Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a range hood. Background Technology

[0002] Currently, all range hoods use flat baffles, with two flat baffles arranged side-by-side inside the hood, spaced a predetermined distance apart to create central air intake. However, in actual use, the smoke sources from the two cooktops are located on the left and right sides of the range hood, closer to the user's direction. The flat baffles are positioned slightly outside the center of the cooktop, causing them to almost vertically block the rising smoke, hindering smoke extraction.

[0003] Related technologies disclose flat smoke guides that can be raised or rotated, but in their working state, the smoke guide angle is small, and the smoke guide is almost straight, with the effect being basically the same as that of a flat smoke guide. Therefore, current range hoods all have the drawback that the smoke guiding direction of the smoke guide is the same as the natural flow direction of the smoke source from the stove, which leads to problems such as the smoke guide significantly interfering with the flow of oil fumes, prolonged smoke retention time, long path, and easy smoke escape. Summary of the Invention

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

[0005] Therefore, the present invention provides a range hood.

[0006] The range hood provided by the present invention includes: a smoke hood; a smoke inlet disposed on the smoke hood; at least two smoke guiding parts disposed on the smoke hood, each smoke guiding part including a first end and a second end opposite to each other, the first ends of the at least two smoke guiding parts being close to each other, and the smoke guiding part further including a smoke guiding surface away from the smoke inlet, the smoke guiding surface extending curvedly between the first end and the second end, and being usable for guiding smoke toward the first end and / or the second end.

[0007] The range hood proposed in this invention includes a hood, a smoke inlet, and at least two smoke guides that cooperate with each other. The smoke inlet is disposed on the hood, and the two smoke guides are arranged side-by-side on the hood and used in pairs. The hood may have one or more pairs of smoke guides. Each smoke guide includes a first end and a second end arranged opposite each other. The first ends of the two paired smoke guides are close to each other, and the second ends of the two paired smoke guides are far apart.

[0008] In addition, each smoke guide section includes a smoke guide surface facing away from the smoke inlet. The smoke guide surface extends from the first end of the smoke guide section to the second end of the smoke guide section, and the smoke guide section extends in a curved manner between the first and second ends to form a smoke guide surface that is higher in the middle and lower on both sides. During the operation of the range hood, the smoke guide surface guides the fumes to the first and / or second ends of the smoke guide section, ensuring that the flow direction of the fumes is the same as the smoke guide direction of the smoke guide section.

[0009] Furthermore, for any single smoke guide section, the presence of a smoke guide surface that is higher in the middle and lower on both sides minimizes interference with cooking fumes. When two smoke guide sections are used in pairs, they can form various configurations to adapt to different working conditions, resulting in a shorter flow path for the cooking fumes. During the flow of cooking fumes, the smoke guide section causes minimal interference, reducing the likelihood of liquid condensation and fumes escaping. This effectively solves the problem of significant interference in fume capture caused by the location of the stove center and the range hood center to the side, shortening the residence time of cooking fumes, improving flow, and achieving effective smoke guidance.

[0010] Specifically, most kitchens currently have two cooktops, requiring a single range hood to handle the fumes from both. A certain distance needs to be maintained between the two cooktops, placing them on either side of the center of the hood. Therefore, the range hood proposed in this invention utilizes two paired smoke guides, specifically ensuring that the guide surfaces of these guides are curved. This allows the fumes from both sides of the hood to be expelled through the hood under the guidance of the two guides. Furthermore, the direction of the smoke guides aligns with the direction of smoke generation, effectively addressing the problem of significant fumes capture interference caused by the cooktop center being located to the side of the range hood center. This shortens the fumes' residence time, improves flow, and achieves effective smoke extraction.

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

[0012] In the above technical solution, the smoke guiding surface is an arc surface and protrudes towards the side away from the smoke inlet.

[0013] In this technical solution, the smoke-guiding surface is designed as an arc surface, protruding towards the side opposite to the smoke inlet. Two paired smoke-guiding sections are arranged side-by-side within the range hood, with their smoke-guiding surfaces also arranged side-by-side. The smoke-guiding surfaces of the two paired sections correspond to the positions of the two pots on the stovetop. Thus, during the use of the range hood, the fumes generated from the two stovetops first contact the two smoke-guiding surfaces, specifically the middle of each surface. Then, under the influence of the arc surface, the fumes flow towards the first and / or second ends of the smoke-guiding sections, ensuring that the fumes can be exhausted. Furthermore, the original flow path of the fumes is not altered during this flow, thus greatly reducing obstruction to the fumes.

[0014] In any of the above technical solutions, from the first end to the second end, the distance between the smoke guiding surface and the plane where the smoke inlet is located first increases and then decreases; or from the first end to the second end, the distance between the smoke guiding surface and the plane where the smoke inlet is located gradually increases; or from the first end to the second end, the distance between the smoke guiding surface and the plane where the smoke inlet is located gradually decreases.

[0015] In this technical solution, when the range hood is in use, the two paired smoke guide sections are in a working position. At this time, the positions of the two paired smoke guide sections include, but are not limited to, the following:

[0016] In the first scenario, the distance between the smoke guide surface and the plane containing the smoke inlet first increases and then decreases from the first end to the second end. In other words, the two paired smoke guide surfaces form a W shape. This way, the fumes produced by the stove will flow towards the first and second ends of the smoke guide section after contacting the smoke guide surfaces, causing the fumes to flow simultaneously to both sides and the middle of the hood under the action of the smoke guide surfaces.

[0017] The second scenario involves the distance between the smoke-guiding surface and the plane containing the smoke inlet gradually increasing from the first end to the second end. In other words, the two paired smoke-guiding surfaces form an inverted U-shape. This way, the fumes produced by the stove, upon contact with the smoke-guiding surfaces, will flow towards the first end of the smoke-guiding section, causing the fumes to converge in the middle of the hood under the influence of the smoke-guiding surfaces.

[0018] In the second scenario, the distance between the smoke-guiding surface and the plane containing the smoke inlet gradually decreases from the first end to the second end. In other words, the two paired smoke-guiding surfaces form a U-shape. This way, the fumes produced by the stove, after contacting the smoke-guiding surfaces, will flow towards the second ends on both sides of the smoke-guiding section, causing the fumes to flow to both sides of the hood under the action of the smoke-guiding surfaces.

[0019] It is worth noting that, in either of the above cases, the fumes flow along a curved surface during the process. Compared with the planar design in related technologies, the curved surface is more in line with the natural flow path of fumes, which can greatly reduce the obstruction of the flow of fumes and achieve a better smoke guiding effect.

[0020] In any of the above technical solutions, the smoke guiding part is a smoke guiding plate.

[0021] In this technical solution, the smoke guide section is a smoke guide plate. The smoke guide plate has a flat plate structure, which effectively simplifies the structure of the smoke guide section while ensuring effective smoke diversion, facilitating its manufacturing. More importantly, by using a smoke guide plate, the overall thickness of the smoke guide section can be reduced. This significantly reduces the weight of the smoke guide section while still achieving the desired smoke diversion effect. On the one hand, it reduces the risk of the smoke guide section falling off during use; on the other hand, when using a movable smoke guide section, it reduces the force required for other drive components or manual operation by the user.

[0022] In any of the above technical solutions, the second end of the smoke guide is connected to the smoke hood, and the first end of the smoke guide is a free end.

[0023] In this technical solution, the second end of the smoke guide is connected to the hood, while the first end is used as a free end, making the smoke guide a movable design. During the use of the range hood, the position of the smoke guide can be adjusted according to the actual usage environment to ensure that the position of the guiding surface matches the original flow path of the fumes as closely as possible. This reduces changes to the fume path, minimizes obstruction during the flow of fumes, and further enhances the adaptability of the range hood.

[0024] In any of the above technical solutions, a first gap is formed between the second end of the smoke guide and the smoke hood, and the first gap is connected to the smoke inlet; a second gap is formed between the first ends of the two smoke guides, and the second gap is connected to the smoke inlet.

[0025] In this technical solution, a first gap is formed between the second end of the smoke guide section and the fume hood, and a second gap is formed between the first ends of the two paired smoke guide sections. Both the first and second gaps are connected to the smoke inlet. Thus, when fumes flow to the first end of the smoke guide section under the action of the smoke guide surface, they can be discharged through the second gap; when fumes flow to the second end of the smoke guide section under the action of the smoke guide surface, they can be discharged through the first gap, thereby achieving multi-angle smoke exhaust and selectable exhaust position.

[0026] In any of the above technical solutions, the range hood further includes: a fan, which is installed on the hood, with the fan and two smoke guides located on both sides of the smoke inlet; and an oil filter, which is installed on the hood, with the oil filter located at the smoke inlet or between the smoke inlet and the smoke guides.

[0027] In this technical solution, the range hood also includes a fan and an oil filter. The fan is installed inside the hood, above the smoke inlet, with at least two smoke guide sections located below the smoke inlet. This allows the fan to create negative pressure within the exhaust duct, drawing in the fumes that have entered the smoke guide chamber. The fumes are then drawn into the exhaust duct by the suction force along the paired smoke guide sections.

[0028] In addition, an oil filter screen is installed inside the fume hood. The oil filter screen can be installed at the smoke inlet or between the smoke inlet and at least two smoke guide sections. In this way, the oil fumes pass through the oil filter screen under the drive of the fan, and the small oil droplets mixed in the oil fumes are captured by the oil filter screen.

[0029] In any of the above technical solutions, the middle part of the oil filter screen protrudes towards the fan side.

[0030] In this technical solution, the oil filter screen protrudes from the center towards the fan. During the operation of the range hood, oil fumes enter the oil filter screen under the drive of the fan and pass through the screen to filter out small oil droplets mixed in with the fumes. Because the center of the oil filter screen protrudes upwards, it greatly reduces the likelihood of oil fumes clogging the filter screen and facilitates the drainage of condensed oil on the screen.

[0031] In any of the above technical solutions, the inner wall of the oil filter screen is reduced in the direction from the smoke guide section to the fan.

[0032] In this technical solution, the inner wall of the oil filter is reduced from the direction of the smoke guide to the fan. This allows the oil filter itself to have a certain effect of gathering and collecting oil fumes, and makes the oil filter work in conjunction with the smoke guide cavity to ensure the efficient smoke extraction of the range hood.

[0033] In any of the above technical solutions, the oil filter screen includes: a separating strip, disposed between the fan and the smoke guide section; and two filter screens, connected to both sides of the separating strip, and disposed at an angle relative to the plane where the smoke inlet is located.

[0034] In this technical solution, the oil filter screen includes a separator strip and filter screens disposed on both sides of the separator strip. The middle part of the oil filter screen has a raised section forming the intermediate separator strip, and the two filter screens are inclined outwards to prevent oil dripping from the second gap between the two smoke guide sections while simultaneously guiding the condensed oil on the intermediate separator strip.

[0035] In any of the above technical solutions, the first end of the smoke guide extends between the two filters.

[0036] In this technical solution, the smoke guide extends from the second end to the first end, and the first end of the smoke guide extends between the two filters. This allows the smoke guide to directly direct the fumes to the location of the oil filter. Therefore, during the use of the range hood, when the fumes detach from the first end of the smoke guide, they can be directly sucked away by the negative pressure area above.

[0037] In any of the above technical solutions, the fume hood includes: a smoke exhaust channel having a smoke inlet and a smoke outlet connected together; and a smoke guide cavity connected to the smoke exhaust channel through the smoke inlet, with two smoke guide parts disposed within the smoke guide cavity.

[0038] In this technical solution, the fume hood includes a smoke guiding chamber and a smoke exhaust channel. The smoke exhaust channel is located above the smoke guiding chamber and includes a connected smoke inlet and a smoke outlet. The smoke guiding chamber is connected to the smoke exhaust channel through the smoke inlet, and at least two smoke guiding parts are disposed within the smoke guiding chamber and can guide the oil fumes into the smoke exhaust channel.

[0039] Specifically, the fan is installed inside the smoke exhaust duct, and the smoke guide is installed inside the smoke guide cavity.

[0040] Specifically, vertically, the first end of the smoke guide is located below the smoke inlet of the exhaust duct; horizontally, the second end of the smoke guide is located to the side of the smoke inlet of the exhaust duct. Thus, during the use of the range hood, the two paired smoke guides direct the fumes towards the center of the smoke chamber, where they converge at the second gap formed by the two guides and flow through the gap towards the smoke inlet, ultimately being discharged through the inlet. Correspondingly, the two paired smoke guides also direct the fumes towards the sides of the smoke chamber, where they converge at the first gap formed by the guide and the hood, where they flow through the first gap towards the smoke inlet and ultimately being discharged through the inlet.

[0041] In any of the above technical solutions, the smoke guiding cavity has an opening that is connected to the smoke inlet, and two smoke guiding parts are located between the opening and the smoke inlet.

[0042] In this technical solution, the smoke guiding chamber has an opening located below the smoke guiding section and connected to the smoke inlet. Specifically, the opening area of ​​the smoke guiding chamber is larger than the area of ​​the smoke inlet of the exhaust channel, so that the smoke guide hood can be installed above the stove to initially collect the oil fumes generated by the stove.

[0043] In any of the above technical solutions, the inner wall of the smoke guiding cavity gradually narrows from the opening to the smoke inlet.

[0044] In this technical solution, the inner wall of the smoke guiding cavity is narrowed from the direction of the smoke inlet of the opening, so that the smoke guiding cavity itself has a certain effect of gathering and collecting oil fumes, and the smoke guiding part cooperates with the smoke guiding cavity to ensure the efficient smoke extraction of the range hood.

[0045] In any of the above technical solutions, the range hood further includes: at least two connectors, which are respectively connected to the hood and at least two smoke guides, and the smoke guides are rotatably connected to the hood through the connectors.

[0046] In this technical solution, the range hood also includes connectors, with at least two connectors, the number of which matches the number of smoke guide sections. The connectors are mounted on the hood, and the smoke guide sections are connected to the connectors, thus ensuring the connection between the smoke guide sections and the hood. Furthermore, the smoke guide sections are rotatably connected to the hood via the connectors, which allows the smoke guide sections to be positioned relative to the smoke inlet.

[0047] Specifically, during the adjustment of the smoke guide section, the user can adjust it manually, or a driving component can be installed in the smoke hood to drive the smoke guide section to rotate.

[0048] In any of the above technical solutions, the smoke guide has a third end and a fourth end, and the distance from the third end to the plane where the smoke inlet is located is less than the distance from the fourth end to the plane where the smoke inlet is located.

[0049] In this technical solution, each smoke guide section has a third end and a fourth end. During use, the distance from the third end to the plane containing the smoke inlet is less than the distance from the fourth end to the plane containing the smoke inlet. This causes the smoke guide section to be tilted, allowing it to face the user. This enhances the overall aesthetics of the range hood while ensuring its smoke extraction efficiency. Furthermore, the oil guide hole and the fourth end are located on the same side of the hood, ensuring that the oil-blocking component and the tilt direction of the smoke guide section are consistent, guaranteeing structural harmony.

[0050] Specifically, the first end of the smoke guide is the inner end, the second end is the side end, and the first and second ends are distributed along the left and right direction of the range hood; the third end of the smoke guide is the front end, the fourth end is the rear end, and the third and fourth ends are distributed along the front and back direction of the range hood.

Detailed Implementation

[0063] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0064] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0065] The following reference Figures 1 to 8 This describes a range hood provided according to some embodiments of the present invention. Figure 2 and Figure 5 The dashed line represents the path of the oil fume flow.

[0066] like Figure 1 and Figure 2 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 guide sections 106 that cooperate with each other. The smoke inlet 104 is disposed on the hood 102, and the two smoke guide sections 106 are disposed side-by-side on the hood 102 and used in pairs. The hood 102 may have one or more pairs of smoke guide sections 106. Each smoke guide section 106 includes a first end 108 and a second end 110 disposed opposite to each other. The first ends 108 of the two paired smoke guide sections 106 are close to each other, and the second ends 110 of the two paired smoke guide sections 106 are far apart from each other.

[0067] In addition, such as Figure 3 and Figure 4As shown, each of the smoke guiding sections 106 also includes a smoke guiding surface 112 facing away from the smoke inlet 104. The smoke guiding surface 112 extends from the first end 108 of the smoke guiding section 106 to the second end 110 of the smoke guiding section 106, and the smoke guiding section 106 extends curvedly between the first end 108 and the second end 110 to form a smoke guiding surface 112 that is high in the middle and low on both sides, so as to guide the oil fumes to the first end 108 and / or the second end 110 of the smoke guiding section 106 during the operation of the range hood, ensuring that the flow direction of the oil fumes is the same as the smoke guiding direction of the smoke guiding section 106.

[0068] And, as Figure 5 and Figure 6 As shown, for any one of the smoke guiding sections 106, due to the presence of the smoke guiding surface 112, which is higher in the middle and lower on both sides, the smoke guiding surface 112 can guide the airflow towards the first end 108 and the second end 110 of the flow guiding section 106, resulting in less interference with the oil fumes. When the smoke guiding surfaces 112 of two smoke guiding sections 106 are used in pairs, they can form various postures to adapt to different working conditions, especially suitable for situations where the pot body 200 is offset. This ensures that the flow path of the oil fumes matches the reverse flow path of the smoke guiding surface 112. During the flow of oil fumes, the smoke guiding section 106 causes less interference with the oil fumes, making it less likely for liquid to condense in the oil fumes or for oil fumes to escape. In particular, it solves the problem in related technologies where the center of the stove is to the side of the center of the range hood, causing significant interference in oil fume capture. This shortens the oil fume residence time, makes the flow smoother, and achieves effective smoke guiding.

[0069] Specifically, such as Figure 1 and Figure 2 As shown, most user kitchens are currently equipped with dual stovetops, which means that one range hood has to handle the fumes from both stovetops. A certain distance needs to be maintained between the two stovetops, causing the pots 200 on both stovetops to be located on either side of the center of the hood 102. Therefore, the range hood proposed in this invention uses two paired smoke guides 106, specifically ensuring that the smoke guide surface 112 of the smoke guide 106 is curved. This allows the fumes from both sides of the hood 102 to be discharged from the hood 102 through the two smoke guides 106. Furthermore, the direction of smoke guidance on the smoke guide surface 112 is the same as the direction of smoke generation and flow. This effectively solves the problem of significant fumes capture interference caused by the stovetop being located to the side of the range hood's center, shortening the fumes' residence time, improving flow, and achieving effective smoke guidance.

[0070] The second embodiment of the present invention proposes a range hood, which, based on the first embodiment, further includes, as follows: Figure 5 and Figure 6As shown, the smoke guiding surface 112 is an arc surface and protrudes towards the side opposite to the smoke inlet 104. Two paired smoke guiding sections 106 are arranged side-by-side inside the smoke hood 102, such that the smoke guiding surfaces 112 of the two paired smoke guiding sections 106 are also arranged side-by-side inside the smoke hood 102. The smoke guiding surfaces 112 of the two paired smoke guiding sections 106 correspond to the positions of the two pots 200 on the stovetop.

[0071] Thus, as Figure 5 As shown, during the use of the range hood, the fumes generated from the two stoves first come into contact with the two smoke-guiding surfaces 112, specifically the middle of the surfaces 112. Then, under the influence of the curved surfaces, the fumes flow towards the first end 108 and / or the second end 110 of the smoke-guiding section 106, ensuring that the fumes can be discharged. Furthermore, the original flow path of the fumes remains unchanged during this flow, thus greatly reducing obstruction to the fumes.

[0072] In this embodiment, further, when the range hood is in use, the two paired smoke guide sections 106 are in a working position. At this time, the positions of the two paired smoke guide sections 106 include, but are not limited to, the following:

[0073] In the first scenario, the distance between the smoke-guiding surface 112 and the plane containing the smoke inlet 104 first increases and then decreases from the first end 108 to the second end 110. In other words, the two paired smoke-guiding surfaces 112 form a W-shape. This way, the fumes generated by the stove, upon contact with the smoke-guiding surfaces 112, will flow towards the first end 108 and the second end 110 of the smoke-guiding section 106, respectively, causing the fumes to flow simultaneously to both sides and the center of the hood 102 under the influence of the smoke-guiding surfaces 112.

[0074] In the second scenario, the distance between the plane containing the smoke guiding surface 112 and the smoke inlet 104 gradually increases from the first end 108 to the second end 110. In other words, the two paired smoke guiding surfaces 112 form an inverted U-shape. This way, the fumes generated by the stove will flow towards the first end 108 of the smoke guiding section 106 after contacting the smoke guiding surfaces 112, causing the fumes to converge in the middle of the fume hood 102 under the action of the smoke guiding surfaces 112.

[0075] In the third scenario, the distance between the plane containing the smoke guide surface 112 and the smoke inlet 104 gradually decreases from the first end 108 to the second end 110. In other words, the two paired smoke guide surfaces 112 form a U-shape. As a result, the fumes generated by the stove will flow towards the second ends 110 on both sides of the smoke guide section 106 after contacting the smoke guide surface 112, causing the fumes to flow to both sides of the fume hood 102 under the action of the smoke guide surface 112.

[0076] It is worth noting that, in either of the above cases, the fumes flow along a curved surface during the process. Compared with the planar design in related technologies, the curved surface is more in line with the natural flow path of fumes, which can greatly reduce the obstruction of the flow of fumes and achieve a better smoke guiding effect.

[0077] The third embodiment of the present invention proposes a range hood, which, based on the first embodiment, further includes, as follows: Figure 6 As shown, the smoke guide section 106 is a smoke guide plate. The smoke guide plate has a flat plate structure, which effectively simplifies the structure of the smoke guide section 106 while ensuring the effective flow of cooking fumes, facilitating its manufacturing. More importantly, by using a smoke guide plate, the overall thickness of the smoke guide section 106 can be reduced. While maintaining the smoke guiding effect, the weight of the smoke guide section 106 can be significantly reduced. This reduces the risk of the smoke guide section 106 falling off during use, and when a movable smoke guide section 106 is used, it reduces the force required for other drive components or manual operation by the user.

[0078] In this embodiment, further, as Figure 1 and Figure 2 As shown, the second end 110 of the smoke guide 106 is connected to the hood 102, and the first end 108 of the smoke guide 106 is used as a free end, making the smoke guide 106 a movable design. During the use of the range hood, the position of the smoke guide 106 can be adjusted according to the actual usage environment to ensure that the position of the smoke guide surface 112 matches the original position of the oil fumes as closely as possible, thereby reducing changes to the oil fume path and reducing obstruction of oil fumes during flow, thus further improving the adaptability of the range hood.

[0079] In specific embodiments, such as Figure 1 and Figure 2 As shown, the range hood includes a first smoke guide plate 114a and a second smoke guide plate 114b used in conjunction. The first ends 108 of the first smoke guide plate 114a and the second smoke guide plate 114b are close to each other, and the second ends 110 of the first smoke guide plate 114a and the second smoke guide plate 114b are far apart from each other.

[0080] The fourth embodiment of the present invention proposes a range hood, which, based on the first embodiment, further includes, as follows: Figure 1 and Figure 2 As shown, a first gap 116 is formed between the second end 110 of the smoke guide 106 and the smoke hood 102, and a second gap 118 is formed between the first ends 108 of the two paired smoke guides 106, and the first gap 116 and the second gap 118 are both connected to the smoke inlet 104.

[0081] Thus, as Figure 2As shown, when the fumes flow to the first end 108 of the smoke guide section 106 under the action of the smoke guide surface 112, they can be discharged from the second interval 118; as Figure 2 and Figure 5 As shown, when the fumes flow to the second end 110 of the smoke guide 106 under the action of the smoke guide surface 112, they can be discharged from the first interval 116, thus realizing multi-angle smoke exhaust and selectable smoke exhaust position.

[0082] The fifth embodiment of the present invention proposes a range hood, which, based on the first embodiment, further includes, as follows: Figure 1 and Figure 2 As shown, the range hood also includes a fan 120 and an oil filter 122. The fan 120 is located inside the hood 102, above the smoke inlet 104, and at least two smoke guide sections 106 are located below the smoke inlet 104. This allows the fan 120 to create negative pressure within the exhaust duct 128, drawing in the fumes entering the smoke guide chamber 130. The fumes, under the suction, then follow the paired smoke guide sections 106 into the exhaust duct 128.

[0083] In addition, such as Figure 5 and Figure 6 As shown, an oil filter 122 is also provided inside the fume hood 102. The oil filter 122 can be located at the smoke inlet 104, or it can be located between the smoke inlet 104 and at least two smoke guides 106. In this way, the oil fumes pass through the oil filter 122 under the drive of the fan 120, and the small oil droplets mixed in the oil fumes are captured by the oil filter 122.

[0084] In this embodiment, further, as Figure 7 and Figure 8 As shown, the oil filter 122 protrudes from the center towards the fan 120. During the operation of the range hood, oil fumes enter the oil filter 122 under the drive of the fan 120, and pass through the filter 122 to filter out small oil droplets mixed in with the oil fumes. Because the center of the oil filter 122 protrudes upwards, it can greatly reduce the possibility of oil fumes clogging the oil filter 122, and facilitate the drainage of condensed oil on the oil filter 122.

[0085] In this embodiment, further, as Figure 7 and Figure 8 As shown, the inner wall of the oil filter 122 is narrowed from the smoke guide section 106 to the fan 120. This narrowing of the inner wall of the oil filter 122 allows the oil filter 122 itself to have a certain effect on gathering and collecting oil fumes, and ensures that the oil filter 122 cooperates with the smoke guide cavity 130 to guarantee the efficient smoke extraction of the range hood.

[0086] In this embodiment, further, as Figure 7 andFigure 8 As shown, the oil filter 122 includes a separating band 124 and filter screens 126 disposed on both sides of the separating band 124. The middle part of the oil filter 122 has a raised middle separating band 124, and the two filter screens 126 are inclined to all sides to prevent oil from dripping from the second gap 118 between the two smoke guides 106, while guiding the condensed oil on the middle separating band 124.

[0087] In this embodiment, further, as Figure 7 and Figure 8 As shown, the smoke guide 106 extends from the second end 110 to the first end 108, and the first end 108 of the smoke guide 106 extends between the two filters 126. This allows the smoke guide 106 to directly guide the fumes to the location of the oil filter 122. Therefore, during the use of the range hood, when the fumes detach from the first end 108 of the smoke guide 106, they can be directly sucked away by the negative pressure area above.

[0088] The sixth embodiment of the present invention proposes a range hood, which, based on the first embodiment, further includes, as follows: Figure 1 and Figure 2 As shown, the fume hood 102 includes a smoke guiding chamber 130 and a smoke exhaust channel 128. The smoke exhaust channel 128 is located above the smoke guiding chamber 130 and includes a smoke inlet 104 and a smoke outlet 142 that are connected to each other. The smoke guiding chamber 130 is connected to the smoke exhaust channel 128 through the smoke inlet 104. At least two smoke guiding parts 106 are disposed in the smoke guiding chamber 130 and can guide the oil fumes into the smoke exhaust channel 128.

[0089] Specifically, such as Figure 1 and Figure 2 As shown, the fan 120 is installed in the smoke exhaust duct 128, and the smoke guide 106 is installed in the smoke guide chamber 130.

[0090] Specifically, such as Figure 1 and Figure 2As shown, vertically, the first end 108 of the smoke guide 106 is located below the smoke inlet 104 of the exhaust channel 128; horizontally, the second end 110 of the smoke guide 106 is located to the side of the smoke inlet 104 of the exhaust channel 128. Thus, during the use of the range hood, the two sides of the paired smoke guide chambers 130 guide the fumes towards the center of the smoke guide chamber 130. The guided fumes converge at the second gap 118 formed by the two smoke guides 106, and flow through the second gap 118 to the smoke inlet 104, ultimately being discharged through the smoke inlet 104. Correspondingly, the two sides of the paired smoke guide chambers 130 guide the fumes towards the sides of the smoke guide chamber 130. The guided fumes converge at the first gap 116 formed by the smoke guide 106 and the hood 102, and flow through the first gap 116 to the smoke inlet 104, ultimately being discharged through the smoke inlet 104.

[0091] In this embodiment, further, as Figure 1 and Figure 2 As shown, the smoke guiding chamber 130 has an opening 132, which is located below the smoke guiding section 106 and communicates with the smoke inlet 104. In particular, the area of ​​the opening 132 of the smoke guiding chamber 130 is larger than the area of ​​the smoke inlet 104 of the smoke exhaust channel 128, so that the smoke guide hood 102 can be installed above the stove to initially collect the oil fumes generated by the stove.

[0092] In this embodiment, further, as Figure 1 and Figure 2 As shown, from the direction of the smoke inlet 104 at the opening 132, the inner wall of the smoke guiding cavity 130 narrows, which makes the smoke guiding cavity 130 itself have a certain gathering and collection effect on the oil fumes, and makes the smoke guiding part 106 cooperate with the smoke guiding cavity 130 to ensure the efficient smoke extraction of the range hood.

[0093] The seventh embodiment of the present invention proposes a range hood, which, based on the first embodiment, further includes, as follows: Figure 1 As shown, the range hood also includes connectors, with at least two connectors, the number of which matches the number of smoke guide sections 106. The connectors are mounted on the hood 102, and the smoke guide sections 106 are connected to the connectors, thus ensuring the connection between the smoke guide sections 106 and the hood 102. Furthermore, the smoke guide sections 106 are rotatably connected to the hood 102 via the connectors, which allows the smoke guide sections 106 to be positioned relative to the smoke inlet 104.

[0094] Specifically, during the adjustment of the smoke guide 106, the user can adjust it manually, or a driving component can be installed on the smoke hood 102 to drive the smoke guide 106 to rotate.

[0095] Specifically, such as Figure 1As shown, the range hood includes a first smoke guide plate 114a and a second smoke guide plate 114b, and the connecting parts include a first connector 134a and a second connector 134b. The first smoke guide plate 114a is rotatably mounted on the hood 102 via the first connector 134a, and the second smoke guide plate 114b is rotatably mounted on the hood 102 via the second connector 134b.

[0096] The seventh embodiment of the present invention proposes a range hood, which, based on the first embodiment, further includes, as follows: Figure 3 and Figure 6 As shown, each smoke guide section 106 has a third end 136 and a fourth end 138. During use, the distance from the third end 136 to the plane containing the smoke inlet 104 is less than the distance from the fourth end 138 to the plane containing the smoke inlet 104. This causes the smoke guide section 106 to be tilted, allowing it to face the user. This improves the overall aesthetics of the range hood and ensures efficient smoke extraction. Furthermore, the oil guide hole and the fourth end 138 are located on the same side of the hood 102, ensuring that the oil baffle and the tilt direction of the smoke guide section 106 are consistent, guaranteeing structural harmony.

[0097] Specifically, such as Figure 3 As shown, the first end 108 of the smoke guide 106 is the inner end, and the second end 110 is the side end. The first end 108 and the second end 110 are distributed along the left and right direction of the range hood. The third end 136 of the smoke guide 106 is the front end, and the fourth end 138 is the rear end. The third end 136 and the fourth end 138 are distributed along the front and rear direction of the range hood.

[0098] Specific Implementation Example 1, such as Figure 1 and Figure 2 As shown, the range hood proposed in this specific embodiment includes a hood 102, a smoke inlet 104, and at least two smoke guide sections 106 that cooperate with each other. The smoke inlet 104 is disposed on the hood 102, and the two smoke guide sections 106 are arranged side-by-side on the hood 102 and used in pairs. The hood 102 may have one or more pairs of smoke guide sections 106. Figure 3 and Figure 4 As shown, each smoke guide portion 106 includes a first end 108 and a second end 110 disposed opposite to each other. The first ends 108 of the two smoke guide portions 106 used in pairs are close to each other, and the second ends 110 of the two smoke guide portions 106 used in pairs are far apart from each other. Each smoke guide portion 106 also includes a smoke guide surface 112 facing away from the smoke inlet 104. The smoke guide surface 112 extends from the first end 108 of the smoke guide portion 106 to the second end 110 of the smoke guide portion 106, and the smoke guide portion 106 extends curvedly between the first end 108 and the second end 110 to form a smoke guide surface 112 that is high in the middle and low on both sides.

[0099] Thus, the range hood proposed in this embodiment uses two paired smoke guide sections 106, and in particular, ensures that the smoke guide surface 112 of the smoke guide section 106 is set as a curved surface, so that the oil fumes on both sides of the hood 102 are discharged from the hood 102 through the two smoke guide sections 106. Furthermore, it solves the problem of significant interference in oil fume capture caused by the center of the stove being to the side of the center of the range hood, shortening the oil fume residence time, making the flow more unobstructed, and achieving effective smoke guidance.

[0100] In this embodiment, further, as Figure 5 and Figure 6 As shown, the smoke guiding surface 112 is an arc surface and protrudes towards the side opposite to the smoke inlet 104. Two paired smoke guiding sections 106 are arranged side-by-side inside the smoke hood 102, such that the smoke guiding surfaces 112 of the two paired smoke guiding sections 106 are also arranged side-by-side inside the smoke hood 102. The smoke guiding surfaces 112 of the two paired smoke guiding sections 106 correspond to the positions of the two pots 200 on the stovetop.

[0101] In this embodiment, further, when the range hood is in use, the two paired smoke guide sections 106 are in a working position. At this time, the positions of the two paired smoke guide sections 106 include, but are not limited to, the following:

[0102] In the first scenario, the distance between the smoke-guiding surface 112 and the plane containing the smoke inlet 104 first increases and then decreases from the first end 108 to the second end 110. In other words, the two paired smoke-guiding surfaces 112 form a W-shape. This way, the fumes generated by the stove, upon contact with the smoke-guiding surfaces 112, will flow towards the first end 108 and the second end 110 of the smoke-guiding section 106, respectively, causing the fumes to flow simultaneously to both sides and the center of the hood 102 under the influence of the smoke-guiding surfaces 112.

[0103] In the second scenario, the distance between the plane containing the smoke guiding surface 112 and the smoke inlet 104 gradually increases from the first end 108 to the second end 110. In other words, the two paired smoke guiding surfaces 112 form an inverted U-shape. This way, the fumes generated by the stove will flow towards the first end 108 of the smoke guiding section 106 after contacting the smoke guiding surfaces 112, causing the fumes to converge in the middle of the fume hood 102 under the action of the smoke guiding surfaces 112.

[0104] In the third scenario, the distance between the plane containing the smoke guide surface 112 and the smoke inlet 104 gradually decreases from the first end 108 to the second end 110. In other words, the two paired smoke guide surfaces 112 form a U-shape. As a result, the fumes generated by the stove will flow towards the second ends 110 on both sides of the smoke guide section 106 after contacting the smoke guide surface 112, causing the fumes to flow to both sides of the fume hood 102 under the action of the smoke guide surface 112.

[0105] In this embodiment, further, as Figure 6 As shown, the smoke guide part 106 is a smoke guide plate, which reduces the overall thickness of the smoke guide part 106 and reduces its weight.

[0106] In this embodiment, the second end 110 of the smoke guide 106 is further connected to the smoke hood 102, and the first end 108 of the smoke guide 106 is used as a free end, thus making the smoke guide 106 a movable design.

[0107] In this embodiment, further, as Figure 1 and Figure 2 As shown, a first gap 116 is formed between the second end 110 of the smoke guide 106 and the fume hood 102, and a second gap 118 is formed between the first ends 108 of the two paired smoke guides 106, and both the first gap 116 and the second gap 118 are connected to the smoke inlet 104. The fumes can be discharged from the first gap 116 and / or the second gap 118 under the action of the smoke guide surface 112.

[0108] In this embodiment, further, as Figure 1 and Figure 2 As shown, the range hood also includes a fan 120 and an oil filter 122. The operation of the fan 120 creates negative pressure within the exhaust duct 128, drawing in the fumes entering the smoke guiding chamber 130. Under the influence of suction, the fumes then flow along the paired smoke guiding section 106 into the exhaust duct 128. The oil filter 122 can be located at the smoke inlet 104. Driven by the fan 120, the fumes pass through the filter 122, where small oil droplets mixed with the fumes are captured.

[0109] In this embodiment, further, as Figure 7 and Figure 8 As shown, the middle part of the oil filter screen 122 protrudes towards the fan 120, which can greatly reduce the possibility of oil fumes causing the oil filter screen 122 to become clogged, and facilitate the drainage of condensed oil on the oil filter screen 122.

[0110] In this embodiment, further, as Figure 7 and Figure 8 As shown, from the smoke guide section 106 to the fan 120, the inner wall of the oil filter screen 122 is narrowed, which makes the oil filter screen 122 itself have a certain effect of gathering and collecting oil fumes.

[0111] In this embodiment, further, as Figure 7 and Figure 8As shown, the oil filter 122 includes a separating band 124 and filter screens 126 disposed on both sides of the separating band 124. The middle part of the oil filter 122 has a raised middle separating band 124, and the two filter screens 126 are inclined to all sides to prevent oil from dripping from the second gap 118 between the two smoke guides 106, while guiding the condensed oil on the middle separating band 124.

[0112] In this embodiment, further, as Figure 7 and Figure 8 As shown, the smoke guide 106 extends from the second end 110 to the first end 108, and the first end 108 of the smoke guide 106 extends between the two filters 126. When the oil fumes leave the first end 108 of the smoke guide 106, they can be directly sucked away by the negative pressure area above.

[0113] In this embodiment, further, as Figure 1 and Figure 2 As shown, the fume hood 102 includes a smoke guiding chamber 130 and a smoke exhaust channel 128. The smoke exhaust channel 128 includes a smoke inlet 104 and a smoke outlet 142 that are connected to each other. The smoke guiding chamber 130 is connected to the smoke exhaust channel 128 through the smoke inlet 104. A fan 120 is installed in the smoke exhaust channel 128, and a smoke guiding part 106 is installed in the smoke guiding chamber 130.

[0114] In this embodiment, further, as Figure 1 and Figure 2 As shown, the smoke guiding cavity 130 has an opening 132 located below the smoke guiding section 106 and communicating with the smoke inlet 104. From the direction of the opening 132 to the smoke inlet 104, the inner wall of the smoke guiding cavity 130 narrows.

[0115] In this embodiment, further, as Figure 1 As shown, the first smoke guide plate 114a is rotatably mounted on the smoke hood 102 via the first connector 134a, and the second smoke guide plate 114b is rotatably mounted on the smoke hood 102 via the second connector 134b.

[0116] In this embodiment, further, as Figure 3 and Figure 6 As shown, the smoke guide section 106 has a third end 136 and a fourth end 138, and during the use of the range hood, the distance from the third end 136 to the plane where the smoke inlet 104 is located is less than the distance from the fourth end 138 to the plane where the smoke inlet 104 is located. The smoke guide section 106 is generally inclined and is positioned towards the user.

[0117] Specifically, the first end 108 of the smoke guide 106 is the inner end, and the second end 110 is the side end. The first end 108 and the second end 110 are distributed along the left and right direction of the range hood. The third end 136 of the smoke guide 106 is the front end, and the fourth end 138 is the rear end. The third end 136 and the fourth end 138 are distributed along the front and rear direction of the range hood.

[0118] In a specific embodiment of the present invention, the range hood employs two curved smoke guide sections 106 connected in parallel. This addresses the shortcomings of related technologies where the orientation of the smoke guide plate is inconsistent with the direction of smoke flow on the left and right sides, easily leading to significant interference in smoke flow, long smoke residence time, long path, and easy smoke escape. The range hood proposed in this embodiment utilizes a centrally separated oil filter 122 to achieve both oil guiding and smoke control, thus solving the technical problem of oil guiding in the central area in related technologies.

[0119] Specifically, such as Figure 1 and Figure 2 As shown, a fan 120 is installed inside the smoke exhaust duct 128, and the rotation axis of the fan 120 is parallel to the wall where the range hood is installed. A smoke inlet 104 is located below the smoke exhaust duct 128, and the smoke inlet 104 is connected to the smoke guiding chamber 130. An oil filter 122 is installed at the connection between the smoke guiding chamber 130 and the smoke exhaust duct 128. Below the oil filter 122 are a first smoke guide plate 114a and a second smoke guide plate 114b, which are connected in parallel, forming a series connection with the oil filter 122. Figure 3 and Figure 4 As shown, the first smoke guide plate 114a and the second smoke guide plate 114b are located below the oil filter screen 122. The first smoke guide plate 114a and the second smoke guide plate 114b are curved, forming a posture that is high on the outside and low in the middle, or forming a curved posture that is high on both sides and low in the middle.

[0120] Specifically, such as Figure 5 As shown, there is a predetermined distance between the smoke guide 106 and the oil filter screen 122 to ensure that the oil fumes can pass through; the first smoke guide plate 114a is installed on the left side of the cover through the first connector 134a, and the second smoke guide plate 114b is installed on the right side of the cover through the second connector 134b.

[0121] like Figure 6 As shown, the smoke guide portion 106 has a curved structure, and the smoke guide surface 112 of the smoke guide portion 106 is an arc surface. Figure 5 As shown, from the center of the smoke source, the outer part passes through the edge wall of the smoke guide section 106, flows through the outer smoke guide cavity 130 and enters the smoke inlet 104; from the center of the smoke source, the inner part is guided by the edge wall of the smoke guide plate, flows towards the center of the smoke machine and enters the smoke inlet 104.

[0122] like Figure 7 and Figure 8As shown, the oil filter 122 has an upward-convex structure in the middle, which reduces the blockage of the airflow at the smoke inlet 104 while facilitating the drainage of condensed oil on the filter 122. A dividing strip 124 is provided in the middle convex portion of the oil filter 122, and the two filter screens 126 are inclined outwards to prevent oil dripping from the second gap 118 between the first smoke guide plate 114a and the second smoke guide plate 114b, while simultaneously guiding the condensed oil on the dividing strip 124. Furthermore, the first end 108 of the smoke guide portion 106 extends between the two filter screens 126.

[0123] This invention addresses the problem of significant interference between the two curved smoke guide sections 106 and the flow of smoke from dual-burner stoves, particularly the issue of smoke capture on the center side of the range hood, by employing a solution of tilted arrangement of two curved smoke guide sections 106. This reduces the smoke residence time, improves airflow, and achieves effective smoke guidance. The oil filter 122 has a convex center, which, with a simple structure and without adding components, solves the oil guidance problem in the second valence between the first and second smoke guide plates 114a and 114b. Simultaneously, the three-dimensional oil filter 122 is staggered from the straight smoke inlet 104, reducing airflow blockage losses and improving the air performance of the range hood. Furthermore, an oil cup 140 can be installed below the oil filter 122 to collect condensed oil.

[0124] The range hood proposed in this embodiment of the invention, through the cooperation of the curved first smoke guide plate 114a and second smoke guide plate 114b, the middle raised oil filter 122, and the fan 120, can effectively solve the problems of smoke control and oil circuit in dual-burner smoke sources, while making the airflow smoother and improving the air performance of the range hood.
