Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 換気扇の設けられる室内の気密度に応じて羽 根を駆動する単相誘導電動機の出力を調整し、騒音を低 くするとともに、エネルギー損失の少ない換気扇の制御 装置を提供することを目的とする。 【構成】 単相誘導電動機の電流に感応して起電力を発 生する電流検知素子8の出力を検知する電流検知回路9 と、単相誘導電動機に電源を投入して所定時間経過後に 電流検知素子8が設定値以上の電流を検知したときに単 相誘導電動機の出力を保持する出力保持手段11と、電 流検知素子8が設定値未満の電流を検知したときに、単 相誘導電動機の出力を上げる出力上昇手段12を設けた 構成とする。 (57) [Abstract] [Purpose] Providing a control device for a ventilation fan that adjusts the output of a single-phase induction motor that drives the blades according to the air density in the room where the ventilation fan is installed to reduce noise and reduces energy loss. The purpose is to do. [Structure] A current detection circuit 9 for detecting an output of a current detection element 8 which generates an electromotive force in response to a current of a single-phase induction motor. An output holding unit 11 that holds the output of the single-phase induction motor when the current detection element 8 detects a current equal to or more than a set value after a lapse of a predetermined time after turning on the power of the single-phase induction motor; Is provided with output increasing means 12 for increasing the output of the single-phase induction motor when a current less than the set value is detected.
