As modified examples are also mentioned in the above description of the embodiment, the arrangement of each component of the air conditioning system according to the present disclosure is not limited to that shown in FIG. 1 . For example, living room 300 may be adjacent to dressing room 100 . The air conditioning system according to the present disclosure may include at least the dressing room air conditioner 110 among the dressing room air conditioner 110, the bathroom air conditioner 210, and the living room air conditioner 310.

Similarly, FIG. 2 only shows an example of the control system of the air conditioning system. The configuration of the control system of the air conditioning system according to the present disclosure is not limited to that shown in FIG. The configuration of the air conditioning system is not limited to a configuration in which operation is controlled by a single device such as control unit 500 . The air conditioning system may be configured such that operations are controlled by cooperation of a plurality of devices.

In the example shown in FIG. 2 , control unit 500 is provided outside dressing room air conditioner 110 , bathroom air conditioner 210 , water heater 221 and living room air conditioner 310 . The function of the control unit 500 may be provided in at least one of the dressing room air conditioner 110, the bathroom air conditioner 210, the water heater 221, and the living room air conditioner 310, for example.

Also, the dressing room air conditioner 110, the bathroom air conditioner 210, the water heater 221, and the living room air conditioner 310 may be connected by wire or wirelessly. The dressing room air conditioner 110, the bathroom air conditioner 210, the water heater 221, and the living room air conditioner 310 may communicate and cooperate with each other. The functions of the control unit 500 include, for example, a control device built into the dressing room air conditioner 110, a control device built into the bathroom air conditioner 210, a control device built into the water heater 221, and a control device built into the living room air conditioner 310. It may be realized by cooperation of control devices.

Next, determination by determination unit 503 and control by control unit 504 will be described in more detail. As described above, the determination unit 503 and the control unit 504 constitute an example of control means for controlling the changing room air conditioner 110 so as to suppress at least one of hot water chills and hot flashes. The determination unit 503 determines the state of the user in the dressing room after bathing. More specifically, the determining unit 503 determines whether the user in the dressing room after taking a bath is in a state in which there is a possibility of getting hot, or a state in which there is a possibility of getting cold after bathing. The determination unit 503 makes the above determination, for example, based on a specific algorithm stored as a program in the storage unit 502 .

When the determination unit 503 determines that the user in the dressing room after bathing is likely to be hot, the control unit 504 operates the dressing room air conditioner 110 to suppress hot flashes. Further, when the determination unit 503 determines that the user in the dressing room after taking a bath is likely to become cold after bathing, the control unit 504 operates the changing room air conditioner 110 to suppress the feeling of coldness after bathing. Let The control unit 504 controls the changing room air conditioner 110 based on, for example, a specific algorithm stored as a program in the storage unit 502 .

FIG. 4 is a diagram showing an example of determination by the determination unit 503 and control by the control unit 504. In FIG. In the embodiment shown in FIG. 4, the determination unit 503 determines whether the state of the user is the first state, the second state, or the third state. The first state and the second state are states in which a user who has been overheated by bathing may become hot after bathing. The second state is a state in which the user's whole body is cold at the feet, which are the end portions of the whole body. The third state is a state in which a user who has not sufficiently warmed up by bathing may feel cold after bathing.

As an example, determination of the state of the user in the dressing room after bathing is performed based on the difference in physical quantity before and after movement, as shown in FIG. This "physical quantity" means any one of skin temperature, heart rate and respiration rate. Any one of skin temperature, heart rate, and respiratory rate is an example of the first physical quantity. The “difference in physical quantity before and after movement” refers to the physical quantity of the person in the bathroom 200 immediately after taking a bath, the physical quantity of the person at the time the person leaves the bathroom 200 and moves to the dressing room 100, means the difference between That is, the “difference in physical quantity before and after movement” means the difference in physical quantity regarding a person before and after movement from bathroom 200 to dressing room 100 . In the following description, for the sake of brevity, this "difference in physical quantity before and after movement" may be simply referred to as "difference in physical quantity".

Specifically, the above difference in physical quantity is determined by the physical quantity detected by the biosensor 111 when the user is in the dressing room 100 after bathing, and by the biosensor 211 when the user is in the bathroom 200 immediately after bathing. It is calculated by subtracting the physical quantity

When the difference in physical quantity is a positive value equal to or greater than the threshold, the determining unit 503 determines that the user's state is the first state or the second state, as shown in FIG. This threshold is preset. The case where the difference in the physical quantity is a positive value equal to or greater than the threshold means the case where the physical quantity increases significantly compared to a preset reference before and after moving from the bathroom 200 to the dressing room 100 . .

Specifically, the case where the above-mentioned physical quantity significantly increases compared to a preset reference before and after moving from the bathroom 200 to the dressing room 100 is the skin temperature of the user who has moved from the bathroom 200 to the dressing room 100, This is the case when the heart rate, respiratory rate, etc., suddenly increase. In this case, it is assumed that the user will get hot after taking a bath.

When the determination unit 503 determines that the user is in the first state or the second state, the control unit 504 causes the changing room air conditioner 110 to perform cooling operation or air blowing operation. The dressing room air conditioner 110 lowers the body temperature of the user in the dressing room 100 after bathing by cooling or blowing air. This suppresses hot flashes of the user. In addition, by suppressing rapid sweating in the case of hot flashes, it is possible to prevent coldness in hot water due to cold sweat. In addition, lightheadedness due to sudden changes in body temperature is also suppressed.

Further, when the difference in the physical quantity is a positive value equal to or greater than the threshold and the temperature of the user's feet in the dressing room 100 is equal to or less than the preset threshold, the determination unit 503 determines that the state is the second state. judge. The temperature of the user's feet in the dressing room 100 is detected by the biosensor 111 .

When the determination unit 503 determines that the user is in the second state, the control unit 504 causes the dressing room air conditioner 110 to blow warm air toward the floor of the dressing room 100 . This improves the cooling of the user's feet. At this time, since the feet of the user are cold, it is preferable to avoid blowing air to the feet. When the determining unit 503 determines that the user is in the second state, the changing room air conditioner 110 performs, for example, a windbreak operation in which the user's feet are not directly exposed to the wind.

When the difference in physical quantity is a negative value equal to or less than the threshold, the determination unit 503 determines that the user's state is the third state, as shown in FIG. This threshold is preset. The case where the difference in the physical quantity is a negative value equal to or less than the threshold means the case where the physical quantity drops significantly compared to a preset reference before and after moving from the bathroom 200 to the dressing room 100 . .

When the above-mentioned physical quantity drops significantly compared to a preset reference before and after moving from the bathroom 200 to the dressing room 100, specifically, the skin temperature of the user who moves from the bathroom 200 to the dressing room 100, This is the case when the heart rate, respiration rate, etc., suddenly drop. In this case, it is highly probable that the user was not sufficiently warmed up by bathing. That is, it is assumed that the user will get cold after taking a bath.

When the determination unit 503 determines that the state of the user is the third state, the control unit 504 causes the changing room air conditioner 110 to perform the heating operation. The dressing room air conditioner 110 suppresses a decrease in the body temperature of the user in the dressing room 100 after taking a bath through the heating operation. The heating operation by the dressing room air conditioner 110 ends, for example, when the user's skin temperature, heart rate, respiration rate, etc. reach preset reference values. It should be noted that the heating operation by the dressing room air conditioner 110 is preferably a windbreak operation in which the user is not directly exposed to the wind. This suppresses the coldness felt by the user.

Note that the determination by the determining unit 503 may be performed based on the “rate of change in physical quantity per unit time” instead of the “difference in physical quantity”. For example, the determination unit 503 may determine that the state of the user is the first state or the second state when the change rate of the physical quantity per unit time is equal to or greater than the threshold. The determination unit 503 may determine that the state of the user is the third state when the change rate of the physical quantity per unit time is equal to or less than the threshold. Note that the determination unit 503 may determine the state of the user according to the combination of the physical quantity and the change rate of the physical quantity per unit time.

Further, the control unit 504 may control the living room air conditioner 310 in the same manner as the dressing room air conditioner 110, as shown in FIG. In other words, the control section 504 may link the living room air conditioner 310 with the dressing room air conditioner 110 . As a result, the user who has passed through the dressing room 100 and entered the living room 300 after taking a bath is prevented from feeling cold and hot.

Note that FIG. 4 merely shows an example of the operation of the air conditioning system according to the present disclosure. The operation of the air conditioning system according to the present disclosure is not limited to the example shown in FIG. For example, when the physical quantity detected by biosensor 111, biosensor 211, and biosensor 311 is blood pressure, determination and control different from the example shown in FIG. 4 are executed. The biosensor 111, the biosensor 211, and the biosensor 311 may detect a physical quantity different from the first physical quantity described above.

In the present disclosure, the determination of the state of the user in the dressing room 100 may be made based on the amount of change in physical quantity from the reference time until the time when the user is in the dressing room 100 after bathing. This amount of change is a parameter related to the state of the user after bathing, as described above. Moreover, as described above, the “reference time” is not limited to the time when the user is in bathroom 200 . A reference time point can be set as an arbitrary time point. An algorithm for judging the user's condition by the judging unit 503 is set based on the types of physical quantities detected by the biosensors 111, 211, and 311, the aforementioned reference time points, and the like. Also, the biosensor 111, the biosensor 211, and the biosensor 311 may detect, for example, multiple types of physical quantities. The biosensor 111, the biosensor 211, and the biosensor 311 may detect another physical quantity in addition to the first physical quantity described above.

Also, the determination of the state of the user in the dressing room 100 may be made, for example, based on the estimated core body temperature of the user. FIG. 5 is a diagram showing an example of the relationship between estimated core body temperature, hot water temperature, and bathing time. In addition, FIG. 5 shows an example to the last. The relationship between the estimated core body temperature, hot water temperature, and bathing time is affected by individual differences and environmental differences in bathroom 200 .

In general, the higher the sound of the hot water when a user takes a bath, the faster the user's core body temperature rises. In the example shown in FIG. 5, when the user takes a bath in hot water of 41° C. for 10 minutes or less, the estimated core body temperature of the user is calculated to be 37.5° C. or less. Calculation of the estimated value of the core body temperature is performed by the calculation unit 501, for example. A database such as that shown in FIG. 5 for calculating the estimated core body temperature is stored in advance in the storage unit 502, for example.

Arithmetic unit 501 calculates an estimated value of the core body temperature based on, for example, the hot water temperature and the amount of hot water, which are set values of hot water supply device 221 . The calculation unit 501 may calculate the estimated core body temperature based on the measured value of the hot water actually stored in the bathtub 220 . As an example, bathtub 220 may be provided with a sensor or the like for measuring the temperature and amount of hot water stored in bathtub 220 . Also, the bathing time is calculated by the computing unit 501 based on the parameters detected by the biosensor 211, for example.

As an example, the determination unit 503 determines that the state of the user is the first state or the second state when the estimated core body temperature is equal to or greater than a preset threshold. That is, when the estimated value of the core body temperature is equal to or greater than a preset threshold value, the determination unit 503 determines that the user is in a state where there is a possibility of hot flashes. Further, for example, when the estimated value of the core body temperature is equal to or less than a preset threshold value, the determination unit 503 determines that the state of the user is the third state. That is, when the estimated value of the core body temperature is equal to or less than a preset threshold value, the determination unit 503 determines that the user is likely to get cold after bathing.

Next, an operation example of the air conditioning system configured as shown in FIGS. 1 and 2 will be described with reference to a flow chart. 6 is a flowchart showing an operation example of the air conditioning system of Embodiment 1. FIG. Note that FIG. 6 merely shows an example of the operation of the air conditioning system. The operation of the air conditioning system according to the present disclosure is not limited to that shown in FIG.

The flowchart shown in FIG. 6 assumes that the user is in the living room 300 at the start. First, when the user is in the living room 300, the biosensor 311 detects the physical quantity of the user. Physical quantities detected by the biosensor 311 are stored in the storage unit 502 as normal parameters. The air conditioning system of the present embodiment thus acquires the user's parameters during normal times (step S101).

After step S101, it is determined whether or not the user has left the living room 300 and entered the dressing room 100 (step S102). The determination in S102 is performed by the determination unit 503 based on the physical quantity detected by the biosensor 311 and the biosensor 111, for example. Steps S101 and S102 are continued until the user leaves the living room 300 and enters the dressing room 100, as shown in FIG.

When a user enters the dressing room 100, the biosensor 111 detects the physical quantity of the user. A physical quantity detected by the biosensor 111 is stored in the storage unit 502 as a parameter of the user in the dressing room 100 . The calculation unit 501 calculates the difference between the user's parameter in the dressing room 100 and the user's parameter during normal times (step S103).

After the difference is calculated in step S103, it is determined whether or not the difference is within a predetermined range. This determination is a determination of whether or not an abnormality has occurred. For example, when the physical condition of the user in the dressing room 100 suddenly changes, the above difference is out of the predetermined range. The air conditioning system of the present embodiment thus determines whether or not there is an abnormality (step S104). The determination in step S104 is performed by the determination unit 503, for example. If it is determined in step S104 that an abnormality has occurred, the operation device 400, which is an example of a notification means, issues a notification (step S104a).

If it is determined in step S104 that no abnormality has occurred, it is determined whether or not the user has left the dressing room 100 and entered the bathroom 200 (step S105). The determination in S102 is performed by the determination unit 503 based on physical quantities detected by the biosensor 111 and the biosensor 211, for example. Steps S103 to S105 are continued until the user leaves the dressing room 100 and enters the bathroom 200, as shown in FIG.

When the user enters the bathroom 200, it is determined whether or not the user has entered the bathtub 220 (step S106). The determination in step S106 is performed by the determination unit 503 based on the physical quantity detected by the biosensor 211, for example. The determination in step S106 is made until the user enters the bathtub 220, that is, until the user starts bathing.

When the user starts bathing, the biosensor 211 detects the physical quantity of the user. The physical quantity detected by the biosensor 211 is stored in the storage unit 502 as a parameter of the user during bathing. The calculation unit 501 calculates the difference between the user's parameters during bathing and the user's parameters during normal times (step S107).

When the above difference is calculated in step S107, it is determined whether or not this difference is within a prescribed range set in advance, as in step S104. This determination is a determination of whether or not an abnormality has occurred (step S108). The determination in step S108 is performed by the determination unit 503, for example. If it is determined in step S108 that an abnormality has occurred, the operation device 400, which is an example of the notification means, issues a notification (step S108a).

If it is determined in step S108 that no abnormality has occurred, it is determined whether or not the user has left the bathtub 220 (step S109). The determination in S109 is performed by the determination unit 503 based on the physical quantity detected by the biosensor 211, for example. The determination in step S106 is made until the user leaves the bathtub 220, that is, until the user takes a bath.

When the user leaves bathtub 220, the state of the user in bathroom 200 is determined (step S110). The determination in step S110 is performed by the determination unit 503 based on the physical quantity detected by the biosensor 211, for example.

For example, when the skin temperature, heart rate, and respiration rate of the user in bathroom 200 are higher than preset thresholds, determination unit 503 determines that the user is in a hot flash. For example, when the skin temperature, heart rate, and respiration rate of the user in the bathroom 200 are lower than preset thresholds, the determining unit 503 determines that the user is likely to get cold after bathing. do.

When it is determined that the user in the bathroom 200 is in a hot state, the control unit 504 causes the bathroom air conditioner 210 to blow air, for example. This suppresses hot flashes of the user. Further, when it is determined that the user in the bathroom 200 is likely to be cold after bathing, the control unit 504 causes the bathroom air conditioner 210 to perform heating operation, for example. This heating operation is preferably a windbreak operation. As a result, the user is prevented from feeling cold after bathing. As described above, in the present embodiment, bathroom air conditioner 210 is controlled according to the state of the user in bathroom 200 (step S111).

In step S111 described above, water may be discharged by hot water supply device 221, which is an example of a water discharging means. For example, the biosensor 211 may detect the temperature of the user's feet after taking a bath. Water heater 221 discharges cold water when the temperature at the user's feet is equal to or higher than a preset threshold. As a result, hot flashes of the user are more effectively suppressed. Moreover, the hot water supply device 221 discharges hot water when the temperature of the user's feet is equal to or lower than a preset threshold value. This prevents the feet of the user from getting cold.

After step S111, it is determined whether or not an abnormality has occurred (step S112), as in steps S104 and S108. The determination in step S112 is performed by the determination unit 503 based on, for example, the physical quantity detected by the biosensor 211 and a preset algorithm. For example, the determination unit 503 determines that an abnormality has occurred when the rate of change per unit time of the user's physical quantity during bathing is equal to or greater than a preset threshold value. If it is determined in step S112 that an abnormality has occurred, the operating device 400, which is an example of a notification means, issues a notification (step S112a).

If it is determined in step S112 that no abnormality has occurred, it is determined whether or not the user has left bathroom 200 (step S113). The determination in step S113 is performed by the determination unit 503 based on the physical quantity detected by the biosensor 211 and the biosensor 111, for example. Steps S110 to S113 are performed until the user leaves bathroom 200, as shown in FIG.

When the user leaves the bathroom 200 and enters the dressing room 100, the state of the user is determined (step S114). Further, the changing room air conditioner 110 is controlled based on the determination result in step S114 (step S115). The determination in step S114 and the control in step S115 are performed as shown in FIG. 4 as an example. This prevents the user from getting cold and hot flashes after taking a bath.

Note that the air conditioning system according to the present disclosure does not necessarily have to suppress both hot water and hot flashes. The air-conditioning system according to the present disclosure may be configured to be capable of suppressing at least one of hot springs and hot flashes after bathing. In step S115, the dressing room air conditioner 110 may operate to suppress at least one of hot water and hot flashes after bathing.

After step S115, it is determined whether or not an abnormality has occurred (step S116), as in step S112. The determination in step S116 is performed by the determination unit 503 based on, for example, the physical quantity detected by the biosensor 111 and a preset algorithm. If it is determined in step S116 that an abnormality has occurred, the operation device 400, which is an example of the notification means, issues a notification (step S116a).

If it is determined in step S116 that no abnormality has occurred, it is determined whether or not the user has entered the living room 300 (step S117). The determination in step S117 is performed by the determination unit 503 based on physical quantities detected by the biosensor 111 and the biosensor 311, for example. Steps S114 to S117 are performed until the user enters the living room 300, as shown in FIG.

When the user enters the living room 300, the state of the user in the living room 300 is determined (step S118). The determination in step S118 is performed by the determination unit 503 based on the physical quantity detected by the biosensor 311, for example. The determination in step S118 is performed in the same manner as in step S110, for example. Living room air conditioner 310 is controlled based on the determination result of step S118 (step S119). Incidentally, in step S119, the living room air conditioner 310 may be controlled to interlock with the dressing room air conditioner 110 as shown in FIG.

After step S119 described above, it is determined whether or not an abnormality has occurred (step S120), as in steps S112 and S116. The determination in step S120 is performed by the determination unit 503 based on, for example, the physical quantity detected by the biosensor 311 and a preset algorithm. If it is determined in step S120 that an abnormality has occurred, the operation device 400, which is an example of the notification means, issues a notification (step S120a).

As described above, according to the air conditioning system of the present embodiment, it is possible to suppress at least one of hot water chills and hot flashes after bathing. Also, it is possible to detect a user's abnormality and notify the user of this abnormality.
