Abstract

A flow-straightening device at a coupling portion between: an air supply chamber adjacent to a coating chamber and supplying air to the coating chamber via a filter provided at a boundary wall between the air supply chamber and the coating chamber; and an air supply duct supplying air to the air supply chamber in a direction along the boundary wall. When a direction parallel to the boundary wall and perpendicular to the air supply chamber width direction is an air supply chamber depth direction; and a direction perpendicular to the boundary wall is an air supply chamber thickness direction, the device includes a plurality of fins arranged in the air supply chamber width direction and the air supply chamber depth direction and juxtaposed to each other to be spaced apart from each other in the chamber thickness direction.

Dependent claims

A flow-straightening device provided at a coupling portion between:

an air supply chamber adjacent to a coating chamber and supplying air to the coating chamber via a filter provided at a boundary wall between the air supply chamber and the coating chamber;
and an air supply duct supplying air to the air supply chamber in a direction along the boundary wall, the flow-straightening device comprising
a plurality of fins extending in an air supply chamber width direction and an air supply chamber depth direction and arranged to be spaced apart from each other in an air supply chamber thickness direction, wherein a depth direction of the air supply chamber as seen from an air supply direction from the air supply duct is the air supply chamber depth direction;
a direction parallel to the boundary wall and perpendicular to the air supply chamber depth direction is the air supply chamber width direction;
and a direction perpendicular to the boundary wall is the air supply chamber thickness direction, wherein
the plurality of fins include a first fin disposed substantially parallel to the boundary wall, and a plurality of second fins positioned nearer to the boundary wall than the first fin is, the plurality of second fins increasingly tilting toward the boundary wall with increases in distance in the air supply chamber depth direction, and
in the plurality of second fins, the second fin nearer to the boundary wall has a greater tilt angle relative to a plane parallel to the boundary wall.
