According to this, it is possible to secure the clearance between the occupant's head seated in the seat of the vehicle and the vehicle ceiling.
  • the blower is provided at the central portion in the vehicle width direction of the ceiling of the vehicle. According to this, it is possible to send air by a single fan to the plurality of blowout nozzles provided in the B pillars on the left and right in the vehicle width direction. Further, since the range in which the blower blocks the forward visibility of the occupant seated in the second and subsequent rows of the vehicle is reduced, the influence of the blower on the forward visibility of the occupant can be reduced.
  • the blower is provided under the front seat of the vehicle. According to this, it is possible to utilize the dead space under the front seat of the vehicle to secure the vehicle interior space. Further, by providing the blower under the front seat of the vehicle, the distance between the blower nozzle and the blowout nozzle installed on the B-pillar becomes short. Therefore, it is possible to shorten the duct connecting the blowout nozzle and the blower and to reduce the ventilation resistance of the duct. Therefore, this air blowing device can increase the wind speed and the air volume blown out from the blowing nozzle, and can obtain the wind speed and the air volume necessary to reduce the entry of foreign matter such as mosquito into the vehicle compartment.
  • the air blowing device further includes an air intake path for introducing outside air into the vehicle compartment, separately from the front seat door opening and the rear seat door opening.
  • the air blowing device is mounted on a vehicle provided with a front air conditioner unit.
  • the intake path is an outside air intake port of the front air conditioner unit.
  • the air blowing device further includes a control device that controls the operation of the blower and the operation of the front air conditioner unit.
  • the controller operates the front air conditioner unit in the open air mode in conjunction with the operation of the blower. According to this, even if the blower operates and air in the compartment is blown out from the blowout nozzle, the front air conditioning unit operates in the outside air mode and the outside air is introduced into the compartment, so the pressure inside the compartment is negative. Being prevented. Accordingly, it is possible to prevent the occurrence of a circulating flow in which the air blown out from the blowout nozzle is again sucked into the vehicle compartment, so that the entry of foreign matter such as mosquito can be prevented.
  • a filter is provided in the outside air introduction path of the front air conditioner unit, so that foreign matter such as mosquito can be prevented from entering from the front air conditioner unit.
  • the amount of air blown from the outside of the vehicle into the vehicle compartment by the front air conditioning unit is larger than the amount of air blown out of the vehicle from the vehicle interior by the blower. According to this, when the air inside the vehicle compartment is blown out from the blowout nozzle to the outside of the vehicle, it is possible to reliably prevent the vehicle compartment from becoming negative pressure. Therefore, external air can be prevented from entering the vehicle compartment from unintended places, so that the entry of foreign matter such as mosquito can be prevented.
