Description

Technical Field

[0001] The utility model relates to the technical field of oil fume treatment equipment, in particular to an electrostatic oil removal device and a range hood and kitchen utensil system having the same. Background Art

[0002] As a kitchen appliance for absorbing and exhausting oil fumes, range hoods occupy an important position in modern life. Oil fume purification can condense the oil fume gas into oil droplets and be collected. The general means of oil fume purification is to add an electrostatic purification device. The oil fume gas is charged by the electric field and collected by the plates. Most of the oil fume gas is condensed and collected by the electrostatic purification device. However, the plates arranged inside the existing electrostatic purification device are relatively dense. When the plates adsorb a large amount of solidified grease, the spacing between the plates will further decrease. When a large amount of oil fume needs to be discharged, the spacing between the plates is too small, which will cause the oil fume to pass through. This will affect the exhaust effect of the range hood. Utility Model Content

[0004] The first aspect of the present utility model provides an electrostatic oil removal device, including a shell, a dust collecting assembly and a driving mechanism, the interior of the shell has a communicating working area and an idle area, the shell is provided with a smoke inlet and a smoke outlet, the smoke inlet is connected to the smoke outlet through the working area, the dust collecting assembly is movably arranged in the shell, the dust collecting assembly is provided in plurality and the plurality of dust collecting assemblies are spaced apart in the working area along the length direction of the shell, and a smoke gap is formed between adjacent dust collecting assemblies, the driving mechanism can drive some of the dust collecting assemblies to move into the idle area and increase the interval between the dust collecting assemblies in the working area.

[0005] Beneficial effect: The electrostatic oil removal device of the present application sets a communicating working area and idle area inside the shell, and movably sets the dust collecting component inside the shell. When a large amount of grease is adsorbed on the dust collecting component, resulting in a smaller distance between the dust collecting components and / or an increase in the amount of oil smoke, it will cause the oil smoke to have difficulty in smoothly passing through the dust collecting component. At this time, part of the dust collecting components are driven into the idle area by the driving mechanism and the interval between the dust collecting components in the working area is increased, so that the oil smoke can pass through the gap between the dust collecting components more easily, thereby avoiding the accumulation of oil smoke at the smoke inlet and causing poor smoke exhaust.

[0006] In some embodiments, the driving mechanism can also drive the dust collecting components in the idle area to move into the working area and reduce the intervals between the dust collecting components in the working area.

[0007] Beneficial effect: When the amount of oil smoke is small, the driving mechanism drives the dust collecting components in the idle area to move into the working area and reduces the interval between the dust collecting components in the working area, so that the oil smoke can be effectively adsorbed when passing through the dust collecting components, ensuring the oil smoke adsorption effect of the electrostatic oil removal device.

[0008] In some embodiments, based on the fact that there are five dust collecting components, the idle area includes a first area located at one end of the shell; the driving mechanism includes a first driving structure, and the first driving structure and the two dust collecting components close to the first area are both transmission-connected, and the first driving structure can drive one of the two dust collecting components to move into the first area, and the other one moves toward the first area and is located in the working area.

[0009] Beneficial effect: When it is necessary to increase the spacing between the dust collecting components in the working area, the first driving structure drives one of the two dust collecting components close to the first area to move into the first area, thereby freeing up space on one side of the working area, and the other one moves toward the first area to increase the spacing between the dust collecting component and other dust collecting components, facilitating the smooth passage of a large amount of oil smoke.

[0010] In some embodiments, the idle area also includes a second area arranged at the other end of the shell, and the working area is located between the second area and the first area; the driving mechanism also includes a second driving structure, and the second driving structure and the two dust collecting components located near the second area are both transmission-connected, and the second driving structure can drive one of the two dust collecting components to move into the second area, and the other one moves toward the second area and is located in the working area.

[0012] In some embodiments, the dust collecting component has a first magnetic part, the first driving structure and / or the second driving structure has a second magnetic part, and the second magnetic part is used to be magnetically fixed to the first magnetic part.

[0013] Beneficial effect: By arranging a first magnetic part on the dust collecting component, a second magnetic part is arranged on the first driving structure and / or the second driving structure, and the second magnetic part is used to be magnetically fixed to the first magnetic part, thereby realizing magnetic fixation between the first driving structure and / or the second driving structure and the dust collecting component. The fixing and matching are carried out by magnetic attraction, and the structural setting is simple, without the need to set up additional fixing components.

[0014] In some embodiments, the first driving structure and / or the second driving structure includes a driving cylinder and a connecting rod, the driving cylinder is fixedly arranged on the shell, the driving cylinder has a telescopic rod, the telescopic direction of the telescopic rod is consistent with the length direction of the shell, the connecting rod is connected to the telescopic rod, and the connecting rod has two second magnetic parts.

[0015] Beneficial effect: The connecting rod is magnetically fixed to the two dust collecting components through two magnetic parts respectively. When the driving cylinder drives the telescopic rod to extend, the telescopic rod drives the connecting rod to move toward the first area or the second area, and then drives the two dust collecting components magnetically fixed to the connecting rod to move toward the first area or the second area, thereby increasing the interval between the dust collecting components in the working area. When the driving cylinder drives the telescopic rod to retract, the telescopic rod drives the connecting rod to move toward the working area, and then drives the two dust collecting components magnetically fixed to the connecting rod to move toward the working area, thereby reducing the interval between the dust collecting components in the working area.

[0016] In some embodiments, the shell includes a first smoke baffle, which extends along the length direction of the shell and is used to block a side of the first area facing the smoke inlet.

[0017] Beneficial effect: The setting of the first smoke baffle can block the side of the first area facing the smoke inlet, preventing the smoke from flowing to the first area, and ensuring that the smoke flows into the working area through the smoke inlet and is adsorbed by the dust collecting component in the working area before being discharged.

[0018] In some embodiments, the shell further includes a second smoke baffle, which extends along the length direction of the shell and is used to block the side of the second area facing the smoke inlet. The smoke inlet is formed between the second smoke baffle and the first smoke baffle.

[0019] Beneficial effect: The setting of the second smoke baffle can block the side of the second area facing the smoke inlet, preventing the smoke from flowing into the second area. At the same time, a smoke inlet is formed between the second smoke baffle and the first smoke baffle, ensuring that the smoke flows into the working area through the smoke inlet and is adsorbed by the dust collecting component in the working area before being discharged.

[0020] In some embodiments, slide grooves are provided on opposite side walls of the shell along the length direction of the shell, and opposite sides of the dust collecting assembly are movably disposed in the slide grooves on both sides.

[0023] Beneficial effect: When the dust collecting component moves along the slide groove, the rolling part rolls along the slide groove, thereby changing the linear friction between the dust collecting component and the slide groove into rolling friction, thereby achieving the purpose of reducing the friction resistance of the dust collecting component and avoiding the problem of the dust collecting component getting stuck.

[0024] In some embodiments, the dust collecting assembly includes a fixing frame, an electrode plate and an electrode wire, the fixing frame is movably arranged on the inner wall of the shell, the electrode plate is connected to the fixing frame, the electrode wire is connected to the fixing frame, the electrode wire and the electrode plate are spaced apart and the electrode wire is located on the side close to the smoke inlet.

[0025] Beneficial effect: When the fixed frame moves, it can drive the electrode plate and electrode wire on it to move together. When the oil smoke flows into the electrode plate through the smoke inlet, the oil smoke is ionized and charged by the electric field generated by the electrode wire. The charged oil smoke is adsorbed when passing through the electrode plate, thereby achieving adsorption and purification of the oil smoke. The adsorbed oil smoke is discharged from the electrostatic oil removal device through the smoke outlet.

[0026] In some embodiments, the electrostatic oil removal device further includes a filter assembly, which is disposed downstream of the smoke outlet.

[0027] Beneficial effect: The oil smoke discharged from the smoke outlet can be further filtered by the filter component to achieve further purification of the oil smoke. The filter component can make up for the defect that the oil smoke adsorption effect is weakened due to the reduction in the number of dust collecting components in the working area, which increases the distance between the dust collecting components.

In the idle state, the movable filter layer moves to a position avoiding the downstream of the smoke outlet; based on the increase in the interval between the dust collecting components in the working area, the movable filter layer is in the in-use state, and based on the decrease in the interval between the dust collecting components in the working area, the movable filter layer is in the idle state.

[0029] Beneficial effect: By setting the filter components in the form of a fixed filter layer and a movable filter layer, when the interval between the dust collecting components in the working area increases, the movable filter layer is in use, that is, the movable filter layer is located downstream of the smoke outlet and cooperates with the fixed filter layer to form a multi-stage filter structure to perform multi-stage adsorption and filtration of oil smoke. When the interval between the dust collecting components in the working area decreases, the movable filter layer is in idle state, that is, the movable filter layer moves to a position to avoid the downstream of the smoke outlet. At this time, the oil smoke only needs to be adsorbed and filtered by the fixed filter layer.

[0030] In some embodiments, the filter assembly further includes a support frame and a driving unit, the fixed filter layer is fixedly disposed on the support frame, the movable filter layer is movably connected to the support frame, the driving unit is disposed on the support frame, the driving unit and the movable filter layer are transmission-connected, and the driving unit is used to drive the movable filter layer to switch between the usage state and the idle state.

[0031] Beneficial effects: The support frame can support the fixed filter layer and the movable filter layer, and the driving part can drive the movable filter layer to switch between the use state and the idle state, thereby improving the switching efficiency of the movable filter layer.

[0051] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0053] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] The following combination Figures 1 to 9 , describing the embodiments of the present utility model.

[0056] like Figure 1 and Figure 2As shown, according to an embodiment of the present utility model, on the one hand, an electrostatic oil removal device is disclosed, including a shell 1, a dust collecting assembly 2 and a driving mechanism, wherein the interior of the shell 1 has a communicating working area 11 and an idle area, the shell 1 is provided with a smoke inlet 13 and a smoke outlet 14, the smoke inlet 13 is connected to the smoke outlet 14 through the working area 11, the dust collecting assembly 2 is movably arranged in the shell 1, and a plurality of dust collecting assemblies 2 are provided and the plurality of dust collecting assemblies 2 are spaced apart in the working area 11 along the length direction of the shell 1, and a smoke gap is formed between adjacent dust collecting assemblies 2, and the driving mechanism can drive some dust collecting assemblies 2 to move into the idle area and increase the interval between the dust collecting assemblies 2 in the working area 11.

[0057] The electrostatic oil removal device of the present application sets a communicating working area 11 and an idle area inside the shell 1, and movably sets the dust collecting component 2 inside the shell 1. When a large amount of grease is adsorbed on the dust collecting component 2, resulting in a smaller distance between the dust collecting components 2 and / or an increase in the amount of oil smoke, it will cause the oil smoke to have difficulty in smoothly passing through the dust collecting component 2. At this time, part of the dust collecting components 2 are driven into the idle area by the driving mechanism and the interval between the dust collecting components 2 in the working area 11 is increased, so that the oil smoke can pass through the gap between the dust collecting components 2 more easily, thereby avoiding the accumulation of oil smoke at the smoke inlet 13 and causing poor smoke exhaust.

[0058] When the amount of oil smoke is small and the intervals between the dust collecting components 2 in the working area 11 are large, the oil smoke is difficult to be effectively adsorbed by the dust collecting components 2. Based on this, in some embodiments, the driving mechanism can also drive the dust collecting components 2 in the idle area to move into the working area 11 and reduce the intervals between the dust collecting components 2 in the working area 11.

[0059] When the amount of oil smoke is small, the driving mechanism drives the dust collecting component 2 in the idle area to move into the working area 11 and reduces the interval between the dust collecting components 2 in the working area 11, so that the oil smoke can be effectively adsorbed when passing through the dust collecting component 2, ensuring the oil smoke adsorption effect of the electrostatic oil removal device.

[0060] Illustratively, the smoke inlet 13 is located at the bottom of the shell 1, and the smoke outlet 14 is located at the top of the shell 1. When the oil smoke flows from bottom to top, it flows into the working area 11 through the smoke inlet 13, is adsorbed by multiple dust collecting components 2, and then flows out through the smoke outlet 14.

[0061] In this embodiment, the shell 1 is square, and a rectangular cavity is formed inside the shell 1. The bottom and top of the square shell 1 are open to form a smoke inlet 13 and a smoke outlet 14 respectively, that is, the shell 1 is formed by a ring plate 17 surrounding it.

[0062] The dust collecting assembly 2 is vertically arranged in the shell 1, and multiple dust collecting assemblies 2 are arranged in parallel at equal intervals to achieve uniform flow of oil smoke and ensure the adsorption effect of oil smoke.

[0063] In terms of the number of settings, in this embodiment, there are 5 dust collecting components 2 and they are spaced apart along the length direction of the shell 1. The 5 dust collecting components 2 form 4 smoke gaps in the working area 11 to facilitate the passage of oil smoke, but it is not limited to this. For example, in other embodiments, the dust collecting components 2 can be set to 7 or 9, etc.

[0064] In some embodiments, there are five dust collecting components 2, the idle area includes a first area 121 located at one end of the shell 1, and the driving mechanism includes a first driving structure 3. The first driving structure 3 and the two dust collecting components 2 close to the first area 121 are all transmission-connected. The first driving structure 3 can drive one of the two dust collecting components 2 to move into the first area 121, and the other one moves toward the first area 121 and is located in the working area 11.

[0065] When it is necessary to increase the spacing between the dust collecting components 2 in the working area 11, the first driving structure 3 drives one of the two dust collecting components 2 close to the first area 121 to move into the first area 121, thereby freeing up space on one side of the working area 11, and the other one moves toward the first area 121 to increase the spacing between the dust collecting component 2 and the other dust collecting components 2, thereby facilitating the smooth passage of a large amount of oil smoke.

[0066] On the contrary, when it is necessary to reduce the spacing between the dust collecting components 2 in the working area 11, the first driving structure 3 drives the dust collecting components 2 in the first area 121 and a dust collecting component 2 close to the first area 121 to move toward the working area 11 together, thereby increasing the number of dust collecting components 2 in the working area 11 and reducing the spacing between the dust collecting components 2, thereby enhancing the adsorption capacity of oil smoke.

[0067] In some embodiments, the idle area also includes a second area 122 arranged at the other end of the shell 1, the working area 11 is located between the second area 122 and the first area 121, and the driving mechanism also includes a second driving structure, and the second driving structure and the two dust collecting components 2 located near the second area 122 are both transmission-connected, and the second driving structure can drive one of the two dust collecting components 2 to move into the second area 122, and the other moves toward the second area 122 and is located in the working area 11.

[0068] One of the two dust collecting components 2 close to the second area 122 is driven by the second driving structure to move into the second area 122, thereby further freeing up space on the other side of the working area 11, and the other one moves toward the second area 122 to increase the distance between the dust collecting component 2 and the other dust collecting components 2, thereby facilitating the smooth passage of a large amount of oil smoke.

[0069] Similarly, conversely, when it is necessary to reduce the spacing between the dust collecting components 2 in the working area 11, the second driving structure drives the dust collecting components 2 in the second area 122 and a dust collecting component 2 close to the second area 122 to move toward the working area 11 together, thereby increasing the number of dust collecting components 2 in the working area 11 and reducing the spacing between the dust collecting components 2, thereby enhancing the adsorption capacity of oil smoke.

[0070] Therefore, this embodiment can adjust the intervals between the five dust collecting components 2 in the working area 11 through the cooperation of the first drive structure 3 and the second drive structure, so that when the amount of oil smoke is large, the intervals between the dust collecting components 2 can be increased to facilitate the passage of oil smoke and avoid the problem of oil smoke gathering at the smoke inlet 13 causing poor smoke exhaust. When the amount of oil smoke is small, the intervals between the dust collecting components 2 can be reduced to ensure the adsorption effect of the dust collecting components 2 on oil smoke and avoid the problem of poor oil smoke adsorption capacity due to excessively large intervals between the dust collecting components 2.

[0071] It should be noted that one of the five dust collecting components 2 located in the middle position remains stationary. When one of the dust collecting components 2 moves into the first area 121, it drives another dust collecting component 2 to move to the connection between the first area 121 and the working area 11. When one of the dust collecting components 2 moves into the second area 122, another dust collecting component 2 moves to the connection between the second area 122 and the working area 11, thereby forming two smoke gaps between the three dust collecting components 2 in the working area 11, facilitating the passage of oil smoke. When the dust collecting component 2 in the first area 121 moves into the working area 11, the dust collecting component 2 eventually moves to the connection between the first area 121 and the working area 11. When the dust collecting component 2 in the second area 122 moves into the working area 11, the dust collecting component 2 eventually moves into the connection between the second area 122 and the working area 11, thereby forming four smoke gaps between the five dust collecting components 2 in the working area 11, facilitating the passage of oil smoke.

[0072] In some embodiments, the dust collecting assembly 2 has a first magnetic attraction portion, and the first driving structure 3 and / or the second driving structure has a second magnetic attraction portion, and the second magnetic attraction portion is used to be magnetically fixed to the first magnetic attraction portion.

[0073] By setting a first magnetic attraction part on the dust collecting component 2, a second magnetic attraction part is set on the first driving structure 3 and / or the second driving structure, and the second magnetic attraction part is used to magnetically fix with the first magnetic attraction part, thereby realizing magnetic fixation between the first driving structure 3 and / or the second driving structure and the dust collecting component 2. The fixing and matching are carried out by magnetic attraction, and the structural setting is simple, without the need to set up additional fixing components.

[0074] In this embodiment, the five dust collecting components 2 are all provided with a first magnetic attraction part, which can maintain step consistency during manufacturing and there is no need to distinguish positions during installation, simplifying the production and installation processes. The first drive structure 3 and the second drive structure are both provided with a second magnetic attraction part.

[0075] In terms of specific structure, in this application, the first drive structure 3 and the second drive structure are the same, and both are configured as linear drive mechanisms. The linear drive mechanisms are configured along the length direction of the shell 1 to drive the dust collecting assembly 2 to move into or out of the idle area along the length direction of the shell 1.

[0076] like Figures 1 to 3 、 Figure 4 As shown, in some embodiments, the first driving structure 3 and / or the second driving structure include a driving cylinder 31 and a connecting rod 32. The driving cylinder 31 is fixedly arranged on the shell 1. The driving cylinder 31 has a telescopic rod 311. The telescopic direction of the telescopic rod 311 is consistent with the length direction of the shell 1. The connecting rod 32 is connected to the telescopic rod 311, and the connecting rod 32 has two second magnetic parts.

[0077] The connecting rod 32 is magnetically fixed to the two dust collecting components 2 through two magnetic parts. When the driving cylinder 31 drives the telescopic rod 311 to extend, the telescopic rod 311 drives the connecting rod 32 to move toward the first area 121 or the second area 122, and then drives the two dust collecting components 2 magnetically fixed to the connecting rod 32 to move toward the first area 121 or the second area 122, thereby increasing the interval between the dust collecting components 2 in the working area 11. When the driving cylinder 31 drives the telescopic rod 311 to retract, the telescopic rod 311 drives the connecting rod 32 to move toward the working area 11, and then drives the two dust collecting components 2 magnetically fixed to the connecting rod 32 to move toward the working area 11, thereby reducing the interval between the dust collecting components 2 in the working area 11.

[0078] like Figure 3 As shown, in some embodiments, the housing 1 includes a first smoke baffle 15 , which extends along the length direction of the housing 1 and is used to shield the side of the first area 121 facing the smoke inlet 13 .

[0079] The setting of the first smoke baffle 15 can block the side of the first area 121 facing the smoke inlet 13, preventing the smoke from flowing to the first area 121, and ensuring that the smoke flows into the working area 11 through the smoke inlet 13 and is discharged after being adsorbed by the dust collecting component 2 in the working area 11.

[0080] In some embodiments, the shell 1 also includes a second smoke baffle 16, which extends along the length direction of the shell 1. The second smoke baffle 16 is used to block the side of the second area 122 facing the smoke inlet 13. The smoke inlet 13 is formed between the second smoke baffle 16 and the first smoke baffle 15.

[0081] The setting of the second smoke baffle 16 can block the side of the second area 122 facing the smoke inlet 13, preventing the oil smoke from flowing to the second area 122. At the same time, the smoke inlet 13 is formed between the second smoke baffle 16 and the first smoke baffle 15, ensuring that the oil smoke flows into the working area 11 through the smoke inlet 13 and is discharged after being adsorbed by the dust collecting component 2 in the working area 11.

[0082] In some embodiments, slide grooves 171 are provided on opposite side walls of the shell 1 along the length direction of the shell 1, and opposite sides of the dust collecting assembly 2 are movably disposed in the slide grooves 171 on both sides.

[0083] By setting a slide groove 171 on the inner wall of the shell 1, the dust collecting component 2 can be movably set in the slide groove 171, so that when the dust collecting component 2 moves, both sides move along the opening direction of the slide groove 171, ensuring the moving path and stability of the dust collecting component 2.

[0084] In this embodiment, two parallel sliding grooves 171 are provided on the side wall of each shell 1, and the two sides of the dust collecting component 2 are slidably engaged through the two sliding grooves 171 to improve the sliding stability of the dust collecting component 2.

[0085] In order to reduce the friction between the dust collecting component 2 and the shell 1 and improve the smoothness of movement of the dust collecting component 2, in some embodiments, a rolling portion 212 is provided on the side of the dust collecting component 2 facing the slide groove 171, and the rolling portion 212 is rotatably provided in the slide groove 171.

[0086] When the dust collecting component 2 moves along the slide groove 171, the rolling part 212 rolls along the slide groove 171, thereby changing the linear friction between the dust collecting component 2 and the slide groove 171 into rolling friction, thereby achieving the purpose of reducing the friction resistance of the dust collecting component 2 and avoiding the problem of the dust collecting component 2 getting stuck.

[0087] The rolling portion 212 may be a roller, a ball, etc., which is not specifically limited in this embodiment.

[0088] The number of rolling parts 212 and the number of chutes 171 are matched. In this embodiment, two rolling parts 212 can be set on each side of the dust collecting component 2, and the two rolling parts 212 are respectively matched with two chutes 171, but it is not limited to this. For example, when the number of chutes 171 is adjusted, the number of rolling parts 212 is also adjusted accordingly.

[0089] like Figure 2 、 Figure 4 、 Figure 6 and Figure 7As shown, in some embodiments, the dust collecting assembly 2 includes a fixing frame 21, a pole plate 22 and an electrode wire 23, wherein the fixing frame 21 is movably arranged on the inner wall of the shell 1, the pole plate 22 is connected to the fixing frame 21, the electrode wire 23 is connected to the fixing frame 21, the electrode wire 23 and the pole plate 22 are spaced apart and the electrode wire 23 is located on the side close to the smoke inlet 13.

[0090] When the fixed frame 21 moves, it can drive the electrode plate 22 and the electrode wire 23 thereon to move together. When the oil smoke flows into the electrode plate 22 through the smoke inlet 13, the oil smoke is ionized and charged by the electric field generated by the electrode wire 23. The charged oil smoke is adsorbed when passing through the electrode plate 22, thereby achieving adsorption and purification of the oil smoke. The adsorbed oil smoke is discharged from the electrostatic oil removal device through the smoke outlet 14.

[0091] The fixing frame 21 is in the shape of an elongated column and is provided with a fixing slot 211. The side portions of the electrode plate 22 are engaged in the fixing slot 211 to securely connect the electrode plate 22 and the fixing frame 21. Specifically, each electrode plate 22 is provided with two fixing frames 21, which secure the two sides of the electrode plate 22 together. Each fixing frame 21 is provided with two corresponding rolling portions 212, and each fixing frame 21 engages with the two chute 171 via the two rolling portions 212.

[0092] It should be noted that the principle of adsorption of the oil pressure by the electrode wire 23 and the electrode plate 22 is a prior art and will not be described in detail in this embodiment.

[0093] Since the number of dust collecting components 2 remaining in the working area 11 is reduced, the intervals between the dust collecting components 2 in the working area 11 are increased. In order to overcome the defect of weakened adsorption effect of oil smoke caused by the reduction in the number of dust collecting components 2, as shown in FIG. Figure 8 and Figure 9 As shown, in some embodiments, the electrostatic oil removal device further includes a filter assembly 4 , which is disposed downstream of the smoke outlet 14 .

[0094] The oil smoke discharged from the smoke outlet 14 can be further filtered by the filter component to achieve further purification of the oil smoke. The filter component 4 can make up for the defect that the working area 11 has a weakened oil smoke adsorption effect due to the reduction in the number of dust collecting components 2 and the increase in the intervals between the dust collecting components 2.

[0095] In some embodiments, the filter component 4 includes a fixed filter layer 41 and a movable filter layer 42, wherein the fixed filter layer 41 is fixedly arranged downstream of the smoke outlet 14, and the movable filter layer 42 has an in-use state and an idle state. In the in-use state, the movable filter layer 42 is located downstream of the smoke outlet 14 and cooperates with the fixed filter layer 41 to form a multi-stage filtering structure. In the idle state, the movable filter layer 42 moves to a position to avoid the downstream of the smoke outlet 14, the interval between the dust collecting components 2 based on the working area 11 increases, and the movable filter layer 42 is in the in-use state. The interval between the dust collecting components 2 based on the working area 11 decreases, and the movable filter layer 42 is in the idle state.

[0096] By setting the filter component 4 in the form of a fixed filter layer 41 and a movable filter layer 42, when the interval between the dust collecting components 2 in the working area 11 increases, the movable filter layer 42 is in use, that is, the movable filter layer 42 is located downstream of the smoke outlet 14 and cooperates with the fixed filter layer 41 to form a multi-stage filter structure to perform multi-stage adsorption filtration on the oil smoke. When the interval between the dust collecting components 2 in the working area 11 decreases, the movable filter layer 42 is in an idle state, that is, the movable filter layer 42 moves to a position to avoid the downstream of the smoke outlet 14. At this time, the oil smoke only needs to be adsorbed and filtered by the fixed filter layer.

[0097] In some embodiments, the filter assembly 4 also includes a support frame 43 and a driving unit, the fixed filter layer 41 is fixedly set on the support frame 43, the movable filter layer 42 is movably connected to the support frame 43, the driving unit is set on the support frame 43, the driving unit and the movable filter layer 42 are transmission-connected, and the driving unit is used to drive the movable filter layer 42 to switch between the use state and the idle state.

[0098] The support frame 43 can support the fixed filter layer 41 and the movable filter layer 42 , and the driving unit can drive the movable filter layer 42 to switch between the use state and the idle state, thereby improving the switching efficiency of the movable filter layer 42 .

[0099] In some embodiments, the movable filter layer 42 can be rotatably connected to the support frame 43, and the driving part can be a rotary driving part (such as a rotary cylinder), which drives the movable filter layer 42 to rotate relative to the support frame 43 through the rotary driving part, thereby realizing the switching of the movable filter layer 42 between the use state and the idle state.

[0100] In other embodiments, the movable filter layer 42 can be slidably connected to the support frame 43, and the driving part can be a linear driving part (such as a linear cylinder), which drives the movable filter layer 42 to slide relative to the support frame 43 through the linear driving part, thereby realizing the switching of the movable filter layer 42 between the use state and the idle state.

[0101] The fixed filter layer 41 and the movable filter layer 42 are specifically oil filter nets. The fixed filter layer 41 may have one or more layers of oil filter nets, and the movable filter layer 42 may also have one or more layers of oil filter nets.

[0102] In terms of the setting position, the movable filter layer 42 can be set upstream or downstream of the fixed filter layer 41, and this embodiment does not impose any limitation.

[0103] For example, the support frame 43 has a smoke passage, which is connected to the smoke outlet 14, the fixed filter layer 41 is fixedly arranged in the smoke passage, the side wall of the smoke passage is provided with an opening 431, the movable filter layer 42 is slidably arranged in the guide groove 432 on the inner wall of the smoke passage, and the movable filter layer 42 can slide along the guide groove 432 and switch between the use position and the idle position through the opening 431.

[0104] To facilitate understanding of the electrostatic oil removal device of this embodiment, its working principle is introduced as follows:

[0105] The oil smoke flows into the working area 11 through the smoke inlet 13, and is first ionized by the electric field generated by the electrode wire 23. The ionized oil smoke carries the charge and flows into the gap between the electrode plates 22. The oil smoke is adsorbed and filtered by the multiple electrode plates 22. The treated oil smoke flows out through the smoke outlet 14 and is filtered and purified again by the filter component 4.

[0106] When the amount of oil smoke increases and / or too much grease is adsorbed on the dust collecting components 2, resulting in a smaller distance between the dust collecting components 2, the first driving structure 3 drives one of the two dust collecting components 2 close to the first area 121 to move into the first area 121, thereby further freeing up space on one side of the working area 11, and the other one moves toward the first area 121 and eventually moves to the connection between the first area 121 and the working area 11. The second driving structure drives one of the two dust collecting components 2 close to the second area 122 to move into the second area 122, thereby further freeing up space on the other side of the working area 11, and the other one moves toward the second area 122 and eventually moves to the connection between the first area 121 and the working area 11, so that the three dust collecting components 2 in the working area 11 form two smoke gaps, facilitating the smooth passage of a large amount of oil smoke;

[0107] At the same time, the driving unit drives the movable filter layer 42 to switch to the use state, that is, the movable filter layer 42 is located downstream of the smoke outlet 14 and the movable filter layer 42 and the fixed filter layer 41 cooperate to form a multi-stage filtering structure, which further filters and purifies the oil smoke flowing out of the smoke outlet 14 in multiple stages.

[0108] When the amount of oil smoke decreases and the spacing between the dust collecting components 2 in the working area 11 needs to be reduced, the first driving structure 3 drives the dust collecting component 2 in the first area 121 and a dust collecting component 2 close to the first area 121 to move toward the working area 11 together, and the second driving structure drives the dust collecting component 2 in the second area 122 and a dust collecting component 2 close to the second area 122 to move toward the working area 11 together, thereby increasing the number of dust collecting components 2 in the working area 11, so that the five dust collecting components 2 in the working area 11 form four smoke gaps to reduce the spacing between the dust collecting components 2 and enhance the adsorption capacity of oil smoke.

[0109] At the same time, the driving unit drives the movable filter layer 42 to switch to the idle state, that is, the movable filter layer 42 moves to a position away from the downstream of the smoke outlet 14. At this time, the oil smoke flowing out of the smoke outlet 14 only needs to be adsorbed and filtered by the fixed filter layer 41.
