The inconvenience of not being able to sleep is caused. Therefore, in order to maintain the comfort of a sleeping person, the blowing direction of the air conditioner must be changed between the active state and the occupied state. However, in the above-described conventional configuration, the superconducting magnetoresistive element 3 determines whether the sleeping person is sleeping, but cannot determine whether the sleeping person is in the bed. There was a problem that could not be done.

A signal from the occupancy determination unit 11 is sent to a signal determination circuit 13 included in the control unit 12,
Further, it is sent to the blowing direction correction circuit 14. Based on this signal, the blowout direction correction circuit 14 corrects the first blowout direction set in advance by the blowout direction setting circuit 16 by the operation unit 15 and controls the blowout direction of the air conditioner 17.

In the figure, reference numeral 8 denotes a body movement detecting means using a piezoelectric element, which is formed by forming a polymer piezoelectric material such as polyvinylidene fluoride (PVDF) into a thin film and attaching a flexible electrode film on both surfaces to form a tape. It is. Numeral 11 denotes an on-bed determination unit which includes a low-pass filter 18, an amplifier 19, a rectifier 20, an integrator 21, and a comparator 22.

The body is deformed by body movements such as heartbeat, breathing, and turning over, and a voltage is generated by the piezoelectric effect. Then, only a predetermined frequency component of the generated voltage output passes through the low-pass filter 18 and is amplified and rectified.
1 is integrated. FIG. 4 shows an output signal of the integrator 21 in an actual scene. As shown in the figure, there is a large output when coarse body movement occurs such as entering the bed, leaving the bed, turning over, etc., and a low level output due to minute body movements due to human heartbeat and breathing when the person is at rest and at rest. Is obtained, and the output becomes zero when the user is out of bed. That is, as long as a human body is present on the mattress 10 at bedtime, a low-level output can be obtained by at least the above-described minute body movements associated with the heartbeat and respiration of the human body. Utilizing this, the comparator 22 determines that the vehicle is in the occupied state if the output signal of the integrator 21 is within the range of Va and Vb in FIG. Although there are individual differences in the minute body movements associated with the heartbeat and breathing of the human body as described above, Va and Vb can be obtained by subject experiments or the like.

Only when the occupancy detection unit 11 detects the presence of the occupancy, the occupancy determination unit 11 generates a signal. The signal determination circuit 13 determines that the signal is present, and the signal is output to the blowing direction correction circuit 14. Sent to The blowout direction correction circuit 14 changes the blowout direction toward the lower part of the room, which is set in advance by the blowout direction setting circuit 16, by the operation unit 15 to the upward direction. In this way,
As shown in FIG. 2, the blowing direction is corrected in the room from the direction b to the direction a. Of course, if there is no bed detection, the bed determination unit 11 does not send a signal to the signal determination circuit 13 and the blowing direction is not corrected.
The blowing direction set by the blowing direction setting circuit 16 continues until the presence of the floor is detected.
