図4、5において、従来の床置型空気調和機の本体100の前面部には、上部より吹き出しグリル101と、中部の前面パネル102と、下部の吸入グリル103が設けられており、下部の吸入グリル103より吸込んだ空気を、上部の吹き出しグリル101より室内に吹出す構成となっている。   4 and 5, a blow grill 101, a middle front panel 102, and a lower suction grill 103 are provided on the front portion of a main body 100 of a conventional floor-mounted air conditioner, and a lower suction grill 103 is provided. The air sucked from the grill 103 is blown out into the room from the upper blowing grill 101.

又、本体100は、側板104、105と、天板106と、底板107と、後ろ板108で骨格を形成している。   The main body 100 forms a skeleton with side plates 104 and 105, a top plate 106, a bottom plate 107, and a back plate 108.

しかしながら、上記従来の床置型空気調和機の構造では以下のような課題を有していた。   However, the structure of the conventional floor-mounted air conditioner has the following problems.

高さに制約がある床置型空気調和機の本体100では、その高さによって収納できる室内熱交換器114の高さが決定されてしまうため、冷暖房性能を向上させるためには本体110のサイズを高くするか横幅を大きくせざるを得なかった。   Since the height of the indoor heat exchanger 114 that can be stored is determined by the height of the main body 100 of the floor-type air conditioner with a restriction on the height, the size of the main body 110 is reduced in order to improve the air conditioning performance. I had to increase it or increase the width.

また、冷暖房性能に大きく影響を及ぼす風回路構成において、室内熱交換器114は、その長さを最大とするために傾斜させて収納されており、送風機111はその下方に設けられていた。   Further, in the wind circuit configuration that greatly affects the cooling and heating performance, the indoor heat exchanger 114 is housed in an inclined manner in order to maximize the length thereof, and the blower 111 is provided therebelow.

そしてこの構成上、送風機111より吹出した室内空気は、室内熱交換器114に下方から斜めに吹き付けられる。   In this configuration, the indoor air blown from the blower 111 is blown obliquely from below to the indoor heat exchanger 114.

このような構成では、空気はもっぱら本体100の背面側の壁面に沿って流れる傾向が強く、室内熱交換器114の上部の風速分布は大きく、下部の風速分布は小さくなってしまい、室内熱交換器114を通過する風速分布が全体として不均一な状態となり、室内熱交換器114の性能を最大限発揮する構成になっていなかった。   In such a configuration, the air tends to flow exclusively along the wall surface on the back side of the main body 100, the wind speed distribution in the upper part of the indoor heat exchanger 114 is large, the wind speed distribution in the lower part is reduced, and indoor heat exchange is performed. The wind speed distribution passing through the heat exchanger 114 becomes non-uniform as a whole, and the configuration of the indoor heat exchanger 114 is not maximized.

また、室内熱交換器114の各部分における風速分布が異なるため、室内熱交換器114を通過した空気の温度が不均一となり、吹出し口の周囲への結露の発生を惹起し、最悪の場合は成長した結露水が吹出されて室内に飛散し、クレームになるといった課題があった。   In addition, since the wind speed distribution in each part of the indoor heat exchanger 114 is different, the temperature of the air that has passed through the indoor heat exchanger 114 becomes non-uniform, causing dew condensation around the outlet, and in the worst case There was a problem that the condensed water that had grown was blown out and scattered into the room, resulting in a complaint.

本発明は、上記従来の課題を解決するもので、室内熱交換器への風速分布をより均一にし、熱交換性能を向上させ、冷暖房性能を向上させた床置型空気調和機を提供することを目的とする。   The present invention solves the above-described conventional problems, and provides a floor-mounted air conditioner in which the wind speed distribution to the indoor heat exchanger is made more uniform, the heat exchange performance is improved, and the air conditioning performance is improved. Objective.

前記従来の課題を解決するために、本発明の床置型空気調和機は、本体前面下方に設けた吸入グリルと、前記本体前面上方に設けた吹き出しグリルと、前記吸入グリルと前記吹き出しグリルとを結ぶ風回路内に配され、室内空気を前記吸入グリルから吸引し、前記吹き出しグリルから吹出す送風機と、前記風回路内に配され吸引された空気を熱交換する室内熱交換器と、前記送風機の風下側で、かつ前記室内熱交換器の風上側に設けられ前記送風機が吹出した空気の方向を制御する整流板と、前記整流板の傾斜角度を変える駆動機構とを備えたもので、整流板を傾斜させて、収納された室内熱交換器の風速分布を改善することで、室内熱交換器の能力を増大させ、冷暖房能力を向上させることができる。     In order to solve the above-described conventional problems, a floor-mounted air conditioner according to the present invention includes a suction grill provided below the front of the main body, a blow grill provided above the front of the main body, the suction grill, and the blow grill. A blower that is arranged in a connecting wind circuit and sucks indoor air from the suction grille and blows out from the blowout grill; an indoor heat exchanger that exchanges heat in the sucked air that is arranged in the wind circuit; and the blower A rectifying plate that is provided on the leeward side of the indoor heat exchanger and that controls the direction of the air blown out by the blower, and a drive mechanism that changes the inclination angle of the rectifying plate. By tilting the plate and improving the wind speed distribution of the housed indoor heat exchanger, the capacity of the indoor heat exchanger can be increased and the cooling and heating capacity can be improved.

本発明の床置型空気調和機は、室内熱交換器への風速分布をより均一にし、熱交換性能を向上させ、冷暖房性能を向上させることができる。   The floor-mounted air conditioner of the present invention can make the air velocity distribution to the indoor heat exchanger more uniform, improve the heat exchange performance, and improve the air conditioning performance.

第1の発明は、本体前面下方に設けた吸入グリルと、前記本体前面上方に設けた吹き出しグリルと、前記吸入グリルと前記吹き出しグリルとを結ぶ風回路内に配され、室内空気を前記吸入グリルから吸引し、前記吹き出しグリルから吹出す送風機と、前記風回路内に配され吸引された空気を熱交換する室内熱交換器と、前記送風機の風下側で、かつ前記室内熱交換器の風上側に設けられ前記送風機が吹出した空気の方向を制御する整流板と、前記整流板の傾斜角度を変える駆動機構とを備えたもので、整流板を傾斜させて、収納された室内熱交換器の風速分布を改善することで、室内熱交換器の能力を増大させ、冷暖房能力を向上させることができる。   According to a first aspect of the present invention, a suction grill provided below the front surface of the main body, a blowing grill provided above the front surface of the main body, and a wind circuit connecting the suction grill and the blowing grill, A blower that is sucked out from the blowout grill, an indoor heat exchanger that heat-exchanges the sucked air disposed in the wind circuit, a leeward side of the blower, and an upwind side of the indoor heat exchanger Provided with a rectifying plate that controls the direction of the air blown out by the blower, and a drive mechanism that changes the inclination angle of the rectifying plate. By improving the wind speed distribution, the capacity of the indoor heat exchanger can be increased and the cooling / heating capacity can be improved.

整流板の傾斜角度を変化させ、室内熱交換器に向けて吹付ける空気の角度を一様に変化させるもので、送風機の回転数により異なる風速分布に対応して室内熱交換器に吹付ける空気の角度を変更することにより、より均一な風速分布で室内空気を室内熱交換器に吹付けることができるため、送風機の全使用回転数領域で、最適な風速分布を実現でき、室内熱交換器の能力を増大させ、冷暖房能力に優れた床置型空気調和機を提供することができるものである。
According to the third aspect of the invention, in particular, the angle of the air blown toward the indoor heat exchanger is changed by changing the inclination angle of the rectifying plate by the drive mechanism in accordance with the rotational speed of the blower of the first or second aspect. By changing the angle of the air blown to the indoor heat exchanger in response to the different wind speed distribution depending on the rotation speed of the blower, the indoor air is blown to the indoor heat exchanger with a more uniform wind speed distribution. Therefore, it is possible to provide an optimal air velocity distribution in the entire range of rotation speed of the blower, increase the capacity of the indoor heat exchanger, and provide a floor-mounted air conditioner with excellent air conditioning capability. It is.

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。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, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 is an exploded perspective view of a main body of a floor-mounted air conditioner according to Embodiment 1 of the present invention, FIG. 2 is a cross-sectional view of the main body, and FIG. 3 is a detailed enlarged cross-sectional view of part A in FIG. .

図1〜3において、1は、吹出しグリル、2は、前面パネル、3は吸入グリルであり、この3点の部品によって、本実施の形態における床置型空気調和機の本体20の前面が構成されている。   1-3, 1 is a blow-out grill, 2 is a front panel, 3 is a suction grille, and the front of the main body 20 of the floor type air conditioner in the present embodiment is constituted by these three parts. ing.

又本体20自体は、側版5、6ならびに天板4、前板7、底板15、後ろ板8で骨格を構成しており、この骨格内部に、ファンモーター10およびエアガイダー9ならびにオリフィス12を具備した送風機11を配置し、前板7の上に電源板13が取付けられて全体が構成されている。19は、吹出しグリル1と吸入グリル3を結ぶ風回路である。   The main body 20 itself has a skeleton composed of the side plates 5 and 6 and the top plate 4, the front plate 7, the bottom plate 15, and the rear plate 8, and the fan motor 10, the air guider 9 and the orifice 12 are provided inside the skeleton. The blower 11 is arranged, and a power supply plate 13 is attached on the front plate 7 to constitute the whole. Reference numeral 19 denotes a wind circuit connecting the blow-out grill 1 and the suction grill 3.

さらにエアガイダー9の上方すなわち下流側に位置する吹き出し部9aの背面側に回動可能な整流板16と、整流板16を回動駆動する駆動機構である駆動用モーター17が取り付けられており、最大風量時に送風機11より吹き出された室内空気の流れを制御して、よりよい角度で室内熱交換器14に吹付けて、室内熱交換器14への風速分布をよりよく制御するようにしている。   Further, a rotatable rectifying plate 16 and a driving motor 17 which is a driving mechanism for rotating the rectifying plate 16 are attached to the upper side of the air guider 9, that is, on the back side of the blowing portion 9a located on the downstream side. The flow of the room air blown from the blower 11 at the time of the air volume is controlled and blown to the indoor heat exchanger 14 at a better angle, so that the wind speed distribution to the indoor heat exchanger 14 is better controlled.

吹付けられる室内空気の風速分布を室内熱交換器14にとってよりよくすることで、室内熱交換器14の性能を向上させる構成となっている。   The performance of the indoor heat exchanger 14 is improved by improving the wind speed distribution of the indoor air to be blown to the indoor heat exchanger 14.

整流板16の先端部Bは、図3に示すように室内熱交換器14側に湾曲した形状となっており、吹き出した室内空気の流れを意図した角度に曲げやすい形状となっている。   As shown in FIG. 3, the front end B of the rectifying plate 16 has a shape curved toward the indoor heat exchanger 14, so that the flow of the blown indoor air is easily bent to an intended angle.

このように構成された床置型空気調和機の風回路19では、もっぱら本体20の背面側の壁面に沿って吹出された空気が流れる傾向があるため、風回路19の背面側が前面側に比べて空気の速度分布が大きくなっている。このため、室内熱交換器14の上部に吹付けられる空気の速度は大きく、室内熱交換器14の下部に吹付けられる空気の速度は小さくなり、室内熱交換器14全体としての風速分布は不均一なものになる傾向があり、これは送風機11から吹出す風速が大きいほど顕著である。   In the wind circuit 19 of the floor-type air conditioner configured as described above, the air blown out tends to flow exclusively along the wall surface on the back side of the main body 20, so that the back side of the wind circuit 19 is compared to the front side. The air velocity distribution is large. For this reason, the speed of the air blown to the upper part of the indoor heat exchanger 14 is high, the speed of the air blown to the lower part of the indoor heat exchanger 14 is reduced, and the wind speed distribution as a whole of the indoor heat exchanger 14 is not good. There exists a tendency which becomes uniform, and this is so remarkable that the wind speed which blows off from the air blower 11 is large.

そこで、本実施の形態では、駆動用モーター17で、整流板16の傾斜角α°を送風機11の回転数に応じて変化させるようにしたもので、具体的には、送風機11の回転数が低いときにはα°を小さく、送風機11の回転数が大きくなるにしたがってα°を大きくしていくように一様に変化させ、風量変更に対しても室内熱交換器14に吹付ける角度をよりよく制御する。   Therefore, in the present embodiment, the drive motor 17 is configured to change the inclination angle α ° of the rectifying plate 16 in accordance with the rotational speed of the blower 11. Specifically, the rotational speed of the blower 11 is When α is low, α ° is reduced, and α ° is uniformly increased so as to increase as the rotational speed of the blower 11 increases, and the angle of blowing to the indoor heat exchanger 14 is improved even when the air volume is changed. Control.

以上のように本実施の形態によれば、よりよい風速分布をなすように、整流板16を制御するため、常に室内熱交換器14の熱交換効率を最適に保ち、風回路性能を向上させる
ことができると同時に、室内熱交換器14で熱交換された空気の温度が均一になり、結果、吹出しグリル1への結露を防止できるため、室内側への結露水の飛散を防止することができ、実使用上の品質をも向上することができる。
As described above, according to the present embodiment, since the rectifying plate 16 is controlled so as to achieve a better wind speed distribution, the heat exchange efficiency of the indoor heat exchanger 14 is always kept optimal, and the wind circuit performance is improved. At the same time, the temperature of the air heat-exchanged by the indoor heat exchanger 14 becomes uniform, and as a result, it is possible to prevent dew condensation on the blow-out grill 1, thereby preventing the dew condensation from splashing indoors. And the quality in practical use can be improved.

以上のように、本発明にかかる床置型空気調和機は、本体サイズを変更することなしに風回路の中に整流板と駆動用モーターを設けることで、常に室内熱交換器の熱交換効率を最適に保つことができ、風回路性能を向上させることができ、さらに吹出しグリルへの結露も防止できるので、同様の風回路を具備する除湿機や空気清浄機等の用途にも適用できる。   As described above, the floor-mounted air conditioner according to the present invention always improves the heat exchange efficiency of the indoor heat exchanger by providing the rectifying plate and the driving motor in the wind circuit without changing the main body size. Since it can be kept optimal, wind circuit performance can be improved, and condensation on the blowout grill can be prevented, it can be applied to applications such as dehumidifiers and air purifiers having similar wind circuits.
