Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of a seat air conditioning control system according to the present invention when applied to a car. FIG. 2 is a perspective view of a seat portion in the embodiment. FIG. 3 is a correlation diagram between the feeling of perspiration and the humidity of the seat in the embodiment.

That is, in FIG. 1, a cooling device 22 provided in an engine room 21 is provided inside a vehicle body 20.
And a blower 25 for blowing air heat-exchanged in the cooling device to a seat 1 as a seat portion for a person to be seated, which is provided in a vehicle interior 24 as an occupant's living space; An air duct 36 and the like are provided as a plurality of air paths for sending the exchanged air to the seat 1. Further, an opening / closing valve (not shown) is provided in each of the blowout portions of the air duct 36 so that the air from the cooling device 22 can be controlled for each seat. As shown in FIG. 2, the seat 1 provided in the vehicle interior 24 includes a seat portion 1a, a backrest portion 1b, a side portion 1c on which no person sits, and the like, and is provided on the surface of the seat portion 1a. Is a temperature for detecting a body temperature, which is a kind of physiological state, of a person seated on the seat 1 at a position substantially parallel to the plurality of air outlets 2 for blowing cold air or hot air or the like. Sensor 7 and humidity sensor 8 for detecting a sweating state which is a kind of physiological state
However, a plurality of them are arranged at substantially the same place. The temperature sensor 7 is also provided on the side surface portion 1c.

Further, inside the seat 1, a control circuit 9 as a control unit, a blower 5 for blowing cool air or hot air from the blowout hole 2, and a blower connecting the blower 5 and the blowout hole 2 are provided. A path 3, a heater 4 for heating the blown air, and the like are provided. The blower 5, the heater 4, and the like are arranged inside the seat 1 in a united manner as a hot air unit 10. Further, a suction filter 6 is provided on a side surface of the hot air unit 10,
A terminal of the above-mentioned air duct 36 is connected to a half portion thereof, so that cool air is blown in.

The control circuit 9 includes a blower 5, a heater 4,
The temperature sensor 7 and the humidity sensor 8 are electrically connected to the cooling device 22 and the blower device 25 described with reference to FIG. The storage element 13 is built in. Further, as the temperature sensor 7, a small thermistor is used. As the humidity sensor 8, an electric resistance type sensor in which a thin film or fine powder of a semiconductor polymer is applied by vapor deposition on a ceramic substrate, or the humidity of a nylon ribbon is used. Sensors using expansion and contraction due to change are used.
Further, the humidity sensor 8 is configured to be able to detect a humidity change corresponding to a sweating state of a person sitting on the seat 1 and a humidity included in the seat 1 itself. It should be noted that the other seats 1 'have the same configuration,
There is no dedicated control circuit for the seat 1 ', and it is electrically connected to the control circuit 9 built in the seat 1.

Next, the operation of the above embodiment will be described with reference to FIGS. 1, 2 and 3.

First, in FIG. 1, when a person starts an engine (not shown) in a car, the temperature sensor 7 and the humidity sensor 8 start detecting operation by the operation of the control circuit 9. Therefore, among the plurality of temperature sensors 7 arranged on the seating portion 1a of the seat 1, a change in the detected temperature of the specific temperature sensor 7 is determined by a predetermined criterion (that is, 5 minutes after the detected temperature starts to change). (The temperature rises by 1 ° C. or more and reaches 30 ° C. or more in 10 minutes), the control circuit 9 receiving the signal determines that a person is seated on the seat 1. Further, the control circuit 9 also detects that a person is seated at a position where the temperature sensor 7 which has detected the highest temperature among the specific temperature sensors 7 is provided.
In other words, it is possible to determine the seating position where the occupant is. Note that, when the seat temperature is equal to or higher than 30 ° C., for example, in summer, when the cooling device 22 or the like is operated, a change in temperature is one of the seated portion and the non-seated portion. By utilizing the difference between the side portions 1c of the seats, the cooling device 22 and the like are operated to
Even after a lapse of minutes, the temperature rises by 1 ° C. or more in 5 minutes after the temperature sensor 7 disposed on the seating portion 1a detects 30 ° C. or more and the detected temperature of the temperature sensor 7 starts to change. If so, it is determined that a person is seated at the position where the temperature sensor 7 is provided. As described above, since it is necessary to detect the temperature of the non-seat portion, the temperature sensor 7 is also provided on the side surface portion 1c at a position where the user cannot sit on the side surface of the seat 1 as described above. In addition, the temperature sensor 7 provided in the seating portion 1a
And a temperature sensor 7 disposed on the side surface portion 1c, and in a substantially similar manner, whether the temperature has risen by 1 ° C. or more in 5 minutes or not Can be determined whether there is a person or an object is placed in That is, if it is rising, it is determined that a person is seated, otherwise it is determined that an object is placed. Thus, when the cooling device 22 and the like can be controlled on the front side and the rear side of the seat, the seated position of the person is known, so that useless energy can be saved. Also, in a car, there is a mechanism that acts as a cushion by activating an airbag in order to ensure the safety of a passenger in the event of a collision. At this time, if the seating position is known, the airbag can be operated accurately.

The fact that the temperature sensor 7 and the humidity sensor 8 provided on the seat 1 are useful for detecting the physiological state of a person sitting on the seat 1 will be described based on experimental data.

That is, an experiment was repeated in which the subject was seated in the seat 1 of the car 24 in an awake state, and had to report on the feeling of warmth, coolness, sweating, comfort, etc. while measuring the skin temperature of each part of the subject. As a result, it was found that the temperature of the subject's back and hips correlated well with the subject's thermal sensation.

On the other hand, as for the humidity, as shown in FIG. 3, when the humidity of the back and the hip became 65% RT or more, the subject reported sweating. Therefore, the seating position of the person sitting in the seat 1 is detected by the temperature sensor 7 as described above, and therefore, the humidity sensor 8 at that specific position (the humidity sensor 8 is located at the same position as the temperature sensor 7). It can be said that the detection data is hardly affected by the humidity of the vehicle interior 24 and correlates well with the sweating state of the person sitting on the seat 1.

From the above, for example, discomfort due to heat involves perspiration, so that it can be detected by the humidity sensor 8 disposed on the seat 1, and discomfort due to cold is disposed on the seat 1. The temperature can be detected by the temperature sensor 7. This is completely different from the conventional method of detecting the room temperature and controlling the air conditioner so as to approach the target value. That is,
The temperature sensor 7 and the humidity sensor 8 provided on the seat 1 are useful for detecting the physiological state of a person sitting on the seat 1.

Next, a specific control method of the cooling device 22, the blower 25, the heater 4, the blower 5 and the like as an air conditioner for adjusting environmental conditions in and around the seat portion will be described. .

First, referring to FIG. 2, a description will be given of a control method performed on a person sitting on the seat 1 with a focus on the humidity sensor 8.

That is, after the control circuit 9 detects that a person is seated on the seat 1, as described above, the data detected by the humidity sensor 8 at the place where the person is seated and the storage element 13 as described above. The control circuit 9 compares the comfortable physiological information on the state that the person feels comfortable, which is determined based on the experimental results and stored in advance. Therefore,
If the value of the detection data is 65% RH or more, only the blower 5 built in the seat 1 provided with the specific humidity sensor 8 that detects 65% RH or more by the electric signal from the control circuit 9 Starts its operation, and blows air to the person through the blowing hole 2 to suppress perspiration. As a result, when the detection data of the humidity sensor 8 becomes equal to or lower than the predetermined humidity, the blower 5 stops.

If the temperature of the air blown by the air for suppressing the above-mentioned perspiration exceeds 28 ° C., the body temperature rises and conversely, the perspiration is promoted. Then, the temperature of the wind blown out from the blow-out hole 2 is detected by the temperature sensor 7 in a part where no person is detected by the temperature sensor 7, and when the temperature exceeds 28 ° C., in addition to the blower 5, The cooling device 22 and the blowing device 25 described in 1 start operating. As a result, the temperature of the wind becomes sufficiently low and the cool air is blown by the blower 5, so that sweating is eliminated.
When the cooling device 22 and the blower 25 are operated, the seat 1
Only the open / close valve (not shown) provided at the blow-out portion of the air duct 36 connected to the air conditioner is controlled to open.

In this way, the cool air blown out by the blower 25 to the suction filter 6 of the seat 1 through the blower duct 36 is sucked from the suction filter 6 by the blower 5 in the seat 1 shown in FIG. The air is blown out from the blowout hole 2 through the air passage 3. Thereby, it is possible to prevent the sweating from being stopped promptly and to be uncomfortable, and also to prevent a cold due to excessive sweating or a dehydration due to the excessive rise in body temperature.

Next, with reference to FIG. 2, a method of controlling a person sitting on the seat 1 with the temperature sensor 7 at the center will be described.

That is, it is known from the above-mentioned experiment that data detected by the temperature sensor 7 in a place where a person is seated is hot when the temperature is 36 ° C. or higher. Activate. Then, the air blowing is continued until the temperature reaches a comfortable temperature range of 33 ° C. to 34 ° C. stored in advance in the storage element 13 as the comfortable physiological information on the state in which the person feels comfortable. If the temperature is as high as 37 ° C. and does not fall within the above-mentioned comfortable temperature range even if a predetermined time stored in advance by the timer function provided in the control circuit 9 has passed, cooling is performed. Of course, the device 22 and the like may be operated.

On the other hand, even if a predetermined time (for example, 10 minutes) stored in advance by a timer function provided in the control circuit 9 has elapsed since the person was seated, the place where the person is seated The temperature detected by the temperature sensor 7 at 29 is 29
If the temperature does not reach the comfortable temperature range of 33 ° C. to 34 ° C. stored in advance in the storage element 13 as the comfortable physiological information regarding the state in which a person feels comfortable while the temperature is low, such as the temperature of the control circuit. The heater 4
By operating the blower 5 and the like to blow out warm air from the blowout hole 2, it is possible to take prompt measures.

By the way, the above description is about the control when a person is seated on the seat 1. Next, a case where no person is seated on the seat 1 (or the seat 1 ') will be described. A description will now be given of the in-seat humidity management for controlling the humidity state of the seat 1 (or the seat 1 ').

That is, for example, when the state of the seat 1 'is changed from a state where a person is seated to a state where the person is away (ie, a state where the person gets off the car), the temperature sensor 7 disposed on the seat 1' operates. , Detects that a person has left,
Normally, control operations such as air blowing for a person who has been seated up to now are temporarily stopped by a command from the control circuit 9. However, within a predetermined time immediately after the person has left the seat, the detection data from the humidity sensor 8 disposed at
When the humidity exceeds% RH, the humidity is considerably high. Therefore, in order to make the next occupant comfortable, the blower 5 starts operating by an electric signal from the control circuit 9 and the humidity sensor 8 is operated. The operation is continued until the detection data by the data becomes 50%. At this time, the cooling device 22 and the heater 4 are also operated, so that the dehumidified cooling air generated by the cooling device 22 and the like is raised to an appropriate temperature by the heater 4 and the like, and the dehumidified air is dehumidified and the inside of the seat 1 ′ is changed. By sending the air, the humidity of the seat 1 'can be promptly reduced.

As described above, according to the present embodiment, the surface of the seat 1 'is kept dry even when the person is not sitting by minimizing the increase in humidity in the seat 1' due to sweating of the person. In this way, when the humidity of the surface of the seat 1 'exceeds 70%, when a new person sits on the seat, the person may feel wet or cold. Eliminates the inconvenience of feeling cold. In addition, the control about the humidity management in a seat mentioned above is:
Although it has been described that the operation is performed immediately after the person leaves the seat, the humidity of the seat 1 '(or the seat 1) is kept low even when the person is not seated, for example, immediately before the person sits down, What is necessary is just to prevent a person from feeling discomfort due to the humidity of the seat portion when seated.

Next, another embodiment of the present invention will be described.

That is, in the hot air unit 10 as one component of the air conditioner shown in the above embodiment, if the surface (not shown) of the heater 4 further supports platinum and palladium as noble metal catalysts. It can deodorize by decomposing hydrogen sulfide, mercaptan, ammonia, etc., which are regarded as unpleasant odors in the air. The deodorizing catalyst removes unpleasant odors in the seat 1 and the interior of the vehicle 24 inside the warm air unit 10 and sends deodorized air, so that the interior 24 can be kept comfortable. When a deodorizing catalyst is used, it is necessary to heat the deodorizing catalyst.

Next, still another embodiment of the present invention will be described.

That is, FIG. 4 is a schematic diagram showing a ventilation path in the seat 1 in this embodiment. That is, seat 1
The inside air supply path includes an adsorbent-containing tube 11 for adsorbing an unpleasant odor such as in the vehicle 24, a heater 4 for heating the air to be blown, and a blowout for blowing air provided on the surface of the seat 1. Blower 5 for sending out wind from hole 2
And an air passage 3 connecting them. Arrows in FIG. 4 indicate the flow of wind. That is, by the operation of the blower 5, the air that has passed through the adsorbent-containing tube 11 packed with activated carbon or the like absorbs the odor component contained therein, passes through the heater 4 and the blower 5, and blows out. 2, a part of which passes through the adsorbent-containing tube 11 again and is discharged into the vehicle interior 24. By doing so, the inside of the seat 1 and the inside of the car 2
The unpleasant odor of No. 4 is removed inside the adsorbent-containing tube 11 by operating the blower 5 and deodorized air is blown, so that the interior 24 of the vehicle is maintained in a comfortable environment.

It should be noted that both the method of decomposing odor components using a catalyst described in the above embodiment and the method of adsorbing odor components using an adsorbent shown in this embodiment may be used. .

Instead of the adsorbent-containing tube 11, as shown in FIG. 5, a scent-containing tube 12 in which a scent component is packed in a tube may be used. That is, it is well known that the scent generally stabilizes the mind. In particular, fragrances such as hinoki and basil that enhance attention, sleepiness like lemon, eucalyptus and peppermint, lavender and nutmeg that relieve stress, etc. preferable. Therefore, when the scent component is packed in the tube as described above, the interior of the car 24 is scented when the blower 5 is operated, and a comfortable environment can be provided. Also,
The fragrance stabilizes the mental state and masks unpleasant odors such as body odor and tobacco odor. The same effect can be obtained by attaching a dried herb to a part of the air duct as a scent component.

Next, still another embodiment of the present invention will be described.

In the above-described embodiment, the hot air unit 10 including the blower 5 and the air passage 3 are built in the seat 1. However, such installation is difficult in terms of installation space and driving power supply equipment. Is also conceivable. Therefore, in the seat 1 (or the seat 1 ′), the temperature sensor 7
And a humidity sensor 8 (the side portion 1c of the seat 1).
For example, the temperature sensor 7 may be provided also on a portion where no person sits), the control circuit 9 is provided, and the control circuit 9 and the air conditioner conventionally provided in the vehicle interior 24 are provided. Are electrically connected and controlled.

That is, in such a configuration, the seat 1
The temperature of the occupant and the state of perspiration are detected by the temperature sensor 7 and the humidity sensor 8, and the detection data from these sensors and the comfort physiological information stored in the storage element 13 in advance, regarding the state in which a person feels comfortable, Are compared, and the air conditioner is controlled so that they match. For example, when the detection data of the humidity sensor 8 becomes 65% RH or more, the cooling device 22 and the blower device 34 of the air conditioner or only the blower device 34 is operated to reduce sweat. In this case, if the body is cooled rapidly, the body cools down. Therefore, if the room temperature is lowered by 1 ° C., the room temperature is maintained for about 10 minutes, and then the humidity sensor 8 is used to monitor the occupant's sweating state and adjust the temperature to be gentle on the body. Air conditioning control becomes possible. The comfortable temperature range of the surface of the seat 1 is 33 ° C
It is known that the temperature is ~ 34 ° C.
If the temperature is not enough to reach the comfortable temperature range even after 10 minutes after the occupant is seated after the seat 4 is cold, the discomfort of the cold can be promptly eliminated by driving the heating device 34 or the like.

Next, another embodiment of the present invention will be described.

That is, in the above embodiment, both the temperature sensor 7 and the humidity sensor 8 are provided in the seat portion. However, although the control accuracy is slightly lowered, only one of the sensors is provided. Yes, of course.

That is, even when only the temperature sensor 7 is provided, the temperature can be appropriately controlled within the temperature range of 33 ° C. to 34 ° C. as described above.

When only the humidity sensor 8 is provided,
After a sensor (not shown) that is provided in advance separately from the humidity sensor 8 and that can detect a person's sitting or sitting position detects the person's sitting or sitting position, the detection data of the humidity sensor 8 is 65% RT. Then, the blower 5 is operated according to a command from the control circuit 9. Also, as mentioned above,
If the humidity sensor 8 detects 70% RT or more after the sensor capable of detecting the seating or the seating position of the person has been detected by the sensor capable of detecting the seating or the seating position of the person, the blower 5 may be operated to perform the humidity management in the seat. . At this time, it is more preferable that the cooling device 22 and the heater 4 are also operated.

In the above embodiment, the temperature sensor 7
And the humidity sensor 8 are independent of each other with respect to the operation of detecting the physiological state of the person, and the resulting control method has been described as being independent of each other. Of course, various air conditioners such as the blower 5 may be more effectively controlled by comprehensively utilizing data on the physiological condition.

Further, the sensor of the present invention, in the above embodiment,
Although it is a temperature sensor or a humidity sensor, any sensor that can detect a human physiological state, such as a radiation sensor using radiant heat, may be used.

In the above embodiment, the air conditioner of the present invention includes the cooling device 22, the heating device 23, the blowing device 25, the heater 4, the blower 5 and the like. It only needs to be able to adjust environmental conditions.

In the above embodiment, the comfortable physiological information of the present invention was experimentally determined based on temperature or humidity data. In short, however, it is possible to obtain a good correlation with a state in which a person feels comfortable. do it.

In the above-described embodiment, the sensor is mounted at the seat 1a of the seat 1 at the center, but it is possible to detect the physiological condition of a person, for example, at the center of the backrest 1b. All you have to do is place.

Further, the air conditioning control system for a seat of the present invention is used for a car in the above embodiment, but is not limited to this, and is applicable to fields using other seats such as trains, theaters, movie theaters and the like. It is possible.

In the above embodiment, the fact that the temperature detected by the temperature sensor 7 provided on the seat 1 where the person is not seated and the temperature of the wind have a correlation is utilized. Paying attention to the fact that there is a correlation between the temperature of the warm wind and the body temperature that rises due to the blowing of the wind, and the temperature detected by the temperature sensor 7 disposed on the seat 1 in the portion where the person is seated is In short, any method may be used as long as it is a means capable of detecting the temperature of the wind, such as utilizing the fact that the temperature of the wind has a correlation.

In the above embodiment, the means for controlling the rear and front seats 1, 1 'is used as a means for adjusting the environmental conditions in the vehicle so as to match the state in which the occupant feels comfortable. Although the description has been given, the on-off valves (not shown) are individually provided in the blowout holes 2 of the seat 1 (or the seat 1 '), and the opening and closing valves (not shown) can be individually controlled so that the same seat 1 (1') The environmental conditions can also be adjusted individually for one or more occupants in.

[0054]

As is apparent from the above description,
The present invention is such that environmental conditions that a person feels comfortable change in an individual depending on an activity state at that time,
Also, in consideration of the fact that a plurality of persons change depending on the characteristics of each person, the presence or absence of a person in the seat portion is determined based on comfort physiological information on a state in which the person feels comfortable.
In addition to the above, there is an advantage that the environmental conditions in the seat portion and the vicinity thereof can be adjusted so as to match the state in which a person feels comfortable.
