Description
これにより、吐出ポートからの冷媒ガスは、膨脹型マフラとして機能するマフラ内に吐出され、マフラ吐出口からの音は減衰される。一方、マフラ内において、音圧値が高くなる位置に吐出口を設けたので、そこでの圧力が下がって、マフラ内の周方向共鳴周波数付近の騒音とそれに起因する振動を小さく抑える大幅な騒音低減効果を得ることができる。
また、この発明の請求項２にあっては、吐出ポートを有する圧縮機構部に、前記吐出ポートを覆うと共に圧縮機構部のシャフト軸心を中心とする円形状に形成された第１マフラと第２マフラを設け、前記第１マフラに、吐出ポートに対してシャフト軸心を挟んで周方向に約１８０度移動した位置にマフラ吐出口を設け、第２マフラに、前記第１マフラのマフラ吐出口から周方向に６０〜９０度移動した位置に第２マフラのマフラ吐出口を設ける。
また、この発明の請求項３にあっては、マフラ内空間の高さを約１６ｍｍ以下とする。
これにより、コンプレッサの密閉ケース内を振動・騒音が伝達し、外部へ放射されにくい６ｋＨｚ以上の高さ方向共鳴周波数にすることが可能となり、主にコンプレッサ騒音の大きな原因である４ｋＨｚ，５ｋＨｚ帯域での高さ方向共鳴周波数を無くして効果的な騒音低減が図れる。
As a result, the refrigerant gas from the discharge port is discharged into the muffler that functions as an inflatable muffler, and the sound from the muffler discharge port is attenuated. On the other hand, since the discharge port is provided in the muffler at a position where the sound pressure value becomes high, the pressure there is lowered, and the noise near the circumferential resonance frequency in the muffler and the vibration caused by the noise are suppressed to a large extent. The effect can be obtained.
Further, in claim 2 of the present invention, the first muffler and the first muffler formed in a circular shape centering on the shaft axis of the compression mechanism portion while covering the discharge port in the compression mechanism portion having the discharge port. Two mufflers are provided, the first muffler is provided with a muffler discharge port at a position moved about 180 degrees in the circumferential direction with respect to the discharge port with respect to the shaft axis, and the second muffler is provided with the muffler discharge of the first muffler. A muffler discharge port of the second muffler is provided at a position moved 60 to 90 degrees in the circumferential direction from the outlet.
Further, in claim 3 of the present invention, the height of the space inside the muffler is set to about 16 mm or less.
As a result, vibration and noise are transmitted inside the sealed case of the compressor, and it is possible to set the resonance frequency in the height direction to 6 kHz or more, which is difficult to be radiated to the outside, mainly in the 4 kHz and 5 kHz bands, which are the major causes of compressor noise. Effective noise reduction can be achieved by eliminating the resonance frequency in the height direction.
なお、この発明にあっては、マフラ吐出口を、円形状に形成されたマフラの外周縁に寄せた位置に設けて、音圧値が高くなる音圧をマフラの外周縁に寄せてそこでの圧力を有効に下げることができるため、マフラ内の周方向共鳴周波数付近の騒音とそれに起因する振動を小さく抑えることが出来るようにしてもよい。 Incidentally, in this inventions, a muffler discharge outlets, provided at a position closer to the outer periphery of the muffler formed in a circular shape, the sound pressure sound pressure value becomes higher closer to the outer periphery of the muffler where Since the pressure of the muffler can be effectively reduced, the noise near the circumferential resonance frequency in the muffler and the vibration caused by the noise may be suppressed to be small.
また、マフラ吐出口を、周方向に長い長円の形状として、マフラ吐出口での圧力をさらに低減させて大幅な騒音低減効果を得ることができるようにしてもよい。 Also, the Ma hula discharge port, and the shape of a long oval in the circumferential direction, and further reduce the pressure in muffler discharge outlets may be able to obtain a significant noise reduction effect.
また、マフラ吐出口を、１つとして、吐出ポートからマフラ吐出口までのマフラ内空間の距離を長くし、これにより、膨張空間が長くなり、騒音低減効果を増すことができるようにしてもよい。 Also, the Ma hula discharge opening, as one, to increase the distance of the muffler space to muffler discharge outlets from the discharge port, thereby, the expansion space is long, so it is possible to increase the noise reduction effect You may.
また、マフラ内空間を高さ方向に仕切り、１つのマフラ内空間の高さを約１６ｍｍ以下として、コンプレッサの密閉ケース内を振動・騒音が伝達し、外部へ放射されにくい６ｋＨｚ以上の高さ方向共鳴周波数として、４ｋＨｚ，５ｋＨｚ付近の音圧が低減するようにしてもよい。 Also, the partition between hula space in the height direction, and the height of one muffler space than about 16 mm, vibration and noise of the compressor of the sealed case transmitted, 6 kHz or more difficult to be radiated to the outside As the resonance frequency in the height direction of, the sound pressure in the vicinity of 4 kHz and 5 kHz may be reduced.
また、マフラ内空間を、仕切部材により高さ方向に仕切ることで構成して、マフラ内を仕切り部材により容易に２段に仕切ることが可能となり、安価なマフラ構成を実現できる。 Also, the Ma hula space, constituted by dividing the height direction by a partition member, the muffler readily becomes possible to partition the two-stage by a partition member, it can realize an inexpensive muffler configuration.
また、マフラを、第１マフラと第２マフラとによる２ピースで構成し、第１マフラの外周縁外面と第２マフラの外周縁内面とを互いに隙間がないように密着結合して、第１，第２マフラを重ね合わせることで２段マフラの組立が簡単にできるようにしてもよい。 Also, the Ma hula, first constructed in muffler and two-piece by the second muffler, tight junctions to an outer peripheral edge outer surface of the first muffler and the outer peripheral edge the inner surface of the second muffler so that no gap with each other, By superimposing the first and second mufflers, the two-stage muffler may be easily assembled.
また、請求項３において、マフラを、少なくとも第１マフラと第２マフラとから構成し、前記第１マフラに、吐出ポートに対してシャフト軸心を挟んで周方向に約１８０度移動した位置に吐出口を設け、第２マフラのマフラ吐出口を、前記第１マフラのマフラ吐出口から周方向に６０〜９０度移動した位置に配置するようにしてもよい。 Also, in請Motomeko 3, the muffler, constructed from at least a first muffler and second muffler, the first muffler, moved approximately 180 degrees in the circumferential direction across the shaft axis with respect to the discharge port A discharge port may be provided at a position, and the muffler discharge port of the second muffler may be arranged at a position moved by 60 to 90 degrees in the circumferential direction from the muffler discharge port of the first muffler.
