DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the embodiments of the present invention shown in FIGS. 1
Is an indoor unit body of the air conditioner, 2 is a front cover 3 detachably mounted on the front surface of the indoor unit body 1 and a suction port provided on the upper surface of the indoor unit body 1, and 4 is a suction port 2 A heat exchanger provided in an air passage connecting the
Is a blower fan that sends out the air exchanged by the heat exchanger 4 to an outlet described later, 6 is an outlet that blows out the heat-exchanged air, and 7 is a rotatable shaft 8 on the outlet 6. The left and right wind direction plates 9 supported by the shaft are upper and lower wind direction plates rotatably supported in front of the left and right wind direction plates 7. Reference numeral 10 denotes a box-shaped blowout unit provided at the blowout port 6. The blowout unit 10 protrudes forward and downward of the indoor unit main body 1, and covers the upper opening 11 of the front protrusion so as to be openable and closable. Exit 6
The first damper 12 supported by the support shaft 13 at the upper end of
A second damper 15 is provided at the lower end of the outlet 6 so as to open and close the back opening 14 of the lower protruding portion, and is supported at the lower end of the outlet port 6. A sliding plate 19 is formed by forming a blowing opening formed by the juxtaposed opening holes 17 and slidably contacting the inner surface of the blowing opening and forming opening holes 18 juxtaposed at substantially equal intervals. A heat insulating material 20 is attached to the inside of the joint between the opening holes 18, the inner surface of the first damper 12, and the inner surface of the second damper 15, and the upper opening 11 is provided. And a filter 21 in the back opening 14.
Is provided.

Next, the operation and effect of the above configuration will be described. First, the operation and effect at the time of cooling shown in FIG. 1 will be described. The upper and lower wind direction plates 9 are rotated to be horizontal, and the first damper 12 and the second damper 15 are rotated.
Are rotated horizontally so that the upper opening 11 is closed by the first damper 12 and the sliding plate 19 is slid to open the front opening 17 and open the lower opening 17. Close. By setting as described above, the blowing wind a1 blown out from the blowing outlet 6 is guided in the horizontal direction by the vertical wind direction plate 9, the first damper 12, and the second damper 15, and Is blown into the room as horizontal wind from the opening hole 17 of the vehicle. At this time, since the rear opening 14 is open, the air below the indoor unit 1 passes through the filter 21 from the rear opening 14 and is induced as the induced air b1 by the attraction of the blowing air a1. The blown air a1 and the induced wind b1 are mixed into the unit 10 and blown out from the opening 17 on the front surface. Since the relatively high-temperature air below the indoor unit 1 is mixed with the blown wind a1, the blown wind a1 becomes a blown wind having a relative humidity lower than the indoor temperature, so that it is a gentle wind with less discomfort even when it directly hits the body. And at a distance, the room temperature distribution can be improved.

Further, the sliding plate 19 is provided in the blowout opening.
By closing the opening 17 on the lower surface, it is possible to prevent the blow-out air a1 blown out from the opening 17 on the front surface from being sucked in as a shortcut. Further, the heat insulating material 20 is adhered to the inner surface of the first damper 12, the inner surface of the second damper 15, and the inside of the support portion between the opening holes 18 of the sliding plate 19, Since the cold blowing air from the outlet 6 is blocked by the heat insulating material 20, the blowing unit 10
And the first damper 12 and the second damper 15 can be prevented from being exposed to dew. It should be noted that instead of attaching the heat insulating material 20, instead of attaching the heat insulating material 20, the inside of the joint between the inside of the first damper 12, the inside of the second damper 15, and the opening 18 and the joint between the opening 17 and the joint. The same effect can be obtained even if a cavity is formed by hollow molding with the inside of the device. In addition, the induced wind b1 removes suspended matter in the room by the filter 21.

Next, the operation and effect during heating shown in FIG. 2 will be described. The first and second dampers 12 and 15 are turned so as to be perpendicular to each other, and the rear opening 14 is closed by the second damper 15. By sliding the sliding plate 19, the front opening 17 is closed and the lower opening 17 is opened. By setting as described above, the blown wind a1 blown out from the blowout port 6 is guided downward by the vertical wind direction plate 9, the first damper 12, and the second damper 15, and the lower surface of the lower surface is blown. The air is blown into the room as downward wind from the opening 17. At this time, since the upper surface opening 11 is open, the air above the room through the filter 21 from the upper surface opening 11 as the induced air b1 is generated as the induced air b1 by the attraction of the blown air a1. The blown wind a1 and the induced wind b1 are mixed and blown out from the opening 17 on the lower surface. Since the relatively high temperature air in the upper part of the room is taken into the blowing unit 10 and mixed and blown out, the air in the upper part of the room is easily stirred and the indoor temperature distribution can be improved.

Next, the operation and effect at the time of oblique blowing shown in FIG. 3 will be described. By rotating the vertical wind direction plate 9 obliquely downward, rotating the first damper 12 and the second damper 15 obliquely downward, and sliding the sliding plate 19 The opening 17 on the front surface and the opening 17 on the lower surface are opened. By setting as described above, the blowout air a1 blown out from the blowout port 6
Is guided obliquely downward by the vertical wind direction plate 9, the first damper 12, and the second damper 15, and is blown into the room as wind obliquely downward from the opening 17 on the front surface and the opening 17 on the lower surface. Is done. At this time, since the upper surface opening 11 and the rear opening 14 are open, the attraction of the blowing wind a1 causes the filter 21 to pass through the filter 21 from the upper surface opening 11 and the rear opening 14. The upper air in the room and the lower air are taken into the blowing unit 10 as the induced wind, and the blown air a1 and the induced wind are mixed to form the opening 17 on the front surface and the opening 17 on the lower surface. More blown out. Since the upper air and the lower air in the room are taken into the blowing unit 10 and mixed and blown out, the air in the whole room is easily stirred regardless of cooling or heating, and the room temperature distribution is improved. Can be.

Next, the case of blowing out in the same manner as in the prior art shown in FIG. 4 will be described. The first damper 12 is turned to be horizontal, the second damper 15 is turned to be vertical, and the sliding plate 19 is slid. The opening 17 on the lower surface is opened.
By setting as described above, the suction unit 1
0 does not work, and the blown wind blown out from the blowout port 6 can be blown out by changing the upper and lower wind direction in accordance with the direction of the upper and lower wind direction plates 9, which is the same as the conventional blowout. .

[0017]

As described above, according to the present invention,
By mixing the blown air and the room air, the blown air is less likely to be uncomfortable, and the air conditioner has an improved indoor temperature distribution.
