BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner.

[0002]

2. Description of the Related Art In recent years, interior decoration has come to be emphasized even in individual houses, and even in the case of an air conditioner indoor unit, simply performing air conditioning is not satisfactory, and a smarter and more indoor-looking appearance is achieved. There is a strong demand for what we have. Therefore, in order to meet such a demand, for example, an indoor unit as shown in FIG. 4 has been devised. In the case of this indoor unit, the main body 21
The front surface of the is finished to be flat to improve its appearance, and the suction port 22 is formed in the upper portion of the main body 21. At the bottom of the suction port 22, there is an air filter 23 which can be attached and detached along the inner surface, and at the upper part of the air passage 25 which connects the suction port 22 and the air outlet 24 at the lower part of the main body, heat formed in an inverted V shape. A heat exchanger 26 is provided, a fan 27 is arranged below the heat exchanger 26, and an air flow direction plate 28 is provided at the air outlet 24 at the lower part of the main body to adjust the air flow direction into the room.

[0003]

By the way, in the above-mentioned indoor unit, the heat exchanger 26 is formed in an inverted V shape, so that it is better than the indoor unit having the upright type heat exchanger before that. For example, the height of the main body 21 is reduced by the amount by which the upper portion of the heat exchanger 26 is bent, and the size is reduced.
However, as described above, merely forming the heat exchanger 26 in the inverted V shape and arranging the heat exchanger 26 has a limit for further miniaturization. If the size cannot be further reduced, there are problems that it is difficult to mount it in a narrow place, it does not match the interior in terms of appearance, and the cost cannot be sufficiently reduced. Therefore, an object of the present invention is to solve these problems and provide a more compact indoor unit for an air conditioner.

[0004]

The present invention has been made to solve the above-mentioned problems, and connects a suction port formed in the upper part of the main body and an air outlet formed in the lower part of the main body. In an indoor unit of an air conditioner in which an air filter, a heat exchanger, a fan, etc. are arranged in a blower path, the heat exchanger is horizontally divided into three parts at a ratio of 2: 3: 2 and two adjacent The heat exchanger was bent into an inverted V shape, and the other heat exchanger was folded in three so as to be almost upright, and the fan was placed in the heat exchanger that was folded in three.

[0005]

With the above structure, the heat exchanger arranged in the air passage is divided into three parts in the horizontal direction at a ratio of 2: 3: 2, and two adjacent heat exchangers are bent into an inverted V shape. The remaining heat exchanger is folded in three so that it is almost upright, so the vertical dimension can be reduced without changing the overall size of the heat exchanger. Since the heat exchanger is placed in the heat exchanger, the vertical dimension can be further reduced, and the vertical dimension of the indoor unit can be further reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an external perspective view of an indoor unit. Reference numeral 1 denotes a main body, which is a housing 2 and a front cover 3 provided from the upper rear side of the housing 2 to the lower front surface.
The front surface 3a of the front cover 3 is rotatably supported by the upper portion so that it can be opened and closed. Further, a suction port 4 for indoor air is provided in the upper part of the front cover 3, and a blowout port 5 is formed in the lower part.

FIG. 2 is a vertical side view of the indoor unit.
An air passage 6 is formed between the suction port 4 and the air outlet 5, and the air passage 6 is moved along the inner surface of the front cover 3 to the upper rear portion of the housing 2. The detachable air filter 7, the heat exchanger 8 bent in three, and the fan 9 are arranged, and the air heat-exchanged by the heat exchanger 8 is sent to the outlet 5 by the fan 9. The wind direction into the room is adjusted by the wind direction plate 10. In the figure, 11 and 12 are a dew receiving part for receiving defrosting water falling along the heat exchanger 8 and a wall forming a part of the air passage 6 at the same time.

FIG. 3 is a perspective view of the heat exchanger 8. Needless to say, the fins 13 and the fins 13 that are stacked are stacked.
It is composed of a heat transfer tube 14 which is passed through and a fitting 15 and the like.
The fins 13 are provided with slits (not shown) for dividing the heat exchanger 8 into three in the horizontal direction at a ratio of 2 to 3 to 2, and after being assembled as a heat exchanger, 8a, 8
It is divided into three parts, b and 8c. At the time of this division into three, the two adjacent heat exchangers 8b and 8c are bent so as to form an inverted V shape (roof shape), and the remaining heat exchanger 8a is folded in three so as to be almost upright. To be

The heat exchanger 8 thus folded in three is arranged above the air passage 6 as shown in FIG. The fan 9 is arranged in the center of the heat exchanger 8 which is folded in three,
At this time, the bent portions of the heat exchangers 8b and 8c formed in the inverted V shape are almost directly above the rotation axis of the fan 9. Further, the heat exchangers 8b and 8c are arranged so that the inclination angles thereof are substantially equal to each other. With such a configuration, the vertical dimension of the main body 1 can be reduced, and the heat exchangers 8a, 8b,
Since the distance difference between the 8c and the fan 9 is reduced, the wind speed distribution is also improved. Furthermore, since the distance from the fan 9 to the outlet 5 can be made long, the wind force toward the outlet 5 can be strengthened.

[0010]

As described above, if the indoor unit is constructed as described above, the original performance is not deteriorated,
It is more compact and can be easily installed in the room, and it is possible to expect cost reduction due to miniaturization.
