Abstract

PURPOSE:To ensure the pleasant sleep by controlling the environmental temperature via an environmental temperature control means so that the deterioration of a bodily temperature control function is compensated in a REM sleep state. CONSTITUTION:An environmental temperature controller contains a sleeping state detecting means 2 which decides the REM sleep or the NREM sleep based on the output of an organism signal detecting sensor like a heart beat sensor 1a, a body movement sensors 1b, etc., and an environmental temperature control means 3 which controls an air conditioning means 4 based on a state detecting signal VR delivered from the means 2 so that the environmental temperature is set at a prescribed level. Thus the environmental temperature is controlled. Furthermore a temperature sensor 5 detects the actual environmental tempera ture for feedback control. Then the means 4 compensates the deterioration of a bodily temperature control function in a REM sleep state to maintain the health.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an environmental temperature control device that optimally controls the environmental temperature during sleep.

BACKGROUND ART 1 Conventionally, this type of environmental temperature control device optimally controls the environmental temperature during sleep. There was one that could be set to create a comfortable sleeping environment. For example, air conditioners are equipped with a so-called "sleep timer," which is set up after a certain period of time (1~
A control method is used in which the heating and cooling intensity is lowered after 2 hours. There are also systems that turn off the air conditioner or heating after a certain period of time, and then turn it on automatically at a set time the next morning. However, in such a conventional example, since the environmental temperature is set while ignoring the physiological state of humans during sleep, there is a problem that comfortable sleep may be disturbed. In other words, the physiological state of humans during sleep is not uniform, and as shown in Figure 2 (a), the sleep state changes periodically, and during REM sleep, the function of the autonomic nervous system is disrupted. , fluctuations in heart rate, breathing rate, etc. not only increase, but also the body temperature regulation function decreases.

Therefore, if you ignore this REM sleep and change the environmental temperature a certain period of time after going to sleep, as in the conventional example, the perceived temperature will change (too cold or too hot), which will disturb comfortable sleep. .

[Objective of the Invention 1 The present invention has been made in view of the above points, and its purpose is to provide a comfortable sleep by keeping the sensible temperature constant during sleep, and to provide a body temperature regulating function. An object of the present invention is to provide an environmental temperature control device that can compensate for the decrease in temperature and promote health maintenance.

[Disclosure 1 of the Invention (Configuration) The present invention provides sleep state detection means for detecting REMI sleep or NREM sleep based on the output of a biological signal detection sensor, and a state detection signal output from the sleep state detection means. and an environmental temperature control means that controls the air conditioning equipment so that the environmental temperature reaches a predetermined temperature, and the environmental temperature control means

By controlling the environmental temperature so that the body's body temperature regulation function declines, it is possible to maintain a comfortable temperature while sleeping, thereby compensating for the decline in body temperature regulation function and promoting health maintenance. The present invention provides an environmental temperature control device.

In the figure, a temperature sensor 5 is a temperature detection means for detecting the actual environmental temperature and performing feedback control so that the environmental temperature becomes a predetermined temperature. In addition, in the embodiment, the determination of the REM sleep period by the sleep state detection means 2 is as follows:
Increased variance of heart rate per unit time observed during REM sleep, REMII! It is detected by the increased frequency of body movements seen before and after sleep, and although sleep depth changes during periods other than REM sleep, it is considered to be NREM sleep and REMI! The sleep signal ■R is not output. Further, as the heating and cooling means 4, an air conditioner that adjusts the indoor temperature, an electric bed sheet that adjusts the temperature of the bed, a sleep pillow that adjusts the temperature of the pillow, etc. can be considered, and the temperature sensor 5 corresponds to the various heating and cooling means 4. Needless to say, each is provided separately.

The operation of the embodiment will be described below. Now, Figure 2 (

During M sleep, a REM sleep signal is sent from the sleep state detection means 2, and when this REM detection signal VR is obtained, the environmental temperature control means 3 changes the environmental temperature to NREM.

The air conditioner/heater is controlled so that the optimum environmental temperature is set according to the sleeping state. Next, when transitioning to NREM sleep, the environmental temperature is set to the set temperature Ts for NREM sleep, so that the optimal environmental temperature for obtaining comfortable sleep can always be achieved. FIG. 2(b) shows the environmental temperature change (room temperature change) during heating, and FIG. 2(c) shows the environmental temperature change (room temperature change) during cooling.

is about 35°C (winter) to 32°C (early spring, late autumn), and the air conditioner's set temperature Tl1l is set to be low.

As described above, in the embodiment, since the NREM sleep state continues for a while after falling asleep, the environmental temperature is set to Ts, and then when the transition to REM sleep occurs, the environmental temperature is immediately set to TR. , it is possible to achieve the optimal environmental temperature according to the sleeping state, and to optimally control the environmental temperature even when the sleeping state changes thereafter, keeping the perceived temperature constant during sleep to obtain a comfortable sleep. Now you can REM @ sleep temperature ip! It is now possible to compensate for the decline in regulatory function and promote health maintenance.

This device controls the environmental temperature to compensate for the decline in body temperature regulation during sleep, so you can maintain a constant sensible temperature while sleeping and get a comfortable night's sleep.
Moreover, it has the effect of compensating for the decline in body temperature regulation and promoting health maintenance.
