却する送風機の冷却装置に関する。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a cooling device for a blower such as an electric fan or a dryer, which cools a motor using airflow generated by rotation of a fan.
従来、この種送風機の冷却装置として実公昭58

Conventionally, as a cooling device for this type of blower,
- There is one shown in No. 12533. That is, a wind shield plate is provided between the outer circumferential surface of the motor and the inner circumferential surface of the cover body of the motor cover that covers and protects the motor, and partitions the inside of the motor cover into front and rear sections, thereby blocking part of the airflow caused by the rotation of the fan. is guided from the air inlet of the cover main body through the inside of the motor to the opening of the front cover of the motor cover, thereby preventing a rise in temperature inside the motor, particularly of the windings.
しかしながら、前記の場合、モータカバーの前
蓋とは別に遮風板を設けねばならず、しかも、こ

であるが、部品点数および組立工数がさらに増加
する不都合がある。 However, in the above case, it is necessary to provide a wind shield separately from the front lid of the motor cover, and this wind shield has a section between the outer peripheral surface of the motor and the inner peripheral surface of the cover body from the front lid. It is necessary to provide supporting legs to partition the windshield at a predetermined distance, and to provide an engaging protrusion to prevent the wind shield from rotating, which not only increases the number of man-hours during assembly work but also makes it difficult to process the parts. be. Furthermore, in order to enhance the cooling effect of the motor, it is necessary to provide a cooling plate as a fin for the motor, but this has the disadvantage of further increasing the number of parts and assembly man-hours.
また、従来においては、実公昭59−16557号に
示すように、電動機の密閉形金属製ハウジングの
先端に、外周部に多数の通気部を有する金属板を

る。 In addition, in the past, as shown in Utility Model Publication No. 59-16557, a metal plate with numerous ventilation holes on the outer periphery was fixed to the tip of the closed metal housing of the motor, and the motor and metal plate were opened. There is one that is wrapped in a shaped synthetic resin cover.
これによると、ハウジングの先端の金属板が電
動機のフインとして作用するが、フアンによる空
気流がハウジング内を通ることなく抜けていくた
め、電動機内部を直接冷却することができるず、
冷却効果が低い欠点がある。 According to this, the metal plate at the tip of the housing acts as a fan for the electric motor, but since the airflow from the fan passes through the housing without passing through it, the inside of the electric motor cannot be directly cooled.
The drawback is that the cooling effect is low.
〔考案の目的〕
