Description

  The present invention relates to a bathroom system capable of taking appropriate measures when a bather stuns.

As a specific example of the bathroom system, there is one described in Patent Document 1.
In the bathroom system described in this document, a human body detection device capable of detecting the movement of the bather is installed in the bathroom. For example, if the bather faints (faints) and the bather stops moving, 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 determination is made, the remote control outside the bathroom is notified that an abnormality has occurred in the bather. As a result, a person outside the bathroom will notice an abnormality in the bathroom, which is preferable for the rescue and protection of bathers.

  However, the prior art still has room for improvement as described below.

In other words, when an abnormality occurs such as the bather fainting in the bathroom, it is only necessary that the other person can immediately rush to the bathroom. Here, if the abnormality described above occurs in a cold time such as winter, and the bather stuns in the bathroom for a relatively long time, hypothermia may occur as the bathroom temperature decreases. . It is desired to eliminate such fear as much as possible.
On the other hand, in the prior art, it is difficult to appropriately respond to the above-mentioned demand because only the fact that an abnormality has occurred is reported outside the bathroom, and there is still room for improvement in this respect.

JP 2005-25625 A

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

  In order to solve the above problems, the present invention takes the following technical means.

  The bathroom system provided by the present invention detects a movement of a bather in the bathroom and outputs a detection signal thereof, and a state in which the movement of the bather is not or less than a predetermined time occurs. Control means for determining that a predetermined abnormality has occurred in the bather based on the detection signal, and heat supply means capable of supplying heat into the bathroom so as to warm the bather in the bathroom Whether or not the bather has a possibility of hypothermia when the control means determines that the abnormality has occurred in the bather. And when it is determined that there is a possibility of hypothermia, the heat supply means is operated to supply heat into the bathroom with this determination as a trigger. It is characterized by that.

According to such a configuration, the following effects can be obtained.
In other words, if an abnormality occurs such as the bather fainting in the bathroom, if the bather is likely to have hypothermia, the heat supply means is activated and heat is supplied into the bathroom. In addition, a decrease in the body temperature of the bather is appropriately suppressed. Therefore, even if it takes a long time for a bather to run into the bathroom after a certain abnormality occurs in a cold season, such as in winter, the bather may experience hypothermia during that period. Can be appropriately prevented or suppressed.

  In the present invention, preferably, the determination as to whether or not there is a possibility of becoming hypothermic is a determination that there is a possibility of becoming hypothermia when the temperature of the bathroom is equal to or lower than a predetermined temperature. is there.

  According to 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, a drain valve is provided for discharging hot water from the bathtub in the bathroom to the outside of the bathtub, and the control means causes the abnormality to occur in the bather, and the bather When it is determined that there is a possibility of hypothermia, it is determined where the bather is present in the bathroom, and in this determination, it is determined that the bather is present in the bathtub. When it is done, the drain valve is configured to be opened.

  According to such a configuration, it is possible to appropriately prevent a bather who has fainted in the bathtub from sinking in the hot water of the bathtub.

  In the present invention, preferably, as the heat supply means, a hot water supply device is provided, and after the drain valve is opened and the hot water in the bathtub is drained, the drain valve remains open, It is comprised so that the warm water of a predetermined | prescribed temperature range may be supplied in the said bathtub from the said hot water supply apparatus.

  According to such a configuration, when hot water in a predetermined temperature range is supplied into the bathtub, the hot water is poured into the bather who is stunned in the bathtub, and the bather is operated. It is possible to warm up. 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 sinks into the hot water.

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

  According to such a configuration, the following effects can be obtained. That is, 36.5-37.5 ° C. corresponds to the deep body temperature of a healthy person. For this reason, if the hot water of such temperature is utilized, it becomes possible to warm a bather appropriately so that the temperature of the hot water does not become too high or too low.

  In the present invention, preferably, the heat supply unit includes a hot water supply device, and the control unit may cause the abnormality in the bather and the bather may have hypothermia. When the determination is made, it is determined in which part of the bathroom the bather is present, and in this determination, if it is determined that the bather is present in the bathroom wash area, the hot water supply device Is operated, and a hot water filling operation to the bathtub in the bathroom or a reheating operation of hot water existing in the bathtub is performed.

  According to such a configuration, an effect of increasing the temperature of the entire bathroom can be expected by performing hot water filling in the bathtub or reheating operation of hot water existing in the bathtub. Therefore, warming the bather present in the washing area and preventing hypothermia can be appropriately realized by simple means.

  In the present invention, preferably, as the heat supply means, a bathroom dryer is provided, and in the control means, the abnormality may occur in the bather, and the bather may have hypothermia. When it is determined that the hot air is blown from the bathroom dryer into the bathroom.

  According to such a configuration, it is possible to appropriately warm the bather by hot air blowing without questioning whether the bather who is fainting is present in the bathtub in the bathroom or in the washing place. .

  In the present invention, preferably, the control means can determine whether or not the bather's body is wet with water, and when determining that the bather's body is wet with water, The warm air blowing is configured to be performed toward a position avoiding the bather.

  According to such a configuration, it is possible to appropriately avoid the possibility that the body temperature of the bather is lowered by the hot air blowing. That is, when the bather's body is wet with water, if the hot air is blown directly to the bather, the bather's body may be rejected and cooled, but according to the above configuration, such a risk is avoided. Is possible.

  In the present invention, preferably, the heat supply means includes a mist supply means. In the control means, the abnormality may occur in the bather, and the bather may have hypothermia. When it is determined that the hot water mist is supplied from the mist supply means into the bathroom.

  According to such a structure, a bather can be warmed actively using warm water mist, and hypothermia can be prevented appropriately.

  In the present invention, preferably, the control means can determine whether or not the bather's face is facing the mist supply means, and the bather's face is the mist supply means. When it is determined that the hot water mist is directed, the supply of the hot water mist is not executed.

  According to such a configuration, it is possible to appropriately avoid the problem that a lot of mist hits various places on the face of the bather who is fainting and the like, and this causes water droplets.

  In the present invention, preferably, the control means activates the heat supply means when it is determined that the abnormality has occurred in the bather and the bather may have hypothermia. Sometimes, the ventilation fan installed in the bathroom is turned off.

  According to such a configuration, the following effects can be obtained. That is, when the heat supply unit is operated to prevent hypothermia of the bather, if the ventilation fan is turned on, it becomes difficult to raise the temperature of the bathroom at an early stage. There is a fear. On the other hand, according to the said structure, since a ventilation fan is made into an OFF state, it is possible to eliminate the above-mentioned fear appropriately.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present 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), (b) is a top view which shows typically the state which abnormality occurred in the bather in the bathroom system. It is a flowchart which shows an example of the operation control procedure performed in the bathroom system shown in FIG. It is a flowchart which shows an example of the operation control procedure performed in addition to the operation control procedure shown in FIG. It is principal 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.

A bathroom system BS shown in FIG. 1 includes a bathroom 1 having a bathtub 10 and a washing place 11 adjacent thereto, a hot water supply apparatus 2 capable of supplying hot water into the bathtub 10, and a bathroom dryer 3 installed on the ceiling of the bathroom 1. And 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 injection nozzle 4 corresponds to a specific example of “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 the hardware configuration itself is the same as that conventionally known, and includes a control unit 20 that controls the operation of each unit, and the control unit 20. Are provided with a bathroom remote controller 21A and a kitchen remote controller 21B, an outside air temperature sensor Sd, and the like. The hot water supply device 2 is connected to the circulation adapter 10a of the bathtub 10 through a piping portion 29 (forward pipe and return pipe), so that the hot water filling operation to the bathtub 10 and the follow-up of hot water accumulated in the bathtub 10 are performed. Can be whispered. The drain port 10b at the bottom of the bathtub 10 is provided with a drain valve V1 (drain plug) as an on-off valve that is remotely controlled by the control unit 20, 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, and is, for example, an image sensor (infrared camera) using a pyroelectric element, and includes an infrared image in the bathroom 1 including a bather. Imaging is possible. The human body detection sensor Sa may be capable of detecting a water flow in a shower. The imaging range of the human body detection sensor Sa is substantially the entire area in the bathroom 1. In the case where an image of substantially the entire area of the bathroom 1 cannot be captured by one human body detection sensor Sa, a configuration in which a plurality of human body detection sensors Sa are provided can be employed. Further, the human body detection sensor Sa may be provided in a part different from the bathroom remote control 21A. An 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 “control means” in the present invention. In this control unit 20, based on the output signal from the human body detection sensor Sa, the position of the bather, the presence / absence of movement, and the like are determined, and the bather is, for example, fainted and stopped moving, or has little movement, If the movement amount is below a predetermined level for a predetermined time, it is determined that an abnormality has occurred in the bather. Thereafter, it is determined whether or not the bather may have hypothermia, and various operation processes described later are executed. Preferably, the control unit 20 is configured to be able to determine the position of the bather's head, the orientation of the face, and the like.

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 accommodates these.
The fan 31 sucks air in the bathroom 1 from an air supply port 35 provided in the ceiling portion of the bathroom 1 and causes air to be blown into the bathroom 1 via a 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. Heating hot water can be supplied from the hot water supply device 2 to the heat exchanger 32 for heating, for example, and warm air is blown from the louver 33 into the bathroom 1 when such hot water is supplied. When heating hot water is not supplied, air blowing as so-called cold air blowing is possible. The louver 33 can change the angle by driving the motor M <b> 1, and can change the direction of air blowing from the louver 33.

  The mist ejection nozzle 4 is assembled in the bathroom dryer 3. 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 piping section 40 for mist. The water supply pipe section 40 is also provided with a heating section 41 capable of heating hot water passing through the inside. For this reason, as a kind of mist, either the hot water mist which made the hot water heated by the heating part 41 mist, or the non-hot water mist which made the non-heating hot water 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, for example, similarly to the heat exchanger 32 for heating. 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 operations 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 an 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 be described.

  First, the control unit 20 of the hot water supply device 2 is preferably configured so that the human body detection sensor Sa is always driven on and the presence or absence of a bather in the bathroom 1 and the presence of a bather in the bathroom 1 are changed. Monitoring (S1). In such a monitoring state, when a bather faints or the like, the movement is stopped or a state in which only a slight movement occurs occurs, and when such a state continues for a predetermined time, at least the bathroom remote control 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 body by detecting the alarm, so in this case the bather No determination is made that an abnormality has occurred (S5: NO, S1).

  In spite of the alarm being issued, if the bather does not move or the state is still continued for a predetermined time thereafter, the control unit 20 determines that the bather is abnormal (S5: YES, S6). In this case, the fact that there is an abnormality in the bather is notified in a manner that can be visually and audibly recognized using at least the kitchen remote controller 21B, and the operation of the hot water supply device 2 is stopped (S7). That is, when hot water filling to the bathtub 10 or bathing is performed, such operation is stopped. The above notification can be made to a communication device different from the kitchen remote control 21B, such as a portable communication terminal. When a notification that an abnormality has occurred is detected by the bather's family, for example, and the bathroom remote controller 21A or the kitchen remote controller 21B is operated, the control unit 20 cancels the previous determination that an abnormality has occurred in the bather. At the same time, the above-described notification operation is stopped, and the original state before the occurrence of 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 the bather is present in the bathtub 10 or not. It is determined in the unit 20 (S8: YES, S9). FIG. 2A shows an example where the bather is present in the bathtub 10, and FIG. 2B shows an example where the bather is present in the washing area 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 hot water from the bathtub 10 (S9: YES, S10). If the drain valve V1 is opened and the water level of the bathtub 10 is lowered, it is possible to prevent a bather who is fainted from sinking in the hot water of the bathtub 10. As long as there is a bather in the bathtub 10, the control for opening the drain valve V <b> 1 can be configured to always be performed without determining whether hot water is present in the bathtub 10. 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. .

  Thereafter, the control unit 20 determines whether or not the bather may have hypothermia (S11). In this determination, for example, if the bathroom temperature detected using the temperature sensor Sb is equal to or lower than a predetermined temperature Ta (for example, 25 ° C.), it is determined that the bather may have hypothermia. The predetermined temperature Ta does not necessarily have to be a constant value. For example, when the outside air temperature is low and the bathroom temperature is likely to be lowered early, the predetermined temperature Ta may be increased. . Since there is an individual difference in the likelihood of becoming hypothermia, the user may be able to change the predetermined temperature Ta as a threshold as appropriate. Moreover, you may add parameters other than bathroom temperature as a judgment element of whether there is a possibility of becoming hypothermia.

  When it is determined that the bather may have hypothermia, the ventilating fan 5 is turned off so that the heat in the bathroom 1 does not escape a lot (S11: YES, S12), The following operation control is also executed.

  That is, when the 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 supplied from the mist ejection nozzle 4. Mist is ejected (S13: YES, S14, S15).

  The above-mentioned hot water supply to the bathtub 10 is performed with the drain valve V1 in the open state, and the hot water temperature is set to a range of 36.5 to 37.5 ° C., for example, the deep body temperature of a healthy person. If hot water is supplied from the circulation adapter 10a into the bathtub 10 in a state where the bather is present in the bathtub 10, at least a part of this hot water is applied to the bather's body, or the bather's body is placed in the bathtub 10. You can expect to touch the hot water supplied on the bottom of the. Therefore, it is possible to warm the bather. In addition to warming the bathtub 10, the warm water also warms the air in the bathroom 1, so that it is also possible to suppress a decrease in body temperature of the bather. If the temperature of the hot water is in the range of 36.5 to 37.5 ° C., the bather will not be damaged even if the hot water is applied to the bather, and the body temperature of the bather is maintained at the original body temperature. It is suitable for doing. Since the hot water supplied into the bathtub 10 passes through the drain port 10b and the drain valve V1 and is drained, and the water level of the bathtub 10 does not increase, the bather may be submerged in the hot water of the bathtub 10. Again, it is 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 comprised so that it may also be judged whether a part may sink in the hot water of the bathtub 10. FIG. In this determination, when it is determined that the bather's head 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 in the open state, a situation may occur in which the hot water in the bathtub 10 cannot be smoothly drained, for example, because the drain port 10b is blocked by the body of the bather. According to the above-described operation control, it is possible to appropriately cope with such a situation.

  The warm air blowing from the bathroom dryer 3 and the hot water mist ejection from the mist ejection nozzle 4 raise the bathroom temperature. For this reason, it becomes possible to prevent more thoroughly that a bather's body temperature falls and it becomes hypothermia.

  Here, preferably, the control unit 20 can determine whether or not the body of the bather is wet with water, and if it is determined that the bather is wet with water, the warm air blowing from the bathroom dryer 3 is The control is performed so as to be performed toward the washing place 11. If the bather is present in the tub 10, if the bath 10 has been filled with water before or after the bathing operation, the bather is immersed in the hot water of the tub 10, and the body is water. It is possible to judge that it is wet. When the bather's body is wet with water, if hot air is blown toward the bather, the bather may be rejected and cooled, but according to the control described above, such a risk may occur. It is possible to eliminate it.

  More preferably, the control unit 20 can determine the orientation 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. The mist ejection from the mist ejection nozzle 4 is controlled so as not to be performed. It is not preferable that a lot of mist hits the face of the bather who is fainting, and this is not preferable. However, according to the control, such a situation is appropriately avoided.

  Unlike the above, when a bather who has stunned is present in the washing place 11, heating of hot water accumulated in the bathtub 10 (bath bathing) or hot water supply into the bathtub 10 is performed. (S13: NO, S17). Further, 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 described above is heated or the hot water is supplied into the bathtub 10, the hot water in the bathtub 10 becomes a heat source, and as a result, the bath temperature can be raised. Since the bather exists in the washing place 11, the bath 10 may store hot water at a slightly higher temperature, and the amount of hot water can be increased. It should be noted that heating of the hot water accumulated in the bathtub 10 (bath-up of the bath) is performed with the drain valve V1 in a closed state, but hot water supply into the bathtub 10 is also preferably closed. It is performed in the state.

  Similarly to the case of step S15 described above, the above-described warm air blow and hot water mist jet also raise the bathroom temperature, so that the bather existing in the washing place 11 is warmed, and hypothermia is prevented. Effective above.

  Preferably, when the bather's body is wet with warm air, the hot air is blown toward the bathtub 10 so that the hot air does not hit the bather, and the bather's face is When facing the mist ejection nozzle 4, the mist ejection is not performed. The effect obtained by such control is the same as the effect described in relation to step S15.

When there is a bather in the washing area 11, whether or not the bather's body is wet with water is whether the bather has been soaked in the hot water of the tub 10 before that or not, and whether or not the bather is using It is possible to judge based on whether or not. More specifically, after the bather enters the bathroom 1, if there is a relatively large change in the water level of the bathtub 10 without hot water from the hot water supply device 2, It is possible to estimate that the bather's body is wet with water. In addition, when using a shower, 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 was used after the bather entered the bathroom 1, It can be determined that the bather's body 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. This is, for example, the supply of hot water to the bathtub 10, the blowing of hot air, and the ejection of hot water mist. Each operation is not always executed continuously. For example, when the bathroom temperature rises to a temperature range where there is no possibility of developing hypothermia, the above-mentioned operations are temporarily interrupted. Also good. If the possibility of hypothermia occurs again after this interruption, the hot water supply, hot air blowing, or hot water mist ejection may be resumed.

  When there is no possibility that the bather who has fainted will have 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 determination, for example, when a heat stroke index such as a heat index (WBGT) or a heat index (HI) in the bathroom 1 is equal to or higher than a predetermined value, A method such as judging that there is a possibility is adopted. Since the likelihood of heat stroke is not only temperature but also humidity (relative humidity) greatly affects, it is necessary to use a heat stroke index (may be a rough numerical value) with both bathroom temperature and humidity as factors. desired. For this purpose, the bathroom remote controller 21A is also provided with a humidity sensor Sc.

  When it is determined that the bather may have heat stroke, the control unit 20 performs an operation for lowering the body temperature of the bather (S31: YES, S32). This operation is, for example, cool air blowing from the bathroom dryer 3 or ejection of non-hot water mist from the mist ejection nozzle 4. Moreover, when the bather who produced fainting etc. exists in the bathtub 10, the hot water of the range of 36.5-37.5 degreeC is supplied in the bathtub 10 in the state which the drain valve V1 opened, It is also effective to bring this hot water into a so-called flowing state. Since 36.5 to 37.5 ° C. hot water coincides with the deep body temperature of a healthy person, hot water in this temperature range not only exhibits a hypothermia prevention effect for bathers, but also exhibits a heat stroke prevention effect. To 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. At that time, the corresponding operation as described above is executed (S31: NO, S33).

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

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

  According to such a structure, when the water level of the bathtub 10 is higher than the circulation adapter 10a, the hot water of the bathtub 10 is drained outside from the drain valve V3, and the water level of the bathtub 10 is lowered to the height of the circulation adapter 10a. Is possible. Although the total amount of hot water in the bathtub 10 cannot be drained to the outside, if the water level of the bathtub 10 is lowered as described above, the bather who has stunned in the bathtub 10 may sink in the hot water. The effect of reducing is obtained. The drainage valve referred to in the present invention is not necessarily limited to that provided at the drainage port 10b of the bathtub 10, and may be provided in a manner as in the present embodiment.

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

  In the above-described embodiment, whether or not a bather who has fainted may have hypothermia is determined based on the bathroom temperature. However, as described above, parameters other than the bathroom temperature are determined. You may judge using.

  In the above-mentioned embodiment, when there is a possibility that the bather may have hypothermia, each means of hot water supply from the hot water supply device to the bathtub, hot air blowing from the bathroom dryer, and hot water mist supply 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. In addition, as a means for directly or indirectly warming a bather who may have hypothermia, a means different from the above-described means may be employed. For example, means for ejecting hot water from a shower head or means for heating the interior of the bathroom by turning on the heater when the heating apparatus is installed on the side wall or under the floor of the bathroom may be employed. A mist ejection nozzle is not limited to what was assembled | attached to the bathroom dryer.
