Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a range hood. Background Art

[0002] At present, the smoke guide plate on the range hood is usually a flat plate, and the flat plate smoke guide plate forms a flow channel for air intake to improve the smoke extraction efficiency and improve the air performance.

[0003] However, in actual application, the smoke sources of the two stoves are respectively on the left and right sides of the range hood, close to the user's use direction, and the flat-plate smoke guide plate is approximately slightly outside the center of the cooker, and the flat-plate smoke guide plate blocks the direction of rising oil smoke almost vertically, making the flow of oil smoke not smooth, and even worse, causing adverse interference to the flow of oil smoke, causing the oil smoke to stay for a long time, have a long path, and easily leak. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention is to provide a range hood.

[0006] In view of this, according to a first aspect of the present invention, a range hood is provided, comprising a hood, a smoke inlet and at least two smoke guides, wherein the smoke inlet is arranged on the hood. At least two smoke guides are arranged on the hood, at least a portion of each smoke guide corresponds to the smoke inlet, the smoke guide comprises a first end and a second end opposite to each other, the first ends of at least two smoke guides are close to each other, the smoke guide comprises a smoke guide surface away from the smoke inlet, and the smoke guide surface comprises at least one curved surface segment between the first end and the second end.

[0007] The range hood provided by the present invention comprises a hood, a smoke inlet and at least two smoke guides. The hood is a hollow structure, and the oil smoke can enter the hood through the smoke inlet on the hood to be discharged to the outside. It is worth noting that the smoke inlet is arranged on the side of the hood close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood through the smoke inlet, solving the problem of long oil smoke flow path and long oil smoke residence time. The range hood also includes at least two smoke guides, at least two smoke guides are arranged on the hood, and at least a part of each smoke guide is arranged corresponding to the smoke inlet, so that the oil smoke can move more smoothly towards the smoke inlet under the guidance of the smoke guide, and finally enter the hood. Further, the smoke guide includes a first end and a second end opposite to each other, wherein the first ends of at least two smoke guides are close to each other, that is, the first end of the smoke guide is the inner end, and the second end of the smoke guide is the outer end, and the first end is arranged closer to the smoke inlet than the second end. It is worth noting that when the number of smoke guides is two, the two smoke guides are distributed side by side on the smoke hood in the left and right directions. Since in the related art, the number of stoves is two, and the two stoves are distributed in the left and right directions. The two smoke guides distributed on the left and right can well guide the smoke sources from the left and right directions. Furthermore, the smoke guide includes a smoke guide surface away from the smoke inlet, and the smoke guide surface includes at least one curved surface segment between the first end and the second end, that is, the smoke guide surface includes at least one curved surface segment in the left and right directions. At this time, the oil smoke generated by the smoke sources in the left and right directions can flow along the smoke guide surface including at least one curved surface segment, and the curved surface segment can better guide the oil smoke to the smoke inlet. The smoke guide can better adapt to the direction of the rising oil smoke, so that the flow of the oil smoke is smoother, avoiding adverse interference with the flow of the oil smoke, shortening the residence time of the oil smoke, and achieving the effect of limited smoke guidance. On the other hand, it can also solve the problem that the smoke guide has a large interference with the flow of the smoke source and a large noise.

[0008] It is worth noting that the smoke guide part has various structures, for example, the smoke guide part can be plate-shaped or a convex block structure, as long as the smoke guide surface of the smoke guide part facing away from the smoke inlet includes at least one curved surface segment. Further, the smoke guide surface can include a curved surface segment, or a curved surface segment and a flat surface segment.

[0009] In a possible design, further, the smoke guide part includes a smoke guide plate, the smoke guide plate includes a first plate body and a second plate body connected to each other, the first plate body is closer to another smoke guide part than the second plate body, and the first plate body and the second plate body are connected in a smooth transition.

[0010] In this design, the smoke guide part includes a smoke guide plate, that is, the smoke guide part is a plate-shaped structure, which can reduce the weight of the range hood itself on the basis of achieving effective smoke guidance, and adapt to the lightweight development trend of range hoods. Further, the smoke guide plate includes a first plate body and a second plate body connected, and the first plate body is arranged closer to the other smoke guide part than the second plate body, that is, the first plates of the two smoke guide parts are close to each other, and the second plates of the two smoke guide parts are far away from each other. The first plate body and the second plate body are connected in a smooth transition, that is, the connection between the first plate body and the second plate body is in an arc shape, and the connection between the second plate body and the first plate body is in a smooth transition shape on the side away from the smoke inlet. When the oil smoke rises, it attaches and diverts at the connection between the first plate body and the second plate body. At this time, the first plate body and the second plate body connected in a smooth transition will not hinder the flow of the oil smoke. At this time, a part of the oil smoke can flow along the first plate body, that is, along the inner side to the smoke inlet, and a part of the oil smoke can also flow along the second plate body, that is, along the outer side to the smoke inlet. The smoke guiding surface of the smoke guide plate formed by the first plate body and the second plate body can be streamlined. The first plate body can well guide the oil smoke on the inner side of the center of the stove, and the second plate body can well guide the oil smoke on the outer side of the center of the stove. The coordinated guiding effect of the first plate body and the second plate body can enable the oil smoke to achieve a good wall-attaching effect in multiple directions, minimize the resistance encountered by the oil smoke during the flow process, shorten the smoke residence time, and make it more unobstructed, thereby achieving effective smoke guiding.

[0011] Further, the first plate body includes a first smoke guiding surface facing away from the smoke inlet, the second plate body includes a second smoke guiding surface facing away from the smoke inlet, and the first smoke guiding surface and / or the second smoke guiding surface include a curved surface segment.

[0012] In a possible design, further, the first plate body includes a free end and a connecting end connected to the second plate body, and the distance between the free end of the first plate body and the plane where the smoke inlet is located is smaller than the distance between the connecting end and the plane where the smoke inlet is located.

[0013] In this design, the first plate body includes a free end and a connecting end, and the free end of the first plate body is close to the center of the smoke inlet. The connecting end of the first plate body is connected to the second plate body. The distance between the free end of the first plate body and the plane where the smoke inlet is located is smaller than the distance between the connecting end and the plane where the smoke inlet is located, that is, the first plate body is inclined relative to the plane where the smoke inlet is located. Furthermore, along the direction from the connecting end of the first plate body to the free end of the first plate body, the distance between the first smoke guide surface of the first plate body and the plane where the smoke inlet is located gradually decreases. Furthermore, the first smoke guide surface is curved. Specifically, when the oil smoke rises to the smoke guide plate, the oil smoke can flow to the smoke inlet along the inclined first plate body, reducing the resistance in the flow of the oil smoke, and at the same time guiding the flow so that the oil smoke can smoothly condense on the wall.

[0014] In a possible design, further, the length of the first plate body is greater than or equal to the length of the second plate body.

[0015] In this design, in the left-right direction, the length of the first plate is greater than that of the second plate, and in the front-back direction, the length of the first plate is equal to that of the second plate. This is because the first plate is arranged closer to the smoke inlet relative to the second plate, and the fan of the range hood can form a large negative pressure at the smoke inlet, which can strongly attract the oil smoke, making the length of the first plate greater than that of the second plate, so that most of the oil smoke can be guided to the smoke inlet through the first plate. Since the second plate is slightly farther away from the smoke inlet, the negative pressure there is smaller, so the length of the second plate is correspondingly smaller, so that a small part of the oil smoke can be guided along the second plate on the outside. By forming a streamlined smoke guide plate with different lengths of the first plate and the second plate, the oil smoke that deviates from the center of the smoke source can be guided, which is more suitable for the rising characteristics of the smoke source.

[0016] In a possible design, further, the smoke guide portion also includes a third plate body, and the third plate body is connected to the front end of the first plate body and / or the second plate body.

[0017] In this design, the smoke guide part also includes a third plate body, and the third plate body is connected to the front end of the first plate body, and / or the third plate body is connected to the front end of the second plate body. The third plate body is used to guide the oil smoke on the front side, so that the oil smoke on the front side can flow to the smoke inlet more smoothly through the guidance of the third plate body. It is worth mentioning that the third plate body includes a third smoke guide surface facing away from the smoke inlet, and the third smoke guide surface is a plane and / or a curved surface. It is worth mentioning that the front end of the first plate body and / or the second plate body refers to the end close to the user. When the installation position of the range hood is determined, the direction of the first plate body and the second plate body facing the user is the front.

[0018] In a possible design, further, the free end of the second plate body extends toward a direction close to the smoke inlet.

[0019] In this design, the second plate body includes a free end and a connecting end, and the connecting end of the second plate body is connected to the connecting end of the first plate body. The free end of the second plate body is bent / bent and extended toward the direction close to the smoke inlet, so as to better guide the oil smoke biased to the outside to the oil inlet. The second plate body is curved, and the distance between the free end of the second plate body and the plane where the smoke inlet is located is smaller than the distance between the connecting end of the first plate body and the plane where the smoke inlet is located. Specifically, the longitudinal section of the first plate body and the second plate body is U-shaped.

[0020] In a possible design, further, the free end of the third plate body extends toward a direction close to the smoke inlet.

[0021] In this design, the third plate body includes a connecting end and a free end, the connecting end of the third plate body is connected to the first plate body and / or the second plate body, and the free end of the third plate body is bent / curved and extended toward the direction close to the smoke inlet, so as to better guide the oil smoke biased to the front side to the oil inlet. The third plate body is curved.

[0022] Specifically, the smoke guide part formed by the first plate body, the second plate body and the third plate body is in the shape of a water droplet, and has a smooth surface, so that the resistance encountered by the oil smoke during the movement is minimal. Specifically, the smoke guide part formed by the first plate body, the second plate body and the third plate body protrudes in the direction away from the smoke inlet to form an arc-shaped smoke guide surface, so that the oil smoke biased to the outside, biased to the inside and biased to the front can be better guided. Since the smoke guide part has a streamlined curved structure, from the center of the smoke source, part of the oil smoke biased to the outside will pass through the second plate body wall, and then flow to the smoke inlet. From the center of the smoke source, part of the oil smoke biased to the inside will pass through the first plate body wall, and then flow to the smoke inlet. From the center of the smoke source, part of the oil smoke biased to the outside will pass through the third plate body wall, flow toward the smoke inlet, and finally enter the inside of the smoke hood through the smoke inlet.

[0023] In a possible design, further, the smoke guiding portion forms a receiving cavity, and at least a portion of the receiving cavity corresponds to the smoke inlet.

[0024] In this design, since the free ends of the second plate body and the third plate body are bent or extended toward the smoke inlet, the smoke guide plate composed of the first plate body, the second plate body and the third plate body can form a accommodating cavity with an opening toward the smoke inlet. During the flow of oil smoke, since the oil will move downward due to gravity, part of the oil can fall into the accommodating cavity formed by the smoke guide part, that is, the accommodating cavity formed by the smoke guide part itself, which can collect the oil to a certain extent, thereby solving the problem that the oil falls directly on the stove and is difficult to clean, or the problem that the oil cannot be collected when the smoke guide part is flat.

[0025] In a possible design, further, the first plate body includes a flat plate and / or a curved plate, the second plate body includes a flat plate and / or a curved plate, and the third plate body includes a flat plate and / or a curved plate.

[0026] In this design, the first plate body includes a flat plate and / or an arc-shaped plate, that is, the first smoke-guiding surface of the first plate body facing away from the smoke inlet is in the shape of a curved surface, or a combination of a flat surface and a curved surface, or a flat surface. Similarly, the second plate body and the third plate body can also be flat plates and / or arc-shaped plates, and the structures of the first plate body, the second plate body and the third plate body are diversified, so that the smoke-guiding surface of the smoke-guiding plate can present a variety of flow-guiding paths.

[0027] In a possible design, further, the smoke guide portion is an integrated structure.

[0028] In this design, the smoke guide part is an integrated structure, that is, the first plate body, the second plate body and the third plate body are an integrated structure. Because the integrated structure has good mechanical properties, it can improve the connection strength between the first plate body, the second plate body and the third plate body. In addition, the first plate body, the second plate body and the third plate body can be made into one piece and mass-produced to improve the processing efficiency of the product and reduce the processing cost of the product. In addition, by designing the first plate body, the second plate body and the third plate body as an integrated structure formed in one piece, the integrity of the smoke guide part is improved, the number of parts is reduced, the installation process is reduced, the installation efficiency is improved, and the installation of the smoke guide part is more convenient and reliable.

[0029] In a possible design, further, the range hood includes at least one connecting frame, and the at least one connecting frame is arranged between the hood and the smoke guide portion, and there is a first gap between the smoke guide portion and the hood.

[0030] In this design, the range hood further comprises at least one connecting frame, which is arranged between the smoke hood and the smoke guide part, that is, for each smoke guide part, there is at least one connecting frame connecting it with the smoke hood. Under the action of the at least one connecting frame, there is a first gap between the smoke hood and the smoke guide part, and the first gap can guide the oil smoke on the outer side and the oil smoke on the front side to the smoke inlet through the second plate body and the third plate body.

[0031] It is worth noting that, for each smoke guide part, there are two connecting frames, and the two connecting frames are arranged at intervals, so as to provide more stable support for the smoke guide part.

[0032] In a possible design, further, the smoke guide portion is detachably connected to at least one connecting frame.

[0033] In this design, the smoke guide part is detachably connected to at least one connecting frame, that is, the smoke guide part and the connecting frame are both detachably connected, so that the user can easily separate the smoke guide part from the smoke hood and clean the independent smoke guide part, thereby reducing the difficulty of cleaning the smoke guide part. Since the smoke guide part has the function of collecting oil, a lot of oil will accumulate in the accommodating cavity formed by the smoke guide part under long-term use, and it will be necessary to clean the oil in the smoke guide part.

[0034] In a possible design, further, at least one connecting frame is rotatably connected to the smoke hood and / or the smoke guide portion.

[0035] In this design, at least one connecting frame is rotatably connected to the smoke hood. And / or at least one connecting frame is rotatably connected to the smoke guide part. In other words, at least one of the two ends of each connecting frame is rotatably connected, so that the angle of the smoke guide part relative to the smoke hood can be easily adjusted to adapt to different smoke guiding requirements. When the position of the smoke source changes, the smoke guide part can be rotated to adjust the guide angle of the smoke guide part. Specifically, both ends of the connecting frame are rotatably connected to the smoke hood and the smoke guide part, one end of the connecting frame is rotatably connected to the smoke hood or the smoke guide part, and the other end of the connecting frame is fixedly connected to the smoke guide part or the smoke hood.

[0036] In a possible design, further, there is a second gap between the two smoke guiding parts, and the second gap is connected to the smoke inlet.

[0037] In this design, there is a second interval between the first ends of the two smoke guides, that is, the two smoke guides are arranged in parallel on the smoke hood in the left and right directions. Specifically, the parallel structure of the two smoke guides can solve the problem that the posture of the smoke guides is inconsistent with the flow direction of the oil smoke on the left and right sides, which easily leads to large interference with the flow of oil smoke, long residence time of oil smoke, long path, and easy smoke leakage. Furthermore, the second interval is connected to the smoke inlet, and the oil smoke biased to the inside can enter the smoke inlet through the second interval under the guidance of the smoke guide. By setting the second interval, an oil smoke channel is formed, and the width of the second interval can be designed according to the actual smoke guiding needs. Since the negative pressure formed by the fan is large at the position close to the smoke inlet, the oil smoke can be concentrated to flow toward the center by setting the second interval, and quickly enter the inside of the smoke hood through the second interval and the smoke inlet.

[0038] Furthermore, by setting a second interval between the two smoke guides, it is possible to avoid the problem that a single smoke guide causes the oil smoke to adhere to the wall for too long, causing the oil smoke generated by multiple smoke sources to collide and escape in the middle area of ​​the smoke guide.

[0039] In a possible design, further, the range hood includes an oil baffle, which is arranged on the hood and located on a side of the smoke guide portion away from the smoke inlet, and at least a portion of the oil baffle is arranged corresponding to the second interval.

[0040] In this design, the range hood also includes an oil baffle, which is arranged on the hood and located on the side of the smoke guide part away from the smoke inlet. At least a portion of the oil baffle is arranged corresponding to the second interval. The oil baffle is used to block oil and guide smoke. The position of the oil baffle can be set to adjust the smoke intake at the second interval, that is, between the two smoke guide parts, thereby avoiding the problem of too much or too little smoke intake at the second interval, which is beneficial to reduce the blockage of oil smoke entering the hood, thereby improving the oil fume emission efficiency.

[0041] In a possible design, the oil baffle further includes a bottom plate and two smoke guide plates, the bottom plate is connected to the smoke hood, the two smoke guide plates are respectively arranged on both sides of the bottom plate, and the free ends of the smoke guide plates extend close to the smoke guide portion, wherein the bottom plate and the two smoke guide plates form an oil containing cavity.

[0042] In this design, the oil baffle comprises a bottom plate and two smoke guide plates, the bottom plate is connected to the smoke hood, and the bottom plate has two opposite sides in the width direction. It is worth noting that the width direction is the left and right direction. The two smoke guide plates are respectively arranged on the left and right sides of the bottom plate, and one smoke guide plate extends toward a smoke guide portion close to it. Specifically, the two smoke guide portions include a first smoke guide portion and a second smoke guide portion, and the two smoke guide plates corresponding to the two smoke guide portions include a first smoke guide plate and a second smoke guide plate, the first smoke guide plate extends close to the first smoke guide portion, and the second smoke guide plate extends close to the second smoke guide portion. In this way, the bottom plate, the first smoke guide plate and the second smoke guide plate jointly enclose an oil containing cavity. In other words, the oil baffle jointly defined by the bottom plate and the two smoke guide plates has a cross-section similar to a U-shape, so that the oil containing cavity is an open groove-shaped structure, and the opening of the oil containing cavity is toward the direction of the smoke inlet. During the operation of the range hood, the condensed oil can fall into the oil containing cavity for collection.

[0043] Furthermore, an oil cup is provided at the bottom of the smoke hood. The oil cup is a long groove-shaped structure, and the oil cup is located at the bottom of the two smoke guide parts and the oil baffle, so that the oil cup can collect the oil entering from the oil chamber.

[0044] In a possible design, further, the inner wall of the smoke hood forms a smoke exhaust channel, and a part of the outer wall of the smoke hood forms a smoke guide cavity, which is connected to the smoke exhaust channel through the smoke inlet, and the smoke guiding part is connected to the outer wall of the smoke hood and is located in the smoke guide cavity, wherein the smoke guide cavity is gradually tapered from the opening of the smoke guide cavity to the smoke inlet.

[0045] In this design, the inner wall of the smoke hood forms a smoke exhaust channel, and a part of the outer wall of the smoke hood forms a smoke guide cavity, which is connected to the smoke exhaust channel through the smoke inlet. The smoke guide part is connected to the outer wall of the smoke hood, and the smoke guide part is located in the smoke guide cavity. From the opening of the smoke guide cavity to the smoke inlet, that is, in the direction from bottom to top, the smoke guide cavity is gradually contracted, that is, the smoke guide cavity is in the shape of a reverse funnel, which can facilitate the collection of oil smoke from the surroundings to the smoke inlet in the middle.

[0046] In a possible design, further, the range hood includes a fan, which is arranged in the smoke exhaust channel, and the fan can guide the airflow to enter the smoke exhaust channel through the smoke guide part and the smoke inlet.

[0047] In this design, the fan is arranged in the smoke hood, and the fan and the smoke guide are respectively located on both sides of the plane where the smoke inlet is located. The fan can disturb the airflow, thereby guiding the oil smoke at the smoke source to enter the smoke hood through the first interval, the second interval, and the smoke inlet through the smoke guide. Specifically, the smoke hood includes a hood body and a machine body, the machine body and the hood body are similar to a T-shape, the fan is arranged in the machine body, a part of the outer wall of the hood body forms a smoke guide cavity, and the smoke guide part is arranged on the hood body.

[0048] It is worth noting that the rotation axis of the fan is parallel to the wall on which the range hood is installed.

[0049] In a possible design, the range hood further includes an oil filter, which is arranged on the hood and located at the smoke inlet.

[0050] In this design, the oil filter is arranged on the smoke hood. When the oil smoke passes through the smoke inlet, it can be filtered by the oil filter, so that the oil adheres to the oil filter. After part of the oil smoke condenses, it may fall due to gravity, and the oil can fall into the oil baffle through the second interval.

[0051] It is worth noting that the oil filter is installed at the smoke inlet, and a first smoke guide plate and a second smoke guide plate are arranged below the oil filter. The first smoke guide plate and the second smoke guide plate are arranged in parallel on the left and right sides, and the two smoke guide plates and the oil filter form a series structure in the vertical direction, that is, the oil smoke first passes through the two smoke guide plates and then flows through the oil filter. The two smoke guide plates can form a streamlined curved structure, thereby achieving reasonable guidance of the oil smoke.

[0073] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0074] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0075] Refer to the following Figures 1 to 9 Some embodiments provided according to the present application are described.

[0076] Embodiment 1

[0077] like Figure 1 , Figure 4 and Figure 5 As shown, according to a first aspect of the present invention, a range hood 100 is provided, which includes a smoke hood 110, a smoke inlet 120 and at least two smoke guides, wherein the smoke inlet 120 is provided on the smoke hood 110. At least two smoke guides are provided on the smoke hood 110, at least a portion of each smoke guide corresponds to the smoke inlet 120, the smoke guide includes a first end and a second end opposite to each other, the first ends of at least two smoke guides are close to each other, the smoke guide includes a smoke guide surface 130a away from the smoke inlet 120, and the smoke guide surface 130a includes at least one curved surface segment between the first end and the second end.

[0078] The range hood 100 provided by the present invention includes a hood 110, a smoke inlet 120 and at least two smoke guides. The hood 110 is a hollow structure, and the oil smoke can enter the interior of the hood 110 through the smoke inlet 120 on the hood 110 to be discharged to the outside. It is worth noting that the smoke inlet 120 is arranged on the side of the hood 110 close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood 110 through the smoke inlet 120, solving the problem of the long flow path of the oil smoke and the long residence time of the oil smoke. The range hood 100 also includes at least two smoke guides, at least two smoke guides are arranged on the hood 110, and at least a part of each smoke guide is arranged corresponding to the smoke inlet 120, so that the oil smoke can move more smoothly towards the smoke inlet 120 under the guidance of the smoke guide, and finally enter the hood 110. Further, the smoke guide portion includes a first end and a second end facing each other, wherein the first ends of at least two smoke guide portions are close to each other, that is, the first end of the smoke guide portion is an inner end, the second end of the smoke guide portion is an outer end, and the first end is arranged closer to the smoke inlet 120 than the second end. It is worth noting that when the number of smoke guide portions is two, the two smoke guide portions are arranged side by side on the smoke hood 110 in the left and right directions. Since in the related art, the number of stoves is two, and the two stoves are arranged in the left and right directions. The two smoke guide portions arranged in the left and right directions can well guide the smoke source from the left and right directions. Furthermore, the smoke guiding portion includes a smoke guiding surface 130a facing away from the smoke inlet 120, and the smoke guiding surface 130a includes at least one curved surface segment between the first end and the second end, that is, the smoke guiding surface 130a includes at least one curved surface segment in the left and right directions. At this time, the oil smoke generated by the smoke sources in the left and right directions can flow along the smoke guiding surface 130a including at least one curved surface segment, and the curved surface segment can better guide the oil smoke to the smoke inlet 120. The smoke guiding portion can better adapt to the direction of rising oil smoke, making the flow of oil smoke smoother, avoiding adverse interference with the flow of oil smoke, shortening the residence time of oil smoke, and achieving the effect of limited smoke guiding. On the other hand, it can also solve the problem that the smoke guiding portion has a large interference with the flow of smoke source and a large noise.

[0079] It is worth noting that the structure of the smoke guide portion is diverse, for example, the smoke guide portion can be plate-shaped or a convex block structure, as long as the smoke guide surface 130a of the smoke guide portion facing away from the smoke inlet 120 includes at least one curved surface segment. Further, the smoke guide surface 130a can include a curved surface segment, or a curved surface segment and a flat surface segment.

[0080] Furthermore, if Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the smoke guide portion includes a smoke guide plate 130, and the smoke guide plate 130 includes a first plate body 1301 and a second plate body 1302 connected to each other. The first plate body 1301 is closer to another smoke guide portion than the second plate body 1302, and the first plate body 1301 and the second plate body 1302 are connected in a smooth transition.

[0081] In this embodiment, the smoke guide portion includes a smoke guide plate 130, that is, the smoke guide portion is a plate-shaped structure, which can reduce the weight of the range hood 100 on the basis of achieving effective smoke guidance, and adapt to the lightweight development trend of the range hood 100. Further, the smoke guide plate 130 includes a first plate body 1301 and a second plate body 1302 connected to each other, and the first plate body 1301 is arranged closer to the other smoke guide portion than the second plate body 1302, that is, the first plates 1301 of the two smoke guide portions are close to each other, and the second plates 1302 of the two smoke guide portions are far away from each other. The first plate 1301 and the second plate 1302 are connected in a smooth transition, that is, the connection between the first plate 1301 and the second plate 1302 is in an arc shape, and the connection between the second plate 1302 and the first plate 1301 is in a smooth transition shape on the side away from the smoke inlet 120. When the oil smoke rises and attaches to and splits at the connection between the first plate 1301 and the second plate 1302, the first plate 1301 and the second plate 1302 connected in a smooth transition will not hinder the flow of the oil smoke. At this time, a part of the oil smoke can flow along the first plate 1301, that is, along the inner side to the smoke inlet 120, and a part of the oil smoke can also flow along The second plate 1302, that is, flows along the outside toward the smoke inlet 120. The smoke guiding surface 130a of the smoke guide plate 130 formed by the first plate 1301 and the second plate 1302 can be streamlined. The first plate 1301 can well guide the oil smoke on the inner side of the center of the stove, and the second plate 1302 can well guide the oil smoke on the outer side of the center of the stove. The coordinated guiding effect of the first plate 1301 and the second plate 1302 can make the oil smoke achieve a good wall-attaching effect in multiple directions, minimize the resistance encountered by the oil smoke during the flow process, shorten the smoke residence time, and make it more unobstructed, thereby achieving effective smoke guiding.

[0082] Furthermore, if Figure 6 As shown, the first plate 1301 includes a first smoke guiding surface 131a away from the smoke inlet 120, and the second plate 1302 includes a second smoke guiding surface 132a away from the smoke inlet 120. The first smoke guiding surface 131a and / or the second smoke guiding surface 132a include curved surface segments.

[0083] Furthermore, the first plate body 1301 includes a free end and a connecting end connected to the second plate body 1302 , and the distance between the free end of the first plate body 1301 and the plane where the smoke inlet 120 is located is smaller than the distance between the connecting end and the plane where the smoke inlet 120 is located.

[0084] In this embodiment, the first plate body 1301 includes a free end and a connecting end, and the free end of the first plate body 1301 is close to the center of the smoke inlet 120. The connecting end of the first plate body 1301 is connected to the second plate body 1302. The distance between the free end of the first plate body 1301 and the plane where the smoke inlet 120 is located is less than the distance between the connecting end and the plane where the smoke inlet 120 is located, that is, the first plate body 1301 is inclined relative to the plane where the smoke inlet 120 is located. Further, along the direction from the connecting end of the first plate body 1301 to the free end of the first plate body 1301, the distance between the first smoke guide surface 131a of the first plate body 1301 and the plane where the smoke inlet 120 is located gradually decreases. Further, the first smoke guide surface 131a is curved. Specifically, when the oil smoke rises to the smoke guide plate 130, the oil smoke can flow along the inclined first plate body 1301 to the smoke inlet 120, reducing the resistance of the oil smoke flow and guiding the oil smoke so that it can smoothly condense on the wall.

[0085] Furthermore, if Figure 1 and Figure 3 As shown, the length of the first plate body 1301 is greater than or equal to the length of the second plate body 1302 .

[0086] In this embodiment, in the left-right direction, the length of the first plate 1301 is greater than the length of the second plate 1302, and in the front-back direction, the length of the first plate 1301 is equal to the length of the second plate 1302. This is because the first plate 1301 is arranged closer to the smoke inlet 120 relative to the second plate 1302, and the fan 160 of the range hood 100 can form a large negative pressure at the smoke inlet 120, which can strongly attract the oil smoke, making the length of the first plate 1301 greater than the second plate 1302, so that most of the oil smoke can be guided to the smoke inlet 120 through the first plate 1301. Since the second plate 1302 is slightly far from the smoke inlet 120 and the negative pressure there is smaller, the length of the second plate 1302 is correspondingly smaller so that a small part of the oil smoke can be guided along the second plate 1302 on the outer side. By forming a streamlined smoke guide plate 130 with different lengths of the first plate 1301 and the second plate 1302, the oil smoke that deviates from the center of the smoke source can be guided, which is more adapted to the rising characteristics of the smoke source.

[0087] Furthermore, if Figure 6 and Fig. 9 As shown, the smoke guide portion further includes a third plate body 1303 , and the third plate body 1303 is connected to the front end of the first plate body 1301 and / or the second plate body 1302 .

[0088] In this embodiment, the smoke guide part also includes a third plate 1303, the third plate 1303 is connected to the front end of the first plate 1301, and / or the third plate 1303 is connected to the front end of the second plate 1302, and the third plate 1303 is used to guide the oil smoke on the front side, so that the oil smoke on the front side can flow to the smoke inlet 120 more smoothly through the guidance of the third plate 1303. It is worth noting that the third plate 1303 includes a third smoke guide surface 130a away from the smoke inlet 120, and the third smoke guide surface 130a is a plane and / or a curved surface. It is worth noting that the front end of the first plate 1301 and / or the second plate 1302 refers to the end close to the user. When the installation position of the range hood 100 is determined, the direction of the first plate 1301 and the second plate 1302 facing the user is the front.

[0089] Furthermore, if Figure 6 As shown, the free end of the second plate body 1302 extends toward the direction close to the smoke inlet 120 .

[0090] In this embodiment, the second plate body 1302 includes a free end and a connecting end, and the connecting end of the second plate body 1302 is connected to the connecting end of the first plate body 1301. The free end of the second plate body 1302 is bent / bent and extended toward the direction close to the smoke inlet 120, so as to better guide the oil smoke biased to the outside to the oil inlet. The second plate body 1302 is curved, and the distance between the free end of the second plate body 1302 and the plane where the smoke inlet 120 is located is smaller than the distance between the connecting end of the first plate body 1301 and the plane where the smoke inlet 120 is located. Specifically, the longitudinal sections of the first plate body 1301 and the second plate body 1302 are U-shaped.

[0091] Furthermore, if Figure 6 As shown, the free end of the third plate body 1303 extends toward the direction close to the smoke inlet 120 .

[0092] In this embodiment, the third plate 1303 includes a connection end and a free end. The connection end of the third plate 1303 is connected to the first plate 1301 and / or the second plate 1302. The free end of the third plate 1303 is bent / curved and extends toward the direction close to the smoke inlet 120, so as to better guide the oil smoke biased to the front side to the oil inlet. The third plate 1303 is curved.

[0093] Specifically, the smoke guide formed by the first plate 1301, the second plate 1302 and the third plate 1303 is in the shape of a water droplet, with a smooth surface, and the resistance encountered by the oil smoke during the movement is minimal. Specifically, the smoke guide formed by the first plate 1301, the second plate 1302 and the third plate 1303 protrudes in the direction away from the smoke inlet 120 to form an arc-shaped smoke guide surface 130a, so that the oil smoke that is biased to the outside, the inside and the front can be better guided. Since the smoke guide has a streamlined curved structure, the oil smoke that is biased to the outside from the center of the smoke source will pass through the wall of the second plate 1302 and then flow to the smoke inlet 120. From the center of the smoke source, part of the oil smoke on the inner side will pass through the first plate body 1301 attached to the wall, and then flow to the smoke inlet 120. From the center of the smoke source, part of the oil smoke on the outer side will pass through the third plate body 1303 attached to the wall, flow toward the smoke inlet 120, and finally enter the interior of the smoke hood 110 through the smoke inlet 120.

[0094] Furthermore, if Figure 8 and Fig. 9 As shown, the smoke guiding portion forms a receiving cavity 1304 , and at least a portion of the receiving cavity 1304 corresponds to the smoke inlet 120 .

[0095] In this embodiment, since the free ends of the second plate body 1302 and the third plate body 1303 are bent or extended toward the direction of the smoke inlet 120, the smoke guide plate 130 composed of the first plate body 1301, the second plate body 1302 and the third plate body 1303 can form a accommodating cavity 1304 with an opening toward the smoke inlet 120. During the flow of oil smoke, since the oil will move downward due to gravity, part of the oil can fall into the accommodating cavity 1304 formed by the smoke guide part, that is, the accommodating cavity 1304 formed by the smoke guide part itself, can, to a certain extent, play a role in collecting oil, thereby solving the problem that the oil falls directly on the stove and is difficult to clean, or the problem that the oil cannot be collected when the smoke guide part is in the shape of a flat plate.

[0096] Further, the first plate body 1301 includes a flat plate and / or a curved plate. The second plate body 1302 includes a flat plate and / or a curved plate. The third plate body 1303 includes a flat plate and / or a curved plate.

[0097] In this embodiment, the first plate body 1301 includes a flat plate and / or an arc-shaped plate, that is, the first smoke guiding surface 131a of the first plate body 1301 facing away from the smoke inlet 120 is in the shape of a curved surface, or a combination of a flat surface and a curved surface, or a flat surface. Similarly, the second plate body 1302 and the third plate body 1303 can also be a flat plate and / or an arc-shaped plate, and the structures of the first plate body 1301, the second plate body 1302 and the third plate body 1303 are diversified, so that the smoke guiding surface 130a of the smoke guiding plate 130 can be a variety of guide paths.

[0098] Furthermore, the smoke guide portion is an integrated structure.

[0099] In this embodiment, the smoke guide part is an integrated structure, that is, the first plate 1301, the second plate 1302 and the third plate 1303 are an integrated structure. Because the integrated structure has good mechanical properties, it can improve the connection strength between the first plate 1301, the second plate 1302 and the third plate 1303. In addition, the first plate 1301, the second plate 1302 and the third plate 1303 can be made into one piece and mass-produced to improve the processing efficiency of the product and reduce the processing cost of the product. In addition, by designing the first plate 1301, the second plate 1302 and the third plate 1303 as an integrated structure, the integrity of the smoke guide part is improved, the number of parts is reduced, the installation process is reduced, the installation efficiency is improved, and the installation of the smoke guide part is more convenient and reliable.

[0100] Embodiment 2

[0101] According to an embodiment of the present application, a range hood 100 is provided, which adopts the range hood 100 of any of the above embodiments.

[0102] Further, based on any of the above embodiments, Figure 2 As shown, the range hood 100 of this embodiment further includes at least one connecting frame 140 . The at least one connecting frame 140 is disposed between the hood 110 and the smoke guide portion. A first gap 113 is defined between the smoke guide portion and the hood 110 .

[0103] In this embodiment, the range hood 100 further includes at least one connecting frame 140, which is disposed between the hood 110 and the smoke guide portion, that is, for each smoke guide portion, there is at least one connecting frame 140 connecting it to the hood 110. Under the action of the at least one connecting frame 140, a first gap 113 is provided between the hood 110 and the smoke guide portion, and the first gap 113 can guide the oil smoke on the outer side and the oil smoke on the front side to the smoke inlet 120 via the second plate body 1302 and the third plate body 1303.

[0104] It is worth noting that, for each smoke guide portion, there are two connecting frames 140 , and the two connecting frames 140 are arranged at intervals, thereby providing more stable support for the smoke guide portion.

[0105] Furthermore, the smoke guide portion is detachably connected to at least one connecting frame 140 .

[0106] In this embodiment, the smoke guide part is detachably connected to at least one connecting frame 140, that is, the smoke guide part and the connecting frame 140 are both detachably connected, so that the user can easily separate the smoke guide part from the smoke hood 110 and clean the independent smoke guide part, thereby reducing the difficulty of cleaning the smoke guide part. Since the smoke guide part has the function of collecting oil, a lot of oil will accumulate in the accommodating cavity 1304 formed by the smoke guide part under long-term use, and it will be necessary to clean the oil in the smoke guide part.

[0107] Furthermore, at least one connecting frame 140 is rotatably connected to the smoke hood 110 and / or the smoke guide portion.

[0108] In this embodiment, at least one connecting frame 140 is rotatably connected to the smoke hood 110. And / or at least one connecting frame 140 is rotatably connected to the smoke guide portion. In other words, at least one of the two ends of each connecting frame 140 is rotatably connected, so that the angle of the smoke guide portion relative to the smoke hood 110 can be easily adjusted to adapt to different smoke guiding requirements. When the position of the smoke source changes, the smoke guide portion can be rotated to adjust the guide angle of the smoke guide portion. Specifically, both ends of the connecting frame 140 are rotatably connected to the smoke hood 110 and the smoke guide portion, one end of the connecting frame 140 is rotatably connected to the smoke hood 110 or the smoke guide portion, and the other end of the connecting frame 140 is fixedly connected to the smoke guide portion or the smoke hood 110.

[0109] Specifically, the range hood 100 includes a hood 110, a smoke inlet 120 and at least two smoke guides, wherein the smoke inlet 120 is provided on the hood 110. At least two smoke guides are provided on the hood 110, at least a portion of each smoke guide corresponds to the smoke inlet 120, the smoke guide includes a first end and a second end opposite to each other, the first ends of at least two smoke guides are close to each other, the smoke guide includes a smoke guide surface 130a away from the smoke inlet 120, and the smoke guide surface 130a includes at least one curved surface segment between the first end and the second end.

[0110] The range hood 100 provided by the present invention includes a hood 110, a smoke inlet 120 and at least two smoke guides. The hood 110 is a hollow structure, and the oil smoke can enter the interior of the hood 110 through the smoke inlet 120 on the hood 110 to be discharged to the outside. It is worth noting that the smoke inlet 120 is arranged on the side of the hood 110 close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood 110 through the smoke inlet 120, solving the problem of the long flow path of the oil smoke and the long residence time of the oil smoke. The range hood 100 also includes at least two smoke guides, at least two smoke guides are arranged on the hood 110, and at least a part of each smoke guide is arranged corresponding to the smoke inlet 120, so that the oil smoke can move more smoothly towards the smoke inlet 120 under the guidance of the smoke guide, and finally enter the hood 110. Further, the smoke guide portion includes a first end and a second end facing each other, wherein the first ends of at least two smoke guide portions are close to each other, that is, the first end of the smoke guide portion is an inner end, the second end of the smoke guide portion is an outer end, and the first end is arranged closer to the smoke inlet 120 than the second end. It is worth noting that when the number of smoke guide portions is two, the two smoke guide portions are arranged side by side on the smoke hood 110 in the left and right directions. Since in the related art, the number of stoves is two, and the two stoves are arranged in the left and right directions. The two smoke guide portions arranged in the left and right directions can well guide the smoke source from the left and right directions. Furthermore, the smoke guiding portion includes a smoke guiding surface 130a facing away from the smoke inlet 120, and the smoke guiding surface 130a includes at least one curved surface segment between the first end and the second end, that is, the smoke guiding surface 130a includes at least one curved surface segment in the left and right directions. At this time, the oil smoke generated by the smoke sources in the left and right directions can flow along the smoke guiding surface 130a including at least one curved surface segment, and the curved surface segment can better guide the oil smoke to the smoke inlet 120. The smoke guiding portion can better adapt to the direction of rising oil smoke, making the flow of oil smoke smoother, avoiding adverse interference with the flow of oil smoke, shortening the residence time of oil smoke, and achieving the effect of limited smoke guiding. On the other hand, it can also solve the problem that the smoke guiding portion has a large interference with the flow of smoke source and a large noise.

[0111] Embodiment 3

[0112] According to an embodiment of the present application, a range hood 100 is provided, which adopts the range hood 100 of any of the above embodiments.

[0113] Further, based on any of the above embodiments, Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, there is a second gap 114 between the two smoke guides, and the second gap 114 is connected to the smoke inlet 120.

[0114] In this embodiment, there is a second interval 114 between the first ends of the two smoke guides, that is, the two smoke guides are arranged in parallel on the smoke hood 110 in the left and right directions. Specifically, the parallel structure of the double smoke guides can solve the problem that the posture of the smoke guide is inconsistent with the flow direction of the oil smoke on the left and right sides, which easily leads to large interference with the flow of oil smoke, long residence time of oil smoke, long path, easy smoke leakage, etc. Further, the second interval 114 is connected to the smoke inlet 120, and the oil smoke biased to the inside can enter the smoke inlet 120 through the second interval 114 under the guidance of the smoke guide. By setting the second interval 114, an oil smoke channel is formed, and the width of the second interval 114 can be designed according to the actual smoke guide needs. Since the negative pressure formed by the fan 160 is large at the position close to the smoke inlet 120, the oil smoke can be concentrated to flow toward the center by setting the second interval 114, and quickly enter the inside of the smoke hood 110 through the second interval 114 and the smoke inlet 120.

[0115] Furthermore, by providing a second interval 114 between the two smoke guides, it is possible to avoid the problem that a single smoke guide causes the oil smoke to adhere to the wall for too long, causing the oil smoke generated by multiple smoke sources to collide and escape in the middle area of ​​the smoke guide.

At least a portion of the oil baffle 150 is arranged corresponding to the second interval 114. The oil baffle 150 is used for blocking oil and guiding smoke. The position of the oil baffle 150 can be set to adjust the smoke intake at the second interval 114, that is, between the two smoke guide parts, thereby avoiding the problem of too much or too little smoke intake at the second interval 114, which is beneficial to reduce the blockage of oil smoke entering the hood 110, thereby improving the oil fume emission efficiency.

[0120] Furthermore, the oil blocking member 150 includes a bottom plate 151 and two smoke guide plates, and the bottom plate 151 is connected to the smoke hood 110. The two smoke guide plates are respectively arranged on both sides of the bottom plate 151, and the free ends of the smoke guide plates extend close to the smoke guide portion. The bottom plate 151 and the two smoke guide plates form an oil containing cavity 154.

[0121] In this embodiment, the oil baffle 150 includes a bottom plate 151 and two smoke guide plates. The bottom plate 151 is connected to the smoke hood 110. The bottom plate 151 has two opposite sides in the width direction. It is worth noting that the width direction is the left and right direction. The two smoke guide plates are respectively arranged on the left and right sides of the bottom plate 151, and one smoke guide plate extends toward a smoke guide portion close to it. Specifically, the two smoke guide portions include a first smoke guide portion and a second smoke guide portion, and the two smoke guide plates corresponding to the two smoke guide portions include a first smoke guide plate 152 and a second smoke guide plate 153. The first smoke guide plate 152 extends close to the first smoke guide portion, and the second smoke guide plate 153 extends close to the second smoke guide portion. In this way, the bottom plate 151, the first smoke guide plate 152 and the second smoke guide plate 153 jointly enclose an oil containing cavity 154. That is to say, the oil baffle 150 defined by the bottom plate 151 and the two smoke inlet plates has a U-shaped cross-section, so that the oil containing cavity 154 is an open groove-like structure, and the opening of the oil containing cavity 154 faces the direction of the smoke inlet 120. During the operation of the range hood 100, condensed oil can fall into the oil containing cavity 154 for collection.

[0122] Furthermore, an oil cup is provided at the bottom of the smoke hood 110 . The oil cup is a long groove-shaped structure and is located at the bottom of the two smoke guides and the oil baffle 150 , so that the oil cup can collect the oil entering from the oil chamber 154 .

[0123] Specifically, the range hood 100 includes a hood 110, a smoke inlet 120 and at least two smoke guides, wherein the smoke inlet 120 is provided on the hood 110.

The hood 110 is a hollow structure, and the oil smoke can enter the interior of the hood 110 through the smoke inlet 120 on the hood 110 to be discharged to the outside. It is worth noting that the smoke inlet 120 is arranged on the side of the hood 110 close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood 110 through the smoke inlet 120, solving the problem of the long flow path of the oil smoke and the long residence time of the oil smoke. The range hood 100 also includes at least two smoke guides, at least two smoke guides are arranged on the hood 110, and at least a part of each smoke guide is arranged corresponding to the smoke inlet 120, so that the oil smoke can move more smoothly towards the smoke inlet 120 under the guidance of the smoke guide, and finally enter the hood 110. Further, the smoke guide portion includes a first end and a second end facing each other, wherein the first ends of at least two smoke guide portions are close to each other, that is, the first end of the smoke guide portion is an inner end, the second end of the smoke guide portion is an outer end, and the first end is arranged closer to the smoke inlet 120 than the second end. It is worth noting that when the number of smoke guide portions is two, the two smoke guide portions are arranged side by side on the smoke hood 110 in the left and right directions.

The smoke guiding portion can better adapt to the direction of rising oil smoke, making the flow of oil smoke smoother, avoiding adverse interference with the flow of oil smoke, shortening the residence time of oil smoke, and achieving the effect of limited smoke guiding. On the other hand, it can also solve the problem that the smoke guiding portion has a large interference with the flow of smoke source and a large noise.

[0125] Embodiment 5

[0126] According to an embodiment of the present application, a range hood 100 is provided, which adopts the range hood 100 of any of the above embodiments.

[0127] Further, based on any of the above embodiments, in this embodiment, further, as Figure 2 As shown, the inner wall of the smoke hood 110 forms a smoke exhaust channel 111, and a part of the outer wall of the smoke hood 110 forms a smoke guiding cavity 112. The smoke guiding cavity 112 is connected to the smoke exhaust channel 111 through the smoke inlet 120. The smoke guiding part is connected to the outer wall of the smoke hood 110 and is located in the smoke guiding cavity 112, wherein the smoke guiding cavity 112 is tapered from the opening of the smoke guiding cavity 112 to the smoke inlet 120.

[0128] In this embodiment, the inner wall of the smoke hood 110 forms a smoke exhaust passage 111, and a part of the outer wall of the smoke hood 110 forms a smoke guide cavity 112, which is connected to the smoke exhaust passage 111 through the smoke inlet 120.

From the opening of the smoke guide cavity 112 to the smoke inlet 120, that is, in the direction from bottom to top, the smoke guide cavity 112 is gradually contracted, that is, the smoke guide cavity 112 is in the shape of a reverse funnel, so that the oil smoke can be easily gathered from the surroundings to the smoke inlet 120 in the middle.

[0129] Furthermore, the range hood 100 further includes a fan 160 , which is disposed in the smoke exhaust passage 111 . The fan 160 can guide the airflow to enter the smoke exhaust passage 111 through the smoke guide portion and the smoke inlet 120 .

[0130] In this embodiment, the fan 160 is disposed in the smoke hood 110, and the fan 160 and the smoke guide are respectively located on both sides of the plane where the smoke inlet 120 is located. The fan 160 can disturb the airflow, thereby guiding the oil smoke at the smoke source to enter the smoke hood 110 through the first interval 113, the second interval 114, and the smoke inlet 120 through the smoke guide. Specifically, the smoke hood 110 includes a hood body and a machine body, and the machine body and the hood body are similar to a T-shape. The fan 160 is disposed in the machine body, a part of the outer wall of the hood body forms a smoke guide cavity 112, and the smoke guide part is disposed on the hood body.

[0131] It is worth noting that the rotation axis of the fan 160 is parallel to the wall on which the range hood 100 is installed.

[0132] Furthermore, the range hood 100 further includes an oil filter 170 , which is disposed on the hood 110 and located at the smoke inlet 120 .

[0133] In this embodiment, the oil filter 170 is arranged on the smoke hood 110. When the oil smoke passes through the smoke inlet 120, it can be filtered by the oil filter 170, so that the oil adheres to the oil filter 170. After part of the oil smoke condenses, it may fall due to gravity, and the oil can pass through the second partition 114 and fall into the oil baffle 150.

[0134] It is worth noting that the oil filter 170 is installed at the smoke inlet 120, and a first smoke guide plate 131 and a second smoke guide plate 132 are provided below the oil filter 170. The first smoke guide plate 131 and the second smoke guide plate 132 are arranged in parallel on the left and right sides, and the two smoke guide plates 130 and the oil filter 170 form a series structure in the vertical direction, that is, the oil smoke first passes through the two smoke guide plates 130, and then flows through the oil filter 170. The two smoke guide plates 130 can form a streamlined curved structure, thereby realizing the reasonable guidance of the oil smoke.

[0135] Embodiment 6

[0136] According to an embodiment of the present application, a range hood 100 is provided, which adopts the range hood 100 of any of the above embodiments.

[0137] Further, based on any of the above embodiments, in this embodiment, a smoke outlet is provided on the smoke guide portion, and the smoke outlet is connected to the smoke inlet 120 , so that the oil smoke can flow from the smoke outlet into the smoke inlet 120 and finally into the interior of the smoke hood 110 .

[0138] Furthermore, the smoke guide part specifically includes a base plate and a mounting plate, the mounting plate is arranged on a side of the base plate close to the smoke inlet 120, and there is a gap between the mounting plate and the base plate. The smoke outlet includes a first opening and a second opening, the first opening is arranged on the base plate, and the second opening is arranged on the mounting plate, and the first opening and the second opening are staggered. Under the premise of not affecting the flow of oil smoke, the mounting plate and the base plate can effectively receive condensed oil, thereby preventing the oil from falling from the smoke outlet.

[0139] Furthermore, the range hood 100 also includes a folded edge, which is connected to one side of the smoke guide part close to the smoke inlet 120, and the folded edge is located at the outer edge of the smoke outlet. The folded edge and the base plate, as well as the folded edge and the mounting plate, can form an oil guide groove, which can collect condensed oil droplets. At the same time, the folded edge can also prevent oil droplets from splashing when they fall and possibly falling from the smoke outlet.

[0140] Furthermore, the smoke outlet extends from the center of the smoke guide portion toward the outer edge of the smoke guide portion, that is, the extension direction of the smoke outlet adapts to the flow direction of the oil smoke, so that during the flow of the oil smoke, it flows through the smoke outlet toward the smoke inlet 120 as much as possible.

[0141] Embodiment 7

[0142] According to an embodiment of the present application, a range hood 100 is provided, which adopts the range hood 100 of any of the above embodiments.

[0143] Further, based on any of the above embodiments, a portion of the oil baffle 150 in this embodiment extends into the second spacer 114, so that at the second spacer 114, the oil baffle 150 can also play a similar role as the smoke guide plate 130, so that the oil smoke can attach to the wall of the oil baffle 150, and be sucked to the oil filter 170 from the position between the oil baffle 150 and the first smoke guide plate 131 or the second smoke guide plate 132, and finally be discharged. Specifically, the setting of the second spacer 114 generates a large negative pressure between the first smoke guide plate 131 and the second smoke guide plate 132, and the amount of smoke intake is increased. After the oil baffle 150 is partially extended into the second interval 114, the oil baffle 150 also plays the role of the smoke guide plate 130, that is, the oil baffle 150 causes the negative pressure area at the second interval 114 to turn from the central position between the first smoke guide plate 131 and the second smoke guide plate 132 to both sides, or in other words, the negative pressure area at the second interval 114 diffuses from the central position of the second interval 114 to the surrounding directions of the oil baffle 150, so that the oil smoke originally concentrated from the second interval 114 is discharged from between the oil baffle 150 and the first smoke guide plate 131, and between the oil baffle 150 and the second smoke guide plate 132, thereby increasing the oil fume discharge path while roughly maintaining the original path, thereby improving the problem of excessive or insufficient smoke intake at the second interval 114.

[0144] In addition, the oil baffle 150 is used to receive the oil dripping from the oil filter 170, and a portion of it extends into the second compartment 114, so as to ensure that the oil baffle 150 can reduce or prevent the condensed oil on the oil filter 170 from dripping from the second compartment 114, which is helpful to keep the environment clean and improve the convenience of using the range hood 100.

[0145] Furthermore, a portion of the oil baffle 150 extends into the second compartment 114, so that a certain gap is formed between the oil baffle 150 and the first smoke guide plate 131, and a certain gap is also formed between the oil baffle 150 and the second smoke guide plate 132. Another portion of the oil baffle 150 is still located in the first compartment 113, so that the oil baffle 150 can guide the oil smoke that enters the first compartment 113 through the second compartment 114, that is, the oil baffle 150 can play a role in guiding smoke. At the same time, the portion of the oil baffle 150 in the first compartment 113 can also block the condensed oil on the oil filter 170, which is helpful to prevent it from dripping from the second compartment 114.
