The invention relates to an air supply mechanism for a range hood. The range hood comprises a shell and an inner cylinder for limiting an oil smoke channel; a smoke gathering cavity is formed between the shell and the inner cylinder; the air supply mechanism comprises a wind wheel which is arranged in the smoke gathering cavity and a driving mechanism; the wind wheel sleeves the outer wall of the inner cylinder through a bearing, can rotate around the inner cylinder and generates air flow in the smoke gathering cavity; the driving mechanism is connected with the wind wheel and is configured to drive the wind wheel to rotate; the wind wheel rotates relative to the oil smoke channel to form airflow flowing downwards, so that the air supply mechanism supplies air to the lower part of the smoke gathering cavity; and the air supply mechanism is arranged in the smoke gathering cavity, so that the occupation of the air supply mechanism on an external space in the radial direction can be reduced. The invention further discloses the range hood.
Description
technical field [0001] The present application relates to the technical field of oil fume treatment equipment, for example, it relates to an air supply mechanism for a range hood and the range hood. Background technique [0002] At present, with the improvement of the quality of life, people's requirements for the oil fume extraction ability of kitchen range hoods are constantly increasing. As the height of high-rise buildings increases, the resistance of the kitchen range hood and the high-altitude wind resistance continue to increase, which often manifests as insufficient air volume and wind pressure, resulting in problems such as poor suction and escape of smoke. Some range hoods are equipped with a smoke collection chamber outside the smoke collection chamber. By supplying air to the smoke collection chamber, the air outlet of the smoke collection chamber forms a smoke collection air curtain on the periphery of the smoke collection chamber, so as to The smoke inlet form...
