In general, restaurants and the like are provided with an exhaust device for discharging the smoke or smell generated when grilling meat or fish to the outside. In general, an exhaust system used in a general restaurant is a wall fan, and at least one fan is installed there through a wall to continuously discharge contaminated indoor air to the outside by driving the fan. However, such a wall fan has a limitation in completely exhausting smoke or odor continuously emitted while meat is being grilled, and smoke containing foreign substances remains in the indoor atmosphere, making the air muddy and sticking to the interior wall to hedge the interior aesthetics. It becomes.

Therefore, in order to solve the above problems, a roaster exhaust device has recently been proposed in which smoke or odor generated during meat grilling is locally discharged so that smoke or odor containing foreign substances does not remain in the indoor atmosphere.

As a roaster exhaust device, various configurations have been proposed through numerous known documents, including registration room 0329846 and registration room 0391741, but the overall configuration is a hood whose height is adjusted above the roaster placed on the table. The tube is placed adjacent, and the hood tube is connected to the hood main body which is fixed to the ceiling and insulates the fan, so that the smoke or odor generated as the fan blowing force in the hood body can be locally sucked and exhausted to the outside. It's about the same.
