Therefore, the control device 50 can share data obtained from each device, and can perform overall operation control in conjunction with each device.

  The air conditioner 10 includes an indoor unit and an outdoor unit, and includes a control unit (not shown) that feeds back input information from a sensor to control the air conditioning operation, and a communication unit (not shown) that performs communication control. )).

  Specifically, the control unit in the air conditioner 10 feeds back the outputs of the indoor temperature / humidity detection sensor 11 that detects the indoor temperature and humidity, and the surface temperature detection sensor 12 that measures the surface temperature of people, floors, windows, and the like. Control air conditioning operations such as cooling and heating operations. In addition, the control part can adjust the direction of an airflow by the output of the surface temperature detection sensor 12, and can perform the air conditioning by a blowing airflow efficiently.

  Moreover, the communication part in the air conditioner 10 can communicate bidirectionally with the air conditioner 20, the sleep state detector 30, the bedding 40, and the control device 50, and can share data.

  The sleep state detector 30 detects a sleep state from a measurement result related to a person, and may use a person using infrared rays or radio waves, or may measure a person's movement in a non-contact manner by image analysis using a camera. .

  Moreover, in this Embodiment 1, although this sleep state detector 30 was used as an independent apparatus, you may provide in the air conditioning equipment 10 or the air conditioning equipment 20. FIG. Further, as a specific example of the sleep state detector 30, an acceleration detection sensor may be applied and installed in the bedding 40 so as to measure a person's movement. Alternatively, an application that can be downloaded to a mobile phone or a tablet device may be used as the sleep state detector 30.

  As shown in FIG. 2, the bedding 40 includes a heater 41 and a blower 42 in the housing. The air sucked by the blower 42 is heated by the heater 41 to become high-temperature air, and is blown to the bag-like dry bag 45 through the duct 44.

  The drying bag 45 is provided with a bed temperature and humidity detection sensor 43. The drying bag 45 is installed in the lower part of the mattress 46, and the sleeper sleeps between the mattress 46 and the comforter 47. When the bed temperature / humidity detection sensor 43 is used when not at bedtime, the bed temperature / humidity detection sensor 43 may be installed between the mattress 46 and the comforter 47.

  The control device 50 includes a calculation unit 51 and a control unit 52 and aggregates data obtained from the air conditioner 10, the air conditioner 20, the sleep state detector 30, and the bedding 40. And the control apparatus 50 determines a sleeper's state by the calculation based on the collected data, and performs overall control of the operation of each device.

  In the first embodiment, the control device 50 is an independent device, but may be provided in the air conditioner 10, the air conditioner 20, the sleep state detector 30, or the bedding 40. Further, a configuration without the air conditioner 20 may be considered.

  On the other hand, similarly to the bedroom S, the living room T is also provided with an air conditioner 10A and an air conditioner 20A. The air conditioner 10A includes an indoor temperature / humidity detection sensor 11A, a surface temperature detection sensor 12A, a communication unit, and a control unit. Each of the air conditioner 10 </ b> A and the air conditioner 20 </ b> A can communicate with the control device 50. Therefore, each device in the bedroom S and each device in the living room T can be integratedly controlled by the control device 50.

Next, the sleep state will be described in detail with reference to FIG.
Between the time when a person starts falling asleep and the next time they wake up, the transition is such that the sleep becomes deeper in the order of REM sleep, sleep depth 1, 2, 3, 4, and then sleep depth 3, 2, 1, The sleep cycle of transitioning to REM sleep is usually repeated with a period of about 90 minutes.

  FIG. 3 is an explanatory diagram showing changes in sleep state from the start of sleep of a person to the wake-up in Embodiment 1 of the present invention. In addition, in this FIG. 3, with the change of the sleep state, the change of the deep body temperature (the temperature of the center of the body (rectal temperature)), which is deeply related to sleep, is indicated by the dotted line. The relationship is also illustrated as the height of the vertical bar.

  First, sleep is broadly classified into REM sleep, which is generally light sleep, and non-REM sleep, which is deep sleep. Sleep is divided into more detailed sleep states, and six states of awakening, REM sleep, and sleep depths 1, 2, 3, and 4 are defined. Here, the sleep depths 1, 2, 3, and 4 are obtained by further dividing non-REM sleep into four stages.

  Next, the relationship between the electroencephalogram and sleep will be described in detail using Tables 1 and 2. Table 1 is a table showing the correspondence between main types of electroencephalograms and frequency bands.

  The electroencephalogram is named for each frequency band as shown in Table 1, and has different physiological significance. In general, in a healthy person, many α waves appear mainly in the back of the head in each of the states of rest, closed eyes, and arousal.

  Table 2 is an international classification table for determination of sleep depth based on brain waves.

  As shown in Table 2, the depth of sleep (sleep depth) is classified based on the frequency of brain waves and the like.

  In the wakefulness stage (stage W), in addition to α waves, high-amplitude continuous electromyograms, rapid eye movements and blinks often appear.

  The sleep depth 1 (stage 1) is referred to as a stagnation period or a sleep period. It is in a state of lasting. The series of alpha waves observed at awakening loses rhythm and gradually flattens. In addition, a slow wave of a low potential, that is, a θ wave appears irregularly in a brain wave at a sleep depth of 1, and a β wave is also mixed. Further, the α wave is 50% or less of the awakening period. At the second half of the sleep depth 1, a cranial apex wave (hump or V wave) appears.

  The sleep depth 2 (stage 2) is a state in which light sleep is raised. A sleep spindle wave and a K complex wave appear in an electroencephalogram with a sleep depth of 2. The sleep spindle wave is a waveform of about 12 Hz to 14 Hz that appears at the top of the head. The K composite wave is a composite wave composed of a biphasic high-amplitude slow wave resembling a cranial apex wave followed by a fast wave.

  Sleep depth 3 (stage 3) is a stage in which a slow wave (δ wave) having an electroencephalogram of 2 Hz or less and an amplitude between vertices of 75 μV or more occupies 20% or more and less than 50%. It is quite deep sleep and is not perceived unless it is a very strong stimulus.

  Sleep depth 4 (stage 4) is a state in which brain waves occupy 50% or more of slow waves (δ waves) of 2 Hz or less and 75 μV or more. The sleep depth 3 and the sleep depth 4 are collectively referred to as slow wave sleep. These sleep stages from sleep depth 1 to sleep depth 4 are mainly non-REM sleep.

REM sleep is sleep characterized by the following three.
(Feature 1) A low-amplitude pattern similar to sleep depth 1 appears in the electroencephalogram (Feature 2) Rapid eye movement (REM) appears (Feature 3) Reduced anti-gravity muscle tone that maintains body posture In many cases, it is said that the REM had been dreamed when it was awakened by stimulating during REM sleep.

  Next, the operation of the pleasant sleep environment control system according to Embodiment 1 of the present invention will be described. FIG. 4 is a flowchart showing a series of control operations of the pleasant sleep environment control system according to Embodiment 1 of the present invention.

  In the following description using FIG. 4, in step S <b> 1 to step S <b> 5, an example is given in which the thermal sensation is determined by the air conditioner 10 </ b> A in the living room T, and then the sleeping person moves from the living room T to the bedroom S. Explained.

  In step S1, the air conditioner 10A in the living room T is performing a cooling operation or a heating operation, and the air conditioner 20A in the living room T is performing a humidifying operation, and the operation of the sleep control environment is started. .

  In step S2, the control unit in the air conditioner 10A measures the temperature distribution of the living room T based on the detection result of the surface temperature detection sensor 12A of the air conditioner 10A, and detects the position and skin temperature of the person. Since humans are heating elements, they are above room temperature. Accordingly, the control unit identifies the position of the person and the skin temperature by extracting the characteristic portion of the temperature distribution, and proceeds to step S3.

  In step S3, the control unit detects the indoor temperature and humidity based on the detection result of the indoor temperature and humidity detection sensor 11A, and the skin temperature data and the indoor temperature and humidity data detected in step S2 are transmitted via the communication unit. It transmits to the control apparatus 50. Then, the process proceeds to step S4.

  In step S4, the control device 50 determines the thermal sensation of the sleeping person from the skin temperature data and the room temperature / humidity data obtained from the air conditioner 10A, and starts the sleep environment control of the bedroom according to the state. For example, the control device 50 can classify and determine the thermal sensation of a sleeping person as “hot”, “calm”, and “cold”.

  In addition to judging the temperature of the sleeping person from the skin temperature, the sleeping person himself / herself may be “living in a hot bath” or “the body is cold soon after returning home”. It is good also as a structure which inputs a state from a remote control etc. and gives to the control apparatus 50. FIG.

  In addition, the control device 50 communicates with an action log function such as a wearable sensor, obtains an action and a room temperature state before going to bed, predicts a body temperature state by a calculation unit, and determines a sleeping environment control of the bedroom. Also good. Then, the process proceeds to step S5 and step S6.

  In step S <b> 5, the control device 50 detects the state of the bedding based on the detection result of the bed temperature / humidity detection sensor 43. Further, in step S6, the control device 50 controls the heater 41 and the blower 42 of the bedding 40 in accordance with the thermal sensation of the sleeping person and the state in the bed, and starts the bedding preheating / precooling operation. And it progresses to step S7-step S9.

  In steps S1 to S5, the thermal sensation is determined by the air conditioner 10A in the living room T, and the sleeper subsequently moved to the bedroom S. However, even after entering the bedroom S, the thermal sensation is determined. Good.

  In step S7, the sleeper moves to the bedroom S, enters the bedding, and goes to bed. In step S <b> 8, when the sleeper is confirmed based on the detection result of the in-bed temperature / humidity detection sensor 43, the control device 50 starts the bedding pleasant sleep control operation. Further, in step S9, the control device 50 starts the indoor sleep control operation.

  Details of the bedding sleep control operation in step S8 and the indoor sleep control operation in step S9 will be described in detail with reference to FIGS. Then, the process proceeds to step S10 and step S11.

  In step S <b> 10, the sleeper can get up in an environment that is easy to wake up according to the sleep rhythm by the driving of the comfortable sleep environment control by the control device 50. Furthermore, in step S11, when it is confirmed by the detection result of the temperature / humidity detection sensor 43 in the bed that the sleeping person has woken up, the control device 50 stops the operation of the comfortable sleep environment control and ends the series of processes. .

  Next, specific operations of the bedding pleasant sleep control operation and indoor pleasant sleep control operation executed by the pleasant sleep environment control system according to Embodiment 1 of the present invention will be described with reference to FIGS.

  FIG. 5 is a diagram showing a heating distribution of the bedding according to Embodiment 1 of the present invention. As shown in FIG. 5, the drying bag 45 of the bedding 40 divides the air blown from the duct 44 into an area A, an area B, and an area C, and blows or warms the air. The most upstream side to which the duct 44 is connected is the area A. The area A is connected to the area B through the check valve 48A, and the area C is connected to the downstream side through the check valve 48B. ing.

  Area A is an area where sleepers do not get too much during sleep and do not interfere with sleep. Area B is an area that covers the end of the limb that plays the role of a radiator for adjusting body temperature. Furthermore, the area C is an area that covers the head and the body part that needs to be cooled to promote falling asleep, that is, the deep part temperature needs to be lowered.

  By performing the warming air blow in such an order, it is possible to warm from a part preferential to body temperature adjustment, particularly warming, and it is possible to prevent the influence on the head that is not desired to be warmed.

  In FIG. 5, check valves 48A and 48B are provided and the temperature is controlled for each area by one air passage. However, the duct 44 is divided and divided air is blown by a damper (not shown). Also good.

  6 to 11 are a driving pattern diagram and a graph showing a sleeper state change for explaining a specific operation example of the pleasant sleep environment control system according to Embodiment 1 of the present invention. More specifically, sleep control suitable for each of the skin temperature corresponding to the state of the person before sleep detected by the surface temperature detection sensor 12 and the result detected by the bed temperature / humidity detection sensor 43 will be described. Is.

  FIG. 6 shows the control when a person who is going to sleep in the winter is in the heated living room T and the skin temperature is sufficiently accustomed to the environment before going to bed. The skin temperature is about 33 ± 1 ° C. in a comfortable environment, depending on the site and individual differences.

  After bedtime, you can quickly fall asleep by lowering the deep temperature quickly. Therefore, it is necessary to promote heat dissipation from the end portions such as limbs. Therefore, the control device 50 controls the areas A and B to be slightly higher than the skin temperature by weakly driving the bedding 40 before going to bed, and prevents the body part and the head from being heated. . By doing so, heat dissipation can be accelerated and the deep temperature can be lowered quickly.

  In addition, warming that feels hot is counterproductive, and after bedtime, the temperature in the bed is balanced by the amount of heat generated by the bedridden and the heat retention of the bedding 40. Therefore, the control device 50 turns off the heating of the bedding 40 after going to bed.

  In addition, the control device 50 controls the heating operation of the air conditioner 10 to be OFF when going to bed. Thereby, since the head is not heated, the deep temperature can be quickly reduced.

  When a bedridden gets up close, the deep temperature gradually rises. Therefore, when the control device 50 determines that the sleep of the sleeper has become shallow due to the detection result of the sleep state detector 30 and is approaching to wake up, the control device 50 turns on the air conditioner 10 and the bedding 40 to help increase the deep temperature. Control. At this time, since rapid heating awakens the sleeping person, the control device 50 controls the air conditioner 10 and the bedding 40 to perform weak operation.

  FIG. 7 shows the control in the winter, when a person who is going to sleep is in the heated living room T before going to bed, is hot and hot, or the deep temperature has risen too much due to bathing. Is.

  If the skin temperature is higher than usual and the bedding 40 is heated in this state, heat cannot be released from the limbs, and it is difficult to fall asleep. Therefore, when the skin temperature is close to or higher than 37 ° C. by the surface temperature detection sensor 12, the control device 50 controls the air conditioner 10 to a temperature preferred by the sleeper, and the bedding 40 Is controlled not to warm. As a result, the skin temperature can be quickly lowered and heat can be released appropriately. Control from falling asleep to getting up is the same as in FIG.

  FIG. 8 shows a state in which a person who will go to bed in the winter is shortly after returning home, and has not been able to take a bath or has a skin temperature lower than, for example, 30 ° C. for reasons such as coldness. It is shown.

  In this state, the control device 50 controls the air conditioner 10 to a sleeper's favorite temperature, controls the bedding 40 with strong operation, and heats it properly and rapidly. As a result, even when there is no time for bathing or the like, the limbs can be warmed and heat can be dissipated quickly. Control from falling asleep to getting up is the same as in FIG.

  FIG. 9 shows the control when the person who is going to sleep in the summer is in the living room T which is appropriately cooled and the skin temperature is sufficiently adapted to the environment. The skin temperature is about 33 ± 1 ° C. in a comfortable environment, depending on the site and individual differences.

  Since the room temperature is high in summer, it is not necessary to heat the bedding 40 if the skin temperature reaches a temperature at which heat can be radiated, and heat radiation can be promoted by lowering the temperature and humidity on the skin surface. Therefore, in this state, the control device 50 controls the air conditioner 10 to a sleeper's favorite temperature, and controls the bedding 40 as a weak air blowing operation. As a result, by cooling the head, the deep temperature (brain temperature) can be lowered, and heat radiation at the end of the limb can be promoted, so that sleep can be accelerated.

  Moreover, the control apparatus 50 is controlled to continue driving | running of the air conditioning equipment 10 until it determines with deep sleep by the detection result of the sleep state detector 30. FIG. And after determining that it is deep sleep, the control apparatus 50 controls the air conditioner 10 so that preset temperature may be raised a little and energy-saving operation may be performed in order to suppress sleep and to suppress an electricity bill.

  Further, the control device 50 controls the bedding 40 so that it is turned off after bedtime. However, the control device 50 controls the bedding 40 to perform the air blowing operation when a temperature higher than the skin temperature is detected by the bed temperature / humidity detection sensor 43.

  When getting up close, the deep temperature of the sleeper rises slowly. In summer, since the ambient temperature is high, the heat retaining power of the bedding 40 is sufficient, and when heated, it becomes hot and the sleeper is awakened. Therefore, when it is determined that the sleeper has fallen asleep and has approached to wake up based on the detection result of the sleep state detector 30, the control device 50 controls the air conditioner 10 to be operated weakly. As a result, the sleeper can be prevented from feeling hot when waking up.

  FIG. 10 shows the control of the state where the deep temperature has risen too much due to the fact that the person who is going to sleep in the summer is just after returning home and has not been able to take a bath. The skin temperature is higher than normal, and if you go to bed in this state, you will not be able to release heat from your limbs, and you will not be able to fall asleep.

  Therefore, if the skin temperature is close to 37 ° C. or higher than the temperature detected by the detection result of the surface temperature detection sensor 12, the control device 50 controls the air conditioner 10 to a temperature preferred by the sleeper. The bedding 40 is controlled to drive strongly. As a result, the skin temperature can be quickly lowered and heat can be released appropriately. Control from falling asleep to getting up is the same as in FIG.

  FIG. 11 shows control in a state where a person who will go to bed has cooled down by cooling and the skin temperature falls below 30 ° C., for example. In this state, the control device 50 controls the air conditioner 10 to a temperature preferred by the bedridden so as to heat the bedding 40 in a weak operation. As a result, even when there is no time to bathe, the limbs can be warmed to such an extent that heat can be dissipated, and sleep can be promoted. Control from falling asleep to getting up is the same as in FIG.

  In the description of FIGS. 6 to 11, the skin temperature is determined by the air conditioner 10 </ b> A in the living room T, and the sleeper then moves to the bedroom S. However, after entering the bedroom S, the air conditioner 10 may determine the skin temperature.

  As described above, according to the first embodiment, it is possible to realize a pleasant sleep environment control system and a comfortable sleep environment control method that provide a bedroom environment and an in-bed environment according to the state of a sleeping person from before going to bed to wake up. More specifically, instead of controlling according to the season, the state of whether the sleeper is cold or warm before going to bed is determined from the detection result of the sensor, and the air conditioner and the bedding are controlled. It has a configuration. As a result, it is possible to realize a comfortable sleep environment control that allows the user to sleep quickly by controlling the bedroom environment and the bed environment suitable for the sleeping person from the stage before going to bed.

  Furthermore, the apparatus has a configuration in which the state of the sleeping person is determined from the detection result of the sensor and the air conditioner and the bedding are controlled in accordance with the determination result during sleeping and before waking up. As a result, it is possible to realize a comfortable sleep environment control that ensures an appropriate sleep state of the sleeping person and suppresses discomfort when waking up.
