Abstract
An air ventilation apparatus for a vehicle using a Coanda effect according to one embodiment of the present invention includes a duct housing having a hollow shape in which an air inlet is formed in one end portion thereof and an air outlet is formed in the other end portion thereof, a cover member having one end portion coupled to surround the other end portion of the duct housing and having the other end portion which is coupled to the board and in which a communication hole is formed to communicate with the discharge port, and an air guide member which is disposed inside the cover member, is hinge-coupled to the duct housing so as to be vertically rotatable, and has a through-hole through which the air outlet communicates with the communication hole.
Claims19
An air ventilation apparatus for a vehicle using a Coanda effect that is mounted inside a board in a vehicle to discharge air into the vehicle through a discharge port formed in the board, the air ventilation apparatus comprising:
- a duct housing having a hollow shape in which an air inlet is formed in one end portion thereof and an air outlet is formed in the other end portion thereof;
- a cover member having one end portion coupled to surround the other end portion of the duct housing and having the other end portion which is coupled to the board and in which a communication hole is formed to communicate with the discharge port;
- and
- an air guide member which is disposed inside the cover member, is hinge-coupled to the duct housing so as to be vertically rotatable, and has a through-hole through which the air outlet communicates with the communication hole,
- wherein, when an inner circumferential surface of the air guide member, an inner circumferential surface of the communication hole, and an inner circumferential surface of the discharge port form a continuous curved surface due to rotation of the air guide member, air supplied from the air inlet is discharged into the vehicle through the discharge port by turning in a direction in which the continuous curved surface is formed.

- wherein an inner circumferential surface of the air guide member, an inner circumferential surface of the communication hole, and an inner circumferential surface of the discharge port form a continuous curved surface so that air supplied from the air inlet is discharged into the vehicle through the discharge port by turning in a direction in which the continuous curved surface is formed, and
- the air guide member is rotated to block a curved flow in which the air supplied from the air inlet moves along an inner circumferential surface of the cover member and the inner circumferential surface of the communication hole.
