Description
本発明は、ハンディタイプの送風機に関するものであり、特に、手に持つか又は卓上等に載置することを選択して使用することが可能な送風機に関するものである。 The present invention relates to a hand-held blower, and particularly to a blower that can be held in the hand or placed on a tabletop.
従来、机上に載置して使用する送風機は、一般に、台座等を用いて送風機構等を支える構造を用いていた（例えば、特許文献１参照）。また、手に持って使用することを目的とした送風機では、台座や本体を小型で握り易い形状にすること等で対応するものが多かった。 BACKGROUND ART Conventionally, a blower used by being placed on a desk generally has a structure in which a pedestal or the like is used to support a blower mechanism or the like (see, for example, Patent Document 1). In addition, many blowers intended to be held in the hand have been designed so that their bases and bodies are small and easy to grip.
上記従来技術のように、送風機は載置して使用する場合と手に持って使用する場合があり、何れの場合でも安定した状態で使用し易いことが望まれていた。また、載置して使用する場合には、広域に送風することが望ましく、一方、手に持って使用する場合には、狭い範囲に強く送風することが望ましい。このため、載置して使用する送風機では、送風機構を左右に旋回させるような首振りや、羽根の形状等を工夫することで風を拡散して送風していた。また、手に持って使用する送風機では、羽根の形状等を工夫することで風を拡散させないように送風していた。 As in the above-mentioned prior art, the blower may be used while being placed or held in the hand, and it has been desired that the blower be stable and easy to use in either case. Further, when the device is used while being placed, it is desirable to blow air over a wide area, whereas when it is held in the hand, it is desirable to blow air strongly into a narrow area. For this reason, in the case of a blower that is used while mounted, the air is diffused by swinging the blower mechanism from side to side or by changing the shape of the blades. In addition, in hand-held blowers, the shape of the blades has been modified to prevent the air from spreading.
しかしながら、載置及び手に持つことの両方で使用するものにあっては、それぞれの使用状態に応じて風を広域に送風する或いは狭い範囲に送風することが求められ、首振りや羽根の形状等を工夫するだけでは充分に対応することができなかった。 However, for devices that are used both on a table and in the hand, it is necessary to blow air over a wide area or into a narrow area depending on the usage condition, and the swing of the head and the shape of the blades are required. It was not possible to deal with the problem sufficiently by simply devising methods such as the following.
本発明が解決しようとする課題は、上記従来技術の問題点を解決し、簡易な構造で、載置した場合に広い範囲に送風し、手に持った場合に狭い範囲に送風することが可能な送風機を提供することにある。 The problem to be solved by the present invention is to solve the above-mentioned problems of the prior art, and with a simple structure, it is possible to blow air over a wide area when placed on the table, and to blow air into a narrow area when held in the hand. Our goal is to provide a blower with a high quality.
本発明の送風機は、送風する送風機構と、該送風機構を駆動する駆動部と、前記送風機構及び駆動部を収めたケースと、を備え、前記ケースは、前記送風機構を収める先端部と、該先端部の後端から背後に延びる把持部からなり、該先端部の先端の位置に複数の送風孔を有する平坦な載置部を備えるとともに、前記送風機構及び前記載置部の周囲を囲う位置に複数の送風孔を有する側壁部を備えている。
The blower of the present invention includes a blower mechanism that blows air, a drive section that drives the blower mechanism, and a case that houses the blower mechanism and the drive section, and the case has a distal end section that houses the blower mechanism; It consists of a gripping part extending rearward from the rear end of the distal end, and includes a flat mounting part having a plurality of air blowing holes at the tip of the distal end, and the surroundings of the blowing mechanism and the mounting part. It is provided with a side wall portion having a plurality of ventilation holes at enclosing positions.
この送風機における前記送風機構は、同一の回転軸に関して相反する方向に回転する第１及び第２のインペラを備え、前記載置部は、第１及び第２のインペラの回転軸の延伸方向に位置するものとなっている。また、前記ケースは、前記送風機構と駆動部との間に発光制御部を有し、該発光制御部に前記載置部の方向に向かって発光する発光部を備えている。また、前記送風機構は、前記駆動部により前記第１及び第２のインペラを回転制御することにより回転軸方向への直進送風の増加と周囲へ広がる広域送風の増加とが切換駆動され、前記載置部を卓上に載置することにより該載置部に有する複数の送風孔が塞がれることによって広域送風の増加に切り換わるものとなっている。
The blower mechanism in this blower includes first and second impellers that rotate in opposite directions about the same rotation axis, and the mounting portion is located in the extending direction of the rotation axis of the first and second impellers. It has become something to do. Further, the case has a light emission control section between the blower mechanism and the drive section, and the light emission control section includes a light emission section that emits light toward the mounting section. Further, the blowing mechanism is configured to be driven to switch between increasing the straight air blowing in the direction of the rotation axis and increasing the wide area blowing air spreading to the surroundings by controlling the rotation of the first and second impellers by the driving section, and the above-mentioned By placing the placing part on a tabletop , the plurality of air blowing holes in the placing part are closed, thereby switching to an increase in air blowing over a wide area.
本発明の送風機は、送風機構に対面するケースの載置部を机上等に載置することで、載置部に設けられた送風孔が塞がれる。これにより、送風機構が送り出す風は、送風孔が塞がれた載置部に当たって径方向に広がり、載置部を囲む側壁部の送風孔から外方へ向かって流れだす。その結果、送風機は、広範囲に送風することになる。また、送風機を手に持つと、載置部の送風孔が開放され、送風機構からの風は載置部の送風孔から外方へ向かって流れることになる。その結果、送風機は、狭い範囲に送風することになる。このように、本発明の送風機では、簡易な構造で、載置した場合に広い範囲に送風し、手に持った場合に狭い範囲に送風することが可能となる。 In the blower of the present invention, by placing the mounting portion of the case facing the blowing mechanism on a desk or the like, the air blowing hole provided in the mounting portion is closed. As a result, the air sent out by the blowing mechanism spreads in the radial direction when it hits the mounting section where the ventilation holes are closed, and flows outward from the ventilation holes in the side wall portion surrounding the mounting section. As a result, the blower will blow air over a wide area. Furthermore, when the blower is held in the hand, the ventilation holes of the mounting section are opened, and the air from the ventilation mechanism flows outward from the ventilation holes of the mounting section. As a result, the blower blows air into a narrow area. As described above, the blower of the present invention has a simple structure and can blow air over a wide area when placed on the device, and blow air over a narrow area when held in the hand.
また、この送風機における送風機構は、同一の回転軸に関して相反する方向に回転する第1及び第２のインペラを備えており、その回転を制御することで送風の直進と広がりを切換可能としている。これにより、送風機を載置したときに、広い範囲に送風する状態に自動で切り換えると共に、送風機を手に持った状態であっても、送風を広い範囲と狭い範囲に切り換えることが可能となる。 In addition, the blowing mechanism in this blower includes first and second impellers that rotate in opposite directions about the same rotation axis, and by controlling the rotation of the impellers, it is possible to switch between straight forward and spreading air. As a result, when the blower is placed, it is automatically switched to a state where air is blown over a wide range, and even when the blower is held in hand, it is possible to switch between a wide range and a narrow range.
また、発光部を送風機構と駆動部との間に設けているので、手に持った場合だけでなく、載置した場合にも、送風機構周囲の側壁部に設けられた送風孔から外方に光が照射される。これにより、送風機を載置した場合にも、その周囲を照明することができる。 In addition, since the light emitting part is provided between the blower mechanism and the drive part, it will not only be possible to hold it in your hand, but also when it is placed on the ground, it will be visible from the outside through the ventilation hole provided in the side wall around the blower mechanism. light is irradiated on. Thereby, even when the blower is placed, the surrounding area can be illuminated.

A light emission control section 5 is provided.
ケース１は、送風機構２を収める円錐台形状をなす先端部１ａと、先端部１ａの後端から背後に延びる円筒形状の把持部１ｂとからなる。先端部１ａは、その先端の端面に円形で平坦な載置部１ｃを有し、その載置部１ｃの周囲に傾斜した周状の側壁部１ｄを有している。載置部１ｃには、放射状に形成された複数のスリットからなる送風孔１ｅが設けられている。また、側壁部１ｄには、把持部１ｂから載置部１ｃに向かう軸方向に形成された複数のスリットからなる送風孔１ｆが設けられている。尚、本実施形態における送風孔１ｅ、１ｆはスリット状の長孔であるが、長孔だけでなく丸孔であっても良い。また、先端部１ａの内部中央には、発光制御部５の基板を貫いて載置部１ｃの方向へ延びる細長円柱状の支持部１ｇが設けられている。更に、載置部１ｃの内面中央には、支持部１ｇの先端に対峙する細長円柱状の支持部１ｈが設けられている。 The case 1 includes a truncated cone-shaped distal end portion 1a that accommodates the air blowing mechanism 2, and a cylindrical grip portion 1b extending rearward from the rear end of the distal end portion 1a. The distal end portion 1a has a circular and flat mounting portion 1c on the end face of the distal end, and has an inclined peripheral side wall portion 1d around the mounting portion 1c. The mounting portion 1c is provided with a ventilation hole 1e consisting of a plurality of radially formed slits. Further, the side wall portion 1d is provided with an air blowing hole 1f consisting of a plurality of slits formed in the axial direction from the gripping portion 1b toward the placing portion 1c. Although the ventilation holes 1e and 1f in this embodiment are long holes in the form of slits, they may be not only long holes but also round holes. Furthermore, an elongated cylindrical support portion 1g extending through the substrate of the light emission control portion 5 toward the mounting portion 1c is provided at the center of the interior of the tip portion 1a. Furthermore, an elongated cylindrical support part 1h is provided at the center of the inner surface of the mounting part 1c, facing the tip of the support part 1g.
送風機構２は、互いに相反する方向へ回転する第1及び第２のインペラ２ａ、２ｂと、この第1及び第２のインペラ２ａ、２ｂに組み込まれて第1及び第２のインペラ２ａ、２ｂをそれぞれ回転駆動する第１及び第２のモータ２ｃ、２ｄと、を備えている。第1及び第２のインペラ２ａ、２ｂは、円形カップ状のロータ部２ｅ、２ｆと、このロータ部２ｅ、２ｆの外側面から略放射状に突出形成された羽根２ｇ、２ｈと、からそれぞれ構成されている。また、第１及び第２のモータ２ｃ、２ｄは、ロータ部２ｅ、２ｆの内周部にそれぞれ取り付けられた磁石２ｉ、２ｊと、ロータ部２ｅ、２ｆをそれぞれ回動自在に支持するシャフト２ｋ、２ｍと、軸受け２ｎ、２ｐを介してシャフト２ｋ、２ｍにそれぞれ外嵌され且つ磁石２ｉ、２ｊにそれぞれ接近対面するステータ２ｑ、２ｒと、ステータ２ｑ，２ｒにそれぞれ接続されるモータ基板２ｓ、２ｔ、とを備えている。シャフト２ｋ、２ｍは、軸心が直線状に連なるように、ケース１に設けられた支持部１ｇ、１ｈによりそれぞれ支持されている。また、モータ基板２ｓ、２ｔは、それぞれケース１の支持部１ｇ、１ｈに面する側に配置され、支持部１ｇ、１ｈに沿って設けられた配線を介して駆動部３にそれぞれ接続されている。 The blower mechanism 2 includes first and second impellers 2a and 2b that rotate in opposite directions, and is built into the first and second impellers 2a and 2b to rotate the first and second impellers 2a and 2b. It includes first and second motors 2c and 2d that rotate, respectively. The first and second impellers 2a and 2b are respectively composed of circular cup-shaped rotor parts 2e and 2f, and blades 2g and 2h formed to protrude substantially radially from the outer surfaces of the rotor parts 2e and 2f. ing. The first and second motors 2c and 2d also include magnets 2i and 2j attached to the inner circumferences of the rotor parts 2e and 2f, respectively, and shafts 2k that rotatably support the rotor parts 2e and 2f, respectively. 2m, stators 2q and 2r that are fitted onto the shafts 2k and 2m via bearings 2n and 2p and closely face the magnets 2i and 2j, respectively; and motor boards 2s and 2t that are connected to the stators 2q and 2r, respectively. It is equipped with The shafts 2k and 2m are supported by support parts 1g and 1h provided in the case 1, respectively, so that their axes are linearly connected. Further, the motor boards 2s and 2t are arranged on the side facing the support parts 1g and 1h of the case 1, respectively, and are connected to the drive part 3 via wiring provided along the support parts 1g and 1h, respectively. .
駆動部３は、電池と駆動制御回路等からなり、パソコンのＵＳＢ端子等から電力を得て蓄電し、スイッチ８の操作に応じて第１及び第２のモータ２ｃ、２ｄに電力を供給して第１及び第２のインペラ２ａ、２ｂを回転駆動する。 The drive unit 3 consists of a battery, a drive control circuit, etc., obtains power from a USB terminal of a personal computer, stores the power, and supplies power to the first and second motors 2c and 2d according to the operation of the switch 8. The first and second impellers 2a and 2b are rotationally driven.
発光部４は、図２、図４及び図５に示すように、駆動部３と送風機構２との間に設けられた発光制御部５の基板に配置された複数の発光素子からなる。本実施形態における発光部４は、支持部１ｇを中心としてその周囲に周状に複数配置されている。この発光部４は、スイッチ８の操作に応じて点灯すると共に、発光制御部５により点灯状態が制御され、例えば、送風機構２の回転に対応して点灯が制御される。 As shown in FIGS. 2, 4, and 5, the light emitting unit 4 includes a plurality of light emitting elements arranged on a substrate of a light emission control unit 5 provided between the drive unit 3 and the blower mechanism 2. A plurality of light emitting parts 4 in this embodiment are arranged in a circumferential manner around the supporting part 1g. The light emitting unit 4 lights up in response to the operation of the switch 8, and its lighting state is controlled by the light emission control unit 5, for example, in response to the rotation of the ventilation mechanism 2.
尚、上記送風機構２では、第１及び第２のインペラ２ａ、２ｂをそれぞれ別々のモータで回転させているが、単一のモータでそれぞれ回転させることも可能である。 In the above-described air blowing mechanism 2, the first and second impellers 2a and 2b are rotated by separate motors, but it is also possible to rotate each by a single motor.
上記構成からなる本実施形態の送風機では、スイッチ８の操作で駆動部３から第１及び第２のモータ２ｃ、２ｄに電力が供給され、第１及び第２のモータ２ｃ、２ｄが作動すると、第１及び第２のインペラ２ａ、２ｂが互いに反対の方向に回転駆動される。これにより、第１のインペラ２ａが発生させた風は、第２のインペラ２ｂによって直進性が高められる。このように直進性が高められた風は、第１及び第２のインペラ２ａ、２ｂに対面する載置部１ｃの送風孔１ｅから外方へ送出される。このため、把持部１ｂを手に持って、所望の方向に載置部１ｃを向けると、その方向に集中して風が送風される。 In the blower of this embodiment having the above configuration, power is supplied from the drive unit 3 to the first and second motors 2c and 2d by operating the switch 8, and when the first and second motors 2c and 2d are activated, The first and second impellers 2a, 2b are driven to rotate in opposite directions. Thereby, the straightness of the wind generated by the first impeller 2a is improved by the second impeller 2b. The wind whose straightness has been improved in this way is sent outward from the ventilation hole 1e of the mounting portion 1c facing the first and second impellers 2a and 2b. Therefore, when the holding part 1b is held in the hand and the mounting part 1c is directed in a desired direction, the air is blown in a concentrated manner in that direction.
また、この送風機を、図６に示すように、載置部１ｃが机上等に当接するように載置すると、載置部１ｃの送風孔１ｅは塞がれる。そのため、第１及び第２のインペラ２ａ、２ｂの回転で生じた風は載置部１ｃと机等の面にぶつかって径方向へ分散し、側壁部１ｄの送風孔１ｆから放射状に分散して送風される。 Further, as shown in FIG. 6, when this blower is placed so that the placing part 1c is in contact with a desk top or the like, the blowing hole 1e of the placing part 1c is closed. Therefore, the wind generated by the rotation of the first and second impellers 2a and 2b collides with the mounting part 1c and the surface of the desk, etc., and is dispersed in the radial direction. Air is blown.
上記のように、本実施形態における送風機では、手に持つことで直進性の高い狭い範囲への送風を行い、机上等に置くことで分散した広い範囲への送風を行うことができる。また、第１及び第２のインペラ２ａ、２ｂの回転差を変更することで送風の直進性を落とすことも可能である。その場合には、より広範囲に送風することが可能となる。尚、載置部１ｃの外面にスイッチあるいはセンサー等を設けることで、送風機を載置した場合にそれを検出し、第１及び第２のインペラ２ａ、２ｂの回転差を変更するように構成することも可能である。 As described above, the blower according to the present embodiment can blow air in a narrow area with high straightness by holding it in the hand, and can blow air in a dispersed manner over a wide area by placing it on a desk or the like. Furthermore, by changing the rotational difference between the first and second impellers 2a and 2b, it is also possible to reduce the straightness of the air blowing. In that case, it becomes possible to blow air over a wider area. In addition, by providing a switch or a sensor on the outer surface of the mounting portion 1c, it is configured to detect when a blower is mounted and change the rotation difference between the first and second impellers 2a and 2b. It is also possible.
また、発光部４を発光させると、載置部１ｃの送風孔１ｅと側壁部１ｄの送風孔１ｆから光が外方に照射される。ここで、発光部４の発光を第１及び第２のインペラ２ａ、２ｂの回転に同期させて、第１及び第２のインペラ２ａ、２ｂの羽根の合間から光が直接外方に照射するときだけ発光部４を発光させることで、照明効果を下げることなく発光部４の消費電力を少なくすることが可能となる。 Moreover, when the light emitting part 4 is made to emit light, light is radiated outward from the ventilation hole 1e of the mounting part 1c and the ventilation hole 1f of the side wall part 1d. Here, when the light emission of the light emitting unit 4 is synchronized with the rotation of the first and second impellers 2a and 2b, and light is directly irradiated outward from between the blades of the first and second impellers 2a and 2b. By causing the light emitting section 4 to emit light by only the amount of light emitting light, it is possible to reduce the power consumption of the light emitting section 4 without reducing the illumination effect.
尚、第１及び第２のインペラ２ａ、２ｂとして透光性を有する材質のものを用いれば、第１及び第２のインペラ２ａ、２ｂが発光部４からの光を遮ることはなくなる。 Note that if the first and second impellers 2a and 2b are made of a translucent material, the first and second impellers 2a and 2b will not block the light from the light emitting part 4.
また、ケース１の載置部１ｃ等に香を放つ芳香部品を取り付けるか、あるいは送風機を安定して載置するために載置部１ｃを載せる台等を設け、その台等に芳香部品を取り付けることで、香りのついた風を送風することが可能となる。 In addition, an aromatic component that emits a scent may be attached to the mounting section 1c of the case 1, or a stand or the like is provided on which the mounting section 1c is placed in order to stably place the blower, and the aromatic component is attached to the platform. This makes it possible to blow scented air.
また、送風機を載せる台等を設けた場合、その台等を、非接触給電を行う給電部材とすることもできる。更にその場合に、給電中の送風を、直進性を落とした風に自動で切り換えるように設定することもできる。 Further, when a stand or the like on which the blower is placed is provided, the stand or the like can also be used as a power supply member that performs non-contact power supply. Furthermore, in that case, it is also possible to set the air flow during power supply to be automatically switched to a flow that reduces straightness.
次に、第２実施形態における送風機は、図７及び図８に示すように、第１実施形態における第２のインペラ２ｂを削減して第１のインペラ２ａだけで送風を行うように構成されている。これにより、第２実施形態における送風機では、第１実施形態に比べると、特段直進性の高い風を送風するものではなく、風の直進性を２つのインペラの回転差で変更するものでもないが、第１のインペラ２ａの背後に配置された発光部４からの光を、載置部１ｃの送風孔１ｅから外方に向かって放出し易い状態にすることができる。尚、その他の構成に関しては、第１実施形態と同一であり、詳細な説明は省略する。 Next, as shown in FIGS. 7 and 8, the blower in the second embodiment is configured to remove the second impeller 2b in the first embodiment and blow air only with the first impeller 2a. There is. As a result, compared to the first embodiment, the blower in the second embodiment does not blow air with particularly high straightness, and does not change the straightness of the wind by the difference in rotation between the two impellers. , the light from the light emitting section 4 disposed behind the first impeller 2a can be easily emitted outward from the ventilation hole 1e of the mounting section 1c. Note that the other configurations are the same as those in the first embodiment, and detailed explanations will be omitted.
この第２実施形態における送風機では、送風機構２のインペラが第１のインペラ２ａだけであることから、この第１のインペラ２ａの回転周期と発光部４の点灯周期を同期させることが容易な構成となる。この送風機では、例えば、図４及び図９に示すように、第１のインペラ２ａの羽根２ｇが等間隔で５枚設けられており、その背後に設けられている発光部４も同様に周上に等間隔で５個設けられている。このため、図９に示すように、第１のインペラ２ａの羽根２ｇが発光部４の前を通過すると、羽根２ｇの間から発光部４が載置部１ｃに対面する。この時点で発光部４を点灯させ、図１０に示すように、発光部４が羽根２ｇに対面したときに消灯するように、発光部４の点灯を同期制御することにより、発光による電力消費を抑え、効率良く照明することができる。 In the blower according to the second embodiment, since the impeller of the blower mechanism 2 is only the first impeller 2a, the rotation period of the first impeller 2a and the lighting period of the light emitting unit 4 can be easily synchronized. becomes. In this blower, for example, as shown in FIGS. 4 and 9, five blades 2g of the first impeller 2a are provided at equal intervals, and the light emitting part 4 provided behind the blades is also provided on the circumference. 5 are provided at equal intervals. Therefore, as shown in FIG. 9, when the blades 2g of the first impeller 2a pass in front of the light emitting part 4, the light emitting part 4 faces the mounting part 1c from between the blades 2g. At this point, the light emitting part 4 is turned on, and as shown in FIG. 10, the power consumption due to light emission is reduced by synchronously controlling the lighting of the light emitting part 4 so that it turns off when the light emitting part 4 faces the blade 2g. It can be controlled and efficiently illuminated.
上記のように、羽根２ｇの回転周期と発光部４の点灯周期を同期制御するには、羽根２ｇの位置を検出することが必要になる。羽根２ｇの位置を検出するには、例えば、シャフト２ｋに図示しない回転板等を取り付け、その回転板等に羽根２ｇに対応する貫通孔を設け、その貫通孔を介して対面する発光素子と受光素子からなる検出手段を設けることで、羽根２ｇの位置を示す検出信号を得ることができる。この検出信号に基づいて発光制御部５が発光部４を断続的に点灯させることで、羽根２ｇの回転周期と発光部４の点灯周期を同期させることができる。 As described above, in order to synchronously control the rotation period of the blade 2g and the lighting period of the light emitting section 4, it is necessary to detect the position of the blade 2g. To detect the position of the blade 2g, for example, a rotating plate (not shown) is attached to the shaft 2k, a through hole corresponding to the blade 2g is provided in the rotating plate, and light is received by a light emitting element facing through the through hole. By providing a detection means consisting of an element, a detection signal indicating the position of the blade 2g can be obtained. Based on this detection signal, the light emission control section 5 lights up the light emitting section 4 intermittently, so that the rotation period of the blade 2g and the lighting period of the light emitting section 4 can be synchronized.
上記のように、羽根２ｇの回転周期と発光部４の点灯周期を同期させることができると、同期を制御することで、様々な発光状態を作り出すことができる。例えば、ゾエトロープの原理に基づいて、互いに関連付けられた画像、例えば徐々に態様が変化する絵等を複数の羽根２ｇにそれぞれ設け、その回転に同期させて発光部４を点灯させることで羽根２ｇに効果的に光を当てる。これにより、羽根２ｇに設けられた画像は変化するように見え、動きを伴った様々な変化を演出することが可能となる。 As described above, if the rotation period of the blade 2g and the lighting period of the light emitting section 4 can be synchronized, various light emission states can be created by controlling the synchronization. For example, based on the principle of a zoetrope, images associated with each other, such as pictures whose appearance gradually changes, are provided on each of a plurality of blades 2g, and the light emitting unit 4 is turned on in synchronization with the rotation of the blades 2g. Shine light effectively. As a result, the image provided on the blade 2g appears to change, making it possible to produce various changes accompanied by movement.
また、載置部１ｃや側壁部１ｄの内面に反射板あるいは反射層を設けるか、送風機を載置させるための台に反射板等を設けることで、送風孔１ｅ、１ｆから外方に向かう光を増加させて効率を高め、より明るく周囲を照明することが可能となる。 In addition, by providing a reflective plate or a reflective layer on the inner surface of the placing part 1c and the side wall part 1d, or by providing a reflective plate or the like on the stand on which the blower is placed, light directed outward from the air blowing holes 1e and 1f can be prevented. This makes it possible to increase efficiency and illuminate the surrounding area more brightly.
また、載置用の台を非接触給電を行う給電部材とし、給電中における発光部４の点灯を、羽根２ｇの間で点灯し羽根２ｇに対面するときに消灯する周期で点灯するように自動で切り換えるように設定することもできる。 In addition, the mounting table is used as a power supply member that performs non-contact power supply, and the light emitting part 4 is automatically turned on during power supply so that it lights up between the blades 2g and turns off when facing the blades 2g. You can also set it to switch.
