Abstract
Description
Technical Field
[0001] This invention relates to the field of valve plate technology, and more particularly to a novel exhaust structure intake valve plate. Background Technology
[0002] With increasingly stringent requirements for energy conservation and emission reduction, compressors, as the core component and energy-intensive part of refrigeration systems, face higher demands on their refrigeration performance and energy efficiency. The suction valve, as a one-way valve controlling the compressor's refrigerant intake, is a critical component of the refrigerator compressor, directly affecting its refrigerant intake capacity and overall cooling output. Currently, the springs of most suction valves are vertically or horizontally positioned, and the unreasonable design of the gap and angle between the spring and the valve body leads to turbulence generated by the vertical impact when the refrigerant enters, increasing flow resistance. This results in a typically large spring opening, leading to greater striking force and noise, slower response time, and a shortened lifespan for the suction valve. Summary of the Invention

[0021] In this embodiment, a novel exhaust structure intake valve plate is characterized by comprising a valve plate body 100, a spring 200 disposed on the valve plate body 100, and an irregularly shaped opening 300 disposed on the valve plate body 100; wherein The reed 200 has a gap 230 between it and the valve body 100 and is inclined relative to the first direction side of the valve body 100. The irregular-shaped opening 300 is located on one side of the center position of the valve plate body 100.
[0022] In this embodiment, a gap 230 is reserved between the reed 200 and the valve body 100, and the reed is tilted to the side along the first direction. Compared with the traditional vertical or horizontal reed 200, this reduces the airflow impact resistance during suction. The tilted reed 200 guides the refrigerant airflow to enter the inner side of the valve more smoothly, avoiding eddy current losses caused by the airflow hitting the reed 200 vertically, thereby improving the suction response speed. The deformation path of the tilted reed 200 when opening or closing is more in line with the airflow direction, thus effectively reducing valve vibration noise. Moreover, the irregularly shaped opening 300 prevents refrigerant from accumulating in the central area, ensuring that the refrigerant contacts the surrounding structure of the valve body 100 more evenly, reducing the amount of refrigerant residue that does not participate in heat exchange, directly improving refrigerant utilization efficiency, and indirectly reducing compressor energy consumption.
[0023] The valve body 100 is rectangular in shape, and arc-shaped structures 110 for limiting the position are provided at the four corners of the valve body 100. In some embodiments, the arc-shaped structures 110 disperse the force at the four corners of the valve body 100, transforming localized concentrated stress into uniform arc-shaped surface force, thereby extending the service life of the valve body, which is especially suitable for compressors with high-frequency start-stop.
[0024] In some embodiments, the two sets of arc-shaped structures 110 are provided with arc-shaped positioning notches 120 for positioning, and the two arc-shaped positioning notches 120 are located on the same side along the longitudinal direction of the valve body 100. In some embodiments, setting the arc-shaped positioning notches 120 on the same side of the longitudinal direction of the valve body 100 can avoid the problem of reverse installation during valve assembly, and setting the arc-shaped positioning notches 120 can further improve the assembly accuracy.
[0025] In some embodiments, mounting holes 130 concentric with the corresponding arc-shaped structures 110 are respectively opened on the inner side of the four corners of the valve body 100. Two sets of auxiliary holes 140 are also opened on the valve body 100, symmetrically positioned between the two mounting holes 130 located in the longitudinal direction of the valve body 100. In some embodiments, by setting the mounting holes 130 concentric with the arc-shaped structures 110, it can be ensured that the force direction of the fastener used when tightening the intake valve is consistent with the stress distribution direction of the arc-shaped structure 110, avoiding uneven local stress on the valve body due to misalignment of the mounting holes 130, and improving fixing stability. In some embodiments, the two sets of auxiliary holes 140 are positioned relative to the nearest mounting hole 130, and can be adjusted according to the shape of the valve body 100 and the irregular opening 300, thereby adjusting the center of gravity of the valve body 100 and effectively reducing vibration noise.
[0026] In some embodiments, the reed 200 includes a cantilever 210 connected to the valve body 100, and a tail 220 connected to the other end of the cantilever 210. The tail 220 is arc-shaped and transitions to the cantilever 210 in an arc shape. In this embodiment, the cantilever 210 is responsible for connecting the valve body 100 and providing elastic deformation force. The arc-shaped tail 220 of the reed 200 can increase the contact area with the airflow, which can improve the airflow propulsion efficiency during inhalation. At the same time, it makes the deformation of the tail 220 smooth. Moreover, the arc transition between the cantilever 210 and the tail 220 avoids stress concentration at the connection between the cantilever 210 and the tail 220, ensuring that the reed 200 can maintain stable elastic performance when opening or closing at high frequency, and reducing the problem of untimely inhalation caused by the reed 200 jamming.
[0027] In some embodiments, the angle between the centerline of the reed 200 and the radial side of the valve body 100 is α, and the angle α ranges from 10 to 55°. In some embodiments, the angle α ranges from 15°. In some embodiments, the angle α ranges from 20°. In some embodiments, the angle α ranges from 25°. In some embodiments, the angle α ranges from 30°. In some embodiments, the angle α ranges from 35°. In some embodiments, the angle α ranges from 45°. In some embodiments, a suitable range of α can be selected according to the type of refrigerant used to select cantilever 210 of different lengths to adapt to the application.
[0028] In some embodiments, the irregularly shaped opening 300 includes a first side 310 arranged in the radial direction and a second side 320 and a third side 330 arranged in the longitudinal direction and located on both sides of the first side 310. The first side 310 and the second side 320 are rounded, the first side 310 and the third side 330 are rounded, and the second side 320 and the third side 330 are connected by a rounded edge 340 protruding away from the first side 310. In this embodiment, the rounded transitions between the first side 310 and the second side 320, and between the first side 310 and the third side 330, avoid airflow vortices at traditional right-angle openings, allowing the refrigerant to flow along the smooth rounded surfaces, reducing resistance. Moreover, the flared structure formed by the outwardly protruding rounded edge 340 can expand the airflow channel area at the outlet end of the irregularly shaped opening 300, further reducing the local resistance when the refrigerant flows out of the irregularly shaped opening 300, while guiding the airflow to diffuse more evenly to the inside of the valve plate, avoiding local airflow accumulation, and maximizing the contact efficiency between the refrigerant and the heat exchange components.
[0029] In some embodiments, the second side 320 and the third side 330 are symmetrical about the centerline of the first side 310. In this embodiment, the symmetrical arrangement of the second side 320 and the third side 330 enables the airflow to diffuse evenly to both sides along the centerline of the first side 310, ensuring the force balance of the reed 200, while avoiding increased valve vibration noise caused by airflow imbalance, further improving the overall operational stability.
