<p>PURPOSE:To ensure efficient dust collection by forming on the outer wall part of a casing a gradient facing which guides a thin flexible handle installed on the outer wall part of the casing for storing an electrode part in such a manner that the handle is displaced from a position for use which is afloat from an outer wall plate to a storage position along the outer surface of the outer wall plate. CONSTITUTION:The dust collection part of an electric dust collection element arranged in the downstream side of an ionization part in the air flow path of an air harmonization device is equipped with an electrode part E1 and a casing E2 which stores the electrode part internally. The casing E2 consists of a first lateral plate E21 as an outer wall plate located across a gap C with the electrode part E1, and this lateral plate E21 has a handle E3. The handle E3 is of such a construction that slip-out stopper parts E34, E35 are formed at the tip of extension end parts E32, E33 added to both ends of a grasping part E31. The lateral plate E21 has gradient facings E211A, E212A which allow the handle E3 to be guided into a mutually counter-parting direction, along the outer surface of the electrode part E2 which partitions the gap C.</p> |
