  During heating, air flows in a direction opposite to the direction indicated by the arrows in FIGS. 4 (a) and 4 (b). That is, the air blown out from the first ventilation port 2 a provided in the side surface portion 114 of the seat 11 is provided in the seating portion 111, the backrest portion 112, and the head support portion 113 of the seat 11 via the occupant P. It is sucked from the second ventilation port 2b. That is, an air flow is generated around the occupant P in the process in which the air blown from the first ventilation port 2a is sucked from the second ventilation port 2b.

Next, the operation in the first embodiment will be described.
First, the effect | action of the air-conditioning structure part 12 is demonstrated.
As shown in FIG. 3A, when the first valve 125a is at the position A, the air flowing in from the second ventilation port 2b flows into the second path R2 as shown by the arrow. The air in the second path R <b> 2 is sucked into the sirocco fan 126, and then flows toward the fifth path R <b> 5, that is, the heat exchanger 124. The air flowing into the heat exchanger 124 in the fifth path R5 is heated by hot water (not shown). The heated air passes through the fifth path R5 on the upper side (upper side in FIG. 3A) and is sucked into the sirocco fan 126. The air sucked into the sirocco fan 126 is blown out to the side of the sirocco fan 126 (left and right direction in FIG. 3A). As shown in FIG. 3A, when the first valve 125a is at the position A, the air blown to the right from the sirocco fan 126 is blocked by the first valve 125a in the first path R1.

  The air sucked into the sirocco fan 126 is blown out to the left side of the sirocco fan 126 in FIG. 3A and then flows into the third path R3. As shown in FIG. 3A, when the second valve 125b is at the position C, the air that has flowed into the third path R3 is blown out from the first ventilation port 2a as indicated by an arrow. In addition, when the 2nd valve 125b exists in the position C, the air inflowed into 2nd path | route R2 is not blown off from the 1st ventilation port 2a via 4th path | route R4.

  FIG. 3B shows an air flow in the air conditioning structure 12 during cooling. As described above, control is performed so that the first valve 125a is at position B and the second valve 125b is at position D during cooling. Air flows in the direction indicated by the arrow in FIG. That is, air flows in from the first ventilation port 2a and blows out from the second ventilation port 2b.

Next, the action of the air flow (airflow) will be described.
When air is blown directly to the occupant P, the perceived temperature decreases. Therefore, for example, at the time of cooling, the cool feeling felt by the occupant P is improved by blowing the cool air (cooled air) directly to the occupant P. On the other hand, when warm air (heated air) is blown directly to the occupant P during heating, the sensible temperature decreases, and thus the heating efficiency decreases. That is, compared with the case where the warm air is not blown out directly (when the warm air is blown out around the occupant P), in the case where the warm air is blown out directly to the occupant P, in order to make the occupant P feel a certain warmth, A high warm air temperature is required.

Further, when the air flows so as to wrap around the occupant P, it becomes personal air conditioning, that is, it is possible to air-condition the surroundings of each occupant, so that the air conditioning efficiency is improved as compared with the case where the entire vehicle interior is air-conditioned.
Therefore, when air is directly blown out to the occupant P (when air is blown out from the second ventilation opening 2b) and when air is blown around the occupant P (air is blown out from the first ventilation opening 2a). It is desirable to be able to switch between cooling and heating.

  The vehicle air conditioner 1 includes a first ventilation port 2a through which air can enter and exit, a second ventilation port 2b through which air can enter and exit, and an air flow path that connects the first ventilation port 2a and the second ventilation port 2b. A first valve 125a and a first valve 125a that are connected to the pipe 121 and that can control the flow direction of air in the air flow path. Two valves 125b are provided. The first ventilation port 2 a is provided on the side surface portion 114 of the seat 11, and the second ventilation port 2 b is provided on the seating portion 111 of the seat 11, the backrest portion 112, and the occupant side of the head support portion 113.

  Then, by switching the air flow direction using the first valve 125a and the second valve 125b, the air is blown directly from the first vent 2a to the occupant P, and the air is circulated around the occupant P from the second vent 2b. It is possible to switch between blowing out. That is, the airflow to the passenger P can be adjusted, and the air conditioning efficiency is improved.

  The first ventilation opening 2 a is provided on the side portion of the seat 11. The air is blown out from the first vent 2a toward the occupant P. Therefore, the air reaches the occupant P via the periphery of the occupant P while the air blown out from the first vent 2a is sucked from the second vent 2b. Therefore, the air flow surrounding the passenger P can be formed, and the air conditioning efficiency is good.

  The pipe 121, the heat exchanger 124, the first valve 125 a and the second valve 125 b (air conditioning structure unit 12) are all provided inside the seat 11. Therefore, the vehicle air conditioner 1 can be formed compactly, and the interior space is not narrowed.

  The second ventilation opening 2 b is provided in the head support portion 113. Therefore, when air is blown out from the second ventilation opening 2b during cooling, the air can be blown directly to the head of the occupant P, and the occupant P can feel cool. When the head is cooled, the sensible temperature tends to decrease. That is, the cooling efficiency is increased.

  If the amount of air blown out (sucked) from the first vent 2a is not equal to the amount of air sucked (blowed out) from the second vent 2b, it will not circulate around the occupant P and will not circulate Air will flow in a remote space. However, in the first embodiment, the amount of air blown out (sucked) from the first vent 2a is equal to the amount of air sucked (blowed out) from the second vent 2b. Therefore, the air heated (cooled) by the heat exchanger 124 is difficult to escape from the space around the passenger P. Therefore, it is easy to circulate the airflow around the passenger P.

The above-described embodiment has the following operational effects.
(1) The vehicle air conditioner 1 communicates the first ventilation port 2a through which air can enter and exit, the second ventilation port 2b through which air can enter and exit, the first ventilation port 2a, and the second ventilation port 2b.

The first ventilation port 2 a is provided in the side surface portion 114 of the seat 11, and the second ventilation port 2 b is provided in the seating portion 111, the backrest portion 112, and the head support portion 113 of the seat 11.
When the air flow direction is switched by the first valve 125a and the second valve 125b, the air is blown directly from the first vent 2a to the occupant P, and the air is blown from the second vent 2b around the occupant P. And can be switched. Therefore, the airflow with respect to the passenger P can be adjusted.

(2) The first ventilation opening 2 a is provided on the side portion of the seat 11. Since air can be blown out around the occupant P from the first ventilation opening 2a, an air flow surrounding the occupant P can be easily formed by sucking air from the second ventilation opening 2b.

(3) The pipe 121, the heat exchanger 124, the first valve 125 a, and the second valve 125 b (air conditioning structure unit 12) are all provided inside the seat 11. Therefore, the vehicle air conditioner 1 can be formed compactly.

(4) The second ventilation opening 2 b is provided in the head support portion 113. Therefore, when air is blown out from the second vent 2b during cooling, the air can be blown directly to the head of the passenger P, and the cooling efficiency is increased.

(5) The amount of air blown out (sucked) from the first vent 2a is equal to the amount of air sucked (blowed out) from the second vent 2b. Therefore, the air heated (cooled) by the heat exchanger is difficult to escape to the outside of the vehicle. Therefore, it is easy to circulate the airflow around the passenger.
