[0001] This application relates to the field of air conditioner technology, specifically to an air duct component and an air conditioner. Background Technology

[0002] An air conditioner, also known as an air conditioning unit, regulates and controls parameters such as temperature, humidity, and airflow in an indoor environment to increase indoor comfort. However, air conditioners often experience significant duct noise, which reduces user comfort. Summary of the Invention

[0003] This application provides a duct component and an air conditioner that can reduce duct noise and increase user comfort.

[0004] On one hand, this application provides an air duct component, including: a volute having a body portion and an outlet portion; and a guide member disposed within the outlet portion, wherein a serrated portion is formed on the side of the guide member near the body portion.

[0005] In some embodiments, the volute has two air outlets arranged opposite each other, the body, the outlet and the two air outlets are connected in sequence, and the guide is disposed between the two air outlets.

[0006] In some embodiments, the air guide has two air guide surfaces arranged opposite to each other, the two air guide surfaces and the two air outlets are arranged opposite each other in a one-to-one correspondence, and the two air guide surfaces are connected at one end near the main body through the serrated portion.

[0007] In some embodiments, the serrated portion has a plurality of through grooves arranged in sequence, and the two ends of the through grooves are respectively connected to the two guide surfaces.

[0008] In some embodiments, the two air outlets are arranged opposite each other along a first direction, the first direction being parallel to the axial direction of the volute, and the through groove extending along the first direction.

[0009] In some embodiments, the outlet portion has a volute tongue side and an opposite side disposed opposite to each other, and the plurality of through slots are arranged sequentially along a direction from the volute tongue side toward the opposite side.

[0010] In some embodiments, the depth of the through groove decreases along the direction from the volute tongue side toward the opposite side.

[0011] In some embodiments, the length of the through groove decreases along its extension direction in a direction from the volute tongue side to the opposite side.

[0012] In some embodiments, the outlet portion has a volute tongue side and an opposite side disposed opposite to each other, the volute tongue side having an inclined volute tongue structure.

[0013] In some embodiments, the outlet portion has a volute tongue side and an opposite side disposed opposite to each other, and the guide has a first end and a second end disposed opposite to each other in a direction from the volute tongue side to the opposite side, the second end being located at the end of the first end away from the volute tongue side, and the side of the guide near the body portion gradually approaches the body portion from the first end to the second end.

[0014] In some embodiments, the volute includes a first volute component and a second volute component, which are connected relative to each other to form the volute.

[0015] On the other hand, embodiments of this application provide an air conditioner that includes the air duct component described in any of the above embodiments.

[0016] This embodiment of the application sets up a volute and a guide member, forming a serrated section on the side of the guide member close to the main body. When the main body of the volute delivers air outward through the outlet, the airflow first contacts the serrated section of the guide member. The undulating serrated structure of the serrated section can divide the air in contact with it into multiple smaller airflows. Through the diversion effect, different of the multiple smaller airflows contact different surfaces of the serrated section. On the one hand, this reduces the airflow impact on the same surface of the serrated section, avoiding the large noise caused by the concentrated impact of airflow on a certain plane. On the other hand, the noise waves generated by the airflow impact are formed on different surfaces of the serrated section, so that these noise waves have the required path difference. This can avoid the superposition and enhancement of noise wave interference, ensuring that the noise waves cancel each other out and weaken, thereby reducing the noise generated during the guiding process.

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0032] like Figure 1 As shown, this application provides a duct component 1, which includes a volute 10 and a guide 20, which can reduce duct noise and increase user comfort.

[0033] The volute 10 resembles a snail shell and has a body portion 11 and an outlet portion 12. During operation, air enters the body portion 11 of the volute 10, flows through the annular flow channel between the body portion 11 and the fan blade, and is discharged from the outlet portion 12. Here, the shape of the outlet portion 12 can be determined according to actual needs; for example, the outlet portion 12 can be a square hollow channel.

[0034] like Figures 1-3As shown, the guide member 20 is disposed within the outlet portion 12 to guide the air discharged from the outlet portion 12. Here, a serrated portion 21 is formed on the side of the guide member 20 closest to the body portion 11. In other words, the serrated portion 21 is closest to the body portion 11 compared to other areas on the guide member 20; correspondingly, the air discharged from the outlet portion 12 will first contact the serrated portion 21 when flowing through the guide member 20. For example, the axial direction of the volute 10 can be arranged in the horizontal direction, and the outlet portion 12 can be located above the body portion; correspondingly, the guide member 20 can be located above the body portion 11, such that the serrated portion 21 is located in the bottom area of ​​the guide member 20, and the serrated portion 21 is correspondingly opposite to the body portion 11. The serrated portion 21 has an undulating serrated structure, forming multiple surfaces with different positions and orientations. Due to the serrated undulating structure of the serrated part 21, the air is divided into multiple smaller airflows when it comes into contact with the serrated part 21. Through the diversion effect, different of the smaller airflows contact different surfaces of the serrated part 21. On the one hand, this reduces the airflow impact on the same surface of the serrated part 21 and avoids the large noise caused by the concentrated impact of airflow on a certain plane. On the other hand, the noise sound waves generated by the airflow impact are formed on different surfaces of the serrated part 21, so that these noise sound waves have the required path difference and time difference. This can avoid the superposition and enhancement of noise sound waves when they interfere, and ensure that the noise sound waves cancel each other out and weaken each other, thereby reducing the noise generated during the flow guidance process.

[0035] Here, the number of air outlets 13 of the volute 10 can be determined according to actual needs, and this embodiment does not limit this. In some embodiments, the volute 10 may have two air outlets 13 arranged opposite to each other, with the main body 11, the outlet 12, and the two air outlets 13 connected in sequence. The guide member 20 may be disposed between the two air outlets 13 to guide the air discharged from the outlet 12 to the two air outlets 13 respectively, serving both the function of diverting and guiding airflow. In this way, the air duct component 1 can discharge air from different air outlets 13 and different sides of the air conditioner. Compared with the single air outlet 13 arrangement in related technologies, the airflow impact and wind speed of each air outlet 13 can be reduced, keeping the wind speed of each air outlet 13 within an optimal range and reducing wind noise.

[0036] like Figures 1-3As shown, in some examples, the guide member 20 may have two guide surfaces 22 arranged opposite to each other. The two guide surfaces 22 and the two air outlets 13 are arranged opposite each other in a one-to-one correspondence, diverting the gas delivered from the outlet 12 to the two air outlets 13. Here, the ends of the two guide surfaces 22 near the body 11 are connected by a serrated portion 21. In other words, the serrated portion 21 is located between the edges of the ends of the two guide surfaces 22 near the body 11. In this way, when the air discharged from the outlet 12 is diverted as it flows through the guide member 20, the air will first come into contact with the serrated portion 21, so that the diversion process mainly occurs in the area where the serrated portion 21 is located. By utilizing the serrated undulating structure of the serrated portion 21, on the one hand, the airflow impact on the same surface of the serrated portion 21 can be reduced, and the large noise caused by the concentrated impact of airflow on a certain plane can be avoided. On the other hand, the required path difference between these noise sound waves can be ensured, so as to avoid the superposition and enhancement of noise sound wave interference, and ensure that the noise sound waves cancel each other out and weaken, thereby reducing the noise generated by the air during the diversion process.

[0037] The specific structure of the serrated section 21 can be determined according to actual needs, and this application embodiment does not limit it. In some examples, the serrated section 21 may have a plurality of through grooves 211 arranged in sequence, with two guide surfaces 22 connected to each end of the through grooves 211. In this way, the air discharged from the outlet section 12, after being diverted upon contact with the serrated section 21, can flow along the through grooves 211 to the two guide surfaces 22, giving the serrated section 21 a better guiding and diverting effect.

[0038] The orientation of the two air outlets 13 can be determined according to actual needs, and this embodiment does not limit this. For example, the two air outlets 13 can be arranged opposite each other along a first direction, which is parallel to the axial direction of the volute 10. Here, the axial direction of the volute 10 is the central axial direction of the annular flow channel of the volute 10. Correspondingly, the through groove 211 can extend along the first direction, so that the extension direction of the through groove 211 is consistent with the orientation of the two air outlets 13, allowing the diverted air to flow accurately along the guide surface 22 to the two air outlets 13.

[0039] like Figures 1-4As shown, exemplarily, the outlet 12 may have a volute tongue side 121 and a opposite side 122 disposed opposite to each other, the volute tongue side 121 and the opposite side 122 being opposite sidewalls of the outlet 12; the volute tongue side 121 has a tongue-shaped structure, which can prevent air from circulating within the volute 10. Due to the structural characteristics of the volute 10, when air is discharged from the body 11 to the outlet 12, the air is relatively concentrated on the side of the outlet 12 near the volute tongue side 121, where the air velocity and airflow are higher, resulting in a larger airflow impact; while on the side of the outlet 12 near the opposite side 122, the air distribution is relatively sparse, resulting in a lower air velocity and airflow, causing uneven airflow velocity and flow in different areas of the outlet 12, and low airflow uniformity. Here, multiple through slots 211 can be arranged sequentially along the direction from the volute tongue side 121 to the opposite side 122, so that the air discharged from the volute tongue side 121 and the air discharged from the opposite side 122 can be noise-reduced and diverted by the serrated part 21, and can be directed by the through slots 211.

[0040] The depth of each through slot 211 can be set according to actual needs, and this embodiment does not limit this. For example... Figure 2 and Figure 5 As shown, exemplarily, the depth of the through groove 211 can be configured to decrease gradually along the direction from the volute tongue side 121 towards the opposite side 122. In other words, among the multiple through grooves 211, the through grooves 211 closer to the volute tongue side 121 have a greater depth, forming deeper grooves, while the through grooves 211 closer to the opposite side 122 have a smaller depth, forming shallower grooves, exhibiting a directional gradual change relationship. As previously stated, due to the structural characteristics of the volute housing 10, the air outlet velocity and air outlet flow rate are greater on the volute tongue side 121, and smaller on the opposite side 122. By adopting the above-described decreasing depth setting for the through slots 211, the through slots 211 closer to the volute tongue side 121 are deeper and have a larger surface area, increasing the air-carrying capacity and diversion capacity of the through slots 211 on that side. This also increases the path difference range when noise waves are generated in different areas of the surface of these through slots 211, ensuring that the noise waves generated when air with high flow rate and wind speed come into contact with these through slots 211 can be interfered and canceled rather than interfered and reinforced, thus meeting the noise reduction requirements under conditions of high wind speed and high flow rate. On the other hand, the through slots 211 on the opposite side 122 are shallower and have a smaller surface area, which allows the noise reduction capacity of the through slots 211 on that side to match the conditions of lower wind speed and flow rate, and has a more sensitive guiding and diversion speed, thereby improving the outlet air speed and flow rate on that side.

[0041] The length of each through slot 211 along its extension direction can be set according to actual needs, and this embodiment does not limit this. For example... Figure 7As shown, in some embodiments, the length of the through groove 211 decreases along its extension direction from the volute tongue side 121 towards the opposite side 122. In other words, among the multiple through grooves 211, the through groove 211 closer to the volute tongue side 121 is longer and forms a longer groove, while the through groove 211 closer to the opposite side 122 is shorter and forms a shorter groove, exhibiting a directional gradual change relationship. As previously stated, due to the structural characteristics of the volute housing 10, the air outlet velocity and air outlet flow rate are higher on the volute tongue side 121 and lower on the opposite side 122. By adopting the above-described decreasing depth setting for the through slots 211, the through slots 211 closer to the volute tongue side 121 are longer and have a larger surface area, increasing the air-carrying capacity and diversion capacity of the through slots 211 on that side. This also increases the path difference range when noise waves are generated in different areas of the surface of these through slots 211, ensuring that the noise waves generated when air with high flow rate and wind speed come into contact with these through slots 211 can be canceled out rather than reinforced by interference, thus meeting the noise reduction requirements under conditions of high wind speed and high flow rate. On the other hand, the through slots 211 on the opposite side 122 are shorter and have a smaller surface area, which allows the noise reduction capacity of the through slots 211 on that side to match the conditions of lower wind speed and flow rate, and has a more sensitive guiding and diversion speed, thereby improving the outlet air speed and flow rate on that side.

[0042] The shape of the through groove 211 can be determined according to actual needs, and can be triangular, square, trapezoidal, arc-shaped, etc., and this application embodiment does not limit this. The shape of the guide surface 22 can be determined according to actual needs, and can be various planar or curved surface structures, and this application embodiment does not limit this. For example, the guide surface 22 can have an arc surface structure, which can reduce the impact of air when it reaches the guide surface 22 and the noise caused by the impact, and has a better guiding effect, making the air flow smoother.

[0043] The structure of the volute tongue side 121 can be determined according to actual needs, and can be of types such as flat tongue, short tongue, deep tongue, and pointed tongue. This application embodiment does not limit this. For example, the volute tongue side 121 has an inclined volute tongue structure. The inclined volute tongue structure is a volute tongue structure with a certain angle, which is the angle between the line connecting the midpoint of the large arc and the midpoint of the small arc of the volute tongue side 121 and the projection line of that line, thus changing the distance between the small arc of the volute tongue and the fan blade. When air is split on the volute tongue side 121, the inclined volute tongue structure allows air from different regions to reach corresponding positions on the volute tongue side 121 at different times, avoiding simultaneous air impact on the volute tongue side 121 and thus preventing excessive noise and noise superposition, reducing the noise generated during the splitting process.

[0044] In some embodiments, the guide member 20 may have a first end and a second end arranged sequentially opposite to each other along a direction from the volute tongue side 121 to the opposite side 122, with the second end located at the end of the first end away from the volute tongue side 121. The side of the guide member 20 closest to the body portion 11 gradually approaches the body portion 11 from the first end to the second end. In this way, the guide member 20 gradually tilts from the first end to the second end, which can increase the distance between the first end and the volute tongue side 121. This allows the air outlet of the volute tongue side 121, which has a higher wind speed and flow rate, to have a larger travel difference when it contacts the guide member 20. This avoids the simultaneous impact of air discharged from different areas of the volute tongue side 121 on the first end, which would generate greater noise and noise superposition. Instead, the noise waves can cancel each other out and reduce the noise generated during the guide process.

[0045] The structural form of the flow guide 20 can be determined according to actual needs, and can be of types such as solid or hollow structures; this application embodiment does not limit this. In some examples, the flow guide 20 can have a hollow structure. The shape of the flow guide 20 can be determined according to actual needs, and can be of shapes such as frustums or prisms; this application embodiment does not limit this. Figures 5-7 As shown, in some examples, the guide 20 has a triangular prism shape, and the two adjacent sides of the triangular prism have an arcuate surface structure.

[0046] In some embodiments, the duct component 1 may further include an air inlet box 30, which is connected to the inlet of the volute 10. The air inlet box 30 can introduce air into the volute 10; for example, when the duct component 1 is a fresh air duct component, the air inlet box 30 can be connected to the outdoor environment and introduce outdoor fresh air into the volute 10. In some embodiments, the duct component 1 may further include a centrifugal fan blade 41 and a drive motor 42 for driving the centrifugal fan blade 41 to rotate, the centrifugal fan blade 41 being disposed inside the volute 10. Accordingly, the duct component 1 is a centrifugal duct component and has the corresponding characteristics of a centrifugal fan. The type of drive motor 42 can be determined according to actual needs, and can be such as a servo motor, stepper motor, etc., which is not limited in this embodiment.

[0047] The structural form of the volute 10 can be determined according to actual needs, and can adopt structural forms such as an integral structure or a split structure. This application embodiment does not limit this. In some embodiments, the volute 10 may include a first volute component 10a and a second volute component 10b, which are connected relative to each other to form the volute 10. A split-structure volute 10 is easier to manufacture, reducing manufacturing difficulty and production costs. In some examples, the two air outlets 13 of the volute 10 can be formed on the first volute component 10a and the second volute component 10b, respectively. Exemplarily, the volute tongue side 121 can have a split splicing structure, formed by splicing together portions formed on the first volute component 10a and the second volute component 10b, respectively.

[0048] like Figures 1-7 As shown, this application embodiment provides an air conditioner, including the air duct component 1 of any of the above embodiments. Here, the type of air conditioner can be determined according to actual needs, and can be such as a cabinet air conditioner, a wall-mounted air conditioner, etc., and this application embodiment does not limit this. The air conditioner provided in this application embodiment uses the above-mentioned air duct component 1, which on the one hand can reduce the airflow impact on the same surface on the serrated part 21, and avoid the large noise caused by the concentrated impact of airflow on a certain plane; on the other hand, the noise sound waves generated by the airflow impact are formed on different surfaces of the serrated part 21, so that these noise sound waves have the required path difference, which can avoid the superposition and enhancement of noise sound wave interference, and ensure that the noise sound waves cancel each other out and weaken, thereby reducing the noise generated in the air guiding process.

[0049] The duct components and air conditioners provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
