Claims (3)
- 商用電源からの交流電圧を整流する整流手段と、前記整流手段の出力側に接続される力率改善手段と、前記力率改善手段に内包される第1のスイッチング素子と、前記力率改善手段の出力側に接続される平滑手段と、前記平滑手段に接続されるインバータと、前記インバータに内包される複数からなる第2のスイッチング素子群と、前記インバータに接続されかつアルミニウム若しくは銅またはこれらと略同等以上の電気伝導率を有する低透磁率材料からなる被加熱物を誘導加熱する加熱コイルと、前記インバータの出力の大きさを検出する検知手段と、前記検知手段からの信号を入力しかつ前記インバータの制御を行う制御手段とを備え、前記インバータは前記第2のスイッチング素子群のオン/オフによって高周波電流を前記加熱コイルに供給して前記被加熱物を誘導加熱し、前記力率改善手段は前記第1のスイッチング素子のオン/オフによって力率を改善するとともに、前記制御手段は検知手段出力に基づいた被加熱物の材質判定時において力率改善手段を停止すべく制御する誘導加熱装置。
- 制御手段は、小物加熱状態または被加熱物がない場合において力率改善手段を停止すべく制御する請求項1に記載の誘導加熱装置。
- 制御手段は、商用電源半周期内での検知手段信号読み込みタイミングを力率改善手段の動作時に対して力率改善手段の停止時には遅くする請求項1または2に記載の誘導加熱装置。
