Description

本発明は、給湯システムに関し、より詳しくは、端末機から通信回線を介して給湯器を遠隔操作できるものに関する。   The present invention relates to a hot water supply system, and more particularly to a remote control of a hot water heater from a terminal via a communication line.

従来、電話回線からの点火指令に応答して風呂用のガス湯沸かし器の自動点火を行うことは例えば特許文献１で知られている。一方、近年では、風呂用のガス湯沸かし器に代えて、バーナを熱源とする熱交換器を有する給湯器が広く普及している。給湯器は、浴槽への自動湯張りだけでなく、例えば、カランやシャワー等の給湯箇所への温水供給にも利用される。給湯器は、一般に、台所や浴室に設置される運転指令部としてのリモコンを有する制御ユニットを備え、リモコンにより、給湯器の運転許可または運転停止の運転切替、自動湯張りするときの湯張り量や湯張り温度、予約運転を行うための時刻等、使用者の要求に応じた指令ができるようになっている（例えば、特許文献２参照）。そして、このような給湯器においても、その利便性を向上させるために、携帯電話、スマートフォン、タブレットやパソコン等の給湯器の使用者が所有する端末機により通信回線を介して給湯器を遠隔操作することが考えられる。   Conventionally, for example, Patent Document 1 discloses that automatic ignition of a gas water heater for a bath is performed in response to an ignition command from a telephone line. On the other hand, in recent years, a water heater having a heat exchanger using a burner as a heat source has been widely used instead of a gas water heater for a bath. The hot water heater is used not only for automatic hot water filling of a bathtub but also for supplying hot water to hot water supply points such as a currant or a shower. A water heater is generally equipped with a control unit having a remote control as an operation command section installed in a kitchen or bathroom. A command according to a user's request such as a hot water filling temperature, a time for performing a reserved operation, and the like can be performed (for example, see Patent Document 2). And even in such a water heater, in order to improve its convenience, the water heater is remotely operated via a communication line by a terminal owned by a user of the water heater such as a mobile phone, a smartphone, a tablet, or a personal computer. It is possible to do.

ここで、上記給湯器は、熱交換器への通水量を検知する通水量検知手段を備え、通水量検知手段で検知される通水量が所定の点火許可水量以上になった場合にバーナを燃焼させる給湯運転を実行するようになっている。また、上記給湯器は、通常、リモコンにより給湯器を「運転許可」状態にした後でしか、通水量が所定の点火許可水量以上になってもバーナの点火操作が行われず、各給湯箇所への温水供給がされない。このため、端末機により給湯器を遠隔操作する場合、端末機からも運転切替ができるようにしておく必要がある。然し、ある使用者が熱交換器を通過した水や温水を使用しているときに、端末機から給湯器が運転切替されると、使用中の温水が突然水に変わったり、水が突然温水に変わったりして、使用者に不快感を与えてしまうという問題がある。   Here, the water heater includes a water flow amount detecting means for detecting a water flow amount to the heat exchanger, and burns the burner when the water flow amount detected by the water flow amount detecting means is equal to or greater than a predetermined ignition permission water amount. A hot water supply operation is performed. In addition, the above-mentioned hot water heater is usually operated only after the hot water heater is in the “permitted” state by a remote controller even if the water flow rate exceeds a predetermined ignition permissible water amount. The hot water is not supplied. For this reason, when the water heater is remotely operated by the terminal, it is necessary to be able to switch operation from the terminal. However, when a user uses water or hot water that has passed through a heat exchanger and the water heater is switched from the terminal, the hot water in use suddenly changes to water, or the water suddenly warms. There is a problem that the user is uncomfortable.

本発明は、以上の点に鑑み、端末機から運転切替できるように給湯器が構成されている場合でも、使用者に不快感を与えることがない給湯システムを提供することをその課題とするものである。   This invention makes it the subject to provide the hot water supply system which does not give a user a discomfort even when the hot water heater is comprised so that operation switching can be performed from a terminal in view of the above point. It is.

上記課題を解決するために、本発明の給湯システムは、バーナを熱源とする熱交換器を有する給湯器と、熱交換器への通水量を検知する通水量検知手段と、給湯器の運転許可または運転停止を指令すると共に、通水量検知手段で検知される通水量が所定の点火許可水量以上になった場合にバーナを燃焼させる給湯運転の実行を指令する運転指令部を有する制御ユニットと、通信回線を介して制御ユニットにアクセスして、給湯器の運転許可または運転停止を遠隔操作できる端末機とを備え、制御ユニットは、通水量検知手段で検知される通水量が点火許可水量以上である間、端末機からの遠隔操作による運転許可または運転停止の指令を無効にするように構成されることを特徴とする。   In order to solve the above-described problems, a hot water supply system of the present invention includes a water heater having a heat exchanger using a burner as a heat source, a water flow amount detecting means for detecting a water flow amount to the heat exchanger, and a water heater operation permission. Or a control unit having an operation command unit for instructing execution of a hot water supply operation for burning the burner when the water flow amount detected by the water flow amount detection means is equal to or greater than a predetermined ignition permission water amount, while commanding the operation stop. A terminal that can access the control unit via a communication line and remotely control the operation permission or stoppage of the water heater, and the control unit detects that the water flow detected by the water flow detection means is greater than or equal to the ignition permitted water flow. For a certain period, it is configured to invalidate an operation permission or operation stop command by remote control from a terminal.

本発明によれば、通水量検知手段で検知される通水量が点火許可水量以上である間、端末機からの遠隔操作による運転許可または運転停止の指令が無効にされるため、熱交換器を通過した水や温水の使用中に、給湯器が運転切替されることがない。その結果、ある使用者が熱交換器を通過した水や温水を使用しているときに、使用中の温水が突然水に変わったり、水が突然温水に変わったりすることがなく、端末機から運転切替をできるように給湯器が構成されている場合でも、使用者に不快感を与えるといった不具合の発生を確実に防止できる。   According to the present invention, the operation permission or operation stop command by remote operation from the terminal is invalidated while the water flow detected by the water flow detection means is equal to or greater than the ignition permitted water volume. The hot water heater is not switched during the use of the passed water or hot water. As a result, when a user is using water or hot water that has passed through a heat exchanger, the hot water in use does not suddenly change to water or water suddenly changes to hot water. Even when the water heater is configured so that the operation can be switched, it is possible to reliably prevent the occurrence of problems such as discomfort to the user.

図１を参照して、本発明の実施形態の給湯システムＨＳは、給湯器１と、給湯器１を制御する制御ユニット２と、通信回線３を介して制御ユニット２にアクセスして、給湯器１を遠隔操作できる端末機４とで構成される。給湯器１は、バーナ１１ａを熱源とする熱交換器１１と、例えば給湯負荷に応じたバーナ１１ａの燃焼量の調整や湯温調節等の給湯器１の作動を統括制御する、マイクロコンピュータで構成されるコントローラ２１とを有する。熱交換器１１には、図外の市水道等の給水源の水を熱交換器１１に導く給水管１２と、熱交換器１１で加熱された温水を浴槽５１や、カランまたはシャワー等の給湯箇所５２に供給するための出湯管１３とが夫々接続されている。給水管１２には、熱交換器１１への通水量を検知する通水量検知手段としての水量センサ１４が設けられている。 Referring to FIG. 1, a hot water supply system HS according to an embodiment of the present invention accesses a control unit 2 via a hot water heater 1, a control unit 2 that controls the hot water heater 1, and a communication line 3. 1 is composed of a terminal 4 that can remotely control 1. The water heater 1 is composed of a heat exchanger 11 that uses the burner 11a as a heat source, and a microcomputer that performs overall control of the operation of the water heater 1 such as adjusting the amount of combustion of the burner 11a according to the hot water supply load and adjusting the temperature of the hot water. And a controller 21. The heat exchanger 11, the water supply of the water, such as an unshown city water and the water supply pipe 12 leading to the heat exchanger 11, the heated hot water in the heat exchanger 11 and the bathtub 5 1, such as Curran or shower It is tapping pipe 13 Togaotto s connection for supplying the hot water portion 5 2. The water supply pipe 12 is provided with a water amount sensor 14 as a water flow amount detecting means for detecting a water flow amount to the heat exchanger 11.

コントローラ２１には、台所や浴室に設置される運転指令部としてのリモコン２２が有線接続され、コントローラ２１とリモコン２２とが本実施形態の制御ユニット２を構成するようになっている。リモコン２２には、運転許可（入）または運転停止（切）の運転切替を行う切替スイッチ２２ａが備えられる。そして、切替スイッチ２２ａを「入」にすると、この指令を受けたコントローラ２１は、給湯器１を「運転許可」状態にし、水量センサ１４で検知される通水量が所定の点火許可水量以上になると、バーナ１１ａの点火操作を行ってバーナ１１ａを燃焼させる給湯運転を実行する。また、リモコン２２では、給湯温度、自動湯張りするときの湯張り量や湯張り温度、予約運転を行うための時刻等、使用者の要求に応じた指令もできるようになっている。なお、給湯器１自体は公知のものが利用されるため、リコモン２２での給湯器１の操作や給湯器１の作動を含め、これ以上の詳細な説明は省略する。   A remote controller 22 as an operation command unit installed in the kitchen or bathroom is wired to the controller 21, and the controller 21 and the remote controller 22 constitute the control unit 2 of the present embodiment. The remote controller 22 is provided with a change-over switch 22a for switching operation between operation permission (ON) and operation stop (OFF). Then, when the changeover switch 22a is set to “ON”, the controller 21 that has received this command puts the water heater 1 in the “operation permitted” state, and the water flow amount detected by the water amount sensor 14 becomes equal to or greater than the predetermined ignition permitted water amount. Then, a hot water supply operation is performed in which the burner 11a is ignited to burn the burner 11a. The remote controller 22 can also provide commands according to the user's request, such as the hot water supply temperature, the amount and temperature of the hot water filling, and the time for performing the reserved operation. In addition, since the well-known thing is utilized for the water heater 1 itself, further detailed description including the operation of the water heater 1 in the re-common 22 and the operation of the water heater 1 is omitted.

端末機４としては、給湯器１の使用者が所有する、携帯電話、スマートフォン、タブレットやパソコン等の携帯端末機や情報端末機が利用され、通信回線３を介してリモコン２２と通信可能となっている。通信回線３としては、Ｗｉ−Ｆｉ、ＰＨＳや携帯電話などの無線回線網、ＬＡＮ、インターネット、ケーブルテレビ網等が利用できる。そして、端末機４により給湯器１を遠隔操作するための制御信号が生成されてリモコン２２に送信され、これに応じてリモコン２２からコントローラ２１に対して指令され、コントローラ２１により給湯器１が使用者の要求通りに作動する。給湯器１は、リモコン２２により給湯器１を「運転許可」状態にした後でしか、水量センサ１４で検知される通水量が所定の点火許可水量以上になってもバーナ１１ａの点火操作が行われない。このため、リモコン２２は、端末機４からの制御信号により、切替スイッチ２２ａの操作による運転許可または運転停止の指令とは別に、コントローラ２１に対して運転許可または運転停止の運転切替の指令を行うようになっている。なお、事業者により運営される図外の管理サーバ機器（ウエブサーバ）を介して端末機４とリモコン２２と通信可能としてもよく、使用者の要求に応じた指令を送信するためのウエブページや、リモコン２２から送信されてくる給湯器１の運転許可または運転停止の状態並びに給湯温度などの給湯器１の運転情報を端末機４に表示できるようにしてもよい。   As the terminal 4, a mobile terminal or an information terminal such as a mobile phone, a smartphone, a tablet or a personal computer owned by the user of the water heater 1 is used, and can communicate with the remote control 22 via the communication line 3. ing. As the communication line 3, a wireless line network such as Wi-Fi, PHS, or a mobile phone, a LAN, the Internet, a cable TV network, or the like can be used. Then, a control signal for remotely operating the water heater 1 is generated by the terminal 4 and transmitted to the remote controller 22, and in response to this, the remote controller 22 instructs the controller 21, and the controller 21 uses the water heater 1. Operates as required by the operator. The water heater 1 performs the ignition operation of the burner 11a only after the water heater 1 is set to the “permitted operation” state by the remote controller 22 and the water flow amount detected by the water amount sensor 14 exceeds the predetermined ignition permission water amount. I will not. For this reason, the remote controller 22 issues a command for permitting operation or switching operation for stopping operation to the controller 21 separately from a command for permitting operation or stopping operation by operating the changeover switch 22a by a control signal from the terminal 4. It is like that. Note that the terminal 4 and the remote controller 22 may be communicable via a management server device (web server) (not shown) operated by a business operator, and a web page for transmitting a command according to a user's request, The operation information of the water heater 1 transmitted from the remote controller 22 such as permission or stoppage of operation of the water heater 1 and the temperature of the water heater 1 may be displayed on the terminal 4.

ここで、上記の如く、端末機４からの遠隔操作により給湯器１の運転切替をできるようにした場合、ある使用者が熱交換器１１を通過した水（切替スイッチ２２ａが「切」の状態）や、温水（切替スイッチ２２ａが「入」の状態）を使用しているときに、端末機４から給湯器１が運転切替されると、使用中の温水が突然水に変わったり、水が突然温水に変わったりするため、使用者に不快感を与えないようにする必要がある。そこで、本実施形態では、水量センサ１４で検知される通水量が点火許可水量以上である間、端末機４からの遠隔操作による運転許可または運転停止の指令を無効にするように構成した。   Here, when the operation of the water heater 1 can be switched by remote operation from the terminal 4 as described above, water that has passed through the heat exchanger 11 by a certain user (the changeover switch 22a is in the “OFF” state). ) Or hot water (when the change-over switch 22a is in the “on” state), when the water heater 1 is switched from the terminal 4, the hot water in use suddenly changes to water, Since it suddenly changes to hot water, it is necessary to avoid discomfort for the user. Therefore, in this embodiment, while the water flow amount detected by the water amount sensor 14 is equal to or greater than the ignition permission water amount, the operation permission or operation stop command by the remote operation from the terminal device 4 is invalidated.

図２を参照して、コントローラ２１は、端末機４から通信回線３を介してリモコン２２にアクセスされてリモコン２２から給湯器１の運転許可または運転停止の指令を受けると（ＳＴＥＰ１１）、水量センサ１４で検知される通水量が点火許可水量以上か否かを判別する（ＳＴＥＰ１２）。そして、通水量が点火許可水量以上である場合には、端末機４からの運転許可または運転停止の指令を無効にし、給湯器１の運転切替を禁止する（ＳＴＥＰ１３）する。一方、コントローラ２１は、通水量が点火許可水量より少ない場合には、端末機４からの運転許可または運転停止の指令を有効にし、給湯器１の運転切替を許可する（ＳＴＥＰ１４）。   Referring to FIG. 2, when the controller 21 is accessed from the terminal 4 via the communication line 3 and receives a command for permitting or stopping the operation of the water heater 1 from the remote controller 22 (STEP 11), the water amount sensor It is determined whether or not the amount of water detected at 14 is greater than or equal to the amount of water permitted for ignition (STEP 12). When the water flow amount is equal to or larger than the ignition permission water amount, the operation permission or operation stop command from the terminal 4 is invalidated and the operation switching of the water heater 1 is prohibited (STEP 13). On the other hand, when the water flow amount is smaller than the ignition permitted water amount, the controller 21 validates the operation permission or operation stop command from the terminal 4 and permits the operation switching of the water heater 1 (STEP 14).

以上によれば、水量センサ１４で検知される通水量が点火許可水量以上である間、端末機４からの遠隔操作による運転許可または運転停止の指令が無効にされるため、熱交換器１１を通過した水や温水の使用中に、給湯器１が運転切替されることがない。その結果、ある使用者が熱交換器１１を通過した水や温水を使用しているときに、使用中の温水が突然水に変わったり、水が突然温水に変わったりすることがなく、端末機４から運転切替をできるように給湯器１が構成されている場合でも、使用者に不快感を与えるといった不具合の発生を確実に防止できる。   According to the above, while the water flow amount detected by the water amount sensor 14 is equal to or greater than the ignition permission water amount, the operation permission or operation stop command by the remote operation from the terminal device 4 is invalidated. The hot water heater 1 is not switched in operation while using the passed water or hot water. As a result, when a user uses water or hot water that has passed through the heat exchanger 11, the hot water that is being used does not suddenly change to water, or the water does not suddenly change to hot water. Even when the water heater 1 is configured so that the operation can be switched from 4, it is possible to reliably prevent the occurrence of problems such as discomfort to the user.

以上、本発明の実施形態について説明したが、本発明の技術思想を逸脱しない範囲で種々の変形が可能である。上記実施形態では、端末機４により給湯器１を遠隔操作するための制御信号が生成されてリモコン２２に送信され、これに応じてリモコン２２からコントローラ２１に対して指令されるものを例に説明したが、これに限定されるものではない。例えば、コントローラ２１に公知の通信機を付設し、端末機４からの制御信号がコントローラ２１に直接送信され、これに応じて、コントローラ２１により給湯器１が作動されるようにしてもよい。また、通水量検知手段として、給水管１２に設けた水量センサ１４を用いるものを例に説明したが、熱交換器１１への通水量を検知できるものであれば、これに限定されるものではない。また、管理サーバ機器を介して端末機４とリモコン２２とを通信可能としているような場合には、給湯器１の運転切替が禁止されるような場合には、これを端末機４に報知するようにしてもよい。   Although the embodiments of the present invention have been described above, various modifications can be made without departing from the technical idea of the present invention. In the above embodiment, an example is described in which a control signal for remotely operating the water heater 1 is generated by the terminal 4 and transmitted to the remote controller 22, and an instruction is given from the remote controller 22 to the controller 21 accordingly. However, the present invention is not limited to this. For example, a known communication device may be attached to the controller 21, and a control signal from the terminal 4 may be directly transmitted to the controller 21, and the water heater 1 may be operated by the controller 21 in response thereto. Moreover, although the thing using the water amount sensor 14 provided in the water supply pipe 12 was demonstrated to the example as a water flow amount detection means, if it can detect the water flow amount to the heat exchanger 11, it will not be limited to this. Absent. Further, when the terminal 4 and the remote controller 22 can communicate with each other via the management server device, when the operation switching of the water heater 1 is prohibited, this is notified to the terminal 4. You may do it.
