Description

  The present invention provides, for example, an automotive chair or an office chair, a sheet heating element that quickly provides a comfortable state to the human body even when the cool air environment is uncomfortable and does not impair the design. The present invention relates to a temperature control seat device that prevents lifting and the like due to the mounting of the seat and improves the feeling of use.

  2. Description of the Related Art Conventionally, an electric heating apparatus as a temperature control seat device of this type includes a planar heating element having a self-temperature control function, that is, a PTC heater, as one of the planar heating elements particularly used for a vehicle seat heater or the like. Yes.

  As shown in FIG. 5, the PTC heater applies electrodes 2a and 2b by applying a conductive material mixed with metal powder such as silver or copper on a base material 1 made of a polyester film or the like. Reference numeral 3 denotes a resistor, which is applied so as to cover all of the electrodes 2a and 2b or to overlap a part of the electrodes 2a and 2b in order to be electrically connected to the electrodes 2a and 2b. The resistor 3 is composed of a material mainly composed of a carbon material in order to ensure conductivity. In addition, a binder resin for binding the carbon materials together, and a resin for adding a self-temperature control function are mainly used. It is blended. In some cases, a binder resin and a resin to which a self-temperature control function is added are combined as one kind of resin. Lead wires 4a and 4b for supplying electricity are connected to the tips of the electrodes 2a and 2b. By connecting a power source 5 between the lead wires 4a and 4b, a current flows through the electrodes 2a and 2b. Thus, the resistor 3 generates heat.

  The self-temperature control function of the resistor 3 means that the temperature rises due to the heat generated by the resistor 3 when energized. However, when the resistor 3 reaches a certain predetermined temperature, the resistance value of the resistor 3 rapidly increases and the current decreases. Therefore, the amount of heat generated by the resistor 32 becomes extremely small, and the temperature rise is suppressed. That is, the resistor 3 itself controls its own temperature without using another temperature controller.

Further, as shown in FIG. 6, the resistor 6 is formed into a film shape, electrodes 7 made of copper foil or copper wire are attached to both sides, and a film sheet 8 made of polyester resin or the like is attached to both sides of the resistor 6. A laminated type is disclosed (for example, see Patent Document 1).
JP 2002-270343 A

  However, what can be said in common to these PTC heaters is that, in order to protect the electrodes 2a, 2b and the resistors 3, 6 with respect to the seats to be incorporated and to have insulation, as described above, As the exterior material, a base film 1 made of a polyester film or the like, or a resin film made of a film sheet 8 made of a polyester resin or the like, that is, a non-breathable electrically insulating substrate must be used. Therefore, when the PTC heater using this non-breathable electrically insulating substrate is used for a seat, there is no breathability. Therefore, when used for a long period of time, there is a problem that a sweaty sensation is generated.

  In addition, when the PTC heater is incorporated in the seat, if the fixing is insufficient, the PTC heater may be lifted or broken, thereby deteriorating the appearance, or the electrodes 2a and 2b of the PTC heater and the resistors 3 and 5 There was a concern that the performance would deteriorate due to cracks.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and has an object to improve the feeling of use in a temperature-adjustable seat device by preventing a lift or the like due to the mounting of a planar heating element.

  In order to solve the above problems, an air-conditioning temperature control seat device according to the present invention includes a seat support member, a flexible pad disposed so as to cover the support member, a seat cover surrounding the pad, A planar heating element comprising a PTC heater having a self-temperature adjusting function, wherein an electrode and a heating element material are disposed on a non-breathable electrically insulating substrate located between the pad and the seat cover so as to be in close contact with the pad; The sheet heating element is bonded and fixed by an adhesive means such as a double-sided tape, and a through hole is provided at an appropriate position of the sheet heating element.

  With the above-described configuration, the pad and the non-breathable sheet heating element are bonded with a double-sided tape or the like so as to be in close contact with the pad, and the pad and the sheet heating element are disposed in close contact with each other. However, it becomes difficult for wrinkles and sagging to occur along the pad, and the pad and the seat cover are easily adhered to each other, and heat conduction from the planar heating element to the seat cover is more effectively performed directly, The sheet heating element does not lift up, and the number of components can be greatly reduced.

  In addition, a non-breathable planar heating element is provided so as to be in close contact with the pad, so that even if a load such as sitting is applied, the pad is entirely loaded by the planar heating element and deformed. The amount is also reduced.

  Furthermore, since a through-hole is provided at an appropriate position of the sheet heating element, a method of bonding with a steam from the seat cover by interposing a heat-meltable adhesive material between any of the seat cover, the sheet heating element and the pad Is used, even if it is a non-breathable planar heating element, steam will pass through the through hole of the planar heating element so that the vicinity of the through hole of the planar heating element can be firmly bonded become.

  In the temperature control seat device of the present invention, the pad and the non-breathable sheet heating element are bonded with an adhesive material such as a double-sided tape so that the pad and the sheet heating element are in close contact with each other. As a result, the seat cover surface temperature rises, that is, the heat resistance is excellent, and the appearance of the surface heating element floating on the surface and the wrinkles due to the mounting of the sheet heating element are eliminated. In addition, since a non-breathable planar heating element is disposed so as to be in close contact with the pad, the load resistance and durability can be increased by the synergistic effect of the planar heating element and the pad. Since the through-holes are provided at appropriate positions of the sheet-like heating element, troubles such as initial and aged seat covers, sheet-like heating elements and pad floating can be prevented.

  According to a first aspect of the present invention, there is provided a seat support member, a flexible pad disposed so as to cover the support member, a seat cover surrounding the pad, and a non-breathable position between the pad and the seat cover. A sheet heating element comprising a PTC heater having a self-temperature adjusting function in which an electrode and a heating element material are disposed on the electrically insulating substrate, and the sheet heating element is bonded to the pad so as to be in close contact with the pad. And a through hole is provided at an appropriate position of the planar heating element.

  The pad and the non-breathable sheet heating element are attached to each other with a double-sided tape or the like so that the pad and the sheet heating element are in close contact with each other. This eliminates wrinkles and sagging along the pad and makes it easier for the seat cover to be in close contact with each other, and heat conduction from the planar heating element to the seat cover is performed more effectively and directly. It is excellent, and the surface heating element does not lift up, so there is no need to worry about the appearance of the surface heating element floating on the surface, wrinkles due to the installation of the sheet heating element, and the number of components is greatly reduced. become able to.

  In addition, since the sheet heating element is bonded and fixed with an adhesive means such as a double-sided tape so as to be in close contact with the pad, even if a load such as seating is applied, the pad is loaded with the sheet heating element as a whole. Therefore, the deformation amount is reduced, and the load resistance and durability can be increased by the synergistic effect of the planar heating element and the pad.

  Furthermore, since a through-hole is provided at an appropriate position of the sheet heating element, a method of bonding with a steam from the seat cover by interposing a heat-meltable adhesive material between any of the seat cover, the sheet heating element and the pad Is used, even if it is a non-breathable planar heating element, steam can pass through the through hole of the planar heating element, and the vicinity of the through hole of the planar heating element can be firmly bonded, It is possible to prevent troubles such as initial and aged seat covers, sheet heating elements and pad floating.

  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 It must be controlled by a controller at 70 to 120 ° C., and a temperature controller such as a thermo is required, resulting in a complicated 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.

  Further, since the planar heating element is a PTC heater formed by printing, the thickness is thin and there is no unevenness, so there is no concern about the floating of the planar heating element on the seat cover.

  The second invention has a configuration in which a sheet heating element is adhered and fixed by an adhesive means such as a double-sided tape so as to be in close contact with the seat cover of the first invention, and a through hole is provided at an appropriate position of the sheet heating element. is there.

  The planar heating element is adhered and fixed by an adhesive means such as a double-sided tape so as to be in close contact with the seat cover, and a through hole is provided at an appropriate position of the planar heating element, so that the effect of the first invention can be obtained. Furthermore, the heat conduction from the sheet heating element is directly performed, and the seat cover surface temperature rise, that is, the rapid heat property is excellent, and the sheet heating element can be configured without worrying about the thickness of the sheet heating element and floats on the surface. There is no need to worry about the appearance of the shape and wrinkles due to the mounting of the planar heating element, and the number of components can be greatly reduced.

  The third invention is a combination of the first and second inventions in particular, wherein the sheet heating element is bonded and fixed by bonding means so as to be in close contact with the pad and the seat cover, and the bonding means for closely contacting the sheet heating element is provided. One is used as an immediate adhesive means such as a double-sided tape that adheres when the sheet heating elements are stacked, and the other is not bonded when the sheet heating elements are stacked, and the adhesiveness can be increased by a process such as heating later. The post-adhesion means such as a hot-melt adhesive core is used, and it is configured to adhere by different adhesion methods.

  Then, attach the sheet heating element to either the pad or the seat cover with an immediate adhesive means such as double-sided tape first, and then attach it with a subsequent adhesive means such as a hot-melt adhesive core after aligning the positions. In addition, the sheet heating element is attached in a fixed position between the pad and the seat cover so that positioning is easy.Furthermore, the post-adhesion means is wider than the sheet heating element and the pad and seat cover are faced by the post-adhesion means. It is possible to fix the sheet-like heating element in close contact, and to eliminate worries such as wrinkles due to the installation of the seat cover and the sheet-like heating element.

  The fourth aspect of the invention is an air layer member in which an air flow path is provided in the support members of the first to third aspects of the invention, and an air layer of air from the air flow path is formed above the support member. And a PTC heater is provided so as to cover the air layer member, and an air outflow opening for controlling the outflow of air from the air layer member is provided in the PTC heater.

  And since the non-breathable PTC heater which covers the air layer member and has an air outflow opening for controlling the outflow of air from the air layer is disposed, the air layer member can be formed with a large volume, and the seat The whole can be filled with air from the air flow path. In other words, the air adjusted by the air quality adjusting means etc. is blown to the air layer member, so that 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. It can be ejected from the air outflow opening of a non-breathable planar member provided at a proper position through the outlet of the seat cover, and can be adjusted by the position and shape of the air outflow opening of the PTC heater. 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. 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 ejection position can be regulated by the air outflow opening of the PTC heater. The design can also increase the degree of freedom. In addition, since the PTC heater is configured to cover the air layer member, even if a load such as seating is applied, the PTC heater is applied to the air layer member as a whole, and the deformation amount is reduced. The load resistance and durability can be increased by the synergistic effect of the layer members.

  In the fifth aspect of the invention, in particular, a dehumidification adjusting means for adjusting the humidity of the air blown by the blower is disposed in the air flow path of the fourth aspect of the invention.

  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 the sixth aspect of the invention, the humidity adjusting means of the fifth aspect of the invention is composed 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. Furthermore, since the heating means 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.

  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 a temperature control seat device according to Embodiment 1 of the present invention, and FIG. 2 is a schematic view of a PTC heater used in the temperature control seat device.

  An air flow path 13 of air quality adjusting means 12 for adjusting the air quality of the seat is formed in the vicinity of the support member 11 forming the skeleton of the seat. 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 provided on the hot junction side, a dehumidifying means 18 for condensing water vapor in 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 controls 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.

  The PTC heater 22 is first attached to the air layer member 21 with an immediate bonding means 27 such as a double-sided tape so as to be in close contact, and thereafter, a post-adhesion means having a wider surface than the PTC heater 22 such as a hot melt bonding core. 28, the seat cover 26 including the PTC heater 22 is closely attached and fixed.

  The PTC heater 22 is composed of a pair of electrodes 24 formed by printing and drying a silver paste on a thin electrical insulating substrate 23 such as a polyester film laminated on a polyester nonwoven fabric 23a, and a polymer so as to overlap the electrodes 24. A heating element material 25 in which resistor ink is formed by printing and drying is formed. Then, a thin electrical insulating overcoat material 29 such as a polyester film on which an adhesive resin layer such as an acrylic adhesive having adhesiveness with the electrode 24, the heating element material 25, and the electrical insulating substrate 23 is formed in advance. Are formed by laminating the covering material 30 laminated with the.

  In the above configuration, the seat is heated by supplying air from the blower 18 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 dehumidifying means 22, then guided to the air layer member 21 through the air flow path 13, and further the air outflow opening 22 a of the PTC heater 22 covering the air layer member 21. It is ejected from the ejection port 26a of the seat cover 26 via the.

  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, the PTC heater 22 is attached to the air layer member 21 with the immediate bonding means 27 such as a double-sided tape so as to be in close contact with each other, and then the surface of the PTC heater 22 wider than the PTC heater 22 such as a hot-melt adhesive core. Since the PTC heater 22 including the PTC heater 22 is closely attached and fixed to the seat cover 26 by the bonding means 28, the PTC heater 22 is less likely to cause wrinkles and sagging along the air layer member 21, and the air layer member 21 including the PTC heater 22 The seat cover 26 and the seat cover 26 are integrated, and heat conduction from the PTC heater 22 to the seat cover 26 is more effectively performed directly, so that the surface temperature rise of the seat cover 26, that is, quick heat performance is excellent. Further, the PTC heater 22 is affixed at a fixed position between the air layer member 21 and the seat cover 26 so that the positioning is simplified, and the PTC heater 22 is prevented from being lifted up. And wrinkles due to the mounting of the PTC heater 22 are eliminated, and the number of components can be greatly reduced.

  Further, since the non-breathable PTC heater 22 is disposed so as to be in close contact with the air layer member 21, the air layer member 21 is entirely loaded by the PTC heater 22 even when a load such as seating is applied. Thus, the amount of deformation is reduced, and the load resistance and durability can be increased by the synergistic effect of the PTC heater 22 and the air layer member 21.

  Further, since the air outflow opening 22a is provided at an appropriate position of the PTC heater 22, a heat-meltable adhesive material is interposed between the seat cover 26 and any one of the PTC heater 22 and the air layer member 21 from the seat cover 26. In the case of using a method of bonding with steam, even the non-breathable PTC heater 22 allows steam to pass through the air outlet opening 22a of the PTC heater 22, and the vicinity of the air outlet opening 22a of the PTC heater 22 Can be firmly bonded, and troubles such as initial and aging of the seat cover 26, the PTC heater 22, and the air layer member 21 can be prevented.

  And since the arranged 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, thereby improving safety. The comfort can be improved. For example, when the PTC heater 22 is a linear heater, the heat generating portion is linear, the heat generating area is narrow, the heat generating surface temperature is increased, and when the average surface temperature is set to 40 ° C., the heat generating portion is locally 70 It must be controlled by a controller at ˜120 ° C., and a temperature controller such as a thermo is required, resulting in a complicated 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 to be arranged is the PTC heater 22, the heating part is planar, the heating area is wide, and if the average surface temperature is set to 40 ° C., the heating part should be 45 to 50 ° C. In addition, since it has a self-temperature control function, a temperature controller such as a thermo is not required, 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, since the PTC heater 22 is a PTC heater 22 formed by printing, the thickness thereof is thin and there are no irregularities, so there is no concern about the PTC heater 22 floating on the seat cover 26.

  And since the PTC heater 22 which has the air outflow opening 22a which covers the air layer member 21 and controls the outflow of air from an air layer is arrange | positioned, the air layer member 21 can be formed large in volume, and a seat The whole can be filled with air from the air flow path. That is, the air adjusted by the air quality adjusting means 12 is blown to the air layer member 21, so that the entire seat can be maintained in a state of being filled with conditioned air, and the conditioned air is ejected from any part of the seat. The air outlet opening 22a of the non-breathable PTC heater 22 provided at an appropriate position can be ejected through the jet outlet 26a of the seat cover 26, and the position of the air outlet opening 22a of the PTC heater 22 can be -It can be adjusted by shape, and it will be possible to blow out the conditioned air that is optimal for conditions such as the seating state according to the design and shape of the seat. 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.

(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 the said structure, as shown in FIG. 3, the dehumidification means 31 performs the reproduction | regeneration mode driving | operation which recovers dehumidification 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, and blown out from the spout 26a26a14 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.

  Thus, for example, the room air is dehumidified by using the dehumidifying means 31 made of an adsorbent such as silica gel or zeolite, and blown out from the jet outlet 26a26a of the seat body to vaporize the sweat on the body surface. 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 felt when sitting for a long time even in winter can be prevented. Furthermore, since the heating means 32 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. .

  As described above, according to the temperature control seat device of the present invention, a comfortable state can be quickly provided to the human body even when the cold environment of the outside air is unpleasant, and lifting due to the mounting of the planar heating element is prevented. Since a seating environment with improved usability can be provided, the present invention can be applied to vehicles such as car seats mainly used for vehicles, heating appliances and heating appliances.
