Attach and discard with filter.
  • one or more pressure air tubes for blowing air from above the ceiling wall disposed above the middle plate to below the middle plate are disposed, and from a space where the pressure tube does not exist. Since the structure is such that the compressed air passing through the upper surface of the middle plate is blown toward the exhaust route, dirt such as oil smoke generated in the kitchen is sucked into the lower layer of the bottom plate, and then the negative pressure due to the gap around the outer periphery of the range hood. It is sent to the exhaust route by pressure and is discharged, and dirt from the kitchen cannot adhere to the wall of the range hood or the like.
  • the outer periphery of the ceiling wall is curved downward, and the dirt sucked toward the lower layer of the bottom plate passes through the inside of the curve and is discharged from the gap on the outer periphery of the range hood. Due to the structure sucked by the pressure, the compressed air that has descended from the fan outlet W in the compressed air supply tube 11 causes the oil smoke sucked into the lower surface of the bottom plate 3 to be compressed from the gap 7 on the outer periphery of the range hood as indicated by an arrow. It is transferred from the space between the supply cylinders 11 to the central exhaust duct D.
