Air inlet device and range hood

Abstract

The invention provides an air inlet device and a range hood, and relates to the technical field of kitchen appliances. The air inlet device comprises a hood body, a power system, a first filter screenand a second filter screen, wherein the first filter screen and the second filter screen are arranged at the air inlet, and the power system is used for driving the first filter screen and the secondfilter screen to move relative to each other so that the first filter screen and the second filter screen can be in a first matching state, a second matching state or a third matching state; when thefirst filter screen and the second filter screen are in the first matching state, one side of the air inlet is in the air inlet state; when the first filter screen and the second filter screen are inthe second matching state, the other side of the air inlet is in the air inlet state; and when the first filter screen and the second filter screen are in the third matching state, both sides of theair inlet are in the air inlet states. According to the air inlet device and the range hood, the air inlet mode can be changed according to the matching state of the first filter screen and the secondfilter screen, so that the effective negative pressure at the air inlet is used to the maximum extent, and the air inlet effect is improved; and meanwhile, the air inlet device and the range hood aresimple in structure and easy to obtain.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an air intake device and a range hood. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. Usually installed above the kitchen stove, it can quickly take away the waste burned by the stove and the harmful oil fume generated during the cooking process, and discharge it outside, reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. [0003] Usually, the process of extracting oily fumes by range hoods is realized by exhaust fans. At the same time, a filter is usually arranged at the air outlet to filter the oily fumes discharged into the air and reduce pollution to the air environment. [0004] At present, the air intake area of ​​household range hoods usually adopts a filter screen structure, and the air intake area of ​​most range hoods on the market adopts a fi...
