Abstract
Description
本発明は空気調和機に関し、特に室内ユニットに関するものである。 The present invention relates to an air conditioner, and more particularly to an indoor unit.
空気調和機の室内ユニットでは、送風機によって誘引することで室内空気を空気吸込み口から吸込み、これを熱交換器での熱交換によって温度調節をした後、空調風として空気吹き出し口から室内へ吹き出すようになっている。従来、この種の空気調和機の室内ユニットは、風向偏向時に室内ユニットの吹き出し口に配置されている風向偏向板を大きく回転させ風向偏向方向への風の向きを変えている（例えば、特許文献１参照）。 In an indoor unit of an air conditioner, indoor air is sucked from an air suction port by being attracted by a blower, and after adjusting the temperature by heat exchange in a heat exchanger, the air is blown out from the air outlet to the room It has become. Conventionally, an indoor unit of this type of air conditioner changes the direction of the wind in the direction of the wind direction by largely rotating a wind direction deflecting plate arranged at the outlet of the indoor unit when the direction of the wind is deflected (for example, Patent Documents). 1).
図７は、特許文献１に記載された従来の空気調和機の室内ユニットの略断面図を示すものである。図７に示すように、室内ユニット１に熱交換器２が架設され、吸込み口３から送風機４により吸い込まれた空気は熱交換器２を通して熱交換され、吹き出し口７から吹き出される。形状記憶合金で形成された風向偏向板８を変形させることで吹き出し気流を自在に向けたい方向へ向けている。このため風向偏向板が必要な時のみ風を曲げる適度な曲げ形状となるため通風抵抗となって著しい風量低下を招くことなく風向偏向が可能となっている。 FIG. 7 is a schematic sectional view of an indoor unit of a conventional air conditioner described in Patent Document 1. As shown in FIG. 7, the heat exchanger 2 is installed in the indoor unit 1, and the air sucked by the blower 4 from the suction port 3 is heat-exchanged through the heat exchanger 2 and blown out from the blowout port 7. By deforming the wind direction deflecting plate 8 formed of a shape memory alloy, the blown airflow is directed in a desired direction. For this reason, since it becomes an appropriate bending shape that bends the wind only when the wind direction deflecting plate is necessary, it is possible to deflect the wind direction without causing a significant decrease in the air flow due to the ventilation resistance.
しかしながら、前記従来の構成では、形状記憶合金に常時電圧印加しなければならないという課題を有していた。 However, the conventional configuration has a problem that a voltage must be constantly applied to the shape memory alloy.
本発明は、前記従来の課題を解決するもので、空気調和機の室内ユニットにおいて、電圧を印加することによって反り変形をする高分子シートで風向偏向板の風上側任意長さを構成しその部分の風向偏向時のみ電圧印加することで曲率半径を変え風向偏向板自身が風路を塞ぎ通風抵抗の増加を招くことを防止でき、また常時電圧印加の不要な空気調和機の室内ユニットを提供することを目的とする。 The present invention solves the above-mentioned conventional problems. In an indoor unit of an air conditioner, a polymer sheet that warps and deforms by applying a voltage constitutes an arbitrary length on the windward side of a wind direction deflector. By applying a voltage only when the wind direction is deflected, the radius of curvature can be changed to prevent the wind direction deflecting plate itself from blocking the wind path and causing an increase in ventilation resistance, and an indoor unit of an air conditioner that does not require voltage application at all times is provided. For the purpose.
前記従来の課題を解決するために、本発明の空気調和機の室内ユニットは、電圧を印加することによって反り変形をする高分子シートで風向偏向板の風上側任意長さを構成し、風向偏向板の曲率半径を変えることで風向偏向板の風上側のみを風上に向けることで風向偏向板自身が風路を塞ぎ通風抵抗の増加を招くことを防止可能とする。 In order to solve the above-mentioned conventional problems, the indoor unit of the air conditioner of the present invention comprises a polymer sheet that is warped and deformed by applying a voltage, and has an arbitrary length on the windward side of the wind direction deflecting plate. By changing the radius of curvature of the plate, only the windward side of the wind direction deflecting plate is directed to the wind side, so that it is possible to prevent the wind direction deflecting plate itself from blocking the wind path and increasing the draft resistance.
本発明の空気調和機の室内ユニットは、風向偏向板自身が風路を塞ぎ通風抵抗の増加を招くことを防止できるため、製品の高性能化による省エネ貢献や製品の小型が実現でき、製品設置可能箇所の拡大などを図ることができる。 The indoor unit of the air conditioner of the present invention can prevent the wind direction deflecting plate itself from blocking the air path and causing an increase in ventilation resistance. The possible locations can be expanded.

第２の発明は、高分子シートが電圧を印加することで反り変形をする性状をもつイオン伝導性高分子素子で構成されたことを特徴とするもので、電圧を印加するだけで反り変形を起すことができ、制御が容易である。 The second invention is characterized in that the polymer sheet is composed of an ion conductive polymer element having a property of warping and deforming when a voltage is applied. Can be woken up and easy to control.

第４の発明は、可動シートを反り変形させる時のみ高分子シートに電圧が印加される構成であることを特徴とするもので、変形後の保持期間は電圧を印加する必要がなく、常時電圧印加を必要とするような場合に比して消費電力が少なくてすみ、省エネ性に優れた運転が可能である。 The fourth invention is characterized in that a voltage is applied to the polymer sheet only when the movable sheet is warped and deformed, and it is not necessary to apply a voltage during the holding period after deformation, and the voltage is always applied.

以下、本発明の各実施の形態を図１〜図６に基づいて説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, each embodiment of the present invention will be described with reference to FIGS. Note that the present invention is not limited to the embodiments.
（実施の形態１）
図１は、本発明の第１の実施の形態における空気調和機の室内ユニットの略断面図を示したものである。図１において、室内ユニット１内に配置された熱交換器２と送風機４によって、室内に冷媒のエネルギーを供給する。吹き出し口７の中に電圧を印加することによって風上側任意長さのみが下方へ変形する高分子シート可動風向偏向板８‘を配置した構成となっている。
(Embodiment 1)
FIG. 1 is a schematic cross-sectional view of an indoor unit of an air conditioner according to a first embodiment of the present invention. In FIG. 1, the energy of the refrigerant is supplied into the room by a heat exchanger 2 and a blower 4 arranged in the indoor unit 1. A polymer sheet movable wind direction deflecting plate 8 ′ in which only an arbitrary length on the windward side is deformed downward by applying a voltage in the outlet 7 is arranged.
ここで、高分子シート可動風向偏向板８‘について詳細に説明する。図２は高分子シート可動風向偏向板８‘の構成断面図、図３は高分子シート可動風向偏向板８‘の平面図、図４は高分子シート可動風向偏向板８‘の動作説明図、図５は可動シートの断面模式図、図６はイオン伝導性高分子素子による高分子シートの動作を説明する断面図である。図５において、高分子シート可動風向偏向板８‘は、電圧の印加によって反り変形を発生する
高分子シート１１を複数枚積層し、且つ、これを弾性樹脂材１８で被包することによって形成される。この高分子シート１１は図６（ｂ）に示すように、水分を含むイオン伝導性高分子素子１２の両面にそれぞれ電極１３（ａ），（ｂ）を配置して構成された板状部材であって、電極１３（ａ）と電極１３（ｂ）とを、極性切り替えスイッチ１４を介して直流電源１５に接続し、極性切り替えスイッチ１４の切り替え操作によって、電極１３（ａ），（ｂ）の極性を適宣変更することで図６（ａ），（ｃ）に示すように反対方向に反り変形を生じるものである。
Here, the polymer sheet movable wind direction deflecting plate 8 ′ will be described in detail. FIG. 2 is a structural sectional view of the polymer sheet movable wind direction deflecting plate 8 ′, FIG. 3 is a plan view of the polymer sheet movable wind direction deflecting plate 8 ′, and FIG. FIG. 5 is a schematic sectional view of the movable sheet, and FIG. 6 is a sectional view for explaining the operation of the polymer sheet by the ion conductive polymer element. In FIG. 5, the polymer sheet movable wind direction deflecting plate 8 ′ is formed by laminating a plurality of polymer sheets 11 that generate warp deformation when a voltage is applied, and encapsulating them with an elastic resin material 18. The As shown in FIG. 6B, the polymer sheet 11 is a plate-like member configured by disposing electrodes 13 (a) and (b) on both surfaces of an ion conductive polymer element 12 containing moisture. The electrodes 13 (a) and 13 (b) are connected to the DC power supply 15 via the polarity changeover switch 14, and the polarity changeover switch 14 is operated to switch the electrodes 13 (a) and (b). By appropriately changing the polarity, warping deformation occurs in the opposite direction as shown in FIGS.
具体的には、図６（ａ）に示す様に、電極１３（ａ）を「陽極」に、電極１３（ｂ）を「陰極」に設定すると、イオン伝導性高分子素子１２内の「陽イオン１６」が水を伴って「陰極」側へ移動し、含水量が「陰極」側に偏在し、「陰極」側と「陽極」側との間に膨潤差が生じて高分子シート１１が「陰極」側、即ち、電極１３（ｂ）側へ凸状に反り変形するものである。逆に図６（ｃ）に示すように電極１３（ａ）を「陰極」に、電極１３（ｂ）を「陽極」に設定すると、「陰極」である電極１３（ａ）側へ凸状に反り変形するものである。この様に電圧印加の極性を変更することで高分子シート１１を反り変形させることができるものである。 Specifically, as shown in FIG. 6A, when the electrode 13 (a) is set to “anode” and the electrode 13 (b) is set to “cathode”, the “positive” in the ion conductive polymer element 12 is set. The ions 16 move to the “cathode” side with water, the water content is unevenly distributed to the “cathode” side, and a swelling difference occurs between the “cathode” side and the “anode” side, so that the polymer sheet 11 is formed. It is warped and deformed in a convex shape toward the “cathode” side, that is, the electrode 13 (b) side. Conversely, as shown in FIG. 6 (c), when the electrode 13 (a) is set to “cathode” and the electrode 13 (b) is set to “anode”, it protrudes toward the electrode 13 (a) which is the “cathode”. It warps and deforms. In this way, the polymer sheet 11 can be warped and deformed by changing the polarity of voltage application.
尚、イオン伝導性高分子素子１２には、電圧印加によって反り変形させた後、電圧印加をなくしても、電圧印加停止前の反り変形状態をそのまま維持するという性状をもっている。したがって、このイオン伝導性高分子素子１２はこれを反り変形させる時にのみ電圧印加を行えば良いものである。元通りに戻すには両電極１３（ａ），（ｂ）を短絡すれば良い。 It should be noted that the ion conductive polymer element 12 has a property that, after being warped and deformed by voltage application, the warped deformation state before stopping the voltage application is maintained as it is even if the voltage application is not performed. Therefore, it is only necessary to apply a voltage to the ion conductive polymer element 12 only when it is warped and deformed. To return to the original state, both electrodes 13 (a) and (b) may be short-circuited.
上記の構成とすることで、機器の運転状態や室内の空気状態に応じて、高分子シート可動風向偏向板８‘の高分子シート１１に電圧を印加し、反り変形を発生させることで、高分子シート可動風向偏向板８‘の風上側のみを風上に向けることで風向偏向板自身が風路を塞ぎ通風抵抗の増加を招くことを防止できるため、風量増加による高性能化を実現させることができる。また、小型化による製品のダウンサイジングが実現でき、製品設置可能箇所の拡大などを図ることができる。また常時電圧印加が不要であるため省エネに貢献出来る。 By adopting the above-described configuration, a voltage is applied to the polymer sheet 11 of the polymer sheet movable wind direction deflecting plate 8 ′ in accordance with the operation state of the device and the air condition in the room, thereby generating warp deformation. Since only the windward side of the molecular sheet movable wind direction deflecting plate 8 'is directed toward the wind side, the wind direction deflecting plate itself can be prevented from blocking the wind path and causing an increase in draft resistance, so that high performance can be realized by increasing the air volume. Can do. In addition, downsizing of the product can be realized by downsizing, and the number of places where the product can be installed can be increased. Moreover, it is possible to contribute to energy saving because it is not necessary to always apply voltage.
以上のように、本発明にかかる空気調和機の室内ユニットは、風向偏向板の風上側のみを風上に向けることにより風向偏向板が通風抵抗とならず大風量化が実現出来、高性能化できるものである。 As described above, the indoor unit of the air conditioner according to the present invention can realize a large air volume by making only the windward side of the wind direction deflector plate face the windward, so that the wind direction deflector plate does not become a draft resistance and can achieve high performance. It can be done.
