Sirocco fan). 7
Denotes a solar cell provided on the back surface of the translucent member 2 (provided inside the air heat collecting device 1). In the embodiment of the present invention, in order to ensure the range of the air flow path Q as large as possible, the solar cell is provided near the exhaust port 5 and the fan 6 is provided on the back surface thereof. However, the positional relationship between the two is not limited to this. Although two fans 6 are provided in the drawing, one fan 6 may be provided depending on the capacity of the air heat collecting apparatus 1, and three or more fans may be provided when the capacity is large. The fan 6 is connected to the exhaust port 5
Provision in the vicinity has an effect that the warmed air in the heat collection chamber Y flows to the exhaust port 5 without stagnation. Reference numeral 8 denotes a heat insulating material provided inside the rear surface side of the air heat collecting device 1. Reference numeral 9 designates the interior of the air heat collecting apparatus 1 as two regions (front room X and heat collecting room Y).
This is a partition wall for partitioning. Reference numeral 10 denotes a second air inlet for sucking air inside the building. Numeral 11 denotes a damper for taking in and adjusting one or both of the outside air and the indoor air.

FIGS. 3A and 3B are plan sectional views of the air heat collecting apparatus 1. FIG. In the figure, reference numerals 9a and 9b denote ventilation holes formed in the partition wall 9. In the embodiment of the present invention,
Although two air holes are provided, the number of air holes increases or decreases depending on the capacity of the air heat collecting device 1 from the first. Further, in this drawing, the heat collecting plate 3 is formed in an uneven deck plate shape in a sectional view. The contact portion of the heat collecting plate 3 with the partition wall 9 does not cover the ventilation holes 9a and 9b, but is not limited to this.
As shown in (B), it may be formed so as to cover the ventilation holes 9a and 9b. The heat collecting plate 3 may have a heat collecting function such as a carbon net, and any type and material may be used as long as it has such a heat collecting function.
Therefore, the heat collecting plate 3 may be a material such as a perforated punched metal.

FIGS. 4A and 4B are enlarged views of FIG. The damper 11 includes a closing plate 11a and a lever 11b, and the closing plate 11a is rotatable in a double arrow direction about the hinge 20 by operating the lever 11b. Such an operation can be performed manually or by using an electric system (not shown). The closing plate 11a can also be stopped at a position between the double arrows as shown in FIG. 4B. Thereby, the outside air and the room air can be simultaneously taken in from the first intake port 4 and the second intake port 10 and fresh air having an appropriate temperature can be circulated from the exhaust port 5 into the room. The front room X located below the partition wall 9 uses the air collector 1 as a space for storing, for example, an air purifying material having a filter function for removing dust and dust floating in the outside air or room air. And
It is a space area for purifying dirty air. The heat collecting plate 3 may be arranged upright in the heat collecting chamber Y between the partition wall 9 and the exhaust port 5, or may be inclined. This makes it possible to heat the air in the air flow path Q more efficiently. Although the exhaust port 5 is provided on the back side of the air heat collecting device 1 in the drawing, it may be provided on the upper surface.

FIGS. 5 and 6 are schematic views of the air heat collecting apparatus 1 according to the present invention mounted on the outer wall or roof of a building.

Next, the operation of the air heat collecting apparatus 1 configured as described above will be described. The translucent member 2 is placed facing the sunlight so as to receive the sunlight. When only outside air is taken into the air heat collecting apparatus 1 and air is supplied into the room of the building, the damper is closed and the first intake port 4 is released by operating the lever 11b of the plate 11a. When the solar cell 7 is charged, the fan 6 starts operating, and outside air starts to be sucked into the first air inlet 4. In this case, if the outside air is contaminated by dust or the like, it flows toward the partition wall 9 while being filtered by the air purification material Z such as a filter filled in the front chamber X.
However, since the partition wall 9 is provided with the ventilation holes 9a and 9b, the air passes through the ventilation holes 9a and 9b and enters the heat collecting chamber Y regardless of the presence or absence of the air purification material Z. Then, it flows toward the exhaust port 5 through the air flow path Z before or after the heat collecting plate 3. Here, if the positions of the ventilation holes 9a and 9b are set to an appropriate interval (for example, three places at both ends and the center of the partition wall 9), the air entering the heat collecting chamber Y can be directed to the exhaust port 5 without stagnation. . The air thus heated is exhausted from the exhaust port 5 into the living room of the building. In addition, as shown in FIG. 3B, if the heat collecting plate is made to straddle the ventilation holes 9a and 9b, the heat efficiency of the air can be increased.

Next, when warming the air in the room of the building, the closing plate 11a of the damper is operated by operating the lever 11b to release the second intake port 10. At this time,
The first intake port 4 is closed. The subsequent operation of being exhausted indoors again through the indoor air exhaust port 5 is the same as described above. However, if the air purifying material Z is put in the front room X, the room air entering the front room X can be made clean.

Further, when it is desired to simultaneously inhale the outside air and the room air and exhaust the room indoors, the damper closing plate 11a is moved from the first air inlet 4 and the second air inlet as shown in FIG. The lever 11b is operated so as to be taken in. As a result, the same air circulation as described above can be performed.
