It is characterized by.

  According to the present invention, an electrical device is connected to a commercial power source via a switch circuit, and the electrical device is connected to a power source circuit connected to the switch circuit and a signal connected to the electrical device via a communication line. A latch relay circuit that operates the switch circuit in response to a signal applied from the operation device side to the switch circuit side and connects and disconnects the commercial power supply and the power supply circuit of the electrical device. When a simple operation such as power-off operation of the electric device is performed by the power switch, a power-off operation signal is applied to the latch relay circuit of the electric device via the communication line, and the commercial power source of the electric device is transmitted by the latch relay circuit. The standby power of the electric device can be reduced to zero by cutting off the connection with. Note that whether or not the connection between the commercial power supply and the power supply circuit of the electric device is cut off is detected by a power cut-off detection circuit.

  In the operating device, when the electric device is connected to the commercial power source, the power of the commercial power source is charged to the battery power source of the operating device via the power circuit and the communication line of the electric device. When the electrical device is turned on by the power switch of the operating device while the connection with the commercial power source of the electrical device is interrupted, the power recovery circuit supplies power from the battery power source to the electrical device and latch latch Since the circuit is operated and the connection with the commercial power source of the electrical device is restored, the connection with the commercial power source of the electrical device is interrupted by the power-off operation of the electrical device with the power switch, and the power source is turned on at the electrical device side. Even in the blocked state, the connection between the electric device and the commercial power source can be restored when the power is turned on by the power switch of the operating device. Then, the electric device can be operated by electric power from the commercial power source and can start an appropriate operation.

  In addition, when the connection between the electrical equipment and the commercial power supply is cut off, the battery power of the operating device gradually decreases in charge, but the operating device is provided with a voltage detection circuit that detects the voltage of the battery power supply. When the voltage of the battery power detected by the voltage detecting means falls below a predetermined set value while the connection with the commercial power source of the electric equipment is cut off, the power from the battery power is reduced by the power recovery circuit. Since the connection to the commercial power source of the electrical device is restored by supplying the electrical device to operate the latch relay circuit, the battery power source can be charged again from the commercial power source by this connection restoration.

  Therefore, for example, when the charging is sufficiently performed, a power-off operation signal is again applied from the operating device to the latch relay circuit of the electric device via the communication line, and the power circuit and the commercial power source of the electric device are connected by the latch relay circuit. After that, when the voltage of the battery power detected by the voltage detecting means again falls below a predetermined set value, the power supply return circuit disconnects the battery power from the operating device as described above. Even if the power switch continues to be off for a long time by repeating the operation of operating the latch relay circuit with electric power to restore the connection of the electrical equipment to the commercial power supply, Charging is maintained.

Further, since the standby power can be reduced to zero by disconnecting the connection between the electric device and the commercial power source when the battery power supply is not being charged while the power switch is off, the standby power can be significantly reduced.

  In addition, the electrical device and the operation device are signal-connected via two communication lines, but usually the polarity of the communication line connection part on the heat source side is not known (the communication line is connected to the electrical device). Therefore, the polarities of the two connection terminals provided in the electric device are determined at the time of the laying work and vary depending on the laying of the electric device). Therefore, the polarity discriminating circuit for discriminating the polarity of the communication line connection part on the electric device side in the operating device, and the polarity of the electric power supplied to the electric device side through the communication line according to the polarity discriminated by the polarity discriminating circuit are switched. A polarity switching circuit is provided, the polarity switching circuit switches the polarity according to the polarity determined by the polarity determination circuit, and the power supply return circuit supplies power from the battery power source of the operating device to the electric device, thereby supplying power. The operation can be performed without hindrance, and the above effects can be exhibited.

  Further, a function of supplying power from a battery power source to the electric device at a predetermined setting time and disconnecting the electric device from the commercial power source during disconnection from the commercial power source of the electric device; By providing at least one of the functions of supplying power from a battery power source to the electrical device every time a predetermined set period has elapsed and restoring the connection with the commercial power source of the electrical device, The following effects can be achieved.

  For example, some electrical devices are connected to a central management center in signal, and have a function of transmitting data such as energy usage of the electrical devices to the central management center. For example, this data transmission is performed every day at 12:00. In some cases, data transmission is determined to be performed at a set time. In such an electrical device, if the connection with the commercial power source of the electrical device is cut off at the set time with the power switch of the operating device being off, data transmission to the central management center cannot be performed. As described above, by supplying power from the battery power source to the electric device at each set time and returning the connection of the electric device to the commercial power source, data transmission to the central control center at each set time It can be performed.

  In addition, depending on the installation location of the electrical equipment, there is a device (for example, a heat source device) for performing winter freezing prevention operation of the water in the pipeline in the electrical equipment or the water in the pipeline connected to the electrical equipment. In such an apparatus, it is necessary to perform antifreeze heater operation control and confirmation operation. In such an apparatus, the electric power from the battery power source is supplied to the electric device every time a predetermined set period elapses, and the connection with the commercial power source of the electric device is restored, so that the antifreeze heater operation control or The confirmation operation can be performed without any trouble. In such an anti-freezing operation device, for example, an electrical device is provided with means for detecting the outside air temperature, and the set period is set when the temperature is low based on the temperature detected by the outside air temperature detecting means. When the outside temperature is high, the set period may be lengthened.

  Furthermore, by forming the power switch as a switch that also serves as an operation switch for operating on / off of the electric device, the operation device can be simplified and the cost of the operation system can be reduced.

  Furthermore, by providing a return switch for turning on the switch circuit by manual switch operation to restore the connection between the power circuit of the electrical device and the commercial power supply, the latch relay circuit can be operated even when the power switch is turned off. Even if a power failure occurs when the switch circuit is turned off and the connection between the commercial power supply and the power supply circuit of the electrical equipment is interrupted, and the battery power of the operating device is no longer charged when the switch circuit is off, the return switch Thus, the connection between the power supply circuit of the electric device and the commercial power supply can be restored. Therefore, even if a situation such as a power failure occurs, it is possible to provide a system that can operate the electrical equipment without any problem.

  The polarity switching circuit 17 has four transistors 19 to 22. The transistors 19 and 21 are on the plus (+) side of the battery power supply 14, and the transistors 20 and 22 are on the minus (−) side of the battery power supply 14. Are connected to each. The transistors 19 and 20 are connected to the microcomputer 12 via the wiring (A), and the transistors 21 and 22 are connected to the microcomputer 12 via the wiring (B).

  The communication circuit 13 of the remote control device 1 is a circuit that transmits and receives signals to and from the heat source device 27 (the communication circuit 8 thereof) via the communication line 2. The operation switch 35 functions as a power switch for operating the connection and disconnection of the power source circuit 5 of the heat source unit 27 and the commercial power source 3 by applying an operation signal to the latch relay circuit 9 of the heat source unit 27, and the heat source unit 27 also has a function of operating on / off of operation. The battery power supply 14 has a function of charging the power of the commercial power supply 3 from the power supply circuit 5 through the communication line 2 when the power supply circuit 5 of the heat source device 27 is connected to the commercial power supply 3. The voltage detection circuit 15 is a circuit that detects the voltage of the battery power supply 14.

  The polarity discriminating circuit 16 is a circuit that discriminates the polarities of the communication line connecting portions 30 and 31 on the heat source unit 27 side. The polarity switching circuit 17 is a circuit that switches the polarity of the electric power supplied to the heat source unit 27 through the communication line 2 in accordance with the polarity determined by the polarity determination circuit 16. The display unit 18 displays an on / off indication of the operation switch 35 by an LED (light emitting diode), and the LED is turned on when the operation switch 35 is on, and the LED is turned off when the operation switch 35 is off.

  One of the characteristic configurations in the present embodiment is that when the power source 27 is turned off by the operation switch 35 of the remote controller 1, the power off operation signal is transmitted via the communication line 2 to the remote controller. In addition to the latch relay circuit 9 of the heat source unit 27, the standby power of the heat source unit 27 is made zero by cutting off the connection between the power source circuit 5 of the heat source unit 27 and the commercial power source 3 by the latch relay circuit 9. It is. That is, in the present embodiment, like the conventional heat source unit 27, the operation switch 35 of the remote control device 1 is not performed without performing the operation of unplugging the electric plug of the heat source unit 27 body from the outlet or turning off the mechanical switch. The standby power of the heat source unit 27 can be made zero only by the power off operation (operation off operation).

  In addition, the second characteristic configuration in the present embodiment is that the operation of the remote control device 1 is performed while the connection between the power source circuit 5 of the heat source unit 27 and the commercial power source 3 is turned off by the power-off operation of the operation switch 35 of the remote control device 1. When the power source operation of the heat source device 27 by the switch 35 is performed and when the voltage of the battery power source 14 detected by the voltage detection means 15 of the remote control device 1 falls below a predetermined set value, the microcomputer 12 A power supply return circuit having a function of supplying power from the battery power supply 14 to the heat source device 27 via the communication line 2 and returning the connection between the power supply circuit 5 of the heat source device 27 and the commercial power supply 3 by control. This power supply recovery circuit includes a battery power supply 14 and a microcomputer 12.

  The power supply from the battery power supply 14 to the heat source unit 27 by the power supply return circuit is performed by the polarity switching circuit 17 by switching the polarity according to the polarity determined by the polarity determination circuit 16. In the example, the power recovery circuit also includes the polarity switching circuit 17. That is, in the present embodiment, the power recovery circuit switches the polarity of the power sent from the communication line connection units 32 and 33 to the communication line 2 according to the polarity of the communication line connection units 30 and 31 by the polarity switching circuit 17. The electric power from the battery power source 14 is supplied to the heat source unit 27 via the communication line 2, and the latch relay circuit 9 is operated by the electric power to turn on the switch circuit 4.

  The polarity switching operation by the polarity switching circuit 17 is performed as follows. For example, when the polarity on the communication line connection unit 30 side is plus (+) and the polarity on the communication line connection unit 31 side is minus (−), as shown in FIG. Then, by turning on the transistors 19 and 20 via the wiring (A) (transistors 21 and 22 are off), the communication line 2a side is positive, and the communication line 2b side is negative. On the other hand, when the polarity on the communication line connection part 30 side is negative and the polarity on the communication line connection part 31 side is positive, as shown in FIG. By turning on the transistors 21 and 22 through the transistors (transistors 19 and 20 are off), the communication line 2a side is negative, and the communication line 2b side is positive.

In the present embodiment, in addition to the function as described above, the power recovery circuit is connected from the battery power source 14 of the remote control device 1 at a predetermined set time while the connection of the heat source unit 27 to the commercial power source 3 is interrupted. Is supplied to the heat source unit 27 to restore the connection of the heat source unit 27 with the commercial power source 3. In other words, the microcomputer 12 is provided with a clock mechanism. When the time detected by the clock mechanism reaches a set time (for example, 12:00), the power supply return circuit is connected from the battery power supply 14 to the heat source device 27 in the same manner as described above. Is connected to the commercial power supply 3 of the heat source unit 27.

  By doing in this way, even if the connection with the commercial power source of the heat source device 27 is interrupted by the turning-off operation of the operation switch 35, the power from the battery power source 14 to the heat source device 27 by the power recovery circuit every day, for example, at 12:00. Since the supply is performed and the connection of the heat source unit 27 to the commercial power source 3 is restored, for example, data such as the energy usage amount of the heat source unit 27 is transferred to the centralized management center connected to the heat source unit 27 via the adapter. Can be sent.

  In addition, the power recovery circuit is connected from the battery power supply 4 of the remote control device 1 every predetermined time period from the reference time (for example, when the heat source device 27 is installed) while the connection of the heat source device 27 to the commercial power source 3 is cut off. Is supplied to the heat source unit 27 to restore the connection of the heat source unit 27 with the commercial power source 3. That is, based on the detection signal of the thermistor 23, the temperature detection circuit 10 detects the outside air temperature in the region where the heat source unit 27 is disposed, and the outside air temperature is set to a set threshold temperature (for example, 7 for example) according to this detected temperature (outside air temperature). In winter when the temperature is lower than ° C.) and there is a risk of freezing of water pipes such as water supply, hot water supply and reheating, the set period is set as short as 30 seconds, and the outside temperature is higher than the set threshold temperature and When there is no risk of freezing, the setting period is set to be long, such as 1 day or 7 days. Then, every time this set period elapses, the power return circuit supplies power from the battery power source 14 to the heat source unit 27 and restores the connection of the heat source unit 27 to the commercial power source 3 in the same manner as described above.

  By doing in this way, even if the connection with the commercial power source 3 of the heat source unit 27 is cut off by the turning-off operation of the operation switch 35, the battery power source 14 to the heat source unit 27 by the power supply return circuit at an appropriate timing. The power supply is performed and the connection of the heat source device 27 to the commercial power source 3 is restored, and the operation and operation check of the anti-freezing heater are performed, and it is possible to prevent the freezing of the pipeline such as water supply, hot water supply and reheating. . The setting method of the set period is not particularly limited and is set as appropriate. For example, the thermistor 23 is omitted, and the set period is set short only during the winter season detected by the microcomputer 7. Control may be performed such that the connection of the machine 27 with the commercial power supply 3 is restored, and the connection with the commercial power supply 3 of the heat source machine 27 is restored by setting a longer setting period in other seasons.

The present embodiment is configured as described above. For example, the standby power cut-off device proposed in Patent Document 1 includes an electrical device connected to a commercial power source and a remote control device wirelessly connected to the device. Both battery power sources are built in, both battery power sources are charged, the connection between the commercial power source and the power supply circuit is cut off when the power switch is off, and the electrical equipment is turned on in response to the start operation signal from the remote control device. In contrast to the operation using the electric power of the battery power source of the electrical equipment, the present embodiment utilizes the fact that the heat source device 27 and the remote control device 1 are connected via the two communication lines 2. A simple configuration in which the battery power source 14 is provided only on one side can have the characteristic configuration as described above in which the power of the battery power source 14 is used for power recovery on the heat source device 27 side.

  FIG. 3 shows an example of an operation flow in the present embodiment. As indicated by an arrow in the range A in FIG. 5, the heat source device 27 and the remote control device 1 are connected via the communication line 2 by the communication circuits 8 and 13 when the main body of the heat source device 27 (electric device) is turned on. Remote control communication is performed. Based on this communication, for example, if the heat source device 27 has a hot water supply function, the hot water supply set in the remote control device 1 when the hot water tap is opened with the operation switch 35 of the remote control device 1 turned on. Combustion control of the burner device provided in the heat source unit 27 is performed so that hot water at the set temperature can be discharged. Further, when the heat source device 27 has an automatic hot water filling function for the bathtub, when the automatic switch for bath hot water is turned on from the remote control device 1, the automatic switch on signal is It is added to the communication circuit 8 of the heat source unit 27 from the communication circuit 13 of the apparatus 1 via the communication line 2, and the heat source unit 27 performs a filling operation control for filling the bathtub.

  Note that the operation of the heat source unit 27 and the communication operation between the heat source unit 27 and the remote control device 1 are set as appropriate, but these operations are well known and will not be described in detail.

  When the operation switch (SW) 35 of the remote control device 1 is turned off (operation off operation) by the user (when the operation switch 35 is on), the operation switch 35 is manually set. When pressed, as shown by an arrow R1 in FIG. 3, operation-off information (operation ON bit = 0 signal) is transmitted from the communication circuit 13 of the remote control device 1 to the communication circuit 8 of the heat source device 27. . In the present embodiment, the operation off signal (operation off information) is also used as a power off signal for cutting off the connection of the heat source unit 27 with the commercial power source 3, so the operation off information from the remote control device 1 is the heat source unit. 27, the heat source unit 27 operates the latch relay circuit 9 to turn off the switch circuit 4, and disconnects the power supply connection to the power supply circuit 5 and a load (not shown) and the commercial power supply 3 ( AC100V cut off). By this operation, the standby power of the heat source unit 27 becomes zero. As described above, the “operation-off information” is sent from the remote control device 1 to the heat source device 27. However, since the heat source device 27 turns off the power by the signal, the operation-off signal is substantially meaningless. However, this is done to ensure consistency with the ON signal.

  Further, if the connection between the power supply circuit 5 and the commercial power supply 3 is cut off in this way, the circuit on the heat source unit 27 side cannot be operated as it is, so that at this time, the power from the battery power supply 14 of the remote control device 1 Is supplied to the heat source unit 27. Then, the power cutoff detection circuit 11 detects whether or not the connection between the power supply circuit 5 and the commercial power supply 3 is cut off, and if it is detected that the connection between the power supply circuit 5 and the commercial power supply 3 is cut off, As shown by the arrow N1, power-off information (AC100V cutoff bit = 1 signal) is transmitted from the heat source device 27 to the remote control device 1. When receiving the power-off information from the heat source device 27, the remote control device 1 stops the power supply to the heat source device 27, and stops the operation of the LED by turning off the LED of the display unit 18 of the remote control device 1. Is displayed.

  Thereafter, the circuit operation of the heat source device 27 is stopped (that is, communication with the remote control device 1 cannot be performed), and the circuit portion of the remote control device 1 (communication circuit 13, microcomputer 12, In a state where only the operation switch 35, the display unit 18, the battery power supply 14, and the voltage detection circuit 15) are operable, the apparatus waits until the operation switch 35 is turned on.

  During this standby, when the voltage detection circuit 15 of the remote control device 1 detects that the voltage of the battery power supply 14 has dropped below the set value, the power supply recovery circuit first starts the heat source from the battery power supply 14. The power supply to the machine 27 is started via the communication line 2 (with the polarity matched to the polarity of the communication line connection parts 30 and 31 by switching by the polarity switching circuit 17), and the communication circuit 8 of the heat source machine 27 is activated. Enable (return of remote control communication).

  Then, the heat source unit 27 transmits a remote control communication return confirmation signal to the remote control device 1 as indicated by an arrow N2. When receiving the confirmation signal, the remote control device 1 transmits a request (charge request bit = 1) for charging the battery power supply 14 of the remote control device 1 to activate the latch relay circuit 9 as indicated by an arrow R2. Then, the switch circuit 4 is turned on, and the connection between the power source circuit 5 of the heat source unit 27 and the commercial power source 3 is restored. Then, as shown by an arrow N3, a charge start signal is transmitted from the heat source device 27 to the remote control device 1, and the battery power supply 14 of the remote control device 1 uses the power of the commercial power supply 3 to the power supply circuit 5 and the communication line 2. Start charging.

  When the charging of the battery power supply 14 is completed, the remote control device 1 transmits a charge request stop request (charge request bit = 0) to the heat source unit 27 as indicated by an arrow R3 in FIG. In response to this signal, the heat source unit 27 operates the latch relay circuit 9 to turn off the switch circuit 4 and disconnects the connection between the power source circuit 5 and the commercial power source 3. When the power cut-off detection circuit 11 detects the cut-off of the connection between the power supply circuit 5 and the commercial power supply 3 by the power from the power supply 14, as shown by the arrow N4, the power-off information (AC100V cut-off bit = 1 signal) is sent to the remote control device. 1 to send.

  When receiving the power-off information from the heat source device 27, the remote control device 1 stops the power supply to the heat source device 27. As a result, the circuit operation of the heat source device 27 is stopped and waits until the operation switch 35 is turned on again. Further, during this standby, when the voltage detection circuit 15 of the remote control device 1 detects that the voltage of the battery power supply 14 has dropped below the set value, the same operation as described above is repeated.

  When the operation switch (SW) 35 is turned on, power supply from the battery power source 14 to the heat source unit 27 is started via the communication line 2 in the same manner as described above, and the communication of the heat source unit 27 is performed. The circuit 8 is enabled (return of remote control communication), and a remote control communication return confirmation signal is transmitted from the heat source device 27 to the remote control device 1 as indicated by an arrow N5. When receiving the confirmation signal, the remote control device 1 transmits a signal of operation ON bit = 1 (a signal that is an ON request bit of the power supply circuit 5 and includes an operation ON request) as indicated by an arrow R4, The latch relay circuit 9 is actuated to turn on the switch circuit 4, and the connection between the power source circuit 5 of the heat source unit 27 and the commercial power source 3 is restored. Then, as shown by an arrow N6, since a confirmation signal for AC 100V return is transmitted from the heat source device 27 to the remote control device 1, the power supply from the remote control device 1 to the heat source device 27 is stopped, and the LED of the display unit 18 is turned on. To indicate that the operation is on. Thereafter, remote control communication is continued.

Further, as shown in FIG. 4A, when a predetermined set time (for example, 12:00) is reached while the heat source device 27 is disconnected from the commercial power source 3, the battery power source 14 of the remote control device 1 is used. Is supplied to the heat source device 27, the communication circuit 8 of the heat source device 27 is enabled, and a confirmation signal for returning the remote control communication is transmitted from the heat source device 27 to the remote control device 1 as indicated by an arrow N7 in FIG. When receiving the confirmation signal, the remote control device 1 transmits a signal of power ON bit = 1 (ON request bit of the power supply circuit 5) as shown by an arrow R5, and operates the latch relay circuit 9 to switch The circuit 4 is turned on, and the connection between the power supply circuit 5 of the heat source device 27 and the commercial power supply 3 is restored. As indicated by an arrow N8, the heat source device 27 transmits this connection return confirmation signal to the remote control device 1, and the remote control device 1 receives this confirmation signal and stops supplying power to the heat source device 27 (note that In this case, the LED lighting of the display unit 18 may remain stopped (turned off)).

  Then, when data transmission from the heat source device 27 to the central management center is performed, for example, by the connection restoration of the power source circuit 5 of the heat source device 27 and the commercial power source 3, a confirmation signal is transmitted from the heat source device 27 to the remote control device 1. In response to the confirmation signal, the remote control device 1 transmits an end signal to the heat source device 27 side, operates the latch relay circuit 9 again to turn off the switch circuit 4, and connects the power supply circuit 5 and the commercial power supply 3 to each other. Cut off. After this connection is cut off, the same operation as described above is performed.

Further, as shown in FIG. 4 (b), the electric power from the battery power source 14 of the remote control device 1 every time a predetermined set period elapses from the reference time while the connection of the heat source device 27 to the commercial power source 3 is cut off. To the heat source unit 27, the communication circuit 8 of the heat source unit 27 is operable, and a confirmation signal for returning the remote control communication is transmitted from the heat source unit 27 to the remote control device 1 as indicated by an arrow N11 in FIG. When receiving the confirmation signal, the remote control device 1 transmits a signal of power ON bit = 1 (ON request bit of the power supply circuit 5) as shown by an arrow R11, and operates the latch relay circuit 9 to switch The circuit 4 is turned on, and the connection between the power supply circuit 5 of the heat source device 27 and the commercial power supply 3 is restored. As indicated by an arrow N12, the heat source device 27 transmits this connection return confirmation signal to the remote control device 1, and the remote control device 1 receives this confirmation signal and stops supplying power to the heat source device 27 (note that In this case as well, the LED lighting of the display unit 18 may remain stopped (turned off)).

  Then, when the operation and operation check of the anti-freezing heater are performed, for example, when the connection between the power supply circuit 5 of the heat source device 27 and the commercial power source 3 is restored, the confirmation signal is transmitted from the heat source device 27 to the remote controller after the operation stop or operation check. The latch relay circuit 9 is actuated again in response to the end signal from the remote control device 1 and the switch circuit 4 is turned off, and the connection between the power supply circuit 5 and the commercial power supply 3 is cut off. After this connection is cut off, the same operation as described above is performed.

For example, in the above-described embodiment, the charging request bit = 1 is transmitted by the arrow R2 in FIG. 3, the operation ON bit = 1 is transmitted by the arrow R4 in FIG. 3, and the charging request bit is distinguished from the operation ON bit. However, these are all signals that restore the connection between the power supply circuit 5 and the commercial power supply 3 of the heat source unit 27 (returning the connection between the power supply circuit 5 and the commercial power supply 3, In order to be able to charge the battery power source 14 of the remote control device 1 or to make the heat source unit 27 operable), in any case, the power ON bit = 1 without any distinction as described above A signal (ON bit of the power supply circuit 5) may be used and the operation ON bit = 1 (operation ON information) may be transmitted separately. Similarly, the operation ON bit = 0 is transmitted at the arrow R1 in FIG. 3 and the charge request bit = 0 is transmitted at the arrow R3 in FIG. Since the signal remains the same as the signal that cuts off the connection between the circuit 5 and the commercial power supply 3, the power ON bit = 0 signal (off bit of the power supply circuit 5) is used without any discrimination as described above. The operation ON bit = 0 (operation OFF information) may be transmitted separately.
