[0015]
【Example】
Hereinafter, an embodiment of a controller for a hot water heater of the present invention will be described with reference to the drawings.
[0016]
FIG. 1 is a configuration diagram of a hot water supply controller as one embodiment of the present invention, and FIG. 2 is an internal circuit diagram thereof.
[0017]
As shown in FIG. 1, the control device of the present invention comprises a first wireless remote controller 1, a second wireless remote controller 2, and a communication unit 3 (of course, three or more wireless remote controllers are possible). The unit 3 is attached to the instrument 4 and is connected to the main body control unit 5 for controlling the operation of the instrument 4 in the instrument body, and storing / counting the temperature that has been used so far and the number of times each temperature is used. ing. In addition, the first wireless remote controller 1 and the second wireless remote controller 2 are each provided with operation units 6 and 7 for inputting and operating an instruction signal to the instrument 4, and a notification unit 8 for displaying the setting state, operation state and operation contents of the instrument. , 9 are provided.
[0018]
As shown in FIG. 2, the first wireless remote controller 1 and the second wireless remote controller 2 have the same circuit configuration. Each has ICs 10 and 11 for controlling the operation of the remote controller. The ICs 10 and 11 control the wireless transmission / reception units 14 and 15 that are converters of electric signals and radio wave signals, receive signals from the operation units 6 and 7, and output signals to the notification units 8 and 9.
[0019]
Further, the communication unit 3 has an IC 16 that transmits and receives signals to and from the main body control unit 5 and a wireless transmission / reception unit 17 (the same as that incorporated in the first wireless remote control 1 and the second wireless remote control 2). Control part 17.
[0020]
Next, the operation in the above configuration will be described. When communication is performed from the communication unit 3 toward the first wireless remote controller 1 and the second wireless remote controller 2, when there is no response to the communication, the communication unit has a retry function and performs a certain number of communication retries. However, if there is no response from the wireless remote controller within a certain number of times, the IC 16 of the communication unit 3 determines that the first wireless remote controller 1 and the second wireless remote controller 2 cannot communicate.
[0021]
At this time, the IC 16 outputs a hot water supply set temperature of the appliance 4, and the IC 16 outputs a change signal to the temperature of the preprogrammed condition to the main body control unit 5. The appliance 4 is controlled so as to be pulled out from the memory in the main body control unit 5 and to change the hot water supply set temperature.
[0022]
The temperature of the condition programmed here is the temperature of the last memory used immediately before the communication error, the temperature most frequently used, the lowest temperature used, or the like. Further, the temperature memory may be stored by other than the main body control unit 5.
[0023]
As described above, according to the present embodiment, when all of the wireless remote controllers have communication errors, the hot water supply set temperature can be changed to the stored arbitrary temperature and the operation can be continued. Safety can be improved.
[0024]
【The invention's effect】
As is apparent from the above description, the control device for a hot water heater according to claim 1 according to the present invention stores the hot water supply set temperature in an arbitrary memory stored in the appliance main body control unit when all remote controllers have communication errors. By changing and continuing operation, the water heater can be used even when there is a communication error.
[0025]
Further, in claim 2, when all remote controllers have communication errors, the hot water supply temperature does not change by changing the hot water supply set temperature to the last memory of the remote controller which has priority immediately before the communication error. Use can be continued without a sense of incongruity, and usability can be improved.
[0026]
Further, in claim 3, when a communication error occurs in all of the remote controllers, the hot water supply set temperature is changed to the temperature that has been used most frequently at the stored temperature, so that the remote controller can be used at the temperature most required by the user. It can be continued and usability can be improved.
[0027]
Furthermore, in claim 4, when all the remote controllers have communication errors, the lowest temperature that the user has used so far is changed by changing the hot water supply set temperature to the lowest stored temperature. Can be used continuously, and safety can be secured.
