[0056] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0057] The oil guiding component 100 for a range hood 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0058] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the oil guiding component 100 of the range hood 1000 includes an upwardly extending air outlet pipe section 201, and the fan component 200 of the range hood 1000 includes an upwardly extending air outlet pipe section 201. Figure 3 The oil guiding component 100 has a clearance area 10 for avoiding the air outlet duct section 201, so that the oil guiding component 100 is adapted to be disposed around the air outlet duct section 201 through the clearance area 10. At least a portion of the lower surface of the oil guiding component 100 is constructed as an oil collecting and guiding surface 20 inclined to the horizontal plane. It should be noted that "disposed around the air outlet duct section 201" as described herein means that it is disposed at least on both sides of the air outlet duct section 201, and may be, but is not required to be, a complete circle. For example, it may be disposed on both sides, three sides, etc. of the air outlet duct section 201.

[0059] In related technologies, range hoods typically have a fan to create a negative pressure zone, thereby forming an airflow that carries away cooking fumes. To improve fume collection, the air intake area of ​​the range hood is usually located at the bottom of the hood, close to the stove where the fumes are generated. Under the suction of the fan, the fumes enter the fan's interior through the air intake mesh. Due to the airflow characteristics of the fumes themselves and the limited suction power of the fan, the fumes will inevitably disperse and collide with the inner wall of the casing, condensing into oil droplets. Especially at the edges, the oil droplets are prone to dripping from the edges, thus penetrating the air intake mesh and dripping onto the stove, affecting the user experience.

[0060] This invention guides the flow of oil 2000 by incorporating an oil-guiding component 100 within the range hood 1000. Oil fumes that would otherwise rise to the top of the inner wall of the housing 300 are blocked by the oil-guiding component 100, causing them to condense into liquid. The oil 2000 is then guided by the oil-collecting and guiding surface 20 of the oil-guiding component 100, reducing the likelihood of oil 2000 dripping from the air inlet mesh and preventing it from dripping onto the cooktop, thus improving the user experience. The oil-collecting and guiding surface 20 is inclined to a horizontal plane, allowing the oil 2000 to flow more rapidly under its own weight.

[0061] According to an embodiment of the present invention, the oil guiding component 100 for a range hood 100 guides the flow of oil 2000, preventing oil 2000 from dripping onto the stovetop and improving user experience. By setting an avoidance area 10, the oil guiding component 100 can surround the air outlet section 201 to maximize the setting area of ​​the oil guiding component, further reducing the probability of oil 2000 dripping from around the fan component 200, and more fully and comprehensively preventing oil 2000 from dripping from the range hood 1000 onto the stovetop, improving user experience. At the same time, the oil collection and guiding surface 20 facilitates the sliding of oil 2000 on the oil guiding component 100, improving guiding ability.

[0062] Furthermore, since the oil guiding component 100 is arranged around the air outlet section 201 of the fan component 200, the area of ​​the oil guiding component 100 can be reduced under the premise of the same horizontal projected area, thereby reducing the cost of the oil guiding component 100. It can also save the space occupied by the oil guiding component 100 in the range hood 1000, so that the range hood 1000 can have more space to accommodate other components, such as a baffle structure. Moreover, the installation position of the oil guiding component 100 is easier to achieve.

[0063] like Figure 4 As shown, in some embodiments, the angle between the oil collecting guide surface 20 and the horizontal plane (e.g.) Figure 4The angle A and the angle B shown in the figure are less than or equal to 50° and greater than or equal to 6° (for example, 50°, 30°, 20°, 10°, 6°, etc.), by setting the angle between the oil collecting and guiding surface 20 and the horizontal plane to be less than or equal to 50° and greater than or equal to 6°, both the cost is reduced and the sliding of the oil 2000 on the oil guiding component 100 is facilitated. It should be noted that the angle A and the angle B in the figure can be equal or not equal, and the angle A and the angle B can be respectively taken individually. For example, the angle A is 50° and the angle B is 10°, the oil 2000 on the first oil guiding plate 30 can slide faster from the top, the overall size of the second oil guiding plate 40 is smaller, thereby reducing the use of materials and reducing the cost; or the angle A is 20° and the angle B is 20°, the oil 2000 on the first oil guiding plate 30 and the second oil guiding plate 40 slides faster under the action of gravity, and the overall size is smaller, thereby reducing the cost.

[0064] For example, the angle between the oil collecting and guiding surface 20 and the horizontal plane is 6°, the overall size of the oil collecting and guiding surface 20 is smaller, thereby reducing the use of materials and reducing the cost, and the oil 2000 has a certain sliding ability; or the angle between the oil collecting and guiding surface 20 and the horizontal plane is 50°, the larger angle between the oil collecting and guiding surface 20 and the horizontal plane makes the oil 2000 on the oil collecting and guiding surface 20 slide faster, and the overall size of the oil collecting and guiding surface 20 is appropriate, thereby reducing the cost; or the angle between the oil collecting and guiding surface 20 and the horizontal plane is 28°, the oil 2000 on the oil collecting and guiding surface 20 slides faster under the action of gravity, and the overall size of the oil collecting and guiding surface 20 is smaller, thereby reducing the cost.

[0065] In some embodiments, the angle between the oil collecting and guiding surface 20 and the horizontal plane can be further less than or equal to 30° and greater than or equal to 10° (for example, 30°, 25°, 20°, 15°, 10°, etc.), by setting the angle between the oil collecting and guiding surface 20 and the horizontal plane to be less than or equal to 30° and greater than or equal to 10°, both the cost is further reduced and the sliding of the oil 2000 on the oil guiding component 100 is further facilitated.

[0066] For example, the angle between the oil collecting and guiding surface 20 and the horizontal plane is 10°, the overall size of the oil collecting and guiding surface 20 is smaller, thereby reducing the use of materials and reducing the cost, and the oil 2000 has a certain sliding ability; or the angle between the oil collecting and guiding surface 20 and the horizontal plane is 30°, the larger angle between the oil collecting and guiding surface 20 and the horizontal plane makes the oil 2000 on the oil collecting and guiding surface 20 slide faster, and the overall size of the oil collecting and guiding surface 20 is appropriate, thereby reducing the cost; or the angle between the oil collecting and guiding surface 20 and the horizontal plane is 20°, the oil 2000 on the oil collecting and guiding surface 20 slides faster under the action of gravity, and the overall size of the oil collecting and guiding surface 20 is smaller, thereby reducing the cost.

[0067] As shown in Figure 3 and Figure 4 In some embodiments, the oil guide component 100 includes: a first oil guide plate 30 and two second oil guide plates 40, the two second oil guide plates 40 are arranged on the same side of the first oil guide plate 30 in the second direction F2 and are spaced apart in the first direction F1 to form an avoidance area 10 between the first oil guide plate 30 and the two second oil guide plates 40, and the lower surface of the first oil guide plate 30 and the lower surface of the second oil guide plate 40 are both configured as oil collection and guiding surfaces 20. Wherein, the avoidance area 10 avoids the air outlet pipe section 201 of the fan component 200, the two second oil guide plates 40 are arranged on both sides of the air outlet pipe section 201, the oil guide component 100 forms a wrapped shape with the fan component 200, reduces the risk of oil 2000 dripping from the gap between the oil guide component 100 and the fan component 200, and improves user experience; the lower surfaces of the first oil guide plate 30 and the second oil guide plate 40 are both configured as oil collection and guiding surfaces 20, so that the oil 2000 on the first oil guide plate 30 and the second oil guide plate 40 can quickly slide, reducing the risk of oil 2000 accumulating on the first oil guide plate 30 and the second oil guide plate 40.

[0068] For example, the first direction F1 is the left-right direction, the second direction F2 is the front-back direction, the first oil guide plate 30 is in front of the fan component 200, and the two second oil guide plates 40 are respectively on the left and right sides of the fan component 200, forming an avoidance area 10 between the two second oil guide plates 40, which avoids the air outlet pipe section 201 of the fan component 200, thereby separating the inner wall surface of the top of the range hood 1000 from the air inlet mesh, and the rising oil fume is condensed on the oil guide component 100.

[0069] As shown in Figure 3 and Figure 4 In some embodiments, the lower surface of the first oil guide plate 30 extends downward in the second direction F2 along the direction from the first oil guide plate 30 to the second oil guide plate 40, so that the oil 2000 condensed on the first oil guide plate 30 can slide from the first oil guide plate 30 to the second oil guide plate 40, facilitating the collection of oil 2000.

[0070] As shown in Figure 3 , Figure 5As shown, in some embodiments, the side edge of the first oil guide plate 30 close to the second oil guide plate 40 has an extension section 31 extending downward, the lower end of the extension section 31 has an oil guide groove 311 extending downwardly and obliquely along the first direction F1, the lower surface of the first oil guide plate 30 is adapted to accumulate and guide the oil liquid 2000 to the extension section 31, the extension section 31 is adapted to guide the oil liquid 2000 to the oil guide groove 311, and the oil guide groove 311 is adapted to guide the oil liquid 2000 to slide downwardly and obliquely out. By arranging the extension section 31 and the oil guide groove 311, the oil liquid 2000 condensed on the first oil guide plate 30 is guided to slide to the oil guide groove 311 and then out, and in the whole process, the oil liquid 2000 is guided by the oil guide component 100, thereby reducing the probability of the oil liquid 2000 directly dropping onto the cooking bench, and in the whole process, the sliding of the oil liquid 2000 is caused by its own gravity, without the need of external power device for guidance, thereby reducing the cost.

[0071] As shown in FIG. 1, the oil guide component 100 is arranged on the cooking bench 1000, and the oil guide component 100 is arranged on the inner wall surface of the cabinet 300 of the range hood 1000. Figure 3 and Figure 5 Specifically, as shown in FIG. 1, the oil guide groove 311 guides the oil liquid 2000 to slide downwardly and obliquely to the inner wall surface of the cabinet 300 of the range hood 1000, and the inner wall surface is adapted to guide the oil liquid 2000 to slide to the oil cup 600 of the cabinet 300, and the oil liquid 2000 is guided throughout the process, thereby reducing the probability of the oil liquid 2000 dropping in the air without guidance and avoiding the oil liquid 2000 from falling onto the cooking bench through the air inlet net.

[0072] As shown in FIG. 1, the oil guide component 100 is arranged on the cooking bench 1000, and the oil guide component 100 is arranged on the inner wall surface of the cabinet 300 of the range hood 1000. Figure 3As shown, in some embodiments, the oil guide groove 311 includes two sub-grooves 3111 arranged sequentially along a first direction F1. The two sub-grooves 3111 extend downwards at an angle away from each other in the first direction F1. By setting the two sub-grooves 3111 to guide the discharged oil 2000, the distance the oil 2000 travels is reduced, and the time the oil 2000 exists in the oil guide groove 311 is reduced. It can be understood that the two sub-grooves 3111 are arranged sequentially along the first direction F1, and the oil 2000 guided by the extension section 31 can enter the two sub-grooves 3111 respectively. The distance the oil 2000 travels in the sub-grooves 3111 is shortened, thereby the time it exists in the sub-grooves 3111 is shorter. For example, the first direction F1 is the left-right direction. The two sub-slots 3111 are arranged sequentially in the left-right direction. The total length of the two sub-slots 3111 is the same as the length of the extension section 31. The two sub-slots 3111 are connected at the middle position of the extension section 31. The extension section 31 guides the oil 2000 to the two sub-slots 3111. The left sub-slot 3111 is tilted to the lower left, and the right sub-slot 3111 is tilted to the lower right. The oil 2000 guided to the left sub-slot 3111 automatically slides to the lower left on the surface of the sub-slot 3111 due to its own gravity, and is guided to the right sub-slot 3111. The oil 2000 on 1 automatically slides to the lower right on the surface of the sub-slot 3111 due to its own gravity. It can be understood that, compared to a sub-slot 3111 of the same length as the extension section 31, the sub-slot 3111 of the same length as the extension section 31 is inclined from left to right. If the oil 2000 on the sub-slot 3111 of the same length as the extension section 31 slides on the surface of the slot, it will inevitably move by the length of the extension section 31, resulting in an excessive movement distance. The present invention shortens the movement distance of the oil 2000 and shortens the time that the oil 2000 exists on the oil guide groove 311 by setting two sub-slots 3111.

[0073] like Figure 6 As shown, in some embodiments, the angle between the extending direction of the sub-groove 3111 and the horizontal plane (e.g.) Figure 6 In the diagram, the included angles θ1 and θ2 are less than or equal to 60° and greater than or equal to 5° (e.g., 60°, 40°, 20°, 10°, 5°, etc.). By setting the included angle between the extension direction of the sub-slot 3111 and the horizontal plane to be less than or equal to 60° and greater than or equal to 5°, both cost is reduced and the sliding of the oil 2000 on the sub-slot 3111 is facilitated. It should be noted that the included angles θ1 and θ2 in the diagram can be equal or unequal, and the included angles θ1 and θ2 can be taken as values ​​separately.

[0074] For example, the angle between the extension direction of the sub-groove 3111 and the horizontal plane is 5°, the overall size of the sub-groove 3111 is small, thereby reducing the use of materials and lowering the cost, and at the same time, the oil liquid 2000 has a certain sliding ability; or, the angle between the extension direction of the sub-groove 3111 and the horizontal plane is 60°, the larger angle between the extension direction of the sub-groove 3111 and the horizontal plane makes the oil liquid 2000 on the sub-groove 3111 slide faster, and at the same time, the overall size of the sub-groove 3111 is appropriate and the cost is low; or, the angle between the extension direction of the sub-groove 3111 and the horizontal plane is 32°, which makes the oil liquid 2000 on the sub-groove 3111 slide faster under the action of its own gravity, and at the same time, the overall size of the sub-groove 3111 is small and the cost is low.

[0075] In some embodiments, the angle between the extension direction of the sub-groove 3111 and the horizontal plane can be further less than or equal to 20° and greater than or equal to 10° (for example, 20°, 15°, 10°, etc.), by setting the angle between the extension direction of the sub-groove 3111 and the horizontal plane to be less than or equal to 20° and greater than or equal to 10°, the cost is further reduced and the sliding of the oil liquid 2000 on the sub-groove 3111 is further facilitated.

[0076] For example, the angle between the extension direction of the sub-groove 3111 and the horizontal plane is 5°, the overall size of the sub-groove 3111 is small, thereby reducing the use of materials and lowering the cost, and at the same time, the oil liquid 2000 has a certain sliding ability; or, the angle between the extension direction of the sub-groove 3111 and the horizontal plane is 60°, the larger angle between the extension direction of the sub-groove 3111 and the horizontal plane makes the oil liquid 2000 on the sub-groove 3111 slide faster, and at the same time, the overall size of the sub-groove 3111 is appropriate and the cost is low; or, the angle between the extension direction of the sub-groove 3111 and the horizontal plane is 32°, which makes the oil liquid 2000 on the sub-groove 3111 slide faster under the action of its own gravity, and at the same time, the overall size of the sub-groove 3111 is small and the cost is low.

[0077] As Figure 3 , Figure 5As shown, in some embodiments, the lower end of the extending section 31 has a bent edge section 312 bent upward, and the bent edge section 312 and the extending section 31 form an oil guiding groove 311, the bent edge section 312 blocks the movement of the oil 2000, avoids the oil 2000 from sliding out of the oil guiding groove 311, and the bent edge section 312 enhances the strength of the extending section 31. It can be understood that the extending section 31 is usually a plate, and the longer extending section 31 is prone to deformation, and the application sets the bent edge section 312 to bend upward and enhance the strength of the extending section 31, avoid the deformation of the first oil guiding plate 30, and it can be understood that the first oil guiding plate 30 is arranged in the range hood 1000, and the vibration of the fan 203 will certainly drive the vibration of the rest of the components of the range hood 1000 during the working process, and the application enhances the strength of the first oil guiding plate 30 to reduce the vibration.

[0078] It should be noted that the first oil guiding plate 30 and the two second oil guiding plates 40 can be separate parts and assembled together, or an integral part.

[0079] When the first oil guiding plate 30 and the two second oil guiding plates 40 can be separate parts and assembled together, for example Figure 7 As shown, in some embodiments, the side edge of the second oil guiding plate 40 close to the first oil guiding plate 30 has a connecting section 41 extending vertically, the connecting section 41 is attached to the extending section 31 and connected by a fastener, the connecting section 41 provides a position for the connection between the first oil guiding plate 30 and the second oil guiding plate 40, and facilitates the connection, and the connecting section 41 extends vertically, the extending section 31 also extends vertically, the connecting section 41 and the extending section 31 both extend vertically to facilitate the positioning of the two, and the fastener is used to connect the first oil guiding plate 30 and the second oil guiding plate 40 to improve the stability. For example, when connecting the first oil guiding plate 30 and the second oil guiding plate 40, the vertically extending connecting section 41 is attached to the vertically extending connecting section 41 to position the second oil guiding plate 40 relative to the first oil guiding plate 30, and then the fastener is used to connect the first oil guiding plate 30 and the second oil guiding plate 40 together.

[0080] In addition, the oil accumulated on the fastener can also slide downward along the extending section 31 to guide the flow, avoiding the problem of oil dripping from the fastener. The specific structure of the fastener is not limited, for example, it can be a screw, a rivet, etc. Of course, the assembly connection mode is not limited to this, for example, it can also be connected by plug-in, buckle connection, etc.

[0081] As Figure 4 and Figure 7As shown, in some embodiments, the lower surface of the second oil guide plate 40 extends downward at an angle in the second direction F2, along the direction from the first oil guide plate 30 to the second oil guide plate 40. This allows the oil 2000 condensed on the second oil guide plate 40 to automatically slide off under its own gravity, facilitating the collection of the oil 2000. For example, if the second direction F2 is the front-back direction, the first oil guide plate 30 is located in front of the second oil guide plate 40, and the second oil guide plate 40 extends downward at an angle in the front-back direction, the oil 2000 condensed on the second oil guide plate 40 will slide downward at an angle along the surface of the second oil guide plate 40 under its own gravity.

[0082] like Figure 7 As shown, in some embodiments, the side edge of the second oil guide plate 40 away from the first oil guide plate 30 has a downwardly extending guide section 42. The oil 2000 is guided by the guide section 42, and the guide section 42 extends downward so that the oil 2000 drips downward under its own gravity.

[0083] When the first oil guide plate 30 and the two second oil guide plates 40 are integrated as a single piece, for example Figure 8 As shown, in some embodiments, the first oil guide plate 30 and the two second oil guide plates 40 are integrally formed. By making the first oil guide plate 30 and the second oil guide plates 40 integrally formed, the number of processes is reduced, the structure is simplified, and it is easier to produce and manufacture. Of course, the construction as a single piece is not limited to this; for example, it can also be constructed as a single piece through processes such as welding.

[0084] like Figure 3 , Figure 8 As shown, in some embodiments, when the first oil guide plate 30 and the two second oil guide plates 40 are integrated, the lower surfaces of the first oil guide plate 30 and the second oil guide plate 40 both extend downwards at an angle in the second direction F2, from the first oil guide plate 30 to the second oil guide plate 40. By setting the lower surfaces of the first oil guide plate 30 and the second oil guide plate 40 to extend downwards at an angle in the second direction F2, it is further facilitated for the oil 2000 condensed on the oil guide component 100 to slide along the lower surfaces of the first oil guide plate 30 and the second oil guide plate 40, thereby guiding the flow of the oil 2000 and reducing the probability of the oil 2000 dripping from the air inlet mesh onto the stove.

[0085] like Figure 9As shown in the drawings, in some embodiments, the included angle between the lower surface of the first oil guide plate 30 and the horizontal plane is a first included angle C, the included angle between the lower surface of the second oil guide plate 40 and the horizontal plane is a second included angle D, the first included angle C is greater than the second included angle D, by setting the first included angle C greater than the second included angle D, the sliding speed of the oil liquid 2000 on the first oil guide plate 30 is faster, the sliding of the oil liquid 2000 is accelerated, the time of the oil liquid 2000 existing on the first oil guide plate 30 is reduced, at the same time, the second included angle D between the lower surface of the second oil guide plate 40 and the horizontal plane is less than the first included angle C, the size of the second oil guide plate 40 is reduced, and the cost is reduced. It can be understood that the first included angle C and the second included angle D are different, the included angles between the oil guide plates at different positions and the horizontal plane are different, so as to adapt to the requirements at different positions, reduce the cost and avoid the accumulation of the oil liquid 2000.

[0086] As shown in the drawings, Figure 8 As shown in the drawings, in some embodiments, when the first oil guide plate 30 and the two second oil guide plates 40 are an integral part, the side edge of the first oil guide plate 30 close to the second oil guide plate 40 has a guide section 32, the guide section 32 is connected between the two second oil guide plates 40 and extends downwardly along the first direction F1, the lower surface of the first oil guide plate 30 is adapted to accumulate the oil liquid 2000 and guide the oil liquid 2000 to the lower surface of the guide section 32, the guide section 32 is adapted to guide the oil liquid 2000 to the lower surface of the second oil guide plate 40, by setting the guide section 32 to guide the sliding of the oil liquid 2000, the movement of the oil liquid 2000 is further limited, and the probability of the oil liquid 2000 directly dropping from the air inlet net to the cooking bench is reduced. The oil liquid 2000 condensed on the first oil guide plate 30 slides along the lower surface of the first oil guide plate 30 to the guide section 32, the guide section 32 guides the oil liquid 2000 to the second oil guide plate 40, the whole movement process of the oil liquid 2000 is limited to be completed, so that the flow path of the oil liquid 2000 is clear, and the probability of the oil liquid 2000 dropping in the air and then falling on the cooking bench is reduced.

[0087] As shown in the drawings, Figure 8As shown, in some embodiments, the guiding section 32 comprises two sub-sections 321 arranged in sequence along the first direction F1, and the two sub-sections 321 extend downwardly in directions away from each other along the first direction F1, so as to guide the oil liquid 2000 toward the second oil guiding plates 40 on the two sides respectively. By arranging the two sub-sections 321 to guide the oil liquid 2000 to slide toward the second oil guiding plates 40 on the two sides, the moving path of the oil liquid 2000 is further defined, and the probability of the oil liquid 2000 dripping from the oil guiding component 100 is reduced. For example, the first direction F1 is the left-right direction, and the two sub-sections 321 are arranged left and right. The left sub-section 321 extends downwardly toward the lower left, and the right sub-section 321 extends downwardly toward the lower right, forming an eight-shaped bell mouth. The part of the oil liquid 2000 condensed on the first oil guiding plate 30 slides from the left sub-section 321 to the second oil guiding plate 40 on the left, and the rest of the oil liquid 2000 slides from the right sub-section 321 to the second oil guiding plate 40 on the right. The oil liquid flows from high to low along the left-right direction, reducing the probability of dripping from the front.

[0088] As shown in Figure 3 , Figure 8 Whether the first oil guiding plate 30 and the two second oil guiding plates 40 are separate parts and assembled together or are an integral part, in some embodiments, the side edge of the first oil guiding plate 30 away from the second oil guiding plates 40 has a first vertical extension section 34 extending vertically, and the first vertical extension section 34 has a first mounting portion 33 thereon, and / or the side edge of the second oil guiding plate 40 away from the first oil guiding plate 30 has a second vertical extension section 44 extending vertically, and the second vertical extension section 44 has a second mounting portion 43 thereon.

[0089] In this way, by arranging the vertical extension section for mounting at least at one of the two ends, the problem of accumulated oil directly dripping downward at the connection position can be avoided. Moreover, if the first mounting portion 33 and the second mounting portion 43 are arranged at the same time to fix the oil guiding component 100 on the cabinet 300 of the range hood 1000, the installation stability and convenience of the oil guiding component 100 can be improved.

[0090] It can be understood that the first vertical extension section 34 can extend downwardly or upwardly. The second vertical extension section 44 can extend downwardly or upwardly. For example Figure 3 and Figure 7 If the second vertical extension section 44 extends downwardly, it can be used as a flow guiding section 42.

[0091] For example, the side edge of the first oil guide plate 30 away from the second oil guide plate 40 has a first vertical extension section 34 extending vertically, and the first vertical extension section 34 has a first mounting portion 33; meanwhile, the side edge of the second oil guide plate 40 away from the first oil guide plate 30 has a second vertical extension section 44 extending vertically, and the second vertical extension section 44 has a second mounting portion 43. The oil guide component 100 is fastened to the cabinet 300 through the first mounting portion 33 and the second mounting portion 43, thereby improving stability. Alternatively, only the side edge of the first oil guide plate 30 away from the second oil guide plate 40 has a first vertical extension section 34 extending vertically, and the first vertical extension section 34 has a first mounting portion 33, thereby reducing cost. Alternatively, only the side edge of the second oil guide plate 40 away from the first oil guide plate 30 has a second vertical extension section 44 extending vertically, and the second vertical extension section 44 has a second mounting portion 43, thereby reducing cost.

[0092] For example, in some optional examples, in combination with Figure 3 and Figure 8 , the first mounting portion 33 is a through hole, and the cabinet 300 is provided with a screw corresponding to the through hole, and the screw is arranged in the through hole to fasten the first mounting portion 33 to the cabinet 300. In combination with Figure 3 , the second mounting portion 43 is a through hole, and the cabinet 300 is provided with a screw corresponding to the through hole, and the screw is arranged in the through hole to fasten the second mounting portion 43 to the cabinet 300. Alternatively, in combination with Figure 8 , the second mounting portion 43 is a pin, and the cabinet 300 is provided with a slot corresponding to the pin, and the pin can be inserted into the slot to fasten the second mounting portion 43 to the cabinet 300, thereby further improving the stability of the oil guide component 100.

[0093] Of course, the first mounting portion 33 can be a pin, the cabinet 300 is provided with a slot corresponding to the pin, and the second mounting portion 43 is a through hole, and the cabinet 300 is provided with a screw corresponding to the through hole. Alternatively, the first mounting portion 33 and the second mounting portion 43 are both through holes, and the cabinet 300 is provided with a screw corresponding to the through holes. Alternatively, the first mounting portion 33 and the second mounting portion 43 are both pins, and the cabinet 300 is provided with a slot corresponding to the pins.

[0094] Next, the oil extractor 1000 according to the first embodiment of the present application is described.

[0095] As shown in Figure 1 and Figure 2 , the oil extractor 1000 according to the embodiment of the present application includes a cabinet 300, a fan component 200, and an oil guide component 100.

[0096] The box 300 has an air inlet area 301, and the oil fume enters the box 300 through the air inlet area 301. For example, the air inlet area 301 is on the air inlet net, and of course, the air inlet area 301 can also be on other components, which will not be described here.

[0097] The fan component 200 is arranged in the box 300, and the fan component 200 has an air inlet 202 that communicates with the air inlet area 301. The fan component 200 forms a negative pressure space inside the range hood 1000, so that the oil fume can be sucked into the range hood 1000, and then discharged through the air outlet pipe section 201.

[0098] The oil guide component 100 is arranged in the box 300, and is the oil guide component 100 for the range hood 1000 in any of the above embodiments. The oil guide component 100 guides the flow path of the oil 2000, reducing the probability of oil 2000 falling on the cooking table.

[0099] According to the range hood 1000 of the embodiment of the present application, the flow of the oil 2000 is guided by the oil guide component 100, avoiding the oil 2000 from falling on the cooking table, and improving the user experience. The oil guide component 100 can surround the air outlet pipe section 201 by setting the avoidance area 10, reducing the probability of oil 2000 falling from the gap between the oil guide component 100 and the fan component 200, avoiding the oil 2000 from falling on the cooking table from the range hood 1000, improving the user experience, and setting the oil collecting and guiding surface 20 to facilitate the sliding of the oil 2000 on the oil guide component 100, improving the guiding ability.

[0100] As shown in Figure 1 , Figure 2 In some embodiments, the range hood 1000 further includes an electric control component 500 arranged above the oil guide component 100, and the electric control component 500 controls the operation of the fan component 200. It can be understood that the electric control component 500 is arranged above the oil guide component 100, and the oil fume that should rise to the electric control component 500 is prevented from condensing on the oil guide component 100, further reducing the probability of the oil 2000 falling on the cooking table.

[0101] As shown in Figure 1 , Figure 2As shown in the drawings, in some embodiments, the air inlet 202 is arranged on the front side of the fan component 200, the oil guide component 100 is the oil guide component 100 for the range hood 1000 described above, the first oil guide plate 30 is arranged on the front side of the air outlet pipe section 201, and the two second oil guide plates 40 are arranged on the left and right sides of the air outlet pipe section 201. By arranging the first oil guide plate 30 on the front side of the air outlet pipe section 201 and the two second oil guide plates 40 on the left and right sides of the air outlet pipe section 201, the inner wall surface at the top of the cabinet 300 is completely isolated from the air inlet area 301, and the probability of oil 2000 dripping from the gap between the oil guide component 100 and the air outlet pipe section 201 is reduced.

[0102] In some embodiments, the front end of the first oil guide plate 30 extends to the front plate 304 of the cabinet 300, the rear end of the second oil guide plate 40 extends to the rear plate 305 of the cabinet 300, the left and right ends of the first oil guide plate 30 extend to the left side plate 302 and the right side plate 303 of the cabinet 300, respectively, the left end of the left second oil guide plate 40 extends to the left side plate 302 of the cabinet 300, and the right end of the right second oil guide plate 40 extends to the right side plate 303 of the cabinet 300. By arranging the front end of the first oil guide plate 30 to extend to the front plate 304 of the cabinet 300, the rear end of the second oil guide plate 40 to extend to the rear plate 305 of the cabinet 300, the left and right ends of the first oil guide plate 30 to extend to the left side plate 302 and the right side plate 303 of the cabinet 300, respectively, the left end of the left second oil guide plate 40 to extend to the left side plate 302 of the cabinet 300, and the right end of the right second oil guide plate 40 to extend to the right side plate 303 of the cabinet 300, the top space of the cabinet 300 is further isolated from the air inlet area 301, the oil fume is condensed on the oil guide component 100, and then guided to flow by the oil guide component 100, further reducing the probability of oil 2000 dripping from the air inlet area 301 to the cooking bench, and improving user experience.

[0103] As shown in the drawings, Figure 2 In some embodiments, the fan component 200 includes a volute 204 and a fan 203, and the extension section 31 is attached to the front side of the volute 204, and the fan 203 is arranged in the volute 204. Among them, the folded edge section 312 on the extension section 31 guides the flow of oil 2000, reduces the accumulation of oil 2000 on the front side of the volute 204, and reduces the cleaning frequency. At the same time, it can be understood that when the first oil guide plate 30 and the second oil guide plate 40 are connected by screws, the folded edge section 312 can receive the condensed oil of the screw head, reducing the probability of dripping onto the cooking bench.

[0104] More specifically, the fan 203 is a centrifugal fan, the centrifugal fan has a centrifugal fan impeller, the centrifugal fan impeller is arranged in the volute 204, and the rear disc is mounted on the rotating shaft of the motor.

[0105] Next, the range hood 1000 according to the second embodiment of the present application is described.

[0108] The fan component 200 is arranged in the box 300, and the front side of the fan component 200 has an air inlet 202 which communicates with the air inlet area 301, by setting the fan component 200 to form a negative pressure space inside the range hood 1000, so that the oil fume can be sucked into the range hood 1000, and then discharged through the above-mentioned air outlet pipe section 201.

[0109] The oil guide component 100 is arranged in the box 300, and comprises a first oil guide plate 30 arranged in front of the fan component 200 and higher than the air inlet 202, and two second oil guide plates 40 arranged on the left and right sides of the fan component 200, the lower surface of the first oil guide plate 30 and the lower surface of the second oil guide plate 40 are all configured as an oil collecting and guiding surface 20 which is inclined to the horizontal plane.

[0110] By arranging the first oil guide plate 30 in front of the air outlet pipe section 201, and arranging the two second oil guide plates 40 on the left and right sides of the air outlet pipe section 201, the problem of oil accumulation and dripping on the top wall of the box 300 can be avoided as much as possible around the air outlet pipe section 201, and the oil collecting and guiding surface 20 is arranged to guide the flow of oil 2000, further reducing the probability of oil 2000 dripping onto the cooking bench. Moreover, under the premise of the same horizontal plane projection area, the area of the oil guide component 100 can be reduced, thereby reducing the cost of the oil guide component 100, and saving the space occupied by the oil guide component 100 in the range hood 1000, so that the range hood 1000 can have more space to accommodate other component devices, and the setting position of the oil guide component 100 is relatively easy to install.

[0111] According to the range hood 1000 of the embodiment of the present application, by setting the first oil guide plate 30 and the second oil guide plate 40 to guide the flow of oil 2000, and by setting the oil collecting and guiding surface 20 which is inclined to the horizontal plane to facilitate the flow of oil 2000.
