Description
To the present invention relates to closed-type compressor, in particular, to relate to the noise that is inhaled into the refrigerant in the pressing chamber in order reducing, and the suction silencing apparatus is installed in the mounting structure of suction silencer of closed compressor of a side of cylinder head.
Fig. 1 has represented the internal structure of closed-type compressor in the prior art.As shown in Figure 1, the seal container 1 that constitutes the compressor outward appearance is made of upper container 1t and bottom container 1b, is provided with framework 2 in the inside of this seal container 1.Fixing stator 3 on this framework 2, framework 2 then is bearing in the inside of seal container 1 with spring 2S.
In addition, run through a bent axle 5 in the central authorities of said frame 2.Be provided with the rotor 4 that becomes one with it on this bent axle 5, this rotor 4 rotates with above-mentioned bent axle 5 by means of the electromagnetic action between stator 3.
In the upper end of above-mentioned bent axle 5, with the position of the rotating center off-centre of above-mentioned bent axle 5 on cam pin 5b is arranged.And, in a side relative counterweight 5c is arranged with forming above-mentioned cam pin 5b.Above-mentioned bent axle runs through the central authorities of framework 2 up and down, by this framework supporting, can rotate.
In addition, also has the grease channel (not shown) in the inside of above-mentioned bent axle.In above-mentioned grease channel, be provided with the pump that the lubricant oil that accumulates in seal container 1 bottom is aspirated up in the underpart of above-mentioned bent axle 5 and inhale the 5d of mechanism, inhaled lubricant oil that mechanism aspirates up by this pump and just be transported to the top of framework 2 and splash and come.
On the other hand, on said frame 2, be provided with the cylinder 6 that inside has been equipped with pressing chamber 6 ', in this pressing chamber 6 ', be provided with the piston 7 that moves by means of the rotation of bent axle 5.And, be provided with the valve assembly 9 that control flowed into and discharged the refrigerant of above-mentioned pressing chamber 6 ' at the front end of above-mentioned cylinder 6.Cylinder head 10 is installed on the valve assembly 9, sucks silencing apparatus 11 usefulness clips 12 and is installed on the cylinder head 10.This suction silencing apparatus 11 is connected with valve assembly 9, makes refrigerant can be transported in the above-mentioned pressing chamber 6 '.
Side at above-mentioned suction silencing apparatus 11 has formed the suction part 11 ' that refrigerant is transported to seal container 1 inside by the suction pipe (not shown).The entry shape of this suction part 11 ' as shown in Figure 2, its suction side is broader, and the inboard is narrower.Above-mentioned suction part 11 ' is relative with above-mentioned suction pipe, by above-mentioned suction pipe the refrigerant that is transported to seal container 1 inside is directly sucked in.
In addition, as shown in Figures 2 and 3, in above-mentioned suction silencing apparatus 11, also be provided with portion's flowing refrigerant within it is transported to the discharge section 11 that goes in the above-mentioned pressing chamber 6 ' ".Above-mentioned discharge section 11 " bending extension is to a side of above-mentioned suction silencing apparatus 11, is connected on the above-mentioned cylinder head 10 with clip 12.
Closed-type compressor with this structure is after connecting power supply, and by means of the electromagnetic action between above-mentioned rotor 4 and the stator 3, rotor 4 just can rotate with respect to stator 3, so above-mentioned bent axle also rotates together with rotor 4.When bent axle 5 rotated, the cam pin 5b that is on bent axle 5 eccentric positions just drew circle in rotation, make the piston 7 that is connected on the cam pin 5b make straight reciprocating motion, compression refrigerant in pressing chamber 6 '.
In this existing closed-type compressor, above-mentioned suction silencing apparatus 11 usefulness suction pipes suck its inside by the refrigerant that above-mentioned suction part 11 ' will suck from the outside, reduce after the noise, again by above-mentioned discharge section 11 " refrigerant is transported in the pressing chamber 6 '.
, when this clip 12 being set being pressed on the cylinder head 10, can produce following problem to suction silencing apparatus 11.
At first, in clip 12 being compressed the process that sucks silencing apparatus 11, worry and on above-mentioned suction silencing apparatus 11, to produce burr.Like this, if on suction silencing apparatus 11, produced burr, will make the reliability generation problem of compressor.
In addition,, suck silencing apparatus 11 and can produce trickle distortion, also can deform even suction silencing apparatus 11 was removed with being connected of cylinder head 10 in the above-described process of compressing into like that.
And, when assembling again after sucking silencing apparatus 11, will make the process of assembling complicated according to above-described like that clip 12 being compressed into.Here it is, for the clip 12 and the suction silencing apparatus 11 of assembled state are fixed together being in advance, must hold above-mentioned clip 12, again the operation that is fastenedly connected with bolt B respectively.
Therefore, the present invention provides a kind of assembling operation fast in order to solve existing problem in the prior art, to its objective is exactly, simply sucks the mounting structure of silencing apparatus.
For achieving the above object, comprise: be connected the cylinder head part on the compression member of compression refrigerant according to the mounting structure of the suction silencing apparatus of closed-type compressor with feature of the present invention; Be installed on the above-mentioned cylinder head part, the noise of refrigerant is reduced, refrigerant is transported to the suction silencing apparatus that above-mentioned compression member goes; And push down a side of above-mentioned suction silencing apparatus with the elastic force that recovers original form, it is fixed on fixed component on the above-mentioned cylinder head part.
On above-mentioned cylinder head part, allow the said fixing parts push down above-mentioned suction silencing apparatus in addition, carry out the predetermined fixed part of predetermined fixed.
Above-mentioned predetermined fixed partly is facing to the plane of inclination that is fixed on the suction silencing apparatus on the above-mentioned cylinder head part.
Above-mentioned predetermined fixed parts have the elasticity pressing part that is pressed into a side of above-mentioned suction silencing apparatus with elastic force in the central, have at the two ends of above-mentioned elasticity pressing part to be fixedly connected on the attachment portion of using on the above-mentioned cylinder head.
By means of the mounting structure that has according to the suction silencing apparatus of the closed-type compressor of this structure of the present invention, just can more promptly finish the installation exercise that sucks silencing apparatus, and also have and can not damage the advantage that sucks silencing apparatus in the installation process.
Below, describe embodiments of the invention in detail with reference to accompanying drawing.In the accompanying drawing:
Fig. 1 is the in-built sectional view of common closed-type compressor;
