Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of compressors, and in particular relates to an energy-saving integrated electric vortex compressor. Background Art
[0002] The scroll compressor, also known as the vortex compressor, has an exquisite core structure, which is a combination of a fixed involute scroll and an eccentric gyratory translational involute scroll, which together build a highly efficient compression volume. These two components are carefully carved according to the double function equation line, and they are tightly meshed with each other, like precision gears, and cooperate tacitly in the cycle of intake, compression and exhaust.
[0003] In terms of operating mechanism, the stationary scroll is firmly anchored on the frame like a solid foundation; while the movable scroll is driven by a precise eccentric shaft and cleverly constrained by an anti-rotation mechanism to ensure that it rotates in a plane with an extremely small radius around the center of the stationary disk base circle. This process is both precise and efficient.
[0004] However, in the face of the growing demand for energy efficiency and stability, the performance of traditional static and dynamic scrolls in the operation process seems to be slightly insufficient. They have encountered bottlenecks in the pursuit of higher levels of smooth compression and energy efficiency improvement, resulting in unsatisfactory energy-saving effects. At the same time, in long-term operation, they also face the challenges of leakage risks and increased energy loss. These problems not only affect the overall performance of the compressor, but also limit its application and development in a wider range of fields.
[0005] Therefore, it is very necessary to invent an energy-saving integrated electric eddy current compressor. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides an energy-saving integrated electric vortex compressor, including a vortex static and dynamic disk mechanism, a cover, a housing, a driving component, a crank shaft and a bottom cover, wherein the vortex static and dynamic disk mechanism is installed in the cover and the housing, and the cover and the housing are sealed and fixedly installed together, the driving component is installed in the housing, and the driving component is connected to the vortex static and dynamic disk mechanism through the crank shaft; the bottom cover is fixedly installed on the vortex static and dynamic disk mechanism;
[0007] The scroll movable disc mechanism includes a chassis seat, a scroll movable disc, a scroll stator, a channel arc convexity and a throttling recess, the chassis seat is fixedly connected to the crank shaft; the scroll movable disc is fixedly mounted on the chassis seat, the scroll movable disc and the scroll stator are mounted together, and the scroll stator is fixedly mounted on the cover; the channel arc convexity and the throttling recess are installed on the scroll movable disc and the scroll stator.
[0008] Preferably, the scroll movable plate and the scroll stator plate are scroll-shaped structures, with a compression chamber for compressing the medium therebetween; and the cover is provided with a pipe opening for the medium to enter and a pipe opening for the medium to discharge.
[0009] Preferably, the channel arc protrusion is an arc-shaped protrusion, and the outer surfaces of the scroll movable plate and the scroll stator plate are both provided with channel arc protrusions, and the channel arc protrusions on the scroll movable plate and the scroll stator plate are in contact with each other.
[0010] Preferably, the throttling recess is provided on the surface of the middle area between the vortex movable plate and the vortex stator plate, and the throttling recess is an elliptical recessed area. The throttling recess is provided below the pipe outlet for discharging the medium of the cover, and the channel arc convex is not provided around the throttling recess area where the vortex movable plate and the vortex stator plate are provided.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The design of the throttling recess of the utility model enables a certain throttling effect to be generated when the medium flows through these recessed areas during the compression process. This throttling effect helps to control the flow rate and pressure changes of the medium, making the compression process more stable and efficient. Compared with the design without throttling recess, it reduces the energy loss caused by excessive flow rate of the medium or sudden pressure change, thereby improving the overall efficiency of the compressor.
[0013] In addition, the arc convex of the channel is the contact part between the scroll moving plate and the scroll stator. Its arc design can better fit the gap between the two plates and form an effective seal. This design reduces the possibility of medium leakage from the gap during the compression process and ensures the sealing of the compression chamber. At the same time, the arc convex can also play a guiding role during the compression process, making the relative movement between the scroll moving plate and the scroll stator more stable, further reducing leakage and energy loss.

[0021] As attached Figure 1 To Attachment Figure 3 As shown:
[0022] The utility model provides an energy-saving integrated electric vortex compressor, comprising a vortex static and dynamic disk mechanism 1, a cover 2, a shell 3, a driving component 4, a crank shaft 5 and a bottom cover 6, wherein the vortex static and dynamic disk mechanism 1 is installed in the cover 2 and the shell 3, the cover 2 and the shell 3 are sealed and fixed together, the driving component 4 is installed in the shell 3, and the driving component 4 is connected to the vortex static and dynamic disk mechanism 1 through the crank shaft 5; the bottom cover 6 is fixedly installed on the vortex static and dynamic disk mechanism 1.
[0023] The scroll plate mechanism 1 includes a chassis seat 11, a scroll plate 12, a scroll plate 13, a channel arc convex 14 and a throttling recess 15. The chassis seat 11 is fixedly connected to the crankshaft 5; the scroll plate 12 is fixedly mounted on the chassis seat 11, the scroll plate 12 and the scroll plate 13 are mounted together, and the scroll plate 13 is fixedly mounted on the cover 2; the channel arc convex 14 and the throttling recess 15 are installed on the scroll plate 12 and the scroll plate 13. The scroll plate mechanism 1 improves compression efficiency, enhances sealing performance, reduces noise and vibration, optimizes airflow path, and prolongs service life.
[0024] Embodiment 1:
[0025] Specifically, both the scroll plate 12 and the scroll plate 13 adopt a scroll-type structure design, which mesh with each other and jointly construct one or more chambers for compressing the medium. This design not only ensures the continuity and efficiency of the compression process, but also achieves effective guidance and compression of the medium through the unique advantages of the scroll structure.
[0026] Specifically, a pipe opening for medium entry and a pipe opening for medium discharge are cleverly arranged on the cover 2. The two pipe openings are respectively located on one side and above the compression chamber formed by the scroll moving plate 12 and the scroll stator 13, ensuring that the medium can smoothly enter and be discharged after being compressed, providing the necessary fluid channel for the entire compression process.
[0027] Specifically, in order to further enhance the sealing and movement stability between the scroll moving plate 12 and the scroll stator 13, the outer surfaces of both are provided with channel arc protrusions 14. These arc-shaped protrusions contact each other to form a tight fitting surface, which effectively reduces the leakage of the medium during the compression process. At the same time, the channel arc protrusions 14 also play a guiding role, guiding the scroll moving plate 12 to rotate smoothly around the center of the stator base circle under the drive of the eccentric shaft, ensuring the continuity and stability of the compression process.
[0028] Specifically, a throttling depression 15 is specially provided on the surface of the middle area between the vortex moving plate 12 and the vortex stator 13. These elliptical depression areas are located below the medium discharge pipe opening of the cover 2, and the flow rate and pressure changes of the medium are controlled by generating a throttling effect. During the compression process, when the medium flows through the throttling depression 15, its flow rate will slow down and the pressure will increase accordingly, thereby achieving fine control of the compression process. This design not only improves the overall efficiency of the compressor, but also reduces the energy loss caused by excessive medium flow rate or sudden pressure change.
[0029] Specifically, the channel arc convex 14 is not provided around the throttling recess 15 area provided on the scroll moving plate 12 and the scroll stator plate 13. This design decision is intended to avoid interference of the channel arc convex 14 with the function of the throttling recess 15, ensuring that the throttling effect can be fully exerted. At the same time, this also provides convenient conditions for the maintenance and repair of the throttling recess 15.
[0030] Embodiment 2:
[0031] Vortex structure compression: Both the vortex moving plate 12 and the vortex stator 13 are designed with a vortex structure, which mesh with each other to form a number of crescent-shaped compression chambers. As the vortex moving plate 12 rotates around the base circle center of the vortex stator 13 driven by the eccentric shaft, the volume of these compression chambers gradually decreases, thereby compressing the inhaled medium.
[0032] Medium flow control: During the compression process, the medium enters the compressor through the medium inlet port on the cover 2 and is gradually compressed as the scroll plate 12 rotates. When the medium flows through the throttling recess 15 in the middle area of the scroll plate 12 and the scroll plate 13, a throttling effect is generated, thereby controlling the flow rate and pressure change of the medium, making the compression process more stable and efficient.
[0033] Sealing and guiding: The channel arc convex 14 is the contact part between the scroll moving plate 12 and the scroll stator 13. Its arc design ensures the close fit between the two, effectively reducing the leakage of the medium during the compression process. At the same time, the channel arc convex 14 also plays a guiding role, making the rotation of the scroll moving plate 12 more stable.
[0034] Energy conversion and output: The driving component 4 converts electrical energy into mechanical energy through the crankshaft 5, driving the scroll plate 12 to rotate. The compressed medium is discharged through the medium discharge port on the cover 2, completing the entire compression process.
[0035] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
