Description

Technical Field

[0001] The utility model relates to the technical field of compressor mufflers, in particular to a muffler for a compressor. Background Art

[0002] Due to the complex shapes of their components, high machining precision requirements, and significant process complexity, the development of connecting rod compressors was once limited, and they were replaced by sliding tube and rotary compressors in refrigerators and other small refrigeration equipment. However, in recent years, with the continuous development of the machinery industry, various technical improvements have been made to the structure of connecting rod compressors. Currently, connecting rod compressors have once again become the leading product in refrigerator compressors, and their overall demand has increased significantly.

[0003] In connecting rod compressors, the suction muffler plays a crucial role—it's responsible for the primary noise reduction of the compressor. However, due to the complex structure and cumbersome manufacturing of existing connecting rod compressor mufflers, the price of these compressors, and indeed the entire refrigeration system, remains high. Furthermore, existing connecting rod compressor mufflers also suffer from a narrow muffler range. Utility Model Content

[0004] The purpose of the utility model is to provide a compressor muffler with simple structure, small size and low cost.

[0005] The technical solution of the utility model for solving the above technical problems is: a silencer for a compressor, comprising a silencer shell, a partition plate vertically provided in the silencer shell for dividing its inner cavity into a left silencer chamber and a right silencer chamber, a connecting pipe horizontally passing through the partition plate on the upper part of the silencer shell, and notches are provided on both side walls of the connecting pipe; an air inlet is provided on the lower side wall of the left silencer chamber, and an air outlet is provided in the right silencer chamber.

[0006] As a further improvement of the present invention, an air outlet pipe is vertically provided on the partition plate, the air inlet end of the air outlet pipe is the air outlet connected to the right muffler chamber, and the air outlet end of the air outlet pipe passes through the muffler shell and extends above it.

[0007] As a further improvement of the present invention, the muffler housing includes an upper cavity cover and a lower housing, and the outlet end of the air outlet pipe passes through the upper cavity cover and extends above it.

[0008] As a further improvement of the present invention, the lower shell is an n-type structure.

[0009] As a further improvement of the present invention, an air intake pipe is vertically provided at the lower part of the left muffler chamber, and the lower end of the air intake pipe is connected to the air inlet.

[0010] As a further improvement of the present invention, two notches are provided on both side walls of the connecting pipe.

[0011] As a further improvement of the present invention, the two notches are arranged opposite to each other in an upper and lower direction.

[0012] As a further improvement of the present invention, the length of the connecting pipe located in the left muffler chamber is shorter than the length of the connecting pipe located in the right muffler chamber.

[0013] Beneficial effects

[0014] Compared with the prior art, the advantages of the compressor muffler of the utility model are:

[0015] The silencer uses the ports at both ends of the connecting pipe and the notches on the side walls on both sides of the connecting pipe to guide the flow direction of the noisy airflow, thereby shielding and reducing the noise by canceling out the noise interference, thereby reducing the overall noise of the compressor; and compared with the existing silencer equipment of the connecting rod compressor, the compressor itself has the advantages of small size and low cost.

[0027] Example

[0028] The specific implementation of the utility model is as follows Figure 1-5 As shown, a silencer for a compressor includes a silencer shell. A partition plate 3 is vertically provided in the silencer shell to divide its inner cavity into a left silencer chamber 6 and a right silencer chamber 7. The edges of the partition plate 3 are fixedly and sealedly connected to the inner wall of the silencer shell, so as to prevent gas from passing through the connection between the edge of the partition plate 3 and the inner wall of the silencer shell. Among them, a connecting pipe 4 is horizontally penetrated on the partition plate 3 on the upper part of the silencer shell, and the left silencer chamber 6 and the right silencer chamber 7 are connected through the connecting pipe 4. Notches 41 are provided on both side walls of the connecting pipe 4, and the notches 41 are square. In this embodiment, the length of the connecting pipe 4 in the left silencer chamber 6 is less than the length of the connecting pipe 4 in the right silencer chamber 7. At the same time, an air inlet is provided on the lower side wall of the left silencer chamber 6, and an air outlet is provided in the right silencer chamber 7. The gas enters the inner cavity of the muffler shell from the air inlet, passes through the left muffler chamber 6, the connecting pipe 4 and the right muffler chamber 7 in sequence, and then leaves the inner cavity of the muffler shell from the air outlet, thus completing the silencing.

[0029] In the muffler, the flow direction of the noise airflow is controlled by using the ports at both ends of the connecting pipe 4 and the notches 41 on the side walls of the connecting pipe 4. Figure 4The flow direction shown is guided, thereby achieving mutual interference of noise, shielding and reducing noise, and thus reducing the overall noise of the compressor. In addition, compared with existing suction mufflers for connecting rod compressors, this muffler also has the advantages of sophisticated structure, small size, and low cost.

[0030] To guide the direction of airflow from the air outlet out of the muffler housing, an air outlet pipe 11 is vertically mounted on the partition plate 3. This air outlet pipe 11 is integral with the partition plate 3. The air inlet end of the air outlet pipe 11 is the air outlet connected to the right muffler chamber 7, and the air outlet end of the air outlet pipe 11 extends through the muffler housing to the top thereof. Furthermore, to guide the direction of airflow from the air inlet into the muffler housing, an air inlet pipe 21 is vertically mounted on the lower portion of the left muffler chamber 6, and the lower end of the air inlet pipe 21 is connected to the air inlet.

[0031] Regarding the specific structure of the muffler housing, it comprises an upper chamber cover 1 and a lower housing 2. The outlet end of the exhaust pipe 11 extends through the upper chamber cover 1 and above it. The connection between the upper chamber cover 1 and the lower housing 2 is a conventional arrangement in the prior art and will not be described in detail here. In this embodiment, the lower housing 2 has an n-shaped structure.

[0032] In addition, regarding the specific arrangement of the notch 41, in this embodiment, two notches 41 are provided on both side walls of the connecting pipe 4, and the two notches 41 are arranged opposite to each other in an upper and lower direction.

[0033] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
