[0027] The utility model is further described in detail below with reference to the accompanying drawings. A simple top-suction range hood comprises a smoke collecting hood 1, the middle part of the smoke collecting hood 1 is recessed upward to form a smoke collecting area 2, a wind cabinet 3 is installed on the top of the smoke collecting hood 1, a smoking module 4 in the wind cabinet 3 is connected to the smoke collecting area 2, and when the smoking module 4 is working, negative pressure is generated in the smoke collecting area 2 to absorb the oil smoke;

[0028] The smoke collecting hood 1 is the main structure, and the smoke collecting hood is surrounded by a single-layer plate to form a space with an opening at the lower end, which is used to initially receive the oil smoke rising from the cooking area. Compared with the traditional structure, it has a simple design, helps to concentrate the oil smoke, improves the overall smoke extraction efficiency, and is easy to clean and maintain.

[0029] The area formed by the upward depression in the middle of the smoke collecting area 2 is specially used to collect oil smoke and enhance the concentration of oil smoke absorption. The depression design increases the gathering effect of oil smoke, thereby improving the oil smoke absorption capacity of the smoke collecting module.

[0030] The wind cabinet is installed on the top of the smoke hood, and the built-in smoke module is responsible for generating negative pressure, thereby sucking in the oil smoke in the smoke collection area. This configuration ensures strong suction from bottom to top, so that the oil smoke is quickly extracted, reducing the retention time and diffusion of oil smoke in the room.

[0031] Furthermore, the smoke collecting area 2 is covered with a smoke guide plate 5 , and a smoke inlet 6 is formed between the periphery of the smoke guide plate 5 and the outer contour of the smoke collecting area 2 . The oil smoke enters the smoke collecting area 2 through the smoke inlet 6 around the smoke guide plate 5 and is sucked out by the smoking module 4 .

[0032] The smoke guide plate covers the smoke collection area, and forms a hollow smoke inlet around the smoke collection area. When the rising smoke contacts the smoke guide plate, it is guided around it and guides the smoke into the smoke collection area efficiently. By optimizing the flow direction of the smoke, the smoke extraction efficiency is improved, and the smoke is prevented from escaping, the adsorption efficiency of the smoke is improved.

[0033] In one of the embodiments, an oil filter plate 7 is installed in the smoke collecting area 2 , and the oil filter plate 7 is connected to the back side of the smoke guide plate 5 , and the smoke guide plate 5 is suspended and installed in the smoke collecting area 2 .

[0034] In one embodiment, two oil filter plates 7 are provided and installed in the smoke collecting area 2 in a bilaterally symmetrical manner. The oil filter plate 7 is provided with a plurality of oil filter holes 71 penetrating the body thereof.

[0035] Among them, the oil filter plate 7 is installed inside the smoke collection area to filter out the grease in the oil smoke entering through the smoke guide plate. At the same time, it plays the role of connecting the smoke guide plate to the smoke collection area, filtering the grease through the oil filter hole, reducing the accumulation of grease inside the range hood, and extending the life of the equipment. And because the oil filter net is arranged at the rear of the smoke guide plate, it plays the role of hiding the oil filter net, avoiding the oil filter net being directly exposed to the outside and affecting the appearance. In addition, the oil filter net is also arranged on the back of the smoke guide plate, and the oil filtered out by the oil filter net can drip onto the back of the smoke guide plate, avoiding the oil directly dripping onto the countertop and affecting hygiene.

[0036] In one of the embodiments: the oil filter plate 7 is rectangular in shape, and its four sides have connecting plates 72 extending toward its side walls. After the oil filter plate 7 is installed vertically, its connecting plates 72 are respectively connected to the upper end, front end and rear end of the smoke collecting area 2, and the connecting plate 72 located below is connected to the smoke guide plate 5.

[0037] Among them, the setting of the connecting plate can increase the contact area between the connecting parts, thereby providing a stronger supporting force and avoiding undesirable phenomena such as shaking of the smoke guide plate after installation.

[0038] In one embodiment, the outer contour of the smoke collecting area 2 extends inwardly to form a lower guide plate 21, and the free end of the lower guide plate 21 is bent upward to form an upper guide plate 22. The smoke collecting area 2, the lower guide plate 21 and the upper guide plate 22 together form an oil collecting groove 23 opening upward.

[0039] The lower guide plate 21 and the upper guide plate 22 together form an oil collecting tank. The oil collecting tank is designed to collect filtered oil, condensed oil in the smoke guide plate and the smoke collecting hood, prevent grease from dripping directly downward, and keep the kitchen environment clean.

[0040] In one embodiment, the free end of the upper guide plate 22 is extended with a side guide plate 24 toward the oil collecting tank 23. The side guide plate 24 guides the oil smoke and oil stains, making the air intake smoother and the oil stains can drip into the oil collecting tank. At the same time, the side guide plate 24 also protects the edge, preventing the user from being cut during cleaning, and ensuring the safety of the user during use.

[0041] In one embodiment, the outer contour of the smoke guide plate 5 extends into the upward orthographic projection range of the oil collecting tank 23, and a lighting lamp 52 is installed on the smoke guide plate. After the outer contour extends into the oil collecting tank, the oil on the back of the smoke guide plate can drip into the oil collecting tank under the action of gravity, which is convenient for collecting the oil.

[0042] In one embodiment, the outer contour of the smoke guide plate 5 is obliquely extended upward with an upper extension plate 51. The setting of the upper extension plate 51 plays a role in guiding the oil smoke and also plays a role in protecting the edge of the smoke guide plate, preventing the user from being cut during cleaning, and also ensuring the safety of the user during use.

[0043] In one embodiment, the lower end surface of the smoke collecting hood 1 is arranged in an inclined shape with the front being higher and the rear being lower.

[0044] In one of the embodiments, the oil collecting groove 23 is arranged in a rectangular ring shape on the outer contour of the smoke collecting area 2, and an oil leakage hole is opened at the bottom of the oil collecting groove 23 at the rear end, and an oil cup groove is suspended and installed at the rear bottom of the smoke collecting area 2 corresponding to the position of the oil leakage hole to receive the grease dripping from the oil leakage hole.

[0045] The above-mentioned inclined setting makes the oil collecting tank located thereon also inclined with the front higher and the back lower, so that the grease in the Shudie oil collecting tank flows backward under the action of gravity, and finally drips into the oil cup tank through the oil leakage hole at the lowest point. The user can clean the oil stains by disassembling the oil cup tank.

[0046] In summary, through this design, the range hood of the present invention achieves efficient absorption and filtration of oil smoke, simplifies the structure and improves the appearance and convenience of use.

[0047] The combination of high efficiency and high suction ensures the maximum efficiency of smoke extraction, while the built-in oil filter plate and oil collection tank process and collect grease to keep the equipment and kitchen clean. These improvements make the range hood of the present invention have obvious competitive advantages in the market, meet the needs of modern families for efficient, economical and beautiful kitchen appliances, and can be widely promoted and used.

[0048] Obviously, the above embodiments are merely examples for clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the claims created by the present invention.
