The oil collected by the provided cooking-use ventilation filter 12 and passed through the cooking-use ventilation filter 12 adheres to the cooking-use ventilation blades 9A. The cooking ventilation path 5 is not used for general ventilation, and dust during general ventilation does not adhere to the filter 12 for cooking ventilation and the blades 9A for cooking ventilation, and becomes dust only during cooking. The adhesion of is reduced.

また、調理時換気用ダンパー7で調理時換気用経路5の開口面積を調節して排気用モーター13を変更しないで、調理時の換気に必要な最適な風量を全体換気風量に影響を及ぼすことなく設定できる。   In addition, adjusting the opening area of the cooking-use ventilation path 5 with the cooking-use ventilation damper 7 and changing the exhaust motor 13 does not affect the overall ventilation air-flow, which is necessary for ventilation during cooking. It can be set without.

次に、部屋全体の換気では、全体換気用吸込み口10に設けた全体換気用フィルター14で室内を浮遊している埃を捕集する。そして調理時の油煙や油の飛散によるフィルター14への油の付着を防止できる。   Next, in the ventilation of the whole room, dust floating in the room is collected by the whole ventilation filter 14 provided in the suction opening 10 for the whole ventilation. And the adhesion of the oil to the filter 14 by the oil smoke at the time of cooking or the scattering of oil can be prevented.

また、全体換気風量についても、全体換気用ダンパー8で全体換気用経路6の開口面積を調節して、部屋の広さに対応した最適な風量に、調理時の換気風量に影響を及ぼすことなく調整できる。   Also, with regard to the overall ventilation airflow, the opening area of the overall ventilation path 6 is adjusted by the overall ventilation damper 8 so that the optimum airflow corresponding to the size of the room is not affected by the ventilation airflow during cooking. Can be adjusted.

このように実施の形態1の発明によれば、吸気口1と排気口2を有し、内部に排気送風機3を設けた排気ユニット4の吸気口1に連通し設けられるフード15の吸込み経路を調理時換気用経路5と全体換気用経路6の二風路で形成し、調理時と全体換気時の吸込み口を分け、調理時換気用の羽根と全体換気用の羽根を一体の両吸込みの羽根9とし、風路途中に調理時換気用ダンパー7と全体換気用ダンパー8を設けたので、調理時に発生する油煙は調理時換気用吸込み口11に設置された調理時換気用フィルター12で捕集し、全体換気時の部屋全体の換気では全体換気用吸込み口10に設けた全体換気用フィルター14で室内を浮遊している埃を捕集することが可能となり、調理時換気用フィルター12への油と埃の混在した固着を防止でき、調理時換気と全体換気の羽根を一体とし、モーターを共用しながら、羽根9に付着する油と埃を分離付着させることができるので、調理時換気用フィルター12の掃除性と羽根9の掃除性の改善を図ることとなる。   As described above, according to the invention of the first embodiment, the intake path of the hood 15 that has the intake port 1 and the exhaust port 2 and is provided in communication with the intake port 1 of the exhaust unit 4 in which the exhaust blower 3 is provided. It is formed with two air passages, the route for cooking ventilation 5 and the route 6 for general ventilation, and separates the intake port for cooking and general ventilation. Since the blade 9 is provided with the cooking ventilation damper 7 and the overall ventilation damper 8 in the middle of the air passage, oil smoke generated during cooking is captured by the cooking ventilation filter 12 installed in the cooking ventilation inlet 11. It is possible to collect dust floating in the room by the general ventilation filter 14 provided in the suction port 10 for general ventilation in the ventilation of the whole room at the time of general ventilation. Prevents sticking of oil and dust The cooking ventilation and the whole ventilation blade are integrated, and the oil and dust adhering to the blade 9 can be separated and adhered while sharing the motor. Therefore, the cleaning performance of the cooking ventilation filter 12 and the cleaning of the blade 9 can be achieved. It will improve the sex.

また、全体換気用吸込み口10を調理時排気用吸込み口11から離れたフード15の前側面に設けたので、調理時の油煙や油の飛散により、全体換気用吸込み口10に設けた全体換気用フィルター14へ油が付着することを防止して、全体換気用フィルター14の掃除性を改善できることとなる。   Further, since the entire ventilation inlet 10 is provided on the front side surface of the hood 15 away from the cooking exhaust outlet 11, the entire ventilation provided in the entire ventilation inlet 10 due to the scattering of oil smoke and oil during cooking. This prevents oil from adhering to the filter 14 and improves the cleanability of the overall ventilation filter 14.

また、風路を切り替える調理時換気用ダンパー7と全体換気用ダンパー8に風路を開口面積を調節する機構を設けることにより、調理時、全体換気時の換気風量を変更可能としたので、排気用モーター13を変更しないで調理時換気に必要な最適な風量に設定でき、全体換気風量については部屋の広さに対応した最適な風量を設定することが可能となり、それぞれの風量設 定時に互いに設定の影響を及ぼすことなく必要風量に調整できることとなる。   Further, by providing a mechanism for adjusting the opening area of the air passage in the cooking ventilation damper 7 and the overall ventilation damper 8 for switching the air passage, the ventilation air volume at the time of cooking and the overall ventilation can be changed. It is possible to set the optimal air volume necessary for ventilation during cooking without changing the motor 13, and it is possible to set the optimal air volume corresponding to the size of the room for the overall ventilation air volume. It will be possible to adjust to the required air volume without affecting the settings.

(Embodiment 2)
As shown in FIG. 2, the exhaust fan for cooking ventilation and the overall ventilation are separately provided as the cooking ventilation fan 3 </ b> A and the overall ventilation fan 3 </ b> B with respect to the first embodiment. In place of the filter for cooking ventilation, a rectifying plate 17 that receives oil smoke rising from the range and leads to the cooking suction inlet 11A formed around is provided, and the hood facing the cooking ventilation suction port 11A A collision plate 18 is provided in 15A.

また、調理時換気用送風機3Aは、遠心力で風を送り出す後向きブレードの羽根19を有した送風機としている。また、全体換気用送風機3Bは、全体換気用経路内に通風するように設けられ、その吹出し口をフード15A下面側に向く誘導流用経路6Bと、調理時換気用送風機3Aの下流に連通する側に向く排気用経路6Aとの二方向に設けており、誘導流経路6Bは、フード15A下面に調理時換気用吸込み口11A側に向いて開口した誘導流用吹出し口21に連通するとともに、この経路を開閉する誘導流用ダンパー8Bを備え、排気用経路6Aには、この経路を開閉する全体換気用ダンパー8Aを備えている。なお、全体換気用吸込み口10Aは、調理時換気用吸込み口11Aから離れたフード15Aの天面側から、全体換気用送風機3Bの羽根20に直接吸い込まれる位置に設け、細かい目の全体換気用フィルター14Aを備えている。そして、全体換気用吸込み口10Aに設けられる全体換気用フィルター14A部に自動的に全体換気用フィルター14Aを清掃する掃除機構22を装着している。   Further, the cooking-use ventilation blower 3A is a blower having blades 19 of a backward-facing blade that sends out the wind by centrifugal force. Further, the general ventilation fan 3B is provided so as to ventilate the entire ventilation path, and is connected to the induction flow path 6B whose outlet is directed to the lower surface side of the hood 15A and the downstream side of the cooking ventilation fan 3A. The induction flow path 6B communicates with the induction flow outlet 21 that opens on the lower surface of the hood 15A toward the suction inlet 11A for cooking ventilation. The exhaust flow path 6A is provided with a general ventilation damper 8A that opens and closes this path. The overall ventilation inlet 10A is provided at a position directly sucked into the blades 20 of the overall ventilation fan 3B from the top surface side of the hood 15A away from the cooking ventilation inlet 11A. A filter 14A is provided. A cleaning mechanism 22 that automatically cleans the overall ventilation filter 14A is attached to the overall ventilation filter 14A provided in the overall ventilation inlet 10A.

また、フード15A前面に設けられたスイッチ23にはレンジの操作信号を受信する受信部24、コンロの温度や磁界を検知する温度検知部25、磁界検知部26を備えている。   The switch 23 provided on the front surface of the hood 15A includes a receiving unit 24 that receives a range operation signal, a temperature detecting unit 25 that detects the temperature and magnetic field of the stove, and a magnetic field detecting unit 26.

上記構成において、レンジ(図示せず)から上昇する油煙を排出するときには、油煙を含んだ空気が衝突板18に衝突し向きを変える際に油煙が衝突板18に付着し、油を捕集することが可能となり、更に衝突板18を通過した油煙や埃も羽根19に衝突した際に羽根19に付着し捕集されるが、羽根19のブレードが後ろ向きになっていることで付着した油や埃は羽根19の外側に飛び散らせることができる。   In the above configuration, when oil smoke rising from a range (not shown) is discharged, when the air containing oil smoke collides with the collision plate 18 and changes its direction, the oil smoke adheres to the collision plate 18 and collects oil. In addition, oil smoke and dust that have passed through the collision plate 18 adhere to and be collected by the blade 19 when it collides with the blade 19. The dust can be scattered outside the blades 19.

さらに全体換気時は、室内に通じる誘導流用経路6Bに設置された誘導流用ダンパー8Bを閉じ、排気用経路6Aに設置された全体換気用ダンパー8Aを開くことで室内の全体換気ができ、調理時換気では、排気用経路6Aに設置された全体換気用ダンパー8Aを閉じ、誘導流用経路6Bの誘導流用ダンパー8Bを開くことでフード15Aに設けた誘導流用吐出し口21から誘導流を吐出すことができる。   Further, during general ventilation, the indoor ventilation can be performed by closing the induction flow damper 8B installed in the induction flow path 6B leading to the room and opening the general ventilation damper 8A installed in the exhaust path 6A. In ventilation, the general ventilation damper 8A installed in the exhaust path 6A is closed, and the induction flow damper 8B of the induction flow path 6B is opened to discharge the induction flow from the induction flow discharge port 21 provided in the hood 15A. Can do.

また、レンジの運転に応じてレンジフードを調理時換気運転と全体換気運転に切り替えることができる。   In addition, the range hood can be switched between a cooking-time ventilation operation and an overall ventilation operation according to the operation of the range.

このようなことから、定期的なフィルターの掃除をなくし、レンジフードを自動運転することでフィルターへの油と埃の付着を制御することができる。   For this reason, it is possible to control the adhesion of oil and dust to the filter by eliminating periodic cleaning of the filter and automatically operating the range hood.

このように実施の形態2の発明によれば、調理時換気用と全体換気用の排気送風機をそれぞれに個別に設け、調理時換気用経路5Aには、衝突板18と後向きブレードの羽根19を設け、全体換気用吸込み口10Aには、細かい目の全体換気用フィルター14Aと羽根20を組み合わせて備えたので、調理時換気は油煙を含んだ空気が衝突板18に衝突し向きを変える際に油煙が衝突板18に付着することで、フィルターと同等の油捕集性能を確保しながらフィルター機能をなくし掃除性を向上させ、フィルターの目詰まりによる性能低下という事態をなくすことができる。さらに衝突板18を通過した油煙や埃は羽根19に衝突した際に羽根19に付着し捕集されるが、羽根19のブレードが後ろ向きになっていることで、付着した油や埃は羽根19の外側に飛び散り、羽根19への汚れが付着しづらく長期間使用しても性能の低下を防止することとなる。   As described above, according to the second embodiment of the present invention, the exhaust fan for cooking ventilation and the whole ventilation are individually provided, and the collision plate 18 and the blade 19 of the backward blade are provided in the cooking ventilation path 5A. Since the overall ventilation inlet 10A is provided with a combination of a fine-mesh general ventilation filter 14A and a blade 20, ventilation during cooking is performed when air containing oil smoke collides with the collision plate 18 and changes its direction. By attaching the oil smoke to the collision plate 18, it is possible to eliminate the filter function while improving the oil collecting performance equivalent to that of the filter, to improve the cleaning performance, and to eliminate the performance deterioration due to the clogging of the filter. Further, when the oil smoke or dust that has passed through the collision plate 18 collides with the blade 19, it adheres to the blade 19 and is collected. However, since the blade of the blade 19 faces rearward, the attached oil or dust is removed from the blade 19. Even if it is used for a long period of time, it is difficult for dirt to adhere to the blades 19 to adhere to the outside of the blades 19 and to prevent deterioration in performance.

また、全体換気用送風機3Bを設け、その吐出し口を排気用経路6A,誘導流経路6Bの二経路設け、それぞれに全体換気用ダンパー8A,誘導流用ダンパー8Bを設けて、調理時換気と全体換気時でダンパーの開閉を切り替え、調理時には誘導流としてフード15Aの誘導流用吐出し口21から吐出すことを可能としたので、全体換気時は室内に通じる経路に設置された誘導流用ダンパー8Bを閉じ、屋外に通じる経路に設置された全体換気用ダンパー8Aを開くことで室内の全体換気ができ、調理時換気では屋外に通じる経路に設置された全体換気用ダンパー8Aを閉じ、室内に通じる経路の誘導流用ダンパー8Bを開くことでフード15Aに設けた誘導流用吐出し口21から誘導流を吐出すことにより、新たに誘導流用のファンを追加することなく捕集性能の向上と結露の発生を軽減することが可能となる。   Also, an overall ventilation fan 3B is provided, and its discharge port is provided with an exhaust path 6A and an induction flow path 6B, and an overall ventilation damper 8A and an induction flow damper 8B are provided respectively for ventilation and cooking. The damper can be opened and closed during ventilation, and can be discharged from the induction flow outlet 21 of the hood 15A as an induction flow during cooking. Therefore, the induction flow damper 8B installed on the path leading to the room can be opened during general ventilation. Closed and opened the general ventilation damper 8A installed in the path leading to the outdoors, the whole room can be ventilated. In cooking ventilation, the overall ventilation damper 8A installed in the path leading to the outdoors is closed and the path leading to the room By opening the induction flow damper 8B, the induction flow is discharged from the induction flow discharge port 21 provided in the hood 15A, and a new induction flow fan is added. It is possible to reduce the occurrence of improvement and condensation of Rukoto without collecting performance.

また、全体換気用風路に設けるフィルター部に掃除機構22を設けて自動的に全体換気用フィルター14Aを掃除可能としたので、定期的に全体換気用フィルター14の掃除をしなくても目詰まりによる全体換気風量の性能低下の防止を図ることが可能となる。   In addition, since the cleaning mechanism 22 is provided in the filter portion provided in the air passage for general ventilation so that the general ventilation filter 14A can be automatically cleaned, clogging is required even if the general ventilation filter 14 is not periodically cleaned. Therefore, it is possible to prevent a decrease in the performance of the overall ventilation airflow.

また、フード15A前面に設けられたスイッチ23にはレンジの操作信号を受信する受信部24、コンロの温度や磁界を検知する温度検知部25、磁界検知部26を設けたので、レンジの運転に応じてレンジフードを調理時換気運転と全体換気運転に切り替え、自動運転可能としたので、調理時換気運転で全体換気され、調理時換気用吸込み口に埃が付着することを防止することが可能となる。   In addition, the switch 23 provided on the front surface of the hood 15A is provided with a receiving unit 24 for receiving a range operation signal, a temperature detecting unit 25 for detecting the temperature and magnetic field of the stove, and a magnetic field detecting unit 26. In response, the range hood is switched between a ventilation operation during cooking and a general ventilation operation to enable automatic operation, so that the entire ventilation is provided during cooking ventilation operation, and dust can be prevented from adhering to the suction vent for cooking. It becomes.

局所換気と全体換気で成分の異なる汚染空気を捕集して集塵する集塵装置の用途にも適用できる。   It can also be applied to dust collectors that collect and collect polluted air with different components in local and general ventilation.
