As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 6, the present invention provides a silencer assembly 100 for an air conditioner, wherein the silencer assembly 100 for an air conditioner is applied to an air conditioning system for reducing noise generated when the air conditioning system is in operation.

Specifically, the silencer assembly 100 for the air conditioner comprises a cylinder 10, an inlet pipe 20 and a plurality of vortex-shaped distributed drainage sheets 211, wherein an inner cavity 11 is formed in the cylinder 10, one end of the inlet pipe 20 is inserted into the cylinder 10 and is communicated with the inner cavity 11, and the other end of the inlet pipe 20 is positioned outside the cylinder 10 and is connected with an external pipeline; the side wall of one end of the inlet pipe 20 in the inner cavity 11 is provided with a plurality of communication holes 21 which are respectively communicated with the inside of the inlet pipe 20, each drainage sheet 211 corresponds to one communication hole 21, and the drainage sheet 211 is arranged on the inlet pipe 20 and can partially shield the corresponding communication hole 21, so that the flow area of the communication hole 21 is gradually changed from the inside to the outside of the inlet pipe 20.

It should be noted that, because the existing silencer is affected by the air conditioner assembly space and the installation size, only materials with smaller outer diameter and shorter size can be adopted for processing, so that the ideal noise output is often difficult to achieve, and a damping block needs to be additionally added outside a pipeline to achieve the purposes of reducing noise and vibration, which is time-consuming and labor-consuming. In the application, the flow guide sheet 211 is arranged on the inlet pipe 20, so that the airflow (gas-liquid mixed refrigerant) is guided and decomposed into multiple strands of soft airflow (gas-liquid mixed refrigerant) through the flow guide sheet 211, the noise and vibration generated by high-speed airflow are reduced, and meanwhile, the multiple strands of airflow contact and impact with the inner wall of the barrel 10, so that the turbulent state of gas formation can be effectively promoted, collision and noise reduction are performed, and the noise reduction effect is improved.

Alternatively, stainless steel or red copper is used as the material of the cylinder 10 and the inlet tube 20.

Further, the cylinder 10 includes a body 12 and a cone cover 13 disposed at one end of the body 12, the inlet pipe 20 extends from the cone cover 13 into the inner cavity 11, and the communication hole 21 extends into the cone cover 13 along the axial direction of the inlet pipe 20, so that the communication hole 21 is partially or completely located in the cone cover 13.

It can be understood that the cross-sectional area of the cone cover 13 is increased from small to large along the direction of the air flow in the inlet pipe 20, that is, when the air flow comes out from the communication hole 21 through the inlet pipe 20, the air flow hits the inner wall of the cone cover 13 via a shorter distance, so that the air flow collides with the inner wall of the cone cover 13 at a faster speed to be silenced, and the silencing speed is effectively increased.

Alternatively, the cone cover 13 may be welded or integrally formed with the body 12, and the inlet tube 20 may be connected to the cylinder 10 by welding or the like.

Example one

Referring to fig. 1 to 2, the drainage piece 211 is formed by punching a side wall of the inlet tube 20, and the drainage piece 211 is partially detached from the inlet tube 20 and is recessed and separated toward the inside of the inlet tube 20, so that a communication hole 21 is formed on the side wall of the inlet tube 20; when the air current enters from the inlet pipe 20 and passes through the communication hole 21, the air current is blocked and guided by the concave flow guiding sheet 211 in the inlet pipe 20, the air current which moves linearly becomes a spiral shape and is ejected from the communication hole 21 of the inlet pipe 20, and the vortex-shaped air current is formed and collides with the inner wall of the cylinder 10. Because the streamline of the fluid is influenced by the structure of the diversion sheet 211, the flow area, the direction and the speed of the fluid are changed, the area is increased, the speed is reduced, and the expansion ratio is increased, so that the noise in most frequency bands can be eliminated or reduced, and the noise elimination effect is improved.

Specifically, in this embodiment, the drainage pieces 211 are circular arc curvature connection structures, and the concave direction thereof is clockwise or counterclockwise, so that the drainage pieces 211 form a vortex shape.

Preferably, the communicating hole 21 is a strip-shaped hole, the drainage piece 211 is rectangular, and the strip-shaped communicating hole 21 can widen the noise elimination frequency band of the silencer, and especially in the case of low-frequency noise, the silencing effect of the silencer is most remarkable.

Specifically, the communication holes 21 in the shape of strip holes are oriented in the axial direction of the inlet pipe 20, and the plurality of communication holes 21 in the shape of strip holes are uniformly distributed in the circumferential direction of the inlet pipe 20, so that the communication holes 21 are not easily clogged, and the reliability of the silencer assembly 100 for an air conditioner can be improved to ensure that the silencer can continue silencing.

Preferably, in the present embodiment, the number of the opened communication holes 21 is 3 to 6, that is, the number of the opened communication holes 21 may be 3, 4, or 5. It can be understood that if the number of the communicating holes 21 is too small, the flow rate of the air flow is too small, and the silencing effect is greatly reduced; if the number of the communicating holes 21 is too large and the pipe wall area of the inlet pipe 20 is limited, the strength of the inlet pipe 20 is greatly reduced and the processing difficulty is increased; of course, in other embodiments, the number of the communication holes 21 may be 6, 7, 8 or more according to the actual use environment.

Preferably, as shown in fig. 3, along the circumferential direction of the inlet pipe 20, an included angle θ between a tangent of the communicating hole 21 at a side away from the flow guiding sheet 211 and a tangent of the flow guiding sheet 211 at a side away from the inlet pipe 20 is in a range of 25 ° to 35 °, that is, the included angle θ may be 25 °, 30 ° or 35 °, the opening angle of the flow guiding sheet 211, whether being too large or too small, may not achieve a good silencing effect, and the opening angle of the flow guiding sheet 211 may only enable the air flow to achieve a good collision effect when contacting the flow guiding sheet 211 when being in a range of 25 ° to 35 °, so as to improve silencing performance.

Further, as shown in fig. 2, a through hole 22 is opened on an end surface of one end of the inlet tube 20 inserted into the inner cavity 11, and the through hole 22 is communicated with the inside of the inlet tube 20; it can be understood that the opening of the through hole 22 is equivalent to the opening of the communication hole 21 and is additionally provided with an airflow circulation channel, so that the airflow flows out of the through hole 22 and collides with other airflows in the inner cavity 11, thereby enhancing the silencing effect.

Preferably, in the present embodiment, the diameter of the through hole 22 is 2mm to 4mm, i.e., the diameter of the through hole 22 may be 2mm, 3mm, or 4 mm. It should be noted that if the diameter of the through hole 22 is too large, the sound absorption function is not achieved; if the diameter of the through-hole 22 is too small, the frequency of noise may even increase. Of course, in other embodiments, the diameter of the through hole 22 may also be selected from other values, and is not limited herein.

Example two

As shown in fig. 4 and fig. 5, the structure of the second embodiment is substantially the same as the structure of the first embodiment, and the same parts can be referred to the description of the first embodiment, which is not repeated herein, but the difference is that:

in the present embodiment, the communication holes 21 have a plurality of sets, the plurality of sets of communication holes 21 are distributed in the axial direction of the inlet pipe 20, each set of communication holes 21 includes a plurality of communication holes 21, and the plurality of communication holes 21 in each set are uniformly distributed in the circumferential direction of the inlet pipe 20.

EXAMPLE III

As shown in fig. 6 and 7, the structure of the third embodiment is substantially the same as that of the first embodiment, and the same parts can be referred to the explanations of the first embodiment, which are not repeated herein, but the differences are as follows:

in the present embodiment, the drainage piece 211 is formed by punching the side wall of the inlet tube 20, and the drainage piece 211 is partially detached from the inlet tube 20 and protrudes and is separated toward the outside of the inlet tube 20 so that the communication hole 21 is formed on the side wall of the inlet tube 20.

Referring to the first to third embodiments, as shown in fig. 8 to 9, optionally, one corner or at least one side of the drainage sheet 211 is concave or convex and separated from the inlet pipe 20 to form a communication hole 21.

It can be understood that, since the flow guide sheet 211 has a rectangular shape, the flow guide sheet 211 has four corners, when only one corner of the flow guide sheet 211 is separated from the inlet pipe 20 (fig. 7), the airflow forms a vortex shape in the small cavity of the flow guide sheet 211, the resistance of the airflow becomes large, and the airflow collides with a plurality of positions of the inner wall of the cylinder 10 and then flows out of the cylinder 10, thereby enhancing the noise reduction effect; when the drainage piece 211 is separated from the inlet tube 20 at least two corners (fig. 8), it is easier to process and the complexity of the process is reduced.

Alternatively, the portion of the drainage sheet 211 that is recessed inside the inlet tube 20 or protrudes outside the inlet tube 20 may have a flat plate shape or an arc shape.

The utility model also provides an air conditioning system (not shown), including idle call muffler subassembly 100.

This air conditioning system also has the advantages of the air conditioning silencer assembly 100 described above.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
