Power consumption was reduced by stopping the supply of external power (hereinafter also referred to as the auto-off function).

[0005]

However, in the conventional wireless transmission / reception device, the user is ignorant of the mechanism for stopping the power supply, or the switch 1 is already in use.
Since the display of the driving instruction signal or the like on the display means 7 is stopped even though the operation input has been performed, it is mistakenly mistakenly forgotten that the driving input has not been executed yet, or that the device has malfunctioned or the battery power has been exhausted. There was a problem of making a decision.

On the other hand, in order to solve the above-mentioned problems, it is easy to abolish the auto-off function and continuously perform transmission / reception with the water heater and display, but the above-mentioned method consumes much power and is realized. Has not yet reached. Therefore, according to the present invention, the predetermined time from the user's use to the operation of the auto-off function is changed based on the frequency of use, and it is as if the auto-off function was abolished under conditions of high frequency of use.

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. Water heater 9 and remote control 1
0 is a main body transmission / reception unit 11 for transmitting / receiving mutual radio signals,
Each is equipped with a remote control transmission / reception unit 12. Remote control 1
Input switch 1 for operating the water heater 9 at 0
3. A display unit 14 is provided on the front surface as a driving information display unit for displaying driving information from the switch 13, a water heater usage signal from the water heater 9, a hot water temperature detection signal, a total hot water supply amount, and the like.

FIG. 2 shows a control block of the remote controller 10, in which a switch detecting means 15 detects a driving instruction signal input by the switch 13. On the other hand, when the user performs hot water supply or the like, the remote controller transmission / reception unit 12 receives the operation signal of the appliance transmitted from the main body transmission / reception unit 11. The appliance operation detection unit 16 detects only hot water supply from the remote control transmission / reception unit 12. The operation of the switch 13 and the instrument operation information via the remote control transmission / reception unit 12 are sent to the display unit 14 as a display signal. The counter part 17 integrates the number of times the switch 13 is operated from the switch detector 15 and the number of times the instrument is used received from the instrument operation detector 16 while the learning timer 18 counts the time. When the time is up, the learning timer unit 18 resets and restarts the integrated value of the counter unit 17 and its own timer value, and outputs the integrated value to the next stage.

The counter content storage unit 19 receives the integrated value from the timer unit 18, allocates the integrated value to the time axis and sequentially stores them. The clock unit 20 gives the current time to the counter content storage unit 19 and also measures the counter content storage unit 1 when it measures a predetermined time.
The stored contents of 9 and the own predetermined time are reset. The learning unit 21 receives the integrated value of each time assigned to the time axis from the counter content storage unit 19 and the time, and changes them in order of increasing integrated value. Next, the power supply period for supplying power to the remote control transmission / reception unit 12 and the display unit 14 is assigned to the longest in the order of increasing integrated value, the power supply time is determined from what time to what time on the time axis, and every power cycle is determined. To the next stage. Further, the content of the learning unit 21 is updated every time the counter content storage unit 19 outputs.

The display timer information judging means 22 receives and stores the power supply time from the learning section 21. This memory is updated when the power supply time from the learning unit 21 is changed. Further, the display timer information determination means 22 sends a start and reset start signal for measuring the power supply time to the next stage by an operation or a received signal from the switch detection means 15 and the appliance operation detection unit 16.

The display timer section 23 receives the power supply time value from the display timer information judging means 22 and measures the time. In addition, a power supply is supplied during counting, and a power stop signal is sent to the next stage at other times.

The power control means 24 includes a display timer section 23.
The power supply is controlled by the signal from. Although an electronic controller such as the switch detection means 15 is not shown, a battery (not shown) is used instead of the power supply by the AC power source in order to simplify the transmission wiring work with the water heater 11 by making the remote controller 10 wireless. is doing.

First, an outline of the operation will be described based on the above configuration. The switch detection means 15 which inputs the switch 13 to start the operation of the appliance and receives the operation instruction signal by this operation notifies the display timer information determination means 22 that the operation of the switch 13 has been performed, and The operation information is transmitted to the counter unit 17 every time the driving instruction signal is received, and the addition information of +1 is transmitted.

On the other hand, when the user uses the hot water supply, the hot water supply use information is wirelessly transmitted to the remote control transmission / reception unit 12 via the main body transmission / reception unit 11. Remote control transceiver 1
The information transmitted to 2 is transmitted to the appliance operation detecting unit 16, but the appliance operation detecting unit 16 detects only the information that the user has used the hot water supply or the like, and the counter unit 17 +
The addition information of 1 is transmitted.

The counter unit 17 continues to accumulate the addition information of the switch detection unit 15 and the appliance operation detection unit 16 up to a timer value (for example, 30 minutes) preset in the learning timer unit 18, and is zero if the learning timer unit 18 is up. Counter content storage unit 1 at the same time as clearing and waiting for additional information again
The integrated value is transmitted to 9. On the other hand, the learning timer unit 18
After clearing the timer value to zero, start counting again. The counter content storage unit 19 that has received the integrated value from the counter unit 17 inputs the time at that time from the clock unit 20, allocates the time to the integrated value, and sequentially (for example, every 30 minutes).
I will remember.

When a predetermined time (for example, 24 hours) has passed, the clock unit 20 outputs a signal for causing the learning unit 21 to output each time stored in the counter content storage unit 19 and the integrated value at each time. After the data is transmitted and the data is transferred from the counter content storage unit 19 to the learning unit 21, the storage is cleared. At the same time, a preset predetermined time (for example, 24 hours later) is reset and the counting is restarted.

The learning section 21 sorts the information from the counter content storage section 19 in descending order based on the integrated value, and allocates the power supply time in order. (For example, within a day, 10 minutes are frequently used, 7 minutes are relatively less frequently, and 5 minutes are less frequently used). By this, the power supply time from what time to what time is determined.

The learning unit 21 causes the next display timer information judging means 22 to adapt the information obtained above to the time pattern (for example, apply it to 24 hours of the next day based on the 24-hour data) and supply the power. Communicate time. The display timer information determining means 22 stores the power supply time and updates it when the power supply time signal from the learning unit 21 is changed. Also, it receives an operation or reception signal from the switch detection means 15 and the appliance operation detection unit 16, and sends a start and restart signal for measuring the power supply time to the next stage.

The display timer section 23 receives the power supply time value from the display timer information judging means 22 at the time of starting the power supply time measurement and at the time of restart, and measures the time. In addition, a power supply signal is sent to the power supply control means 24 during the count, and power supply is stopped at other times. The power control means 24 controls the power supply to the remote control transmission / reception section 12 and the display section 14 based on the signal from the display timer section 23.

As described above, by the functions of the clock unit 20 and the learning unit 21, the time zone in which wireless transmission and reception are frequently required,
It is possible to prevent the consumption of the battery remarkably by distinguishing the time zones other than that in a stepwise manner and reducing the operation time of the remote controller transmission / reception unit 12 and the display unit 14 in the time zones other than that.

[0025]

As is apparent from the above description, in the wireless transmitting / receiving apparatus of the present invention, the learning means determines the usage pattern of the appliance, so that the user can use the wireless device at a high usage frequency according to the usage frequency of the user. The power consumption is reduced by controlling the power supply control unit so that the predetermined time from the time of use until the auto-off function is activated is long, while the predetermined time is shortened during a time of low use frequency. In addition, as a result, the user feels as if there is no auto-off function during times of high frequency of use, which improves the usability of the user.

Therefore, it is possible to prevent the display stop during the auto-off function, which is a conventional problem, from being erroneously determined to be due to a failure or power consumption.
