Description

Technical Field

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

[0002] At present, the smoke guide plates of range hoods are all tilted front and back and distributed parallel to the left and right. In the related art, a smoke guide plate is disclosed that tilts from the center to the sides, forming a middle bottom and high sides. This structure is opposite to the rising flow direction of the oil smoke, which has a large interference with the oil smoke flow path and forms a long oil smoke path. When stir-frying, the oil smoke gathers, stays, and collides, which is easy to cause scattering, condensation, or smoke leakage. In addition, the related art also discloses a lifting or rotating smoke guide plate structure, but in its working state, the smoke guide plates are still in a posture of two parallel pieces on the left and right, or one parallel and one tilted piece, and cannot achieve an effective smoke guide posture of gathering the two sides to the central area.

[0003] Therefore, the current double-plate range hood smoke guide plates all have shortcomings such as the posture of the smoke guide plates is opposite to the natural flow direction of the smoke or is not smooth, causing great interference to the flow of oil smoke, the oil smoke stays for a long time, the path is long, and it is easy for smoke to escape. The most likely situation is that the oil smoke on the left and right sides converges to the middle. Summary of the invention

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

[0005] To this end, the present invention provides a range hood.

[0006] The present invention provides a range hood, comprising: a hood; a smoke inlet, arranged on the hood; at least two smoke guides, arranged in parallel on the hood, any smoke guide having a first end and a second end opposite to each other, the first ends of at least two smoke guides being close to each other, and a distance from the first end to a plane where the smoke inlet is located being smaller than a distance from the second end to a plane where the smoke inlet is located.

[0007] The range hood provided by the present invention comprises a hood, a smoke inlet and at least two smoke guides used in conjunction with each other. The smoke inlet is arranged on the hood, and the two smoke guides are arranged in parallel on the hood and used in pairs. The hood can be provided with one or more pairs of smoke guides. Any smoke guide comprises a first end and a second end arranged opposite to each other, and the first ends of the two smoke guides used in pairs are close to each other, and the second ends of the two smoke guides used in pairs are far away from each other.

[0008] In addition, when the range hood is in operation, the smoke guide is tilted relative to the plane where the smoke inlet is located, 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. In this way, the two smoke guides used in pairs can together form a posture that is high in the middle and low on both sides, and can guide the oil smoke from both sides to the middle position, ensuring that the flow direction of the oil smoke is the same as the smoke guiding direction of the smoke guide. Therefore, the two smoke guides used in pairs in the range hood proposed by the present invention have different guiding directions for the oil smoke, so that the oil smoke flows from both sides of the hood to the middle, and finally the oil smoke on both sides converges to the middle of the hood and is discharged.

[0009] In particular, most user kitchens are currently equipped with double stoves, which means that one range hood has to solve the oil fume problem of two stoves. A certain distance needs to be left between the two stoves, which means that the oil fume generated by the two stoves is located on both sides of the hood. Therefore, the range hood proposed by the present invention cooperates with the two smoke guides used in pairs, and in particular ensures that the smoke guides are inclined relative to the plane where the smoke inlet is located, so that the oil fume on both sides of the hood is gathered in the middle of the hood under the guiding effect of the two smoke guides, and finally discharged from the hood. The flow path of the oil fume is short, and during the flow of the oil fume, the smoke guide has little interference with the oil fume, and it is not easy for the liquid in the oil fume to condense and the oil fume to escape.

[0010] Therefore, in the range hood proposed by the present invention, the posture of the two smoke guide parts used in pair is the same as the natural flow direction of the oil smoke, with less interference to the flow of the oil smoke. The residence time and path of the oil smoke are short, which can effectively ensure the air performance of the range hood.

[0011] The range hood according to the above technical solution of the present invention may also have the following additional technical features:

[0012] In the above technical solution, the smoke guiding portion includes a smoke guiding surface on a side away from the smoke inlet; from the second end to the first end, the distance between the smoke guiding surface and the plane where the smoke inlet is located gradually decreases.

[0013] In this technical solution, the smoke guide part also includes a smoke guide surface. The smoke guide surface is arranged on the side of the smoke guide part away from the smoke inlet, and when the range hood is in use, the smoke guide surface is arranged toward the side of the stove. In addition, from the second end to the first end, the distance between the smoke guide surface and the plane where the smoke inlet is located gradually decreases. Therefore, during the use of the range hood, the oil smoke generated by the stove rises and contacts the smoke guide surface, and continues to flow from the second end of the smoke guide part to the first end along the smoke guide surface driven by buoyancy and external suction, and finally converges between the two paired smoke guide parts and is discharged.

[0014] In particular, from the second end to the first end of the smoke guide part, the distance between the smoke guide surface and the plane where the smoke inlet is located gradually decreases, so that the two smoke guide surfaces used in pair form a posture with a high middle and low ends, so that the oil smoke is gathered toward the middle under the guiding effect of the two smoke guide surfaces, and at the same time it can ensure that the oil smoke has little obstruction during the flow process and can flow smoothly.

[0015] In any of the above technical solutions, the smoke guiding surface is a plane.

[0016] In this technical solution, the smoke guide surface is a plane, and the plane is inclined relative to the plane where the smoke outlet is located. Setting the smoke guide surface as a plane can simplify the structural complexity of the smoke guide part and facilitate the manufacture of the smoke guide surface. On the other hand, the two smoke guide surfaces used in pairs can form an inverted V-shape with a high middle and low sides, so that the oil smoke generated by the stoves on both sides can be gathered and discharged under the guiding effect of the two smoke guide surfaces.

[0017] In any of the above technical solutions, the smoke guide part is a smoke guide plate.

[0018] In this technical solution, the smoke guide part is a smoke guide plate. The smoke guide plate is a flat plate structure, which can effectively simplify the structure of the smoke guide part while ensuring the smoke guide effect, and facilitate the processing and manufacturing of the smoke guide part. More importantly, setting the smoke guide part as a smoke guide plate can reduce the overall thickness of the smoke guide part. While meeting the smoke guide effect, the weight of the smoke guide part can be greatly reduced. On the one hand, it can reduce the risk of the smoke guide part falling during the use of the range hood. On the other hand, when a movable smoke guide part is used, it can reduce the force required to remove other driving components or manual driving by the user.

[0019] In any of the above technical solutions, the second end of the smoke guide portion is connected to the smoke hood, and the first end of the smoke guide portion is a free end.

[0020] In this technical solution, the second end of the smoke guide is connected to the smoke hood, and the first end of the smoke guide is used as a free end, so that the smoke guide is designed to be movable. During the use of the range hood, the inclination of the smoke guide relative to the plane where the smoke inlet is located can be adjusted according to the actual use environment to further improve the adaptability of the range hood.

[0021] In any of the above technical solutions, the range hood further comprises: at least two connecting members, respectively connected to the hood and at least two smoke guides, and the smoke guides are rotatably connected to the hood via the connecting members.

[0022] In this technical solution, the range hood further includes a connecting piece, the number of which is at least two and matches the number of the smoke guide parts. The connecting piece is mounted on the smoke hood, the smoke guide part is connected to the connecting piece, and the connection between the smoke guide part and the smoke hood is ensured by the connecting piece. In addition, the smoke guide part is rotatably connected to the smoke hood through the connecting piece, so that the inclination of the smoke guide part relative to the plane where the smoke inlet is located can be adjusted, and even the smoke guide part can be adjusted to be parallel to the plane where the smoke inlet is located during use.

[0023] Specifically, when the range hood is in use, the smoke guide is in a working position, the smoke guide is inclined relative to the plane where the smoke inlet is located, and the first end of the smoke guide is closer to the plane where the smoke inlet is located than the second end, so that the two smoke guides used in pairs form a state of being high in the middle and low on both sides. When the range hood is stopped or in a standby state, the smoke guide is in a non-working position, and the smoke guide is parallel to the plane where the smoke inlet is located, which can effectively balance the switching between aesthetics and efficient operation.

[0024] Specifically, during the process of adjusting the smoke guide part, the user may adjust it manually, or a driving member may be provided on the smoke hood to drive the smoke guide part to rotate.

[0025] In any of the above technical solutions, a first interval is formed between the second end of the smoke guide part and the smoke hood, and the first interval is connected to the smoke inlet; a second interval is formed between the first ends of at least two smoke guide parts, and the second interval is connected to the smoke inlet.

[0026] In this technical solution, a first interval is formed between the second end of the smoke guide and the smoke hood, a second interval is formed between the first ends of the two smoke guides used in pair, and both the first interval and the second interval are connected to the smoke inlet. In addition, the first interval is defined by the first ends of the two smoke guides used in pair, and the first ends of the smoke guides are closer to the plane where the smoke inlet is located than the second ends, so that most of the oil smoke can be gathered to the second interval under the action of the two smoke guides used in pair, and discharged through the second interval, and only a very small amount of oil smoke passes through the first interval between the second ends of the smoke guides and the smoke hood.

[0027] In any of the above technical solutions, the range hood further comprises: an oil baffle, which is arranged on the hood, and the first end of the smoke guide portion is located between the oil baffle and the smoke inlet, and there is a gap between the first end of the smoke guide portion and the oil baffle.

[0028] In this technical solution, the range hood further includes an oil baffle. The oil baffle is arranged in the hood and is located at the position of the second interval formed by the two paired smoke guides. When the range hood is in use, the oil smoke flows to the position of the oil baffle under the action of the two paired smoke guides, and converges at the oil baffle and is discharged through the second interval. In addition, the first end of the smoke guide is located between the plane where the oil smoke and the smoke inlet are located, and a certain gap is ensured between the first end of the smoke guide and the oil baffle, so that the oil smoke can be discharged through the gap.

[0029] Specifically, the front and rear ends of the oil baffle are respectively connected to the front wall and the rear wall of the smoke hood.

[0030] In any of the above technical solutions, the oil baffle comprises: a bottom plate connected to the smoke hood; two smoke induction plates arranged on the bottom plate and respectively arranged close to the two smoke guiding parts; wherein the bottom plate and the two smoke induction plates form a accommodating chamber.

[0031] In this technical solution, the oil baffle includes a bottom plate and two smoke guide plates arranged on the bottom plate. The bottom plate is connected to the smoke hood, and the extension direction of the bottom plate is consistent with the distribution direction of the first end of the smoke guide part and the extension direction of the second interval. The two smoke guide plates are arranged on the bottom plate, located on opposite sides of the bottom plate, and are respectively arranged close to the two smoke guide parts. In this way, a accommodating chamber is constructed by the bottom plate and the two smoke guide parts, and the accommodating chamber is located below the second interval. In this way, during the use of the range hood, the oil smoke gathered from both sides to the second interval is discharged through the second interval, and a small part of the small oil droplets mixed in the oil smoke are collected in the accommodating chamber to prevent the oil smoke from condensing and dripping.

[0032] In addition, the two smoke inlet plates are used in conjunction with the two smoke guide parts that are used in pair. Since the oil smoke is gathered to the second compartment under the action of the two smoke guide parts that are used in pair, the oil smoke on both sides can be divided and guided respectively through the arrangement of the above-mentioned two smoke inlet plates, so that the oil smoke on both sides can smoothly enter the second compartment and be discharged from the second compartment, thereby preventing the oil smoke flowing from both sides from scattering and escaping due to collision, thereby improving the collection and discharge of oil smoke by the oil suction press.

[0033] In any of the above technical solutions, the first end of the smoke guiding portion extends between the two smoke guiding plates.

[0034] In this technical solution, the smoke guide portion extends from the second end to the first end, and the first end of the smoke guide portion extends between the two smoke guide plates. In this way, the smoke guide portion can directly guide the oil smoke to the top of the oil baffle. Therefore, when the range hood is in use, when the oil smoke is separated from the first end of the smoke guide portion, it can be directly above the bottom plate of the oil baffle, so that it can be directly sucked away by the negative pressure area above.

[0035] In any of the above technical solutions, the bottom plate is inclined relative to the horizontal plane, and an oil guide hole is provided at the lower end of the bottom plate; the range hood also includes an oil cup, which is located below the oil guide hole.

[0036] In this technical solution, the bottom plate is tilted relative to the horizontal plane, so that the two ends of the bottom plate are at different heights, and an oil guide hole is provided at the lower end of the bottom plate, and an oil cup is provided below the oil guide hole. In this way, the liquid collected in the accommodating chamber can flow to the location of the oil guide hole under the action of its own gravity, and drip through the oil guide hole and be collected in the oil cup. Through the cooperation of the oil guide hole and the oil cup, the liquid in the oil baffle can be effectively collected in the oil cup, while preventing the collected liquid from dripping.

[0037] More importantly, the oil cup is detachably arranged on the smoke hood, which makes the oil cup easier to disassemble than the oil baffle, and is convenient for the user to disassemble the oil cup to clean the oil stains in the oil cup.

[0038] In any of the above technical solutions, any smoke guide part has a relative third end and fourth end, and the distance from the third end to the plane where the smoke inlet is located is smaller than the distance from the fourth end to the plane where the smoke inlet is located; wherein the oil guide hole and the fourth end are located on the same side of the smoke hood.

[0039] In this technical solution, any smoke guide has a third end and a fourth end relative to each other, and when the range hood is in use, the distance from the third end to the plane where the smoke inlet is located is smaller than the distance from the fourth end to the plane where the smoke inlet is located, so that the smoke guide is tilted as a whole, so that the smoke guide is arranged toward the user side, which improves the overall aesthetics of the range hood on the one hand and ensures the smoke extraction efficiency of the range hood on the other hand. In addition, the oil guide hole and the fourth end are located on the same side of the hood, so that the oil baffle and the smoke guide are tilted in the same direction, ensuring the structural coordination of the two.

[0040] Specifically, the first end of the smoke guide part is the inner end, the second end is the side end, and the first end and the second end are distributed along the left and right direction of the range hood; the third end of the smoke guide part is the front end, and the fourth end is the rear end, and the third end and the fourth end are distributed along the front and back direction of the range hood.

[0041] In any of the above technical solutions, the smoke hood includes: a smoke exhaust channel having a smoke inlet and a smoke exhaust port connected to each other; a smoke guiding cavity connected to the smoke exhaust channel through the smoke inlet, and at least two smoke guiding parts are arranged in the smoke guiding cavity.

[0042] In this technical solution, the smoke hood includes a smoke guide cavity and a smoke exhaust channel. The smoke exhaust channel is located above the smoke guide cavity, and the smoke exhaust channel includes a smoke inlet and a smoke exhaust port that are connected. The smoke guide cavity is connected to the smoke exhaust channel through the smoke inlet, and at least two smoke guides are arranged in the smoke guide cavity and can guide the oil smoke toward the smoke exhaust channel.

[0043] Specifically, in the vertical direction, the first end of the smoke guide part is located below the smoke inlet of the smoke exhaust channel; in the horizontal direction, the second end of the smoke guide part is located on the side of the smoke inlet of the smoke exhaust channel. In this way, when the range hood is in use, the two sides of the smoke guide cavity of the two smoke guide parts used in pair guide the oil smoke toward the middle of the smoke guide cavity, and the oil smoke after the guide is gathered at the second interval formed by the two smoke guide parts, and flows to the smoke inlet through the second interval, and finally discharged through the smoke inlet.

[0044] In any of the above technical solutions, the smoke guiding cavity has an opening, the opening is communicated with the smoke inlet, and at least two smoke guiding parts are located between the opening and the smoke inlet.

[0045] In this technical solution, the smoke guide cavity has an opening, which is located below the smoke guide portion and is connected to the smoke inlet. In particular, the opening area of ​​the smoke guide cavity is larger than the area of ​​the smoke inlet of the smoke exhaust channel, so that the smoke guide hood can be arranged above the stove to initially collect the oil smoke generated by the stove.

[0046] In any of the above technical solutions, the inner wall of the smoke guiding cavity gradually shrinks from the opening to the smoke inlet.

[0047] In this technical solution, the inner wall of the smoke guide cavity is reduced from the direction of the smoke inlet of the opening, so that the smoke guide cavity itself has a certain gathering and collecting effect on the oil smoke, and the smoke guide part cooperates with the smoke guide cavity to ensure efficient smoke extraction of the range hood.

[0048] In any of the above technical solutions, the range hood also includes: a fan, arranged in the hood, the fan and at least two smoke guides are located on both sides of the smoke inlet; and / or an oil filter, arranged in the hood, the smoke filter is located at the smoke inlet, or between the smoke inlet and at least two smoke guides.

[0049] In this technical solution, the range hood further includes a fan and an oil filter. The fan is arranged in the hood, and is specifically arranged in the smoke exhaust channel. The fan is located above the smoke inlet, and at least two smoke guides are located below the smoke inlet. In this way, the operation of the fan can form a negative pressure in the smoke exhaust channel to attract the oil smoke entering the smoke guide cavity, and the oil smoke enters the smoke exhaust channel along the paired smoke guide under the action of suction.

[0050] In addition, an oil filter is also provided in the smoke hood. The oil filter can be provided at the smoke inlet, or between the smoke inlet and at least two smoke guides. In this way, the oil smoke passes through the oil filter under the drive of the fan, and the small oil droplets mixed in the oil smoke are captured by the oil filter and collected in the accommodating chamber of the oil baffle.

DETAILED DESCRIPTION

[0062] 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.

[0063] 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.

[0064] Refer to the following Figures 1 to 7 To describe the range hood provided according to some embodiments of the present invention. Figure 5 and Figure 6 The middle dotted line indicates the path through which the oil smoke flows.

[0065] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first embodiment of the present invention provides a range hood, comprising: a hood 102, a smoke inlet 104, and at least two smoke guides 106 used in conjunction with each other. The smoke inlet 104 is arranged on the hood 102, and the two smoke guides 106 are arranged in parallel on the hood 102 and used in pairs. The hood 102 can be provided with one or more pairs of smoke guides 106. Any smoke guide 106 includes a first end 108 and a second end 110 arranged opposite to each other, and the first ends 108 of the two smoke guides 106 used in pairs are close to each other, and the second ends 110 of the two smoke guides 106 used in pairs are far away from each other.

[0066] like Figure 1 As shown, in the working state of the range hood, the smoke guide portion 106 is inclined relative to the plane where the smoke inlet 104 is located, and the distance from the first end 108 to the plane where the smoke inlet 104 is located is smaller than the distance from the second end 110 to the plane where the smoke inlet 104 is located. In this way, the two smoke guide portions 106 used in pairs can together form a posture that is high in the middle and low on both sides, and can guide the oil smoke from both sides to the middle position. Therefore, the two smoke guide portions 106 used in pairs in the range hood proposed in this embodiment make the two smoke guide portions 106 have different guiding directions for the oil smoke, so that the oil smoke flows from both sides of the hood 102 to the middle, and finally makes the oil smoke on both sides converge to the middle of the hood 102 and then be discharged, and it can be ensured that the flow direction of the oil smoke on both sides matches the smoke guiding direction of the smoke guide portion 106.

[0067] In particular, most user kitchens are currently equipped with double stoves, which means that one range hood has to solve the oil fume problem of two stoves. A certain distance needs to be left between the two stoves, which means that the oil fume generated by the two stoves is located on both sides of the hood 102. Therefore, the range hood proposed in this embodiment cooperates with the two smoke guides 106 used in pairs, and in particular, ensures that the smoke guide 106 is inclined relative to the plane where the smoke inlet 104 is located, so that the oil fume on both sides of the hood 102 is gathered in the middle of the hood 102 under the guiding effect of the two smoke guides 106, and finally discharged from the hood 102. The flow path of the oil fume is short, and during the flow of the oil fume, the smoke guide 106 has little interference with the oil fume, and it is not easy for the liquid in the oil fume to condense and the oil fume to escape.

[0068] The second embodiment of the present invention provides a range hood, which is further configured based on the first embodiment. Figure 3 and Figure 4 As shown, the smoke guide portion 106 also includes a smoke guide surface 112. The smoke guide surface 112 is arranged on the side of the smoke guide portion 106 away from the smoke inlet 104, and when the range hood is in use, the smoke guide surface 112 is arranged toward the side of the stove. In addition, from the second end 110 to the first end 108, the distance between the smoke guide surface 112 and the plane where the smoke inlet 104 is located gradually decreases. Therefore, during the use of the range hood, the oil smoke generated by the stove rises and contacts the smoke guide surface 112, and continues to flow from the second end 110 of the smoke guide portion 106 to the first end 108 along the smoke guide surface 112 driven by buoyancy and external suction, and finally converges between the two paired smoke guide portions 106 and is discharged.

[0069] In particular, if Figure 3 and Figure 4 As shown, from the second end 110 to the first end 108 of the smoke guiding portion 106, the distance between the smoke guiding surface 112 and the plane where the smoke inlet 104 is located gradually decreases, so that the two smoke guiding surfaces 112 used in pair form a posture with a high middle and low ends, so that the oil smoke is gathered toward the middle under the guiding effect of the two smoke guiding surfaces 112, and at the same time, it can ensure that the oil smoke has little obstruction during the flow process and can flow smoothly.

[0070] In this embodiment, further, Figure 3 and Figure 4 As shown, the smoke guide surface 112 is a plane, and the plane is inclined relative to the plane where the smoke outlet 140 is located. Setting the smoke guide surface 112 as a plane can simplify the structural complexity of the smoke guide portion 106 and facilitate the manufacture of the smoke guide surface 112. On the other hand, the two smoke guide surfaces 112 used in pairs can form an inverted V-shape with a high middle and low sides, so that the oil smoke generated by the stoves on both sides can be gathered and discharged under the guiding effect of the two smoke guide surfaces 112.

[0071] The third embodiment of the present invention provides a range hood, which is further configured based on the first embodiment. Figure 3 and Figure 4 As shown, the smoke guide part 106 is a smoke guide plate, and the range hood specifically includes a first smoke guide plate 114a and a second smoke guide plate 114b. Among them, the first smoke guide plate 114a and the second smoke guide plate 114b are planar plate structures, which can effectively simplify the structure of the smoke guide part 106 while ensuring the smoke guide effect, and facilitate the processing and manufacturing of the smoke guide part 106. More importantly, setting the smoke guide part 106 as a smoke guide plate can reduce the overall thickness of the smoke guide part 106. While meeting the smoke guide effect, the weight of the smoke guide part 106 can be greatly reduced. On the one hand, it can reduce the risk of the smoke guide part 106 falling during the use of the range hood. On the other hand, when a movable smoke guide part 106 is used, it can reduce the force required to remove other driving components or manual driving by the user.

[0072] In this embodiment, further, Figure 1 and Figure 2 As shown, the second end 110 of the smoke guide 106 is connected to the smoke hood 102, and the first end 108 of the smoke guide 106 is used as a free end, so that the smoke guide 106 is a movable design. During the use of the range hood, the inclination of the smoke guide 106 compared to the plane where the smoke inlet 104 is located can be adjusted according to the actual use environment to further improve the adaptability of the range hood.

[0073] In this embodiment, further, Figure 1 and Figure 2 As shown, the range hood further includes a connecting piece, the number of which is at least two and matches the number of the smoke guides 106. The connecting piece is mounted on the smoke hood 102, and the smoke guide 106 is connected to the connecting piece, and the connection between the smoke guide 106 and the smoke hood 102 is ensured by the connecting piece. In addition, the smoke guide 106 is rotatably connected to the smoke hood 102 through the connecting piece, so that the inclination of the smoke guide 106 compared to the plane where the smoke inlet 104 is located can be adjusted, and even the smoke guide 106 can be adjusted to be parallel to the plane where the smoke inlet 104 is located during use.

[0074] Specifically, Figure 1 As shown, when the range hood is in use, the smoke guide 106 is in a working position, the smoke guide 106 is inclined relative to the plane where the smoke inlet 104 is located, and the first end 108 of the smoke guide 106 is closer to the plane where the smoke inlet 104 is located than the second end 110, so that the two smoke guides 106 used in pairs form a state where the middle is high and the two sides are low. Figure 2As shown, when the range hood is in shutdown or standby mode, the smoke guide portion 106 is in a non-working position, and the smoke guide portion 106 is parallel to the plane where the smoke inlet 104 is located, which can effectively take into account both aesthetics and efficient working switching.

[0075] Specifically, during the process of adjusting the smoke guide portion 106 , the user may adjust it manually, or a driving member may be provided on the smoke hood 102 , and the driving member may then drive the smoke guide portion 106 to rotate.

[0076] In a specific embodiment, Figure 1 and Figure 2 As shown, the range hood includes a first connecting member 116a and a second connecting member 116b, wherein the first smoke guide plate 114a is rotatably mounted on the hood 102 via the first connecting member 116a, and the second smoke guide plate 114b is rotatably mounted on the hood 102 via the second connecting member 116b.

[0077] The fourth embodiment of the present invention provides a range hood, which is further configured based on the first embodiment. Figure 5 , Figure 6 and Figure 7 As shown, a first interval 142 is formed between the second end 110 of the smoke guide 106 and the smoke hood 102, and a second interval 144 is formed between the first ends 108 of the two smoke guides 106 used in pairs, and the first interval 142 and the second interval 144 are both connected to the smoke inlet 104. In addition, the first interval 142 is defined by the first ends 108 of the two smoke guides 106 used in pairs, and the first ends 108 of the smoke guides 106 are closer to the plane where the smoke inlet 104 is located than the second ends 110, so that most of the oil smoke can be gathered to the second interval 144 under the action of the two smoke guides 106 used in pairs, and discharged through the second interval 144, and only a very small amount of oil smoke passes through the first interval 142 between the second ends 110 of the smoke guides 106 and the smoke hood 102.

[0078] In this embodiment, further, Figure 5 , Figure 6 and Figure 7 As shown, the range hood further includes an oil baffle 118. The oil baffle 118 is disposed in the hood 102 and is located at the position where the second interval 144 formed by the two paired smoke guides 106 is located. When the range hood is in use, the oil smoke flows to the position where the oil baffle 118 is located under the action of the two paired smoke guides 106, and converges at the oil baffle 118 and is discharged through the second interval 144. In addition, the first end 108 of the smoke guide 106 is located between the plane where the oil smoke and the smoke inlet 104 are located, and a certain gap is ensured between the first end 108 of the smoke guide 106 and the oil baffle 118, so that the oil smoke can be discharged through the gap.

[0079] Specifically, Figure 5 , Figure 6 and Figure 7 As shown, the front and rear ends of the oil retaining member 118 are connected to the front wall and the rear wall of the smoke hood 102 respectively.

[0080] In this embodiment, further, Figure 7 As shown, the oil baffle 118 includes a bottom plate 120 and two smoke guide plates 122 arranged on the bottom plate 120. The bottom plate 120 is connected to the smoke hood 102, and the extension direction of the bottom plate 120 is consistent with the distribution direction of the first end 108 of the smoke guide portion 106 and the extension direction of the second interval 144. The two smoke guide plates 122 are arranged on the bottom plate 120, located on opposite sides of the bottom plate 120, and are respectively arranged close to the two smoke guide portions 106. In this way, a receiving chamber is constructed by the bottom plate 120 and the two smoke guide portions 106, and the receiving chamber is located below the second interval 144. In this way, during the use of the range hood, the oil smoke gathered from both sides to the second interval 144 is discharged through the second interval 144, and a small part of the small oil droplets mixed in the oil smoke are collected in the receiving chamber to prevent the oil smoke from condensing and dripping.

[0081] In addition, the two smoke guide plates 122 are used in conjunction with the two paired smoke guide portions 106. Since the oil smoke is gathered to the second compartment 144 under the action of the two paired smoke guide portions 106, the two smoke guide plates 122 are arranged to divide and guide the oil smoke on both sides, respectively, so that the oil smoke on both sides can smoothly enter the second compartment 144 and be discharged from the second compartment 144, thereby preventing the oil smoke flowing from both sides from scattering and escaping due to collision, thereby improving the collection and discharge of oil smoke by the oil suction press.

[0082] In this embodiment, further, Figure 7 As shown, the smoke guide portion 106 extends from the second end 110 to the first end 108, and the first end 108 of the smoke guide portion 106 extends between the two smoke guide plates 122. In this way, the smoke guide portion 106 can guide the oil smoke directly to the top of the oil baffle 118. Therefore, when the range hood is in use, when the oil smoke is separated from the first end 108 of the smoke guide portion 106, it can be directly above the bottom plate 120 of the oil baffle 118, so that it can be directly sucked away by the negative pressure area above.

[0083] In this embodiment, further, Figure 5 , Figure 6 and Figure 7As shown, the bottom plate 120 is tilted relative to the horizontal plane, so that the two ends of the bottom plate 120 are at different heights, and an oil guide hole is provided at the lower end of the bottom plate 120, and an oil cup 124 is provided below the oil guide hole. In this way, the liquid collected in the accommodating chamber can flow to the location of the oil guide hole under the action of its own gravity, and drip through the oil guide hole and be collected in the oil cup 124. Through the cooperation of the oil guide hole and the oil cup 124, the liquid in the oil blocking member 118 can be effectively collected in the oil cup 124, while preventing the collected liquid from dripping.

[0084] More importantly, the oil cup 124 is detachably disposed on the smoke hood 102 , which makes the oil cup 124 easier to disassemble than the oil baffle 118 , making it convenient for the user to disassemble the oil cup 124 to clean the oil stains in the oil cup 124 .

[0085] In this embodiment, further, Figure 3 and Figure 4 As shown, any smoke guide 106 has a third end 126 and a fourth end 128 relative to each other, and during the use of the range hood, the distance from the third end 126 to the plane where the smoke inlet 104 is located is smaller than the distance from the fourth end 128 to the plane where the smoke inlet 104 is located, so that the smoke guide 106 is tilted as a whole, so that the smoke guide 106 is set toward the user side, which improves the overall aesthetics of the range hood on the one hand and ensures the smoke extraction efficiency of the range hood on the other hand. In addition, the oil guide hole and the fourth end 128 are located on the same side of the hood 102, so that the oil baffle 118 and the smoke guide 106 are tilted in the same direction to ensure the structural coordination of the two.

[0086] Specifically, Figure 3 and Figure 4 As shown, the first end 108 of the smoke guide portion 106 is the inner end, the second end 110 is the side end, and the first end 108 and the second end 110 are distributed along the left and right direction of the range hood; the third end 126 of the smoke guide portion 106 is the front end, and the fourth end 128 is the rear end, and the third end 126 and the fourth end 128 are distributed along the front and back direction of the range hood.

[0087] The fifth embodiment of the present invention provides a range hood, which is further configured based on the first embodiment. Figure 1 and Figure 2 As shown, the smoke hood 102 includes a smoke guiding cavity 132 and a smoke exhaust passage 130. The smoke exhaust passage 130 is located above the smoke guiding cavity 132, and the smoke exhaust passage 130 includes a smoke inlet 104 and a smoke exhaust port 140 that are connected, and the smoke guiding cavity 132 is connected to the smoke exhaust passage 130 through the smoke inlet 104, and at least two smoke guiding parts 106 are arranged in the smoke guiding cavity, and can guide the oil smoke toward the smoke exhaust passage 130.

[0088] Specifically, Figure 1 and Figure 2 As shown, in the vertical direction, the first end 108 of the smoke guide 106 is located below the smoke inlet 104 of the smoke exhaust channel 130; in the horizontal direction, the second end 110 of the smoke guide 106 is located on the side of the smoke inlet 104 of the smoke exhaust channel 130. In this way, when the range hood is in use, the two smoke guides 106 used in pairs guide the smoke toward the middle of the smoke guide cavity 132 on both sides, and the guided smoke gathers at the second interval 144 formed by the two smoke guides 106, flows to the smoke inlet 104 through the second interval 144, and is finally discharged through the smoke inlet 104.

[0089] In a specific embodiment, Figure 1 and Figure 2 As shown, the smoke guiding cavity 132 and the smoke exhaust channel 130 are an integrated structure.

[0090] In this embodiment, further, Figure 1 and Figure 2 As shown, the smoke guiding cavity 132 has an opening 134, which is located below the smoke guiding portion 106 and communicates with the smoke inlet 104. In particular, the area of ​​the opening 134 of the smoke guiding cavity 132 is larger than the area of ​​the smoke inlet 104 of the smoke exhaust channel 130, so that the smoke guiding hood 102 can be arranged above the stove to initially collect the oil smoke generated by the stove.

[0091] The sixth embodiment of the present invention provides a range hood, which is further configured based on the first embodiment. Figure 1 and Figure 2 As shown, the range hood further includes a fan 136 and an oil filter 138. The fan 136 is disposed in the hood 102, and is specifically disposed in the smoke exhaust passage 130. The fan 136 is located above the smoke inlet 104, and at least two smoke guides 106 are located below the smoke inlet 104. In this way, the operation of the fan 136 can form a negative pressure in the smoke exhaust passage 130 to attract the oil smoke entering the smoke guide cavity 132, and allow the oil smoke to enter the inside of the smoke exhaust passage 130 along the paired smoke guides 106 under the action of suction.

[0092] In addition, if Figure 1 and Figure 2 As shown, an oil filter 138 is further provided in the smoke hood 102. The oil filter 138 can be provided at the smoke inlet 104, or between the smoke inlet 104 and at least two smoke guides 106. In this way, the oil smoke passes through the oil filter 138 under the drive of the fan 136, and the small oil droplets mixed in the oil smoke are captured by the oil filter 138 and collected in the accommodating chamber of the oil blocking member 118.

[0093] Specific embodiment 1, the embodiment of the present invention provides a range hood, such as Figure 1 and Figure 2As shown, it includes: a smoke hood 102, a smoke inlet 104 and at least two smoke guides 106 used in conjunction with each other. Any smoke guide 106 includes a first end 108 and a second end 110 arranged opposite to each other, the first ends 108 of the two smoke guides 106 used in pairs are close to each other, and the second ends 110 of the two smoke guides 106 used in pairs are far away from each other.

[0094] When the range hood is in operation, the smoke guide 106 is inclined relative to the plane where the smoke inlet 104 is located, and the distance from the first end 108 to the plane where the smoke inlet 104 is located is smaller than the distance from the second end 110 to the plane where the smoke inlet 104 is located, so that the smoke on both sides of the hood 102 is gathered in the middle of the hood 102 under the guiding effect of the two smoke guides 106, and finally discharged from the hood 102. The flow path of the smoke is short, and during the flow of the smoke, the smoke guide 106 has little interference with the smoke, and it is not easy for the liquid in the smoke to condense and the smoke to escape.

[0095] In this embodiment, further, Figure 3 and Figure 4 As shown, the smoke guide portion 106 also includes a smoke guide surface 112, which is arranged on the side of the smoke guide portion 106 away from the smoke inlet 104. The oil smoke generated by the stove rises and contacts the smoke guide surface 112, and continues to flow from the second end 110 of the smoke guide portion 106 to the first end 108 along the smoke guide surface 112 under the drive of buoyancy and external suction, and finally converges between the two paired smoke guide portions 106 and is discharged.

[0096] In this embodiment, further, Figure 3 and Figure 4 As shown, the smoke guiding surface 112 is a plane, and the smoke guiding portion 106 is a smoke guiding plate, which specifically includes a first smoke guiding plate 114a and a second smoke guiding plate 114b.

[0097] In this embodiment, further, Figure 3 and Figure 4 As shown, the second end 110 of the smoke guide portion 106 is connected to the smoke cover 102, and the first end 108 of the smoke guide portion 106 is used as a free end.

[0098] In this embodiment, further, Figure 1 and Figure 2 As shown, the range hood also includes a connecting piece, and the smoke guide part 106 is rotatably connected to the hood 102 through the connecting piece, so that the inclination degree of the smoke guide part 106 compared to the plane where the smoke inlet 104 is located can be adjusted, and the smoke guide part 106 can even be adjusted to be parallel to the plane where the smoke inlet 104 is located during use.

[0099] Specifically, Figure 1As shown, when the range hood is in use, the smoke guide portion 106 is in a working posture, the smoke guide portion 106 is inclined compared to the plane where the smoke inlet 104 is located, and the first end 108 of the smoke guide portion 106 is ensured to be closer to the plane where the smoke inlet 104 is located than the second end 110, so that the two smoke guide portions 106 used in pair form a state with a higher middle and lower sides.

[0100] like Figure 2 As shown, when the range hood is in shutdown or standby mode, the smoke guide portion 106 is in a non-working position, and the smoke guide portion 106 is parallel to the plane where the smoke inlet 104 is located, which can effectively take into account both aesthetics and efficient working switching.

The oil baffle 118 is disposed in the hood 102 and is located at the position of the second interval 144 formed by the two paired smoke guides 106. When the range hood is used, the oil smoke flows to the position of the oil baffle 118 under the action of the two paired smoke guides 106, and converges at the oil baffle 118 and is discharged through the second interval 144.

[0103] In this embodiment, the oil baffle 118 further includes a bottom plate 120 and two smoke guide plates 122 disposed on the bottom plate 120. The bottom plate 120 and the two smoke guides 106 together form a receiving chamber, and the first end 108 of the smoke guide 106 extends between the two smoke guide plates 122. In this way, when the range hood is in use, when the oil smoke is separated from the first end 108 of the smoke guide 106, it can be directly above the bottom plate 120 of the oil baffle 118 and can be directly sucked away by the negative pressure area above.

[0104] In this embodiment, the bottom plate 120 is further inclined relative to the horizontal plane, so that the two ends of the bottom plate 120 are at different heights, and an oil guide hole is provided at the lower end of the bottom plate 120, and an oil cup 124 is provided below the oil guide hole.

[0105] In this embodiment, further, any smoke guide portion 106 has a relative third end 126 and a fourth end 128, and during the use of the range hood, the distance from the third end 126 to the plane where the smoke inlet 104 is located is smaller than the distance from the fourth end 128 to the plane where the smoke inlet 104 is located, so that the smoke guide portion 106 is tilted as a whole.

[0106] Specifically, the first end 108 of the smoke guide portion 106 is the inner end, the second end 110 is the side end, and the first end 108 and the second end 110 are distributed along the left and right direction of the range hood; the third end 126 of the smoke guide portion 106 is the front end, and the fourth end 128 is the rear end, and the third end 126 and the fourth end 128 are distributed along the front and back direction of the range hood.

[0107] In this embodiment, the smoke hood 102 further includes a smoke guiding cavity 132 and a smoke exhaust passage 130. The smoke exhaust passage 130 is located above the smoke guiding cavity 132, and the smoke exhaust passage 130 includes a smoke inlet 104 and a smoke exhaust port 140 that are connected, and the smoke guiding cavity 132 is connected to the smoke exhaust passage 130 through the smoke inlet 104, and at least two smoke guiding parts 106 are arranged in the smoke guiding cavity 132, and can guide the oil smoke toward the smoke exhaust passage 130.

[0108] In this embodiment, further, the smoke guiding cavity 132 has an opening 134 , which is located below the smoke guiding portion 106 and communicates with the smoke inlet 104 , and the inner wall of the smoke guiding cavity 132 tapers from the opening 134 to the smoke inlet 104 .

[0109] In this embodiment, the range hood further includes a fan 136 and an oil filter 138. The fan 136 is disposed in the hood 102, and is specifically disposed in the smoke exhaust passage 130. The fan 136 is located above the smoke inlet 104, and at least two smoke guides 106 are located below the smoke inlet 104. The oil filter 138 can be disposed at the smoke inlet 104, or between the smoke inlet 104 and the at least two smoke guides 106.

[0110] Specific embodiment 2, the range hood proposed in the embodiment of the present invention adopts two inclined smoke guides 106 in parallel to solve the technical problems in the related art that the posture of the smoke guide plate 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. The range hood proposed in the embodiment of the present invention uses the oil baffle 118 to form the effect of oil guiding and smoke control, solving the technical problems of oil guiding in the middle area and large impact of smoke entering from the left and right in the related art.

[0111] Specifically, a fan 136 is provided in the smoke exhaust passage 130, a smoke inlet 104 is provided at the bottom of the smoke exhaust passage 130, the smoke inlet 104 is communicated with the smoke guide cavity 132, and an oil filter 138 is installed at the connection between the smoke guide cavity 132 and the smoke exhaust passage 130. A first smoke guide plate 114a and a second smoke guide plate 114b are provided below the oil filter 138, an oil baffle is provided below the first smoke guide plate 114a and the second smoke guide plate 114b, the first smoke guide plate 114a and the second smoke guide plate 114b are arranged side by side on the left and right, and the oil baffle 118 and the oil filter 138 are arranged side by side on the front and back. The oil baffle 118 is located below the oil filter 138, and is tilted from both sides of the range hood to the center from the longitudinal depth to fill the reserved space between the first smoke guide plate 114a and the second smoke guide plate 114b.

[0112] There is a predetermined distance between the smoke guide portion 106 and the oil filter 138 and the oil baffle 118 to ensure that the smoke passes through. The first smoke guide plate 114a is installed in the smoke guide cavity 132 through the first connecting member 116a, and the second smoke guide plate 114b is installed in the smoke guide cavity 132 through the second connecting member 116b. The oil baffle 118 is installed on the front wall and the rear wall of the smoke guide cavity 132.

[0113] The smoke guiding part 106 is rotatably mounted on the smoke guiding cavity 132, and is in a conventional parallel arrangement posture when the work is finished or in a non-working state; in a working state, it is tilted toward the middle, forming a posture with low sides and high middle, so as to effectively and smoothly guide the smoke.

[0114] The first smoke guide plate 114a and the second smoke guide plate 114b have an inclined structure, so that the first smoke guide plate 114a and the second smoke guide plate 114b respectively form two longitudinal smoke inlet cavities; a second gap 144 is formed between the first ends 108 of the first smoke guide plate 114a and the second smoke guide plate 114b, so that the oil smoke gathers at the second gap 144 and then flows downstream; the middle lower-mounted oil baffle 118 effectively divides and guides the flow on the left and right sides to avoid airflow collision and scattering and escape.
