Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchange ventilator which is constructed of a decorative panel on the indoor side, and whose main body is attached to the back of a ceiling or the like, for performing air supply / exhaust ventilation accompanied by heat exchange by duct connection.

[0002]

2. Description of the Related Art The heat exchange ventilation device of this type is widely used as an air conditioning ventilation device for buildings and public facilities. The basic structure is composed of a box-type main body that is attached to the back of the ceiling and the like, and a decorative panel that is attached to the main body and that constitutes a substantial air supply and exhaust port on the ceiling surface. In the main body, two ventilation passages for air supply and exhaust, which are partially formed by each working fluid passage of the heat exchange element, are configured in an independent state, and a blower that forms an exhaust flow and a supply airflow are formed in each ventilation passage. A blower that forms the.

In the heat exchange ventilator having the above-mentioned structure, each ventilation passage of the main body is connected to the outside by a duct, and fresh outside air is supplied to the inside of the room, and the polluted indoor air is exhausted to the outside of the room. It is done through the element.

[0004]

The heat exchange ventilator as described above can perform air supply / exhaust ventilation with less fluctuation of state quantity such as indoor temperature, and since energy loss due to ventilation is small, ventilation in buildings and public facilities is reduced. It is suitable as a device.
However, since many things such as lighting fixtures and speakers for guide broadcasting have been conventionally installed on the ceiling in such places, the installation of the heat exchange ventilation device makes the ceiling surface more complicated and creates a harmonious indoor atmosphere. It tends to be difficult to form.

Since the heat exchange ventilation device has a wide duct piping space and a relatively large installation space for the main body, the space above the ceiling is suitable as an installation place in order to keep the room small. The ceiling is not always suitable as a place to install the 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 implementation, the speaker must be a speaker device with a speaker box, or a speaker box made of sound absorbing material or the like must be formed on the ceiling and the speaker must be attached.

[0006] It is an object of the present invention to provide a heat exchange ventilator capable of obtaining a simple and harmonious indoor atmosphere that does not compete with a speaker for a mounting location and that also functions as a speaker device.

[0007]

A heat exchange ventilator according to the present invention is installed in a space such as a space above a ceiling, and one end of each of two ventilation passages formed inside a surface on the indoor side is in a divided state. The main body of the heat exchange ventilator, which is open, and the duct connection ends of each ventilation passage are individually opened on the other side, is installed as a speaker box in the shape of a lid on the indoor side of the main body, and the ceiling is attached. A speaker is attached to a decorative panel provided along a surface or the like so that the speaker functions toward the interior.

In another heat exchange ventilator according to the present invention, particularly, the speaker is attached between the opening ends of the interior of the decorative panel, and the back of the speaker is wrapped with a sound absorbing member also serving as an arch-shaped ventilation guide. It is

[0009]

In the heat exchange ventilator according to the present invention,
Two independent air passages are built, a heat exchange element and a blower for intake and exhaust are built-in, and the main body box which is excellent in terms of acoustic effect with less resonance and less reverberation is attached to the decorative panel It becomes a suitable speaker box of the speaker, and it is not necessary to separately install the speaker for BG, guide broadcasting and other notification means.

Further, in another heat exchange ventilator according to the present invention, the sound absorbing member provided especially behind the decorative panel improves the acoustic characteristics of the speaker and smoothes the flow of the intake / exhaust flow in that portion.

The decorative panel 7 is provided with an exhaust air inlet 8 and an air supply outlet 9 which are open to the interior and are separated by a partition structure 10. The exhaust suction port 8 communicates with the open end of the exhaust ventilation passage opened on the lower surface of the main body box 1 on the back side of the decorative panel 7, and is arranged obliquely upward from below the heat exchange element 2. The exhaust air blower 3 is connected to the exhaust air outlet 6 through the working fluid passage. Further, the air intake port 5 is provided with the air blower 4 for air supply.
From the upper side of the heat exchange element 2 through the other working fluid passage arranged obliquely downward, through the opening end of the exhaust ventilation passage opened to the lower surface of the main body box 1 to supply air to the decorative panel 7. We are in contact with Exit 9. The exhaust ventilation passage in which the blower 3 for exhaust is incorporated is a passage for exhausting indoor air to the outside, and the intake ventilation passage in which the blower 4 for air supply is incorporated supplies the outside air to the room. Is a passage for
Both are independent of each other on all routes.

A speaker 11 is fitted and fixed on the decorative panel 7 between the exhaust suction port 8 and the air supply outlet 9 so as to be directed toward the room. Except for the front surface of the speaker 11, it is housed on the rear side of the decorative panel 7, and the sound absorbing member mounted on the rear surface of the decorative panel 7 along with the partition structure 10 separating the exhaust suction port 8 and the supply air outlet 9 from each other. It is wrapped with an arch-shaped sound absorbing member 12 formed of a sound absorbing material such as plastic. The sound absorbing member 12 improves the acoustic characteristics on the rear side of the speaker 11, reduces the supply / exhaust sound, and due to its shape, the flow of the exhaust flow from the exhaust suction port 8 to the open end of the exhaust ventilation passage on the main body 1 side. This is a configuration that fulfills the function of guiding airflow that facilitates the air flow.

The main body of the heat exchange ventilation device having the above-mentioned structure is installed in a space above the ceiling, and the air supply ventilation passage and the exhaust ventilation passage are connected to the outside by ducts to perform the heat exchange ventilation function.
