Description

TECHNICAL FIELD

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

[0002] To meet the energy saving requirements, the energy efficiency level of the refrigeration equipment is further improved, and the efficiency requirement of the compressor is also higher and higher. In the rotary compressor, the friction power consumption accounts for about 8% of the total power consumption, and improving the friction power consumption has a great effect on the efficiency improvement of the compressor. Among them, the wear between the sliding vane and the sliding vane groove accounts for about 20% of the entire friction power consumption.

[0003] In the related art, the head of the sliding vane presses against the outer circle of the piston to divide the compression chamber of the cylinder into a suction chamber and a discharge chamber. The rotation of the crankshaft can drive the piston to rotate. When the piston rotates, the gas is sucked from the suction chamber and discharged from the compression chamber after being compressed.

[0004] During the operation of the compressor, the suction chamber and the discharge chamber form a high-pressure area and a low-pressure area. Under the action of the pressure difference, the head of the sliding vane tilts towards the suction chamber, and the tail of the sliding vane tilts towards the discharge chamber. During the reciprocating motion of the sliding vane, the friction between the sliding vane and the wall surface of the sliding vane groove increases due to the tilting of the sliding vane, causing wear of the parts and increasing the friction power consumption of the compressor, resulting in a decrease in the performance of the compressor. SUMMARY

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

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

[0007] The second aspect of the present application provides a refrigeration equipment.

[0008] Therefore, the first aspect of the present application provides a compressor, which comprises a shell, a cylinder, a bearing assembly and a silencer.

[0009] The compressor provided by the present application comprises a shell, a cylinder, a bearing assembly and a silencer.

[0010] The cylinder, the bearing assembly and the silencer are all arranged in the shell, that is, the shell serves as a mounting carrier for the cylinder, the bearing assembly and the silencer, has the functions of mounting and fixing the cylinder, the bearing assembly and the silencer, and can ensure the cooperation size of the cylinder, the bearing assembly and the silencer.

[0011] The cylinder is provided with a working chamber, a sliding vane groove and a communication part. The sliding vane groove is in communication with the working chamber. The working chamber has an air suction side and an air exhaust side. The communication part is in communication with one side of the sliding vane groove close to the air exhaust side of the working chamber.

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

[0013] It can be understood 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 communication part through the first channel, and enters the sliding vane groove through the communication part. The gas entering the sliding vane groove through the communication part acts on the sliding vane in the sliding vane groove to balance the pressure of the front and rear ends of the sliding vane close to the air exhaust side of the working chamber, and to inhibit the rotation of the sliding vane relative to the sliding vane groove. In this way, the inclination angle of the sliding vane in the sliding vane groove relative to the sliding vane groove can be reduced, and the probability of the sliding vane contacting the groove wall of the sliding vane groove can be reduced. The problem of the inclination of the sliding vane caused by the pressure difference between air suction and air exhaust in the related art is solved, the friction between the sliding vane and the groove wall of the sliding vane groove is effectively reduced, the abrasion is reduced, the reliability of the sliding vane in use is improved, and the use performance of the compressor is improved.

[0014] The existing structure of the compressor (such as the muffler and the bearing assembly) is reasonably utilized. The communication part and the first channel are arranged, and the first channel is arranged to communicate the high-pressure chamber of the muffler and the communication part. Thus, a part of the high-pressure gas of the muffler can enter the sliding vane groove through the first channel and the communication part. That is, the flow path of a part of the high-pressure gas of the muffler is changed. Thus, the consistency of the force acting on the sliding vane close to the air exhaust side of the working chamber can be balanced, the deflection angle of the sliding vane relative to the sliding vane groove can be reduced, and the contact stress and friction loss of the sliding vane and the sliding vane groove can be reduced.

[0015] According to the compressor provided in the application, the following additional technical features can be further provided.

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

That is, the sliding vane is in sliding connection with the sliding vane groove, and the sliding vane can reciprocate relative to the sliding vane groove under the driving of the piston.

[0018] The cylinder is further provided with a mounting hole. The compressor further includes an elastic member arranged in the mounting hole. The mounting hole has the function of mounting and fixing the elastic member, and provides effective and reliable structural support for ensuring the cooperation size of the elastic member and the sliding vane. The elastic member is connected with the sliding vane, and provides elastic force for the sliding vane when the sliding vane moves relative to the sliding vane groove, so as to reset the sliding vane.

[0019] Optionally, the elastic member comprises a spring, a tension spring, etc.

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

[0021] In this embodiment, the communication portion and the mounting hole are arranged separately by defining the matching structure of the communication portion and the mounting hole, i.e., the communication portion and the mounting hole are two relatively independent structures, in other words, the communication portion and the mounting hole are not communicated with each other.

[0022] It can be understood that, in order to ensure the use state of the elastic member, oil is arranged in the mounting hole, and since the mounting hole is arranged separately from the communication portion, the oil in the mounting hole will not enter the communication portion, and similarly, low-pressure gas at the mounting hole will not enter the communication portion, so that the balance and controllability of the force acting on the sliding vane in the sliding vane groove through the communication portion can be ensured, and effective and reliable structural support is provided for balancing the pressure of the front and rear ends of the sliding vane close to the exhaust side of the working chamber.

[0023] In some embodiments, the communication portion comprises a sink groove; the minimum distance from any point on the slot opening of the sink groove to the center of the cylinder is denoted as L1, the maximum distance from any point on the slot opening of the sink groove to the center of the cylinder is denoted as L2, the maximum distance from any point on the slot wall of the sink groove to the center of the cylinder is denoted as L3, the inner diameter of the cylinder is denoted as D, the eccentricity of the crankshaft of the compressor is denoted as e, and the length of the sliding vane is denoted as L; wherein D / 2

[0026] The sink groove has a slot opening. The minimum distance from any point on the slot opening of the sink groove to the center of the cylinder is denoted as L1. The maximum distance from any point on the slot opening of the sink groove to the center of the cylinder is denoted as L2. The maximum distance from any point on the slot wall of the sink groove to the center of the cylinder is denoted as L3, and it can be understood that the slot wall of the sink groove refers to the remaining part of the sink groove excluding the slot opening.

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

[0028] And the relationship of L1, L2, L3, D, e and L is defined to satisfy D / 2

[0029] In some embodiments, optionally, the bearing assembly comprises: 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 the first channel.

[0030] In this embodiment, the structure of the bearing assembly is defined, and the bearing assembly comprises 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 the 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. That is to say, at least one of the first bearing and the second bearing serves as a mounting carrier of the first channel. In order to ensure that the high-pressure gas of the muffler can flow to the slide groove through the first channel and the communication part.

[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 cylinders is one, the first bearing is provided with the first channel, and the first bearing is located on the side of the cylinder facing the motor of the compressor.

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

[0035] In this embodiment, the compressor further comprises a motor, and the first bearing is located on the side of the cylinder facing the motor of the compressor, that is, the distance from the first bearing to the motor is less than the distance from the second bearing to the motor. In other words, the first bearing is located between the motor and the cylinder.

[0036] The first bearing close to the motor serves as a mounting carrier of the first channel to ensure the communication between the slide groove and the high-pressure cavity of the muffler.

[0037] In some embodiments, when the number of cylinders is multiple, the compressor further comprises a partition plate located between the first bearing and the second bearing, each cylinder is connected with the partition plate, the partition plate is provided with a second channel, the communication part and the first channel are communicated through the second channel; the first bearing and the second bearing are both provided with the first channel.

[0038] In this embodiment, when the number of cylinders is multiple, the compressor further comprises a partition plate located between the first bearing and the second bearing. Any cylinder in the multiple cylinders is connected with the partition plate.

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

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

[0041] Optionally, the partition plate is provided with a first suction port and a suction channel, each cylinder is provided with a second suction port, the shell is provided with a first opening and a plurality of second openings. The refrigeration equipment further comprises a condenser, an expansion device, an evaporator, a liquid accumulator, the compressor, a first suction pipe and a plurality of second suction pipes. The condenser is connected between the compressor and the expansion device, the evaporator is connected between the expansion device and the liquid accumulator, the liquid accumulator is connected with the first opening and the plurality of second openings, the first suction port is communicated with the first opening through the first suction pipe, and each second suction port is communicated with one second opening through a first second suction pipe.

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

[0043] The low-pressure refrigerant of the liquid accumulator can enter the compressor through the first suction port of the partition plate and the second suction ports of the plurality of cylinders at the same time, and the low-pressure refrigerant in the suction channel of the partition plate will flow to the compression cavities of the plurality of cylinders. Compared with the low-pressure refrigerant of the liquid accumulator entering the compression cavities of the plurality of cylinders respectively through the suction ports of the plurality of cylinders, this arrangement increases the amount of refrigerant sucked into the compression cavities of the plurality of cylinders without changing the existing structure of the cylinders, thereby increasing the volumetric efficiency of the compressor, which is conducive to improving the use performance and market competitiveness of the compressor.

[0044] It can be understood that, since the compression cavities of the plurality of cylinders are all communicated with the suction channel, the refrigerant in the suction channel of the partition plate can flow to the compression cavities of each cylinder to increase the volumetric efficiency of the compressor.

[0045] In some embodiments, optionally, the first bearing and the second bearing each comprise a first bearing segment and a second bearing segment, the first bearing segment is connected to the circumferential side of the second bearing segment; the thickness of the first bearing segment in the height direction of the compressor 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 the first channel.

[0046] In this embodiment, the structure of the first bearing and the second bearing is further limited.

[0047] The first bearing comprises a first bearing segment and a second bearing segment, and the first bearing segment is connected to the circumferential side of the second bearing segment. The thickness of the first bearing segment in the height direction of the compressor is less than the thickness of the second bearing segment in the height direction of the compressor.

[0048] The second bearing comprises a first bearing segment and a second bearing segment, and the first bearing segment is connected to the circumferential side of the second bearing segment. The thickness of the first bearing segment in the height direction of the compressor is less than the thickness of the second bearing segment in the height direction of the compressor.

That is, the first bearing segment of the first bearing is provided with the first channel, or the first bearing segment of the second bearing is provided with the first channel, or both the first bearing segment of the first bearing and the first bearing segment of the second bearing are provided with the first channel. That is, the first channel is arranged on the thinner part of the first bearing and the second bearing. In this way, the machining difficulty of the first channel can be reduced, the machining process of the first channel is simplified, the machining efficiency of the first channel is improved, and the production cost of the product is reduced.

[0050] In some embodiments, optionally, the cylinder or the bearing assembly is provided with a flow guide groove, and the communication part and the first channel are communicated through the flow guide groove.

[0051] In this embodiment, when the communication part and the first channel are far away, that is, the first channel and the communication part cannot be directly communicated, a flow guide groove can be arranged on the cylinder or the bearing assembly to communicate the first channel and the communication part through the flow guide groove. That is, the communication part and the first channel are communicated through the flow guide groove.

[0052] This arrangement reasonably utilizes the existing structure of the cylinder and the bearing assembly, so that when the communication part and the first channel cannot be directly communicated, the flow guide groove on the cylinder or the bearing assembly can be used to achieve the purpose of communicating the first channel and the communication part. This arrangement has machining feasibility, avoids the need to invest additional devices to communicate the first channel and the communication part, and helps to reduce the production cost of the compressor.

[0053] In some embodiments, optionally, the first channel extends in the 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.

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

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

[0095] The following description refers to the accompanying drawings and specific embodiments. Figures 1 to 22 A compressor 10 and a refrigeration device according to some embodiments of the present application.

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

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

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

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

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

[0101] The communication part 230 is in communication with a side of the sliding vane groove 220 close to the air exhaust side.

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

[0103] The muffler 400 is arranged in the housing 100, and the muffler 400 is provided with a high-pressure chamber 410, and the first channel 310 is in communication with the communication part 230 and the high-pressure chamber 410.

The elastic member 1100 is connected with the sliding vane 1000, and provides elastic force for the sliding vane 1000 when the sliding vane 1000 moves relative to the sliding vane groove 220, so as to reset the sliding vane 1000.

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

[0116] In some embodiments, optionally, as shown in Figure 2 , Figure 5 and Figure 7 , the communication part 230 and the mounting hole 240 are arranged separately.

[0117] In this embodiment, by defining the matching structure of the communication part 230 and the mounting hole 240, the communication part 230 and the mounting hole 240 are arranged separately, i.e., the communication part 230 and the mounting hole 240 are two relatively independent structures, in other words, the communication part 230 and the mounting hole 240 are not in communication with each other.

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

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

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

[0124] The eccentricity of the crankshaft 900 of the compressor 10 is denoted as e.

[0125] The length of the sliding vane 1000 is denoted as L.

[0126] Wherein, D / 2 < L1 < (D / 2) + L - 2 x e, and L2 < L3.

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

[0130] Wherein, 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 sliding vane 1000 is defined as L.

[0131] And the relationship of L1, L2, L3, D, e, and L is defined to satisfy D / 2 < L1 < (D / 2) + L - 2 x e, and L2 < L3, that is, the matching structure of the center 250 of the cylinder, the sink groove 232, the crankshaft 900, and the sliding vane 1000 is defined. In this way, while ensuring the effectiveness and feasibility of the sliding of the sliding vane 1000 relative to the sliding vane groove 220, the air tightness at the sink groove 232 can be ensured to avoid air leakage, and the low-pressure gas can be prevented from entering the sink groove 232 to cause the sliding vane 1000 to deflect relative to the sliding vane groove 220 due to unbalanced force. An effective and reliable structural support is provided for reducing the friction between the sliding vane 1000 and the wall of the sliding vane groove 220.

[0190] The compressor 10 comprises a shell 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 a mounting carrier of the cylinder 200, the bearing assembly 300 and the muffler 400, has the effect of mounting and fixing the cylinder 200, the bearing assembly 300 and the muffler 400, and can ensure the cooperation size of the cylinder 200, the bearing assembly 300 and the muffler 400.

One end of the first passage 310 is in communication with the sink groove 232, and the other end of the first passage 310 is in communication with the high-pressure chamber 410 of the muffler 400. The high-pressure gas of the muffler 400 can flow from the first passage 310 into the sink groove 232 after being discharged from the discharge hole, so as to balance the front and rear end pressures of the discharge side of the vane 1000, effectively reducing the probability of the vane 1000 tilting caused by the pressure difference between suction and discharge.
