DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art A side view of the inside of an indoor unit of an air conditioner is, for example, as shown in FIG.
And a front cover 23 detachably mounted on the main body 22.
And a front panel 24 attached to the front cover 23 so as to be openable and closable. Upper part of housing 21 (front cover
A suction port 25 for taking in room air is provided in an upper portion of the front panel 23 and a front panel 24), and an air outlet 26 for sending heat-exchanged air into the room is formed in a lower portion of the front surface. An air filter 27, an indoor heat exchanger 29 bent back and forth, and a blower (cross flow fan) 30 are arranged in an air passage 27 connecting the suction port 25 and the air outlet 26. The air exchanged by the heat exchanger 29 is sent out to the outlet 26 by the blower 30, and the wind direction to the room is adjusted up and down and left and right by the upper and lower wind direction plates 31 and the left and right wind direction plates 32 provided in the blow outlet 26. For example, during the cooling operation, the upper and lower wind direction plates 31 are controlled in a substantially horizontal direction so as to reduce the descent of the cool air.
As shown in FIG. 3, the outlet 26 is directed downward by controlling the vertical direction to promote the descent of the warm air.

[0003]

However, when the vertical wind direction plate 31 rotates vertically as shown in FIG. 3, the flow of the wind becomes unnatural, so that turbulence is likely to occur near the air outlet 26 and noise is reduced. May be. In addition, A before and after the outlet 26
Therefore, it becomes difficult to operate the left and right wind direction boards 32 in an indoor unit in which the left and right wind direction boards 32 are of a manual type. Furthermore,
Even if the left and right wind direction plates 32 are adjusted obliquely, the wind passing through the left and right wind direction plates 32 is forcibly changed in the downward direction by the vertical wind direction plates 31, so that there is a problem that the wind does not proceed in the intended direction. Therefore, an object of the present invention is to provide an indoor unit of an air conditioner that solves these problems.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an air filter is provided in an air passage connecting an inlet at an upper portion of a housing and an outlet at a lower portion of the housing. And, an indoor heat exchanger, and a blower that sends out the air heat exchanged by the indoor heat exchanger to the outlet,
In a configuration in which the wind direction to the room is adjusted by upper and lower wind direction plates and left and right wind direction plates provided at the air outlet, the air outlet is provided with a movable diffuser in which a lower portion of the air outlet rotates forward. At the same time, the movable diffuser is provided with the left and right wind direction plates.

[0005]

According to the above construction, when the upper and lower wind direction plates are turned vertically during the heating operation, the movable diffuser is turned forward to widen the air outlet, thereby improving the flow of air. When the movable diffuser rotates forward, the left and right wind direction plates also rotate in the same direction and approach the outlet, so that the left and right wind direction plates can be easily operated, and the direction from which the wind from the outlet is intended Can be turned on.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing an appearance of an indoor unit. 1 is a main body 2, a front cover 3 detachably mounted on the main body 2, and a front panel 4 attached to the front cover 3 so as to be openable and closable. It is a housing consisting of: An air inlet 5 for indoor air is formed at an upper portion and a front portion of the housing 1, and an air outlet 6 is formed at a lower front portion. FIG. 2 is a side view of the inside of the center of the housing 1, and a removable air filter 8 is provided in an air passage 7 between the inlet 5 and the outlet 6.
An indoor heat exchanger 9 divided into a plurality of pieces and bent back and forth, and a blower (cross-flow fan) 10 for sending out the air heat-exchanged by the indoor heat exchanger 9 to the outlet 6 are arranged. The air outlet 6 is provided with a vertical wind direction plate 11 for adjusting the air blowing into the room up and down. In addition, a movable diffuser 13 that has a driving unit 12 at the lower part of the outlet 6 and that rotates the lower part of the outlet 6 forward is provided. The movable diffuser 13 adjusts the air blowing into the room to the left and right. Left and right wind direction board 14
Is installed.

By the way, the positions of the upper and lower wind louvers 11, the movable diffuser 13 and the left and right wind louvers 14 change according to the operation mode. For example, in the cooling operation, the upper and lower wind louvers 11 are rotated so as to be substantially horizontal. On the other hand, the movable diffuser 13 and the left and right wind direction plates 14 are held at positions indicated by broken lines. In such a state, the cool air from the outlet 6 can be sent far without lowering. Also,
In the heating operation, the upper and lower wind direction plates 11 are turned in a substantially vertical direction as shown to close the front of the air outlet 6, while the movable diffuser 13 and the left and right wind direction plates 14 are turned to the positions shown by solid lines to blow air. The space between the front and back of the outlet 6 is widened from A to B, and the left and right wind direction plates 14 are brought closer to the outlet 6, so that the flow of warm air into the room is improved. With such a configuration, turbulence near the air outlet 6 can be eliminated, and the operation of the left and right wind direction plates 14 can be simplified.

[0008]

As described above, if the indoor unit is as described above,
In the cooling operation, air can be blown as usual, and in the heating operation, the flow of air at the air outlet improves, so there is no risk of turbulence, and quieter operation is possible and the amount of air blown to the floor increases, making it comfortable. The performance is improved. Further, the operation of the left and right wind direction plates can be easily performed, which is convenient.
