JP 2006-016958 A

  As mentioned above, a pressure-feed toilet device is a pipe that is connected to the sewage on the downstream side, such as a rising pipe or a pipe with high internal pressure loss. Even if there is, it has a certain pumping capacity. However, in those pipes where sewage and filth contained in sewage are difficult to flow, for example, when the stirring means or pumping means cannot be operated due to a failure or power failure, the sewage and sewage contained in the sewage are removed from the drain pipe. There is a risk that it will not flow downstream. At that time, in the flow path opening / closing valve that supplies water to the toilet body, water is often supplied to the toilet body due to poor water stoppage due to the biting of foreign matter. In this case, water may overflow (overflow) from the toilet body to the toilet space where the toilet body is installed. When the toilet body overflows into the toilet space, there is a problem that sewage and filth contained in the sewage contaminate the area around the installation site of the pressure-feed toilet device, and sanitary properties are impaired.

  Therefore, the present invention has been made to solve the above-described problem, and prevents water supply from being performed when at least one of the stirring means and the pressure feeding means of the pressure-feed toilet apparatus is inoperable. An object of the present invention is to provide a pressure-fed toilet device capable of preventing overflow from the toilet body to the toilet space.

  A pressure-fed toilet device according to the present invention is a pressure-fed toilet device that stirs filth contained in sewage discharged from a toilet body and pumps it together with the sewage to a downstream drain pipe, and is a flush water to the toilet body.

Insufficient water stoppage in the valve can be prevented. Therefore, the drainage pipe leading to the sewage downstream of the pressure-fitted toilet device is a pipe that may cause sewage and filth contained in the sewage to flow unless the stirring means and the pressure-feeding means described above operate, and Even if at least one of the stirring means and the pressure feeding means cannot operate, water supply due to poor water stoppage of the flow path opening / closing valve is not performed. As a result, it is possible to prevent overflow from the toilet body, and to ensure the hygiene of the place where the pressure-fitted toilet device is installed.

  Further, in the pressure-feed toilet apparatus according to the present invention, the solenoid valve that is controlled by the control unit and opens and closes the water supply path for supplying the wash water to the toilet body, and the stirring means and the pressure-feed means are inoperable. And when the abnormality detection means detects that at least one of the stirring means and the pressure feeding means is inoperable, the control unit closes the water supply path with respect to the electromagnetic valve. This is a pressure-feed type toilet device that outputs a control signal.

  In the present invention configured as described above, an electromagnetic valve that opens and closes a water supply path for supplying cleaning water to the toilet body is provided, and the control unit is configured to operate when at least one of the stirring means and the pressure feeding means is inoperable Controls so that the solenoid valve does not supply water. Thereby, for example, even when at least one of the stirring means and the pressure feeding means cannot be operated due to a failure or a power failure, and the flow path opening / closing valve can be opened, water supply is not performed. Therefore, when the stirring means and the pressure feeding means cannot be operated, water supply is not performed, and overflow from the toilet body can be prevented more reliably.

Hereinafter, a pressure-feed toilet apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic configuration diagram showing a pressure-feed toilet apparatus according to an embodiment of the present invention. As shown in FIG. 1, in the present embodiment, a pressure-fed toilet device 1 includes a toilet body 2, a float valve 4 (flow path opening / closing valve) that starts or stops the supply of cleaning water to the toilet body 2, and a toilet body 2 includes a pumping device 8 that stirs filth contained in the sewage discharged from 2 and pumps the sewage together with the sewage to the downstream drainage pipe 6 that communicates with the sewage, and a controller 9 that controls the operation of the pumping device 8.

  The float valve 4 is provided inside a low tank 10 that stores wash water supplied from a water supply source (not shown), and supplies the wash water to the toilet body 2 via the wash water supply unit 12 by performing an opening operation. . The flow path opening / closing valve may be an electromagnetic valve that is electrically opened / closed instead of the float valve.

  The opening / closing operation of the float valve 4 is performed by a water supply operation detecting means (not shown) for detecting a water supply operation to the toilet body 2 and a cleaning operation detecting means (not shown) for detecting a cleaning operation to the toilet body 2. As a water supply operation detection means (not shown) and a washing operation detection means (not shown), a lever provided in the low tank 10, a switch on an operation panel of a remote controller installed in the room, or the like is used.

  A strainer 14 is provided on the upstream side of the float valve 4 to remove foreign substances contained in the cleaning water. Further, an electromagnetic valve 16 that opens and closes the water supply path 15 is provided downstream of the strainer 14 and upstream of the float valve 4. The solenoid valve 16 is a normally closed solenoid valve that is electrically opened and closed, opens when energized, and maintains a closed state when de-energized.

  The pumping device 8 has a storage tank 20 that communicates with the discharge port 18 of the toilet body 2 and stores sewage discharged from the discharge port 18 and filth 19 contained in the sewage and toilet paper. Inside the storage tank 20, there is a pulsator 22 (stirring means) that makes it easy to stir and flow the sewage 19 contained in the sewage by the action of stirring the sewage by a rotary motion, and the sewage 19 that is easily swept away. And an impeller 24 (pressure feeding means) for pressure-feeding to the drain pipe 6 communicating with the sewage by rotational movement. An impeller 24 is provided at the lower end of the rotating shaft 26 of the pulsator 22, and a motor 28 for rotating the rotating shaft 26 is attached to the upper end.

  A water level sensor 30 (water level detection means) that detects the water level inside the storage tank 20 is attached to the storage tank 20. The water level sensor 30 includes a pressure guiding pipe 30a that is suspended from the upper side toward the lower side in the storage tank 20, and a pressure sensing unit 30b that is attached to the upper end of the pressure guiding pipe 30a and is made of a diaphragm or the like. Since the lower end portion of the pressure guiding tube 30a is opened, a pressure corresponding to the water pressure is applied to the air inside the pressure guiding tube 30a by being submerged in water. By detecting the water pressure by the pressure sensing unit 30b via the pressure on the air, it becomes possible to detect the water level corresponding to the water pressure.

  Furthermore, the pressure-feed toilet apparatus 1 according to the present embodiment includes an abnormality detection unit 31 that detects an abnormality such as a failure in the pulsator 22 and the impeller 24. The abnormality detection means 31 is composed of a Hall IC or the like, and is a rotation speed sensor that detects the rotation speed of the motor 28, or detects the current and voltage of the motor 28 and determines the operation status of the motor 28 depending on the detected value. A detection device or the like for determination is used.

  The opening and closing of the electromagnetic valve 16 is controlled by a control unit 9 that controls the operation of the pressure feeding device 8. Further, the rotation speed and rotation time of the motor 28 are controlled by the control unit 9. Further, the control unit 9 operates the pump-type toilet device 1 for the user based on the water level detected by the water level sensor 30 and the abnormality in the pulsator 22 and the impeller 24 detected by the abnormality detection means 31. An informing means 32 for informing the situation is connected. The notification means 32 includes an LED lamp, a buzzer that emits an alarm sound, and the like.

Next, with reference to FIG. 2, the functional structure of the control part of the pressure-feed type toilet apparatus in one Embodiment of this invention is demonstrated. FIG. 2 is a block diagram illustrating a control configuration of the pressure-fed toilet apparatus according to the embodiment of the present invention.
As shown in FIG. 2, the control unit 9 includes a water level sensor 30, an abnormality detection unit 31, a human body detection sensor 34 that detects the seating and approach of the human body to the toilet body 2, and the start and stop of water supply to the toilet body 2. The water supply operation detecting means 36 for detecting the above, the electromagnetic valve 16, the motor 28, and the notifying means 32 are electrically connected. The control unit 9 includes a microcomputer (not shown). Based on output signals from the sensors and detection means, the control unit 9 opens and closes the electromagnetic valve 16 and rotates the rotation speed and rotation time of the motor 28 according to a program stored in advance. And the control of the alerting | reporting means 32 is performed.

  In addition, when the control unit 9 detects that the motor 28 is inoperable, that is, the pulsator 22 and the impeller 24 are inoperable, by the abnormality detection unit 31, the control unit 9 opens the water supply path 15 to the electromagnetic valve 16. Output control signal to close. At the same time, the notification means 32 notifies that the pulsator 22 and the impeller 24 are inoperable.

Hereinafter, with reference to FIG. 3, the cleaning operation of the pressure-feed toilet apparatus in the present embodiment will be described. FIG. 3 is a flowchart showing the cleaning operation in the present embodiment.
First, when the power supply of the pressure-fitting toilet apparatus 1 is turned on (step S101), the control unit 9 causes the electromagnetic valve 16 to perform an opening operation so that the cleaning water supplied from a water supply source (not shown) It is stored in the low tank 10 through the strainer 14 that removes (step S103). In this case, the toilet body 2 is not supplied with water and is not stored. The control unit 9 determines whether or not the time T1 has elapsed from the opening operation of the electromagnetic valve 16 (step S105), and when it has elapsed, the electromagnetic valve 16 is closed (step S107). Continue to supply cleaning water to store water inside.

  When the storage of the wash water in the low tank 10 is completed, the pressure-feed toilet apparatus 1 enters the standby mode (step S109). If the power is turned off at this time, the pressure-fed toilet apparatus 1 ends the operation.

  Subsequently, it is detected by the human body detection sensor 34 (not shown) that the user is seated or approached, or an operation for supplying water to the toilet body 2 by the user is performed by a water supply operation detecting means (not shown). When detected (step S111), the float valve 4 is opened (step S113). Thereby, water is supplied from the low tank 10 through the washing water supply unit 12 so as to collect water in the toilet body 2. The control unit 9 detects the start of water supply by the opening operation of the float valve 4 by the water supply operation detecting means 36, and determines whether or not the time T3 has elapsed from the start (step S115). If the time T3 has elapsed, the float valve 4 is closed (step 117), and the pressure-fed toilet device 1 is ready for use. When the time T3 has not elapsed, the water supply for storing water to the toilet body 2 is continued until the time T3 has elapsed.

  Next, after the user's excretion, it is determined that the human body detection sensor 34 performs the separation determination and the toilet body 2 can be automatically washed (for example, after a predetermined time has elapsed since the separation), or the user When the operation for cleaning the toilet main body 2 is detected by a cleaning operation detection means (not shown) (step S119), the float valve 4 is opened (step S121). Accordingly, the wash water stored in the low tank 10 is supplied to the toilet body 2 via the wash water supply unit 12. By supplying the cleaning water, the sewage and the filth 19 contained in the sewage are discharged from the outlet 18 of the toilet body 2 to the storage tank 20 of the pressure feeding device 8.

  The controller 9 detects the start of water supply by the opening operation of the float valve 4 by the water supply operation detecting means 36, and determines whether or not the time T5 has elapsed from the start (step S123). When T5 has elapsed, voltage starts to be applied to the motor 28 that rotates the pulsator 22 and the impeller 24 (step S125), the filth 19 is agitated, and the agitated filth 19 and sewage are discharged to the drain pipe 6. Pumping is started. On the other hand, when the time T5 has not elapsed, the supply of flush water to the toilet body 2 is continued without stirring and pumping until the time T5 has elapsed.

  Next, the control unit 9 determines whether or not the time T7 has elapsed from the start of voltage application to the motor 28 (step S127). If the time T7 has elapsed, the float valve 4 is closed (step S129). On the other hand, when the time T7 has not elapsed, the stirring and pumping and the supply of the washing water to the toilet body 2 are continued until the time T7 has elapsed.

  Subsequently, the control unit 9 determines whether or not the time T9 (greater than the time T7) has elapsed since the start of voltage application to the motor 28 (step S131). When the time T9 has elapsed, the application of voltage to the motor 28 is stopped, and the stirring and pumping are stopped (step S133). On the other hand, when time T9 has not passed, stirring and pressure feeding are continued.

  After stopping the application of the voltage to the motor 28, the control part 9 opens the electromagnetic valve 16, and stores wash water in the low tank 10 (step S103). Further, the control unit 9 determines whether or not the time T1 has elapsed from the opening operation of the electromagnetic valve 16 (step S105), and if it has elapsed, closes the electromagnetic valve 16 (step S107). If not, the washing water is continuously stored in the low tank 10. After the solenoid valve 16 is closed, the mode again shifts to the standby mode.

  When cleaning water supplied from a water supply source (not shown) is stored in the raw tank 10 (step S103), storage is performed via a strainer 14 that removes foreign substances contained in the cleaning water from the cleaning water. Thereby, since the foreign substance is not contained in the washing water stored in the low tank 10, in the subsequent control steps, the float valve 4 does not bite the foreign substance, and the float valve 4 caused by this does not bite. It can prevent poor water stoppage. Therefore, even when at least one of the pulsator 22 and the impeller 24 is inoperable due to a failure, a power failure, or the like, water supply due to poor water stoppage is not performed. Since the water supply is not performed, even if the drain pipe 6 is a pipe that may not allow the sewage and the filth 16 to flow unless the pulsator 22 and the impeller 24 are operated, the overflow from the toilet body 2 can be prevented. it can.

  Subsequently, an operation at the time of abnormality determination of the stirring unit and the pressure feeding unit in the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing the abnormality determination operation in the present embodiment. This abnormality determination operation is performed immediately after the opening of the solenoid valve 16 by the control unit 9 or immediately after the end of the cleaning operation, or when the human body detection sensor 34 detects a long-term separation of the user. Done. Moreover, in order to prevent the overflow from the toilet body 2 more reliably, an abnormality determination operation may be performed automatically on a regular basis.

  First, when an abnormality determination operation is started (step S201), the abnormality detection unit 31 detects an abnormality in the motor 28, that is, the pulsator 22 and the impeller 24. Here, the control unit 9 determines whether or not the abnormality detection unit 31 has detected an abnormality in the motor 28 (step S203). If an abnormality is detected, the solenoid valve 16 is closed (step S205). Further, after the solenoid valve 16 is closed, the notification means 32 notifies the abnormality of the motor 28 (step S207), and the abnormality determination operation is completed (step S209). On the other hand, if the abnormality detection means 31 does not detect the abnormality of the motor 28, the abnormality determination operation is completed immediately after that (step S209).

  When performing the abnormality determination operation, if the motor 28, that is, the pulsator 22 and the impeller 24 cannot be operated, the electromagnetic valve 16 provided on the upstream side of the float valve 4 closes the water supply path 15 (step S205). ). Therefore, even when the pulsator 22 and the impeller 24 are inoperable and the float valve 4 can be opened, water supply is not performed. Therefore, overflow from the toilet body 2 can be reliably prevented.

  Since the solenoid valve 16 is a normally closed solenoid valve, the water supply path 15 is always closed when the solenoid valve 16 cannot be electrically operated due to a power failure or disconnection. Therefore, even if the electromagnetic valve 16 cannot be operated due to a power failure or disconnection, water supply to the toilet body 2 is not performed, and overflow from the toilet body 2 can be reliably prevented.
