Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in side defroster nozzles.

As is well known, a side defroster nozzle is positioned on the side of an instrument panel and is used to blow air led from an air conditioner to a side window.

Since quick clearing performance is usually required over a large area, air must be guided and blown efficiently against the side windows.

For this reason, a plurality of air guide plates have conventionally been incorporated into the side defroster nozzle to regulate or adjust the vertical and horizontal (diagonal) directionality of the blowing air.

However, it is difficult to install a large number of air guide plates in a limited space, and the air guide plates are in the form of a plate with a thickness that is enough to damage the structure. Moreover, since the wind blowing in the straight direction along the side of the nozzle tends to be strong, the wind blowing in the diagonal direction is affected by this, and the wind cannot be blown diagonally enough. The reality is that there are still many areas to be improved in terms of efficient air blowing.

The present invention was developed focusing on the diagonal point, and although the vertical direction of the blown air is regulated by a baffle plate similar to the conventional one, the left and right direction (diagonal direction) is controlled by this baffle plate. This is intended to be regulated by a cover with a special structure, thereby achieving efficient air blowing.

Specifically, the present invention forms air guide plates between the left and right frames in multiple stages to regulate the vertical directionality of the blowing air, and partially blocks each gap between the air guide plates so that the air blows out. A cover unit that regulates the left-right directionality of the wind is provided close to either the left or right side of the frame, and the cover unit faces the blowing direction and has a shielding area that gradually decreases from the upper stage, and the back side of the joint with the wind guide plate. It is an object of the present invention to provide a side defroster nozzle in which an air pocket is provided in the side defroster nozzle.

The details will be explained below based on the illustrated embodiment.

In the figure, reference numerals 1, 2, and 3 denote air guide plates that regulate the vertical direction of the blowing air, which are formed between the multi-stage left and right frames 4 and 5. Between each air guide plate 1, 2, and 3, Gap for blowing day 6, 7, 8
, and are arranged sequentially in the blowing direction (arrow A).

9, 10゜11.12 is an integrated cover provided in combination with the above-mentioned baffle plates 1, 2, 3, and is designed to partially cover the gaps 6, 7, 8, and is designed to control the horizontal direction (diagonal) of the blowing air. The aim is to regulate the direction of

The cover body 9 covers the entire top surface, but the remaining cover unit 10 covers the gap 6, the cover unit 11 covers the gap 7, and the cover unit 12 covers the gap 8. , 11 and 12 gradually decrease the shielding area in the blowing direction (arrow A), and are provided closer to the left frame 5 of the left and right frames 4 and 5, and are arranged in the plane of FIG. End surfaces 14, 15 along the diagonal line 13 connecting points X and Y in the state,
16.

As a result, the gaps 6, 7° 8 for blowing air have a wide opening on the front side and a narrow opening on the opposite side in the blowing direction (arrow A).

Such integral covers 11 and 12 are provided with wind traps 17 and 18 on the back side of the joints with the air guide plates 2 and 3 (the fourth
In the planar state shown in FIG. 1, these wind traps 17 and 1B are positioned in a direction intersecting the blowing direction (arrow A).

Of the left and right frames 4 and 5, the frame 4 that is not provided with the integrated cover 10, 11 and 12 has an inclined surface 19 along the oblique direction of the blowing air, so that the air guide plate 2 , 3 joining line 2
0.21 is also along the diagonal direction.

Next, the function of the side defroster nozzle having such a configuration will be described. Air supplied from the air conditioner (not shown) through the duct 22 is first divided by the baffle plates 1, 2, and 3 as shown in FIG. It tries to blow out in the direction of arrow B in FIG.

Then, this air is blown out from the gaps 6, 7, and 8, but while the air is flowing straight toward the gaps 6, 7, and 8, the air that is flowing toward the covers 10, 11, and 12 is directed to the air guide plate. Wind trap portion 17, 1B provided on the back side of the joint with 2, 3,
That is, the air collides with the wind pockets 17 and 18 located in the direction crossing the direction of air travel, and the collided air flows into the gaps 6 and 7.
．． The flow direction is changed to 8 directions and interferes with the air that was traveling straight toward gaps 6 and 7.8.

As a result, the air blown out from the gaps 6, 7, and 8 is given directionality in the diagonal direction shown by arrow A in Figure 1, and is guided directly toward the side window (not shown). It is something.

The inclined surface 19 of the right frame body 4 also assists in the diagonal directionality of air.

As explained above, the side defroster according to the present invention
The nozzle uses a baffle plate to regulate the vertical direction of the blowing air, and the cover area is gradually reduced from the upper stage toward the blowing direction through the gap that serves as the blowing outlet, and the cover is integrated with each other toward either the left or right frame side. The airflow that collides with the back surface is guided toward the gap, and finally the air that blows out from the gap is given left-right (diagonal) directionality so that it blows out pointing in the direction of the side window, so it can be quickly Therefore, it is possible to expect a large area clearing performance, and extremely efficient air blowing becomes possible, so the practical benefits are enormous.
