Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a conditioned air outlet device that is suspended in the ceiling for air conditioning and heating.

(Prior art) Conventionally, the air outlet or suction port formed on the ceiling surface was
They are connected to ducts by repeatedly attaching them to the duct using complicated means such as hanging them in the ceiling with multiple hanging bolts, and in particular, the work of forming elongated linear air outlets or suction ports requires complicated on-site operations. , a damper that adjusts the amount of air supplied from the duct, a chamber that distributes the air, and an elongated outlet are each supplied with screws, etc., and the on-site operation is complicated, and the chamber As a mere air reservoir, it only converts dynamic pressure into static pressure, and a decrease in the air volume at the elongated outlet was unavoidable.

In order to eliminate the above-mentioned inconveniences during on-site work, we bring pre-fabricated parts to the site and simply assemble them on-site, making it easy to install a long, thin line-shaped air outlet or suction port on the ceiling. The present applicant previously proposed a connection unit that can be formed in the ceiling, fixed in the ceiling with a single hanging bolt, and easily adjust the amount of ventilation. I proposed the one described in .

(Problems to be solved by the invention) The above-mentioned conventional type has a cylindrical body that is connected to a duct in the ceiling, and has a special cross-sectional shape in which an elongated air outlet or suction port is formed on the bottom surface of the cylindrical body through a specially shaped communication casing. The bodies are connected to form a line-shaped outlet or suction port, but the communicating casing and the elongated casing are both rectangular and have been specially processed to connect them, making them difficult to handle. Not only did it take time and effort to transport each part separately to the site, but it also took time and effort to connect the parts together on site.

In addition, since the air outlet from the communication casing has a nozzle shape, the air is distributed even to the elongated end due to static pressure. It is unavoidable that there will be a difference in air volume between the ends, and if sufficient air volume is obtained at the ends of the outlet, there will be excessive air volume at the center, resulting in wasted power costs for the blower. No consideration was given to making the air distribution uniform.

(Means for Solving the Problems) The present invention reduces the number of component parts of the above-mentioned conventional air outlet unit, facilitates the manufacturing and processing of these parts, and therefore facilitates construction on site, and also reduces the number of blown air. The purpose is to improve distribution, and it has a cylindrical body 1 with a connecting tube 2 for the duct protruding from one side, the upper surface closed with a top plate 3, and the lower surface 4 open.
An adjustment cylinder 7 having a window hole 6 which overlaps and communicates with the inner end opening 5 of the connecting cylinder 2 is provided rotatably inscribed therein,
At the lower end of the circular body 1, a ventilation hole 9 is provided which is long in the direction perpendicular to the axis of the circular body 1 and whose opening width gradually increases from the center to both ends along the length of the wall surface. A branch connection pipe 11 in which a blowout pipe 8 with a circular cross section is provided in the middle part with a wind direction plate 10 whose installation angle can be changed along both outer sides in the installation direction.
It is characterized by being connected and connected.

(Function) The blow-off unit according to the present invention connects the cylindrical body to the cylinder 2.
Connect to duct a and install hanging bolt 1 in ceiling b.
2, and connect the blowout pipe 8 to the lower opening 4 of the cylindrical body. In this case, as shown in FIG. Alternatively, as shown in Fig. 5, it can be used horizontally so as to face the opening c of the side wall d of the step formed on the ceiling, and by rotating the adjustment tube 7, the opening 5 of the connecting tube 2 and the window hole of the adjustment tube 7 can be used. The amount of ventilation from the duct a is adjusted by adjusting the degree of opening caused by the polymerization with the duct a, and the air is blown out from the ventilation holes 9 arranged in the length direction of the blow-off pipe. By changing the mounting angle, the blowing direction of the blown air can be changed.

In addition, the blow-off pipe 8 may be used singly as shown in FIG. 2, or a plurality of blow-off pipes may be used in a straight line as shown by the phantom lines in FIG. If there is only one tube, the openings at both ends of the tube 8 are closed with blind plates 13.

(Example) Embodiments of the present invention will be described with reference to the drawings.

1 is a cylindrical body with a connecting tube 2 for the duct a protruding from one side, the upper surface is closed with a top plate 3, and the lower surface 4 is open, and therein is a window that overlaps and communicates with the inner end opening 5 of the connecting tube 2. A cylindrical adjustment tube 7 having a hole 6 is provided rotatably inscribed, and the adjustment tube 7 is connected to the operation piece 7.
The opening 5 is rotated by a and the window hole 6 overlaps with the opening 5.
By adjusting the degree of overlapping communication between the cylinder body 1 and the duct a, the amount of air flowing between the cylinder body 1 and the duct a is adjusted. It was decided to hang it in a fixed position in the ceiling.

A linear outlet is constructed by connecting a horizontally long outlet pipe 8 to the lower end of the cylindrical body 1, and the outlet pipe 8 is made of a circularly wound single plate or a spirally wound circular cross section. A pipe of a predetermined length is used, and is connected to the lower opening 4 of the cylindrical body 1 along a horizontal direction perpendicular to the axial direction of the cylindrical body 1 through a branch connecting pipe 11 provided at an intermediate portion thereof.

The blow-off pipe 8 is provided with a large number of ventilation holes 9 along the length of the pipe as shown in FIG. 3, or long slit-shaped ventilation holes continuous in the length direction (not shown). 9 was opened, and the opening width of the vent hole 9 gradually increased from the center of the tube 8 toward both ends. Along both outer sides of the ventilation hole 9 in the arrangement direction, the sixth
Two wind direction boards 10, 10 as shown in the figure or a wind direction board 10 formed in a rectangular cylinder shape as shown in FIG. The direction of the wind blowing can be adjusted by changing the angle of the installation depending on the situation.

(Effects of the invention) According to the present invention, a linear air outlet can be easily formed on the ceiling surface by directly connecting the air outlet pipe to the cylindrical body, and the air outlet pipe is a straight pipe with a circular cross section. Therefore, commercially available round pipes can be used, making it very economical and easy to process.Also, since the ventilation holes are simply drilled in the circular straight pipe, it is also easy to process, and the blowout pipe can be removed from the cylindrical body. Due to the shape of the lower half of the tube, the air flowing into the tube is naturally squeezed at the bottom and concentrated in the area where the vent is located, and the vent gradually widens from the center of the tube toward both ends. Since the opening is small just below the joint with the circular body, a large amount of air flows to both sides without being blown out immediately due to the ventilation resistance, and an average blowout distribution can be obtained over the entire length of the pipe. It has the effect of being able to adjust the blowing direction of air using the wind direction plate.
