　以下、本開示の実施の形態について図面を参照して説明する。
　図１は、実施形態１に係る換気装置の設置状態の断面を示す断面図である。
　換気装置１００は、箱型の本体２と、この本体２内に組付けられた送風機１と、本体２の一側の排気口に装着されるダクト接続口８と、本体２の下面に装着される化粧グリル１２とから構成される。 Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing a cross section of the installed state of the ventilation device according to the first embodiment.
The ventilation device 100 is attached to the box-shaped main body 2, the blower 1 assembled in the main body 2, the duct connection port 8 attached to the exhaust port on one side of the main body 2, and the lower surface of the main body 2. It is composed of a decorative grill 12.
　ダクト接続口８は、屋外まで延びるダクト１４に接続される。ダクト１４は、建物の屋外外壁に備えたフードなどと連結し、住宅内の空気を換気する換気風路を形成する。ダクト接続口８は、径の異なる段状の外形を有している。ダクト接続口８の外形が径の異なる段状であることにより、径が異なるダクト１４に接続することが可能であるとともに、テーピングなどの作業性が向上する。ダクト接続口８内には、風圧にて開閉するシャッタ９が設けられている。シャッタ９は、換気装置１００の運転時には風圧で開き、停止時はシャッタ９の自重でダクト接続口８を閉鎖する。ダクト接続口８内にシャッタ９を設けることで、換気装置１００の停止時に屋外からの外風が室内に侵入するのを防止することができる。 The duct connection port 8 is connected to the duct 14 extending to the outside. The duct 14 is connected to a hood or the like provided on the outdoor outer wall of the building to form a ventilation air passage for ventilating the air in the house. The duct connection port 8 has a stepped outer shape having a different diameter. Since the outer shape of the duct connection port 8 is stepped with different diameters, it is possible to connect to ducts 14 having different diameters, and workability such as taping is improved. A shutter 9 that opens and closes by wind pressure is provided in the duct connection port 8. The shutter 9 is opened by wind pressure when the ventilation device 100 is operated, and the duct connection port 8 is closed by the weight of the shutter 9 when the ventilation device 100 is stopped. By providing the shutter 9 in the duct connection port 8, it is possible to prevent the outside wind from the outside from entering the room when the ventilation device 100 is stopped.
　本体２は、施工、点検、清掃などのメンテナンスを室内側から行なえるよう下面が開口している。本体２の下面の開口には、本体２の側壁から周囲に屈曲した本体フランジ２ａが設けられている。本体２は、天井２５に設けられた本体埋込穴２６に埋め込まれ、本体フランジ２ａに設けられたねじ穴などを通じて天井２５に固定される。 The lower surface of the main body 2 is open so that maintenance such as construction, inspection, and cleaning can be performed from the indoor side. The opening on the lower surface of the main body 2 is provided with a main body flange 2a bent from the side wall of the main body 2 to the periphery. The main body 2 is embedded in a main body embedding hole 26 provided in the ceiling 25, and is fixed to the ceiling 25 through a screw hole or the like provided in the main body flange 2a.
　本体２内に組付けられた送風機１は、モーター３と、モーター３の駆動軸に差込結合されたファン４とから構成されている。モーター３は、本体２の上面の天面２８に固定されている。また、モーター３は、ファン４を回転させることにより、本体２の下面の開口から排気口１０に向かう気流を形成する。なお、ファン４は、気流を形成できれば、例えば、シロッコファンやプロペラファンなど如何なる形状であってもよい。 The blower 1 assembled in the main body 2 is composed of a motor 3 and a fan 4 which is plugged and coupled to the drive shaft of the motor 3. The motor 3 is fixed to the top surface 28 on the upper surface of the main body 2. Further, the motor 3 forms an air flow from the opening on the lower surface of the main body 2 toward the exhaust port 10 by rotating the fan 4. The fan 4 may have any shape, for example, a sirocco fan or a propeller fan, as long as it can form an air flow.
　送風機１のファンケーシング６は、天面２８に固定され、下面に吸込口５を有する。ファンケーシング６の吸込口５は、本体２の下面の開口に位置する。吸込口５からファンケーシング６内に吸い込まれた空気は、送風機１によって排気口１０に送られ、ダクト接続口８及びダクト１４を介して屋外へ排気される。ファンケーシング６の開口側には、化粧グリル１２を取り付けるためのスプリング固定部７が形成されている。つまり、送風機１は、換気する空気を流通させる換気駆動体であり、吸込口５から本体２に流入した空気を、排気口１０から流出させる気流を形成する。 The fan casing 6 of the blower 1 is fixed to the top surface 28 and has a suction port 5 on the lower surface. The suction port 5 of the fan casing 6 is located at the opening on the lower surface of the main body 2. The air sucked into the fan casing 6 from the suction port 5 is sent to the exhaust port 10 by the blower 1, and is exhausted to the outside through the duct connection port 8 and the duct 14. A spring fixing portion 7 for attaching the decorative grill 12 is formed on the opening side of the fan casing 6. That is, the blower 1 is a ventilation drive body that circulates the ventilated air, and forms an air flow that causes the air that has flowed into the main body 2 from the suction port 5 to flow out from the exhaust port 10.
　化粧グリル１２には、室内空気を本体２内に吸い込むための吸込み口が形成されている。化粧グリル１２は、簡単に取り外せるように、換気装置１００に対して着脱自在に設けられている。具体的には、化粧グリル１２は、ファンケーシング６に設けられたスプリング固定部７にスプリング１３を引掛けることにより本体２に取付けられる。スプリング１３は、化粧グリル１２のスプリング固定部品２１に取付けられている。化粧グリル１２は、ファンケーシング６といった内部部品が見えて見栄えが悪くならないようにするため意匠部品である。 The decorative grill 12 is formed with a suction port for sucking indoor air into the main body 2. The decorative grill 12 is detachably provided with respect to the ventilation device 100 so that it can be easily removed. Specifically, the decorative grill 12 is attached to the main body 2 by hooking the spring 13 on the spring fixing portion 7 provided on the fan casing 6. The spring 13 is attached to the spring fixing component 21 of the decorative grill 12. The decorative grill 12 is a design part so that the internal parts such as the fan casing 6 are not visible and the appearance is not deteriorated.

Further, the locking portion 32 may lock the ground terminal 30 which is not tightened by the ground screw 31 at the mounting position of the ground terminal mounting surface 29. The mounting position is a position where the opening 39 of the ground terminal mounting surface 29 and the opening of the ground terminal 30 coincide with each other. With such a configuration, even when the main body 2 is installed on the ceiling 25 or a wall, the locking portion 32 can attach the ground terminal 30 which is not tightened by the ground screw 31 to the ground terminal mounting surface. By locking at the mounting position of 29, it is possible to prevent the ground terminal 30 from falling.
　図７は、アース端子の取り付け状態を示す断面図である。
　係止部３２は、一端が開放され、他端が立ち上がり部３４を介してアース端子取付面２９に設けられている。係止部３２の一端は、アースねじ３１を締め付ける回転方向とは逆方向に向かって延伸するように設けられている。また、係止部３２の他端である立ち上がり部３４は、アースねじ３１を締め付ける回転方向に向かってアース端子３０が回転することを規制する位置に設けられている。このように設けられた係止部３２にアース端子３０を係止することで、アース端子３０の落下を抑制することができる。また、立ち上がり部３４に接触してアース端子３０の回転を規制することができる。従って、アース端子３０の取り付け及び／又は取り外しに係る作業性を向上させることができる。このように、係止部３２がアース端子３０を抱え込む方向を、アースねじ３１を締め付ける回転方向と逆方向とすることで、アース端子３０の落下を抑制するだけでなく、回転も抑制することが可能となる。 FIG. 7 is a cross-sectional view showing an attached state of the ground terminal.
One end of the locking portion 32 is open, and the other end is provided on the ground terminal mounting surface 29 via the rising portion 34. One end of the locking portion 32 is provided so as to extend in a direction opposite to the rotation direction in which the ground screw 31 is tightened. Further, the rising portion 34, which is the other end of the locking portion 32, is provided at a position that restricts the rotation of the ground terminal 30 in the rotation direction in which the ground screw 31 is tightened. By locking the ground terminal 30 to the locking portion 32 provided in this way, it is possible to prevent the ground terminal 30 from falling. Further, the rotation of the ground terminal 30 can be regulated by contacting the rising portion 34. Therefore, the workability related to the attachment and / or removal of the ground terminal 30 can be improved. In this way, by setting the direction in which the locking portion 32 holds the ground terminal 30 in the direction opposite to the rotation direction in which the ground screw 31 is tightened, it is possible not only to suppress the fall of the ground terminal 30 but also to suppress the rotation. It will be possible.
　また、アース端子取付面２９には、アースねじ３１を締め付ける回転方向とは逆方向に向かってアース端子３０が回転することを規制する位置に突起３３が設けられている。具体的には、突起３３は、係止部３２の立ち上がり部３４が設けられていない側、即ち、係止部３２の開放された一端側のアース端子取付面２９に設けられている。このように、係止部３２の開側のアース端子取付面２９側に凸となる突起３３を設けることでアース端子３０の抜け止めを抑制することが可能となる。 Further, the ground terminal mounting surface 29 is provided with a protrusion 33 at a position that restricts the rotation of the ground terminal 30 in the direction opposite to the rotation direction in which the ground screw 31 is tightened. Specifically, the protrusion 33 is provided on the side where the rising portion 34 of the locking portion 32 is not provided, that is, on the ground terminal mounting surface 29 on the open one end side of the locking portion 32. In this way, by providing the convex protrusion 33 on the ground terminal mounting surface 29 side on the open side of the locking portion 32, it is possible to prevent the ground terminal 30 from coming off.
