The housing includes a peripheral wall for defining the opening thereof and includes a peripheral flange extended inward of the opening thereof for supporting the filter device in the opening of the housing.
The filter device includes an upper portion having a fence extended upward there from for confining a grease collected in the upper portion of the filter device within the filter device.
The filter device includes a first side having the latch extended therefrom, and includes a second side opposite to the first side thereof, the smoke exhauster further includes a retainer secured to the housing and engaged in the opening of the housing for receiving the second side of the filter device.
The retainer is pivotally secured to the housing and includes an L-shaped cross section for engaging with the second side of the filter device. The biasing means includes at least one spring provided between the retainer and the second side of the filter device for biasing the latch into the depression of the housing and to secure the filter device to the housing.
