实施例一
如图1所示，一种压缩机，包括壳体1、一级压缩组件2、二级压缩组件3和连通管4。壳体1上设置有排气管9，一级压缩组件2具有第一进气通道5和第一排气通道6，二级压缩组件3具有第二进气通道7和第二排气通道8。第一排气通道6与壳体1的内腔连通。连通管4的两端分别与排气管9和第二进气通道7连接。冷媒从第一进气通道5进入一级压缩组件2、经一级压缩组件2压缩后通过第一排气通道6进入壳体1的内腔中，再依次流经排气管9和连通管4后，并通过第二进气通道7进入二级压缩组件3，经二级压缩组件3压缩后，从第二排气通道8排出。采用这样的技术方案，进入壳体1内腔中的冷媒是经过一级压缩组件2进行压缩后的中压冷媒，其相对于二级压缩组件3排出的高压冷媒来说压力较低，相对于现有技术，本实施例中的压缩机壳体1所承受的压力较低，因此在实际制作中，壳体1壁厚不需要太厚，进而能够降低制作成本。
如图1中所示，压缩机还包括用以为一级压缩组件2和二级压缩组件3提供动力的驱动装置10，并且一级压缩组件2、二级压缩组件3和驱动装置10均设置在壳体1的内腔中，并且一级压缩组件2和二级压缩组件3设置在驱动装置10的同一侧。这 样使本实施例中的结构更加简单，同时有利于对一级压缩组件2和二级压缩组件3和驱动装置10进行安装。
在一些实施例中，压缩机还包括增焓管32。其中增焓管32连接在一级压缩组件2和二级压缩组件3之间的冷媒流路上，使冷媒能够通过增焓管32进入一级压缩组件2和二级压缩组件3之间的冷媒流路中，并与经一级压缩组件2压缩的中压冷媒混合后再进入二级压缩组件3。这样能够实现对该压缩机进行补气增焓，进而使该压缩机的性能和可靠性得到了提升。其中，增焓管32可穿设在壳体1的壳壁上，并与壳体1的内腔连通，或者采用如图2中所示，直接将增焓管32连接在连通管4上。需要说明的是增焓管32的设置位置并不仅限于这两个位置，也可以设置在其他任意可实现本公开目的的位置。
如图1中所示，在一些实施例中，在连通管4上设置有第一冷却器33，使从排气管9排出的冷媒流经第一冷却器33后，经第二进气通道7进入二级压缩组件3，以降低进入二级压缩组件3的冷媒温度。
如图1中所示，在一些实施例中，在连通管4上设置有第一节流装置34，使从排气管9排出的冷媒流经第一节流装置34后，经第二进气通道7进入二级压缩组件3，以调节进入二级压缩组件3的冷媒的压力。
在实际制作中，如图1中所示，驱动装置10、一级压缩组件2和二级压缩组件3自上而下依次排布。压缩机还包括第一隔板11，一级压缩组件2包括第一上法兰12和第一气缸13。第一气缸13具有相背的第一上端面和第一下端面。第一上法兰12抵接在第一上端面上，第一隔板11抵接在第一下端面上，以使第一隔板11、第一上法兰12和第一气缸13共同形成第一压缩腔14。此时第一进气通道5可设置在第一气缸13和/或第一上法兰12上。也就是说第一进气通道5可以单独设置在第一气缸13或第一上法兰12上，也可以同时穿过第一气缸13和第一上法兰12。在实际制作中可如图1中所示，压缩机包括穿设在壳体1上的进气总管40，并根据实际情况将进气总管40设置在壳体1上与第一气缸13或第一上法兰12相对应的位置，提高了工作的适应性。
作为一种可实施方式，也可以如图3所示，在第一隔板11上设置有能够与第一压缩腔14连通的第一进气孔43，使冷媒能够通过第一进气孔43进入第一压缩腔14中。这样进气总管40设置在壳体1上与第一隔板11相对应的位置。需要说明的是第一进气孔43可以与第一进气通道5连通，即冷媒通过第一进气孔43进入第一进气通 道5。也可以采用第一进气孔43直接与第一压缩腔14连通，此时不需要在一级压缩组件2上设置第一进气通道5，冷媒直接通过第一进气孔43进入一级压缩组件2的第一压缩腔14中。
如图1中所示，第一排气通道6设置在第一上法兰12上，但并不仅限于此，也可以是其他任意可实现本公开目的的位置。此时增焓管32可以穿设在第一上法兰12的侧壁上，并与第一排气通道6连通。
在实际制作中，在驱动装置10和一级压缩组件2的排布方向上(即图1中的竖直方向)，第一上法兰12和驱动装置10之间的最小距离为3.5mm。这样不仅能够在保证驱动装置10与第一上法兰12存在安全距离的基础上，还能够避免因驱动装置10与第一上法兰12之间距离过大导致压缩机整体尺寸过大，有利于压缩机的小型化设计。
如图1、4所示，一级压缩组件2包括第一滚子15和第一滑片16。第一滚子15和第一滑片16均设置在第一气缸13的内腔中，第一滑片16铰接在第一滚子15上。第一滚子15和第一滑片16之间采用的这种滑片铰接方式并非是本公开的发明点，而是一种现有技术，本公开只是利用了这一现有技术，并不意图对其进行改进，因此对其工作原理此处不再一一详述。
在一些实施例中，如图1所示，二级压缩组件3包括第二气缸17和第一下法兰18。第二气缸17具有相背的第二上端面和第二下端面。第一隔板11抵接在第二上端面上，第一下法兰18抵接在第二下端面上，以使第一隔板11、第一下法兰18和第二气缸17共同形成第二压缩腔19。此时，第二进气通道7可设置在第二气缸17和/或第一下法兰18上。也就是说第二进气通道7可以单独设置在第二气缸17或第一下法兰18，也可以同时穿过第二气缸17和第一下法兰18。在实际制作中，连通管4可根据实际情况穿设在壳体1上与第二气缸17或第一下法兰18相对应的位置，提高了工作的适应性。
作为一种可实施方式，也可如图5所示，在第一隔板11上设置有能够与第二压缩腔19连通的第二进气孔44，连通管4通过第二进气孔与第二压缩腔19连通。这样连通管4设置在壳体1上与第一隔板11相对应的位置。需要说明的是第二进气孔44可以与第二进气通道7连通，即冷媒通过第二进气孔进入第二进气通道7。也可以采用第二进气孔44直接与第二压缩腔19连通，此时不需要在二级压缩组件3上设置第二进气通道，冷媒直接通过第二进气孔44进入二级压缩组件3的第二压缩腔19中。
在一些实施例中，第一压缩腔14的体积为V1，第二压缩腔19的体积为V2，并且0.6≤V2/V1≤0.9。这样可以使压缩机的性能系数达到最优的范围。
如图1所示，第二排气通道8设置在第二气缸17和/或第二下法兰23上。其设置原理与第二进气通道7的设置原理相同。在实际制作中可如图1中所示，压缩机包括穿设在壳体1上的排气总管41，并根据实际情况将排气总管41设置在壳体1上与第二气缸17或第一下法兰23相对应的位置，提高了工作的适应性。
作为一种可实施方式，如图6所示，第一隔板11上设置有能够与第二压缩腔19连通的第一排气孔45，使经二级压缩组件3压缩后的冷媒能够通过第一排气孔45流出。此时二级压缩组件3上可以不设置第二排气通道8，排气总管41可设置在壳体1上与第一隔板11相对应的位置。
二级压缩组件3包括第二滚子20和第二滑片21，第二滚子20和第二滑片21均设置在第二气缸17的内腔中，与第一滚子15和第一滑片16的连接方式相同，第二滑片21铰接在第二滚子20上(可参照图4)。
实施例二
本实施例中的压缩机与实施例一中所描述的压缩机的区别在于，如图7中所示，驱动装置10、二级压缩组件3和一级压缩组件2自上而下依次排布。压缩机还包括第二隔板22，一级压缩组件2包括第二下法兰23和第三气缸24。第三气缸24具有相背的第三上端面和第三下端面，第二下法兰23抵接在第三下端面上，第二隔板22抵接在第三上端面上，以使第二隔板22、第二下法兰23和第三气缸24共同形成第三压缩腔25。此时第一进气通道5设置在和/或第二下法兰23上。也就是说第一进气通道5可以单独设置在第三气缸24或第二下法兰23，也可以同时穿过第三气缸24和第二下法兰23。在实际制作中可如图7中所示，压缩机包括穿设在壳体1上的进气总管40，并根据实际情况将进气总管40设置在壳体1上与第三气缸24或第二下法兰23相对应的位置，提高了工作的适应性。
作为一种可实施方式，如图8所示，在第二隔板22上设置有能够与第三压缩腔25连通的第三进气孔46，使冷媒能够通过第三进气孔46进入第三压缩腔25中。这样进气总管40设置在壳体1上与第二隔板22相对应的位置。需要说明的是第三进气孔46可以与第一进气通道5连通，即冷媒通过第一进气孔46进入第一进气通道5。也可以采用第一进气孔46直接与第三压缩腔25连通，此时不需要在一级压缩组件2 上设置第一进气通道5，冷媒直接通过第一进气孔46进入一级压缩组件2的第三压缩腔25中。
如图7所示，第一排气通道6设置在第二下法兰23上。此时増焓管32穿设在第二法兰23的侧壁上，并与第一排气通道6连通，但増焓管32的设置位置并不仅限于此，也可以是其他任意可实现本公开目的的位置。在一些实施例中，第二下法兰23上设置有能够与第三压缩腔25连通的排气腔26，第三压缩腔25通过排气腔26与第一排气通道6连通，以使在第三压缩空间25压缩后的冷媒能够依次经过排气腔26和第一排气通道6进入壳体1的内腔中。此时增焓管32穿设在第二下法兰23的侧壁上，并与排气腔26连通。
一级压缩组件2包括第三滚子27和第三滑片，第三滚子27和第三滑片均设置在第三气缸24的内腔中，与第一滚子15和第一滑片16的连接方式相同，可采用第三滑片铰接在第三滚子27上(可参照图4)。
在一些实施例中，如图7所示，二级压缩组件3包括第四气缸28和第二上法兰29。第四气缸28具有相背的第四上端面和第四下端面。第二隔板22抵接在第四下端面上，第二上法兰29抵接在第四上端面上，以使第二隔板22、第二上法兰29和第四气缸28共同形成第四压缩腔30。此时第二进气通道7设置在第四气缸28和/或第二上法兰29上。也就是说第二进气通道7可以单独设置在第四气缸28或第二上法兰29上，也可以同时穿过第四气缸28和第二上法兰29。在实际制作中，连通管4可根据实际情况穿设在壳体1上与第四气缸28或第二上法兰29相对应的位置，提高了工作的适应性。
作为一种可实施方式，如图9所示，在第二隔板22设置有能够与第四压缩腔30连通的第四进气孔47，连通管4通过第四进气孔47与第四压缩腔30连通。这样连通管4设置在壳体1上与第二隔板22相对应的位置。需要说明的是第四进气孔47可以与第二进气通道7连通，即冷媒通过第四进气孔47进入第二进气通道7。也可以采用第四进气孔47直接与第四压缩腔30连通，此时不需要在二级压缩组件3上设置第二进气通道7，冷媒直接通过第四进气孔47进入二级压缩组件3的第四压缩腔30中。
在一些实施例中，如图7所示，第二排气通道8设置在第四气缸28的侧壁上和/或第二上法兰29上。其设置原理与第二进气通道7的设置原理相同。在实际制作中可如图1中所示，包括穿设在壳体1上的排气总管41，并根据实际情况将排气总管41设置在壳体1上与第四气缸28或第二上法兰29相对应的位置，提高了工作的适应 性。
作为一种可实施方式，如图8所示，第二隔板22上设置有与第四压缩腔30连通的第二排气孔48，使经二级压缩组件3压缩后的冷媒能够通过第二排气孔48流出。此时排气总管41可设置在壳体1上与第二隔板22相对应的位置。
在一些实施例中，如图7所示，当第一排气通道6设置在第二下法兰23上时，第三气缸24的侧壁上设置有第一连通孔，第二隔板22上设置有第二连通孔，第四气缸28的侧壁上设置有第三连通孔，第二上法兰29上设置有第四连通孔。第一连通孔、第二连通孔、第三连通孔和第四连通孔依次连接形成连通通道31。第一排气通道6通过连通通道31与壳体1的内腔连通。此时可如图10、11所示，增焓管32可穿设第三气缸24或第二隔板22或第四气缸28或第二上法兰29上并与连接通道31连通。
在一些实施例中，在驱动装置10和二级压缩组件3的排布方向上(即竖直方向)，第二上法兰29和驱动装置10之间的最小距离为3.5mm。这样不仅能够在保证驱动装置10与第二上法兰29存在安全距离的基础上，还能够避免因驱动装置10与第二上法兰29之间距离过大导致压缩机整体尺寸过大，有利于压缩机的小型化设计。
在一些实施例中，第三压缩腔25的体积为V3，第四压缩腔30的体积为V4，并且0.6≤V4/V3≤0.9。这样可以使压缩机的性能系数达到最优的范围。
在一些实施例中，二级压缩组件3包括第四滚子42和第四滑片；
第四滚子42和第四滑片均设置在第四气缸28的内腔中，与第一滚子15和第一滑片16的连接方式相同，第四滑片铰接在第四滚子42上(可参照图4)。
实施例三
如图12所示，一种制冷循环系统，包括第二冷却器35、蒸发器36和以上任意实施例的压缩机37，其中压缩机37为实施例一或实施例二中所描述的压缩机。第二冷却器35和蒸发器36串联在压缩机37的第一进气通道5和第二排气通道8之间，使从第二排气通道8排出的冷媒依次流经第二冷却器35和蒸发器36后，再通过第一进气通道5进入一级压缩组件2。
在一些实施例中，还包括经济器38，经济器38具有冷媒入口，气体冷媒出口和液体冷媒出口，第二排气通道8通过第二冷却器35与冷媒入口连通，以使从第二排气通道8排出的冷媒能够流经第二冷却器35后，通过冷媒入口进入经济器38中。液体冷媒出口通过蒸发器36与第一进气通道5连通，以使经经济器38分离出的液体冷 媒能够流经蒸发器36后，通过第一进气通道5进入一级压缩组件2。当压缩机37包括增焓管32时，气体冷媒出口与增焓管32连通，以使经经济器38分离出的气体冷媒能够通过增焓管32进入压缩机37中的一级压缩组件2和二级压缩组件3之间的流路中。
具体的工作过程为：从压缩机37的第二排气通道8排出的高温高压冷媒流经第二冷却器35放热后，变成气液两相冷媒进入经济器38，由经济器38闪发出的气体冷媒通过增焓管32进入压缩机57实现循环，经济器38中的液体冷媒流经蒸发器吸热后，变成气态冷媒进入压缩机37的一级压缩组件2实现循环。
在一些实施例中，还包括第二节流装置39。
液体冷媒出口通过第二节流装置39与蒸发器36连通，以使从液体冷媒出口排出的液体冷媒能够流经第二节流装置39后，再进入蒸发器36。这样可以通过第二节流装置39降低从液体冷媒出口排出的液体冷媒压力，进而使整个系统的压力保持稳定。
在该压缩机实际工作时，如图13所示，当冷媒进入一级压缩组件2时，对应a点。一级压缩组件2将冷媒压缩成中压冷媒并排入壳体1的内腔时，对应b点。冷媒通过增焓管32进入壳体1的内腔中，并与一级压缩组件2排出的中压冷媒混合，并对驱动装置10进行降温时，对应b点至c点。壳体1的内腔中的混合冷媒通过排气管9排出，经第一冷却器33放热时，对应d点至e点。通过第二进气通道7进入二级压缩组件3进行二次压缩时，对应c点至d点。进入第一节流装置34降压时，对应e点至f点。冷媒经二级压缩组件3进行二次压缩后可进入经济器38中，进入经济器38中的冷媒，一部分在经济器38中闪发后，通过增焓管32进入壳体1的内腔时，对应f点至c点。另一部分冷媒可通过第二节流装置39和蒸发器36降压后通过第一进气通道5进入一级压缩组件2时，对应i点至a点，从而形成制冷循环。采用这样的压缩方式，不仅能够提高制冷量，而且能够降低一级压缩组件2的吸气温度和二级压缩组件3的排气温度，同时分解压力比，减小了一级压缩组件和二级压缩组件之间的压力差，使压缩机的性能和可靠性得到了提高。
为实现本公开目的，本公开又一方面提供一种空调器，包括实施例三中所描述的制冷循环系统。
以上实施例使本公开具有能够降低壳体承受的压力，节约了制作成本的优点。
以上所述仅为本公开的实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的权利要求范围之内。
