[0006]

In the wind direction deflecting device for an air conditioner as described above, for example, when the air is blown downward in the direction of 60 ° during heating, the warm air reaches the floor and follows the floor. It is pushed forward and the warm air circulates well throughout the room, and a uniform temperature distribution provides a comfortable heating effect. However, on the other hand, since the hot air is blown downward as a jet at the total air volume, there are many uncomfortable areas due to the draft, and near the lower part of the outlet, hot air is directly generated, so that a part of the high temperature area is generated. There are drawbacks.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a wind direction deflecting device of an air conditioner which can form a more comfortable temperature distribution and can eliminate a sense of drafty caused by downward blowing. Things.

[0008]

In order to achieve the above object, the wind direction deflecting device of the air conditioner according to the present invention is configured such that the wind direction deflecting device descends toward the downstream side formed on the top plate on the upstream side of the outlet of the indoor unit main body. Inclined portion, a bias portion provided vertically projecting downward from the top plate on the outlet side of the inclined portion, and a horizontal guide plate having a horizontal surface formed on the downstream side of the bias portion, Below the horizontal guide plate, an upwardly convex substantially arc-shaped curved surface is formed, which is supported rotatably about an axis which is vertical and horizontal to the air flow and whose upper surface slopes steeply as it goes downstream. The fluid guide vane has a fluid guide blade that is inclined to the downstream side as the side surface on the upstream side goes downward, and a nozzle portion is formed by the curved surface of the fluid guide blade and the bias portion.

Further, a wind direction deflecting plate rotatably supported on an axis vertical and horizontal to the air flow at substantially the center in the vertical direction of the nozzle portion, and a downward direction below the inclined portion toward the downstream. A fluid guide wall that forms a generally arcuate curved surface that is convex upwardly with a steep slope, a downward opening formed by the upstream side surface of the fluid guide blade and the fluid guide wall, A guide plate rotatably supported about an axis perpendicular and horizontal to the air flow above the opening so as to open and close the opening.

[0010]

The wind direction deflecting device of the air conditioner according to the present invention is configured as described above. For example, in the case of blowing downward during heating, the downward opening is opened by rotating the guide plate, and the downward blowing is performed. The air volume ratio is set, a predetermined amount of warm air is blown out from the opening, the rotation of the wind direction deflecting plate and the fluid guide blade, the Coanda effect on the curved surface of the fluid guide blade, and the downward back pressure due to the bias unit. , And blows out from the nozzle at a predetermined blowing angle.

[0011] Therefore, the draft region can be reduced by blowing hot air from two places, and the hot air blown out from the front is blown downward at a predetermined angle, thereby eliminating a biased high-temperature region. Therefore, a uniform temperature distribution can be realized throughout the room.

Further, during cooling, by closing the downward opening by the guide plate, the cold air can be blown out more efficiently from the nozzle portion. By blowing the air at an angle or swinging the cool air, more efficient cooling can be realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a ceiling-suspended air conditioner provided with a wind direction deflecting device of an air conditioner according to one embodiment of the present invention. In FIG. 1, reference numeral 21 denotes an air conditioner main body. Inside the air conditioner main body 21, a blower chamber 24 having a sirocco fan 22 and a suction port 23, and a heat exchange chamber 2 having a heat exchanger 25 are provided.
6 and the blower chamber 24 and the heat exchange chamber 26
Is divided by

A drain pan 2 is provided below the heat exchanger 25.
8 are arranged. The top plate 29 is located downstream of the heat exchanger 25.
A heat insulating material 30 is stuck along the inner surface of the top plate 29, and a slope 31 is formed on the downstream side of the top plate 29, which is inclined downward toward the downstream side. And a horizontal guide plate 33 having a horizontal surface is provided downstream of the bias portion 32.

Below the horizontal guide plate 33, it is supported so as to be rotatable about an axis vertical and horizontal to the air flow, and its downward slope becomes steep as its upper surface goes downstream. The fluid guide vane 34 has a curved surface 34a, and the upstream side surface 34b is inclined downward toward the downstream side as it goes downward. The nozzle portion 35 is formed by the curved surface 34a of the fluid guide blade 34 and the bias portion 32.

At a substantially vertical center of the nozzle portion 35, a wind direction deflecting plate 36 is rotatable about an axis which is vertical and horizontal to the air flow.
I support. Below the inclined portion 31, a fluid guide wall 39 is provided which forms a generally arcuate curved surface that is upwardly convex and has a steep downward inclination toward the downstream side. And
The upstream side surface 34b of the fluid guide blade 34 and the fluid guide wall 39
Thus, a downward opening 37 is formed.

The inflow port 38 that flows into the nozzle section 36 is formed by the inclined section 31 and the opening section 37. Opening 37
And a guide plate 40 rotatably supported about an axis perpendicular to and horizontal to the air flow above the opening 37 so as to be able to open and close.

The operation of the wind direction deflecting device configured as described above will be described below.

First, as shown in FIG. 2, the guide plate 40 is rotated so that the downstream side thereof is inclined downward, and the downstream end of the guide plate 40 is positioned such that the downstream end of the guide plate 40 approaches the fluid guide wall 39. By doing so, the opening 37 is opened and the wind direction deflecting plate 36 is also rotated so that its downstream side is inclined downward, so that the downstream end of the wind direction deflecting plate 36 is positioned so as to approach the fluid guide blade 34. At the same time, the fluid guide vane 34 is rotated so that the downstream side of the curved surface 34a having a substantially circular arc is inclined downward.

As a result, the air flow C heat-exchanged by the heat exchanger 25 flows into the inlet 38, and the upper flow of the air flow C becomes the downward flow D by the inclined portion 31, and the flow D becomes the bias portion. 32 results in a flow E directed downward. The horizontal flow F is deflected downward by the flow E, and becomes a downward flow G along the wind direction deflecting plate 36.

The flow H below the wind direction deflecting plate 36 is deflected downward along the wind direction deflecting plate 36 and deflects downward by being attached to the curved surface 34a of the fluid guide vane 34 to be blown out. The flow H attracts the upper flow G and merges into a blowout jet I, which is blown downward and forward.
A part of the flow below the air flow C becomes a downward flow J by the guide plate 40 and flows downward along the curved surface of the fluid guide wall 39. Further, a part of the flow F becomes a flow K which is attracted by the flow J and flows into the opening 37, and becomes a jet L which merges with the flow J and is blown downward from the opening 37.

Next, in the case of horizontal blowing, as shown in FIG. 3, the guide plate 40 is rotated to close the opening 37, the fluid guide blade 34 is rotated so that the curved surface 34a faces upward, and the wind direction is changed. By rotating the downstream end of the deflecting plate 36 so as to be horizontal to the flow or slightly upward from the horizontal, the air flow C heat-exchanged by the heat exchanger 25 flows into the inlet 38, The flow above C is ramp 3
The flow D becomes a downward flow D, and the flow D becomes a downward flow E by the bias unit 32.

A part of the horizontal flow F goes straight as it is,
The flow E merges with the flow direction deflection plate 36 above and becomes a horizontal flow M due to the Coanda effect in the horizontal guide plate 33. The flow below the horizontal flow F becomes a flow N that travels straight between the fluid guide vanes 34 and the wind direction deflecting plate 36, is attracted by the flow M, and is blown out horizontally as a horizontal jet O. At this time, the guide plate 40 is rotated so as to be horizontal, and does not blow downward because the opening 37 is closed.

Further, the horizontal jet O is swung up and down by the rotation of the wind direction deflecting plate 36, and downward deflection can be arbitrarily performed.

[0026]

[Effect of the invention] As described above, the wind direction deflector of the invention is
An inclined portion formed on the top plate on the upstream side of the outlet of the indoor unit main body and inclined downward toward the downstream side, and a bias portion provided on the outlet side of the inclined portion so as to project vertically downward from the top plate. A horizontal guide plate having a horizontal surface formed on the downstream side of the bias unit; and a lower surface below the horizontal guide plate that is supported rotatably about an axis that is vertical and horizontal to the airflow and the upper surface is downstream. A fluid guide vane that forms a generally arcuate curved surface that is upwardly convex with a downward slope that becomes steeper as it goes toward, and that has an upstream side that slopes downstream as it goes downward. A nozzle portion is formed by the curved surface and the bias portion.

Further, a wind direction deflecting plate rotatably supported about a vertical axis and a horizontal axis with respect to the air flow at substantially the center in the vertical direction of the nozzle portion, and a downward direction as it goes downstream below the inclined portion. A fluid guide wall that forms a generally arcuate curved surface that is convex upwardly with a steep slope, a downward opening formed by the upstream side surface of the fluid guide blade and the fluid guide wall, A guide plate rotatably supported about an axis perpendicular and horizontal to the air flow above the opening so as to open and close the opening.

[0028] With this, warm air can be blown at a predetermined angle from the downward opening portion and the nozzle portion at the time of heating, so that the entire air volume does not blow down from one outlet, eliminating a sense of drafty. At the same time, a part of the high temperature distribution area below the indoor unit main body can be eliminated by the front blow-off flow, so that a more uniform temperature distribution can be achieved and comfort can be increased.

In addition, horizontal blowing at the time of cooling can be sufficiently ensured, and furthermore, a swing and an arbitrary blowing angle can be selected by the wind direction deflecting plate, so that more effective air conditioning becomes possible, which is extremely effective in practical use.
