  The main pad 225 supports the weight of the passenger and is made of urethane foam. The main pad 225 has a first area 220A (first area 210A for the seat cushion 210) and a second area 220B (second area 210B for the seat cushion 210), which will be described later. A concave ventilation groove 225a and an introduction hole 225b communicating with the ventilation groove 225a from outside the anti-ventilation groove are provided.

  The laying pad 224 absorbs the seating pressure when the occupant is seated. Like the main pad 225, the laying pad 224 is made of urethane foam, and a plurality of ventilation holes 224a are formed in a region corresponding to the ventilation groove 225a. . As the placing pad 224, a net having a 3D knitted structure and air permeability may be used.

  As shown in FIG. 3, a plurality of suspension grooves 216, 217, 218 are formed on the surface of the seat cushion 210, and similarly, a plurality of suspension grooves 226, 227, 228 are formed on the surface of the seat back 220. Is formed. The suspending grooves 216 to 218 and 226 to 228 are formed by a skin wire 231 provided on the seat cover being pulled inward and fixed to a pad wire 232 provided in the pad portion by a C ring 233. This is a linear groove (sheet design portion).

  And in the surface (predetermined area | region) of the seat cushion 210 and the seat back 220, the area | region which requires seat air conditioning among several area | regions divided by the several hanging grooves 216-218, 226-228 is the 1st area | region. (210A, 220A) are defined, and areas where the need for seat air conditioning is lower than the first areas (210A, 220A) are defined as the second areas (210B, 220B). The relationship between the suspension grooves 216 to 218 and 226 to 228 and the first region (210A, 220A) and the second region (210B, 220B) will be described below.

  The suspension groove 216 in the seat cushion 210 is formed in a linear shape so as to extend substantially in the left-right direction near the center so as to divide the surface of the seat cushion 210 in the front-rear direction. In addition, the suspension grooves 217 and 218 are linearly formed to extend in the front-rear direction on both the left and right sides in the rear region of the seat cushion 210 divided forward and backward by the suspension grooves 216.

  In the seat cushion 210, a region in front of the suspension groove 216 is defined as a first region 210A, and a region surrounded by the suspension grooves 216 to 218 is defined as a second region 210B. The first area 210A and the second area 210B are adjacent to each other. The first region 210A is a region that is mainly touched by the crotch portion when a passenger is seated. The second area 210B is an area that is touched by the occupant's buttocks. In the seat cushion 210, the second area 210B is an area where the weight of the occupant is most likely to be applied, the surface pressure is extremely high, and the air supply by the seat air conditioning is difficult to be performed. This is the first area 210A.

  The suspension groove 226 in the seat back 220 is formed in a linear shape so as to extend substantially in the left-right direction near the center so as to divide the surface of the seat back 220 vertically. In addition, the suspension grooves 227 and 228 are linearly formed so as to extend in the vertical direction on both the left and right sides in the lower region of the seat back 220 divided up and down by the suspension grooves 226.

  In the seat back 220, the area surrounded by the hanging grooves 226, 227, and 228 is a first area 220A and the area above the hanging groove 226 is a second area 220B because of the necessity of seat air conditioning. The first region 220A and the second region 220B are adjacent to each other. The first region 220A is a region mainly touched by the lumbar part when the occupant is seated, and is a region (high adhesion region) with high adhesion when the occupant is seated. The second region 220B is a region where the back and shoulders of the occupant are in contact with each other, and the degree of adhesion when the occupant is seated is low.

  The blower 300 is a blowing means for forcibly blowing the air in the passenger compartment into the introduction hole 225b (first area 210A, 220A, second area 210B, 220B) of the seat 200. A total of two are installed, one for each.

  The blower 300 includes a flat cylindrical centrifugal fan (not shown) whose rotational axis direction is set smaller than the outer diameter direction, a motor (not shown) that rotationally drives the centrifugal fan, and these centrifugal fans. And a scroll-shaped casing 310 that houses the motor and forms a ventilation passage.

  One of the two blowers 300 is disposed below the seat cushion 210, in the vicinity of the boundary between the first region 210A and the second region 210B, that is, in the vicinity of the hanging groove 216. Another blower 300 is disposed on the rear side of the seat back 220, in the vicinity of the boundary between the first region 220A and the second region 220B, that is, in the vicinity of the hanging groove 226.

  The first introduction path 510 and the second introduction path 520 connect the outlet 311 (FIG. 6) from which the blown air of each blower 300 is blown out to the respective introduction holes 225 b of the seat cushion 210 and the seat back 220. It is a passage. Hereinafter, the details of the first introduction path 510 and the second introduction path 520 will be described using the seat back 220 side of the seat cushion 210 and the seat back 220 as a representative, with reference to FIG.

  As shown in FIG. 6, the downstream side of the outlet 311 of the casing 310 is formed to open at two places, and one end side of the first introduction path 510 is connected to one opening, The other end side is connected to the introduction hole 225b of the first region 220A (210A) of the seat back 220 (seat cushion 210). The first introduction path 510 is provided with a heat exchanger 400 that heats or cools the air blown from the blower 300 to produce conditioned air (temperature-controlled air). Therefore, the first introduction path 520 serves as a passage for supplying the conditioned air heated or cooled by the heat exchanger 400 to the first region 220A (210A). Further, an exhaust passage 511 that branches from the first introduction path 510 and opens into the vehicle interior is formed in the first introduction path 510.

  In addition, one end side of the second introduction path 520 is connected to another opening on the downstream side of the air outlet 311 and the other end side is a second region 220B (210B) of the seat back 220 (seat cushion 210). Are connected to the introduction hole 225b. Accordingly, the second introduction path 520 is a passage that supplies the blown air that bypasses the heat exchanger 400 from the blower 300 to the second region 220B (210B).

  The heat exchanger 400 disposed in the first introduction path 510 is a heat exchanger 400 using a thermoelectric conversion element (Peltier module). In the heat exchanger 400, for example, a plurality of P-type thermoelectric conversion elements and N-type thermoelectric conversion elements each having a size of about 1.5 mm square are connected in series by electrode members (for example, several hundred pieces). A heat radiating fin is joined to the member.

  When a voltage is applied to a series circuit formed by a plurality of P-type thermoelectric conversion elements and N-type thermoelectric conversion elements and a direct current is passed in the order of P → N → P (hereinafter referred to as a positive current), An electrode member through which a current flows from the P-type thermoelectric conversion element to the N-type thermoelectric conversion element is the heat radiation electrode portion 402. The heat radiation electrode part 402 is an electrode part that is brought into a high temperature state (heat radiation state) by the Peltier effect. An electrode member through which a current flows from the N-type thermoelectric conversion element to the P-type thermoelectric conversion element is the endothermic electrode portion 401. The endothermic electrode portion 401 is an electrode portion that is brought into a low temperature state (endothermic state) by a positive direction current. The endothermic electrode portion 401 in the heat exchanger 400 is disposed in the first introduction path 510 connected to the introduction hole 225b, and the heat radiation electrode portion 402 is disposed in the exhaust passage 511.

  If the direction of the current flowing through the series circuit of the heat exchanger 400 is the reverse direction (hereinafter referred to as reverse current) with respect to the forward current, the endothermic electrode 401 is in a high temperature state, and the heat dissipating electrode 402 is It is possible to switch so that the heat absorption and heat radiation operation positions are reversed.

  The blower 300 and the heat exchanger 400 are connected to an existing A / C unit (not shown) mounted on the vehicle. The blower 300 starts the motors and rotates the fans to suck the conditioned air in the passenger compartment whose temperature has been adjusted by the A / C unit and forcibly blow it into the pad portions of the seat cushion 210 and the seat back 220. Be able to. In addition, you may make it the air blower 300 attract | suck the conditioned air in a vehicle interior, without connecting the air blower 300 and an A / C unit. Further, the heat exchanger 400 can cool or heat the blown air supplied to the heat exchanger 400 from the upstream side of the first introduction path 510 by applying a voltage.

  Next, the operation of the seat air conditioner 100 based on the above configuration will be described. First, when the vehicle interior is being cooled and the seat air conditioning is activated (cooling mode), the blower 300 and the heat exchanger 400 are activated by a seat air conditioning request command from the A / C unit. In each blower 300, the motor and the centrifugal fan are operated, and the air sucked from the passenger compartment passes through the first introduction path 501 and the second introduction path 502, and the first area 210A and the second area of the seat cushion 210. The air is sent to 210B and to the first area 220A and the second area 220B of the seat back 220. In the heat exchanger 400, a positive current is applied, and the heat absorption action is generated in the heat absorbing electrode unit 401 by this positive current.

  Hereinafter, the seat back 220 side of the seat cushion 210 and the seat back 220 will be described as a representative part. As shown in FIG. 6, the air (cooling air) blown from the blower 300 branches on the downstream side of the outlet 311 and flows through the first introduction path 510 and the second introduction path 520. The blown air flowing through the first introduction path 510 is further cooled by the endothermic action of the heat exchanger 400 (the endothermic electrode portion 401) and reaches the first region 220A (210A) as cooling air. The air flowing through the exhaust passage 511 is heated by the heat radiation action of the heat exchanger 400 (heat radiation electrode portion 402) and is discharged into the vehicle interior. Also, the blown air flowing through the second introduction path 520 reaches the second region 220B (210B) directly from the blower 300.

  When seat air conditioning is activated when the passenger compartment is heated (heating mode), a reverse current is applied to the heat exchanger 400 and a heat dissipation action is generated in the heat absorbing electrode section 401. Therefore, the air (heating air) sucked from the passenger compartment by the blower 300 is further heated in the first introduction path 501 and reaches the first region 220A (210A) as heating air. Also, the blown air flowing through the second introduction path 520 reaches the second region 220B (210B) directly from the blower 300.

  Here, in the prior art, the discharge pipe is branched on the downstream side of the temperature control means and receives all the ventilation resistance of the temperature control means. However, in this embodiment, the ventilation resistance between the blower 300 and the first region 220A (210A) and the second region 220B (210B) is reduced by the amount that the second introduction path 520 does not pass through the heat exchanger 400. Therefore, as shown in FIG. 7 (fan characteristics and ventilation resistance), it is possible to increase the amount of air blown to the first region 220A (210A) and the second region 220B (210B). And the air-conditioning air temperature-controlled to the 1st area | region 220A (210A) in need of sheet | seat air conditioning is supplied, and sufficient sheet | seat air conditioning can be performed. Further, although the temperature is not controlled by the heat exchanger 400, the air having a sufficient air flow rate is supplied to the second region 220B (210B) adjacent to the first region 220A (210A). 210 and the seat back 220 can eliminate the distribution of the temperature sensation over the entire seat back 220 to provide a seat air conditioner 100 that provides a comfortable air conditioned feeling.

  Further, since the first region 220A in the seat back 220 is a region (waist) where the degree of adhesion becomes high when the occupant is seated, effective seat air conditioning can be performed without waste.

  Further, in setting the sections of the first areas 210A and 220A and the second areas 210B and 220B in the sheet 200, since the boundaries are formed using the hanging grooves 216 to 218 and 226 to 228, special sections are formed. It is possible to easily cope with the need for no means.

  Further, since the blower 300 is provided in the vicinity of the boundary between the first regions 210A and 220A and the second regions 210B and 220B, both the first introduction path 510 and the second introduction path 520 can be set short, and the first The introduction path 510 and the second introduction path 520 are easily arranged in the seat 200.

(Second Embodiment)
A second embodiment of the present invention is shown in FIGS. 2nd Embodiment adds the opening / closing door 530 as an opening-closing means to the upstream opening part of the 2nd introduction path 520 with respect to the said 1st Embodiment.

  The opening / closing door 530 is a plate-like door that rotates about a rotation axis, and opens and closes the opening of the second introduction path 520 by an actuator (not shown). The actuator of the opening / closing door 530 is connected to an A / C unit (not shown), and the opening / closing of the opening / closing door 530 is controlled by a control unit of the A / C unit.

  Specifically, as shown in FIG. 9, in the stop mode in which the seat air conditioner 100 is stopped, the cooling mode in which the cooling operation is performed, and the blowing mode in which only the blowing without air conditioning is performed, the opening / closing door 530 is The opening is kept open by the actuator. In the heating mode for heating operation, the open / close door 530 is controlled to close the opening.

  In the stop mode of the seat air conditioner 100, energization to the heat exchanger 400 is stopped, the blower 300 is stopped, and the open / close door 530 is opened.

  In the cooling mode, a forward current is applied to the heat exchanger 400, the blower 300 is operated, and the open / close door 530 is opened. As a result, the cooling operation described in the first embodiment is executed.

  In the air blowing mode, power supply to the heat exchanger 400 is stopped, the air blower 300 is operated, and the open / close door 530 is opened. Thereby, the air temperature control (cooling or heating) by the heat exchanger 400 is not executed, and only the blown air from the blower 300 is supplied to the first regions 210A and 220A and the second regions 210B and 220B. The

  In the heating mode, a reverse current is applied to the heat exchanger 400, the blower 300 is operated, and the open / close door 530 is closed. Thus, the air flowing through the first introduction path 510 is heated by the heat exchanger 400 and reaches the first regions 210A and 220A. However, the supply of air from the second introduction path 520 to the second regions 210B and 220B is stopped. This is because even when the vehicle interior is heated by the A / C unit, if the air sucked from the vehicle interior is blown directly to the seat 200, there is a risk of giving the passenger discomfort (not warm).

  As described above, the open / close door 530 can prevent the low temperature air from being blown to the second regions 210B and 220B in the heating mode, thereby preventing the seated person from damaging the feeling of heating.

  In the heating mode, the temperature of the air sucked by the blower 300 is detected, and the door 530 is closed when the temperature is lower than the predetermined temperature, and the door is opened when the temperature of the air sucked is higher than the predetermined temperature. 530 may be opened.

  Accordingly, the seat air-conditioning apparatus 100 can obtain a sufficient feeling of heating when the temperature of the sucked air is high so that the feeling of heating is not impaired only when the temperature of the sucked air is low.

  The opening / closing door 530 serving as the opening / closing means is not limited to a rotary plate door, and may be a sliding door, a rotary door, or the like.

(Third embodiment)
A third embodiment of the present invention is shown in FIGS. 3rd Embodiment adds the heater 410 as a heat exchanger for a heating in the 2nd introduction path 520 with respect to the said 1st Embodiment.

  The heater 410 is set such that the ventilation resistance is suppressed to be smaller and the resistance to the blown air flowing through the second introduction path 520 is not as much as possible (the ventilation resistance is set to be smaller than a predetermined value). Here, the heater 410 is mainly composed of a nichrome wire (high electric resistance wire). The heater 410 energizes the nichrome wire, thereby generating heat due to electric resistance and heating the blown air.

  In the third embodiment, as shown in FIG. 11, as in the second embodiment, the operation mode of the seat air conditioner 100 includes a stop mode, a cooling mode, a blower mode, and a heating mode. In the stop mode, the cooling mode, and the air blowing mode, the energization of the heater 410 is stopped, and the energization of the heater 410 is performed in the heating mode.

  In the stop mode of the seat air conditioner 100, energization to the heat exchanger 400 is stopped, the blower 300 is stopped, and energization to the heater 410 is stopped.

  In the cooling mode, a forward current is applied to the heat exchanger 400, the blower 300 is activated, and the energization of the heater 410 is stopped. As a result, the cooling operation described in the first embodiment is executed.

  In the air blowing mode, power supply to the heat exchanger 400 is stopped, the air blower 300 is activated, and power supply to the heater 410 is stopped. Thereby, the air temperature control (cooling or heating) by the heat exchanger 400 is not executed, and only the blown air from the blower 300 is supplied to the first regions 210A and 220A and the second regions 210B and 220B. .

  In the heating mode, a reverse current is applied to the heat exchanger 400, and the air flowing through the first introduction path 510 is heated and supplied to the first regions 210A and 220A. In addition, the heater 410 is energized, and the blown air flowing through the second introduction path 520 is heated by the heater 410 and supplied to the second regions 210B and 220B.

  Thereby, in the heating mode, the air blown through the second introduction path 520 can also be heated by the heater 410, so that the heating effect in the second regions 210B and 220B can be enhanced.

  In addition, the heater 410 as a heat exchanger for heating is not limited to one using a nichrome wire (high electric resistance wire), and so as not to become as much resistance as possible to the blown air flowing through the second introduction path 520. Other types of heaters may be used as long as the ventilation resistance is smaller than a predetermined value.
