Abstract

A vehicle air conditioner, including a first duct having a first ventilation opening that is disposed on first side in a width direction of a seat provided in a vehicle, a second duct having a second ventilation opening that is disposed on second side in the width direction of the seat, the second side being opposite side of the first side, and a third duct having a third ventilation opening that is disposed in front of the seat.

First claim

1 . A vehicle air conditioner, comprising:
a first duct having a first ventilation opening that is disposed on first side in a width direction of a seat provided in a vehicle; a second duct having a second ventilation opening that is disposed on second side in the width direction of the seat, the second side being opposite side of the first side; and a third duct having a third ventilation opening that is disposed in front of the seat, wherein the first duct discharges a first airflow, the second duct discharges a second airflow, and the third duct discharges a third airflow, the seat includes a seating section, wherein the first airflow and the second airflow merge with each other above the seating section to remain above the seating section, and wherein a flow rate of the third airflow is switchable between a flow rate that is higher than a flow rate of each of the first airflow and the second airflow and a flow rate that is lower than the flow rate of each of the first airflow and the second airflow.

2 . The vehicle air conditioner according to claim 1 , wherein the seat includes a backrest section attached to the seating section,
wherein the first ventilation opening and the second ventilation opening are each provided on the backrest section, and wherein the third ventilation opening has a width substantially same as a width of the seat.

3 . The vehicle air conditioner according to claim 1 , further comprising a temperature controller provided inside a console box disposed in the vehicle,
wherein the first duct is coupled to the temperature controller, and the first airflow is cooled by the temperature controller, and wherein the second duct is coupled to the temperature controller, and the second airflow is cooled by the temperature controller.

4 . The vehicle air conditioner according to claim 2 , further comprising a temperature controller provided inside a console box disposed in the vehicle,
wherein the first duct is coupled to the temperature controller, and the first airflow is cooled by the temperature controller, and wherein the second duct is coupled to the temperature controller, and the second airflow is cooled by the temperature controller.

5 . The vehicle air conditioner according to claim 1 , wherein a flow rate of the first airflow is within a range from 0.01 meters per second to 6 meters per second, and wherein a flow rate of the second airflow is within a range from 0.01 meters per second to 6 meters per second.

6 . The vehicle air conditioner according to claim 2 , wherein a flow rate of the first airflow is within a range from 0.01 meters per second to 6 meters per second, and wherein a flow rate of the second airflow is within a range from 0.01 meters per second to 6 meters per second.

7 . The vehicle air conditioner according to claim 3 , wherein a flow rate of the first airflow is within a range from 0.01 meters per second to 6 meters per second, and wherein a flow rate of the second airflow is within a range from 0.01 meters per second to 6 meters per second.

8 . The vehicle air conditioner according to claim 4 , wherein a flow rate of the first airflow is within a range from 0.01 meters per second to 6 meters per second, and wherein a flow rate of the second airflow is within a range from 0.01 meters per second to 6 meters per second.
