The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0034] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0035] See also Figure 6 The embodiment of the utility model provides an air inlet ring of a range hood. The air inlet ring 10 is arranged on the side wall of the air cabinet 20 of the range hood to provide a smooth air inlet duct 13 for the range hood.

[0036] See also Figures 1 to 6 The air inlet ring 10 of the utility model embodiment includes a guide portion 11, a connecting portion 12, a first baffle 14 and a second baffle 15. The guide portion 11 is annular and forms an air inlet duct 13. The connecting portion 12 is connected to the outer circumference of the guide portion 11 and is used to connect to the wind cabinet 20. The connecting portion 12 may have a connecting hole 16 so that the connecting portion 12 can be connected to the wind cabinet 20 by screws.

[0037] The first baffle 14 is connected to the connecting portion 12, and a first guide groove 18 is formed between the first baffle 14 and the connecting portion 12 on the air inlet side. The first baffle 14 can block the liquid flowing along the outer surface of the air inlet ring 10 and collect it in the first guide groove 18. The liquid collected in the first guide groove 18 continues to flow along the first guide groove 18 under the action of gravity, so as to prevent the liquid such as sewage generated by cleaning the range hood from directly flowing onto the wind cabinet 20 along the direction of gravity.

[0038] The second baffle 15 is connected to the connecting portion 12, and the second baffle 15 and the first baffle 14 are located on the same side, and a second guide groove 19 is formed between the second baffle 15 and the connecting portion 12. The first baffle 14 can block the liquid flowing along the outer surface of the air inlet ring 10, and collect it in the first guide groove 18. The liquid collected in the first guide groove 18 continues to flow along the first guide groove 18 under the action of gravity, so as to prevent liquid such as sewage from directly flowing onto the wind cabinet 20 along the direction of gravity.

[0039] The second baffle 15 is arranged at a relative interval with the first baffle 14, and a confluence port 17 is formed between the first baffle 14 and the second baffle 15. The confluence port 17 is arranged at the lower end of the first baffle 14 and the second baffle 15. The liquid in the first guide groove 18 and the second guide groove 19 is collected at the confluence port 17, and can be uniformly collected through the confluence port 17 to avoid large-scale pollution of the wind cabinet 20, thereby improving user experience.

[0040] In some embodiments, the first baffle 14 and the connecting portion 12 may be an integral structure. The second baffle 15 and the connecting portion 12 may also be an integral structure. The air inlet ring 10 may be an integral structure as a whole. In a specific implementation, the air inlet ring 10 may be directly formed by a stamping or injection molding process, which effectively saves materials and labor. For example, the air guide portion 11, the connecting portion 12, and the first guide groove 18 and the second guide groove 19 may be integrally formed by a stamping process.

[0041] Of course, the first baffle 14 and the connecting portion 12 may also be connected by welding or other methods. The second baffle 15 and the connecting portion 12 may also be connected by welding or other methods.

[0042] In some embodiments, see Figure 2 The connecting portion 12 has a first extension portion 121 along the first direction, and the first extension portion 121 is bent toward the air inlet side to form a first baffle 14; the connecting portion 12 has a second extension portion 122 along the second direction, and the second extension portion 122 is bent toward the air inlet side to form a second baffle 15. The connecting portion 12 has extension portions in the first direction and the second direction respectively, which can facilitate the integral molding of the air inlet ring 10 by stamping. It saves labor and avoids the consumption of materials due to partial overlap required by other connection methods.

[0043] The first direction and the second direction are radial directions respectively, and are located on both sides of the gravity direction respectively, and the angles between the first direction and the second direction and the gravity direction are acute angles respectively.

[0044] In some embodiments, see Figure 3 and Figure 4, the angle between the first baffle 14 and the connection portion 12 and the angle between the second baffle 15 and the connection portion 12 are acute angles, respectively. The first baffle 14 and the second baffle 15 respectively effectively block the liquid flowing toward the outer surface of the air inlet ring 10, and make the liquid converge to the confluence port 17. In an exemplary embodiment, the angle between the first baffle 14 and the connection portion 12 can be 45° to 75°. The angle between the second baffle 15 and the connection portion 12 can be 45° to 75°. For ease of explanation, the angle between the first baffle 14 and the connection portion 12 is the first angle a, and the angle between the second baffle 15 and the connection portion 12 is the second angle b. The specific values ​​of the first angle a and the second angle b can be the same or different. The value of the first angle a is between 45° and 75°, which can make the first baffle 14 block the liquid flowing down to the maximum extent, and make the liquid converge to the confluence port 17 along the first guide groove 18. The value of the second angle b is between 45° and 75°, so that the second baffle 15 can block the flowing liquid to the maximum extent and make the liquid converge to the confluence port 17 along the second guide groove 19. In a specific implementation, the values ​​of the first angle a and the second angle b can be 50°, 55°, 60°, 65°, 70°, etc.

[0045] In some embodiments, the intersection line of the first baffle 14 and the connecting portion 12 may be an arc, so that the first guide groove 18 extends along the arc. The first guide groove 18 extends along the arc, and the slopes of the first guide groove 18 are different at different locations. When the liquid flows along the first guide groove 18 to the confluence port 17, as the slope of the first guide groove 18 gradually decreases, the flow rate of the liquid gradually decreases, thereby preventing a large amount of liquid from flowing at high speed. Alternatively, see Figure 2 The intersection line of the first baffle 14 and the connecting portion 12 can also be a straight line, so that the first guide groove 18 extends along a straight line. The first guide groove 18 extends along a straight line, and the slope of each part of the first guide groove 18 is the same. When the liquid flows along the first guide groove 18 to the confluence port 17, it can maintain a uniform speed.

[0046] In some embodiments, the intersection line of the second baffle 15 and the connecting portion 12 may be an arc line, so that the second guide groove 19 extends along the arc line. The second guide groove 19 extends along the arc line, and the slopes of the second guide groove 19 are different at different locations. When the liquid flows along the second guide groove 19 to the confluence port 17, as the slope of the second guide groove 19 gradually decreases, the flow rate of the liquid gradually decreases, thereby preventing a large amount of liquid from flowing at high speed. Or see Figure 2 The intersection line of the second baffle 15 and the connecting portion 12 can also be a straight line, so that the second guide groove 19 extends along a straight line. The second guide groove 19 extends along a straight line, and the slope of each part of the second guide groove 19 is the same. When the liquid flows along the second guide groove 19 to the confluence port 17, it can maintain a uniform speed.

[0047] The intersection line between the first baffle plate 14 and the connecting portion 12 and the intersection line between the second baffle plate 15 and the connecting portion 12 may both be arcs, or both be straight lines, or one of them may be a straight line and the other may be an arc.

[0048] In some embodiments, the angle between the intersection line of the first baffle 14 and the connecting portion 12 and the horizontal plane can be at least 10°-30°. The angle between the intersection line of the first baffle 14 and the connecting portion 12 and the horizontal plane can be 10°-30°, so that the first baffle 14 can have a larger interception length with less material and the blocked liquid has an appropriate flow rate. In a specific implementation, the angle between the intersection line of the first baffle 14 and the connecting portion 12 and the horizontal plane can be 12°, 15°, 18°, 20°, 25°, 28°, 30°.

[0049] In some embodiments, the angle between the intersection line of the second baffle 15 and the connecting portion 12 and the horizontal plane can be at least 10°-30°. The angle between the intersection line of the second baffle 15 and the connecting portion 12 and the horizontal plane can be 10°-30°, so that the second baffle 15 can have a larger interception length with less material and the blocked liquid has an appropriate flow rate. In a specific implementation, the angle between the intersection line of the second baffle 15 and the connecting portion 12 and the horizontal plane can be 12°, 15°, 18°, 20°, 25°, 28°, 30°.

[0050] In some embodiments, the connecting portion 12 includes an arc portion, and the outer edge of the arc portion is located on a circumference with the center of the air inlet duct 13 as the center. In an exemplary embodiment, the connecting portion 12 can be a substantially annular plate body extending from the outer edge of the guide portion, and the other portions of the connecting portion 12 other than the connection between the first baffle plate 14 and the second baffle plate 15 can maintain an annular shape.

[0051] In some embodiments, see Figure 5 The distance L1 from the center of the air inlet duct 13 to the intersection line of the first baffle 14 and the connecting portion 12 is not less than the distance L2 from the center of the air inlet duct 13 to the outer edge of the arc portion. A sufficient size is reserved at the connection with the first baffle 14 so that the connecting portion 12 can be connected to the wind cabinet 20, and the first baffle 14 can be flexibly arranged, so as to achieve the maximum blocking effect with less material and facilitate the installation of the air inlet ring 10.

[0052] In some embodiments, the distance L3 from the center of the air inlet duct 13 to the intersection line of the second baffle 15 and the connecting portion 12 is not less than the distance L2 from the center of the air inlet duct 13 to the outer edge of the arc portion.

[0053] In some embodiments, the air inlet ring 10 may be a plane-symmetrical structure, and the first baffle 14 and the second baffle 15 are respectively located on both sides of the symmetry plane, and the symmetry plane passes through the center line of the air inlet duct 13 .

[0054] In some embodiments, the length of the first guide groove 18 and the length of the second guide groove 19 may be the same or different.
