Abstract
压缩机具有密闭容器,和装在其内上侧的电动机,和下侧的用上述电动机驱动的旋转压缩元件。该旋转压缩元件包括中间隔板,及在其上下形成的第1缸筒以及第2缸筒,在各个缸体内相互错位180°的第1滚轮和第2滚轮,和将压缩冷媒引入的冷媒通路,和能使从第2缸筒排出的压缩冷媒再返回将上述电动机和上述旋转压缩元件分离开的空间内的旁通管,以及用以将上述空间内的压缩冷媒导向设在上述密闭容器上部的排出管内的切口。
Description
本发明涉及使具有二个缸筒的压缩机冷媒脉动变小、能降低振动和噪音的压缩机。
在具有二个缸筒的压缩机的先有技术中,例如有实公平3-30629号公报所记载的那种压缩机。
该公报所记载的是一种能使从各个缸筒排出的冷媒先在排出消声器中汇合后再排往压缩机内空间的压缩机。
该种以往的压缩机存在这样的问题,即,将脉动成分不同的冷媒汇合到排出消音器内后,由于该脉动成分的干涉而激励排出消音器以及密闭容器振动。
本发明的目的是为了提供一种使冷媒脉动、振动和噪音均显著减少的二缸压缩机。
本发明的压缩机具有密闭容器,和装在该密闭容器内上侧的电动机,和装在该密闭容器内下侧的用上述电动机驱动的旋转压缩元件。该旋转压缩元件具有下列部分:中间隔板,和在该中间隔板上下形成的第1缸筒以及第2缸筒,和在各个缸体内相互错位180°并由上述电动机驱动的第1滚轮和第2滚轮,和分别封住各个缸筒中与中间隔板相反那一侧的开口的上壳体和下壳体,和能使从第2缸筒排出的压缩冷媒流经上述密闭容器的外部再返回将上述电动机和上述旋转压缩元件分离开的空间内的旁通管,和将从第1缸筒排出的压缩冷媒引入上述空间内的冷媒通路,和设在上述密闭容器与上述电动机的压焊部位上、用以将上述空间内的压缩冷媒导向设在上述密闭容器上部的排出管内的切口。
由于本发明具有上述结构,使在第2缸筒内被压缩后通过了旁通管的冷媒和在第1缸筒内被压缩的冷媒汇合于密闭容器内的将电动机和旋转压缩元件分离开的空间内,因而能够抑制不同脉动成分的冷媒之间因压力互相干涉而产生的噪音。
图1是显示本发明一个实施例中的压缩机主要部分的剖视图。图中,101是密闭容器;在该容器内分别在上侧装有电动机102,下侧装有用电动机102驱动的旋转压缩元件103;电动机102由以压焊固定在密闭容器101内壁的定子104和在该定子内侧以旋转轴105为中心旋转的转子106构成。
在定子104的外周与密闭容器101内壁之间沿着旋转轴105的轴方向设有切口107。该切口107构成压缩冷媒的通路。301是定子104的绕线,302是转子106的端环。
旋转压缩元件103由以下部分组成:中间隔板108;和安装在该隔板上下的第1缸筒109和第2缸筒110;和在转轴105上错位180°设置的偏心部分111、112;和利用这些偏心部分在各缸体109、110内转动的第1滚轮113和第2滚轮114;和在第1及第2缸体上分别安装的第1壳体115(上部壳体)及第2壳体116(下部壳体)。在第1缸体和第2缸体内形成了冷媒的压缩空间。
303是向第1缸体供应气体冷媒的吸入口,304是向第2缸体供应气体冷媒的吸入口。
117、118是分别安装在第1框体和第2框体上的排出消音器,用以降低从第1缸体和第2缸体排出的压缩冷媒的排放音。
第1及第2壳体115、116由对转子106的转轴105作轴支承的轴承119、120,和封住第1及第2缸体109、110开口的法兰盘121、122组成。
129是连接通路,该连接通路与第2框体116的排出消音器118内连通,构成从第1缸体109经排出孔(图未示出)向消音器118内排出的压缩冷媒的通路。
130是设置在密闭容器101外部的旁通管。该旁通管一端与连接通路129相通,另一端对着定子104的切口107开口,与空间127、也就是与将密闭容器内的电动机106和旋转压缩元件103分隔的空间305相通。
134是安装在密闭容器101的上壁上的排出管。
135是有底状铜管,在其底上装有探测线圈,利用该探测线圈检测与转子106同时旋转的永磁铁136的磁束,将转子的转子位置变为输出信号,再根据该信号来控制向压缩机(电机102)供应的电力。该铜管在装入引线和探测线圈之后用环氧树脂封死。
在具有上述结构的压缩机中,经吸入口303、304吸入的气体冷媒被第1缸筒109及第2缸筒110和第1滚轮113及第2滚轮114压缩后开启各个排出孔的排出阀,被排进消音器117、118内。
进入排出消音器117内的压缩冷媒经排出消音器117的开口被排入空间305,进入排出消音器118内的压缩冷媒先后通过排出消音器118、连接通路129、旁通管130后被排入空间305。在空间305内混合的压缩泠媒在通过切口107后从排出管134排出。
由于形成了上述的压缩冷媒通路,因此,可以使排出冷媒的压力脉动成分先在各个消音器中得到衰减,而且,由于从第2缸筒110排出的压缩冷媒更进一步通过连接通路129、旁通管130而使压力脉动更进一步得到衰减,而且,由于从第2缸筒110排出的压缩冷媒更过一步通过连接通路129、旁通管130而使压力脉动更进一步得到衰减,所以,当其与来自缸筒109的压缩冷媒在空间305中汇合时,相互间的干涉作用使会受到抑制。
由于本发明具有上述结构,因此能够抑制在第2缸筒内受到压缩后通过旁通管的冷媒与在第1缸筒内受到压缩的冷媒汇合于密闭闭容器内的分隔电机和旋转压缩元件的空间时因不同脉动成分的冷媒间压力的相互涉及而产生的噪音。
