can be stopped before the other flow, but the flows can preferably occur simultaneously throughout at least part of the washing cycle. These flows are selected to maximize cleaning of the internal surface 137 of the toilet bowl 130 before draining the reservoir area 140.

[0252] In another embodiment, the rim channel 134 may be powered directly by pipe pressure from a typical residential or commercial pipe line. The opening and closing of the flow to the rim can be electronically controlled by a mechanical pilot valve similar to that currently used as a toilet filling valve, or by a solenoid valve.

[0253] Bowls herein, such as bowls 30, 130, may have different configurations, but most bowls are generally round or elongated oval when viewed transversely from the top of the bowl. Alternatively, it is preformed so that it has an oval shape. In the embodiments described and illustrated herein, the bowl 30 generally has an elliptical shape. The bowl 130 is provided on its upper circumference and has a rim 132 defining a rim channel 134. The rim channel includes an inlet port 128 (at the transition point between the manifold and the rim channel where the cross section of the rim channel becomes more uniform) and a bowl assembly 110 that fluidly communicates with the rim manifold outlet opening 126. It has at least one rim outlet port 129, preferably a plurality of such outlets, in fluid communication with the internal region 136 of the. The bowl 130 is provided such that the ejection channel proceeds preferably along the outer surface 135 of the bowl 130 or within the walls of the bowl and the ejection outlet port 142 is located within the lower portion 139 of the bowl 130. It further has a ejection part 120.

[0254] In various embodiments herein, such as the toilet bowl 10, the ejector 20 directs the fluid to the pool area 40, then to the inlet to the trapway 44, and to the toilet bowl outlet O that can be connected to the sewage outlet. At least one ejection channel 38 having an ejection outlet port 42 configured to eject is defined.

[0255] In the embodiment of FIG. 16, a portion of the flush water is passed through the rim channel 134 and through the opening 129 positioned in the rim between the channel 134 and the internal region of the bowl 130. It provides liquid communication, sprinkles water over the entire surface of the bowl 30 and serves to wash the bowl in the wash cycle. The water flowing through the rim channel 134 is also pressurized in some embodiments herein after exiting the rim outlet port 129 or after exiting an external fluid source as described above. Can be done. Depending on the size of the outlet port, the geometry of the toilet bowl, and the flow rate, pressurization can cause a strong compressive flow of water, cleaning the bowl and contributing to the siphon action. The rest of the flush water from the separate ejection valve assembly 170 is directed to the ejection part 120.

[0256] The ejection portions 20, 120 and at least one ejection channel 38, 138 of the present specification provide a stronger high-speed flow of flush water to the trapway inlets 44, 144, whereby the toilet bowl is further enhanced. It can be designed with a large diameter trapway, but it minimizes bends and constrictions that can affect movement, and performance in removing large amounts of excrement for non-squirting and / or rim-squirting bowls. Attention should be paid to improve.

[0257] At least one ejection channel 38 extends within the toilet bowl assembly 10 and is designed to orbit over the outer surface of the toilet bowl 30, but is generally of the inner region wall 36 of the bowl 30. It is also positioned to at least partially enter the space defined within the toilet bowl assembly body 10 below or directly below. Multiple ejection channels of different sizes may be used, for example, two symmetrical channels on either side of the bowl 30 deliver a "double-fed" flow of fluid to the ejection unit 20.

[0258] The outlet port 42 is configured to discharge the fluid from the ejection channel 38 into the reservoir region 40, which fluidly communicates with the trapway 44. The spout port 42 is preferably about 1.0 cm to about 10 cm, preferably about 1 cm to about 6 cm, and most preferably about 1 cm to about 4 cm when measured longitudinally across the inner diameter of the spout channel 38. _{Has a} height H jop in one embodiment of the present specification as shown in FIG. 23. _Regardless of the height H jop, the cross-sectional area of the spout port is maintained in an area of ^{about 2 cm 2} to about 20 cm ² , more preferably about 4 cm ² to about 12 cm ² , and most preferably about 5 cm ² to 8 cm ^2. Should be. _{In one embodiment of the specification, the height H jop} of the spout port 42 at the upper surface 54 or top point is preferably from the upper surface 56 of the inlet 49 to the trapway 44 as illustrated. Is also positioned at a low sealing depth x and measured longitudinally through the trap area 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, and most preferably from about 3 cm to about 9 cm, with air passing through the ejection channel 38 through the outlet port 42. It works to prevent it from happening. This distance avoids tearing in the ejection channel 38 and allows the flushing condition of the ejection channel 38 of the toilet bowl assembly 10 with fluid from the ejection flush valve assembly 70 or other flush valves before and after the flushing cycle is activated. In order to maintain, it should preferably be below the minimum level of fluid within the sump area 40.

[0259] As described above, maintaining the primed ejection channel 38, i.e., the closed ejection fluid path 1, significantly reduces turbulence and resistance to flow and improves toilet performance. Improves and allows you to use less water to start siphoning. The air in the ejection channel 38 obstructs the flow of flush water and limits the flow of the ejection portion 20. In addition, if not purged, air can be expelled through the spout port 42 and into the trapway 44, delaying the trap siphon and affecting the elimination of fluid and excrement in the bowl 30.

In order to improve the cleaning function of the bowl in embodiments of rim channels such as 110, it is also a preferred option to design the toilet assembly so that the rim is pressurized during the wash cycle. Pressurization of the rim channel 134 is preferably achieved by maintaining the relative cross-sectional area according to relational expression (I).
A _rm ＞ A _rip ＞ A _rop <6cm ² (I)
Here, _Arm 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 exit port 29. Preferably, the cross-sectional area A _jm of the ejection manifold 112 is from about 20 cm ² to about 65cm ^2, the cross-sectional area A _rm rim manifold 122 is from about 12cm ² to about 50 cm ^2. The cross-sectional area A _jm of the ejection manifold 12 is measured at a distance of about 7.5 cm downstream from the center of the ejection water washing valve inlet opening 162. Similarly, the cross-sectional area A _rm rim manifold 122 is measured by the distance downstream about 7.5cm from the center of the rim rinsing valve inlet opening 164. Gravity heads obtained from sources or in tanks by maintaining the preferred geometry of the water channel within these parameters and avoiding constrictions or bends that otherwise affect performance. Allows for a toilet bowl assembly 110 that maximizes the potential energy obtained by, which becomes crucial when a lower water volume is used in the wash cycle. In addition, by keeping the geometry of the water channel within the range of these parameters and avoiding constrictions and overly small passages in the squirt or trap, the rim in the direct-fed squirt bowl. And favorable pressurization of the ejection channel is possible, maximizing performance in both heavy removal and bowl cleaning. Preferably, since there are multiple rim exit ports that can vary in size depending on the desired design, the area of the rim exit port is intended to be the sum of all the individual areas of each such exit port. Rim. Similarly, if multiple outlet channels 118 or outlet / inlet ports are used, the outlet channel 118 or any number of ports 142 is the sum of the areas of the outlet channels or ports, respectively. In addition, to take advantage of pressurization within the rim, the ejection channel is incorporated into the relevant parts of the siphon toilet bowl design of the pressurized rim with respect to rim and ejection channel sizing and geometry of the toilet bowl. As described in US Pat. No. 8,316,475, it is preferred that when working with a pressurized rim, it is not made too small or narrowed to avoid clogging and performance degradation.

[0261] The basin area 40 of the toilet bowl 30 in embodiment 10 collects water from the rim, the ejection channel 38, and flushes and drains the excrement. The reservoir region 40 is located within the bottom portion 39 of the bowl 30 and extends for the ejection portion 20 by the inner surface 36 of the bowl 30 and by extending longitudinally from the trap inlet end 46 to the trap outlet end 50. The trap 41 is defined here, where the inlet end 46 has an opening 48 for receiving fluid from the outlet port 42. The trap outlet end 50 has an opening 52 for the fluid to exit the bowl and reach the inlet to the trapway 44. The ejection trap 41 has a sealing depth x, i.e., the top point on the upper surface 54 of the inlet to the trapway 44 and the ejection outlet port 42, as shown in FIGS. 22, 24, and 27. Has a distance from the top point on the upper surface 54 of the.

[0262] The sealing depth x of the eject trap is preferably from about 1 cm to about 15 cm, more preferably from 2 cm to about 12 cm, most preferably from 3 cm to assist in maintaining the siphon in the reservoir region 40. Measured to maintain a distance of approximately 9 cm. When the ejection trap sealing depth x is large enough, this is because the trapway can be pulled before the water level in the ejection trap 41 can be pulled below the depth at which the seal of the ejection channel 38 is broken. A state in which the ejection channel 38 is fully primed by establishing a relaxation level of fluid in the reservoir area 40 that helps ensure that the siphon is broken, thereby preventing air from advancing into the ejection channel 38. To maintain. Conversely, in some embodiments, the ejection trap sealing depth x can be equal to or less than 0 (when above the trap) and the flow velocity through the ejection flush valve assembly 70. Can still be maintained in the primed state within the ejection channel 38 and path 1.

[0263] Within the reservoir region 40, at least a portion of the inner surface 36 is tilted upwards from the outlet port 42 towards the trap inlet, thereby increasing the sealing depth x of the ejection channel 38 and washing with water. It has an inclined portion 58 that reduces the possibility of air entering the ejection channel 38 during or after the washing cycle. The sealing depth x can be further extended by forming a ejection channel 38 that temporarily sinks beneath the reservoir floor before rising to the outlet port 42 in the reservoir floor. The sealing depth x can also be increased by reducing the diameter of the outlet port 42. Preferably, the height H _jop of the spout port 42 may be reduced to form a circular, oval, or rectangular outlet, which increases the sealing depth x of the spout channel 38. While helping to maintain sufficient cross-sectional area and flow through the ejection section 20.

[0264] FIG. 20 shows an alternative embodiment collectively referred to herein as assembly 1010, except for the features of tank 1060 with separate reservoirs as described below. , Same in all other respects, with similar reference numbers pointing to similar elements within it. The tank 1060 may include at least one ejection reservoir 1068 and at least one rim reservoir 1072, the ejection reservoir 1068 being configured to deliver the ejection filling valve 1090 and fluid to the ejection manifold inlet opening 1062. Such as, may include at least one jet flush valve assembly which may be the same as in assembly 10, such that the rim reservoir 1072 delivers the rim filling valve 1092 and the fluid to the rim manifold inlet opening 1064. It may have at least one rim flush valve assembly configured, which may be the same as in assembly 110. This can be a partial transverse split portion of the tank 1060 that allows the use of one fill valve, or the tank split portion is a permanent cast preformed to make the tank into multiple reservoirs. It can be anything. If the overflow pipe is appropriately present in both the gush reservoir 1068 and the rim reservoir 1072, the overflow pipe must be operated from the rim wash fluid flow RF'rather than from the gush flush fluid flow JF'.

[0265] FIGS. 23 and 24 show another embodiment referred to herein as assembly 210 as a whole. With respect to all other points, except for the feature that the sloping wall of the basin area is composed of an upward slop or tapered position towards the entrance of the trapway 244 as described below. It is the same as the embodiment 110. The basin wall 258, as shown in FIGS. 23 and 24, extends around the basin area 240 and is designed to enclose the basin area 240. The spout port 242 is the fluid from which the fluid JF'' from the spout channel 238 enters the bowl pool area 240, thereby entering the toilet bowl from the rim through at least one rim outlet port (not shown). Positioned to merge with. The ejected fluid flow JF'' and the rim fluid flow RF'' merge at this point (with excrement and other fluids, if any) and then along the inner surface of the bowl 236, above the reservoir area. Generally, they flow together downwards, enter the reservoir area 240, enter the trapway inlet 244, and are drained through the sewage drainage channel. At least a portion of the wall 258 is tilted upwards if desired to increase the sealing depth x of the ejection channel 238, which sealing depth x is such that the air enters the ejection channel 238 during or after the washing cycle. Help prevent entry. When the sealing depth x is large enough, this causes the trapway 244 to break the siphon before the water level in the ejection trap 241 can be pulled below the depth at which the seal of the ejection channel 238 can be broken. By helping to ensure that the relaxation level of the fluid in the reservoir area 240 is established, thereby preventing air from advancing into the ejection channel 238 and the ejection manifold 212 being fully primed. To maintain.

[0266] FIGS. 25-27 show an embodiment different from that of FIGS. 16-24, which is referred to herein as assembly 310 as a whole. It is the same as embodiment 10 in all other respects, except that at least one ejection channel 338 is below the bowl reservoir area 340 as described below. The at least one ejection channel 338 is designed to extend within the bowl assembly 310 so that it is located behind the pool area wall at the rear of the internal area wall 336 and bowl 330, but the bowl 330. Internal area wall 336 and basin area wall 358 are positioned at least partially within the space defined within the generally lower toilet bowl assembly body 310. At least one ejection channel 338 passing below or below the reservoir area 340 terminates within the reservoir area wall 358, thereby positioning the outlet port 342 directly opposite the inlet to the trapway 344. do. The advantage of this structure is that its design is gravitationally capable of maintaining the capacity of the total ejection fluid JF'''and the level of fluid in the ejection channel is essentially pre-wash cycle operation. At least one ejection channel 338 remains primed more easily because it is below the water level of the fluid or flush water in the bowl both after operation and therefore to eliminate the air in the ejection channel 338. Is. By locating the route of the ejection channel 338 below the floor of the reservoir, the sealing depth x of the ejection channel 338 is determined by implementing an inclined reservoir floor as depicted in FIGS. 25 and 24. Further increasing beyond what can be achieved by morphology, the trapway breaks the siphon before the water level in the ejection trap 341 can be pulled below the sealing depth x where the seal of the ejection channel 338 breaks. It provides greater assurance, thereby preventing air from advancing into the ejection channel 338 and keeping the ejection manifold 312 in a fully primed state.

[0267] FIG. 28 shows an embodiment different from that of FIGS. 16-27, which is generally referred to herein as assembly 410. It is the same in all other respects except for the features of the upper peripheral portion 433 on the upper circumference of the bowl 430 as described below. The rim 432 has an upper perimeter portion 433 positioned around the inside of the upper perimeter of the bowl 430 so that the fluid RF'''' from the rim manifold puts excrement into the reservoir area 440. It enters the bowl for flushing, enters the toilet bowl from the ejection channel 438, and joins the drained fluid through the ejection outlet port 420. The ejected fluid flow JF'''' and the rim fluid flow RF'''' merge at this point (with excrement and other fluids, if any) and then along the inner surface of the bowl 436, the sump wall. On 458, they generally flow together downwards, enter the reservoir area 440, enter the trapway inlet 444, and are drained through the sewage drainage channel. When the sealing depth x is large enough, this means that the trapway breaks the siphon before the water level in the ejection trap 441 can be pulled below the depth at which the seal of the ejection channel 438 breaks. Helps establish a relaxation level of fluid in the reservoir area 440, thereby preventing air from advancing into the ejection channel 438 and keeping the ejection manifold fully primed. do.

[0268] In another embodiment, a rimless version of the embodiment is depicted in FIG. 28, with fluid flow from the rim inlet port to the rear of the distributor and on the rim shelf in two opposite directions on the upper perimeter portion 433. It goes around the part and travels at least partially around the inner surface of the bowl, thereby forming a cleaning action. In a preferred embodiment, the upper perimeter portion 433 may be formed to guide the wash water downward as it flows over the circumference of the bowl 430. This embodiment is similar to the assembly of FIGS. 1-13 but has a different rim shelf design.

[0269] In one embodiment of the preferred method of the invention, after serving, such as by manufacturing a toilet bowl assembly 10 as described herein, the ejector is before and after the flush cycle. It is later primed with fluid JF from at least one jet flush valve assembly 70. The methods herein can be implemented in any of the embodiments herein, including assemblies 10, 1010, 110, 210, and 310, 410, etc., but for convenience, exemplary embodiments of the method are illustrated. It will be described with reference to the assembly 10 embodied in FIGS. 1 to 13. Similar portions of the alternative embodiment may also be used in the practice of the present invention with other embodiments.

[0270] Infusing the ejection manifold 12, the ejection inlet port 18, and at least one ejection channel 38 before the flushing cycle is activated is the ejection valve flushing assembly 70 when the toilet bowl assembly 10 is attached to the mounting surface. This is done by opening the flapper or cover of the bowl to allow fluid (such as flush water) to flow through the spout port 18 and at least one spout channel 38. This priming operation is automatically performed by the first operation of the washing cycle. When the rim flush valve 80 and the ejection flush valve 70 are closed, water is maintained in the ejection channel 38 and the ejection manifold 12, and is held in place by the force exerted by atmospheric pressure on the surface of the water in the bowl 10. If any air pockets remain in at least one ejection channel 38 or ejection manifold 12 after the first flush, they are extruded during subsequent flushes to form a fully primed system.

[0271] After the initial priming of the toilet bowl assembly of the embodiments of the present specification, the user activates a flush cycle. In standard prior art toilet bowl assemblies, flush valve assemblies and overflow tubes, such as those described herein, are provided for use. Both the flush valve assembly and the flush valve cover connected to the valve are connected to the pivot arm. The pivot arm is mounted on top of the flush valve cover and is a link for attachment to a chain that can be used to lower and raise the valve cover by the actuation of any standard valve activator such as a flush handle and lever. including. Upon use, the pivot arm of the wash valve cover is attached to the overflow pipe using a standard connecting connection protruding from the overflow pipe to open and close over the inlet opening of the wash valve assembly.

[0272] When the flush cycle is initiated or activated in the present invention, the flush valve cover opens both the rim flush valve assembly and the ejection flush valve assembly, and the fluid opens at least one ejection flush valve assembly 70. Allows you to go through and enter the spout and rim. These may be opened simultaneously or through a time delay system as known in the art or developed in the future, thereby using the embodiments of wash actuated bars 75 and 1175 pointed out above. Allows optimum flow through the toilet bowl assembly 10.

[0273] Following the activation of the flush cycle and after the completion of the flush cycle, the spout inlet port 18 and at least one spout channel 38 (1) flush the depth of water in the reservoir supplied to the spout flush valve. Do not lower to the level of the inlet 71 to the ejection flush valve 70 before the valve 70 is closed, and (2) remain primed unless the seal of the ejection channel 38 is broken during or after the flush cycle. Is. If both of these conditions are met, the closed ejection fluid path 1 including the ejection channel 38 and ejection manifold 12 remains fully primed and waits for the next flush cycle.

[0274] The present invention will then be described with reference to the following non-limiting examples.
example
[0275] Table 1 summarizes the data from 20 flushes completed using three different toilet bowls. The present invention has been tested in accordance with the embodiments shown herein in FIGS. 1-3 and 29-34. The conventional toilet bowl tested required 79-82% of the flush water to be directed to the spout to achieve the desired hydraulic performance of the siphon. Toilet bowls made according to the present invention use less than 30% of the flush water directed at the spout to provide essentially comparable hydraulic performance, thereby significantly improving bowl cleaning with the remaining water. Made it possible.

[0276] Various embodiments 10, 110, 1010, 210, 310, 410 and the like herein may each benefit from modifications in the jet flush valve herein. Optional and unique features can be added to the squirt water wash valve design pointed out above to improve the operation of various embodiments. When in use, if the toilet is clogged, or for some other reason the toilet requires water to enter for various plumbing reasons, it not only releases the clog, but also climbs the ejection passage and is constantly primed. It is important to prevent backflow through the ejector valve that is closed. Backflow is not a problem with conventional toilet bowls because it is open to the atmosphere. In the primed invention, this is a problem due to the weight of the water and the existing water column in the ejection channel. One method of modifying the jet water wash valve of the present specification to withstand backflow is to provide a backflow prevention device in the jet water wash valve. Next, such a device is described with respect to a squirt water wash valve that is otherwise similar to the squirt water wash valve 70 herein.

[0277] The flush valve design described above is very effective against possible backflow of water during water ingress, but in some embodiments additional levels of protection are desired. Can be rare. By deliberately breaking the priming, that is, putting air into a closed ejection channel and opening it to the atmosphere, the possibility of backflow is greatly reduced.

[0278] FIGS. 35-38 illustrate an embodiment of a squirt water wash valve referred to herein as a squirt water wash valve 570, comprising a flapper cover 573 and a backflow prevention mechanism 574 with a holding link mechanism configuration. show. The cover 573 may be the same as the cover 15 of the valve 70 in the assembly 10. As shown, the cover 573 is fitted with a first front link mechanism mount 593 for mounting the holding link mechanism. The linkage assembly within the backflow prevention mechanism 574 is a first front link mechanism having a mounting point P for the chain C (as in FIG. 15) to connect to the actuator mechanism to allow lifting of the cover 573. Includes arm 575. Such chains can be equipped with floats as described above.

[0279] The first linkage arm is connected to the second linkage arm 576 by a hinge pin such as pin 578, but with 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 that is also pivotally mounted on the rear hinge mount 579. In use, when the flapper is lifted, the anti-backflow presser link mechanism lifts and bends freely as shown, thereby between the first and second link mechanism arms when fully opened. Form an angle of less than about 180 °.

[0280] When closed, the anti-reflux device is at a more rigid position where the chain C would remain if there was no action at point P, where the first and second linkage arms were at the junction region R. Positioning the linkage arm so that it is more aligned prevents the flow from pushing back onto the flapper cover 573 (FIGS. 37 and 38 showing the valve in the closed position).

[0281] Another embodiment of the jet water wash valve, wherein the backflow prevention mechanism 674 is a movable buoyancy poppet hat 694. 39-43 show the valve 670 in the closed position, where the poppet hat 694 is pressed into the region of the outlet 613 of the valve 670 to seal. The upward weight of the flush water on the closed valve prevents water from getting inside the valve. Backflow cannot enter the bottom of the squirt valve when the valve is closed due to pressure from within a closed squirt path called a poppet hat as described above. If a solid poppet hat (not as buoyancy) is used, a greater force is required for operation and a spring or other pulling mechanism may be used to connect the hat to the guide.

[0282] As shown in FIGS. 45-48, the jet flush valve 670, when opened, by lifting cover 673 (chain or other flush operation as described above for valve 70). Allows all flow through the valve body (such as by equipment). When the cover 673 is lifted, flush water enters the pre-primed valve and a continuous downward flow pushes out the poppet hat 694. The poppet hat 694 is preferably partially elastomeric or polymer so that it can be sealedly engaged with the valve at outlet 613. The poppet hat 694 is on a pillar 695 (which may be ribbed (or simply a circular pillar) in the cross-sectional design, as best shown in FIG. 45).

[0283] The pillar has an upper end 699 configured to have a flange 6100 on the side opposite to where it connects to the poppet hat 694. The flange acts as a stopper for the centrally positioned poppet column guide ring 699 at the bottom of the ribbed, structurally supported configuration within the valve body. As best shown in FIG. 45, a "star-shaped" configuration of ribs 696 extending outward from the central hub 697 is shown. The opening 698 penetrates the hub and allows the poppet column to easily pass upwards when the valve is in the closed position (see FIG. 43). When opened, the column moves downward under flow pressure until the flange 6100 comes into contact with the guide ring 699 in the fully extended position, whereby the poppet hat 694 does not unnecessarily obstruct the flow. ..

[0284] Further embodiments of the backflow prevention jet flush valve 770 are shown in FIGS. 49-56. In this embodiment, the backflow prevention mechanism 774 is a hook 7101. The hook 7101 is fitted onto the front end of the cover 7102 of the squirt water wash valve 770, which is different from the other covers in other embodiments as described below. The hook 7101 has an extension hook arm 7103 that contacts the catch 7104 positioned on the outside of the ejection valve body. The hook arm 7103 must have some gap g between it and the opposite surface 7105 of the catch 7104, which must be as small as possible to close tightly to prevent backflow. However, the hook cannot easily pass through when the valve is opened and should not be small enough to rotate around the catch 7104, preferably the void is from about 1 mm to about 5 mm.

[0285] A unique feature of the jet water wash valve 770 other than the backflow prevention mechanism 774 is the cover 7102. The cover is not just a liftable flapper cover, but a "peeled" cover. This design allows the ejection valve to open from the front of the cover along the edge towards the rear of the cover. This structure is formed to be flexible or partially flexible. Elastomers or other flexible polymers (such as flexible silicone or polyvinyl chloride) or other similar materials accepted for piping and having piping ratings may be adapted to the flexible portion. By peeling, the valve cover can be peeled upwards along the edge 7105 of the front 7106 of the valve cover 7102 towards the argument 7107 so that water is present above and below the cover. Helps reduce operating force. Applicants can use a flexible or semi-flexible cover to allow peeling along the edges to achieve a good automatic priming aspect for squirt valve and closed squirt paths. I found it useful to do. Rigid flapper covers, such as hard covers with standard disc-shaped seals, can make automatic priming more difficult. By peeling and slowly opening, the valve 770 can allow all of the trapped air to escape. It is preferred that at least about 50% of the cover 7102 is flexible in the front 7106 of the cover, which is half back towards the rear 7107 of the cover. The rear half of the cover does not have to be flexible.

[0286] In order to activate the peeling mechanism and lift the hook backflow prevention mechanism, the first chain C1 works with the flushing actuating mechanism of the toilet bowl to lift and lift the hook 7101 when the valve is open. Later, the front 7106 of the cover is peeled off and lifted upward. When this is lifted, the hinged arm 7108 (which can be formed using any suitable hinge / hinge connection material and structure as pointed out above for embodiment 570) is bent upwards. The hinged arm 7108 is mounted on an optional cover plate 7110 (which may be metal, polymer, or elastomer) using a hinge mount 7109 to help remove the front portion 7106 of the cover 7102 upwards. Suitable water wash actuators can also be used and / or modified to connect to chains C1, C2. After C1 lifts the front part of the cover upward and peels it off at the end 7105, the rear part of the cover is lifted. A separate float attachment, which may be a second chain C2, which can have a float as described above, is provided. Other modifications of the float attachment for connecting the float to the rear portion of the cover may also be used, which are described in more detail below and include float assemblies as shown in FIGS. 88-90. include. Strings, cords, ropes, stainless steel cables, rigid rods, or wires can also be used with floats as an alternative embodiment of float attachments.

[0287] The interior of the valve 770 also preferably has a "star" structure using a structure formed from ribs 796 linking the body of the valve to a central hub 797 extending through an opening 798. The flow can easily pass through the rib structure, which helps support the weight of the flush fluid on the valve by extending radially over the body of the valve. The flapper has twice the force required to open, so the support is designed to aid in operation and also to allow air to escape using baffles or ribs molded as shown. Is. The number of ribs can affect the flow if there are too many ribs, too large ribs, or if they are shaped inconveniently.

[0288] FIGS. 64-68 are the same embodiment of the valve 770, with an optional overflow pipe 791 built onto it. The overflow pipe 791 includes an upper housing 769 that may allow air to enter and escape for incorporating any of the various standard valves V into it as another check valve for backflow through the ejection valve. .. The valve can be manually turned to the open position to break the priming and allow water to enter without backflow. Breaking the priming may also be desirable in other situations such as maintenance work or pre-repair. Suitable valves, such as ball valves, disk valves, or the like, may also be incorporated therein. The valve V is shown schematically in the partial cross-sectional view of FIG. Housing 769 is optional and other direct connection valves may be used. The valve can then be manually reset to the working position by the user and the toilet bowl can be returned to the primed state. Preferably, the valve can incorporate a check valve, which automatically opens when a positive pressure exceeds that encountered during a normal wash cycle occurs within the closed ejection channel. Keeps open, allowing air to enter the channel and break the priming. The check valve can then be manually reset to the working position by the user and the toilet bowl can be returned to the primed state. Most preferably, the check valve returns to the closed position with a delay of about 5 to about 60 seconds without the need for manual intervention on the part of the user. This can be done electromechanically or mechanically, for example, by a flapper type valve with a liquid damping hinge.

[0289] FIGS. 58 and 59 show the same embodiment 870 as that of the jet flush valve 770, which has the same reference number in it pointing to the same part, whereas in the flush valve 870 a star-shaped configuration of the support structure. However, it differs in that it has eight ribs instead of the four shown in the valve 770. The number and deformation of such ribs have been modified to provide a variable angle of structural support without unnecessarily obstructing the flow through the valve, to maximize and smooth air clearance. What you get will be understood by those of skill in the art.

[0290] FIGS. 60-63 show an embodiment of a flush valve 970 having a backflow prevention mechanism 974 with a holding link mechanism configuration similar to that of the valve 570, wherein the embodiment 970 has a single downward direction. The third link mechanism arm is different in that it includes a bridge structure 9111 that increases in width as it extends downward. The bridge structure 9111 acts as a third linkage arm, but divides the downward resistance towards the hinged arm 9108. Such a hinged arm 9108 is attached at the hinge mount 9109 and acts to impart the cover 9102 the ability to "peel" upwards as in embodiments 770 and 870. The anterior portion of the backflow prevention mechanism 974 includes first and second hinged linkage arms 975, 976 similar to those of embodiment 570. The second linkage arm is linked to the top of the bridge structure 9111 by a standard hinge connection, which in turn engages the rear of the hinged arm 9108 by the hinge structure 9112. The first linkage arm is connected to the front portion 9106 of the cover 9102 by a hinge mount 993. The chain (not shown) may be attached to point P to lift the front of the cover 9102 as described in embodiment 570, but unlike embodiment 570, cover 9102 is the embodiment 710. As flexible as the cover 7102 in, it can therefore be peeled upwards. An additional chain is used to hold the float in embodiment 710 and raise the rear half of the cover 9102 at the position of the grommet 9113 or similar structure as shown for chain C2 in embodiment 710. Can be done. Grommets 9113, or similar structures, are also used to secure float attachments, including float assemblies, strings, cords, ropes, stainless cables, rigid rods, or wires as shown in FIGS. 88-90. Can be used.

[0291] FIGS. 69 and 70 show an embodiment of the ejection valve assembly 770, 870, and another embodiment of the ejection valve assembly 1170 similar to 970. This embodiment may be used without a backflow prevention mechanism or may include a backflow prevention mechanism as shown in any of the above embodiments 570, 670, 770, 870, 970 and the like. As represented in embodiment 770, the solution to overcome the additional force required to open the primed squirt valve is to include a gradual opening valve, where the valve section is "stripping". It opens "taken" and allows some water to enter the spout, thereby equalizing the pressure before the valve is fully opened. One or more valve assemblies are preferably configured such that at least the ejection valve assembly 1170 has a valve cover 1173 and a valve body 1121 and is "stripped" open. It is also understood that multiple valve assemblies in a single tank, including rim valve assemblies, can have similar configurations. Although valve assemblies are described herein for use with siphon toilets, it is also understood that valve assemblies can also be used with flush toilets, including flush toilets.

[0292] FIGS. 73-75 are similar to cover 7102 of embodiment 770 and show such an embodiment of valve cover 1173, preferably having a seal 11170 and a rigid cover 11180. The rigid cover 11180 can preferably bend with the seal 11170 to gradually open the valve cover 1173. The rigid cover 11180 may have a peeling section 11182 and a lifting section 11183 that are preferably transversely separated from each other. The peel section 11182 has at least one hinged mount 11108 that is preferably configured to connect to the lift section 11183. The configuration of the connection between the hinged mount 11108 and the lifting section 11183 is preferably a rotatable connection. Such configurations for rotatable connections are described in more detail below and are shown in FIGS. 73 and 74.

[0293] The rigid cover 11180 may operate similarly to the cover plate 7110 of embodiment 770 described above. Preferably, the trailing edge 11185 of the peel section 11182 and the leading edge 11186 of the lift section 11183 are substantially parallel to each other and with respect to the central longitudinal plane defined by the VP and VP'of the valve cover 1173. It is virtually vertical. There may be a transverse separation TS between the edges 11185 and 11186. _{The distance d TS} from the trailing edge 11185 of the peel section 11182 to the leading edge 11186 of the lift section 11183 is preferably 10 mm to 20 mm, but this distance may depend on the size of the valve cover 1173. As long as the peeling section 11182 can be lifted from the valve body 1121 by a certain distance without the lifting section 11183 moving, any separation distance d _TS , even if there is no separation, is intended and each section is in the process. There is sufficient clearance to bend the seal 11170 without interference.

[0294] Chain C1 may be used to connect the peeling section 11182 of the rigid cover 11180 to the wash actuation bar 1175. When the wash actuation bar 1175 is lifted, the peeling section 11182 of the valve cover 1173 can be lifted from the valve body 1121. The peel section 11182 may be associated with the lifting section 11183 through the hinged arm 11108. The hinged arm 11108 is preferably immovable at the connection with the peeling section 11182 and is configured to connect to the lifting section 11183 with a rotatable connection. The hinged arm 11108 may be integrally formed with the peeling section 11182 during the forming process and may preferably have two pegs 11115 extending from the outside of each of the hinged arm 11108. The pegs 11115 are preferably cylindrical and have a size that can be inserted into slot 11116 on the hinged mount 11109. Although two hinged arms 11108 are preferred and are shown in the figure, it is understood that one or more hinged arms 11108 may be used. The elastically deformable support member 11117 may be placed between the two preferred hinged arms 11108. An elastically deformable support member 11117 is not required as the hinged arm 11108 can have a size and shape that is elastically deformable by itself.

[0295] The hinged arm 11108 preferably connects to the lifting section 11183 through the hinged mount 11109, and the connection is rotatable around a straight line parallel to the leading edge 11186 of the lifting section 11183. Each hinged mount 11109 preferably has a longitudinally extending slot 11116 with an oval shape, but it is understood that any shape, such as rectangular, circular, or hexagonal, is possible. .. The peg 11115 on the hinged arm 11108 can be inserted into slot 11116 by using the elastic deformation of the elastically deformable support member 11117. The oval shape allows the pegs 11115 not only to move rotatably, but also longitudinally into each slot 11116. This movement allows the peeling section 11182 to optimally interact with the lifting section 11183. It is understood that any rotatable connection can be used to connect the hinged arm 11108 to the lifting section 11183, and no longitudinal movement is required. Possible rotatable connectors are hinged type fittings such as protrusions on one element that snap into the opening of the other element, or pins inserted into the openings located within each element. May include the use of. Other types of connections that can rotate around the same axis, including ball / socket type fittings, are also contemplated.

[0296] As the peeling section 11182 continues to lift, the hinged arm 11108 preferably rotates around the connection with the hinged mount 11109 so that the peeling section 11182 does not move the lifting section 11183 over a short period of time. Allows lifting from the valve body 1121. After the peel section 11182 has been lifted to a sufficient angle by the chain C1 and the wash actuation bar 1175, the hinged mount 11109 preferably acts on the lift section 11183 to open the lift section 11183 of the rigid cover 11180. The entire valve cover 1173 is completely lifted from the valve body 1121. The float F can also be attached to the valve cover 1173 by using the chain C2, the float assembly 11270 described below, or other connecting device. The float can provide buoyancy to reduce the force required to open the valve cover 1173 and / or control the time the valve closes through a drop in the water level in the tank during washing. The lower the position of the float along the chain, the more likely it is that the valve will be delayed in closing and the amount of flushing will increase.

[0297] Assembly kit 1100 with a first valve assembly, a second valve assembly, and a flush actuated assembly, without additional tools, the second valve assembly having a float attachment in the form of a float assembly 11270. Is shown in FIG. 88. The float assembly 11270 includes a float F and a float connector 11280 configured to connect the float to the second valve assembly 1170. The float attachment according to this modification can be used in place of the chain C2 to connect the float to the second valve assembly. 89-90 show an enlarged view of a second valve assembly 1170 with a float 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 float connector 11280 may be rigid or semi-rigid, preferably made of a polymeric material. However, the float connector may be made of a material having an appropriate density that does not interfere with the operation of the float F when applying buoyancy to the valve cover 1173. The length of the float connector l _FA can be varied to adjust the speed at which the valve cover opens fully. The length l _FA may be in the range of about 4 cm to about 14 cm.

[0298] The float connector 11280 has a first end 11271 and a second end 11272. The float F is secured on the first end 11271 of the float connector 11280. The second end of the float connector 11272 is second by using a clip 11273 that snaps onto a raised bar 11274 located on the lift section 11183 of the second valve assembly 1170. It is hinged and connected to the lifting section 11183 of the valve assembly 1170. Clip 11273 allows the float 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 that is the center of rotation of the valve hinge 11275. Rotating connections, such as pins, ball fittings, or other known rotating or hinged connections that are inserted through holes in one or both elements, rotating connections are valve hinges 11275. It is understood that the float assembly can be used to connect to the lifting section of the valve assembly so that it can rotate around an axis parallel to the axis that is the center of rotation of the.

[0299] The first end 11271 of the float connector may include a clasp 11276 for holding the float F. The clasp 11276 is somewhat elastically deformable so that the force that attempts to return the clasp to a stationary position when the float is inserted into the opening holds the float F in place by friction. When used with a standard float, _{the clasp opening at its minimum height h SC} is preferably about 0 cm to about 4 cm high in the stationary position, about when the float is inserted into it. The height is from 1 cm to about 5 cm (float height). The highest height h _TC of the clasp opening is about 2 cm to about 6 cm both at rest and when the float is inserted in. The bottom of the clasp may have a flat platform 11277 of similar shape when the bottom of the float and the top of the clasp 11278 can be curved, whereby the entire first end 11271 is shaped like a cotter pin. Take. The elastically deformable nature of the clasp allows the use of a variety of different floats so that the buoyancy of the valve cover is adjustable and, if necessary, makes it easy to replace the floats. ..

[0300] After the peeling section has been lifted to the point where the upward force increases on the lifting section, the float assists with a small force to fully open the lifting section. When the valve opens, the connection between the second end 11272 of the float assembly 11270 and the lifting section 11183 allows the float F to remain in a vertical position through the opening of the valve cover. One or more stoppers 11279 may be placed on either side of the clip 11273 so that the float assembly 11270 does not fall completely with the water level when the water level drops below the level of the float F. It will be appreciated by those skilled in the art based on the present disclosure that stoppers are not required for the float to function properly, but can prevent the float assembly from interfering with the operation of other parts of the valve assembly. Let's do it.

[0301] The second or ejector valve assembly is described as having a float attachment, whereas the ejector valve assembly and / or the rim valve assembly may accommodate the float attachment, either or both. The valve assembly can behave similarly.

[0302] FIGS. 76 and 77 are of the seal 11170 which is used with the rigid cover to prevent liquid from entering the spout at undesired times and which can move with the rigid cover 11180 to gradually open the valve cover 1173. An embodiment is shown. The seal 11170 may have a sealing surface 11171 and a locking surface 11172. The locking surface 11172 may include a plurality of locking lugs 11173 that may assist in fixing the seal 11170 to the rigid cover 11180, as shown in FIGS. 73-75. The seal 11170 is preferably positioned such that the peeling section 11182 and the lifting section 11183 engage with each other facing each other. The seal is preferably attached to the rigid cover 11180 using only a plurality of locking lugs 11173 or in combination with an adhesive or other fixing method. The locking lug 11173 may serve as an additional feature that helps prevent the force of liquid flow from peeling the seal 11170 from the rigid cover. The use of locking lugs 11173 may be preferred, but it is understood that adhesives or other fixing methods can also be used alone.

[0303] The locking lug 11173 may be useful in a mode of detachment of the valve cover 1173. The arrangement configuration of the locking lugs 11173 on the seal 11170 is such that one or more locking lugs 11173 are disposed within the peeling section 11182 and one or more engagements, as described in more detail below. It may be possible to allow the stop lug 11173 to be placed within the lifting section 11183. When the peel section 11182 is lifted, the force may be applied to the seal 1170 in the opposite direction of movement, which pulls the seal 11170 away from the rigid cover 11180 and closes the valve for a longer time than desired. May allow you to leave. Delays can affect the timing between the opening of the rim valve and the opening of the ejection valve, and / or may reduce the benefit of opening the peel section before the lifting section. The locking lug 11173 preferably lifts from the valve body 1121 and applies a counter-acting force to the liquid on the seal 11170 that should be sufficient to maintain proper timing for the valve to open.

[0304] A plurality of locking lugs 11173 may be arranged and configured around the locking surface 11172 and may be positioned to engage with a plurality of corresponding openings 11188 within the rigid cover 11180. A preferred arrangement configuration may include, for example, three rows of locking lugs 11173, with one or more locking lugs 11173 arranged in each row. Preferably, the first row 11174 may have at least one locking lug 11173 configured to connect to the peeling section 11182, the second row 11175 connecting to the front of the lifting section 11183. The third row 11176 may have at least one locking lug 11173 configured to connect to the rear of the lifting section 11183. It may be a thing. The configuration of the lug 11173 connections is such that the size and shape of each lug 11173 makes it relatively easy to insert the lug into the opening, but makes it more difficult to remove the lug from the opening. .. The configuration of the connection between the locking lugs and their respective detachment and lifting sections may depend on the placement and shape of the particular locking lugs. Preferred specific features of the configuration are described in more detail below.

[0305] The particular placement of each locking lug depends on the size and / or shape of the valve cover 1173. Rows 11174 to 11176 may be located at various distances from the central vertical longitudinal plane VP through the valve cover 1173 and the point CP located on the leading edge of the seal 11170 on the VP'. Preferably, for standard valve cover sizes, the first row 11174 may _{be located at a distance d 1R} from about 5 mm to about 15 mm from the point CP and the second row 11175 may be located at the point. _{It may be located at a distance d 2R} of about 40 mm to about 60 mm from the CP, and the third row 11176 may be located at a _{distance d 3R} of about 60 mm to about 80 mm from the point CP. This configuration should allow the seal 11170 to be adequately secured to the rigid cover 11180 and also allow the peeling section 11182 and lifting section 11183 to open at different times.

Other configurations for the plurality of locking lugs 11173 are also contemplated. For example, only a single row of locking lugs may be used, where the row is preferably located about 5 mm to about 30 mm from the point CP. Such an arrangement allows the lugs to secure the seal to the rigid cover when the peel section is being lifted. The single row may also be located about 30 mm to about 90 mm from the point CP. It is also understood to use two rows of locking lugs, where one row is located about 5 mm to about 30 mm from the point CP and the second row is about 35 mm to about 90 mm from the point CP. Placed in place. Generally, not using any rows, which are located between about 5 mm and about 30 mm from the point CP, and using one or more rows can be any combination of about 35 mm to about 90 mm from the point CP. It is understood to include not using any of the columns arranged in place, using one or more columns, and not using any of the columns of the lug. The placement of the lugs 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 lifting section 11183.

[0307] Preferred shapes for each of the locking lugs 11173 may include a head portion 11190 and a neck portion 11191. The head portion 11190 is preferably slightly larger than the neck portion 11191 so that the seal 11170 is adjacent to the rigid cover 11180 when the head portion 11190 is inserted into the corresponding opening 11188 within the rigid cover 11180. It is locked at the position where it is used. The head portion 11190 preferably has a conical shape with a generally rounded top surface, and the neck portion 11191 preferably has a generally cylindrical shape. The shape of the locking lug 11173 is described to have a generally circular cross section cut parallel to the seal based on the preferred shape described above, but the head portion 11190 and / or the neck portion 11191. It is understood that this cross section of can have any shape such as oval, triangular, square and so on. Other shapes with a circular cross section, such as a spherical head, are also understood.

_{[0308] The distance d TH} measured along the cross section of the bottom surface 11192 of the head portion 11190 is from _{the distance d TN} measured along the cross section of the top surface 11193 of the neck portion 11191. May be large. In addition, the circumference of the bottom surface 11192 of the head portion 11190 is preferably larger than the circumference of the corresponding opening 11188 in the rigid cover 11180 such that the head portion 11190 performs a locking function with respect to the rigid cover 11180. The circumference of the top surface 11193 of the neck 11191 is preferably smaller than the circumference of the opening 11188 in the rigid cover 11180 so as to fit into the opening 11188. The neck 11191 can also be made of a compressible material that deforms when inserted into the opening 11188. In such a case, it is possible that the circumference of the top surface 11193 of the neck portion 11191 is larger than the circumference of the opening 11188 in the hard cover 11180. In addition, if a compressible material is used throughout the neck or locking lugs, the head and neck will be single, as the neck section will deform and provide sufficient locking when inserted into the opening. It can also be shaped into a cylinder, or any other shape with a uniform cross section.

[0309] The preferred shape for the locking lug 11173 in the first row 11174 and the second row 11175 is a generally flat surface along the side of the valve cover 1173 facing the central vertical longitudinal plane VP-VP'. 11194 may be included. The flat surface 11194 may extend along both the head portion 11190 and the neck portion 11191. The flat surface 11194 on the locking lug 11173 is optional and can be used to aid mounting, but is not an essential element of the seal 11170.

[0310] The dimensions of each head portion 11190 and neck portion 11191 of the lug 11173 may be uniform, but one or more lugs 11173 may have one or more uniform dimensions. As shown in FIGS. 76 and 77, one or more of the lugs 11173 may have a head portion 11190 and / or a larger neck portion 11191 that is larger than the other locking lugs 11173. Preferably, the locking lugs 11173 located in the third row 11176 are larger than the other locking lugs 11173 and have a different shape than the other locking lugs 11173. For example, in FIGS. 76 and 77, this locking lug does not share the flat surface 11194 with other locking lugs 11173. The different sizes and shapes of the locking lugs in the third row allow for a more secure connection between the seal 11170 and the rigid cover 11180 due to the large size and continuous contact with the top of the opening. Can form. The one or more locking lugs 11173 may have different shapes, and all of the locking lugs 11173 may have uniform dimensions and / or shapes.

[0311] The method of locking the seal 11170 to the rigid cover 11180 preferably comprises passing each locking lug 11173 through and into the corresponding opening 11188 of the rigid cover 11180. The head portion 11190 should be elastically compressed when inserted through the opening 11188, thereby expanding and performing a locking function after passing through the opening 11188. All locking lugs 11173 may be inserted into each opening 11188 at the same time, or one or more may be inserted into each opening 11188 at a time. Before inserting the locking lugs 11173 into the respective openings 11188, an adhesive may be appropriately applied to the locking surface 11172 of the seal 11170 and / or the adjacent surface of the hard cover 11180. When the seal 11170 is locked to the hard cover 11180, the head portion 11190 of the locking lug 11173 may be located on the opposite side of the hard cover 11180 from the locking surface 11172, and the neck portion 11191 is of the hard cover 11180. It may be arranged in the opening 11188, and the locking surface 11172 may be aligned and connected to the head portion 11191. It is also not necessary to use the locking lug 11173 with the head portion 11190 and the neck portion 11191 as shown in the figure for embodiment 770, where the lug 11173 corresponds to the opening of the rigid cover 11180 for alignment purposes. It may have only the neck portion 11191 for insertion into the portion 11188. It is also contemplated to use a seal 11170 that is attached to the rigid cover 11180 using only adhesive without locking lugs.
