Description

The present invention relates to a bathroom system in which it is possible to take 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 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 a bather fainting in the bathroom occurs, 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 hot season such as summer and the bather is stunned in the bathroom for a relatively long period of time, the bather may suffer from heat stroke. 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 only notifies the bather that an abnormality has occurred outside the bathroom, and there is still room for improvement in this respect. be.

In the present invention, preferably, the determination as to whether or not there is a possibility of heat stroke is determined based on the temperature and humidity of the bathroom, and the heat stroke index indicating the susceptibility to heat stroke is predetermined. If it is the above, it is judged that there is a possibility of heat stroke.
Here, as the heat stroke index, for example, a heat index (WBGT: Wet-Bulb Globe Temperature), a heat index (HI), or an index similar thereto can be used.

According to such a configuration, it is possible to easily and accurately determine whether or not a bather who has fainted in the bathroom suffers from heat stroke. Since the susceptibility to heat stroke is greatly affected by humidity (relative humidity), the heat stroke index that considers not only room temperature but also humidity was used as a factor for determining whether or not heat stroke occurs. In some cases, it is possible to accurately determine whether or not there is a possibility of heat stroke.

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

It is the 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 explanatory drawing of the main part 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 "cooling medium 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 unit, the control unit 20. It is equipped with a bathroom remote controller 21A and a kitchen remote controller 21B, and an outside air temperature detection 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 pipe 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) remotely controlled by the control unit 20 is provided at the drain port 10b at the bottom of the bathtub 10, and by opening the drain valve V1, the so-called automatic drainage of the bathtub 10 is performed. Is possible.

The bathroom remote controller 21A is provided with a temperature sensor Sb and a humidity sensor Sc for detecting the temperature and humidity of the bathroom 1, respectively, 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 captures an infrared image of the bathroom 1 including a bather. It 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 defined as substantially the entire area in the bathroom 1. When it is not possible to image an substantially entire area of the bathroom 1 with 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 the control unit 20, the position of the bather, the presence or absence of movement, and the like are determined based on the output signal from the human body detection sensor Sa, and the bather is, for example, fainted and does not move, 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 suffer from heat stroke, 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 it out 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 heat exchanger 32 from, for example, the hot water supply device 2, and when such hot water is supplied, warm air is blown from the louver 33 into the bathroom 1. When the heated hot water is not supplied to the heat exchanger 32, unheated air can be blown as so-called cold air blower. 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 corresponds to an example of the "mist supply means" in the present invention, and 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 ejection. The water supply pipe unit 40 is also provided with a heating unit 41 capable of heating hot water passing through the inside. Therefore, as a type of mist, there are a hot water mist in which hot water heated by the heating unit 41 is turned into a mist, and a mist of unheated water in which hot water not heated is made into a mist. One can be selected as appropriate. The heating unit 41 can be, for example, a heat exchanger that receives hot water supply from the hot water supply device 2 in the same manner as the heating heat exchanger 32. The angle of the mist ejection nozzle 4 can be 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 even after the alarm is issued, the control unit 20 determines that the bather has an abnormality (S5: YES, S6). In this case, at least the kitchen remote controller 21B notifies that the bather has an abnormality in a visually and audibly recognizable manner, and the operation of the hot water supply device 2 is stopped (S7). When the bathtub 10 is filled with hot water or the bath is reheated, such an operation is stopped. It is also possible to perform the above-mentioned notification 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 terminated, and the initial state before the occurrence of the abnormality is restored (S8: NO, S20, S1).

On the other hand, unlike the above, if the bathroom remote controller 21A or the kitchen remote controller 21B is not operated even though the bather has been notified that an abnormality has occurred, whether or not the bather is present in the bathtub 10. Is determined by the control 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). 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 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.

After that, the control unit 20 determines whether or not the bather may suffer from heat stroke (S11). In this determination, the heat index (WBGT) is first obtained based on the temperature and humidity (relative humidity) of the bathroom 1 detected by using the temperature sensor Sb and the humidity sensor Sc, and the obtained heat index is predetermined. Whether or not it is greater than or equal to the value is determined. The heat index is an example of the "heat stroke index" in the present invention, but when the heat index is 28 ° C, it is a strict caution line for heat stroke, and if it exceeds this, there is a possibility of heat stroke. Increases significantly. Therefore, from the viewpoint of providing a margin for bather protection, it is judged that, for example, if the heat index is 27 ° C. or higher, the bather may suffer from heat stroke. Of course, since there are individual differences in the susceptibility to heat stroke, the value of the heat index used as a threshold value may be appropriately changed by the user.
As a method for judging the possibility of heat stroke, it is also possible to use other heat stroke indexes such as the heat index (HI), or to judge based only on the bathroom temperature, as described later. be.

When it is determined that the bather may suffer from heat stroke, the ventilation fan 5 is turned on to prevent heat and humidity from being trapped in the bathroom 1 (S11: YES, S12), and the following Such operation control is also executed.

That is, when a bather is present in the bathtub 10, hot water is supplied into the bathtub 10 (S13: YES, S14). At that time, the drain valve V1 is left in the open state. The temperature of hot water is within a predetermined range, for example, in the range of 36.5 to 37.5 ° C., which is the core body temperature of a healthy person. 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 hung on 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 cool the bather and suppress the rise in the body temperature of the bather. If the hot water temperature is 36.5 to 37.5 ° C, which corresponds to the core body temperature range of a healthy person, the bather's body will not be excessively cooled and the bather's body temperature will be within the original normal range. Suitable for maintaining body temperature.
As a result of the hot water supplied into the bathtub 10 passing through the drain valve V1 and being drained, the water level of the bathtub 10 does not rise, so that there is no risk of the bather drowning in the hot water.

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 determination, if it is determined that the head of the bather may sink into the hot water of the bathtub 10, the supply of hot water 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, such a situation can be suitably dealt with.

As described above, the operation of draining the hot water of the bathtub 10 and then supplying the hot water of the predetermined temperature range to the bathtub 10 is performed only when the bather is present in the bathtub 10. On the other hand, preferably, the operation of opening the drain valve V1 is executed even when the bather is present in the washing place 11 (S13: NO, S18). If such an operation is executed, even if hot water having a high temperature is accumulated in the bathtub 10, the hot water is discharged to the outside of the bathroom, so that the hot water in the bathtub 10 causes the bathroom 1 to be discharged. It is possible to prevent the temperature and humidity of the bathroom 1 from rising, and to prevent the heat index of the bathroom 1 from rising.

When it is determined that there is a possibility of heat stroke, in addition to the above-mentioned operation control, unheated air is blown from the bathroom dryer 3 and mist of unheated water is ejected from the mist ejection nozzle 4. Is done (S15). These actions are performed regardless of the position of the bather in the bathtub 10 or the washing place 11, and the synergistic action of the air blower and the mist actively cools the bather's body, resulting in heat stroke. It is possible to prevent this from happening.

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 air blower from the bathroom dryer 3 is bathed. It is controlled so that it is performed in a position that avoids people. That is, when the bather is present in the bathtub 10, the air blower is directed toward the washing place 11, and when the bather is present in the washing place 11, the air blower is directed toward the bathtub 10. .. If the bather's body is wet and air is blown directly to the bather, the bather's body may be overcooled, but control can eliminate such a risk. Is.

Whether or not the bather's body is wet can be determined based on the operation history of each part of the bathroom system BS. For example, if the bather is currently present in the bathtub 10, the bather is immersed in the hot water of the bathtub 10 if the bathtub 10 has been filled with hot water or the bath has been reheated before that. Therefore, it can be determined that the body is wet with water. On the other hand, when the bather is currently present in the washing place 11, the water level of the bathtub 10 changes relatively large after the bather enters the bathroom 1 in a state where the hot water supply device 2 does not supply hot water. If there is, it is possible to presume that the bather was immersed in the hot water of the bathtub 10, and it is possible to determine that the bather's body is wet with water. In addition, when a shower is used, it is possible to detect the heat, water flow of the shower, etc. by the human body detection sensor Sa, and there is a history that the shower was used after the bather entered the bathroom 1. For example, it can be determined that the bather's body is wet with water.

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 ejected. It is not very desirable that a large amount of mist hits the face of a bather who has fainted and becomes water droplets, but according to the above control, such a thing can be appropriately avoided. ..

The operation control for preventing heat stroke as described above ends when a predetermined switch operation is performed by the bather himself / herself or his / her family in the bathroom remote controller 21A or the kitchen remote controller 21B (S16: YES, S17). The operation control for preventing heat stroke is continuously executed until the predetermined switch operation described above is performed, which is the supply of hot water to the bathtub 10.
It does not mean that each operation such as air blowing and mist ejection of unheated water is always continuously executed. For example, when the heat index drops to a band where there is little or no possibility of developing heat stroke, each of the above-mentioned actions may be temporarily interrupted. If the possibility of heat stroke reoccurs after this interruption, each of the above-mentioned operations may be resumed.

If the bather who has fainted or the like is unlikely to suffer from heat stroke, the control unit 20 also determines whether or not there is a possibility of hypothermia (S11: NO, S31 in FIG. 4). In this determination, for example, the bathroom temperature is used as a criterion, and when the bathroom temperature is equal to or lower than a predetermined temperature Tb (for example, 25 ° C.), it is determined that there is a possibility of hypothermia. When determining the possibility of hypothermia, it is almost unnecessary to consider humidity, and it is possible to accurately determine the possibility of hypothermia based only on the bathroom temperature. However, other factors such as outside air temperature may be added to the criterion.

When the control unit 20 determines that the bather may have hypothermia, the control unit 20 executes an operation for warming the bather (S31: YES, S32). This operation is, for example, blowing warm air from the bathroom dryer 3 or ejecting hot 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 works to prevent heat stroke in bathers, but also prevents hypothermia. It also exerts an action to do.

Unlike the above, when it is determined that there is no possibility of hypothermia, the control unit 20 continuously determines whether or not there is a possibility of heat stroke or hypothermia, and is enthusiastic. When the possibility of illness or hypothermia arises, the above-mentioned corresponding actions are performed (S31: NO, S33).

FIG. 5 shows another embodiment of the present invention. In the figure, elements that are the same as or similar to those of the embodiment are designated by the same reference numerals as those of the embodiment, and 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 section 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 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 intended by the present invention.

In the above-described embodiment, whether or not there is a possibility of heat stroke is determined based on the heat index (WBGT), but the present invention is not limited to this. The heat stroke index referred to in the present invention is a numerical value obtained based on at least two parameters of bathroom temperature and humidity, and is a numerical value as an index indicating the susceptibility to heat stroke. As the heat stroke index, for example, the heat index (HI) adopted by the US National Weather Service can also be used. It is also possible to use other indices similar to these. The heat stroke index can be calculated from the temperature and humidity of the bathroom, but by storing the data showing the correspondence between them in the memory, the heat stroke index should be calculated with reference to this data. You may do it. The heat stroke index can also be an approximate value.

Further, in the present invention, the possibility of heat stroke can be determined by using a parameter different from the heat stroke index. For example, it may be configured to determine the possibility of heat stroke based only on the bathroom temperature, that is, if the bathroom temperature is equal to or higher than the predetermined temperature Ta, it may be determined that there is a possibility of heat stroke. In this case, the predetermined temperature Ta does not necessarily have to be a constant value, and may be changed according to, for example, humidity. Further, unlike this, for example, when the outside air temperature is high and the bathroom temperature is likely to rise in a short time, the predetermined temperature Ta may be lowered, and the temperature may be changed according to the outside air temperature. The criteria for determining whether or not there is a possibility of heat stroke may be appropriately changed by the user in consideration of the degree of health of the user and the like.

In the above-described embodiment, when the bather may suffer from heat stroke, hot water is supplied from the hot water supply device to the bathtub, unheated air is blown from the bathroom dryer, and mist of unheated water from the mist ejection nozzle is used. The means of supply are adopted, but if at least one of these means is adopted, it is included in the technical scope of the present invention . Mist ejection nozzle is not limited to those attached to the bathroom dryer.

The human body detecting means is not limited to the pyroelectric type image sensor, and other types of sensors or an imaging camera can also be used.
The hot water supply device is not limited to the instantaneous type, and for example, a hot water storage type hot water supply device can also be used.
The bathroom referred to in the present invention is not limited to a normal bathroom in which a bathtub is installed, but is a concept including, for example, a shower room dedicated to a shower bath in which a bathtub is not installed. The washing place referred to in the present invention is an area other than the bathtub in the bathroom.
