Problems solved by technology

However, the resonant cavity in this device is located inside the muffler, occupying part of the volume of the muffler, resulting in a decrease in the airflow entering the muffler, which affects the suction efficiency of the muffler, and then affects the performance of the compressor

Embodiment 1

[0028] This embodiment provides a new type of suction muffler for a refrigerator compressor, as attached Figure 1-3 As shown, the muffler chamber includes an upper chamber 1 and a lower chamber 2, and the upper chamber 1 and the lower chamber 2 are connected and communicated through a slot. The upper chamber 1 is provided with an air outlet pipe 3, and one side of the lower chamber 1 is arranged side by side with an air inlet pipe 1 4 and an air inlet pipe 2 7, which can simultaneously take in air. In rubber sleeve 13, wherein the length of air intake pipe one 4 air inlet is 3mm, and the width is 2.5mm; And the length 4.5mm of air intake pipe two 7 air inlets, wide is 1.5mm. The outlet of the intake pipe one 4 is provided with a partition one 8, and the middle of the lower chamber 2 is provided with a partition two 9, and the partition two 9 divides the lower chamber 2 into an expansion chamber one 10 and an expansion chamber two 11, and the expansion chamber one 10 communic...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 lies in that the noise cancellation frequency of the first Helmholtz resonance cavity 5 is 600 Hz, and the noise cancellation frequency of the second Helmholtz resonance cavity 6 is 1000 Hz.

Embodiment 3

[0034] The difference between this embodiment and Embodiment 1 lies in that the noise cancellation frequency of the first Helmholtz resonance cavity 5 is 800 Hz, and the noise cancellation frequency of the second Helmholtz resonance cavity 6 is 1300 Hz.

Abstract

The invention discloses a novel suction muffler for a refrigerator compressor, which comprises a muffler chamber, an air outlet pipe is arranged on the muffler chamber, and an air inlet pipe 1 and an air inlet pipe 2 are arranged side by side on one side of the muffler chamber, and the air inlet pipe 1 is arranged side by side. A partition is provided at the exit, and the air intake pipe runs through the partition and communicates with the muffler chamber. On both sides of the outlet pipe, there are Helmholtz resonance chamber 1 and Helmholtz resonance chamber 2 protruding upwards on the muffler chamber. The Helmholtz resonance chamber 1 is located above the intake pipe 1 and communicates with the intake pipe 2. , the second Helmholtz resonator is in communication with the anechoic chamber, and the anechoic frequencies of the first Helmholtz resonator and the second Helmholtz resonator are different. At the same time, a dividing plate can be arranged in the anechoic chamber to divide the anechoic chamber into two expansion chambers. The invention uses expansion noise reduction and resonance noise reduction in combination to achieve better noise reduction and noise reduction effects, can effectively eliminate 600-1000 Hz noise, and ensures that the performance of the compressor is not affected.

Description

technical field [0001] The invention belongs to the field of mufflers, and in particular relates to a novel suction muffler for refrigerator compressors. Background technique [0002] When the compressor is working, due to the characteristics of its working principle, there is inevitably noise influence. The noise of the compressor is generated in many ways, including airflow noise, mechanical noise and electromagnetic noise. Among them, the airflow noise is a main noise source of the compressor, and the noise is mainly caused by the high-pressure fluid pulsation discharged from the compression chamber. [0003] Chinese patent CN206668505U discloses a suction muffler for a refrigerator compressor. One end of the first horizontal intubation tube is connected to the primary expansion cavity, and the primary expansion cavity is connected to the secondary expansion cavity through the second horizontal intubation tube. The intubation tube and the second horizontal intubation tub...
