[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention 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 this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0045] In the present invention, unless otherwise specified, the directional words used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

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

[0047] like Figures 1 to 12As shown, the air deflector assembly includes a bracket 10, a limiting structure 20, a rotating structure 30 and an air deflector 40. The limiting structure 20 is arranged on the bracket 10, and the limiting structure 20 includes a limiting body 21 and an elastic arm 22, and the elastic arm 22 is arranged on the outer surface of the limiting body 21. The rotating structure 30 includes 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 and the connecting portion 32 are locked to drive the connecting portion 32 to rotate synchronously. Among them, the inner surface of the mounting recess 311 includes a plurality of first recesses 312 arranged at intervals along a preset direction; when the air deflector 40 rotates to a preset position or rotates to a preset angle, at least a portion of the elastic arm 22 can selectively extend into at least one first recess 312 and limit with the first recess 312 to position the air deflector 40; the preset direction is consistent with the rotation direction of the rotating structure 30.

[0048] By applying the technical solution of this embodiment, when the user needs to adjust the air outlet direction of the range hood, the air guide plate 40 is controlled to drive the rotating structure 30 to rotate to a preset position or a preset angle. At this time, at least a portion of the elastic arm 22 can selectively extend into at least one first recess 312 and cooperate with the first recess 312 to position the air guide plate 40, and then fix the air guide plate 40 at this position through the limiting structure 20, effectively controlling the opening and closing angle of the air guide plate 40, solving the problem that the wind direction of the range hood cannot be effectively adjusted in the prior art and affects the user experience, thereby improving the user experience. At the same time, through the above-mentioned design of this embodiment, the air guide plate assembly can accurately control the rotation angle of the air guide plate 40, avoiding the problem of inaccurate wind direction adjustment caused by inaccurate position of the air guide plate 40, and improving the use effect of the range hood.

[0049] like Fig.10 As shown, the inner surface of the mounting recess 311 includes a plurality of first protrusions 313 spaced apart in a preset direction, at least one first protrusion 313 is disposed between each two adjacent first recesses 312, and at least one first recess 312 is disposed between each two adjacent first protrusions 313. In this way, the above arrangement makes the coordination between the elastic arm 22, the first protrusion 313 and the first recess 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 this embodiment, a first convex portion 313 is disposed between each two adjacent first concave portions 312, and a first concave portion 312 is disposed between each two adjacent first convex portions 313. Under high wind speed of the range hood, the above arrangement can effectively avoid displacement of the air guide plate 40 due to wind pressure changes, ensure consistency and stability of wind direction adjustment, thereby improving the efficiency of fume extraction and reducing 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 is limitedly matched with the first recess 312. When the air deflector 40 needs to be adjusted to the second angle position, the air deflector 40 is operated to drive the rotating structure 30 to rotate relative to the limiting structure 20, so that the elastic arm 22 continuously undergoes elastic deformation in the process of matching with the first protrusion 313 and the first recess 312, until the air deflector 40 rotates to the second angle position, at which time the elastic arm 22 extends into another first recess 312 and is limitedly matched with the first recess 312.

[0052] like Fig.10 As shown, the elastic arm 22 includes a bending arm body 221 and a second protrusion 222. The first end of the bending arm body 221 is connected to the rotating body 31. The second protrusion 222 is arranged on the second end of the bending arm body 221. Among them, the inner surface of the first recess 312 is a first arcuate surface, and the outer surface of the second protrusion 222 has a second arcuate surface. When the second protrusion 222 extends into the first recess 312 to cooperate with the first recess 312, the first arcuate surface fits with the second arcuate surface, and the outer surface of the first protrusion 313 has a third arcuate surface. In this way, the above-mentioned arrangement makes the elastic arm 22 and the first recess 312 cooperate more closely, improves the positioning accuracy of the air deflector, and at the same time, the design of the arcuate surface reduces the friction between the elastic arm 22 and the first recess 312, and prolongs the service life of the air deflector assembly.

[0053] In this embodiment, the above-mentioned structural setting of the elastic arm 22 ensures that the air guide plate 40 can be accurately fixed in the required position after each adjustment, avoiding usage problems caused by wear or inaccurate positioning, ensuring the long-term stable operation of the equipment, and reducing maintenance costs.

[0054] like Fig.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 to the outer peripheral surface of the circular ring structure. The second plate body 2212 is connected to the circular ring structure through the first plate body 2211, and the second plate body 2212 and the first plate body 2211 are arranged at an angle. The second convex portion 222 is arranged on an end of the second plate body 2212 away from the first plate body 2211. Among them, a section S is made at the connection between the first plate body 2211 and the circular ring structure, and the section S is arranged at an acute angle to the first plate body 2211. In this way, the above-mentioned arrangement not only ensures the elasticity of the elastic arm 22, but also enables it to extend and retract more smoothly when the air guide plate 40 rotates, thereby improving the response speed of the air guide plate assembly, facilitating timely adjustment of the wind direction, effectively coping with the sudden increase of oil smoke, and improving the resilience of the equipment. At the same time, the above arrangement makes the structure of the bending arm body 221 simpler, easier to process and realize, and reduces the processing cost and difficulty of the elastic arm 22.

[0055] In this embodiment, the connection portion 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] like Fig. 9 As shown, the air deflector assembly also includes a matching assembly, and the matching assembly includes a first matching portion 61 and a second matching portion 62, wherein the first matching portion 61 is arranged on the bracket 10. The second matching portion 62 is arranged on the limiting structure 20. Among them, one of the first matching portion 61 and the second matching portion 62 is a protrusion, and the other of the first matching portion 61 and the second matching portion 62 is a groove, and the protrusion extends into the groove and matches with the groove to connect the bracket 10 and the limiting structure 20. In this way, the above-mentioned setting of the matching assembly realizes the detachable connection between the limiting structure 20 and the bracket 10, and also improves the assembly stability of the two, which 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 structural selection of the first matching portion 61 and the second matching portion 62 more flexible to meet different usage requirements and working conditions, and improves the processing flexibility of the staff.

[0057] In this embodiment, the first matching portion 61 is a protrusion, and the second matching portion 62 is a groove. The protrusion extends into the groove and matches with the groove in a limiting manner to achieve assembly of the bracket 10 and the limiting structure 20 .

[0058] Optionally, there is one first matching portion 61 and one second matching portion 62; or, there are multiple first matching portions 61, and the multiple first matching portions 61 are arranged at intervals along a preset direction; there are multiple second matching portions 62, and the multiple second matching portions 62 are arranged one-to-one with the multiple first matching portions 61. In this way, the above arrangement makes the selection of the number of the first matching portions 61 and the second matching portions 62 more flexible, and the installation of the air guide assembly more flexible, and different matching methods can be selected according to different product requirements and space restrictions, thereby improving the adaptability of the product.

[0059] In this embodiment, there are four first matching parts 61 and four second matching parts 62, and the four second matching parts 62 are arranged in one-to-one correspondence with the four first matching parts 61. In this way, the above arrangement increases the connection strength between the bracket 10 and the limiting structure 20, thereby preventing the limiting structure 20 from falling off from the bracket 10 and affecting the structural stability of the air guide assembly.

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

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

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

[0063] In this embodiment, there are two elastic arms 22 , 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 arms 22 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the number of the elastic arms 22 is three, four, five, six, or more.

[0065] In this embodiment, the limiting body 21 is a circular ring structure, the plurality of second matching portions 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 mutual interference between the components, ensure the normal operation of the air guide plate assembly, and also improve the structural strength of the rotating body 31.

[0066] Optionally, the second convex portion 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 concave portion 312 and the first convex portion 313, thereby extending the service life of the air guide plate assembly. At the same time, the smooth shape design also improves the aesthetics of the product.

[0067] Optionally, the outer circumference of the rotating structure 30 is provided with anti-skid patterns; or, the outer circumference of the rotating structure 30 includes a plurality of third convex portions 33 and a plurality of second concave portions 34 arranged at intervals along a preset direction, at least one second concave portion 34 is arranged between each two adjacent third convex portions 33, and at least one third convex portion 33 is arranged between each two adjacent second concave portions 34. In this way, the above arrangement improves the comfort and accuracy of the user when operating the rotating structure 30, and the arrangement of the anti-skid patterns or the third convex portions 33 and the second concave portions 34 can effectively prevent the user's hand from slipping, thereby improving the user experience of the product.

[0068] like Fig. 9 , Fig.11 as well as Fig.12 As shown, the limiting structure 20 is located on one side of the bracket 10, and a buckle 70 is provided on the other side of the bracket 10. In this way, the above-mentioned arrangement of the buckle 70 makes the installation and removal of the air guide plate assembly more convenient, facilitates the maintenance and cleaning of the product, and improves the user-friendliness of the product.

[0069] like Fig.10 As shown, the connecting portion 32 has a mounting hole 321, one end of the air guide plate 40 is inserted into the mounting hole 321, the hole wall of the mounting hole 321 includes two anti-rotation surfaces 3211 arranged opposite to each other, and the air guide plate 40 includes a connecting plate, and the two plate surfaces of the connecting plate are arranged one-to-one with the two anti-rotation surfaces 3211, and each anti-rotation surface 3211 contacts its corresponding plate surface. In this way, the above arrangement ensures a stable connection between the air guide plate 40 and the connecting portion 32, avoids the air guide plate 40 from shaking due to external force during operation, and improves the use effect of the product.

[0070] In this embodiment, the two elastic arms 22 are fitted with the inner surface of the mounting recess 311 by interference fit. When the rotating structure 30 causes the elastic arms 22 to deform axially, the deformed elastic arms 22 simultaneously apply 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, so that the air guide plate 40 can stay at any angle. Compared with the traditional limiting structure in which the shaft hole is interfered with by friction to achieve the fixing of the air guide plate, the deformation of the elastic arms 22 is all caused by the deformation of the injection molding material itself, and will not fail due to material consumption caused by friction. At the same time, the hand feel is comfortable when turning.

[0071] like Fig. 9As shown, the bracket 10 includes 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, and the limiting surface 121 is used to limit the limiting structure 20 so that there is a preset gap between the bracket body 11 and the rotating structure 30. Among them, the first matching portion 61 is arranged on the boss 12. In this way, the above-mentioned setting makes the disassembly and assembly of the limiting structure 20 and the bracket 10 easier and simpler on the one hand, and reduces the difficulty of disassembly and assembly of the two; on the other hand, the above-mentioned setting of the preset gap ensures that the rotating structure 30 will not interfere with the bracket 10 in motion during the rotation process, thereby improving the operating reliability of the air guide assembly.

[0072] like Figures 1 to 4 As shown, the present application also provides a range hood, comprising a body 80, an air guide plate assembly and an air outlet grille 90, wherein the body 80 has an air outlet 50, the air guide plate assembly is mounted at the air outlet 50, and the air outlet grille 90 is arranged on the outside of the air guide plate assembly. The air guide plate assembly is the above-mentioned air guide plate assembly.

[0073] In this embodiment, the range hood further includes a fan module, which is disposed in the machine body 80 .

[0074] In this embodiment, the air guide plate assembly is matched with the body 80 through the buckle 70, one side of the air guide plate 40 is fixed in the fixing hole on the fan module, and the other side is installed on the mounting hole 321 of the rotating structure 30, and then the bracket 10 is pressed and installed corresponding to the reserved mounting position on the fan module until the three buckles 70 are installed in place, and the installation of the air guide plate assembly is completed. In this way, the above installation method effectively ensures the integrity of the fan appearance. During normal use, if there are foreign objects or stains in the wind wheel, the wind wheel can be cleaned by removing the bracket 10 and the air guide plate 40, without removing the entire fan module and disassembling it, which greatly improves the convenience of user use.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0076] The air guide plate assembly includes a bracket, a limiting structure, a rotating structure and an air guide plate. The limiting structure is arranged on the bracket. The limiting structure includes a limiting body and an elastic arm. The elastic arm is arranged on the outer surface of the limiting body. The rotating structure includes a rotating body and a connecting part arranged on the rotating body. The rotating body has a mounting recess. The air guide plate is arranged at the air outlet. The air guide plate and the connecting part are locked to drive the connecting part to rotate synchronously. Among them, the inner surface of the mounting recess includes a plurality of first recesses arranged at intervals along a preset direction. In this way, when the user needs to adjust the air outlet direction of the range hood, the air guide plate is controlled to drive the rotating structure to rotate to a preset position or a preset angle. At this time, at least part of the elastic arm can selectively extend into at least one first recess and limit with the first recess to position the air guide plate, and then the air guide plate is fixed at the position through the limiting structure, so as to effectively control the opening and closing angle of the air guide plate, solve the problem that the wind direction of the range hood cannot be effectively adjusted in the prior art and affects the user experience, and improve the user experience.
