Range hood

Abstract

The invention discloses a range hood which comprises a smoke collection cover, a smoke blocking plate and an air curtain device, wherein an air inlet is formed in the smoke collection cover; an air outlet is opened or closed selectively by the smoke blocking plate; and the air curtain device comprises an air blower and an air outlet device which jets out airflows sucked by the air blower. The range hood is characterized in that the air outlet device coats the smoke blocking plate exteriorly; and the air outlet device comprises a jet guide channel which is formed on one side, facing inside of the smoke collection cover, of the smoke blocking plate, and can jet airflows to the inner surface, facing inside of the smoke collection cover, of the smoke blocking plate. In comparison with the prior art, the range hood disclosed by the invention has the beneficial effects that through formation of uniform jet spraying gas on the inner surface of the smoke blocking plate, jet guide gas is formedby the jet spraying gas; and an air film is formed by both the gases, so oil smoke is isolated from the smoke blocking plate, oil stains on the lower surface of the smoke blocking plate are reduced and thus dripping of condensed oil on the smoke blocking plate can be avoided.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Chinese cooking will produce a lot of oily fumes. In order to keep the kitchen environment clean and the human body healthy, range hoods have become one of the essential equipment in modern home kitchens. Generally, range hoods include top suction type and side suction type. The side suction type range hood uses the principle of eddy current wind pressure to absorb most of the oil fume that is close to the stove in the form of an arc, which can reduce the adverse effects on human health. Influence, and the power source is close to the stove, basically will not reduce the suction effect of the power source, because of its good smoking effect, it is very popular among people. [0003] Common side-suction range hoods are equipped with a smoke baffle. When the range hood is in the cooking state, the smoke baffle is opened to expose the ai...

Problems solved by technology

[0004] However, during cooking, oil fume will adhere to and condense on the lower surface of the smoke baffle and the outer surface of the panel, and the condensed oil on the panel will flow along the panel to the oil cup, and will be collected by the oil cup at last, while the condensed oil on the lower surface of the smoke baffle will After gathering to a certain extent, it will drip onto the stove to pollute the stove, and even drip into the cooking pot to pollute the food being cooked
