Description
【0001】[0001]
本発明は、天井面あるいは室壁に設けられた開口に挿入設置され、室内の汚れ た空気を排出する換気装置に関するものである。 The present invention relates to a ventilation device that is inserted and installed in an opening provided on a ceiling surface or a room wall and discharges dirty air in a room.
【0002】[0002]
従来、この種の換気装置は、たとえば実開平3−111842号公報に示すよ うな構成が一般的であった。以下、その構成について図3〜図5を参照しながら 説明する。 Heretofore, this type of ventilator has generally been configured, for example, as disclosed in Japanese Utility Model Laid-Open No. 3-111842. The configuration will be described below with reference to FIGS.
【0003】 図に示すように、101はファン102とモータ103などを備え、下面に吸 込口104と、側面に吐出口105とを有する箱状外郭106からなる本体であ り、吸込口104の周囲には複数の取り付け穴107を有するフランジ部108 が設けられている。そしてフランジ部108の取り付け穴107の下部には、次 に説明する取り付け用ねじ保持具113が設けられている。この取り付け用ねじ 保持具113は、取り付け穴107に連通する孔部113Aを有した筒部112 の上端部に、フランジ部108の取り付け穴107の外周へ粘着剤等で固定され る取り付け板109を有するとともに、筒部112の垂直方向に複数条の溝11 0と、下端部に取り付けねじ116を仮固定するための複数の爪111とを有し ている。As shown in the figure, 101 is a main body including a fan 102, a motor 103, etc., and a box-shaped outer casing 106 having a suction port 104 on the lower surface and a discharge port 105 on the side surface. A flange portion 108 having a plurality of mounting holes 107 is provided around the. An attachment screw holder 113, which will be described below, is provided below the attachment hole 107 of the flange portion 108. This attachment screw holder 113 has an attachment plate 109 fixed to the outer periphery of the attachment hole 107 of the flange portion 108 with an adhesive or the like at the upper end of a tubular portion 112 having a hole portion 113A communicating with the attachment hole 107. In addition, it has a plurality of grooves 110 in the vertical direction of the tubular portion 112 and a plurality of claws 111 for temporarily fixing the mounting screw 116 to the lower end portion.
【0004】 上記構成において、換気装置を天井115に取り付けるには、あらかじめ本体 1の箱状外郭106のフランジ部108に、粘着剤等で取り付け用ねじ保持具1 13の取り付け板109を接合して取り付けるとともに、取り付け用ねじ保持具 113に固定ねじ116を仮固定しておき、本体101を天井115の取り付け 位置に片方の手118で支持し、もう片方の手118でドライバー117を持っ て、取り付けねじ116をフランジ部の取り付け穴107を通して木枠114に 締め付けることによって、取付工事を一人で行ない施工作業効率を向上させるも のであった。In the above structure, in order to mount the ventilation device on the ceiling 115, the mounting plate 109 of the mounting screw holder 113 is bonded to the flange portion 108 of the box-shaped outer casing 106 of the main body 1 in advance with an adhesive or the like. In addition to mounting, the fixing screw 116 is temporarily fixed to the mounting screw holder 113, the main body 101 is supported at the mounting position of the ceiling 115 with one hand 118, and the driver 117 is held with the other hand 118 to mount. By tightening the screws 116 to the wooden frame 114 through the mounting holes 107 in the flange portion, the mounting work can be performed by one person to improve the construction work efficiency.
【0005】[0005]
このような従来の換気装置では、取り付け用ねじ保持具113の筒部112の 垂直方向に溝110が設けられているので、本体101を天井115に固定する 際、取り付けねじ116を締めこんで行くと取り付け用ねじ保持具113の筒部 112が外方向に向かって広がっていき、本体101をしっかりと固定すること ができなかったり、取り付け用ねじ保持具113が本体101と別部品になって いるので、紛失してしまうことがあるという課題があった。 In such a conventional ventilation device, since the groove 110 is provided in the vertical direction of the cylindrical portion 112 of the mounting screw holder 113, the mounting screw 116 is tightened when the main body 101 is fixed to the ceiling 115. And the cylindrical portion 112 of the mounting screw holder 113 expands outward, and the main body 101 cannot be firmly fixed, or the mounting screw holder 113 is a separate part from the main body 101. Therefore, there was a problem that it might be lost.
【0006】 本考案は上記課題を解決するもので、施工性を損なうことなく本体を天井にし っかり固定するとともに、取り付け用ねじ保持具の紛失を確実に防止することの できる換気装置を提供することを目的としている。The present invention solves the above problems, and provides a ventilation device capable of securely fixing the main body to the ceiling without impairing the workability and reliably preventing the attachment screw holder from being lost. Is intended.
【0007】[0007]
本考案は上記の目的を達成するために、天井面あるいは室壁に設けられた開口 に挿入される筒状で、前記開口の周縁に固定ねじで固定されるフランジ部を有し た本体と、この本体の内部に配設される送風機とを備え、前記フランジ部は前記 固定ねじを挿通する複数の固定孔を有し、この固定孔の径を前記固定ねじの外径 寸法より前方側で小さく後方側で大きく形成した換気装置の構成としたものであ る。 In order to achieve the above object, the present invention has a main body having a cylindrical shape which is inserted into an opening provided in a ceiling surface or a room wall and has a flange portion fixed to the peripheral edge of the opening with a fixing screw, The main body includes a blower disposed inside the main body, and the flange portion has a plurality of fixing holes through which the fixing screws are inserted, and the diameter of the fixing holes is smaller on the front side than the outer diameter dimension of the fixing screws. The structure of the ventilator is large on the rear side.
【0008】[0008]
本考案は上記した構成により、換気装置を天井面に取り付けるには、あらかじ め本体の固定孔に固定ねじを挿入して仮固定しておき、本体を天井の取付位置に 片方の手で支持し、もう片方の手でドライバーを持って、固定ねじを締めつける ことによって、本体の取り付け工事を一人で行なうことができるとともに、固定 孔が本体のフランジ部に一体に設けられ、かつその径は固定ねじの外径寸法より 前方側を小さく後方側を大きくしただけの単純なものであり、固定ねじの締めつ けによる変形もなく、しかも固定ねじの仮固定用の保持部品を別途設けることも 不要となり、その保持部品の紛失もなくなることとなる。 According to the present invention, when the ventilation device is mounted on the ceiling surface, the fixing screw is inserted into the fixing hole of the main body and temporarily fixed, and the main body is supported at the mounting position on the ceiling with one hand. Then, by holding the screwdriver with the other hand and tightening the fixing screw, the installation work of the main body can be done by one person, and the fixing hole is integrally provided in the flange part of the main body, and its diameter is fixed. It is a simple one that the front side is smaller and the rear side is larger than the outer diameter of the screw, there is no deformation due to tightening of the fixing screw, and there is no need to additionally provide a holding part for temporary fixing of the fixing screw. Therefore, the holding parts will not be lost.
