Extractor hood

Abstract

The invention discloses an extractor hood. The extractor hood comprises an exhaust fume collecting hood, an exhaust fume collecting cavity concaved upwards is formed in the exhaust fume collecting hood, and a main air inlet is arranged on the rear side of the top of the exhaust fume collecting hood. The extractor hood further comprises an exhaust fume barrier and an air inlet body, the rear end ofthe exhaust fume barrier is rotationally connected with the top of the exhaust fume collecting hood, the overall exhaust fume barrier is located on the front side of the main air inlet, the rear endof the air inlet body is rotationally connected with the rear portion of the exhaust fume collecting hood, and the exhaust fume barrier is supported above the air inlet body. A first air inlet, a second air inlet, a first air outlet and a second air outlet are formed on the air inlet body. The air inlet body has a first position located in the exhaust fume collecting cavity and a second position rotated out of the exhaust fume collecting cavity. When the air inlet body is at the first station, the first air inlet is located in the exhaust fume collecting cavity, the second air inlet faces an exhaust fume source, and the second air outlet is located below the main air inlet and is opposite to the main air inlet. When the air inlet body is located at the second position, the first air inletfaces the exhaust fume source, the first air inlet is located below the main air inlet and is opposite to the main air inlet, and the second air outlet is closed by the exhaust fume barrier.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types. Top-suction range hoods use the principle of rising hot air to absorb and exhaust the naturally rising oil fumes generated during cooking. It is more and more widely used, but because its power source is far away from the stove, the suction effect of the power source is reduced, and the oil fume cannot be completely sucked; the side suction range hood uses the principle of eddy current wind pressure to absorb most The oil fume that is closer to the stove is absorbed in an arc, which can reduce the adverse effects on human health, and the power source is closer to the stove, so the suction effect of the power source will not be reduced basically, but because the oil fume rises faster...

AI Technical Summary

Problems solved by technology

But in actual use, this kind of range hood simply superimposes the top suction type and the side suction type, and only has one working mode, that is, the top suction type + side suction type working mode, which leads to , without the advantages of the top-suction range hood, it is impossible to avoid the influence of the side shell on special cooking conditions (such as cooking utensils are higher steamers, etc.)
