    • A sealed compressor for use in a refrigerator includes a sealed housing having an interior communicated to the outside of the sealed housing through a discharge tube, a compressor element accommodated within the sealed housing, an electric element accommodated within the sealed housing for driving the compressor element, and a coupling tube fluid-connecting the compressor element and the discharge tube within the sealed housing. To avoid a resonant motion of the coupling tube which would otherwise generate obnoxious noise, an inverter controller is employed to allow the electric element to be operated at one of a plurality of frequencies other than the resonance frequency of the coupling tube.
    • 一种用于冰箱的密封压缩机包括:密封壳体,其具有通过排放管连接到密封壳体的外部的内部;容纳在密封壳体内的压缩机元件;容纳在密封壳体内的电气元件,用于驱动压缩机元件 以及耦合管,其将压缩机元件和放电管流体连接在密封壳体内。 为了避免否则将产生令人讨厌的噪声的耦合管的共振运动,采用逆变器控制器来允许电子元件以除耦合管的谐振频率之外的多个频率中的一个频率操作。

    • A closed motor-driven compressor includes a closed vessel containing a lubricating oil collected in a bottom portion thereof, a compression section accommodated in the closed vessel, and a motor section accommodated in the closed vessel for driving the compression section. The compression section includes a crankshaft driven by the motor section and having a lower end submerged in the lubricating oil, and a block for rotatably supporting the crankshaft. The block has a cylinder formed therewith and having an open end. The block also has a rib formed therewith, a generally flat shoulder portion formed on one side of the cylinder, and a leg formed below the generally flat shoulder portion. The compression section also includes a cylinder head secured to the rib for covering the open end of the cylinder. An oil guide is formed with the block for guiding to the bottom portion of the closed vessel a lubricating oil that is sucked up from the lower end of the crankshaft, caused to spout out from the upper end of the crankshaft, and collected on the generally flat shoulder portion. The oil guide prevent the oil from dropping on and flowing over a suction muffler disposed below the rib, and also prevents the oil from dropping directly on the bottom portion of the closed vessel.
    • 封闭的电动压缩机包括容纳在其底部中的润滑油的密闭容器,容纳在密闭容器中的压缩部分和容纳在密闭容器中用于驱动压缩部分的电动机部分。 压缩部包括由电动机部驱动并具有浸没在润滑油中的下端的曲轴和用于可旋转地支撑曲轴的块。 该块具有由其形成并具有开口端的圆柱体。 该块还具有形成在其上的肋,形成在圆筒的一侧上的大致平坦的肩部,以及形成在大致平坦的肩部下方的腿部。 压缩部分还包括固定到肋的气缸盖,用于覆盖气缸的开口端。 导油器形成有用于引导到密闭容器的底部的块,该润滑油从曲轴的下端被吸入,从曲轴的上端喷出并在一般地收集 平肩部。 油引导件防止油落在布置在肋下的吸入消声器上并流过,并且还防止油直接落在密闭容器的底部上。
