【発明の属する技術分野】
本発明は、レンジフードファンの作動に伴う負圧化解消のために外気を給気する調理室用換気装置に関するものである。
【0002】
【従来の技術】
今日、省エネ、防音、断熱等の要望によって建物の気密化はより進行する傾向にあり、このような建物事情下にあっては調理に伴う燃焼廃ガス、調理臭、蒸気等の排気のためにレンジフードファンを運転すると、調理室は負圧になり、場合によってはストーブ、風呂の煙突からの逆流による爆発や、不完全燃焼による災害が起きる危険性がある。
このようなことから旧来、レンジフードファンによる燃焼廃ガス、調理臭、蒸気等の排気に伴なう調理室負圧化防止のためにレンジフードファンの作動に伴って外気を給気する給排気式のレンジフードファンが提供されている。
給排気式レンジフードファンは、燃焼廃ガス、調理臭、蒸気等を排気する排気ダクトと負圧化防止のために外気を給気する給気ダクトを共に建物の外壁まで配管し、そこで開口している。
【0003】
【発明が解決しようとする課題】
しかし、特にマンション等の集合住宅ではレンジフードファンが建物の外壁に面さずに住居の奥まった位置等の隣家との境界壁に設置されるケースが多く、このような場合には隣室である居室、寝室等の真上を経由して屋外まで配管される給気ダクトの長さが非常に長くなることから配管施工工事が面倒で且つ施工コストの高騰を招き、しかも専用の極めて長いダクトスペースを別途に確保する必要が生じる。
また、斯様な給排気式のレンジフードファンは、作動に伴って外気を直接給気することから、冬場では冷気を給気し、また夏場では高温の暖気を給気することになり、共に室内空調を阻害してしまう。
【0004】
本発明は、従来事情に鑑みてなされたもので、その目的とする処は簡単な構造でもって、冬場に排気風の熱によって熱交換された暖かい空気を天井裏空間から調理室に給気し且つ夏場に断熱効果と隣室(調理室、リビングルーム等生活空間として使用する室)の冷房効果とによって比較的温度が下げられた状態にある天井裏空間の空気を調理室に給気するようにして、前記問題点を一掃する調理用換気装置を提供することにある。
他の目的とする処はコールドドラフトが発生するような温度差が生じても外気を直接給気しない調理用換気装置を提供することにある。
【0005】
【課題を解決するための手段】
上記目的を達成するために講じた技術的手段は、請求項1は、レンジフードファンの排気路と、天井裏空間に臨む建物の外壁から屋外の外気を取込む外気取入路とを天井裏空間に設けた熱交換部を介して熱交換可能に構成し、調理室の天井に給気口を設け、前記熱交換部よりも上流側の外気取入路部分に熱交換部または天井裏空間どちらかに流路を切り替える切替部を設けると共に、前記熱交換部に熱交換された暖気の天井裏空間への放出部を設け、前記熱交換部を建物の外壁に近接させたことを要旨とする。
請求項2は、請求項1記載の熱交換部がドレンパンに載置されていることを要旨とする。
請求項3は、請求項1または2記載の給気口がレンジフードファンの作動・停止と連動して開閉するものであることを要旨とする。
【0006】
上記技術的手段によれば下記の作用がある。
(請求項1)冬場はレンジフードファンの排気路を流れる排気熱でもって屋外から取込まれた空気は加熱されて熱交換部に設けた放出部から天井裏空間に放出され、給気口から調理室に給気される。一方、夏場は屋外から取込まれた空気が熱交換部を介することなく断熱効果と隣室(調理室、リビングルーム等生活空間として使用する室)の冷房効果とによって比較的温度が下げられた状態にある天井裏空間に吸気されて、調理室に給気される。
また、コールドドラフトが発生する危険温度差になるようなことがあると外気に比べて暖かい天井裏空間の空気を室内に給気して、室内の温度は若干低下するものの、コールドドラフトの発生を抑制する。
更に、外気取入路から天井裏空間に外気を積極的に取入れて流通を良くし、夏場の天井裏空間の温度上昇を抑制する。
(請求項2)結露水をドレンパンから排出する。
(請求項3)冬場のレンジフードファン非作動時に給気口が閉口して、暖房設備によって暖められた調理室内の暖気を天井裏空間に逃さず、夏場のレンジフードファン非作動時に給気口が閉口して、冷房設備によって冷房された調理室内の冷気を天井裏空間に逃がさない。
【0007】
【発明の実施の形態】
次に、本発明の実施の形態を説明する。
図1乃至図3は第1の実施の形態を、また図4は第2の実施の形態を各々示している。
【0008】
符号Aは、マンション等の集合住宅において建物の外壁に面さない住居の奥まった位置に配された調理室に設置したレンジフードファンを示している。
このレンジフードファンAは排気装置の作動による調理室の負圧化によって自然給気するレンジフードファンである。
【0009】
このレンジフードファンAは、図示するようにフード本体a1の前方開放部を着脱可能な前板a2で被蓋し、内部に排気装置1を、またその前方に仕切板a3先端と天板部a4内面とに設けたフィルタ桟a5に亘ってフィルタa6を係脱可能に係止し、排気装置1に連絡して排気路(後述では排気ダクトとして説明する)a7を室外に配管し、また天板部a4上には同天板部a4先端に幕板a8を立設している。
図示は省略するが、給気口2を天板部a4の上部の天井部bに設け、幕板a8で隠すことは自由である。
【0010】
符号400 は、建物Bの天井裏空間b1の外壁b2に近接して配設された熱交換部である。
【0011】
熱交換部400 は、図2に示すように建物Bの外壁b2に近接する天井bの裏面位置に設置されている。
排気ダクトa7は、熱交換部400 に接続され、排気は排気ダクトa7から熱交換部400 を通過後排気ダクトa7’を通りキャップ900 から屋外に排出される。
一方、建物Bの外壁b2に一端を開口した外気取入路500 の他端は天井裏空間b1で切替部600 を経由し、熱交換部400 に接続されている。
401 は、熱交換部400 で熱交換された外気の天井裏空間b1への放出部(後述では第1放出部と称する)である。
【0012】
切替部600 は外気取入路500 から取入れた外気を熱交換部400 または天井裏空間b1のどちらかに流路を切り替える電動式の切替弁である。その切替部600 に熱交換部400 を介さず天井裏空間b1に放出する放出部(後述では第2放出部と称する)601 を設けている。
尚、前記第1放出部401 と第2放出部601 はその先端の開放部を各々図示するように多孔筒体で形成してある。
【0013】
符号700 は熱交換部400 を載置するドレンパンであり、そのドレン穴701 に短尺なホース800 等を接続し、外壁b2に開孔した小穴b2’から引き出して結露水を外部に放水できるようにしてある。
【0014】
給気口2は、図3に示すように天井bの開口12口縁裏面に裏打補強した補強桟22にネジ止めされる給気筒32と、その給気筒32に取付けられる化粧パネル42と、フィルタ52等とから形成されている。
【0015】
給気筒32は、中央部に交差部32a”が形成されるように十字状、放射状等の脚片32a’を設けた筒体32aの下端から天井b内面に当接するフランジ32bを周設し、そのフランジ32bを天井bにネジ100 止めし、前記脚片32a’間を通孔32cとしている。
【0016】
化粧パネル42は、前記給気筒32を室内側から被覆する程度の深さ、大きさを有する皿状に形成してある。
また、化粧パネル42は、前記給気筒32の交差部32a”と同様の交差部42a”をその交差部32a”の鉛直方向延長上に形成するように底部の殆どの部分を十字状、放射状等の脚片42a’で形成して、その脚片42a’間を給気孔42bとしており、交差部42a”を貫通する取付ネジ200 を前記給気筒32の交差部32a”に螺合締結して給気筒32に取付けられている。
【0017】
フィルタ52は、前記化粧パネル42における全給気孔42bを覆うことができる面積を有する平板状に形成してなり、外周に桟52aを備え、前記取付ネジ200 を挿通させた状態で桟52a部分を化粧パネル42の給気孔42b回りに残置された底部内面縁部分に載置してセットされている。
これにより、給気は給気筒32の脚片32a’間の通孔32c、フィルタ52、化粧パネル42の脚片42a’間の給気孔42bを経て調理室B’に供給される。
【0018】
従って、この第1の実施の形態の調理室用換気装置では、排気装置1を作動させると、天井裏空間b1の空気をレンジフードファンAの作動による室内負圧化に伴って調理室B’内に自然給気する。その際、冬場、切替部600 で外気取入路500 と熱交換部400 とを連通状態にしておくことで、排気ダクトa7を通過する排気で熱交換された暖かい外気が第1放出部401 から天井裏空間b1に供給されて、調理室B’の負圧化で給気口2から自然給気されて室内の暖房効果を向上させ、夏場、切替部600 を切り替えて第2放出部601 を開放しておくことで、外気を熱交換部400 を介することなく天井裏空間b1に第2放出部601 から放出して隣室(居室等)や当該室の室内冷房で比較的冷やされている天井裏空間b1の空気によって暖かい外気を冷やし、その温度を下げた天井裏空間の空気を調理室B’の負圧化で自然給気して室内(調理室)の冷房効果を阻害しないようにすることができる。
また、コールドドラフトが発生する危険温度差になるようなことがあっても外気に比べて暖かい天井裏空間b1の空気を室内に給気するので、室内の温度は若干低下するが、コールドドラフトによる室内暖房への悪影響を抑制できる。
これにより、冬場は熱交換された暖かな空気を、夏場(冬場以外の季節)は比較的冷やされている天井裏空間b1の空気を各々レンジフードファンA作動時に給気し、冬場は暖房効果を、また夏場は冷房効果を阻害しないで調理室B’に給気することができる。
しかも、調理室B’から建物Bの外壁b2までの非常に長い給気ダクトの配管スペースを無駄に確保する必要がないばかりでなく、給気ダクトを室外まで伸ばす大掛かりな配管工事自体も不要となる。
【0019】
次に第2の実施の形態を説明すると、この実施の形態は、前記給気口2がレンジフードファンAの作動・停止に連動して開閉するようにしたものである。
【0020】
給気口2は、図4に示すように天井bの開口62口縁裏面に裏打補強した補強桟72にネジ止めされる給気筒82と、その給気筒82に取付けられる化粧パネル92と、その化粧パネル92内を昇降動するシャッタ102 と、そのシャッタ102 を昇降動させる手段112 等から形成されている。
【0021】
給気筒82は、空気取り入れ用スリット82a’を有する逆向き有底筒状の本体82aの下端から天井b内面に当接するフランジ82bを周設し、そのフランジ82bを天井bにネジ300 止めすると共に、フランジ82b先端に弾性係合片82cを室内に向けて形成している。
【0022】
化粧パネル92は、前記本体82aを室内側から被覆する大きさの皿状を呈し、その開口縁を前記弾性係合片82cに係脱可能に係合して本体82aをカバーするように被装され、テーパー状の周面には適宜間隔をおいて給気孔92aが穿設されている。
【0023】
シャッタ102 は、前記化粧パネル92の底部の面積とほぼ同じ面積に形成すると共に、周縁に弾性体102 aを嵌着固定してなり、その弾性体102 aが化粧パネル92の底部内面に載置(当接)されるように下降した状態で給気孔92a、給気筒82、空気取り入れ用スリット82a’が連通されて調理室B’に給気し、弾性体102 aが前記給気筒のフランジ82bに当接するように上昇した状態で給気孔92aと給気筒82内との連通を遮断するようになっている。
【0024】
前記シャッタを昇降動させる手段112 は、前記本体82aの頂面に設けたギヤーモータ112 aと、そのギヤーモータ112 aの回転軸112 bにカップリング112 cを介して鉛直方向に垂設されたネジ棒112 dと、そのネジ棒112 dを貫通状に螺合し且つ周面に前記シャッタ102 を嵌合支持する案内体112 eとで形成されている。
また、シャッタ102 の所望位置には遊挿孔102 bが開孔され、フランジ82bに一端が止着されたガイド棒82dがその遊挿孔102 bに挿入されている。
【0025】
従って、この第2の実施の形態の調理室用換気装置では、レンジフードファンAの作動に連動してギヤーモータ112 aが正回転し、シャッタ102 がガイド棒82dでガイドしながら下降して化粧パネル92の底部内面に周縁の弾性体102 aを当接させる。これにより給気孔92a、給気筒82、空気取り入れ用スリット82a’が連通され、調理室B’に給気する。
レンジフードファンAの作動が停止すると、ギヤーモータ112 aが逆回転し、シャッタ102 をガイド棒82dでガイドしながら上昇させて給気筒82のフランジ82bに周縁の弾性体102 aを当接させる。これにより給気孔92aと給気筒82内との間が遮断され、給気されない。
この第2の実施の形態では、レンジフードファンA非作動時に給気口2が閉じて室内空調(夏場は冷房効果、冬場は暖房効果)が天井裏空間b1に逃げず、省エネになるし、調理室B’を快適に使用することができる。
【0026】
建物Bの外壁b2で開口した外気取入路500 の入口には前記排気ダクトa7’の出口と同様に図1に示すように防虫網901 を有するキャップ900 を接続する。
【0027】
尚、本考案は、屋外の外気を外気取入路で天井裏空間に取入れて自ずとその天井裏空間の流通を良くして温度を下げるようにして冷房効果の低下を抑制するようにしているから、高層ビルや集合住宅ばかりでなく、夏場に直射日光で加熱され易い戸建住宅を含む平屋や2階建の家屋であっても等しく利用できる。
【発明の効果】
本発明は以上のように構成したから下記の利点がある。
(請求項1)レンジフードファンの排気路と、天井裏空間に臨む建物の外壁から屋外の外気を取込む外気取入路とを天井裏空間に設けた熱交換部を介して熱交換可能に構成し、調理室の天井に給気口を設け、前記熱交換部よりも上流側の外気取入路部分に熱交換部または天井裏空間どちらかに流路を切り替える切替部を設けると共に前記熱交換部に熱交換された暖気の天井裏空間への放出部を設けて、冬場に排気熱で熱交換された暖かい空気を調理室に取り込むようにしたから、冬場に調理室をより快適に使用でき、また冬場以外の給気で熱交換が好ましくない場合には切り替えることができ、省エネになるばかりでなく、熱交換部を建物の外壁近傍に設けたことから、レンジフードファンから屋外まで伸びる大掛かりな給気ダクトの配管施工を行う必要がなくなる。
従って、大掛かりな給気ダクトの配管施工を行う必要なく、また冬場の暖房効果、夏場の冷房効果の低下を低く抑えて給気でき、施工性が良く且つ調理室を快適に使用できる換気装置を提供できる。
その上、コールドドラフトが発生する危険温度差になるようなことがあっても外気に比べて暖かい天井裏空間の空気を室内に給気するので、室内の温度は若干低下するが、コールドドラフトによる室内暖房への悪影響を抑制できる。
また、レンジフードファンの作動に伴って建物外から天井裏空間内に外気が導入されることになるから、天井裏の除湿、結露防止、カビの発生等が防止され、建物の寿命、保全にも有効である。
しかも、外気取入路から外気を積極的に取り入れるようにしていることから、夏場籠りがちな天井裏空間の流通を良くして、天井裏空間の温度を下げ、冷房効果の低下をより低く抑えて調理室に給気することができる。
(請求項2)熱交換部をドレンパンに載置したから、そのドレンパンに小さな穴を開け、その小穴に接続した短いホースを建物の外壁から外に出す簡単な方法で熱交換に伴って発生する結露水を排出処理することができる。
(請求項3)冬場のレンジフードファン非作動時には給気口が閉口して、暖房設備によって暖められた調理室内の暖気を天井裏空間に逃さず、夏場のレンジフードファン非作動時には同様に給気口が閉口して、冷房設備によって冷房された調理室内の冷気を天井裏空間に逃がさないから、レンジフードファン不使用時における冬場の暖房効果、夏場の冷房効果を阻害することが全くなくなり、省エネになるばかりでなくレンジフードファン不使用時における調理室の使用を快適にすることができる。

The present invention has been made in view of the conventional circumstances, and its intended process is to have a simple structure and supply warm air, which is heat-exchanged by the heat of exhaust air in the winter, from the ceiling space to the cooking room. In addition, in the summer, air in the ceiling space where the temperature is relatively lowered due to the heat insulation effect and the cooling effect of the adjacent room (room used as a living space such as a cooking room or living room) is supplied to the cooking room. An object of the present invention is to provide a cooking ventilator that eliminates the above problems.
Another object of the present invention is to provide a cooking ventilator that does not directly supply outside air even if a temperature difference that causes a cold draft occurs.
[0005]
[Means for Solving the Problems]
The technical means taken in order to achieve the above-mentioned object is that the first aspect of the present invention is that the exhaust passage of the range hood fan and the outside air intake passage for taking outdoor outside air from the outer wall of the building facing the ceiling back space. It is configured so that heat can be exchanged through a heat exchanging part provided in the space, an air supply opening is provided in the ceiling of the cooking chamber, and the heat exchanging part or the space behind the ceiling in the outside air intake passage part upstream of the heat exchanging part The gist is that a switching unit for switching the flow path is provided on either side, a discharge part to the ceiling back space of the warm air heat-exchanged is provided in the heat exchange part, and the heat exchange part is brought close to the outer wall of the building. To do.
The gist of claim 2 is that the heat exchanging part according to claim 1 is placed on a drain pan.

(Claim 1) In winter, air taken in from the outside with exhaust heat flowing through the exhaust passage of the range hood fan is heated and discharged from the discharge section provided in the heat exchange section to the ceiling space, and from the air supply opening. It is supplied to the cooking room. On the other hand, in summer, the air taken in from outside has a relatively low temperature due to the heat insulation effect and the cooling effect of the adjacent room (room used as a living space such as a cooking room or living room) without going through the heat exchanger. The air is sucked into the ceiling space and is supplied to the cooking room.
Also, if there is a dangerous temperature difference that generates a cold draft, the air in the ceiling space that is warmer than the outside air is supplied into the room, and the temperature inside the room slightly decreases, but the occurrence of a cold draft is not possible. Suppress.
Furthermore, outside air is actively taken into the ceiling space from the outside air intake path to improve the circulation, and the temperature rise in the ceiling space in the summer is suppressed.
(Claim 2) Condensed water is discharged from the drain pan.
(Claim 3) The air supply port is closed when the range hood fan is not in operation in the winter, so that the warm air in the cooking chamber heated by the heating facility is not released to the ceiling space, and the air supply port is not operated in the summer range hood fan Is closed, so that the cool air in the cooking chamber cooled by the cooling system is not released to the ceiling space.

And an air supply port is provided in the ceiling of the cooking chamber, and a switching unit that switches the flow path to either the heat exchange unit or the ceiling space is provided in the outside air intake passage portion upstream of the heat exchange unit and the heat A warming air that has been heat-exchanged by exhaust heat in the winter is taken into the cooking room by providing a discharge part to the ceiling space for the warm air that has been heat-exchanged in the exchange, so that the cooking room can be used more comfortably in the winter. It can also be switched when heat exchange is not desirable due to air supply other than in winter, not only saving energy, but also providing a heat exchanging part near the outer wall of the building, so it extends from the range hood fan to the outdoors Large air supply duct piping Necessary to carry out is eliminated.
Therefore, it is not necessary to carry out large-scale air supply duct piping work, and it is possible to supply air with low deterioration of the heating effect in winter and the cooling effect in summer, providing a workability and comfortable use of the kitchen. Can be provided.
In addition, even if there is a dangerous temperature difference that causes a cold draft, the air in the ceiling space is warmer than the outside air, so the indoor temperature is slightly reduced. The adverse effect on room heating can be suppressed.
In addition, the outside air is introduced into the ceiling space from outside the building as the range hood fan operates, preventing dehumidification, condensation prevention, mold generation, etc. from the ceiling. Is also effective.
Moreover, since outside air is actively taken in from the outside air intake path, the circulation of the ceiling space that tends to be used in summer is improved, the temperature of the ceiling space is lowered, and the cooling effect is reduced further. You can supply air to the cooking room.
(Claim 2) Since the heat exchanging part is placed on the drain pan, a small hole is made in the drain pan, and a short hose connected to the small hole is brought out from the outer wall of the building with heat exchange. Condensed water can be discharged.
(Claim 3) When the range hood fan is not in operation in the winter, the air supply port is closed, so that the warm air in the cooking chamber heated by the heating equipment is not released to the ceiling space, and is similarly supplied when the range hood fan in the summer is not in operation. Since the air vent closes and the cold air in the cooking room cooled by the cooling system does not escape to the ceiling space, the heating effect in the winter when the range hood fan is not used, and the cooling effect in the summer are completely prevented. In addition to saving energy, the kitchen can be used comfortably when the range hood fan is not used.
