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 processing for prohibiting the supply of cleaning water by the drain 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).

Further, 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. yo Ri drain valve 4 operates to start having a water supply valve drive time determination means for determining based on information from the timer 92 whether or not a predetermined time has elapsed since.

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 turned off, that is, when the drain pipe 6 determines that the sewage and the stirred filth 19 are not non-pumpable pipes (step S112: NO) , the drain 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.
