Description
【考案の詳細な説明】 産業上の利用分野 本考案は、建築設備に用いられる低騒音タイプの送風機
に関するものである。TECHNICAL FIELD The present invention relates to a low noise type blower used for building equipment.
従来の技術 従来、この種の送風機は第３図および第４図に示すよう
にモータ１により回転駆動するファン２をファン吸込口
3aを有するケーシング３に収納し、このケーシング３を
その吸込口3aを上向きにした状態で両側に吸気口4aと吐
出口4bを有する筐体４内に設置して送風を行うものであ
った。2. Description of the Related Art Conventionally, in this type of blower, as shown in FIG. 3 and FIG.
It is housed in a casing 3 having 3a, and the casing 3 is installed in a casing 4 having an intake port 4a and a discharge port 4b on both sides with the suction port 3a facing upward to blow air.
考案が解決しようとする課題 このような従来の構成では、筐体４の吸気口4aから吸込
まれた空気の大部分はケーシング３に衝突し、スムーズ
に吸込口3aに流れないため、送風機効率を低下させると
いう課題があった。さらに、ファン２およびモータ１よ
り発生する騒音が直接筐体４の吸気口4aから放出されて
しまうという課題もあった。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional configuration, most of the air sucked from the air inlet 4a of the housing 4 collides with the casing 3 and does not flow smoothly to the air inlet 3a, so that the efficiency of the blower is improved. There was a problem of lowering it. Further, there is a problem that noise generated by the fan 2 and the motor 1 is directly emitted from the intake port 4a of the housing 4.
本考案はこのような課題を解決するもので、簡単な構成
で効率の良い低騒音の送風機を提供することを目的とす
るものである。The present invention solves such a problem, and an object thereof is to provide an efficient and low-noise blower with a simple configuration.
課題を解決するための手段 この課題を解決するために本考案は、筐体の吸気口内側
にファン吸込口に向って立上げたガイドベーンを取付け
た送風機の構成としたものである。Means for Solving the Problem In order to solve this problem, the present invention has a structure of a blower in which a guide vane that is erected toward a fan suction port is installed inside an air intake port of a housing.
作用 この構成により、筐体の吸気口から吸込まれた気体はガ
イドベーンに沿って流れ、スムーズにケーシングのファ
ン吸込口方向に流れてファン効率が向上するとととな
る。さらに、モータおよびファンから発生した騒音がガ
イドベーンによって反射され筐体の吸気口から外部に直
接騒音が放出されるのを防止するものである。Action With this configuration, the gas sucked from the intake port of the housing flows along the guide vanes and smoothly flows toward the fan intake port of the casing to improve the fan efficiency. Further, the noise generated from the motor and the fan is prevented from being reflected by the guide vanes and directly emitted from the intake port of the housing to the outside.
実施例 以下、本考案の一実施例を第１図および第２図にもとづ
き説明する。なお従来と同一の構成部分には同一符号を
付して説明を省略する。本考案の特徴的な構成は、筐体
４の吸気口4aの内側にファン吸込口3aに向って斜めに立
上げたガイドベーン５を取付けた点にある。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The same components as those of the related art are designated by the same reference numerals and the description thereof will be omitted. The characteristic structure of the present invention is that a guide vane 5 is installed inside the air intake port 4a of the housing 4 so as to be obliquely raised toward the fan suction port 3a.
上記構成においてモータ１から出る騒音およびファン２
で発生したケーシング吸込口3aから出る騒音、ケーシン
グ３から出る騒音Ａは、筐体の吸気口4aから外部にもれ

ドベーン５に沿ってファン吸込口3aに流れ、ファン効率
が向上することとなる。In the above configuration, the noise emitted from the motor 1 and the fan 2
The noise A generated from the casing suction port 3a and the noise A generated from the casing 3 try to leak to the outside from the air intake port 4a of the housing, but the guide vane 5 immediately before the air intake port 4a of the housing.
The noise A is prevented from being reflected and reflected outside. Further, the gas B sucked from the intake port 4a of the housing flows along the guide vanes 5 into the fan suction port 3a, and the fan efficiency is improved.
考案の効果 以上の実施例の説明からも明らかなように、本考案によ
ればガイドベーンを筐体の吸気口の内側に取付けること
により、吸込気体がスムーズに流れることによる効率の
向上と、吸気口からの騒音を低減できるという効果が得
られる。Effects of the Invention As is apparent from the above description of the embodiments, according to the present invention, by installing the guide vanes inside the intake port of the housing, the suction gas smoothly flows to improve the efficiency and the intake air is improved. The effect that the noise from the mouth can be reduced is obtained.
