Description

本発明は、居室内の高所に設置される送風機に関するものである。   The present invention relates to a blower installed at a high place in a living room.

従来、例えばダクト用換気扇において、下面が開口し天井の取付用開口部に挿入状態で配設される外箱内に、電動機及びこの電動機により駆動されるファンを設けると共に、そのファンを囲繞するようにプラスティック製のファンケーシングを設けるものにおいて、そのファンケーシングの外周部に下面に開口部を有する電装品収納部一体成形すると共に、モータのリード線を電源線に接続するための接続部を有した接続端子を上記電装品収納部にその接続部が上記開口部臨む状態で収納し、また、上記電装品収納部にこれの下面開口部開閉する蓋を回動可能に連結して設け、この蓋に、該蓋の開放状態で電装品収納部の開口部に下方から臨んで接続端子を受け止める凸部を設ける構成が知られている。   2. Description of the Related Art Conventionally, for example, in a duct ventilation fan, an electric motor and a fan driven by the electric motor are provided in an outer box that is opened in the lower surface and inserted into a mounting opening of a ceiling, and surrounds the fan. In the case where a plastic fan casing is provided, an electrical component housing portion having an opening on the lower surface is integrally formed on the outer periphery of the fan casing, and a connection portion for connecting the motor lead wire to the power supply line is provided. The connection terminal is stored in the electrical component storage portion with the connection portion facing the opening, and a lid that opens and closes the lower surface opening of the electrical component storage portion is rotatably connected. In addition, there is known a configuration in which a convex portion that receives a connection terminal from below is provided at the opening of the electrical component storage portion when the lid is open.

この構成によれば、接続端子に対する電源線の接続及び取り外しを室内側から行うことが出来ることにより、作業性が向上する。加えて、電装品収納部の開口部を開閉する蓋の内側に凸部を設けることで、蓋を開放しても接続端子が脱落することなく、電源線の接続、取り外し及び挿入確認の各作業を一層容易に行うことが可能となる。さらには、接続端子は凸部により制限されて所定以上引き出されることがないので、接続端子が接続されたモータのリード線に過大な張力がかかることなく、断線などの不具合を削減することができる(例えば、特許文献1参照)。   According to this configuration, the workability can be improved because the power supply line can be connected to and disconnected from the connection terminal from the indoor side. In addition, by providing a projection on the inside of the lid that opens and closes the opening of the electrical component storage section, the connection terminal is not dropped even if the lid is opened, and each operation of connecting, removing and inserting the power supply line is confirmed Can be performed more easily. Furthermore, since the connection terminal is limited by the convex portion and is not pulled out more than a predetermined amount, the lead wire of the motor to which the connection terminal is connected is not subjected to excessive tension, and problems such as disconnection can be reduced. (For example, refer to Patent Document 1).

登録実用新案第2538003号公報Registered Utility Model No. 2538003

上記従来の技術によれば、接続端子に対する電源線の取り付け及び取り外しは、外箱の下面の開口部を介して室内側から行うことができる。しかしながら、接続端子は開口部の内側にあって手が入りづらいので作業性が悪く改善が望まれていた。さらに上記従来の技術によれば、接続端子がそれ自体の自重で自由落下する危険性があると共に、接続端子に対する電源線の接続時、接続端子が固定されていないので、電源線を電源端子に差込む場合、接続端子が、奥側に退いてしまい電源線の接続施工が難しいという問題があった。このようにして、電源線の電気的接触が不十分になると安全上問題となるばかりか、ひいては火災の原因になることもあり、改善が望まれていた。さらには、電源線として、VVFケーブルを使用すると、内蔵の銅線が太く硬いため電源接続施工時に急激に曲げると折れてしまい接触不良を招く問題もあった。   According to the above conventional technique, the power supply line can be attached to and detached from the connection terminal from the indoor side through the opening on the lower surface of the outer box. However, since the connection terminal is inside the opening and it is difficult for the hand to enter, workability is poor and improvement is desired. Furthermore, according to the above-mentioned conventional technology, there is a risk that the connection terminal may fall freely due to its own weight, and the connection terminal is not fixed when the power supply line is connected to the connection terminal. When plugged in, there is a problem that the connection terminal is retracted to the back side and it is difficult to connect the power line. In this way, if the electrical contact of the power supply line becomes insufficient, it not only causes a safety problem, but also may cause a fire. Furthermore, when a VVF cable is used as a power supply line, the built-in copper wire is thick and hard, so there is a problem that it breaks when bent suddenly during construction of the power supply connection, resulting in poor contact.

When inserted into the quick-connect terminal, the fast-connect terminal is not retracted, and the power supply line can be connected well.

さらに、第3の本発明によれば、第2の本発明に加えて、さらに端子台がスライドするスライド台座のスライド面が、出入開口が形成された外箱の側面に対して傾斜しているので、装置の小型化が図れるとともに、電源線が曲がらなくてはならない角度を小さくすることができる。   Furthermore, according to the third aspect of the present invention, in addition to the second aspect of the present invention, the slide surface of the slide base on which the terminal block further slides is inclined with respect to the side surface of the outer box in which the access opening is formed. Therefore, the apparatus can be miniaturized and the angle at which the power line must be bent can be reduced.

また、第4の本発明によれば、従来ファン及び電動機の1組で1つのファンユニットとしていたものを、複数組で1つのファンユニットとし、さらに両者間に挟まれたネジにより外箱に共に締結されるので、必要とするネジの数量を削減することができる。   Further, according to the fourth aspect of the present invention, a conventional fan and electric motor set as one fan unit is changed into a plurality of sets as a single fan unit, and further, the screws are sandwiched between the two to the outer box. Since it is fastened, the required number of screws can be reduced.

図4は、送風機の分解斜視図である。外箱1内には、風路形成部材としてオリフィス部材36とエアーガイド部材37が収納されている。オリフィス部材36とエアーガイド部材37は、外箱1内に吸込口3から吹出口2に至る風路を形成している。エアーガイド部材37は、風路を上下に2分割する、風路は、外箱1の長手方向に並んで8個が形成されている。個々の風路に対応して、吸込口3から吹出口2へ空気を移動させるファン4と、このファン4を駆動する電動機5とが配設されている。風路形成部材であるオリフィス部材36とエアーガイド部材37は、2組のファン4及び電動機5を単位として分割されている。すなわち、2組のファン4及び電動機5と、これに対応するオリフィス部材36及びエアーガイド部材37とが、1つのファンユニット40を構成している。そして、外箱1内には、長手方向に並んで4個のファンユニット40が収納されている。   FIG. 4 is an exploded perspective view of the blower. In the outer box 1, an orifice member 36 and an air guide member 37 are accommodated as air path forming members. The orifice member 36 and the air guide member 37 form an air path from the inlet 3 to the outlet 2 in the outer box 1. The air guide member 37 divides the air path into two in the vertical direction. Eight air paths are formed side by side in the longitudinal direction of the outer box 1. Corresponding to each air path, a fan 4 for moving air from the suction port 3 to the blowout port 2 and an electric motor 5 for driving the fan 4 are arranged. The orifice member 36 and the air guide member 37 which are air path forming members are divided in units of two sets of the fan 4 and the electric motor 5. That is, the two sets of the fan 4 and the electric motor 5, the orifice member 36 and the air guide member 37 corresponding thereto constitute one fan unit 40. In the outer box 1, four fan units 40 are accommodated in the longitudinal direction.

長手方向に並ぶ4個のファンユニット40の吸込口側には、ファン4を保護する目的でガード38が設けられているが、このガードは連続する一枚の部材となっている。また、取付板7にて支持されるさい回動軸中心となる支持ボルト12が外箱1の側面1aに立設している。外箱1の長手方向両端には、概略断面L字型の取付板7とこの取付板7を覆う側部カバー8が設けられている。側部カバー8の大きさは、幅が80〜150mm、厚さが10〜70mmである。   On the suction port side of the four fan units 40 arranged in the longitudinal direction, a guard 38 is provided for the purpose of protecting the fan 4, and this guard is a continuous member. In addition, a support bolt 12 serving as the center of the rotation shaft when supported by the mounting plate 7 is erected on the side surface 1 a of the outer box 1. At both ends of the outer box 1 in the longitudinal direction, a mounting plate 7 having a substantially L-shaped cross section and a side cover 8 that covers the mounting plate 7 are provided. The side cover 8 has a width of 80 to 150 mm and a thickness of 10 to 70 mm.

図5は、送風機端部を側部カバー8を透過して見た図、図6は、図5と同じ部分を側部カバー8を透過して側方から見た図である。図7は、側部カバー8を外した送風機端部の斜視図、図8は、電源線の構造と三つ又に分割された端部の様子を示す斜視図である。取付板7は概略断面L字状を成し、天井面9に沿う締結部7bとこの締結部7bから直角に折れ曲がって下方に延びる本体部7aとから構成されている。本実施の形態の取付板7は、天井面9から下方に延びる吊りボルト15に締結部7bをナット16にて締結されて天井面9に固定されている。   FIG. 5 is a view of the blower end portion seen through the side cover 8, and FIG. 6 is a view of the same portion as FIG. 5 seen through the side cover 8 from the side. FIG. 7 is a perspective view of the blower end with the side cover 8 removed, and FIG. 8 is a perspective view showing the structure of the power supply line and the state of the end divided into three. The mounting plate 7 has a substantially L-shaped cross section, and includes a fastening portion 7b that extends along the ceiling surface 9 and a main body portion 7a that is bent at a right angle from the fastening portion 7b and extends downward. The mounting plate 7 of the present embodiment is fixed to the ceiling surface 9 by fastening a fastening portion 7 b with a nut 16 to a suspension bolt 15 extending downward from the ceiling surface 9.

取付板7は、本体部7aの下端部に穿孔された貫通穴に支持ボルト12を通して外箱1を回動可能に軸支している。本体部7aには、複数の角度調整穴7cが11.25度ピッチで円弧上に穿孔されており、いずれか1つを選択して角度調整ボルト14を止めることにより、図5に示す水平状態から吹出口2を鉛直下に向ける90度回動した位置と、逆に吹出口2を22.5度だけ上に向ける位置との間で角度を変えて設置できるようになっている。   The mounting plate 7 pivotally supports the outer box 1 through a support bolt 12 in a through hole drilled in the lower end of the main body 7a. In the main body 7a, a plurality of angle adjusting holes 7c are perforated on a circular arc at a pitch of 11.25 degrees, and by selecting any one and stopping the angle adjusting bolt 14, the horizontal state shown in FIG. The air outlet 2 can be installed by changing the angle between a position rotated 90 degrees so that the air outlet 2 is directed vertically downward and a position where the air outlet 2 is directed upward 22.5 degrees.

電動機5に電力を供給する電源線17が、天井側から延びて側部カバー8内を引き回されたのち外箱1内に挿入されている。電源線17は、図8に示すような3芯のVVFケーブルであり、3本の電線17aが横に並び被覆17bに覆われた断面偏平状を成すが、非常に剛性が高く、主面17cを含む平面内で湾曲(主面17cを湾曲させずに側方に湾曲)させようとしてもその方向には曲げ難い。そのため、電源線17は、主面17cを湾曲させる方向に曲げるか、またはそれに近い方向に曲げる。そして安全性を考慮して、VVFケーブルの電源線を曲げる場合には、電源線を破損することがないように、屈曲部の内側の半径が電源線の外径の6倍以上とするように電気設備に関する技術基準によって規定されている。   A power line 17 for supplying electric power to the electric motor 5 extends from the ceiling side and is routed through the side cover 8 and then inserted into the outer box 1. The power line 17 is a three-core VVF cable as shown in FIG. 8 and has a flat cross section in which the three electric wires 17a are arranged side by side and covered with the covering 17b. However, the power line 17 is very rigid and has a main surface 17c. Even if an attempt is made to bend within a plane including the main surface 17c (bend to the side without bending the main surface 17c), it is difficult to bend in that direction. Therefore, the power supply line 17 is bent in a direction in which the main surface 17c is bent or in a direction close thereto. In consideration of safety, when bending the power line of the VVF cable, the radius inside the bent part should be 6 times or more of the outer diameter of the power line so that the power line is not damaged. It is defined by technical standards for electrical equipment.

図7に示すように、電源線17は、天井側から側部カバー8内に入り、誘導フック26を通過の後、外箱1の側面1aに沿って下方に延び、円弧を下方に向けてフック型に大きく湾曲するとともに、外箱1から離れるように一旦浮き上がり、張力抑止部20を通ったのち反転して、誘導ポール19に接触しつつ外箱1側にひねりながら向きを変え、側面1aに固定された端子台カバー18の中央穴18aを通って外箱1内部に延びている。端子台カバー18奥の外箱1内の空間に図示しない端子台が収納されており、電源線17はこの端子台を介して電動機5のリード線と電気的に接続される。なお、端子台カバー18は、ネジ25aにより側面1aに固定され、電源線17の端子台への接続作業時には取り外される。   As shown in FIG. 7, the power line 17 enters the side cover 8 from the ceiling side, passes through the induction hook 26, extends downward along the side surface 1 a of the outer box 1, and turns the arc downward. It bends to a hook shape and floats away from the outer box 1, then reverses after passing through the tension restraining part 20, changes its direction while twisting toward the outer box 1 while touching the guide pole 19, It extends through the central hole 18a of the terminal block cover 18 fixed to the inside of the outer box 1. A terminal block (not shown) is accommodated in the space inside the outer box 1 behind the terminal block cover 18, and the power line 17 is electrically connected to the lead wire of the motor 5 through the terminal block. The terminal block cover 18 is fixed to the side surface 1a by screws 25a, and is removed when the power supply line 17 is connected to the terminal block.

張力抑止部20は、例えば電源線17が天井側に引っ張られたときに、その張力が端子台或いは端子台と電源線17との接続箇所におよばないようにするためのものであり、支持ボルト12に取付板7とともに共締めされて固定され、上部に設けられたコードクリップ21で電源線17を狭時する。コードクリップ21は、一旦を張力抑止部20に係合させ、他端を張力抑止部20にネジ25bにてネジ結合され、張力抑止部20との間に電源線17を挟みネジ25bにて締め付けることにより、電源線17を強くクランプする。張力抑止部20は、電源線17がフック型に大きく湾曲する途中に設けられているが、張力抑止部20がコードクリップ21にて電源線17を支持する支持面20aは、断面偏平状の電源線17が湾曲しやすくなる方向に傾斜している。すなわち、本実施の形態においては、外箱1の側面1aに対して電源線17の曲率半径方向外側に向けて起き上がるように15度傾斜している(図6)。   For example, when the power supply line 17 is pulled to the ceiling side, the tension suppression unit 20 is used to prevent the tension from reaching the terminal block or the connection point between the terminal block and the power supply line 17. The power supply line 17 is narrowed by a cord clip 21 which is fastened together with the attachment plate 7 to 12 and fixed at the top, and provided at the top. The cord clip 21 is once engaged with the tension restraining portion 20, the other end is screwed to the tension restraining portion 20 with a screw 25 b, and the power line 17 is sandwiched between the cord clip 21 and the tension restraining portion 20 and tightened with the screw 25 b. As a result, the power line 17 is strongly clamped. The tension suppression unit 20 is provided in the middle of the power supply line 17 being largely bent into a hook shape, but the support surface 20a on which the tension suppression unit 20 supports the power supply line 17 with the cord clip 21 is a power supply having a flat cross section. The line 17 is inclined in a direction in which it is easy to bend. That is, in the present embodiment, it is inclined 15 degrees so as to rise up toward the outer side in the radius of curvature of the power supply line 17 with respect to the side surface 1a of the outer box 1 (FIG. 6).

誘導フック26及び誘導ポール19は、外箱1の側面1aにて電源線17が所定の経路から大きく外れることなく引き回わされるように、電源線17の通過する位置を矯正している。つまり、誘導フック26と誘導ポール19は、電源線17が外箱1の側面1aにて所定の経路で引き回わされるように電源線17に接触して位置を矯正する位置決め部材を構成している。両者のうち特に誘導ポール19は、端子台カバー18と張力抑止部20との間で電源線17が湾曲する際の反力を受け、この誘導ポール19がないと電源線17が所定の形状に屈曲せず、本実施の形態の構造においては無くてはならない部材である。   The guide hook 26 and the guide pole 19 correct the position through which the power supply line 17 passes so that the power supply line 17 is routed around the side surface 1a of the outer box 1 without greatly deviating from a predetermined path. That is, the induction hook 26 and the induction pole 19 constitute a positioning member that contacts the power supply line 17 and corrects the position so that the power supply line 17 is routed along a predetermined path on the side surface 1a of the outer box 1. ing. In particular, the induction pole 19 is subjected to a reaction force when the power line 17 is bent between the terminal block cover 18 and the tension restraining portion 20, and without the induction pole 19, the power line 17 has a predetermined shape. It is a member that does not bend and is indispensable in the structure of the present embodiment.

図9は、端子台カバー18が外されて、外箱1の側面1aに形成された出入開口から端子台が見える様子を示す正面図、図10は、出入開口内の端子台の様子を示す斜視図、図11は、端子台が接続作業位置に引き出された様子を示す断面図、図12は、端子台が収納位置にある様子を示す断面図である。外箱1の端部空間に端子台11が収納されている。端子台11は上面に搭載した速結端子(接続端子)10を含んで構成されている。   FIG. 9 is a front view showing a state where the terminal block cover 18 is removed and the terminal block can be seen from the entrance / exit opening formed on the side surface 1a of the outer box 1, and FIG. 10 shows the state of the terminal block inside the entrance / exit opening. FIG. 11 is a cross-sectional view showing a state in which the terminal block is pulled out to the connection work position, and FIG. 12 is a cross-sectional view showing a state in which the terminal block is in the storage position. A terminal block 11 is accommodated in the end space of the outer box 1. The terminal block 11 includes a quick connection terminal (connection terminal) 10 mounted on the upper surface.

速結端子10は、電源線17の3本の電線17aがそれぞれ挿入される3つの挿入口10aを有している。3つの挿入口10aは、速結端子10の出入開口1bに臨む面に開口し後述するスライド方向に延びている。速結端子10は、電線17aを挿入口10aから差し入れると図示しない内部のくわえ込み構造が動作して、これにより電線17aが狭持されて、その後電線17aを引き抜く方向に力を加えても引き抜けないという構造のものである。   The quick connection terminal 10 has three insertion ports 10a into which the three electric wires 17a of the power supply line 17 are respectively inserted. The three insertion openings 10a are opened on the surface facing the entrance / exit opening 1b of the quick connection terminal 10 and extend in a sliding direction to be described later. The quick connection terminal 10 can operate even when a force is applied in the direction of pulling out the electric wire 17a after the electric wire 17a is inserted from the insertion port 10a and an internal holding structure (not shown) is operated. It has a structure that cannot be pulled out.

外箱1の端部空間にスライド台座24が設けられている。端子台11は、スライド台座24上に形成されたスライド面24a上に載置され、スライド可能となっている。詳細には、端子台11は、外箱1に形成された出入開口1bから、速結端子10前側の挿入口10aを含む一部を出現させる接続作業位置D(図11)と、外箱1内に全体が収納される収納位置E(図12)との間をスライド可能とされている。そして、スライド台座24のスライド面24aは、出入開口1bが形成された外箱1の側壁(側面1aを形成する外箱1の壁)に対して傾斜している。スライド面24aの傾斜は、電源線17が曲がらなくてはならない角度を小さくする方向(電源線17の曲がる角度が大きくなる、つまり直線に近づく方向)に傾斜し、その傾斜の大きさは、端子台11を外箱1内に収納する構造と、端子台11の出没動作と、接続作業の行い安さとを考慮して最適な角度になっている。本実施の形態の場合、スライド面24aの傾斜は、例えば送風機100が水平に設置された場合に、出入開口1bから奥に向かって上るように約30度の傾斜である。   A slide base 24 is provided in the end space of the outer box 1. The terminal block 11 is placed on a slide surface 24a formed on the slide base 24 and is slidable. Specifically, the terminal block 11 includes a connection work position D (FIG. 11) in which a part including the insertion port 10 a on the front side of the quick connection terminal 10 appears from the access opening 1 b formed in the outer box 1, and the outer box 1. It is slidable between a storage position E (FIG. 12) in which the entirety is stored. The slide surface 24a of the slide base 24 is inclined with respect to the side wall (wall of the outer box 1 forming the side surface 1a) of the outer box 1 in which the entrance / exit opening 1b is formed. The inclination of the slide surface 24a is inclined in a direction in which the angle at which the power supply line 17 has to bend is reduced (the angle at which the power supply line 17 is bent, that is, in a direction approaching a straight line). The angle is optimal in consideration of the structure in which the base 11 is accommodated in the outer box 1, the movement of the terminal block 11, and the ease of connection work. In the case of the present embodiment, the inclination of the slide surface 24a is, for example, an inclination of about 30 degrees so as to rise from the entrance / exit opening 1b toward the back when the blower 100 is installed horizontally.

端子台11は、例えば平板部材を折り曲げることにより作製され、中央部主面上に速結端子10を搭載している。そして、端子台11のスライド方向前側は、二股に分割されて先端部がそれぞれ段状に折り曲げられて取っ手部11aとなっている。また、端子台11のスライド方向後側は、速結端子10を超える高さまで折り曲げられて立ち上がり部11bが形成されている。そしてさらに、端子台11が接続作業位置Dに有るときに、端子台11の立ち上がり部11bと係合して端子台11を接続作業位置Dに保持する段部(ストッパ)24cが、速結端子10の上方に設けられている。   The terminal block 11 is produced, for example, by bending a flat plate member, and the quick connection terminal 10 is mounted on the central main surface. The front side of the terminal block 11 in the sliding direction is divided into two parts, and the tip part is bent in a step shape to form a handle part 11a. Further, the rear side of the terminal block 11 in the sliding direction is bent to a height exceeding the quick connection terminal 10 to form a rising portion 11b. Further, when the terminal block 11 is at the connection work position D, a step portion (stopper) 24c that engages with the rising portion 11b of the terminal block 11 and holds the terminal block 11 at the connection work position D is provided with the quick connection terminal. 10 is provided above.

電源接続施工時においては、電源施工者は、端子台カバー18を外したのち、取っ手部11aをつかみ端子台11を接続作業位置Dまで引き出す。次いでこの位置で、取っ手部11aをつかみ下方へ引き下げると、端子台11が、支点24bを中心として回動する。そして、立ち上がり部11bが上がり、段部(ストッパ)24cに係合して保持される。これにより、電線17aを速結端子10に挿入するとき、速結端子10が退いてしまうことがなく、良好に電源線17の接続作業が行われる。接続作業を終えると、上記と逆の手順により、取っ手部11aを上方に引き上げて段部24cとの係合を外し、収納位置Eに押し込んで端子台カバー18にて蓋をする。なお、本実施の形態において、段部(ストッパ)24cは、速結端子10の上方に設けられているが、これに限らず例えばスライド面24a奥側に段部として形成して、取っ手部11aを上方に引き上げることにより、端子台11後端を係合させるようなものであってもよい。なお、端子台11を引き出す際、端子台11全体が引き抜けてしまうことを防止する構造としては、端子台11の中間部より後方の部分の幅を出入開口1bの幅より大きくすることにより実現している。   At the time of power supply connection construction, the power supply builder removes the terminal block cover 18, and then grasps the handle portion 11 a and pulls out the terminal block 11 to the connection work position D. Next, at this position, when the handle portion 11a is grasped and pulled downward, the terminal block 11 rotates about the fulcrum 24b. Then, the rising portion 11b rises and is held in engagement with the stepped portion (stopper) 24c. Thereby, when inserting the electric wire 17a in the quick connection terminal 10, the quick connection terminal 10 is not retracted, but the connection operation of the power wire 17 is performed favorably. When the connection work is completed, the handle portion 11a is pulled upward to disengage from the stepped portion 24c, pushed into the storage position E, and covered with the terminal block cover 18 by a procedure reverse to the above. In the present embodiment, the stepped portion (stopper) 24c is provided above the quick-connect terminal 10. However, the stepped portion (stopper) 24c is not limited to this and is formed as a stepped portion on the back side of the slide surface 24a, for example, and the handle portion 11a. The rear end of the terminal block 11 may be engaged by pulling upward. In addition, when pulling out the terminal block 11, the structure for preventing the entire terminal block 11 from being pulled out is realized by making the width of the rear portion of the intermediate portion of the terminal block 11 larger than the width of the access opening 1b. doing.

このように、本実施の形態の送風機100によれば、端子台11が外箱1の側面1aに形成された出入開口1bから出没するので、電源線17を接続する際には、接続作業位置Dに引き出して作業性を良くするとともに、接続終了後には収納位置Eに収納して防火安全対策を十分なものとすることができる。また、端子台11が接続作業位置Dに有るときに、端子台11と係合して、端子台11が収納位置E側に退くことを防止する段部(ストッパ)24cが設けられているので、VVFケーブルのような剛性の大きいケーブルであっても、速結端子10に挿入するとき、速結端子10が退いてしまうことがなく、良好に電源線17の接続作業を行うことができる。さらに、端子台11のスライド方向前側に取っ手部11aが設けられているので、端子台11を引き出しやすい。さらにまた、スライド台座24のスライド面24aは、出入開口1bが形成された外箱1の側面1aに対して傾斜しているので、外箱1内に長手方向に必要とする空間を小さくして小型化を図ることができるとともに、電源線17が曲がらなくてはならない角度を小さくする。   Thus, according to the blower 100 of the present embodiment, the terminal block 11 protrudes and retracts from the access opening 1b formed in the side surface 1a of the outer box 1, so that when connecting the power line 17, the connection work position It can be pulled out to D to improve workability, and after connection is completed, it can be stored in the storage position E to ensure sufficient fire safety. Further, when the terminal block 11 is in the connection work position D, a step portion (stopper) 24c that engages with the terminal block 11 and prevents the terminal block 11 from retracting toward the storage position E side is provided. Even when the cable is highly rigid such as a VVF cable, the quick connection terminal 10 is not retracted when inserted into the quick connection terminal 10, and the connection work of the power line 17 can be performed satisfactorily. Furthermore, since the handle portion 11a is provided on the front side in the sliding direction of the terminal block 11, the terminal block 11 can be easily pulled out. Furthermore, since the slide surface 24a of the slide base 24 is inclined with respect to the side surface 1a of the outer box 1 in which the access opening 1b is formed, the space required in the longitudinal direction in the outer box 1 is reduced. The angle can be reduced, and the angle at which the power line 17 must be bent is reduced.

側部カバー8の固定方法について記載する。図13は、側部カバー8を裏面側から見た斜視図である。外箱1の両端部には、意匠性を考慮して、それぞれ側部カバー8が設けられている。側部カバー8は、裏面下部に立設する円筒状の挿入ガイド8bに、外箱1に立設する支持ボルト12(図5,6)を挿入させ、これをガイドとして外箱1に向けて平行に移動し、裏面上部に立設された弾力性を持つ係合突起8aを、取付板7上部に形成された係合穴7d(図5,6)に押し込んでくわえ込ませ、さらに短手方向両側部に設けた一対の磁石29により取付板7を吸着して取り付けられている。   A method for fixing the side cover 8 will be described. FIG. 13 is a perspective view of the side cover 8 as seen from the back side. Side covers 8 are provided at both ends of the outer box 1 in consideration of design. The side cover 8 is inserted into a cylindrical insertion guide 8b erected at the lower part of the back surface, and a support bolt 12 (FIGS. 5 and 6) erected on the outer box 1 is inserted toward the outer box 1 using this as a guide. The elastic engaging protrusion 8a which moves in parallel and is erected on the upper surface of the back surface is pushed into an engaging hole 7d (FIGS. 5 and 6) formed in the upper portion of the mounting plate 7, and is further shortened. The mounting plate 7 is attracted and attached by a pair of magnets 29 provided on both sides in the direction.

従来、一般的な機器の意匠性カバー取り付け方法にあっては、磁石によるものも提案されている。磁石の吸着力によりカバーを固定するので、ネジ止め等が必要なく、取り付け取り外しは容易なものとなる。しかしながら、経年変化により磁石の吸着力が劣化した場合に、この吸着が外れカバーが脱落してしまう心配があった。   Conventionally, as a method for attaching a designable cover for a general device, a method using a magnet has been proposed. Since the cover is fixed by the attractive force of the magnet, screwing or the like is not required, and attachment and removal are easy. However, when the magnet's attracting force deteriorates due to secular change, there is a concern that this attracting may come off and the cover may fall off.

本実施の形態においては、上記ような構造とすることで、取り付けネジを不要とするとともに、取り付け取り外し工程を容易なものとして作業性を高めている。また、係合突起8a及び挿入ガイド8bによるスライド押し込み構造と一対の磁石29を併用したことにより、万一、磁石29の吸着が外れても、スライド押し込み構造により側部カバー8が落下することがなく、逆に係合突起8aや挿入ガイド8bが外れたり破損したりしても、磁石29により側部カバー8が落下することがない。なお、側部カバー8の側部には、取り外し方向が容易に分かるように、その方向を示す印(矢印)31が刻印されている(図7)。   In the present embodiment, the structure as described above eliminates the need for a mounting screw and facilitates the mounting / removing process to improve workability. In addition, by using the slide push-in structure with the engagement protrusion 8a and the insertion guide 8b and the pair of magnets 29, the side cover 8 may fall due to the slide push-in structure even if the magnet 29 is removed. On the contrary, the side cover 8 is not dropped by the magnet 29 even if the engagement protrusion 8a or the insertion guide 8b is detached or damaged. In addition, the side (arrow) 31 which shows the direction is stamped on the side part of the side cover 8 so that a removal direction can be understood easily (FIG. 7).

次に、ファンユニット40の外箱1への固定方法について説明する。本実施の形態の固定方法においては、使用するネジの数量を大幅に削減する。図14は、ファンユニット40が外箱1に組み付けられる様子を示す斜視図、図15は、本実施の形態によりネジの数量が削減されたネジ位置を示す模式図である。図16は、比較のために示す従来のファンユニットに使用されていたネジのネジ位置を示す模式図である。図17は、図14の図中G位置において、隣り合う2つのファンユニットが1本のネジにより共締めされる様子を示す概略図である。図18は、図17における第1オリフィス部材と第2オリフィス部材のみの斜視図である。図19は、図14に示されたファンユニットの端部を拡大して示す斜視図である。   Next, a method for fixing the fan unit 40 to the outer box 1 will be described. In the fixing method of this embodiment, the number of screws to be used is greatly reduced. FIG. 14 is a perspective view showing how the fan unit 40 is assembled to the outer box 1, and FIG. 15 is a schematic view showing screw positions where the number of screws is reduced according to the present embodiment. FIG. 16 is a schematic diagram showing screw positions of screws used in a conventional fan unit shown for comparison. FIG. 17 is a schematic view showing a state where two adjacent fan units are fastened together by one screw at a position G in FIG. FIG. 18 is a perspective view of only the first orifice member and the second orifice member in FIG. FIG. 19 is an enlarged perspective view showing an end portion of the fan unit shown in FIG.

ファンユニット40は、冒頭でも述べたように、2組のファン4及び電動機5と、これに対応する大きさのオリフィス部材36及びエアーガイド部材37とによって、1つのファンユニット40が構成されている。そして外箱1内には、長手方向に並ぶように4個のファンユニット40が収納されている。4個のファンユニット40は、それぞれネジ25cとネジ25dにより外箱1に締結されている。ネジ25cは、各ファンユニット40の両端上部角部を外箱1に締結する。一方、ネジ25dは、各ファンユニット40の中央下部を外箱1に締結する(図14、図15)。なお、図14においては、1本のネジ25cと1本のネジ25dのみを記載し他のネジは省略している。   As described in the introduction, the fan unit 40 includes the two fans 4 and the electric motor 5, and the orifice member 36 and the air guide member 37 having a size corresponding to the two fans 4 and the electric motor 5. . In the outer box 1, four fan units 40 are accommodated in the longitudinal direction. The four fan units 40 are fastened to the outer box 1 by screws 25c and 25d, respectively. The screws 25 c fasten the upper corners of both ends of each fan unit 40 to the outer box 1. On the other hand, the screw 25d fastens the center lower part of each fan unit 40 to the outer box 1 (FIGS. 14 and 15). In FIG. 14, only one screw 25c and one screw 25d are shown, and the other screws are omitted.

図16に示すように、従来1組のファン4及び電動機と、これに対応する大きさのオリフィス部材及びエアーガイド部材とで1つのファンユニットが構成されていた。締結用のネジ25は、各角部に1個計4個が1個のファンユニットに設けられていた。そのため、装備するファンユニットの数量が増えると締結用のネジ25の数は、膨大なものとなっていた。これと比較して明かなように、本実施の形態のファンユニット40の固定方法においては、使用するネジの数量を大幅に削減する。以下これについて説明する。   As shown in FIG. 16, a conventional fan unit is composed of a set of fan 4 and electric motor, and an orifice member and an air guide member having a size corresponding thereto. A total of four fastening screws 25 are provided in one fan unit at each corner. Therefore, when the number of fan units to be equipped is increased, the number of fastening screws 25 is enormous. As is clear from this, the number of screws to be used is greatly reduced in the fixing method of the fan unit 40 of the present embodiment. This will be described below.

ここでは、隣り合う2つのファンユニット40を、仮に第1ファンユニット40A及び第2ファンユニット40Bとして説明する。第1ファンユニット40Aと第2ファンユニット40Bのオリフィス部材である第1オリフィス部材36Aと第2オリフィス部材36Bの互いに対向する端部の上部角部(図14中Gの部分)には、円筒状のネジ穴が軸に沿って2片に分割されたような形状の分割ネジ穴片47A,47Bがそれぞれ設けられている。分割ネジ穴片47A,47Bは、相互に突き合わされて円筒状のネジ穴を形成する。また、この角部の裏面には、外箱1側に突出する突起46A,46Bがそれぞれ設けられている。一方、これに対応する外箱1の開口縁部においては、分割ネジ穴片47A,47Bが形成するネジ穴の位置に雌ねじ穴42が螺刻され、突起46Aの位置に貫通穴33が開口され、突起46Bの位置に長穴34が開口されている。   Here, two adjacent fan units 40 will be described as a first fan unit 40A and a second fan unit 40B. An upper corner (a portion G in FIG. 14) of the opposite ends of the first orifice member 36A and the second orifice member 36B, which are orifice members of the first fan unit 40A and the second fan unit 40B, is cylindrical. Are provided with split screw hole pieces 47A and 47B each having a shape in which the screw holes are divided into two pieces along the axis. The divided screw hole pieces 47A and 47B are abutted with each other to form a cylindrical screw hole. In addition, protrusions 46A and 46B projecting toward the outer box 1 are provided on the rear surfaces of the corners. On the other hand, in the opening edge portion of the outer box 1 corresponding to this, the female screw hole 42 is screwed at the position of the screw hole formed by the divided screw hole pieces 47A and 47B, and the through hole 33 is opened at the position of the protrusion 46A. A long hole 34 is opened at the position of the protrusion 46B.

貫通穴33と長穴34とは、それぞれ突起46A,46Bと係合する。これにより、第1オリフィス部材36Aと第2オリフィス部材36Bとが離間することが規制される。この状態にて、分割ネジ穴片47A,47Bが形成するネジ穴に挿入された1本のネジ25cにより、第1オリフィス部材36Aと第2オリフィス部材36Bとが共締めされる。突起46Bに対応する穴が長穴なのは、オリフィス部材36の成形精度や組立誤差を考慮してのものである。なお、貫通穴33と長穴34、及び突起46A,46Bが構成する係合・被係合の構造に関しては、オリフィス部材36A,36B側に穴が開口されて外箱1側に突起が設けられてもよい。   The through hole 33 and the long hole 34 engage with the protrusions 46A and 46B, respectively. As a result, the separation of the first orifice member 36A and the second orifice member 36B is restricted. In this state, the first orifice member 36A and the second orifice member 36B are fastened together by one screw 25c inserted into the screw hole formed by the divided screw hole pieces 47A and 47B. The hole corresponding to the protrusion 46B is a long hole in consideration of the molding accuracy of the orifice member 36 and assembly errors. As for the engagement / engagement structure formed by the through hole 33, the long hole 34, and the protrusions 46A, 46B, a hole is opened on the orifice member 36A, 36B side and a protrusion is provided on the outer box 1 side. May be.

オリフィス部材36とエアーガイド部材37との結合に関しては、図19に示すように、オリフィス部材36の上面からエアーガイド部材37方向に延びる延出部の先端に形成された係合穴35がエアーガイド部材37の上面に形成された係合凸部43に係合することにより行われる。この係合穴35と係合凸部43の係合構造は、オリフィス部材36とエアーガイド部材37の裏面側にも同様に設けられている。このようにオリフィス部材36とエアーガイド部材37とが結合されて、ファンユニット40が組み立てられる。   As shown in FIG. 19, the engagement hole 35 formed at the tip of the extending portion extending from the upper surface of the orifice member 36 toward the air guide member 37 is connected to the air guide member 37 with respect to the connection between the orifice member 36 and the air guide member 37. This is performed by engaging with an engaging projection 43 formed on the upper surface of the member 37. The engagement structure of the engagement hole 35 and the engagement convex portion 43 is similarly provided on the back surfaces of the orifice member 36 and the air guide member 37. In this way, the orifice member 36 and the air guide member 37 are coupled, and the fan unit 40 is assembled.

エアーガイド部材37の上部と下部には風路を形成する風路壁37a,37aが対を成して設けられている。一方、オリフィス部材36の上部と下部にも風路を形成する勘合壁36a,36aが対を成して設けられている。両勘合壁36a,36a及び勘合壁36a,36aは、互いに一部を重ね合わせ吸込口3から吹出口2へ至る風路を形成する。つまり、吸込口3からファン4により吸い込まれた空気は、その後、オリフィス部材36とエアーガイド部材37とにより、装置の上下に分岐して、2段となっている吹出口2から吹き出す(図1)。   Air passage walls 37a and 37a forming air passages are provided in pairs at the upper and lower portions of the air guide member 37. On the other hand, mating walls 36a and 36a that form air passages are also provided in pairs at the upper and lower portions of the orifice member 36. Both the fitting walls 36a and 36a and the fitting walls 36a and 36a are partially overlapped to form an air passage from the suction port 3 to the blower outlet 2. That is, the air sucked by the fan 4 from the suction port 3 is then branched up and down by the orifice member 36 and the air guide member 37 and blown out from the two-stage air outlet 2 (FIG. 1). ).

ガード38とオリフィス部材36(ファンユニット40)との結合に関しては、図19に示すように、ガード38の上角部からオリフィス部材36に向かって延びる突出部が設けられており、この突出部の先端に形成された係合爪45が、オリフィス部材36の対向面上角部に形成された係合穴41に係合することにより行われる。この係合爪45と係合穴41の係合構造は、ガード38とオリフィス部材36の対向面の他の3つの角部にも同様に設けられている。このようにして結合されたガード38とオリフィス部材36(ファンユニット40)とがネジ25dにより、外箱1に締結される(図14)。   With respect to the connection between the guard 38 and the orifice member 36 (fan unit 40), as shown in FIG. 19, a protrusion extending from the upper corner of the guard 38 toward the orifice member 36 is provided. The engagement claw 45 formed at the tip is engaged with the engagement hole 41 formed in the upper corner portion of the facing surface of the orifice member 36. The engagement structure of the engagement claw 45 and the engagement hole 41 is similarly provided at the other three corners of the opposing surfaces of the guard 38 and the orifice member 36. The guard 38 and the orifice member 36 (fan unit 40) combined in this way are fastened to the outer box 1 by screws 25d (FIG. 14).
