A top-suction, side-suction hybrid range hood

Abstract

The invention discloses a top suction and side suction mixed range hood comprising a vertical exhaust fume collecting hood, a horizontal exhaust fume collecting hood and a box body arranged above the horizontal exhaust fume collecting hood, wherein the horizontal exhaust fume collecting hood is arranged at the top of the vertical exhaust fume collecting hood; the top of the vertical exhaust fume collecting hood communicates with the inside of the box body; a side suction air inlet is formed in the front side of the bottom of the vertical exhaust fume collecting hood; and a top suction air inlet communicating with the inside of the box body is formed in the top of the horizontal exhaust fume collecting hood. The top suction and side suction mixed range hood is characterized in that a telescopic mechanism capable of sliding in the back and forth direction to close or open the top suction air inlet is arranged inside the horizontal exhaust fume collecting hood and below the top suction air inlet. The telescopic mechanism is arranged in the horizontal exhaust fume collecting hood and moves in a telescopic way according to the exhaust fume air volume, and all-dimensional air intake is realized by virtue of the side suction air inlet playing a main role and the top suction air inlet playing an assistant role, so that a better exhaust fume suction effect is achieved.

Description

technical field [0001] The invention relates to a range hood, in particular to a top suction and side suction hybrid type range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types. Top-suction range hoods use the principle of rising hot air to absorb and exhaust the naturally rising oil fumes generated during cooking. It is more and more widely used, but because its power source is far away from the stove, the suction effect of the power source is reduced, and the oil fume cannot be completely sucked; the side suction range hood uses the vortex wind pressure to keep most of the The oil fume that is closer to the stove is absorbed in an arc, which can reduce the adverse effects on human health, and the power source is closer to the stove, so the suction effect of the power source will not be reduced basically, but because the oil fume rise...

Problems solved by technology

[0005] Although the above-mentioned range hoods combine the advantages of top suction and side suction, since the centrifugal fan is placed vertically, the performance loss of the centrifugal fan is likely to be too large, and the effect of the range hood is still poor; The suction port of the suction is fixed at a certain position to work, and cannot be adjusted according to the actual situation of the oil fume, which either causes a waste of resources or cannot completely suck the oil fume
