DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner unit which can be used as an indoor unit of an air conditioner, and more particularly to a position control technique for stopping operation of a blade provided at an air outlet.

[0002]

2. Description of the Related Art Conventionally, an air conditioning unit generally includes a heat exchanger, a blower, and the like housed in a casing having a suction port and an air outlet formed therein. It is configured to heat or cool with a heat exchanger and blow out from the outlet.

In recent years, an air conditioning unit that blows air at a wide angle has been proposed to improve comfort. For example,
As disclosed in JP-B-63-15494, one turbo fan is disposed in a casing so that the rotation axis is vertical, and a heat exchanger covers the front side and the side of the turbo fan. While being arranged in a substantially U-shape, while sucking room air from the lower surface of the rectangular parallelepiped casing,
There has been proposed an indoor unit of a ceiling-suspended type air conditioner that blows out conditioned air from a front surface and both side surfaces of a casing.

[0004]

However, in the above indoor unit that blows air from the front and side surfaces, air cannot be blown out from the corners extending from the front surface to the side surfaces, so that air is spatially continuous over a wide range in the horizontal direction. Can't blow it out. Therefore, the present inventor studied a mode in which an air outlet is provided also in a corner portion and air is blown at a wide angle over the front, the corner portion, and the side.

[0005] By the way, in general, at the air outlet,
In many cases, horizontal blades for guiding the blown air are provided. Therefore, it is preferable to provide a horizontal blade at each of the front outlet, the corner outlet, and the side outlet. It is also preferable that the horizontal blades be manually or automatically rotated around a horizontal axis so that the blowing angle of the blowing air can be adjusted as desired.

However, if all the horizontal blades are configured to be rotatable, the structure of the unit becomes complicated and the cost is increased. Therefore, while the horizontal blades at the front and side outlets with a large amount of air blowing are movable blades, the horizontal blades at the corners at the corners with a small amount of air blowing are fixed blades. It was considered preferable from both viewpoints of cost reduction.

However, it has been found that such a configuration has the following problems. That is, in the above configuration, if the stop position of the movable blade is not controlled when the operation is stopped, the movable blade and the fixed blade are in a discontinuous state, and the appearance is deteriorated. In other words, if the corner outlet is formed to be adjacent to the front outlet in order to improve the air blowing performance, the discontinuity between the movable blade and the fixed blade at the time of stoppage of operation is determined. The line can cause user discomfort and impair comfort in a broader sense.

The present invention has been made in view of the above points, and an object of the present invention is to provide a blade stop position control means for improving the appearance of an air conditioning unit that blows air at a wide angle. It is in.

According to the above, the air sucked in from the suction port (41) is heated or cooled when passing through the heat exchanger (30) to become conditioned air, and the front air outlet (43) and both corner air outlets are provided. It is blown out from (42). Therefore, the conditioned air is blown over a wide area, and the comfort is improved. When the operation is stopped, the stop position control means (86) causes the front air outlet (4

1,82), the appearance of the front outlet (43) and both corner outlets (42) is improved, and user discomfort is eliminated.

The casing (10) is formed with side air outlets (44) that open on both sides so as to be adjacent to or continuous with the corner air outlets (42) on both sides, and each fixed blade (82) Bending from the front side to the rear side along each corner outlet (42), the blower (20R, 20L) passes air introduced from the inlet (41) through the heat exchanger (30) and the front outlet. (43), it is configured to generate an air flow derived from both corner outlets (42) and both side outlets (44), and each side outlet (44) Side blades (83) extending rearward along the side outlets (44) may be provided.

According to the above, the conditioned air is supplied to the front outlet (4
3), the air is blown out from both corner outlets (42) and both side outlets (44), and the outlet angle of the conditioned air is increased. Therefore, comfort is further improved. The side blade (83) may be a fixed blade (82) provided in the corner outlet (42) and may be a fixed blade that is linearly continuous with the fixed blade (82), or a movable blade that rotates manually or automatically. It may be. Since the side outlet (44) is less noticeable than the front outlet (43) and the corner outlet (42), even if the side blade (83) is not linearly continuous with the fixed blade (82). However, there is little risk of causing user discomfort.

Each of the side blades (83) is rotatably supported, and a stop position control means (86, 87) controls the side blades (83) to be fixed to the fixed blade (82) when the operation is stopped. It may be configured to rotate to a linearly continuous stop position and to hold each of the side blades (83) at the stop position.

According to the above, since the side blades (83) are rotatable, the blowing direction of the conditioned air blown from the side can be changed, and the comfort is further improved. When the operation is stopped, the side blades (83) are rotated to a position that is linearly continuous with the fixed blades (82) of the corner outlets (42).
Because it keeps its position, the side blade (83) and the fixed blade (82)
And the appearance is further improved. Therefore, the comfort of the user can be further improved.
