Description

  The present invention relates to an air conditioning control device that controls the operation of air conditioning equipment to adjust room temperature and the like.

  Conventionally, in sleep in summer, air conditioning equipment such as cooling is often operated so as to eliminate the heat and easily fall asleep. In this case, if the air-conditioning equipment is operated at all times until the wake-up time, the sleep environment of the sleeper may be impaired by waking up at dawn or becoming heavy when waking up. In many cases, the air conditioning is stopped after a predetermined time by setting an off timer. However, in the summer, when the air conditioning is stopped, the room temperature rises in a short time. In this case, it seems that it is sufficient to set the off timer and go to sleep again, but when the off timer expires after re-sleeping and the air conditioning stops, the temperature in the room rises, and there are very many cases that awaken halfway again .

  As a means for solving the above problem, for example, in Patent Document 1, in the “sleeping cooling operation mode” at the time of going to bed, the air conditioner is not maintained at a constant temperature throughout the sleep period but is maintained during the sleep period. A means for intermittently raising the set temperature of 1 to 4 ° C. is disclosed. That is, by alternately repeating the section in which the air conditioner is operated at the set temperature and the section in which the air conditioner is operated at a temperature higher than the set temperature, it is possible to prevent awakening midway due to heat, coldness, or the like.

JP 05-187679 A

  By the way, human deep body temperature shows a circadian rhythm with a cycle of 24 hours. As shown in FIG. 4 (a), the deep body temperature is generally the lowest at around 4-5am, but is highest at around 7-8pm, although there are individual differences. In addition, changes in deep body temperature are strongly related to the onset of sleep, and the degree of arousal is high near the maximum body temperature, so that even if you try to sleep, you can hardly sleep. After 9 pm, the deep body temperature gradually decreases and decreases more rapidly with the start of sleep.

  However, in the above-described conventional example, the set temperature of the air conditioner is changed regardless of the above-described change in the deep body temperature. Therefore, the body temperature cannot be adjusted due to the influence of the set temperature of the air conditioner during the period when the deep body temperature is low or high. There is a case. For example, at around 4-5 am when the deep body temperature is the lowest, it is desirable that the set temperature of the air conditioner is not too low in order to prevent falling asleep, but in the conventional example, the set temperature of the air conditioner is low during this period. There is a fear. Therefore, there has been a problem that a high-quality sleep environment according to changes in deep body temperature cannot be obtained.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an air conditioning control device capable of obtaining a high quality sleep environment according to a change in the deep body temperature of a user.

  In order to achieve the above object, the invention of claim 1 is an air conditioning control device for controlling an air conditioner installed in a room, and is a mode input for receiving an input for setting a sleep mode in which a user goes to sleep.

If it exceeds, it has the operation control part which starts the driving | operation of an air conditioning apparatus, It is characterized by the above-mentioned.

  According to a second aspect of the present invention, in the first aspect of the present invention, a signal is output between the bed table and the mattress placed on the bed table in response to vibration caused by the user turning over on the mattress. A turnover frequency detection unit that detects a user's turnover frequency according to a signal output from the vibration sensor, and a user's sleep time is estimated according to a detection result of the turnover frequency in the turnover frequency detection unit The threshold setting unit estimates a change in the user's deep body temperature from the time estimated by the sleep estimation unit in the sleep mode, and sets a room temperature threshold for each predetermined time according to the estimation result. It is characterized by doing.

  According to a third aspect of the present invention, in the second aspect of the invention, the threshold setting unit is configured to reduce the turnover frequency when the turnover frequency detected by the turnover frequency detection unit during operation of the air conditioner is equal to or greater than a predetermined value. It is characterized by changing the threshold value of room temperature.

  According to the first aspect of the present invention, the room temperature threshold can be changed according to the elapsed time from the time when the sleep mode is set in consideration of the change in the deep body temperature. There is no room temperature control that ignores changes in deep body temperature such as lowering the temperature. Therefore, it is possible to obtain a good sleep environment according to changes in deep body temperature.

  According to the invention of claim 2, the time closer to the user's actual sleep time compared to the case where the operation of the air conditioner is controlled by the elapsed time from the time when the input for setting the sleep mode is accepted. It is possible to control the operation of the air conditioner in accordance with the above.

  According to the invention of claim 3, it is possible to cope with each user by controlling the operation of the air conditioner in consideration of the user's turnover frequency in addition to the control of the operation of the air conditioner according to the change in the deep body temperature. A better quality sleep environment can be obtained.

(Embodiment 1)
Hereinafter, Embodiment 1 of an air-conditioning control apparatus according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the present embodiment controls the operation of an air conditioner D arranged in a room provided with a bed base A and a mattress B on which a user C lies down and goes to sleep. A mode input receiving unit 1 that receives an input for setting a sleeping mode in which the person C goes to bed, a time detecting unit 2 that detects a time when an input for setting the sleeping mode is received by the mode input receiving unit 1, and a room temperature. A change in the deep body temperature of the user C is estimated from the room temperature detection unit 3 to be detected and the time detected by the time detection unit 2 in the sleep mode, and a room temperature threshold is set for each predetermined time according to the estimation result. The threshold setting unit 4 and an operation control unit 5 that starts the operation of the air conditioner D when the room temperature detected by the room temperature detection unit 3 exceeds the threshold set by the threshold setting unit 4.

  The mode input reception unit 1 includes, for example, a push button, and transmits a start signal to the time detection unit 2 to notify that the sleep mode for controlling the operation of the air conditioner D when the user C sleeps is started by performing a push operation. To do. When the time detection unit 2 receives the start signal from the mode input reception unit 1, the time detection unit 2 detects the time set in the sleep mode in the mode input reception unit 1 from the time measurement unit 20 that measures the current time, and obtains the time information. The included time signal is transmitted to the threshold setting unit 4.

  The room temperature detection unit 3 converts a temperature sensor 30 disposed near the head of the user C on the bed table A and an analog signal including room temperature information output from the temperature sensor 30 into a digital room temperature signal as A / It comprises a conversion unit 31 that performs D conversion and transmits it to the operation control unit 5. The temperature sensor 30 is composed of, for example, a thermistor or a thermocouple. When receiving a command signal from the operation control unit 5 described later, the conversion unit 31 transmits a room temperature signal including room temperature information detected by the temperature sensor 30 to the operation control unit 5 at regular intervals. The temperature sensor 30 is preferably disposed in the vicinity of the head of the user C in order to detect a temperature as close as possible to the temperature experienced by the user C, but may be disposed in another location. .

  The threshold setting unit 4 stores in advance data on changes in deep body temperature as shown in FIG. In this embodiment, data of changes in deep body temperature, which are generally recognized as sleep research data, are adopted (Japan Sleep Improvement Council, “Basic Course Sleep Improvement Studies”, 1st Edition, Yuma Co., Ltd.) (See Shobo, February 10, 2008, p. 103, FIG. 1). Of course, a change in the deep body temperature of the user C itself may be measured in advance and the data may be stored. In the threshold setting unit 4, when time information is obtained from the time detection unit 2, first, a first threshold value for room temperature is set based on the deep body temperature data at that time, and a threshold signal including the first threshold information is operated. It transmits to the control part 5. Thereafter, the first threshold value is changed based on the deep body temperature data every predetermined time, and a threshold signal including the changed first threshold information is transmitted to the operation control unit 5.

  For example, as shown in FIG. 4B, when the sleeping mode is set at 11:00 pm, the first threshold is set based on the deep body temperature t1 at 11:00 pm, and the morning after 6 hours has elapsed from the set time. At 5 o'clock, the first threshold is set based on the deep body temperature t2. In addition, when the sleep mode is set at 1 am, the first threshold is set based on the deep body temperature t3 at 1 am, and at 7 am 6 hours after the set time, the first threshold is set based on the deep body temperature t4. A threshold value of 1 is set. As described above, even if the elapsed time is the same, the change in the deep body temperature varies depending on the set time of the sleeping mode, but the first threshold value can be set corresponding to the change in the deep body temperature.

  Operation control part 5 consists of microcomputers, for example, and controls the start and stop of operation of air-conditioning equipment D by transmitting a control signal to air-conditioning equipment D using infrared rays. When the operation control unit 5 receives the threshold signal from the threshold setting unit 4, the operation control unit 5 transmits a command signal instructing to transmit the room temperature signal to the conversion unit 31 at regular intervals. And the control signal which compares the room temperature detected by the room temperature detection part 3 with the 1st threshold value of the room temperature set by the threshold value setting part 4, and starts the driving | operation of the air-conditioning equipment D, when room temperature exceeds a 1st threshold value Is transmitted to the air conditioner D by infrared rays. In addition, in the operation control part 5, the 2nd threshold value of the room temperature considered that the user C feels cold when the temperature is lower than this is separately set apart from the first threshold value. A control signal for stopping the operation of the air conditioner D is transmitted to the air conditioner D by infrared rays.

  As described above, since the first threshold value of the room temperature can be changed according to the elapsed time from the time when the sleep mode is set in consideration of the change in the deep body temperature, for example, the setting of the air conditioner D in the period when the deep body temperature is low There is no room temperature control that ignores changes in deep body temperature such as lowering the temperature. Therefore, it is possible to obtain a good sleep environment according to changes in deep body temperature.

  In the present embodiment, in consideration of the point that the temperature sensor 30 detects the room temperature in the vicinity of the head of the user C and the point that the user C is easy to operate, the box-shaped apparatus main body that accommodates each part is used as the bed. It is desirable to arrange in the vicinity of the head of the user C on the table A. Of course, it goes without saying that it may be arranged in another place.

(Embodiment 2)
Hereinafter, Embodiment 2 of the air-conditioning control apparatus according to the present invention will be described with reference to the drawings. Since the basic configuration of the present embodiment is the same as that of the first embodiment, common portions are denoted by the same reference numerals and description thereof is omitted. In the first embodiment, the first threshold value of the room temperature is set according to the elapsed time from the time when the input for setting the sleeping mode is received by the mode input receiving unit 1. However, the user does not fall asleep immediately after the sleep mode is set, and there may be a difference between the set time of the sleep mode and the actual sleep time of the user.

  Therefore, in the present embodiment, as shown in FIG. 2, signals 1 to 1 are arranged between the bed table A and the mattress B and output signals corresponding to vibrations caused by body movement such as turning over the user C. A vibration sensor 60 having a plurality of sensor elements (not shown), a turnover frequency detection unit 6 that detects a turnover frequency of the user C according to a signal output from the vibration sensor 60, and a turnover in the turnover frequency detection unit 6 And a sleep onset estimating unit 7 for estimating the sleep onset time of the user C according to the frequency detection result.

  The turnover frequency detection unit 6 detects a time series distribution of body motion that is an index of the turnover frequency from the signal output from the vibration sensor 60. The sensor element of the vibration sensor 60 is composed of a piezoelectric element made of a polymer piezoelectric material such as PVDF (polyvinylidene fluoride). The sleep onset estimating unit 7 detects the muscle relaxation of the user C in the sleep period from the time series distribution of the body motion obtained by the turnover frequency detecting unit 6, and estimates the sleep onset time. In this embodiment, when the body movement of the user C is continuously stopped for 5 to 10 minutes, it is assumed that the user C has relaxed muscles, and the time point is estimated as the sleep time. The threshold value setting unit 4 sets the first threshold value of room temperature for each predetermined time in the same manner as in the first embodiment, based on the elapsed time from the sleep time estimated by the sleep sleep estimation unit 7.

  As described above, compared with the case where the operation of the air conditioner D is controlled by the elapsed time from the time when the input for setting the sleep mode is received, the time closer to the user's actual sleep time is set. The operation of the air conditioner D can be controlled.

  By the way, in this embodiment, although the 1st threshold value of room temperature is set according to the change of deep body temperature, the data of the deep body temperature to refer are the data of the change of the deep body temperature generally recognized as sleep research data. is there. Therefore, the user C cannot cope with a change in the deep body temperature that varies depending on the individual, and the user C may feel hot at the first threshold value of the set room temperature. Further, even when referring to the data of the deep body temperature of the user C measured in advance, the user C may feel hot at the first threshold value of the set room temperature depending on the physical condition of the user C and the like.

  Therefore, as shown in FIG. 3, the threshold setting unit 4 refers to the time series distribution of body motion detected by the turnover frequency detection unit 6, and for example, when the number of occurrences of body motion in a certain period exceeds a predetermined number of times. Alternatively, the first threshold value of the room temperature may be decreased in increments of 0.5 ° C. so as to reduce the turnover frequency. In this case, by controlling the operation of the air conditioner D in consideration of the turnover frequency, which is an index of the hotness felt by the user C, in addition to the control of the operation of the air conditioner D according to the change in the deep body temperature, A better quality sleep environment corresponding to each person C can be obtained.
