The upper part of the main body 1 is provided with a discharge pipe 30 for guiding the flow of the refrigerant compressed in the cylinder member (13).

However, the accumulator 19 of the conventional compressor configured as described above has a problem in that noise is generated inside the accumulator 19 when the refrigerant flows, and a standpipe (inserted into the accumulator 19) There was a problem in that the warpage occurred in 25) and the compressor performance was degraded and abnormal noise was generated.

Therefore, the present invention is devised to solve the above-mentioned problems, and an object of the present invention is to reduce the noise generated by the flow rate of the refrigerant when the refrigerant is introduced into the accumulator or discharged through the standpipe. By improving the reliability of the product by preventing the bending of the stand pipe to form a smooth refrigerant flow path to provide a noise suppression device of the compressor to increase the noise reduction effect.

The noise preventing device of the compressor according to the present invention made to achieve the above object is a case member in which the liquid refrigerant and refrigerant gas evaporated in the evaporator is stored, and the standpipe for discharging the refrigerant gas in the introduced liquid refrigerant and refrigerant gas In the accumulator disposed is, extrapolated to the outer peripheral surface of the stand pipe, the noise generated when the liquid refrigerant and the refrigerant gas flows into the case member and the refrigerant gas introduced into the case member is sucked into the stand pipe It is characterized in that the noise prevention means for preventing the noise generated during the discharge of the refrigerant gas by preventing the noise generated at the same time, while preventing the bending of the stand pipe.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3.

FIG. 2 is a longitudinal sectional view schematically showing the configuration of the compressor according to the present invention, and FIG. 3 is a main part perspective view along arrow A-A of FIG. 2 showing the noise preventing means of the accumulator according to the present invention.

In addition, the same code | symbol is attached | subjected about the same part as FIG. 1, and the overlapping description is abbreviate | omitted.

As shown in FIG. 2, a main body 1 forming an external appearance of a compressor, a stator 3 positioned inside the main body 1 to form a magnetic field by receiving external power, and the stator 3 Rotor 5 is rotated by the influence of the magnetic field formed in the rotating shaft 9, the rotary shaft 9 is rotated in conjunction with the rotor 5, the eccentric shaft 7 is formed on one side, the eccentric shaft formed on the rotating shaft 9 Roller member 11, which is wound around (7) and performs rotational and sliding motion, upper flange 15 fixed to upper side of cylinder member 13, and lower portion fixed to lower side of cylinder member 13 The flange 17 is comprised.

An accumulator 19 is provided outside the main body 1 to separate the liquid refrigerant and the refrigerant gas so that only the refrigerant gas of the refrigerant evaporated in the evaporator is supplied to the compressor.

A pipe for guiding the flow of the refrigerant so that the liquid refrigerant and the refrigerant gas evaporated in an evaporator (not shown) is sucked into the case member 21 in an upper portion of the case member 21 forming the exterior of the accumulator 19. 23 is disposed, a stand pipe 25 is disposed below the case member 21 to guide the flow of the refrigerant gas so that the refrigerant gas is supplied to the cylinder member 13, and the stand pipe 25 is disposed. One side is connected to the suction pipe 27 for guiding the flow of the refrigerant so that the refrigerant is sucked into the cylinder member (13).

Noise generated when the refrigerant stored in the case member 21 is sucked into the suction pipe 27 by the stand pipe 25 and the bending of the stand pipe 25 are formed on the outer circumferential surface of the stand pipe 25. The first circular plate 31 and the second circular plate 33, which are noise preventing means 29, which prevent the occurrence of abnormal noise due to this occurrence, are extrapolated.

Insertion holes 31a and 33a into which the stand pipe 25 is inserted are formed at the centers of the first circular plate 31 and the second circular plate 33, and the insertion holes 31a and 33a are formed. Formed.

The first circular plate 31 on which the through hole 31b is formed is disposed at an approximately middle portion inside the case member 21, and the through hole 31b and the through hole 33b are centered on the stand pipe 25. The second circular plate 33 is disposed at a predetermined distance from the first circular plate 31 so as to be a position opposite to the first circular plate 31.

The upper part of the main body 1 is provided with a discharge pipe 30 for guiding the flow of the refrigerant compressed in the cylinder member (13).

Therefore, when the power is applied, a magnetic field is formed in the stator 3, and when the rotor 5 is rotated by the magnetic field formed in the stator 3, the compressor includes a rotating shaft integrally fixed to the rotor 5 ( As the 9 is rotated, the eccentric shaft 7 disposed on one side of the rotary shaft 9 also rotates at high speed in association with the rotary shaft 9.

The roller member 11, which is extrapolated to the eccentric shaft 7, rotates and reciprocates in the cylinder member 13 so that the refrigerant sucked through the suction pipe 21 formed at one end of the cylinder member 13 is removed. The high temperature and high pressure is compressed, and the high temperature and high pressure refrigerant is discharged to the outside of the upper flange 15 through an unshown discharge port formed at one side of the cylinder member 13.

The refrigerant discharged to the outside of the upper flange is moved upward along a guide passage (not shown), discharged to the outside of the compressor through a discharge pipe 30 provided on the upper body, and circulated by a known refrigerant cycle, and then the liquid refrigerant is Refrigerant gas included is introduced through the pipe 23 provided on the case member 21 of the accumulator (19).

The liquid refrigerant and the refrigerant gas introduced into the pipe 23 pass through the through hole 31b of the first circular plate 31 disposed in the center of the case member 21 along the solid arrow direction, and the through hole 31b. The refrigerant passing through the bottom surface of the case member 21 passes through the through hole 33b of the second circular plate 33 disposed in the lower and middle portions of the case member 21 at a predetermined distance from the first circular plate 31. Flows into wealth.

Refrigerant gas separated from the liquid refrigerant and the refrigerant gas introduced as described above is a through-hole 33b of the second circular plate 33 disposed in the middle of the case member 21 along the dotted arrow direction as shown in FIG. After passing through the through-hole 31b of the first circular plate 31 disposed at a predetermined distance from the second circular plate 33 to pass into the stand pipe 25.

At this time, the liquid refrigerant and the refrigerant gas passing through the through-holes 31b and 33b of the first circular plate 31 and the second circular plate 33 have a small passage area and face the center of the stand pipe 25. The through-holes 31b and 33b positioned so as to lower the refrigerant inflow and discharge speeds, and thus, the pressure pulsation is reduced to reduce the noise, and as the pressure pulsation is reduced as described above, the cylinder member 13 The pressure difference between the wands is reduced, thereby improving the compression efficiency of the compressor.

In addition, since the first circular plate 31 and the second circular plate 33 support the outer circumferential surface of the stand pipe 25 at predetermined intervals, abnormal noise is generated by preventing the stand pipe 25 from bending. Can be prevented.

As described above, the accumulator of the compressor according to the present invention attenuates noise generated when the refrigerant and the refrigerant gas are discharged and introduced into the accumulator to improve the reliability of the product and at the same time the pressure difference between the cylinder member. It is a very practical design to improve the efficiency of the compressor, and to prevent the stand pipe from bending, thereby eliminating abnormal noise and improving the quality.
