Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a smoke collection hood and a range hood. Background Technology

[0002] Existing range hoods include a smoke collection hood. Typically, the smoke collection hood has a first top smoke inlet and / or side smoke inlets. For range hoods with a first top smoke inlet, when the range hood is working, cooking fumes enter the smoke collection hood through the smoke inlet and are eventually transported to the common exhaust duct. When the cooking fumes enter the smoke collection hood, they come into contact with the top wall of the hood, condensing and forming grease. When the grease accumulates to a certain amount, it may drip back onto the cooktop through the first top smoke inlet under gravity, causing oil leakage and pollution.

[0003] To reduce the aforementioned oil leakage and pollution, the relevant technology provides a guide surface on the inner side of the top plate of the range hood's smoke collection hood. The rear side of the guide surface is located behind the first top smoke inlet, and the rear side of the guide surface is lower than the front side of the guide surface. This allows the oil on the guide surface to slide down to the rear side of the guide surface under the action of gravity, and then fall from the rear side of the guide surface onto the bottom plate of the smoke collection hood, and flow backward along the bottom plate into the oil cup of the range hood.

[0004] However, the composition of cooking fumes in the kitchen is complex, including not only unsaturated fatty acids and their derivatives that easily exist in liquid form (such as the thermal decomposition products of peanut oil and soybean oil), but also easily solidified saturated fatty acids and their derivatives (such as the thermal polymerization products of lard and palm oil), as well as solid microparticles (such as products of high-temperature carbonization and minerals from food). The guide surface can only guide the liquid components of the fumes; the easily solidified components and solid microparticles in the fumes that accumulate on the top plate of the fume hood can still easily drip back onto the stove surface through the first top smoke hole, causing oil leakage and pollution. Utility Model Content

[0005] One of the technical problems solved by this utility model is to provide a smoke collection hood that can effectively reduce the possibility of easily solidified components and solid microparticles in oil fumes dripping back onto the stove surface through the first top smoke hole, thereby improving the phenomenon of oil leakage and pollution.

[0006] The second technical problem solved by this utility model is to provide a range hood that can effectively improve the phenomenon of oil leakage and pollution.

[0007] The first technical problem mentioned above is solved by the following technical solution:

[0008] A smoke hood includes a top plate, a bottom plate spaced apart from the top plate, and a first guide member. The bottom plate has a first top smoke inlet at a position opposite to the top plate. The first guide member is located on the side of the top plate facing the bottom plate and between the top plate and the bottom plate. The first guide member includes a guide plate that is inclined downward from front to back. There is a gap between the guide plate and the top plate. The guide plate has a smoke inlet that penetrates the guide plate. The projection of the smoke inlet onto the bottom plate in the vertical direction covers the first top smoke inlet.

[0009] The smoke hood described in this utility model has the following advantages compared with the prior art:

[0010] The first guide component in the aforementioned smoke hood and range hood has a guide plate inclined from front to back. This guide plate directs the liquid components of the fumes impacting the guide plate to the rear of the smoke hood. The easily solidified components and solid particles in the fumes impact the guide plate, specifically outside the smoke inlet hole. Since the projection of the smoke inlet hole onto the bottom plate in the vertical direction covers the first top smoke inlet hole, this location is obviously misaligned with the first top smoke inlet hole in the vertical direction. Therefore, any fumes accumulated at this location that drip will drip onto the bottom plate, achieving an initial reduction of the easily solidified components and solid particles in the fumes. Additionally, some fumes enter the gap between the guide plate and the top plate through the smoke inlet hole. This portion of fumes impacts the top plate and accumulates there. When the easily solidified components and solid particles accumulated on the top plate drip again, some will be caught by the guide plate, further reducing the amount of easily solidified components and solid particles in the fumes. It is worth emphasizing that the guide plate protrudes from the top plate and has a certain turbulence effect. The direction of the oil fume entering the fume hood will be changed, diverting some of the oil fume to the top plate around the guide plate and accumulating on the top plate. This will offset it from the first top smoke hole in the vertical direction. Even if it drips, it will drip onto the bottom plate. This also reduces the possibility of easily solidified components and solid particles in the oil fume dripping from the first top smoke hole to a certain extent.

[0011] Clearly, the first guide member not only has a turbulent effect, reducing the possibility of oil fumes accumulating on it, but also, compared to the guide surface in the prior art, allows easily solidified components and solid particles in the oil fumes to be misaligned multiple times with the first top smoke hole (the guide surface only allows for a single misalignment), further reducing the possibility of easily solidified components and solid particles dripping from the first top smoke hole. Furthermore, the first guide member also has the same function as the guide surface, guiding the liquid components in the oil fumes. In other words, the first guide member reduces both the possibility of liquid components dripping from the first top smoke hole and the possibility of easily solidified components and solid particles dripping from the first top smoke hole, thus effectively improving the oil leakage pollution phenomenon.

[0012] In one embodiment, multiple first top smoke inlets and smoke inlets are provided, and the first top smoke inlets and smoke inlets are arranged to cover and face each other in the vertical direction.

[0013] In one embodiment, a second guide is provided on the side of the top plate facing the bottom plate. The second guide is inclined downward from front to back, and at least the rear end of the smoke inlet is located below the second guide, and the projection of the smoke inlet on the top plate in the vertical direction falls on the second guide.

[0014] In one embodiment, the top surface of the guide plate is provided with a first oil-blocking protrusion surrounding the wall of the smoke inlet.

[0015] In one embodiment, the first guide member further includes a first connecting portion and a second connecting portion, the first connecting portion connecting the rear side of the guide plate and the top plate, and the second connecting portion connecting the front side of the guide plate and the top plate.

[0016] In one embodiment, the first connecting portion is provided with a first oil guide hole.

[0017] In one embodiment, the first guide member further includes a fourth connecting portion and a third connecting portion, the fourth connecting portion connecting the left end of the guide plate and the top plate, and the third connecting portion connecting the right end of the guide plate and the top plate.

[0018] In one embodiment, the top plate has a flange on the side facing the bottom plate, and the flange has a hook hole. The first guide also includes a hook part. At least one of the fourth connecting part and the third connecting part is provided with the hook part near the flange, and the hook part is hooked to the hook hole.

[0019] In one embodiment, the first guide member further includes a first reinforcing portion disposed on the rear side of the guide plate, and the first reinforcing portion has a second oil guide hole; and / or, the first guide member further includes a second reinforcing portion disposed on the front side of the guide plate.

[0020] The second technical problem mentioned above is solved by the following technical solution:

[0021] A range hood includes a fan assembly and any of the aforementioned smoke collection hoods, wherein the fan assembly is disposed above the smoke collection hood.

[0022] Compared with the prior art, the range hood of this utility model has the following advantages: by setting the first guide member and the smoke inlet hole on the first guide member, the oil fumes are misaligned with the first top smoke inlet multiple times, reducing the possibility of oil fumes dripping from the first top smoke inlet, thereby effectively improving the oil leakage and pollution phenomenon.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The embodiments of this utility model propose a smoke collection hood 10 and a range hood, such as Figures 1-10 As shown, the range hood includes a smoke collection hood 10, a fan assembly 20, and an oil cup 30. The fan assembly 20 is positioned above and communicates with the smoke collection hood 10, and the oil cup 30 is installed on the lower side of the smoke collection hood 10. The smoke collection hood 10 includes a horizontal smoke gathering section 100, within which a horizontal smoke gathering chamber is formed. The horizontal smoke gathering section 100 includes a top plate 1, a bottom plate 2 spaced apart from the top plate 1, and a back plate 3 connected to the rear side of the top plate 1. The fan assembly 20 is connected to the top plate and communicates with the horizontal smoke gathering chamber through an air outlet. A first top smoke extraction hole 2a communicating with the horizontal smoke gathering chamber is provided on the bottom plate 2 at a position opposite to the top plate 1. The horizontal smoke collection section 100 also includes a first guide member 4 disposed within the horizontal smoke collection chamber. The first guide member 4 is fixed to the side of the top plate 1 facing the bottom plate 2 by means of welding, screws, or rivets, and is located between the top plate 1 and the bottom plate 2. The first guide member 4 includes a guide plate 41 inclined downward from front to back, with a gap between the guide plate 41 and the top plate 1. A smoke inlet hole 41a is provided on the guide plate 41, penetrating the guide plate 41. The projection of the smoke inlet hole 41a along the vertical direction on the bottom plate 2 covers the first top smoke inlet hole 2a. The shape of the smoke inlet hole 41a includes, but is not limited to, regular or irregular shapes such as circles, ellipses, and waist shapes. It can be flexibly adjusted and set according to actual needs, and is not specifically limited here. In this embodiment, the first top smoke inlet hole 2a is set as a waist-shaped hole extending in the front-back direction, and the smoke inlet hole 41a is also set as a waist-shaped hole with the same extension direction as the first top smoke inlet hole 2a.

[0041] It should be noted that the rear side of the top plate 1 refers to the area where the range hood is installed in a normal position on the wall of the environment such as the kitchen, with the ground as the reference horizontal plane, the direction closer to the user as the front, and the direction farther from the user as the rear.

[0042] The aforementioned smoke hood 10 and the first guide member 4 in the range hood have a guide plate 41 inclined from front to back. This guide plate 41 directs the liquid components of the fumes impacting the guide plate 41 to the rear side of the smoke hood 10. The easily solidified components and solid particles in the fumes impact the guide plate 41, specifically hitting a position outside the smoke inlet 41a. Since the projection of the smoke inlet 41a vertically onto the base plate 2 covers the first top smoke inlet 2a, and this position is obviously misaligned with the first top smoke inlet 2a in the vertical direction, the fumes accumulated at this position will drip onto the base plate 2 instead of dripping from the first top smoke inlet 2a outside the smoke hood 10. This effectively prevents the easily solidified components in the fumes from impacting the base plate 2. In addition to the initial reduction of fumes and solid particles, some oil fumes enter the gap between the guide plate 41 and the top plate 1 through the smoke inlet 41a. This part of the oil fumes impacts the top plate 1 and accumulates on it. When the easily solidified components and solid particles accumulated on the top plate 1 drip down again, some of them will be caught by the guide plate 41, instead of dripping directly from the smoke inlet 41a and the first top smoke inlet 2a to the outside of the smoke collection hood 10. This achieves a further reduction of easily solidified components and solid particles in the oil fumes. Moreover, the guide plate 41 can guide the liquid components in the oil fumes that drip from the top plate 1 to the first guide member 4 to the rear side of the smoke collection hood 10, thereby further reducing the possibility of liquid components in the oil fumes dripping from the first top smoke inlet 2a. It is worth emphasizing that the first guide member 4 protrudes from the top plate 1 and has a certain turbulence effect. The direction of the oil fume entering the fume hood 10 will be changed, diverting some of the oil fume to the top plate 1 around the guide plate 41 and accumulating on the top plate 1. Thus, it is vertically offset from the first top smoke hole 2a. Even if it drips, it will drip onto the bottom plate 2 and will not drip from the first top smoke hole 2a to the outside of the fume hood 10. This also reduces the possibility of easily solidified components and solid particles in the oil fume dripping from the first top smoke hole 2a to a certain extent.

[0043] Clearly, the first guide member 4 not only has a turbulent effect, reducing the possibility of oil fumes accumulating on it, but also, compared to the guide surface in the prior art, allows easily solidified components and solid particles in the oil fume to be misaligned multiple times with the first top smoke hole 2a (the guide surface only allows for a single misalignment), further reducing the possibility of easily solidified components and solid particles dripping from the first top smoke hole 2a. Furthermore, the first guide member 4 also has the same function as the guide surface, guiding the liquid components in the oil fume. In other words, the first guide member 4 reduces both the possibility of liquid components dripping from the first top smoke hole 2a and the possibility of easily solidified components and solid particles dripping from the first top smoke hole 2a, thereby effectively improving the oil leakage pollution phenomenon.

[0044] Specifically, multiple first top smoke inlets 2a are provided, and one smoke inlet 41a can correspond to multiple first top smoke inlets 2a simultaneously. Alternatively, in the current embodiment, multiple first top smoke inlets 2a and smoke inlets 41a are provided at intervals along the left and right directions, and the smoke inlets 41a and the first top smoke inlets 2a are arranged one-to-one in the vertical direction. Compared with one smoke inlet 41a corresponding to multiple first top smoke inlets 2a, the area occupied by the smoke inlets 41a on the guide plate 41 is smaller while the overall size of the guide plate 41 remains unchanged. The guide plate 41 has a better blocking effect on easily solidified components and solid particles in the oil fume.

[0045] like Figure 3 As shown, in order to guide the liquid components in the fumes that accumulate on the top plate 1 through the smoke inlet 41a, a second guide 6 is provided on the side of the top plate 1 facing the bottom plate 2. The second guide 6 is inclined downward from front to back, and at least the rear end of the smoke inlet 41a is located below the second guide 6 and its vertical projection on the top plate 1 falls on the second guide 6. In this way, the fumes that should have hit the top plate 1 through the smoke inlet 41a will hit the second guide 6 and flow towards the rear side of the smoke collection hood 10 under the guidance of the second guide 6.

[0046] In this embodiment, the projection of the smoke inlet 41a onto the top plate 1 in the vertical direction falls entirely on the second guide member 6, so that most of the oil fumes impacting the top plate 1 through the smoke inlet 41a can be guided by the second guide member 6.

[0047] For example, the second guide member 6 is formed by stamping directly onto the top plate 1, and the inclination angle of the second guide member 6 relative to the horizontal plane is between 4-20°. For example, the inclination angle of the second guide member 6 can be set at 4°, 10°, or 20°. If the angle is too large, the processing difficulty is high; if the angle is too small, the guiding effect is poor. The inclination angle of the guide plate 41 relative to the horizontal plane can also be set between 4-20°. Of course, the second guide member 6 can also be formed independently and fixed to the top plate 1 by means of welding or bolt connection, not limited to welding or bolt connection.

[0048] In some embodiments, to reduce the possibility of oil fumes flowing from the top surface of the baffle 41 to the smoke inlet 41a, such as... Figure 7 and Figure 10 As shown, the top surface of the guide plate 41 is provided with a first oil-blocking protrusion 411 surrounding the wall of the smoke inlet 41a. Specifically, the smoke inlet 41a and the first oil-blocking protrusion 411 are integrally stamped. When processing the smoke inlet 41a, the guide plate 41 is stamped from bottom to top, thereby forming the smoke inlet 41a and the first oil-blocking protrusion 411.

[0049] In some embodiments, the first guide member 4 can be connected to the top plate 1 front and rear, specifically, such as Figures 5-7As shown, the first guide member 4 also includes a second connecting portion 42 and a first connecting portion 43. The first end of the second connecting portion 42 is connected to the front side of the guide plate 41, and the second end of the second connecting portion 42 is fixed to the top plate 1. The first end of the first connecting portion 43 is connected to the rear side of the guide plate 41, and the second end of the first connecting portion 43 is connected to the top plate 1. More specifically, both the second connecting portion 42 and the first connecting portion 43 are L-shaped, and the guide plate 41, the second connecting portion 42, and the first connecting portion 43 are integrally bent. Exemplarily, both the first connecting portion 43 and the second connecting portion 42 are provided with connecting holes, and the top plate 1 is connected to the first guide member 4 through fasteners that pass through the connecting holes.

[0050] Based on this, the left and right sides of the first guide member 4 may not be surrounded, and the oil fumes will flow away from the left and right sides of the guide plate 41. Alternatively, the first connecting part 43 may be provided with a first oil guide hole 4a, and the oil fumes will flow out from the first oil guide hole 4a provided on the rear side of the first guide member 4.

[0051] In other embodiments, the first guide member 4 can be connected to the top plate 1 on the left and right sides. Specifically, as shown in the figure... Figures 8-10 As shown, the first guide member 4 includes a guide plate 41, a fourth connecting part 47, and a third connecting part 48. The first end of the fourth connecting part 47 is connected to the left end of the guide plate 41, and the second end of the fourth connecting part 47 is fixed to the top plate 1. The first end of the third connecting part 48 is connected to the right end of the guide plate 41, and the second end of the first connecting part 48 is connected to the top plate 1. More specifically, both the fourth connecting part 47 and the third connecting part 48 are L-shaped, and the guide plate 41, the fourth connecting part 47, and the third connecting part 48 are integrally bent into shape.

[0052] like Figure 1 and Figure 4 As shown, to achieve uniformity in the entry of oil fumes into the fume collection hood 10, the air outlet is centrally located in the horizontal fume collection section 100. A second top smoke extraction hole group is provided on the base plate 2 corresponding to the air outlet position. The second top smoke extraction hole group includes multiple second top smoke extraction holes 2b spaced apart along the left-right direction. To fully absorb the oil fumes, first top smoke extraction holes 2a are provided on both the left and right sides of the air outlet on the base plate 2. Multiple first top smoke extraction holes on the same side of the air outlet constitute a first top smoke extraction hole group. Furthermore, first guide members 4 are provided on both the left and right sides of the air outlet to guide the oil fumes entering through the first top smoke extraction hole groups on the left and right sides of the air outlet, respectively. It is understood that oil fumes entering from the second top smoke extraction hole group directly opposite the air outlet will be directly sucked away by the fan assembly 20, and the possibility of oil fume dripping is relatively lower than that from the first top smoke extraction hole group. For example, both the first and second top smoke extraction hole groups are provided in two sets.

[0053] Specifically, there are two top plates 1 spaced apart in the left and right direction, and an air outlet is formed between the two top plates 1. The projections of the first top smoke hole group located on the left and right sides of the air outlet in the vertical direction fall on the two top plates 1 respectively.

[0054] To facilitate the connection between the fan assembly 20 and the top plate 1, the top plate 1 has a downwardly bent flange 11 on one side forming the air outlet. That is, the flange 11 is provided on the side of the top plate 1 facing the bottom plate 2. The fan assembly 20 and the top plate 1 are connected by fasteners passing through the flange 11. Based on the premise that the first guide member 4 includes a fourth connecting part 47 and a third connecting part 48, the first guide member 4 also includes a hook part 46. The flange 11 is provided with a hook hole, and at least one of the fourth connecting part 47 and the third connecting part 48 near the flange 11 is provided with a hook part 46. When the first guide member 4 is fixed to the top plate 1, the hook part 46 can be hooked onto the hook hole first to achieve positioning, and then the first guide member 4 can be fixed to the flange using fasteners, thereby reducing the difficulty of assembling the first guide member 4 onto the top plate 1.

[0055] In this embodiment, both the fourth connecting portion 47 and the third connecting portion 48 are provided with hook portions 46, and both the fourth connecting portion 47 and the third connecting portion 48 are provided with connecting holes for fasteners to pass through. The first guide member 4 has a symmetrical structure, so the first guide members 4 on both the left and right sides are interchangeable, reducing the processing cost and assembly difficulty of the first guide member 4. In other embodiments, the hook portion 46 can be provided on the fourth connecting portion 47, while the mounting hole for fasteners to pass through can be provided on the third connecting portion 48; or the hook portion 46 can be provided on the third connecting portion 48, while the mounting hole for fasteners to pass through can be provided on the fourth connecting portion 47.

[0056] It is understandable that the hook part 46 can also be provided on the first connecting part 43 and / or the second connecting part 42, and the hook part 46 is inserted upward into the top plate 1.

[0057] refer to Figure 10 As shown, the first guide member 4 also includes a second reinforcing part 44 and / or a first reinforcing part 45. The second reinforcing part 44 and the first reinforcing part 45 are also integrally bent and formed on the guide plate 41. The second reinforcing part 44 is bent upward and disposed on the front side of the guide plate 41, and the first reinforcing part 45 is bent upward and disposed on the rear side of the guide plate 41. A second oil guide hole 4b is provided on the first reinforcing part 45. The provision of the second reinforcing part 44 and the first reinforcing part 45 can increase the structural strength and structural stability of the first guide member 4.

[0058] refer to Figure 1 and 2As shown, the range hood is a 7-shaped range hood. Based on this, the smoke collection hood 10 also includes a vertical smoke collection part 200, which is connected to the rear side of the horizontal smoke collection part 100. The vertical smoke collection part 200 has a vertical smoke collection chamber that communicates with the horizontal smoke collection chamber. The vertical smoke collection part 200 includes a panel 5 that is disposed opposite to the back panel 3. The panel 5 is connected to the bottom plate 2 located above the panel 5 through an arc-shaped transition part. The oil cup 30 is disposed at the bottom of the vertical smoke collection part 200. The bottom plate 2 is inclined from front to back. In this way, the oil fumes dripping onto the bottom plate 2 will flow to the rear side, then flow to the panel 5 through the arc-shaped transition part, and then flow to the oil cup 30 through the panel 5. A side smoke extraction hole communicating with the vertical smoke collection part 200 is also provided between the lower end of the panel 5 and the oil cup 30.

[0059] Specifically, to prevent oil fumes on the base plate 2 from dripping down the first top smoke hole 2a, a second oil-blocking protrusion 21 is provided on the inner side of the base plate 2 around the hole wall of the first top smoke hole 2a. The second oil-blocking protrusion 21 can be integrally stamped with the first top smoke hole 2a.

[0060] The fumes entering the horizontal smoke collection chamber through the first top smoke inlet 2a condense on the first guide member 4 after contact with it. The liquid components slide down the guide plate 41 from front to back, while some fumes enter the gap between the guide plate 41 and the top plate 1. Some of this fumes accumulate on the top plate 1 and slide down the second guide member 6 from front to back, while some drips onto the first guide member 4 and slide down the guide plate 41 from front to back. The fumes that slide down the first and second guide members 4 and 6 both slide down the bottom plate 2 from front to back and then enter the oil cup 30, reducing the possibility of fumes falling onto the stove surface.

[0061] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0062] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
