Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a damper device attached to an air supply outlet for supplying air-conditioning air supply to a room and adjusting the amount of the air supply. In particular, the present invention relates to the structure of a damper device that facilitates the adjustment of the air volume and the attachment / detachment to / from the air outlet.

[Prior Art] For example, in a cold region, a large-scale heating device is installed outdoors, and warm air supplied from the heating device is guided to each room through a duct provided in a wall or ceiling. ,
Heating is performed by supplying warm air into the room from the air outlet, and a damper device for adjusting the air volume is attached to the air outlet.

As the damper device as described above, there is a circular damper or a rectangular damper, and in the case of a circular damper, through holes for air supply are formed radially at predetermined intervals,
A partition plate having the same shape as each through hole is rotatably attached to the back side of the through hole, and by rotating the partition plate, the cut-off area of each through hole is changed to adjust the air volume. , In the rectangular shape, slit-shaped through-holes are formed at a predetermined interval, and a partition plate for blocking the through-holes is movably attached to the rear surface side thereof, like the circular damper. The air volume was adjusted by sliding the partition plate to change the amount of blocking the through-hole.

Conventionally, when attaching these damper devices to the outlet,
As shown in FIG. 7, a frame body is attached to the ceiling plate 21 near the air outlet 20.
22 is attached, bolt holes 22a are provided at predetermined positions of the frame body 22, a flange portion 24 having bolt holes is formed in the damper device 23, and bolts 25 are screwed into these bolt holes to form a damper. The device 23 was attached to the air outlet 20.

[Problems to be Solved by the Invention] However, in the conventional damper device,
Since the air volume is adjusted by sliding the partition plate and changing the cut-off amount of the through-hole, whether the spacing of each through-hole is the same as the area of the partition plate covering them, that is, the area of each through-hole. Or the area more than that is required.

Therefore, there is a problem in that even if it is fully opened, the actual aperture ratio becomes one half or less, and the ventilation resistance is large.

Further, when dust or the like is accumulated in the through hole of the damper device 23 or the blowout port 22, it is necessary to regularly clean the damper device 23, and at that time, the damper device 23 is removed. In this case, it is troublesome to remove / attach the bolt 25, and there is a problem that the work is dangerous if the place is high such as the ceiling.

Further, since the flange portion 24 for mounting the bolt 25 is required around the damper device 23, the place where the opening / closing lever or the like for adjusting the opening degree of the lid member is mounted is limited, and the position of the blowout port 22 is limited. In some cases, for example, when the air outlet 22 is located near the wall surface, there is a problem that the operation becomes difficult to perform.

The present invention has been made in view of the above circumstances, and an object thereof is to have a large actual opening ratio at the time of full opening and therefore a low ventilation resistance, and moreover, a damper device can be easily attached / detached to / from an outlet. At the same time, another object of the present invention is to provide a structure of a damper device capable of arbitrarily changing the directions of the operation lever and the like.

[Means for Solving the Problem] The present invention provides a structure of a damper device that guides air sent from an air conditioner through a duct and adjusts the amount of air sent to the living room from its outlet. A large number of through holes for passing warm air are formed in almost the entire area of the damper substrate formed in a predetermined area covering the air outlet of the duct except for the peripheral portion thereof, and the entire area of the through hole is formed. A cover member having a cover size is attached via a hinge so as to be openable and closable, and the cover member is configured to adjust its opening and closing angle by an opening and closing means that slides along the side of the damper substrate. A pair of spring rods biased in a direction to spread on both sides are attached to the base plate, and a frame portion having an attachment hole into which the spring rod is inserted is formed at the bottom of the outlet of the duct. Characterized by To.

[Operation] According to the structure of the damper device of the present invention, by adjusting the opening / closing means on the side portion of the lid member, the lid member rotates about the hinge, and the damper surface on which the through hole is formed is formed. On the other hand, by adjusting the opening / closing angle, it is possible to adjust the blowing amount of the air sent from the through hole.

In this case, when the lid member is fully opened, the through holes are formed in almost the entire area of the damper substrate, so that the opening ratio is very large, the ventilation resistance is small, and efficient ventilation can be performed.

Further, when the spring rod of the damper device is inserted into the mounting hole provided in the air supply outlet in a folded state, the spring rod is urged in the direction of expanding to both sides, so that it spreads in the outlet. When the damper device is locked to the frame body and the damper device is pulled downward by a force that opposes the spring force at the time of removal, the spring rod is folded and can be easily removed from the mounting hole.
