[0042] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.
[0043] A rotary compressor generally mainly includes a cylinder, a sliding vane, and a roller. The sliding vane and the roller can move along a preset trajectory in the compression chamber of the cylinder to compress the refrigerant in the compression chamber. However, if the air pressure in the compression chamber is too high, it may cause the problem that the sliding vane and the roller separate and then collide with each other quickly, which will generate a "ticking" noise. At the same time, if the above situation occurs repeatedly for a long time, it will also cause wear of the sliding vane and the roller, thereby affecting the reliability of the compressor.
[0044] As Figures 1 to 8 shown, the embodiments of the present disclosure provide a rotary compressor and an air conditioner for an air conditioner. During the operation of the air conditioner, the compression chamber 11 will be in a high-pressure state. Since the sliding vane 20 is provided with a first pressure relief channel 21, the air pressure in the exhaust chamber 111 can be relieved through the first pressure relief channel 21 to the pressure relief chamber, so as to avoid the separation of the sliding vane 20 and the roller 31 due to too high air pressure in the compression chamber 11, and thus avoid obvious noise of the compressor.
[0045] As Figures 1 to 8As shown in the figure, an embodiment of the present disclosure provides a rotary compressor for an air conditioner, including: a cylinder 10 and a sliding vane 20. The cylinder 10 is provided with a compression chamber 11, a sliding vane groove 12 and a pressure relief chamber. The compression chamber 11 includes an exhaust chamber 111. The sliding vane groove 12 is respectively communicated with the compression chamber 11 and the pressure relief chamber, and the pressure relief chamber is communicated with the external environment; the sliding vane 20 is slidably arranged in the sliding vane groove 12, and a first pressure relief channel 21 is arranged on the exhaust side wall 201 of the sliding vane 20 facing the exhaust chamber 111; when the sliding vane 20 moves to the upper dead center, the first pressure relief channel 21 is respectively communicated with the exhaust chamber 111 and the pressure relief chamber; wherein, the flow direction of the refrigerant in the first pressure relief channel 21 is defined as flowing from the exhaust chamber 111 to the pressure relief chamber.
[0046] Specifically, the rotary compressor further includes a roller 31. The roller 31 is rotatably arranged in the compression chamber 11, and the sliding vane 20 is in rolling contact with the roller 31. The roller 31 abuts against the side wall of the compression chamber 11, and the sliding vane 20 can cooperate with the roller 31 to divide the compression chamber 11 into two sub-chambers. The cylinder 10 is further provided with an exhaust port, and the sub-chamber where the compression chamber 11 is communicated with the exhaust port is the exhaust chamber 111. The roller 31 and the sliding vane 20 can move along a preset track in the compression chamber 11 to compress the refrigerant in the compression chamber 11. When the roller 31 moves towards the sliding vane 20 and abuts against the sliding vane groove 12, the sliding vane 20 and the roller 31 are in the upper dead center position. At this time, both ends of the first pressure relief channel 21 are communicated with the exhaust chamber 111 and the pressure relief chamber respectively, and the refrigerant in the exhaust chamber 111 can flow through the first pressure relief channel 21 to the pressure relief chamber, and then flow from the pressure relief chamber to the external environment to realize the pressure relief of the exhaust chamber 111. Such a setting can avoid excessive air pressure in the exhaust chamber 111, resulting in the separation of the sliding vane 20 and the roller 31, thereby avoiding obvious noise and improving the reliability of the compressor.
[0047] In practical applications, the rotary compressor further includes an elastic element 32, and the elastic element 32 is used to push the sliding vane 20 towards the roller 31. The back pressure Fa of the sliding vane 20 = Fk + Fpd + Fm, and the separating force Fb of the sliding vane 20 = Fps + Fpc + Fμ. Wherein, Fk is the spring force of the elastic element 32, Fpd is the discharge pressure, Fm is the inertia force of the sliding vane 20, Fps is the pressure on the suction side of the sliding vane 20, Fpc is the pressure on the exhaust side of the sliding vane 20, and Fμ is the friction force between the sliding vane 20 and the sliding vane groove 12. When the back pressure Fa of the sliding vane 20 is less than the separating force Fb of the sliding vane 20, obvious noise of the sliding vane 20 will be generated. When the sliding vane 20 is at the upper dead center, the compressor is in the exhaust process, and at this time, the pressure in the exhaust chamber 111 of the compression chamber 11 will be relatively large. Therefore, arranging the first pressure relief channel 21 on the exhaust side wall 201 of the sliding vane 20 to relieve the pressure of the exhaust chamber 111 can reduce the pressure Fps on the exhaust side of the sliding vane 20, thereby reducing the noise of the compressor.
[0048] According to tests, when the sliding vane 20 is at the upper extreme position, the exhaust chamber 111 is depressurized through the first pressure relief channel 21, which can reduce the pressure Fps on the exhaust side of the sliding vane 20 to 90% of the original pressure and shorten the noise duration to 90% of the original pressure, significantly reducing the noise generated by the compressor.
[0049] As Figure 4 and Figure 5 shown, in some embodiments, the first pressure relief channel 21 is configured as a Tesla valve structure. The first pressure relief channel 21 includes an inlet end and an outlet end; wherein, the inlet end of the first pressure relief channel 21 is communicated with the exhaust chamber 111, and the outlet end of the first pressure relief channel 21 is communicated with the pressure relief cavity.
[0050] Specifically, a groove body with a Tesla valve structure is provided on the exhaust side wall 201 of the sliding vane 20 to form the first pressure relief channel 21. Configuring the first pressure relief channel 21 as a Tesla valve structure can prevent the airflow in the pressure relief cavity from flowing through the first pressure relief channel 21 to the exhaust chamber 111, thereby avoiding the occurrence of airflow disorder in the exhaust chamber 111. With this setting, there is no need to set other check valve structures to achieve the one-way flow of the airflow in the first pressure relief channel 21, which is more convenient for users to process the first pressure relief channel 21 on the exhaust side wall 201 of the sliding vane 20.
[0051] As Figure 4 and Figure 5 shown, in some embodiments, the distance between the outlet end of the first pressure relief channel 21 and the side of the sliding vane 20 is greater than or equal to a preset distance.
[0052] Specifically, the cylinder 10 is further provided with an air inlet, and the sub-chamber of the cylinder 10 communicated with the air inlet constitutes the suction chamber 112. The outlet end of the first pressure relief channel 21 extends in a direction away from the compression chamber 11, and there is a certain distance between the first pressure relief channel 21 and the side of the sliding vane 20. With this setting, the gas tightness of the suction chamber 112 can be ensured.
[0053] In some embodiments, the size of the inlet end of the first pressure relief channel 21 is less than or equal to a preset size.
[0054] Specifically, the size of the inlet end of the first pressure relief channel 21 can be set according to the actual needs of the user. For example, the size of the inlet end can be 1mm, 2mm or 3mm. Making the size of the inlet end of the first pressure relief channel 21 less than or equal to the preset size can prevent the air flow rate flowing from the exhaust chamber 111 into the first pressure relief channel 21 from being too large, resulting in too low pressure in the exhaust chamber 111, thereby ensuring the normal progress of the compression process.
[0055] As Figures 1 to 8As shown, in some embodiments, the compression chamber 11 further includes a suction chamber 112; a second pressure relief passage 22 is provided on the suction side wall 202 of the sliding vane 20 facing the suction chamber 112; wherein, the flow direction of the refrigerant in the second pressure relief passage 22 is defined as flowing from the suction chamber 112 to the pressure relief chamber; when the sliding vane 20 moves to the lower dead point, both ends of the second pressure relief passage 22 are communicated with the suction chamber 112 and the pressure relief chamber respectively.
[0056] Specifically, the suction chamber 112 is communicated with the suction port of the cylinder 10 to suck the refrigerant through the suction port. When the roller 31 moves towards the sliding vane 20 and abuts against the other side of the cylinder 10 relative to the sliding vane groove 12, the sliding vane 20 and the roller 31 are at the lower dead point position. At this time, both ends of the second pressure relief passage 22 are communicated with the suction chamber 112 and the pressure relief chamber respectively, and the refrigerant in the suction chamber 112 can flow to the pressure relief chamber through the second pressure relief passage 22 and then flow from the pressure relief chamber to the external environment to realize the pressure relief of the suction chamber 112. Such a setting can avoid excessive air pressure in the suction chamber 112, resulting in the separation of the sliding vane 20 and the roller 31, thereby avoiding obvious noise and improving the reliability of the compressor.
[0057] When the sliding vane 20 is at the lower dead point, the compressor is in the suction process, and at this time, the pressure in the suction chamber 112 of the compression chamber 11 is relatively high. Therefore, a second pressure relief passage 22 is provided on the suction side wall 202 of the sliding vane 20 to relieve the pressure of the suction chamber 112, which can reduce the suction side pressure Fpc of the sliding vane 20 and further reduce the noise of the compressor.
[0058] According to the test, when the sliding vane 20 is at the lower dead point, relieving the pressure of the suction chamber 112 through the second pressure relief passage 22 can reduce the suction side pressure Fpc of the sliding vane 20 to 95% of the original pressure and shorten the noise duration to 92% of the original pressure, significantly reducing the noise generated by the compressor.
[0059] In the above embodiment, the length of the first pressure relief passage 21 is less than the length of the second pressure relief passage 22. In this way, when the sliding vane 20 is at the lower dead point, the second pressure relief passage 22 can communicate the suction chamber 112 and the pressure relief chamber, and the first pressure relief passage 21 is disconnected from the pressure relief chamber. Such a setting can avoid the refrigerant in the exhaust chamber 111 flowing into the pressure relief chamber through the first pressure relief passage 21, thereby ensuring the stable air pressure in the compression chamber 11.
[0060] As Figure 7 and Figure 8 shown, in some embodiments, the second pressure relief passage 22 is configured as a Tesla valve structure, and the second pressure relief passage 22 includes an inlet end and an outlet end; wherein, the inlet end of the second pressure relief passage 22 is communicated with the suction chamber 112, and the outlet end of the second pressure relief passage 22 is communicated with the pressure relief chamber.
[0061] Specifically, the suction side wall 202 of the slide 20 is provided with a groove body of a Tesla valve structure to form the second pressure relief channel 22. The second pressure relief channel 22 is configured as a Tesla valve structure, which can prevent the airflow in the pressure relief cavity from flowing to the suction chamber 112 through the second pressure relief channel 22, thereby preventing the airflow turbulence in the suction chamber 112. With such a configuration, the one-way flow of the airflow in the second pressure relief channel 22 can be achieved without providing other one-way valve structures, which makes it more convenient for users to process the second pressure relief channel 22 on the suction side wall 202 of the slide 20.
[0062] like Figure 7 and Figure 8 As shown, in some embodiments, the distance between the air outlet end of the second pressure relief channel 22 and the side of the sliding vane 20 is greater than or equal to a preset distance.
[0063] Specifically, the outlet end of the second pressure relief channel 22 extends away from the compression chamber 11, and there is a certain distance between the second pressure relief channel 22 and the side of the slide 20. Such an arrangement can ensure the gas tightness of the exhaust chamber 111.
[0064] In some embodiments, the size of the air inlet end of the second pressure relief passage 22 is smaller than or equal to a preset size.
[0065] Specifically, the size of the air inlet end of the second pressure relief channel 22 can be set according to the actual needs of the user, for example, the size of the air inlet end can be 1mm, 2mm or 3mm. By making the size of the air inlet end of the second pressure relief channel 22 smaller than or equal to the preset size, it is possible to avoid excessive air flow from the suction chamber 112 into the second pressure relief channel 22, resulting in too low a pressure in the suction chamber 112, thereby ensuring the normal progress of the compression process.
[0066] like Figures 1 to 8 As shown, in some embodiments, the cylinder 10 is provided with a spring chamber 13 at one end of the sliding vane groove 12 away from the compression chamber 11 to form a pressure relief chamber.
[0067] Specifically, the spring chamber 13 is arranged in the vertical direction and is arranged in the form of penetrating the cylinder 10. The elastic element 32 is arranged in the spring chamber 13, and the two ends of the elastic element 32 are respectively abutted against the side wall surface of the spring chamber 13 and the slide 20 to push the slide 20 in the direction of the roller 31. The spring chamber 13 is configured as a pressure relief chamber, which can make the structure of the cylinder 10 more compact. At the same time, the spring chamber 13 is arranged in the form of penetrating the cylinder 10, which can increase the pressure relief effect of the spring chamber 13.
[0068] like Figures 1 to 8 As shown, an embodiment of the present disclosure further provides an air conditioner including: the above-mentioned rotary compressor for the air conditioner.
[0069] Specifically, for an air conditioner adopting the rotary compressor provided by the present application, during the operation of the air conditioner, the compression chamber 11 will be in a high-pressure state. Since the sliding vane 20 is provided with a first pressure relief passage 21, the air pressure in the exhaust chamber 111 can be relieved through the first pressure relief passage 21 to the pressure relief chamber, so as to prevent the sliding vane 20 from separating from the roller 31 due to excessive air pressure in the compression chamber 11, and further prevent obvious noise from occurring in the compressor.
