Description

本発明は、浴室内に設置された浴槽内に湯を供給する湯張り運転を実行可能な給湯装置と、浴槽の内壁面に向けて湯水又は洗浄液を散布して浴槽を洗浄する浴槽洗浄運転を実行可能な浴槽洗浄装置と、浴室内の雰囲気を調整する空調運転を実行可能な空調装置と、給湯装置、浴槽洗浄装置及び空調装置を制御するコントローラとを備えた浴室システムに関する。 The present invention provides a hot water supply device capable of performing a hot water filling operation that supplies hot water into a bathtub installed in a bathroom, and a bathtub cleaning operation that sprays hot water or cleaning liquid toward the inner wall surface of the bathtub to clean the bathtub. The present invention relates to a bathroom system that includes an executable bathtub cleaning device, an air conditioner that can execute an air conditioning operation to adjust the atmosphere in the bathroom, and a controller that controls a hot water supply device, a bathtub cleaning device, and an air conditioner.

従来、この種の浴室システムとして、浴室内の湿度を検知してコントローラに出力する湿度センサが設けられ、コントローラは、湿度センサの検知出力に基づいて空調装置を制御するものが一般に知られている。 Conventionally, this type of bathroom system is generally known to be equipped with a humidity sensor that detects the humidity in the bathroom and outputs it to a controller, and the controller controls an air conditioner based on the detected output of the humidity sensor. .

ところで、浴槽の上端面を開閉する浴槽蓋が無い状態でコントローラが浴槽洗浄運転の開始指示を受けると、浴槽の内壁面に向けて散布される洗浄液が浴槽の内壁面以外に飛散して、ミスト状の洗浄液が、浴室内に充満したり、浴室の内壁面や天井面に付着したりする。このため、浴室内を入浴等に適した状態に戻すのに非常に手間がかかる。 By the way, if the controller receives an instruction to start the bathtub cleaning operation when there is no bathtub lid to open and close the top end of the bathtub, the cleaning liquid sprayed toward the inner wall of the bathtub will scatter to areas other than the inner wall of the bathtub, causing mist. Cleaning liquid fills the bathroom or adheres to the interior walls and ceiling of the bathroom. Therefore, it takes a lot of effort to return the inside of the bathroom to a state suitable for bathing, etc.

そこで、浴室内に設置される浴室リモコン等に浴室温度を検知する感熱センサを設置し、感熱センサの検知出力に基づいてコントローラが、浴槽蓋の有無判定を行い、その判定結果によって浴槽洗浄装置を制御する浴室システムが提案されている（例えば、特許文献１参照）。 Therefore, a heat-sensitive sensor that detects the bathroom temperature is installed in a bathroom remote control installed in the bathroom, and the controller determines whether or not there is a bathtub lid based on the detection output of the heat-sensitive sensor, and the bathtub cleaning device is activated based on the determination result. A controlled bathroom system has been proposed (for example, see Patent Document 1).

この浴室システムでは、コントローラが浴槽洗浄運転の開始指示を受けた時、給湯装置から湯が浴槽内に供給される。そして、感熱センサの検知出力が、浴槽蓋が無いことに起因して浴槽から立ち上る湯気の熱によって上昇した場合、コントローラは、浴槽蓋無しと判定して浴槽洗浄運転を開始させず、感熱センサの検知出力に変化が現れない場合、コントローラは、浴槽蓋有りと判定して浴槽洗浄運転を開始させる。 In this bathroom system, when the controller receives an instruction to start a bathtub cleaning operation, hot water is supplied from the water heater into the bathtub. If the detection output of the heat-sensitive sensor increases due to the heat of steam rising from the bathtub due to the lack of a bathtub lid, the controller determines that there is no bathtub lid and does not start the bathtub cleaning operation. If no change appears in the detection output, the controller determines that the bathtub lid is present and starts the bathtub cleaning operation.

特開平４－１７４６１５号公報Japanese Patent Application Publication No. 4-174615

然し、特許文献１記載の浴室システムでは、コントローラによる浴槽蓋の有無判定のために感熱センサを別途設置する必要がある。また、感熱センサの感度は、浴槽から立ち上る湯気からの距離や湯気に対する角度によって影響を受けやすく、感熱センサの設置場所には制約がある。 However, in the bathroom system described in Patent Document 1, it is necessary to separately install a heat-sensitive sensor for the controller to determine the presence or absence of a bathtub lid. Furthermore, the sensitivity of the thermal sensor is easily affected by the distance from the steam rising from the bathtub and the angle with respect to the steam, and there are restrictions on where the thermal sensor can be installed.

本発明は、以上の点に鑑み、感熱センサを別途設置することなく既存のシステムを利用して、浴槽蓋の有無判定を行うことができ、その判定結果によって浴槽洗浄装置を制御する浴室システムを提供することをその課題としている。 In view of the above points, the present invention provides a bathroom system that can determine the presence or absence of a bathtub lid by using an existing system without separately installing a heat-sensitive sensor, and that controls a bathtub cleaning device based on the determination result. The task is to provide.

上記課題を解決するために、本発明は、浴室内に設置された浴槽内に湯を供給する湯張り運転を実行可能な給湯装置と、浴槽の内壁面に向けて湯水又は洗浄液を散布して浴槽を洗浄する浴槽洗浄運転を実行可能な浴槽洗浄装置と、浴室内の雰囲気を調整する空調運転を実行可能な空調装置と、給湯装置、浴槽洗浄装置及び空調装置を制御するコントローラとを備えた浴室システムであって、空調装置は、浴室内の空気を吸い込む吸込み口を備え、この吸込み口の近傍に浴室内の湿度を検知してコントローラに出力する湿度センサが設けられ、コントローラは、湿度センサの検知出力に基づいて空調装置を制御するものにおいて、コントローラは、浴槽洗浄運転の開始指示を受けた時、吸込み口から浴室内の空気を吸い込むように空調装置を空調運転させ、更に、給湯装置と浴槽洗浄装置との少なくとも一方から湯を浴槽内に供給させる給湯制御を行うと共に、この給湯制御を行うことによる湿度センサの検知出力の上昇量が、予め設定された閾値未満である場合、浴槽蓋有りと判定して浴槽洗浄運転を開始させる一方、閾値以上の場合、浴槽蓋無しと判定して浴槽洗浄運転を中止させる、浴槽蓋の有無判定に基づく浴槽洗浄運転可否制御を行うことを特徴とする。 In order to solve the above problems, the present invention provides a water heater capable of performing a hot water filling operation that supplies hot water into a bathtub installed in a bathroom, and a water heater that sprays hot water or cleaning liquid toward the inner wall surface of the bathtub. A bathtub cleaning device that can perform a bathtub cleaning operation to clean a bathtub, an air conditioner that can perform an air conditioning operation to adjust the atmosphere in the bathroom, and a controller that controls a hot water supply device, a bathtub cleaning device, and an air conditioner. In the bathroom system , the air conditioner is equipped with an inlet that sucks air in the bathroom, and a humidity sensor that detects the humidity in the bathroom and outputs it to a controller is provided near the inlet. In a device that controls an air conditioner based on the detection output of Hot water supply control is performed to supply hot water into the bathtub from at least one of the and the bathtub cleaning device, and if the amount of increase in the detection output of the humidity sensor due to this hot water supply control is less than a preset threshold, the bathtub It is characterized by performing bathtub cleaning operation enable/disable control based on the determination of the presence or absence of a bathtub lid, in which it is determined that there is a lid and the bathtub cleaning operation is started, while if the threshold value is exceeded, it is determined that there is no bathtub lid and the bathtub cleaning operation is stopped. shall be.

本発明によれば、浴室システムに既設の湿度センサの検知出力の上昇量に基づいて浴槽蓋の有無判定を行うことができ、その判定結果によって浴槽洗浄運転を開始又は中止させることができる。従って、感熱センサを別途設置することなく既存のシステムを利用して、浴槽蓋の有無判定と浴槽洗浄装置の制御とを行うことができる。 According to the present invention, it is possible to determine the presence or absence of a bathtub lid based on the amount of increase in the detection output of a humidity sensor installed in the bathroom system, and it is possible to start or stop the bathtub cleaning operation based on the determination result. Therefore, the existing system can be used to determine the presence or absence of a bathtub lid and to control the bathtub cleaning device without separately installing a heat-sensitive sensor.

更に、本発明によれば、浴槽洗浄運転の開始指示を受けた時、上記の如く吸込み口から浴室内の空気を吸い込むように空調装置を空調運転させるため、吸込み口の近傍に設けられた湿度センサによる湿度検知が迅速且つ正確になる。 Further, according to the present invention, when an instruction to start the bathtub cleaning operation is received, the air conditioner is operated to suck in air from the bathroom through the suction port as described above , so that the humidity control device provided near the suction port is used. Humidity detection by the sensor becomes faster and more accurate.

また、本発明において、前記空調装置が、前記吸込み口を介して浴室内に連通する、空調装置の内部に設けられた通気路と、この通気路と屋外とを連通させる換気路とを備え、通気路内又は換気路内に換気ファンが設けられ、この換気ファンを作動させて浴室内の空気を屋外に排気する換気運転を前記空調運転の一つとして実行可能である場合、前記コントローラは、浴槽洗浄運転の開始指示を受けた時、空調装置を換気運転させた後、前記給湯制御と前記浴槽洗浄運転可否制御とを行うことが望ましい。これによれば、浴室内を換気した後の浴室内の湿度は低下するため、入浴直後に浴槽洗浄運転の開始指示を受けても、湿度センサの検知出力の上昇量が明確になり、コントローラによる浴槽蓋の有無判定が正確になる。 Further, in the present invention, the air conditioner includes a ventilation path provided inside the air conditioner that communicates with the bathroom via the suction port, and a ventilation path that communicates the ventilation path with the outdoors, If a ventilation fan is provided in the ventilation path or in the ventilation path, and a ventilation operation in which the ventilation fan is operated to exhaust air from the bathroom to the outdoors can be performed as one of the air conditioning operations, the controller: When receiving the instruction to start the bathtub cleaning operation, it is preferable to perform the hot water supply control and the bathtub cleaning operation availability control after the air conditioner is operated for ventilation. According to this, the humidity in the bathroom decreases after the bathroom is ventilated, so even if an instruction to start bathtub cleaning operation is received immediately after taking a bath, the amount of increase in the detection output of the humidity sensor becomes clear, and the controller The presence or absence of a bathtub lid can be determined accurately.

更に、本発明において、前記空調装置が、前記通気路から浴室内に空気を吹き出す吹出し口を備え、前記吸込み口と吹出し口との間で前記換気路が通気路から分岐し、通気路内に循環ファン及び熱源が設けられ、空調装置は、循環ファン及び熱源と共に前記換気ファンを作動させて、吸込み口から浴室内の空気を通気路内に吸い込み、吸い込んだ浴室内の空気の一部を熱源で加熱して吹出し口から浴室内に温風として吹き出す一方、吸い込んだ浴室内の空気の残りを換気路を通じて屋外に排気し、浴室内を乾燥させる乾燥運転を前記換気運転の一つとして実行可能である場合、前記コントローラは、浴槽洗浄運転の開始指示を受けた時、空調装置を乾燥運転させた後、前記給湯制御と前記浴槽洗浄運転可否制御とを行うことが望ましい。これによれば、浴室内を乾燥した後の浴室内の湿度はより低下するため、湿度センサの検知出力の上昇量がより明確になり、コントローラによる浴槽蓋の有無判定がより正確になる。 Furthermore, in the present invention, the air conditioner includes an outlet that blows air from the air passage into the bathroom, and the ventilation passage branches from the air passage between the suction port and the air outlet, and the ventilation passage branches into the air passage. A circulation fan and a heat source are provided, and the air conditioner operates the ventilation fan together with the circulation fan and the heat source to draw air from the bathroom into the air passage through the suction port, and use a part of the drawn air in the bathroom as the heat source. As one of the ventilation operations, it is possible to carry out a drying operation in which the bathroom is heated and blown out as warm air from the outlet into the bathroom, while the remaining air in the bathroom is exhausted outside through the ventilation path to dry the bathroom. In this case, when receiving the instruction to start the bathtub cleaning operation, it is preferable that the controller performs the hot water supply control and the bathtub cleaning operation availability control after causing the air conditioner to perform the drying operation. According to this, since the humidity in the bathroom after drying the bathroom is further reduced, the amount of increase in the detection output of the humidity sensor becomes more clear, and the controller can more accurately determine the presence or absence of the bathtub lid.

A plurality of operation switches R22 and R32 are provided, and operation switches R22a and R32a are provided as one of the operation switches R22 and R32 to instruct the bathtub cleaning device 2 to perform bathtub cleaning operation. Further, the bathroom remote control R2 has a built-in controller 4. A kitchen remote controller R3 is connected to the controller 4, and the bathroom remote controller R2 and the kitchen remote controller R3 are interlocked. That is, when an operation switch (for example, operation switch R22a, R32a, etc.) that instructs the same operation among the operation switches R22 and R32 is operated on one of the bathroom remote control R2 and the kitchen remote control R3, the bathroom remote control R2 and The kitchen remote controller R3 is operated at the same time.

The hot water supply heating controller 11 and the bathtub cleaning controller 22 are connected by wire, and the air conditioning controller 36 is connected by wireless.

コントローラ４と浴槽洗浄コントローラ２２との無線接続は、浴室リモコンＲ２及び空調装置３に夫々設けられた赤外線受発光部Ｒ２３，３９によって実現される。赤外線受発光部Ｒ２３，３９は、浴室リモコンＲ２及び空調装置３の夫々で、一方から他方に照射する赤外線を受光することができる位置に配置され、赤外線受発光部Ｒ２３はコントローラ４に接続され、赤外線受発光部３９は空調コントローラ３６に接続されている。 The wireless connection between the controller 4 and the bathtub cleaning controller 22 is realized by the bathroom remote controller R2 and the infrared light receiving/emitting units R23 and 39 provided in the air conditioner 3, respectively. The infrared light receiving and emitting sections R23 and 39 are arranged in the bathroom remote control R2 and the air conditioner 3 at positions where they can receive the infrared rays emitted from one to the other, and the infrared receiving and emitting section R23 is connected to the controller 4, The infrared receiving/emitting section 39 is connected to the air conditioning controller 36.

コントローラ４、給湯暖房コントローラ１１、浴槽洗浄コントローラ２２及び空調コントローラ３６は、いずれも、ＣＰＵ，ＲＯＭ，ＲＡＭ，Ａ／Ｄコンバータ、インターフェース等を備えるマイクロコンピュータから構成されている。コントローラ４は、浴室リモコンＲ２及び台所リモコンＲ３で操作された操作スイッチＲ２２，Ｒ３２の指示信号を給湯暖房コントローラ１１と浴槽洗浄コントローラ２２との少なくとも一方に出力する。図２に示す温度センサ９及び湿度センサ１０が検知した浴室ＢＲ内の温度及び湿度に関する検知信号は、空調コントローラ３６に出力された後、赤外線受発光部３９，Ｒ２３を経由してコントローラ４に入力される。コントローラ４は、そのようにして入力される温度センサ９及び湿度センサ１０の検知出力に基づいて、給湯暖房コントローラ１１、浴槽洗浄コントローラ２２及び空調コントローラ３６の内の少なくとも一つを指示するようにプログラムされている。給湯暖房コントローラ１１には、給湯装置１の湯張り運転等に関する制御プログラムがインストールされている。浴槽洗浄コントローラ２２には、浴槽洗浄装置２の浴槽洗浄運転に関する制御プログラムがインストールされ、空調コントローラ３６には、空調装置３の空調運転に関する制御プログラムがインストールされている。 The controller 4, the hot water supply/heating controller 11, the bathtub cleaning controller 22, and the air conditioning controller 36 are all composed of microcomputers including a CPU, ROM, RAM, A/D converter, interface, and the like. The controller 4 outputs instruction signals of operation switches R22 and R32 operated by the bathroom remote controller R2 and the kitchen remote controller R3 to at least one of the hot water supply and heating controller 11 and the bathtub cleaning controller 22. Detection signals regarding the temperature and humidity in the bathroom BR detected by the temperature sensor 9 and humidity sensor 10 shown in FIG. be done. The controller 4 is programmed to instruct at least one of the hot water supply and heating controller 11, the bathtub cleaning controller 22, and the air conditioning controller 36 based on the detection outputs of the temperature sensor 9 and humidity sensor 10 input in this way. has been done. A control program related to hot water filling operation of the hot water supply device 1 and the like is installed in the hot water supply and heating controller 11 . In the bathtub cleaning controller 22, a control program related to the bathtub cleaning operation of the bathtub cleaning device 2 is installed, and in the air conditioning controller 36, a control program related to the air conditioning operation of the air conditioner 3 is installed.

次に、図３を参照して、コントローラ４が、浴槽洗浄装置２の浴槽洗浄運転の開始指示を受けた時に行う給湯制御及び浴槽洗浄運転可否制御の一形態について説明する。 Next, with reference to FIG. 3, a description will be given of one form of hot water supply control and bathtub cleaning operation enable/disable control performed when the controller 4 receives an instruction to start the bathtub cleaning operation of the bathtub cleaning device 2.

浴室リモコンＲ２又は台所リモコンＲ３に設けられた浴槽洗浄運転指示用の操作スイッチＲ２２ａ，Ｒ３２ａが、ユーザによってＯＮにされ、コントローラ４が浴槽洗浄運転の開始指示を受けると（ＳＴＥＰ１）、コントローラ４は、赤外線受発光部Ｒ２３を介して空調コントローラ３６に換気運転を開始するように指示信号を無線送信する。この指示信号を赤外線受発光部３９を介して受け、空調コントローラ３６は空調装置３の換気運転を開始させる（ＳＴＥＰ２）。空調装置３が換気運転を開始すると、コントローラ４は、図２に示す湿度センサ１０からの検知出力（絶対湿度）が所定値ｘｇ／ｍ３以下であるか否か、又は換気運転の開始から３０分を経過したか否かを判定する（ＳＴＥＰ３）。このＳＴＥＰ３での判定は、浴槽洗浄運転の開始指示を入浴直後に受ける場合、浴室ＢＲ内の湿度が高くなっているため、後に行う、図１に示す浴槽蓋ＢＣの有無判定の精度を上げることを考慮したものである。所定値ｘｇ／ｍ３は、湿度センサ１０の検知機能等を考慮してコントローラ４に予め設定される。 When the operation switches R22a and R32a provided on the bathroom remote controller R2 or the kitchen remote controller R3 for instructing the bathtub cleaning operation are turned on by the user and the controller 4 receives an instruction to start the bathtub cleaning operation (STEP 1), the controller 4 performs the following steps. An instruction signal is wirelessly transmitted to the air conditioning controller 36 via the infrared receiving/emitting unit R23 to start ventilation operation. Upon receiving this instruction signal via the infrared light receiving/emitting section 39, the air conditioning controller 36 starts the ventilation operation of the air conditioner 3 (STEP 2). When the air conditioner 3 starts ventilation operation, the controller 4 determines whether the detection output (absolute humidity) from the humidity sensor 10 shown in FIG. It is determined whether the minutes have elapsed (STEP 3). The determination in STEP 3 is to improve the accuracy of the later determination of the presence or absence of the bathtub lid BC, as shown in FIG. This is taken into consideration. The predetermined value xg/m 3 is preset in the controller 4 in consideration of the detection function of the humidity sensor 10 and the like.

ＳＴＥＰ３はＹＥＳと判定されるまで繰返し行われ、ＹＥＳと判定した時、コントローラ４は、その時点又はその時点から所定時間経過後の湿度センサ１０の検知出力であるａｇ／ｍ３を記憶する（ＳＴＥＰ４）。この後、コントローラ４は、給湯暖房コントローラ１１に湯の生成を指示すると共に、生成した湯を給湯装置１から浴槽洗浄装置２に供給するように指示する。また、コントローラ４は、浴槽洗浄コントローラ２２に給湯装置１から供給される湯を洗浄ノズル２１から浴槽ＢＴ内に供給するように指示する（ＳＴＥＰ５）。このＳＴＥＰ５が、コントローラ４が行う給湯制御である。そして、コントローラ４は、湿度センサ１０から連続的に入力される検知出力であるｂｇ／ｍ３を記憶し、ＳＴＥＰ４で記憶した検知出力ａｇ／ｍ３との差である上昇量ｂ－ａを算出し、ｂ－ａが閾値以上であるか否を判定する（ＳＴＥＰ６）。この判定は、浴槽蓋ＢＣの有無判定に相当し、浴槽ＢＴ内への湯の供給開始から９０秒間継続して行う（ＳＴＥＰ７）。 STEP 3 is repeated until it is determined to be YES, and when it is determined to be YES, the controller 4 stores ag/m 3 which is the detection output of the humidity sensor 10 at that point or after a predetermined period of time has elapsed from that point (STEP 4 ). Thereafter, the controller 4 instructs the hot water supply and heating controller 11 to generate hot water, and also instructs the hot water supply device 1 to supply the generated hot water to the bathtub cleaning device 2. Further, the controller 4 instructs the bathtub cleaning controller 22 to supply hot water supplied from the hot water supply device 1 into the bathtub BT from the cleaning nozzle 21 (STEP 5). This STEP 5 is hot water supply control performed by the controller 4. Then, the controller 4 stores the detection output bg/m 3 that is continuously input from the humidity sensor 10, and calculates the increase b-a that is the difference from the detection output ag/m 3 stored in STEP 4. Then, it is determined whether ba is greater than or equal to a threshold value (STEP 6). This determination corresponds to determining the presence or absence of the bathtub lid BC, and is continuously performed for 90 seconds from the start of supply of hot water into the bathtub BT (STEP 7).

浴槽蓋ＢＣが無い場合、浴槽ＢＴ内に湯が供給されると、浴槽ＢＴから湯気が立ち上り、浴室ＢＲ内の空気に水蒸気が混入して、浴室ＢＲ内の湿度が上昇する。一般的なサイズである約４．１ｍ３の浴室ＢＲで浴槽蓋ＢＣが無く、浴槽ＢＴの上端面が開いている場合、浴槽ＢＴ内に３５℃の湯を供給したときの浴室ＢＲ内の湿度の上昇量は、湯の供給開始から約９０秒後に１ｇ／ｍ３以上になることが実験的に確認された。そこで、ＳＴＥＰ６での閾値を１ｇ／ｍ３に設定している。但し、１ｇ／ｍ３は例示であり、閾値は、浴室ＢＲの大きさ、浴槽ＢＴ内に供給する湯の温度、供給量等によって適宜変更可能である。また、ＳＴＥＰ７の判定継続時間である９０秒間も例示であり、閾値と同様に適宜変更可能である。これらの閾値及び判定継続時間はコントローラ４に予め設定される。 When there is no bathtub lid BC, when hot water is supplied into the bathtub BT, steam rises from the bathtub BT, water vapor mixes into the air in the bathroom BR, and the humidity in the bathroom BR increases. If there is no bathtub lid BC in a bathroom BR of approximately 4.1m3 , which is a common size, and the top end of the bathtub BT is open, the humidity in the bathroom BR when hot water at 35°C is supplied into the bathtub BT. It has been experimentally confirmed that the amount of increase in water becomes 1 g/m 3 or more approximately 90 seconds after the start of hot water supply. Therefore, the threshold value in STEP 6 is set to 1 g/m 3 . However, 1 g/m 3 is an example, and the threshold value can be changed as appropriate depending on the size of the bathroom BR, the temperature of the hot water supplied into the bathtub BT, the supply amount, etc. Further, the determination duration time of STEP 7, 90 seconds, is also an example, and can be changed as appropriate, similar to the threshold value. These threshold values and determination duration times are set in the controller 4 in advance.

そして、給湯制御の開始から９０秒以内に湿度センサ１０の検知出力の上昇量が１ｇ／ｍ３以上になった時、コントローラ４は、浴槽ＢＴの上端面が開いている、即ち、浴槽蓋ＢＣが無いと判定し、浴槽洗浄運転の中止を浴槽洗浄コントローラ２２に指示して浴槽洗浄装置２を停止させる（ＳＴＥＰ８）。この時、通常、浴室リモコンＲ２及び台所リモコンＲ３に内蔵されている報知機を作動させて、浴槽蓋ＢＣが無いことをユーザに報知することができる。報知機によるユーザへの報知は、音、浴室リモコンＲ２及び台所リモコンＲ３の表示部Ｒ２１，Ｒ３１での表示等によって行うことができる。 Then, when the amount of increase in the detection output of the humidity sensor 10 reaches 1 g/ m3 or more within 90 seconds from the start of hot water supply control, the controller 4 determines that the upper end surface of the bathtub BT is open, that is, the bathtub lid BC It is determined that there is no bathtub cleaning operation, and the bathtub cleaning controller 22 is instructed to stop the bathtub cleaning operation, and the bathtub cleaning device 2 is stopped (STEP 8). At this time, the alarm built in the bathroom remote controller R2 and the kitchen remote controller R3 can be activated to notify the user that the bathtub lid BC is missing. The notification to the user by the alarm can be performed by sound, display on the display sections R21 and R31 of the bathroom remote control R2 and the kitchen remote control R3, and the like.

一方、給湯制御の開始から９０秒後にも湿度センサ１０の検知出力の上昇量が１ｇ／ｍ３未満である時には、コントローラ４は、浴槽ＢＴの上端面が閉じている、即ち、浴槽蓋ＢＣが有ると判定して、浴槽洗浄コントローラ２２に浴槽洗浄運転の開始を指示する。この開始指示を受けて浴槽洗浄装置２は浴槽洗浄運転を開始する（ＳＴＥＰ９）。ＳＴＥＰ６以降が、コントローラ４が行う、浴槽蓋ＢＣの有無判定に基づく浴槽洗浄運転可否制御である。 On the other hand, if the increase in the detected output of the humidity sensor 10 is less than 1 g/ m3 even after 90 seconds from the start of hot water supply control, the controller 4 determines that the upper end surface of the bathtub BT is closed, that is, the bathtub lid BC is closed. It is determined that the bathtub cleaning controller 22 is present and instructs the bathtub cleaning controller 22 to start the bathtub cleaning operation. Upon receiving this start instruction, the bathtub cleaning device 2 starts the bathtub cleaning operation (STEP 9). From STEP6 onwards, the controller 4 performs bathtub cleaning operation enable/disable control based on the presence/absence determination of the bathtub lid BC.

尚、コントローラ４が行う給湯制御及び浴槽洗浄運転可否制御は、図３に示す一形態に限定されない。例えば、浴槽洗浄運転の開始指示を受けた時点が入浴直後でない場合、空調装置３を換気運転させるＳＴＥＰ２を省略することができる。この場合、ＳＴＥＰ３は、湿度センサ１０からの検知出力が所定値ｘｇ／ｍ３であるか否かの判定のみに変更するか、又はＳＴＥＰ３を省略する。また、給湯制御を行うことによる湿度センサ１０の検知出力の上昇量を算出するためのＳＴＥＰ４は、必ずしも給湯制御であるＳＴＥＰ５の前段に設ける必要はなく、ＳＴＥＰ５と同時に又はＳＴＥＰ５から所定時間後に設けることもできる。即ち、ＳＴＥＰ４は、ＳＴＥＰ６以降の浴槽洗浄運転可否制御を支障なく行うことができる、ＳＴＥＰ６の前段に設ければよい。 Note that the hot water supply control and bathtub cleaning operation availability control performed by the controller 4 are not limited to the one form shown in FIG. 3 . For example, if the instruction to start the bathtub cleaning operation is not received immediately after taking a bath, STEP 2 in which the air conditioner 3 is operated for ventilation can be omitted. In this case, STEP 3 is changed to only determine whether the detection output from the humidity sensor 10 is the predetermined value xg/m 3 or STEP 3 is omitted. Furthermore, STEP 4 for calculating the amount of increase in the detection output of the humidity sensor 10 due to hot water supply control does not necessarily need to be provided before STEP 5, which is hot water supply control, but may be provided at the same time as STEP 5 or after a predetermined time from STEP 5. You can also do it. That is, STEP 4 may be provided before STEP 6 so that the bathtub cleaning operation permission control after STEP 6 can be performed without any trouble.

本実施形態では、浴室システムＢＳに既設の湿度センサ１０の検知出力の上昇量に基づいて浴槽蓋ＢＣの有無判定を行うことができ、その判定結果によって浴槽洗浄運転を開始又は中止させることができる。従って、感熱センサを別途設置することなく既存のシステムを利用して、浴槽蓋ＢＣの有無判定と浴槽洗浄装置の制御とを行うことができる。また、給湯制御に先立って空調運転を行い、浴室ＢＲの空気を吸込み口３５１を介して通気路３３内に吸い込むため、通気路３３内で吸込み口３５１の近傍に設けられた湿度センサ１０による湿度検知が迅速且つ正確になる。更に、空調運転は換気運転であるため、浴室ＢＲ内を換気した後の浴室ＢＲ内の湿度は低下し、入浴直後に浴槽洗浄運転の開始指示を受けても、湿度センサ１０の検知出力の上昇量が明確になり、コントローラ４による浴槽蓋ＢＣの有無判定が正確になる。 In this embodiment, the presence or absence of the bathtub lid BC can be determined based on the amount of increase in the detection output of the humidity sensor 10 installed in the bathroom system BS, and the bathtub cleaning operation can be started or stopped based on the determination result. . Therefore, the existing system can be used to determine the presence or absence of the bathtub lid BC and to control the bathtub cleaning device without separately installing a heat-sensitive sensor. In addition, since the air conditioning operation is performed prior to hot water supply control and the air from the bathroom BR is sucked into the ventilation path 33 through the suction port 351, the humidity is detected by the humidity sensor 10 provided in the ventilation path 33 near the suction port 351. Detection becomes faster and more accurate. Furthermore, since the air conditioning operation is a ventilation operation, the humidity in the bathroom BR decreases after the interior of the bathroom BR is ventilated, and even if an instruction to start the bathtub cleaning operation is received immediately after taking a bath, the detection output of the humidity sensor 10 increases. The amount becomes clear, and the determination of the presence or absence of the bathtub lid BC by the controller 4 becomes accurate.

以上、本発明を一実施形態に関して説明したが、本発明は上記実施形態に限定されない。例えば、給湯制御に際し、湯を、浴槽洗浄装置２からではなく、給湯装置１から浴槽ＢＴ内に供給することができる。また、換気運転を乾燥運転に替えることができる。この場合、浴室ＢＲ内を乾燥した後の浴室ＢＲ内の湿度は換気運転後よりも低下するため、湿度センサ１０の検知出力の上昇量がより明確になり、コントローラ４による浴槽蓋ＢＣの有無判定がより正確になる。尚、空調装置３には、温水式若しくは電気式の暖房装置又は冷暖房装置のいずれのものも採用することができる。また、空調コントローラ３６は、コントローラ４に有線接続してもよい。更に、本発明における空調装置は、上記実施形態の空調装置３に限定されず、換気ファンが通気路内に設けられるものであってもよい。 Although the present invention has been described above with respect to one embodiment, the present invention is not limited to the above embodiment. For example, during hot water supply control, hot water can be supplied into the bathtub BT from the hot water supply device 1 instead of from the bathtub cleaning device 2. Furthermore, ventilation operation can be replaced with drying operation. In this case, since the humidity in the bathroom BR after drying the bathroom BR is lower than that after the ventilation operation, the amount of increase in the detection output of the humidity sensor 10 becomes more clear, and the controller 4 determines the presence or absence of the bathtub lid BC. becomes more accurate. Note that the air conditioner 3 may be a hot water type or electric type heating device or air conditioning device. Further, the air conditioning controller 36 may be connected to the controller 4 by wire. Furthermore, the air conditioner according to the present invention is not limited to the air conditioner 3 of the embodiment described above, and a ventilation fan may be provided in the ventilation path.

そして、浴室システムＢＳには、湯張り運転の前に浴槽洗浄運転を行う自動湯張り運転が設定される場合がある。この場合、コントローラ４には、浴室リモコンＲ２及び台所リモコンＲ３の操作スイッチＲ２２，Ｒ３２に設けられる、自動湯張り運転を指示する操作スイッチがユーザによってＯＮにされる時、浴槽洗浄運転の開始指示を受けた時と同様に、給湯制御と浴槽洗浄運転可否制御とを行うように設定することができる。 The bathroom system BS may be set to an automatic hot water filling operation in which a bathtub cleaning operation is performed before the hot water filling operation. In this case, when the user turns on the operation switches R22 and R32 of the bathroom remote control R2 and the kitchen remote control R3, which instruct the automatic hot water filling operation, the controller 4 issues an instruction to start the bathtub cleaning operation. In the same way as when receiving the request, settings can be made to perform hot water supply control and bathtub cleaning operation availability control.

また、本発明におけるコントローラは、浴槽洗浄運転の開始指示を受けた時に給湯制御及び浴槽洗浄運転可否制御を行うことができるように構成されていれば、コントローラ４に限定されない。例えば、給湯暖房コントローラ１１、浴槽洗浄コントローラ２２及び空調コントローラ３６の内のいずれか一つを本発明におけるコントローラとすることができる。 Further, the controller in the present invention is not limited to the controller 4 as long as it is configured to be able to perform hot water supply control and control over whether or not the bathtub cleaning operation is possible when receiving an instruction to start the bathtub cleaning operation. For example, any one of the hot water supply and heating controller 11, the bathtub cleaning controller 22, and the air conditioning controller 36 can be used as the controller in the present invention.
