Embodiment
Now, will the embodiments of the invention that the example shows in the accompanying drawings be described in detail, wherein same numeral is represented components identical.
Fig. 1 is the sectional view according to closed compressor of the present invention.With reference to Fig. 1, closed compressor of the present invention comprises: be arranged on the compression unit 20 of can 10 inside with compressed refrigerant; With the driver element 30 that produces drive compression unit 20 required drives.
This compression unit 20 comprises: the cylinder body 21 of determining pressing chamber 21a in inside; With at the reciprocates inside of pressing chamber 21a piston 22 with suction, compression and refrigerant emission.Cylinder cap 23 is set at an end of cylinder body 21 in opposed facing mode.Suction chamber 23a and drain chamber 23b have been determined in these cylinder cap 23 inside.Valve cell 24 is communicated with selection between the pressing chamber 21a to realize suction chamber 23a or drain chamber 23b between cylinder body 21 and cylinder cap 23.
Fig. 2 and Fig. 3 are the planimetric map that be arranged on vent silencer in closed compressor and the sectional view of expression according to first embodiment of the invention.With reference to Fig. 2 and Fig. 3, be set at least one end place at the two ends of cylinder body 21 according to the vent silencer 40 of first embodiment of the invention, and suitable weakening just is being discharged out the noise of the refrigeration agent of compressor.This vent silencer 40 has: the recessed silencer body of determining in cylinder body 21 50; With the baffler lid 60 that covers silencer body 50.
When baffler lid 60 covered baffler 50, it had determined to weaken the space of the pulsation of refrigeration agent.In current embodiment, baffler lid 60 has the central fixed projection 61 that extends to the bottom surface of silencer body 50 from surface, its underpart.The bottom surface of fixed projection 61 relative silencer bodies 50 is fixing firmly baffler lid 60 is connected with silencer body 50.In this case, the bottom surface of silencer body 50 is formed with fixed swage 54, is inserted into and is fixed therein with the stub area that allows fixed projection 61.Fully fit into fixed swage 54 in order to ensure fixed projection 61, the edge part 55 of annular protrusion also is formed on the bottom surface of silencer body 50 and sentences definite fixed swage 54.The edge part 55 of annular protrusion thinks that to the suitable distance of upper process fixed swage 54 provides enough degree of depth.
For the baffler lid 60 that improves connection and the sealing effect between the silencer body 50, liner 70 is between baffler lid 60 and silencer body 50.
Simultaneously, fixed projection 61 can be forced to ground pressure and fit into fixed swage 54, or can be screwed into fixed swage 54 as shown in Figure 4.The back one situation in, fixed projection 61 is provided with first 61a of screw portion at its excircle place, and fixed swage 54 within it portion's circumference be provided with the second screw section 54a corresponding with the first screw section 61a.
With reference to Fig. 5, discharge pipe 80 is assembled in the baffler lid 60, is discharged out compressor with the refrigeration agent that allows to have reduced its pulsation in vent silencer 40 through discharge pipe 80.In this case, discharge pipe 80 is fitted into the elongated cooperation thorax hole 62 that begins to extend through fixed projection 61 from the upper end of baffler lid 60.In order to be communicated with between the inside of discharge pipe 80 and vent silencer 40, discharge pipe 80 has first intercommunicating pore 81 at its a certain circumferential location; And that fixed projection 61 has is 81 corresponding with first intercommunicating pore, at second intercommunicating pore 63 of its a certain circumferential location.
With reference to Fig. 6, baffler lid 60 can further have a pair of spacer 64 that extends to the bottom surface of silencer body 50 from the lower surface of baffler lid 60 downwards.Spacer 64 is positioned in the opposite side place of fixed projection 61, and its terminal bottom surface with silencer body 50 is left.This arrangement is compressed when allowing space that refrigeration agent determines between the bottom surface through the end of spacer 64 and silencer body 50 and spreads, thereby weakens the refrigeration agent pulsation effectively.
Existing, with the general operation of explanation according to closed compressor of the present invention.
When driver element 30 was energized, rotor 32 rotated simultaneously with running shaft 30.The rotation of running shaft 33 causes piston 22 in pressing chamber 21a reciprocates inside, thereby makes refrigeration agent be inhaled into pressing chamber 21a from the suction chamber 23a of cylinder cap 23, and is compressed in pressing chamber 21a.After this, according to the to-and-fro motion of piston 22, compressed refrigerant is discharged into the drain chamber 23b of cylinder cap 23 through valve cell 24.
Next, through the guide groove of determining in cylinder body 21 25, the refrigeration agent that is discharged into drain chamber 23b is imported into the inlet 51 of silencer body 50.Like this, in the present invention covered for 60 fastening connections and in the vent silencer 40 that forms, the pulsation of refrigeration agent can be weakened, and is discharged out compressor at last by silencer body 50 and baffler.
Can see significantly that from foregoing description closed compressor according to the present invention comprises vent silencer, wherein the baffler Gai Jing fixed projection that is integrally formed in baffler lid place is connected to silencer body fastenedly.Adopt this structure, just need not to be provided with connection baffler lid and the required optional feature of silencer body such as screw and packing ring.This has the effect of simplifying total manufacture process and reducing the compressor manufacture cost.
Though illustrated and described one embodiment of the present of invention, those skilled in the art will recognize: under the situation that does not deviate from principle of the present invention and spirit (its scope is limited by claim and doctrine of equivalents), can change to present embodiment.
