室の床下を二重床とし、床全面に設けた吹出し孔から空調空気を微速にて室内に吹き出す全面床吹出し空調システムは、ドラフト感（空調機から吹き出される空調空気が直接人体に当たることによる不快感）がなく、快適な空調環境を実現することができる（例えば、特許文献１参照）。
しかし、この全面床吹出し空調システムでは、床全面からほぼ同温度かつ同風速の空調空気が吹き出されるため、過度な局所負荷には対応できないという問題がある。 The floor floor air-conditioning system that blows conditioned air into the room at a very low speed from the blow holes provided on the entire floor of the floor under the floor of the room is a draft feeling (due to the fact that the conditioned air blown from the air conditioner directly hits the human body. A comfortable air-conditioning environment can be realized (for example, see Patent Document 1).
However, this entire floor blowing air conditioning system has a problem in that it cannot cope with an excessive local load because conditioned air having substantially the same temperature and the same wind speed is blown out from the entire floor surface.

そこで、特許文献２では、吹出風量が調節可能とされたスポット吹出装置を床の所定箇所に設けた全面床吹出し方式空調設備が提案されている。
特開平６−２２９５８４号公報 特開平８−１５２１５８号公報 Therefore, Patent Document 2 proposes a full-surface floor blowing type air conditioning system in which a spot blowing device in which the amount of blown air is adjustable is provided at a predetermined location on the floor.

しかしながら、特許文献２に記載された全面床吹出し方式空調設備の場合、スポット吹出装置の設置位置が固定されるため、将来のレイアウト変更に対応できないという問題がある。   However, in the case of the full-surface floor blowing type air conditioner described in Patent Document 2, since the installation position of the spot blowing device is fixed, there is a problem that it cannot cope with future layout changes.

本発明は、上述する問題点に鑑みてなされたもので、将来のレイアウト変更に伴う局所負荷の変動に対応できる全面床吹出し空調システムを実現することを目的とする。   The present invention has been made in view of the above-described problems, and an object of the present invention is to realize a full-floor blow-out air conditioning system that can cope with fluctuations in local loads accompanying future layout changes.

上記目的を達成するため、本発明は、全面床吹出し空調システムにおいて使用される送風機であって、室の床下に形成された給気通路を自律走行する枠体内に、水平面内で回転する羽根部および当該羽根部を駆動する駆動部と、当該駆動部に前記羽根部を駆動するように指示する制御部とを備えることを特徴とする。
本発明では、送風機が室の床下に形成された給気通路を自律走行し、当該給気通路から集中的に送風を行うので、将来のレイアウト変更に伴う局所負荷の変動に対しても容易に対応することができる。 In order to achieve the above-mentioned object, the present invention is a blower used in a full-floor air-conditioning system, and is a blade that rotates in a horizontal plane in a frame that autonomously travels through an air supply passage formed under the floor of the room. And a drive unit that drives the blade unit, and a control unit that instructs the drive unit to drive the blade unit.

本発明によれば、送風機が室の床下に形成された給気通路を自律走行し、当該給気通路から集中的に送風を行うので、将来のレイアウト変更に伴う局所負荷の変動に対しても容易に対応することができる。   According to the present invention, the blower autonomously travels in the air supply passage formed under the floor of the room and intensively blows air from the air supply passage. It can be easily handled.

以下、本発明の実施形態について図面に基づいて説明する。
図１および図２に本発明に係る送風機の構成を示す。
本送風機１は、枠体２の中心部に有圧換気扇３を固定し、有圧換気扇３の羽根車３ａ（羽根部）を水平面内で回転させるようにしたものである。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show the configuration of the blower according to the present invention.
The blower 1 is configured such that a pressure ventilation fan 3 is fixed to the center of a frame body 2 and an impeller 3a (blade part) of the pressure ventilation fan 3 is rotated in a horizontal plane.

有圧換気扇３は、モーター３ｂ（駆動部）の回転軸にプロペラ式の羽根車３ａを取付けたものであり、一般家庭用の換気扇に比べ、大風量、高静圧が得られる。   The pressure ventilation fan 3 has a propeller impeller 3a attached to the rotating shaft of a motor 3b (drive unit), and can obtain a larger air volume and a higher static pressure than a general household ventilation fan.

枠体２には、有圧換気扇３を取り囲むように周縁部に、平面視方形の側壁部５が形成されており、側壁部５から上方に出没可能な突出部５ａを側壁部５内に備えている。一方、枠体２の上下面は、空調空気を下面から取り込んで上面から吹き出せるように開口部となっている。   The frame body 2 is formed with a side wall portion 5 having a square shape in a plan view at the peripheral edge so as to surround the pressure ventilation fan 3. ing. On the other hand, the upper and lower surfaces of the frame 2 are openings so that conditioned air can be taken from the lower surface and blown out from the upper surface.

また、枠体２の底面には、支持脚６を介してローラー７が取り付けられており、図示しないローラー駆動部の動力により水平方向に自律走行することができる。そのため、室内に設置された温度センサの値を受信し、受信した温度センサの値に基いて枠体２を移動させ、有圧換気扇３を駆動するように指示する受信・制御部４と、電源部８が枠体２に装備されている。
なお、枠体２が二重床内を移動できるように、枠体２の外径寸法は二重床を支持する支持脚のピッチよりも小さくなっている。また、電源部８には、自動巻き取り式でストッパーの無い電源ケーブル８ａが装備されており、二重床内における電源ケーブル８ａの巻きつきを防止している。 Moreover, the roller 7 is attached to the bottom face of the frame 2 via the support leg 6, and can autonomously run in the horizontal direction by the power of a roller drive unit (not shown). Therefore, the receiving / control unit 4 that receives the value of the temperature sensor installed in the room, moves the frame body 2 based on the received value of the temperature sensor, and drives the pressure ventilation fan 3; The part 8 is mounted on the frame 2.
The outer diameter of the frame 2 is smaller than the pitch of the support legs that support the double floor so that the frame 2 can move in the double floor. Further, the power supply unit 8 is equipped with a power cable 8a that is an automatic winding type and has no stopper, and prevents the power cable 8a from being wound around the double floor.

次に、上記構成を有する本送風機１の動作について、図３の二重床部分の立断面図を用いて説明する。
室内は全面床吹出し空調とされており、二重床とされた床下が給気通路Ｖとして利用される。一方、天井には吸気口が設けられており、天井より上は還気通路として利用される。また、室に隣接して空調機械室が設けられており、空調機械室には空調機が設置されている。 Next, operation | movement of this air blower 1 which has the said structure is demonstrated using the elevation sectional drawing of the double floor part of FIG.
The interior of the room is a full-floor air-conditioning system, and the floor under the double floor is used as the air supply passage V. On the other hand, an air inlet is provided in the ceiling, and the ceiling is used as a return air passage. An air conditioner room is provided adjacent to the room, and an air conditioner is installed in the air conditioner room.

本床１１は、通気性ＯＡフロア９と、その上に敷きつめられた通気性タイルカーペット１０から構成されている。通気性ＯＡフロア９は、方形パネル（図示省略）の四隅を支持脚（図示省略）で支持する二重床構造となっており、均一に空気が滲み出すように、方形パネルには複数の孔が設けられている。また、通気性タイルカーペット１０は、表面材として従来のタイルカーペットと同素材を使用し、繊維で補強された通気繊維素材を裏打ち材に使用したものである。   The main floor 11 includes a breathable OA floor 9 and a breathable tile carpet 10 laid on the floor. The breathable OA floor 9 has a double floor structure in which four corners of a square panel (not shown) are supported by support legs (not shown), and a plurality of holes are formed in the square panel so that air can ooze out uniformly. Is provided. The breathable tile carpet 10 uses the same material as a conventional tile carpet as a surface material, and uses a breathable fiber material reinforced with fibers as a backing material.

室内の各所には温度センサ（図示省略）が設置されており、本送風機１に装備された受信・制御部４では、常時、温度センサの値を監視している。
所定値を超えた値を示す温度センサを検知すると、受信・制御部４は、予め登録された温度センサの情報から、所定値を超えた値を示す温度センサの位置情報を抽出し、給気通路Ｖ内を自律走行して、所定値を超えた値を示す温度センサの下方で停止する。
そして、側壁部５に格納されている突出部５ａを上方に突出させて通気性ＯＡフロア９に当接させ、羽根車３ａの風圧が側方に逃げるのを防止した後、有圧換気扇３を作動させ、熱負荷の大きい箇所に対して下方から集中的に送風する。これにより、所定値を超えた値を示す温度センサの位置における空調空気Ｗは、他の箇所の空調空気Ｗ０よりも給気圧力が高くなり、温度ムラが解消される。 Temperature sensors (not shown) are installed at various locations in the room, and the value of the temperature sensor is constantly monitored by the reception / control unit 4 provided in the blower 1.
When detecting the temperature sensor indicating the value exceeding the predetermined value, the reception / control unit 4 extracts the position information of the temperature sensor indicating the value exceeding the predetermined value from the information of the temperature sensor registered in advance, It autonomously travels in the passage V and stops below the temperature sensor that indicates a value exceeding a predetermined value.
Then, the protruding portion 5a stored in the side wall portion 5 is protruded upward and brought into contact with the breathable OA floor 9 to prevent the wind pressure of the impeller 3a from escaping to the side, and then the pressure ventilation fan 3 is Operate and blow air intensively from below to places with high heat load. As a result, the conditioned air W at the position of the temperature sensor that indicates a value exceeding the predetermined value has a higher air supply pressure than the conditioned air W 0 at other locations, and temperature unevenness is eliminated.

本実施形態による送風機では、室内に設置された温度センサの値に基いて、送風機１が室の床下に形成された給気通路Ｖを移動し、熱負荷の大きい箇所に対して集中的に送風を行うので、将来のレイアウト変更に伴う局所負荷の変動に対しても容易に対応することができる。   In the blower according to the present embodiment, the blower 1 moves in the air supply passage V formed under the floor of the room based on the value of the temperature sensor installed in the room, and blows air intensively to a place with a large heat load. Therefore, it is possible to easily cope with a change in local load accompanying a layout change in the future.

なお、比較的狭い空間でインテリアとペリメータが分離しにくい空間では、本送風機１をペリメータに集中的に配置し、暖房空気をペリメータに集中させることで快適な空調空間を提供できる。また、このことにより、ぺリカウンター内ファンコイルユニットなどを必要としない自由度の高い空間を提供できる。   In a relatively narrow space where it is difficult to separate the interior and the perimeter, a comfortable air-conditioned space can be provided by intensively arranging the blower 1 on the perimeter and concentrating the heating air on the perimeter. In addition, this makes it possible to provide a highly flexible space that does not require a fan coil unit in the pericounter.

以上、本発明の実施形態について説明したが、本発明は上記の実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。例えば、上記の実施形態では、枠体を平面視方形としているが、平面視円形でもよい。
また、上記の実施形態では、送風機はローラーを装備し、ローラーによる移動としているが、給気通路にレールを設置し、送風機がレール上を移動するようにしてもよい。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit thereof. For example, in the above embodiment, the frame is a square in plan view, but may be circular in plan view.
In the above embodiment, the blower is equipped with a roller and moved by the roller. However, a rail may be installed in the air supply passage so that the blower moves on the rail.
