The ventilator 2 in this embodiment corresponds to a type 1 ventilator that uses a fan for both air supply and exhaust. The ventilation means in the present disclosure is not limited to the first type ventilation device. For example, a second type ventilation device that uses a fan for supply and does not use a fan for exhaust may be used, or a fan is used for exhaust. , A third-class ventilation system that does not use a fan for air supply may be used. Also, for example, an air conditioner having a function of taking in outside air can be used as the ventilation means in the present disclosure. For example, it is possible to use a central air conditioner installed in a house as the ventilation means in the present disclosure. The ventilation means in the present disclosure may be configured to be able to take in the room.

Ventilator 2 in the present embodiment includes temperature sensor 12 . In the illustrated example, a temperature sensor 12 is arranged near the exhaust port 6 .

The surface temperature sensor 16 has, for example, an infrared sensor array in which a plurality of infrared sensors are arranged in a row, and an actuator that scans the room 90 by moving the infrared sensor array. The surface temperature sensor 16 can detect the surface temperature of objects to be detected such as human bodies and objects in the room 90 and map the temperature distribution. For example, the surface temperature sensor 16 can detect the surface temperature of the human body of the user 91 , the surface temperature of the bedding 93 , the surface temperature of the floor of the room 90 , and the surface temperature of the walls of the room 90 . The surface temperature sensor 16 periodically performs the operation of detecting the surface temperature and acquires temperature distribution data of the room 90 .

As shown in FIG. 2, the ventilator 2 further includes a ventilation control section 17 corresponding to control means and a communication section 18 corresponding to communication means. The ventilation control unit 17 controls the ventilation operation of the ventilation device 2 . The ventilation control unit 17 may have a timer function for managing the date and time.

The air conditioning control unit 20 controls the air conditioning operation of the air conditioner 14 . The air conditioning control unit 20 may have a timer function that manages the date and time. The communication unit 21 is, for example, a transmitter/receiver for wireless communication. Regarding the air conditioner 14, the configurations of the refrigerating cycle, the blower fan, and the like necessary for realizing the air conditioning operation are well known, and thus the illustration thereof is omitted in the present disclosure.

Data can be transmitted and received bidirectionally between the communication unit 18 of the ventilator 2 and the communication unit 21 of the air conditioner 14 . For example, information detected using the surface temperature sensor 16 may be transmitted from the communication section 21 to the communication section 18 . Further, bidirectional data transmission/reception may be possible between at least one of the communication unit 18 and the communication unit 21 and the smartphone 94 .

Here, human sleep will be explained. FIG. 3 is a diagram showing an example of changes in sleep state from when a person starts sleeping to when he or she wakes up. FIG. 3 shows the relationship between sleep depth, which indicates the depth of sleep, and body motion. The height of the vertical line indicating body movement indicates the magnitude of body movement. High vertical lines indicate large body movements.

As shown in FIG. 3, from when a person starts sleeping to when he or she next wakes up, the sleep shifts to deeper sleep in the order of sleep depth 1, 2, 3, and 4, and then sleep depth 3, The sleep cycle of 2, 1, transition to REM sleep is usually repeated in a period of about 90 minutes. In addition, the sleep time from the start of sleep until waking up is divided into a deep sleep segment, which is the first half of relatively deep sleep, and a light sleep segment, which is the latter half of relatively light sleep. can be considered separately. In the first half of sleep, since sleep is deep, the body is relatively insensitive to external stimuli such as air currents, temperature and humidity. On the other hand, in the latter half of sleep, the sleep becomes shallower, sleep depths 3 and 4 rarely occur, and the person is more likely to respond to external stimuli.

In general, the deeper you sleep, the less you move. Since the position of the user 91 can be identified from the temperature distribution data detected by the surface temperature sensor 16, body movements of the user 91 can be detected by comparing time-series temperature distribution data. As described above, body movements of the user 91 are associated with sleep states. By detecting the body motion of the user 91, it is possible to detect information about the sleep state such as sleep depth and sleep cycle.

For example, it may be as follows. The time when the surface temperature sensor 16 detects the body movement of the user 91 is stored. Then, the total number of body movements that have occurred in a certain period of time in the past is compared with a threshold value for determining the depth of sleep, and the depth of sleep is estimated from the comparison result. Further, the time width in which body movement is detected, that is, the time from the detection of body movement to the next detection of body movement may be compared with a threshold, and the depth of sleep may be estimated from the comparison result. . Alternatively, the state of sleep may be estimated by other methods.

The surface temperature sensor 16 functions as sleep state detection means for detecting the sleep state of the user 91, for example, as described above. Note that the sleep state detection means according to the present disclosure is not limited to the surface temperature sensor 16 . The sleep state detection means may use, for example, at least one of a radio wave sensor such as a Doppler sensor, an acceleration sensor of the smart phone 94, a visible light camera, an infrared camera, a thermography, and an ultrasonic radar. The sleep state detection means according to the present disclosure may consist of one device such as the surface temperature sensor 16, or may consist of a plurality of devices. Further, the sleep state detection means is not limited to the surface temperature sensor 16 provided in the air conditioner 14, and may be, for example, a sensor device installed in the ventilation device 2 or a device separate from the ventilation device 2 and the air conditioner 14. may

In the present embodiment, ventilation control unit 17, which is an example of control means, includes room temperature sensor 13, which is an example of room temperature detection means, temperature sensor 12, which is an example of ventilation temperature detection means, and surface sensor 12, which is an example of sleep state detection means. The ventilator 2 is controlled according to the detection result of the temperature sensor 16 . Then, the ventilation control unit 17 shifts the sleep state of the user 91 from the deep sleep interval in the first half of sleep to the light sleep interval in the latter half of sleep, which is a lighter sleep interval than the deep sleep interval. Determine time. Further, the ventilation control unit 17 controls the ventilation device 2 so that the temperature of the room 90 rises to the wake-up preset temperature from the transition time to the wake-up time of the user 91 . According to the present embodiment, outside air can be taken in while the user 91 is in a light sleep state, and the temperature can be raised to the wake-up set temperature in time with the wake-up time. As a result, for example, it is possible to obtain effects such as prevention of coldness in bed and suppression of awakening due to rapid temperature changes or airflow changes in deep sleep intervals. According to the present embodiment, it is possible to provide the ventilation air-conditioning system 1 that is advantageous for the user 91 to get good quality sleep.

FIG. 4 is a flow chart showing an operation example of the ventilation air-conditioning system 1 according to the first embodiment. FIG. 5 is a graph showing an example of changes over time in room temperature during operation of the ventilation air-conditioning system 1 according to Embodiment 1. In FIG. A specific example of the operation of the ventilation air-conditioning system 1 will be described below with reference to FIGS. 4 and 5. FIG.

After the user 91 goes to bed, air conditioning may be performed so that the room temperature is slightly lower than the set temperature for waking up so that the user 91 can quickly fall asleep. For example, the air conditioner 14 may cool the room 90 in advance. The preset temperature when waking up and the preset temperature when going to bed can be arbitrarily set by the user 91, for example.

When the user 91 goes to bed 92, the operation of the ventilation air-conditioning system 1 is started. When the user 91 goes to bed, the sleep state of the user 91 is detected by the sleep state detecting means such as the surface temperature sensor 16 . The ventilation control unit 17 determines whether the sleep state of the user 91 has changed from the deep sleep period to the light sleep period based on the detection result of the sleep state detection means. Also, the transition time, which is the transition time, is determined (step S1).

In general, the deep sleep segment of a person often consists of two sleep cycles consisting of REM sleep and non-REM sleep. Therefore, for example, when the sleep state detecting means detects that two sleep cycles consisting of REM sleep and non-REM sleep have elapsed after the user 91 fell asleep, the ventilation control unit 17 changes the sleep state of the user 91 into a deep sleep interval. It may be determined that the state has transitioned from a certain state to a state in the light sleep interval. It should be noted that the determination of sleep segment transition is not limited to this. For example, the deep sleep interval may be set as one sleep cycle including REM sleep and non-REM sleep, or otherwise.

When the ventilation control unit 17 determines that the sleep state has transitioned to the deep sleep interval, it calculates the rate of temperature increase (step S2). The rate of temperature increase is calculated as "(set temperature at wake-up - room temperature at transition time)/(wake-up time - transition time)". By performing air conditioning at this rate of temperature increase, the room temperature at the time of waking up can be set to the set temperature at the time of waking up.

The ventilation control unit 17 determines the details of the control of the ventilation device 2 according to the calculated rate of temperature increase. For example, the ventilation control unit 17 sets the ventilation volume of the ventilator 2 . Further, the ventilation control unit 17 may set whether or not heat exchange is performed by the heat exchange element 5 (step S3). The ventilation control unit 17 controls the ventilator 2 according to the determined control details (step S4). As shown in FIG. 5, if the wake-up time is time 1, the temperature rise rate is 1; if the wake-up time is time 2, the temperature rise rate is 2; if the wake-up time is time 3, the temperature rise rate is 3; If the wake-up time is time 4, ventilation is performed at a temperature rise rate of 4. Note that the wake-up time may be arbitrarily set by the user, or may be automatically set based on the detection result of the past sleep state detection means.

FIG. 6 is a diagram showing the relationship between outside air temperature and ventilation amount. FIG. 7 is a table for explaining an example of controlling the amount of ventilation and the presence or absence of heat exchange. As shown in Figure 6, there is a difference in room temperature rise due to intake of outside air between a general house and a highly insulated house. need. In addition, as shown in FIG. 6, the amount of ventilation required to achieve the same rate of temperature increase also changes depending on the presence or absence of heat exchange. Therefore, as shown in the control table of FIG. 7, it is preferable to set the amount of ventilation according to the insulation properties of the house and the presence or absence of heat exchange. The ventilation and air-conditioning system according to the present embodiment is configured to be able to perform different controls according to the insulation properties of the house in which the ventilation device 2 is installed.

In the light sleep interval, the user 91 tends to be sensitive to environmental changes. Therefore, it is desirable to raise the temperature of the room 90 so as to gently change the temperature so as not to disturb the sleep of the user 91 in the light sleep section. Therefore, as shown in FIG. 7, when there are a plurality of combinations of ventilation volume control and heat exchange control that can raise the room temperature to the wake-up set temperature from the transition time to the wake-up time, , priority may be given to controlling the combination in which heat exchange takes place. According to this example, the temperature difference between the room temperature and the airflow flowing into the room 90 is reduced, and it is possible to suppress the awakening of the user 91 who is in the light sleep period.

Also, FIG. 8 is a table for explaining another example of control of the amount of ventilation and the presence or absence of heat exchange. In the light sleep section, it is preferable to set the noise value due to the operation of the ventilator 2 to a threshold value or less so as not to disturb the sleep of the user 91 . Therefore, as shown in FIG. 8, when there are a plurality of combinations of ventilation volume control and heat exchange control that can raise the room temperature to the wake-up set temperature from the transition time to the wake-up time, , the combination in which the noise value is equal to or less than the threshold value may be prioritized. For example, if heat exchange causes the required ventilation volume to become too large, control is performed to reduce the ventilation volume without heat exchange. According to this example, it is possible to suppress awakening of the user 91 due to noise.

After controlling the ventilator 2 in step S4, the ventilation control unit 17 determines whether the current time has reached the wake-up time (step S5). If it is not the wake-up time, it is determined whether the room temperature has reached the wake-up set temperature (step S6). Here, if the room temperature has reached the wake-up set temperature, the control result is recorded as actual temperature increase rate>calculated temperature increase rate, and the ventilation operation is stopped (step S7). After step S7, the process of step S5 is performed again. Even if the room temperature has not reached the wake-up set temperature in step S6, the process of step S5 is performed again.

If it is the wake-up time in step S5, it is determined whether the room temperature has reached the wake-up set temperature (step S8). If the room temperature has not reached the wake-up set temperature, the control result is recorded as actual temperature increase rate<calculated temperature increase rate (step S9). If the room temperature reaches the wake-up set temperature in step S8, it means that appropriate control has been performed, and the result of the control is recorded as the actual temperature increase rate=calculated temperature increase rate (step S10). After steps S9 and S10, the ventilation operation by the ventilator 2 is stopped (step S11), and the operation by the ventilation air conditioning system 1 ends. The control results recorded in steps S7, S9, and S10 may be referred to when determining the details of control in step S3 when the ventilation air-conditioning system is operated next time. The ventilation and air-conditioning system 1 learns the previous control result by repeatedly operating, and can operate with higher precision.
