Abstract: An improved fume exhauster includes a housing forming therein a receiving space in which a suction and filtration unit is disposed. Fastened to the lower portion of the receiving space of the housing is a bottom plate having a fume sucking hole and a plurality of air exit holes arranged at a predetermined interval along left, right and front edges thereof. The fume is sucked in through the fume sucking hole of the bottom plate and is subsequently filtered by a filtration member. The filtered fume (clean air) is caused to pass through the air exit holes to form an air curtain under the fume exhauster. The air curtain acts to prevent the dissipation of the fume so as to reinforce the sucking and exhausting effect of the fume exhauster.

The top plate has a base plate portion provided respectively at the left side thereof and the right side thereof with a second vertical strip portion extending downwards. Each of the U-shaped members has a middle plate portion provided respectively at the left side thereof and the right side thereof with a first wall plate portion and a second wall plate portion, which extend upwards such that they are curved and that they are corresponding to each other. The U-shaped members are so disposed that the first and the second vertical strip portions are received in the slots of the U-shaped members with an appropriate tightness.

Abstract: This invention is directed to smoke exhauster having two side members and a top plate. The side member includes a main portion having a plurality of horizontal rods disposed on an internal wall and a top portion. Both left and right edges of the top plate are bent downwardly to form a vertical plate portion having a plurality of through holes corresponding in location and number to the horizontal rods. A plurality of bolts pass through the through holes and are threaded to the horizontal rods.

Abstract: An external body of a soot extractor for effectively devoid of the previously mentioned sharp edges which are capable of inflicting injury on persons. The body includes a top sheet member having left and right edges bending downwardly to form a first fixing means respectively, and two side sheet members respectively attached to the left and right sides of the top sheet member and individually having a main plate portion and a arcuate plate portion, and a second fixing means extending downwardly from the edge of said arcuate plate portion for secured on the first fixing means.

Abstract: A fume extractor comprises a housing and a predetermined number of suction devices. The housing has a bottom board provided with fume sucking ports. Each of the suction devices comprises a motor provided with a rotating shaft upon which a wind impeller is mounted in such a manner that the wind impeller is corresponding in location to the fume sucking ports of the housing. Each of the suction devices is further provided with a filtration member having a top segment and a bottom segment which are fastened respectively to a top board and a bottom board of the housing. The filtration member has an inner wall that is located at a distance from the wind impeller. The housing is further provided with a plurality of exhausting holes.
