DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator structure having an improved ventilator case in an air conditioner.

[0002]

2. Description of the Related Art Conventionally, a ventilator (ventilator) for blowing air for air conditioning (hereinafter simply referred to as wind) is provided on both sides of an instrument panel in a vehicle compartment. This ventilator has an opening in the instrument panel,
As shown in FIG. 4, an opening 1a of the ventilator case 1 for blowing out the wind is exposed. The rear opening 1b of the ventilator case 1 is connected to a duct (not shown) of the air conditioner.

The structure of the ventilator case 1 will be described with reference to FIGS. 4 and 5 described above. Four horizontal fins 2 for controlling the vertical flow of the wind are provided on the opening 1a side in the ventilator case 1, and vertical fins 3 for controlling the horizontal flow of the wind are provided on the rear opening 1b side. Two are provided. In the figure, reference numeral 3a indicates a vertical fin on the left side of the ventilator case 1, and reference numeral 3b indicates a vertical fin on the right side of the ventilator case 1.

[0004] The horizontal fins 2 are rotatably mounted on a side wall 4 of the ventilator case 1 by a shaft 5, and these horizontal fins 2 are connected by a connector (not shown). The vertical fins 3 are rotatably mounted on upper and lower walls 6 by shafts 7 and are connected by connectors 8.

A knob 9 for changing the direction of the horizontal fin 2 and the vertical fin 3 is movably attached to the horizontal fin 2. Therefore, when the knob 9 is moved vertically, the horizontal fins 2 move, and when the knob 9 is moved horizontally, the vertical fins 3 move. By moving the knob 9 vertically and horizontally, both the horizontal fin 2 and the vertical fin 3 can be simultaneously moved vertically and horizontally.

As shown in FIG. 5, the ventilator case 1 has a substantial air blowing area.
When the vertical fin 3 inside is rotated from the top view, for example, by α degrees to the left, an extension line 10 of the left vertical fin 3a in the direction of the opening 1a of the ventilator case 1 and the ventilator case 1
Is determined by the distance L from the side wall 4 to the side wall 4. That is,
The greater the distance L, the greater the amount of change in wind direction (hereinafter referred to as wind direction).

Therefore, the distance L may be increased to improve the wind direction. There are two methods for increasing the distance L. One of them is to shorten the distance a between the shaft 7 of the vertical fin 3a and the opening 1a of the side wall 4. The other is vertical fin 3a
The distance b between the shaft 7 and the side wall 4 may be reduced.

A ventilator outlet is disclosed in Japanese Patent Publication No. 58-184438. In this publication, the side wall of the blowout cylinder on the side of the louver fin is widened from the tip of the louver fin or a position corresponding to the swing center to the tip of the blowout fin.

[0009]

In the prior art described above, in order to improve the wind direction of the ventilator case 1, the distance a between the shaft 7 of the vertical fin 3a and the opening 1a of the side wall 4 is required.
In this case, the distance c between the shaft 7 of the vertical fin 3a and the tip of the vertical fin 3a becomes short, and the distance between the side wall 4 and the tip of the vertical fin 3b on the right side is reduced. There is a problem that the amount of wind A passing through increases and the wind direction deteriorates.

When the distance b between the shaft 7 of the vertical fin 3a and the side wall 4 is reduced, that is, the vertical fin 3a
When the distance b is shortened by moving the shaft 7 of the vertical fin 3a, the distance e between the shaft 7 of the vertical fin 3a on the left side and the shaft 7 of the vertical fin 3b on the right side increases, or the shaft 7 of the vertical fin 3a And the distance d from the rear end of the vertical fin 3a becomes shorter, and as a result,
The wind B passing straight between the vertical fins 3a and the vertical fins 3b increases, and there is a problem that the wind direction deteriorates as described above.

Since the ventilator outlet disclosed in Japanese Patent Publication No. 58-184438 has a widened side wall of the outlet cylinder, it is necessary to change the surface shape of the instrument panel, which makes the operation complicated. Therefore, there is a problem that the workability is reduced, and the problem of the present invention has not been solved.
