Description

Technical Field

[0001] The present invention belongs to the technical field of range hoods, and particularly relates to a range hood with an automatically flipping and opening / closing filter net. Background Art

[0002] A range hood is a kitchen appliance for purifying the kitchen environment. For a range hood, the smoking effect is its most important core function. For the smoking effect, the setting method, shape, and position of the filter net directly determine the smoking effect of the range hood. Nowadays, there are many types of range hoods, such as top-mounted range hoods. In this top-mounted range hood, the filter net is basically set in the form of a downward-convex cone, and the oil cup for containing waste oil and grease is set directly below the conical filter net. Therefore, this downward-convex conical filter net is not only not beautiful but also prone to the situation where oil and grease drip into the pot, and this setting method has a risk of contaminating food. For the above-mentioned top-mounted range hood, in order to solve the problem of oil and grease dripping into the pot, in the prior art, mostly an inverted conical filter net or a flat filter net is used for setting, and the oil cup is set at the rear below the depth side of the range hood. Although this setting method of the filter net can solve the problem of oil and grease dripping into the pot, because the oil and grease need to flow backward, the smoke collecting cavity and the box body surface are set to be inclined backward, thereby reducing the area of the negative pressure region of the smoke collecting cavity. Therefore, there are disadvantages such as poor smoke gathering effect, poor smoking effect, and high noise. Summary of the Invention
