Abstract

PURPOSE: To obtain a high static pressure of the blower with a less electric power, by deciding an outlet angle of the fan blade and an angle between an outlet end and inlet end of the fan blade respectively to be in a specific angle in the impeller where a proportion of an outer circumferential diameter to an inner circumferential diameter of the fan blade is made to a specific value.
CONSTITUTION: An impeller 9 comprises six sheets of blades 52 attached to a fan plate 50. A folded part 52' of the blade 52 to the fan plate 50 side and a folded part 52" to a blade 52 turnover-preventing reinforcement ring 51 side are fixed respectively by welding. The proportion of an inner circumferential diameter (d) to an outer circumferential diameter of the blade 52 is decided to 0.6W0.7, an oulet angle β1 of the blade 52 to 10°W30° and an opening angle between outer and inner circumferential ends of the blade 52 to 20°W60°. A shape of the impeller 9 determined by the above can obtain a high static pressure with a less electric power.
