Hereinafter, an air circulation device for agricultural and livestock buildings according to an embodiment of the present invention will be described with reference to the attached drawings.

The air circulation device for agricultural and livestock buildings according to an embodiment of the present invention includes a blower fan 30 and a blower guide (GD), as shown in FIG. 4, and connectors and fasteners to be described later. As shown, the blowing fan 30 consists of a motor 31 and a rotary blade 32 rotated by the motor 30. The blowing fan 30 is installed indoors in the agricultural and livestock building as shown. The blowing fan 30 may be installed in a building as shown in FIG. 4 and installed in the air supply opening 1a to supply outside air, or may be installed on the ceiling 1b of the building as shown in FIG. 6 .

The blower fan 30 blows indoor air from the bottom to the top by rotating the rotor blade 32, as shown in FIGS. 4 and 6. As shown in FIG. 8, the blower fan 30 may be shielded at the bottom with a wire mesh to allow ventilation. Since this blower fan 30 is a common device, its detailed description will be omitted.

The blower guide (GD) is installed at a distance from the top of the blower fan 30 as shown in FIG. 4 through a connector to be described later. As shown, the blower guide (GD) changes the blowing path of the indoor air blown by the blower fan 30 to the side of the blower fan 30 to circulate the indoor air of the agricultural and livestock building.

The blower guide (GD) is composed of a lower shell 10 and an upper shell 20 as shown in FIGS. 4 and 5. As shown, the lower shell 10 has a central portion 11 that is convex downward toward the blowing fan 30 and has a surface area that expands from the bottom to the upper portion of the central portion 11. For this purpose, the lower shell 10 The central portion 11 of the shell 10 is preferably formed in a fallopian tube-like shape as shown in FIGS. 4 and 7. As shown in FIG. 4 due to its shape, the lower shell 10 guides the indoor air of the agricultural and livestock building blown upward by the blowing fan 30 on the lower side to both sides of the central part 11. Accordingly, the lower shell 10 spreads the indoor air blown upward around the upper part of the central part 11, as shown.

The upper shell 20 is integrally coupled to the upper part of the lower shell 10, as shown in Figures 4 and 5, and shields the upper part of the lower shell 10. The upper shell 20 has a central portion as shown. (21) is formed to be convex upward and has a surface area that expands from the top to the bottom of the central portion (21). As shown in FIGS. 4 and 7, the height of the central portion 21 of the upper shell 20 is preferably formed lower than that of the central portion 11 of the lower shell 10, and the upper surface of the central portion 21 is gentle. It is more preferable that it is formed in a curved and streamlined form. Since this upper shell 20 has a closed upper part with a central portion 21, it prevents upper air from flowing into the lower shell 10. However, the upper shell 20 guides the upper indoor air or outdoor air in a streamlined manner through the central portion 21, that is, the upper surface, and spreads it around the central portion 21.

Here, the above-described upper shell 20 and lower shell 10 may be coupled by bolting as shown in FIGS. 4 and 7, and a space may be formed therein. In addition, as shown, the lower shell 10 may be open at the lower end of the central portion 11 and may be provided with a ventilation hole HL at the lower end. Accordingly, indoor air can be introduced into the lower shell 10 through the ventilation hole HL at the bottom. The lower shell 10 prevents indoor air from being overcrowded in the upper part as indoor air flows into the interior when the blower fan 30 operates. Therefore, the lower shell 10 smoothly diffuses indoor air.

Alternatively, the lower shell 10 may be configured in the same way as the above-described upper shell 20 and may be coupled to the lower part of the upper shell 20. That is, the lower shell 10 may be configured like the upper shell 20 shown with a closed top. In this case, the lower shell 10 may be blocked at the lower end with the central portion 11 formed in the shape of a fallopian tube as shown, or may be formed in a streamlined shape in the same manner as the upper shell 20 and blocked at the lower end. there is. In conclusion, the lower shell 10 can be formed with the lower end, which forms the end of the central portion 11, closed. This lower shell 10 guides air to the side of the central portion 11 through the closed end. Therefore, the lower shell 10 can guide air to the top and diffuse it even if the bottom is blocked.

Meanwhile, the above-described connector is a component for connecting the blower guide (GD) and the blower fan 30 in a spaced apart state. The connector can be composed of a connecting base 41 as shown in FIGS. 4 and 7. One end of the connecting rod 41 is integrally connected to the motor 31 of the blowing fan 30 as shown by bolting, and the other end is integrally connected to the lower shell 10 of the blowing guide (GD). Therefore, the connecting rod 41 connects the blowing fan 30 and the blowing guide (GD).

As shown in FIGS. 4 and 7, the connecting rod 41 is preferably made of a metal rod bent so that both ends are respectively bolted to the motor 31 and the lower shell 10. The connecting rod 41 is composed of a plurality of connections as shown in FIGS. 4 and 8. As shown, one end of these connecting rods 41 is installed at equal intervals along the outside of the motor 31 and the other end is fixed to the lower shell 10. It is preferable that the other end of the connecting rod 41 is fixed to the lower surface of the lower shell 10, as shown enlarged in FIG. 7.

The above-mentioned fastener is a component for integrally connecting the blowing fan 30 to the ceiling 1b or the air supply opening 1a of the agricultural and livestock building and fixing it to the ceiling 1b or the air supply opening 1a. As shown in FIGS. 4 and 7, the fastener is composed of a fixing bar 43 made of a bent metal rod similar to the connecting bar 41 described above. That is, the fixing bar 43 is configured in much the same way as the connecting bar 41. As shown, one end of the fixture 43 is integrally connected to the upper shell 20. The other end of the fixture 43 is integrally connected to the supply opening 1a or the ceiling 1b of the agricultural and livestock building, as shown in FIGS. 4 and 6. Therefore, the fixture 43 fixes the blower guide (GD) in a hanging state to the ceiling (1b) or the air supply opening (1a) of the agricultural and livestock building, as shown.

As shown in FIGS. 4 and 8, the fixing stand 43 is comprised of a plurality of units. As shown in FIGS. 4 and 7, one end of the fixture 43 is installed at equal intervals along the outside of the upper shell 20, and the other end is fixed to the ceiling 1b or the air supply opening 1a. It is preferable that the fixing stand 43 is fixed to the upper surface of the upper shell 20, as shown enlarged in FIG. 7.

It is preferable that the cutting portions 13a and 23a are horizontal and concave. These bolting portions 13a and 23a may be formed in a step shape as shown to accommodate the head or nut of the bolt.

And, as shown enlarged in FIG. 7, the connecting rod 41 and the fixing rod 43 are bent in a horizontal state so that their ends rest on the bolting portions 13a and 23a. The horizontally bent ends of the connecting bar 41 and the fixing bar 43 are bolted by bolts connecting the upper shell 20 and the lower shell 10, as shown in an enlarged view. Accordingly, the connecting stand 41 and the fixing stand 43 are coupled together to the blower guide (GD) when the upper shell 20 and the lower shell 10 are coupled.

In the embodiment of the present invention configured as described above, when the blower guide (GD) is installed at the lower part of the air supply opening (1a) as shown in FIG. 4, the indoor air that rises by the operation of the blower fan (30) is blown. It is guided upward along the central part 11 of the lower shell 10. As shown, the central portion 11 of the lower shell 10 gradually expands in surface area toward the top, thereby diffusing rising air to the outside of the upper portion. In other words, the lower shell 10 changes the blowing path of indoor air. Therefore, indoor air circulates smoothly through diffusion.

As shown in FIG. 4, the upper shell 20 shields the upper part of the lower shell 10 and prevents external air supplied to the lower part of the air supply opening 1a from being directly supplied to the lower shell 10. The upper shell 20 has a convex central portion 21 facing the center of the lower side of the air supply opening 1a, and the surface area expands from the top to the bottom, so that the external air discharged from the bottom of the air supply opening 1a is dispersed to the surroundings. spread it out Therefore, the outside air is circulated after heat exchange with the indoor air outside the upper shell 20.

As shown in FIGS. 4 and 7, the convex central portion 21 of the upper shell 20 is formed to be lower in height than the central portion 11 of the lower shell 10, and the upper surface is formed in a streamlined shape to prevent air from the upper portion. Guided in a streamlined manner. Therefore, the upper shell 20 easily diffuses the upper air.

Since the upper shell 20 and the lower shell 10 are empty as shown in FIG. 7, their weight decreases as space is formed inside them. Therefore, the blower guide (GD) can be easily installed by reducing its weight.

Meanwhile, the blower guide (GD) is connected to the blower fan 30 through a plurality of connecting rods 41 and to the ceiling 1b or the air supply opening 1a through a plurality of fixing rods 43, making it easy to assemble and It is installed. At this time, the connecting bar 41 and the fixing bar 43 are made of bent metal rods as shown in FIG. 8 and are installed in a spaced apart state, so that indoor air or outdoor air can be circulated through the spaced gap.

In addition, the connecting stand 41 and the holding stand 43 are bolted to the bolts connecting the upper shell 20 and the lower shell 10, as shown enlarged in FIG. 7, so that they are easily fixed to the blower guide (GD).

On the other hand, as shown in FIG. 7, the blower guide (GD) may be provided with a lower shell flange 13 and curved wings 15 on the lower shell 10. As shown, the lower shell flange 13 extends outward from the upper end of the central portion 11 formed in the lower shell 10 with a cross-section of approximately an inverted triangle. As shown, the lower shell flange 13 guides indoor air supplied to the top of the central portion 11 to the side of the central portion and spreads it.

As shown in FIG. 7, the curved wing 15 extends to have a downward slope at the end of the lower shell flange 13. As shown, the curved wing 15 supplies air guided to the edge of the lower shell flange 13 by guiding it in a curved shape toward the bottom. Accordingly, the lower shell 10 easily guides the air guided to the upper part of the central portion 11 downward.

On the other hand, the blower guide (GD) may be provided with an upper shell flange 23 on the upper shell 20 as shown in FIG. 7. As shown, the upper shell flange 23 is formed to extend outwardly at the bottom of the central portion 21 formed in the upper shell 20 with a roughly hemispherical cross-section. The upper shell flange 23 extends to the bottom of the central portion 11. The supplied indoor air or outdoor air is guided to the sides of the center and diffused.

As shown in FIG. 7, the upper shell flange 23 is formed to have a downward slope from one end connected to the central portion 21 of the upper shell 20 in the side cross section toward the outside. Therefore, the upper shell flange 23 easily provides indoor air supplied to the lower part of the central part 21 to the lower lower shell 10.

Here, the above-described upper shell 20 may be formed substantially the same as the lower shell 10, as shown in FIGS. 8 and 9, and a ventilation hole HL may be formed at the end of the central portion 21. That is, the upper shell 20 may have a ventilation hole HL formed at the upper end of the central portion 21 forming a convex end portion, as shown.

Indoor air or outdoor air flows into the upper shell 20 through a ventilation hole (HL). The upper shell 20 mixes the indoor air or outdoor air introduced into the interior space with the indoor air introduced through the aforementioned ventilation hole HL of the lower shell 10. In the case of outdoor air, it is cooled or warmed as it mixes with the indoor air of the lower shell 10. In this way, the mixed air is discharged to the outside and spreads indoors by the negative pressure generated when the blower fan 30 operates.

In the embodiment of the present invention as described above, indoor air can be diffused more easily as the lower shell 10 is provided with the lower shell flange 13 and the curved wings 15, thereby allowing smooth circulation of indoor air. You can.

In addition, since the upper shell 20 is provided with the upper shell flange 23, indoor air or outdoor air can be smoothly circulated downward. Furthermore, as the upper shell flange 23 is formed to have a downward slope, the upper shell flange 23 can be disposed more smoothly. Indoor air or outdoor air can be circulated to the lower part.

In addition, when a ventilation hole (HL) is formed in the upper shell (20), indoor air or outdoor air is supplied inside through the ventilation hole (HL), and the indoor air and the indoor air flowing into the ventilation hole (HL) of the lower shell (10) are supplied to the inside. They can be mixed, and thus the outdoor air or indoor air introduced through the upper shell 20 can be heat exchanged with the indoor air introduced through the lower shell 10.
