Description
Technical field
The present invention relates to a kind of connection set of gas suction portion of closed rotary compressor.
Background technique
As shown in Figure 1, 2, motor (4) is equipped with in the inside of the seal container (1) of existing hermetic type compressor, motor (4) is made of rotor (2) and stator (3), the center of above-mentioned rotor (2) has vertically formed axis hole (2a), and the inside of axis hole (2a) has running shaft (5) to be pressed into and to be fixed therein.
The lower end of above-mentioned running shaft (5) has formed the eccentric part of one (6) with it, and a side of eccentric part (6) is equipped with compression structure part (12).This compression structure part (12) is made of cylinder (cylinder) (9) and upper and lower part bearing (bearing) (10) (11), wherein the inside of cylinder (9) has rotary-piston (rolling piston) (7) to insert wherein, and, can form in the inside of cylinder (9) and to be used for the compression volume (8) of compression refrigerant gas along with the rotation of rotary-piston (7).
Valve (valve) assembly (15) is equipped with in the outlet port of going up the exhaust port (10a) that forms at above-mentioned upper bearing (10), and the baffler (16) that is used for reducing exhaust noise is housed above the valve member (15).
In addition, a side of above-mentioned cylinder (9) is equipped with coupled logical liquid storage tank (accumulator) (17), and this liquid storage tank (17) can prevent that liquid refrigeration agent from flowing into cylinder (9).Discharge tube (18) is equipped with at the top of above-mentioned seal container (1), and the higher pressure refrigerant gas that is compressed after structural portion (12) is compressed can be by this discharge tube (18) row to the outside.
If connected power supply having on the existing closed rotary compressor of said structure, the rotor (2) of motor (4) will rotate so, and the running shaft (5) that meanwhile is installed on the above-mentioned rotor (2) also can rotate thereupon.
Rotation along with above-mentioned running shaft (5), eccentric part (6) that forms in running shaft (5) lower end and the rotary-piston (7) that is connected on the eccentric part (6) also can rotate, and so just the refrigerant gas of low-temp low-pressure that can the compression volume (8) that be inhaled into cylinder (9) is inner is compressed into the refrigerant gas of High Temperature High Pressure.
Can pass through valve member (15) through refrigerant compressed gas and discharge, be discharged to the inside of seal container (1) then via the through hole (16a) of baffler (16).The refrigerant gas of the High Temperature High Pressure of these discharges can flow through the slit between rotor (2) and the stator (3), is discharged to the outside by discharge tube (18) at last.
The connection set of the gas suction portion of aforesaid existing hermetic type compressor as shown in Figure 2, formed connection protuberance (1a) on the seal container (1), funnel shaped suction connector (suctionadapter) (20) is fixed on this and connects on the protuberance (1a), suction assembly (suction assy) (21) is fixed on the inside that sucks connector (20), and suction tude (inlet tube) (22) is inserted and secured on the inside of suction assembly (21).The inside end of suction tude (22) is inserted in the inflow entrance (9a) of cylinder (9), and between the inflow entrance (9a) of the end of suction tude (22) and cylinder (9) seal ring (collar) (24) is housed.The L shaped pipe of liquid storage tank (23) is inserted and secured on the inside of the other end of suction tude (22).
Here, the connection protuberance (1a) of above-mentioned seal container (1) couples together by weld part (30) with sucking connector (20), and this weld part (30) is that method with projection welding (projectionweld) is welded.Suck between connector (20) and the suction assembly (21) and couple together, and this weld part (31) is that method with silver soldering (silver soldering) is welded by weld part (31).Couple together by weld part (32) (33) between suction assembly (21) and suction tude (22) and suction tude (22) and the L shaped pipe of liquid storage tank (23), and above-mentioned weld part (32) (33) is that method with brazing (copper barzing) is welded.
In the connection set of the gas suction portion of aforesaid existing closed rotary compressor, suction assembly, suction tude, the L shaped pipe of liquid storage tank all are made of copper, thereby material cost is higher.Particularly the interior tissue of the L shaped pipe of liquid storage tank material when welding can expand because of being heated, thereby the reliability of compressor is reduced.
In addition, the connection set of the gas suction portion of existing rotary compressor inserts suction tude and also want the indentation sealing circle afterwards, thereby assembling procedure is too much in assembling process; In welding process, also need to adopt multiple welding methods such as projection welding, silver soldering, brazing, therefore there are problems such as complex procedures, technical difficulty height and expense height.
Particularly the L shaped pipe of liquid storage tank the time is heated and is vibrated during compressor operation etc. under the influence of factor in welding, and its reliability can reduce greatly.
