Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, and in particular to an oil fume separation device and an integrated stove. Background Art

[0002] As people's requirements for quality of life increase, range hoods, integrated stoves and other fume extraction equipment that can extract oil fumes during cooking are widely used in people's daily home life to reduce oil fumes in the kitchen during cooking, reduce the harm of oil fumes to human health, and improve the cooking experience.

[0003] In the existing oil fume extraction equipment, a filter is arranged in the smoke inlet. The filter is a metal plate structure with multiple mesh holes for the oil fume to pass through. When the oil fume flows through the filter, part of the oil fume comes into contact with the part of the filter without mesh holes, so that the filter condenses and filters the oil fume, allowing part of the oil contained in the oil fume to adhere to the filter, thereby reducing the oil content in the exhausted oil fume and reducing the pollution of the exhausted oil fume to the external environment.

[0004] However, the filter installed at the smoke inlet usually has a low condensation filtering effect on oil smoke, and it is difficult to take into account the relationship between the extraction efficiency and the condensation effect: if you want to increase the oil fume condensation effect, you need to reduce the opening rate of the filter. The lower the opening rate, the greater the resistance to the flow of oil smoke, the greater the resistance during oil fume extraction, the lower the oil fume extraction efficiency and the higher the noise during the extraction process, resulting in reduced performance of the oil fume extraction equipment.

[0044] Embodiment 1

[0045] like Figures 1 to 6 As shown, this embodiment provides an oil fume separation device 1, which can be applied to equipment capable of extracting oil fumes, such as range hoods or integrated stoves, so as to achieve the adhesion and condensation of grease on the oil fume when the oil fume passes through, thereby achieving oil fume separation and reducing the pollution of the exhaust oil fume to the environment.

[0046] In this embodiment, the oil fume separation device 1 includes a plurality of grid plates 11, and the plurality of grid plates 11 include a plurality of first grid plates 11a and a plurality of second grid plates 11b that are vertically staggered. The first grid plates 11a extend in the left-right direction, and the second grid plates 11b extend in the front-back direction. A smoke channel 12 is formed between two adjacent first grid plates 11a and two adjacent second grid plates 11b. One side of each grid plate 11 is partially recessed toward the other side, so that a plurality of grooves 14 are formed on one side of the grid plate 11 and a plurality of convex bumps 13 are correspondingly formed on the other side.

[0047] The oil fume separation device 1 provided in the present embodiment is provided with a plurality of convex bumps 13 on the grid plate 11. When the oil fume flows through the surface of the convex bumps 13 through the smoke channel 12, part of the oil fume will come into contact with the convex bumps 13 and the grid plate 11, so that the grease contained in the oil fume adheres to the surface of the convex bumps 13, so as to achieve the adhesion and condensation of part of the grease at the grid plate 11, and achieve the separation of part of the grease from the smoke. Since each grid plate 11 is provided with a groove 14 corresponding to the convex bumps 13, when the oil fume flows through the groove 14, a small vortex will be formed at the groove 14 to generate centrifugal force. The centrifugal force generated by the small vortex will throw the oil fume toward the grid plate 11, further increasing the contact area between the grid plate 11 and the oil fume, thereby further enhancing the oil fume separation effect. By providing the convex bumps 13 and the concave grooves 14, the cross-sectional area of ​​the smoke channel 12 does not need to be too small while ensuring the oil fume separation effect, thereby reducing the influence of the setting of the oil fume separation device 1 on the oil fume extraction resistance; furthermore, the plurality of grid plates 11 are vertically staggered, which can reduce the resistance of the oil fume flow grid plates 11 while further increasing the contact area between the grid plates 11 and the oil fume, thereby improving the oil fume separation effect.

[0048] In this embodiment, the first grid plate 11a is perpendicular to the front-to-back direction, and the second grid plate 11b is perpendicular to the left-to-right direction, that is, the first grid plate 11a and the second grid plate 11b are parallel to the extension direction of the smoke channel 12, thereby reducing the influence of the setting of the oil fume separation device 1 on the oil fume extraction resistance and improving the smoothness of the oil fume flowing through the oil fume separation device 1.

[0049] The grid plate 11 is a metal plate with thermal conductivity, so that when the oil smoke contacts the grid plate 11, the oil smoke is condensed, and the oil smoke is attached to the grid plate 11. The convex bump 13 is integrally formed with the grid plate 11. In order to reduce the difficulty of processing, the convex bump 13 is formed by stamping the grid plate 11, so that the groove 14 is naturally formed in the process of stamping the convex bump 13, and the structural strength and rigidity of the grid plate 11 can also be enhanced, and the probability of deformation of the grid plate 11 can be reduced.

[0050] Furthermore, the thickness of the grid plate 11 is 0.4 mm to 0.8 mm, so as to reduce the thickness of the grid plate 11 as much as possible while ensuring the structural strength of the grid plate 11, thereby reducing the resistance of the oil smoke flowing through the grid plate 11.

[0051] The front and rear ends of the second grid plate 11b extend out from the corresponding first grid plate 11a, that is, the two outermost first grid plates 11a are spaced apart from the side wall of the air duct, so that a smoke channel 12 is also formed between the outermost first grid plate 11a and the corresponding side wall of the air duct.

[0052] The width of the smoke channel 12 in the left-right direction is 40 mm to 100 mm, preferably 50 mm to 70 mm, so that the length of the smoke channel 12 in the left-right direction is relatively large to improve the smoothness of the smoke flowing through the smoke channel 12. The width of the smoke channel 12 in the left-right direction can be 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, etc.

[0053] The width of the oil fume separation device 1 in the front-to-back direction is W0, and the width of the smoke channel 12 in the front-to-back direction is W1, 0.2W0<W1<0.4W0, so as to avoid the width of the smoke channel 12 in the front-to-back direction being too narrow, which will increase the oil fume flow resistance, and thus avoid the width of the smoke channel 12 in the front-to-back direction being too large, which will reduce the oil fume separation effect.

[0054] In this embodiment, the number of the first grid plates 11a is three, W1 = (W0-3t) / 4, where t is the thickness of the grid plate 11. It is understandable that the number of the first grid plates 11a can be specifically set according to the width of the air duct where the oil fume separation device 1 is installed, preferably 2 to 4.

[0055] The convex bump 13 is an arc-shaped convex bump, that is, the outer surface of the convex bump 13 is an arc surface, which can reduce the resistance and noise when the oil smoke flows through the convex bump 13. The diameter of the convex bump 13 is preferably 3mm to 6mm, so as to increase the contact area between the convex bump 13 and the oil smoke and improve the processing convenience of the convex bump 13.

[0056] The height of the convex hull 13 protruding from the outer surface of the grid plate 11 is h, where h=t~3t, where t is the thickness of the grid plate 11. More preferably, h=2t~2.5t, so as to increase the surface area of ​​the convex hull 13 while reducing the processing difficulty of the convex hull 13, and avoid increasing the smoke flow resistance due to the convex hull 13 protruding too high.

[0057] In order to increase the number of convex bumps 13 on the grid plate 11, each grid plate 11 is provided with multiple rows of convex bumps 13 from top to bottom, each row of convex bumps 13 includes multiple convex bumps 13 arranged at intervals along the length direction of the grid plate 11, and two adjacent rows of convex bumps 13 are staggered in the length direction of the grid plate 11. In this way, the number of convex bumps 13 can be increased while the area of ​​the grid plate 11 remains unchanged, thereby effectively increasing the contact area between the oil fume separation device 1 and the oil fume.

[0058] Preferably, the upper and lower adjacent rows of convex humps 13 in each row of convex humps 13 are arranged one above the other to improve the layout regularity of the convex humps 13 and reduce the distance between two adjacent convex humps 13, further increasing the number of convex humps 13 that can be arranged.

[0059] In this embodiment, the distance between the centers of two adjacent convex humps 13 in two adjacent rows of convex humps 13 in the left-right direction is d1, and the distance in the front-back direction is d2, d1 = D to 2D, d2 = D to 2D. This arrangement can reduce the distance between the convex humps 13 while avoiding mutual interference between the convex humps 13, and at the same time avoid the convex humps 13 being too dense to cause processing difficulties.

[0060] In order to improve the convenience of disassembly and assembly of the oil fume separation device 1, the first grid plate 11a and the second grid plate 11b are vertically plugged in, so that the first grid plate 11a and the second grid plate 11b can be plugged in or separated. Therefore, when the oil fume separation device 1 is transported or cleaned, multiple first grid plates 11a and second grid plates 11b can be separated to achieve the stacking of the grid plate 11, thereby reducing the space occupied by the oil fume separation device 1 and improving the convenience of transporting and cleaning the oil fume separation device 1.

[0061] The upper and lower sides of the first grid plate 11 a are flush with the upper and lower sides of the second grid plate 11 b to reduce the edges of the oil fume separation device 1 and reduce the scratches on users caused by the protruding edges when carrying or disassembling the oil fume separation device 1 .

[0062] In this embodiment, the first grid plate 11a is provided with a plurality of first slots 11a1 at intervals along the length direction, the first slots 11a1 penetrate the upper side of the first grid plate 11a, and the number of the first slots 11a1 corresponds to the number of the second grid plates 11b. Each second grid plate 11b is provided with a plurality of second slots 11b1 at intervals along the front-back direction, the second slots 11b1 penetrate the lower side of the second grid plate 11b. The height of the grid plate 11 is H0, the height of the first slots 11a1 is H1, and the height of the second slots 11b1 is H2, H1+H2=H0. During assembly, the first slots 11a1 are aligned with the second slots 11b1, and the second grid plate 11b is inserted from top to bottom into the corresponding first slots 11a1 of the plurality of first grid plates 11a, until the portion of the first grid plate 11a located below the first slots 11a1 is inserted into the corresponding second slots 11b1, so that the first grid plate 11a and the second grid plate 11b are arranged flush with each other after plugging.

[0063] It is understandable that the first slot 11a1 may also pass through the lower side of the first grid plate 11a, and the second slot 11b1 may pass through the upper side of the second grid plate 11b, that is, the second grid plate 11b is inserted into the first slot 11a1 from bottom to top.

[0064] It can be understood that the first slot 11a1 and the second slot 11b1 can be set between two adjacent convex bumps 13, and can also be set through the convex bumps 13. Since the material thickness of the convex bumps 13 is relatively small, when the first grid plate 11a and the second grid plate 11b are plugged in, the grid plates 11 can be squeezed against each other to break the convex bumps 13 located at the first slot 11a1 and the second slot 11b1, so that the setting of the convex bumps 13 will not interfere with the insertion between the grid plates 11, and at the same time, the insertion tightness between the two inserted grid plates 11 can be better guaranteed.

[0065] Embodiment 2

[0066] like Figure 7 and Figure 8 As shown, this embodiment provides an integrated stove, which includes a body, a gas stove 6, a functional module 5 and a hood module. Among them, the gas stove 6 is arranged at the upper end of the body, and the functional module 5 is located inside the body and is not limited to a whole box, an oven, a disinfection cabinet, a cabinet, etc. The hood module is used to realize the extraction of oil smoke, which includes a hood head 3 located at the upper end of the body and the rear side of the gas stove 6 and an air duct system located inside the body. The hood head 3 is provided with a smoke inlet 31 and a head air duct 32 connected to the smoke inlet 31; the air duct system has a body air duct, a fan 4 is arranged in the body air duct, and the body air duct and the head air duct 32 together form a smoke exhaust duct. When the fan 4 is running, the generated oil smoke is discharged through the smoke inlet 31 and the smoke exhaust duct in turn.

[0067] In this embodiment, the integrated stove further includes the oil fume separation device 1 provided in the first embodiment. The oil fume separation device 1 is arranged in the smoke exhaust duct to separate the oil fume flowing through the smoke exhaust duct.

[0068] The integrated stove provided by the utility model, by adopting the above-mentioned fume separation device 1, can enhance the fume separation effect during the fume extraction process, and reduce the influence of the setting of the fume separation device 1 on the fume extraction resistance, better take into account the relationship between fume separation and fume extraction resistance, while ensuring the fume extraction effect of the integrated stove, reduce the oil content of the exhausted fume, reduce the pollution of the exhausted fume to the environment, and improve the use experience of the integrated stove.

[0069] The cross section of the exhaust air duct at the installation location of the oil fume separation device 1 is a rectangle, the area of ​​the rectangle is S0, the projection area of ​​the oil fume separation device 1 on the horizontal plane is S1, S1≤0.08S0. That is, in this embodiment, the projection area of ​​the oil fume separation device 1 on the horizontal plane is much smaller than the cross-sectional area of ​​the exhaust air duct at that location, which can effectively reduce the influence of the setting of the oil fume extraction device corresponding to the extraction resistance, and ensure the oil fume extraction effect of the integrated stove.

[0070] Furthermore, the machine body air duct includes a vertical air duct which is vertically arranged and located at the rear side of the functional module 5, the cross section of the vertical air duct is rectangular, and the oil fume separation device 1 is arranged at the upper end of the vertical air duct. Since the structure of the vertical air duct is simpler than that of the machine head air duct 32, it is easier to ensure that the cross section of the vertical air duct is arranged in a rectangular shape at the vertical air duct. Therefore, the oil fume separation device 1 is arranged in the vertical air duct, which can improve the coordination between the oil fume separation device 1 and the smoke exhaust air duct and reduce the processing requirements for the smoke exhaust head 3.

[0071] In this embodiment, the oil fume separation device 1 is interference-fitted into the upper end of the longitudinal air duct 213, so that the cross-section of the oil fume separation device 1 has the same contour as the cross-section of the longitudinal air duct 213, and the installation of the oil fume separation device 1 can be achieved. There is no need to set other structures for installing the oil fume separation device 1 at the longitudinal air duct 213, which effectively improves the structural compactness of the integrated stove and reduces the difficulty of installing the oil fume separation device 1.

[0072] The air duct system includes an air box 2, and the inner cavity of the air box 2 forms a body air duct to better ensure the sealing of the body air duct. In this embodiment, the air box 2 includes a longitudinal air box 21 and a transverse air box 22, the longitudinal air box 21 is vertical and located at the rear side of the functional module 5, and the transverse air box 22 is transversely arranged below the functional module 5. A longitudinal air duct 213 is formed inside the longitudinal air box 21, and a transverse air duct 221 is formed inside the transverse air box 22. The upper end of the longitudinal air duct 213 is connected to the head air duct 32, and the lower end of the longitudinal air duct 213 is connected to the transverse air duct 221. The fan 4 is installed in the transverse air duct 221, and the rotating shaft of the fan 4 is arranged vertically.

[0073] That is, in the embodiment, the bellows 2 is arranged in an L-shape, the body air duct in the bellows 2 is an L-shaped air duct, and the fan 4 is horizontally arranged in the transverse air duct 221, thereby reducing the space occupied by the fan 4 component to the rear of the functional module 5, thereby reducing the size of the integrated stove in the front-to-back direction and improving the structural compactness of the integrated stove, or increasing the size of the functional module 5 in the front-to-back direction on the basis of the unchanged size of the integrated stove in the front-to-back direction, thereby improving the design flexibility of the functional module 5; at the same time, the body air duct is arranged in an L-shape, which can extend the oil fume flow path and is more conducive to the condensation and separation of oil fume between the air ducts.

[0074] Furthermore, the air inlet of the fan 4 is arranged downward and spaced apart from the bottom surface of the transverse air duct 221, so that the oil smoke changes direction once when passing through the connecting point of the transverse air duct 221 and the longitudinal air duct 213, and changes direction for a second time when the transverse air duct 221 enters the air inlet of the fan 4, thereby further increasing the path of the oil smoke entering from the smoke inlet 31 to the air inlet of the fan 4, and at the same time, it can increase the contact area between the oil smoke and the inner wall of the bellows 2 when the oil smoke changes direction, thereby improving the condensation effect and separation effect of the oil smoke in the air duct.

[0075] Furthermore, the longitudinal wind box 21 includes a box body 211, the lower end of which is sealed and connected to the transverse wind box 22, the box body 211 is a hexahedral structure with equal cross-sections, and a longitudinal air duct 213 is formed inside the box body 211. Side extensions 212 extend outwardly from the left and right sides of the box body 211, and the side extensions 212 are used to limit the installation position of the longitudinal wind box 21 in the left and right directions inside the machine body.

[0076] In this embodiment, a filter is provided at the smoke inlet 31 to enhance the oil smoke separation effect of the integrated stove. In other embodiments, the smoke inlet 31 can also be provided in an open manner.

[0077] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
