Description
本発明は、ガスコンロ、電磁調理器等の厨房器具の上方に設けられ、調理時に発生する煙や熱気等を捕集して屋外に排出するレンジフードのファン及び排気経路構成に関するものである。 The present invention relates to a fan and exhaust path configuration of a range hood provided above a kitchen appliance such as a gas stove, an electromagnetic cooker, etc., for collecting smoke, hot air, and the like generated during cooking and discharging the hood to the outside.
従来、レンジフードのファンへの油埃汚れ付着量の低減及びお手入れ頻度削減方法として、排気用のファンの上流に円盤形に形成した回転自在のフィルターを設けて排気ガス中の油埃を捕集するとともに、排気運転中に円盤形フィルターを高速回転させることで捕集した油埃を油分捕集部材に捕集するレンジフードが知られている（例えば、特許文献１参照）。以下、そのレンジフードについて図８を参照しながら説明する。 Conventionally, as a method of reducing the amount of dust and dirt adhering to the fan of the range hood and the frequency of maintenance, a rotatable filter formed in the shape of a disk is provided upstream of the exhaust fan to catch oil and dust in the exhaust gas. 2. Description of the Related Art There is known a range hood that collects and collects oil and dust collected by rotating a disc-shaped filter at a high speed during an exhaust operation by an oil collecting member (for example, see Patent Document 1). Hereinafter, the range hood will be described with reference to FIG.
図８に示すように、排気用のファン１０５と、ファン１０５の上流に円盤形のフィルター１１０およびフィルターを高速回転駆動させるモータ１１１とを有し、排気運転中に円盤形フィルター１１０を高速回転させることにより、ファンへの油埃汚れの付着量を低減するとともにフィルターの目詰まりを防止することができる。 As shown in FIG. 8, an exhaust fan 105, a disk-shaped filter 110 upstream of the fan 105, and a motor 111 for rotating the filter at a high speed are provided, and the disk-shaped filter 110 is rotated at a high speed during the exhaust operation. Thus, it is possible to reduce the amount of dust and dirt adhering to the fan and prevent the filter from being clogged.
このような従来のレンジフードにおいては、排気用ファンのモータに加えて円盤形のフィルターを高速回転させるモータも電力を消費するために、運転時の消費電力が大きいという課題およびフィルターの高速回転により騒音が発生するという課題を有している。 In such a conventional range hood, in addition to the motor of the exhaust fan, the motor for rotating the disc-shaped filter at a high speed also consumes power. There is a problem that noise is generated.
そこで本発明は上記従来の課題を解決するものであり、静音化かつ消費電力を抑えたレンジフードを提供することを目的とする。 Therefore, the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a range hood with reduced noise and reduced power consumption.
そして、この目的を達成するために、本発明の一態様に係るレンジフードは、吸込口および排気口を有するフード本体と、前記フード本体に内蔵された送風機と、前記送風機の風量を制御する制御部と、を備え、前記送風機の軸方向は水平方向であり、前記送風機の吐出口から吹き出される空気は、鉛直方向上方に向かって吹き出されて前記排気口から排気され、前記制御部は、通常運転モードと、油飛散運転モードと、を有し、前記通常運転モードでは、前記吸込口から吸い込んだ油煙を前記排気口から排気し、前記油飛散運転モードでは、前記通常運転モードより大きい回転数で前記送風機を運転することとしたものであり、これにより所期の目的を達成するものである。 In order to achieve this object, a range hood according to one embodiment of the present invention includes a hood main body having a suction port and an exhaust port, a blower built in the hood main body, and a control for controlling an air volume of the blower. And an axial direction of the blower is a horizontal direction, air blown out from a discharge port of the blower is blown vertically upward and is exhausted from the exhaust port, and the control unit includes: It has a normal operation mode and an oil scattering operation mode, wherein in the normal operation mode, the oil smoke sucked from the suction port is exhausted from the exhaust port, and in the oil scattering operation mode, the rotation is larger than the normal operation mode. The number of the blowers is to be operated, thereby achieving the intended purpose.
本発明によれば、油飛散運転によって一度ファンに付着した油埃汚れを吹き飛ばすことで排気ファンの油埃汚れ付着量を低減できる。また、円盤形フィルターなどを高速回転することが不要となるので、運転時の消費電力を抑えたレンジフードを提供できる。 ADVANTAGE OF THE INVENTION According to this invention, the amount of oil and dirt adhesion | attachment of an exhaust fan can be reduced by blowing off the oil dirt which once adhered to the fan by the oil scattering operation. In addition, since it is not necessary to rotate a disk-shaped filter or the like at high speed, a range hood with reduced power consumption during operation can be provided.
本発明の一態様に係るレンジフードは、吸込口および排気口を有するフード本体と、フード本体に内蔵された送風機と、送風機の風量を制御する制御部と、を備え、送風機の軸方向は、水平方向であり、送風機の吐出口から吹き出される空気は、鉛直方向上方に向かって吹き出されて排気口から排気され、制御部は、通常運転モードと、油飛散運転モードと、を有し、通常運転モードは、吸込口から吸い込んだ油煙を排気口から排気するモードであり、油飛散運転モードは、通常運転モードより高い（大きい）回転数で送風機を運転するモードである。これにより、油飛散運転モードにおいて送風機を高速回転させることで、送風機に付着した油等の汚れを吹き飛ばし、お手入れ性が向上するという効果を奏する。また、ファンの回転軸を水平方向にして上向きに吹き出す（ファンを縦向きに設置する）構成とすることで、ファンと油捕集機構部との距離を大きくとることができるので、騒音が小さくなるという効果を奏する。 A range hood according to one embodiment of the present invention includes a hood main body having an intake port and an exhaust port, a blower built in the hood main body, and a control unit that controls a flow rate of the blower, and the axial direction of the blower is: In the horizontal direction, the air blown from the discharge port of the blower is blown vertically upward and exhausted from the exhaust port, and the control unit has a normal operation mode and an oil scattering operation mode, The normal operation mode is a mode in which oil smoke sucked in from the suction port is exhausted from the exhaust port, and the oil scattering operation mode is a mode in which the blower is operated at a higher (larger) rotation speed than the normal operation mode. Thus, by rotating the blower at a high speed in the oil scattering operation mode, dirt such as oil adhering to the blower is blown off, and there is an effect that the careability is improved. In addition, since the configuration is such that the rotation axis of the fan is horizontal and blows upward (the fan is installed vertically), the distance between the fan and the oil collecting mechanism can be increased, so that noise is reduced. It has the effect of becoming.
また、通常運転モード終了後に油飛散運転モードに移行するという構成であってもよい。これにより、通常運転モードにおいて付着した油等の汚れを、運転の都度吹き飛ばし、送風機に汚れがたまりにくくなるという効果を奏する。 Further, the configuration may be such that the mode is shifted to the oil scattering operation mode after the end of the normal operation mode. Thus, the dirt such as oil adhering in the normal operation mode is blown off every time the operation is performed, so that there is an effect that dirt hardly accumulates in the blower.
また、吸込口から吸い込まれた油煙に含まれる油を捕集する油捕集機構部を備え、油抜き穴を有するケーシングは、送風機を内包し、吸込口から吸い込まれた油煙に含まれる油は、ケーシングの内壁に付着した後、油抜き穴を通って油捕集機構部に回収されるという構成であってもよい。これにより、油飛散運転モードで吹き飛ばされた油を効率的に油捕集機構部にて回収することができるという効果を奏する。 Further, an oil collecting mechanism for collecting oil contained in the oil smoke sucked from the suction port is provided, and a casing having an oil vent hole includes a blower, and the oil contained in the oil smoke sucked from the suction port is After being attached to the inner wall of the casing, the oil collecting mechanism may be collected through the oil drain hole. Thereby, there is an effect that the oil blown off in the oil scattering operation mode can be efficiently collected by the oil collecting mechanism.
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）
本発明の一態様に係るレンジフードは、ガスコンロやＩＨコンロ等の厨房器具（図示せず）の上方に設けられる。レンジフードは、フード本体１と、整流板４と、油捕集機構部９と、制御部（図示せず）と、を有する。
(Embodiment 1)
The range hood according to one embodiment of the present invention is provided above a kitchen appliance (not shown) such as a gas stove or an IH stove. The range hood has a hood body 1, a current plate 4, an oil collecting mechanism 9, and a controller (not shown).
フード本体１は、汚染された空気を吸込む吸込口２と、排気装置３（ダクトカバー）と、を有する。排気装置３は、ファン５と、ファンモータ１１と、ケーシング６と、を有する。ファン５は、フード本体１の内部に設けられ、吸込口２から吸込まれた空気を排気する。ファン５は、鉛直方向上方に向かって吹き出すように吐出口が設けられる。ファン５の回転軸方向は水平方向である。なお、ここでいう「水平」とは完全な水平のみならず、水平から１０度ほど傾けたものも含むものとする（図５（ｂ）参照）。このように、ファン５を水平方向から前方に傾かせることでファン５をお手入れする際の脱着性が向上する。 The hood main body 1 has a suction port 2 for sucking contaminated air, and an exhaust device 3 (duct cover). The exhaust device 3 has a fan 5, a fan motor 11, and a casing 6. The fan 5 is provided inside the hood main body 1 and exhausts the air sucked from the inlet 2. The fan 5 is provided with a discharge port so as to blow out vertically upward. The rotation axis direction of the fan 5 is horizontal. Note that the “horizontal” here includes not only perfect horizontal but also one tilted by about 10 degrees from horizontal (see FIG. 5B). In this manner, by inclining the fan 5 forward from the horizontal direction, the detachability at the time of cleaning the fan 5 is improved.
ケーシング６はファン５を内包する。ケーシング６は、後述する油飛散運転により吹き飛ばされた油汚れが油捕集機構部９まで流れ落ちる連続した壁面と底部の油抜き穴１０とを有する。油抜き穴１０は、ケーシング６下部のたとえば中央であって油捕集機構部９の上方に設けられる。ケーシング６の壁面に付着した油汚れは図４における矢印Ａに示すように、ケーシング６の壁面を伝って下部にある油抜き穴１０へ導かれる。そして油抜き穴１０から油捕集機構部９に滴下する。このように、ケーシング６壁面を流れ落ちる面を曲面で構成することにより効率良く油埃汚れを油捕集機構部９へ集めることができる。すなわち、後述する油飛散運転により吹き飛ばした油埃汚れがケーシング６壁面を伝って下方へ流れ落ち、効率的に油捕集機構部９に集めることができる。またケーシング６に設けた油抜き穴１０から油捕集機構部９に直接油が流れ落ちるために、油を捕集する過程で汚染される構成部材を最小限に抑えたお手入れしやすいレンジフードを提供できる。 The casing 6 contains the fan 5. The casing 6 has a continuous wall surface on which oil dirt blown off by the oil scattering operation described later flows down to the oil collecting mechanism 9 and an oil drain hole 10 at the bottom. The oil drain hole 10 is provided, for example, at the center of the lower portion of the casing 6 and above the oil collecting mechanism 9. The oil stain adhering to the wall surface of the casing 6 is guided along the wall surface of the casing 6 to the oil drain hole 10 at the lower portion as shown by an arrow A in FIG. Then, the oil is dropped from the oil drain hole 10 to the oil collecting mechanism 9. In this way, by configuring the surface that flows down the wall surface of the casing 6 as a curved surface, it is possible to efficiently collect oil and dirt in the oil collecting mechanism 9. That is, oil and dirt blown off by the oil scattering operation described below flows down the wall of the casing 6 and can be efficiently collected in the oil collecting mechanism 9. In addition, since the oil flows directly from the oil drain hole 10 provided in the casing 6 to the oil collecting mechanism 9, a range hood which is easy to clean and minimizes components contaminated in the process of collecting the oil is provided. Can be provided.
ファンモータ１１の運転によりファン５は回転する。 The operation of the fan motor 11 causes the fan 5 to rotate.
油捕集機構部９は、フード本体１に取り付けられる。油捕集機構部９は、ケーシング６の下方に設けられる。油捕集機構部９はたとえば箱型形状であって、内部に油汚れを含んだ空気が流入し、油捕集機構部９の内壁に接触することで、油を回収する構成であってもよい。 The oil collecting mechanism 9 is attached to the hood main body 1. The oil collecting mechanism 9 is provided below the casing 6. The oil collecting mechanism 9 has, for example, a box shape, and is configured to collect oil by allowing air containing oil dirt to flow into the inside and contacting the inner wall of the oil collecting mechanism 9. Good.
整流板４は、例えば方形状で、吸込口２に取り付けられる。整流板４の周囲から吸込口２へと空気が流入する。 The current plate 4 has a rectangular shape, for example, and is attached to the suction port 2. Air flows from the periphery of the current plate 4 into the suction port 2.
排気装置３の天面には屋外と連通したダクト等を介して連通する排気口１２を設ける。 The top surface of the exhaust device 3 is provided with an exhaust port 12 that communicates via a duct or the like that communicates with the outside.
フード本体１および排気装置３の内部に、ファン５を介し吸込口２と排気口１２を結ぶ通風路を形成する。 Inside the hood body 1 and the exhaust device 3, a ventilation path connecting the suction port 2 and the exhaust port 12 via the fan 5 is formed.
油捕集機構部９は、例えば金属製であって、ファン５と吸込口２との間に設けられ、厨房器具から発生する油煙や周囲に浮遊する埃等を捕集する。 The oil collecting mechanism 9 is made of, for example, metal, and is provided between the fan 5 and the suction port 2 to collect oil smoke generated from kitchen appliances and dust floating around.
制御部は、通常運転モードと、油飛散運転モードと、を有する。 The control unit has a normal operation mode and an oil scattering operation mode.
通常運転モードは、ファン５の運転により、吸込口２から汚染された空気を吸い込み、排気口１２から排気するモードである。通常運転モードにおいてはファン５の回転数が異なる「弱・中・強」のいずれか１つの運転を使用者が選ぶことができる構成であってもよい。このとき例えば、弱、中、強の順にファンの回転数が大きくなる運転である。 The normal operation mode is a mode in which the contaminated air is sucked in from the suction port 2 by the operation of the fan 5 and exhausted from the exhaust port 12. In the normal operation mode, the configuration may be such that the user can select any one of “weak, medium, and strong” operations in which the rotation speed of the fan 5 is different. At this time, for example, the operation is such that the rotation speed of the fan increases in the order of low, medium, and high.
また、通常運転モードにおいて残置運転を行うという構成であってもよい。ここで、残置運転とは、「切」信号すなわちファン停止信号を受信してから、ファン５を一定時間運転させた後にファン５を停止する運転をいう。 Further, the configuration may be such that the remaining operation is performed in the normal operation mode. Here, the residual operation refers to an operation of stopping the fan 5 after operating the fan 5 for a certain period of time after receiving the “off” signal, that is, the fan stop signal.
油飛散運転モードは、ファン５を通常運転モード終了ごとに高速回転することで油埃汚れを吹き飛ばすモードである。油飛散運転モードでのファン５の回転数は例えば、１２００ｒ／ｍｉｎである。油飛散運転モードでのファン５の回転数は通常運転モード時、特に、残置運転時の回転数より大きい回転数である。 The oil scattering operation mode is a mode in which the fan 5 is rotated at a high speed every time the normal operation mode ends to blow off oil and dirt. The rotation speed of the fan 5 in the oil scattering operation mode is, for example, 1200 r / min. The rotation speed of the fan 5 in the oil scattering operation mode is higher than the rotation speed in the normal operation mode, particularly, in the remaining operation.
ここで、図６を用いて、通常運転モードおよび油飛散運転モードについて説明する。 Here, the normal operation mode and the oil scattering operation mode will be described with reference to FIG.
運転開始後、制御部は、通常運転モードで運転中であるかを検知する。通常運転モードではない場合（例えば、油飛散運転モードで運転している場合）には、「切」信号を受信した後、残置運転を行わずに運転を終了する。 After the start of the operation, the control unit detects whether the vehicle is operating in the normal operation mode. When the operation is not in the normal operation mode (for example, when the operation is in the oil scattering operation mode), the operation is terminated without performing the remaining operation after receiving the “OFF” signal.
「弱・中・強」のいずれかの通常運転モードにて運転をしている場合、制御部は、通常運転モードで一定時間運転しているかを検知する。一定時間運転をしていない場合には、「切」信号を受信した後、残置運転を行わずにファン５を停止し、運転を終了する。通常運転モードにて一定時間を超えて運転した後に「切」信号を受信した場合、残置運転を実施する。そして、残置運転実施後に、通常運転モードから油飛散運転モードに移行する。そして、油飛散運転モードにおいて、ファン５を通常運転モードより大きい（高い）、または通常運転モードの最大回転数にて数秒間高速回転させる油飛散運転を実施する。油飛散運転終了後にファン５を停止させ、運転を終了する。 When operating in any of the normal operation modes of “weak, medium, and strong”, the control unit detects whether the vehicle is operating in the normal operation mode for a certain period of time. When the operation has not been performed for a certain period of time, after receiving the “OFF” signal, the fan 5 is stopped without performing the remaining operation, and the operation is terminated. When the "OFF" signal is received after the operation has been performed for a certain period of time in the normal operation mode, the remaining operation is performed. Then, after performing the remaining operation, the operation mode is shifted from the normal operation mode to the oil scattering operation mode. Then, in the oil scattering operation mode, an oil scattering operation in which the fan 5 is rotated at a higher speed than the normal operation mode for a few seconds at the maximum rotation speed of the normal operation mode is performed. After the oil scattering operation is completed, the fan 5 is stopped, and the operation is terminated.
なお、「切」信号は、レンジフードの制御部からのファン停止信号でも、連動する調理機器からのファン停止信号であってもよい。 The “off” signal may be a fan stop signal from a control unit of the range hood or a fan stop signal from an associated cooking appliance.
以上の構成により、通常運転モードにおいて付着した油等の汚れを、運転の都度吹き飛ばすことで、送風機に汚れがたまりにくくなり、使用者のお手入れ性が向上する。また、本構成であれば円盤形のフィルターを高速回転するモータを別途搭載する必要がないため、運転消費電力を抑えたレンジフードを提供することができる。 With the above configuration, the dirt such as oil adhered in the normal operation mode is blown off every time the operation is performed, so that the dirt hardly accumulates in the blower, and the careability of the user is improved. Further, according to this configuration, it is not necessary to separately mount a motor for rotating the disc-shaped filter at a high speed, so that it is possible to provide a range hood with reduced operation power consumption.
また、図５に示すように、ファン５を上方向に吹き出すように（縦向きに）設置することで、油捕集機構部９とファン５との距離が大きくなる。このように、油捕集機構部９とファン５を離して配置することで通風抵抗が下がり、騒音低下の効果を奏する。 In addition, as shown in FIG. 5, by installing the fan 5 so as to blow up (vertically), the distance between the oil collecting mechanism 9 and the fan 5 is increased. Thus, by arranging the oil collecting mechanism 9 and the fan 5 apart, the ventilation resistance is reduced, and the effect of noise reduction is achieved.
ここで、図７を用いて、通風抵抗低下と騒音低下の関係について説明する。 Here, the relationship between the reduction in ventilation resistance and the reduction in noise will be described with reference to FIG.
ある運転状態において、送風機の「静圧―風量特性」と通風抵抗との交点Ａで使用している。ここで通風抵抗が下がると、静圧―風量特性に沿って使用点が交点Ｂに移動するが、風量を一定に保つ制御により使用点がＣに移動する。使用点ＣはＡに比べて低い回転数での運転であるため、騒音低下の効果を奏する。 In a certain operation state, the blower is used at the intersection A between the “static pressure-air volume characteristic” and the ventilation resistance. Here, when the ventilation resistance decreases, the point of use moves to the intersection B in accordance with the static pressure-air volume characteristics, but the point of use moves to C by control for keeping the air volume constant. Since the use point C is operated at a lower rotational speed than A, the use point C has an effect of reducing noise.
このように、本実施の形態に係るレンジフードでは、ファンとフィルターとの距離が大きくなることで、通風抵抗が下がり、静音化を実現することができる。 As described above, in the range hood according to the present embodiment, since the distance between the fan and the filter is increased, the ventilation resistance is reduced, and noise can be reduced.
以上、本発明に係るレンジフードについて、実施の形態に基づいて説明したが、本発明は、実施の形態に限定されるものではない。本発明の趣旨を逸脱しない限り、当業者が思いつく各種変形を本実施の形態に施したものや、異なる実施の形態における構成要素を組み合わせて構築される形態も、本発明の範囲内に含まれる。 As described above, the range hood according to the present invention has been described based on the embodiment, but the present invention is not limited to the embodiment. Unless departing from the gist of the present invention, various modifications conceivable by those skilled in the art are applied to the present embodiment, and forms configured by combining components in different embodiments are also included in the scope of the present invention. .
本発明に係るレンジフードは、送風機への油汚れの付着を低減するものであるので、台所の壁面に設置するキャビネット等にも有用である。 Since the range hood according to the present invention reduces the adhesion of oil stains to a blower, it is also useful for a cabinet or the like installed on a kitchen wall.
