Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic opening / closing air supply device provided on an outer wall of a building or the like for supplying outdoor air into a room.

[0002]

2. Description of the Related Art Conventionally, as a method of improving ventilation in a building and eliminating indoor air pollution (humidity, carbon dioxide gas, etc.), a method of opening an outer wall and providing an air supply device in this opening has been adopted. ing. For example, as described in Japanese Utility Model Laid-Open No. 63-82137, a louver having a plurality of blades inclined at an angle is provided on the indoor side of the air supply device, and the inhaled air is supplied indoors. It is designed to be introduced in a certain direction. Further, there is a louver whose angle can be changed manually.

[0003]

However, as described in Japanese Utility Model Laid-Open No. 63-82137,
In an air supply device provided with a louver, if the louver is fixed, cold outside air is introduced only in a certain direction in the room, and a local temperature change of the indoor air occurs, which makes the human body feel cold. Things happen. As a result,
There is a concern that a person in the room may experience discomfort or a physiological disorder.

Further, in the above air supply device, there is also used a device which is provided with a damper which can be manually operated so that it can be opened and closed as needed, but it is inadvertently left in the closed state. However, there is still a problem that air pollution in the room is caused by insufficient ventilation.

The present invention was made by paying attention to the above-mentioned problems, and an object of the present invention is to solve these problems, and when a person is indoors, automatically The present invention provides an automatic opening / closing air supply device in which the air supply device is closed and when the person is not present in the room, the air supply device is automatically opened to supply the outside air to the room. .

[0006]

In the automatic opening / closing air supply device of the present invention, the automatic opening / closing air supply device is attached to an opening of an outer wall or the like and is provided for supplying outdoor air into a room. A damper having a drive unit inside a tubular body of the air supply unit, and a motion sensor that transmits a signal to the drive unit to automatically open and close the damper by interlocking with each other are provided on the indoor side. And

In the automatic opening / closing air supply device of the present invention, the human sensor is a detection sensor for detecting infrared rays generated by the human body, and the detection sensor and the damper are linked to automatically open and close the damper. This is for automatically supplying the outside air.

That is, when the presence of a person in the room is detected by the detection sensor, the damper is operated to automatically close the air supply port, and it is detected that there is no person in the room. In the above, the damper is operated to automatically open the air supply port.

[0009]

In the automatic opening / closing air supply device of the present invention, a damper having a drive device in the tubular main body of the air supply device and a signal is transmitted to the above-mentioned drive device indoors to automatically open / close the damper. When the presence of a human presence sensor is detected, that is, when the presence of a person in the room is detected, the damper is actuated to automatically close the air supply port, and there is no person in the room. In this state, the damper is activated to automatically open the air supply port, so that the indoor air is always fresh without causing the human body to feel uncomfortable due to cold outdoor air. It is possible to keep.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of the automatic opening / closing air supply device of the present invention. In FIG. 1, the air supply device 10 includes an outer wall 11
Provided in the opening 11a of the cylindrical body 12, the hood 13 provided on the outdoor side of the outer wall 11, the louver 14 provided on the wall surface of the indoor side, and the tubular body 12 housed inside. And a damper 15.

The plate-shaped damper 15 is driven to open and close by a driving device 15a provided at the lower portion thereof. A human sensor 16 is connected to the driving device 15a of the damper 15 by a lead wire 17 near the lower end of the louver 14 on the indoor side, and the damper 15 is opened and closed by interlocking.

A judgment circuit for issuing an instruction to open / close the damper 15 is built in the driving device 15a.

Further, the motion sensor 16 has a capability of detecting infrared rays generated by a person in a wide range from directly below the air supply device 10 in the room to a wall surface facing the air supply device 10. In Example 16, a pyroelectric infrared sensor was used for 16.

FIG. 2 is a front view of the opening / closing mechanism of the damper 15, and FIG. 2 (A) shows the state where the damper 15 is opened by the drive of the driving device 15a, and the cylindrical main body 12 is located outside. Outside air can be supplied to the indoor side while being completely communicated with the indoor side. In addition, (B) of FIG.
With the damper 15 being closed by the drive of the drive device 15a, the outdoor side and the indoor side of the tubular body 12 are almost completely closed, and the supply of outside air to the indoor side is stopped. There is.

A human sensor 16 of the air supply device 10 of the present invention.
The pyroelectric infrared sensor used for this is a type that does not emit a signal when a person does not move. Therefore, if the presence of a person is detected and a signal is transmitted once in the determination circuit, the damper will be used for 30 minutes thereafter. 15 is in a closed state. On the contrary, when a person goes out of the room, the motion sensor 1
No signal is transmitted from 6 and 30 minutes after the last signal is transmitted, the determination circuit is designed to drive the driving device 15a to determine that there is no person and open the damper 15.

[0016]

In the automatic opening / closing air supply device of the present invention,
A damper having a drive device in the tubular body of the air supply device;
Due to the presence of a human sensor that sends a signal to the driving device and automatically opens and closes the damper by interlocking with the inside of the room, that is, when the presence of a person in the room is detected, the damper is When the human body is detected to be absent in the room, the damper is operated to automatically open the air supply port. It is possible to always keep the indoor air fresh without giving the discomfort caused by the cold outdoor air. Therefore, it is preferably used as an automatic opening / closing air supply device.
