Description

[0002] As society progresses, people have increasingly higher demands for refrigerators, and the compressor, as the core component of a refrigerator, also faces higher cooling requirements. Currently, commonly used suction valve plates and valve assemblies have only one exhaust port. On the one hand, this results in greater exhaust resistance and lower exhaust efficiency, affecting performance. On the other hand, the compressor's exhaust time is relatively short, and the excessively high impact speed of the exhaust valve plate can cause it to vibrate, generating aerodynamic noise and leading to wear and tear on components, thus reducing the compressor's lifespan.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The valve assembly component 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the valve assembly component 100 according to an embodiment of the present invention includes a valve plate 1 and an exhaust valve plate 2.

[0039] Specifically, valve assembly 100 is used in the compressor, such as Figure 1 and Figure 3 As shown, the valve plate 1 has two exhaust holes 111, and the exhaust valve plate 2 is located in the thickness direction of the valve plate 1 (e.g., Figure 1On one side of the third direction shown, the exhaust valve plate 2 includes an assembly part 21 and two exhaust parts 22. The two exhaust parts 22 are respectively arranged opposite to the two exhaust holes 111 for opening or closing the exhaust holes 111.

[0040] It is understandable that the exhaust valve plate 2 is a spring plate with a certain elasticity. The valve plate 1 and the exhaust valve plate 2 together define the exhaust valve. When the piston of the compressor moves upward, the exhaust part 22 opens the exhaust port 111 to discharge the compressed high-temperature and high-pressure refrigerant from the cylinder.

[0041] Furthermore, by providing two exhaust ports 111, the exhaust speed can be effectively accelerated and the exhaust efficiency improved. The exhaust valve plate 2 includes an assembly part 21 and two exhaust parts 22. The two exhaust parts 22 are respectively arranged opposite to the two exhaust ports 111, which reduces the impact speed of the exhaust valve plate 2, avoids the exhaust parts 22 continuously hitting the valve plate 1 at high frequency, avoids the exhaust valve plate 2 from vibrating, avoids the generation of aerodynamic noise, and at the same time avoids the wear of the exhaust valve plate 2, thus improving the service life of the compressor.

[0042] The direction of the line connecting the center points of the two exhaust holes 111 is the first direction (e.g., Figure 1 As shown in the first direction, along the first direction, the assembly part 21 is located between the two exhaust holes 111 and is fixedly connected to the valve plate 1, and the two exhaust parts 22 are located at both ends of the assembly part 21 along the first direction and are connected to the assembly part 21, making the assembly process of the exhaust valve plate 2 and the valve plate 1 simpler and more convenient.

[0043] According to the valve assembly component 100 of the present invention, by providing two exhaust holes 111 on the valve plate 1, the exhaust speed can be effectively accelerated and the exhaust efficiency improved. The exhaust valve plate 2 includes an assembly part 21 and two exhaust parts 22. The two exhaust parts 22 are respectively disposed opposite to the two exhaust holes 111, which reduces the impact speed of the exhaust valve plate 2, avoids the exhaust parts 22 continuously impacting the valve plate 1 at a high frequency, avoids damage to the exhaust valve plate 2, and improves the service life of the compressor. At the same time, the assembly part 21 is disposed between the two exhaust holes 111 and fixedly connected to the valve plate 1, and the two exhaust parts 22 are disposed at both ends of the assembly part 21 along the first direction and connected to the assembly part 21. The two exhaust parts 22 are respectively disposed opposite to the two exhaust holes 111 and are used to open or close the exhaust holes 111, making the assembly process of the exhaust valve plate 2 and the valve plate 1 simpler and more convenient.

[0044] In some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the assembly part 21 and the two exhaust parts 22 are integrally formed. When the valve assembly component 100 is assembled, the exhaust valve plate 2 and the valve plate 1 can be assembled simply by assembling the assembly part 21 with the valve plate 1, which simplifies the assembly process of the valve assembly component 100 and reduces the manufacturing cost of the valve assembly component 100.

[0045] In some embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the valve assembly 100 also includes a lift limiter 3, which is located on the side of the exhaust valve plate 2 away from the exhaust port 111 in the thickness direction. When the compressor is working, the exhaust valve plate 2 will open rapidly under the action of airflow. The exhaust valve plate 2 may over-open due to inertia or airflow impact, exceeding the elastic limit of the exhaust valve plate 2, resulting in deformation or breakage of the exhaust valve plate 2. At the same time, it may also prolong the return time of the exhaust valve plate 2 and delay the closing of the exhaust port 111, affecting the compression efficiency of the compressor. By setting the lift limiter 3, the exhaust valve plate 2 can be limited when the exhaust section 22 moves in the direction away from the exhaust port 111, reducing the risk of breakage and deformation of the exhaust valve plate 2 and avoiding affecting the compression efficiency of the compressor.

[0046] The lift limiter 3 extends along a first direction and includes a mounting part 31 and two limiting arms 32. The mounting part 31 is opposite to the assembly part 21 and fixedly connected to the valve plate 1. The two limiting arms 32 are located at both ends of the mounting part 31 along the first direction and connected to the mounting part 31. The two limiting arms 32 are respectively opposite to the two exhaust ports 111. The exhaust part 22 is movably disposed between the valve plate 1 and the corresponding limiting arm 32. This allows the two limiting arms 32 to limit the two exhaust parts 22 respectively, thus reducing the risk of breakage and deformation of the two exhaust parts 22 and increasing the reliability of the compressor's compression efficiency.

[0047] In this embodiment, along the thickness direction of the valve plate 1, the gap between the limiting arm 32 and the exhaust hole 111 is greater than the gap between the mounting part 31 and the exhaust hole 111, so that the limiting arm 32 reserves enough space for the movement of the exhaust part 22, and avoids the exhaust of the exhaust hole 111 from being unsmooth.

[0048] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, a limiting groove 11 is provided at one end of the valve plate 1 in the thickness direction, and an exhaust hole 111 is provided on the bottom wall of the limiting groove 11. The exhaust valve plate 2 and the lift limiter 3 are both provided in the limiting groove 11.

[0049] It is understood that the compressor includes a cylinder and a cylinder head, and the valve assembly 100 is located between the cylinder and the cylinder head. By setting a limiting groove 11 in a section of the valve plate 1 in the thickness direction, and both the exhaust valve plate 2 and the lift limiter 3 are located in the limiting groove 11, the overall volume of the valve assembly 100 can be reduced and the adaptability of the valve assembly 100 can be increased.

[0050] In some embodiments of the present invention, such as Figure 1 and Figure 3As shown, the bottom wall of the limiting groove 11 is provided with a plurality of limiting protrusions 112, which are located between two exhaust holes 111. The plurality of limiting protrusions 112 include two sets of limiting protrusions 112, along the second direction (e.g. Figure 1 As shown in the second direction, two sets of limiting protrusions 112 are arranged opposite each other. Along the first direction, each set of limiting protrusions 112 includes two limiting protrusions 112 located on both sides of the assembly part 21. Along the first direction, the limiting protrusions 112 are interference-fitted with the assembly part 21. The first direction, the second direction, and the thickness direction of the valve plate 1 are perpendicular to each other. At this time, the limiting protrusions 112 can limit the assembly part 21 in both the second direction and the first direction, preventing the exhaust valve plate 2 from undergoing unnecessary displacement during operation, avoiding exhaust failure of the compressor, and increasing the reliability of the compressor.

[0051] In this invention, the shape of the limiting protrusion 112 is not restricted. On the projection of the valve plate 1 in the thickness direction, the limiting protrusion 112 can be square, fan-shaped or other shapes, as long as it does not interfere with the exhaust valve plate 2.

[0052] In some embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the mounting part 31 is provided with elastic arms 311 at both ends along the second direction. Along the second direction, each set of limiting protrusions 112 and limiting grooves 11 together define the mounting groove. The elastic arms 311 provided on the same side of the mounting part 31 along the second direction are interference-fitted with the side wall of the corresponding mounting groove. The assembly of the mounting part 31 and the limiting groove 11 is relatively simple and reliable.

[0053] In this embodiment, the mounting part 31 is also provided with limiting blocks 312 at both ends along the second direction. The limiting blocks 312 are located in the mounting groove. The limiting blocks 312 are provided with elastic arms 311 at both ends along the first direction. The elastic arms 311 and the limiting blocks 312 together limit the mounting part 31, so that the mounting part 31 and the valve plate 1 are more closely matched.

[0054] In some embodiments of the present invention, along the thickness direction of the valve plate 1, the end face of the limiting arm 32 away from the exhaust hole 111 does not extend beyond the end face of the valve plate 1 with the limiting groove 11, which can further reduce the overall volume of the valve assembly component 100 and increase the adaptability of the valve assembly component 100.

[0055] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the valve assembly 100 also includes an intake valve plate 4, which is located at the end of the valve plate 1 opposite to the exhaust valve plate 2 in the thickness direction. The valve plate 1 is provided with an intake hole 12. The intake valve plate 4 includes a valve plate body 41 and a valve tongue 42, which is used to open or close the intake hole 12.

[0056] It is understandable that the suction valve plate 4 is a spring plate with a certain elasticity. The valve plate 1 and the suction valve plate 4 together define the suction valve. When the piston of the compressor moves downward, the valve tongue 42 of the suction valve plate 4 automatically opens the suction port 12 under the action of the pressure difference inside and outside the cylinder, allowing the low-temperature and low-pressure gaseous refrigerant to enter the cylinder.

[0057] The valve body 41 is provided with a first mounting hole 46, the valve tongue 42 is provided in the first mounting hole 46 and one end of the valve tongue 42 in the length direction is connected to the hole wall of the first mounting hole 46, and the remaining part of the valve tongue 42 is provided with a valve gap 421 between it and the hole wall of the first mounting hole 46, so as to facilitate the movement of the valve tongue 42 and facilitate the switching of the valve tongue 42 between opening and closing the intake hole 12.

[0058] The valve body 41 is provided with two exhaust holes 44, which are respectively arranged opposite to the two exhaust holes 111 to avoid the valve body 41 affecting the compressor exhaust.

[0059] In this embodiment, as Figures 1-3 As shown, the valve plate 1 is provided with a first mounting hole 13, and the intake valve plate 4 is provided with a second mounting hole 45. The fastener passes through the second mounting hole 45 and the first mounting hole 13 and is fastened to the cylinder head to realize the assembly of the valve assembly component 100 with the cylinder head.

[0060] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the exhaust port 44 is connected to the valve gap 421, which can reduce the clearance during the compressor's exhaust process, thereby effectively increasing the exhaust volume. At the same time, it facilitates the one-time machining of the holes and gaps on the suction valve plate 4.

[0061] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the intake valve plate 4 also includes a fixing part 43. The valve tongue 42 is provided with a second mounting hole 47. The fixing part 43 is provided in the second mounting hole 47 and one end of the fixing part 43 in the length direction is connected to the hole wall of the second mounting hole 47. There is a gap between the fixing part 43 and the hole wall of the first mounting hole 46, so that the connection area between the valve tongue 42 and the valve plate body 41 is small, so that the resistance when the valve tongue 42 moves is small, and the efficiency of the valve tongue 42 in opening or closing the intake hole 12 is increased.

[0062] On the projection of the valve plate 1 in the thickness direction, the fixing part 43 is spaced apart from the suction hole 12 to avoid the fixing part 43 affecting the compressor exhaust.

[0063] Furthermore, under the test conditions of R600a refrigerant, compressor speed of 50Hz, suction pressure of 0.0511MPa, suction temperature of 45℃, discharge pressure of 0.5038MPa, and discharge temperature of 95.16℃, the simulation results of the prior art and the present invention are shown in Table 1:

[0064] Table 1 Comparison of simulation results between existing technologies and this embodiment.

[0065]

[0066] It can be seen that, compared with the prior art, this embodiment increases the cooling capacity by 1.53W and the COP (Coefficient of Performance) by 0.01, effectively improving the energy utilization efficiency of the compressor.

[0067] Meanwhile, under the above operating conditions, the maximum bending stress of the exhaust valve plate 2 decreased by 58.12 MPa, and the exhaust velocity decreased by 2.13 m / s.

[0068] The valve assembly component 100 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings. It is to be understood that the following description is merely exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0069] like Figure 1 As shown, the valve assembly 100 according to an embodiment of the present invention includes a valve plate 1, an exhaust valve plate 2, a lift limiter 3, and an intake valve plate 4.

[0070] Specifically, the valve assembly 100 is used in a compressor. The valve plate 1 has two exhaust ports 111. An exhaust valve plate 2 is located on one side of the valve plate 1 along its thickness. The exhaust valve plate 2 includes an assembly part 21 and two exhaust parts 22, which are respectively positioned opposite to the two exhaust ports 111 and are used to open or close the exhaust ports 111. The exhaust valve plate 2 is a spring plate with a certain elasticity. The valve plate 1 and the exhaust valve plate 2 together define the exhaust valve. When the compressor piston moves upward, the exhaust parts 22 open the exhaust ports 111, discharging the compressed high-temperature, high-pressure refrigerant from the cylinder. The line connecting the center points of the two exhaust ports 111 is a first direction. Along this first direction, the assembly part 21 is located between the two exhaust ports 111 and is fixedly connected to the valve plate 1. The two exhaust parts 22 are located at both ends of the assembly part 21 along the first direction and are connected to the assembly part 21, making the assembly process of the exhaust valve plate 2 and the valve plate 1 relatively simple and convenient. A limiting groove 11 is provided at one end of the valve plate 1 in the thickness direction, and an exhaust hole 111 is provided on the bottom wall of the limiting groove 11. The exhaust valve plate 2 and the lift limiter 3 are both provided in the limiting groove 11.

[0071] The assembly part 21 and the two exhaust parts 22 are integrally formed. When assembling the valve assembly component 100, the exhaust valve plate 2 and the valve plate 1 can be assembled simply by assembling the assembly part 21 with the valve plate 1, which simplifies the assembly process of the valve assembly component 100 and reduces the manufacturing cost of the valve assembly component 100.

[0072] The lift limiter 3 is located on the side of the exhaust valve plate 2 away from the exhaust hole 111 in the thickness direction. It can limit the exhaust valve plate 2 when the exhaust part 22 moves in the direction away from the exhaust hole 111, thereby reducing the risk of breakage and deformation of the exhaust valve plate 2 and avoiding affecting the compression efficiency of the compressor.

[0073] The lift limiter 3 extends along a first direction and includes a mounting part 31 and two limiting arms 32. The mounting part 31 is opposite to the assembly part 21 and fixedly connected to the valve plate 1. The two limiting arms 32 are located at both ends of the mounting part 31 along the first direction and connected to the mounting part 31. The two limiting arms 32 are respectively opposite to the two exhaust holes 111. The exhaust part 22 is movably disposed between the valve plate 1 and the corresponding limiting arm 32. Along the thickness direction of the valve plate 1, the gap between the limiting arm 32 and the exhaust hole 111 is larger than the gap between the mounting part 31 and the exhaust hole 111, so that the limiting arm 32 provides sufficient space for the movement of the exhaust part 22 and avoids unobstructed exhaust from the exhaust hole 111. The two limiting arms 32 limit the two exhaust parts 22 respectively, so that the risk of fracture and deformation of the two exhaust parts 22 is small, increasing the reliability of the compressor's compression efficiency.

[0074] The bottom wall of the limiting groove 11 is provided with multiple fan-shaped limiting protrusions 112. The limiting protrusions 112 include two sets of limiting protrusions 112. Along the second direction, the two sets of limiting protrusions 112 are arranged opposite each other. Along the first direction, each set of limiting protrusions 112 includes two limiting protrusions 112 located on both sides of the assembly part 21. Along the first direction, the limiting protrusions 112 are interference-fitted with the assembly part 21. The first direction, the second direction, and the thickness direction of the valve plate 1 are perpendicular to each other. At this time, the limiting protrusions 112 can limit the assembly part 21 in both the second and first directions, preventing the exhaust valve plate 2 from undergoing unnecessary displacement during operation, avoiding exhaust failure of the compressor, and increasing the reliability of the compressor.

[0075] The mounting part 31 is provided with elastic arms 311 and limiting blocks 312 at both ends along the second direction. Along the second direction, each set of limiting protrusions 112 and limiting grooves 11 together define the mounting groove. The elastic arms 311 on the same side of the mounting part 31 along the second direction are interference-fitted with the side wall of the corresponding mounting groove. The limiting blocks 312 are provided in the mounting groove. The limiting blocks 312 are provided with elastic arms 311 at both ends along the first direction. The elastic arms 311 and the limiting blocks 312 together limit the mounting part 31, so that the mounting part 31 and the valve plate 1 are more tightly fitted.

[0076] The end face of the limiting arm 32 away from the exhaust port 111 does not extend beyond the end face of the valve plate 1 with the limiting groove 11, which can further reduce the overall volume of the valve assembly 100 and increase the adaptability of the valve assembly 100.

[0077] The valve assembly 100 also includes an intake valve plate 4, which is located at the end of the valve plate 1 opposite to the exhaust valve plate 2 in the thickness direction. The valve plate 1 has an intake hole 12. The intake valve plate 4 includes a valve plate body 41 and a valve tongue 42, which is used to open or close the intake hole 12. The valve plate body 41 has a first mounting hole 46. The valve tongue 42 is located in the first mounting hole 46, and one end of the valve tongue 42 in the length direction is connected to the hole wall of the first mounting hole 46. A valve gap 421 is provided between the remaining part of the valve tongue 42 and the hole wall of the first mounting hole 46 to facilitate the movement of the valve tongue 42 and to facilitate the switching of the valve tongue 42 between opening and closing the intake hole 12. The valve plate body 41 has two exhaust through holes 44, which are respectively arranged opposite to the two exhaust holes 111 to prevent the valve plate body 41 from affecting the compressor exhaust. The exhaust through holes 44 communicate with the valve gap 421, which can reduce the clearance in the compressor exhaust process, thereby effectively increasing the exhaust volume. At the same time, it facilitates the one-time processing of the holes and gaps on the intake valve plate 4.

[0078] The intake valve plate 4 also includes a fixing part 43. The valve tongue 42 is provided with a second mounting hole 47. The fixing part 43 is disposed in the second mounting hole 47, and one end of the fixing part 43 in the length direction is connected to the hole wall of the second mounting hole 47. There is a gap between the fixing part 43 and the hole wall of the first mounting hole 46, which makes the connection area between the valve tongue 42 and the valve plate body 41 smaller, thus reducing the resistance when the valve tongue 42 moves and increasing the efficiency of the valve tongue 42 in opening or closing the intake port 12. In the projection of the valve plate 1 in the thickness direction, the fixing part 43 is spaced apart from the intake port 12 to avoid the fixing part 43 affecting the compressor exhaust.

[0079] The compressor according to an embodiment of the present invention includes the valve assembly 100 described above.

[0080] According to an embodiment of the present invention, the compressor can effectively accelerate the exhaust speed and improve the exhaust efficiency by providing two exhaust holes 111 on the valve plate 1. The exhaust valve plate 2 includes an assembly part 21 and two exhaust parts 22. The two exhaust parts 22 are respectively arranged opposite to the two exhaust holes 111, which reduces the impact speed of the exhaust valve plate 2, avoids the exhaust parts 22 continuously hitting the valve plate 1 at high frequency, avoids damage to the exhaust valve plate 2, and improves the service life of the compressor. At the same time, the assembly part 21 is located between the two exhaust holes 111 and is fixedly connected to the valve plate 1. The two exhaust parts 22 are located at both ends of the assembly part 21 along the first direction and are connected to the assembly part 21. The two exhaust parts 22 are respectively arranged opposite to the two exhaust holes 111 and are used to open or close the exhaust holes 111, making the assembly process of the exhaust valve plate 2 and the valve plate 1 simple and convenient.

[0081] The refrigeration equipment according to an embodiment of the present invention includes the compressor described above.

[0082] According to the refrigeration equipment of the present invention, by providing two exhaust holes 111 on the valve plate 1, the exhaust speed can be effectively accelerated and the exhaust efficiency improved. The exhaust valve plate 2 includes an assembly part 21 and two exhaust parts 22. The two exhaust parts 22 are respectively arranged opposite to the two exhaust holes 111, which reduces the impact speed of the exhaust valve plate 2, avoids the exhaust parts 22 continuously hitting the valve plate 1 at high frequency, avoids damage to the exhaust valve plate 2, and improves the service life of the compressor. At the same time, the assembly part 21 is located between the two exhaust holes 111 and is fixedly connected to the valve plate 1. The two exhaust parts 22 are located at both ends of the assembly part 21 along the first direction and are connected to the assembly part 21. The two exhaust parts 22 are respectively arranged opposite to the two exhaust holes 111 and are used to open or close the exhaust holes 111, making the assembly process of the exhaust valve plate 2 and the valve plate 1 simpler and more convenient.
