【考案の詳細な説明】
本考案は送風機に関するもので、従来、使用電
源周波数別に送風性能が異なるため、吸気面積を
変える必要があり、電源周波数別に専用の固定ダ
ンパーで能力調整を行つていたが、部品種類が増
えると共に在庫管理上も問題があつた。[Detailed explanation of the invention] This invention relates to a blower. Conventionally, the air blowing performance differs depending on the power frequency used, so the intake area had to be changed, and the capacity was adjusted using a dedicated fixed damper depending on the power frequency. However, as the number of parts increased, there were problems with inventory management.
本考案は、これを１個のダンパーで兼用できる
ようにしたもので、これを図面に基づいて具体的
に説明する。 The present invention allows a single damper to serve both purposes, and this will be specifically explained based on the drawings.
１はケーシング、２はフアン、３はフアンモー
タ、４はベルマウス、５はケーシング１の吸気開
口部１２に取付けたダンパーで、帽状に形成して
ありその平面部６に吸気口７を、側面部８に吸気
口９を設けてあり、吸気口７と吸気口９の両開口
面積を50Hz使用時の開口面積に、吸気口９のみで
は60Hz使用時の開口面積に設定してある。１０は
フアン２の取付ボスで、吸気口７を閉塞できる寸
法に形成してあり、ダンパー５を平面部６がケー
シング１の外方になるように取付ければ吸気口７
は開放し、ダンパー５を逆に取付ければ吸気口７
に取付ボス１０が嵌入して吸気口７が閉塞される
ように構成されている。１１は吸気ガイドであ
る。 1 is a casing, 2 is a fan, 3 is a fan motor, 4 is a bell mouth, 5 is a damper attached to the intake opening 12 of the casing 1, which is formed in a cap shape, and has an intake port 7 in its flat part 6; An intake port 9 is provided on the side surface 8, and the opening area of both the intake port 7 and the intake port 9 is set to the opening area when using 50 Hz, and the opening area of the intake port 9 alone is set to the opening area when using 60 Hz. Reference numeral 10 denotes a mounting boss of the fan 2, which is formed in a size that can close the intake port 7. If the damper 5 is installed with the flat part 6 facing outside of the casing 1, the intake port 7 will be closed.
If the damper 5 is installed in the opposite direction, the intake port 7 is opened.
The mounting boss 10 is fitted into the air intake port 7 to close the intake port 7. 11 is an intake guide.
本考案は上記構成からなり、今、50Hzに適用さ
せるときは、ダンパー５を平面部６がケーシング
１の外方になるように取付ければ吸気口７，９か
ら吸気することになり、開口面積は50Hz使用時の
設定開口面積となる。又、60Hzに適用するとき
は、ダンパー５を逆に取付けて平面部６をケーシ
ング１の内方に向け、吸気口７を取付ボス１０に
嵌入すれば、吸気口７は閉塞状態となり、吸気口
９からのみ吸気して開口面積は60Hz使用時の設定
開口面積となる。尚、吸気口７に取付ボス１０を
嵌入せずに当接させて閉塞してもよく、要するに
ダンパー５を逆方向に取付ければ吸気口７が閉塞
状態となるようにしておけばよい。 The present invention has the above configuration, and when applied to 50Hz, if the damper 5 is installed so that the flat part 6 is on the outside of the casing 1, air will be taken in from the intake ports 7 and 9, and the opening area will be is the set aperture area when using 50Hz. In addition, when applying to 60Hz, if the damper 5 is installed in the opposite direction so that the flat part 6 faces inward of the casing 1, and the intake port 7 is fitted into the mounting boss 10, the intake port 7 will be in a closed state and the intake port will be closed. Air is taken only from 9, and the opening area is the set opening area when using 60Hz. Incidentally, the mounting boss 10 may be closed by being brought into contact with the intake port 7 without being inserted into the intake port 7. In other words, the intake port 7 may be closed by attaching the damper 5 in the opposite direction.
本考案は以上のように、１個のダンパーで取付
方向を逆にすることにより、50Hz、60Hzの両電源
周波数に兼用でき、夫々の周波数に適した開口面
積となつて能力調整が簡単にできると共に部品数
も少くすることができる。 As described above, this invention allows one damper to be used for both 50Hz and 60Hz power supply frequencies by reversing the mounting direction, and the capacity can be easily adjusted by creating an opening area suitable for each frequency. At the same time, the number of parts can also be reduced.
