Particularly, in a method using a drug, a solid-liquid separation mechanism is provided for separating stool excreted in the toilet and urine and toilet flush water at an appropriate ratio, and the stool is guided to a stool treatment tank and fermented by microorganisms. In the case of a toilet system that is disassembled and the urine and toilet flush water is led to a recycling tank and the toilet is washed using the urine and toilet flush water in the recycle tank, since there is a solid-liquid separation mechanism, Urine and toilet flush water is to be put in the recycling tank,
Some urine and toilet flush water will also enter the stool processing tank. If a chemical is put in the toilet flushing water, microorganisms in the stool processing tank are killed, which has a disadvantage that fermentation decomposition of stool is adversely affected.

[0004] In the case of microorganisms, there is an effect of eliminating urine, but it is expensive, the life of the microorganism itself is short, and there is almost no long-term maintenance-free use. .

[0005] In particular, the water-circulating toilet system that decomposes excreta using microorganisms is provided with a mechanism for separating stool, urine, and toilet flushing water in the toilet, and the stool is guided to a stool treatment tank that is fermented and decomposed by microorganisms. The urine and toilet flush water is led to a recycling tank, and the excrement is decomposed by using microorganisms that wash the toilet using the urine and toilet flush water in the recycle tank.

In this toilet system, a tub filled with water is provided in advance, and urine is guided to the tub and deodorized and decomposed by microorganisms contained therein to clean the urine, and the treated water is used as washing water for toilet bowls. It is used for recycling.

In this type of toilet system, maintenance is performed only once every three months or six months. In such a toilet system, in the conventional treatment using microorganisms that are troublesome to manage such that microorganisms must be added every day or every few days, neglecting such treatments will result in sufficient urine consumption. Can not smell,
There is a drawback in that an unpleasant odor such as the ammonia odor of urine cannot be sufficiently eliminated.

Further, the microorganisms for decomposing urine used therein are troublesome in various handling conditions such as temperature and are expensive.

[0009] The object of the present invention is to eliminate the use of drugs
It is possible to deodorize urine without introducing it every few days as with conventional microorganisms and without complicated management,
Furthermore, toilet bowls and other piping passages can be cleaned using organic organisms similar to microorganisms capable of decomposing organic substances, and the organic organisms are extremely easy to self-reproduce easily even in maintenance-free operation. It is an object of the present invention to provide a method of deodorizing urine which is inexpensive in a toilet system or the like, and a toilet system using the method.

[0010]

SUMMARY OF THE INVENTION The object of the present invention is as follows.
Chlorella bacteria may be given to the place excreted in the urinal or having urine such as a urine storage tank by mixing or spraying the chlorella bacteria, or a solid substance of the chlorella bacteria may be inserted, and the chlorella bacteria may be used to remove the urine. This can be achieved by providing a method for deodorizing urine in a toilet or the like in which ammonia is deodorized.

Another object is to provide a solid-liquid separation mechanism for separating stool excreted in the toilet and urine and toilet flush water at an appropriate ratio. The stool is guided to a stool treatment tank and fermented and decomposed by microorganisms. And toilet flush water is led to a recycling tank, the toilet system in which the toilet is washed using the urine and toilet flush water in the recycling tank,
This can be achieved by providing a toilet system in which chlorella bacteria are mixed in the recycle tank so as to eliminate ammonia in urine.

(Operation) The operation will be described with reference to FIGS. When a person enters the bathroom, the motion sensor 4
(See FIG. 2) senses a person. The signal is motion sensor 4
The washing water pump (washing water P) 22 operates according to a signal from the control panel (control circuit) 6, and the recycling tank 5 (in FIG. 2, mainly the treated water storage tank 9 in the recycling tank 5) is operated.

When a person applies excrement, in this case, it is assumed that both the stool 2 and the urine 3 are excreted.
5, the urine 3 and the toilet flush water 4 are recycled through the passage 14 because the urine 3 and the urine 3 and the toilet flush water 4 have a structure having a mechanism for separating the urine 3 and the urine flush water 4. It is led to the tank 5. The details of the recycling tank 5 will be described later.

The stool 2 (the stool in this case also includes solid toilet paper, etc .; the same applies hereinafter) is provided with a stool sliding plate below the hole 13 constituting the solid-liquid separator 55 provided at the lower part of the toilet 1. Fall in the direction controlled by 25. The stool 2 at this position is guided to the stool processing tank 7 via the passages 26 and 29 by the compressed air sent from the air compressor 23, and the drop port formed in the passage 29 at the upper position of the stool processing tank 7. It falls into the stool processing tank 7 installed on the floor 88 or the ground via 31.

Since the odor remaining in the passage 29 is sequentially supplied with air from the e-compressor 23, the odor is guided to the deodorization tower 38 through the passage 37 and deodorized by the deodorant 39. After that, the passage 41 is further provided by the exhaust fan 40.
Is discharged to the outside.

The stool processing tank 7 contains microorganisms 1 for stool decomposition.
5 (generally, microorganisms are supported on a moisture regulating material such as sawdust). Therefore, since such microorganisms 15 are used here, the stool 2 is decomposed into carbon dioxide and water (steam) and disappears. When the microorganism 15 is intended for compost, the stool 2 produces compost.

The stool-decomposing microorganisms 15 in the stool processing tank 7 into which the stool 2 has been put are moved by the stirring blades 32 arranged in the stool processing tank 7 three times a day based on a signal from the control panel 6.
The motor 33 is driven so as to stir about five times.

Assuming that the microorganism 15 uses sterilization,

Conventionally, microorganisms are added to remove the smell of ammonia (including other contaminants). But,
In the present invention, the chlorella bacterium 24 is mixed into the treated water 12 in order to measure the deodorization / decomposition / pile bacteria of the ammonia.

The chlorella bacterium 24 is cultured and propagated by a growth light source, for example, a fluorescent lamp 43, placed in a transparent pipe 42. By the lighting of the fluorescent lamp 43,
Chlorella bacteria 24 can grow without exposure to external sunlight.

In the recycle tank 5, a throw-in type heater 27 is provided to keep the temperature of the treated water 12 constant or appropriate, and at the same time, a temperature sensor 28 for detecting the temperature of the treated water 12 is provided. The operation of the heater 27 is controlled by the temperature controller 44 based on the signal of the temperature sensor 28 to maintain the treated water 12 in the recycle tank 5 at an appropriate temperature.

A turbidity meter 45 is provided in the recycle tank 5, and the chlorella bacteria 2 in the recycle tank 5
4 can be detected. Chlorella 24
Has a different growth rate depending on the temperature. Therefore, based on the signals from the temperature sensor 28 and the turbidimeter 45, the temperature of the heater 27 and the illuminance of the fluorescent lamp 43 are maintained at appropriate values, and the concentration of the chlorella bacteria 24 is maintained at an optimum value. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an explanatory view of a water-circulating toilet system for decomposing excreta using microorganisms according to one embodiment. FIG. 2 shows a stool 2, a urine 3, and a toilet flushing water 4. FIG. 3 is an explanatory diagram of an embodiment of the toilet 1 provided with a separating mechanism, FIG. 3 is an explanatory diagram showing an electric flow, and FIG. 4 is an explanatory diagram of a turbidimeter 45 as an example. Hereinafter, a method of deodorizing urine in a toilet and a water circulation type toilet system for decomposing excreta using microorganisms using the method will be described with reference to FIGS. 1 to 4.

The toilet 1 is installed in a private room (not shown) of the toilet system. In this toilet 1, a person applies excrement. When a person enters the private bathroom, the human sensor 4 is provided at an optimum position so that the human sensor 4 (see FIG. 2) can detect the human. When a human detection signal is obtained from the human sensor 4, the washing water pump (washing water P) 22 is operated by a signal from a control panel (control circuit) 6 provided at an appropriate position.

By the operation of the washing water pump 22, the treated water (medium water, urine 3) of the recycle tank 5 (mainly the treated water storage tank 9 in the recycle tank 5 in FIG. 2) and the treated water storage tank 9 and Chlorella bacteria 2 stored in the treated water reserve tank 10
4 mixed with water 11 mixed with water 4) at a flow rate controlled in advance by the control panel 6 and the flow control valve 17,
It is flushed into the toilet 1 through 6, 56.

As shown in FIG. 2, the recycle tank 5 mainly includes a solid-liquid separator 55 connected to the toilet 1 via a passage 54.
And a urine receiving tank 53 connected via a passage 14, a reaction tank 58 connected to the urine receiving tank 53 via a passage 57, and an activated carbon filtration tank connected to the reaction tank 58 via passages 59-61. 62, treated water storage tank 9 and treated water storage tank 9 and passage 6
The processing water reserve storage tank 65 is connected through the third and third storages 64. In addition, the urine receiving tank 53 communicates with a supply water intake port 66 for supplying water when the water 11 in the recycling tank 5 runs short.

The urine receiving tank 53, the reaction tank 58, the treated water storage tank 9, and the treated water preliminary storage tank 65 store a predetermined amount of the water 11 mixed with the chlorella bacteria 24 in advance. The recycling tank 5 (urine receiving tank 53, reaction tank 58, treated water storage tank 9)
And Chlorella bacteria 24 mixed in the treated water reserve tank 65)
It is preferable to use a seed of the chlorella bacterium 24, but the water 11 mixed with the chlorella bacterium 24 may be added in advance, or the chlorella bacterium 24 formed in a dry powder or solid form may be sprayed or charged. It may be.

Toilet bowl 1 provided in a private toilet (not shown)
When a person applies excrement, in this case, it is assumed that both the stool 2 and the urine 3 are excreted.
5, the urine 3 and the toilet flush water 4 are recycled through the passage 14 because the urine 3 and the urine 3 and the toilet flush water 4 have a structure having a mechanism for separating the urine 3 and the urine flush water 4. It is led to the tank 5.

Here, if the solid-liquid separator 55 is defined, the solid-liquid separator 55 is placed on the floor 88 or the toilet 1 on the ground.
When constructing the toilet 1, not only the lower passage, that is, the passage including the passage from which a person excretes excreta to the toilet 1 and reaches the stool processing tank 7 or the processing water storage tank 9. I do.

The stool 2 (the stool in this case includes solid toilet paper, etc .; the same applies hereinafter) falls in the direction controlled by the stool slide plate 25 below the hole 13 provided in the lower part of the toilet 1. . Stool 2 at this position is air compressor 23
The stool processing tank 7 is guided to the stool processing tank 7 through the passages 26 and 29 by the compressed air sent from the stool processing tank 7, and enters the stool processing tank 7 through the drop port 31 formed in the passage 29 at the upper position of the stool processing tank 7. Be dropped.

In this case, both the urinal 2 and the urinal 3 discharge the excrement into the urinal 1, so that the urinal and the urinal are not used separately, and the urinal and the urinal are not used. One toilet 1 having a structure that combines the above two is formed.

For this purpose, the toilet 1 has, for example, a structure in which a solid-liquid separator 55 for separating stool 2 and urine 3 and treated water (toilet flush water) 12 is formed as shown in FIG. That is, the urinal 1 or the lower passage is formed so that the urine 3 and the water 11 flowing along the inner wall of the urinal 1 flow toward the passage 14 connected to the recycle tank 5 described later. Is designed to be able to be separated. Therefore, the urine 3 and the treated water 12 hardly flow toward the stool processing tank 7, but mostly flow into the urine receiving tank 3 through the passage 14.

On the other hand, the stool 2 (including solid matter such as toilet paper) falls into the lower part of the hole 13 provided in the lower part of the toilet 1 in the same manner as a normal toilet. Here, since the toilet sensor is detected by the human sensor 4, the motor 32 is driven based on a signal from the control panel 6 to drive the stirring blade 32.
At the same time, the air compressor 23 operates based on a signal from the control panel 6, and the stool 2 that has fallen below the hole 13 by the compressed air is sent into the stool processing tank 7 through the passage 24.

At this time, the unpleasant odor is sent to a deodorization tower 38 through a passage 37 provided above the passage 29, where the deodorant 3
After being deodorized and piled up by 9, it is discharged to the outside through the passage 41 by the exhaust fan 40.

The stool processing tank 7 contains stool decomposition microorganisms 15. The stool-decomposing microorganism 15 is generally a microorganism in which a microorganism is supported on a moisture regulating material such as sawdust, and such a microorganism is also used here. However, it is not limited to such microorganisms,
Natural bacteria generated in the moisture control material, or powders or granular materials such as soybeans and corn, which carry microorganisms may be used. In any case, it is preferable to use a microorganism 15 that can dissolve feces and also decompose paper such as toilet paper used after excretion.

Paper such as stool 2 and toilet paper
The microorganisms 15 are mainly decomposed into carbon dioxide and water (steam) and disappear. The carbon dioxide generated at this time,
Steam (water) and other generated gases are sent to the deodorization tower 35 through the passage 49 to be deodorized and deodorized, and then discharged outside through the passage 37 by the exhaust fan 36.

The microorganism 15 used is not a humid bacterium but an aerobic bacterium because of contact with air. Therefore, it is necessary to bring air into contact with the stool and the microorganism-mixed treatment object 20 in which the stool 2 and the microorganism 15 to be fermented and decomposed in the stool processing tank 7 are mixed. For this reason, a stirring blade 32 for mixing and stirring the object 20 is rotatably provided in the stool processing tank 7.

The stirring blade 32 is rotated by a motor 32 via a shaft 51. The motor 32 is rotated by a timer in the control panel 6, a motor controller, and a driver,
At the time determined by the timer, the reciprocating rotation is performed for the time also determined by the motor controller.
Thereby, the object 20 in the stool processing tank 7 is stirred and brought into contact with air.

A heater 18 is provided on the outer periphery of the stool processing tank 7, and a mixture of microorganisms 15 and stool 2 (a stool and a mixture of microorganisms to be treated) 20 carried by a moisture adjusting material is provided at an appropriate position in the stool processing tank 7. A temperature sensor 19 for detecting a temperature is provided. The operation of the heater 18 is controlled by the temperature controller 21 based on the signal of the temperature sensor 19, and the microorganism-mixed article 20 in the stool processing tank 7 is maintained at an appropriate temperature.

The reason is that the microorganism 15 has its existence,
This is because there is an optimal temperature for the activity. The toilet system is often placed outside, but the activity of the microorganisms 15 is stopped in a cold season such as winter. Usually, the suitable temperature of the microorganism 15 is at or around the temperature of the human body, but the temperature varies depending on the microorganism. As the microorganism in this case, even a microorganism employed in a garbage disposer or the like can sufficiently decompose stool by fermentation. Here, those more suitable for stool decomposition are selected.

The treated water 12 including urine 3 guided into the recycling tank 5 is clean treated water 12 suitable for recycling.
To the urine receiving tank 53 in the recycling tank 5 via the passage 14 by the solid-liquid separator 55. The treated water 12 overflowing from the urine receiving tank 53 passes through the passage 57
Flows into the reaction tank 58 through The urine receiving tank 53 and the reaction tank 58 store the water 11 mixed with the chlorella bacteria 24 for eliminating the ammonia odor of the urine 3 and decomposing the urine 3 as described above.

Conventionally, since there is no optimum ammonia-decomposing bacterium and the maintenance thereof is troublesome, in the present invention, the chlorella bacterium 24 which can be easily handled and multiplied extremely easily in the urine receiving tank 53 and the reaction tank 58 is used. And water 11 to reduce costs and facilitate maintenance.

At the same time, in order to increase the growth of Chlorella bacteria 24 in each of the urine receiving tank 53 and the reaction tank 58, a fluorescent lamp 4
3 is inserted. The reason for using the transparent pipe 42 is to irradiate the light of the fluorescent lamp 43 to the chlorella bacteria 24 to insulate the fluorescent lamps 43.
4 in order to increase the number of cells.

The temperature sensor 28 and the heater 27 are inserted into the urine receiving tank 53 and / or the reaction tank 58, and the chlorella bacteria 24
The temperature of the treated water 12 in the urine receiving tank 53 or / and the reaction tank 58 is controlled by detecting the temperature of the treated water 12 containing Creating an optimal environment.

The chlorella bacterium 24 is a living thing, has the optimum temperature as described above, and the temperature may not be too low. Therefore, the heater 27 is used as described above. In addition, feeding oxygen increases the growth of Chlorella bacteria 24. Therefore, the air diffusers 50 and 67 are disposed in the lower part of the urine receiving tank 53 and the reaction tank 58, and the air is pumped from the air diffusers 50 and 67 based on the signal from the control panel 6.

On the other hand, the chlorella bacterium 24 functions to deodorize and decompose the urine 3 and to clean the toilet 1 and the like.
It is not good that the capacity of the activated carbon filtration tank 62 is exceeded. Therefore, the growth of Chlorella bacteria 24 is controlled to be appropriate.

Therefore, the urine receiving tank 53 and / or the reaction tank 5
A turbidity meter 45 is inserted into the chamber 8 so that the concentration of the chlorella bacteria 24 in the urine receiving tank 53 and / or the reaction tank 58 can be detected. The growth rate of Chlorella bacteria 24 varies depending on the temperature. Therefore, based on signals from the temperature sensor 28 and the turbidimeter 45, the temperature of the heater 27 and the
The illuminance of No. 3 is kept at an appropriate value, and is turned on or off so that the concentration of Chlorella bacteria 24 is maintained at an optimum value.

As the turbidity meter 45, for example, one configured as shown in FIG. 4 is used. Referring to FIG. 4, light emitting element 70 and light receiving element 71 are opposed to each other via a passage 68 in a transparent pipe 69 having a passage 68 into which Chlorella bacteria 24 enter.

If the concentration of Chlorella bacteria 24 in the passage 68 is different, the light receiving element 7 that receives the irradiation light from the light emitting element 70
1, the signal from the light receiving element 71 is input to the control circuit 72 in the control panel 6, and the control circuit 72 controls the temperature controller 44 to control the heater 27 and the fluorescent lamp 43. Illumination intensity, turn on or off.

The urine 3 that has entered the urine receiving tank 53 via the passage 14 by the solid-liquid separator 55 enters the reaction tank 58 via the passage 57, and the chlorella bacteria 24 in the urine receiving tank 53 and the reaction tank 58. Thus, the odor of the urine 3 is eliminated, and then the treated water 12 containing the urine 3 is filtered in the activated carbon filtration tank 62 through the filtration tank 73 and the passage 60. The overflowed treated water 2 in the activated carbon filtration tank 62 is circulated to the filtration tank 73 via the passage 61.

The treated water storage tank 9 communicates with the passages 63 and 64, and when the treated water 12 in the treated water storage tank 9 runs short, the treated water 12 in the treated water reserve tank 65 is passed through the passage 64. The treated water storage tank 9 is replenished. On the other hand, when the amount of the treated water 12 in the treated water storage tank 9 increases, the treated water 12 is
I send it in.

In the treated water storage tank 9, the treated water 12
Upper limit liquid level sensor 3 at the upper position to detect the liquid level
0-1 and a lower limit liquid level sensor 3 at the lower position.
0-2 is arranged. The upper limit liquid level sensor 30-1
The lower limit liquid level sensor 30-2 may be constituted by one sensor, but in this embodiment, two sensors are used.

The upper limit liquid level sensor 30-1 is for limiting the upper limit of the liquid level of the treated water 12 in the treated water storage tank 9. When the liquid level upper limit signal is obtained, the control panel 6 outputs the signal. The suction pump 47 is driven based on the signal to feed the treated water 12 into the activated carbon filtration tank 62 through the passages 76 and 77 at a flow rate controlled by the flow rate control valve 74.

When a liquid level upper limit signal is obtained from the liquid level sensor 30-1 for upper limit, the suction pump 47 is driven based on the signal from the control panel 6 to drive the passage 78 with the flow rate adjusted by the flow rate adjusting valve 75. The treated water 12 is sent into the stool processing tank 7 through the stool processing tank 7. Here, chlorella bacteria 24 are mixed in the treated water 12, so that the stool 2
Promotes decomposition.

Furthermore, when a liquid level upper limit signal is obtained from the upper limit liquid level sensor 30-1, the suction pump 47 is driven based on the signal from the control panel 6 to send the treated water 12 into the water generating tank 48 and at the same time. Until the upper limit signal from the upper limit liquid level sensor 30-1 is no longer present, the steamer 46 is operated to evaporate the treated water 12 in the water generating tank 48 and disperse it to the outside. Since the steamer 46 only has to evaporate the treated water 12 in the water generating tank 48, appropriate means such as a heater, a humidifier, or an ultrasonic humidifier may be used.

When a liquid level upper limit signal is obtained from the liquid level sensor 30-1 for the upper limit, an alarm buzzer 79 provided at an appropriate position in the toilet private room is configured to sound and the alarm lamp 80 is also turned on. It has become. The sounding of the alarm buzzer 79 and the turning off of the alarm lamp 80 can be performed by turning on the alarm release switch 81.

The lower limit liquid level sensor 30-2 is for restricting the lower limit of the liquid level of the treated water 12 in the treated water storage tank 9, and a lower limit liquid level signal is obtained from the lower limit liquid level sensor 30-2. When the alarm buzzer 7 is installed, the alarm buzzer 7
9 is sounded, and the alarm lamp 80 is also turned on. The sounding of the alarm buzzer 79 and the turning off of the alarm lamp 80 are performed by an alarm release switch 81.
By turning on.

The treated water reserve storage tank 65 is connected to an overflow tank / evaporation tank 83 via a passage 82, and the treated water 12 overflowing the treated water preliminary storage tank 65 flows into the overflow tank / evaporation tank 83, Evaporated and released to the outside.

The microorganisms 15 in the stool processing tank 7 are:
Since an appropriate water is required, the microorganism-mixed treatment object 20
When the water content in the inside of the passage 8 decreases, the makeup water pump (make-up water P) 84 operates based on the signal from the control panel 6 and
The treated water 12 in the activated carbon filtration tank 62 is supplied into the stool processing tank 7 through the flow control valve 87 and the flow control valve 87 and the passage 78.

When a person in the toilet room of the toilet system completes defecation and the motion sensor 4 stops sensing a person,
The operation of the flush water pump 22 is stopped by a signal from the control panel 6, and the supply of the treated water 12 into the toilet 1 is stopped.

According to the present invention, a chlorella bacterium which is easy to handle, proliferate, and inexpensive for deodorizing the ammonia odor of urine is used, so that a clean and easy-to-maintain toilet system can be easily provided. In addition, a method of deodorizing a toilet or the like that can be formed at low cost can be realized.

Further, by adopting the above method, it is not necessary to dispose a stool treatment tank immediately below the toilet, and it is possible to dispose it on the floor or on the ground. Alternatively, a water-circulating toilet system that decomposes excreta by using microorganisms having excellent versatility can be easily and inexpensively provided because it can be disposed under the ground.
