Title:
FILTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/073723
Kind Code:
A1
Abstract:
This filter device (1, 1a, 1b, 12) collects foreign material (80) contained in the air sucked into an air suction port (5, 60, 62, 70) of an air conditioning device (2, 41) or the air flowing into a heat exchanger (13, 51, 53) from the air suction port (5, 60, 62, 70). A filter member (20) is formed into a sheet and is disposed such that air flows therethrough. One side of the filter member (20) in a longitudinal direction is wound around a first shaft (21). A second shaft (22) supports the opposite side of the filter member (20) to the first shaft (21) across a part (20a) of the filter member (20) through which air flows. The filter member (20) is configured such that when the part (20a) through which air flows moves toward the second shaft (22), a part of the filter member (20) that has been wound around the first shaft (21) is drawn toward the second shaft (22) and serves as a new part (20a) through which air flows.
