In addition, for example, when the heat source device has an automatic hot water filling function to the bathtub, it is equipped with a function to send a voice guidance such as “The bath has boiled” from the remote control device when the hot water filling is finished. Remote control devices have also been put into practical use. Thus, when voice guidance is transmitted from the remote control device, it is possible to know the timing of bathing and to prompt the user to take a comfortable bath (see, for example, Patent Document 1).

  By the way, in recent years, an emergency earthquake bulletin distribution system as shown in FIG. 11 has been proposed and partly put into practical use. Earthquake early warnings immediately after the occurrence of an earthquake, analyze the observation data captured by a seismometer close to the epicenter and immediately estimate the epicenter and magnitude of the earthquake (magnitude), and based on this, the arrival time of the main motion in each location It is information that estimates the seismic intensity and informs as quickly as possible. This information is transmitted from the Japan Meteorological Agency 60 as shown in FIG. The earthquake early warning is received by a receiver 64 or a television (not shown) installed indoors, such as a broadcasting station, via a distribution company 61 such as REIC (Earthquake Early News Communication Council). Is done.

  The receiver 64 is provided in a place having public property that is required to quickly receive and deal with an earthquake early warning, such as a railway-related company, a government office, in addition to a broadcasting station. Recently, it has been considered to install the receiver 64 in a management room of an apartment house such as an apartment, and there are some places where it is actually installed. Then, considering the case where the residents of each house need to evacuate from the housing complex, such as a condominium, when a large earthquake occurs, when the receiver 64 receives the earthquake early warning, For example, it has been proposed to add to the intercom of each house by centralized management of the management room.

  Furthermore, a remote control device provided in a bathroom or kitchen for remote operation of a heat source device such as a water heater is provided with a function of detecting reception of an earthquake early warning via a receiver 64 and an interphone. Some proposals have been made to notify the upcoming earthquake.

(BGM) is also transmitted. These dial tone levels can be changed by volume setting operation means (not shown).

  FIG. 5 shows an external configuration of the kitchen remote control device 2. In this kitchen remote control device 2, the same reference numerals are given to the same components as those in the bath remote control device 1, and the description of the kitchen remote control device 2 will not be repeated with the description of the bath remote control device 1. In the kitchen remote control device 2, the reheating switch 33 and the bath water temperature and water level setting switches are omitted from the bath remote control device 1, and the up switch 70 marked with “△” and the down switch marked with “▽”. 71 is provided. In this example, since the display screen 32 is small, the kitchen remote controller 2 is configured to display a code such as “Eq” shown in FIG.

  The bath remote controller 1 or the kitchen remote controller 2 can be used to remotely control each operation function of the water heater 27 as shown in FIG. That is, by turning on the operation switch 35 of any one of the remote control devices 1 and 2 and opening a hot water tap (not shown) provided at the hot water supply destination of the hot water supply pipe 11 in this state, the operation of the hot water supply function is performed. Be started. This operation is based on the incoming water temperature by the incoming water temperature sensor 6 and the amount of hot water supplied by the flow sensor 4, and the hot water supply burner 10 is burned so that the hot water supply temperature (hot water temperature) by the hot water temperature sensor 8 becomes the hot water supply set temperature. The water passing through the heat exchanger 7 is heated to produce hot water, and the hot water is supplied to a hot water supply destination such as a kitchen or bathroom through a hot water supply pipe 11.

  The automatic operation of the hot water heater 27 is a continuous operation of the hot water filling function, the reheating function, and the heat retention function. The automatic switch 36 is turned on while the operation switch 35 is turned on. The hot water solenoid valve 13 is opened, and hot water heated through the hot water supply heat exchanger 7 enters the hot water supply line 14 from the hot water supply line 11 in the same manner as the operation of the hot water supply function. Then, it is dropped into the bathtub 26 through a recirculation circuit 25 having a return pipe 23 and an outgoing pipe 24.

  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. The operation of the chasing function is also performed when the chasing switch 33 is pressed. The operation of the reheating function is such that the circulating pump 21 is driven and hot water in the bathtub 26 is circulated through the recirculation circuit 25. In the operation of the automatic operation, the operation of the heat retaining function is continuously performed so that the temperature of the bathtub hot water does not become lower than the allowable temperature of the bath beyond the allowable range for a preset time.

  In FIG. 10, 12 is a flow sensor, 22 is a water flow switch, 19 is a conduit for connecting the discharge port of the circulation pump 21 and the water intake of the reheating heat exchanger 15, and 17 is a gas passage to the bath burner 16. , 49 indicate water quantity control valves, respectively.

  Further, the bath remote control device 1 and the kitchen remote control device 2 applied to the emergency earthquake warning transmission / reception system of the present embodiment have a control configuration related to the emergency earthquake warning shown in FIG. 1 in addition to the combustion control configuration as described above. ing. That is, each of the remote control devices 1 and 2 includes an emergency earthquake warning receiving unit 40, an earthquake early warning notification unit 41, an earthquake intensity information determination unit 42, an instruction operation reception control unit 43, an earthquake information storage unit 44, a display control unit 45, and a clock mechanism 51. The earthquake early warning related control unit 20 includes an alarm setting unit 31, a speaker 34, an operation instruction operating unit 37, an operation switch 35, a display operating unit 46, a lamp 39, and a display. It is connected to the screen 32 and the earthquake early warning history deletion operation unit 47.

  As shown in FIG. 2, the kitchen remote control device 2 is electrically connected to the intercom 62 of each house 69 in an apartment or the like via communication lines 65 and 66 and a terminal 63. The bath remote control device 1 is also electrically connected to the intercom 62 via the water heater 27, the communication lines 65, 66, 67, 68, the terminal 63, and the kitchen remote control device 2. And the system which adds the earthquake early warning which the receiver 64 received to the remote control apparatuses 1 and 2 via the intercom 62 is formed.

  As shown in FIG. 1, the interphone 62 has a signal transmission control unit 30. The signal transmission control unit 30 is at least one of a waveform and a length of a signal transmitted to the remote control devices 1 and 2 side. Is variably set according to the seismic intensity information of the earthquake early warning.

  For example, FIG. 6 shows an example of a signal transmitted by the signal transmission control unit 30 toward the kitchen remote control device 2 side. The signal transmission control unit 30 responds to the seismic intensity information of the emergency earthquake bulletin, for example, as shown in FIGS. 6A to 6D, the signal waveform immediately after the signal transmission (for example, for 0.1 seconds from the start of signal transmission). Or change the signal length as shown in FIGS. 6 (e) and 6 (f). When the earthquake early warning is continuously transmitted, as shown in FIG. 6G, a signal is transmitted in the manner of interrupting the seismic intensity information of the next emergency earthquake early warning in the middle of the previous signal.

  The signal transmitted from the intercom 62 in this way is received by the earthquake early warning receiving unit 40 of the kitchen remote control device 2. Further, the earthquake early warning receiving unit 40 of the bath remote control device 1 receives a signal transmitted from the interphone 62 via the kitchen remote control device 2 and the water heater 27. The earthquake early warning reception unit 40 adds the received signal to the seismic intensity information determination unit 42 of each remote control device (own remote control device). Also in the following configuration, the control component of each remote control device applies a signal to the corresponding control component of its own remote control device.

  The earthquake information determination unit 42 determines the seismic intensity information of the emergency earthquake warning according to the form of the signal received by the emergency earthquake warning reception unit 40, that is, according to the waveform and length of the signal as shown in FIG. The judgment information is added to the earthquake information storage unit 44 and the earthquake early warning notification means 41. 6 (a) to 6 (d) are examples that are added to both the earthquake information storage unit 44 and the earthquake early warning notification means 41, and FIGS. 6 (e) and 6 (f) only show the earthquake information storage unit 44. It is an example added to.

  As described above, in this embodiment, at least one of the waveform and the length of the signal transmitted from the signal transmission control unit 30 of the interphone 62 to the remote control device 1 or 2 is determined according to the seismic intensity information of the emergency earthquake warning. Since the earthquake information determination unit 42 of the remote control device 1 or 2 determines the seismic intensity information of the emergency earthquake warning according to the form of the signal, the emergency earthquake warning can be easily and accurately transmitted. Seismic intensity information can be grasped on the remote control device 1 or 2 side.

  The earthquake information storage unit 44 stores the received information received by the emergency earthquake bulletin receiving unit 40 as a history, and stores a plurality of pieces (for example, four) of information on the earthquake early warnings received by the emergency earthquake bulletin receiving unit 40. It has a function to do. The earthquake information storage unit 44 stores, for example, an earthquake early warning signal as a history when the signal is received for a set time of 25 seconds or longer, and stores the seismic intensity information determined by the seismic intensity information determining unit 42 when the emergency earthquake early warning is stored. In addition, the earthquake information storage unit 44 takes in the information of the clock mechanism 51 to obtain the information on the elapsed time since the reception of the earthquake early warning together with the information on the earthquake early warning received by the earthquake early warning receiving unit 40. It is configured to memorize.

  The earthquake early warning notification means 41 notifies the emergency earthquake early warning information received by the emergency earthquake early warning receiving unit 40 in a setting mode including at least one of display and voice. When the earthquake information determination unit 42 receives the seismic intensity determination information of the emergency earthquake information from the earthquake information determination unit 42, the earthquake information notification unit 41 adds the information to the speaker 34 and the display control unit 45.

  From the speaker 34, the sound of “Earthquake Early Warning” and the sound of “Peep” are alternately and repeatedly transmitted for a set time such as 1 minute after the earthquake early warning notifying means 41 receives the signal. In addition, the sound of seismic intensity information may be transmitted together with the sound of the earthquake early warning, such as “emergency earthquake early warning, seismic intensity 5”. During the transmission of these voices and “Peep” sounds, even if there is a voice guidance for notification such as “Notice 5 minutes ago”, the voice guidance is canceled. In addition, if the “emergency earthquake warning” is transmitted during BGM, the BGM is muted. Then, the outgoing voice of “Earthquake Early Warning” is set to the maximum level among a plurality of set volume levels regardless of the set volume of the voice guidance for notification other than the Earthquake Early Warning. It is also possible to provide a function capable of setting a dedicated transmission volume larger than the maximum level transmission volume, and to transmit the “Earthquake Early Warning” voice with this dedicated transmission volume.

  In addition, it may be transmitted with the same sound quality as that of the voice guidance for notification, or may be transmitted with a different dedicated transmission sound quality. May be transmitted at a large level. These temperature and volume settings may be made in advance when the hot water heater 27 is shipped, or the remote control devices 1 and 2 may be provided with setting means for these settings. When the earthquake early warning is a false alarm, the transmission of the “emergency earthquake early warning” sound and the sound of “peep” are canceled.

  The display control unit 45 displays the fact that the earthquake early warning reception unit 40 has received the earthquake early warning and the seismic intensity information (the seismic intensity information determined by the seismic intensity information determining unit 42) by controlling the display screen 32. To distinguish between them. Specifically, the display control unit 45 displays characters such as “Seismic intensity 3” and “Seismic intensity 4” on the display screen 32 together with the characters “Earthquake Early Warning”, or displays only the numbers representing the seismic intensity. To do. Further, the display control unit 45 repeatedly performs blinking display of the lamp 39 and lamp blinking display of various operation switches (hidden operation switches) provided in the area A where the lid portion 48 is opened.

  The display of the emergency earthquake bulletin by the display control unit 45 is performed for a predetermined period after the emergency earthquake bulletin is received by the emergency earthquake bulletin receiving unit 40. In the present embodiment, the display control unit 45 takes in the information of the clock mechanism 51 and receives the earthquake early warning when the earthquake early warning receiving unit 41 receives the earthquake early warning while the water heater 27 is operating. During the predetermined period (for example, 1 minute), the received emergency earthquake warning information and the operation related information of the water heater 27 are alternately displayed on the display screen 32. Note that the display is canceled when there is a false alarm. In the present embodiment, as described above, the seismic intensity information accurately determined is displayed on the display screen 32 by the display control unit 45, so that the display can also be accurately performed.

  The display control unit 45 displays the display time of the emergency earthquake warning information when the information on the emergency earthquake warning and the operation related information of the water heater 27 are alternately displayed on the display screen 32. Make it longer than the information display time. For example, the display time of emergency earthquake bulletin information is 0.8 seconds, and the display time of operation related information of the water heater 27 is 0.5 seconds. The display control unit 45 also displays the display brightness of the information on the emergency earthquake warning when the information on the emergency earthquake warning and the operation related information of the water heater 27 are alternately displayed on the information display unit. It is made larger than the display brightness of information. As an example, the display of emergency earthquake bulletin will be displayed as “Emergency earthquake bulletin” as shown in FIG. 3, but the method of displaying the emergency earthquake bulletin is not particularly limited and can be set appropriately. It is what is done.

  The display control unit 45 is configured to continuously display the information on the emergency earthquake bulletin on the display screen 32 when the earthquake early warning receiving unit 41 receives the emergency earthquake bulletin while the operation of the water heater 27 is stopped. .

  The notification setting means 31 can be provided in both the bath remote control device 1 and the kitchen remote control device 2, but is provided only in the bath remote control device 1 in this embodiment. The alert setting means 31 is used to notify the earthquake early warning means 41 of both the signal-connected remote control device (that is, the kitchen remote control device 2 here) and its own remote control device (that is, the bath remote control device 1 here). Set whether or not to display one or both.

  For example, the lid 48 of the bath remote control device 1 is opened, and the operation switch formed in the area A in FIG. 4 is operated to display “Menu”, “Other”, “D-5” on the display screen 32. Are displayed on the display screen 32 in this order. Then, as shown in FIG. 7, in the “Kitchen Earthquake Early Warning Voice” screen display, by selecting “ON” and confirming, the kitchen remote control device 2 decides to make an emergency earthquake warning voice notification. To do. As described above, providing the notification setting unit 31 is convenient because the notification setting unit 31 can set the presence / absence of voice notification and display as necessary.

  In the present embodiment, the operation instruction operation means 37 is various means for performing operations other than the operation switch 35. The operation instruction operation switch such as the rework switch 33 and the automatic switch 36, the call switch 38, and various settings. A plurality of means such as operation switches for operation instructions are shown.

  The instruction operation acceptance control means 43 does not accept an instruction according to the operation, even if the operation instruction operation means 37 is operated, during the operation in the earthquake early warning notification mode in which the earthquake early warning notification means 41 performs notification. Only instructions accompanying the operation of the switch 35 are accepted.

  That is, in this embodiment, the power supply circuit (not shown) and the combustion operation control circuit (not shown) of the hot water heater 27 are both operated by the operation switch 35 and the operation instruction operation via the instruction operation reception control means 43. When the emergency earthquake bulletin is received by the emergency earthquake bulletin receiving unit 40, only the operation of the water heater 27 according to the operation of the operation switch 35 is performed according to the control by the instruction operation reception control unit 43. By doing so, the operation of turning off the water heater 27 is enabled, and other operations (operations such as automatic operation and chasing) are not performed. The operation of the hot water heater 27 can be turned on in accordance with the operation of the operation switch 35 by the control of the instruction operation reception control means 43. However, when the emergency earthquake warning is transmitted, It is not necessary to turn 27 driving from off to on.

  In addition, in accordance with this control, the instruction operation reception control means 43 is in addition to the display control unit 45 in addition to the display control unit 45 so that the lamp 39 provided in the operation switch 35 is lit when operating in the earthquake early warning notification mode. Turns on the lamp 39 of the operation switch 35.

  Further, in this embodiment, when the earthquake early warning notifying unit 41 operates in the earthquake early warning notification mode, as described above, an instruction such as a chasing driving instruction according to the operation of the operation instruction operating unit 37 is not accepted. When the operation unit 37 is operated for a predetermined number of times of voice cancel setting, the voice notification by the earthquake early warning notification unit 41 is canceled, and further, the predetermined number of times of voice re-notification set during operation of the earthquake early warning notification mode. Only when the operation instruction operation means 37 is operated, the sound notification by the earthquake early warning notification means 41 is resumed.

  Note that one value can be set for each of the voice cancel setting number and the voice re-notification setting number, but in this embodiment, the voice cancel setting number is an odd number and the voice re-notification setting number is an even number. That is, the sound notification by the earthquake early warning notification means 41 is canceled when one of a plurality of switches constituting the operation instruction operation means 37 is pressed once, and resumed when pressed twice. Every time 37 is pressed, the presence / absence of voice notification by the earthquake early warning notification means 41 is switched alternately.

  By configuring the remote control devices 1 and 2 in this way, users who do not want to be notified of the receipt of the earthquake early warning repeatedly by voice after knowing the receipt of the earthquake early warning The voice notification can be canceled by pressing the instruction operation unit 37 an odd number of times, and the voice notification can be resumed by pressing the operation instruction operation unit 37 an even number of times. Therefore, for example, if the user wants to cancel the voice notification after the voice notification of the earthquake early warning, for example, it can be easily performed. Even if the voice notification of the emergency earthquake warning is canceled, the voice notification can be resumed when the user wants to resume the operation and the usability can be improved.

  Further, when the operation instruction operation means 37 is continuously operated for a predetermined voice cancellation time (for example, 3 seconds) or longer (when the notification cancellation operation is performed) during the operation in the seismic warning notification mode. Until the next earthquake early warning receiving unit 40 receives the earthquake early warning, the voice notification by the earthquake early warning notifying means 41 of the remote control devices 1 and 2 and the “emergency earthquake early warning” on the display screen 32 of the bath remote control device 1 are performed. The display is canceled. In this way, after knowing that the earthquake early warning has been received by the notification of the earthquake early warning means 41, it is possible to improve the usability for the user who does not want to repeatedly notify the emergency earthquake early warning.

  If a short circuit failure occurs at the connecting portion between the kitchen remote control device 2 and the interphone 62, the kitchen remote control device 2 side, although there is no emergency earthquake warning signal transmitted from the interphone 62 to the kitchen remote control device 2. Then, the state where the earthquake early warning was received will continue. In that case, since the code display as shown in FIG. 5 is continuously performed for a long time on the display screen 32 of the kitchen remote control device 2, it is known that a failure such as the short failure has occurred. Can do. On the other hand, if the display of the emergency earthquake warning code on the display screen 32 of the kitchen remote control device 2 is canceled when the notification canceling operation is performed, even if a failure such as the short failure occurs. I don't know. For this reason, in this embodiment, even if the cancel operation is performed, the code display of the earthquake early warning reception in the kitchen remote control device 2 is not canceled.

  The display operation unit 46 performs an operation for displaying the information stored in the earthquake information storage unit 44 on the display screen 32. The display operation unit 46 includes an operation switch provided in the area A where the lid 48 of the remote control device 1 is opened, and is operated based on the display on the display screen 32. And according to operation of the display operation part 46, as a structure which displays the information of the corresponding emergency earthquake early warning on the display screen 32 selectively among the information of the several earthquake early warnings memorize | stored in the earthquake information storage part 44 Yes.

  For example, by operating an operation switch such as a menu switch, the display screen 32 displays “menu”, “others”, and “D-4” in this order. When there is no history, as shown in FIG. 8A, the display screen 32 displays “No earthquake early warning history and no reception history”. Also, if there is an emergency earthquake warning history, as shown in FIG. 8B, the display screen 32 displays “Earth earthquake early warning history and reception history are two.” Is displayed. That is, in the present embodiment, the number of emergency earthquake bulletins stored in the earthquake information storage unit 44 is displayed on the display screen 32 in accordance with the operation of the display operation unit 46.

  After displaying the number of earthquake early warnings, the first information (latest information) in the reception history is displayed by operating the display operation unit 46 or after the set time for display switching has elapsed (FIG. 8C). In this state, the earthquake information storage unit is appropriately pressed by pressing the “△” and “▽” switches of the setting-related operation unit (operation switch) in the area shown in FIG. The second and subsequent information stored in 44 is displayed. In addition, in the display of each earthquake early warning, the elapsed time is also displayed. The function for displaying the elapsed time in detail is set for a maximum of 30 days, and if it is longer than that, the display is “30 days or more ago”. The display of the reception history is switched to hot water supply related information after a set time of, for example, 30 seconds (hot water supply related information is displayed on the display screen 32).

  The earthquake early warning history deletion operation unit 47 is an operation unit for deleting the emergency earthquake early warning stored in the earthquake information storage unit 44. In this embodiment, the earthquake early warning history erasing operation unit 47 is configured to include an operation switch provided in the area A where the lid 48 of the remote control device 1 is opened, and is operated based on the display on the display screen 32. Is done. That is, the earthquake early warning history erasure operation unit 47 displays an information erasure screen for guiding a procedure for erasing information stored in the earthquake information storage unit 44 on the display screen 32, and the earthquake information storage unit 44 stores the information. It is an operation part for performing operation which deletes the earthquake early warning which is doing.

  For example, “Menu”, “Others”, and “D-4” are displayed on the display screen 32 in this order, and this “D-4” is selected and displayed on the display screen 32 as shown in FIG. With the number of earthquake warnings displayed, if you press the “△” marked up switch continuously for 3 seconds or longer, the display screen 32 will display “Delete?” When the determination switch is pressed in the state, all the earthquake early warning reception histories stored in the earthquake information storage unit 44 are erased. As shown in FIGS. 8 (c) and 8 (d), individual emergency earthquake warning information is set by setting an operation method for deleting individual emergency earthquake warning information one by one or multiple records. There may be provided a configuration for erasing.

  Such a function for deleting the history of the emergency earthquake warning is performed, for example, when the earthquake early warning receiving unit 40 receives the emergency earthquake warning when the water heater 27 is constructed. This is because even if the earthquake early warning is received during construction of the water heater 27, it is not particularly necessary for the user of the water heater 27 to know the history.

  This embodiment is configured as described above. When an emergency earthquake warning is transmitted, the signal transmission control unit 30 of the interphone 62 transmits the information to the remote control device 2 according to the seismic intensity information of the emergency earthquake warning. The remote control device 2 receives the signal (the remote control device 1 transmits the signal to the remote control device 2 and the water heater 27). Because it determines the seismic intensity information of the emergency earthquake warning according to the form of the received signal, and displays the seismic intensity information separately or by voice notification, easily and accurately, The seismic intensity information of the earthquake early warning can be transmitted to the user.

  In addition, this information notification is performed even if an indoor person (home person) does not knowingly operate and deliberately listen to it. Can urge you to prepare for an earthquake.

  Further, according to the present embodiment, since the instruction accompanying the operation of the operation switch 35 is accepted even in the operation of the earthquake early warning notification mode for notifying the transmission of the emergency earthquake early warning, the operation of the water heater 27 can be stopped in preparation for the earthquake, Even if the operation instruction operation means 37 other than the operation switch 35 is operated, an instruction corresponding to the operation is not accepted, so that the operation of the water heater 27 can be turned off before the earthquake arrives. Without accepting other operations or settings, the user can be prompted to deal with the arrival of an earthquake.

  Furthermore, according to the present embodiment, the earthquake early warning is notified by the earthquake early warning means 41, and when the earthquake early warning is transmitted while the user is at home, the emergency earthquake early warning can be accurately notified. However, at this time, during the predetermined period after the earthquake early warning receiving unit 40 receives the emergency earthquake early warning, the information on the received emergency earthquake early warning and the operation related information of the heat source device are alternately displayed on the information display unit. By displaying it, it is possible to inform the user at home that the earthquake early warning has been received, and to inform the user of the operation related information of the heat source device at that time, and to promote appropriate judgment. .

  In this embodiment, when the earthquake early warning receiving unit 40 receives the emergency earthquake early warning while the water heater 27 is operating, the information on the emergency earthquake early warning and the operation related information of the water heater 27 are displayed on the display screen 32. However, when the emergency earthquake bulletin receiving unit 40 receives the emergency earthquake bulletin while the operation of the water heater 27 is stopped, the information on the emergency earthquake bulletin is continuously displayed on the display screen 32. Therefore, when the operation of the water heater 27 is stopped and it is not necessary to inform the user of the operation related information of the water heater 27, the information of the emergency earthquake bulletin is displayed continuously and the information of the emergency earthquake bulletin is displayed to the user. Can be informed accurately.

  Furthermore, according to the present embodiment, the information related to the emergency earthquake warning when the information on the emergency earthquake warning and the operation related information of the heat source device are alternately displayed on the information display unit is the operation related information of the hot water heater 27. The information display of the emergency earthquake warning can be made conspicuous by making the display brightness of the information of the emergency earthquake warning higher than the display brightness of the operation related information of the water heater 27. It is possible to further encourage the user to take action associated with receiving the earthquake early warning.

  In addition, according to the present embodiment, the information of the emergency earthquake warning can be stored as a history by the earthquake information storage unit, so that the user who has been absent can save the history stored in the earthquake information storage unit after returning home. Based on this, it is possible to notify the reception of the earthquake early warning, the information on the elapsed time after receiving the earthquake early warning, and the seismic intensity of the earthquake.

  Furthermore, according to the present embodiment, the earthquake information storage unit 44 has a function of storing a plurality of pieces of information on the earthquake early warnings received by the emergency earthquake bulletin receiving unit 40, and according to the operation of the display operation unit 46, Since the number of incidents and the corresponding earthquake early warning information can be selectively displayed on the display screen 32, the selected information can be notified by display to the user who was away.

  Furthermore, according to the present embodiment, the information display screen includes an earthquake early warning history deletion operation unit 47 and guides a procedure for deleting the information stored in the earthquake information storage unit 44 by the operation. Since the earthquake early warning that is displayed on the screen 32 and stored in the earthquake information storage unit 44 can be erased, the emergency earthquake early warning can be erased as necessary.

  In addition, this invention can take various embodiment, without being limited to the said Example. For example, the signal transmitted from the intercom 62 to the remote control device 2 side is not limited to the form shown in FIG. 6 and is appropriately set. It is good also as a signal which can distinguish a kind of seismic intensity.

  Further, when displaying the earthquake early warning on the display screen 32, a QR code (QR code is a trademark) is displayed on the display screen 32 as shown in FIG. 9 together with the information stored in the earthquake information storage unit 44, for example. You may make it do. The QR code displayed here is used to access an external earthquake information management mechanism that manages the contents of the earthquake early warning received by the earthquake early warning receiving unit 40 through the Internet using an information terminal such as a mobile phone. Communication access code. Further, a communication access code other than the QR code may be displayed on the display screen 32.

  Further, magnitude information may be transmitted, displayed, notified, and stored in place of or in addition to the seismic intensity information notified in the embodiment. Depending on the magnitude of the magnitude and the location of the epicenter, the probability of a tsunami occurring due to an earthquake varies, so if the magnitude information can be detected in advance, it will be easier to deal with the tsunami. Important for local people facing the coast. Tsunamis may arrive after a long time since the occurrence of the earthquake.

  At present, if there is a possibility of a tsunami after an earthquake, a tsunami is generated from a speaker installed on a telegraph pole through disaster prevention radio to local people facing the coast. Although there is a possibility of evacuation because of the possibility of a disaster, if the heat insulation of the dwelling unit is advanced and double glass or the like is applied to the window, the disaster prevention radio is difficult to hear. Even in such a case, in the present invention, by notifying the earthquake earthquake magnitude information together with the earthquake early warning by using an indoor operation device such as a remote control device, it is possible to notify the person who is indoors of the possibility of the occurrence of a tsunami. In addition, by storing the magnitude information, it is possible to notify the person who has returned from the outside to the house indoors about the possibility of the occurrence of the tsunami.

  Further, in the embodiment, when the earthquake early warning receiving unit 40 detects the reception of the earthquake early warning, the voice, the blinking of the lamp 39, and the message display on the display screen 32 are performed. The earthquake early warning may be notified so that the seismic intensity information can be understood from at least the display.

  Furthermore, when displaying the history of the earthquake early warning, in the above embodiment, the elapsed time after receiving the earthquake early warning is displayed, but instead, the date and time of receiving the earthquake early warning is displayed. Alternatively, information on both the date and time of receiving the earthquake early warning and the elapsed time since receiving the earthquake early warning may be stored.

  Furthermore, in the embodiment, when the earthquake early warning receiving unit 40 detects the reception of the earthquake early warning, the voice, the blinking of the lamp 39, and the message display on the display screen 32 are performed. You may alert | report an emergency earthquake bulletin by one or two. The display method on the display screen 32 is also set as appropriate.

  Further, in the embodiment, the earthquake early warning history erasure unit 47 displays the information erasure screen for guiding the procedure for erasing the information stored in the earthquake information storage unit 44 on the display screen 32 to store the earthquake information storage. Although the operation for deleting the earthquake early warning stored in the unit 44 is performed, the earthquake early warning history deleting unit 47 does not display the information deletion screen or the like, and the earthquake information storage is performed by a simple on / off operation. The unit 44 may perform an operation of deleting the emergency earthquake bulletin stored in the unit 44.

  Further, in the remote control device 1, details of the operation switches provided inside the lid portion 48 (provided in the area A in FIG. 4) and how to operate the switches are set as appropriate. Therefore, the remote control devices 1 and 2 can perform various settings and operations. For example, by pressing two operation switches at the same time, a display that is not normally displayed on the display screen 32 (for example, an emergency earthquake warning history deletion screen) may be displayed.

  Furthermore, in the above embodiment, the control configuration related to the earthquake early warning as shown in FIG. 1 is provided, but the remote control device applied to the emergency earthquake bulletin transmission / reception system of the present invention includes the configuration shown in FIG. At least the earthquake early warning reception unit 40, the seismic intensity information determination unit 42, and the seismic intensity information determined by the seismic intensity information determination unit 42 need only be configured to be displayed separately on the display screen 32. Are provided as appropriate.

  For example, in the present embodiment, the display time of the information on the emergency earthquake warning when the information on the emergency earthquake warning and the operation related information of the heat source device are alternately displayed on the information display unit is the operation related information of the water heater 27. Both the display time control for making the display time longer than the display time and the display brightness control for making the display brightness of the emergency earthquake warning information higher than the display brightness of the operation-related information of the water heater 27 may be performed. However, these controls may not be performed. Further, it is not necessary to alternately display the driving related information when displaying the earthquake early warning. For example, attention may be drawn by continuous display of earthquake early warning or flashing display of “earthquake display” and “light off”.

  Furthermore, in the above-described embodiment, an example in which the bath remote controller 1 and the kitchen remote controller 2 are electrically connected via the control device 3 of the water heater 27 has been described. However, for example, an additional remote controller provided in a bathroom or the like May be electrically connected to the bath remote controller 1 or the kitchen remote controller 2 via the controller 3. In this case, similarly to the bath remote controller 1 and the kitchen remote controller 2, the extension remote controller is also provided with the earthquake early warning receiving unit 40, the earthquake information storage unit 44, and the like. You may be able to perform.

  Further, in the above embodiment, when the earthquake early warning receiving unit 40 receives the emergency earthquake early warning while the operation of the water heater 27 is stopped, the emergency earthquake early warning information is displayed continuously. Instead, the user may be alerted with blinking displays of “earthquake display” and “off”.

  Furthermore, the remote control device of the present invention may or may not have, for example, a radio broadcast or text broadcast reception and playback function, or other broadcast reception functions such as TV broadcast, intercom functions, etc. Those with additional functions may be used.

  Furthermore, in the above embodiment, the hot water heater 27 to which the remote control device is connected is a hot water heater using gas as fuel. However, the heat source of the heat source device such as a hot water heater may be gas, oil, electricity, or a hot water storage type. It doesn't matter. Moreover, in the said Example, although the water heater 27 was equipped with the hot water supply function, the hot water filling function, the heat retention function, the reheating function, the addition hot water function, and the lukewarm water function, it does not have all these functions. It may also have other functions.

  Furthermore, the remote control device of the present invention may be an indoor remote control device that is signal-connected to a heat source device such as a bath tub or a heating device other than the water heater 27.

  Furthermore, in the said Example, although the example which provides a remote control device in each house 69 of apartment houses, such as an apartment, the remote control device may be provided in an office etc.

  Furthermore, in each house, the kitchen remote control device 2 may be disposed near the interphone 62. In such a case, if both the interphone 62 and the kitchen remote control device 2 simultaneously notify the earthquake early warning by voice output, On the contrary, the earthquake early warning may not be transmitted to the user. Therefore, for example, depending on the arrangement form of the interphone 62 and the kitchen remote control device 2, the kitchen remote control device 2 does not notify the earthquake early warning by sound output, but the bath remote control device 1 (or the bath remote control device 1 and the additional remote control device). You may make it perform. In this case, the notification setting means 31 of the bath remote control device 1 sets the sound output of earthquake early warning on / off to the kitchen remote control device 2.

  Furthermore, in the said Example, although the alert setting means 31 was provided in the bath remote control apparatus 1, you may provide the alert setting means 31 in the kitchen remote control apparatus 2, or both the bath remote control apparatus 1 and the kitchen remote control apparatus 2 It may be provided. The notification setting means 31 may be a means for setting whether or not the earthquake early warning notification means performs one or both of voice notification and display for at least one of the signal-connected remote control device and its own remote control device. .

  Further, in the embodiment, the signal applied to the intercom 62 is applied to the bath remote control device 1 via the control device 3 of the water heater 27. However, the signal is directly applied to the bath remote controller without passing through the water heater 27. The signal may be added to the remote controller 1 and signal processing may be performed independently by the bath remote controller 1.

  Furthermore, in the above-described embodiment, the emergency earthquake bulletin transmission system as shown in FIG. 2 is applied so that the kitchen remote controller 2 receives a signal applied to the intercom 62 from the receiver 64 side (further, the bath The remote control device 1 is received via the kitchen remote control device 2 and the water heater 27). However, the configuration of the emergency earthquake bulletin transmission system and the method for detecting the reception of the emergency earthquake bulletin are appropriately set. . For example, when an earthquake early warning is delivered to each house at a low cost, at least one of the waveform and length of the signal transmitted to the remote control device is sent to the delivery destination. A signal transmission unit for variably setting according to the transmission may be provided, and the remote control device 1 or 2 as in the above embodiment may be a system that can receive the signal and notify by display or the like.

  Furthermore, in the said Example, although the operating device was set as the remote control apparatus signal-connected to a heat source device, this invention changes the heat source device into the operating device signal-connected to the circuit of household appliances (home appliances). It may be applied to form the earthquake early warning transmission / reception system of the present invention. In addition, in the present invention, the home appliance is a home appliance such as a washing machine, a refrigerator, an air conditioner, a gas stove whose control circuit is driven by a commercial power source, an electrically-operated shutter (shutter), a boiler room or a veranda of an apartment, etc. The boiler etc. which are provided in etc. are also included. In addition, when these are provided not only at home but also in facilities such as a company, a school, and a hotel, they are called home appliances.

  The operation device that is signal-connected to the home appliance is often provided in a home appliance that is signal-connected to the home appliance circuit (commercial power supply drive). A display unit is arranged, and usually an earthquake information storage unit is provided in or near these arrangement regions. In addition, when a household appliances are refrigerators, an information display part exists in the front surface of a door, for example, a display operation part exists in the store | warehouse | chamber of a refrigerator, for example, You may form these two together. In this case, the earthquake information storage unit may be in either. In the case of an air conditioner, for example, the information display unit is on the front surface of the indoor unit, and the display operation unit is on the infrared remote controller, for example. In this case, the earthquake information storage unit is preferably on the indoor unit side.

  In addition, when the operation device is signal-connected to the home appliance device, the power supply electricity (for example, DC12V) to the display operation unit and the information display unit is applied to the signal connection line (for example, two cores), and the home appliance device circuit Signals between the operation units (or display operation units) may be emphasized. Further, a flat-class capacitor (a kind of storage battery, a rechargeable battery for backup) may be used to stabilize the electricity for power supply, which is likely to become unstable due to signal tones on the display operation unit or information display unit side. Not).

  With such a backup power source, even if the commercial power supply actually stops after the occurrence of an earthquake, the backup power source can recall earthquake information storage. For example, if an earthquake is encountered near the seaside, is the epicenter on the inland side? You can obtain clues to determine post-earthquake behavior, for example, via QR codes, such as whether to cooperate in the fire extinguishing in the neighborhood (for example, closing the gas valve of an LPG cylinder) it can.

  The earthquake early warning transmission / reception system of the present invention can be used for disaster prevention because the seismic intensity information of the emergency earthquake early warning can be accurately transmitted to an operation device such as a remote controller and notified by display or the like.
