Abstract
A woodstove emission controller for conveniently drawing emissions from the wood-stove so that the emissions do not enter the room where the wood-stove is located. The woodstove emission controller includes a tubular member having an inlet end, an outlet end and a bore extending therethrough; and also includes a closure member securely disposed in the bore near the outlet end for preventing a back-draft of emissions; and further includes a fan member securely and rotatably disposed in the bore for drawing emissions in through the inlet end and out through the outlet end of the tubular member; and also includes a motor mounted to the exterior of the tubular member, a belt member carried by the motor and the fan member, and a switch for energizing the motor.
Claims11
A wood-stove emission controller comprising:
- a tubular member having an inlet end, an outlet end and a bore extending there-through and being adapted to be securely amounted in a pipe of the wood-stove;
- a closure member being securely mounted in said bore of said tubular member near said outlet end for preventing a back-draft of emissions;
- a fan member securely disposed in said tubular member for drawing smoke through the pipe;
- a means for actuating and driving said fan member;
- wherein said means for actuating and driving said fan member includes a housing which is securely mounted to an exterior of a side wall of said tubular member, a motor being securely disposed in said housing and having a motor shaft and a shaft member, and a switch for energizing said motor;
- and
- wherein said fan member includes a cylindrical frame having a top ring member, a bottom ring member, a plurality of blade members disposed parallel to a longitudinal axis of said tubular member and securely interconnecting said top ring member to said bottom ring member and being spaced along a circumference said cylindrical frame, said fan member further including a cross member having ends securely attached to said bottom ring member, said fan member also including said shaft member securely attached to said cross member and extending co-axially of said tubular member.
