Description
【００１１】
【課題を解決するための手段】
この発明に係る電動送風機は、モータ部と、このモータ部のフレームと、前記モータ部の軸に設けられ、前方の中央開口から吸引した空気を周縁から吐出する送風ファンと、この送風ファンの後方側に設けられ、前記フレームの後方から吸引した空気を周縁から吐出する冷却ファンと、この冷却ファンの上流側に設けられ、前記モータ部側と前記冷却ファン側とを仕切る仕切り部材とを備え、電動送風機内部を流れる空気流の経路が、前記送風ファンの回転により発生する空気流と、冷却ファンの回転により発生する空気流とに分けられていることを特徴とする。
また、この発明に係る電動送風機は、モータ部と、このモータ部のフレームと、前記モータ部の軸に設けられ、前方の中央開口から吸引した空気を周縁から吐出する送風ファンと、この送風ファンの後方側に設けられ、前記フレームの後方から吸引した空気を周縁から吐出する冷却ファンと、この冷却ファンの上流側に設けられ、前記モータ部側と前記冷却ファン側とを仕切る仕切り部材とを備え、前記送風ファンにより吸引された空気を排出する排気口と、冷却ファンにより吸引された空気を排出する通気口をそれぞれ設けたことを特徴とする。[0011]
[Means for Solving the Problems]
The motor-driven blower according to the present invention comprises a motor unit, a frame of the motor unit, a blower fan provided on a shaft of the motor unit and discharging air sucked from a front central opening from the periphery, and a rear of the blower fan. The cooling fan includes a cooling fan provided on the side and discharging air sucked from the rear of the frame from the peripheral edge, and a partition member provided on the upstream side of the cooling fan and partitioning the motor unit side and the cooling fan side. It is characterized in that a path of an air flow flowing inside the electric blower is divided into an air flow generated by the rotation of the blower fan and an air flow generated by the rotation of the cooling fan.
The motor-driven blower according to the present invention includes a motor unit, a frame of the motor unit, a blower fan provided on a shaft of the motor unit and discharging air sucked from a front central opening from the periphery, and the blower fan. A cooling fan which is provided on the rear side of the frame and which discharges air sucked from the rear of the frame from the peripheral edge, and a partition member which is provided on the upstream side of the cooling fan and which divides the motor unit side from the cooling fan side; The apparatus is characterized in that an exhaust port for discharging air sucked by the blower fan and an air vent for discharging air sucked by the cooling fan are provided.

また、前記送風ファンと前記冷却ファンがプレートを介して一体形成されているものである。
また、前記冷却ファンの近傍に位置する軸受は前記仕切り部材の通気口及び冷却ファンの吸引口に配置されているものである。[0012]
Moreover, the said ventilation fan and the said cooling fan are integrally formed via the plate.
Further, the bearing located in the vicinity of the cooling fan is disposed at the vent of the partition member and the suction port of the cooling fan.

【発明の効果】
以上のように、本発明によれば、冷却効率が向上し、温度上昇によるモータ部の劣化を防止でき、高効率で長寿命の電動送風機を得ることができる。[0025]
【Effect of the invention】
As described above, according to the present invention, the cooling efficiency is improved, the deterioration of the motor unit due to the temperature rise can be prevented, and the electric blower with high efficiency and long life can be obtained.
【００２６】
また、軸受は前記仕切り部材の通気口及び冷却ファンの吸引口に配置されているので、冷却ファンより吸引された空気は、モータ部、並びにモータ部の軸受を冷却できるので、軸受の温度上昇によるグリースの劣化を防止でき、長寿命の電動送風機を得ることができる。[0026]
In addition, since the bearings are disposed at the vent of the partition member and the suction port of the cooling fan, the air drawn from the cooling fan can cool the motor and the bearings of the motor, so the temperature rise of the bearings Deterioration of grease can be prevented, and a long-life electric blower can be obtained.
