如图1所示，油泵壳体2内限定出内腔21，上油叶片1安装在内腔21内，油泵壳体2
的下端设有进油孔22，进油孔22与内腔21连通，上油叶片1的上部设有进油通道13，进油通道13沿压缩机的曲轴的轴向延伸且相对于压缩机的曲轴的旋转轴线偏心设置，也就是说，进油通道13的中心轴线与压缩机的曲轴旋转轴线不在同一直线上。
进油通道13与内腔21相连通，即进油通道13与进油孔22相连通，上油叶片1上还有设有泄油孔11和排气孔12，排气孔12和泄油孔11分别与进油通道13连通，油泵壳体2上设有泄油连接孔23和排气连接孔24，泄油连接孔23与泄油孔11连通，排气连接孔24与排气孔12相连通。这样，当压缩机运转到一定转速时，可通过进油通道13出油，并通过泄油孔11、泄油连接孔23将多余的泵油泄出，在压缩机启动时通过排气孔12和排气连接孔24进行排气，当压缩机的转速低于该转速时，上油组件100仅通过进油通道13出油，泄油孔11和泄油连接孔23不泄油。从而可保证压缩机内的泵油，避免发生油堵，以保证压缩机的使用性能。
根据本发明实施例的用于冰箱压缩机的上油组件100，通过将排气孔12和泄油孔11设在上油叶片1上，不仅可有效克服变频压缩机在高转速时泵油过多等问题，而且通过将现有技术加工在曲轴上的泄油孔11和排气孔12集成在上油叶片1上，也可以减少曲轴的加工工序，使得压缩机的曲轴结构更加简单、可靠，同时上油叶片1加工简单，而且不需要再投入专用的加工、装配工装，经济效益也更加明显。
在本发明的一些实施例中，上油叶片1的两侧可分别设有凸块14，泄油孔11设在上油叶片1的一侧的凸块14上，排气孔12设在上油叶片1的另一侧的凸块14上。也就是说，泄油孔11和排气孔12分别设在上油叶片1的两侧。泄油孔11连通进油通道13和上油叶片1的外部，排气孔12连通进油通道13和上油叶片1的外部。从而方便排气孔12和泄油孔11的设置，也有利于泄油孔11的泄油以及排气孔12的排气。
具体地，如图1、图4和图5所示，上油叶片1的本体形成为大体片状结构，在上油叶片1的上部的两侧均设有凸块14，凸块14与本体一体成型，进油通道13形成在上油叶片1的上部且沿上油叶片1的轴向延伸，泄油孔11设在上油叶片1的一侧且形成在上油叶片1的一侧的凸块14上，泄油孔11连通进油通道13和油泵壳体2的泄油连接孔23，排气孔12设在上油叶片1的另一侧的凸块14上且连通进油通道13和油泵壳体2的泄油连接孔23。通过两个凸块14从而有利于泄油孔11和排气孔12的设置，而且使得上油叶片1结构简单，不需要对压缩机的曲轴进行二次加工，简化了压缩机的生产工艺。
可选地，上油叶片1的两个凸块14可沿油泵壳体2的径向相对设置，泄油孔11与排气孔12同轴设置。换言之，两个凸块14分别设在上油叶片1的两侧且沿油泵壳体2的内腔21的径向相对设置。如图4和图5所示，从上油叶片1的俯视图可以看出，上油叶片1的本体和两个凸块14的横截面可大体形成为十字形状，上油叶片1安装在油泵壳体2的内腔
21时，从而有利于上油叶片1与内腔21的装配，可加强上油叶片1的结构强度。而且泄油孔11和排气孔12垂直进油通道13且泄油孔11和排气孔12同轴设置，从而可进一步地方便泄油孔11和排气孔12的加工制造。
在本发明的一些实施例中，泄油孔11与泄油连接孔23同轴设置，排气孔12与排气连接孔24同轴设置。结合图2和图5所示，泄油孔11和排气孔12沿水平方向设置，泄油连接孔23与泄油孔11位置相对应且同轴设置，排气连接孔24与排气孔12位置相对应且同轴设置，从而有利于泄油连接孔23与泄油孔11的连通以及排气连接孔24与排气孔12的连通。
有利地，进油通道13可沿竖直方向设置且进油通道13相对压缩机的曲轴的旋转轴线偏心设置，泄油孔11设在上油叶片1的邻近进油通道13的一侧。换言之，进油通道13相对压缩机的曲轴的旋转轴线偏心设置，泄油孔11设在上油叶片1的进油通道13相对压缩机曲轴偏离的一侧。也就是说，进油通道13和泄油孔11相对压缩机的曲轴的旋转轴线偏心设在上油叶片1的一侧，排气孔12设在上油叶片1相对的另一侧。由此，当压缩机的转速升高达到一定转速时，通过泄油孔11可实现泄油，同时可保证排气孔12只进行排气而泵油不会从排气孔12排出。
在本发明的一些示例中，泄油孔11与进油通道13的交接处与曲轴的旋转轴线之间的距离为R，进油孔22的半径为r，R和r可以满足：R＞r。换言之，泄油孔11的中心轴线与进油通道13的交接点与曲轴的旋转轴线之间的距离大于进油孔22的半径大小，从而可保证压缩机的转速达到一定转速时，泵油可从泄油孔11进行泄油，防止发生油堵。
有利地，排气孔12和进油通道13的交接处与曲轴的旋转轴线之间的距离为R1，进油孔22的半径为r，R1和r可以满足：R1＜r。换言之，排气孔12的中心轴线与进油通道13的内周壁的交接点到曲轴的旋转轴线的水平距离小于进油孔22的半径大小，从而可防止进油通道13的泵油从排气孔12排出，以提高压缩机的安全性能。
进一步地，排气孔12的中心轴线与进油通道13的交接处位于曲轴的旋转轴线上，也就是说，进油通道13的内侧壁经过曲轴的旋转轴线，即排气孔12与进油通道13的交接处与曲轴的旋转轴线之间的距离零，从而可保证进油通道13的泵油不会从排气孔12排出，以进一步地保证压缩机的使用性能。
在本发明的一些实施例中，上油叶片1的外周面形成为圆弧面。结合图2和图6所示，油泵壳体2的内腔21的形成为圆柱形，上油叶片1的外周面形成为圆弧面，从而适于与内腔21的内周面配合，进而方便上油叶片1和油泵壳体2的安装装配。可选地，上油叶片1可与油泵壳体2的内腔21过盈配合，以方便上油叶片1与油泵壳体2的安装装配。对于上油叶片1与油泵壳体2之间的装配方式，上油叶片1和油泵壳体2也可以采用其他形式配合连接。例如，上油叶片1和油泵壳体2也可间隙配合或过渡配合，并通过其他结构或者安装
装置进行安装，对此本发明并不作特殊限定，
下面参考附图描述根据本发明实施例的用于冰箱压缩机的上油组件100的一个具体实施例。值得理解的是，下述描述只是示例性说明，而不能理解为对本发明实施例的限制。
结合图1-图6所示，根据本发明实施例的用于冰箱压缩机的上油组件100包括上油叶片1和油泵壳体2。上油叶片1的下部形成为片状结构，上油叶片1的上部限定出进油通道13、泄油孔11和排气孔12，泄油孔11和排气孔12分别与进油通道13连通，进油通道13沿压缩机曲轴的轴向延伸且偏离曲轴的旋转轴线设置。
泄油孔11和排气孔12均与进气通道相垂直且泄油孔11和排气孔12同轴设置，泄油孔11和排气孔12分别设在上油叶片1的相对两侧，泄油孔11设在上油叶片1的进油通道13偏离曲轴旋转轴线的一侧，排气孔12设在上油叶片1的与泄油孔11相对的另一侧上。
如图6所示，进油通道13的横截面可形成为多边形，多边形可以为大体长方形且长方形的远离曲轴的旋转轴向的一边可形成为弧形，从而可以增加进油通道13的尺寸大小，有利于泵油的流通。可以理解的是，本发明实施例的进油通道13也可以为其他形状。
油泵壳体2内限定出内腔21，油泵壳体2的底壁的中心位置处设有与内腔21连通的进油孔22，油泵壳体2的侧壁上设有泄油连接孔23和排气连接孔24，上油叶片1安装在内腔21内，进油通道13与进油孔22连通，泄油连接孔23与泄油孔11连通且同轴设置，排气连接孔24与排气孔12连通且同轴设置，由此，通过泄油孔11和泄油连接孔23可将多余的泵油泄出，通过排气连接孔24和排气孔12可进行排气，从而避免发生油堵，以提高压缩机的使用性能。
有利地，泄油孔11的中心轴线与邻近的进油通道13的侧壁的交接点和曲轴的旋转轴线之间的距离R大于进油孔22的半径r，由此，在压缩机的旋转速度高到一定转速时，从而保证通过泄油孔11可将进行泄油，排气孔12的中心轴线与邻近的进油通道13的侧壁的交接点和曲轴的旋转轴线之间的距离R1小于进油孔22的半径r，从而可防止泵油从排气孔12流出。
进一步地，排气孔12的中心轴线与邻近进油通道13的侧壁的交接点位于曲轴的旋转轴线上，即排气孔12的中心轴线与邻近的进油通道13的侧壁的交接点和曲轴的旋转轴线之间的距离为零，从而可进一步地方盒子泵油从排气孔12流出。
如图6所示，上油叶片1的外周面形成为圆弧面，上油叶片1安装在内腔21内，上油叶片1的外周面适于与内腔21的内周面配合，从而有利于上油叶片1的安装装配。
由此，根据本发明实施例的用于冰箱压缩机的上油组件100，通过将现有技术的曲轴上排气孔12和泄油孔11集成在上油叶片1上，不仅可有效克服变频压缩机在高转速是泵油过多问题，同时无须对曲轴进行多次加工，可减小曲轴的加工工序。
此外，本发明还提出了一种具有上述实施例的用于冰箱压缩机的上油组件100的压缩机。
由于根据本发明上述实施例的用于冰箱压缩机的上油组件100具有上述技术效果，因此，本发明实施例的压缩机也具有上述技术效果，即根据本发明实施例的压缩机，不仅可有效克服变频压缩机在高转速是泵油过多问题，而且可减小压缩机的加工工序。
