[0033] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0034] See Figures 1 to 3 , an embodiment of the present application provides a range hood, which includes a smoke hood 10, an oil cup 20 and a first oil guide plate 31. The smoke hood 10 includes a panel 11, a front panel 12 spaced apart above the panel 11, and a back panel 13 spaced apart behind the panel 11. The panel 11 and the front panel 12 form an upper air inlet 14. Among them, the surface where the panel 11 is located can be set at an angle to the back panel 13, and the distance between the bottom end of the panel 11 and the back panel 13 is smaller than the distance between the top end of the panel 11 and the back panel 13, that is, the bottom end of the panel 11 is extended obliquely toward the rear; the surface where the panel 11 is located can also be set parallel to the back panel 13, that is, it is set in the vertical direction. The oil cup 20 is set at the bottom of the smoke hood 10. The panel 11 and the bottom end of the smoke hood 10 are spaced apart and cooperate to form a lower air inlet 15. Please refer to Figure 2 、 Figure 4 and Figure 9 The first oil guide plate 31 is connected to the front plate 12. The first oil guide plate 31 is arranged at the upper air inlet 14, and the rear end of the first oil guide plate 31 extends downward at an angle relative to the back plate 13 and extends into the interior of the smoke hood 10, and is located on the rear side of the top end of the panel 11, that is, the rear end of the first oil guide plate 31 extends downward at an angle toward the rear, and is located on the rear side of the top end of the panel 11.

[0035] It should be noted that the back plate 13 refers to the plate on the smoke hood 10 that faces the wall when the smoke hood 10 is normally installed on the wall. Generally speaking, the wall is arranged in the vertical direction, and the back plate 13 is correspondingly arranged in the vertical direction, that is, Figure 1 or Figure 3As shown in , it is arranged in the up-down direction.

[0036] During use, some cooking fumes in the kitchen environment are drawn into the interior of the fume hood 10 through the lower air inlet 15, while the remaining portion is drawn into the interior of the fume hood 10 through the upper air inlet 14. Since the lower air inlet 15 is closer to the cooking surface, cooking fumes are more likely to enter the interior of the fume hood 10 through the lower air inlet 15. Fumes that do not enter the lower air inlet 15 will enter the upper air inlet 14 and be discharged there. Therefore, the amount of cooking fumes drawn into the lower air inlet 15 is greater than that drawn into the upper air inlet 14. The lower air inlet 15 can be defined as the primary air inlet, and the upper air inlet 14 can be defined as the secondary air inlet.

[0037] The above-mentioned range hood, on the one hand, can realize the dual suction and exhaust function of oil smoke due to the lower air inlet 15 and the upper air inlet 14; on the other hand, since it includes a first oil guide plate 31 connected to the front plate 12, the first oil guide plate 31 is arranged at the upper air inlet 14, and the rear end of the first oil guide plate 31 extends downward at an angle relative to the back plate 13 and extends into the interior of the smoke hood 10, and is located on the rear side of the top of the panel 11. Therefore, the oil stains generated by the upper air inlet 14 during the process of sucking and exhausting oil smoke will be guided by the first oil guide plate 31 and fall smoothly into the interior of the smoke hood 10, and finally enter the oil cup 20, which can effectively prevent the oil stains on the first oil guide plate 31 from falling to the outside of the smoke hood 10, and can also solve the problem of oil marks generated by the upper air inlet 14 when sucking and exhausting oil smoke. In addition, it uses fewer parts, has a simple structure, is easy to assemble, has a low cost, and improves product performance.

[0038] See also Figure 4 In one embodiment, the first oil deflector 31 is arranged at an angle to the panel 11, with the angle a1 being between 110° and 130°. This angle a1 is appropriately sized. A smaller a1 prevents oil stains from sliding down and falling outside the range hood. A larger a1 also minimizes resistance to oil smoke at the upper air inlet 14, thereby preventing any impact on the smoke extraction process.

[0039] In some embodiments, preferably, a1 includes but is not limited to 110°, 115°, 120°, 125° or 130°, etc., and can be flexibly adjusted and set according to actual needs.

[0040] In some embodiments, the panel 11 includes but is not limited to being set as a glass plate, etc., and can be flexibly adjusted and set according to actual needs.

[0041] In one embodiment, the distance between the bottom wall of the upper air inlet 14 and the top wall of the upper air inlet 14 is S1, and S1 is 10 mm to 20 mm. Specific examples include 10 mm, 12 mm, 15 mm, 18 mm, or 20 mm. Thus, the size of the distance S1 is appropriately set. On the one hand, the larger the distance S1 is, the better the smoking effect of the upper air inlet 14 is. On the other hand, the distance S1 is not too large, that is, the distance S1 is small enough, so as not to reduce the smoking effect at the lower air inlet 15, while also improving the appearance and quality of the product.

[0042] When the top of the panel 11 and the bottom of the front panel 12 cooperate to form the upper air inlet 14, the bottom wall of the upper air inlet 14 is, for example, the top of the panel 11, and the top wall of the upper air inlet 14 is, for example, the bottom of the front panel 12. Of course, the range hood may further include a first mounting plate connected to the first oil deflector 31. The first mounting plate is attached to the front panel 12, and the first mounting plate and the first oil deflector 31 are arranged at an angle and connected to each other.

[0043] See also Figure 4 、 Figure 6 and Figure 7 In one embodiment, the range hood further includes an oil guide shield 40 disposed within the fume hood 10 and connected to the panel 11. The oil guide shield 40 includes a second oil guide plate 41 disposed at an angle to the panel 11, with the rear end of the second oil guide plate 41 extending upward at an angle. The bottom of the oil guide shield 40 is provided with at least one oil leakage notch 401. Thus, the oil guide shield 40 serves as an oil guide, receiving oil that falls downward from the first oil guide plate 31. The received oil continues to flow downward through the oil leakage notch 401 to the oil cup 20.

[0044] Specifically, the vertical distance between the top of the second oil deflector 41 and the bottom of the first oil deflector 31 is smaller than the vertical distance between the top of the panel 11 and the bottom of the first oil deflector 31. Because the vertical distance between the top of the second oil deflector 41 and the bottom of the first oil deflector 31 is smaller than the vertical distance between the top of the panel 11 and the bottom of the first oil deflector 31, the oil deflector shielding member 40 also serves to block vision. When observing the upper air inlet 14 from the front of the smoke hood 10, the internal components of the range hood cannot be seen.

[0045] See also Figure 4In one embodiment, the vertical distance between the top of the second oil deflector 41 and the bottom of the first oil deflector 31 is S2, where S2 is ≤ 5 mm. S2 includes, but is not limited to, 5 mm, 4 mm, 3 mm, 2 mm, or 1 mm. This distance S2 is smaller than the threshold for human eyes to see the internal components of the range hood (specifically, the threshold is 5 mm, which can be adjusted based on different users or actual needs). Therefore, the internal components of the range hood cannot be seen. It can even be 0 mm, meaning that when viewed horizontally, the rear end of the second oil deflector 41 overlaps with the bottom end of the first oil deflector 31, making the internal components of the range hood impossible to see. Furthermore, it can be -1 mm, -2 mm, or -3 mm, meaning that when viewed horizontally, the rear end of the second oil deflector 41 overlaps with the bottom end of the first oil deflector 31, making the internal components impossible to see.

[0046] See also Figure 1 and Figure 4 In some embodiments, the upper air inlet 14 extends from the left side to the right side of the fume hood 10, and the first oil deflector 31 and the second oil deflector 41 each extend from the left side to the right side of the fume hood 10. Similarly, the lower air inlet 15 extends from the left side to the right side of the fume hood 10.

[0047] See also Figure 4 、 Figure 6 and Figure 7 In one embodiment, the oil-guiding shielding member 40 further includes a third oil-guiding plate 42 connected to the second oil-guiding plate 41 and arranged at an angle thereto. The third oil-guiding plate 42 is attached to the inner wall of the panel 11; an oil leakage notch 401 is formed at the connection between the second and third oil-guiding plates 41, 42. Thus, on the one hand, because the third oil-guiding plate 42 is attached to the inner wall of the panel 11, the oil-guiding shielding member 40 can be stably installed within the fume hood 10. On the other hand, the third oil-guiding plate 42 cooperates with the second oil-guiding plate 41 to form a V-shaped groove, which not only simplifies the structure and saves material costs, but also serves as an oil guide, directing oil contamination to the oil leakage notch 401, through which it flows to the oil cup 20.

[0048] In some embodiments, the third oil guide plate 42 is fixed to the inner wall of the panel 11 by adhesive, including but not limited to adhesive. The adhesive can be silicone adhesive, 502 strong adhesive, resin adhesive, etc.

[0049] In addition, the third oil guide plate 42 is tightly fitted to the inner wall of the panel 11 , thereby preventing a gap between the third oil guide plate 42 and the panel 11 from causing oil to flow into the gap.

[0050] See also Figure 3 、 Figure 4 and Figure 6In one embodiment, the range hood further includes a switch component 50 provided on the inner wall of the panel 11 and located below the oil guide shielding member 40. The switch component 50 and the oil leakage notch 401 are staggered in a direction from the top of the panel 11 to the bottom of the panel 11. Specifically, the switch component 50 is, for example, arranged in the middle position of the panel 11, and there are one or more oil leakage notches 401, which are arranged on the left and / or right side of the oil guide shielding member 40. In this way, when the oil collected by the oil guide shielding member 40 flows downward through the oil leakage notch 401, for example, when it flows downward from the left and / or right side of the panel 11 to the oil cup 20, it can avoid the switch component 50 located in the middle position of the panel 11, thereby not causing pollution to the switch component 50, and the service life of the switch component 50 is improved.

[0051] In one embodiment, the included angle between the second oil deflector plate 41 and the third oil deflector plate 42 is a2, where a2 is ≥ 60°. This allows the second oil deflector plate 41 and the third oil deflector plate 42 to form a V-shaped structure, simplifying the structure and saving material costs. Furthermore, a larger a2 maximizes the air intake area of the upper air inlet 14. If the angle is less than 60°, the area of the upper air inlet 14 is smaller, affecting the air intake effect.

[0052] See also Figure 4 In one embodiment, the third oil deflector plate 42 fits snugly against the top of the inner wall of the panel 11, with the top edge of the third oil deflector plate 42 aligned with the top edge of the panel 11. This ensures that the S2 value meets the required value while reducing the size of the oil deflector cover 40, thereby saving material costs. Furthermore, for range hoods with a switch 50 located on the inner wall of the panel 11, this prevents oil from flowing into the gap between the third oil deflector plate 42 and the panel 11 and then flowing down the inner wall of the panel 11, thereby preventing oil from contaminating the switch 50.

[0053] In one embodiment, the rear end of the first oil deflector plate 31 is located behind the third oil deflector plate 42 and in front of the rear end of the second oil deflector plate 41. This ensures that when oil droplets slide down from the first oil deflector plate 31, they fall into the groove of the oil deflector shield 40 and flow downward through the oil leakage gap 401 into the oil cup 20. This prevents oil droplets from flowing over the oil deflector shield 40 and directly onto the condensation plate at the lower air inlet 15 of the range hood, forming oil marks and affecting the user experience.

[0054] See also Figure 5 、 Figure 6 and Figure 8In one embodiment, the range hood further includes a fourth oil deflector 61. This fourth oil deflector 61 is connected to the panel 11 and positioned at the lower air inlet 15. The bottom of the fourth oil deflector 61 extends downwardly at an angle relative to the back panel 13 and into the interior of the fume hood 10. This serves to guide fumes into the lower air inlet 15 while also directing oil droplets from the oil leak notch 401 into the oil cup 20.

[0055] In some embodiments, the range hood further includes a second mounting plate 62. The second mounting plate 62 is connected to the top end of the fourth oil guide plate 61. The second mounting plate 62 is attached to the inner wall of the panel 11.
