Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oil mesh structure and an island range hood. Background Technology
[0002] In the field of modern kitchen appliances, island-style range hoods, as core components of integrated cooking environments, directly impact user experience through their aerodynamic performance and purification efficiency. To achieve grease separation, current technologies generally employ a fixed oil mesh structure, which intercepts particulate matter in the oil fume airflow through inertial impaction. However, due to fluid dynamics, when high-temperature oil fumes containing saturated water vapor (temperature range approximately 60-120℃) come into contact with the cooler surface of the oil mesh, a condensation effect occurs, leading to dynamic deposition of grease and condensate on the mesh surface. This deposition phenomenon exhibits uneven spatial distribution, specifically: a continuous oil film layer forms on the windward side of the mesh, while capillary coagulation occurs at the mesh edges, ultimately resulting in a reduction in the effective flow area.
[0003] Clogging of the mesh causes secondary escape of cooking fumes and shortens the cleaning and maintenance cycle to 2-3 times that under normal use conditions. Although there are improvement solutions in the existing technology such as inclined guide plates and honeycomb composite filters, the contradiction between dynamic oil droplet adhesion and ease of cleaning has not been fundamentally resolved, becoming a key technical bottleneck restricting the long-term performance stability of range hoods.
[0004] Therefore, an oil mesh structure is urgently needed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an oil mesh structure and an island-style range hood to solve the problem that existing oil mesh structures are prone to grease buildup, which leads to a decrease in the effective gas flow area of the oil mesh structure and is not conducive to long-term stable operation.
[0006] On the one hand, this utility model provides an oil mesh structure, which is installed in the flue gas inlet. The oil mesh structure includes:
[0007] The rotating assembly includes a first rotating oil screen, which includes a first oil screen and a plurality of first blades arranged sequentially and spaced apart around the outer peripheral wall of the first oil screen, with a filter channel formed between any two adjacent first blades.
[0008] The driving component drives the first rotating oil screen to rotate.
[0009] As a preferred technical solution for the oil mesh structure, the rotating component also includes a second rotating oil mesh, which is coaxially arranged with the first rotating oil mesh, and the driving component drives the second rotating oil mesh to rotate.
[0010] As a preferred technical solution for oil network structures, the following also include:
[0011] The retaining ring has its peripheral wall divided into a first part and a second part along its axis. The first part is provided with an oil slinger hole, and the second part is provided with a filter hole. The rotating component is located in the first part.
[0012] The second part of the oil storage tank is positioned opposite the opening of the oil storage tank.
[0013] As a preferred technical solution for the oil mesh structure, the driving component is located inside the oil storage tank and is fixedly connected to the oil storage tank.
[0014] As a preferred technical solution for the oil mesh structure, the driving component includes a motor and an oil-proof sleeve. The oil-proof sleeve is fixedly connected to the oil storage tank, and the motor is inserted into the oil-proof sleeve and fixed relative to the oil-proof sleeve.
[0015] As a preferred technical solution for the oil network structure, the oil storage shell is provided with an open oil storage cavity, and the second part passes through the open and extends into the oil storage cavity.
[0016] As a preferred technical solution for the oil network structure, an annular inner flange is provided at the opening of the oil storage shell. The annular inner flange abuts against the second part, and multiple oil guide holes communicating with the oil storage chamber are arranged sequentially at intervals along the circumference of the annular inner flange.
[0017] As a preferred technical solution for the oil mesh structure, an oil-water filter membrane is also included, which is attached to the outer peripheral wall of the fixing ring and blocks the oil throwing hole and the filter hole.
[0018] As a preferred technical solution for the oil mesh structure, it also includes a fixed oil mesh, which is disposed within the first part and located on the side of the first rotating oil mesh away from the second part.
[0019] On the other hand, this utility model provides an island-style smoke hood, including the oil mesh structure in any of the above-mentioned solutions.
[0020] The beneficial effects of this utility model are:
[0021] The oil mesh structure includes a rotating component and a driving component. The rotating component includes a first rotating oil mesh, which comprises a first oil mesh and multiple first blades arranged at intervals around its outer peripheral wall, with a filtration channel formed between any two adjacent first blades. The driving component drives the first rotating oil mesh to rotate. This oil mesh structure is installed inside the smoke inlet of an island-style range hood. When the range hood is working, the fumes pass through the oil mesh structure. During this process, the oil in the fumes is filtered by the first oil mesh and adheres to it. The driving component drives the first oil mesh to rotate, and under the action of centrifugal force, the grease on the first oil mesh is thrown off, effectively improving the grease blockage of the mesh openings and preventing the effective flow area of the first rotating oil mesh from decreasing too quickly, thus increasing the cleaning and maintenance cycle of the first rotating oil mesh. Simultaneously, the first oil mesh drives the multiple first blades to rotate synchronously around its axis. The negative pressure generated by the rotation of the first blades increases the suction force of the smoke inlet, improving the smoke extraction effect. Attached Figure Description

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0037] like Figures 1 to 5As shown, this embodiment provides an oil mesh structure, which includes a rotating component 1 and a driving component 2. The rotating component 1 includes a first rotating oil mesh 11, which includes a first oil mesh 111 and a plurality of first blades 112 arranged sequentially and spaced around the outer peripheral wall of the first oil mesh 111. A filter channel 1121 is formed between any two adjacent first blades 112. The driving component 2 drives the first rotating oil mesh 11 to rotate. This oil mesh structure is installed in the smoke inlet of an island-style range hood. When the island-style range hood is working, the fumes pass through the oil mesh structure. During this process, the oil in the fumes is filtered by the first oil mesh 111 and then adheres to the first oil mesh 111. The driving component 2 drives the first oil mesh 111 to rotate, and under the action of centrifugal force, the grease on the first oil mesh 111 is shaken off, thereby effectively improving the grease blockage of the mesh openings on the first oil mesh 111, avoiding the rapid decay of the effective flow area of the first rotating oil mesh 111, and increasing the cleaning and maintenance cycle of the first rotating oil mesh 11. At the same time, the first oil mesh 111 drives multiple first blades 112 to rotate synchronously around the axis of the first oil mesh 111. The negative pressure generated by the rotation of the first blades 112 can increase the suction of the flue and improve the smoke extraction effect.
[0038] Optionally, the mesh openings on the first oil mesh 111 are arranged in a circular array around the axis of the first oil mesh 111.
[0039] Optionally, the first rotating oil screen 11 further includes a reinforcing ring. Both the first oil screen 111 and the first blade 112 are disposed within the reinforcing ring. One end of the first blade 112 is fixedly connected to the first oil screen 111, and the other end of the first blade 112 is fixedly connected to the reinforcing ring. This arrangement can improve the strength and hardness of the first blade 112 through the reinforcing ring, preventing the first blade 112 from detaching from or deforming from the first oil screen 111.
[0040] Optionally, the first rotating oil screen 11 is a one-piece molded part. Specifically, it is manufactured by 3D printing or casting.
[0041] Optionally, the rotating assembly 1 further includes a second rotating oil screen 12, which is coaxially arranged with the first rotating oil screen 11. The driving member 2 drives the first oil screen 111 to rotate, and the first oil screen 111 drives the second rotating oil screen 12 to rotate. In this embodiment, the second rotating oil screen 12 is located on the side of the first oil screen 111 away from the driving member 2, and the first oil screen 111 and the second rotating oil screen 12 are stacked on top of each other, further improving the filtration effect of the oil screen structure.
[0042] In other embodiments, the driving member 2 can also drive the second rotating oil mesh 12 to rotate, and the second rotating oil mesh 12 can drive the first oil mesh 111 to rotate.
[0043] In other embodiments, the drive shaft of the drive component 2 can be connected to the first oil mesh 111 and the second rotating oil mesh 12 respectively, thereby synchronously driving the first oil mesh 111 and the second rotating oil mesh 12 to rotate. In this embodiment, this arrangement allows the first oil mesh 111 and the second rotating oil mesh 12 to be set independently, thus allowing them to be separated from each other, which is beneficial for subsequent cleaning and maintenance.
[0044] In other embodiments, the second rotating oil screen 12 includes a second oil screen and a second blade. The second oil screen is located on the side of the first oil screen 111 away from the drive member 2. The first oil screen 111 and the second oil screen are stacked on top of each other, further improving the filtration effect of the oil screen structure. The combined action of the first blade 112 and the second blade further improves the oil fume extraction effect of the flue. Specifically, the first rotating oil screen 11 and the second rotating oil screen 12 have the same structure.
[0045] Optionally, the oil mesh structure also includes a fixing ring 3 and an oil storage shell 4. The peripheral wall of the fixing ring 3 is divided into a first part 31 and a second part 32 along the axis of the fixing ring 3. The first part 31 is provided with an oil throwing hole 311, and the second part 32 is provided with a filter hole 321. The rotating component 1 is located in the first part 31. The second part 32 is arranged opposite to the opening of the oil storage shell 4. In this embodiment, the fixing ring 3 is inserted vertically into the flue. The oil fumes enter the first part 31 of the fixing ring 3, then pass through the rotating component 1 into the second part 32, and finally drift out from the filter hole 321 on the second part 32. When the flue gas passes through the rotating assembly 1, the rotating assembly 1 throws some of the filtered oil onto the first part 31. When the flue gas passes through the filter hole 321 on the second part 32, the remaining oil in the flue gas adheres to the second part 32. Since the fixing ring 3 is inserted vertically into the flue, the oil on the first part 31 and the second part 32 flows from the opening of the oil storage shell 4 into the oil storage cavity under the action of gravity, so as to slow down the pollution rate of the fans and other equipment in the flue.
[0046] Specifically, multiple oil-slinging holes 311 are provided, and the multiple oil-slinging holes 311 are arranged circumferentially around the fixing ring 3 on the first part 31. Multiple filter holes 321 are provided, and the multiple filter holes 321 are arranged circumferentially around the fixing ring 3 on the second part 32.
[0047] Optionally, the drive component 2 is disposed inside the oil reservoir 4 and fixedly connected to the oil reservoir 4. In this embodiment, compared to disposing the drive component 2 outside the oil reservoir 4, this arrangement can reduce the overall size of the oil mesh structure and simplify the fixing method of the drive component 2.
[0048] Optionally, the drive component 2 includes a motor 21 and an oil-proof sleeve 22. The oil-proof sleeve 22 is fixedly connected to the oil reservoir 4, and the motor 21 is inserted into the oil-proof sleeve 22 and fixed relative to it. In this embodiment, since the oil reservoir 4 stores filtered oil, an oil-proof sleeve 22 is provided to prevent the oil from corroding the motor 21 and affecting its normal operation. This isolates the motor 21 from the oil, preventing corrosion of the motor 21 and ensuring its normal operation.
[0049] Optionally, the oil-proof sleeve 22 is made of aluminum alloy, which is better at preventing oil corrosion than rubber.
[0050] Optionally, the oil-proof sleeve 22 is fixed to the oil reservoir 4 by snap-fit or screw connection, and the oil-proof sleeve 22 is interference-fitted with the motor 21.
[0051] Optionally, a rotating gear 211 is coaxially fixed on the shaft of the motor 21, and a rotating gear ring 1111 is provided on the first oil screen 111. The rotating gear 211 is inserted into the rotating gear ring 1111, and any one of the external teeth of the rotating gear 211 is inserted between two adjacent internal teeth of the rotating gear ring 1111, so as to realize that the rotating gear 211 and the rotating gear ring 1111 rotate synchronously, so as to realize that the motor 21 drives the first oil screen 111 to rotate.
[0052] In other embodiments, a spline can be provided on the shaft of the motor 21, and a spline groove can be provided on the first oil screen 111, with the spline inserted into the spline groove so that the motor 21 drives the first rotating oil screen 11 to rotate.
[0053] Optionally, the oil storage tank 4 is provided with an open oil storage cavity, and the second part 32 passes through the open cavity and extends into the oil storage cavity. In this embodiment, this arrangement allows the oil on the inner wall of the first part 31 and the oil on the inner wall of the second part 32 to flow into the storage cavity under the action of gravity.
[0054] Optionally, the open portion of the oil storage shell 4 is provided with an annular inner flange 41, which abuts against the second part 32. Multiple oil guide holes 42 communicating with the oil storage cavity are sequentially spaced along the circumference of the annular inner flange 41. In this embodiment, the oil in the fumes adheres to the outer wall of the first part 31 and the outer wall of the second part 32. Under the action of its own gravity, the oil flows to the annular inner flange 41 and finally flows into the oil storage cavity from the oil guide holes 42 of the annular inner flange 41.
[0055] Optionally, the oil guide hole 42 is arc-shaped. In this embodiment, this setting can maximize the size of the oil guide hole 42 to facilitate the flow of oil on the annular inner flange 41 into the oil storage cavity through the oil guide hole 42.
[0056] Optionally, the distance between the annular inner flange 41 and the bottom wall of the oil reservoir 4 gradually decreases as the flange approaches the fixing ring 3 radially. In this embodiment, this arrangement can prevent the oil on the annular inner flange 41 from flowing away from the outer peripheral wall of the oil reservoir 4.
[0057] In other embodiments, an annular inner flange 41 is provided with an annular ridge coaxial with the annular inner flange 41, and an oil guide hole 42 is located inside the annular ridge. The annular ridge can prevent the oil on the annular inner flange 41 from flowing away from the outer peripheral wall of the oil storage shell 4.
[0058] Optionally, the oil mesh structure further includes an oil-water filter membrane, which is attached to the outer peripheral wall of the fixing ring 3 and blocks the oil-throwing hole 311 and the filter hole 321. In this embodiment, when the oil thrown out by the rotating component 1 passes through the oil-throwing hole 311, the oil-water filter membrane blocks this portion of the oil. The oil and water passing through the oil-throwing hole 311 will flow along the outer wall of the fixing ring 3 into the lower oil guide hole 42, and then into the oil storage cavity. When the oil fumes pass through the filter hole 321, the oil-water filter membrane blocks the oil in this portion of the oil fumes. The oil and water passing through the filter hole 321 will flow along the outer wall of the fixing ring 3 into the lower oil guide hole 42, and then into the oil storage cavity.
[0059] Optionally, the oil mesh structure further includes a fixed oil mesh 5, which is disposed within the first part 31 and located on the side of the first rotating oil mesh 11 away from the second part 32. In this embodiment, the fixed oil mesh 5 can serve as a primary filter, and the filtered oil falls onto the rotating assembly 1 under the action of gravity, and is then thrown onto the first part 31 by the rotating assembly 1.
[0060] Optionally, the mesh size of the fixed oil screen 5 is larger than that of the first rotating oil screen 11, and the mesh size of the fixed oil screen 5 is larger than that of the second rotating oil screen 12. In this embodiment, the fixed oil screen 5 only filters larger oil and water vapor particles. Because its mesh size is larger, it will not have a significant impact on the throughput of oil fumes. Furthermore, since the fixed oil screen 5 is located on the outermost side, it is convenient for users to wipe, thereby ensuring the throughput of oil fumes.
[0061] This embodiment also provides an island-style range hood, including the oil mesh structure described above. The island-style range hood includes a flue, and the oil fume structure is disposed within the flue.
