Description

[Detailed description of the invention] This invention relates to a wind direction changing device used in air conditioners, etc.
In particular, the wind direction changing body is designed to be able to be rotated smoothly while preventing the wind direction changing body from rotating naturally due to its own weight.

Conventionally, the air outlet 2 of the wall-mounted air conditioner 1 shown in FIG. 1 has shaft holes 3, 3 provided on both sides of the air outlet 2, as shown in detail in FIGS. 2 and 3, for example. bearing plates 5', 6 having
, 8 and whose center of gravity is located higher than the axis and is supported rotatably forward and downward; The airflow direction changing device includes a spring plate 10 fixed to the tip of the rotating shaft 7 so as to hold the airflow direction changing body 9 in any rotational position.

Incidentally, one shaft 7 of the wind direction changing body 9 is connected to the shaft 7 as shown in FIG.
The wind direction changing body 9 is supported so as not to move in the axial direction by the action of the surrounding spacer 11 and the spring plate 10, and the other shaft 8
is simply inserted into the shaft hole.

In the wind direction changing device having such a configuration, the center of gravity of the wind direction changing body 9 is located higher than the axis of the wind direction changing body.

Therefore, the more the wind direction changing body 9 is tilted forward and downward, the more the wind direction changing body 9 is likely to rotate forward and downward due to its own weight.

Furthermore, as the angle of inclination toward the front and lower sides of the wind direction changing body increases, the rotational force gradually increases, making it easier to rotate.

In contrast, in the past, the bearing plate 5' was simply pressed by the spring plate 10.

Therefore, if the pressing force of the spring plate 10 is weak, there is a risk that the wind direction changing body 9 will rotate from the state shown in FIG.

Therefore, in order to prevent rotation, the spring force of the spring plate 10 has to be increased, or a notch has been provided in the portion of the bearing plate 5' on which the free end of the spring plate 10 slides.

However, in the former method, there is a risk that the spring force of the spring plate 10 becomes too strong, which may interfere with the rotation of the wind direction changing body 9, and in the latter method, the rotation of the wind direction changing body 9 is gradual due to the bocce. It became.

As described above, both structures have the disadvantage that the wind direction changing body 9 cannot be smoothly tilted forward and downward.

The present invention was developed in view of this point, and the thickness of the portion of the bearing plate 5 where the spring plate 10 comes into sliding contact is gradually increased as the forward inclination angle of the wind direction deflector 9 increases. ,
In the embodiment shown in FIG. 4, the thickness of the bearing plate 5 is gradually increased to a dimension of 1-1+α over the entire area, but the thickness is increased only in the sliding contact portion of the spring plate 10. Also good.

That is, the center of gravity of the wind direction changing body 9 is located higher than the axis of the wind direction changing body, and the thickness of the portion of the bearing plate 5 that the spring plate 10 comes into contact with is gradually increased, so that the spring plate 10 is not pushed. By offsetting the pressure and the rotational force of the wind direction changing body 9, the wind direction changing body 9 can be rotated smoothly with a constant force while preventing the changing body from rotating naturally due to its own weight.

Therefore, according to the present invention, the wind direction changing body 9 can be smoothly rotated forward and downward as in the conventional case, and as the forward inclination angle of the wind direction changing plate 9 increases, the pressing force by the spring plate 10 becomes stronger. Therefore, the wind direction changing body 9 will not rotate freely due to slight vibrations etc. while the equipment is operating, and the forward and downward rotation of the wind direction changing body 9 can always be performed smoothly with a constant force. It has great practical value.

Note that the bearing plate 5,
6 is not limited to the structure shown in FIGS. 1 to 3.
