Abstract

PURPOSE:To provide an outlet structure for an air conditioner which has small air flow resistance at the outlet, causes little air noise and in which fluctuations of a coupling position of a vertical blade to a coupling rod is small. CONSTITUTION:A crank-shaped shaft 25 of a vertical blade 22 disposed in a diffuser 21 is inserted into a tongue part 6. A coupling rod 26 is disposed in the part 6, the shaft 25 is coupled to the rod 26, and the blade 22 is rotated. Since the rod 26 is not provided in the outlet 21, air flow resistance in the outlet 21 is reduced, and air noise of the rod 26 is eliminated. Since the rod 26 is disposed in the part 6 and not exposed with cold air or warm air flowing in the outlet 21, thermal deformation of the coupling position of the rod 26 to the shaft 25 is reduced, it is not necessary to increase a clearance at the position, thereby decreasing fluctuations.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, there are air outlet structures for air conditioners as shown in FIGS. 3, 4, and 5 (for example, Japanese Utility Model Laid-Open No. 61-46316). As shown in FIG. 3, an air outlet 2 is provided on the front surface of the air conditioner 1, and the air outlet 2 is a sectional view and FIG. 4 which is an enlarged view of a portion A in FIG. As shown in FIG. 5, a plurality of vertical blades 3 are arranged. The vertical blades 3 are formed on the upper and lower sides of the blade body 4 by the shaft portions 5 and 6.
And the shaft portions 5 and 6 are supported by the drain pan 7 forming the upper surface of the air outlet 2 and the tongue portion 6 forming the lower surface of the air outlet 2. Further, the blade body 4 is provided with a notch 4a, a connecting rod 8 is arranged at the notch 4a, each blade body 4 is connected to the connecting rod 8 by a shaft 9, and a plurality of connecting rods 8 are provided. The blades 3 are tilted in the same direction at the same time. In addition, 10 is a rotor.

[0003]

However, in the air outlet structure of the conventional air conditioner described above, since the connecting rod 8 is arranged in the air outlet 2 through which the air flows, the air blowing resistance at the air outlet 2 is large. In addition, there is a problem that wind noise is generated by the connecting rod 8. Further, since cold air during cooling and hot air during heating pass through the outlet 2, thermal deformation of the connecting rod 8 and the shaft 9 is large, and correspondingly, a space between the connecting rod 8 and the shaft 9 is generated. And the clearance between the blade main body 4 and the shaft 9 must be increased, and there is a problem that rattling becomes large at the connecting portion between the connecting rod 8 and the vertical blade 3.

Therefore, an object of the present invention is to prevent the connecting rod from being arranged in the air outlet so as to reduce the ventilation resistance at the air outlet and prevent the wind noise from being generated by the connecting rod at the air outlet. Another object of the present invention is to provide an air outlet structure for an air conditioner that can reduce rattling at a connecting portion between a vertical blade and a connecting rod.

[0005]

In order to achieve the above object, the present invention is directed to an air conditioner in which a plurality of vertical blades are arranged at the air outlet, and the plurality of vertical blades are interlocked with each other by a connecting rod. In the air outlet structure, the shaft portion of the vertical blade is inserted into the tongue portion that constitutes the lower surface of the air outlet, and the connecting rod is disposed in the tongue portion, and the shaft portion in the tongue portion is connected to the connecting rod. It is characterized by being connected to each other by.

The shaft portion in the tongue portion has a crank shape, the crank-shaped shaft portion and the plate-shaped blade body of the vertical blade are on the same plane, and the connecting rod is It is desirable to rotatably connect to the tip of the crank-shaped shaft portion.

[0007]

When the connecting rod is operated, the shafts of the vertical blades are driven, and the vertical blades are tilted in the same direction.

At this time, since the connecting rod is in the tongue portion and not in the air outlet, it does not give a resistance to the wind passing through the air outlet, and therefore, the air blowing resistance is reduced. Further, since the connecting rod is not inside the outlet, no wind noise is generated by the connecting rod. Furthermore, since the connecting rod is inside the tongue and not at the outlet through which cold air or warm air passes, thermal deformation of the connecting rod is small, and therefore, the connecting point between the connecting rod and the shaft portion of the vertical blade is small. It is possible to reduce the clearance and eliminate rattling.

Further, the shaft portion in the tongue portion is formed into a crank shape, and the crank shaped shaft portion and the plate-like blade body of the vertical blade are on the same plane,
When the connecting rod is rotatably connected to the tip of the crank-shaped shaft portion, the tilt of the vertical blades can be easily adjusted and the structure can be simplified.

[0010]

The present invention will be described in detail below with reference to the embodiments shown in the drawings.

In FIG. 1, reference numeral 21 is an air conditioner air outlet, and 22 is a plurality of vertical blades arranged in the air outlet 21.

As shown in FIGS. 1 and 2, the vertical blade 22 is composed of a plate-shaped blade body 23 and upper and lower shaft portions 24 and 25. The upper shaft 24 is rotatably supported by the drain pan 7, while the lower shaft 25 is supported by the tongue 6 and is inserted into the tongue 6. That is, the lower shaft portion 25 has a crank shape, and most of the crank shape is inserted into the tongue portion 6. The crank-shaped shaft portion 25 and the plate-shaped blade body 23 are on the same plane. In this embodiment, when the vertical blades 22 are fully open, the shaft portion 25 is bent in the crank shape in the upstream direction of the air outlet 21, but is bent in the crank shape toward the downstream side of the air outlet 21. You may. On the other hand, a connecting rod 26 is arranged in the tongue portion 6, and the tips 25a of the shaft portions 25 of the plurality of vertical blades 23 are rotatably connected to the connecting rod 26. The shaft portion 25 is provided with a collar portion 29 that comes into contact with the tongue portion 6, and the shaft portion 25
Is supported on the tongue 6. In addition, 10 is a rotor.

According to the above construction, when the connecting rod 26 is driven in the direction orthogonal to the plane of the drawing in FIG. 2, the crank-shaped shaft portions 25 of the vertical blades 22 rotate, and the vertical blades 22 of these vertical blades 22 rotate. The blade body 23 tilts in the same direction.

At this time, the connecting rod 26 is in the tongue portion 6,
Since it is not inside the air outlet 21, the connecting rod 26 does not give resistance to the wind passing through the air outlet 21, thus reducing the air blowing resistance. Further, since the connecting rod 26 is not inside the outlet 21 and no wind flows around the connecting rod 26, no wind noise is generated by the connecting rod 26. Further, since the connecting rod 26 is inside the tongue portion 6 and is not in the outlet 21 through which cold air or warm air passes, thermal deformation of the connecting rod 26 is small, and therefore, the axes of the connecting rod 26 and the vertical blades 22 are small. The clearance between the tip 25a of the portion 25 can be reduced,
Therefore, rattling can be eliminated. Further, since the connecting rod 26 is connected to the shaft portion 25 of the vertical blade 23, it is not necessary to provide the notch 4a in the blade body 4 of the vertical blade 3 as in the conventional example shown in FIG.
The area of the blade body 23 is increased, and the direction control of the wind at the air outlet can be more effectively performed.

In the above embodiment, since the shaft portion 25 inserted in the tongue portion 6 has a crank shape, and the crank shape shaft portion 25 and the blade body 23 are on the same plane, the vertical blade is Adjustment of the tilt of 22 becomes easy, and
The structure is simple.

In the above embodiment, the shaft portion 25 of the vertical blade 22 inserted into the tongue portion 6 has a crank shape, but it may have a J shape, for example.

[0017]

As is apparent from the above, in the air outlet structure of the air conditioner of the present invention, the shaft portion of the vertical blade is inserted in the tongue portion, and the connecting rod is arranged in the tongue portion, and Since the part is rotated by the connecting rod,
Since there is no connecting rod in the blowout port, the blowing resistance at the blowout port can be reduced, and the wind noise due to the connecting rod does not occur. Further, since the connecting rod is inside the tongue and is not exposed to the cold air or the warm air flowing to the air outlet, the thermal deformation at the connecting portion between the connecting rod and the shaft portion is small, and therefore the clearance at the connecting portion is reduced. There is no need to increase the size, and rattling is reduced.
Furthermore, since it is not necessary to connect the blade body of the vertical blade to the connecting rod, the area of the blade body can be increased and therefore the wind direction can be effectively controlled.

Further, the shaft portion in the tongue portion is formed in a crank shape, and the crank shaped shaft portion and the plate-shaped blade body of the vertical blade are on the same plane,
When the connecting rod is rotatably connected to the tip of the crank-shaped shaft, the tilt of the vertical blades can be easily adjusted and the structure can be simplified.
