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 can form a flow channel to improve the smoke extraction efficiency and air performance. However, in actual application, under the action of the fan in the range hood, the negative pressure in the middle of the smoke guide cavity is relatively large, and most of the oil smoke will be guided by the smoke guide plate and concentrated in the middle of the smoke guide cavity. However, in order to allow the increased oil smoke to be discharged as quickly as possible, multiple smoke guide plates are often provided with intervals, but the setting of the intervals will cause the condensed oil to fall onto the stove through the intervals.

[0003] Therefore, how to obtain a range hood that can improve the falling of oil droplets after condensation and can promptly discharge a large amount of concentrated oil smoke has become a technical problem that needs to be solved urgently. 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, and a smoke outlet is arranged on the smoke guide, which is connected to the smoke inlet.

[0007] The hood provided by the present invention 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 that the oil smoke has a long flow path and a long 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 is provided with a smoke port, and the smoke port can be connected with the smoke inlet. On the one hand, the oil smoke can flow from the smoke port to the direction of the smoke inlet, that is, the setting of the smoke port can reduce the resistance of the smoke guide to the oil smoke, thereby improving the exhaust efficiency. On the other hand, the smoke guide provided with the smoke port can alleviate the condensed oil droplets falling onto the stove to a certain extent. It is worth noting that when the smoke outlet includes a plurality of small holes, a portion of the smoke guide portion between adjacent small holes will be able to form resistance to the condensed oil droplets, thereby preventing some of the oil droplets from falling.

[0008] In a possible design, further, the number of the at least two smoke guide parts is two, and the smoke outlet is arranged at the ends of the two smoke guide parts close to each other.

[0009] In this design, when there are two smoke guides, the two smoke guides are arranged side by side on the hood in the left and right directions. In the related art, there are two stoves, which are arranged in the left and right directions. The two smoke guides arranged in the left and right directions can well guide the smoke source from the left and right directions. Furthermore, the smoke outlet is arranged at the end parts where the two smoke guide parts are close to each other. If the center line of the smoke inlet is taken as the inner part, the two smoke guide parts are symmetrically distributed on both sides of the center line. Each smoke guide part includes an inner end close to the center line and an outer end away from the center line. The smoke outlet is arranged at the inner end of the smoke guide part. Since the fan of the range hood can form a large negative pressure at the smoke inlet, that is, under the guidance of the smoke guide part, most of the oil smoke will be diverted to the vicinity of the center line of the smoke inlet. At this time, the smoke outlet is arranged on the inner end of the smoke guide part close to the center line, which can effectively increase the smoke intake of the smoke guide part, so that the smoke intake of the smoke guide part matches the flow trend of the oil smoke. The setting of the smoke outlet can also reduce the system resistance at the front end of the smoke guide part, increase the air intake of the smoke guide part, improve the smoke exhaust efficiency, reduce noise, etc.

[0010] In a possible design, further, the smoke guide part 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, and a first interval is provided between the mounting plate and the base plate; the smoke outlet includes at least one first opening and at least one second opening, at least one first opening is arranged on the base plate; at least one second opening is arranged on the mounting plate, and the projections of the first opening and the second opening on the plane where the smoke inlet is located at least partially do not overlap.

[0011] In this design, the smoke guide part includes a smoke guide plate, that is, the smoke guide part is a plate-shaped structure. On the basis of achieving effective guidance of oil smoke, the weight of the range hood itself can be reduced, which is adapted to the lightweight development trend of the range hood. The smoke guide plate includes a substrate and a mounting plate. The substrate is connected to the smoke hood. The mounting plate is arranged on the side of the substrate close to the smoke inlet, that is, the mounting plate is arranged on the inner side of the substrate. There is a first interval between the mounting plate and the substrate, that is, there is a bracket between the mounting plate and the substrate, and the bracket can connect the mounting plate and the substrate to form a first interval between the two. The smoke outlet includes a first opening and a second opening. The number of the first opening and the second opening is at least one, which can be set according to actual needs. The oil smoke can flow to the smoke inlet through the first opening on the substrate, the first interval, and the second opening on the mounting plate. By setting the mounting plate and the substrate, the oil smoke can be fully in contact with the smoke guide part, which is conducive to the condensation of the oil smoke on the smoke guide part. It is worth noting that the projections of the first opening and the second opening on the plane where the smoke inlet is located do not overlap at least partially, so that a large area of ​​the smoke guide can be provided as much as possible to receive condensed oil droplets without affecting the passage of oil smoke. It is worth noting that the first opening and the second opening are staggered. Specifically, when condensed oil droplets fall from the second opening and the first interval, since the first opening and the second opening are staggered, there must be a substrate below the second opening that can receive the oil droplets, thereby preventing the oil from falling from the smoke outlet as much as possible.

[0012] In a possible design, the range hood further includes a folded edge, which is connected to a side of the smoke guide portion close to the smoke inlet, and the folded edge is located at an outer edge of the smoke outlet.

[0013] In this design, the range hood further includes a folded edge, which is connected to a side of the smoke guide portion close to the smoke inlet, and is located at the outer edge of the smoke outlet, that is, the folded edge and the smoke guide portion can form an oil guide groove, which can guide and collect condensed oil droplets. At the same time, the folded edge can also prevent the oil droplets from splashing when they fall and may fall from the smoke outlet. Specifically, the folded edge can be set at the outer edge of the first opening, and the folded edge extends toward the smoke inlet. The folded edge can also be set at the outer edge of the second opening, and the folded edge extends toward the smoke inlet.

[0014] Specifically, the folding edge, the mounting plate and the base plate are an integrated structure.

[0015] In a possible design, further, the smoke outlet extends from the center of the smoke guide portion to the outer edge of the smoke guide portion.

[0016] In this design, 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 as much as possible.

[0017] In a possible design, further, there is a second interval between the ends of the two smoke guides that are close to each other.

[0018] In this design, 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 the inner end, the second end of the smoke guide portion is the outer end, and the first end is arranged closer to the smoke inlet than the second end. There is a second interval between the first ends of the two smoke guide portions, that is, the two smoke guide portions are arranged in parallel on the smoke hood in the left and right directions. Specifically, the parallel structure of the double smoke guide portions can solve the problem that the posture of the smoke guide portion 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 the oil smoke, long path, and easy smoke leakage. Further, 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 portion. 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. That is to say, the oil smoke gathered near the smoke inlet can not only be guided through the smoke outlet, but also can be guided through the second interval between the smoke guiding parts, so as to further ensure the effective discharge of the oil smoke.

[0019] 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.

[0020] In a possible design, further, the range hood includes a connecting frame, which is arranged between the base plate and the hood, and a third interval is provided between the base plate and the hood.

[0021] In this design, the range hood further comprises at least one connecting frame, which is arranged between the hood and the base plate, that is, for each smoke guide portion, there is at least one connecting frame connecting it to the hood. Under the action of the at least one connecting frame, a third interval is provided between the hood and the base plate, and the third interval can guide the oil smoke on the outer side and the oil smoke on the front side to the smoke inlet through the smoke guide portion.

[0022] 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.

[0023] In a possible design, further, the base plate is detachably connected to the connecting frame.

[0024] In this design, the base plate is detachably connected to at least one connecting frame, that is, the base plate 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.

[0025] Furthermore, 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 portion. That is to say, at least one of the two ends of each connecting frame is rotatably connected, so that the angle of the smoke guide portion 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 portion can be rotated to adjust the guide angle of the smoke guide portion. Specifically, both ends of the connecting frame are rotatably connected to the smoke hood and the smoke guide portion, one end of the connecting frame is rotatably connected to the smoke hood or the smoke guide portion, and the other end of the connecting frame is fixedly connected to the smoke guide portion or the smoke hood.

[0026] In a possible design, further, the substrate includes a first end and a second end opposite to each other, the first ends of the two substrates are close to each other, and the distance from the first end to the plane where the smoke inlet is located is smaller than the distance from the second end to the plane where the smoke inlet is located.

[0027] In this design, the substrate is a flat plate structure, and the substrate includes a first end and a second end opposite to each other. The first ends of the two substrates are close to each other, that is, the first end of the substrate is the inner end, and the second end of the substrate is the outer end. The distance from the first end of the substrate to the plane where the smoke inlet is located is smaller than the distance from the second end of the substrate to the plane where the smoke inlet is located. In the left and right directions, from the outside to the inside, the substrate is inclined relative to the plane where the smoke inlet is located. When the oil smoke rises to the smoke guide plate, the oil smoke can flow to the smoke inlet along the inclined substrate, reducing the resistance of the oil smoke flow process, and at the same time guiding the flow, so that the oil smoke can smoothly condense on the wall.

[0028] In a possible design, further, the substrate includes a first plate body and a second plate body that are connected, the first plate body is closer to another substrate than the second plate body, and the first plate body and the second plate body are connected with a smooth transition.

[0029] In this design, the base plate includes a first plate body and a second plate body connected to each other, and the first plate body is arranged closer to another 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 with 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 is attached to and diverted 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 with 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 substrate 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.

[0030] 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.

[0031] 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.

[0032] In a possible design, further, the smoke guide portion also includes a third plate body connected to the front end of the first plate body and / or the second plate body.

[0033] 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.

[0034] In a possible design, further, the free end of the second plate body extends toward a direction close to the smoke inlet.

[0035] 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.

[0036] In a possible design, further, the free end of the third plate body extends toward a direction close to the smoke inlet.

[0037] 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.

[0038] 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.

[0039] Furthermore, 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] It is worth noting that the rotation axis of the fan is parallel to the wall on which the range hood is installed.

[0045] In a possible design, the range hood further includes an oil filter, which is arranged on the hood and located at the smoke inlet.

[0046] 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.

[0047] 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.

[0069] 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.

[0070] 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.

[0071] Refer to the following Figures 1 to 8 A range hood 100 according to some embodiments of the present invention is described.

[0072] Embodiment 1

[0073] According to a first aspect of the present invention, a range hood 100 is provided. Figures 1 to 8 As shown, it includes a smoke hood 110, a smoke inlet 120 and at least two smoke guides 130, wherein the smoke inlet 120 is provided on the smoke hood 110. At least two smoke guides 130 are provided on the smoke hood 110, and a smoke outlet 140 is provided on the smoke guide 130, and the smoke outlet 140 is communicated with the smoke inlet 120.

[0074] The hood 110 provided by the present invention 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 130, at least two smoke guides 130 are arranged on the hood 110, and at least a part of each smoke guide 130 is arranged corresponding to the smoke inlet 120, so that the oil smoke can move more smoothly toward the smoke inlet 120 under the guidance of the smoke guide 130, and finally enter the hood 110. Furthermore, the smoke guide 130 is provided with a smoke outlet 140, which can be connected to the smoke inlet 120. On the one hand, the oil smoke can flow from the smoke outlet 140 to the smoke inlet 120, that is, the setting of the smoke outlet 140 can reduce the resistance of the smoke guide 130 to the oil smoke, thereby improving the smoke exhaust efficiency. On the other hand, the smoke guide 130 provided with the smoke outlet 140 can alleviate the condensed oil droplets falling onto the stove to a certain extent. It is worth noting that when the smoke outlet 140 includes a plurality of small holes, the part of the smoke guide 130 between the adjacent small holes will be able to form resistance to the condensed oil droplets, preventing some of the oil droplets from falling.

[0075] Furthermore, if Figure 1 , Figure 5 and Figure 6 As shown, there are at least two smoke guides 130 , and the smoke outlet 140 is disposed at the ends of the two smoke guides 130 that are close to each other.

[0076] In this embodiment, when there are two smoke guides 130, the two smoke guides 130 are arranged side by side in the left-right direction on the smoke hood 110. In the related art, there are two stoves, which are arranged in the left-right direction. The two smoke guides 130 arranged in the left-right direction can well guide the smoke source from the left-right direction. Furthermore, the smoke outlet 140 is arranged at the ends of the two smoke guides 130 that are close to each other. If the center line of the smoke inlet 120 is taken as the inner side, the two smoke guides 130 are symmetrically distributed on both sides of the center line. Each smoke guide 130 includes an inner end close to the center line and an outer end away from the center line. The smoke outlet 140 is arranged at the inner end of the smoke guide 130. Since the fan of the range hood 100 can form a large negative pressure at the smoke inlet 120, that is, under the guidance of the smoke guide 130, most of the oil smoke will be diverted to the vicinity of the center line of the smoke inlet 120. At this time, if the smoke outlet 140 is arranged on the inner end of the smoke guide 130 close to the center line, the smoke intake of the smoke guide 130 can be effectively increased, so that the smoke intake of the smoke guide 130 matches the flow trend of the oil smoke. The setting of the smoke outlet 140 can also reduce the system resistance at the front end of the smoke guide 130, increase the air intake of the smoke guide 130, improve the smoke exhaust efficiency, reduce noise, etc.

[0077] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, the smoke guide portion 130 includes a base plate 131 and a mounting plate 132, the mounting plate 132 is arranged on a side of the base plate 131 close to the smoke inlet 120, and a first gap 133 is provided between the mounting plate 132 and the base plate 131; the smoke outlet 140 includes at least one first opening 141 and at least one second opening 142, at least one first opening 141 is arranged on the base plate 131; at least one second opening 142 is arranged on the mounting plate 132, and the projections of the first opening 141 and the second opening 142 on the plane where the smoke inlet 120 is located at least partially do not overlap.

[0078] In this embodiment, the smoke guide portion 130 includes a smoke guide plate, that is, the smoke guide portion 130 is a plate-shaped structure. On the basis of achieving effective smoke guidance, the weight of the range hood 100 can be reduced, which is adapted to the lightweight development trend of the range hood 100. The smoke guide plate includes a base plate 131 and a mounting plate 132. The base plate 131 is connected to the smoke hood 110. The mounting plate 132 is arranged on a side of the base plate 131 close to the smoke inlet 120, that is, the mounting plate 132 is arranged on the inner side of the base plate 131. There is a first interval 133 between the mounting plate 132 and the base plate 131. In other words, there is a bracket between the mounting plate 132 and the base plate 131. The bracket can connect the mounting plate 132 and the base plate 131 and form the first interval 133 between the two. The smoke outlet 140 includes a first opening 141 and a second opening 142. The number of the first opening 141 and the second opening 142 is at least one, which can be set according to actual needs. The oil smoke can flow to the smoke inlet 120 through the first opening 141 on the substrate 131, the first interval 133, and the second opening 142 on the mounting plate 132. By setting the mounting plate 132 and the substrate 131, the oil smoke can be fully contacted with the smoke guide 130, so as to facilitate the condensation of the oil smoke on the smoke guide 130. It is worth noting that the projections of the first opening 141 and the second opening 142 on the plane where the smoke inlet 120 is located are at least partially non-overlapping, so that a large area of ​​the smoke guide 130 can be provided as much as possible to receive the condensed oil droplets without affecting the passage of the oil smoke. It is worth noting that the first opening 141 and the second opening 142 are staggered. Specifically, when the condensed oil droplets fall from the second opening 142 and the first interval 133, since the first opening 141 and the second opening 142 are staggered, there must be a substrate 131 located below the second opening 142 that can receive the oil droplets, thereby preventing the oil from falling from the smoke outlet 140 as much as possible.

[0079] Furthermore, if Figure 4 As shown, the range hood 100 further includes a folded edge 150 , which is connected to a side of the smoke guide portion 130 close to the smoke inlet 120 , and the folded edge 150 is located at an outer edge of the smoke outlet 140 .

[0080] In this embodiment, the range hood 100 further includes a folded edge 150, which is connected to a side of the smoke guide portion 130 close to the smoke inlet 120, and is located at the outer edge of the smoke outlet 140, that is, the folded edge 150 and the smoke guide portion 130 can form an oil guide groove, which can guide and collect condensed oil droplets. At the same time, the folded edge 150 can also prevent the oil droplets from splashing when falling and possibly falling from the smoke outlet 140. Specifically, the folded edge 150 can be arranged at the outer edge of the first opening 141, and the folded edge 150 extends toward the smoke inlet 120. The folded edge 150 can also be arranged at the outer edge of the second opening 142, and the folded edge 150 extends toward the smoke inlet 120.

[0081] Specifically, the folded edge 150 and the mounting plate 132 and the base plate 131 are an integrated structure.

[0082] Furthermore, if Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the smoke outlet 140 extends from the center of the smoke guiding portion 130 to the outer edge of the smoke guiding portion 130 .

[0083] In this embodiment, the smoke outlet 140 extends from the center of the smoke guide portion 130 toward the outer edge of the smoke guide portion 130, that is, the extension direction of the smoke outlet 140 adapts to the flow direction of the oil smoke, so that during the flow of the oil smoke, it flows through the smoke outlet 140 toward the smoke inlet 120 as much as possible.

[0084] Embodiment 2

[0085] Based on the above embodiments, Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, there is a second interval 160 between the ends of the two smoke guides 130 that are close to each other.

[0086] In this embodiment, the smoke guide 130 includes a first end and a second end facing each other, wherein the first ends of at least two smoke guides 130 are close to each other, that is, the first end of the smoke guide 130 is the inner end, the second end of the smoke guide 130 is the outer end, and the first end is arranged closer to the smoke inlet 120 than the second end. There is a second interval 160 between the first ends of the two smoke guides 130, that is, the two smoke guides 130 are arranged in parallel on the smoke hood 110 in the left and right directions. Specifically, the parallel structure of the double smoke guides 130 can solve the problems that the posture of the smoke guide 130 is inconsistent with the oil smoke flow direction on the left and right sides, which easily leads to large interference with the oil smoke flow, long oil smoke residence time, long path, easy smoke leakage, etc. Furthermore, the second interval 160 is connected to the smoke inlet 120, and the oil smoke that is biased to the inside can enter the smoke inlet 120 through the second interval 160 under the guidance of the smoke guide 130. By setting the second interval 160, an oil smoke channel is formed, and the width of the second interval 160 can be designed according to the actual smoke guiding needs. Since the negative pressure formed by the fan is relatively 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 160, and quickly enter the interior of the smoke hood 110 through the second interval 160 and the smoke inlet 120. In other words, the oil smoke gathered near the smoke inlet 120 can not only be guided through the smoke outlet 140, but also can be guided through the second interval 160 between the smoke guides 130, thereby further ensuring the effective discharge of the oil smoke.

[0087] Furthermore, by providing a second spacer 160 between the two smoke guides 130 , it is possible to avoid the problem that a single smoke guide 130 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 130 .

[0088] Embodiment 3

[0089] On the basis of the above-mentioned embodiment, the range hood 100 in this embodiment further includes a connecting frame, which is arranged between the base plate 131 and the hood 110 , and a third interval is formed between the base plate 131 and the hood 110 .

[0090] In this embodiment, the range hood 100 further includes at least one connecting frame, which is disposed between the hood 110 and the base plate 131. That is, for each smoke guide portion 130, there is at least one connecting frame connecting it to the hood 110. Under the action of the at least one connecting frame, a third interval is provided between the hood 110 and the base plate 131, and the third interval can guide the oil smoke on the outer side and the oil smoke on the front side to the smoke inlet 120 via the smoke guide portion 130.

[0091] It is worth noting that, for each smoke guide portion 130 , there are two connecting frames, which are arranged at intervals, thereby providing more stable support for the smoke guide portion 130 .

[0092] Furthermore, the base plate 131 is detachably connected to the connecting frame.

[0093] In this embodiment, the base plate 131 is detachably connected to at least one connecting frame, that is, the base plate 131 and the connecting frame are both detachably connected, so that the user can conveniently separate the smoke guide portion 130 from the smoke hood 110, clean the independent smoke guide portion 130, and reduce the difficulty of cleaning the smoke guide portion 130. Since the smoke guide portion 130 has the function of collecting oil, a lot of oil will accumulate in the accommodating cavity formed by the smoke guide portion 130 under long-term use, and it will be necessary to clean the oil in the smoke guide portion 130.

[0094] Further, at least one connecting frame is rotatably connected to the smoke hood 110. And / or at least one connecting frame is rotatably connected to the smoke guide portion 130. That is to say, at least one of the two ends of each connecting frame is rotatably connected, so that the angle of the smoke guide portion 130 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 130 can be rotated to adjust the guide angle of the smoke guide portion 130. Specifically, both ends of the connecting frame are rotatably connected to the smoke hood 110 and the smoke guide portion 130, one end of the connecting frame is rotatably connected to the smoke hood 110 or the smoke guide portion 130, and the other end of the connecting frame is fixedly connected to the smoke guide portion 130 or the smoke hood 110.

[0095] Embodiment 4

[0096] Based on the above embodiments, Figure 5 As shown, in this embodiment, the substrate 131 includes a first end and a second end opposite to each other. The first ends of the two substrates 131 are close to each other, and the distance from the first end to the plane where the smoke inlet 120 is located is smaller than the distance from the second end to the plane where the smoke inlet 120 is located.

[0097] In this embodiment, the substrate 131 is a flat plate structure, and the substrate 131 includes a first end and a second end opposite to each other. The first ends of the two substrates 131 are close to each other, that is, the first end of the substrate 131 is the inner end, and the second end of the substrate 131 is the outer end. The distance from the first end of the substrate 131 to the plane where the smoke inlet 120 is located is smaller than the distance from the second end of the substrate 131 to the plane where the smoke inlet 120 is located. In the left-right direction, from the outside to the inside, the substrate 131 is inclined relative to the plane where the smoke inlet 120 is located. When the oil smoke rises to the smoke guide plate, the oil smoke can flow to the smoke inlet 120 along the inclined substrate 131, reducing the resistance of the oil smoke flow process, and guiding the flow at the same time, so that the oil smoke can smoothly condense on the wall.

[0098] Specifically, the range hood 100 includes a hood 110, a smoke inlet 120 and at least two smoke guides 130, wherein the smoke inlet 120 is provided on the hood 110. At least two smoke guides 130 are provided on the hood 110, and a smoke outlet 140 is provided on the smoke guide 130, which is connected to the smoke inlet 120.

[0099] The hood 110 provided by the present invention 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 130, at least two smoke guides 130 are arranged on the hood 110, and at least a part of each smoke guide 130 is arranged corresponding to the smoke inlet 120, so that the oil smoke can move more smoothly toward the smoke inlet 120 under the guidance of the smoke guide 130, and finally enter the hood 110. Furthermore, the smoke guide 130 is provided with a smoke outlet 140, which can be connected to the smoke inlet 120. On the one hand, the oil smoke can flow from the smoke outlet 140 to the smoke inlet 120, that is, the setting of the smoke outlet 140 can reduce the resistance of the smoke guide 130 to the oil smoke, thereby improving the smoke exhaust efficiency. On the other hand, the smoke guide 130 provided with the smoke outlet 140 can alleviate the condensed oil droplets falling onto the stove to a certain extent. It is worth noting that when the smoke outlet 140 includes a plurality of small holes, the part of the smoke guide 130 between the adjacent small holes will be able to form resistance to the condensed oil droplets, preventing some of the oil droplets from falling.

[0100] Embodiment 5

[0101] Based on the above embodiments, Figure 1 As shown, in this embodiment, the substrate 131 includes a first plate body 1311 and a second plate body 1312 connected to each other. The first plate body 1311 is closer to the other substrate 131 than the second plate body 1312. The first plate body 1311 and the second plate body 1312 are connected in a smooth transition.

[0102] In this embodiment, the substrate 131 includes a first plate body 1311 and a second plate body 1312 that are connected. The first plate body 1311 is arranged closer to the other smoke guide part 130 than the second plate body 1312. That is, the first plates 1311 of the two smoke guide parts 130 are close to each other, and the second plates 1312 of the two smoke guide parts 130 are far away from each other. The first plate 1311 and the second plate 1312 are connected in a smooth transition, that is, the connection between the first plate 1311 and the second plate 1312 is in an arc shape, and the connection between the second plate 1312 and the first plate 1311 is in a smooth transition shape on the side away from the smoke inlet 120. When the oil smoke rises, it is attached to and split at the connection between the first plate 1311 and the second plate 1312. At this time, the first plate 1311 and the second plate 1312 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 1311, that is, along the inner side to the smoke inlet 120, and a part of the oil smoke can also flow to the smoke inlet 120. The smoke guiding surface of the base plate 131 formed by the first plate 1311 and the second plate 1312 can be streamlined so that the smoke flows along the second plate 1312, that is, along the outer side toward the smoke inlet 120. The first plate 1311 can well guide the oil smoke on the inner side of the center of the stove, while the second plate 1312 can well guide the oil smoke on the outer side of the center of the stove. The coordinated guiding effect of the first plate 1311 and the second plate 1312 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, shorten the smoke residence time, and make it more unobstructed, thereby achieving effective smoke guiding.

[0103] Furthermore, the first plate body 1311 includes a free end and a connecting end connected to the second plate body 1312 , and the distance between the free end of the first plate body 1311 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.

[0104] In this embodiment, the first plate 1311 includes a free end and a connecting end, and the free end of the first plate 1311 is close to the center of the smoke inlet 120. The connecting end of the first plate 1311 is connected to the second plate 1312. The distance between the free end of the first plate 1311 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 1311 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 1311 to the free end of the first plate 1311, the distance between the first smoke guide surface of the first plate 1311 and the plane where the smoke inlet 120 is located gradually decreases. Further, 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 120 along the inclined first plate 1311, reducing the resistance in the process of oil smoke flow, and guiding at the same time, so that the oil smoke can smoothly condense on the wall.

[0105] Furthermore, the length of the first plate body 1311 is greater than or equal to the length of the second plate body 1312 .

[0106] In this embodiment, in the left-right direction, the length of the first plate 1311 is greater than the length of the second plate 1312, and in the front-back direction, the length of the first plate 1311 is equal to the length of the second plate 1312. This is because the first plate 1311 is arranged closer to the smoke inlet 120 than the second plate 1312, and the fan 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 1311 greater than the second plate 1312, so that most of the oil smoke can be guided to the smoke inlet 120 through the first plate 1311. Since the second plate 1312 is slightly far from the smoke inlet 120 and the negative pressure there is smaller, the length of the second plate 1312 is correspondingly smaller so that a small part of the oil smoke can be guided along the second plate 1312 on the outer side. By forming a streamlined smoke guide plate with different lengths of the first plate 1311 and the second plate 1312, 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.

[0107] Furthermore, the smoke guiding portion 130 also includes a third plate body 1313 connected to the front end of the first plate body 1311 and / or the second plate body 1312 .

[0108] In this embodiment, the smoke guide portion 130 further includes a third plate 1313, the third plate 1313 is connected to the front end of the first plate 1311, and / or the third plate 1313 is connected to the front end of the second plate 1312, and the third plate 1313 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 1313. It is worth noting that the third plate 1313 includes a third smoke guide surface away from the smoke inlet 120, and the third smoke guide surface is a plane and / or a curved surface. It is worth noting that the front end of the first plate 1311 and / or the second plate 1312 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 1311 and the second plate 1312 facing the user is the front.

[0109] Furthermore, the free end of the second plate body 1312 extends toward the direction close to the smoke inlet 120 .

[0110] In this embodiment, the second plate body 1312 includes a free end and a connecting end, and the connecting end of the second plate body 1312 is connected to the connecting end of the first plate body 1311. The free end of the second plate body 1312 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 1312 is curved, and the distance between the free end of the second plate body 1312 and the plane where the smoke inlet 120 is located is smaller than the distance between the connecting end of the first plate body 1311 and the plane where the smoke inlet 120 is located. Specifically, the longitudinal section of the first plate body 1311 and the second plate body 1312 is U-shaped.

[0111] Furthermore, the free end of the third plate body 1313 extends toward the direction close to the smoke inlet 120 .

[0112] In this embodiment, the third plate 1313 includes a connecting end and a free end. The connecting end of the third plate 1313 is connected to the first plate 1311 and / or the second plate 1312. The free end of the third plate 1313 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 1313 is curved.

[0113] Specifically, the smoke guide 130 formed by the first plate 1311, the second plate 1312 and the third plate 1313 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 130 formed by the first plate 1311, the second plate 1312 and the third plate 1313 protrudes in the direction away from the smoke inlet 120 to form an arc-shaped smoke guide surface, so that the oil smoke that is biased to the outside, the inside and the front can be better guided. Since the smoke guide 130 is 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 1312 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 1311 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 1313 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.

[0114] Further, the first plate body 1311 includes a flat plate and / or an arc-shaped plate. The second plate body 1312 includes a flat plate and / or an arc-shaped plate. The third plate body 1313 includes a flat plate and / or an arc-shaped plate.

[0115] In this embodiment, the first plate body 1311 includes a flat plate and / or an arc-shaped plate, that is, the first smoke-guiding surface of the first plate body 1311 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 1312 and the third plate body 1313 can also be a flat plate and / or an arc-shaped plate, and the structures of the first plate body 1311, the second plate body 1312 and the third plate body 1313 are diversified, so that the smoke-guiding surface of the smoke-guiding plate can present a variety of guide paths.

[0116] Furthermore, the smoke guiding portion 130 forms a receiving cavity, and at least a portion of the receiving cavity corresponds to the smoke inlet 120 .

[0117] In this embodiment, since the free ends of the second plate body 1312 and the third plate body 1313 are bent or extended toward the direction of the smoke inlet 120, the smoke guide plate composed of the first plate body 1311, the second plate body 1312 and the third plate body 1313 can form a accommodating cavity 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 formed by the smoke guide part 130, that is, the accommodating cavity formed by the smoke guide part 130 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 130 is in the shape of a flat plate.

[0118] Furthermore, the smoke guide 130 is an integrated structure, that is, the first plate 1311, the second plate 1312 and the third plate 1313 are an integrated structure. Because the integrated structure has good mechanical properties, it can improve the connection strength between the first plate 1311, the second plate 1312 and the third plate 1313. In addition, the first plate 1311, the second plate 1312 and the third plate 1313 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 1311, the second plate 1312 and the third plate 1313 as an integrated structure, the integrity of the smoke guide 130 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 130 is more convenient and reliable.

[0119] Specifically, the range hood 100 includes a hood 110, a smoke inlet 120 and at least two smoke guides 130, wherein the smoke inlet 120 is provided on the hood 110. At least two smoke guides 130 are provided on the hood 110, and a smoke outlet 140 is provided on the smoke guide 130, which is connected to the smoke inlet 120.

[0120] The hood 110 provided by the present invention 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 130, at least two smoke guides 130 are arranged on the hood 110, and at least a part of each smoke guide 130 is arranged corresponding to the smoke inlet 120, so that the oil smoke can move more smoothly toward the smoke inlet 120 under the guidance of the smoke guide 130, and finally enter the hood 110. Furthermore, the smoke guide 130 is provided with a smoke outlet 140, which can be connected to the smoke inlet 120. On the one hand, the oil smoke can flow from the smoke outlet 140 to the smoke inlet 120, that is, the setting of the smoke outlet 140 can reduce the resistance of the smoke guide 130 to the oil smoke, thereby improving the smoke exhaust efficiency. On the other hand, the smoke guide 130 provided with the smoke outlet 140 can alleviate the condensed oil droplets falling onto the stove to a certain extent. It is worth noting that when the smoke outlet 140 includes a plurality of small holes, the part of the smoke guide 130 between the adjacent small holes will be able to form resistance to the condensed oil droplets, preventing some of the oil droplets from falling.

[0121] Specifically, the range hood 100 provided in this embodiment can solve the problem that the smoke guide part 130 greatly interferes with the flow of smoke sources from two stoves, and has a good flow-guiding and wall-attaching effect on the oil smoke that is biased to the left and right of the center of the pot and all-round in front and back, so that the residence time of the oil smoke is shortened, the flow of the oil smoke is smoother, and effective smoke guidance is achieved. At the same time, by setting the smoke outlet 140, the obstruction of the middle structure of the smoke guide part 130 to the flow of oil smoke can be solved, and the negative pressure area in the middle can be fully utilized to increase the air intake in the middle, thereby improving the air performance of the range hood 100.

[0122] Embodiment 6

[0123] On the basis of the foregoing embodiments, in this embodiment, the inner wall of the smoke hood 110 forms a smoke exhaust channel, and a portion of the outer wall of the smoke hood 110 forms a smoke guide cavity, which is connected to the smoke exhaust channel through the smoke inlet 120, and the smoke guide portion 130 is connected to the outer wall of the smoke hood 110 and is located in the smoke guide cavity, wherein the smoke guide cavity is tapered from the opening of the smoke guide cavity to the smoke inlet 120.

[0124] In this embodiment, the inner wall of the smoke hood 110 forms a smoke exhaust passage, and a part of the outer wall of the smoke hood 110 forms a smoke guide cavity, which is connected to the smoke exhaust passage through the smoke inlet 120. The smoke guide portion 130 is connected to the outer wall of the smoke hood 110, and the smoke guide portion 130 is located in the smoke guide cavity, and the smoke guide cavity is gradually contracted from the opening of the smoke guide cavity to the smoke inlet 120, that is, in the direction from bottom to top, that is, the smoke guide cavity 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.

[0125] Furthermore, the range hood 100 further includes a fan, which is disposed in the smoke exhaust passage. The fan can guide the airflow to enter the smoke exhaust passage through the smoke guide portion 130 and the smoke inlet 120 .

[0126] In this embodiment, the fan is arranged in the smoke hood 110, and the fan and the smoke guide 130 are respectively located on both sides of the plane where the smoke inlet 120 is located. The fan can disturb the airflow, thereby guiding the oil smoke at the smoke source to enter the smoke hood 110 through the first interval 133, the second interval 160, and the smoke inlet 120 through the guide of the smoke guide 130. 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 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 130 is arranged on the hood body.

[0127] It is worth noting that the rotation axis of the fan is parallel to the wall on which the range hood 100 is installed.

[0128] Furthermore, the range hood 100 further includes an oil filter, which is disposed on the hood 110 and located at the smoke inlet 120 .

[0129] In this embodiment, the oil filter 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, 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 pass through the second partition 160 and fall into the oil baffle.

[0130] It is worth noting that the oil filter is installed at the smoke inlet 120, and a first smoke guide plate and a second smoke guide plate are provided below the oil filter. The first smoke guide plate and the second smoke guide plate, which are distributed on the left and right sides, are arranged in parallel. 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.

[0131] Furthermore, the range hood 100 further includes an oil baffle, which is disposed on the hood 110 and located on a side of the smoke guide portion 130 away from the smoke inlet 120 , and at least a portion of the oil baffle is arranged corresponding to the second spacer 160 .

[0132] In this embodiment, the range hood 100 also includes an oil baffle, which is arranged on the hood 110 and located on the side of the smoke guide portion 130 away from the smoke inlet 120. At least a portion of the oil baffle is arranged corresponding to the second interval 160. The oil baffle is used for blocking oil and guiding smoke. The position of the oil baffle can be set to adjust the smoke intake at the second interval 160, that is, between the two smoke guide portions 130, thereby avoiding the problem of too much or too little smoke intake at the second interval 160, which is beneficial to reduce the blockage of oil smoke entering the hood 110, thereby improving the oil fume emission efficiency.

[0133] Further, the oil baffle comprises a bottom plate and two smoke guide plates, and the bottom plate is connected to the smoke cover 110. 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 130. The bottom plate and the two smoke guide plates form an oil containing cavity.

[0134] In this embodiment, the oil baffle comprises a bottom plate and two smoke guide plates, the bottom plate is connected to the smoke hood 110, 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 130 close thereto. Specifically, the two smoke guide portions 130 include a first smoke guide portion 130 and a second smoke guide portion 130, and the two smoke guide plates corresponding to the two smoke guide portions 130 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 130, and the second smoke guide plate extends close to the second smoke guide portion 130. In this way, the bottom plate, the first smoke guide plate and the second smoke guide plate jointly enclose an oil containing cavity. That is to say, the oil baffle defined by the bottom plate and the two smoke inlet plates has a U-shaped cross-section, so that the oil containing chamber is an open groove-like structure, and the opening of the oil containing chamber is toward the direction of the smoke inlet 120. During the operation of the range hood 100, condensed oil can fall into the oil containing chamber for collection.

[0135] 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 130 and the oil baffle, so that the oil cup can collect the oil entering from the oil chamber.
