Plasma sterilizing module and air purifier including for the same

摘要

The present invention relates to a plasma sterilization module which comprises: a housing installed on a flow path through which air is circulated, having first open surface from which the air is supplied, and having a second open surface facing the first surface and from which the air is discharged; a discharge electrode installed in the housing; and an earth electrode installed in the housing and disposed to be spaced apart from the discharge electrode. The discharge electrode comprises a first discharge electrode receiving high voltage applied thereto to generate plasma discharge toward the earth electrode and a second discharge electrode disposed at the further downstream position of the flow path of the air than that of the first discharge electrode and receiving high voltage applied thereto to generate plasma discharge toward the earth electrode. According to the present invention, the plasma sterilization module sterilizes microorganisms in the air through two stages.
