An air blowing device and an air blowing system reduces a region where a person cannot be recognized in a space provided with the air blower, and achieves control of the air blower in view of a person in a larger range in the space. The air blower includes: a first sensor configured to detect a position of a human in a first human detection range; a receiver configured to receive a detection result of a second sensor transmitted from a transmitter of a sensor-mounted device, the sensor-mounted device including the second sensor configured to detect a position of a human in a second human detection range; and a controller configured to perform air blowing control when the first sensor does not detect a human in the first human detection range and the second sensor detects a human in the second human detection range.

Air blower and air blowing system

An air purifying operation is performed with a consideration for an influence of a purifying material on a person, and user's comfort and efficiency of the air purifying operation are both achieved. An air purifier includes a casing, an inlet, outlets, blowers, a decontamination unit, air ducts, movable louvers, a horizontal rotation mechanism, an ozone generation mechanism, human detection means, a control unit, or the like. The control unit detects whether or not there is a person in a room by the human detection means. Then, the control unit controls at least one of parameters including an ozone generation amount, a wind direction, an amount, and a speed of blown-out air based on the human detection result. Thus, if there is a person in the room, for example, a human avoiding operation, a human area operation, or the like can be performed. If there is no person, an indoor air purifying operation for uniformly purifying air throughout the room can be performed.

Air purifier

An air purifier capable of reducing time required for purification of a room without giving a feeling of discomfort to a human in the room is provided. During operation of an air purifier, air drawn from an inletinto a casingis purified by a purification deviceand the air is blown to the outside from an outlet. If a user of the air purifierselects a particular operation mode in which the user designates an air volume, a control deviceperforms air volume maintaining control. In the air volume maintaining control, with a volume of air blown out from the outletby the air blowing devicemaintained constant, a speed of the air is varied by an air guiding devicebased on a status of pollutant detection. Alternatively, the speed of the air is varied by the air guiding deviceand the volume of the air is varied by the air blowing device. Consequently, a dust removal efficiency can be enhanced without giving a feeling of being blown by air to a human in a room, enabling reduction of time required for purification of the room while maintaining user comfort.
