以下、本発明の実施の形態について図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施の形態１）
図１から図３に示すように、本発明のレンジフード１は、ＩＨ調理機器２の上部に取り付けられ、レンジフード１内部には送風機３が構成されている。送風機３は、使用者がＩＨ調理機器２を使って調理を行った際に発生する油煙等を吸い上げ、吐出口４から屋外へ排出するものである。 (Embodiment 1)
As shown in FIGS. 1 to 3, the range hood 1 of the present invention is attached to the upper part of the IH cooking device 2, and the blower 3 is configured inside the range hood 1. The blower 3 sucks up the oil smoke generated when the user cooks using the IH cooking device 2 and discharges it from the discharge port 4 to the outside.

フロントフード５下面のフロントフード開口６の内部に、センサーケース７を設け、センサーケース７内には、分割壁８により、レンジフード１の外周側８Ａに受光素子区画９が、レンジフード１の内周側８Ｂに温度センサー区画１０が形成される。受光素子区画９下面と、温度センサー区画１０下面にはそれぞれ、受光素子用開口１１と、温度センサー用開口１２を有し、受光素子区画９内に受光素子１３を受光素子用開口１１に向けて配置し、温度センサー区画１０内には、赤外線式温度センサー１４を温度センサー用開口１２に向けて配置する。受光素子用開口１１には、近赤外線を透過しやすく、それ以外を透過しにくい近赤外線フィルター１５を設け、温度センサー用開口１２には、遠赤外線を透過しやすく、それ以外を透過しにくい遠赤外線フィルター１６を設ける。フロントフード開口６には、近赤外線と遠赤外線を透過しやすい保護カバー１７を、フロントフード５外面と面一になるように設ける。諸説があるが一般的に、近赤外線は波長０．７５μｍから４μｍの電磁波であり、遠赤外線は波長４μｍから１０００μｍの電磁波である。なお、近赤外線フィルター１５、遠赤外線フィルター１６、保護カバー１７としては、透過させたい赤外線以外の波長を透過しにくいよう処理したアクリル樹脂やポリエチレン樹脂等を用いる。   A sensor case 7 is provided inside a front hood opening 6 on the lower surface of the front hood 5, and a light receiving element section 9 is provided on the outer peripheral side 8 </ b> A of the range hood 1 in the sensor case 7 by a dividing wall 8. A temperature sensor section 10 is formed on the peripheral side 8B. The lower surface of the light receiving element section 9 and the lower surface of the temperature sensor section 10 have a light receiving element opening 11 and a temperature sensor opening 12, respectively, and the light receiving element 13 faces the light receiving element opening 11 in the light receiving element section 9. In the temperature sensor section 10, an infrared temperature sensor 14 is disposed toward the temperature sensor opening 12. The light-receiving element opening 11 is provided with a near-infrared filter 15 that easily transmits near-infrared light and does not easily transmit the other, and the temperature sensor opening 12 is easy to transmit far-infrared light and is not easily transmitted through the other. An infrared filter 16 is provided. The front hood opening 6 is provided with a protective cover 17 that easily transmits near infrared rays and far infrared rays so as to be flush with the outer surface of the front hood 5. Although there are various theories, generally, the near infrared ray is an electromagnetic wave having a wavelength of 0.75 μm to 4 μm, and the far infrared ray is an electromagnetic wave having a wavelength of 4 μm to 1000 μm. In addition, as the near-infrared filter 15, the far-infrared filter 16, and the protective cover 17, an acrylic resin, a polyethylene resin, or the like processed so as to hardly transmit wavelengths other than the infrared light that is to be transmitted is used.

赤外線式温度センサー１４は通称サーモパイルとも呼ばれ、２種類の金属で構成されたセンサー素子が発熱体から発生する遠赤外線を検知すると金属接点間に起電力を発生する。その起電力の発生量に基づいて物体表面温度やその変化を検出するという使い方ができる。本実施の形態１では、図１に示すように、ＩＨ調理機器２上の遠赤外線を広範囲で検知できるようにしている。   The infrared temperature sensor 14 is commonly called a thermopile, and generates an electromotive force between metal contacts when a sensor element made of two kinds of metals detects far infrared rays generated from a heating element. Based on the amount of electromotive force generated, the object surface temperature and its change can be detected. In the first embodiment, as shown in FIG. 1, far infrared rays on the IH cooking appliance 2 can be detected in a wide range.

使用者がレンジフード１の下方に配置したＩＨ調理機器２で加熱調理を開始すると、送信部１８から近赤外線の加熱開始信号がレンジフード１に向けて発信される。保護カバー１７と近赤外線フィルター１５は、双方とも、近赤外線を透過しやすいため、近赤外線の加熱開始信号は、保護カバー１７、近赤外線フィルター１５を透過して、受光素子１３に到達する。受光素子１３で検知した加熱開始信号は、レンジフード１内に設けた制御部（図示せず）に送られる。また、ＩＨ調理機器２での加熱により、鍋１９、調理物２０の温度が上昇し、鍋１９、調理物２０から放射される遠赤外線が増加する。保護カバー１７と遠赤外線フィルター１６は、双方とも、遠赤外線を透過しやすいため、鍋１９、調理物２０から放射される遠赤外線は、保護カバー１７、遠赤外線フィルター１６を透過して、赤外線式温度センサー１４に到達する。赤外線式温度センサー１４で検知した遠赤外線による起電力は、レンジフード１内に設けた制御部に送られる。制御部は、受光素子１３で検知した、ＩＨ調理機器２の送信部１８からの加熱開始信号と、赤外線式温度センサー１４で検知した、鍋１９、調理物２０から放射される遠赤外線での起電力により、送風機３の運転回転数を制御し、排気風量を調節する。   When the user starts cooking with the IH cooking device 2 disposed below the range hood 1, a near-infrared heating start signal is transmitted from the transmitter 18 toward the range hood 1. Since both the protective cover 17 and the near-infrared filter 15 easily transmit near-infrared light, the near-infrared heating start signal passes through the protective cover 17 and the near-infrared filter 15 and reaches the light receiving element 13. The heating start signal detected by the light receiving element 13 is sent to a control unit (not shown) provided in the range hood 1. Moreover, the temperature of the pan 19 and the food 20 increases due to the heating by the IH cooking device 2, and the far infrared rays emitted from the pan 19 and the food 20 increase. Since both the protective cover 17 and the far-infrared filter 16 easily transmit far-infrared rays, the far-infrared rays radiated from the pan 19 and the cooked product 20 are transmitted through the protective cover 17 and the far-infrared filter 16 to be infrared type. The temperature sensor 14 is reached. The electromotive force generated by the far infrared rays detected by the infrared temperature sensor 14 is sent to a control unit provided in the range hood 1. The control unit detects the heating start signal from the transmission unit 18 of the IH cooking appliance 2 detected by the light receiving element 13 and the far infrared ray emitted from the pan 19 and the cooked product 20 detected by the infrared temperature sensor 14. The operating rotational speed of the blower 3 is controlled by electric power, and the exhaust air volume is adjusted.

保護カバー１７は、フロントフード５内の受光素子１３、赤外線式温度センサー１４を、調理で発生する油煙や水蒸気から保護する役割を有するとともに、フロントフード５外面と面一としたことにより、外観を保つ役割も有する。また、保護カバー１７に油汚れが付着すると、受光素子１３、赤外線式温度センサー１４の感度が悪化するおそれがある。この油汚れは、フロントフード５下面を掃除する際に、保護カバー１７の油汚れを拭き取ればよい。   The protective cover 17 has a role of protecting the light receiving element 13 and the infrared temperature sensor 14 in the front hood 5 from oily smoke and water vapor generated by cooking, and is made flush with the outer surface of the front hood 5 so that the appearance is improved. It also has a role to keep. Moreover, if oil stains adhere to the protective cover 17, the sensitivity of the light receiving element 13 and the infrared temperature sensor 14 may be deteriorated. The oil stain may be wiped off from the protective cover 17 when the lower surface of the front hood 5 is cleaned.

また、近赤外線フィルター１５は、近赤外線を透過しやすく、それ以外を透過しにくいため、レンジフード１近傍に、照明器具からの外乱光や、窓から入る日光の外乱光がある場合でも、外乱光による、受光素子１３の感度悪化を防止できる。   Further, since the near-infrared filter 15 easily transmits near-infrared rays and does not easily transmit other infrared rays, even if there is disturbance light from the lighting fixture or sunlight disturbance entering from the window in the vicinity of the range hood 1, the disturbance Sensitivity deterioration of the light receiving element 13 due to light can be prevented.

同様に、遠赤外線フィルター１６は、遠赤外線を透過しやすく、それ以外を透過しにくいため、外乱光による、赤外線式温度センサー１４の感度悪化を防止できる。   Similarly, the far-infrared filter 16 can easily transmit far-infrared rays and hardly transmit other infrared rays, so that deterioration in sensitivity of the infrared temperature sensor 14 due to ambient light can be prevented.

赤外線式温度センサー１４は、レンジフード１の内周側に配置したので、鍋１９、調理物２０に、より近い距離となるため、検知感度の悪化を防止することができる。図２に、ＩＨ調理機器２の加熱部投影線２１を図示している。   Since the infrared type temperature sensor 14 is disposed on the inner peripheral side of the range hood 1, it is closer to the pan 19 and the food 20, so that it is possible to prevent deterioration in detection sensitivity. In FIG. 2, the heating part projection line 21 of the IH cooking appliance 2 is illustrated.

本実施の形態１では、加熱調理機器をＩＨ調理機器２としたが、ガス調理機器であってもよい。その場合、ガスの燃焼により放射される遠赤外線も、赤外線式温度センサー１４で検知する。また、ＩＨ調理機器２から発信される信号を、加熱開始信号としたが、加熱終了時の加熱終了信号、使用火力に応じて発信される火力信号、調理の種類に応じて発信される調理種類信号であってもよい。その場合、検知した信号に応じて、制御部が送風機の運転回転数を制御する。   In Embodiment 1, the cooking device is the IH cooking device 2, but it may be a gas cooking device. In that case, the far infrared rays radiated by the combustion of the gas are also detected by the infrared temperature sensor 14. Moreover, although the signal transmitted from IH cooking appliance 2 was made into the heating start signal, the heating end signal at the time of a heating end, the thermal power signal transmitted according to use thermal power, the cooking type transmitted according to the kind of cooking It may be a signal. In that case, a control part controls the driving | running rotation speed of a fan according to the detected signal.

このように本発明の実施の形態１のレンジフードによれば、フードに、加熱調理機器に配置された加熱物から発生する遠赤外線を検知する赤外線式温度センサーと、加熱調理機器から送信される近赤外線信号を検知する受光素子とを備え、前記赤外線式温度センサーと前記受光素子とは前記フードに設けられた検知用開口部から遠赤外線と近赤外線を検知し、前記検知用開口部に遠赤外線と近赤外線の両方を透過する保護カバーを設け、前記赤外線式温度センサーと前記保護カバー間に、遠赤外線以外の光線を遮断する遠赤外線フィルターを設け、前記受光素子と前記保護カバー間に、近赤外線以外の光線を遮断する近赤外線フィルターを設けたことにより、外乱光による受光素子と赤外線式温度センサーの感度の悪化を生じることなく、近赤外線と遠赤外線のセンサーユニットを一体化し、レンジフードのデザイン性を向上させることができる。   Thus, according to the range hood of Embodiment 1 of this invention, the infrared type temperature sensor which detects the far-infrared rays which generate | occur | produce from the heating thing arrange | positioned at the cooking appliance, and a cooking appliance are transmitted to a hood. A light-receiving element that detects a near-infrared signal, and the infrared temperature sensor and the light-receiving element detect far-infrared light and near-infrared light from a detection opening provided in the hood, and are distant from the detection opening. Provide a protective cover that transmits both infrared and near infrared, between the infrared temperature sensor and the protective cover, provided a far infrared filter that blocks light other than far infrared, between the light receiving element and the protective cover, By providing a near-infrared filter that blocks light other than near-infrared light, the sensitivity of the light-receiving element and infrared temperature sensor due to ambient light does not deteriorate. Integrating an outside line and far infrared sensor unit, it is possible to improve the design of the range hood.

また、保護カバー外面とフード本体外面を面一としたことにより、保護カバーの掃除性を向上させることができる。   Moreover, the cleaning performance of the protective cover can be improved by making the outer surface of the protective cover and the outer surface of the hood main body flush with each other.
