DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner provided with a wind direction adjusting mechanism for deflecting a wind flow generated by a blower source and blown out from an outlet of an indoor unit or the like in arbitrary directions of up, down, left and right.

[0002]

2. Description of the Related Art Conventionally, this type of air conditioner is roughly divided into an indoor unit and an outdoor unit, or an air conditioner in which all components are integrated into one casing. There are various types of models, but all of them have a wind direction adjusting mechanism for adjusting the directivity of an air flow at an outlet for blowing air of which temperature and humidity are adjusted toward a room.

FIG. 6 shows a wall-mounted type indoor unit in a separation type air conditioner as an example of the prior art.
At the lower end of the indoor unit 21 shown in this figure, a horizontally long outlet 22 is provided. FIG. 7 schematically shows an enlarged vertical cross section of the outlet 22 and its periphery. In FIG. 7, the outlet 22 is a cross flow fan 2 as a blowing source.
3 communicates with the ventilation passage 24 provided with the fan 2.
3 is formed in a shape having a required depth so as to function as a runway for directing the wind flow generated obliquely downward.

A plurality of vertical louvers 25 are arranged at the back end of the outlet 22 so as to be rotatable by a predetermined angle around the vertical axis in a state of being arranged in a line at substantially equal intervals. The airflow blown out from the outlet 22 is given a directivity in the left-right direction by appropriately rotating and displacing the 25 in a desired direction.

On the other hand, a single horizontal louver 26 having a length substantially corresponding to the entire length of the air outlet 22 is provided at the outlet end so that one end thereof can be displaced by a predetermined angle about a horizontal axis. By rotating and displacing the louver 26 in an arbitrary direction according to a difference between cold air, hot air, or the like, or according to a user's judgment,
Vertical directionality is given to the wind.

For example, as shown by a solid line in FIG.
When the airflow is inclined such that the airflow 6 faces the air outlet 22, the airflow blows downward as indicated by an arrow F <b> 8. It blows out slightly downward as indicated by arrow F9.

FIG. 8 schematically shows an enlarged vertical section of the outlet 22 and its surroundings in another conventional example. In the drawing, the movable vertical louver 25 having the directivity in the left and right direction of the air flow has the same configuration and operation as the conventional example, but the movable horizontal louver 25 has the directivity in the vertical direction of the air flow. Two louvers 26a and 26b are provided at the outlet end of the outlet 22 at predetermined intervals vertically. FIG. 9 shows a state in which the posture of the lower horizontal louver 26b is displaced.

[0008] As shown in FIG.
In a posture in which both a and 26b are laid down substantially horizontally, the air flow blows out in a substantially horizontal direction as indicated by an arrow F10. Further, as shown in FIG. 9, when the upper horizontal louver 26a is held in a horizontal posture and the lower horizontal louver 26b is rotated and displaced to a substantially vertical posture, the air flow blown out from the outlet 22 is indicated by an arrow F11. As described above, the air flow is divided into a wind flowing forward along both sides of the upper horizontal louver 26a and a wind flowing downward along the lower horizontal louver 26b as indicated by an arrow F12.

Further, as another conventional example, as disclosed in Japanese Utility Model Laid-Open No. 61-84442, for example, the point that two movable lateral louvers are provided at the outlet is described in FIGS. However, in the case of horizontal blowing, the two louvers are overlapped with each other, and in the case of downward blowing, the two louvers are positioned in parallel to efficiently deflect the air flow. Some of them are also known.

[0010]

In the prior art shown in FIG. 7, since a single horizontal louver 26 is used to give the wind current directivity in the vertical direction, the wing surface of the horizontal louver 26 is used. Even if the width is formed to be substantially the same as the vertical width of the air outlet 22, it can be accommodated in the air outlet 22, so that the wide lateral louvers 27 can provide the necessary directivity to some extent. Because you ca n’t
It can only be blown out in one direction up and down.

For this reason, there is a problem in that a large amount of warm air is blown to a person indoors during heating to cause discomfort. Such a problem is not possible even in the other conventional examples disclosed in the above-mentioned publications,
It can happen as well.

In the other conventional example shown in FIGS. 8 and 9, it is considered that the blowout direction of the air flow can be divided into two arbitrary directions by the two lateral louvers 26a and 26b. The horizontal louvers 26a and 26b are at the outlet 22
Are stored substantially vertically in the vertical width direction, so that the width of the wing surface of both the horizontal louvers 26a and 26b cannot be increased. For this reason, the directivity of the wind current cannot be obtained sufficiently, so that the air conditioning in the room is not evenly performed,
There is a problem that an airflow in a desired direction cannot be sufficiently obtained.

The present invention solves such a problem in the prior art, and it is possible to not only divide the airflow, but also to impart a stable directivity to the diverted airflow, thereby providing indoor air. It is an object of the present invention to provide an air conditioner having an excellent wind direction adjusting function capable of performing uniform harmony or obtaining a sufficient airflow in a desired direction.

[0014]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an air conditioner body having a horizontally long outlet having a required depth.
In an air conditioner provided with a plurality of wind direction louvers,
The wind louvers are separated from each other by a plurality of different postures in which the wing surfaces are separated from each other, and
It is configured such that the posture can be shifted to a storage posture in which the storage postures are overlapped in a right angle state or close to each other in the right angle state .

[0015] In the above configuration, in one of the plurality of postures for performing the airflow directing action, one wind direction louver positioned closer to the upper surface of the outlet and the other wind direction louver positioned closer to the lower surface of the outlet in the same posture. The configuration can be such that one wind direction louver is housed inside the other wind direction louver or vice versa.

It is preferable that one end of one wind direction louver is pivotally supported near the upper surface of the air outlet so as to be rotatable, and one end of the other wind direction louver is preferably pivotably supported near the lower surface of the air outlet.

[0017] Further, when at least the lower surface of the air outlet is formed in the airflow runway, at least one of the wind direction louvers can be displaced to a position located on an extension surface of the airflow runway, In the case where a flat wall surface having a short vertical dimension is continuously formed downward from the opening end of the outlet, the wing surface of the wind direction louver near the flat wall is formed longer than the vertical width dimension of the flat wall, In addition, the posture can be changed to a position overlapping the flat wall surface.

Preferably, the wind direction louver near the flat wall surface is configured to be movable between a position where a wing surface is on an extension surface of the airflow runway and a position where the blade surface overlaps the flat wall surface.

[0019]

According to the above construction, the direction of the air flow blown out from the outlet can be arbitrarily deflected by independently changing the attitude of the two wind direction louvers. In this case, by displacing the wind direction louver located near the upper surface of the outlet to a required posture, the wind current can be divided into a vertical flow and a vertical flow.

Further, the two wind direction louvers overlap with each other in a state where their wing surfaces are at right angles to the wind blowout direction, or at right angles.
In this state, the louvers are stored in a position facing each other, so that the width of the wing surface of the wind direction louver can be increased to approximately the same as the vertical width of the air outlet, if necessary, thereby improving the directivity of the air flow. Can be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in FIGS. 1 to 4 applies the present invention to an air conditioner having a wall-mounted indoor unit similar to that shown in FIG. FIGS. 1 to 4 each show a vertical section of the indoor unit, and each figure shows a state in which two movable lateral louvers described later are displaced to different postures.

In FIG. 1, reference numeral 1 denotes an indoor unit casing as an air conditioner main body, in which front and rear walls 2, 3 formed in a required shape are disposed facing each other. A ventilation path 4 is formed between the front and rear walls 2, 3. The ventilation path 4 is continuous with a horizontally long blow-off port 5 having a required depth and opened at the lower end of the casing 1. A cross-flow fan 6 as a blowing source disposed in the center of the ventilation path 4 serves as a ventilation source. The drafted wind is the ventilation path 4
Through the air outlet 5 to be blown into the room.

The peripheral wall forming the outlet 5 has a flat upper wall 7 connected to the lower end of the front wall 2 and a flat lower wall 8 connected to the rear wall 3. Both the upper and lower walls 7 and 8 are formed as parallel gentle inclined walls which are directed downward toward the front, and the upper wall 7 has a length reaching the vicinity of the cross flow fan 6. Thereby, the wall surfaces of the upper and lower walls 7 and 8 are configured to function as a runway that directs the wind generated by the fan 6 obliquely downward.
End face of lower wall 8 facing the outlet end of outlet 5 and casing 1
Between the bottom wall 9 and the flat vertical wall 1 having a short vertical dimension.
0 is continuously formed on the lower wall 8 and the bottom wall 9.

A plurality of vertical louvers 11 are arranged at the back end of the outlet 5 so as to be displaceable by a predetermined angle around the vertical axis in a state of being arranged in a line at substantially equal intervals. By rotating and displacing the louver 11 in a desired direction by a suitable operation means, the airflow blown out from the outlet 5 is given a directivity in the left-right direction.

Further, the outlet 5 is provided at the outlet end side of the outlet 5.
The upper and lower two horizontal louvers (corresponding to the wind direction louvers) 12 and 13 having a length almost the entire length are provided. The upper lateral louver 12 has a blade surface width shorter than the vertical width of the air outlet 5, and one end thereof can be pivotally displaced by a predetermined angle to a horizontal pivot 14 provided near the upper wall 7. Is pivoted to. On the other hand, the lower lateral louver 13 has a wing surface width longer than that of the upper lateral louver 12 and is formed to have a length enough to fit into the outlet end of the air outlet 5, and the pivot bracket 13b provided at one end thereof is provided. It is pivotally supported by a horizontal pivot 15 provided in the vicinity of the lower wall 8 through a predetermined angle so as to be rotatable by a predetermined angle.

The lateral louvers 12, 13 are controlled by, for example, appropriate drive operating means to rotate and displace in the directions indicated by arrows a and b according to a preset program to take a plurality of different postures. .

That is, in FIG.
Are located inside the lower lateral louver 13 and both 12, 1
3 wing surfaces 12a and 13a are perpendicular to the wind
In this state, it is housed at the outlet end of the outlet 5 in a posture facing closely. In this storage state, both 12 and 13 are used.
May be superimposed on each other.

As described above, in this embodiment, since the wing surfaces 12a and 13a of the two lateral louvers 12 and 13 are housed in a posture facing each other, the lower lateral louver 1 is provided.
The width of the wing surface 3 can be made substantially the same as the vertical width of the air outlet 5, thereby improving the directivity of the air flow.

In FIG. 2, the upper horizontal louver 12 has been rotated and displaced until it is in a horizontal position.
A horizontal branch passage 16 is formed between the wing surface 12a and the upper surface of the air outlet 5 to allow the air flow to be blown out. On the other hand, the lower lateral louver 13 is rotationally displaced so that its wing surface 13a is located on an extension plane of the wall surface of the lower wall 8 constituting the approach path.

In this case, the upper and lower horizontal louvers 12 and 13 are divided into upper and lower sides of the air outlet 5 and both protrude outward. The air flow generated by the cross flow fan 6 is divided by the upper horizontal louver 12. Is done. The upper airflow F1 flows horizontally in the horizontal branch passage 16 along the blade surface of the upper lateral louver 12, and the lower airflow F2 flows in the direction following the ventilation passage 4.
At this time, since the wing surface 13a of the lower lateral louver 13 coincides with the wall surface of the lower wall 8 of the ventilation path 4, the approach path is eventually extended, and the directivity of the airflow is improved. Therefore, the flow can be stabilized.

In FIG. 3, the upper horizontal louver 12 is rotated and displaced until the upper horizontal louver 12 is in an inclined position parallel to the upper wall 7, and a wind current flows between the wing surface 12 a of the upper horizontal louver 12 and the upper surface of the air outlet 5. Is formed. On the other hand, the lower horizontal louver 13 is rotationally displaced until the wing surface 13a thereof is in a substantially downward posture at a position overlapping the vertical wall 10.

In this case, since the upper lateral louver 12 projects obliquely forward of the outlet 5 and the lower lateral louver 13 hangs below the outlet 5, the airflow blown by the cross flow fan 6 is: The airflow is divided by the upper lateral louver 12, and the upper inclined wind flow F <b> 3 flows through the inclined branch passage 17 along the blade surface 12 a of the upper lateral louver 12.

At this time, the lower horizontal louver 13 overlaps the vertical wall 10 and its wing surface is longer than the vertical wall 10, so that the vertical wall 10 has an enlarged shape and the lower wind flow F4 Directivity is improved, and it is possible to efficiently diverge into a downward blow or a horizontal flow and a downward flow.

In FIG. 4, the upper lateral louver 12 is rotationally displaced so as to face the outlet 5 until it is in a lowered position, and the upper lateral louver 12 has a surface 12b substantially orthogonal to the wing surface 12a of the upper lateral louver 12. A horizontal branch passage 18 is formed between the upper surfaces of the air outlets 5 so as to allow air to flow out. On the other hand, the lower horizontal louver 13 is configured to take both the attitude that the wing surface of the lower lateral louver 13 and the attitude where the wing surface overlaps the vertical wall 10 is almost drooped similarly to the attitude of FIG.

In this case, the air flow F5 generated by the cross flow fan 6 is split by the upper horizontal louver 12, and the upper horizontal air flow F5 is separated from the blade surface 12a of the upper horizontal louver 12.
Flows through the horizontal branch passage 18 along a surface 12b substantially orthogonal to the horizontal direction.

On the other hand, the lower wind louver F6 is blown downward along the wing surface 13a of the lower horizontal louver 13, with the direction of the blowout being regulated by the upper horizontal louver 12 and the lower horizontal louver 13. In this way, by being divided into the upper horizontal airflow F5 and the lower airflow F6, the inconvenience that all the warm air blown out from the outlet 5 hits a person in the room during heating is avoided,
Discomfort due to this can be prevented. Further, by moving the lower lateral louver 13 to a position where the wing surface 13a is located on the wall extension of the lower wall 8 as shown by a broken line,
The lower airflow can be arbitrarily adjusted from F6 to F7.

In the present invention, as shown in FIG. 5, the lower horizontal louver 13 may be housed inside the upper horizontal louver 12, contrary to the above embodiment. In either configuration, the upper and lower horizontal louvers 12, 13 are connected to the wing surfaces 12a,
13a can be accommodated at the outlet end of the outlet 5 in an overlapping state, so that the width of the wing surface of the lateral louvers 12, 13 can be increased, and the directivity in the direction of airflow can be enhanced.

In the above embodiment, both lateral louvers 1 are used.
2 and 13 are both configured to be displaced about horizontal pivots 14 and 15;
The postures of 2 and 13 may be displaced using a link mechanism or the like.

[0039]

As described above, according to the present invention, when two wind louvers arranged along the longitudinal direction of the air outlet are stored, their wing surfaces are in the same direction as the air flow blowout direction.
Since it is possible to be in a posture of overlapping at a right angle or facing the near and near at the right angle, the wing surface width of the wind direction louver should be as large as approximately the upper and lower width of the air outlet as necessary. Thus, the directivity of the wind current can be improved.

According to the fifth aspect, since the wing surface of the wind direction louver can be displaced to a position located on an extension surface of the airflow runway formed in the air outlet, the runway is extended as a result. As a result, the directivity of the wind current can be improved and the flow can be stabilized.

According to the present invention, the width of the louver of the wind direction louver is made longer than that of a flat wall having a short vertical dimension formed downward from the opening end of the air outlet, and the wind direction louver is flattened. Since the posture can be displaced to a position overlapping with the wall surface, in this case, the flat wall surface has an enlarged shape, and can efficiently diverge into a downward blow or a horizontal and downward flow.

According to the seventh aspect, since the wing surface of the wind direction louver can be moved between a position on the extended surface of the airflow runway and a position overlapping with the flat wall surface, the flow is divided by the other wind direction louver. The lower wind current can be easily changed.
