Description

The present invention relates to a bathroom system capable of taking appropriate countermeasures when a bather faints or the like.

As a specific example of the bathroom system, there is one described in Patent Document 1.
In the bathroom system described in the same document, a human body detection device capable of detecting the movement of the bather is installed in the bathroom. For example, when the bather faints (faints) and the bather becomes immobile, this is the human body. It is detected by a predetermined control means via the detection device, and it is determined that an abnormality has occurred in the bather. When such a judgment is made, the remote controller outside the bathroom is notified that an abnormality has occurred in the bather. As a result, a person outside the bathroom becomes aware of the abnormality in the bathroom, which is preferable for the rescue and protection of the bather.

However, in the above-mentioned prior art, there is still room for improvement as described below.

That is, when an abnormality such as fainting of a bather occurs in the bathroom, it is sufficient if another person can immediately rush to the bathroom, but it may not be the case. Here, if the above-mentioned abnormality occurs in a cold season such as winter and the bather continues to faint in the bathroom for a relatively long period of time, hypothermia may develop as the bathroom temperature decreases. .. It is desired to eliminate such a risk as much as possible.
On the other hand, in the above-mentioned prior art, it is difficult to appropriately respond to the above-mentioned request because it is only notified to the outside of the bathroom that an abnormality has occurred, and there is still room for improvement in this respect.

Japanese Unexamined Patent Publication No. 2005-25625

The present invention has been conceived under the above-mentioned circumstances, and appropriately prevents or suppresses the bather from becoming hypothermic when an abnormality such as fainting of the bather occurs. The challenge is to provide a bathing system that can be used.

In order to solve the above problems, the following technical means are taken in the present invention.

The bathroom system provided by the first aspect of the present invention includes a human body detecting means capable of detecting the movement of a bather in the bathroom and outputting the detection signal, and the bather does not move for a predetermined time or longer. Alternatively, when a small number of conditions occur, the control means for determining that a predetermined abnormality has occurred in the bather based on the detection signal and the heat supply to the bathroom so as to warm the bather in the bathroom. A bathroom system comprising a possible heat supply means, wherein the control means may cause the bather to have hypothermia if the bather determines that the abnormality has occurred. If it is determined whether or not there is a bath, and if it is determined that there is a possibility of hypothermia, the heat supply means is activated to supply heat to the bathroom. The control means is provided with a drain valve for draining hot water from the bathroom tub to the outside of the tub, and the control means is such that the bather has the abnormality and the bather is low. When it is determined that there is a possibility of body temperature, it is determined in which part of the bathroom the bather is present, and in this determination, it is determined that the bather is present in the bathtub. In this case, the drain valve is configured to be open, and a hot water supply device is provided as the heat supply means. The drain valve is opened and the hot water in the bath is drained. After that, it is characterized in that the hot water supply device is configured to supply hot water in a predetermined temperature range from the hot water supply device while the drain valve is in the open state .

With such a configuration, the following effects can be obtained.
That is, if an abnormality such as fainting of the bather occurs in the bathroom and the bather may have hypothermia, the heat supply means is activated and heat is supplied to the bathroom. , The decrease in body temperature of the bather is appropriately suppressed. Therefore, in cold weather such as winter, even if it takes a long time for another person to rush to the bathroom after a certain abnormality occurs in the bather, the bather has hypothermia during that period. It is possible to appropriately prevent or suppress this.
In addition, it is possible to appropriately prevent a bather who has fainted in the bathtub from drowning in the hot water of the bathtub.
Furthermore, by supplying hot water in a predetermined temperature range to the bathtub, it is possible to warm the bather by allowing the bather who has fainted in the bathtub to act in a flowing state. .. Since the drain valve remains open, it is possible to appropriately avoid a situation in which a large amount of hot water accumulates in the bathtub and the bather drowns in the warm water.

In the present invention, preferably, the determination as to whether or not the hypothermia may occur is based on the determination that the bathroom may have hypothermia when the temperature of the bathroom is equal to or lower than a predetermined temperature. be.

With such a configuration, it is possible to easily and accurately determine whether or not a bather who has fainted in the bathroom has hypothermia.

In the present invention, preferably, the temperature of the hot water supplied from the hot water supply device into the bathtub after the hot water in the bathtub is drained is in the range of 36.5 to 37.5 ° C.

With such a configuration, the following effects can be obtained. That is, 36.5 to 37.5 ° C. corresponds to the core body temperature of a healthy person. Therefore, if hot water having such a temperature is used, it is possible to appropriately warm the bather by preventing the temperature of the hot water from becoming too high or too low.

The bathroom system provided by the second aspect of the present invention includes a human body detecting means capable of detecting the movement of a bather in the bathroom and outputting the detection signal, and the bather does not move for a predetermined time or longer. Alternatively, when a small number of conditions occur, the control means for determining that a predetermined abnormality has occurred in the bather based on the detection signal and the heat supply to the bathroom so as to warm the bather in the bathroom. A bathroom system comprising a possible heat supply means, wherein the control means may cause the bather to have hypothermia if the bather determines that the abnormality has occurred. If it is determined whether or not there is a bath, and if it is determined that there is a possibility of hypothermia, the heat supply means is activated to supply heat to the bathroom. The bather is equipped with a hot water supply device as the heat supply means, and the control means determines that the bather may have the abnormality and the bather may have hypothermia. At that time, it is determined in which part of the bathroom the bather is present, and if it is determined in this determination that the bather is present in the washing place of the bathroom, the hot water supply device is used. It is characterized in that it operates and is configured to perform a hot water filling operation in the bathroom tub or a reheating operation of hot water existing in the tub.

According to such a configuration, the effect of raising the temperature of the entire bathroom can be expected by performing the hot water filling operation in the bathtub or the reheating operation of the hot water existing in the bathtub. Therefore, it is possible to appropriately warm the bathers present in the washing place to prevent hypothermia by simple means.

The bathroom system provided by the third aspect of the present invention is a human body detecting means capable of detecting the movement of a bather in the bathroom and outputting the detection signal, and the bather does not move for a predetermined time or longer. Alternatively, when a small number of conditions occur, the control means for determining that a predetermined abnormality has occurred in the bather based on the detection signal and the heat supply to the bather so as to warm the bather in the bather. A bathroom system comprising a possible heat supply means, wherein the control means may cause the bather to have hypothermia if the bather determines that the abnormality has occurred. If it is determined whether or not there is a bath, and if it is determined that there is a possibility of hypothermia, this determination is used as an opportunity to activate the heat supply means to supply heat to the bathroom. The bather is provided with a bathroom dryer as the heat supply means, and the bather may have the abnormality and the bather may have hypothermia in the control means. When it is determined, the bath dryer is configured to blow warm air into the bathroom, and the control means can determine whether or not the bather's body is wet with water. When it is determined that the body of the bather is wet with water, the warm air blower is characterized in that it is configured to be directed toward a position avoiding the bather.

According to such a configuration, it is possible to appropriately warm the bather by blowing warm air regardless of whether the bather who has fainted or the like is present in the bathtub or the washing place of the bathroom. ..
Further, according to such a configuration, it is possible to appropriately avoid the possibility that the body temperature of the bather is lowered by the warm air blowing. That is, when the bather's body is wet, if warm air is blown directly to the bather, the bather's body may be rather cooled, but according to the above configuration, such a risk is avoided. It is possible to do.

The bathroom system provided by the fourth aspect of the present invention is a human body detecting means capable of detecting the movement of a bather in the bathroom and outputting the detection signal, and the bather does not move for a predetermined time or longer. Alternatively, when a small number of conditions occur, the control means for determining that a predetermined abnormality has occurred in the bather based on the detection signal and the heat supply to the bather so as to warm the bather in the bather. A bathroom system comprising a possible heat supply means, wherein the control means may cause the bather to have hypothermia if the bather determines that the abnormality has occurred. If it is determined whether or not there is a bath, and if it is determined that there is a possibility of hypothermia, this determination is used as an opportunity to activate the heat supply means to supply heat to the bathroom. The bather is provided with a mist supply means as the heat supply means, and the bather may have the abnormality and the bather may have hypothermia in the control means. When it is determined, the hot water mist is supplied from the mist supply means into the bathroom, and the control means determines whether or not the face of the bather faces the mist supply means. When it is determined that the bather's face is facing the mist supply means, the hot water mist is not supplied. There is.

According to such a configuration, the bather can be positively warmed by using the hot water mist, and hypothermia can be appropriately prevented.
Further, according to such a configuration, it is possible to appropriately avoid the problem that a large amount of mist hits various parts of the face of the bather who has fainted and the like, and the mist becomes water droplets.

In the present invention, preferably, the control means activates the heat supply means because it is determined that the bather has the abnormality and the bather may have hypothermia. Occasionally, the ventilation fan attached to the bathroom is turned off.

With such a configuration, the following effects can be obtained. That is, if the ventilation fan is temporarily turned on when the heat supply means is operated to prevent hypothermia in the bather, it becomes difficult to raise the temperature of the bathroom at an early stage. There is a risk. On the other hand, according to the above configuration, since the ventilation fan is turned off, the above-mentioned possibility can be appropriately eliminated.

Other features and advantages of the invention will become more apparent from the following description of embodiments of the invention with reference to the accompanying drawings.

It is a schematic sectional drawing which shows an example of the bathroom system which concerns on this invention. (A) and (b) are plan views schematically showing a state in which an abnormality has occurred in a bather in a bathroom system. It is a flowchart which shows an example of the operation control procedure executed in the bathroom system shown in FIG. It is a flowchart which shows an example of the operation control procedure which is executed in addition to the operation control procedure shown in FIG. It is a main part explanatory drawing which shows the other example of this invention.

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

The bathroom system BS shown in FIG. 1 includes a bathroom 1 having a bathtub 10 and a washing area 11 adjacent thereto, a hot water supply device 2 capable of supplying hot water into the bathtub 10, and a bathroom dryer 3 installed on the ceiling of the bathroom 1. , At least one mist ejection nozzle 4, and a ventilation fan 5.
Each of the hot water supply device 2, the bathroom dryer 3, and the mist ejection nozzle 4 corresponds to a specific example of the "heat supply means" in the present invention.

The hot water supply device 2 is, for example, an instantaneous gas hot water supply device or an oil hot water supply device, and its hardware configuration itself is the same as that conventionally known, and a control unit 20 for controlling the operation of each part, this control unit 20. It is equipped with a bathroom remote controller 21A and a kitchen remote controller 21B, and an outside temperature sensor Sd, which are communicated with each other. The hot water supply device 2 is connected to the circulation adapter 10a of the bathtub 10 via a piping portion 29 (outward pipe and return pipe), and is used to fill the bathtub 10 with hot water and to follow the hot water stored in the bathtub 10. Burning operation is possible. A drain valve V1 (drain plug) as an on-off valve remotely controlled by the control unit 20 is provided at the drain port 10b at the bottom of the bathtub 10, and so-called automatic drainage of hot water in the bathtub 10 is possible.

The bathroom remote controller 21A is provided with a temperature sensor Sb for detecting the temperature (room temperature) of the bathroom 1 and a human body detection sensor Sa. The human body detection sensor Sa corresponds to an example of the "human body detection means" in the present invention, for example, an image sensor (infrared camera) using a pyroelectric element, and an infrared image in the bathroom 1 including a bather. Imaging is possible. The human body detection sensor Sa may be able to detect the water flow of the shower and the like. The imaging range of the human body detection sensor Sa is set to be substantially the entire area in the bathroom 1. When it is not possible to take an image of substantially the entire area of the bathroom 1 by one human body detection sensor Sa, it is possible to configure a plurality of human body detection sensors Sa. Further, the human body detection sensor Sa may be provided at a portion different from that of the bathroom remote controller 21A. The output signal (captured image data) from the human body detection sensor Sa is sent to the control unit 20 of the hot water supply device 2.

The control unit 20 corresponds to an example of the "control means" in the present invention. In this control unit 20, the position of the bather, the presence or absence of movement, etc. are determined based on the output signal from the human body detection sensor Sa, and the bather is, for example, fainted and stuck, or there is little movement. If the amount of movement is below a predetermined level for a predetermined time, it is determined that an abnormality has occurred in the bather. After that, it is determined whether or not the bather may have hypothermia, and various motion processes described later are executed. Preferably, the control unit 20 is configured so that the position of the head of the bather, the orientation of the face, and the like can be determined.

The bathroom dryer 3 includes a fan 31, a heat exchanger 32 for heating, a louver 33, a control unit 30 that controls the operation of each part of the bathroom dryer 3, and a housing 34 that houses these.
The fan 31 sucks the air in the bathroom 1 from the air supply port 35 provided on the ceiling of the bathroom 1 and blows the air into the bathroom 1 through the louver 33 provided in the air outlet. The heating heat exchanger 32 is a heating means for heating the air sucked into the fan 31 from the air supply port 35. Hot water can be supplied to the heating heat exchanger 32 from, for example, the hot water supply device 2, and when such hot water is supplied, hot air is blown from the louver 33 into the bathroom 1. When the heated hot water is not supplied, air can be blown as so-called cold air. The angle of the louver 33 can be changed by driving the motor M1, and the direction of air blown from the louver 33 can be changed.

The mist ejection nozzle 4 is assembled in the bathroom dryer 3. The mist ejection from the mist ejection nozzle 4 can be switched on and off by opening and closing the on-off valve V2 provided in the water supply pipe portion 40 for mist. The water supply piping unit 40 is also provided with a heating unit 41 capable of heating hot water passing through the inside. Therefore, as the type of mist, either hot water mist in which hot water heated by the heating unit 41 is made into a mist or non-hot water mist in which unheated hot water is made into a mist can be selected. The heating unit 41 can be a heat exchanger that receives hot water supply from the hot water supply device 2, similar to, for example, the heating heat exchanger 32. The angle of the mist ejection nozzle 4 can be freely changed by driving the motor M2, and the mist ejection direction from the mist ejection nozzle 4 can be changed.

The ventilation fan 5 is provided by using the housing 34 of the bathroom dryer 3, and can suck the air in the bathroom 1 from the air supply port 35 and exhaust it to the outside. The operation of the ventilation fan 5 and the bathroom dryer 3 can be controlled by the control unit 20 of the hot water supply device 2.

Next, an example of the operation processing procedure executed in the bathroom system BS described above will be described with reference to the flowcharts shown in FIGS. 3 and 4, and the operation thereof will also be described.

First, the control unit 20 of the hot water supply device 2 preferably keeps the human body detection sensor Sa in a constantly driven on state, and determines whether or not there is a bather in the bathroom 1 and its movement when there is a bather in the bathroom 1. It is being monitored (S1). In such a monitoring state, if the bather faints and the movement stops or only slightly moves, and such a state continues for a predetermined time, at least the bathroom remote controller at that time. From 21A, a visually or audibly recognizable alarm is issued (S2: YES, S3: YES, S4). If there is no abnormality in the bather and the bather simply stops moving for a while, the bather will move his / her body by detecting the above-mentioned alarm. In this case, the bather It is not determined that an abnormality has occurred in (S5: NO, S1).

If the bather does not move or remains low for a predetermined time after the alarm is issued, the control unit 20 determines that the bather has an abnormality (S5: YES, S6). In this case, the fact that there is an abnormality in the bather is notified at least in a visually and audibly recognizable manner by using the kitchen remote controller 21B, and the operation of the hot water supply device 2 is stopped (S7). That is, when the bathtub 10 is filled with hot water or the bath is reheated, such an operation is stopped. The above-mentioned notification can be made to be performed to a communication device other than the kitchen remote controller 21B, for example, a portable communication terminal or the like. When the notification that an abnormality has occurred is detected by, for example, the bather's family and the bathroom remote controller 21A or the kitchen remote controller 21B is operated, the control unit 20 cancels the previous determination that the bather has an abnormality. At the same time, the notification operation described above is stopped, and the initial state before the occurrence of the original abnormality is restored (S8: NO, S20, S1).

On the other hand, unlike the above, when the bathroom remote controller 21A or the kitchen remote controller 21B is not operated despite the notification that an abnormality has occurred, it is controlled whether or not the bather is present in the bathtub 10. Judgment is made in unit 20 (S8: YES, S9). FIG. 2A shows an example when the bather is present in the bathtub 10, and FIG. 2B shows an example when the bather is present in the washing place 11.

In the above determination, when it is determined that the bather is present in the bathtub 10, the drain valve V1 is opened to drain the hot water of the bathtub 10 (S9: YES, S10). By opening the drain valve V1 and lowering the water level of the bathtub 10, it is possible to prevent a bather who has fainted or the like from drowning in the hot water of the bathtub 10. The control for opening the drain valve V1 may be configured to always be executed as long as there is a bather in the bathtub 10 without determining whether or not hot water is present in the bathtub 10. It is possible. In the flowchart of FIG. 3, when the bather is present in the washing place 11, the operation of opening the drain valve V1 is not executed (S9: NO), but the present invention is not limited to this, and the drain valve V1 may be opened. ..

After that, the control unit 20 determines whether or not the bather may have hypothermia (S11). In this determination, for example, if the bathroom temperature detected by using the temperature sensor Sb is a predetermined temperature Ta (for example, 25 ° C.) or less, it is determined that the bather may have hypothermia. The predetermined temperature Ta does not necessarily have to be a constant value, and may be changed according to the outside air temperature, for example, when the outside air temperature is low and the bathroom temperature tends to be low at an early stage, the predetermined temperature Ta may be increased. .. Since there are individual differences in the susceptibility to hypothermia, the user may appropriately change the predetermined temperature Ta, which is a threshold value. In addition, parameters other than the bathroom temperature may be added as a factor for determining whether or not there is a possibility of hypothermia.

When it is determined that the bather may have hypothermia, the ventilation fan 5 is turned off to prevent a large amount of heat in the bathroom 1 from escaping to the outside (S11: YES, S12). The following operation control is also executed.

That is, when a bather is present in the bathtub 10, hot water is supplied from the hot water supply device 2 to the bathtub 10, hot air is blown from the bathroom dryer 3, and hot water is blown from the mist ejection nozzle 4. Mist is ejected (S13: YES, S14, S15).

The hot water supply to the bathtub 10 is performed with the drain valve V1 open, and the hot water temperature is in the range of 36.5 to 37.5 ° C., which is the core body temperature of a healthy person, for example. If hot water is supplied from the circulation adapter 10a into the bathtub 10 while the bather is present in the bathtub 10, at least a part of the hot water is applied to the bathtub's body or the bather's body is in the bathtub 10. You can expect to touch the hot water supplied on the bottom of the bathtub. Therefore, it is possible to warm the bather. Since the hot water not only warms the bathtub 10 but also warms the air in the bathroom 1, it is possible to suppress a decrease in the body temperature of the bather. If the temperature of the hot water is in the range of 36.5 to 37.5 ° C., even if the bather is exposed to the hot water, the bather will not be damaged and the bather's body temperature will be maintained at the original temperature. Suitable for bathing. The hot water supplied into the bathtub 10 is drained through the drain port 10b and the drain valve V1, and the water level of the bathtub 10 does not rise. Therefore, the bather may drown in the hot water of the bathtub 10. , Again properly prevented.

Although not shown in the flowchart, preferably, the control unit 20 determines the position of the bather's head and the water level of the bathtub 10 when supplying the hot water into the bathtub 10, and the bather's head. It is also configured to determine whether or not the portion may sink in the hot water of the bathtub 10. In this judgment, if it is determined that the head of the bather may sink in the hot water of the bathtub 10, the hot water supply to the bathtub 10 is stopped. Even when the drain valve V1 is opened, a situation may occur in which the hot water in the bathtub 10 cannot be drained smoothly because, for example, the drain port 10b is blocked by the body of the bather. According to the above-mentioned operation control, even when such a situation occurs, it can be suitably dealt with.

The hot air blown from the bathroom dryer 3 and the hot water mist ejected from the mist ejection nozzle 4 raise the bathroom temperature. Therefore, it becomes possible to more thoroughly prevent the body temperature of the bather from falling and hypothermia.

Here, preferably, the control unit 20 can determine whether or not the bather's body is wet with water, and when it is determined that the bather's body is wet, the warm air blown from the bathroom dryer 3 is blown. , Controlled to be done towards the washroom 11. When the bather is present in the bathtub 10, if the bathtub 10 has been filled with hot water or reheated in the bathtub before that, the bather is immersed in the hot water of the bathtub 10 and his body is watered. It is possible to judge that it is wet. If the bather's body is wet and warm air is blown toward the bather, the bather may be cooled rather than the bather, but according to the above-mentioned control, such a risk may occur. It is possible to eliminate it.

Further, more preferably, the control unit 20 can determine the direction of the bather's face based on the signal from the human body detection sensor Sa, and the bather's face faces the mist ejection nozzle 4. Is controlled so that the mist is not ejected from the mist ejection nozzle 4. It is not preferable that a large amount of mist hits the face of a bather who has fainted and becomes water droplets, but such control appropriately avoids such a situation.

Unlike the above, when a bather who has fainted or the like is present in the washing place 11, the hot water stored in the bathtub 10 is heated (bath reheating) or hot water is supplied into the bathtub 10. (S13: NO, S17). In addition, warm air is blown from the bathroom dryer 3, and hot water mist is ejected from the mist ejection nozzle 4 (S18).

If the hot water in the bathtub 10 is heated or the hot water is supplied into the bathtub 10, the hot water in the bathtub 10 becomes a heat source and raises the bathroom temperature, so that the bather can be warmed. Since the bather is present in the washing place 11, hot water having a slightly higher temperature may be stored in the bathtub 10, and the amount of hot water can be increased. It goes without saying that the heating of the hot water stored in the bathtub 10 (bath reheating) is performed with the drain valve V1 closed, but the hot water supply into the bathtub 10 is also preferably performed with the drain valve V1 closed. It is done in the state of being drained.

The above-mentioned hot air blowing and hot water mist ejection also raise the bathroom temperature as in the case of step S15 described above, so that the bathers present in the washing place 11 are warmed and hypothermia is prevented. Effective on.

Preferably, when the body of the bather is wet with hot air, the hot air is blown to the bathtub 10 side so that the hot air does not hit the bather, and the face of the bather is blown. When facing the mist ejection nozzle 4, no mist ejection is performed. The effect obtained by such control is similar to the effect described in connection with step S15.

When there is a bather in the washing place 11, whether or not the bather's body is wet is whether or not the bather has been immersed in the hot water of the bathtub 10 before that, and whether or not the bather is using the shower. It is possible to judge by such things as. More specifically, after the bather enters the bathroom 1, if there is a relatively large change in the water level of the bathtub 10 in a state where the hot water is not supplied from the hot water supply device 2, the bather has the hot water of the bathtub 10. It is possible to presume that the bather was soaked in water, and it is possible to determine that the bather's body is wet. Further, when a shower is used, it is possible to detect the heat, the water flow of the shower, etc. by the human body detection sensor Sa, and if there is a history that the shower has been used after the bather entered the bathroom 1. It is possible to judge that the body of the bather is wet with water.

The operation control for preventing hypothermia as described above ends when a predetermined switch operation is performed by someone in the bathroom remote controller 21A or the kitchen remote controller 21B (S16: YES, S19). The operation control for preventing hypothermia is continuously executed until the predetermined switch operation described above is performed, which includes hot water supply to the bathtub 10, hot air blowing, hot water mist ejection, and the like. It does not mean that each operation is always performed continuously. For example, when the bathroom temperature rises to a temperature range where hypothermia is unlikely to occur, each operation described above is temporarily interrupted. May be good. If the possibility of hypothermia reoccurs after this interruption, the hot water supply, hot air blast, or hot water mist eruption described above may be resumed.

If the bather who has fainted or the like is unlikely to develop hypothermia, the control unit 20 further determines whether or not there is a possibility of heat stroke (S11: NO, S31 in FIG. 4). In this judgment, for example, when the heat stroke index such as the heat index (WBGT: Wet-Bulb Globe Temperature) or the heat index (HI) in the bathroom 1 is equal to or higher than a predetermined value, the heat stroke is determined. Techniques such as determining that there is a possibility are adopted. Since the susceptibility to heat stroke is greatly affected not only by temperature but also by humidity (relative humidity), it is advisable to use a heat stroke index (a rough numerical value may be used) that takes both bathroom temperature and humidity as factors. desired. As a means for that, the bathroom remote controller 21A is also provided with a humidity sensor Sc.

When the control unit 20 determines that the bather may suffer from heat stroke, the control unit 20 executes an operation for lowering the body temperature of the bather (S31: YES, S32). This operation is, for example, cold air blowing from the bathroom dryer 3 or ejection of non-warm water mist from the mist ejection nozzle 4. When a bather who has fainted or the like is present in the bathtub 10, hot water in the range of, for example, 36.5 to 37.5 ° C. is supplied into the bathtub 10 with the drain valve V1 open. It is also effective to put this hot water in a so-called flowing state. Since hot water at 36.5 to 37.5 ° C matches the core body temperature of a healthy person, hot water in this temperature range not only exerts a hypothermia-preventing effect on bathers, but also exerts a heat stroke-preventing effect. do.

On the other hand, if it is determined that there is no possibility of heat stroke, the control unit 20 continuously determines whether or not there is a possibility of hypothermia or heat stroke, and any possibility occurs. If so, the corresponding operation as described above is executed at that time (S31: NO, S33).

FIG. 5 shows another embodiment of the present invention. In the figure, the same or similar elements as those in the embodiment are designated by the same reference numerals as those in the embodiment, and the duplicate description thereof will be omitted.

In the embodiment shown in FIG. 5, the drain valve 10b of the bathtub 10 is not provided with a drain valve that can be remotely controlled. However, the piping portion 29 is provided with a drain valve V3 such as a three-way valve that can be remotely controlled.

According to such a configuration, when the water level of the bathtub 10 is higher than that of the circulation adapter 10a, the hot water of the bathtub 10 can be drained to the outside from the drain valve V3 and the water level of the bathtub 10 can be lowered to the height of the circulation adapter 10a. It is possible. Although it is not possible to drain the entire amount of hot water in the bathtub 10 to the outside, if the water level in the bathtub 10 is lowered as described above, there is a risk that a bather who has fainted in the bathtub 10 will be drowned in the hot water. The effect of reducing is obtained. The drain valve referred to in the present invention is not necessarily limited to the one provided at the drain port 10b of the bathtub 10, and may be provided in an embodiment as in the present embodiment.

The present invention is not limited to the contents of the above-described embodiments. The specific configuration of each part of the bathroom system according to the present invention can be variously redesigned within the scope of the present invention.

In the above-described embodiment, whether or not a bather who has fainted may develop hypothermia is determined based on the bathroom temperature, but as described above, parameters other than the bathroom temperature are used. May be judged using.

In the above-described embodiment, when the bather may have hypothermia, each means of supplying hot water from the water heater to the bathtub, blowing hot air from the bathroom dryer, and supplying hot water mist from the mist ejection nozzle. However, it is not necessary that all of these means are adopted, and if at least one of these means is adopted, it is included in the technical scope of the present invention .
