Abstract
【解決手段】この発明に係る密閉型圧縮機100は、密閉容器1内に、圧縮機構部20と、圧縮機構部20を駆動する電動機10とを有し、電動機10によって回転するクランクシャフト6の偏芯軸6aに嵌合するローリングピストン7を内部に配置するシリンダ16と、シリンダ16の軸方向両端を閉塞するシリンダヘッド4及びフレーム5とによって構成される圧縮室を、ベーンにより高圧室と低圧室に区分して連続的に冷媒の圧縮を行い、HC冷媒を使用する密閉型圧縮機100において、電動機は密閉容器の内周面に嵌合して固定され、電動機の外径を圧縮機構部の外径よりも小さくし、シリンダの内径をD、シリンダの高さHとしたとき、D/Hを0.5以上1.6未満としたことを特徴とする。
【選択図】図3
Description
図1、図2は実施の形態1を示す図で、図1は密閉型圧縮機100を概略的に示す縦断面図、図2は密閉型圧縮機100の要部縦断面図である。
図3は実施の形態2を示す図で、密閉型圧縮機100を概略的に示す縦断面図である。
(1)電動機10の外径Dmを、圧縮機構部20の外径Dcよりも小さくする。
(2)それに伴い、密閉容器1の電動機10を覆う部分1aの内径は、密閉容器1の圧縮機構部20を覆う部分1bの内径よりも小さくなる。
実施の形態2では、圧縮機構部20の外径Dcに対して電動機10の外径Dmを小さくするようにしたが、この実施の形態においては、電動機10の出力の余剰分を減らすために、電動機10のコア2aの幅(軸方向長さ)を、例えばR410Aなどの従来冷媒に対して設定されていた電動機10のコア2aの幅に対して小さくして、電動機10の使用するコア2aの容積を小さくして電動機10の出力を調整する。これに伴って電動機10を覆う密閉容器1の高さも低くする。こうすることにより、密閉容器1の内部容積が縮減されることになる。
