PURPOSE:To maintain thorough uniformity in the temp. and flow rate of the hot air to be blown off by providing a mixing chamber in a nozzle and changing forcibly the flowing direction of the hot air just before the mixing chamber thereby mixing the hot air from the right and left prior to blow-off of the hot air and making the pressure uniform. CONSTITUTION:A nozzle for blowing off hot air has two chambers 16, 17 which extend in the longitudinal direction of the nozzle and are isolated from each other in a nozzle 12 to admit the hot air respectively into the two chambers 16, 17 from both sides in the longitudinal direction of the nozzle, then to eject the hot air from the blow-off port 27 of the nozzle 12. A mixing chamber 18 into which the respective hot air flowing in the two chambers 16, 17 are admitted and mixed is provided as a chamber independent from the two chambers in the midway of the flow passage for the hot air from the two chambers 16, 17 to the port 27. Walls 23, 24 as a means for changing forcibly the flowing direction of the hot air are further provided in the flow passage of the hot air just before the mixing chamber 18. |
