本発明によれば、浴槽内湯温に応じて浴槽に対する温泉水の供給と補給水の供給とを制御することにより浴槽内湯温を自動的に制御することができる。即ち、加熱手段を用いることなく、浴槽内湯温を一定の範囲内に制御することができる。   According to the present invention, the hot water temperature in the bathtub can be automatically controlled by controlling the supply of hot spring water to the bathtub and the supply of makeup water according to the hot water temperature in the bathtub. That is, the bath water temperature can be controlled within a certain range without using a heating means.

符号1に示すものは浴槽である。浴槽1に温泉を供給する温泉供給管路3と浴槽1に補給水を供給する補給水供給管路5とを設ける。図示の事例においては、温泉供給管路3と補給水供給管路5とが一本の共通供給管路7に合流し、該共通供給管路7が浴槽1に接続されている。   What is shown by the code | symbol 1 is a bathtub. A hot spring supply line 3 for supplying hot water to the bathtub 1 and a makeup water supply line 5 for supplying makeup water to the bathtub 1 are provided. In the illustrated example, the hot spring supply line 3 and the makeup water supply line 5 merge into one common supply line 7, and the common supply line 7 is connected to the bathtub 1.

温泉供給管路3にはPID制御の第一自動モーターバルブ9とON−OFF制御の第二自動モーターバルブ11とを並列状に配設する。   A first automatic motor valve 9 for PID control and a second automatic motor valve 11 for ON-OFF control are arranged in parallel in the hot spring supply line 3.

図示の事例においては、第一自動モーターバルブ9の上流と下流とにそれぞれ手動バルブ13、15が配設されている。   In the illustrated example, manual valves 13 and 15 are disposed upstream and downstream of the first automatic motor valve 9, respectively.

図示の事例においては、第二自動モーターバルブ11の上流と下流とにそれぞれ手動バルブ17、19が配設されている。   In the illustrated example, manual valves 17 and 19 are disposed upstream and downstream of the second automatic motor valve 11, respectively.

図示の事例においては、更にバイパスバルブ21が第一自動モーターバルブ9と第二自動モーターバルブ11とに対し並列状に配設されている。   In the illustrated example, a bypass valve 21 is further arranged in parallel with the first automatic motor valve 9 and the second automatic motor valve 11.

補給水供給管路5にはON−OFF制御の第三自動モーターバルブ23を配設する。   A third automatic motor valve 23 with ON-OFF control is disposed in the makeup water supply pipe 5.

図示の事例においては、第三自動モーターバルブ23の上流と下流とにそれぞれ手動バルブ25、27が配設されている。   In the illustrated example, manual valves 25 and 27 are disposed upstream and downstream of the third automatic motor valve 23, respectively.

図示の事例においては、更にバイパスバルブ29が第三自動モーターバルブ23に対し並列状に配設されている。   In the illustrated example, a bypass valve 29 is further arranged in parallel with the third automatic motor valve 23.

符号31に示すものは浴槽内湯温を検知する湯温センサーであり、符号33に示すものは浴槽内湯温の所望の設定値と該設定値よりも高い上限値と該設定値よりも低い下限値とを設定するための湯温設定手段である。   What is indicated by reference numeral 31 is a hot water temperature sensor for detecting the hot water temperature in the bathtub, and what is indicated by reference numeral 33 is a desired set value of the hot water temperature in the bathtub, an upper limit value higher than the set value, and a lower limit value lower than the set value. Is a hot water temperature setting means.

湯温設定手段33は、湯温センサー31が検知した浴槽内湯温の情報を第一自動モーターバルブ9と第二自動モーターバルブ11と第三自動モーターバルブ23とに伝え、これらのバルブ9、11、23に所定の動作を行なわせる。   The hot water temperature setting means 33 transmits information on the hot water temperature in the bathtub detected by the hot water temperature sensor 31 to the first automatic motor valve 9, the second automatic motor valve 11, and the third automatic motor valve 23, and these valves 9, 11 , 23 to perform a predetermined operation.

浴槽1の管理者等は、湯温設定手段33により所望の湯温を設定する。この設定値(図2における符号41参照。)は、一例として42℃とする。   The manager of the bathtub 1 sets a desired hot water temperature by the hot water temperature setting means 33. This set value (see reference numeral 41 in FIG. 2) is 42 ° C. as an example.

浴槽内湯温が設定値になるように第一自動モーターバルブ9に浴槽1に対する温泉の供給量を制御させる。   The first automatic motor valve 9 is caused to control the amount of hot spring supplied to the bathtub 1 so that the hot water temperature in the bathtub becomes a set value.

浴槽内湯温が設定値になるように第一自動モーターバルブ9に浴槽1に対する温泉の供給量を制御させている場合でも、浴槽内湯温は、外乱その他の原因により、設定値よりも高くなることがある。浴槽内湯温が設定値よりも高い上限値(図2における符号43参照。)まで上昇したとき(符号47)には第三自動モーターバルブ23に浴槽1に対し補給水を供給させ、該補給水の供給により浴槽内湯温が設定値まで降下回復したとき(符号49)には第三自動モーターバルブ23を閉じる。即ち、第三自動モーターバルブ23は、符号51に示す時間、浴槽1に補給水を供給する。   Even when the first automatic motor valve 9 controls the amount of hot spring supplied to the bathtub 1 so that the hot water temperature in the bathtub becomes the set value, the hot water temperature in the bathtub should be higher than the set value due to disturbance or other causes. There is. When the hot water temperature in the bathtub rises to an upper limit value (see reference numeral 43 in FIG. 2) higher than the set value (reference numeral 47), the third automatic motor valve 23 is supplied with makeup water to the bathtub 1, and the makeup water is supplied. When the hot water temperature in the bathtub drops and recovers to the set value due to the supply of (No. 49), the third automatic motor valve 23 is closed. That is, the third automatic motor valve 23 supplies makeup water to the bathtub 1 for the time indicated by reference numeral 51.

因みに、浴槽内湯温が設定値よりも高い上限値まで上昇したときには、第一自動モーターバルブ9は浴槽1に対する温泉の供給を停止する。即ち、浴槽内湯温の上昇が阻止され、安全性が確保される。   Incidentally, when the hot water temperature in the bathtub rises to an upper limit value higher than the set value, the first automatic motor valve 9 stops supplying hot springs to the bathtub 1. That is, the rise of the bath water temperature is prevented, and safety is ensured.

上限値は任意に設定することができる。上限値は、設定値よりも例えば0.2〜0.5℃高い温度とする。即ち、例えば、設定値が42℃のときは、上限値は42.2〜42.5℃である。   The upper limit value can be set arbitrarily. The upper limit value is, for example, 0.2 to 0.5 ° C. higher than the set value. That is, for example, when the set value is 42 ° C., the upper limit value is 42.2 to 42.5 ° C.

浴槽内湯温が設定値になるように第一自動モーターバルブ9に浴槽1に対する温泉の供給量を制御させている場合でも、浴槽内湯温は、外乱その他の原因により、設定値よりも低くなることがある。浴槽内湯温が設定値よりも低い下限値(図2における符号45参照。)まで降下したとき(符号53)には第二自動モーターバルブ11に浴槽1に対し温泉を供給させ、該温泉の供給により浴槽内湯温が設定値まで上昇回復したとき(符号55)には第二自動モーターバルブ11を閉じる。即ち、第二自動モーターバルブ11は、符号57に示す時間、浴槽1に温泉を供給する。   Even when the first automatic motor valve 9 controls the amount of hot spring supplied to the bathtub 1 so that the hot water temperature in the bathtub becomes the set value, the hot water temperature in the bathtub should be lower than the set value due to disturbance or other causes. There is. When the bath water temperature falls to a lower limit value lower than the set value (see reference numeral 45 in FIG. 2) (reference numeral 53), the second automatic motor valve 11 is supplied with hot springs to the bathtub 1, and the hot springs are supplied. Thus, when the hot water temperature in the bathtub rises and recovers to the set value (reference numeral 55), the second automatic motor valve 11 is closed. That is, the second automatic motor valve 11 supplies hot springs to the bathtub 1 for the time indicated by reference numeral 57.

下限値は、任意に設定することができる。下限値は、設定値よりも例えば0.2〜0.5℃低い温度とする。即ち、例えば、設定値が42℃のときは、下限値は41.5〜41.8℃である。   The lower limit value can be set arbitrarily. The lower limit value is, for example, 0.2 to 0.5 ° C. lower than the set value. That is, for example, when the set value is 42 ° C., the lower limit value is 41.5 to 41.8 ° C.

以上により、浴槽内湯温は常時上限値と下限値との間に維持される。   As described above, the bath water temperature is always maintained between the upper limit value and the lower limit value.

温泉を常時定量的に浴槽1内に注入したい場合には、第二自動モーターバルブ11による温泉の供給量を浴槽内湯温が設定値に達しない程度に手動バルブ17、19により調整した状態で、第二自動モーターバルブ11を手動操作により開いた状態に保持すると共に、PID制御の第一自動モーターバルブ9を作用させるようにしてもよい。しかるときは、浴槽内湯温が降下したときには、第一自動モーターバルブ9が自動的に開いて浴槽内湯温を保持する。この場合には、補給水は使用されない。   When it is desired to always infuse hot springs into the bathtub 1, the amount of hot spring supplied by the second automatic motor valve 11 is adjusted by the manual valves 17 and 19 so that the hot water temperature in the bathtub does not reach the set value. The second automatic motor valve 11 may be held in an open state by a manual operation, and the PID-controlled first automatic motor valve 9 may be operated. When the bath water temperature falls, the first automatic motor valve 9 automatically opens to maintain the bath water temperature. In this case, make-up water is not used.

また、補給水の使用が経済的に可能な場合には、第三自動モーターバルブ23の流量をその手動バルブ25、27により制御した状態で第三自動モーターバルブ23を手動操作により開いた状態に保持すると共に、PID制御の第一自動モーターバルブ9と第二自動モーターバルブ11とを作用させるようにしてもよい。この場合には、常時一定量の補給水が浴槽1内に供給されるのであるから、浴槽内湯温は降下しようとするのであるが、第一自動モーターバルブ9が自動的に温泉を浴槽1に供給することにより浴槽内湯温は設定値に保持される。なお、浴槽内湯温が下限値まで降下したときには、第二自動モーターバルブ11が自動的に温泉を浴槽1に供給し、浴槽内湯温が設定値に達したときには、第二自動モーターバルブ11は自動的に閉じる。   If the use of makeup water is economically possible, the third automatic motor valve 23 is opened by manual operation while the flow rate of the third automatic motor valve 23 is controlled by the manual valves 25 and 27. While holding, the PID-controlled first automatic motor valve 9 and the second automatic motor valve 11 may be operated. In this case, since a certain amount of makeup water is always supplied into the bathtub 1, the hot water temperature in the bathtub is about to drop, but the first automatic motor valve 9 automatically brings the hot spring into the bathtub 1. By supplying the hot water in the bathtub, the set temperature is maintained. When the bath water temperature falls to the lower limit value, the second automatic motor valve 11 automatically supplies hot springs to the bathtub 1, and when the bath water temperature reaches the set value, the second automatic motor valve 11 automatically Close.
