Description

【0001】
【発明の属する技術分野】
この発明は、熱交換器で熱交換された空気を、吹出し口に設けられた風向板で風向調節を行って室内空間へと吹出して空調運転を行う空気調和装置に関する。
【0002】
【従来の技術】
これまでの空気調和装置では、吹出し口に風向板を備え、この風向板の方向を調節することにより、前記吹出し口から吹出される空気の風向調節を行い、被空調空間の空調運転を行っていた。この風向板は、ルーバーモータなどの駆動回路に接続されており、この駆動回路により、例えば、前記空気調和装置が冷房運転を行う場合には、前記風向板を略水平の方向へ向け、前記吹出し口から吹出される冷風を水平方向へと吹出させ、前記空気調和装置が暖房運転を行う場合には、前記風向板を下方へと向け、前記吹出し口から吹出される温風を下方方向へと吹出す様調整されていた。
【0003】
しかしながら、暖房運転時には、前記吹出し口から吹出される温風の温度が、被空調空間の空気の温度よりも高いため、前記吹出し口から吹出される空気に浮力が生じて前記吹出し口から吹出される空気の到達距離が短くなってしまうという問題があった。
【0004】
このため、吹出し口の下顎部に形状記憶合金を備えた突出体を設け、この突出体を吹出し口から吹出される前記冷風や前記温風の温度により前記形状記憶合金を伸縮させ、前記突出体を伸縮させて吹出し口の開口面積を制御することにより、前記吹出し口から吹出される空気の到達距離を制御することが提案されている(例えば、特許文献1参照)。
【0005】
また、上記ルーバーモータなどの駆動回路を収納するスペースを確保しなければならなため、風向板を方向を制御する駆動軸へ形状記憶合金による捩じりコイルバネを備え、前記捩じりコイルバネをヒータなどの加熱装置により加熱して前記吹出し口から吹出される空気の風向を制御することも提案されている(例えば、特許文献2参照)。

【特許文献2】
特開平11−237110号公報(第3図)
【0007】
【発明が解決しようとする課題】
しかしながら、上記特許文献1にあっては、前記吹出し口から吹出される温風の風速を上昇させて前記温風の到達距離を延ばすことはできるが、前記風向板を駆動させる駆動回路を備えなければならず、コストアップの要因となっていた。また、特許文献2にあっては、前記駆動回路を備えずとも前記風向板を駆動でき、前記吹出し口から吹出される温風の風向を制御することはできるが、暖房運転時、前記温風の到達距離を延ばすためには、前記温風の送風を行う送風機の回転数を上昇させるなどして風速を上昇させなければならなかった。このため、送風時の騒音が問題となっていた。
【0008】
本発明は、上記事情に鑑みてなされたものであり、送風機の回転数を上昇させることなく暖房運転時の温風の到達距離を延ばすと共に、ルーバーモータなどの駆動回路を用いずに風向調節を行う空気調和装置を提供することを目的とする。
【0009】
【課題を解決するための手段】
請求項1に記載の発明は、熱交換された空気を吹出す吹出し口へ、この吹出し口へ横方向へ延び、前記空気の風向を上下方向に調整する風向板を備えて空調運転を行う空気調和装置において、前記風向板の前記下側の面に接して風向補助板を設け、前記吹出し口から吹出される前記空気の温度に応じて、前記風向補助板の風上側を支点として前記風向補助板の風下側を前記風向板から離す手段を備え、前記吹出し口から吹出される前記空気の風向と、前記吹出し口から吹出される前記空気の風速とを調整することを特徴とするものである。
【0010】
請求項2に記載の発明は、請求項1に記載のものにおいて、前記風向補助板は、前記風向補助板の風上側の前記縁部に形状記憶合金など温度により変形する温度変形部材を備えたものであることを特徴とするものである。
【0011】
請求項3に記載の発明は、請求項1に記載のものにおいて、前記風向補助板は、形状記憶合金など温度により変形する温度変形部材であることを特徴とするものである。
【0012】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態について説明する。図1は、本発明の実施形態にかかる空気調和装置1の構成を示す図である。この図に示す様に、空気調和装置1は、室外ユニット2と室内ユニット3とがユニット間配管4で接続されて構成されており、室内ユニット2には、冷媒を圧縮する圧縮機10と、該圧縮機10から吐出された冷媒の循環方向を反転させる四方弁11と、前記冷媒と外気との熱交換を行わせる室外熱交換器12と、前記冷媒の減圧を行う減圧弁13と、該圧縮機10へ吸い込まれる冷媒の気液分離を行うアキュームレータ14と、室外熱交換器12へ外気を送風する室外送風機15が収納されている。
【0013】
室内ユニット3には、圧縮機10から吐出された冷媒を室内空気と熱交換させる室内熱交換器20と、室内減圧弁21と、室内熱交換器20への送風を行う室内送風機22とが収納されている。そして、この室内ユニット3は、例えば、図2に示す様に、室内ユニット本体23の下面に化粧パネル24が設けられており、前記化粧パネル24の中央には、室内の空気を吸い込む吸込みグリル25を備えた吸込み口26が設けられ、四辺の縁部には、この四辺の縁部に並行して延びる吹出し口28が設けられており、これら吹出し口28のそれぞれには、吹出し口28の延長方向へ延びる風向板27が備えられている。
【0014】
また、この室内ユニット3は、図3に示す様に、室内ユニット本体23内の天面中央には、室内送風機22を構成する室内送風モータ29が取り付けられ、この室内送風モータ29の回転軸へ室内送風ファン30が取り付けられている。また、室内送風機22の下方には、吸込み口26が設けられており、吸込みグリル25から吸込んだ室内空気をフィルタ32でろ過し、この吸込み口26から吸込むものとなっている。そして、この室内送風機22を囲う様に、室内熱交換器20が設けられており、室内ユニット本体23内で室内熱交換器20の外側には、吹出し経路31が設けられており、前記吸込み口26から吸込んだ前記室内空気を前記室内熱交換器20で熱交換させて冷却、或いは、加温した後、この吹出し経路31を流通させて吹出し口28から再度室内へと吹出している。また、室内熱交換器20の下方には、冷房運転時、この室内熱交換器20に結露し、滴下したドレン水を受けて図示しないドレンホースより室外へと排水するドレンパン33が備えられている。
【0015】
吹出し口28は、上記図2でも示した様に、化粧パネル24の四辺のそれぞれの縁部に並行に設けられており、吹出し口28には、それぞれ、これら吹出し口28から吹出される空気の風向を調整する風向板27が備えられている。
【0016】
風向板27は、図4に示す様に、化粧パネル24の前記縁部へ向けて若干湾曲した板で横方向へ延び、やや水平ぎみの角度で吹出し口28へと備えられており、この風向板27には、形状記憶合金やバイメタルなど、温度により変形する温度変形部材27aを介して、前記風向板27と略同等の長さの風向補助板27bが設けられている。この温度変形部材27aは、風向補助板27bの風上側の縁部に設けられ、一端を風向板27へ、他端を風向補助板27bへ固定されており、吹出し口28から吹出される前記空気の温度により、温度変形部材27aが変形し、風向補助板27bの風上側を支点として、この風向補助板27bの風下側が、前記風向板27へ引き寄せられたり、前記風向板27から離されたりするものとなっている。
【0017】
そして、温度変形部材27aおよび風向補助板27bの動作について説明すると、この風向補助板27bは、例えば、空気調和装置1が冷房運転を行った場合には、室内空気が室内熱交換器20で冷却され、冷風として吹出し口28から吹出されるため、この冷風の温度により、温度変形部材27aが変形し、風向補助板27bの風上側を支点として、風向補助板27bの風下側を実線矢印aに示す様に風向板27側へと引き寄せるものとなっている。これにより、空気調和装置1が冷房運転を行った時には、吹出し口28から吹出された冷風は、風向板27により略水平に吹出され、コアンダ効果により、室内ユニット3が据付けられた天井40の表面に沿って室内全体へと行き渡り易くなる。
【0018】
また、空気調和装置1が暖房運転を行った場合には、室内空気が室内熱交換器20で加温され、温風として吹出し口28から吹出されるため、この温風の温度により、温度変形部材27aが上記冷房運転時と逆方向に変形し、風向補助板27bの風上側を支点として、風向補助板27bの風下側は破線矢印bに示す様に風向板27から離されて下方へ向くこととなる。これにより、空気調和装置1が暖房運転を行った時には、吹出し口28吹出された温風は、風向補助板27bにより、上記冷房運転時よりも下方へ吹出されることとなる。さらに、前記風向補助板27bが、この風向補助板27bの風下側が風向板27から離され、吹出し口28が狭まることにより、前記温風の吹出される風速が上昇するため、前記温風の到達距離を延ばすことが可能となる。
【0019】
なお、この風向板27は、手動で吹出し口28から吹出される空気の吹出し方向を若干ではあるが、上下方向に変更することが可能となっている。それは、前記冷風や前記温風が直接使用者へ届いて不快感を招かない様にするためである。
【0020】
また、図5に示す様に、前記風向補助板27bの本体を形状記憶合金やバイメタルなど、温度により変形する温度変形部材で構成し、風向補助板34としても良い。
【0021】
この図5に示す風向補助板34も上記と同様、風向板27と略同等の長さの板状の部材とされ、風向板27の下側の面に接して設けられており、風向補助板34の風上側が風向板27へと取り付けられている。
【0022】
そして、吹出し口28から冷風が吹出される冷房運転では、前記風向補助板34は変形して実線矢印cに示す様に、風向補助板34の風上側を支点として、風向補助板34の風下側が風向板27へと引き寄せられて、上記同様、風向板27により略水平に吹出される。また、吹出し口28から温風が吹出される暖房運転では、風向補助板34は、上記と逆方向へ変形して破線矢印dに示す様に、風向補助板34の風上側を支点として、風向補助板34の風下側が風向板27から離れ、前記風向補助板34が下方へ向くため、吹出し口28から吹出される前記温風の風向も下方を向くと共に、吹出し口28が狭められ、前記温風の風速が上昇して、前記温風の到達距離を延ばすことが可能となる。
【0023】
なお、本実施の形態では、室内ユニット3を天井に埋め込まれて据付けられる四方向吹出しの天井カセット型として説明したが、これに限られるもので無いことは明らかで、上記天井に埋め込まれて据付けられる二方向吹出しの天井カセット型であっても、一方向吹出しの天井カセット型であっても、或いは、床面上に設置される床置き型であっても良い。つまり、吹出し口に風向を調整する風向板が備えられ、この風向板を上下方向に向けることにより、前記吹出し口から吹出される前記冷風や前記温風の風向を調整するものであれば良い。
【0024】
【発明の効果】
以上説明した様に、本発明によれば、風向板と同等の長さの風向補助板を前記風向板の下側の面に接して設け、前記吹出し口から吹出される空気の温度に応じて、前記風向補助板の風上側を支点として、前記風向補助板の風下側を前記風向板から離す手段を備えて、前記吹出し口から吹出される前記空気の風向と、前記吹出し口から吹出される前記空気の風速とを調整しているので、前記風向板の方向を変える駆動回路を用いずとも風向の変更が行えると共に、暖房運転時、前記吹出し口からから吹出される温風の到達距離を延ばすことができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which air exchanged by a heat exchanger is adjusted by a wind direction plate provided at an outlet, and is blown out into an indoor space to perform an air conditioning operation.
[0002]
[Prior art]
In the conventional air conditioners, the air outlet is provided with a wind direction plate, and by adjusting the direction of the wind direction plate, the air direction of the air blown out from the air outlet is adjusted, and the air conditioning operation of the air-conditioned space is performed. Was. The wind direction plate is connected to a drive circuit such as a louver motor. By this drive circuit, for example, when the air conditioner performs a cooling operation, the wind direction plate is directed in a substantially horizontal direction, When the cold air blown from the mouth is blown out in the horizontal direction, and the air conditioner performs the heating operation, the wind direction plate is directed downward, and the warm air blown out from the blowout opening is directed downward. It was adjusted to blow out.
[0003]
However, during the heating operation, the temperature of the warm air blown out from the outlet is higher than the temperature of the air in the air-conditioned space, so that the air blown out from the outlet has buoyancy and is blown out from the outlet. There is a problem that the reach distance of the air becomes short.
[0004]
For this purpose, a protrusion provided with a shape memory alloy is provided on the lower jaw of the outlet, and the shape memory alloy is expanded and contracted by the temperature of the cold air or the warm air blown from the outlet, and the protrusion is extended. It has been proposed to control the reach of air blown from the air outlet by controlling the opening area of the air outlet by expanding and contracting the air outlet (for example, see Patent Document 1).
[0005]
Further, since it is necessary to secure a space for accommodating a drive circuit such as the louver motor, a torsion coil spring made of a shape memory alloy is provided on a drive shaft for controlling the direction of the wind direction plate, and the torsion coil spring is heated by a heater. It has also been proposed to control the wind direction of air blown from the outlet by heating with a heating device such as the one described above (for example, see Patent Document 2).

[Problems to be solved by the invention]
However, in Patent Document 1, although the reach of the warm air can be extended by increasing the wind speed of the warm air blown from the outlet, a drive circuit for driving the wind direction plate must be provided. This had to be a factor in increasing costs. Further, in Patent Literature 2, the wind direction plate can be driven without the drive circuit, and the wind direction of the warm air blown out from the outlet can be controlled. In order to extend the reach of the air, the wind speed had to be increased by, for example, increasing the rotation speed of a blower for blowing the hot air. For this reason, the noise at the time of ventilation has been a problem.
[0008]
The present invention has been made in view of the above circumstances, extends the reach of warm air during heating operation without increasing the rotation speed of the blower, and adjusts the wind direction without using a drive circuit such as a louver motor. It is an object of the present invention to provide an air conditioner that performs the operation.
[0009]

Means for separating the leeward side of the plate from the wind direction plate, and adjusting a wind direction of the air blown out from the outlet and a wind speed of the air blown out from the outlet. .
[0010]
According to a second aspect of the present invention, in the first aspect, the wind direction auxiliary plate includes a temperature deformable member that deforms by a temperature such as a shape memory alloy at the edge on the windward side of the wind direction auxiliary plate. It is characterized by being.
[0011]
According to a third aspect of the present invention, in the first aspect, the wind direction auxiliary plate is a temperature deformable member such as a shape memory alloy that is deformed by temperature.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a diagram illustrating a configuration of an air conditioner 1 according to an embodiment of the present invention. As shown in this figure, the air conditioner 1 is configured by connecting an outdoor unit 2 and an indoor unit 3 with an inter-unit pipe 4, and the indoor unit 2 includes a compressor 10 for compressing a refrigerant, A four-way valve 11 for reversing the direction of circulation of the refrigerant discharged from the compressor 10, an outdoor heat exchanger 12 for performing heat exchange between the refrigerant and the outside air, a pressure reducing valve 13 for reducing the pressure of the refrigerant, An accumulator 14 for gas-liquid separation of the refrigerant sucked into the compressor 10 and an outdoor blower 15 for blowing outside air to the outdoor heat exchanger 12 are housed.
[0013]
The indoor unit 3 houses an indoor heat exchanger 20 for exchanging heat of the refrigerant discharged from the compressor 10 with indoor air, an indoor pressure reducing valve 21, and an indoor blower 22 for blowing air to the indoor heat exchanger 20. Have been. The indoor unit 3 has, for example, as shown in FIG. 2, a decorative panel 24 provided on the lower surface of the indoor unit main body 23, and a suction grill 25 for sucking indoor air is provided at the center of the decorative panel 24. Are provided at the four edges, and air outlets 28 extending in parallel with the four edges are provided. Each of these air outlets 28 is an extension of the air outlet 28. A wind direction plate 27 extending in the direction is provided.
[0014]
As shown in FIG. 3, the indoor unit 3 is provided with an indoor blower motor 29 constituting the indoor blower 22 at the center of the top surface in the indoor unit main body 23. An indoor blower fan 30 is attached. In addition, a suction port 26 is provided below the indoor blower 22, and the room air sucked from the suction grill 25 is filtered by a filter 32 and sucked from the suction port 26. An indoor heat exchanger 20 is provided so as to surround the indoor blower 22, and a blowout path 31 is provided outside the indoor heat exchanger 20 in the indoor unit main body 23, and the suction port is provided. After the room air sucked from 26 is exchanged with the indoor heat exchanger 20 for heat exchange or cooling or heating, the room air is circulated through the outlet path 31 and blown out again from the outlet 28 into the room. Below the indoor heat exchanger 20, there is provided a drain pan 33 that condenses on the indoor heat exchanger 20 during cooling operation, receives the dropped drain water, and drains it from the drain hose (not shown) to the outside of the room. .
[0015]
As shown in FIG. 2, the air outlets 28 are provided in parallel at the respective edges of the four sides of the decorative panel 24, and the air outlets 28 are respectively provided with the air blown out from these air outlets 28. A wind direction plate 27 for adjusting the wind direction is provided.
[0016]
As shown in FIG. 4, the wind direction plate 27 extends in the lateral direction with a plate slightly curved toward the edge of the decorative panel 24, and is provided to the outlet 28 at a slightly horizontal angle. The plate 27 is provided with a wind direction auxiliary plate 27b of substantially the same length as the wind direction plate 27 via a temperature deformable member 27a that is deformed by temperature, such as a shape memory alloy or a bimetal. The temperature deforming member 27a is provided on the windward edge of the wind direction auxiliary plate 27b, and has one end fixed to the wind direction plate 27 and the other end fixed to the wind direction auxiliary plate 27b. Temperature, the temperature deforming member 27a is deformed, and the leeward side of the wind direction auxiliary plate 27b is drawn to the wind direction plate 27 or separated from the wind direction plate 27 with the windward side of the wind direction auxiliary plate 27b as a fulcrum. It has become something.
[0017]
The operation of the temperature deforming member 27a and the wind direction auxiliary plate 27b will be described. For example, when the air conditioner 1 performs the cooling operation, the indoor air is cooled by the indoor heat exchanger 20. Then, since the cold air is blown out from the outlet 28, the temperature of the cold air deforms the temperature deforming member 27a, and the leeward side of the wind direction auxiliary plate 27b is indicated by a solid line arrow a with the windward side of the wind direction auxiliary plate 27b as a fulcrum. As shown in the drawing, it is drawn toward the wind direction plate 27 side. Thereby, when the air-conditioning apparatus 1 performs the cooling operation, the cool air blown out from the outlet 28 is blown substantially horizontally by the wind direction plate 27, and the surface of the ceiling 40 on which the indoor unit 3 is installed is formed by the Coanda effect. Along the entire room.
[0018]
When the air-conditioning apparatus 1 performs the heating operation, the indoor air is heated by the indoor heat exchanger 20 and is blown out from the outlet 28 as hot air. The member 27a is deformed in the opposite direction to that during the cooling operation, and the leeward side of the wind direction auxiliary plate 27b is separated from the wind direction plate 27 and directed downward with the leeward side of the wind direction auxiliary plate 27b as a fulcrum, as indicated by the dashed arrow b. It will be. Thus, when the air-conditioning apparatus 1 performs the heating operation, the warm air blown out of the outlet 28 is blown downward by the wind direction auxiliary plate 27b as compared with the cooling operation. Furthermore, the wind direction auxiliary plate 27b is separated from the wind direction plate 27 on the leeward side of the wind direction auxiliary plate 27b, and the outlet 28 is narrowed, so that the wind speed at which the hot air is blown out increases. It is possible to extend the distance.
[0019]
In addition, the direction of the air blown from the air outlet 28 of the wind direction plate 27 can be changed slightly in the vertical direction. This is to prevent the cold air or the warm air from reaching the user directly and not causing discomfort.
[0020]
Further, as shown in FIG. 5, the main body of the wind direction auxiliary plate 27b may be formed of a temperature deformable member such as a shape memory alloy or a bimetal which is deformed by temperature, and may be used as the wind direction auxiliary plate 34.
[0021]
Similarly to the above, the wind direction auxiliary plate 34 shown in FIG. 5 is also a plate-shaped member having a length substantially equal to that of the wind direction plate 27, and is provided in contact with the lower surface of the wind direction plate 27. The windward side of 34 is attached to the wind direction plate 27.
[0022]
In the cooling operation in which cool air is blown out from the outlet 28, the wind direction auxiliary plate 34 is deformed and the leeward side of the wind direction auxiliary plate 34 is set with the leeward side of the wind direction auxiliary plate 34 as a fulcrum as shown by a solid arrow c. It is drawn to the wind direction plate 27 and is blown out substantially horizontally by the wind direction plate 27 in the same manner as described above. Further, in the heating operation in which warm air is blown out from the outlet 28, the wind direction auxiliary plate 34 is deformed in the opposite direction to the above, and the wind direction of the wind direction auxiliary plate 34 is set as a fulcrum, as shown by a dashed arrow d. Since the leeward side of the auxiliary plate 34 is separated from the wind direction plate 27 and the wind direction auxiliary plate 34 is directed downward, the wind direction of the warm air blown from the outlet 28 is also directed downward, and the outlet 28 is narrowed. As the wind speed of the wind rises, it is possible to extend the reach of the warm air.
[0023]
In the present embodiment, the indoor unit 3 has been described as a four-way blowout ceiling cassette type which is embedded and installed on the ceiling. However, it is apparent that the present invention is not limited to this, and the indoor unit 3 is embedded and installed on the ceiling. It may be a two-way blowing ceiling cassette type, a one-way blowing ceiling cassette type, or a floor-standing type installed on a floor surface. That is, the air outlet may be provided with a wind direction plate for adjusting the wind direction, and the wind direction plate may be directed vertically to adjust the wind direction of the cold air or the hot air blown from the air outlet.
[0024]
【The invention's effect】
As described above, according to the present invention, a wind direction auxiliary plate having the same length as the wind direction plate is provided in contact with the lower surface of the wind direction plate, and according to the temperature of the air blown from the outlet.
