Description

【0001】
【発明の属する技術分野】
この発明は空気調和機に関し、詳しくは空気調和機における熱交換器の構造に関するものである。
【0002】
【従来の技術】
従来の空気調和機(例えば実開昭64−53818号公報)について、図2に基づいて説明する。図2は空気調和機の室内ユニットにおける縦断面図である。図において、51は箱形のケーシングであり、このケーシング51の上面に吸込口52を、前面下部に吹出口53をそれぞれ形成すると共に、ケーシング51の内部下方にはクロスフローファン54を設け、上記吸込口52とクロスフローファン54との間に、並列配置した多数の冷却フィン55a、55a・・に伝熱管55bを往復して貫通させてなる熱交換器55を配置している。そしてクロスフローファン54により吸込口52から吸い込んだ空気を、熱交換器55で熱交換し、吹出口53から吹き出すようにしている。さらにこの空気調和機では、熱交換器55を後方へ傾斜させることにより、ケーシング51の高さを抑えてコンパクト化を図っている。
【0003】
【発明が解決しようとする課題】
このように熱交換器55を傾斜させると、熱交換器55の水平投影面積が増すから、ケーシングの奥行き寸法が増すことになり、ケーシングの薄形化を進めることができない。また熱交換器55の表面に生じた結露は、本来下側に配置されたドレンパン56に全て回収されるのであるが、熱交換器55が傾斜しているため、ドレン水は熱交換器55の背面側に集まり、このドレン水が背面を伝ってクロスフローファン54の付近まで下降してきたときに、熱交換器55を通過する空気流により飛散し、これが吹出口53から霧状になって吹き出されるという問題がある。この問題を解決するために、図2の空気調和機では、熱交換器55の前面下部を閉塞して空気流の流入を阻止するようにしているが、これでは別途に閉塞部材57が必要となり、製造コストの上昇を招く。
【0004】
この発明は上記従来の欠点を解決するためになされたものであって、その目的は、基本的には熱交換器の傾斜配置という構成を採用してケーシング高さを抑えながら、ケーシングの奥行き寸法を短くしてケーシングの薄形化を図ると共に、熱交換器に閉塞部材を設けることなくドレン水の吹き出しを防止できる空気調和機を提供することにある。
【0005】
【課題を解決するための手段】
そこで請求項1の空気調和機は、ケーシングの前面又は上面の吸込口とケーシングの内部に設けたクロスフローファンとの間に熱交換器を配置した空気調和機において、熱交換器5を、ケーシング前面1aとクロスフローファン4との間でドレンパン6上にほぼ直立する第1熱交換器7と、この第1熱交換器7の上側に連設され、且つ後方へ傾斜した第2熱交換器8とにより構成し、第1熱交換器7よりも第2熱交換器8の前後厚さを厚く形成して成り、さらに第2熱交換器8の下端前部8cが、ほぼ第1熱交換器7の前面7cに揃うように斜めにカットされていることを特徴としている。
【0006】
この空気調和機では、第2熱交換器8の傾斜配置によりケーシング高さが抑えられる。ケーシング1の奥行き寸法を支配するクロスフローファン前後の空間ではクロスフローファン4の前側に第1熱交換器7が配置されるが、この第1熱交換器7は直立しており、且つ第2熱交換器8よりも薄く形成されているから、それだけケーシング1の奥行き寸法は短くなる。また第1熱交換器7は直立するから、ドレン水がクロスフローファン4の付近で冷却フィンのほぼ全面を伝って均一に降下することになり、空気流に飛散されることなくドレンパン6に集められる。また、この空気調和機では、例えば両熱交換器7、8を連設部において背面が一致するように配置したときには、第2熱交換器8の下端前部8cがほぼ第1熱交換器7の前面7cに揃えられるので、さらにケーシング1の奥行き寸法は短くなる。
【0007】
また請求項2の空気調和機は、請求項1の空気調和機において、伝熱管7b、8bが、第1熱交換器7では1列に、第2熱交換器8では前後2列に配列されていることを特徴としている。
【0008】
この空気調和機では、配列数の差に応じて第1熱交換器7よりも第2熱交換器8の方が厚くなる。また単位面積あたりの熱交換容量は第1熱交換器7よりも第2熱交換器8の方が大きくなるが、クロスフローファン4との距離は第1熱交換器7よりも第2熱交換器8の方が離れるので、各熱交換器7、8による熱交換が均一に行われる。
【0011】
【発明の実施の形態】
次にこの発明の空気調和機の具体的な実施形態について、図面を参照しつつ詳細に説明する。図1はこの発明の一実施形態であって、空気調和機の室内ユニットにおける縦断面図である。
【0012】
図において、1は箱形のケーシングであり、このケーシング1の前面1aにおける上部に吸込口2を、下部に吹出口3をそれぞれ形成すると共に、ケーシング1の内部下方にはクロスフローファン4を設け、上記吸込口2とクロスフローファン4との間に熱交換器5を配置している。そしてクロスフローファン4により吸込口2から吸い込んだ空気を、熱交換器5で熱交換し、吹出口3から吹き出すようにしている。
【0013】
上記熱交換器5は、ケーシング前面1aとクロスフローファン4との間においてドレンパン6上に直立する第1熱交換器7と、この第1熱交換器7の上側に連設され、且つ後方へ傾斜した第2熱交換器8とにより構成されている。第1熱交換器7は、横方向(図の紙面に垂直な方向)に並列配置した多数の冷却フィン7a、7a・・に伝熱管7bを往復、貫通させてなり、この第1熱交換器7を図のように縦に断面して側方からみると、伝熱管7bが1列だけ配列されている。一方、第2熱交換器8は、横方向に並列配置した多数の冷却フィン8a、8a・・に伝熱管8b、8bを往復、貫通させてなり、この第2熱交換器8を図のように縦に断面して側方からみると、伝熱管8bが前後2列に配列されている。したがって第1熱交換器7よりも第2熱交換器8の方が前後厚さが厚く形成されている。また両熱交換器7、8は、連設部において背面が一致するように配置されているが、第2熱交換器8の下端前部8cが、ほぼ第1熱交換器7の前面7cに揃うように斜めにカットされている。なお9はクロスフローファン4用の舌部である。
【0014】
上記構成の空気調和機では、第2熱交換器8の傾斜配置によりケーシング高さが抑えられる。またケーシング1の奥行き寸法を支配するクロスフローファン前後の空間ではクロスフローファン4の前側に第1熱交換器7が配置されるが、この第1熱交換器7は直立しており、且つ第2熱交換器8よりも薄く形成されているから、それだけケーシング1の奥行き寸法は短くなり、薄形化できる。さらに第2熱交換器8のドレン水は冷却フィン8aを伝って第1熱交換器7へと降下するから、これら両熱交換7、8のドレン水はクロスフローファン4の付近では第1熱交換器7の冷却フィン7aを伝って降下していく。その場合、第1熱交換器7は直立しているから、ドレン水が第1熱交換器7の冷却フィン7aのほぼ全面を伝って均一に降下することになり、空気流に飛散されることなくドレンパン6に集められる。したがって従来例のように熱交換器7に閉塞部材を設けることなくドレン水の吹き出しを防止することができ、製造コストを低減することができる。
【0015】
また単位面積あたりの熱交換容量は第1熱交換器7よりも第2熱交換器8の方が大きくなるが、クロスフローファン4との距離は第1熱交換器7よりも第2熱交換器8の方が離れるので、各熱交換器7、8による熱交換が均一に行われ、温度差のある空気の混流による結露等を防止できる。
【0016】
さらに第2熱交換器8の下端前部8cが、ほぼ第1熱交換器7の前面に揃うので、ケーシング1の奥行き寸法は更に短くなり、ケーシング1を一層薄形化することができる。
【0017】
なお、上記実施形態ではケーシング1の前面1aに吸込口2を形成したが、吸込口をケーシングの上面に形成したもの、前面及び上面の両方に形成したものについても本発明を適用することができる。また上記実施形態ではケーシング1の前面1aに吹出口3を形成したが、吹出口をケーシングの底面に形成したもの、前面及び底面の両方に形成したものについても本発明を適用することができる。
【0018】
【発明の効果】
以上のように請求項1の空気調和機では、第2熱交換器の傾斜配置によりケーシング高さを抑え、第1熱交換器の直立配置及び薄形化によりケーシングの奥行き寸法を短くしたので、ケーシングを低くしながら薄形化できる。またドレン水がクロスフローファンの付近で第1熱交換器の冷却フィンのほぼ全面を伝って均一に降下するから、熱交換器に閉塞部材を設けることなくドレン水の吹き出しを防止することができ、製造コストを低減することができる。また、第2熱交換器の下端前部が、ほぼ第1熱交換器の前面に揃うように斜めにカットされているので、さらにケーシングの奥行き寸法が短くなり、ケーシングを薄形化できる。
【0019】
また請求項2のようにすれば、第1熱交換器及び第2熱交換器による熱交換が均一に行われ、温度差のある空気の混流による結露等を防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner, and more particularly to a structure of a heat exchanger in the air conditioner.
[0002]
[Prior art]
A conventional air conditioner (for example, Japanese Utility Model Laid-Open No. 64-53818) will be described with reference to FIG. FIG. 2 is a longitudinal sectional view of the indoor unit of the air conditioner. In the figure, reference numeral 51 denotes a box-shaped casing. A suction port 52 is formed on the upper surface of the casing 51, and a blow-out port 53 is formed on the lower part of the front surface. A cross-flow fan 54 is provided below the casing 51. Between the suction port 52 and the cross flow fan 54, a heat exchanger 55 is disposed in which a large number of cooling fins 55a, 55a,. The air sucked from the suction port 52 by the cross flow fan 54 is heat-exchanged by the heat exchanger 55 and blown out from the air outlet 53. Furthermore, in this air conditioner, the height of the casing 51 is suppressed and the size is reduced by inclining the heat exchanger 55 backward.
[0003]
[Problems to be solved by the invention]
When the heat exchanger 55 is tilted in this way, the horizontal projection area of the heat exchanger 55 is increased, so that the depth dimension of the casing is increased, and the casing cannot be thinned. In addition, all the dew condensation generated on the surface of the heat exchanger 55 is collected in the drain pan 56 originally disposed on the lower side. However, since the heat exchanger 55 is inclined, the drain water is supplied to the heat exchanger 55. When this drain water gathers on the back side and descends to the vicinity of the cross flow fan 54 through the back side, it is scattered by the air flow passing through the heat exchanger 55, and this is sprayed out from the air outlet 53 in the form of a mist. There is a problem of being. In order to solve this problem, in the air conditioner of FIG. 2, the lower part of the front surface of the heat exchanger 55 is blocked to prevent the inflow of airflow, but this requires an additional blocking member 57. Incurs an increase in manufacturing costs.
[0004]
The present invention has been made in order to solve the above-described conventional drawbacks, and its purpose is basically to adopt a configuration in which the heat exchanger is inclined to suppress the casing height while reducing the casing height. It is intended to provide an air conditioner that can reduce the thickness of the casing by reducing the length of the casing and can prevent the drain water from blowing out without providing a blocking member in the heat exchanger.
[0005]
[Means for Solving the Problems]
Therefore, the air conditioner according to claim 1 is an air conditioner in which a heat exchanger is disposed between a suction port on the front surface or upper surface of the casing and a cross flow fan provided in the casing. A first heat exchanger 7 that is substantially upright on the drain pan 6 between the front face 1a and the crossflow fan 4, and a second heat exchanger that is connected to the upper side of the first heat exchanger 7 and is inclined rearward. 8, the front and rear thicknesses of the second heat exchanger 8 are formed thicker than the first heat exchanger 7 , and the lower front part 8 c of the second heat exchanger 8 is substantially the first heat exchange. It is characterized by being obliquely cut so as to align with the front surface 7c of the vessel 7 .
[0006]
In this air conditioner, the casing height is suppressed by the inclined arrangement of the second heat exchanger 8. In the space before and after the cross flow fan that governs the depth dimension of the casing 1, the first heat exchanger 7 is disposed on the front side of the cross flow fan 4, and the first heat exchanger 7 is upright and second. Since it is formed thinner than the heat exchanger 8, the depth dimension of the casing 1 is shortened accordingly. Further, since the first heat exchanger 7 stands upright, the drain water is uniformly lowered along the entire surface of the cooling fin in the vicinity of the cross flow fan 4 and collected in the drain pan 6 without being scattered by the air flow. It is done. Further, in this air conditioner, for example, when the two heat exchangers 7 and 8 are arranged so that the backs thereof coincide with each other in the connecting portion, the lower end front portion 8c of the second heat exchanger 8 is substantially the first heat exchanger 7. Therefore, the depth dimension of the casing 1 is further shortened.
[0007]
The air conditioner according to claim 2 is the air conditioner according to claim 1, wherein the heat transfer tubes 7 b and 8 b are arranged in one row in the first heat exchanger 7 and in two rows in the front and rear in the second heat exchanger 8. It is characterized by having.
[0008]
In this air conditioner, the second heat exchanger 8 is thicker than the first heat exchanger 7 according to the difference in the number of arrangements. Further, the heat exchange capacity per unit area is larger in the second heat exchanger 8 than in the first heat exchanger 7, but the distance from the cross flow fan 4 is the second heat exchange than in the first heat exchanger 7. Since the unit 8 is separated, heat exchange by the heat exchangers 7 and 8 is performed uniformly.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, specific embodiments of the air conditioner of the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal sectional view of an indoor unit of an air conditioner according to an embodiment of the present invention.
[0012]
In the figure, reference numeral 1 denotes a box-shaped casing. A suction port 2 is formed at the upper part and a blower port 3 is formed at the lower part of the front surface 1a of the casing 1, and a cross flow fan 4 is provided below the inside of the casing 1. A heat exchanger 5 is disposed between the suction port 2 and the cross flow fan 4. The air sucked from the suction port 2 by the cross flow fan 4 is heat-exchanged by the heat exchanger 5 and blown out from the blowout port 3.
[0013]
The heat exchanger 5 is connected to the first heat exchanger 7 standing upright on the drain pan 6 between the casing front face 1a and the cross flow fan 4, and connected to the upper side of the first heat exchanger 7 and to the rear. The second heat exchanger 8 is inclined. The first heat exchanger 7 is formed by reciprocating and penetrating a heat transfer tube 7b through a large number of cooling fins 7a, 7a,... Arranged in parallel in the lateral direction (direction perpendicular to the drawing sheet). When the section 7 is vertically sectioned and viewed from the side as shown in the figure, one row of heat transfer tubes 7b are arranged. On the other hand, the second heat exchanger 8 is formed by reciprocating and penetrating the heat transfer tubes 8b, 8b through a large number of cooling fins 8a, 8a,. The heat transfer tubes 8b are arranged in two rows in the front-rear direction as viewed from the side in a longitudinal section. Therefore, the thickness of the second heat exchanger 8 is larger than that of the first heat exchanger 7. Moreover, although both the heat exchangers 7 and 8 are arrange | positioned so that a back surface may correspond in a connection part, the lower end front part 8c of the 2nd heat exchanger 8 is substantially on the front surface 7c of the 1st heat exchanger 7. It is cut diagonally so as to align. Reference numeral 9 denotes a tongue for the cross flow fan 4.
[0014]
In the air conditioner having the above configuration, the casing height is suppressed by the inclined arrangement of the second heat exchanger 8. In the space before and after the cross flow fan that governs the depth dimension of the casing 1, the first heat exchanger 7 is disposed on the front side of the cross flow fan 4. The first heat exchanger 7 is upright and Since it is formed thinner than the two heat exchangers 8, the depth dimension of the casing 1 is shortened accordingly and can be thinned. Further, since the drain water of the second heat exchanger 8 travels down the cooling fins 8 a to the first heat exchanger 7, the drain water of both the heat exchanges 7 and 8 is the first heat in the vicinity of the cross flow fan 4. It descends along the cooling fins 7a of the exchanger 7. In that case, since the 1st heat exchanger 7 is standing upright, drain water will descend | fall uniformly through the whole surface of the cooling fin 7a of the 1st heat exchanger 7, and will be scattered by an air flow. It is collected in the drain pan 6 without. Accordingly, the drainage of the drain water can be prevented without providing a closing member in the heat exchanger 7 as in the conventional example, and the manufacturing cost can be reduced.
[0015]
Further, the heat exchange capacity per unit area is larger in the second heat exchanger 8 than in the first heat exchanger 7, but the distance from the cross flow fan 4 is the second heat exchange than in the first heat exchanger 7. Since the unit 8 is separated, heat exchange by the heat exchangers 7 and 8 is performed uniformly, and condensation due to a mixed flow of air having a temperature difference can be prevented.
[0016]
Furthermore, since the lower end front portion 8c of the second heat exchanger 8 is substantially aligned with the front surface of the first heat exchanger 7, the depth dimension of the casing 1 is further shortened, and the casing 1 can be further thinned.
[0017]
In addition, in the said embodiment, although the suction inlet 2 was formed in the front surface 1a of the casing 1, this invention is applicable also to what formed the suction inlet in both the front surface and the upper surface of the casing. . Moreover, in the said embodiment, although the blower outlet 3 was formed in the front surface 1a of the casing 1, this invention is applicable also to what formed the blower outlet in the bottom face of a casing, and both the front surface and the bottom face.
[0018]
【The invention's effect】
As described above, in the air conditioner of claim 1, the casing height is suppressed by the inclined arrangement of the second heat exchanger, and the depth dimension of the casing is shortened by the upright arrangement and thinning of the first heat exchanger. The casing can be made thin while being lowered. In addition, since the drain water descends uniformly over almost the entire surface of the cooling fin of the first heat exchanger near the cross flow fan, it is possible to prevent the drain water from being blown out without providing a blocking member in the heat exchanger. Manufacturing cost can be reduced. Moreover, since the lower end front part of the 2nd heat exchanger is cut diagonally so that it may align with the front surface of a 1st heat exchanger substantially, the depth dimension of a casing becomes still shorter and a casing can be reduced in thickness.
[0019]
According to the second aspect of the present invention, heat exchange by the first heat exchanger and the second heat exchanger is performed uniformly, and condensation due to a mixed flow of air having a temperature difference can be prevented.
