本発明は消音箱付ファンにおける製品の薄形化並びに吐
出方向自在化構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a structure for reducing the thickness of a fan with a sound deadening box and for making the discharge direction flexible.
従来の技術は、三菱電機(株)のカタログ三菱換気扇、
空調換気扇ロスナイ総合カタログにあるように、消音箱
内のファンは横軸状態に配置された構造となっていた。The conventional technology is Mitsubishi Electric Corporation's catalog Mitsubishi ventilation fan,
As stated in the Lossnay General Catalog for Air Conditioning Ventilation Fans, the fan inside the sound deadening box was arranged on a horizontal axis.
上記従来技術は、ファンが横軸状態となっているため、
スパイラルケーシングの寸法により製品の高さ寸法が決
まってくる。本構造では,より淳形化を図るという点で
は考慮がされていなかった。In the above conventional technology, since the fan is in a horizontal axis state,
The height of the product is determined by the dimensions of the spiral casing. In this structure, no consideration was given to making it more compact.
また、ファンの吸込口が消音箱内で各側面に対し対称の
位置にないため、吸込,吐出口の位置によっては、ファ
ンの空力性能が大幅に変化するため、吐出方向の自在化
も困難であった。In addition, since the fan's suction port is not located symmetrically with respect to each side of the sound deadening box, the aerodynamic performance of the fan changes significantly depending on the position of the suction and discharge ports, making it difficult to control the discharge direction. there were.
本発明の目的は、天井裏に設置される際、より使い易い
ように、より薄形化を図り、さらに、ダクトの接続が直
線でも直角の曲がりでも対応できるようにすることにあ
る。It is an object of the present invention to make the device thinner so that it is easier to use when installed in the ceiling, and to be able to connect the duct either in a straight line or at a right angle.
上記の目的を達或するために、本発明は消音箱内のファ
ンを縦軸状態に配置し、消音箱の四側面すべてに吸込,
吐出口を設けて、選択できる構造とした。これにより、
ファン羽根車が大きくなっても、平面の縦横寸法が大き

る。また、羽根車の吸込口に対して、消音箱の吸込口の
位置が三方向共、同様な条件になり、吐出方向が三方向
自在として使用が可能となる。In order to achieve the above object, the present invention arranges the fan in the sound deadening box in a vertical axis state, and draws air into all four sides of the sound deadening box.
It has a structure with a discharge port that can be selected. This results in
Even if the fan impeller becomes larger, the horizontal and vertical dimensions of the plane will only increase. The law will be able to be suppressed as much as possible. In addition, the position of the suction port of the muffling box with respect to the suction port of the impeller is the same in all three directions, and the discharge direction can be freely used in three directions.
薄形化については、製品の高さ寸法に関係する要素とし

動機の軸方向寸法があるが、羽根幅寸法については、羽
根幅を小さく押えて羽根車直径を大きくすることにより
所定の空力性能が得られ、流賂寸法については,羽根車
吸込口を電動機側とすることにより、電動機軸方向寸法

込口への流路形状をほぼ同様とすることができ、吐出口
の自在化が可能となる。Regarding thinning, the factors related to the height dimension of the product include the impeller blade width dimension, the flow path dimension of the impeller suction port, and the axial dimension of the motor. By keeping the impeller small and increasing the impeller diameter, the specified aerodynamic performance can be obtained, and by placing the impeller suction port on the motor side, the dimensions in the axial direction of the motor can be shared. It becomes possible to make it thinner. In addition, regarding the flexibility of the discharge port, among the four sides of the sound deadening box,
The shape of the flow path to the impeller suction port can be made almost the same on three side surfaces except for one side that becomes the discharge port, and the discharge port can be made freely.

三通りの中がら選択できる効果がある。[Embodiment] An embodiment of the present invention will be described below with reference to FIG. An impeller 1 of a centrifugal fan, a spiral casing 2 enclosing the impeller 1, an electric motor 3 with the impeller 1 attached to its shaft end, a sound deadening box 4 containing all of these, and four sides of the sound deadening box 4. This is a fan with a sound deadening box, which consists of a suction companion flange 5 and a discharge companion flange 6 attached to the provided suction and discharge ports, and a cover plate 7 that blocks the unused suction port, and the electric motor 3 is arranged with the vertical axis facing upward. The suction port is connected to the motor 3 at the end of the shaft.
An impeller 1 facing the side is attached. By adopting such a structure, the product can be made thinner. Moreover, there is an effect that among the suction and discharge ports provided on the side surface of the sound deadening box 4, one can be selected from among three types depending on the installation location.
本発明によれば,製品の高さ寸法を小さくとることがで
きるので、天井裏等の設置場所に適した薄形化を図れる
。According to the present invention, since the height of the product can be reduced, the product can be made thinner, making it suitable for installation locations such as the ceiling.
