Abstract

PROBLEM TO BE SOLVED: To supply air up to all the corners of a room utilizing the difference of air velocity between the upper and lower parts of an air outlet efficiently. SOLUTION: The air conditioner comprises an air inlet 2 provided on one side in the front surface of the air conditioner body 1, a heat exchanger 5 disposed in an air passage 4 leading to an air outlet 3 provided at an upper part on the other side in order to exchange heat with air sucked from the air inlet, a fan casing 6 for sucking conditioned air passed through the heat exchanger from the front face 6a and leading it to a supply air duct 4' on the back of the air outlet at the upper part 6b in the side face, a centrifugal fan 6' contained in the fan casing, and a movable left/right wind deflecting plate 7 having a plurality of deflecting plates Va for deflecting conditioned supply air to the left and right. Since the left/right deflecting plate is partitioned vertically into a plurality of sections and ventilation resistance of the upper left/right deflecting plate is set higher than that of the lower wind deflecting plate, velocity of air being supplied from the upper part of the air outlet is increased furthermore and the air is supplied to a farther place. When the left/right deflecting plate is turned to the left/right, air can be supplied up to all the corners of a room.

BEST MODE FOR CARRYING OUT THE INVENTION An air conditioner according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a three-view drawing showing an embodiment of an air conditioner according to the present invention. As shown in the figure, the air conditioner body 1 has a suction port 2 on one side of the front surface and a blowout port 3 on the upper side of the other side. A heat exchanger 5 arranged in the air passage 4 connecting the suction port 2 and the blowout port 3 so as to face the back surface of the suction port 2 and exchanging heat with the air sucked from the suction port 2. The conditioned air, which is arranged on the back surface of the heat exchanger 5 and which has passed through the heat exchanger 5, has a front suction port 6a.
A fan casing 6 that draws in air from the upper side outlet 6b and guides the air to the outlet air passage 4'on the rear side of the outlet 3;
Centrifugal fan 6 ′ housed in the fan casing 6
And a rotatable left and right wind direction plate which is formed of a plurality of deflection plates 7a and is provided at the air outlet 3 and which deflects the air blown from the centrifugal fan 6'through the air outlet 4'to the left or right. 7 are provided. As shown in FIG. 1, the left and right wind direction plates 7 are provided with an upper frame 71 with a long depth and a lower frame 72 with a short depth which are vertically connected, and three deflection plates 7a with the depth aligned with the upper frame 71. The lower frame 72 is provided with two deflection plates 7a having a matched depth. A rotary shaft 7j is provided on the upper surface of the upper frame 71 and the lower surface of the lower frame 72 on a vertical line passing through the center of gravity of the left and right airflow direction plates 7 and is rotatably driven by a motor (not shown) so as to be rotatable. Is attached to. Reference numeral 10 is a control unit for accommodating a drive unit such as a motor (not shown) and a control board.

In the above structure, the operation during the cooling operation will be described next. The room air sucked through the suction port 2 exchanges heat with the heat exchanger 5 and is cooled. The cooled conditioned air is blown to the outlet 3 by the centrifugal fan 6'through the blowout air passage 4 ', and is deflected to the left and right by the left and right wind direction plates 7. At this time, since the centrifugal fan 6 ′ blows air by centrifugal force, the wind speed above the air outlet 3 corresponding to the outside of the centrifugal fan 6 ′ becomes faster, and in comparison with this, the centrifugal fan 6 ′ is.
The wind speed below the air outlet 3 corresponding to the center of is low. Since the conditioned air blown from above the blowout port 3 passes through the three deflecting plates 7a, the wind speed is further accelerated to be blown away, and the conditioned air blown from below the blowout port 3 is Since the two deflecting plates 7a are ventilated, the wind speed is reduced and air is blown nearby, so that it is possible to blow air to every corner of the room as shown in FIG. 1 (b).

[0013]

As described above, according to the air conditioner of the present invention, the suction port is provided in the air passage that connects the suction port provided on one side of the front surface of the air conditioner body and the air outlet provided on the upper side of the other side. A heat exchanger that is arranged opposite to the mouth and exchanges heat with the air sucked from the suction port, and the conditioned air that is arranged on the back surface of the heat exchanger and that has passed through the heat exchanger sucks from the front surface. And a fan casing that guides air to the blowout air passage on the backside of the blowout port on the upper side of the side face, a centrifugal fan housed in the fan casing, and a plurality of deflection plates disposed at the blowout port, In an air conditioner provided with a rotatable left and right wind direction plate that deflects the conditioned air blown through the air passage to the left and right, the left and right wind direction plates are divided into a plurality of upper and lower parts,
Since the upper left and right wind direction plates have greater ventilation resistance than the lower part, the wind speed of the blown air from the upper side of the outlet where the wind speed is originally high is further increased, which allows conditioned air to reach further and the left and right wind direction plates to the left and right. It is possible to provide an air conditioner that can blow air to every corner of the room by rotating the air conditioner.
