うものであった。BACKGROUND OF THE INVENTION In recent years, there has been a demand for more and more compact products such as air conditioners. Conventionally, this type of once-through type blower
The configuration was as shown in the figure. In FIG. 4, the impeller 11 has a side plate 16 provided with a blade boss 14 for connecting the shaft 13 of the electric motor 12 on one side and a blade set screw 16 for fixing the shaft 13 and the blade boss 14.
and a side plate 19 provided with a shaft 18 for inserting into a bearing 17 and pivotally supporting the impeller 11 on the other side.
発明が解決しようとする問題点
このような従来の構成では、上記貫流形送風機のシャフ
ト１８および軸受１７が羽根車の側板１９より突出して
いるため、シャフト１８と軸受１７とを設けるためのス
ペースが必要で、送風に直接寄与しない空間が多く小型
化をするうえで、問題となっていた。Problems to be Solved by the Invention In such a conventional configuration, since the shaft 18 and bearing 17 of the once-through type blower protrude from the side plate 19 of the impeller, there is not enough space for providing the shaft 18 and bearing 17. However, there are many spaces that do not directly contribute to air flow, which poses a problem when downsizing.
本発明はこのような問題点を解決するもので、貫流形送
風機を取シ付けた機器本体の外形寸法をコンパクト化す
ることを目的とするものである。The present invention is intended to solve these problems, and aims to make the outer dimensions of a device body to which a once-through type blower is mounted more compact.
問題点を解決するための手段
この問題点を解決するために本発明は、両端に側板を有
した羽根車と、前記側板の一方に接続して前記羽根車を
回転させる電動機と、前記他方の側板を軸支する軸受と
を有し、前記他方の側板に凹部を設け、この凹部に前記
軸受を設けたものである。Means for Solving the Problem In order to solve this problem, the present invention provides an impeller having side plates at both ends, an electric motor connected to one of the side plates to rotate the impeller, and an electric motor connected to one of the side plates to rotate the impeller, and an electric motor connected to one of the side plates to rotate the impeller. A recess is provided in the other side plate, and the bearing is provided in the recess.
作 用
この構成により、貫流形送風機を使用する機器において
、前記一方の側板の端面よシ、羽根車の内側へ凹形状と
することにより軸受を設けるために必要とされていたス
ペースを最小限にすることができ、機器本体の外形寸法
をコンパクト化することが可能となる。Function: With this configuration, in equipment using a once-through type blower, the space required for installing a bearing can be minimized by making the end face of the one side plate concave toward the inside of the impeller. This allows the external dimensions of the device body to be made more compact.
実施例
以下、本発明の一実施例を第１図および第２図にもとづ
き説明する。第１図、第２図において、貫流形送風機は
羽根車１を回転させる電動機２を設け、羽根車１の一側

他側にはシャフト８を有した略凹形の側板９を設け、こ
の側板９の凹部内にシャフト８を受ける軸受が設けられ
ている。EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. 1 and 2, the once-through type blower is equipped with an electric motor 2 that rotates an impeller 1, and one side of the impeller 1 has a blade boss 4 into which the shaft 3 of the electric motor 2 is inserted, and a blade set screw 6. A substantially concave side plate 9 having a shaft 8 is provided on the other side of the impeller 1, and a bearing for receiving the shaft 8 is provided in the recess of the side plate 9.
このような構成により、貫流形送風機の軸受７や羽根ボ
ス４が側方へ突出しないため、貫流形送風機を小形化す
ることができ、第３図に示すような枠体２１と吸込口２
２とエアーフィルター２３と熱交換器２４と貫流形送風
機２６と吹出口２６とから成る空気調和機に用いた場合
、空気調和機本体の長手方向に対する外形寸法をコンパ
クト化羽根車１内の風の流れをスムーズに保つことがで
き、性能を低下させることはない。With this configuration, the bearing 7 and the blade boss 4 of the once-through type blower do not protrude sideways, so the size of the once-through type blower can be reduced, and the frame body 21 and suction port 2 as shown in FIG.
When used in an air conditioner consisting of an air filter 23, a heat exchanger 24, a once-through blower 26, and an outlet 26, the external dimensions in the longitudinal direction of the air conditioner main body are compact. The flow can be kept smooth without degrading performance.
