Abstract

PURPOSE:To uniformize the speed of blow-off air throughout the whole area of the blow-off port by a method wherein the air inflow ends of respective smoothening vanes are aligned with the diagonal of a duct opening part. CONSTITUTION:The opening 3 of the air blow-off port is provided on the wall of a duct 1 and a plurality of the straightening vanes 2 are arranged perpendicular to a duct axis on the opening 3. The air inflow ends of the respective straightening vanes 2 are lain on the diagonal 4 of the opening part and at the same time their air blow-off ends are made flush with the plane of the opening 3. Furthermore, a straightening lattice 5 is arranged on the upstream side of the straightening vanes 2. Now, let (a) denotes the height of the duct, (b) the length of the opening part, and (c) the widths of both the duct and of an opening, then the area enlargement ratio or the ratio of the opening area to the cross-sectional area of the duct (e) becomes b/a and yet, because the air inflow ends of the straightening vanes 2 are aligned with the diagonal, the airs divided by the respective smoothening vanes 2 are uniformly reduced in their speed to 1/e of the speed just before flowing in the vanes 2 and then flowed out of the opening 3. In such a manner as mentioned above, air stream in the duct can be divided, decelerated, and turned in the direction of flow by 90 deg. by the smoothening vanes 2 in order to blow-off through the opening 3.

However, effective air blowing was not achieved.

本発明は、このような要望を実現したもので、以下に図

An air blowout CX+, characterized in that the air blowing end of each rectifying plate (2) is aligned with the plane of the opening (3), while U is aligned with the opening diagonal line (, 4). 2. The air outlet according to claim 1, wherein each rectifier plate (2) has a stepped neck at equal intervals. 3. Technical Field for Detailed Description of the Invention This invention relates to an air outlet. In cases where the area of the frontage of the air outlet is particularly large compared to the cross-sectional area, the air velocity of the air outlet is uniform over the entire surface of the opening. However, an effective air outlet has not been realized. Purpose This defense was made to solve the above-mentioned problem, and its purpose was to reduce the air velocity to the air outlet. []Open[]
It is located in a vine that provides an air outlet that can be uniformized over the entire surface of the air. EXAMPLE An example embodying the present invention will be described below with reference to the drawings. Figures 1 and 2 show a side cross section and a plane cross section of an air outlet 1, in which an opening 3 is provided in the wall of the duct h1, and a plurality of rectifying plates 2 are installed inside the duct 1 at a portion 113 between them. It is installed perpendicular to the axis. Each baffle plate 2 has its large airflow end aligned with the opening diagonal line 4 shown by the dashed line in FIG. 1, and its air outlet end aligned with the plane of the opening 3. 5 is a rectifier grid installed inside the ducts 1-1. In this way, Dak! The IC air flowing through the chamber passes through the rectifying grid 5 and enters the air inlet 9 of the rectifying plate 2.
At the same time as it is divided, it changes direction at right angles, flows along the rectifying plate 2, and flows out from the outlet end. If the width and the frontage width are the same and it is written as C, the value of the area expansion rate e, which is the ratio of the frontage area to the duct cross-sectional area, will be b/a. The air divided by each current plate 2 is uniformly decelerated to 1/e and flows out from the opening 3. In this way, the airflow inside the duct is controlled by the rectifying plate 2.
It is possible to divide the air into three parts, decelerate it, change the direction at right angles, and blow it out from the opening 3. The above explanation was confirmed by a flow test, and it was found that the greater the number of rectifying plates, the more uniform the air flow velocity at the opening 3.As can be seen from the above explanation, the present invention is an air outlet using a rectifying plate type that allows the air blowing speed to be uniform and the area expansion rate e to be large. The speed of the blown air becomes uniform ()11
is 1! In general, it is better to install 11 or more rectifying plates 2 with an interval of 1/'3 of the rough 1 to height 3 height d. In the Kinotsu example, the inside of the air 1 (output II fJ, ri') 1.
L/Ta, 2:C If the airflow is turbulent to 1・'j, C'v'% (exclude -ct) J, I,. Next, the second embodiment of this (j Ming) is shown in FIG.
Bright (Jru, 3 + i1' + record M) Example -C is the -C installed at the end of the air blower 11th -14-tough 1-1. As shown in the figure, there are 11 volumes in the middle of Tact 1.
9- Install a synchro and install an air outlet in its casing 6. This J, it is possible to install and cover (TL sa, q) several numbers...: (21 constriction blowout 1] 1) in the middle of Unizurepo Tough 1 and 1. Actual 7JI!!The leap is β (bright-4) according to Figs. This is an example of
I-side type blowout D
This can be easily achieved by covering the value of . However, the width of the outlet is 1-width, and the culm becomes smaller.
The velocity of the air flowing into the plane Suita [-] tends to be non-uniform, and therefore the velocity of the air flowing out from the Suita exit J tends to become non-uniform. In order to eliminate these drawbacks, η, j,
