With the improvement of living standard and the improvement of urbanization rate of China, the range hood is one of necessities of kitchen appliances when people decorate houses. At present, the range hood is based on different user requirements, home decoration styles and the like, and the range hood models in the market are different, and are generally in the forms of a flat plate type, a side suction type and the like. The flat plate type range hood has the most direct advantages that the range hood can suck and exhaust naturally rising oil fume, smoke is gathered in a deep cavity, meanwhile, the range hood has a wider application market due to small occupied space, but the air inlet area for sucking and exhausting the oil fume is far away from a cooking bench, when the oil fume amount is large, the smoke leakage phenomenon can occur, and users complain about the large amount; the side suction machine has the advantages that the air inlet for smoking is close to the surface of the stove, and the smoking effect is better than that of a flat plate. But a small amount of escaping oil smoke can not be captured because the oil smoke rises quickly. Therefore, seven-shaped range hoods appear in the market, and the seven-shaped range hood structure is another form generated by integrating a flat plate and a side suction structure. The smoking function of the cooking range combines the advantages of a flat plate for absorbing naturally rising oil smoke and the advantages of a side-suction air inlet close to the cooking range.

However, the prior art has the following defects:

at present, the seven-shaped range hood in the market has no oil guide groove at the air inlet, and the air inlet of the range hood has no oil guide groove, so that a large amount of oil smoke generated by a user during cooking directly enters the range hood to cause excessive internal oil collection, and further cause the performance of the whole range hood to be poor; in other schemes, or a regular oil screen is added, the range hood adopting the oil screen has a certain filtering effect on oil smoke, but cannot guide the flow, so that airflow disorder at the air inlet is caused, and the smoking effect is poor.

In view of this, the present invention is provided.
