Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous ventilator with horizontal dampers, and more particularly to a continuous ventilator with sealing attachments adjacent to each damper.

In general, a continuous ventilator is one in which a horizontal damper is installed continuously in an opening in the roof of a building, as shown in Figure 1. , a gable plate 2, an outer plate 3, and a campshade 4 are provided, and as shown in FIG. It was configured by providing a horizontal damper 7.

However, when the dampers 7 are provided continuously in this way, unlike the case where the installation space of the dampers 7 is formed in advance with a member that takes into consideration the sealing with the dampers 7, as shown in FIG. A gap 8 is created between the side edge of the damper shaft support member 5 and the side edge of the damper shaft support member 5, and air for heating and cooling inside the building may leak from this gap. Light, dust, etc. may enter the building from the outside, and it has the disadvantage that it is not possible to completely isolate the inside and outside of the building.

The present invention was developed to eliminate the above-mentioned drawbacks, and when installing a continuous ventilator in a large opening in the roof, it is necessary to install a continuous ventilator in the building in order to eliminate the negative impact of dust etc. on the items stored inside the building. The purpose of the present invention is to provide a continuous ventilator equipped with a sealing attachment that can completely isolate the interior and exterior of the ventilator.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a continuous ventilator equipped with a sealing attachment according to the present invention will be described in detail with reference to the drawings.

In FIG. 3, the damper shaft support member 5 consists of two draining plates 1 ( Second
(see figure).

The damper shaft support member 5 is made of, for example, an angle material, as shown in FIGS. 4 and 5, and is stretched near the upper edges of the two facing drain plates 1, as shown in FIG. The ventilation opening is divided into a plurality of sections at equal intervals in the longitudinal direction (see FIG. 2).

A bearing 9 is provided at the center of the upper surface of the damper shaft support member 5, as shown in FIG. (See Figure 2).

This damper shaft 6 is used to interlock the opening and closing operations of a horizontal damper 7, which will be described later.

The damper shaft 6 has, as shown in FIGS. 3 and 6,
A horizontal damper 7 consisting of an ascending damper 7a and a descending damper 7b is attached by appropriate means such as welding or screwing.

The damper 7 is divided into sections between adjacent damper support members 5 and is continuously provided on the damper shaft 6 (see FIG. 2), and in the case of FIG. It is designed to rotate clockwise.

As shown in FIG. 3, a first sealing attachment 10 is attached to the damper shaft support member 5 on the side of the rising damper 7a.
It is protruded towards.

As shown in FIG. 4, this first sealing attachment 10 is formed with a substantially inverted cross-section, and its upper side edge 11 is fixed to the side of the rising damper 7a by appropriate means such as welding or screwing. The free edge 12 of the damper shaft support member 5 is fixed to the damper shaft support member 5 so that the free end 12 thereof can come into contact with the upper surface of the damper shaft support member 5, and is formed so as to close the above-mentioned gap 8 (see FIG. 2).

Note that the upper side edge 11 of the first sealing attachment 10 may be fixed to the lower surface of the rising damper 7a.

Damper shaft support member 5 between the descending dampers 7b, 7b
As shown in FIG. 3, a second sealing attachment 13 is provided on the upper surface of the holder, facing upward.

As shown in FIG. 5, this second sealing attachment 13 is formed into a V-shaped cross section with tongues projecting laterally from the upper edge of a channel-shaped member that opens upward, and its bottom 14 supports the damper. It is fixed to the upper surface of the member 5 by an appropriate means such as welding or screwing, and the free end edge 15 of the tongue piece can come into contact with the upper surface of the side of the descending damper 7b, so as to close the gap 8 mentioned above. is formed.

Therefore, when the damper 7 is closed, the
As shown in the figure, the first sealing attachment 10 and the second sealing attachment 13 can completely close the gap 8 (see FIG. 2) between the damper 7 and the damper shaft support member 5.

The plurality of dampers 7 are simultaneously operated to open and close by an appropriate opening/closing device (not shown) that is operated manually or driven by power.

In addition, in the above explanation, the case where the dampers are provided in one row in the longitudinal direction of the ventilation opening has been explained, but the present invention is not limited to this, and the case where the dampers are provided in two rows in the ventilation opening is also described. The same applies.

As explained above, in the present invention, sealing attachments 10 and 15 are provided on the damper 7 and the damper shaft support member 5, respectively, to close the gap 8 between the side of the damper 7 and the damper shaft support member 5. Even in the case where the damper 7 is installed continuously in a large opening, the installation space of the damper 7 is formed in advance in consideration of its airtightness, similar to a ventilation system.
can be completely blocked off, and the inside and outside of the building can be completely cut off.

Therefore, when the damper 7 is closed, air for heating and cooling inside the building can be prevented from leaking to the outside, and heating and cooling efficiency can be improved.

Furthermore, it is possible to prevent dust, smoke, harmful gas, etc. from entering the building from the outside.

Further, even when it is necessary to prevent outdoor light from entering the building from the outside as much as possible, the sealing attachment 10.15 can prevent light from leaking through the gap 8.

Further, even when the damper 7 is opened, the presence of the attachments 10 and 15 has the effect that the ventilation effect of the continuous ventilator is not diminished.
