ところで、近年、総合病院や介護施設などでは、従業者の労働負担の軽減を図るべく、上記のような湯張り機能および浴槽洗浄機能を備えた風呂システムの導入の要望が高まっている。しかしながら、このような大型施設の場合、要求に応じて速やかに各温水利用先へ所望温度の湯を供給できるよう、施設内の給湯配管に対して給湯器から常に一定温度の湯を循環供給させておく所謂即湯式の給湯システムが広く導入されており、給湯器に湯張り運転を実行する機能までは搭載されていない。そのため、上記従来の風呂システムを導入する場合は、既設の給湯器の取り替えも必要であった。   By the way, in recent years, in general hospitals and nursing facilities, there is an increasing demand for introducing a bath system having the above-described water filling function and bathtub cleaning function in order to reduce the labor burden on employees. However, in the case of such a large facility, in order to promptly supply hot water of a desired temperature to each hot water use destination, it is necessary to circulate hot water of a constant temperature from the water heater to the hot water supply pipes inside the facility. The so-called instant hot water supply system has been widely introduced, and the hot water supply device does not have a function of performing a hot water filling operation. Therefore, when introducing the above-mentioned conventional bath system, it was necessary to replace the existing water heater.

本発明は、上記課題を鑑みてなされたものであり、その目的は、湯張り機能および浴槽洗浄機能を備えた風呂システムを既設の給湯器を用いて構築可能な、汎用性の高い浴槽洗浄装置を提供することにある。   The present invention has been made in view of the above problems, and an object thereof is a highly versatile bathtub cleaning device capable of constructing a bath system having a water filling function and a bathtub cleaning function using an existing water heater. To provide.

本発明は、熱源機で加熱生成された湯を浴槽に設けられた洗浄ノズルへ導く洗浄出湯管路と、洗浄出湯管路からの湯の導出量を調整可能な湯量調整部と、洗浄液を貯留可能な洗浄液タンクと、洗浄液タンク内の洗浄液を洗浄出湯管路へ導く洗浄液混合管路と、洗浄液混合管路から洗浄出湯管路への洗浄液の導出量を調整可能な洗浄液量調整部とを備えた浴槽洗浄装置であって、洗浄出湯管路から分岐して配設され、洗浄出湯管路に供給される湯を浴槽給湯口へ導く湯張り出湯管路と、洗浄出湯管路から湯張り出湯管路への湯の流通を遮断可能な流路切替部とを備え、洗浄出湯管路における湯張り出湯管路との分岐部より下流側には通水を遮断可能な開閉弁が設けられず、湯張り出湯管路に、前記流路切替部として通水を遮断可能な開閉弁が設けられたものである。 The present invention provides a cleaning hot water outlet conduit for guiding hot water generated by a heat source device to a cleaning nozzle provided in a bath, a hot water amount adjusting unit capable of adjusting the amount of hot water discharged from the cleaning hot water outlet conduit, and a cleaning liquid reservoir. It is equipped with a possible cleaning liquid tank, a cleaning liquid mixing conduit that guides the cleaning liquid in the cleaning liquid tank to the cleaning hot water discharge conduit, and a cleaning liquid amount adjustment unit that can adjust the amount of the cleaning liquid that is drawn from the cleaning liquid mixing conduit to the cleaning hot water discharge conduit. A bathtub cleaning device, which is provided so as to branch from the cleaning hot water discharge pipe line and guides the hot water supplied to the wash hot water discharge pipe line to the bathtub hot water supply port and the hot water discharge pipe line from the cleaning hot water discharge pipe line. A flow path switching unit that can block the flow of hot water to the pipeline is not provided, and an opening / closing valve that can block the flow of water is not provided downstream of the branch portion with the hot water discharge pipeline in the cleaning hot water pipeline. An open / close valve that can block water flow is installed in the hot water discharge pipe line as the flow path switching unit. It was those.

このものでは、浴槽洗浄装置にて、熱源機で加熱生成された湯を洗浄液タンクの洗浄液と共に洗浄出湯管路を介して洗浄ノズルに供給する浴槽洗浄運転や、熱源機で加熱生成された湯を洗浄出湯管路から湯張り出湯管路を介して浴槽給湯口に供給する湯張り運転を行うことができるから、湯張り運転を実行する機能まで搭載されていない既設の給湯器を用いても、湯張り機能および浴槽洗浄機能を備えた風呂システムを構築できる。
しかも、このものでは、洗浄出湯管路における湯張り出湯管路との分岐部より下流側には開閉弁を設けないで、洗浄出湯管路から分岐する湯張り出湯管路に開閉弁を設け、上記開閉弁を開くことで、洗浄出湯管路に供給される湯が浴槽給湯口側へ導かれるように構成されているから、洗浄出湯管路に供給される湯を湯張り出湯管路へ導く流路切替部として、洗浄出湯管路と湯張り出湯管路との分岐部に三方分岐弁を設けるのに比べて、浴槽洗浄装置全体の構造を簡素化できる。
In this type, in the bathtub cleaning device, the hot water generated by the heat source machine is supplied to the cleaning nozzle together with the cleaning liquid in the cleaning solution tank to the cleaning nozzle via the cleaning hot water discharge pipe, and the hot water generated by the heat source machine is heated. Since it is possible to perform a hot water filling operation that supplies water from the washing hot water supply pipe to the bathtub hot water supply port via the hot water discharge hot water pipe, even using an existing water heater that is not equipped with a function for executing the hot water filling operation, It is possible to build a bath system with a water filling function and a bathtub cleaning function.
Moreover, in this one, an opening / closing valve is not provided at the downstream side of the branch portion with the hot water discharge pipe line in the washing hot water discharge pipe line, but an open / close valve is provided at the hot water discharge pipe line branched from the cleaning hot water discharge pipe line, By opening the on-off valve, the hot water supplied to the washing hot water outlet conduit is configured to be guided to the bathtub hot water supply port side, so the hot water supplied to the wash hot water outlet conduit is guided to the hot water outlet hot water outlet conduit. The structure of the entire bath cleaning device can be simplified as compared with a case where a three-way branch valve is provided as a flow path switching unit at the branch between the wash hot water discharge pipe and the hot water discharge hot water discharge pipe line.

好ましくは、上記浴槽洗浄装置において、給水配管から洗浄出湯管路へ水を導く温調給水管路と、給水配管から洗浄出湯管路に供給される水量を調整可能な水量調整部と、洗浄出湯管路に供給される湯と水との混合割合を湯量調整部および水量調整部によって調整する温調制御手段とを備える。   Preferably, in the bathtub cleaning device, a temperature control water supply conduit for guiding water from the water supply pipe to the cleaning hot water supply pipe, a water amount adjusting unit capable of adjusting the amount of water supplied from the water supply pipe to the cleaning hot water supply pipe, and the cleaning hot water. A hot water amount adjusting unit and a temperature adjusting control unit that adjusts a mixing ratio of hot water and water supplied to the pipeline by the hot water amount adjusting unit and the water amount adjusting unit.

このものでは、熱源機から供給される湯と、給水配管から供給される水との混合割合を調整して浴槽給湯口や洗浄ノズルに供給することができるから、出湯温を自在に変更できない簡素な構成の給湯器やソーラ温水器などの熱源機を用いても、湯張り機能および浴槽洗浄機能を備えた風呂システムを構築できる。   With this, the hot water supplied from the heat source unit and the water supplied from the water supply pipe can be adjusted to supply to the bathtub hot water supply port and the cleaning nozzle, so the hot water temperature cannot be changed freely. Even if a heat source device such as a water heater or a solar water heater with a different configuration is used, a bath system having a water filling function and a bathtub cleaning function can be constructed.

以上のように、本発明によれば、既設の給湯器を用いて湯張り機能および浴槽洗浄機能を備えた風呂システムを構築可能な、汎用性の高い浴槽洗浄装置を提供することが可能である。   As described above, according to the present invention, it is possible to provide a highly versatile bathtub cleaning device capable of constructing a bath system having a water filling function and a bathtub cleaning function using an existing water heater. .

また、洗浄湯張り操作端末5は、浴槽洗浄装置3の運転状態や設定された動作条件などを表示する表示部55と、湯張り運転や浴槽洗浄運転が終了したことを音声にて報知する音声出力部56とを備えている。   In addition, the water filling operation terminal 5 displays a display unit 55 that displays the operating state of the bathtub cleaning device 3 and the set operating conditions, and a voice that notifies the operator that the water filling operation and the bathtub washing operation have ended. And an output unit 56.

上記風呂システムの湯張り運転および浴槽洗浄運転時の制御動作を、図2のフローチャートに従って説明する。尚、以下の湯張り運転および浴槽洗浄運転を行うにあたって、給湯操作端末7にて運転指示操作が行われると、給湯器2が給湯待機状態となる。一方、洗浄湯張り操作端末5の運転スイッチ50のオン操作がなされ、浴槽洗浄装置3の運転が指示されると、洗浄湯張り制御回路3Cの主制御プログラムが起動し、湯張り運転や浴槽洗浄運転が実行可能な状態となる。   The control operation of the bath system during the filling operation and the bath washing operation will be described with reference to the flowchart of FIG. When the operation instruction operation is performed on the hot water supply operation terminal 7 in the following hot water filling operation and bath cleaning operation, the water heater 2 enters the hot water supply standby state. On the other hand, when the operation switch 50 of the flush water filling operation terminal 5 is turned on and the operation of the bath cleaning device 3 is instructed, the main control program of the flush water filling control circuit 3C is activated to perform the water filling operation or bath washing. The operation can be executed.

運転スイッチ50のオン操作がなされた後、浴槽洗浄スイッチ52のオン操作がなされず、湯張りスイッチ51のオン操作がなされた場合は(ST2のステップでYes)、自動排水栓13を閉じると共に、洗浄湯張り切替弁43を「湯張り側」に切り替えて、湯量調整弁47を湯張り時の設定開度に調整し、さらに出湯開閉弁45を開く。これにより、給湯配管L2から湯張り配管L5へ繋がる湯張り用の出湯経路が開通される(ST1〜ST4)。   When the bath switch cleaning switch 52 is not turned on after the operation switch 50 is turned on and the water filling switch 51 is turned on (Yes in step ST2), the automatic drain plug 13 is closed and The cleaning hot water filling switching valve 43 is switched to the “hot water filling side”, the hot water amount adjusting valve 47 is adjusted to the set opening for hot water filling, and the hot water outlet opening / closing valve 45 is opened. As a result, the hot water outlet path for hot water filling, which is connected from the hot water supply pipe L2 to the hot water filling pipe L5, is opened (ST1 to ST4).

上記湯張り用の出湯経路が開通されると、給水配管L1から給湯器2の熱交換器22への通水が開始される。そして、給湯器2にて水量センサの検出水量が所定量以上になれば、バーナ21が点火される。これにより、給湯器2から上記湯張り用の出湯経路を通じて浴槽金具11へ所定温度の湯が供給され、次第に浴槽1内に貯留されていく(ST5)。   When the hot water outlet path for hot water filling is opened, water flow from the water supply pipe L1 to the heat exchanger 22 of the water heater 2 is started. When the amount of water detected by the water amount sensor in the water heater 2 exceeds a predetermined amount, the burner 21 is ignited. As a result, hot water of a predetermined temperature is supplied from the water heater 2 to the bathtub fitting 11 through the hot water outlet path for filling the bath and is gradually stored in the bathtub 1 (ST5).

ST5のステップの湯張り運転が開始されてから、湯量センサ46の検知水量の積算値が洗浄湯張り操作端末5にて予め設定された湯張り量に達すれば(ST6のステップでYes)、湯張り運転が完了したことを表示部55に表示させると共に、音声出力部56から音声にて報知し、湯張り運転を終了する(ST6〜ST7)。   If the integrated value of the amount of water detected by the hot water amount sensor 46 reaches the preset water filling amount at the washing hot water filling operation terminal 5 after the start of the hot water filling operation in step ST5 (Yes in step ST6). The completion of the tensioning operation is displayed on the display unit 55, and the voice output unit 56 notifies by voice to end the hot water tensioning operation (ST6 to ST7).

一方、運転スイッチ50のオン操作がなされた後、浴槽洗浄スイッチ52のオン操作がなされた場合は(ST1のステップでYes)、自動排水栓13を開き、浴槽1内に溜まった湯を排出させる(ST8)。   On the other hand, when the bath cleaning switch 52 is turned on after the operation switch 50 is turned on (Yes in step ST1), the automatic drain plug 13 is opened to drain hot water accumulated in the bath 1. (ST8).

そして、自動排水栓13を開いてから予め設定された排水時間が経過すれば(ST9のステップでYes)、洗浄湯張り切替弁43を「洗浄側」に切り替えて、湯量調整弁47を洗浄時の設定開度に調整し、さらに出湯開閉弁45を開く。これにより、給湯配管L2から洗浄配管L6へ繋がる浴槽洗浄用の出湯経路が開通される(ST9〜ST10)。   When the preset drainage time elapses after opening the automatic drain plug 13 (Yes in step ST9), the cleaning hot water filling switching valve 43 is switched to the "cleaning side" to clean the hot water amount adjusting valve 47. Is adjusted to the set opening degree, and the hot water outlet opening / closing valve 45 is opened. As a result, the hot water supply path for bathtub cleaning, which is connected from the hot water supply pipe L2 to the cleaning pipe L6, is opened (ST9 to ST10).

尚、上記排水時間は、洗浄湯張り操作端末5により使用者が所定の範囲内(例えば、0分、5分、10分、20分)で任意に設定変更できる。このように、浴槽1内に残留した湯量に基づいて使用者が排水時間を設定することで、浴槽洗浄運転に要する時間を短縮できる。   The drainage time can be arbitrarily set and changed by the user using the washing water filling operation terminal 5 within a predetermined range (for example, 0 minutes, 5 minutes, 10 minutes, 20 minutes). In this way, the user sets the drainage time based on the amount of hot water remaining in the bathtub 1, whereby the time required for the bathtub washing operation can be shortened.

上記浴槽洗浄用の出湯経路が開通されると、給水配管L1から給湯器2の熱交換器22への通水が開始される。そして、給湯器2にて水量センサの検出水量が所定量以上になれば、バーナ21が点火される。これにより、給湯器2から上記浴槽洗浄用の出湯経路を通じて洗浄ノズル12へ所定温度の湯が供給され、浴槽1の内壁面へ向けて噴射される(ST11)。   When the hot water passage for washing the bathtub is opened, the water supply from the water supply pipe L1 to the heat exchanger 22 of the water heater 2 is started. When the amount of water detected by the water amount sensor in the water heater 2 exceeds a predetermined amount, the burner 21 is ignited. As a result, hot water of a predetermined temperature is supplied from the water heater 2 to the washing nozzle 12 through the hot water outlet path for bath washing, and is jetted toward the inner wall surface of the bath 1 (ST11).

本実施の形態では、ST11のステップの浴槽洗浄運転として、湯のみを所定時間噴射させる「予洗い工程」を行った後、洗浄液を湯に混合して所定時間噴射させる「洗浄工程」を所定回数(例えば、3回)行い、さらに湯のみを所定時間噴射させる「すすぎ工程」を行うように構成されている。また、上記洗浄工程を繰り返す回数、即ち、洗浄回数は、浴槽洗浄運転が開始される前に、洗浄湯張り操作端末5によって使用者が予め所定の範囲内(例えば、1〜5回)で任意に設定変更することができる。   In the present embodiment, as the bath washing operation in step ST11, after performing a "pre-washing step" in which hot water is sprayed for a predetermined time, a "washing step" in which a cleaning liquid is mixed with hot water and sprayed for a predetermined time is performed a predetermined number of times ( For example, it is performed three times, and a "rinsing step" in which only hot water is sprayed for a predetermined time is performed. In addition, the number of times the cleaning process is repeated, that is, the number of times of cleaning, can be arbitrarily set by the user within a predetermined range (for example, 1 to 5 times) by the cleaning water filling operation terminal 5 before the bath cleaning operation is started. You can change the setting.

そして、上記浴槽洗浄運転の全工程が終了すれば(ST12のステップでYes)、浴槽洗浄運転が完了したことを表示部55に表示させると共に、音声出力部56から音声にて報知する(ST12〜ST13)。   When all the steps of the bathtub washing operation are completed (Yes in step ST12), the completion of the bathtub washing operation is displayed on the display unit 55, and the voice output unit 56 gives a voice notification (ST12-). ST13).

また、浴槽洗浄運転が終了するまでの間に、湯張りスイッチ51のオン操作がなされている場合は(ST14のステップでYes)、浴槽洗浄運転が終了した後、引き続き上述したST3〜ST7のステップの湯張り運転を行う(ST14,ST3〜ST7)。   Further, when the hot water filling switch 51 is turned on by the time the bathtub cleaning operation is completed (Yes in step ST14), after the bathtub cleaning operation is completed, the steps ST3 to ST7 described above are continued. The hot water filling operation is performed (ST14, ST3 to ST7).

このように、上記風呂システムでは、給湯器2で加熱生成された湯を洗浄出湯管路31から湯張り出湯管路32を介して浴槽金具11に供給する湯張り運転と、給湯器2で加熱生成された湯を洗浄液と共に洗浄出湯管路31を介して洗浄ノズル12に供給する浴槽洗浄運転とを、浴槽洗浄装置3にて共に実行することができるから、上記給湯器2のように既設の給湯器が湯張り機能を備えていなくても、湯張り機能および浴槽洗浄機能を備えた風呂システムを構築できる。よって、汎用性が高い。   As described above, in the above bath system, the hot water generated by the hot water supply device 2 is supplied from the cleaning hot water supply pipe line 31 to the bathtub fitting 11 through the hot water supply pipe line 32, and the hot water supply device 2 heats the hot water. The bath cleaning operation of supplying the generated hot water together with the cleaning liquid to the cleaning nozzle 12 via the cleaning hot water outlet pipe 31 can be performed together in the bath cleaning device 3, and thus the existing hot water supply device like the water heater 2 can be used. Even if the water heater does not have a water filling function, a bath system having a water filling function and a bathtub cleaning function can be constructed. Therefore, versatility is high.

図3に示すように、浴槽洗浄装置3内に、給水配管L1から洗浄出湯管路31へ水を導く温調給水管路35が配設され、さらに温調給水管路35には、給水配管L1から洗浄出湯管路31に供給される水量を調整可能な水量調整部としての水量調整弁48が設けられ、洗浄出湯管路31に設けられた湯量調整弁47および上記水量調整弁48によって、湯張り配管L5或いは洗浄配管L6へ導出する湯と水との混合割合を調整可能な構成としたものであってもよい。   As shown in FIG. 3, a temperature control water supply conduit 35 that guides water from the water supply conduit L1 to the cleaning hot water supply conduit 31 is provided in the bathtub cleaning device 3, and the temperature control water supply conduit 35 further includes a water supply conduit. A water amount adjusting valve 48 as a water amount adjusting unit capable of adjusting the amount of water supplied from L1 to the wash hot water outlet pipe 31 is provided, and by the hot water amount adjusting valve 47 and the water amount adjusting valve 48 provided at the wash hot water outlet pipe 31 The configuration may be such that the mixing ratio of the hot water and the water led to the water filling pipe L5 or the cleaning pipe L6 can be adjusted.

詳述すると、温調給水管路35は、上流端が給水配管L1に接続され、下流端が洗浄出湯管路31の中間部における湯量センサ46の上流側で且つ湯量調整弁47の下流側の位置に合流接続されている。また、洗浄出湯管路31における湯量調整弁47の上流側には、給水配管L1から給湯配管L2へ水が逆流するのを防止するための逆流防止弁67が設けられ、温調給水管路35における水量調整弁48の上流側には、給湯配管L2から給水配管L1へ湯が逆流するのを防止するための逆流防止弁68が設けられている。   More specifically, the upstream end of the temperature control water supply pipe 35 is connected to the water supply pipe L1, and the downstream end of the temperature adjustment water supply pipe 35 is located upstream of the hot water amount sensor 46 and downstream of the hot water amount adjusting valve 47 in the middle portion of the washing hot water supply pipe 31. Confluently connected to the position. A backflow prevention valve 67 for preventing backflow of water from the water supply pipe L1 to the hot water supply pipe L2 is provided on the upstream side of the hot water amount adjusting valve 47 in the wash hot water supply pipe line 31, and the temperature control water supply pipe line 35 is provided. A backflow prevention valve 68 for preventing the backflow of hot water from the hot water supply pipe L2 to the water supply pipe L1 is provided on the upstream side of the water amount adjustment valve 48 in FIG.

このように、洗浄出湯管路31における湯量センサ46の上流側には、給湯配管L2からの湯の導入量を調整可能な湯量調整弁47と、給水配管L1からの水の導入量を調整可能な水量調整弁48とからなる湯水混合弁30が設けられており、上記湯水混合弁30の各弁開度を調整することで、湯張り配管L5或いは洗浄配管L6への出湯温が適宜変更される。   In this way, on the upstream side of the hot water amount sensor 46 in the washing hot water supply pipe 31, a hot water amount adjusting valve 47 capable of adjusting the amount of hot water introduced from the hot water supply pipe L2, and the amount of water introduced from the water supply pipe L1 can be adjusted. A hot and cold water mixing valve 30 including a water quantity adjusting valve 48 is provided, and the hot water temperature to the hot water filling pipe L5 or the cleaning pipe L6 is appropriately changed by adjusting the opening degree of each of the hot and cold water mixing valve 30. It

このものでは、給湯器2から供給される湯と、給水配管L1から供給される水との混合割合を調整することで、例えば、湯張り時の出湯温度を42℃、浴槽洗浄時の出湯温度を48℃に設定するなど、浴槽金具11から浴槽1内に供給される湯温(湯張り温度)や、洗浄ノズル12から浴槽1内に噴射させる湯温(洗浄温度)を適宜変更することができるから、出湯温の設定機能を備えていない給湯器やソーラ温水器などの熱源機を用いても、湯張り機能および浴槽洗浄機能を備えた風呂システムを構築でき、汎用性が一層高い。   In this case, by adjusting the mixing ratio of the hot water supplied from the water heater 2 and the water supplied from the water supply pipe L1, for example, the hot water temperature at the time of filling the water is 42 ° C., the hot water temperature at the time of washing the bathtub. The temperature of the hot water supplied from the metal fitting 11 into the bath 1 (filling temperature) and the temperature of the hot water sprayed from the cleaning nozzle 12 into the bath 1 (cleaning temperature) can be changed appropriately. Therefore, even if a heat source device such as a water heater or a solar water heater that does not have a function for setting the hot water temperature is used, a bath system having a water filling function and a bath washing function can be constructed, and the versatility is even higher.

上記各実施の形態では、洗浄出湯管路31と湯張り出湯管路32との合流部34に設けられた洗浄湯張り切替弁(三方分岐弁)43によって、給湯配管L2から洗浄出湯管路31に供給される湯を洗浄配管L6側と湯張り配管L5側とに切り替えて導出可能な構成としたものを説明したが、図4に示すように、洗浄湯張り切替弁43に代えて、湯張り出湯管路32における上記合流部34の下流側に、洗浄出湯管路31から湯張り出湯管路32への湯の流通を遮断可能な湯張り開閉弁49が配設され、上記湯張り開閉弁49を開くことによって、給湯配管L2から洗浄出湯管路31に供給される湯を湯張り配管L5側へ導出させ、閉じることによって、給湯配管L2から洗浄出湯管路31に供給される湯を洗浄配管L6側へ導出させる構成としたものであってもよい。   In each of the above-described embodiments, the cleaning hot water filling switching valve (three-way branch valve) 43 provided at the confluence portion 34 of the cleaning hot water discharging pipe line 31 and the hot water discharging hot water supplying pipe line 32 is used to clean the hot water discharging pipe line 31 from the hot water supply pipe L2. Although the hot water supplied to the cleaning pipe L6 side and the hot water filling pipe L5 side have been described as a derivable structure, as shown in FIG. A hot water filling opening / closing valve 49 capable of interrupting the flow of hot water from the washing hot water discharging pipe 31 to the hot water hot water discharging pipe 32 is provided on the downstream side of the confluence portion 34 in the hot water hot drawing pipe 32. By opening the valve 49, the hot water supplied from the hot water supply pipe L2 to the washing hot water discharge pipe line 31 is led to the hot water filling pipe L5 side, and closed to change the hot water supplied from the hot water supply pipe L2 to the washing hot water discharge pipe line 31. With a configuration that leads to the cleaning pipe L6 side Or it may be was.

このものでは、洗浄配管L6側と湯張り配管L5側との出湯流路の切り替えに、三方分岐弁よりも構造の簡素な開閉弁(湯張り開閉弁49)が用いられているから、浴槽洗浄装置3全体の構造を簡素化できる。   In this device, an on-off valve (water filling on-off valve 49) having a simpler structure than the three-way branch valve is used for switching the hot water flow passage between the cleaning pipe L6 side and the water filling pipe L5 side. The structure of the entire device 3 can be simplified.

尚、上記各実施の形態では、浴槽1に自動排水栓13が設けられ、浴槽洗浄運転が終了した後、引き続き湯張り運転が自動で実行されるように構成されたものを説明したが、本発明は、手動の排水栓が設けられた浴槽1を用いて風呂システムを構築してもよい。この場合、湯張り運転と浴槽洗浄運転とは連動せず、それぞれ独立して実行される。即ち、浴槽洗浄運転が終了した時点でその旨を報知し、その後、使用者が手動で排水栓を閉じ、湯張り運転の開始を手動で指示すれば、湯張り運転に移行するように構成される。 In addition, in each of the above-described embodiments, the automatic drain plug 13 is provided in the bathtub 1, and after the bathtub washing operation is finished, the filling operation is automatically performed. The invention may construct a bath system using the bathtub 1 provided with a manual drain plug.
