Claims

[Scope of Claim for Utility Model Registration] (1) An injection port capable of injecting compressed air toward the inside of the diversion passage is provided in the circumferential direction of a diversion passage having a suction side and a discharge side, and the discharge side of this injection port is provided. is provided with a Coanda surface having a substantially arc-shaped cross section that continuously bulges out from the inner wall surface of the injection port into the guide passage and is smoothly curved toward the discharge side to form a blowing section. A compressed air supply unit that supplies compressed air to the injection port via a ventilation pipe is connected, and the jet from the injection port is deflected to the discharge side by the Coanda effect on the Coanda surface, and the jet flow is deflected from the suction side into the diversion passage. A Coanda type blower characterized by being configured to form a flow toward the discharge side. (2) In paragraph 1 of the claims for utility model registration,
A Coanda type blower characterized in that the ventilation pipe is provided with a heat exchanger capable of heating or cooling the compressed air flowing inside. (3) Scope of claims for utility model registration, paragraph 1 or 2
2. The Coanda blower according to item 1, wherein the blower section is made of a transparent material.
