According to the range hood, the lower air inlet plate is independently arranged at the lower end of the mounting shell, the inner concave air cavity is formed in the lower air inlet plate, and when the range hood is used, the inner concave air cavity generates negative pressure under the action of the fan to form a negative pressure cavity, so that the fan can conveniently suck oil smoke, and the distance between an air inlet and a kitchen range is reduced; by arranging the inward concave air inlet mesh enclosure, the inward concave air inlet mesh enclosure is convenient for generating negative pressure, so that oil smoke escaping from the bottom is conveniently sucked, and the phenomenon of smoke leakage is avoided; and by arranging the integral glass panel, the integral glass panel can integrally cover the top mounting plate, the upper supporting plate and the lower air inlet plate, so that the integral glass panel structure can be conveniently cleaned in the subsequent cleaning process.

Description

Technical Field

[0001] The utility model belongs to the technical field of range hoods, and particularly relates to an integral panel structure of a range hood. Background Art

[0002] According to the eating habits in our country, cooking mainly involves stir-frying, frying, and deep-frying. When stir-frying vigorously, a large amount of oil fume is instantaneously generated. In order to extract the oil fume better and faster, the current range hoods on the market mainly increase the air volume and air pressure to obtain greater suction force, so as to instantaneously extract the oil fume. However, whether it is a T-shaped range hood or a near-suction range hood, there is still a certain distance between the air inlet and the cooking stove, and actually it is impossible to completely capture all the oil fume. When stir-frying vigorously, a large amount of oil fume is instantaneously generated, and part of the oil fume will escape from the front side and the left and right sides. Therefore, it is necessary to further solve the above existing drawbacks. At the same time, since the panel of the traditional range hood usually adopts a structure of multiple pieces spliced together, it is more difficult to clean during the subsequent cleaning process. Summary of the Invention
