この考案は風呂の湯沸かしを自動的に行う自動給湯装置に関し、詳しくは予約 機能を備えた自動給湯装置に関する。 This invention is related to an automatic water heater that automatically boils water for baths.For more information, please make a reservation. Regarding an automatic hot water supply device with functions.
【０００２】0002
この種の自動給湯装置の場合、風呂の湯沸かしは、通常、浴槽に若干低めの温 度の湯を所定量供給する湯張り操作と、この湯張り操作で浴槽内に供給された湯 を所望の焚上がり温度まで追焚きする追焚き操作とによって行われるようになっ ている。 With this type of automatic water heater, the bath water is usually heated at a slightly lower temperature in the bathtub. A hot water filling operation that supplies a predetermined amount of hot water, and a hot water that is supplied into the bathtub by this hot water filling operation. This is now done by reheating the heat to the desired temperature. ing.
【０００３】 ところでこのような自動給湯装置において風呂の湯沸かしを予約する場合、従 来にあっては、湯張り操作の開始時刻、即ち湯沸かしを実際に開始する時刻をタ イマで設定するようにしている。0003 By the way, when making a reservation to heat water for a bath using an automatic water heater like this, Nowadays, the start time of the water filling operation, that is, the time when the water boiling actually starts, is set as a timer. I try to set it up now.
【０００４】 しかしながらこのような予約方法では、望みの時刻に風呂を焚き上げるように 予約するとき、その入浴希望時刻から湯沸かしに要する時間を一々逆算してタイ マを設定する必要があり、また湯沸かしに要する時間を経験的に知っている者で ないとタイマを適正に設定できないといった問題があった。0004 However, with this reservation method, it is not possible to heat the bath at the desired time. When making a reservation, calculate backwards the time required to boil the water from your desired bathing time. A person who knows from experience the time required to boil water. Without it, there was a problem that the timer could not be set properly.
【０００５】 これに対し、実開昭６３−３７９５５号公報において、前回の湯沸かしに要し た実際の時間をメモリに記憶しておき、タイマの設定時刻からその記憶した時間 を差し引いた時刻に湯張り操作を開始して、タイマの設定時刻に風呂が焚き上が るようにする方法が提案されている。この方法によれば、タイマの設定時刻がそ のまま風呂の焚上がり時刻を表すため、タイマの設定操作が容易となり、また湯 沸かしの所要時間を知らない者でも、湯沸かしの開始時刻を適正に設定できるよ うになる。[0005] On the other hand, in Japanese Utility Model Application Publication No. 63-37955, it is reported that The actual time that was set is stored in memory, and the memorized time is calculated from the timer setting time. The bath will be heated at the time set on the timer, and the bath will be heated at the time set on the timer. A method has been proposed to make this possible. According to this method, the set time of the timer Since it indicates the time when the hot bath is finished, it is easy to set the timer, and the timer is easy to set. Even people who don't know how long it takes to boil water can set the appropriate time to start boiling water. I'm going to growl.
【０００６】[0006]
しかしながらこの方法の場合、タイマの設定時刻が風呂の実際の焚上がり時刻 と一致するのは、あくまでも浴槽の湯張り量や風呂の設定焚上がり温度が前回と 同じ場合であり、使用者のその時々の気分や最初に入浴する者の個人差などによ ってそれら設定値が変更されたような場合には、風呂の実際の焚上がり時刻がタ イマの設定時刻から大きくかけ離れてしまうといった問題がある。 However, with this method, the timer setting time is the actual time when the bath is heated. The reason for this is that the amount of hot water in the bathtub and the temperature at which the bath is heated are the same as before. This is the same case, and it depends on the user's mood at the time and the individual differences of the person taking the bath for the first time. If those settings have been changed, the actual heating time of the bath will be changed. There is a problem in that the time is far from the currently set time.
【０００７】[0007]
本考案の自動給湯装置はこのような課題を解決するために案出されたものであ り、その要旨は、浴槽内に供給される湯の流量と設定された望みの浴槽湯量とか ら所要湯張り時間を算出するとともに、設定された望みの浴槽湯温と湯張り温度 から所要追焚き時間を算出し、使用者により設定された風呂焚完了時刻よりそれ ら所要湯張り時間及び所要追焚き時間を差し引いた時刻に湯張りを開始させる演 算制御手段を有していることにある。 The automatic water heater of this invention was devised to solve these problems. The gist of this is that the flow rate of hot water supplied into the bathtub and the desired amount of hot water in the bathtub are In addition to calculating the required bath water filling time, set the desired bath water temperature and bath temperature. The required reheating time is calculated from the bath heating completion time set by the user. An operation that starts filling the hot water at the time after subtracting the required time for filling the hot water and the required reheating time. The reason is that it has a calculation control means.
【０００８】 ［作用及び考案の効果］ 湯張り操作と追焚き操作によって湯沸かしをする自動給湯装置の場合、湯沸か しに要する時間ｔ3は、湯張り操作に要する時間（所要湯張り時間）ｔ1と追焚き 操作に要する時間（所要追焚き時間）ｔ2とを加えた時間として求めることがで きる。そしてこの場合、所要湯張り時間ｔ1は、設定浴槽湯量（望みの浴槽湯量 ；湯張り量）Ｖ2と湯張り時の湯の供給量（給湯速度）ｖが分かれば、ｔ1＝Ｖ2 ／ｖとして求めることができ、また所要追焚き時間ｔ2は、湯張り後の浴槽湯温 Ｋ1と設定焚上がり浴槽湯温（望みの浴槽湯温）Ｋ2が分かれば、ｔ2＝（Ｋ2−Ｋ 1 ）Ｖ2／Ｑ（ただしＱは給湯装置の単位時間当たりの追焚き能力）として求める ことができる。[0008] [Effects of actions and ideas] In the case of an automatic water heater that heats water by filling and reheating the water, The time t required to3is the time required for hot water filling operation (required hot water filling time) t1and rekindle the fire Time required for operation (required reheating time) t2can be calculated as the time plus Wear. In this case, the required filling time t1is the set bath water volume (desired bath water volume) ;Hot water filling amount)V2If you know the amount of hot water supplied (hot water supply speed) v when filling the hot water, then t1=V2 /v, and the required reheating time t2is the bathtub water temperature after filling K1and set hot tub water temperature (desired bath water temperature) K2If you know, t2=(K2-K 1 )V2/Q (where Q is the reheating capacity of the water heater per unit time) be able to.
【０００９】 本考案の自動給湯装置はこのような知見に基づいて為されたもので、浴槽への 給湯速度ｖと設定浴槽湯量（湯張り量）Ｖ2とから所要湯張り時間ｔ1を求めると 共に、湯張り後の浴槽湯温Ｋ1（一般に予め一定に設定されている）と設定焚上 がり浴槽湯温Ｋ2とから所要追焚き時間ｔ2を求め、使用者による設定予約時刻Ｔ 2 からそれら所要湯張り時間ｔ1及び所要追焚き時間ｔ2（所要湯沸かし時間ｔ3） を差し引いた時刻Ｔ0に浴槽の湯張り操作を開始させ、これによって風呂の焚上 がり時刻を設定予約時刻Ｔ2に一致させるものである。[0009] The automatic water heater of the present invention was created based on this knowledge, and it Hot water supply speed v and set bathtub hot water amount (hot water filling amount) V2Required boiling time t1If you ask for Both are the bathtub water temperature K after filling the bathtub.1(generally set to a certain value in advance) and setting firing Gari bath water temperature K2Required reheating time t2, and the reservation time T set by the user. 2 The required hot water filling time t1and required reheating time t2(Required boiling time t3) time T after subtracting0starts filling the bathtub with hot water, which causes the bath to start heating. Set the departure timeReservation time T2It is made to match.
【００１０】 本考案では、所要湯張り時間ｔ1及び所要追焚き時間ｔ2を設定浴槽湯量Ｖ2及 び設定焚上がり浴槽湯温Ｋ2に応じ、浴槽への給湯流量等に基づいて計算によっ て求めるものであるため、それら設定浴槽湯量（湯張り量）Ｖ2や設定焚上がり 浴槽湯温Ｋ2を好みに応じて自由に変えることができ、この場合において風呂の 焚上がり時刻を設定予約時刻Ｔ2に常に精度良く一致させることができる。[0010] In the present invention, the required hot water filling time t 1 and the required reheating time t 2 are calculated according to the set bathtub hot water volume V 2 and the set heated bathtub water temperature K 2 based on the flow rate of hot water to the bathtub, etc. Therefore, you can freely change the set bathtub hot water volume (hot water filling amount) V 2 and the set bathtub hot water temperature K 2 according to your preference. 2 can always be accurately matched.

以下本考案の実施例を図面に基づいて詳しく説明する。 図１において１０は給湯器であって、給湯器本体１２を主体に構成され、２本 の配管１４，１６を介して浴槽１８に接続されている。また同図中２０は給湯器 １０の制御器であり、給湯器１０を操作するための浴槽用リモコン２２及び給湯 用リモコン２４がこれに接続されている。 Embodiments of the present invention will be described in detail below with reference to the drawings. In FIG. 1, 10 is a water heater, which is mainly composed of a water heater main body 12, and has two water heaters. It is connected to the bathtub 18 via piping 14, 16. Also, 20 in the same figure is a water heater 10 controller, and a bathtub remote control 22 for operating the water heater 10 and a hot water supply. A remote control 24 is connected to this.
【００１２】 給湯器１０には給水継手２６から水道水が供給されるようになっており、この 水道水が減圧弁２８で減圧された後、給湯器本体１２の缶体３０及び混合弁３６ に分配されるようになっている。0012 Tap water is supplied to the water heater 10 from a water supply joint 26. After the tap water is depressurized by the pressure reducing valve 28, the can body 30 of the water heater main body 12 and the mixing valve 36 It is designed to be distributed to
【００１３】 給湯器本体１２の缶体３０に供給された水道水はバーナー３２にて所定の比較 的高い温度（通常８０℃程度）に加熱された後、出湯分配管３４を通じて缶体３ ０から流出され、混合弁３６に至るものと継手３８に至るものとに分配される。[0013] The tap water supplied to the can body 30 of the water heater main body 12 is subjected to a predetermined comparison using the burner 32. After being heated to a high temperature (usually around 80°C), the hot water is poured into the can body 3 through the hot water distribution pipe 34. 0 and is distributed to the mixing valve 36 and the joint 38.
【００１４】 混合弁３６は、缶体３０からのお湯と減圧弁２８からの水道水とを混合して通 常の入浴温度（４５℃程度）よりも若干低い一定温度、例えば３８℃程度のお湯 を作るもので、流量センサ３９を介して電磁弁４０に接続されている。[0014] The mixing valve 36 mixes hot water from the can body 30 and tap water from the pressure reducing valve 28 and passes the mixture. Hot water at a constant temperature, for example around 38°C, slightly lower than the usual bathing temperature (around 45°C) It is connected to a solenoid valve 40 via a flow rate sensor 39.
【００１５】 電磁弁４０は浴槽１８の湯張り時に開き、追焚き時に閉じるように制御される もので、混合弁３６で作られたお湯はこの電磁弁４０の開弁時、即ち浴槽１８の 湯張り時に逆止弁４２を介して両搬送分岐部４４に供給され、この両搬送分岐部 ４４から逆止弁４６，搬送管４８及び配管１６の第一経路と、逆止弁５０，搬送 管５２，循環ポンプ５４，搬送管５６及び配管１４の第二経路とを経て浴槽１８ に供給される。尚このとき、循環ポンプ５４は停止状態に維持される。[0015] The solenoid valve 40 is controlled to open when the bathtub 18 is filled with hot water and close when reheating the bathtub 18. The hot water produced by the mixing valve 36 is released when the solenoid valve 40 is opened, that is, when the bathtub 18 is heated. When filling hot water, it is supplied to both conveyance branch sections 44 via the check valve 42, and the two conveyance branch sections 44 to the check valve 46, the conveying pipe 48, and the first route of the piping 16, the check valve 50, and the conveying pipe The bathtub 18 via the pipe 52, the circulation pump 54, the conveying pipe 56, and the second route of the piping 14. supplied to At this time, the circulation pump 54 is maintained in a stopped state.
【００１６】 一方電磁弁４０の閉弁時において、循環ポンプ５４が作動されると浴槽１８内 に張られた湯が追焚きされる。即ち循環ポンプ５４が作動されると、浴槽１８内 の湯が配管１６，搬送管４８，搬送管５８を介して給湯器本体１２の缶体３０内 に配された循環コイル６０に導かれ、この循環コイル６０の通過時に缶体３０内 の高温湯にて間接加熱される。そしてこの循環コイル６０で加熱された湯が搬送 管６２，５２，循環ポンプ５４，搬送管５６及び配管１４を経て浴槽１８に還流 され、浴槽１８内の湯が追焚きされることとなる。[0016] On the other hand, when the solenoid valve 40 is closed, when the circulation pump 54 is activated, the inside of the bathtub 18 is The hot water filled with water is reheated. That is, when the circulation pump 54 is activated, the inside of the bathtub 18 The hot water enters the can body 30 of the water heater main body 12 via the piping 16, the conveying pipe 48, and the conveying pipe 58. When the circulating coil 60 passes through the can body 30, the It is heated indirectly using hot water. The hot water heated by this circulation coil 60 is then transported Returns to bathtub 18 via pipes 62, 52, circulation pump 54, conveyance pipe 56, and piping 14 As a result, the hot water in the bathtub 18 is reheated.
【００１７】 尚循環コイル６０の前後の流路は両搬送分岐部４４を介して接続された状態と なっているが、これらの間は逆止弁４６，５０によって遮断される。また本例の 場合、給湯器１０の搬送管４８上にサーミスタ６４が設けられ、浴槽１８内に張 られた湯の温度がこのサーミスタ６４で検知されるようになっている。[0017] Note that the flow paths before and after the circulation coil 60 are connected via both conveyance branch parts 44. However, the gap between them is blocked by check valves 46 and 50. Also, in this example In this case, a thermistor 64 is provided on the conveying pipe 48 of the water heater 10, and a thermistor 64 is installed inside the bathtub 18. The temperature of the heated hot water is detected by this thermistor 64.
【００１８】 ところで本例の給湯器１０の場合、前記浴槽用リモコン２２に湯張り量の設定 部と沸き上がり湯温の設定部が設けられており、また前記制御器２０にタイマが 設けられるとともに、浴槽用リモコン２２に該タイマの設定部が設けられている 。そして制御器２０には、その浴槽用リモコン２２で設定された湯張り量、沸き 上がり湯温及びタイマの設定時刻に基づいてタイマの設定時刻に風呂を焚き上げ るようにする制御機能が付与されている。[0018] By the way, in the case of the water heater 10 of this example, the hot water filling amount can be set on the bathtub remote control 22. The controller 20 is provided with a setting section for setting the boiling water temperature and a boiling water temperature, and a timer is provided in the controller 20. In addition, the bathtub remote control 22 is provided with a setting section for the timer. . The controller 20 displays the amount of hot water set with the bathtub remote control 22, and the boiling temperature. The bath is heated at the time set on the timer based on the rising water temperature and the time set on the timer. A control function is provided to ensure that
【００１９】 図２はこの制御器２０の制御機能を示すフローチャートであり、以下このフロ ーチャートに従ってタイマによる予約時の給湯器１０の作動を説明する。 即ち風呂の湯沸かしを予約する場合には、浴槽用リモコン２２で湯張り量（設 定浴槽湯量）Ｖ2、焚上がり温度Ｋ2を設定するとともに、風呂の焚上がり時刻Ｔ 2 をタイマ設定する。これらを設定してタイマが作動すると、先ずステップＳ１ が実行され、浴槽１８の所要湯張り時間ｔ1と所要追焚き時間ｔ2の和としての風 呂の焚上り所要時間ｔ3が求められる。[0019] FIG. 2 is a flowchart showing the control function of this controller 20. - The operation of the water heater 10 at the time of reservation by the timer will be explained according to the chart. In other words, when reserving water heating for a bath, you can use the bathtub remote control 22 to change the amount of hot water (set amount). Fixed bath water volume) V2, firing temperature K2In addition to setting the bath heating time T 2 Set the timer. When these settings are set and the timer is activated, first step S1 is executed, and the required time for filling the bathtub 18 with hot water t1and the required reheating time t2wind as the sum of Required time for burning ro3is required.
【００２０】 ここで所要湯張り時間ｔ1は、浴槽用リモコン２２による設定浴槽湯量Ｖ2と、 前回の湯張り時に流量センサ３９で検知された浴槽１８への給湯速度ｖとから、 ｔ1＝Ｖ2／ｖとして求められるものであり、また所要追焚き時間ｔ2は、湯張り 後の浴槽１８内の湯温Ｋ1，設定焚上がり湯温Ｋ2，設定浴槽湯量Ｖ2及び給湯器 １０の単位時間当たりの追焚き能力Ｑとから、ｔ2＝（Ｋ2−Ｋ1）Ｖ2／Ｑとして 求められるものであって、所要湯張り時間ｔ1及び所要追焚き時間ｔ2はそれぞれ そのときの設定浴槽湯量Ｖ2及び設定焚上がり湯温Ｋ2に対応した値として求めら れる。尚湯張り後の浴槽１８内の湯温Ｋ1は、混合弁３６から浴槽１８に供給さ れる湯温に等しく、予め所定の温度に設定されている。[0020] Here, the required hot water filling time t 1 is calculated from the bathtub hot water volume V 2 set by the bathtub remote control 22 and the hot water supply speed v to the bathtub 18 detected by the flow rate sensor 39 during the previous hot water filling, t 1 = It is determined as V 2 /v, and the required reheating time t 2 is calculated based on the hot water temperature K 1 in the bathtub 18 after filling with hot water, the set hot water temperature K 2 , the set bath water volume V 2 and the water heater 10. From the reheating capacity Q per unit time, it is obtained as t 2 = (K 2 - K 1 )V 2 /Q, and the required hot water filling time t 1 and the required reheating time t 2 are respectively at that time. It is determined as a value corresponding to the set bathtub hot water volume V 2 and the set hot water temperature K 2 . The temperature K 1 of hot water in the bathtub 18 after filling with hot water is equal to the temperature of hot water supplied to the bathtub 18 from the mixing valve 36, and is set in advance to a predetermined temperature.
【００２１】 焚上がり所要時間ｔ3が算出されると、続くＳ２において、浴槽用リモコン２ ２によるタイマの設定時刻Ｔ2から前記焚上がり所要時間ｔ3（＝ｔ1＋ｔ2）が差 し引かれ、風呂の湯沸かしを開始する時刻Ｔ0（＝Ｔ2−ｔ3）が求められる。そ してその時刻Ｔ0と実際の時刻とが比較されて、実際の時刻がその時刻Ｔ0に達す ると、制御器２０から電磁弁４０に弁開信号が出力されて電磁弁４０が開かれ、 浴槽１８への湯張り操作が開始される（Ｓ３）。またこの湯張り操作の開始後、 次回の湯張り時の所要湯張り時間ｔ1を算出するために、流量センサ３９での検 知信号に基づいて浴槽１８への給湯速度ｖが求められ、メモリに記憶される（Ｓ ４）。[0021] Once the time required for heating up t 3 is calculated, in the subsequent S2, the required time t 3 (=t 1 +t 2 ) for heating is subtracted from the time T 2 set on the timer by the bathtub remote controller 22; The time T 0 (=T 2 −t 3 ) at which to start heating water in the bath is determined. Then, the time T0 and the actual time are compared, and when the actual time reaches the time T0 , a valve opening signal is output from the controller 20 to the solenoid valve 40, the solenoid valve 40 is opened, and the bathtub is opened. The operation of filling water to No. 18 is started (S3). Furthermore, after the start of this hot water filling operation, in order to calculate the required hot water filling time t1 for the next hot water filling, the hot water supply speed v to the bathtub 18 is determined based on the detection signal from the flow rate sensor 39, and is stored in the memory. It is stored (S4).
【００２２】 ステップＳ５では、流量センサ３９の検知信号に基づいて湯張り操作開始後の 湯張り量、即ち湯張り操作を開始してから浴槽１８に実際に供給された流量Ｖが リアルタイムで測定され、この測定湯量（現湯張り量）Ｖが設定浴槽湯量Ｖ2と 比較される。そしてこの浴槽１８内の実際の湯張り量Ｖが設定浴槽湯量Ｖ2に達 すると、制御器２０から電磁弁４０に閉信号が送られて電磁弁４０が閉じられ、 浴槽１８への給湯が停止されて湯張り操作が完了する（Ｓ６）。尚この湯張り操 作の所要時間は、気温などに大幅な変動が無い限り、前回の湯張り時の浴槽１８ への給湯量と今回のそれとが一致することとなるため、前記ステップＳ１で求め た所要湯張り時間ｔ1と精度良く一致することとなる。In step S5, the amount of hot water filled after starting the hot water filling operation, that is, the flow rate V actually supplied to the bathtub 18 after starting the hot water filling operation, is measured in real time based on the detection signal of the flow rate sensor 39. , this measured hot water amount (current hot water filling amount) V is compared with the set bathtub hot water amount V 2 . When the actual amount of hot water in the bathtub 18 reaches the set bathtub hot water amount V2 , a close signal is sent from the controller 20 to the solenoid valve 40, the solenoid valve 40 is closed, and hot water supply to the bathtub 18 is stopped. Then, the hot water filling operation is completed (S6). The time required for this hot water filling operation was calculated in step S1 above, since the amount of hot water supplied to the bathtub 18 during the previous hot water filling operation will be the same as the current amount, unless there is a significant change in temperature etc. This accurately matches the required hot water filling time t1 .
【００２３】 湯張り操作が完了すると、引き続いて追焚き操作が行われる。即ちステップＳ ６が完了するとステップＳ７が実行され、サーミスタ６４による浴槽１８内の湯 温の検知温度Ｋが設定焚上がり湯温Ｋ2に達したか否かが判断される。そしてこ のサーミスタ６４の検知温度Ｋが設定焚上がり湯温Ｋ2より低い間、循環ポンプ ５４が作動されて浴槽１８内の湯が追焚きされ、サーミスタ６４の検知温度Ｋが 設定焚上がり湯温Ｋ2に達した後、循環ポンプ５４の作動が停止されて、追焚き が完了する。即ちこれによって風呂の湯沸かしが完了し、浴槽１８内に設定湯量 Ｖ2，設定温度Ｋ2の湯が満たされて入浴可能な状態となる。[0023] When the hot water filling operation is completed, a reheating operation is subsequently performed. That is, when step S6 is completed, step S7 is executed, and it is determined whether the temperature K detected by the thermistor 64 of the water temperature in the bathtub 18 has reached the set hot water temperature K2 . While the temperature K detected by the thermistor 64 is lower than the set heated water temperature K 2 , the circulation pump 54 is operated to reheat the hot water in the bathtub 18, and the temperature K detected by the thermistor 64 reaches the set heated water temperature K 2 . After reaching this point, the operation of the circulation pump 54 is stopped and reheating is completed. That is, this completes the heating of the bath water, and the bathtub 18 is filled with hot water at the set amount of water V 2 and the set temperature K 2 , making it possible to take a bath.
【００２４】 尚この追焚き操作の実際の所要時間は、前記湯張り操作の実際の所要時間がス テップＳ１での所要湯張り時間ｔ1と精度良く一致するのと同様、湯張り後の浴 槽１８内の湯温、即ち混合弁３６から浴槽１８に供給される湯張り時の湯温がＫ 1 と一定で、給湯器１０の単位時間当たりの追焚き能力Ｑも一定であることから 、、前記ステップＳ１での所要追焚き時間ｔ2に精度良く一致する。[0024] The actual time required for this reheating operation is based on the actual time required for the above-mentioned hot water filling operation. Required hot water filling time t in step S11As well as the accurate agreement with The temperature of the water in the bathtub 18, that is, the temperature of the water supplied from the mixing valve 36 to the bathtub 18 when the bathtub 18 is filled with water, is K. 1 is constant, and the reheating capacity Q per unit time of the water heater 10 is also constant. ,,required reheating time t in step S12matches accurately.
【００２５】 このように本例の給湯器１０の場合、湯張り操作の実際の所要時間が設定浴槽 湯量Ｖ2に応じて算出された所要湯張り時間ｔ1と精度良く一致するとともに、追 焚き操作の実際の所要時間が同じく設定焚上がり湯温Ｋ2に応じて算出された所 要追焚き時間ｔ2と精度良く一致するものであるところから、設定浴槽湯量Ｖ2や 設定焚上がり湯温Ｋ2の設定変更の有無に拘らず、風呂の湯沸かし完了時刻がタ イマの設定時刻に精度良く一致することとなる。As described above, in the case of the water heater 10 of this example, the actual time required for hot water filling operation accurately matches the required hot water filling time t 1 calculated according to the set bathtub hot water volume V 2 , and the reheating Since the actual time required for the operation accurately matches the required reheating time t 2 calculated according to the set hot water temperature K 2 , the set bath water volume V 2 and the set hot water temperature K 2 are Regardless of whether or not the settings have been changed, the time at which the bath water is heated will accurately match the time set on the timer.
【００２６】 以上本考案の一実施例を詳細に説明したが、本考案はこれに限定されるもので はない。 例えば前例では、所要湯張り時間ｔ1を求める際の湯張り速度ｖとして前回の 湯張り時の給湯速度を用いていたが、複数回の湯張り操作で得られた複数の給湯 速度の平均値を給湯速度ｖとして用いてもよく、また季節等に応じて経験的に求 めた複数の給湯速度からその時の条件に応じて選択したものを給湯速度ｖとして 選択するようにしてもよく、更には給湯速度を比較的小さく設定して、季節の変 化に拘らず一定の給湯速度を得られるようにし、その小さく抑制した給湯速度を 給湯速度ｖとして所要湯張り時間ｔ1の算出に用いてもよい。Although one embodiment of the present invention has been described above in detail, the present invention is not limited thereto. For example, in the previous example, the hot water supply speed at the previous hot water filling was used as the hot water filling speed v when calculating the required hot water filling time t1 , but the average value of multiple hot water feeding speeds obtained from multiple hot water filling operations was may be used as the hot water supply rate v, or a hot water supply rate selected from a plurality of hot water supply rates empirically determined depending on the season etc. according to the conditions at that time may be selected as the hot water supply rate v; The hot water supply rate may be set relatively low so that a constant hot water supply rate can be obtained regardless of seasonal changes, and the suppressed hot water rate may be used as the hot water supply rate v to calculate the required hot water filling time t1 . .
【００２７】 また前例では、混合弁３６からの湯張り時の給湯温度がＫ1で一定としたが、 この混合弁３６からの給湯温度を調節できるようにしたものでは、その調節によ って設定した湯張り時の給湯温度をＫ1として採用することが可能であり、また そのような給湯温度の変更がないような場合には、前回の湯張り完了時の浴槽内 湯温をサーミスタ６４で測定，記憶して、その測定、記憶値を湯張り完了時の温 度Ｋ1として採用することができる。Furthermore, in the previous example, the temperature of hot water supplied from the mixing valve 36 during filling was constant at K 1 , but in the case where the temperature of hot water supplied from this mixing valve 36 can be adjusted, the set hot water temperature is It is possible to use the hot water supply temperature at the time of filling the bathtub as K1 , and if there is no such change in the hot water supply temperature, the hot water temperature in the bathtub at the time of the previous filling completion can be measured and stored using the thermistor 64. Then, the measured and stored value can be used as the temperature K 1 at the time of completion of filling the hot water.
【００２８】 この外本考案は、流量検知手段や温度検知手段として例示以外の構成のものを 採用できるなど、その主旨を逸脱しない範囲において、当業者の有する知識に基 づき様々な変更を施した形態で構成できる。[0028] This invention does not apply to configurations other than those illustrated as flow rate detection means or temperature detection means. Based on knowledge possessed by a person skilled in the art, to the extent that it can be adopted and does not deviate from the gist of the It can be configured with various modifications.
