As shown in FIG. 3, the remote controller 72 includes an operation switch 102 that is turned on and off, a bath automatic button 104 that automatically fills the bathtub 18, a remedy button 106 that performs remedy, and a bathroom 22. And a call button 110 for calling an outside person. In addition, the remote controller 72 includes an additional water stop button 112 that stops additional water when the water supply device 26 adds additional water into the bathtub 18. These switches and a plurality of buttons constitute an operation unit 78 (see FIG. 2). Further, the remote controller 72 includes a display unit 76, a speaker 100, and a biological information sensor 94. Although not shown, the remote controller 72 may be provided with other buttons such as a setting button for setting the temperature of hot water in the bathtub 18.

  As shown in FIG. 1, in the water supply system 12, when the hot water filling pipe 62 is closed by the solenoid valve 32, the water supply section 30 passes through the water supply pipe 28, the hot water supply section 46, and the hot water filling pipe 62. Water is not supplied to the memorial return pipe 16B. Further, as shown in FIG. 5, in the water supply system 12, the water supply pipe 28, the hot water supply part 46, and the hot water supply pipe are supplied from the water supply unit 30 in a state where the hot water supply pipe 62 is opened by the opening operation of the electromagnetic valve 32. Water is supplied to the memorial return pipe 16 </ b> B through 62.

  In the present embodiment, the biological information sensor 94 functions as a bathing state detection unit that detects a predetermined bathing state in which a bather in the bathtub 18 may become abnormal. For example, the control unit 86 takes a bath when it is detected that there is no movement of the bather for a predetermined time or more based on the position information of the bather in the bathtub 18 detected by the human sensor as the biological information sensor 94. It is determined that the person has a predetermined bathing condition (heat stroke) that may become abnormal. Alternatively, the control unit 86 determines that the bather is abnormal when the heart rate of the bather detected by the heart rate sensor as the biological information sensor 94 is equal to or higher than a first threshold value as an example of a predetermined heart rate. It is determined as a predetermined bathing condition (heat stroke) that can be. Alternatively, the control unit 86 determines whether the bather is abnormal when the blood pressure of the bather detected by the blood pressure sensor as the biological information sensor 94 is equal to or higher than a second threshold value as an example of the predetermined blood pressure. The bathing state (heat stroke) is determined. Alternatively, the control unit 86 may perform a predetermined bathing state (hot) in which the bather may become abnormal when information that can be read from the electrocardiogram of the bather detected by the electrocardiogram sensor serving as the biological information sensor 94 satisfies a certain condition. Symptom). At this time, the control unit 86 opens the solenoid valve 32 and opens the hot water filling pipe 62. In this embodiment, when the absolute value of the bather's heart rate is equal to or greater than the first threshold value, the electromagnetic valve 32 is opened, but the change (increase) in the bather's heart rate is predetermined. The electromagnetic valve 32 may be opened when the heart rate becomes more than the change value (rise value). Similarly, in the present embodiment, when the absolute value of the bather's blood pressure becomes equal to or greater than the second threshold, the electromagnetic valve 32 is opened, but the change in the blood pressure of the bather (the increase) The electromagnetic valve 32 may be opened when a predetermined blood pressure change value (increased value) is reached.

  The controller 86 opens the electromagnetic valve 32 and then closes the electromagnetic valve 32 when a predetermined condition is satisfied. For example, when the temperature of the hot water detected by the hot water temperature sensor 64 becomes equal to or lower than a predetermined temperature (for example, a body temperature of about 36 ° C.) or when the additional water stop button 112 is pressed, Then, the solenoid valve 32 is closed, and the addition water is stopped.

  Next, the operation and effect of this embodiment will be described.

<Memorial operation>
In the state where hot water is stretched in the bathtub 18, the hot water piping 62 is closed by the electromagnetic valve 32. When the remedy button 106 of the remote controller 72 shown in FIG. 3 is pressed in a state where hot water is filled in the bathtub 18, the control unit 80 of the remote controller 72 shown in FIG. Thus, a memory command signal is output to the control unit 74. When the control unit 86 of the control unit 74 detects the chasing command signal, the chasing mode is set.

  As shown in FIG. 4, the control unit 86 (see FIG. 2) of the control unit 74 starts the chasing operation with the hot water filling pipe 62 closed by the electromagnetic valve 32. In the memory operation, the gas is supplied to the gas burner 54 and the ignition device is started to burn the gas in the gas burner 54. Further, the control unit 86 operates the circulation pump 42.

  When the circulation pump 42 is actuated, as shown by an arrow A, hot water in the bathtub 18 is sucked from the suction port 20B of the circulation port 20, and this sucked hot water is added to the heat source device 14 through the additional return pipe 16B. Returned to the heat exchanger 52 of the section 44. Further, the hot water returned to the heat exchanger 52 is heated by the gas burner 54, and the heated hot water is passed from the discharge port 20 </ b> A of the circulation port 20 to the bathtub 18 through the tracking forward passage pipe 16 </ b> A as indicated by an arrow A. It is discharged inside.

  A hot water temperature sensor 64 is provided in the remedy return pipe 16B, and the hot water temperature sensor 64 outputs a temperature detection signal corresponding to the temperature of the hot water flowing through the remedy return pipe 16B. During the chasing operation, the control unit 86 of the control unit 74 determines that the temperature detection value based on the temperature detection signal from the hot water temperature sensor 64 has reached a set value set as a predetermined chasing temperature. The above operation is repeated (until the temperature of the hot water reaches the set temperature). Thereby, the hot water in the bathtub 18 is tracked.

<When an abnormality is detected>
The control unit 86 enters the water supply mode when it is determined that an abnormality has been detected under a predetermined condition based on the biological information detected by the biological information sensor 94 (see FIG. 2 and the like). For example, when the controller 86 detects that there is no movement of the bather for a predetermined time or more based on the position information of the bather in the bathtub 18 detected by the human sensor as the biological information sensor 94, the biological information The bather detected by the blood pressure sensor as the biological information sensor 94 when the heart rate of the bather detected by the heart rate sensor as the sensor 94 is equal to or higher than the first threshold value as an example of the predetermined heart rate. The information that can be read from the electrocardiogram of the bather detected by the electrocardiogram sensor as the biological information sensor 94 satisfies a certain condition when the blood pressure of the blood pressure becomes equal to or higher than the second threshold value as an example of the predetermined blood pressure. It is determined that an abnormality has occurred (abnormality detection). When it is determined that an abnormality has occurred, the water supply mode is set, and as shown in FIG. 5, the controller 86 opens the hot water piping 62 by opening the solenoid valve 32. As a result, as shown by an arrow B, water flows from the water supply unit 30 through the water supply pipe 28 by the water supply pressure of the water supply, and further flows through the hot water supply unit 46 to the hot water supply pipe 62 to retreat. It is diverted by the pipe 16B. At this time, the gas burner 60 of the hot water supply unit 46 is not ignited. Then, as indicated by an arrow B, water flows in the opposite direction to the time of remedy through the remedy return pipe 16B, and water is supplied into the bathtub 18 from the suction port 20B of the circulation port 20. At the same time, as indicated by an arrow C, water flows from the follow-up return pipe 16B to the follow-up outgoing pipe 16A via the heat source unit 14, and water is supplied from the discharge port 20A of the circulation port 20 into the bathtub 18. . Thereby, additional water is performed at a temperature lower than the hot water in the bathtub 18. At this time, the chasing part 44 of the heat source machine 14 is stopped (the gas burner 54 of the chasing part 44 is not ignited).

  Here, control of the water supply system 12 of this embodiment is demonstrated more concretely.

  FIG. 6 is a flowchart of the control system of the water supply system 12 of the present embodiment. As shown in FIG. 6, in step 130, it is determined whether or not an abnormality has been detected. When the occurrence of an abnormality is detected in step 130, in step 132, the control unit 86 opens the solenoid valve 32 and opens the filling pipe 62. Thereby, additional water is started. On the other hand, if no occurrence of abnormality is detected in step 130, step 130 is repeated until the occurrence of abnormality is detected.

  Further, in step 134, the control unit 86 calculates an additional water amount (target value). More specifically, the control unit 86 predicts the current amount and temperature of the hot water in the bathtub 18 from the hot water filling data (for example, the bath set temperature, the water level of the hot water in the bathtub 18), and the predetermined temperature ( For example, the amount of added water (target value) that is equal to or less than the body temperature of about 36 ° C. is calculated.

For example, when the bath installation temperature is 40 ° C., the water level of the hot water in the bathtub 18 (the amount of hot water) is 200 L, and the temperature of the supplied water is 10 ° C., the additional water amount (target value) can be calculated by the following equation: .
(Additional water amount) = 200 × (40−36) / (36−10) ≈31L

  At this time, the temperature of the supplied water is detected by the feed water temperature sensor 68 when flowing through the water supply pipe 28. The temperature of the supplied water is also detected by the hot water temperature sensor 64 when it flows through the follow-up return pipe 16B. The temperature of the supplied water may be measured by either the feed water temperature sensor 68 or the hot water temperature sensor 64.

  Next, at step 136, it is determined whether or not water has been added to the target value. In the present embodiment, the amount of hot water is predicted from the hot water level in the bathtub 18 detected by the water level sensor 66, and it is determined whether or not the added water amount (target value) has been reached. When it is determined in step 136 that the water has been added to the target value, in step 138, the solenoid valve 32 is closed and the hot water piping 62 is closed. Thereby, the additional water is stopped. On the other hand, if it is not determined in step 136 that the water has been added to the target value, step 136 is repeated until the water has been added to the target value.

  Further, in step 140, the circulation pump 42 is operated (turned on). Thereby, hot water is circulated from the bathtub 18 to the memorial return pipe 16B and the memorial outgoing pipe 16A. Next, in step 142, it is determined whether the temperature of the hot water (bath temperature) detected by the hot water temperature sensor 64 is equal to or lower than a predetermined temperature (for example, body temperature of about 36 ° C.).

  If it is determined in step 142 that the temperature of the hot water detected by the hot water temperature sensor 64 (bath temperature) is equal to or lower than a predetermined temperature (for example, about 36 ° C., which is a body temperature), in step 144, an end determination criterion is set. It is determined whether or not the user is satisfied. As an end determination criterion, for example, when the safety of the bather is detected by the biological information sensor 94, or the bather is returned or discovered by the addition water stop button 112 (see FIG. 3) of the remote controller 72 being pressed. Cases. If it is determined in step 144 that the end determination criterion is satisfied, the operation of the circulation pump 42 is stopped (set to the OFF state) in step 146.

  On the other hand, if it is determined in step 142 that the hot water temperature (bath temperature) detected by the hot water temperature sensor 64 is not lower than a predetermined temperature (for example, body temperature of about 36 ° C.), the process returns to step 132 and the solenoid valve The hot water filling pipe 62 is opened by the opening operation 32, and the subsequent steps are repeated. If it is determined in step 144 that the end criterion is not satisfied, the process returns to step 142.

  In such a water supply system 12, the controller 86 activates the water supply device 26 when a predetermined bathing state is detected by the biological information sensor 94, thereby adding water at a temperature lower than the hot water in the bathtub 18. I do. Thereby, the temperature of the hot water in the bathtub 18 falls rather than before water supply. For this reason, in the water supply system 12, the control (soft) of the additional water by the water supply apparatus 26 is changed and the temperature of the hot water in the bathtub 18 is lowered without changing the hardware such that an automatic drain plug is retrofitted. The bather can be recovered from heat stroke early, or the heat stroke of the bather can be prevented in advance. In addition, since the water supply device 26 is connected to the circulation pipe 16 for remedy (in this embodiment, the remedy return pipe 16B), the circulation pipe 16 for remedy is used to make the water supply in the bathtub 18 more than hot water. Add water at a low temperature.

  Further, in the water supply device 26, the water supply pipe 28 is connected to the remedy return pipe 16 </ b> B via the hot water supply pipe 62 and the hot water supply unit 46, and the hot water supply pipe 62 includes an electromagnetic that opens and closes the hot water supply pipe 62. A valve 32 is provided. The controller 86 opens the hot water filling pipe 62 by opening the electromagnetic valve 32. Accordingly, water is supplied from the suction port 20B into the bathtub 18 through only the remedy return pipe 16B, and water is supplied from the discharge outlet 20A through the remedy forward pipe 16A to the bathtub 18 through the remedy return pipe 16B. Is supplied. For this reason, it is possible to add water to the bathtub 18 at a lower speed than the hot water in the bathtub 18 at a high speed.

  Furthermore, in the water supply system 12, the biological information sensor 94 includes a heart rate sensor that detects the heart rate of the bather in the bathtub 18, a human sensor that detects the position of the bather, a blood pressure sensor that detects the blood pressure of the bather, And at least one electrocardiogram sensor for detecting a bather's electrocardiogram. The control part 86 operates the water supply apparatus 26 based on the bathing state of the bather by the information detected by at least one of the heart rate sensor, the human sensor, the blood pressure sensor, and the electrocardiogram sensor. Thereby, for example, when the bather's heart rate and blood pressure are higher than the allowable values, or when the bather does not move, the water can be added at a temperature lower than the hot water in the bathtub 18.

  The water supply system 12 is provided with a remote controller 72 in which a speaker 100 that outputs sound is disposed in the bathroom 22, and the control unit 86 applies hot water in the bathtub 18 before operating the water supply device 26. You may make it alert | report to a bather from the speaker 100 that additional water is performed. This avoids suddenly adding water to the hot water in the bathtub 18 without notifying the bather in advance.

[Second Embodiment]
Next, the bathroom system 150 provided with the water supply system 152 of 2nd Embodiment of this invention is demonstrated using FIG. In addition, about the same component as 1st Embodiment mentioned above, the same number is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 7, the water supply system 152 includes a drainage actuator 154 as an opening / closing means that opens and closes a drainage plug (automatic drainage plug) 36 that closes the drainage port 34 at the bottom of the bathtub 18 in addition to the water supply device 26. ing. The control unit 86 (see FIG. 2) of the control unit 74 controls the operation of the drainage actuator 154. In the present embodiment, the drain plug 36 closes the drain port 34 by the drain actuator 154 when the bathtub 18 is filled with water. Further, when the water supply device 26 is operated to add water into the bathtub 18, the control unit 86 (see FIG. 2) opens the drain plug 36 by the drain actuator 154 and opens the drain port 34. Thereby, the hot water in the bathtub 18 is drained from the drain outlet 34, and the water supply device 26 adds water at a temperature lower than that of the hot water in the bathtub 18.

  In said water supply system 152, when adding water in the bathtub 18, it can suppress that the hot water in the bathtub 18 increases or overflows. Moreover, even when the bather loses consciousness or heat stroke, the bather can be prevented from drowning in the bathtub 18 in advance.

[Third Embodiment]
Next, the bathroom system 160 including the water supply system 162 according to the third embodiment of the present invention will be described with reference to FIGS. 8 and 9. In addition, about the same component as 1st and 2nd embodiment mentioned above, the same number is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 8, in the water supply system 162, the biological information sensor 94 mounted on the remote controller 72 of the water supply system 12 (see FIG. 2) of the first embodiment is not provided. In the water supply system 162, the control which operates the water supply apparatus 26 differs compared with the water supply system 12 of 1st Embodiment. In addition, the whole structure of the water supply system 162 of this embodiment is the same as the whole structure of the water supply system 12 of 1st Embodiment shown in FIG.

  FIG. 9 is a flowchart of the control system of the water supply system 162 of this embodiment. The water supply system 162 is different from the water supply system 12 of the first embodiment in that water is added from the water supply device 26 into the bathtub 18 to prevent a bathing accident before an abnormal state occurs.

  As shown in FIG. 9, in step 170, it is determined whether or not the bather's bathing is detected in the bathtub 18. The control unit 86 (see FIG. 8) detects that the bather has taken a bath in the bathtub 18 based on the information on the hot water level detected by the water level sensor 66. For example, when there is a rapid rise in the water level detected by the water level sensor 66, it is because a bather has entered the bathtub 18, and it is determined that bathing has been detected (the presence of the bather is present). When bathing is detected, the time from the start of bathing is measured by a timer 90 (see FIG. 8) as bathing time measuring means. If bathing is not detected in step 170, step 170 is repeated until bathing is detected.

  When bathing is detected in step 170, it is determined in step 172 whether or not bathing in hot water having a temperature equal to or higher than the threshold has been performed for a predetermined time. In general, it is said that soaking in hot water for a long time is the cause of heat shock (heat stroke). Is recommended as a safe bathing method "to rise to less than 10 minutes with hot water of 41 ℃ or less". In the present embodiment, in Step 172, it is determined whether or not bathing in hot water having a temperature equal to or higher than a threshold (for example, 40 ° C.) for a predetermined time (for example, 10 minutes). That is, in the present embodiment, the hot water temperature sensor 64 (see FIG. 8) and the timer 90 (see FIG. 8) that measures the bathing time of the bather in the bathtub 18 function as “bathing state detecting means”. Yes. If it is determined in step 172 that the bath has not been bathed in hot water having a temperature equal to or higher than a threshold (for example, 40 ° C.) for a predetermined time (for example, 10 minutes), the process returns to step 172.

  If it is determined in step 172 that the hot water having a temperature equal to or higher than the threshold (for example, 40 ° C.) has been taken for a predetermined time (for example, 10 minutes), in step 174, the speaker 100 (see FIG. 8) of the remote controller 72 is used. Outputs warning information. For example, the speaker 100 outputs information for calling attention such as “Please get out of the bath because there is a risk of a bathing accident”.

  Further, in step 176, it is determined whether or not the bather is absent in the bathtub 18. The control unit 86 (see FIG. 8) determines whether there is no bather in the bathtub 18 based on the information on the hot water level detected by the water level sensor 66. For example, when there is a rapid drop in the water level detected by the water level sensor 66, it is because the bather has left the bathtub 18 and it is determined that the bather is absent. If it is determined in step 176 that there is no bather, the control of the water supply system of this embodiment is terminated.

  On the other hand, if it is determined in step 176 that there is no bather, it is determined in step 178 whether or not a certain period of time has elapsed after calling attention. In the present embodiment, it is determined whether or not a certain time (for example, 3 minutes) has elapsed after alerting. If it is determined in step 178 that a certain period of time has not elapsed after alerting, the process returns to step 176.

  If it is determined in step 178 that a certain time has elapsed after alerting, in step 180, the speaker 100 of the remote controller 72 notifies the user that water will be added into the bathtub 18. In the present embodiment, information such as “a bathing accident may occur and water is added into the bathtub” is notified from the speaker 100.

  Next, in step 182, the electromagnetic valve 32 (see FIG. 8) is opened, and the water supply device 26 is operated. Thereby, addition water is performed in the bathtub 18.

  In the water supply system 162 of the present embodiment, when bathing in hot water having a temperature equal to or higher than a threshold value (for example, 40 ° C.) for a predetermined time (for example, 10 minutes), an alert is urged, and then for a certain time (for example, 3 minutes) When bathing, the water is forcibly added into the bathtub 18. For this reason, a bather can be in an abnormal state, that is, a bathing accident such as heat stroke can be prevented.

  Moreover, in the water supply system 162 of this embodiment, for example, when it is notified in step 180 that the hot water in the bathtub 18 is discharged from the speaker 100 of the remote controller 72, the bather manually controls the remote controller 72 (see FIG. 3). By pressing the add water stop button 112, the addition of water into the bathtub 18 may be stopped forcibly.

  In addition, in the water supply system 162 of this embodiment, although the biometric information sensor is not provided, it is good also as a structure which replaced with this structure and provided the biometric information sensor 94. That is, by providing the biological information sensor 94, as in the water supply system 12 of the first embodiment, water may be added into the bathtub 18 when an abnormal state of the bather is detected.

[Fourth Embodiment]
Next, the bathroom system 200 provided with the water supply system 202 of 4th Embodiment of this invention is demonstrated using FIG. In addition, about the same component as 1st-3rd embodiment mentioned above, the same number is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 10, in the water supply system 202, the heat source unit 14 is provided with a hot water supply unit 46, and a pipe 204 is connected to the hot water supply unit 46. The hot water supply unit 46 is configured to heat hot water supplied to the pipe 204 using the heat of the gas burner 60. A supply port 206 to which the pipe 204 is connected is provided in the bathtub 18. The supply port 206 is provided with a discharge port 206A, and hot water flowing through the pipe 204 is discharged into the bathtub 18 from the discharge port 206A. In addition, the water supply system 202 is provided with a water supply device 210 that is connected to the pipe 204 via the hot water supply unit 46 and serves as water supply means for adding water into the bathtub 18.

  The water supply apparatus 210 includes a water supply pipe 212 that supplies water to the secondary heat exchanger 58 of the hot water supply section 46, and a water supply section 214 that is arranged on the upstream side of the water flow direction of the water supply pipe 212. . The pipe 204 is provided with an electromagnetic valve 216 as a valve for opening and closing the pipe 204. The pipe 204 is provided with a hot water temperature sensor 64 for detecting the temperature of the hot water.

  Although not shown, the water supply pipe 212 for supplying water to the secondary heat exchanger 58 is configured to pass the water supplied from the water supply pipe 212 to the primary heat exchanger 56 after passing through the secondary heat exchanger 58. The pipe arranged in is connected. The pipe is connected to the upstream side of the pipe 204 in the hot water flow direction at the outlet of the primary heat exchanger 56. During normal hot water filling, water flowing from the secondary heat exchanger 58 to the primary heat exchanger 56 in the hot water supply unit 46 is heated using the heat of the gas burner 60, and hot water flows through the pipe 204. Yes. In the present embodiment, the gas burner 60 is not ignited when adding water from the water supply device 210 into the bathtub 18 through the pipe 204.

  Next, the operation of this embodiment will be described.

<During normal operation>
In the bathroom system 200 including the water supply system 202 described above, during normal hot water filling, the pipe 204 is opened by opening the electromagnetic valve 216, so that water flows from the water supply unit 214 through the water supply pipe 212. It is supplied to the hot water supply unit 46 of the heat source unit 14. In the hot water supply unit 46, the gas burner 60 is ignited to heat the water. Further, the heated hot water flows through the pipe 204 and is supplied into the bathtub 18 from the supply port 206. Then, with hot water stored in the bathtub 18, the piping 204 is closed by the closing operation of the electromagnetic valve 216. In addition, when it is desired to raise the temperature of the hot water in the bathtub 18 during bathing, hot hot water is supplied from the hot water supply unit 46 of the heat source device 14 through the pipe 204 and mixed with the hot water in the bathtub 18, so that the hot water in the bathtub 18 is mixed. Temperature rises.

<When an abnormality is detected>
In the water supply system 202, when an abnormal state is detected, the electromagnetic valve 216 is opened and the water supply device 210 is activated. Thus, water flows from the water supply unit 214 through the water supply pipe 212 and is supplied to the hot water supply unit 46, and further water is supplied from the supply port 206 in the bathtub 18 into the bathtub 18 through the pipe 204. At that time, since the gas burner 60 of the hot water supply section 46 is not ignited, the water is added into the bathtub 18 at a temperature lower than the hot water in the bathtub 18.

  In said water supply system 202, the temperature of the hot water in the bathtub 18 falls in the bathtub 18 by adding water at the temperature lower than the hot water in the bathtub 18 before water supply. For this reason, in the water supply system 202, by changing the control (soft) of the additional water by the water supply apparatus 210 and lowering the temperature of the hot water in the bathtub 18 without changing the hardware such that an automatic drain plug is retrofitted. The bather can be recovered from heat stroke early, or the heat stroke of the bather can be prevented in advance.

As shown in FIG. 11, the remote controller 72 of the bathroom 22 (see FIG. 1) is provided with a bathroom temperature sensor 234 as bathroom temperature detection means for detecting the temperature of the bathroom 22 (see FIG. 1). The bathroom temperature sensor 234 is electrically connected to the control unit 80. The temperature detection signal detected by the bathroom temperature sensor 234 is processed by the control unit 80 to measure the bathroom temperature. Information on the bathroom temperature is sent from the communication unit 82 of the remote controller 72 to the control unit 86 via the communication unit 88 of the control unit 74.

  A bathroom heater / dryer 236 is provided on the ceiling of the bathroom 22 (see FIG. 1). The control unit 86 is electrically connected to the bathroom heater / dryer 236 via the communication unit 88. The controller 86 controls the operation of the bathroom heater / dryer 236. The overall configuration of the bathroom system 230 is the same as that of the bathroom system 10 of the first embodiment except that a bathroom temperature sensor 234 and a bathroom heater / dryer 236 are provided.

  When the controller 86 detects that there is no movement of the bather for a predetermined time or more based on the position information of the bather in the bathtub 18 detected by the human sensor as the biological information sensor 94, the biological information sensor 94 is detected. When the heart rate of the bather detected by the heart rate sensor becomes equal to or higher than the first threshold value as an example of the predetermined heart rate, the bather's heart rate detected by the blood pressure sensor as the biological information sensor 94 When blood pressure becomes equal to or higher than a second threshold value as an example of predetermined blood pressure, or when information read from the electrocardiogram of a bather detected by an electrocardiogram sensor as the biological information sensor 94 satisfies a certain condition Then, the water supply device 26 is operated.

You may use the contact-type sensor detected by making it contact. Further, for example, a part of the human sensor, heart rate sensor, blood pressure sensor, and electrocardiogram sensor (for example, an electrocardiogram sensor) may be a contact-type sensor, and the other sensors may be non-contact sensors.

  Moreover, in the water supply system of 1st-5th embodiment, when the conditions of any one detection information of a human sensor, a heart rate sensor, a blood pressure sensor, and an electrocardiogram sensor are satisfy | filled, a water supply apparatus is operated and the bathtub 18 Although the water was added to the hot water inside, the present invention is not limited to this. For example, when a condition of detection information of any two or more of a human sensor, a heart rate sensor, a blood pressure sensor, and an electrocardiogram sensor is satisfied, the water supply device is operated to add water to the hot water in the bathtub 18. Also good.

  Moreover, in the water supply system of 1st-5th Embodiment, although the control part 86 determined with the predetermined bathing state (heat stroke) which may become abnormal based on the information detected by the biometric information sensor 94, this invention Is not limited to this configuration. For example, the control unit may determine a predetermined bathing state (heat stroke) that may be abnormal in response to some external signal.

  Moreover, in the water supply system of 1st-5th embodiment, it is not limited to the structure of each embodiment, It is good also as a structure which combined the structure of 1st-5th embodiment two or more. For example, in the bathroom system 200 of the fourth embodiment, the control provided with the bathroom heating dryer 236 of the bathroom system 230 of the fifth embodiment may be applied. Moreover, in the bathroom system 200 of 4th Embodiment, you may apply control which act | operates the drainage actuator 154 of 2nd Embodiment in the case of additional water.

  The embodiments of the present invention have been described with reference to the embodiments. However, these embodiments are merely examples, and various modifications can be made without departing from the scope of the invention. Further, it goes without saying that the scope of rights of the present invention is not limited to these embodiments and can be implemented in various modes without departing from the gist of the present invention.
