る。[Detailed description of the invention] <Technical field> The present invention relates to a fan that is equipped with a fan motor and a separate oscillating motor, and uses the oscillating motor as a drive source to perform a neck oscillating operation of the fan head. It is designed to reduce the noise caused by
〈従来技術〉

ンモータとは別個に首振モータを頭部内に設け、
この首振モータをフアンモータの後方位置の取付
基板上に取着している扇風機がある。<Prior Art> Conventionally, as shown in, for example, Japanese Utility Model Application Laid-Open Publication No. 52-137148 and Japanese Utility Model Application Laid-Open Publication No. 53-20154, a swivel motor is provided in the head portion separately from a fan motor,
There is an electric fan in which this oscillating motor is mounted on a mounting board at a position behind the fan motor.
この種扇風機において、首振モータは複数の歯

合い音が発生するものである。又一方でこの首振
モータはビス止めによつて取付基板上に直接取着
されるので首振モータの振動が取付基板に伝達さ
れ、振動音が発生するものであつた。 In this type of electric fan, the oscillating motor is integrated with a reduction mechanism assembly consisting of a plurality of gear groups and serves as a driving source for the oscillation. The fitting noise is generated by the assembled parts. On the other hand, since this oscillating motor is directly mounted on the mounting board with screws, the vibrations of the oscillating motor are transmitted to the mounting board, producing vibration noise.
これら回転音、かみ合い音、振動音は、この首
振モータを含めフアンモータを囲繞しているモー
タカバー内に広がり共振されて外部に出て耳ざわ
りな騒音となつていた。 These rotating sounds, meshing sounds, and vibration sounds spread and resonate within the motor cover that surrounds the fan motor, including the oscillating motor, and are emitted to the outside, creating unpleasant noises.
この騒音を低減するために、取付基板上と首振
モータとの間に緩衝材を介装することも考えられ
るが、従来の首振モータは、実開昭53−20154号
公報に示すように、ビスを以つて取付基板上に取
着されていたので首振モータの取付け作業性自体
悪いものである上に、緩衝材の介装によつて更に
取付け作業性が悪くなる虞れがある。 In order to reduce this noise, it is possible to interpose a cushioning material between the mounting board and the oscillating motor, but the conventional oscillating motor is Since the oscillating motor is attached to the mounting board using screws, the workability of installing the oscillating motor is itself poor, and there is a risk that the installation workability will be further deteriorated by the interposition of the cushioning material.
又、一方でモータカバー内の首振モータの騒音
を低減するために、首振モータをモータカバー内
で更にケースで囲繞することも考えられるが、こ
のケースを単に設けてビス止めするのであれば、
作業性の低下は免れない。 On the other hand, in order to reduce the noise of the oscillating motor inside the motor cover, it is possible to further surround the oscillating motor with a case inside the motor cover, but if this case is simply provided and fixed with screws, ,
A decrease in work efficiency is inevitable.
そこで、ケースの固定構造として実開昭49−
84657号公報に記載されているような構造を採用
すればネジ止めに対する優位性はある。 Therefore, as a fixing structure for the case,
Adopting the structure described in Publication No. 84657 has an advantage over screw fixing.
しかし、単に当該係着構造を採用しても首振モ
ータの場合、うまくいかない。 However, simply adopting this locking structure will not work in the case of an oscillating motor.
何故なら、首振モータが首振用のクランクを回
転させるものであるため、その反作用によりモー
タが回転し易く、モータの出力を完全にクランク
に伝達できない上に、磨擦による部品の摩耗、破
損を生じる虞れがある。 This is because the oscillation motor rotates the oscillation crank, so the motor tends to rotate due to the reaction, and the output of the motor cannot be completely transmitted to the crank, and parts may be worn out or damaged due to friction. There is a possibility that this may occur.
これを防ぐために、ケースの首振モータに対す
る圧着力を強めれば、ケースの係着自体極めて困
難になり、結局ビス止め等の固着手段が必要とい
うことになつてしまう。 In order to prevent this, if the pressing force of the case to the oscillating motor is strengthened, the case itself becomes extremely difficult to engage, and as a result, fixing means such as screws are required.
〈目的〉
