Top-close draft type range hood

Abstract

The invention relates to a top-close draft type range hood, which comprises a case mounted on a wall body and an exhaust fume-collecting hood obliquely connected with the lower part of the case, the case is provided with a front end surface and a rear end surface, the exhaust fume-collecting hood is provided with an exhaust fume-collecting panel, which is provided with a fume-sucking inlet, the exhaust fume-collecting panel is curved inwards and extended out of the front end surface of the case from the bottom up along the bottom of the rear end surface of the case, the distance Alpha between the extended tail end of the curved exhaust fume-collecting panel and the front end surface of the case is about 170mm to 180mm, and the included angle Beta between the straight connecting broken line drawn between the initial and the tail ends of the curved exhaust fume-collecting panel and the rear end surface of the case is about 50 degrees to 60 degrees. The structure of the range hood is simple and reasonable, the range hood can thoroughly suck fume, and moreover, the head of an operator cannot be bumped during use.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a top-close type range hood with simple and reasonable structure and improved smoking effect. Background technique [0002] The traditional European-style T-shaped range hood uses the top suction method to extract the range hood, such as figure 1 As shown, from the perspective of the vertical direction, the smoking surface of the range hood can completely cover the entire cooking surface, and the oil fume can be completely sucked out. To ensure a wide enough smoking surface, the smoke collecting panel of the range hood is generally wider , the operator is likely to touch the head during the cooking process; in order to solve the situation that the operator is easy to touch the head, side suction or near suction range hoods have emerged as the times require, such as figure 2 As shown, the side suction range hood adopts the method that the range hood surface and the wall surface on whi...

[0002] The traditional European-style T-shaped range hood uses the top suction method to extract the range hood, such as figure 1 As shown, from the perspective of the vertical direction, the smoking surface of the range hood can completely cover the entire cooking surface, and the oil fume can be completely sucked out. To ensure a wide enough smoking surface, the smoke collecting panel of the range hood is generally wider , the operator is likely to touch the head during the cooking process; in order to solve the situation that the operator is easy to touch the head, side suction or near suction range hoods have emerged as the times require, such as figure 2 As shown, the side suction range hood adopts the method that the range hood surface and the wall surface on which the range hood hangs form an angle β of about 30°, absorbing the range hood from the side of the rising path, and the overall width of the range hood is reduced, so that It solves the problem that the operator is easy to touch the head, but because the oil fume will rise automatically under normal circumstances, it is easy to cause the oil fume to leak from the side of the rising path of the oil fume, resulting in incomplete smoking
