Description

涡旋结构和压缩机
本申请要求于2020年08月31日提交中国专利局、申请号为“202010898728.6”、申请名称为“涡旋机构和压缩机”的中国专利申请的优先权，以及，于2020年08月31日提交中国专利局、申请号为“202021861162.1”、申请名称为“涡旋结构和压缩机”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
本申请涉及压缩机领域，具体而言涉及一种涡旋结构和一种压缩机。
背景技术
相关技术中，如图1所示，涡旋式压缩机100’包括：机壳300’、排放盖400’、框架500’、静态涡旋盘220’、动态涡旋盘210’、背压板230’和浮板240’。
其中，静态涡旋盘220’和动态涡旋盘210’一起形成吸入室、中间压力室和排放室，动态涡旋盘210’相对于静态涡旋盘220’能够运动。
为了保证静态涡旋盘220’和动态涡旋盘210’贴合性，在静态涡旋盘220’的顶部设置背压板230’，并在背压板230’上设置浮板240’，背压板230’和浮板240’形成背压腔282’，背压腔282’与中间压力室连通，从而在静态涡旋盘220’和动态涡旋盘210’进行压缩作业时，中间压力室内的压力会对背压腔282’施压，从而顶动浮板240’，浮板240’上浮与压缩机100’的排放盖400’相抵，进而将静态涡旋盘220’压向动态涡旋盘210’。
但是，这样的结构，背压板230’设置在静态涡旋盘220’的顶部，所以背压板230’和静态涡旋盘220’之间连通外侧位置的密闭性较差，需要增加密封圈920’，并且，若背压板230’和静态涡旋盘220’之间的连接点距离较远，密封圈920’的密封性能也将受到影响，进而导致了排放室与吸入室之间的密闭性较差，从而影响压缩机100’的性能。

具体实施方式
为了能够更清楚地理解本申请的上述目的、特征和优点，下面结合附图和具体实施方式对本申请进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不受下面公开的具体实施例的限制。
下面参照图2至图5来描述根据本申请一些实施例提供的涡旋结构200和压缩机100。
实施例1：
如图2和图3所示，根据本申请的第一方面实施例，本申请的一个实施例提供了一种用于压缩机100的涡旋结构200，该涡旋结构200包括：第一涡旋盘210和与第一涡旋盘210配合的第二涡旋盘220。第一涡旋盘210和第二涡旋盘220可以配合以形成：吸入室286、中间压力室288和排放室290。
具体地，第一涡旋盘210作为动态，第二涡旋盘220为静态，在第一涡旋盘210绕转轴910进行运动时，通过吸入室286，吸入冷媒，再经过中间压力室288压缩冷媒，最后将压缩后的冷媒排入排放室290，以便将冷媒排出，从而完成一个压缩作业。
进一步地，涡旋结构200还包括：背压板230和浮板240。其中，在第二涡旋盘220背离第一涡旋盘210的一端设置凹槽226，凹槽226的内侧壁为第一壁2262，背压板230设置在凹槽226内，背压板230的外侧壁为第二壁2342，第一壁2262和第二壁2342相对，并具有间隙，浮板240的两侧分别于第一壁2262和第二壁2342活动连接，进而在第二涡旋盘220、背压板230和浮板240的围设下，形成第一腔室282。并且，第二涡旋盘220上还设置有第一通孔2222，第一通孔2222连通第一腔室282和中间压力室288。
具体地，在第一涡旋盘210和第二涡旋盘220进行压缩作业时，中间压力室288内的冷媒受到压力，通过第一通孔2222向第一腔室282施压， 进而促使浮板240向外运动。在此基础上，可限制浮板240的运动，这样，第一腔室282内的压力将会作用于第二涡旋盘220上，从而将第二涡旋盘220压向第一涡旋盘210，从而保证了第一涡旋盘210和第二涡旋盘220的紧密连接，即保证了吸入室286、中间压力室288和排放室290的独立性，进而提升了涡旋结构200的压缩效果和压缩效率。
并且，由于背压板230是设置在第二涡旋盘220的凹槽226内的，因此，第一腔室282的缝隙有浮板240和第二涡旋盘220之间的缝隙，浮板240和背压板230之间的缝隙，背压板230和第二涡旋盘220之间的一条缝隙，即本申请提供的涡旋结构200中第一腔室282只具有三条缝隙。而相关技术中的背压腔，除了浮板240和第二涡旋盘220之间的缝隙，浮板240和背压板230之间的缝隙之外，其背压板230和第二涡旋盘220之间具有两条缝隙，相对而言，本申请提供的涡旋结构200中第一腔室282减少了缝隙，进而简化了对于第一腔室282的密封结构，降低了生产成本，并且，提升了密封效果，进而保证了涡旋结构200的压缩效率。
进一步地，第一腔室282的形状、结构和数量可以根据需要任意设置。例如：设置一个环形的第一腔室282，即第二涡旋盘220的第一壁2262和背压板230的第二壁2342完全间隔；或者，设置一个半环形的第一腔室282，即第二涡旋盘220的第一壁2262和背压板230的第二壁2342部分间隔；或者设置多个第一腔室282，即第二涡旋盘220的第一壁2262和背压板230的第二壁2342相间隔的部分接触。
其中，第一通孔2222的形状、结构和数量也可以根据需要任意设置。例如：在第二涡旋盘220上均匀的设置三个第一通孔2222，以保证浮板240受力的均匀性。当然，在本申请的其他实施例中也可以设置一个、二个、四个、五个等。
具体地，一个第一腔室282至少与一个第一通孔2222相连通。
进一步地，第一壁2262和/或第二壁2342呈环形结构。

具体地，第一密封件250为密封圈。
如图2所示，可以在浮板240上设置安装槽，第一密封件250的嵌入安装槽内，另一部分可与第二涡旋盘220相抵，使得第一密封件250被挤压，实现浮板240和第二涡旋盘220之间的密封。具体地，第一密封件250与第二涡旋盘220的第一壁2262相抵。
当然，也可以在第二涡旋盘220上设置安装槽，第一密封件250的嵌入安装槽内，另一部分可与浮板240相抵，使得第一密封件250被挤压，实现浮板240和第二涡旋盘220之间的密封。具体地，安装槽设置在第二涡旋盘220的第一壁2262上。
实施例3：
如图2所示，在实施例1或实施例2的基础上，进一步地，涡旋机构还包括：设置在背压板230和浮板240之间的第二密封件260。其中，第二密封件260设置在浮板240和第二壁2342之间。
具体地，第二密封件260为密封圈。
如图2所示，可以在浮板240上设置安装槽，第二密封件260的嵌入安装槽内，另一部分可与背压板230相抵，使得第二密封件260被挤压，实现浮板240和背压板230之间的密封。具体地，第二密封件260与背压板230的第二壁2342相抵。
当然，也可以在背压板230上设置安装槽，第二密封件260的嵌入安装槽内，另一部分可与浮板240相抵，使得第二密封件260被挤压，实现浮板240和背压板230之间的密封。具体地，安装槽设置在背压板230的第二壁2342上。
实施例4：
在实施例1至实施例3中任一者的基础上，进一步地，第二涡旋盘220上的凹槽226设置为台阶槽，凹槽226的第一台阶面朝向浮板240。具体地，第一壁2262上具有第一台阶面。
即可以采用凹槽226内的第一台阶面支撑浮板240，进而支撑起浮板240，在浮板240没有到第一腔室282内的压力时，也能够保持在一个特定 位置。具体地，在应用到压缩机100时，通过第一台阶面的支撑，使得浮板240和压缩机100的排放盖400相抵，即在浮板240不受力时，也与排放盖400相抵，进而在浮板240受力后，浮板240会保持不动，进而避免浮板240出现蹿动而与排放盖400发生碰撞的，降低了噪音，提升了浮板240和排放盖400的使用寿命。
实施例5：
在实施例1至实施例3中任一者的基础上，进一步地，背压板230上设置有台阶结构，背压板230上的第二台阶面朝向浮板240。具体地，第二壁2342上具有第二台阶面。
即可以采用背压板230的第二台阶面支撑浮板240，进而支撑起浮板240，在浮板240没有到第一腔室282内的压力时，也能够保持在一个特定位置。具体地，在应用到压缩机100时，通过第二台阶面的支撑，使得浮板240和压缩机100的排放盖400相抵，即在浮板240不受力时，也与排放盖400相抵，进而在浮板240受力后，浮板240会保持不动，进而避免浮板240出现蹿动而与排放盖400发生碰撞的，降低了噪音，提升了浮板240和排放盖400的使用寿命。
实施例6：
如图2和图3所示，在实施例1至实施例3中任一者的基础上，进一步地，背压板230上设置有台阶结构，背压板230上的第二台阶面朝向浮板240；第二涡旋盘220上的凹槽226设置为台阶槽，凹槽226的第一台阶面朝向浮板240。具体地，第一壁2262上具有第一台阶面，第二壁2342上具有第二台阶面。
即可以采用凹槽226内的第一台阶面和背压板230的第二台阶面共同支撑浮板240，进而支撑起浮板240，在浮板240没有到第一腔室282内的压力时，也能够保持在一个特定位置。具体地，在应用到压缩机100时，通过第二台阶面的支撑，使得浮板240和压缩机100的排放盖400相抵，即在浮板240不受力时，也与排放盖400相抵，进而在浮板240受力后，浮板240会保持不动，进而避免浮板240出现蹿动而与排放盖400发生碰撞的，降低了噪音，提升了浮板240和排放盖400的使用寿命。
进一步地，在第二涡齿224外圈的侧壁上开设有吸入口以将冷媒吸入第一涡旋盘210和第二涡旋盘220之间。
实施例7：
如图2所示，在实施例1至实施例6中任一者的基础上，进一步地，第一涡旋盘210包括第一盘体212和设置在第一盘体212一侧的第一涡齿214。其中，第一涡齿214和第二涡旋盘220相适配，可进行压缩作业。
进一步地，第一盘体212背离第一涡齿214的一端还设置有连接部216，连接部216用于与压缩机100的电机结构900的转轴910相连接，进而实现倒动第一涡旋盘210的转动，以完成压缩作业。
实施例8：
如图2所示，在实施例1至实施例7中任一者的基础上，进一步地，第二涡旋盘220包括：第二盘体222和设置在第二盘体222一端的第二涡齿224，以及设置在第二盘体222背离第二涡齿224一端的凹槽226。其中，第二盘体222上还设置有第二通孔2224。具体地，第二涡齿224和第一涡旋盘210相适配，可进行压缩作业。更具体地，第一涡齿214与第二涡齿224相适配。
在该实施例中，凹槽226与第二涡齿224分别位于第二盘体222相对的两端，进而在凹槽226内的第一腔室282受力，迫使第二盘体222向第一盘体212运动，该的运动方式行程较短，进而保证对第一涡旋盘210和第二涡旋盘220的密封效果。
并且，通过第二盘体222上的第二通孔2224，将第一涡旋盘210和第二涡旋盘220压缩的冷媒排出，即将排放室290内的冷媒排出。具体地，在用于压缩机100时，第二通孔2224和压缩机100的排放空间相连通，进而可将冷媒通过排放空间排出压缩机100。
具体地，由于第一腔室282的位置和中间压力室288的位置可能不匹配，因此，在开设第一通孔2222时，可先在第二盘体222横向开设一孔道，再分别在第一腔室282的位置和中间压力室288位置钻通孔道，再将孔道的出口处封闭，以形成折弯形的第一通孔2222，该形成第一通孔2222的方式简单可靠。
实施例9：
如图2所示，在实施例1至实施例8中任一者的基础上，进一步地，背压板230包括背压主体232和设置在背压主体232一侧的凸起234，并且，背压主体232上设置有第三通孔2322，第三通孔2322与第二通孔2224连通。其中，第二壁2342位于凸起234的外周侧，凸起234的内周侧包围第三通孔2322。
在该实施例中，凸起234呈环形结构，进而以凸起234外侧的第一壁2262为浮板240进行导向，便于浮板240的运动，同时通过凸起234内侧的第三通孔2322为第二通孔2224排出的冷媒进行导流，使得可以向压缩机100的排放空间流动，便于冷媒的排出。
实施例10：
如图2所示，在实施例1至实施例9中任一者的基础上，进一步地，背压板230与第二涡旋盘220相对的一侧还设置有第二腔室284和连通第二腔室284与第三通孔2322的第五通孔，第二涡旋盘220上还设置有连通第二腔室284的第四通孔2226，并且，在第二腔室284内还设置有封堵在第四通孔2226上的第一止回阀270。具体地，第四通孔2226连通第二腔室284和中间压力室288，第五通孔连通第二腔室284和压缩机100的排放空间。
在该实施例中，在涡旋结构200上设置一个副的冷媒排出流道，即第一涡旋盘210和第二涡旋盘220压缩作业的冷媒并不仅通过排放室290，经第二通孔2224排出，有一部分冷媒也会经过中间压力室288和第四通孔2226，进入第二腔室284，再通过第五通孔流入第三通孔2322排出。进而由于排放室290内的冷媒可能无法完全排出，或者排放室290内的冷媒可能无法排出的情况下，可以通过第四通孔2226、第二腔室284和第五通孔的路径将中间压力室288内的冷媒排出，进而使得涡旋结构200可以适应不同的工况，提高了涡旋结构200的性能和效率。
具体地，第一止回阀270可以是压力开启阀，在中间压力室288的压力到达预设阈值时开启，以保证对冷媒的压缩效果。
而由于该结构包括第二腔室284，因此，在结构上，为了保证整个结 构的密封性，第四通孔2226需要设置在凹槽226内部，并通过背压板230上的第五通孔连通第二腔室284和第三通孔2322。并且，在第三通孔2322延伸第二通孔2224的基础上，更能保证整个涡旋结构200各处的密闭性。
实施例11：
在实施例1至实施例10中任一者的基础上，进一步地，背压板230和第二涡旋盘220通过螺钉连接。
具体地，在背压板230上设置贯通孔，在第二涡旋盘220上设置有螺孔，该螺孔为盲孔，以保证第二涡旋盘220的密封性，进而通过螺钉穿过背压板230与第二涡旋盘220螺连接，实现对背压板230和第二涡旋盘220的固定。
具体地，螺钉的数量可以根据实际情况任意设置，例如：1个、2个、3个、4个、5个等。为了保证背压板230和第二涡旋盘220之间的密封性，可以设置3个以上的螺钉，以保证背压板230和第二涡旋盘220之间各处的密封性。
实施例12：
如图3所示，在实施例1至实施例11中任一者的基础上，进一步地，在背压板230和第二涡旋盘220之间设置有第三密封件920。
具体地，第三密封件920为密封圈。
可在背压板230上设置安装槽，将第三密封件920嵌入安装槽中，使得第三密封件920的另一部分与第二涡旋盘220相抵，使得第三密封件920被挤压，进而实现对背压板230和第二涡旋盘220之间的密封。
也可以在第二涡旋盘220上设置安装槽，将第三密封件920嵌入安装槽中，使得第三密封件920的另一部分与背压板230相抵，使得第三密封件920被挤压，进而实现对背压板230和第二涡旋盘220之间的密封。
还可以在第二涡旋盘220和背压板230上同时设置安装槽，将第三密封件920嵌入安装槽中，在第二涡旋盘220和背压板230相接触时，第三密封件920被挤压，进而实现，进而实现对背压板230和第二涡旋盘220之间的密封。
实施例13：
如图2所示，在实施例1至实施例12中任一者的基础上，进一步地，浮板240包括：浮板主体242和设置在浮板主体242一段的支撑部244。具体地，浮板主体242上设置有第六通孔，第六通孔套设在背压板230外。更具体地，第六通孔套设在背压板230的凸起234外。
并且，在应用于压缩机100时，通过支撑部244与压缩机100的排放盖400的相抵，实现了浮板240运动的限制。
实施例14：
如图4和图5所示，根据本申请的第二方面实施例，本申请提供了一种压缩机100，包括：机壳300、排放盖400、框架500、第二止回阀600和如上述任一实施例提供的涡旋结构200。
具体地，在机壳300内设置排放盖400和框架500，排放盖400和框架500相间隔。排放盖400将机壳300内部分成吸入空间和排放空间，框架500位于吸入空间，涡旋结构200设置在框架500上。具体地，第二涡旋盘220可通过螺钉固定在框架500，第一涡旋盘210搭接在框架500上，进而第一涡旋盘210可以相对于第二涡旋盘220运动。
第二止回阀600设置在第二涡旋盘220的第二通孔2224处，进而在涡旋结构200排出冷媒后，避免排放空间的冷媒回流。
本申请提供的压缩机100，因包括如上述任一实施例提供的涡旋结构200，因此，具有如上述任一实施例提供的涡旋结构200的全部的有益效果，在此步骤一一陈述。
实施例15：
如图5所示，在实施例14的基础上，进一步地，压缩机100还包括电机结构900，电机结构900具有转轴910。转轴910与第一涡旋盘210的连接部216相连接。
其中，框架500包括第一框架510和第二框架520，涡旋结构200设置在第一框架510，电机结构900设置在第二框架520。
在该实施例中，通过电机结构900中转轴910的转动带动第一涡旋盘210绕转轴910进行运动，从而实现涡旋结构200的压缩作业。
实施例16：
如图5所示，在实施例14或实施例15的基础上，进一步地，第二止回阀600被配置为能够连通第二通孔2224和排放空间。
在该实施例，第二止回阀600可以连通第二通孔2224和排放空间。即在第二通孔2224向排放空间排放冷媒后，排放空间内的残余冷媒可在压力的作用下，通过第二通孔2224回到第一涡旋盘210和第二涡旋盘220之间，进而平衡了第一涡旋盘210和第二涡旋盘220之间中间压力室288和排放空间之间的压差，进而在第一涡旋盘210和第二涡旋盘220再次完成压缩，并排放冷媒时，可以将冷媒顺利的排入排放空间，进而降低了冷媒的排出受到的阻力，提升了涡旋压缩机100的压缩效率。
具体地，第二止回阀600包括滑道610和止回板620。止回板620可在第一滑道610内滑动，并与第二涡旋盘220相抵，其中，在止回板620与第二涡旋盘220相抵时，排出空间和第二通孔2224之间的通过面积减小，从而限制排出空间向第二通孔2224排出的冷媒量。即排出空间内的冷媒不会大量的回流，进而保证了第一涡旋盘210和第二涡旋盘220吸入冷媒的量，进而提升了压缩效率。
具体地，可在止回板620上设置多个排出口，在止回板620与第二涡旋盘220相抵时，部分排出口被第二涡旋盘220封堵。
实施例17：
如图5所示，在实施例14至实施例16中任一者的基础上，进一步地，机壳300上还设置有排出管700和吸入管800。
并且，排出管700上设置有第三止回阀710。
在该实施例中，压缩机100还包括排出管700和吸入管800，排出管700与排放空间相连通，进而在第一涡旋盘210和第二涡旋盘220向排放空间排放冷媒后，排放空间内的冷媒由排出管700排出。并且，在排出管700设置第三止回阀710，进而在排放空间内的冷媒经由排出管700排放后，避免冷媒的回流，进而使得排放空间不与下游设备连通，进而保证了排放空间内的冷媒量固定，从而提升了排放空间与第一涡旋盘210和第二涡旋盘220之间压差的平衡效果。
实施例18：
如图4和图5所示，本申请提供的压缩机100包括：

浮板240，可移动地连接到背压板230与第二涡旋盘220，以密封腔的上部，背压板230、浮板240与第二涡旋盘220构成第一腔室282，且第一腔室282与第二涡旋盘220的中间压力室288相通；
其中，背压板230接触第二涡旋盘220的端板上表面，背压板230上延伸出凸起234，环形的凸起234，凸起234的外壁为环形的第二壁2342，形成为包围第三通孔2322，以及
浮板240和背压板230和第二涡旋盘220相连接，使得凸起234的外周面，即第二壁2342接触浮板240的内周面；
第二涡旋盘220形成凹槽226，凹槽226的内侧壁形成环形的第二壁2342，第二环形壁的内周面接触浮板240的外周面。

本申请提供了一种涡旋结构200和压缩机100。其中，压缩机100可包括机壳300、排放盖400、框架500、由框架500支撑的第一涡旋盘210以及与第一涡旋盘210一起形成吸入室286、中间压力室288和排放室290的第二涡旋盘220。压缩机100还可包括连接到第二涡旋盘220的背压板230。该压缩机100还可包括可动地连接到背压板230与第二涡旋盘220以密封第一腔室282的上部的浮板240。背压板230、浮板240与第二涡旋盘 220构成第一腔室282，且背压室与第二涡旋盘220的中间压力室288相通。
