BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a transmission / reception apparatus according to an embodiment of the present invention.

FIG. 1 shows an embodiment in which the present invention is applied to a household gas water heater. Reference numeral 9 denotes a water heater, which is instructed to operate by a remote controller 10 as a transmission / reception device. The water heater 9 and the remote controller 10 have a main body transmitting and receiving unit 1 for transmitting and receiving a mutual radio signal.
1. A remote control transmitting / receiving unit 12 is provided for each. Remote control 1
0 indicates a switch 1 for inputting an operation instruction to the water heater 9.
3. A display unit 14 as operation information display means for displaying operation information such as an operation instruction signal from the switch 13, a hot water temperature detection signal from the water heater 9, the total amount of hot water supply, and a power supply stop indicating that power is being saved in the power supply. 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, and a driving instruction signal input by the switch 13 is detected by the detecting means 16. The power control unit 17 receives the detection signal from the detection unit 16 and supplies power to the remote control transmission / reception unit 12 and the like. The timer means 18 is an information judging means 1 for judging a signal transmitted / received by the remote control transmitting / receiving section 12 to / from the water heater 9.
9, a timer 20 for measuring a predetermined time according to the determination signal from the time of receiving the determination signal from the information determining means 19. When the timer 20 counts up a predetermined time, the timer 20 transmits the signal to the power supply control unit 17 as a clock signal.

The power control means 17 instructs the display unit 14 to display an operation instruction signal of the switch 13 at the time of input operation, and also instructs the display unit 14 to display the operation information. Further, at the time of receiving the timing signal, the display signal is switched from the display unit 14 to the display unit 15. Although not shown, an 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 construction of the transmission wiring with the water heater 9 by making the remote controller 10 wireless.

First, an outline of the operation will be described based on the above configuration. The detection means 16 which has input the switch 13 to start operation of the appliance and has received the operation instruction signal by this operation informs the power supply control means 17 that the operation of the switch 13 has been performed, and transmits the operation information. Send. When the main body transmission / reception unit 11 receives the operation state information, the water heater 9 starts operating and enters the operating state. When the operation state is established, the main body transmission / reception unit 11 transmits the operation state information to the remote control transmission / reception unit 12. When receiving the operating state information, the remote control transmitting / receiving unit 12 transmits the operating state information to the display unit 14.
The display unit 14 displays the operation state of the water heater 9.

In the above operation, the timer 20 receiving the detection signal of the operation instruction from the detection means 16 starts the measurement of the predetermined time a, but stops the measurement by receiving the operation state information of the water heater 9 from the remote control transmission / reception section 12. (If there is no reception of this operation state information and no input of an operation stop instruction signal by turning off the switch 13, 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 Stops the display in the auto-off state, and the display unit 15 displays that fact instead).

After the hot water supply is completed, the remote control transmitting / receiving section 12 receives the information of the stop of the hot water supply operation from the hot water supply device 9, and the timer 20 which has received the received signal starts measuring a predetermined time b and inputs other information. When the measurement of the predetermined time b is completed without receiving the signal, the display unit 14
Is stopped and that is displayed on the display unit 15. At the same time, the power supply control unit 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, and saves power supply that is larger than the power supply for display output of the display units 14 and 15.

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 transmitting / receiving unit 12 includes a detecting unit 16
The received information is sent to the water heater 9 as a signal. The information judging means 19 includes a switch 13
When the transmission of the signal by the operation is detected, the timer 20 starts counting time. The display unit 14 displays the content operated by the switch 13, and the display unit 15 stops displaying.

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 water heater 9 is input to the timer 20 via the main body transceiver 11 and the remote controller transceiver 12, and the timer 20 is started. Stops timing.
If the hot water supply is not performed after the hot water temperature setting is changed, that is, if the hot water temperature is changed but the hot water supply is not executed, the display of information is only useless. The supply of power is stopped, and the fact is displayed on the display unit 15.

The remote control transmission / reception unit 12 also inputs the hot water supply information of the water heater 9 by another remote control (not shown) to the remote control 10. The hot water supply information is stored in the remote control 10.
And the same as the operation information of the water heater 9 according to the instruction. In other words, 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 is supplied with power from the power control means 17. In response to this, the operating information from the other remote controller can be received from the water heater 9 and displayed on the display unit 14, thereby improving the usability of the hot water temperature setting.

Further, for example, when an automatic hot water supply operation for a bath is performed, the operation of the switch 13 starts the operation of the water heater 9 as described above, and the operation state is displayed on the display unit 14 of the remote controller 10. At this time, the remote control transmitting / receiving unit 1
The information determining means 19 that determines the signal transmitted and received by the second unit 2 stops the timer 20 from counting time and continues the display on the display unit 14 during the continuation of the automatic operation. Thereafter, when the automatic operation to the bath is completed, the remote control transmission / reception section 12 receives the hot water supply operation stop signal sent from the main body transmission / reception section 11, and the information determination section 19 determines the signal to stop the timer 20.
The power supply of the remote controller 10 and the display of the display unit 14 are stopped after a predetermined time b, and the display unit 15 displays the fact instead.

Therefore, the display is displayed on the display unit 14 only for a predetermined period a, b according to the use state in which the user needs the display information, and the user confirms the completion of driving, and in particular, displays the display information on the display unit 14. The display is automatically stopped when no monitoring is required or when monitoring is stopped, and the
Will be displayed.

When the switch 13 is operated to stop the operation of the appliance, the user needs the display information of the display unit 14 after the operation of the switch 13 because the operation of the appliance is stopped. It is a short time to confirm. Therefore, the power supply of the remote controller 10 and the display on the display unit 14 are not stopped at the same predetermined time a as when the operation of the appliance is started, but when the information determination unit 19 determines the stop information of the appliance, This is realized by shortening the predetermined time b of the timer 20.

As described above, the information judging means 19 and the timer 2
When the wireless communication is not required between the remote controller 10 and the water heater 9, the power control means 17 stops the useless power supply to the remote controller transmission / reception unit 12 minutely and finely according to the case to save power. Can be. And the switch 13
The power saving can be realized by the operation input of, the detecting operation of the detecting means 16 and the slight power supply to the display unit 15.

In addition, while obtaining this power saving effect, it is always ready for a re-operation input by the switch 13 and the display unit 15
Even if the display of the display unit 14 is stopped by the display, it is possible to prevent erroneous determination such as failure. Furthermore, the display unit 1
If the display is stopped by any of the display units 4 and 15, this clearly indicates that the function of the remote controller 10 has failed.
Has the merit that the malfunction of the remote controller 10 as the function abnormality can be indicated separately from other displays.

[0028]

As described above, according to the transmission / reception apparatus of the present invention, the timer means changes the predetermined time based on the operation state of the appliance and the contents of the information of the operated switch to display the operation information relating to the operation state of the appliance. The power supply stop display means stops power supply for power saving while displaying the means and controlling the power supply from the power control means to the transmission / reception means by time to reduce the power consumption of the power control means due to unnecessary power supply. Is displayed, it is possible to prevent a malfunction of the apparatus and an erroneous determination that the power supply cannot be performed by the power supply control means, and more effective power saving is achieved.
