The utility model discloses a gas stove with an oil fume exhauster, which comprises a gas kitchen range, wherein, the gas kitchen range is horizontally fixed on the lower part of a cover body of which both side walls are internally provided with air exhaust passages, the bottom of the cover body is provided with an exhaust blower, and the air inlet of the exhaust blower is communicated with the air exhaust passages. The top of the cover body is in an arched sandwich structure, and the undersurface of the top of the cover body is provided with a plurality of air exhaust holes; the sandwich on the top of the cover body is communicated with the air exhaust passages through a U-shaped pipe, and a water filling pipe with a valve is arranged on the U-shaped pipe. With the adoption of the technical proposal, the gas kitchen range and a fume exhauster are combined into a whole, so the structure is compact. While in work, under the effect of the exhaust blower, the whole oil fume exhausting process is very smooth, and the oil dropping phenomenon caused by unfavorable oil fume exhaust can not occur. The water filling pipe with a valve is arranged on the U-shaped pipe, after impurities in oil fume are filtered through water, the impurities in the oil fume which is exhausted to the atmosphere are reduced as much as possible, and thereby, the environment is protected.
