【発明の属する技術分野】
本発明は、浴槽への高温水供給を有したふろ給湯器に関するものである。
【0002】
【従来の技術】
従来の風呂給湯器は、リモコンの高温差し湯スイッチの操作により浴槽への高温水供給が行われるように構成されている。また、子供などの誤操作による火傷を防止するため、高温差し湯スイッチは数秒間連続で押された場合に、高温水の供給を可能とするように構成されている(例えば、特許文献1参照。)。
また、従来の浴槽用出湯器具(浴槽アダプタ)には、火傷に関する安全性を高めるために、吐出口に対向させて形状記憶合金バネを配置し、このバネにより開閉弁を開閉駆動するように構成して、湯張り時には開き、高温差し湯時には浴槽の水が空の状態だと前記形状記憶合金バネに高温水が触れて閉じ、浴槽への高温水供給を遮断する機能を持たせたものがある(例えば、特許文献2参照。)。

【発明が解決しようとする課題】
特許文献1に示された従来の風呂給湯器で、特許文献2に示された高温水遮断機能付きの浴槽アダプタを使用したとき、浴槽の水が空の状態では、本来、リモコンの湯張りスイッチを押して、湯張りを行うべきところ、浴槽内に水があるものと勘違いして、誤って、高温差し湯スイッチを押してしまうと、浴槽が空の状態から高温水供給が行われ、浴槽アダプタが遮断して高温差し湯は停止される。しかし、特許文献2に示すような高温水遮断機能付き浴槽アダプタがスイッチの誤操作や勘違い操作によって遮断されたという情報をユーザーはまったく知ることができなかったため、入浴しようとしたときにはじめて、浴槽にお湯が入っていないことに気付くことになり、使い勝手が悪いという課題があった。
【0005】
本発明は、上記のような課題を解消するためになされたもので、高温水遮断機能付き浴槽アダプタを通して高温差し湯を行うふろ給湯器において、使い勝手を向上することを目的とする。
【0006】
【課題を解決するための手段】
本発明に係るふろ給湯器は、リモコンのふろ湯張りスイッチの操作により浴槽への湯張りと該リモコンの高温差し湯スイッチの操作により浴槽への高温水の供給が高温水遮断機能付き浴槽アダプタを通して行われるふろ給湯器において、
ふろ給湯配管に流量検出手段を設け、浴槽への高温水の供給中に、前記流量検出手段により浴槽への毎秒当たりの供給流量が一定値以下を検出したときに、前記リモコンに前記高温水遮断機能付き浴槽アダプタの遮断動作を示すユーザーメッセージを表示し、前記高温水遮断機能付き浴槽アダプタの遮断動作を示すユーザーメッセージの表示中に、リモコンのふろ湯張りスイッチを操作して浴槽への湯張りを行った場合、前記ユーザーメッセージ表示を消灯して浴槽への湯張りを開始するとともに、この浴槽への湯張り中に、前記流量検出手段により浴槽への毎秒当たりの供給流量が一定値以下を検出したときは、再び、前記リモコンに前記高温水遮断機能付き浴槽アダプタの遮断動作を示すユーザーメッセージを表示するようにしたものである。

【0010】
高温差し湯設定湯温が80℃、高温差し湯設定湯量が20Lのときの高温差し湯動作、及び湯張り設定湯温が42℃、湯張り設定湯量が200Lのときの湯張り動作について、図2及び図3のフローチャートを用いて説明する。
【0011】
図2において、高温差し湯スイッチ22aが3秒連続で押されたかを判定し(S1)、押されたときは、リモコン22の高温水遮断機能付き浴槽アダプタ9が遮断したことを表すメッセージ表示部27aのユーザーメッセージ「U1」を消灯する(S2)。
次に、電動湯水混合弁6を高温差し湯設定温度の80℃になるように制御し(S3)、電磁弁11を開き(S4)、浴槽8への給湯を開始する。
ここで、浴槽8への給湯は、通常の状態では毎分10L以上がふろ給湯配管12内を流れている。
浴槽8に正常に給湯されている場合は、毎分2L(=33mL/秒)以上は余裕で流れているため、流量センサ10により瞬間流量33mL/秒以下を10秒連続で検出するかどうか監視し(S5)、流量センサ10が瞬間流量33mL/秒以上を検出しているときは、高温差し湯湯量が設定湯量の20Lになるまで高温差し湯を継続し(S6)、20Lになった時点で、電磁弁11を閉じて(S7)、高温差し湯は完了してS1に戻る。
【0012】
万一、誤って、浴槽8が空の状態から高温差し湯が行われたときは、高温水遮断機能付き浴槽アダプタ9が遮断され、瞬間流量が33mL/秒以下となる。このときは、流量センサ10が瞬間流量33mL/秒以下を10秒連続で検出して(S5)、制御部21は電磁弁11を閉じ(S8)、リモコン22のメッセージ表示部27aに高温水遮断機能付き浴槽アダプタ9が遮断動作したことを表すユーザーメッセージ「U1」を点滅表示させて(S9)、S2に戻る。
【0013】
一方、S1で、高温差し湯スイッチ24aが連続3秒以上押されていないときは、湯張りスイッチ23aが押されたかを判定し(S10)、湯張りスイッチ23aが押されたときは、リモコン22の高温水遮断機能付き浴槽アダプタ9が遮断動作したことを表すメッセージ表示部27aのユーザーメッセージ「U1」を消灯する(S11)。
次に、電動湯水混合弁6をふろ湯張り設定湯温の42℃になるように制御し(S12)、電磁弁11を開き(S13)、浴槽8への給湯を開始する。
ここで、浴槽8への給湯は、高温差し湯の場合と同様に通常の状態では毎分10L以上がふろ給湯配管12内を流れている。
従って、浴槽8に正常に給湯されている場合は、毎分2L(=33mL/秒)以上は余裕で流れているため、流量センサ10により瞬間流量33mL/秒以下を10秒連続で検出するかどうか監視し(S14)、流量センサ10が瞬間流量33mL/秒以上を検出しているときは、湯張り湯量が設定湯量の200Lになるまで、ふろ湯張りを継続し(S15)、200Lになった時点で、電磁弁11を閉じて(S16)、ふろ湯張りは完了し、図2のS1に戻る。
【0014】
S14で、流量センサ10が瞬間流量33mL/秒以下を10秒連続で検出したときは、電磁弁11を閉じる(S17)。
次に、S18で、リモコン22のメッセージ表示部27aにユーザーメッセージ「U1」表示をしてから30分以上かどうかを判断し、ユーザーメッセージ「U1」表示をしてから30分未満であれば、再び、リモコン22のメーッセージ表示部27aに高温水遮断機能付き浴槽アダプタ9が遮断動作したことを表すユーザーメッセージ「U1」を点滅表示させて(S19)、S1に戻る。
これは、浴槽8が空の状態から、高温差し湯を行われ、高温水遮断機能付き浴槽アダプタ9が遮断動作し、リモコン22のメッセージ表示部27aに「U1」表示されている状態では、ふろ給湯配管12内に高温のお湯が満たされており、20分〜30分経過しないと、ふろ給湯配管12内のお湯の温度が冷めないため、ふろ湯張りをしたときでも、ふろ給湯配管12内の高温のお湯が高温水遮断機能付き浴槽アダプタ9に導かれるため、再び、遮断動作するためである。この状態で、高温水遮断機能付き浴槽アダプタ9が遮断したことを表すユーザーメッセージ「U1」をリモコン22のメッセージ表示部27aに表示させるようにしている。
【0015】
リモコン22のメッセージ表示部27aにユーザーメッセージ「U1」表示をしてから30分以上が経過しても、流量センサ10が瞬間流量33mL/秒以下を検出しているときは、電磁弁11が固着して開かない、または、ふろ給湯配管12内に異物がつまって給湯ができないなどの別の理由で毎秒当たりの瞬間流量が33mL以下となっているので、ユーザーメッセージ「U1」表示から異常を表すエラーメッセージ「E1」の点滅表示に変更して(S20)、S1に戻る。
【0016】
このように、実施の形態1に示す構成によれば、リモコン22の高温差し湯スイッチ27aの操作により浴槽8への高温水の供給が高温水遮断機能付き浴槽アダプタ9を通して行われるとき、浴槽8への高温水の供給中に、流量センサ10により浴槽8への毎秒当たりの供給流量が33mL以下を検出したときに、前記リモコン22に前記高温水遮断機能付き浴槽アダプタ9の遮断動作を示すメッセージ「U1」表示を行うようにしたので、ユーザーに高温水遮断機能付き浴槽アダプタ9が遮断動作したことを知らせることができ、使い勝手が向上する。
【0017】
また、一旦、誤って、高温差し湯で浴槽アダプタ9が遮断動作したあとに、ふろ湯張り等、高温差し湯以外のふろ給湯で再び遮断動作したときも、知らせることができ、使い勝手が向上する。
【0018】
さらに、電磁弁11の故障やふろ給湯配管12内に異物がつまって給湯ができないことを表すエラーメッセージ表示と、誤操作や勘違いによる高温水遮断機能付き浴槽アダプタ9が遮断動作したことを表すユーザーメッセージ表示を分けて表示するようにしているため、使い勝手がさらに向上する。
なお、実施の形態1では、ヒーター式の電気温水器の例を示したが、ヒートポンプ式給湯器やガス給湯器などでも同様である。
【0019】
【発明の効果】
以上のように、本発明に係るふろ給湯器は、リモコンのふろ湯張りスイッチの操作により浴槽への湯張りと該リモコンの高温差し湯スイッチの操作により浴槽への高温水の供給が高温水遮断機能付き浴槽アダプタを通して行われるふろ給湯器において、ふろ給湯配管に流量検出手段を設け、浴槽への高温水の供給中に、前記流量検出手段により浴槽への毎秒当たりの供給流量が一定値以下を検出したときに、前記リモコンに前記高温水遮断機能付き浴槽アダプタの遮断動作を示すユーザーメッセージを表示し、前記高温水遮断機能付き浴槽アダプタの遮断動作を示すユーザーメッセージの表示中に、リモコンのふろ湯張りスイッチを操作して浴槽への湯張りを行った場合、前記ユーザーメッセージ表示を消灯して浴槽への湯張りを開始するとともに、この浴槽への湯張り中に、前記流量検出手段により浴槽への毎秒当たりの供給流量が一定値以下を検出したときは、再び、前記リモコンに前記高温水遮断機能付き浴槽アダプタの遮断動作を示すユーザーメッセージを表示するようにしたので、ユーザーに高温水遮断機能付き浴槽アダプタが遮断動作したことを知らせることができ、また、一旦、高温差し湯で浴槽アダプタが遮断動作したあとに、ふろ湯張り等、高温差し湯以外のふろ給湯で再び遮断動作したときも、ユーザーにメッセージで知らせることができ、使い勝手が向上する。
【0021】
さらに、電磁弁の故障やふろ給湯配管内に異物がつまって給湯ができないことを表すエラーメッセージと、誤操作や勘違いによる高温水遮断機能付き浴槽アダプタが遮断動作したことを表すユーザーメッセージを区別してリモコンに表示するため、使い勝手がさらに向上する。

It is a block diagram of the remote control which shows Embodiment 1 of this invention.
[0008]
In FIG. 1, 1 is a water supply pipe, 2 is a hot water storage tank for storing water or hot water, 3 is a heating element for boiling water in the hot water storage tank 2, and 4 is for controlling the boiling of water in the hot water storage tank 2. Boiling hot water temperature sensor for temperature input, 5 is a hot water supply pipe, 6 is an electric hot water mixing valve for mixing hot water and water and supplying hot water to the bathtub, 7 is an electric hot water mixing valve 6 Bath water temperature sensor for applying water, 8 is a bathtub, 9 is a bathtub adapter with a high-temperature water blocking function attached to the bathtub 8, 10 is a flow sensor for measuring the amount of hot water supplied to the bathtub 6, and 11 is a bathtub to the bathtub 8. An electromagnetic valve for opening and closing the hot water supply circuit 12, 12 is a hot water supply pipe connecting the electric hot / cold water mixing valve 6 to the bathtub adapter 9, 21 is a control unit for controlling the whole, 22 is a bathroom remote control, 22 a is in the bathroom remote control 21 It is a hot water hot water switch provided in.
[0009]
In FIG. 4, 22 is a bathroom remote control, 23a is a bath filling switch, 23b is a bath filling LED that lights during bath filling, 24a is a hot water hot water switch, and 24b is a hot bath LED that lights during hot bathing. 25a and 25b are hot water temperature setting switches, 26a and 26b are hot water temperature setting switches, 27a is a message display unit for displaying a user message, an error code, and the like, and 27b is a hot water setting hot water temperature and hot water hot water. A set hot water temperature display portion 27c for displaying the set hot water temperature, and 27c is a set hot water volume display portion for displaying the set hot water amount for hot water filling and the set hot water amount for high temperature hot water.
[0010]
The hot water hot water operation when the hot water hot water set hot water temperature is 80 ° C. and the hot water hot water set hot water amount is 20 L, and the hot water hot water operation when the hot water hot water set hot water temperature is 42 ° C. and the hot water hot water set hot water amount is 200 L 2 and the flowchart of FIG.
[0011]
In FIG. 2, it is determined whether or not the hot water hot water switch 22a has been pressed continuously for 3 seconds (S1). When the hot water hot water switch 22a is pressed, a message display section indicating that the bathtub adapter 9 with the hot water shut-off function of the remote controller 22 has been shut off. The user message “U1” of 27a is turned off (S2).
Next, the electric hot / cold water mixing valve 6 is controlled to reach the hot hot water set temperature of 80 ° C. (S3), the electromagnetic valve 11 is opened (S4), and hot water supply to the bathtub 8 is started.
Here, 10 L or more of the hot water supply to the bathtub 8 flows in the bath hot water supply pipe 12 in a normal state.
When the hot water is normally supplied to the bathtub 8, the flow rate is 2 L (= 33 mL / second) or more per minute, so it is monitored whether the instantaneous flow rate of 33 mL / second or less is continuously detected by the flow sensor 10 for 10 seconds. (S5) When the flow rate sensor 10 detects an instantaneous flow rate of 33 mL / second or more, the hot water supply is continued until the hot water supply amount reaches 20 L of the set hot water amount (S6), and the time reaches 20 L. Then, the solenoid valve 11 is closed (S7), the hot water supply is completed, and the process returns to S1.
[0012]
In the unlikely event that the hot water supply is performed from the state where the bathtub 8 is empty, the bathtub adapter 9 with a high-temperature water blocking function is blocked, and the instantaneous flow rate becomes 33 mL / second or less. At this time, the flow rate sensor 10 detects an instantaneous flow rate of 33 mL / sec or less continuously for 10 seconds (S5), the control unit 21 closes the electromagnetic valve 11 (S8), and the message display unit 27a of the remote controller 22 is shut off at high temperature water. A user message “U1” indicating that the bathtub adapter with function 9 has been shut off is displayed blinking (S9), and the process returns to S2.
[0013]
On the other hand, if the hot water hot water switch 24a has not been pressed for 3 seconds or more in S1, it is determined whether the hot water switch 23a has been pressed (S10), and if the hot water switch 23a has been pressed, the remote control 22 The user message “U1” of the message display unit 27a indicating that the bathtub adapter 9 with a high-temperature water shut-off function is shut off is turned off (S11).
Next, the electric hot / cold water mixing valve 6 is controlled so as to reach a bath water filling set hot water temperature of 42 ° C. (S12), the electromagnetic valve 11 is opened (S13), and hot water supply to the bathtub 8 is started.
Here, the hot water supply to the bathtub 8 flows in the bath hot water supply pipe 12 at a rate of 10 L or more per minute in a normal state as in the case of the hot water supply.
Accordingly, when the hot water is normally supplied to the bathtub 8, since the flow rate is 2 L (= 33 mL / sec) or more per minute, the flow rate sensor 10 detects the instantaneous flow rate of 33 mL / sec or less continuously for 10 seconds. If the flow rate sensor 10 detects an instantaneous flow rate of 33 mL / second or more, the hot water filling is continued until the hot water filling amount reaches 200 L of the set hot water amount (S15), and becomes 200 L. At this point, the solenoid valve 11 is closed (S16), the bath filling is completed, and the process returns to S1 in FIG.
[0014]
When the flow rate sensor 10 detects an instantaneous flow rate of 33 mL / second or less for 10 seconds continuously in S14, the electromagnetic valve 11 is closed (S17).
Next, in S18, it is determined whether or not it is 30 minutes or more after the user message “U1” is displayed on the message display portion 27a of the remote controller 22, and if it is less than 30 minutes after the user message “U1” is displayed, Again, the user message “U1” indicating that the bathtub adapter 9 with the hot water shutoff function has been shut off is blinked on the message display section 27a of the remote controller 22 (S19), and the process returns to S1.
In the state where the hot water supply is performed from the state where the bathtub 8 is empty, the bathtub adapter 9 with a high temperature water blocking function is shut off, and “U1” is displayed on the message display portion 27a of the remote controller 22, Since hot water in the hot water supply pipe 12 is filled with hot water and the temperature of the hot water in the hot water supply pipe 12 does not cool unless 20 to 30 minutes have passed, the hot water supply pipe 12 is filled even when the hot water is filled. This is because the high-temperature hot water is guided to the bathtub adapter 9 with a high-temperature water shut-off function, and thus shuts off again. In this state, the user message “U1” indicating that the bathtub adapter 9 with the hot water shutoff function is shut off is displayed on the message display unit 27a of the remote controller 22.
[0015]
Even when 30 minutes or more have elapsed after displaying the user message “U1” on the message display portion 27a of the remote controller 22, the electromagnetic valve 11 is fixed when the flow sensor 10 detects an instantaneous flow rate of 33 mL / second or less. Because the instantaneous flow rate per second is 33 mL or less due to another reason such as the hot water supply pipe 12 is not open due to foreign matter clogging and hot water supply cannot be performed, an abnormality is indicated from the user message “U1” display. The display is changed to the blinking display of the error message “E1” (S20), and the process returns to S1.
[0016]
Thus, according to the configuration shown in the first embodiment, when the hot water supply to the bathtub 8 is performed through the bathtub adapter 9 with a high-temperature water shut-off function by the operation of the hot water hot water switch 27a of the remote controller 22, the bathtub 8 When the flow rate sensor 10 detects that the supply flow rate per second to the bathtub 8 is 33 mL or less during the supply of the high-temperature water to the remote controller 22, a message indicating the shut-off operation of the bathtub adapter 9 with the high-temperature water shut-off function to the remote controller 22 Since “U1” is displayed, the user can be notified that the bathtub adapter 9 with the high-temperature water shut-off function has been shut off, and the usability is improved.
[0017]
Moreover, once the bathtub adapter 9 has been shut off by high-temperature hot water and then shut off again by using a hot water supply other than hot water such as bathing hot water, it can be notified and the usability is improved. .
[0018]
In addition, an error message display indicating that the solenoid valve 11 has failed or that foreign substances are clogged in the hot water supply pipe 12 and that hot water cannot be supplied, and a user message indicating that the bathtub adapter 9 with a hot water shutoff function has been shut off due to an erroneous operation or misunderstanding. Since the display is divided and displayed, the usability is further improved.
In the first embodiment, an example of a heater-type electric water heater is shown, but the same applies to a heat pump water heater, a gas water heater, and the like.
[0019]
【The invention's effect】
As described above, the hot water heater according to the present invention is configured such that the hot water filling to the bathtub by the operation of the hot water filling switch of the remote control and the hot water supply to the bathtub by the operation of the hot water hot water switch of the remote control is blocked. In a bath water heater that is operated through a bathtub adapter with a function, a flow rate detecting means is provided in the bath hot water piping, and during the supply of high-temperature water to the bathtub, the flow rate per second to the bathtub is kept below a certain value by the flow rate detecting means.
