Abstract
A ventilation duct includes an intake port through which fluid is sucked in a different direction from an up-down direction; a discharge port that is located above the intake port; a connecting portion that connects the intake port and the discharge port, and a duct inner surface that is an inner surface of the connecting portion, the duct inner surface being provided such that a fluid channel is provided inside the duct inner surface. A wall portion is provided to linearly extend upward from a lower surface of the duct inner surface and to extend in a right-left direction when seen from an upstream side in a flow direction of the fluid flowing through the fluid channel.
Claims7
A ventilation duct comprising:
- an intake port through which fluid is sucked in from a front side of a vehicle;
- a discharge port that is located above the intake port;
- a connecting portion that connects the intake port and the discharge port;
- and
- a duct inner surface that is an inner surface of the connecting portion, the duct inner surface being provided such that a fluid channel is provided inside the duct inner surface,
- wherein a wall portion is provided only on a lower surface of the duct inner surface to linearly extend upward from the lower surface of the duct inner surface and to extend in a right-left direction when seen from an upstream side in a flow direction of the fluid flowing through the fluid channel,
- wherein a bent portion is provided in an upper surface of the connecting portion, and a downstream portion of the bent portion is bent upward with respect to an upstream portion of the bent portion,
- wherein the wall portion is provided on the duct inner surface at a position that faces the bent portion, and the wall portion is provided at a position that faces the intake port,
- wherein a portion of the lower surface of the duct inner surface, provided between the intake port and the wall portion, is flat,
- wherein the intake port and the wall portion are provided on substantially a same plane extending in a vehicle front-rear direction, and
- wherein a connecting wall portion is provided to extend in a downstream direction from an upper end of the wall portion to the lower surface of the duct inner surface, and the connecting wall portion extends such that a downstream end of the connecting wall portion is located above an upstream end of the connecting wall portion.
