DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a wireless transmitting / receiving apparatus of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment in which the present invention is applied to a domestic gas water heater, and 9 is a water heater, which is instructed to operate by a remote controller 10 as a transmitter / receiver. The water heater 9 and the remote controller 10 transmit / receive wireless signals to / from each other by the main body transceiver unit 1
1. Each includes a remote control transmission / reception unit 12. Remote control 1
0 is a switch 1 for input operation for instructing operation to the water heater 9.
3. A display unit 14 as a driving information display unit for displaying driving instruction signals from the switch 13, hot water temperature detection signals from the water heater 9, total driving amount of hot water, etc., power supply stop for displaying power saving A display unit 15 as a display unit is provided on the front.

FIG. 2 is a control block diagram of the remote controller 10, in which the driving instruction signal input by the switch 13 is detected by the detecting means 16. The power supply control means 17 receives the detection signal from the detection means 16 and supplies power to the remote controller transmission / reception unit 12 and the like. The timer means 18 is the information judging means 1 for judging the signal transmitted / received by the remote controller transmitter / receiver 12 to / from the water heater 9.
9. A timer 20 for measuring a predetermined time according to the judgment signal from the time when the judgment signal is received from the information judging means 19. When the timer 20 counts up the predetermined time, it is transmitted to the power supply control means 17 as a time signal.

The power source control means 17 instructs the display unit 14 to display the operation instruction signal of the switch 13 from the time of input operation, and also instructs the display unit 14 to display the operation information. Further, the display signal is switched from the display unit 14 to the display unit 15 when the time signal is received. Although not shown, the electronic controller such as the detecting means 16 is built in the remote controller 10. The power supply control means 17 employs a battery (not shown) instead of the power supply by the AC power supply in order to simplify the transmission wiring work with the water heater 9 by making the remote controller 10 wireless.

Based on the above configuration, the outline of the operation will be described first. The detection means 16 that has input the switch 13 to start the operation of the appliance and received the operation instruction signal by this operation informs the power source control means 17 that the operation of the switch 13 has been performed, and also outputs the operation information. Send. When the main body transmitter / receiver 11 receives the operation state information, the water heater 9 starts operating and enters the operating state. When in the operating state, the main body transmitting / receiving unit 11 transmits the operating state information to the remote control transmitting / receiving unit 12. Upon receiving the driving condition information, the remote controller transmitting / receiving unit 12 transmits the driving condition information to the display unit 14.
The display unit 14 displays the operating state of the water heater 9.

In the above-mentioned operation, the timer 20 which receives the detection signal of the driving instruction from the detecting means 16 starts the measurement of the predetermined time a, but stops the measurement upon receiving the operating state information of the water heater 9 from the remote control transmitting / receiving section 12. (If the operation state information is not received and the operation stop instruction signal for turning off the switch 13 is not input, the power supply of the remote controller 10 is stopped when the measurement of the predetermined time a is completed, and the display unit 14 is operated. Stops the display in the auto-off state, and the display unit 15 displays the fact instead).

After the hot water supply is completed, the remote controller transmission / reception unit 12 receives the information about the hot water supply operation stop from the water heater 9, and the timer 20 to which this received signal is input starts the measurement of the predetermined time b and inputs other information. When the measurement of the predetermined time b is completed without receiving the measurement, at the same time when the measurement of the predetermined time a is completed, the display unit 14
Is stopped and the display unit 15 displays that effect. At the same time, the power supply control means 17 stops the power supply for the remote control transmission / reception unit 12 to prepare for communication with the main body transmission / reception unit 11 to save more power than the power supply for display output of the display units 14 and 15, and to save battery power. Prevent consumption.

Next, when the switch 13 is operated again to change the setting of the hot water supply temperature, the power supply control means 17 receives a signal from the detection means 16 and supplies power to the remote control transmission / reception section 12 again. The remote control transmission / reception unit 12 uses the detection means 16
The received information is sent to the water heater 9 as a wireless signal. When the remote control transmission / reception unit 12 detects that the signal is transmitted by the operation of the switch 13, the information determination unit 19 starts the timer 20 to count the time. The display unit 14 displays the contents operated by the switch 13, and the display unit 15 stops the display.

When the hot water supply is started before the timer 20 completes the measurement of the predetermined time b, the operation start signal of the hot water supply device 9 is input to the timer 20 via the main body transceiver 11 and the remote control transceiver 12, and the timer 20 Stops timing.
If hot water is not supplied after changing the setting of the hot water supply temperature, that is, if the setting of the hot water supply temperature is changed but the hot water supply is not executed, the information display is useless, and therefore the wireless communication to the remote control transmission / reception unit 12 is performed. The supply of power is stopped, and the fact is displayed on the display unit 15.

The remote controller transmitter / receiver 12 also inputs hot water supply information of the water heater 9 from another remote controller (not shown) to the remote controller 10. And this hot water supply information is the remote control 10
The same as the operation information of the water heater 9 according to the instruction. That is, if the water heater 9 is operated by another remote controller even if the remote controller 10 does not supply hot water at all, the switch 13 is operated and input by the remote controller 10 and the remote controller transceiver 12 supplies power from the power control means 17. When receiving the information, the operation information from the other remote controller can be received from the water heater 9 and displayed on the display unit 14, which facilitates the setting of the hot water temperature.

Further, for example, in the case of the automatic hot water supply operation to the bath, the water heater 9 starts to operate by operating the switch 13 as described above, and the operating state is displayed on the display unit 14 of the remote controller 10. At this time, the remote controller transceiver 1
The information judging means 19 for judging the signal transmitted and received by the device 2 stops the timer 20 while the automatic operation is continued and continues the display on the display unit 14. After that, when the automatic operation to the bath is completed, the remote control transmission / reception unit 12 receives the wireless signal of the hot water supply operation stop sent from the main body transmission / reception unit 11,
This signal is judged by the information judging means 19 and the timer 20 which has been stopped is initialized, whereby the predetermined time b
The power supply of the rear remote controller 10 and the display of the display unit 14 are stopped, and instead, the display unit 15 displays that effect.

Therefore, the user displays the information on the display unit 14 only for a predetermined period a or b corresponding to the use condition for which the display information is required, and the user confirms the completion of the driving, especially the display information on the display unit 14. The display unit 15 automatically stops the display when the monitoring is not required and when the monitoring is stopped.
Will be displayed.

When the switch 13 is operated to stop the operation of the instrument, the user needs the display information of the display unit 14 after the operation of the switch 13 when the operation of the instrument is stopped. It's a short time to confirm. Therefore, instead of stopping the power supply of the remote controller 10 and the display of the display unit 14 at the predetermined time a similar to the case of starting the operation of the above-mentioned equipment, when the information determination means 19 determines the equipment stop information, This is realized by shortening the predetermined time b of the timer 20.

In this way, the information judging means 19 and the timer 2
When the wireless communication between the remote controller 10 and the water heater 9 is unnecessary, the power control means 17 stops the wasteful power supply to the remote controller transmission / reception unit 12 finely depending on the case by the action of 0, and battery consumption is reduced. It can be reduced. And
The operation input of the switch 13 and the detection operation of the detection means 16,
Power can be saved by supplying a small amount of power to the display unit 15.

Moreover, while obtaining this power saving effect, the display unit 15 is ready for re-operation input by the switch 13 at any time.
Even if the display of the display unit 14 is stopped by the display of, the erroneous determination such as a failure can be prevented. Furthermore, the display unit 1
If both 4 and 15 stop displaying, it clearly indicates that the function of the remote controller 10 has an abnormality.
The addition of (3) also has the advantage that the failure of the remote controller 10 as this abnormal function can be shown separately from other displays.

[0023]

As described above, in the wireless transmission / reception apparatus of the present invention, the timer means changes the predetermined time based on the judgment contents of the operating state of the appliance and the information of the operated switch, and the operating information on the operating state of the appliance. The power supply for saving power is provided by the power supply stop display means while the display of the display means and the power supply from the power supply control means to the transmission / reception means are time-controlled to reduce the power consumption of the power supply control means due to unnecessary power supply. It is possible to prevent the erroneous determination that the device is broken down or that the power supply control means cannot supply the power by displaying the fact of the stop, and more effective power saving is achieved.
