Description
以下、本発明の実施の形態1について、図面を参照しながら説明する。なお、この実施の形態1によってこの発明が限定されるものではない。
の騒音レベルを示している。また特性曲線eは従来技術による吸入マフラでの冷媒圧縮機の騒音レベルを示している。このグラフからも明らかなように、本発明の吸入マフラ137によって、密閉容器101が持つ高域の共振周波数付近の周波数f(約2000Hzや約2500Hz)における騒音レベルが大幅に低減されていることが分かる。

Claims (5)
- 密閉容器を有する冷媒圧縮機であり、前記密閉容器は、潤滑油を貯溜するとともに圧縮要素を収容し、前記圧縮要素は、冷媒ガスが圧縮される圧縮室と、前記圧縮室に連通するとともに消音空間を形成する吸入マフラを備えた構成とし、さらに、前記吸入マフラは、一端が前記密閉容器内に開口し、他端が前記消音空間に開口する尾管と、一端が前記圧縮室内に開口し、他端が前記消音空間に開口するとともに、前記尾管の前記消音空間に対する開口方向と直交する前記消音空間に対する開口方向を有する連通管を備え、前記尾管の前記消音空間に対する開口方向の位置および前記連通管の前記消音空間に対する開口方向の位置を、それぞれ前記消音空間の中央とした冷媒圧縮機。
- 前記尾管の前記消音空間に対する開口部が、前記連通管の前記消音空間に対する開口部に近接している請求項1に記載の冷媒圧縮機。
- 前記尾管を、鉛直方向に延びる鉛直部と、前記鉛直部に連続してL字型に屈折して他端が前記消音空間に開口するL字型屈折部を備える構成とした請求項1または2に記載の冷媒圧縮機。
- 前記尾管の前記鉛直部の延長線上に、下方に開口したサイドブランチ型共鳴器を設けた請求項3に記載の冷媒圧縮機。
- 前記サイドブランチ型共鳴器は区画壁にて区画され、複数の共鳴周波数を持つ請求項4に記載の冷媒圧縮機。
