Abstract:
1. A dust collector, comprising: first and second electrodes including bases each having a grid structure, and a plurality of protrusions protruding in an axial direction of grid holes from the bases, respectively, the first and second electrodes being positioned to face each other, each of the protrusions of the first electrode being inserted into each corresponding one of the grid holes of the second electrode, each of the protrusions of the second electrode being inserted into each corresponding one of the grid holes of the first electrode, dust collecting surfaces to collect dust from an air to be processed being formed on surfaces of the first electrode, wherein each of the protrusions of the first electrode is formed to have a long plate shape extending across a plurality of adjacent grid holes of the grid holes the first electrode, each of the grid holes of the second electrode is formed as an elongate hole extending to conform to each corresponding one of the protrusions of the first electrode, and the protrusions of the second electrode are arranged in a longitudinal direction at end portions on long sides of the grid holes of the second electrode, to conform to the respective grid holes of the first electrode.
