Filter for electric dust collector, electric dust collector, and air conditioner

Abstract

A filter for an electric dust collector includes: a conductive filter frame for surrounding a passage of airflow along a transverse plane that traverses the passage by being supported by a casing of the electric duct collector; and a mesh sheet arranged along the transverse plane, coupled to the filter frame, and having a conductive material at least partially on a surface of the mesh sheet, the conductive material being connected to the filter frame.

Description

technical field [0001] The present invention relates to a filter for an electric dust collector, an electric dust collector, and an air conditioner. Background technique [0002] For example, as disclosed in Japanese Patent No. 4 270234, Japanese Patent No. 4 636990, and Japanese Unexamined Patent Publication No. 2008-190819, a pre-filter is generally incorporated in an air conditioner. The pre-filter removes dust from the airflow. Prevent dust from accumulating in the heat exchanger. [0003] In the prior art, the dust larger than the mesh of the pre-filter is stuck by the mesh of the pre-filter. On the other hand, particles such as dust smaller than the mesh pass through the mesh. If the size of the mesh of the mesh sheet is reduced, the degree of purification of the airflow passing through the mesh sheet increases. However, the ventilation resistance of the airflow increases. Therefore, the cooling and heating capabilities of the air conditioner decrease. [0004] T...

AI Technical Summary

Problems solved by technology

However, in such a pre-filter, dust that is not charged with a counter potential cannot be captured

causing such dust to pass through the pre-filter

Therefore, dust smaller than the mesh cannot be captured as expected
