実開昭６３−５５０４０号公報Japanese Utility Model Publication No. 63-55040 実開昭６０−１２１１９号公報Japanese Utility Model Publication No. 60-12119 実開昭５９−１９５４３４号公報Japanese Utility Model Publication No.59-195434 特開２００４−１４４３３１号公報JP 2004-144331 A

この種の従来の換気装置は、送風機が多翼式のものと軸流式のものとがある。多翼式のものでは、嵩張るスクロールケーシングがあり、羽根車を駆動するモーターは、本体に固定されるスクロールケーシングに取付けられている。しかし、大風量・低静圧のプロペラファンを使った軸流式では、風洞がファンケーシングともなるので、プロペラファンを駆動するモーターを含め送風機は、屋外フードないしは、換気口に取付けた枠に設けた取付脚に取付けられている。従って、防雨防風のための屋外フード又はそれに類する構造は、換気装置の本体構造であり、通気開口部等に極普通に取付けられる屋外フードと共通化することはできず、外観意匠のまとまった屋外フードで換気装置を構成することができなかった。また、施工についても、屋外フード又はそれに類する構造とともに送風機を取付けなくてはならず、扱いが面倒で施工性及びメンテナンス性があまりよくないものであった。   This type of conventional ventilator is classified into a multi-blade type and an axial flow type. The multi-blade type has a bulky scroll casing, and a motor for driving the impeller is attached to a scroll casing fixed to the main body. However, in the axial flow type using a propeller fan with a large air volume and low static pressure, the wind tunnel also serves as a fan casing. It is attached to the mounting leg. Therefore, the outdoor hood for rain and wind protection or a similar structure is the main body structure of the ventilation device, and cannot be shared with the outdoor hood that is normally attached to the ventilation opening, etc. Ventilator could not be configured with outdoor hood. In addition, with regard to the construction, it was necessary to attach an air blower together with an outdoor hood or a similar structure, and the handling was troublesome and the workability and maintainability were not so good.

本発明は、上記した問題点を解決するためになされたものであり、その課題とするところは、屋外側の外観意匠のまとまりの可能な、施工性及びメンテナンス性の良い軸流式の送風機による換気装置を得ることであり、その性能の向上を図ることである。   The present invention has been made in order to solve the above-described problems, and the problem is that the outdoor-side appearance design can be organized by an axial-flow blower with good workability and maintainability. It is to obtain a ventilator and to improve its performance.

上記課題を解決するために本発明は、室内外を連通させるパイプやダクト等に屋外側から挿入して装着する円筒状の風洞を有し、風洞内でプロペラ式の羽根車が回転し、羽根車を駆動するモーターが風洞の屋外側開口部の外側に取付ネジでネジ付けされた送風機を備えた本体に、風洞の屋外側開口部の外周に連設され、平面部を有する半径方向に張出すフランジ部と、このフランジ部の端縁に設けられ、屋外側の壁面に当接する当接部を有する前面構造を設ける。本体の前面構造の外側を、モーターとともに間隔をもって被覆する着脱可能の屋外フードを設ける。屋外フードを取外すことにより、送風機の本体への脱着を可能にする手段を採用する。   In order to solve the above-mentioned problems, the present invention has a cylindrical wind tunnel that is inserted into a pipe or duct that communicates indoors and outdoors from the outside, and a propeller-type impeller rotates in the wind tunnel. A motor that drives the car is connected to the outer periphery of the outdoor side opening of the wind tunnel in a body with a blower screwed to the outside of the outdoor side opening of the wind tunnel with a mounting screw. A front surface structure having a flange portion to be brought out and an abutting portion which is provided at an end edge of the flange portion and abuts against an outdoor wall surface is provided. A removable outdoor hood that covers the outside of the front structure of the main body with a motor at intervals is provided. By removing the outdoor hood, a means that enables the fan to be attached to and detached from the main body is adopted.

本発明によれば、送風機は本体から屋外フードを取外せば脱着することができ、風洞はパイプやダクト等に屋外側から挿入して装着されるものであるので、施工が容易であり、メンテナンスもし易い。そして、屋外フードは単独の構成で、本体に対して着脱可能なため、通気開口部等に極普通に取付けられる屋外フードとも共通化することができ、外観意匠のまとまりの良い換気装置が得られる。   According to the present invention, the blower can be detached by removing the outdoor hood from the main body, and since the wind tunnel is inserted and attached to the pipe, duct, etc. from the outdoor side, the construction is easy and maintenance is performed. If easy. And since the outdoor hood has a single configuration and can be attached to and detached from the main body, it can be shared with an outdoor hood that is normally attached to a ventilation opening or the like, and a ventilation device with a good appearance design can be obtained. .

本発明の換気装置は排気により換気をするもので、室内外を連通させるパイプやダクト等に屋外側から挿入して装着する円筒状の風洞を有し、風洞内でプロペラ式の羽根車が回転し、羽根車を駆動するモーターが風洞の屋外側開口部の外側に取付ネジでネジ付けされた送風機を備えた本体と、本体の屋外側を通風可能に覆う屋外フードとから構成されている。風洞の屋外側開口部の外周には、平面部を有する半径方向に張出すフランジ部と、このフランジ部の端縁に設けられ、屋外側の壁面に当接する当接部を有する前面構造が合成樹脂で風洞と一体に形成されている。風洞の屋外側開口部からフランジ部に続く部分はＲ形状のベルマウスとなっている。送風機は、風洞の屋外側開口部の口縁に中心線方向外側に延出された周方向に間隔をおいて三本形成された取付脚に、モーターの外殻のフランジにおいて取付ネジでネジ締めされて取付けられている。屋外フードは、アルミニウム材等の金属材で構成され、本体のフランジ部にネジ付けされ、本体の前面構造の外側を、モーターとともに間隔をもって被覆する。屋外フードの下部は屋外換気口として下向きに開放している。   The ventilator of the present invention ventilates by exhaust, and has a cylindrical wind tunnel that is inserted into a pipe or duct that communicates indoors and outdoors from the outside, and the propeller impeller rotates in the wind tunnel. And the motor which drives an impeller is comprised from the main body provided with the air blower screwed in the outer side of the outdoor side opening part of a wind tunnel with the installation screw, and the outdoor hood which covers the outdoor side of a main body so that ventilation is possible. On the outer periphery of the outdoor side opening of the wind tunnel, a flange structure that has a flat surface and a flange that projects in the radial direction, and a front structure that has an abutting part that is provided at the edge of the flange and abuts against the wall surface on the outdoor side are synthesized It is made of resin and integrated with the wind tunnel. The portion following the flange portion from the outdoor side opening of the wind tunnel is an R-shaped bell mouth. The blower is screwed with mounting screws at the flange of the outer shell of the motor on three circumferentially spaced mounting legs that extend outward in the centerline direction at the mouth edge of the outdoor side opening of the wind tunnel. Has been installed. The outdoor hood is made of a metal material such as an aluminum material, and is screwed to a flange portion of the main body, and covers the outside of the front structure of the main body with a motor at intervals. The lower part of the outdoor hood is open downward as an outdoor vent.

この換気装置においては、送風機は、室内外を連通させるパイプやダクト等に屋外側から挿入して装着した本体から、屋外フードを取外せば脱着することができ、施工は容易で、メンテナンスもし易い。そして、屋外フードは、送風機の取付けやその他の機能部材を持たない単独の構成であり、本体に対して着脱可能なため、通気開口部等に極普通に取付けられる屋外フードとも色調、意匠、デザイン等の共通化・標準化を実現でき、住居において外観意匠のまとまりの良い換気装置となる。   In this ventilator, the blower can be removed by removing the outdoor hood from the main body that is inserted and attached to the pipe or duct that communicates indoors and outdoors from the outdoor side, and the construction is easy and easy to maintain. . And since the outdoor hood is a single structure that does not have a blower or other functional members and can be attached to and detached from the main body, it is the same color tone, design, and design as the outdoor hood that is normally attached to the ventilation opening etc. Etc. can be realized, and it becomes a ventilation device with a good appearance design in the house.

実施の形態１．
図１は、本実施の形態の換気装置を施工状態で示す横断面図、図２は、同じく換気装置の正面図、図３は、施工途中の換気装置を示す斜視図である。 Embodiment 1 FIG.
FIG. 1 is a cross-sectional view showing the ventilation device of the present embodiment in a construction state, FIG. 2 is a front view of the ventilation device, and FIG. 3 is a perspective view showing the ventilation device in the middle of construction.

本実施の形態は、室内外を連通させるパイプ１やダクト等に屋外側から挿入して装着し、排気により換気を果たす換気装置に関するものである。この換気装置は、パイプ１等に挿入する円筒状の風洞２を有する合成樹脂製の本体フレーム３に、３枚羽根のプロペラ式の羽根車４とモーター５よりなる送風機が組付けられた本体６と、金属製の屋外フード７とから構成されている。本体フレーム３における風洞２の屋外側開口部８の外周には、平面部を有する半径方向に張出すフランジ部９と、このフランジ部９の端縁に設けられ、屋外側の壁面に当接する当接部１０を有する前面構造１１が風洞２に一体に形成されている。   The present embodiment relates to a ventilator that is inserted and installed from the outdoor side into a pipe 1 or duct that communicates indoors and outdoors, and performs ventilation by exhaust. This ventilator has a main body 6 in which a blower comprising a three-blade propeller impeller 4 and a motor 5 is assembled to a synthetic resin main body frame 3 having a cylindrical wind tunnel 2 inserted into a pipe 1 or the like. And an outdoor hood 7 made of metal. On the outer periphery of the outdoor-side opening 8 of the wind tunnel 2 in the main body frame 3, a flange portion 9 that has a flat surface and projects in the radial direction, and is provided at an edge of the flange portion 9 and abuts against the wall surface on the outdoor side. A front structure 11 having a contact portion 10 is formed integrally with the wind tunnel 2.

前面構造１１の当接部１０の外縁は、コーキングフランジとして構成され、壁面間にコーキング１２が施されたり、壁面仕上げのモルタル等で塗込まれたりする。前面構造１１の下縁には、壁面から漸次離反する水切り部１３が斜め前方に向かって成形され、滴下する雨水で壁面が汚れるのを防いでいる。水切り部１３の両側は、三角形の側面構造１４で閉塞され、水切り部１３の強度保持と、外風の側方からの吹込みを防止している。風洞２の屋外側開口部８からフランジ部９に続く部分はＲ形状のベルマウスとなっていて、風洞２の室内側開口端もＲ形状になっている。風洞２の厚みは２．５ｍｍ程度であるが、室内側開口端をＲ１．５程の丸みを持つ形状にすることにより、パイプ１との段差による圧力損失を極小さくすることができる。   The outer edge of the abutting portion 10 of the front structure 11 is configured as a caulking flange, and the caulking 12 is applied between the wall surfaces or is applied with mortar or the like for wall surface finishing. A draining portion 13 that gradually separates from the wall surface is formed on the lower edge of the front structure 11 diagonally forward to prevent the wall surface from being soiled by dripping rainwater. Both sides of the draining portion 13 are closed by a triangular side structure 14 to prevent the strength of the draining portion 13 from being maintained and blowing from the side of the outside wind. The portion following the flange portion 9 from the outdoor side opening 8 of the wind tunnel 2 is an R-shaped bell mouth, and the indoor side opening end of the wind tunnel 2 is also R-shaped. Although the thickness of the wind tunnel 2 is about 2.5 mm, the pressure loss due to the step with the pipe 1 can be minimized by making the indoor opening end round with a radius of about R1.5.

送風機は、風洞２の屋外側開口部８の口縁に中心線方向外側に延出された周方向に１２０度の間隔をおいて三本形成された取付脚１５に、モーター５が取付ネジ１６でネジ締めされて取付けられていて、送風機の軸方向寸法の吸込み側が略１／２だけ風洞２内に配置されている（図１，３参照）。各取付脚１５の自由端側には、風洞２の中心線方向に延び出す取付部１７が形成され、この取付部１７にモーター５の外殻のフランジがネジ付けされている。この取付ネジ１６を外せば、送風機は羽根車４ごと本体フレーム３から取付脚１５に羽根が干渉することなく取外すことができる。本体６は、風洞２の外周に設けられた取付バネ（図示しない）のバネ力でパイプ１に抜き差し可能に保持されるが、フランジ部９において壁面にネジ締め固定することもできる。風洞２の外周にはパッキン材１８が貼設され、パイプ１間の密閉性が確保されている。パイプ１の室内側開口端には、図１に示すような筒部に同様にパッキン材１８が貼設された化粧グリル１９が装着される。本体フレーム３のフランジ部９の上側には、アンプ収納部２０が凹設され、電源コード２１がアンプ収納部２０に収められたアンプにカシメられ、屋外コンセント等から送風機への給電が可能になっている（図２参照）。   In the blower, the motor 5 is attached to the mounting legs 15 formed on the rim of the opening 8 on the outdoor side of the wind tunnel 2 at intervals of 120 degrees in the circumferential direction extending outward in the center line direction. The suction side of the axial direction dimension of the blower is disposed in the wind tunnel 2 by approximately ½ (see FIGS. 1 and 3). A mounting portion 17 extending in the center line direction of the wind tunnel 2 is formed on the free end side of each mounting leg 15, and a flange of the outer shell of the motor 5 is screwed to the mounting portion 17. If the mounting screws 16 are removed, the blower can be removed together with the impeller 4 from the main body frame 3 without the blades interfering with the mounting legs 15. The main body 6 is detachably held in the pipe 1 by a spring force of an attachment spring (not shown) provided on the outer periphery of the wind tunnel 2, but can be fixed to a wall surface with a flange portion 9 by screwing. A packing material 18 is affixed to the outer periphery of the wind tunnel 2 to ensure sealing between the pipes 1. A decorative grille 19 in which a packing material 18 is similarly attached to a cylindrical portion as shown in FIG. 1 is attached to the indoor-side opening end of the pipe 1. On the upper side of the flange portion 9 of the main body frame 3, an amplifier storage portion 20 is recessed, and a power cord 21 is crimped to the amplifier stored in the amplifier storage portion 20 so that power can be supplied to the blower from an outdoor outlet or the like. (See FIG. 2).

屋外フード７は、アルミニウム材等の金属材で構成され、本体フレーム３のフランジ部９にネジ付けされ、本体６の前面構造１１の外側を、モーター５とともに間隔をもって被覆する。屋外フード７の下部は屋外換気口として下向きに開放していて、防鳥や防虫のための格子を持つギャラリ２２が設けられている。屋外フード７と本体フレーム３の前面構造１１との係合は、本体フレーム３のフランジ部９の外周部に設けた一連の凹溝２３と屋外フード７の壁面側の縁部の嵌め合いになっており、雨水の浸入が防止されている。なお、羽根車４の羽根形状を変えることで、給気による換気を果たす換気装置ともなる。   The outdoor hood 7 is made of a metal material such as an aluminum material, is screwed to the flange portion 9 of the main body frame 3, and covers the outside of the front structure 11 of the main body 6 together with the motor 5 with a space. A lower portion of the outdoor hood 7 is opened downward as an outdoor ventilation opening, and a gallery 22 having a lattice for preventing birds and insects is provided. The engagement between the outdoor hood 7 and the front structure 11 of the main body frame 3 is a fit between a series of concave grooves 23 provided in the outer peripheral portion of the flange portion 9 of the main body frame 3 and the edge of the outdoor hood 7 on the wall surface side. Intrusion of rainwater is prevented. In addition, by changing the blade shape of the impeller 4, it becomes a ventilation device that performs ventilation by supplying air.

この換気装置においては、送風機は、室内外を連通させるパイプ１やダクト等に屋外側から挿入して装着した本体６から、屋外フード７を取外せば脱着することができ、施工は容易で、メンテナンスもし易い。そして、屋外フード７は、送風機の取付けやその他の機能部材を持たない単独の構成であり、本体６に対して着脱可能なため、通気開口部等に極普通に取付けられる屋外フードとも色調、意匠、デザイン等の共通化・標準化を実現でき、住居において外観意匠のまとまりの良い換気装置となる。本体フレーム３がコーキングフランジにおいてコーキング１２され、あるいはモルタル等で塗込まれても、屋外フード７は外すことができ、送風機の脱着も可能である。本体フレーム３は、金属製の屋外フード７で覆われていて、太陽の紫外線に晒されることがないので、大量生産の可能な合成樹脂の成型品として構成してもその劣化は防止される。   In this ventilator, the blower can be detached by removing the outdoor hood 7 from the main body 6 inserted and attached to the pipe 1 or duct etc. that communicates indoors and outdoors from the outdoor side, and the construction is easy. Easy maintenance. The outdoor hood 7 is a single structure that does not have a blower or other functional members, and can be attached to and detached from the main body 6. It is possible to realize standardization and standardization of the design and the like, and it becomes a ventilation device with a good appearance design in the residence. Even if the main body frame 3 is caulked 12 at the caulking flange or coated with mortar or the like, the outdoor hood 7 can be removed, and the blower can be attached and detached. Since the main body frame 3 is covered with a metal outdoor hood 7 and is not exposed to the sun's ultraviolet rays, its deterioration can be prevented even if it is formed as a synthetic resin molded product capable of mass production.

実施の形態２．
本実施の形態も実施の形態１と同様の換気装置に関するものであり、送風性能、静粛性能の改善を図ったものである。これらに係る構成以外は実施の形態１のものと同じである。従って、実施の形態１と同じ部分については、実施の形態１と同じ符号を用い、それらについての説明は省略する。図４は、本実施の形態の換気装置を施工状態で示す横断面図、図５は、同じく換気装置の正面図、図６は、換気装置のメンテナンス状態を示す斜視図である。 Embodiment 2. FIG.
The present embodiment also relates to a ventilation device similar to that of the first embodiment, and is intended to improve the blowing performance and the quiet performance. The configuration other than these is the same as that of the first embodiment. Therefore, the same parts as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof will be omitted. FIG. 4 is a cross-sectional view showing the ventilation device of the present embodiment in a construction state, FIG. 5 is a front view of the ventilation device, and FIG. 6 is a perspective view showing a maintenance state of the ventilation device.

本実施の形態の換気装置においては、送風機の羽根車４の後縁部が、風洞２の屋外側開口部８より少し屋外側に突き出して設けられ、本体フレーム３のフランジ部９に向き合う円盤状の風路部材２４が取付脚１５の取付部１７にモーター５のフランジとともに取付ネジ１６で共締めされている（図５参照）。風路部材２４は、吸音材が貼られるか、吸音機能を有する多孔質材料で形成され、モーター５の半径方向に羽根車４の外径より張り出していて、本体フレーム３のフランジ部９との間に遠心ディフューザ風路２５を形成している（図４参照）。吹出し気流の流れは、遠心ディフューザ風路２５により旋回成分を含む軸方向から放射成分の半径方向に変えられる。即ち、回転方向成分が小さくなり、小さくなった成分が静圧上昇に変換される。つまり、外風の影響を受け難い性能の良い換気装置となる。風路部材２４に吸音機能を備えることで、ギャラリ２２から伝播する外の音は風路部材２４に吸音され、室内へ到達することは至って少なくなる。風路部材２４によって、音の伝播も風洞２のベルマウスから直線的に風洞２内に向かう経路をとらず、半径方向から風洞２に向かう経路となるため、消音性能は優れたものとなる。これ以外の機能は実施の形態１のものと同じである。   In the ventilator of the present embodiment, the rear edge of the blower impeller 4 is provided so as to protrude slightly to the outdoor side from the outdoor opening 8 of the wind tunnel 2, and is a disc shape facing the flange portion 9 of the main body frame 3. The air passage member 24 is fastened together with the flange of the motor 5 to the attachment portion 17 of the attachment leg 15 with the attachment screw 16 (see FIG. 5). The air passage member 24 is made of a porous material to which a sound absorbing material is attached or has a sound absorbing function, and projects from the outer diameter of the impeller 4 in the radial direction of the motor 5, and is connected to the flange portion 9 of the main body frame 3. A centrifugal diffuser air passage 25 is formed between them (see FIG. 4). The flow of the blown airflow is changed by the centrifugal diffuser air passage 25 from the axial direction including the swirling component to the radial direction of the radiating component. That is, the rotational direction component is reduced, and the reduced component is converted into an increase in static pressure. That is, it becomes a ventilator with good performance that is hardly affected by the outside wind. By providing the air passage member 24 with a sound absorbing function, the outside sound that propagates from the gallery 22 is absorbed by the air passage member 24, and it is very unlikely that it reaches the room. Due to the air path member 24, sound propagation does not take a straight path from the bell mouth of the wind tunnel 2 into the wind tunnel 2, but a path from the radial direction toward the wind tunnel 2, so that the silencing performance is excellent. Other functions are the same as those of the first embodiment.
