  The present invention relates to an air conditioner including an ion generator that discharges ions into the air by discharge and a blower fan.

  In recent years, air conditioners equipped with an ion generator for discharging ions into the air by discharge and a blower fan have been widely used, and related arts are disclosed in Patent Documents 1 and 2.

  The ion generator described in Patent Document 1 is installed on, for example, a floor surface, and discharges ions into the room together with air from an air outlet provided on the upper surface of the main body case using an ion generator and a blower. As a result, ions can be distributed throughout the room.

  The portable air blower described in Patent Document 2 is installed, for example, on a table. Like Patent Document 1, an ion generator and a blower fan are used to collect ions together with air from an air outlet provided on the upper surface of the housing, which is the main body. Released. Since this portable blower can change the angle of the lid, which is a support, with respect to the housing, the blower outlet can be directed obliquely upward when it is installed on a table. Thereby, it is possible to emit ions to a limited region, for example, a region where a person exists.

Alternatively, other distances may be set.
