Range hood

Abstract

The invention discloses a range hood. The range hood comprises a box body structure and a fan frame used for arranging a fan system, the box body structure comprises a lower box body, a first air inlet and a second air inlet which are arranged in a left-right spaced manner are formed in the lower box body, and a first cavity and a second cavity which are independent and serve as air inlet cavities are formed in the lower box body; the first cavity corresponds to the first air inlet, and the second cavity corresponds to the second air inlet; and the range hood further comprises a first filter and a second filter, the first filter corresponds to the first cavity, and the second filter corresponds to the second cavity. The first filter comprises a first filter screen, the second filter comprises a second filter screen, the left part, abutting against the bottom of the lower box body, of the first filter screen is a ventilation area, and the right part, abutting against the bottom of the lower box body, of the second filter screen is a ventilation area; and the first filter and the second filter can rotate around a rotating shaft extending in the front-back direction, and therefore the area of the ventilation area of the first filter screen and the area of the ventilation area of the second filter screen are adjusted.

Description
