Description

【０００１】
【発明の属する技術分野】
本発明は天井用換気扇に係わり、特に天井への取付構造を改良した天井用換気扇に関する。
【０００２】
【従来の技術】
従来の、天井用換気扇の天井への取付けは、例えば、特許文献１の図２に示すように、天井用換気扇の換気扇本体枠を天井の開口縁に取付ける構造として、換気扇本体枠下端の幅広フランジに設けられた取付孔に下方よリ取付ネジを貫通させた後、野縁に螺合させて締付け固定するものがあり、また、特許文献１の図１に示すように、天井用換気扇の本体カバーである吸込みグリルを小さくしてデザイン性を向上させるには、換気扇取付用の野縁に直接上記のような方法で換気扇本体枠を取付け、その後幅広フランジを覆うように天井板を貼って、吸込みグリルで覆う面積を最小にするというように、施工の順序で対応する構造がある。
【０００３】
しかしながら、従来の天井用換気扇の取付構造は、特許文献１の図２に示す構造においては、本体カバーである吸込みグリルにより換気扇本体枠下端の幅広フランジを覆う必要があるため、吸込みグリル７が大きくなり、デザイン性が失われ、また、特許文献１の図１に示す構造において、天井板を貼った後の換気扇施工が不可能であり、施工順序に制約をうける等の問題があった。

【０００５】
【発明が解決しようとする課題】
本発明は上述した事情を考慮してなされたもので、デザイン性、施工性に優れた天井用換気扇を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するため、本発明の１つの態様によれば、下面に吸気開口、側面又は上面に排気開口が設けられ、かつ送風機が収容され、室内側より天井の開口部縁の周囲に設けられる野縁に取付けられる換気扇本体と、前記吸気開口を覆うように取付けられた本体カバーを有する天井用換気扇において、前記換気扇本体には、前記換気扇本体側面下方に複数の取付孔が設けられ、この取付孔に挿入された筒状のスペーサと、このスペーサを貫通する取付ネジを用い、前記スペーサの一端が前記取付ネジの頭部に当接し、前記スペーサの他端が前記野縁に当接するように前記取付ネジを前記野縁に螺合させることで、前記換気扇本体が前記野縁に取付けられることを特徴とする天井用換気扇が提供される。これにより、デザイン性、施工性に優れた天井用換気扇が実現される。
【０００７】
【発明の実施の形態】
以下、本発明に係わる天井用換気扇の一実施形態について添付図面を参照して説明する。
【０００８】
図１は本発明に係わる天井用換気扇の縦断面図である。
【０００９】
図１に示すように、本発明に係わる天井用換気扇１は、下面に吸気開口２、例えば側面に排気開口３が設けられた換気扇本体４と、この換気扇本体４に収容された送風機５と、吸気開口２を覆うように取付けられた本体カバー６を有している。
【００１０】
図１及び図２に示すように、換気扇本体４の側面下方に複数の取付孔７が穿設され、この取付孔７に挿入された筒状例えば円筒形状のスペーサ８を介して取付ネジ９により、換気扇本体４は、天井１０の開口部縁１１に取付けられている。
【００１１】
この換気扇本体４の取付構造は、取付孔７及びスペーサ８を貫通する取付ネジ９が、開口部縁１１と同一開口面積の開口１２ａが形成されるように開口部縁１１の周囲に設けられた野縁１２に、螺子孔を形成しながら螺合され、スペーサ８の一端８ａが取付ネジ９の頭部９ａに当接し、他端８ｂが野縁１２に当接するようになっており、換気扇本体４が野縁１２にガタつきなく取付けられている。
【００１２】
なお、図３に示すように、換気扇本体４の下端全周に幅狭例えば幅１５ｍｍのフランジ４ｆを設けることにより、天井板１０の開口寸法が大きい場合でも、換気扇本体４と野縁１２の間に生じる隙間を遮蔽でき、また、換気扇本体４を野縁１２に挿入する際、フランジ４ｆが天井板１０に突当リ、上下方向の位置、及び水平性が決まり易く施工性が向上する。
【００１３】
次に本発明に係わる天井用換気扇の取付方法について説明する。
【００１４】
図４に示すように、開口１２ａが設けられた野縁１２を、天井下地材が取付けられる前か、あるいは下地材が既に取付けられている場合には開口を明けた後天井１０に取付ける。
【００１５】
図５に示すように、野縁１２の開口１２ａから、換気扇本体４を挿入し、図６に示すように、換気扇本体４下端部と開口１２ａ下端を一致させ、スペーサ８を取付孔７に挿入し、しかる後、取付ネジ９をスペーサ８に挿入し、ドライバーにより取付ネジ９を回し、野縁１２に螺子孔を形成しながら螺合し、換気扇本体４を野縁１２に螺着し、換気扇本体４を天井１０に取付ける。さらに、吸気開口２を覆うように本体カバー６を天井１０に取付けて天井用換気扇の取付けは完了する。
【００１６】
上記取付過程において、換気扇本体４の取付孔７に挿入されたスペーサ８を貫通した取付ネジ９により、換気扇本体４が野縁１２に取付けられるため、従来必要とされるような下方からネジで取付けるための幅広いフランジを換気扇本体の下端に設ける必要がない。また、幅広いフランジがないため、取付作業は、天井板を貼る前でも、後でも容易に対応可能である。さらに、野縁寸法のバラツキが大きい場合でも、スペーサ８を介して取付ネジ９で締付けているため、換気扇本体４と野縁１２間の隙間は適切に調整され、換気扇本体４の変形が防止される。
【００１７】
なお、図７に示すように、換気扇本体４の側面下方に設けられた複数の取付孔７の上方に、仮止め用の取付ボルト９ｖ及び取付ボルト９ｖが螺合するカーリングナット９ｎを２箇所以上設けることにより、取付ボルト９ｖを手で締付けてその先端を換気扇本体４より外に突出させ、野縁１２に乗せることで、換気扇本体４を仮止めすることができ、取付ネジ９をドライバーで締付ける際に、換気扇本体４を支える必要がなく、取付作業が容易になる。また、２箇所以上の取付ボルト９ｖが野縁１２に乗ることにより、上下方向の位置が決まり、さらに施工性が向上する。
【００１８】
従って、上記のように本実施例によれば、幅広フランジが設けられていないのでこれを覆う必要がなく、本体カバーをコンパクトにすることが可能となって、デザイン性が向上し、施工順序に制約をうけず、施工性が向上する。さらに、換気扇本体の変形がなく、送風機性能が向上する。
【００１９】
また、換気扇本体を取付けるための他の取付構造について説明する。
【００２０】
図２に示す上記取付構造が取付孔に挿入されたスペーサを介して取付ネジにより行われるのに対して、本取付構造は、少なくとも１箇所は取付孔を直接貫通する取付ネジにより行われる。
【００２１】
例えば、図８に示すように、換気扇本体４Ａ側面下方には、一面に２箇所の取付孔７Ａａと、その対向面に２箇所の取付孔７Ａｂが設けられ、取付孔７Ａａを直接貫通する取付ネジ４Ａａにより、換気扇本体４Ａは天井１０Ａに設けられた野縁１２Ａに取付けられ、取付孔７Ａｂに挿入されたスペーサ８Ａを貫通する取付ネジ４Ａｂにより換気扇本体４Ａは野縁１２Ａに取付けられている。従って、換気扇本体と野縁間の隙間は適切に調整されて、換気扇本体の変形が防止されると共に、換気扇本体の一面が確実に野縁に固着され、換気扇運転時の振動が防止される。他の構成は図１に示す天井用換気扇と異ならないので、同一符号を付して説明は省略する。
【００２２】
さらに、換気扇本体を取付けるための他の取付構造について説明する。
【００２３】
図２に示す上記取付構造が換気扇本体に穿設された取付孔を用いるのに対して、本取付構造は、取付孔を内側に突出するバーリング孔を用いる。
【００２４】
例えば、図９に示すように、換気扇本体４Ｂ側面下方に設けられた複数の取付孔７Ｂは、内側に突出するバーリング孔である。従って、挿入されるスペーサ８Ａが水平に安定しやすく、そのため取付ネジ４Ｂを水平に締め易く、施工性が向上する。
【００２５】

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a ceiling ventilation fan according to the present invention will be described with reference to the accompanying drawings.
[0008]
FIG. 1 is a longitudinal sectional view of a ceiling ventilation fan according to the present invention.
[0009]
As shown in FIG. 1, a ceiling ventilation fan 1 according to the present invention includes a ventilation fan body 4 having an intake opening 2 on the lower surface, for example, an exhaust opening 3 on a side surface, and a blower 5 housed in the ventilation fan body 4. A main body cover 6 is attached so as to cover the intake opening 2.
[0010]
As shown in FIGS. 1 and 2, a plurality of mounting holes 7 are formed in the lower side of the side surface of the ventilation fan body 4, and the mounting screws 9 are inserted through cylindrical, for example, cylindrical spacers 8 inserted into the mounting holes 7. The ventilation fan body 4 is attached to the opening edge 11 of the ceiling 10 .
[0011]
In the attachment structure of the ventilation fan body 4, the attachment screw 9 that penetrates the attachment hole 7 and the spacer 8 is provided around the opening edge 11 so that the opening 12 a having the same opening area as the opening edge 11 is formed. A screw hole is formed in the field edge 12, and a screw hole is formed. One end 8a of the spacer 8 is in contact with the head 9a of the mounting screw 9, and the other end 8b is in contact with the field edge 12. 4 is attached to the field edge 12 without backlash.
[0012]
As shown in FIG. 3, by providing a flange 4 f having a narrow width, for example, 15 mm, around the entire lower end of the ventilation fan body 4, even when the opening size of the ceiling panel 10 is large, the ventilation fan body 4 and the field edge 12 are not connected. Further, when the ventilation fan body 4 is inserted into the field edge 12, the flange 4f abuts against the ceiling plate 10, the vertical position and horizontality are easily determined, and the workability is improved.
[0013]
Next, a method for mounting the ceiling ventilation fan according to the present invention will be described.
[0014]
As shown in FIG. 4, the field edge 12 provided with the opening 12 a is attached to the ceiling 10 before the ceiling base material is attached, or after the opening is opened when the base material is already attached.
[0015]
As shown in FIG. 5, the ventilation fan body 4 is inserted from the opening 12a of the field edge 12, and as shown in FIG. 6, the lower end of the ventilation fan body 4 and the lower end of the opening 12a are aligned, and the spacer 8 is inserted into the mounting hole 7. After that, the mounting screw 9 is inserted into the spacer 8, the mounting screw 9 is turned by a screwdriver, screwed while forming a screw hole in the field edge 12, and the ventilation fan body 4 is screwed to the field edge 12. The main body 4 is attached to the ceiling 10. Furthermore, the main body cover 6 is attached to the ceiling 10 so as to cover the intake opening 2, and the installation of the ceiling ventilation fan is completed.
[0016]
In the above attachment process, the ventilation fan body 4 is attached to the field edge 12 by the attachment screw 9 penetrating the spacer 8 inserted into the attachment hole 7 of the ventilation fan body 4, so that it is attached from below with a screw as conventionally required. There is no need to provide a wide flange for the lower end of the ventilation fan body. In addition, since there is no wide flange, the mounting operation can be easily performed before or after the ceiling plate is pasted. Furthermore, even when the variation in the field edge size is large, the gap between the ventilation fan body 4 and the field edge 12 is appropriately adjusted and the deformation of the ventilation fan body 4 is prevented because the mounting screws 9 are tightened through the spacer 8. The
[0017]
In addition, as shown in FIG. 7, the fixing bolt 9v for temporary fixing and the curling nut 9n to which the mounting bolt 9v is screwed are provided at two or more places above the plurality of mounting holes 7 provided on the lower side of the side surface of the ventilation fan body 4. By providing, the mounting bolt 9v is tightened by hand and the tip of the mounting bolt 9v protrudes from the ventilation fan body 4 and is placed on the edge 12, so that the ventilation fan body 4 can be temporarily fixed, and the mounting screw 9 is tightened with a screwdriver. At this time, it is not necessary to support the ventilation fan body 4, and the mounting work is facilitated. Moreover, when two or more mounting bolts 9v ride on the field edge 12, the position in the vertical direction is determined, and the workability is further improved.
[0018]
Therefore, according to the present embodiment as described above, since the wide flange is not provided, it is not necessary to cover this, and the main body cover can be made compact, the design is improved, and the construction sequence is improved. Workability is improved without any restrictions. Furthermore, there is no deformation | transformation of a ventilation fan main body, and fan performance improves.
[0019]
Moreover, the other attachment structure for attaching a ventilation fan main body is demonstrated.
[0020]
The mounting structure shown in FIG. 2 is performed by a mounting screw through a spacer inserted into the mounting hole, whereas this mounting structure is performed by a mounting screw that directly passes through the mounting hole.
[0021]
For example, as shown in FIG. 8, two mounting holes 7Aa are provided on one side below the side surface of the ventilation fan body 4A, and two mounting holes 7Ab are provided on the opposite surface, and mounting screws that directly penetrate the mounting holes 7Aa. The ventilation fan body 4A is attached to a field edge 12A provided on the ceiling 10A by 4Aa, and the ventilation fan body 4A is attached to the field edge 12A by a mounting screw 4Ab penetrating the spacer 8A inserted into the attachment hole 7Ab. Therefore, the gap between the ventilation fan body and the field edge is adjusted appropriately to prevent deformation of the ventilation fan body, and one surface of the ventilation fan body is securely fixed to the field edge, and vibration during operation of the ventilation fan is prevented. Since the other configuration is not different from the ceiling fan shown in FIG. 1, the same reference numerals are given and description thereof is omitted.
[0022]
Furthermore, another mounting structure for mounting the ventilation fan body will be described.
[0023]
The mounting structure shown in FIG. 2 uses a mounting hole formed in the ventilation fan body, whereas this mounting structure uses a burring hole that protrudes inward.
[0024]
For example, as shown in FIG. 9, the plurality of attachment holes 7B provided on the lower side of the side surface of the ventilation fan body 4B are burring holes protruding inward. Therefore, the spacer 8A to be inserted is easy to stabilize horizontally, so that the mounting screw 4B can be easily tightened horizontally, and workability is improved.
