Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more specifically, to an oil fume treatment device. Background Technology

[0002] Range hoods are an indispensable piece of equipment in modern kitchens. They can effectively filter the fumes produced during cooking, protect users' health, and keep the kitchen clean.

[0003] However, existing range hoods present significant cleaning challenges during use. The need to disassemble or clean hard-to-reach parts not only increases the workload but also reduces cleaning efficiency. This is especially true for home users, as the complex disassembly and cleaning process requires time and skill, often leading them to neglect or postpone regular cleaning, thus impacting the kitchen's hygiene.

[0004] Therefore, how to reduce the difficulty of cleaning range hoods, improve cleaning efficiency, and improve the kitchen hygiene environment is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this application is to provide a new technical solution for an oil fume treatment device.

[0006] According to one aspect of this application, an oil fume treatment device is provided, comprising a housing, a guide plate, and an oil fume separation mesh. The housing has an air inlet area, and an air inlet and an air outlet are provided on the housing, the air inlet and the air outlet respectively communicating with the air inlet area. The guide plate is disposed at a corner of the air inlet area, and one side of the guide plate is connected to the air inlet, and the other side is connected to the air outlet. The guide plate encloses an air inlet duct within the air inlet area, the cross-sectional area of ​​which gradually decreases from the air inlet to the air outlet. The oil fume separation mesh is inserted between the housing and the guide plate, and covers the air inlet.

[0007] Optionally, the outer casing has a first baffle, a second baffle, and a first connecting plate. The first baffle and the second baffle are disposed on opposite sides of the air inlet from top to bottom. The first connecting plate is located on the side of the second baffle closer to the air inlet area and is provided with a bearing surface for supporting the oil fume separation mesh. When the oil fume separation mesh is located at the air inlet, the bottom of the oil fume separation mesh is located on the bearing surface, and the top and bottom of the side of the oil fume separation mesh closer to the air inlet abut against the first baffle and the second baffle, respectively.

[0008] Optionally, a first insertion area is formed between the first baffle and the top of the guide plate near the air inlet, and a second insertion area is formed between the second baffle and the bottom of the guide plate near the air inlet. When the oil fume separation mesh is installed at the air inlet, the opposite ends of the oil fume separation mesh are respectively inserted into the first insertion area and the second insertion area.

[0009] Optionally, the guide plate has a relief groove on the side near the air inlet. The relief groove is formed by a recess in the direction from the air inlet to the air outlet. When the oil fume separation net moves from the second baffle to the first baffle, the relief groove is used to avoid the top of the oil fume separation net.

[0010] Optionally, the air inlet is provided with a support member, which divides the air inlet into a first air inlet and a second air inlet. Both the first air inlet and the second air inlet are provided with the oil fume separation mesh, and the adjacent ends of the two oil fume separation meshes are respectively mounted on the support member.

[0011] Optionally, the housing further includes a second connecting plate disposed between the guide plate and the first baffle, and the two opposite ends of the support member are respectively connected to the first connecting plate and the second connecting plate.

[0012] Optionally, the first baffle protrudes from the second connecting plate in the direction from the first baffle to the second baffle. When the oil fume separation mesh is located at the air inlet, there is a gap between the oil fume separation mesh and the second connecting plate. The gap is used for the oil fume separation mesh to move along the second baffle in the direction from the first baffle. The direction from the first baffle to the second baffle is the first direction, and the size of the gap along the first direction is equal to or greater than the size of the oil fume separation mesh abutting against the second baffle along the first direction.

[0013] Optionally, an oil guide groove is provided on the side of the support member near the air inlet duct, and the oil guide groove is formed by extending from the first baffle to the second baffle.

[0014] Optionally, the fume treatment device further includes an oil storage tank, which is detachably installed on the outer shell and located below the fume separation net, and the oil storage tank is connected to the oil guide channel.

[0015] Optionally, a cavity is formed between the guide plate and the outer casing.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] Oily air enters the air intake duct of the casing through the oil fume separation mesh covering the air inlet. As the oily air passes through the oil fume separation mesh, the mesh effectively separates the oil fumes from the airflow, causing the grease to settle on the mesh. Inside the casing, the baffle plate forms an air intake duct that gradually narrows from the air inlet to the air outlet. The airflow separated by the oil fume separation mesh flows smoothly through the air intake duct and is discharged through the air outlet.

[0018] As described above, since the baffle is positioned at the corner of the air intake area, it effectively prevents cooking fumes from entering the corner, reducing condensation in dead spaces like corners and thus simplifying cleaning. Simultaneously, the baffle creates a narrower air intake duct within the air intake area, guiding the airflow and reducing turbulence at corners. This not only effectively reduces noise from airflow impact but also shortens the airflow path from the intake to the outlet, effectively reducing... The system reduces the residence time of oily fumes in the air inlet duct, thereby decreasing the degree of condensation on the inner wall of the duct and improving its cleanliness. Furthermore, by inserting an oil fume separation mesh to cover the air inlet, it not only effectively separates oil fumes from the airflow before they enter the duct, reducing the amount of grease entering and improving the cleanliness of the duct, but also effectively reduces the difficulty of disassembling and assembling the oil fume separation mesh through its plug-in installation and removal method. This facilitates cleaning of the oil fume separation mesh, effectively reducing cleaning difficulty and improving the cleaning efficiency of the oil fume treatment device.

[0034] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0035] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0037] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] According to one embodiment of this application, an oil fume treatment device is provided. The oil fume treatment device includes a housing 1, a guide plate 2, and an oil fume separation mesh 3. The housing 1 has an air inlet area 11, and an air inlet 12 and an air outlet 13 are provided on the housing 1, respectively communicating with the air inlet area 11. The guide plate 2 is disposed at a corner of the air inlet area 11, with one side connected to the air inlet 12 and the other side connected to the air outlet 13. The guide plate 2 encloses an air inlet duct 21 within the air inlet area 11, with the cross-sectional area gradually decreasing from the air inlet 12 to the air outlet 13. The oil fume separation mesh 3 is inserted between the housing 1 and the guide plate 2, and covers the air inlet 12.

[0040] like Figures 1 to 7 As shown, the outer casing 1 includes a back panel, a top panel, and a side panel. The back panel, top panel, and side panel enclose an air intake area 11 with an air inlet 12 on one side. An air outlet 13 is opened on the top panel to facilitate the discharge of oil fumes from the air intake area 11.

[0041] The air inlet area 11 of the outer casing 1 has a corner, and the guide plate 2 forms an air inlet duct 21 at the corner of the air inlet area 11, which gradually narrows from the air inlet 12 to the air outlet 13. The oil fumes entering through the air inlet 12 are discharged through the air outlet 13 through the air inlet duct 21. By setting the air inlet duct 21 into a smooth structure with a gradual narrowing, it not only helps to reduce the collision of oil fumes and airflow in the air inlet duct 21, making the airflow from the air inlet 12 to the air outlet 13 smoother, thereby reducing the noise of the oil fume treatment device during use, but also facilitates the guidance of oil fumes and airflow, thereby reducing the flow path of oil fumes and airflow in the air inlet duct 21, shortening the residence time of oil fumes and airflow in the air inlet duct 21, reducing the degree of condensation of oil fumes on the inner wall of the guide plate 2, and effectively improving the cleanliness of the air inlet duct 21.

[0042] In this embodiment, the air inlet 21 formed by the guide plate 2 can be conical, arc-shaped, or other shapes, and is not limited to the above structure. Those skilled in the art can make the settings according to actual needs.

[0043] The oil fume separation net 3 is plate-shaped and is inserted into and covers the air inlet 12. By detachably connecting the oil fume separation net 3 to the outer shell 1, the difficulty of installing and removing the oil fume separation net 3 is effectively reduced, so as to facilitate the removal of the oil fume separation net 3 for cleaning and improve cleaning efficiency.

[0044] In this embodiment, the oil-fume-containing air enters the air inlet duct 21 of the outer casing 1 through the oil fume separation net 3 covering the air inlet 12. When the oil-fume-containing air passes through the oil fume separation net 3, the oil fume separation net 3 can effectively separate the oil fume from the airflow, so that the grease settles on the oil fume separation net 3. The guide plate 2 forms an air inlet duct 21 that becomes narrower and narrower from the air inlet 12 to the air outlet 13 inside the outer casing 1. The airflow separated by the oil fume separation net 3 passes smoothly through the air inlet duct 21 and is discharged through the air outlet 13.

[0045] As can be seen from the above, since the guide plate 2 is located at the corner of the air inlet area 11, it can block oil fumes from entering the corner, reducing the condensation of oil fumes in dead corners and other areas, thus reducing the difficulty of cleaning. Simultaneously, the guide plate 2 encloses the air inlet duct 21 within the air inlet area 11, forming an air inlet channel 21 with a gradually narrowing cross-section from the air inlet 12 to the air outlet 13. This guides the airflow, reducing turbulence at the corner, effectively reducing noise from airflow impact, and shortening the airflow path from the air inlet 12 to the air outlet 13, effectively reducing... The shorter residence time of the oil fume airflow in the air inlet duct 21 reduces the degree of condensation of oil fumes on the inner wall of the air inlet duct 21, improving the cleanliness of the air inlet duct 21. Moreover, by inserting the oil fume separation net 3 to cover the air inlet 12, it can not only effectively separate the oil fume and airflow before the oil fume enters the air inlet duct 21, thereby reducing the amount of grease entering the air inlet duct 21 and improving the cleanliness of the air inlet duct 21, but also effectively reduce the difficulty of disassembling and assembling the oil fume separation net 3 through the insertion and disassembly method, so as to facilitate the cleaning treatment of the oil fume separation net 3, effectively reducing the cleaning difficulty and improving the cleaning efficiency of the oil fume treatment device.

[0046] In one example, the outer casing 1 has a first baffle 14, a second baffle 15, and a first connecting plate 16. The first baffle 14 and the second baffle 15 are arranged from top to bottom on two opposite sides of the air inlet 12. The first connecting plate 16 is located on the side of the second baffle 15 near the air inlet area 11 and is provided with a bearing surface for supporting the oil fume separation net 3. When the oil fume separation net 3 is located at the air inlet 12, the bottom of the oil fume separation net 3 is located on the bearing surface. The top and bottom of the side of the oil fume separation net 3 near the air inlet 12 abut against the first baffle 14 and the second baffle 15, respectively.

[0047] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the air inlet 12 is quadrilateral, with a first baffle 14 positioned at the top and a second baffle 15 positioned at the bottom. A first connecting plate 16 is positioned at the bottom of the air inlet 12 to support the oil fume separation mesh 3. One side of the first connecting plate 16 is connected to the back plate via a folded edge, and the other side abuts against the second baffle 15.

[0048] When the oil fume separation mesh 3 covers the air inlet 12, the top of the oil fume separation mesh 3 abuts against the first baffle 14, and the bottom of the oil fume separation mesh 3 abuts against the bearing surface of the first connecting plate 16. The second baffle 15 and the first connecting plate 16 limit the position of the bottom of the oil fume separation mesh 3 on the bearing surface, so as to prevent the bottom of the oil fume separation mesh 3 from detaching from the bearing surface when using the oil fume treatment device, thus affecting the performance of the oil fume separation mesh 3.

[0049] By detachably connecting the oil fume separation net 3 to the outer shell 1, the difficulty of installing and removing the oil fume separation net 3 is effectively reduced, making it easier to disassemble the oil fume separation net 3 for cleaning and improving cleaning efficiency.

[0050] In the first embodiment of this application:

[0051] A first insertion area 141 is formed between the first baffle 14 and the top of the guide plate 2 near the air inlet 12, and a second insertion area 151 is formed between the second baffle 15 and the bottom of the guide plate 2 near the air inlet 12. When the oil fume separation net 3 is installed at the air inlet 12, the opposite ends of the oil fume separation net 3 are respectively inserted into the first insertion area 141 and the second insertion area 151.

[0052] like Figures 4 to 7 As shown, a first baffle 14 is disposed at the top of the air inlet 12, and a first insertion area 141 is formed between the first baffle 14 and the guide plate 2. A second baffle 15 is disposed at the bottom of the air inlet 12, and a second insertion area 151 is formed between the second baffle 15 and the guide plate 2. The first insertion area 141 and the second insertion area 151 are correspondingly disposed.

[0053] When the oil fume separation net 3 covers the air inlet 12, the top of the oil fume separation net 3 is inserted into the first insertion area 141, and the bottom of the oil fume separation net 3 is inserted into the second insertion area 151. By inserting the oil fume separation net 3 into the first insertion area 141 and the second insertion area 151 to cover the air inlet 12, the oil fume separation net 3 can be quickly installed and removed for cleaning, thereby effectively improving cleaning efficiency.

[0054] An interface adapted to the oil fume separation mesh 3 is opened on the side wall of the outer casing 1, and the oil fume separation mesh 3 is covered at the air inlet 12 by side insertion.

[0055] When it is necessary to disassemble the oil fume separation net 3, move the oil fume separation net 3 laterally through the plug interface to pull it out of the installation port. The removed oil fume separation net 3 can then be cleaned. After cleaning, the oil fume separation net 3 needs to be installed. Insert the side end of the oil fume separation net 3 into the plug interface, with the top of the oil fume separation net 3 extending into the first plug area 141 and the bottom extending into the second plug area 151, until the oil fume separation net 3 covers the installation port. The installation is then complete.

[0056] This side-mounted plug-in installation and removal method is simple to operate, effectively reducing the difficulty of disassembly and assembly and improving cleaning efficiency.

[0057] In the second embodiment of this application:

[0058] When the oil fume separation mesh 3 covers the air inlet 12, there is a rotation space between the first baffle 14 and the guide plate 2, and the top of the oil fume separation mesh 3 is located within the rotation space. By setting the rotation space, the oil fume separation mesh 3 can rotate around its top during installation and disassembly, allowing the bottom of the oil fume separation mesh 3 to rotate into or out of the second baffle 15. The clearance groove 22 is located above the top of the oil fume separation mesh 3, allowing the top of the oil fume separation mesh 3 to be cleared, so that the oil fume separation mesh 3 can rotate within the rotation space. This prevents the edge of the guide plate 2 from abutting against the top of the oil fume separation mesh 3 during loading and unloading, reducing the difficulty of loading and unloading operations and improving loading and unloading efficiency.

[0059] When disassembling the oil fume separator 3 for cleaning, move the oil fume separator 3 from the second baffle 15 towards the first baffle 14 (moving it upwards) so that the top of the oil fume separator 3 is in the rotation space until the bottom of the oil fume separator 3 is exposed above the second baffle 15. Rotate the oil fume separator 3 around the top edge of the oil fume separator 3 so that the bottom of the oil fume separator 3 moves to the side of the second baffle 15 away from the air inlet 12. Then move the oil fume separator 3 from the first baffle 14 towards the second baffle 15 (moving it downwards) until the top of the oil fume separator 3 is detached from the first baffle 14, and the disassembly is complete.

[0060] After the oil fume separation net 3 is cleaned, insert the top of the oil fume separation net 3 between the first baffle 14 and the guide plate 2, and move the oil fume separation net 3 from the second baffle 15 toward the first baffle 14 (moving upwards) so that the top of the oil fume separation net 3 abuts against the first baffle 14 and is located in the rotation space, until the bottom of the oil fume separation net 3 is higher than the top of the second baffle 15. Rotate the oil fume separation net 3 around the top edge of the oil fume separation net 3 so that the bottom end of the oil fume separation net 3 moves to the side of the second baffle 15 near the air inlet 12. Then move the oil fume separation net 3 from the first baffle 14 toward the second baffle 15 (moving downwards) until the bottom of the oil fume separation net 3 rests on the bearing surface of the first connecting plate 16, and the installation is completed.

[0061] like Figures 4 to 7 As shown, the baffle plate 2 is connected to the outer shell 1 by a folded edge. The folded edge is located between the baffle plate 2 and the outer shell 1. This not only effectively reduces the connection structure between the outer shell 1 and the air inlet duct 21, but also effectively reduces the scratches caused by protruding connectors during the cleaning process, improving the safety of the cleaning process. It also reduces the cleaning difficulty caused by the condensation of oil stains, effectively improving the cleaning efficiency.

[0062] In one example, the air inlet 12 is provided with a support member 4, which divides the air inlet 12 into a first air inlet and a second air inlet. Both the first air inlet and the second air inlet are provided with the oil fume separation mesh 3, and the adjacent ends of the two oil fume separation meshes 3 are respectively attached to the support member 4.

[0063] like Figures 1 to 7 As shown, the support member 4 is prismatic in shape and is located at the air inlet 12, dividing the air inlet 12 into a first air inlet and a second air inlet arranged on the left and right. By dividing the air inlet 12 into multiple parts, relatively small oil fume separation nets 3 can be installed. By installing multiple small oil fume separation nets 3, the oil fume separation effect is not reduced, but the weight of a single oil fume separation net 3 is also effectively reduced, further reducing the difficulty of disassembling the oil fume separation net 3 and improving cleaning efficiency.

[0064] By setting support members 4 between adjacent oil fume separation nets 3, the oil fume separation nets 3 are supported by the support members 4, thereby improving the installation stability of the oil fume separation nets 3 and preventing multiple small oil fume separation nets 3 from falling off the air inlet 12, which would affect the safety of the oil fume treatment device.

[0065] Of course, the support member 4 in this embodiment is not limited to the above-described structure and quantity, and those skilled in the art can set it according to actual needs. For example, the support member 4 can also be plate-shaped, or there can be two or three support members 4.

[0066] In one example, the outer casing 1 further includes a second connecting plate 17 disposed between the guide plate 2 and the first baffle 14, and the two opposite ends of the support member 4 are respectively connected to the first connecting plate 16 and the second connecting plate 17.

[0067] like Figures 5 to 7 As shown, the second connecting plate 17 is rectangular and is connected to the outer casing 1 via a folded edge, and fixed within the air inlet area 11. The top of the support member 4 is connected to the second connecting plate 17, and the bottom of the support member 4 is connected to the first connecting plate 16. The first connecting plate 16 and the second connecting plate 17 are used to enhance the stability of the support member 4 within the outer casing 1, thereby improving the installation stability of the oil fume separation mesh 3.

[0068] In one example, the first baffle 14 protrudes from the second connecting plate 17 in the direction of the second baffle 15. When the oil fume separation mesh 3 is located at the air inlet 12, there is a gap 18 between the oil fume separation mesh 3 and the second connecting plate 17. The gap 18 is used for the oil fume separation mesh 3 to move along the second baffle 15 towards the first baffle 14. The direction along the first baffle 14 towards the second baffle 15 is the first direction, and the size of the gap 18 along the first direction is equal to or greater than the size of the oil fume separation mesh 3 abutting against the second baffle 15 along the first direction.

[0069] When the fume separation mesh 3 covers the air inlet 12, the second connecting plate 17 is located above the fume separation mesh 3, forming a gap 18 between the second connecting plate 17 and the fume separation mesh 3. The size of this gap 18 along the first direction is equal to or greater than the size of the second insertion area 151 along the first direction. That is, when the fume separation mesh 3 moves along the second baffle 15 towards the first baffle 14, the gap 18 can accommodate the fume separation mesh 3 moving upward until the bottom of the fume separation mesh 3 disengages from the second insertion area 151, so that the fume separation mesh 3 can be removed.

[0070] The first direction is the movement from the first baffle 14 to the second baffle 15 or the movement from the second baffle 15 to the first baffle 14.

[0071] The second connecting plate 17 has a wire guide plate with through holes for connecting wires of electrical components such as switches and lighting fixtures. A mounting cavity is formed between the wire guide plate and the first baffle 14. This mounting cavity is used for laying wires. The mounting cavity formed by the first baffle 14 and the wire guide plate effectively reduces the condensation of oil fumes on the wires, improving the cleanliness of the wires and reducing the corrosion of the wires by oil fumes, thus extending the service life of the equipment.

[0072] In one example, an oil guide groove 41 is provided on one side of the support member 4 near the air inlet duct 21, and the oil guide groove 41 is formed by extending from the first baffle 14 to the second baffle 15.

[0073] like Figures 6 to 7 As shown, the support member 4 is provided with an oil guide groove 41. The oil guide groove 41 is used to guide the oil stains adhering to the inner wall of the air inlet duct 21. Through the oil guide groove 41, some of the oil stains on the inner wall of the air inlet duct 21 are guided to the oil storage tank 51, preventing the oil stains from blocking or accumulating in the air inlet duct 21, and effectively reducing the difficulty of cleaning the air inlet duct 21.

[0074] In one example, the fume treatment device further includes an oil storage tank 5, which is detachably installed on the outer casing 1 and located below the fume separation net 3. The oil storage tank 51 is connected to the oil guide channel 41.

[0075] like Figures 4 to 7 As shown, the oil storage tank 5 is located at the bottom of the outer casing 1. The oil storage tank 5 collects and stores the oil stains in the air inlet duct 21, so that the oil stains can be centrally treated during cleaning and the cleaning efficiency can be improved.

[0076] An oil guide hole is provided on the first connecting plate 16. The oil guide hole corresponds to the oil guide groove 41 and is connected to the oil storage tank 51. The oil sludge in the oil guide groove 41 is leaked into the oil storage tank 51 through the oil guide hole, so as to prevent the oil sludge flowing down the oil guide groove 41 from accumulating on the first connecting plate 16. This will not only affect the installation and removal of the oil fume separation net 3, but also increase the difficulty of cleaning the air inlet duct 21.

[0077] In one example, a cavity 19 is formed between the deflector 2 and the outer shell 1.

[0078] like Figure 4 and Figure 5 As shown, a hollow structure is formed between the air inlet duct 21 and the outer casing 1 to improve the noise reduction effect of the fume treatment device.

[0079] The cavity 19 can also be filled with noise-reducing material to further reduce the noise reduction effect.

[0080] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
