Abstract

An improved toilet flushing system includes a cylindrical water receiving container into which flush water is inserted through an inlet valve; a float operating within a float bowl, said float chamber being connected in fluid connection to said cylindrical holding vessel, said inlet valve being opened and closed in response to the water level within said cylindrical holding vessel; and a displacement plate rotatably connected to an axis within the cylindrical water receptacle to displace any desired proportion of water from the cylindrical water receptacle into the bowl corresponding to a degree of rotation.

Description

Improved toilet flushing system

Technical Field

The present invention relates to toilet or urinal flushing systems.

Background

The most common toilet flushing systems used today have the following disadvantages to be solved.

● The toilet is prone to water leakage.

● Unless closely attended, small amounts of water leaking from the cistern into the urinal or urinal are ignored.

● There is no visible or audible alarm when water leaks from the flush bowl into the urinal.

● Water leaks are often overlooked due to user carelessness or economic limitations, resulting in wasted water.

● There are only two options, half or all, regarding the amount of flush water dispensed into the bowl.

● The water usage per flush is reduced by government-imposed water usage limits, which reduces the efficiency of the flush.

● Due to the temperature difference between the tank and the surroundings, condensation (sweating) occurs on the toilet tank, whereby the condensate drains to the floor, resulting in bad water.

● Replacement of a failed component is often expensive due to the cost of the component and/or the cost of professional labor.

● When actuated by unclean fingers, the flush handle can become contaminated.

Disclosure of Invention

The invention is based on 'failure mode and impact analysis' FMEA for short, a tool used in the design and manufacturing industry. Accordingly, the components of a typical toilet flushing system were analyzed. Toilet flushing systems commonly used today consist of a cistern, a flush valve operated by a lever and a fill valve controlled by a float.

Failure mode and impact analysis is performed on the components that fail resulting in water wastage:

a flushing valve: a valve with a flapper and a seat is typically located at the bottom of the tank. The flapper valve leaks water due to degradation of the material or physical deformation or entrapment of foreign matter between the sealing surfaces.

A water inlet valve: leakage due to deterioration of the seal or joint.

In the present invention, a backup valve located upstream of the fill valve shuts off the water supply if the fill valve continues to allow water to pass through after being fully closed.

A floater: it is the responsibility of the user to install the float. Any error in the mounting or flexing of the float rod will cause the reservoir to overflow into the bowl. Overflow of the reservoir is likely not noticed.

The present invention provides a toilet flushing system that solves the above problems.

The invention comprises the following steps:

eliminates a sealing baffle which is easy to leak between the water tank and the urinal;

preventing further water leakage with the water in the leak;

an alarm is generated when a leak (problem) occurs.

Allowing the user to reset the system to fill the reservoir at each flush after the water flow to the system is shut off.

In the event of a water leak due to the inconvenience of resetting each flush, the user is prompted to take action early.

Can be added to the existing conventional toilet flushing system; eliminating condensation on the surface of the tank as occurs in prior systems;

can be installed at a higher elevation than the ceramic jar, which fits just on top of the urinal.

Higher water increases the rate at which water enters the bowl, thereby better flushing the bowl surface.

This is particularly true when the amount of flush water is limited,

allowing more than one reservoir to be used to eliminate the wait time between flushes, or if additional water is required for a flush, (allowing more than one reservoir to be used to eliminate the wait time between flushes as well);

allowing any fraction of a full flush or partial flush compared to the half flush or full flush capability of existing flush systems;

may be operated by an electronic control system including touch-less operation.

Prior Art

Today's toilet flushing systems do not provide a comprehensive solution.

Only the double flush mode is available for conserving water. The present invention allows any desired amount of (water) to be used, rather than half or all of the dispensing provided by a dual flush. The dual flush option requires a separate system, which is not required by the present invention. Patents that teach techniques to shut off water flow in the event of a leak leave the user in a dilemma of being unable to flush because they do not teach a method of disabling an intermittent override flushing system.

There is currently no toilet flushing system that eliminates all failure modes and is both economical and effective.

Toilet flush systems that do not use flapper valve systems siphon flush water into the bowl.

In summary, none of the known toilet flushing systems are completely leakproof.

In one embodiment:

fig. 1 is a perspective view of a cylindrical water receptacle flushing system 20 mounted in liquid flow connection over a toilet bowl 10.

Fig. 2 is an exploded view of the cylindrical water-receiving container flush system 20. The water supply to the flushing system is established by means of a connector 21 connected to a normally open main valve 22. A normally open inlet valve 23 is connected downstream of the main valve 22. The inlet valve 23 discharges water into the filling chamber 24, and the filling chamber 24 flows into the cylindrical water receiving container 25 through the open passage 26. During a filling operation, the inlet valve 23 discharges a small stream of water through a branch pipe (not shown) into the toilet bowl 10. It is clear that the cylindrical water receptacle 25 and the filling chamber 24 are maintained at the same level during the filling operation. The fill valve float 27 is attached to the fill valve 23 in a manner that opens and closes the fill valve 23. Inlet valve float 27 moves up and down in filling chamber 24 depending on the water level in filling chamber 24. When the water in the inlet valve 23 reaches a set level, the inlet valve float 27 will completely close the inlet valve 23. When the water in the filling chamber 24 reaches a set level, the inlet valve float 27 completely closes the golden valve 23. The connection between the fill valve float 27 and the fill valve 23 can be adjusted to establish the fill level to a desired limit. Adjusting the connection between the inlet valve float 27 and the inlet valve 23 can bring the water level to a desired limit. The system is now ready for a flushing operation. During a flushing operation, water from the cylindrical water receiving container 25 is discharged and directed into the toilet bowl 10 through the flush water discharge port 31.

A shaft 28 inside the cylindrical water receptacle 25 supports a shifting plate 29. The shifting plate 29 rotates on the shaft 28. The bottom end of the shifting plate 29 sweeps across the bottom of the floor of the cylindrical holding tank 25. The side edges of the displacement plate 29 sweep over the cylindrical wall of the cylindrical water receptacle 25. The bottom edge of the fixing plate 30 is located at the bottom plate of the cylindrical water-receiving container 25 and one of its vertical edges is attached to the cylindrical wall of the cylindrical water-receiving container 25, the other vertical edge of the fixing plate 30 being very close to the axial portion of the shifting plate 29. The orientation of the fixing plate 30 and the displacement plate 29 within the cylindrical water receptacle 25 and the flushing operation are illustrated in fig. 3, 4 and 5.

Figure 3 shows water flowing through the valve into the filling chamber 24 and via the passage 26 into the cylindrical water-receiving container. The water flow stops when the set water level is reached. In fig. 1, one end of the torsion spring 32 is attached to the tank cover plate 33, and the other end is attached to the displacement plate 29.

Fig. 3 also shows the system ready for a flushing operation when the shifting plate 29 is oriented in its original position by the torsion spring 32. The flushing operation is performed by rotating the shifting plate 29 from its original position. The volume space defined by the fixing plate 30 and the displacement plate 29 and the cylindrical wall in the inner cross section of the angle α is defined as the space α, and similarly, the space occupied in the angle β is identified as the space β.

Fig. 4 shows the rotating displacement plate 29, thereby increasing the space α and decreasing the space β. The increase of the space decreases the water level in the space, and the decrease of the space increases the water level in the space. When the space β is reduced during the rotation of the displacement plate 29, water overflows into the discharge port 31. It is necessary that a small amount of water penetrates into the space alpha through the gap between the plate and the wall. No water flows between the spaces above the top edges of the fixed and shifting plates.

Fig. 5 shows that the shifting plate 29 is rotated very close to the end position where the angle alpha is very small and as high as possible. Most of the water in the space β has overflowed into the bowl. After this stage, the displacement plate 29 is restored to the original position by the torsion spring 32 as described previously.

Partial flushing: the advantage of this flushing arrangement is that any amount of water in the space p can be discharged. In fig. 1, the flush handle 34 on the displacement plate 29 is hovering over a dial plate 35 on the tank lid plate 33. The user, guided by the dial 35, can rotate the flush handle 34 to dispense the required amount. It saves water as it avoids excessive water usage for small flush requirements.

Leakage prevention: a leak is defined as any uncontrolled flow of water into the water receiving container. Leakage may occur for a number of reasons, including inaccurate inlet level settings, leaking connections between valve bodies, incomplete closing of the inlet valve, inability of the inlet float to float, etc. In fig. 1, a drain chamber 36 is established below the main valve 22 and is separated from the filling chamber 24 by a diaphragm 37. The primary float 38 is attached to the primary valve 22 and the primary float 38 moves up and down to close or open the primary valve 22, respectively. Water flows into the receptacle 36 from just above the leakage chamber 36 and above the top edge of the partition 36. Increasing the water level in the drain chamber 36 raises the primary float 38 and completely closes the primary valve 22. The system is shut down until there is no water, and once the leak is corrected, the water in the leak chamber 36 can be drained and the master valve 22 can be opened for normal operation. In fig. 6, there is shown an inlet water level for the receptacle 90, an overflow level 91 across the partition 37 and a flush water discharge level 92 above the cylindrical receptacle 25. It should be noted that the discharge level 92 is only reached in the space β shown in fig. 3, 4 and 5, which is isolated from the filling chamber 24. This is to ensure that flushing water does not enter the drip chamber 36.

Alarm and temporary reset: in fig. 1, the alarm-reset lever 39 mounted on the main float 38 moves upward along the float. In fig. 6A, when the main float 38 rises and closes the main valve 22 (not shown in the figure for clarity), the upper end height of the alarm reset lever above the tank lid plate 33 rises h and provides a visual alarm. Pressing the tip of the alarm-reset lever 39 in turn pushes the main float 38 downwards and opens the main valve 22 and establishes the flow of water through it. However, when the tip of the alarm-reset lever 39 is released, the main float 38 is no longer caused to go down. However, when the tip of alarm-reset lever 39 is released, it no longer keeps main float 38 down and main valve 22 closed. This is a temporary mitigation method until the water leak is addressed.

Detailed description of another embodiment

Fig. 7 is a perspective view of a vertical displacement plate flush system 50 mounted in liquid flow communication over a toilet bowl 10.

Fig. 8 is an exploded view of the vertical shifter flushing system 50. The water supply to the irrigation system is established by a connector 51 connected to a normally open main valve 52. A normally open inlet valve 53 is connected to the lower end of the main valve 52. The inlet valve 53 discharges water into the water charging chamber 54, and the (water of the) water charging chamber 54 flows to the water storage chamber 55 through the open channel 56. During filling, the fill valve 53 discharges a small stream of water through a branch pipe (not shown) into the toilet bowl 10. Obviously, the water receiving chamber 55 and the water filling chamber 54 maintain the same water level during the water filling. The inlet valve float 57 is connected to the inlet valve 53 to open and close the inlet valve 53. The inlet valve float 57 moves up and down in the fill chamber 54 depending on the water level in the fill chamber 54. When the water in the charging chamber 54 reaches a set level, the inlet valve float 57 completely closes the inlet valve 53. Adjusting the connection between the inlet valve float 57 and the inlet valve 53 can achieve a desired fill level. The system is now ready for a flush operation. During a flush operation, water in the reservoir 55 is drained out through the outlet 61 into the toilet bowl 10.

The displacement plate 59 is oriented horizontally, with its edge matching the cross-section of the receiving chamber 55. These edges sweep the chamber walls of the water receiving chamber 55. The displacement plate 59 is moved up and down by a movable wire 60, one end of which is connected to the displacement plate 59 and the other end of which is connected to a flush handle 64. The flush handle is mounted in a scale guide channel 65 of the cover plate 63. The wires 60 are mounted on pulleys 68 for ease of operation.

When the drip chamber is filled to a set level, the system is ready for flushing. The downward movement of the displacement plate 59 is achieved by its weight or by an external force such as a spring (not shown) by moving the flush handle 64 along the graduated member 65, moving the displacement plate up and down through the electrical cord 60.

During the upward movement of the displacement plate, water above the plate overflows into the toilet bowl 10 by being directed through the drain 61. The vacuum created below the shifting plate 59 can be supplemented by water flow through the passage 56 into the water-filled chamber below the shifting plate 59. To make the displacement plate 59 move downwards faster, a check plate 67 is provided on the top surface, the check plate 67 being open during the downward movement and closed during the upward movement. Fig. 9 shows the check plate 67 fully closed during the forward movement, and fig. 10 shows the check plate 67 lifted to allow water to flow through the shifting plate 59. The tab below the check plate 67 prevents the tab from disengaging from the displacer.

Partial flushing: an advantage of this flush arrangement is that the flush handle 64 can be moved only as needed to achieve any amount of water above the drain plate.

Leakage prevention: a leak is defined as any uncontrolled flow of water into the receiving water container. Leaks may occur for a number of reasons, including inaccurate inlet level settings, leaks at the connections between the valve bodies, incomplete closing of the inlet valve, impeded movement of the inlet float, etc. In fig. 8, the drain chamber 66 is established below the main valve 52 and is separated from the fill chamber 54 by a check plate 67. A primary float 58 is attached to the primary valve 52, the primary float 58 moving up and down to respectively close or open the primary valve 52. Water flows into the drain chamber 66 from just above the drain chamber 66 and above the top edge of the check plate 67. Increasing the water level in the drain chamber 66 causes the main float 68 to rise and fully close the main valve 52. The system is shut down until there is no water, and once the leak is corrected, the water in the leak chamber can be drained and the main valve 52 can be opened for normal operation. In fig. 9, the water filling level of the water receiving container 190, the overflow level 191 of the check plate 67, and the drain level 192 above the water receiving chamber 55 are shown. It should be noted that the drainage requirement can only be achieved in the space above the displacement plate 59, which is isolated from the water-filled chamber 54. This is to ensure that flushing water does not enter the leakage chamber 66.

Alarm and temporary reset: in fig. 8, the alarm reset lever 69 attached to the main float 58 moves upward along the float. When the main float 58 rises and closes the main valve 52 (not shown in the figures for clarity), the upper end of the alarm reset lever 69 rises a height h above the cover 63 and provides a visual alarm similar to the device shown in fig. 6A, the only difference being the receiving container type. Depressing the tip of the alarm reset lever 69, in turn, pushes the main float 58 downward and opens the main valve 52, establishing water flow therethrough. However, when the tip of the alarm reset lever 69 is released, it no longer keeps the main float 58 down and the main valve 52 is closed. This arrangement is a temporary mitigation method until the leak is addressed.

Detailed description of another embodiment

Fig. 12 is a perspective view of a trough-shaped water-receiving receptacle flushing system 70 mounted in liquid flow communication over a toilet bowl 10.

Fig. 13 is an exploded view of the slotted receptacle flush system 70. The water supply to the irrigation system is established by a connector 71 connected to a main solenoid valve 72 which is normally open. A normally open water feed solenoid valve 73 is connected downstream of the main solenoid valve 72. The water inlet solenoid valve 73 discharges water into a reservoir chamber 74, and the reservoir chamber 74 flows to a gutter-type water receiving container 75 through an open passage 76. In fig. 14, the access port is provided with a non-return flap 293 which will prevent water from flowing from the slotted receptacle 75 into the reservoir 74. During a water-holding operation, the water inlet solenoid valve 73 discharges a small flow of water into the toilet bowl 10 through a branch pipe (not shown). The gutter-type receptacle 75 and the reservoir chamber 74 are maintained at the same level during the water storage operation. The water inlet solenoid valve switch 77 is connected to the water inlet solenoid valve 73 in such a manner as to open and close it.

The inlet solenoid float switch 77 moves upwardly to electrically close the circuit that energizes the solenoid of the inlet valve and moves downwardly to open the circuit and de-energize the solenoid in the reservoir 74 depending on the level of water in the reservoir 74.

When the water in the reservoir chamber 74 reaches a set level, the inlet solenoid float switch 77 energizes the inlet solenoid 73. The range of movement of the inlet valve switch can be adjusted to set the desired level of water storage.

When the tank reservoir 75 is filled to a set level, the system is ready for a flush operation. During a flushing operation, water from the trough-type water receiving container 75 is drained and directed into the toilet bowl 10 through the housing 81.

The displacement plate 79 used in this embodiment is a rectangular shape having four sides. One side is connected to a shaft that is supported across the slotted water receptacle 75, concentric with the cylindrical axis of the slot. The other 3 sides sweep the vertical and cylindrical walls of the trough. As the shifting plate 79 rotates on its axis, the water moves within the trough.

When the trough-type container stores water to a set water level, the system is ready for flushing. The flush handle 84 is connected to an axial end of the shift plate 79. The shifting plate 79 is also rotated (therewith) by rotating a flush handle 84 with a scale guide 85 suspended from the housing 81. One side of the water receiving container 75 of the groove type on the cylindrical surface determines a water discharge level of the groove, and water is discharged while rotating the displacement plate 79. The home position of the displacement plate 79 establishes the maximum amount of water and the displacement plate is returned to the home position by the torsion spring 82. One free end of the torsion spring 82 is attached to the slotted water receptacle 75 and the other end is attached to the flush handle 84. The torsion spring 82 is biased toward the home position. The displacement plates in the trough are constrained by two restraining bars 88 mounted on the trough-type receptacle.

In fig. 16, a movable check plate 90 is attached to an opening in the shifting plate 79 so that it can be covered. The check bar is inclined to close the opening during rotation of the shift plate 79 toward the discharge port of the slot, and closes the opening when inclined during reverse rotation. This can drain water, if any, remaining in the tank during the resetting movement.

Partial flushing: an advantage of this flushing arrangement is that any water volume in the tank can be flushed away by controlling the rotating displacement plate 79.

Leakage prevention: a leak is defined as any uncontrolled flow of water into a gutter-like receptacle. There are many reasons for leakage, including inaccurate intake level setting, leakage in connection between solenoid valves, incomplete closing of the intake solenoid valve, and obstruction of movement of the intake float. In fig. 13, the leak chamber 86 is located below the main solenoid valve 72, and is separated from the water storage chamber 74 by a partition plate 87. In fig. 15, a main float switch 78 is shown attached to the main solenoid valve 72, the main float switch 78 moving up and down, respectively closing or opening the circuit energizing the main solenoid valve 72. The leakage water flows into leakage chamber 86 from directly above leakage chamber 86 and above the top edge of partition plate 87. Increasing the water level in the leak chamber 86 raises the main float switch 78 and closes the circuit to energize the main valve 52. The water entering the system is shut off and the system is out of water. Once the leak is corrected, the leak chamber can be emptied and the main valve 52 can be opened for normal operation. In fig. 14, the level of the stored water in the trough receptacle 290, the overflow 291 on the check plate 67, and the drain 292 on the trough receptacle 75 are shown. It is noted that the drain level 292 is only reached in the space above the shifting plate 79 that is isolated from the reservoir 74. During a toilet flushing operation, the water level in the reservoir chamber 74 drops. This is to ensure that flushing water does not enter the leakage chamber 86.

When the main solenoid valve is activated, an alarm should be issued and reset:

when the main valve 72 is energized, a light bulb 103 is connected in parallel with the main valve solenoid light, thereby alerting the flush system to shut down. To override the closing of the system, a push button switch is depressed which opens a circuit that powers the main solenoid 72. The main valve solenoid is de-energized, opening the valve until the button is released.

The electronic control system is suitable for the embodiment.

The combination of the programmable electronic control system and the flush handle allows for intelligent and touchless operation of the system.

The electronic control system 101 includes a power supply, a computer control board, and its inputs include a touch pad, a microphone, a switch, etc. The control system is programmed to operate a controllable motor, such as a stepper motor, based on input to the control system. Feedback from the motor (such as load current, information input from position sensors, etc.) is also used to control the motor. The motor is bi-directional so that the shifting plate can rotate in either direction. The control system is mounted on the cover 83 and is connected to a solenoid valve, not shown for clarity. A drive belt 107 connects the shaft of the motor 106 and the shaft of the displacement plate 79. The tension on the drive belt 107 is optimized so that the flush handle 84 can be used for flushing when the electronic control system 101 is activated. The programmable controller may be programmed to respond to commands through the microphone 105 for voice activation or the touchpad 102 for touch control.

Detailed description of another embodiment

Fig. 18 is a perspective view of a rolling water receptacle flush system 20 placed in liquid flow connection over a toilet bowl 10.

Fig. 19 is an exploded view of the angled container flush system 120 shown in fig. 18. A rotating container support 121 that provides support for the tilting container 122 to roll smoothly on the axis. The flushing channel 123 is connected to the tilting vessel holder 121. The purpose of this passage is to provide a path for the toilet flush water dispensed from the tilting receptacle 122 into the bowl. Below the tilt reservoir 122 is a tilt reservoir flow control system 124 that controls the flow of water into the tilt reservoir 122. The flush handle 401 is attached to the angled container 122 for rolling it on its axis. The flush handle hovers over a graduated sticker 402 to guide the user in the degree of flushing.

The inclined receptacle bracket 121 shows a receptacle axis bracket 131 for supporting the inclined receptacle 122 and the inclined receptacle drip tray bracket 132, for supporting an inclined receptacle drip tray axis pin 146.

Filling operation of the inclined container 122

Fig. 20 is a perspective view of the tilt container flow control system 124 showing water flow through the system and being delivered to the tilt container 122 and flush channel 123 (not shown in this figure). Water traps in some types of toilets may require makeup water to maintain the water trapping function. Thus, water is added directly to the urinal during filling of the receptacle. The tilting vessel flow control system 124 is attached to the tilting vessel support 121 (not shown in the figures).

Fig. 21 is a perspective view of the tilting vessel flow control system 124. The water source connector 140 is connected to a normally open tilting vessel main valve 141 and also controls flow to a normally open tilting vessel water inlet valve 142. When the pin is depressed, the valve closes. These are typical diaphragm valves, water inlet valves that are commercially available and are operated by pins protruding from the valve. If desired, the tilt reservoir inlet pipe 143 delivers water to the tilt reservoir 122 and the flush channel 123, as shown in FIG. 20. The tilting container leakage tray 144 may be rotated under the valve body and is connected to the tilting container bracket 121 by the tilting container leakage tray shaft pin 146. Any leakage or spillage of water is collected by the inclined container drain tray 144.

FIG. 22 is a perspective view of the inclined reservoir water inlet valve 142 and the inclined reservoir 122. The inclined vessel 122, supported by the inclined vessel axis 122X, is inclined in a direction to close the inclined vessel water inlet valves 142 when filled with water. In this embodiment, the tilting vessel water inlet valves 142 are activated by the tilting vessel 122 through a mechanical linkage.

FIG. 23 is a perspective view showing the tilt reservoir 122 having been filled to a set amount and the tilt reservoir water inlet valves 142 closed to stop water flow to the tilt reservoir 122.

Fig. 33 is a side view of the tilted container 122, showing the container unfilled with water. The container is designed such that the center of gravity 320 is located between the tilted container axis 122X and the discharge side of the tilted container flush system 120. The design of the inclined container flush system 120 ensures the location of the center of gravity 320 by adapting means including properly positioning the inclined container axis 122X, adding springs and a large amount of things thereon.

As the tank is filled with more water, the center of gravity 320 is away from the discharge side of the inclined tank flush system 120 and passes through the inclined tank axis 122X. When the desired amount of water is reached, the tilt container 122 is swung into a position closing the tilt container water inlet valve 142, as shown in FIG. 23. The desired amount is defined as the maximum amount of water that can be drained from the container per flush operation. The water level 390 in FIG. 25 is designed to trigger a closed level of the tilting vessel inlet valve 142. If the water continues to flow for any reason, including being influenced by the tilted vessel axis 122X and not reaching the set position, the tilted vessel water inlet valve 142 is not fully closed and the water level continues to rise to 391 and out of the vessel through 125. The overflowing water is collected by the inclined receptacle drip tray 144 shown in fig. 26.

Flushing operation

Fig. 28 is a side view of the tilting vessel 122, where the flushing water is set to a water level 390 and the vessel is ready to tilt in the direction of the flushing channel 123.

FIG. 29 is a side view of the tilting vessel 122, where the tilting axis 122X on the vessel is manually tilted and a portion of the water in the vessel is drained into the flush channel 123.

FIG. 30 is a side view of the tilted container flushing system 120 with the tilted container 122 fully emptied into the flushing channel 123 and further rolling of the container restricted. During a flushing operation, all water released from the container is discharged only into the flush channel 123. The design of the system ensures that flushing water cannot overflow into the water leakage tray. Once a flush operation is initiated by tilting the vessel, the tilting vessel inlet valves 142 open and water is added to the vessel and a fill operation occurs as previously described.

Stopping water leakage:

fig. 26 is a front view showing the inclined container drain tray 144 without any water leakage. The tray center of gravity 320 is located between the inclined container drain tray axis pin 146 and the inclined container main valve 141 connection end. In this position, the tilting container main valve 141 remains open, allowing water from the water source connector 140 to pass through it.

Fig. 27 is a front view showing that the inclined container drip tray 144 has collected all of the water leaks, resulting in the center of gravity 320 moving between the inclined container drip tray axis pin 146 and the free end of the tray. This displacement has caused the tilting container drain tray 144 to tilt from its normal position and close the tilting container main valve 141 by a mechanical linkage. The amount of water collected in the inclined container leakage tray 144 that completely closes the inclined container main valve 141 is ensured by the proper balance of the inclined container leakage tray 144 and the force required for the mechanical connection between the inclined container leakage tray 144 and the inclined container main valve 141, which is achieved by means including weight adjustment across the inclined container leakage tray axle pins 146. An incorrect adjustment will prevent the tilting container main valve 141 from closing completely and water will spill out of the tilting container drain tray 144 and begin to collect in the stand. The flush system is considered leak-proof because the probability of simultaneous failure of the tilting vessel main valve 141 and the tilting vessel fill valve 142 is very low, if the system is properly designed and set up (failure probability) is very low. For simplicity, the means of balancing the tilt container 122 and the tilt container drip tray 144 are not shown, including the addition of large amounts of substances, springs, counterweights, etc. at strategic locations.

Leak alarm and reset

Fig. 26 shows that the tilting receptacle alarm reset lever 145 is rotatably connected to the tilting receptacle water leakage tray 144.

In fig. 27, the leak tray is tilted about leak tray axis pin 146 and tilted container alarm reset lever 145 is raised to height h. The raised portion acts as a visual alert to the user. The bracket means of the tilting container alarm reset lever 145 on the top thereof is not shown in the drawings.

To cover the closed and water-filled empty container of the inclined container main valve 141 for flushing, the tip of the inclined container alarm reset lever 145 is pressed and held down, which brings the tray to the pre-warning position, and the inclined container main valve 141 is opened. When the tank is filled to a set amount, the inclined tank alarm reset lever 145 is released and the inclined tank leakage water tray 144 returns to the alarm position and the inclined tank main valve 141 closes again. This process can be repeated until the source of the leak is identified and corrected unless the leak in the system does not spill over the leak tray during the water storage operation.
