Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless transmitter / receiver device for transmitting / receiving operation information of a water heater or the like as a wireless signal to / from the water heater or the like.

[0002]

2. Description of the Related Art A remote controller (hereinafter, also referred to as a remote controller) as a conventional wireless transmitting / receiving means is shown in FIG.
Shown in. In this figure, 1 is a switch for giving a driving instruction to a water heater (not shown), 2 is a detecting means, 3 is a power source controlling means, 4 is a transmitting / receiving means, 5 is an information judging means, 6 is a timer means, and 7 is a driving instruction. It is a signal display means. When the switch 1 is operated while the power supply control means 3 is not supplying power to the transmission / reception means 4, the detection means 2 notifies the power supply control means 3 that the switch 1 has been operated and was operated. The contents of the switch 1 are transmitted to the transmitting / receiving means 4. When the power supply control means 3 receives a signal from the detection means 2, it supplies power to the transmission / reception means 4. The transmission / reception unit 4 transmits the information received from the detection unit 2 to the water heater as a wireless signal. When the switch 1 is not operated and the timer means 6 finishes measuring a predetermined time, a signal is applied to the power supply control means 3, and the power supply control means 3 stops the supply of power to the transmission / reception means 4 and the display means 7. Then, the transmission and reception with the water heater were stopped, and the display was also stopped.

With the above-described structure and operation, the conventional wireless transmission / reception apparatus controls the power supply to the transmission / reception means 4 by operating the switch 1 and the time measurement by the timer means 6,
The power consumption is reduced by stopping the power supply of the power supply control means 3 by the battery power supply after the predetermined time.

[0004]

However, in the conventional wireless transmission / reception apparatus, the display means 7 is used even though the user is ignorant of the mechanism for stopping the power supply or forgets it and has already operated the switch 1. Since the display of the driving instruction signal and the like to the display is stopped, there is a problem in that it is erroneously determined that the driving input has not been executed, and that it is erroneously determined that the device has failed or the battery power has been exhausted.

Therefore, the present invention provides a wireless transmission / reception device capable of preventing the erroneous determination of the operating state of the appliance while reducing the power consumption of the power supply control means.

[0006]

In order to achieve the above object, the means of the wireless transmission / reception device of the present invention comprises a switch for instructing a remotely installed instrument to operate, a detection means for detecting an operation signal of the switch, and a wireless signal. As a transmitting and receiving means for transmitting and receiving to and from the appliance, a power supply control means for supplying power to the device, and starting time measurement from the time when it is determined to execute a driving instruction to the appliance by a signal from the transmitting and receiving means,
A timer means for outputting a power supply stop signal to the power supply control means when a predetermined time is timed, and a power supply stop indication for receiving the stop signal of the timer means and displaying that power supply from the power supply control means to the transmitting / receiving means is stopped. And a driving information display means for displaying the driving instruction signal of the switch and the driving information from the appliance within the predetermined time.

[0007]

According to the present invention, with the above-mentioned structure, the detecting means detects the operation of the switch and transmits it to the power supply controlling means. The power supply control means starts the supply of power to the transmission / reception means in response to the signal from the detection means. The timer means determines whether or not predetermined information is transmitted from the transmitting / receiving means, and stops or initializes the clocking. Further, when the switch operation instruction signal is received, a predetermined time is measured and the result is transmitted to the power supply control means. The power supply control means stops the supply of power to the transmission / reception means in response to the signal from the timer means. The power supply stop display means indicates to the user that the supply of power to the transmission / reception means is stopped after the operation information display means is stopped to inform the user that the display stop is not a failure or a stop due to power consumption. .

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 an information judging means 19 for judging the signal in which the remote control transmitting / receiving section 12 has transmitted the operation instruction signal of the switch 13 to the water heater 9, and a timer for measuring a predetermined time from the time of receiving the judgment signal from the information judging means 19. It consists of 20. 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 detecting means 16 that has received an operation instruction signal by operating the switch 13 by inputting the switch 13 is operated by the switch 13
The operation information is transmitted to the power supply control means 17 and the operation information is transmitted. 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. When the switch 13 is not operated after the predetermined time of the timer 20, the power supply of the remote controller 10 is stopped in order to reduce the power consumption of the remote controller 10. At this time, the display unit 14 stops the display in the auto-off state, and the display unit 15 displays that effect instead.

When the hot water is supplied to the bathtub or the like for a long time, for example, the user does not need the display information of the display unit 14 and does not monitor it. Power consumption can be reduced. Also,
It is possible to reduce unnecessary load of electric power to the electronic controller and reduce the load on the circuit element.

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 transmitter / receiver 12 detects the transmission of a signal by the operation of the switch 13, the information judging means 19 initializes the time measurement of the timer 20. The display unit 14 displays the contents operated by the switch 13, and the display unit 15 stops the display.

If the switch 13 is operated while power is being supplied to the remote control transmitter / receiver 12, the detection means 16 conveys the content of the operation to the remote controller transmitter / receiver 12, and the remote controller transmitter / receiver 12 uses the information as a wireless signal. Then, the information judging means 19 initializes the time measurement of the timer 20.

In this way, the power supply control means 17 stops the wasteful power supply to the remote control transmission / reception unit 12 when the remote control transmission / reception unit 12 does not need wireless communication with the water heater 9, thereby draining the battery. be able to. And switch 13
The power saving can be realized by the operation input of 1, the detection operation of the detecting means 16, and the slight power supply to the display unit 15. Moreover, while obtaining this power saving, the display unit 15 is always ready for the re-operation input by the switch 13 and the display unit 15 displays.
Even if the display of is stopped, the intervention of erroneous judgment such as a failure can be prevented. Furthermore, when the display units 14 and 15 stop displaying at the same time, it clearly indicates that the function of the remote controller 10 has an abnormality, and the addition of the display unit 15 indicates that the function of the remote controller 10 is abnormal. It can be said that it also has the merit of being able to distinguish the failure from other displays.

[0017]

As described above, in the wireless transmission / reception device of the present invention, when the timer means measures a predetermined time from the time when the operation instruction signal of the appliance is input by the switch, the operation instruction signal and the operation information of the appliance are obtained. Related to the operation information display means and the power supply from the power supply control means to the transmission / reception means to stop power consumption of the power supply control means by unnecessary power supply, and the power supply stop display means to save power. By displaying the fact that the power supply is stopped, it is possible to prevent erroneous judgment that the device is out of order or the power supply control means cannot supply the power, and more effective power saving can be achieved.
