本公开涉及空调技术领域，具体涉及一种吸气装置、压缩组件和空调器。
背景技术
转子压缩机具有结构简单、成本相对较低、能效高的优势在市场中得到广泛的推广和应用，而且转子压缩机在现有基础上的核心竞争力则在于提高能效、降低成本和拓宽应用范围。因此具备以上特性的小型高速以及大排量转子压缩机正在逐步抢占市场。由于小型高速和大排量转子压缩机拥有一个共同的特点：压缩机冷媒吸气流速和流量较大，常规分液器自身滤网和滤网支架等结构的限制使得压缩机吸气阻力较大，在很大程度上影响了压缩机的能效。相关技术虽然公开了滤网设在吸气管的铜管口，其目的是为了增加分液器内部的容积来提升制冷量，对于小型高速和大排量转子压缩机来说同样存在由于滤网阻力大导致压缩机制冷量低的难题；又由于压缩机的两个气缸吸气时常规分液器的两个出气管气流脉动较大，两者相互干扰导致压缩机功耗较高，同样影响压缩机的能效。相关技术仅公开了常规内置滤网分液器的结构，主要是过滤杂质解决压缩机的可靠性，同存在上述能效问题。常规分液器外观尺寸较大，在空调系统中安装空间有限，难以实现装配。
由于相关技术中的传统压缩机的吸气阻力大、导致输气量低、能效低、功耗高等问题，因此本公开研究设计出一种吸气装置、压缩组件和空调器。

具体实施方式
实施例1：
本公开提出的一种特殊吸气结构的新型转子压缩机及其空调器，主要包括：压缩机吸气装置、泵体组件、电机定子、电机转子、壳体组件和空调循环系统等。压缩机吸气装置、泵体组件、电机定子、电机转子和壳体组件等共同组成压缩机本体。其中压缩机吸气装置包括：进气管、上端盖、筒体、第一出气管、第二出气管和下端盖。泵体组件包括：曲轴、上法兰、第一气缸、隔板、第二气缸下法兰和下盖板。空调循环系统主要包括：冷凝器、蒸发器、过滤装置1(包括滤网1b)和其他空调系统；其中：
如图1所示，泵体组件位于壳体组件11内部并与其通过机械部固定连接。电机转子12嵌套在泵体组件的曲轴14上，两者同轴心过盈配合。电机定子13位于壳体组件11内部且嵌套在电机转子上，电机定子13与壳体组件11过盈配合，与电机转子12间隙同轴心配合。上盖组件10和下盖组件21分别位于壳体组件11的上下两端，三者形成压缩机本体的密封腔体。泵体组件中，上法兰15、第一气缸16、隔板17、第二气缸18、下法兰19和下盖板20从上到下依次转过曲轴14并与其同轴心装配。吸气装置4的上端盖3和下端盖9分别位于筒体5的两端，进气管2穿过上端盖与筒体5连通。第一出气管6和第二出气管7的上端分别穿过下端盖与筒体5连通，下端穿过壳体组件11分别与泵体组件的第一气缸16和第二气缸18连通。
如图1所示，本公开提供一种吸气装置，其中：
包括筒体5、进气管2、第一出气管6和第二出气管7，所述进气管2一端从所述筒体5的第一端与所述筒体5的内部连通、被设置为将流体通入所述筒体5的内部，所述第一出气管6的一端从所述筒体5的第二端与所述筒体5的内部连通、以将所述筒体5内的部分流体从所述第一出气管6导出，所述第二 出气管7的一端从所述筒体5的第二端与所述筒体5的内部连通、以将所述筒体5内的部分流体从所述第二出气管7导出，且所述进气管2的流通面积为S，所述第一出气管6的流通面积为S1，所述第二出气管7的流通面积为S2，并有S≥S1+S2(主实施例，参见附图1)。
由于相关技术中的传统压缩机的吸气阻力大、导致输气量低、能效低、功耗高，并且内置滤网和滤网支架导致分液器吸气阻力大，压缩机的两个气缸吸气时分液器的两个出气管气流脉动较大，两者相互干扰导致压缩机功耗较高，同样影响压缩机的能效等问题。为解决上述问题，本公开提出了一种特殊吸气结构的新型转子压缩机，去除了常规的压缩机分液器，对吸气管路结构以及管径进行了优化设计，大幅降低了转子压缩机的吸气阻力，有效的提高了压缩机的能效。
本公开通过将吸气装置中的进气管流通面积S、第一出气管的流通面积S1和第二出气管的流通面积为S2设置为满足关系S≥S1+S2，使得压缩机吸气装置的进气管管径与出气管满足一定的数值关系，能够有效减小吸气阻力，增大压缩机的输气量，有效提高了压缩机的能效，减小功耗。为了尽量减小压缩机吸气阻力提升其能效，吸气装置4需满足如下结构关系：第一出气管6和第二出气管7的有效流通面积分别为S1和S2，进气管2的有效流通面积为S，满足S≥S1+S2，优选S1＝S2，即满足S≥2S1。
本公开提出的一种特殊吸气结构的新型转子压缩机及其空调器，采用外置滤网结构的吸气装置，与常规内置滤网和滤网支架分液器相比降低了转子压缩机吸气装置内的气流阻力；吸气装置的不等高出气管结构设计降低了压缩机两个气缸的吸气脉动干扰，使压缩机吸气更顺畅，降低了压缩机的功耗；转子压缩机吸气装置的进气管管径与出气管满足一定的数值关系，减小了吸气阻力，增大了压缩机的输气量，有效提高了压缩机的能效。该吸气装置结构紧凑，相对减小了压缩机的外观尺寸，使得压缩机在空调系统匹配时压缩机更容易实现装配。该结构还具有加工简单、实用性强、成本低、便于推广等优点。
替代实施例：
如图3所示，与主实施例不同的是吸气装置4可由进气管2和第一出气管6和第二出气管7组成，进气管2的下端面为封闭状态，第一出气管6和第二出气管7的一端分别穿过进气管2的侧壁并与其连通，同样的第一出气管6和第二出气管7的一端分别穿过壳体组件11分别与泵体组件的第一气缸16和第二气缸18连通。第一出气管6和第二出气管7的有效流通面积分别为S1和 S2，满足S1＝S2，进气管2的有效流通面积为S，满足S≥2S1；过滤装置1的进出口管道有效流通面积和过滤装置1中滤网的有效流通面积满足的关系与实施例相同。
具体工作方式以及效果与实施例1一致。
替代实施例中，吸气装置包括进气管2、第一出气管6和第二出气管7，所述进气管2被设置为引入流体进入其内部，所述第一出气管6的一端与所述进气管2的内部连通、以将所述进气管2内的部分流体从所述第一出气管6导出，所述第二出气管7的一端与所述进气管2的内部连通、以将所述进气管2内的部分流体从所述第二出气管7导出，且所述进气管2的流通面积为S，所述第一出气管6的流通面积为S1，所述第二出气管7的流通面积为S2，并有S≥S1+S2(替代实施例，参见附图3)。
本公开通过将吸气装置中的进气管流通面积S、第一出气管的流通面积S1和第二出气管的流通面积为S2设置为满足关系S≥S1+S2，使得压缩机吸气装置的进气管管径与出气管满足一定的数值关系，能够有效减小吸气阻力，增大压缩机的输气量，有效提高了压缩机的能效，减小功耗。
在一些实施方式中，所述第一出气管6的另一端与压缩机的第一气缸16的吸气口连通，所述第二出气管7的另一端与压缩机的第二气缸18的吸气口连通；和/或，所述第一出气管6从所述筒体5的下端与所述筒体5的内部连通，或者所述第一出气管6从所述进气管2的下端与所述进气管2的内部连通；和/或，所述第二出气管7从所述筒体5的下端与所述筒体5的内部连通，或者所述第二出气管7从所述进气管2的下端与所述进气管2的内部连通。
这是本公开的吸气装置的进一步优选结构形式，第一出气管的另一端连通至第一气缸的吸气口能够将经过过滤和气液分离后的气体通过第一出气管导入第一气缸中进行压缩，第二出气管的另一端连通至第二气缸的吸气口能够将经过过滤和气液分离后的气体通过第二出气管导入第二气缸中进行压缩；第一出气管和第二出气管在主实施例中从筒体的下端向上插入筒体中，替代实施例中第一出气管和第二出气管从进气管的下端插入其内部，形成有效的连通。
在一些实施方式中，当所述第一出气管6从所述筒体5的下端与所述筒体5的内部连通，所述第二出气管7从所述筒体5的下端与所述筒体5的内部连通时：
所述第一出气管6伸入所述筒体5内部第一高度，所述第二出气管7伸入所述筒体5内部第二高度，且所述第一出气管6伸入所述筒体5内部的上端面 与所述第二出气管7伸入所述筒体5内部的上端面之间存在高度差H，且所述H>0。
本公开还通过将吸气装置的两个及以上的出气管设置为不等高出气管结构，能够有效降低压缩机两个气缸的吸气脉动干扰，使压缩机吸气更顺畅，降低了压缩机的功耗，提高了压缩机的能效。吸气装置4的出气管的不等高结构设计降低了压缩机两个气缸的吸气脉动干扰，使压缩机吸气更顺畅，压缩机的功耗降低。转子压缩机吸气装置的进气管管径与出气管满足上述的数值关系，可有效减小吸气阻力，增大压缩机的输气量，使得压缩机能效大幅提升。
在一些实施方式中，所述第一出气管6伸出所述筒体5外部的下端面与所述第二出气管7伸出所述筒体5外部的下端面之间存在高度差H1，且有所述H1＝H。满足H＝H1，满足此关系后第一出气管6和第二出气管7的上端可以避免吸气相互干扰，压缩机运行时吸气装置4的振动加速度较常规分液器拥有大幅降低(如图2)，首先是保证了第一出气管和第二出气管的入口存在高度差，避免两管的进气口吸气互相干扰在筒体空间内产生较大的吸气脉动，其次保证两个管长相等，使得两吸气管流路长度相当等，避免长短差引起额外吸气脉动。
在一些实施方式中，当所述第一出气管6从所述筒体5的下端与所述筒体5的内部连通，所述第二出气管7从所述筒体5的下端与所述筒体5的内部连通时：
所述第一出气管6的上端面高度高于所述第二出气管7的上端面高度，且有第一出气管的上端面与进气管2的下端面距离为H2，所述筒体5的总高度为H3，满足1/5H3≤H2≤1/3H3。限制H2的尺寸的下限是为了避免进气管2进入筒体的气体直接冲进第一出气管6，降低吸气脉动；上限的目的是为了防止第一出气管6和第二出气管7的长度过短，而避免进气量的减小。
在一些实施方式中，还包括过滤装置1，所述过滤装置1设置于所述筒体5外部或所述进气管2的外部、且与所述进气管2连通，且所述过滤装置1的流通面积为S4，并有S4≥S。通过将过滤装置设置于气分装置的外部并且将过滤装置的流通面积做得比进气管流通面积大，能够有效地增大过滤装置的过滤面积和流通面积，与常规内置滤网和滤网支架分液器相比有效降低了转子压缩机吸气装置内的气流阻力，提高了压缩机的能效。见图4，滤网是网状结构，在过滤杂质的同时也阻碍了气体流动，因此需要流通面积做大，尽量减小气体流动阻力(S4指滤网所有小孔的面积之和)。
在一些实施方式中，所述过滤装置1的进口端还连通设置有进管1a，所述进管1a的流通面积为S3，且有S≥S3。将进管1a的流通面积为S3设置为S≥S3能够有效减小分液器的吸气阻力。过滤装置1的入口与系统冷媒出口(蒸发器的出口)通过管道连通，该部分管道有效流通面积为S3；过滤装置1的出口与进气管2的上端通过管道连通，该部分管道的有效流通面积为S，满足关系S≥S3；过滤装置1中滤网的有效流通面积为S4，满足S4≥S。
为了防止压缩机吸入杂质颗粒同时又要避免增大压缩机的吸气阻力，在吸气装置4的进气管2与蒸发器的出口之间设置一个过滤装置1，在过滤装置1的入口与系统冷媒出口(蒸发器的出口)通过管道连通，该部分管道有效流通面积为S3；过滤装置1的出口(下端)与进气管2的上端通过管道连通，该部分管道的有效流通面积与进气管的流通面积相等，也为S，满足关系S≥S3；为尽量的降低压缩机的吸气阻力，过滤装置1中滤网的有效流通面积(滤网上小孔的面积之和)为S4，满足S4≥S；由于过滤装置1设置在吸气装置4的外部，过滤装置1的筒体5可以紧凑化设计，相对减小了压缩机的外观尺寸，使得压缩机在空调系统匹配时压缩机更容易实现装配。
在一些实施方式中，所述第一出气管6上开设有用于回油的第一回油孔81；和/或，所述第二出气管7上开设有用于回油的第二回油孔82；和/或，S1＝S2。第一出气管6和第二出气管7靠近下端盖9的上部分别设置有回油孔，在吸气装置4的内部油气分离后的冷冻油通过孔缓慢回到第一气缸16和第二气缸18内。
在一些实施方式中，当包括第一回油孔81和第二回油孔82时：所述第一回油孔81为毛细孔，所述第二回油孔82为毛细孔；和/或，当包括筒体5、第一回油孔81和第二回油孔82时，所述第一回油孔81开设于所述第一出气管6上相对靠近所述筒体5的下端盖且高于所述下端盖的位置；所述第二回油孔82开设于所述第二出气管7上相对靠近所述筒体5的下端盖且高于所述下端盖的位置。
这是本公开的回油孔的优选结构形式，通过毛细孔能够使得油缓慢地回到气缸中，有利于回油。
本公开还提供一种压缩组件(优选转子压缩机)，其包括前任一项所述的吸气装置4，还包括压缩机，所述压缩机包括第一气缸16和第二气缸18，且所述第一出气管6与所述第一气缸16的进气口连通，所述第二出气管7与所述第二气缸18的进气口连通。本公开不仅适用于双缸压缩机，还可以用于三 缸缸压缩机、多级压缩机、立式和卧式等压缩机。
本公开还提供一种空调器，其包括前述的压缩组件。
本公开通过将吸气装置中的进气管流通面积S、第一出气管的流通面积S1和第二出气管的流通面积为S2设置为满足关系S≥S1+S2，使得压缩机吸气装置的进气管管径与出气管满足一定的数值关系，能够有效减小吸气阻力，增大压缩机的输气量，有效提高了压缩机的能效，减小功耗；本公开还通过将吸气装置的两个及以上的出气管设置为不等高出气管结构，能够有效降低压缩机两个气缸的吸气脉动干扰，使压缩机吸气更顺畅，降低了压缩机的功耗，提高了压缩机的能效；本公开还通过将过滤装置设置于气分装置的外部并且将过滤装置的流通面积做得比进气管流通面积大，能够有效地增大过滤装置的过滤面积和流通面积，与常规内置滤网和滤网支架分液器相比有效降低了转子压缩机吸气装置内的气流阻力，提高了压缩机的能效。本公开的吸气装置结构紧凑，相对减小了压缩机的外观尺寸，使得压缩机在空调系统匹配时压缩机更容易实现装配。本公开的结构还具有加工简单、实用性强、成本低、便于推广等优点。
以上仅为本公开的较佳实施例而已，并不用以限制本公开，凡在本公开的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本公开的保护范围之内。以上仅是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开技术原理的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本公开的保护范围。
