Description

涡旋盘组件、涡旋压缩机和空调器
本申请要求于2021年03月30日提交到中国国家知识产权局的申请号为202110338891.1、发明名称为“涡旋盘组件、涡旋压缩机和空调器”的中国专利申请的优先权，并要求于2021年03月30日提交到中国国家知识产权局的申请号为202120640844.8、发明名称为“涡旋盘组件、涡旋压缩机和空调器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及压缩机技术领域，具体而言，涉及一种涡旋盘组件、一种涡旋压缩机和一种空调器。
背景技术
目前，涡旋压缩机的背压腔的压力为中间压力，动涡旋盘在背压腔压力作用下紧贴静涡旋盘，若背压腔压力过大，则会造成动涡旋盘与静涡旋盘贴合面摩擦损失增大，功率升高；若背压腔压力过小，则会造成动涡旋盘不能平稳地贴合静涡旋盘，容易导致动涡旋盘倾覆，并发生漏气现象，造成涡旋压缩机的工作能力下降。现有技术中通过在工作腔内设置背压孔的方案，使背压孔与背压腔连通，以使背压腔具有高于吸气压力的中间压力。但在该方案中，由于工作腔压力随静涡旋盘的运转而发生变化，当背压孔处的工作腔压力较高时，工作腔的气体容易通过背压孔进入背压腔内，当背压孔处的工作腔压力较低时，气体又容易通过背压孔进入工作腔，从而造成气体的流动损失，影响涡旋压缩机的能效。
发明内容
根据本申请的实施例，旨在至少改善现有技术或相关技术中存在的技术问题之一。
为此，根据本申请的实施例的一个目的在于提供一种涡旋盘组件。
根据本申请的实施例的另一个目的在于提供一种涡旋压缩机。
根据本申请的实施例的又一个目的在于提供一种空调器。
为了实现上述目的，根据本申请第一方面的实施例提供了一种涡旋盘组件，包括：静涡旋盘，静涡旋盘上设有进气孔、排气孔和注油通道；动涡旋盘，与静涡旋盘相啮合，并与静涡旋盘之间形成工作腔室，动涡旋盘上设有与涡旋压缩机的背压腔室相连通的注油槽，动涡旋盘配置为相对于静涡旋盘平动，以对进入工作腔室的气体进行压缩；其中，注油通道与注油槽和工作腔室间歇性地连通，以在背压腔室与工作腔室之间的压力差的作用下，使背压腔室中的油液间歇性注入工作腔室。
根据本申请第一方面的实施例，涡旋盘组件包括静涡旋盘和动涡旋盘，可用于涡旋压缩机。动涡旋盘与静涡旋盘相互啮合，并在二者之间围成工作腔室；动涡旋盘能够相对于静涡旋盘进行平动。通过在静涡旋盘上设置进气孔和排气孔，以使气体能够由进气孔进入工作腔室，以在动涡旋盘的运转过程中，改变工作腔室的结构状态，从而压缩气体，并使压缩后的气体通过排气孔排出至涡旋压缩机的排气腔室。
通过在静涡旋盘上设置注油通道，对应地，在动涡旋盘上设置注油槽，且注油槽能够与涡旋压缩机的背压腔室连通，以在动涡旋盘的运转过程中，注油槽能够间歇性地与注油通道以及工作腔室连通，并利用工作腔室与背压腔室之间的压力差，驱动背压腔室中的油液通过注油槽和注油通道流入工作腔室中，在对动涡旋盘与静涡旋盘之间的贴合面进行润滑的同时，并对工作腔室中的缝隙进行密封，防止工作腔室中的气体向背压腔室泄漏，同时，在注油槽与注油通道以及工作腔室处于断开连通的状态时，能够防止背压腔内的气体通过注油通道进入工作腔室，实现间歇性注油，从而在涡旋盘组件工作过程中减少气体的流动损失，有利于促进涡旋压缩机提高能效。
需要说明的是，涡旋压缩机的动涡旋盘与静涡旋盘之间的贴合面存在细微的缝隙，通常情况下，气体会在压力作用下流入或流出工作腔室，造成气体的流动损失。涡旋压缩机的背压腔的压力通常处于吸气压力与排气压力之间，涡旋压缩机的储油空间中的油液能够在压力作用下进入背压腔，从而为工作腔室提供油液。
另外，根据本申请的实施例中提供的上述技术方案中的涡旋盘组件还可以 具有如下附加技术特征：
在上述技术方案中，在工作腔室的压力大于背压腔室的压力时，注油通道与注油槽和工作腔室断开连通；在工作腔室的压力小于背压腔室的压力时，注油通道与注油槽和工作腔室连通。
在该技术方案中，随着工作腔室内的压力变化，注油通道与注油槽以及工作腔室交替连通和断开。当工作腔室的压力大于背压腔室的压力时，通过动涡旋盘的运转，断开注油通道与注油槽以及工作腔室之间的连通关系，以防止工作腔室中的气体通过注油通道和注油槽进入背压腔，以减少气体损失；而当工作腔室的压力小于背压腔室的压力时，通过动涡旋盘的运转，使注油通道与注油槽以及工作腔室连通，此时，在背压腔与工作腔室之间形成压力差，背压腔的油液在压力作用下通过注油槽和注油通道进入工作腔室，以对工作腔室的缝隙进行密封，防止气体通过缝隙泄漏至背压腔。以上设置既能够减少工作腔室的缝隙造成的气体流动损失，同时能够防止注油通道和注油槽自身造成气体损失，对涡旋压缩机的能效的改善效果更佳。

下面参照图1至图26描述根据本申请一些实施例的涡旋盘组件、涡旋压缩机和空调器。
实施例一
本实施例提供了一种涡旋盘组件1，可用于涡旋压缩机2。
如图1和图2所示，涡旋盘组件1包括静盘11(即静涡旋盘)和动盘12(即动涡旋盘)。动盘12与静盘11相互啮合，并与静盘11之间围成工作腔室13。
动盘12能够相对于静盘11进行平动，且在动盘12运转过程中，工作腔室13的形态和体积发生动态变化。
静盘11上设置进气孔113和排气孔114；在装配于涡旋压缩机2时，进气孔113与涡旋压缩机2的进气管211连通，排气孔114与涡旋压缩机2的排气腔室214连通。
在涡旋压缩机2工作过程中，气体能够由进气孔113进入工作腔室13，并在动盘12的作用下对工作腔室13中的气体进行压缩；完成压缩的气体能够排气孔114排出至涡旋压缩机2的排气腔室214，进而通过排气管212向外界排出。
其中，如图3和图4所示，静盘11上设置有注油通道115，与之相对应，动盘12上设置有注油槽123，且注油槽123能够与涡旋压缩机2的背压腔室213连通。在动盘12的运转过程中，注油槽123能够间歇性地与注油通道115以及工作腔室13连通，使背压腔室213与工作腔室13实现连通，也能够使注油槽123间歇性与注油通道115以及工作腔室13断开连接关系。
工作腔室13与背压腔室213之间存在压力差，背压腔室213中的油液能够在压力作用下，通过注油槽123和注油通道115流入工作腔室13中，实现 间歇性注油，以对动盘12与静盘11之间的贴合面进行润滑，同时，对工作腔室13中的缝隙进行密封。
需要说明的是，涡旋压缩机2的动盘12与静盘11之间的贴合面存在细微的缝隙，通常情况下，气体会在压力作用下流入或流出工作腔室13，造成气体的流动损失。
本实施例中的涡旋盘组件1，能够有效防止工作腔室13中的气体向背压腔室213泄漏，并能够防止背压腔室213内的气体通过注油通道115进入工作腔室13，从而在涡旋盘组件1工作过程中减少气体的流动损失，有利于促进涡旋压缩机2提高能效。
可以理解地，涡旋压缩机2的背压腔室213的压力通常处于吸气压力与排气压力之间，涡旋压缩机2的储油空间中的油液能够在压力作用下进入背压腔室213，从而为工作腔室13提供油液。
实施例二
本实施例提供了一种涡旋盘组件1，在实施例一的基础上做了进一步的改进。
如图1至图4所示，随着工作腔室13内的压力变化，注油通道115与注油槽123以及工作腔室13交替连通和断开。
当工作腔室13的压力大于背压腔室213的压力时，此时工作腔室13的压力较高，通过动盘12的运转，断开注油通道115与注油槽123以及工作腔室13之间的连通关系，以防止工作腔室13中的气体通过注油通道115和注油槽123进入背压腔室213，以减少气体损失。
当工作腔室13的压力小于背压腔室213的压力时，此时工作腔室13的压力较低，通过动盘12的运转，使注油通道115与注油槽123以及工作腔室13连通，背压腔室213与工作腔室13之间形成压力差，使背压腔室213的油液在压力作用下通过注油槽123和注油通道115进入工作腔室13，以对工作腔室13的缝隙进行密封，防止气体通过缝隙泄漏至背压腔室213。
本实施例中的设置方式能够减少工作腔室13的缝隙造成的气体流动损失，同时能够防止注油通道115和注油槽123自身造成气体损失，对涡旋压缩机2的能效的改善效果更佳。
实施例三
本实施例提供了一种涡旋盘组件1，在实施例二的基础上做了进一步的改进。
如图1至图4所示，静盘11具体包括静盘端板111(即第一端板)和静盘涡卷112(即静涡旋结构)。静盘涡卷112设于静盘端板111的底面，并呈涡旋状设置。排气孔114位于静盘涡卷112中，以便于排气。
如图5和图6所示，注油通道115具体包括注油孔1151、连接孔和背压孔1153，背压孔1153设于静盘端板111的底面上，注油孔1151设于静盘涡卷112的底面上，且注油孔1151和背压孔1153均为盲孔；连通孔1152设于静盘端板111和静盘涡卷112内部，且连通孔1152的两端分别于注油孔1151和背压孔1153连通，从而形成贯通的注油通道115。
在涡旋压缩机2工作过程中，动盘12相对于静盘11进行平动，并使背压孔1153交替打开和关闭，同时，注油槽123于注油孔1151交替连通和断开，进而使涡旋压缩机2的背压腔室213与工作腔室13实现交替性连通和断开。
需要说的是，本实施例中的底面、顶面均以静盘11在装配状态下的高度方向作为参照，例如图1和图2中的状态；图3中示出的是静盘11的下部结构示意图，并非在装配状态下的方向。
实施例四
本实施例提供了一种涡旋盘组件1，在实施例三的基础上做了进一步的改进。
如图1至图4所示，动盘12具体包括动盘端板121(即第二端板)和动盘涡卷122(即动涡旋结构)，动盘涡卷122设于动盘端板121的顶面上，并形成与静盘涡卷112相适配的涡旋状设置。动盘涡卷122与静盘涡卷112相啮合，并与静盘涡卷112围成工作腔室13。
其中，随着动盘12的运转，工作腔室13的形状和体积会发生变化。动盘端板121的顶面上位于动盘涡卷122的外侧的位置设有注油槽123，以在动盘端板121的顶面与静盘涡卷112的底面贴合后，注油槽123能够随动盘12的运转间歇性与注油孔1151连通和断开。
其中，注油槽123的一端延伸至动盘端板121的边缘，以在涡旋盘组件1 装配与涡旋压缩机2时，注油槽123能够与涡旋压缩机2的背压腔室213连通；注油槽123的另一端向靠近动盘涡卷122的方向延伸，以与注油孔1151的位置相对应，以能够与注油孔1151连通，便于进行注油操作。
进一步地，背压孔1153的孔径小于动盘涡卷122的齿厚，使得动盘涡卷122在运动至背压孔1153的位置时，能够完全封挡背压孔1153，以使背压孔1153与工作腔室13实现交替性连通和断开，进而防止背压孔1153与动盘涡卷122的尺寸不匹配而导致气体通过背压孔1153向背压腔室213泄漏。
实施例五
本实施例提供了一种涡旋盘组件1，在实施例四的基础上做了进一步的改进。
如图7所示，注油槽123靠近动盘涡卷122的一端为圆弧结构，具体为半圆结构，便于加工成型，在油液流过时能够对油液起导引作用。
注油槽123的槽宽与圆弧结构的直径相等，使得注油槽123整体形成等宽度的长条状槽体，易于加工，且在油液流过时能够减少因宽度变化而引起油液的压力变化。
进一步地，注油槽123的槽宽尺寸大于或等于1mm，槽深大于或等于0.5mm，以在动盘端板121与静盘11贴合时，使注油槽123能够保持合适的过流面积，防止注油槽123过窄而影响油液的正常流动。
实施例六
本实施例提供了一种涡旋盘组件1，在实施例四的基础上做了进一步的改进。
如图1、图2和图8所示，动盘端板121的底部设置有偏心轴承124。在涡旋盘组件1装配于涡旋压缩机2时，偏心轴承124能够与驱动机构的偏心部件(例如曲轴)连接，从而实现动盘12的偏心连接。在涡旋压缩机2工作时，动盘12能够在驱动机构的偏心部件的带动下，相对于静盘11进行平动，以对气体进行压缩。
实施例七
本实施例提供了一种涡旋盘组件1，在实施例四的基础上做了进一步的改进。
如图1至图3以及图9所示，静盘11的静盘端板111包括底壁1111和侧壁1112，侧壁1112沿底壁1111的圆周方向设置，静盘涡卷112位于侧壁1112的内侧。进气孔113沿静盘端板111的径向方向设置，以便于连接涡旋压缩机2的进气管211；同时，进气孔113穿过静盘端板111的侧壁1112，以便于能够与工作腔室13形成连通。
当进气孔113与工作腔室13处于连通状态时，进行吸气操作，气体通过进气孔113进入工作腔室13；随着动盘12的运转，进气孔113与工作腔室13之间断开，进而对工作腔室13内的气体进行压缩操作，压缩后的气体通过排气孔114排放至涡旋压缩机2的排气腔室214，完成一次工作循环。
其中，进气孔113的中心线与背压孔1153之间存在夹角β，以使背压孔1153和进气孔113之间保持合适的间隔，具体地，如图9所示，在静盘涡卷112逐渐缩小的方向上(即图9中的逆时针方向)，进气孔113的中心线绕静盘11的中心点旋转夹角β至背压孔1153的中心点，且225°≤夹角β≤315°，在该范围内，背压孔1153能够获得较优的背压压力。
实施例八
本实施例提供了一种涡旋盘组件1，在实施例四的基础上做了进一步的改进。
如图1至图4所示，进气孔113延伸至静盘涡卷112的外侧，而背压孔1153位于静盘涡卷112的内侧。在动盘12的运转过程中，动盘12能够将背压孔1153与进气孔113隔开，使背压孔1153始终与进气孔113保持断开状态，以防止注油操作对吸气过程造成影响，同时在压缩过程中，也能够防止气体由进气孔113向外泄漏。
实施例九
本实施例提供了一种涡旋盘组件1，在实施例四的基础上做了进一步的改进。
如图1、图2和图10所示，工作腔室13包括第一腔室131和第二腔室132。具体地，动盘涡卷122的外侧面与静盘涡卷112的内侧面之间形成第一腔室131，动盘涡卷122的内侧面与静盘涡卷112的外侧面之间形成第二腔室132。
随着动盘12的运转，第一腔室131和第二腔室132的形状和体积发生周 期性变化。在此过程中，背压孔1153与第一腔室131以及第二腔室132交替形成连通，且在动盘涡卷122封挡背压孔1153时，断开背压孔1153与第一腔室131和第二腔室132之间的连通关系。
其中，由于背压腔室213与工作腔室13之间的压力差的存在，随着动盘12的运转，背压腔室213的油液能够在压力作用下，交替向第一腔室131和第二腔室132内注油，以分别对第一腔室131和第二腔室132的缝隙进行密封，进一步防止工作腔室13中的气体通过缝隙向外泄漏。
进一步地，动盘12相对于静盘11平动一周为一个工作循环。在一个工作循环过程中，第一腔室131和第二腔室132分别与背压孔1153连通一次，相应地，背压腔室213向第一腔室131和第二腔室132各注油一次，以使注油操作与动盘12的工作循环相匹配。其中，在两次注油过程之间，背压孔1153关闭，以防止气体由背压孔1153反向流入背压腔室213。
实施例十
本实施例提供了一种涡旋盘组件1，在实施例九的基础上做了进一步的改进。
第一腔室131的最大容积大于第二腔室132的最大容积，即第一腔室131与第二腔室132的最大容积不同，二者之间存在容积差。其中，第一腔室131与背压腔室213的连通时长大于或等于第二腔室132与背压腔室213的连通时长，即背压腔室213与第一腔室131的连通时长不小于背压腔室213与第二腔室132的连通时长，以使第一腔室131和第二腔室132各自与背压腔室213的连通时长与各自的最大容积相匹配，实现第一腔室131和第二腔室132不同的排气量，以便于应用于非对称型线涡旋压缩机。
以下提供上述涡旋盘组件1的一个具体实施例：

如图1至图4所示，动盘12具体包括动盘端板121(即第二端板)和动盘涡卷122(即动涡旋结构)，动盘涡卷122设于动盘端板121的顶面上，并形成与静盘涡卷112相适配的涡旋状设置。动盘涡卷122与静盘涡卷112相啮合，并与静盘涡卷112围成工作腔室13。
动盘12能够相对于静盘11进行平动，在涡旋压缩机2工作过程中，气体能够由进气孔113进入工作腔室13，并在动盘12的作用下对工作腔室13中的气体进行压缩；完成压缩的气体能够排气孔114排出至涡旋压缩机2的排气腔室214，进而通过排气管212向外界排出。
如图3和图4所示，静盘11上设置有注油通道115，与之相对应，动盘12上设置有注油槽123，且注油槽123能够与涡旋压缩机2的背压腔室213连通。
如图5和图6所示，注油通道115具体包括注油孔1151、连接孔和背压孔1153，背压孔1153设于静盘端板111的底面上，注油孔1151设于静盘涡卷112的底面上，且注油孔1151和背压孔1153均为盲孔；连通孔1152设于静盘端板111和静盘涡卷112内部，且连通孔1152的两端分别于注油孔1151和背压孔1153连通，从而形成贯通的注油通道115。
如图7所示，动盘端板121的顶面上位于动盘涡卷122的外侧的位置设有注油槽123，注油槽123的一端延伸至动盘端板121的边缘，以在涡旋盘组件1装配与涡旋压缩机2时，注油槽123能够与涡旋压缩机2的背压腔室213连通；注油槽123的另一端向靠近动盘涡卷122的方向延伸，以与注油孔1151的位置相对应，以能够与注油孔1151连通，便于进行注油操作。
在动盘12的运转过程中，注油槽123能够间歇性地与注油通道115以及工作腔室13连通，使背压腔室213与工作腔室13实现连通，也能够使注油槽123间歇性与注油通道115以及工作腔室13断开连接关系。在此过程中，动盘12能够将背压孔1153与进气孔113隔开，使背压孔1153始终与进气孔113保持断开状态，以防止注油操作对吸气过程造成影响。
其中，如图5和图7所示，背压孔1153的孔径小于动盘涡卷122的齿厚，使得动盘涡卷122在运动至背压孔1153的位置时，能够完全封挡背压孔1153，以使背压孔1153与工作腔室13实现交替性连通和断开。
工作腔室13与背压腔室213之间存在压力差，背压腔室213中的油液能够在压力作用下，通过注油槽123和注油通道115流入工作腔室13中，实现间歇性注油。
具体地，当工作腔室13的压力大于背压腔室213的压力时，此时工作腔室13的压力较高，通过动盘12的运转，断开注油通道115与注油槽123以及工作腔室13之间的连通关系，以防止工作腔室13中的气体通过注油通道115和注油槽123进入背压腔室213，以减少气体损失。
当工作腔室13的压力小于背压腔室213的压力时，此时工作腔室13的压力较低，通过动盘12的运转，使注油通道115与注油槽123以及工作腔室13连通，背压腔室213与工作腔室13之间形成压力差，使背压腔室213的油液在压力作用下通过注油槽123和注油通道115进入工作腔室13，以对工作腔室13的缝隙进行密封，防止气体通过缝隙泄漏至背压腔室213。
如图7所示，注油槽123靠近动盘涡卷122的一端为圆弧结构，具体为半圆结构，便于加工成型，在油液流过时能够对油液起导引作用。注油槽123的槽宽与圆弧结构的直径相等，使得注油槽123整体形成等宽度的长条状槽体，易于加工，且在油液流过时能够减少因宽度变化而引起油液的压力变化。
其中，注油槽123的槽宽尺寸大于或等于1mm，槽深大于或等于0.5mm，以在动盘端板121与静盘11贴合时，使注油槽123能够保持合适的过流面积，防止注油槽123过窄而影响油液的正常流动。
如图1、图2和图8所示，动盘端板121的底部设置有偏心轴承124，以在涡旋盘组件1装配于涡旋压缩机2时，用于连接驱动机构的偏心部件(例如 曲轴)。
如图9所示，进气孔113的中心线与背压孔1153之间存在夹角β，以使背压孔1153和进气孔113之间保持合适的间隔，具体地，在静盘涡卷112逐渐缩小的方向上(即图9中的逆时针方向)，进气孔113的中心线绕静盘11的中心点旋转夹角β至背压孔1153的中心点，且225°≤夹角β≤315°，在该范围内，背压孔1153能够获得较优的背压压力。
如图1、图2和图10所示，工作腔室13包括第一腔室131和第二腔室132。具体地，动盘涡卷122的外侧面与静盘涡卷112的内侧面之间形成第一腔室131，动盘涡卷122的内侧面与静盘涡卷112的外侧面之间形成第二腔室132。
随着动盘12的运转，第一腔室131和第二腔室132的形状和体积发生周期性变化，且第一腔室131的最大容积大于第二腔室132的最大容积，对应地，第一腔室131与背压腔室213的连通时长大于第二腔室132与背压腔室213的连通时长，以便于应用于非对称型线涡旋压缩机。在此过程中，背压孔1153与第一腔室131以及第二腔室132交替形成连通，且在动盘涡卷122封挡背压孔1153时，断开背压孔1153与第一腔室131和第二腔室132之间的连通关系。
其中，动盘12相对于静盘11平动一周为一个工作循环。在一个工作循环过程中，第一腔室131和第二腔室132分别与背压孔1153连通一次，相应地，背压腔室213向第一腔室131和第二腔室132各注油一次，以使注油操作与动盘12的工作循环相匹配。其中，在两次注油过程之间，背压孔1153关闭，以防止气体由背压孔1153反向流入背压腔室213。
以下具体说明动盘12在一个工作循环内的工作过程：
图10和图11示出了背压孔1153被动盘涡卷122封挡时的状态，此时，注油槽123与注油孔1151已断开一段时间，背压孔1153刚与第二腔室132断开。随着动盘12继续运转，背压孔1153即将进入第一腔室131，如图12和图13所示的状态。
图14和图15示出了背压孔1153与第一腔室131连通时的状态，此时，注油槽123与注油孔1151也连通，使得背压腔室213与第一腔室131处于连通状态，由于背压孔1153处的第一腔室131的压力较低(低于背压腔室213的压力)，背压腔室213中的油液在压力作用下进入第一腔室131。
随着动盘12的进行运转，如图16和图17所示的状态，背压孔1153与第一腔室131仍然连通，但注油槽123与注油孔1151断开。此时，背压孔1153处的第一腔室131的压力较高(高于背压腔室213的压力)，但第一腔室131内的气体无法进入背压腔室213。
图18和图19示出了背压孔1153被动盘12封挡时的状态，此时，注油槽123与注油孔1151已断开一段时间，而背压孔1153刚与第一腔室131断开。随着动盘12继续运转，背压孔1153即将进入第二腔室132，如图20和图21所示的状态。
图22和图23示出了背压孔1153与第二腔室132连通时的状态，此时，注油槽123与注油孔1151也连通，使得背压腔室213与第二腔室132处于连通状态，由于背压孔1153处的第二腔室132的压力较低(低于背压腔室213的压力)，背压腔室213中的油液在压力作用下进入第二腔室132。
随着动盘12的进行运转，如图24和图25所示的状态，背压孔1153与第二腔室132仍然连通，但注油槽123与注油孔1151断开。此时，背压孔1153处的第二腔室132的压力较高(高于背压腔室213的压力)，但第二腔室132内的气体无法进入背压腔室213。
需要说明的是，涡旋压缩机2的动盘12与静盘11之间的贴合面存在细微的缝隙，通常情况下，气体会在压力作用下流入或流出工作腔室13，造成气体的流动损失。
本实施例中的涡旋盘组件1，能够有效防止工作腔室13中的气体向背压腔室213泄漏，并能够防止背压腔室213内的气体通过注油通道115进入工作腔室13，从而在涡旋盘组件1工作过程中减少气体的流动损失，有利于促进涡旋压缩机2提高能效。

壳体21上设有进气管211和排气管212，进气管211与静盘11的进气孔113连通，静盘11的排气孔114通过壳体21内的排气腔室214与排气管212连通，以便于进行吸气和排气操作。壳体21内储存有油液，且油液能够通过油道进入背压腔室213。
其中，随着动盘12的运转，静盘11的注油通道115能够间歇性与动盘12的注油槽123以及工作腔室13连通，以实现背压腔室213与工作腔室13之间的间歇性连通和断开，进而利用背压腔室213与工作腔室13之间的压力差，使背压腔室213内的油液间歇性注入工作腔室13内，以对工作腔室13内的缝隙进行密封。
本实施例中的涡旋压缩机2，能够有效防止工作腔室13的气体泄漏，同时，能够防止工作腔室13内的气体通过供油通道和注油槽123进入背压腔室213，从而有效减少涡旋压缩机2工作过程中的气体流动损失，有利于促进涡旋压缩机2提高能效。

此外，本实施例中的空调器3还具有上述任一实施例中的涡旋压缩机2的全部有益效果，在此不再赘述。
以下提供了本申请的一个具体实施例：
一种涡旋式压缩机压缩结构，包括：壳体、曲轴、动盘和静盘。壳体为设有吸气管和排气管的密闭容器，壳体内为高压环境，储存有润滑油；曲轴具有偏心部，并绕固定轴旋转；动盘具有镜板，立于镜板正面的涡旋状涡卷；静盘开设有吸气孔和排气孔，并具有内凹的涡旋状涡卷。静盘涡卷与动盘涡卷啮合形成压缩机工作腔。工作腔通过吸气管从壳体吸入口吸入低压气体，低压气体被压缩并经过静盘排气孔排出至壳体内，最后从壳体排气管排出。
该工作腔包括：动盘涡卷的外线与静盘涡卷内线之间的A腔(即第一腔室)，动盘涡卷的内线与静盘涡卷外线之间的B腔(即第二腔室)；背压腔室，背压腔室压力为处于吸气压力和排气压力的中间压力，背压腔室为动盘镜板正面紧贴静盘顶面提供支撑力防止动盘倾覆。背压孔，背压孔开设在静盘的内顶面，随着动盘运动，背压孔与A腔和B腔交替连通，交替时背压孔被动盘涡卷覆盖；注油孔，注油孔开设在静盘涡卷的底面，与背压孔连通；注油槽，注油槽开设在动盘镜板正面，与背压腔室连通；
其中，随着动盘运动，注油槽与注油孔间歇性连通，而且在背压孔压力升高过程中，在背压孔被动盘涡卷覆盖前，注油槽与注油孔断开连通。
注油孔开设在静止的静盘上，注油槽开设在平面运动的动盘上，通过对注油槽的位置进行设计，能够使得注油槽与注油孔间歇性连通和断开，而且保证在背压孔压力升高过程中，在背压孔被动盘涡卷覆盖前，注油槽与注油孔断开连通。即背压孔处工作腔压力较低时，工作腔与背压腔室连通；背压孔处工作腔压力较高，工作腔与背压腔室断开。防止了工作腔的气体进入到背压腔室，减少了呼吸损失。而由于背压腔室的压力低于排气压力，壳体内的润滑油通过压差进入到背压腔室。当注油槽与注油孔连通时，由于此时背压孔处工作腔压力比背压腔室压力低，润滑油被从背压腔室注入到工作腔，实现工作腔供油进行间隙密封，防止气体泄漏。
壳体设有吸气管和排气管，底部储存有润滑油。动盘具有镜板和立于镜板正面的涡旋状涡卷，凸出镜板背面的偏心轴承，镜板正面开设有注油槽。静盘开设有吸气孔和排气孔，内凹的涡旋状涡卷，背压孔开设在静盘的内顶面，注油孔开设在静盘涡卷的底面，两孔通过一径向连通孔相互连通。静盘涡卷与动盘涡卷啮合形成压缩机工作腔。动盘涡卷的外线与静盘涡卷内线之间的A工 作腔，动盘涡卷的内线与静盘涡卷外线之间的B工作腔；压缩机还设有主机架，支撑曲轴。
动盘镜板背面形成有背压腔室，背压腔室由主机架、静盘和动盘三者围成。动盘上的注油槽与镜板边缘贯通，即注油槽与背压腔室连通。
一方面，背压腔室与壳体内高压通过微小间隙连通；另一方面当背压孔与A或B工作腔连通，且注油槽与注油孔也连通时，背压腔室与工作腔连通；由此背压腔室处于高压和低压之间的中间压力，为动盘镜板正面紧贴静盘顶面提供支撑力防止动盘倾覆。润滑油被从壳体内压入背压腔室，后注入到工作腔，实现工作腔供油进行间隙密封，防止气体泄漏。
在背压孔压力升高过程中，在背压孔被动盘涡卷覆盖前，注油槽与注油孔断开，背压孔与背压腔室断开连通。
注油槽由两条平行线和圆弧组成，槽宽等于圆弧直径，槽宽大于等于1mm，槽深大于等于0.5mm。注油槽简单容易加工。
吸气孔中心线绕静盘中心向涡卷缩小方向旋转β角经过背压孔，β大于等于225°且小于等于315°。由此能获得较优的背压压力。
对于非对称型线涡旋压缩机，A工作腔容积大于B工作腔，因此优选背压腔室与A腔的连通时间不小于背压腔室与B腔的连通时间。
为防止往工作腔内喷油时影响吸气，优选背压孔不与静盘吸气孔连通。背压孔即将与A/B腔连通时，A/B腔已完成吸气闭合。
以上结合附图详细说明了根据本申请的一些实施例的技术方案，能够有效防止工作腔室中的气体向背压腔室室泄漏，并能够防止背压腔室内的气体通过注油通道进入工作腔室，从而在涡旋盘组件工作过程中减少气体的流动损失，有利于促进涡旋压缩机提高能效。
