Description

Description: TECHNICAL FIELD The present invention relates to an indoor ventilation device.

More specifically, the present invention relates to a central air-conditioning type ventilation device that uses cold and hot air or the like.

(Background Art) Conventionally, in a residential building, exhaust of a living room, kitchen, bathroom, etc. is usually performed individually by using windows, exhaust fans, and range hoods provided in the respective spaces. Also,
In a housing with few windows, such as an apartment building, although the indoor air supply is relatively taken into consideration, the exhaust gas is actually exhausted from only a few windows or an exhaust fan.

For example, as shown in FIG. 6, conventionally, an air supply / exhaust fan (a) is provided to supply air to a living room (a), a kitchen (c) and a sanitary part (d) through an air supply duct (e). However, regarding the exhaust, only the exhaust is done from the sanitary part (d) of the bathroom, toilet, etc. through the exhaust duct (f), and in other spaces, it is naturally exhausted through the space with the window. Often there is nothing but

However, in recent years, the airtightness of a house has been greatly improved, and it is necessary to sufficiently ventilate the living room and the corridor.

Despite the increasing need for such airtightness and indoor ventilation, it is difficult for the conventional housing structure and equipment to cope with this.

That is, if you try to force ventilation in the living room,
It is often difficult to pipe the air supply / exhaust duct in a narrow space above the ceiling due to the intersection of the ducts. Further, it is difficult to realize a method for efficiently supplying air into the living room and exhausting the air inside the living room, and further concentrating the exhaust air from all the rooms into the exhaust duct.

Therefore, as an alternative to the conventional house ventilation system, it has been desired to realize an indoor ventilation device that is more efficient and effectively uses a narrow indoor space.

The inventor of the present invention has diligently studied in order to solve such a problem, uses the space of the indoor down-ceiling part as the air supply passage, collects the exhaust gas in the living room in the corridor, and then the sanitary part. It was found that it is effective to recover it.

(Object of the Invention) The present invention has been made in view of the circumstances as described above, and improves the drawbacks of the conventional indoor ventilation device, and is efficient and easy to install even in a small indoor space. The purpose is to provide a new indoor ventilation system.

More specifically, the present invention provides a highly efficient and easy-to-install indoor ventilation device that uses a down ceiling space indoors for duct-saving air supply and that enables centralized exhaust of all rooms. Has an aim.

DISCLOSURE OF THE INVENTION In order to achieve the above object, in the indoor ventilation device of the present invention, a heat recovery heat exchanger and a blower fan, which are installed near the outer wall, are arranged in a circulation path of air communicating with each room. , Of the air circulation path, the intake path is provided in the interior space of the down ceiling provided in the upper part of the corridor and the side wall of the down ceiling,
The exhaust passage is formed by the inlet that communicates with each chamber.
It is formed on the inner wall surface of the building, connects the room and the corridor, and is installed in the interior space of the building that extends from the guide hole that guides the indoor air to the corridor to the sanitary section through the corridor and the interior space of the descending ceiling. , An exhaust duct extending from the sanitary portion to the heat exchanger and the blower fan.

The ventilation device of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view showing the overall outline of the indoor ventilation device of the present invention. For example, as shown in FIG. 1, a heat recovery heat exchanger (1) and a blower fan (2) installed in the vicinity of an outer wall such as a doorway of a house sucks heat from the outside to exchange heat. Qi blows into the interior space of the down ceiling (3). The blown air is supplied to the inside of the living room (4) from the side wall of the down ceiling (3), and conversely, the air in the living room is collected in the sanitary section (6) through the corridor (5) and the down ceiling (( The air is blown to the heat recovery heat exchanger (1) through the exhaust duct (7) installed in the internal space of 3). Then it is released outdoors.

The indoor ventilation device of the present invention is formed, for example, by forming an air circulation path as shown in FIG.

FIG. 2 is a sectional view showing the air supply / exhaust structure of the living room in the portion A of FIG.

Air is circulated in the space of the down ceiling (3) that serves as an air supply passage, and the air is guided into the living room (4) through the inlet (8) provided on the side wall of the down ceiling (3). On the contrary, the air in the living room (4) constitutes a part of the inner wall surface of the house, and is provided with a guide hole () in the door (9) or the partition (10) separating the living room (4) and the corridor (5). Discharge from 11) and 12) to the corridor (5).

The air discharged to the lower part of the corridor (5) is the sanitary part (6)
Through the holes or slits provided in the doors or partitions of the house, or through the internal space of the house due to the installation of an exhaust fan or the natural flow, etc. to the sanitary part (6), where it is concentrated and exhausted by the exhaust duct (7) .

Since only the exhaust duct (7) is provided as a duct in the space inside the down ceiling (3), there is no concern that the air supply duct and the exhaust duct will intersect and the piping will be disabled, unlike in the conventional case.

The guide holes (11) and (12) for exhausting air from the inside of the living room (4) to the corridor (5) are preferably inclined downward from the living room (4) toward the corridor (5). Further, it is preferable to provide a gallery (13).

This is because the guide holes (11) and (12) prevent sound and light in the living room (4) from leaking to the corridor (5). In this way, consideration must be given to maintaining privacy.

Of course, the guide holes (11) and (12) are not limited to the downwardly inclined ones as shown in FIG. Further, the shape of the guide hole and the place of installation can be made appropriate. Like the guide hole (11) shown in Fig. 2,
Not only does it have a straight downward slope, but the guide hole (1
As in 2), it may be a bent passage, or as shown in FIG. 3, it may be a guide hole (14) parallel to the floor surface, or as shown in FIG. A guide hole (15) for communicating the living room (4) and the corridor (5) can be provided on the floor without providing a guide hole in the door (9) or the partition (10) of the living room (4). .

In any case, it is necessary to select the shape of the guide hole, the installation location, etc. so that the exhaust gas in the living room (4) can be smoothly discharged to the corridor (5). It is necessary to prevent sound and light in the living room (4) from leaking to the corridor (5) in any of the various shapes of the guide holes.

To prevent sound leakage, make the guide holes longer,
It is also advantageous to use sound absorbing material to form the guide holes.
For example, the guide hole (11) shown in FIG. 2 may be inclined to make it longer, or the guide hole (12) may be formed by forming a bent passage to make it longer, or the guide hole (15) shown in FIG. like,
It may be a long passage. Use of a sound absorbing material, such as glass wool, for these guide holes becomes more effective. When a bend is formed like the guide holes (12) and (15), the sound absorbing effect becomes particularly large.

5 (a) and 5 (b) show an example in which the door (16) is provided with a bending guide hole (18) formed of glass wool (17). A gallery (13) is provided on the living room (4) side and the corridor (5) side.

It is also advantageous to use silicon rubber as the sound absorbing material. Using a silicone rubber sheet, for example,
The guide hole (14) may be parallel to the floor surface as shown in the figure. In this case, as shown in a cross section in FIGS. 6 (a) and 6 (b), a silicon rubber inner cylinder (19) made of a silicon rubber sheet having a thickness of, for example, 0.3 to 0.5 mm and a hardness of about 50 °,
Hard outer cylinder made of hard material such as plastic or metal (20)
It is possible to form a double-cylindrical guide tube consisting of and and to attach it to the guide hole of the door or partition.

As described above, by installing the guide hole of the present invention, it is possible to prevent the sound and light from leaking in the living room, and to effectively discharge the air in the living room, which is a major factor in realizing the indoor ventilation device.

(Effect of the Invention) As described in detail above, the ventilation device of the present invention enables duct-saving ventilation and efficient discharge of indoor air, which is essential for centralized ventilation of all rooms, to the corridor. .
Moreover, the installation of the guide hole of the present invention also prevents leakage of light and sound.
