Description

  The present invention relates to the field of toilets for the removal of people and other waste. The invention further relates to the field of toilets that operate to effectively flush without having a rim.

CROSS REFERENCE TO RELATED APPLICATIONS This application is a U.S. Provisional Patent Application No. 119 of US Provisional Patent Application No. 61 / 603,232, filed February 24, 2012, the entire disclosure of which is incorporated herein by reference. Claims the benefit of Article (e).

  Various toilets for removing excrement such as human excrement are well known. Most toilets are powered by gravity and usually have two main sections: a tank and a toilet bowl. The tank and toilet bowl are separate parts that combine together to form a toilet system (commonly referred to as a two-piece toilet) or a single unit (usually referred to as a one-piece toilet) ) Can be combined.

  Typically, the tank located above the rear of the toilet bowl begins to flush waste from the toilet bowl into the sewer and contains water used to refill the toilet bowl with fresh water. Not all toilets have a tank fitted with an in-line flush mechanism, as in many commercial buildings, for example. When the user desires to flush the toilet, the user activates the flush mechanism. Such a flushing mechanism may be located in the rear wall of a toilet that does not have a tank, placed above the rear of a wall-mounted toilet, or positioned in a tank. When the flush lever is actuated, for example, when the handle on the outside of the tank is pushed down, a flush cycle is started. As a typical example, when such a flush lever is pushed down, this moves a chain or lever inside the tank that operates to lift and open the flush valve, allowing water to flow from the tank into the toilet bowl. And start flushing the toilet.

  There are three general functions that most toilets are designed to include within a particular flush cycle. The first function is the removal of solids and other wastes into the drain. The second function is the cleaning of the toilet bowl to remove any solid or liquid waste deposited or adhered to the toilet surface, and the third function is the use of relatively clean water. The amount of pre-wash water in the toilet bowl is changed so that it stays in the toilet bowl when it is not.

  In order to achieve the three functions described above, the toilet toilet design employs a general overall structure consisting of a toilet bowl, a trapway, and a rim. The toilet bowl serves as a reservoir for pre-wash water and a collection part for excrement. The trapway fluidly couples the toilet bowl to the drainage channel and blocks back flow of sewage gas. Usually, the rim portion formed as a hollow member capable of carrying flush water is washed by dispersing water around the surface of the toilet bowl.

  Cleaning is sometimes a problem for toilets with this standard structure, which is good cleaning below the rim, even if the toilet has a good flush design to wash the main toilet bowl of the toilet bowl This is because it is difficult to realize the action. The rim outlet port is typically located on the lower surface of the rim and directs the flow downward and outward toward the toilet bowl wall. Normally, there is no mechanism for directing this water to clean the rim itself. Dirt, human feces, and bacteria can accumulate on and below the rim, where only manual cleaning serves to remove it. Since the underside of the rim is not easily visible to toilet bowl cleaners, potentially harmful substances can remain below the rim for an extended period of time. In fact, studies have shown that Salmonella can survive below the toilet rim for up to 4 weeks, even if cleaning is attempted. J. et al. Barker et al., J. MoI. Appl. See Microbiology 2000, 89, 127-144.

  A second related problem presented by the standard toilet bowl-trapway-rim structure of the toilet bowl is its effective use as a urinal for an upright male. The standard structure has a rim protruding from the surface of the toilet bowl, which reduces the area available for receiving urine flow. As a result, the toilet rim of a standard structure is more prone to soiling due to deviating flow. Further, as described above, normally, a mechanism for automatically cleaning the rim portion itself during the water washing cycle is not provided. In such situations, manual cleaning is required.

  A third problem presented by the standard toilet bowl-trapway-rim structure of toilet bowls is related to the complexity of manufacturing such an outline in the melted porcelain. The protruding rim portion requires a more complex configuration of the mold for forming the toilet bowl outline. The undercut section of the rim portion (ie, the joint between the lower surface of the rim portion and the toilet bowl) cannot be formed from a single die without locking the die in place after casting. The desired contour can be assembled and disassembled by (1) casting the rim as a separate object from the toilet bowl and sticking the two together, or (2) forming the toilet as a single object It must be formed by utilizing a set of loose molds, which can also remove the mold that forms the undercut of the toilet bowl and rim.

  Gravity toilets can be further classified into two general types: wash-off and siphon. A wash-out toilet allows the water level in the toilet bowl to remain relatively constant at all times. When the flush cycle begins, water flows from the tank and into the toilet bowl. As a result, the water level rises quickly and excess water overflows the trapway weir and carries liquid and solid waste with this water. At the end of the flush cycle, the water level in the toilet naturally returns to the equilibrium level determined by the weir height.

  In a siphon toilet, the trapway and other hydraulic channels are designed so that siphoning is initiated within the trapway when water is added to the toilet bowl. The siphon tube itself is an inverted U-shaped tube that pulls water from a toilet bowl to a drain pipe. When the water wash cycle begins, water flows into the toilet bowl and overflows the weir in the trapway faster than it can exit the outlet to the sewer. Sufficient air is eventually removed from the descending legs of the trapway to begin siphoning, which in turn draws the remaining water from the toilet bowl. The water level in the toilet bowl when the siphon action is broken is consequently much lower than the height of the weir, and at the end of the siphon flush cycle, the protection “sealing” against the original water level and sewage gas backflow is restored. In order to establish, it is necessary to provide a separate mechanism for replenishing the toilet bowl.

  Siphon and wash-off toilets have inherent advantages and disadvantages. Siphon toilets tend to have smaller trapways that can result in clogging due to the requirement that most of the air must be removed from the descending legs of the trapway to initiate siphoning . Although wash-off toilets can function with large trapways, the 100: 1 dilution level required by plumbing regulations in most countries (ie 99% of the pre-wash volume in the toilet bowl is It may usually be necessary to reduce the amount of pre-wash water in the toilet bowl to achieve (which must be removed from the toilet bowl and replaced with fresh water). This small amount of pre-washing appears as a small “water spot”. The water spot or surface area of the pre-wash water in the toilet bowl plays an important role in maintaining the cleanliness of the toilet. A large water spot increases the likelihood that excretory material will come into contact with water before it contacts the ceramic surface of the toilet. This reduces the adherence of the waste material to the ceramic surface and makes it easier for the toilet to clean itself through the water wash cycle. Therefore, wash-off toilets with small water spots often require manual cleaning of the toilet bowl after use.

  Siphon toilets have the advantage of being able to work with a greater amount of pre-wash water and a larger water spot in the toilet bowl. This is possible because the siphoning action draws most of the pre-wash water volume from the toilet bowl at the end of the wash cycle. When the tank is refilled, a portion of the refill water is directed into the toilet bowl to return the pre-wash volume to its original level. In this way, the 100: 1 dilution level required by many plumbing regulations is achieved even when the starting amount of water in the toilet bowl is significantly higher than the flush water leaving the tank. In the North American market, siphon toilets are widely accepted and are now considered the standard accepted toilet form. In the European market, wash-off toilets are still more accepted and popular, but all versions are common in the Asian market.

  Gravity siphon toilets can be further subdivided into three general types depending on the design of the hydraulic channel used to achieve the flushing action. These types are a non-spout type, a rim part spout type, and a direct spout type.

  In a non-spout toilet, all flush water exits the tank and enters the toilet entrance area, flows through the main manifold and enters the rim channel in the standard rim. The water typically exits through a series of holes in the lower portion of the rim as pointed out above. A relatively high flow rate is required to flood the trapway weir with water fast enough to displace the air in the descending leg sufficiently to start the siphon action. A non-spout type toilet generally has a sufficiently good performance with respect to cleaning a toilet bowl, but a mechanism for cleaning the surface of the rim portion itself is not usually provided. Mass removal is relatively inadequate, which is an insufficient and turbulent supply of water to the trapway, thereby sufficiently filling the descending leg of the trapway and initiating strong siphoning This is because it becomes more difficult. As a result, non-spray toilet trapways are generally smaller in diameter and include bends and constrictions designed to impede water flow. Without a smaller size, bend, and constriction, strong siphoning is not achieved. Unfortunately, the smaller size, bends and constrictions result in poor performance and frequent clogging with large amounts of waste removal, a condition that is extremely unsatisfactory for the end user. Such clogging phenomena can also lead to cleanliness problems if the excrement has the opportunity to stay in the toilet bowl or obstruct the trap way before it is easily washed or cleared.

  Toilet designers and technicians have improved the removal of large amounts of waste in siphon toilets by incorporating “siphon eruption”. In the rim spout toilet bowl, as pointed out above, flush water exits the tank, flows through the manifold inlet region, enters the hollow rim channel through the main manifold. Water is also distributed throughout the circumference of the toilet bowl through a series of holes located under the rim. The remaining part of the water flows through the ejection channel arranged in front of the rim part. This squirt channel connects the rim channel to a squirt opening located in the toilet bowl. The spout opening is sized and arranged to send a strong water stream directly to the trapway opening. As water flows through the spout opening, it serves to fill the trapway more efficiently and quickly than can be achieved in a non-spout toilet. This more vigorous, faster flow of water to the trapway allows the toilet to be designed with a larger trapway diameter and fewer bends and constrictions, which Compared with non-spout type toilets, it improves performance in removing large amounts of waste. Although a smaller amount of water flows out from the rim part of the rim part type toilet, the water flowing through the rim part channel is pressurized by the upstream stream of water from the tank, so the toilet flushing function is better . For this reason, water can exit the hole in the rim portion with higher energy, and can more effectively perform toilet cleaning work. Nevertheless, the presence of rim designs with protruding surfaces still leaves clean and hygienic issues and requires manual cleaning. However, as described above, there is usually no mechanism for cleaning the surface of the rim portion itself.

  Rim-jet toilets are usually superior to non-spout types, but long passages where water must travel through the rim to the jet opening dissipate and waste much of the available energy. Direct ejection toilets improve on this concept and can provide better performance with respect to the removal of large amounts of waste. In a direct jet toilet, flush water exits the tank and flows through the toilet inlet and main manifold. At this point, the water is divided into two parts. One part flows through the rim inlet port to a hollow rim channel (designed similar to that noted above), where the main purpose of the rim channel is to achieve the desired toilet flushing That is. The second part flows through the spout inlet port to a “direct spout channel” that connects the main manifold to a spout opening in the toilet bowl sump. The direct ejection channel can take a variety of different forms, sometimes it is unidirectional around one side of the toilet, or a symmetrical channel travels down on both sides and exits the manifold "Double supply" that connects to Similar to the rim spout toilet, the spout opening is sized and arranged to send a strong water stream directly to the trapway opening. As water flows through the spout opening, it serves to fill the trapway more efficiently and quickly than can be achieved in a non-spout toilet or rim spout toilet. This more vigorous, quicker flow of water to the trapway allows the toilet to be designed with an even larger trapway diameter and minimal bends and constrictions, which Furthermore, the performance in removing a large amount of waste is improved as compared with non-spout type and rim-part spout toilets. Such an improvement results in better water washing, but the cleanliness of the rim portion of the rim portion itself remains a problem.

  Some inventions have been aimed at improving the performance of siphon toilets by optimizing the direct jet concept. For example, in US Pat. No. 5,918,325, siphon toilet performance is improved by improving the shape of the trapway. In US Pat. No. 6,715,162, performance is improved by using a flush valve with a radius built into the inlet and an asymmetric flow of water into the toilet bowl.

  As pointed out above, direct jet toilets provide better flushing, but can improve the toilet's cleaning ability. Due to the hydraulic design of the direct jet toilet, the water entering the rim channel is not pressurized. Rather, it flows into the rim channel only after the ejection channel is filled and pressurized. As a result, the water exiting the rim portion has very low energy, and the toilet flushing function of the direct ejection toilet is usually inferior to the rim portion ejection type and the non-ejection type. This region is particularly affected when the amount of flush water is reduced.

  This problem was addressed in US 2010/0186158 Al, which describes a toilet that splits the flow between the lower ejection portion and the rim portion, resulting in a swirling effect. In this rim flow, the incoming water is divided so that it flows evenly from side to side in the rim, some of which are directed to various "slots" in the rear of the rim, and these slots Blows out tangentially into the toilet, improving cleaning and flushing action.

  US Patent Application Publication No. 2009 / 0241250Al also enables pressurized rims and enhanced siphoning to enhance washing and suitable for use with small amounts of water that meet current environmental standards for water use. It proposes to solve the problems of the prior art by providing a direct supply jet shape. However, this does not address the issue of rim cleanliness.

  WO 2009/030904 Al teaches a toilet that does not have a rim on the upper surface of the toilet with a protrusion for directing water through a series of holes. Instead, all of the tank flush water enters the toilet in the main manifold and then proceeds into two opposing inlets in the rear portion of the upper part of the toilet. A shelf-like ridge or water guide is formed in the toilet bowl, on which the water that enters the toilet bowl travels approximately horizontally until it is closer to the front of the bowl, where the water is directed toward the bottom of the toilet bowl Proceeding almost vertically, creating flush columns. The edge or wave guide can be tilted downward at an angle that causes a portion of the flow to flow out of the guide longitudinally for cleaning action.

  GB 2431937 shows a modified rim that narrows towards the front of the toilet, which can minimize some of the cleaning problems, and the water passes through the rear of the toilet and the rim Enter through the curved opening in the section, thereby entering the toilet bowl in a circular or curved manner. The toilet bowl has an inner surface on the interior of the toilet bowl that creates a more circular flow for cleaning.

  The design of gravity flush toilets in today's market has increased the effectiveness of toilet bowl cleaning even when water usage standards are becoming more restrictive, especially with the introduction of pressurized rims. The conventional rim design (with a hole in the bottom for guiding flush water to clean the toilet area) remains problematic with respect to the lower surface, which is more difficult to clean and remain sterile. In recent years, toilets without rims introduced have provided an alternative to avoiding problems with rim cleanliness, but currently offer eddy current features, or longitudinal and horizontal flow. Relying on the action of pushing all the flush water along the guide, while balancing well along the guide passageway and in front of the toilet to achieve a sufficient flushing action. Furthermore, the conventional prior art toilet technology that does not have a rim portion for the purpose of washing and washing has the disadvantage that the water spot is smaller and the toilet is easily soiled.

  The art achieves the advantages of more traditional gravity toilets that use the rim washing ability to help clean the toilet surface while achieving excellent water washing ability, but these characteristics require a traditional rim. There is a need for a toilet that can still be brought in. More preferably, such toilets can also provide adequate siphoning in modern, water-saving toilets.

  In the present specification, a toilet is described which is also a siphon-type gravity toilet and does not have its own rim.

  The toilet without the rim described herein relates to the benefits achieved in the efficiency of flushing from the use of a spout-type toilet flush system and the cleanliness of the toilet and the design configuration without the rim. Designed to be able to incorporate the benefits of an enlarged internal toilet bowl or target area. The toilet can provide powerful flushing and cleaning capability without using the rim channel wash function and without pressurizing the rim water as in the conventional prior art spout type toilet bowl .

  The toilet allows a clean toilet after flushing and is free of today's 6.0 liters / 1 flush (1.6%) without the dirt and bacterial buildup that can occur in conventional toilets with protruding rim channels. Gallons / flush toilets) and, preferably, good flushing capabilities consistent with toilets utilizing 4.8 liters / flush (1.28 gallons / flush). The balance in achieving superior toilet cleanliness of a squirting toilet requires particularly rim channel support with current water standards. Direct-feed squirt toilets are known for their ability to remove large amounts of waste, but government standards for the use of flush water are becoming stricter and require design improvements to aid their cleaning function and performance It is said. Overall, the design support needed to meet such criteria is the traditional design of the rim channel (the rim channel pressurization and the unique design within the rim channel to change the water flow pattern. Resulting from unique design features that focus on the washing openings, etc. Government agencies continuously demand that urban water users reduce the amount of water they use. The main focus is on reducing the water demand required by rinsing. The amount of water used in the toilet for each flush is 7 gallons / flush (before the 1950s), 5.5 gallons / flush (until the late 1960s), 3.5 gallons / flush by government agencies It gradually decreases until (1980s). The 1995 National Energy Policy Act now mandates that toilets sold in the United States can use as much as 1.6 gallons per 1 wash (6 liters per 1 wash). A legislation recently passed in California requiring the use of water to be further reduced to 1.28 gallons per wash.

  Numerous prior art 1.6 gallon / 1 flush toilets lose the ability to consistently siphon when driven to these low levels of water consumption, and also have the ability to wash the toilet surface effectively. lose. While designs have been introduced to improve performance with low water usage, these improvements generally focus on traditional rim channel designs and / or trapway designs. Reinforcement and use of conventional rim channels has become a more important focus for maintaining and enhancing performance in siphon-type squirt toilets. Therefore, such a design has not been able to take advantage of the cleaner, rimless design as provided herein.

  Referring now to FIG. 1, a siphon gravity toilet without a rim is shown according to one embodiment. A toilet bowl generally indicated at 10 is shown with a tank 14 and a toilet bowl assembly 12. The unique features described herein will be described with reference to toilet bowl assembly 12, and it should be understood based on this disclosure that a tank, such as tank 14, is optional in the overall toilet design. . Accordingly, a toilet having separately attached toilet tanks as shown is within the scope of the present invention as being an integral (single) toilet design. The toilet can also be a wall mounted flush system engaged with a plumbing system (not shown) to form a toilet according to the present invention, in which case the water has a flush valve mounted on the top. Enter through or through a rear-facing entrance. Thus, any common type of toilet can be used in the present invention if it has a toilet bowl assembly as described herein. Whether it is from a tank as shown or from some other mechanism, its nature and the mechanism through which fluid is directed into the toilet toilet assembly inlet to flush the toilet can vary.

  As described in more detail below, a preferred embodiment of a toilet without a rim having a toilet bowl assembly according to the present invention does not exceed about 6.0 liters (1.6 gallons) per flush, Bacteria and conventional protrusions, even in toilets, which preferably do not exceed 4.8 liters (1.28 gallons) per wash, and do not exceed 3.8 liters (1.0 gallon) per wash While eliminating the problem of difficult manual cleaning around the rim, it is possible to provide a large amount of excrement removal and toilet flushing that is very good at the amount of flushing water. In addition, the preferred embodiment described below is higher in mass removal and can achieve a more consistent level of performance because the profile of the port that regulates flow to the toilet bowl is conventional. This is because it can be greatly simplified as compared with a toilet structure of a conventional toilet bowl-rim portion-trapway. The ability to achieve these standards at a wash volume of about 6.0 liters or less does not mean that the toilet described herein does not work well at higher flush volumes, and in general, It should be understood by one of ordinary skill in the art based on this disclosure that it means achieving good rinsing capability with higher rinsing amounts.

  As shown in FIGS. 1 and 2, the toilet bowl assembly 12 includes a toilet bowl assembly body 16 that includes a toilet bowl assembly inlet 18 for receiving fluid from a fluid source 20. The fluid source may be any tank, tube, or other mechanism for delivering water to the toilet, including but not limited to the use of a tank, such as tank 14, a direct line, or a combination thereof. The toilet toilet assembly inlet 18 is in fluid communication with the fluid source 20 as described above. Thus, flush water is supplied by a tank 14, wall mounted, each supplied with a fluid, such as water from a city or other fluid source, such as by using various flush valves as known in the art. You can enter from the flasher. When a tank is present as shown, it is typically coupled over the toilet bowl assembly inlet 18 and over the rear portion 21 of the toilet bowl assembly body.

  Alternatively, the tank may be integrated with the toilet toilet assembly body 16 of the toilet 10 if it is located above the toilet toilet assembly inlet 18. Such a tank has a valve mechanism for replenishing the toilet with water used to initiate siphoning from the toilet toilet 24 through the toilet toilet assembly outlet 38 into the sewer, as well as after the flush cycle. F is included. Any such valve or flush mechanism F is suitable for use in the present invention. The present invention can also be used with a variety of single, double or multiple flush mechanisms. Thus, a water supply that can activate flush siphon action and direct water to the toilet bowl assembly inlet 18, including mechanisms that are known in the art or that will be developed in the future to provide dual and multiple flushing, etc. Any tank, flushing mechanism, etc. in communication with the source, such mechanism (s) can supply fluid to the toilet assembly, the inlet port of the rim channel and the inlet of the direct feed jet One of ordinary skill in the art based on this disclosure should understand that it can be used with the toilet bowl assembly herein if it is in fluid communication with the port.

  The toilet bowl assembly also includes a trapway 22, a toilet bowl 24, a spout 26, and a manifold 28. The toilet bowl assembly body 16 may be formed in a single mold or multiple mold sections if desired, using standard ceramic manufacturing techniques. The ceramic mold (s) are formed to provide an external aesthetic design or the like if the interior of the toilet bowl assembly body is configured to have features as described herein. Good. The outer surface of the toilet bowl assembly body may be formed with the inner surface 30 of the toilet bowl 24 to have a continuous glossy appearance that is aesthetically attractive and easy to clean.

  Toilet toilet 24 in assembly 12 is configured to have an upper toilet edge 32 and an internal toilet surface 30 that does not have a conventional hollow rim channel. The inner toilet surface defines an inner area A of the toilet bowl that receives flush water from a water source during flushing, and the inner area A also includes a toilet bowl assembly through which fluid from the fluid source flows into the toilet bowl assembly body. In fluid communication with the inlet. The shape of the inner surface 30 provided by the mold configuration when molding the ceramic structure can vary from a standard egg-shaped toilet shape to a more rounded toilet shape and various designs. The toilet bowl preferably has a lower portion 34 of the inner surface 30 that slopes smoothly towards the toilet toilet outlet 36 (entrance to the trapway), so that flushing water can be drained by siphon flushing. Toilet toilet assembly outlet, generally designed to allow flushing down trap way 22 downward toward toilet bowl outlet 36 and allowing waste to flow toward a sewer or septic waste removal area Exit 38.

  Manifold 28 receives fluid from toilet toilet assembly inlet 18 into manifold area 40 and fluid communication from the toilet toilet assembly inlet to spout 26 and into inlet port (s) 42 as described further below. Enable. The toilet bowl assembly has a longitudinal axis LL extending transversely to the plane PP defined by the upper peripheral edge of the toilet bowl, and in one embodiment the main manifold is preferably a toilet It extends in a direction generally transverse to the longitudinal axis of the toilet bowl. Accordingly, the manifold is preferably configured in a conventional manner to extend in a direction generally transverse to the toilet toilet longitudinal axis L-L, where the longitudinal axis L-L is the upper side of the toilet toilet. It extends in a direction transverse to the plane PP defined by the peripheral edge 32. The manifold can have other designs designed for various jet shapes, including a manifold extending in a generally longitudinal direction. Adjustments to optimize and regulate the flow to the toilet and spout ports, as described in co-pending US patent application Ser. No. 13 / 266,241, the relevant portions of which are incorporated herein by reference. It is also possible to use elements. Such adjustment elements are particularly preferred in embodiments where the flush volume is less than about 4.8 liters or the ratio of trapway volume to total flush volume is greater than about 40%.

The manifold has a first portion f ₁ of fluid for fluid entering the toilet toilet assembly inlet 18 to enter the spout 26 through the spout inlet 44 as shown by the flow arrows in FIG. It is configured to divide into a _second portion f ₂ for entering the interior area A of the toilet bowl 24 through one or more inlet ports 42 as indicated by the flow arrows. Preferably, the fluid flows from the toilet toilet assembly inlet 18 through the manifold 28 into the manifold region 40 where the fluid is pressurized and then flows into the spout 26 and into the inlet port (s) 42. Divided into flows. Flow f ₂ is from about 10% to about 50% of the total flow rate, more preferably it should be about 40% to about 20% of the total flow.

The spout 44 is preferably disposed in the lower portion 43 of the manifold 28. The spout 44 is in fluid communication with the toilet toilet assembly inlet 18. The spout 50 is in fluid communication with the toilet bowl outlet 36 and the toilet bowl assembly outlet 38. One or more ejection channel (s) 46 connect the ejection inlet 44 to the ejection outlet 50. The fluid enters the jet through the jet inlet 44 and flows through the jet channel (s) 46 having a hollow interior 48. The fluid flows out of the ejection channel (s) 46 at the ejection outlet 50 shown in the bottom 52 of the toilet bowl 24 in this embodiment. The illustrated at least one ejection channel (s) is designed to extend around the outside 56 of the toilet bowl 24 within the interior 54 of the toilet bowl assembly body 16. Ejection outlet 50, as shown in FIG. 5A with reference to flow f _5, the flow of fluid from the injection channel (s) 46, into the bottom 52 of the toilet bowl 24 or enters near, thereby, as shown in FIG. 5A with reference to flow f ₄ enters the toilet bowl inlet port 42, disposed as further along the toilet bowl inner surface ledge 58 formed in and merges with advanced fluid described below Is done. In the illustrated embodiment, the ejection channels are similar to those described in US Pat. No. 6,715,162 or US Patent Application Publication No. 2009 / 0241250Al, each incorporated herein by reference. Can take the form.

  The water in the squirt channel (s) 46 flows out of the spout outlet port 50 or sump in the trapway 22 and directs the strong and pressurized water stream to the toilet toilet outlet 36 which is also the trapway opening. wear. This strong, pressurized water stream can quickly begin siphoning within the trapway 22 to empty the toilet and drain its contents into a sewer pipe in communication with the toilet toilet assembly outlet 38. .

  FIG. 5 shows, in a partially exploded perspective view, a spout passage entering a trapway separated from a toilet bowl, according to the embodiment shown in FIGS. The water channel inside the squirt toilet, which is an example of a direct feed squirt type, first enters the stool assembly inlet 18 and then through the manifold 28 into the squirt inlet 44 and through two squirt channels 46 as shown. Including a channel, in which the jet flow is split around the outside of the toilet bowl after the jet inlet 44 and splits into two channels 46 which can merge with each other at the jet outlet and then trapped past the toilet toilet outlet 36 Entering the way 22, where these portions are shown partially disconnected and the toilet toilet bowl omitted to show the exit path.

  The toilet toilet entry port (s) 46 can exist as one port that faces one direction or two such ports that face away from each other. In addition, a plurality of such ports may be formed, but are preferably arranged to flush in the opposite direction along the shelf 58. The inlet port (s) are preferably located in the upper rear portion 60 of the toilet bowl 24. A surface 62 that covers the foremost end 64 of the manifold 28 that separates the manifold area 40 from the interior area A of the toilet bowl 24 can help function to pressurize fluid flowing through the inlet port (s) 42. As best shown in FIG. 4, the surface 62 can be formed in a recessed surface 68 that faces toward one side of the toilet bowl 24, with the shelf 58 outside the toilet bowl entry port (s) 42. If two such ports 42 are used so as to form a recessed portion 66 where it can begin to extend toward, the flow is outward from the entry point from the upper rear portion 60 of the toilet bowl. It may be embedded in the interior surface 30 of the toilet bowl 24 so as to proceed in the opposite direction toward the front face 70 of the toilet bowl.

  With respect to the embodiment of FIG. 1, the toilet bowl port (s) 42 may be configured and sized to regulate flow. Preferably, the inlet port (s) 42 are formed in a rounded (substantially circular) shape, but may be of various shapes, i.e. curved slits, oval holes, elliptical holes, etc. . The port (s) should have a diameter (or longest cross-sectional dimension) of about 5 mm to about 25 mm, preferably about 10 mm to about 20 mm for optimal flow pressure. These may be tailored for different effects in different toilet shapes.

As pointed out above, the toilet toilet entry port (s) 42 is located in the upper rear portion 60 of the toilet toilet 24. The inlet port (s) 42 are each configured to receive fluid from the manifold 28 into the interior region A of the toilet bowl 24 so that at least a portion of the fluid directed as flow f ₂ is shown in FIG. 5A. will proceed along the ledge 58 of the toilet bowl so that the flow f ₄ shown. The shelf 58 is formed in its internal surface 30 before the flow proceeds into the lower part or bottom 52 of the toilet bowl. In doing so, if one port is provided, a more concentrated flow can be directed to travel in a clockwise or counterclockwise direction along the shelf. When two opposing ports 42 (of multiple opposing ports) are used, the flow can travel outwardly from the surface 68 in both clockwise and counterclockwise directions, at which time either flow Also flows towards the front of the toilet bowl.

  The inner surface 30 in the upper peripheral portion 71 of the toilet bowl is formed with a ledge 58 along at least a portion 73 of the upper peripheral portion of the inner surface 30 below the upper peripheral edge 32 of the toilet bowl. Can be configured as follows. The shelf 58 is preferably sufficiently below the upper peripheral edge 32 to prevent the flushing fluid from splashing upwards, except that the amount of fluid exiting the toilet toilet inlet port (s) 42 is large. Positioned under the outflow of fluid from the port in the recessed surface 68 to capture the portion and direct this flow along the shelf. The shelf is preferably positioned about 10 mm to about 100 mm below the upper peripheral edge of the toilet bowl, more preferably about 20 mm to about 50 mm, although the design is also desired from the invention described herein. It can vary depending on the washing effect. The shelf 50 is also preferably located about 0 mm to about 20 mm below the location of the lowest toilet toilet entry port (s) 42.

  The ledge 58 can take a variety of configurations and can include longitudinally extending flow grooves or features that help maintain or direct flow along the ledge to a desired point. In addition, a slightly raised and / or slanted transversely extending feature that forces some flush water to drop from the shelf at various points, or alternatively, along the passageway. Can also be used. Such optional features may be designed for various flow patterns, but the shelf may also simply be a generally flat upper surface as shown. The upper surface 72 of the ledge is also in a downward direction with respect to the transverse width in the manner described in WO 2009/030904 Al, the relevant portions of which are incorporated herein by reference with respect to the port and ledge shape. You may incline along the path. Preferably, the shelf is inclined at about 1 ° to about 3 ° toward the center of the toilet bowl to prevent accumulation of stagnant water primarily after washing. The ledge may also be positioned slightly inclined along its longitudinal flow path as it proceeds from the rear portion 74 of the ledge 58 to the front portion 76 of the ledge, if desired.

The shelf 58 has a width w (measured transversely on the shelf). The width of the upper surface 72 of the ledge 58 may be constant or, as shown, may be greatest toward the rear portion 74 of the ledge 58 as compared to the front portion 76 of the ledge. The shelf 58 also has a width w that gradually decreases from the maximum width w ₁ toward the rear portion 74 of the shelf 58, as shown in FIG. 3, and an intermediate width such as a width W ₂ along the shelf. It may be configured to pass through and terminate with a small width w ₃ near the front portion 76 of the shelf 58. In one embodiment herein, the shelf 58 does not extend all around the upper peripheral portion 71 of the interior surface 30 of the toilet bowl 24. The shelf 58 may also be formed so as to extend across the entire upper peripheral portion of the interior surface of the toilet bowl. However, as shown, a ledge 58 having a progressively decreasing width extends around the upper peripheral portion of the toilet toilet interior surface to a region where the flow meets at the toilet bowl front 70, where the ledge 58 Has a width w of only about 0 mm to about 10 mm, and most of the confluence from both directions falls downward toward the bottom 52 of the toilet bowl 24, thereby entering the toilet bowl from the spout 50. It is preferably small enough to allow it to merge with the flow from the jet stream.

Optionally, in an alternative embodiment as shown in FIG. 9, the toilet bowl assembly 212, where the same elements have the same reference numbers as the embodiment of FIG. 1, is in the upper peripheral area 271 just below the upper peripheral edge 232. It has an upper hollow channel 299 formed. Additional fluid from the manifold under pressure can also enter the inlet 295 to the hollow channel 299 and travel until it reaches the hollow channel outlet 297. Additional such outlets 297 may be formed along this passageway as shown in FIG. 9, in which case two hollows at 9 o'clock and 3 o'clock positions, respectively, relative to the illustrated figure. There is a channel outlet 297. As the water exits the outlet, this continues further on the second shelf 259, which is formed in the upper peripheral region 271 just below the hollow channel 299 and has the outlet (s) 297. Preferably, as shown, the second shelf 259 is disposed above the shelf 258 that decreases in width as it approaches the front 270 of the toilet toilet 224 to receive flow from the toilet toilet entry port 242. Accordingly, the fluid flowing along the shelf with the flow f ₄ as noted above merges with the flow f ₆ shown in FIG. 9, where the two flows approach the front 270 of the toilet bowl 224. Then, it flows downward into the toilet bowl. Such a hollow channel can be formed to flow through a toilet structure that does not have an existing rim, and without the protrusions associated with conventional prior art rim channels. If desired, a further such outlet, such as outlet 297, forms a hollow channel and places the outlet opening along its length and / or the upper peripheral edge of the toilet bowl 224 in the assembly 212 If desired, it can be placed in fluid communication with the manifold with multiple shelves in the upper peripheral region 271 below 232.

  Referring to the embodiment of FIG. 1, an optional opening 78 may be provided in the toilet 24 herein to provide further cleaning specifically focused on the rear region 60, in which case This opening is located in the surface 62 around the center of the toilet toilet, preferably below it. If two inlet ports 42 are used, the opening 78 is preferably present between the two inlet ports 42. The opening 78 when formed in the surface 62 receives additional pressurized water from the manifold. However, as shown, the opening disposed below the surface 62 can accept a pressurized flow from the manifold 28 or the ejection channel 46 that is already already proceeding with a generally downward flow. it can. Additional fluid entering the opening 78 from the manifold or ejection channel must be directed to enter the toilet bowl in a generally downward direction in order to clean the rear region 60 of the interior surface 30 of the toilet bowl 24. This can be accomplished by including a distributor 79 disposed in or on the opening 78. The dispenser 79 can be formed from a variety of suitable materials including, but not limited to, polymers, polymer composites, or metal materials, and preferably provides fluid to wash the area between the toilet inlet ports 42. Positioned on the surface 62 or opening 78 to direct downward and outward.

  The distributor 79 is preferably formed so that it can be removably or permanently attached to the toilet bowl. Alternatively, the distributor 79 can be formed as an integral part of a toilet bowl, for example by placing the longitudinal wall of the melted porcelain about 2 mm to about 20 mm in front of the opening 78, thereby During the flush cycle, fluid exiting the opening collides with the wall and is directed downward and outward to wash the rear portion of the toilet bowl. Such a structure can be achieved in the melted porcelain by attaching the distributor features to the toilet bowl as they are all out of the mold (ie, prior to high temperature combustion). This distributor feature as described above is further in the direction in which the flow along the shelves is opposite, and the strong jetting action ensures that the small areas where the flow is difficult to reach along the surface are properly cleaned. To be sure.

  In one embodiment, the dispenser may simply be a cover 80 that bends the flow down into the toilet bowl. Alternatively, as shown in FIGS. 10-14, the distributor may be an assembly of components that includes a cover 80, in addition to being part of the distributor as an assembly, the cover 80 It may also be provided to improve the aesthetics of the vessel features. Whether acting as a distributor itself or as a cover for a distributor assembly, the cover can have a variety of designs, including but not limited to composite materials, color matching materials, ceramics, stainless steel, etc. May be formed from a variety of materials. The cover must extend toward the interior area of the toilet bowl 24 sufficiently outward to provide a flow entry and direct the flow downward along the interior surface 30 of the toilet bowl 24. Alternatively, the distributor and the decorative cover can be unitary.

  In the assembly as shown in FIG. 10, the distributor assembly 79 includes a cover 80, an optional distributor guide 77, a distributor lock 81, and a distributor fastener 75. The fasteners can be any of a variety of fasteners, including press fits, snap fits, interlocking parts, or screws 75 as shown herein. The distributor is shown in an exploded view at the intended location in FIG. 10 and an expanded view in FIG. As shown in FIG. 11, the cover is configured to fit over a preferred distributor guide. The guide is again formed for this purpose with an upper part 77e for deflecting the flow downwards and a front surface part 77a, the front surface part 77a for mating with the cover. And the toilet when installed to allow flow to flow downward and slightly outward along the distributor guide, thereby allowing it to spread and contact the interior surface 30 of the toilet bowl 24 Slowly incline outward from the back of the toilet. The distributor guide 77 also incorporates a transversely extending through hole 77c for receiving the distributor screw 75, as best shown in FIG. When using the preferred distributor assembly 79, the cover 80 is optional but can be used to hide the screw head for aesthetic purposes. Further, the cover 80 can be removed to clean the toilet near the hole 78 and the screw 75 can also be removed by removing the distributor lock.

  The distributor lock operates like a nut and can be configured in the form of a conventional nut or washer, or along the perimeter 81b as shown to facilitate installation and removal, gripping feature 81a. It is possible to have a surrounding shape designed in consideration of The distributor lock also has an opening 81c that passes transversely as shown to receive the distributor screw 75.

  As shown in FIGS. 12 and 13 from the rear view, the distributor guide 77 may be made to have a feature 77d for directing the flow. As shown, the area through which the screw 75 passes through the distributor can be extended backwards with optional threads on the inside of the hole 77c if desired. The rearwardly extending portion 77f directs flow downward along and behind the rear surface 77b, thereby cleaning the interior surface 30 of the toilet bowl to clean the region 60 and below that region on the interior surface 30. Can be used to provide a mounting base for one or more features, such as feature 77d, for spreading downwards toward As shown, feature 77d is simply a divider, but grooves, channels, multiple dividers, etc. may be provided on the rear surface 77b of distributor guide 77 without departing from the spirit and scope of the present invention. .

When assembled and installed on the toilet as shown in FIG. 14 from the rear view, the distributor lock 81 tightens the screw 75 and fits onto it, which screw 75 causes the distributor guide 77 and the distributor lock 81 to engage. The lock is tightened against the inner manifold surface 29 behind the surface 62 that covers the manifold at the top of the opening 78, and the rear surface 77 b of the distributor guide is at the top of the opening 78 of the toilet bowl 24. It is clamped against the inner surface 30. Thus, the distributor guide is fixed and the cover 80 can be placed over the distributor guide. Flow may thus proceeds in a downward direction into the toilet bowl along the flow f ₃ shown in FIG. 14.

  Alternatively, the cover 80 can be used over the hole 78 without having a distributor guide, screw, and lock, and can function both aesthetically and functionally as a distributor. In the preferred embodiment herein, the cover 80 is part of a distributor 79 that is an assembly as noted above.

In further embodiments herein, the toilet may have an alternative toilet toilet assembly 112 as shown in FIG. Such an alternative assembly may be used in the toilet 100 which is identical to that described above with respect to the toilet 10, except for the toilet bowl assembly 112, where the same numbers are used to refer to the same parts throughout. . The toilet bowl assembly 112 is further the same except for the spout design. In the toilet bowl assembly 112, the spout 144 is preferably again located in the lower portion 143 of the toilet bowl assembly manifold 128. The spout inlet 144 is in fluid communication with the toilet bowl assembly inlet 118. The spout outlet 150 is in fluid communication with the toilet bowl outlet 136 and the toilet bowl assembly outlet 138. One or more ejection channel (s) 146 connect the ejection inlet 144 to the ejection outlet 150. The fluid enters the jet through the jet inlet 144 and flows through the jet channel (s) 146 having a hollow interior 148. Within the ejection channel (s), the fluid flows through the ejection channel (s) 146 along the upper portion of the toilet as shown and exits at the ejection outlet 150 in the illustrated embodiment, but the fluid until flow along the flow f ₇ as shown in FIG 6 to the front 170 of the proximal toilet bowl 124 of the upper peripheral portion 171 of the toilet bowl 124 does not proceed in a downward direction toward the ejection outlet 150.

The at least one spout channel (s) 146 shown in FIG. 6 is designed to extend within the interior 154 of the toilet bowl assembly body 116 to travel around the outside 156 of the toilet bowl 124, but with an inwardly extending shelf.
