Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a compressor and a refrigeration device. Background Art

[0002] In order to meet the energy-saving requirements, the energy efficiency level of refrigeration equipment has been further improved, and the efficiency requirements for compressors have become increasingly higher. In rotary compressors, friction power consumption accounts for about 8% of the total power consumption. Improving friction power consumption has a great effect on improving compressor energy efficiency. Among them, the wear between the vane and the vane groove accounts for about 20% of the total friction power consumption.

[0003] In the related technology, the vane head presses against the outer circle of the piston to divide the compression chamber of the cylinder into an intake chamber and an exhaust chamber. The rotation of the crankshaft can drive the piston to rotate. When the piston rotates, the gas is sucked in from the intake chamber and discharged from the compression chamber after compression.

[0004] During the operation of the compressor, the suction chamber and the exhaust chamber form high-pressure and low-pressure areas. Under the action of the pressure difference, the head of the vane tilts toward the suction chamber, and the tail of the vane tilts toward the exhaust chamber. During the reciprocating motion of the vane, the inclination of the vane causes the friction between the vane and the wall of the vane groove to increase, causing wear of components and increasing the friction power consumption of the compressor, resulting in a decrease in compressor performance. Summary of the invention

[0005] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, a first aspect of the present application provides a compressor.

[0007] A second aspect of the present application provides a refrigeration device.

[0008] In view of this, the first aspect of the present application proposes a compressor, comprising: a shell; a cylinder, arranged in the shell, the cylinder is provided with a working chamber, a vane groove and a connecting portion, the vane groove is connected to the working chamber, the working chamber has an intake side and an exhaust side, and the connecting portion is connected to the side of the vane groove close to the exhaust side; a bearing assembly, arranged in the shell, the bearing assembly is provided with a first channel; a muffler, arranged in the shell, the muffler is provided with a high-pressure chamber, and the first channel connects the connecting portion and the high-pressure chamber.

[0009] A compressor provided in the present application includes a shell, a cylinder, a bearing assembly and a muffler.

[0010] The cylinder, bearing assembly and muffler are all arranged in the shell, that is, the shell serves as a mounting carrier for the cylinder, bearing assembly and muffler, has the function of mounting and fixing the cylinder, bearing assembly and muffler, and can ensure the matching dimensions of the cylinder, bearing assembly and muffler.

[0011] The cylinder is provided with a working chamber, a vane groove and a connecting portion. The vane groove is connected with the working chamber. The working chamber has an intake side and an exhaust side. The connecting portion is connected with a side of the vane groove close to the exhaust side of the working chamber.

[0012] The bearing assembly is provided with a first channel, the first channel is communicated with the high pressure chamber of the muffler, and the first channel is communicated with the communication part. That is, the communication part and the high pressure chamber of the muffler are communicated through the first channel.

[0013] It is understandable that the gas in the high-pressure chamber of the muffler flows to the first channel through the exhaust hole of the muffler, flows to the connecting part through the first channel, and enters the vane groove through the connecting part. The gas entering the vane groove through the connecting part acts on the vane in the vane groove to balance the pressure of the front and rear ends of the vane close to the exhaust side of the working chamber, and inhibits the vane from rotating relative to the vane groove. In this way, the inclination angle of the vane in the vane groove relative to the vane groove can be reduced, and the probability of the vane contacting the groove wall of the vane groove is reduced. The problem of vane inclination caused by the suction and exhaust pressure difference in the related art is solved, and the friction between the vane and the groove wall of the vane groove is effectively reduced, which is conducive to reducing wear, and can improve the reliability of the use of the vane, which is conducive to improving the performance of the compressor.

[0014] This arrangement makes reasonable use of the existing structure of the compressor (such as the muffler and the bearing assembly). By providing a connecting portion and a first channel, and making the first channel connect the high-pressure chamber of the muffler and the connecting portion, a portion of the high-pressure gas of the muffler can enter the vane groove through the first channel and the connecting portion. That is, the flow path of a portion of the high-pressure gas of the muffler is changed, thereby balancing the consistency of the force on the exhaust side of the vane close to the working chamber, reducing the deflection angle of the vane relative to the vane groove, and reducing the contact stress and friction loss between the vane and the vane groove.

[0015] The compressor described above in this application may also have the following additional technical features:

[0016] In some embodiments, optionally, the cylinder is further provided with a mounting hole, and the compressor further includes: a sliding vane slidably provided in the sliding vane groove; and an elastic member provided in the mounting hole, and the elastic member is connected to the sliding vane.

[0017] In this embodiment, the structure of the compressor is further defined, and the compressor also includes a vane, which is slidably disposed in the vane groove, that is, the vane is slidably connected to the vane groove, and the vane can reciprocate relative to the vane groove driven by the piston.

[0018] The cylinder is also provided with a mounting hole, and the compressor also includes an elastic member, which is provided in the mounting hole. The mounting hole has the function of mounting and fixing the elastic member, and provides effective and reliable structural support to ensure the matching size of the elastic member and the sliding plate. The elastic member is connected to the sliding plate, and the elastic member provides elastic force for the sliding plate to reset when the sliding plate moves relative to the sliding plate groove.

[0019] Optionally, the elastic member includes a spring, a tension spring, etc., which are not listed here one by one.

[0020] In some embodiments, optionally, the connecting portion is arranged separately from the mounting hole.

[0021] In this embodiment, the matching structure of the connecting portion and the mounting hole is limited so that the connecting portion and the mounting hole are arranged separately, that is, the connecting portion and the mounting hole are two relatively independent structures. In other words, the connecting portion and the mounting hole are not connected to each other.

[0022] It can be understood that in order to ensure the use state of the elastic part, oil is provided in the mounting hole. Since the mounting hole and the connecting part are separately arranged, the oil in the mounting hole will not enter the connecting part. Similarly, the low-pressure gas at the mounting hole will not enter the connecting part. In this way, the balance and controllability of the force acting on the sliding vane in the sliding vane groove through the connecting part can be ensured, providing effective and reliable structural support for balancing the pressure of the front and rear ends of the sliding vane on the exhaust side close to the working chamber.

[0023] In some embodiments, optionally, the connecting portion includes a sink; the minimum distance from any point on the sink's slot to the center of the cylinder is recorded as L1, the maximum distance from any point on the sink's slot to the center of the cylinder is recorded as L2, the maximum distance from any point on the sink's slot wall to the center of the cylinder is recorded as L3, the inner diameter of the cylinder is recorded as D, the eccentricity of the compressor's crankshaft is recorded as e, and the length of the vane is recorded as L; wherein, D / 2<L1<(D / 2)+L-2×e, and L2<L3.

[0024] In this embodiment, the matching structure of the communication portion, the cylinder, the crankshaft of the compressor and the sliding vane is defined.

[0025] The connecting portion includes a sink groove, the sink groove is connected to a side of the sliding vane groove close to the exhaust side, and the sink groove is connected to the first channel.

[0026] The sink has a notch. The minimum distance from any point on the notch of the sink to the center of the cylinder is defined as L1. The maximum distance from any point on the notch of the sink to the center of the cylinder is defined as L2. The maximum distance from any point on the wall of the sink to the center of the cylinder is defined as L3. It can be understood that the wall of the sink refers to the rest of the sink excluding the notch.

[0027] Among them, the inner diameter of the cylinder is defined as D, the eccentricity of the crankshaft of the compressor is defined as e, and the length of the sliding vane is defined as L.

[0028] And the relationship between L1, L2, L3, D, e and L is defined to satisfy D / 2<L1<(D / 2)+L-2×e, and L2<L3, that is, the matching structure of the center of the cylinder, the sink groove, the crankshaft and the sliding vane is defined. In this way, while ensuring the effectiveness and feasibility of the sliding of the sliding vane relative to the sliding vane groove, the air tightness of the sink groove can be ensured to avoid air leakage, and low-pressure gas can be prevented from entering the sink groove, resulting in uneven force on the sliding vane and deflection relative to the sliding vane groove, thereby providing effective and reliable structural support for reducing the friction between the sliding vane and the groove wall of the sliding vane groove.

[0029] In some embodiments, optionally, the bearing assembly includes: a first bearing; a second bearing, the cylinder is located between the first bearing and the second bearing, and at least one of the first bearing and the second bearing is provided with a first channel.

[0030] In this embodiment, the structure of the bearing assembly is defined, and optionally, the bearing assembly includes a first bearing and a second bearing, and the cylinder is located between the first bearing and the second bearing.

[0031] At least one of the first bearing and the second bearing is provided with a first channel, that is, the first bearing is provided with the first channel, or the second bearing is provided with the first channel, or both the first bearing and the second bearing are provided with the first channel. In other words, at least one of the first bearing and the second bearing serves as a mounting carrier for the first channel, so as to ensure that the high-pressure gas of the muffler can flow to the sliding vane groove through the first channel and the connecting portion.

[0032] Optionally, when the compressor is working, the high-pressure refrigerant in the cylinder will flow to the exhaust port of the shell through the exhaust channel of the bearing assembly, and then flow into the condenser through the exhaust port.

[0033] In some embodiments, optionally, when the number of the cylinder is one, the first bearing is provided with a first channel, and the first bearing is located at a side of the cylinder facing the motor of the compressor.

[0034] In this embodiment, when the number of the cylinder is one, the cylinder is located between the first bearing and the second bearing.

[0035] The compressor further includes a motor, and the first bearing is located on the side of the motor of the cylinder facing the compressor, that is, the distance from the first bearing to the motor is smaller than the distance from the second bearing to the motor. It can also be said that the first bearing is located between the motor and the cylinder.

[0036] The first bearing closer to the motor is used as a mounting carrier of the first channel to ensure the communication between the vane slot and the high-pressure chamber of the muffler.

[0037] In some embodiments, optionally, when the number of cylinders is multiple, the compressor also includes: a partition, the partition is located between the first bearing and the second bearing, each cylinder is connected to the partition, the partition is provided with a second channel, the connecting part and the first channel are connected through the second channel; the first bearing and the second bearing are both provided with a first channel.

[0038] In this embodiment, when there are multiple cylinders, the compressor further comprises a partition plate, and the partition plate is located between the first bearing and the second bearing. Any cylinder among the multiple cylinders is connected to the partition plate.

[0039] The partition plate is provided with a second channel, the second channel is communicated with the communication portion, and the second channel is communicated with the first channel. That is, the communication portion and the first channel are communicated through the second channel.

[0040] The first bearing is provided with a first channel, and the second bearing is provided with a second channel. This arrangement can meet the use requirement that the vane groove of any cylinder in the plurality of cylinders is connected to the high-pressure chamber of the muffler.

[0041] Optionally, the partition is provided with a first air intake port and an air intake channel, each cylinder is provided with a second air intake port, and the shell is provided with a first opening and a second opening. The refrigeration device also includes a condenser, an expansion device, an evaporator, a liquid reservoir, a compressor, a first air intake pipe, and a plurality of second air intake pipes. The condenser is connected between the compressor and the expansion device, the evaporator is connected between the expansion device and the liquid reservoir, the liquid reservoir is connected to the first opening and the plurality of second openings, the first air intake port is connected to the first opening through the first air intake pipe, and each second air intake port is connected to a second opening through the first second air intake pipe.

[0042] The high-pressure refrigerant flowing out of the compressor flows to the condenser and becomes liquid refrigerant. Then, the high-pressure liquid refrigerant passes through the expansion device and becomes low-pressure evaporative refrigerant under the action of the evaporator. The low-pressure refrigerant after flowing through the liquid storage tank then flows into the compressor through the first suction pipe and multiple second suction pipes.

[0043] The low-pressure refrigerant of the liquid accumulator can enter the compressor through the first air inlet of the partition and the second air inlet of the multiple cylinders at the same time, and the low-pressure refrigerant in the air inlet channel of the partition will flow to the compression chambers of the multiple cylinders. Compared with the low-pressure refrigerant of the liquid accumulator only entering the compression chambers of the multiple cylinders through the air inlets, this setting increases the amount of refrigerant sucked into the compression chambers of the multiple cylinders without changing the existing structure of the cylinders, thereby increasing the volumetric efficiency of the compressor, which is conducive to improving the performance and market competitiveness of the compressor.

[0044] It can be understood that, since the compression chambers of the multiple cylinders are connected to the suction channel, the refrigerant in the suction channel of the partition can flow to the compression chamber of each cylinder to increase the volumetric efficiency of the compressor.

[0045] In some embodiments, optionally, the first bearing and the second bearing both include a first bearing segment and a second bearing segment, the first bearing segment is connected to the circumferential side of the second bearing segment; along the height direction of the compressor, the thickness of the first bearing segment is less than the thickness of the second bearing segment; at least one of the first bearing segment of the first bearing and the first bearing segment of the second bearing is provided with a first channel.

[0046] In this embodiment, the structures of the first bearing and the second bearing are further defined.

[0047] The first bearing includes a first bearing section and a second bearing section, the first bearing section is connected to the circumference of the second bearing section, and the thickness of the first bearing section in the height direction of the compressor is smaller than the thickness of the second bearing section in the height direction of the compressor.

[0048] The second bearing includes a first bearing section and a second bearing section, wherein the first bearing section is connected to the circumferential side of the second bearing section. The thickness of the first bearing section in the height direction of the compressor is smaller than the thickness of the second bearing section in the height direction of the compressor.

[0049] At least one of the first bearing section of the first bearing and the first bearing section of the second bearing is provided with a first channel. That is, the first bearing section of the first bearing is provided with a first channel, or the first bearing section of the second bearing is provided with a first channel, or the first bearing section of the first bearing and the first bearing section of the second bearing are both provided with a first channel. In other words, the first channel is arranged on the thinner portion of the first bearing and the second bearing. In this way, the processing difficulty of the first channel can be reduced, the processing technology of the first channel can be simplified, and the processing efficiency of the first channel can be improved, thereby reducing the production cost of the product.

[0050] In some embodiments, optionally, the cylinder or the bearing assembly is provided with a guide groove, and the connecting portion and the first channel are connected through the guide groove.

[0051] In this embodiment, when the distance between the connecting portion and the first channel is far, that is, the first channel and the connecting portion cannot be directly connected, a guide groove can be provided in the cylinder or in the bearing assembly to connect the first channel and the connecting portion through the guide groove. That is, the connecting portion and the first channel are connected through the guide groove.

[0052] This arrangement reasonably utilizes the existing structure of the cylinder and the bearing assembly, so that when the connecting portion and the first channel cannot be directly connected, the purpose of connecting the first channel and the connecting portion can be achieved through the guide groove on the cylinder or the bearing assembly. This arrangement is processing feasible, avoids the investment of additional devices to connect the first channel and the connecting portion, and is conducive to reducing the production cost of the compressor.

[0053] In some embodiments, optionally, the first passage extends along a height direction of the compressor.

[0054] In this embodiment, the extension direction of the first channel is further defined. Specifically, the first channel extends along the height direction of the compressor.

[0055] It can be understood that, along the height direction of the compressor, the first bearing has a first end face and a second end face that are opposite and spaced apart, and the first channel runs through the first end face and the second end face.

[0056] And / or, along the height direction of the compressor, the second bearing has a third end surface and a fourth end surface that are opposite to and spaced apart from each other, and the first channel runs through the third end surface and the fourth end surface.

[0057] In some embodiments, optionally, a side wall of the bearing assembly is provided with a first opening, an axial end surface of the bearing assembly is provided with a second opening, and the first channel connects the first opening and the second opening.

[0058] In this embodiment, the extension direction of the first channel is further defined. Specifically, the first channel is arranged in a curved manner, such as the first channel is arranged in an "L" shape.

The side wall of the bearing assembly is provided with a first opening, the axial end face of the bearing assembly is provided with a second opening, and the first channel connects the first opening and the second opening.

[0060] For example, the first bearing has a side wall and an axial end face. The side wall of the first bearing is provided with a first opening, the axial end face of the first bearing is provided with a second opening, and the first channel connects the first opening and the second opening.

[0062] In some embodiments, optionally, on a cross section of the first channel, a maximum distance between any two points of the first channel is denoted as d, where d≥1 mm.

[0063] In this embodiment, the structure of the first channel is further defined, so that the first channel is sectioned along the length direction perpendicular to the first channel, and the section is the cross section of the first channel. The maximum distance between any two points on the cross section is d, where d≥1mm. This setting can ensure the flow rate of the first channel, the amount of high-pressure gas entering the slide groove per unit time, and provide effective and reliable structural support for balancing the pressure of the front and rear ends of the slide close to the exhaust side of the working chamber.

DETAILED DESCRIPTION

[0093] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. 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.

[0094] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0095] Refer to the following Figures 1 to 22 A compressor 10 and a refrigeration device according to some embodiments of the present application.

[0096] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 , Fig.17 , Fig.18 , Fig.19 , Fig. 20 , Fig.21 and Fig. 22 As shown, a compressor 10 according to some embodiments of the present application includes a housing 100 , a cylinder 200 , a bearing assembly 300 and a muffler 400 .

[0097] The cylinder 200 is disposed in the housing 100 .

[0098] The cylinder 200 is provided with a working chamber 210 , a sliding vane groove 220 and a connecting portion 230 .

[0099] The sliding vane groove 220 is communicated with the working chamber 210 .

[0100] The working chamber 210 has an intake side and an exhaust side.

[0101] The communication portion 230 is communicated with a side of the vane groove 220 close to the exhaust side.

[0102] The bearing assembly 300 is disposed in the housing 100 , and the bearing assembly 300 is provided with a first passage 310 .

[0103] The muffler 400 is disposed in the housing 100 . The muffler 400 is provided with a high-pressure chamber 410 . The first passage 310 communicates with the communication portion 230 and the high-pressure chamber 410 .

[0104] In this embodiment, the compressor 10 includes a housing 100 , a cylinder 200 , a bearing assembly 300 , and a muffler 400 .

[0105] The cylinder 200, the bearing assembly 300 and the muffler 400 are all arranged in the shell 100, that is, the shell 100 serves as an installation carrier for the cylinder 200, the bearing assembly 300 and the muffler 400, has the function of installing and fixing the cylinder 200, the bearing assembly 300 and the muffler 400, and can ensure the matching dimensions of the cylinder 200, the bearing assembly 300 and the muffler 400.

[0106] Among them, the cylinder 200 is provided with a working chamber 210, a vane groove 220 and a connecting portion 230. The vane groove 220 is connected to the working chamber 210. The working chamber 210 has an intake side and an exhaust side. The connecting portion 230 is connected to the side of the vane groove 220 close to the exhaust side of the working chamber 210.

[0107] The bearing assembly 300 is provided with a first passage 310, which is communicated with the high pressure chamber 410 of the muffler 400 and the first passage 310 is communicated with the communication portion 230. That is, the communication portion 230 and the high pressure chamber 410 of the muffler 400 are communicated through the first passage 310.

[0108] It is understandable that the gas in the high-pressure chamber 410 of the muffler 400 flows to the first channel 310 through the exhaust hole of the muffler 400, flows to the connecting portion 230 through the first channel 310, and enters the vane slot 220 through the connecting portion 230. The gas entering the vane slot 220 through the connecting portion 230 acts on the vane 1000 in the vane slot 220 to balance the pressure of the front and rear ends of the vane 1000 close to the exhaust side of the working chamber 210, and inhibits the vane 1000 from rotating relative to the vane slot 220. In this way, the inclination angle of the vane 1000 in the vane slot 220 relative to the vane slot 220 can be reduced, and the probability of the vane 1000 contacting the slot wall of the vane slot 220 is reduced. The problem of vane tilt caused by the suction and exhaust pressure difference in the related art is solved, and the friction between the vane 1000 and the groove wall of the vane groove 220 is effectively reduced, which is beneficial to reducing wear and can improve the reliability of the use of the vane 1000, which is beneficial to improving the performance of the compressor 10.

[0109] This arrangement makes reasonable use of the existing structure of the compressor 10 (such as the muffler 400 and the bearing assembly 300). By providing the connecting portion 230 and the first channel 310, and making the first channel 310 connect the high-pressure chamber 410 of the muffler 400 and the connecting portion 230, a portion of the high-pressure gas of the muffler 400 can enter the vane groove 220 through the first channel 310 and the connecting portion 230, that is, the flow path of a portion of the high-pressure gas of the muffler 400 is changed, thereby balancing the consistency of the force on the exhaust side of the vane 1000 close to the working chamber 210, reducing the deflection angle of the vane 1000 relative to the vane groove 220, and reducing the contact stress and friction loss between the vane 1000 and the vane groove 220.

[0110] In some embodiments, optionally, Figure 1 , Figure 2 , Figure 5 , Figure 7 , Fig.17 , Fig.19 and Fig. 22 As shown, the cylinder 200 is further provided with a mounting hole 240 , and the compressor 10 further includes a sliding vane 1000 and an elastic member 1100 .

[0111] The sliding plate 1000 is slidably disposed in the sliding plate slot 220 .

[0112] The elastic member 1100 is disposed in the mounting hole 240 , and the elastic member 1100 is connected to the sliding sheet 1000 .

[0113] In this embodiment, the structure of the compressor 10 is further limited. The compressor 10 also includes a vane 1000. The vane 1000 is slidably disposed in the vane groove 220. That is, the vane 1000 is slidably connected to the vane groove 220. The vane 1000 can reciprocate relative to the vane groove 220 driven by the piston 800.

[0114] The cylinder 200 is also provided with a mounting hole 240, and the compressor 10 further includes an elastic member 1100, which is provided in the mounting hole 240. The mounting hole 240 has the function of mounting and fixing the elastic member 1100, and provides effective and reliable structural support to ensure the matching size of the elastic member 1100 and the sliding plate 1000. The elastic member 1100 is connected to the sliding plate 1000, and the elastic member 1100 provides elastic force when the sliding plate 1000 moves relative to the sliding plate slot 220, so as to reset the sliding plate 1000.

[0115] Optionally, the elastic member 1100 includes a spring, a tension spring, etc., which are not listed here one by one.

[0116] In some embodiments, optionally, Figure 2 , Figure 5 and Figure 7 As shown, the communication portion 230 is arranged separately from the mounting hole 240 .

[0117] In this embodiment, by limiting the matching structure of the connecting portion 230 and the mounting hole 240, the connecting portion 230 and the mounting hole 240 are arranged separately, that is, the connecting portion 230 and the mounting hole 240 are two relatively independent structures. In other words, the connecting portion 230 and the mounting hole 240 are not connected to each other.

[0118] It can be understood that in order to ensure the use state of the elastic member 1100, oil is provided in the mounting hole 240. Since the mounting hole 240 and the connecting portion 230 are separately arranged, the oil in the mounting hole 240 will not enter the connecting portion 230. Similarly, the low-pressure gas at the mounting hole 240 will not enter the connecting portion 230. In this way, the balance and controllability of the force acting on the slide 1000 in the slide groove 220 through the connecting portion 230 can be ensured, providing effective and reliable structural support for balancing the pressure of the front and rear ends of the slide 1000 close to the exhaust side of the working chamber 210.

[0119] In some embodiments, optionally, Fig.12 and Fig.19 As shown, the communication portion 230 includes a sink 232 .

[0120] The minimum distance from any point on the notch of the sink 232 to the center 250 of the cylinder is denoted as L1.

[0121] The maximum distance from any point on the notch of the sink 232 to the center 250 of the cylinder is recorded as L2.

[0122] The maximum distance from any point on the wall of the sink 232 to the center 250 of the cylinder is recorded as L3.

[0123] The inner diameter of the cylinder 200 is denoted by D.

[0124] The eccentricity of the crankshaft 900 of the compressor 10 is represented by e.

[0125] The length of the slide 1000 is denoted by L.

[0126] Among them, D / 2<L1<(D / 2)+L-2×e, and L2<L3.

[0127] In this embodiment, the matching structure of the communication portion 230 , the cylinder 200 , the crankshaft 900 of the compressor 10 , and the sliding vane 1000 is defined.

[0128] The connecting portion 230 includes a sink groove 232 , the sink groove 232 is connected to a side of the vane groove 220 close to the exhaust side, and the sink groove 232 is connected to the first channel 310 .

[0129] The sink 232 has a notch. The minimum distance from any point on the notch of the sink 232 to the center 250 of the cylinder is defined as L1. The maximum distance from any point on the notch of the sink 232 to the center 250 of the cylinder is defined as L2. The maximum distance from any point on the groove wall of the sink 232 to the center 250 of the cylinder is defined as L3. It can be understood that the groove wall of the sink 232 refers to the rest of the sink 232 excluding the notch.

[0130] The inner diameter of the cylinder 200 is defined as D, the eccentricity of the crankshaft 900 of the compressor 10 is defined as e, and the length of the vane 1000 is defined as L.

[0131] The relationship between L1, L2, L3, D, e and L is defined to satisfy D / 2<L1<(D / 2)+L-2×e, and L2<L3, that is, the matching structure of the cylinder center 250, the sink groove 232, the crankshaft 900 and the slide 1000 is defined. In this way, while ensuring the effectiveness and feasibility of the slide 1000 sliding relative to the slide groove 220, the airtightness of the sink groove 232 can be ensured to avoid air leakage, and low-pressure gas can be prevented from entering the sink groove 232, resulting in uneven force on the slide 1000 and deflection relative to the slide groove 220, thereby providing effective and reliable structural support for reducing the friction between the slide 1000 and the groove wall of the slide groove 220.

[0132] In some embodiments, optionally, Figure 1 , Fig. 9 , Fig.10 , Fig.19 and Fig. 22 As shown, the bearing assembly 300 includes a first bearing 320 and a second bearing 330 .

[0133] The cylinder 200 is located between the first bearing 320 and the second bearing 330 .

[0134] At least one of the first bearing 320 and the second bearing 330 is provided with a first passage 310 .

[0135] In this embodiment, the structure of the bearing assembly 300 is defined. Optionally, the bearing assembly 300 includes a first bearing 320 and a second bearing 330 , and the cylinder 200 is located between the first bearing 320 and the second bearing 330 .

[0136] At least one of the first bearing 320 and the second bearing 330 is provided with the first passage 310, that is, the first bearing 320 is provided with the first passage 310, or the second bearing 330 is provided with the first passage 310, or the first bearing 320 and the second bearing 330 are both provided with the first passage 310. In other words, at least one of the first bearing 320 and the second bearing 330 serves as a mounting carrier of the first passage 310, so as to ensure that the high-pressure gas of the muffler 400 can flow to the sliding vane groove 220 through the first passage 310 and the connecting portion 230.

[0137] Optionally, when the compressor 10 is working, the high-pressure refrigerant in the cylinder 200 flows to the exhaust port of the shell 100 through the exhaust passage of the bearing assembly 300, and then flows into the condenser through the exhaust port.

[0138] In some embodiments, optionally, Figure 1 , Fig.10 and Fig.19 As shown, when the number of the cylinder 200 is one, the first bearing 320 is provided with the first passage 310 .

[0139] The first bearing 320 is located at a side of the cylinder 200 facing the motor 500 of the compressor 10 .

[0140] In this embodiment, when the number of the cylinder 200 is one, the cylinder 200 is located between the first bearing 320 and the second bearing 330 .

[0141] The compressor 10 further includes a motor 500, and the first bearing 320 is located on the side of the motor 500 of the cylinder 200 facing the compressor 10, that is, the distance from the first bearing 320 to the motor 500 is smaller than the distance from the second bearing 330 to the motor 500. It can also be said that the first bearing 320 is located between the motor 500 and the cylinder 200.

[0142] The first bearing 320 closer to the motor 500 serves as a mounting carrier of the first channel 310 to ensure the communication between the vane slot 220 and the high-pressure chamber 410 of the muffler 400 .

[0143] In some other embodiments, when the number of the cylinder 200 is one, the second bearing 330 is provided with the first passage 310 , and the second bearing 330 is located at a side of the cylinder 200 away from the motor 500 of the compressor 10 .

[0144] Alternatively, if Figure 1 As shown, the motor 500 includes a stator 510 and a rotor 520 .

[0145] In some embodiments, optionally, Fig. 22 As shown, when the number of the cylinders 200 is plural, the compressor 10 further includes a partition plate 600 .

[0146] The partition plate 600 is located between the first bearing 320 and the second bearing 330 .

[0147] Each cylinder 200 is connected to a partition plate 600 .

[0148] The partition plate 600 is provided with a second passage 610 .

[0149] The communication portion 230 and the first passage 310 are communicated with each other through the second passage 610 .

[0150] The first bearing 320 and the second bearing 330 are both provided with a first passage 310 .

[0151] In this embodiment, when the number of the cylinders 200 is plural, the compressor 10 further includes a partition plate 600, and the partition plate 600 is located between the first bearing 320 and the second bearing 330. Any cylinder 200 of the plurality of cylinders 200 is connected to the partition plate 600.

[0152] The partition plate 600 is provided with a second channel 610 , the second channel 610 is communicated with the communication portion 230 , and the second channel 610 is communicated with the first channel 310 . That is, the communication portion 230 and the first channel 310 are communicated through the second channel 610 .

[0153] The first bearing 320 is provided with a first passage 310, and the second bearing 330 is provided with a second passage 310. This arrangement can meet the use requirement of connecting the vane groove 220 of any cylinder 200 in the plurality of cylinders 200 with the high pressure chamber 410 of the muffler 400.

[0154] Optionally, the partition 600 is provided with a first air intake port and an air intake passage, each cylinder 200 is provided with a second air intake port, and the shell 100 is provided with a first opening 340 and a second opening 350.

The condenser is connected between the compressor 10 and the expansion device, the evaporator is connected between the expansion device and the liquid reservoir, the liquid reservoir is connected to the first opening 340 and the plurality of second openings 350, the first air intake port is communicated with the first opening 340 through the first air intake pipe, and each second air intake port is communicated with a second opening 350 through the first second air intake pipe.

[0155] The high-pressure refrigerant flowing out of the compressor 10 flows to the condenser and becomes liquid refrigerant. Then, the high-pressure liquid refrigerant passes through the expansion device and becomes low-pressure evaporative refrigerant under the action of the evaporator. The low-pressure refrigerant after flowing through the liquid storage tank then flows into the compressor 10 through the first intake pipe and multiple second intake pipes.

[0156] The low-pressure refrigerant of the liquid accumulator can enter the compressor 10 through the first air inlet of the partition 600 and the second air inlet of the multiple cylinders 200 at the same time, and the low-pressure refrigerant in the air inlet channel of the partition 600 will flow to the compression chambers of the multiple cylinders 200. Compared with the low-pressure refrigerant of the liquid accumulator only entering the respective compression chambers through the air inlet of the multiple cylinders 200, this arrangement increases the amount of refrigerant sucked into the compression chambers of the multiple cylinders 200 without changing the existing structure of the cylinders 200, thereby increasing the volumetric efficiency of the compressor 10, which is conducive to improving the performance and market competitiveness of the compressor 10.

[0157] It is understandable that, since the compression chambers of the plurality of cylinders 200 are connected to the intake passage, the refrigerant in the intake passage of the partition 600 can flow to the compression chamber of each cylinder 200 to increase the volumetric efficiency of the compressor 10 .

[0158] Optionally, when the number of cylinders 200 is two, the connecting portion 230 of one cylinder 200 and the first channel 310 of the first bearing 320 are connected through the second channel 610 of the partition 600, and the connecting portion 230 of the other cylinder 200 and the first channel 310 of the second bearing 330 are connected through the second channel 610 of the partition 600.

[0160] The first bearing 320 section is connected to the circumferential side of the second bearing 330 section.

[0161] Along the height direction of the compressor 10 , the thickness of the first bearing 320 section is smaller than the thickness of the second bearing 330 section.

[0162] At least one of the first bearing 320 section of the first bearing 320 and the first bearing 320 section of the second bearing 330 is provided with a first passage 310 .

[0163] In this embodiment, the structures of the first bearing 320 and the second bearing 330 are further defined.

[0164] The first bearing 320 includes a first bearing 320 section and a second bearing 330 section, and the first bearing 320 section is connected to the circumferential side of the second bearing 330 section.

[0165] The second bearing 330 includes a first bearing 320 segment and a second bearing 330 segment, and the first bearing 320 segment is connected to the circumferential side of the second bearing 330 segment.

[0166] At least one of the first bearing 320 section of the first bearing 320 and the first bearing 320 section of the second bearing 330 is provided with the first channel 310.

In other words, the first channel 310 is provided on the thinner portion of the first bearing 320 and the second bearing 330. In this way, the processing difficulty of the first channel 310 can be reduced, the processing technology of the first channel 310 can be simplified, which is conducive to improving the processing efficiency of the first channel 310, and further conducive to reducing the production cost of the product.

[0167] Optionally, any one of the first bearing 320 and the second bearing 330 is provided with a recessed portion, the recessed portion forms a section of the first bearing 320 , and a portion of a peripheral side of the recessed portion forms a section of the second bearing 330 .

[0168] In some embodiments, optionally, Fig. 9 , Fig.10 , Fig.17 and Fig. 22 As shown, the cylinder 200 or the bearing assembly 300 is provided with a guide groove 700 .

[0169] The communication portion 230 and the first channel 310 are communicated with each other through the guide groove 700 .

[0170] In this embodiment, when the distance between the connecting portion 230 and the first channel 310 is far, that is, the first channel 310 and the connecting portion 230 cannot be directly connected, the guide groove 700 can be provided in the cylinder 200 or in the bearing assembly 300, and the guide groove 700 can be used to connect the first channel 310 and the connecting portion 230. That is, the connecting portion 230 and the first channel 310 are connected through the guide groove 700.

[0171] This arrangement reasonably utilizes the existing structure of the cylinder 200 and the bearing assembly 300, so that when the connecting portion 230 and the first channel 310 cannot be directly connected, the purpose of connecting the first channel 310 and the connecting portion 230 can be achieved through the guide groove 700 on the cylinder 200 or the bearing assembly 300. This arrangement is processable and avoids investing in additional devices to connect the first channel 310 and the connecting portion 230, which is conducive to reducing the production cost of the compressor 10.

[0172] Optionally, the outer surface of the cylinder 200 is provided with a guide groove 700, and / or the outer surface of the bearing assembly 300 is provided with a guide groove 700.

[0174] In this embodiment, the extending direction of the first passage 310 is further defined. Specifically, the first passage 310 extends along the height direction of the compressor 10.

[0175] It can be understood that, along the height direction of the compressor 10 , the first bearing 320 has a first end surface and a second end surface that are opposite and spaced apart, and the first passage 310 passes through the first end surface and the second end surface.

[0177] In some embodiments, optionally, Fig.15 As shown, a first opening 340 is defined in a side wall of the bearing assembly 300 .

[0178] The axial end surface of the bearing assembly 300 is provided with a second opening 350 .

[0179] The first passage 310 connects the first opening 340 and the second opening 350 .

[0180] In this embodiment, the extension direction of the first channel 310 is further defined. Specifically, the first channel 310 is arranged in a curved manner, such as the first channel 310 is arranged in an "L" shape. For example, the first channel 310 is arranged in an "S" shape, etc., which are not listed here one by one.

[0181] Optionally, the bearing assembly 300 has a side wall and an axial end surface. The side wall of the bearing assembly 300 is provided with a first opening 340 , the axial end surface of the bearing assembly 300 is provided with a second opening 350 , and the first channel 310 connects the first opening 340 and the second opening 350 .

[0182] For example, the first bearing 320 has a side wall and an axial end surface. The side wall of the first bearing 320 is provided with a first opening 340 , the axial end surface of the first bearing 320 is provided with a second opening 350 , and the first channel 310 connects the first opening 340 and the second opening 350 .

[0184] In some embodiments, optionally, on a cross section of the first channel 310 , a maximum distance between any two points of the first channel 310 is recorded as d.

[0185] Among them, d≥1mm.

[0186] In this embodiment, the structure of the first channel 310 is further defined, so that the first channel 310 is sectioned along the length direction perpendicular to the first channel 310, and the section is the cross section of the first channel 310. The maximum distance between any two points on the cross section is d, where d≥1mm. This setting can ensure the flow rate of the first channel 310, and can ensure the amount of high-pressure gas entering the slide groove 220 per unit time, and provide effective and reliable structural support for balancing the pressure of the front and rear ends of the exhaust side of the slide 1000 close to the working chamber 210.

[0187] Optionally, d=1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, etc., which are not listed here one by one.

[0188] A refrigeration device according to some embodiments of the present application includes: a compressor 10 as in the above embodiment.

[0189] In this embodiment, the refrigeration device comprises a compressor 10 .

[0190] The compressor 10 includes a housing 100 , a cylinder 200 , a bearing assembly 300 , and a muffler 400 .

[0191] The cylinder 200, the bearing assembly 300 and the muffler 400 are all arranged in the shell 100, that is, the shell 100 serves as an installation carrier for the cylinder 200, the bearing assembly 300 and the muffler 400, has the function of installing and fixing the cylinder 200, the bearing assembly 300 and the muffler 400, and can ensure the matching dimensions of the cylinder 200, the bearing assembly 300 and the muffler 400.

[0192] Among them, the cylinder 200 is provided with a working chamber 210, a vane groove 220 and a connecting portion 230. The vane groove 220 is connected to the working chamber 210. The working chamber 210 has an intake side and an exhaust side. The connecting portion 230 is connected to the side of the vane groove 220 close to the exhaust side of the working chamber 210.

[0193] The bearing assembly 300 is provided with a first passage 310, which is communicated with the high pressure chamber 410 of the muffler 400 and the first passage 310 is communicated with the communication portion 230. That is, the communication portion 230 and the high pressure chamber 410 of the muffler 400 are communicated through the first passage 310.

[0194] It is understandable that the gas in the high-pressure chamber 410 of the muffler 400 flows to the first channel 310 through the exhaust hole of the muffler 400, flows to the connecting portion 230 through the first channel 310, and enters the vane slot 220 through the connecting portion 230. The gas entering the vane slot 220 through the connecting portion 230 acts on the vane 1000 in the vane slot 220 to balance the pressure of the front and rear ends of the vane 1000 close to the exhaust side of the working chamber 210, and inhibits the vane 1000 from rotating relative to the vane slot 220. In this way, the inclination angle of the vane 1000 in the vane slot 220 relative to the vane slot 220 can be reduced, and the probability of the vane 1000 contacting the slot wall of the vane slot 220 is reduced. The problem of vane tilt caused by the suction and exhaust pressure difference in the related art is solved, and the friction between the vane 1000 and the groove wall of the vane groove 220 is effectively reduced, which is beneficial to reducing wear and can improve the reliability of the use of the vane 1000, which is beneficial to improving the performance of the compressor 10.

[0195] This arrangement makes reasonable use of the existing structure of the compressor 10 (such as the muffler 400 and the bearing assembly 300). By providing the connecting portion 230 and the first channel 310, and making the first channel 310 connect the high-pressure chamber 410 of the muffler 400 and the connecting portion 230, a portion of the high-pressure gas of the muffler 400 can enter the vane groove 220 through the first channel 310 and the connecting portion 230, that is, the flow path of a portion of the high-pressure gas of the muffler 400 is changed, thereby balancing the consistency of the force on the exhaust side of the vane 1000 close to the working chamber 210, reducing the deflection angle of the vane 1000 relative to the vane groove 220, and reducing the contact stress and friction loss between the vane 1000 and the vane groove 220.

[0196] Optionally, the compressor 10 of the present application includes a rotary compressor. The compressor 10 includes a compression mechanism and a motor 500 disposed in a housing 100, and the compression mechanism includes a cylinder 200, a piston 800, a crankshaft 900, a bearing assembly 300, a sliding vane 1000 and a spring.

[0198] The piston 800 rotates eccentrically in the working chamber 210 of the cylinder 200. The crankshaft 900 is used to drive the piston 800 to rotate. The bearing assembly 300 includes a first bearing 320 and a second bearing 330, and the first bearing 320 and the second bearing 330 are used to support the crankshaft 900 and seal the working chamber 210 of the cylinder 200.

The sink 232 and the mounting hole 240 are not interpenetrating with each other, and the first bearing 320 and / or the second bearing 330 are provided with a first channel 310 penetrating the axial end surface of the bearing, one end of the first channel 310 is connected to the sink 232, and the other end of the first channel 310 is connected to the high-pressure chamber 410 of the muffler 400. After the high-pressure gas of the muffler 400 is discharged from the exhaust hole, it can flow from the first channel 310 to the sink 232 to balance the front and rear end pressures of the exhaust side of the vane 1000, which can effectively reduce the probability of the vane 1000 tilting due to the intake and exhaust pressure difference. The friction between the vane 1000 and the side wall of the vane slot 220 is effectively reduced, the wear is reduced, the reliability of the vane 1000 is improved, and the performance of the compressor 10 is improved.

[0201] The sink groove 232 and the mounting hole 240 are not connected, that is, the sink groove 232 and the mounting hole 240 are two relatively independent structures, and the sink groove 232 and the mounting hole 240 are not connected.

[0202] The minimum distance from any point on the slot of the groove 232 to the center 250 of the cylinder is recorded as L1, the maximum distance from any point on the slot of the groove 232 to the center 250 of the cylinder is recorded as L2, the maximum distance from any point on the groove wall of the groove 232 to the center 250 of the cylinder is recorded as L3, the inner diameter of the cylinder 200 is recorded as D, the eccentricity of the crankshaft 900 of the compressor 10 is recorded as e, and the length of the vane 1000 is recorded as L; wherein, D / 2<L1<(D / 2)+L-2×e, and L2<L3.

[0203] Optionally, the cross-section of the first channel 310 includes any one of the following shapes or a combination thereof: circular, elliptical, square and trapezoidal.
