Abstract
A smoke exhauster comprises an enclosure including a fan housing and a flood plate releasably secured thereunder. The enclosure has a plurality of spiral coupling recesses on the top plate for releasable securing the fan housing by a T-shaped fastener. The hood plate has at four corners a sliding catch member positioned in registry with the corresponding locking holes on the enclosure so as to permit the hood plate to be slidingly secured to the enclosure. The hood plate can be suspended from the rear of the enclosure if the sliding catch member on the rear is not intended to be disengaged. This arrangement provides faster and more convenient assembly or disassembly of the smoke exhauster for facilitating a rapid removal of the oil and grime accumulated on them.
