Air flush system
A system and apparatus for reducing the amount of water required for flushing toilets. The system flushes a toilet containing a small amount of water in the bowl with air forced into the bowl from a special airtight lid and a vent in either this lid or in the toilet bowl area. While holding down the airtight lid, injected air from an air pressure device connected to the vent flushes the toilet, using minimal water as compared with conventional toilets. Afterwards water is added to the toilet bowl to reseal the trap and ready the toilet for the next use. By allowing this same air pressure device to produce suction as well as air flush, it will also function as a dry plunger in the event of a blockage and because this system uses air rather then water for flushing the swear pipe is predominately filled with air preventing freezing of pipes. It also will give a long flush capacity for those systems that enter a cesspool or septic tank.
The air flush system is directed towards being an accessory for existing toilets as well as being a new complete system for reducing the amount of water required for flushing a toilet. It also provides a stronger flushing ability, compared with current competitors. By injecting a predetermined amount of compressed air into the toilet bowl area, the toilet will flush, using far less water than a conventional toilet. And can leave the conventional water capability of the toilet operational. This system, which can be as inexpensive as buying a new seat for the toilet will save it cost in water in a short period of time. Air flush system is also far safer then the vacuum toilet system that have sucked a person's arm in and the cost of a vacuum toilet system is enormous compared to this air flush system and the maintenance to a vacuum system is potential as enormous as its initial instillation cost.
Air flushing is achieved by the use of an airtight seat and lid unit and a vent hole so as to inject air into the bowl area. Then air pressure can be vented into the toilets airtight bowl area. The mechanism least obtrusive to the normal functioning of the toilet uses what is called an “independent lid” that will be placed under the conventional seat after the toilet has been soiled and is ready to be air flushed. The seat will be closed down over the lid with an air pressure device coming through the hole in the seat then the seat is pressed down thereby pushing the independent lid against the bowl rim to assure air tightness, compressed air is vented into the bowl area by a hole in the cover. Then by way of a vent hole in the lid a predetermine amount of air is injected into the toilet bowl area there by air flushing the toilet. Another more permanent option to the independent lid is modified conventional seat and lid unit meaning having gaskets and a vent hole
This modified now an air flush seat lid unit will be is attached to the toilet to become part of it. And air flush mechanism will virtually be undetectable as it will have a lid over it that conforms lid it is mounted on making it convenient to use and in most cases, the flush is so powerful that in the flapper valve in style toilets the flapper well needed to be weighted down by a bag of coins or such and this weight will also make it possible to use the flush leaver as a water control and a flush would only occur when the lever is held down. And the toilets which don't have tanks are virtually pre made to be converted into air flush toilets.
These aforementioned minimally obtrusive designs work perfectly well and offer the advantage of leaving available the normal water-flushing function of the toilet. If water is available there are many ways of have the clean water run while the air flush is taking place this will help to clean the bowl walls and add disinfectant to the bowl area water.
SUMMARY OF INVENTION AND OBJECTSThe air flush system works on existing toilets as an accessory. It also works on toilets that don't have water-tanks or water supplies, Therefore, locations currently using outside latrines can use the system and in many cases, can now have an air flush system toilet installed inside the house because the system is so powerful that a good safety distance can be achieved between the cesspool and the house. This will help put an end to cholera and many other types of epidemics that are directly a result of lack of latrine management. Said crisis can be averted by the system set forth herein.
Therefore, a special toilet has been designed that will initially be an inner-liner and after installed in a location can be reinforced with concrete. This site toilet will eliminate the need for a hard floor as the weight and large base will make it stable, and this site toilet will also give the opportunity for the sewer pipe fitting to come out the back or side making it easier to give the pipe a downward angle of flow. This advantage of having the sewer pipe being able to be above ground is facilitated by the sewage pipe being filled mostly with air rather then water so the pipe is freeze-proof especially in comparison to the fragile plaster toilet. Also, by having the sewer pipe exit out the back rather than the bottom of the toilet, the system will eliminate a hard right angle from the journey and if the toilet is placed on a pedestal like blocks or in a built up dirt box then the downward slope is increased, diminishing the amount of wash water even further.
In the past, in cold climates the sewer pipes must be buried under the frost line. But with air flush system, the pipe can run above ground saving untold maintenance and installation cost. When the temperature is below freezing and the toilet in not in use there is only a minimum amount of water left in the trap area and it is not threatened by the freezing. As there will be a flexible coupling between the site toilet and the sewer pipe, it will make it possible to have the pipe descend to the cesspool on an incline. This flexibility will also make it possible to change the location of the cesspool by just moving the pipe direction.
This air flush system is further directed for use within the confines of relatively compact units, such as multiple expeditionary lavatories on planes, boats and trains. Air flush will also solve the problem of low septic-tank capacity, as it has been the large volume of water from water flushing that has been the major part of the overflow problem.
With air flush, the primary part of the waste is simply air, thereby reducing the waste storage capacity problem by as much as 80 percent. Therefore, the system would require much smaller septic tanks and by eliminating the tank section from the toilet, it would save up to 50 percent on the purchasing cost and shipping cost of individual toilets. In addition, if the site toilet inner-liner is used the savings can reach up to 95 percent and the fact that porcelain toilets shatter in shipping, it creates a need for this site toilet liner concept.
An alternative to replacing or modifying the attached seat lid unit would be an independent lid which is very mobile because it is not attached to the toilet. It is only placed over the toilet bowl rim when the attached seat and lid are in the up position.
FIRST EMBODIMENTSA round accordion bellows eight inches in diameter and 12 inches long is a good multipurpose air pressure device that can easily be mounted on the air flush lid with a vent hole passing through, so it can inject a predetermined burst of air, thereby air flushing the toilet. The bellows can have valves with both intakes on the top and the big exhaust hole to the blow area can also be exited valve so as to pump air for an automatic double flush capability. Or it can not have any valves so it can have a sucking ability that will help it make a really strong flush by starting with the bellows being about halfway inflated before pressing down the lid airtight to the bowl rim. Then by pulling up the bellow's handle the water in the toilet's trap will be brought up into the bowl, immediately pressing down the bellows to easily flush with no resistance from water in the trap. In fact, the air in the trap will have a small vacuum so as to suck the waste out. And if a double air flush is needed then just lifting the lid a crack can let in air.
This sucking ability also enables the bellows to be used as a “dry plunger” by pulling up and pushing down on the handle it will shake a blockage free and on an independent lid extra control can be achieved by closing the seat section over the bellows, which will go through the seat's center sitting hole and then the seat can be used to hold the bellows down while plunging. This eliminates the threat of bacterial contamination from fecal matter in a toilet area that results when using instruments such as a submergible plunger or snake
Furthermore, this bellows will also function as an “air-pressure-gauge” as it can measure the flow aspect of the sewer pipe. Gauging the resistance of the flushing stroke by noticing if it gets harder to press down and if the bellows starts to pressurize more the usual can indicate to a user that the swear-pipe may have a blockage starting to materialize. Then a preemptive clearing can be performed by water flushing the toilet or even adding drain-cleaner.
If a blockage occurs that is too concentrated for the bellows to blow through then there are better air pressure devices for plunging, such as the cylinder with piston model or the diaphragm model, both of which have professional power abilities to open deep pipe blockages. With these more powerful drain busters a gauge will be mounted on the lid that will have a fitting for a more accurate calculation.
Because the accordion bellows is collapsible, it is appropriate for permanent mounting on the attached seat and lid unit. Its ability to become flat makes it possible for the lid with the bellows mounted on it to be put into the up position. This flatness feature also makes the bellows the most cost efficient for storage and shipping. Another advantage is its extremely lightweight.
BRIEF DESCRIPTION OF THE DRAWINGSAdditional objects and advantages of the Air Flush system will appear from the following description and parts list in conjunction with the accompanying drawings.
The most important part in the air flush system is that it is a modification of preexisting toilet facilities as (
One such lid is called “the vented independent lid” (See
Beside the independent lid and the mounted air device seat and lid units there is another model air flush seat lid unit (See
Both these seat and lid units (26) will come in two distinct sizes—not interchangeable. However the air flush independent lid (24) will accommodated both size toilet seats by having an extra large gasket (24a) that wraps around its bottom surface edge that comes in contact with either size toilet bowl rim (28) and will work with a unmodified conventional seat including the horseshoe type with open front (
During air flushing with all three-lid models (24, 26, 30) the lid must be pushed down onto the bowl rim (28a) so the bowl area (28) is airtight. Then compressed air can be injected, causing the toilet to air flush. There are many kinds of air pressure devices (SHEET 6,7,8,) all of them must be vented into the bowl area so to air flush the toilet. This accordion style bellows (22) shown here (
For both the independent lid (
Another model air flush lid (30) is a conventional toilet seat and lid unit which has been modified air tight with the same kinds of gaskets (30a and b) but the lid does not have an air-pressure device mounted on it or even a ventilation hole going through it. Instead, it works with conventional toilets that have been modified to have air pressure devices connected to their toilets bowls' flush hole s (
There is a way of adding water during the air flushing the easiest is to use a metered flapper vale (52) which consists of flapper with a hole in its float area and a chain coming from it and on the chain is a float (52b) which will give control of the amount of water when the flush lever (53f) pressed and released this will only release just the amount of water to air flushing so water will be going into the toilet as the air flush occurs this will let enough water in to wash the toilet wall and refill the bowl for the next usage. The metered flapper is made so if the water release lever (52f) is held down the toilet will release water into the bowl and flush it with water, this will also enable the toilet to be used in the conventional water flush way. And the conventional hydro switch used on toilet without water tank can be adjusted to give the right amount of water to add and clean an air flush.
A more elaborate way to have water running during air flushing is seen in (
A more elaborate way to help the water run into the over flow tube during the air flush would be a one-way valve (
In all three of these lid models (24,26,30) the option of using line water to help clean the walls of the toilet during air flushing can be done by a couple of different ways. In all of cases water will need a special bowl water line (48) to send water into the bowl water flush hole (40). This done by having the main water line valve (48) always on power by a 12 volt transformer rectifier (48c) the water line as well as the 12 power is connected to anti-siphon water control solenoid valve (48a) that is activated by a timer (48b) that will send water through toilet water in line (48d) to the bowl area during the air flush this predetermined amount of water will run long enough to the refill bowl area for the next usage. The float valve (50b) is set now to be always on The water control valve (48a) will be switched on either manually when there are no automatic components by just turning on the main water valve (48) before air flushing and tuning it off after the bowl area has been refilled. Or this can be done automatically with the use of the aforementioned power units by pressing a button (48f) which is handedly mounted on the toilet preferably the near or on former water flush handle (52f) location and is pressed right before activation the air pressure device.
More intrusive way to air flush (
And clean water can be add to the air flush by having tube (44) connected to the and controlled by a water dispenser switch (48a) Water can then be dispensed in a predetermined flow at a controlled rate and time. Therefore, all the water dispensing devices that is, the flow valve, the overflow tube and the flapper are now rendered useless.
The vent coupling (42), which has a two-inch inner diameter hold, will have inserted into it tubing measuring 5 inches long with a slightly less then a two inch outer diameter so it can be put inside the flapper socket of the coupling. This tube (58) will be sealing plug (58) on there would also be a fitting to connect the water line (48b) to this tube to run water into the bowl area when the water line is on.
Then the vent coupling (42); which has a two-inch inner diameter hold, will have inserted into it tubing measuring 14-inch long and slightly less then a two inch outer diameter (44). The tubing has on its both ends sealing gaskets (44a) for the air pressure device (22). A new tank cover (38c) is needed to gain access to the vent tube (44) by the air pressure device.
There are many ways to make the compressed air burst the is needed to air flush the toilet a good first embodiment is a bellows as their construction goes back dating to the Bronze Age. The construction of the bellows (24) is show in (
Either way once the bellows is connected it is set in a halfway up position and then the lid is held down making the toilet airtight. To air flush first pull up on 26 the handle of the bellows to suck up the water in the trap into the bowl area then when getting the bellows to the top expanded position immediately push down the bellows till it is flat this will maneuver clear the trap and second push out all the waste that was in the toilet easily as there will be no resistance from water in trap. The air will be a predetermine amount to flush the toilet with air into 46 the discharge pipe. This sucking ability of the bellows makes it possible to use it for a dry plunger by just going up and down on the handle will free the trap area from an overload of paper or the like. And by judging the force it take to push down the bellows it will give an idea of how clear the deeper swear pipe's condition is.
Other air pressure device which are favorable because they can reversible meaning they can suck as well as blow air are 66 square bellows which can be made with easy to get materials cut into layers and taped together, 68 piston pump which is constructed with a metal cylindrical container like a pretzel can, the bottom of which has the 60 ventilation hole in it that goes through to the bowl area and the cover (68) has holes in it, one hole is for a piston rod and three others for breathing. The piston rod goes through the cylinder cover and is connected with a strong 68f screw to a layer of materials making up 68b a piston 68c,d,e, made with to disks with ring material sandwiched between them. Another kind of powerful plunging type of device is the 70 diaphram having a outer drum 70a where in it is a disk 70b with a handle on it that has connected to it a 70c rubbery martial which is airtight connected to the toilet lid by going under the drum, Another and type of air supply device which can not suck but will air flush a toilet is 72 old fashion bellows and another way is to make 74 the seat and lid into a bellows
The next air pressure devices use electrical power 76 is a power centripetal force blower it is shown here with the low voltage switch 80 and the 106 transformer box relay but it will work will with the switch on the blower 67 which is a power centripetal force blower. A special 88 push button power switch is introduced that will be activated by pushing down on it and as it will be on the lid this pushing will also hold the lid airtight. The button will turn on 106 the timer box that will send high voltage to the 100 air pressure device which will pressurize 102 the air booster unit which can store compressed air till it reaches its capacity which will then trigger 104 the pressure release unit which is connected by way of the 96 coupling to connect the toilet's lid with the air pressure device this coupling will making a right angle 90 degree angle so the lid and coupling will be flat so the lid can be put in the up position and still remain connected to 98 low pressure vacuum cleaner hose or the like.
There are many ways to have one air pressure device service multiples toilets one is a 108 distributor which is a mechanical way of having multiple toilets being supplied by one air device 108a is a stepping motor or a manual ratchet to control which toilet has just pressed the button 108b is the rotor with vent pipe inside 108c is the coupling to the air supply. The 104 pressure sensitive relay box which releases the air when the pressure is sufficient 110 elastic or even metallic spring to control air pressure, 112 tee fitting 102 booster and a pressure control box 106 power timer and switch relay box, 106a transformer 110 vac to 24 vac and 106b timer for air flush duration and 106c relay for lid press switch 114 air compressor 116 high pressure line 118 high pressurized Air supply tank 120 multiple toilet manifold 124 regulator to bring down high pressure to booster amount 128 butterfly or door valve having high volume low pressure relay which sends the air to the toilet by releasing valve trigger for butterfly or door valve.
