An air blower including a casing having an intake port and a discharge port an air-blowing fan disposed inside the casing to take in air through the intake port and discharge air from the discharge port; and a filter filtering the air taken in through the intake port, wherein an insect trapping part trapping an insect is disposed in a ventilation path between the intake port and the filter.

Air blower

A disc-shaped filter unit including a filter main body having a water absorbability and a holder having a non water absorbability is disposed in a vertical orientation, with a part of a circumferential portion thereof immersed in water reserved in a water tank, and is rotated by a rotation drive mechanism in a circumferential direction. The filter unit has an absorptive region and a non-absorptive region arranged adjacent to each other in the circumferential direction. Therefore, in accordance with rotation of the filter unit in the circumferential direction, a state where the absorptive region is immersed and the filter main body of the filter unit absorbs water through a water-conduction hole and a state where the non-absorptive region is immersed and water absorption of the filter main body is prevented by a watertight section having a non water absorbability are continuously alternated.

Humidifier, filter unit and rotation drive structure

In order to efficiently kill airborne fungi in a room, an ion generator includes an ion generator, a temperature sensor for detecting a temperature, and a humidity sensor for detecting a humidity. The ion generator is controlled based on a temperature detection result detected by the temperature sensor and a humidity detection result detected by the humidity sensor. As ions are generated in accordance with the temperature and humidity, airborne fungi can efficiently be killed.

Ion generator and air conditioner

There are provided a sirocco fan () and a filter unit (). Filter unit () includes a deodorization filter (), a filter () for removing an organic matter containing an aldehyde group, and an antibacterial/dust filter (). Deodorization filter () contains a carbon monoxide removing catalyst.
