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 are not set forth in detail in order 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, in a first aspect, an embodiment of the present application provides a volute structure 1, where the volute structure 1 includes a volute body 10 and a first diversion element 20, so that noise in an air duct can be reduced, and comfort in use can be increased.

The volute body 10 is shaped like a snail shell and has a body part 11 and an outlet part 12 which are connected with each other; the body 11 may be provided with a fan blade, and the air may be discharged from the outlet 12 after passing through an annular flow passage between the body 11 and the fan blade. The body portion 11 may be configured to accommodate the fan blade and define a volute flow channel 13 with the outlet diffuser 131 of the volute flow channel 13 connected to the outlet portion 12 in the air flow direction thereof; here, the volute flow passage 13 is the aforementioned annular flow passage. A volute tongue 14 is formed at the joint of the body part 11 and the outlet part 12; the volute tongue 14 has a tongue-like structure like a tongue, and prevents air from circulating in the volute.

The first guiding element 20 is disposed at the air outlet diffuser 131 of the volute flow channel 13, and is configured to guide the airflow from a position far away from the volute tongue into the outlet portion 12. Here, the first baffle 20 may be partially disposed at the outlet diffuser 131 of the volute flow channel 13, and a portion of the first baffle 20 located in the outlet diffuser 131 extends along an extending direction of the outlet diffuser 131; alternatively, the first flow guiding member 20 may be integrally disposed at the outlet diffuser 131 of the volute flow channel 13, and the first flow guiding member 20 integrally extends along the extending direction of the outlet diffuser 131.

Thus, the first flow guide part 20 can guide the air to be discharged to the outlet 12 in a flow dividing manner in the air outlet diffuser 131, so that most of the air can flow in the area on the side of the first flow guide part 20 far away from the fan blade and sequentially enter the outlet 12 from the position far away from the volute tongue 14, and the air supply requirement of large air volume is met; only a small part of air can flow in the area between the first flow guide part 20 and the fan blade and sequentially reaches the position of the volute tongue 14, so that most of the air in the air is shunted to the outlet part 12 under the flow guide effect of the volute tongue 14, a smaller amount of air enters the area between the fan blade and the volute tongue 14, the amount of air which reaches the position of the volute tongue 14 and is shunted at the position of the volute tongue 14 and the impact effect which the volute tongue 14 may be subjected to are reduced, and the noise of the air duct is reduced.

In some examples, the first flow guide 20 may extend from the outlet diffuser 131 into the upstream section 132 of the outlet diffuser 131, such that the first flow guide 20 is partially disposed in the outlet diffuser 131 to form the first flow guide 21 and partially disposed in the upstream section 132 to form the second flow guide 22. Here, the upstream section 132 and the outlet diffuser section 131 are connected in series in the air flow direction of the volute flow path 13. The second diversion part 22 can extend along a first direction, the first direction is parallel to a tangent plane of the upstream section 132 at the connection position of the upstream section 132 and the air outlet diffuser 131, so that the air split by the first diversion part 20 can enter the air outlet diffuser 131 along the tangential direction of the upstream section 132 at the connection position of the upstream section 132 and the air outlet diffuser 131, the flowing directions of the air before and after splitting cannot be changed remarkably, the splitting effect is smooth, and the disturbance noise during splitting can be reduced.

2-3, in some embodiments, the volute body 10 may have a forward sidewall 10a and an aft sidewall 10b disposed axially opposite thereof; the first baffle 20 may be disposed on at least one of the front and rear sidewalls with a gap between the first baffle 20 disposed on one of the front and rear sidewalls and the other of the front and rear sidewalls. Thus, the area on the side of the first flow guide member 20 far away from the fan blade and the area on the side of the first flow guide member 20 close to the fan blade are not completely isolated; along with the air flowing direction, under the centrifugal action of the fan blade, the air in the area of the first flow guide part 20 close to one side of the fan blade can continuously enter the area of the first flow guide part 20 far away from one side of the fan blade. Correspondingly, the air quantity entering the outlet part 12 from the area of the first flow guide part 20 far away from the fan blade is gradually increased, so that on one hand, the air supply requirement of large air quantity can be met, on the other hand, the air quantity reaching the volute tongue 14 and being shunted at the volute tongue 14 can be continuously reduced, and the impact possibly suffered by the volute tongue 14 and the air duct noise generated thereby are reduced.

In some examples, the orthographic projection of the first baffle 20 on the axial plane of the fan blade overlaps the fan blade portion. Therefore, the air sent out by the fan blade through centrifugal force can contact the first flow guide part 20, and the flow guide effect of the first flow guide part 20 is exerted. Here, the air volume on both sides of the first air guide member 20 may be controlled by adjusting the orthographic projection of the first air guide member 20 on the axial plane of the fan blade and the area of the overlapping area of the fan blade.

As shown in fig. 2, in some examples, the front sidewall 10a and the rear sidewall 10b are respectively provided with a first flow guide 20, and a gap is formed between the first flow guide 20 on the front sidewall 10a and the first flow guide 20 on the rear sidewall 10 b. Thus, the area of the first flow guide part 20 on the side far away from the fan blade is completely isolated from the area of the first flow guide part 20 on the side close to the fan blade; along with the air flowing direction, under the centrifugal action of the fan blade, the air in the area of the first flow guide part 20 close to one side of the fan blade can continuously enter the area of the first flow guide part 20 far away from one side of the fan blade. Correspondingly, the air quantity entering the outlet part 12 from the area of the first flow guide part 20 far away from the fan blade is gradually increased, so that on one hand, the air supply requirement of large air quantity can be met, on the other hand, the air quantity reaching the volute tongue 14 and being shunted at the volute tongue 14 can be continuously reduced, and the impact possibly suffered by the volute tongue 14 and the air duct noise generated thereby are reduced.

As shown in fig. 1, in some embodiments, the body portion 11 has a circumferential wall 111 surrounding the impeller; the outlet portion has a volute tongue side 121 and an opposite side 122 disposed opposite to each other such that volute tongue side 121 and opposite side 122 are opposite side walls of outlet portion 12. Here, the volute tongue side 121 and the volute tongue 14 are connected, and a portion of the circumferential wall 111 located at the outlet diffuser 131 may be connected to the opposite side 122.

In some examples, the distance between the portion of the circumferential wall 111 located at the outlet diffuser 131 and the first baffle 20 is a first distance, and the distance between the volute side 121 and the opposite side 122 is a second distance. Here, the first distance may be smaller than the second distance. Therefore, the area of the first flow guide part 20 on the side far away from the fan blade and the second flow guide part 30 can be kept staggered, so that air in the area can rapidly and accurately enter the outlet part 12 from the position far away from the volute tongue 14, and noise caused by impact on the volute tongue 14 is avoided; the area of the first flow guide part 20 close to the fan blade and the second flow guide part 30 can be kept opposite, so that the air in the area can quickly and accurately contact the second flow guide part 30, and the flow dividing effect of the second flow guide part 30 can be well exerted.

3-5, in some examples, the volute structure may further include a second baffle 30 disposed within the body portion 11 and/or the outlet portion 12; accordingly, the first baffle 20 may extend to an area adjacent to the second baffle 30. In some embodiments, the second baffle 30 may be disposed only within the body portion 11; in other embodiments, the second baffle 30 may be disposed only within the outlet portion 12; in still other embodiments, the second flow guide 30 may extend from within the body portion into the outlet portion 12 such that a portion of the second flow guide 30 is located within the body portion 11 and another portion is located within the outlet portion 12.

The structural shape of the second flow guiding element 30 can be determined according to actual needs, and the embodiment of the present application is not limited thereto. In some examples, the cross-section of the second baffle 30 may be linear as shown in fig. 6, V-shaped as shown in fig. 7, arcuate as shown in fig. 8, or triangular. Here, the cross section of the second baffle 30 is a section taken by a plane perpendicular to the axial direction of the volute body 10, and the axial direction of the volute body 10 may be the central axial direction of the annular flow passage of the volute body 10, that is, the axial direction of the fan blade. As shown in fig. 7, for example, the V-shaped peak portion may be located at an end close to the volute tongue 14, and the opening portion may be located at an end far from the volute casing 14. As shown in fig. 8, illustratively, the arcuate shaped dorsum may be held opposite the opposing side 122 and the bowstring may be held opposite the glans side 121.

In some examples, the second baffle 30 is disposed parallel to a sidewall of the outlet 12 that connects to the volute tongue 14, i.e., the volute tongue side 121. Here, the parallel arrangement may be absolutely parallel or substantially parallel. In the parallel arrangement mode, the second flow guide element 30 can form larger opposite flow at the position close to the volute tongue 14, so as to protect the volute tongue 14.

As shown in fig. 5, in some examples, one end of the second baffle 30 near the volute tongue 14 may be provided with a bent portion 31. The size of the bent portion 31 may be determined according to actual needs, and the embodiment of the present application is not limited thereto. For example, the bending radius of the bending part 31 may be smaller than that of the volute tongue 14. For example, the bending radius of the volute tongue 14 may be the peak radius of the volute tongue 14.

In other embodiments, as shown in fig. 9, the second baffle member 30 may be disposed within the body portion 11. A cavity 15 is formed between the second flow guide element 30 and the volute tongue 14, and the air pressure of one end of the cavity 15 far away from the outlet part 12 is lower than that of one end of the cavity 15 close to the outlet part 12 so as to form opposite air flow. The structural shape of the second flow guiding element 30 can be determined according to actual needs, and the embodiment of the present application is not limited thereto. In some examples, the cross-section of the second baffle 30 may be circular or elliptical. Here, the cross section of the second baffle 30 is a section taken by a plane perpendicular to the axial direction of the volute body 10, and the axial direction of the volute body 10 may be the central axial direction of the annular flow passage of the volute body 10, that is, the axial direction of the fan blade.

In some examples, in a direction from the outlet diffuser 131 toward the outlet portion 12, a portion of the circumferential wall 111 located at the outlet diffuser 131 is inclined toward a side of the tangential plane that is close to the fan blade. Thus, the air outlet diffuser 131 can be integrally inclined towards the volute tongue side 121, so that the air outlet effect and the noise reduction effect are better.

In some examples, the portion of the circumferential wall 111 located at the outlet diffuser 131 and the opposing side 122 are disposed coplanar. In this way, the side wall of the air outlet diffuser 131 far from the fan blade and the opposite side 122 of the outlet portion 12 are connected in a coplanar and smooth manner, so that the air in the air outlet diffuser 131 can smoothly flow into the outlet portion 12, the impact that the connection area of the air outlet diffuser 131 and the outlet portion 12 may be subjected to is reduced or eliminated, and the impact noise caused by the impact is reduced or eliminated.

The arrangement of the first flow guiding element 20 on the volute body 10 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some embodiments, the first baffle 20 may be integrally formed with the volute body 10. In other embodiments, the first baffle member 20 may be formed separately and then mounted to the volute body 10.

The arrangement of the second baffle 30 on the volute body 10 can be determined according to actual needs, and the embodiment of the present application does not limit this. In some examples, the second baffle 30 may be integrally formed with the volute body 10. In other examples, the second baffle member 30 may be separately formed and then mounted to the volute body 10.

The volute tongue structure of the volute tongue 14 can be determined according to actual needs, and can be of a type such as a flat tongue, a short tongue, a deep tongue, a pointed tongue, and the like, which is not limited in the embodiments of the present application. Illustratively, the volute tongue 14 has a sloped 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 the middle point of the large circular arc and the middle point of the small circular arc of the volute tongue 14 and a projection line of the connecting line, so that the distance between the small circle of the volute tongue and the fan blade is changed. When air is shunted at the volute tongue 14, the inclined volute tongue structure is adopted, so that the time for the air in different areas to reach corresponding positions on the volute tongue 14 is different, the air is prevented from impacting the volute tongue 14 at the same time to generate larger noise and noise superposition enhancement, and the noise generated in the shunting process is reduced.

The structural form of the volute body 10 may be determined according to actual needs, and may adopt structural forms such as an integral structure, a split structure, and the like, which is not limited in the embodiment of the present application. In some embodiments, the volute body 10 may include a first volute component 10 'and a second volute component 10 ", the first volute component 10' and the second volute component 10" being connected in opposition to form the volute body 10; the volute body 10 with the split structure is easy to manufacture, and the manufacturing difficulty and the production cost can be reduced. For example, the volute tongue 14 may have a split-type structure, which is formed by splicing portions formed on the first and second volute components 10' and 10 ″, respectively.

As shown in fig. 10, in some embodiments, the volute structure 1 may further include a flow guiding ring 16 disposed in the body portion 11, the flow guiding ring 16 includes an expanding section 161 disposed opposite the volute tongue 14, and a distance between the expanding section 161 and the volute tongue 14 is greater than a minimum distance between the flow guiding ring 16 and the circumferential wall 111. In this way, it is avoided that the minimum clearance area between the flow guide ring 16 and the circumferential wall 111 occurs near the volute tongue 14, so that a larger clearance between the expansion section 161 and the volute tongue 14 reduces the flow velocity and impact force in the area near the volute tongue 14, thereby reducing or eliminating larger noise due to larger impact. In some examples, the flow guiding ring 16 further includes an arc-shaped section 162, two ends of the expanding section 161 are respectively connected with the arc-shaped section 162 to form a complete annular ring body, the expanding section 161 is located inside a circle where the arc-shaped section 162 is located, for example, the expanding section 161 can be implemented in a chord mode of the circle where the arc-shaped section 162 is located, and the distance between the expanding section 161 and the volute tongue 14 is increased to reduce impact and impact noise.

As shown in fig. 1 to 11, in a second aspect, an embodiment of the present application provides an air duct component 100, where the air duct component 100 includes a volute structure 1 and a centrifugal blade 2 provided in any one of the above embodiments. The centrifugal fan blade 2 is arranged in the body part 11, and the body part 11 and the centrifugal fan blade 2 define a volute flow channel 13. The type of the air duct component 100 may be determined according to actual needs, and may be an indoor air duct component, a fresh air duct component, or the like, which is not limited in this embodiment of the application.

In some embodiments, the ducting part 100 may also include a hood 3. The air inlet cover 3 is communicated with the inlet part of the volute body 10. The air inlet cover 3 can introduce air into the volute body 10; for example, when the air duct 100 is a fresh air duct, the air inlet cover 3 can communicate with the outdoor environment to introduce fresh air into the volute body 10. In some embodiments, the air duct component 100 may further include a filter screen frame 4 for mounting a filter screen, and the filter screen frame 4 may be disposed between the air inlet cover 3 and the volute body 10; the filter screen can filter the air, improves the air quality.
