Description

【０００１】
【発明の属する技術分野】
本願発明は、分離型空気調和機の室内ユニットに特徴を有するものであり、より詳しくは熱交換器の配置構成に関するものである。
【０００２】
【従来の技術】
床置き型室内ユニットを有する分離型空気調和機の従来の技術について図５を用いて説明する。図５は分離型空気調和機の箱型の室内ユニットの内部構成を示す構成模式図である。まず同図（ａ）に示す様に従来の空気調和機は、筐体下方に吸い込み部４及び送風部３を有し、その上方に熱交換器２及び吹き出し部６を配置して、吸い込み部４、送風部３、熱交換器２、吹き出し部６の順に空気が流れる送風回路が構成されている。
【０００３】
吸い込み部４は前面枠にスリットが形成されて筐体周囲から空気を吸い込むように構成されており、集塵のためのフィルタ（図示せず）がその送風下流側に配置されている。送風部３はシロッコファンなどのファン３ａとケーシング３ｂを用いて構成されており、吸い込み部４からの空気を吸い込んで上方に配置されている熱交換器２方向に吹き出す。熱交換器２は前面下方から背面上方にかけて略平面的に配置されている。また、吹き出し部６は吹き出し面が略長方形の吹き出し枠６ｃと、上下方向の風向変更を行う上下羽根６ａと、左右方向の風向変更を行う左右羽根６ｂとを有して構成されている。なお、同図に矢印で示したように送風部３から吹き出される送風は一般的に背面側の風速分布が高く、補助加熱部となるヒータ７は熱交換器上方の前面側に配置されている。
【０００４】
一般にこの種の室内ユニットは背の高い構成になっているが、暖房時の暖気を床面に到達させる必要もあるため、極力高さを低くするニーズもある。一方では省エネルギー化のため室内熱交換器をできるだけその伝熱面積がおおきくなるように構成するニーズもあり、そのために熱交換器を大きくしようとすると熱交換器の列方向に長さをとる必要があるため室内ユニットの高さが高くなってしまう。このとき、熱交換器の列数を増大させて熱交換面積を拡大する方法もあるが、送風抵抗、騒音、成形などの面で課題があり、実現は困難である。現在商品化されているこの種の室内ユニットに配置された熱交換器は通常１列か２列で構成されており、多くても３列程度である。
【０００５】
上記のような相反するニーズを解決する方法としては、特許文献１に示されるように、熱交換器を室内ユニット筐体内で側方から見て略「人」の字になるように折り曲げて配置構成する考案が開示されている。この構成について概要を図５（ｂ）に示している。熱交換器２は上下方向に略逆Ｖ字となるように前面側熱交換器２ａと背面側熱交換器２ｂとを折り曲げた形で配置して構成しており、前面側熱交換器２ａと背面側熱交換器２ｂそれぞれの下端部には運転中に発生する凝縮水を受けるように水受け部５がそれぞれ配置されている。このように構成することで、同じ熱交換器面積でも室内ユニットの高さを低く構成することができる。
【０００６】
【特許文献１】
中国実用新案ＣＮ２４４６４４２Ｙ号公報
【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に記載の空気調和機の室内ユニットでの熱交換器構成では、次のような課題がある。まず第一に水受け部５は熱交換器の下端において前面側及び背面側の少なくとも２箇所配置する必要があり部品点数が多くなる。更にはこの水受け部５を前面・背面両方配置するため、下方の送風部から送られる送風の通路断面積が狭くなり、送風性能が若干低下してしまう可能性がある。
【０００８】
第二に前面側熱交換器２ａと背面側熱交換器２ｂとが重なる最上端の屈曲部には、前面側熱交換器２ａと背面側熱交換器２ｂとを連結するとともに、この屈曲部の上面側にはシールテープ２ｃを貼り付けるなどして熱交換器の重なりが小さく送風抵抗が小さいとともに、十分に熱交換されずに吹き出される可能性のある空気流れに対する処理が必要となり、コストアップになりうる。
【０００９】
そして第三には、この種の空気調和機は能力に応じて補助加熱の手段としてヒータ７を追加構成していることがあるが、上記構成の室内ユニットでは熱交換器の面に張り付けるように配置すれば、前面側または背面側の何れか一方の熱交換器のみを通過した空気が加熱されるようになり、吹き出しでの温度むらが懸念される。仮に送風の主流が流れる背面側熱交換器２ｂの方に補助ヒータ７を配置したとすれば、補助ヒータ７のメンテナンス時には背面側に手が届くように筐体を分解する必要があり、修理が困難である。
【００１０】
本願発明は、上記課題に鑑み、より簡易な構成で従来と同等以上の性能・効率を発揮するとともに、室内ユニットの高さをより低く構成できるコンパクトな分離型空気調和機を提供するものである。
【００１１】
【課題を解決するための手段】
上記課題を解決するために、本願発明の分離型空気調和機は、筐体下方に吸い込み部及び送風部を、上方に熱交換器及び吹き出し部を配置した分離型空気調和機の室内ユニットにおいて、熱交換器は上方に開放となるように屈曲して構成されており、水受け部は熱交換器の最下部の屈曲部に対向して配置されていることを特徴とするものである。
【００１２】
【発明の実施の形態】
本願請求項１の発明に係る分離型空気調和機は、室内ユニットが筐体下方に吸い込み部及び送風部を、上方に熱交換器及び吹き出し部を配置しており、室内ユニットに具備される熱交換器は上方に開放となるように屈曲して構成されており、水受け部はこの熱交換器の最下部の屈曲部に対向して配置されていることを特徴とするものである。すなわち、上下方向に略Ｖ字、Ｕ字の形状に構成されているのである。屈曲部はＶ字形上の場合一箇所であるが、数ヶ所設けて多段折り曲げにしてもよい。または熱交換器を側面方向の形状で略円弧形などのように曲面的に構成してもよい。要するに最下部の折り曲げ部で１列の水受け部にて凝縮水を受けるように構成できればよい。
【００１３】
なお、折り曲げ部とは、熱交換器を形成するフィンが連続していても不連続でもよく、要するに熱交換器として連続して構成されていることをいう。
【００１４】
この構成により、従来と同等以上の熱交換器を同じかより低い高さの室内ユニット筐体内に配置して性能の高い室内ユニットを構成することができるとともに、水受け部は１ヶ所で済み送風の抵抗がより小さく、しかも部品点数の少ない室内ユニットを提供すろことができる。更には熱交換器の最下方の屈曲部にはこの部位に対向するように水受け部を設けているので、上述のようにシ−ル材等を貼り付けて送風漏れしないように構成する必要がない。
【００１５】
また本願の請求項２の発明に係る分離型空気調和機は、水受け部の下方部は送風上流側に尖った形状を有することを特徴とし、これにより、下方からの空気流れに対して抵抗とならないようにするとともに、その形状によって水受け部で分岐されて熱交換器の前面側及び背面側に流れる空気流れの分流を制御することも可能となる。
【００１６】
また本願の請求項３の発明に係る分離型空気調和機は、補助加熱部を有し、この補助加熱部は熱交換器の上端開口部に配置されていることを特徴とするものであり、これによれば、熱交換器を通過した空気流れの大半がこの補助加熱部を通過するように構成できるとともに、室内ユニット筐体に対して熱交換器の上端を固定する部材を共用して、補助加熱部を固定することも可能であり、部品点数も少なく構成できる。
【００１７】
また本願の請求項４の発明に係る分離型空気調和機は、熱交換器上端部は、吹き出し部の吹き出し枠の下辺の水平面よりも下方になるように構成されていることを特徴とするものであり、室内ユニットの前方から熱交換器が見えず、美観が向上する。
【００１８】
また本願の請求項５の発明に係る分離型空気調和機は、補助加熱部は、吹き出し部の下辺の水平面よりも下方になるように構成されていることを特徴とするものであり、これによれば上記のように室内ユニットの前方から熱交換器が見えず、美観が向上するともに、吹き出し部から手を挿入して補助加熱部に触れてしまう危険性を回避するための措置も不要となる。
【００１９】
そして、本願の請求項６の発明に係る分離型空気調和機は、水受け部に対向する位置より背面側の熱交換器の少なくとも一部は、水受け部に対向する位置より前面側の熱交換器よりも列数が多いことを特徴とするものであり、背面側熱交換器側の風速分布が前面側に比べて通常高いことを利用して、背面側の送風抵抗を増して、風速分布を前面側と背面側とでより均一化させるとともに、熱交換器の伝熱面積を増やして性能を向上させることができる。
【００２０】
以下、図面を用いて、本願発明の実施の形態について説明する。なお、従来の技術で示した図５と同一の構成要素には同一の図番を付してその詳細な説明は割愛する。
【００２１】
（実施の形態）
まず本願発明の実施の形態について図１、図２を用いて説明する。図１は本願発明の分離型空気調和機の室内ユニットの構成模式図であり、図２はその側面方向からの内部構成を示す模式図である。図１に示すように本願発明の分離型空気調和機の室内ユニット１は縦長箱型の筐体を有して構成されており、前面下方の吸い込み部４、送風機３、熱交換器２、吹き出し部６の順に流れる送風回路を内部に構成している。
【００２２】
特徴となるのは図２（ａ）に示されるように熱交換器がその上方側が開放となり略Ｖ字形状に構成されて下端に屈曲部２ｄを有して構成されており、この屈曲部２ｄと対向して水受け部５が配置されている。更に水受け部の送風上流側となる下面側には水受け部が送風の抵抗となるのを緩和し、また下方からの送風を前面側及び背面側に誘導分岐する凸形上部５ａを有している。図２（ｂ）に示すようにこの凸形状部５ａをその先端部が背面側に来るように構成すると、前面側熱交換器２ａへの風速分布が大きくなるように送風回路を構成できる。無論先端は図のように尖っていても、滑らかに構成されていてもよいが、少なくとも水受け部５の下面形状が送風の抵抗にならないように形成されているものである。
【００２３】
また、熱交換器２は最下端だけでなくその他の部位でも２ｃのように屈曲部を有して構成されていてもよいし、熱交換器の面は平面的でなく曲面的に構成されていてもよい。
【００２４】
そして、熱交換器２の上端部は吹き出し部６の吹き出し枠６ｃの下辺部水平面よりも下方に配置するように構成されており、室内ユニット前面側から見て少なくとも熱交換器２が見えないようにすると、美観状好適である。
【００２５】
更には、補助加熱手段としてヒータ７を装備する場合にはヒータ７を熱交換器２ａ、２ｂの上端部に配置する。要するに、略Ｖ字型に構成された熱交換器２を通過した空気流れが吹き出し部６に導かれる際にその大半がこの部分を通過するのでむらが少なく効果的に空気流れを加熱することができ、吹き出し空気流の温度むらを小さくすることができる。
【００２６】
そしてより好適にはヒータが吹き出し部６の吹き出し枠６ｃの下辺部水平面よりも下方に配置する。そうすれば吹き出し部からユーザが手を挿入することがあっても、ユーザが触れにくくなり安全性が増す。更には、ヒータ７の固定のための部材（図示せず）を熱交換器２ａ、２ｂの上端部固定のための部材と共用させることで部品点数を少なくすることができ好適である。
【００２７】
また、熱交換器の配置構成は図３（ａ）に示すように前面側熱交換器２ａは上記と同様にして、背面側の熱交換器２ｂを室内ユニットの筐体上方まで伸ばして構成すれば、空気抵抗が少なくて熱交換面積を大きくすることができ、空気調和機自体の効率向上に好適である。この場合でも補助加熱のヒータ７は前面側熱交換器２ａと背面側熱交換器２ｂの上端部を渡すように配置されるとよい。
【００２８】
また、背面側熱交換器２ｂの風速分布の大きい場合など背面側熱交換器２ｂの列数を前面側熱交換器２ａの列数よりも大きく構成すると背面側熱交換器に送風抵抗になり前面・背面の風速分布がよりよい状態になる。無論、背面側熱交換器のフィンピッチを小さくしたり、フィンの切り起こし形状をより伝熱性能が向上するように構成することもできる。このようにしてコンパクトながら高性能の空気調和機室内ユニットを構成することができる。
【００２９】
【発明の効果】
以上の説明から明らかなように、本願発明によればより簡易な構成で従来と同等以上の性能・効率を発揮するとともに、室内ユニットの高さをより低く構成できるコンパクトな分離型空気調和機を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention has a feature in an indoor unit of a separation type air conditioner, and more particularly, relates to an arrangement of a heat exchanger.
[0002]
[Prior art]
A conventional technique of a separation type air conditioner having a floor-standing indoor unit will be described with reference to FIG. FIG. 5 is a schematic configuration diagram illustrating an internal configuration of a box-shaped indoor unit of the separation-type air conditioner. First, as shown in FIG. 1A, the conventional air conditioner has a suction unit 4 and a blowing unit 3 below a housing, and a heat exchanger 2 and a blowing unit 6 are disposed above the suction unit 4 and a blowing unit 3. A blower circuit through which air flows in the order of 4, blower unit 3, heat exchanger 2, and blowout unit 6 is configured.
[0003]
The suction part 4 has a slit formed in the front frame and is configured to suck air from around the housing, and a filter (not shown) for collecting dust is arranged on the downstream side of the blower. The blower unit 3 includes a fan 3a such as a sirocco fan and a casing 3b. The blower unit 3 sucks air from the suction unit 4 and blows the air toward the heat exchanger 2 disposed above. The heat exchanger 2 is arranged substantially planarly from the lower front side to the upper rear side. The blowing section 6 includes a blowing frame 6c having a substantially rectangular blowing surface, upper and lower blades 6a for changing the wind direction in the vertical direction, and left and right blades 6b for changing the wind direction in the horizontal direction. In addition, as shown by the arrow in the figure, the air blown from the air blowing unit 3 generally has a high wind speed distribution on the back side, and the heater 7 serving as the auxiliary heating unit is disposed on the front side above the heat exchanger. I have.
[0004]
Generally, this type of indoor unit has a tall configuration, but there is also a need to reduce the height as much as possible because warm air during heating needs to reach the floor surface. On the other hand, there is also a need to configure the indoor heat exchanger so that its heat transfer area is as large as possible to save energy.Thus, if the heat exchanger is to be made larger, it is necessary to take a length in the row direction of the heat exchanger. Therefore, the height of the indoor unit is increased. At this time, there is a method of increasing the number of rows of heat exchangers to increase the heat exchange area, but there are problems in terms of ventilation resistance, noise, molding, and the like, and it is difficult to realize the method. The heat exchangers arranged in this type of indoor unit currently commercialized are usually composed of one or two rows, and at most about three rows.
[0005]
As a method for solving the above contradictory needs, as shown in Patent Literature 1, a heat exchanger is bent and arranged in an indoor unit housing so as to have a substantially "person" shape when viewed from the side. The constituent devices are disclosed. An outline of this configuration is shown in FIG. The heat exchanger 2 is configured by arranging a front-side heat exchanger 2a and a rear-side heat exchanger 2b in a bent shape so as to form a substantially inverted V-shape in the vertical direction. Water receiving portions 5 are arranged at lower ends of the rear-side heat exchangers 2b, respectively, so as to receive condensed water generated during operation. With this configuration, the height of the indoor unit can be reduced even with the same heat exchanger area.
[0006]
[Patent Document 1]
Publication of Chinese Utility Model CN2446442Y
[Problems to be solved by the invention]
However, the configuration of the heat exchanger in the indoor unit of the air conditioner described in Patent Document 1 has the following problem. First, it is necessary to arrange the water receiving portion 5 at least at two locations on the front side and the rear side at the lower end of the heat exchanger, and the number of parts increases. Further, since the water receiving portion 5 is disposed on both the front surface and the rear surface, the passage cross-sectional area of the air blown from the lower air blowing portion is narrowed, and the air blowing performance may be slightly reduced.
[0008]
Second, the front-side heat exchanger 2a and the rear-side heat exchanger 2b are connected to the uppermost bent portion where the front-side heat exchanger 2a and the rear-side heat exchanger 2b overlap with each other. Attaching a sealing tape 2c to the upper surface side, etc., reduces the overlap of the heat exchangers and reduces the airflow resistance, and requires processing for airflow that may be blown out without sufficient heat exchange, increasing costs. Can be
[0009]
Thirdly, this type of air conditioner may additionally include a heater 7 as an auxiliary heating means depending on the capacity. In the indoor unit having the above configuration, the heater 7 may be attached to the surface of the heat exchanger. In this case, the air that has passed through only one of the heat exchangers on the front side and the back side is heated, and there is a concern about uneven temperature in the blowout. If the auxiliary heater 7 is arranged in the rear heat exchanger 2b through which the main flow of the air flows, it is necessary to disassemble the housing so that the rear side can be reached at the time of maintenance of the auxiliary heater 7. Have difficulty.
[0010]
The present invention has been made in view of the above problems, and provides a compact separation-type air conditioner that can exhibit the performance and efficiency equal to or higher than that of the related art with a simpler configuration and that can be configured to have a lower height of an indoor unit. .
[0011]
[Means for Solving the Problems]
In order to solve the above problem, the separation type air conditioner of the present invention is an indoor unit of a separation type air conditioner in which a suction unit and a blowing unit are arranged below a housing, and a heat exchanger and a blowing unit are arranged above. The heat exchanger is configured to be bent so as to be open upward, and the water receiving portion is arranged to face the lowermost bent portion of the heat exchanger.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
In the separation-type air conditioner according to the first aspect of the present invention, the indoor unit has a suction unit and a blower unit disposed below the housing, and a heat exchanger and a blowout unit disposed above the indoor unit. The exchanger is bent so as to be open upward, and the water receiving portion is arranged so as to face the lowermost bent portion of the heat exchanger. That is, they are formed in a substantially V-shaped or U-shaped shape in the vertical direction. The bent portion is one at the time of the V-shape, but it may be provided at a plurality of positions and bent in multiple steps. Alternatively, the heat exchanger may be formed in a curved shape such as a substantially circular arc shape in a lateral direction. In short, it is only necessary that the lowermost bent portion can be configured to receive the condensed water in the one row of water receiving portions.
[0013]
The bent portion means that the fins forming the heat exchanger may be continuous or discontinuous, that is, the fins are formed continuously as a heat exchanger.
[0014]
With this configuration, a high-performance indoor unit can be configured by arranging a heat exchanger equal to or higher than the conventional one in an indoor unit housing having the same or lower height, and the water receiving portion is provided in one place. An indoor unit having a smaller resistance and a smaller number of parts can be provided. Further, since a water receiving portion is provided at the lowermost bent portion of the heat exchanger so as to face this portion, it is necessary to attach a seal material or the like as described above to prevent air from leaking. There is no.
[0015]
Further, the separation type air conditioner according to the invention of claim 2 of the present application is characterized in that the lower portion of the water receiving portion has a shape that is pointed toward the upstream side of the air blower, and thereby, resistance to air flow from below is provided. In addition to the above, it is possible to control the branch of the air flow that is branched at the water receiving portion and flows to the front side and the rear side of the heat exchanger depending on the shape.
[0016]
Further, the separation type air conditioner according to the invention of claim 3 of the present application has an auxiliary heating unit, wherein the auxiliary heating unit is disposed at an upper end opening of the heat exchanger, According to this, while the majority of the airflow that has passed through the heat exchanger can be configured to pass through this auxiliary heating unit, the member that fixes the upper end of the heat exchanger to the indoor unit housing is shared, The auxiliary heating unit can be fixed, and the number of parts can be reduced.
[0017]
Further, the separation type air conditioner according to the invention of claim 4 of the present application is characterized in that the upper end of the heat exchanger is configured to be lower than the horizontal plane on the lower side of the blowing frame of the blowing section. Therefore, the heat exchanger cannot be seen from the front of the indoor unit, and the appearance is improved.
[0018]
Also, the separation type air conditioner according to the invention of claim 5 of the present application is characterized in that the auxiliary heating unit is configured to be lower than a horizontal plane on the lower side of the blowing unit, According to the above, the heat exchanger cannot be seen from the front of the indoor unit as described above, and the appearance is improved, and measures for avoiding the risk of inserting the hand from the blowing part and touching the auxiliary heating part are unnecessary. Become.
[0019]
Further, in the separation type air conditioner according to the invention of claim 6 of the present application, at least a part of the heat exchanger on the back side of the position facing the water receiving portion has the heat on the front side of the position facing the water receiving portion. The number of rows is larger than that of the heat exchanger, and the fact that the wind speed distribution on the rear heat exchanger side is usually higher than that on the front side increases The distribution can be made more uniform between the front side and the rear side, and the performance can be improved by increasing the heat transfer area of the heat exchanger.
[0020]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same components as those in FIG. 5 shown in the conventional art are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0021]
(Embodiment)
First, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a schematic diagram of a configuration of an indoor unit of a separation type air conditioner of the present invention, and FIG. 2 is a schematic diagram showing an internal configuration of the indoor unit from a side direction. As shown in FIG. 1, the indoor unit 1 of the separation type air conditioner of the present invention is configured to have a vertically long box-shaped casing, and a suction unit 4, a blower 3, a heat exchanger 2, and a blower at a lower front surface. A blower circuit that flows in the order of the part 6 is configured inside.
[0022]
As shown in FIG. 2 (a), the heat exchanger has a substantially V-shaped heat exchanger with an open upper side and a bent portion 2d at the lower end. The water receiving part 5 is arranged so as to face. Further, the lower surface side of the water receiving portion on the upstream side of the blower has a convex upper portion 5a for alleviating the water receiving portion from acting as a blower resistance and for guiding and branching the blower from below toward the front side and the rear side. ing. As shown in FIG. 2 (b), when the protruding portion 5a is configured such that the tip end thereof is on the back side, a blower circuit can be configured such that the wind speed distribution to the front side heat exchanger 2a is increased. Needless to say, the tip may be sharp as shown in the figure or may be smoothly formed, but is formed so that at least the lower surface shape of the water receiving portion 5 does not become a resistance to blowing.
[0023]
Further, the heat exchanger 2 may be configured to have a bent portion like 2c not only at the lowermost end but also at other portions, and the surface of the heat exchanger is configured not as a plane but as a curved surface. You may.
[0024]
And the upper end part of the heat exchanger 2 is comprised so that it may be arrange | positioned below the horizontal surface of the lower side of the blowing frame 6c of the blowing part 6, so that at least the heat exchanger 2 cannot be seen from the front side of an indoor unit. In this case, the appearance is favorable.
[0025]
Further, when the heater 7 is provided as the auxiliary heating means, the heater 7 is disposed at the upper end of the heat exchangers 2a and 2b. In short, most of the air flow that has passed through the heat exchanger 2 having a substantially V-shape is guided to the blowing section 6, so that the air flow can be effectively heated with less unevenness because most of the air flow passes through this portion. As a result, the temperature unevenness of the blown air flow can be reduced.
[0026]
More preferably, the heater is disposed below the horizontal surface of the lower side of the blowing frame 6c of the blowing section 6. By doing so, even if the user inserts his / her hand through the balloon, the user becomes less likely to touch and the safety is increased. Further, it is preferable that a member (not shown) for fixing the heater 7 is shared with a member for fixing the upper end portions of the heat exchangers 2a and 2b because the number of parts can be reduced.
[0027]
As shown in FIG. 3A, the arrangement of the heat exchanger is such that the front-side heat exchanger 2a is extended in the same manner as described above, and the rear-side heat exchanger 2b is extended to above the housing of the indoor unit. If this is the case, the air resistance can be reduced and the heat exchange area can be increased, which is suitable for improving the efficiency of the air conditioner itself. Also in this case, the heater 7 for auxiliary heating may be arranged so as to pass over the upper end portions of the front-side heat exchanger 2a and the rear-side heat exchanger 2b.
[0028]
Further, if the number of rows of the rear heat exchanger 2b is larger than the number of rows of the front heat exchanger 2a, for example, when the wind speed distribution of the rear heat exchanger 2b is large, the rear heat exchanger has a blowing resistance, so that the front heat exchanger has a blowing resistance. -The wind speed distribution on the back side is in a better state. Of course, the fin pitch of the back side heat exchanger may be reduced, or the cut-and-raised shape of the fin may be configured to further improve the heat transfer performance. In this way, a compact, high-performance air conditioner indoor unit can be configured.
[0029]
【The invention's effect】
As is clear from the above description, according to the present invention, a compact separation-type air conditioner that can exhibit the performance and efficiency equal to or higher than the conventional one with a simpler configuration and can be configured to have a lower indoor unit height is provided. Can be provided.
