本申请要求于2021年05月19日提交至中国国家知识产权局、申请号为202110546987.7、发明名称为“压缩机及具有其的空调器”的专利申请的优先权。
技术领域
本申请涉及空调器技术领域，具体而言，涉及一种压缩机及具有其的空调器。
背景技术
目前，家用空调市场搭载回转式压缩机的空调占比最大，而每年压缩机故障中发生曲轴磨损故障的次数最多。曲轴故障的原因主要表现为曲轴滑动部润滑不足，对于单缸旋转式压缩机的曲轴而言，该曲轴由一个长轴、一个短轴以及一个偏心轴组成，因而共需要润滑主轴的三个滑动部。现有技术中曲轴中心具有供润滑油流通的导油通道(也即为曲轴中心孔)，曲轴中心油孔通常配合具有螺旋结构的导油片来实现泵油功能。具有螺旋结构的导油片属于一种离心泵，需要通过曲轴旋转来泵取润滑油。
然而，对于导油片而言其具有相对设置的迎油面和背油面，且导油片的背油面一侧供油的天然不足，当曲轴连通其滑动部的导油孔正好位于靠近导油片的背油面一侧时，曲轴滑动部的润滑效果将受影响，进而影响了曲轴的润滑效果。
申请内容
本申请的主要目的在于提供一种压缩机及具有其的空调器，以解决现有技术中的曲轴的润滑效果不佳的技术问题。
为了实现上述目的，根据本申请的一个方面，提供了一种压缩机，包括：泵体组件和曲轴，曲轴穿设在泵体组件上，曲轴上设置有导油通道，导油通道沿曲轴的延伸方向延伸；导油片，设置在导油通道内，导油片的至少部分抵接在导油通道的内壁上，以通过导油片将导油通道分为迎油区和背油区，其中，曲轴的侧壁上还设置有朝向泵体组件的导油孔，导油孔与迎油区或背油区连通；导油通道的内壁上设置有连接凹槽，连接凹槽的一端与迎油区连通，连接凹槽的另一端与背油区连通，以使迎油区通过连接凹槽与背油区连通。
进一步地，导油通道为圆柱形通道，连接凹槽的至少部分沿导油通道的周向延伸。
进一步地，连接凹槽为螺旋油槽。
进一步地，螺旋油槽的横截面为半圆形、或梯形、或矩形、或三角形。
进一步地，连接凹槽为环形油槽。
进一步地，导油孔的侧壁与连接凹槽的槽底相切。
进一步地，导油孔为多个，多个导油孔沿曲轴的延伸方向间隔设置，连接凹槽为多个，多个连接凹槽与多个导油孔一一对应地设置，各个连接凹槽与相应的导油孔连通。
进一步地，曲轴包括短轴段和长轴段，导油通道贯通短轴段和长轴段，导油片的至少部分位于短轴段内，导油孔包括第一导油孔，第一导油孔设置在短轴段内，连接凹槽包括第一连接凹槽，第一连接凹槽与第一导油孔连通；泵体组件包括：第一法兰，第一法兰套设在短轴段上，第一导油孔朝向短轴段的径向设置。
进一步地，曲轴包括依次连接的短轴段、偏心段和长轴段，导油通道依次贯通短轴段、偏心段和长轴段，导油片位于短轴段和偏心段内，导油孔包括第二导油孔，连接凹槽包括第二连接凹槽，第二导油孔和连接凹槽均设置在偏心段处，第二连接凹槽与第二导油孔连通。
根据本申请的另一方面，提供了一种空调器，空调器包括压缩机，压缩机为上述提供的压缩机。
应用本申请的技术方案，在运行过程中，由于迎油区通过连接凹槽与背油区连接，这样使得迎油区内的润滑油和背油区内的润滑油能够相互流动，从而提高了润滑油在迎油区和背油区的均匀性，这样，导油孔无论与迎油区连通或是与背油区连通均能够使得有润滑油顺利进入导油孔内，以便于使润滑有流经导油孔后对曲轴与导油孔相对设置的泵体组件之间进行润滑，从而提高了对曲轴的润滑效果。因此，通过本实施例提供的技术方案，能够解决现有技术中的曲轴的润滑效果不佳的技术问题。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
如图1至图10所示，根据本申请的实施例一，提供了一种压缩机1，该压缩机1包括泵体组件、曲轴6和导油片11，曲轴6穿设在泵体组件上，曲轴6上设置有导油通道61，导油通道61沿曲轴6的延伸方向延伸。导油片11设置在导油通道61内，导油片11的至少部分抵接在导油通道61的内壁上，以通过导油片11将导油通道61分为迎油区和背油区。具体的，本实施例中的导油片11具有相对设置的迎油面和背油面，其中迎油面与导油通道61的内壁围成迎油区，背油面与导油通道61的内壁围成背油区，导油片11为螺旋结构，以便于将导油通道61底部的润滑油12泵送至导油通道61的上部，以便于对曲轴6的整体进行完全润滑，提高润滑效果。其中，曲轴6的侧壁上还设置有朝向泵体组件的导油孔，导油孔与迎油区或背油区连通。导油通道61的内壁上设置有连接凹槽，连接凹槽的一端与迎油区连通，连接凹槽的另一端与背油区连通，以使迎油区通过连接凹槽与背油区连通。
采用这样的结构设置，在运行过程中，由于迎油区通过连接凹槽与背油区连接，这样使得迎油区内的润滑油12和背油区内的润滑油12能够相互流动，从而提高了润滑油12在迎油区和背油区的均匀性，这样，导油孔无论与迎油区连通或是与背油区连通均能够使得有润滑油12顺利进入导油孔内，以便于使润滑有流经导油孔后对曲轴6与导油孔相对设置的泵体组件之间进行润滑，从而提高了对曲轴6的润滑效果。因此，通过本实施例提供的技术方案，能够解决现有技术中的曲轴6的润滑效果不佳的技术问题。
在本实施例中，导油通道61为圆柱形通道，连接凹槽的至少部分沿导油通道61的周向延伸，以便于更好地使迎油区和背油区连通，以更好的提高润滑油12的均匀性。
具体的，连接凹槽可以为螺旋油槽62，上述结构简单，便于生产制造，同时也便于迎油区和背油区的连通。
具体的，螺旋油槽62的横截面可以为半圆形、或梯形、或矩形、或三角形。
或者，本实施例中的连接凹槽可以为环形油槽63，环形油槽63的结构简单，便于生产制造，也便于迎油区和背油区的连通。
在本实施例中，导油孔的侧壁与连接凹槽的槽底相切。采用这样的结构设置，能够便于使得连接凹槽内的润滑油12顺利进入至导油孔内，从而便于更好地提高润滑油12的分布均匀性，从而便于更有利于曲轴6的润滑。
具体的，本实施例中的导油孔可以为多个，多个导油孔沿曲轴6的延伸方向间隔设置，连接凹槽为多个，多个连接凹槽与多个导油孔一一对应地设置，各个连接凹槽与相应的导油孔连通，以便于通过各个连接凹槽和相应的导油孔对曲轴6的不同部位进行润滑，从而便于更好地对曲轴6进行润滑。具体的，当连接凹槽为环形油槽63时，导油孔和连接凹槽可以均为多个。当连接凹槽为螺旋油槽62时，导油孔和连接凹槽可以均为多个；或者，螺旋油槽62为一个，螺旋油槽62设置较长的长度，导油孔设置多个。具体的，本实施例中的连接凹槽设置在导油片11的外部，连接凹槽的高度取决于导油片11的高度，连接凹槽的高度位置与导油片11的高度位置对应，以便于使导油片11处的迎油区和背油区的油液连通。
在本实施例中，曲轴6包括短轴段68和长轴段610，导油通道61贯通短轴段68和长轴段610，导油片11的至少部分位于短轴段68内，导油孔包括第一导油孔64，第一导油孔64设置在短轴段68内，连接凹槽包括第一连接凹槽，第一连接凹槽与第一导油孔64连通。泵体组件包括第一法兰10和第二法兰5，第一法兰10均套设在短轴段68上，第二法兰5套设在长轴段610上，第一法兰10位于第二法兰5的下方，第一法兰10为下法兰，第二法兰5为上法兰，第一导油孔64朝向短轴段68的径向设置。采用这样的结构设置，能够便于使得润滑油12经第一连接凹槽进入第一导油孔64，以便于对曲轴6和第一法兰10之间进行充分的润滑，从而便于提高对曲轴6的润滑效果。此处的连接凹槽可以为环形油槽63或螺旋油槽62结构。
具体的，本实施例中的短轴段68设置在长轴段610的下方，曲轴6在转动时带动导油片11同步转动，以便于将导油通道61内的润滑由短轴段68的底部向长轴段610的方向进行泵送，从而能够提高对曲轴6整体的润滑效果。第二导油孔65设置在曲轴6偏心部偏心较小的一端。
在本实施例中，曲轴6包括依次连接的短轴段68、偏心段69和长轴段610，导油通道61依次贯通短轴段68、偏心段69和长轴段610，导油片11位于短轴段68和偏心段69内，导油孔包括第二导油孔65，连接凹槽包括第二连接凹槽，第二导油孔65和连接凹槽均设置在偏心段69处，第二连接凹槽与第二导油孔65连通。采用这样的结构设置，能够便于通过第二连接凹槽和第二导油孔65对偏心段69进行润滑，从而便于提高对曲轴6的润滑效果。具体的，此处的连接凹槽可以为螺旋油槽62或环形油槽63结构。
在本实施例中压缩机1还包括壳体2、定子31、转子32、消音器4、气缸7、画片、滚子9和排气阀片13等。在工作时，滚子9外圆与滑片8的头部紧密配合，使得气缸7内圆与滚子9外圆形成的腔体被滑片8一分为二，形成吸气腔(低压腔)和压缩腔(高压腔)，制冷系统出来的低温低压制冷剂通过气缸7吸气孔进入吸气低压腔，在电机转子32的带动下曲轴6同步旋转，曲轴6偏心部上的滚子9也随之运转，气缸7吸气低压腔中的低温低压制冷剂在容积的变化下逐渐被压缩，然后被压缩成高温高压的制冷剂后从气缸7压缩高压腔的斜切口 流经法兰排气孔在排气阀片13开启后排出，最终回到制冷系统中，完成整个制冷循环的制冷剂压缩过程。
在压缩机1工作过程中，泵体组件内部润滑油12流通方式如下，压缩机1的壳体2底部的润滑油12浸至泵体组件的上法兰(第二法兰5)裙边处。压缩机1运行过程中，电机转子32带动曲轴6旋转，此时曲轴6也同步带动装配在其中心油孔处的导油片11旋转。具有螺旋结构的导油片11旋转使润滑油12从曲轴6短轴段68的底部流入其中心油孔，并沿着导油片11的外周棱线上升，润滑油12依次流入第一导油孔64、第二导油孔65、第三导油孔66和第四导油孔67。而后润滑油12分别流经下法兰(第一法兰10)的内孔油槽(第一连接凹槽)、曲轴6偏心部竖槽及上法兰内孔完成对曲轴6短轴与下法兰、曲轴6偏心部与滚子9、曲轴6长轴与上法兰间的润滑。并从上述下法兰内孔油槽及上法兰内孔螺旋油槽62的开孔端流出，在壳体2底部汇合。
当常规曲轴6短轴中心油孔装配导油片11后，当曲轴6短轴导油孔正好位于导油片11背油面一侧时，由于导油片11属于一种离心泵，润滑油12主要集中分布在其迎油面测，其背油面油量分布少，进而使曲轴6短轴导油孔流入油量少。最终影响曲轴6与下法兰间的润滑。
如图中所示，为曲轴6短轴中心油孔设置圆弧形螺旋油槽62并装配导油片11后，其导油孔位置处横截面示意图。此时，由于曲轴6中心油孔螺旋油槽62的存在连通了导油片11迎油面及背油面两侧，进而使得迎油面的润滑油12可以流入背油面，使两侧油量分布均匀。
具体的，由于螺旋油槽62设置与导油孔相切，使得导油片11迎油面润滑油12通过螺旋油槽62后更顺畅的流入导油孔，进一步增加了流入导油孔的油量。
如图中所示，螺旋油槽62还可以替换为曲轴6中心油孔环形油槽63，本质上一样，可理解为螺旋油槽62的一种变形。为减小曲轴6加工难度。只在曲轴6中心油孔内有导油孔位置处设置环形油槽63，同样，由于环形油槽63的存在连通了导油片11迎油面及背油面两侧，进而使得迎油面的润滑油12可以流入背油面，使两侧油量分布均匀。且环槽与导油孔相切，能使润滑油12更顺利的流入导油孔。
如图中所示，圆弧形螺旋油槽62可以替换为梯形螺旋油槽62，功能上与实施例一一致，起到导通导油片11两侧的作用。
本申请方案还适用单缸、双缸及以上的转子32式压缩机1等。本申请在曲轴6的中心油孔(中心油孔即为导油通道61)设置螺旋油槽62或环形油槽63结构，其起到连通导油片11的迎油面与背油面的作用，进而实现在导油片11泵油过程中导油片11两侧油量分布均匀。且由于螺旋油槽62和环形油槽63设置与导油孔相切，这使得曲轴6导油孔无论位于导油片11的迎油面还是背油面均保证流入油量的供应。
本申请的实施例二提供了一种空调器，空调器包括压缩机1，压缩机1为上述实施例提供的压缩机1。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：本申请解决了螺旋结构导油片在泵油过程中，迎油区和背油区的油量分布不均问题；解决当导油孔位于导油片背油区时，进油量少的问题。
