Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] like Figures 1 to 6As shown in , an embodiment of the present invention provides a cylinder structure, which specifically includes a cylinder body 1, a through hole 14, a connecting groove 15 and a spring hole 17.

[0041] Specifically, Figure 1 and Figure 2 As shown in the figure, the cylinder body 1 is provided with a cylinder chamber 11 opened along the axial direction of the cylinder body 1, a blade groove 12 extending along the radial direction of the cylinder body 1 and connected to the cylinder chamber 11, and an intake channel 13 extending along the radial direction of the cylinder body 1 and connected to the cylinder chamber 11. The piston 2 is rotatably arranged in the cylinder chamber 11. The peripheral wall of the cylinder chamber 11 is provided with an exhaust port 16. The blade 3 is movably arranged in the blade groove 12. The blade groove 12 includes a first end close to the cylinder chamber 11 and a second end away from the cylinder chamber 11. Along the circumferential direction of the cylinder body 1, the blade groove 12 and the intake channel 13 are spaced apart. The end of the intake channel 13 away from the cylinder chamber 11 is used for arranging An intake pipe is installed; a through hole 14 is opened on the inner wall of the first end of the blade groove 12, and is arranged on the side of the cylinder body 1 away from the intake channel 13 along the circumferential direction of the cylinder body 1, the through hole 14 is connected with the first end of the blade groove 12, the through hole 14 extends along the axial direction of the cylinder body 1 and penetrates the cylinder body 1; one end of the connecting groove 15 is connected to the through hole 14, and the other end is connected to the exhaust port 16, and the extension direction of the connecting groove 15 is set at an acute angle to the extension direction of the blade groove 12, the spring hole 17 is opened in the cylinder body 1 along the radial direction of the cylinder body 1, and is connected with the blade groove 12, and along the axial direction of the cylinder body 1, the projection of the first end of the blade groove 12 does not coincide with the projection of the spring hole 17.

[0042] In detail, when working, Figure 1 and Figure 2 As shown in , when there is too much oil in the cylinder body 1, part of the oil can flow into the through hole 14 through the exhaust port 16 and the connecting groove 15. At this time, the through hole 14 and the connecting groove 15 are equivalent to an oil storage structure. Since the through hole 14 is connected to the high-pressure side of the blade groove 12, and the through hole 14 runs through the cylinder body 1, the contact area between the oil in the through hole 14 and the blade 3 is guaranteed. Therefore, the oil in the through hole 14 can fully lubricate the blade 3 and the high-pressure side of the blade groove 12, thereby effectively reducing the wear of the blade 3 and the high-pressure side of the blade groove 12; further, when there is excess liquid refrigerant in the cylinder body 1, it can also be stored in the through hole 14, so as to reduce the situation of exhaust liquid hitting the valve plate, thereby avoiding compression jamming and valve plate fatigue damage; in addition, the compressed refrigerant gas can enter the through hole 14 through the exhaust port 16 and the connecting groove 15. In this process, the sound waves are continuously reflected in the through hole 14, thereby playing a silencing role in reducing the exhaust noise.

[0043] In this embodiment, the lubrication effect of the high-pressure side of the blade groove 12 is improved by providing the through hole 14 and the connecting groove 15, thereby reducing the wear of the blade 3 and the high-pressure side of the blade groove 12, thereby extending the service life of the cylinder body 1; reducing the compression jamming and valve plate fatigue damage caused by the exhaust liquid hitting the valve plate; and reducing the exhaust noise.

[0044] Preferably, if Figure 2 and Figure 3 As shown in , the through hole 14 is a tapered hole, and the large end of the tapered hole is connected to one end of the connecting groove 15. By setting the through hole 14 as a tapered hole, the reflection of the sound wave in the through hole 14 can be increased, thereby further reducing the noise. Furthermore, the cone angle of the tapered hole is α, and the range of α is: greater than 0° and less than 45°. Specifically, a cylinder structure with tapered holes of different angles can be selected according to actual needs. For example, when the exhaust noise is large, a cylinder structure with a cone angle α of the tapered hole in the range of 30° to 45° can be selected. When the exhaust noise is small, a cylinder structure with a cone angle α of the tapered hole in the range of 10° to 20° can be selected.

[0045] Preferably, if Figure 2 and 4 As shown in , the angle between the extension direction of the connecting groove 15 and the extension direction of the blade groove 12 is β, and the range of β is: greater than 0° and less than 90°. In this way, it can ensure that the through hole 14 is opened at the first end of the blade groove 12 and is located on the high pressure side of one end of the blade groove 12.

[0046] Preferably, if Figure 2 and 4 As shown in FIG. 1 , along the axial direction of the cylinder body 1, the projection shape of the area enclosed by one end of the through hole 14 and one side of the blade slot 12 where the through hole 14 is located is an arcuate shape. In this way, the shape of the through hole 14 is similar to a resonance cavity, thereby increasing the reflection of sound waves and reducing noise. Specifically, the central angle of the arcuate shape is θ, and the range of θ is: 90° to 270°. Further preferably, as Figure 4 As shown in , θ is 180°. At this time, the arcuate shape is a "semicircular arc", and the contact surface between the through hole 14 and the blade 3 is the largest, so that the blade 3 and the blade groove 12 can be better lubricated, and the wear between the blade 3 and the high-pressure side of the blade groove 12 can be reduced. Of course, θ can also have other values, for example, Figure 5 As shown in , θ is 270°. At this time, the bow shape is a "superior arc bow", the through hole 14 is more circular, the reflection effect of the sound wave is better, the silencing effect is better, but the lubrication effect is worse than θ is 180°, and the manufacturing difficulty is high; for another example, Figure 6 As shown in , θ is 90°. At this time, the bow shape is a "bad arc bow" with low manufacturing difficulty, but the sound-absorbing effect is relatively poor.

[0047] In detail, the blade groove 12 is used to install the blade 3, and the first end of the blade groove 12 is the end close to the cylinder chamber 11. Along the axial direction of the cylinder body 1, the projection of the first end of the blade groove 12 does not coincide with the projection of the spring hole 17; the second end of the blade groove 12 is the end away from the cylinder chamber 11. Along the axial direction of the cylinder body 1, the projection of the second end of the blade groove 12 is located within the projection of the spring hole 17, and the second end of the blade groove 12 is connected to a through hole that passes through the cylinder body 1 along the axial direction of the cylinder body 1. The axial projection shape of the through hole in the cylinder body 1 is circular, and the through hole is used for processing the blade groove 12.

[0048] Preferably, the through hole 14 is formed on the inner wall of the first end of the blade slot 12 , and along the axial direction of the cylinder body 1 , the projection of the through hole 14 does not overlap with the projection of the spring hole 17 .

[0049] like Figure 1 and Figure 2 As shown, an embodiment of the present invention further provides a horizontal rotor compressor, including a housing, and a motor, a piston 2, a crankshaft 4, a first cylinder end cover 51, a second cylinder end cover 52, a blade 3, a spring, and the above-mentioned cylinder structure arranged inside the housing. Specifically, along the axial direction of the cylinder body 1, the first cylinder end cover 51 and the second cylinder end cover 52 are detachably mounted on both ends of the cylinder body 1, the first cylinder end cover 51 and the second cylinder end cover 52 can close both ends of the through hole 14, the first cylinder end cover 51 and the second cylinder end cover 52 are both provided with shaft holes, the crankshaft 4 is passed through the two shaft holes and the piston 2 and is transmission-connected with the output end of the motor, the spring is arranged in the spring hole 17, and one end of the spring abuts against the blade 3, and the other end abuts against the inner wall of the housing. In detail, when the horizontal rotor compressor is working, the motor drives the crankshaft 4 to rotate, and the crankshaft 4 drives the piston 2 to rotate eccentrically. The gaseous refrigerant enters the cylinder chamber 11 through the intake pipe and the intake channel 13, and is continuously compressed to a certain pressure, and then discharged through the exhaust valve of the first cylinder end cover 51. During the rotation of the piston 2, the elastic restoring force of the spring can drive the blade 3 to press against the piston 2.

[0050] By applying the above-mentioned cylinder structure to the horizontal rotor compressor, the lubrication effect of the high-pressure side of the blade 3 and the blade slot 12 in the horizontal rotor compressor is improved, and the wear between the blade 3 and the high-pressure side of the blade slot 12 is reduced, which can effectively extend the service life of the horizontal rotor compressor; it can reduce the risk of liquid hitting the valve plate when the horizontal rotor compressor is running, reduce the operating power of the compressor, and avoid compression jamming and valve plate fatigue damage; in addition, it can also reduce the noise of the horizontal rotor compressor during operation.

[0051] Specifically, along the circumference of the cylinder body 1, the cylinder body 1 is provided with a first fixing hole 18 extending along the axial direction of the cylinder body 1, and the first cylinder end cover 51 and the second cylinder end cover 52 are both provided with a second fixing hole matching the first fixing hole 18, and the fasteners detachably connect the first cylinder end cover 51, the cylinder body 1, and the second cylinder end cover 52 through the first fixing hole 18 and the second fixing hole. Such a configuration facilitates the disassembly and assembly between the first cylinder end cover 51, the cylinder body 1, and the second cylinder end cover 52.
