Problems solved by technology

Moreover, the use of public flues to discharge oily fumes in buildings will also increase the shared area of ​​the building, reduce the effective use area, and increase the construction cost.
[0008] The axial flow fan is a fan product that is widely used. The outstanding advantages are: large air volume, simple structure, and low cost; the outstanding disadvantages are: the direction of air intake and exhaust is the same.
The installation restrictive conditions of the axial flow fan are highlighted. For example, the axial flow fan cannot be installed vertically above the stove, because it cannot ac

Abstract

The invention provides an axial flow type oil smoke ventilator which comprises a curved tube axial-flow oil smoke blower fan, a frame and an externally connected exhaust duct, wherein the curved tube axial-flow oil smoke blower fan comprises a bent pipeline, a fan motor arranged in the bent pipeline and a fan body arranged on a fan motor shaft, the fan motor is fixed in the bent pipeline through a fan motor support, the curved tube axial-flow oil smoke blower fan is mounted on the frame, and an air inlet is vertical and adown. The invention has the following beneficial effects: a brand new middle and high-grade axial flow type oil smoke ventilator can be constructed according to the invention; the axial flow type oil smoke ventilator has all the advantages of an axial-flow blower fan, e.g., great draft induction capacity and a simple structure; an ideal exhausting rate can be obtained by using a small-power motor; ceiling installation can be realized; ascending hot air during cooking can be fully utilized; a substantial energy saving effect is obtained, and manufacturing cost is substantially reduced; and a novel technical product with strong competitiveness is presented on middle and high-grade oil smoke ventilator market, and product types of middle and high-grade oil smoke ventilators are enriched.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood in an axial flow suction and discharge mode. Background technique [0002] The range hood is an electrical appliance that purifies the kitchen environment. It can quickly discharge the oily fumes harmful to the human body generated during the combustion process and cooking process of the stove to the outside, so as to ensure the health of cooks and a good home environment. [0003] The range hood fan is the heart of the range hood and plays a decisive role in the performance of the range hood. [0004] The range hoods of the existing medium and high-end range hoods, no matter they are top-suction or side-suction, all belong to centrifugal fans, and the structure and manufacturing process of centrifugal fans are complicated, the price is high, and the exhaust air volume is smaller than that of the axial flow fans of the same power, which leads to The prices of existing medium and high...
