Abstract
A muffler fixing device of the linear type compressor includes piston, which is set in the cylinder, makes straight reciprocating motion and absorbs, compresses and discharges the secondary refrigerant, muffler, whose hush pipe is set in the piston and fixed on one side of the piston; supporting part, which plugs up one side of the piston and crosses the hush pipe, and magnet, which adheres the supporting part to one end of the piston through the magnetic force and makes the supporting part move along the direction of the semidiameter of the piston in relation to the hush pipe. There is a hole in the middle of the supporting part, which keeps given distance with the hush pipe to avoid contacting with the hush pipe. The muffler set in the compressor can eliminate the noise caused by the piston when making straight reciprocating motion and compressing the secondary refrigerant gas. Even if the muffler is shaking, we still can correctly put the muffler in the middle of the piston, thus reduce the noise leakage and avoid the abrasion caused by the muffler and piston.

The process that hush pipe (62a) is inserted and secured on piston only (54a) is: be inserted under the state of piston only (54a) at hush pipe (62a), the front end of targeting part (74b) by damping device (76) by elastic support on the support end (75) of hush pipe (62a); Its rear end is supported in the anechoic chamber (62b).Described support end (75) is to give prominence at the outer surface of hush pipe front end to form.
Described damping device (76) is spiral winding spring (helical coil spring).It is characterized in that because can prevent noise leakage greatly, again because little and make it possible to move freely along the elastic force of radial direction along axial elastic force.
Also be provided with the damping device (78) of elastic material between supporting body (74a) and the targeting part (74b).The effect of described damping device (78) is: when piston (54) when radial direction moves, make hush pipe (62a) and targeting part (74b) be subjected to the buffering of supporting body (74a).Described piston (54) is movable with supporting body (74a).The described damping device (78) of annular shape (ring) is fixedly installed on perforation (h) inner peripheral surface of supporting body.
In addition, also be provided with reduction friction means (not shown) between supporting body (74a) and the targeting part (74b).The effect of described reduction friction means is: when piston (54) when radial direction moves, make piston (54) do straight reciprocating motion with the relative targeting part of supporting body (74a) (74b).Described reduction friction means is annular shape, and is fixedly installed on perforation (h) inner peripheral surface of supporting body.
Baffler (62) hush pipe (62a) is kept optimal spacing by damping device (76) and supporting part (74) with piston only (54a).Even so be subjected to external impact, hush pipe (62a) is when rocking, cushioned along axle direction and radial direction by above-mentioned damping device (76) and buffer unit (78), avoided hush pipe (62a) to touch targeting part (74b), thereby prevented that the situation that produces noise or wearing and tearing from taking place.And hush pipe (62a) is kept optimal spacing with piston only (54a), and the noise that has improved piston (54) inner space reduces effect.
In addition, the targeting part (74b) that forms at supporting part (74) central position twines part hush pipe (62a), makes targeting part (74b) break off noise, has improved noise and has reduced effect.
The effect of invention
The silencer fixing structure of aforesaid linear compressor of the present invention is because at an end of piston Fixedly run through the support component of muffler by magnet, make the hush pipe of muffler to insert the side of internal piston Formula is fixed. Even rock thereby be subjected to outside impact sound reduction device, hush pipe is also avoided bumping with other parts Touch, reduced noise and component wear.
In addition, the silencer fixing structure of linear compressor of the present invention is because fix at an end of piston Between hush pipe and support component, buffer unit is set when running through the support component of muffler, makes to disappear The hush pipe of sound device is fixed in the mode of inserting internal piston. Even thereby because outside impact sound reduction device Rock since buffer unit buffering and do not need special operation also can keep hush pipe and support component it Between optimal spacing, so can improve the effect that reduces noise by the internal piston space.
