Air blower

An air blower comprising:

• a panel (3);
• a frame member (5) that is arranged to surround the panel (3) and has four blowout ports (13a, 13b, 13c, 13d) of air formed therein;
• and
• a fan (11a, 11b, 11c, 11d) that sends air to the four blowout ports (13a, 13b, 13c, 13d), respectively,
• the four blowout ports (13a, 13b, 13c, 13d) of the frame member (5) including a first blowout port (13a), a second blowout port (13b), a third blowout port (13c), and a fourth blowout port (13d),
• the first blowout port (13a) being arranged across the panel (3) from the second blowout port (13b),
• the third blowout port (13c) being arranged across the panel (3) from the fourth blowout port (13d),
• the four blowout ports (13a, 13b, 13c, 13d) causing airflows to be blown out in mutually different directions,
• the frame member (5) causing the airflows respectively blown out from the first blowout port (13a), the second blowout port (13b), the third blowout port (13c), and the fourth blowout port (13d) to collide with each other, thereby producing an air current going forward relative to the panel (3).
