Abstract

Proposed is a method of controlling a portable air-flow guiding apparatus including adjusting at least one of an angle in a horizontal direction of a head unit including a sucking unit by a horizontal angle adjustment unit of the portable air-flow guiding apparatus and a height of the head unit by a height adjustment unit of the portable air-flow guiding apparatus according to a position of a heating source and a height of a cooking utensil.

First claim

What is claimed is:

1. A method of controlling a portable air-flow guiding apparatus, the method comprising:
measuring a position of a heating source by a heating source sensor of the portable air-flow guiding apparatus;
measuring a height of a cooking utensil by a distance sensor of the portable air-flow guiding apparatus; and
adjusting at least one of an angle in a horizontal direction of a head unit including a sucking unit by a horizontal angle adjustment unit of the portable air-flow guiding apparatus and a height of the head unit by a height adjustment unit of the portable air-flow guiding apparatus according to the position of the heating source and the height of the cooking utensil.

2. In the method of claim 1 , wherein the adjusting of the at least one of the angle in the horizontal direction of the head unit and the height of the head unit comprises:
adjusting an angle in a vertical direction of the head unit according to the height of the cooking utensil by a vertical angle adjustment unit of the portable air-flow guiding apparatus.

3. The method of claim 2 , further comprising:
inputting a start command for the portable air-flow guiding apparatus by operating an operation button of the portable air-flow guiding apparatus; and
adjusting positioning of the head unit to initial positioning according to the start command by at least one of the horizontal angle adjustment unit, the height adjustment unit and the vertical angle adjustment unit, wherein the measuring of the position of the heating source, the measuring of the height of the cooking utensil, and the adjusting of the at least one of the angle in the horizontal direction of the head unit and the height of the head unit are performed subsequently to the adjusting of the positioning of the head unit.

4. The method of claim 3 , wherein the inputting of the start command comprises at least one of the following:
inputting the start command by operating the operation button; and
inputting the start command from outside the portable air-flow guiding apparatus.

5. The method of claim 3 , wherein the adjusting of the positioning of the head unit comprises:
adjusting the height of the head unit to a maximum height by the height adjustment unit.

6. The method of claim 3 , wherein the measuring of the position of the heating source comprises at least one of the following:
measuring temperature of cooking heating equipment by the heating source sensor and thus measuring the position of the heating source; and
measuring the position of the heating source through operation in conjunction with the cooking heating equipment.

7. The method of claim 6 , wherein in the measuring of the temperature of the cooling heating equipment, the angle in the horizontal direction of the head unit is adjusted in a leftward-rightward direction by the horizontal angle adjustment unit, and thus the temperature of the cooling heating equipment is measured.

8. The method of claim 6 , wherein the measuring of the position of the heating source through the operation in conjunction with the cooking heating equipment comprises:
measuring a relative position of the portable air-flow guiding apparatus with respect to the cooking heating equipment by a position recognition sensor of the portable air-flow guiding apparatus;
rotating the head unit to the left or to the right in the horizontal direction by the horizontal angle adjustment unit on the basis of the relative position of the portable air-flow guiding apparatus; and
measuring the temperature of the cooking heating equipment by the heating source sensor and thus measuring the position of the heating source.

9. The method of claim 6 , wherein the measuring of the position of the heating source through the operation in conjunction with the cooking heating equipment comprises:
measuring a relative position of the portable air-flow guiding apparatus with respect to the cooking heating equipment by a position recognition sensor;
receiving in-operation cooktop information on a cooktop that is turned on, from the cooking heating equipment with which the portable air-flow guiding apparatus operates in conjunction; and
detecting the heating source on the basis of the in-operation cooktop information.

10. The method of claim 3 , wherein the adjusting of the at least one of the angle in the horizontal direction of the head unit and the height of the head unit comprises at least one of the following:
adjusting the angle in the horizontal direction on the basis of the position of the heating source by the horizontal angle adjustment unit;
adjusting the height of the head unit on the basis of the height of the cooking utensil by the height adjustment unit; and
adjusting the angle in the vertical angle of the head unit by the vertical angle adjustment unit in a case where a preset condition for vertical-angle adjustment is satisfied, on the basis of the height of the cooking utensil.

11. The method of claim 10 , wherein the adjusting of the angle in the horizontal direction is performed earlier than the adjusting of the height of the head unit and the adjusting of the angle in the vertical angle.

12. The method of claim 10 , wherein in the adjusting of the height of the head unit, the height of the head unit is adjusted on the basis of the height of the cooking utensil in such a manner that the head unit is vertically spaced by a preset optimal distance away from the cooking utensil.

13. The method of claim 12 , wherein the adjusting of the height of the head unit comprises:
adjusting the height of the head unit to a maximum height in a case where the height of the cooking utensil is greater than the maximum height minus the preset optimal distance; and
adjusting the height of the head unit to a minimum height in a case where the height of the cooking utensil is equal to or smaller than the maximum height minus the optimal distance.

14. The method of claim 10 , wherein the preset condition for vertical-angle adjustment includes a condition that a distance between the head unit and the cooling utensil is smaller at the maximum height of the head unit than the optimal distance.

15. The method of claim 13 , further comprising:
detecting a movement in a direction of the cooking utensil among movements of the portable air-flow guiding apparatus by a movement sensor of the portable air-flow guiding apparatus; and
adjusting the positioning of the head unit by at least one of the height adjustment unit and the vertical angle adjustment unit in a preset interference prevention mode in a case where the movement is detected.

16. The method of claim 15 , wherein the adjusting of the positioning of the head unit in the preset interference prevention mode comprises at least one of the following:
adjusting the height of the head unit to a preset interference prevention height by the height adjustment unit; and
rotating the head unit in the vertical direction and thus adjusting an angle of the head unit to a preset angle by the vertical angle adjustment unit.

17. The method of claim 16 , wherein in the adjusting of the positioning of the head unit in the preset interference prevention mode, at least one of the height of the head unit and the angle in the vertical direction of the head unit is adjusted in such a manner that a distance between the head unit and the cooking utensil is secured in a manner that is the same as a preset interference prevention distance.

18. The method of claim 15 , further comprising:
adjusting the positioning of the head unit to previous posit
