Abstract
PURPOSE: To make easier the disassembly and assembly of fan as well as lower the cost without increasing the number of parts by forming a bellmouth projecting to the fan side in the portion facing the inside diameter of fan of the intake part.
CONSTITUTION: As the fan 8 rotates, entering gas flows in the direction of arrow A1; that is, the gas running against the inside surface of the casing 10 passes by the frontal surface of the fan 8 and then is sent back to the fan 8 by the bell-mouth B of the intake part 18, thus enhancing the efficiency of fan as in the case of the conventional technology. Also, the disassembly or assembly of the fan 8, when the intake part 18 is separated from the casing 10, can be easily performed because the casing 10 has the opening 9 of the caliber d2 larger than the outside diameter d1 of fan. Furthermore, the bell-mouth B is formed in the intake part 18, so that cost can be reduced without increasing the number of parts.
