However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0028] The terms “a,” “one,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0029] This utility model embodiment provides a range hood, such as Figure 1-9As shown, the range hood includes a range hood housing 1, an oil cup 2, a fan assembly 3, an oil receiving assembly 4, and an oil guide plate 5. The fan assembly 3 includes a fan housing 31 and a fan 32 connected inside the fan housing 31. The range hood housing 1 has a side smoke inlet 11. The oil cup 2 is connected to the bottom of the range hood housing 1. The fan assembly 3 is connected to the top of the range hood housing 1 and includes a fan housing 31 and a fan 32 connected inside the fan housing 31. The oil receiving assembly 4 connects the fan housing 31 and the interior of the range hood housing 1, and is used to collect the oil generated by the fan 32 and guide it into the interior of the range hood housing 1. The top of the oil guide plate 5 is connected to the top of the smoke inlet, and the bottom of the oil guide plate 5 is inclined downward and backward and connected to the lower part of the rear wall of the range hood housing 1. The oil guide plate 5 is configured to collect the oil output by the oil receiving assembly 4 and guide the oil to the rear wall of the range hood housing 1. The oil can collect along the rear wall of the range hood housing 1 into the oil cup 2. In this application, the oil sludge generated by the fan 32 first collects in the oil receiving assembly 4, and then is guided by the oil receiving assembly 4 to the oil guide plate 5 located below it. The oil guide plate 5 receives the oil sludge output by the oil receiving assembly 4 and guides the oil sludge to the rear wall of the lower part of the range hood housing 1. The oil sludge collects in the oil cup 2 along the rear wall of the range hood housing 1. The oil sludge is guided to the rear wall below the range hood housing 1 by the oil guide plate 5, and then moves downward along the rear wall below the range hood housing 1. The oil sludge is then guided into the oil cup 2 through the oil passage hole on the range hood housing 1. The oil guide plate 5 can isolate the high-speed airflow from blowing away the oil sludge, preventing oil droplets from splashing or leaking; it eliminates the problem of traditional straight pipes being exposed, and integrates the oil guiding path of the air intake area corresponding to the side smoke inlet 11 below the range hood into a hidden design, ensuring a simple appearance of the range hood. In addition, the oil outlet end of the oil guide plate 5 is lower than the oil outlet end of the traditional straight pipe, and the oil guiding position is pressed downward to avoid the lower air intake path, while blocking the high-speed airflow from blowing away the oil droplets.

[0030] In a preferred embodiment of this utility model, such as Figure 2-8 The inclination angle of the oil guiding channel 50 shown is α, where 10°≤α≤20°. In this application, the internal space enclosed by the second flange 53 is the oil guiding channel 50. Therefore, the inclination angle of the oil guiding channel 50 is also the inclination angle of the oil guiding plate body 51. Preferably, it is 15°, which is 10°≤α≤20°. This inclination angle not only guides the oil to the lower part of the range hood housing 1, but also prevents the oil guiding plate body 51 from affecting the flue gas emission efficiency.

[0031] In a preferred embodiment of this utility model, such as Figure 1-8The range hood shown also includes an air guide plate 6. The bottom of the air guide plate 6 is connected to the bottom inner side of the range hood housing 1. The air guide plate 6 is inclined from bottom to top in a direction that gradually moves away from the side smoke inlet 11 and is connected to the bottom front side of the oil guide plate 5. That is, the oil outlet end of the oil guide plate 5 is located on the rear side of the air guide plate 6. The oil generated by the fan 32 passes through the oil receiving component 4 and the oil guide plate 5 in sequence and enters the rear of the air guide plate 6, and then enters the oil cup 2 through the oil hole. The oil guide plate 5 is installed behind the air guide plate 6, integrating the oil guiding path of the air intake area corresponding to the side smoke inlet 11 below the range hood into a hidden design, preventing oil from flowing to the front of the side smoke inlet, and also serving to shield the oil guide plate 5, blocking the high-speed airflow from blowing away the oil during operation, and preventing oil droplets from splashing or leaking. Furthermore, the oil guide plate 5 is centrally positioned at the side smoke inlet 11, and together with the air guide plate 6, it divides the side smoke inlet 11 into two symmetrical air intake channels on the left and right. This design forces the airflow to deflect towards the burner areas on both sides, expanding the negative pressure coverage area, precisely matching the positions of the two burners, and achieving efficient capture of oil fumes. Finally, the range hood of this application has dual air intakes, including a top smoke inlet and a side smoke inlet 11. The air guide plate 6 tilts upward and inward to form a "funnel effect," which not only gathers the diffused oil fumes towards the center, reducing lateral escape, lowering airflow resistance, and accelerating the speed at which oil fumes enter the range hood duct, but also prevents oil fumes from forming vortices below the range hood and compensates for the coverage height of the close-range suction by tilting upward. It can also work in conjunction with the top and side air intakes to form a three-dimensional capture network.

[0032] In a preferred embodiment of this utility model, such as Figure 1-8 The oil guide plate 5 shown includes a U-shaped oil guide plate body 51. The bottom of the oil guide plate body 51 is bent downward to form a second flange 53. The top of the air guide plate 6 is bent backward and downward to form a third flange 61. The middle part of the third flange 61 is bent backward and upward to form a fourth flange 62 corresponding to the first flange 52. The rear side of the fourth flange 62 abuts against the front side of the first flange 52. The fourth flange 62 and the first flange 52 are bolted together. The third flange 61 can increase the structural strength of the air guide plate 6, and the fourth flange 62 is used to adapt to the second flange 53 on the air guide plate 52, increasing the connection area between the two and ensuring the connection strength.

[0033] In a preferred embodiment of this utility model, such as Figure 1-8 The rear side of the range hood housing 1 shown is provided with a support 111 for limiting the second flange 53. The second flange 53 is connected between the support 111 and the air guide plate 6. The support 111 can strengthen the connection between the oil guide plate 5 and the range hood housing 1, and can evenly transfer the weight of the oil guide plate 5 to the range hood housing 1, reducing stress concentration at the connection and extending service life. It can also ensure that the oil guide plate 5 is always in the optimal airflow guiding position, ensuring precise fixation according to the preset airflow guiding angle.

[0034] The bottom of the air guide plate 6 is provided with a fifth flange 63, and the fifth flange 63 is provided with a locking hole 64. The range hood housing 1 is provided with a buckle 15 that connects to the locking hole 64, and the buckle 15 and the locking hole 64 are engaged. The buckle 15 and the locking hole 64 enable quick disassembly and installation of the air guide plate 6 and the range hood housing 1, thereby improving installation efficiency.

[0035] In a preferred embodiment of this utility model, such as Figure 1-9 The top of the oil guide plate body 51 shown is bent upward to form a second flange 53 for connecting the side smoke inlet 11. A reinforcing plate 12 is provided at the top of the side smoke inlet 11, wherein the reinforcing plate 12 has a mounting groove 121 corresponding to the second flange 53. The second flange 53 is inserted into and connected to the mounting groove 121 to achieve the connection between the second flange 53 and the reinforcing plate 12. The reinforcing plate 12 of this application is connected to the side of the side smoke inlet 11 near the top smoke inlet 11, which can increase the strength of the range hood housing 1 and also allow for the installation of a decorative panel assembly 7. The decorative panel assembly 7 of this application includes a bracket and a glass plate to improve the appearance of the range hood housing 1. Furthermore, the cooperation between the second flange 53 and the mounting groove 121 allows for the installation of the oil guide plate 5 without damaging the structure of the range hood housing 1, demonstrating an ingenious structure.

[0036] In a preferred embodiment of this utility model, such as Figure 1-9 The range hood housing 1 shown also includes a top smoke inlet 13 and an oil filter 14. The top smoke inlet 13 is located above the side smoke inlet 11 and is inclined upwards and outwards from the top of the reinforcing plate 12. The oil filter 14 connects the top smoke inlet 13 and the reinforcing plate 12. The top of the reinforcing plate 12 has a U-shaped groove 122 with its opening facing the oil filter 14, into which the oil filter 14 can be inserted. In this application, the inclined top smoke inlet 12 can more efficiently guide the rising fumes to the fan, enhancing the smoke extraction effect. In particular, when a large amount of fumes rises instantly, the inclined top smoke inlet 13 can expand the interception area, preventing fumes from overflowing from the front. Together with the side smoke inlet 12, it captures the rising fumes, and the two work together to reduce the diffusion of fumes, thereby expanding the negative pressure zone and improving smoke extraction efficiency. At the same time, the outwardly inclined top smoke inlet 12 is visually thinner, reducing the feeling of oppression and preventing head bumps. It also allows the oil filter 14 installed on it to be inclined, thus guiding oil and preventing oil stains from dripping onto the stove.

[0037] In a preferred embodiment of this utility model, such as Figure 1-9The bottom of the oil mesh 14 is provided with a sixth flange 141 for blocking oil. An oil drain hole 142, communicating with a U-shaped groove 122, is provided at the connection between the sixth flange 141 and the oil mesh 14. A decorative panel assembly 7 is connected to the outside of the reinforcing plate 12. The lower part of the decorative panel assembly 7 corresponds to the opening of the oil cup 2, allowing oil stains on the surface of the oil mesh 14 to fall into the oil cup 2 after passing through the sixth flange 141, the oil drain hole 142, the U-shaped groove 122, and the inner surface of the decorative panel assembly 7. In this way, the oil stains on the surface of the oil mesh 14 first enter the sixth flange 141, then enter the U-shaped groove 122 through the oil drain hole 142, and then flow from the U-shaped groove 122 to the surface of the reinforcing plate 12 and the decorative panel assembly 7 before entering the oil cup 2, achieving precise oil guiding of the oil mesh 14.

[0038] Preferred, such as Figure 1-8 The bottom of the oil mesh 14 shown is provided with a sixth flange 141 for blocking oil. The sixth flange 141 and the oil mesh 14 are inserted into the U-shaped groove 122. The U-shaped groove 122 and the sixth flange 141 are adapted to support the reinforcing plate 12 and the oil mesh 14.

[0039] Preferably, the middle part of the sixth flange 141 is provided with a seventh flange 143 that is bent inside the range hood housing 1. The upper groove wall of the U-shaped groove 122 is used for the seventh flange 143 to pass through the notch 1221, and both the left and right ends of the notch 1221 are provided with limiting blocks 1222 for limiting the seventh flange 143. The seventh flange 143 extends to the rear side of the range hood housing 1 through the notch 1221 and the two limiting blocks 1222. The two limiting blocks 1222 can realize the quick fixation of the oil screen 14 and the reinforcing plate 12.

[0040] In addition, the upper wall of the U-shaped groove 122 is provided with multiple connecting lugs 123, each of which is connected to the oil mesh 14. The connecting lugs 123 are used to increase the connection strength between the reinforcing plate 12 and the oil mesh 14.

[0041] In a preferred embodiment of this utility model, such as Figure 1-7 The top of the reinforcing plate 12 shown has mounting holes 124 for installing the decorative panel assembly 7 and rectangular holes 125 for guiding oil. Multiple oil drain holes 142 and rectangular holes 125 are provided, with at least one rectangular hole 125 on the outer periphery of each oil drain hole 142. The multiple mounting holes 124 ensure the connection strength between the decorative panel assembly 7 and the reinforcing plate 12. When the oil filter 14 accumulates due to excessive oil, some oil will flow to the sides of the oil filter 14. The rectangular holes 125 prevent this flow, allowing the oil to fall through the rectangular holes 125 onto the inner wall of the decorative panel assembly 7 and then flow into the oil cup 2, preventing the oil from dripping directly onto the outside of the range hood housing 1 after accumulation on the oil filter 14.

[0042] In a preferred embodiment of this utility model, such as Figure 1-7As shown, the oil receiving assembly 4 includes an oil receiving box 41 and an oil guide pipe 42. The oil receiving box 41 is located below the fan 32 to collect oil spills from the fan 32. One end of the oil guide pipe 42 is connected to the oil receiving box 41, and the other end extends downward to the top of the oil guide plate 5 to guide the oil spills in the oil receiving box 41 to the oil guide plate 5. After collecting the oil spills generated by the fan 32 and guiding them to the oil guide plate 5, the oil spills are then guided by the oil guide plate 5 to the oil cup 2.

[0043] In this embodiment of the invention, the term "multiple" refers to two or more, unless otherwise explicitly defined. The terms "install," "connect," and "fix" should be interpreted broadly. For example, "connect" can mean a fixed connection, a detachable connection, or an integral connection.
