[0002] A range hood, also known as a kitchen exhaust hood, is a kitchen appliance that purifies the kitchen environment by exhausting cooking fumes from indoors to outdoors. It typically consists of a smoke collection chamber and a casing assembly. Range hoods are generally installed above the kitchen stove and quickly remove harmful cooking fumes or waste products from combustion, venting them outdoors. They also condense and collect the fumes, reducing pollution and purifying the air.

[0003] Range hoods typically consist of a smoke collection chamber and a casing assembly. To prevent cooking fumes from being directly discharged into the environment and causing pollution, a grease filter is usually installed at the smoke inlet. When the range hood is working, cooking fumes from the kitchen enter the hood through the smoke inlet and are then discharged through the duct. As the range hood is used over time, grease accumulates on the grease filter at the smoke inlet, requiring regular cleaning.

[0055] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0056] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0058] The following is combined Figures 1 to 11 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0059] Combination Figures 1 to 11 The present invention provides an automatic oil filter cleaning component, which is installed on a range hood. The range hood is equipped with an oil filter and an oil cup, with the oil cup located below the oil filter. The oil filter includes a first layer of oil filter 1, a second layer of oil filter 2, and a third layer of oil filter 3.

[0060] The first layer of oil mesh 1 is provided with a first air inlet slot 11, the second layer of oil mesh 2 is provided with a second air inlet slot 21, and the third layer of oil mesh 3 is provided with an air outlet slot 31. The first layer of oil mesh 1, the second layer of oil mesh 2, and the third layer of oil mesh 3 are sequentially staggered and interlocked to form an oil mesh filtration area. The first layer of oil mesh 1, the second layer of oil mesh 2, and the third layer of oil mesh 3 can be fixed by interlocking with the outer connecting edge and the inner connecting edge.

[0061] In this embodiment, the second layer of oil mesh 2 can be integrally die-cast. A protruding fastener 22 is also provided below the second layer of oil mesh 2, so that the second layer of oil mesh 2 can be installed in conjunction with the first layer of oil mesh 1 through the protruding fastener 22, which facilitates the installation and disassembly of the first layer of oil mesh 1 and the second layer of oil mesh 2.

[0062] The first air inlet slot 11 and the second air inlet slot 21 are staggered with each other, and the air outlet slot 31 is staggered with the second air inlet slot 21. The staggered arrangement changes the direction of the oil fume entry, thereby increasing the turbulence effect and improving the filtration effect.

[0063] The automatic oil cleaning assembly includes a scraper mechanism 100, a drive mechanism 200, and a guide mechanism 300.

[0064] The scraper mechanism 100 includes a scraper 110, which is connected to the first layer of oil mesh 1 in a scraping action.

[0065] The drive mechanism 200 includes a drive member 210 and a slider 220, wherein the drive member 210 drives the slider 220 to slide along a first direction.

[0066] The guiding mechanism 300 includes a guide rail 310 and a guide slider 320. The guide rail 310 is disposed on the second layer of oil mesh 2, and the guide slider 320 is slidably connected to the guide rail 310 along a first direction. The scraper 110 is connected to the guide slider 320, and the sliding member 220 is connected to the guide slider 320, so that the driving member 210 can drive the scraper 110 to slide and scrape along the first layer of oil mesh 1 in the first direction. The scraper 110 slides on the first layer of oil mesh 1 and forms a squeezing force on the surface of the first layer of oil mesh 1, which can repeatedly scrape and wash the oil stains and grease on the first layer of oil mesh 1, thereby ensuring that the first layer of oil mesh 1 is clean and tidy. An oil guide hole is also provided at the bottom of the first layer of oil mesh 1, and the oil stains and grease scraped by the scraper 110 can flow into the oil cup through the oil guide hole to realize the automatic cleaning of the oil mesh.

[0067] It should be noted that the first direction in this embodiment can be a vertical direction. The length direction of the first air inlet groove 11 of the first layer of oil mesh 1 is parallel to the first direction, that is, the length direction of the first air inlet groove 11 can also be vertical. When the scraper 110 scrapes and washes the oil stains and grease on the first layer of oil mesh 1, the oil stains and grease can flow into the oil cup through the oil guide hole in the vertical direction under the action of gravity.

[0068] It is understood that the automatic oil screen cleaning assembly provided in the embodiments of this utility model, by setting up a scraper mechanism 100 with a scraper 110, a drive mechanism 200 with a drive member 210 and a sliding member 220, and a guide mechanism 300 with a guide rail 310 and a guide slider 320; the scraper 110 is connected to the first layer of oil screen 1 in a scraping engagement, and the drive member 210 drives the sliding member 220 to slide along a first direction; moreover, the guide rail 310 is set on the second layer of oil screen 2, the guide slider 320 is slidably connected to the guide rail 310 along the first direction, the scraper 110 is connected to the guide slider 320, the sliding member 220 is connected to the guide slider 320, and the drive member 210 drives the scraper 110 to slide and scrape along the first direction of the first layer of oil screen 1, so that the scraper 110 can scrape and wash the oil stains on the first layer of oil screen 1, so that the oil screen can be cleaned without relying on manual disassembly, making the operation more convenient, the cleaning efficiency higher, and the cleaning effect better.

[0069] Specifically, in combination Figure 3 and Figure 8 In some embodiments of this utility model, the driving component 210 includes a driving motor 211, a driving gear 212, and a driving lead screw 213.

[0070] In this configuration, the sliding member 220 is helically connected to the drive screw 213, which is rotatably connected to the first layer of oil mesh 1. A drive gear 212 is mounted on the output shaft of the drive motor 211 and meshes with one end of the drive screw 213. The drive motor 211 drives the drive screw 213 to rotate, allowing the sliding member 220 to move along the axial direction of the drive screw 213. In other words, the axial direction of the drive screw 213 can be parallel to the first direction, meaning the drive screw 213 can also be vertically oriented, allowing the sliding member 220 to move vertically.

[0071] Using a drive screw 213 to drive the movement of the slider 220 can make the movement of the slider 220 more stable, which in turn makes the sliding of the guide slider 320 more stable, thereby ensuring the scraping stability of the scraper 110 on the first layer of oil mesh 1 and further improving the cleaning degree of scraping.

[0072] Combination Figure 3 , Figure 8 and Figure 9 In some embodiments of this utility model, the drive mechanism 200 further includes a motor bracket 230 and a bearing seat 240.

[0073] The motor bracket 230 is located between the first layer of oil mesh 1 and the second layer of oil mesh 2, and the drive motor 211 is mounted on the motor bracket 230.

[0074] A bearing housing 240 is disposed on the first layer of oil mesh 1, and a drive screw 213 is rotatably connected to the bearing housing 240. In this embodiment, the bearing housing 240 may include a first bearing housing 241 and a second bearing housing 242. The first bearing housing 241 is fixed to the bottom of the first layer of oil mesh 1, and the second bearing housing 242 is fixed to the top of the first layer of oil mesh 1. The first end of the drive screw 213 is rotatably connected to the first bearing housing 241, and the second end of the drive screw 213 is rotatably connected to the second bearing housing 242, making the drive output of the drive mechanism 200 more stable.

[0075] The drive gear 212 can be a bevel gear, which makes the transmission efficiency of the drive motor 211 to the drive screw 213 higher and the load-bearing capacity stronger, thereby ensuring the stability of the oil screen scraping.

[0076] In addition, combined Figure 3 and Figure 10 In order to further improve the sliding motion stability of the guide slider 320 and ensure the scraping motion stability and scraping effect of the scraper 110 on the first layer of oil mesh 1, in some embodiments of this utility model, the guide rail 310 in the guide mechanism 300 includes a first guide rail 311 and a second guide rail 312 arranged in parallel with each other, and the guide slider 320 includes a first guide slider 321 and a second guide slider 322.

[0077] The first guide rail 311 and the second guide rail 312 are both parallel to the first direction and are both arranged on the second layer of oil mesh 2. The length direction of the second air inlet groove 21 in the second layer of oil mesh 2 is parallel to the first direction, that is, the length direction of the second air inlet groove 21 can be arranged in the vertical direction. At this time, the first guide rail 311 and the second guide rail 312 can be arranged in the vertical direction on both sides of the second layer of oil mesh 2.

[0078] The first guide slider 321 is slidably connected to the first guide rail 311, and the second guide slider 322 is slidably connected to the second guide rail 312.

[0079] The first end of the scraper 110 is connected to the first guide slider 321, and the second end of the scraper 110 is connected to the second guide slider 322. Both the first guide slider 321 and the second guide slider 322 are connected to the sliding member 220. When the drive motor 211 drives the sliding member 220 to move in the vertical direction, the first guide slider 321 and the second guide slider 322 also move in the vertical direction, thereby causing the scraper 110 to also perform scraping and washing motion on the first layer of oil mesh 1 in the vertical direction.

[0080] Of course, combined Figure 3 , Figure 6 and Figure 10In order to ensure the synchronization of the movement of the first guide slider 321 and the second guide slider 322 along the first direction (i.e., the vertical direction), thereby further improving the movement stability and load-bearing capacity of the guide slider 320, in some embodiments of this utility model, the guide mechanism 300 also includes a guide bracket 330.

[0081] The first guide slider 321 is fixed at the first end of the guide bracket 330, and the second guide slider 322 is fixed at the second end of the guide bracket 330.

[0082] The scraper 110 is mounted on the guide bracket 330, and the slider 220 is connected to the guide bracket 330. When the drive motor 211 drives the slider 220 to move in the vertical direction, the guide bracket 330 can also move in the first direction (i.e., the vertical direction), thereby driving the first guide slider 321 and the second guide slider 322 to move in the vertical direction at the same time.

[0083] Combination Figure 3 and Figure 11 In some embodiments of this utility model, the scraper mechanism 100 further includes a scraper bracket 120.

[0084] The scraper 110 is mounted on the scraper bracket 120, which is detachably mounted on the guide bracket 330. For example, the scraper bracket 120 can be fixed to the guide bracket 330 with screws, facilitating its installation and removal. When the guide bracket 330 moves in the first direction, the scraper bracket 120 can drive the scraper 110 to move in the first direction. The scraper bracket 120 provides greater stability when the scraper 110 scrapes the first layer of oil mesh 1.

[0085] Combination Figure 11 In some embodiments of this utility model, the scraper 110 includes a fixing strip 111 and a plurality of scraper elements 112.

[0086] Each scraper 112 is evenly distributed on the fixing strip 111, which is set on the scraper support 120. The first layer of oil mesh 1 is provided with multiple first air inlet slots 11, and the length direction of each first air inlet slot 11 is parallel to the first direction.

[0087] Each scraper 112 is matched and scraped in connection with each first air inlet groove 11. For example, a recess is formed between each first air inlet groove 11, and a gap can be formed between each scraper 112, so that each scraper 112 can be inserted into the recess between each first air inlet groove 11, so that the scraper 112 can conform to the surface of the first layer of oil mesh 1, and can also conform to the first air inlet groove 11, thereby enabling the scraper 112 to more thoroughly scrape and clean the oil mesh.

[0088] In addition, combined Figure 11In some embodiments of this utility model, the scraper mechanism 100 further includes a fixing frame 130.

[0089] The fixing frame 130 includes a support plate 131 and a plurality of support columns 132, each support column 132 being evenly arranged on the support plate 131, and each scraper 112 being matched with each support column 132.

[0090] When the scraper 110 is installed in the fixed frame 130, each scraper piece 112 is fitted onto each support column 132, and the support plate 131 is installed in the scraper bracket 120. After the scraper piece 112 has been repeatedly scraping and cleaning the oil screen for a long time, and the scraper piece 110 has hardened or aged, it can be replaced more easily.

[0091] Each support column 132 of the fixed frame 130 can support each scraper 112, so that when each scraper 112 scrapes the first layer of oil mesh 1, the scraper 112 and the first layer of oil mesh 1 can make better and more stable contact with each other, with a larger contact area, thereby improving the scraping efficiency.

[0092] Specifically, in some embodiments of this utility model, the scraper 112 can be made of a soft material, such as soft silicone or rubber, which improves the effect of scraping and cleaning the oil screen and also prevents the oil screen from being damaged.

[0093] Combination Figures 1 to 11 In an embodiment of this utility model, a range hood is also provided, which includes the above-mentioned automatic oil filter cleaning assembly, range hood body and oil filter.

[0094] The oil filter is located on the main body of the range hood, and the automatic oil filter cleaning component is located on the oil filter.

[0095] It is understandable that the range hood provided by this utility model, since it includes the aforementioned automatic oil filter cleaning component, will inevitably possess all the advantages of that component. That is, this range hood also allows for oil filter cleaning without relying on manual disassembly, making operation more convenient, cleaning efficiency higher, and cleaning effect better.
