Claims

[Scope of utility model registration request]

A vortex chamber is formed between an impeller in which a large number of blades are provided radially within an annular recess with a semicircular cross section, and a casing having four annular parts with a semicircular cross section at positions corresponding to the four parts,
In a vortex blower in which a suction port and a discharge port are attached to the casing and a partition weir is provided between the suction port and the discharge port, the partition weir in the recess of the casing is attached to a side surface that is inclined with respect to the blade. 1. A vortex blower, characterized in that a gap is formed between the inner and outer annular edges of the impeller and the end of the partition weir.
