Description

Technical Field

[0001] This application relates to the field of kitchen equipment technology, and in particular to a filter installation structure for cooking utensils. Background Technology

[0002] Range hoods are cooking appliances used in kitchens to purify the cooking environment. They use a built-in impeller to generate negative pressure suction, which draws in cooking fumes, odors, and high-temperature gases produced during cooking. After the grease is separated by a filter, the fumes are discharged outdoors or purified and circulated, effectively improving the air quality in the kitchen.

[0003] In related technologies, the filter installation structure includes a housing and a filter screen. The housing is provided with an air duct opening, and the filter screen is equipped with a magnetic strip. The filter screen and the air duct opening are detachably connected by magnetic attraction between the magnetic strip and the housing, which facilitates regular disassembly, cleaning and maintenance of the filter screen.

[0004] However, during actual installation, since the magnetic strip can be attracted to any position on the housing, the attraction position of the magnetic strip and the housing may deviate, making it impossible for the filter screen to be completely aligned with the air duct opening, which makes it inconvenient to install the filter screen. Utility Model Content

[0005] This application provides a cooking appliance filter installation structure to solve the technical problem in related technologies where the filter is magnetically attracted to the housing via a magnetic strip, resulting in the filter not being fully aligned with the air duct opening, thus making filter installation inconvenient.

[0006] In a first aspect, embodiments of this application provide a cooking utensil strainer installation structure, including:

[0007] A housing, wherein an air duct is provided inside the housing;

[0008] Filter screen;

[0009] The alignment component is used to align the filter screen with the air duct opening during the installation of the filter screen, so that the positions of the filter screen and the air duct opening correspond and match.

[0010] A magnetic suction assembly is used to magnetically fix the filter screen to the front end of the air duct opening. The filter screen can be attracted to or detached from the air duct opening through the magnetic suction assembly.

[0011] In some embodiments, the magnetic suction component is disposed on the edge of the filter or the outer periphery of the air duct opening. When the filter is magnetically fixed to the front end of the air duct opening, the magnetic suction component is located on the outer periphery of the air duct opening or the edge of the filter.

[0012] In some embodiments, the magnetic component includes a magnetic element disposed at the edge of the filter or on the outer periphery of the air duct opening, and the filter can be attracted to or detached from the air duct opening by the magnetic element.

[0013] In some embodiments, the magnetic attraction component includes:

[0014] A first magnetic element is connected to one side of the filter screen;

[0015] The cooking utensil filter installation structure also includes:

[0016] The first adsorption element is provided on the housing corresponding to the first magnetic element. The first magnetic element is used to magnetically attract or detach from the first adsorption element. The filter screen can be attracted or detached from the air duct opening through the first magnetic element and the first adsorption element.

[0017] In some embodiments, the magnetic attraction component further includes:

[0018] The second magnetic element is disposed on at least one of the opposite sides of the filter screen;

[0019] The cooking utensil filter installation structure also includes:

[0020] The second adsorption element is provided on the housing corresponding to the second magnetic element. The second magnetic element is used to magnetically attract or detach from the second adsorption element. The filter screen can be attracted to or detached from the air duct opening through the second magnetic element and the second adsorption element.

[0021] In some embodiments, the filter screen includes a filtering portion and a connecting portion. The connecting portion is arranged circumferentially along the filtering portion. The first magnetic element and the second magnetic element are both disposed on the connecting portion. The side of the connecting portion opposite to the first magnetic element is configured as a magnetic portion. The area on the housing corresponding to the magnetic portion is configured as an adsorption area. The magnetic portion is used to magnetically attract or detach from the adsorption area. The filter screen can be attracted to or detached from the air duct opening through the magnetic portion and the adsorption area.

[0022] In some embodiments, the magnetic force of the first magnetic element is greater than the magnetic force of the second magnetic element, and / or the magnetic force of the second magnetic element is greater than the magnetic force of the magnetic portion.

[0023] In some embodiments, the first magnetic element is a neodymium iron boron magnetic strip, and the first adsorption element is an electroplated pure iron layer.

[0024] In some embodiments, the second magnetic element is a ferrite magnetic strip, and the second adsorption element is an iron-nickel plated alloy.

[0025] In some embodiments, the magnetic part is a magnetically conductive stainless steel sheet, and the adsorption area is a steel plate.

[0026] In some embodiments, the alignment component includes a snap-fit ​​part and a snap fastener. The snap-fit ​​part is disposed on the air duct opening, and the snap fastener is disposed on the filter screen. The snap fastener engages or disengages from the snap-fit ​​part to drive the filter screen and the air duct opening to be fixed or detached.

[0027] This application provides a cooking appliance filter installation structure. By employing an alignment component, the filter can be aligned with the air duct opening, preventing positional misalignment during installation. Aligning the filter with the air duct opening prevents unfiltered air from entering the housing through the gap between the filter and the air duct opening, thus preventing oil fumes from affecting other components inside the cooking appliance. Furthermore, users do not need to repeatedly adjust the filter's position, facilitating filter installation. The combination of the alignment component and the magnetic component provides a convenient and simple magnetic fixation method, improving the efficiency of filter installation and removal and enhancing the fixation strength of the filter to the air duct opening, preventing the filter from detaching from the air duct opening during use.

[0042] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] In related technologies, the filter installation structure includes a housing and a filter. The housing has an air duct as a fume channel, and the filter has a magnetic strip. This magnetic design simplifies the installation process. The filter can be detachably connected to the air duct by magnetic attraction between the magnetic strip and the metal surface of the housing. This makes it easy for users to regularly disassemble, clean, and maintain the equipment, ensuring long-term efficient operation.

[0045] However, during actual installation, since the magnetic strip can be attracted to any position on the housing, when the magnetic strip is deviated from its position, the filter screen can still be fixed to the housing, but the position of the filter screen will shift accordingly. This will eventually cause the filter screen and the air duct to not be completely aligned, causing some air to pass through the gap between the filter screen and the air duct, which cannot be effectively filtered by the filter screen, thus causing the oil fumes to affect the internal components of the range hood.

[0046] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0047] Combination Figures 1 to 4This application provides a cooking utensil strainer installation structure, including:

[0048] The housing 100 has an air duct 110 inside it;

[0049] Filter size 200;

[0050] The alignment component 300 is used to align the filter 200 with the air duct 110 during filter installation, so that the positions of the filter 200 and the air duct 110 correspond and match.

[0051] The magnetic assembly 400 is used to magnetically fix the filter 200 to the front end of the air duct 110. The filter 200 can be attracted to or detached from the air duct 110 through the magnetic assembly 400.

[0052] In this application, by employing the alignment component 300, the alignment component 300 can align the filter 200 with the air duct 110, thereby preventing positional misalignment of the filter 200 and the air duct 110 during installation. By aligning the filter 200 with the air duct 110, some unfiltered air is prevented from entering the housing 100 along the gap between the filter 200 and the air duct 110, thereby preventing oil fumes from affecting other components inside the cooking equipment. Furthermore, the user does not need to adjust the position of the filter 200 multiple times, thus facilitating the installation of the filter 200. By employing the alignment component 300 and the magnetic component 400, the magnetic fixing method is convenient and simple, improving the efficiency of the user in disassembling and assembling the filter 200, and increasing the fixing strength of the filter 200 to the air duct 110, preventing the filter 200 from detaching from the air duct 110 during use of the cooking equipment.

[0053] In this embodiment, the corresponding matching of the filter screen 200 and the air duct 110 means that the four sides of the filter screen 200 and the four sides of the air duct 110 maintain a uniform margin, so that the oil fumes will not leak out along the gap between the filter screen 200 and the air duct 110. For example, the distance between the upper part of the filter screen 200 and the upper part of the air duct 110 is the same as the distance between the lower part of the filter screen 200 and the lower part of the air duct 110.

[0054] In this embodiment, the air duct 110 is rectangular, and the filter 200 is configured to cooperate with the rectangular air duct 110. The area of ​​the filter 200 is larger than the area of ​​the air duct 110. When the filter 200 is fixed to the housing 100, the filter 200 can further block the air duct 110, thereby improving the filtration efficiency of oil fumes.

[0055] In other embodiments, the shapes of the air duct 110 and the filter 200 can be adapted as needed. For example, the air duct 110 can be set to a circle, in which case the filter 200 can be rectangular or circular.

[0056] In this embodiment, the filter holes on the filter screen 200 are diamond-shaped. In other embodiments, the filter holes on the filter screen 200 can be adjusted as needed, for example, the filter holes can be set as circular, square or strip-shaped holes.

[0057] The magnetic suction component 400 is disposed on the edge of the filter 200 or the outer periphery of the air duct 110. When the filter 200 is magnetically fixed to the front end of the air duct 110, the magnetic suction component 400 is located on the outer periphery of the air duct 110 or the edge of the filter 200.

[0058] In this embodiment, the magnetic suction component 400 is disposed on the edge of the filter screen 200. When the filter screen 200 is magnetically fixed to the front end of the air duct opening 110, the magnetic suction component 400 is located on the outer periphery of the air duct opening 110. By aligning the magnetic suction component 400 with the outer periphery of the air duct opening 110, the arrangement range of the magnetic suction component 400 is increased, thereby indirectly improving the fixing strength between the filter screen 200 and the air duct opening 110.

[0059] In other embodiments, the magnetic component 400 can also be disposed on the outer periphery of the air duct 110, which can also improve the fixing strength between the filter 200 and the air duct 110.

[0060] In some embodiments, the magnetic assembly 400 includes a magnetic element disposed at the edge of the filter 200 or on the outer periphery of the air duct 110, and the filter 200 can be attracted to or detached from the air duct 110 by the magnetic element.

[0061] In this embodiment, the magnetic element is disposed at the edge of the filter 200. Since the housing 100 is made of metal, the magnetic element can be attracted to the outer periphery of the air duct 110, thereby fixing the filter 200. There is no need to provide a component for attracting the magnetic element on the outer periphery of the air duct 110.

[0062] In other embodiments, the magnetic element can also be disposed on the outer periphery of the air duct 110. Since the filter screen 200 is made of metal, the magnetic element can be attracted to the filter screen 200, thereby achieving the same fixation of 200 without the need to provide a component on the filter screen 200 that is attracted to the magnetic element.

[0063] In some embodiments, the magnetic component 400 includes:

[0064] The first magnetic component 410 is connected to one side of the filter screen 200;

[0065] The cooking utensil filter installation structure also includes:

[0066] The first adsorption element 420 is provided on the housing 100 corresponding to the first magnetic element 410. The first magnetic element 410 is used to magnetically attract or detach from the first adsorption element 420. The filter screen 200 can be attracted or detached from the air duct opening 110 through the first magnetic element 410 and the first adsorption element 420.

[0067] In this application, by employing a first magnetic component 410 and a first adsorption component 420, the filter 200 is installed through non-contact magnetic coupling, eliminating the need for complex parts such as positioning pins or screws. This significantly simplifies the production assembly and daily maintenance process of the filter 200. Simultaneously, the uniform distribution of magnetic adsorption force ensures a tight fit between the first magnetic component 410 and the first adsorption component 420, thereby improving the fixing strength of the filter 200. Furthermore, the first magnetic component 410 and the first adsorption component 420 can be disassembled and installed by hand without tools, greatly reducing the difficulty and frequency of cleaning the filter 200 for users, thus extending the service life of the filter 200 and continuously ensuring the efficiency of kitchen air purification.

[0068] In this embodiment, one first magnetic element 410 and one first adsorption element 420 are provided. The first magnetic element 410 is provided on the surface of the filter screen 200 facing the housing 100 and is located at the top of the filter screen 200. The first adsorption element 420 is provided on the housing 100 and located at the top of the air duct opening 110. By providing the first magnetic element 410 and the first adsorption element 420 at the top of the filter screen 200 and the top of the air duct opening 110, the upper side of the filter screen 200 can be fixed by the first magnetic element 410 and the first adsorption element 420.

[0069] In other embodiments, the number of the first magnetic element 410 and the first adsorption element 420 can be adjusted as needed. For example, multiple first magnetic elements 410 and multiple first adsorption elements 420 can be set and the multiple first magnetic elements 410 can be evenly distributed along the edge of the top of the filter screen 200, or the multiple first magnetic elements 410 can be evenly distributed along the circumference of the filter screen 200.

[0070] In this embodiment, the first magnetic element 410 is elongated and is arranged along the length direction of one side edge of the filter screen 200, and the length of the elongated first magnetic element 410 is less than the length of one side edge of the filter screen 200.

[0071] In other embodiments, the shape of the first magnetic element 410 can be adaptively adjusted as needed, for example, the first magnetic element 410 can be set to a wave shape or an arc shape, thereby increasing the magnetic attraction area of ​​the first magnetic element 410 and further improving the fixing strength to the filter screen 200.

[0072] The magnetic assembly 400 also includes:

[0073] The second magnetic element 430 is provided on at least one of the opposite sides of the filter screen 200;

[0074] The cooking utensil filter installation structure also includes:

[0075] The second adsorption element 440 is provided on the housing 100 corresponding to the second magnetic element 430. The second magnetic element 430 is used to magnetically attract or detach from the second adsorption element 440. The filter screen 200 can be attracted to or detached from the air duct opening 110 through the second magnetic element 430 and the second adsorption element 440.

[0076] In this application, by employing the second magnetic component 430 and the second adsorption component 440, the filter 200 is installed through non-contact magnetic coupling, eliminating the need for complex parts such as positioning pins or screws. This significantly simplifies the production assembly and daily maintenance process of the filter 200. Simultaneously, the uniform distribution of magnetic adsorption force ensures a tight fit between the second magnetic component 430 and the second adsorption component 440, thereby improving the fixing strength of the filter 200. Furthermore, the second magnetic component 430 and the second adsorption component 440 can be manually installed and removed without tools, greatly reducing the difficulty and frequency of cleaning the filter 200 for users, thus extending the service life of the filter 200 and continuously ensuring the efficiency of kitchen air purification. The combination of the first magnetic component 410 and the second magnetic component 430 with the first adsorption component 420 and the second adsorption component 440 further enhances the fixing strength of the filter 200 to the housing 100.

[0077] In this embodiment, two second magnetic elements 430 and two second adsorption elements 440 are provided. The two second magnetic elements 430 are both provided on the surface of the filter screen 200 facing the housing 100. The two second magnetic elements 430 are respectively located on opposite sides of the filter screen 200 in the horizontal direction. The two second adsorption elements 440 are respectively provided on the housing 100 and located on opposite sides of the air duct opening 110. By providing the second magnetic elements 430 on opposite sides of the filter screen 200, both sides of the filter screen 200 can be fixed by the second magnetic elements 430 and the second adsorption elements 440, thereby further improving the fixing strength of the filter screen 200.

[0078] In other embodiments, the number of the second magnetic element 430 and the second adsorption element 440 can be adjusted as needed. For example, multiple second magnetic elements 430 and multiple adsorption elements 440 can be set and the multiple second magnetic elements 430 can be evenly distributed along the length direction of the two side edges of the filter screen 200, or the multiple second magnetic elements 430 can be evenly distributed along the circumference of the filter screen 200.

[0079] In this embodiment, the second magnetic element 430 is elongated and is arranged along the length direction of both sides of the filter screen 200, and the length of the elongated second magnetic element 430 is less than the length of both sides of the filter screen 200.

[0080] In other embodiments, the shape of the second magnetic element 430 can be adaptively adjusted as needed, for example, the second magnetic element 430 can be set to a wave shape or an arc shape, thereby increasing the magnetic attraction area of ​​the second magnetic element 430 and further improving the fixing strength to the filter screen 200.

[0081] The filter 200 includes a filtering section 210 and a connecting section 220. The connecting section 220 is arranged circumferentially along the filtering section 210. The first magnetic element 410 and the second magnetic element 430 are both arranged on the connecting section 220. The other side of the connecting section 220 relative to the first magnetic element 410 is set as a magnetic section 221. The area on the housing 100 corresponding to the magnetic section 221 is set as an adsorption area 120. The magnetic section 221 is used to magnetically attract or detach from the adsorption area 120. The filter 200 can attract or detach from the air duct opening 110 through the magnetic section 221 and the adsorption area 120.

[0082] In this application, by employing the magnetic part 221 and the adsorption area 120, the side of the filter screen 200 opposite to the first magnetic element 410 can be fixed to the housing 100 via the magnetic part 221 and the adsorption area 120. Through the combination of the magnetic part 221 and the adsorption area 120 with the first magnetic element 410 and the second magnetic element 430, the filter screen 200 can be fixed to the housing 100 on all four sides, thereby further improving the fixing strength between the filter screen 200 and the housing 100 and preventing the filter screen 200 from detaching from the housing 100 during use. The filter screen 200 is detached from the magnetic part 221 on one side of the connecting part 220 relative to the first magnetic part 410. It is not necessary to set an additional magnetic part on the filter screen 200. The filter screen 200 is fixed by utilizing the original magnetism of part of the filter screen 200 material, which reduces the cost. The area of ​​the housing 100 opposite to the magnetic part 221 is set as the adsorption area 120. It is not necessary to set an additional adsorption part on the housing 100 to be adsorbed by the magnetic part 221. The filter screen 200 is fixed by utilizing the original metal material of the housing 100, which further reduces the cost.

[0083] In this embodiment, filter holes are disposed on the filter section 210, and the connecting section 220 includes four connecting segments that are respectively opposite to the periphery of the filter section 210. The first magnetic element 410 is disposed on the surface of the connecting section 220 facing the housing 100, and the first magnetic element 410 is disposed on the upper connecting segment. Two second magnetic elements 430 are disposed on the surface of the connecting section 220 facing the housing 100, and the two second magnetic elements 430 are respectively disposed on two connecting segments of the connecting section 220 along the horizontal direction. The magnetic section 221 is the lower connecting segment. The four connecting segments can be integrally disposed, or the four connecting segments can be welded or glued together.

[0084] In this embodiment, the housing 100 is made of metal, and the adsorption area 120 is made of the same metal as the housing 100, so that there is no need to set up the adsorption area 120 separately, and the adsorption of the magnetic part 221 can be achieved by utilizing the original metal properties of the housing 100.

[0085] In other embodiments, the material of the adsorption region 120 of the housing 100 may be different from the material of the housing 100.

[0086] The magnetic force of the first magnetic element 410 is greater than that of the second magnetic element 430, and / or the magnetic force of the second magnetic element 430 is greater than that of the magnetic part 221.

[0087] In this embodiment, the magnetic force of the first magnetic element 410 is greater than that of the second magnetic element 430, and the magnetic force of the second magnetic element 430 is greater than that of the magnetic part 221.

[0088] In this application, by making the magnetic force of the first magnetic element 410 greater than that of the second magnetic element 430, and the magnetic force of the second magnetic element 430 greater than that of the magnetic part 221, the upper, middle, and lower parts of the filter screen 200 can be installed with the housing 100 in a manner with decreasing magnetic force. The upper part of the filter screen 200 can be firmly fixed to the housing 100 by the first magnetic element 410 and the first adsorption element 420, ensuring that the filter screen 200 as a whole does not fall off; the middle part of the filter screen 200 can be connected to the housing 100 by the second magnetic element 430 and the second adsorption element 440. The housing 100 is fixed, stabilizing the middle area of ​​the filter screen 200 and preventing the filter screen 200 from shaking. The lower part of the filter screen 200 can be aligned with the housing 100 and gently adsorbed through the magnetic part 221 and the adsorption area 120. This avoids the installation effort caused by strong adsorption and makes it easy for the user to correct when closing. This ensures that the filter screen 200 is stable and does not loosen, and makes the disassembly and assembly process smooth and effortless. Long-term use will not easily cause the housing 100 to deform or the edge of the filter screen 200 to warp due to excessive magnetic attraction. It takes into account the sturdiness, ease of operation and durability.

[0089] The first magnetic component 410 is a neodymium iron boron magnetic strip, and the first adsorption component 420 is an electroplated pure iron layer.

[0090] In this application, by using neodymium iron boron magnetic strips and an electroplated pure iron layer, the neodymium iron boron magnetic strips provide super strong magnetic force, ensuring that the filter screen 200 is tightly attached to the housing 100 and is not easy to loosen; the electroplated pure iron layer not only has high magnetic permeability and stable adsorption, but also has rust-proof and corrosion-resistant properties, and is not easy to rust and fall off even after long-term contact with oil fumes.

[0091] In this embodiment, the neodymium iron boron magnetic strip is an N52 neodymium iron boron magnetic strip. The maximum magnetic energy product of the N52 neodymium iron boron magnetic strip reaches 52 MGOe, which can provide extremely strong vertical adsorption force, ensuring that the filter screen 200 and the housing 100 fit tightly together and are not easy to loosen after long-term use.

[0092] In this embodiment, the neodymium iron boron magnetic strip can be integrally formed on the filter screen 200, or the neodymium iron boron magnetic strip can be fixed on the filter screen 200 by bolt connection, pasting, welding or snap-fit. The electroplated pure iron layer can be integrally formed on the housing 100, or the electroplated pure iron layer can be fixed on the housing 100 by bolt connection, pasting, welding or snap-fit.

[0093] In other embodiments, a groove for accommodating the first magnetic element 410 may be provided on the filter screen 200, and a groove for accommodating the first adsorption element 420 may be provided on the housing 100, so that when the first magnetic element 410 and the first adsorption element 420 are magnetically adsorbed, the filter screen 200 and the housing 100 can be seamlessly connected, thereby indirectly improving the sealing between the housing 100 and the filter screen 200.

[0094] The second magnetic component 430 is a ferrite magnetic strip, and the second adsorption component 440 is an iron-nickel plated alloy.

[0095] In this application, by adopting ferrite magnetic strips and a nickel-plated iron alloy layer, the ferrite magnetic strips are inexpensive and have good temperature resistance (can withstand temperatures above 200℃ for a long time), making them suitable for the high temperature and high humidity environment of range hoods; the nickel-plated iron alloy layer has high magnetic permeability and a rust-proof surface coating, which can stably adsorb the magnetic strips and resist oil fume corrosion for a long time; at the same time, the magnetic force is moderate and the adsorption is uniform, which can not only ensure the fixation of the filter screen 200 and the housing 100, but also avoid the installation effort or deformation of the housing 100 caused by excessive magnetic force.

[0096] In this embodiment, the ferrite magnetic strip can be integrally formed on the filter screen 200, or the ferrite magnetic strip can be fixed on the filter screen 200 by bolting, pasting, welding or snapping. The nickel-plated iron alloy can be integrally formed on the housing 100, or the nickel-plated iron alloy can be fixed on the housing 100 by bolting, pasting, welding or snapping.

[0097] In other embodiments, a groove for accommodating the first magnetic element 410 may be provided on the filter screen 200, and a groove for accommodating the first adsorption element 420 may be provided on the housing 100, so that when the first magnetic element 410 and the first adsorption element 420 are magnetically adsorbed, the filter screen 200 and the housing 100 can be seamlessly connected, thereby indirectly improving the sealing between the housing 100 and the filter screen 200.

[0098] The magnetic part 221 is a magnetically conductive stainless steel sheet, and the adsorption area 120 is a steel plate.

[0099] In this application, by using a magnetically conductive stainless steel sheet and a steel plate, the magnetically conductive stainless steel sheet has both magnetic conductivity and corrosion resistance, which can stably adsorb the steel plate and resist the erosion of kitchen fumes for a long time; the steel plate itself has high strength and low cost, and can provide a reliable adsorption surface without additional coating; at the same time, the magnetic force is moderate and the adsorption is uniform, which can ensure that the filter screen 200 and the air duct 110 are tightly closed, and avoid the installation effort or deformation of the housing 100 caused by excessive magnetic force.

[0100] In this embodiment, since the four connecting segments of the connecting part 220 are integrally formed and all four connecting segments are stainless steel sheets, the bottom connecting segment of the four connecting segments is the magnetic part 221. All four connecting segments can be set as magnetically conductive stainless steel sheets, or the bottom connecting segment can be set as a magnetically conductive stainless steel sheet alone. Since the adsorption area 120 is part of the housing 100, by setting the entire housing 100 as steel, the housing 100 and the adsorption area 120 do not need to be set as different materials.

[0101] The alignment component 300 includes a snap-fit ​​part 310 and a snap fastener 320. The snap-fit ​​part 310 is disposed on the air duct opening 110, and the snap fastener 320 is disposed on the filter screen 200. The snap fastener 320 engages or disengages from the snap-fit ​​part 310 to fix or disengage the filter screen 200 from the air duct opening 110.

[0102] In this application, by adopting the setting of snap-fit ​​part 310 and snap fastener 320, during installation, simply align the snap fastener 320 with the snap-fit ​​part 310 and press lightly to automatically engage, without the need for tools or additional operations, which is simple and quick; the snap fastener 320 and the snap-fit ​​part 310 form a self-locking structure, which is not easy to loosen or shift after long-term use, ensuring that the filter screen 200 and the air duct 110 always maintain precise alignment.

[0103] In this embodiment, the latching part 310 is configured as a latching groove, which is located on the bottom wall of the air duct opening 110. There are two latching grooves, which are respectively located on both sides of the bottom wall of the air duct opening 110. The buckle 320 is L-shaped. The L-shaped buckle 320 includes a first latching section 321 and a second latching section 322. One end of the first latching section 321 is connected to the magnetic part 221, and the first latching section 321 is perpendicular to the magnetic part 221. One end of the second latching section 322 is connected to the first latching section 321, and the second latching section 322 is perpendicular to the first latching section 321. The latching groove is used for the first latching section 321 and the second latching section 322 to pass through. At this time, the first latching section 321 abuts against the bottom wall of the latching groove, and the second latching section 322 abuts against the inner side of the edge of the air duct opening 110, so that the buckle 320 and the latching part 310 are latched.

[0104] In other embodiments, the structure of the snap-fit ​​part 310 and the buckle 320 can be adapted as needed. For example, the snap-fit ​​part 310 can be set as a snap-fit ​​hole, and the buckle 320 can include a connecting rod and a rubber ring sleeved and fixedly connected to the connecting rod. By driving the connecting rod through the snap-fit ​​hole, the rubber ring resists its own elasticity and passes through the snap-fit ​​hole. At this time, the rubber ring can abut against the back of the edge of the air duct 110, which can also realize the installation and fixation between the filter screen 200 and the housing 100.

[0105] Combination Figure 1 , Figure 5 and Figure 6 In this embodiment, the cooking appliance filter installation structure further includes a first detection component, which includes a differential pressure sensor. The differential pressure sensor is disposed on the housing 100 and has two measurement interfaces 500. The two measurement interfaces 500 are respectively disposed inside the housing 100 and located on the air inlet side and air outlet side of the filter 200. The two measurement interfaces 500 are used to detect the air inlet pressure on the air inlet side and the air outlet pressure on the air outlet side of the filter 200, respectively. When the difference between the air inlet pressure and the air outlet pressure is greater than or equal to the preset pressure, it indicates that the filter 200 has serious residual oil stains. At this time, the controller controls the indicator light disposed on the housing 100 to flash, prompting the user that the filter 200 needs to be cleaned. When the difference between the air inlet pressure and the air outlet pressure is less than the preset pressure, the controller controls the indicator light disposed on the housing 100 to stay on, indicating that the filter 200 has little residual oil stains and the filter 200 does not need to be cleaned.

[0106] Combination Figure 1 , Figure 5 and Figure 6In this embodiment, the cooking appliance filter installation structure further includes a second detection component, which includes a Hall sensor 600. The Hall sensor 600 is disposed inside the housing 100. The Hall sensor 600 is used to detect the number of times the filter 200 is removed. When the number of removals reaches 50, the controller controls a buzzer on the housing 100 to sound, prompting the user to perform a deep cleaning of the filter 200 and replace the seal between the filter 200 and the housing 100.

[0107] In this embodiment, the cooking appliance is a range hood. In other embodiments, the cooking appliance can also be replaced by a dishwasher, water purifier, air fryer, oven, or induction cooker, or other cooking appliances that require the use of filter 200.

[0108] The cooking appliance filter installation structure provided in this application allows for the following steps when installing the filter 200: First, the filter 200 is moved towards the air duct 110. The buckle 320 on the connecting part 220 moves towards the engaging part 310, allowing the buckle 320 to engage with the engaging part 310. At this point, the magnetic part 221 at the bottom of the filter 200 magnetically attracts the adsorption area 120. By continuously moving the filter 200 closer to the air duct 110, the second magnetic elements 430 on both sides of the middle of the filter 200 magnetically attract the second adsorption elements 440 on both sides of the air duct 110 of the housing 100. The first magnetic element 410 at the top of the filter 200 magnetically attracts the first adsorption element 420 on the upper side of the air duct 110 of the housing 100, thus fixing the filter 200. The engaging part 310 and the buckle 320 can engage the first magnetic element 410, the first adsorption element 420, and the second magnetic element 440. The positioning of the first magnetic component 430, the second adsorption component 440, the magnetic part 221, and the adsorption area 120 ensures that the first magnetic component 410 and the first adsorption component 420, the second magnetic component 430 and the second adsorption component 440, the magnetic part 221, and the adsorption area 120 are aligned. This prevents the filter screen 200 from shifting position relative to the air duct 110 during installation, and prevents unfiltered air from entering the housing 100 along the gap between the filter screen 200 and the air duct 110. This prevents oil fumes from affecting other components inside the cooking equipment, and eliminates the need for users to repeatedly adjust the position of the filter screen 200, thus facilitating its installation. The use of snap-fit ​​and magnetic attraction makes the fixing method convenient and simple, improving the efficiency of user installation and removal of the filter screen 200 and increasing the fixing strength of the filter screen 200 to the air duct 110, preventing the filter screen 200 from detaching from the air duct 110 during use.
