A muffler assembly and an air conditioning system according to an embodiment of the present invention will be described with reference to fig. 1 to 7.
Fig. 1 is a perspective view of a muffler assembly according to an embodiment of the present invention, and fig. 2 is a front view of the muffler assembly according to an embodiment of the present invention. This amortization subassembly includes casing 1 and a plurality of amortization piece 2, 2 interval arrangements of a plurality of amortization pieces, and the outer fringe of amortization piece 2 links to each other with the medial surface of casing 1 is fixed, and amortization piece 2 is equipped with ventilation hole 21, and ventilation hole 21 of a plurality of amortization pieces 2 is linked together and forms the amortization wind channel with casing 1, and this amortization wind channel has air intake 22 and air outlet 23.
Because the silencing air channel is formed by the shell 1 and the silencing blocks 2 which are arranged at intervals, the silencing channel becomes a variable cross-section channel, and a sudden change cross-section channel is formed between every two adjacent silencing blocks 2, so that the air flow can be effectively silenced when passing through the silencing channel. The silencing assembly provided by the embodiment of the invention can be used as a part to be assembled with an air duct of an air conditioner, so that air flow in the air duct can be silenced through the silencing assembly, the structure is simple, the manufacturing is convenient, and the air duct structure of the air conditioner is simplified.
Further, as shown in fig. 3, which is a schematic structural diagram of a sound-deadening block in an embodiment of the present invention, in the sound-deadening assembly provided in the embodiment of the present invention, the vent hole 21 of the sound-deadening block 2 is a variable cross-section hole, and the cross section of the vent hole is gradually reduced along the airflow direction, so that the sound-deadening air duct has a gradually changing cross section in the vent hole 21. Through the combination of the gradual change section and the abrupt change section between the adjacent silencing blocks 2, a silencing air duct with the gradual change section and the abrupt change section which are alternately changed is formed, so that the noise reduction and silencing effect of the silencing assembly is further improved.
On the basis of the above embodiment, the housing 1 includes the first side wall 11, the second side wall 12, and the arc-shaped wall 13, both ends of the arc-shaped wall 13 parallel to the arrangement plane of the plurality of sound-deadening blocks 2 connect the first side wall 11 and the second side wall 12, and the cross-sectional shape of the arc-shaped wall 13 parallel to the arrangement plane of the plurality of sound-deadening blocks 2 is an arc shape. When the noise reduction assembly is installed in an air conditioning duct, the arrangement plane of the plurality of noise reduction blocks 2 is generally parallel to the longitudinal axial plane of the duct. The outer edge of the sound-deadening block 2 is fixedly connected with the inner sides of the first side wall 11, the second side wall 12 and the arc-shaped wall 13, respectively. After entering the silencing passage, the airflow can be deflected in the direction blocked by the arc-shaped wall 13. Therefore, the silencing assembly provided by the embodiment of the invention can be arranged at the wind direction conversion position of the air conditioner air duct, and simultaneously realizes the conversion and silencing of the wind direction. In addition, compared with the traditional plane type baffle, the arc-shaped wall 13 can play a certain noise reduction role. Further, as shown in fig. 1 and 2, a plurality of sound-deadening blocks 2 are arranged in a circular array.
In order to further improve the sound deadening effect of the sound deadening channel, as shown in fig. 1 and 5, the sectional shape of the arc-shaped wall 13 perpendicular to the arrangement direction of the plurality of sound deadening blocks 2 is an arc shape. When the first side wall 11 and the second side wall 12 are parallel planar plates, for example, the arc-shaped wall 13 is a spherical plate; for another example, the arc-shaped wall 13 has a circular arc-shaped cross section perpendicular to the direction in which the plurality of sound-deadening blocks 2 are arranged.
On the basis of the above-mentioned embodiment, the housing 1 is fixed with the rotating shaft 15, and the rotating shaft 15 is used for connecting the rotary driving member. Specifically, the rotation shafts 15 are fixed to the housing 1 on both sides of the plane in which the plurality of sound-deadening blocks 2 are arranged, and for example, the two rotation shafts 15 are fixed to the first side wall 11 and the second side wall 12, respectively. The rotating shafts 15 are used for being rotatably connected with the side walls of the air duct, the driving end of the rotary driving member is fixedly connected with one of the rotating shafts 15, and the rotating shaft 15 is driven to rotate by the rotary driving member 34, so that the housing 1 is driven to rotate. The rotation shaft 15 may be perpendicular to the arrangement plane of the plurality of sound-deadening blocks 2 to rotate the housing 1 on the arrangement plane. The silencing assembly provided by the embodiment of the invention can be arranged at the wind direction switching position of the air-conditioning air duct and is matched with the air inlet and the air outlet of the air duct, and the wind direction in the air duct can be switched by rotating around the rotating shaft 15.
Wherein, first lateral wall 11 and second lateral wall 12 are the plane board that is parallel to each other and perpendicular to pivot to make the amortization subassembly install in the rectangle wind channel through pivot 15, and when rotatory on the axis of ordinates in rectangle wind channel, first lateral wall 11 and second lateral wall 12 can be laminated with the inner wall in air conditioner wind channel mutually, are favorable to casing 1 to improve the leakproofness between the air conditioner wind channel inner wall.
Further, the cross-sectional shape of the arc-shaped wall 13 parallel to the arrangement plane of the plurality of sound-deadening blocks 2 is a circular arc having a center on the central axis of the rotating shaft 15. The arrangement enables the motion trail of each point of the outer side surface of the shell 1 on the section parallel to the arrangement plane of the plurality of silencing blocks 2 to be on the same circle in the rotation process of the silencing assembly. Install the amortization subassembly that this embodiment provided in the wind channel, can make it at rotatory in-process, the wind channel inner wall is unchangeable apart from the nearest position of casing 1, is favorable to simplifying the structure of the sealing member between amortization subassembly and the wind channel inner wall.
In the embodiment of the present invention, as shown in fig. 1 and fig. 2, circular arc-shaped guide rails 16 are respectively disposed on the outer sides of the first side wall 11 and the second side wall 12, and the centers of the guide rails 16 are located on the central axis of the rotating shaft 15. The surfaces of the air duct, which are attached to the first side wall 11 and the second side wall 12, are respectively and correspondingly provided with a guide structure matched with the guide rail 16. For example, the guide rail 16 is a circular arc-shaped protrusion protruding from the first side wall 11 and the second side wall 12, and the guide structure on the air inlet channel 3 is a guide groove conformal with the circular arc-shaped protrusion. During installation, the arc-shaped convex ribs are embedded into the guide grooves, so that the reliability of connection between the silencing component and the air inlet channel 3 is improved.
The embodiment of the invention also provides an air conditioning system, which comprises the silencing component in any embodiment, wherein the silencing component can be arranged at a position in an air duct where the wind direction needs to be converted, such as a corner of the air duct; or the two air ports are rotatably arranged in an air duct with three air ports, so that the two air ports are communicated with the other air port in a switching way.
Taking the silencing component as an example for explanation, fig. 4 is a schematic view of an assembly structure of the silencing component and the air duct according to an embodiment of the present invention, fig. 5 is a right side view of the assembly structure of the silencing component and the air duct in fig. 4, the silencing component is installed in an air inlet channel 3 of the air conditioner, the air inlet channel 3 is configured with a first air opening 31, a second air opening 32 and a third air opening 33, and the air inlet channel 3 is installed with a rotary driving member 34 for driving the silencing component to rotate so as to switch the first air opening 31, the second air opening 32 and the third air opening 33 to communicate with each other. Specifically, the silencing assembly has two states in the air inlet channel 3 when the first air opening 31 is communicated with the third air opening 33 and the second air opening 32 is communicated with the third air opening 33. Wherein, the outer wall of the air inlet channel 3 is arranged at the third air port 33 and is provided with a fan, and the air inlet of the fan is communicated with the third air port 33. The fan may be a centrifugal fan, a cross-flow fan, or an axial-flow fan, and the embodiment of the present invention is not particularly limited. It should be noted that the noise reduction assembly may also be disposed in an air outlet duct of the air conditioner, that is, the third air opening 33 is an air inlet, and the first air opening 31 and the second air opening 32 are both air outlets, so as to switch the wind direction of the outlet air and reduce noise.
In one embodiment, the first tuyere 31 is coaxially disposed with the second tuyere 32, and the central axis of the first tuyere 31 is perpendicular to the central axis of the third tuyere 33. The rotation center of the noise reduction assembly is located on the central axis of the third tuyere 33. As shown in fig. 4, it can be ensured that the left and right relative positions of the air outlet 23 of the silencing air duct and the third air opening 33 are not changed when the silencing assembly is in the above two states, and it is ensured that the air flows through the silencing assembly in the same state under the condition that the air flows from the first air opening 31 to the third air opening 33 are the same as the air flows from the second air opening 32 to the third air opening 33, so that the two directions achieve the same silencing effect.
In one embodiment, fig. 6 is a schematic view illustrating an assembly structure of a silencing component and an air duct according to another embodiment of the present invention. The rotation center (such as the center of the rotating shaft 15) of the silencing component is positioned at the right outer side of the space above the third air opening 33, when the second air opening 32 is communicated with the third air opening 33, the air outlet 23 of the silencing air duct is correspondingly communicated with the third air opening 33, and the air flow completely passes through the silencing component; and when the silencing assembly rotates to the first tuyere 31 to communicate with the third tuyere 33, the gas flow directly flows to the third tuyere 33 without passing through the silencing assembly. Therefore, noise reduction and silencing are only carried out on the air flow from the second air opening 32 to the third air opening 33. Similarly, noise reduction and silencing can be realized only for the air flow in the direction from the first air opening 31 to the third air opening 33, which is not described again.
When the wind direction switching of the air conditioner air duct is realized by utilizing the silencing assembly, the vent holes are variable-section holes, and the cross sections of the vent holes in the airflow direction are gradually reduced, the silencing assembly is only utilized to carry out silencing and noise reduction on the inlet air in one direction. For example, the first air inlet 31 is connected to the outdoor fresh air channel, and the second air inlet 32 is connected to the indoor return air channel, so that the indoor return air is generally only subjected to noise reduction. At this time, the rotation center of the silencer assembly is set to the right outside of the space above the third tuyere 33, as shown in fig. 6 and 7, so that when the silencer assembly rotates to the state where the first tuyere 31 is communicated with the third tuyere 33, the outdoor fresh air does not directly flow to the third tuyere 33 through the silencer assembly, but only the indoor return air is silenced. In this case, the cross section of the ventilation hole 21 of the sound-deadening block 2 can be made to gradually decrease from the side away from the third tuyere 33 to the side close to the third tuyere 33.
On the basis of this embodiment, as shown in fig. 7, which is a schematic view illustrating an assembly structure of a noise reduction assembly and an air duct according to still another embodiment of the present invention, the first air opening 31 and the third air opening 33 may be coaxially disposed, and a central axis of the first air opening 31 is perpendicular to a central axis of the second air opening 32. When the cross section of the side of the vent hole 21 far away from the air outlet 23 to the side near the air outlet 23 is gradually reduced, the installation of the noise reduction component has directionality, which is suitable for reducing noise and eliminating noise of airflow in one direction. For example, the first air inlet 31 is connected to the outdoor fresh air channel, and the second air inlet 32 is connected to the indoor return air channel, so that the indoor return air is generally reduced in noise, and the outdoor fresh air directly flows to the third air inlet 33 without passing through the noise reduction assembly. At this time, the cross section of the vent hole 21 of the sound-deadening block 2 may be made to gradually decrease from the side distant from the third tuyere 33 to the side close to the third tuyere 33.
According to the air conditioning system provided by the embodiment of the invention, through rotating the silencing component in the air duct, the air direction switching of the air duct is realized, and meanwhile, the silencing of the first air opening 31 to the third air opening and/or the second air opening 32 to the third air opening can also be realized.
If the inner wall of the air inlet channel 3 and the outer side surface of the casing 1 cannot form a sealing fit, the first air port 31 and the second air port 32 cannot be completely blocked. For example, as shown in fig. 5, the air supply passage 3 is a rectangular duct, and the cross-sectional shape of the outer side surface in the arrangement direction of the sound-deadening blocks 2 is an arc shape, so that a gap exists between the sound-deadening assembly and the air supply passage 3 in both the above-described states. Therefore, on the basis of any of the above embodiments, when the housing 1 cannot be directly matched with the inner side wall of the air inlet channel 3 to form a sealing fit, a sealing member needs to be arranged in the air inlet channel 3, so that the first air opening 31 and the second air opening 32 can be completely blocked when the noise reduction assembly is in the above two states.
In the embodiment of the invention, a sealing plate is fixed in the air inlet pipeline in a direction vertical to the axis of the air inlet pipeline, and the outer side surface of the shell 1 can be tangent to the sealing plate to form the separation of the first air port 31 or the second air port 32 and the third air port 33. The shape and size of the sealing plate are matched with the gap between the shell 1 and the inner wall of the air inlet channel 3.
Specifically, as shown in fig. 4, the air inlet channel 3 is fixed with a first sealing plate 35 and a second sealing plate 36, and when the silencing assembly rotates to a state that the first tuyere 31 is communicated with the third tuyere 33, the housing 1 is matched with the first sealing plate 35 to block the second tuyere 32 from the third tuyere 33; when the silencing assembly rotates to a state that the second tuyere 32 is communicated with the third tuyere 33, the housing 1 is matched with the second sealing plate 36 to block the first tuyere 31 and the third tuyere 33. Wherein, the first sealing plate 35 and the second sealing plate 36 are required to be integrally matched with the arc-shaped wall 13, the first side wall 11 and the second side wall 12 to form the obstruction of the first tuyere 31 and the second tuyere 32 in the two states of the noise reduction assembly.
When the cross section of the casing 1 parallel to the arrangement plane of the plurality of silencing blocks 2 is arc-shaped, and the center of the arc is located on the central axis of the rotating shaft 15, the first air port 31 and the second air port 32 of the silencing assembly in the two states can be ensured to be in the blocking state only by arranging a sealing plate at the position where the air inlet channel 3 is closest to the casing 1. Specifically, as shown in fig. 6, a third sealing plate 37 is fixed in the air inlet channel 3, and the housing 1 can cooperate with the third sealing plate 37 to form a barrier between the first tuyere 31 or the second tuyere 32 and the third tuyere 33. Of course, two sealing plates may be provided, and the two sealing plates are respectively located at two sides of the position where the air intake passage 3 is closest to the noise reduction assembly.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
