Voice regarding the operating information is also output from the speaker 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation device (including an air-conditioning ventilation device) whose interior side is made up of a decorative panel and whose main body is attached to a ceiling or the like.

[0002]

2. Description of the Related Art This type of ventilation system is widely used as a ventilation system for buildings and public facilities. Basically,
A main body having a ventilation function that is attached to the ceiling and the like, and a muffler box that is connected to the main body by a duct and has a decorative panel that constitutes a substantial air supply / exhaust terminal portion on the ceiling surface of each room The configuration and the main body having a ventilation function are provided with a decorative panel that constitutes a substantial air supply / exhaust terminal portion on the ceiling surface or the like.

The ventilator having the above-mentioned structure is installed facing the inside of the room, and performs the ventilation of the room by supplying the outside air into the room or sucking the room air from the decorative panel part constituting the air supply / exhaust terminal part. Will be done.

[0004]

The ventilation device as described above is suitable as a ventilation system in offices, public facilities, buildings and the like. However, the ceiling in these places
Since many things such as lighting fixtures, loudspeakers for guide broadcasting and fire protection devices have been conventionally installed, the ceiling surface becomes more complicated when installing an air supply / exhaust box, and it tends to be difficult to form a harmonious indoor atmosphere. is there.

Since the ventilation device also requires a duct piping space, the ceiling above the ceiling is suitable as an installation place in order not to narrow the room, but for example, the ceiling is not necessarily suitable as a mounting place for the audio device. That is, most of the ceilings of buildings are continuous spaces, and if you ignore the acoustic effect of this space, the sound of the speaker attached to the ceiling of a particular room will echo in other rooms, and the sound itself will It will be of poor quality. Therefore, in actual construction, the speaker must be a speaker device with a speaker box, or a speaker box made of a sound absorbing material or the like must be formed on the ceiling and the speaker must be attached.

Therefore, for the purpose of eliminating the complexity of the ceiling surface and the like, a ventilation device has been developed in which a speaker is incorporated in a decorative panel and functions satisfactorily as a speaker device.

An object of the present invention is to expand the function of a ventilation device equipped with a speaker.

[0008]

The ventilator according to the present invention is a ventilator in which a speaker is functionally attached to a decorative panel, and the speaker is used as a general audio output section of a notification device, a broadcasting device, or the like. In addition to being configured, it is configured as a voice output unit that is connected to a control circuit included in the ventilation device and outputs operation information output from the control circuit.

[0009]

In the ventilator according to the present invention, the speaker attached to the decorative panel can output general voice output such as BG and guide broadcasting, and can also inform the operating information of the ventilator by an easy-to-understand voice output. it can.

1 is a vertical sectional front view of an air supply / exhaust box in a ventilation system according to an embodiment of the present invention, and FIG. 2 is a block diagram of a signal system relating to a speaker of the ventilation system.

The illustrated air supply / exhaust box is connected by a duct to a ventilation device having an air blowing capacity for forming an air supply / exhaust flow as an indoor side terminal part of a ventilation system. Its basic structure is usually the same as well known. That is, as shown in FIG. 1, a rectangular box-shaped lower open box structure is formed,
On a main body box 2 which constitutes a ventilation passage or a chamber having a sound absorbing material 1 stretched on the inner surface, a connection port 3 which is connected to a ventilation device and serves as a supply air intake port or an exhaust outlet is provided on one side face thereof so as to be duct connectable. Has been. A decorative panel 4 is attached to the lower surface of the main body box 2 like a lid, and is attached detachably along the ceiling surface. A gap 5 between the decorative panel 4 and the main body box 2 is opened in the room and functions as an exhaust suction port or an air supply outlet.

The decorative panel 4 has a speaker 6 in the center thereof.
However, it is fitted and fixed while being directed toward the indoor side. Other than the front part of the speaker 6, it is housed on the back side of the decorative panel 4. On the back surface of the decorative panel 4, an umbrella-type sound absorbing member 7 made of a sound absorbing material such as sound absorbing plastic is attached, which connects a gap 5 between the decorative panel 4 and the lower surface of the main body box 2 to the center of the inside of the main body box 2. The back surface of the speaker 6 is wrapped with the sound absorbing member 7.

As shown in FIG. 2, an external audio signal 8 is input to the speaker 6 as a general audio output unit of a notification device, a broadcasting device, etc., and is output from a control circuit 9 provided in the ventilation device. The audio output of the driving information is input. That is, the external audio signal 8 is input to the speaker 6 via the signal adding means 10, and the control circuit 9
The output of the driving information (information relating to the operating status and failure status of the ventilation device) is input to the speaker 6 from the signal adding means 10 via the audio signal generating means 11.

In the air supply / exhaust box having the above structure, the main body box body 2 is attached to the space above the ceiling, and the connection port 3 is connected to the ventilation device by a duct to serve as a supply air supply portion or an exhaust air intake portion of the ventilation system. The decorative panel 4 is attached to the lower surface of the main body box 2 along the ceiling surface, and the gap serves as an air supply outlet or an exhaust air inlet to supply fresh outside air into the room or suck in polluted room air. Become. At this time, the umbrella-shaped sound absorbing member 7 serves to guide and smooth the flow of the airflow flowing through the portion to and from the gap, and at the same time, functions to reduce the airflow noise. The speaker 6 incorporated in the decorative panel 4 is connected to an output system of an audio device or a broadcasting device and independently outputs a normal sound as a general sound output unit. Further, the output related to the operating information of the ventilation device output by the control circuit 9 of the ventilation device is converted into an audio signal by the audio signal generating means 11, and is output as a sound from the speaker 6 through the signal adding means 10 for easy understanding. It will be notified in the form.

Although the above-described embodiment is an application example in the air supply / exhaust box, it is applied in the same manner as the embodiment even in a ventilation device or an air conditioning ventilation device in which a speaker is attached to the main body of the ventilation device. be able to.

[0016]

As is apparent from the above description of the embodiments, according to the present invention, the general sound output such as music and guide broadcasting can be output from the speaker attached to the decorative panel, and the ventilation device can be used. The driving information can be notified by an easy-to-understand audio output format, and the function of the ventilation device is expanded.
