本発明は電動フアンモータとフアンシユラウド
とを備える送風機に関するもので、例えば自動車
走行用エンジンのラジエータフアンに用いて有効
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blower equipped with an electric fan motor and a fan shroud, and is effective for use in, for example, a radiator fan of an automobile engine.
この種の送風機では、モータ内部に侵入した水
を排水するためモータ下面に水抜き穴が設けられ
ている。しかしながら、この水抜き穴より逆に雨
水が侵入することがあるので、従来のものでは第
１図もしくは第２図に示すようなパイプ１００が
水抜き穴に取り付けられていた。ただ、このパイ
プ１００はフアンの通風面内に配設されるので、
空気流に悪影響を及ぼし騒音発生の原因となると
いう問題点があつた。 In this type of blower, a drain hole is provided on the underside of the motor to drain water that has entered the inside of the motor. However, since rainwater may infiltrate through this drain hole, in conventional systems, a pipe 100 as shown in FIG. 1 or 2 is attached to the drain hole. However, since this pipe 100 is arranged within the ventilation surface of the fan,
There was a problem that it adversely affected air flow and caused noise generation.
そこで、本発明者等はまず第３図Ａ，Ｂ第４図
Ａ，Ｂに示すような迷路構造部材２００を考え
た。これは通風面積内の投影面積を最少としたも
のであり、これにより上記騒音発生は防止され

ータとは別に設けられたものであるため、取り付
け等が煩雑であつた。 Therefore, the present inventors first considered a labyrinth structure member 200 as shown in FIGS. 3A and 4B. This minimizes the projected area within the ventilation area, thereby preventing the above-mentioned noise generation. However, since this maze structure member 200 is still provided separately from the motor, installation etc. are complicated.
本発明は、上記点に鑑みて案出されたもので、
フアンシユラウドに迷路構造を一体形成すること
により、上記迷路構造部材と同様の騒音低減効果
を発生しつつ、かつ取り付けを容易にすることを
目的とする。 The present invention was devised in view of the above points, and
By integrally forming a labyrinth structure on the fan shroud, the objective is to generate the same noise reduction effect as the labyrinth structure member described above and to facilitate installation.
以下本発明を図に示す実施例に基づいて説明す
る。 The present invention will be described below based on embodiments shown in the drawings.

フランジ部３ａ、及びフアン１を覆うシユラウド
部３ｂが設けられている。 In FIGS. 5 and 6, 1 is a resin fan, and 2 is a motor that rotationally drives the fan 1, which rotates in response to voltage from an on-vehicle battery (not shown). A fan shroud 3 is integrally formed of resin (polypropylene) containing 30% glass, and the fan shroud 3 is provided with a flange portion 3a for supporting the motor 2, and a shroud portion 3b for covering the fan 1.

るための取付部である。 That is, as shown in FIG. 6, a mounting flange 2a is provided on the outer surface of the motor, and this mounting flange 2a is fixed to a flange portion 3a of a fan shroud 3 with bolts 4. In addition,
3c is a stay that connects the flange portion of the fan shroud 3 and the shroud portion, and 3d is a mounting portion for attaching the fan shroud 3 to an automobile radiator (not shown).
モータ２にはそのシヤフト２ｂ部から雨水が侵

２ｃを鉄製モータハウジングを打ち抜いて形成し
ている。 Rainwater may enter the motor 2 through its shaft 2b. Furthermore, condensed water may be generated within the motor 2 due to rapid temperature fluctuations in the motor 2. Therefore, as shown in FIG. 7, a drain hole 2c is provided on the lower surface of the motor 2. The motor housing is made of iron, and therefore the drain hole 2c is formed by punching out the iron motor housing.

を与える障害部１０ｃが形成されている。 Further, a labyrinth structure 10 is integrally formed in a portion of the flange portion 3a of the fan shroud 3 that faces the drain hole 2c. Further, the motor housing has a recess 2 that accommodates the labyrinth structure 10.
d is formed. As shown in FIGS. 8 and 9, the labyrinth structure 10 has a cover 10a formed at a portion directly opposing the drain hole 2c, and a wind guide passage 10b formed on the side of the cover. ing. Furthermore, an obstruction portion 10c is formed in the middle of the air guiding passage 10b, which obstructs the wind passing through the passage.
従つて、フアンシユラウド外部の空気はこの障
害部１０ｃを避けつつ導風通路１０ｂ内を流れ

圧が生じるので一般に水抜き穴２ｃ近傍には雨水
が集まりやすいが、このように迷路構造部１０を
設けたことによりこの雨水が水抜き穴２ｃに侵入
するのが完全に防止される。 Therefore, the air outside the fan shroud flows through the air guide passage 10b while avoiding this obstacle 10c. Therefore, outside rainwater does not enter the drain hole 2c through the air guide passage 10b. In particular, when used in an automobile radiator as in this example, negative pressure is generated on the side wall of the motor as the fan 1 rotates, so generally rainwater tends to collect near the drain hole 2c. By providing the structure 10, this rainwater is completely prevented from entering the drain hole 2c.
なお、上述したのは本発明の望ましい実施例で
あるが、本発明は上記例以外にも種々の態様があ
る。 Although the above-described embodiments are preferred embodiments of the present invention, the present invention has various embodiments other than the above-described embodiments.

になつておればよい。 That is, the specific shape of the maze structure section 10 is
It is also possible to have a shape as shown in FIGS. The point is that the covering part 10a is provided on the part opposite the drain hole 2c, so that the drain hole 2c is not directly exposed to the atmosphere.
また上述の例は自動車用ラジエータに用いた例
を述べたが、本発明の送風機は他の例、例えば換
気扇等にも使用できる。 Furthermore, although the above-mentioned example is an example in which the blower is used in an automobile radiator, the blower of the present invention can also be used in other examples, such as a ventilation fan.

ない。 As explained above, in the blower according to the present invention, since the labyrinth structure is integrally formed in the fan shroud, it is possible to reliably prevent rainwater from entering the drain hole of the motor. Moreover, the work required to prevent this is simply to attach the motor to the fan shroud, which has the excellent effect of eliminating the need for any special attachment process. Further, since the mounting structure is integrally formed with the fan shroud and does not protrude into the ventilation area of the fan, the mounting structure does not obstruct ventilation and therefore does not cause noise generation.
