Description

The present invention relates to an air cleaner that supplies purified air and ions into a room, and a method of using the air cleaner.

  In an air purifier with an ion generation function added, the air sucked in from the outside by a blower fan or the like flows through the ventilation path, and the purification filter provided in the ventilation path removes harmful substances contained in the air. In general, an ion generator is installed in the vicinity of an air outlet that blows air to the outside, and ions generated by the ion generator are blown out together with purified air (see Patent Document 1).

  In addition, it has two ventilation paths that allow air sucked from different inlets to blow out and blow out to the outside from different outlets. One of the ventilation paths purifies the air sucked by the purification filter, and the other ventilation path uses ions. In an air cleaner that adds ions generated by a generator, a configuration is known in which the outlets of two ventilation paths are juxtaposed in the lateral direction and the blowing direction is upward in a parallel state (see Patent Document 2).
