For that reason, there is a concern that outside air is likely to flow in from the upper part of the opening portion 105. According to the booth 12 according to Embodiment 6, since the upper cover 160 covering the upper part of the opening portion 105 is provided, the inflow of outside air from the upper part of the opening portion 105 can be suppressed.
  • the air supplied from the ejecting device 120 is diffused up, down, left, and right.
  • a part of the air in the upper part of the opening portion 105 is dispersed in an upward direction without facing the suction device 130.
  • the air supplied from the ejecting device 120 can be straightened in the direction of the suction device 130.
  • the shape of the upper cover 160 is not particularly limited and is, for example, a plate member installed in the horizontal direction.

For that reason, there is a concern that outside air is likely to flow in from the upper part of the opening portion 105. According to the booth 13 according to Embodiment 8, since the wind speed of the air on an upper side of the opening portion 105 is faster than the wind speed of the air on a lower side, the inflow of outside air from the upper part of the opening portion 105 can be suppressed.

  • the configuration in which the wind speed of the air on the upper side is made faster than the wind speed of the air on the lower side includes not only means for increasing the linear velocity of the air on the upper side but also means for increasing the amount of air on the upper side.
  • the wind speed of the air suctioned by the suction device 130 may be a constant wind speed in the height direction, or the wind speed of the air suctioned on the upper side may be set to be higher than that on the lower side, similar to the air supplied from the ejecting device 120.
  • the wind speed of the air on the lower side may be set to be faster than the wind speed of the air on the upper side. Since the air supplied from the ejecting device 120 is lighter than the air in the external space, a tendency to flow upward is observed. Thus, in this case, the inflow of outside air can be suppressed by setting the wind speed of the air on the lower side to be faster than the wind speed of the air on the upper side.
