The grill assembly comprises a grill body, and a plurality of blades formed at a predetermined separation providing a passage along an outer circumference of the grill body. The passage is at an acute angle with the flow direction of the whirling air current, and each blade includes a protrusion member protruding outwardly from the outer circumference of the grill body.
