压缩机

Abstract

本实用新型属于涡旋压缩机技术领域，公开了压缩机，该压缩机包括外壳和导管组件，外壳内设有静涡旋，静涡旋具有喷气增焓孔，导管组件具有进气端和出气端，导管组件的出气端与喷气增焓孔连通，导管组件密封固定于外壳且导管组件的进气端位于外壳外，与传统的连接管和喷气管分体式结构相比，导管组件通过铸造等方式一体成型，导管组件安装至静涡旋并与喷气增焓管连通后固定在外壳上，避免了独立的连接管接管位置不正而造成的喷气管安装困难的问题，大大降低对喷气管的制造要求和成本。

Claims

The air outlet (22) of the conduit assembly (2) is connected to the jet enthalpy enhancement hole. The conduit assembly (2) is sealed and fixed to the housing (1), and the air inlet (21) of the conduit assembly (2) is located outside the housing (1).

2. The compressor of claim 1, wherein, The compressor also includes a one-way valve assembly (3), which is disposed inside the conduit assembly (2). A moving vortex is also provided inside the housing (1). The moving vortex meshes with the stationary vortex (11) to form a compression chamber that communicates with the jet enthalpy-increasing orifice. The one-way valve assembly (3) is used to allow the enthalpy-increasing medium to flow unidirectionally from the conduit assembly (2) to the compression chamber. The one-way valve assembly (3) includes a valve core (31). Along the axial direction of the conduit assembly (2), the valve core (31) is movably disposed inside the conduit assembly (2) and is used to open or close the air inlet end (21) of the conduit assembly (2).

3. The compressor of claim 1, wherein, The static vortex (11) is fixedly installed on the outer shell (1).

4. The compressor of claim 2, wherein, The one-way valve assembly (3) further includes a limiting member (32), which is disposed within the conduit assembly (2). The limiting member (32) has a vent hole (321), and the valve core (31) can abut against the limiting member (32) to block the vent hole (321).

5. The compressor of claim 4, wherein, The one-way valve assembly (3) further includes an elastic retaining ring (33), which is disposed inside the conduit assembly (2). The inner wall of the conduit assembly (2) has a protrusion (23), and along the axial direction of the conduit assembly (2), the limiting member (32) is sandwiched between the protrusion (23) and the elastic retaining ring (33).

6. The compressor of claim 4, wherein, The valve core (31) has a U-shaped longitudinal section. The valve core (31) includes a bottom wall and a side wall located on the side of the bottom wall near the air outlet (22) of the duct assembly (2). The side wall of the valve core (31) has a connecting hole (311). When the valve core (31) opens the vent hole (321), the vent hole (321) is connected to the jet enthalpy enhancement hole through the connecting hole (311).

7. The compressor of claim 6, wherein, There is a clearance channel (24) between the inner wall of the conduit assembly (2) and the side wall of the valve core (31). When the valve core (31) opens the vent (321), the vent (321) is connected to the connecting hole (311) through the clearance channel (24).

8. The compressor of claim 4, wherein, The one-way valve assembly (3) further includes an elastic element (34) for applying an axial force along the conduit assembly (2) to the valve core (31) so that the valve core (31) blocks the vent (321).

9. The compressor of claim 8, wherein, The one-way valve assembly (3) further includes a guide (35), which is fixedly disposed inside the conduit assembly (2). The elastic member (34) is sleeved outside the guide (35), and the guide (35) is used to make the elastic member (34) move along the axial direction of the conduit assembly (2).

10. The compressor of claim 1, wherein, The compressor also includes a seal (4) which is disposed between the outer periphery of the conduit assembly (2) and the wall of the jet enthalpy-increasing orifice along the circumferential direction of the conduit assembly (2).
