DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air conditioner according to a first embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional example are designated by the same reference numerals, detailed description thereof will be omitted, and only different points will be described.

The temperature detecting device 11, as shown in FIG.
The peripheral skin temperature sensor 12 and the room temperature sensor 13 are covered with a heat insulating material 14, and externally, the peripheral skin temperature detected by the peripheral skin temperature sensor 12 and the room temperature detected by the room temperature sensor 13 are converted into signals, which are used in the air conditioner room. A transmitting unit 16 for transmitting a signal to a receiving unit 15 attached to the front surface of the machine 1, and a belt 1 for attaching these to a human body such as a finger.
It consists of 7.

Further, in FIG. 3, the indoor unit 1 of the air conditioner is shown.
A receiver 15 for receiving a signal transmitted from the temperature detecting device 11 below a blowout grill 6 provided on the front of the front grille, and an air filter 4 for collecting and deodorizing dust behind the front grille 3,
Heat exchanger 5 for heating or cooling the air passing through it
And the cross flow fan 7 is stored.

Reference numeral 18 is an air volume control device for changing the amount of blown air, and based on the data transmitted from the control unit 20 for controlling the rotation speed of the motor 19 by adjusting the voltage and the like, and the data transmitted from the temperature detection device 11. It is composed of a calculation unit 21 for calculating the rising and falling tendency of the skin temperature.

Further, the air volume control device 18 is interlocked with the receiving portion 15, and the receiving portion 15 receives the data signal measured by the temperature detecting device 11 at regular time intervals to grasp the rising and falling tendency of the peripheral skin temperature. , According to the tendency, to keep the strength of the airflow that hits the person living in the room constant, 1 /
The motor 19 is controlled so as to generate a fluctuating wind.

The operation of the air conditioner configured as described above will be described with reference to FIGS. 1 to 4. In general, human peripheral skin temperature fluctuates following changes in room temperature in a quiet and resting state, but when strong stress or tension is exerted, the sympathetic nerves of the autonomic nervous system cause peripheral blood vessel contraction, resulting in blood flow. Is suppressed, and the peripheral skin temperature drops even when the room temperature is constant. On the contrary, I feel drowsiness,
When the level of consciousness is lowered, peripheral blood vessels expand, blood flow increases, and peripheral skin temperature rises.

As the rising and falling tendency of the peripheral skin temperature, the data of the peripheral skin temperature and the room temperature are measured from the temperature detecting device 11 at regular intervals, and the change amount r of the peripheral skin temperature and the change amount R of the room temperature are calculated. To do. For the above reason, the difference between the peripheral skin temperature change amount r and the room temperature change amount R is tension in the A region where r-R << 0, and the sleep state where the consciousness level is lowered in the C region where r-R >> 0. (Fig. 4). The intermediate region between A and C, the B region where r−R≈0 is in a relaxed and normal state, and the peripheral skin temperature variation in the A or C region is changed to the B region to provide a moderately relaxed state. Can be maintained.

Next, the operation of the air conditioner body will be described. First, the front grille 3 is crossed by the cross flow fan 7.
The air sucked from the air passes through the air filter 4 and the heat exchanger 5, and the temperature-controlled air is supplied from the blowout grill 6 into the room.

The air volume control method by the air conditioner of this embodiment will be described with reference to the flow chart of FIG. 5. The data detected by the temperature detecting device 11 at regular intervals is received by the receiving unit 15.
Is received (steps 1 to 2), and the calculation unit 21 calculates a change amount r of the peripheral skin temperature and a change amount R of the room temperature (steps 3 to
5) When r-R >> 0, drowsiness is strong, so a command is sent to the control unit to give a strong air flow (step 6). As a result, the motor 19 is controlled so as to be driven at a high rotation speed, and the person in the living area is stimulated to raise the awakening level.

On the contrary, when r-R << 0, it is judged that the feeling of tension is strong, and the wind of 1 / f fluctuation (frequency of fluctuation fluctuation) is a blowing pattern close to natural wind to relax the occupants. The controller 20 controls the rotation speed of the motor 19 so as to send a wind pattern whose component is inversely proportional to the power spectrum.
(Step 7), the resident who was nervous can approach sedation and approach a relaxed state.

As described above, since the airflow having an appropriate pattern can be continuously blown into the room according to the psychological state and the physiological state of the human being, the comfortable state can be maintained.

Needless to say, as a means for giving the air flow fluctuation, it is possible to control not only the air volume (the rotation of the blower) but also the way the louver swings.

Next, a second embodiment of the air conditioner according to the present invention will be described with reference to the drawings. The first
The same components as those of the embodiment are denoted by the same reference numerals and detailed description thereof will be omitted.

The blood pressure sensor 22, as shown in FIG.
The pressure sensor 23 is covered with a protective material 24, and the pressure sensor 2

Generally, human blood pressure is
The maximum blood pressure is 120 mmHg and the minimum blood pressure is 80 mmHg, which is constant. However, when a strong stress is applied due to a psychological state, peripheral blood vessels contract due to the action of the sympathetic nerves of the autonomic nervous system, and the blood pressure rises. Further, when drowsiness is felt and the level of consciousness is lowered, peripheral blood vessels are expanded and blood pressure is lowered.

As the blood pressure increasing / decreasing tendency, the blood pressure data is measured at regular intervals, and the blood pressure change amount d is calculated. At this time, it can be said that the area A where the blood pressure variation d >> 0 is in tension, and the sleepiness is in the area C where d <0. The intermediate region between A and C and the B region where d≈0 are in a relaxed state (FIG. 9).

The air volume control method by the air conditioner of this embodiment will be described with reference to the flow chart of FIG. 10. The data detected by the blood pressure sensor 22 at regular intervals is received by the receiving unit 2.
5 is received (steps 11 to 12), the operation unit 28 calculates the blood pressure change amount d (steps 13 to 15), and when d >> 0, the 1 / f fluctuation of the air blowing pattern close to the natural wind is obtained. The wind is blown (step 16), and the tense resident can approach sedation and approach a relaxed state.

When d << 0, drowsiness is strong, so a command is sent to the control unit 29 to give a strong air flow (step 17). As a result, the resident who has become sleepy can be kept awake by being stimulated.

As described above, in the same manner as in the first embodiment, the airflow of an appropriate pattern is blown into the room in accordance with the psychological state and physiological state of the human so that the state of d≈0 is achieved. And can maintain a comfortable state.

[0033]

As described above, the air conditioner of the present invention comprises the temperature detecting device for detecting the human peripheral skin temperature and the room temperature, and the receiving portion for receiving the temperature signal transmitted from the temperature detecting device. , It is equipped with an air volume control device that works in conjunction with the receiving unit and can control the air flow pattern according to the rising and falling tendency of human peripheral skin temperature. In other words, 1 / f that can be relaxed when nervous due to the psychological and physiological condition
On the contrary, a strong wind can be blown indoors to give a strong stimulus to the fluctuating wind.

Further, the amount of change in blood pressure is calculated based on a signal from a blood pressure sensor for detecting the blood pressure of a human, and the psychological state and physiological state of the occupant are determined from the tendency of increase and decrease in blood pressure, and then an appropriate air flow is determined. Since it is provided with an air volume control device capable of sending air, the occupants can be kept in a relaxed and comfortable state.

As a result, an appropriate air flow is selected according to the psychological and physiological condition of the human being, that is, the human nervous condition is relieved, and conversely, when the sleepiness is strong, the air current stimulates the psychologically and physiologically. It is possible to create a living environment that brings about various effects.
