Fig. 3 is the viewgraph of cross-section of explanation according to the bottom of compressor of the present invention, has shown the refrigeration agent that flows in the compressor.
Embodiment
Be elaborated now with reference to illustrative of the present invention, non-limiting example, its example shows in the accompanying drawings.The present invention is described in detail with reference to the accompanying drawings.In example embodiment, Linearkompressor will describe as an embodiment of compressor.
With reference to Fig. 2, Linearkompressor 20 according to the present invention comprises pent container 24, be used for sucking refrigeration agents and after compressed refrigerant, discharging the compression member of described refrigeration agent from pent container 24, and the drive part that compressive force is offered compression member.
Compression member is provided with the cylindrical cylinder body 29 that has within it the compression chamber 29a that limits, and the rod piston 31 that has among the compression chamber 29a of cylinder block of being arranged on 29 is reciprocal with lower linear in compression chamber 9a.Cylinder block 29 supports by supported spring 25.
Have to be limited to wherein and be set on the downside of cylinder block 29 with the cylinder head 30 that compressed refrigeration agent is discharged into outside release chamber 30a refrigeration agent be drawn into the introducing chamber 30b among the compression chamber 29a and be limited to wherein.In addition, cylinder block 30 is at the cooling fin 36 that is provided with on the lower surface in the oil that flows at least one bottom that extends to the container 24 of closing.Improving heat exchange efficiency, and a plurality of cooling fin can be arranged under the lower surface of cylinder head 30 cooling fin 36 by the metallic material manufacturing.Valve assembly 34 is arranged between cylinder head 30 and the cylinder block 29, and has introducing valve 34a and relief valve 34b in predetermined direction opened/closed, and the guiding refrigeration agent is with flow consistently in predetermined direction (referring to Fig. 3).
In addition, cylinder head 30 is provided with on a side and discharges silencing apparatus 39, and is provided with the suction silencing apparatus 38 of coupling on an other side.
For this purpose, muffler cover 39b is fixed to a side of cylinder head 30.In addition, refrigerant passage 37 is formed between the inside that discharges chamber 30a and discharge silencing apparatus 39 to discharge chamber 30a and to discharge connection between the silencing apparatus 39.Noise from compression chamber 29a is removed, simultaneously by being limited to the fluid passage that discharges in the silencing apparatus 39.Pipe 39a from the outside that discharges silencing apparatus 39 and extend to compressor 20 with will be by discharging the outside that refrigeration agent is directed to compressor 20 that is compressed of silencing apparatus 39.It is integrally formed with cylinder head 30 to discharge silencing apparatus 39, and discharging silencing apparatus 39 and cylinder head can for example be formed by aluminium.Discharging silencing apparatus 39 separates from cylinder block 29 within a predetermined distance.
Drive part is provided with stator 32 and mover 23, produces electromagnetic force therebetween with reciprocating piston 31 in cylinder block 29.Stator 32 comprises: outer core 32a, described outer core are provided with coil 35 in it, and the electric power when preset frequency is applied to coil 35 like this, and magnetic flux changes according to electric power; Inner core 32b, described inner core 32b are positioned on the position for the outer core 32a of mover 23.Stator 32 supports by keeping framework 33 and cylinder block 29.
Mover 23 has the cylindrical shape of closed upside, and is provided with annular permanent magnnet 28 to produce electromagnetic force between stator 32 and mover 23 in the space between core 32a and the inner core 32b outside on downside.Piston 31 is fixed to the center of the top part of mover 23 in the upper end, and reciprocal with mover 23.
Leaf spring 22 is fixed to the top part of mover 23 by bolt 23a, and by mover 23, leaf spring 22 has the core that is fixed to mover 23 simultaneously, and the peripheral part that is fixed to the upper end that keeps framework 33.
Operation with compressor of this spline structure describes with reference to Fig. 3.
At first, when the cooperation of piston 31 by stator 32 and mover 23 moves up, be incorporated into refrigeration agent in the compressor 20, be directed to then among the introducing chamber 30b of cylinder head 30 by sucking silencing apparatus 38.Be directed to the introducing valve 34a that the refrigeration agent of introducing chamber 30b passes through valve assembly 34, be directed to then among the compression chamber 29a.
Then, when the cooperation of piston 31 by stator 32 and mover 23 moved down, the refrigeration agent among the compression chamber 29a was compressed, and was discharged into then to discharge chamber 30a after the relief valve 34b by valve assembly 34.
Be discharged into the high temperature, the high-pressure refrigerant that discharge among the 30a of chamber and be incorporated into the fluid passage that discharges in the silencing apparatus 39, be discharged into the outside by being arranged on the pipe 39a that discharges in the silencing apparatus 39 then by the refrigerant passage 37 that is formed in the cylinder head 30.
At this moment, owing to the release silencing apparatus 39 that is provided to cylinder head 30 rather than cylinder block 29 by the refrigeration agent of its high temperature, high pressure, the heat that discharges silencing apparatus 39 is avoided directly being transferred to cylinder block 29.
In addition, cylinder head 30 is transferred to oil with the heat that is set to the release silencing apparatus 39 on the cylinder head 30 by the cooling fin 36 that is formed on the cylinder head 30, and the heat that is transferred to oil is transferred to the outside of compressor 20 by the container 24 of closing.Like this, be prevented from being transferred to the compression chamber 29a that is formed in the cylinder block 29 by cylinder head 30 and the heat that is set to the refrigeration agent of the release silencing apparatus 39 on the cylinder head 30.
From clearly above-mentioned, compressor according to the present invention prevents to be transferred to compression chamber by the heat of the refrigeration agent that discharges the chamber, prevents the reducing of efficient of compressor thus.
Although present invention has been described with reference to preferred embodiments, those of ordinary skill is appreciated that under the situation that does not deviate from the spirit and principles in the present invention and can makes amendment and change the present invention that its scope is limited by appended claims.
