To prevent.

Further, in the second conventional example, an air-conditioning seat device as disclosed in Japanese Patent Application Laid-Open No. 11-123959 is disclosed as one using a hygroscopic material. That is, in FIG.
As shown in FIGS. 18 and 19, the backrest portion 9 has an air passage 10 therein, and the backrest portion 9 and the air passage 10 are provided.
A moisture permeable layer 11 having both air permeability and moisture permeability according to the gradient of the water vapor partial pressure is arranged between them, and the moisture vapor permeable from the backrest 9 flows into the air passage 10. Then, by passing the dried air through the air drying device 12 provided with the hygroscopic material to the air passage 10, the moisture permeable layer 11 allows the water vapor on the outer side of the backrest to permeate, and the water vapor is evaporated in the dry air. .

However, in the first conventional example, since dehumidification is performed by the cooling dehumidifier 4 in dehumidification, a drainage pipe for flowing dew condensation water is required, and therefore a special vehicle body is required. It requires some processing and is not easy to use as a mobile office chair.

In the second conventional example, the sweat generated in the human body is not absorbed except where it comes into contact with the chair, and since the moisture is absorbed through the clothes and the moisture permeable layer, the amount of absorbed sweat is small.
Further, since the temperature of the air discharged from the air dryer is high due to the heat of adsorption, there is a problem that a cool feeling cannot be obtained even if the air is blown out from the backrest as it is.

In addition, since the clothes are supplied through the clothes, a relatively high jet flow velocity is applied, so that the ventilation resistance such as reducing the outlet area is not increased. Therefore, the blower can be downsized and the noise can be reduced. Further, since the jet port is provided at the boundary portion, the structure of the ventilation passage can be simplified.

According to the eighth aspect of the present invention, there is provided an ejection port configured to eject air from the boundary toward the human body when seated.

Since a jet outlet is provided to jet air toward the human body when seated, a sufficient cooling sensation can be obtained even with a small supply flow rate and jet speed, so that a dehumidifying means or a cooling means for cooling is provided. Can be downsized.

According to a ninth aspect of the present invention, there is provided a jet port configured to supply air along the surface of the seat body.

Since the air is supplied along the surface of the seat body, the air is supplied from the ejection port at the boundary to a distance through the passage formed by the surface of the seat body and the hollows of the spine and the buttocks of the human body. You can

According to a tenth aspect of the present invention, a blower, a dehumidifying means for dehumidifying the air blown by the blower or a cooling means for cooling, are provided at the center of the back portion and the seat portion of the seat body, and when seated. It is provided with a jet port configured to open a jet port of a portion corresponding to a human body, and an air passage leading from the dehumidifying means or the cooling means to the jet port.

Since the jet port of the portion corresponding to the human body is opened when seated, dry air or cooling air is supplied from the jet port of only the portion corresponding to the human body. Therefore, since the air is not spouted wastefully from the other jet ports, a cool feeling can be obtained with less air.

The invention according to claim 11 is provided with a structure in which the opening area of the ejection port changes in accordance with the pressure of the human body when seated.

Further, since the opening area of the ejection port changes according to the pressure of the human body, more air can be supplied to the portion in contact with the human body, and effective air distribution can be performed.

According to a twelfth aspect of the present invention, a blower, a dehumidifying means for dehumidifying the air blown by the blower or a cooling means for cooling, a jet outlet for ejecting air, and the dehumidifying means or cooling means An air passage leading to an ejection port, and at least two types of ejection ports selected from a peripheral portion, a central portion, and a boundary portion of a back portion or a seat portion of a seat body are provided.

Since there are two or more kinds of jet ports, air can be supplied to a wider area of the human body, and the cooling feeling can be further enhanced.

Further, since the air is sequentially supplied from the two or more kinds of jets at a predetermined time interval, even if the air supply capacity is reduced, the air is sequentially supplied to a wide range of the human body so that a sufficient cooling feeling can be given. You can

According to a fourteenth aspect of the present invention, a blower such as a sirocco fan driven by a DC motor, a dehumidifying means such as an adsorbent for dehumidifying the air blown by the blower, and a temperature rise due to the heat of adsorption of the adsorbent. A heat exchanger for cooling the air, a skin of the seat body, or a jet port for jetting air provided in the peripheral portion of the seat body, a ventilation path leading from the dehumidifying means or the cooling means to the jet port, and the blower The control means for controlling the operation of the blower is configured to intermittently operate or continuously change the rotation speed of the blower. With the above structure, the air (3
5 ° C, 55% RH) is sent to the dehumidifying means and heat exchanger,
Water vapor is adsorbed by the adsorbent, the humidity is lowered, and heat is generated by the heat of adsorption (65 ° C., 3% RH) to become air. The high-temperature and low-humidity air is guided to the heat exchanger and cooled by the passenger compartment air (3
It becomes low-humidity air (7 ° C, 20%), is guided to the ventilation passage, blows out from the ejection port of the epidermis, and flows on the back side of the human body. At that time, by evaporating sweat on the body surface, the heat of vaporization is used to cool the human body and prevent stuffiness. At this time, the control means operates the blowing means for 3 seconds to blow air at 0.4 m ³ / min, and when the blowing is stopped for 9 seconds, the cold spots on the skin are intermittently stimulated and the air quantity is 0 on average. .1 m ³

An exhaust air duct switching means 40 for opening and closing an exhaust port 39 provided downstream of the heat exchanger 32;
It comprises a blower 27 and a control means 41 capable of varying the amount of air blown by the cooling fan 33.

In the above configuration, in the dehumidifying mode for dehumidifying the air inside the vehicle compartment, as shown in FIG. 2, the exhaust air duct switching means 40 is set to the position where the exhaust port 39 is closed and the blower 27 is driven. The air in the passenger compartment (35 ° C., 5 ° C.) sent to the dehumidifying means 29 by the blower 27 at a flow rate of 0.2 m ³ / min.

RH). The high-temperature and low-humidity air is guided to the heat exchanger 32, and the lower part of the heat exchanger 32 is cooled by the passenger compartment air to become low-temperature low-humidity air (37 ° C, 20%), which is guided to the ventilation passage 37 and the skin 35. It blows out from the spout 36 and flows on the back side of the human body. At that time, by evaporating the sweat on the human body surface, the heat of vaporization is used to give a cool feeling to the human body and prevent stuffiness. In addition, in FIG. 4, the sensory test results of the jetting temperature and the cooling sensation of the back when a dry air having a temperature of 0.2 m ³ / min and a humidity of 20% at room temperature or higher is jetted in a room at room temperature 35 ° C. and humidity 55% RH. Indicates. As shown in FIG. 4, if the temperature is 39 ° C. or lower, a cooling sensation can be obtained by the heat of vaporization of sweat. In addition,
When air with a temperature of 0.2 m ³ / min and a temperature of 31 ° C. and a humidity of 75% was ejected, the cool feeling was the same as that of the dry air of 38 ° C. and 20%.

In the present invention, the heat exchanger 32 of aluminum extruded material provided with fins 31 on both sides is used. The same structure can be obtained by bonding with a conductive material. The material of the heat exchanger is
It goes without saying that heat exchange performance can be improved by selecting materials with high thermal conductivity such as copper and silver in addition to aluminum.

In the present invention, the cooling fan 33 forcibly blows the air in the vehicle interior to the lower portion of the heat exchanger 32 to cool it, but it is possible to increase the size of the heat exchanger 32 in the storage space. It goes without saying that the heat exchanger 32 is heat-exchanged and cooled by natural convection only if possible. Further, if the heat exchanger 32 is configured to be blown with air from an air conditioner such as an air conditioner, the heat exchanger can be effectively cooled without adding a component such as the cooling fan 33. Needless to say.

When the vehicle is driven immediately after parking in the summer, the atmosphere in the interior of the vehicle becomes hotter near the ceiling. Therefore, the suction port of the cooling fan 33 for cooling the heat exchanger 32 is installed. The heat exchange performance of the heat exchanger 32 is improved as the place is provided at a place where the ambient temperature is as low as possible, such as near the floor in the vehicle.

Further, in the regeneration mode for recovering the dehumidifying performance of the dehumidifying means 29, as shown in FIG. 3, the blower is stopped, the exhaust air passage switching means 40 is set to the position where the exhaust port 39 is opened, and the heating means 38 is turned on. In the case of silica gel, electricity is supplied to heat the adsorbent up to 130 ° C. to release water vapor from the adsorbent 28 and release it as high-humidity air from the exhaust port 39 into the passenger compartment. Since the exhaust port 39 is located above the adsorbing means 28, the generated steam becomes an updraft, and the air in the vehicle interior is adsorbed by the adsorbent 2
Since the flow that flows into 8 is generated, the adsorbent 28 is regenerated in a short time. In addition, since the dehumidifying means 29 and the heat exchanger 32 are thermally cut off by the exhaust air passage switching means 40, the heat generated by the heating means 38 is not taken away by the heat exchanger 32 and is efficiently transferred to the dehumidifying means 29. Since it is transmitted, the regeneration of the adsorbent 28 of the dehumidifying means 29 is quick.

In the configuration in which the motor of the blower 27 is a DC motor and the control means 41 for controlling the number of revolutions is provided, the blower 41 blows a flow rate of 0.
02m ³ / min Control to make a weak wind. Heating means 38
When the power is turned on, the temperature of the air becomes 120 ° C. to 140 ° C. and is sent to the adsorbent 28 of the dehumidifying means 29 to heat the adsorbent 28 and blow off the water vapor desorbed from the adsorbent 28 to remove the dehumidifying means 29. The adsorbent 28 can be regenerated in a short time.

Although the seat device mounted on the vehicle has been described, it goes without saying that it can be applied to a seat device for home or office.

(Embodiment 2) FIG. 5 is a perspective view of an air conditioning seat apparatus according to Embodiment 2 of the present invention. The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The second embodiment is different from the first embodiment in that the ejection port 36 is provided only in the peripheral portion 42 which does not come into contact with the human body when the seat portion 25 and the back portion 26 are seated as shown in FIG. The ejection port 36 is configured by using the orientation of the ejection port or a fluid element so that air is ejected from the peripheral portion 42 of the seat body 24 toward the human body when seated.

The operation and action will be described below. Since the peripheral portion 42 has the ejection port 39 at the time of sitting, the human body does not block the ejection port 39 and the peripheral portion 42 of the back portion 26 or the seat portion 25 is prevented.
The dry air can be reliably supplied from the seat body 2
It is possible to maintain a comfortable air conditioning environment in the vicinity of four. Further, since the dry air can be directly jetted and supplied to the human body, a comfortable feeling can be obtained in a short time.

In this embodiment, the one having the dehumidifying means 29 has been described, but a cooling means for producing cooling air in a refrigeration cycle using a Peltier element or a compressor may be used,
A cooling sensation can be provided as in the case of supplying dry air. Although the seat device mounted on the vehicle has been described, it goes without saying that it can be applied to a seat device for home or office.

The third embodiment differs from the first embodiment in that the headrest 43 is provided with an ejection port 36 for ejecting air toward a part of the human body not covered with clothes, as shown in FIG. Then, from the dehumidifying means 29 to the upper air passage 44
Is provided in the headrest 43, and the dry air is supplied to the pressure equalizing chamber 45 communicating with the ejection port 36.

Next, the operation and action will be described. The dehumidifying means 2
The dehumidified air guided from 9 through the upper air passage 44 to the pressure equalizing chamber 45 is jetted and supplied from the jet outlet to the occipital region, the neck muscles, the shoulder portion, and the like, which are sensitive to the cool feeling.

Since the dry air can be directly jetted and supplied to the skin of the human body such as the back of the head and neck, the amount of supplied air is small and a comfortable feeling can be obtained, and the dehumidifying means 29 can be downsized accordingly. In addition, since the distance between the headrest 43 and the human body becomes short, dry air penetrates the clothes and permeates in a region near the spout 36 such as the shoulder, and even if spouting a small amount, it spreads over a wide range and the spouting speed decreases. Since it can be supplied in a state where it is not supplied, the blower 27 can be downsized, and the rotation speed can be reduced to achieve low noise.

In this embodiment, the one having the dehumidifying means 29 has been described, but a cooling means for producing cooling air in a refrigerating cycle using a Peltier element or a compressor may be used, and a cooling feeling similar to the case of supplying dry air can be obtained.

As shown in FIG. 9A, the ejection port 36 communicating with the ejection chamber 47 has a slit-type nozzle configuration, a fluid element utilizing the Coanda effect, or the like that can control the ejection direction. Then, when seated, dry air is ejected from the boundary portion 46 toward the human body.

Next, the operation and action will be described. At the boundary portion 46 between the back portion 26 and the seat portion 25, there is usually a space portion where the human body does not come into contact, and since the jet port 36 is provided there, dry air is directly applied to the human body. Since it can be supplied, the jet outlet 36 is not blocked by the human body. Further, since the dry air is supplied through the clothes, a relatively high jet flow velocity is provided, so that the ventilation resistance such as narrowing the outlet area is not increased. Therefore, the blower 27 can be downsized and noise can be reduced. Further, since the jet port 36 is provided at the boundary portion 46, the structure of the ventilation passage 37 can be simplified.

Since the ejection port 36 is provided so as to eject air toward the human body when seated, a sufficient cooling sensation can be obtained even with a small supply flow rate and ejection speed, so that the dehumidifying means 29 is made compact. You can

Further, as shown in FIG. 9B, since a jet nozzle 36 configured to supply air along the surface of the seat body 24 by using a slit nozzle, a fluid element or the like is provided, the seat body 24 Air can be supplied from the ejection port 36 of the boundary portion 46 to a distant place through a passage formed by the surface of the body and the hollow of the spine or the buttocks of the human body.

The opening / closing means 50 is provided so that the opening area of the ejection port 36 changes according to the pressure of the human body when seated.

Next, the operation and action will be described. Since the ejection port 36 of the portion corresponding to the human body is opened when seated, dry air is supplied from the ejection port 36 of only the portion corresponding to the human body. Therefore, the air is not ejected from the other ejection ports 36 unnecessarily, and a cool feeling can be obtained with a small amount of air. Further, as shown in FIG. 11, since the opening / closing means 50 changes the opening area of the ejection port according to the pressure of the human body, more air is supplied to the portion in contact with the human body,

The sixth embodiment is different from the first embodiment as shown in FIGS. 12 to 14, in which the peripheral portion 42 and the central portion 49 are shown in FIG. 12, the boundary portion 46 and the central portion 49 are shown in FIG. 13, and the peripheral portion is shown in FIG. The point is that the ejection port 36 is provided in the portion 42 and the boundary portion 46. Then, as shown in FIG. 15 (A), the control means 41 and the discharge air passage switching means 40 serve to change the air blowing means to three.
The exhaust airflow path switching means 40 is opened so that the airflow is 0.4 m ³ / minute per second, and the exhaust airflow path switching means 40 is closed so that the air flow is stopped for 9 seconds. The cold spot of the skin is intermittently stimulated by the above operation, and the feeling of cooling is greater than that of blowing air at an average air volume of 0.1 m ³ / min. Therefore, it is possible to reduce the average blown air amount to obtain the same cooling feeling, and it is possible to reduce the size of the adsorbent and the heat exchanger. Moreover, as shown in FIG.
5m ³ / min to 0.4m ³ / continuously trying to change in minutes,
The same effect can be obtained by adjusting the opening degree of the exhaust air duct switching means 40. Further, the same effect can be obtained by controlling the rotation speed of the blower 27 by the control means 41 instead of adjusting the air volume by the discharge air passage switching means 40. Even when a cooling means is used instead of the adsorbent and the heat exchanger, the cooling effect is increased and the same effect can be obtained by changing the air flow rate.

Further, air is sequentially supplied from two or more kinds of jet ports 36 at predetermined time intervals to reduce the amount of air blown at each location, and to change as shown in FIGS. 15 (A) and 15 (B). Then, by sequentially supplying to a wide range of the human body, it is possible to give a sufficient cooling feeling without increasing the total air flow rate.
