Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blowout device with a damper for use in a room, which is provided in the ceiling of a house or a building and is connected to a ventilation duct for ventilation or cooling and heating. It is a thing.

2. Description of the Related Art Conventionally, in a building or the like, a ventilation device and an air conditioner are provided inside the ceiling, and air is blown into each room by a duct. In this type of blowing device, as shown in FIG. 3, a box 6 is attached to a mounting frame 3 fixed by a hanging bolt 2 in the ceiling 1 of a house or a building.
The ventilation duct 4 for ventilation or air conditioning is installed in the box 6
Connected to An outlet grill 8 is provided on the ceiling surface 7 of the box 6. The other side of the ventilation duct 4 communicates with a separately provided ventilation device main body (not shown) or cooling / heating device main body (not shown). The ventilation duct 4 is used to open and close the ventilation of the communication ventilation passage. An electric damper unit 9 is provided on the way of the electric damper unit 9, and the electric damper unit 9 is installed in the ceiling space 1 by being suspended by a hanging bolt 10.
By driving the damper 12 connected to 11 to set the ventilation path to the open A state or the closed B state, ventilation air or air for heating and cooling is supplied to the room 13 from the blowout grill 8, I am trying to stop the supply. Further, an inspection port 14 for inspecting is separately provided on the ceiling surface 7 below the damper unit 9.

[Problems to be Solved by the Invention] With such a conventional configuration, the box 6 is provided inside the ceiling space 1.
And there is a damper unit 9, which requires a lot of space. Further, there are problems that the ceiling grille 7 has an outlet grill 8 and an inspection port 14 which make the design unattractive, or the damper unit 9 and the box 6 are hung separately, which makes the construction complicated.

The present invention solves such a problem, and an object of the present invention is to reduce the size of the blowing device and simplify the hanging work.

Means for Solving the Problem In order to solve the problem, the present invention has a lower opening,
A box having an opening for duct communication on the side, and a frame-shaped mounting plate having an opening into which the box is inserted,
The mounting plate is integrally formed with an adapter mounting plate that abuts a side surface of the box having an opening for duct communication and has an adapter for connecting a ventilation duct at a position corresponding to the opening for duct communication. Arranges a cylindrical damper frame vertically, and a collar portion formed at the lower part of the cylindrical damper frame is brought into contact with the inner peripheral wall of the box below the duct communication opening, and the cylindrical damper frame is A disk-shaped damper is pivotally mounted so as to be horizontally and vertically positioned in the frame, and a damper motor for driving the damper is arranged at a corner portion in the box.

Operation With this configuration, when stopping the air sent to the room from the ventilation duct, the damper motor in the box is driven so that the damper is oriented horizontally and the air is closed in the box. The air is blown into the room from the blow-out grill through the damper frame in such a way that the air is oriented vertically. In addition, when performing maintenance on the dampers, etc., the work is performed by pulling out the box from the lower interior side.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 21 is a rectangular shape, and
A box with an open bottom, with a partition plate in one corner
21a is provided to form the triangular hollow portion 31. An opening for communicating the duct is formed on one side surface of the box 21. 24 is a rectangular opening 39 through which the box 21 is inserted.
The mounting plate having a box
An adapter mounting plate 23 is integrally formed that abuts a side surface of the duct 21 having an opening for communicating with the duct. An adapter 22 for connecting the ventilation duct 20 is provided at a position corresponding to the duct communication opening of the box 21 on the adapter mounting plate 23. The mounting plate 24 is fixed by a box mounting screw 25 to a fixing piece 24a formed by bending the lower portion of the box 21. A cylindrical damper frame 27 is vertically arranged inside the box 21, and a flange portion 26 provided at a lower portion of the damper frame 27 is brought into contact with an inner peripheral wall of a lower portion of an opening for communicating the duct of the box 21. I am letting you. Further, inside the damper frame 27, a disk-shaped damper 28 that opens and closes the ventilation path in the damper frame 27 is provided. Specifically, the damper 28 is pivotally supported by a rod-shaped damper shaft 29 fixed to the center of the damper 28, and one end of the damper shaft 29 is fixed to a partition plate 21a of a triangular hollow portion 31 at the corner of the box 21. Connected to. Therefore, this damper motor 30 is housed in the triangular hollow portion 31. The fixing piece 24a of the mounting plate 24 has a hole 32 for a hanging bolt.
, And hanging bolt 33 and fixing nut as shown in FIG.
The box 21 is hung and fixed by the inside of the ceiling 35 by means of 34. Ceiling surface of room 38 below the box 21
A blowout grill 37 is attached to 36. In the figure
40 is the structure of the building.

In the above configuration, when the air is blown into the room 38, the damper 28 becomes vertical and opens. That is, the ventilation duct 20
Inside, air sent to the room 38 from another ventilation device (not shown) or an air conditioner (not shown) flows into the upper part of the box 21 from the ventilation duct 20 via the adapter 22, and As shown by the dotted line in Fig. 2, the damper 28 is centered on the damper shaft 29 by the driving force of the damper motor 30.
It has rotated 90 ° and the damper 28 is open. Therefore, the air passes through the inside of the damper frame 27, passes through the lower portion of the box 21, and is blown into the room 38 from the blow-out grill 37.

Next, as shown by the solid line in FIG.
When is horizontal and is in a closed state, the air sent to the room 38 is closed, stays at the top of the box 21, and is not blown into the room 38.

When performing maintenance work on the damper 28 and the like, the blow-out grill 37 is removed from the room 38 side and the box mounting screw 25 is removed, whereby the entire box 21 can be pulled out downward. At this time, the mounting plate 24 and the adapter mounting plate 23 remain in the ceiling space 35 in a state where they are integrated. Therefore, the inspection can be performed with the outlet grill 37 removed, and only the box 21 is pulled down for inspection.

EFFECTS OF THE INVENTION As is clear from the description of the above embodiments, the present invention incorporates a damper into a box for indoor blowing, and integrates the electric damper unit and the box for indoor blowing to provide a blowing device within the ceiling. In addition to being downsized, the suspension work can be simplified.
