Abstract

PURPOSE:To get a predetermined amount of air in an accurate manner even if an accuracy of fixing position of an amount of air distribution control vane is low in case of a severe eccentric flow at an upstream side of the outlet part by a method wherein a restricting plate is arranged at a further upstream side of the amount of air distributing control vane arranged at the upstream side of the outlet. CONSTITUTION:An amount of air distributing control vane 4 is arranged in a substantial horizontal direction within an outlet part 2. An air direction distribution control vane 3 for use in directing a flow of air toward a predetermined direction is connected at an extreme end of the air amount distribution control vane 4 toward a predetermined direction. A wedge-like restricting member 5 is arranged at a substantial perpendicular direction in a flow passage at an upstream end of the air amount distribution control vane 3. This restricting plate 5 has a wide base end and narrow at its top end and its base end corresponds to the part where a bent part shows a high air speed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air outlet member that can control air volume distribution and air direction distribution used in air conditioning systems, blowers, and the like.

[Conventional technology]

The air outlet members for controlling the air volume distribution and the wind direction distribution at the air outlet include air volume distribution control vanes 4 that determine the air volume based on the width of the flow path and air direction distribution control vanes that determine the wind direction based on the direction of the flow path as shown in FIG. There is one equipped with 3 vanes.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, when used to obtain a substantially uniform air volume in a portion of the air outlet upstream where there is severe drift due to the bent portion 10 of the duct 9 as shown in FIG. There was a problem in that the interval between the vanes 4 for distribution control had to be made very small, and the positioning error had a large effect on the air volume distribution error, making the positioning accuracy of the air volume distribution control vane 4 very strict. .

It is an object of the present invention to provide an air outlet member that can accurately obtain a predetermined air volume distribution even if the accuracy of the mounting position of the air volume distribution control vane is low when there is severe drifting upstream of the air outlet as described above. The purpose is

[Means to solve the problem]

The gist of the present invention is to provide an air outlet member in which a wind direction distribution control vane is provided at the air outlet portion and an air volume distribution control vane is provided upstream thereof, and a resistance plate is provided further upstream of the air volume distribution control vane. This is an air outlet member characterized by the following.

[For production]

In the outlet member configured as described above, the air volume can also be controlled by the resistance plate where the upstream speed of the air volume distribution control vane is high, so that a desired air volume distribution can be obtained at the outlet part.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the blower outlet member according to the present invention will be described based on an illustrative embodiment.

What is shown in FIG. 1 is an example of an air outlet member that constitutes the tip of the bent portion 10 of the duct 9. As shown in FIG.

Inside the outlet section 2, an air volume distribution control vane 4 is arranged approximately in parallel, and a wind direction distribution control member 73 is connected to the tip of the air volume distribution control vane 4 to direct the air flow in a desired direction. has been done.

A draft-shaped resistor 5 is arranged at the upstream end of the air volume distribution control vane 3 in a direction substantially perpendicular to the flow path. This resistance plate 5 is
The base is wide and becomes narrow toward the top, and the base corresponds to the portion of the bend 10 where the wind speed is high. Therefore, from the portion where the wind speed is large at the bend 10,
The amount of airflow that enters the airflow distribution control vane 4 via the resistance plate 5 is small, and from the portion where the wind speed is low inside from the bending portion 10,
The amount of airflow that enters the airflow distribution control vane 4 via the resistance plate 5 is large, and as a result, the amount of airflow flowing between each airflow distribution control vane 4 is approximately equal, and is flowed in the desired direction by the wind direction distribution control vane 3. The stars of the airflow are approximately equal in each direction.

Thus, the amount of airflow entering the airflow control vane 4 can be easily distributed to the same amount or to a required amount by appropriately adopting the wedge shape of the resistance plate 5.

Shown in FIG. 2 is a different embodiment of the invention.

This example has the same basic configuration as the example shown in FIG. 1, but differs in that the resistance plate 5 is formed by cutting and bending the upstream end of the air volume distribution control vane 4. That is, the bent part 10 side is cut wide and bent to be perpendicular to the flow path, and the reverse bent part 10 side is cut to a narrow width and bent to be perpendicular to the flow path. It is assumed that the same effect as the embodiment shown is achieved.

What is shown in FIG. 3 is the resistance plate 5 in the embodiment of FIG.
This is an example in which the tube is installed at an angle to the flow path.

By attaching the resistance plate 5 at an angle, the change in the wedge shape from the base to the top is made smoother, and the flow rate change from the bending part 10 to the opposite bending part side is made even smoother.

FIG. 4 shows yet another embodiment of the invention.

This example also has the same basic configuration as the example shown in FIG. This is an example that achieves the same effect as the embodiment shown in the figure.

〔Effect of the invention〕

Since the present invention is configured as described above, even when there is severe drifting upstream of the outlet, the positional accuracy of the air volume distribution control vane is low due to the functions of both the air volume control vane and the resistance plate. (However, it is possible to accurately obtain a predetermined air volume distribution at the outlet portion.
