The transmission unit 86 transmits information indicating the sleep state detected by the sleep sensor 85 to the control unit 90. In the following, information indicating the sleep state is also referred to as "sleep information". The sleep sensor 85 and the transmission unit 86 may be provided in the bedroom 80 as a device separate from the air conditioner 83. In such cases, the device including the sleep sensor 85 and the transmitter 86 is mounted, for example, on the wall or ceiling of the bedroom 80. The device including the sleep sensor 85 and the transmitter 86 may be a portable device.

The control unit 90 is connected to, for example, a water heater 2, an operating device 22, an air conditioner 23, an operating device 61, an air conditioner 62, an alarm 82, and an air conditioner 83. The control unit 90 may be provided anywhere in the building 1. The control unit 90 performs bidirectional communication with each connected device.

The control unit 90 has a function of controlling each connected device. The control unit 90 includes, for example, a storage unit 91, a calculation unit 92, a notification control unit 93, a correction unit 94, and an air conditioning control unit 95. The operation of this notification system will be described below with reference to FIGS. 3 to 5. FIG. 3 is a flowchart showing an operation example of the notification system according to the first embodiment. In the following, an example in which the biosensor 27 and the biosensor 67 detect the human skin temperature will be described.

In the control unit 90, it is determined whether or not the skin temperature information is input from the biosensor 67 provided in the living room 60 (S101). For example, when resident A is in the living room 60 before taking a bath, the skin temperature of resident A is detected by the biosensor 67. If the biosensor 67 is attached to the air conditioner 62, the skin temperature information detected by the biosensor 67 is input to the control unit 90 via the air conditioner 62.

If it is determined to be Yes in S101, the control unit 90 stores the skin temperature detected by the biosensor 67 in the storage unit 91 as the normal skin temperature of the resident A (S102). The normal skin temperature is the temperature of the skin in normal life without bathing or exercising. In the following, the normal skin temperature stored in the storage unit 91 is also referred to as a “reference value”.

Further, in the control unit 90, it is determined whether or not the skin temperature information is input from the biosensor 27 provided in the bathroom 20 (S103). For example, when the resident A enters the bathtub 21 in the bathroom 20, the skin temperature of the resident A is detected by the biosensor 27. If the biosensor 27 is attached to the air conditioner 23, the skin temperature information detected by the biosensor 27 is input to the control unit 90 via the air conditioner 23.

If it is determined to be Yes in S103, the control unit 90 stores the skin temperature detected by the biological sensor 27 in the storage unit 91 as the skin temperature when the resident A takes a bath. Then, if it is determined to be Yes in S103, the calculation unit 92 calculates the first time for recommending the end of bathing and the second time for recommending bedtime (S104).

FIG. 4 is a diagram showing changes in skin temperature and core body temperature during and after bathing. Sleep quality is known to be affected by core body temperature. Therefore, in the example shown in this embodiment, the physical quantity of the person related to the core body temperature is detected by the biological sensor 27. The physical quantity related to the core body temperature means a physical quantity that is affected by a change in the core body temperature, or a physical quantity that affects the core body temperature by the change. Skin temperature is an example of a physical quantity associated with core body temperature. Heart rate, respiratory rate, and blood pressure are other examples of physical quantities associated with core body temperature.

In order to obtain good quality sleep, it is preferable to raise the skin temperature by bathing to promote heat dissipation, and to go to bed when the core body temperature after bathing is low. As a result, you can sleep deeper and recover from fatigue. In FIG. 4, the curve Ts shows an example of changes in human skin temperature during and after bathing. Curve Td1 shows an example of changes in a person's core body temperature during and after bathing.

As shown in FIG. 4, the human skin temperature Ts rises when bathing is started, that is, when entering the bathtub 21 in which water of about 40 ° C. is stored. The rate of increase in skin temperature Ts during bathing decreases over time. Then, when the bathing is finished, that is, when the bathtub 21 is exited, the skin temperature Ts decreases. The skin temperature Ts, which has begun to decrease, gradually approaches a certain value.

As shown in FIG. 4, the human core body temperature Td1 rises when bathing is started. The rate of increase in core body temperature Td1 during bathing is smaller than the rate of increase in skin temperature Ts immediately after the start of bathing. In addition, the change in the rate of increase in core body temperature Td1 during bathing is smaller than the change in the rate of increase in skin temperature Ts. The core body temperature Td1 continues to rise even after the bath is finished. However, when the bathing is finished, heat dissipation from the skin surface starts, so that the core body temperature Td1 starts to decrease from a certain point. The rate of decrease in core body temperature Td1 after bathing is greater than the rate of decrease in skin temperature Ts after bathing. The core body temperature Td1 that has begun to decrease gradually approaches a certain value.

As mentioned above, in order to obtain good quality sleep, it is preferable to go to bed when the core body temperature after bathing is low. When the core body temperature changes as shown in the curve Td1, the time t1 is the recommended time to go to bed.

The core body temperature Td2 and the core body temperature Td3 show comparative examples with respect to the core body temperature Td1, respectively. The curve Td2 shows an example in which the period of increase in core body temperature due to bathing is long. The maximum value of core body temperature Td2 is higher than the maximum value of core body temperature Td1. Further, the time when the core body temperature Td2 starts to decrease after bathing is later than the time when the core body temperature Td1 starts to decrease. When the core body temperature changes as shown in the curve Td2, the time t2 is the recommended time to go to bed. However, if the maximum value of core body temperature becomes too high due to bathing, it takes time for the core body temperature to decrease, which is not preferable for obtaining good sleep.

The curve Td3 shows an example in which there is no increase in core body temperature due to bathing. Even without bathing, core body temperature rises in the evening and begins to fall at some point, as shown by curve Td3. As shown in FIG. 4, the rate of increase in core body temperature Td3 is smaller than the rate of increase in core body temperature Td1. Therefore, the rate of decrease in core body temperature Td3 is smaller than the rate of decrease in core body temperature Td1. When the core body temperature changes as shown in the curve Td3, the core body temperature decreases slowly, so that the sleep tends to be light.

In S104, the calculation unit 92 calculates the first time for recommending the end of bathing and the second time for recommending bedtime from the relationship between the skin temperature Ts and the core body temperature Td1 as shown in FIG. Specifically, the calculation unit 92 calculates the above based on the amount of change in the skin temperature from the reference value, the amount and temperature of the water in the bathtub 21, and the bathing time of the person whose skin temperature is detected by the biological sensor 27. I do.

The amount of change in the skin temperature from the reference value can be obtained from the value detected by the biological sensor 27 and the reference value stored in the storage unit 91. For example, the calculation unit 92 calculates the amount of change in skin temperature per unit time, that is, the rate of change, detected by the biological sensor 27 when bathing is started. The rate of change calculated by the calculation unit 92 is stored in the storage unit 91.

As a value indicating the amount of water in the bathtub 21, the value detected by the water amount detecting unit 4 is used. As a value indicating the amount of water in the bathtub 21, the value set from the operating device 22 may be used. When a sensor for measuring the amount of water in the bathtub 21 is provided, the measured value of the sensor may be used as a value indicating the amount of water. Further, as a value indicating the water temperature in the bathtub 21, the value detected by the water temperature detecting unit 5 is used. As a value indicating the water temperature in the bathtub 21, the value set from the operating device 22 may be used. When a sensor for measuring the water temperature in the bathtub 21 is provided, the measured value of the sensor may be used as a value indicating the water temperature.

The bathing time of the resident A can be obtained from, for example, the parameters detected by the biosensor 27. As another example, a sensor for detecting the water level in the bathtub 21 may be provided in the bathroom 20, and the bathing time may be obtained from the fluctuation of the detection value of the sensor.

The calculation unit 92 obtains an estimated value of the core body temperature based on the amount of change from the reference value of the skin temperature, the amount and temperature of the water in the bathtub 21, and the bathing time, and the first time and the second from the obtained estimated value. You may calculate the time. FIG. 5 is a diagram showing the relationship between core body temperature, water temperature, and bathing time. The core body temperature shown in FIG. 5 is an example. Core body temperature is also affected by the amount of water. In addition, there are individual differences in core body temperature. Therefore, in the example shown in this embodiment, the amount of change in the skin temperature from the reference value and the amount of water in the bathtub 21 are also adopted as parameters.

As shown in FIG. 5, the higher the water temperature at the time of bathing, the higher the core body temperature in a short time. The longer the bathing time, the higher the core body temperature even if the water temperature is low. For example, if the water temperature is 41 ° C. and the bathing time is 10 minutes, the core body temperature can be estimated to be 37.4 ° C. The data for obtaining the estimated value of the core body temperature as shown in FIG. 5 is stored in advance in the storage unit 91. The calculation unit 92 calculates an estimated value of the core body temperature using the data stored in the storage unit 91.

When the calculation unit 92 calculates the first time and the second time in S104, the notification control unit 93 notifies the calculated first time and second time from the operation device 22 (S105). In the example shown in this embodiment, the notification control unit 93 displays the first time on the display 25 as the time recommended for the end of bathing. The notification control unit 93 displays the second time on the display 25 as the time recommended for going to bed. As a result, information for obtaining a comfortable sleep can be transmitted in the bathroom 20.

After that, the control unit 90 determines whether or not the skin temperature information is input from the biosensor 67 provided in the living room 60 (S106). For example, when the resident A leaves the bathroom 20 and returns to the living room 60, the skin temperature of the resident A is detected by the biosensor 67. The skin temperature information detected by the biosensor 67 is input to the control unit 90.

For example, when the heating operation is performed by the air conditioner 62 in the living room 60, the rate of decrease in the skin temperature of the resident A becomes slow. The correction unit 94 corrects the second time calculated by the calculation unit 92 based on the amount of change from the reference value of the skin temperature detected by the biological sensor 67 (S107). For example, if the amount of change is larger than the predicted value, the correction unit 94 adds the correction time to the second time.

When the correction unit 94 corrects the second time in S107, the notification control unit 93 notifies the corrected second time from the operation device 61 (S108). In the example shown in the present embodiment, the notification control unit 93 displays the corrected second time on the display 65 as the time recommended for going to bed. As a result, the resident A can be notified of the recommended bedtime according to the situation after bathing.

Further, the control unit 90 determines whether or not the time information has been input from the input device 66 (S109). For example, the resident A can change the second time calculated by the calculation unit 92 or the second time corrected by the correction unit 94 to a desired time by inputting the time information from the input device 66. The time information input from the input device 66 is input to the control unit 90.

If it is determined to be Yes in S109, the air conditioning control unit 95 controls the air conditioner 62 according to the time information input from the input device 66 (S110). For example, when information indicating a time later than the second time calculated by the calculation unit 92 is input from the input device 66, the air conditioning control unit 95 adjusts the air in order to shift the time zone in which the core body temperature drops to the later time zone. The heating operation by the machine 62 is carried out. The air conditioning control unit 95 may control both the air conditioner 62 and the air conditioner 83 in S110.

Further, the control unit 90 determines whether or not the current time has reached the second time (S111). If it is determined to be Yes in S111, the notification control unit 93 notifies from the operation device 61 that the current time has reached the second time (S112). In the example shown in this embodiment, the notification control unit 93 displays on the display 65 that it is time to recommend going to bed. In S112, the notification control unit 93 may perform notification using only sound. In S112, the notification control unit 93 may notify from both the operating device 61 and the alarm 82 that the current time has reached the second time.

Further, the control unit 90 determines whether or not sleep information has been received (S113). For example, when the resident A falls asleep in the bedroom 80, the transmission unit 86 transmits the sleep information detected by the sleep sensor 85 to the control unit 90. If it is determined to be Yes in S113, the control unit 90 stores the sleep information received from the transmission unit 86 in the storage unit 91 (S114). The sleep information stored in the storage unit 91 is used, for example, when the calculation unit 92 calculates the first time and the second time from the next time onward. The physiological state of resident A when sleeping changes depending on the season, bedding, and the like. By using the actual sleep information detected by the sleep sensor 85, the first time and the second time can be corrected according to the actual physiological state of the resident A.

In the present embodiment, an example in which the control unit 90 controls each device has been described. This is just an example. For example, among the functions of the notification control unit 93, the function of controlling the display 25 may be provided by the operation device 22. Similarly, among the functions of the notification control unit 93, the function of controlling the display 65 may be provided by the operation device 61. Among the functions of the notification control unit 93, the function of controlling the alarm 82 may be provided by the alarm 82.
