Air-conditioning outlet device
The air-conditioning outlet device includes the housing having a frame shape and having a flow path through which air flows. The housing has an overlapping surface that a fin is overlappable in a state where the flow path is closed, and a clearance recess recessed from the overlapping surface so as not to come into contact with the fin when the fin rotates from the state where the flow path is closed. The clearance recess of the housing and the fin define a blow-in space into which the air is blown from a gap between the housing and the fin. One of the fin and the housing includes a barrier wall that interferes with the air flowing through the blow-in space.
1. An air-conditioning outlet device comprising:
a housing having a frame shape and having a flow path through which air flows; and
a fin which is disposed in the flow path and by which the flow path is openable and closable,
wherein the fin includes a plate-shaped portion and a pair of shaft portions protruding from the plate-shaped portion in opposite directions,
the housing includes a pair of support portions that support the respective shaft portions and that are integrated with each other,
each of the support portions includes a base portion having a support hole that rotatably supports the shaft portion, with respect to the base portion, a stepped portion stepped in a direction toward a center of the housing with an axis direction of the shaft portion as a reference, and a connecting portion that connects the base portion and the stepped portion,
the connecting portion has an overlapping surface that the plate-shaped portion of the fin is overlappable in a state where the flow path is closed, and a clearance recess recessed from the overlapping surface so as not to come into contact with the fin when the fin rotates from the state where the flow path is closed,
in the state where the flow path is closed, the clearance recess of the connecting portion and the plate-shaped portion define a blow-in space into which the air is blown from a gap between the plate-shaped portion and the base portion, and
one of the fin and the housing includes a barrier wall that interferes with the air flowing through the blow-in space.
2. The air-conditioning outlet device according to claim 1 ,
wherein the shaft portion includes a large-diameter portion having an annular end surface that is contactable with an edge of the support hole,
the barrier wall is formed of a bulging portion that bulges from the fin and the large-diameter portion toward a wall surface of the clearance recess, and
the bulging portion has a facing surface facing the wall surface of the clearance recess.
3. The air-conditioning outlet device according to claim 2 ,
wherein a lightening recess is formed on an opposite side of the fin from the bulging portion.
4. The air-conditioning outlet device according to claim 1 ,
wherein the barrier wall is formed of a fin-side lid portion provided on the plate-shaped portion so as to close the blow-in space.
5. The air-conditioning outlet device according to claim 1 ,
wherein the barrier wall is formed of a housing-side lid portion provided on the housing so as to close the blow-in space.
