Reference numeral 8 denotes an arm, and several wind direction changing plates 5 are connected at one end of each wind direction changing plate 5 to form a set.

Reference numeral 9 denotes a lever provided on a portion of the arm 8, which is inserted into a slit-shaped window 10 provided at the left and right center portions of the louver frame 4, and protrudes toward the front side to the extent that it can be pinched by hand.

The conventional louver is constructed as described above, and in order to adjust the wind direction of the air conditioner, the arm 8 is moved by operating the lever 9, and the wind direction changing plate 5 connected to this arm 8 is rotated. . Wind direction change plate 5
The operating range of the lever 8 is determined by the size of the slit-shaped window 10, that is, the rotation angle of the wind direction changing plate 5 is determined.

[Problem that the invention attempts to solve]

Because the louvers of conventional air conditioners are constructed as described above, they are located almost in the center of the ventilation passage of the air outlet, which increases ventilation resistance; the direction of the air blown out is set to either up or down depending on whether it is hot air (heating) or cold air (cooling), but since the air conditioner main unit is generally installed in a high place inside the room, such as a window frame, it is necessary to set the air direction so that the space occupied by people is most comfortable; and furthermore, a slit-shaped window is formed to restrict the operating range of the lever, which also results in a configuration that blocks the ventilation passage, etc.

This idea was made to solve the above problems, and the arm is located at the rear of the lever frame so that it does not obstruct ventilation.
Moreover, the purpose is to be able to regulate the maximum change angle of the wind direction.

[Means for solving problems]

In the air conditioner louver according to this invention, the arm is positioned substantially on the same plane as the louver frame, the uneven portions and protrusions provided on the arm and the louver frame are opposed to each other, and the wind direction changing plate is A pair of protrusions are provided at positions that regulate the upward angle to be smaller than the downward angle, thereby regulating the maximum change angle of the wind direction.

[Effect]

The louver of the air conditioner in this invention has the louver frame and the arm located on substantially the same plane, so that ventilation is not obstructed, and the arm and the louver frame have recesses and protrusions mutually. to regulate the upward and downward angles of the wind direction changing plate.

〔Example〕

An embodiment of this invention will be described below with reference to FIG. 4. Reference numeral 1 denotes the air conditioner main body, 2 an indoor air inlet provided on the front of the main body 1, and 3 an outlet.
Reference numeral 4 denotes a louver frame body, and both ends of the longitudinal direction are integrally provided with rotating shafts 4a, 4a, and the longitudinal frame portion has a longitudinal crosspiece 4c and a plurality of reinforcing crosspieces 4d orthogonal to the crosspiece 4c. The right and left frames 4e, 4e are provided with reinforcing bars 4d and shaft holes 7 arranged almost linearly in the direction of the reinforcing bars 4d. There is. Reference numeral 5 designates a wind direction changing plate, which has a rotating shaft 6 on both front end surfaces, and is rotatably supported in the shaft hole 7 of the louver frame 4, and one rotating shaft 6 and A connecting shaft 5a is formed to protrude from the rear end surface of the rotating shaft 6 in the same direction. Reference numeral 8 denotes a flat plate-like arm body with a pair of upper and lower arms, the rear edge of which is formed linearly, and a substantially trapezoidal convex portion 8c in the center of the front end, which is continuous at the upper and lower positions of the convex portion 8c. Trapezoidal concave portion 8b
, a narrow surface 8d and a wide surface 8e are continuously formed as a whole, and the space is equally spaced by the number of wind direction changing plates 5 so that the connecting shaft 5a of the wind direction changing plate 5 is fitted in the center of the narrow surface 8d. Connecting hole 8 in a straight line.
A is arranged. Further, the arm body 8 is configured to fit the connecting shaft 5a of the wind direction changing plate 5 so as to be operatively connected, and to be positioned substantially on the same plane as the louver frame 4. Reference numeral 4b denotes a pair of substantially trapezoidal protrusions projecting from the rear end of the left frame 4e of the louver frame 4, which engage the end faces of the concave portion 8b and convex portion 8c formed at the front end of the arm 8, respectively. At the same time, when the arm 8 is in a sliding state and the angle of the wind direction changing plate 5 is set to β<α, the left frame protrusion 4b and the arm convex portion 8c are moved to each other when the wind direction changing plate 5 is oriented upward at an angle β during cooling operation. The collision position is at a downward angle α of the wind direction change plate 5 during heating operation.
At this time, the left frame projecting piece 4b and the arm concave portion 8b are formed at a position where they collide with each other. Reference numeral 11 denotes a knob provided on one of the plurality of wind direction changing plates 5 connected by the arm 8, and the louver frame 4
It is formed so that it protrudes from the front side to the extent that it can be pinched with your fingers.

Next, the operation of the lever in this embodiment formed in this way will be explained.

The louver frame 4 rotates around the longitudinal direction by shafts 4a provided at the upper and lower ends of the longitudinal direction, and by tilting the louver frame 4 at an arbitrary angle, the direction of the air blowing out from the air outlet 3 is adjusted to the direction of the louver frame. The air is blown in the direction of inclination of the body 4. Furthermore, by operating the knob 11 and rotating the wind direction changing plate 5 about the shaft 6, each of the wind direction changing plates 5 connected by the arm body 8 can be rotated.
are all tilted in the same direction, and the direction of the air blown out from the air outlet 3 can be set to the direction in which the wind direction change plate 5 is tilted, and when hot air is blown out during heating, the hot air flows across the floor. To do this, the direction of the wind direction change plate 5 is set to be greatly downward in order to blow the air downward as much as possible.On the other hand, it is better to blow the cold air in the front direction or slightly upward during cooling. The angle needs to be smaller than the downward angle of the warm air, and if the louver frame 4 is installed vertically in the longitudinal direction, the vertical movable range of the knob 11 is restricted by these conditions, so the knob When the protruding piece 4b of the louver frame 4 and the concave part 8b of the arm body 8 engage with each other when the part 11 is facing downward, the downward angle is limited to the limit when the change plate angle is α. When the knob part 11 is turned upward, the protruding piece 4b of the louver frame 4 collides with the convex part 8c of the arm body 8, and when the change plate angle is β, the upward angle is limited.

Further, in the above embodiment, the projecting piece 4b is provided on a part of the louver frame 4 side, and the concave portion 8b and convex portion 8c are provided on the arm side, but the same result will be obtained even if the concave and convex portions are reversed. .

[Effect of idea]

As described above, according to this invention, the arm is positioned substantially on the same plane as the louver frame, and the arm and the louver frame are provided with uneven parts and protrusions at the opposing ends, respectively, and the louver frame Since a pair of body side protrusions are provided at positions that restrict the upward angle of the wind direction change plate to be smaller than the downward angle,
It is possible to easily and reliably regulate the upward angle of the wind direction change plate used during cooling operation and the downward angle of the wind direction change plate used during heating operation, and also to control the airflow to the arm. This has practical effects such as eliminating noise caused by collisions.
