Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and specifically relates to a range hood. Background Art

[0002] When the top-suction flat-panel range hood is working, the suction area is located directly below the smoke collecting hood. For a double-head gas stove, oil fumes are generated on both sides when cooking food. In actual use, the phenomenon of oil fume escaping easily occurs, affecting the user experience. In order to improve the problem of oil fume escaping easily in the top-suction flat-panel range hood, the existing solutions are assembled with multiple parts, resulting in large resistance, significant reduction in the overall air volume of the machine. At the same time, due to too many parts, there are problems such as complex structure, high cost, and high failure rate.

[0003] Chinese Patent with application number CN201420453779.8 discloses an oil filter net for an inwardly concave inverted cone type range hood, including an oil filter net. The oil filter net is in the shape of an inwardly concave inverted cone cap, with a fixing ring at the bottom. The fixing ring is folded upward in a U shape, and the inside of the U-shaped fold is an oil guiding groove. An oil outlet hole is provided in the oil guiding groove. The middle of the U shape of the oil guiding groove is connected to the bottom of the upward inclined plane, and the upper part of the inclined plane is connected to the top surface, and the connection part is an arc. A plurality of partition strips are evenly arranged on the circumference of the inclined plane. An air inlet groove is formed between every two adjacent partition strips. The partition strip is provided with an inwardly concave shape as an oil guiding channel, and a plurality of upper partition strips are evenly arranged on the top surface. An upper air inlet groove is formed between every two adjacent upper partition strips.

[0004] Chinese Patent with application number CN201820164728.1 discloses an oil net structure of a range hood and a range hood. The oil net structure includes an oil net body that is high in the middle and low around. At least part of the edge of the oil net body is provided with an oil guiding part, and the oil guiding part includes an oil guiding surface, and the oil guiding surface slopes downward in the direction from the middle of the oil net body to the periphery. The oil guiding surface can drain the grease filtered by the oil net structure into the oil tank, preventing the grease from accumulating and adhering to the smoke collecting hood and the connecting plate.

[0005] Although the above-mentioned prior art proposes technical solutions regarding the oil net, to a certain extent, it realizes the improvement of the problem that the top-suction flat-panel range hood is prone to oil fume escape. The oil net of its technical solution is fixedly arranged and cannot be adjusted accordingly according to different amounts of oil fumes, which is not flexible enough, and can only determine the oil fume suction effect by the distance between the oil net and the stove during installation.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention
