<p>The air conditioning device discharges ions into air inflowing through an inflow port and outflows the air from the outflow port. The air conditioning device includes an air passage branched into a first passage connected to a peripheral region including a part of a space close to an inner surface of the outflow port and a second passage connected to a central region including a center of the outflow port. The first passage is narrowed continuously from the upstream to the downstream of the air flow, so that the air passing through the first passage is accelerated to outflow at a higher speed than the air passing through the second passage. The ions contained in the air outflowing while passing through the second passage are blocked from charged things around the outflow port by the high-speed air outflowing while passing through the first passage.</p> |
