Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an oil filter assembly and an integrated stove. Background Technology

[0002] Integrated cooktops are an essential appliance in modern homes, effectively removing cooking fumes and harmful gases, cleaning the kitchen environment, and enhancing the cooking experience. Current integrated cooktops are equipped with an oil filter assembly. As cooking fumes pass through the filter, they come into contact with it, allowing some of the heat to be absorbed. This condensation and filtration of the fumes achieves grease separation, reducing the amount of fumes emitted.

[0003] Existing integrated stoves have oil filter components that include both single-layer and multi-layer oil filters. Multi-layer oil filters can significantly improve the separation effect of oil fumes compared to single-layer oil filters. However, for multi-layer oil filters, the oil filter usually uses a mesh with a constant pore size, which affects the smoothness of the smoke passing through, thus affecting the smoke exhaust effect, and can also easily cause excessive noise. Utility Model Content

[0004] The purpose of this utility model is to provide an oil mesh assembly and an integrated stove to improve the smoothness of flue gas passing through the oil mesh assembly and reduce noise.

Each first mesh opening has a first inlet for oil fumes to enter and a first outlet for oil fumes to exit. The cross-sectional area of ​​the first mesh openings gradually decreases from the first inlet to the first outlet.

[0008] The second oil mesh is installed on the mounting frame and is spaced apart from the first oil mesh. The second oil mesh includes a plurality of spaced second mesh holes. The second mesh holes have a second inlet for oil fumes to enter and a second outlet for oil fumes to exit.

[0022] The oil mesh assembly provided by this utility model has at least the following beneficial effects:

[0023] The oil filter assembly includes a mounting frame, and a first oil filter and a second oil filter, both mounted on the mounting frame. The second oil filter and the first oil filter are spaced apart. The first oil filter includes a plurality of spaced first mesh openings, and the second oil filter includes a plurality of spaced second mesh openings. The first mesh openings have a first inlet for oil fumes to enter and a first outlet for oil fumes to exit. The cross-sectional area of ​​the first mesh openings gradually decreases from the first inlet to the first outlet. The second mesh openings have a second inlet for oil fumes to enter and a second outlet for oil fumes to exit. The cross-sectional area of ​​the second mesh openings gradually decreases from the second inlet to the second outlet. This makes both the first and second mesh openings have a constricted structure, which can improve the guiding effect of the passing oil fumes, thereby improving the oil fume exhaust effect. At the same time, the hole walls of the first and second mesh openings have enhanced sound wave reflection effects, which can effectively reduce noise.

[0045] 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.

[0046] This embodiment provides an integrated stove that integrates multiple functions such as range hood, cooktop, disinfection cabinet, and steam oven. This integrated stove can be applied to catering establishments, such as kitchens and hotels.

[0047] Please refer to Figures 1 to 4The integrated stove includes a body 10, a burner head 20, an air box 301, a fan 302, a burner 40, and an oil filter assembly 50. The burner head 20 and burner 40 are both located above the body 10. The air box 301 is located inside the body 10, and the fan 302 is located inside the air box 301. The burner head 20 has a smoke extraction channel 202 and a smoke inlet 201 communicating with the smoke extraction channel 202. The smoke extraction channel 202 communicates with the air inlet of the air box 301. The mounting bracket 1 of the oil filter assembly 50 is fixed to the cavity wall of the smoke extraction channel 202 or the air box 301. The burner 40 heats the stove, allowing food to be cooked. Under the negative pressure provided by the fan 302, the fumes generated during cooking enter the smoke extraction channel 202 through the smoke inlet 201, pass through the oil filter assembly 50 into the air box 301, and are then discharged from the integrated stove by the fan 302. When the fumes pass through the oil filter assembly 50, some of the heat of the fumes is absorbed by the oil filter assembly 50, which in turn causes the fumes to be condensed and filtered by the oil filter assembly 50, achieving the effect of oil separation and reducing the amount of fumes emitted.

[0048] In this embodiment, an oil mesh assembly 50 is provided as an example, which allows the oil separated by the oil mesh assembly 50 to drip directly into the air box 301. Preferably, the oil mesh assembly 50 is installed at one end of the air box 301 near the smoke extraction channel 202. In other embodiments, the oil mesh assembly 50 may also be disposed within the smoke extraction channel 202.

[0049] Optionally, the body 10 is also provided with a smoke exhaust port 101. Driven by the fan 302, the fumes enter the air box 301 from the smoke extraction channel 202 and are discharged from the smoke exhaust port 101 under the drive of the fan 302. The output end of the fan 302 and the smoke exhaust port 101 can be connected by a corrugated pipe, or the output end of the fan 302 can pass through the smoke exhaust port 101 and partially extend out of the body 10.

[0050] Optionally, the integrated stove also includes a knob 80 located on the body 10, which is used to control the firepower of the burner 40. It should be noted that the number of burners 40 can be set according to actual needs, for example, it can be set to one, two or three, etc. Correspondingly, the number of knobs 80 is set to be the same as the number of burners 40, and the two are set one-to-one.

[0051] Optionally, the integrated stove also includes a gas inlet port 110 disposed on the body 10. The gas inlet port 110 is used to connect to the gas supply pipeline and to supply gas to the burner 40.

[0052] Optionally, the integrated stove also includes feet 60 located below the body 10, and a kick plate 70 located below the body 10 and at the front of the body 10. The integrated stove is supported on the ground by the feet 60, and the kick plate 70 covers the feet 60 behind it to maintain the aesthetics of the integrated stove.

[0053] Optionally, the integrated cooktop also includes a steam oven 120 integrated into the body 10, and a control panel 90 disposed on the body 10, the control panel 90 being used to operate the steam oven 120. In other embodiments, the steam oven 120 can also be replaced by a disinfection cabinet, oven, steamer, etc.

[0054] Optionally, the integrated cooktop also includes an oil collection box 100 located at the bottom of the body 10, which is used to collect the oil collected in the steam oven 120 and the air box 301.

[0055] Please refer to Figure 2 , Figures 4 to 9 In this embodiment, the oil mesh assembly 50 includes a mounting frame 1, a first oil mesh 2, and a second oil mesh 3. Both the first oil mesh 2 and the second oil mesh 3 are mounted on the mounting frame 1. The second oil mesh 3 and the first oil mesh 2 are spaced apart. The first oil mesh 2 includes a plurality of spaced first mesh holes 21, and the second oil mesh 3 includes a plurality of spaced second mesh holes 31. When the oil fumes pass through the oil mesh assembly 50, the oil fumes first pass through the first mesh holes 21 and then through the second mesh holes 31. The oil fumes can come into contact with the first oil mesh 2 and the second oil mesh 3 respectively, so that the oil fumes can be fully cooled and the oil fume separation effect is improved.

[0056] In this embodiment, an exemplary scheme is provided in which the second oil mesh 3 and the first oil mesh 2 are spaced apart in the vertical direction, as shown in the example. Figure 2 In other embodiments, the direction indicated by the middle arrow ab can also be set to other directions according to actual needs, such as the spacing between the first oil mesh 2 and the second oil mesh 3.

[0057] In addition, the oil filter assembly 50 is not limited to integrated stoves, but can also be used in kitchen appliances such as top-mounted range hoods and side-mounted range hoods.

[0058] In the prior art, the oil mesh of the oil mesh assembly usually uses a mesh with a constant aperture, which affects the smoothness of airflow and is prone to excessive noise.

[0059] For this, please refer to Figure 7In this embodiment, the first mesh 21 has a first inlet 213 for the entry of oil fumes and a first outlet 214 for the discharge of oil fumes. The cross-sectional area of ​​the first mesh 21 gradually decreases from the first inlet 213 to the first outlet 214. The second mesh 31 has a second inlet 313 for the entry of oil fumes and a second outlet 314 for the discharge of oil fumes. The cross-sectional area of ​​the second mesh 31 gradually decreases from the second inlet 313 to the second outlet 314. Specifically, when oil fumes pass through the oil mesh assembly 50, the oil fumes enter the corresponding first mesh 21 from each first inlet 213 and are discharged from the corresponding first outlet 214, and then enter the corresponding second mesh 31 from each second inlet 313 and are discharged from the corresponding second outlet 314. Because the cross-sectional area of ​​the first mesh 21 gradually decreases from the first input port 213 to the first output port 214, and the cross-sectional area of ​​the second mesh 31 gradually decreases from the second input port 313 to the second output port 314, both the first mesh 21 and the second mesh 31 have a constricted structure. Thus, both the first mesh 21 and the second mesh 31 can guide the flow of oil fumes, allowing the airflow to be smoothed when the oil fumes pass through the first oil mesh 2 and the second oil mesh 3, thereby improving the oil fume exhaust effect. In addition, the constricted structure of both the first mesh 21 and the second mesh 31 also enhances the sound wave reflection effect of the hole walls of the first mesh 21 and the second mesh 31, effectively reducing noise.

[0060] Alternatively, please refer to Figure 2 , Figure 5 and Figure 8 In this embodiment, the plurality of first mesh openings 21 of the first oil mesh 2 are along a first direction (the first direction is as follows). Figure 2 The second mesh 3 has multiple second mesh openings 31 spaced apart along a first direction (in the direction indicated by the middle arrow cd). The first direction is perpendicular to the vertical direction. In other embodiments, the multiple first mesh openings 21 can also be arranged in a multi-row, multi-column array, and / or, the multiple second mesh openings 31 can also be arranged in a multi-row, multi-column array.

[0061] Optionally, the plurality of first mesh openings 21 of the first oil mesh 2 are distributed at equal intervals along the first direction, and the plurality of second mesh openings 31 of the second oil mesh 3 are distributed at equal intervals along the first wind direction. This arrangement ensures that the oil fumes remain balanced along the first direction when passing through the oil mesh assembly 50.

[0062] Optionally, in this embodiment, both the first mesh 21 and the second mesh 31 are elongated meshes and are wedge-shaped. Specifically, in this embodiment, the width direction of the first mesh 21 and the width direction of the second mesh 31 are both along a first direction, and the length direction of the first mesh 21 and the length direction of the second mesh 31 are both along a second direction (the second direction is as follows). Figure 2(As indicated by the arrow ef), the first direction, the second direction, and the vertical direction are perpendicular to each other. In other embodiments, the first mesh 21 can also be configured as a circular conical hole or other shape as needed, and / or the second mesh 31 can also be configured as a circular conical hole or other shape as needed.

[0063] Specifically, in this embodiment, the first oil mesh 2 includes a plurality of first ribs 22, which are spaced apart along a first direction. The length direction of the first ribs 22 is along a second direction, and the width direction of the first ribs 22 is along the first direction. Both ends of the length direction of each first rib 22 are connected to the mounting bracket 1. Along the first direction, a first mesh 21 is formed between any two adjacent first ribs 22. Since the first mesh 21 is a long wedge-shaped hole, the first ribs 22 are also wedge-shaped. In the vertical direction, the width of the first ribs 22 gradually increases from top to bottom, so that the width of the first mesh 21 formed between two adjacent first ribs 22 gradually decreases from top to bottom. When the oil fumes come into contact with the first ribs 22, they can be smoothly guided into the first mesh 21 on both sides.

[0064] The second oil mesh 3 includes multiple second ribs 32, which are spaced apart along a first direction. The length direction of the second ribs 32 is along a second direction, and the width direction of the second ribs 32 is along the first direction. Both ends of the length direction of each second rib 32 are connected to the mounting bracket 1. A second mesh 31 is formed between any two adjacent second ribs 32. Since the second mesh 31 is a long, wedge-shaped hole, the second ribs 32 are also wedge-shaped. In the vertical direction, the width of the second ribs 32 gradually increases from top to bottom along the first direction, so that the width of the second mesh 31 formed between two adjacent second ribs 32 gradually decreases from top to bottom. When oil fumes come into contact with the second ribs 32, they can be smoothly guided into the second mesh 31 on both sides.

[0065] In other embodiments, the first ribs 22 of the first oil mesh 2 can also be indirectly mounted to the mounting frame 1. Specifically, the first oil mesh 2 further includes a first frame, and each of the first ribs 22 is fixed to the first frame, which is mounted to the mounting frame 1; the second ribs 32 of the second oil mesh 3 can also be indirectly mounted to the mounting frame 1. Specifically, the second oil mesh 3 further includes a second frame, and each of the second ribs 32 is fixed to the second frame, which is mounted to the mounting frame 1.

[0066] It should be noted that although this embodiment specifically provides a double-layer oil mesh structure including a first oil mesh 2 and a second oil mesh 3, this should not be interpreted as limiting the number of layers of oil mesh included in the oil mesh assembly 50. In other embodiments, the number of layers of oil mesh included in the oil mesh assembly 50 can also be set according to actual needs. For example, the oil mesh assembly 50 also includes a third oil mesh located below the second oil mesh 3. The third oil mesh is installed on the mounting frame 1 and is located below the second oil mesh 3. The third oil mesh includes a plurality of spaced third mesh holes. The third mesh holes have a third inlet for oil fumes to enter and a third outlet for oil fumes to exit. The cross-sectional area of ​​the third mesh holes gradually decreases from the third inlet to the third outlet.

[0067] Alternatively, please refer to Figure 7 Multiple first meshes 21 and multiple second meshes 31 are sequentially and alternately distributed along a first direction. For details, please refer to... Figure 6 In this embodiment, along the first direction, a plurality of first mesh openings 21 and a plurality of second mesh openings 31 are arranged sequentially in the order of first mesh opening 21, second mesh opening 31, first mesh opening 21, second mesh opening 31, ... The number of first mesh openings 21 in the first oil mesh 2 is equal to the number of second ribs 32 in the second oil mesh 3, and the plurality of first mesh openings 21 and the plurality of second ribs 32 are arranged in a one-to-one correspondence along the vertical direction. This configuration ensures that when the fumes reach the first oil mesh 2, they first come into contact with and are cooled by multiple first ribs 22. Each first rib 22 diverts the fumes into two adjacent first mesh openings 21, allowing the fumes to be guided into multiple airflow streams after passing through the first oil mesh 2. These airflow streams are directed towards the second ribs 32 of the second oil mesh 3 below, enabling the fumes to fully contact and be further cooled. Each second rib 32 diverts the airflow streams flowing towards it into two adjacent second mesh openings 31, ensuring that the fumes are also guided into multiple airflow streams when passing through the second oil mesh 3 and entering the lower air box 301. This guarantees the smooth flow of fumes through the oil mesh assembly 50. Furthermore, along the direction of the fumes' airflow, the noise generated by the fumes can be directly blocked by the second ribs 32 after exiting the first mesh openings 21, effectively improving the noise reflection effect and further reducing noise.

[0068] Alternatively, please refer to Figure 7The first mesh 21 includes a first hole wall 211 and a second hole wall 212 spaced apart and arranged at an included angle. The distance between the first hole wall 211 and the second hole wall 212 gradually decreases from the first input port 213 to the first output port 214. The included angle between the first hole wall 211 and the second hole wall 212 is d1, where 20°≤d1≤70°. This arrangement ensures that the second mesh 31 effectively guides the airflow of oil fumes and reduces noise. Specifically, the value of d1 can be 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, or 70°, etc. Preferably, the length dimension of the first mesh 21 remains constant from the first input port 213 to the first output port 214. Of course, in other embodiments, the length dimension of the first mesh 21 can also gradually decrease from the first input port 213 to the first output port 214.

[0069] Optionally, in this embodiment, both the first hole wall 211 and the second hole wall 212 are planar. In other embodiments, the first hole wall 211 and the second hole wall 212 may also be set as curved surfaces as needed.

[0070] Alternatively, please refer to Figure 7The second mesh 31 includes a third hole wall 311 and a fourth hole wall 312 spaced apart and arranged at an angle. The distance between the third hole wall 311 and the fourth hole wall 312 gradually decreases from the second input port 313 to the second output port 314. The angle between the third hole wall 311 and the fourth hole wall 312 is d2, where 20°≤d2≤70°. This arrangement ensures that the second mesh 31 can guide the flow of oil fume and reduce noise. Specifically, the value of d2 can be 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 51°, 52°, 53°, 54°, 55°, 56°, 57°, 58°, 59°, 60°, 61°, 62°, 63°, 64°, 65°, 66°, 67°, 68°, 69°, or 70°, etc. Preferably, the length dimension of the second mesh 31 remains constant from the second input port 313 to the second output port 314. Of course, in other embodiments, the length dimension of the second mesh 31 can also gradually decrease from the second input port 313 to the second output port 314.

[0071] Optionally, in this embodiment, the third hole wall 311 and the fourth hole wall 312 are both planar. In other embodiments, the first hole wall 211 and the second hole wall 212 can also be set as curved surfaces as needed.

[0072] Alternatively, please refer to Figure 9 The angle between the first oil mesh 2 and the horizontal plane is α, where 0° ≤ α ≤ 30°. This arrangement ensures that when α equals 0°, the flow direction of the oil fumes within the smoke extraction channel 202 is perpendicular to the first oil mesh 2, facilitating processing; when α is greater than 0°, the flow direction of the oil fumes within the smoke extraction channel 202 forms an angle with the first oil mesh 2, guaranteeing that the oil separated by the first oil mesh 2 drips down the inclined angle into the lower air box 301. Furthermore, when the first oil mesh 2 is inclined relative to the horizontal plane, the total contact area between the first oil mesh 2 and the oil fumes is increased, ensuring effective oil fume separation.

[0073] Alternatively, please refer to Figure 9The angle between the second oil mesh 3 and the horizontal plane is β, where 0°≤β≤50°.

[0074] Alternatively, please refer to Figure 9 The included angle between the first oil mesh 2 and the second oil mesh 3 is γ, where 0°≤γ≤50°. When γ equals 0°, the first oil mesh 2 and the second oil mesh 3 are set in parallel. When γ is greater than 0°, the first oil mesh 2 and the second oil mesh 3 form an included angle. The specific values ​​of γ can be 0°, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, or 50°, etc.

[0075] Alternatively, please refer to Figure 9 The distance between the first oil mesh 2 and the second oil mesh 3 is L, where 10mm ≤ L ≤ 20mm. This distance refers to the minimum distance between the first oil mesh 2 and the second oil mesh 3. This setting ensures that the air intake of the first oil mesh 2 and the second oil mesh 3 meets the requirements. The specific value of L can be 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, or 20mm, etc.

[0076] Alternatively, please refer to Figure 5 and Figure 8 The mounting bracket 1 includes a mounting boss 11, which has mounting holes 111. A connector passes through the mounting holes 111 and connects to the air box 301 to install the oil filter assembly 50. Preferably, the air box 301 is provided with a limiting block. The connector can be a bolt, screw, rivet, etc. Taking a screw as an example, the connector passes through the mounting hole 111 and is threadedly connected to the limiting block. More preferably, the mounting bracket 1 includes two mounting bosses 11, which are respectively located at both ends of the mounting bracket 1 in a first direction. Each mounting boss 11 is provided with a mounting hole 111. The air box 301 is provided with two limiting blocks. Two screws pass through the two mounting holes 111 and are threadedly connected to the two limiting blocks.

[0077] Alternatively, please refer to Figure 5 The first oil mesh 2, the second oil mesh 3, and the mounting frame 1 are integrally formed. This design reduces the number of parts and facilitates the installation and maintenance of the oil mesh assembly 50. The oil mesh assembly 50 can be manufactured using casting, CNC machining, or 3D printing technology. In other embodiments, the first oil mesh 2 and the mounting frame 1 can be detachably connected, and the second oil mesh 3 can be detachably connected to the mounting frame 1, as needed.

[0078] As an alternative, at least one of the first oil filter 2 and the second oil filter 3 is movably connected to the mounting bracket 1. This arrangement allows the noise reduction effect and airflow of the oil filter assembly 50 to be adjustable, thereby allowing the position of the first oil filter 2 and / or the second oil filter 3 to be adjusted according to the cooking conditions to regulate noise and airflow.

[0079] Specifically, this embodiment exemplarily provides a scheme in which the first oil mesh 2 is fixedly connected to the mounting frame 1, and the second oil mesh 3 is movably connected to the mounting frame 1. The second oil mesh 3 and the mounting frame 1 can be rotatably connected. When the second oil mesh 3 and the mounting frame 1 are rotatably connected, the second oil mesh 3 also includes a second frame, with each of the second ribs 32 of the second oil mesh 3 fixed to the second frame. The second frame is fixedly provided with a rotating shaft, which is rotatably connected to the mounting frame 1. A motor directly or indirectly drives the rotating shaft to rotate, thereby allowing the second oil mesh 3 to rotate relative to the mounting frame 1 and the first oil mesh 2. Preferably, the rotating shaft is centrally located on the mounting frame 1 along a second direction. The second oil mesh 3 and the mounting frame 1 can also be slidably connected. When the second oil mesh 3 and the mounting frame 1 are slidably connected, the second oil mesh 3 also includes a second frame, with each of the second ribs 32 of the second oil mesh 3 fixed to the second frame. The second frame can slide relative to the mounting frame 1 in a vertical direction, thereby adjusting the distance between the first oil mesh 2 and the second oil mesh 3. The second oil mesh 3 can be driven to slide relative to the first oil mesh 2 by components such as electric actuators and cylinders.

[0080] In other embodiments, the first oil mesh 2 may be movably connected to the mounting frame 1, and the second oil mesh 3 may be fixedly connected to the mounting frame 1, as needed; or, both the first oil mesh 2 and the second oil mesh 3 may be movably connected relative to the mounting frame 1. The movable connection between the first oil mesh 2 and the mounting frame 1 can be achieved by rotating the first oil mesh 2 relative to the mounting frame 1, or by sliding the first oil mesh 2 relative to the mounting frame 1 in a vertical direction.

[0081] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
