Title:
AIR BLOWING DEVICE
Document Type and Number:
Japanese Patent JP2018087495
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air blowing device having first and second centrifugal fans, and allowing for improvement in the temperature miscibility of the blown air of the second fan by causing the second fan to suck the blown air of the first fan.SOLUTION: The blown air of a first fan 14 flows into an air guide passage 161 as a swirl flow which turns in the same direction as that of the first fan 14. Then, the air guide passage 161 guides the flow-in swirl flow to a second fan 20 while maintaining a swirl direction of the swirl flow. As a result, the second fan 20 which rotates in a direction reverse to the first fan 14 sucks air which forms the swirl flow swirling in a direction reverse to the second fan 20 from a second fan suction port 181a. Therefore, the air is strongly swirled by the second fan 20 when the second fan 20 sucks the air compared with the case that the air sucked by the second fan 20 is, for example, not swirled. The temperature miscibility of the blown air of the second fan 20 can be thereby improved.SELECTED DRAWING: Figure 1
