Description

【０００１】
【発明の属する技術分野】
本発明は、壁掛け式の空気調和機に係わり、より詳細には、暖房運転時に室温分布の均一化をはかることができ、且つ室内の乾燥を防止することができ、また、ドライ運転時に室温をあまり下げずに除湿できるようにした構造に関する。
【０００２】
【従来の技術】
従来の壁掛け式の空気調和機は、例えば特開平１１ー２０１４８８号公報に記載されているように、本体の上部を仕切壁により前後に区画し、仕切壁後方の本体上面に第１の吸込口と、本体前面中央部に第２の吸込口を設け、第２の吸込口の下方に第１の吹出口を、上方に第２の吹出口を設け、第１の吸込口を臨ませて第１の室内熱交換器を設け、第１の室内熱交換器の下部に第１の送風ファンを設け、第２の吸込口に臨ませて第２の室内熱交換器を設け、第１の室内熱交換器の下部に第１の露受皿を設け、第２の室内熱交換器の下部に第２の露受皿を設け、第１の吹出口に回動自在に第２の風向板を設けた構成となっていた。
【０００３】
すなわち、暖房運転時に前記第２の室内熱交換器が蒸発器として作用し、発生した凝縮水は前記第２の露受皿で受けられた後、水路により前記第１の室内熱交換器の下部熱交換器の前面側に導かれ、前記第１の吹出口から水分が室内に戻され、室内の乾燥を防止するようになっている。
【０００４】
しかしながら、上記公報に添付された図で示すように、前記凝縮水が、前記第１の室内熱交換器の下部熱交換器の下端部の前面側に導かれ、前記第１の吹出口から水分が室内に戻され、室内の乾燥を防止する構成であって、前記第１の室内熱交換器のの下部熱交換器全体に前記凝縮水が導かれる状態ではないことから、前記第１の吹出口から水分を室内に戻すための効率は必ずしもよくなかった。
【０００５】
また、前記第１の室内熱交換器および前記第２の室内熱交換器は、上記の機能を達成するために多くの折曲部を有した複雑な形状になっており、コスト的に不利な構成となっていた。
【０００６】
【発明が解決しようとする課題】
本発明は、上記問題点を解決して、コスト的に有利なシンプルな構成により、暖房運転時に送出される温風の乾燥感をなくして目、喉および肌などが乾かないようにすると共に、この温風が上昇し天井付近が暖かくなって不快感を感じてしまうということがないようにした壁掛け式の空気調和機を提供することを目的としている。
【０００７】
【課題を解決するための手段】
本発明は、上記の課題を解決するため、本体の前面上部および上面に設けられた吸込口と、下面に設けられた吹出口と、これら吸込口と吹出口とを結ぶ空気通路に設けられ、同空気通路および前記吹出口を前後に区画した仕切体と、同仕切体の上部に設けられ、前後に区画された第一空気通路と第二空気通路とを連通する連通孔と、前後に区画された第一吹出口および第二吹出口に夫々設けられた第一上下風向板および第二上下風向板と、前記第一空気通路に設けられ、垂直部と、同垂直部の上端を後方に折曲した後方傾斜部とで断面く字状に形成された第一熱交換器および第一送風ファンと、前記後方傾斜部の後方に略平行に離間させ、前記第二空気通路に設けられた第二熱交換器および第二送風ファンと、前記後方傾斜部の上部と前記第二熱交換器の上部との間に架設された遮風板とで構成され、
暖房運転時に、前記第一熱交換器の垂直部を加熱加湿器とし、前記後方傾斜部を冷却器とし、前記第二熱交換器を再熱器として、前記前面上部の吸込口から吸い込み、前記第一熱交換器の垂直部を通して加湿された温風を前記第一吹出口から吹き出すようにし、前記前面上部の吸込口から吸い込み、前記第一熱交換器の後方傾斜部を通したのち、前記連通孔から前記第二熱交換器を通して除湿された空気を前記第二吹出口から吹き出すようにした構成となっている。
【０００８】
また、前記遮風板は、少なくともその一部が前記上面の吸込口と、前記第二熱交換器との間を開閉する開閉体を備えた構成となっている。
【０００９】
また、前記開閉体に、駆動モータが連係された構成となっている。
【００１０】
また、前記第一上下風向板を下方に回動して、前記第一吹出口から加湿温風を前方下部に向けて吹き出した際、前記第二上下風向板を略垂直位置に回動して、前記第二吹出口から除湿空気を直下に向けて吹き出すようにした構成となっている。
【００１１】
更に、前記第二熱交換器が、前記第一熱交換器の後方傾斜部よりも少許上位に配置され、前記第二送風ファンが、前記第一送風ファンよりも少許上位に配置された構成となっている。
【００１２】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいた実施例として詳細に説明する。
図１は本発明による空気調和機の断面図であり、図２は本発明による空気調和機の冷凍サイクルを示す図である。
【００１３】
本発明による壁掛け式の空気調和機は、図１で示すように、本体の前面上部および上面には吸込口１が設けられ、下面には吹出口が設けられると共に、これら吸込口１と吹出口とを結ぶ空気通路は、上部に連通孔８を備えた仕切体９により前後に区画されて第一吹出口３に連なる空気通路６と、第二吹出口５に連なる第二空気通路７とが夫々形成されている。
【００１４】
前記第一吹出口３には、第一上下風向板２が回動自在に軸支され、前記第二吹出口５には、第二上下風向板４が回動自在に軸支されている。
【００１５】
前記第一空気通路６には、下部に第一露受皿3bを備えた垂直部10a と、同垂直部10a の上端を後方に折曲した後方傾斜部10b とで断面く字状に形成された第一熱交換器10と、第一送風ファン11とが風上側から順に設けられ、前記第二空気通路７には、前記後方傾斜部10b の後方に略平行に離間させた第二熱交換器12と、第二送風ファン13とが風上側から順に設けられている。
【００１６】
前記第一吹出口３の上面には、前記第一露受皿3bが設けられると共に、前記第一送風ファン11に対応する第一スタビライザ3aが設けられる一方、前記仕切体９には、前記第二送風ファン13に対応する第一スタビライザ9aと、前記第二熱交換器12の下部に対応する第二露受皿9bが設けられている。
【００１７】
前記後方傾斜部10b の上部と、前記第二熱交換器12の上部との間には、駆動モータ16が連係され前記本体上面の吸込口１と前記第二熱交換器12との間を開閉する開閉体15を備えた遮風板14が架設されている。
【００１８】
ここで、図２に基づいて冷凍サイクルの構成を説明する。
本発明による空気調和機の冷凍サイクルは、圧縮機ａと、四方弁ｂと、室外熱交換器ｃと、第一膨張弁ｄと、前記第一熱交換器10の後方傾斜部10b と、第二膨張弁ｅと、並列にした前記第一熱交換器10の垂直部10a および前記第二熱交換器12とが順次配管接続された構成となっている。
【００１９】
以上の構成により、次にその動作について説明する。
暖房運転時に、前記第一膨張弁ｄが全開され、前記第二膨張弁ｅが絞られ、前記第一熱交換器10の垂直部10a を加熱加湿器とし、前記後方傾斜部10b を冷却器とし、前記第二熱交換器12を再熱器として、図１の矢印で示す空気流Ａのように、前記前面上部の吸込口１から吸い込み前記第一熱交換器10の垂直部10a を通して加湿された温風を前記第一吹出口３から吹き出すようにし、矢印で示す空気流Ｂのように、前記前面上部の吸込口１から吸い込み、前記第一熱交換器10の後方傾斜部10b を通したのち、前記連通孔８から前記第二熱交換器12を通して除湿された空気を前記第二吹出口５から吹き出すようにしている。
【００２０】
これによって、冷却器とした前記第一熱交換器10の後方傾斜部10b で結露した水分が、加熱加湿器とした前記第一熱交換器10の垂直部10a に導かれることによって蒸発し、同垂直部10a で暖められた空気といっしょに、前記空気流Ａのように、前記第一吹出口３から加熱加湿された空気として室内に送出されるようになる。
【００２１】
その際、前記第一熱交換器10の後方傾斜部10b で結露した水分は、前記垂直部10a の上部から流下することから、水分を効率よく蒸発させることができるようになる。
【００２２】
また同時に、冷却器とした前記第一熱交換器10の後方傾斜部10b で除湿冷却された空気が、前記連通孔８から再熱器とした前記第二熱交換器12に導かれることによって暖められるようになり、前記空気流Ｂのように、除湿され室温と同程度に暖められた空気が、加熱加湿された前記空気流Ａの下層部に向け、前記第二吹出口５から、とくに人のいない室内の窓や壁に沿わせて送出されるようになっている。
【００２３】
すなわち、前記第一上下風向板２を下方に回動して、前記第一吹出口３から加湿温風を前方下部に向けて吹き出した際、前記第二上下風向板４を略垂直位置に回動して、前記第二吹出口５から除湿空気を直下に向けて吹き出すようにした構成となっているので、温風が届かない場所では足元が寒く、天井付近では暖気が溜まって不快感を感じさせてしまうといったことがなくなる。
【００２４】
また、前記第二熱交換器12が、前記第一熱交換器10の後方傾斜部10b よりも少許上位に配置され、前記第二送風ファン13が、前記第一送風ファン11よりも少許上位に配置された構成となっているので、例えばこれら第二送風ファン13および第一送風ファン11が同じ高さで配置されている場合に対し、気調和機を薄型化できることになる。
【００２５】
なお、前記遮風板14は、前記駆動モータ16が連係された開閉体15を備えた構成となっているので、例えば暖房運転時には、上記に説明のとおり、前記駆動モータ16で前記開閉体15を自動的に閉じることによって効果的な空気加湿を行えるようになり、また冷房運転時には、前記開閉体15を自動的に開くことによって、前記上面の吸込口１から吸い込まれた空気を熱交換して効果的に冷気を生成できるようになる。
【００２６】
【発明の効果】
以上説明したように、本発明によると、コスト的に有利なシンプルな構成により、暖房運転時に送出される温風の乾燥感をなくして目、喉および肌などが乾かないようにすると共に、この温風が上昇し天井付近が暖かくなって不快感を感じてしまうということがないようにした壁掛け式の空気調和機となる。

Hereinafter, embodiments of the present invention will be described in detail as examples based on the drawings.
FIG. 1 is a sectional view of an air conditioner according to the present invention, and FIG. 2 is a diagram showing a refrigeration cycle of the air conditioner according to the present invention.
[0013]
As shown in FIG. 1, the wall-mounted air conditioner according to the present invention is provided with a suction port 1 on the front upper surface and upper surface of the main body and a blower outlet on the lower surface, and these suction port 1 and blower outlet. The air passage connecting the air outlet 6 is divided into a front and rear by a partition 9 having a communication hole 8 in the upper part, and an air passage 6 connected to the first air outlet 3 and a second air passage 7 connected to the second air outlet 5. Each is formed.
[0014]
A first up-and-down wind direction plate 2 is pivotally supported by the first air outlet 3, and a second up-and-down air direction plate 4 is rotatably supported by the second air outlet 5.
[0015]
The first air passage 6 is formed in a cross-sectional shape with a vertical portion 10a having a first dew tray 3b at a lower portion and a rear inclined portion 10b bent at the upper end of the vertical portion 10a rearward. A first heat exchanger 10 and a first blower fan 11 are provided in order from the windward side, and a second heat exchanger is provided in the second air passage 7 so as to be spaced substantially parallel behind the rear inclined portion 10b. 12 and a second blower fan 13 are provided in order from the windward side.
[0016]
The upper surface of the first air outlet 3 is provided with the first dew receiving tray 3b and a first stabilizer 3a corresponding to the first blower fan 11, while the partition body 9 has the second A first stabilizer 9a corresponding to the blower fan 13 and a second dew tray 9b corresponding to the lower part of the second heat exchanger 12 are provided.
[0017]
A drive motor 16 is linked between the upper portion of the rear inclined portion 10b and the upper portion of the second heat exchanger 12, and opens and closes between the suction port 1 on the upper surface of the main body and the second heat exchanger 12. A wind shielding plate 14 having an opening / closing body 15 is installed.
[0018]
Here, the configuration of the refrigeration cycle will be described with reference to FIG.
The refrigeration cycle of the air conditioner according to the present invention includes a compressor a, a four-way valve b, an outdoor heat exchanger c, a first expansion valve d, a rear inclined portion 10b of the first heat exchanger 10, The two expansion valve e, the vertical portion 10a of the first heat exchanger 10 and the second heat exchanger 12 that are arranged in parallel are sequentially connected by piping.
[0019]
Next, the operation of the above configuration will be described.
During the heating operation, the first expansion valve d is fully opened, the second expansion valve e is throttled, the vertical portion 10a of the first heat exchanger 10 is a heating humidifier, and the rear inclined portion 10b is a cooler. Then, using the second heat exchanger 12 as a reheater, the air is sucked from the suction port 1 at the upper front and is humidified through the vertical portion 10a of the first heat exchanger 10 as shown by the air flow A shown by the arrow in FIG. The warm air is blown out from the first air outlet 3 and is sucked in from the air inlet 1 at the top of the front surface as shown by an arrow B and passes through the rear inclined portion 10b of the first heat exchanger 10. After that, dehumidified air is blown out from the second air outlet 5 through the communication hole 8 through the second heat exchanger 12.
[0020]
As a result, moisture condensed at the rear inclined portion 10b of the first heat exchanger 10 serving as a cooler evaporates by being led to the vertical portion 10a of the first heat exchanger 10 serving as a heating humidifier. Together with the air heated in the vertical portion 10a, the air flow A is sent out into the room as heated and humidified air from the first air outlet 3 as in the air flow A.
[0021]
At this time, the moisture condensed in the rear inclined portion 10b of the first heat exchanger 10 flows down from the upper portion of the vertical portion 10a, so that the moisture can be efficiently evaporated.
[0022]
At the same time, the air dehumidified and cooled by the rear inclined portion 10b of the first heat exchanger 10 serving as a cooler is warmed by being led from the communication hole 8 to the second heat exchanger 12 serving as a reheater. The air that has been dehumidified and heated to about the same temperature as the room temperature is directed toward the lower layer of the heated and humidified air stream A from the second air outlet 5, It is sent along a window or wall in the room without a window.
[0023]
That is, when the first up-and-down air direction plate 2 is rotated downward and the humidified warm air is blown out from the first air outlet 3 toward the front lower part, the second up-and-down air direction plate 4 is rotated to a substantially vertical position. The dehumidified air is blown out directly from the second air outlet 5 so that the feet are cold when hot air does not reach, and warm air accumulates near the ceiling, causing discomfort. You don't feel like it.
[0024]
In addition, the second heat exchanger 12 is arranged at a lower level than the rear inclined portion 10b of the first heat exchanger 10, and the second blower fan 13 is placed at a lower level than the first blower fan 11. Since the arrangement is such that the air conditioner can be made thinner than when the second blower fan 13 and the first blower fan 11 are arranged at the same height, for example.
[0025]
The wind shield 14 is configured to include an opening / closing body 15 to which the drive motor 16 is linked. Therefore, for example, during heating operation, the opening / closing body 15 is driven by the drive motor 16 as described above. By automatically closing, the air can be effectively humidified, and during the cooling operation, the opening / closing body 15 is automatically opened to exchange heat from the air suction port 1 on the upper surface. And cool air can be generated effectively.
[0026]
【The invention's effect】
As described above, according to the present invention, the simple structure advantageous in terms of cost eliminates the feeling of dryness of the warm air sent out during the heating operation, and prevents the eyes, throat, skin, and the like from being dried. This is a wall-mounted air conditioner that prevents the warm air from rising and the vicinity of the ceiling from becoming warm and uncomfortable.
