BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air flow rate adjusting device used in a ventilation passage of a duct of an air conditioner of a building or a building, a ventilation passage in an air conditioner and an industrial ventilation passage for blowing air. .

[0002]

2. Description of the Related Art A conventional air volume adjusting device arranges a damper or a plurality of blades in an air passage and rotates the damper / blades to change the passage area of the air passage to adjust the air volume. Further, the air volume adjustment in the middle of the air passage other than the air outlet is performed only a small number of times during installation, system change, etc.

[0003]

The conventional air volume adjusting device using dampers and blades has a drawback that the flow is disturbed by the dampers and blades, resulting in a large pressure loss. or,
There is a problem that there are many moving parts and the manufacturing cost is high. The problem to be solved by the present invention is to solve these conventional drawbacks, and to provide an air volume adjusting device which has a small pressure loss, a simple structure, and can be manufactured at low cost.

[0004]

Means for Solving the Problems The gist of the present invention which has solved the above problems is as follows: 1) A passage of an air chamber between an air inlet and an air outlet of an air chamber provided in the middle of the air passage. A curved flexible plate that has elasticity for partitioning the flexible plate is arranged, and an end portion of the flexible plate is provided at the ventilation port so that it can be detachably locked at a plurality of partition positions of the ventilation port. Required division of parts
An air volume adjusting device characterized in that an elastic closing plate for locking the end portion of the flexible plate at a position and closing one passage of the partitioned air chamber is attached to the flexible plate 2) Locking The member is in the air volume adjusting device according to the above 1), which is provided at each ventilation port of the air inflow port and the air outflow port.

[0005]

In the present invention, the flexible plate curved by elasticity is suspended between the air inlet and the air outlet of the air chamber,
The air passage of the air chamber is divided into two. Moreover, one of the divided air passages is closed by elastically pressing the free end of the closing plate attached to the flexible plate against the inner peripheral surface of the chamber, and the air passage in the air chamber is divided by the flexible plate. There is only a passage, and the ventilation area is narrowed, reducing the air volume. The mounting positions at the air inlet and the air outlet at the plate end of the flexible plate can be changed by changing a plurality of locking positions of the locking member, and the air volume is determined by the locking positions. . The mounting position of the plate end of the flexible plate with the locking member can be changed only on the air inlet side, only on the air outlet, or both depending on the purpose and the degree of restriction of the air flow direction. It can be decided as appropriate. The flexible plate is elastically deformed with a smooth curved surface according to the mounting position with the locking member. Since the flexible plate having a smooth curved surface forms the passage in the air chamber, air pressure loss and turbulence are small, and the wind direction can be changed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. The present embodiment is an example in which a flexible plate, a locking member, and a closing plate are provided in the air chamber that communicates the air outlet of the air blowing device of the air conditioning equipment with the duct for air volume adjustment and air direction adjustment. or,
In this embodiment, locking plates are provided on both the air inlet and the air outlet so that the positions of both ends can be adjusted.

FIG. 1 is a longitudinal sectional view of this embodiment, FIG. 2 is a side view of the same, and FIG. 3 is a perspective view showing a flexible plate of this embodiment. FIG.
Reference numerals 5 and 6 are explanatory views showing adjustment states of the air volume and the wind direction. In the figure, 1 is an air blowing device, 2 is an outlet cone, 3 is a duct, 4 is a rectangular parallelepiped air chamber provided in the ventilation path between the duct and the blowing cone 2, and 5 is an air flow in the air chamber 4. Entrance, 6
Is an air outlet, 7 is a flexible plate made of spring steel, 8 is a closing plate made of spring steel, 9 is a knob portion protruding from the tip of the flexible plate 7, 10 is a locking plate, and 11 is the same locking. It is an engaging groove of the plate.

In this embodiment, both ends of the flexible plate 7 are provided with a plurality of engaging grooves 1 of the locking plate 10 for the air inlet 5 and the air outlet 6.
The required engaging groove 11 of 1 is engaged. This engagement groove 1
The position of 1 determines the flow rate. Also, the air outlet 6
The engagement position on the side is selected at a required position mainly for adjusting the wind direction. In the state indicated by the solid line in FIG. 1, the flow rate is not restricted and air is sent to the air outlet 6 as it is. The state indicated by the solid line in FIG. 4 is an example in which the flow rate is throttled at the air inflow port 5 and uniformly sent from the air outflow port 6. 5 and 6 show a state in which the flow rate is reduced at the air inlet port 5 and air is sent downward or rightward from the right half of the hollow air outlet port 6 in the figure. In the present embodiment, the flow rate can be adjusted by selecting the engagement groove 11, and the air outflow location at the outflow port and its direction can be freely adjusted. Since the flexible plate smoothly curves in the air flow, the air flow is not disturbed, and the air flow can be performed in the required direction / position without pressure loss.

[0009]

As described above, according to the present invention, the flow rate can be freely adjusted by the above simple structure. Moreover, since the flexible plate is smoothly curved, the air flow can be made into a smooth air flow state with little turbulence, and the pressure loss is also small. Further, since the structure is simple, it can be manufactured at low cost.
