DETAILS OF DOMESTIC STOVES OR RANGES, OF GENERAL APPLICATION ## Abstract A cooking device is provided, which includes a cooking portion, a hood portion arranged on the cooking portion and provided with a suction port formed on one side thereof, and a driving portion configured to move the hood portion, wherein the hood portion is movable to any one of a first position in which the hood portion is accommodated in the cooking portion and a second position in which the hood portion projects from the cooking portion, and an angle of the hood portion is varied so as to change a direction in which the suction port is directed in the second position. ## Claims ### Claim 1 A cooking device comprising: a cooking portion; a hood portion arranged on the cooking portion and provided with a suction port formed on one side thereof; and a driving portion configured to move the hood portion, wherein the hood portion is movable to any one of a first position in which the hood portion is accommodated in the cooking portion and a second position in which the hood portion projects vertically from the cooking portion, and wherein an angle of the suction port is varied so as to change a direction in which the suction port is directed in the second position, wherein the driving portion comprises a first driving portion configured to move the hood portion to the first position, and wherein the first driving portion comprises: a driving source configured to generate a driving power, a worm gear disposed at a center of the hood portion, and configured to receive a driving power that is transferred from a driving source and to move the hood portion, at least two guide shafts provided in symmetrical positions about the worm gear, and a guide portion includes a worm gear hole configured to rotatably engaged with the worm gear and guide shaft holes configured to slidably coupled with guide shafts, wherein the driving portion further comprises a second driving portion configured to generate a rotating power to change the angle of the suction port against the cooking portion between a position vertically extended from the guide shafts and a position perpendicular to the guide shafts. ### Claim 2 (depends on 1) The cooking device as claimed in claim 1, wherein an angle of the suction port of the hood portion against the cooking portion is changed in a range of 0° to 90°. ### Claim 3 (depends on 1) The cooking device as claimed in claim 1, wherein the hood portion is hingedly connected to a part of the driving portion. ### Claim 4 (depends on 1) The cooking device as claimed in claim 1, wherein the hood portion is movable to a third position that is between the first position and the second position. ### Claim 5 (depends on 4) The cooking device as claimed in claim 4, wherein the angle of the hood portion is varied so as to change the direction in which the suction port is directed in the third position. ### Claim 6 (depends on 1) The cooking device as claimed in claim 1, wherein the hood portion is provided with a distance sensor arranged adjacent to the suction port to measure a distance between the suction port and a cooking vessel that is put on the cooking portion, and the distance sensor comprises a warning portion configured to warn a user when the distance between the suction port and the cooking vessel reaches a predetermined distance. ### Claim 7 (depends on 6) The cooking device as claimed in claim 6, wherein the warning portion is a display or a sound portion. ### Claim 8 (depends on 6) The cooking device as claimed in claim 6, wherein the hood portion further comprises a display configured to display the distance between the suction port and the cooking vessel, which is measured by the distance sensor, to the user. ### Claim 9 (depends on 1) The cooking device as claimed in claim 1, wherein the cooking portion further comprises a cover configured to cover the hood portion so that the hood portion is not exposed to an outside when the hood portion is in the first position. ### Claim 10 (depends on 1) The cooking device as claimed in claim 1, wherein the hood portion further comprises an illuminator arranged toward the cooking portion. ### Claim 11 (depends on 1) The cooking device as claimed in claim 1, wherein a suction force at the suction port is adjustable. ### Claim 12 A cooking device comprising: a cooking portion; a hood portion provided with a suction port formed on one side thereof and configured to be movable to any one of a first position in which a suction mode for inhaling polluted air that is generated from the cooking portion through the suction port is not performed and a second position in which the suction mode is performed; and a driving portion configured to move the hood portion, wherein an angle of the hood portion is varied so as to change a direction in which the suction port is directed in the second position, wherein the hood portion is arranged on a ceiling, is positioned adjacent to the ceiling in the first position, and descends by the driving portion to move to the second position in which the hood portion is adjacent to the cooking portion, and wherein the driving portion includes a first driving portion configured to move the hood portion vertically to the first position and the second position and a second driving portion configured to change the direction in which the suction port is directed, and wherein the first driving portion comprises: a driving source configured to generate a driving power, a worm gear disposed at a center of the hood portion, and configured to receive a driving power that is transferred from a driving source and to move the hood portion, at least two guide shafts provided in symmetrical positions about the worm gear, and a guide portion includes a worm gear hole configured to rotatably engaged with the worm gear and guide shaft holes configured to slidably coupled with guide shafts, wherein the second driving portion comprises a second driving portion configured to generate a rotating power to change the angle of the suction port in relation to the guide shafts. ### Claim 13 (depends on 12) The cooking device as claimed in claim 12, wherein an angle of the suction port of the hood portion against the cooking portion is changed in a range of 0° to 90°. ### Claim 14 (depends on 12) The cooking device as claimed in claim 12, wherein the hood portion is movable to a third position that is between the first position and the second position. ### Claim 15 (depends on 12) The cooking device as claimed in claim 12, wherein the angle of the hood portion is varied so as to change the direction in which the suction port is directed in a third position. ### Claim 16 (depends on 12) The cooking device as claimed in claim 12, wherein the hood portion is provided with a distance sensor arranged adjacent to the suction port to measure a distance between the suction port and a cooking vessel that is put on the cooking portion, and the distance sensor comprises a warning portion configured to warn a user when the distance between the suction port and the cooking vessel reaches a predetermined distance.
