The hot water sent to the circulation circuit for remedy (42) is heated by the remedy burner (36) and then, as shown by the arrow in FIG. 53b), the second check valve (552) is opened and discharged from the hot water discharge port (10) of the case body (50 ) into the bathtub (20).
That is, during the reheating operation, the hot water in the bathtub (20) is moved from the hot water inlet (15) of the circulation fitting (5) to the hot water introduction chamber (57) to the first check by the operation of the bath pump (P). Valve (551) → Return pipe communication path (43a) → Return pipe (3a) → Recirculation circuit (42) → Forward pipe (3b) → Forward pipe communication path (53b) → Second check valve (552) → Circulate in order of hot water outlet (10).
この追い焚き運転動作時では、第4逆止弁(554)は、往き管連通路(53b)から流れ来る湯水によって第2窓部(512)を閉塞し、第3逆止弁(553)も閉じられたままである。よって、湯水が往き管連通路(53b)から第2窓部(512)を介して、ケース体(50)内の湯水導入室(57)に流れ込んで、湯水吸込口(15)からの吸水力を低下させたり、洗浄ノズル(17a)(17b)から浴槽(20)内の湯水が吸い込まれて、浴槽(20)内のゴミや垢等が洗浄ノズル(17a)(17b)内に付着したりすることがない。 During this reheating operation, the fourth check valve (554) closes the second window (512) with hot water flowing from the forward pipe communication path (53b), and the third check valve (553) Remains closed. Accordingly, hot water flows into the hot water introduction chamber (57) in the case body (50) from the forward pipe communication passage (53b) through the second window (512), and absorbs water from the hot water inlet (15). Or hot water in the bathtub (20) is sucked in from the cleaning nozzles (17a) and (17b), and dust and dirt in the bathtub (20) adhere to the cleaning nozzles (17a) and (17b). There is nothing to do.
浴室リモコン装置(103)にて湯張り運転が選択されると、給水回路(K)から通水される水は、給湯回路(30)にて、給湯バーナ(37)で加熱され、湯張り用給湯路(18)に送られる。その後、風呂用ポンプ(P)を介して往き管(3b)へ送られて、循環金具(5)のケース体(50)に設けられた湯水吐出口(10)から浴槽(20)内に吐出されて湯張りされる。
尚、湯張り運転時には風呂用ポンプ(P)は駆動させないことから、湯張り用給湯路(18)から風呂用ポンプ(P)を介して戻り管(3a)側にも流れようとするが、室外ユニット(1)内に設けられてある切替弁(39)によって、循環金具(5)へ到達しないように設定されている。
When hot water filling operation is selected in the bathroom remote control device (103), the water passed from the water supply circuit (K) is heated by the hot water supply burner (37) in the hot water supply circuit (30) and is used for hot water filling. It is sent to the hot water supply channel (18). After that, it is sent to the forward pipe (3b) via the bath pump (P) and discharged into the bathtub (20) from the hot water outlet (10) provided in the case body (50) of the circulation fitting (5). It is filled with hot water.
In addition, since the bath pump (P) is not driven during the hot water filling operation, it tends to flow from the hot water supply channel (18) to the return pipe (3a) side through the bath pump (P), The switching valve (39) provided in the outdoor unit (1) is set so as not to reach the circulation fitting (5).
次に、浴槽洗浄動作について説明する。
洗浄用リモコン装置(101)の洗浄運転スイッチ(104)が入力されると、洗剤補充検知部(28)の電極間に電流が流れ、洗剤の量が確認される。満タンの場合は、満タン表示が洗浄専用リモコン(101)の表示画面(105)に満タン表示が表示され、満タンでない場合は、満タン表示が解除されるから、必要に応じて、前記洗剤投入口(27)から洗剤タンク(22)内に洗剤を投入すれば良い。
Next, the bathtub cleaning operation will be described.
When the washing operation switch (104) of the washing remote control device (101) is input, a current flows between the electrodes of the detergent replenishment detection unit (28), and the amount of detergent is confirmed. If the tank is full, the full tank display is displayed on the display screen (105) of the washing remote control (101) .If the tank is not full, the full tank display is canceled. Detergent may be introduced into the detergent tank (22) from the detergent inlet (27).
次に、浴槽洗浄の順序とその内容を詳述する。
まず、浴槽(20)の排水のため、排水栓駆動部(48)が作動し、排水栓(44)が開弁される。浴槽(20)の排水が完了後、浴槽(20)の洗浄動作が開始する。
この洗浄動作では、予備すすぎ→洗剤洗浄→待機→仕上げすすぎが順次行なわれ、最後に、銀イオン洗浄が行なわれて洗浄動作が終了する。
予備すすぎ洗浄工程では、室外ユニット(1)の流量制御弁(14)が所定開度に設定されると共に、流路開閉弁(12)が開く。このとき、給水回路(K)からの通水を熱源機(3)が検出すると、これに内蔵された給湯バーナ(37)が燃焼して温水加熱動作が開始し、加熱された温水は湯水供給路(33)を通って、室外ユニット(1)に送り込まれる。
Next, the order and contents of bathtub cleaning will be described in detail.
First, for drainage of the bathtub (20), the drain plug driving section (48) is operated, and the drain plug (44) is opened. After the drainage of the bathtub (20) is completed, the washing operation of the bathtub (20) starts.
In this cleaning operation, preliminary rinsing → detergent cleaning → standby → finish rinsing is sequentially performed, and finally, silver ion cleaning is performed and the cleaning operation is completed.
In the preliminary rinsing process, the flow control valve (14) of the outdoor unit (1) is set to a predetermined opening, and the flow path opening / closing valve (12) is opened. At this time, when the heat source device (3) detects water flow from the water supply circuit (K), the hot water supply burner (37) built in it is combusted and the hot water heating operation is started, and the heated hot water is supplied with hot water. It is sent to the outdoor unit (1) through the path (33).
室外ユニット(1)内には、流量制御弁(14)により制御された一定水量の温水が流れ、室外ユニット(1)を通過した後は戻り管(3a)の一部(3a1)を通って、循環金具(5)の戻り管接続筒(54a)から、戻り管連通路(43a)へ流れ込む。戻り管連通路(43a)は第2仕切板(52)の第1部屋部(521)に連通していることから、図3に示すように、第1部屋部(521)内に流れ込んだ前記湯水の水圧によって、第3逆止弁(553)を開弁させて、第1部屋部(521)から第1仕切板(51)の包囲部(513)と第2仕切板(52)とで囲まれた範囲(この範囲は、第1、第2洗浄ノズル(17a)(17b)に連通している。)へ送られると共に、前方へ向って送られ、洗浄ノズル(17a)(17b)から、浴槽(20)の内壁面に噴射される。これにより、浴槽(20)の内壁面に付着している湯垢や毛髪等の汚れが予備的に洗い流される。
このとき、第1部屋部(521)内に流れ込んだ湯水の水圧によって、第1逆止弁(551)が第1窓部(511)を閉塞するから、湯水が第1窓部(511)から湯水導入室(57)に流れ込むことはない。よって、予備すすぎ洗浄用の湯水が湯水吐出口(10)から浴室(20)内に無駄に流れ出てしまうことはない。
予備すすぎ洗浄工程終了後、洗剤洗浄工程に移行する。
A constant amount of hot water controlled by the flow control valve (14) flows into the outdoor unit (1), and after passing through the outdoor unit (1), passes through a part (3a1) of the return pipe (3a). Then, it flows from the return pipe connecting tube (54a) of the circulation fitting (5) into the return pipe communication path (43a). Since the return pipe communication passage (43a) communicates with the first chamber portion (521) of the second partition plate (52), as shown in FIG. The third check valve (553) is opened by the water pressure of the hot water, so that the enclosure (513) of the first partition plate (51) and the second partition plate (52) from the first chamber portion (521). Sent to the enclosed range (this range communicates with the first and second washing nozzles 17a and 17b) and sent forward, from the washing nozzles 17a and 17b. And sprayed on the inner wall surface of the bathtub (20). As a result, dirt such as scale and hair adhering to the inner wall surface of the bathtub (20) is preliminarily washed away.
At this time, the first check valve (551) closes the first window (511) due to the water pressure of the hot water flowing into the first chamber (521), so that the hot water flows from the first window (511). It does not flow into the hot water introduction chamber (57). Therefore, the hot water for pre-rinsing and washing does not flow unnecessarily from the hot water outlet (10) into the bathroom (20).
After the preliminary rinsing cleaning process, the process proceeds to the detergent cleaning process.
洗剤洗浄工程では、上記予備すすぎの状態から、洗剤供給路(26)の洗剤開閉弁(23)が開かれると同時に、洗剤用回路(21)の上流端に設けられている切替弁(29)が洗剤用回路(21)側に切り替わる。これにより、洗剤用回路(21)に温水が流れ、この温水がベンチュリ構造の洗剤混合部(24)を通過する際に生じる負圧によって、洗剤タンク(22)からの洗剤が洗剤混合部(24)で温水と混合される。そして、温水と混合された洗浄液が洗剤用回路(21)の下流端から、戻り管(3a)に戻り、後は、前述した予備すすぎ工程の場合と同様に、戻り管(3a)→第2仕切板(52)の第1部屋部(521)→第3逆止弁(553)→洗浄ノズル(17a)(17b)へと送られ、洗浄ノズル(17a)(17b)から浴槽(20)の内壁面に向けて噴射される。これにより、前記内壁面に付着している前記汚れが洗浄される。
この洗浄液の噴射が所定時間実施されると、室内ユニット(2)の洗剤開閉弁(23)及び室外ユニット(1)の流路開閉弁(12)が閉じられて、洗浄ノズル(17a)(17b)からの洗浄液の噴射が停止され、洗剤洗浄工程が終了する。この洗剤洗浄工程が終了すると、待機工程に移行される。
In the detergent cleaning step, the switching valve (29) provided at the upstream end of the detergent circuit (21) at the same time that the detergent opening / closing valve (23) of the detergent supply path (26) is opened from the preliminary rinsing state. Switches to the detergent circuit (21) side. Thus, warm water flows into the detergent circuit (21), and the negative pressure generated when the warm water passes through the venturi-structured detergent mixing section (24) causes the detergent from the detergent tank (22) to flow into the detergent mixing section (24 ) And mixed with warm water. Then, the cleaning liquid mixed with the warm water returns to the return pipe (3a) from the downstream end of the detergent circuit (21), and thereafter, the return pipe (3a) → the second pipe as in the preliminary rinsing step described above. The first chamber portion (521) of the partition plate (52) → the third check valve (553) → the cleaning nozzle (17a) (17b) is sent to the bathtub (20) from the cleaning nozzle (17a) (17b). Injected toward the inner wall surface. Thereby, the dirt adhering to the inner wall surface is washed.
When the cleaning liquid is sprayed for a predetermined time, the detergent opening / closing valve (23) of the indoor unit (2) and the flow path opening / closing valve (12) of the outdoor unit (1) are closed, and the cleaning nozzles (17a) (17b) ) Is stopped, and the detergent cleaning process is completed. When this detergent cleaning process is completed, the process proceeds to a standby process.
待機工程では、洗浄ノズル(17a)(17b)からの一切の噴射を停止し、浴槽(20)の内壁面に洗浄液が付着した状態で、所定時間(本実施の形態では3分)が経過するまで待機する。この間に、洗浄液が浴槽(20)の内壁面に付着した湯垢等の汚れに浸透し、汚れを浮き上がられて次のすすぎ工程で洗い流し易くする。待機工程の終了後、仕上げすすぎ工程に移行する。
仕上げすすぎ工程では、基本的には上述した予備すすぎ洗浄工程と同様に、室外ユニット(1)の流路開閉弁(12)が開かれると共に、切替弁(29)が、予備すすぎ洗浄工程と同じ状態に切り替わり、熱源機(3)からの温水は、上記した通路を通って、洗浄ノズル(17a)(17b)から浴槽(20)の内壁面に向けて噴射される。これにより、浴槽(20)の内壁面にて洗浄液により浮き上がらせていた湯垢等の汚れが洗浄液と共に洗い流される。
この温水の噴射が所定時間(本実施の形態では2分)行なわれると、流路開閉弁(12)が閉じられ、洗浄ノズル(55)からの温水の噴射が停止し、仕上げすすぎ工程が終了される。
そして、上記工程が終了すると、銀イオン洗浄が実施される。
In the standby process, all injections from the cleaning nozzles (17a) and (17b) are stopped, and a predetermined time (3 minutes in the present embodiment) elapses with the cleaning liquid adhering to the inner wall surface of the bathtub (20). Wait until. During this time, the cleaning liquid permeates dirt such as scale adhering to the inner wall surface of the bathtub (20), and the dirt is lifted up to facilitate washing in the next rinsing step. After the end of the standby process, the process proceeds to the finish rinsing process.
In the final rinsing process, basically, the flow path opening / closing valve (12) of the outdoor unit (1) is opened and the switching valve (29) is the same as in the preliminary rinsing cleaning process, as in the preliminary rinsing cleaning process described above. The state is switched, and the hot water from the heat source machine (3) is jetted from the cleaning nozzles (17a) and (17b) toward the inner wall surface of the bathtub (20) through the passage. As a result, dirt such as scales floating on the inner wall surface of the bathtub (20) by the cleaning liquid is washed away together with the cleaning liquid.
When this hot water injection is performed for a predetermined time (2 minutes in the present embodiment), the flow path opening / closing valve (12) is closed, the hot water injection from the washing nozzle (55) is stopped, and the finish rinsing process is completed. Is done.
And when the said process is complete | finished, silver ion washing | cleaning is implemented.
銀イオン洗浄工程では、室外ユニット(1)の流量制御弁(14)が所定開度に設定されると共に流路開閉弁(12)が開かれ、且つ、銀イオン発生部(6)が稼動される。銀イオン洗浄工程では、給湯バーナ(37)を燃焼させず、加熱されない水が湯水供給路(33)から室外ユニット(1)に送り込まれ、流量制御弁(14)によって一定水量の水が室外ユニット(1)内を流れる。室外ユニット(1)を通過する際に、銀イオン発生部(6)にて発生させた銀イオンが水に混入される。そして、この銀イオンを含んだ銀イオン水は、戻り管(3a)の端部に達し、浴槽洗浄のための各工程と同様な通路を介して、洗浄ノズル(17a)(17b)から浴槽(20)内に噴射される。これにより、浴槽(20)の内壁面や風呂蓋、さらには、排水口や循環金具の内部も銀イオンでコーティングされることとなり、銀イオンの抗菌・除菌効果により、カビや雑菌の繁殖を抑えることができる。 In the silver ion cleaning process, the flow control valve (14) of the outdoor unit (1) is set to a predetermined opening, the flow path opening / closing valve (12) is opened, and the silver ion generation unit (6) is operated. The In the silver ion cleaning process, the hot water burner (37) is not burned and unheated water is sent from the hot water supply path (33) to the outdoor unit (1), and a constant amount of water is supplied to the outdoor unit by the flow control valve (14). (1) Flows through. When passing through the outdoor unit (1), the silver ions generated by the silver ion generator (6) are mixed into the water. Then, the silver ion water containing silver ions reaches the end of the return pipe (3a), and passes through the same passage as each step for washing the bathtub from the washing nozzles (17a) and (17b) to the bathtub ( 20) Injected in. As a result, the inner wall and bath lid of the bathtub (20), as well as the interior of the drain outlet and the circulation fittings, are also coated with silver ions. Can be suppressed.
この銀イオン水の噴射が所定時間(本実施の形態では2分)行なわれると、室外ユニット(1)の流路開閉弁(12)が閉じると共に、銀イオン発生部(6)の稼動が停止して、銀イオン洗浄工程が終了する。これで、浴槽洗浄の全工程が終了する。
尚、この実施の形態の洗浄ノズル(17a)(17b)は、すすぎ用の湯水又は洗浄液を、ケース体(50)の正面中央に設けた開口(50a)から前方斜め上方に向って噴出させる洗浄ノズル(17a)と、ケース体(50)の頂面に設けた開口(50b)から垂直方向に直噴出させる洗浄ノズル(17b)の二つのノズルを有する構成としてあるから、浴槽(20)の、循環金具(5)が設けられてある構成壁(200)には、洗浄ノズル(17a)からの噴出により、その浴槽内壁面(200a)にすすぎ用の湯水又は洗浄液を付着させることができ、他の浴槽内壁面には、洗浄ノズル(17a)からの噴出により湯水又は洗浄液を付着させることができる。
特に、構成壁(200)に、段部が設けられている構成の浴槽(20)の場合でも、段部の上方の浴槽内壁面(200a)にも洗浄ノズル(17a)から湯水又は洗浄液を噴出させて、洗浄やすすぎを実施することができる。このように、浴槽(20)の形状にかかわらず、浴槽内壁面全体にすすぎ用の湯水及び洗浄液をかけることができるので、浴槽の自動洗浄を確実に実施することができる。
When the injection of silver ion water is performed for a predetermined time (in this embodiment, 2 minutes), the flow path on / off valve (12) of the outdoor unit (1) is closed and the operation of the silver ion generator (6) is stopped. Then, the silver ion cleaning process is completed. This completes the entire bathtub cleaning process.
The cleaning nozzles (17a) and (17b) of this embodiment are used for cleaning hot water or cleaning liquid for rinsing from the opening (50a) provided in the front center of the case body (50) in a diagonally upward direction. Since the nozzle (17a) and the cleaning nozzle (17b) for direct ejection in the vertical direction from the opening (50b) provided on the top surface of the case body (50), the bathtub (20), Rinsing water or cleaning liquid can be attached to the inner wall surface (200a) of the bathtub by jetting from the cleaning nozzle (17a) to the component wall (200) provided with the circulation fitting (5). Hot water or cleaning liquid can be adhered to the inner wall surface of the bathtub by jetting from the cleaning nozzle (17a).
In particular, even in the case of a bathtub (20) configured to have a stepped portion on the component wall (200), hot water or cleaning liquid is also ejected from the cleaning nozzle (17a) to the inner wall surface (200a) of the bathtub above the stepped portion. Cleaning and rinsing can be performed. Thus, regardless of the shape of the bathtub (20), hot water and a rinsing liquid for rinsing can be applied to the entire inner wall surface of the bathtub, so that automatic washing of the bathtub can be performed reliably.
上記した第1番目の実施の形態は、洗剤用回路(21)に湯水を送り込む湯水供給路を熱源機(3)内の給湯回路(30)に接続させている。室外ユニット(1)には、逆流防止弁(13)が設けられてあるから、浴槽水や洗浄液や銀イオン混合液等が湯水供給路(33)を逆流して飲料用湯水に混入されるおそれはない。
図6に示すものは、第2番目の実施の形態の浴槽自動洗浄装置の概略構成図である。
このものは、湯水供給路(33)を、給湯回路(30)で加熱された温水を浴槽(20)へ送り込む湯張り用給湯路(18)としたものである。
In the first embodiment described above, the hot water supply path for supplying hot water to the detergent circuit (21) is connected to the hot water supply circuit (30) in the heat source machine (3). Since the outdoor unit (1) is provided with a backflow prevention valve (13), bath water, cleaning liquid, silver ion mixed liquid, etc., flow back through the hot water supply channel (33) and are mixed into the drinking hot water. It is not.
What is shown in FIG. 6 is a schematic block diagram of the bathtub automatic cleaning apparatus of 2nd Embodiment.
In this case, the hot water supply path (33) is a hot water supply path (18) for filling the hot water heated in the hot water supply circuit (30) into the bathtub (20).
室外ユニット(1)は、上述した第1番目の実施の形態と同様に、浴室外に設置されてあり、その内部には、湯水供給路(33)として機能する湯張り用給湯路(18)から追焚用循環回路(42)の戻り管(3a)を介して送り込まれる温水の流量を制御する流量制御弁(14)と銀イオン発生部(6)が収納されてあり、浴室内に設置させる室内ユニット(2)には、上記第1番目の実施の形態と同様に、洗剤タンク(22)に連通する洗剤用回路(21)と洗剤開閉弁(23)と洗剤混合部(24)と切替弁(29)が配設されている。 The outdoor unit (1) is installed outside the bathroom, as in the first embodiment described above, and has a hot water supply passage (18) that functions as a hot water supply passage (33). Contains a flow control valve (14) and a silver ion generator (6) that control the flow rate of hot water fed from the return circuit (3a) of the recirculation circuit (42) from inside, and is installed in the bathroom Similarly to the first embodiment, the indoor unit (2) to be operated includes a detergent circuit (21), a detergent opening / closing valve (23), and a detergent mixing section (24) communicating with the detergent tank (22). A switching valve (29) is provided.
この実施の形態のものでは、洗浄運転が実行されると、予備すすぎ洗浄を実施するために、湯張り用給湯路(18)に設けた弁装置(300)を開弁させ、給湯回路(30)に通水された水は給湯バーナ(37)で加熱され、温水となって、湯張り用給湯路(18)から、風呂用ポンプ(P)を介して追焚用循環回路(42)の戻り管(3a)に流入する。このとき、湯水は、往き管(3b)側にも流れ込むが、室外ユニット(1)内に設けた切替弁(49)を切り替えることにより、往き管(3b)は切替弁(49)で堰き止められる。 In this embodiment, when the cleaning operation is performed, the valve device (300) provided in the hot water supply water supply passage (18) is opened to perform preliminary rinsing, and the hot water supply circuit (30 ) Is heated by the hot water supply burner (37) to become hot water, and from the hot water supply water supply path (18) through the bath pump (P), the circulation circuit for the memorial circuit (42). It flows into the return pipe (3a). At this time, hot water flows into the forward pipe (3b), but by switching the switching valve (49) provided in the outdoor unit (1), the forward pipe (3b) is blocked by the switching valve (49). It is done.
戻り管(3a)に流入した湯水は室外ユニット(1)へ送られ、室外ユニット(1)内の切替弁(19)にて、銀イオン発生部(6)を配設した洗浄回路(38)を経由して、流量制御弁(14)で調節された流量の湯水が室内ユニット(2)へ送られ、室内ユニット(2)内の戻り管(3a)の一部(3a1)側を通過した後、上記第1番目の実施の形態と同じ構造の循環金具(5)に至り、洗浄ノズル(17a)(17b)から浴槽(20)の内壁面に向かって噴射される。 The hot water flowing into the return pipe (3a) is sent to the outdoor unit (1), and the switching valve (19) in the outdoor unit (1) is provided with a cleaning circuit (38) provided with a silver ion generating part (6). The hot water of the flow rate adjusted by the flow control valve (14) is sent to the indoor unit (2) via the and passes through a part (3a1) side of the return pipe (3a) in the indoor unit (2). Thereafter, the circulating metal fitting (5) having the same structure as that of the first embodiment is reached, and sprayed from the cleaning nozzles (17a) and (17b) toward the inner wall surface of the bathtub (20).
前記予備すすぎ洗浄工程にて浴槽(20)の内壁面の汚れを洗い流した後、次の洗剤洗浄工程に移行すると、室内ユニット(2)内の切替弁(29)が洗剤用回路(21)へ切り替わると同時に、洗剤開閉弁(23)が開弁する。これにより、給湯回路(30)から湯張り用給湯路(18)を介して、追焚用循環回路(42)の戻り管(3a)から室外ユニット(1)に流入した温水は、洗浄回路(38)の流量制御弁(14)にて所定流量に制御されると共に室内ユニット(2)の洗剤用回路(21)を通過する際に、洗剤タンク(22)内から送り出された洗剤が洗剤混合部(24)にて混合されることにより、洗浄液となって、循環金具(5)の洗浄ノズル(17a)(17b)から浴槽(20)の内壁面へ噴射される。 After washing away the dirt on the inner wall surface of the bathtub (20) in the preliminary rinsing washing process, when the process moves to the next detergent washing process, the switching valve (29) in the indoor unit (2) goes to the detergent circuit (21). At the same time of switching, the detergent opening / closing valve (23) opens. Thus, the hot water flowing into the outdoor unit (1) from the return pipe (3a) of the recirculation circuit (42) through the hot water supply passage (18) from the hot water supply circuit (30) is washed into the washing circuit ( The flow rate control valve (14) of 38) is controlled to a predetermined flow rate, and the detergent sent from the detergent tank (22) is mixed with the detergent when passing through the detergent circuit (21) of the indoor unit (2). By being mixed in the section (24), it becomes a cleaning liquid and is sprayed from the cleaning nozzles (17a) and (17b) of the circulation fitting (5) onto the inner wall surface of the bathtub (20).
その後の仕上げすすぎ工程では、基本的には上述した予備すすぎ洗浄工程と同様の流路を通って、温水のみが洗浄ノズル(17a)(17b)から浴槽(20)の内壁面に向けて噴射される。
上記した各実施の形態では、洗剤用回路(21)を、追焚循環回路(42)の戻り管(3a)に並列に接続させる構成としたから、浴槽自動洗浄装置用に別途配管を新設する必要がない。よって、浴槽自動洗浄装置の設置工事が容易となり、施工費用も安価に抑えることができる。特に、第2番目の実施の形態の場合では、湯水供給路(33)として従来の湯張り用給湯路(18)を利用しているから、湯水供給路(33)として別途配管を新設する必要がないから、戸外の施工もシンプルになる。
又、洗浄ノズル(17a)(17b)を、従来からの循環金具(5)内に設ける構成としたから、洗浄ノズル(17a)(17b)を浴槽(20)に穴を開けて取り付ける必要がなく、既設の浴槽(20)にも問題なく対応できると共に、漏水も問題もない。
In the subsequent finish rinsing process, basically, only warm water is jetted from the cleaning nozzles (17a), (17b) toward the inner wall surface of the bathtub (20) through the same flow path as the preliminary rinsing process described above. The
In each of the embodiments described above, the detergent circuit (21) is connected in parallel to the return pipe (3a) of the additional circulation circuit (42), so a separate pipe is newly installed for the bathtub automatic cleaning device. There is no need. Therefore, the installation work of the bathtub automatic cleaning device is facilitated, and the construction cost can be suppressed at a low cost. In particular, in the case of the second embodiment, since the conventional hot water supply channel (18) for hot water filling is used as the hot water supply channel (33), it is necessary to newly install a separate pipe as the hot water supply channel (33). Because there is no, the construction outside is also simplified.
