Description

Technical Field

[0001] The present application relates to the technical field of scroll compressors, and in particular to a muffler device for a scroll compressor and a scroll compressor. Background Art

[0002] Scroll compressors are widely used in refrigeration systems due to their large cooling capacity and low vibration. With the development of technology and increasingly fierce market competition, the speed requirements for compressors are also increasing, from 130rps to 160rps or even higher. In addition, the displacement of scroll compressors continues to increase, which leads to a gradual increase in the exhaust speed in the compressor, causing the compressor noise to continue to increase. Compressor noise is mainly divided into pneumatic noise, electromagnetic noise and mechanical noise. As the compressor speed and displacement increase, the refrigerant flow rate increases rapidly, and the gas exhaust speed increases, especially after the scroll compressor has intermittent exhaust, which intensifies the exhaust pulsation (the structure of the scroll compressor increases with the increase in speed and the intermittent exhaust characteristics unique to the moving plate, so that the refrigerant gas presents intermittent exhaust, which will cause a large pressure pulsation inside the compressor, causing the pneumatic noise inside the compressor to gradually increase with the increase in speed).

[0003] The traditional compressor layout usually reduces the exhaust flow velocity by designing the cavity volume at the top of the compressor to reduce the compressor pulsation. However, the compressor is limited by the overall height, and the cavity volume cannot increase with the speed, so the aerodynamic noise will increase with the increase of displacement and speed, affecting the normal use of the scroll compressor.

[0004] Therefore, it is necessary to design a muffler for a scroll compressor to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0028] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the embodiments of the present application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] According to a first aspect of the present invention, there is provided a muffler for a scroll compressor, Figures 1 to 7 As shown, the scroll compressor silencer is used for the scroll compressor, which can change the flow characteristics of the gas, dissipate the energy of the gas, reduce the pressure pulsation of the gas, and thus effectively reduce the pneumatic noise of the scroll compressor. The scroll compressor silencer includes a first silencer space 1 and a second silencer space 2.

[0033] In the following description, reference will be made to Figures 1 to 7 The detailed structures of the first silencing space 1 and the second silencing space 2 of the silencing device for a scroll compressor will be described in detail.

[0034] like Figure 1 , Figure 3 and Figure 5 As shown in the figure, the three figures respectively show the structure of the muffler for the scroll compressor in the front view, the structure in the top view and the structure in the bottom view. It can be seen from the figure that the muffler for the scroll compressor includes a main body formed into a cylindrical structure and a circular outer edge for installation and connection, and the circular outer edge is arranged on the outer peripheral side of the bottom of the main body. The main body formed into a cylindrical structure can facilitate the flow of gas and dissipate energy of the gas when it flows.

[0035] Furthermore, if Figure 2 As shown, in the embodiment, the main body of the muffler device for the scroll compressor includes a first muffler space 1 and a second muffler space 2, and the second muffler space 2 can be arranged on the upper part of the first muffler space 1, where the upper part refers to Figure 2 In this way, the main body of the muffler device for the scroll compressor can be formed into a structure with a double-layer muffler space to facilitate receiving gas and reserving enough space for gas flow.

[0036] Furthermore, if Figure 4 and Figure 5As shown, in the embodiment, the first silencer space 1 and the second silencer space 2 can be separated by the first baffle plate 3, the first baffle plate 3 can be formed into a disc-shaped structure, the middle of the disc-shaped structure is provided with a first guide portion 4, and the periphery of the disc-shaped structure is provided with a second guide portion 5. When the silencer device for the scroll compressor is in use, the first silencer space 1 is connected to the exhaust channel of the fixed plate 10 described below, and can directly receive the gas from the fixed plate 10. After the gas enters the first silencer space 1, it enters the second silencer space 2 through the first guide portion 4 and the second guide portion 5 of the first baffle plate 3. Compared with a single air intake, the gas that enters the second silencing space 2 through two passages divided by the first guide portion 4 and the second guide portion 5 can be distributed more evenly, so that the gas can be distributed more quickly and evenly in the second silencing space 2, thereby increasing the exhaust speed and further dissipating the energy of the gas, thereby reducing aerodynamic noise; in addition, if a single air intake is used, the gas needs to move around the lower part of the first baffle 3 before it can be discharged, so passages are opened in the middle and outer peripheral sides of the first baffle 3 to reduce the exhaust resistance.

[0037] Furthermore, if Figure 3 and Figure 4 As shown, in the embodiment, an exhaust hole 6 is provided at the top of the second silencing space 2. After the gas enters the second silencing space 2, it is silenced by the silencing structure of the second silencing space 2 and then discharged from the exhaust hole 6. The silencing structure of the second silencing space 2 may include a plurality of chambers. Specifically, the interior of the second silencing space 2 is divided into a plurality of chambers by a diaphragm 7. Two adjacent chambers are separated by a diaphragm 7. In order to ensure that the gas has sufficient flow space, the diaphragm 7 does not completely isolate these chambers, but forms these chambers into spaces with openings, that is, the first end of the chamber is close to the first guide portion 4, and the gas flowing out through the first guide portion 4 can enter the interior of these chambers. In addition, the second guide portion 5 is located at the second end of the chamber, and the gas flowing out through the second guide portion 5 enters these chambers from the other end. The gas entering these chambers through the first guide portion 4 or the second guide portion 5 passes through these chambers, so that the energy of the gas is lost, and then discharged from the exhaust hole 6 located at the top.

[0038] The muffler device for the scroll compressor can perform secondary muffler on the gas through the cooperation between the first muffler space 1 and the second muffler space 2, and the specially designed second muffler space 2 can effectively consume the energy of the gas, thereby reducing the aerodynamic noise. By using the muffler device, the aerodynamic noise of the scroll compressor can be significantly reduced, especially when running at high speed, the aerodynamic noise problem caused by gas pulsation can be solved, and it is suitable for scroll compressors with large displacement; because the muffler device will not change the original structure of the scroll compressor, it can greatly reduce the noise of the scroll compressor without reducing the energy efficiency of the scroll compressor, improve the sound quality of the scroll compressor, and thus enhance the product competitiveness of the scroll compressor.

[0039] Preferably, if Figure 4 As shown, in the embodiment, the upper surface of the first baffle 3 is taken as a plane, and the size of the orthographic projection of the chamber on the plane gradually decreases from the second end to the first end. As mentioned above, the first baffle 3 is formed into a disc-shaped structure in order to correspond to the main body formed into a cylindrical structure. Figure 4 As shown in the cross-sectional view, a plurality of chambers are sequentially arranged along the circumferential direction of the first baffle 3, and two adjacent chambers are separated by a partition 7. The first end of the partition 7 is arranged in the middle of the disc-shaped structure, and the second end of the partition 7 is arranged at the periphery of the disc-shaped structure. There is a certain distance between the first ends of two adjacent partitions 7, and this distance can be used to receive the gas from the first guide portion 4 so that the gas can flow to the interior of the chamber. In this way, each chamber can be formed into a nearly fan-shaped structure due to the separation of the partition 7, and the size of the second end of the fan-shaped structure (i.e., the end close to the periphery of the disc-shaped structure) is larger than the size of the first end of the fan-shaped structure (i.e., the end close to the middle of the disc-shaped structure). The cross-sectional area of ​​the cavity formed into a fan-shaped structure in this way gradually decreases, so that the gas can form a vortex at the outlet position of the fan-shaped structure (the first end of the fan-shaped structure) for noise elimination (the movement trajectory of the airflow can be seen in FIG. 2 ). Figure 7 ).

[0040] Preferably, if Figure 2 and Figure 4 As shown, in an embodiment, the second silencing space 2 may further include a second baffle 201, which is disposed inside the second silencing space 2, and the second silencing space 2 is divided into a first exhaust chamber 202 and a second exhaust chamber 203 by the second baffle 201. The second baffle 201 may be perpendicular to the first baffle 3, and the second baffle 201 divides the second silencing space 2 into two left and right parts. Further, the first exhaust chamber 202 and the second exhaust chamber 203 may each include a plurality of chambers, a first guide portion 4 and a second guide portion 5. In this way, the gas may flow separately in the first exhaust chamber 202 and the second exhaust chamber 203, respectively, to achieve more efficient silencing, and to adapt to a large-displacement scroll compressor running at high speed.

[0041] Preferably, if Figure 2 and Figure 4 As shown, in the embodiment, the muffler device for the scroll compressor further includes a guide cover 9, which is arranged on the first guide part 4, and the guide cover 9 covers part of the first guide part 4. The guide cover 9 can be formed into a hemispherical structure, and covers part of the first guide part 4, and the "covered part" here can be understood as: in order to enable the first guide part 4 to flow out gas and need to control the flow direction of the gas, the guide cover 9 is installed on the first guide part 4, so that the gas can only flow out from a specific direction.

[0042] Preferably, if Figure 2 , Figure 4 and Figure 5 As shown, in an embodiment, the first guide portion 4 may include a plurality of first guide holes 401, each of the first guide holes 401 is covered with a guide cover 9, and the opening directions of two adjacent guide covers 9 are different. In order to meet the demand for sufficient flow, the number of the first guide holes 401 is four in the embodiment, and more may be opened, which is not limited here. The four first guide holes 401 are arranged in groups of two, respectively, in the first exhaust chamber 202 and the second exhaust chamber 203. The four first guide holes 401 are each covered with a guide cover 9, and the opening directions of the four guide covers 9 are different, so that the directions of the gas flowing out of the four guide covers 9 are different, so that the gas can move evenly to multiple chambers.

[0043] Preferably, if Figure 2 As shown, in the embodiment, the second silencing space 2 includes a vertical direction (the vertical direction here can be understood as Figure 2 The first accommodating portion 204 and the second accommodating portion 205 are arranged in the direction from bottom to top or from top to bottom in the figure, the air guide 9 is arranged in the first accommodating portion 204, the diaphragm 7 is arranged in the second accommodating portion 205, and the first accommodating portion 204 is arranged between the second accommodating portion 205 and the first baffle 3. It can be understood that the upper end and the side end of the diaphragm 7 form an integrated structure with the main body of the above-mentioned approximately cylindrical structure, and the lower end of the diaphragm 7 is not connected to the first baffle 3, but forms a accommodating space, namely the first accommodating portion 204, between the diaphragm 7 and the first baffle 3, so that it can be used for the installation of the air guide 9, and at the same time facilitates the gas to flow from the first air guide portion 4 and the second air guide portion 5 of the first baffle 3 to the corresponding position (refer to the flow path of the gas). Figure 6 ).

[0044] Preferably, if Figure 4 and Figure 5As shown, in an embodiment, the second guide portion 5 includes at least two groups of guide hole groups, each group of guide hole groups includes a plurality of second guide holes 501, and at least two groups of guide hole groups are sequentially arranged from the second end of the chamber to the first end of the chamber, and the number of second guide holes 501 included in the guide hole group arranged from the second end of the chamber to the first end of the chamber gradually decreases. In an embodiment, the second guide portion 5 may include three groups of guide hole groups, the guide hole group near the second end of the chamber includes five second guide holes 501, the guide hole group near the first end of the chamber includes three second guide holes 501, and the guide hole group located between the two groups of guide hole groups includes four second guide holes 501. These three groups of guide hole groups arranged sequentially can make the gas dissipate in vortex in the chamber, and at the same time form a vortex at the opening position of the chamber for noise elimination.

[0045] Preferably, if Figure 4 As shown, in an embodiment, the plurality of chambers may include a plurality of flow guide chambers 801 and at least one exhaust chamber 802. Since in the above, the second silencing space 2 is divided into the first exhaust chamber 202 and the second exhaust chamber 203 by the second baffle 201, the first exhaust chamber 202 and the second exhaust chamber 203 may each include a plurality of flow guide chambers 801 and at least one exhaust chamber 802 to satisfy the separate flow of gas in the two exhaust chambers. Further, the plurality of flow guide chambers 801 are separated from each other by the partition 7 and formed into a flow guide portion, and at least one exhaust chamber 802 is arranged at the end of the flow guide portion, that is, the exhaust chamber 802 needs to be arranged at the end of the flow guide chamber 801 to facilitate exhaust. The exhaust hole 6 is arranged at the top of the exhaust chamber 802. The gas entering the plurality of flow guide chambers 801 through the first flow guide hole 401 and the second flow guide hole 501 flows along the gas flow direction and finally flows to the exhaust chamber 802, and is discharged through the exhaust hole 6 at the top of the exhaust chamber 802. In an embodiment, the exhaust chamber 802 of the first exhaust chamber 202 is arranged at Figure 4 The exhaust chamber 802 of the second exhaust chamber 203 is arranged at the upper part of Figure 4 The lower part of Figure 7 , the gas flows in a generally clockwise direction. Accordingly, if the exhaust cavity 802 of the first exhaust chamber 202 is arranged at Figure 4 The exhaust chamber 802 of the second exhaust chamber 203 is arranged at the lower part of Figure 4 In the upper part, the gas flows in a roughly counterclockwise direction.

[0046] Preferably, if Figure 4 As shown, in the embodiment, the spacer 7 can be formed into a rectangular plate-shaped structure, but it is not limited thereto. The spacer 7 can also be formed into an arc-shaped structure, for example, Figure 4 From the top view, the partition 7 is formed in an arc shape, which can also allow the gas to flow in the chamber and form a vortex at the opening to eliminate noise.

[0047] The use process of the muffler for the scroll compressor is as follows: Figure 6 and Figure 7 The scroll compressor silencer is installed on the fixed plate 10. When the scroll compressor moves, the gas flows out from the exhaust channel of the fixed plate 10, passes through the first silencer space 1, the first guide hole 401 and the second guide hole 501 of the first baffle 3, and enters the second silencer space 2. Figure 6 As shown, the gas entering the second silencing space 2 through the first guide hole 401 enters the chamber from the first end of the chamber, and the gas entering the second silencing space 2 through the second guide hole 501 enters the chamber from the second end of the chamber; Figure 7 As shown, after the gas enters the chamber, it moves along the flow path in the guide cavity 801, and finally is discharged from the exhaust cavity 802 through the exhaust hole 6 at the top. During the whole process, as the gas passes through multiple guide holes and multiple guide cavities 801, eddy current dissipation will be performed, and a vortex will be formed at the opening of the chamber for silencer, thereby reducing aerodynamic noise.

[0048] The muffler device for the scroll compressor can perform secondary muffler on the gas through the cooperation between the first muffler space and the second muffler space, and the specially designed second muffler space can effectively consume the energy of the gas, thereby reducing the aerodynamic noise. By using the muffler device, the aerodynamic noise of the scroll compressor can be significantly reduced, especially when running at high speed, the aerodynamic noise problem caused by gas pulsation can be solved, and it is suitable for scroll compressors with large displacement; because the muffler device will not change the original structure of the scroll compressor, it can greatly reduce the noise of the scroll compressor without reducing the energy efficiency of the scroll compressor, improve the sound quality of the scroll compressor, and thus enhance the product competitiveness of the scroll compressor.
