This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.

As used herein, the terms “hygienic apparatus”, “hygienic unit”, and “hygienic system” refer without limitation to any device that can dispose, process, treat, eliminate, divert, reduce, and/or pulverize liquid, gas, or solid waste including without limitation toilets, urinals and bidets.

The terms “flow completing structure” refer to, without limitation, any structure, tubing, tubular winding, inclined tubular and/or hollow liquid and/or solid carrying structure, spiral tubing, or the like which contains a flow of waste form the containment chamber to assist in completing emptying the containment chamber.

Furthermore, the terms “low flow” refer to without limitation to any system which reduces, minimizes, or the like the requirement for inlet liquid, e.g., fresh water, recycled water, or the like.

The terms “containment chamber” refers to without limitation any chamber, vessel, container, hollow structure, or the like which receives solid waste in a container interior, holds the solid waste while the waste is broken-up, and include a container outlet allowing the broken-up solid waste to escape.

Finally, the terms “at least one shaped portion” refers to without limitation a section of a containment chamber which collects liquids and/or solids for transport or movement to a drain tube of the hygienic apparatus.

Overview

In one salient aspect, the present invention discloses an apparatus and method of producing a hygienic system, inter alia, which reduces water usage compared with known toilets. In particular, the hygienic system disclosed includes a containment chamber having an input portion and an output portion. The containment chamber configured to move liquids and solids between an inlet port and an outlet port. The containment chamber, in one exemplary embodiment, is configured to fill to a prescribed volume level. At least one shaped portion of the containment chamber prevents backflow of odor associated with the liquids and solids.

A first nozzle is disposed in the containment chamber and configured to break-up the solids using a prescribed pressure level to propel the liquids and the solids from the first port through the second port of the containment chamber. A velocity-increasing structure is disposed between the outlet port of the containment chamber and the drain tube of the hygienic system. The velocity-increasing structure provides an effective increase in the velocity of the liquids and solids.

Consequently, the present invention may be used to move or transport liquids and/or solids for a multitude of applications, such as for example for sewage treatment plants, nuclear waste plants, chemical treatment plant and other like liquid and solid treatment applications.

Broadly, the present invention generally provides an apparatus and method for providing improvements in efficiency and water usage for many liquid and solid treatment applications. The system of the present invention may find beneficial use for disposal of liquids and any solids which may be broken up by a high pressure water spray, and any system including a containment chamber and a high pressure spay directed into the containment chamber for breaking up solids and pushing the broken-up solids from the containment chamber, is intended to come within the scope of the present invention.

In yet another exemplary application, the system may prove useful for transporting liquids and solid masses that are deposited in a storm drain or other undesired location. More specifically, the system may be part of a liquid and solid waste recovery system that collects liquids and solids and/or provides these liquids and solids in a more compressed form to reduce packaging required for hauling away.

Furthermore, the same system may prove useful in a hospital and/or nursing home setting whereby liquids or solids, e.g., blood, IV apparatus, urine, solid matter, and the like, are needed to be either distributed and/or collected from each hospital recovery room and either transported or packaged for disposed in a centralized area. Consequently, an operator using this system may have the ability to track movement of liquids and/or solids on an individual basis, collectively, or sort and process separately liquid and/or solids. In addition, the system is adaptable to utilize recycled water and/or liquids so as to conserve water usage either on an individual basis or collectively if more than one of these systems are installed in a multi-room unit, for example, an apartment building, a condo, a home, or the like.

In addition, the invention is described as an automatic flush toilet using a containment chamber having at least one shaped portion that provides a holding chamber to collect the liquids and solids. Furthermore, the principles and methods of this invention may further be applied just as readily to other technologies, products, and devices, such as non-automatic hygienic systems, blood centrifuge or distribution systems, chemical treatment facilities, and water and sewage recovery facilities for dams, lakes, rivers, streams, and the like.

Exemplary Extension Apparatus

Referring now to FIGS. 2A-18, features of a hygienic system according to the present invention are described in detail. It will be appreciated that while described primarily in the context of hygienic system for transport liquid and solid waste products, at least portions of the apparatus and methods described herein may be used in other applications. Some such applications include, e.g., health monitoring and/or warehouse transport systems that transport liquids or solids from one location to another location within a larger assembly line process.

FIG. 2A illustrates a front view of a hygienic apparatus 4 in accordance with an embodiment of the present invention with a toilet lid 5 and a toilet seat 8 in an up position and FIG. 2B illustrates a rear view of the hygienic apparatus 4 with the toilet lid 5 and the toilet seat 8 in a down position. The toilet lid 5 and the toilet seat 8 attach, e.g., using hinges 6, to a toilet base unit 14. The toilet lid 5 may be manufactured from a single layer material, a multilayer material, composite material, and/or combination of these materials. Example materials include plastic, polyurethane, wood, glass, and finished and/or painted to achieve a desired toilet esthetic or physical appearance. A toilet seat or ring 8 attaches, e.g., using hinges 7 to the toilet bowl 28, or some other feature of the hygienic apparatus 4. The toilet seat 8, in many instances, is produced or manufactured from similar materials as that of the toilet lid 5.

A right side cross-sectional view of the hygienic apparatus 4 taken along line 3-3 of FIG. 2A is shown in FIG. 3 with the toilet lid 5 and the toilet seat 8 in the up position and a left side cross-sectional view of the hygienic apparatus 4 taken along line 4-4 of FIG. 2B is shown in FIG. 4 with the toilet lid 5 and the toilet seat 8 in the down position. Spray jets 26a-26n (collectively spray jets 26) reside along a toilet rim 9 to pre-dampen and to further clean or clear a toilet bowl interior 28a.

In this example, the spray jets 26a-26n are low pressure nozzles which preferably produce a mist of liquid, such as water, covering the inner surface 28a of the toilet bowl 28. A very fine layer that results from the mist of liquid, which takes advantage of molecular properties of water, prevents solids and liquids that are transported along the inner surface 28a from sticking and/or attaching. In an alternative embodiment, the liquid, which in this example is water, may be replaced by a cleaning fluid, soapy water, enzyme rich liquid, or the like for conditioning, lubricating and/or cleaning the toilet bowl 28. A pump 10 provides a flow of liquid to the spray jets 26a-26n through line 22a. In contrast to conventional toilet systems, the pressure for spray jets 26h-26k, in one embodiment, may be of a medium pressure, e.g., 50 to 400 p.s.i., as compared to nozzle 24 at a high pressure, e.g., 500 to 2500 p.s.i.; thus, a more controllable and less back spraying flush may be realized.

Still referring to FIGS. 3 and 4, a fine mist of fluid droplets trickle from spray jets 26h-26n onto an inner surface 28a of the toilet bowl 28. In this exemplary example, when an individual (not shown) opens the toilet seat 8 for use (as shown in FIG. 2A), the fine mist of fluid droplets 25 trickle from spray jets 26h-26n. The fine mist of fluid droplets 25 adheres to the inner surface 28a of the toilet bowl 28 to pre-wet the inner surface 28a. The droplets 25 lubricate and reduce or prevent solids or liquids sticking to the toilet bowl 28. In other words, the droplets 25 reduce or prevent solids or liquids from staining the toilet bowl inner surface 28a. Fluids, including fluid droplets, solids and liquids, collect in a containment chamber 20. Fluids continue to flow into the chamber 20 until the chamber 20 is filled to, in one exemplary embodiment, to a level wherein the containment chamber 20 contains approximately of one-sixteenth to one-eighth of a gallon. The containment chamber 20 thus serves as a reservoir which provides a collection area for containing the fluids entering the toilet bowl 28. The containment chamber 20 includes a chamber floor 20a, a chamber ceiling 20b, a chamber inlet 21a, and a chamber outlet 21b, and a container interior bounded by the container floor 20a, the chamber ceiling 20b, the chamber inlet 21a, and the chamber outlet 21b. The chamber floor 20a is preferably straight and the chamber ceiling 20b is preferably concave upward. The toilet base 14 provides housing for the containment chamber 20. As compared to conventional standard toilets, no polymer (e.g. rubber) or other type of seals (e.g., wax) is required because fluid is maintained in the containment chamber 20. Thus, this invention is not subject to failures associated with faulty seals.

Continuing with FIGS. 3 and 4. A high pressure nozzle 24 is pointed into the containment chamber 20 opposite the chamber outlet 21b. The high pressure nozzle is fed by the pump 10 with a high pressure flow of water, sufficient to break-up solid waste material in the containment chamber 20 and to push the broken-up material out of the containment chamber through the chamber outlet 21b. Preferably, when the toilet lid 5 and the toilet seat 8 are in a closed position following use, and the pump 10 is activated, e.g., turned-on, the high pressure nozzle 24 which receives a high pressure flow through lines 22b to create a high pressure spray 19 into the containment chamber 20. The high pressure spray 19, in one preferred embodiment, has a pressure between 30 pounds per square inch (p.s.i.) and 2500 p.s.i. In another preferred embodiment, the high pressure spray 19 is between of 100 p.s.i. and 2500 p.s.i. The high pressure spray 19 breaks up the solids, such as toilet paper, refuse, etc, that enter the containment chamber 20.

A left side view of a spiral flow completing structure 32b of the hygienic apparatus 4 is shown in FIG. 5A and a rear view of a spiral flow completing structure 32b of the hygienic apparatus 4 is shown in FIG. 5B. The spiral flow completing structure 32b connects between the chamber outlet 21b and a drain tube 29. An incline ramp 32a preferably connects the spiral flow completing structure 32b to the chamber outlet 21b. The spiral flow completing structure 32b is sized to contain a sufficient amount of liquid and broken-up solid waste to draw any liquid and broken-up solid waste remaining in the containment chamber 20 from the containment chamber 20 at the completion of a flushing cycle. The high pressure flow 19 is approximately parallel to the chamber floor 20a and is preferably between approximately 1/16 inches and approximately ⅜ inches above the floor 20a and more preferably between approximately 1/16 inches and approximately ¼ inches above the floor 20a.

A first embodiment of the spiral flow completing structure 32b comprises a spiral of approximately one inch to approximately one and one half inch diameter tubing, and is suitable for the hygienic apparatus 4 when the high pressure nozzle 24 is fully functional and provides the high pressure spray 19 to break-up solids. A second embodiment of the completing structure 32b comprises a spiral of approximately two inch to approximately two and one half inch diameter tubing, and is suitable for the hygienic apparatus 4 when the high pressure nozzle 24 is not functional and a low pressure spray of water (household water pressure) is used to fill and flush the hygienic apparatus 4 using a higher volume of water (see FIG. 15), for example, when electrical power is not available to the pump 10). The completing structure 32b may be constructed from PVC pipe, although it will be apparent that any number of other materials may be used instead or in conjunction with the PVC and the completing structure 32b may be manufactured of a rigid, semi-rigid, or flexible single or composite material.

The completing structure 32b in combination with the flowing liquids and solids form a vacuum which increases a velocity of the solids and liquids through the completing structure 32b. This increase in velocity and selection of pipe diameter takes advantage of the molecular attractive properties of solids and liquids to realize an increase suction device. Thus, the completing structure 32b reduces the need for additional water, such as those required by gravity-powered toilets to push the solids and liquids toward the drain tube 29. The completing structure 32b in combination with the flowing liquids and solids form a vacuum that increases a velocity of the solids and liquids. Thus, the completing structure 32b reduces the need for additional water, such as that required by gravity-powered toilets to push the solids and liquids toward the drain tube 29.

In an alternative embodiment, the nozzle 24 may be replaced by a main nozzle and a secondary nozzle where either one or the other may be used for different purposes, for example, one could be for applying soap and the other providing rinse water.

In contrast to standard or low flow toilets, the nozzle 24 directs the high pressure spray into the containment chamber 20, which chamber 20 has a shaped portion for holding the solids and liquids. The cooperation of the high pressure spray 19 and the chamber 20 provides an improved hygienic system which breaks-up solids, prevents splashing during breaking-up process, and moves both solid and liquid particles from the chamber 20 into the completing structure 32b.

An advantage of the hygienic apparatus 4 as compared to prior art toilets which utilize one and a half (low-flow) to three gallons (standard flow) of water, is that the high pressure nozzle 24 with the aid of the pump 10 requires only approximately one sixteen to one eighth of a gallon of water, thereby greatly conserving water. Furthermore, the exemplary embodiment of the present invention remains cleaner than know toilets because pre-wetting the inner surface 28a by spray jets 26 reduces or prevents build and stains on the inner surface 28a, thereby reducing the fluid required for reducing or preventing incidental solid or liquid build-up on the inner surface 28a. Furthermore, in contrast to conventional standard toilets, the hygienic apparatus according to the present invention requires no rubber or other seal to store water in a toilet tank. Thus, this system does not depend on the integrity of any seal to prevent fluid leakage and therefore waste.

A right side view of the hygienic apparatus 4 shown in FIG. 6 identifies details A and B. Detail A showing the spray jets 26g is shown in FIG. 7. In one embodiment, the spray jet 26g has a tapered construction comprising an input port 27a and a reduced cross-section slotted output orifice 27b. The slotted orifice 27b, in this example, a smaller cross-sectional area than the input port 27a.

Detail B showing the high pressure nozzle 24 is shown in FIG. 8. The high pressure nozzle 24 includes an input port 24b and a reduced cross-section output orifice 24a. The nozzle 24 is further shown in detail in side view in FIG. 9A, in top view in FIG. 9B, and in front view in FIG. 9C.

FIG. 10 illustrates a block diagram for a hygienic system apparatus in accordance with an embodiment of the present invention. Switches 40-44 (S1-S4) are part of a user-sensing unit. The user sensing unit may be stimulated by a variety of activities by a user, e.g., lifting the toilet seat, closing the toilet seat, or sitting on the toilet seat (see FIG. 2A for positions of switches 40 and 42). Electrical or mechanical interlocks may also be provided such that certain operations or actions are allowed or prohibited depending on the state or status of various of the components. Moreover, other sensing apparatus (such as infrared or ultrasonic motion or position sensors of the type well known in the electronic arts) may be used to enable, or disable certain components, and/or activate or terminate certain operations.

In the illustrated embodiment, upon opening the toilet lid, e.g., switch 40 (S1) closes, and sends an electrical signal to a module 46. The module 46, in this example, is an electronic switch array, which could be part of a central processing unit (not shown), that activates or deactivates the pump 10. In an alternative embodiment, the module 46 may be a mechanical array that directs which sprayer(s) or nozzle to activate.

For instance, the module 46 may deactivate the pump 10 selected times of a day. For example, the pump 10 may be deactivated in the evening hours, during sleep time, or when no one his home to conserve energy and minimize any noise originating from the pump. Furthermore, the module 46 activates or deactivates valves 50a-e (V1-V5). The valves 50a-e may have a valve member, e.g., that opens and closes, for selectively pumping fluid originating from the pump 10 to a location within, on, or outside of the hygienic apparatus.

For example, if switch 40 (S1) closes, control module 46 activates value 50a (V1) to transport fluid to spray jets 26h-26k. The spray jets 26h-26k spray fluid from the toilet rim onto an interior surface of the toilet bowl 28. The spray fluid for the spray jets 26h-26k may originate from water from the city line 57, recycled water 49, and recycled water from a tank 55. In an alternative embodiment, the recycled water from a tank 55 may come from other water usages, such as shower water, bathroom sink, laundry room basin, storm drain, home gutter, or the like. Thus, water may be utilized from other activities, e.g., recycled, near or from devices connected to the hygienic apparatus 4. As compared to conventional hygienic systems, such as the standard toilet, this system has the advantage of saving water not only by economizing usage by having a “low flow” design, but also by reusing previous used water for the purpose of toilet flushing or rinsing.

In addition, because the hygienic apparatus 4 in this example flushes upon being closed, cleanliness will be improved because during a flush, the toilet lid or cover 5 will prevent backsplash from solids and liquids becoming airborne and landing on individuals or the adjacent environment.

Finally, nozzles 24 and 60, and spray jets 26h-26k may be independently controlled, e.g., activated or deactivated, and additional water savings results because the spray jets 26h-26k may be activated only when necessary, e.g., depending on the solid and the liquid deposited, as compared to conventional standard toilet having the same flush independent of the solid and the liquid deposited. Furthermore, cleaning enzymes or other substances may be added to the recycled water tank so that the hygienic apparatus may be utilized to clean the toilet 28. The valve 50c (V3) controls the high pressure flow to the high pressure nozzles 24 and 60 so that the resulting high pressure sprays are correctly timed (see FIG. 19).

In yet another embodiment, valve 50b (V2) is opened so that handheld nozzle 52 may be utilized. For instance, handheld nozzle 52 may be used to clean other surfaces or structures, such as shower door, shower wall, bathtub, sink, floor, and the like. After the solid and the liquid are deposited in the containment chamber 20 (see FIG. 3), the toilet seat 5 is closed. The closed toilet set 5 causes switch 43 (S3) to close and nozzle 24 becomes activated. When activated, the nozzle 24 sprays fluid to break-up solids and transport both solids and liquids from the containment chamber (see FIGS. 5A and 5B) toward the completing structure 32b. Furthermore, if the pump 10 malfunctions, the pump will pass water at approximately the input pressure level, e.g., such as regular pressure from the city line, approximately 50 p.s.i. in this example (see FIG. 15). Thus, the hygienic system 4 functions even when the pump 10 fails.

A second embodiment of a completing structure comprising a vertical loop 70a and tube 70b are shown in FIG. 11 connected between the ramp 32a and into the drain 29. The diameters and lengths of the loop 70a and tube 70b are selected so that sufficient liquid and broken-up solid waste will be held in the vertical loop 70a and tube 70b at the end of a flush cycle to draw any remaining liquid and broken up waste in the containment chamber 20 from the containment chamber 20 to complete the flush cycle. The extended pipe 70c, in one embodiment, increases the velocity of solids and liquid flow by increasing pressure flow, for example, for masses originating from the pipes 70b and 70c. The arrows illustrate a fluid flow from representative spray jets 26 and representative high pressure nozzle 24 for the solids and liquids that pass through the containment chamber 20 to the drain tube 29.

The tube 70b preferably extends into the drain tube 29 between approximately 2 feet and approximately 5 feet. A first embodiment of the vertical loop 70a and tube 70b comprises tubing of approximately one inch to approximately one and one half inch diameter tubing, and is suitable for the hygienic apparatus 4 when the high pressure nozzle 24 is fully functional and provides the high pressure spray 19 to break-up solids and pushing the liquid and broken-up solid waste from the chamber 20. A second embodiment of the vertical loop 70a and tube 70b comprises tubing approximately two inch to approximately two and one half inch diameter tubing, and is suitable for the hygienic apparatus 4 when the high pressure nozzle 24 is not functional and a low pressure spray of water (household water pressure) is used to fill and flush the hygienic apparatus 4 using a higher volume of water (see FIG. 15), for example, when electrical power is not available to the pump 10). The loop 70a and tube 70b may be constructed from PVC pipe, although it will be apparent that any number of other materials may be used instead or in conjunction with the PVC and the loop 70a and tube 70b may be manufactured of a rigid, semi-rigid, or flexible single or composite material.

In yet another alternative embodiment, an external pipe, for example a plastic rigid or flexible pipe, may replace the loop 70a and tube 70b. The external pipe has a preferred diameter selected from a range between approximately one inch and approximately 1.5 inches. The external pipe, in one preferred embodiment, has one portion that extends into the drain tube 29, similar to the tube 70b. The extension of the external pipe is, in one preferred embodiment, between one foot to 5 feet. Furthermore, the external pipe also has a curved portion (e.g., a winding portion) afterwards partially straightens to mate with an chamber output 21b of the containment chamber 20. The external pipe may be detachable so that clogs may be easily removed and afterwards the external pipe then reattached. The external pipe diameter of between approximately one inch and approximately 1.5 inches is chosen increase solid and liquid suction so that the broken-up solid masses and liquids may readily transport to the drain tube 29. The suction increase results in part due to the molecular attraction of liquid and solid particles deposited in the containment chamber 20. In yet another variation of this embodiment, a sink output drain, not shown, may be connected along the sewer line proximal to the drain tube 29. In this alternative embodiment, discharge from the sink may further increase velocity of liquids and solids that enter the outlet port.

An embodiment of the hygienic apparatus 4″ including a second high pressure nozzle 60 for creating a spiral flow 62 inside the toilet bowl 28 is shown in FIG. 12A in side view and in FIG. 12B in top view. The high pressure nozzle 60 is mounted just below the rim 9 and produces the spiral flow 62 tangential to the bowl inner surface 28a and preferably with a slight down angle. The nozzle 60 is aimed to result in a spiral flow 62 of just over one revolution before the spiral enters the containment chamber 20. Because the flow 62 may be high pressure and potentially dangerous to children or even adults, a guard 64 may be placed over the nozzle 60 to prevent fingers from being places directly in the beginning of the flow.

A cross-sectional view taken along line 13-13 of FIG. 12B of the hygienic apparatus 4″ configured for the spiral flow 62 is shown in FIG. 13. The left side of the bowl 28′ is biased inwards by an offset O1 to help direct the spiral flow 62 as the flow 62 originates from the nozzle 60. The offset O1 is preferably approximately 1.5 inches.

A second embodiment of the hygienic apparatus 4′″ including a plurality of high pressure nozzles 60a-60d producing a plurality of spiral flows 62a-62d is shown in FIG. 14. The hygienic apparatus 4′″ is otherwise similar to FIGS. 12A and 12B.

An embodiment of the hygienic apparatus 4 including a manual flushing feature is shown in FIG. 15. A low pressure, high volume nozzle 66 resides inside the bowl 28. The nozzle 66 receives a household water flow 70 at typically 50 PSI controlled by a manual valve 68. If the pump 10 fails, or power to operated the hygienic apparatus 4 is lost, the hygienic apparatus 4 may be flushed using the manual flushing feature. In this case, larger diameter completing structures are recommended for proper operation.

Standard and secondary sewer traps 74 and 76 of the hygienic apparatus 4 are shown in FIG. 16. The standard sewer trap 74 is created by residual water in the containment chamber 20 and tube 32a. The secondary trap 76 may be provided by incorporating a raised exit portion 78 following the spiral completing structure 32b or the loop 70a to trap water in the tubing. In either instance, the trapped water prevent vapors backing up from the drain 29 and causing odors.

FIG. 17 is an illustration of a means and method of transporting the hygienic apparatus 4 in accordance with an embodiment of the present invention. In this embodiment, a hygienic apparatus 4 is transported using a dolly 72. FIG. 8 shows that the hygienic apparatus 4 is transportable and has an drain tube 29 that mates with an output port of a standard toilet. Thus, the hygienic apparatus 4 has been adapted to fit within the standard footprint created by a standard or low flow toilet. The dolly 72 may be specially adapted to fit the apparatus 4, or alternatively the apparatus 4 can be designed to have a substantially standardized shape or profile, such that a one-size-fits-all type dolly 72 can be used without special adaptation.

A method 200 according to the present invention is shown in FIG.18. The method 200 includes depositing waste material comprising liquids and solids in a containment chamber (S202), spraying a high pressure spray into the containment chamber to break up the solids (S204), pushing the liquid and broken up solids from the chamber to generate an outlet flow in a outlet pipe (S206), and sufficiently containing the outlet flow in the outlet pipe to draw the remaining waste material from the chamber (S208). The method 200 may further include a first step of pre-wetting the inner surface 28a of the toilet bowl to prevent waste material from sticking on or staining the inner surface 28a.

A time-line for operating the hygienic apparatus according to the present invention is shown in FIG. 19.

A top view of the hygienic apparatus according to the present invention a right side view of the hygienic apparatus according to the present invention with dimensions is shown in FIG. 20B. The rim 9 is approximately elliptical with an minor inside diameter D1 of approximately 11 inches and a minor outside diameter D2 of approximately 14.5 inches. The outside length (or major diameter) L1 is approximately 16.5 inches. The competing section 70a has a height H1 from the floor of approximately 8 inches, The chamber floor 20b has a height H2 from the floor of approximately 4 inches, the chamber ceiling 20a has a height H3 from the chamber floor 20b of approximately 2 inches, and the rim 9 has a height H4 from the chamber ceiling 20a of approximately 8.5 inches.

A detailed side view of the chamber 20 is shown in FIG. 21A, and a detailed end view of the chamber 20 is shown in FIG. 21B. The chamber 20 has a length L2 which is preferably between approximately one inch and approximately seven inches, and a diameter D3 which is between approximately 1.5 inches and approximately 2.5 inches, and the may be elliptical.
