Embodiment Construction

[0027] Figure 6 The discharge muffler device of the airtight rotary compressor according to the preferred embodiment of the present invention is shown. Figure 7 Is along Figure 6 The cross-sectional view of line V-V shows the main part of the phase changing device in detail, which is the main aspect of the present invention. In the drawings, the reference numeral 110 denotes the main body of the silencer, and the reference numeral 120 denotes the phase changing device.

[0028] As shown in the figure, the muffler main body 110 includes a skirt 112 which extends downwardly along the circumference of the muffler main body 110. Such as figure 1 As shown, the muffler main body 110 is disposed above the upper flange 32 where the discharge port 33 is opened. Therefore, a noise reduction space is formed between the main body 110 and the upper flange 32. In addition, a pair of discharge openings 114 are opened on the main body of the noise reduction device for discharging the refrige...

Abstract

A discharge muffler of a hermetic rotary compressor has a simple structure, and reduces the noises which occur due to pulsation of refrigerant and impact to a valve when the refrigerant, which is compressed in an inner space of a cylinder of the compressor, is discharged. The discharge muffler includes a muffler body which is disposed above an upper flange to define a noise reducing space with the upper flange, and has a pair of discharge openings through which the refrigerant, which is discharged to the noise reducing space, is discharged, and a phase varying means for preventing the noises which occur due to the pulsation of the refrigerant and the impact to the valve which is disposed at the discharge port, from being discharged together with the refrigerant. The phase varying means also functions to vary the phases of the noises and to counterbalance the noises. The phase varying means comprises a pair of covers which extend from the muffler body toward centers of the discharge openings to cover approximately half portions of the discharge openings from above and from below, respectively, in an alternating pattern. Accordingly, the noise, which is produced when the refrigerant is discharged, is blocked by a pair of covers which are disposed at the discharge openings, and the phases of the noises are varied, so that the noises are counterbalanced. As a result, the great noise reduction effect is guaranteed with a simple structure.

Description

Technical field [0001] The invention relates to an airtight rotary compressor, which is used to form a refrigeration cycle of air conditioners, refrigerators and the like. More specifically, the present invention relates to a discharge muffler device that can reduce the noise generated by the pulsation of the refrigerant and the impact on the valve when the refrigerant compressed by the cylinder is discharged. Background technique [0002] Generally speaking, the air-tight compressor includes: a compression device; a motor used to drive the compression device, the motor is installed in a sealed box. According to the working mode of the compression device, air-tight compressors can usually be divided into reciprocating, scroll and rotary. [0003] figure 1 One of these compressors, a rotary compressor, is shown. Compared with its simple structure, the performance of this compressor is superior. [0004] figure 1 It is a vertical sectional view of a prior art airtight rotary co...
