Conventionally, air curtain devices include push-type air curtain devices that have an air outlet (air curtain outlet) on the ceiling side and blow out air toward the floor, and A push-pull type air curtain that is equipped with an air inlet (curtain outlet) and an air inlet on the floor, blows air from the air outlet toward the air inlet, and then draws this air through the air inlet to form an air curtain. The device is known.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air curtain device that solves the problems of the prior art by using the rising part of a staircase in a building as a suction part of the air curtain.

The present invention is a push-pull type air curtain device, which is used in a stair-type entrance of a building such as a stadium or a factory, in which an air outlet is provided above the stairs and an air inlet is provided at the rising part of the stairs.
以下、図面に基いて本発明を詳しく説明する。 Hereinafter, the present invention will be explained in detail based on the drawings.

ーカーテンの吸込口を示す。 FIG. 1 is a front view of a staircase section in which the air curtain device of the present invention is installed, as seen from the indoor side, and FIG. 2 is a side view. Reference numeral 1 indicates an air curtain outlet provided at the top of the stairs; 3 indicates the inlet of an air curtain which partitions the rising part of the staircase 2 with gold or punched metal.

される。 In the present invention, when there is no wind from the outside, the air is blown out from the air curtain outlet 1 and sucked in from the inlet provided at the rising part of the stairs. and fifth
Since the structure is such that the air is sucked in from the suction port of the stairs and exhausted from the bottom of the stairs to the ventilation equipment, an air curtain as shown by the solid line 4 in Figure 2 is formed, and outdoor air is drawn into the room. Intrusion is prevented.
Furthermore, when wind blows in from outside, even if the air curtain is bent inward due to the wind pressure, as shown by the two-dot dashed line in Figure 2, it will still be sucked in through the suction port provided at the rise of the bottom step of the stairs. Therefore, the air curtain is maintained and outdoor air is prevented from entering the room.
一方、本発明においてはエアーカーテンの吸込
