FIG. 2 is a circuit diagram of the battery-powered remote control device of FIG. 1. It is a flowchart which shows the action | operation of the battery-powered remote control apparatus of FIG. It is explanatory drawing of the action | operation of the battery-powered remote control apparatus of FIG.

  Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view of a toilet 1 with a hot water cleaning device. In the tank cover 4 installed on the rear upper surface of the main body 2 of the toilet bowl, in addition to the low tank, a pair of nozzles 3 for ejecting washing water toward the human body part, a deodorizing fan (not shown), and the nozzle 3 A water supply pump, a control board equipped with a control circuit, etc. are installed.

  A remote controller 5 incorporating a battery and a control board is attached to the wall surface of the toilet room. The remote controller 5 is provided with a plurality of operation switches 5A. When one of the operation switches 5A is pressed, an operation signal light corresponding to the content of the operation switch is transmitted from the light emitting unit 6. The optical signal transmitted from the light emitting unit 6 is received by the light receiving unit 7 provided in the tank cover 4, photoelectrically converted and input to the control circuit in the tank cover 4, and the control circuit controls driving of the corresponding device. .

  The remote control 5 is provided with a stop switch 5B. When the stop switch 5B is pressed, a stop signal is transmitted from the light emitting unit 6, and when the stop signal light is received by the light receiving unit 7, the control circuit stops the device that is being driven at that time.

As shown in FIG. 2, the control board of the remote controller 5 includes a microcomputer 12 as a control unit. Between the power input terminal Vin and the ground terminal G of the microcomputer 12, a voltage from a battery (dry battery in this embodiment) 10 is input via electrolytic capacitors C ₁ and C ₂ and a resistor 11. Between the positive electrode of the battery 10 and the ground, LEDs 14 and 15 are connected in parallel via resistors 12 and 13 and a transistor 16.

  The LEDs 14 and 15 are disposed on the back side of each light emitting unit 6 and emit signal light.

  The control board in the remote controller 5 is provided with a voltage determination circuit 17 for determining an input voltage to the microcomputer, and the determination result of the voltage determination circuit 17 is input to the microcomputer 12.

  The microcomputer 12 controls the transistor 16 based on signals from the operation switch 5 </ b> A, the stop switch 5 </ b> B, and the voltage determination circuit 17, and performs display control of the liquid crystal display panel 8 on the front surface of the remote controller 5. The microcomputer 12 is installed with a software program for counting the number of operations of the operation switch 5A and the stop switch 5B, and a software program for measuring the elapsed time since the battery was set in the remote controller 5.

  As shown in FIGS. 3 and 4, when the voltage of the battery is higher than a set value (for example, 2.6 volts) by the voltage determination circuit 17, it is in the normal mode, and the remote controller 5 operates normally. When the battery voltage becomes equal to or lower than the set value, a voltage drop signal from the voltage determination circuit 17 is input to the microcomputer 12, and the microcomputer 12 displays a battery exhaustion display mark on the liquid crystal panel 8.

  It is possible to know that the battery has run out by turning on the battery running indication mark. In this mode (battery exhaust warning mode), only the battery exhaustion mark is displayed, and the remote controller 5 itself can be used in the same manner as in the normal mode, and each device can operate in the same manner.

  The microcomputer 12 counts the number of operations of the stop switch 5B of the remote controller 5 after displaying the battery deadline display mark, and determines whether this number is equal to or greater than the set number. When the battery voltage recovers to the set voltage or more while the number of operations is less than the set number, the battery exhaustion display is erased, the count number is reset to zero, and the count is stopped.

  If the battery voltage does not recover, the count is continued as it is, and when the number of operations exceeds the set number, the mode is shifted to the stop mode, and the devices of the main body 2 such as the nozzle 3, the deodorizing fan, and the pump are operated. In such a case, after the stop signal for stopping the operation of the device is emitted from the light emitting unit 6, no light signal is emitted from the light emitting unit 6 even if the operation switch 5A is operated. Thereby, even if the operation switch is operated, the device does not operate.

In this embodiment, thereafter, the transistor 16 is turned on for a predetermined time, and the capacitors C ₁ and C ₂ are discharged. Thereby, the microcomputer 12 is reset. Thereafter, when the battery 10 is replaced with a new one, the microcomputer 12 returns to the normal mode.

In the above embodiment, when transition to the stop mode, the capacitor C ₁ by although to discharge the capacitor C _1, C ₂ so that the transistor 16 and ON, which the microcomputer 12 and the high power consumption active mode, the C ₂ may be discharged.

  In the above embodiment, the number of operations of the stop switch is counted after shifting from the normal mode to the battery low warning mode. However, the number of operations of the operation switch 5A after shifting to the battery low warning mode is counted. Alternatively, the total number of operations of the operation switch 5A and the stop switch 5B may be counted.

  In the present invention, the elapsed time may be measured after shifting to the battery exhaustion warning mode, and the mode may be shifted to the stop mode when the elapsed time reaches a predetermined time.

  In addition, after shifting to the battery exhaustion warning mode, the stop switch operation count and elapsed time measurement are performed in parallel, and if either the operation count or elapsed time reaches a predetermined value, the stop mode is entered. You may make it transfer.

  The battery exhaustion may be indicated by lighting or blinking of a warning LED.
