It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes have not been shown in detail to avoid obscuring the description of the present application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

As shown in fig. 1, the embodiment of the present application provides an air duct component 1, where the air duct component 1 includes a volute 10 and a flow guiding member 20, so as to reduce air duct noise and increase use comfort.

The volute 10 is shaped like a snail shell, having a body portion 11 and an outlet portion 12. In operation, air enters the body portion 11 of the volute 10, flows through the annular flow passage between the body portion 11 and the fan blades, and is discharged from the outlet portion 12. Here, the shape of the outlet portion 12 may be determined according to actual needs; illustratively, the outlet portion 12 may be a square hollow passage.

As shown in fig. 1 to 3, the deflector 20 is provided in the outlet 12, and can deflect air discharged from the outlet 12. Here, the side of the deflector 20 near the body portion 11 forms a serration 21. In other words, the serration part 21 is closest to the body part 11 than other regions on the deflector 20; accordingly, the air discharged from the outlet portion 12 will first contact the serration 21 when flowing toward the baffle 20. For example, the axial direction of the scroll casing 10 may be disposed in a horizontal direction, and the outlet portion 12 may be located above the body portion; accordingly, the deflector 20 may be positioned above the body portion 11 such that the serrations 21 are located at the bottom side region of the deflector 20, the serrations 21 correspondingly remaining opposite the body portion 11. The serration part 21 has a serration structure with a varying relief, forming a plurality of surfaces with different positions and orientations. Due to the sawtooth undulating structure of the sawtooth part 21, air is split into a plurality of smaller airflows when contacting the sawtooth part 21, and different ones of the plurality of smaller airflows are respectively contacted with different surfaces of the sawtooth part 21 through the shunting effect, so that on one hand, the airflow impact on the same surface of the sawtooth part 21 is reduced, and the larger noise caused by the concentrated impact of the airflows on a certain plane is avoided; on the other hand, noise sound waves generated by air flow impact are formed on different surfaces of the saw tooth part 21, so that the needed wave path difference and time difference are formed between the noise sound waves, superposition enhancement can be avoided when the noise sound waves interfere, mutual cancellation and weakening of the noise sound waves are ensured, and noise generated in the flow guiding process is reduced.

Here, the number of the air outlets 13 of the scroll casing 10 may be determined according to actual needs, which is not limited in the embodiment of the present application. In some embodiments, the volute 10 may have two air outlets 13 disposed opposite to each other, and the body portion 11, the outlet portion 12, and the two air outlets 13 are connected in sequence. The flow guiding member 20 may be disposed between the two air outlets 13, and guides the air discharged from the outlet 12 to the two air outlets 13, which has both flow dividing and guiding functions. In this way, the air duct component 1 can discharge air from different air outlets 13 and different sides of the air conditioner, and compared with the arrangement mode of a single air outlet 13 in the related art, the air duct component can reduce the air flow impact and the air speed of each air outlet 13, so that the air speed of each air outlet 13 is kept in a preferred range, and the air noise is reduced.

As shown in fig. 1-3, in some examples, the baffle 20 may have two baffle surfaces 22 disposed opposite one another. The two diversion surfaces 22 and the two air outlets 13 are oppositely arranged in a one-to-one correspondence, and the air sent out from the outlet part 12 is split into the two air outlets 13. Here, the two guide surfaces 22 are connected by the serration 21 near one end of the body 11. In other words, the serration 21 is located between the two guide surfaces 22 near one end edge of the body 11. Thus, when the air discharged from the outlet portion 12 is branched while flowing toward the deflector 20, the air will first contact the serration 21, so that the branching process mainly occurs in the region where the serration 21 is located. By utilizing the sawtooth fluctuation structure of the sawtooth part 21, on one hand, the airflow impact on the same surface on the sawtooth part 21 can be reduced, the larger noise caused by the airflow concentrated impact on a certain plane is avoided, on the other hand, the required wave path difference is formed between the noise sound waves, the superposition enhancement is avoided when the noise sound waves interfere, the mutual offset attenuation of the noise sound waves is ensured, and the noise generated in the air splitting process is reduced.

The specific structure of the serration 21 may be determined according to practical needs, and the embodiment of the present application is not limited thereto. In some examples, the serration part 21 may have a plurality of through grooves 211 sequentially disposed, and two ends of the through grooves 211 are respectively connected to two diversion surfaces 22. In this way, after the air discharged from the outlet portion 12 is split by contacting the saw tooth portion 21, the air can flow along the through grooves 211 to the two diversion surfaces 22, so that the saw tooth portion 21 has a better diversion and splitting effect.

The setting direction of the two air outlets 13 may be determined according to actual needs, which is not limited in the embodiment of the present application. For example, the two air outlets 13 may be disposed opposite to each other in a first direction, which is parallel to the axial direction of the scroll casing 10. Here, the axial direction of the scroll casing 10 is the center axial direction of the annular flow passage of the scroll casing 10. Accordingly, the through groove 211 may extend along the first direction, so that the extending direction of the through groove 211 and the setting direction of the two air outlets 13 are kept consistent, and the air after being split can accurately flow to the two air outlets 13 along the flow guiding surface 22.

As shown in fig. 1-4, for example, the outlet portion 12 may have oppositely disposed volute tongue sides 121 and opposite sides 122, the volute tongue sides 121 and opposite sides 122 being opposite side walls of the outlet portion 12; the volute tongue side 121 has a tongue-like structure like a tongue, and can prevent air from circulating in the volute 10. Due to the structural characteristics of the volute 10, when air is discharged from the body portion 11 to the outlet portion 12, the air is relatively intensively distributed on one side of the outlet portion 12 near the volute tongue side 121, and the air outlet speed and the air outlet flow amount of the side are large, so that large airflow impact is formed; on the side of the outlet 12 near the opposite side 122, the air distribution is relatively thin, so that the air outlet speed and the air outlet flow are smaller, and different areas of the outlet 12 show uneven air outlet speed and flow, and the air outlet uniformity is lower. Here, the plurality of through grooves 211 may be sequentially disposed in a direction approaching the opposite side 122 from the volute tongue side 121, so that both the air discharged from the volute tongue side 121 and the air discharged from the opposite side 122 can be noise-reduced and split by the serration 21 and can be directed by the through grooves 211.

The depth of each through groove 211 may be set according to actual needs, which is not limited in the embodiment of the present application. As shown in fig. 2 and 5, the depth of the through groove 211 may be configured to be progressively less in the direction from the volute tongue side 121 toward the opposite side 122, as an example. In other words, among the plurality of through grooves 211, the through groove 211 nearer to the volute tongue side 121 has a larger depth to form a deeper groove, and the through groove 211 nearer to the opposite side 122 has a smaller depth to form a shallower groove, in a directional gradient arrangement. As before, due to the structural characteristics of the volute 10, the volute tongue side 121 has a greater air-out speed and air-out flow, and the opposite side 122 has a lesser air-out speed and air-out flow. The depth of the through grooves 211 is gradually reduced as above, so that the through grooves 211 which are closer to the volute tongue side 121 are deeper and have larger surface area, the air containing capacity and the air dividing capacity of the through grooves 211 corresponding to the side are increased, the range of wave path difference when noise sound waves are generated in different areas of the surfaces of the through grooves 211 is increased, the noise sound waves generated when the air with larger flow rate and wind speed contacts the through grooves 211 can be counteracted by interference instead of strengthening by interference, and the noise reduction requirements under the conditions of larger wind speed and larger flow rate are met; the through grooves 211 corresponding to the opposite sides 122 are shallower and have smaller surface areas, so that the noise reduction capability of the through grooves 211 of the sides can be matched with smaller wind speed and flow conditions, and the air flow speed and flow rate of the sides are improved due to the more sensitive diversion and diversion speeds.

The length of each through groove 211 along the extending direction thereof may be set according to actual needs, which is not limited in the embodiment of the present application. As shown in fig. 7, in some embodiments, the length of the through slot 211 decreases in its direction of extension, in a direction approaching the opposite side 122 from the volute tongue side 121. In other words, among the plurality of through grooves 211, the through groove 211 nearer to the volute tongue side 121 has a longer length and forms a longer groove, and the through groove 211 nearer to the opposite side 122 has a shorter length and forms a shorter groove, in a directional gradient arrangement. As before, due to the structural characteristics of the volute 10, the volute tongue side 121 has a greater air-out speed and air-out flow, and the opposite side 122 has a lesser air-out speed and air-out flow. The depth of the through grooves 211 is gradually decreased as above, so that the through grooves 211 which are closer to the volute tongue side 121 are longer and have larger surface area, the containing capacity and the flow dividing capacity of the through grooves 211 corresponding to the side to air are increased, the range of wave path difference when noise sound waves are generated in different areas of the surfaces of the through grooves 211 is increased, the noise sound waves generated when the air with larger flow rate and wind speed contacts the through grooves 211 can be counteracted by interference instead of strengthening by interference, and the noise reduction requirements under the conditions of larger wind speed and larger flow rate are met; the through grooves 211 corresponding to the opposite sides 122 are shorter and have smaller surface areas, so that the noise reduction capability of the through grooves 211 of the sides can be matched with smaller wind speed and flow conditions, and the flow diversion speed is sensitive, so that the wind outlet speed and flow of the sides are improved.

The shape of the through groove 211 may be determined according to actual needs, and may be a triangular groove, a square groove, a trapezoid groove, an arc groove, or the like, which is not limited in the embodiment of the present application. The shape of the flow guiding surface 22 may be determined according to actual needs, and various planar or curved structures may be adopted, which is not limited in the embodiment of the present application. Illustratively, the diversion surface 22 may have a cambered surface configuration, which can reduce the impact of air when reaching the diversion surface 22 and noise caused by the impact, and has a better diversion effect to make the air flow smoother.

The volute tongue configuration of the volute tongue side 121 may be determined according to actual needs, and may be of a type such as flat tongue, short tongue, deep tongue, tip tongue, etc., which is not limited in this embodiment. Illustratively, the volute tongue side 121 has an inclined volute tongue configuration. The inclined volute tongue structure is a volute tongue structure with a certain inclination angle, and the inclination angle is an included angle between a connecting line of a large circular arc midpoint and a small circular arc midpoint of the volute tongue side 121 and a projection line of the connecting line, so that the distance between a small circle of the volute tongue and a wind blade is changed. When air is split on the volute tongue side 121, the inclined volute tongue structure is adopted, so that the time for the air in different areas to reach the corresponding positions on the volute tongue side 121 is different, the phenomenon that the air simultaneously impacts the volute tongue side 121 to generate larger noise and noise superposition enhancement is avoided, and noise generated in the splitting process is reduced.

In some embodiments, the flow guide 20 may have a first end and a second end disposed sequentially opposite each other in a direction from the volute tongue side 121 toward the opposite side 122, the second end being located at an end of the first end away from the volute tongue side 121, and a side of the flow guide 20 near the body portion 11 gradually approaching the body portion 11 from the first end to the second end. In this way, the air guiding piece 20 gradually inclines from the first end to the second end, so that the distance between the first end and the volute tongue side 121 can be increased, the air outlet of the volute tongue side 121 with larger air speed and flow rate has larger travel difference when contacting the air guiding piece 20, the phenomenon that the air discharged from different areas of the volute tongue side 121 simultaneously impacts the first end to generate larger noise and noise superposition enhancement is avoided, noise waves can be mutually offset and weakened, and noise generated in the air guiding process is reduced.

The structural form of the flow guiding member 20 may be determined according to practical needs, and may be of a type such as a solid structure or a hollow structure, which is not limited in the embodiment of the present application. In some examples, the baffle 20 may have a hollow structure. The shape of the flow guide 20 may be determined according to practical needs, and may take the shape of a prism, a terrace, a prism, or the like, which is not limited in the embodiment of the present application. As shown in fig. 5-7, in some examples, the baffle 20 has a triangular prism shape with adjacent sides of the triangular prism having an arcuate face configuration.

In some embodiments, the air duct component 1 may further include an air inlet box 30, the air inlet box 30 being in communication with the inlet portion of the volute 10. The air inlet box 30 may introduce air into the volute 10; for example, where the duct component 1 is a fresh air duct component, the air inlet box 30 may be in communication with the outdoor environment, introducing outdoor fresh air into the volute 10. In some embodiments, the air duct component 1 may further include a centrifugal fan blade 41 and a driving motor 42 that drives the centrifugal fan blade 41 to rotate, where the centrifugal fan blade 41 is disposed in the volute 10. Accordingly, the air duct component 1 is a centrifugal air duct component, having the corresponding characteristics of a centrifugal fan. The type of the driving motor 42 may be determined according to actual needs, and types such as a servo motor, a stepping motor, etc. may be used, which is not limited in the embodiment of the present application.

The structural form of the volute 10 may be determined according to practical needs, and may be a structural form such as an integral structure, a split structure, or the like, which is not limited in the embodiment of the present application. In some embodiments, the volute 10 may include a first volute component 10a and a second volute component 10b, the first volute component 10a and the second volute component 10b being oppositely connected to form the volute 10; the scroll casing 10 adopting the split structure is easy to manufacture, and the manufacturing difficulty and the production cost can be reduced. In some examples, two air outlets 13 of the volute 10 may be formed on the first volute member 10a and the second volute member 10b, respectively. For example, the volute tongue side 121 may have a split-splice structure formed by splicing portions formed on the first and second volute components 10a and 10b, respectively.

As shown in fig. 1 to 7, an embodiment of the present application provides an air conditioner including the air duct member 1 of any of the above embodiments. Here, the type of the air conditioner may be determined according to actual needs, and types such as a cabinet air conditioner, a hanging air conditioner, etc. may be adopted, which is not limited in the embodiment of the present application. The air conditioner provided by the embodiment of the application adopts the air duct component 1, so that on one hand, the air flow impact on the same surface on the sawtooth part 21 can be reduced, and the larger noise caused by the concentrated impact of the air flow on a certain plane is avoided; on the other hand, noise sound waves generated by air flow impact are formed on different surfaces of the saw tooth part 21, so that the needed wave path difference exists between the noise sound waves, superposition enhancement can be avoided when the noise sound waves interfere, mutual cancellation and weakening of the noise sound waves are ensured, and noise generated in the flow guiding process is reduced.
