Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a flushing toilet device, and particularly to a flushing toilet device that can be used hygienically anywhere as long as there is a power source, and that efficiently and effectively preserves water resources. This article relates to a toilet device that allows for

(Prior art) It is desirable that toilets can be used hygienically.
A typical example is the so-called flush toilet system, in which a large amount of washing water is used as transport water for the beam floor and as dilution water, and is transported to a distant treatment plant through the sewer system, where it is purified and then released. In addition, there are flush toilets that are combined with septic tanks that purify large amounts of dilution water, which is also a large amount of washing water, before discharging it. ) was used as cleaning water for the ball surface and odor sealing water, and the sewage from the beam floor was collected and stored in a waste tank, which was then pumped up with a vacuum truck or the like at the appropriate time and transported to a distant treatment plant for purification. There is a simple flush toilet with a reservoir that drains water afterwards.

There is also a flush toilet (Japanese Patent Publication No. 58-26999) that heats and evaporates the increased sewage in a simple flush toilet that refuses to do so and releases it into the atmosphere.

Also, there is a flush toilet (Special Publication Publication No. 56-162
66 Publication), a flush toilet that systematically collects and recirculates the flushing water that flows out at a time lag with the floor method (Japanese Patent Application Laid-open No. 51-52643), and the floor method. There is a flush toilet (Japanese Patent Publication No. 13342/1983) which performs cleaning and recovery of fruit and urine using water-insoluble cleaning liquids having different specific gravity and is reused.

(Problems to be Solved by the Invention) By the way, with conventional flush toilets, there is a problem in using flushes everywhere hygienically for the following reasons.

Honshui requires a large amount of water and sewage to transport the bed method far away, and if either of these is lacking, it cannot be used. Moreover, not only are there restrictions in terms of the scale of the equipment, but the treatment side in particular has serious problems in treating the large amount of sewage it produces. In other words, in addition to countermeasures against odor leakage, the discharged water has the characteristic odor of activated sludge containing microorganisms.
Furthermore, even if high-grade treatment is performed to achieve a removal rate of 85 to 95% of BOO, etc., the necessity of tertiary treatment has been considered in recent years from the perspective of water quality conservation. This is due to the fact that the amount of discharged water is so large that it exceeds the purifying ability of nature, and environmental destruction of water quality is progressing on a global scale.

Flush toilets combined with septic tanks also require a large amount of water to dilute the bed method, and cannot be used in places where water supply is not available. In addition, the equipment is limited to household use with a garden for installation, and it is impossible to make it smaller than that. Moreover, the discharged water produced in large quantities not only has the foul odor characteristic of activated sludge, but also causes river pollution. It is a major cause of

Even with a simple flush toilet, it is impossible to use it in places where there is no water supply, and on the other hand, it is a difficult task to draw water for flushing the toilet with a bucket.

Similarly, even the flush toilet described in Japanese Patent Publication No. 58-26999, which evaporates the increased sewage in a simple flush toilet, cannot be used in places where there is no water supply. Above all, in order to generate a large amount of evaporated air, the air is heated to high temperatures and the even more intense odor is released into the atmosphere.
There is a fatal problem in that the environment is severely destroyed and it cannot be put to practical use.

Regarding this odor problem, attempts have been made to prevent the odor from leaking by forming a trap in the middle of the exhaust pipe of the evaporated air, but in reality, each time the evaporating air pressure of the strong odor rises to a certain pressure, the trap passes through the trap. The odor problem remains virtually unsolved.

On the other hand, flush toilets that use flush water repeatedly have the following problems, although they do not require a water supply.

For example, in the flush toilet described in Japanese Patent Publication No. 56-16266, sewage is permeated into the soil through capillary tubes.
In order to obtain washing water by purifying it with microorganisms, the scale of the equipment inevitably becomes large, and not only does it require more installation space than a septic tank, but its processing capacity is affected by climate conditions, and above all, it is still difficult to manage administratively. The current situation is that it cannot be implemented as approval from the agency has not been obtained.

Also, JP-A-51-52643 and JP-A-51-52643
In the flushing toilet described in Publication No. 13342, the flushing water gradually becomes dirty in proportion to the number of flushes, and the toilet must either endure the smelly dirt or dispose of the flushing water along with the filth as soon as possible. However, there is a problem in that it is difficult to use it hygienically. Moreover, the size of the return urine tank and the number of times it is pumped out remain the same as before, and on the processing side, there are various problems caused by diluting and purifying the collected urine, the absolute amount of which does not change, with a large mouth of water. In other words, odor control,
There are problems with environmental destruction due to the odor peculiar to activated sludge and water quality caused by large volumes of discharged water.

In this way, all types of flush toilets do not allow for hygienic flushing and efficient and effective cleaning of water resources in all places, but the goal of universal flushing is the direction of the floor law treatment administration. This has led to the emergence of effective flush toilet devices that bring good results to the treatment side.

The present invention has been made in view of such demands, and can be used hygienically for washing with water as long as a power supply is available, and moreover, it reduces the absolute amount of treatment on the treatment side, making water resources efficient and effective. The purpose of the present invention is to provide a flush toilet device that can maintain cleanliness.

(Means for Solving the Problems) The means taken by the present invention to achieve the above-mentioned objects is to connect the flush toilet bowl and the heated filth chamber, and to heat the heated filth chamber and the low-temperature liquefaction chamber. A gas circulation system path consisting of an outgoing ventilation path from the waste room to the low temperature liquefaction room and a return path from the low temperature liquefaction room to the heated waste room is connected to the sanitary water storage section in the low temperature liquefaction room and the flush toilet via a water supply system path. It is characterized by being connected directly or through a wash water tank.

More specifically, only water is collected from wastewater through transpiration and condensation through circulation to obtain sanitary water with components close to pure water, and this sanitary water is recycled as cleaning water and reused repeatedly. Regardless of the concentration characteristics of the raw sewage, it is possible to produce sanitary water that is higher than high-grade treatment (q), and to completely seal the gas passage that transports and circulates the water in the sewage, eliminating odors from the atmosphere unlike conventional transpiration treatment. Process it without releasing it.

In addition, the temperature of the heating room can be changed as necessary, for example, for vehicles,
In cases such as aircraft, where washing capacity is prioritized over heating energy consumption, high energy is used to increase the temperature difference between the heating chamber and the liquefaction chamber, and sanitary water is used as washing water. For household use, by creating an appropriate temperature difference with low energy consumption, the appropriate amount of washing water can be obtained according to the number of users, and the temperature of the heating room can be maintained at an anaerobic level throughout the year. By optimizing the growth conditions for microorganisms, it is possible to decompose all the solid waste in the bed method into water and gas, leaving almost no sludge.

(Function) The gas circulates between the heated sewage chamber and the low-temperature liquefaction chamber via the circulation system path, and in the heated sewage chamber, it enters the low-temperature liquefaction chamber from the ventilation path, containing the water that has evaporated from the wastewater, and enters the same. After the moisture is condensed in the air and liquefied and recovered to become dry air, it enters the heated waste room through the ventilation return path, and this process is repeated from the heated waste room side to the low-temperature liquefaction room side. The sanitary water is purified and recovered, and from the low-temperature liquefaction chamber, the sanitary water is circulated as washing water through the water supply line to the flush toilet bowl and then to the heated filth chamber.

As a result, cleaning water, which is sanitary water, can be generated and recovered from waste water using the circulating gas and used for continuous washing, and the surplus sanitary water is discharged, etc., and then pumped out and treated in the heated waste room. The amount of sludge can be reduced by one hour to the point where it only needs to be pumped out on a yearly basis.

(Practical example) An example of the implementation of the present invention will be described in detail below with reference to the drawings.

FIG. 1 schematically shows the flush toilet device of the present invention.

Flush toilet device (A> is a flush toilet (1), a heated waste room (
2), low temperature liquefaction chamber (3), circulation system path (4), water supply system path (
5).

The flushing toilet (1) has various configurations that require about 200 cc to 124 m of flushing water, and the water outlet (6) is connected to the water supply line (5) directly or through the flushing water tank (7).
It communicates with the heated filth room (2) through the defecation pipe (8), so that water for bed filling and washing flows into the heated filth room (2) through the defecation pipe (8). .

The heated waste room (2) is preferably formed by a flat tank (9) with a large evaporation area of wastewater, and the room is heated with low energy such as a surface heating heater automatically controlled by a temperature sensor etc. The heating element (10) keeps the temperature around 40°C.
The temperature is kept at ±5 to 10 degrees Celsius, and mesophilic bacteria actively live in the anaerobic room, which promotes the decomposition of waste materials and facilitates the smooth liquefaction and gasification of relrose-based substances. It is designed so that it can be used. In addition, the level of sewage in the room is monitored by a water level sensor, etc., and the pump (11) of the circulation system path (4) is controlled to keep it at a constant level.

The temperature of the low-temperature liquefaction chamber (3) in the tank (12) should preferably be about 20°C different from that of the heated sewage chamber (2), and it should be installed underground according to the required liquefaction capacity. This low-temperature liquefaction chamber (3) is optionally equipped with a cooling element (13) such as a cooling system using temperature, a semiconductor cooling system, or a general-purpose cooling system, and removes sanitary moisture from the gas circulating in the circulation path (4). It is liquefied and removed, stored in a tank (12), and recovered.The low-temperature liquefaction chamber (3) is equipped with an overflow (14), and the purified and recovered surplus sanitary water is appropriately discharged to the outside of the tank or evaporated. That's what I do.

The circulation system path (4) runs from the heated waste room (2) to the low temperature liquefaction room (3).
), and a ventilation return path (16) that leads from the low-temperature liquefaction chamber (3) to the heated waste chamber (2), and the gas is heated by a pump (11) in the middle of the yarn path (4). Filth room (
2) through the ventilation outgoing path (15), the low-temperature liquefaction chamber (3), and the ventilation return path (16) to the heated waste room (2), which is even more effective than natural convection without using the pump (11). In order to ensure efficient collection processing, and to allow the gas to circulate with extremely low oxygen content without any interaction with the outside air, the anaerobic state within the heated waste room (2) is not impaired, and the bed method using anaerobic bacteria is used. Anaerobic decomposition of wastewater is actively carried out. Note that even if the pump (11) is not installed, the temperature difference between the heated filth chamber (2) and the low-temperature liquefaction chamber (3) causes natural convection of gas, and the sanitary water recovery process is performed.

The water supply line (5) communicates between the water outlet (6) of the flush toilet (1) and the sanitary water storage section (3a) in the low temperature liquefaction room (3) either directly or via the flush water tank (7). The sanitary water in the low-temperature liquefaction chamber (3) can be supplied to the flush toilet bowl (1) as flush water using a pump (17) in the middle of the optical path.

In addition, an air supply line (18
). This air supply line (18) reaches into the wastewater, and the gas is blown into the wastewater, and the air supply pressure stirs and mixes the bed method wastewater to prevent scum from accumulating on the surface of the wastewater, which would impede anaerobic decomposition and evaporation. At the same time, all organic matter is decomposed and gasified in about three months.

If the tank (9) in the heated sewage room (2) is for household use, it is best to remove the sludge from the outlet (19) every three years or so before the salt concentration becomes too high. It seems so.

In addition, it is desirable to cover the heated waste room (2) and the low-temperature liquefaction room (3) with a heat insulator (20) to keep them warm, so that they can be collected and processed in a fixed amount regardless of climate conditions. .

The quality of the sanitary water supplied to the flush toilet (1) via the water supply line (5) is as shown in the following table.

■, Effluent water standards (Kama 0 City) Next, examples will be described for each application.

Figure 2 shows an example for home use.

The flush toilet device (A) has a spiral gas ventilation path (21) in the low-temperature liquefaction chamber (3), and pumps (17) pumps sanitary water in the same room (3) into the ventilation path (21). The water is pumped up and showered in the shower (22) to increase its ability to congeal and liquefy.

As a result, the bed and washing water that flowed from the flush toilet (1) through the defecation pipe (8) into the heated waste room (2) are anaerobically decomposed in the heated waste room (2) and evaporated from the sewage surface. The evaporated gas is absorbed by the gas circulating in the circulation system path (4) and sent to the low temperature liquefaction chamber (3).
3), the evaporated water is condensed and liquefied and recovered from the air passage (21) through the water inlet (23).

Then, the sanitary water is pumped (17) into the cleaning water tank (
7), flows out from the same tank (7) as flush water into the flush toilet bowl (1), and after cleaning the ball surface, flows back into the heated filth chamber (2).

Therefore, it can be used for general household use in areas without sewage systems, without requiring a washing water supply system, a transport or water transportation means for removing the beam floor, and a treatment facility for purification. In addition, the cleaning water can be collected and used comfortably without the problem of odor caused by the cleaning water itself. In particular, the amount of water used to flush the flush toilet (1) is 500cc.
By making it a simple type that requires less than a heating element (
10) and the cooling element (13) can have low energy consumption, and can be used economically advantageously.

FIG. 3 illustrates a closed system flush toilet device.

This flush toilet device (A) is a flush toilet bowl (1).

Heated waste room (2), low temperature liquefaction room (3), circulation system path (4)
, the water supply system path (5) is made into a unit, and a solenoid valve (24) is arranged in the middle of the water supply system path (5) to open the water outlet (6).
) to control water supply. Further, the flush toilet bowl (1) is of a simple flush type with a flushing water volume of about 500 cc or less.

As a result, the bed and washing water flow from the flush toilet (1) through the defecation pipe (8) into the heated filth chamber (2), and the evaporated gas evaporated from the sewage surface in the heated filth chamber (2). is absorbed by the gas circulating in the circulation system path (4) and sent to the low-temperature liquefaction chamber (3), where the evaporated water is condensed and liquefied, and then passed from the ventilation path (21) to the water inlet. (23) and is collected. Then, the sanitary water passes through the solenoid valve (24) which is opened according to an instruction, flows out from the spout (6) onto the ball surface, cleans the ball surface, and then flows back into the heated waste chamber (2).

Therefore, there is no need for a washing water supply system, transportation or water transportation means for removing the bed, and treatment equipment for purification, and the amount of washing water per wash can be reduced, making the setting easier. If the number of users is the same, the volume of the heated waste room (2) and low-temperature liquefaction room (3) can be reduced to promote the downsizing of the entire device, which can be used not only for general households but also for ships, aircraft, trains, and buses. It can be used as a closed toilet with its own water supply and collection processing capabilities, and can be used for various transportation vehicles such as mobile toilets, as well as indoor portable toilets. It can be used comfortably and widely without any harmful effects.

Although not shown, there is also a mode in which the low-temperature liquefaction chamber (3) is formed, for example, in a tank (7) installed at the rear of the upper edge of the flush toilet (1). If the cleaning device is of a simple washing type that requires less than about 500 cc of washing water per wash, it is possible to further downsize the entire device.

For the simple flush type flush toilet (1) (the flush spout (7) was developed by the applicant in 1987-3855).
The water discharge nozzle No. 2 is appropriate, and the toilet bowl (25) of Utility Model Publication No. 56-9749 is also effective.

(Effect of the invention) Therefore, the present invention has the following advantages.

■ Gas circulating along the circulation path between the heated sewage chamber and the low-temperature liquefaction chamber transports the evaporated moisture in the heated sewage chamber to the low-temperature liquefaction chamber, where the moisture is condensed and liquefied before being discharged.
