Fire-extinguishing device for oil burner

An open-type oil burner comprising:

• a wick operating mechanism for raising and lowering a wick;
• a combustion cylinder construction having an opening provided at an upper portion thereof to discharge combustion gas therethrough to the interior of a room, said wick supplying fuel oil burned in said combustion cylinder construction to generate said combustion gas, and movement of said wick operating mechanism to a fire-extinguishing position causing said wick to be lowered such that a bad odor is generated in said combustion cylinder construction;
• damper means vertically movable in relation to said opening to substantially close said opening at the fire-extinguishing of said oil burner;
• an oxidation catalyst plate for removing said bad odor from combustion gas discharged from said combustion cylinder construction through said opening, said oxidation catalyst plate being carried on said damper means to discharge combustion gas therethrough to a room at the fire-extinguishing;
• a suction system for sucking up therein at least a part of combustion gas containing unburned fuel oil gas remaining in said combustion cylinder construction at the fire-extinguishing, said suction system comprising an air-tightly sealed tank arranged to be exposed to combustion heat from said combustion cylinder construction and communicated with said combustion cylinder construction;
• and,
• connecting means for connecting said damper means to said wick operating mechanism of said oil burner, movement of said wick operating mechanism to said fire-extinguishing position also causing said damper means to be actuated through said connecting means to substantially close said opening of said combustion cylinder construction such that combustion gas from said combustion cylinder construction is caused to pass through said oxidation catalyst plate where said bad odor is substantially removed therefrom.
