而且，由于在隔板上设置多个排气通道，相较于相关技术中在背压板上设置一个排气通道而言，还能够有效降低压缩机的排气阻力，确保排气效率，提高压缩机运行过程中的稳定性和可靠性。Moreover, since a plurality of exhaust passages are provided on the separator, compared with the prior art where one exhaust passage is provided on the back pressure plate, it can also effectively reduce the exhaust resistance of the compressor, ensure exhaust efficiency, and improve compression efficiency. Stability and reliability during machine operation.
此外，通过将至少两个排气通道在靠近第二排气口的一端相互连通，还能够适应压缩机的不同工况，即无论压缩机是否打开泄压阀，均能够通过至少两个排气通道进行排气，确保压缩机稳定运行的同时，达到降低压缩机排气噪音的目的。In addition, by connecting at least two exhaust passages at the end close to the second exhaust port, it is also possible to adapt to different working conditions of the compressor, that is, no matter whether the compressor opens the pressure relief valve, at least two exhaust passages can pass through. The channel is exhausted to ensure the stable operation of the compressor and at the same time achieve the purpose of reducing the exhaust noise of the compressor.
在一种可能的技术方案中，压缩机还包括挡边，挡边设于隔板朝向压缩组件的一侧，并与压缩组件朝向隔板一侧面之间具有间隙，至少两个排气通道靠近第二排气口的一端通过间隙连通。In a possible technical solution, the compressor further includes a rib, which is arranged on the side of the partition facing the compression assembly, and has a gap with the side of the compression assembly facing the partition, and at least two exhaust passages are close to One end of the second exhaust port communicates through the gap.
在该技术方案中，限定了压缩机还包括挡边，具体而言，挡边设置在隔板朝向压缩组件的一侧，且挡边与压缩组件朝向隔板的一侧面之间具有间隙，至少两个排气通道在靠近第二排气口的一端，通过该间隙相互连通。In this technical solution, it is defined that the compressor further includes a rib, specifically, the rib is arranged on the side of the partition facing the compression assembly, and there is a gap between the rib and the side of the compression assembly facing the partition, at least The two exhaust passages communicate with each other through the gap at one end close to the second exhaust port.
通过将至少两个排气通道在靠近第二排气口的一端相互连通，能够适应压缩机的不同工况，即无论压缩机是否打开泄压阀，均能够通过至少两个排气通道进行排气，确保压缩机稳定运行的同时，达到降低压缩机排气噪音的目的。By connecting at least two exhaust channels at the end close to the second exhaust port, it is possible to adapt to different working conditions of the compressor, that is, no matter whether the compressor opens the pressure relief valve, it can be exhausted through at least two exhaust channels. To ensure the stable operation of the compressor and reduce the exhaust noise of the compressor.
此外，通过设置挡边，减小至少两个排气通道之间相互连通的通流截面积，从而使得气流在经过间隙流出后，能够发生截面突变，改变气流的流动路径，能够进一步降低压缩机排气时产生的气流噪音，进而降低压缩机的整体噪音。In addition, by setting the ribs, the flow cross-sectional area of at least two exhaust passages that communicate with each other is reduced, so that after the airflow flows out through the gap, a sudden change in cross-section can occur, changing the flow path of the airflow, and further reducing the pressure of the compressor. Airflow noise generated during exhaust, thereby reducing the overall noise of the compressor.
举例地，多个排气通道包括第一排气通道和第二排气通道，其中，第一排气通道和第二排气通道通过间隙连通。压缩机排气时，压缩腔内的高温高压气体经第二排气口排出，部分高温高压气体通过第一排气通道排出，部分高温高压气体经间隙流至第二排气通道，并通过第二排气通道排出。For example, the plurality of exhaust channels include a first exhaust channel and a second exhaust channel, wherein the first exhaust channel and the second exhaust channel communicate through a gap. When the compressor is exhausted, the high-temperature and high-pressure gas in the compression chamber is discharged through the second exhaust port, part of the high-temperature and high-pressure gas is discharged through the first exhaust channel, and part of the high-temperature and high-pressure gas flows through the gap to the second exhaust channel and passes through the second exhaust channel. Two exhaust channels are discharged.
在一种可能的技术方案中，间隙的轴向高度h满足0mm＜h≤5mm。In a possible technical solution, the axial height h of the gap satisfies 0mm<h≤5mm.
在该技术方案中，限定了挡边与压缩组件朝向隔板的一侧面之间间隙的轴向高度的取值范围。从而能够在适应压缩机不同工况，降低压缩机排气阻力的同时，进一步降低压缩机的排气噪音，进而降低压缩机的整体噪音，提升具有该压缩机的空调器的产品品质，进而提升用户的使用体验。In this technical solution, the value range of the axial height of the gap between the rib and the side of the compression assembly facing the partition is limited. Therefore, while adapting to different working conditions of the compressor and reducing the exhaust resistance of the compressor, the exhaust noise of the compressor can be further reduced, thereby reducing the overall noise of the compressor, improving the product quality of the air conditioner with this compressor, and further improving User experience.
能够理解的是，若该间隙的轴向高度较大，即大于5mm，也就是说，至少两个排气通道之间相互连通的通流截面积较大。则虽然可以保证至少两个排气通道之间的相互连通，但会减小压缩机运行过程中的消声量，导致消声效果降低。It can be understood that if the axial height of the gap is relatively large, ie greater than 5 mm, that is to say, the cross-sectional area of the communication between at least two exhaust passages is relatively large. Although the communication between at least two exhaust passages can be ensured, the amount of noise reduction during the operation of the compressor will be reduced, resulting in a reduction in the noise reduction effect.

The gas port flows back into the compression chamber, which causes the compressor to reverse.
通过将第一排气通道与第二排气通道沿径向，且由内而外间隔排布，能够防止止回阀在向远离或靠近第二排气口的过程中对排气通道进行遮挡，进而导致排气阻力增加的问题，确保压缩机的稳定运行。By arranging the first exhaust passage and the second exhaust passage radially and spaced from the inside to the outside, it is possible to prevent the check valve from blocking the exhaust passage in the process of moving away from or approaching the second exhaust port , which in turn leads to the problem of increased exhaust resistance, ensuring the stable operation of the compressor.
在一种可能的技术方案中，第一排气通道包括多个第一排气子通道，多个第一排气子通道沿周向间隔设置；和/或第二排气通道包括多个第二排气子通道，多个第二排气子通道沿周向间隔设置。In a possible technical solution, the first exhaust channel includes a plurality of first exhaust sub-channels, and the plurality of first exhaust sub-channels are arranged at intervals along the circumferential direction; and/or the second exhaust channel includes a plurality of first exhaust sub-channels. Two exhaust sub-channels, a plurality of second exhaust sub-channels are arranged at intervals along the circumferential direction.

在实际应用中，每个第一排气子通道的横截面形状可为U形，第一排气子通道的数量大于或等于2个，具体可以根据实际需要进行设置。In practical applications, the cross-sectional shape of each first exhaust sub-channel may be U-shaped, and the number of first exhaust sub-channels is greater than or equal to two, which may be set according to actual needs.
第二排气通道包括多个第二排气子通道，且多个第二排气子通道沿周向间隔排布，即在压缩机排气时，对气体进行分流，从而能够在不提高排气阻力的同时，降低压缩机排气过程中的排气脉动和排气噪音，进而降低压缩机的整体噪音。The second exhaust channel includes a plurality of second exhaust sub-channels, and the plurality of second exhaust sub-channels are arranged at intervals in the circumferential direction, that is, when the compressor exhausts, the gas is divided, so that the gas can be divided without increasing the discharge rate. While reducing the air resistance, it reduces the exhaust pulsation and exhaust noise during the compressor exhaust process, thereby reducing the overall noise of the compressor.
在实际应用中，每个第二排气子通道的横截面形状可为圆形，第二排气子通道的数量大于或等于2个，具体可以根据实际需要进行设置。In practical applications, the cross-sectional shape of each second exhaust sub-channel may be circular, and the number of second exhaust sub-channels is greater than or equal to two, which may be set according to actual needs.
沿径向，多个第二排气子通道位于多个第一排气子通道的外侧。从而能够防止止回阀在向远离或靠近第二排气口的过程中对排气通道进行遮挡，进而导致排气阻力增加的问题，确保压缩机的稳定运行。Along the radial direction, the plurality of second exhaust sub-channels are located outside the plurality of first exhaust sub-channels. Therefore, it is possible to prevent the check valve from blocking the exhaust passage in the process of moving away from or approaching the second exhaust port, thereby causing the problem of increased exhaust resistance, and ensuring the stable operation of the compressor.
在一种可能的技术方案中，第一排气通道的通流截面积A与第二排气通道的通流截面积B，满足0.5≤A/B≤2。In a possible technical solution, the flow cross-sectional area A of the first exhaust channel and the flow cross-sectional area B of the second exhaust channel satisfy 0.5≦A/B≦2.
在该技术方案中，第一排气通道与第二排气通道的通流截面的比值在0.5至2之间，从而能够在降低压缩机排气噪音的同时，不影响压缩机的排气效率，即能够在不增加排气阻力的前提下，大幅降低压缩机排气过程中的气流噪音，进而降低压缩机的整体噪音。In this technical solution, the ratio of the flow cross section of the first exhaust passage to the second exhaust passage is between 0.5 and 2, so as to reduce the exhaust noise of the compressor without affecting the exhaust efficiency of the compressor , that is, it can greatly reduce the airflow noise during the compressor exhaust process without increasing the exhaust resistance, thereby reducing the overall noise of the compressor.
在一种可能的技术方案中，压缩机还包括止回阀，止回阀设于隔板，并能够相对于隔板运动，止回阀用于在压缩机停止工作时，位于第二排气口处。In a possible technical solution, the compressor further includes a check valve, which is arranged on the partition and can move relative to the partition. Mouth.
在该技术方案中，限定了压缩机还包括止回阀，具体而言，止回阀设置在隔板上，且止回阀能够相对于隔板运动，具体地，止回阀能够相对于隔板向靠近或远离第二排气口运动。In this technical solution, it is defined that the compressor further includes a check valve. Specifically, the check valve is arranged on the partition plate, and the check valve can move relative to the partition plate. Specifically, the check valve can move relative to the partition plate. The plate moves toward or away from the second exhaust port.
止回阀能够在压缩机停机时，位于第二排气口处。能够理解的是，压缩机排气时，高压气体会推动止回阀向远离第二排气口的一侧运动，以降低排气阻力；当停机时，流出排气通道的部分高压气体会发生回流，高压气流会推动止回阀，同时，由于止回阀本身重力的因素，使得止回阀向靠近第二排气口的一侧运动，以部分封盖第二排气口，减小高压气体经第二排气口回流至压缩腔内，进而导致压缩机停机后反转的问题。The check valve can be located at the second discharge port when the compressor is shut down. It can be understood that when the compressor is exhausted, the high-pressure gas will push the check valve to move to the side away from the second exhaust port to reduce the exhaust resistance; when the compressor stops, part of the high-pressure gas flowing out of the exhaust channel will Backflow, the high-pressure airflow will push the check valve, and at the same time, due to the gravity of the check valve itself, the check valve will move to the side close to the second exhaust port to partially cover the second exhaust port and reduce the high pressure. The gas flows back into the compression chamber through the second exhaust port, which causes the problem of reverse rotation after the compressor stops.
在一种可能的技术方案中，隔板朝向压缩组件的一侧设有安装腔，安装腔与至少一个排气通道和第二排气口连通，止回阀的至少一部分设于安装腔内，并能够在安装腔内轴向运动，以靠近或远离第二排气口。In a possible technical solution, an installation cavity is provided on the side of the partition facing the compression assembly, the installation cavity communicates with at least one exhaust passage and the second exhaust port, at least a part of the check valve is arranged in the installation cavity, And it can move axially in the installation cavity to get close to or away from the second exhaust port.
在该技术方案中，限定了隔板还设有安装腔，安装腔靠近压缩组件的一侧设置。具体地，安装腔与第二排气口和至少一个排气通道连通。止回阀设置在安装腔内，且能够在安装腔内进行轴向运动，以向靠近或远离第二排气口的方向运动。In this technical solution, the partition plate is defined and an installation cavity is provided, and the installation cavity is arranged on one side close to the compression assembly. Specifically, the installation cavity communicates with the second exhaust port and at least one exhaust channel. The check valve is arranged in the installation cavity, and can move axially in the installation cavity to move toward or away from the second exhaust port.
具体地，压缩机排气时，高压气体会推动止回阀向远离第二排气口的一侧运动，以降低排气阻力，高压气体通过止回阀的外壁与隔板位于安装腔的内壁之间，并通过至少一个排气通道排出。Specifically, when the compressor is exhausted, the high-pressure gas will push the check valve to the side away from the second exhaust port to reduce the exhaust resistance, and the high-pressure gas will pass through the outer wall of the check valve and the inner wall of the partition on the installation cavity. between and through at least one exhaust passage.
当停机时，流出排气通道的部分高压气体会发生回流，高压气流会推动止回阀，同时，由于止回阀本身重力的因素，使得止回阀向靠近第二排气口的一侧运动，以部分封盖第二排气口，减小高压气体经第二排气口回流至压缩腔内，进而导致压缩机停机后反转的问题。When shutting down, part of the high-pressure gas flowing out of the exhaust channel will flow back, and the high-pressure air will push the check valve. At the same time, due to the gravity of the check valve itself, the check valve will move to the side close to the second exhaust port. , to partially cover the second exhaust port to reduce the high-pressure gas flowing back into the compression chamber through the second exhaust port, which will lead to the reverse rotation of the compressor after shutdown.
通过设置安装腔，将止回阀的至少一部分设于安装腔内，能够减小止回阀在压缩机壳体内轴向方向上的占用空间，进而降低压缩机整机在轴向方向上的占用空间，有利于实现压缩机的小型化。By providing the installation cavity, at least a part of the check valve is arranged in the installation cavity, which can reduce the space occupied by the check valve in the axial direction of the compressor shell, thereby reducing the occupation of the compressor machine in the axial direction space, which is conducive to the miniaturization of the compressor.
