Description

[Detailed Description of the Invention] Purpose of the Invention (1) Industrial Field of Application The present invention provides an intermediate duct interposed in the middle of a main duct for air conditioning, and a terminal duct connected to the intermediate duct to connect it to the ceiling of a building. The present invention relates to an outlet that penetrates into an opening in a plate and blows out conditioned air into each room, etc., and particularly relates to an outlet with detachable vanes having blades.

(2) Conventional technology In order to maintain a good air environment inside a building, an air conditioning duct is placed above the ceiling board, and the air outlet is inserted through an opening provided at an appropriate location in the building ceiling board. BACKGROUND ART It is widely practiced to supply air at a temperature and humidity suitable for the temperature conditions inside a building through this outlet to achieve air conditioning in a room.

Regarding this, as shown in Figs. 14 and 15, a terminal duct Di is constructed in the intermediate duct D, and a truncated pyramid-shaped outer frame F connected to this terminal duct is connected to the opening of the ceiling plate with its enlarged part. It is known that a cone portion C is installed in the expanded portion so as to be movable up and down.

This cone portion C has multiple cones with different expansion areas in order to uniformly blow out air into the room, etc.
It is formed by fixing Cm concentrically.

(3) Problems to be solved by the invention However, according to the above-mentioned air outlet,
First, the cone section C itself cannot be removed from the outer frame F, and once the air outlet is installed, the direction of the air flow is determined by the configuration of the cone section. It was difficult to do.

In addition, since the cone section C is constructed by fixing a plurality of cones Cm, each cone Cm itself cannot be moved after the air outlet is installed, so that the airflow can be adjusted according to the needs of the room, etc. It was impossible to finely adjust the blowing angle.

Furthermore, it is necessary to separately manufacture a plurality of cones Cm in advance and fix them concentrically to form the cone portion C, which requires many manufacturing steps and not only increases manufacturing costs but also relatively high material costs. I was getting used to it.

In addition, in view of the diversification of various values in today's mature cultural background, it is desirable to consider the total design of the room, etc. From this perspective, it is recommended to apply colored patterns and designs to the air outlets. Because it is necessary, in the conventional air outlet,
It was difficult to apply a design pattern to the entire exposed surface, such as the inside of the room.

In addition, since the cone portion C is movable up and down to adjust the blowout angle, a movable locking mechanism is required to lock the cone portion C after movement.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to form the cone portion from a single wing plate and configure it so that it can be attached to and detached from the outer frame, thereby making it extremely simple. With this configuration, not only can the blowout airflow direction be changed arbitrarily even after the blowout outlet is installed, but also the blowout angle can be arbitrarily finely adjusted for each blade individually, increasing the degree of freedom in adjusting the airflow direction and airflow distribution.
In addition, manufacturing costs and material costs can be dramatically reduced, a design pattern can be applied to the entire exposed surface such as the indoor side, and it is highly functional and practical as it does not require a movable locking mechanism. The purpose is to provide an air outlet.

Structure of the invention (1) Means for solving the problems In order to achieve the above object, the present invention provides a duct 1
The outer frame 16 is connected to the outer frame 16 and the outer frame 16 is detachably connected to the outer frame 16, and a wing section 24 is formed by carving slits 22 of various shapes in one thin plate.
4 and a vane plate 20 constituting a vane 28 whose vane traces 26 serve as ventilation ports.

(2) Function The air outlet of the present invention consists of an outer frame and a blade plate that can be attached to and detached from the outer frame. It includes a plurality of blades whose remains are used as ventilation holes after the blades are formed and pushed up.

Therefore, even after the air outlet is installed, by replacing the vanes, not only can the blowing direction of conditioned air be significantly changed, but also the blowing angle can be finely adjusted for each blade by simple manual work. is completed,
The degree of freedom in adjusting the airflow direction and airflow distribution can be increased.

At this time, the conditioned air passes through the main duct, the rectifier, the intermediate duct, and the terminal duct, and further circulates in the expansion direction in the outer frame, passes through the ventilation holes between the blades, and is diffused into the room.

Furthermore, the manufacturing, assembly, and assembly processes are significantly simplified.

Furthermore, various designed slits can be engraved on a single thin plate in consideration of the direction of the blowing air, and any desired design pattern can be applied to the slits by baking, painting, etc.

(3) Embodiments Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a schematic cross-sectional view of an air outlet section using an air outlet 10 according to the present invention, in which a cylindrical terminal duct 14 is installed in the middle of an air conditioning intermediate duct 12 installed in the attic of a building, etc. Intervention is provided. An air outlet 10 according to the present invention is connected to the end of this terminal duct 14.

That is, a truncated pyramid-shaped outer frame 16 is connected to the terminal duct 14 and is disposed with its enlarged part facing the ceiling plate opening 18, and the wing plate is arranged so as to close the enlarged surface end of this outer frame 16. 20 is attached and fixed with screws or the like. The air outlet 10 of the present invention is constituted by the outer frame 16 and the vanes 20.

FIG. 2 is a schematic structural explanatory diagram of the wing plate 20,
The wing plate 20 is formed by carving slits 22 of various types in a single thin steel plate to form a wing part 24, and the third, fourth,
5. As shown in the figure, a plurality of blades 28 are included in the blade traces 26 after the blade parts 24 are pushed up as ventilation holes.

In this embodiment, the vane plate 20 is configured in a rectangular shape, and further has a defining part 30 and four peripheral edges of the vane plate 20 so as to divide it into four equal parts. A slit 22 is carved in the cut portion.

The slitting is performed, for example, by laser, plasma, press processing, etc., and by this, an arbitrary engraved pattern can be obtained. In the embodiment, the slits 22 on the push-up side are carved perpendicularly to the direction connecting the center and each corner as shown by the broken line arrows, so that the slits 22 are spread in four directions as shown by the broken line arrows. This means setting the correct airflow direction.

Moreover, since this angle setting can be easily performed manually, the manufacturing process can be extremely simple. Furthermore, even after the blades 20 are attached to the outer frame 16 and the air outlets are arranged, a person who always enjoys this conditioned air can easily manually reset the desired angle and adjust the air outlet angle. That will happen.

The characteristic feature of the present invention is that the air outlet 10 is composed of an outer frame and a blade plate that is detachable from the outer frame, and the blade plate is formed by carving slits of various types in a single thin steel plate. A plurality of blades are formed by forming a wing portion, and the remains of the wing portion after the wing portion is pushed up serve as ventilation holes.

Therefore, unlike the conventional case in which the outer frame and the cone part are integrally formed, by attaching and detaching the vanes 20, the direction of blowing out the conditioned air can be changed significantly even after the outlet is installed. In addition, the blowout angle can also be finely adjusted for each blade by simple manual work, increasing the degree of freedom in adjusting the airflow direction and airflow distribution.

In this embodiment, the wing plate 20 is fixed to the outer frame 16 with screws, but it may be fixed with other attachment tools.

As a result, the blades 28 and the like can be easily cleaned by removing the blades 20, so that maintenance of the air outlet can be completed.

In addition, it has a separate structure, is lightweight, and has a simple structure.
Construction is also easy.

In particular, magnetic plates can be attached to the expanded end of the outer frame 16 or the four peripheral edges of the vanes 20 to make them not only detachable, but also detachable.

Here, the conventional mechanism for movably locking the cone portion is no longer necessary, and the blowing angle is adjusted with the vanes 20 fixed to the outer frame 16.

In addition, since the structure includes a removable vane with raised wing parts, there is no need for supporting members or reinforcing members for the cone part, which reduces pressure loss and increases the amount of air blown. The airflow diffusion radius can be made very wide. Therefore, compared to the conventional configuration, the amount of air to be processed is increased, and the opening surface is configured to have a smaller size.

Furthermore, since there is no need to provide a cone internal support frame, reinforcing members, etc. in the conventional cone portion, the generated noise can be made extremely small.

In this way, the slits can be arbitrarily configured in various ways, resulting in an excellent design effect from the interior decoration point of view.

For example, the slit configurations shown in Figures 6, 7, 8, 10, and 11 are for dispersion blowing in three directions, Figures 9 and 12 are examples for blowing in two directions, and Figure 13 is for blowing in one direction. It shows.

In addition to these, more complex designs and patterns can be freely engraved upon consideration of the direction of airflow.

Furthermore, in the present invention, it is possible to freely draw desired colored patterns etc. on the thin plate before forming the wings 28. As a result, it is possible to obtain a wide variety of air outlet designs that fully reflect the senses and tastes of the user. Then, the air outlet can be configured as a part of the entire room, which further enhances the desired design effect according to the elegance and atmosphere of each room, etc., and matches the total design of the room, etc.

Furthermore, when attached to a unitized ceiling such as a system ceiling, it is lightweight and therefore easy to transport from the factory.

In addition, the vane plate can be replaced with a desired slit-shaped vane depending on the season, and the air flow direction and design effect can be easily changed.

In the above-described air outlet configuration, as shown in FIG. 1, conditioned air flowing through the intermediate duct 12 from left to right in the figure passes through the rectifier 32, reaches the terminal duct 14, and further passes through the outer frame 16. The air flows in the expansion direction, passes through the ventilation holes between the blades 28, and is diffused into the room.

The air blowing angle and airflow distribution are finely adjusted by individually adjusting the opening degree of each wing 28 by manual operation according to the seating condition of the person enjoying the conditioned air in the room, desired airflow distribution, etc. That will happen.

After installing the air outlet, when it is desired to change the blowing direction, the airflow in the desired blowing direction can be easily generated by removing screws and replacing the vane plate 20.

As shown in Figures 16 and 17, slits can be easily carved so that the opening of the blades is directed toward the center, and in this case, the slits can be used as air outlets for spot cooling or heating. .

Incidentally, the air outlet according to the present invention can also be formed into a round shape. In this case, the vane plate 20 can be formed into a circle, and the slits can also be formed in a concentric shape.

Further, for example, a ceiling board in which the entire ceiling board is a single board to which lighting equipment, fire alarms, etc. are attached is also included in the present invention as long as it has the same structure as the above.

Effects of the Invention As explained above, the air outlet according to the present invention has an outer frame connected to a duct, and is removably connected to the outer frame, and has slits of various types carved in a single thin plate. The cone part is constructed integrally with the outer frame as in the past, as the cone part is constructed integrally with the outer frame as in the past. Unlike the previous model, it has an extremely simple configuration, and not only can the direction of the blowout airflow be changed arbitrarily even after the outlet is installed, but the blowout angle can also be finely adjusted individually for each blade, making it possible to change the direction of the airflow and the airflow distribution. The adjustment flexibility is increased, manufacturing costs and material costs are dramatically reduced, and there is no need for a movable locking mechanism.

In addition, when the slits are engraved, colored patterns can be freely drawn on the wing plate, and a design pattern can be applied to the entire exposed surface of the interior, etc., dramatically increasing the design effect of the interior. It becomes possible to change the design of the opening surface of the air outlet depending on the season so that it can be raised and incorporated as part of the overall design of the room or the like.
