Description

Technical Field

[0001] This utility model relates to the technical field of oil fume extraction equipment, specifically to a filter assembly and an oil fume extractor. Background Technology

[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 fumes generated during combustion and cooking, venting them outdoors. They also condense and collect the fumes, reducing pollution and purifying the air, and provide safety features such as protection against toxic substances and explosions.

[0003] The composition of cooking fumes varies depending on the cooking temperature, and most cooking fumes contain substances harmful to human health. For example, at lower cooking temperatures, the fumes mainly consist of water vapor and a small amount of volatile odor molecules; at higher cooking temperatures, the fumes mainly consist of volatile organic compounds and a small amount of fine particulate matter, such as PM2.5. PM2.5 refers to particulate matter with an aerodynamic equivalent diameter of less than or equal to 2.5 micrometers, also known as fine particulate matter or respirable particulate matter. These particles have a long residence time in the atmosphere, travel long distances, and contain various toxic and harmful substances, seriously affecting human health and the environment; when cooking temperatures are extremely high, the fumes produced in the kitchen contain a large amount of solid particulate matter and other harmful substances.

[0004] To protect users' health, range hoods typically use filters to remove cooking fumes from the kitchen, reducing the emission of harmful substances.

[0005] However, in related filtration technologies, oil and dirt accumulate on the filter screen quickly, requiring frequent cleaning, which affects the user experience, and excessive cleaning of the filter screen can shorten its lifespan. Utility Model Content

[0006] To address the aforementioned deficiencies in the prior art, this utility model provides a filter assembly and a range hood to solve at least one of the aforementioned technical deficiencies in the prior art. It can prevent the filter from accumulating grease quickly, avoid frequent cleaning of the filter, thereby extending its lifespan and improving the user experience.

[0007] A second aspect of this utility model also provides a range hood.

[0008] To achieve the objective of this utility model, this utility model provides a filter assembly, comprising:

[0009] A sliding mechanism is provided on the lower glass panel;

[0010] A filter screen is disposed on the sliding mechanism and slides relative to the lower glass panel;

[0011] An oil fume sensor, suitable for detecting PM2.5, is electrically connected to the sliding mechanism;

[0012] When the fume sensor detects PM2.5, the sliding mechanism drives the filter to slide upward relative to the lower glass panel and cover the fume inlet.

[0013] When the fume sensor does not detect PM2.5, the sliding mechanism drives the filter to slide downward relative to the lower glass panel and hide in the receiving space.

[0014] Preferably, the sliding mechanism includes a drive component, a slider, and a slide rail.

[0015] The driving component drives the slider to slide on the slide rail, which is located on the lower glass panel, and the filter screen is located on the slider.

[0016] Preferably, the filter screen is provided with activated carbon.

[0017] Preferably, it also includes an oil mesh, which is disposed on the smoke inlet.

[0018] When the filter screen covers the smoke inlet, the filter screen overlaps with the oil screen, and there is a gap between the filter screen and the oil screen.

[0019] Preferably, the oil screen has an oil screen opening, and the filter screen has a filter opening.

[0020] When the filter screen covers the smoke inlet, the oil screen opening and the filter opening are staggered.

[0021] Preferably, it also includes a processing module, which is electrically connected to the fume sensor and the driving component.

[0022] When the fume sensor detects PM2.5, it transmits a forward rotation electrical signal to the processing module, which then controls the drive component to rotate forward.

[0023] When the fume sensor does not detect PM2.5, it transmits a reversing electrical signal to the processing module, which then controls the drive component to reverse.

[0024] Preferably, the filter screen includes a first filter screen and a second filter screen arranged parallel to each other.

[0025] A filtration space is formed between the first filter screen and the second filter screen.

[0026] The second aspect of this utility model provides a range hood, including the aforementioned filter assembly, range hood body, and lower glass panel.

[0027] The range hood body has a smoke inlet, and a receiving space is formed between the lower glass panel and the range hood body. The lower glass panel is located below the smoke inlet.

[0028] The filter assembly is located on the range hood body.

[0029] Preferably, it also includes a flip panel and a motion mechanism.

[0030] The motion mechanism drives the flip panel to cover or expose the smoke inlet.

[0031] Preferably, it also includes an oil cup, which is located below the lower glass panel and the filter screen.

[0032] The beneficial effects of this utility model are as follows: The filter assembly provided by this utility model, by setting the sliding mechanism on the lower glass panel and setting the filter on the sliding mechanism, allows the filter to slide up and down relative to the lower glass panel. An oil fume sensor capable of detecting PM2.5 content is electrically connected to the sliding mechanism. When the oil fume sensor detects PM2.5, the sliding mechanism drives the filter to slide upward relative to the lower glass panel and cover the smoke inlet to filter PM2.5 in the oil fumes. When the oil fume sensor does not detect PM2.5, the sliding mechanism drives the filter to slide downward relative to the lower glass panel and hide between the lower glass panel and the range hood body, forming a space that prevents the filter from accumulating oil stains too quickly, thereby avoiding frequent cleaning of the filter, extending the filter's lifespan, and improving the user experience.

[0033] The range hood provided by this utility model, by including the aforementioned filter assembly, inevitably possesses all the advantages of that assembly. That is, the range hood can also prevent the filter from accumulating grease too quickly, thereby avoiding frequent cleaning of the filter, extending its lifespan, and improving the user experience.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] The following is combined Figures 1 to 7 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.

[0051] The range hood of this utility model includes a range hood body 1 and a lower glass panel 2. The range hood body 1 has a smoke inlet 11. The lower glass panel 2 is disposed on the range hood body 1 and located below the smoke inlet 11. An accommodating space 21 is formed between the lower glass panel 2 and the range hood body 1.

[0052] An embodiment of this utility model provides a filter assembly, which includes a sliding mechanism 100, a filter 200, and an oil fume sensor.

[0053] The sliding mechanism 100 is located on the lower glass panel 2.

[0054] The filter screen 200 is mounted on the sliding mechanism 100 and slides relative to the lower glass panel 2.

[0055] The fume sensor can detect PM2.5, and the fume sensor is electrically connected to the sliding mechanism 100.

[0056] When the fume sensor detects PM2.5, that is, when the fume sensor detects that the PM2.5 content in the fume is greater than zero, the sliding mechanism 100 drives the filter screen 200 to slide upward relative to the lower glass panel 2 and cover the fume inlet 11, which can filter the fume containing PM2.5 and avoid pollution.

[0057] When the fume sensor does not detect PM2.5, that is, when PM2.5 is filtered out or the fume itself does not contain PM2.5, i.e., the PM2.5 content in the fume is less than or equal to zero, the sliding mechanism 100 drives the filter screen 200 to slide downward relative to the lower glass panel 2 and hide in the receiving space 21. The filter screen 200 can stop the filtration operation and avoid being contaminated by the fume.

[0058] It is understood that the filter assembly provided in the embodiments of this utility model, by setting the sliding mechanism 100 on the lower glass panel 2 and setting the filter 200 on the sliding mechanism 100, allows the filter 200 to slide up and down relative to the lower glass panel 2. An oil fume sensor capable of detecting PM2.5 content is electrically connected to the sliding mechanism 100. When the oil fume sensor detects PM2.5, the sliding mechanism 100 drives the filter 200 to slide upward relative to the lower glass panel 2 and cover the smoke inlet 11 to filter PM2.5 in the oil fumes. When the oil fume sensor does not detect PM2.5, the sliding mechanism 100 drives the filter 200 to slide downward relative to the lower glass panel 2 and hide it between the lower glass panel 2 and the range hood body 1, forming an accommodating space 21. This prevents the filter 200 from accumulating oil stains too quickly, thereby avoiding frequent cleaning of the filter 200, extending the life of the filter 200, and improving the user experience.

[0059] Specifically, in combination Figure 6 In some embodiments of this utility model, the sliding mechanism 100 includes a drive member 110, a slider 120, and a slide rail 130.

[0060] The drive unit 110 drives the slider 120 to slide on the slide rail 130, which can be set on the lower glass panel 2, and the filter screen 200 can be set on the slider 120.

[0061] The fume sensor can be electrically connected to the drive unit 110, which can be a drive motor. The drive motor drives the slider 120 to slide up and down on the slide rail 130 according to the PM2.5 content detected in the fume by the fume sensor, making the structure of the filter assembly simpler and easier to operate.

[0062] When the fume sensor detects PM2.5, the drive motor rotates forward, and the filter 200 slides upward relative to the lower glass panel 2 and covers the fume inlet 11, thereby filtering the PM2.5 in the fume.

[0063] When the fume sensor does not detect PM2.5, the drive motor reverses, and the filter 200 slides downward relative to the lower glass panel 2 and is hidden in the receiving space 21 to avoid contamination of the filter 200.

[0064] In addition, in some embodiments of this utility model, the filter screen 200 is provided with activated carbon, which improves the filtration effect of the filter screen 200 on PM2.5 in the oil fume, ensures the filtration effect, and further prevents the air environment from being polluted.

[0065] Combination Figures 1 to 3 In some embodiments of this utility model, the filter assembly further includes an oil screen 300, which is disposed at the smoke inlet 11.

[0066] When the filter screen 200 covers the smoke inlet 11, the filter screen 200 overlaps with the oil screen 300 and there is a gap between them. This allows the oil fumes, after being filtered by the filter screen 200, to pass through the oil screen 300 and be filtered again by the oil screen 300, thereby improving the filtration effect of the oil fumes and further preventing oil fumes from polluting the air environment.

[0067] Furthermore, combined Figure 3 and Figure 7 In some embodiments of this utility model, the oil screen 300 is provided with an oil screen opening 310, and the filter screen 200 is provided with a filter opening 210. Both the oil screen opening 310 and the filter opening 210 can be through holes.

[0068] When the filter screen 200 covers the smoke inlet 11, the oil screen inlet 310 and the filter inlet 210 are staggered, which makes the filtration range of the oil fumes in the filter screen 200 and the oil screen 300 longer, further improving the filtration effect.

[0069] To improve the intelligence level of the filter assembly and enhance the filtration accuracy, in some embodiments of this utility model, the filter assembly further includes a processing module, which is electrically connected to the oil fume sensor and the drive unit 110.

[0070] When the fume sensor detects PM2.5, it sends a forward rotation electrical signal to the processing module. The processing module controls the drive unit 110 to rotate forward, and the slider 120 of the sliding mechanism 100 slides upward. The filter screen 200 slides upward relative to the lower glass panel 2 to cover the smoke inlet 11.

[0071] When the fume sensor does not detect PM2.5, it sends a reverse electrical signal to the processing module. The processing module controls the drive component 110 to reverse, and the slider 120 of the sliding mechanism 100 slides downward. The filter screen 200 slides downward relative to the lower glass panel 2 to expose the smoke inlet 11. The filter screen 200 also slides into the receiving space 21 formed between the lower glass panel 2 and the range hood body 1.

[0072] Combination Figure 7 In some embodiments of this utility model, the filter screen 200 includes a first filter screen 220 and a second filter screen 230 arranged in parallel with each other.

[0073] A filtration space 240 is formed between the first filter screen 220 and the second filter screen 230. Oil fumes can enter through the first filter screen 220 and be filtered for the first time. After passing through the filtration space 240, they are filtered for the second time through the second filter screen 230 and then discharged, which can further improve the filtration effect of the filter screen 200.

[0074] Combination Figures 1 to 7In an embodiment of this utility model, a range hood is also provided, which includes the above-mentioned filter assembly, range hood body 1 and lower glass panel 2.

[0075] The range hood body 1 has a smoke inlet 11, and a receiving space 21 is formed between the lower glass panel 2 and the range hood body 1. The lower glass panel 2 is located below the smoke inlet 11.

[0076] The filter assembly is located on the main body 1 of the range hood.

[0077] It is understandable that the range hood provided by this utility model, since it includes the aforementioned filter assembly, will inevitably possess all the advantages of that assembly. That is, the range hood can also prevent the filter 200 from accumulating grease too quickly, thereby avoiding frequent cleaning of the filter 200, extending its lifespan, and improving the user experience.

[0078] Furthermore, in some embodiments of this utility model, the range hood also includes a flip panel 3 and a motion mechanism 4.

[0079] The motion mechanism 4 drives the flip panel 3 to cover or expose the smoke inlet 11.

[0080] The motion mechanism 4 drives the flip panel 3 to open or close. The flip panel 3 opens automatically when the range hood is turned on and closes when the range hood is turned off.

[0081] When the range hood is needed to remove cooking fumes, the motion mechanism 4 drives the flip panel 3 to open, revealing the smoke inlet 11.

[0082] When the range hood is not needed to extract fumes, the motion mechanism 4 drives the flip panel 3 to close, covering the smoke inlet 11 and preventing the smoke inlet 11 from being contaminated by dust.

[0083] Of course, combined Figure 1 and Figure 2 In some embodiments of this utility model, the range hood also includes an oil cup 5, which is located below the lower glass panel 2 and the filter screen 200.

[0084] The oil cup 5 can collect the oil produced by the glass panel 2 and the filter screen 200, preventing the stove from being contaminated and making it easy to clean.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
