DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleeping apparatus for cooling and heating when sleeping.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional sleeping apparatus of this kind.
In the figure, reference numeral 1 denotes an air conditioner, and a target room temperature of the air conditioner 1 is set by a remote controller 2. The remote control device 2 includes a superconducting magnetoresistive element 3 for detecting the activity of the sleeping person's brain, and a control means 7 having a comparing circuit 4, a control command circuit 5, a transmitting circuit 6, and the like.

The comparison circuit 4 determines sleep of the sleeping person, outputs a control signal to a control command circuit 5 and a transmission circuit 6, and the transmission circuit 6 transmits the control signal to the air conditioner 1,
The blowing direction of the air conditioner 1 was controlled (for example, Japanese Patent Application Laid-Open No. 1-127839).

[0004]

When a person changes from an active state to an in-bed state, the metabolic rate of the body decreases, and when the air from the air conditioner directly hits the body, the person feels discomfort due to the cold, and it is quite difficult. 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.

An object of the present invention is to provide a comfortable indoor environment by changing the blowing direction of an air conditioner when a human changes from an active state to a resident state. It is.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an air conditioner installed in a room and a small body movement accompanying a heartbeat and breathing of a sleeper provided in bedding used in the room.
Body movement detecting means for detecting rough body movement such as rolling over and
Heartbeat detected by the body movement detection means , minute body accompanying breathing
And the bed judging means for detecting the bed based on the dynamic, control the blowing direction of the air conditioner by the signal from the the bed judging means
It is provided with a control means for control.

[0007]

According to the present invention, the body movement detecting means detects the body movement of the sleeping person, and the presence determining means detects the presence of the bed based on the signal from the body movement detecting means, and controls the output signal. It sends a signal to the means to change the blowing direction of the air conditioner.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 and FIG. 2, reference numeral 8 denotes a body movement detecting means provided on a mattress 10 of a bed 9 and is connected to an on-bed determining means 11. 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.

The configuration of the occupancy determination means 11 will be described with reference to FIG. 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.

In the above configuration, when a human body is present on the mattress 10, the body motion
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.

Next, the control operation during air conditioning will be described with reference to FIG. 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.

According to the configuration of this embodiment, the blowout direction can be changed upward in the room at the time of detection of the presence of a bed, thereby preventing discomfort due to the air from the air conditioner 17 directly hitting the body of a sleeping person. There is an effect that can be.
