Description

本発明は、浴槽内の浴槽水が循環される浴槽水循環回路と、当該浴槽水循環回路を通して浴槽水を循環させる浴槽水循環ポンプと、前記浴槽水循環回路内を流れる浴槽水を加熱する浴槽水加熱部と、前記浴槽水循環回路を通した浴槽水の流動を検出する水流検出部と、保温時間中において、設定追焚時間おきに追焚運転制御を繰り返す保温運転を実行する運転制御部と、が設けられ、
前記運転制御部が、前記追焚運転制御として、前記浴槽水循環ポンプを作動させたときに前記水流検出部にて浴槽水の流動が検出されるときには、浴槽水を目標湯張温度にすべく前記浴槽水加熱部を加熱作動させる加熱処理を実行し、且つ、前記浴槽水循環ポンプを作動させたときに前記水流検出部にて浴槽水の流動が検出されないときには、エラー発報部を作動させるエラー報知処理を実行する入浴システムに関する。
The present invention includes a bathtub water circulation circuit in which bathtub water is circulated, a bathtub water circulation pump that circulates the bathtub water through the bathtub water circulation circuit, and a bathtub water heating section that heats the bathtub water flowing in the bathtub water circulation circuit. , a water flow detection unit that detects the flow of bathtub water through the bathtub water circulation circuit, and an operation control unit that executes a heat retention operation that repeats the reheat operation control at every set reheat time during the heat retention time. ,
As the reheating operation control, when the flow of bath water is detected by the water flow detection section when the bath water circulation pump is operated, the operation control section controls the operation control section to bring the bath water to the target hot water filling temperature. executing a heating process for heating a bathtub water heating section, and when the water flow detection section does not detect the flow of bath water when the bathtub water circulation pump is operated, an error alarm for operating an error alarm section; The present invention relates to a bathing system that performs processing.

かかる入浴システムは、湯張り後に保温運転を実行することにより、浴槽内の浴槽水の温度を入浴者の好みの目標湯張温度(例えば、41℃)に維持させて、良好な入浴を行えるものである。
つまり、一般家庭においては、複数人の家族が順次入浴することになるが、その入浴時刻にはばらつきが生じることになる。このように入浴時刻にばらつきが生じても、保温時間(例えば、4時間)の間は、浴槽水が目標湯張温度(例えば、41℃)に維持されるから、湯張り後に、先に入浴した入浴者のみならず、後から入浴する入浴者においても、目標湯張温度(例えば、41℃)の浴槽水を使用しながら良好に入浴することができる。
Such a bathing system maintains the temperature of the bathtub water in the bathtub at the bathtub temperature desired by the bather (for example, 41° C.) by performing a heat-retention operation after filling the bathwater, allowing the bather to enjoy a good bath. It is.
In other words, in a typical household, multiple family members take a bath one after another, but their bathing times vary. Even if there are variations in the bathing time in this way, the bath water is maintained at the target bath temperature (for example, 41 degrees Celsius) during the warming time (for example, 4 hours), so you can take a bath first after filling the bath. Not only bathers who have already taken a bath, but also bathers who take a bath later can take a good bath while using bath water at the target bath temperature (for example, 41° C.).

そして、運転制御部が、追焚制御として、浴槽水循環ポンプを作動させたときに水流検出部にて浴槽水の流動が検出されるときには、浴槽水を目標湯張温度にすべく浴槽水加熱部を加熱作動させる加熱処理を実行し、且つ、浴槽水循環ポンプを作動させたときに水流検出部にて浴槽水の流動が検出されないときには、エラー発報部を作動させるエラー報知処理を実行する。
従って、浴槽水循環回路を通して浴槽水が循環されていないのにも拘わらず加熱処理が実行されることを回避できることになり、また、エラー報知処理により、浴槽水循環ポンプが故障している等の異常状態の発生を使用者に認識させることができることになる。
When the operation control unit operates the bathtub water circulation pump as reheating control and the water flow detection unit detects the flow of bathtub water, the operation control unit operates the bathtub water heating unit to bring the bathtub water to the target hot water filling temperature. A heating process for heating the bathtub water circulation pump is executed, and when a water flow detection part does not detect the flow of bath water when a bathtub water circulation pump is operated, an error notification process for operating an error notification part is executed.
Therefore, it is possible to avoid heating treatment even though the bathtub water is not being circulated through the bathtub water circulation circuit, and error notification processing can prevent abnormal conditions such as a failure of the bathtub water circulation pump. This makes it possible to make the user aware of the occurrence of the problem.

かかる入浴システムの従来例として、浴室内のリモコンに人体センサと入浴予定者の人数設定スイッチとを設けて、保温時間中に人体センサにより入浴者数を検出し、その入浴者数の累積数が入浴予定者数に達すると、保温運転を停止するようにしたものがある(例えば、特許文献1参照)。 As a conventional example of such a bathing system, a remote controller in the bathroom is equipped with a human body sensor and a switch for setting the number of people scheduled to bathe, and the human body sensor detects the number of bathers during the warming time, and the cumulative number of bathers is calculated. There is a system in which the heat-retaining operation is stopped when the number of people scheduled to take a bath is reached (for example, see Patent Document 1).

特許第2935046号公報Patent No. 2935046

浴槽水循環ポンプを作動させたときに水流検出部にて浴槽水の流動が検出されないことが起きる原因としては、故障により浴槽水循環ポンプが適正通り作動されないことを挙げることができるが、別の原因として、浴槽の排水栓を使用者が開いて、浴槽の浴槽水が排出されることにより、浴槽内に浴槽水が無いことを挙げることができ、このような場合にも、不必要にエラー報知処理が実行される虞がある。 The reason why the water flow detection unit does not detect the flow of bath water when the bath water circulation pump is activated is that the bath water circulation pump is not operating properly due to a malfunction, but there are other causes. , the user opens the drain valve of the bathtub and the water in the bathtub is drained, and there is no water in the bathtub.In such cases, the error notification process is unnecessary. There is a possibility that it will be executed.

つまり、例えば、複数人の家族が順次入浴する場合において、最後に入浴した入浴者が浴槽の排水栓を開いて、浴槽の浴槽水を排出させることがある。このように浴槽の浴槽水を排出させた場合には、運転制御部に対して保温運転の停止指令を指令する必要があるが、保温運転の停止指令を指令することを忘れる虞があり、その結果、不必要にエラー報知処理が実行される虞がある。 That is, for example, when a plurality of family members take a bath one after another, the last bather to take a bath may open the drain valve of the bathtub to drain the water from the bathtub. When the water in the bathtub is drained in this way, it is necessary to issue a command to the operation control unit to stop the heat retention operation, but there is a risk of forgetting to issue the command to stop the heat retention operation. As a result, there is a possibility that the error notification process will be executed unnecessarily.

上記特許文献1においては、入浴者数の累積数が入浴予定者数に達すると、保温運転を停止するものであるから、最後に入浴した入浴者が浴槽の排水栓を開いて、浴槽の浴槽水を排出させても、不必要にエラー報知処理が実行されることを回避できることになる。 In Patent Document 1, when the cumulative number of bathers reaches the number of scheduled bathers, the warming operation is stopped, so the last bather to take a bath opens the drain plug of the bathtub and drains the bathtub. Even if the water is discharged, it is possible to avoid unnecessary error notification processing.

しかしながら、特許文献1においては、入浴者数の累積数が入浴予定者数に達すると、保温時間中であるにも拘わらず、保温運転を停止するものであるため、例えば、急な来客のために、入浴する入浴者が増える等、入浴する予定者数が増えた場合において、保温運転が停止された状態で入浴する入浴者が発生することになる虞があり、使用勝手が悪い不都合がある。
また、例えば、保温時間中において長時間の風呂掃除を行うこと等により、入浴者数が誤検出されると、入浴者数の累積数が入浴予定者数に達していないのも拘わらず、保温運転が停止されるものであるため、保温運転が停止された状態で入浴する入浴者が生じることになる虞があり、この点からも使用勝手が悪い不都合がある。
However, in Patent Document 1, when the cumulative number of bathers reaches the number of scheduled bathers, the heat keeping operation is stopped even though the heat keeping time is in progress. In addition, when the number of people planning to take a bath increases, such as when the number of people taking a bath increases, there is a risk that some people will take a bath with the heat retention operation stopped, which is inconvenient and inconvenient to use. .
In addition, if the number of bathers is incorrectly detected due to, for example, cleaning the bath for a long time during the warming time, the number of bathers may be incorrectly detected even though the cumulative number of bathers has not reached the number of scheduled bathers. Since the operation is stopped, there is a risk that some bathers will take a bath with the heat-retaining operation stopped, which is also inconvenient in terms of usability.

本発明は、上記実状に鑑みて為されたものであって、その目的は、使用勝手を向上させながらも、不必要にエラー報知処理が実行されることを回避できる入浴システムを提供する点にある。 The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a bathing system that can avoid unnecessary execution of error notification processing while improving usability. be.

本発明の入浴システムは、浴槽内の浴槽水が循環される浴槽水循環回路と、当該浴槽水循環回路を通して浴槽水を循環させる浴槽水循環ポンプと、前記浴槽水循環回路内を流れる浴槽水を加熱する浴槽水加熱部と、前記浴槽水循環回路を通した浴槽水の流動を検出する水流検出部と、保温時間中において、設定追焚時間おきに追焚運転制御を繰り返す保温運転を実行する運転制御部と、が設けられ、
前記運転制御部が、前記追焚運転制御として、前記浴槽水循環ポンプを作動させたときに前記水流検出部にて浴槽水の流動が検出されるときには、浴槽水を目標湯張温度にすべく前記浴槽水加熱部を加熱作動させる加熱処理を実行し、且つ、前記浴槽水循環ポンプを作動させたときに前記水流検出部にて浴槽水の流動が検出されないときには、エラー発報部を作動させるエラー報知処理を実行するものであって、その特徴構成は、
浴室内の入浴者を検知する人感センサが設けられ、
前記運転制御部が、前記追焚運転制御において、前記浴槽水循環ポンプを作動させたときに前記水流検出部にて浴槽水の流動が検出されない場合に、前記人感センサの検出情報に基づいて判定した既入浴者数が予め設定した予定者数に達している入浴終了状態であると判定したときには、前記エラー報知処理を実行しない点にある。
The bathing system of the present invention includes a bathtub water circulation circuit through which bathwater in the bathtub is circulated, a bathtub water circulation pump which circulates the bathtub water through the bathtub water circulation circuit, and a bathtub water circulation circuit which heats the bathwater flowing in the bathtub water circulation circuit. a heating unit, a water flow detection unit that detects the flow of bathtub water through the bathtub water circulation circuit, and an operation control unit that executes a heat retention operation that repeats the reheat operation control at every set reheat time during the heat retention time; is established,
As the reheating operation control, when the flow of bath water is detected by the water flow detection section when the bath water circulation pump is operated, the operation control section controls the operation control section to bring the bath water to the target hot water filling temperature. executing a heating process for heating a bathtub water heating section, and when the water flow detection section does not detect the flow of bath water when the bathtub water circulation pump is operated, an error alarm for operating an error alarm section; It executes processing, and its characteristic configuration is as follows:
A motion sensor is installed to detect people bathing in the bathroom.
In the reheating operation control, the operation control unit makes a determination based on the detection information of the human sensor when the water flow detection unit does not detect the flow of bath water when the bath water circulation pump is operated. The error notification process is not executed when it is determined that the number of bathers has reached the preset expected number of bathers.

すなわち、運転制御部が、追焚運転制御において、浴槽水循環ポンプを作動させたときに水流検出部にて浴槽水の流動が検出されない場合には、人感センサの検出情報に基づいて判定した既入浴者数が予め設定した予定者数に達している入浴終了状態であるか否かを判定して、入浴終了状態であると判定した場合には、エラー報知処理を実行しないことになる。 That is, when the operation control section operates the bathtub water circulation pump in reheating operation control and the flow of bathtub water is not detected by the water flow detection section, the flow of the bathtub water determined based on the detection information of the human sensor is detected. It is determined whether or not the bathing is completed in which the number of bathers has reached the preset expected number of bathers, and if it is determined that the bathing is completed, the error notification process will not be executed.

つまり、追焚運転制御において、浴槽水循環ポンプを作動させたときに水流検出部にて浴槽水の流動が検出されないときに、既入浴者数が予め設定した予定者数に達している入浴終了状態である場合には、最後に入浴した入浴者が浴槽の排水栓を開いて、浴槽の浴槽水を排出させている蓋然性が高いとして、エラー報知処理が実行されないため、不必要にエラー報知処理が実行されることを回避できる。 In other words, in the reheating operation control, when the water flow detection unit does not detect the flow of bath water when the bath water circulation pump is activated, the bathing completion state is reached when the number of bathers has reached the preset expected number of bathers. In this case, there is a high probability that the last bather opened the drain valve of the bathtub and drained the water from the bathtub, and the error notification process is not executed, so the error notification process is unnecessary. can be avoided from being executed.

そして、保温時間中においては、既入浴者数が予め設定した予定者数に達しても、保温運転が継続されるものであるから、急な来客等のために、入浴する入浴者数が予定者数よりも増えた場合においても、保温運転により目標湯張温度に維持されている浴槽水を用いて入浴できることになり、使用勝手の向上を図ることができる。 During the heat retention time, even if the number of bathers reaches the preset number of people, the heat retention operation continues, so the number of bathers taking a bath will be reduced to the planned number in case of unexpected guests. Even if the number of bathers exceeds the number of bathers, they can still take a bath using the bathtub water maintained at the target bath temperature by the heat-retaining operation, which improves usability.

また、保温時間中において長時間の風呂掃除を行うこと等により、入浴者数が誤検出されることによって、既入浴者数が予め設定した予定者数に達しても、保温運転が継続されるものであるから、保温運転により目標湯張温度に維持されている浴槽水を用いて入浴できることになり、使用勝手の向上を図ることができる。 In addition, if the number of bathers is incorrectly detected due to cleaning the bath for a long time during the warming time, the warming operation may continue even if the number of bathers reaches the preset expected number. Therefore, it is possible to take a bath using the bathtub water that is maintained at the target bath temperature by the heat-retaining operation, and it is possible to improve usability.

要するに、本発明の入浴システムの特徴構成によれば、使用勝手を向上させながらも、不必要にエラー報知処理が実行されることを回避できる。 In short, according to the characteristic configuration of the bathing system of the present invention, it is possible to avoid unnecessary error notification processing while improving usability.

本発明の入浴システムの更なる特徴構成は、前記運転制御部が、前記追焚運転制御において、前記浴槽水循環ポンプを作動させたときに前記水流検出部にて浴槽水の流動が検出されない場合に、前記入浴終了状態であると判定したときには、前記保温運転を停止する点にある。 A further characteristic configuration of the bathing system of the present invention is that when the operation control section operates the bathtub water circulation pump in the reheating operation control and the flow of bathtub water is not detected by the water flow detection section. , when it is determined that the bathing is completed, the warming operation is stopped.

すなわち、追焚運転制御において、浴槽水循環ポンプを作動させたときに水流検出部にて浴槽水の流動が検出されない場合に、既入浴者数が予め設定した予定者数に達している入浴終了状態であるときには、保温運転が停止されることになるから、不必要に保温運転が継続されることを回避できる。 In other words, in the reheating operation control, if the flow of bathtub water is not detected by the water flow detection unit when the bathtub water circulation pump is activated, the bathing is completed state in which the number of bathers has reached the preset expected number of bathers. In this case, the heat-retaining operation is stopped, so that it is possible to avoid unnecessary continuation of the heat-retaining operation.

つまり、浴槽水循環ポンプを作動させたときに水流検出部にて浴槽水の流動が検出されない場合に、既入浴者数が予め設定した予定者数に達している入浴終了状態であるときには、最後に入浴した入浴者が浴槽の排水栓を開いて、浴槽の浴槽水を排出させている蓋然性が高いものであるから、不必要に保温運転を継続することを回避すべく、保温運転が停止される。 In other words, if the flow of bath water is not detected by the water flow detection unit when the bath water circulation pump is activated, and the number of bathers has reached the preset expected number of bathers, the last Since there is a high probability that the bather opened the drain valve of the bathtub and drained the water from the bathtub, the warming operation is stopped in order to avoid continuing the warming operation unnecessarily. .

要するに、本発明の入浴システムの更なる特徴構成によれば、不必要に保温運転が継続されることを回避できる。 In short, according to the further characteristic configuration of the bathing system of the present invention, it is possible to avoid unnecessary continuation of the heat retention operation.

本発明の入浴システムの更なる特徴構成は、前記運転制御部が、リモコンにて湯張指令が指令されると、前記目標湯張温度の湯水を湯張りする湯張運転を実行し、その後、前記保温運転を実行する点にある。 A further characteristic configuration of the bathing system of the present invention is that, when a hot water filling command is issued by the remote control, the operation control section executes a hot water filling operation for filling hot water at the target hot water filling temperature, and then, The point is to execute the above-mentioned heat retention operation.

すなわち、運転制御部が、リモコンにて湯張指令が指令されると、目標湯張温度での湯張運転を実行し、その後、保温運転を実行するものであるから、リモコンにて湯張指令を指令するだけで、湯張運転、及び、保温運転が順次実行される。 In other words, when the operation control unit receives a hot water filling command from the remote control, it executes hot water filling operation at the target hot water filling temperature, and then performs a warming operation, so the hot water filling command is issued from the remote control. Just by issuing a command, hot water filling operation and warming operation will be executed in sequence.

このように、リモコンにて湯張指令を指令するだけで、湯張運転、及び、保温運転が順次実行されるから、使用勝手の一層の向上を図ることができる。 In this way, the hot water filling operation and the warming operation are sequentially executed by simply issuing the hot water filling command using the remote control, so that usability can be further improved.

要するに、本発明の入浴システムの更なる特徴構成によれば、使用勝手の一層の向上を図ることができる。 In short, according to the further characteristic configuration of the bathing system of the present invention, usability can be further improved.

本発明の入浴システムの更なる特徴構成は、前記リモコンが、前記予定者数を設定できるように構成されている点にある。 A further characteristic configuration of the bathing system of the present invention resides in that the remote controller is configured to be able to set the expected number of people.

すなわち、リモコンにて、入浴する予定者数を設定できるものであるから、入浴システムを設置した際に、リモコンにて入浴する予定者数を設定すれば、入浴システムの設置した当初から、既入浴者数が予め設定した予定者数に達している入浴終了状態を適切に判別できる。 In other words, the number of people scheduled to take a bath can be set using the remote control, so if you set the number of people scheduled to take a bath using the remote control when the bathing system is installed, you To appropriately determine a bathing completion state in which the number of bathers has reached a preset expected number of bathers.

また、入浴する予定者数が変化した場合にも、リモコンにて入浴する予定者数を設定することにより、既入浴者数が予め設定した予定者数に達している入浴終了状態を適切に判別できる。 In addition, even if the number of people scheduled to take a bath changes, by setting the number of people scheduled to take a bath using the remote control, it is possible to appropriately determine when the number of people already taking a bath has reached the preset number of people. can.

要するに、本発明の入浴システムの更なる特徴構成によれば、既入浴者数が予め設定した予定者数に達している入浴終了状態を適切に判別できる。 In short, according to the further characteristic configuration of the bathing system of the present invention, it is possible to appropriately determine the bathing completion state in which the number of bathers has reached the preset expected number of bathers.

本発明の入浴システムの更なる特徴構成は、前記運転制御部が、設定数日間の前記人感センサの検出情報に基づいて、前記予定者数を判定して設定する点にある。 A further feature of the bathing system of the present invention is that the operation control section determines and sets the expected number of people based on the detection information of the human sensor for several days.

すなわち、運転制御部が、設定数日間の人感センサの検出情報に基づいて、予定者数を判定して設定するものであるから、予定者数を人為操作により設定する面倒が無くなるため、使用勝手の一層の向上を図ることができる。 In other words, since the operation control unit determines and sets the planned number of passengers based on the detection information of the human sensor for several days, there is no need to manually set the planned number of passengers. It is possible to further improve convenience.

要するに、本発明の入浴システムの更なる特徴構成によれば、使用勝手の一層の向上を図ることができる。 In short, according to the further characteristic configuration of the bathing system of the present invention, usability can be further improved.

A human sensor M for detecting a human body inside the bathroom Y is provided on the lower surface of the bathroom heater/dryer F. This human sensor M is configured using, for example, a pyroelectric infrared sensor.
The operation control unit C detects a human body inside the bathroom Y based on the detection information of the human sensor M, and then detects the absence of a human body inside the bathroom Y based on the detection information of the human sensor M. When the human body presence detection time up to this point becomes longer than the set determination time (for example, 5 minutes), it is determined that a bather is present inside the bathroom Y.

そして、運転制御部Cが、後述する保温運転を実行する保温時間中において、人感センサMの検出情報に基づいて判別した入浴者の総数である既入浴者数が予め設定した予定者数に達すると、入浴終了状態であると判定するよぅに構成されている。つまり、1回の保温時間中において、人感センサMの検出情報に基づいて判別した既入浴者数が予め設定した予定者数に達すると、入浴終了状態であると判定される。

When performing hot water filling operation and heat retention operation, the operation control unit C executes the determination process described below to determine whether or not bath water is present based on the detection information of the water flow switch 40. , when bathtub water is present, the water level in the bathtub is detected based on the detection information of the water level sensor 39, and in addition, the bathtub water level in the bathtub 1 is detected based on the detection information of the bathtub water temperature detection sensor 38. is configured to detect the temperature of the

すなわち、判定処理においては、循環判定用設定時間の間、排水弁46を閉弁した状態で浴槽水循環ポンプ37を作動させて、その浴槽水循環ポンプ37の作動中において、水流スイッチ40や浴槽水温度検出センサ38の検出情報を読み込んで、浴槽水の存否を確認し、且つ、浴槽水が存在する場合において浴槽水の温度を検出する。
また、水流スイッチ40が水流を検出することを条件として、浴槽水循環ポンプ37を停止させた後、待機用設定時間が経過すると、水位センサ39の検出情報を読み込んで、浴槽内水位を検出するように構成されている。
That is, in the determination process, the bathtub water circulation pump 37 is operated with the drain valve 46 closed during the set time for circulation judgment, and while the bathtub water circulation pump 37 is in operation, the water flow switch 40 and the bathtub water temperature are The detection information of the detection sensor 38 is read to confirm the presence or absence of bathtub water, and if the bathtub water is present, the temperature of the bathtub water is detected.
Further, on the condition that the water flow switch 40 detects water flow, after the bathtub water circulation pump 37 is stopped and a set standby time has elapsed, the detection information of the water level sensor 39 is read and the water level in the bathtub is detected. It is composed of

(湯張運転)
運転制御部Cは、風呂自動スイッチがオン操作されると、判定処理にて判定した浴槽1の湯水の水位が目標水位よりも低いときに、目標湯張温度の湯水を浴槽1に供給する湯張り運転を実行するように構成されている。
湯張運転では、浴槽1に湯を注湯用設定時間に亘り供給する注湯処理と上述の判定処理を交互に実行する処理を、水位センサ39の検出水位が目標水位以上になるまで繰り返し、水位センサ39の検出水位が目標水位以上になると、浴槽水の温度が目標湯張温度になるように追焚する追焚処理を実行した後、湯張り運転を終了する。
(Yubari operation)
When the automatic bath switch is turned on, the operation control unit C controls the operation of supplying hot water at a target bath temperature to the bathtub 1 when the water level of the bathtub 1 determined in the determination process is lower than the target water level. The apparatus is configured to perform tension operation.
In the hot water filling operation, the process of alternately performing the hot water pouring process of supplying hot water into the bathtub 1 over the set time for pouring and the above-described determination process is repeated until the detected water level of the water level sensor 39 becomes equal to or higher than the target water level. When the water level detected by the water level sensor 39 becomes equal to or higher than the target water level, a reheating process is executed to bring the temperature of the bathtub water to the target hot water filling temperature, and then the hot water filling operation is ended.

運転制御部Cは、湯張運転における注湯処理では、湯張電磁弁42を開弁し、且つ、上述の一般給湯運転と同様に給湯バーナ9に点火し、浴槽温度設定スイッチにて設定された目標湯張温度、水量センサ21の検出水量、給水サーミスタ20の検出水温、出湯サーミスタ24の検出温度及び給湯サーミスタ25の検出温度に基づいて、給湯サーミスタ25の検出温度が目標湯張温度になるように、ガス比例弁18の開度及びミキシング弁23の開度を調節し、そして、注湯用設定時間が経過すると、湯張電磁弁42を閉弁し、且つ、給湯バーナ9の燃焼を停止するように構成されている。 In the hot water pouring process during hot water filling operation, the operation control unit C opens the hot water filling solenoid valve 42 and ignites the hot water supply burner 9 in the same manner as in the above-mentioned general hot water supply operation, and sets the temperature using the bathtub temperature setting switch. The temperature detected by the hot water supply thermistor 25 becomes the target hot water supply temperature based on the target hot water supply temperature, the water volume detected by the water flow sensor 21, the water temperature detected by the water supply thermistor 20, the temperature detected by the outlet thermistor 24, and the temperature detected by the hot water supply thermistor 25. The opening degree of the gas proportional valve 18 and the opening degree of the mixing valve 23 are adjusted as shown in FIG. Configured to stop.

また、運転制御部Cは、追焚処理では、端末用熱動弁30を閉弁し且つ追焚用熱動弁34を開弁した状態で熱媒循環ポンプ7及び浴槽水循環ポンプ37を作動させて、浴槽1内の湯水を浴槽水戻り路35及び浴槽水往き路36を通して循環させ、それに併せて、熱媒用加熱部Bにおける熱媒用送風ファン15を駆動した後、断続弁19を開弁してイグナイタにより熱媒加熱バーナ14を点火することになり、さらに、浴槽往温検出センサ47の検出温度が追焚用設定出湯温度(例えば60℃)になるように、ガス比例弁18の開度を調節することになる。 Further, in the reheating process, the operation control unit C operates the heat medium circulation pump 7 and the bathtub water circulation pump 37 with the terminal thermal valve 30 closed and the reheating thermal valve 34 opened. Then, after circulating the hot water in the bathtub 1 through the bathtub water return path 35 and the bathtub water outflow path 36 and driving the heat medium blower fan 15 in the heat medium heating section B, the intermittent valve 19 is opened. In addition, the gas proportional valve 18 is turned on so that the temperature detected by the bathtub temperature detection sensor 47 becomes the set hot water temperature for reheating (for example, 60°C). You will have to adjust the opening.

そして、浴槽水温度検出センサ38の検出温度が目標湯張温度以上になると、断続弁19を閉弁させて熱媒加熱バーナ14の燃焼を停止させ、熱媒用送風ファン15を停止させて追焚処理を終了する。 When the temperature detected by the bathtub water temperature detection sensor 38 becomes equal to or higher than the target hot water filling temperature, the intermittent valve 19 is closed to stop combustion of the heating medium heating burner 14, and the heating medium blower fan 15 is stopped. Finish the burning process.

運転制御部Cは、湯張運転の注湯処理を終了したときに浴槽水温度検出センサ38の検出温度が目標湯張温度以上の場合は、その時点で、報知装置Eを作動させて湯張り運転の終了を報知し、湯張り運転を終了したときに浴槽水温度検出センサ38の検出温度が目標湯張温度よりも低くて追焚処理を実行した場合は、その追焚処理を終了した時点で、報知装置Eを作動させて湯張り運転の終了を報知するように構成されている。 If the temperature detected by the bathtub water temperature detection sensor 38 is equal to or higher than the target hot water filling temperature when the hot water pouring process in the hot water filling operation is finished, the operation control unit C activates the notification device E to start hot water filling at that point. If the temperature detected by the bathtub water temperature detection sensor 38 is lower than the target hot water filling temperature when the completion of the operation is notified and the hot water filling operation is finished, and the reheating process is executed, the time when the reheating process is completed. Then, the notification device E is activated to notify the end of the hot water filling operation.

(保温運転)
運転制御部Cは、上述の如く、湯張運転を終了した後、保温時間(例えば、4時間)が経過するまでの間は、設定追焚時間(例えば、5分~10分)が経過するごとに、浴槽水の温度を目標湯張温度に維持するための追焚運転制御を繰り返す保温運転を実行し、かつ、その保温運転を実行する際に、水位維持制御を実行するように構成されている。
(heat retention operation)
As described above, after the hot water filling operation is completed, the operation control unit C controls the set reheating time (for example, 5 minutes to 10 minutes) to elapse until the heat retention time (for example, 4 hours) has elapsed. The system is configured to execute a heat retention operation that repeats reheating operation control to maintain the temperature of the bathtub water at the target hot water filling temperature, and to execute water level maintenance control when executing the heat retention operation. ing.

すなわち、運転制御部Cは、保温時間中においては、設定追焚時間が経過する毎に、判定処理を実行し、水流スイッチ40の検出情報に基づいて、浴槽水が存在すると判別したときには、浴槽1の湯水の温度及び浴槽1の湯水の水位を検出し、また、判定処理において、水流スイッチ40の検出情報に基づいて、浴槽水が存在しないと判別したときには、報知装置Eを作動させるエラー報知処理を実行するように構成されている。 That is, during the heat retention time, the operation control unit C executes the determination process every time the set reheating time elapses, and when it is determined that there is water in the bathtub based on the detection information of the water flow switch 40, the operation control unit C executes the determination process. 1 and the water level of the bathtub 1, and when it is determined in the determination process that there is no bathtub water based on the detection information of the water flow switch 40, an error notification that activates the notification device E. configured to perform processing.

そして、判定処理を実行した結果、浴槽1の湯水の水位が目標水位よりも低いときは、浴槽1の湯水の温度に拘わらず、注湯処理と判定処理とを順に実行する処理を、水位センサ39の検出水位が目標水位以上になるまで繰り返し、検出水位が目標水位以上になったときに、浴槽水温度検出センサ38の検出温度が目標湯張温度よりも低い場合は、浴槽水温度検出センサ38の検出温度が目標湯張温度以上になるまで、上述の追焚処理を実行することになる。 As a result of executing the determination process, if the water level of the hot water in the bathtub 1 is lower than the target water level, the water level sensor executes the process of sequentially performing the hot water pouring process and the determination process regardless of the temperature of the hot water in the bathtub 1. 39 is repeated until the detected water level becomes equal to or higher than the target water level, and when the detected water level becomes equal to or higher than the target water level, if the detected temperature of the bathtub water temperature detection sensor 38 is lower than the target hot water filling temperature, the bathtub water temperature detection sensor The above-mentioned reheating process is executed until the detected temperature of No. 38 becomes equal to or higher than the target hot water filling temperature.

判定処理を実行した結果、浴槽1の湯水の水位が目標水位以上で且つ浴槽1の湯水の温度が目標湯張温度よりも低いときは、浴槽水温度検出センサ38の検出温度が目標湯張温度以上になるまで、上述の追焚処理を実行することになる。
ちなみに、判定処理を実行した結果、浴槽1の湯水の水位が目標水位以上で且つ浴槽1の湯水の温度が目標湯張温度以上のときは、当然ながら、特別な処理は実行されない。
As a result of executing the determination process, if the water level of the hot water in the bathtub 1 is higher than the target water level and the temperature of the hot water in the bathtub 1 is lower than the target hot water filling temperature, the temperature detected by the bathtub water temperature detection sensor 38 is the target hot water filling temperature. The above-mentioned reheating process will be executed until the above is achieved.
Incidentally, as a result of executing the determination process, if the water level of the hot water in the bathtub 1 is equal to or higher than the target water level and the temperature of the hot water in the bathtub 1 is equal to or higher than the target hot water filling temperature, of course no special process is executed.

つまり、運転制御部Cが、追焚運転制御として、浴槽水循環ポンプ37を作動させたときに水流スイッチ40にて浴槽水の流動が検出されるときには、浴槽水を目標湯張温度にすべく追焚用熱交換器33を加熱作動させる加熱処理として、上述の追焚処理を実行し、且つ、浴槽水循環ポンプ37を作動させたときに水流スイッチ40にて浴槽水の流動が検出されないときには、報知装置Eを作動させるエラー報知処理を実行するように構成されている。 In other words, when the flow of bathtub water is detected by the water flow switch 40 when the bathtub water circulation pump 37 is activated as part of the additional heating operation control, the operation control section C controls the bathtub water to reach the target hot water filling temperature. When the above-mentioned reheating process is executed as the heating process for heating the firing heat exchanger 33 and the bathtub water circulation pump 37 is activated, if the flow of bathtub water is not detected by the water flow switch 40, an alarm is issued. It is configured to execute an error notification process that activates the device E.

また、運転制御部Cが、判定処理において、水流スイッチ40の検出情報に基づいて、浴槽水が存在しないと判別したときに、人感センサMの検出情報に基づいて判定した既入浴者数が予め設定した予定者数に達している入浴終了状態であると判定したときには、エラー報知処理を実行しないように構成されている。
つまり、運転制御部Cが、追焚運転制御において、浴槽水循環ポンプ37を作動させたときに水流スイッチ40にて浴槽水の流動が検出されない場合に、人感センサMの検出情報に基づいて判定した既入浴者数が予め設定した予定者数に達している入浴終了状態であると判定したときには、エラー報知処理を実行しないように構成されている。
In addition, when the operation control unit C determines in the determination process that there is no bath water based on the detection information of the water flow switch 40, the number of bathers determined based on the detection information of the human sensor M is When it is determined that the bathing state has reached the preset number of scheduled bathers, the error notification process is not executed.
That is, in the reheating operation control, when the flow of bathtub water is not detected by the water flow switch 40 when the bathtub water circulation pump 37 is activated, the operation control unit C makes a determination based on the detection information of the human sensor M. When it is determined that the number of bathers who have already taken a bath has reached the preset expected number of bathers, the error notification process is not executed.

また、判定処理において、水流スイッチ40の検出情報に基づいて、浴槽水が存在しないと判別したときに、人感センサMの検出情報に基づいて判定した既入浴者数が予め設定した予定者数に達している入浴終了状態であると判定したときには、保温運転を停止するように構成されている。
つまり、運転制御部Cが、追焚運転制御において、浴槽水循環ポンプ37を作動させたときに水流スイッチ40にて浴槽水の流動が検出されない場合に、入浴終了状態であると判定したときには、保温運転を停止するように構成されている。
In addition, in the determination process, when it is determined that there is no water in the bathtub based on the detection information of the water flow switch 40, the number of bathers determined based on the detection information of the human sensor M is equal to the preset expected number of bathers. When it is determined that the bathing end state has been reached, the warming operation is stopped.
In other words, in the reheating operation control, when the operation control unit C determines that the bathing end state is reached when the flow of bathtub water is not detected by the water flow switch 40 when the bathtub water circulation pump 37 is activated, Configured to stop operation.

If it is determined in #1 that the set reheating time has elapsed, a process is executed to drive the bathtub water circulation pump 37 (#2), and then the water flow switch 40 is in an ON state to detect the flow of bathtub water. It is determined whether or not (#3).
In #3, if it is determined that the water flow switch 40 is in the ON state to detect the flow of bathtub water, the temperature detected by the bathtub water temperature detection sensor 38 is within a range from the target hot water filling temperature to the set allowable temperature (for example, 1°C ) is determined whether the temperature is lower than the temperature obtained by subtracting the temperature (#4), and if it is determined that the temperature is lower than the temperature obtained by subtracting the temperature, a reheating process for heating the bathtub water is executed (#5).

#5の処理に続いて、浴槽水温度検出センサ38の検出温度が目標湯張温度以上であるか否かを判別し(#6)、検出温度が目標湯張温度未満であると判別した場合には、#5の追焚処理を実行する。
#6の処理にて、検出温度が目標湯張温度以上であると判別したときには、浴槽水加熱を停止すべく追焚処理を停止する(#7)。
Following the process in #5, it is determined whether the temperature detected by the bathtub water temperature detection sensor 38 is equal to or higher than the target hot water filling temperature (#6), and if it is determined that the detected temperature is less than the target hot water filling temperature. In this case, the reheating process of #5 is executed.
When it is determined in the process #6 that the detected temperature is equal to or higher than the target hot water filling temperature, the reheating process is stopped to stop heating the bathtub water (#7).

#7の処理に続いて、保温時間が経過したか否かを判別し(#8)、保温時間が経過していない場合には、#1の処理に移行し、保温時間が経過している場合には、保温運転を停止する処理を実行する(#9)。 Following the process #7, it is determined whether or not the heat retention time has elapsed (#8), and if the heat retention time has not elapsed, the process moves to #1 and the heat retention time has elapsed. If so, execute processing to stop the heat retention operation (#9).

#3の処理にて、水流スイッチ40が浴槽水の流動を検出するON状態でないと判別した場合には、人感センサMの検出情報に基づいて判定した既入浴者数が予め設定した予定者数に達している入浴終了状態であるか否かを判別し(#10)、入浴終了状態である判別したときには、保温運転を停止する処理を実行する(#9)。 In the process #3, if it is determined that the water flow switch 40 is not in the ON state for detecting the flow of bathtub water, the number of people who have already taken a bath determined based on the detection information of the human sensor M is equal to the preset number of people who are planning to take a bath. It is determined whether or not the number of baths has reached the bathing end state (#10), and when it is determined that the bathing end state has been reached, a process of stopping the warming operation is executed (#9).

#10の処理にて、入浴終了状態でないと判別したときには、報知装置Eを作動させてエラー報知処理を実行する(#11)。ちなみに、エラー報知処理を実行する際には、保温運転を停止する処理を併せて実行することになる。
尚、エラー報知処理が実行された際には、例えば、リモコンRの運転スイッチを切り操作する等により、エラー報知処理を停止させることになる。
In the process #10, when it is determined that the bathing is not completed, the notification device E is activated to execute the error notification process (#11). Incidentally, when executing the error notification process, a process for stopping the heat retention operation is also executed.
Note that when the error notification process is executed, the error notification process is stopped by, for example, turning off the operation switch of the remote control R.
