Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a compressor noise reduction structure. Background Technology

[0002] Car refrigerators have become one of the mainstream car appliances that have gradually become popular in recent years. However, the compressor needs to continuously draw in and exhaust air, especially low-pressure continuous air intake, which will generate a lot of airflow noise. Therefore, a muffler is needed at the air intake end to reduce noise generation. However, due to the size limitation of the compressor itself, the external volume of the muffler is limited. At the same time, in order to ensure the strength of the muffler itself, the internal volume for gas flow is mostly small, making it difficult to achieve a good noise reduction effect. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed compressor silencing structure that addresses the defects and shortcomings of the existing technology and solves the aforementioned defects.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it includes a muffler body, the shape of which matches the installation position of the compressor, and a cavity is formed inside it. The cavity is divided into a first chamber and a second chamber by a partition plate. The two chambers are connected. An air inlet is provided at the bottom of one side of the muffler body and is connected to the first chamber. An air outlet is provided at the top of the muffler body and is connected to the second chamber.

[0005] Preferably, the partition plate is T-shaped, with the bottom of the vertical part of the T connected to the side wall of the cavity to form a partition, and the horizontal part forming a flow channel with the other side of the cavity.

[0006] Preferably, the muffler body has a vertical air guide chamber at the top, the air outlet is connected to the top of the air guide chamber, and the bottom of the air guide chamber is connected to the intersection of the horizontal and vertical "T"-shaped partition plates inside the second chamber.

[0007] Preferably, the bottom of the muffler body has two oil drain holes, located at the bottom of chamber one and chamber two respectively, and the bottom of the muffler body has a rim, which is located outside the two oil drain holes.

[0008] The beneficial effects of this utility model after adopting the above structure are: This application has a simple structure. It opens a cavity inside the muffler and forms two chambers through a partition plate, thereby maximizing the volume of the intake chamber without changing the external volume of the muffler and ensuring the muffler effect.

[0009] This application includes drain holes in both chambers to ensure that any oil that accidentally enters the muffler can be drained in time, preventing oil buildup. A surrounding edge is also designed to prevent oil from being sucked back or flowing along the muffler surface to other locations. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] See Figures 1-6 As shown, it includes a muffler body 1, the shape of which matches the compressor mounting position, such as... Figure 2 The muffler body 1 is installed behind the valve plate mounting seat 3 inside the compressor, in front of the rear mounting part 2, and is pressed tightly by the rear mounting part 2. The muffler body 1 forms a cavity inside, which is divided into chamber 1 6 and chamber 2 7 by the partition plate 5. The two chambers are connected. The bottom side of the muffler body 1 has an air inlet 4, which is connected to chamber 1 6. The top of the muffler body 1 has an air outlet 9, which is connected to chamber 2 7. After being installed in the compressor, the air outlet 9 fits with the air inlet hole of the valve plate in the valve plate mounting seat 3. The partition plate 5 is "T" shaped. The bottom of the vertical part of the "T" is connected to the side wall of the cavity to form a division, and the horizontal part forms a flow channel with the other side of the cavity. The top of the muffler body 1 has a vertical air guide chamber 8. The air outlet 9 is connected to the top of the air guide chamber 8. The bottom of the air guide chamber 8 is connected to chamber 2 7. The horizontal and vertical intersection of the "T" shaped partition plate 5 is located at the top of the muffler body 1.

[0014] By designing the partition plate 5, the overall strength of the hollow muffler is enhanced on the one hand, and the internal volume of the two chambers is increased on the other hand, improving the muffler effect and reducing noise generated by air intake; Figure 5 From the perspective, after the gas enters from the left air inlet 4, it flows through chamber 1 6, then through the upper flow channel, enters chamber 2 7, and then goes down to the leftmost side of chamber 2 7, and then exits from the air guide chamber 8 through the air outlet 9, ensuring that the airflow is forced through the two chambers.

[0015] At the bottom of the muffler body 1, there are two oil drain holes 10, located at the bottom of chamber 6 and chamber 7 respectively. The bottom of the muffler body 1 is provided with a rim 11, which is located outside the two oil drain holes 10.

[0016] An oil drain hole 10 is provided to ensure that when the compressor angle is tilted and oil accidentally enters the muffler, the oil can flow out through the oil drain hole 10 after the compressor angle is straightened. The surrounding edge 11 can ensure that the oil can be discharged in time after it flows out, preventing it from being sucked back or flowing to other places along the bottom of the muffler.

[0017] The installation, connection, or setting methods of the components not detailed above are all common mechanical methods, and the specific structure, model, and coefficient indicators of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.
