OIL COLLECTION DEVICE

WIPO Patent Application WO/2023/032509

A1

Provided is an oil collection efficiency improvement means that is based on a novel principle.　According to the present invention, an oil smoke collection device comprises a blower and a filter. The blower suctions air through the filter. The filter: is a member that has a porous part that has a plurality of holes; and is driven so as to rotate around a rotational axis. Cross-sections of the holes taken by cutting the porous part in the circumferential direction as centered on the rotational axis are spaces that include at least a filter rotational direction front edge and a filter rotational direction rear edge, and, when the surface of the filter that is on the blower side is a downstream surface and the surface that is on the air-suctioning side is an upstream surface, the cross-sections of at least a portion of the holes are shaped such that one end of the rotational direction rear edge that is at the upstream surface is on the opposite side in the rotational direction of the filter from another end that is at the downstream surface, making the rotational direction rear edge slanted.
