Ion generating apparatus and air purifying apparatus

摘要

A housing having a suction port and a discharge port, an impeller 21 and a casing 22 that houses the impeller 21, an air blower 2 housed in the housing, a filter that lets through the air suctioned from the suction port by the air blower 2, and two ion generating sections that generate positive and negative ions are provided. The ion generating section is arranged on a circular-arc guide wall 2a in the casing 22. The positive and negative ions generated by the ion generating section are efficiently included in the air passing through as laminar flow along the circular-arc guide wall 22a.

1. An ion generating apparatus, comprising:
a plurality of ion generators that generate ions; a CPU which is to be a center of a control system; a plurality of output interface devices which are connected to the CPU in parallel and output a driving signal to the plurality of ion generators; and a driving circuit that repeatedly drives the plurality of ion generators in turns in different phases at a duty of 50% or less to prevent the plurality of ion generators from interfering with each other, wherein a ratio of ion concentration obtained when the plurality of ion generators are alternately turned on and off at the duty is high compared to a case where one ion generator among the plurality of ion generators is constantly turned on.
