In the reaction tank, microorganisms that decompose the previously-implanted organic liquid are added, and the supernatant liquid of the sedimentation tank is sprinkled from above, and the liquid that has passed while contacting the microorganisms that have been implanted is drained from below. , Sent to the wash water tank.

However, although the supernatant liquid of the sedimentation tank is sprinkled into the reaction tank, the toilet paper left undecomposed from the sedimentation tank and the residue such as solid waste matter flow into the reaction tank. The residue solidifies as a film on the surface of the reaction tank. Therefore, the flow to the lower layer of the reaction tank is deteriorated, and the activity of microorganisms is suppressed. Furthermore, the residue accumulates in the reaction tank, and it is necessary to remove the residue.

Therefore, an object of the present invention is to provide a toilet device that can efficiently perform decomposition processing in a reaction tank.

The toilet device of the present invention is filled with a carrier on which microorganisms for decomposing the treated water are implanted in order to reuse the treated water obtained by treating the waste from the toilet bowl as the wash water for discharging the waste from the toilet bowl. A reaction tank having a sprinkling pipe for sprinkling the treated water from above the carrier, wherein the size of the carrier is such that the upper layer of the reaction tank is formed larger than the lower layer side, and the reaction tank has It is characterized in that an air diffusing tube for arranging air is arranged.

According to the toilet device of the present invention, the treated water sprinkled from the sprinkling pipe is decomposed by the microorganisms implanted on the carrier. Regarding the size of the carrier packed in the reaction tank, the upper layer of the reaction tank is formed to be larger than the lower layer side. Therefore, even if the waste water remains in the treated water sprinkled from above, it easily penetrates into the gap between the upper-layer carriers. Therefore, since the dirt penetrates into the gaps of the carrier and is divided by the carrier, it is possible to prevent the dirt from accumulating on the surface layer of the carrier and solidifying into a film, and allowing the treated water to permeate to the lower layer side. Further, the air from the air diffuser is sent into the carrier in the reaction tank. Therefore, the aerobic microorganisms implanted on the carrier are activated, and the decomposition treatment by the microorganisms is promoted.

The carrier may be formed by a plurality of layers compressed for each layer. By compressing the carrier layer by layer, the gap between the carriers becomes smaller, and thus the reaction tank can be filled with more carriers, so that the treated water can be brought into contact with more carriers.

The upper carrier layer of the plurality of layers may be a non-compressed layer. By making the upper carrier layer a non-compressed layer, it is possible to easily permeate the filth sprinkled with water from the water sprinkling pipe.

The air diffuser may be arranged so as to extend upward from the lower end of the reaction tank. The air rises from the lower end of the reaction tank to the upper side by diffusing the air into the treated water that permeates the carrier from the lower end of the reaction tank. Therefore, the air can be evenly distributed in the reaction tank, and the microorganisms implanted on the carrier can be activated.

The carrier around the air diffuser may have a larger size when the distance from the air diffuser is closer. By increasing the size of the carrier close to the air diffuser, the gap between the carriers around the air diffuser can be increased. Therefore, the air from the air diffuser can be smoothly sent from the large-sized carrier to the small-sized carrier.

The air diffuser is a receiving tank that stores the waste from the toilet, a decomposition tank that decomposes the waste from the receiving tank with microorganisms, and a residue is settled and separated from the treated water in which the waste is decomposed by the decomposition tank. It may be connected to an air supply pipe from at least one of the sedimentation tanks. By releasing the odor from any of the receiving tank, the decomposition tank or the sedimentation tank into the carrier of the reaction tank through the air diffuser, the microorganisms can be deodorized while being activated while the microorganisms are being decomposed.

According to the toilet device of the present invention, it is possible to prevent filth from accumulating on the surface layer of the carrier and forming a film, and allowing the treated water to permeate to the lower layer side. Since the implanted aerobic microorganisms are activated and the decomposition treatment is promoted, the decomposition treatment in the reaction tank can be efficiently performed.

(Explanation of the second settling tank/dirt tank)
Next, the second settling tank 42 and the waste tank 70 will be described in detail with reference to FIG.
In the second settling tank 42, a plurality of flow pipes meandering vertically are connected in series. In the present embodiment, the second settling tank 42 is a three-stage settling tank in which the first to third flow pipes 421 to 423 formed in a V shape or a U shape are connected.

In the first flow pipe 421, a horizontally extending first discharge pipe 411 is connected to an upper portion of one branch pipe, extends downward from the upper portion, and is folded back at a lower end which is a valley portion, and then at the upper portion of the other branch pipe. Therefore, the second circulation pipe 422 is connected to the upper portion of the position lower than the connection position of the first discharge pipe 411.

The second distribution pipe 422 is connected to the third distribution pipe 423 at the upper part of the other branch pipe, which is lower than the connection position of the first distribution pipe 421.
Further, the third flow pipe 423 is an upper part of the other branch pipe, which is lower than the connection position of the second flow pipe 422, and is provided with a treated water flow pipe 424 to the reaction tank 50 (see FIG. 4 ). Are connected.

The filth tank 70 stores filth from the fourth discharge pipe 425 of the second settling tank 42, filth from the third discharge pipe 413, and filth from the second discharge pipe 412. Further, the filth tank 70 also stores filth from the reaction tank 50 (see FIG. 4). The filth tank 70 is provided with a pump 71 for returning the filth collected at the bottom to the receiving tank 20 (see FIG. 1).

(Explanation of reaction tank)
Next, the reaction tank 50 will be described in detail with reference to FIG.
The reaction tank 50 integrally includes a first tank 50a that functions as a pre-treatment water storage portion 51, a second tank 50b that functions as a reaction portion 52, and a third tank 50c that functions as a post-treatment water storage portion 53. It is a thing.
The treated water passage pipe 424 from the second settling tank 42 is connected to the side wall of the first tank 50a. At the lower end of the first tank 50a, a fifth discharge pipe 511 for discharging the waste settled in the pretreatment water storage section 51 to the waste tank 70 is connected. The fifth discharge pipe 511 is provided with a valve 512 whose opening and closing is electrically controlled.
Inside the first tank 50a, a pump 513 for pumping up the treated water accumulated in the reaction section 52 is arranged.

In the upper space of the second tank 50b, a sprinkling pipe 521 for sprinkling the treated water pumped by the pump 513 is arranged.
An air diffuser 522 is arranged below the second tank 50b so as to extend upward from the lower end. Inside the second tank 50b, carriers 523 for implanting microorganisms are stacked with the air diffuser 522 embedded. As the carrier 523, the wood chips used in the decomposition tank 30 can be used. The carrier 523 is formed such that the upper layer of the second tank 50b of the reaction tank 50 is larger than the lower layer side.

The carrier 523 is formed of a plurality of layers. In this embodiment, the uppermost carrier layer 523a is formed in a medium size, and the carrier layers 523b to 523f, which are lower layers than the carrier layer 523a, are formed in a small size.
Further, the carrier 523 located around the air diffuser 522 is formed to have a larger size when the distance from the air diffuser 522 is shorter. In the present embodiment, the lowermost carrier layer 523g located around the air diffuser 522 is formed in a large size, and the carrier layer 523h around the carrier layer 523g is formed in a medium size.

For example, the small size may be an elongated piece of wood with a width of about 2-3 mm and a length of about 5 mm to 1 cm. The medium size may be a block-like piece of wood with a width of about 5 mm to 1 cm, a length of about 1 cm and a thickness of about 5 mm to 1 cm. The large size may be a block or plate-like piece of wood with a width of about 1 cm to 2 cm, a length of about 3 cm to 5 cm, and a thickness of about 2 mm to 1 cm. In addition, the carrier 523 of each size may be mixed with other size pieces of wood, bark, wood powder, or the like.

The carrier 523 is compressed layer by layer. The carrier 523 may be compressed while being compressed by a compressor from above, or may be stacked by the manufacturer while stepping on it with a foot if no compressor is provided. In this embodiment, after the carrier layers 523g and 523h are put in, the carrier layers 523b to 523f except the carrier layer 523a are stacked while being compressed.

The air diffuser 522 is connected to a lid 113 (see FIG. 2) of the housing 110, and an air supply pipe 524 from the receiving tank 20 and the wash water tank 60 (see FIG. 1). A blower 525 is provided on the air supply pipe 524, and the air blower 525 blows off the odors in the decomposition tank 30, the first settling tank 41, the receiving tank 20, and the wash water tank 60 to the air diffusion pipe 522.
The third tank 50c located below the second tank 50b is provided with a pump 531 that pumps up the cleaning water that has passed through the reaction section 52, which is the second tank 50b, and pumps it to the cleaning water tank 60.

The operation and usage state of the toilet device 1 according to the embodiment of the present invention configured as described above will be described based on the drawings.
When the user completes excretion and flushes the excrement and the toilet paper waste from the toilet 10 shown in FIG. 1 with the wash water, it is crushed by the drainage pressure crushing pump 11 and pressure-fed to the receiving tank 20.
In the receiving tank 20, excrement and filth such as toilet paper are discharged from the air diffuser by blowing air from the blower, and the filth is in a state of sufficiently containing air and is sent to the decomposition tank 30.

In the decomposition tank 30 shown in FIG. 2, filth is first sent to the aerobic tank 31. In the aerobic tank 31, aerobic microorganisms are implanted on the carrier 314 by the air discharged from the bottom portion 311 by the air diffusing pipe 313 to decompose the waste in the aerobic tank 31. Then, the filth collected higher than the first partition wall 111 moves to the next anaerobic tank 32 by natural flow.

In the anaerobic tank 32, the anaerobic microorganisms implanted on the carrier 323 of the bottom portion 321 are decomposed. In the anaerobic tank 32, since the detour plate 322 hangs down from the upper part, the filth is brought into contact with the carrier 323 and moves from the first partition wall 111 side to the second partition wall 112 side, so that decomposition treatment by anaerobic microorganisms is performed. Is effectively done.
By decomposing by the aerobic tank 31 and the anaerobic tank 32, filth is purified and becomes treated water, and the treated water that has exceeded the second partition wall 112 moves from the anaerobic tank 32 to the first settling tank 41 by natural flow. To do.

In the first settling tank 41, the residue that has not been decomposed in the decomposition tank 30 settles and accumulates on the bottom portion 41a. Further, in the first settling tank 41, a residue having a specific gravity smaller than that of water floats in the treated water.
Therefore, since the middle layer of the treated water collected in the first settling tank 41 is in the clearest state, the treated water of the middle layer is taken into the first discharge pipe 411 while avoiding the upper and lower filth, and the first layer shown in FIG. 2 Pour into the settling tank 42.

In this way, the first discharge pipe 411 allows the treated water in the clearest state accumulated in the first settling tank 41 to be sent to the second settling tank 42, so that the reaction tank 50 and the washing water tank 60 are sufficiently purified. The treated water can be sent. Therefore, clean water that is reused can be used.

In the second settling tank 42 shown in FIG. 3, the first flow pipe 421 to the third flow pipe 423 pass through the first flow pipe 421 to the third flow pipe 423 while sequentially flowing down, and the lower ends of the first flow pipe 421 to the third flow pipe 423 respectively. The residue settles on. While passing through the second settling tank 42, the further purified purified water flows into the reaction tank 50.
As described above, in the second settling tank 42, the pipes formed from the first flow pipe 421 to the third flow pipe 423 in a V shape or a U shape are connected in series in a plurality of stages to allow the treated water to flow naturally. Since the filth is settled while the filth is set, the height required to settle the filth can be suppressed. Therefore, even if the height of the second settling tank 42 is lowered, it is possible to surely settle the filth from the treated water and further purify it.

In the reaction tank 50 shown in FIG. 4, the treated water is temporarily stored in the pretreatment water storage section 51. Then, the treated water pumped up by the pump 513 is sprinkled by the sprinkling pipe 521 at the upper part of the reaction section 52 (second tank 50b). The treated water is sprinkled from above the carrier 523 and permeates, but the upper carrier layer 523a is a medium size, which is larger in size than the small-sized carrier layers 523b to 523f on the lower layer side. Therefore, even if the treated water in which filth remains, the filth easily penetrates into the gap of the upper carrier layer 523a. Further, unlike the carrier layers 523b to 523f, the upper carrier layer 523a is a non-compressed layer that is not compressed, so that it is possible to easily permeate the filth sprayed from the water spray pipe 521.

Therefore, the filth contained in the treated water that has permeated into the carrier layer 523a is divided by the wood pieces by permeating into the gaps between the wood pieces, so that the filth is prevented from being deposited on the surface layer of the carrier layer 523a and solidifying into a film. Therefore, the treated water can permeate to the lower layer side.

The treated water containing filth that has passed through the carrier layer 523a permeates the small-sized carrier layers 523b to 523f. Furthermore, it penetrates into medium-sized and large-sized carrier layers 523g and 523h.
Aerobic microorganisms are implanted in the carrier layers 523a to 523h, and the air from the blower 525 is diffused from the air diffuser 522 arranged in the lower part of the reaction section 52. Therefore, since the air diffused from the air diffuser 522 spreads to the carrier layers 523a to 523h, the decomposition treatment by the microorganisms is promoted, so that the dirt contained in the treated water that permeates the carrier layers 523a to 523h is decomposed, Purified.

The carrier layers 523b to 523f are formed by a plurality of layers compressed for each layer. Therefore, since the gap between the carriers 523 becomes small, the reaction unit 52 can be filled with a large amount of the carriers 523, and thus the treated water can be brought into contact with a large amount of the carriers 523.

A large-sized carrier layer 523g is arranged around the air diffuser 522, and a medium-sized carrier layer 523h is further arranged around the air diffuser 522. Therefore, the air from the air diffuser 522 is first sent to the large-sized carrier layer 523g and advances through the gap, and further advances through the gap of the medium-sized carrier layer 523h to the small-sized carrier layers 523f to 523a. proceed.

In this way, by increasing the size of the carrier 523 closer to the air diffuser 522, the gap between the carriers 523 around the air diffuser 522 can be increased, so that the air from the air diffuser 522 is sized. The carrier 523 having a large size can be smoothly fed to the carrier 523 having a small size.

Therefore, contrary to the carrier layers 523a to 523h in which the treated water permeates from the upper layer to the lower layer side, the air from the air diffuser 522 permeates the carrier 523 from the lower layer to the upper carrier layers 523h to 523a. It can be smoothly sent to treated water. Therefore, the air can be evenly distributed in the reaction section 52, and the microorganisms implanted on the carrier 523 can be activated.

Here, the air sent to the air diffuser 522 and activating the aerobic microorganisms will be described with reference to FIG.
As shown in FIG. 5, as described above, the receiving tank 20 and the wash water tank 60 are formed inside the housing 120. Further, as shown in FIG. 2, a decomposition tank 30 (aerobic tank 31, anaerobic tank 32) and a first settling tank 41 are formed inside the housing 110.
An air supply pipe 524, which is connected to the air diffusion pipe 522 of the reaction tank 50 and in which a blower 525 is interposed, is connected to the housings 110 and 120.

With this configuration, the odor generated by the aerobic tank 31, the anaerobic tank 32, and the first settling tank 41 in the housing 110 and the odor generated by the receiving tank 20 and the wash water tank 60 in the housing 120 are scattered. By radiating from the trachea 522 into the carrier 523 of the reaction part 52, it is possible to deodorize the microorganism by decomposing the microorganism while activating the microorganism.
Therefore, it is possible to suppress the offensive odor that a user excreted by the toilet 10 shown in FIG. 1 or a person around the toilet device 1 feels uncomfortable.

In the present embodiment, the air supply pipe 524 is connected to all of the receiving tank 20, the decomposition tank 30, and the first settling tank 41, but at least one of them may be connected. However, it is preferable to connect all the air supply pipes 524 because it can suppress the generation of unpleasant odor.

In the above example, as the carrier 523 filled in the reaction section 52, there are two types of carriers, that is, the medium size carrier layer 523a of the upper layer and the small size carrier layers 523b to 523f below the carrier layer 523a. The carriers 523 having the above sizes may be arranged so that the upper layer is larger than the lower layer side.
Further, as the carrier 523 around the air diffusing pipe 522, there are two types of carriers, that is, a large-sized carrier layer 523g and a medium-sized carrier layer 523h, but carriers of three or more sizes are close to the air diffusing pipe 522. The size of the carrier 523 may be increased.

The treated water purified by the reaction section 52 becomes cleaning water and drops into the treated water storage section 53 (third tank 50c). Then, the cleaning water that has been dripped and accumulated in the water storage section 53 after processing is sent to the cleaning water tank 60 shown in FIG. 1 by the pump 531. The flush water accumulated in the flush water tank 60 is again discharged to the toilet bowl 10 by the user and discharged and then used again.

On the other hand, the dirt settled on the bottom portion 41a of the first settling tank 41 shown in FIGS. 2 and 6 flows into the third discharge pipe 413. Therefore, since the third discharge pipe 413 causes the filth settling in the lower layer to flow into the filth tank 70, the filth can be removed from the treated water in the lower layer of the first settling tank 41. The valve 413a (see FIG. 2) provided in the third discharge pipe 413 is normally used in an open state, and thus the electric flow of water flowing through the third discharge pipe 413 is controlled by the electric valve 413b. ..

Further, the filth floating in the treated water accumulated in the first settling tank 41 flows into the second discharge pipe 412. Therefore, since the second discharge pipe 412 causes the filth floating in the upper layer to flow into the intake port 412a and send it to the filth tank 70, the filth can be removed from the treated water in the upper layer of the first settling tank 41. Water flow of the waste flowing into the second discharge pipe 412 is controlled by the electric valve 412b.

The waste that has settled from the first flow pipe 421 of the second settling tank 42 shown in FIGS. 3 and 6 to the bottom of the third flow pipe 423 flows into the branch pipe 425 b of the fourth discharge pipe 425. Therefore, the fourth discharge pipe 425 sends the waste settled in the second settling tank 42 to the waste tank 70, so that the waste can be removed from the second settling tank 42. Water flow is controlled by electric valves 426a to 426c provided on the branch pipe 425b of the fourth discharge pipe 425.

The waste that has settled at the bottom of the pre-treatment water storage portion 51 (first tank 50a) of the reaction tank 50 shown in FIGS. 4 and 6 flows into the fifth discharge pipe 511. Therefore, since the fifth discharge pipe 511 sends the sedimented waste to the waste tank 70, the waste can be removed from the pretreatment water storage section 51. The water flow of the waste flowing into the fifth discharge pipe 511 is controlled by an electric valve 512.

Of the excrement, stool or toilet paper is crushed by the drainage pressure crushing pump 11 and pressure-fed, and while passing through the reaction tank 50 from the receiving tank 20, it becomes finer and contains water and air to have a lower specific gravity. Therefore, the filth contained in the treated water that has flowed into the first settling tank 41 floats in the upper layer, and thus has the most filth and has a thick layer. Although the filth having a specific gravity larger than that of water even after passing through the reaction tank 50 is deposited and deposited in the lower layer, the amount thereof is smaller than the filth floating in the upper layer of the treated water.

Since the treated water of the middle layer in the first settling tank 41 is in the clearest state as compared with the treated water of the upper layer and the lower layer, the filth contained in the treated water settles when passing through the second settling tank 42. Even if accumulated, the amount is smaller than that of the waste settled in the first settling tank 41.

Further, since the treated water in the pre-treatment water storage section 51 of the reaction tank 50 is purified every time it passes through the first settling tank 41 and the second settling tank 42, the amount of filth contained in the treated water is the second settling tank. It is even smaller than the amount of waste that settles when passing through the tank 42.

Therefore, the control unit 80 controls opening/closing of the valve 412b, the valve 413b, the valves 426a to 426c, or the valve 512 with a time lag according to the amount of waste.
For example, as shown in FIGS. 6 and 7, the control unit 80 opens the valve 412b of the second discharge pipe 412 in the first settling tank 41 in which the amount of filth is the largest every hour.
In addition, the control unit 80 opens the valve 413b of the third discharge pipe 413 in the first settling tank 41 in which a large amount of filth flows next every 3 hours.
Further, the control unit 80 controls the valves 426a to 426c provided on the branch pipe 425b of the fourth discharge pipe 425 through which the smallest amount of filth flows and the valve 512 provided on the fifth discharge pipe 511 of the pretreatment water storage unit 51. Open every hour.
The time interval for opening the valves (412b, 413b, 426a to 426c, 512) can be set in the control unit 80 by inputting from an operation panel (not shown).

If the valve is opened in a state where the waste is not sufficiently accumulated, the purified treated water flows into the waste tank 70 together with the waste, so that not only the amount of waste discharged from the waste tank 70 but also The effluent purified treated water also needs to be considered in determining the size of the waste tank 70.
However, since the control unit 80 opens the valves 412b, 413b, 426a to 426c, 512 with a time lag according to the amount of filth, the valves are opened in a state where the filth is sufficiently accumulated. It is possible to prevent a large amount of clear treated water from flowing into the waste tank 70 together with the waste.

Therefore, the sewage tank 70 does not have to be oversized, and the treated water does not easily flow into the sewage tank 70. Therefore, a sufficient amount of purified treated water is sent from the reaction tank 50 to the washing water tank 60. Therefore, it is possible to secure a sufficient amount of washing water.

In the above example, the control unit 80 opened each valve at regular time intervals. However, for example, a sensor that detects that flush water has been flushed with the toilet bowl 10 shown in FIG. Alternatively, the control unit 80 may adjust the time interval according to the discharge frequency of the waste detected by the sensor.
Further, if the sensor is used to detect urine and stool separately, the control unit 80 may adjust the time interval according to the frequency of urine discharge.

For example, the treated water containing filth has a higher viscosity than the clarified and treated clarified water, so it takes time for the filth to pass through the valve and reach the filth tank 70, and the filth is washed away. Only power is needed. The control unit 80 adjusts the opening time of each of the valves 412b, 413b, 426a to 426c, 512 by a setting input from an operation panel (not shown). Therefore, depending on the amount of filth or the installation environment of the toilet device, by setting the opening time of the valve longer, it is possible to reduce the amount of filth remaining in each tank when the valve is opened. ..

In the present embodiment, the settling tank 40 is of a two-stage type consisting of the first settling tank 41 and the second settling tank 42, and the treated water is taken out from the middle layer of the first settling tank 41 and flowed to the second settling tank 42. Was there. For example, when the settling tank is composed of three or more stages, any one of the second and subsequent settling tanks is set as the front stage, and when the treated water is sent from this front stage settling tank to the next settling tank, It is possible to take out the treated water from the middle layer of the settling tank and let it flow to the next stage, and to send the filth floating in the upper layer and the filth settling in the lower layer to the sewage tank.

INDUSTRIAL APPLICABILITY The present invention is suitable for a toilet device that reuses treated water obtained by treating waste from a toilet bowl as cleaning water for discharging the waste from the toilet bowl, so that an outdoor event or a disaster, a mountain, the sea, a river, etc. It can be applied to toilet equipment installed and used in.
