Description

Technical Field

[0001] This utility model relates to the field of range hood technology, specifically a full-panel top-suction range hood. Background Technology

[0002] As an indispensable appliance in modern kitchens, the main function of a range hood is to remove cooking fumes, keeping the kitchen environment clean and the air fresh. Currently, there are many types of range hoods on the market, among which top-mounted range hoods are widely popular due to their advantages such as easy installation and not taking up space above the stove.

[0003] However, existing top-mounted range hoods, especially those of traditional design, generally have some technical shortcomings.

[0004] Firstly, in terms of aesthetics, existing top-mounted range hoods typically expose the smoke collection area or main air intake directly in front of the user's line of sight. With prolonged use, cooking fumes accumulate a large amount of grease on these exposed intakes, the inner walls of the hood, and surrounding areas. This grease not only affects the overall appearance of the range hood, making it look dirty and cluttered, which contradicts the minimalist and aesthetically pleasing design philosophy of modern kitchens, but also makes cleaning difficult, adding an extra cleaning burden for users. This design makes the range hood a less than aesthetically pleasing component of the kitchen; instead, its tendency to easily become soiled often makes it a visual "weak point."

[0005] Secondly, regarding smoke extraction efficiency, existing top-mounted range hoods often suffer from concentrated suction at a specific point near the intake, resulting in poor collection of diffused fumes. Traditional designs often have relatively small intake areas or fail to create a wide smoke-collecting zone, meaning that while the range hood has some suction power, this power is mainly concentrated in the central area near the intake. Existing intakes often struggle to effectively capture fumes that spread outwards during cooking, especially those generated around the cooktop or escaped due to rising hot air. This inevitably causes some fumes to spill into the kitchen air, reducing purification efficiency and impacting air quality and user experience. This concentrated smoke extraction method limits the overall smoke collection coverage and efficiency of the range hood, failing to achieve comprehensive and effective capture of fumes from the cooking area. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a more compact structure and more beautiful appearance. It can effectively solve the problems of poor aesthetics, easy accumulation of oil stains, and poor effect on the diffusion and collection of oil fumes in existing technologies while ensuring strong suction power. In order to provide a more beautiful, easier to clean and more comprehensive smoke extraction effect, a full-panel top-suction range hood.

[0007] The purpose of this utility model is achieved through the following means: a full-panel top-suction range hood, which includes a smoke collection hood and a fan cabinet on its top. The bottom of the smoke collection hood is recessed and has a smoke collection area. An air inlet is provided in the smoke collection area and is connected to a smoke extraction module provided in the fan cabinet. When the smoke extraction module is working, it draws in oil fumes from the smoke collection area through the air inlet. The smoke collection hood is inclined with the front higher than the back. A condenser plate is suspended below the smoke collection hood. The condenser plate is located in front of the smoke collection area and the entire smoke collection area is located behind the condenser plate. The outer contour dimension of the condenser plate is larger than the downward projected area of ​​the smoke collection area. The condenser plate and the lower end face of the smoke hood are spaced apart vertically, forming an outer ring air intake between the condenser plate and the smoke hood.

[0008] Furthermore, the condenser plate has a central air inlet hole in the middle, which penetrates the condenser plate and is connected to the smoke collection area.

[0009] Furthermore, an air guide plate is also installed on the back of the central air inlet. The air guide plate and the condenser plate are installed in a staggered manner, forming an inner ring air intake channel between the air guide plate and the condenser plate.

[0010] Furthermore, an air guide ring is provided extending from the periphery of the air guide plate towards the condenser plate.

[0011] Furthermore, the air guide ring extends towards the condenser plate and is provided with several support feet, through which the air guide plate is installed and fixed to the condenser plate.

[0012] Furthermore, the central air inlet and the air guide plate are arranged in a rectangular shape.

[0013] Furthermore, a support plate is fixedly installed at the rear of the smoke hood, and several oil leakage holes are opened on the support plate. Correspondingly, an oil collection groove is installed below the support plate.

[0014] Furthermore, the back of the condenser plate is provided with several hook seats, and correspondingly, several fixed seats are provided in the smoke collection area. The condenser plate is fixed to the bottom of the smoke collection hood by connecting the hook seats and the fixed seats.

[0015] Furthermore, the condenser plate is supported on the support plate behind it, and an air-proof area is provided on the condenser plate corresponding to the position of the oil leakage hole.

[0016] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0017] This invention features a suspended condenser plate installed below the smoke collection hood, cleverly forming an outer ring air intake channel between the condenser plate and the lower end face of the smoke collection hood through vertical spacing. This design allows the range hood to move beyond relying solely on the traditional air inlet within the smoke collection area for concentrated smoke extraction, instead incorporating a large, surrounding air intake channel. The outer ring air intake channel significantly expands the smoke extraction area of ​​the range hood, effectively increasing the coverage of smoke collection.

[0018] When the smoke extraction module is working, it not only draws in cooking fumes through the smoke collection area, but also draws in rising and spreading fumes over a wide and even range through the entire outer ring air intake. This wide-area smoke extraction mode significantly improves the efficiency of capturing cooking fumes around the stove and even the entire cooking area. Especially for those fumes that are easy to spread in all directions, it can achieve more comprehensive and effective smoke collection, thereby greatly improving the overall purification effect of the range hood. The condenser plate of this invention is positioned in front of the smoke collection area, with the entire smoke collection area located behind the condenser plate. Furthermore, the outer contour dimension of the condenser plate is larger than the downward projected area of ​​the smoke collection area. From the user's perspective, the condenser plate effectively shields the smoke collection area and main smoke inlets inside the range hood. This "full-panel" design concept gives the front panel of the range hood a simple and flat visual effect, greatly enhancing the overall aesthetics of the product.

[0019] Because the main smoke inlet is concealed by the condenser plate, grease and grime are not directly exposed to the user during daily use, effectively avoiding the problem of grease buildup at the smoke inlet of traditional range hoods that affects their appearance. The condenser plate itself, as a relatively flat surface, is also easier to wipe and clean daily, thus reducing the user's cleaning burden and extending the visually clean period of the range hood.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. A full-panel top-mounted range hood includes a smoke collection hood 1 and a fan housing 2 located on top of it. The bottom of the smoke collection hood 1 is recessed to form a smoke collection area 3. An air inlet 4 is provided in the smoke collection area 3, which is connected to a smoke extraction module 5 located in the fan housing 2. When the smoke extraction module 5 is working, it draws in cooking fumes from the smoke collection area 3 through the air inlet 4. The smoke collection hood 1 is inclined with a higher front and lower rear. A condenser plate 6 is suspended below the smoke collection hood 1. The condenser plate 6 is located in front of the smoke collection area 3, and the smoke collection area 3 is located behind the condenser plate 6. The outer contour dimension of the condenser plate 6 is larger than the downward projected area of ​​the smoke collection area 3. The condenser plate 6 and the lower end face of the smoke collection hood 1 are spaced vertically, forming an outer ring air intake duct 7 between the condenser plate 6 and the smoke collection hood 1.

[0028] In this embodiment: When the smoke extraction module 5 is working, it generates negative pressure within the smoke collection area 3. Because the condenser plate 6 and the lower end face of the smoke collection hood 1 are spaced vertically, a large outer ring air intake duct 7 is formed around the smoke collection area 3. Under the action of negative pressure, the fumes generated during cooking, especially those that diffuse and rise in all directions, are drawn into the range hood through this wide outer ring air intake duct 7. The inclined design of the smoke collection hood 1, with its front higher than its rear, helps guide the airflow of fumes upwards and may accelerate the flow of condensed oil droplets. The condenser plate 6 is suspended below the smoke collection hood 1 and positioned in front of the smoke collection area 3. Its outer contour dimension is larger than the downward projected area of ​​the smoke collection area 3. From an external perspective, the smoke collection area 3 is completely obscured by the condenser plate 6.

[0029] The outer ring air intake duct 7 significantly increases the effective smoke extraction area of ​​the range hood, expanding the traditional centralized smoke extraction to a wide-range, all-around smoke extraction. This allows the range hood to more effectively capture the smoke around the stove and the diffused smoke, significantly improving the smoke collection coverage and efficiency, and solving the shortcomings of existing technologies that suffer from concentrated suction and poor smoke collection of diffused smoke.

[0030] Meanwhile, the condenser plate 6 shields the smoke collection area 3, giving the range hood a simple and flat "full panel" appearance. This effectively avoids the problem of traditional smoke inlets being directly exposed and easily accumulating grease, which affects the aesthetics. It greatly enhances the overall visual effect of the product and its integration with modern kitchens.

[0031] In one embodiment: a central air inlet 8 is provided in the middle of the condenser plate 6, the central air inlet 8 penetrates the condenser plate 6, and is connected to the smoke collection area 3. The air inlet 8 directly penetrates the condenser plate 6 and communicates with the internal smoke collection area 3. Under the negative pressure generated by the smoke extraction module 5, in addition to the oil fumes being drawn in by the outer ring air intake duct 7, the dense oil fumes directly facing the center of the stove can also be directly and quickly drawn in through the central air inlet 8.

[0032] The addition of the central air inlet 8, together with the outer ring air inlet 7, forms a "dual-channel" air intake structure. This allows the range hood to maintain a wide range of smoke collection while also providing a powerful direct suction capability for the most concentrated smoke directly above the cooktop. This combined internal and external air intake mode further optimizes the efficiency of smoke capture, ensuring comprehensive and effective extraction of smoke from different areas.

[0033] In one embodiment, a guide vane 9 is also installed on the back of the central air inlet 8. The guide vane 9 and the condenser plate 6 are installed in a staggered manner, forming an inner ring air intake duct 10 around the guide vane 9 and the condenser plate 6. When the fumes are drawn in through the central air inlet 8, they will first encounter the guidance of the guide vane 9. The guide vane 9 cleverly guides the airflow, causing it to further converge through the inner ring air intake duct 10 and enter the smoke collection area 3. The design of the guide vane and the inner ring air intake duct 10 provides secondary guidance and organization for the airflow of fumes entering the central area, reducing airflow turbulence and swirling, ensuring that the fumes can be introduced into the smoke collection area 3 more smoothly and efficiently, avoiding the stagnation or overflow of fumes inside the range hood.

[0034] In one embodiment, an air guide ring 11 extends from the periphery of the air guide plate 9 toward the condenser plate 6. This air guide ring 11 is located outside the inner ring air intake duct 10, providing additional constraint and guidance for the airflow entering the inner ring air intake duct 10.

[0035] The air guide ring 11 can more effectively gather and guide the oil fumes entering the inner ring air intake duct 10, prevent the airflow from escaping, and make it flow more concentratedly to the smoke collection area 3, thereby further improving the efficiency and stability of oil fume collection.

[0036] In one embodiment: the air guide ring 11 extends toward the condenser plate 6 and is provided with a plurality of support feet 12, and the air guide plate 9 is installed and fixed to the condenser plate 6 through the support feet 12.

[0037] In one embodiment, the central air inlet 8 and the air guide plate 9 are arranged in a rectangular shape. Rectangular designs typically offer a simple and orderly visual effect, easily matching the overall square or rectangular design style of the range hood.

[0038] In one embodiment: a support plate 13 is fixedly installed behind the fume hood 1, and the support plate 13 has several oil drain holes 14. Correspondingly, an oil collection trough 15 is installed below the support plate 13. Some of the oil vapor in the fume hood will condense into oil droplets during the intake process or when it encounters a cold surface inside the machine. These oil droplets will flow along the inner wall of the fume hood 1 or the condensation plate 6, and eventually collect on the support plate 13. The support plate 13 has oil drain holes 14, through which the condensed oil droplets flow down and are collected by the oil collection trough 15 installed below the support plate 13. This ensures that the oil in the fume hood is effectively separated and guided into the oil collection trough, preventing oil stains from accumulating inside the machine or dripping onto the stove, and maintaining the cleanliness of the inside and outside of the range hood.

[0039] In one embodiment: the back of the condenser plate 6 is provided with a plurality of hook seats 16, and correspondingly, the smoke collection area 3 is provided with a plurality of corresponding fixing seats 17. The condenser plate 6 is connected and fixed to the bottom of the smoke collection hood 1 by the hook seats 16 and the fixing seats 17.

[0040] In this embodiment: To facilitate the installation and removal of the condenser plate 6, a hook seat 16 is designed on its back, while a matching fixing seat 17 is provided inside the smoke collection area 3. By connecting and fastening the hook seat 16 and the fixing seat 17, the condenser plate 6 can be stably and reliably fixed under the smoke collection hood 1.

[0041] The hook-and-loop connection makes the installation and removal of the condenser plate 6 simple and quick, requiring no additional tools, greatly facilitating daily cleaning and maintenance. The detachable design of the condenser plate 6 allows users to easily remove it for thorough cleaning of its back and the interior of the smoke collection area 3, effectively solving the problem of hard-to-clean areas inside the range hood.

[0042] The condenser plate 6 is supported on the support plate 13 at the rear, and the condenser plate 6 has an air-proof area 18 at the position corresponding to the oil leakage hole 14.

[0043] In this embodiment, the rear structure of the condenser plate 6 is cleverly integrated with the support plate 13, with its rear portion directly supported on the support plate 13, forming a stable support. To ensure that the oil droplets condensed on the condenser plate 6 can flow smoothly to the oil drain holes 14 on the support plate 13, the condenser plate 6 is specially provided with clearance zones 18 at the positions corresponding to the oil drain holes 14. These clearance zones 18 provide a smooth flow path for the oil droplets, preventing them from accumulating or overflowing due to obstruction. The design of the clearance zones 18 ensures that the oil droplets formed on the condenser plate 6 can flow unimpeded into the support plate 13 and eventually into the oil collection tank 15, further improving the efficiency and reliability of the oil collection system and preventing oil sludge retention.

[0044] In addition, the condenser plate 6 is supported on the support plate 13, which makes the bottom structure of the entire range hood more compact and stable, and makes effective use of space, integrating the functions of condensation, oil guiding and oil collection.

[0045] In summary, this utility model provides a full-panel top-mounted range hood, whose core working principle lies in achieving efficient, comprehensive, and aesthetically pleasing fume extraction and cleaning through a multi-air intake channel design and a condensate oil separation system.

[0046] When the user turns on the range hood, the smoke extraction module 5 inside the fan housing 2 starts working, generating a strong negative pressure inside the smoke collection hood 1, especially in the smoke collection area 3. This negative pressure is the power source for the entire range hood to extract and exhaust fumes.

[0047] Firstly, regarding the capture of diffuse cooking fumes, this invention cleverly incorporates a condenser plate 6 suspended below the fume hood 1. The condenser plate 6 and the lower surface of the fume hood 1 are spaced vertically, forming a wide outer ring air intake duct 7. When cooking fumes rise and diffuse during cooking, these diffused fumes are first attracted by the large negative pressure area of ​​the outer ring air intake duct 7 and then drawn into the range hood along it. The inclined design of the fume hood 1, with its higher front and lower rear, also helps guide the airflow of fumes upwards. This significantly improves the fume collection coverage and the efficiency of capturing diffused fumes, overcoming the shortcomings of concentrated suction and small collection range in existing technologies.

[0048] Secondly, to more effectively capture the dense fumes directly above the stove, a central air inlet 8 is provided in the middle of the condenser plate 6. This inlet penetrates the condenser plate 6 and connects to the smoke collection area 3. In this way, the range hood forms a "dual-channel" air intake mode combining the outer ring and the center. The dense fumes directly facing the center can be directly and quickly drawn in through the central air inlet 8, working in conjunction with the outer ring air intake duct 7 to ensure comprehensive and efficient capture of fumes throughout the entire cooking area.

[0049] To further optimize the airflow organization of the central air intake, a guide plate 9 is installed on the back of the central air intake 8. The guide plate 9 and the condenser plate 6 are installed in a staggered manner, forming an inner ring air intake duct 10 around it. A guide ring 11 extends from the periphery of the guide plate 9. When the fumes enter through the central air intake 8, the guide plate 9 and the guide ring 11 precisely guide the airflow through the inner ring air intake duct 10 into the smoke collection area 3, reducing airflow turbulence and ensuring that the fumes can be smoothly and efficiently drawn in. The guide plate 9 is firmly connected to the condenser plate 6 through the support feet 12 on its guide ring 11, ensuring the stability of the structure. All the fumes drawn in through the outer ring air intake duct 7, the central air intake hole 8, and the inner ring air intake duct 10 will eventually converge in the smoke collection area 3, and be drawn into the air handling unit 2 by the smoke extraction module 5 through the air inlet 4 in the smoke collection area 3 and then discharged.

[0050] During the fume extraction process, some of the oil vapor in the fumes condenses upon encountering the condenser plate 6 or other relatively cool surfaces of the machine body, forming oil droplets. These condensed oil droplets flow along the inner wall of the condenser plate 6 or the fume hood 1. To effectively collect these oil droplets, a support plate 13 is fixedly installed at the rear of the fume hood 1. The rear part of the condenser plate 6 is cleverly supported on the support plate 13, guiding the oil droplets to the support plate 13. The support plate 13 has several oil leakage holes 14, and the condenser plate 6 has clearance zones 18 at the corresponding positions of the oil leakage holes 14, ensuring that the oil droplets can pass smoothly through the clearance zones 18 and the oil leakage holes 14, and finally collect in the oil collection tank 15 installed below the support plate 13. Users only need to clean the oil collection tank 15 periodically.

[0051] In addition, for easy daily cleaning and maintenance, the back of the condenser plate 6 is provided with several hook seats 16, and the smoke collection area 3 is provided with several corresponding fixing seats 17. The condenser plate 6 can be easily installed and removed through the connection between the hook seats 16 and the fixing seats 17, which greatly facilitates users to perform deep cleaning of the inside of the range hood and the back of the condenser plate.

[0052] In summary, this utility model, through its "full-panel" appearance design, combined with multi-level, large-area air intake channels including outer ring, center, and inner ring, as well as efficient oil condensation collection and convenient disassembly and assembly structure, achieves a comprehensive improvement in the range hood's aesthetics, smoke coverage, smoke collection effect, and ease of cleaning, providing users with a superior kitchen experience. Therefore, it can be widely promoted and used.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
