Title:
BLOWER DEVICE
Document Type and Number:
Japanese Patent JP2017219029
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a blower device in which air blowing efficiency hardly deteriorates even when the thickness is reduced.SOLUTION: Housings 21, 22, 23 include: an intake port arranged at an upper part of a blower part; and an air blowing port 201 arranged radially outside of the blower part. The blower part includes: a plurality of flat plates 410 arrayed via a gap in an axial direction; and a spacer 420 arranged between the flat plates. A rotary part of the motor part has a hub having a flat plate holding part for holding the plurality of flat plates. When the blower part rotates, by viscosity resistance of the surface of the flat plate and a centrifugal force, an airflow going radially outside generates between the flat plates. As the airflow generates between the flat plates, the airflow hardly leaks in the vertical direction, and air blowing efficiency can be improved. Also, by arranging the spacer between the flat plates, the gap in the axial direction can be adjusted to a desired interval. Thereby, desired air blowing performance can be acquired. Furthermore, by the plurality of flat plates being held by the flat plate holding part, the blower part can rotate stably, and air blowing efficiency can be improved even further.SELECTED DRAWING: Figure 4
