Embodiment 1
FIG. 1 is an explanatory view showing a usage form of an air conditioning system according to Embodiment 1 of the present invention. FIG. 2 is a block diagram showing a basic configuration of the air conditioning system according to Embodiment 1 of the present invention.

  As shown in FIG. 1, in the air conditioning system 100 according to the first embodiment, an electric device 101 such as the air conditioner 1 and the moisturizing air supply device 2 is installed in the bedroom S. The air conditioner 1 and the moisturizing air supply device 2 have a configuration that allows mutual communication. As a result, the air conditioning system 100 in the first embodiment is formed as a system in which the air conditioner 1 and the moisturizing air supply device 2 operate in conjunction with each other.

  The air conditioner 1 includes an indoor unit and an outdoor unit, and performs an air conditioning operation such as a cooling operation and a heating operation. And as shown in FIG. 2, the air conditioner 1 in this Embodiment 1 is indoor temperature / humidity sensor 10 which detects indoor temperature / humidity, outside temperature / humidity sensor 11 which detects the temperature / humidity of outside air, a person or a floor, A surface temperature detection sensor 12 that measures the surface temperature of a window or the like, a control unit 13 that controls the air conditioning operation based on these sensor outputs, and a communication unit 14 that bidirectionally communicates with the moisturizing air supply device 2 It is done.

  The control unit 13 can adjust the direction of the air flow based on the output of the surface temperature detection sensor 12 and can efficiently perform air conditioning and heating by the blown air flow. The surface temperature detection sensor 12 having such a function determines the position of a person, a window, or the moisturizing air supply device 2 from the detection result of the surface temperature, or sleep to determine the sleep state of the sleeping person It is possible to have the function of performing output as the state determination unit 16.

  The surface temperature detection sensor 12 can use infrared rays, radio waves, etc. as means for performing these outputs, or can also use image analysis with a camera, and measures the movement of a person without contact. be able to.

  The moisturizing air supply device 2 is installed in the same room as the indoor unit. Then, as shown in FIG. 2, the moisturizing air supply device 2 according to the first embodiment determines the indoor temperature / humidity sensor 20 for detecting the indoor temperature / humidity, the sleep state determiner 21, the indoor temperature / humidity sensor 20 and the sleep state determination. The control unit 22 controls the moisturizing operation based on the output of the unit 21 and the communication unit 23 in two-way communication with the air conditioner 1. And the moisturizing air supply machine 2 provided with such a structure blows out high humidity air to a horizontal direction, and humidifies only a user's periphery.

  The sleep state determination unit 21 uses infrared rays, radio waves, and the like, and has the same function as the sleep state determination unit 16 on the air conditioner 1 side. Therefore, in order to determine the sleep state, at least one of the sleep state determiner 21 and the sleep state determiner 16 may be provided. However, since the moisturizing air supply device 2 is disposed at a position closer to the sleeping person, the sleep state determination device 21 can obtain more accurate information than the sleep state determination device 16.

  In the layout shown in FIG. 1, the bedding 102 is installed at a position several tens cm to 1 m away from the moisturizing air supply device 2, and the window 103 is installed in the bedroom S.

  Next, a structure in which the moisturizing air supply device 2 blows high humidity air in the horizontal direction will be described in detail with reference to the drawings. FIG. 3 is an external perspective view of the moisturizing air supply device 2 according to Embodiment 1 of the present invention as viewed obliquely from the front. FIG. 4 is a cross-sectional view of the moisturizing air supply device 2 according to Embodiment 1 of the present invention as viewed from the side.

  First, the configuration of the moisturizing air supply device 2 according to the first embodiment of the present invention will be described in detail using FIGS. 3 and 4. In the drawings, the same reference numerals indicate the same or corresponding parts, and the redundant description thereof is appropriately simplified or omitted.

  In the moisturizing air supply device 2 according to the first embodiment of the present invention, the lower case 31 to which the water supply tank 30 is detachably attached is covered with the water supply tank cover 34 on the rear surfaces of the main body cover 32 and the main body cover 32 forming the outer shell. It is configured. Further, at the upper part of the front surface of the main body cover 32, an air outlet 37 described later is provided.

  At the lower part of the rear surface of the lower case 31, a suction port 35 for taking in room air from the outside of the lower case 31 is formed. Further, at an upper portion of the main body cover 32, an outlet 37 communicating with an outlet 36 described later is formed.

  The main body cover 32 is provided with a power switch 38 and a setting switch 39. By pressing the power switch 38 and pressing the setting switch 39, it is possible to perform input operations such as the operation off time from the start to the end of the humidification operation of the moisturizing air supply device 2 and the setting of the reference humidity. It has become.

  A control substrate 40 is disposed on the front side of the main body cover 32. The control board 40 is operated with a mechanical switch for the power switch 38 and the setting switch 39, a temperature / humidity sensor (not shown) which is a humidity detector for detecting the temperature / humidity of the room air, and the moisturizing air supply device 2. A microcomputer (not shown) to control is mounted.

  Behind the control board 40, a steam generating device 71 which is a humidifier is disposed. The steam generating device 71 has a circular plate shape made of a metal member whose upper side is open, and a heater 72 for steam generation is wound around the outer periphery thereof.

  The water for humidification stored in the water supply tank 30 is supplied to the steam generator 71 from the water supply port 73 via the water supply path 74.

  The water supplied to the steam generating device 71 is heated by energizing the heater 72, and as a result, steam is generated. The steam generation device 71 is not limited to heater heating, and steam may be generated by ultrasonic waves.

  The steam generating apparatus 71 is provided with a steam generating apparatus cover 75 formed of a heat-resistant resin material having a steam vent so as to cover the upper opening. A steam duct 51 formed of a heat-resistant resin material and having a delivery port 36 above the steam generator cover 75 is attached so as to cover the steam generator cover 75.

  The steam generated by the steam generator 71 does not have a wind velocity sufficient to deliver to a position separated from the delivery port 36 of the steam duct 51 by a predetermined distance. Therefore, means for urging the steam to a predetermined wind speed and blowing it out of the delivery port 36 is separately required. Therefore, at the rear of the steam generation device 71, a blower fan 62 is provided which mixes air with the steam and generates a wind for blowing the air from the delivery port 36.

  The blower fan 62 is composed of a fan 62 b and a motor 62 a that rotates the fan 62 b. Then, an air flow is generated by the blower fan 62. The air flow is such that room air is sucked from the suction port 35 and air humidified by the steam generating device 71, which is a humidifier, is blown out from the blowout port 37 into the room. In the first embodiment, the air passage through which the air flow flows is defined as a first air passage.

  A main body cover air passage 76 provided in the main body cover 32 mixes with the steam generated by the steam generation device 71, and urges humidified air from the outlet 36 and blows out air from the outlet 37 into the room. It is a wind path different from the wind path. Specifically, the main body cover air passage 76 is an air passage for guiding the air flow blown out from the delivery port 36 and passing the air flow delivered to a position away from the delivery port 36 by a predetermined distance.

  Then, the wind having passed through the main body cover air path 76 is sent to the movable duct 77 provided on the upper part of the moisturizing air supply device 2 and is further formed below the movable duct 77 on the upper part of the moisturizing air supply device 2 The air is blown forward from the air outlet 78. As a result, the humidified air can be conveyed to a position away from the moisturizing air supply device 2 by a predetermined distance.

  The air outlet 78 is provided with a wind direction adjusting plate 79 for adjusting the direction of the wind, and as shown in FIG. With such a configuration, the humidified air blown out from the air outlet 37 is blown from the top to a position away from the outlet 36 by a predetermined distance by the air passing through the main body cover air passage 76. .

Next, sleep states will be described in detail with reference to FIG.
REM sleep, sleep depth 1, 2, 3 and 4 are shifted in the order of REM sleep, sleep depth 1, 2, 3, 4 in the period from when the person starts sleep onset to sleep, and then sleep depth 3, 2, 1,, The sleep cycle of transitioning to REM sleep is usually repeated approximately every 90 minutes.

  FIG. 5 is an explanatory view showing a change in sleep state from the start of sleep of a person to getting up in Embodiment 1 of the present invention. In FIG. 5, changes in deep body temperature (temperature in the central part of the body (rectal temperature)) considered to be closely related to sleep along with changes in sleep state are represented by dotted lines, and sleep state and body movement are different. The relationship is also illustrated as the height of the vertical bars.

  First, sleep is generally classified into shallow REM sleep and deep non-REM sleep. Sleep is further divided into finer sleep states, and six states of wakefulness, 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 the non-REM sleep into four stages.

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

  The brain waves are named for each frequency band as shown in Table 1, and have different physiological significance. Generally, in healthy individuals, in each state of rest, eye closure and awakening, a large number of alpha waves appear around the occipital region.

  Table 2 is an international classification table of sleep depth determination by electroencephalogram.

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

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

  The sleep depth 1 (stage 1) is said to be the sleeping period, the sleeping period. I am in a dumb condition. The series of α waves recognized at awakening loses the rhythm and gradually flattens. In addition, in the brain wave of sleep depth 1, slow waves of low potential, that is, θ waves appear irregularly, and β waves are mixed. Also, the alpha wave is less than 50% of the awakening period. In the second half of the sleep depth 1, a crescent apex wave (hump or V wave) appears.

  Sleep depth 2 (stage 2) is a state that makes you sleep a little lightly. A sleep spindle and a K complex wave (K complex) appear in the brain wave of sleep depth 2. The sleep spindle wave is a waveform of about 12 Hz to 14 Hz appearing at the top of the head. The K complex wave is a complex wave composed of a biphasic high amplitude slow wave similar to a craniofacial sharp wave followed by a fast wave.

  The sleep depth 3 (stage 3) is a stage in which a brain wave is 2 Hz or less and a slow wave (δ wave) having an inter-peak amplitude of 75 μV or more accounts for 20% or more and less than 50%. It is quite deep sleep, and it can not be perceived unless it is a very strong stimulus.

  The sleep depth 4 (stage 4) is a state in which an electroencephalogram is 2 Hz or less and 50% or more of slow waves (δ waves) of 75 μV or more occupy. The combination of sleep depth 3 and sleep depth 4 is called slow wave sleep. The sleep stages from the sleep depth 1 to the 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 brain waves (feature 2) Rapid eye movement (REM) appears (feature 3) Antigravity muscle tone reduction maintaining body posture occurs And, I often say that I was dreaming when I was stimulated to wake up during this REM sleep.

  Next, the operation of the air conditioning system according to Embodiment 1 of the present invention will be described in detail using FIGS. 6 and 7. FIG. 6 is a flowchart showing the control operation of the air conditioning system according to Embodiment 1 of the present invention. Furthermore, FIG. 7 is an explanatory view showing an example of a detection result by the surface temperature detection sensor 12 according to the first embodiment of the present invention.

  In step S 1, the air conditioner 1 is in a heating operation by remote control operation, and the moisturizing air supply device 2 starts a humidification operation by pressing the power switch 38. A timer time is selected and a series of driving is started.

  In step S <b> 2, the control unit 13 in the air conditioner 1 acquires the temperature distribution of the bedroom S measured by the surface temperature detection sensor 12. As shown in FIG. 7, when sleeping in winter, generally, the room temperature is 15 to 20 ° C., the temperature Tm around the window is 10 ° C. or less, and the temperature around a person or moisturizing air feeder 2 is a heating element So it is higher than room temperature. Therefore, the control unit 13 can specify the position of the window, the position of the sleeping person, and the position of the moisturizing air supply device 2 from the temperature distribution measured by the surface temperature detection sensor 12. Then, the process proceeds to step S3.

  In step S3, the control unit 13 obtains the temperature and humidity of the room measured by the room temperature and humidity sensor 10, and calculates the dew point temperature Tr from the relationship with the set humidity of the air conditioner 1 and the moisturizing air feeder 2. . At this time, the air conditioner 1 and the moisturizing air supply device 2 can share information by mutual communication between the communication unit 14 in the air conditioner 1 and the communication unit 23 in the moisturizing air supply device 2. Therefore, the calculation of the dew point temperature Tr may be performed by either the control unit 13 in the air conditioner 1 or the control unit 22 in the moisturizing air supply device 2. Then, the process proceeds to step S4.

  In step S4, the control unit 13 performs condensation determination based on the surface temperature Tm of the window and the dew point temperature Tr. Specifically, in the case where the surface temperature Tm of the window ≦ the dew point temperature Tr, the control unit 13 determines that condensation is present or condensation is likely to occur, and the process proceeds to step S5. On the other hand, when the surface temperature Tm of the window> the dew point temperature Tr, the control unit 13 determines that there is no dew condensation, and proceeds to step S8.

  When the process proceeds to step S5, the control unit 13 in the air conditioner 1 or the control unit 22 in the moisturizing air supply device 2 controls the sleep state determination unit 16 in the air conditioner 1 or the moisturizing air supply device 2. The sleep state is determined from the sleep state signal based on the size or body temperature of the body movement as shown in FIG. 5 acquired by the sleep state determiner 21, and the communication unit 14 and the communication unit 23 communicate with each other ,Share information.

  In the first embodiment, the sleep state determination unit 16 and the sleep state determination unit 21 use as a sleep state signal a shallow sleep signal indicating that the user has entered shallow sleep (REM sleep, sleep depths 1 and 2); It shall be distinguished from a deep sleep signal indicating that deep sleep has been entered. Note that the size of body motion or deep body temperature may be output from the sleep state determination units 16 and 21, and the control units 13 and 22 may be configured to generate a sleep state signal.

  Before and after REM sleep, it is known that body movement increases. Therefore, when the body movement increases, the sleep state determiners 16 and 21 determine that the sleep is shallow. When the determination result is deep sleep, the process proceeds to step S6, and when the determination result is shallow sleep, the process proceeds to step S7.

  In the case of shallow sleep, since it is sensitive to changes in the thermal environment, if the air is blown directly to the sleeping person, halfway awakening occurs. On the other hand, during deep sleep, the sensitivity to the change of the sleep environment and the stimulation of the air blowing is low, and the possibility of halfway awakening is low.

  Therefore, when the process proceeds to step S6, the control unit 13 performs the condensation removal operation. Here, the condensation removing operation is an operation of removing or suppressing condensation by blowing dehumidified air or warm air higher than the temperature Tm to the window position by the control unit 13 in the air conditioner 1. . Then, the process proceeds to step S11.

  On the other hand, when the process proceeds to step S7, the condensation removal operation (person protection) by the air conditioner 1 or the humidification operation by the moisturizing air supply device 2 is temporarily stopped. Here, the condensation removal operation (person protection) is an operation in which the dehumidified air by the air conditioner 1 or the warm air is blown away from the position of the person. Then, the process proceeds to step S11.

  When it progresses to step S8 from previous step S4 by judging that there is no dew condensation, the control part 13 in the air conditioner 1 determines the result of the sleep state determination device 16. Then, when the sleep state is deep sleep, the control unit 13 proceeds to step S9 and performs the set normal driving, and when the sleep state is shallow sleep, the process proceeds to step S10 and the human position detection result. Based on, drive people. Then, the process proceeds to step S11.

When the process proceeds to step S11, the control unit 13 determines which one of the following three conditions is met.
(Condition 1) Whether the power switch 38 was pressed and the power was turned off (Condition 2) Whether the off timer time was reached after humidification operation (off timer operation) was started (condition 3) whether the water amount is zero

  If the control unit 13 determines that one of the conditions is met, the process proceeds to step S12. If not, the process returns to step S2, and the process is repeated.

  When the process proceeds to step S12, the control unit 22 in the moisturizing air supply device 2 stops the energization of the heater 72, stops the energization of the blower fan 62, and stops the humidification operation. On the other hand, the control unit 13 in the air conditioner 1 continues the operation and stops the operation when the sleeping person is stopped by the remote control or the like.

  As described above, according to the air conditioning system of the first embodiment, the presence or absence of dew condensation is determined based on the indoor temperature / humidity detection result, and the sleep state of the sleeper is determined, and dew condensation is determined according to the determination result. The air conditioner and the moisturizing air supply can be controlled to suppress or eliminate the air conditioner. As a result, it is possible to provide a healthy and easy-to-use sleep environment without generation of mold and without disturbing sleep of the sleeping person.

  In addition, in Embodiment 1 mentioned above, although it was set as the system using the moisturizing air supply machine 2 humidified locally, the same effect is acquired also when the system which humidifies the whole room is employ | adopted. Although it is difficult to suppress condensation if the window is in the vicinity, local humidification is combined, but as in the first embodiment, an air conditioner and a moisturizing air supply are combined based on the result of the temperature and humidity detection. Condensation can be reduced by controlling the

Similar to the assumption in the first embodiment, the room temperature is 15 to 20 ° C., and the temperature Tm around the window is 10 ° C. or less.

  In such a case, the temperature is higher than room temperature because a person is a heating element, and the control unit 22 in the moisturizing air supply device 2 determines the position of the window from the temperature distribution measured by the surface temperature detection sensor provided in the moisturizing air supply device 2 , Position of the person can be identified.

  At this time, the control unit 22 carries out the condensation removal operation by stopping energization of the heater 72, avoiding the position of a person, and blowing air only to the position of the window. The moisturizing air supply device 2 is closer to the window to be blown than the air conditioner 1 and can locally blow air.
