The plurality of jet nozzles 34 communicated with each other. A heater 35 is provided between the pad portion 32 on the back side of the skin 31.
A footrest 40 is provided in front of the seat 11. The structure of the footrest 40 is essentially the same as the seat 11. That is, it has the ventilation path 45 connected to the ventilation path 18 inside the footrest 40. The air passage 45 communicates with a plurality of ventilation passages 43 that penetrate the pad portion 42 and extend to the skin 41, and the ventilation passage 43 communicates with a plurality of jet ports 44 formed in the skin 41. On the surface of the footrest 40, a deodorizing device 47 for deodorizing air blown to the footrest 40 is provided. As the deodorizing device 47, an odor absorber such as activated carbon or an ozone generator is used. A heater 46 is provided between the pad 41 on the back side of the skin 41.

Next, the operation will be described.
During the air conditioning operation, the damper 17 is operated to close the exhaust air passage 20 and open the air blowing passages 18 and 19. The air blown from the blower 12 is dehumidified by the dehumidifying unit 16, and the dehumidified air is supplied to the blower passage 18 and the blower passage 19. The dehumidified air that has passed through the air blowing path 18 is branched into each of the plurality of ventilation paths 23 of the seat sheet 11, and is ejected from the plurality of ejection openings 24 formed in the skin 21 to the surface of the seat sheet 11. The dehumidified air jetted from the jet outlet 24 of the seat 11 is jetted from the buttocks of the occupant sitting on the seat 11 to the back of the thigh. When the skin 21 of the seat 11 is hot, such as in summer, the skin 21 of the seat 11 is cooled by the injected dehumidified air and the temperature is lowered. When the occupant is sweating, the sweat is vaporized and dried by the dehumidified air, and the occupant can feel a cool feeling by the heat of vaporization.

It spouts onto the surface of the footrest 40. The dehumidified air ejected from the spout 44 of the footrest 40 is jetted to the feet of the passenger sitting on the seat 11. Therefore, when the skin 41 of the footrest 40 is at a high temperature, the skin 41 of the footrest 40 is cooled by the injected dehumidified air, and the temperature is lowered. When the occupant's feet are sweating, the sweat is vaporized and dried by the dehumidified air, and the occupant can feel a cool feeling by the heat of vaporization. Furthermore, since the airflow blows from below on the foot placed on the footrest 40, it has an acupressure effect on the foot.

By the way, when a foot is wearing shoes, a strong odor often occurs due to stuffiness. In such a case, when the foot is placed on the footrest 40 of this embodiment, the dehumidified air flows around the foot, thereby eliminating foot stuffiness. The odor is deodorized and deodorized by the deodorizing device 47.

Released into the room. When this operation is performed for a predetermined time, the moisture adsorbent 14 is regenerated by releasing water vapor and drying. The dry state of the moisture adsorbent 14 can be determined by detecting the temperature of the moisture adsorbent 14 with the temperature detector 49. When the regeneration operation is completed, the heating of the heater 15 is stopped, the damper 17 is operated to close the exhaust air passage 20, and the air passages 18 and 19 are opened to prepare for the air conditioning operation.

The dehumidifying part 16 supports the moisture adsorbent 14 such as zeolite or silica gel on the wire mesh heater 15 and arranges the moisture adsorbent 14 and the heater 15 in close proximity, thereby making the dehumidifying part 16 small and It is possible to improve the reproduction efficiency. As an integrated configuration of the moisture adsorbent 14 and the heater 15, a configuration in which the moisture adsorbent 14 is supported on the wire mesh heater 15 is simple. However, as shown in FIG. It is composed of a resistance heating element, and an undercoat layer is formed by sintering aluminum hydroxide, cerium nitrate or the like on the surface, and a moisture adsorbing body 14 is supported thereon, thereby further improving the regeneration efficiency. be able to. That is, since the undercoat layer is chemically bonded to the moisture adsorbing body 14, the adhesion is improved, and the heat of the heater 15 is directly transmitted to the moisture adsorbing body 14, so that the temperature rising rate of the moisture adsorbing body 14 is high. Therefore, the regeneration operation can be performed in a short time of about several tens of seconds, and the regeneration efficiency is improved.

Generally, the air dehumidified by the dehumidifying unit 16 has a temperature of 40 ° C. or higher due to heat of adsorption during dehumidification. This temperature of the air is too high to be ejected from the seat 11, the seat back 30, and the footrest 40 in the summer. Therefore, heat is exchanged by the heat exchanger 80 and cooled to, for example, 37 ° C. or lower and supplied to the air passages 18 and 19. If the temperature of the air blown is 37 ° C. or less, the occupant can feel cooling even in summer and can eliminate sweat and stuffiness.
In winter, the dehumidified air may be heated by the heat exchanger 80 to provide a heating effect.
The heat exchanger 80 can also be applied to the embodiment in which the seat seat 11, the seat back 30, and the footrest 40 described with reference to FIGS. 4, 5, and 7 are separated. In this case, what is necessary is just to provide in the ventilation path from each air blower 51, 52, 53 independently to each of the seat seat 11, the seat back 30, and the footrest 40.

  In the fifth embodiment, the heat exchanger 80 is provided in the air passage 13, but in this embodiment, a negative ion generator is provided instead of the heat exchanger 80. Negative ions are known to make people feel calm and relaxed. Therefore, in this embodiment, negative ions are added to the air ejected from the seat 11, the seat back 30, and the footrest 40 by the negative ion generator. As a result, the occupant can drive the car in a good physical state.

  The air-conditioning seat device according to the present invention is useful as an air-conditioning seat device for chairs used in automobiles, offices, theaters, homes, etc., chairs for outdoor activities, and the like. Usually, in a car seat device, the interior of the vehicle and the seat seat become hot during parking in the summer, so that the passenger feels a strong discomfort when sitting on the seat, but according to the air-conditioning seat device according to the present invention, Since the discomfort in the case can be eliminated in a short time, it is extremely useful as an air-conditioning seat device for automobiles.
