WIPO Patent Application WO/2017/126240
Kind Code:
A1
Abstract:
An after-air port having two types of after-air with the properties of linearity and spreading, wherein, in order to maintain the penetration force of after-air jets sharing the linearity, an inside primary after-air nozzle (501) for supplying inside primary after-air is provided at the center within an opening so as to jet a linear flow, and an outside primary after-air nozzle (502) for supplying outside primary after-air is provided on the outside of the inside primary after-air nozzle (510) so as to jet a linear flow. A secondary after-air nozzle (14) for supplying secondary after-air is provided on the outside of the outside primary after-air nozzle (502). One or more secondary after-air guide vanes (15) having an inclination angle to the central axis of the after-air port are provided so that the secondary after-air can be horizontally deflected and supplied to the outlet of the secondary after-air nozzle (14). An adjusting member (301) for the amount of primary after-air supplied in the inside primary after-air nozzle (501) and/or an adjusting member (302) for the amount of outside primary after-air supplied in the outside primary after-air nozzle (502) are provided.
