技术领域Technical Field
本发明涉及压缩机领域，具体而言涉及一种涡旋结构和一种压缩机。The invention relates to the field of compressors, and in particular to a scroll structure and a compressor.
背景技术Background Art
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’。In the related art, as shown in FIG. 1 , a scroll compressor 100 ′ includes a casing 300 ′, a discharge cover 400 ′, a frame 500 ′, a static scroll 220 ′, a dynamic scroll 210 ′, a back pressure plate 230 ′, and a floating plate 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。The static scroll 220' and the dynamic scroll 210' together form a suction chamber, an intermediate pressure chamber and a discharge chamber, and the dynamic scroll 210' can move relative to the static scroll 220'.
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’。In order to ensure the fit between the static scroll 220’ and the dynamic scroll 210’, a back pressure plate 230’ is arranged on the top of the static scroll 220’, and a floating plate 240’ is arranged on the back pressure plate 230’. The back pressure plate 230’ and the floating plate 240’ form a back pressure chamber 282’, and the back pressure chamber 282’ is connected to the intermediate pressure chamber. Therefore, when the static scroll 220’ and the dynamic scroll 210’ are performing compression operation, the pressure in the intermediate pressure chamber will pressurize the back pressure chamber 282’, thereby pushing the floating plate 240’. The floating plate 240’ floats up and abuts against the discharge cover 400’ of the compressor 100’, thereby pressing the static scroll 220’ toward the dynamic scroll 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。However, in such a structure, the back pressure plate 230' is arranged on the top of the static scroll 220', so the airtightness of the outer position connected between the back pressure plate 230' and the static scroll 220' is poor, and it is necessary to add a sealing ring 920'. Moreover, if the connection point between the back pressure plate 230' and the static scroll 220' is far away, the sealing performance of the sealing ring 920' will also be affected, which will lead to poor airtightness between the discharge chamber and the suction chamber, thereby affecting the performance of the compressor 100'.
发明内容Summary of the invention
本发明旨在至少解决现有技术中存在的技术问题之一。The present invention aims to solve at least one of the technical problems existing in the prior art.
为此，本发明第一方面提供了一种涡旋结构。To this end, a first aspect of the present invention provides a vortex structure.
本发明第二方面提供了一种压缩机。A second aspect of the present invention provides a compressor.
有鉴于此，根据本发明的第一方面实施例，本发明提出了一种涡旋结构，包括：第一涡旋盘；第二涡旋盘，与第一涡旋盘相配合，第一涡旋盘和第二涡旋盘可相对运动，第二涡旋盘背离第一涡旋盘的一端设有凹槽，第二涡旋盘设置有第一通孔；背压板，设于凹槽内，背压板与凹槽的侧壁之间具有间隙；浮板，可活动地设置在背压板上，浮板覆设于间隙上，第二涡旋盘、背压板和浮板之间形成第一腔室，第一通孔与第一腔室连通。In view of this, according to the first aspect embodiment of the present invention, the present invention proposes a vortex structure, including: a first scroll plate; a second scroll plate, which cooperates with the first scroll plate, the first scroll plate and the second scroll plate can move relative to each other, and the end of the second scroll plate away from the first scroll plate is provided with a groove, and the second scroll plate is provided with a first through hole; a back pressure plate, which is arranged in the groove, and there is a gap between the back pressure plate and the side wall of the groove; a floating plate, which can be movably arranged on the back pressure plate, and the floating plate covers the gap, and a first chamber is formed between the second scroll plate, the back pressure plate and the floating plate, and the first through hole is connected to the first chamber.
本发明提出的涡旋结构，第一涡旋盘和第二涡旋盘形成了吸入室、中间压力室和排放室，进而在第一涡旋盘和第二涡旋盘执行压缩作业时，由吸入室吸入冷媒，经中间压力室压缩后，排入排放室，从而完成压缩作业。The scroll structure proposed in the present invention comprises a first scroll plate and a second scroll plate which form a suction chamber, an intermediate pressure chamber and a discharge chamber. When the first scroll plate and the second scroll plate perform a compression operation, the refrigerant is sucked into the suction chamber, compressed in the intermediate pressure chamber, and then discharged into the discharge chamber, thereby completing the compression operation.
进一步地，通过在第二涡旋盘背离第一涡旋盘的一端设置凹槽，在凹槽内设置背压板，并且，背压板与凹槽的侧壁之间具有间隙，在间隙上盖设浮板。进而第二涡旋盘、背压板和浮板之间形成第一腔室，第二涡旋盘上还设置有第一通孔，第一通孔连通第一腔室。具体地，第一通孔连通第一腔室和中间压力腔。进而在第一涡旋盘和第二涡旋盘执行压缩作业时，中间压力腔内的冷媒为第一腔室提供压力，进而使得浮板移动，进而在浮板被限制时，第一腔室内的压力迫使第二涡旋盘向第一涡旋盘移动，即将第二涡旋盘压向第一涡旋盘，进而可以增强第一涡旋盘和第二涡旋盘之间的密闭性，防止冷媒泄漏，提升压缩效率。Furthermore, a groove is provided at one end of the second scroll away from the first scroll, a back pressure plate is provided in the groove, and a gap is provided between the back pressure plate and the side wall of the groove, and a floating plate is provided on the gap. A first chamber is formed between the second scroll, the back pressure plate and the floating plate, and a first through hole is also provided on the second scroll, and the first through hole is connected to the first chamber. Specifically, the first through hole is connected to the first chamber and the intermediate pressure chamber. When the first scroll and the second scroll perform compression operations, the refrigerant in the intermediate pressure chamber provides pressure for the first chamber, thereby causing the floating plate to move. When the floating plate is restricted, the pressure in the first chamber forces the second scroll to move toward the first scroll, that is, presses the second scroll toward the first scroll, thereby enhancing the airtightness between the first scroll and the second scroll, preventing refrigerant leakage, and improving compression efficiency.
并且，由于背压板是设置第二涡旋盘的凹槽内的，因此，整个第二涡旋盘的外壁是一体的，进而增强了排放室和吸入室之间的密闭性，进一步提升了压缩效率。Furthermore, since the back pressure plate is disposed in the groove of the second scroll, the outer wall of the entire second scroll is integrated, thereby enhancing the airtightness between the discharge chamber and the suction chamber, and further improving the compression efficiency.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
下面参照图2至图5来描述根据本发明一些实施例提供的涡旋结构200和压缩机100。The scroll structure 200 and the compressor 100 provided in some embodiments of the present invention are described below with reference to FIGS. 2 to 5 .
实施例1：Embodiment 1:
如图2和图3所示，根据本发明的第一方面实施例，本发明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。As shown in Fig. 2 and Fig. 3, according to the first aspect of the present invention, one embodiment of the present invention provides a scroll structure 200 for a compressor 100, the scroll structure 200 comprising: a first scroll plate 210 and a second scroll plate 220 cooperating with the first scroll plate 210. The first scroll plate 210 and the second scroll plate 220 can cooperate to form: a suction chamber 286, an intermediate pressure chamber 288 and a discharge chamber 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。Specifically, the first scroll 210 is dynamic and the second scroll 220 is static. When the first scroll 210 moves around the rotating shaft 910, the refrigerant is sucked in through the suction chamber 286, and the refrigerant is compressed through the intermediate pressure chamber 288. Finally, the compressed refrigerant is discharged into the discharge chamber 290 so that the refrigerant can be discharged, thereby completing a compression operation.
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。Furthermore, the scroll structure 200 further includes: a back pressure plate 230 and a floating plate 240. A groove 226 is provided at one end of the second scroll plate 220 away from the first scroll plate 210, the inner side wall of the groove 226 is a first wall 2262, the back pressure plate 230 is provided in the groove 226, the outer side wall of the back pressure plate 230 is a second wall 2342, the first wall 2262 and the second wall 2342 are opposite to each other and have a gap, and the two sides of the floating plate 240 are movably connected to the first wall 2262 and the second wall 2342, respectively, and then the first chamber 282 is formed under the enclosure of the second scroll plate 220, the back pressure plate 230 and the floating plate 240. In addition, a first through hole 2222 is also provided on the second scroll plate 220, and the first through hole 2222 communicates the first chamber 282 and the intermediate pressure chamber 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。Specifically, when the first scroll 210 and the second scroll 220 perform compression operations, the refrigerant in the intermediate pressure chamber 288 is pressurized and pressurizes the first chamber 282 through the first through hole 2222, thereby causing the floating plate 240 to move outward. On this basis, the movement of the floating plate 240 can be restricted, so that the pressure in the first chamber 282 will act on the second scroll 220, thereby pressing the second scroll 220 toward the first scroll 210, thereby ensuring the close connection between the first scroll 210 and the second scroll 220, that is, ensuring the independence of the suction chamber 286, the intermediate pressure chamber 288 and the discharge chamber 290, thereby improving the compression effect and compression efficiency of the scroll structure 200.
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，即本发明提供的涡旋结构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，本发明提供的涡旋结构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。Furthermore, since the back pressure plate 230 is disposed in the groove 226 of the second scroll disk 220, the gaps of the first chamber 282 include the gap between the floating plate 240 and the second scroll disk 220, the gap between the floating plate 240 and the back pressure plate 230, and a gap between the back pressure plate 230 and the second scroll disk 220, that is, the first chamber 282 in the scroll structure 200 provided by the present invention has only three gaps. In the related art, the back pressure chamber has two gaps between the back pressure plate 230 and the second scroll disk 220, in addition to the gap between the floating plate 240 and the second scroll disk 220 and the gap between the floating plate 240 and the back pressure plate 230. Relatively speaking, the first chamber 282 in the scroll structure 200 provided by the present invention reduces the gaps, thereby simplifying the sealing structure for the first chamber 282, reducing the production cost, and improving the sealing effect, thereby ensuring the compression efficiency of the scroll structure 200.
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。Furthermore, the shape, structure and number of the first chamber 282 can be arbitrarily set as needed. For example, an annular first chamber 282 is set, that is, the first wall 2262 of the second scroll 220 and the second wall 2342 of the back pressure plate 230 are completely separated; or a semi-annular first chamber 282 is set, that is, the first wall 2262 of the second scroll 220 and the second wall 2342 of the back pressure plate 230 are partially separated; or a plurality of first chambers 282 are set, that is, the first wall 2262 of the second scroll 220 and the second wall 2342 of the back pressure plate 230 are partially in contact.
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，在本发明的其他实施例中也可以设置一个、二个、四个、五个等。The shape, structure and number of the first through holes 2222 can also be set as required. For example, three first through holes 2222 are evenly arranged on the second scroll plate 220 to ensure uniform force on the floating plate 240. Of course, one, two, four, five, etc., can also be arranged in other embodiments of the present invention.
具体地，一个第一腔室282至少与一个第一通孔2222相连通。Specifically, one first chamber 282 is communicated with at least one first through hole 2222 .

The second disk body 222 is further provided with a second through hole 2224. Specifically, the second volute 224 is adapted to the first scroll 210 and can perform compression operations. More specifically, the first volute 214 is adapted to the second volute 224.
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。In this embodiment, the groove 226 and the second vortex tooth 224 are respectively located at opposite ends of the second disk body 222, so that the first chamber 282 in the groove 226 is subjected to force, forcing the second disk body 222 to move toward the first disk body 212. The movement mode has a short stroke, thereby ensuring the sealing effect of the first scroll plate 210 and the second scroll plate 220.
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。Furthermore, the refrigerant compressed by the first scroll 210 and the second scroll 220 is discharged through the second through hole 2224 on the second disk body 222, that is, the refrigerant in the discharge chamber 290 is discharged. Specifically, when used in the compressor 100, the second through hole 2224 is connected to the discharge space of the compressor 100, and the refrigerant can be discharged from the compressor 100 through the discharge space.
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。Specifically, since the position of the first chamber 282 and the position of the intermediate pressure chamber 288 may not match, when opening the first through hole 2222, a channel can be first opened horizontally in the second disk body 222, and then the channels are drilled at the positions of the first chamber 282 and the intermediate pressure chamber 288 respectively, and then the outlets of the channels are closed to form a bent first through hole 2222. This method of forming the first through hole 2222 is simple and reliable.

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。As shown in FIG2 , on the basis of any one of Embodiments 1 to 8, further, the back pressure plate 230 includes a back pressure body 232 and a protrusion 234 disposed on one side of the back pressure body 232, and a third through hole 2322 is disposed on the back pressure body 232, and the third through hole 2322 is communicated with the second through hole 2224. The second wall 2342 is located on the outer peripheral side of the protrusion 234, and the inner peripheral side of the protrusion 234 surrounds the third through hole 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。In this embodiment, the protrusion 234 is annular in structure, and the first wall 2262 on the outside of the protrusion 234 is used to guide the floating plate 240 to facilitate the movement of the floating plate 240. At the same time, the third through hole 2322 on the inside of the protrusion 234 guides the refrigerant discharged from the second through hole 2224 so that it can flow to the discharge space of the compressor 100, thereby facilitating the discharge of the refrigerant.
实施例10：Embodiment 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。As shown in FIG2 , on the basis of any one of Embodiments 1 to 9, further, a second chamber 284 and a fifth through hole connecting the second chamber 284 and the third through hole 2322 are further provided on the side of the back pressure plate 230 opposite to the second scroll plate 220, a fourth through hole 2226 connecting the second chamber 284 is further provided on the second scroll plate 220, and a first check valve 270 blocked on the fourth through hole 2226 is further provided in the second chamber 284. Specifically, the fourth through hole 2226 connects the second chamber 284 and the intermediate pressure chamber 288, and the fifth through hole connects the second chamber 284 and the discharge space of the compressor 100.
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。In this embodiment, a secondary refrigerant discharge flow channel is provided on the scroll structure 200, that is, the refrigerant compressed by the first scroll 210 and the second scroll 220 is not only discharged through the discharge chamber 290 and the second through hole 2224, but a part of the refrigerant also passes through the intermediate pressure chamber 288 and the fourth through hole 2226, enters the second chamber 284, and then flows into the third through hole 2322 through the fifth through hole for discharge. Furthermore, since the refrigerant in the discharge chamber 290 may not be completely discharged, or the refrigerant in the discharge chamber 290 may not be discharged, the refrigerant in the intermediate pressure chamber 288 can be discharged through the path of the fourth through hole 2226, the second chamber 284 and the fifth through hole, so that the scroll structure 200 can adapt to different working conditions, thereby improving the performance and efficiency of the scroll structure 200.
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。Specifically, the first check valve 270 may be a pressure-opening valve, which opens when the pressure in the intermediate pressure chamber 288 reaches a preset threshold value to ensure the compression effect on the refrigerant.
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。Since the structure includes the second chamber 284, in order to ensure the sealing of the entire structure, the fourth through hole 2226 needs to be arranged inside the groove 226, and the second chamber 284 and the third through hole 2322 are connected through the fifth through hole on the back pressure plate 230. In addition, on the basis of the third through hole 2322 extending the second through hole 2224, the sealing of the entire vortex structure 200 can be further ensured.

The discharge cover 400 divides the interior of the casing 300 into a suction space and a discharge space, the frame 500 is located in the suction space, and the scroll structure 200 is disposed on the frame 500. Specifically, the second scroll 220 can be fixed to the frame 500 by screws, and the first scroll 210 is overlapped on the frame 500, so that the first scroll 210 can move relative to the second scroll 220.
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。The second check valve 600 is disposed at the second through hole 2224 of the second scroll plate 220 , so as to prevent the refrigerant in the discharge space from flowing back after the refrigerant is discharged from the scroll structure 200 .
本发明提供的压缩机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。The compressor 100 provided by the present invention includes the scroll structure 200 provided by any of the above embodiments, and therefore has all the beneficial effects of the scroll structure 200 provided by any of the above embodiments, which are described one by one in this step.
实施例15：Embodiment 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。As shown in FIG5 , on the basis of Embodiment 14, the compressor 100 further includes a motor structure 900 , and the motor structure 900 has a rotating shaft 910 . The rotating shaft 910 is connected to the connecting portion 216 of the first scroll 210 .
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。The frame 500 includes a first frame 510 and a second frame 520 , the vortex structure 200 is disposed on the first frame 510 , and the motor structure 900 is disposed on the second frame 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。In this embodiment, the rotation of the rotating shaft 910 in the motor structure 900 drives the first scroll plate 210 to move around the rotating shaft 910 , thereby achieving the compression operation of the scroll structure 200 .
实施例16：Embodiment 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。As shown in FIG. 5 , on the basis of Embodiment 14 or Embodiment 15, further, the second check valve 600 is configured to be able to communicate with the second through hole 2224 and the discharge space.
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。In this embodiment, the second check valve 600 can be connected to the second through hole 2224 and the discharge space. That is, after the second through hole 2224 discharges the refrigerant to the discharge space, the residual refrigerant in the discharge space can return to between the first scroll 210 and the second scroll 220 through the second through hole 2224 under the action of pressure, thereby balancing the pressure difference between the intermediate pressure chamber 288 between the first scroll 210 and the second scroll 220 and the discharge space, and then when the first scroll 210 and the second scroll 220 complete compression again and discharge the refrigerant, the refrigerant can be smoothly discharged into the discharge space, thereby reducing the resistance to the discharge of the refrigerant and improving the compression efficiency of the scroll compressor 100.
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。Specifically, the second check valve 600 includes a slideway 610 and a check plate 620. The check plate 620 can slide in the first slideway 610 and abut against the second scroll 220, wherein when the check plate 620 abuts against the second scroll 220, the passing area between the discharge space and the second through hole 2224 is reduced, thereby limiting the amount of refrigerant discharged from the discharge space to the second through hole 2224. That is, the refrigerant in the discharge space will not flow back in large quantities, thereby ensuring the amount of refrigerant sucked into the first scroll 210 and the second scroll 220, thereby improving the compression efficiency.
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。Specifically, a plurality of discharge ports may be provided on the check plate 620 , and when the check plate 620 abuts against the second scroll 220 , some of the discharge ports are blocked by the second scroll 220 .

并且，排出管700上设置有第三止回阀710。In addition, a third check valve 710 is disposed on the discharge pipe 700 .
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。In this embodiment, the compressor 100 further includes a discharge pipe 700 and a suction pipe 800, and the discharge pipe 700 is connected to the discharge space, and then after the first scroll 210 and the second scroll 220 discharge the refrigerant to the discharge space, the refrigerant in the discharge space is discharged through the discharge pipe 700. In addition, a third check valve 710 is provided in the discharge pipe 700, and then after the refrigerant in the discharge space is discharged through the discharge pipe 700, the backflow of the refrigerant is avoided, and then the discharge space is not connected with the downstream equipment, and then the amount of refrigerant in the discharge space is guaranteed to be fixed, thereby improving the balancing effect of the pressure difference between the discharge space and the first scroll 210 and the second scroll 220.
