Document Type and Number:
WIPO Patent Application WO/2016/068280
Kind Code:
A1
Abstract:
A blower device comprising: a motor unit having a center axis oriented in the vertical direction; an impeller connected to a rotating section of the motor unit and sending air from above same towards the radial outside direction; an impeller cover section having an inner surface that covers the outer circumference of the impeller and above the outer circumference edge section and having an air intake in the center thereof; a main body cover section coupled to the impeller cover section, covering the outer circumference of the motor unit, and forming a cylindrical space between same and a housing cylindrical section; and a plurality of guide blades arranged at even intervals in the circumferential direction in the cylindrical space and each extending in the radial direction between the inner surface of the main body cover section and the housing cylindrical section. Each of the plurality of guide blades has a guide blade upper section positioned on the upper side thereof and a guide blade lower section positioned further on the lower side than the guide blade upper section. The guide blade upper section inclines more than the guide blade lower section, relative to the axial direction. The lower ends of the guide blades are positioned further forward, in the rotation direction, of the impeller than the upper end of the guide blades. At least one guide blade lower end is positioned further on the upper side than the lower end of the housing cylindrical section.
