Abstract

PURPOSE:To enable an air flow to be divided into some flows, a stable directing characteristic to be attained and a sufficient comfortable air flow to be got in a desired direction. CONSTITUTION:Upper and lower two lateral louvers 12 and 13 are arranged along a longitudinal direction of an air blowing port 5. These lateral louvers 12 and 13 can be displaced in their attitudes between a plurality of different attitudes with their wing surfaces 12a and 13a being spaced apart to each other to perform an air flow directing action and their storing attitudes in which their wing surfaces 12a and 13a are near to each other and opposed while being opposed against the air blowing direction. With such an arrangement as above, since the two lateral louvers 12 and 13 are stored while being piled up to each other, it is possible to form the louver of length extending over a vertical width of the air blowing port 5, thereby it is possible to improve a directing characteristic of the air flow blowing direction.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, air conditioners of this type are roughly divided into an indoor unit and an outdoor unit, or an air conditioner in which all the components are integrated into one casing. There are various types of models, but all of them are equipped with an air-direction adjusting mechanism for adjusting the directionality of the air flow at the air outlet that blows out the air whose temperature and humidity are adjusted toward the room.

FIG. 6 shows a wall-mounted indoor unit in a separation type air conditioner as an example of the conventional art.
A horizontally long air outlet 22 is provided at the lower end of the indoor unit 21 shown in this figure. FIG. 7 schematically shows an enlarged vertical section of the air outlet 22 and its surroundings. In FIG. 7, a blowout port 22 is a cross flow fan 2 as a blower source.
3 communicates with an air passage 24 provided with the fan 2
It is formed in a shape having a required depth so as to function as a runway for directing the wind flow generated by 3 in a diagonally downward direction.

A large number of vertical louvers 25 are arranged on the rear end side of the blowout port 22 so as to be rotatable about the vertical axis by a predetermined angle while being aligned in a line at substantially equal intervals. By rotatively displacing 25 in a desired direction, the airflow blown out from the outlet 22 is given a directivity in the left-right direction.

On the other hand, on the outlet end side, a single horizontal louver 26 having a length substantially equal to the entire length of the blowout port 22 is disposed so that one end thereof can be pivotally displaced by a predetermined angle around a horizontal axis. By rotatively displacing the louver 26 in an arbitrary direction according to a difference in cold air, warm air, or the like, or by a user's judgment,
The vertical direction is given to the wind flow.

For example, as shown by the solid line in FIG.
In the posture in which 6 is inclined so as to face the air outlet 22, the air flow blows downward as indicated by arrow F8, and in the laid posture in which the horizontal louver 26 is substantially parallel to the upper surface of the air outlet 22 as indicated by the broken line, the air flow is It blows out slightly downward as shown by arrow F9.

FIG. 8 schematically shows an enlarged vertical section of the air outlet 22 and its surroundings in another conventional example. In the structure shown in this figure, the movable vertical louver 25 having the directivity in the horizontal direction of the wind flow has the same configuration and operation as the above-mentioned conventional example, but the movable horizontal louver 25 having the directivity in the vertical direction of the wind flow is provided. Two louvers 26a and 26b are provided at the outlet end of the air outlet 22 at a predetermined interval in the vertical direction. FIG. 9 shows a state in which the posture of the lower lateral louver 26b is displaced.

As shown in FIG. 8, both lateral louvers 26 are
In a posture in which both a and 26b are laid down substantially horizontally, the wind flow blows out in a substantially horizontal direction as indicated by arrow F10. Further, as shown in FIG. 9, when the upper lateral louver 26a is held in a horizontal posture and the lower lateral louver 26b is rotationally displaced in a substantially vertical posture, the air flow blown out from the outlet 22 is indicated by an arrow F11. As described above, it is divided into a wind flow that flows forward along both sides of the upper horizontal louver 26a and a wind flow that flows downward along the lower horizontal louver 26b as indicated by an arrow F12.

Further, as still another conventional example, as disclosed in, for example, Japanese Utility Model Laid-Open No. 61-84442, two movable lateral louvers are provided at the outlet, as shown in FIGS. 8 and 9. Although it is the same as the other conventional example shown in, the two louvers overlap each other in the horizontal blowing, and the two louvers are positioned in parallel in the lower blowing to efficiently deflect the airflow. It is also known to do so.

[0010]

In the conventional example shown in FIG. 7, since the single horizontal louver 26 acts to give the wind flow directivity in the vertical direction, the blade surface of the horizontal louver 26 is reduced. Even if the width is formed to be approximately the vertical width of the blowout port 22, it can be accommodated in the blowout port 22, so that the wide lateral louver 27 can give the necessary directivity to some extent, but the flow is divided. Because I can't
It can only be blown up and down in one direction.

Therefore, there is a problem that a large amount of warm air is blown to a person in the room during heating to cause discomfort. Such a problem is that even in another conventional example disclosed in the above-mentioned publication, diversion is impossible,
It can happen as well.

Further, in the other conventional example shown in FIGS. 8 and 9, it is considered that the blowing direction of the wind flow can be divided into two arbitrary directions by the two lateral louvers 26a and 26b. The lateral louvers 26a and 26b are the air outlets 22.
Since the vertical louvers 26a and 26b are housed substantially vertically in the vertical direction, the wing surface widths of both lateral louvers 26a and 26b cannot be increased. For this reason, the directionality of the wind flow cannot be obtained sufficiently, so that air conditioning in the room is not performed evenly,
There is a problem that the wind flow in the desired direction cannot be obtained sufficiently.

The present invention solves the above-mentioned conventional problems. In addition to being able to divert the airflow, it is also possible to give a stable directivity to the diverted airflow, thereby allowing the indoor air to flow. It is an object of the present invention to provide an air conditioner having an excellent air flow direction adjusting function that can perform harmony evenly or obtain a sufficient air flow in a desired direction.

[0014]

In order to achieve the above-mentioned object, the present invention provides an air conditioner main body with a laterally long air outlet having a required depth, and the air outlet is provided with two longitudinally extending air outlets.
In an air conditioner provided with a sheet of wind direction louvers,
It is possible to change the position of the wind direction louver between a plurality of different postures in which the blade surfaces are separated from each other to direct the air flow, and a storage posture in which the blade surfaces overlap or closely face each other with the blade surfaces facing the air flow blowing direction. I am configuring.

In the above structure, one wind direction louver located closer to the upper surface of the outlet in a plurality of postures for directing the wind flow and the other wind louver located closer to the lower surface of the outlet in the same posture. The configuration may 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 so as to be pivotally displaceable in the vicinity of the upper surface of the air outlet, and one end of the other air flow direction louver is pivotally displaceable in the vicinity of the lower surface of the air outlet.

Further, in the case where at least the lower surface of the air outlet is formed in the wind flow assisting passage, the blade surface of at least one wind direction louver is configured to be displaceable to a posture positioned on the extension surface of the air flow assisting passage. In the case where a flat wall surface having a short vertical width dimension is continuously formed downward from the opening end of the air outlet, the blade surface of the wind direction louver near the flat wall surface is formed longer than the vertical width dimension of the flat wall surface, In addition, it can be configured such that the posture can be displaced to a position overlapping with the flat wall surface.

Further, preferably, the wind direction louver near the flat wall surface is configured to be movable between a position where the blade surface is on an extension surface of the wind flow runway and a position where it overlaps with the flat wall surface.

[0019]

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

Further, since the two wind direction louvers are accommodated in a posture in which the blade surfaces of the two wind direction louvers overlap or closely face each other in a state where their blade surfaces are opposed to the air flow blowing direction, the blade surface width of the wind direction louvers can be adjusted as necessary. The width can be as large as the vertical width, which can improve the directivity of the wind flow.

[0021]

1 to 4, the present invention is applied to an air conditioner having a wall-mounted indoor unit similar to that shown in FIG. 6 above. 1 to 4 each show a vertical cross section of the indoor unit, and in each drawing, a state in which two movable horizontal louvers described later are displaced to different postures is shown.

In FIG. 1, reference numeral 1 denotes an indoor unit casing as an air conditioner main body, in which front and rear walls 2 and 3 each having a desired shape are arranged so as to face each other. A ventilation passage 4 is formed between the front and rear walls 2, 3. The ventilation passage 4 is continuous with a laterally long air outlet 5 having a required depth that opens at the lower end of the casing 1, and a cross flow fan 6 as a ventilation source disposed in the central portion of the ventilation passage 4 is provided. The wind flow created by ventilation 4
Is blown out into the room through the air outlet 5.

The peripheral wall forming the outlet 5 is provided with a flat upper wall 7 connected to the lower end of the front wall 2 and a flat lower wall 8 continuous with the rear wall 3. These upper and lower walls 7 and 8 are both formed as parallel slanted walls that are downward toward the front, and the upper wall 7 has a length reaching up to the vicinity of the cross flow fan 6. As a result, the wall surfaces of the upper and lower walls 7 and 8 are configured to function as a runway that directs the airflow generated by the fan 6 obliquely downward.
The end face of the lower wall 8 facing the outlet end of the outlet 5 and the casing 1
Between the bottom wall 9 and the bottom wall 9 of the flat vertical wall 1
0 is formed continuously on the lower wall 8 and the bottom wall 9.

A large number of vertical louvers 11 are arranged on the rear end side of the air outlet 5 so as to be rotatable about the vertical axis by a predetermined angle in a state of being aligned in a line at substantially equal intervals. By rotating and displacing the louver 11 in a desired direction by an appropriate operating means, the wind flow blown out from the outlet 5 is given a directivity in the left-right direction.

Further, on the outlet end side of the outlet 5, the outlet 5
Two upper and lower horizontal louvers (corresponding to the wind direction louvers) 12 and 13 each having a length substantially equal to the entire length are provided. Of these, the upper lateral louver 12 is formed such that its wing surface width is shorter than the vertical width of the outlet 5, and one end of which is pivotally displaceable by a predetermined angle on a horizontal pivot 14 provided near the upper wall 7. Is pivoted to. On the other hand, the lower lateral louver 13 has a blade surface width that is longer than that of the upper lateral louver 12 and is formed to a length that can be accommodated in the outlet end of the air outlet 5, and the pivot bracket 13b provided at one end thereof is It is rotatably supported by a horizontal pivot 15 provided near the lower wall 8 by a predetermined angle.

The lateral louvers 12 and 13 are controlled by, for example, appropriate driving operation means so as to be rotationally displaced in the directions indicated by arrows a and b in accordance with a preset program to take a plurality of different postures. .

That is, in FIG. 1, the upper lateral louver 12 is
Is located inside the lower lateral louver 13, and both 12, 1
The wing surfaces 12a and 13a of No. 3 are housed at the outlet end of the air outlet 5 in a posture of facing each other in a state of facing each other in the air flow blowing direction. In this stored state, the blade surfaces 12a and 13a of the both 12 and 13 may overlap each other.

As described above, in this embodiment, since the blade surfaces 12a and 13a of the two lateral louvers 12 and 13 are housed in a posture in which they face each other closely, the lower lateral louver 1
It is possible to make the blade surface width of No. 3 as large as the vertical width of the air outlet 5 and thereby improve the directivity of the wind flow.

In FIG. 2, the upper lateral louver 12 is rotationally displaced until it assumes a horizontal posture.
A horizontal shunt passage 16 is formed between the blade surface 12a and the upper surface of the air outlet 5 to allow the blowing of the wind flow. On the other hand, the wing surface 13a of the lower lateral louver 13 is rotationally displaced such that the wing surface 13a thereof is positioned on the extension plane of the wall surface of the lower wall 8 forming the approach passage.

In this case, the upper and lower horizontal louvers 12 and 13 are divided into upper and lower sides of the outlet 5 and both project outward, and the air flow generated by the cross flow fan 6 is diverted by the upper side louver 12. To be done. The upper wind flow F1 flows horizontally in the horizontal branch passage 16 along the blade surface of the upper lateral louver 12, and the lower wind flow 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 passage 4, the runway is consequently extended, and the directivity of the wind flow is improved. Therefore, the flow can be stabilized.

In FIG. 3, the upper lateral louver 12 is rotationally displaced until it is in an inclined posture parallel to the upper wall 7, and the air flow is generated between the blade surface 12 a of the upper lateral louver 12 and the upper surface of the air outlet 5. An inclined shunt passage 17 is formed to allow the blowout of. On the other hand, the lower lateral louver 13 is rotationally displaced until its wing surface 13a overlaps the vertical wall 10 and assumes a substantially drooping posture.

In this case, since the upper lateral louver 12 projects obliquely forward of the air outlet 5 and the lower lateral louver 13 hangs down below the air outlet 5, the airflow generated by the cross flow fan 6 is The upper side louver 12 divides the upper side louver 12, and the upper side inclined wind flow F3 flows along the blade surface 12a of the upper side louver 12 through the inclined branch flow passage 17.

At this time, since the lower lateral louver 13 overlaps the vertical wall 10 and the blade surface thereof is longer than the vertical wall 10, the vertical wall 10 has an enlarged shape, and the lower wind flow F4 The directivity can be improved and the air can be efficiently discharged downward, or can be divided into a horizontal flow and a downward flow.

In FIG. 4, the upper lateral louver 12 is rotationally displaced until it hangs down so as to face the air outlet 5, and a surface 12b substantially orthogonal to the blade surface 12a of the upper lateral louver 12 is formed. A horizontal branch passage 18 is formed between the upper surfaces of the outlets 5 to allow the airflow to be blown out. On the other hand, the lower lateral louver 13 is configured to have both a posture in which the wing surface thereof substantially hangs down at a position where it overlaps with the vertical wall 10 as in the posture in FIG.

In this case, the wind flow F5 generated by the cross flow fan 6 is split by the upper horizontal louver 12, and the upper horizontal wind flow F5 is the blade surface 12a of the upper horizontal louver 12.
Flows in the horizontal diversion passage 18 along a surface 12b that is substantially orthogonal to.

On the other hand, the lower wind flow F6 has its air flow blowing direction restricted by the upper lateral louver 12 and the lower lateral louver 13, and blows downward along the blade surface 13a of the lower lateral louver 13. In this way, by being divided into the upper horizontal airflow F5 and the lower airflow F6, it is possible to avoid the inconvenience that all the warm air blown out from the air outlet 5 hits the person in the room during heating,
Discomfort caused thereby can be prevented. Further, by moving the lower lateral louver 13 to a posture in which the wing surface 13a is positioned on the wall surface extension of the lower wall 8 as shown by the broken line,
The lower wind flow can be adjusted arbitrarily from F6 to F7.

In the present invention, as shown in FIG. 5, the lower lateral louver 13 may be housed inside the upper lateral louver 12, contrary to the above embodiment. In either configuration, the upper and lower lateral louvers 12, 13 are connected to the wing surface 12a,
Since they can be housed in the outlet end of the blow-out port 5 with 13a overlapping, the blade surface width of the lateral louvers 12, 13 can be made large, and the directivity in the air flow blowing direction can be enhanced.

In the above embodiment, both lateral louvers 1 are used.
Both 2 and 13 are constructed so as to be rotationally displaced about the horizontal pivots 14 and 15, but in addition, for example, the lateral louver 1
The postures of 2 and 13 may be displaced by using a link mechanism or the like.

[0039]

As described above, according to the present invention, when the two wind direction louvers arranged along the longitudinal direction of the air outlet are housed, their blade surfaces face each other in the air flow blowing direction. In this state, the louvers can be placed in a posture of overlapping or closely facing each other, so that the wing surface width of the wind direction louver can be made as large as the vertical width of the air outlet if necessary, thereby improving the directionality of the wind flow. Can be made.

According to the present invention, since the blade surface of the wind direction louver can be displaced to the posture positioned on the extension surface of the wind flow runway formed in the air outlet, as a result, the runway is extended. As a result, the directivity of the wind flow can be improved and the flow can be stabilized.

According to the sixth aspect, the blade surface width of the wind direction louver is made longer than that of the flat wall surface formed downward from the opening end of the air outlet and having a small vertical width, and the air flow 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 can be in an enlarged form and can be efficiently blown downward or can be divided into a horizontal flow and a downward flow.

According to the seventh aspect, since the wing surface of the wind direction louver is movable between the position on the extension surface of the wind flow runway and the position overlapping with the flat wall surface, the air flow direction louver is diverted by the other wind direction louver. The lower wind flow can be easily changed.
