[0029] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0030] like Figure 1-11 As shown in the figure, a range hood according to an embodiment of the present invention includes a housing 1, a cover 2, a first guide plate 3, and a second guide plate 4.

[0031] The housing 1 contains a blower 6. The lower end of the housing 1 has a first interface 11, and the upper end of the cover 2 has a second interface 21. The first interface 11 is inserted into the second interface 21.

[0032] The first guide plate 3 and the second guide plate 4 are respectively disposed inside the cover 2. The first guide plate 3 is located below the left side wall of the first interface 11, and the second guide plate 4 is located below the right side wall of the first interface 11. The first guide plate 3 and the second guide plate 4 are configured to receive the oil dripping from the left side wall and the right side wall of the first interface 11 respectively. The first guide plate 3 and the second guide plate 4 both have a first oil guiding installation angle a1 that is higher in the front and lower in the back, so as to guide the oil to the rear back plate 201 of the cover 2.

[0033] When oil droplets from the left side wall of the first interface 11 fall onto the first guide plate 3, the first guide plate 3 directs the oil to the rear back plate 201, where it flows into the oil collection box. Alternatively, the oil can drip directly from the rear end of the first guide plate 3 into the oil collection box, preventing oil droplets from the left side wall of the first interface 11 from passing through the oil filter and dripping onto the stove or cookware. Similarly, when oil droplets from the right side wall of the first interface 11 fall onto the second guide plate 4, the second guide plate 4 directs the oil to the rear back plate 201, where it flows into the oil collection box. Alternatively, the oil can drip directly from the rear end of the second guide plate 4 into the oil collection box, preventing oil droplets from the right side wall of the first interface 11 from passing through the oil filter and dripping onto the stove or cookware.

[0034] The first guide plate 3 also has a first air guide installation angle β1 with the left side lower and the right side higher, so as to guide the air intake on the left side into the first interface 11 in the middle. The second guide plate 4 also has a second air guide installation angle β2 with the left side higher and the right side lower, so as to guide the air intake on the right side into the first interface 11 in the middle, so that the air intake flows smoothly along the first guide plate 3 and the second guide plate 4 into the first interface 11 and the air handling unit 6, and is finally discharged through the air handling unit 6.

[0035] like Figure 1 , 2 As shown in Figures 5 and 7, in a preferred embodiment of this utility model, the first guide plate 3 includes a first base plate 31 and a first side plate 32. The first base plate 31 is located below the left side wall of the first interface 11, and the first base plate 31 has a first oil guiding installation angle α1 that is higher at the front and lower at the rear. The first oil guiding installation angle α1 is the angle between the first base plate 31 and the horizontal line H1, so that the first base plate 31 gradually decreases from front to back, allowing the oil to flow backward. For example, the first oil guiding installation angle α1 is 10-30 degrees.

[0036] The first base plate 31 also has a first air guide installation angle β1, which is lower on the left and higher on the right. The first air guide installation angle β1 is the angle between the first base plate 31 and the horizontal line H2, so that the first base plate 31 gradually tilts upward from left to right, thereby guiding the air intake on the left side to the first interface 11 located on the right side of the first base plate 31. For example, the first air guide installation angle β1 is 5-15 degrees.

[0037] The lower end of the first side plate 32 is fixedly connected to the right end of the first base plate 31. The upper end of the first side plate 32 is located inside the first interface 11, and there is a first gap between the upper end of the first side plate 32 and the lower end of the left side wall of the first interface 11. For example, the width of the first gap is equivalent to the maximum size of the oil droplet, or the width of the first gap is slightly larger than the maximum size of the oil droplet, so that the oil droplet can drip onto the first side plate 32 through the first gap. The first side plate 32 is configured to receive the oil dripping from the left side wall of the first interface 11 and guide it downward to the first base plate 31. The oil flows backward along the slope of the first base plate 31 to the rear back plate 201.

[0038] like Figure 5 , 7 As shown, in a preferred embodiment of this utility model, the upper end of the first side plate 32 is provided with an outwardly turned first oil-guiding flange 321. The first oil-guiding flange 321 is configured to increase the first gap to receive oil dripping from the oil accumulation area and guide the oil to the first side plate 32, preventing the oil dripping from the oil accumulation area from dripping outside the first guide plate 3. For example, the first oil-guiding flange 321 is turned 45 degrees to the right, so that the first oil-guiding flange 321 has an oil-guiding slope that is lower on the left and higher on the right.

[0039] like Figure 3 , 6 As shown in Figure 8, in a preferred embodiment of this utility model, the second guide plate 4 includes a second base plate 41 and a second side plate 42. The second base plate 41 is located below the right side wall of the first interface 11, and the second base plate 41 has a first oil guiding installation angle a1 that is higher in the front and lower in the back. The first oil guiding installation angle a1 is the angle between the second base plate 41 and the horizontal line H1, so as to realize that the second base plate 41 is higher in the front and lower in the back, so as to guide the dripping oil backward.

[0040] The second base plate 41 also has a second air guide installation angle β2, which is higher on the left and lower on the right. The second air guide installation angle β2 is the angle between the second base plate 41 and the horizontal line H2, so that the second base plate 41 gradually tilts upward from right to left, thereby guiding the air intake on the right side towards the first interface 11 located on the left side of the second base plate 41. For example, the second air guide installation angle β2 is 5-15 degrees.

[0041] The lower end of the second side plate 42 is fixed to the left end of the second bottom plate 41, and the upper end of the second side plate 42 is located inside the first interface 11. A second gap is formed between the upper end of the second side plate 42 and the lower end of the right side wall of the first interface 11. The second side plate 42 is configured to receive oil dripping from the right side wall of the first interface 11 and guide it to the second bottom plate 41. For example, the width of the second gap is equivalent to the maximum size of the oil droplet, or the width of the second gap is slightly larger than the maximum size of the oil droplet, so that the oil droplet can drip onto the second side plate 42 through the second gap and be guided downward to the second bottom plate 41. The oil flows backward along the slope of the second bottom plate 41 to the back plate 201.

[0042] like Figure 6 , 8 As shown, in a preferred embodiment of this utility model, the upper end of the second side plate 42 is provided with an outwardly turned second oil-guiding flange 421. The second oil-guiding flange 421 is configured to increase the second gap and guide the oil stains to the second side plate 42. The second oil-guiding flange 421 is used to receive dripping oil from the oil stain accumulation area and guide the oil stains to the second side plate 42, preventing the oil stains from the oil stain accumulation area from dripping outside the second guide plate 4.

[0043] like Figure 2 , 3 As shown in Figures 7 and 8, in a preferred embodiment of this utility model, both the first side plate 32 and the second side plate 42 are trapezoidal and are narrower at the front and wider at the back. The upper part of the first side plate 32 is detachably connected to the left wall plate of the second interface 21 by at least two first screws 211, and the upper part of the second side plate 42 is connected to the right wall plate of the second interface 21 by at least two second screws 212.

[0044] like Figure 7 , 8 As shown, in a preferred embodiment of this utility model, both the rear end of the first base plate 31 and the rear end of the second base plate 41 are provided with flanges 311, which are connected to the back plate 201. For example, the flanges 311 and the back plate 201 are fixedly connected by screws. Alternatively, the flanges 311 and the back plate 201 are hooked together by a hooking part.

[0045] The first base plate 31 and the second base plate 41 are respectively provided with oil outlets 312 on both sides of the flange 311. There is a gap between the wall of the oil outlet 312 and the back plate 201, and the oil drips into the oil collection box 2011 through the gap. Alternatively, it drips onto the back plate 201 and eventually flows into the oil collection box 2011 through the back plate 201.

[0046] like Figure 4 , 9 As shown, in a preferred embodiment of this utility model, the cover 2 has a main air inlet 22, a first auxiliary air inlet 23 located to the left of the main air inlet 22, and a second auxiliary air inlet 24 located to the right of the main air inlet 22.

[0049] The first base plate 31, the first side plate 32, the third side plate 33, and the fourth side plate 34 together form the first isolation section. The lower end of the sixth side plate 44 is connected to the inner wall of the cover 2. The second base plate 41, the second side plate 42, the fifth side plate 43, and the sixth side plate 44 together form the second isolation section. The first isolation section and the second isolation section divide the cavity of the cover 2 into an air cavity 25, a first mounting cavity 26, and a second mounting cavity 27. The first drive mechanism and the first lamp 212 are respectively disposed in the first mounting cavity 26, and the second drive mechanism and the second lamp 213 are respectively disposed in the second mounting cavity 27. Furthermore, one end of the connecting rod of the first drive mechanism and the connecting rod of the second drive mechanism are both located on the outside, thereby separating the air cavity 25 from the first drive mechanism, the second drive mechanism, the first lamp 212, and the second lamp 213, preventing oil stains from adhering to the first drive mechanism, the second drive mechanism, the first lamp 212, and the second lamp 213, and thus improving the service life of the drive mechanism and the lamp.

Oil dripping from the blower 6 falls into the oil collection box 7 through the second oil drain hole, and then flows into the oil guide pipe 8 through the third oil drain hole. It is then guided by the oil guide pipe 8 and drips onto the oil guide plate 5. Finally, it is guided by the oil guide plate 5 and drips onto the back plate 201, and flows along the back plate 201 into the oil collection box 2011. This guides the oil dripping from the blower 6 and prevents the oil dripping from the blower 6 from passing through the oil mesh and dripping onto the stove or cookware.

[0059] like Figure 11 As shown, in a preferred embodiment of this utility model, the front side plate 214 is provided with a lower air inlet 2141, which is connected to the air cavity 25. The oil guide plate 5 is located in the middle of the lower air inlet 2141, which divides the lower air inlet 2141 into a lower left air inlet corresponding to the left burner of the stove and a lower right air inlet corresponding to the right burner of the stove. This forces the airflow to deflect towards the burner areas on both sides, expands the negative pressure coverage area, accurately matches the position of the two burners, and achieves efficient capture of oil fumes.
