[0044] As Figures 1 to 8 shown, the embodiments of the present disclosure provide a compressor and a compressor for a refrigeration device. The roller 20 in the compressor is connected to the sliding vane 30 through the hinge member 40 to achieve the relative fixation of the hinge member 40 and the sliding vane 30. In this way, when the roller 20 and the sliding vane 30 move at high speed, the hinge member 40 can fix the sliding vane 30 to the roller 20. With such an arrangement, it is possible to avoid the situation where the roller 20 and the sliding vane 30 are instantaneously separated and then come into contact again, thereby avoiding obvious noise in the compressor.
[0045] As Figures 1 to 8As shown in the figure, an embodiment of the present disclosure provides a compressor for a refrigeration device, which includes: a cylinder 10, a sliding vane 30, a roller 20, and a hinge member 40. The cylinder 10 is provided with a compression chamber 101 and a sliding vane groove 102 communicating with the compression chamber 101; the sliding vane 30 is slidably arranged in the sliding vane groove 102, the sliding vane 30 includes a hinge side facing the compression chamber 101, a clamping portion 31 is arranged on the hinge side, and the hinge side extends into the compression chamber 101; the roller 20 is arranged in the compression chamber 101, the roller 20 is provided with a hinge groove 21 corresponding to the sliding vane 30, and the hinge groove 21 is arranged in the vertical direction; the hinge member 40 is inserted into the hinge groove 21, and the hinge member 40 is provided with a clamping and mating portion 41 corresponding to the clamping portion 31 of the sliding vane 30, and the clamping portion 31 can be clamped to the clamping and mating portion 41; wherein, the hinge member 40 can rotate circumferentially in the hinge groove 21.
[0046] Specifically, the roller 20 is arranged in the compression chamber 101 and can roll in the compression chamber 101 along a preset direction. The sliding vane groove 102 is located on one side of the compression chamber 101, and the sliding vane groove 102 communicates with the compression chamber 101. The sliding vane 30 is arranged in the sliding vane groove 102, and the sliding vane 30 can move synchronously with the roller 20 along the sliding vane groove 102. An articulation groove 21 is provided on the outer wall surface of the roller 20, and the position of the articulation groove 21 corresponds to that of the sliding vane 30. The articulation groove 21 is arranged in the vertical direction in a form that penetrates the roller 20, so that the hinge member 40 can be inserted and installed into the articulation groove 21 from above or below the articulation groove 21. The cross-sections of the articulation groove 21 and the hinge member 40 are configured as corresponding semi-circles, so that when the hinge member 40 is installed in the articulation groove 21, the hinge member 40 can rotate circumferentially in the articulation groove 21. The sliding vane 30 and the hinge member 40 are correspondingly provided with a clamping portion 31 and a clamping and mating portion 41 to clamp the sliding vane 30 to the hinge member 40.
[0047] During the operation of the refrigeration device, the drive shaft of the compressor drives the roller 20 to roll along the inner wall surface of the compression chamber 101 in the compression chamber 101. At this time, the roller 20 drives the sliding vane 30 to move along the sliding vane groove 102 through the hinge member 40 to compress the refrigerant in the compression chamber 101.
[0048] It can be understood that during the refrigeration process, the roller 20 and the sliding vane 30 will move at high speed. If the roller 20 and the sliding vane 30 are separated and then come into contact, obvious noise will be generated, and the user experience is poor. At the same time, generally, the compressor needs to separate the compression chamber 101 into an intake side and an exhaust side through the roller 20 and the sliding vane 30 to realize the processes of intake, compression, and discharge of the refrigerant. Therefore, it is necessary to ensure that the roller 20 and the sliding vane 30 remain in contact during the movement process, so that the intake side and the exhaust side of the compression chamber 101 are in a sealed state, thereby avoiding the leakage of the refrigerant on the intake side and the exhaust side and affecting the compression effect.
[0049] When using the compressor for refrigeration equipment provided by the present application, the roller 20 can drive the sliding vane 30 to move synchronously through the hinge 40, and the hinge 40 can achieve relative fixation between the sliding vane 30 and the roller 20. With such a setting, the situation where the roller 20 and the sliding vane 30 are instantaneously separated and then contact again can be avoided, thereby avoiding obvious noise in the compressor, and at the same time, the compression effect of the refrigerant by the compressor can be ensured.
[0050] In practical applications, since the roller 20 needs to roll along the compression chamber 101, the included angle between the roller 20 and the sliding vane 30 will change with the movement. In this way, connecting the sliding vane 30 to the roller 20 through the hinge 40 can avoid interference of the sliding vane 30 with the movement of the roller 20.
[0051] As Figures 5 to 8 shown, in some embodiments, the sliding vane 30 extends to one side of the compression chamber 101 and is provided with a plurality of clamping grooves 311 to form a clamping portion 31, and at least one clamping groove 311 is provided on each of the two side wall surfaces of the sliding vane 30; the hinge 40 is provided with a mounting groove 401 corresponding to the sliding vane 30, and a plurality of clamping protrusions 411 are provided on the side wall of the mounting groove 401 corresponding to the plurality of clamping grooves 311; when the hinged side of the sliding vane 30 is inserted into the mounting groove, the clamping protrusions 411 can be embedded in the clamping grooves 311.
[0052] Specifically, the hinged side of the sliding vane 30 is provided with a clamping groove 311, the clamping groove 311 is arranged on the side wall surface of the sliding vane 30, and the part of the sliding vane 30 provided with the clamping groove 311 is always inside the compression chamber 101. The hinge 40 is provided with a mounting groove 401 corresponding to the sliding vane 30, and the hinged side of the sliding vane 30 can be inserted into the mounting groove 401. A clamping protrusion 411 is provided in the mounting groove 401 corresponding to the clamping groove 311. When the hinged side of the sliding vane 30 is inserted into the mounting groove 401, the clamping protrusion 411 can be embedded in the clamping groove 311 so that the sliding vane 30 is clamped to the hinge 40.
[0053] Optionally, the mounting groove 401 is vertically and penetratingly arranged on the hinge 40, the clamping protrusion 411 is vertically arranged on the side wall of the mounting groove 401, and the clamping groove 311 is vertically and penetratingly arranged on the side wall surface of the sliding vane 30. In this way, the hinged side of the sliding vane 30 can be inserted into the mounting groove 401 from the upper end of the mounting groove 401, and the clamping protrusion 411 can be embedded in the clamping groove 311, which is more convenient for installing the sliding vane 30 on the hinge 40.
[0054] Optionally, a plurality of clamping grooves 311 are provided on any side wall surface of the sliding vane 30, and a plurality of clamping protrusions 411 are correspondingly provided in the mounting groove 401. The plurality of clamping protrusions 411 can be respectively clamped in the plurality of clamping grooves 311 to improve the stability of the sliding vane 30 installed on the hinge 40.
[0055] As Figures 5 to 8As shown, in some embodiments, the width of the clamping groove 311 is greater than or equal to 0.5 mm; the depth of the clamping groove 311 is greater than or equal to 0.5 mm.
[0056] Specifically, the width of the clamping protrusion 411 is greater than or equal to 0.45 mm and less than the width of the clamping groove 311; the thickness of the clamping protrusion 411 is greater than or equal to 0.45 mm and less than the thickness of the clamping groove 311. In this way, when the clamping protrusion 411 is embedded in the clamping groove 311, the spacing between the clamping protrusion 411 and the clamping groove 311 can be reduced while increasing the contact area between the clamping protrusion 411 and the clamping groove 311, thereby ensuring the stability of the sliding piece 30 clamped to the hinge member 40.
[0057] In practical applications, the width and depth of the clamping groove 311 can be set according to the actual needs of the user. For example, the width of the clamping groove 311 can be 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm or 0.7 mm; the depth of the clamping groove 311 can be 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm or 0.7 mm.
[0058] As Figure 4 and Figure 8 As shown, in some embodiments, the inner diameter of the hinge groove 21 is the first diameter D, and the outer diameter of the hinge member 40 is the second diameter d; wherein, the difference between the first diameter D and the second diameter d is greater than or equal to 0.02 mm and less than or equal to 0.05 mm.
[0059] Specifically, the inner diameter of the hinge groove 21 is greater than the outer diameter of the hinge member 40, and the gap between the hinge groove 21 and the hinge member 40 is less than or equal to 0.05 mm. It can be understood that making the difference between the first diameter D and the second diameter d greater than or equal to 0.02 mm can prevent the gap between the hinge groove 21 and the hinge member 40 from being too small and affecting the rotation of the hinge member 40 in the hinge groove 21; making the difference between the first diameter D and the second diameter d less than or equal to 0.05 mm can prevent the gap between the hinge groove 21 and the hinge member 40 from being too large and causing the hinge member 40 and the roller 20 to collide and generate obvious noise.
[0060] In practical applications, the inner diameter of the hinge groove 21 and the outer diameter of the hinge member 40 can be set according to the actual needs of the user. For example, the difference between the first diameter D and the second diameter d can be 0.02 mm, 0.03 mm, 0.04 mm or 0.05 mm.
[0061] As Figure 4 and Figure 8As shown, in some embodiments, the hinge groove 21 is provided with an opening corresponding to the sliding piece 30. The size of the opening is greater than or equal to the thickness of the sliding piece 30, and the width of the opening is the first width B. Among them, the difference between the second diameter d and the first width B is greater than or equal to 0.01 mm.
[0062] Specifically, an opening is provided at the position of the hinge groove 21 corresponding to the sliding piece 30, and the size of the opening is greater than or equal to the thickness of the sliding piece 30. When the hinge member 40 is installed in the hinge groove 21, the hinged side of the sliding piece 30 can extend into the installation groove of the hinge member 40 through the opening of the hinge groove 21. Among them, the outer diameter of the hinge member 40 is greater than the width of the opening, and the difference between the outer diameter of the hinge member 40 and the width of the opening is greater than or equal to 0.01 mm to prevent the hinge member 40 from disengaging from the hinge groove 21 through the opening.
[0063] In practical applications, the width of the opening of the hinge groove 21 can be set according to the actual needs of the user. For example, the difference between the outer diameter of the hinge member 40 and the width of the opening can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm or 0.05 mm.
[0064] As Figures 5 to 8 shown, in some embodiments, the hinged side of the sliding piece 30 is configured as a T-shaped structure; the installation groove of the hinge member 40 is configured as a T-shaped structure corresponding to the hinged side of the sliding piece 30.
[0065] Specifically, the clamping groove 311 provided in the hinge groove 21 of the sliding piece 30 is arranged vertically, and there is a spacing between the clamping groove 311 and the side of the hinge groove 21, so that the hinge groove 21 of the sliding piece 30 is configured as a T-shaped structure. The installation groove is configured as a T-shaped structure corresponding to the hinged side of the sliding piece 30. With such a setting, the stability of the sliding piece 30 clamped in the hinge groove 21 can be further improved.
[0066] As Figure 5 shown, in some embodiments, the width of the hinged side of the sliding piece 30 is the second width t, and the thickness of the sliding piece 30 is the first thickness h. Among them, the second width t is greater than or equal to 1 / 2 of the first thickness h.
[0067] Specifically, the width of the hinged side of the sliding piece 30 refers to the maximum width at the T-shaped structure of the hinged side of the sliding piece 30, and the thickness of the sliding piece 30 refers to the maximum width of the part of the sliding piece 30 outside the hinged side. It can be understood that the greater the thickness of the sliding piece 30, the greater the force borne by the hinged side of the sliding piece 30. Therefore, making the width of the hinged side of the sliding piece 30 greater than or equal to 1 / 2 of the thickness of the sliding piece 30 can ensure the reliability of the sliding piece 30.
[0068] In practical applications, the width of the hinged side of the sliding piece 30 can be 1 / 2, 2 / 3, 3 / 4, 4 / 5 of the thickness of the sliding piece 30, or the width of the hinged side of the sliding piece 30 is equal to the thickness of the sliding piece 30.
[0069] As Figures 1 to 8 shown, in some embodiments, a DLC coating is attached to the outer wall surface of the hinge member 40; wherein, the hardness of the DLC coating is greater than or equal to a preset hardness, and the friction coefficient of the DLC coating is less than or equal to a preset friction coefficient.
[0070] Specifically, the DLC (Diamond Like Carbon) coating is completely attached to the outer wall surface of the hinge member 40, that is, the projection of the hinge groove 21 on the outer wall surface of the hinge member 40 completely falls on the DLC coating, so that the hinge member 40 contacts the hinge groove 21 completely through the DLC coating.
[0071] It can be understood that the DLC coating is a type of amorphous carbon film with properties similar to diamond, having high hardness, high resistivity, good optical properties, etc., and at the same time having its own unique tribological properties. In practical applications, since the roller 20 and the sliding piece 30 will move at high speed, and the hinge member 40 will rotate relative to the roller 20 in the hinge groove 21, this causes the hinge member 40 to inevitably collide and rub against the hinge groove 21. Therefore, attaching a DLC coating to the outer wall surface of the hinge member 40 can increase the hardness of the contact part between the hinge member 40 and the hinge groove 21 and reduce the friction coefficient of the hinge member 40.
[0072] Optionally, a DLC coating is also attached to the wall surface of the hinge groove 21 to increase the hardness of the contact part between the hinge groove 21 and the hinge member 40 and reduce the friction coefficient of the hinge groove 21.
[0073] In the above embodiments, the HV hardness (Vickers hardness) of the DLC coating is greater than or equal to 1000 N / mm2 and less than or equal to 1400 N / mm2; the thickness of the DLC coating is greater than or equal to 2 μm and less than or equal to 3 μm; the friction coefficient of the DLC coating is less than or equal to 0.05.
[0074] As Figures 3 to 6 shown, in some embodiments, the roller 20 is further provided with an oil storage groove 22, the oil storage groove 22 is arranged vertically corresponding to the hinge groove 21, and the oil storage groove 22 communicates with the hinge groove 21; a part of the sliding piece 30 inserted into the sliding piece groove 102 is provided with an oil guiding groove 32, and the oil guiding groove 32 extends from the upper end surface of the sliding piece 30 to the side wall surface.
[0075] Specifically, the oil storage tank 22 is located on one side of the hinge groove 21, and the oil storage tank 22 communicates with the hinge groove 21. The compressor further includes an oil supply device that can supply lubricating oil into the oil storage tank 22. At this time, the lubricating oil in the oil storage tank 22 can flow into the hinge groove 21 and be evenly applied to the surfaces of the hinge member 40 and the hinge groove 21 as the hinge member 40 rotates. With such a setting, the friction between the hinge member 40 and the hinge groove 21 can be further reduced to ensure the stability of the compressor. The oil storage tank 22 is arranged vertically to increase the supply amount of lubricating oil that the oil supply device can supply to the oil storage tank 22. At the same time, arranging the oil storage tank 22 corresponding to the hinge groove 21 vertically can also increase the communication area between the oil storage tank 22 and the hinge groove 21. Among them, the height of the upper end of the oil storage tank 22 is higher than the height of the upper end of the hinge member 40, and the height of the lower end of the oil storage tank 22 is lower than the height of the lower end of the hinge member 40. With such a setting, it can be ensured that the lubricating oil completely fills between the hinge member 40 and the hinge groove 21.
[0076] In the above embodiment, an oil guide groove 32 is provided in the part of the sliding vane 30 inserted into the sliding vane groove 102. At least a part of the oil guide groove 32 is located on the upper end surface of the sliding vane 30, and at least a part of the oil guide groove 32 is located on the side wall surface of the sliding vane 30 facing the exhaust side of the compression chamber 101. In this way, lubricating oil can also be supplied to the oil guide groove 32 through the oil supply device so that the lubricating oil fills between the sliding vane 30 and the sliding vane groove 102, thereby reducing the friction force between the sliding vane 30 and the sliding vane groove 102.
[0077] As Figures 1 to 8 shown, the embodiment of the present disclosure also provides a refrigeration device including: the above compressor for a refrigeration device.
[0078] Specifically, the refrigeration device includes a compressor that is used to compress the refrigerant in the refrigeration device. For the refrigeration device using the compressor provided in this application, the roller 20 in the compressor is connected through the hinge member 40 and the sliding vane 30 to achieve the relative fixation of the hinge member 40 and the sliding vane 30. In this way, when the roller 20 and the sliding vane 30 move at high speed, the hinge member 40 can fix the sliding vane 30 to the roller 20. With such a setting, the situation where the roller 20 and the sliding vane 30 are instantaneously separated and then contacted can be avoided, thereby avoiding obvious noise in the compressor.
