FIG. 7 is a block diagram for explaining the system outline of the flush toilet unit according to the present invention.

First, based on FIG. 1 thru | or FIG. 3, the structure of the flush toilet unit which concerns on this invention is demonstrated. As shown in FIGS. 1 to 3, a flush toilet unit 100 includes, in a housing 1, a toilet 20, a low tank 2 for storing wash water to be passed to the toilet 20, and sewage purification for purifying used wash water. Part (sewage purification means) 30.
Further, the sewage purification unit 30 stores the sewage and the wash water from the toilet 20 through the drain pipe 23 that is a drainage channel, and the circulating water that has been promoted for oxidation in the basin 5 for purification. A pumping tank 6. Furthermore, it has the separation tank 7 and the sedimentation tank 8 which isolate | separate each suspended matter from the circulating water pumped up from the pumping tank 6 by pumping, and the water tank 9 which stores the purified wash water.

  Further, the washing water purified by the sewage purification unit 30 is supplied to the raw tank 2 through the water supply pipe 10, and the washing water stored in the raw tank 2 is passed through the water supply pipe 3 when necessary. 20 is supplied.

  In addition, the wash water supplied to the toilet bowl 20 is flowed to the water tank 5 of the sewage purification unit 30 through the drain pipe 23, and the overflow pipe 4 is connected to the toilet bowl 20 as shown in FIG. That is, when the flush water accumulates in the toilet bowl 20 due to the clogging of the drain pipe 23, the accumulated wash water flows into the water tank 5 through the overflow pipe 4.

  Further, a flow rate sensor 11 (flow rate detection means) is provided on the overflow pipe 4 as shown in FIG. This flow sensor 11 detects the flow rate of the washing water in the overflow pipe 4 and outputs a detection signal when a water amount of a predetermined amount or more is detected. The situation where the wash water flows into the overflow pipe 4 is a case where the wash water is accumulated in the toilet 20 more than necessary due to the clogging of the drain pipe 23. Therefore, it is possible to determine whether the drainage pipe 23 is clogged based on the detection signal.

  Next, the toilet 20 will be described with reference to FIGS. As shown in the figure, the toilet 20 includes a toilet body 21. As shown in FIG. 5, the toilet body 21 is formed with a drain port 21a, and as shown in FIGS. 4 and 6, a drain pipe 23 is connected to the drain port 21a.

  First, as shown in FIGS. 7A and 7B, during normal operation, the filth in the toilet 20 is caused to flow into the water tank 5 by the wash water supplied from the low tank 2. In this water tank 5, the wash water that has become sewage starts to oxidize by the action of microorganisms and the like while being fluidly stirred. That is, the wash water, which is dirty water, is sterilized by an oxidizing action, and malodorous components are decomposed. In the pumped water layer 6, large foreign matters are removed and the pump 12 pumps the water into the separation tank 7. In the separation tank 7, the suspended matter in the wash water is separated by rotation, and the suspended matter in a diffused state aggregates and precipitates. Further, in the sedimentation tank 8, the suspended matter is similarly rotated and separated, and the cleaning water is further purified. The cleaning water purified in this way is stored in the water tank 9 and further supplied to the raw tank 2.

  If the drain pipe 23 is filled with vinyl or the like due to mischief or the like of the toilet user, the wash water that has flowed to the toilet main body 21 does not flow through the drain pipe 23 and therefore accumulates in the toilet main body 21. When the washing water is accumulated up to the height of the drain hole 22, the washing water flows into the overflow pipe 4 without overflowing the toilet body 21. Here, the flow sensor 11 detects the flow of cleaning water in the overflow pipe 4 and outputs a detection signal to the control means 13.

Here, in the case of FIG. 7A, the control means 13 outputs an operation stop command to the pump 12, and the pump 12 stops operating (or all power sources related to the circulating operation of the washing water may be stopped. ). That is, the wash water does not circulate when the pump 12 stops operating.
On the other hand, in the case of FIG. 7B, the control means 13 controls the operation so as to close the valve 14 provided on the water supply pipe 10 between the water tank 9 and the raw tank 2. That is, the wash water is not supplied to the low tank 2 and the circulation operation of the wash water is stopped.
As described above, in any of the cases shown in FIGS. 7A and 7B, since no new wash water is supplied to the raw tank 2, the wash water is not allowed to flow into the toilet bowl 20, and is thus out of the toilet bowl. The overflow of water can be prevented.

  A message means (not shown) for automatically displaying a message such as “failing” or “discontinued use” on the outer wall surface of the housing 1 by means of an electric display or the like in synchronization with a detection signal from the flow sensor 11. Is preferably provided. In this way, the user can be notified in advance.

According to the embodiment described above, even when the drain pipe 23 is clogged due to mischief or the like, the wash water can be drained by the overflow pipe 4. In addition, the clogging of the drain pipe 23 can be detected by providing the flow rate sensor 11 in the overflow pipe 4, and the circulation operation of the washing water can be controlled by the control means 13. Therefore, when the drain pipe 23 is clogged, no new washing water is supplied to the low tank 2, so that no washing water flows into the toilet bowl 20, and it is possible to completely prevent water overflow from the toilet bowl 20. it can.
Further, by providing the message means, it is possible to inform the user in advance that a failure is occurring.

The configuration of the sewage purification unit 30 shown in the above embodiment is an example of a configuration that purifies and circulates sewage, and is not limited to this, and is another configuration as long as it is a configuration that purifies and circulates sewage. Also good.
Moreover, in the said embodiment, although the shape of the toilet bowl 20 was made into the shape of a Japanese style toilet bowl, the shape of a western style toilet bowl (or the shape of a urinal) may be sufficient, and the draining means is formed in the toilet bowl main body. May be.
