Propeller-less drone using flow of wind

1. A drone with a wind guide, the drone comprising:

a body;

a single central inlet accommodated in the body, and comprising an inlet fan configured to generate wind to be introduced in the body;

at least two pairs of wind guides, each wind guide being spaced apart from the body; and

at least four connecting ducts, wherein

each of the at least four connecting ducts is connected with a respective wind guide of the at least two pairs of wind guides, and configured to transmit the wind introduced from the single central inlet to the connected respective wind guide,

each of the at least two pairs of wind guides is configured to apply lift force by discharging the wind transmitted from a respective connecting duct of the at least four connecting ducts, to allow the body to fly,

an interior of the body comprises a first accommodation part disposed at an upper portion of the interior a second accommodation part disposed at a lower portion, a partition wall that separates the first accommodation part from the second accommodation part, and

the first accommodation part is configured to introduce the wind and flow the introduced wind through the at least four connecting ducts to the at least two pairs of wind guides.

2. The drone as set forth in claim 1 , wherein the at least two pairs of wind guides comprise a plurality of wind guides extending radially from the body to be spaced apart from each other.

3. The drone as set forth in claim 1 , wherein each of the at least two pairs of wind guides comprises:

a supply part receiving wind from the respective connecting duct of the at least four connecting ducts;

a discharge part discharging the wind supplied to the supply part; and

a wind passage formed between the supply part and the discharge part to allow the wind to flow therethrough.

4. The drone as set forth in claim 3 , wherein each of the at least two pairs of wind guides is formed in a ring shape, and comprises an outer circumferential part provided on an outer circumference thereof, an inner circumferential part provided on an inner circumference thereof, an upper side part provided on an upper portion between the outer circumferential part and the inner circumferential part, and a lower side part provided on a lower portion between the outer circumferential part and the inner circumferential part, and

the supply part is formed on the outer circumferential part, the discharge part is formed on the inner circumferential part, and the wind passage is provided between the outer circumferential part and the inner circumferential part.

5. The drone as set forth in claim 4 , wherein the inner circumferential part comprises a first inner circumferential part formed in a direction from the upper side part to the lower side part, and a second inner circumferential part formed in a direction from the lower side part to the upper side part, and an upper portion of the second inner circumferential part extends inside the first inner circumferential part, and the discharge part is formed at a position where the first inner circumferential part faces the second inner circumferential part.

6. The drone as set forth in claim 5 , wherein the second inner circumferential part is formed to be inclined towards the outer circumferential part, thus allowing wind to be obliquely discharged from the discharge part according to an inclination angle of the second inner circumferential part.

7. The drone as set forth in claim 6 , wherein the inclination angle of the second inner circumferential part is formed such that it is closer to the outer circumferential part, as the second inner circumferential part approaches the supply part.

8. The drone as set forth in claim 5 , wherein a lower end of the first inner circumferential part is formed to be closer to the second inner circumferential part.

9. The drone as set forth in claim 3 , wherein each of the at least two pairs of wind guides is formed in a ring shape, and comprises an outer circumferential part provided on an outer circumference thereof, an inner circumferential part provided on an inner circumference thereof, an upper side part provided on an upper portion between the outer circumferential part and the inner circumferential part, a lower side part provided on a lower portion between the outer circumferential part and the inner circumferential part, and the wind passage provided in a space between the outer circumferential part and the inner circumferential part, and

the supply part is formed on the outer circumferential part, and the discharge part is formed on the outer circumferential part or on the lower side part.

10. The drone as set forth in claim 1 , wherein the single central inlet further comprises:

an inlet motor rotating the inlet fan.

11. The drone as set forth in claim 1 , wherein the single central inlet is configured to be controlled by wirelessly transmitted manipulation signal.

12. The drone as set forth in claim 1 , further comprising at least four tilters,

wherein each of the at least four tilters is positioned between one of the at least four connecting ducts and the respective wind guide of the at least two pairs of wind guides, and

wherein the at least four tilters are configured to be tilted to adjust angles of the at least two pairs of wind guides.

13. The drone as set forth in claim 1 , further comprising a battery installed in the second accommodation part for powering the single central inlet.

14. The drone as set forth in claim 1 , further comprising at least four tilters,

wherein each of the at least four tilters is positioned between the body and one of the at least four connecting ducts, and

wherein the at least four tilters are configured to be tilted to adjust angles of the at least four connecting ducts.
