Title:
BLOWOFF NOZZLE
Document Type and Number:
Japanese Patent JP3585712
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively reduce noises by shortening drying time by forming a nozzle so as to blow air on hands immediately when the hands are inserted without increasing wind velocity more than needed and to effectively reduce noises by shortening drying time by increasing air quantity without accelerating wind velocity more than needed.
SOLUTION: Concerning the shape of air blowing port 9, at the top end of blowoff port 5, its shape watched from the front is gradually projected toward the outside and by blowing high-speed wind, drying time can be shortened. Since high-speed air accelerated rather than 90 m/s is not required by shortening drying time by blowing high-speed wind on hands uniformly, noises can be remarkably reduced with the deceleration of wind velocity, the number of rotations of high-pressure centrifugal air blower 8 can be reduced and power consumption can be reduced.
