摘要： PURPOSE:To improve pressure characteristics and to enable plate work of impeller by positioning the rear fringe side of the side face section of a hub on the outside in radius direction than the front fringe side and arranging the side face section of the hub vertically to the bottom face section of the hub. CONSTITUTION:The bottom face section 4b of a hub at the rear fringe of blade is star-shaped which is located on the outside in the radius direction than the bottom face 4a of the hub at the front fringe of blade. The flow which passes among blades becomes oblique flow which spreads in the radius direction. Since the oblique flow is obtained even if the side face section 5 of the hub is arranged almost vertically to the bottom face section 4 of the hub, it is possible to locate the bottom face section 4 of the hub on the blow-out side. Thus, it is possible to improve pressure characteristics of an air blower, and plate work of an impeller becomes possible.

摘要： PURPOSE:To obtain a high performance thin impeller, by forming the negative and positive pressure surface sides of a blade in a circular arc shape and a three-dimensional curve shape, respectively, and by specifying the angles between the rotation direction of the blade and the blade surfaces on the fore and back edges of the blade, respectively. CONSTITUTION:Blades 4 are arranged around the outer periphery of a hub 3. Further, leading edges 4xa, 4xb are formed in a cross-section X-X which is obtained by cutting the blade 4 at a predetermined radius position. In this sectional shape, the negative and positive pressure sides 5, 6 are formed in a circular arc and a three-dimensional curve, respectively. That is, large inlet and outlet angle beta1P, beta2P of the positive pressure surface side 6 are held at predetermined angles which have been obtained before the impeller is thinned so as to ensure a sufficient projected area of the blade 4, and a smooth shape blade surface is obtained on the negative pressure surface side 5. With this arrangement, it is possible to obtain a high performance thin impeller.

摘要： PURPOSE:To prevent blast noise by providing a suction port in the suction side surface of a hub and a plurality of holes in the hub side of the negative pressure surface side of the blade and providing an auxiliary blade on the inside surface of the hub in association with these holes in an impeller having a plurality of blades fixed to the outer periphery of an approximately cylindrical hub. CONSTITUTION:The impeller 8 of an axial blower has a plurality of blades 2 fixed to the outer periphery of an approximately cylindrical hollow hub 3 which is provided with a suction port 4 on its suction side surface 3a while provided with a plurality of holes 5 formed in the hub side surface 3b on the negative pressure surface side 2e of the blade 2. Auxiliary blades 9 are disposed on the inner peripheral side wall surface 3c of the hub side surface 3b provided with the hole 5... to be formed in a row of blades of a multiblade blower. Thus, at the rotation of the impeller 8, air is sucked from the suction port 4 into the hub 3 and discharged forcibly from a plurality of the holes 5 toward the negative surface side 2e of the blade 2 by the centrifugal blast action of the auxiliary blade 9 to prevent the air flow from exfoliation on the negative surface side 2e and restrain the increase of blast noise along with the turulence of flow caused by the exfoliation.

摘要： PURPOSE:To prevent damage to a field coil by positioning the field coil in a closed recess portion formed in a casing, and fixing a substrate to the casing, so as to make a permanent magnet and the field coil opposed to each other via the substrate. CONSTITUTION:A closed recess portion 23 is formed in the inside surface of a casing a which is opposed to a permanent magnet 12. And a plurality of field coils 18 are placed in the closed recess portion 23 and a substrate 24 is fixed to the casing a. And the field coil 18 is enclosed in the closed recess portion 23 of the closed recess portion 23. Then the field coil 18 of the stator 20 and the permanent magnet 12 of a rotor 25 are opposed to each other via the substrate 24. Consequently, since foreign matters can be prevented from contaminating the field coil 18, damage to the field coil 18 can be prevented.

摘要： PURPOSE:To deviate an exfoliating point on the rear side of a blade toward the rear edge to lessen the exfoliating region by locating the maximum warping position of a warping curve interconnecting the front and rear edges of blade toward the rear edge from the center between the front and rear edges. CONSTITUTION:A plurality of blades 12 are disposed on the outer peripheral surface of a hab 1 configured into a generally circular truncated cone. The section of blade 12 is configured such that a position (b) of the warping center line 17 of blade having the maximum height from a straight line interconnecting the front and rear edges 13, 14 is deviated from the central portion 15 toward the rear edge side. Since the maximum warping position is deviated thus toward the rear edge, the exfoliating point of flow on the rear side is deviated toward the rear edge to reduce a turbulence region 16 on the blade surface.

摘要： PURPOSE:To enable the impeller in the title to improve blowing efficiency and to lower noise by keeping the sum of the areas of outside surfaces of blades below the surface area of outside peripheral side surface of the impeller, and especially specifying the number of blades. CONSTITUTION:When a field coil is energized, a permanent magnet 2 formed integrally with a main plate 1 rotates to run an impeller (b), a flow from an air inlet 11 to a discharge opening 12 is produced, and the impeller operates as a blower. At this time, since the impeller (b) acts as a rotor of a motor (c), and the motor (c) is housed in a casing (a), the whole blower can be miniaturized. Further, by keeping the sum of the surface areas of the outside surfaces of blades 5 below the surface area of the outside peripheral side surface of the impeller (b), and by providing many blades of short circular arc length, an effective flow is formed on the surface on the blades 5, and thus the volume of work per blade 5 can be reduced. The pressure fluctuation on the blade 5 end can therefore be reduced, and the generation of noise can be restricted.

摘要： PURPOSE:To aim at improvement in blowing capacity by setting the number of blades of a multiblade blower down to more than 45 pieces, and making the sum total of areas of a blade outer surface smaller than that of the impeller peripheral side. CONSTITUTION:In a casing 14, there is provided with an impeller installing a blade 13 between a main plate 11 and a subplate 12. The number of blades of this impeller is more than 45 pieces, and a diameter ratio D1/D2 is set to D1/D2=0.9 or so, while the sum total of areas of a blade outer surface is made smaller than that of the impeller peripheral side. With this constitution, in spite of plenty of blade numbers, a blade passage is in no case narrowed so extremely, and a frictional loss is made smaller, thus blowing capacity is improvable.

The impeller (b) is made smaller in the sum total of outer surfaces of a circular blade 5 than a surface area of the peripheral side of the impeller (b), and the number of blades is set down to more than 45 pieces. With this constitution, blowing capacity is improved and, what is more, the promotion of low noise is contrivable.
