Baffle-rotary lampblack absorber capable of adjusting area of air suction port

Abstract

The invention relates to a baffle-rotary lampblack absorber capable of adjusting the area of an air suction port, which comprises a casing, a blower, an air inlet and an air outlet. The baffle-rotary lampblack absorber capable of adjusting the area of the air suction port is characterized in that the air inlet is provided with an adjustable device which comprises at least one wind shield and a rotating shaft, wherein the wind shield and the rotating shaft are movably connected, and the wind shield and the casing are movably connected by a connecting device. In the invention, as the adjustable device is arranged on the air inlet, a user can manually or automatically move the wind shield of the air inlet according to amount of lampblacks and needs; the structural design of a rotary baffle is adopted, so the size of the air inlet can be conveniently and rapidly adjusted, thereby not only saving the energy resource and being beneficial to environment protection, but also enhancing the air suction strength under the situation of not changing the power of the lampblack absorber; the size change of the air suction port of the movable baffle is even on the structural design, thereby the adjustment is convenient; and meanwhile, the invention has constant air suction central point, effectively improves the air suction ratio and achieves the sound air-suction effects of sucking in dense smoke in time and purifying room air during the air suction process.

Description

technical field [0001] The invention relates to a range hood, in particular to a baffle rotating type range hood with adjustable tuyere area. Background technique [0002] The range hood is a kind of kitchen utensil that is almost necessary in every household. It helps inhale the range hood and purifies the air in the kitchen. The size of the air inlet of the range hood in the prior art is a fixed structure, which means that the suction strength is also stable. In actual operation, when the oil fume is small, because the power of the range hood remains unchanged, the set suction strength is too large, which will inevitably waste energy. When the oil fume becomes larger, the air inlet with a fixed area Because only one suction strength can be achieved, in many cases it cannot meet the actual emission of oil fume, which will cause indoor pollution. Some people think of using a plate to cover part of the air inlet, by reducing the area of ​​the air inlet to enhance the streng...

In actual operation, when the oil fume is small, because the power of the range hood remains unchanged, the set suction strength is too large, which will inevitably waste energy. When the oil fume becomes larger, the air inlet with a fixed area Because only one suction strength can be achieved, the actual emission of oil fume cannot be satisfied in many cases, which will cause indoor pollution

Some people think of using a plate to cover part of the air inlet, by reducing the area of ​​the air inlet to enhance the strength of the air suction, and blocking the area of ​​the air inlet by this cover, but the change process is difficult to control and adjust
