Description

Smoke collectors and range hoods

technical field

The invention relates to the technical field of kitchen appliances, in particular to a smoke collecting device and a range hood.

Background technique

During cooking, the cooking utensils produce oil fume. As the heated oil fume naturally rises, it is sucked away from the smoke inlet of the range hood.
