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, if the rising pipe leads to a higher place than the toilet body, or if the pressure loss in the pipe is too high, the drainage of the pressure-feed toilet device may not flow downstream. is there. As a result, the sewage that cannot be pumped and the filth contained in the sewage flow backward, not only preventing the pumping during the subsequent pumping, but also noticing that the drain pipe is a pipe that cannot be pumped downstream. If water supply continues to be performed without water, there is a possibility that water overflows (overflows) from the toilet body to the toilet space. When the toilet body overflows, there is a problem that sewage and filth contained in the sewage contaminate the surroundings of the place where the pressure-fitted toilet apparatus is installed, and sanitary property is impaired.

  Therefore, the present invention has been made to solve the above-described problems, and when the drain pipe on the downstream side of the pressure-feed toilet device is a pipe that cannot pump sewage and filth contained in the sewage, An object of the present invention is to provide a pressure-fed toilet device capable of notifying the user and preventing overflow from the toilet body to the toilet space.

  The pressure-fed toilet device according to the present invention is a pressure-fed toilet device that stirs filth contained in sewage discharged from the toilet body and pumps it together with the sewage to a downstream drainage pipe, and includes flush water for the toilet body. Water supply means for starting or stopping the supply of water, a sewage discharged from the toilet body and a storage tank for storing the filth contained in the sewage, an agitation means for stirring the filth inside the storage tank, and stirred by the agitation means A control unit that controls the operation of the pumping device, and a control unit that controls the operation of the pumping device, and a control unit that controls an operation of the pumping device. And a notification unit that performs notification based on a command from the unit, and the control unit detects the water level detected by the water level detection unit when a predetermined time has elapsed after the stirring unit and the pressure feeding unit start operation. Pre-decision By determining whether or not the water level is equal to or higher than the predetermined water level, control is performed to perform a drain pipe determination operation to determine whether or not the drain pipe is a pipe capable of pumping sewage and agitated filth. In operation, when it is determined that the water level detected by the water level detection means is equal to or higher than a predetermined water level determined in advance, the supply of cleaning water by the water supply valve and the operation of the stirring means and the pressure feeding means are prohibited, and the drain pipe is sewage And it is the pressure-feed type toilet apparatus characterized by performing the control which alert | reports by a notification means that it is piping which cannot pump pressure the stirred filth.

  In the present invention configured as described above, when the predetermined time has elapsed from the start of the operation of the agitating means and the pressure feeding means, the control unit detects sewage and agitation if the water level detecting means detects a water level above a predetermined level. Pipes that judge that the filth is not discharged from the pumping device and prohibit the supply of cleaning water by the water supply valve and the operation of the stirring means and the pumping means, and the drain pipe cannot pump the sewage and the stirred filth downstream Notify that. Therefore, when the drain pipe cannot sufficiently pump sewage and agitated filth by pumping, the user can know it and water supply is not performed, and overflow from the toilet body can be prevented. . As a result, it becomes possible to ensure the hygiene of the place where the pressure-feed toilet apparatus is installed.

  Further, in the pressure-fed toilet device according to the present invention, the control unit cleans the toilet body with the cleaning water supplied by the water supply valve, and stores the wastewater generated by the cleaning and the filth contained in the wastewater in the storage tank. The waste water is agitated by the agitation means, and is pumped to the drain pipe by the pressure feeding means, and the washing water is discharged from the toilet main body by supplying water for a predetermined time by the washing operation mode in which normal washing is performed and the water supply valve. After storing the water in the storage tank and operating the stirring means and the pressure feeding means for a predetermined time, the drain pipe judgment operation is performed to determine whether the drain pipe is a pipe capable of pumping the sewage and the stirred filth. The operation of the stirring means and the pressure feeding means in the trial operation mode is performed at a lower speed than the operation of the stirring means and the pressure feeding means in the cleaning operation mode.

Moreover, the human body detection sensor 34 which detects a user's seating or approach to the toilet body 2 may be connected.

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 CPU 90, a timer 92, a memory 94 (storage means), an operation reception unit 900 as an interface, a water level detection unit 902, an abnormality detection unit 904, a human body detection unit 906, A drain valve drive unit 908, an electromagnetic valve drive unit 909, a motor drive unit 910, and a notification execution unit 912 are included.

The water level detection unit 902 is a part that outputs a water level signal output from the water level sensor 30 to the CPU 90. The abnormality detection unit 904 is a part that outputs an abnormality detection signal output from the abnormality detection means 31 to the CPU 90. The human body detection unit 906 is a part that outputs a human body detection signal output from the human body detection sensor 34 to the CPU 90.

  The drain valve driving unit 908 and the electromagnetic valve driving unit 909 are parts for outputting a valve driving signal to the drain valve 4 and the electromagnetic valve 16 based on a control signal output from the CPU 90. The motor drive unit 910 is a part that outputs a motor drive signal such as a rotation speed and a rotation time to the motor 28 that rotates the pulsator 22 and the impeller 24 based on a control signal output from the CPU 90. The notification execution unit 912 is a part that outputs a notification execution signal for performing abnormality notification or driving notification to the notification means 32 based on a control signal output from the CPU 90.

  The CPU 90 receives signals output from the operation reception unit 900, the water level detection unit 902, the abnormality detection unit 904, and the human body detection unit 906, performs predetermined information processing, and responds to control executed as a result of the information processing. The control signal is output to each of the drain valve drive unit 908, the electromagnetic valve drive unit 909, the motor drive unit 910, and the notification execution unit 912. As a result, the CPU 90 performs drainage pipe determination operation execution means, drainage pipe determination means, operation mode selection means, cleaning operation mode execution means, trial operation mode execution means, water level determination means, abnormality determination means, valve drive time determination means, motor drive. Functions as time determination means. The control unit 9 configured as described above enables the pressure-fed toilet device 1 to perform various controls in accordance with the characteristics of the usage situation and the characteristics of the user.

  The control unit 9 includes motor drive time determination means for determining whether or not a predetermined time has elapsed since the motor drive unit 910 started operating the motor 28, that is, the pulsator 22 and the impeller 24, based on information from the timer 92. Water level determination means for determining whether the water level detected by the water level sensor 30 is equal to or higher than a predetermined level. Further, when the motor drive time determination unit determines that a predetermined time has elapsed from the start of the operation of the motor 28, the control unit 9 allows the drain pipe 6 to pump sewage and agitated waste 19 by the water level determination unit. And a drain pipe determination operation executing means for executing a drain pipe determination operation for determining whether or not.

  In this drain pipe determination operation, when the water level determination means determines that the water level is equal to or higher than a predetermined level, the memory 9 performs a process of prohibiting the supply of cleaning water by the water supply valve 4 and the operation of the pulsator 22 and the impeller 24. (Push the non-pumpable piping flag on). At the same time, the notification means 32 notifies that the drain pipe 6 is a pipe that cannot pump the sewage and the stirred filth 19. In addition, the control part 9 has a drain pipe determination means, and whether the drain pipe 6 is a pipe that can be pumped from the information (pumping impossible pipe flag) stored in the memory 94 by the drain pipe determination means. Determine whether or not.

  Moreover, the control part 9 is based on the output signal from the timer 92, the water supply operation detection means 11, the washing operation detection means 12, or the human body detection sensor 34, and two different operation modes (washing operation mode and trial operation mode) mentioned later. The operation mode selection means for selecting and executing one of them. When the operation mode is selected by the operation mode selection means, the control unit 9 executes the selected operation mode by the execution means (cleaning operation mode execution means and trial operation mode execution means).

  Furthermore, the control unit 9 includes an abnormality determination unit that determines whether there is an abnormality such as a failure in the pulsator 22 and the impeller 24 based on an abnormality detection signal from the abnormality detection unit 904, and a water supply valve drive unit 908. Water supply valve drive time determination means for determining whether or not a predetermined time has elapsed since the operation of the water supply valve 4 is started based on information from the timer 92.

Hereinafter, the two control modes executed by the control unit in the present embodiment will be described with reference to FIGS. 3 and 4. First, the cleaning operation mode will be described with reference to FIG. 3 which is a flowchart showing a normal cleaning operation mode in the present embodiment.
As shown in FIG. 3, when the cleaning operation mode is selected by the operation mode selection means, the cleaning operation mode is started by the cleaning operation mode execution means (step S101), and the user is seated or approached by the human body detection sensor 34. When the water supply start operation by the user is detected by the water supply operation detection means 11 (step S111), the control unit 9 turns on the non-pumpable piping flag F stored in the memory 94. It is determined whether or not (step S112).

  When the non-pumpable piping flag F is off, that is, when the drain pipe 6 determines that the sewage and the stirred filth 19 are not nonpumpable pipes (step S112: NO), the water supply valve 4 is An opening operation is performed (step S113). As a result, wash water is supplied from the low tank 10 through the drain valve 4 to collect water in the toilet body 2. At this time, at the same time, the controller 9 opens the electromagnetic valve 16 only for the time T4. Since the ball tap 17 operates in accordance with a drop in the water level inside the low tank 10, the wash water is stored inside the low tank 10 via the electromagnetic valve 16.

  The controller 9 determines whether or not the time T3 has elapsed since the start of the opening operation of the drain valve 4 for storing water (step S115). If the time T3 has elapsed, the drain valve 4 is closed (step 117), and the pressure-fed toilet apparatus 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 is separated from the seat and the toilet body 2 can be automatically washed (for example, after a predetermined time has elapsed since leaving), or by the user. When the cleaning operation detecting unit 12 detects the cleaning start operation of the toilet body 2 (step S119), the drain valve 4 is opened (step S121). Thereby, the wash water stored in the low tank 10 is supplied to the toilet body 2 via the drain valve 4. 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. At this time, at the same time, the control unit 9 opens the electromagnetic valve 16 only for the time T6. Since the ball tap 17 operates in accordance with a drop in the water level inside the low tank 10, the wash water is stored inside the low tank 10 via the electromagnetic valve 16.

  The controller 9 determines whether or not the time T5 has elapsed from the start of the opening operation of the drain valve 4 for cleaning (step S123). When the time T5 has elapsed, the voltage V0 starts to be applied to the motor 28 that rotates the pulsator 22 and the impeller 24 (step S125), the filth 19 is stirred, and the drainage pipe 6 of the filth 19 and the sewage that has been stirred is stirred. The pumping to is started. On the other hand, when the time T5 has not elapsed, the drain valve 4 is kept open and the supply of the washing 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 drain 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). If the time T9 has elapsed, the water level sensor 30 detects the water level W inside the storage tank 20 (step S133), and whether or not the drain pipe 6 is a pipe capable of pumping sewage and the stirred filth 19. The drain pipe judging operation for judging In step S112, when the non-pumpable piping flag F is turned on, that is, when the drain pipe 6 determines that the sewage and the stirred filth 19 are nonpumpable pipes (step S112: YES). ) Similarly, the water level W inside the storage tank 20 is detected by the water level sensor 30 (step S133), and the drain pipe determination operation is started.

  Next, the controller 9 determines whether or not the water level W is higher than the predetermined water level W1 (step S137). When the water level W is lower than the predetermined water level W1 (step S137: YES), the pumping impossible piping flag F is set to OFF (step S139). When the water level W is higher than the predetermined water level W1 (step S137: NO), the pressure non-feedable piping flag F is set to ON (step S141), and the drain pipe 6 cannot pump sewage and the stirred filth 19 It is notified by the notification means 32 that it is a simple pipe (step S143).

  Subsequently, it is determined whether or not a voltage is applied to the motor 28 regardless of the height of the water level W (step S145). If not applied, the cleaning operation mode is terminated (step S149). When the voltage is applied, the voltage application to the motor 28 is stopped to stop the stirring and the pressure feeding (step S147), and then the cleaning operation mode is ended (step S149).

  When the predetermined time T9 has elapsed from the start of operation of the pulsator 22 and the impeller 24, the control unit 9 detects the water level W and starts the drain pipe determination operation (step S133). When the water level W is higher than the predetermined water level W1, it is determined that the sewage and the stirred filth 19 have not been discharged from the pressure feeding device 8, and the supply of the cleaning water by the drain valve 4 and the operation of the pulsator 22 and the impeller 24 are not performed thereafter. (Step S112). Further, the notification means 32 notifies that the drain pipe 6 is a pipe that cannot pump the sewage and the stirred filth 19 downstream (step S143). Therefore, in the case where the drain pipe 6 cannot sufficiently pump the sewage and the stirred filth 19 by pumping, the user can know it and water supply is not performed, and overflow from the toilet body 2 is prevented. be able to.

Next, the test operation mode will be described with reference to FIG. 4 which is a flowchart showing the test operation mode in the present embodiment. This trial operation mode is used immediately after installing the pressure-feed toilet apparatus 1 or when the power-feed toilet apparatus 1 is turned on, or when the human body detection sensor 34 detects a long-term separation of the user. Selected by the operation mode selection means and executed by the trial operation mode execution means. 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.
When the trial operation mode is started (step S301), the control unit 9 determines whether or not the non-pumpable piping flag F stored in the memory 94 is turned on (step S312).

  When the non-pumpable piping flag F is turned off, that is, when the drain pipe 6 determines that the sewage and the stirred filth 19 are not pipes that cannot be pumped (step S312: NO), the drain valve 4 is An opening operation is performed (step S313). As a result, wash water is supplied from the low tank 10 through the drain valve 4 to collect water in the toilet body 2 and the storage tank 20. At this time, at the same time, the controller 9 opens the electromagnetic valve 16 only for a time T8. Since the ball tap 17 operates in accordance with a drop in the water level inside the low tank 10, the wash water is stored inside the low tank 10 via the electromagnetic valve 16.

  The controller 9 determines whether or not the time T1 has elapsed from the start of the opening operation of the drain valve 4 (step S315). If the time T1 has elapsed, the drain valve 4 is closed (step 317). When the time T1 has not elapsed, the water supply for storing water to the toilet body 2 and the storage 20 is continued until the time T1 has elapsed.

  Subsequently, the voltage V1 starts to be applied to the motor 28 that rotates the pulsator 22 and the impeller 24 (step S325), and the pumping of the washing water to the drain pipe 6 is started. The voltage V1 applied here is a voltage smaller than the voltage V0 applied to the motor 28 in the above-described cleaning operation mode. Therefore, the motor 28 rotates the pulsator 22 and the impeller 24 at a lower speed than in the above-described cleaning operation mode.

  Next, the control unit 9 determines whether or not the time T2 has elapsed from the start of voltage application to the motor 28 (step S327). If the time T2 has elapsed, the water level W inside the storage tank 20 is detected by the water level sensor 30 (step S333), and whether the drain pipe 6 is a pipe capable of pumping sewage and stirred filth 19 or not. The drain pipe judging operation for judging In step S312, when the non-pumpable piping flag F is turned on, that is, when the drain pipe 6 determines that the sewage and the stirred filth 19 are nonpumpable pipes (step S312: YES). ) Similarly, the water level W inside the storage tank 20 is detected by the water level sensor 30 (step S133), and the drain pipe determination operation is started.

  Next, the controller 9 determines whether or not the water level W is higher than the predetermined water level W1 (step S337). When the water level W is lower than the predetermined water level W1 (step S337: YES), the pumping impossible piping flag F is set to OFF (step S339). When the water level W is higher than the predetermined water level W1 (step S337: NO), the pressure non-pumpable piping flag F is set to ON (step S341), and the drain pipe 6 cannot pump the sewage and the stirred filth 19 It is notified by the notification means 32 that it is a simple pipe (step S343).

  Subsequently, it is determined whether or not a voltage is applied to the motor 28 regardless of the height of the water level W (step S345). If not applied, the test operation mode is terminated (step S349). When the voltage is applied, the voltage application to the motor 28 is stopped to stop the stirring and the pressure feeding (step S347), and then the test operation mode is ended (step S349).

  When pumping cleaning water in the trial operation mode, the applied voltage to the motor 28 is set to V1, which is a voltage smaller than the applied voltage V0 in the above-described cleaning operation mode (step S325). That is, the operations of the pulsator 22 and the impeller 24 are executed at a lower speed than in the cleaning operation mode. As a result, the trial operation mode is performed in a state where the stirring and pumping capabilities are reduced. Therefore, when performing the drain pipe determination operation, it is determined that only the drain pipe that can be pumped more reliably is the pipe that can be pumped. Is done. Therefore, the safety | security with respect to the overflow from a toilet bowl main body can further be improved.
