Further, the remote controller 72 includes a heat shock prevention mode button 114 for setting a prohibition mode for prohibiting the temperature of the hot water in the bathtub 18 from being set to a predetermined temperature (for example, 41 ° C.) or higher. The operation unit 78 (see FIG. 2) is composed of these switches and a plurality of buttons. 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.

In the bathroom system 10, the remote controller 72 is configured such that the temperature of the hot water in the bathtub 18 cannot be set to a predetermined temperature (for example, 41 ° C.) or higher while the heat shock prevention mode button 114 is pressed. That is, even if the control unit 80 of the remote controller 72 tries to set the temperature of the hot water in the bathtub 18 to a predetermined temperature (for example, 41 ° C.) or higher by pressing the setting button (not shown), for example, the signal of the setting button Will not be accepted. Further, in the bathroom system 10, when the temperature of the hot water detected by the hot water temperature sensor 64 is equal to or higher than a predetermined temperature (for example, 41 ° C.) while the heat shock prevention mode button 114 is pressed, the control unit 86 operates. , Even if the reheating button 106 of the remote controller 72 is pressed, the reheating mode is not executed. That is, the circulation pump 42 and the reheating unit 44 do not operate, and the hot water in the bathtub 18 is not reheated and circulated in the circulation pipe 16 (see FIG. 1).

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 unit 30 passes through the water supply pipe 28, the hot water supply unit 46, and the hot water filling pipe 62. Water is not supplied to the reheating return pipe 16B. Further, as shown in FIG. 5, in the water supply system 12, when the hot water filling pipe 62 is opened by the opening operation of the solenoid valve 32, the water supply pipe 28, the hot water supply unit 46, and the hot water filling pipe from the water supply unit 30 are opened. Water is supplied to the reheating return pipe 16B via 62.

In the bathroom system 10, when the temperature of the hot water detected by the hot water temperature sensor 64 is equal to or higher than a predetermined temperature (for example, 41 ° C.) while the heat shock prevention mode button 114 is pressed, the control unit 86 sets the bathtub. Control is performed so that the temperature of the hot water in 18 becomes lower than a predetermined temperature. For example, the control unit 86 controls the thermal power of the hot water supply unit 46 of the heat source machine 14 so that hot water water having a temperature lower than a predetermined temperature (for example, 41 ° C.) is stored in the bathtub 18 at the time of filling with hot water. Further, for example, after the hot water is stored in the bathtub 18, the control unit 86 operates the water supply device 26 to add water to the bathtub 18 at a temperature lower than that of the hot water in the bathtub 18.

In the present embodiment, the biological information sensor 94 functions as a bathing state detecting means for detecting a predetermined bathing state in which the 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 certain period of time or more based on the position information of the bather in the bathtub 18 detected by the motion sensor as the biological information sensor 94. It is determined that the person is in a predetermined bathing state that can be abnormal. Alternatively, when the heart rate of the bather detected by the heart rate sensor as the biological information sensor 94 becomes equal to or higher than the first threshold value as an example of the predetermined heart rate, the control unit 86 causes the bather to be abnormal. It is determined that the bathing condition is a predetermined bathing condition. Alternatively, the control unit 86 determines that the bather may become abnormal when the blood pressure of the bather detected by the blood pressure sensor as the biological information sensor 94 becomes equal to or higher than the second threshold value as an example of the predetermined blood pressure. It is judged that the bathing state is. Alternatively, the control unit 86 determines that 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, the bather may be in a predetermined bathing state that may become abnormal. To do. At this time, the control unit 86 operates the water supply device 26. More specifically, the control unit 86 opens the solenoid valve 32 to open the hot water filling pipe 62. In the present embodiment, when the absolute value of the bather's heart rate becomes equal to or higher than the first threshold value, the solenoid valve 32 is opened, but the change (increase) in the bather's heart rate is predetermined. The solenoid valve 32 may be opened when the heart rate changes (increases) or more. Similarly, in the present embodiment, when the absolute value of the blood pressure of the bather becomes equal to or higher than the second threshold value, the solenoid valve 32 is opened, but the change (increase) in the blood pressure of the bather is increased. The solenoid valve 32 may be opened when the blood pressure changes (increases) or more than a predetermined value.

After opening the solenoid valve 32, the control unit 86 closes the solenoid 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, about 36 ° C, which is the body temperature), or when the additional water stop button 112 is pressed, the control unit 86 may perform the addition. In addition, the solenoid valve 32 is closed to stop the water addition.

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

<Reheating operation>
When the bathtub 18 is filled with hot water, the hot water filling pipe 62 is closed by the solenoid valve 32. When the reheating button 106 of the remote controller 72 shown in FIG. 3 is pressed while the bathtub 18 is filled (reserved) with hot water, the control unit 80 of the remote controller 72 shown in FIG. 2 via the communication unit 88. A reheating command signal is output to the control unit 74. When the control unit 86 of the control unit 74 detects the reheating command signal, the control unit 86 enters the reheating mode.

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

When the circulation pump 42 operates, as shown by arrow A, the hot water in the bathtub 18 is sucked from the suction port 20B of the circulation port 20, and the sucked hot water is reheated by the heat source machine 14 through the reheating return pipe 16B. It is returned to the heat exchanger 52 of the unit 44. Further, the hot water returned to the heat exchanger 52 is heated by the gas burner 54, and the heated hot water is discharged from the discharge port 20A of the circulation port 20 to the bathtub 18 through the reheating outbound pipe 16A as shown by the arrow A. It is discharged inside.

The reheating return pipe 16B is provided with a hot water temperature sensor 64, and the hot water temperature sensor 64 outputs a temperature detection signal according to the temperature of the hot water flowing through the reheating return pipe 16B. Then, during the reheating 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 the set value set as the predetermined reheating temperature. The above operation is repeated until the temperature of the hot water reaches the set reheating temperature. As a result, the hot water in the bathtub 18 is reheated.

<When heat shock prevention mode is set>
In the bathroom system 10, when the heat shock prevention mode button 114 of the remote controller 72 is pressed, the heat shock prevention mode button 114 lights up to enter the heat shock prevention mode (see FIG. 3). In this state, even if the setting button (not shown) of the remote controller 72 is pressed to set the temperature of the hot water in the bathtub 18 to a predetermined temperature (for example, 41 ° C.) or higher, the signal of the setting button is not accepted. To cancel the heat shock prevention mode, for example, by pressing and holding the heat shock prevention mode button 114, the heat shock prevention mode button 114 is turned off.

When the temperature of the hot water detected by the hot water temperature sensor 64 is equal to or higher than a predetermined temperature (for example, 41 ° C.) while the heat shock prevention mode button 114 is pressed, the control unit 86 controls the hot water in the bathtub 18. Control is performed so that the temperature becomes lower than the predetermined temperature. For example, the control unit 86 heats the hot water supply unit 46 of the heat source machine 14 so that hot water having a temperature lower than a predetermined temperature (for example, 41 ° C.) is stored in the bathtub 18 when the bathtub 18 is filled with hot water. To control. As a result, it is possible to prevent the temperature of the hot water in the bathtub 18 from becoming higher than a predetermined temperature (for example, 41 ° C.), which is a condition in which the bather is likely to suffer from heat stroke. Can be prevented.

Further, for example, the control unit 86 operates the water supply device 26 after the hot water is stored in the bathtub 18. More specifically, as shown in FIG. 5, the control unit 86 opens the hot water filling pipe 62 by the opening operation of the solenoid valve 32. As a result, as shown by arrow B, water flows from the water supply unit 30 to the water supply pipe 28 due to the water supply pressure of the water supply, and further water flows to the hot water filling pipe 62 via the hot water supply unit 46 to reheat and return. Divided by pipe 16B. At this time, the gas burner 60 of the hot water supply unit 46 is not ignited. Then, as shown by the arrow B, water flows through the reheating return pipe 16B in the direction opposite to that at the time of reheating, and water is supplied into the bathtub 18 from the suction port 20B of the circulation port 20. At the same time, as shown by the arrow C, water flows from the reheating return pipe 16B to the reheating outward pipe 16A via the heat source machine 14, and water is supplied into the bathtub 18 from the discharge port 20A of the circulation port 20. .. As a result, the additional water is added at a temperature lower than that of the hot water in the bathtub 18. At this time, the reheating unit 44 of the heat source machine 14 is stopped (the gas burner 54 of the reheating unit 44 is not ignited). Therefore, the temperature of the hot water in the bathtub 18 becomes lower than the predetermined temperature (for example, 41 ° C.). Therefore, it is possible to prevent the temperature of the hot water in the bathtub 18 from becoming higher than a predetermined temperature, which is a condition in which the bather is likely to suffer from heat stroke, and it is possible to prevent the bather from suffering from heat stroke. it can.

When the temperature of the hot water detected by the hot water temperature sensor 64 is equal to or higher than a predetermined temperature (for example, 41 ° C.) while the heat shock prevention mode button 114 is pressed, the control unit 86 adds the remote controller 72. Even if the burning button 106 is pressed, the reheating mode is not executed. Therefore, it is possible to prevent the hot water in the bathtub 18 from being reheated and circulated in the circulation pipe 16 by the operation of the heat source machine 14, and the temperature of the hot water in the bathtub 18 becoming higher than that.

<At the time of abnormality detection>
The control unit 86 enters the water supply mode when it determines that an abnormality has been detected under predetermined conditions based on the biological information detected by the biological information sensor 94 (see FIG. 2 and the like). In the present embodiment, for example, when it is determined that an abnormality is detected under a predetermined condition when the heat shock prevention mode button 114 is not pressed, the water supply mode is set. For example, when the control unit 86 detects that there is no movement of the bather for a certain period of time or more based on the position information of the bather in the bathtub 18 detected by the human sensor as the biometric information sensor 94, the biometric information When the heart rate of the bather detected by the heart rate sensor as the sensor 94 becomes equal to or higher than the first threshold value as an example of a predetermined heart rate, the bather detected by the blood pressure sensor as the biometric information sensor 94. The information that can be read from the electrocardiogram of the bather when the blood pressure of the above becomes equal to or higher than the second threshold value as an example of the predetermined blood pressure or detected by the electrocardiogram sensor as the biometric information sensor 94 satisfies a certain condition. When, 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 control unit 86 opens the hot water filling pipe 62 by the opening operation of the solenoid valve 32. As a result, as shown by arrow B, water flows from the water supply unit 30 to the water supply pipe 28 due to the water supply pressure of the water supply, and further water flows to the hot water filling pipe 62 via the hot water supply unit 46 to reheat and return. Divided by pipe 16B. At this time, the gas burner 60 of the hot water supply unit 46 is not ignited. Then, as shown by the arrow B, water flows through the reheating return pipe 16B in the direction opposite to that at the time of reheating, and water is supplied into the bathtub 18 from the suction port 20B of the circulation port 20. At the same time, as shown by the arrow C, water flows from the reheating return pipe 16B to the reheating outward pipe 16A via the heat source machine 14, and water is supplied into the bathtub 18 from the discharge port 20A of the circulation port 20. .. As a result, the additional water is added at a temperature lower than that of the hot water in the bathtub 18. At this time, the reheating unit 44 of the heat source machine 14 is stopped (the gas burner 54 of the reheating unit 44 is not ignited).

Here, the control of the water supply system 12 of the present embodiment will be described more specifically.

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 an abnormality is detected in step 130, the control unit 86 opens the solenoid valve 32 and opens the hot water filling pipe 62 in step 132. As a result, additional water is started. On the other hand, if the occurrence of an abnormality is not detected in step 130, step 130 is repeated until the occurrence of an abnormality is detected.

Further, in step 134, the control unit 86 calculates the amount of added water (target value). More specifically, the control unit 86 predicts the current amount and temperature of 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, etc.), and determines the predetermined temperature (for example). For example, the amount of added water (target value) below the body temperature of about 36 ° C.) is calculated.

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

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

Then, in step 136, it is determined whether or not the water has been added up to the target value. In the present embodiment, the amount of hot water is predicted from the water level of the hot water 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 is added to the target value and the water is completed, the solenoid valve 32 is closed and the hot water filling pipe 62 is closed in step 138. As a result, the additional water is stopped. On the other hand, if it is not determined in step 136 that the water added to the target value is completed, the step 136 is repeated until the water added to the target value is completed.

Further, in step 140, the circulation pump 42 is operated (turned on). As a result, hot water is circulated from the bathtub 18 to the reheating return pipe 16B and the reheating outward pipe 16A. Next, in step 142, it is determined whether or not 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, about 36 ° C. which is the body temperature).

If it is determined in step 142 that 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, about 36 ° C. which is the body temperature), the end determination criterion is set in step 144. Whether or not it is satisfied is determined. As the end determination criteria, for example, when the safety of the bather is detected by the biological information sensor 94, or when the water addition stop button 112 (see FIG. 3) of the remote controller 72 is pressed, the bather returns or is found. There are cases. If it is determined in step 144 that the end determination criterion is satisfied, the operation of the circulation pump 42 is stopped (turned off) in step 146.

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

In the bathroom system 10 described above, when the biological information sensor 94 detects a predetermined bathing state, the control unit 86 operates the water supply device 26 to add water at a temperature lower than that of the hot water in the bathtub 18. Do. As a result, the temperature of the hot water in the bathtub 18 is lower than that before the water supply. Therefore, for example, when the bather is bathing under conditions that tend to lose consciousness, the temperature of the hot water in the bathtub 18 can be lowered as compared with that before the water supply.

In such a bathroom system 10, when the temperature of hot water detected by the hot water temperature sensor 64 is equal to or higher than a predetermined temperature (for example, 41 ° C.) while the heat shock prevention mode button 114 is pressed, the water supply system 12 The temperature of the hot water in the bathtub 18 is controlled to be lower than a predetermined temperature. Therefore, it is possible to prevent the temperature of the hot water in the bathtub 18 from becoming higher than a predetermined temperature, which is a condition in which the bather is likely to suffer from heat stroke, and prevent the bather from suffering from heat stroke. Can be done.

When the temperature of the hot water detected by the hot water temperature sensor 64 is equal to or higher than a predetermined temperature (for example, 41 ° C.) while the heat shock prevention mode button 114 is pressed, the control unit 86 adds the remote controller 72. Even if the burning button 106 is pressed, the reheating mode is not executed. Therefore, it is possible to prevent the temperature of the hot water in the bathtub 18 from becoming higher than that.

Further, in the bathroom system 10, when the biological information sensor 94 detects a predetermined bathing state, the control unit 86 operates the water supply device 26 to add water at a temperature lower than that of the hot water in the bathtub 18. Do. Therefore, when the bather is bathing under conditions that easily cause him to lose consciousness, the temperature of the hot water in the bathtub 18 can be lowered as compared with that before the water supply, and heat stroke of the bather can be prevented or prevented. If the bather has a slight heat stroke, he / she can be restored early. Further, since the water supply device 26 is connected to the reheating circulation pipe 16 (in this embodiment, the reheating return pipe 16B), the reheating circulation pipe 16 is used rather than the hot water in the bathtub 18. Water can be added at a low temperature.

Further, in the bathroom system 10, 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, and a blood pressure sensor that detects the blood pressure of the bather. And at least one of the electrocardiogram sensors for detecting the electrocardiogram of the bather. The control unit 86 operates the water supply device 26 based on the bathing state of the bather based on the information detected by at least one of the heart rate sensor, the motion sensor, the blood pressure sensor, and the electrocardiogram sensor. As a result, for example, when the heart rate or blood pressure of the bather is higher than the permissible value, or when the bather does not move, the water can be added at a temperature lower than that of the hot water in the bathtub 18.

The bathroom system 10 is provided with a remote controller 72 in which a speaker 100 for outputting sound is arranged in the bathroom 22, and the control unit 86 is charged with hot water in the bathtub 18 before operating the water supply device 26. The speaker 100 may notify the bather that the additional water is to be added. As a result, it is possible to avoid sudden addition of water to the hot water in the bathtub 18 without notifying the bather in advance.

[Second Embodiment]
Next, the bathroom system 150 of the second embodiment of the present invention will be described with reference to FIG. 7. The same components as those in the first embodiment described above will be assigned the same number and the description thereof will be omitted.

As shown in FIG. 7, the bathroom system 150 includes a water supply system 152 as a temperature control means. In addition to the water supply device 26, the water supply system 152 includes a drainage actuator 154 as an opening / closing means for opening and closing a drainage plug (automatic drainage plug) 36 that closes the drainage port 34 at the bottom of the bathtub 18. The control unit 86 (see FIG. 2) of the control unit 74 controls the operation of the drainage actuator 154. In the present embodiment, when the bathtub 18 is filled with hot water, the drain plug 36 closes the drain port 34 by the drain actuator 154. Further, when the control unit 86 (see FIG. 2) operates the water supply device 26 to add water to the bathtub 18, the drainage actuator 154 opens the drainage plug 36 to open the drainage port 34. As a result, the hot water in the bathtub 18 is drained from the drain port 34, and the water supply device 26 adds water at a temperature lower than that in the bathtub 18.

In the bathroom system 150 provided with the above water supply system 152, it is possible to prevent the hot water in the bathtub 18 from increasing or overflowing when the water is added to the bathtub 18. Further, even when the bather loses consciousness or has a slight heat stroke, it is possible to prevent the bather from drowning in the bathtub 18.

[Third Embodiment]
Next, the bathroom system 160 of the third embodiment of the present invention will be described with reference to FIGS. 8 and 9. The same components as those of the first and second embodiments described above will be assigned the same number and the description thereof will be omitted.

As shown in FIG. 8, the bathroom system 160 includes a water supply system 162 as a temperature control means. The water supply system 162 is not provided with the biometric information sensor 94 mounted on the remote controller 72 of the water supply system 12 (see FIG. 2) of the first embodiment. In the water supply system 162, the control for operating the water supply device 26 is different from that in the water supply system 12 of the first embodiment. The overall configuration of the water supply system 162 of the present embodiment is the same as the overall configuration of the water supply system 12 of the first embodiment shown in FIG.

FIG. 9 is a flowchart of the control system of the water supply system 162 of the present 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 to the bathtub 18 in order 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 bathing of the bather is detected in the bathtub 18. The control unit 86 (see FIG. 8) detects that a bather has taken a bath in the bathtub 18 based on the water level information of the hot water detected by the water level sensor 66. For example, when the water level of hot water detected by the water level sensor 66 rises sharply, it is because a bather has entered the bathtub 18, and it is determined that bathing is detected (there is a bather). When bathing is detected, the time from the start of bathing is measured by the timer 90 (see FIG. 8) as a bathing time measuring means. If no bathing is 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 the bath has been bathed in hot water having a temperature equal to or higher than the threshold value for a predetermined time. In general, it is said that long-term soaking in hot water causes heat shock (heat stroke), according to the materials released by the Consumer Affairs Agency (January 20, 2016). Is recommended as a safe bathing method to "rise in less than 10 minutes with hot water below 41 ° C". In the present embodiment, in step 172, it is determined whether or not the bath has been bathed in hot water having a temperature equal to or higher than the threshold value (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) for measuring the bathing time of the bather in the bathtub 18 function as "bathing state detecting means". There is. 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 the threshold value (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 bath has been bathed in hot water having a temperature equal to or higher than the threshold value (for example, 40 ° C.) for a predetermined time (for example, 10 minutes), the speaker 100 (see FIG. 8) of the remote controller 72 is used in step 174. Outputs information that calls attention. For example, the speaker 100 outputs information that calls attention, such as "Please get out of the bath because a bathing accident may occur."

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 or not there is a bather in the bathtub 18 based on the water level information of the hot water detected by the water level sensor 66. For example, when the water level of the hot water detected by the water level sensor 66 drops sharply, it is because a bather has come out of the bathtub 18, and it is determined that the bather is absent. If it is determined in step 176 that the bather is absent, the control of the water supply system of the present embodiment is terminated.

On the other hand, if it is determined in step 176 that the bather is not absent, it is determined in step 178 whether or not a certain period of time has passed after the alert. In the present embodiment, it is determined whether or not a certain time (for example, 3 minutes) has passed after the alert. If it is determined in step 178 that a certain period of time has not passed since the alert was issued, the process returns to step 176.

If it is determined in step 178 that a certain period of time has passed after calling attention, in step 180, the speaker 100 of the remote controller 72 notifies that water is added to the bathtub 18. In the present embodiment, the speaker 100 notifies information such as "Because there is a risk of a bathing accident, water is added to the bathtub."

Next, in step 182, the solenoid valve 32 (see FIG. 8) is opened to operate the water supply device 26. As a result, additional water is added to the bathtub 18.

In the bathroom system 160 provided with the water supply system 162 of the present embodiment, when the bath is bathed in hot water having a temperature equal to or higher than the threshold value (for example, 40 ° C.) for a predetermined time (for example, 10 minutes), a warning is issued, and then. When the bath is continuously bathed for a certain period of time (for example, 3 minutes), water is forcibly added to the bathtub 18. Therefore, it is possible to prevent the bather from becoming abnormal, that is, a bathing accident such as heat stroke.

Further, in the bathroom system 160 of the present embodiment, for example, when the speaker 100 of the remote controller 72 notifies that the hot water in the bathtub 18 is discharged in step 180, the bather manually performs the remote controller 72 (see FIG. 3). By pressing the water addition stop button 112, the water addition may be forcibly stopped in the bathtub 18.

Although the bathroom system 160 of the present embodiment is not provided with the biometric information sensor, a biometric information sensor 94 may be provided instead of this configuration. That is, by providing the biological information sensor 94, as in the bathroom system 10 of the first embodiment, when an abnormal state of the bather is detected, water may be added to the bathtub 18.

[Fourth Embodiment]
Next, the bathroom system 200 of the fourth embodiment of the present invention will be described with reference to FIG. The same components as those in the first to third embodiments described above will be assigned the same number and the description thereof will be omitted.

<During normal operation>
In the bathroom system 200 provided with the above water supply system 202, water flows from the water supply unit 214 to the water supply pipe 212 by opening the pipe 204 by opening the solenoid valve 216 during normal hot water filling. It is supplied to the hot water supply unit 46 of the heat source machine 14. In the hot water supply unit 46, the water is heated by igniting the gas burner 60. Further, the heated hot water flows through the pipe 204 and is supplied into the bathtub 18 from the supply port 206. Then, with the hot water stored in the bathtub 18, the piping 204 is closed by the closing operation of the solenoid valve 216. When it is desired to raise the temperature of the hot water in the bathtub 18 at the time of bathing, the hot water in the bathtub 18 is supplied from the hot water supply unit 46 of the heat source machine 14 through the pipe 204 and mixed with the hot water in the bathtub 18. The temperature rises.

<When heat shock prevention mode is set>
In the bathroom system 200, when the heat shock prevention mode button 114 of the remote controller 72 is pressed, the heat shock prevention mode button 114 lights up to enter the heat shock prevention mode (see FIG. 3). In this state, even if the temperature of the hot water in the bathtub 18 is set to a predetermined temperature (for example, 41 ° C.) or higher by the setting button (not shown) of the remote controller 72, the setting button does not operate.

When the temperature of the hot water detected by the hot water temperature sensor 64 is equal to or higher than a predetermined temperature (for example, 41 ° C.) while the heat shock prevention mode button 114 is pressed, the control unit 86 controls the hot water in the bathtub 18. Control is performed so that the temperature becomes lower than the predetermined temperature. For example, the control unit 86 heats the hot water supply unit 46 of the heat source machine 14 so that hot water having a temperature lower than a predetermined temperature (for example, 41 ° C.) is stored in the bathtub 18 when the bathtub 18 is filled with hot water. To control. As a result, it is possible to prevent the temperature of the hot water in the bathtub 18 from becoming higher than a predetermined temperature (for example, 41 ° C.), which is a condition in which the bather is likely to suffer from heat stroke. Can be prevented.

Further, for example, the control unit 86 operates the water supply device 210 after the hot water is stored in the bathtub 18. The control unit 86 opens the pipe 204 by opening the solenoid valve 216. As a result, due to the water supply pressure of the water supply, 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. Will be done. At that time, the gas burner 60 of the hot water supply unit 46 is not ignited. As a result, the additional water is added at a temperature lower than that of the hot water in the bathtub 18. Therefore, the temperature of the hot water in the bathtub 18 becomes lower than the predetermined temperature (for example, 41 ° C.). Therefore, it is possible to prevent the temperature of the hot water in the bathtub 18 from becoming higher than a predetermined temperature, which is a condition in which the bather is likely to suffer from heat stroke, and it is possible to prevent the bather from suffering from heat stroke. it can.

<At the time of abnormality detection>
In the water supply system 202, when an abnormal state is detected, the solenoid valve 216 is opened and the water supply device 210 is operated. As a result, 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 into the bathtub 18 from the supply port 206 in the bathtub 18 through the pipe 204. At that time, since the gas burner 60 of the hot water supply unit 46 is not ignited, additional water is added to the bathtub 18 at a temperature lower than that of the hot water in the bathtub 18.

In the above water supply system 202, the temperature of the hot water in the bathtub 18 is lower than that before the water supply because the water is added to the bathtub 18 at a temperature lower than that in the hot water in the bathtub 18. Therefore, for example, when the bather is bathing in a condition where he / she is likely to lose consciousness, the temperature of the hot water in the bathtub 18 is lowered as compared with that before the water supply to prevent the bather from heat stroke or to prevent heat stroke. If the bather has a slight heat stroke, he / she can be restored early.
