Abstract
Description
前記ファンは給風口と送風口を有し、前記送風口には少なくとも2つの中空の送風路が設けられ、そのうち、少なくとも1つの前記送風路内には前記発熱体が取り付けられる。前記発熱体が取り付けられた前記送風路を流れる風は前記発熱体によって加熱され、かつ前記温風循環マットの内部に供給される。前記発熱体が取り付けられていない前記送風路を流れる風は前記温風循環マットの内部に同時に供給され、それによって前記温風循環マットの給風部位の高い温度が低下させる。前記ファンと発熱体の動作は前記制御部によって制御される。
前記マット本体は三次元メッシュ構造を有する給気路層と還気路層を含み、前記給気路層と還気路層の間には前記給気路層と還気路層を分離し、かつ断熱保温の役割を果たす還気分離層が敷設される。前記還気分離層には還気入口が開けられる。
図1〜図4に示すように、本実施例の温風循環マット用送風装置は、温風循環マットの内側又は外側に設けられ、前記温風循環マット内に送風するために用いられ、ファン10、PTC発熱体20、及び制御部30を含み、ここで、
前記ファン10は給風口13と送風口11を有し、前記送風口11には3層の中空の送風路12が設けられ、それぞれは上部送風路121、中間送風路122、及び下部送風路123である。前記中間送風路122内に1つの前記PTC発熱体20が取り付けられる。前記ファン10とPTC発熱体20の動作は前記制御部30によって制御される。
(一)温度の変化とともに入力パワーを自動的に調整する方式。
(二)設定温度に基づいて自動的に起動、停止する方式。
図5、図7〜図9に示すように、本実施例の温風循環マットは、基本構造がマット本体100、及び実施例1の送風装置200を含み、前記送風口11は送風口本体111、及び前記送風口本体111に取り外し可能に接続される第2接続部112を含み、前記送風路12はいずれも前記第2接続部112内に設けられる。前記第2接続部112内において、前記発熱体20が取り付けられた送風路12は前記温風循環マットの内部に連通する。
図12と図13に示すように、本実施例の基本構造は実施例2と同じであり、相違点は以下のとおりである。
図17に示すように、本実施例の基本構造は実施例2と同じであり、相違点は以下のとおりである。
従来技術において、一般的には、温風循環マットの給風端と末端の間の温度差が10℃以下であると、良好な均一加熱効果を達成していると見なされ、5℃以下であると、相当よい均一的な加熱効果と見なされる。
