In the disclosed invention, at least one of a first manipulation device and a second manipulation device comprises a dial for selecting one of two or more operation modes and a pushbutton for selecting one of two operation modes, and the types of operation modes selectable by the second manipulation device may vary according to operation modes selected by the first manipulation device, or the types of operation modes selectable by the dial may vary according to operation modes selected by the pushbutton.

First claim

1 .- 10 . (canceled)

11 . A movable hood comprising:
a main body having an accommodation space formed therein; a first fan accommodated in the accommodation space and configured to suction outside air in a first direction; and a second fan disposed not to overlap the first fan in the first direction, wherein the first fan and the second fan are arranged in a second direction orthogonal to the first direction, and wherein the second fan discharges the air suctioned outside the first fan in a direction between a third direction orthogonal to the first direction and the second direction and the first direction.

12 . The movable hood of claim 11 , wherein the second fan is accommodated inside the main body to be disposed at one side in the first direction more than the first fan.

13 . The movable hood of claim 11 , wherein a pair of the second fans are disposed to be spaced apart from each other in the second direction with the first fan interposed therebetween.

14 . The movable hood of claim 11 , wherein the main body is provided with an inlet forming a passage for allowing the outside air to flow into the first fan, and an outlet forming a passage for allowing the air suctioned into the first fan to be discharged to the outside of the main body,
wherein the inlet forms a passage for opening the main body in the first direction, and wherein the inlet forms a passage for opening the main body in the second direction.

15 . The movable hood of claim 11 , wherein the main body includes:
a case having an accommodation space formed therein and having an open one side in the first direction; and a cover configured to cover the case at one side in the first direction, and wherein an inlet forming a passage for opening the main body in the first direction is formed to pass through the cover in the first direction.

16 . The movable hood of claim 11 , wherein the main body further includes:
a case having an accommodation space formed therein and having an open one side in the first direction; a cover configured to cover the case at one side in the first direction; and a scroll disposed in a space surrounded by the case and the cover and having an inner circumferential surface formed in a curved surface surrounding an outer circumferential surface of the first fan, and wherein a pair of the second fans are disposed to be spaced apart from each other in the second direction with the scroll interposed therebetween.

17 . The movable hood of claim 11 , wherein a discharge port forming a passage for allowing the air suctioned into the second fan to be discharged to the outside of the main body, and
wherein the discharge port forms a passage for opening the main body in the third direction.

18 . The movable hood of claim 17 , wherein the discharge port is formed to pass through the main body in the third direction,
wherein the main body further includes a partition wall configured to block the second fan and the inlet, and wherein the discharge port communicates with a space in which the second fan is disposed.

19 . The movable hood of claim 11 , further comprising a louver protruding from the main body in the second direction at an unfolded location.

20 . The movable hood of claim 19 , wherein the discharge port forming a passage for opening the main body in the third direction is provided on the main body, and
wherein the louver is provided to cover a third surface outside the main body and move between a closed location at which the discharge port is closed and the unfolded location.

21 . The movable hood of claim 11 , wherein the second fan suctions the air from one side in the first direction and discharges the air in the third direction.

22 . The movable hood of claim 11 , wherein the second fan suctions the air from the other side in the first direction and discharges the air in the third direction, and
wherein an auxiliary inlet forming a passage for allowing the outside air to flow into the second fan is provided on the main body.

23 . The movable hood of claim 11 , wherein the main body includes:
a first case configured to accommodate the first fan; and a second case disposed to be biased to one side in the first direction more than the first case, wherein the first case and the second case are connected in the first direction, and wherein one side of the second case in the first direction is open.

24 . The movable hood of claim 23 , wherein an inlet is provided on the first case,
wherein the inlet is formed to pass through an end portion of one side of the first case in the second direction in the second direction, and wherein the second case is formed to protrude to one side in the second direction more than the inlet so that the second case blocks the inlet at one side in the first direction.

25 . The movable hood of claim 23 , wherein the second fan is accommodated in the second case,
wherein the cover is disposed between the first fan and the second fan, and wherein the second fan is accommodated in a space surrounded by the second case and the cover.

26 . The movable hood of claim 11 , further comprising: a grill configured to cover the main body at one side in the first direction and coupled to the main body; and
a filter disposed between the first fan and the grill and configured to filter the outside side suctioned into the first fan.

27 . A movable hood comprising:
a first fan configured to rotate about an axis in a first direction and to form a suction flow in the first direction; and a second fan configured to rotate about an axis in a second direction orthogonal to the first direction and form a discharge flow moving in a direction away from the suction flow as it moves away from the second fan in the first direction.

28 . A movable hood comprising:
a first fan configured to form a suction flow at a front side; and a second fan disposed at both sides of the first fan and configured to discharge air toward the front side at both sides of the first fan, wherein the second fan forms a discharge flow moving in a direction away from the suction flow toward the front side.

29 . The movable hood of claim 28 , further comprising:
a filter disposed at the front side of the first fan; and a case configured to accommodate the first fan, the second fan, and the filter, wherein the case is provided to be seated on the ground or a bottom surface.

30 . The movable hood of claim 29 , wherein the first fan suctions the air through a front surface of the case and discharges the air through an upper surface of the case, and
wherein the second fan suctions the air through a front surface or rear surface of the case and discharges the air through a side surface of the case.
