[0043] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0045] In the present application, unless otherwise stated, the orientation words such as "up, down" are generally directed to the direction shown in the drawings, or to the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left, right" is generally directed to the left and right shown in the drawings; "inner, outer" refers to the inner and outer relative to the contour of each component, but the above orientation words are not used to limit the present application.

[0046] In order to solve the problem that the air direction of the range hood in the prior art cannot be effectively adjusted, affecting the user experience, the present application provides an air deflector assembly and a range hood with the same.

[0047] As Figures 1 to 12As shown, the air deflector assembly comprises a support 10, a limiting structure 20, a rotating structure 30 and an air deflector 40. The limiting structure 20 is arranged on the support 10, and the limiting structure 20 comprises a limiting body 21 and an elastic arm 22 arranged on the outer surface of the limiting body 21. The rotating structure 30 comprises a rotating body 31 and a connecting portion 32 arranged on the rotating body 31, and the rotating body 31 has a mounting recess 311. The air deflector 40 is arranged at the air outlet 50, and the air deflector 40 is rotationally connected with the connecting portion 32 to drive the connecting portion 32 to rotate synchronously. The inner surface of the mounting recess 311 comprises a plurality of first recesses 312 arranged at intervals in a preset direction; when the air deflector 40 rotates to a preset position or rotates by a preset angle, at least part of the elastic arm 22 can selectively extend into at least one first recess 312 and limitally cooperate with the first recess 312 to position the air deflector 40; and the preset direction is consistent with the rotating direction of the rotating structure 30.

[0048] When the user needs to adjust the air outlet direction of the range hood, the air deflector 40 drives the rotating structure 30 to rotate to a preset position or rotate by a preset angle, at least part of the elastic arm 22 can selectively extend into at least one first recess 312 and limitally cooperate with the first recess 312 to position the air deflector 40, and then the air deflector 40 is fixed at the position by the limiting structure 20, so as to effectively control the opening angle of the air deflector 40, solve the problem that the air direction of the range hood cannot be effectively adjusted in the prior art, and improve the user experience. At the same time, through the above design of the embodiment, the air deflector assembly can accurately control the rotating angle of the air deflector 40, avoid the problem of inaccurate air direction adjustment caused by inaccurate position of the air deflector 40, and improve the use effect of the range hood.

[0049] As shown in the figure, Figure 10 The inner surface of the mounting recess 311 comprises a plurality of first convex portions 313 arranged at intervals in a preset direction, at least one first convex portion 313 is arranged between each adjacent two first recesses 312, and at least one first recess 312 is arranged between each adjacent two first convex portions 313. In this way, the above arrangement makes the cooperation between the elastic arm 22 and the first convex portions 313 and the first recesses 312 more stable when the air deflector 40 rotates, reduces the shaking of the air deflector 40 during operation, and improves the overall performance of the air deflector assembly.

[0050] In the embodiment, one first protrusion 313 is arranged between every two adjacent first recesses 312, and one first recess 312 is arranged between every two adjacent first protrusions 313. The above arrangement can effectively avoid the displacement of the air deflector 40 due to the change of wind pressure at high wind speed of the range hood, ensure the consistency and stability of the air direction adjustment, thereby improving the range hood efficiency and reducing the noise.

[0051] Specifically, the limiting structure 20 is fixed. When the air deflector 40 is at the first angle position, the elastic arm 22 extends into a first recess 312 and limits the cooperation with the first recess 312. When it is needed to adjust the air deflector 40 to the second angle position, the air deflector 40 drives the rotating structure 30 to rotate relative to the limiting structure 20, so that the elastic arm 22 continuously deforms elastically in the cooperation with the first protrusion 313 and the first recess 312, until the air deflector 40 is rotated to the second angle position, at this time, the elastic arm 22 extends into another first recess 312 and limits the cooperation with the first recess 312.

[0052] As shown in Figure 10 The elastic arm 22 includes a bent arm body 221 and a second protrusion 222. The first end of the bent arm body 221 is connected with the rotating body 31. The second protrusion 222 is arranged on the second end of the bent arm body 221. The inner surface of the first recess 312 is a first arc surface, the outer surface of the second protrusion 222 has a second arc surface, when the second protrusion 222 extends into the first recess 312 to limit the cooperation with the first recess 312, the first arc surface and the second arc surface are fitted, and the outer surface of the first protrusion 313 has a third arc surface. In this way, the above arrangement makes the cooperation between the elastic arm 22 and the first recess 312 more closely, improves the positioning accuracy of the air deflector, at the same time, the design of the arc surface reduces the friction between the elastic arm 22 and the first recess 312, prolongs the service life of the air deflector assembly.

[0053] In the embodiment, the above structure of the elastic arm 22 ensures that the air deflector 40 can be accurately fixed at the required position after each adjustment, avoids the use problems caused by wear or inaccurate positioning, ensures the long-term stable operation of the equipment, and reduces the maintenance cost.

[0054] As shown in Figure 10As shown, the limiting body 21 is a circular ring structure, and the bending arm body 221 includes a first plate body 2211 and a second plate body 2212. The first plate body 2211 is connected with the outer circumferential surface of the circular ring structure. The second plate body 2212 is connected with the circular ring structure through the first plate body 2211, and the second plate body 2212 is arranged at an included angle with the first plate body 2211. The second protrusion 222 is arranged on one end of the second plate body 2212 away from the first plate body 2211. Among them, a tangent plane S is made through the connecting part of the first plate body 2211 and the circular ring structure, and the tangent plane S is arranged at an acute angle with the first plate body 2211. In this way, the above-mentioned setting not only ensures the elasticity of the elastic arm 22, but also enables it to stretch and contract more smoothly when the air deflector 40 rotates, improves the response speed of the air deflector assembly, facilitates timely adjustment of the wind direction, effectively deals with sudden increase of oil fume, and improves the adaptability of the equipment. At the same time, the above-mentioned setting makes the structure of the bending arm body 221 more simple, easy to process and realize, and reduces the processing cost and difficulty of the elastic arm 22.

[0055] In the present embodiment, the connecting part 32 extends to both sides of the rotating body 31 and extends into the limiting body 21, so that the internal structure of the air deflector assembly is more compact, and the overall occupied space of the air deflector assembly is reduced.

[0056] As shown in the figure, Figure 9 The air deflector assembly further comprises a matching assembly, the matching assembly comprising a first matching part 61 and a second matching part 62, the first matching part 61 being arranged on the support 10. The second matching part 62 is arranged on the limiting structure 20. Among them, one of the first matching part 61 and the second matching part 62 is a protrusion, and the other of the first matching part 61 and the second matching part 62 is a groove, the protrusion extending into the groove and being limitedly matched with the groove to connect the support 10 and the limiting structure 20. In this way, the above-mentioned setting of the matching assembly realizes the detachable connection of the limiting structure 20 and the support 10, also improves the assembly stability of the two, not only simplifies the installation process of the air deflector assembly, improves the assembly efficiency, but also reduces the production cost. At the same time, the above-mentioned setting makes the structure selection of the first matching part 61 and the second matching part 62 more flexible to meet different use requirements and working conditions, and improves the processing flexibility of the workers.

[0057] In the present embodiment, the first matching part 61 is a protrusion, and the second matching part 62 is a groove, the protrusion extending into the groove and being limitedly matched with the groove to realize the assembly of the support 10 and the limiting structure 20.

[0058] Optionally, the first matching part 61 is one, and the second matching part 62 is one; or the first matching part 61 is multiple, and the multiple first matching parts 61 are arranged at intervals along a preset direction; the second matching part 62 is multiple, and the multiple second matching parts 62 are arranged one by one corresponding to the multiple first matching parts 61. In this way, the above arrangement makes the number of the first matching part 61 and the second matching part 62 more flexible to choose, and the installation of the air deflector assembly more flexible, which can choose different matching modes according to different product requirements and space limitations, and improves the adaptability of the product.

[0059] In the embodiment, the first matching part 61 is four, the second matching part 62 is four, and the four second matching parts 62 are arranged one by one corresponding to the four first matching parts 61. In this way, the above arrangement increases the connection strength between the support 10 and the limiting structure 20, thereby preventing the limiting structure 20 from being separated from the support 10 and affecting the structural stability of the air deflector assembly.

[0060] It should be noted that the number of the first matching part 61 is not limited to this and can be adjusted according to the working conditions and use requirements. Optionally, the first matching part 61 is two, or three, or five, or six, or multiple.

[0061] It should be noted that the number of the second matching part 62 is not limited to this and can be adjusted according to the working conditions and use requirements. Optionally, the second matching part 62 is two, or three, or five, or six, or multiple.

[0062] Optionally, the elastic arm 22 is one; or the elastic arm 22 is multiple, and the multiple elastic arms 22 are arranged at intervals along a preset direction. In this way, the above arrangement makes the number of the elastic arm 22 more flexible to choose to meet different use requirements and working conditions, and also improves the processing flexibility of the workers. At the same time, the design of a single elastic arm 22 simplifies the structure and reduces the cost, and the setting of multiple elastic arms 22 can improve the positioning accuracy and stability of the air deflector assembly.

[0063] In the embodiment, the elastic arm 22 is two, and the two elastic arms 22 are arranged at intervals along a preset direction.

[0064] It should be noted that the number of the elastic arm 22 is not limited to this and can be adjusted according to the working conditions and use requirements. Optionally, the elastic arm 22 is three, or four, or five, or six, or multiple.

[0065] In the embodiment, the limiting body 21 is a circular ring structure, the multiple second matching parts 62 are arranged on the inner side of the limiting body 21, and the elastic arm 22 is arranged on the outer side of the limiting body 21. In this way, the above staggered arrangement can make full use of the limited space, avoid the mutual interference between the components, ensure the normal work of the air deflector assembly, and also improve the structural strength of the rotating body 31.

[0066] Optionally, the second protrusion 222 is a cylinder or a sphere. In this way, the above-mentioned arrangement of the cylinder or the sphere can reduce the friction between the first protrusion 312 and the first protrusion 313, prolonging the service life of the air deflector assembly. At the same time, the smooth appearance design also improves the aesthetics of the product.

[0067] Optionally, the outer circumferential surface of the rotating structure 30 is provided with anti-skid lines; or the outer circumferential surface of the rotating structure 30 comprises a plurality of third protrusions 33 and a plurality of second recesses 34 arranged at intervals in a predetermined direction, at least one second recess 34 is arranged between each adjacent two third protrusions 33, and at least one third protrusion 33 is arranged between each adjacent two second recesses 34. In this way, the above-mentioned arrangement improves the comfort and accuracy of the user when operating the rotating structure 30, and the anti-skid lines or the third protrusions 33 and the second recesses 34 can effectively prevent the user from slipping, improving the user experience of the product.

[0068] As shown in Figure 9 , Figure 11 and Figure 12 , the limiting structure 20 is located on one side of the support 10, and the buckle 70 is arranged on the other side of the support 10. In this way, the above-mentioned arrangement of the buckle 70 makes the installation and disassembly of the air deflector assembly more convenient, facilitating the maintenance and cleaning of the product, and improving the user-friendliness of the product.

[0069] As shown in Figure 10 , the connecting portion 32 has a mounting hole 321, one end of the air deflector 40 is inserted into the mounting hole 321, and the hole wall of the mounting hole 321 comprises two opposite stop surfaces 3211, the air deflector 40 comprises a connecting plate, two plate surfaces of the connecting plate are arranged one by one corresponding to the two stop surfaces 3211, and each stop surface 3211 is in contact with the plate surface corresponding thereto. In this way, the above-mentioned arrangement ensures the stable connection between the air deflector 40 and the connecting portion 32, avoids the shaking of the air deflector 40 during work due to external force, and improves the use effect of the product.

[0070] In the present embodiment, the two elastic arms 22 are interference-fitted with the inner surface of the mounting recess 311, and when the rotating structure 30 axially deforms the elastic arm 22, the deformed elastic arm 22 simultaneously applies an axial force to the rotating structure 30. Due to the existence of this axial force, the rotating structure 30 can rotate 360° to be positioned at any position, and thus the air deflector 40 can stay at any angle. Compared with the traditional limiting structure which realizes the fixation of the air deflector by interference of the shaft hole and friction, the deformation of the elastic arm 22 is caused by the deformation of the injection material itself, and will not fail due to material consumption caused by friction, and the feeling of the user when operating is comfortable.

[0071] As shown in Figure 9As shown, the bracket 10 comprises a bracket body 11 and a boss 12. The boss 12 is arranged on the bracket body 11, and the boss 12 has a limiting surface 121 for limiting cooperation with the limiting structure 20 to have a preset gap between the bracket body 11 and the rotating structure 30. The first cooperation part 61 is arranged on the boss 12. In this way, the above-mentioned arrangement on the one hand makes the disassembly of the limiting structure 20 and the bracket 10 more easy and convenient, and reduces the disassembly difficulty of the two; on the other hand, the above-mentioned arrangement of the preset gap ensures that the rotating structure 30 does not interfere with the movement of the bracket 10 in the rotating process, thereby improving the operation reliability of the deflector assembly.

[0072] As shown, Figures 1 to 4 It is provided that an extractor hood, comprising a body 80, a deflector assembly and an air outlet grille 90, the body 80 has an air outlet 50, the deflector assembly is installed at the air outlet 50, and the air outlet grille 90 is arranged outside the deflector assembly. The deflector assembly is the deflector assembly described above.

[0073] In this embodiment, the extractor hood further comprises a fan module, and the fan module is arranged in the body 80.

[0074] In this embodiment, the deflector assembly and the body 80 are matched by the buckles 70, one side of the deflector 40 is fixed in the fixing hole on the fan module, the other side is installed on the mounting hole 321 of the rotating structure 30, then the bracket 10 is pressed and installed at the reserved installation position on the fan module, until the three buckles 70 are installed in place, that is, the installation of the deflector assembly can be completed. In this way, the above-mentioned installation method effectively ensures the integrity of the fan appearance, and when in use, if there are foreign matters or stains in the fan wheel, the fan wheel can be cleaned by disassembling the bracket 10 and the deflector 40, without the need to disassemble the entire fan module, thereby greatly improving the convenience of use of the user.
