In the figure, the heat source device 27 is a water heater, and the heat source device 27 is disposed outdoors. The remote control device 1 is a bath remote control device arranged in a bathroom, and the remote control device 1 and the heat source device 27 are signal-connected via two (core) communication lines 50. Although not shown in FIG. 2, the remote control device 2 (see FIG. 4) in the kitchen arrangement is also signal-connected to the heat source device 27 via the two communication lines 50.

  The gas meter 29 is provided in a gas passage 28 connected to the heat source device 27 and has a function of detecting the amount of fuel gas supplied to the heat source device 27. The gas meter 29 has a gas shut-off function that shuts off the supply of fuel gas to the heat source device 27 when a predetermined gas shut-off condition is satisfied. For example, a predetermined seismic intensity (for example, It has a configuration in which fuel gas is shut off by a gas shut-off function when an earthquake of seismic intensity 3) or more occurs or when a gas leak occurs. Further, the gas meter 29 has a gas supply return function for returning the supply of the fuel gas to the heat source device 27 when a manual return operation is performed after the fuel gas supply cutoff by the gas cutoff function.

  For example, as shown in the schematic system configuration diagram of FIG. 4, the heat source device 27 includes burner devices 10 and 16 as heating devices that heat water as a heat medium by combustion of fuel gas, and these burner devices. A gas passage 28 shown in FIG. 2 is connected to the gas pipes 9 and 17 connected to 10 and 16. The burner device 10 is a hot water supply burner device, and the burner device 16 is a reheating burner device. The control device 3 of the heat source device 27 is signal-connected to the remote control device 1 arranged in the bathroom and the remote control device 2 arranged in the kitchen. In the control device 3, an ignition operation is performed on the burner devices 10 and 16, and the burner Combustion control means (not shown in the figure) having a function of igniting and burning the fuel supplied to the devices 10 and 16 and an air supply / exhaust fan (not shown) are provided. .

  The heat source device 27 performs each operation function as described below under the control of the combustion control means based on the operation of the remote control devices 1 and 2. For example, the operation of the hot-water supply function is started by opening a hot-water tap (not shown) provided at the hot-water supply destination of the hot-water supply line 11 with the operation switch of any one of the remote control devices 1 and 2 being on. . This operation is performed by supplying a fuel gas to the hot water supply burner device 10 provided in the combustion section and igniting the fuel gas, and based on the incoming water temperature by the incoming water temperature sensor 6 and the hot water supply amount by the flow rate sensor 4. The hot water supply burner device 10 is combusted (combustion of fuel gas supplied to the hot water supply burner device 10) is performed so that the hot water supply temperature (heated hot water temperature) of 8 becomes the hot water supply set temperature, and passes through the hot water supply heat exchanger 7. Water is heated to create hot water, and hot water is supplied to a hot water supply destination such as a kitchen or bathroom through a hot water supply pipe 11.

The flow rate of the hot water filling is detected by the flow rate sensor 12, and the water level of the bathtub 26 is detected by the water level sensor 20.

  When the hot water filling is completed, the hot water solenoid valve 13 is closed, and when the detected temperature detected by the bath temperature sensor 18 is lower than the hot water filling temperature (bath setting temperature), the operation of the reheating function is performed. In the operation of the reheating function, the circulation pump 21 is driven and hot water in the bathtub 26 is circulated through the recirculation circulation path 25. When the circulation pump 21 is driven, the running water switch 22 is turned on. In FIG. 4, the bath temperature sensor 18 is illustrated as being interposed in the outgoing pipe 24, but the bath temperature sensor 18 may be incorporated in the running water switch 22.

  In the automatic operation, the combustion operation of the reheating burner device 16 is continuously performed so that the temperature of the bathtub hot water does not become lower than the allowable temperature of the bath over the allowable range for a preset time (reheating burner). The operation of the heat retaining function is performed by burning the fuel gas supplied to the apparatus 16. The operation of the chasing function is performed independently when the chasing switch provided in the remote control device 1 is turned on.

  FIG. 1 is a block diagram showing the control configuration of the notification system of this embodiment. As shown in the figure, the remote control device 1 is provided with an earthquake detection means 30, a communication circuit 31, an operation control information setting input means 32, an operation command means 33, and a gas supply return notification means 34.

Note that the remote controller 2 may be provided with the same configuration as the remote controller 1 shown in FIG.

  The reignition operation unit 37 of the heat source device 27 performs an ignition operation on the corresponding burner devices 10 and 16 within a predetermined number of times (for example, 3 times) after the burner devices 10 and 16 are misfired. 10 and 16 are automatically repeated for the number of times until ignition is performed. The reignition operation unit 37 applies an ignition operation execution signal to the combustion control means 38 every time this ignition operation is performed.

  The combustion control means 38 receives the ignition operation execution signal applied from the reignition operation unit 37, and determines whether the corresponding burner devices 10 and 16 are ignited by the ignition operation by the reignition operation unit 37, for example, the burner. It is detected by an appropriate means such as a frame rod sensor (for example, a thermocouple or an optical sensor) provided in the vicinity of the devices 10 and 16, and the detection result (ignition detection signal or ignition non-detection signal) is re-ignition operation unit. 37 and the gas meter cutoff detection means 36.

  When the set number of times is 3, the reignition operation unit 37 first performs the first ignition operation to the corresponding burner devices 10 and 16 after the misfire of the burner devices 10 and 16, as described above. When the corresponding burner devices 10 and 16 are ignited by the first ignition operation (when the combustion control means 38 detects the ignition of the corresponding burner devices 10 and 16), the ignition operation is stopped and the ignition is performed. If there is no ignition (if ignition is not detected by the combustion control means 38 to the corresponding burner device 10, 16), the second ignition operation is performed, and the corresponding burner device 10, 16 is ignited by the second ignition operation. Then stop the ignition operation. In addition, if the corresponding burner devices 10 and 16 are not ignited even in the second ignition operation, the third ignition operation is performed. If the ignition is not performed even in the third ignition operation, the ignition is further performed. The ignition operation is stopped without continuing the operation.

  The gas meter cutoff detection means 36 detects the cutoff of the fuel gas by the gas cutoff function of the gas meter 29. Even if the ignition operation is repeated by the reignition operation unit 37 for the set number of times (for example, three times). When the corresponding burner devices 10 and 16 are not ignited, the ignition non-detection signal of the set number of times is received from the combustion control means 38, and the fuel gas is shut off by the gas shut-off function of the gas meter 29. Is detected.

  When detecting that the gas meter 29 has shut off the fuel gas, the gas meter cutoff detection means 36 adds the detection signal to the communication circuit 35, and notifies the gas supply return via the communication line 50 and the communication circuit 31 of the remote control device 1. Add to 34.

  The gas supply return notification means 34 receives the fuel gas cutoff execution detection signal by the gas cutoff function of the gas meter 29, and the fuel gas supply cutoff information (the fuel gas cutoff cutoff is executed by the gas meter 29 gas cutoff function). Information) and a manual return operation method of the gas meter 29. The notification method is not particularly limited and may be set as appropriate. For example, as shown in FIG. 2, the notification is performed by display on the display screen 49 of the remote control device 1. For example, the gas meter is activated and the gas may have stopped. Check the gas meter. How to reset the gas meter is. , Display its specific method. The gas supply return notifying means 34 may notify at least one of the fuel gas supply cutoff information and the manual return operation method of the gas meter 29.

  Each of the earthquake detection means 30 and 39 detects an earthquake having at least the set seismic intensity (for example, seismic intensity 3) or more, and detects a vibration sensor (mercury switch, mercury switch, bathtub water surface or cistern tank water surface vibration). A water level sensor, a drop sensor), a vibration acceleration watch, and the like. The earthquake detection means 39 applies an earthquake detection signal to the gas meter cutoff detection means 36 when an earthquake is detected. The earthquake detection means 30 adds an earthquake detection signal to the communication circuit 31 when an earthquake is detected, and the communication circuit 31 sends the earthquake detection signal to the communication line 50 when the earthquake detection signal is added from the earthquake detection means 30. In addition to the communication circuit 35, the communication circuit 35 adds the earthquake detection signal to the gas meter cutoff detection means 36.

  The operation control information setting input means 32 is a means for inputting and setting information necessary for the operation of each operation function, that is, for example, information such as a hot water supply set temperature, a bath set temperature, and a bath set water level. The information set by the operation control information setting input means 32 is added to the communication circuit 31 and is added to the combustion control means 38 via the communication circuit 31, the communication line 50, and the communication circuit 35.

  The operation command means 33 is formed by various switches such as an operation switch, an automatic switch, and a follow-up switch. When these switches are operated, the operation command is added to the communication circuit 31, and the communication circuit 31, communication line 50, added to the combustion control means 38 via the communication circuit 35.

  The combustion control means 38 controls the operation of each operation function. As described above, when the ignition operation by the reignition operation unit 37 is performed, the ignition operation is performed to the corresponding burner devices 10 and 16. Detect whether or not the ignition is done. The combustion control means 38 controls the operation of each operation function in accordance with the operation command from the operation command means 33 based on the information set by the operation control information setting input means 32.

  The combustion control means 38 corresponds to the burner device 10 corresponding to the operation of the hot water supply function or the automatic operation or the reheating operation performed in response to the manual operation (automatic switch-on or reheating switch-on) of the remote control device 1. If the ignition to the corresponding burner devices 10 and 16 is not performed even if the ignition operation is repeated for a predetermined set number of times (for example, 3 times), the ignition set number is not set. A detection signal is applied to the gas meter cutoff detection means 36 and immediately after ignition of the corresponding burner device 10, 16 by the ignition operation (after the time when the fuel gas remaining in the introduction part of the corresponding burner device 10, 16 burns). When a misfire occurs, for example, after 3 seconds), a misfire detection signal is applied to the gas meter shutoff detection means 36.

  The gas meter cut-off detection means 36 detects the earthquake of the set seismic intensity or more by at least one of the earthquake detection means 30 and 39 and receives the detection signal. When the misfire detection signal is applied, the execution of the cutoff of the fuel gas by the gas cutoff function of the gas meter 29 is detected. In these cases, the fuel gas cutoff execution detection signal and the earthquake detection signal by the gas cutoff function of the gas meter 29 are added to the communication circuit 35, and these detection signals are transmitted to the communication line 50 and the remote control device 1. This is added to the gas supply return notification means 34 via the circuit 31.

  When the gas supply return notification means 34 receives the fuel gas cutoff execution detection signal and the earthquake detection signal by the gas cutoff function of the gas meter 29, the fuel gas supply cutoff information and the gas meter 29 are substantially the same as described above. In this case, for example, “The gas meter may have been activated due to an earthquake and stopped. Check the gas meter. “The gas meter shuts off the gas due to the earthquake, a display prompting the gas meter to check, and a specific display of the return operation method.

  Further, in the present embodiment, after the manual return operation of the gas meter is completed, for example, during the operation of the hot water supply function or the automatic operation performed in response to the manual operation of the remote control device 1 (automatic switch-on or reheating switch-on) When the combustion control means 38 performs the ignition operation to the corresponding burner devices 10 and 16 during the follow-up operation, and the corresponding burner devices 10 and 16 are ignited, the combustion control means 38 The detection signal is applied to the gas supply return notification means 34 via the communication circuit 35, the communication line 50, and the communication circuit 31 of the remote control device 1.

  The gas supply return notification means 34 receives the ignition detection signal from the combustion control means 38 and cancels the fuel gas supply cutoff information and the return operation method display of the gas meter 29 on the display screen 49. For example, the remote control device 1 is provided with fuel gas supply cut-off information on the display screen 49 and display release operation means (reset button or the like) of the manual return operation method of the gas meter 29 so that the user can perform the return operation of the gas meter 29. When the operation is performed, the display may be canceled by operating the cancellation operation means.

  Next, a description will be given of a second embodiment of the notification system according to the present invention. In the description of the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted or simplified. FIG. 3 schematically shows an arrangement mode example of the heat source device 27, the remote control device 1, and the gas meter 29 in the notification system of the second embodiment. As shown in FIG. 3, in the second embodiment, The heat source device 27 and the gas meter 29 are each connected to an information management device 41 of a centralized management center, and the information management device 41 is provided with a gas meter cutoff detection means 36 and a communication circuit 42.

  Further, the gas meter 29 is provided with an earthquake detection means 40 and a transmission circuit (not shown), and the transmission circuit of the gas meter 20 and the communication circuit 42 of the information management device 41 are connected to a communication line 43, an adapter 44, and an Internet line 45. Connected through. The communication circuit 42 is connected to the communication circuit 35 of the heat source device 27 via the Internet line 46, the adapter 47, and the communication line 48.

In the second embodiment, the gas meter 29 transmits the execution information of the gas shut-off function from the transmission circuit, for example, when the gas shut-off function due to an earthquake or the like is shut off, via the communication line 43, the adapter 44, and the Internet line 45. The information is sent to the information management device 41. The information management device 41 receives the execution information of the gas cutoff function by the communication circuit 42 and adds it to the gas meter gas cutoff detection means 36. Even when a gas shutoff function of the gas meter is performed even in a case other than an earthquake, the gas meter 29 transmits the execution information of the gas shutoff function to the information management device 41, and the information management device 41 performs the execution information of the gas shutoff function. Is added to the gas meter gas cutoff detection means 36. In any case, the gas meter cutoff detection means 36 receives the gas cutoff execution information and detects the fuel gas cutoff execution by the gas cutoff function of the gas meter 29.

  When the gas meter cutoff detection means 36 detects that the fuel gas has been shut off by the gas meter 29, the fuel gas cutoff execution information is sent from the communication circuit 42 of the information management device 41 to the Internet line 46, adapter 47, communication line. 48 to the heat source device 27. The heat source device 27 receives the fuel gas cutoff execution information by the communication circuit 35 and transmits it to the communication circuit 31 of the remote control device 1 through the communication line 50 as in the first embodiment. The gas supply return notification means 34 notifies the fuel gas supply cutoff information and the manual return operation method of the gas meter 29.

The fuel gas supply cutoff information by the gas supply return notification means 34 and the notification of the manual return operation method of the gas meter 29 are performed when the fuel gas cutoff execution information is added from the information management device 41 to the heat source device 27. However, in the second embodiment, it is performed at the following timing. That is, the gas meter shutoff detection means 36 of the heat source device 27 stores the information when the fuel gas shutoff execution information is added from the information management device 41, and when the operation of the hot water supply function is started thereafter, or the remote control device 1 is transmitted to the gas supply return notifying means 34 when the automatic switch-on or the renewal switch-on by manual operation 1 is performed, the fuel gas supply cutoff information and the gas meter 29 are transmitted. The manual return operation method is displayed on the display screen 49. In this way, the user can easily notice these displays.

  In addition, the transmission circuit of the gas meter 29 transmits a signal for distinguishing between when the gas meter 29 performs the fuel gas cutoff function due to an earthquake and when the gas meter 29 performs the fuel gas cutoff function for reasons other than the earthquake. (For example, when an earthquake is detected, an earthquake detection signal is transmitted together.) When the gas meter 29 performs the function of shutting off the fuel gas due to an earthquake, the supply of fuel gas by the gas supply return notification means 34 is performed. When the shut-off information is displayed, as shown in FIG. 3, it may be displayed that “the gas meter may have been stopped due to an earthquake”, or the above-mentioned signal for distinguishing is not transmitted. In addition, the display may not be “operated due to an earthquake” but may be displayed as “the gas meter may have been activated and stopped”.

  In the second embodiment, after the return operation of the gas meter 29 is performed, the transmission circuit of the gas meter 29 transmits the gas supply return information to the information management device 41 of the central management center. The information management device 41 receives the gas supply return information by the communication circuit 42 and transmits the information from the communication circuit 42 to the heat source device 27 via the Internet line 46, the adapter 47, and the communication line 48. The heat source device 27 receives the gas supply return information by the communication circuit 35 and transmits it to the communication circuit 31 of the remote control device 1 via the communication line 50, and the remote control device 1 displays the display screen 49 by the gas supply return notification means 34. The fuel gas supply cutoff information and the return operation method display of the gas meter 29 are canceled.

  In addition, this invention can take various embodiment, without being limited to the said Example.
