Description

  The present invention relates to an air supply weather cover unit including a pressure fan for preventing water leakage to the inside of a room of a building that requires air supply.

  In general, an air supply device equipped with a pressure fan that combines components such as a short wall penetrating tube, a shutter, a filter unit, and a pressure fan, will be exposed to water when it enters the interior due to rain, heavy fog, etc. In some cases, water leaks from the connecting parts and components in the room, and it is necessary to take measures against water leakage from the connecting parts and components.

  In general, for an air supply device equipped with a pressure fan, as a prior art, for example, when ventilating a warehouse, the inside of the warehouse is maintained in an appropriate temperature environment without moving the pressure fan even during the daytime. There has been proposed a ventilation method for the purpose of suppressing the running cost as compared to the conventional one (Patent Document 1). As another prior art, for example, a replacement ventilation system has been proposed in which the swirl component of the supply air can be further increased to increase the amount of swirling attraction and the airflow attenuation characteristics can be further improved (Patent Document 2). ).

And

  That is, the bottom of the wall through short tube and the filter unit is inclined, and the water entering the interior of the wall through short tube and the filter unit is naturally dropped through the inclined surface provided at the bottom. It is discharged outside the room via.

  In addition, the shutter of the component is configured to be disposed inside the wall penetrating short tube and the filter unit, so that even if water enters inside due to rain, dense fog, etc., the water will pass through the wall penetrating short tube. And it is discharged outside through the slope provided at the bottom of the filter unit, and water does not accumulate inside.

  In the present invention, the inclination provided at the bottom of the short through-wall pipe is an inclined structure with an appropriate angle so that the water accumulated at the bottom of the through-short pipe flows out to the outside on the outside air suction side of the air supply device by natural fall. The inclination angle, the properties of the inclined surface, and the shape or structure thereof can be arbitrarily designed.

  In addition, regarding the draining structure of the fixed rail part, the draining structure of the fixed rail part may be arbitrarily designed so that the accumulated water flows out by natural fall. In the present invention, in addition to the above-described components, arbitrary components can be appropriately combined and disposed as necessary.

The present invention produces the following special effects.
1) With a simple device, condensation near the outside air intake port of an air supply device equipped with a pressure fan can be prevented.
2) Water leakage to the inside of the room of a building can be prevented without reducing the efficiency of the air supply device provided with the pressure fan and without using energy.
3) Appropriate components such as a known air volume adjusting device and a filter unit for adjusting the amount of environmental air can be arranged as needed in places and areas where there is a lot of external dust, Rain, heavy fog, external dust, PM2.5, and the like can effectively prevent condensation and water leakage from occurring inside the room.
