Rotary air curtain rang hood with oil fume filter device

Abstract

The invention provides a rotary air curtain rang hood with an oil fume filter device. The rotary air curtain rang hood comprises an engine cover, a fan, a suction pipe and an oil fume separation device, wherein a first flow divider and a second flow divider are respectively mounted on an outlet of the fan; the outlet of the second flow divider is respectively connected with a plurality of air supply ducts; a plurality of air supply columns communicated with the air supply ducts are mounted in the engine cover; each air supply column is provided with a strip-shaped nozzle; the airflow forms a rotary air curtain in the engine cover after coming out of the strip-shaped nozzles; one end of the suction pipe is connected with the oil fume separation device, while the other end of the suction pipe is arranged above the rotary air curtain; and an ejector pipe is connected on the outlet of the first flow divider and extends into the suction pipe. According to the rotary air curtain rang hood with an oil fume filter device, the rotary air curtain is formed in the engine cover, so that the spillover diffusion of oil fume can be effectively avoided in the cooking process, and the extracting rate of the oil fume is increased.

Description

technical field [0001] The invention relates to a kitchen utensil, in particular to a rotary air curtain range hood with a lampblack filtering device. Background technique [0002] At present, the oil fume of most range hoods is inhaled and discharged by the multi-leaf fan, which inevitably causes oil accumulation, drying, and scaling on the impeller, which is troublesome to disassemble and difficult to clean; in addition, the accumulated oil dirt also destroys the The dynamic balance of the impeller increases the running noise, affects the use effect and shortens the service life. Although most of the current air curtain type range hoods have an air curtain, its air curtain air outlet is on the front edge of the range hood and the lower sides of the casing on both sides, and the airflow is blown from top to bottom to form an air curtain. In this design, since the air flow direction of the air curtain is opposite to the upward direction of the oil fume, the effect of extrac...
