Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view of a toilet bowl 1 with a local cleaning device attached to a toilet room. As shown in FIG. 1, the main body 2 is provided with a pair of nozzles 3 for ejecting washing water toward the human body, a deodorizing fan (not shown), a pump for ejecting washing water from the nozzles 3, and the like. . A tank 4 for storing the washing water is attached to a rear portion of the main body 2, and a control board (a control board (not shown)) that forms a control circuit for controlling devices such as the nozzle 3, a deodorizing fan, and a pump is provided below the tank 4. (Not shown) is provided.

On the other hand, a remote control panel 5 for transmitting an optical signal for controlling devices such as the nozzle 3, a deodorizing fan, a pump and the like is mounted on a wall surface of the toilet room. A plurality of operation switches 5A are provided on the remote control panel 5, and when one of the operation switches 5A is pressed, the operation signal of the operation switch is converted into the optical signal and emitted from the light emitting section 6. You.
The light signal emitted from the light emitting unit 6 is transmitted to the tank 4.
The light is received by the light receiving unit 7 disposed on the surface of the device, is photoelectrically converted, and is input to the control circuit. Therefore, the control circuit drives the corresponding device.

The remote control panel 5 is provided with a stop switch 5B. When the stop switch 5B is pressed, the stop signal of this switch is converted into an optical signal, emitted from the light emitting section 6, and emitted from the light receiving section 7. , The control circuit stops the device currently being driven.

The control board and the remote control panel 5 provided at the rear of the main body 2 have built-in microcomputers. Also, the main body 2
The main body panel 8 attached to the side of the remote control panel 5 confirms when the light signal emitted from the light emitting section 6 is received by the light receiving section 7 when the operation switch 5A of the remote control panel 5 is pressed. A buzzer 9 for generating a sound is provided.

Further, the remote control panel 5 is provided with a determination circuit for detecting the voltage of the battery and determining that the life of the battery is approaching. When the judgment circuit judges that the battery life is approaching, the voltage drop signal output from the judgment circuit is input to the microcomputer of the remote control panel 5.

Next, control of the remote control panel 5 by the microcomputer and the control board of the main body 2 by the microcomputer will be described. When the voltage drop signal output from the determination circuit is input to the microcomputer of the remote control panel 5,
The microcomputer recognizes that the battery life is approaching. When the operation switch 5A of the remote control panel 5 is pressed in a state where it is recognized by the microcomputer that the life of the battery is approaching, the microcomputer transmits the light signal emitted from the transmitting section 6 Change form. As an example of this form change, a special code is added at the end of the code of each operation switch 5A and the code of the stop switch 5B. When the light signal having the changed form is received by the light receiving section 7, the microcomputer of the main body section 2 changes the confirmation sound generated from the buzzer 9 from normal one to three, for example. Let it. Alternatively, the frequency of the confirmation sound is changed from a normal 1000 Hz to a high frequency of 2000 Hz so that the sound quality of the confirmation sound changes. Thereby, the user can recognize that the life of the battery of the remote control panel 5 is approaching.

In order to make the user recognize that the battery life of the remote control panel 5 is approaching as described above, a confirmation sound different from the confirmation sound when the battery life is sufficient is provided. , The form of the light signal emitted from the light emitting unit 6 when the operation switch 5A and the stop switch 5B of the remote control panel 5 are pressed is changed, but in other embodiments, When the operation switch 5A is pressed, another light signal is emitted from the light emitting unit 6 and received by the light receiving unit 7 without changing the form of the optical signal emitted from the light emitting unit 6 to be generated from the buzzer-9. The confirmation sound may be changed.

In the above embodiment, the user is made aware that the battery life of the remote control panel 5 is approaching due to a change in the confirmation sound by the buzzer 9 attached to the main body panel 8 of the main body 2. However, in another embodiment, a light-emitting diode is attached to the main body panel 8 instead of the buzzer 9 and the light-emitting state of the light-emitting diode is changed so that the battery life of the remote control panel 5 is reduced. May be recognized by the user. Alternatively, a buzzer 9 and a light emitting diode may be used in combination.

In another embodiment, when the microcomputer of the remote control panel 5 recognizes that the life of the battery is approaching, as described above, the microcomputer displays a message indicating that the life of the battery is approaching. The light-out signal from the battery is emitted from the light-emitting unit 6 and received by the light-receiving unit 7 separately from the optical signal by operating the operation switch 5A and the stop switch 5B. And the microcomputer of the main body 2 is
A buzzer attached to the main body panel 8 may be sounded or a light emitting diode may emit light based on the received light signal indicating that the battery has run out.

In the above embodiment, the remote control panel 5 controls the equipment of the toilet with the local cleaning device. However, the present invention is not limited to the remote control panel of the toilet with the local cleaning device. The present invention can also be applied to a remote control panel for controlling a bus or a remote control panel for controlling a similar device.

According to the first aspect of the present invention, the fact that the life of the battery is approaching can be displayed by the dead battery display means provided in the main body. This allows the user to know from the main body that the battery life of the remote control device is approaching.

According to the second aspect of the present invention, when the remote control signal is transmitted while the battery life is approaching, the form of the remote control signal is changed and transmitted. When the remote control signal is received by the receiving section, it is possible to display that the battery is approaching the end of life by means of a dead battery indicator provided in the main body. This allows the user to know from the main body that the battery life of the remote control device is approaching.

According to the third aspect of the present invention, when the remote control signal is transmitted while the battery life is approaching, the form of the remote control signal is changed and transmitted. When the remote control signal is received by the receiving section, the state of generation of a reception confirmation sound or reception confirmation light by a display means such as a buzzer or a light emitting element provided in the main body can be changed. This allows the user to know from the main body that the battery life of the remote control device is approaching.
