Description

  The present invention provides a comfortable state quickly to the human body even when the outdoor thermal environment is uncomfortable, for example, in a car or an office chair of an automobile. The present invention relates to a seat device having an air conditioner that can provide a comfortable seating feeling.

Conventionally, as this type of air-conditioning seat device, as shown in FIG. 5, an air flow path 2 is formed in a support member 1 inside the seat, the outside of the support member 1 is covered with a porous member 3, and a small hole is formed. There is disclosed a technique in which a porous seat cover 4 such as an open leather surrounds the porous member 3 with respect to the support member 1 and blows out conditioned air 8 in which temperature and humidity are harmonized (for example, see Patent Document 1). ).
JP-T 9-505499

  However, as shown in FIG. 5, in the conventional air-conditioning seat apparatus, since the small holes of the seat cover 4 are communicated with each other by the flow path 2, the blown air is in contact with the human body when seated. It does not flow out of the hole of the seat cover 4 and flows out of the hole in the part where the human body is not in contact. Therefore, even if air of low humidity is blown, dry air is not sent to the human body in contact with the seat, so that there is a problem that sweat is not sufficiently vaporized and the stuffiness is not eliminated. Further, at the time of sitting, since the support member 1 is crushed when pressure is applied, there is a concern that the flow path 2 is crushed and the wind does not reach the entire seat. In addition, because the air of the blower blows out from the small hole of the seat cover, the small hole of the seat cover affects the design, for example, it is not possible to provide the small hole of the seat cover in a place where you do not want to blow out the air of the blower, There was a problem that design restrictions were large.

  The present invention solves the above-mentioned conventional problems, and in an air-conditioning seat device, air is effectively ejected without impairing the design, and problems such as stuffiness are eliminated by the synergistic effect of air blowing and a planar heating element. The purpose is to improve the feeling of use.

  In order to solve the above-described problems, an air-conditioning seat device according to the present invention includes a seat support member having an air flow path, a blower disposed at an appropriate position of the support member, and an air flow path positioned above the support member. An air layer member that temporarily stores air supplied from the air layer member, and a non-breathable planar member that covers the air layer member and has an air outflow opening that guides outflow of air from the air layer; A seat cover surrounding the planar member and having an air outlet is provided, and air quality adjusting means for adjusting the quality of air blown from the blower to the air flow path is provided.

  With the above configuration, since the non-breathable planar member that covers the air layer member and has an air outflow opening that controls the outflow of air from the air layer is disposed, the air layer member can be formed to have a large volume. And the entire seat can be filled with air from the air flow path. In other words, by blowing the air conditioned by the air quality adjusting means to the air layer member, the entire seat can be maintained in a state of being filled with conditioned air, and the conditioned air can be ejected from any part of the seat Can be ejected from the air outflow opening of a non-breathable planar member provided at a proper position through the jet outlet of the seat cover, and adjusted by the position and shape of the air outflow opening of the planar member. In addition, it is possible to blow out the conditioned air that is optimal for conditions such as the seating state in accordance with the design and shape of the seat. Therefore, since the air layer member is not affected by the air ejection conditions, it can be made common even if the seat design changes, and the air ejection position can be regulated by the air outlet opening of the planar member. The design of the cover can also increase the degree of freedom. In addition, since the planar member covers the air layer member, even when a load such as a seating is applied, the air layer member is entirely loaded by the planar member and the amount of deformation is reduced. The load resistance and durability can be increased by the synergistic effect of the member and the air layer member.

  Furthermore, since it has an air outflow opening of the planar member, a construction method was used in which a heat-meltable adhesive material was interposed between the seat cover and any of the planar member and the air layer member and was adhered to the seat cover with steam. In some cases, even a non-breathable planar member allows steam to pass through the air outlet opening of the planar member, and the vicinity of the air outlet opening of the planar member can be firmly bonded.

  The air-conditioning seat device of the present invention can regulate the ejection of air conditioned by the air quality adjusting means of the air layer member by the air outflow opening of the planar member, and the air ejection condition of the air layer member is adjusted. Because it is not affected, it can be shared even if the seat design changes, etc., and the conditioned air can be blown out optimally for the seating condition etc. according to the seat design and shape Thus, it is possible to control the ejection of conditioned air with a simple configuration, and it is possible to improve the feeling of use such as stuffiness due to the synergistic effect of the air blowing and the planar heating element.

  According to a first aspect of the present invention, there is provided a seat support member having an air flow path, an air layer member that is located above the support member and forms a layer of air supplied from the air flow path, and air that covers the air layer member A non-breathable planar member having an air outflow opening that guides the outflow of air from the layer, and a seat cover that surrounds the planar member and has an air outlet, and is blown to the air flow path by a blower The air quality adjusting means for adjusting the air quality is provided.

  And since the non-breathable planar member having an air outflow opening that covers the air layer member and controls the outflow of air from the air layer is disposed, the air layer member can be formed with a large volume, The entire seat can be filled with air from the air flow path. In other words, by blowing air adjusted by the air quality adjusting means to the air layer member, the entire seat can be held in a state of being filled with conditioned air, and conditioned air can be ejected from any part of the seat. Can be ejected from the air outflow opening of the non-breathable planar member provided in the proper position through the jet outlet of the seat cover, and can be adjusted by the position and shape of the air outflow opening of the planar member. In addition, it is possible to cause the conditioned air to be blown out optimally for conditions such as the seating state in accordance with the design and shape of the seat. Therefore, since the air layer member is not affected by the air ejection conditions, it can be made common even if the seat design changes, and the air ejection position can be regulated by the air outlet opening of the planar member. The design of the cover can also increase the degree of freedom. In addition, since the planar member covers the air layer member, even when a load such as a seating is applied, the air layer member is entirely loaded by the planar member and the amount of deformation is reduced. The load resistance and durability can be increased by the synergistic effect of the member and the air layer member.

  Furthermore, since it has an air outflow opening of the planar member, a construction method was used in which a heat-meltable adhesive material was interposed between the seat cover and any of the planar member and the air layer member and was adhered to the seat cover with steam. In some cases, even a non-breathable planar member allows steam to pass through the air outlet opening of the planar member, and the vicinity of the air outlet opening of the planar member can be firmly bonded.

  In the second invention, a planar heating element is disposed on the planar member.

  When the air adjusted by the air quality adjusting means is blown by the blower to heat the air, the rising time of the air quality adjusting means and the heat capacity of the air flow path and the air layer member heated by the air quality adjusting means are increased. It takes time to rise and it takes time to get a feeling of heating, and there is a concern that the feeling of use at the beginning of use is bad, but since a sheet heating element is arranged on the sheet member, cover the seat Thus, the user can be directly heated by heat conduction, and a feeling of heating can be quickly felt, thereby improving the feeling of use. In addition, if the user uses heating only with a sheet heating element for a long time, the user may get steamed even in winter, but if the air adjusted by the air quality adjustment means is blown by a blower, the user's The feeling of stuffiness can be eliminated and the feeling of use is improved.

  In other words, in addition to being indirectly heated by the air quality adjusting means, by directly heating with the sheet heating element, it becomes possible to obtain quick heat and to eliminate stuffiness, and to be synergistic. The feeling of use can be greatly improved.

  In a third aspect of the invention, the planar heating element disposed on the planar member is configured as a PTC heater having a self-temperature adjusting function in which an electrode and a heating element material are disposed on an electrically insulating substrate.

  Since the planar heating element is a PTC heater having a self-temperature adjusting function, the heating part is planar, the heating area is wide, and the heating surface temperature can be lowered, so that safety is improved and comfort is improved. Can be planned. For example, if the planar heating element is a linear heater, the heating part is linear, the heating area is narrow, the heating surface temperature is increased, and if the average surface temperature is set to 40 ° C., the heating part is locally The temperature must be controlled at 70 to 120 ° C., and a temperature controller such as a thermo is required, which complicates the structure.

  In addition, the temperature is locally high, causing problems such as burns, and the temperature distribution is uneven, so comfort is impaired, and the temperature difference from the surroundings is large, so it may not be used. There was a problem that the heat loss in the part not touched by humans was large and the power consumption was large. On the other hand, when the planar heating element is a PTC heater, the heating part is planar and has a large heating area, and when the average surface temperature is set to 40 ° C., the heating part may be 45 to 50 ° C. Since it also has an adjustment function, a temperature controller such as a thermo is unnecessary, and the structure is simplified. In addition, since the temperature is low, there is no need to worry about problems due to heat generation such as burns, the temperature distribution is uniform, so comfort is good, and because the temperature difference from the surroundings is small, there is little heat loss and low power consumption. become able to.

  In a fourth aspect of the invention, air is sent from the air flow path after a predetermined time has elapsed from the start of energization of the planar heating element disposed on the planar member.

  When the air adjusted by the air quality adjusting means is blown by the blower to heat the air, the rising time of the air quality adjusting means and the heat capacity of the air flow path and the air layer member heated by the air quality adjusting means are increased. Since it takes time to rise, there is a concern that the initial blowing temperature does not reach the temperature at which the warmth is felt, but rather has a feeling of coolness. However, since air is sent from the air flow passage after a predetermined time has elapsed from the start of energization of the planar heating element, the planar heating element is not cooled by the air blown by the blower, and is quickly heated. The air of the air layer member can be warmed with the sheet heating element while maintaining the temperature, and the air whose temperature has risen sufficiently can be sent at a stretch, so that the user can feel a sense of heating more. , You will be able to greatly improve the feeling of use synergistically.

  5th invention is set as the structure which sent air from an air flow path intermittently at the time of electricity supply of the planar heating element arrange | positioned at the planar member.

  Since air is intermittently sent from the air flow path when the planar heating element disposed on the planar member is energized, the air in the air layer member heated by the planar heating element is also heated by the user. In addition, the heating by the planar heating element and the heating by the air blown by the blower are intermittently applied, so that the user can feel a sense of heating more.

  In the sixth aspect of the invention, the sheet heating element disposed on the sheet member and the blower that sends air from the air flow path are alternately energized to send air from the air flow path intermittently.

  Since the sheet heating element disposed on the sheet member and the blower that sends air from the air flow path are alternately energized to intermittently send air from the air flow path, the intermittent invention of the fourth invention In addition to improving the feeling of heating obtained by sending air, the sheet heating element and the blower are not energized at the same time, so that the maximum electric capacity becomes one of them, and the maximum electric capacity can be reduced.

  7th invention is set as the structure which arrange | positioned the humidity adjustment means which adjusts the humidity of the air ventilated with the air blower in the flow path of air.

  Then, the air is dehumidified by, for example, a dehumidifying means made of an adsorbent such as silica gel or zeolite, and the indoor air is dehumidified and blown out from the jet outlet of the seat body to vaporize the sweat on the body surface. Give a feeling. Further, after the sweat is evaporated, the feeling of stuffiness is prevented by dehumidifying the perspiration released from the human body. Furthermore, an appropriate warm feeling can be given by supplying heat to the human body by heat conduction with a heating element provided on the skin part of the seat body. An air conditioning environment in which the human body is comfortable can be realized by arbitrarily setting the cool feeling and the warm feeling according to personal preference.

  In an eighth aspect of the invention, the humidity adjusting means is made of an adsorbent that dehumidifies by adsorption, and includes a heating means for heating the adsorbent.

  And, as it has a dehumidifying material such as zeolite or silica gel that uses adsorption as a dehumidifying means, it does not require dew condensation treatment compared to the dehumidifying method using Peltier elements etc. Even when the temperature is low, dehumidification is possible, and the feeling of stuffiness felt when sitting for a long time even in winter can be prevented. Further, since the heating means for heating the adsorbent is provided, the dehumidifying material can be regenerated, stable dehumidification can be performed over a long period of time, and a comfortable air-conditioning environment can be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view according to Embodiment 1 of the present invention, and FIG. 2 is a schematic view of a PTC heater used in the air-conditioning seat device.

  An air flow path 13 is formed in the support member 11 forming the skeleton of the seat, and air quality adjusting means 12 for adjusting the quality of air is disposed in the air flow path 13. The air quality adjusting means 12 for adjusting the air quality of the seat is provided on the cold junction side of the blower 14 such as a sirocco fan located at the lower part of the seat and the Peltier element 15 for dehumidifying the air blown by the blower 14. One heat exchanger 16, a second heat exchanger 17 on the hot junction side, a dehumidifying means 18 for condensing water vapor with the first heat exchanger 16, a drain pipe 19 and a drain pipe for collecting water condensed by the dehumidifying means 18 It is formed from an evaporating dish 20 for evaporating the water collected at 19.

  Above the support member 11, there is disposed an air layer member 21 that is formed of a porous body having elasticity and high air permeability, and forms an air layer by collecting air from the air flow path 13. As a non-breathable planar member that covers the air layer member 21 and has an air outflow opening 22a that regulates the outflow of air from the air layer, an electrode 24 and a heating element material 25 are disposed on a non-breathable electrical insulating substrate 23. A provided PTC heater 22 having a self-temperature adjusting function is disposed, and a seat cover 26 such as a skin surrounding the PTC heater 22 and having an air outlet 26a is disposed.

  In the above configuration, the seat is heated by supplying air from the blower 14 through the air flow path 13 after the PTC heater 22 is energized, and after being stabilized, the blower is turned on when the PTC heater 22 is energized. Air is intermittently sent from 14 to the air layer member 21 via the air flow path 13.

  In addition, the air blown by the blower 14 is dehumidified by the humidity adjusting means 12, then guided to the air layer member 21 through the air flow path 13, and further the air outflow opening of the PTC heater 22 covering the air layer member 21. It is jetted from the jet outlet 26a of the seat cover 26 through 22a.

  Next, the blown air reaches the clothes and the skin surface, and the dry air vaporizes sweat and prevents the stuffiness. The air layer member 21 is compressed by the weight of the human body at the time of sitting, but the air layer member 21 is a porous body having elasticity and high air permeability, and is configured to have a deformation amount of 10% or less. Air permeability can be maintained. Therefore, even if the air outflow opening 22a is provided at the seating position of the collar portion that is most compressed and deformed when seated, the dehumidified air can be blown to the collar portion, thereby realizing a seat that prevents a feeling of stuffiness of the collar portion.

  Here, since the non-breathable PTC heater 22 that covers the air layer member 21 and has an air outflow opening 22a that controls the outflow of air from the air layer member 21 is disposed, the air layer member 21 has a large volume. The entire seat can be filled with air from the air flow path 13. That is, by blowing air to the air layer member 21, the entire seat can be held in a state of being filled with air, air can be ejected from any part of the seat, and a non-breathable PTC heater provided at an appropriate position The air outlet opening 22a of the seat cover 26 can be ejected from the air outlet opening 22a of the seat cover 26, and the position and shape of the air outlet opening 22a of the PTC heater 22 can be adjusted to match the design and shape of the seat. Air can be ejected optimally for conditions such as the seating state. Therefore, since the air layer member 21 is not influenced by the air ejection conditions, it can be made common even if the seat design changes, and the air ejection position can be regulated by the air outflow opening 22a of the PTC heater 22. The design of the seat cover 26 can also increase the degree of freedom. In addition, since the PTC heater 22 is configured to cover the air layer member 21, even if a load such as seating is applied, the air layer member 21 is entirely loaded by the PTC heater 22, and the deformation amount is reduced. The load resistance and durability can be increased by the synergistic effect of the PTC heater 22 and the air layer member 21.

  Further, in the case of using a method in which the seat cover 26 and the PTC heater 22 and the air layer member 21 are bonded with steam from the seat cover 26 via a heat-meltable adhesive material, the PTC heater 22 Steam passes through the air outflow opening 22a and can be firmly bonded.

  In addition, when the air adjusted by the air quality adjusting means 12 is blown by the blower 14 to be heated, the rise time of the air quality adjusting means 12 and the air flow path and the air layer member heated by the air quality adjusting means 12 Although the heat capacity of 21 is large and it takes time to raise the temperature, it takes time to obtain a feeling of heating, and there is a concern that the feeling of use at the beginning of use is bad, but a planar heating element is arranged in the PTC heater 22 Therefore, it becomes possible to heat the user directly by heat conduction through the seat cover 26, so that a feeling of heating can be quickly felt, and the feeling of use is improved. In addition, if the user uses the PTC heater 22 alone for a long time, the user may get steamed even in winter, but if the air adjusted by the air quality adjusting means 12 is blown by the blower 14, the user The feeling of stuffiness can be eliminated and the feeling of use is improved.

  In other words, in addition to heating indirectly with the air quality adjusting means 12, heating directly with the sheet heating element can provide quick heat and can eliminate the stuffiness, synergistically. Thus, it is possible to greatly improve the feeling of use.

  Since the planar heating element is a PTC heater 22 having a self-temperature adjusting function, the heating part is planar, the heating area is wide, and the heating surface temperature can be lowered, so that safety is improved and comfort is improved. Improvement can be achieved. For example, if the planar heating element is a linear heater, the heating part is linear, the heating area is narrow, the heating surface temperature is increased, and if the average surface temperature is set to 40 ° C., the heating part is locally The temperature must be controlled at 70 to 120 ° C., and a temperature controller such as a thermo is required, which complicates the structure. In addition, the temperature is locally high, causing problems such as burns, and the temperature distribution is uneven, so comfort is impaired, and the temperature difference from the surroundings is large, so it may not be used. There was a problem that the heat loss in the part not touched by humans was large and the power consumption was large. On the other hand, when the planar heating element is the PTC heater 22, when the heating part is planar and the heating area is wide and the average surface temperature is 40 ° C, the heating part may be 45 to 50 ° C. Since it also has a temperature adjustment function, a temperature controller such as a thermo is unnecessary, and the structure is simplified. In addition, since the temperature is low, there is no need to worry about problems due to heat generation such as burns, the temperature distribution is uniform, so comfort is good, and because the temperature difference from the surroundings is small, there is little heat loss and low power consumption. become able to.

  Further, when the air adjusted by the air quality adjusting means 12 is blown by the blower 14 for heating, the rise time of the air quality adjusting means 12 or the air flow path 13 and the air layer member 21 heated by the air quality adjusting means 12 are used. Since the heat capacity is large and it takes time to increase the temperature, the initial blowing temperature does not reach the temperature at which it feels warm, but rather there is a concern that it feels cool. However, since the air is sent from the air flow path 13 after a predetermined time has elapsed from the start of energization of the planar heating element, the PTC heater 22 is not cooled by the air blown by the blower 14, and the speed is increased. The air of the air layer member 21 can be warmed by the PTC heater 22 while maintaining the thermal property, and the air having a sufficiently high temperature can be sent at a stretch, so that the user can feel a sense of heating more. As a result, the usability can be greatly improved synergistically.

  Further, since air is intermittently sent from the air flow path 13 when the PTC heater 22 is energized, the air in the air layer member 21 heated by the PTC heater 22 can also be used for heating the user. At the same time, heating by the PTC heater 22 and heating by the air blown by the blower 14 are intermittently applied, and the user can feel a sense of heating more.

  The same effect can be obtained even if the dehumidifying means is installed in front of the blower 14 outside the seat body and blows the air dehumidified by the blower 14, and the compression refrigerator is used instead of the Peltier element. The same effect can be obtained by using.

(Embodiment 2)
FIG. 3 is a cross-sectional view during the regeneration mode operation of Embodiment 2 of the present invention, and FIG. 4 is a cross-sectional view during the dehumidification mode operation. Embodiment 1 Components having the same reference numerals have the same structure and description thereof is omitted. The difference from Embodiment 1 is that the dehumidifying means 31 has a dehumidifying material such as zeolite or silica gel using an adsorption action, and the dehumidifying material of the dehumidifying means 31 is heated by convection, radiation, or conduction. A heating means 32 such as an electric heater is provided, and a discharge port 33 communicating from the dehumidifying means 31 to the outside of the seat body, and the air flow path 13 is closed when the discharge port 33 is opened, and an air flow path when the discharge port 33 is closed. 13 is provided with a discharge air path switching means 35 such as a damper driven by a stepping motor 34 for opening 13.

  In addition, the sheet heating element disposed in the PTC heater 22 and the blower 14 that sends air from the air flow path 13 are configured to alternately energize and send air from the air flow path 13 intermittently.

  In the above configuration, as shown in FIG. 3, the dehumidifying means 31 performs a regeneration mode operation for recovering the dehumidifying performance. The discharge air path switching means 35 is set to a position where the discharge port 33 is opened, the heating means 32 is driven, and the dehumidifying blower 14 having a flow rate of 0.2 m3 / min is first stopped for t1 (20 seconds) and then driven for t2 (1 second). Let In the case of the silica gel adsorbent, when the adsorbent is heated to 120 ° C., water vapor begins to desorb from the adsorbent, but the generated water vapor is discharged from the outlet 33 into the vehicle compartment by the blower 14. In this case, the heat generated by the heating means 32 is transmitted to the adsorbent surface, but when the adsorbent 1 surface is at a low temperature, the blower 14 is not driven, so the adsorbent surface temperature rises quickly and the adsorbent rapidly Is detached. In addition, since the surface temperature of the adsorbent becomes higher when it is blown intermittently than when it is blown at a flow rate of 0.01 m3 / min in a steady state, the amount of heat transfer to the inside of the adsorbent is increased according to Fourier's law, and the regeneration time is increased. Is early. In addition, the apparatus can be configured simply because there is no need to adjust the air flow rate.

  Note that after the regeneration mode is completed, a dehumidifying mode operation as shown in FIG. 4 is performed. In the dehumidifying mode, the discharge air path switching means 35 is set to the position where the discharge port 33 is closed, and the blower 14 is driven. The air (35 ° C., 55% RH) in the passenger compartment sent to the dehumidifying means at a flow rate of 0.2 m 3 / min by the blower 14 is adsorbed by the adsorbent of the dehumidifying means 31 to reduce the humidity and generate heat due to the adsorption heat. (48 ° C., 18% RH) as high-temperature and low-humidity air, led to the air passage 25, through the through-hole 16, blown out from the spout 26a14 of the epidermis 15 and ejected to the human body surface and clothes, The dry air that reaches the skin surface can evaporate perspiration and prevent stuffiness.

  In this way, for example, the room air is dehumidified using the dehumidifying means 31 made of an adsorbent such as silica gel or zeolite, and blown out from the jet outlet 26a of the seat body, and the body surface is vaporized to quickly evaporate the heat of vaporization. Gives a cool feeling. Further, after the sweat is evaporated, the feeling of stuffiness is prevented by dehumidifying the perspiration released from the human body. Furthermore, an appropriate warm feeling can be given by supplying heat to the human body by heat conduction with a heating element provided on the skin part of the seat body. An air conditioning environment in which the human body is comfortable can be realized by arbitrarily setting the cool feeling and the warm feeling according to personal preference.

  Since the dehumidifying means 31 has a dehumidifying material such as zeolite or silica gel using an adsorption action, compared to a dehumidifying method using a Peltier element or the like, there is no need for treatment of condensed water, and in winter Even when the dew point is low, dehumidification is possible, and the feeling of stuffiness when sitting for a long time in winter can be prevented. Furthermore, since the heating means 32 for heating the adsorbent is provided, it is possible to regenerate the dehumidifying material, so that stable dehumidification can be achieved over a long period of time, and a comfortable air-conditioning environment can be realized. .

  In addition, since the PTC heater 22 and the blower 14 that sends air from the air flow path 13 are alternately energized to send air intermittently from the air flow path 13, the air layer member 21 heated by the PTC heater 22. Air can be used for the heating of the user, and the heating by the PTC heater 22 and the heating by the air blown by the blower 14 are intermittently applied, so that the user can feel a sense of heating more. In addition to this, since the sheet heating element and the blower 14 are not energized at the same time, the maximum electric capacity becomes either one, and the maximum electric capacity can be reduced.

  In the configuration in which the adsorbent is supported on the surface of the heating means 32 such as a stainless steel mesh as the dehumidifying means, the regeneration mode time may be about 30 seconds, and the dehumidified air may be stopped for a short time in the regeneration mode. .

  As described above, according to the air-conditioning seat device of the present invention, the synergistic effect of the air blowing and the planar heating element can provide a seating environment of hot and cold heat that matches the individual characteristics and eliminates stuffiness. The present invention can also be applied to vehicles such as car seats used, heating appliances, and heating appliances.
