Description

[Detailed explanation of the idea] This invention relates to improvement of air conditioning vents.

In recent years, other equipment such as lighting equipment and sprinkler 1 smoke detectors have been installed on air conditioning vents, and the functions of air conditioning vents have been improved.
An air conditioning vent has emerged that can perform the functions of the other installed equipment mentioned above.

As shown in FIGS. 3 and 4, the air conditioning vent A is provided with an opening 31 at the bottom by a front plate 21, a back plate 22, left and right side plates 23, 24, and a top plate 25. A duct connection port 2 for connecting a duct 28 to a front plate 21 of a thin wave-shaped ventilation port body 20 having a hollow portion 26.
7, position the rectifying adjustment plate 30 near the opening 31 in the ventilation main body 20, and connect the left and right side plates 23 on both sides thereof.
．． 24, the shafts 29a and 29b are attached to the shafts 29a and 29b so that the angle can be changed.

The air conditioning vent A configured as described above is installed on the back side of the ceiling 40, for example, as shown in FIGS. 1 and 2, with the duct connection port 27 facing outward. The opening 31 is exposed on the ceiling 4o, and other equipment, such as a lighting fixture 41, is installed in an interior space B formed by the opposing air conditioning vents A, A, and AA.

In the above-mentioned known air conditioning vent A, the airflow guided into the air conditioning vent by passing through the duct 28 and the duct connection port 27 collides with the rectifying plate 30 during the passage.
It is inevitable that resistance will occur.

In addition, when the flow direction of the airflow is controlled by tilting the rectifying adjustment plate 30 as shown by the chain line in FIG. 4, the airflow collides with the adjustment plate 30 as shown by the arrow in FIG. particularly increases.

It is also known that when airflow passes through the air conditioning vent A, the greater the resistance, the greater the noise generated at the vent.

This invention can maintain the ventilation amount and directionality of the airflow sent out through the opening 31 from between the rectification adjustment plate 30 and the inner wall of the ventilation port body 20, reduce the resistance, and reduce the generated noise. The purpose of this invention is to provide an air conditioning vent that can be used for air conditioning.

This invention will be explained as follows with regard to the embodiment shown in the drawings.

As shown in FIGS. 5 to 7, the front plate 21 and the back plate 2
2. The left and right side plates 23, 24 and the top plate 25 form a thin casing-shaped ventilation port body 20 having a hollow portion 26 with an opening 31 provided below.

The opening 31 is formed by bending the front plate 21 and the back plate 22 inward to form a narrow opening.

The front plate 21 is provided with a duct connection port 27 for connecting to a duct 28 and guiding airflow into the ventilation body 20.

32 is a fixture for fixing the air conditioning vent to the ceiling 40, and 33 is a backing for making it tightly fit into the insertion hole of the air conditioning vent A provided in the ceiling.

The rectifying adjustment plate 30 is located inside the ventilation body 20 and close to the lower opening 31, and the left and right side plates 23 are placed on both sides thereof.
．． 24 so that the inclination angle can be adjusted.

The rectification adjustment plate 30 shown in the drawing has a horizontal strip plate 30b fixed to the lower edge of a vertical plate 30a in an inverted T-shape by welding, gluing, or other means, and extending the horizontal strip plate 30b to the left and right of the vertical plate 30a to protrude upward. The bearing portion 30C930C is formed by bending the bearing portion 30C930C. 30 c and left and right side plates 2
This shows an embodiment in which the shafts 29a and 29b are provided through the shafts 29a and 29b so that the angle of the rectifier plate 30 can be adjusted to maintain the desired inclination angle. It is not limited to the examples.

34 is a reinforcing plate.

In this invention, the vertical plate 30a of the rectification adjustment plate 30 is
A through hole 35 penetrating the front and back sides is provided.

The above-mentioned through hole may be one or many, and the installation position may be provided over the entire surface of the vertical plate 30a1 horizontal plate 30b, only the upper part of the vertical plate 30a, only the lower part of the vertical plate 30a, or the horizontal plate 30a. It may be provided only in 30b, and the shape of the through hole may be any shape such as a round hole, a strip hole, a square hole, a triangular hole, etc.

However, the total amount of air flow passing through the through hole 35 and the flow velocity are
Gap 36 formed by the inner wall 20a of the ventilation port body 20 and the leading edge of the flow adjustment plate 30 when the flow adjustment plate 30 is tilted
The number, position, size, and total area of the through holes are determined so that they are smaller than the total amount of air flow and the flow velocity sent out from the through holes.

The number, position, and area of the above-mentioned through holes are determined depending on the size of the air conditioning vent and the corresponding size of the flow regulating plate 30, but the flow regulating plate 30 of one type of air conditioning vent
The number, position, size, and total area of the through holes that satisfy the above conditions are derived experimentally. By providing a through hole 35 similar to the above, mass production becomes possible.

As described above, this invention provides a through hole 35 that passes through the front and back sides of the rectifying adjustment plate 30, so that the total amount of air flow and the flow velocity sent out from the through hole can be adjusted between the inner wall 20a of the ventilation body 20 and the rectifying adjustment plate 30. Since the through holes were determined to be smaller than the total flow rate and flow velocity of the air flow formed by the leading edge and sent out from the gap 36, the air flow that passed through the air conditioning vent was directed to the main body of the vent, as shown in Figure 8. The air is sent out from the gap 36 formed by the inner wall 20a of 20 and the leading edge of the rectification adjustment plate 30, and is also sent out from the through hole 35 of the rectification adjustment plate 30. Since the total amount of airflow and the flow velocity are kept small, the airflow is sent out in a direction according to the inclination angle of the rectification adjustment plate 30, and a part of the airflow that collides with the rectification adjustment plate 30 passes through the through hole 35. Since the resistance can be alleviated, the generation of noise can be made as small as possible.

As mentioned above, this idea aims to maintain the volume and directionality of the airflow sent out through the opening between the rectifier plate and the inner wall of the ventilation port body, while reducing the resistance and noise generated. There is an effect that can be done.
