You may be comprised so that communication can be performed by radio | wireless. In addition, for example, various types of information may be configured to be communicated between the control device 8 of the heat source device 2 and the control device 13 of the bathroom air-conditioning main body 11 by wire or wireless.

また、温度センサ14は、浴室温度、あるいは、該浴室温度とほぼ同等とみなし得る温度を検出し得るものであれば、浴室空調本体部11以外の箇所に配置されたものであってもよい。例えば、温度センサ14は、浴室リモコン3に搭載されていてもよい。この場合、浴室リモコン3から浴室空調本体部11の制御装置13への情報送信によって、該制御装置13は、浴室温度の検出値を取得することが可能である。   Further, the temperature sensor 14 may be disposed at a place other than the bathroom air-conditioning main body 11 as long as it can detect a bathroom temperature or a temperature that can be regarded as substantially equivalent to the bathroom temperature. For example, the temperature sensor 14 may be mounted on the bathroom remote control 3. In this case, the control device 13 can acquire the detected value of the bathroom temperature by transmitting information from the bathroom remote controller 3 to the control device 13 of the bathroom air-conditioning main body 11.

また、例えば、浴槽BTの湯はり前は、脱衣室UDRの室温は、浴室温度にほぼ一致するとみなし得る。従って、例えば、浴室空調運転用リモコン12に脱衣室UDRの室温を検出する温度センサが搭載されている場合には、浴槽BTの湯はり運転の開始当初(開始時、又はその近辺の時刻)に該温度センサにより検出される温度を、湯はり運転の開始当初の浴室温度として使用することも可能である。   In addition, for example, before the hot water of the bathtub BT, the room temperature of the dressing room UDR can be considered to substantially match the bathroom temperature. Therefore, for example, when the temperature sensor for detecting the room temperature of the dressing room UDR is mounted on the remote controller 12 for the air conditioning operation of the bathroom, at the beginning of the hot water operation of the bathtub BT (at the time of starting or in the vicinity thereof). It is also possible to use the temperature detected by the temperature sensor as the bathroom temperature at the beginning of hot water operation.

また、熱源機2の制御装置8と、浴室空調本体部11の制御装置13とは、ひとまとめに統合して構成することも可能である。   Further, the control device 8 of the heat source device 2 and the control device 13 of the bathroom air-conditioning main body 11 can be integrated and configured.

次に、図2及び図3のフローチャートを参照して、浴槽BTの湯はりを行う場合の作動を説明する。なお、以降の説明では、熱源機2の制御装置8を風呂・給湯用制御装置8、浴室空調本体部11の制御装置13を浴室空調用制御装置13ということがある。   Next, with reference to the flowchart of FIG.2 and FIG.3, the operation | movement in the case of performing the hot water of the bathtub BT is demonstrated. In the following description, the control device 8 of the heat source device 2 may be referred to as a bath / hot water control device 8, and the control device 13 of the bathroom air conditioning main body 11 may be referred to as a bathroom air conditioning control device 13.

ユーザによる前記浴室リモコン3又は台所リモコン4を操作によって、湯はり運転の実行が指示されると、あるいは、ユーザが浴室リモコン3又は台所リモコン4であらかじめ設定したスケジュールに従って、湯はり運転の実行を開始すべき要求が発生すると、風呂・給湯用制御装置8は、図2のフローチャートに示す処理を実行する。   When the user instructs the execution of the hot water operation by operating the bathroom remote control 3 or the kitchen remote control 4, or starts the execution of the hot water operation according to a schedule preset by the user with the bathroom remote control 3 or the kitchen remote control 4. When a request to be generated is generated, the bath / hot-water supply control device 8 executes the processing shown in the flowchart of FIG.

まず、STEP1において、風呂・給湯用制御装置8は、湯はり運転の開始を示す湯はり運転開始情報と、湯はり運転時における風呂給湯装置1及び浴室空調装置10の動作モードとして、暖房・湯はり温度自動調整モードが有効状態(オン)に設定されているか否かを示す運転モード情報とを浴室リモコン3から浴室空調本体部11に送信させる。   First, in STEP 1, the bath / hot water control device 8 uses heating / hot water as the hot water operation start information indicating the start of hot water operation and the operation modes of the bath hot water device 1 and the bathroom air conditioner 10 during hot water operation. The operation mode information indicating whether or not the beam temperature automatic adjustment mode is set to the valid state (ON) is transmitted from the bathroom remote controller 3 to the bathroom air conditioning main body 11.

ここで、暖房・湯はり自動調整モードは、浴槽BTの湯はりの終了後に浴室BRに入室する入浴者のヒートショックが誘発されるのを予防するために、湯はり運転と並行して浴室BRの暖房運転を実行した場合に実現される浴室温度と、浴槽BTに湯はりされる温水の温度との差(絶対値)があまり大きくならないように浴室BRの暖房目標温度(暖房運転による浴室温度の目標値)を自動的に調整する動作モードである。なお、暖房・湯はり自動調整モードでは、浴槽BTに湯はりする温水の温度の調整も適宜行われる。   Here, in the heating / hot water automatic adjustment mode, in order to prevent the heat shock of the bather entering the bathroom BR after the hot water of the bathtub BT is finished, the bathroom BR is performed in parallel with the hot water operation. So that the difference (absolute value) between the bathroom temperature realized when the heating operation is performed and the temperature of the hot water poured into the bathtub BT is not so large (the bathroom temperature by the heating operation) The target mode is automatically adjusted. In the heating / hot water automatic adjustment mode, the temperature of hot water to be poured into the bathtub BT is also adjusted as appropriate.

そして、本実施形態では、ユーザが浴室リモコン3又は台所リモコン4を事前に操作しておくことで、暖房・湯はり温度自動調整モードのオン・オフを、風呂・給湯用制御装置8に対して事前に選択設定することが可能となっている。   In this embodiment, when the user operates the bathroom remote controller 3 or the kitchen remote controller 4 in advance, the heating / hot water temperature automatic adjustment mode is turned on / off to the bath / hot water control device 8. It is possible to select and set in advance.

次いで、STEP2において、風呂・給湯用制御装置8は、暖房・湯はり温度自動調整モードがオンに設定されているか否かを判断する。この判断結果が否定的である場合には、風呂・給湯用制御装置8は、STEP10において、湯はり運転を実行する。このSTEP10の湯はり運転では、風呂・給湯用制御装置8は、ユーザが浴室リモコン3又は台所リモコン4を操作することによって事前に設定した風呂設定温度に一致もしくはほぼ一致させるように加熱した温水を浴槽BTに湯はりする(当該温水を熱源機2から浴槽配管7を介して浴槽BTに供給する)ように、熱源機2の作動制御を行う。   Next, in STEP 2, the bath / hot water control device 8 determines whether or not the heating / hot water temperature automatic adjustment mode is set to ON. When this determination result is negative, the bath / hot water supply control device 8 executes a hot water operation in STEP 10. In the hot water operation of STEP 10, the bath / hot water control device 8 uses hot water heated so as to match or substantially match the bath set temperature set in advance by operating the bathroom remote controller 3 or the kitchen remote controller 4. Operation control of the heat source device 2 is performed so that hot water is poured into the bathtub BT (the hot water is supplied from the heat source device 2 to the bathtub BT via the bathtub piping 7).

また、STEP2の判断結果が肯定的である場合(暖房・湯はり温度自動調整モードがオンに設定されている場合)には、風呂・給湯用制御装置8は、STEP3において、風呂設定温度(浴室リモコン3又は台所リモコン4の操作によりユーザが事前に設定した風呂温度)が、比較的高めの温度である第1閾値温度以上の温度(例えば45℃以上の温度)であるか否かを判断する。   When the determination result in STEP 2 is affirmative (when the heating / hot water temperature automatic adjustment mode is set to ON), the bath / hot water control device 8 determines the bath set temperature (bathroom) in STEP 3. It is determined whether or not the bath temperature set in advance by the user by operating the remote controller 3 or the kitchen remote controller 4 is a temperature higher than a first threshold temperature that is a relatively high temperature (for example, a temperature of 45 ° C. or higher). .

このSTEP3の判断結果が肯定的である場合(風呂設定温度≧第1閾値温度(45℃)である場合)には、風呂・給湯用制御装置8は、STEP4において、湯はり目標温度(浴槽BTに実際に湯はりする温水の目標温度)として、風呂設定温度よりも所定値(例えば3℃)だけ低い温度を設定する。   When the determination result in STEP 3 is affirmative (when the bath set temperature ≧ first threshold temperature (45 ° C.)), the bath / hot water supply control device 8 determines the hot water target temperature (bath BT BT) in STEP 4. As a target temperature of hot water that is actually poured, a temperature that is lower than the bath set temperature by a predetermined value (for example, 3 ° C.) is set.

また、STEP3の判断結果が否定的である場合(風呂設定温度<第1閾値温度(45℃)である場合)には、風呂・給湯用制御装置8は、さらにSTEP5において、風呂設定温度が、前記第1閾値温度(45℃)よりも若干低い第2閾値温度(例えば42℃)よりも高いか否かを判断する。   When the determination result of STEP 3 is negative (when the bath set temperature <the first threshold temperature (45 ° C.)), the bath / hot water supply controller 8 further determines that the bath set temperature is It is determined whether the temperature is higher than a second threshold temperature (for example, 42 ° C.) that is slightly lower than the first threshold temperature (45 ° C.).

そして、このSTEP5の判断結果が肯定的である場合(第2閾値温度(42℃)<風呂設定温度<第1閾値温度(45℃)である場合)には、風呂・給湯用制御装置8は、STEP6において、湯はり目標温度として、第2閾値温度(42℃)を設定する。   When the determination result of STEP 5 is affirmative (when the second threshold temperature (42 ° C.) <Bath set temperature <first threshold temperature (45 ° C.)), the bath / hot water control device 8 In STEP 6, the second threshold temperature (42 ° C.) is set as the hot water target temperature.

また、STEP5の判断結果が否定的である場合(風呂設定温度≦第2閾値温度(42℃)である場合)には、STEP7において、風呂・給湯用制御装置8は、風呂設定温度をそのまま湯はり目標温度として設定する。   When the determination result in STEP 5 is negative (when the bath set temperature ≦ the second threshold temperature (42 ° C.)), in STEP 7, the bath / hot water supply control device 8 uses the bath set temperature as it is. Set as beam target temperature.

以上のSTEP3〜7の処理より、風呂設定温度が第2閾値温度(42℃)よりも高い場合には、湯はり目標温度は、第2閾値温度(42℃)以上の範囲内で、風呂設定温度よりも低い温度(風呂設定温度−3℃の温度又は第2閾値温度(42℃))に決定される。また、風呂設定温度が第2閾値温度(42℃)以下の温度である場合には、湯はり目標温度は、風呂設定温度に一致する温度に決定される。   When the bath setting temperature is higher than the second threshold temperature (42 ° C.), the hot water target temperature is within the range equal to or higher than the second threshold temperature (42 ° C.). It is determined to be a temperature lower than the temperature (bath set temperature-3 ° C. or second threshold temperature (42 ° C.)). When the bath set temperature is equal to or lower than the second threshold temperature (42 ° C.), the hot water target temperature is determined to be a temperature that matches the bath set temperature.

ここで、湯はり目標温度が、上記第2閾値温度(42℃)よりも高いと、後述する浴室BRの暖房運転によって実現される浴室温度(≒後述の暖房目標温度)が浴室BRに隣接する部屋としての脱衣室UDRの温度に比して高くなり過ぎる虞がある。そして、このような場合には、脱衣室UDRから浴室BRに入浴者が入室したときに、該入浴者のヒートショックを誘発する虞がある。そこで、本実施形態では、風呂設定温度が第2閾値温度(42℃)よりも高い場合には、湯はり目標温度を、強制的に、風呂設定温度よりも低い温度に制限する。   Here, when the hot water target temperature is higher than the second threshold temperature (42 ° C.), the bathroom temperature (≈ heating target temperature described later) realized by the heating operation of the bathroom BR described later is adjacent to the bathroom BR. There is a possibility that the temperature becomes too high as compared with the temperature of the dressing room UDR as a room. In such a case, when the bather enters the bathroom BR from the dressing room UDR, there is a risk of inducing a heat shock of the bather. Therefore, in the present embodiment, when the bath set temperature is higher than the second threshold temperature (42 ° C.), the hot water target temperature is forcibly limited to a temperature lower than the bath set temperature.

次に、STEP8において、風呂・給湯用制御装置8は、上記の如く決定した湯はり目標温度を浴室リモコン3から浴室空調本体部11に送信させる。   Next, in STEP 8, the bath / hot water control device 8 transmits the hot water target temperature determined as described above from the bathroom remote controller 3 to the bathroom air conditioning main body 11.

さらに、STEP9において、風呂・給湯用制御装置8は、湯はり運転を実行する。このSTEP9の湯はり運転では、風呂・給湯用制御装置8は、上記の如く決定した湯はり目標温度に一致もしくはほぼ一致させるように加熱した温水を浴槽BTに湯はりするように、熱源機2の作動制御を行う。   Further, in STEP 9, the bath / hot water control device 8 executes hot water operation. In this hot water operation of STEP 9, the bath / hot water control device 8 heats the hot water source 2 so that hot water heated to match or substantially matches the hot water target temperature determined as described above is poured into the bathtub BT. The operation control is performed.

なお、湯はり運転は、浴槽BTの湯はり量(浴槽BTに供給する温水の積算量)が、浴室リモコン3又は台所リモコン4で事前に設定された量に達すると終了される。   The hot water operation is terminated when the hot water amount of the bathtub BT (the accumulated amount of hot water supplied to the bathtub BT) reaches the amount set in advance by the bathroom remote controller 3 or the kitchen remote controller 4.

一方、前記浴室空調用制御装置13は、前記STEP1で浴室リモコン3から送信された前記湯はり運転開始情報及び運転モード情報を受信すると、図3のフローチャートに示す処理を実行する。   On the other hand, when receiving the hot water operation start information and the operation mode information transmitted from the bathroom remote controller 3 in STEP 1, the bathroom air-conditioning control device 13 executes the process shown in the flowchart of FIG. 3.

この場合、まず、STEP21において、前記浴室空調用制御装置13は、浴室BRの暖房運転の実行条件(暖房運転の実行のための必要条件)が成立しているか否かを判断する。本実施形態では、例えば、前記温度センサ14の検出信号により示される浴室温度の検出値(湯はり運転の開始当初の浴室温度の検出値)が、所定温度(例えば15℃)以下である場合に、暖房運転の実行条件が成立する。   In this case, first, in STEP 21, the bathroom air-conditioning control device 13 determines whether or not an execution condition for heating operation of the bathroom BR (necessary condition for executing the heating operation) is satisfied. In the present embodiment, for example, when the detection value of the bathroom temperature (the detection value of the bathroom temperature at the beginning of the hot water operation) indicated by the detection signal of the temperature sensor 14 is equal to or lower than a predetermined temperature (for example, 15 ° C.). The execution condition of the heating operation is established.

なお、上記所定温度は、浴室空調運転用リモコン12の操作によってユーザが可変的に設定し得るものであってもよい。あるいは、上記所定温度は、例えば季節、もしくは気温状態等の環境条件に応じて浴室空調用制御装置13が可変的に設定してもよい。   The predetermined temperature may be variably set by the user by operating the remote control 12 for bathroom air conditioning operation. Alternatively, the predetermined temperature may be variably set by the bathroom air-conditioning control device 13 according to environmental conditions such as season or temperature.

また、例えば、湯はり運転に連動した浴室BRの暖房運転を実行することを許可するか否かを、浴室リモコン3もしくは台所リモコン4、あるいは、浴室空調運転用リモコン12の操作によってユーザが指定し得る場合には、湯はり運転に連動した浴室BRの暖房運転を実行することが許可されている場合に、暖房運転の実行条件が成立するものとしてもよい。   Further, for example, the user designates whether to permit the heating operation of the bathroom BR linked to the hot water operation by operating the bathroom remote controller 3 or the kitchen remote controller 4 or the bathroom air conditioner operation remote controller 12. In the case of obtaining the heating operation, the condition for performing the heating operation may be satisfied when it is permitted to perform the heating operation of the bathroom BR linked to the hot water operation.

STEP21の判断結果が否定的である場合(暖房運転の実行条件が成立しない場合)には、浴室空調用制御装置13の処理は終了する(暖房運転は実行されない)。   When the determination result in STEP 21 is negative (when the heating operation execution condition is not satisfied), the processing of the bathroom air-conditioning control device 13 ends (the heating operation is not executed).

また、STEP21の判断結果が肯定的である場合(暖房運転の実行条件が成立する場合)には、浴室空調用制御装置13は、次に、STEP22において、暖房・湯はり温度自動調整モードがオンに設定されているか否かを、浴室リモコン3から受信した運転情報に基づいて判断する。   If the determination result in STEP 21 is affirmative (when the heating operation execution condition is satisfied), the bathroom air-conditioning control device 13 next turns on the heating / hot water temperature automatic adjustment mode in STEP 22. Is determined based on the driving information received from the bathroom remote controller 3.

このSTEP22の判断結果が否定的である場合には、浴室空調用制御装置13は、STEP28において、暖房運転を実行する。このSTEP28の暖房運転では、浴室空調用制御装置13は、ユーザが浴室空調運転用リモコン12を操作することによって事前に設定した暖房設定温度(暖房運転時の浴室温度の設定値)に、浴室温度の検出値を一致もしくはほぼ一致させるように、浴室空調本体部11の送風ファンの風量(温風の送風量)及び発熱部の発熱量の一方又は両方を制御することで、浴室空調本体部11の作動制御を行う。また、暖房運転の開始前に、24時間換気運転が実行されていた場合には、該換気運転を停止した上で、暖房運転が開始される。   When the determination result in STEP 22 is negative, the bathroom air-conditioning control device 13 executes the heating operation in STEP 28. In the heating operation in STEP 28, the bathroom air-conditioning control device 13 sets the bathroom temperature to the heating preset temperature (the set value of the bathroom temperature during the heating operation) set in advance by the user operating the remote controller 12 for bathroom air-conditioning operation. By controlling one or both of the air volume of the blower fan of the bathroom air-conditioning main body 11 (warm air flow rate) and the heat generation amount of the heat generating part so that the detected values match or substantially coincide with each other, the bathroom air-conditioning main body 11 The operation control is performed. In addition, when the ventilation operation is performed for 24 hours before the heating operation is started, the heating operation is started after the ventilation operation is stopped.

また、STEP22の判断結果が肯定的である場合(暖房・湯はり温度自動調整モードがオンに設定されている場合)には、浴室空調用制御装置13は、STEP23において、浴室リモコン3から送信された湯はり目標温度(前記STEP4又は6又は7で決定された湯はり目標温度)を取得する。   When the determination result in STEP 22 is affirmative (when the heating / hot water temperature automatic adjustment mode is set to ON), the bathroom air-conditioning control device 13 is transmitted from the bathroom remote control 3 in STEP 23. The hot water target temperature (the hot water target temperature determined in STEP 4 or 6 or 7) is acquired.

そして、浴室空調用制御装置13は、取得した湯はり目標温度と、ユーザにより設定された暖房設定温度との温度差(=湯はり目標温度−暖房設定温度)が所定値(例えば15℃)よりも大きいか否かをSTEP24で判断する。   And the control apparatus 13 for bathroom air-conditioning has the temperature difference (= hot water target temperature-heating setting temperature) of the acquired hot water target temperature and the heating preset temperature set by the user from predetermined value (for example, 15 degreeC). It is determined in STEP 24 whether or not is larger.

このSTEP24の判断結果が肯定的となる状況は、暖房設定温度を浴室温度の目標とする暖房運転を湯はり運転と並行して実行したと仮定した場合に、湯はり運転によって浴槽BTに湯はりされた温水の温度(≒湯はり目標温度)が、暖房運転により暖められた浴室温度(≒暖房設定温度)に比して高くなり過ぎるため、浴室BRに入室した入浴者が、浴槽BTに入浴したときに、該入浴者のヒートショックを誘発する虞がある状況である。   The situation in which the determination result in STEP 24 is affirmative is that when it is assumed that the heating operation in which the heating set temperature is the target of the bathroom temperature is performed in parallel with the hot water operation, the hot water operation is performed on the bathtub BT. Since the temperature of the heated water (≒ hot water target temperature) becomes too high compared to the bathroom temperature (≒ heating set temperature) warmed by heating operation, the bather who entered the bathroom BR takes a bath in the bathtub BT When this happens, there is a risk of inducing a heat shock of the bather.

そこで、STEP24の判断結果が肯定的である場合(湯はり目標温度−暖房設定温度>所定値(15℃))である場合には、浴室空調用制御装置13は、STEP25において、暖房運転時の浴室温度の実際の目標温度として使用する暖房目標温度として、湯はり目標温度よりも上記所定値(15℃)だけ低い温度を設定する。   Therefore, if the determination result in STEP 24 is affirmative (the hot water target temperature−the heating set temperature> the predetermined value (15 ° C.)), the bathroom air-conditioning control device 13 determines in STEP 25 that the heating operation is being performed. As the heating target temperature used as the actual target temperature of the bathroom temperature, a temperature lower than the hot water target temperature by the predetermined value (15 ° C.) is set.

また、STEP24の判断結果が否定的である場合(湯はり目標温度−暖房設定温度≦所定値(15℃))である場合には、浴室空調用制御装置13は、STEP26において、暖房設定温度をそのまま暖房目標温度として設定する。   In addition, when the determination result of STEP 24 is negative (hot water target temperature−heating setting temperature ≦ predetermined value (15 ° C.)), the bathroom air-conditioning control device 13 sets the heating setting temperature in STEP 26. Set the heating target temperature as it is.

上記STEP24〜26の処理により、暖房目標温度は、湯はり目標温度との温度差(=湯はり目標温度−暖房目標温度)が上記所定値(15℃)以下に収まるように決定される。   Through the processing of STEPs 24 to 26, the heating target temperature is determined such that the temperature difference from the hot water target temperature (= hot water target temperature−heating target temperature) falls within the predetermined value (15 ° C.).

このように暖房目標温度を決定した後、浴室空調用制御装置13は、STEP27において、暖房運転を実行する。このSTEP27の暖房運転では、浴室空調用制御装置13は、上記の如く決定した暖房目標温度に、浴室温度の検出値を一致もしくはほぼ一致させるように、浴室空調本体部11の送風ファンの風量(温風の送風量)及び発熱部の発熱量の一方又は両方を制御することで、浴室空調本体部11の作動制御を行う。また、暖房運転の開始前に、24時間換気運転が実行されていた場合には、該換気運転を停止した上で、暖房運転が開始される。   After determining the heating target temperature in this way, the bathroom air-conditioning control device 13 executes the heating operation in STEP 27. In the heating operation of STEP 27, the bathroom air-conditioning control device 13 sets the air flow rate of the blower fan of the bathroom air-conditioning main body 11 so that the detected value of the bathroom temperature matches or substantially matches the heating target temperature determined as described above. The operation control of the bathroom air-conditioning main body 11 is performed by controlling one or both of the hot air flow rate) and the heat generation amount of the heat generation unit. In addition, when the ventilation operation is performed for 24 hours before the heating operation is started, the heating operation is started after the ventilation operation is stopped.

本実施形態では、湯はり運転を開始すると、以上の如く、風呂・給湯用制御装置8及び浴室空調用制御装置13の制御処理が協働して実行される。これにより、暖房運転の実行条件が成立する状態で、湯はり運転を開始すると、該湯はり運転と並行して浴室BRの暖房運転が自動的に実行される。   In the present embodiment, when hot water operation is started, the control processing of the bath / hot water control device 8 and the bathroom air conditioning control device 13 is executed in cooperation as described above. Thereby, if the hot water operation is started in a state where the execution condition of the heating operation is satisfied, the heating operation of the bathroom BR is automatically executed in parallel with the hot water operation.

この場合、暖房・湯はり温度自動調整モードがオンに設定されている場合には、暖房運転で実際に使用する浴室温度の目標値としての暖房目標温度が、湯はり目標温度との温度差(=湯はり目標温度−暖房目標温度)を所定値(15℃)以下に収めるように決定される。このため、湯はり運転の終了後に、浴室BRに入室した入浴者が浴槽BTに入浴するときに、浴室温度(≒暖房目標温度)と、浴槽BT内の温水の温度(≒湯はり目標温度)との温度差が過大になるのが防止される。ひいては、入浴者は入浴するときに、該入浴者のヒートショックが誘発されるのを予防することができる。   In this case, when the heating / hot water temperature automatic adjustment mode is set to ON, the heating target temperature as the target value of the bathroom temperature actually used in the heating operation is different from the hot water target temperature ( (= Hot water target temperature−heating target temperature) is determined to be equal to or less than a predetermined value (15 ° C.). For this reason, when a bather entering the bathroom BR takes a bath in the bath BT after the hot water operation is finished, the bath temperature (≈heating target temperature) and the temperature of hot water in the bath BT (≈ hot water target temperature) It is prevented that the temperature difference between and is excessive. As a result, when the bather takes a bath, the bather can prevent the heat shock of the bather from being induced.

また、ユーザにより設定された風呂設定温度が、前記第2温度閾値(42℃)よりも高い場合に、浴槽BTに実際に湯はりする温水の温度の目標値として湯はり目標温度が、強制的に、風呂設定温度よりも低い温度に設定される。ひいては、湯はり運転と並行して実行される暖房運転における暖房目標温度が、脱衣室UDR(浴室BRに隣接する部屋)の温度に対して高くなり過ぎるのが防止される。   Further, when the bath set temperature set by the user is higher than the second temperature threshold (42 ° C.), the hot water target temperature is forcibly set as the target value of the temperature of the hot water actually applied to the bathtub BT. In addition, the temperature is set lower than the bath set temperature. As a result, the heating target temperature in the heating operation performed in parallel with the hot water operation is prevented from becoming too high with respect to the temperature of the dressing room UDR (the room adjacent to the bathroom BR).

このため、湯はり運転の終了後に入浴者が脱衣室UDRから浴室BRに入室するときに、該入浴者のヒートショックが誘発されるのを予防することができる。   For this reason, when the bather enters the bathroom BR from the dressing room UDR after the hot water operation is completed, it is possible to prevent the heat shock of the bather from being induced.

なお、以上説明した実施形態では、図2のフローチャートに示した制御処理を風呂・給湯用制御装置8が実行し、図3のフローチャートに示した制御処理を浴室空調用制御装置13が実行するようにした。ただし、例えば、風呂・給湯用制御装置8及び浴室空調用制御装置13が相互に通信し得る場合には、図2のフローチャートに示した制御処理の一部を、浴室空調用制御装置13で実行し、あるいは、図3のフローチャートに示した制御処理の一部を、風呂・給湯用制御装置8で実行することも可能である。   In the embodiment described above, the control process shown in the flowchart of FIG. 2 is executed by the bath / hot-water supply control device 8 and the control process shown in the flowchart of FIG. 3 is executed by the bathroom air-conditioning control device 13. I made it. However, for example, when the bath / hot water control device 8 and the bathroom air-conditioning control device 13 can communicate with each other, a part of the control processing shown in the flowchart of FIG. Alternatively, a part of the control process shown in the flowchart of FIG. 3 can be executed by the bath / hot water control device 8.

また、前記実施形態では、ユーザによる暖房設定温度と湯はり目標温度との温度差が所定値(15℃)以下である場合には、暖房設定温度をそのまま暖房目標温度として設定した。ただし、例えば、暖房目標温度と湯はり目標温度との温度差が所定値以下に収まる範囲内で、暖房目標温度を、暖房設定温度に依存させずに設定してもよい。   Moreover, in the said embodiment, when the temperature difference of the heating preset temperature by a user and the hot water target temperature is below a predetermined value (15 degreeC), heating preset temperature was set as heating target temperature as it is. However, for example, the heating target temperature may be set without depending on the heating set temperature within a range in which the temperature difference between the heating target temperature and the hot water target temperature falls within a predetermined value.

また、本発明における風呂装置は、給湯機能を持たない装置であってもよい。   Further, the bath apparatus in the present invention may be an apparatus that does not have a hot water supply function.
