Background
At present, the oil nets used by the existing range hoods are mainly conical oil nets and flat oil nets. The conical oil screen has large inclination angle, smooth oil guiding and simple manufacturing process, thereby being approved by most manufacturers. However, because of the use of the conical oil screen, the structure of the range hood is limited, the exposed part of the oil screen not only affects the sight, but also the negative pressure area of the range hood is only distributed in a small area near the conical oil screen. Because the air inlet of the conical oil screen is far away from the air cabinet of the range hood, the suction force is reduced. The range hood using the oil screen can not completely collect the oil smoke generated by stir-frying during cooking, and the oil smoke is easy to drift.
The flat oil screen can effectively increase the negative pressure area of the range hood and can be hidden in the deep-drawn smoke collecting cavity, so that the range hood using the flat oil screen can not only uniformly disperse the oil smoke around the smoke collecting cavity and suck the oil smoke into the range hood, but also has a simple and elegant appearance. Therefore, the range hood is more and more popular with consumers, but due to the limitation of the deep-drawn smoke collection cavity process, the inclination angle of the flat oil net of the range hood cannot be too large, the inclination angle of the flat oil net can have an important influence on the smoke and oil guiding effect of the range hood, the flat oil net can disperse oil smoke, and the oil absorption and smoke exhaust efficiency can be reduced.
