Abstract

PURPOSE:To prevent blown off wind from receiving influences from the side wall of a blow-off cylinder and to positively advance the wind the direction of which has been adjusted, in a desired direction from louver fins. CONSTITUTION:The blow-off cylinder 1 is formed separately from a duct cylinder 4, and louver fins 2, 2,... for adjusting vertically is provided in the vicinity of the tip and surface 11 of the blow-off cylinder 1. On the side walls 12 and 12 of the blow-off cylinder 1 located at the sides of louver fins 3, 3,..., corner parts 13 are formed at positions corresponding to tip ends 32 of louver fins 3, 3, ... or the center shaft 31 of swinging movement, and the width from the corner parts to their tip ends 11 is enlarged. When the louver fins 3, 3,... are swung for adjusting the wind direction, wind passing between the louver fin 3 at the left end in the drawing and the side wall 12 directly advances in the desired direction because the wind near to the louver fins 3 does not hit the side wall 12 in the vicinity of the tip end 11 and hence does not move back because of its width has been enlarged.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilator outlet, and the direction of the outlet air can be effectively adjusted.

An example of a conventional ventilator outlet is shown in FIGS. 1 to 5.

That is, a vertical adjustment louver fin +2+, t2), etc., which can swing around a swing axis near the tip, is provided close to the 00 side of the tip of the blow-off tube (1), and the inside At the tip of the blow-off tube (1) (at a position recessed from 1υ), louver fins (3), 13 for left and right adjustment, which can swing around a swing axis in the center thereof, are arranged. .

However, in such a conventional ventilator outlet, as shown in FIG.
,... are not easily affected by the side wall of the blowout tube (1), whereas the left and right adjusting louver fins t3), ta),...
- is provided in a position recessed from the tip (11) of the blow-off tube (1), so as shown in FIG. 4, the louver fin (3).

When trying to adjust the wind direction by rotating (3),..., the air passage is constricted between the louver fin (3) on the left end in the figure and the pipe wall, increasing the flow velocity and causing the flow to flow along the pipe wall. Since the wind travels in a straight line, there is a problem in that not only can the direction of the wind not be changed in this part, but also that the velocity of the flow adversely affects the wind direction in other parts, making it impossible to effectively adjust the wind direction.

The present invention has been made by focusing on such conventional problems, and when a louver fin for adjusting the wind direction is provided at a position recessed from the tip of the blow-out tube, the tip of the blow-out tube is removed from the vicinity of the louver fin. The purpose of this invention is to widen the side wall of the blow-out tube so that the side wall of the blow-off tube does not have an adverse effect, thereby solving the above-mentioned problem.

The gist of the present invention to achieve such an object is to provide a ventilator outlet in which a louver fin is swingably provided in a position recessed from the tip of the outlet tube in the outlet tube. The ventilator outlet is characterized in that the side wall of the outlet tube on the side of the fin is widened from a position corresponding to the tip of the louver fin or the center of swing to the tip of the outlet tube.

The present invention will be further described below based on the illustrated embodiments.

Note that the same parts as in the conventional example are given the same reference numerals.

FIGS. 6 to 8 show an embodiment of the present invention, in which the blowout pipe (1) is formed separately from the duct pipe (4), and a louver fin for vertical adjustment is located close to the round surface of the tip thereof. t2) J2

In other words, as shown in Fig. 7, part of the corner (1 block,
It is within the position range corresponding to the distance (A1) between the swing center axis c31) of the louver fin (3) and the tip c, and the distance in the depth direction between the corner part 0:1 and the tip (c) distance(
A2) is desirably larger than the tip of the louver fin (3) at the rotated position (the three moving amounts (A3) shown by the dashed line).

The blow-off tube (1) has a stepped portion I formed by widening the receiving portion (4υ) of the duct tube (4) through a packing old.
is positioned and held.

According to the ventilator outlet having the above configuration, as shown in FIG. ,, Louver Fin (3) Thank you...
When the louver fin (3) at the left end in the figure is swung to adjust the wind direction, the wind passing between the louver fin (3) and the side wall (1) will pass between the louver fin (3) and the side wall (1). Therefore, the side wall a'! is near the tip (11).
Since it will not hit J and be returned, it will go straight to the desired wind direction, and the wind from side wall Q2+ will try to go around the corner behind α9, so the wind direction will also be pulled by it and bend in the desired direction. It will be done. Further, as shown in FIG. 8, since the tip (34) of the swung louver fin (3) is located further back from the corner (131), the amount of aperture is reduced, and therefore the increase in wind speed is also reduced.

According to the ventilator outlet according to the present invention, by widening the vicinity of the tip of the outlet tube, the outlet air is made less susceptible to the influence of the side wall of the outlet tube, so that the direction-adjusted wind is directly directed from the louver fins to the desired direction. steadily progressing in the direction of
Desired wind direction can be adjusted. Additionally, in the past, it was necessary to place the louver fin for adjusting the wind direction, which was more necessary, at the front, but since the wind direction adjustment function is almost the same regardless of whether it is placed at the front or the front, such consideration is no longer necessary. This increases the degree of freedom in design and is also advantageous in terms of design because the direction of the louver fins is not restricted.
