また、ハウジング１６の内部に係止部１９を設けることにより、モータ３の外周側へ突出しなくコンパクトな形状にすることができ、結果、風の通る風路を邪魔するコネクタ９の突出を少なくすることにより性能の悪化を抑制することができる。 Further, by providing the locking portion 19 inside the housing 16, it can be made compact without protruding to the outer peripheral side of the motor 3, and as a result, the protrusion of the connector 9 that obstructs the air passage through which the wind passes is reduced. As a result, deterioration of performance can be suppressed.

また、屋根部１５をモータ外郭１４に密着するフランジ部２０とその他の部分で構成し、フランジ部２０の幅寸法Ａ２１が開口８の幅寸法Ｂ２２よりも大きい構成とし、その他の部分の幅寸法Ｃ２３がハウジング１６の幅寸法Ｄ２４よりも小さく、壁部の幅寸法Ｅ２５よりも大きくすることで、例えばメンテナンス時にコネクタ９をモータ３から取り外す際に、カバー１７だけを保持してしまうことを防ぎ、容易にコネクタ９をモータ３から取り外すことができる。 Further, the roof portion 15 is composed of the flange portion 20 that is in close contact with the motor outer shell 14 and other portions, the width portion A21 of the flange portion 20 is larger than the width size B22 of the opening 8, and the width portion C23 of the other portion. Is smaller than the width dimension D24 of the housing 16 and larger than the width dimension E25 of the wall portion, for example, when removing the connector 9 from the motor 3 during maintenance, for example, it is easy to prevent the cover 17 from being held. The connector 9 can be detached from the motor 3.

また、屋根部１５の両側に側面カバー部２６を設けることにより、ハウジング１６とカバー１７とのクリアランスを小さくすることで、埃等の異物が浸入することを防ぎ、また、ハウジング１６と側面カバー部２６の間に隙間を設けることで、ハウジング１６とカバー１７の間に水が滞留してしまうことを防ぐことができ、モータ３内部への水の浸入を防止することができる。 Further, by providing the side cover portions 26 on both sides of the roof portion 15, the clearance between the housing 16 and the cover 17 is reduced to prevent foreign matters such as dust from entering, and the housing 16 and the side cover portions. By providing a gap between the housings 26, it is possible to prevent water from staying between the housing 16 and the cover 17, and to prevent water from entering the motor 3.

また、ハウジング１６の天面２７に外側に向けた傾斜をつけることで、天面２７に水が滞留することを防ぐことで、モータ３内部への水の浸入を防止することができる。 In addition, by inclining the top surface 27 of the housing 16 toward the outside, water can be prevented from staying on the top surface 27, thereby preventing water from entering the motor 3.

本発明にかかる換気装置は、モータ内部への異物の侵入を防ぎ異常な音の発生等を防止することができることを可能とするものであるので、壁面または天井に設置され、屋外と連通するダクトに接続され、室内の換気を行う空気調和機等として有用である。 Since the ventilator according to the present invention is capable of preventing foreign matter from entering the motor and preventing abnormal sounds, etc., the ventilator is installed on the wall surface or ceiling and communicates with the outside. And is useful as an air conditioner for ventilating the room.
