Description

Anti-splash urinal

The present invention relates generally to urinals, and more particularly to wall and/or floor mounted urinals designed to minimize splashback, odor and water consumption. The invention also relates to a urinal with a custom cover having a shape and color/pattern to match the room.

Men's restrooms typically include urinals fixed to the wall and/or floor. These urinals provide convenient urination passage for male customers. Additionally, these bowls save space and reduce the amount of water used by an otherwise used toilet bowl.

A common problem with conventional urinals is the well-known phenomenon of backsplash. Kickback occurs when urine droplets are deflected backwards toward the user due to the force of the user's urine stream hitting the bowl surface. See Figure 5a. This can cause unpleasant markings on the user's clothing as well as a health hazard. The force of the rinse water can also cause backsplash to occur.

Another common problem with conventional urinals is that they often emit a foul odor. When the urine stream hits the bowl surface, some of the urine droplets will evaporate. Minimizing backsplash will greatly reduce the amount of malodors produced by the toilet and will lessen the health hazard.

Furthermore, conventional urinals typically consume 1 gallon or more of water per flush. Although low-volume and water-free urinals have been proposed and met with limited success, they still suffer from backsplash and are often malodorous.

Several inventions are aimed at correcting these problems. Innovations that address the backsplash problem include cone bowls, v-shaped bowls with offset apex, and bowls with splash screens. See, eg, US Patent No. 5,027,448; US Patent No. 5,287,563; US Patent No. 5,806,107; US Patent No. 6,470,504. The disadvantage of these designs is that when the urine flow is deflected in different directions, the evaporated urine volume still has odor and hygiene problems.

Still other inventions are directly directed to the problem of dealing with malodors. These options include urinals with ventilation systems and urinals with gutters. See, eg, US Patent No. 704,471; US Patent No. 2,646,574; US Patent No. 5,305,473; US Patent No. 6,088,845.

The present invention fulfills the need for a urinal with features that reduce backsplash, evaporation, and other phenomena resulting from hygiene and odor problems. The invention provides an anti-splash urinal, which includes a bowl for receiving urine from a user, and the bowl has a curved surface to reduce the impact angle between the urine and the surface and to urine flows down and away from the user; an aperture through which the user stores urine in the barrel, the aperture being off-center relative to the barrel; and a drain having an orientation offset from the aperture .

The urinal can also include a custom cover with a shape and color/pattern to match the room. In a preferred embodiment of the invention, the urinal is equipped with a low flow flushing system, which is used to reduce the volume of evaporated water and urine while simultaneously reducing the amount of water used per flush. In a preferred embodiment of the invention, the low flow flushing system has an armature made of plumbing tubing which is bent to a shape which partially follows the shape of the cylinder. Nozzles disperse water or other liquid (in the form of a mist, spray, stream or other fluid) onto the surface of the barrel. The armature can be fabricated integrally to the bowl or bowl or separately. The armature can also be adapted to hold conventional bowls.

In a specific embodiment, the bowl further includes an air filter connected to the exhaust system. The air in and outside the bowl enters the exhaust system through the air filter. The exhaust system is connected to a fan that can be manually activated via a motion sensor, or can run continuously. Preferably, the air filter is a water stripping filter designed to remove moisture from the air as it enters the exhaust system.

The present invention provides a wall- or floor-mounted toilet designed to minimize or eliminate backsplash, while maximizing capacity and removing substantially all liquid, vapor and gas entering and/or generated within the bowl. Also, unlike conventional urinals, the urinal of the present invention can be customized in terms of external aesthetics, including but not limited to style, color, texture, and pattern.

Referring to Figures 1-4, the anti-splash toilet 10 according to the present invention includes a barrel 12 having an opening 18 for receiving urine. The barrel 12 includes an inner surface 24 that has a curved design to reduce the angle of impact of urine flow from the user (i.e., from vertical) so that the urine is directed inwardly and downwardly as it flows toward the inner surface 24. away from the opening 18 . The reduced angle of impact reduces backsplash and evaporation. In a preferred embodiment of the invention, the inner surface 24 has a generally epicycloidal or cardioid or cardioid profile. The opening 18 is preferably located on the side facing the barrel 12 so that the inner surface 24 of the barrel 12 (including the drain 22 at the bottom of the barrel 12 ) is not aligned with the opening 18 . With this configuration, the flow of urine will be straight down and away from the aperture 18 preventing backsplash and evaporation. See Figure 5B. In addition, the shape of the barrel 12, as defined by the shape of the inner surface 24, and the limited passage through the holes 18 on the inner surface 24 provide the ability to trap unpleasant odors and unsanitary vapors and gases inside the barrel 12, That is, functionally similar to vessel hoods typically found in chemistry laboratories and the like.

The bowl 10 may be formed from any type of material that is impermeable to fluids (eg, liquids and gases), including, but not limited to, ceramic, plastic, glass, and/or metal. The outer surface of the barrel 12 may be of any shape, while the inner surface should have a curved shape as described above and may not be constrained by the shape of the outer surface. In a preferred embodiment of the present invention, the bowl 10 has an outer, non-functional cover 20 which can have various shapes and colors/patterns to suit the room.

Figure 3 shows a cross-sectional view of the bowl of Figure 1 along line 3-3. As can be seen from Figures 3 and 5B, the shape of the barrel inner surface 24 aligns with the flow of urine and prevents backsplash and reduces evaporation and aerosolization associated with urination and flushing. When urine contacts inner surface 24 , the urine is diverted or directed away from aperture 18 and toward drain 22 . Additionally, the shape allows urine to better conform to the inner surface 24 and return along the surface toward the drain 22 rather than away from the inner surface 24 toward the user. This reduction in misalignment and directing the urine away from the aperture 18 provides prevention of backsplash. Additionally, the shape of the inner surface 24 provides a more laminar rather than turbulent flow, further reducing evaporation and aerosolization associated with urination and flushing. The shape of the inner surface 24 in horizontal and vertical cross-sections can be various curvilinear shapes, but is preferably heart-shaped. Additionally, although locating the drain 22 offset from the aperture 18 is particularly beneficial, the drain may be located anywhere within the bowl 12 so long as the drain 22 functions to drain the bowl 10 of liquid. Furthermore, although the receiving aperture 18 is described as being generally rectilinear in shape with curved corners, the shape and size of the aperture is not limited to that shown and it may be any shape effective to allow access to the barrel 12. Any size and shape to store urine while minimizing splashback, malodour, and unsanitary vapors and gases.

FIG. 2 depicts an exploded perspective view of a backsplash bowl 10 according to another embodiment of the present invention. The urinal 10 includes a cylinder body 12 , a cap body 14 , a filter 16 and a fixing frame 26 . The bowl 10 also has an aperture 28 configured to receive and retain the filter 16 . The bowl 10 may also include apertures 30 through which air may freely pass. Holes 28 and 30 are also used to accommodate tubing for flushing purposes and to allow clean water to enter barrel 12 during flushing. The mount 26 provides a substantially flat surface, wherein the mount 26 allows the bowl 10 to be secured to be substantially flush with the wall. Although the mount 26 can be used to secure the bowl to the wall, the mount 26 can also be extended to secure the bowl 10 to the floor. The mount 26 also provides access to the bottom of the bowl 10 . Filter 16 is used to filter moisture that may be evacuated from the air through holes 28 and 30 . As an example, air may rise through holes 28 and flow through holes 30 upon evacuation. Cap 14 prevents air from escaping from bowl 10 and also directs airflow from aperture 28 to aperture 30 . As the air flows through the holes 28 and the filter 16 , the filter 16 extracts moisture from the air and returns it to the inner surface 24 of the barrel 12 .

Referring again to FIG. 3 , the cover 20 may also have a void 32 that provides additional space that may be used to accommodate air flow and vent to the barrel 12 . Alternatively, cover 20 may be a solid piece, which may serve primarily aesthetic purposes. In addition, the cover 20 is not limited to use strictly with the anti-splash bowl 10 according to the present invention, but may be adapted for use with conventional bowls fixed to walls and/or floors. In this case, the cover 20 may also provide splashback reduction by partially covering the hole of a conventional bowl to limit the chance of backsplash. During manufacture, the cover 20 may be formed from colored, painted and/or incorporated fabric, wallpaper and/or any other material so that the cover matches the color and decor of the restroom in which the cover is used. Harmonize or contrast. For example, fabric or wallpaper that fits the interior of a toilet can be laminated to the cover and protected by a varnish coat.

Referring specifically to Figure 4, in a preferred embodiment of the present invention, an exhaust system is attached to the bowl 10 so that the bowl can be ventilated through the bottom of the bowl and through ducts located in the wall to which the bowl 10 is secured. exhaust. In this embodiment, air may be introduced from an electric fan located on the attic, ceiling and/or walls of the washroom or outside the building (eg on the roof). A fan may also be located within the bowl 10, where the fan draws air in from the bowl 12 and exhausts air out of the toilet. The electric fan can be a conventional exhaust fan currently used in toilets. When the fan is running, air is introduced into the barrel 12 via the receiving hole 18 . The air flows through the inner surface 24 of the barrel 12 , the filter 16 , the holes 28 and the holes 30 as the airflow 44 and is expelled through the duct 42 in the wall 40 through the opening in the mount 26 . This makes it possible to evacuate air that may contain foul odors, unsanitary vapors, and gases compatible with urine. Embodiments of the present invention can evacuate air at volumetric flow rates such as, but not limited to, 50 cubic feet per minute. This emptying substantially eliminates any odors that may be released from the bowl 10 . It should be understood that the emptying rate may be any volumetric flow rate sufficient to remove malodors, vapors and gases within the bowl 12 and from the air surrounding the bowl. Alternatively, air may be drawn in convectively from the barrel.

Filter 16 may be used in embodiments of the invention utilizing an exhaust system. The filter 16 serves to retain moisture that may be present in the air drawn in through the airflow 44 and to return this moisture to the cartridge 12 . For example, filter 16 may be formed using a layer of rigid material containing off-center openings. The offset of the openings creates a non-linear motion for the gas passing through the filter 16, thereby increasing the filtering capacity of the filter 16. Moisture is filtered from the gas and returned to the barrel 12 . This helps to reduce the amount of moisture that might otherwise enter the plumbing and further eliminates condensation that may form on components of the bowl 10 located at the rear that are only accessible through the holes 30 when the bowl 10 is secured. This includes coagulation of urine, which would otherwise create hygiene problems on the back of the bowl 10 . The filter 16 serves to prevent this sanitation problem and substantially prevents the formation of condensation on the back of the bowl 10 .

The exhaust fan may run continuously or intermittently, for example, activated by a motion sensor that senses when a user approaches the bowl. The exhaust fan can also be energized to run while the bowl is flushing.

Another feature and advantage of the present invention arising from the unique cartridge design is the ability to operate with extremely low water consumption (ie, low flow flushing systems). This low-flow flushing system utilizes clean water in both liquid and mist form. The flushing system may be attached to the bowl through openings in the mount 26, wherein holes 28 and 30 are utilized to facilitate the flushing system and/or despite the drain 22, and wherein a portion of the drain 22 will be dedicated to allowing water to flow into the bowl 12 For flushing purposes. The flushing system will use mist and liquid water to clean the interior surface 24 of the bowl 12 and expel the water and urine from the bowl through the drain. The low flow flushing system also serves for less evaporation of urine carried within the cartridge 12 . Evaporation is prevalent during regular toilet flushes, and the amount of urine contained therein will also evaporate. Additionally flushing of conventional urinals can also result in the water/urine mixture being splashed back to the user and/or to the surrounding area including the floor. These limitations of typical bowl flushing systems are avoided by the low flow flushing system of embodiments of the present invention.

In a preferred embodiment of the invention, a mist flushing system is utilized consisting of toilet tubing (3/8" OD, 1/4" ID copper tubing in one specific case) that has been Curved into a crescent shape having a height of about 7" from the drain opening to the top of the mist hole and having a radius of curvature that allows the crescent shape to follow the inside wall of the barrel.

Atomizing armatures were tested in a variety of configurations, including vertical crescents 800 (see FIGS. 6A and 6B ) and annular holes 900 (see FIG. 7 ) ranging in diameter from 3 to 12 inches. The tested armature consisted of 1 to 12 atomizing heads.

The misting system can be integrated into the bowl body or completely separate from the bowl. The atomizer, which is separate from the bowl, may protrude from within the area of the drain, or from the top, side, or adjacent to the bowl front opening. The misting system can also penetrate the inner barrel to release a mist from the inside of the barrel or towards the barrel. However, other locations may also be suitable including, but not limited to, the top hole, the front hole, or through the inner wall of the barrel at almost any point. Alternatively, the misting system may be integrally formed with the barrel wall itself and incorporated into the barrel through a manifold or other water supply peripheral. Direction, speed, flow rate and form of water (droplets, mist, liquid flow, spray, mist, steam, etc.) Or gas form is discharged to the cylinder. Other embodiments of the atomizing system include an atomizing channel that surrounds the front aperture and or top aperture and directs the mist to the barrel and away from exiting the front aperture.

Droplet size can vary with water pressure and modified/specialized atomizing nozzles. The smaller the size of the water droplet, the greater the surface area it covers for a given volume of water. Therefore, higher flushing pressures and specialized atomizing heads will result in less volumes of water being used.

Regardless of whether 1) the ventilation system is attached to the bowl and activated or 2) it is not attached to the bowl or activated, the misting system is on the inside shape of the barrel (i.e. producing mist) and the orientation of the mist nozzle results in No mist leaves the barrel.

During testing, a mist rinse for 37 minutes resulted in the consumption of 2 quarts of rinse water. The tested mist armature is crescent shaped and discharges mist simultaneously through 4 atomizing nozzles. A target rinse length of less than 3 minutes will consume less than one-tenth of the water consumed in the aforementioned assays. As a result, water consumption will be less than 1 pint per flush.

Various atomizing nozzles are commercially available and may be beneficially used in the present invention, including but not limited to: 1) Brass Misting Nozzles, Mist & Cool, L.L.C., Simi Valley, CA93065; "For pressures up to 250 PSI" ; MClO3C: 1/2to 1 Gallon Per Hour per mist head, 10-24 UNC thread; or 2) Raindrip, TornadoFogger/Mister; 7 Gallons Per Hour per mist head; #162005; all plastic nozzles.

Copper atomizing nozzles from Mist & Cool L.L.C. result in smaller mist droplets; thus reducing the amount of water required to thoroughly cover the interior of the barrel. Reducing the size of the mist droplets results in a greater total surface area of water and thus requires less total water volume to cover the same area of bowl surface. Thus, a higher water pressure or even a finer mist nozzle will result in a smaller amount of water being converted into a mist which will be sufficient to cover/coat/clean the same area of bowl surface.

The misting system can be used as a stand-alone tool for flushing a toilet or in combination with a liquid flushing system utilizing any other type of liquid, including steam, mist, spray, stream, atomized liquid, and the like.

Water pressure boosters, and air compressors used in conjunction with toilet plumbing systems can be used to further increase the water pressure to result in a finer mist (smaller water droplets), which are used in misting systems to further reduce urinal pressure. water consumption.

Another embodiment of the invention involves the use of a water stripper as an air filter. A water stripper according to the present invention filters and/or strips fluids, including but not limited to water, liquids, mist, steam, mist, moisture, from the air drawn from the bowl of the urinal and/or from the air surrounding the urinal wait.

Water strippers for bowls can be placed anywhere along the path of the air drawn from the inside of the bowl. In one embodiment, the air stripper is mounted to fit into the entire top vent of the bowl (see Figures 8A and 8B) so that when air is sucked out of the bowl by the ventilation system and into a duct within the wall of the stationary bowl, or Into the tubing outside the bowl (see Figures 8C and 8D) through which no air can bypass it and all air must pass through it as it is drawn from the bowl or elsewhere in the restroom.

Without being bound by any theory, it is believed that the water stripper operates on the principle of conservation of momentum. Accordingly, liquids of any kind (mist, vapor, atomized liquid, mist, moisture, droplets, and liquid streams) that may be entrained in the gas stream passing through the water stripper due to their significantly greater mass than air And has a higher momentum than air itself. Because the air passing through the stripper is forced to change direction suddenly due to the shape of the path through the stripper, any kind of liquid entrained cannot change direction as quickly as the air; on the solid surface of the vessel and adheres away from the air flow that carried it there.

After the liquid hits the surface of the stripper, the air is thus dehumidified (with less liquid) and travels through the air ventilation system. As more and more liquid hits the stripper surface, the gas that hits the stripper surface condenses and collects on the stripper surface in increasing amounts (droplets). Liquid of any kind (including but not limited to steam, mist, droplets, liquid streams, aerosolized urine, etc.) is continuously produced on the stripper and continuously impinged and collected until: or 1) the droplets become too large so that gravity causes it to leave its attachment surface and return toward and into the cylinder; or 2) the droplets do not continue to grow, but slowly evaporate back into the air flow passing them, where the air becomes less humid and substantially Dry the surface of the stripper. When the mist system is in operation and most of the clean water intended to wash the bowl actually passes through dripping back into the bowl and down the drain, the humidity in the airflow can be substantially reduced.

The present invention may encompass any of a variety of toilet water strippers. As shown in Figure 9, the variety of water strippers may include, but is not limited to, parallel surface plates with parallel strips 1101, circular and other shaped extruded helix eccentric holes 1102, and fans that behave like stacked stacks Layer 1103 of the blade. A water stripper typically directs the air to change velocity (by increasing or decreasing the cross-sectional area of the path the air passes through) and/or it abruptly changes the direction of the airflow so that there is no straight path or even a zigzag path for the airflow to pass, so that the extracted The liquid is introduced to impact and adhere to the surface. Figure 9 depicts how a rigid material can be cut in 2-D so that it provides both a change in direction and a change in velocity of the liquid flow in the water stripper.

When in use, the mist flushing water evenly covers the entire inner surface of the cylinder. The internal shape of the bowl and the orientation of the mist nozzles, as well as the orientation and direction of the air being drawn into the bowl roof vents through the ventilation system can create an air vortex within the bowl which even promotes misting of the entire bowl bowl And the complete coverage of the mist inside the barrel.

The internal shape of the barrel also promotes swirling of the gas and liquid streams within it. This vortex effect has multiple purposes, including but not limited to: 1) reducing turbulence and increasing laminar flow of urine (or other liquid flow) entering the barrel from the front hole (reduction of this turbulence reduces splash back) and reducing vaporization , atomization and evaporation, otherwise it will cause odor; 2) Reduce the turbulence and increase the laminar flow of the flushing water through the cylinder wall; 3) The even distribution of the flushing system mist through the cylinder inner wall; 4) Along the front hole The air vortex is created so that the mist is prevented from exiting the bowl of the bowl; and 5) The vortex is also used to release the mist droplets against the sides of the bowl before they are absorbed by the mist stripper in the top hole of the bowl.

The internal shape of the barrel, the orientation of the mist nozzles, and the airflow being drawn into the front hole and eventually exiting the top hole of the barrel (via the water stripper) all work together to create a vortex that reduces odor, backsplash, and water consumption.

A vortex can be created around the front hole, which leads to at least two advantages: 1) it keeps the mist to be produced inside the barrel, along the inner wall of the barrel, and even against the path of the main airflow entering the barrel through the front hole, thereby , completely and uniformly coats the wall of the bowl all the way to the top hole, and 2) it keeps the mist calm and contained inside the barrel without any escape from the barrel through the front hole.

Even without any operable ventilation system attached to the bowl, the mist itself reduces, suppresses, isolates and removes odors from the air. Thus, despite the absence of an existing or working ventilation system, the misting system of the bowl will substantially reduce and/or eliminate odors within the bowl of the bowl that would otherwise escape into and contaminate the surrounding restrooms and fixtures.

The ventilation system also draws air into the bowl from outside the bowl and thus can further reduce restroom odors.

Various changes can be made without departing from the spirit and scope of the invention. For example, the non-functional cover 20 may be formed as a separate element sized and shaped to fit a conventional bowl. The cover may comprise a non-functional shell, cover or other rigid or flexible material, which may comprise a flexible, adhered backed panel or fabric for direct attachment to an existing bowl, or as shown in Figures 10A-10C and 11A -11C, the cover may be formed from rigid or formed sheet, or cast constructed. Thus, it is possible to update the appearance of an installed urinal, for example in a retrofit. Alternatively, the gas filter/water stripper can be incorporated into a conventional bathroom exhaust system.
