Description

    The present invention relates to a sleep environment control system, and particularly relates to air conditioning measures in a sleep space.

    Conventionally, in the sleeping space, the comfort of the air-conditioning target person who is in the sleeping state is improved, and it is the lowest in the head side of the human body and gradually increases as it goes to the leg side, so-called `` head cold foot fever '' A suitable air conditioning control method has been studied (see, for example, Patent Document 1).

The sleeping capsule of Patent Document 1 has a head-side inflow / outflow portion and a leg-side inflow / outflow portion provided with an air outlet for supplying conditioned air and an inlet for sucking room air, respectively, on the head side and the leg side. The air conditioning is controlled such that the temperature of the conditioned air supplied from the leg-side inflow / outflow portion is higher than the temperature of the conditioned air supplied from the head-side inflow / outflow portion. Thereby, a temperature distribution of “head cold foot heat” suitable for the comfort of each part of the human body is formed, and the comfort of the air-conditioning subject in the sleeping state is improved.

    However, in the above-described conventional sleeping capsule, air conditioning control of “head cold foot heat” suitable for the comfort of each part of the air-conditioning subject who is in the sleeping state is performed, but is always kept at a predetermined constant temperature. In addition, air conditioning control suitable for body temperature changes of air conditioning subjects has not been performed. Therefore, when the temperature change of the air conditioning subject is disturbed for some reason, the air conditioning subject has a problem that it is difficult to obtain deep sleep and comfortable awakening.

    The present invention has been made in view of such points, and the object of the present invention is to maintain the body temperature of the air-conditioning subject during sleep while maintaining the “head cold foot heat” of the air-conditioning subject who is sleeping in the sleep space. It is to provide a sleep environment control system that is an air conditioner corresponding to a change.

    The present invention changes the air temperature based on the body temperature change of the air conditioning subject. In other words, the body temperature during sleep of the human body changes to a so-called V-shape in which it decreases from the time of sleep to the middle of sleep and increases from a predetermined time before waking up. This is because from the time of falling asleep to the middle of sleep, the body temperature decreases because the brain heated up by daytime activity cools down and rests, and the body temperature is suitable for getting a comfortable awakening before waking up. It is to rise. And, as the degree of decrease in body temperature after sleeping is larger, the brain is sufficiently cooled down, so that sleep is deeper and the effect of recovery from fatigue is also increased.

    Therefore, when the body temperature change and the air temperature change of the air-conditioning subject who is in the sleeping state are examined, it becomes as shown in FIG. FIG. 13A shows a change in temperature in the sleeping room, and FIG. 13B shows a change in rectal temperature of the air-conditioning subject who is in the sleeping state. As shown in FIG. 13, a human is a constant temperature animal, but the body temperature during sleep is easily affected by the environmental temperature, and the environmental temperature in the sleeping room is constant as indicated by 170 in FIG. 13 (a). If there is, the body temperature of the air-conditioning subject becomes a smooth temperature change as indicated by 180 in FIG. However, if the environmental temperature in the sleeping room is controlled to be V-shaped as indicated by 171 in FIG. 13A, the body temperature of the air-conditioning subject also changes to V-shape as indicated by 181 in FIG. It becomes possible to lead to. As a result, the comfort of the air-conditioning subject during sleep is improved.

That is, the temperature control means (102) controls the thermoelectric element (41) of the head-side air conditioning passage (36) communicating with the head-side air circulation section (60), and the head-side air conditioning passage (36) Adjust the air flow through to 26 ° C, 4 ° C lower than 30 ° C.

    Next, the sleep time T0 of the air conditioning subject (100) is measured by the sleep depth measuring means (101) of the controller (12). The temperature control means (102) sets the initial set temperature of the leg-side conditioned air (71W) from a sleep time T0 until a predetermined time T1 after a predetermined period Δt1 determined and set in advance by the air conditioning subject (100). Control is performed so as to maintain 30 ° C. and the initial set temperature 26 ° C. of the head-side conditioned air (61 W). That is, in the early sleep period from the sleep time T0 to the predetermined time T1, “head cold foot heat” due to a constant temperature of 30 ° C. on the leg side and 26 ° C. on the head side is maintained, and the air-conditioning subject (100) is guided to a sleep state.

    Subsequently, the temperature control means (102) shows the characteristic line 120 in FIG. 6 while keeping the set temperature of the head-side conditioned air (61 W) constant at 26 ° C., as indicated by the characteristic line 121 in FIG. As shown, the heat exchange member (40) of the leg side air conditioner (30R) is controlled so that the temperature of the leg side conditioned air (71W) gradually decreases from the predetermined time T1 and reaches 28 ° C. at the predetermined time T2. . That is, the temperature control means (102) controls the thermoelectric element (41) of the leg-side air conditioning passage (36) communicating with the leg-side air circulation section (70), and the leg-side air conditioning passage (36) The passing air temperature is adjusted to gradually decrease from 30 ° C. to 28 ° C. from a predetermined time T1 to a predetermined time T2 before a predetermined reference time during sleep. Since the temperature of the leg-side conditioned air (71 W) decreases, the body temperature of the air conditioning target person (100) is induced to decrease from the early sleep stage to the middle sleep stage, and the air conditioning target person (100) is in deep sleep (hereinafter, deep sleep) To the state).

    The predetermined period T2 is automatically determined based on the sleep depth of the air conditioning target person (100). Therefore, this determination operation will be described. FIG. 7A conceptually shows changes in sleep depth with respect to time, and FIG. 7B conceptually shows changes in body temperature.

    A curve (201) shown in FIG. 7A represents the sleep depth, and sleep becomes deeper in the order of sleep depths 1, 2, 3, and 4. The depth of sleep is the deepest extremum (202) that deepens after falling asleep and reaches sleep stage 4. Thereafter, the sleep depth gradually decreases, and the peak of REM sleep and the extreme value that deepens sleep are alternately repeated. In general, the sleep depth gradually becomes shallower as sleep time passes, resulting in arousal. And if the sleep depth passes the state of deep sleep that appears near the second extreme value (203), the deep sleep state becomes difficult to appear, and deepening the second extreme value (203) as deep as possible It is desirable to obtain efficiently. Considering the change in body temperature shown in FIG. 7B, in order to make the second extreme value (203) as deep as possible, the body temperature is monotonous until the sleep depth reaches at least the second extreme value (203). It only has to be lowered. That is, the predetermined time T2 is set after the second extreme value (203).

    In order to further increase the time of the second deep sleep state, it is preferable to decrease the body temperature monotonously until the second deep sleep state is removed. Specifically, after obtaining the second extreme value (203) of the sleep depth from the sleep time T0, the time from the time point (204) of the sleep depth 3 to the time point (205) of the sleep depth 2 By monotonously decreasing the temperature of the leg-side conditioned air (71 W), the second deep sleep state time can be lengthened. That is, the predetermined time T2 when the set temperature of the leg-side conditioned air (71 W) reaches 28 ° C. is after the second extreme value (203) is obtained, and the sleep depth 2 from the time point (204) of the sleep depth 3 It is preferable that it is a time until it shifts to a time (205). In the present embodiment, the predetermined time T2 is set after the second extreme value (203) is obtained and before the transition from the time point (204) at the sleep depth 3 to the time point (205) at the sleep depth 2. . Thereby, since the state of the 2nd deep sleep can be lengthened, the ratio of the deep sleep in the total sleep time also increases.

    Thereafter, as shown in FIG. 6, the temperature control means (102) is configured to set the leg-side conditioned air (71W) set temperature 28 ° C. and the head-side conditioned air (61W) set temperature from the predetermined time T2 to the predetermined time T3. The heat exchange member (40) of the head side air conditioner (30F) and the leg side air conditioner (30R) is controlled so that 26 ° C. is kept constant.

    Next, the temperature control means (102) causes the temperature of the leg-side conditioned air (71W) to gradually increase from a predetermined time T3 after a predetermined reference time during sleep and reach 29 ° C. at a scheduled wake-up time T4. In addition, the heat exchange member (40) of the leg-side air conditioner (30R) is controlled. That is, the temperature control means (102) controls the thermoelectric element (41) of the leg-side air conditioning passage (36) communicating with the leg-side air circulation section (70), and the leg-side air conditioning passage (36) The passing air temperature is adjusted so as to gradually increase from 28 ° C. to 29 ° C. from a predetermined time T3 to a scheduled wake-up time T4. In addition, the temperature control means (102) heats the head-side air conditioner (30F) so that the temperature of the head-side conditioned air (61W) gradually increases from the predetermined time T3 and reaches 27 ° C. at the scheduled wake-up time T4. The replacement member (40) is controlled. That is, the temperature control means (102) controls the thermoelectric element (41) of the head-side air conditioning passage (36) communicating with the head-side air circulation section (60), and the head-side air conditioning passage (36) The passing air temperature is adjusted so as to gradually increase from 26 ° C. to 27 ° C. from a predetermined time T3 to a scheduled wake-up time T4. Since the temperature of the conditioned air on both the leg side and the head side (71W, 61W) rises, the body temperature of the air-conditioning target person (100) also rises, and the air-conditioning target person (100) wakes up comfortably at the scheduled wake-up time T4. Obtainable.

    The predetermined period T3 is automatically determined based on the relationship between the body temperature change with respect to the environmental temperature shown in FIG. 8A and the change in the sleep depth with respect to the time shown in FIG.

    As shown in FIG. 8A, generally, when the environmental temperature rises at time ts, the body temperature of the human body does not start to increase simultaneously with the increase in the environmental temperature, as shown in FIG. There is a relationship that body temperature rise starts at time tp, which is delayed by a predetermined period Δt from the start of temperature rise. The predetermined period Δt is measured in advance, and the predetermined period Δt depends on the delay in body temperature change due to the heat capacity of the human body and the delay due to bedding and clothes, but by measuring multiple times, the bedding and clothes due to the difference in season can be measured. It is possible to reduce the influence of the difference. Then, the predetermined period Δt is stored in advance in the storage unit.

    Next, the sleep depth measuring means (101) of the controller (12), as shown in FIG. 8 (b), T (j) time points (301) of the j-th and (j + 1) -th REM sleep after sleep. ), T (j + 1) time (302) is detected (j ≧ 2). A period of REM sleep immediately before the scheduled wake-up time T4 is obtained by multiplying the interval from the T (j) time point (301) to the T (j + 1) time point (302) by n times (n is a positive integer). The T (j + n) time point (303) added to the (j + 1) time point (302) is determined. In FIG. 8A, a period is used in which the interval from the time T (j) (301) to the time T (j + 1) (302) is doubled.

    In order to obtain a comfortable awakening at the scheduled wake-up time T4, the body temperature of the air-conditioning subject (100) starts to rise at least at the T (j + n) time (303) of the REM sleep immediately before the scheduled wake-up time T4. preferable. Then, considering the relationship of the body temperature change with respect to the environmental temperature, in order to increase the body temperature of the air conditioning subject (100) from the T (j + n) time point (303), a predetermined period Δt before the T (j + n) time point (303). The temperature of the sleeping room (11) needs to rise. In addition, the temperature of the sleeping room is determined for a predetermined period from the T (j + n) time (303), since the awakening becomes more comfortable when the temperature rise starts slightly before the T (j + n) time (303) of the REM sleep. It only needs to rise before Δ (t + α). That is, the predetermined time T3 is determined to be a predetermined time Δ (t + α) earlier than the T (j + n) time (303), which is the time of REM sleep immediately before the scheduled wake-up time T4.

    Then, after scheduled wake-up time T4, the temperature control means (103) of the controller (12) performs heat exchange of the leg-side air conditioner (30R) so that the temperature of the leg-side conditioned air (71W) becomes the set temperature 30 ° C. The member (40) is controlled, and the heat exchange member (40) of the head-side air conditioner (30F) is controlled so that the temperature of the head-side conditioned air (61W) becomes a set temperature of 28 ° C. Since the temperature of the leg side and head side conditioned air (71W, 61W) rises at the scheduled wake-up time T4, if the air-conditioning target person (100) cannot wake up at the scheduled wake-up time T4 or at the scheduled wake-up time T4 Even if the awakening is not comfortable, the air-conditioning subject (100) can obtain a comfortable awakening.

    On the other hand, in the case of heating operation, only the leg side air conditioner (30R) is driven, and the temperature control means (102) sets the temperature of the leg side conditioned air (71W) to the initial setting from bedtime to a predetermined time T1. The heat exchange member (40) of the leg-side air conditioner (30R) is controlled so that the temperature is 30 ° C., and the temperature distribution of the “head cold foot heat” suitable for the optimal temperature for each part of the human body is formed. To control. Then, after the predetermined time T1, the heat exchange member (41) of the leg-side air conditioner (30R) is controlled so that the temperature of the leg-side conditioned air (71W) changes in the same manner as during the cooling operation. That is, the temperature control means (102) gradually decreases the temperature of the leg-side conditioned air (71W) from 30 ° C. to 28 ° C. from the predetermined time T1 to the predetermined time T2, and from the predetermined time T2 to the predetermined time T3. After maintaining at a constant 28 ° C., the leg-side air conditioner (30R) is controlled so as to gradually rise from a predetermined time T3 so as to reach 29 ° C. at a scheduled wake-up time T4. And the said temperature control means (102) controls a leg side air conditioner (30R) so that it may become a fixed temperature of 30 degreeC after the wake-up scheduled time T4.

    By the control of the controller (12), a temperature distribution of “head cold foot heat” suitable for the comfort of each part of the human body is formed, and the body temperature change based on the sleep depth of the human body is led to a V shape. be able to. Then, the air conditioning target person (100) can obtain deep sleep and comfortable awakening.

-Effect of Embodiment 1-
As described above, according to the present embodiment, in the sleeping room (11), the period from the bedtime of the air-conditioning target person (100) to the predetermined time T1 in the early sleep period is the initial setting of the leg-side conditioned air (71W). Because the amount of heat exchange between the blood and the outside air, which is 30 ° C and the initial setting temperature of the head-side conditioned air (61W), 26 ° C, is large, and it is kept under the optimal temperature conditions for the comfort of each part of the human body. The air-conditioning target person (100) is guided to a sleep state.

    In addition, at the predetermined time T2 determined by the sleep depth measuring means (101) from the predetermined time T1 in the early stage of sleep, the leg-side conditioned air (71W) is maintained while the set temperature of the head-side conditioned air (61W) is maintained at 26 ° C. ) Is lowered from 30 ° C. to 28 ° C., the body temperature of the air-conditioning subject (100) can be lowered over the middle of sleep. Then, by setting the predetermined time T2 as the time point after the second extreme value (203) is obtained and the sleep depth 3 (204) is shifted to the sleep depth 2 (205), the second deep sleep The state can be lengthened, and as a result, the accumulated time of deep sleep can be increased in a short time.

    In addition, before the scheduled wake-up time T4, the set temperature of the leg-side conditioned air (71W) is 28 ° C. from the predetermined time T3 determined by the relationship between the body temperature change with respect to the environmental temperature of the air conditioning subject (100) and the sleep depth. Since the set temperature of the head side conditioned air (61 W) rises from 26 ° C. to 27 ° C., the body temperature of the air conditioning target person (100) also rises and the air conditioning target person (100) is comfortable. You can get awakening.

    Then, after the scheduled wake-up time T4, the set temperature of the leg-side conditioned air (71W) rises to the initial set temperature 30 ° C at bedtime, and the set temperature of the head-side conditioned air (61W) rises to 28 ° C. Even if the air conditioning target person (100) cannot wake up at the scheduled wake-up time T4 or the wake-up at the scheduled wake-up time T4 is not comfortable, the body temperature further rises and a comfortable wake-up can be induced.

    In this way, the set temperature of both conditioned air (71W, 61W) is adjusted to the sleep depth while maintaining the set temperature of the leg conditioned air (71W) to be higher than the set temperature of the head conditioned air (61W). By changing the temperature based on the temperature, a “head cold foot heat” suitable for the optimum temperature for each part of the human body is formed, and the temperature change of the air-conditioning subject (100) in the sleeping state is guided to a V shape. Can do. Then, the air conditioning target person (100) can obtain deep sleep and comfortable awakening.

<< Other Embodiments >>
The present invention may be configured as follows with respect to the above embodiment.

    In Embodiments 1 to 3 and Reference Examples 1 and 2, the predetermined time T2 and the predetermined time T3 are determined by measuring the sleep depth of the air-conditioning target person (100) as needed using the sleep depth measurement means (101). However, you may control by memorize | storing the sleep depth of the air conditioning object person (100) measured by the sleep depth measurement means (101) in a memory | storage part (103) previously. Also, the sleep control time (102) may be controlled by a timer or the like without using the sleep depth measuring means (101) at the time of sleep T0, the predetermined time T2, and the predetermined time T3.

    In Embodiments 1 and 2 and Reference Example 1, the predetermined time T3 is later than the predetermined time T2, but the predetermined time T2 and the predetermined time T3 may be the same time. That is, the set temperature on the leg side becomes the lowest point at the predetermined time T2, and the temperature rise may be started after maintaining a constant temperature for a while, or the temperature rise may be started immediately after reaching the lowest point. . The predetermined time T3 may be after the predetermined time T2.

    In Embodiments 1 and 2 and Reference Example 1, the predetermined time T1 is a time later than the sleep time T0, but the predetermined time T1 and the sleep time T0 may be the same time. In other words, by setting the predetermined time period ΔT1 during which the air-conditioning target person (100) keeps the “cold foot heat” at a constant temperature from the sleep time T0 as 0 hours, the temperature is gradually lowered from the sleep time T0 to the predetermined time T2.

    In Embodiments 1 to 3 and Reference Examples 1 and 2, the set temperature of the head-side conditioned air (61 W) and the leg-side conditioned air (71 W) is kept constant after the scheduled wake-up time T4. The temperature may be gradually increased from time T4. When the air conditioning target person (100) wakes up, the control of the controller (12) may be stopped by the operation box, or the control is automatically stopped after a predetermined time from the scheduled wakeup time T4. It may be set as follows.

    Further, the temperature difference between the leg-side conditioned air (71W) and the head-side conditioned air (61W) and the temperature difference between the leg-side conditioned air (71W) and the head-side conditioned air (61W) are the temperatures shown in the first to fifth embodiments.

    Moreover, as long as the temperature distribution of “head cold foot heat” is formed, the control behavior of the head-side conditioned air (61W) and the leg-side conditioned air (71W) in the first to fifth embodiments may be reversed. For example, in the second embodiment, when the control behavior of the head-side conditioned air (61W) and the leg-side conditioned air (71W) is reversed, the leg-side conditioned air (71W) is constant, and the head-side conditioned air (61W ) Changes as the set temperature of the head-side conditioned air (61 W) shown in the third embodiment. Also in this case, the temperature distribution of the “head cold foot heat” is formed, and the body temperature change of the air conditioning subject (100) can be led to a V shape.

    In the first embodiment, only the leg-side air conditioner (30R) is driven during the heating operation. In the cooling operation of the first embodiment and in the second, third, and reference examples 1 and 2, the head side and the leg side are driven. Both air conditioners (30F, 30R) are driven, but if the temperature distribution of “head cold foot heat” in the sleeping room (11) is formed and the temperature of the sleeping room (11) becomes a V-shaped change, during cooling operation In both heating and heating operations, only one of the head side air conditioner (30F) and leg side air conditioner (30R) may be driven, or both air conditioners (30F, 30R) may be driven. .

    Further, the control of the head side and leg side set temperatures in Embodiments 1 to 3 and Reference Examples 1 and 2 is a linear change as shown in FIGS. 6 and 9 to 12, but a gentle sine wave. It is also possible to control the change in general, or a combination thereof.

    The shape of the sleeping capsule covering member, the air conditioning unit, and the like are not limited to the configuration of the sleeping capsule (10). For example, the covering member may be a single-opening type or a double-opening type that rotates left and right instead of up and down. The heat exchange member (40) is not limited to the thermoelectric element (41), and may be an evaporator or a condenser of a vapor compression refrigeration cycle. Further, the sleeping room is not limited to the sleeping capsule, and may be an indoor space suitable for the air-conditioning target person (100) to sleep.
