[0002] This application claims priority to Chinese applications No. 2024217120885, filed on July 19, 2024, entitled "Oil Fume Separation and Cleaning Device, Components and Range Hood" and No. 2024118128836, filed on December 10, 2024, entitled "Oil Fume Separation and Cleaning Device, Cleaning Unit, Filter Unit Cleaning Components and Range Hood". Technical Field

[0003] This utility model relates to the field of range hood technology, specifically to an oil fume separation and cleaning device, a drive mechanism, and a range hood. Background Technology

[0004] As a core component of range hoods, the fume separator typically incorporates a multi-layered barrier structure to separate oil fumes during cooking, achieving separation through multiple interceptions of the oil-vapor mixture. Over time and with changes in cooking conditions, some grease adheres to the barrier layers of the fume separator, requiring manual removal and cleaning by the user. Existing technology includes a manufacturer designing an automatically cleaning range hood for easy filter plate cleaning. This cleaning mechanism comprises a filter cover on one side of the unit, a motor on the opposite side, a screw driven by the motor, a drive block on the screw, a support frame, a connecting frame, and a scraper. This mechanism drives the scraper to move horizontally, removing grease and debris from the filter cover and allowing it to fall into the collection trough below. However, this side-to-side scraping cleaning method is only suitable for single-layer mesh covers and is not applicable to the multi-layered fume separator mentioned in this application. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and develop an oil fume separation and cleaning device that can efficiently remove oil from oil fume separators, solve the problem of grease adhesion, and optimize the user experience.

[0006] The technical solution adopted in this patent is as follows:

[0007] An oil fume separation and cleaning device includes: one or more filter units, one or more cleaning units, and a drive mechanism; each filter unit includes one or more filter plates; each cleaning unit is configured with at least a first scraping part coupled to the air inlet side surface of each filter plate of the corresponding filter unit; the drive mechanism includes a driver, two sets of screw and nut mechanisms relatively fixedly arranged outside the one or more filter units, a synchronization component, and a rigid transmission component; the nut components of the two sets of screw and nut mechanisms are directly or indirectly connected to the one or more cleaning units through the rigid transmission component, the synchronization component drives and couples the screw components of the two sets of screw and nut mechanisms, the driver is driven and connected to the screw component of one set of screw and nut mechanisms or the synchronization component, and the driver drives the one or more cleaning units to scrape at least the air inlet side surface of each filter plate to achieve automatic cleaning.

[0008] Through the design of the cleaning unit and drive mechanism, at least the air inlet side surface of one or more filter plates can be cleaned efficiently, solving the problem of grease adhesion and optimizing the user experience. The drive mechanism drives the cleaning unit through two sets of lead screw and nut mechanisms, synchronization components, and rigid transmission components, realizing the scraping and cleaning of each filter plate by the cleaning unit. It has a simplified structure, good economy, and high synchronization and stability.

[0009] Furthermore, the one or more filter units are arranged at a lateral angle, and the driver and synchronization component are arranged above the one or more filter units. Because the oil fume separation and cleaning device of this application has a side-suction arrangement, arranging the driver and synchronization component above the filter units does not affect the airflow direction or the oil fume separation efficiency.

[0010] Another aspect of this application provides an oil fume separation and cleaning component, comprising: a panel oil filtration area and an oil fume separation and cleaning device; the panel oil filtration area is constructed in two laterally arranged panel oil filtration areas of an adsorption panel, with a partition between the two panel oil filtration areas; the oil fume separation and cleaning device includes: two filter units respectively installed inside the two panel oil filtration areas, each filter unit including one or more filter plates; two cleaning units respectively extending laterally and movably installed in the two filter units, each cleaning unit having at least one scraping part coupled to one of the following: i. at least one surface of each filter plate and the panel filter... The inner surface of the oil area; ii. at least one side surface of each filter plate; the driving mechanism, including a driver, two sets of screw and nut mechanisms fixedly arranged on the outside of the two filter units, a synchronization component and a rigid transmission component; the nut components of the two sets of screw and nut mechanisms are directly or indirectly connected to the two cleaning units through the rigid transmission component, the two ends of the synchronization component are driven and coupled to the screw components of the two sets of screw and nut mechanisms, the driver is driven and connected to the screw component of one of the sets of screw and nut mechanisms, and the driver drives the two cleaning units to scrape at least the air inlet side surface of each filter plate to achieve automatic cleaning of the oil fume separation component.

[0011] Two independent panel oil filtration areas increase the area for fumes adsorption, while the separator ensures the structural strength of the adsorption panel, preventing deformation due to airflow load and long-term stress. Each filtration unit contains multiple filter plates, with the number of layers adjustable to improve filtration efficiency. Two sets of screw-nut mechanisms, synchronization components, and rigid transmission components ensure synchronized operation of the cleaning units on both sides, guaranteeing cleaning effectiveness and reliability, and enabling automatic cleaning of the fume separation components.

[0012] Furthermore, the one or more filter units are arranged at a lateral angle, with the driver and synchronization component positioned above the oil filtration area of ​​the panel, and two sets of screw and nut mechanisms on each side positioned outside the two oil filtration areas of the panel. The upper-side layout of the driver and synchronization component optimizes the spatial adaptability of the side-suction range hood and facilitates maintenance; the external design of the screw and nut mechanisms on both sides ensures that the drive axis of the cleaning unit is parallel to the filter plate plane, reducing airflow interference and enhancing motion stability.

[0013] Furthermore, at least some filter plates in the panel oil filtration area and the oil fume separation and cleaning device are made of cold-rolled steel. More preferably, all filter plates in the panel oil filtration area and the oil fume separation and cleaning device are made of cold-rolled steel. Cold-rolled steel has high processing precision, minimal deformation, and high accuracy.

[0014] Furthermore, each filtration unit includes two or more filter plates, and each cleaning unit includes a cleaning sub-unit disposed on the front side of each filter plate. The cleaning sub-units are connected to each other by one or more first connectors. The filter plate located between two cleaning sub-units is constructed with one or more first channels that avoid the first connectors. The cleaning unit is constructed with one or more second channels that pass through the rearmost filter plate and one or more second connectors. The rigid transmission member is connected to the cleaning unit through the second connectors.

[0015] The purification efficiency is improved by using multi-layer filter plates. Each cleaning unit is equipped with multiple cleaning sub-units to ensure the cleaning effect of each filter plate. Each cleaning sub-unit is connected to a rigid transmission component through a first connector and a second connector to ensure the synchronous transmission of cleaning actions. The designed first and second channels provide ample clearance for the connection between the cleaning unit and the drive mechanism.

[0016] Another aspect of this application provides a range hood, comprising: a smoke collection section and a fan assembly, equipped with an adsorption panel and an oil fume separation and cleaning component. The adsorption panel has an oil filtration area on its planar surface, and the fan assembly generates an adsorption airflow. The technical effectiveness of the range hood is specifically demonstrated in the oil fume separation and cleaning component.

[0017] As an improvement to range hoods, the adsorption panel is arranged at an angle, which enables side-suction oil fume separation and simplifies the collection of grease after cleaning.

[0018] Furthermore, the smoke collection section has a control compartment located above the panel oil filtration area, and the driver and synchronization component are installed in the control compartment. Concentrating the driver and synchronization component in the control compartment of the smoke collection section isolates them from the filtration unit, facilitating management and maintenance.

[0019] Furthermore, it also includes an access panel located at the front of the control compartment, and a control panel for opening and closing the access panel. When inspection of the drive mechanism is required, the control panel can be disassembled to facilitate maintenance and repair of the drive and synchronization components.

[0020] This application, in another aspect, relates to a drive mechanism, including a driver, two sets of lead screw and nut mechanisms fixedly arranged opposite each other on the outside of the one or more filter units, a synchronization member, and a rigid transmission member. The synchronization member drives and couples the lead screw components of the two sets of lead screw and nut mechanisms. The driver is driven and connected to the lead screw component of one set of lead screw and nut mechanisms or the synchronization member. The nut components of the two sets of lead screw and nut mechanisms are directly or indirectly connected to one or more cleaning units of the filter unit through the rigid transmission member. The drive mechanism achieves synchronized operation of the cleaning units on both sides through the two sets of lead screw and nut mechanisms, the synchronization member, and the rigid transmission member, ensuring cleaning effect and reliability, and realizing automatic cleaning of the oil fume separation component.

[0045] The technical solution of this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0046] See Figures 1 to 8This application generally relates to an oil fume separation and cleaning device, an oil fume separation and cleaning component, a drive mechanism, a filter unit, a cleaning unit, and a range hood. In this application, "front" and "rear" generally refer to the direction of airflow from the range hood through the oil fume separation and cleaning device; the side of the panel facing the user is front, and the back is rear. Of course, within a specific component, front and rear can be defined by specific orientations.

[0047] One embodiment of the range hood involved in this application includes: a smoke collection section 6, a wind box section 7, an oil fume separation and cleaning device a, and an oil collection box 8; the smoke collection section 6 is constructed with an adsorption panel 6.1', which has two horizontally arranged panel oil filter areas 6.10'. The adsorption panel 6.1' has multiple holes or grooves forming the panel oil filter areas 6.10', allowing oil fumes to be adsorbed from these holes or grooves, while adjacent holes or grooves provide some obstruction. The wind box section 7 is equipped with a fan assembly. The oil fume separation and cleaning device a is installed inside the adsorption panel 6.1', and two filter units 2 are respectively installed behind the corresponding panel oil filter areas 6.10'. During operation, oil fumes are drawn into the panel oil filter areas 6.10' and then enter the oil fume separation and cleaning device a for oil fume separation before being discharged. (See attached image) Figure 1 In the embodiment shown, the panel oil filtration area 6.10 is composed of an array of multiple pore structures.

[0048] See Figures 1 to 5 , Figure 13 and Figure 21 The overall scheme of the oil fume separation and cleaning device a in this application includes one or more filter units 2, one or more cleaning units 3, and a drive mechanism 4; each filter unit 2 includes one or more filter plates (such as a first filter plate 2.1 and a second filter plate 2.2); each cleaning unit 3 is at least configured with a front scraper 301 coupled to the air inlet side surface of each filter plate of the corresponding filter unit 2; the drive mechanism 4 includes a driver 4.1, two sets of screw and nut mechanisms 4.2 relatively fixedly arranged on the outside of the one or more filter units 2, a synchronization member 4.3, and... Rigid transmission component 4.4; the nut component 4.21 of the two sets of lead screw and nut mechanisms 4.2 is directly or indirectly connected to the one or more cleaning units 3 through the rigid transmission component 4.4; the synchronization component 4.3 drives and couples the lead screw component 4.22 of the two sets of lead screw and nut mechanisms 4.2; the driver 4.1 is driven and connected to the lead screw component 4.22 of one set of lead screw and nut mechanisms 4.2 or the synchronization component 4.4; the driver 4.1 drives the one or more cleaning units 3 to scrape at least the air inlet side surface of each filter plate to achieve automatic cleaning of the oil fume separation component.

[0049] The oil fume separation and cleaning device a of this application, through the design of the cleaning unit 3 and the drive mechanism 4, can efficiently clean at least the air inlet side surface of one or more filter plates, solving the problem of grease adhesion and optimizing the user experience. The drive mechanism 4 drives the cleaning unit 3 through two sets of lead screw and nut mechanisms 4.2, a synchronization component 4.3, and a rigid transmission component 4.4, realizing the scraping and cleaning of each filter plate by the cleaning unit. The use of one driver 4.1 to synchronously drive the cleaning unit 3 through the two sets of lead screw and nut mechanisms 4.2 results in a simplified structure, good economy, good synchronization, and good stability.

[0050] See Figures 4 to 8 In some embodiments, one or more filter units 2 are arranged at a lateral angle, with the actuator 4.1 and synchronization member 4.3 positioned above the filter units 2, and the cleaning unit 3 initially positioned above the lead screw member 4.22. Since the oil fume separation and cleaning device of this application is suitable for a side-suction arrangement, arranging the actuator 4.1 and synchronization member 4.3 above the filter units 2 does not affect the airflow direction or oil fume separation efficiency. The initial position of the cleaning unit 3 above the lead screw member 4.22 ensures that the grease separated by the filter units 2 in the non-clean state flows downwards along the filter plate to the bottom under gravity, thus facilitating collection.

[0051] Some embodiments of the drive 4.1 include a motor 400, which is connected via a gear structure to the lead screw component 4.22 of one set of lead screw and nut mechanisms 4.2. The lead screw components 4.22 of both sets of lead screw and nut mechanisms 4.2 are vertically connected to the synchronizing component 4.3 via an intersecting shaft gear system 4.30. Figure 2 As shown, the motor 400 is connected to the lead screw component 4.22 of the lead screw and nut mechanism 4.2 on the left side.

[0052] See Figure 5The intersecting shaft gear system 4.30 includes a first bevel gear 4.301 coaxially connected to the lead screw member 4.22 of the lead screw and nut mechanism 4.2, and a second bevel gear 4.302 connected to the synchronization member 4.3. The first bevel gear 4.301 and the second bevel gear 4.302 can be one of a straight bevel gear, a helical bevel gear, a zero-degree bevel gear, or a bevel gear. The first bevel gear 4.301 and the second bevel gear 4.302 are complete gears. In other embodiments, the first bevel gear 4.301 and the second bevel gear 4.302 can be incomplete gears. This configuration allows for intermittent pushing of the cleaning unit 3, although the interval is relatively short. Due to the viscosity of grease, alternating pushing of the cleaning unit 3 can improve the cleaning effect. Furthermore, incomplete gears can also achieve a speed reduction effect, eliminating the need for an additional speed reduction mechanism.

[0053] See Figures 5 to 7 In some embodiments, the motor 400 is vertically connected to the lead screw component 4.22 of one set of lead screw and nut mechanisms 4.2 via a worm gear 4.11 and a worm wheel 4.12. With this arrangement, the extension direction of the driver 4.1 is the same as the extension direction of the upper space of one or more filter units 2. This layout reduces the height space occupied on the upper side of the one or more filter units 2, making the product structure more compact. Furthermore, the transmission connection via the worm gear 4.11 and worm wheel 4.12 can reduce speed and increase the scraping thrust on the cleaning unit 3, ensuring the reliability of the cleaning power.

[0054] Of course, in other embodiments, the driver 4.1 may be coaxially fixedly connected to the lead screw component 4.22 of one of the lead screw and nut mechanisms 4.2, such as through a coupling.

[0055] In some embodiments, the lead screw component 4.22 of the lead screw and nut mechanism 4.2 is coupled at one end to the synchronization component 4.3 via a transmission mounting base 4.3', and the intersecting shaft gear system 4.30 is installed within the transmission mounting base 4.3'. Thus, the synchronization component 4.3 and the lead screw component 4.22 form an integrated assembly, effectively avoiding installation errors and ensuring the fitting accuracy of the intersecting shaft gear system 4.30, thereby improving the stability of the scraping power of the cleaning unit 3. Specifically, the transmission mounting base 4.3' is provided with a bearing seat 4.30', and the synchronization component 4.3 and the bearing seat 4.30' are mounted via a bearing 4.31'.

[0056] See Figure 6 and Figure 8In some improvements, the synchronization component 4.3 includes a first synchronization component 4.31 and a second synchronization component 4.32. The far ends of the first synchronization component 4.31 and the second synchronization component 4.32 are respectively connected to the lead screw component 4.22 of the adjacent lead screw and nut mechanism 4.2 through intersecting shaft gear system for vertical transmission. The adjacent ends of the first synchronization component 4.31 and the second synchronization component 4.32 are connected through a coupling 4.33.

[0057] Specifically, the transmission mounting base 4.3' is provided with bearing holes 4.30', and the first synchronization component 4.31 and the second synchronization component 4.32 are mounted to the corresponding bearing holes 4.30' via bearings 4.31' respectively.

[0058] Using the above scheme, the synchronization component 4.3 and the lead screw and nut mechanism 4.2 are designed as two separate parts and then connected synchronously by the coupling 4.33, which can reduce the difficulty of installation. On the other hand, the first synchronization component 4.31 and the second synchronization component 4.32 are respectively integrated with the corresponding lead screw and nut mechanism 4.2 into a kit, which facilitates the installation of the two kits. The coupling 4.33 can be used to easily and quickly connect the two kits.

[0059] The coupling 4.33 may include two clamping members. Connecting sleeves 4.311 and 4.312, which increase friction, are respectively installed at the adjacent ends of the first synchronizing member 4.31 and the second synchronizing member 4.32. If the surface has a rough texture, the two clamping members clamp the connecting sleeves 4.311 and 4.312 with screws. The two clamping members can be locked together with screws, which allows for convenient and quick assembly.

[0060] Of course, in other embodiments, the adjacent ends of the first synchronization member 4.31 and the second synchronization member 4.32 can be constructed with positioning structures, such as square or D-shaped with positioning surfaces, or flat. The two clamping members of the coupling 4.33 are constructed with corresponding positioning structures, i.e. square or other corresponding shapes. In this way, when the two clamping members are locked, the adjacent ends of the first synchronization member 4.31 and the second synchronization member 4.32 can be connected together.

[0061] See Figures 6 to 8 In some embodiments, the worm gear 4.12 is constructed on the upper end of the corresponding lead screw member 4.22, and the driver 4.1 further includes a drive connecting seat 4.1', which is connected to the transmission mounting seat 4.3', so that the driver 4.1 is fixedly mounted relative to the transmission mounting seat 4.3'. With the above improvement, the drive connecting seat 4.1' serves to cover the worm 4.11 and the worm gear 4.12 and to mount and fix the driver 4.1.

[0062] See Figures 6 to 8In some embodiments, the drive mounting base 4.3' of the connected drive connecting seat 4.1' is configured with a first connecting flange 4.31', and the drive connecting seat 4.1' is configured with a second connecting flange 4.11'. The worm gear 4.11 and the worm wheel 4.12 are coupled at the connection point of the first connecting flange 4.31 and the second connecting flange 4.11'.

[0063] The drive connector 4.1' is axially mounted to the transmission mounting base 4.3' along the lead screw component 4.22 and fixedly connected by screws 4.12'. This design makes it very convenient to install and remove the drive 4.1, making subsequent maintenance quick and easy.

[0064] Regarding the installation of the lead screw and nut mechanism 4.2, one end of the lead screw component 4.22 can be fixed to the transmission mounting base 4.3' by one or two bearings 4.221, and the other end of the lead screw component 4.22 can be installed on the lead screw mounting base 4.22' which is fixed in a position opposite to the filter unit 2 by one or two bearings 4.221.

[0065] See Figures 1 to 15 Another specific embodiment of the oil fume separation and cleaning device a of this application includes two filter units 2, two cleaning units 3, and a drive mechanism 4; each filter unit 2 includes a first filter plate 2.1 and a second filter plate 2.2; each cleaning unit 3 is at least configured with a front scraping part 301 coupled to the air inlet side surface of each layer of filter plate of the corresponding filter unit 2; the drive mechanism 4 includes a driver 4.1, two sets of screw and nut mechanisms 4.2 relatively fixedly arranged on the outside of the two filter units 2, a synchronization member 4.3, and a rigid transmission member 4.4; the nut members 4.21 of the two sets of screw and nut mechanisms 4.2 are connected to the two cleaning units 3 through the rigid transmission member 4.4, the synchronization member 4.3 drives the screw members 4.22 of the two sets of screw and nut mechanisms 4.2, the driver 4.1 is driven to drive the screw members 4.22 of the left screw and nut mechanism 4.2, and the driver 4.1 drives the two cleaning units 3 to scrape at least the air inlet side surface of each layer of filter plate of the two filter units to achieve automatic cleaning.

[0066] By using two independent filter units 2, the area for adsorbing oil fumes can be increased, thereby improving the efficiency of oil fume adsorption and separation. At the same time, the drive mechanism 4 can ensure that the two filter units 2 are effectively cleaned.

[0067] See Figures 1 to 5 The rigid transmission component 4.4 is an integral structure with both ends extending to both sides of the filter unit 2. The rigid transmission component 4.4 is arranged on the rear side of the two filter units 2.

[0068] One embodiment of the rigid transmission component 4.4 is a square tube profile, which has high structural strength and is easy to install and position. Of course, it can also be formed by sheet metal fabrication, such as by bending the long sides to increase structural strength. In other embodiments, the rigid transmission component 4.4 can also be processed using existing processes, such as die casting or extrusion molding, and the materials can be steel, aluminum alloy, etc.

[0069] In other embodiments, the driver 4.1 may also be connected to the synchronization member 4.3 via a gear mechanism.

[0070] See Figures 9 to 15 In some embodiments, the filter unit 2 includes one or more filter plates (2.1, 2.2), and each cleaning unit 3 includes a cleaning sub-unit (3.1, 3.2) disposed on the front side and / or rear side of each filter plate (2.1, 2.2). The cleaning sub-unit (3.1, 3.2) is configured with a front scraping portion 301 and / or a rear scraping portion 302 for scraping the front side and / or rear side of each filter plate (2.1, 2.2). The shape of the front scraping portion 301 is adapted to the shape of the front side of the corresponding filter plate (2.1, 2.2), and the shape of the rear scraping portion 302 is adapted to the shape of the rear side of the corresponding filter plate (2.1, 2.2) to ensure cleaning effect.

[0071] See Figures 2 to 15 In the specific embodiment shown, the filter unit 2 includes a first filter plate 2.1 and a second filter plate 2.2. A second cleaning subunit 3.2 is disposed between adjacent first filter plates 2.1 and second filter plates 2.2. The second rear scraping part 302b of the second cleaning subunit 3.2 scrapes the rear side of the first filter plate 2.1. Of course, the second cleaning subunit 3.2 can also be configured with a second front scraping part 301b for scraping the front side of the second filter plate 2.2. The front side of the first filter plate 2.1 can be configured with the first cleaning subunit 3.1. The first front scraping part 301a of the first cleaning subunit 3.1 is used to clean the front side of the first filter plate 2.1. The first cleaning subunit 3.1 can also be configured with a first rear scraping part 302a for cleaning the rear side of the panel oil filtering area 6.10' of the cleaning adsorption panel 6.1' located on the front side of the first filter plate 2.1.

[0072] In other embodiments of the oil fume separation and cleaning device a, the cleaning subunits (3.1, 3.2) of this application can clean only the front or rear side of the adjacent filter plates (2.1, 2.2). For example, the first cleaning subunit 3.1 can be configured to clean only the front side of the first filter plate 2.1 and either the panel oil filtration area 6.10'; the second cleaning subunit 3.2 can be configured to clean only the front side of the second filter plate 2.2 and either the rear side of the first filter plate 2.1.

[0073] See Figures 9 to 15The cleaning sub-units (such as the first cleaning sub-unit 3.1 and the second cleaning sub-unit 3.2) are connected by one or more first connectors 3.3. The filter plate (such as the first filter plate 2.1) located between the two cleaning sub-units (the first cleaning sub-unit 3.1 and the second cleaning sub-unit 3.2) is constructed with one or more first channels 2.10 that avoid the first connectors 3.3, ensuring structural stability and facilitating cleaning operations. The cleaning unit 3 is constructed with one or more second connectors 3.4 that pass through one or more second channels 2.20 of the last side filter plate 2.2. The rigid transmission member 4.4 is connected to the cleaning unit 3 through the second connectors 3.4, so that the rigid transmission member 4.4 can be firmly connected to the cleaning unit, realizing the combination of transmission and cleaning functions.

[0074] For details, see Figures 9 to 15 This illustration shows a specific embodiment of the filter unit 2 and cleaning unit 3 of this application. The filter unit 2 includes two filter plates, namely a first filter plate 2.1 and a second filter plate 2.2 arranged along the airflow direction. Each cleaning unit 3 includes a first cleaning sub-unit 3.1 and a second cleaning sub-unit 3.2 disposed in front of the first filter plate 2.1 and the second filter plate 2.2. The first cleaning sub-unit 3.1 is provided with a first front scraping part 301a for cleaning the front side of the first filter plate 2.1, and the second cleaning sub-unit 3.2 is provided with a second front scraping part 301b for cleaning the front side of the second filter plate 2.2.

[0075] The first cleaning subunit 3.1 and the second cleaning subunit 3.2 are connected by one or more first connectors 3.3. The first filter plate 2.1 located between the first cleaning subunit 3.1 and the second cleaning subunit 3.2 is constructed with one or more first channels 2.10 that avoid the first connectors 3.3. The cleaning unit 3 is constructed with one or more second connectors 3.4 that pass through one or more second channels 2.20 of the last side second filter plate 2.2. The rigid transmission member 4.4 is connected to the cleaning unit 3 through the second connectors 3.4.

[0076] Figures 9 to 15 In the illustrated embodiment, three sets of first connectors 3.3 are spaced apart, and three corresponding first channels 2.10 are provided. The second filter plate 2.2 is constructed with three second channels 2.20, and the second cleaning subunit 3.2 is constructed with second connectors 3.4 passing through the three second channels 2.20. The rigid transmission member 4.4 is connected to the cleaning unit 3 through the second connectors 3.4.

[0077] In other embodiments, the first connector 3.3 may be provided in two or four or more, the first channel 2.10 may be provided in two or four or more, the second filter plate 2.2 may be constructed with two or four or more second channels 2.20, and the second cleaning subunit 3.2 may be constructed with a second connector 3.4 passing through each of the second channels 2.20.

[0078] like Figures 13 to 15 In the embodiment shown, the first connector 3.3 is a bolt assembly, and connection holes are provided on the two first cleaning subunits 3.1 and the second cleaning subunit 3.2 corresponding to the first connector 3.3.

[0079] In other embodiments, the first connector 3.3 may be a screw and a nut, wherein the nut is installed in the first cleaning subunit 3.1, such as by inlay fixing or injection molding fixing, and a corresponding connecting hole is constructed in the second cleaning subunit 3.2. The screw passes through the second cleaning subunit 3.2 and the first channel 2.10 and connects with the nut, thereby connecting the first cleaning subunit 3.1, the first filter plate 2.1 and the second cleaning subunit 3.2 into a component.

[0080] Of course, in other embodiments, the first connector 3.3 may also be a double-ended bolt, and nuts may be provided on both the first cleaning subunit 3.1 and the second cleaning subunit 3.2.

[0081] To ensure cleaning effectiveness, the first front scraper 301a is in contact with the front side of the first filter plate 2.1, and similarly, the second front scraper 301b is in contact with the front side of the second filter plate 2.2.

[0082] See Figures 13 to 15 The front scraping portion 301 is flexible to ensure cleaning effectiveness without damaging the filter unit 2. Specifically, both the first front scraping portion 301a and the second front scraping portion 301b are flexible. The front scraping portion 301 is adapted to the shape of the surface being scraped. As shown in this embodiment, the second filter plate 2.2 is constructed with multiple arc-shaped blocking portions 2.21', and filter channels 2.2' of the second filter plate 2.2 are constructed between adjacent blocking portions. The filter channels 2.2' can be spaced out as shown in the attached figure (to increase structural strength) or continuous. The second front scraping portion 301b is constructed with multiple arc-shaped protrusions adapted to its shape.

[0083] like Figures 9 to 15 In the embodiment shown, the main body (i.e. the filtration part) of the first filter plate 2.1 is a planar structure, and the filter channel 2.1' of the first filter plate 2.1 is a series of holes arranged at intervals, such as a circle. Of course, in other embodiments, it can also be other shapes, such as square, strip, etc. The side of the filter channel 2.1' is a planar blocking part 2.11'.

[0084] It should be noted that the main body of the first filter plate 2.1 can also be of other shapes, such as the second filter plate 2.2 being designed into an arc-shaped structure; of course, it can also be other existing and known suitable structures.

[0085] The first filter plate 2.1 and the second filter plate 2.2 maintain a certain distance on their air inlet sides. Specifically, a limiting part can be provided on the second filter plate 2.2 to prevent the first filter plate 2.1 from forming a gap. In other embodiments, the first filter plate 2.1 can be designed with a bent part on at least one opposite edge, which engages with the air inlet side of the second filter plate 2.2. The bent part can improve the structural strength of the first filter plate 2.1 and at the same time maintain the distance between the main body (i.e., the filtration part) of the first filter plate 2.1.

[0086] It should be emphasized that the filter channel 2.1' of the first filter plate 2.1 and the filter channel 2.2' of the second filter plate 2.2 are staggered. That is, the filter channel 2.1' corresponds to the arc-shaped blocking part 2.21' of the second filter plate 2.2, and the blocking part 2.11' corresponds to the filter port 2.2'. This can block the oil fumes multiple times and improve the separation effect.

[0087] The first filter plate 2.1 of this application is preferably made of cold plate, that is, the plate is processed at room temperature, including hole processing, such as laser cutting, which has high precision, low cost and small deformation. Of course, punching can also be used in other embodiments; the bending part 2.11 is processed, such as by bending process.

[0088] In one embodiment, the second filter plate 2.2 is die-cast.

[0089] In other embodiments, the second filter plate 2.2 may also be made of cold plate. For ease of manufacturing, the main body (i.e. the filter part) may be a planar structure.

[0090] See 9 to Figure 15 In the illustrated embodiment, the front side of the first cleaning subunit 3.1 is provided with a first rear scraper 302a for cleaning the rear side of at least the oil-filtering area 6.10' of the adsorption panel 6.1', and the front side of the second cleaning subunit 3.2 is provided with a second rear scraper 302b for cleaning the rear side of the first filter plate 2.1. The rear scraper 302 is flexible, which ensures the cleaning effect. Using the above solution allows for a more comprehensive cleaning of the oil deposits on the rear surface of the corresponding filter panel.

[0091] The adsorption panel 6.1' is typically the panel that draws in cooking fumes, located in front of the filter unit 2, and is the panel that the user can directly observe.

[0092] In other embodiments, the filter unit 2 may also include three or more filter plates, and the cleaning unit 3 may be constructed in three or more forms and arranged on the air inlet side of each filter plate. Adjacent cleaning sub-units are connected by one or more first connectors 3.3.

[0093] In other embodiments, the filter unit 2 comprises only one layer, that is, the filter unit 2 cooperates with the panel oil filtration area 6.10' to perform oil fume filtration.

[0094] See Figures 9 to 20 This application describes an embodiment of an oil fume separation and cleaning component, comprising: two laterally arranged panel oil filtration areas 6.10' and an oil fume separation and cleaning device a, wherein the panel oil filtration areas 6.10' are configured on the adsorption panel 6.1', and a partition 10' is configured between the two panel oil filtration areas 6.10'; the oil fume separation and cleaning device includes two filter units 2, two cleaning units 3, and a drive mechanism 4; the two filter units 2 are respectively installed inside the two panel oil filtration areas 6.10', and each filter unit 2 includes one or more filter plates (2.1, 2.2); the two cleaning units 3 are respectively laterally extended and movably installed on the two filter units 2, and each cleaning unit 3 is configured with at least one scraping part (301, 302) coupled to one of the following: i. at least one scraping part coupled to each of the filter plates. The inner surface of the side surface and the panel oil filtration area 6.10'; ii. at least one side surface of each filter plate; the drive mechanism 4 includes a driver 4.1, two sets of screw and nut mechanisms 4.2 fixedly arranged on the outside of the two filter units 2, a synchronization member 4.3, and a rigid transmission member 4.4; the nut members 4.21 of the two sets of screw and nut mechanisms 4.2 are directly or indirectly connected to the two cleaning units 3 through the rigid transmission member 4.4, the two ends of the synchronization member 4.3 are coupled to the screw members 4.22 of the two sets of screw and nut mechanisms 4.2, the driver 4.1 is connected to the screw member 4.22 of one of the sets of screw and nut mechanisms 4.2, and the driver 4.1 drives the two cleaning units 3 to scrape at least the air inlet side surface of each filter plate to achieve automatic cleaning of the oil fume separation component. The panel oil filtration area 6.10' is constructed with a panel filter channel 6.11', which can be a grid-like square hole as shown in the figure, or other shapes such as circular holes, strip holes, etc.

[0095] Two independent panel oil filtration areas 6.10' increase the area for fumes adsorption, while the separator 10' ensures the structural strength of the adsorption panel 6.1', preventing deformation due to airflow load and long-term stress. Each filter unit 2 contains multiple filter plates 2.1 and 2.2, with the number of layers adjustable to improve filtration efficiency. Two sets of screw-nut mechanisms 4.2, a synchronization component 4.3, and a rigid transmission component 4.4 ensure synchronized operation of the two cleaning units 3, guaranteeing cleaning effectiveness and reliability, and enabling automatic cleaning of the fume separation components.

[0096] In some embodiments, the driver 4.1 drives the two filter units 2 to scrape the surface of each filter plate at least on the air inlet side, and to clean the oil filtration area 6.10' of the panel at least on the rear side surface.

[0097] In some embodiments, one or more filter units 2 are arranged at a lateral inclination, with the driver 4.1 and synchronization member 4.3 arranged on the upper side of the panel oil filtration area 6.10', and two sets of screw and nut mechanisms 4.2 arranged on the outer sides of the two panel oil filtration areas 6.10' respectively. The upper-side arrangement of the driver 4.1 and synchronization member 4.3 optimizes the spatial adaptability of the side-suction range hood and facilitates maintenance; the external design of the screw and nut mechanisms 4.2 on both sides makes the drive axis of the cleaning unit 3 parallel to the filter plate plane, reducing airflow interference and enhancing motion stability.

[0098] Specifically Figures 9 to 15 In the illustrated embodiment, the filter unit 2 includes two filter plates, namely a first filter plate 2.1 and a second filter plate 2.2. Each cleaning unit 3 includes a first cleaning sub-unit 3.1 and a second cleaning sub-unit 3.2 disposed in front of the first filter plate 2.1 and the second filter plate 2.2. The first cleaning sub-unit 3.1 is equipped with a first front scraper 301a for cleaning the front side of the first filter plate 2.1, and the second cleaning sub-unit 3.2 is equipped with a second front scraper 301b for cleaning the front side of the second filter plate 2.2. The front side of the first cleaning sub-unit 3.1 is constructed with a first rear scraper 302a for cleaning the rear side of the oil-filtering area 6.10' of the adsorption panel 6.1', and the front side of the second cleaning sub-unit 3.2 is constructed with a second rear scraper 302b for cleaning the rear side of the first filter plate 2.1. The rear scraper 302 is flexible, which ensures the cleaning effect. Using the above solution, the oil deposits on the rear surface of the corresponding filter panel can be cleaned more comprehensively.

[0099] Other specific features of the filter unit 2 and the cleaning unit 3 can be found in the detailed description of the preceding embodiments.

[0100] See Figures 13 to 15 The first cleaning subunit 3.1 and the second cleaning subunit 3.2 are each provided with a rear scraping portion 302 and a front scraping portion 301 on their upper and lower edges, respectively, on their front and rear sides. This design allows the cleaning unit 3 to scrape away oil deposits during reciprocating movement. In other embodiments, one or more of the rear scraping portion 302 and the front scraping portion 301 may be positioned in the middle of the first cleaning subunit 3.1 and the second cleaning subunit 3.2.

[0101] See Figures 13 to 15 In one embodiment, both the first cleaning subunit 3.1 and the second cleaning subunit 3.2 are made of flexible materials, such as silicone. Of course, other known materials can also be used, including but not limited to polytetrafluoroethylene (PTFE), fluorosilicone rubber, etc.

[0102] In some embodiments, the first cleaning subunit 3.1 and the second cleaning subunit 3.2 are respectively provided with a first retaining strip 3.11 and a second retaining strip 3.21, which can be made of metal strips. This solution can improve the rigidity of the first cleaning subunit 3.1 and the second cleaning subunit 3.2. The metal strips can be made of thin steel sheets or other existing materials that meet the requirements of rigidity and a certain degree of flexibility.

[0103] The cleaning subunit 3 can be integrally molded using injection molding. The retaining strip can be positioned in the mold first and then injection molded. As described in the previous embodiment, the first retaining strip 3.11 and the second retaining strip 3.21 can be respectively installed in the molds of the first cleaning subunit 3.1 and the second cleaning subunit 3.2, and then injection molded.

[0104] See Figures 13 to 15 Another aspect of this application provides a cleaning unit including one or more cleaning sub-units 3.1, 3.2. Each cleaning sub-unit includes a first retaining strip 3.11 and a second retaining strip 3.21 constructed of a first material, and a front scraping portion 301 fixed relative to the first retaining strip 3.11 and the second retaining strip 3.21 and constructed of a second material. The front scraping portion 301 is used to couple with the air inlet side surface of the first filter plate 2.1 and the second filter plate 2.2, wherein the hardness of the first material is greater than the hardness of the second material, and the hardness of the second material is less than the hardness of the filter plates 2.1 and 2.2.

[0105] The above solution can improve the rigidity of the first cleaning subunit 3.1 and the second cleaning subunit 3.2, while also having a certain degree of flexibility, ensuring the fit between the first cleaning subunit 3.1 and the second cleaning subunit 3.2 and the first filter plate 2.1 and the second filter plate 2.2, thus guaranteeing the cleaning effect.

[0106] See Figures 16 to 20 The diagram shows the assembly state of the first smoke collection shell assembly 6.1 (or part thereof) of the smoke collection section 6 with the oil fume separation and cleaning device a. The first smoke collection shell assembly 6.1 includes a panel shell 6.11 forming its front shell and a first smoke collection shell sidewall shell 6.12 formed on the edge of the panel shell 6.11. The adsorption panel 6.1' is formed on the front side of the panel shell 6.11. The first smoke collection shell assembly 6.1 can be formed by metal stamping and / or bending. Of course, it can also be manufactured separately and then connected, such as the panel shell 6.11 and the first smoke collection shell sidewall shell 6.12 being manufactured separately and then welded together.

[0107] In one embodiment, the adsorption panel 6.1' is preferably made of cold plate, including hole processing, such as laser cutting, which has high precision, low cost and small deformation. Of course, in other embodiments, punching can also be used; the bending part 2.11 is processed, such as by bending process.

[0108] In one embodiment, the panel housing 6.11 is formed by metal stamping, and the filter channel of the panel oil filter area 6.10' is processed by laser cutting or stamping.

[0109] In one embodiment, the separating connection part 10 is a sheet metal bending part, which can be fixed to the inner side of the adsorption panel 6.1' by welding (such as spot welding), or it can be connected by other known methods, such as screws, riveting, etc.

[0110] Other features of cleaning subunits 3.1 and 3.2 can be found in other embodiments of this application.

[0111] See Figures 16 to 24 Another aspect of this application provides a range hood, comprising: a smoke collection section 6, a wind box section 7, an oil fume separation and cleaning device a, and an oil collection box 8; the smoke collection section 6 is configured with an adsorption panel 6.1', which has two horizontally arranged panel oil filtering areas 6.10'. The wind box section 7 is equipped with a fan assembly 7', the oil fume separation and cleaning device is installed inside the adsorption panel 6.1', and two filter units 2 are respectively installed inside the corresponding panel oil filtering areas 6.10'; the cleaning unit 3 is configured with a second scraper 302 for cleaning the rear surface of the panel oil filtering area 6.10', and the fan assembly 7' is used to generate an adsorption airflow; an oil collection channel 20 is configured on the lower side of the filter unit 2, and an exhaust channel 6.12' communicating with the oil channel 20 is configured on the lower side of the adsorption panel 6.1'. The oil collection box 8 is detachably mounted on the lower side of the smoke collection section 6 and communicates with the exhaust channel 6.12'. The oil collection box 8 collects the oil that has separated and settled from the filter unit 2, and at the same time collects the oil that has settled in the cleaning unit 3.

[0112] The adsorption panel 6.1' is preferably arranged at an angle, which enables side-suction oil fume separation and facilitates the collection of grease after cleaning.

[0113] See Figure 17 and Figure 18 The adsorption panel 6.1' has a first mounting part 1.1 on its upper side and a second mounting part 1.2 on its lower side. The second mounting part 1.2 has one or more positioning holes 1.21. The left and right sides have third mounting parts 1.3. The filter unit 2 has a connecting seat 2.212 on its upper side that connects to the first mounting part 1.1 and one or more positioning protrusions 2.111 on its lower side. After the filter unit 2 is assembled and positioned by the one or more positioning protrusions 2.111 and the one or more positioning holes 1.21, the connecting seat 2.212 (with connecting holes) is connected and fixed to the first mounting part 1.1 (with threaded holes) by screws, thereby realizing the installation of the filter unit 2.

[0114] The screw components 4.22 of the two sets of screw and nut mechanisms 4.2 are installed in the third mounting part 1.3, and the nut components 4.21 of the two sets of screw and nut mechanisms 4.2 are connected to the second connecting piece 3.4 of the cleaning unit 3 through the rigid transmission component 4.4.

[0115] See Figure 22 In one embodiment, the bottom of the smoke collection part 6 is provided with locking protrusions 8.3 on both sides, and the oil collection box 8 is provided with corresponding fastening grooves 8.2 at both ends. The oil collection box 8 achieves detachable connection of the bottom of the smoke collection part 6 through the fastening grooves 8.2 and locking protrusions 8.3.

[0116] See Figures 19 to 21 In some improvements, the smoke collection section 6 is located above the panel oil filter area 6.10' and has a control compartment 60. The actuator 4.1 and the synchronization component 4.3 are installed in the control compartment 60. The control compartment 60 has an access port 6.11', and a control panel e1 is installed in the access port 6.11'. The control panel e1 is detachable and used to open and close the access port 6.11'. By concentrating the actuator 4.1 and the synchronization component 4.3 in the control compartment 60 of the smoke collection section 6, the actuator 4.1 and the synchronization component 4.3 are isolated from the filter unit 2, which facilitates management and maintenance. When it is necessary to inspect the drive mechanism 4, the control panel e1 can be removed to facilitate the maintenance and repair of the actuator 4.1 and the synchronization component 4.3.

[0117] See Figure 20 The control panel e1 has several snap-fit ​​parts k1 on its inner side, and the access port 6.11' has several snap-fit ​​parts k2. The control panel e1 is detachably installed via the snap-fit ​​parts k1 and snap-fit ​​parts k2. Specifically, each snap-fit ​​part k1 has one or more laterally extending U-shaped latches k11, and the snap-fit ​​part k2 is a fastening edge constructed on the side of the access port 6.11'. The control panel e1 is installed into the access port 6.11' with a slight offset, and then pulled along one side of the snap-fit ​​part k2 to make the U-shaped latches k11 snap onto the snap-fit ​​part k2 for fixation.

[0118] The plurality of snap-fit ​​parts k1 can be sheet metal parts, the main body of the control panel e1 is made of glass material, and the plurality of snap-fit ​​parts k1 can be connected to the back side of the control panel e1 by adhesive material.

[0119] Of course, in other embodiments, the control panel e1 may also employ other existing connection structures, such as screw connections.

[0120] It should be noted that the control panel e1 also includes a control circuit e11, which is prior art and will not be described in detail in this application.

[0121] In addition, the driver 4.1 can be electrically connected to the control circuit e11. A switch control for controlling the driver 4.1 can be constructed on the control circuit e11. The control principle of the switch control is to control the driver 4.1 to start or stop. This control is an existing technology.

[0122] See Figures 16 to 23 As an improvement, the smoke collection section 6 includes a first smoke collection shell assembly 6.1 and a second smoke shell assembly 6.2. The lower part of the first smoke collection shell assembly 6.1 is rotatably connected to the second smoke shell assembly 6.2 via a hinge mechanism 8.1, and the upper part of the first smoke collection shell assembly 6.1 is detachably connected to the second smoke shell assembly 6.2. The front side of the first smoke collection shell assembly 6.1 has an adsorption panel 6.1', which has two horizontally arranged panel oil filtering areas 6.10'. The air box section 7 is connected to the second smoke shell assembly 6.2 and is equipped with a fan assembly for generating adsorption airflow. The oil fume separation and cleaning device is installed inside the adsorption panel 6.1', and two filter units 2 are respectively installed inside the corresponding panel oil filtering areas 6.10'. The cleaning unit 3 has a rear scraping part 302 for cleaning the rear surface of the panel oil filtering area 6.10'. With the above solution, the upper part of the first smoke collection shell assembly 6.1 can be disassembled and flipped open for easy maintenance of the oil fume separation and cleaning device.

[0123] The control panel e1 of the range hood is located on the upper front side of the first smoke collection housing assembly 6.1. The integration of the control panel e1 into the first smoke collection housing assembly 6.1 simplifies the structure of the second smoke housing assembly 6.2 and makes it easier to maintain the control panel e1.

[0124] The wiring port 4.15 of the driver 4.1 is electrically connected to the control circuit (not shown) of the smoke machine. The control circuit is configured with a program to control the driver 4.1. The principle of the program controlling the operation of the driver 4.1 is existing. This application applies it to the automatic cleaning of the smoke machine separation device.

[0125] In other embodiments, the cleaning unit 3 is further configured with a cleaning subunit for cleaning the outer surface of the adsorption panel 6.1', the cleaning subunit being provided with a scraping portion for cleaning the outer surface of the adsorption panel 6.1'.

[0126] Of course, the cleaning subunit can be connected to the first cleaning subunit 3.1 via a third connector, and the adsorption panel 6.1' is constructed with a third channel to avoid the third connector. Using the above solution, the separation system can be cleaned more comprehensively.

[0127] The control panel e1 of the range hood is located on the upper front side of the first smoke collection housing assembly 6.1. The integration of the control panel e1 into the first smoke collection housing assembly 6.1 simplifies the structure of the second smoke housing assembly 6.2 and makes it easier to maintain the control panel e1.

[0128] The wiring port 4.15 of the driver 4.1 is electrically connected to the control circuit e11 of the range hood. The control circuit e11 contains a program that controls the driver 4.1. The principle behind this program's control of the driver 4.1's operation is existing; this application applies it to the automatic cleaning of the range hood's separation device. Specifically, a switch control for starting the driver 4.1 can be configured on the control panel e1. Alternatively, the control circuit e11 can be configured to automatically start cleaning when the range hood is turned off after use, or it can be designed to automatically run cleaning once a certain number of weeks.
