[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air-conditioning seat device that can provide a comfortable seating feeling even when the environmental temperature is high or the user sits for a long time, such as an automobile or an office chair.
[0002]
[Prior art]
As a conventional air-conditioning seat device of this type, as shown in FIG. 18, an air bag 3 that forcibly sucks outside air through a skin cloth 2 at a portion where the back of the human body of the seat body 1 abuts is incorporated in the seat body 1. In addition, a dehumidifying and drying device 6 comprising a cooling dehumidifier 4 and a heating dryer 5 for dehumidifying and drying the outside air taken in by the air bag 3 and exhausting it to the back of the human body through the air bag 3 is incorporated in the headrest 1a and further dehumidified and dried. The apparatus 6 and the air bladder 3 are configured to communicate with each other through an intake air passage 7 and an exhaust air passage 8. In the figure, arrows indicate the flow of air.
[0003]
In the above configuration, outside air having a temperature of 32 ° C. and a humidity of 80% on the back of the human body is sucked into the air bag 3 through the skin cloth 2, enters the cooling dehumidifier 4 through the intake air passage 7, and is cooled and dehumidified (condensed) to a temperature of 15 ° C. The air becomes 100% humidity. Then, this air is sent to the heat dryer 5 and dried by heating to become air at a temperature of 30 ° C. and a humidity of 50%, enters the air bag 3 through the exhaust ventilation path 8, and blows out from the skin cloth 2 toward the back of the human body. , Preventing the occurrence of stuffiness while preventing the body temperature from being taken away by cooling air. (For example, refer to Patent Document 1).
[0004]
Moreover, as an air-conditioning seat apparatus using a hygroscopic material, as shown in FIGS. 19, 20, and 21, the backrest portion 9 has an air passage 10 therein, and the space between the backrest portion 9 and the air passage 10 is Is provided with a moisture permeable layer 11 having both air permeability and moisture permeability according to the gradient of the water vapor partial pressure, and water vapor permeable from the backrest portion 9 flows into the air passage 10. The moisture permeable layer 11 allows water vapor on the outside of the backrest portion 9 to permeate by flowing the air dried through the air drying device 12 having a hygroscopic material into the air passage 10 as indicated by an arrow. Evaporates in dry air.
[0005]
The air drying device 12 is as shown in FIG. That is, 15 and 16 are reaction vessels filled with a moisture-absorbing material such as zeolite or silica gel having air inlets 17 and 18, respectively, and have electric heaters 21 and 22 integrated, respectively, and electrically driven air flaps. 14, the flow path is switched to an air outlet 20 connected to the inlet of the air passage 10 and an air outlet 19 opened in the passenger compartment. In the figure, reference numeral 13 denotes a power source, and arrows indicate the flow of air.
[0006]
In the above configuration, in order to continuously operate the air drying device 12, the two reaction vessels 15 and 16 are alternately switched between a moisture absorption process and a regeneration process. When one reaction vessel 15 is regenerated by the electric heater 21 (regeneration process), the other reaction vessel 16 dries the air flowing through the inside by the moisture absorption action of the adsorbent material, and heats the temperature of the air with the heat of adsorption. Yes (moisture absorption process).
[0007]
When the adsorbent is saturated in the reaction vessel 16, the air flap 14 is switched as indicated by a broken line to energize the electric heater 22 to regenerate the reaction vessel 16, and the reaction vessel 15 causes the air flowing through the inside to be absorbed by the adsorbing material. dry. Further, as shown in FIG. 21, a convection fan 23 for forcibly guiding air may be disposed in the vicinity of the air outlet 19 (see, for example, Patent Document 2).
[0008]
However, in the former prior art, since the dehumidification is performed by the cooling dehumidifier 4, a drain pipe for flowing condensed water is required. Therefore, a special processing is required for the seat including the automobile as a seat for the automobile. In addition, there is a problem that it cannot be easily used as a movable office chair.
[0009]
In the latter of the above prior art, sweat generated in the human body is not absorbed except where it touches the chair, and moisture is absorbed through the clothing and the moisture permeable layer 11, so that the amount of sweat absorbed is small. Moreover, since the temperature of the air that has exited the air drying device 12 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 from the backrest 9 as it is.

DETAILED DESCRIPTION OF THE INVENTION
Since the object of the present invention described above can be achieved by using the configuration described in each claim as an embodiment, the effects of the configuration will be described together with the configuration of each claim. The specific terms that require explanation in the configuration will be described in detail in the embodiment of the present invention by adding a detailed explanation.
[0017]
The invention according to claim 1 is a seat body having a seat portion and a back portion. An air-conditioning seat device that provides a cool feeling to a person seated in a seat by providing a duct inside, blowing out air blown by a blower from the seat body through the duct, In the dehumidifying mode, a first blower that sucks and blows air in an environment where the seat body is located, a dehumidifying means that adsorbs moisture of the air blown by the first blower, and a dehumidifying means provided in the seat body and dehumidified by the dehumidifying means A dehumidified air jet port for jetting the generated air toward the human body seated on the seat body; The first blower, the dehumidifying means, and the dehumidified air outlet are communicated by a dehumidified air duct, and the dehumidified air is ejected from the dehumidified air outlet. , on the other hand, A second air blower that sucks and blows air in an environment with the seat body; an air outlet that is provided in the seat body and blows air from the second blower toward a human body seated on the seat body; An air duct that communicates between the second blower and the air outlet, the air is ejected from the air outlet, and the path includes the first blower, the dehumidifying means, the dehumidified air duct, and the dehumidified air outlet. The second air blower, the air duct, and the air jet outlet are provided as different paths that are not common. A dehumidifying air-conditioning unit having a heating means for heating the dehumidifying means in a regeneration mode for restoring the dehumidifying performance of the dehumidifying means, and a control means for controlling the operation of the dehumidifying air-conditioning unit, the control means comprising at least the heating An air-conditioning seat device that performs control to operate the second blower while the means is operating.
[0018]
According to the case of the air-conditioning seat in which the above-described embodiment is mounted on a car seat, in the dehumidifying mode, after the operation is started, the first air blower is driven to perform the dehumidifying operation for dehumidifying the air in the passenger compartment. 2m ^Three The air at 35 ° C. and 55% RH sent to the dehumidifying means at a flow rate of / min is adsorbed with water vapor by the dehumidifying means to reduce the humidity and generate heat by the heat of adsorption to become 65 ° C. and 3% RH air.
[0019]
This high-temperature and low-humidity air is naturally heat-exchanged from the structure while being guided to the dehumidifying air outlet of the seat body, or the interior of the passenger compartment is 35 ° C immediately after boarding by an in-vehicle air conditioner such as a car air conditioner. 55% RH air, but rapidly becomes low temperature and low humidity with the passage of time. When the air in the passenger compartment is sucked by the first blower, it becomes low humidity air of 37 ° C. and 20% RH, and the dehumidified air of the seat body It blows out from the spout, flows on the surface of the human body, vaporizes the sweat on the body surface and clothes, and cools the human body by latent heat.
[0020]
Further, the second blower for blowing the passenger compartment air is when the first blower stops or rotates at a low speed while the heating means is operating in the regeneration mode of the dehumidifying means by the control means, and the dehumidifying air is not blown out from the dehumidifying air jet outlet. But for example 0.2m ^Three The cabin air is blown out from the air outlet of the seat body at a flow rate of / min. Accordingly, air is always flowed to the back side of the human body, and the sweat on the surface of the body is vaporized, thereby removing the heat of vaporization and giving a cool feeling to the human body as well as preventing a feeling of stuffiness.
[0021]
Further, for example, the dehumidifying air conditioning unit alternately performs the dehumidifying mode and the regeneration mode by the control means, and the dehumidifying air and the mere air that has not been dehumidified are alternately blown out from the seat main body, so that the air continuously flows as a result. Therefore, the cool sensation that occurs when air is blown intermittently is not interrupted. Then, it flows directly on the back side of the human body, and at that time, the sweat on the body surface is vaporized, thereby removing the heat of vaporization and giving a cool feeling to the human body, and also preventing a feeling of stuffiness. In addition, by alternately repeating dehumidified air and simple air blowing, a fluctuation effect of the wind due to the air blown out can also produce a fluctuation effect, making it easier to feel cool feeling.
[0029]
Claim 2 In the invention according to the description, the control means performs an operation of alternately repeating the dehumidification mode and the regeneration mode for a certain time after the operation of the dehumidification air conditioning unit is started, and the heating means of the dehumidification air conditioning unit is not operated after the certain time has elapsed. The air-conditioning seat device performs a blowing mode operation for operating at least one of the first blower and the second blower.
[0030]
In general, when driving a parked car under hot weather in summer, the passenger compartment is very hot and a rapid cool feeling is desired immediately after sitting. In general, the vehicle interior is cooled by low-temperature dehumidified air of 25 ° C. and 20% RH blown from an air conditioner such as a car air conditioner, but a certain time of about 15 to 20 minutes is required until the room temperature decreases. The situation is not in time because it takes.
[0031]
According to the case of the air-conditioning seat in which the above embodiment is mounted on a car seat, the dehumidifying air-conditioning unit is operated repeatedly repeating the dehumidifying mode and the regeneration mode for a certain time after the start of operation of the dehumidifying air-conditioning unit. Air and air that is not simply dehumidified are ejected from the seat body, and by flowing through the back side of the seated human body, the sweat on the body surface is vaporized, thereby removing the heat of vaporization and immediately giving a cool feeling to the human body. Also prevent.
[0032]
And after a certain period of time after the start of operation of the dehumidifying air conditioning unit by the control means, for example, after the temperature and humidity in the passenger compartment are lowered by an air conditioner such as a car air conditioner, at least the first blower and the heating means are not operated. Since one side of the second blower is driven to perform the air blowing mode operation in which the air in the passenger compartment is sucked and blown out from the seat body, the air flows on the back side of the seated human body, giving a cool feeling, and feeling of stuffiness To prevent. In this case, since the regeneration mode operation is not performed, the heating means does not operate, so that power consumption is reduced.
[0033]
Claim 3 In the invention according to the description, the control means performs the operation of alternately repeating the dehumidification mode and the regeneration mode after the start of the operation of the dehumidification air conditioning unit, and dehumidifies based on at least one information of the temperature detection means and the humidity detection means. It is an air conditioning seat device that performs a blowing mode operation in which at least one of the first blower and the second blower is operated without operating the heating means of the air conditioning unit.
[0034]
According to the above embodiment, the dehumidifying air conditioning unit performs the operation of alternately repeating the dehumidifying mode and the regeneration mode after the operation is started by the control means, so that the dehumidified air and the air that has not been dehumidified are immediately ejected from the seat body alternately. By evaporating the sweat on the back side of the seated human body, it removes the heat of vaporization and immediately gives a cool feeling to the human body, and also prevents the feeling of stuffiness.
[0035]
In such a process, the control means performs at least one of the first blower and the second blower and performs only the blow mode operation based on at least one information of the temperature detection means and the humidity detection means. Therefore, for example, if the seat body is a passenger compartment, only air is blown on the basis of one or more information on the temperature and humidity of the air in the passenger compartment reduced by the car air conditioner, and the heat of vaporization of the human body seated more than necessary is taken away. Therefore, the feeling of comfort is improved and the power consumption of the dehumidifying air conditioning unit can be reduced.
[0039]
Claim 4 The invention according to the description is an air conditioning seat device in which the control means controls the air flow rate of the first blower to be increased when the temperature and humidity of the air in the environment where the seat body is located after the start of operation is higher than the set value. is there.
[0040]
According to the case of an air-conditioning seat in which this embodiment is mounted on a car seat, the room temperature rises to 35 ° C. or higher in a parked vehicle room under the hot weather in summer, and the skin of the seat body is about 60 ° C. To rise. In such an environment, the first blower for dehumidification by the control means blows out a large amount of dehumidified air from the dehumidified air outlet of the seat body, so that the human body seated on the seat body can quickly get a cool feeling. In addition, the capacity of the dehumidifying means can be reduced.
[0041]
In addition, when the air temperature in the passenger compartment is lowered by the car air conditioner and the seat temperature of the seat body is lowered, a cool feeling can be obtained even if the air flow rate of the first blower is lowered because the passenger compartment temperature is lowered. Therefore, comfort can be maintained and the power consumption of the air conditioning unit can be reduced without cooling the body more than necessary.
[0042]
Claim 5 The invention according to the description has a driver detection means, and the control means is a regeneration in which the dehumidification air conditioning unit recovers the dehumidification performance after the detection by the driver detection means and before the operation of the first blower or the second blower is started. This is an air-conditioning seat device that is controlled to perform mode operation.
[0043]
According to the above embodiment, when the driver detecting means detects that the driver approaches the vehicle, gets on the vehicle, or sits on the seat body, the heating means is energized to increase the temperature of the dehumidifying means and adsorb the water vapor. Desorb and release. Then, after that, the operation of the dehumidifying air conditioning unit is started, the first blower is operated, and a cool feeling is given by sending the dehumidified air from the dehumidified air outlet to the human body seated. Accordingly, since the dehumidifying air conditioning unit can always be operated with the capacity of the dehumidifying means being maximized, the dehumidifying capacity is large, a great cooling feeling can be obtained immediately after sitting, and it is extremely useful as an air conditioning seat device for automobiles.

In order to control the open / close switching operation of the exhaust air passage switching means 53 and the power consumption of the heating means 40, a program for executing the control sequence shown in FIG. 6 is stored.
[0053]
The operation and action of the above embodiment will be described as an air-conditioning seat mounted on a car seat. In general, under the hot weather in summer, the room temperature in a parked vehicle compartment rises to 35 ° C or higher, and the seat skin rises to about 60 ° C. Therefore, when the driver gets on and starts operating the air conditioning seat device by the control means 54, first, as shown in FIG. 6, the regeneration mode of the dehumidifying air conditioning unit 43 is controlled, and the exhaust air path switching means 53, the heating means 40, The second blower 39 is energized and the first blower 34 is stopped.
[0054]
In this regeneration mode, as shown in FIG. 3, the exhaust air passage switching means 53 is driven by the control means 54, the passage leading to the dehumidified air discharge port 38 of the unit case 44 is closed and the exhaust port 47 is opened, and further the first blower 34 is stopped, heated by the energized heating means 40, the adsorbent 35 of the dehumidifying means 36 rises in temperature and desorbs the adsorbed water vapor, and the water vapor is naturally released from the exhaust port 47 to the outside of the seat portion 32 by the convection action. Is done.
[0055]
In this regeneration mode, the first blower 34 uses a DC motor, and the amount of blown air is adjusted to 0.02 m by adjusting the rotational speed by the control means 54. ^Three By controlling so as to be a weak wind per minute, the heated heating means 40 is heated, and air having a temperature of 120 ° C. to 140 ° C. is sent to the adsorbent 35 of the dehumidifying means 36, and from the adsorbent 35 If the desorbed water vapor is forcibly discharged from the exhaust port 47, the adsorption capacity of the dehumidifying means 36 can be restored efficiently in a short time.
[0056]
In this way, in the regeneration mode shown in FIG. 6, the second blower 39 is rotated to 0.2 m. ^Three The air in the passenger compartment blown at a flow rate of / min is guided to the air duct 60 from the air discharge port 48 of the dehumidifying air conditioning unit 43 and led to the air distribution path 52 of the seat portion 32 and the back portion 33, and spreads. It ejects toward the human body seated from the plurality of air jets 50 in the seat portion 32 and the back portion 33 of the main body 31 to prevent a feeling of stuffiness due to sweat.
[0057]
Next, when the function of the dehumidifying means 36 is restored in the regeneration mode for a certain period of time, the dehumidifying air conditioning unit 43 is operated in the dehumidifying mode for a certain period of time by the control means 54 as shown in FIG. The first blower 34 is energized, the energization of the heating means 40 and the second blower 39 is stopped, the vehicle interior air is dehumidified, and the dry air is ejected from the dehumidified air outlet 49.
[0058]
That is, as shown in FIG. 4, the exhaust air passage switching means 53 is driven by the control means 54 so that the passage leading to the dehumidified air discharge port 38 of the unit case 44 is opened and the exhaust port 47 is closed. The air in the vehicle compartment sucked into the dehumidifying means 36 is blown by driving 34. And 0.2 m by the first blower 34 ^Three The 35 ° C. and 55% RH air in the passenger compartment sent to the dehumidifying means 36 at a flow rate per minute is adsorbed by the adsorbent 35 to reduce the humidity and generate heat by the adsorption heat, resulting in high-temperature and low-humidity air. The dehumidified air discharge port 38 of the dehumidifying air conditioning unit 43 is guided to the dehumidified air duct 59 and led to the dehumidified air distribution path 51 of the seat portion 32 and the back portion 33 respectively.
[0059]
Subsequently, the high-temperature and low-humidity air that has spread into the dehumidified air distribution path 51 is discharged from the dehumidified air outlet 49 of the seat body 31 until the skin 37, the cushion material 41, the seat housing 42, and the dehumidified air distribution. Heat is removed by the constituent members such as the passage 51 and heat exchange is performed, and the low-humidity air of 37 ° C. and 20% RH is obtained, and a plurality of dehumidified air outlets 49 in the seat portion 32 and the back portion 33 of the seat body 31 are obtained. It spouts out toward the human body seated from and flows through the thigh, waist, and back of the human body. At that time, by evaporating the sweat on the body surface, the latent heat of vaporization is taken away and a cool feeling is given to the human body, and a feeling of stuffiness is prevented.
[0060]
In such a regeneration mode and a dehumidifying mode, the dehumidifying air conditioning unit 43 performs an alternating operation repeatedly within a certain time T1 after the start of operation as shown in FIG. The air is blown, the clothes absorb moisture when the air is in the passenger compartment, and then, when dry air, the latent heat of vaporization is taken away, and a cooler feeling can be continuously obtained.
[0061]
On the other hand, since the car is equipped with a car air conditioner, the temperature and humidity of the air in the passenger compartment are lowered with the lapse of time by the car air conditioner that is operated simultaneously with the ride. Therefore, after the elapse of a certain time T1 in which the regeneration mode and the dehumidification mode are alternately operated, the control unit 54 switches to the operation in the air blowing mode.
[0062]
In the operation in the air blowing mode, the exhaust air passage switching means 53 is set to a position where the passage leading to the dehumidified air discharge port 38 of the unit case 44 is opened as shown in FIG. 4 and the exhaust port 47 is closed, as shown in FIG. The energization to the heating means 40 is stopped, and the first blower 34 and the second blower 39 are driven. Then, the air in the passenger compartment that has been sucked in by the first blower 34 is dehumidified by the dehumidifying means 36, led from the dehumidified air discharge port 38 to the dehumidified air distribution path 51 via the dehumidified air duct 59, and spread. The air in the passenger compartment, which has been taken in by the blower 39 and is air-conditioned by the car air conditioner, is led to the air distribution path 52 from the air discharge port 48 through the air duct 60 and spreads, and the seat 32 and the back 33 of the seat body 31 are spread. 0.2 m from each of the plurality of dehumidifying air outlets 49 and the plurality of air outlets 50 ^Three / M total 0.4m ^Three A blast volume per minute blows toward the sitting human body to prevent stuffiness due to sweat.
[0063]
Therefore, during operation in the air blowing mode after a certain period of time has elapsed since the start of operation, the air blown out from the plurality of dehumidifying air outlets 49 and the plurality of air outlets 50 is the air in the passenger compartment conditioned by the car air conditioner. Since it is used, it is possible to efficiently give a cool feeling to the seated human body. Moreover, since the heating means 40 is stopped, power consumption can be kept low.
[0064]
In general, in a car parked under a hot summer sun, the temperature of the seat surface is about 60 ° C., and the temperature of the air in the passenger compartment is also 35 ° C. and 55% RH. It is desirable to get a cool feeling immediately when riding in a car in a rough environment.
[0065]
Therefore, the control means 54 in the first embodiment may store a program for executing the control sequence shown in FIG. 7 instead of the control sequence shown in FIG. That is, as shown in FIG. 7, when the control unit 54 alternately repeats the regeneration mode and the dehumidification mode for a certain time T1 from the start of operation, the air flow rate of the first blower 34 and the second blower 39 is set to 0.4 m. ^Three In the air blowing mode after the elapse of a certain time T1, when the air conditioner is driven and the air in the vehicle interior is 25 ° C. and 40% RH by driving the car air conditioner, the air blowing amount of the first blower 34 and the second blower 39 is 0.2m ^Three The rotational speeds of the first blower 34 and the second blower 39 are controlled so as to be reduced to 1 / min.
[0066]
Therefore, when the dehumidifying air conditioning unit 43 is operated, the control unit 54 alternately repeats the regeneration mode and the dehumidifying mode as shown in FIG. 7. Both the dehumidified air blown out from the air outlet 50 and the non-dehumidified air are increased in amount compared to the case shown in FIG. 6, and a human body seated in a car parked under a hot summer sun gets a cool feeling immediately. In addition, after the elapse of the predetermined time T1, even if the air flow rate of the first blower 34 and the second blower 39 decreases, the air in the passenger compartment is cooled by the car air conditioner, so that the human body continues to feel cool be able to.
[0067]
In the present embodiment, the second blower 39 is driven only in the regeneration mode in which the dehumidifying means 36 recovers the dehumidifying performance. However, as shown in the time chart of the control sequence shown in FIG. You may make it drive continuously from immediately after a driving | operation start. If it does in this way, since the quantity of the air by the 2nd air blower 39 is also added at the time of dehumidification mode, as the seat main body 31, a total of 0.4 m ^Three The air at a flow rate of / min is blown out from the seating surface, and the feeling of coolness can be further increased by increasing the air volume.
[0068]
In the present embodiment, even when the air in the dehumidifying mode is air of high temperature and low humidity, before the air is blown out from the dehumidifying air outlet 49 of the seat body 31, the skin 37, the cushion material 41, Heat exchange is performed in the seat housing 42, the dehumidified air distribution path 51, and the like, and the dehumidified air at 37 ° C. and 20% RH is obtained.
[0069]
Therefore, as shown in FIG. 9, if a dedicated heat exchanger 61 for cooling high-temperature and low-humidity air is provided between the dehumidifying means 36 and the dehumidifying air outlet 49 of the seat body 31, And can be cooled efficiently. Then, the air becomes low-temperature and low-humidity air and blows out from the dehumidified air outlet 49 of the seat body 31 and flows on the back side of the human body. At that time, by evaporating the sweat on the body surface, the heat of vaporization is taken away to give a cool feeling to the human body and also prevent the feeling of stuffiness. In addition, when a thermal load is applied to the seat constituent member in the seat body 31, heat exchange is performed by the heat exchanger 61 when there are electronic parts and members such as a motor and a board that are affected by performance, reliability, and the like. It is also possible to eliminate the thermal load.
[0070]
In this embodiment, the operation of the dehumidifying air conditioning unit 43 is started after getting on the automobile, but it may be made immediately before getting on. That is, since the automobile is provided with a door lock detection means including a keyless entry system, etc., and a driver detection means such as a door opening / closing detection means and a seating detection means, driving as shown in FIGS. 3 to 5 and FIG. The driver detection means 56 is connected to the control means 54, and the control means 54 stores a program for executing the control sequence shown in FIG. 10, so that the driver detection means 56 approaches the driver's vehicle before starting the engine. Alternatively, the operation of the dehumidifying air-conditioning unit 43 is started when boarding or sitting on the seat is detected.
[0071]
That is, when the driver detection means 56 detects that the driver approaches the vehicle, gets on the vehicle, or is seated on the seat before the engine is started, as shown in FIG. 10, a standby state is established and the exhaust air path switching means 53 is opened. And the heating means 40 is energized to increase the temperature of the adsorbent 35 to desorb the water vapor adsorbed on the dehumidifying means 36, and is released from the exhaust port 47 to the outside of the unit case 44 for adsorption. A regeneration mode operation for recovering the adsorption capacity of the material 35 is performed in advance.
[0072]
Then, when the operation of the dehumidifying air conditioning unit 43 is started and the dehumidifying mode is operated, the energization of the heating means 40 is stopped, and the first air blower 34 and the second air blower 39 are rotated to dehumidify the dehumidified air and the passenger compartment. The air is sent to the seat body 31 and ejected from the dehumidifying air outlet 49 and the air outlet 50, thereby flowing on the back side of the human body and evaporating sweat on the body surface. It gives a feeling and prevents a feeling of stuffiness. After the dehumidifying mode, the regeneration mode and the alternating operation of the dehumidifying mode are repeated for a certain time T1, but only the second blower 39 is continuously rotated from the start of the operation.
[0073]
Therefore, since the dehumidifying means of the air conditioning unit 43 can be regenerated in advance by the driver detecting means 56, the dehumidifying air conditioning unit can always be operated with the capacity of the dehumidifying means maximized, the dehumidifying capacity is large, and the human body is immediately effective immediately after sitting. A great cool feeling can be obtained, and it is extremely useful as an air-conditioning seat device for automobiles. Although the second blower 39 is not operated in the standby state, the second blower 39 is operated from the standby state (regeneration mode), and the suction port of the second blower 39 has a low temperature such as a floor surface. By opening the vehicle interior air at a relatively low temperature from the air outlet 50 of the seat body 31 in advance, the temperature rise of the seating surface of the seat body 31 due to solar radiation or the like is suppressed. It is also possible.
[0074]
In the present embodiment, the air volume (rotation speed) of the dehumidifying first blower 34 in the dehumidifying air conditioning unit 43 is always constant, but may be changed according to the temperature of the air in the passenger compartment.
[0075]
That is, as shown in FIG. 3, the temperature detecting means 55 for detecting the vehicle room temperature is connected to the control means 54, and the control means 54 stores a program for executing the control sequence shown in FIG. 34, the second blower 39, the heating means 40, and the exhaust air path switching means 53 are controlled as shown in FIG.
[0076]
In FIG. 11, the control means 54 performs control to alternately repeat the operation in the regeneration mode and the dehumidification mode as described above with reference to FIG. 6 for a fixed time T1 after the start of the operation of the dehumidifying air conditioning unit 43. The output of the temperature detection means 55 which is detecting the temperature of indoor air is taken in. On the other hand, the air in the passenger compartment is air-conditioned by the driving of the car air conditioner, and the temperature is decreasing. When the temperature detecting means 55 detects that the room temperature has decreased to the set value of 25 ° C., the control means 54. Is 0.4m so far ^Three The air flow rate of the first blower 34 that was rotating at the air flow rate per minute was 0.2 m. ^Three Per minute.
[0077]
Thus, as the time elapses from the start of the operation, the room temperature decreases to the set temperature by the car air conditioner, and this is utilized by the temperature detection means 55 and the control means 54, so that the first dehumidified air is blown. Even if the air volume of the blower 34 is reduced, a sufficient cooling feeling can be obtained, the capacity of the dehumidifying means can be reduced, the dehumidifying air conditioning unit can be downsized, and the air volume of the first blower 34 can be reduced by reducing the air volume. Power consumption can also be kept low. In addition, although it demonstrated by the structure which provided the temperature detection means 55 which detects room temperature, it cannot be overemphasized that the effect similar to a present Example is realizable also as this as a humidity detection means.
[0078]
In this embodiment, one dehumidifying air-conditioning unit 43 is installed in the seat 32 of the seat main body 31. However, only the back 33 of the seat main body 31 or other interior space is used. May be. Thus, it is necessary to have an ability to blow air to both the seat portion 32 and the back portion 33. However, since only one device is required, the number of assembly steps and the number of parts can be reduced, and the cost can be reduced.
[0079]
In addition, in the present embodiment, the air inlet of the first blower 34 of the dehumidifying air-conditioning unit 43 has a low ambient temperature in the passenger compartment such as a place where it is not exposed to direct sunlight during summer parking, such as directly under the seat 32 of the seat body 31. If the configuration is arranged such that the air blown from an air conditioner such as a car air conditioner can be taken in, the air dehumidified by the dehumidifying means 36 can be easily cooled.
[0080]
Further, the dehumidifying air conditioning unit 43 in this embodiment is arranged in the order of the first blower 34, the heating means 40, and the dehumidifying means 36, and the air sent by the first blower 34 is warm air when passing through the heating means 40. Thus, the configuration in which the moisture accumulated in the dehumidifying means 36 is discharged by the warm air and the adsorption capacity is recovered has been described. However, if the adsorbent is supported on the surface of the heating means 40, the adsorbent can be directly heated. As a result, the rate of temperature increase of the adsorbent during regeneration increases. That is, even if the regeneration mode time is shortened, most of the adsorbed water vapor is released, and the adsorption capacity can be recovered in a short time.
[0081]
In the present embodiment, the dehumidifying air-conditioning unit 43 energizes the heating means 40 for recovering the dehumidifying ability of the dehumidifying means 36 only in the regeneration mode to generate heat. However, as shown in FIG. While the exhaust port 47 is closed by the means 53, the heating means 40 is continuously energized to generate heat, and the indoor air sent by driving the first blower 34 is exchanged with the heating means 40 as warm air to obtain a seat body. If the second blower 39 is stopped while being ejected from the dehumidified air outlet 49 of 31, hot air can be ejected from the dehumidified air outlet 49 of the seat body 31. And it can also be used as a heating device when the human body wants to keep warm, such as in winter.
