[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 is a blower, dehumidifying means using the function of causing the adsorbent to absorb the air blown by the blower and dehumidifying the air, and the dehumidified air of the seat. Introduced into the pad portion, and the ventilation passage provided until it further exits the pad portion, and the dehumidifying means exits from the blower and branches in parallel, and a ventilation operation air passage that joins the ventilation passage,
An air passage switching means for switching the air emitted from the blower to pass through either the dehumidifying means or the air passage for blowing operation, and the ejection hole which covers the pad portion and ejects the dehumidified air from the air passage It is composed of the outer skin.

In this way, when the air passage switching means is switched so that the air discharged from the blower passes through the dehumidifying means during operation, the blown air is dehumidified by the dehumidifying means and passes through the ventilation passage to the pad portion. Enters, passes through the branched ventilation passage, and spouts from the spout holes in the epidermis. Since the occupant is seated in the seat, the dehumidified air is blown from the occupant's back to the buttocks and then to the lower limbs. Further, when the dehumidifying performance of the dehumidifying means decreases during the dehumidifying operation, or when the dehumidifying means is not ready for dehumidifying, the air duct switching means sends the air blown from the blower to the dehumidifying means without blowing it. Switch to pass the driving air passage. Therefore, immediately after the start of operation, when there is sweat, it is vaporized and dried, and the heat of vaporization is removed from the skin surface to give a feeling of cooling, eliminating the feeling of sweatiness, and when the dehumidifying air is no longer needed, the dehumidifying performance of the dehumidifying means is reduced. It is possible to perform an operation in which the air flow is lowered and switched to blast only.

According to a second aspect of the present invention, in particular, the air-conditioning seat apparatus according to the first aspect is provided with cooling heat exchange means for cooling the blown air when passing through the dehumidifying means.
The air blown by the blower is dehumidified by the dehumidifying means, and at the same time, it is heated by the heat of condensation in the method using the compression refrigeration cycle and by the heat of adsorption in the adsorption method. Once in the heat exchange means, it is cooled as it passes through this cooling heat exchange means. Although the cooling method of the cooling heat exchange means is not limited, it is generally performed by exchanging heat with the dehumidified air whose temperature has risen in the air in the vehicle compartment. Since the occupant is seated in the seat, dehumidified air that has not risen in temperature is blown from the occupant's back to the buttocks and further to the lower limbs. Therefore, the temperature does not change and it becomes dry air, which blows out to the area of the seat surface in contact with the human body, so that the sweat evaporates and dries, and the heat of vaporization is deprived from the skin surface, giving a feeling of cooling, It eliminates the feeling of slackness and allows you to sit more comfortably.

According to a third aspect of the present invention, particularly in the air-conditioning seat apparatus according to the first aspect, when the dehumidifying performance of the dehumidifying means falls below a predetermined value, the air blown by the air passage switching means is used for blowing operation. By switching to pass through the air passage, when the moisture absorption of the adsorbent used in the dehumidifying means approaches the saturation state during the dehumidifying operation, and the dehumidifying performance decreases and falls below a predetermined value, the air passage changing means is blown. It switches so that the generated wind does not flow into the dehumidifying means and passes through the air passage for blowing operation. And it just blows out from the epidermis via the ventilation passage as a blast. The method for determining the predetermined value of the dehumidification performance for operating the air passage switching means is the dehumidification performance required to eliminate the feeling of sweatiness immediately after the start of operation, and then the dehumidification that feels comfortable only with the wind. It should be set so as to achieve performance.

Therefore, immediately after the start of operation, when there is sweat, the sweat is vaporized and dried with a dehumidifying performance of a predetermined value or more to eliminate the feeling of sweatiness, and when the dehumidified air is no longer needed, the dehumidifying performance of a predetermined value or less is obtained. As a result, it becomes possible to realize efficient operation control.

According to a fourth aspect of the present invention, in the air-conditioning seat apparatus according to the first aspect, the time from the start of the dehumidifying operation is used as an index for the dehumidifying performance of the dehumidifying means to drop below a predetermined value. By setting the timer so that the air passage switching means switches the air discharged from the blower so as to pass through the air passage for blowing operation, the timer sets the time during which the dehumidifying performance of the dehumidifying means falls below a predetermined value. Then, at that time, the air passage switching means switches. Therefore, the air passage switching means easily switches.

According to a fifth aspect of the present invention, in particular, the temperature of the adsorbent is used as the index for the dehumidifying performance of the dehumidifying means to fall below a predetermined value in the air-conditioning seat apparatus according to the first aspect. The air passage switching means switches the air from the blower so that it passes through the air passage for blowing operation.When the adsorbent absorbs moisture during dehumidifying operation, the adsorbent heats up, resulting in dehumidifying performance and adsorbent performance. There is a correlation with the temperature of, and the dehumidifying performance of the dehumidifying means can be estimated by detecting the temperature of this adsorbent. From the correlation between the dehumidifying performance and the temperature of the adsorbent, the exothermic temperature of the adsorbent at the time when the dehumidifying performance of the dehumidifying means falls below a predetermined value is determined, and at that temperature, the air path switching means exits from the blower. The air is switched so as to pass through the ventilation air passage. Then, by detecting the temperature of the adsorbent, it is possible to easily switch the air passage due to the deterioration of the dehumidifying performance of the dehumidifying means.

According to a sixth aspect of the present invention, particularly in the air-conditioning seat apparatus according to the first aspect, the dehumidifying performance of the dehumidifying means is lowered to a predetermined value or less, and the air discharged from the blower passes through the air passage for blowing operation. After the air path switching means has been switched to, the dehumidifying means is allowed to proceed to the regeneration process for recovering the dehumidifying performance, so that when the operation is started, the blown air is dehumidified by the dehumidifying means, and from the ejection holes of the epidermis. Eliminates squirting and discomfort caused by sweat on the occupants. Next, when the dehumidifying performance of the dehumidifying means drops below a predetermined value, the air passage switching means switches the air blown from the air blower so as to pass through the air passage for air blowing operation.
Therefore, the dehumidifying means stops the dehumidifying function and proceeds to the regeneration process for recovering the dehumidifying performance. In the regeneration process, since the dehumidifying means uses an adsorbent, the adsorbent is heated by a regeneration heater,
Releases adsorbed humidity and moisture. When the humidity and moisture have been released, the regeneration heater is stopped and the regeneration process is completed. In this way, the dehumidifying means eliminates the feeling of swelling caused by the sweat of the occupant, and the dehumidifying means can prepare for the next dehumidifying operation at the time when only the air blowing is sufficient.

According to a seventh aspect of the present invention, particularly in the air-conditioning seat apparatus according to the first aspect, in the regeneration process in which the dehumidifying means restores the dehumidifying performance, a part of the air from the blower is diverted to the dehumidifying means. When the dehumidifying performance of the dehumidifying means is reduced to a predetermined value or less due to the provision of the flow dividing means, the air passage switching means switches the air blown from the air blower so as to pass through the air passage for air blowing operation. However, some of the air is diverted. At the same time, the dehumidifying means proceeds to the regeneration process for recovering the dehumidifying performance. In the regeneration process, the adsorbent is heated by the regenerator, but the air diverted by the flow dividing means becomes warm air, which efficiently heats the entire area of the adsorbent.
By appropriately selecting the heat quantity of the regenerating heater and the quantity of air to be blasted separately, the temperature of the air blow becomes the temperature at which the adsorbent releases moisture. Then, in the regeneration process, the heat of the regeneration heater heats the adsorbent to release the adsorbed humidity and moisture, but the heat of the regeneration heater is conveyed to every corner of the adsorbent by the diverted wind. , The regeneration efficiency is improved compared to the case without wind.

According to the eighth aspect of the present invention, particularly in the air-conditioning seat apparatus according to the first aspect, the temperature of the dehumidifying means whose temperature has risen drops to a predetermined value after the regeneration process for recovering the dehumidifying performance of the dehumidifying means is completed. Until the dehumidifying means is stopped by the closing of the diversion means, and the air discharged from the blower continues to be in the state where the air passage switching means is switched so as to pass through the air passage for blowing operation. By doing
Until the temperature of the dehumidifying means whose temperature has risen during the regeneration process decreases to the temperature at which the dehumidified air dries the sweat, the air passage switching means operates by blowing only, no trouble occurs, and usability is improved.

According to a ninth aspect of the present invention, particularly in the air-conditioning seat apparatus according to the first aspect, the temperature of the dehumidifying means whose temperature has risen decreases to a predetermined value after the regeneration process for recovering the dehumidifying performance of the dehumidifying means is completed. , Again, the regeneration process is completed by providing an airtight structure including the flow dividing unit and the air passage switching unit so that the moisture in the apparatus atmosphere does not enter the dehumidifying unit within the time until the dehumidifying operation is performed again. rear,
When the temperature of the adsorbent begins to drop, it changes from absorbing moisture and moisture to absorbing moisture, but since it has an airtight structure including the air passage switching means, it is possible to prevent moisture absorption even if the temperature drops. In the dehumidifying operation, the dehumidifying performance can be maximized.

The invention as defined in claim 10 is particularly claim 1.
By providing the humidity sensor in the means for detecting the dehumidifying performance of the adsorbent of the dehumidifying means of the air-conditioning seat device described, the humidity sensor detects the humidity of the air passing through the dehumidifying means as an example in the dehumidifying operation, and the dehumidifying performance To determine the decrease. Further, in the regeneration process for recovering the dehumidification performance, the regeneration state can be determined, for example, by detecting the moisture moisture released by the adsorbent as the humidity. By providing the humidity sensor in this way, the dehumidifying performance of the dehumidifying means can be quantitatively grasped, and the dehumidifying effect can be further enhanced.

The invention described in claim 11 is particularly claim 1.
By performing the prediction of recovery of the dehumidification performance of the air-conditioning seat device described above in the regeneration process of the adsorbent of the dehumidifying means by a timer that operates at a predetermined time, the heating heat amount of the regeneration heater and the adsorbent of the dehumidifying means The end time of the regeneration process can be roughly estimated from the amount of heat required to release moisture and moisture. If this time is set to the time at which the timer operates, the regeneration process can be completed in an approximate manner, and complicated means should be used. The device becomes simpler.

The invention as defined in claim 12 is particularly defined by claim 1.
The air-conditioning seat device described in the above is placed between the outer skin of the seat and the pad portion, and the air blown from the ventilation passage passes through to blow out from the ejection holes of the outer skin.
By providing a sheet-shaped heater with the
In the heating operation in winter, the sheet-shaped heater is energized to generate heat, and the skin is warmed by heat conduction from the sheet-shaped heater.
Compared to heating with warm air, the temperature of the epidermis becomes higher,
The climb speed will be faster and the comfort will be improved. Further, the sheet-shaped heater does not interfere with the passage of air during dehumidification or blowing operation.

In the regeneration process, the heat of the regeneration heater 34 heats the adsorbent 30 to release the adsorbed humidity and moisture.
At the time when the regeneration process is completed, the temperature of the adsorbent 30 is high.
For example, the temperature is about 120 ° C. for silica gel. At this temperature, the air blown to the dehumidifying means 21 becomes warm air, and the sweat of the occupant cannot be dried. Therefore, from the time when the regeneration process is completed, the flow dividing means 3
5 is closed to stop the shunting air flow to the dehumidifying means 21,
Until the temperature of the adsorbent 30 decreases and the dehumidified air drops to a temperature at which sweat is dried, the state in which the air passage switching means 28 is switched is continued.

As described above, in the present embodiment, the temperature of the adsorbent 30 of the dehumidifying means 21 that has risen during the regeneration process decreases until the dehumidified air reaches the temperature at which sweat is dried.
Since the air passage switching means 28 operates only by blowing air, no trouble occurs and usability is improved.

The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The difference from the first embodiment is that the time until the dehumidifying means 21 recovers its dehumidifying performance after the regeneration process is finished and the temperature of the dehumidifying means 21 is lowered to a predetermined value and the dehumidifying operation is performed again. In order to prevent moisture and water in the apparatus atmosphere from entering the dehumidifying means 21, the flow dividing means 35 and the air passage switching means 28 are made airtight.

The operation and action of the air-conditioned seating device configured as described above will be described below.

After the regeneration process, when the temperature of the adsorbent 30 starts to decrease, it changes from moisture release to moisture absorption. However, since the air passage switching means 28 is included in the airtight structure, the temperature of the adsorbent 30 increases. Prevents moisture absorption even if it decreases.

As described above, in the present embodiment, after the regeneration process is completed, the adsorbent 30 is held in an airtight structure and held until the next dehumidifying operation without absorbing moisture. Can be maximized.

The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The difference from the first embodiment is that the humidity sensor 36 is provided as a means for detecting the dehumidifying performance of the adsorbent 30 of the dehumidifying means 21.

The operation and action of the air-conditioned seating device configured as described above will be described below.

In the dehumidifying operation, as an example, the humidity sensor 36 detects the humidity of the air that has passed through the dehumidifying means 21 and determines whether the dehumidifying performance is deteriorated. Since the dehumidifying performance of the dehumidifying means 21 has deteriorated as the detected humidity rises,
The switching humidity is set in advance, and when the humidity rises to that humidity, switching to the regeneration process is performed. Further, in the regeneration process for recovering the dehumidification performance, the regeneration state can be determined, for example, by detecting the humidity moisture released by the adsorbent 30 as the humidity. In the middle of the regeneration process, the adsorbent 30 releases a large amount of moisture and moisture, so the detected humidity is high, but when the humidity decreases, the regeneration is completed.

As described above, in this embodiment, since the humidity sensor 36 is provided, the dehumidifying performance of the dehumidifying means 21 can be quantitatively grasped, and the dehumidifying effect can be further enhanced.

(Embodiment 11) FIG. 3 is a configuration diagram of an air-conditioning seat apparatus according to an eleventh embodiment of the present invention, and FIG. 4 is a sequence diagram of an operating state.

The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

The difference from the first embodiment is that the recovery of the dehumidification performance is predicted by the timer-31 which operates at a predetermined time in the regeneration process of the adsorbent 30 of the dehumidification means 21.

The operation and action of the air-conditioned seat device configured as described above will be described below.

From the heating amount of the regenerating heater 34 and the heating amount required to release the moisture from the adsorbent 30 of the dehumidifying means 21,
The end time of the regeneration process can be roughly estimated. If this time is set to the time at which the timer-31 operates, the regeneration process can be completed almost in a similar manner.

As described above, in the present embodiment, the end of the reproduction process can be set without using complicated means,
The device becomes simple.

(Embodiment 12) FIG. 1 is a block diagram of an air conditioning seat device according to a twelfth embodiment 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 difference from the first embodiment is that the seat 23 is placed between the skin 25 and the pad portion 24, and the ventilation passage 2
The air blown from the No. 2 air blows out from the jet holes 26 of the skin 25.
The sheet-shaped heater 39 is formed by arranging a heater 38 on a sheet 37 through which the sheet 37 passes for ejecting from the sheet.

The operation and action of the air-conditioned seat device configured as described above will be described below.

In the heating operation in winter, when the sheet-shaped heater 39 is energized to generate heat, the heat is conducted to the skin 25 and the skin 25 is warmed. When the skin 25 warms, it also warms the seated occupant by conduction and radiation. In the dehumidifying or blowing operation, the air blown from the ventilation passage 22 passes through the sheet 37 of the sheet-shaped heater 39 and blows out from the skin 25.

As described above, in the present embodiment, during the heating operation in winter, the sheet-shaped heater 39 is energized to generate heat, and the skin 25 is transferred by heat conduction from the sheet-shaped heater 39. Because of warming, the temperature of the skin 25 is higher and the rising speed is faster than in the case of heating with warm air, and comfort is improved.
Further, the sheet-shaped heater 39 does not hinder dehumidification or passage of air during blowing operation.

As described above, according to the present invention, even when the vehicle is driven in the summer when the temperature of the skin 25 of the seat rises due to the solar radiation, the dehumidified air in the area of the seat surface in contact with the human body. As the sweat evaporates, the sweat evaporates and dries, and the heat of vaporization is deprived from the skin surface, giving a cooling sensation, eliminating the stuffiness of sweat, and allowing the user to sit comfortably.
