Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and particularly to a deep-well type oil fume separation system with a condensate plate structure. Background Art

[0002] A range hood is an indispensable device in modern kitchens. Its core function is to efficiently suck the oil fumes generated during cooking to purify the kitchen air. As a key front-end component of the range hood, the oil fume separator undertakes a crucial task: physically separating pollutants such as grease droplets and fine particles in the oil fume airflow, and aggregating and guiding them to the oil collection tank for collection. This process effectively prevents oil stains from directly entering the fan system and the inner cavity of the range hood, which is decisive for protecting the fan performance, reducing the accumulation of internal oil scale, maintaining the long-term stable operation of the device, and reducing the difficulty of cleaning and maintenance.

[0003] Currently, the most widely used structure of the oil fume separator on the market is the double-layer splicing design of front and rear wire frames. Such a design usually adopts a planar or nearly planar structure, and its main advantage is that the structure is relatively simple, which is convenient for users to disassemble, clean and install. However, this planar structure has obvious technical limitations: the suction angle is single and the effective air inlet area is relatively limited. When the amount of oil fumes generated is large or there is an instantaneous explosion, the oil fume airflow is likely to escape directly from above or around the separator because it cannot be sucked in time and sufficiently, resulting in a decrease in the suction rate and pollution of the kitchen environment.

[0004] In order to overcome the above defects of the planar separator and improve the oil fume capture efficiency, the deep-well type oil fume separator has emerged in the development of industry technology, such as the structure disclosed in Chinese invention patent CN221788554U. The remarkable feature of such a design is that the main body of its oil mesh forms an obvious depression inward (towards the air inlet direction of the range hood), constituting a "concave cavity" or "deep well" structure. This structure innovatively expands the three-dimensional windward surface and the effective oil absorption area of the oil mesh, providing more diversified inhalation paths for the oil fume airflow. More importantly, the concave cavity structure can more effectively "catch" the rising oil fumes, significantly suppressing the tendency of the oil fumes to overflow and escape from above the separator, thereby improving the overall oil fume separation and capture effect at the source.

[0005] The layout space of the oil fume separator with a double-layer splicing design of front and rear wire frames is limited. How to further improve the oil fume separation effect within the limited space is the key design point of the oil fume separator. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a deep-well type oil fume separation system with a condensate plate structure.

[0007] An embodiment of the present invention solves its technical problem by adopting a technical solution: a deep-well oil fume separation system with a condensation plate structure, comprising a front mesh frame and a rear mesh frame; the front mesh frame and the rear mesh frame can form an oil fume separation mesh group; the oil fume separation mesh group is recessed toward the side away from the user to form a recessed cavity; smoke cage side panels are provided on both lateral sides of the oil fume separation mesh group; the oil fume separation mesh group is provided with a detachable condensation plate, the condensation plate is located in front of the recessed cavity; the outer periphery of the condensation plate is spaced from at least one side of the circumference of the recessed cavity to form a condensation air gap;

[0008] The smoke cage side panels on both sides are integrally formed with the front net frame or the rear net frame, and are surrounded by the upper and lower sides of the front net frame or the rear net frame to form a flat frame-shaped installation frame structure; an oil collecting part is provided on the lower side of the installation frame structure; and an oil leakage hole is opened in the oil collecting part.

[0009] Optionally, an upper connecting seat is provided above the front screen frame and / or the rear screen frame; and the upper side of the condensation plate is detachably mounted on the upper connecting seat.

[0010] Optionally, a lower connecting seat is provided below the front mesh frame and / or the rear mesh frame; the lower side of the condensation plate is detachably mounted on the lower connecting seat; or, the lower side of the condensation plate is mounted on the lower connecting seat.

[0011] Optionally, a connecting plate is provided on the back of the condensing plate; the connecting plate is used to connect the upper connecting seat or the lower connecting seat.

[0012] Optionally, a connecting piece is provided between the connecting plate and the upper connecting seat and / or the lower connecting seat.

[0013] Optionally, the connecting member is a pin, a bolt or a hinge structure; or, the connecting member is a damping hinge or a damping rotating shaft.

[0014] Optionally, the lower side of the condensation plate is located above the oil collecting portion and does not extend beyond the front side of the installation frame.

[0015] Optionally, the condensation plate is provided with long strip-shaped air passage slots.

[0016] Optionally, the air duct is arc-shaped, straight-line-shaped or a combination of the two.

[0017] Optionally, the front mesh frame is provided with a handle, and an escape groove is provided above the condensation plate for accommodating the handle.

[0018] Advantages of the present invention: The condensation plate is arranged directly in front of the concave cavity to directly intercept the oil fume airflow preliminarily separated by the deep well structure. After the high-temperature oil mist in the oil fume contacts the low-temperature condensation plate, it quickly condenses and liquefies, causing the suspended fine oil droplets to aggregate and adhere to the plate surface, achieving efficient capture of oil pollutants. This design significantly improves the separation ability of oil droplets. The condensation air passage gap allows the airflow to pass smoothly on the one hand, and on the other hand, forces the airflow to generate a turbulence effect when passing through the narrow gap, increasing the contact frequency and contact time between the oil fume and the condensation plate and the oil mesh wall surface, thereby maximizing the condensation effect. The condensation plate is arranged closely in front of the concave cavity, making full use of the original three-dimensional space of the deep well separator, without the need to additionally increase the overall thickness or occupy external space, and perfectly adapting to the compact installation requirements of the front and rear frame splicing design. The deep well structure is responsible for capturing and guiding the main oil fume over a large area and at multiple angles, while the condensation plate is responsible for dealing with the escaping fine oil mist. The two form an efficient cooperation in terms of spatial position and function. The grease collected by the condensation plate can flow down its surface into the oil collection part below or flow into the main oil collection system along the diversion path of the concave cavity to ensure smooth grease recovery path; the integrally formed side plates eliminate the assembly gaps, enhance the overall anti-deformation ability, and withstand the long-term high-temperature and high-humidity environment. The oil collection part accurately receives the grease dripping from the condensation plate and the deep cavity, and the oil leakage hole leads directly to the external oil cup to avoid dripping pollution.

[0031] Embodiment

[0032] Refer to Figures 1 to 4, a deep-well type oil fume separation system with a condenser plate 40 structure proposed by the present invention includes a front frame 10 and a rear frame 20; the front frame 10 and the rear frame 20 can form an oil fume separation net group; the oil fume separation net group is recessed towards the side away from the user to form a recessed cavity; cage-shaped side plates 30 are arranged on the lateral sides of the oil fume separation net group; the oil fume separation net group is provided with a detachable condenser plate 40, and the condenser plate 40 is located in front of the recessed cavity; at least one side of the periphery of the condenser plate 40 is spaced from the circumferential direction of the recessed cavity to form a condensation air passage gap 50;

[0033] The cage-shaped side plates 30 on both sides are integrally formed with the front frame 10 or the rear frame 20, and enclose with the upper and lower sides of the front frame 10 or the rear frame 20 to form a planar frame-shaped installation frame structure 70; an oil collection part 71 is arranged on the lower side of the installation frame structure 70; an oil leakage hole 72 is opened in the oil collection part 71.

[0034] In the present invention, the condenser plate 40 is arranged directly in front of the recessed cavity to directly intercept the oil fume airflow preliminarily separated by the deep-well structure. The high-temperature oil mist in the oil fume quickly condenses and liquefies after contacting the low-temperature condenser plate 40, causing the suspended fine oil droplets to aggregate and adhere to the plate surface, realizing the efficient capture of oil pollutants. This design significantly improves the separation ability of oil droplets. On the one hand, the condensation air passage gap 50 allows the air flow to pass smoothly, and on the other hand, it forces the air flow to generate a turbulence effect when passing through the narrow gap, increasing the contact frequency and contact time between the oil fume and the condenser plate 40 and the oil net wall surface, thereby maximizing the condensation effect. The condenser plate 40 is arranged closely against the front of the recessed cavity, making full use of the original three-dimensional space of the deep-well separator, without the need to additionally increase the overall thickness or occupy external space, and perfectly adapting to the compact installation requirements of the split design of the front and rear frames 20. The deep-well structure is responsible for capturing and guiding the main oil fume in a large area and at multiple angles, while the condenser plate 40 is responsible for dealing with the escaping fine oil mist. The two form an efficient cooperation in terms of spatial position and function. The grease collected by the condenser plate 40 can flow along its surface into the oil collection part 71 below or flow into the main oil collection system along the guiding path of the recessed cavity to ensure a smooth grease recovery path; the integrally formed side plates eliminate the assembly gaps, enhance the overall anti-deformation ability, and withstand the long-term high-temperature and high-humidity environment. The oil collection part 71 accurately receives the grease dripping from the condenser plate 40 and the deep cavity, and the oil leakage hole 72 leads directly to the external oil cup to avoid dripping and pollution.

[0035] In this embodiment, an upper connecting seat 60 is arranged above the front frame 10 and / or the rear frame 20; the upper side of the condenser plate 40 is detachably installed on the upper connecting seat 60. The "suspended" fixation of the condenser plate 40 is realized through the upper connecting seat 60, greatly improving the maintenance convenience. The self-weight of the condenser plate 40 naturally sags, ensuring a tight fit with the upper connecting seat 60 and reducing vibration and abnormal noise.

[0036] Further, a lower connecting seat 61 is provided below the front frame 10 and / or the rear frame 20; the lower side of the condensation plate 40 is detachably mounted on the lower connecting seat 61; alternatively, the lower side of the condensation plate 40 is placed on the lower connecting seat 61. The lower connecting seat 61 and the upper connecting seat 60 cooperate to form an "upper and lower double anchor point" fixed structure, suppressing the shaking of the condensation plate 40 caused by air flow impact and ensuring the stability of the air passing gap.

[0037] In this embodiment, a connecting plate 41 is provided on the back of the condensation plate 40; the connecting plate 41 is used to connect the upper connecting seat 60 or the lower connecting seat 61. The connecting plate 41 serves as a transition structure, evenly transmitting the wind pressure received by the condensation plate 40 to the frame skeleton, avoiding local deformation and extending the service life. The standardized connecting plate 41 interface can adapt to different models of the condensation plate 40, realizing a flexible configuration of "one frame with multiple plates" and reducing production costs.

[0038] In this embodiment, a connecting member is provided between the connecting plate 41 and the upper connecting seat 60 and / or the lower connecting seat 61.

[0039] In some embodiments, the connecting member is a pin shaft, a bolt or a hinge structure. The pin shaft or the bolt provides rigid fixation and is suitable for high-wind-pressure models to ensure zero loosening. The hinge structure supports the upward flipping of the condensation plate 40, facilitating the wiping of the accumulated oil on the back.

[0040] In some embodiments, the connecting member is a damping hinge or a damping rotating shaft. It realizes the slow descending and opening / closing of the condensation plate 40, avoiding rapid bouncing and hitting the frame, and improving the operation safety and component durability.

[0041] In this embodiment, the two side cage smoke plates 30 are integrally formed on the front frame 10 or the rear frame 20, and together with the upper and lower sides of the front frame 10 or the rear frame 20, they enclose a planar frame-shaped installation frame structure 70; an oil collecting part 71 is provided on the lower side of the installation frame structure 70; the oil collecting part 71 is provided with an oil leakage hole 72. The integrally formed side plates eliminate the assembly gaps, enhance the overall anti-deformation ability, and withstand the long-term high-temperature and high-humidity environment. The oil collecting part 71 precisely receives the grease dripping from the condensation plate 40 and the deep cavity, and the oil leakage hole 72 leads directly to the external oil cup, avoiding dripping and pollution.

[0042] Further, the lower part of the condensation plate 40 is located above the oil collecting part 71 and does not cross the front side of the installation frame. The end of the condensation plate 40 hangs directly above the oil collecting part 71, and the condensed oil drops directly drip into the groove, avoiding overflowing along the plate surface and polluting the stove top. The condensation plate 40 is retracted into the installation frame and is completely hidden from the user's perspective, maintaining the aesthetics of the kitchen space.

[0043] In this embodiment, the condensation plate 40 is provided with long strip-shaped air passing grooves 42. The additional air passing grooves 42 arranged on the condensation plate 40 achieve the effect of low wind resistance and high throughput. The air passing grooves 42 balance the condensation area and the ventilation requirements, avoid air flow blockage, and maintain the suction efficiency.

[0044] Specifically, the air passing slot 42 is arc-shaped, linear, or a combination of both.

[0045] The test of the oil separation degree is generally measured by an oil fume separator oil separation degree test device. Its main box body includes an upper balance chamber and a lower oil fume generation chamber separated by an intermediate plate. The appliance to be tested is installed on the top of the oil fume generation chamber, and its air outlet can vertically lead to the balance chamber through the sealed intermediate plate.

[0046] By weighing the weight difference between the oil fume separator and the filter before and after the test with an electronic balance, the oil separation degree is calculated in combination. The applicant compares the oil separation degree data of different types of double-layer assembled oil fume separators with front and rear frames 20 as follows: The first type is a flat oil fume separator, with an oil separation degree of 91% to 93%; the second type is a conventional deep-well oil fume separator, with an oil separation degree of 93% to 95%; the third type is a deep-well oil fume separator with a condensation plate 40, and the condensation plate 40 has no air passing slot 42, with an oil separation degree of 95% to 97%; the fourth type is a deep-well oil fume separator with a condensation plate 40, and the condensation plate 40 is provided with an air passing slot 42, with an oil separation degree of 96% to 98%.

[0047] In this embodiment, the front frame 10 is provided with a handle 11, and an avoidance notch 43 for avoiding the handle 11 is provided above the condensation plate 40. The avoidance notch 43 ensures that the handle 11 can be operated without obstruction when disassembling the separator, and prevents the condensation plate 40 from scratching the user's hand. Optimization of coexistence of functional components: A compatible design that realizes the rapid application of force by the handle 11 and the full coverage of the condensation plate 40 in a compact space.

[0048] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations and substitutions are all included within the scope defined by the claims of this application.
