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

[0002]

2. Description of the Related Art FIG. 5 shows an example of a conventional air-conditioning air outlet structure.
An air outlet member 52 is attached to the opening of the air outlet 1 and fins 54 for rectifying the air in the vertical direction are provided in the air outlet 53.
And fins 55 for performing rectification in the left-right direction are incorporated, 56 is a rectification knob in the vertical direction, 57 is a rectification dial in the left-right direction, and 58 is an air-conditioning duct opening / closing lever.

[0003]

As described above, in the conventional structure, even when the air conditioner is not used, the rectifying fins and the like are exposed, and the degree of freedom in design is low. In addition, since components such as fins are always exposed, dirt such as dust easily accumulates and cleaning is difficult. Further, the rectification in the vertical and horizontal directions is performed by fins, and the resistance of the outflow air is large, so that a sufficient blowout amount cannot be obtained. In addition, since the wind directions in the up, down, left, and right directions are adjusted by the fins, the blowing direction is limited.

Accordingly, an object of the present invention is to improve the appearance and the degree of freedom in design, to facilitate cleaning, to increase the degree of freedom in the direction of air discharge, to easily control the amount of blown air, and to further reduce the amount of air flowing out. It is an object of the present invention to provide a vehicle air-conditioning air outlet structure capable of reducing the resistance.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a structure of an air-conditioning air outlet provided in an opening formed in an interior part of a vehicle. An outlet cap having an air outlet in at least a part of its surroundings is installed so as to be able to protrude and retract and to be rotatable. Specifically, the outlet cap is capable of moving up and down in the vertical direction, and the air outlet is provided with fins for rectifying only in the vertical direction.

[0006]

First, since the outlet cap has an air outlet at the periphery and can be retracted, when not in use, the outlet cap is pushed into the opening to improve the appearance and the degree of freedom of design, and to clean. It will be easier. And because it is a rotatable outlet cap,
The degree of freedom is increased by setting the air discharge direction to all directions of 360 °, and the amount of blown air can be easily controlled by operating the outlet cap vertically. Further, the air outlet around the outlet cap only needs to be provided with fins for rectifying only in the vertical direction, so that the resistance of the outflow air is also reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, which shows an example of a use state of the air-conditioning outlet structure of the present invention, reference numeral 1 denotes an instrument panel as an interior part, and 11 denotes an outlet cap. On the upper surface of the instrument panel 1, as shown in FIGS. 2 and 3,
An opening 2 is formed, and an air conditioning duct 3 disposed inside the instrument panel 1 is connected to a cylindrical holder 4 attached to the opening 2.

The cylindrical holder 4 has a flange portion 5 overlapping the upper surface of the instrument panel 1.
The inner peripheral side of the upper surface is formed as a tapered surface 6. An outlet cap 11 is vertically movable in the cylindrical holder 4 as shown by an arrow B in FIG.
As shown in the figure, it is incorporated so as to be rotatable in the left-right direction.

The outlet cap 11 has a cylindrical portion 12.
And an upper wall portion 13 are integrally formed, and an air outlet 14 is formed around the cylindrical portion 12. A plurality of movable fins that perform straightening only in the vertical direction are formed in the air outlet 14. 15 are attached. Also, the upper wall 13
Has a curved upper surface and a flange 1
6, and the lower surface of the flange portion 16 is formed as a tapered surface 17.

A guide cylinder 8 is provided in the cylindrical holder 4.
The outlet cap 11 is fitted in the guide tube 8 by the cylindrical portion 12 so as to be slidable up and down and rotatable left and right. Further, as shown in FIG. 4, a plurality of spring storage recesses 7... 7 are formed in the circumferential direction above and below the inner periphery of the cylindrical holder 4, and correspond to the upper and lower sides of the guide cylinder 8. The ball storage holes 9 are formed.

There are provided balls 21... 21 that can protrude into the guide cylinder 8 from inside the upper and lower storage holes 9, 9. Are biased in the protruding direction by springs 22 provided in 7. On the other hand, an annular ball engaging groove 18 is formed in the lower part of the outer periphery of the cylindrical portion 12 of the outlet cap 11, and the balls 21 are engaged with the engaging groove 18 so that the outlet cap 11 shown in FIG. And the protruding state shown in FIG. 3 is maintained.

According to the air-conditioning outlet structure having the above configuration, the following advantages can be obtained as compared with the conventional structure. That is,
First, when not in use, as shown in FIG. 2, by immersing the outlet cap 11 in the instrument panel 1, the appearance is improved and the area around the instrument panel 1 is easily cleaned.

In use, FIGS. 1 and 3
As shown in the figure, the outlet cap 11 is projected on the instrument panel 1 so that the direction of the air outlet 14 of the cylindrical portion 12 can be changed to all directions of 360 °.
By changing the amount of protrusion of the cylindrical portion 12, the air outlet 1
4 can be changed. A movable fin 15 for rectifying only in the vertical direction is provided in the air outlet 14.
.. Need not be provided, and the resistance of the air flowing out from the air outlet 14 is low.

The outlet cap may be configured to be electrically operated by using an actuator such as a motor, or may be of a push-up type in which the outlet cap pops out when pushed by hand. In addition, a plurality of air outlets may be provided around the outlet cap, and the specific arrangement location, the detailed structure, the shape, and the like can be appropriately changed in addition to the embodiment.

[0015]

As described above, according to the air-conditioning outlet structure of the present invention, an outlet cap having an air outlet in at least a part of its periphery can be protruded into and retracted from the opening of the interior part. Because of this, it is possible to improve the appearance and design freedom when not in use, to make it easier to clean, to increase the degree of freedom in the air discharge direction, and to easily control the amount of blown air. be able to. Further, by merely providing fins for rectifying only in the vertical direction at the air outlet around the outlet cap, the resistance of the outflow air can be reduced.
