<Composition of toilet equipment>
First, a toilet apparatus according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a configuration diagram schematically illustrating a toilet apparatus according to an embodiment of the present invention.

  As shown in FIG. 1, the toilet apparatus 100 includes a toilet body 200, a water storage tank 300 that stores cleaning water, a pump 600 that pumps cleaning water supplied from the water storage tank 300 to the toilet body 200, and a cleaning of the toilet body 200. A controller 700 that performs control in operation and a notification unit 900 that performs notification by sound are provided.

  The toilet body 200 is rimmed by a bowl 202 formed as a recess opening upward on the upper surface of the toilet body 200, a drain trap 204 extending from the bottom of the bowl 202, and washing water supplied from the water supply source 50. A rim water spouting unit 210 that performs water spouting and a jet water spouting unit 230 that performs jet water spouting with the wash water supplied from the water storage tank 300 are formed.

  The drain trap 204 is an S-shaped trap pipe, and when the pipe is full and siphon action occurs, washing water containing dirt is discharged to a drain port (not shown). The rim water discharge unit 210 is formed on the upper side of the bowl unit 202, and discharges cleaning water along the edge of the bowl unit 202. The jet water spouting portion 230 is formed at the bottom of the bowl portion 202 and is arranged substantially horizontally toward the inlet of the drain trap 204 so as to discharge cleaning water toward the drain trap 204.

  The water storage tank 300 is provided with an upper end float switch 310 and a lower end float switch 320. The upper end float switch 310 is turned on when the water level in the water storage tank 300 rises to a predetermined water level W1, and the controller 700 detects this and controls the water storage in the water storage tank 300 to stop. The lower end float switch 320 is turned on when the water level in the water storage tank 300 drops to the predetermined water level W2, and the controller 700 detects this and controls the pump 600 to stop driving.

  The pump 600 has a motor 610, and when the motor 610 is driven in response to the control signal 610 </ b> A from the controller 700, the cleaning water supplied from the water storage tank 300 is pumped to the jet water spouting unit 230. When the wash water is pumped to the jet water spouting unit 230, the jet water is discharged to the toilet body 200 by passing through the jet side flow path 232 and being supplied to the jet water spouting unit 230.

  Upon receiving the notification signal 900A output from the controller 700, the notification unit 900 performs notification with a buzzer sound for a predetermined time.

  The wash water supplied from the water supply source 50 first flows into the solenoid valve 400. The electromagnetic valve 400 starts or stops supplying cleaning water to the downstream side of the electromagnetic valve 400 by opening and closing in response to the control signal 400A from the controller 700.

  The wash water that has passed through the electromagnetic valve 400 flows into the flow path switching valve 500. Based on the control signal 500A received from the controller 700, the flow path switching valve 500 switches between flowing the wash water into the rim side flow path 212 or the tank side flow path 302. When water is passed through the rim side channel 212, the cleaning water is discharged from the rim water discharge unit 210 to the bowl unit 202 after passing through the rim side channel 212. When water is passed through the tank side flow path 302, the wash water is stored in the water storage tank 300.

  When a user inputs a cleaning start switch to the operation unit 800, a cleaning start signal 800A is output from the operation unit 800 to the controller 700. Upon receiving the cleaning start signal 800A, the controller 700 starts the cleaning operation of the toilet body 200.

<Motor power input circuit configuration>
Next, a power input circuit for a motor according to an embodiment of the present invention will be described with reference to FIG. FIG. 2 is a block diagram schematically showing a power input circuit configuration of the motor according to the embodiment of the present invention.

  As shown in FIG. 2, electric power necessary for driving is supplied to the motor 610 by the power input circuit 10. The power input circuit 10 includes a commercial power source 20 and a rectifying / smoothing circuit 30. The AC voltage supplied from the commercial power source 20 is converted into a DC voltage by the rectifying / smoothing circuit 30 and then drives the motor 610. A driving voltage is supplied.

  The rectifying / smoothing circuit 30 includes a smoothing capacitor 31, an inrush current preventing component 33, and a relay 35.

  The smoothing capacitor 31 is charged by the electric power supplied from the commercial power source 20 and drives the motor 610 by the charged electric power. When the power supplied from the commercial power supply 20 is large, a large inrush current may flow temporarily when the power is turned on. If this inrush current flows through the smoothing capacitor 31, the driving operation of the motor 610 may be adversely affected. Therefore, the rectifying and smoothing circuit 30 includes an inrush current preventing component 33 in order to reduce the inrush current.

  The inrush current preventing component 33 is composed of an element having a resistance. FIG. 2 shows a power thermistor whose resistance value decreases as the temperature rises as the inrush current prevention component 33. By flowing a current through the inrush current preventing component 33 when the commercial power supply 20 is turned on (when the power supply voltage is turned on), the inrush current to the smoothing capacitor 31 can be reduced. A relay 35 is connected in parallel to the inrush current prevention component 33. The relay 35 is configured as a mechanical relay that mechanically opens and closes contacts, and bypasses the current flowing to the inrush current prevention component 33 by setting the relay 35 in a connected state.

  The relay controller 25 controls the opening and closing of the relay 35 based on the control of the controller 700. The relay control unit 25 disconnects the relay 35 so that current flows through the inrush current prevention component 33 when the power is turned on, and bypasses the current flowing through the inrush current prevention component 33 in a state where the inrush current does not flow. Thus, the relay 35 is set in a connected state. Thus, since the inrush current that flows when the power is turned on passes through the inrush current prevention component 33, the inrush current flowing to the smoothing capacitor 31 can be reduced, and in a state where there is no possibility of the inrush current flowing, the inrush current prevention component 33 passes. Therefore, power loss in the power input circuit 10 can be suppressed.

<Operation of toilet device>
Next, the operation of the toilet apparatus according to the embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a flowchart showing a series of operations of the toilet apparatus during cleaning of the toilet bowl body according to the embodiment of the present invention.

Before starting the cleaning of the toilet body, the relay 35 is in a disconnected state, and the flow path switching valve 500 is in a standby state in which neither the rim-side flow path 212 nor the tank-side flow path 302 is passing water. .

  As shown in FIGS. 3 and 4, when a cleaning start switch is input to the operation unit 800 at time t1 (step S1), a cleaning start signal 800A is output from the operation unit 800 to the controller 700.

  When the controller 700 receives the cleaning start signal 800A, the control signal is transmitted so that the drive signal 400A is passed to the rim side flow path 212 with respect to the flow path switching valve 500 so that the electromagnetic valve 400 starts to open. A notification signal 900A is output so that 500A is notified to the notification unit 900. As a result, at time t2, the electromagnetic valve 400 starts to open, the flow path switching valve 500 is switched to pass water to the rim side flow path 212, and the notification unit 900 starts notification by a buzzer sound as a notification sound. .

  At time t3, the controller 700 outputs a notification signal 900A to the notification unit 900 so as to end the notification. Thereby, the alerting | reporting part 900 complete | finishes the alerting | reporting by a buzzer sound. Therefore, a buzzer sound is generated from the notification unit 900 between time t2 and time t3 (F1). Between time t2 and time t3, the relay control unit 25 switches the relay 35 from the non-connected state to the connected state.

  The opening driving of the solenoid valve 400 started at time t2 is completed at time t4. Accordingly, the wash water supplied from the water supply source 50 and passed through the electromagnetic valve 400 and the flow path switching valve 500 is supplied to the rim water discharge section 210 through the rim side flow path 212, and rim water discharge to the toilet body 200 is started.

  At time t <b> 6, the water level in the water storage tank 300 decreases due to jet water spouting to the toilet body 200, and the lower end float switch 320 of the water storage tank 300 is turned on, and the controller 700 detects this and drives the motor 610. The control signal 610A is output so as to stop. Thereby, the motor 610 stops driving, and the jet water discharge to the toilet body 200 is terminated by stopping the pumping of the wash water from the water storage tank 300 to the jet water discharge section 230 by the pump 600 (step S4). In addition, the suction sound accompanying the siphon action generated in the drain trap 204 is generated between time t5 and time t6 when jet water discharge to the toilet body 200 is performed (F3).

  At time t <b> 7, the controller 700 outputs a control signal 500 </ b> A so that water flows to the tank side flow path 302 with respect to the flow path switching valve 500. Thereby, the flow path switching valve 500 is switched so as to pass water to the tank side flow path 302, and the rim water discharge to the toilet main body 200 is completed and the water supply to the water storage tank 300 is started (step S5).

  At time t8, the water level in the water storage tank 300 rises, the upper end float switch 310 of the water storage tank 300 is turned on, and the controller 700 detects this and a drive signal so that the solenoid valve 400 starts to be closed. A control signal 500A is output so that 400A enters a standby state with respect to the flow path switching valve 500. As a result, the electromagnetic valve 400 starts to be closed, the flow path switching valve 500 enters a standby state, and the water supply to the water storage tank 300 ends (step S6). In addition, the water supply sound accompanying the water supply to the water storage tank 300 is generated between the time t7 and the time t8 (F5). Between time t7 and time t8, the relay 35 is switched from the connected state to the disconnected state. In this way, a series of operations of the toilet apparatus 100 during the cleaning of the toilet body 200 is completed.

  As described above, in the toilet apparatus 100 according to the present embodiment, the controller 700 disables the relay 35 while the buzzer sound of the notification unit 900 generated before the start of driving of the motor 610 during the cleaning operation is generated. The switching control from the connected state to the connected state is performed, and the relay 35 is switched from the connected state to the disconnected state while the water supply sound to the water storage tank 300 generated after the completion of the driving of the motor 610 during the cleaning operation is generated. . That is, in the present embodiment, the buzzer sound notified from the notification unit 900 is the first generated sound generated before the motor 610 starts to be driven, and the water supply sound generated when the cleaning water is supplied to the water storage tank 300 is generated. The second generated sound generated after the driving of the motor 610 is completed.
