Abstract

The invention relates to a range hood provided with an annular air duct. The range hood comprises an exhaust fume collecting hood, a control circuit and an air bellow internally provided with a fan, wherein the fan is electrically connected with the control circuit; the exhaust fume collecting hood comprises a frame adopting a closed loop shape or an opening loop shape; a hollow structure in the frame forms the annular air duct; the frame is connected with the air bellow; the annular air duct is communicated with the inside of the air bellow; exhaust fume suction ports are formed in the surface of the frame along the annular air duct and communicated with the inside of the air bellow through the annular air duct. According to the range hood, the exhaust fume collecting hood is changed into the frame-shaped structure, and a negative pressure cavity is changed into the annular air duct, so that the overall size of the exhaust fume collecting hood is greatly reduced; further, the exhaust fume ports are distributed along the annular air duct, so that a larger exhaust fume suction range can be defined, and the exhaust fume suction effect is not influenced under the condition that the size is reduced.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with an annular air duct. Background technique [0002] Existing range hoods are mainly divided into two types: side suction type and top suction type. ,higher cost. [0003] In addition, the position of the smoking port in the fume collection hood is fixed, so the design of the fume collection hood is to cover the stove as much as possible, so that even when there is no cooking or during the cooking process that produces a small amount of oil fume, the fume collection hood Always takes up more space. Contents of the invention [0004] The object of the present invention is to provide a circular air duct range hood with simple and reasonable structure, good smoking effect and small volume, so as to overcome the deficiencies in the prior art. [0005] The purpose of the present invention is achieved like this: [0006] A range hood with an annular air duct, comprising a smoke col...
