請求項４に記載の発明は、第１の本体局所吸込口および第２の本体局所吸込口はダクトを介して建物内のトイレ、クローゼット、押し入れ、または納戸に連通させたことにより、扉などの隙間から本体下面の本体吸込口へ連通する換気経路とは独立した換気経路を有することで、小風量の換気風量でも他の部屋に臭いや汚染された空気が漏れることがなく、またクローゼットなどの小さな空間にも省スペースで換気口を設けることができ、確実に湿気や淀んだ空気の排出を行うことできる。
【００１７】
請求項５に記載の発明は、第１の本体局所吸込口が設けられる本体の一側面に隣り合う側面に設けた第２の本体局所吸込口を塞ぐとともに、本体天面に設けた第２の本体局所吸込口にダクトを接続する構成としたことにより、換気装置本体の側面に障害物が隣接していた場合に置いても１箇所または２箇所から局所排気を行うことができる。
【００１８】
以下、本発明の実施の形態を図面を参照して説明する。
【００１９】
（実施の形態１）
図１および図２に示すように、換気装置本体１は建物内の屋根裏空間および１階天井裏空間に設置され、給気用ファン９により新鮮外気を屋外給気口２から導入し、換気装置本体１に内蔵する熱交換素子部３を通過して室内給気口４を経て室内に供給する。このとき屋外給気口２から導入された外気には、屋外給気口２付近に浮遊している粗塵および虫などが混入している。一方、室内汚染空気は換気装置本体１の下面に形成された本体吸込口５から排気用ファン１０によって導入され、熱交換素子部３を通過し前記新鮮空気と熱交換されて屋外排気口６を経て屋外に排気される。このとき、熱交換素子部３は排気空気の熱量を給気空気に回収する機能を有している。屋外給気口２から導入される新鮮外気と本体吸込口５から導入される室内汚染空気は熱交換素子部３を経て電動機７に同一軸８にて連結された給気用ファン９と排気用ファン１０により移送される。
【００２０】
換気装置本体１には局部排気口１１より導入された一部の室内汚染空気を熱交換素子部３を通過せず排気用ファン１０により屋外排気口６を経て室外に排気する経路を有する。図３に示すように、室内と連通する室内空気供給ダクト２６と接続される本体吹出口２８を有する換気装置本体１の一側面に第１の本体局所吸込口１２を設ける。第１の本体局所吸込口１２を設けた一側面を除く他の側面には第２の本体局所吸込口１３を設け、換気装置本体１の天面には第２の本体局所吸込口１４を設ける。第１の本体局所吸込口１２と第２の本体局所吸込口１３はそれぞれダクトと接続されて室内に開口する局部排気口１１と連通する。
【００２１】
屋外給気口２より導入された空気には粗塵・虫などが混入しているので、屋外給気口２とダクトを介して連通された本体外気取入口２９に設置された虫捕集部としての粗塵・防虫フィルター１５により粗塵・虫などが捕集され、さらに微細な粉塵は粗塵・防虫フィルター１５に隣接する給気清浄フィルター１６により捕集され、清浄された後に室内に供給される。一方、室内汚染空気に混入する塵埃は本体吸込口５に設置された化粧パネル１７に付属される排気フィルター１８により捕集される。
【００２２】
図４に換気装置本体１の内部構造を示す。局部排気口１１より室内空気排出ダクト２７を介して導入された室内汚染空気は、第１の本体局所吸込口１２および第２の本体局所吸込口１３から熱交換素子部３を通過せず排気用ファン１０により本体吹出口３０に連通された室内空気排出ダクト２７を介して屋外排気口６を経て屋外に排出され、本体吸込口５より導入された室内汚染空気は熱交換素子部３を通過して排気用ファン１０により本体吹出口３０に連通された室内空気排出ダクト２７を介して屋外排気口６を経て屋外に排出される。本体吸込口５より導入された室内汚染空気は、熱交換素子部３により屋外給気口２より導入された新鮮外気と熱交換されるため、第１の局所吸込口１２および第２の局所吸込口１３より換気装置本体１に導入された室内汚染空気と本体吸込口５より導入された室内汚染空気との温度差が生じる。この温度差が生じた室内汚染空気が排気用ファン１０により交わるので、これらの室内汚染空気が交わる空間に断熱材３１を設け、第２の局所吸込口１３を熱交換素子部３より最も離れた位置に配設したことで温度差のある室内汚染空気の混在領域を少なくし結露を防ぐことができる。また第２の局所吸込口１３は換気装置本体１の側面の上方に配設されているので、換気装置本体１を野縁に直接取り付ける場合にも野縁によって吸込口を塞がれることなく室内空気排出ダクト２７の接続を行うことができる。
【００２３】
第１の本体局所吸込口１２、第２の本体局所吸込口１３または天面に設けた第２の本体局所吸込口１４は、屋外給気口２より導入された外気を室内空気供給ダクト２６を介して室内給気口４より各部屋に新鮮外気を供給し、各部屋の扉などの開口部から換気装置本体１の下面に設けられた本体吸込口５より室内空気排出ダクト２７を介して屋外排気口６より室内汚染空気を排出する換気経路とは独立して、本体吸込口５が設置された部屋から離れたトイレ、クローゼットまたは押入れなどから局部排気口１１より室内空気排出ダクト２７を介して直接排気する換気経路を形成しているので、トイレなど局所的に空気が汚れる可能性のある場所から他の部屋へ汚染空気の流出を防ぐことができる。また第１の本体局所吸込口１２、第２の本体局所吸込口１３または天面に設けた第２の本体局所吸込口１４より導入された室内汚染空気は熱交換素子部３を通過せず直接排気させることで、換気装置本体１内部の本体外気吸込口２９から本体吹出口２８へ連通する換気経路へ熱交素子部３と熱交素子部３を保持しているエレメントホルダー２４または熱交換素子部３およびエレメントホルダー２４を保持し、空気供給経路および空気排出経路を形成しているエレメント枠２５などとの微小な隙間からの臭いのもれなどを防ぐことができる。また書庫、キッチンまたはガレージなどにも局部排気口１１を設置することもできる。
【００２４】
ダクト接続アダプター１９は第１の本体局所吸込口１２が設けられる換気装置本体１の一側面と一体的に形成されており、局所排気を行う場合には施工時に別途ダクト接続口部材を取り付ける必要はなく、また、図５に示すように、第１の本体局所吸込口１２には着脱可能なキャップ２１が取り付けられているので、局所排気を行わない場合にはキャップ２１によって排気口を塞ぐことができる。さらにダクト接続アダプター１９を換気装置本体１の一側面と一体成形することにより気密経路確保が向上され、ネジ止め不要な構造となっているので工数を大幅に削減できる。
【００２５】
第１の局部換気口１２を有する一側面を除く他の側面に設けた第２の本体局所吸込口１３と本体天面に設けた第２の本体局所吸込口１４にダクト接続口部材２２を設置することにより、換気装置本体１台で４箇所まで局所排気が可能である。これらの本体局所吸込口は本体の４方向に設けられているので第１の本体局所吸込口１２と第２の本体局所吸込口１３と本体天面に設けた第２の本体局所吸込口１４を選択することにより、換気装置本体１の側面近傍に障害物などがある場合に容易にダクトの接続が可能となる。例えば、ツーバイーフォー住宅の１階天井裏に本体を設置する際には本体設置空間の高さ方向に制約があるため、図６に示すように根太２３の間に換気装置本体１を設置した場合、根太２３と換気装置本体１の隙間はおよそ３５ｍｍしかなく、第２の本体局所吸込口１３を使用して局所排気を行うにはダクト接続口部材２２を換気装置本体１に設置しなければならないが、ダクト接続口部材２２の風路方向の長さは約６０ｍｍであるので換気装置本体１に隣接する根太２３に開口部を設けなければならない。また、根太２３の幅は３８ｍｍなので根太２３に換気装置本体１を近接して設置したとしてもダクト接続部材２２に室内空気排出ダクト２７を接続するのは困難であり、作業性を高めるためには根太２３に大きな開口部を設けなければならなくなる。一方、第１の本体局所吸込口１２または本体天面に設けた第２の本体局所吸込口１４を使用する場合は、室内空気排出ダクト２７をダクト接続アダプター１９および第２の本体局所吸込口１４に設置されたダクト接続口部材２２に容易に接続でき、室内空気排出ダクト２７を接続するための開口部を根太２３に設けることなく局所排気ができる。またこの時、使用しない第２の本体局所吸込口１３は遮蔽板２０により塞ぐことになる。
【００２６】
また、本体局所吸込口が４方向に配設されているので、塩化ビニルパイプのような硬質でダクト配管方向に制限がある直管型のダクトを使用する場合にも局部排気口１１に接続された室内空気排出ダクト２７の排気経路においてダクト方向を変えるための湾曲した接続部材を設けることなく局所排気ができる。
【００２７】
【発明の効果】以上のように本発明によれば、室内の空気を吸い込むために下面に本体吸込口を設けた箱体状の本体に、室内に強制的に外気を供給するために前記室内と連通する本体吹出口を有する前記本体の一側面に設けた第１の本体局所吸込口と、前記本体吹出口を有する前記本体の一側面を除く他の側面に設けた第２の本体局所吸込口とを備えたことにより、同時に複数の部屋から局所排気ができ、また自由に局所排気をするためのダクト接続方向を選択できるので本体側面に隣接して障害物がある場合でもダクト配管施工が可能となる。
【００２８】
また、第１の本体局所吸込口が設けられる本体の一側面と一体的にダクト接続アダプターを形成したことにより、施工時に別途ダクト接続用のアダプター部を取り付ける必要はなく施工時の工数を削減できる。

[0018]
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
(Embodiment 1)
As shown in FIGS. 1 and 2, the ventilation device main body 1 is installed in an attic space and a first floor ceiling space in a building, and fresh air is introduced from an outdoor air supply port 2 by an air supply fan 9 to provide a ventilation device. The air passes through the heat exchange element unit 3 incorporated in the main body 1 and is supplied to the room through the indoor air supply port 4. At this time, the outside air introduced from the outdoor air supply port 2 contains dust and insects floating near the outdoor air supply port 2. On the other hand, the indoor contaminated air is introduced by the exhaust fan 10 from the main body suction port 5 formed on the lower surface of the ventilator main body 1, passes through the heat exchange element section 3, and exchanges heat with the fresh air, and passes through the outdoor exhaust port 6. After being exhausted outside. At this time, the heat exchange element section 3 has a function of recovering the heat quantity of the exhaust air into the supply air. Fresh outside air introduced from the outdoor air supply port 2 and indoor contaminated air introduced from the main body suction port 5 are passed through the heat exchange element section 3 to the electric motor 7 via the same shaft 8 and the air supply fan 9 and the exhaust air. It is transferred by the fan 10.
[0020]
The ventilator body 1 has a path for exhausting some indoor contaminated air introduced from the local exhaust port 11 to the outside through the outdoor exhaust port 6 by the exhaust fan 10 without passing through the heat exchange element section 3. As shown in FIG. 3, a first main body local suction port 12 is provided on one side surface of a ventilator main body 1 having a main body air outlet 28 connected to an indoor air supply duct 26 communicating with the room. A second main body local suction port 13 is provided on the other side surface except one side where the first main body local suction port 12 is provided, and a second main body local suction port 14 is provided on the top surface of the ventilator main body 1. . Each of the first main body local suction port 12 and the second main body local suction port 13 is connected to a duct and communicates with the local exhaust port 11 that opens to the room.
[0021]
Since dust and insects are mixed in the air introduced from the outdoor air inlet 2, the insect trapping unit installed at the outside air inlet 29 of the main body that communicates with the outdoor air inlet 2 through a duct. The coarse dust and insect filter 15 collects coarse dust and insects, and the finer dust is collected by the air supply cleaning filter 16 adjacent to the coarse dust and insect filter 15 and is supplied to the room after being cleaned. Is done. On the other hand, dust mixed in the indoor contaminated air is collected by an exhaust filter 18 attached to a decorative panel 17 installed in the main body suction port 5.
[0022]
FIG. 4 shows the internal structure of the ventilation device main body 1. The indoor contaminated air introduced from the local exhaust port 11 through the indoor air discharge duct 27 does not pass through the first main body local suction port 12 and the second main body local suction port 13 through the heat exchange element unit 3 and is exhausted. The indoor contaminated air discharged through the outdoor air outlet 6 through the indoor air discharge duct 27 communicated with the main body outlet 30 by the fan 10 to the outside, and introduced from the main body inlet 5 passes through the heat exchange element unit 3. Then, the air is discharged outside through the outdoor air outlet 6 through the indoor air discharge duct 27 which is connected to the main body outlet 30 by the exhaust fan 10. The indoor contaminated air introduced from the main body suction port 5 exchanges heat with the fresh outside air introduced from the outdoor air supply port 2 by the heat exchange element unit 3, and thus the first local suction port 12 and the second local suction port A temperature difference occurs between the indoor contaminated air introduced into the ventilator body 1 through the port 13 and the indoor contaminated air introduced through the main body suction port 5. Since the indoor contaminated air having this temperature difference intersects with the exhaust fan 10, a heat insulating material 31 is provided in a space where the indoor contaminated air intersects, and the second local suction port 13 is furthest away from the heat exchange element unit 3. By arranging at the position, the mixed area of indoor contaminated air having a temperature difference can be reduced, and dew condensation can be prevented. In addition, since the second local suction port 13 is disposed above the side surface of the ventilation device main body 1, even when the ventilation device main body 1 is directly mounted on the field edge, the indoor port is not blocked by the field edge without being blocked by the field edge. The connection of the air discharge duct 27 can be made.
[0023]
The first main body local suction port 12, the second main body local suction port 13, or the second main body local suction port 14 provided on the top surface is used to supply the outside air introduced from the outdoor air supply port 2 to the indoor air supply duct 26. Fresh air is supplied to each room from the indoor air supply port 4 via the indoor air supply port 4, and from the opening such as the door of each room through the indoor air discharge duct 27 from the main body suction port 5 provided on the lower surface of the ventilator main body 1. Independently of the ventilation path for discharging indoor contaminated air from the exhaust port 6, a toilet, a closet, a closet, or the like away from the room in which the main body intake port 5 is installed, from the local exhaust port 11 via the indoor air discharge duct 27 via a room air outlet duct 27. Since a ventilation path for directly exhausting air is formed, it is possible to prevent the outflow of contaminated air from a place where air may be locally contaminated such as a toilet to another room. In addition, the indoor contaminated air introduced from the first main body local suction port 12, the second main body local suction port 13 or the second main body local suction port 14 provided on the top surface does not directly pass through the heat exchange element unit 3 but directly. By exhausting the air, the heat exchange element unit 3 and the element holder 24 holding the heat exchange element unit 3 or the heat exchange element to the ventilation path communicating from the main body outside air intake port 29 to the main body outlet port 28 inside the ventilator main body 1. By holding the portion 3 and the element holder 24, it is possible to prevent odor leakage from a minute gap with the element frame 25 forming the air supply path and the air discharge path. The local exhaust port 11 can also be installed in a library, kitchen or garage.
[0024]
The duct connection adapter 19 is formed integrally with one side surface of the ventilator main body 1 in which the first main body local suction port 12 is provided, and when performing local exhaust, it is not necessary to separately attach a duct connection port member at the time of construction. In addition, as shown in FIG. 5, a removable cap 21 is attached to the first main body local suction port 12, so that when the local exhaust is not performed, the exhaust port can be closed by the cap 21. it can. Furthermore, by forming the duct connection adapter 19 integrally with one side surface of the ventilator main body 1, the airtight path can be secured more securely, and the structure does not need to be screwed, so that the number of steps can be significantly reduced.
[0025]
A duct connection port member 22 is installed on a second main body local suction port 13 provided on the other side except one side having the first local ventilation port 12 and a second main body local suction port 14 provided on the main body top surface. By doing so, it is possible to locally exhaust up to four locations with one ventilator body. Since these main body local suction ports are provided in four directions of the main body, the first main body local suction port 12, the second main body local suction port 13, and the second main body local suction port 14 provided on the main body top surface are provided. By making a selection, it is possible to easily connect the duct when there is an obstacle or the like near the side surface of the ventilation device main body 1. For example, when installing the main body behind the first floor ceiling of a two-by-four house, there is a restriction in the height direction of the main body installation space, so the ventilation device main body 1 is installed between the joists 23 as shown in FIG. In this case, the gap between the joist 23 and the ventilator main body 1 is only about 35 mm, and in order to perform local exhaust using the second main body local suction port 13, the duct connection port member 22 must be installed in the ventilator main body 1. However, since the length of the duct connection port member 22 in the air path direction is about 60 mm, an opening must be provided in the joist 23 adjacent to the ventilator body 1. Also, since the width of the joist 23 is 38 mm, it is difficult to connect the indoor air discharge duct 27 to the duct connecting member 22 even if the ventilator body 1 is installed close to the joist 23. A large opening must be provided in the joist 23. On the other hand, when using the first local main body suction port 12 or the second main body local suction port 14 provided on the top surface of the main body, the indoor air discharge duct 27 is connected to the duct connection adapter 19 and the second main body local suction port 14. Can be easily connected to the duct connection port member 22 installed in the room, and local exhaust can be performed without providing an opening for connecting the indoor air discharge duct 27 in the joist 23. At this time, the unused second main body local suction port 13 is closed by the shielding plate 20.
[0026]
Further, since the main body local suction ports are provided in four directions, even when a straight pipe type duct such as a vinyl chloride pipe which is hard and has a restriction in a duct pipe direction is used, it is connected to the local exhaust port 11. Local exhaust can be performed without providing a curved connecting member for changing the duct direction in the exhaust path of the indoor air discharge duct 27.
[0027]
As described above, according to the present invention, in order to forcibly supply outside air into the room, the inside of the room is forcibly supplied to a box-shaped main body having a main body suction port provided on the lower surface for sucking room air. A first main body local suction port provided on one side of the main body having a main body outlet communicating with the second main body local suction provided on another side except one side of the main body having the main body outlet; By having a mouth, local exhaust can be performed from multiple rooms at the same time, and the duct connection direction for local exhaust can be freely selected, so even if there is an obstacle adjacent to the side of the main body, duct piping construction It becomes possible.
[0028]
Further, since the duct connection adapter is formed integrally with one side surface of the main body where the first main body local suction port is provided, it is not necessary to separately install an adapter for duct connection at the time of construction, and the number of steps at the time of construction can be reduced. .
