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.

As a conventional air-conditioning seat apparatus of this type, 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. A device is disclosed 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 the temperature and humidity are harmonized (see, for example, 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, and an air layer that is located above the support member and temporarily accumulates air from the air flow path. Forming an air layer member, a non-breathable planar member that covers the air layer member and has an air outflow opening that guides the outflow of air from the air layer member, and an air outlet that surrounds the planar member. And a flexible pad that has a flow path means that covers the planar member and is positioned between the seat cover and allows air from the air outflow opening to pass therethrough .

  With the above configuration, the air layer member is formed with a large volume because the non-breathable planar member having an air outflow opening that covers the air layer member and guides the outflow of air from the air layer member is disposed. And the entire seat can be filled with air from the air flow path. In other words, since the air layer is formed by temporarily storing the air supplied from the air flow path by the air layer member, the entire seat can be held in a state of being filled with air, and air can be supplied from any part of the seat. Can be ejected from the air outlet opening of the non-breathable planar member provided at a proper position through the outlet of the seat cover, and the air outlet opening of the planar member. By appropriately adjusting the position and shape of the seat, it is possible to eject air that is optimal for conditions such as a 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 used in common even if the seat design changes, and the air outlet position of the planar member can regulate the air ejection position. The design can also increase the degree of freedom of choice. 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 from the air layer member by the air outflow opening of the planar member, and the air layer member is not affected by the air ejection conditions, so the seat design and the like change. However, it is possible to make the air jet optimal for the seating condition and other conditions according to the seat design and shape, and to control the air jet with a simple configuration. 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, a blower disposed at an appropriate position of the support member, an air flow path for flowing air from the blower, and an air flow path located above the support member and supplied from the air flow path. An air layer member for temporarily storing air to form an air layer, a non-breathable planar member having an air outflow opening that covers the air layer member and guides outflow of air from the air layer member, A seat cover that surrounds the planar member and has an air outlet, and a flexible pad that covers the planar member and is positioned between the seat cover and has flow passage means that allows air from the air outflow opening to pass therethrough. It is as a configuration provided .

  And since the non-breathable planar member having an air outflow opening that covers the air layer member and guides the outflow of air from the air layer member 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 to the air layer member, the entire seat can be held in an air-filled state, and air can be ejected from any part of the seat. It can be ejected from the outflow opening through the outlet of the seat cover, and can be adjusted by the position and shape of the air outflow opening of the planar member, and is optimal for conditions such as the seating state according to the seat design and shape It becomes possible to make the air blow out. Accordingly, 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 outlet position of the planar member can regulate the air ejection position. The design 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 addition, since a flexible pad, for example, a highly breathable thin sponge-like pad is disposed between the planar member and the seat cover, the strength of the non-breathable planar member is increased. Even if a material that is slightly inflexible is used, the flexibility can be compensated with a flexible pad, the degree of freedom in selecting the material of the planar member can be increased, and the feeling of use when sitting is improved. Will be able to. Further, since the pad is located between the jet outlet of the seat cover and the air outflow opening of the planar member, the air outflow opening of the planar member cannot be seen from the surface of the seat cover, and the appearance is improved.

In the second invention, the air layer member is configured to be a porous body having elasticity and high air permeability.

  And since the air layer member is a porous body having elasticity and high air permeability, for example, a sponge-like porous body having a large pore diameter, when air is blown to the air layer member, the air layer member is uniformly filled. Thus, the air can be stably ejected from the ejection port of the seat cover through the air outflow opening of the planar member. Further, the air layer member does not require an air flow path or a column beam, and the structure can be easily formed.

In a third aspect of the present invention, a planar heating element is disposed on the planar member.

  And since the planar heating element is disposed on the planar member, when heating is performed using the air blown by the blower, the rise time, the air flow path and the heat capacity of the air layer member increase greatly. 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 planar heating element is arranged on the planar member, 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 for a plane heating element for a long time, the user may get steamed even in winter, but the feeling of stuffiness of the user can be eliminated by blowing air with a blower As a result, the feeling of use is improved.

  In other words, in addition to indirectly heating using air blown by a blower, heating directly with a planar heating element can provide rapid heating and eliminate stuffiness. As a result, the usability can be greatly improved synergistically.

According to a fourth aspect of the present invention, the planar heating element disposed on the planar member is 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 the fifth invention, the seat body has a back portion and a seat portion, and the back portion and the seat portion have different arrangement patterns of the planar heating elements.

When seated, the shape of the skin part contacting the human body is different between the back part of the seat body and the seat part, but by adopting an optimal pattern of planar heating elements for each, for example, the thigh, neck, shoulder, etc. For example, the pattern of the planar heating elements is arranged in a place where a feeling of warmth is easily felt, so that the heat generation is large, and the feeling of warmth can be effectively obtained with less energy.

  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 of an air conditioning seat device 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 blower 12 is disposed at an appropriate position of the support member 11 forming the skeleton of the seat, and an air flow path 13 for sending air blown by the air blower 12 is provided in the vicinity. Above the support member 11, an air layer member 14 is provided which is made of a porous material having elasticity and high air permeability, and forms an air layer by accumulating air from the air flow path 13. A PTC heater 16 is disposed as a non-breathable planar member that covers the air layer member 14 and has an air outflow opening 15 that guides outflow of air from the air layer member 14. The PTC heater 16 has a self-temperature adjusting function in which an electrode 18 and a heating element material 19 are disposed on a non-breathable electrically insulating substrate 17. The PTC heater 16 surrounds the PTC heater 16 so as to cover the air outlet. A seat cover 20 such as a skin having 20a is disposed, and the PTC heater 16 is covered and between the seat cover 20 and the air from the air outflow opening 15 is highly air permeable and thin. A flexible pad 21 made of a porous material is provided.

  In the above configuration, the seat is heated by supplying air from the blower 12 through the air flow path 13 after a predetermined time has passed after the PTC heater 16 is energized. The air is guided to the air layer member 14 through the passage 13 and is further ejected from the jet outlet of the seat cover 20 through the air outflow opening 15 of the PTC heater 16 covering the air layer member 14. The blown air reaches the clothes and the skin surface, thereby vaporizing sweat and preventing a feeling of stuffiness. When seated, the air layer member 14 is compressed by the weight of the human body, but the air layer member 14 is a porous body having elasticity and high air permeability, and is configured to have a deformation amount of 10% or less. Therefore, air permeability can be maintained. Therefore, even if the air outflow opening 15 is provided at the seating position of the collar part that is most compressed and deformed when seated, the dehumidified air can be blown to the collar part, thereby realizing a seat that prevents the sultry feeling of the collar part.

  Here, since the non-breathable PTC heater 16 that covers the air layer member 14 and has the air outflow opening 15 that guides the outflow of air from the air layer member 14 is disposed, the air layer member 14 has a large volume. The entire seat can be filled with air from the air flow path 13. In other words, by blowing air to the air layer member 14, the entire seat can be held in a state of being filled with air, and air can be ejected from any part of the seat, and a non-breathable PTC heater provided in a proper position 16 can be ejected from the air outlet 15 of the seat cover 20 through the outlet of the seat cover 20, and can be adjusted by the position and shape of the air outlet 15 of the PTC heater 16, and can be seated according to the design and shape of the seat. It becomes possible to eject air that is optimal for conditions such as conditions. Therefore, since the air layer member 14 is not affected by the air ejection conditions, it can be made common even if the seat design changes, and the air ejection position of the PTC heater 16 can regulate the air ejection position. The design of the seat cover 20 can also increase the degree of freedom. Further, since the PTC heater 16 is configured to cover the air layer member 14, even if a load such as seating is applied, the air layer member 14 is entirely loaded by the PTC heater 16, and the deformation amount is reduced. The load resistance and durability can be increased by the synergistic effect of the PTC heater 16 and the air layer member 14.

Further, since the PTC heater 16 has the air outflow opening 15, the seat cover 20 is bonded to the seat cover 20 with steam by interposing a hot-melt adhesive material between any one of the PTC heater 16 and the air layer member 14. In the case of using the construction method, even the non-breathable PTC heater 16 allows steam to pass through the air outflow opening 15 of the PTC heater 16, and the vicinity of the air outflow opening 15 of the PTC heater 16 is firmly bonded. become able to.

  Since a flexible pad 21, for example, a thin sponge pad 21 having high air permeability, is disposed between the PTC heater 16 and the seat cover 20, the strength of the non-air-permeable PTC heater 16 is increased. Therefore, even if a material that is slightly inflexible is used, flexibility or the like can be supplemented by the flexible pad 21, and the degree of freedom in selecting the material of the PTC heater 16 can be increased. Can be improved. Further, since the pad 21 is positioned between the jet outlet of the seat cover 20 and the air outflow opening 15 of the PTC heater 16, the air outflow opening 15 of the PTC heater 16 cannot be seen from the surface of the seat cover 20, and the appearance is improved. .

  Further, since the air layer member 14 is a porous body having elasticity and high air permeability, for example, a sponge-like porous body having a large pore diameter, when air is blown to the air layer member 14, the air is uniformly distributed to the air layer member 14. The air layer member 14 can be stably ejected from the ejection port of the seat cover 20 through the air outflow opening 15 of the PTC heater 16. The structure can be easily formed.

  Since the PTC heater 16 is provided as a planar member, when heating is performed using the air blown by the blower 12, the rise time, the air flow path, and the heat capacity of the air layer member 14 are increased. Although it takes time to ascend and it takes time to obtain a feeling of heating, there is a concern that the feeling of use at the beginning of use is bad, but since the PTC heater 16 is provided, it is directly connected via the seat cover 20. The user can be 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 the PTC heater 16 alone for a long time, the user may get steamed even in winter, but the user's feeling of stuffiness can be eliminated by blowing air with the blower 12. As a result, the feeling of use is improved.

  That is, in addition to indirectly heating using the air blown by the blower 12, heating is directly performed by the PTC heater 16, so that quick heat can be obtained and the feeling of stuffiness can be eliminated. As a result, the usability can be greatly improved synergistically.

  Also, as shown in FIG. 2, the planar heating element is a PTC heater 16 having a self-temperature adjusting function, so the heating part is planar, the heating area is wide, and the heating surface temperature can be lowered, so that safety is improved. As well as improving, comfort can be improved. 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 16, 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.

  In the first embodiment, the PTC heater 16 is used as the planar member. However, the PTC heater 16 may be a string-wire heater or may not use a heater. Further, both the seat and the back of the seat are used. The air layer member 14, the PTC heater 16, and the like are provided for air conditioning. However, either one of them may be used, and the configuration of each of the other parts is within the range that achieves the object of the present invention. It may be a thing.

FIG. 3 is a perspective view of the air-conditioning seat device according to Embodiment 2 of the present invention. In addition, the thing of the same code | symbol as Embodiment 1 has the same structure, and abbreviate | omits description.

  The second embodiment is different from the first embodiment in that the PTC heaters 33 and 34 are arranged differently on the seat portion 31 and the back portion 32 of the seat as shown in FIG. That is, as shown in FIG. 3, the PTC heater 33 of the seat portion 31 is provided so as to be wide on the thigh when seated, and the PTC heater 34 of the back portion 32 is provided on the skin portion 35 that contacts the back and shoulder.

  In the above configuration, since the PTC heater 33 is disposed in a place where a thermal sensation is felt, such as a thigh where the subcutaneous fat is thinner than a portion where the subcutaneous fat is thick, such as the buttocks, a thermal sensation can be obtained effectively. Further, the PTC heater 34 of the back portion 32 is provided on the skin portion 35 that comes into contact with the back and shoulders, and only the skin portion 35 that is in contact with the human body when seated is heated so that a thermal feeling can be obtained effectively. By arranging the PTC heaters 33 and 34 so as to effectively obtain a feeling of warmth in this way, it is possible to provide heating with low energy and quick start-up.

  In this embodiment, an example in which the PTC heater 33 of the seat portion 31 is provided at one place and the PTC heaters 34 of the back portion 32 is provided at three places is shown, but the arrangement is not limited and the seat portion is important. The arrangement of the PTC heaters 33 and 34 of the back 31 and the back 32 may be different and may be effectively provided directly under the skin portion 35.

(Embodiment 3)
FIG. 4 is a partial cross-sectional view of the air conditioning seat device according to Embodiment 3 of the present invention. In addition, the thing of the same code | symbol as Embodiment 1 has the same structure, and abbreviate | omits description.

  The third embodiment is different from the first embodiment in that P is provided on the seat portion 31 and the back portion 32 of the seat with different arrangements of the jet ports 26a as shown in FIG. That is, the density of the outlets 26a is increased at the center of the back portion 32, and the PTC heaters 34 are provided on both sides thereof.

  In the configuration described above, a large amount of dry air is ejected from the spout 26a provided at the center of the back portion 32, passes through the clothing, reaches the back, and promptly reaches the upper back along the depression on the human body surface along the spine. Because it is supplied, a cool feeling can be quickly obtained over a wide area of the back. For this reason, even if there is little air volume of the dry air supplied, since a cool feeling of a human body is felt effectively, an apparatus can be reduced in size. Furthermore, since a cool feeling can be obtained with a small amount of air, the amount of air can be reduced and the operating noise of the apparatus can be reduced.

  In the present embodiment, the configuration in which many jet outlets 26a are provided in the central portion of the back portion 31 is shown. However, this configuration is not necessarily limited, and the main point is that each of the jet ports 26a of the back portion 31 and the seat portion 32 is provided. It is only necessary that the arrangement is different and effective.

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 used car seats, heating appliances, and heating appliances.
