[0002] The information provided in this section is only background information related to the present disclosure, and it is not necessarily prior art.

[0003] At present, the smoke collecting openings of integrated stoves at home and abroad are mainly circular and rectangular in shape. The smoke collecting openings are flat against the cooking stove surface, resulting in the distance between the smoke collecting opening and the heating area on the cooking stove surface being closer to the oil fume area on the cooking stove surface. When using the integrated stove with such a smoke collecting opening during cooking, it is very difficult for the oil fume to be sucked away by the smoke collecting opening along the parabolic trajectory, resulting in a poor overall smoking effect of the integrated stove. At the same time, the smoke collecting opening will also suck away part of the heat of the cooking appliance, resulting in an unsatisfactory cooking effect of the cooking appliance.

[0004] For the existing electric smoke collecting opening liftable integrated stove, power is provided by a cylindrical column type reduction motor, and a push rod is used to drive the smoke collecting plate at the smoke collecting opening to perform a cylindrical motion, so as to realize the lifting of the smoke collecting plate at the smoke collecting opening along a fixed trajectory and increase the smoking height of the smoke collecting plate.

Detailed Description of the Preferred Embodiments

[0030] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that the application of the smoke gathering device of the present invention to a combined device with a smoke gathering device and a cooking range is only a preferred embodiment, and it does not limit the application scope of the smoke gathering device of the present invention. For example, the smoke gathering device of the present invention can also be applied to other gas appliances, and such an adjustment belongs to the protection scope of the smoke gathering device of the present invention.

[0031] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", and "having" are inclusive and thus specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0032] In the description of the present invention, unless otherwise clearly defined and limited, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0034] For ease of description, spatial relative relationship terms may be used in the text to describe the relationship of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inner", "circumferential", "upper", "end", "horizontal", "tilted", "top", "bottom", "side", etc. Such spatial relative relationship terms are intended to include different orientations of the mechanism during use or operation in addition to the orientations depicted in the figure. For example, if the mechanism in the figure is flipped, then an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "over other elements or features". Thus, the exemplary term "below" can include both the upper and lower orientations. The mechanism can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0035] As Figures 1 to 3 shown, according to an embodiment of the first aspect of the present invention, the first aspect of the present invention provides a fume collecting device 100. The fume collecting device 100 includes a fume collecting cylinder 20 and a lifting mechanism (which will be introduced in detail below). The fume collecting cylinder 20 is disposed at the fume collecting opening 101 of a cooking range (not shown in the figure). The cooking fumes generated by the cooking range flow to the fume collecting opening 101 through the fume collecting cylinder 20. The lifting mechanism includes a link assembly 40 and a motor assembly (which will be elaborated in detail below). The link assembly 40 includes a first link 41. The first end 411 of the first link 41 is horizontally slidably connected to the fume collecting cylinder 20, and the second end 412 of the first link 41 is connected to the rotating member of the motor assembly (which will be introduced in detail below). The motor assembly drives the fume collecting cylinder 20 to lift at the fume collecting opening 101 through the link assembly 40.

[0036] When the fume collecting device 100 of the present invention is in use on the cooking range, the fume collecting cylinder 20 is driven to rise at the fume collecting port 101 through the lifting mechanism, and the fume on the cooking range is sucked through the fume collecting cylinder 20. When the cooking range is in the rest state, the fume collecting cylinder 20 is driven to descend at the fume collecting port 101 through the lifting mechanism, reducing the space occupied by the fume collecting device 100, thereby improving the user experience. Specifically, a panel 10 is provided on the cooking range. One or more gas stoves can be provided on the panel 10 of the cooking range. Taking the example that two gas stoves are provided on the panel 10 of the cooking range at intervals, a fume collecting port 101 is provided at the position between the two gas stoves on the panel 10. An accommodating space located below the fume collecting port 101 is provided at the position between the two gas stoves in the cooking range. A blower is provided at the bottom of the accommodating space. A fume collecting device 100 is provided at the position of the fume collecting port 101 at the top of the accommodating space. The fume collecting device 100 includes a fume collecting cylinder 20 that is in clearance fit with the fume collecting port 101 and a driving mechanism that drives the fume collecting cylinder 20 to lift and lower. The blower is communicated with the fume collecting cylinder 20 of the fume collecting device 100. When the gas stove is in the working state, the lifting mechanism of the fume collecting device 100 drives the fume collecting cylinder 20 to rise above the panel 10, and then the blower extracts the air in the fume collecting cylinder 20 to form a negative pressure at the fume collecting cylinder 20 and the fume collecting port 101, so that the fume generated by the two gas stoves during use converges towards the fume collecting port 101 and flows into the blower through the fume collecting cylinder 20, and then is discharged through the exhaust pipe on the blower. When the gas stove is in the rest state, the lifting mechanism of the fume collecting device 100 drives the fume collecting cylinder 20 to descend below the panel 10, and the cover plate around the fume collecting cylinder 20 covers the gap between the side wall of the fume collecting cylinder 20 and the fume collecting port 101, reducing the debris on the cooking range from falling into the fume collecting cylinder 20 through the gap between the side wall and the fume collecting port 101.

[0037] Further, the motor assembly in the above embodiment drives the fume collecting cylinder 20 to lift and lower through the connecting rod assembly 40, and the connecting rod assembly 40 is circumferentially connected to the fume collecting cylinder 20, which can improve the stability of the fume collecting cylinder 20 during the lifting and lowering process, reduce the phenomenon of local stress concentration of the fume collecting cylinder 20 during the lifting and lowering process, and reduce the phenomenon of damage to the fume collecting cylinder 20 due to stress concentration and the phenomenon of shaking left and right, front and back during the lifting and lowering process. It should be noted that the connecting rod assembly 40 can be selected from two-link, three-link, four-link and other multi-link structures. The specific structure of the connecting rod assembly 40 will be elaborated in detail below. The connecting rod assembly 40 is connected to the fume collecting cylinder 20 through multiple connecting rods. The motor assembly realizes the purpose of synchronous movement of multiple connecting rods by driving at least one connecting rod in the connecting rod assembly 40. Multiple connecting rods drive the fume collecting cylinder 20 to lift and lower at the same time, thereby reducing the phenomenon of local stress concentration of the fume collecting cylinder 20 and improving the stability of the fume collecting cylinder 20 during the lifting and lowering process.

[0038] Such as Figure 4 and Figure 5As described above, according to an embodiment of the present invention, the connecting rod assembly 40 further includes a second connecting rod 42 that is cross-connected to the first connecting rod 41. The first end 421 of the second connecting rod 42 is horizontally slidably connected to the cooking range top, and the second end 422 of the second connecting rod 42 is horizontally slidably connected to the smoke collecting hood 20.

[0039] In this embodiment, the first connecting rod 41 and the second connecting rod 42 are pivotally connected by a first axial screw 33. When the motor assembly drives any one of the connecting rods in the connecting rod assembly 40, for example, the motor assembly drives the first connecting rod 41 and / or the second connecting rod 42, the second connecting rod 42 of the connecting rod assembly 40 can rotate with the first end 421 of the second connecting rod 42 as a fulcrum. During the rotation of the second connecting rod 42, the second connecting rod 42 drives the first axial screw 33 to rotate. During the rotation of the first axial screw 33, it moves up and down in the vertical direction. During the up and down movement of the first axial screw 33, it drives the second end 422 of the second connecting rod 42 and the first end 411 of the first connecting rod 41 to move up and down. The second end 422 of the second connecting rod 42 and the first end 411 of the first connecting rod 41 drive the smoke collecting hood 20 to move up and down during the up and down movement. Further, in order to prevent the second connecting rod 42 from jamming during the rotation process, the first end 411 of the first connecting rod 41 is horizontally slidably connected to the smoke collecting hood 20, and the second end 422 of the second connecting rod 42 is horizontally slidably connected to the smoke collecting hood 20. During the rotation of the second connecting rod 42, the first end 411 of the first connecting rod 41 slides horizontally on the smoke collecting hood 20. A flanging structure is formed at the second end 422 of the second connecting rod 42, and the flanging structure slides horizontally in a kidney-shaped hole (not shown in the figure) of the smoke collecting hood 20 through an axial screw.

[0040] Further, the smoke collecting device 100 further includes a mounting plate assembly 11 disposed on the inner wall of the panel 10. The motor assembly and a part of the connecting rod assembly 40 are disposed on the mounting plate assembly 11. Specifically, the mounting plate assembly 11 includes a first mounting plate 111 and a second mounting plate 112 disposed on the inner wall of the panel 10 and around the smoke collecting opening 101. The first end 421 of the second connecting rod 42 is horizontally slidably connected to a kidney-shaped hole on the first mounting plate 111, and the second end 422 of the second connecting rod 42 is horizontally slidably connected to a kidney-shaped hole (not shown in the figure) of the smoke collecting hood 20. The mounting plate assembly 11 further includes a second mounting plate 112 disposed on the inner wall of the panel 10 and away from the smoke collecting opening 101. The motor assembly is mounted on the second mounting plate 112. Setting the motor assembly at a position away from the smoke collecting opening 101 can reduce the influence of the oil fume at the smoke collecting opening 101 on the motor assembly.

[0041] As Figure 4 and Figure 5As shown, according to an embodiment of the present invention, the motor assembly includes a reduction motor 30 and a bushing 32. One end of the bushing 32 is connected to the rotating shaft of the reduction motor through a motor connection plate 31, and the other end of the bushing 32 is connected to the second end 412 of the first link 41.

[0042] In this embodiment, the connection between the rotating shaft of the reduction motor 30 and the motor connection plate 31 is a flat position connection. The output end of the rotating shaft of the reduction motor 30 is set as a prism structure, and a prism groove matching the prism structure is provided on the motor connection plate 31. The rotating shaft and the motor connection plate 31 are matched by the prism and the prism groove, so that the rotating shaft can drive the motor connection plate 31 to rotate. The bushing 32 is connected to the motor connection plate 31 and the first link 41 by a card slot connection. Clamping strips are provided at both ends of the outer wall of the bushing 32, and card slots matching the clamping strips are provided on the motor connection plate 31 and the first link 41. The driving force is transmitted between the motor connection plate 31, the bushing 32 and the first link 41 through the clamping strips and the card slots. The motor connection plate 31 and the bushing 32 play a role in transmitting the driving force of the reduction motor, so that the rotating shaft can drive the first link 41 to rotate through the motor connection plate 31 and the bushing 32, and separate the reduction motor 30 from the link assembly 40 and the smoke collecting cylinder 20 through the motor connection plate 31 and the bushing 32, reducing the interference between the reduction motor 30 and the link assembly 40 and the smoke collecting cylinder 20.

[0043] Continue to refer to Figures 1 to 5 , according to an embodiment of the present invention, the link assembly 40 further includes a third link 43 and a fourth link 44 that are cross-connected to the side of the smoke collecting cylinder 20 opposite to the first link 41 and the second link 42. The first end of the third link 43 is horizontally slidably connected to the smoke collecting cylinder 20, the second end of the third link 43 is rotatably connected to the third mounting plate 113 on the stove top, the first end of the fourth link 44 is horizontally slidably connected to the stove top, and the second end of the fourth link 44 is horizontally slidably connected to the smoke collecting cylinder 20.

[0044] In this embodiment, the third link 43 and the fourth link 44 are pivotally connected by a second axial screw 35. By cross-connecting the third link 43 and the fourth link 44 to the side of the smoke collecting cylinder 20 opposite to the first link 41 and the second link 42, the support stability of the link assembly 40 for the smoke collecting cylinder 20 can be further improved. That is, the first link 41 and the second link 42 support the smoke collecting cylinder 20 on one side of the smoke collecting cylinder 20, and the third link 43 and the fourth link 44 support the smoke collecting cylinder 20 on the other side of the smoke collecting cylinder 20, reducing the deviation phenomenon of the smoke collecting cylinder 20 during the lifting process. Further, the link assembly 30 further includes a through shaft 34. The through shaft 34 is located at the bottom of the smoke collecting cylinder 20 and spans the smoke collecting cylinder 20. One end of the through shaft 34 is connected to the second end of the third link 43 at the third mounting plate 113, and the other end of the through shaft 34 is connected to the second end 412 of the first link 41 and is located within the bushing 32. By connecting the first link 41 and the third link 43 through the through shaft 34, the synchronism between the first link 41 and the third link 43 can be improved. The first link 41 drives the second link 42, and the third link 43 drives the fourth link 44, thereby improving the synchronism of the link assembly 30 and achieving the effect of stably driving the smoke collecting cylinder 20 through the link assembly 30.

[0045] Specifically, during the lifting process of the smoke collecting cylinder 20, the first link 41 drives the first end of the third link 43 and the second end of the fourth link 44 to slide horizontally on the smoke collecting cylinder 20 through the through shaft 34. At the same time, the second end of the third link 43 is driven to rotate on the stove top, and the first end of the fourth link 44 is driven to rotate on the stove top, thereby achieving the purpose of the third link 43 and the fourth link 44 lifting in the vertical direction.

[0046] Continue to refer to Figure 4 and Figure 5 According to an embodiment of the present invention, the first link 41, the second link 42, the third link 43, and the fourth link 44 are all bent rods, and the connection parts of the first link 41 and the second link 42 and the connection parts of the third link 43 and the fourth link 44 are both located at the tops of the bent rods.

[0047] In this embodiment, setting the first link 41, the second link 42, the third link 43, and the fourth link 44 as bent rods can reduce the longitudinal space of the smoke collecting cylinder 20 occupied by the first link 41, the second link 42, the third link 43, and the fourth link 44, and increase the lifting range of the smoke collecting cylinder 20. That is, the first link 41, the second link 42, the third link 43, and the fourth link 44 can be arranged at positions at the bottom of the smoke collecting cylinder 20, reducing the interference phenomenon between the first link 41, the second link 42, the third link 43, the fourth link 44 and the smoke collecting port 101 on the panel 10 during the lifting process of the smoke collecting cylinder 20.

[0048] Continue to refer to Figure 4 andFigure 5 The first end 411 of the first link 41, the second end 422 of the second link 42, the first end of the third link 43, and the second end of the fourth link 44 are in the same horizontal state, and the second end 412 of the first link 41, the first end 421 of the second link 42, the second end of the third link 43, and the first end of the fourth link 44 are in the same horizontal state.

[0049] In this embodiment, the first end 411 of the first link 41, the second end 422 of the second link 42, the first end of the third link 43, and the second end of the fourth link 44 are in the same horizontal state, and making the second end 412 of the first link 41, the first end 421 of the second link 42, the second end of the third link 43, and the first end of the fourth link 44 in the same horizontal state can improve the synchronization of the first link 41, the second link 42, the third link 43, and the fourth link 44, and improve the force uniformity of the first link 41, the second link 42, the third link 43, and the fourth link 44, reducing the phenomenon of uneven force or deviation of the first link 41, the second link 42, the third link 43, and the fourth link 44 during the lifting of the smoke collecting cylinder 20.

[0050] Continue to refer to Figure 2 According to an embodiment of the present invention, a plurality of smoke inlet holes are provided on two opposite side walls of the smoke collecting cylinder 20 corresponding to the oil fume area on the cooking range, and a grille plate (not shown in the figure) is provided at the top of the smoke collecting cylinder 20.

[0051] In this embodiment, taking the example that two gas stoves are arranged at intervals on the panel 10 of the cooking range, the smoke collecting port 101 is arranged in the area between the two gas stoves on the panel 10, and a plurality of smoke inlet holes are provided on two side walls of the smoke collecting cylinder 20 facing the two gas stoves. When the cooking range is in the working state, the fan extracts the air in the smoke collecting cylinder 20, so that a negative pressure is formed at the plurality of smoke inlet holes, and the oil fume on the cooking range enters the smoke collecting cylinder 20 through the plurality of smoke inlet holes and is discharged to the outside of the cooking range through the smoke exhaust pipe on the fan. Further, a grille plate is provided at the top of the smoke collecting cylinder 20, and the gaps between the grille plates form a flow channel for the oil fume, so that the oil fume on the cooking range can flow to the inside of the smoke collecting cylinder 20 through the gaps between the grille plates. At the same time, the plurality of grille plates can reduce the debris on the cooking range from falling into the smoke collecting cylinder 20 through the top of the smoke collecting cylinder 20.

[0052] Continue to refer to Figure 3 The smoke collecting device 100 further includes a smoke separating cover 12 provided on the inner wall of the panel 10. The smoke separating cover 12 is provided around the smoke collecting port 101 and gradually contracts towards the bottom of the cooking range to form a smoke collecting port 121.

[0053] In this embodiment, the smoke separation hood 12 is installed on the mounting plate assembly 11 around the smoke gathering port 101. A smoke gathering cavity is formed inside the smoke separation hood 12. The cooking fumes generated by the cooking range flow through the smoke gathering pipe 20 and the smoke gathering port 101 into the smoke gathering cavity of the smoke separation hood 12. The smoke separation hood 12 gradually contracts towards the bottom of the cooking range to form a smoke gathering port communicating with the blower. The cooking fumes entering the smoke gathering cavity flow through the smoke gathering port into the blower and are then discharged outside the cooking range through the exhaust pipe on the blower.

[0054] According to an embodiment of the second aspect of the present invention, the second aspect of the present invention provides a combined device with a smoke gathering device and a cooking range. The combined device with a smoke gathering device and a cooking range includes a cooking range and a smoke gathering device.
