The specific embodiment:
Fig. 1 is the profile of the electric blower of expression the present invention first form of implementation, and Fig. 2 is the perspective view of the electric blower of expression the present invention first form of implementation.In the drawings, label 1 is a motor, it comprises stator 2, high speed rotor rotated 3, motor bracket 4 and carriage 5 etc., and above-mentioned support 4 has steam vent 4a and is fixed with motor 1, and above-mentioned carriage 5 is fixed on the motor bracket 4 and has a plurality of steam vent 5a on the end face of motor bracket 4 one sides.Label 6 is a fan, and it is fixed in by nut 8 on the axle 7 of rotor 3 of motor 1, and can be with rotor 3 rotation.Label 9 is a guide vane, and it comprises the diffusion part 9a of the air-flow that adjustment sucks from said fans 6 and this air-flow steerable motor 1 returned guide 9b.Label 10 is a fan cover, and it covers above-mentioned fan 6 and be pressed into is fixed on the carriage 5.
In addition, the gross area of the steam vent 4a of the total area ratio motor bracket 4 of the steam vent 5a of carriage 5 slightly little (being equivalent to 70-80%).
In the electric blower of said structure, if CD-ROM drive motor 1, then rotor 3 rotates with the fan 6 that is installed on the axle 7, air-flow from fan 6 suctions, shown in the direction of arrow among the figure, inside by fan 6, adjust by the diffusion part 9a in the guide vane 9 then, be divided into two strands of air-flows at last, wherein the peripheral inwall of one air communication passing through fan lid 10 and carriage 5 turns to about 90 degree and discharges from the steam vent 5a of carriage 5, another strand air-flow then turns to 180 degree, and the guide 9b that returns by guide vane imports motor 1 inside, and its steam vent 4a from motor bracket 4 when motor 1 is cooled off discharges.At this moment, according to experimental result as can be known about half from the air-flow that fan 6 sucks the steam vent 5a from carriage 5 with smaller angle discharge.
Therefore, be that air-flow sucks, turns to then 180 situations of spending, also all be sent to the motor bracket side to compare from fan with existing embodiment, the pressure loss of the turning part of the above-mentioned form of implementation of the present invention is less, and blowing effect height.
In addition, because the gross area of the steam vent 5a in the carriage 5 is less than the gross area of the steam vent 4a in the motor bracket 4, so the exhaust resistance of the steam vent 4a in the motor bracket 4 is less, the air-flow that sucks from fan is easy to flow into the less motor bracket of exhaust resistance 4 sides, thereby can suppress the rising of motor temperature.
In addition, though it is less to flow into the air-flow of motor bracket 4, cooling effectiveness has certain reduction, and experimental result still remains in the temperature range of characteristic condition of motor.
In addition, discharge along the side of motor bracket 4 by making the air-flow of discharging from the steam vent 5a of carriage 5, and guide etc. is set, can stop the rising of motor temperature at the steam vent 5a place of carriage 5.
Fig. 3 is the plane of the electric blower of expression the present invention second form of implementation.In the drawings, label 5 is for having the carriage of steam vent 5a.Label 9b is for returning guide, and it can send into motor 1 inside by the air-flow that fan sucks, and this guide is located on the guide vane.The peripheral lateral margin 12 of being located at the steam vent 5a on the carriage 5 is basic identical with the perimeter sides end 11 of returning guide.
In the electric blower of said structure, cross the diffusion part 9a of guide vane 9 from the air communication of fan suction, the air-flow that is turned to by the peripheral inwall of fan cover 10 and carriage 5 can keep rotating part, and the air-flow of discharging from the steam vent 5a of carriage 5 can clash into the inwall that returns guide 9b of guide vane 9 like this.
Owing to the steering angle of the air-flow of discharging from steam vent 5a is less, so this air-flow is equivalent to about half of the air-flow that sucks by fan, compare by 180 ° of situations that turn to, also all are sent to the motor bracket side with the air-flow that sucks by fan, the pressure loss of the turning part of present embodiment can reduce half, and can obtain higher blowing efficient.
In addition, because it is basic identical with the perimeter sides end 11 of returning guide to be located at the peripheral lateral margin 12 of the steam vent 5a on the carriage 5, so and the air-flow of the inwall bump that returns guide 9b of guide vane 9 can stop the rising of motor temperature like this along inner edge 13 inflow motor brackets 4 one sides of returning guide 9b.
According to the present invention, electric blower comprises: the fan that drives rotation by motor, to send into guide vane in the motor by the air-flow that this fan sucks, fixing above-mentioned guide vane and the fan cover that will cover fan are fixed in the carriage on the outer rim, are fixed on this carriage, have steam vent that air-flow that guide vane is sent here discharges and a motor bracket that motor is fixed in inside; In this electric blower, on the end face of the motor bracket side of above-mentioned carriage, be provided with a plurality of steam vents, the air-flow of being sent into by the said fans steam vent from above-mentioned carriage and said motor support is respectively discharged, thereby can obtain such electric blower, wherein can be reduced by the omnidirectional pressure loss that causes that flows of air-flow when turning to by fan cover and bracket perimeter inwall that fan sucked, the efficient of drying in addition is higher.
In addition, owing to be located at the gross area of the gross area of the steam vent on the end face of motor bracket side of carriage less than the steam vent in the motor bracket, can discharge by the steam vent from the less carriage of steering angle about half in the air-flow that sucks by fan like this, the air-flow of above-mentioned suction simultaneously also can flow into the less motor bracket of exhaust resistance one side at an easy rate, consequently can form electric blower, also can suppress the rising of motor temperature in addition with higher blowing efficient.
In addition, electric blower comprises: the fan that drives rotation by motor, to send into the guide vane that having in the motor returned guide by the air-flow that this fan sucks, fixing above-mentioned guide vane and the fan cover that will cover fan are fixed in the carriage on the outer rim, are fixed on this carriage, have steam vent that air-flow that guide vane is sent here discharges and a motor bracket that motor is fixed in inside; In this electric blower, on the end face of the motor bracket side of above-mentioned carriage, be provided with a plurality of steam vents, the peripheral lateral margin of being located at the steam vent on the carriage is basic identical with the perimeter sides end of returning guide, the gas discharge of the steam vent from carriage and motor bracket respectively by the said fans suction, half steam vent from the carriage with less steering angle from the air-flow that fan sucks is discharged like this, second half flows into the motor bracket side along returning the guide inner edge, consequently can obtain having the electric blower of higher blowing efficient, also can suppress the rising of motor temperature simultaneously.
