Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a compressor variable cylinder structure, and also to a compressor having the compressor variable cylinder structure. Background Art

[0002] Most of the existing compressors have fixed cylinders, and the amount of refrigerant sucked in and compressed each time is also fixed. Although there is a way to add more refrigerant to the cylinder by adding air to increase enthalpy, this method is relatively traditional and requires additional equipment. Especially when manufacturing the new refrigerant R290, due to the limitation of the volume in the cylinder, the amount of refrigerant sucked in and compressed each time is fixed, which cannot improve the performance of the compressor, is inefficient, and is not conducive to the production of refrigerants. Summary of the invention

[0003] The purpose of the present invention is to overcome the problems of the prior art and provide a compressor variable cylinder structure that can increase the amount of refrigerant sucked in and compressed, improve work efficiency, and facilitate refrigerant production. A compressor having the compressor variable cylinder structure is also provided.

[0004] In order to achieve the above object, the present invention adopts the following scheme:

[0005] A compressor cylinder variable structure comprises a cylinder body and a crankshaft passing through the cylinder body and being rotatable, wherein the cylinder body comprises a cavity, and the cylinder body also has a sliding cavity communicating with the cavity; the compressor cylinder variable structure further comprises:

[0006] A first eccentric wheel, which is disposed in the cavity and connected to the crankshaft;

[0007] A variable cylinder slider is disposed in the sliding chamber and connected to the first eccentric wheel; the crankshaft drives the first eccentric wheel to rotate synchronously to drive the variable cylinder slider to reciprocate in the sliding chamber;

[0008] A roller mechanism is arranged in the cavity and connected to the crankshaft; the crankshaft drives the roller mechanism to rotate synchronously to compress the refrigerant.

[0009] Furthermore, the variable cylinder slider is cooperatively embedded in the sliding cavity and can reciprocate along the elongation direction of the sliding cavity.

[0010] Furthermore, the roller mechanism comprises:

[0011] A second eccentric wheel is sleeved on the crankshaft and rotates synchronously with the crankshaft;

[0012] The roller is arranged on the second eccentric wheel and rotates eccentrically with the second eccentric wheel in synchronization with the second eccentric wheel to compress the refrigerant.

[0013] Furthermore, the rotation eccentric angle of the first eccentric wheel and the second eccentric wheel is 180 0 .

[0014] Furthermore, the first eccentric wheel is slidably connected to the variable cylinder slider via a slider connecting arm to drive the variable cylinder slider to reciprocate in the sliding chamber.

[0015] Furthermore, the roller mechanism is located above the first eccentric wheel.

[0016] Furthermore, a partition plate located above the first eccentric wheel is provided at the lower end of the cylinder body.

[0017] Furthermore, it also includes an upper flange arranged at the upper end of the cylinder body, a lower flange arranged at the lower end of the cylinder body and located below the first eccentric wheel, a sliding plate arranged on the cylinder body, and an air intake hole and an air exhaust hole respectively connected to the cavity.

[0018] The present invention also discloses a compressor, which includes the compressor variable cylinder structure described above.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The compressor variable cylinder structure of the present invention adds a sliding cavity connected to the cavity, and uses the crankshaft to drive the first eccentric wheel to rotate synchronously to drive the variable cylinder slider to reciprocate in the sliding cavity.

DETAILED DESCRIPTION

[0029] The present invention is further described in conjunction with the following examples.

[0030] See also Figures 1 to 5 A compressor variable cylinder structure includes a cylinder body 1 and a crankshaft 2 that passes through the cylinder body 1 and is rotatable. The cylinder body 1 includes a cavity 11, and the cylinder body 1 also has a sliding cavity 12 that is connected to the cavity 11; the compressor variable cylinder structure also includes a first eccentric wheel 3, a variable cylinder slider 4 and a roller mechanism 5. Among them, the first eccentric wheel 3 is arranged in the cavity 11 and connected to the crankshaft 2; the variable cylinder slider 4 is arranged in the sliding cavity 12 and connected to the first eccentric wheel 3; the crankshaft 2 drives the first eccentric wheel 3 to rotate synchronously to drive the variable cylinder slider 4 to reciprocate in the sliding cavity 12; the roller mechanism 5 is arranged in the cavity 11 and connected to the crankshaft 2; the crankshaft 2 drives the roller mechanism 5 to rotate synchronously for compressing refrigerant. The variable cylinder structure of the compressor is achieved by adding a sliding chamber 12 in the chamber 11 which is connected to the chamber 11, and utilizing the crankshaft 2 to drive the first eccentric wheel 3 to rotate synchronously to drive the variable cylinder slider 4 to reciprocate in the sliding chamber 12. The variable cylinder slider 12 regularly moves so that the sum of the volumes between the chamber 11 and the sliding chamber 12 changes, which helps to inhale more gas into the cylinder body 1, and cooperates with the movement of the rotating roller mechanism 5 to achieve more refrigerant compression, thereby improving the overall performance of the variable cylinder structure of the compressor, improving work efficiency, and increasing the amount of refrigerant inhaled and compressed by the compressor each time, which is beneficial to the production of refrigerant.

[0031] In this specific embodiment, the variable cylinder slider 4 is matched and embedded in the sliding cavity 12 and can reciprocate along the extension direction of the sliding cavity 12. By matching and embedding the variable cylinder slider 4 in the sliding cavity 12, a good seal is formed, which helps the roller mechanism to compress a large amount of refrigerant in the cylinder body 1 each time.

[0032] Preferably, the first eccentric wheel 3 is slidably connected with the variable cylinder slider 4 through a slider connecting arm 6 to drive the variable cylinder slider 4 to reciprocate in the sliding chamber 12. The first eccentric wheel 3 is driven to rotate synchronously by the crankshaft 2, so that the first eccentric wheel 3 eccentrically pushes the slider connecting arm 6 during the rotation process, thereby driving the variable cylinder slider 4 to reciprocate in the sliding chamber 12, so that the sum of the volumes between the cavity 11 and the sliding chamber 12 changes, which helps to inhale more gas into the cylinder body 1, cooperates with the movement of the rotating roller mechanism 5, realizes more refrigerant compression, improves the overall performance of the compressor variable cylinder structure, improves the working efficiency, increases the amount of refrigerant inhaled and compressed by the compressor each time, and is beneficial to the production of refrigerant.

[0033] The roller mechanism 5 includes a second eccentric wheel 51 and a roller 52. The second eccentric wheel 51 is sleeved on the crankshaft 2 and rotates synchronously with the crankshaft 2; the roller 52 is arranged on the second eccentric wheel 51 and rotates synchronously with the second eccentric wheel 51 to compress the refrigerant. Specifically, the rotation eccentric angle of the first eccentric wheel 3 and the second eccentric wheel 51 is 180 0 By setting the compressor variable cylinder structure in this way to change the internal volume structure of the cylinder body 1, when the compressor inhales air, the variable cylinder slider 4 gradually slides away from the cavity 11, and the sum of the volumes between the cavity 11 and the sliding cavity 12 gradually increases, and the amount of refrigerant inhaled gradually increases. Figure 1 When the slider 4 slides away from the farthest position of the cavity 11, the sum of the volumes between the cavity 11 and the sliding cavity 12 is the largest, and the gas inhaled into the cylinder is the largest, and the suction begins and ends at the same time. Figure 2 When the cylinder slide block 4 moves from the position, the suction has ended, the roller 52 starts to compress the sucked gas, and the cylinder slide block 4 gradually slides close to the cavity 11. Figure 2 Position movement to Figure 3 When the roller 52 is in the position, the gas sucked in is in a state of complete compression, the sum of the volumes between the cavity 11 and the sliding cavity 12 is the smallest, and the cylinder slider 4 slides close to the closest position of the cavity 11. At the same time, the cylinder slider 4 gradually begins to move away from the cavity 11. Figure 3 Position movement to Figure 4 position, the variable cylinder slider 4 continues to move away from the cavity 11, and the compressor continues to inhale air, forming a cycle in this way, so that the sum of the volumes between the cavity 11 and the sliding cavity 12 changes, which helps to inhale more gas into the cylinder 1, and cooperates with the movement of the rotating roller mechanism 5 to achieve more refrigerant compression, thereby improving the overall performance of the compressor variable cylinder structure, improving work efficiency, and increasing the amount of refrigerant inhaled and compressed by the compressor each time, which is beneficial to the production of refrigerant.

[0034] The roller mechanism 5 is located above the first eccentric wheel 3 .

[0035] The lower end of the cylinder body 1 is provided with a partition plate 7 located above the first eccentric wheel 3. The partition plate separates the first eccentric wheel 3 and the cavity 11 to prevent the first eccentric wheel 3 from affecting the compressor to absorb and compress the refrigerant.

[0036] The compressor variable cylinder structure also includes an upper flange 8 arranged at the upper end of the cylinder body 1, a lower flange 9 arranged at the lower end of the cylinder body 1 and located below the first eccentric wheel 3, a slide 10 arranged on the cylinder body 1, and an intake hole 13 and an exhaust hole 14 respectively connected to the cavity 11.

[0037] The present invention also discloses a compressor, which includes the compressor variable cylinder structure described above.

[0038] The variable cylinder structure of the compressor is achieved by adding a sliding chamber 12 in the chamber 11 which is connected to the chamber 11, and utilizing the crankshaft 2 to drive the first eccentric wheel 3 to rotate synchronously to drive the variable cylinder slider 4 to reciprocate in the sliding chamber 12. The variable cylinder slider 12 regularly moves so that the sum of the volumes between the chamber 11 and the sliding chamber 12 changes, which helps to inhale more gas into the cylinder body 1, and cooperates with the movement of the rotating roller mechanism 5 to achieve more refrigerant compression, thereby improving the overall performance of the variable cylinder structure of the compressor, improving work efficiency, and increasing the amount of refrigerant inhaled and compressed by the compressor each time, which is beneficial to the production of refrigerant.

[0039] In summary, the implementation methods of the present application have been described in detail, but the present application is not limited to the above implementation methods. Even if various changes are made to the present application, they still fall within the protection scope of the present application.
