Description

Toilet bowl cleaning system using compressed air {TOILET FLUSHING SYSTEM USING COMPRESSED AIR}

The present invention relates to a toilet cleaning system, and more particularly to a toilet cleaning system using compressed air.

Along with water shortages, too many wastes and wastes are generated worldwide.

At present, the world population is about 6 billion, and in many countries such as Brazil, the urban population accounts for 80% of the total population. In other words, people are gathered into the upright structure of the city, a certain area is covered with asphalt and overpass for the communication of vehicles, and the clean river basin where human history began, is being transformed into open sewage.

The average daily human waste discharge is about 2 liters of urine and about 700 grams of feces.

Urine is discharged several times a day, and solid dirt, or feces, is discharged once or twice a day. Most of these waste discharges are flushed down the toilet, which consists of a powerful jet of water at high speed and a specific type of vortex system with three purposes:

1. For the purpose of removing dirt, liquids or solids, including toilet paper, from the place of attachment;

2. The purpose of the formation of water streams in the public sewer pipes to direct the dirt to sewage treatment plants or natural sources such as rivers and seas.

3. To clean the toilet by removing dirt that may be stuck to the toilet wall.

About 20 years ago, there were two major existing systems as flush products.

1. In the oldest structure, approximately 30 liters of box are located about 2 meters higher than the toilet, from which water is discharged at high speed by siphon through a larger diameter tube.

2. In an upright structure, certain valves are connected to larger diameter and higher pressure pipelines, which remain open for varying times upon pressurization, such that a sufficient amount of water discharges the stool and any material adheres. Have the sidewalls of the toilet bowl clean as much as possible.

The first system worked economically satisfactorily as the siphon drained the contents from the reservoir (reservoir box) within seconds in operation. However, because the diameter of the connection with the domestic water supply system is small and the difference in water level with the domestic water storage box is small, it takes several minutes to refill the washing water box, and due to the siphon system, the water level of the washing water box or the washing water box is constant. It did not work until it was reached.

In the second system, according to the investigation of the toilet drainer, the valve can be deliberately pressurized for a long time and kept open in the pressurized state, so that a large amount of unnecessary water is removed when the user performs the cleaning operation with mischief. Resulted in consumption.

In recent years, technical standards for residential, commercial and industrial installations have saved water from toilet flushing water, and Brazil has limited it to 6 liters per cycle. This provision has been technically achieved and its construction shows that the wash water reservoir is arranged in parallel on the upper back of the toilet, is operated by a siphon system of pipes of limited diameter, large diameter, and generates considerable water flow for a while. You can. All of these technical configurations are made by new shaped toilet and wash water ducts which allow the wash water flow to be formed and operated in a vortex.

According to the technical configuration in which the reservoir is filled via a small diameter connection to the internal water supply system, it takes considerable time to refill the reservoir, which does not generate rinsing water continuously, which is a deterrent to the removal of dirt. do.

One important point to note is that, unlike industrial applications where water with different purity levels can be used, water used for domestic toilet flushing is precisely treated for its use, making it suitable for drinking water. .

Therefore, recent techniques for domestic toilet rinsing water are aimed at improving overall performance along with the need for water saving, and in order to be able to generate traction with a small amount of water even in the case of the selected geometry. It has a technical configuration that depends on gravity.

However, three very complex technical requirements were imposed, which are very specific as technologies for airplanes, ships and submarines.

These requirements are quite different in that large external pressures, such as in ships and submarines, are not applied to the toilet, and that airplanes with pressurized cabins fly at altitudes with minimal external pressure. Pressure control at

In airplanes where the cost of flight is proportional to the weight of the cargo, the consumption of the wash water should be minimized. This is a problem for intercontinental planes that fly hundreds of passengers with food and all sorts of beverages for more than 12 hours. It becomes a very serious problem.

Therefore, historically, the technical development of toilet rinsing water has been very sophisticated, but many technical solutions developed for some facilities have not been available in the market, because these solutions are very expensive and very demanding. In addition, it requires more maintenance work than conventional systems. One evolutionary method for the art has already been found, which is water saving.

Applicants have reviewed innovative proposals for the field of technology and found that based on patent literature, more than 600 related documents have been found, but as described herein, it is possible to very simply save a large amount of water. We have not found at least one suggestion for technological progress.

Two recently used methods and means are to apply a gravitational effect to a significant volume of water or to create a low pressure in a sewer pipe, which is known as "vacuum pressure", where local atmospheric pressure is a low pressure in water and dirt. Pressure is applied in the duct direction.

A third, less frequently used method is to pressurize water to release dirt from the toilet.

All of these methods and hundreds of devices presented in common have the commonality that they operate with the toilet lid open.

According to the first technical aspect with the considerable advancement presented in the present invention, the toilet is operated with the toilet lid sealed by a rubber ring or the like and releases the dirt and the hydroseal contaminated by the dirt. When pressurized, the inside of the toilet is pressurized to a relatively low pressure by compressed air, ie the toilet uses a lot of compressed air to replace only a significant volume of water subjected to gravity.

Secondly, the present invention describes for the first time in this specification a computerized technology that enables the preservation of water used to remove human waste, and the object of the present invention is to provide a mechanism that is operated periodically and automatically operated by "PLC". To provide.

Third, by utilizing pressurization techniques to remove dirt, the present invention enables the removal of large amounts of dirt without the production of residues while saving water, an increasingly rare and increasingly expensive resource on a daily basis.

Fourth, the present invention can significantly reduce the amount of water required to remove dirt from the toilet by using the above-described mechanism, and even if the amount of water is less than 2 liters in each use, a large volume of the object can be Can be released. Two liters of water is the least consumed compared to the most economically recommended amount.

Fifthly, the object of the present invention includes a "automatic cleaning" function, which allows to save required cleaning work and chemical cleaning products and to keep the entire system clean and odor free at all times.

FIG. 1 is a schematic diagram schematically illustrating the operation of a toilet cleaning system using compressed air as a whole.

FIG. 2 is a schematic illustration of an operating circuit (operational diagram) and devices thereof in order to be able to use as a reference figure the detailed description of a "toilet toilet cleaning system using compressed air".

1 is a schematic diagram schematically showing the operation of the toilet cleaning system 1 using compressed air as a whole, and includes a toilet 21 having a hydroseal 22 and a siphon sewer ( 23 and a toilet lid 18 with a latch, and also shows a compressed air tank 24, a pressurized water tank 25, an air compressor 27 and a PLC 16. have.

The toilet cleaning system 1 using compressed air operates as follows. According to FIG. 1, the toilet lid 18 is closed after use and held in position by the latch 26. When the user activates the command button 20, the PLC 16 operates the necessary devices so that the compressed air introduced by the air compressor 27 has a toilet 21 under a pressure of 25 psi formed in the compressed air tank 24. It is rapidly discharged to the inside, creating an air stroke and a pressure of approximately 4 psi inside the toilet 21, which causes the water constituting the hydroseal 22 in which dirt is accumulated to be discharged by an effective stroke. Compressed air, together with dirt and water, is forced down to the siphon sewer 23 to return the internal pressure of the toilet 21 equal to the local atmospheric pressure. The operation of the automatic devices is maintained by the appropriately programmed PLC 16, which releases a portion of the contents of the pressurized water tank 25 for the " automatic cleaning " A tip is used to clean the toilet 21 wall with pressurized water so that water contaminated by dirt stuck to the toilet 21 wall replaces the hydroseal 22. The next operating step by the PLC 16 is to release part of the contents of the compressed air tank 24 to create a new stroke of compressed air, which is composed of dirt and water cleaned from the wall by the previous automatic operating step. The hydroseal 22 is removed again and the compressed air is forced through the siphon sewer 23 under low pressure to return the internal pressure of the toilet 21 equal to the local atmospheric pressure.

The next operating step, commanded by the PLC 16, replaces the hydroseal 22 with a new amount of water from the pressurized water tank 25 and the toilet lid through a latch 26 fixing mechanism (not shown in FIG. 1). (18) releasing, leaving the entire system free for new use, where the air compressor 27 will replace the pressure involved in the process and the water from the water system contained in the pressurized water tank 25 Because it works.

According to the schematic operating description of FIG. 1, which shows the automatic operation state which can be executed by anyone pressing one button, unnecessary devices are omitted to understand how the toilet cleaning system of the present invention is operated. The concept of "toilet toilet cleaning system (1) used" can be clearly understood, and this system is operated by PLC to reduce the amount of cleaning work required and the water and chemical cleaning products when removing dirt from the toilet. It is a completely new and automated system that can be operated by pressing a single button with the aid of compressed air to replace a significant amount of gravity under the removal of dirt and contaminated water with compressed air, draining and replacing the toilet's hydroseals. It is a system that performs a cycle.

FIG. 2 is a schematic illustration of an operating circuit (operational diagram) and devices thereof in order to be able to use as a reference figure the detailed description of a "toilet toilet cleaning system using compressed air". 2 shows an automatic operating state of the toilet cleaning system of the present invention. In order for this toilet cleaning system to operate, the toilet cleaning system is connected to the domestic water pipe system 1A to supply water, the air is supplied through the air inlet 27A, and the toilet cleaning system is connected to the household wiring system 3A. To supply electrical energy.

The water supply system has been proposed in consideration of a plan for providing a water supply and drainage component used in recent years. That is, the water supply device requires a water supply having the same technical specifications and characteristics as a conventional toilet combined with a flush water supply. According to the proposed scheme, the compressor 27 is manufactured as a compressed air supply device to fill the tank 24 with compressed air. Finally, a power supply of 127 V or 220 V has been proposed for electrical energy requirements.

A description of a typical basic operating cycle is sufficient to fully understand the operating relationship of the toilet cleaning system of the present invention.

The devices needed to make the system work include:

-Compressed air tank (24) with an internal pressure of 25 psi

Filled pressurized water tank (25)

-Compatible power grid connected to the electrical transmission board (3);

Programmable and powered PLCs (16)

-Hermetic lid (18)

Locked solenoid latch 17 (electrical circuit does not tension the fixed solenoid latch)

When the command button 20 is pressed, the PLC 16 immediately activates the solenoid valve 13 to open for a few seconds, causing compressed air to be forced from the compressed air tank 24 into the toilet 21 to pressurize the toilet. do. By this operation, all water and substances contained in the hydroseal 22 are released. The expected pressure of the chamber inside the toilet 21 at the time of supply of compressed air is measured by the pressure gauge 15 as 4 psi. If the pressure in the sanitary basin chamber exceeds 5 psi, the pressure gauge 14 sends a signal to the PLC 16 to keep the solenoid valve 13 and solenoid latch 17 closed. .

When the pressure in the compressed air tank 24 is depressurized, the pressure gauge 10 sends a signal to the PLC 16 to immediately activate the air compressor 27 to allow the air to be replenished in the compressed air tank first. . When the expected pressure (25 psi) of the compressed air tank 24 is reached, the pressure gauge 10 sends a new signal to the PLC 16 indicating that the tank is fully filled, where the PLC 16 receives an air compressor 27 At the same time, the solenoid valve 6 and the solenoid valve 11 are opened, the cleaning process of the inner wall of the toilet 21 is started through the tip 19, and the hydroseal 22 is replaced. .

When the internal pressure of the compressed air tank 24 is depressurized again because air is needed for wall cleaning device and hydroseal replacement, the pressure gauge 10 sends a signal to the PLC 16 and immediately the air compressor 27 Secondly, air replenishment in the compressed air tank 24 is effected by instructing it to operate. As with the first refill process in the compressed air tank 24, once the expected pressure (25 psi) of the compressed air tank is reached, the pressure gauge 10 sends a signal to the PLC 16 indicating that the tank is fully filled. In this case, the PLC stops the operation of the air compressor 27.

When the cleaning process of the wall of the toilet 21 and the replacement process of the hydroseal 22 are completed, the solenoid valve 6 and the solenoid valve 11 are closed simultaneously by the PLC 16 command.

At this stage, the whole system can be fully returned to function to release the hydroseal and its contents a second time, which is done by sequential PLC 16 instructions.

This second release process is performed automatically by the PLC 16, not by manual operation of the user.

When the command signal is transmitted by the PLC 16, the solenoid valve 13 is opened, and the compressed air stored in the compressed air tank 24 is pumped into the toilet 21 to apply pressure to the toilet. By this operation, all the water and the substances which were discharged from the wall cleaning process and included in the hydroseal 22 are released. In this operation the expected pressure in the toilet 21 should also be 4 psi, which is measured by the pressure gauge 15. If this pressure is greater than 5 psi, the pressure gauge 14 sends a signal to the PLC 16 to close the solenoid valve 13 and keep the solenoid latch 17 locked. When the pressure in the compressed air tank 24 is depressurized, the pressure gauge 10 sends a signal to the PLC 16 to immediately operate the air compressor 27 a third time so that the third air refill in the compressed air tank To be done. When the expected pressure (25 psi) of the compressed air tank is reached, the pressure gauge 10 sends a new signal to the PLC 16 indicating that the tank is fully filled, which causes the air compressor 27 to stop operating. It continues until the end of the next command operation, that is, the water replenishment operation in the pressurized water tank 25.

The PLC has a program with operational continuity and the first replenishment of water in the pressurized water tank 25 is initiated by simultaneous opening of the solenoid valve 11 and solenoid valve 12. The function of the solenoid valve 12 is to enable replenishment of the water in the pressurized water tank 25 so that residual compressed air can pass when the level of such pressurized water tank rises.

When the maximum level of the pressurized water tank 25 is reached, the level control key 5 sends a signal to the PLC 16 to close the solenoid valve 11 and the solenoid valve 12 simultaneously, The automatic operation cycle of the used toilet cleaning system 1 is continued. When the compressed air tank 24 is completely filled with compressed air and the pressurized water tank 25 is replenished, the PLC 16 simultaneously opens the solenoid valve 6 and the solenoid valve 11 and the toilet by the tip 19. (21) The start of the second cleaning process of the inner wall and the replacement of the hydroseal 22 is ordered. When air is needed again for the second wall cleaning and hydroseal replacement cycle, when the internal pressure of the compressed air tank 24 is depressurized again, the pressure gauge 10 sends a signal to the PLC 16 to immediately activate the air compressor ( By actuating 27, the fourth and final air replenishment in the compressed air tank 24 is initiated.

When the expected pressure (25 psi) in the compressed air tank 24 is reached, the pressure gauge 10 sends a signal to the PLC 16 indicating that the tank is fully filled, where the PLC stops operating the air compressor 27. Stop it.

When the wall cleaning process and the hydroseal 22 replacement process are completed, the solenoid valve 6 and the solenoid valve 11 are simultaneously closed by the command from the PLC 16.

Finally, at the end of the operating basic cycle, a second replenishment of the water in the pressurized water tank 25 is initiated by simultaneous opening of the solenoid valve 11 and the solenoid valve 12, which process is initiated by the PLC 16. Is done by. As with the first replenishment process, when the maximum water level in the pressurized water tank 25 is reached, the level control key 5 sends a signal to the PLC 16 to simultaneously close the solenoid valve 11 and the solenoid valve 12. Let's do it. This completes the basic operation cycle. At this stage, the toilet cleaning system may perform a new operating cycle when the user presses the command button 20.
