This relates to an integrated air conditioner that can be installed on a window, wall, etc.

吹出す。 That is, in the same figure, integrated air conditioner a
The main body is constituted by a substrate b, a partition e that separates an indoor ventilation system path c and an outdoor ventilation system path d on the substrate b, an outer box f, and the like. The outdoor ventilation system path d
Attach the outdoor heat exchanger h facing the back g,
Further, a motor i is attached to the partition wall e so that its rotation axis is perpendicular to the partition wall e. j
is a propeller fan attached to one end of this motor i and blows air toward the outdoor heat exchanger h, and is equipped with a ring p for scooping up water in the substrate b and blowing it toward the outdoor heat exchanger h. ing. K is a compressor that constitutes a well-known refrigeration cycle together with the outdoor heat exchanger h. Furthermore, indoor ventilation system path c
An indoor heat exchanger m is attached facing the front surface 1. o is a Sirotskov fan facing the indoor heat exchanger m, which is attached to the other end of the motor i, and blows the air passing through the indoor heat exchanger m to the wind barrel n.
ここで、この種の一体形空気調和機における理
想的な通風系路はいうまでもなく抵抗が小さいほ

る熱交換器の風の通過する面積（以後前面面積と
称す）が広くかつ風の通過する深さ（以後列数と
称す）が短かく、さらに通風系路が広くかつ曲り
が少なく滑らかであるなどの条件が必要となる。 Here, it goes without saying that the ideal ventilation path in this type of integrated air conditioner has a lower resistance, the better. The following conditions are required: the front surface area (hereinafter referred to as the front surface area) is large, the depth through which the air passes (hereinafter referred to as the number of rows) is short, and the ventilation path is wide and smooth with few bends.
このような条件が整つて始めて通風抵抗の小さ
い通風系路が構成され、低騒音で大風量の風を小
容量のモータを使用して通風できる一体形空気調
和機の実現が可能となる。 Only when these conditions are met will a ventilation system path with low ventilation resistance be constructed, making it possible to realize an integrated air conditioner that can blow a large volume of air with low noise using a small-capacity motor.
しかし従来のこの種の一体形空気調和機は壁を
貫通して取付けられたり、また窓に取付けられた

けずにすむようまた窓の採光などを著しく損わぬ
ようにするため極力小さく形成されていた。 However, conventional integrated air conditioners of this type are installed through walls or windows, so the front area is limited to avoid the need to make large holes in the wall and to accommodate window lighting. It was made as small as possible to avoid significant damage to the structure.
また従来この種の空気調和機は小形にすること

系路ｃ，ｄは狭く曲つた系路となつていた。特に
室内側通風系路は熱交換器を通過した後一旦狭め
られ、拡大した後曲げられるという複雑な系路と
なつていた。 Conventionally, this type of air conditioner was designed to reduce costs by making it smaller, so as shown in Fig. 1 and Fig. 2, one motor i can simultaneously operate the Shirodskov fan o on the indoor side and the propeller fan j on the outdoor side. Since the focus is on driving, it is necessary to place the indoor heat exchanger m and the outdoor heat exchanger h along the front 1 and back g of the integrated air conditioner a, respectively. Therefore, the indoor and outdoor ventilation system paths c and d that ventilate these heat exchangers m and h are narrow and curved paths. In particular, the ventilation system on the indoor side is a complicated system that is narrowed once it passes through the heat exchanger, then expanded and then bent.
その結果、通風のためにかなり大容量のモータ

い。 As a result, a fairly large-capacity motor i is required for ventilation, and the front area of each heat exchanger m and h must also be reduced, so the number of rows of each heat exchanger m and h must be increased. Therefore, it became necessary to increase the depth dimension of the motor i and the heat exchangers m and h, which increased the cost of both the motor i and the heat exchangers m and h. This results in the opposite of the original purpose of using one fan motor i to make it cheaper, and it cannot be said to be good as a ventilation structure.

きる形状にできなかつた。 In other words, since we are prioritizing the configuration in which two fans o and j are attached to both ends of one motor i within a limited box as described above, the shapes of the suction side and the blowout side of Shirotskov fan o and propeller fan j are It was not possible to create a shape that would allow these fans o and j to operate with low noise.
以上のように、従来の構造は必然的に大騒音が
発生したり、大容量のモータが必要となるなどの
問題があつた。 As described above, the conventional structure inevitably has problems such as generating a large amount of noise and requiring a large-capacity motor.

The purpose of the present invention is to provide an air conditioner with low noise and a small required motor output by smoothly ventilating the ventilation system passage and reducing bends.

部を仕切板に固定したものである。Structure of the Invention In order to achieve this object, the present invention independently provides an outdoor fan and an outdoor fan motor that drives the outdoor fan, and an indoor once-through fan and an indoor fan motor that drives the once-through fan. The inner heat exchanger is made up of a large number of fins stacked at predetermined intervals and a circular tube that passes through the fins in the stacking direction, and the central part is bent at an almost right angle so that the stacked fins at both ends approach each other.
This indoor heat exchanger is arranged so that one straight part is on the indoor side and the other straight part is on the side, and is parallel to the bending axis of the indoor heat exchanger. and the once-through fan is provided on the indoor straight section of the indoor heat exchanger, the indoor end of the indoor heat exchanger is fixed to the stabilizer of the once-through fan, and The side edges are fixed to the partition plate.

のである。 With this configuration, the front surface area of the indoor heat exchanger is widened and the number of through-hole rows of circular pipes is shortened, reducing ventilation resistance.Furthermore, a once-through fan is used on the indoor side, and the suction air flow of the once-through fan is radial. By bending the heat exchanger into an L-shape and surrounding it on the suction side of the once-through fan, the fins are arranged along the inflowing airflow, and the heat exchanger is arranged in an L-shape so as to surround the suction side of the once-through fan. It has less unnecessary contraction, expansion, and bending.

４２とスタビライザ４０からなる通風路を通り、
前面グリル２の吹出し口７から吹出されていく。 In the above configuration, the flow of air when the indoor fan motor 30 is operated will be explained. First, by operating the electrical component operation switch 47, the indoor fan motor 3
0 is operated, the once-through fan 29 attached to the shaft of the indoor fan motor 30 rotates. As a result, in the indoor ventilation system passage 19, the air sucked in from the suction port 6 of the front grille 2 passes through the indoor heat exchanger 28 with a substantially uniform wind speed distribution as shown by the arrow in FIG. passes through a ventilation path consisting of an air guider 42 and a stabilizer 40,
The air is blown out from the air outlet 7 of the front grille 2.

ため、スタビライザ４０の効果が十分発揮され、
偏心渦が安定して貫流フアン２９の通風効率が大
きくなる。 At this time, as a characteristic of the once-through fan 29, an eccentric vortex is generated inside the once-through fan 29 due to the stabilizer 40. Since it is sufficiently larger than the distance B between the part and the cross-flow fan 29, the effect of the stabilizer 40 is fully exhibited.
The eccentric vortex is stabilized and the ventilation efficiency of the cross-flow fan 29 is increased.

大きいものとなる。 Next, a case will be described in which the air conditioner is brought into a cooling operation state by operating the electric component operation switch 47. In addition to the indoor fan motor 30 being driven as described above, the compressor 59 and the outdoor fan motors 55 and 56 are also driven. At this time, in the outdoor ventilation system path 20, as shown by the arrows in FIG. The wind passes through the rear air outlet 1 through the propeller fan air guide 58 by the propeller fans 53 and 54.
It starts blowing out from 5 onwards. Further, the high temperature gaseous refrigerant discharged from the compressor 59 is sent to the outdoor heat exchangers 51 and 52 as condensers, and after being cooled by the air passing through the outdoor heat exchangers 51 and 52, Passing through the stop valves 70 and 71, the main capillary tube 72,
73, the pressure is reduced, and the air is sent to the indoor heat exchanger 28, which serves as an evaporator. Indoor heat exchanger 2
The gas-liquid mixed refrigerant in the indoor heat exchanger 28
is efficiently heated by the uniformly flowing wind, becomes gaseous, and returns to the compressor 59. At this time, since the wind speed of the air passing through the indoor heat exchanger 28 becomes uniform, the refrigerant evaporates evenly, preventing the fins 22 from drying out locally, and covering almost the entire front area. Moisture in the air is condensed and the amount of dehumidification becomes large.

能が向上する。 The indoor heat exchanger 28 has a shape that surrounds the once-through fan 29, and while the intake air flows radially from the surroundings toward the center of the once-through fan 29, the direction of the fins 22 is along that direction, which is different from the conventional one. As compared to the structure in which a rectangular parallelepiped indoor heat exchanger is disposed on the suction side of the Sirotskov fan, noise can be reduced, the efficiency of the once-through fan 29 can be improved, and the input to the indoor fan motor 30 can be reduced. . Furthermore, the indoor heat exchanger 28
The heat exchange performance improves because the air velocity distribution becomes uniform.

果が発揮され、安定した空気流が生じる。 Since the distance A between the left side linear portion of the indoor heat exchanger 28 and the once-through fan 29 is sufficiently larger than the distance B between the front grill side straight portion and the once-through fan 29, the effect of stabilizing the eccentric vortex of the stabilizer 40 is exhibited. This creates a stable airflow.

Not only does it allow effective use of walls, but it also does not impede sunlight from windows.

調和機が低材料費にて実現できる効果を奏する。Effects of the Invention As is clear from the above embodiments, in the integrated air conditioner of the present invention, the indoor heat exchanger is formed in an L-shape. The fins are arranged radially in line with the characteristics of the airflow that flows approximately radially around the axis of the once-through fan within an angular range of approximately 90° from the position closest to the fan, allowing the airflow to flow smoothly without turbulence. As a result, compared to conventional methods such as using a Sirotskov fan as an indoor fan or installing a linear heat exchanger on the suction side of a once-through fan, the noise is lower and the air volume is larger, allowing for more heat. The heat exchange performance of the exchanger can be improved,
An all-in-one air conditioner with low noise, large air volume, and small front surface area is effective at low material costs.
