Description

この発明は空気調和機、特に、前面上下に吹き出し口を有する空気調和機の室内機に関する。   The present invention relates to an air conditioner, and more particularly, to an indoor unit of an air conditioner having outlets on the upper and lower sides of a front surface.

従来、室内の温度や湿度を快適に維持するため、上下に吹き出し口を具備した空気調和機が開示されている（例えば、特許文献１参照）。
また、上下に吹き出す風の風量が互いに干渉しないように、上ファンと下ファンとの間に仕切板を設置した発明が開示されている（例えば、特許文献２参照）。
さらに、上部ファンと下部ファンとの回転数に差を設けた場合でも、風流れが安定するように、上部ファンと下部ファンとの間の仕切板を移動自在にした発明が開示されている（例えば、特許文献３参照）。 Conventionally, in order to maintain indoor temperature and humidity comfortably, an air conditioner having upper and lower outlets has been disclosed (see, for example, Patent Document 1).
Further, an invention is disclosed in which a partition plate is installed between the upper fan and the lower fan so that the amounts of winds blown up and down do not interfere with each other (see, for example, Patent Document 2).
Furthermore, an invention is disclosed in which the partition plate between the upper fan and the lower fan is movable so that the wind flow is stable even when there is a difference in the rotational speed between the upper fan and the lower fan ( For example, see Patent Document 3).

実開昭５５−６７９３４号公報（第３−４頁、第３図）Japanese Utility Model Publication No. 55-67934 (page 3-4, Fig. 3) 特開昭６１−１５３４２６号公報（第２頁、第１図）JP 61-153426 (2nd page, Fig. 1) 特開平８−１７８３３８号公報（第３頁、第２図）JP-A-8-178338 (page 3, FIG. 2)

しかしながら、特許文献１〜３に開示された発明は、上側送風機（上ファン、上部ファン）および下側送風機（下ファン、下部ファン）の能力が発揮されず、また、騒音が出るという問題があった。
すなわち、特許文献１に開示された発明は、上側送風機と下側送風機との間に前面に向かって断面山状に突出するセパレータを有し、吸引する空気を上下に分流させるものであるため、該セパレータの裾野と上側送風機および下側送風機との間（吸込側に同じ）に、所定の範囲にわたる所定の隙間が確保されないため、気流が乱れ風速を増すことができない。 However, the inventions disclosed in Patent Documents 1 to 3 have a problem that the upper blower (upper fan, upper fan) and the lower blower (lower fan, lower fan) do not exhibit their ability and noise is generated. It was.
That is, the invention disclosed in Patent Document 1 has a separator protruding in a mountain-shaped cross section toward the front surface between the upper blower and the lower blower, and diverts the air to be sucked up and down. Since a predetermined gap over a predetermined range is not ensured between the base of the separator and the upper and lower fans (same as the suction side), the air current is disturbed and the wind speed cannot be increased.

また、特許文献２に開示された発明は、平面状の背面に仕切板を立設しただけのものであるため、仕切板の周囲で吸引する空気に淀や乱れが生じると共に、上ファンおよび下ファンの吸込側に所定の範囲にわたる所定の隙間が確保されないため、気流が乱れ風速を増すことができない。
さらに、特許文献３に開示された発明は、移動自在な仕切板を設置しているため、そのための移動機構を必要とし、部品点数の増大や重量の増加、さらには故障等による保全性の悪化と共に、仕切板の移動範囲を確保するために、上部ファンおよび下部ファンの吸込側に所定の範囲にわたる所定の隙間が確保されないため、気流が乱れ風速を増すことができない。 Further, since the invention disclosed in Patent Document 2 is only a partition plate provided upright on a flat back surface, air sucked around the partition plate is disturbed and turbulent, and the upper fan and lower Since a predetermined gap over a predetermined range is not secured on the suction side of the fan, the air current is disturbed and the wind speed cannot be increased.
Furthermore, since the invention disclosed in Patent Document 3 is provided with a movable partition plate, it requires a moving mechanism for that purpose, and increases the number of parts and weight, and further deteriorates maintainability due to a failure or the like. At the same time, since a predetermined gap over a predetermined range is not secured on the suction side of the upper fan and the lower fan in order to secure the moving range of the partition plate, the air current is disturbed and the wind speed cannot be increased.

この発明は、上記のような課題を解決するためになされたもので、簡素な構成であって、上方ファンおよび下方ファンのそれぞれに向かってなめらかに分流され、且つ、乱れが少なく風速の増した気流を形成するセパレータを具備する空気調和機を得ることを目的とする。合わせて、上吹き単独（上方ファンのみ運転して、下方ファンを停止する）でも風量が低下せず、低騒音な空気調和機を得ることを目的とする。   The present invention has been made in order to solve the above-described problems, has a simple configuration, smoothly diverts toward the upper fan and the lower fan, and has less turbulence and increased wind speed. It aims at obtaining the air conditioner which comprises the separator which forms airflow. In addition, an object is to obtain a low-noise air conditioner in which the air volume does not decrease even when the top blower is alone (only the upper fan is operated and the lower fan is stopped).

FIG. 1 is a longitudinal sectional view illustrating the configuration of an air conditioner according to Embodiment 1 of the present invention.
In FIG. 1, an indoor unit 100 of an air conditioner (not shown) has a housing 1, an upper outlet 3 at the upper part of the front surface (left side in the figure) of the casing 1, and a lower outlet 4 at the lower part. The upper air outlet 3 and the lower air outlet 4 are respectively provided with an upper air direction variable plate 5 and a lower air direction variable plate 6 that change the direction of the air flow. ing.
An upper cross-flow fan 9 and a lower cross-flow fan 10 that blow air toward the upper blow-out port 3 and the lower blow-out port 4 are installed inside the housing 1. The upper rear guider 14 and the lower rear guider 15 having a substantially arc-shaped cross section are respectively disposed.

そして、吸込口２に対峙して筐体１の内部に、熱交換器１３が配置され、熱交換器１３の上端縁には上吹出口３との間を仕切るための上吹出ノズル７と、熱交換器１３の下端縁には下吹出口４との間を仕切るための下吹出ノズル８と、が配設されている。
さらに、熱交換器１３の背面側（図中、右側）には波形セパレータ１２が設置されている。波形セパレータ１２は断面略Ｗ字状であって、断面中央部で前面に向かって略円弧状に突出する中央山部（以下「コブ」と称す）１２ｃと、コブ１２ｃの上方および下方のそれぞれになめらかに連なり、背面に向かって略円弧状に凹陥する上方谷部１２ｂおよび下方谷部１２ｄを具備している。そして、上方リアガイダ１４の下端縁１４ａと波状セパレータ１２の上方谷部１２ｂの上端縁１２ａとが接続され、下方リアガイダ１５の上端縁１５ａと波状セパレータ１２の下方谷部１２ｄの下端縁１２ｅとが接続されている。 And the heat exchanger 13 is arrange | positioned inside the housing | casing 1 facing the suction inlet 2, The upper blowing nozzle 7 for partitioning between the upper blower outlets 3 at the upper end edge of the heat exchanger 13, At the lower end edge of the heat exchanger 13, a lower outlet nozzle 8 for partitioning from the lower outlet 4 is disposed.

Has been.

次に動作について説明する。
このように構成された空気調和機の室内機１００（上下２フローの室内機）において、室内の空気は上方貫流ファン９および下方貫流ファン１０に引かれることより吸込口２から吸い込まれ、熱交換器１３で熱交換された後、断面略円弧状のコブ１２ｃで上下に整流されながら分流される。そして、分流された気流はそれぞれ、上方谷部１２ｂおよび下方谷部１２ｄになめらかに案内されて上方貫流ファン９および下方貫流ファン１０に吸い込まれ、上方吹出口３および下方吹出口４からそれぞれ上方風向可変版５および下方風向可変版６で決められた角度でもって吹き出される。 Next, the operation will be described.
In the indoor unit 100 (upper and lower two-flow indoor unit) of the air conditioner configured as described above, indoor air is drawn from the suction port 2 by being drawn by the upper once-through fan 9 and the lower once-through fan 10, and heat exchange is performed. After the heat exchange is performed in the vessel 13, the current is diverted while being rectified up and down by the bump 12 c having a substantially arc-shaped cross section. The diverted airflows are respectively smoothly guided to the upper valley 12b and the lower valley 12d and sucked into the upper once-through fan 9 and the lower once-through fan 10, respectively. The air is blown at an angle determined by the variable plate 5 and the downward wind direction variable plate 6.

このとき、セパレータ１２は断面略円弧状の上方谷部１２ｂとコブ１２ｃと下方谷部１２ｄとがなめらかな曲線で結ばれて略Ｗ字状を呈し、上縁部１２ａおよび下縁部１２ｅが上方リアガイダ１４の下縁部１４ａおよび下方リアガイダ１５の上縁部１５ａにそれぞれ接合されているから、上方リアガイダ１４とセパレータ１２と下方リアガイダ１５とによって、波状（谷数が４）のケーシングが形成されている。したがって、前記分流時に気流の乱れはなく、低騒音な室内機１００が形成される。また、気流の乱れがなく、しかも上方リアガイダ１４および下方リアガイダ１５によって整流や増速が図られるため、風量がアップする。
さらに、上下分流用の仕切板等の移動機構を持たないため、簡素な構造であって、部品点数や重量の増加が防止され、製造コストが安価に維持されながら、信頼性の向上した空気調和機が得られる。 At this time, the separator 12 has an approximately valley shape in which the upper valley portion 12b, the bump 12c, and the lower valley portion 12d having a substantially arc-shaped cross section are connected by a smooth curve, and the upper edge portion 12a and the lower edge portion 12e are formed upward. Since the upper guider 14, the separator 12, and the lower rear guider 15 are joined to the lower edge portion 14 a of the rear guider 14 and the upper edge portion 15 a of the lower rear guider 15, a wavy casing (four valleys) is formed. Yes. Therefore, there is no turbulence of the airflow during the diversion, and the low-noise indoor unit 100 is formed. In addition, there is no turbulence in the air flow, and the upper rear guider 14 and the lower rear guider 15 perform rectification and acceleration, so the air volume increases.
In addition, since it does not have a moving mechanism such as a partition plate for vertical splitting, it has a simple structure, prevents an increase in the number of parts and weight, maintains a low manufacturing cost, and improves air conditioning with improved reliability. A machine is obtained.

［実施の形態２］
以上の実施の形態１では、上下２フロー時の風路構成を示しているが、次に、上吹出し単独の１フロー時の構成について説明する。
図２は本発明の実施の形態２に係る空気調和機の構成を説明する縦断面図である。なお、実施の形態１（図１）と同一又は相当する部分については同一の符号を付し、一部の説明を省略する。 [Embodiment 2]
In the first embodiment described above, the air path configuration at the time of the upper and lower two flows is shown. Next, the configuration at the time of one flow of the upper blowing alone will be described.
FIG. 2 is a longitudinal sectional view illustrating the configuration of an air conditioner according to Embodiment 2 of the present invention. In addition, the same code | symbol is attached | subjected about the part which is the same as that of Embodiment 1 (FIG. 1), or equivalent description.

図２において、下方風向可変板６は回転することで下方吹出口４を密閉している。また、破線Ａは熱交換器１３の下端縁１３ａと上方リアガイダ１４の下端縁１４ａとを結んだ線であり、セパレータ１２のコブ１２ｃの頂点は、破線Ａよりも背面側に位置することを特徴としている。すなわち、以上のようにセパレータ１２を構成しているので、上吹き１フロー時においても熱交換器１３の下方から吸い込んだ空気はコブ１２ｃが抵抗とならずなめらかにセパレータ１２に沿って流れるため、風量低下が起こらず、且つ低騒音化が可能となる。   In FIG. 2, the lower air direction variable plate 6 seals the lower outlet 4 by rotating. The broken line A is a line connecting the lower end edge 13a of the heat exchanger 13 and the lower end edge 14a of the upper rear guider 14, and the apex of the bump 12c of the separator 12 is located on the back side of the broken line A. It is said. That is, since the separator 12 is configured as described above, the air sucked from the lower side of the heat exchanger 13 flows smoothly along the separator 12 without the resistance of the bump 12c even at the time of one flow of top blowing. The air volume does not decrease and the noise can be reduced.

［実施の形態３］
図３は本発明の実施の形態３に係る空気調和機のセパレータの要部縦断面図である。なお、実施の形態１（図１）と同一又は相当する部分については同一の符号を付し、一部の説明を省略する。
図３において、断面略円弧状のコブ１２ｃの頂点は、上方貫流ファン９の中心からの距離ｈ１と下方貫流ファン１０の中心からの距離ｈ２が等しくなる位置（ｈ１＝ｈ２）に配置されている。
また、コブ１２ｃに連なる上方谷部１２ｂおよび下方谷部１２ｄのカーブは、点線Ｂのように深過ぎても、また点線Ｃのように浅過ぎても吸い込んだ風が極端に曲げられて抵抗になるため好ましくなく、なめらかに導かれるカーブを形成することが重要である。またカーブは使用するファンや熱交換器の仕様によっても変動する。 [Embodiment 3]
FIG. 3 is a longitudinal sectional view of a main part of a separator of an air conditioner according to Embodiment 3 of the present invention. In addition, the same code | symbol is attached | subjected about the part which is the same as that of Embodiment 1 (FIG. 1), or equivalent description.
In FIG. 3, the apex of the bump 12c having a substantially arc-shaped cross section is disposed at a position (h1 = h2) where the distance h1 from the center of the upper cross-flow fan 9 and the distance h2 from the center of the lower cross-flow fan 10 are equal. .
Also, the curves of the upper valley 12b and the lower valley 12d connected to the bump 12c are too deep as shown by the dotted line B and too shallow as shown by the dotted line C. Therefore, it is not preferable and it is important to form a smoothly guided curve. The curve also varies depending on the specifications of the fan and heat exchanger used.

以上のように、上方ファン９および下方ファン１０のほぼ中間位置に断面略円弧状状のコブ１２ｃを配置することで、上下の風量比が略等しくなり（１：１に近づき）、熱交換器１３を通過する空気の速度が均一化されることで低騒音化になる。さらに、熱交換器１３を通過する空気の速度が均一化されることで、熱交換の偏りがなくなり熱交換効率が向上する。   As described above, the upper and lower airflow ratios are substantially equal (approaching 1: 1) by disposing the bump 12c having a substantially arc-shaped cross section at a substantially intermediate position between the upper fan 9 and the lower fan 10, and the heat exchanger Since the speed of the air passing through 13 is made uniform, noise is reduced. Furthermore, since the speed of the air passing through the heat exchanger 13 is equalized, there is no bias in heat exchange, and heat exchange efficiency is improved.
