DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stirring / exhausting device for both above and below the ceiling, and more particularly, to prevent the stagnation of hot air in the summer above the ceiling, prevent the dew condensation action in the winter, and the north side below the floor. The present invention relates to an agitated and evacuated device that is used under and above a ceiling and under a floor for stirring and flowing high-humidity air in a portion that is difficult to ventilate, such as a facing corner.

[0002]

2. Description of the Related Art In recent years, wooden single-family houses and apartment buildings have been made low in height above the ceiling due to various conditions such as sunshine rights and a shortage of construction budget. The space above the ceiling is further narrowed because a storage case may be provided there. for that reason,
In summer, the strong sunshine raises the temperature of the space above the ceiling to an unusual level, resulting in the generation of radiant heat, and the interior becomes a suffocating living environment. To avoid this, the cooler is used for a long time, which not only increases the cost of cooling but also adversely affects human health. In order to overcome such a situation, the method conventionally employed is as follows. In the gable roof structure, the natural ventilation gallery provided at the center of the roof is removed, and an exhaust fan is attached.The air is sucked and exhausted from the suction port on the opposite side. When a fan is installed and the air is sucked from the eastern gallery, the distance between them becomes longer, so that the hot air near the center of the ceiling hardly moves, so that radiant heat cannot be removed. In addition, when installing an exhaust fan on the external wall, it is difficult to construct the groundwork and finish the technology without worrying about rain, and it becomes expensive.
And the ventilation function is insufficient. In the case of a roof with a ridge structure, the slope of the roof is small and gentle, so there is no space for installing an exhaust fan inside the natural ventilation opening of the eaves skylight. A product that satisfies various ventilation functions has not yet been developed. On the other hand, in winter, the ceiling becomes very cold at night. The temperature drops because the outside cold air penetrates through the roof material and penetrates into the ceiling. At this time, since the room is heated, the warm air rises and heat is transmitted through the ceiling plate to the space above the ceiling. Thus, the air behind the ceiling collides with cold air and warm air, and dew condensation occurs due to a temperature difference between the inside and outside, so that the air adheres to the wood part, causing various harmful effects such as wood decay, mold and pests. As for the underfloor exhaust fan, the conventional underfloor exhaust fan has a motor set on a cross fan, which is attached to the northern basic ventilation port, and is sucked and exhausted from the south side. And agitating it in multiple directions with a sirocco fan. However, in the case of the cross fan type exhaust, air cannot be passed to the places with the highest humidity, such as the central part under the floor, the two corners facing the north side, and the corner under the closet.

[0003]

SUMMARY OF THE INVENTION Accordingly, it is a first object of the present invention to provide an agitated / exhaust device that can be used both above the ceiling and below the floor and can be used both above the ceiling and below the floor. When used behind the ceiling, connect this device to the natural ventilation port attached to the eaves skylight with an exhaust duct in summer, agitate the hot air stagnant behind the ceiling, and allow the flowing air to flow from the exhaust duct to the outside. The present invention can prevent the outside of the ceiling from reaching an unusually high temperature due to the inflow of outside air from other eaves' skylights when it is discharged to the air, thereby contributing to the reduction of cooling costs for coolers and the maintenance of human health. Of the second subject. On the other hand, in the winter, the air above and below the ceiling collides with cold and warm air, which creates a temperature difference between indoor and outdoor areas, thereby preventing dew condensation from occurring, thereby preventing wood decay, mold and pests. This is a third object of the invention. When the device is used under the floor, this device is attached to the wood section below the floor, air is blown in multiple directions by the stirring sirocco fan and the air blow guide of the stirring section, and the air is stagnated in every corner under the floor, thereby stirring. The flowing air is exhausted from the exhaust duct connected to the air outlet to the outside by the exhaust sirocco fan of the exhaust unit, and the amount of outside air corresponding to the exhaust air is allowed to flow under the floor, thereby allowing the underfloor central part to be ventilated. It is a fourth object of the present invention to allow air to pass through the most humid places, such as the corners facing north and the corners under the closet.

[0005]

The present invention is a dual-use stirring and exhausting device which can be used both above the ceiling and below the floor, so that this device can be used both above the ceiling and below the floor as required. When used in the ceiling,
This device is connected to a natural ventilation port attached to the eaves skylight through an exhaust duct 11. In the summer, the agitating sirocco fan 5 rotates by the operation of the two-axis motor 3, and air is blown out in a plurality of directions from the plurality of outlets 13 along the blowing guide 12 of the stirring unit 2, and the hot air stagnates behind the ceiling. Is stirred.
At the same time, an air inlet 14 'formed in the lower panel 14
The air behind the ceiling is sucked in from. The air behind the ceiling, which is thus stirred and flows, is sucked from the suction port 8 formed in the exhaust fan outer frame 6 by the rotation of the exhaust sirocco fan 4 of the exhaust unit 1 and blows through the air guide 9. Exit 1
The air is discharged to the outside through the natural ventilation port through an exhaust duct 11 connected to the outlet 10. An amount of outside air commensurate with the amount of air discharged is sucked in from other eave skylights, so that the space above the ceiling can be prevented from rising to an abnormally high temperature. In winter, as mentioned above, the air above the ceiling collides with the outside cool air and the warm air from the indoor heating, and the temperature difference between the inside and outside causes dew condensation, which causes detrimental effects such as wood decay, mold and pests. However, in order to prevent such dew condensation, it is necessary to eliminate the temperature difference between the outside temperature and the room temperature. Therefore, the apparatus is operated during the time when the temperature difference is the most intense. For example, the operation time of the present apparatus is set as follows. Winter period: From 5:00 am to around 9:00 am and from 4:00 pm to around 10:00 pm, the time is set by the automatic rotation timer. When the apparatus is used under the floor, the apparatus is attached to a wood part to be attached, air is blown in multiple directions by the sirocco fan 5 for stirring of the stirring section 2 and the blower guide 12, and the air is stagnated at every corner under the floor, and is stirred. The exhausted sirocco fan 4 of the exhaust unit 1 discharges the air flowing through the exhaust duct 11 to the outside from the exhaust duct 11 connected to the air outlet 10, so that an amount of outside air commensurate with the exhaust air can flow under the floor. This allows air to pass through the hottest places, such as the central part under the floor, the two corners facing the north, and the corner under the closet. Even if the upper and lower positions of the exhaust unit 1 and the stirring unit 2 are exchanged, there is no difference in the operation and effect.

As a result, the air under the entire floor flows, and the flowing air is exhausted by the exhaust sirocco fan 4 of the exhaust unit 1 into the air suction ports 8 on the three side surfaces of the exhaust fan outer frame 6.
Then, the air reaches the outlet 10 through the air guide 9, passes through the exhaust duct 11 connected to the outlet 10, and is exhausted to the outside from the basic ventilation opening. Since an amount of external air corresponding to the exhaust air is sucked under the floor, ventilation is possible over the entire floor.
