具体实施方式
结合参见图1至6所示，根据本发明的实施例，定子组件包括定子本体1和设置在定子本体1的至少一端的定子消音器2，定子消音器2与该定子消音器2所在端的定子本体1的端面之间形成消音腔。
该定子组件包括定子本体1和定子消音器2，定子消音器2与定子本体1之间形成消音腔，通过消音腔可以有效地对壳体空腔中的气动噪音、电磁噪音以及压缩机泵体、电机运转过程中的机械噪音进行降噪，降低压缩机工作噪音，提高用户使用体验。定子消音器2可以设置在定子本体1的一端，也可以同时设置在定子本体1的两端，定子消音器2与定子本体1的端面贴合，从而形成密封的消音腔，可以起到有效的消音降噪效果。
当只在定子本体1的一端设置定子消音器2时，优选地在定子本体1的上端设置定子消音器2。
定子消音器2与定子本体1之间形成多个消音腔室，不仅可以效地对壳体空腔中的气动噪音、电磁噪音以及压缩机泵体、电机运转过程中的机械噪音进行降噪，同时可降低压缩机及空调系统的含油量，提高压缩机的性能。
在第一种定子消音器2中，定子消音器2包括端板3和设置在端板3上的凹槽4，端板3与定子本体1的端面贴合，凹槽4的开口朝向定子本体1的端面。通过在端板3上设置凹槽4，可以使得凹槽4与定子本体1的端面相配合，形成密封的消音腔。为了在周向方向上形成多个消音器，凹槽4为多个，并沿定子消音器2的周向方向排布。该端板3的形状与定子本体1的截面形状大致匹配。
凹槽4例如为径向变截面凹槽4或轴向变截面凹槽4，可以形成不同截面的消音腔，从而利用管道中声学性能突变处的声反射作用，借助管道截面突变将部分声波反射回声源方向，以达到消声目的。
当定子本体1为切边定子时，凹槽4为径向变截面凹槽4，且与定子本体1的非切边部分对应的凹槽4的径向截面大于与定子本体1的切边部分对应的凹槽4的径向截面。当定子本体1为切边定子时，如果将凹槽4均设置为与非切边部分的结构对应，会导致切边部分与定子消音器2的凹槽无法密封，降低定子消音器2的消音效果；如果将凹槽4均设置为与切边部分的结构对应，就会导致非切边部分的结构未能得到充分的利用，降低定子消音器2的消音效果。 因此，将凹槽4设置为根据切边部分和非切边部分的结构改变而改变，就可以在保证消音腔的密封效果的同时，使得消音腔的容积能够得到有效保证，使得定子消音器2的功能得到充分利用，提高定子消音器2的消音降噪效果。
凹槽4包括第一外侧壁5和第二外侧壁6，第一外侧壁5位于第二外侧壁6外侧，第一外侧壁5和第二外侧壁6沿定子消音器2的周向交替排布，第一外侧壁5的周向两侧通过两个侧板7与第二外侧壁6相连。该种凹槽4的结构根据切边定子的结构而设置，能够使得定子消音器2的结构与定子本体1的结构更加适配，更好地起到消音效果。
定子消音器2还包括排气孔8，若定子消音器2设置在定子本体1的上端，则排气孔8设置在至少一个侧板7上，从而可以避免将排气孔8直接开设在第一外侧壁5或第二外侧壁6上所导致的高压气体对壳体的直接冲击，也可以避免开设在凹槽4的底壁平面导致高压气体对漆包线、引线、过载的直接冲击。
若定子消音器2设置在定子本体1的下端，则需要将该排气孔8设置在凹槽4的底壁上，将定子消音器2与定子本体1、壳体形成的下部空腔中的气体排至定子消音器2与电机、壳体形成的上部空腔中，从而有助于聚集在凹槽4内的冷冻油流出，此时的排气孔8不仅具有排气的作用，同时还具有排油的作用。
上述的排气孔8例如为圆形、月牙形、矩形或锯齿形。
对于切边定子而言，定子消音器2还包括回油孔9，回油孔9设置在切边定子的切边部分对应的端板3边缘处，回油孔9的形状可以是圆形、月牙形或其他形状，便于冷冻油沿壳体内壁流回压缩机底部油池。
优选地，切边定子的切边部分与端板3之间形成有引气通道10，该引气通道用于将切边定子的切边与壳体形成的空腔中的气体引入到定子端面与定子消音器2所形成的消音腔室中。
在一个实施例中，切边定子的切边部分端面上设置有引气通道10，引气通道10从切边定子的外周侧延伸至凹槽4对应的端面处。该引气通道10为开设在切边部分端部的沉槽，该沉槽的长度大于定子切边部分的外边缘到第一外侧壁5的径向距离，且小于或等于定子切边部分的外边缘到凹槽4的径向方向的内周壁的径向距离，以保证可以顺利地将壳体空腔中的气体引入到消音腔中。
结合参见图5所示，在第二种定子消音器2中，为了避免在定子端面开设沉槽造成的铁损对电机效率的影响，优选地，端板3上对应切边定子的切边部分的位置处设置有凸起11，凸起11上设置有连通至凹槽4的引气通道10。该 引气通道10为开设在凸起11上的连接槽，该连接槽可以将壳体空腔中的气体引入到消音腔中。
当定子本体1为通流孔定子时，通流孔定子的通流孔与凹槽4连通。壳体空腔中的气体可以通过通流孔进入到消音腔中进行消音降噪。
定子消音器2还包括回油孔9，定子本体1还包括回油导槽，回油孔9与回油导槽对应设置。定子消音器2的上部空腔中的冷冻油可以通过回油孔9进入到回油导槽内，然后通过回油导槽流回到压缩机的底部油池中。
定子消音器2与定子本体1之间扣接固定、铆接固定或粘接固定。
定子消音器可由冷轧钢板或其他金属材料冲压而成。
根据本发明的实施例，压缩机包括定子组件，该定子组件为上述的定子组件。
定子消音器2、定子本体1和压缩机壳体之间可以过盈配合装配，从而在电机定子的至少一端形成消音腔。
本发明通过设计一定子消音器2，与定子本体1进行组合，与壳体过盈配合装配，从而形成多个消音腔室，有效地对壳体空腔中的气动噪音、电磁噪音以及压缩机泵体、电机运转过程中的机械噪音进行降噪，同时气体在壳体、定子本体1、定子消音器2形成的空腔内流动，有助于冷冻油从气体中甩出来附着在定子切边壁面、壳体内壁上，进而流回压缩机底部油池，可降低压缩机及空调系统的含油量，提高压缩机的性能。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各有利方式可以自由地组合、叠加。
以上仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。以上仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本发明的保护范围。
