Example two
In order to solve the above problem, embodiments of the present application provide another refrigerator with a low-noise compressor, where a muffler is disposed at an outlet of an exhaust pipe, and the muffler reduces the transmission energy of sound waves by utilizing the interference cancellation of the sound waves in the muffler, thereby reducing the exhaust noise.
The noise of the compressor includes the noise of the compressor starting and stopping, and the noise of the compressor high-frequency operation air suction and exhaust. As shown in fig. 6, when the compressor is operated, as the piston rotates in a reciprocating manner, intermittent exhaust noise is generated at the joint of the end of the inner exhaust pipe 5 and the outer exhaust pipe, and the most effective way to reduce the exhaust noise is to use a silencer, which is divided into a resistive silencer and a reactive silencer, wherein the resistive silencer is mainly used to reduce high-frequency noise, and the reactive silencer is mainly used to reduce ground mid-frequency noise. The exhaust noise belongs to the noise in a wide frequency band, so that the impedance compound muffler 6 is installed at the tail end of the exhaust pipe, and the exhaust noise of the suction and exhaust pipe 5 is reduced through the impedance compound muffler 6.
As shown in fig. 7 and 8, a perforated plate 61, a partition 63 and a through pipeline 66 are arranged in the impedance compound muffler 6, the perforated plate 61 is perpendicular to the inner exhaust pipe 5, and the perforated plate 61 is close to the inner exhaust pipe 5; the perforated plate 61 and the partition 63 are parallel to each other, and the partition is close to the outer distribution pipe. The pipe 66 penetrates the impedance compound muffler 6, and an inlet of the pipe 66 communicates with the inner exhaust pipe 5, and an outlet of the pipe 66 communicates with the outer exhaust pipe.
In this example, the perforated plate 61, the partition 63 and the pipe 66 divide the muffler cavity into a first cavity 60, a second cavity 62 and a third cavity 64, the first cavity 60 being close to the inlet of the muffler, the third cavity 64 being close to the outlet of the muffler; both the perforated plate 61 and the partition plate 63 are perpendicular to the pipeline 66, the perforated plate 61 divides the inner cavity of the pipeline 66 into a first inner cavity 65 and a second inner cavity 70, the first inner cavity 65 of the pipeline 66 is communicated with the inner exhaust pipe 5, and the second cavity 70 of the pipeline 66 is communicated with the outer exhaust pipe.

The line 66 is also provided with a return air opening 69, through which return air opening 69 the second cavity 62 can be brought into communication with a second interior chamber 70 of the line 66. The partition 63 is provided with a communication hole corresponding to the second inner cavity 70 of the pipeline 66, that is, the cavity of the pipeline 66 passes through the partition 63, so that the second inner cavity 70 is communicated with the outer exhaust pipe.
In this example, the perforated plate 61 may be provided with a through hole 68, and the through hole 68 is adjacent to the conduit 66 to communicate the first cavity 60 with the second cavity 62. A plurality of through holes may be spaced apart from the perforated plate 61 to accelerate the flow of gas between the first cavity 60 and the second cavity 62.
Thus, the gaseous refrigerant enters the first inner cavity 65 of the pipeline 66 from the inlet of the impedance composite muffler 6, then the gaseous refrigerant in the pipeline 66 enters the first cavity 60 from the first inner cavity 65 through the air outlet 67 on the pipeline 66, and after the refrigerant enters the first cavity 60 of the muffler, the flow rate of the refrigerant is reduced, and the energy is released for the first time; the refrigerant enters the second cavity 62 between the perforated plate 61 and the partition plate 63 through the through holes 68 distributed on the perforated plate 61, the flow rate of the refrigerant is reduced again after the refrigerant enters the second cavity 62, and the energy is released for the second time; the refrigerant then enters the second chamber of the line 66 through the return port 69 in the line 66 and exits through the outlet of the line 66. Therefore, after the refrigerant is subjected to energy release twice, the flow speed is reduced, and the noise is reduced, so that the exhaust noise at the outlet position of the air suction and exhaust pipe is reduced.
According to the refrigerator with the low-noise compressor, the impedance composite muffler is arranged at the outlet of the suction and exhaust pipe of the compressor, the refrigerant entering the muffler is subjected to multiple energy release through the space in the impedance composite muffler, namely, the interference of sound waves in the muffler is utilized to offset and reduce the transmission energy of the sound waves, so that the exhaust noise of the suction and exhaust pipe is reduced.
