Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a compressor and an air conditioning system. Background Technology

[0002] The compressor is equipped with an oil baffle plate, which is used to prevent lubricating oil from splashing or overflowing. It also intercepts the lubricating oil carried by the refrigerant when it is discharged from the compressor, preventing the lubricating oil from entering the condenser, evaporator and other equipment in the refrigeration cycle system. In addition, the intercepted oil droplets accumulate on the surface of the oil baffle plate and flow back to the oil sump of the compressor along a specific path, so as to avoid the compressor running out of oil and thus reducing its working efficiency.

[0003] In existing technologies, the oil baffle is installed to the end of the rotor using a riveting process. However, the riveting process is complex and prone to problems such as poor riveting or rivet falling off, which can lead to the oil baffle not being installed properly or falling off, thereby reducing the reliability of the compressor. Utility Model Content

[0034] To address the problems in the prior art, this utility model provides a compressor. Figure 1 A side view of an oil baffle of a compressor according to an embodiment of the present invention is shown; Figure 2 A top view of an oil baffle of a compressor according to an embodiment of the present invention is shown; Figure 3 This diagram shows a compressor oil baffle and crankshaft assembled together according to an embodiment of the present invention.

[0035] like Figures 1 to 3 As shown, the compressor includes a crankshaft and an oil baffle 20. The crankshaft is internally continuous; the crankshaft includes a long shaft portion 11 and a short shaft portion (not shown in the figure) arranged opposite each other, and a first limiting structure 111 is provided on the inner wall of the long shaft portion 11.

[0036] The oil baffle 20 has an internal cavity that communicates with the inside of the crankshaft. The oil baffle 20 includes a mounting part 21 and an oil-blocking part 22. The mounting part 21 has a central through hole 211, and the oil-blocking part 22 is arranged circumferentially around the central through hole 211. The mounting part 21 has a second limiting structure 212. The second limiting structure 212 is located inside the long shaft part 11, and the oil baffle 20 is connected to the long shaft part 11 through the first limiting structure 111 and the second limiting structure 212. The oil-blocking part 22 extends beyond the long shaft part 11 and is away from the short shaft part.

[0037] In this technical solution, a first limiting structure 111 is provided on the inner wall of the long shaft portion 11 of the crankshaft, and a second limiting structure is provided on the outer wall of the mounting portion 21 of the oil baffle 20. When the first limiting structure is set inside the long shaft portion 11, the oil baffle 20 can be fixedly connected to the crankshaft through the first limiting structure and the second limiting structure. The oil baffle 20 configured in this way is easy to install, firmly installed and not easy to fall off, thereby improving the working reliability of the compressor.

[0038] Furthermore, such as Figure 3As shown, the first limiting structure 111 is a mounting groove, the second limiting structure 212 is a claw, and the mounting part 21 includes a hollow cylinder with the claw disposed on the outer wall of the cylinder. The claw is embedded in the mounting groove to fix the oil baffle 20 to the long shaft part 11.

[0039] Furthermore, in some embodiments, the mounting groove is a continuous annular groove. That is, the inner wall of the long shaft portion 11 is provided with a continuous groove in the circumferential direction.

[0040] Furthermore, in some other embodiments, the mounting grooves include a plurality of spaced-apart grooves arranged circumferentially along the inner wall of the long shaft portion 11. That is, the plurality of mounting grooves are not continuous, but spaced apart on the inner wall of the long shaft portion 11. This arrangement of mounting grooves can prevent the oil baffle 20 from rotating relative to the crankshaft when it rotates together with the crankshaft.

[0041] Please continue reading. Figure 3 The interior of the long shaft portion 11 is provided with a connecting receiving hole 112 and a flow passage hole 113. The receiving hole 112 is used to receive the mounting portion 21, and the diameter of the receiving hole 112 is greater than or equal to the diameter of the flow passage hole 113. Figure 3 The diameter of the receiving hole 112 is larger than the diameter of the flow hole 113, and a stepped surface is formed between the receiving hole 112 and the flow hole 113. When the oil baffle 20 is installed into the receiving hole 112, part of the structure of the pawl is embedded in the mounting groove, and part of the structure abuts against the stepped surface. The stepped surface can prevent the oil baffle 20 and the crankshaft from moving downward in the axial direction, so that the oil baffle 20 and the crankshaft are firmly connected.

[0042] Furthermore, the claws are arranged circumferentially along the cylindrical body. This arrangement ensures that the forces on the parts where the claws connect with the mounting grooves are evenly distributed, preventing the oil baffle 20 from failing due to uneven force distribution.

[0043] Furthermore, such as Figure 1 and Figure 3 As shown, the oil baffle 22 includes a base plate 221 and a side wall 222. The first end of the side wall 222 is connected to the mounting part 21, and the second end of the side wall 222 is connected to the base plate 221. The oil baffle 22 is used to prevent lubricating oil flowing upward from the crankshaft's flow hole 113 and receiving hole 112 from splashing and overflowing.

[0044] Furthermore, such as Figure 1 and Figure 3 As shown, the oil baffle 220 is provided with an oil passage hole 223 that penetrates the side wall 222. The lubricating oil collected on the oil baffle 22 can flow out of the interior of the oil baffle 20 through the oil passage hole 223 and then flow back into the oil sump of the compressor, reducing the oil output rate of the compressor.

[0045] Furthermore, such as Figure 1 and Figure 3 As shown, the base plate 221 is recessed towards the inside of the crankshaft to form an arc surface, and a guide cavity is formed between the arc surface and the side wall 222. The base plate 221 is set as an arc surface (curved surface), which can guide the lubricating oil impacting the guide cavity, reduce the impact force of the lubricating oil on the base plate 221 of the oil baffle 20, and improve the reliability of the oil baffle 20.

[0046] This utility model also provides an air conditioning system, including the compressor described above. Since the air conditioning system includes the compressor described above, it achieves all the technical effects of the compressor described above, which will not be repeated here.

[0047] In summary, the compressor and air conditioning system provided by this utility model have the following advantages:

[0048] By setting a first limiting structure on the inner wall of the long shaft portion of the crankshaft and a second limiting structure on the mounting portion of the oil baffle, when the first limiting structure is set inside the long shaft portion, the oil baffle can be fixedly connected to the crankshaft through the first and second limiting structures. The oil baffle configured in this way is easy to install, firmly installed and not easy to fall off, thereby improving the working reliability of the compressor.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
