Abstract
The present invention discloses an anti-leakage device for a silencer of a rotary compressor. The present invention is arranged in the rotary compressor which is rotated by a crankshaft, and then the piston eccentrically rotates in a cylinder. The rotary compressor is arranged between a suction opening and an exhaust port of the cylinder to eccentrically rotate with the piston. The blades of the rotary compressor do rectilinear motion to the radius direction, and suck, compress and exhaust refrigerant gas. The silencer is arranged on an upper bearing. The contact part of the silencer and the upper bearing forms the concave-convex slot connection. The silencer is provided with a cover shell with thin wall, the shape is an annular and flat cylinder shape, and the middle of the annular and flat cylinder is provided with a hole. An annularly hollow cavity is formed in the cover shell, and the lower part of the cover shell is provided with an opening. A bulge is formed on the silencer, and is integrated with the silencer. A groove is formed on the upper bearing and is mutually matched with the bulge which is formed on the silencer. As the contact part of the silencer and the upper bearing forms the concave-convex slot contact, the present invention improves the sealing performance, and prevents refrigerant gas from leaking.

Background technique
The rotary compressor that generally is applicable to air conditioner etc. be with bent axle that electric structure portion combines on eccentric rotary-piston in conjunction with compression structure part, rotary-piston is rotated in the compression volume of circular cylinder that motion sucks, compression, discharging refrigerant.
As shown in Figure 1, rotary compressor in the past is by stator 6 and rotor 7 that electric structure portion is set in casing 1 inside, and the center of its rotor 7 is pressed into bent axle 9, and the compression structure part that the bottom of bent axle 9 is provided with suction, compression refrigeration gas constitutes.
Compression structure part comprises the circular cylinder 3 that is fixed on casing 1 inner peripheral surface; The upper and lower bi-side while bent axle 9 that is close to cylinder 3 connects wherein and supported upper bearing (metal) 4 and lower bearing 2; Be connected rotation on the bent axle 9, and the rotary-piston 8 of eccentric rotation in cylinder 3; Be crimped on the outer circumferential face of rotary-piston 8, be rotated the blade (not shown) of doing straight line motion when moving and cylinder 3 being divided into suction space and compression volume at rotary-piston 8.
Shown in Fig. 2,3, silencing apparatus 5 is installed on upper bearing (metal) 4, prevent the noise diffusion of compressor.The silencing apparatus of rotary compressor is anti-formula silencing apparatus, according to the principle of anti-formula silencing apparatus, comprises a plurality of cavitys, increases the noise transmission damage to reach, thereby reduces the purpose of noise.Silencing apparatus 5 is the thin-walled case, and profile is the middle porose oblate cylindricality of ring-type, the inner cavity that forms annular, and lower openings covers on the top of upper bearing (metal) 4.Penetrate the necked part of upper bearing (metal) 4 in the hole in the middle of the silencing apparatus 5, silencing apparatus 5 is screwed on upper bearing (metal) 4.Silencing apparatus 5 and upper bearing (metal) 4 are plane contact.
The above-mentioned working procedure of rotary compressor in the past is as follows:
Promptly, make the inner rotation of rotor 7 for stator 6 power supplies at stator 6, meanwhile bent axle 9 rotates and rotary-piston 8 eccentric rotation in cylinder 3, off-centre rotation with rotary-piston 8, refrigerant gas is drawn into the suction space of cylinder 3, and continue to be compressed to certain pressure, when the pressure of the compression volume of cylinder 3 surpasses high moment of pressure in the critical pressure ratio casing 1, the drain tap (not shown) that is installed in upper bearing (metal) 4 is opened, pressurized gas is discharged to casing 1 inside from compression volume, discharge gas and move to top, be discharged to the circulating frozen system through gas outlet pipe (DP) by the slit of casing 1 and stator 6 or the slit of stator 6 and rotor 7 etc.
But in aforesaid rotary compressor in the past, because silencing apparatus 5 and upper bearing (metal) 4 are plane contact, sealing is bad, and refrigerant gas leaks easily.
Summary of the invention
The present invention proposes in order to overcome the problem that exists in the above-mentioned rotary compressor in the past, and its purpose is to prevent that refrigeration agent from leaking from the contact position of silencing apparatus and upper bearing (metal).In order to reach purpose of the present invention, rotate and make rotary-piston at motor, bent axle in the eccentric rotation of cylinder interior, and make the off-centre rotation that gets involved between the suction port of cylinder and the relief opening with rotary-piston, do in the rotary compressor that straight-line blade sucked, compresses, discharged refrigerant gas to radial direction.The anti-leakage device of silencer of rotary compressor comprises the silencing apparatus that is installed on the upper bearing (metal), and silencing apparatus is the thin-walled case, and profile is the middle porose oblate cylindricality of ring-type, the inner cavity that forms annular, lower openings.The position that silencing apparatus contacts with upper bearing (metal) forms the tongue and groove contact, forms bump on silencing apparatus, and bump and silencing apparatus are integrally formed, form groove on upper bearing (metal).The present invention is owing to form the tongue and groove contact at the position that silencing apparatus contacts with upper bearing (metal), and sealing improves, and has prevented freezing medium leakage.
