Abstract

PURPOSE: To enable to perform the ventilation and exhaustion of exhaust gas and the absorption of exhaust noise simultaneously by a structure wherein a frame composed of bars is surrounded by sound absorbing material on its outer periphery with wire gauze between the frame and the sound absorbing material and a perforated tube windingly provided with cloth is insertedly fitted in the frame.
CONSTITUTION: The frame composed of the bars 1 is surrounded by the sound absorbing material 3 on its outer periphery with the wire gauze 2 between the frame and the sound absorbing material and the perforated tube 5 is insertedly fitted in the frame with a gap 8 between the sound absorbing material 3 and the perforated tube 5. Owing to the structure as described above, the exhaust gas produced in a kitchen enters in the perforated tube 5 and escapes to the gap 8 through small holes 9. At this time, the dew-distillating constituents in the exhaust gas such as steam, moist gas, oil mist and the like are absorbed by the cloth 4. Furthermore, when the exhaust gas flows out of the small holes 9 in the gap 8, the exhaust gas expands and as a result some plays are produced in the exhaust gas stream, resulting in silencing the noise and as well as the sound absorbing material absorbs the sound. In such a manner as mentioned above, the ventilation and exhaustion of the exhaust gas and the silencing of exhaust noise can be performed simultaneously.
