Description

  The present invention relates to a flush toilet system that can be used even when the water supply and sewerage systems cannot be used.

  2. Description of the Related Art Conventionally, a flush toilet has been known in which a toilet bowl is washed with water from a water supply whenever it is excreted. Such flush toilets cannot be used when water and sewage systems cannot be secured, such as during a disaster.

  Therefore, for example, when a water supply cannot be secured over the long and medium term, such as during a disaster, a temporary toilet is generally used.

  As such a temporary toilet, a draw-up type toilet has been known. However, if the odor, hygiene problem, and filth become full, this draw-up type toilet must be pumped up. There was a problem that it could not be used.

  Therefore, a circulating flush toilet called a self-processing type is known as a toilet that solves the odor and sanitary problems of the flush toilet (for example, see Patent Document 1).

  This prior art is a sewage treatment means capable of performing a water purification treatment such as aeration on waste water from a toilet in stages, and finally separating it into a precipitate and supernatant water to obtain reusable treated water. have. Thus, it is called a self-treatment type because sewage can be purified in the toilet system.

Furthermore, in the above prior art, the treated water obtained by the sewage treatment means is always pumped between the toilet bowl and the sewage treatment means so that the sewage treatment means is pumped up and sent back to the toilet as washing water. It tries to circulate.

A self-treatment type sewage treatment means configured to be operable, and having a capacity connected to a water supply and capable of storing an amount of water necessary for the initial operation of the circulating water purification operation of the sewage treatment means, and A flushing mode flow path capable of supplying water to a toilet, wherein the flushing mode is connected to the water supply mode and the flushing mode flow path when the flushing mode is used. In the state where the execution of the circulating water purification operation of the sewage treatment means is stopped, the water supply of the water supply is introduced into the water washing mode flow path, and the water washing mode flow path uses the circulating water purification operation. The amount of water required for the initial operation of Use it in a one-way flow from the water supply to the sewer so that the wastewater from this toilet is drained to the sewer, and use the flush mode when using the self-treatment circulation mode. Sometimes the sewage treatment means is circulated and purified using the clean water stored in the flush mode flow path for the initial operation, and the treated water purified by the sewage treatment means is supplied to the toilet as wash water. On the other hand, the water that has passed through the toilet is returned to the sewage treatment means and used again in a circulating flow for water purification treatment.

  In the toilet system of the present invention, the water flow mode switching means can be used as a normal flush toilet in the flush mode at normal times when water supply and sewerage can be secured.

  In this water washing mode, the execution of the circulating water purification operation of the sewage treatment means is stopped. And the tap water from a water supply is supplied to a toilet bowl through the flow path for flush modes, and is drained to a sewer. In this flush mode flow path, an amount of water necessary for the initial operation of the sewage treatment means is stored.

  On the other hand, in an emergency such as a disaster where at least one of the water supply and the sewerage is not ensured, the water flow mode switching means is set to the self-treatment circulation mode, and the sewage treatment means is circulated and purified.

  When this sewage treatment means is operated in a circulating water purification operation, the clean water stored in the flush mode flow path can be used for the initial operation.

  And in this self-processing circulation mode, the waste water from a toilet bowl is purified by the sewage treatment means, and the treated water is sent to the toilet bowl again.

  As described above, in the present invention, during normal times when water and sewage is secured, the circulating water purification operation of the sewage treatment means is stopped and used as a water washing mode, so running by reducing power consumption in the sewage treatment means. Cost can be kept low.

  Moreover, since the water stored in the flow channel for the water washing mode can be used for the initial operation of the sewage treatment means when used in the water washing mode, the water for the initial operation is conveyed in an emergency in which water supply or sewerage cannot be secured. Therefore, the sewage treatment means can be immediately circulated and purified and the emergency response is excellent.

  In addition, a predetermined amount of clean water is stored in the flush mode flow path in the flush mode as described above. However, in this flush mode flow path, there is a flow from the water supply to the sewer, so water is stored for a long time. Even if it does, the malfunction which water rots and emits a bad smell does not arise.

  According to the second aspect of the present invention, in the flush mode, the tap water supplied from the water supply to the flush mode channel is fed toward the toilet bowl with the water head pressure.

  Therefore, it is not necessary to pump up water using a pump or the like in the water washing mode, and power consumption in the water washing mode can be eliminated, thereby further reducing the running cost.

  In the third aspect of the present invention, since the flush mode channel is formed using the existing sewage treatment means, the flush mode channel is formed separately from the sewage treatment means. Compared to the above, the number of components can be reduced and the installation space can be reduced.

  In addition, since the water for the initial operation is stored inside the sewage treatment means, it is possible to reduce the effort of moving the stored water during the initial operation of the sewage treatment means.

  In the invention described in claim 4, when used in the self-processing circulation mode, the clean water stored in the storage chamber in the water washing mode is supplied to the lower chamber from the drain passage by opening the drain valve. Since this storage chamber is a chamber for storing the sediment of sewage during the circulating water supply operation, no water is required during the initial operation, so that the entire amount can be supplied to the lower chamber.

  Thus, in the invention described in claim 4, in the sewage treatment means, the water for initial operation of the lower chamber is stored by using the storage chamber for storing the sediment of sewage during the circulating water purification operation. Therefore, compared with newly setting a tank for storing the water for the lower chamber, the space of the entire toilet system can be kept small and can be configured compactly. It should be noted that the reason why water is not stored in the lower chamber during the flush mode is that the lower chamber cannot supply water to the toilet bowl with water head pressure. Because there is.

  According to the fifth aspect of the present invention, the water supply switching means, the drainage switching means, and the toilet flushing switching means are switched to the flush mode during the flush mode. Thus, the water supply system and the flush channel for the upper chamber are connected by the water supply channel, and the flush mode channel is a channel that bypasses the water tank and reaches the toilet. Connected to the sewer.

  In this flush mode, clean water is introduced and stored in the flush mode channel formed in the upper chamber from the tap water through the clean water supply channel. Moreover, the clean water stored in this flush mode channel is sent to the water tank by the head pressure. Then, when the washing switching means is operated after the toilet is used, an amount of water necessary for one washing of the toilet stored in the water tank is poured into the toilet, and the toilet is washed and flows into the sewer. Also, in the water tank, when the water level drops due to the use of water, the valve means opens and the flush mode channel is opened to supply water, and when the water level rises to a predetermined level, the valve means closes and the water supply stops. Is done. The above operation is repeated each time the toilet is used.

  On the other hand, in the self-processing circulation mode, the water supply switching means, the drainage switching means, and the toilet bowl washing switching means are switched to the self-processing circulation mode. As a result, the water supply path is blocked by the water supply switching means, and the flush mode flow path in the upper chamber of the sewage treatment means is a flow path directly connected to the toilet by the water supply path without detouring to the water tank. The toilet bowl is connected to the lower chamber of the sewage treatment means through the drainage channel.

  In this self-processing circulation mode, the water that has washed the toilet bowl is drained to the lower chamber of the sewage treatment means, pumped from the lower chamber to the upper chamber, and purified in the process, and then sent to the toilet bowl again. Cycle the washing of the toilet bowl.

  As described above, in the invention according to the fifth aspect, the water tank is provided in the flow channel for the water washing mode, and in the water washing mode, an amount of water necessary for one washing of the toilet stored in the water tank is allowed to flow. As a result, the use of clean water can be minimized.

  On the other hand, in the self-treatment circulation mode, the wash water treated by the sewage treatment means is constantly circulated to the toilet, the excrement is drained immediately, and it is hygienic. Made.

  Moreover, the clean water supply switching means, the drainage switching means, and the toilet flushing switching means that constitute the water flow mode switching means can be configured by a valve that simply switches the flow path, and the manufacturing cost can be kept low.

  In the sixth aspect of the present invention, in the flush mode, the water supply of the water supply is supplied to the storage chamber, the storage chamber becomes full and overflows to the fluid contact chamber through the overflow path, and the fluid contact chamber is It becomes full and overflows into the separation chamber. Furthermore, this separation chamber becomes full and overflows into the water supply chamber.

  And the clean water stored by this water supply chamber is supplied toward a toilet bowl. Further, when the water level in the water supply chamber is lowered to a predetermined height due to this water supply, the float valve is opened and supply of clean water to the storage chamber is performed. With this supply, the storage chamber, the fluid contact chamber, the separation chamber, and the water supply chamber are overflowed in this order, and when the water level in the water supply chamber rises to a predetermined level, the float valve closes and rises to the storage chamber. Water supply is stopped.

  Thus, in the water washing mode, in the upper chamber of the sewage treatment means, the storage chamber, the fluid contact chamber, and the separation chamber are all maintained in full water, and the water supply chamber is also maintained at a predetermined water level for initial operation. Water can be reliably stored. Further, in the storage chamber, the fluid contact chamber, the separation chamber, and the water supply chamber constituting the flush mode flow channel, it is always possible to reliably prevent the water from being spoiled by the flow of clean water.

  On the other hand, in the self-processing circulation mode, the waste water from the toilet bowl is sent to the fluidized stirring chamber, where it is stirred to crush and deodorize filth. Further, the sewage in the fluidized stirring chamber is sent to the fluidized contact chamber by a return pump, where it is aerated and deodorized. Further, the sewage that has flowed over the fluid contact chamber and sent to the separation chamber is separated into supernatant water and sediment, and the supernatant water flows over to the water feeding chamber. And the supernatant water of a water supply chamber, ie, treated water, is sent to a toilet bowl as washing water. The sediment in the separation chamber is appropriately pumped into the storage chamber by the pumping means.

  In the invention according to claim 7, when sewerage is secured during the self-processing circulation mode, the sewage sediment stored in the storage chamber is opened by opening the sewage discharge valve of the second overflow path, It can be discharged into sewage at any time.

  Therefore, in the invention described in claim 7, since the sediment in the toilet system can be discharged to the sewage outside the toilet system, the toilet system is not filled with filth, and the circulating water purification operation is continued for a long time. Can do.

  In the invention according to claim 8, when the water supply is restored and returned to the water washing mode after being used in the self-treatment circulation mode, all of the sewage stored in the sewage treatment means is allowed to flow into the sewer as follows. be able to.

  That is, when the return switching valve is set to the cleaning mode and the return pump is pumped up and driven, the sewage stored in the flow stirring chamber can flow into the sewer.

  In addition, by opening the drain valve of the drain path connected to the storage chamber, and the fluid contact chamber as the upper chamber, the separation chamber, and the cleaning drain valve of the cleaning drain path connected to the water supply chamber, The stored sewage and treated water can be transferred to the fluidized stirring chamber. Therefore, all of these sewage and treated water can also flow from the fluidized stirring chamber to the sewer by the return pump.

  Similarly, the water after washing each chamber can also flow into the sewer.

  Therefore, when returning from the self-treatment circulation mode to the water washing mode, when washing each chamber of the sewage treatment means, the work of pumping up the sewage with a vacuum pump and the work of pumping up the water after washing are unnecessary. Workability can be improved.

  In the invention according to claim 9, when the flush mode is used, the flush mode is used in a one-way flow from the water supply to the sewer via the flush mode channel. At this time, the sewage treatment means stores the amount of clean water necessary for the initial operation in the washing mode channel.

  When using the self-treatment circulation mode, the sewage treatment means is circulated and purified using the clean water stored in the flush mode flow path for the initial operation, and water is circulated between the sewage treatment means and the toilet.

  As described above, in the present invention, during normal times when water and sewage is secured, the circulating water purification operation of the sewage treatment means is stopped and used as a water washing mode, so running by reducing power consumption in the sewage treatment means. Cost can be kept low.

  Moreover, since the water stored in the flow channel for the water washing mode can be used for the initial operation of the sewage treatment means when used in the water washing mode, the water for the initial operation is conveyed in an emergency in which water supply or sewerage cannot be secured. Therefore, the sewage treatment means can be immediately circulated and purified and the emergency response is excellent.

  In addition, a predetermined amount of clean water is stored in the flush mode flow path in the flush mode as described above. However, in this flush mode flow path, there is a flow from the water supply to the sewer, so water is stored for a long time. Even if it does, the malfunction which water rots and emits a bad smell does not arise.

The first and second air blowers 36 and 39 are always driven.

  On the other hand, the return pump 37 can be switched between driving and stopping by a water supply chamber upper limit float switch 37 a and a water supply chamber lower limit float switch 37 b provided in the water supply chamber 35. That is, the water supply chamber lower limit float switch 37b is a normally open switch that is turned on when the water level in the water supply chamber 35 falls below the working water level indicated by b in FIG. The water supply chamber upper limit float switch 37a is a normally closed switch that is opened when the water level of the water supply chamber 35 rises above the stop water level indicated by a in the drawing. Accordingly, the return pump 37 starts to drive when the water level in the water supply chamber 35 falls below the working water level b and the water supply chamber lower limit float switch 37b is turned on, and the water level in the water supply chamber 35 rises above the stop water level a and the water supply chamber upper limit. When the float switch 37a is opened, driving is stopped.

  The lift valve 39 e is a valve that drives the air lift 38, and is opened and closed by an air lift operation float switch 32 b provided in the flow stirring chamber 32. The air lift operation float switch 32b is a normally open switch that is turned on when the water level of the flow agitating chamber 32 exceeds the operation water level c. When the air lift operation float switch 32b is turned on, the lift valve 39e is opened and the air lift 38 is opened. Drive.

  The full water display light 40 is switched on / off by a full water float switch 32c provided in the flow stirring chamber 32. The full water float switch 32c is a normally open switch that is turned on when the water level in the flow agitating chamber 32 rises to a preset full water level d, and the full water display light 40 is turned on when the full water float switch 32c is turned on.

  Next, the usage method of the toilet system of Embodiment 1 is demonstrated.

  In the toilet system of the first embodiment, it is possible to use the water washing mode and the self-processing circulation mode in two ways. The water washing mode is a normal usage method in which the water supply 9 and the sewer 5 are secured. On the other hand, the self-processing circulation mode is an emergency usage method in which at least one of the water supply 9 and the sewer 5 cannot be secured, such as at the time of a disaster.

  First, the water washing mode will be described.

  When used in the flush mode, the toilet flushing water switching valve 7, the drainage switching valve 63, and the clean water supply valve 91a as the water flow mode switching means are set to the flush mode. That is, in the toilet flushing water switching valve 7, the first valve 71 is closed and the second valve 72 and the third valve 73 are opened. On the other hand, in the drainage switching valve 63, the circulation side drainage channel 62 is closed and the sewage side drainage channel 61 is opened. Further, the water supply valve 91a is opened.

  Note that the storage chamber drain valve 43a and the sewage discharge valve 42a of the storage chamber 4 are closed.

  Further, the main switch 201 is turned OFF, and all of the return pump 37 and the first and second air blowers 36 and 39 that are driven by electric power are stopped so that no electric power is consumed.

  In the above state, in the toilet system of the first embodiment, the flush mode flow path A shown in FIG. 5 is formed. That is, the flush mode flow path A is a flow path for supplying clean water from the water supply 9 to the toilet 1 and includes a clean water supply path 91, a storage chamber 4, a first overflow path 41, a fluid contact chamber 33, an overflow. The flow path passes through the hole 30 c, the separation chamber 34, the overflow hole 30 d, the water supply chamber 35, the water supply channel 31, and the water tank 2. At this time, as will be described in detail later, the storage chamber 4, the fluid contact chamber 33, the separation chamber 34, and the water supply chamber 35 are filled with tap water supplied in advance from the water supply 9.

  Further, the toilet 1 is connected to the sewer 5 through the sewage-side drainage channel 61 of the drainage channel 6.

  In this flushing mode, after the toilet 1 is excreted, when the washing lever 24b is opened, the flushing water stored in the water tank 2 is caused to flow from the tank drain pipe 22 to the toilet 1 and the excrement is collected together with the flushing water. It flows from the sewer side drainage channel 61 to the sewer 5.

  Further, when the cleaning water is poured in the water tank 2 and the water level is lowered, the float valve 23 is opened, and the water in the water supply chamber 35 is supplied via the water supply channel 31 based on the water head pressure. This supply is stopped when the water tank 2 is full and the float valve 23 is closed.

  On the other hand, when the water level of the water supply chamber 35 is lowered from the full water level e by this supply of water, the water supply float valve 91b is opened, and the water supply of the water supply 9 is supplied to the storage chamber 4 via the water supply channel 91. The Since the storage chamber 4 is filled with water in advance, an overflow occurs with the supplied water through the first overflow path 41, and clean water is supplied to the fluid contact chamber 33.

  Since the fluid contact chamber 33 is also filled with water in advance, overflow is generated by the overflow hole 30c by the supplied water and is supplied to the separation chamber 34. Similarly, from the separation chamber 34 via the overflow hole 30d. It overflows into the water supply room 35.

  When the water level in the water supply chamber 35 rises to the full water level e by repeating such overflow, the water float valve 91b is closed and the supply of clean water to the storage chamber 4 is stopped.

  Thus, every time the water level in the water supply chamber 35 falls from the full water level e using the cleaning water in the water tank 2, clean water is supplied to the storage chamber 4, and the storage chamber 4, the fluid contact chamber 33, and the separation are separated. Overcoming the chamber 34, the water supply chamber 35 is repeatedly returned to the full water level e.

  At the start of use of the toilet system of the first embodiment, when the supply of the clean water to the storage chamber 4 is started by opening the clean water supply valve 91a, the storage chamber 4, the fluid contact chamber 33, and the separation chamber 34 The supply of clean water is stopped when each chamber is filled with water in order and overflows, and finally the water supply chamber 35 reaches the full water level e and the clean water float valve 91b is closed. Chambers 4, 33, 34, and 35 are full of water. At this time, the flow stirring chamber 32 as a lower chamber is empty.

  As described above, in the water washing mode, the toilet 1 is washed and water is supplied without using any electricity, and the running cost is low.

  In addition, the storage chamber 4, the fluid contact chamber 33, the separation chamber 34, and the water supply chamber 35 are always full, but this water repeatedly overflows every time water is supplied. There is no rot due to water flow.

  Next, the operation in the self-processing circulation mode will be described.

  In the event of an emergency, such as a disaster, where the water supply 9 or the sewer 5 cannot be secured, the self-processing circulation mode is switched to use.

  In this case, the maintenance room 200 of the toilet unit TU is entered, and the water supply valve 91a, the drainage switching valve 63, and the toilet flushing water switching valve 7 are switched to the self-processing circulation mode. That is, the water supply valve 91a is closed and the water supply passage 91 is shut off. In the drainage switching valve 63, the circulation side drainage channel 62 is opened and the sewage side drainage channel 61 is closed. Further, the toilet flushing water switching valve 7 opens the first valve 71 and closes the second valve 72 and the third valve 73.

  In the state described above, the toilet system of the first embodiment is formed with the flow path in the self-processing circulation mode shown in FIG.

  Further, the storage chamber drain valve 43a is opened, and the entire amount of water stored in the storage chamber 4 is sent to the flow stirring chamber 32, and then the storage chamber drain valve 43a is closed. The amount of water when the storage chamber 4 is full is set to be equal to or greater than the minimum amount of water required in the fluid agitating chamber 32 when the toilet system of the first embodiment is operated in the self-processing circulation mode. .

  The sewage discharge valve 42a is opened according to the state of the sewage 5 if the sewage 5 is secured, and is closed if the sewage 5 is not secured or the state is not confirmed.

  Thereafter, the main switch 201 is turned on. As a result, the first and second air blowers 36 and 39 start driving, and the return pump 37 and the lift valve 39e (air lift 38) are driven.

  In this way, when aeration is started in the fluid stirring chamber 32 and the fluid contact chamber 33, a deodorant is introduced into both the chambers 32 and 33.

  In this self-treatment circulation mode, water is circulated between the toilet 1 and the sewage treatment means 3 at all times. The circulation path will be described in order based on FIG.

  First, in the toilet bowl 1, the water in the water supply chamber 35 (this water is clean water in the initial stage of use, and then treated water) is always sent via the water supply channel 31 based on the water head pressure. It passes through the drainage channel 62 and falls into the fluidized stirring chamber 32.

  Further, when the water level in the water supply chamber 35 is lowered to the working water level b by water supply to the toilet 1, the water supply chamber lower limit float switch 37 b is turned on, the return pump 37 is driven, and the sewage in the fluid agitating chamber 32 flows into the fluid contact chamber 33. Pumped up.

  By pumping up to the fluid contact chamber 33, the treated water is passed over to the fluid contact chamber 33, the separation chamber 34, and the water feed chamber 35 in the same manner as in the water washing mode, and the water level in the water feed chamber 35 is recovered. When the water level in the water supply chamber 35 rises to the stop water level a, the water supply chamber upper limit float switch 37a is opened, and the drive of the return pump 37 is stopped.

  In this self-processing circulation mode, the above circulation cycle is repeated, and the water in the water supply chamber 35 is always flowed to the toilet 1 based on the water head pressure and drained to the fluidized stirring chamber 32. For this reason, excrement flows immediately, it is hard to produce an odor, and it is hygienic. Moreover, useless water consumption for eliminating the excretion sound does not occur.

  In this self-processing circulation mode, in the fluid agitating chamber 32, filth and toilet paper are crushed and decomposed by aeration by the air diffuser 32a, and deodorization by a deodorant is performed.

  Further, even in the fluid contact chamber 33, the sewage and the air are brought into contact with each other by aeration by the air diffusing tube 33a, and the deodorizing effect is added.

  Further, in the separation chamber 34, the filth settles, and the supernatant water overflows into the water supply chamber 35 as treated water. Therefore, odorless water is supplied to the toilet 1.

  Next, if the use is continued in the self-processing circulation mode, the amount of water in the circulation cycle of the toilet system is increased by adding excrement. In this case, since the storage amount in the processing tank 30 is substantially constant, the water level in the fluidized stirring chamber 32 increases. Therefore, when the water level in the flow stirring chamber 32 rises to the working water level c, the air lift operation float switch 32b is turned on. As a result, the lift valve 39 e is opened, the air lift 38 is driven, and the sediment (sewage) that has settled and separated at the bottom of the separation chamber 34 is sent to the storage chamber 4. The air lift 38 is operated until the water level in the flow stirring chamber 32 falls below the operating water level c and the air lift operation float switch 32b is opened.

  Here, when the sewer 5 is secured, if the sewage discharge valve 42 a is opened, the sewage in the storage chamber 4 passes through the second overflow channel 42 when the storage chamber 4 becomes full. To the sewer 5. Therefore, the sewage treatment means 3 can continue to be used in the self-treatment circulation mode without becoming full.

  On the other hand, when the sewer 5 is not secured, the sewer discharge valve 42a is closed. In this case, when the entire toilet system becomes full and the water level in the flow stirring chamber 32 rises to the full water level d, the full water float switch 32c is turned on and the full water display light 40 is turned on. If the water is full like this, it will be pumped.

  In addition, when performing this pumping, if it is possible to secure water for initial operation at that time by transportation or other means, it is desirable to pump all the water in the toilet system. However, even at this time, when water for initial operation cannot be secured, only the sediment (sewage) pumped from the separation chamber 34 to the storage chamber 4 is pumped, the water amount of the entire system is reduced, and the use is continued. In addition, by removing only the precipitate (sewage) in this way, the degree of water contamination in the toilet system can be suppressed lower than when removing water containing supernatant water.

  When the water supply 9 and the sewer 5 are restored, the rooms 4, 32, 33, 34, and 35 can be washed and used again in the water washing mode.

  In the toilet system according to the first embodiment described above, the water supply mode 9 and the sewerage system 5 can be used in a normal mode when the water supply system 9 and the sewerage system 5 are secured. Compared to doing, running cost can be kept low and it is economical.

  Furthermore, in this flush mode, only the water of the capacity of the water tank 2 is used by one use, and it is the same as a normal flush toilet, and it is not economically inferior compared with a flush toilet.

  On the other hand, in the event of an emergency where the water supply 9 and the sewer 5 cannot be secured, such as during a disaster, the water supply can be used in a self-processing circulation mode that does not require water supply. In this self-processing circulation mode, since water always flows in the toilet bowl 1, it can be comfortably used in a sanitary environment with no odor as in a normal flush toilet.

  Further, when switching from the water washing mode to the self-processing circulation mode, in the maintenance room 200, the storage chamber drain valve 43a opening / closing operation, the drainage switching valve 63 switching operation, the toilet flushing water switching valve 7 switching operation, The operation is simple because only the operation of switching the water supply valve 91a and the operation of turning on the main switch (not shown) are performed.

  Moreover, when switching from the flush mode to the self-processing circulation mode, the water stored in the system in the flush mode is used for initial operation. There is no need to supply water.

  Therefore, unlike the conventional case, there is no need to transport and install a temporary toilet or transport water necessary for the initial operation, and it is possible to immediately perform a circulating water purification operation by the sewage treatment means 3, and in an emergency Excellent compatibility.

  Furthermore, in the first embodiment, the water stored in the fluid contact chamber 33, the separation chamber 34, and the water supply chamber 35 is left as it is, and only the water stored in the storage chamber 4 is dropped into the fluid stirring chamber 32. It simply opens and closes the drain valve 43a, and there is no need to pump it up with a pump or the like, and the workability is excellent.

  Further, in the flush mode channel A in the flush mode, each chamber 4, 33, 34, 35 is always filled with water and is moved by overflow. Even if it is used in the above, there is no problem that the water rots and gives off a bad odor, and there is no problem that the amount of water is insufficient. By the way, when water for use in the self-treatment circulation mode is kept independent and left for a long period of time, there is a problem that the water rots and emits a bad odor, or the water level drops due to evaporation etc. and the amount of water is insufficient. Such a problem does not occur in the toilet system according to the first embodiment.

  In addition, in the first embodiment, the storage chamber 4 is provided with the second overflow path 42 connected to the sewer 5, and when the sewer 5 is secured, the sewage in the storage chamber 4 is caused to flow into the sewer 5, It can be used continuously and is very convenient. In other words, in a normal circulation toilet, when the system is full of water, it is necessary to vacuum the total amount of water, and to supply and store new water necessary for initial operation, which takes time and effort, In the meantime, use becomes unnecessary, but in this embodiment, these problems can be avoided.

  Furthermore, in constructing a toilet system that can be used in two ways, a flush mode and a self-processing circulation mode, the first embodiment uses the existing circulation toilet system, that is, the self-treatment circulation mode. The necessary storage chamber 4, fluid contact chamber 33, separation chamber 34, and water supply chamber 35 are arranged at such a height that water can be supplied to the toilet 1 and water tank 2 with water head pressure, and the drainage switching valve 63 and the toilet flushing water switching valve 7. The water supply path 91 and the water supply valve 91a, the drain path 43 and the storage chamber drain valve 43a, the second overflow path 42 and the sewage discharge valve 42a can be configured simply by adding and are necessary for the installation. Space can be made compact, manufacturing costs can be kept low, and versatility is excellent.
