Abstract

The invention provides a range hood, and relates to the technical field of range hood structures. The range hood is designed for solving the problems that in the prior art, smoke flows back and flowsback from an ejection channel, so that lampblack flows back and taints odor, and the experience of cooking personnel is influenced. The invention provides a range hood. The range hood comprises a mainmachine, an ejection mechanism and an anti-backflow mechanism; the main machine comprises an air outlet pipeline; the ejection mechanism comprises an ejection shell covering the air outlet pipeline,and an ejection channel is formed between the ejection shell and the air outlet pipeline; the anti-backflow mechanism comprises an anti-backflow valve plate and a valve port formed in the ejection channel; when flue gas in the ejection channel flows forwards, the anti-backflow valve plate can be separated from the valve port, and the ejection channel is in a conducting state; and when flue gas inthe ejection channel flows reversely, the anti-backflow valve plate can be buckled with the valve port, and the ejection channel is in a blocked state.

Description

technical field [0001] The invention relates to the technical field of range hood structures, in particular to a range hood. Background technique [0002] With the development of society and the progress of science and technology, people also enjoy the fun of cooking while enjoying delicious food. Range hoods have been widely used in kitchens as household electrical appliances. The range hood can absorb and collect the oil fume and discharge it out of the kitchen during the cooking process of people, so that people cook in a prescription without oil fume, and provide a good cooking environment for people. [0003] To judge the performance of the range hood, it is mainly necessary to refer to the absorption effect of the range hood on the range hood and the absorption efficiency of the range hood. In the prior art, there is a range hood with an ejection-assisted suction structure, which utilizes the principle of a Venturi tube to increase the air volume of the range hood to...
