Description

Air inlet panel and smoke collecting hood and range hood comprising same Technical Field The utility model relates to the technical field of fume collecting hoods, in particular to an air inlet panel, a fume collecting hood comprising the air inlet panel and a range hood comprising the air inlet panel. Background The range hood is one of the indispensable kitchen household appliances in modern families, and with the improvement of the life quality of people, consumers have raised higher and higher requirements on the range hood effect and low noise when the range hood works. The grid type air inlet is widely applied to the prior range hood, and has the advantages of simple structure, small air inlet resistance and strong practicability. The grille type air inlet is characterized in that openings are uniformly formed in the panel of the air inlet, so that the suction distribution capability of the air inlet is weak, the grille structure is strong in permeability, the shielding capability of the whole fan noise in the range hood to external radiation is weak, the grille type air inlet is free of a space for attaching sound absorption configuration, and the possibility of further improving the noise reduction capability of the air inlet structure is reduced. Disclosure of utility model The utility model aims to overcome the defects of weak suction force of an air inlet and outward radiation of noise in the prior art, and provides an air inlet panel, a smoke collecting hood comprising the air inlet panel and a range hood. The utility model solves the technical problems by the following technical scheme: an air inlet panel, the air inlet panel includes: the noise reduction part is arranged in the middle area of the air inlet panel, is flat and is perpendicular to the air inlet direction of the air inlet panel; The air inlet is arranged on the periphery side of the noise reduction part in a surrounding mode, and the air inlet is arranged close to the edge of the air inlet panel; The connecting piece, the connecting piece set up in the air intake, the one end of connecting piece with the lateral part of portion of making an uproar falls is connected, the other end of connecting piece with the inner wall of air intake is connected. In this scheme, through setting up the portion of making an uproar that falls, and set up the air intake in the periphery side ring of the portion of making an uproar that falls, change traditional air intake setting position, expanded the suction distribution range outward for the air intake can be to the oil smoke absorption effect corresponding promotion of air intake panel edge, and the noise when absorbing the oil smoke can be reduced in air intake position change. And the noise reduction part can absorb noise, so that the noise is prevented from radiating outwards from the air inlet panel to influence the use experience of a user.
