Description

[Technical Field]

[0001] The present disclosure relates to a conditioning device. [Background technology]

[0002] There are adjustment devices that adjust disturbances in a subject's biological rhythm. The adjustment device disclosed in Patent Document 1 calculates the biological rhythm of the subject based on the subject's core body temperature. The adjustment device applies light stimulation to the subject so that the calculated biological rhythm approaches an adjustment target. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 5-3919 Summary of the Invention [Problem to be solved by the invention]

[0004] The adjustment device of Patent Document 1 applies light stimuli to a subject. However, this adjustment device does not take into consideration other methods for adjusting the subject's biological rhythm. Furthermore, the adjustment device of Patent Document 1 does not take into consideration adjusting the subject's life rhythm.

[0005] The present disclosure provides an adjustment device that can adjust the biological rhythm and life rhythm of a subject. [Means for solving the problem]

[0006] The first aspect is directed to an adjustment device, and includes a spray device (41) that supplies a substance having a stimulating or sedative effect to a target space (S) in which a subject (T) is present, and a control device (100) that controls the spraying operation of the spray device (41) based on the biological rhythm of the subject (T) and reference data that serves as a basis for the biological rhythm, and based on the life rhythm of the subject (T) and reference data that serves as a basis for the life rhythm.

[0007] In a first aspect, the control device (100) controls the spraying operation of the spray device (41) based on the biological rhythm of the subject (T) and reference data that serves as a reference for this biological rhythm. The spray device (41) sprays a substance having a stimulating or sedative effect into the target space (S) in which the subject (T) is present, thereby adjusting the biological rhythm of the subject (T).

[0008] Alternatively, the control device 100 controls the spraying operation of the spray device 41 based on the life rhythm of the subject T and reference data that serves as a reference for this life rhythm. The spray device 41 sprays a substance having a stimulating or sedative effect into the target space S in which the subject T is present, and thus can adjust the life rhythm of the subject T.

[0009] In the second aspect, in the first aspect, the control device (100) controls the spraying operation of the spray device (41) based on the biological rhythm of the subject (T) and the reference data.

[0010] In the second aspect, the control device (100) sprays a substance having an awakening or sedative effect into the target space (S) based on the biological rhythm of the subject (T) and reference data, thereby adjusting the biological rhythm of the subject (T).

[0011] In a third aspect, when the control device (100) determines that the phase of the biological rhythm of the subject (T) is out of phase with the reference data, the control device (100) controls the spraying operation of the spray device (41) so as to bring the phase of the biological rhythm of the subject (T) closer to the reference data.

[0012] In the third aspect, the spray device (41) sprays a substance having a stimulating or sedative effect into the target space (S) so that the phase of the biological rhythm of the subject (T) approaches the reference data.

[0013] In the fourth aspect, when the control device (100) determines that the phase of the biological rhythm of the subject (T) is shifted forward from the reference data in the third aspect, the control device (100) causes the spray device (41) to spray the substance having the awakening effect a predetermined time before the set sleep onset time of the subject (T).

[0014] In a fourth aspect, when the biological rhythm of the subject (T) is shifted forward relative to the reference data, the spray device (41) sprays a substance having a stimulating effect a predetermined time before the set sleep onset time. As a result, the subject (T) can be prevented from falling asleep before the sleep onset time. By delaying the sleep onset time of the subject (T), the biological rhythm of the subject (T) can be shifted backward, and can be brought closer to the reference data.

[0015] In the fifth aspect, when the control device (100) determines that the phase of the biological rhythm of the subject (T) is shifted later than the reference data in the third aspect, the control device (100) causes the spray device (41) to spray the substance having a sedative effect a predetermined time before the set sleep onset time of the subject (T).

[0016] In a fifth aspect, when the biological rhythm of the subject (T) is delayed relative to the reference data, the spray device (41) sprays a substance having a sedative effect a predetermined time before the set sleep onset time. As a result, the subject (T) can be encouraged to fall asleep at the sleep onset time. By advancing the sleep onset time of the subject (T), the biological rhythm of the subject (T) can be shifted forward, and can be brought closer to the reference data.

[0017] In the sixth aspect, when the control device (100) determines that the phase of the biological rhythm of the subject (T) is shifted later than the reference data in the third aspect, the control device (100) causes the spray device (41) to spray the substance having the awakening effect at a set wake-up time of the subject (T).

[0018] In a sixth aspect, when the biological rhythm of the subject (T) is delayed relative to the reference data, the spray device (41) sprays a substance having a stimulating effect at a set wake-up time. As a result, the subject (T) can be encouraged to wake up. By advancing the wake-up time of the subject (T), the biological rhythm of the subject (T) can be shifted later, and can be brought closer to the reference data.

[0019] In the seventh aspect, when the control device (100) determines that the amplitude of the biological rhythm of the subject (T) deviates from the reference data in the second aspect, the control device (100) causes the spray device (41) to spray the substance so as to bring the amplitude of the biological rhythm of the subject (T) closer to the reference data.

[0020] In the seventh aspect, the spray device (41) sprays a substance having a stimulating or sedative effect into the target space (S) so that the amplitude of the biological rhythm of the subject (T) approaches the reference data.

[0021] In the eighth aspect, when the control device (100) determines that the period of the biological rhythm of the subject (T) deviates from the reference value in the second aspect, the control device (100) causes the spray device (41) to spray the substance so as to bring the period of the biological rhythm of the subject (T) closer to the reference data.

[0022] In the eighth aspect, the spray device (41) sprays a substance having a stimulating or sedative effect into the target space (S) so that the cycle of the biological rhythm of the subject (T) approaches the reference data.

[0023] In a ninth aspect, in any one of the first to eighth aspects, the control device (100) is provided with an alarm unit (36) that notifies the subject (T) of an abnormality when it determines that the biological rhythm of the subject (T) is out of sync with the reference data or that the life rhythm of the subject (T) is out of sync with the reference data.

[0024] In the ninth aspect, the subject (T) can understand abnormalities in his / her own biological rhythms and life rhythms.

[0025] A tenth aspect is any one of the first to ninth aspects, wherein the control device (100) controls the spraying operation of the spray device (41) in accordance with the volume of the target space (S).

[0026] In the tenth aspect, the spray amount, spray time, substance concentration, etc. of the spray device (41) can be adjusted according to the volume of the target space (S).

[0027] In an eleventh aspect, in any one of the first to tenth aspects, the substance sprayed by the spray device (41) is a substance that is absorbed into the body of the subject to impart the stimulating or sedative effect to the subject (T) (excluding substances that are absorbed by nasal epithelial olfactory cells and act on the subject).

[0028] In the eleventh aspect, the substance sprayed from the spray device (41) is absorbed into the subject's body, thereby enhancing the stimulating and sedative effects imparted to the subject (T).

[0029] A twelfth aspect is any one of the first to eleventh aspects, wherein the substance having a stimulating effect includes caffeine, theobromine, ephedrine, catechin, or capsaicin, and the substance having a sedative effect includes theanine, glycine, serine, γ-aminobutyric acid (GABA), hastatoside, verbenaline, ornithine, crocin, or crocetin.

[0030] In a thirteenth aspect, in any one of the first to twelfth aspects, the control device (100) causes the spray device (41) to spray the substance having a sedative effect based on the biological rhythm of the subject (T) and the reference data, or based on the biological rhythm of the subject (T) and the reference data.

[0031] In the thirteenth aspect, the biological rhythm and life rhythm of the subject (T) can be adjusted by using a substance having a sedative effect. [Brief explanation of the drawings]

[0033] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below, and various modifications are possible within the scope of the technical concept of the present disclosure. Since the drawings are intended to conceptually explain the present disclosure, dimensions, ratios, or numbers may be exaggerated or simplified as necessary to facilitate understanding.

[0034] (1) Air conditioning system The adjustment device (40) of this embodiment is applied to an air conditioning system (1). The adjustment device (40) includes a spray device (41), a biosensor (50), and a control device (100). The adjustment device (40) sprays a useful substance onto a subject (T) present in an indoor space (S), which is a target space, based on the subject's (T) biorhythm, thereby adjusting the subject's (T) biorhythm. The subject (T) is, for example, an adult, but may also be a child or an elderly person.

[0035] (2) Air conditioning equipment As shown in FIGS. 1 and 2, the air conditioning system (1) has an air conditioner (10) that conditions an indoor space (S). The air conditioner (10) has an outdoor unit (20) and an indoor unit (30). The outdoor unit (20) and the indoor unit (30) are connected to each other via two connecting pipes (a liquid connecting pipe (11) and a gas connecting pipe (12)). This forms a refrigerant circuit (R) in the air conditioner (10). The refrigerant circuit (R) is filled with a refrigerant. The refrigerant circuit (R) performs a refrigeration cycle by circulating the refrigerant.

[0036] (2-1) Outdoor unit The outdoor unit (20) is disposed outdoors. The outdoor unit (20) has an outdoor fan (21). The outdoor unit (20) has, as elements connected to the refrigerant circuit (R), a compressor (22), an outdoor heat exchanger (23), a switching mechanism (24), and an expansion valve (25).

[0037] The compressor (22) compresses the drawn refrigerant and discharges the compressed refrigerant. The compressor (22) is an inverter type, and the rotation speed (operating frequency) of the compressor (22) is adjustable.

[0038] The outdoor heat exchanger (23) is a fin-and-tube type heat exchanger, and exchanges heat between the refrigerant flowing therethrough and the outdoor air transported by the outdoor fan (21).

[0039] The switching mechanism (24) is a four-way switching valve that changes the flow path of the refrigerant circuit (R) so as to switch the air conditioner (10) between cooling operation and heating operation. The switching mechanism (24) has a first port (P1), a second port (P2), a third port (P3), and a fourth port (P4). As shown by the solid lines in FIG. 2, in cooling operation, the first port (P1) and the fourth port (P4) communicate with each other, and the second port (P2) and the third port (P3) communicate with each other. As shown by the dashed lines in FIG. 2, in heating operation, the first port (P1) and the third port (P3) communicate with each other, and the second port (P2) and the fourth port (P4) communicate with each other.

[0040] The expansion valve (25) is disposed between the liquid side end of the outdoor heat exchanger (23) and the liquid side end of the indoor heat exchanger (32). The expansion valve (25) is an electronic expansion valve whose opening degree is adjustable.

[0041] (2-2) Indoor unit The indoor unit (30) is installed in the indoor space (S). The indoor unit (30) is, for example, a wall-mounted indoor air conditioner. The indoor unit (30) has a casing (31) and an indoor heat exchanger (32) and an indoor fan (33) housed in the casing (31).

[0042] An inlet (31a) and an outlet (31b) are formed in the casing (31). An air passage (34) is formed in the casing (31) from the inlet (31a) to the outlet (31b).

[0043] The indoor heat exchanger (32) is disposed in the air passage (34). The indoor heat exchanger (32) is a fin-and-tube type. The indoor heat exchanger (32) exchanges heat between the air transported by the indoor fan (33) and the refrigerant.

[0044] The indoor fan (33) is disposed in the air passage (34) downstream of the indoor heat exchanger (32). The indoor fan (33) is a cross-flow fan. The rotation speed of the indoor fan (33) is variable. In other words, the air volume of the indoor fan (33) is variable.

[0045] (2-3) Spraying device The indoor unit (30) has a spray device (41). The spray device (41) supplies a useful substance to the indoor space (S) where the subject (T) is present. The spray device (41) is disposed, for example, in the air passage (34) near the outlet (31b). The spray device (41) has a container (42), a supply path (43), and a discharge port (44). The container (42) stores an undiluted useful substance. The inlet end of the supply path (43) is connected to the container (42). The discharge port (44) is provided at the outlet end of the supply path (43). The spray device (41) has a driving source (45) for atomizing the useful substance. The driving source (45) is constituted by a pressure pump, an ultrasonic generator, an electrode for electrostatic spraying, or the like. In other words, the spray device (41) is constituted by a pressure type, an ultrasonic type, an electrostatic spray type, or the like.

[0046] The spray device (41) emits the useful substance in the form of a mist through the outlet (44) into the air passage (34). The indoor unit (30) supplies air containing the useful substance at a predetermined concentration through the air outlet (31b) to the target space (S).

[0047] (2-4) Useful substances The useful substance of this embodiment is a substance that has an awakening effect on the subject (T). The substance that has an awakening effect is a substance consisting of one of caffeine, theobromine, ephedrine, catechin, or capsaicin, or a mixture containing two or more of these. The useful substance that has an awakening effect imparts an awakening effect to the subject (T) when absorbed into the body of the subject (T). The useful substance is preferably one that is absorbed into the body through the subject's mouth. Furthermore, the useful substance preferably excludes substances that are absorbed through the nasal epithelial olfactory cells and act on the subject. The useful substance preferably excludes substances that stimulate the olfactory nerve of the subject (T). The useful substance is preferably an odorless substance, and is preferably a substance that does not affect the human sense of smell. The useful substance may also be a substance containing an odor component adjusted to a concentration at which humans cannot detect the odor.

[0048] (2-5) Remote Controller The air conditioner (10) has a remote controller (35). The remote controller (35) is a device that allows a subject (T) or the like to change the operation, temperature setting, etc. of the air conditioner (10). As shown in FIG. 3 , the remote controller (35) has a display unit (36) and an operation unit (37). The display unit (36) is an example of a notification unit. The display unit (36) is a display such as a liquid crystal screen. The operation unit (37) is composed of buttons or the like that are operated by a user. The display unit (36) and the operation unit (37) may be combined into a touch panel. When the biological rhythm of the subject (T) is out of sync, the display unit (36) notifies the subject (T) of an abnormality.

[0049] The subject (T) can set the sleep onset time and wake-up time by operating the operation unit (37) of the remote controller (35). The sleep onset time is the time when the subject (T) wants to fall asleep, and is set to, for example, a predetermined time in the night. The wake-up time is the time when the subject (T) wants to wake up, and is set to, for example, a predetermined time in the morning.

[0050] (3) Biosensor The biosensor (50) is an example of a detection unit for estimating the biorhythm of a subject (T) present in an indoor space (S). The biosensor (50) detects the skin temperature of the subject (T) present in the indoor space (S) as biometric information. The biosensor (50) is a wearable sensor attached to the subject (T). The biosensor (50) wirelessly outputs a signal indicating the detected skin temperature of the subject (T) to the control device (100). The biosensor (50) may output the detection signal to a wireless terminal such as a smartphone. In this case, the detection signal is output to the control device (100) via a network connected to the wireless terminal.

[0051] (4) Control device As shown in Fig. 3, the air conditioning system (1) includes a control device (100). The control device (100) includes a first control unit (C1), a second control unit (C2), and a third control unit (C3). The first control unit (C1) is provided in the outdoor unit (20). The second control unit (C2) is provided in the indoor unit (30). The third control unit (C3) is provided in the remote controller (35). The first control unit (C1), the second control unit (C2), and the third control unit (C3) each include a microcomputer and a memory device that stores software for operating the microcomputer.

[0052] The first control unit (C1) and the second control unit (C2) can transmit and receive signals bidirectionally via wire or wirelessly. The second control unit (C2) and the third control unit (C3) can transmit and receive signals bidirectionally via wire or wirelessly.

[0053] The control device (100) controls the operation of the air conditioner (10) and the various devices of the air conditioner (10). The control device (100) controls the spray device (41). The control device (100) has a memory unit (101) and a calculation unit (102). The memory unit (101) and the calculation unit (102) are provided in, for example, the second control unit (C2).

[0054] The storage unit (101) stores reference data that serves as a reference for the biological rhythm of the subject (T). Here, biological rhythms represent periodic changes in human biological phenomena. Among biological rhythms, rhythms with a period of approximately one day are called circadian rhythms. As shown in FIG. 4, the storage unit (101) stores information on waveforms that serve as a reference for biological rhythms (hereinafter referred to as reference biological rhythms). The reference biological rhythm refers to a general human biological rhythm. The more the biological rhythm of the subject (T) deviates from the reference biological rhythm, the more disrupted the biological rhythm of the subject (T) can be said to be.

[0055] The reference biological rhythm is based on statistical information. This information may be not only numerical data related to the waveform, but also, for example, a function of the waveform. The storage unit (101) stores this information when the air conditioner (10) is shipped. The storage unit (101) may store information output from a server or the like via a network, and may update this information as appropriate. In this case, the control device (100) is connected to the server via a network.

[0056] The reference biological rhythm in the example of Figure 4 is a reference circadian rhythm. The vertical axis of Figure 4 represents a person's core body temperature [°C], and the horizontal axis represents time (hour). The reference biological rhythm has a cycle of approximately 24 hours. The reference biological rhythm includes a minimum value (Tmin) and a maximum value (Tmax) of the core body temperature. In the example of Figure 4, for example, the core body temperature reaches its minimum value (Tmin) at a first time (t1) (e.g., 4:30 AM). Thereafter, the core body temperature gradually rises and reaches its maximum value (Tmax) at a second time (t2) (e.g., 5:00 PM). Thereafter, the core body temperature gradually decreases and reaches its minimum value (Tmin) again. The difference between the minimum value (Tmin) and the maximum value (Tmax) is greater than 1°C.

[0057] The calculation unit (102) constitutes an estimation unit that estimates the biological rhythm of the subject (T). The skin temperature of the subject (T) detected by the biosensor (50) is input to the control device (100). The calculation unit (102) estimates the biological rhythm of the subject (T) based on this skin temperature. There is a correlation between the skin temperature and the core body temperature of the subject (T). Therefore, the calculation unit (102) estimates the biological rhythm of the subject (T) based on a predetermined algorithm stored in the memory unit (101).

[0058] The control device (100) controls the spraying action of the spray device (41) based on the biological rhythm estimated by the calculation section (102) and the reference biological rhythm.

[0059] (5) Operation of air conditioners The air conditioner (10) performs cooling operation, heating operation, and fan operation.

[0060] In the cooling operation, the compressor (22), the outdoor fan (21), and the indoor fan (33) are operated, and the switching mechanism (24) is in the state shown by the solid line in Fig. 1. The refrigerant circuit (R) performs a refrigeration cycle in which the outdoor heat exchanger (23) functions as a condenser and the indoor heat exchanger (32) functions as an evaporator. In the indoor unit (30), air is drawn into the air passage (34) through the air inlet (31a) and cooled by the indoor heat exchanger (32). The cooled air is supplied to the indoor space (S) through the air outlet (31b).

[0061] In the heating operation, the compressor (22), the outdoor fan (21), and the indoor fan (33) are operated, and the switching mechanism (24) is in the state shown by the dashed line in FIG. 1. The refrigerant circuit (R) performs a refrigeration cycle in which the indoor heat exchanger (32) functions as a condenser and the outdoor heat exchanger (23) functions as an evaporator. In the indoor unit (30), air is drawn into the air passage (34) through the air inlet (31a) and heated by the indoor heat exchanger (32). The heated air is supplied to the indoor space (S) through the air outlet (31b).

[0062] In the fan operation, the indoor fan (33) is operated, and the compressor (22) and the outdoor fan (21) are stopped. In the indoor unit (30), air is drawn into the air passage (34) through the air inlet (31a), passes through the indoor heat exchanger (32) which is stopped, and is supplied to the indoor space (S) through the air outlet (31b).

[0063] (6) Control operation of the adjusting device The control operation of the adjustment device (40) will be described with reference to Fig. 5. The following control operation is performed in the cooling operation, heating operation, or fan operation described above.

[0064] In step ST11, the biosensor (50) detects the skin temperature, which is biometric information of the subject (T). A detection signal of the biosensor (50) is input to the control device (100) at predetermined intervals. The storage unit (101) associates the detection signal of the biosensor (50) with the time at which the detection signal was detected and stores the association information at predetermined intervals.

[0065] In step ST12, the calculation unit (102) estimates the biological rhythm of the subject (T) based on the detection signals of the biological sensor (50). Specifically, the control device (100) obtains a waveform indicating periodic fluctuations in core body temperature based on the detection signals stored in the storage unit (101), the times corresponding to these detection signals, and a predetermined algorithm. The control device (100) estimates the biological rhythm of the subject (T) based on the detection signals of the biological sensor (50) for one day, for example, the previous day, stored in the storage unit (101). The control device (100) may estimate the biological signal of the subject (T) based on the average value of skin temperature for each time period over multiple days stored in the storage unit (101).

[0066] In step ST13, the control device (100) determines whether the phase of the biological rhythm of the subject (T) is shifted ahead of the phase of the reference biological rhythm. The shift between the phase of the biological rhythm and the phase of the reference biological rhythm is calculated based on time t1 corresponding to the minimum value (Tmin) of the biological rhythm and the reference biological rhythm, and time t2 corresponding to the maximum value (Tmax) of the biological rhythm and the reference biological rhythm. If a condition (first condition) is met that the phase of the biological rhythm of the subject (T) is shifted ahead of the phase of the reference biological rhythm by a predetermined time (e.g., two hours) or more, the process proceeds to step ST14; otherwise, the process proceeds to step ST16.

[0067] In step ST14, the display unit 36 ​​notifies the subject T that the biological rhythm of the subject T is abnormal. This allows the subject T to know this before the spraying operation (first operation) of step ST15 is performed. In step ST15, the display unit 36 ​​may notify the subject T that the biological rhythm of the subject T is delayed relative to the reference biological rhythm. The display unit 36 ​​may notify the subject T in advance that the first operation of step ST15 will be performed. The display unit 36 ​​may also notify advice for improving the rhythm of the subject T.

[0068] In step ST15, the control device (100) causes the spray device (41) to perform a first operation. Specifically, the control device (100) causes the spray device (41) to spray a useful substance having a stimulating effect a predetermined time (e.g., two hours) before a sleep onset time preset by the subject (T). In the first operation, the spray device (41) continuously sprays the useful substance having a stimulating effect from a predetermined time (e.g., two hours) before the sleep onset time set by the subject (T). This prevents the subject (T) from falling asleep before the sleep onset time. As a result, the biological rhythm of the subject (T) can be shifted backward, i.e., closer to the reference biological rhythm.

[0069] In step ST16, the control device 100 determines whether the phase of the biological rhythm of the subject T is shifted later than the phase of the reference biological rhythm. If a condition (second condition) that the phase of the biological rhythm of the subject T is shifted later than the phase of the reference biological rhythm by a predetermined time (e.g., 2 hours) or more is met, the process proceeds to step ST17; otherwise, the process proceeds to step ST19.

[0070] In step ST17, the display unit 36 ​​notifies the subject T that the biological rhythm of the subject T is abnormal. This allows the subject T to know this before the spraying operation (second operation) of step ST18 is performed. In step ST17, the display unit 36 ​​may notify the subject T that the biological rhythm of the subject T is delayed relative to the reference biological rhythm. The display unit 36 ​​may notify the subject T in advance that the second operation of step ST18 will be performed. The display unit 36 ​​may also notify advice for improving the phase of the biological rhythm of the subject T.

[0071] In step ST17, the control device (100) causes the spray device (41) to perform a second operation. Specifically, the control device (100) causes the spray device (41) to spray a useful substance having a stimulating effect at a wake-up time preset by the subject (T). In the second operation, the spray device (41) continuously sprays the useful substance having a stimulating effect for a predetermined time (e.g., two hours) after the wake-up time. This prevents the subject (T) from failing to wake up at the wake-up time. As a result, the biological rhythm of the subject (T) can be brought forward, that is, closer to the reference biological rhythm.

[0072] If the first condition of step ST13 and the second condition of step ST16 are not satisfied, the process proceeds to step ST19. In step ST19, the display unit (36) notifies the subject (T) that the biological rhythm of the subject (T) is normal. In this case, the spray device (41) does not perform the first action or the second action.

[0073] (7) Effects of the embodiment (7-1) The adjustment device (40) of this embodiment includes a spray device (41) that sprays a useful substance having a stimulating effect into a target space (S) in which a subject (T) is present, a biosensor (50) that is a detection unit that detects bioinformation of the subject (T), and a control device (100) that controls the spraying operation of the spray device (41) based on the biorhythm of the subject (T) estimated based on the skin temperature as bioinformation detected by the biosensor (50) and reference data (reference biorhythm) that serves as a reference for the biorhythm.

[0074] By spraying useful substances into the target space (S), it is possible to provide an awakening effect to the subject (T). As a result, it is possible to adjust the biological rhythm of the subject (T). Unlike light stimulation, useful substances act more directly on the subject (T), which can improve the effect of adjusting the biological rhythm.

[0075] If the subject (T) is a child, improving the child's biological rhythm can prevent school absenteeism and learning disabilities. If the subject is an adult, improving the biological rhythm of the adult can improve productivity at work and improve sensitivity to cold. If the subject is elderly, improving the rhythm of the elderly can prevent dementia and improve their ability to adapt to social life in elderly care facilities.

[0076] (7-2) When the control device (100) determines that the phase of the biological rhythm of the subject (T) is out of phase with the reference data, it controls the spraying operation of the spray device (41) so as to bring the phase of the biological rhythm of the subject (T) closer to the reference data.

[0077] Specifically, when the control device (100) determines that the phase of the biological rhythm of the subject (T) is shifted ahead of the reference data, it causes the spray device (41) to spray a substance having a stimulating effect a predetermined time before the set time when the subject (T) falls asleep.

[0078] This prevents the subject (T) from falling asleep before the sleep onset time, and shifts the subject (T)'s biological rhythm later. In particular, by repeatedly performing this spraying operation (first operation), the subject (T)'s biological rhythm can be improved.

[0079] The spray device (41) performs the first action from a predetermined time before the sleep onset time until the sleep onset time, thereby effectively preventing the subject (T) from falling asleep before the sleep onset time.

[0080] (7-3) When the control device (100) determines that the phase of the biological rhythm of the subject (T) is shifted later than the reference data, it causes the spray device (41) to spray a substance having a stimulating effect at the set wake-up time of the subject (T).

[0081] This can encourage the subject (T) to wake up at the wake-up time, and can shift the subject (T)'s biological rhythm forward. In particular, by repeatedly performing this spraying operation (second operation), the subject (T)'s biological rhythm can be improved.

[0082] The spray device (41) performs the second action from the wake-up time until a predetermined time after the wake-up time. This effectively encourages the subject (T) to wake up at the wake-up time. The spray device (41) may perform the second action from a predetermined time before the wake-up time until the wake-up time. The spray device (41) may perform the second action from a predetermined time before the wake-up time until a predetermined time after the wake-up time.

[0083] (7-4) The control device (100) includes a display unit (36) as a notification unit that notifies the subject (T) of an abnormality when it determines that the subject (T)'s biological rhythm is out of sync with the reference data. This allows the subject (T) to understand that his or her own biological rhythm is out of sync with the reference data. Therefore, the subject (T) can be encouraged to improve his or her biological rhythm.

[0084] The display unit 36 ​​notifies the subject T of an abnormality before the spraying operation of the spray device 41. This allows the subject T to know in advance that the spraying operation will be performed to improve his / her biological rhythm.

[0085] (8) Variations The above embodiment may be configured as follows: The following describes the differences from the above embodiment.

[0086] (8-1) Variation 1 The air conditioner (10) of the first modification differs from the above embodiment in the configuration of the adjustment device (40). As shown in FIG. 6, the spray device (41) of the adjustment device (40) of the first modification has a first spray section (41A) and a second spray section (41B). The first spray section (41A) has a first container (42A), a first supply channel (43A), and a first outlet (44A). As in the above embodiment, the first container (42A) stores an undiluted solution of a useful substance having a stimulating effect. The second spray section (41B) has a second container (42B), a second supply channel (43B), and a second outlet (44B). The second container (42B) stores an undiluted solution of a useful substance having a sedative effect.

[0087] The first spraying unit (41A) has a first driving source (45A) for atomizing a useful substance having a stimulating effect, and the second spraying unit (41B) has a second driving source (45B) for atomizing a useful substance having a sedative effect. The first driving source (45A) and the second driving source (45B) are composed of a pressure pump, an ultrasonic generator, an electrode for electrostatic spraying, etc. In other words, the first spraying unit (41A) and the second spraying unit (41B) are composed of a pressure type, an ultrasonic type, an electrostatic spray type, etc.

[0088] The sedative substance is a substance consisting of one of theanine, glycine, serine, gamma-aminobutyric acid (GABA), hastatoside, verbenaline, ornithine, crocin, or crocetin, or a mixture containing two or more of these. The sedative useful substance imparts a sedative effect to the subject (T) when absorbed into the body of the subject (T). The useful substance is preferably absorbed into the body through the subject's mouth. Furthermore, the useful substance preferably excludes substances that are absorbed through the nasal epithelial olfactory cells and act on the subject. The useful substance preferably excludes substances that stimulate the olfactory nerve in the subject (T). The useful substance is preferably an odorless substance, and is preferably a substance that does not affect the human sense of smell. The useful substance may also be a substance containing an odor component adjusted to a concentration at which humans cannot detect the odor.

[0089] The control device (100) controls the spraying operations of the first spray section (41A) and the second spray section (41B). The control operation of the adjustment device (40) will be described in detail with reference to FIG.

[0090] In the first modification, if the phase of the biological rhythm of the subject (T) is shifted ahead of the reference biological rhythm (YES in step ST13), the display unit (36) notifies the user of the abnormality in step ST14. Next, in step ST15 of the first modification, the control device (100) causes the first spraying unit (41A) to perform a spraying operation (first operation). In the first operation in step ST15, similar to the above embodiment, the first spraying unit (41A) sprays a useful substance having a stimulating effect from a predetermined time before the sleep onset time. The first operation is performed from a predetermined time before the sleep onset time until the sleep onset time. As a result, similar to the embodiment, the phase of the biological rhythm can be shifted back by encouraging the subject (T) to wake up.

[0091] If the phase of the biological rhythm of the subject (T) is delayed relative to the reference biological rhythm (YES in step ST16), the display unit (36) notifies the user of the abnormality in step ST17. Next, in step ST20 of the first modification, the control device (100) causes the second spraying unit (41B) to perform a spraying operation (third operation). In the third operation of step ST20, the second spraying unit (41B) sprays a useful substance having a sedative effect from a predetermined time before the sleep onset time. The third operation is performed from a predetermined time before the sleep onset time until the sleep onset time. This can encourage the subject (T) to fall asleep by the sleep onset time. As a result, the biological rhythm of the subject (T) can be brought forward, that is, closer to the reference biological rhythm.

[0092] In the spray device (41) of the first modification, the first container (42A) and the second container (42B) may share one supply path (43) and one driving source (45).

[0093] In the first modification, the second operation of step ST18 may be executed in the same manner as in the first embodiment.

[0094] (8-2) Variation 2 The adjustment device (40) of the second modification adjusts the amplitude of the biological rhythm of the subject (T). Specifically, when the amplitude of the biological rhythm of the subject (T) is small (flattened) relative to the reference data (reference biological rhythm), the adjustment device (40) controls the spraying operation of the spray device (41) so as to bring the amplitude closer to the reference biological rhythm.

[0095] 8, in the second modification, the biosensor (50) detects bioinformation (skin temperature) in step ST31. In step ST32, the control device (100) estimates the biorhythm of the subject (T) based on the detection signal of the biosensor (50).

[0096] In step ST33, the control device 100 determines whether a third condition is satisfied, that is, the amplitude of the biological rhythm of the subject T is smaller than the amplitude of the reference biological rhythm by a predetermined amount. Specifically, if the amplitude of the biological rhythm of the subject T is smaller than the temperature difference ΔT (e.g., 1°C) between the minimum value (Tmin) and the maximum value (Tmax) of the reference biological rhythm, the process proceeds to step ST34; otherwise, the process proceeds to step ST37.

[0097] In step ST34, the display unit 36 ​​notifies the subject (T) that the biological rhythm of the subject (T) is abnormal. This allows the subject (T) to know this before the spraying operation (fourth operation) of step ST35 and the spraying operation (fifth operation) of step ST36 are performed. In step ST34, the display unit 36 ​​may notify the subject (T) that the amplitude of the biological rhythm of the subject (T) is small (flattened). The display unit 36 ​​may notify the subject (T) in advance that the fourth operation of step ST35 or the fifth operation of step ST36 will be performed. The display unit 36 ​​may also notify advice for improving the amplitude of the biological rhythm of the subject (T).

[0098] In step ST35, the control device (100) causes the spraying device (41) to perform a spraying operation (fourth operation). In the fourth operation of step ST35, the spraying device (41) sprays a useful substance having a stimulating effect from the set wake-up time until a predetermined time after. This can increase the amplitude of the biological rhythm by encouraging the subject (T) to be active during the day. The end time of the fourth operation is preferably a time (e.g., 4:00 PM to 6:00 PM) corresponding to the maximum value (Tmax) of the biological rhythm of the subject (T).

[0099] In step ST36, the control device (100) causes the spraying device (41) to perform a spraying operation (fifth operation). In the fifth operation of step ST36, the spraying device (41) sprays a useful substance having a sedative effect from a predetermined time before the set sleep onset time. The fifth operation is performed from a predetermined time before the sleep onset time until the sleep onset time. This can promote nighttime sleep in the subject (T) and increase the amplitude of the biological rhythm. The start time of the fifth operation is preferably a predetermined time after the time corresponding to the maximum value (Tmax) of the biological rhythm of the subject (T) (e.g., 4:00 PM to 6:00 PM).

[0100] If the third condition of step ST33 is not satisfied, the process proceeds to step ST37. In step ST37, the display unit (36) notifies the subject (T) that the biological rhythm of the subject (T) is normal. In this case, the spray device (41) does not perform the fourth action or the fifth action.

[0101] In the second modification, when the third condition is met, the control device (100) may control the spraying operation of the spray device (41) so that only one of the fourth operation and the fifth operation is performed.

[0102] In a second modification, the control device 100 may determine that the biological rhythm of the subject T is flattened based on the activity level of the subject T. The activity level of the subject T is biological information of the subject T and can be measured, for example, by an acceleration sensor worn by the subject T. The acceleration sensor is an example of a detection unit.

[0103] (8-3) Variation 3 The adjustment device (40) of the third modification adjusts the cycle of the biological rhythm of the subject (T). Specifically, when the cycle of the biological rhythm of the subject (T) deviates from a reference biological rhythm, the adjustment device (40) controls the spraying operation of the spray device (41) so as to bring the cycle closer to the reference biological rhythm.

[0104] 9, in Modification 3, the biosensor (50) detects bioinformation (skin temperature) in step ST41. In step ST42, the control device (100) estimates the biorhythm of the subject (T) based on the detection signal of the biosensor (50).

[0105] In step ST43, the control device 100 determines whether the period of the biological rhythm of the subject T is shorter than the period of the reference biological rhythm (24 to 25 hours). If the fourth condition that the period of the biological rhythm is shorter than the period of the reference biological rhythm is met, the process proceeds to step ST44; otherwise, the process proceeds to step ST46.

[0106] In step ST44, the display unit 36 ​​notifies the subject T that the biological rhythm of the subject T is abnormal. This allows the subject T to know this before the spraying action (first action) of step ST45 is performed. In step ST44, the display unit 36 ​​may notify the subject T that the cycle of the biological rhythm is short. The display unit 36 ​​may notify the subject T in advance that the first action of step ST45 will be performed. The display unit 36 ​​may also notify advice for improving the cycle of the biological rhythm of the subject T.

[0107] In step ST45, the control device (100) causes the spray device (41) to perform a spraying operation (first operation similar to that in the embodiment). In the first operation in step ST45, the spray device (41) continuously sprays a useful substance having a stimulating effect from a predetermined time (e.g., two hours) before the set sleep onset time. This lengthens the cycle of the biological rhythm, bringing it closer to the reference biological rhythm.

[0108] In step ST46, the control device 100 determines whether the period of the biological rhythm of the subject T is longer than the period of the reference biological rhythm (24 to 25 hours). If the fifth condition that the period of the biological rhythm is longer than the period of the reference biological rhythm is met, the process proceeds to step ST47; otherwise, the process proceeds to step ST49.

[0109] In step ST47, the display unit 36 ​​notifies the subject T that the biological rhythm of the subject T is abnormal. This allows the subject T to know this before the spraying operation (second operation) of step ST48 is performed. In step ST48, the display unit 36 ​​may notify the subject T that the period of the biological rhythm is long. The display unit 36 ​​may notify the subject T in advance that the second operation of step ST48 will be performed. The display unit 36 ​​may also notify advice for improving the period of the biological rhythm of the subject T.

[0110] In step ST48, the control device (100) causes the spray device (41) to perform a spraying operation (the second operation similar to that of the embodiment). In the second operation of step ST48, the spray device (41) continuously sprays the useful substance having a stimulating effect for a predetermined time (e.g., two hours) from the wake-up time. This can prevent the subject (T) from failing to wake up at the wake-up time. This can shorten the cycle of the biological rhythm and bring it closer to the reference biological rhythm.

[0111] If the fourth condition of step ST43 and the fifth condition of step ST44 are not satisfied, the process proceeds to step ST49. In step ST49, the display unit (36) notifies the subject (T) that the biological rhythm of the subject (T) is normal. In this case, the spray device (41) does not perform the first action or the second action.

[0112] When the fifth condition of step ST43 is satisfied, the control device (100) may control the spray device (41) to perform the third operation of step ST20 of Modification 1. In the third operation, the spray device (41) sprays a useful substance having a sedative effect from a predetermined time before the sleep-onset time until the sleep-onset time. This can shorten the period of the biological rhythm of the subject (T).

[0113] In a third modification, the period of the reference biological rhythm may be changed according to the age of the subject (T). This is because the period of the reference biological rhythm changes according to the age of the subject (T). Information on the age of the subject (T) is input to the control device (100) via the remote controller (35). The control device (100) corrects the period of the reference biological rhythm according to the input age of the subject (T).

[0114] (8-4) Variation 4 The adjustment device (40) of the fourth modification controls the spraying operation of the spray device (41) based on the volume of the indoor space (S), which is the target space. Specifically, the volume of the indoor space (S) is input to the control device (100). This volume information is input to the control device (100) by, for example, the subject (T) operating the operation unit (37) of the remote controller (35). The adjustment device (40) adjusts the spray time, spray rate, and concentration of the useful substance based on the input volume.

[0115] Specifically, for example, when the volume is relatively large, the spray time of the useful substance is lengthened, the spray speed is increased, or the concentration of the useful substance is increased in the above-mentioned spraying operations (first to fifth operations). This ensures that the stimulating or sedative effects of the useful substance can be imparted to the subject (T) even when the volume of the indoor space (S) in which the subject (T) is present is relatively large.

[0116] For example, when the volume is relatively small, the spray time of the useful substance is shortened, the spray speed is slowed, or the concentration of the useful substance is lowered in the above-mentioned spraying operations (first to fifth operations). This makes it possible to prevent an excessive amount of useful substance from being supplied to the room space (S) where the subject (T) is present when the volume of the room space (S) is relatively small.

[0117] (8-5) Variation 5 The adjustment device (40) according to the fifth modification controls the spraying action of the spray device (41) based on the life rhythm of the subject (T). Here, the life rhythm means a person's behavior from waking up in the morning until going to bed. The life rhythm particularly includes the rhythm of a person's falling asleep and waking up. If the life rhythm of the subject (T) is disturbed, the subject's biological rhythm is also disturbed.

[0118] As shown in FIG. 10 , the adjustment device (40) has a sleep sensor (60) as a detection unit. The sleep sensor (60) detects the heartbeat, breathing, or body movements of the subject (T). The sleep sensor (60) may be a wearable type that is attached to the subject (T), or a non-restraint type that is attached to bedding such as a bed. The control device (100) estimates the time when the subject (T) falls asleep and wakes up based on the signal detected by the sleep sensor (60).

[0119] A reference life rhythm as reference data of the subject (T) is input to the storage unit (101) of the control device (100). The reference life rhythm includes a reference sleep onset time and a reference wake-up time. This information is input to the control device (100) via, for example, the operation unit (37) of the remote controller (35).

[0120] The control device (100) compares the estimated life rhythm of the subject (T) with a reference life rhythm, and if the life rhythm of the subject (T) deviates from the reference life rhythm, the control device (100) controls the spray device (41).

[0121] Specifically, for example, if the subject (T)'s sleep onset time and wake-up time are later than the sleep onset time and wake-up time of the reference life rhythm, it can be determined that the subject (T) stays up late into the night and wakes up late in the morning. In this case, the control device (100) causes the spray device (41) to perform a third operation. In the third operation, the spray device (41) sprays a useful substance having a sedative effect from a predetermined time before the sleep onset time. This can encourage the subject (T) to fall asleep by the sleep onset time, thereby hastening the time of sleep onset.

[0122] When the subject (T)'s sleep onset time and wake-up time are later than the sleep onset time and wake-up time of the reference life rhythm, respectively, the control device (100) causes the spray device (41) to perform a second operation. In the second operation, the spray device (41) continuously sprays the useful substance having a stimulating effect for a predetermined time after the wake-up time. This can encourage the subject (T) to wake up in the morning, and can advance the subject (T)'s wake-up time.

[0123] Furthermore, for example, when the subject (T)'s sleep onset time and wake-up time are earlier than the sleep onset time and wake-up time of the reference life rhythm, respectively, the control device (100) causes the spray device (41) to perform a first operation. In the first operation, the spray device (41) continuously sprays a useful substance having a stimulating effect from a predetermined time before the set sleep onset time until the set sleep onset time. This prevents the subject (T) from falling asleep before the sleep onset time. As a result, the subject (T) can fall asleep earlier.

[0124] In the fifth modification, the spraying operation as described above makes it possible to bring the life rhythm of the subject (T) closer to the reference life rhythm.

[0125] In a fifth modification, the adjustment device (40) may estimate the time when the subject person (T) falls asleep and wakes up based on the ON / OFF operation of the lights in the indoor space (S).

[0126] In the fifth modification, the adjustment device (40) may estimate the times of events other than falling asleep and waking up, and estimate these as the life rhythm. Examples of other events include work events, meal events, and bathing events.

[0127] The control device (100) estimates the time of a work event based on the ON / OFF of the lights on the office desk, the ON / OFF of the personal computer used for work, the presence or absence of detection by a motion sensor placed in the office space, the ON / OFF of the air conditioner in the office space, the opening and closing of the door facing the office space, etc.

[0128] The control device (100) estimates the time of a meal event based on the ON / OFF of the lighting in the dining space, whether or not a motion sensor placed in the dining space is detected, whether or not the air conditioner in the dining space is ON / OFF, and whether or not the door facing the dining space is opened or closed.

[0129] The control device (100) estimates the time of a bathing event based on the ON / OFF of the lights in the bathroom or changing room, the ON / OFF of the water heater corresponding to the bathroom, the ON / OFF of the ventilation fan in the bathroom or changing room, the ON / OFF of the air conditioner in the bathroom or changing room, the opening and closing of the door facing the bathroom or changing room, etc.

[0130] The control device 100 may use the subject T's self-reporting of the times of these events, in which case the subject T inputs this information into the control device 100 via the operation unit 37 of the remote controller 35.

[0131] The control device (100) controls the spraying operation of the spray device (41) based on the life rhythm estimated from these events and the reference life rhythm. Specifically, when the time of a work event, a meal event, or a bathing event is later than the reference event time, the spray device (41) performs the second or third operation. Conversely, when the time of a work event, a meal event, or a bathing event is earlier than the reference event time, the control device (100) performs the first operation.

[0132] (9) Other embodiments The above-described embodiment and each of the modified examples may be configured as follows.

[0133] The conditioning device 40 may be applied to devices other than the air conditioning system 1. The conditioning device 40 may be, for example, a stationary spray unit that is installed on the floor or tabletop of the indoor space S.

[0134] The air conditioner (10) to which the adjustment device (40) is applied may be an air purifier that purifies the air, a humidity control device that adjusts the humidity of the air, or a ventilation device that ventilates the indoor space (S).

[0135] The calculation unit (102) and the storage unit (101) of the control device (100) may be provided in the first control unit (C1) or the third control unit (C3). The control device (100) may be provided in a communication terminal capable of communicating with the spray device (41). The communication terminal includes a smartphone, a personal computer, a tablet terminal, a wearable terminal, etc. The control device (100) may be a server device capable of communicating with the spray device (41) via a network.

[0136] The biosensor 50 may detect a body temperature other than skin temperature as bioinformation of the subject T. This body temperature may be a core body temperature, a peripheral skin temperature, or a core temperature. The biosensor 50 may also detect melatonin or cortisol in the saliva of the subject T as bioinformation. In this case, the control device 100 estimates the endocrine rhythm as a biorhythm based on the melatonin or cortisol.

[0137] The control device 100 may use a change in skin color of the subject T when estimating the biorhythm of the core body temperature. The change in skin color correlates with the core body temperature of the subject T and is therefore useful for estimating the biorhythm. The change in skin color can be detected by a camera serving as a detector.

[0138] The spray device (41) may be a device that mixes and releases useful substances into a vortex ring formed by vibrating a vibrating plate serving as a driving source (45).

[0139] The control device (100) may change the start time and end time of spraying of the first to fifth actions based on input values. The subject (T) can input these input values ​​to the control device (100) via the operation unit (37) of the remote controller (35).

[0140] The device that inputs information to the control device 100 may be a communication terminal other than the remote controller 35. The communication terminal may be a smartphone, a personal computer, a tablet terminal, a wearable terminal, or the like.

[0141] The notification unit may notify the abnormality of the subject (T) by sound or light.

[0142] Although the embodiments and modifications have been described above, it will be understood that various modifications in form and details are possible without departing from the spirit and scope of the claims. Furthermore, the above embodiments, modifications, and other embodiments may be combined or substituted as appropriate as long as the functionality of the subject matter of the present disclosure is not impaired.
