Description

ダクト用換気扇Duct ventilation fan
　本発明は、ダクトを通じて外気を室内に給気する、あるいはダクトを通じて室内空気を室外に排気するダクト用換気扇に関するものである。 The present invention relates to a duct ventilation fan which supplies outside air to a room through a duct or exhausts room air outside through a duct.
　まず、ダクト用換気扇の施工について説明する。住宅の施工では、天井内に換気用のダクトをあらかじめ配管した後、天井材等の敷設をし、その後天井に設けた換気扇取付用の開口にダクト用換気扇を設置することが多い。このため、ダクト用換気扇のダクト接続部と換気扇本体とを係脱自在にし、まず天井内に配管したダクトとダクト接続部とを接続し、ダクト接続部を天井に仮固定した後、換気扇本体をダクト接続部に沿って据付ける方法が多く採用されている。この据付方法を実現するため、換気扇本体の天板の両端部分に突出した突起を設け、ダクト接続部の上端に、この突起と係合する係合穴を設けた換気扇が開示されている（例えば、特許文献１）。 First, construction of the duct ventilation fan will be described. In the construction of a house, a duct for ventilation is piped in advance in a ceiling, and then a ceiling material or the like is laid, and then a duct ventilation fan is often installed in an opening for ventilating fan attachment provided on the ceiling. For this reason, the duct connection part of the duct ventilation fan and the ventilation fan main body are made engageable / detachable, first the duct piped in the ceiling and the duct connection part are connected, and the duct connection part is temporarily fixed to the ceiling. Many methods of installation along duct connections are employed. In order to realize this installation method, there is disclosed a ventilating fan provided with protrusions projecting on both ends of the top plate of the ventilating fan main body, and an engagement hole engaging with the protrusion at the upper end of the duct connection portion (for example, , Patent Document 1).
　また、ダクト接続部と換気扇本体の風漏れを防止するため、または止水性を高めるため、換気扇本体の突起がダクト接続部の係合穴に係合するより先に、換気扇本体下部側にてダクト接続部と換気扇本体とが係合する形状とし、施工性を改善した構成が開示されたものがある（例えば、特許文献２）。 Also, in order to prevent wind leakage of the duct connection portion and the ventilating fan main body or to enhance the water barrier property, the duct of the lower portion of the ventilating fan main body before the protrusion of the ventilating fan main body engages with the engagement hole of the duct connecting portion. There has been disclosed a configuration in which the connection portion and the ventilating fan main body are engaged to improve the workability (for example, Patent Document 2).

　特許文献１に開示されたダクト用換気扇では、換気扇本体をダクト接続部に沿ってスライドさせながら天井の開口部に挿入した際、ダクト接続部の係合穴を目視することが困難という課題があった。また、ダクト接続部の係合穴を目視しにくいことから、ダクト接続部の係合穴と換気扇本体の突起とを係合できないという課題があった。また、ダクト接続部が換気扇本体に対し外側（ダクト側）に倒れると、ボディの天面の突起とダクト接続部の係合穴とが掛り合わず、固定できないといった問題があった。さらには、ダクト接続部が外れたまま換気扇本体を固定することで、換気扇本体とダクト接続部との間に隙間が生じ、空気等が漏れるなどの課題があった。 In the duct ventilation fan disclosed in Patent Document 1, there is a problem that it is difficult to visually check the engagement hole of the duct connection portion when the ventilation fan main body is inserted into the opening of the ceiling while sliding along the duct connection portion. The In addition, since it is difficult to visually check the engagement hole of the duct connection portion, there is a problem that the engagement hole of the duct connection portion can not be engaged with the projection of the ventilating fan main body. In addition, when the duct connection portion falls to the outside (duct side) with respect to the ventilating fan main body, there is a problem that the projection on the top surface of the body and the engagement hole of the duct connection portion do not engage and can not be fixed. Furthermore, by fixing the ventilating fan main body while the duct connecting portion is detached, a gap is generated between the ventilating fan main body and the duct connecting portion, and there is a problem that air or the like leaks.
　特許文献２では、換気扇本体とダクト接続部の下縁部とで固定することで気密性及び止水性について改善されたものが開示されているが、取付構造が複雑になるなどの課題があった。また、換気扇本体隙間板を必要とするなど部品点数が多く、作業時の手間が増えるなどの課題があった。さらには、換気扇本体下部側にてダクト接続部と換気扇本体とが係合う形状を備えたことで、換気扇本体の風路が小さくなり送風性能に影響を与えたり、騒音が大きくなったりするといった課題もあった。 Patent Document 2 discloses that the air tightness and waterproofness are improved by fixing at the ventilation fan main body and the lower edge portion of the duct connection portion, but there is a problem such as the mounting structure becomes complicated. . In addition, the number of parts required is large, for example, requiring the ventilation fan main body clearance plate, and there is a problem such as an increase in time and labor during operation. Furthermore, by providing the duct connecting portion and the ventilating fan body to be engaged on the lower side of the ventilating fan body, the air path of the ventilating fan body becomes smaller, which affects the air blowing performance and noise increases. There was also.
　本発明は、係る従来の問題点を解決するためになされたものであって、容易にかつ確実にダクト接続部を換気扇本体に固定することが可能で、さらには送風性能に影響を与えないダクト用換気扇を得ることである。 The present invention has been made to solve such conventional problems, and it is possible to easily and reliably fix a duct connection portion to a ventilation fan main body, and further, a duct which does not affect the air blowing performance. It is to obtain a ventilation fan.
　上記課題を解決するために本発明は、給気口が下面に設けられ、排気口が側面に設けられ、上方へ突出する突起が天面に設けられた換気扇本体と、換気扇本体の側面に着脱可能に取り付けられ、排気口を延長する筒状の吐出口部を備えたダクト接続部とを有する。ダクト接続部は、突起と係合する係合穴が設けられた上面部と、上面部から下方へ突出して係合穴に係合した突起を囲う囲い込み枠とを備える。 In order to solve the above problems, according to the present invention, a ventilating fan main body provided with an air supply port on the lower surface, an exhaust port on the side surface, and a projection projecting upward is provided on the top surface And a duct connection with a tubular outlet which is mounted and extends the outlet. The duct connection portion includes an upper surface portion provided with an engagement hole engaged with the projection, and an enclosure frame which protrudes downward from the upper surface portion and surrounds the projection engaged with the engagement hole.
　本発明によれば、換気扇施工時にダクト接続部に設けられた囲い込み枠に、換気扇本体天面の突起が確実に納まることが可能で、さらには突起と係合穴との位置合わせが容易で係合しやすくなるものである。また、換気扇本体施工時に、ダクト接続部が換気扇本体から外れるといった不具合、及びダクト接続部が換気扇本体から外れたために生じる風漏れといった不具合を改善できる。 According to the present invention, the protrusion of the top surface of the ventilating fan main body can be reliably accommodated in the enclosure frame provided at the duct connection portion at the time of installation of the ventilating fan, and furthermore, the alignment between the protrusion and the engagement hole is easy and engaging It is easy to match. In addition, at the time of installation of the ventilating fan main body, it is possible to improve problems such as the duct connecting portion being detached from the ventilating fan main body, and problems such as air leakage caused by the duct connecting portion being detached from the ventilating fan main body.

　（ダクト用換気扇）
　実施の形態１に係るダクト用換気扇について説明する。ボディ２は、一面を開口した箱型で、箱開口とは逆の面（天面側）に、換気する空気を流通させる換気駆動体である多翼式送風機１と、多翼式送風機１を収納するファンケーシング５とを有している。ファンケーシング５は、下面が開放されて吸込口６が形成されている。多翼式送風機１は、モータ３と、モータ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。 (Ventilation fan for duct)
The duct ventilation fan according to the first embodiment will be described. The body 2 is a box type having one side open, and a multi-wing fan 1 which is a ventilation drive body for circulating air to be ventilated on the side (top side) opposite to the box opening, and a multi-wing fan 1 And a fan casing 5 for housing. The lower surface of the fan casing 5 is opened to form the suction port 6. The multi-blade fan 1 is composed of a motor 3 and a fan 4 inserted and coupled to a drive shaft of the motor 3.
　（ダクト用換気扇内部の説明）
　ファンケーシング５には容易に開閉可能な端子カバー１１が備え付けられている。また、端子カバー１１内には外部電源電線を接続可能な電線接続装置２０を備えている。電線接続装置２０とモータ３とは、器内電線により電気的に接続されている。外部電源電線（図示しない）より印加された電気が電線接続装置２０を介し器内電線からモータ３に流れることで電気エネルギーをモータ３の回転運動に変換する。モータ３の回転運動は、駆動軸に連結したファン４に伝えることでファン４が回転し、空気の流れを形成する。ファンケーシング５により、吸込口６より吸われた空気は、多翼式送風機１によってファンケーシング５の内壁に沿って排気口２ｂに至る排気風路を形成している。 (Description of the inside of the ventilation fan for the duct)
The fan casing 5 is provided with a terminal cover 11 which can be easily opened and closed. Further, in the terminal cover 11, a wire connecting device 20 capable of connecting an external power supply wire is provided. The wire connection device 20 and the motor 3 are electrically connected by the inner wire. Electric energy is converted into rotational motion of the motor 3 by the flow of electricity applied from an external power supply wire (not shown) from the in-unit wire to the motor 3 through the wire connection device 20. The rotational movement of the motor 3 is transmitted to the fan 4 connected to the drive shaft to rotate the fan 4 to form an air flow. With the fan casing 5, the air sucked from the suction port 6 forms an exhaust air passage extending along the inner wall of the fan casing 5 and the exhaust port 2 b by the multiblade fan 1.
　（化粧グリル）
　ダクト用換気扇１００は、ファンケーシング５などの内部部品が見えると見栄えが悪いため、内部部品を見えないようにするための意匠部品である化粧グリル１２を備える。化粧グリル１２は、換気扇本体への取付用のスプリング１３を備えており、スプリング１３をファンケーシング５に備えられている化粧グリル取付用スプリング固定部７に引掛けることにより固定する。化粧グリル１２は、スプリング１３で取り付けられることで、天井面３２の厚さが多少変動しても容易に対応可能で、天井面３２との隙間などが生じないようしている。化粧グリル１２は、ダクト用換気扇１００の意匠性の向上の他にも多翼式送風機１への異物混入の防止の効果もある。 (Cosmetic grill)
The duct ventilation fan 100 has a cosmetic grille 12 which is a design component for making the internal parts invisible so that the internal appearance such as the fan casing 5 looks bad when the internal parts such as the fan casing 5 are visible. The cosmetic grill 12 is provided with a spring 13 for attachment to the ventilating fan main body, and is fixed by hooking the spring 13 on a cosmetic grill attachment spring fixing portion 7 provided on the fan casing 5. The cosmetic grille 12 is attached by the spring 13 so that it can be easily coped with even if the thickness of the ceiling surface 32 changes a little, and a gap with the ceiling surface 32 or the like is not generated. In addition to the improvement of the design of the ventilation fan 100 for a duct, the makeup grille 12 also has the effect of preventing foreign matter mixing into the multi-blade fan 1.
　（ダクト接続部）

The duct ventilation fan 100 is attached to the body 2 and a side surface of the body 2 and has a duct connection including a discharge port 10 extending to a position extending perpendicularly from the side surface of the body 2 and communicating the exhaust port 2b with the duct 14 And 8. The discharge port portion 10 is formed in a step shape with different diameters. This is stepped in consideration of the fact that the duct 14 to be piped can cope with different diameters and the workability such as taping. The duct 14 extends to the outside, and is connected to a hood or the like provided on the outside wall of the building to form a ventilating air path for ventilating the air in the house.
　（シャッター）
　ダクト接続部８内には、風圧にて開閉するシャッター９が設けられている。シャッター９は、ダクト用換気扇１００の運転時には風圧で開き、停止時はシャッター９の自重でダクト接続部８の内部を閉鎖する。このようにシャッター９を設けることで、ダクト用換気扇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。本説明では風圧で開閉するシャッター９について説明したが、電気式で駆動するものも使用される場合がある。 (shutter)
In the duct connection portion 8, a shutter 9 which is opened and closed by wind pressure is provided. The shutter 9 is opened by wind pressure when the duct ventilation fan 100 is in operation, and shuts down the inside of the duct connection portion 8 by its own weight when stopped.

In the temporarily fixed state, the body 2 and the duct connection portion 8 engage with the engagement holes 22 provided in the upper surface portion 33 of the duct connection portion 8 with the protrusion 21 projecting upward from the top surface of the body 2. Further, the protrusion 8 b provided on the flange portion 8 a of the duct connection portion 8 is inserted into the square hole 2 c of the flange portion 2 a of the body 2. In this manner, horizontal movement of the body 2 and the duct connection portion 8 is suppressed and fixed. In addition, when the duct connection portion fixing projection 23 on the side surface on the exhaust port 2b side of the body 2 is fitted into the angular groove 24 of the duct connection portion 8, movement in the vertical direction is suppressed and fixed. In this manner, the body 2 and the duct connection portion 8 are fixed, the exhaust port 2b of the body 2 and the discharge port portion 10 of the duct connection portion 8 communicate with each other, and the air to be ventilated can be exhausted through the duct 14. .
　（換気扇本体とダクト接続部の取り外し方）
　ボディ２とダクト接続部８とを取り外す場合は、図８に示すように、ボディ２の排気口２ｂ側の側面のダクト接続部取り外し用突起２５をボディ２の内側に引くことによりダクト接続部固定突起２３が角溝２４から外れ、垂直方向への移動が可能となりスライドして取り外しが可能となる。 (How to remove the ventilation fan body and the duct connection)

The projection 23 is disengaged from the angular groove 24 and can be moved in the vertical direction to slide and be removed.
　（従来の問題点の説明）
　前述したボディ２とダクト接続部８との取り付け方について、図５を用いて従来の問題点を説明する。ダクト接続部８を天井面３２（または壁面）の埋込穴２６に仮固定後、ボディ２を埋込穴２６に挿入する場合、図５（従来例）に示すようにダクト接続部８がダクト用換気扇１００に対し外側（ダクト１４側）に倒れると、ボディ２の天面の突起２１とダクト接続部８の係合穴２２とが係合せず、天面側で固定できないといった問題があった。特に、風漏れを防止するためボディ２のダクト接続部８との圧接面２７と連続した面の上部に備えた突起２８と、突起２８を囲い込むダクト接続部８に設けた囲い込み枠２９とのような係合では固定しづらいことがあった。 (Description of conventional problems)
About the method of attaching the body 2 and the duct connection part 8 which were mentioned above, the conventional problem is demonstrated using FIG. When temporarily inserting the body 2 into the embedding hole 26 after temporarily fixing the duct connecting part 8 in the embedding hole 26 of the ceiling surface 32 (or the wall surface), as shown in FIG. 5 (conventional example) When it falls down outside (the duct 14 side) with respect to the ventilation fan 100, there is a problem that the projection 21 on the top surface of the body 2 and the engagement hole 22 of the duct connection portion 8 do not engage and can not be fixed on the top surface side . In particular, in order to prevent wind leakage, a protrusion 28 provided on the top of a surface continuous with the pressure contact surface 27 with the duct connection portion 8 of the body 2 and an enclosing frame 29 provided on the duct connection portion 8 enclosing the protrusion 28. In such engagement, it was difficult to fix.
　（本願発明の説明）
　本実施の形態では、図６及び図７に示すように、ダクト接続部８の係合穴２２と連接しボディ２の突起２１側に向けて上面部３３から突出した囲い込み枠２９，３０を備えている。ダクト接続部８は、係合穴２２が形成された上面部３３及び囲い込み枠２９，３０を一体で形成しており、部品精度のばらつきを少なくしている。囲い込み枠２９，３０は、突起２１の前方（ダクト接続部８側）を囲い込み枠２９が囲い、突起２１の後方（ダクト用換気扇１００のモータ３側）を囲い込み枠３０が囲うことで、突起２１と係合穴２２との位置合わせを容易としている。また、囲い込み枠２９，３０は、突起２１側に突出して備えていることから、ボディ２の挿入時に早い段階で突起２１を枠内に迎え入れ導くことが可能で、施工時に目視できない部分ながら容易に位置合わせができる構造としている。 Description of the Invention
In the present embodiment, as shown in FIG. 6 and FIG. 7, enclosure frames 29 and 30 connected to the engagement hole 22 of the duct connection portion 8 and projecting from the upper surface portion 33 toward the projection 21 side of the body 2 are provided. ing. The duct connection portion 8 integrally forms the upper surface portion 33 in which the engagement hole 22 is formed and the enclosing frames 29 and 30, thereby reducing variation in component accuracy. With the enclosure frames 29 and 30, the enclosure frame 29 encloses the front (the duct connection portion 8 side) of the projection 21 and the enclosure frame 30 surrounds the rear (the motor 3 side of the duct ventilation fan 100) of the projection 21. And the engagement hole 22 are easy to align. In addition, since the enclosure frames 29 and 30 are provided so as to project toward the projection 21 side, the projection 21 can be received and guided into the frame at an early stage when the body 2 is inserted. It has a structure that allows alignment.
　さらに、囲い込み枠３０の下部（突起２１側）は、枠の縁から係合穴２２に向けてなだらかに傾斜する傾斜部３０ｂを設けている。囲い込み枠３０に、係合穴２２のボディ２と対面する側の縁部２２ａから囲い込み枠３０の先端３０ａにかけて傾斜する傾斜部３０ｂを設けることにより、傾斜部３０ｂに沿って突起２１を係合穴２２に確実に導くことが可能としている。このようにすることで、ダクト接続部８がダクト１４側に倒れた場合でも、突起２１側に突出した囲い込み枠２９，３０と、さらに囲い込み枠３０に備えた傾斜部３０ｂとでボディ２の挿入時の早い段階で突起２１を迎えることが可能で、突起２１を確実に導くことができ、突起２１と係合穴２２とが容易に係合することができる。 Furthermore, the lower part (protrusion 21 side) of the enclosure frame 30 is provided with the inclined part 30b which inclines gently toward the engagement hole 22 from the edge of a frame. By providing the enclosure frame 30 with the inclined portion 30b which inclines from the edge 22a on the side facing the body 2 of the engagement hole 22 to the tip 30a of the enclosure frame 30, the projection 21 is engaged with the engagement hole along the inclined portion 30b. It is possible to lead to 22 surely. By doing this, even when the duct connection portion 8 falls to the duct 14 side, the insertion of the body 2 is performed by the enclosure frames 29 and 30 projecting to the projection 21 side and the inclined portion 30 b further provided to the enclosure frame 30. The projections 21 can be received at an early stage of time, and the projections 21 can be reliably guided, and the projections 21 and the engagement holes 22 can be easily engaged.
　突起２１は、係合穴２２と嵌りあう箇所から先端２１ａに向けて徐々に細くなるよう傾斜して形成している。このようにすることで、ダクト接続部８が多少傾いても、突起２１の先端２１ａと囲い込み枠２９，３０との間に余裕があることから、突起２１は容易に囲い込み枠２９，３０の間に入り、係合穴２２に導かれるようになっている。また、さらに突起２１の先端２１ａは、面取りを施して面取り部３１を設けている。面取り部３１を設けることで、さらに突起２１は囲い込み枠３０に設けた傾斜部３０ｂと沿いやすくなり、より係合しやすい構造としている。 The protrusion 21 is formed to be inclined so as to be gradually narrowed toward the tip 21 a from a place where it fits into the engagement hole 22. By doing this, even if the duct connection portion 8 is slightly inclined, there is a margin between the tip 21 a of the projection 21 and the enclosing frame 29, 30, so the projection 21 can be easily between the enclosing frames 29, 30. , And led to the engagement hole 22. Further, the end 21 a of the projection 21 is chamfered to provide a chamfered portion 31. By providing the chamfered portion 31, the projection 21 can be easily aligned with the inclined portion 30 b provided on the enclosure frame 30, and can be engaged more easily.
　上記のように、ダクト用換気扇１００の施工時にダクト接続部８に設けられた囲い込み枠２９，３０に、ボディ２の天面の突起２１が確実に納まることが可能で、さらには突起２１と係合穴２２との位置合わせが容易で係合しやすくなるものである。また、ダクト接続部８がボディ２から外れるといった不具合、及びダクト接続部８が換気扇本体から外れたために生じる風漏れといった不具合を改善できる。 As described above, the projections 21 on the top surface of the body 2 can be reliably accommodated in the enclosure frames 29 and 30 provided in the duct connection portion 8 at the time of construction of the duct ventilation fan 100, and further, they are engaged with the projections 21. The alignment with the mating hole 22 is easy and easy to engage. In addition, it is possible to improve the problem that the duct connection portion 8 is detached from the body 2 and the problem such as the air leakage caused by the duct connection portion 8 being detached from the ventilation fan main body.
