Abstract

The present disclosure provides a compressor and an air conditioner having the same. The compressor includes: a main shaft with a convex portion and a slip sheet; a cylinder; and an air inlet and outlet device including a disk body and an air suction port including an outer side, an inner side and a connecting side located between the outer side and the inner side, wherein the outer side is overlapped with an inner wall of the cylinder or is located on the inner side of the inner wall of the cylinder, the inner side is overlapped with an outer wall of the convex portion or is located on the outer side of the convex portion, and the connecting side is overlapped with a side wall of the slip sheet or is located on the inner side of the side wall of the slip sheet.

Claims

1. A compressor, comprising:

a main shaft provided with a convex portion, and a slip sheet installed on the convex portion;

a cylinder wherein the convex portion and the slip sheet are penetrated in an inner cavity of the cylinder; and

an air inlet and outlet device sleeved on the main shaft and located at least one position above or below the cylinder, and the air inlet and outlet device comprises a disk body, an air suction port communicating with the inner cavity is formed on an end of the disk body facing to the cylinder, the air suction port comprises an outer side, an inner side and a connecting side located between the outer side and the inner side;

wherein the outer side is overlapped with an inner wall of the cylinder or is located on an inner side of the inner wall of the cylinder, the inner side is overlapped with an outer wall of the convex portion or is located on an outer side of the convex portion, and when the basic-volume of the cylinder is the maximum, the connecting side is overlapped with a side wall of the slip sheet closest to the air suction port and facing to a rotating direction of the main shaft or is located on an inner side of the side wall of the slip sheet.

2. The compressor according to claim 1, wherein the compressor further comprises an upper flange and a lower flange, the cylinder is located between the upper flange and the lower flange, and at least one of the upper flange and the lower flange forms the air inlet and outlet device.

3. The compressor according to claim 1, wherein the compressor further comprises an upper flange, a lower flange and a partition plate located between the upper flange and the lower flange, the cylinder is located between the upper flange and the lower flange, the partition plate forms the air inlet and outlet device.

4. The compressor according to claim 3, wherein the partition plate is located between the upper flange and the cylinder or between the lower flange and the cylinder, an overflow channel communicating the air suction port with the outside is arranged on the upper flange or the lower flange, the overflow channel comprises an overflow port formed on an end of the upper flange or the lower flange facing to the partition plate, and the air suction port is located within the range of the overflow port.

5. The compressor according to claim 3, wherein a plurality of cylinders are provided, and the partition plate is arranged between two adjacent cylinders.

6. The compressor according to claim 1, wherein a radial air suction port communicating with the air suction port is further formed in the disk body.

7. The compressor according to claim 1, wherein the connecting side is connected between a first end of the outer side and a first end of the inner side, and the air suction port further comprises a transition side connected between a second end of the outer side and a second end of the inner side.

8. The compressor according to claim 1, wherein the cylinder comprises a bearing outer ring and a bearing inner ring arranged in the bearing outer ring, the outer side is overlapped with the inner wall of the bearing inner ring or is located on the inner side of the inner wall of the bearing inner ring.

9. The compressor according to claim 8, wherein the cylinder further comprises a holder and a rolling body which are arranged between the bearing outer ring and the bearing inner ring.

10. The compressor according to claim 1, wherein an exhaust port communicating with the inner cavity is formed on the end of the disk body facing to the cylinder, and the exhaust port is configured to be completely covered by the slip sheet.

11. The compressor according to claim 10, wherein the width L1 of the exhaust port and the thickness L2 of the slip sheet satisfies the following relationship:

L1≤
