Oil smoke purifies all-in-one

Technical Field

The application relates to the technical field of oil smoke purification, in particular to oil smoke purifies all-in-one.

Background

A range hood is an electric appliance used in a kitchen for completely sucking substances such as oil smoke generated during cooking. The traditional range hood mainly has the function of suction and exhaust, namely, substances such as oil smoke in a kitchen and the like are sucked into the range hood and then exhausted into the outside air.

With the enhancement of environmental protection consciousness, the oil smoke in the industries of catering, food processing and the like is not allowed to be directly discharged, and the oil smoke in the industries of catering and food processing must be discharged after being purified. The traditional oil smoke purification treatment mode of connecting a smoke hood, an oil smoke purifier and a fan through a smoke pipe to perform suction and exhaust and purification treatment on oil smoke is gradually replaced by an oil smoke purification all-in-one machine integrating oil smoke suction and exhaust and purification into a whole due to high cost, complex manufacturing and installation, fire hazard in a smoke flue and the like. In order to better protect the environment, the oil smoke purification all-in-one machine does not exhaust to the outside by arranging a plurality of high-efficiency oil smoke filters, namely, an indoor circulating working mode is adopted to naturally protect the environment to the maximum extent; the oil smoke purification integrated machine adopting internal circulation to work without connecting an outer exhaust pipe is called an internal circulation oil smoke purification integrated machine in the market.

In order to efficiently remove suspended matters such as grease, smoke dust, water vapor and odor molecules in the oil smoke in the purification function, various efficient oil smoke filters such as a high-density mesh filter screen, a centrifugal oil throwing mesh disc, an electrostatic high-voltage electric field module, an active carbon odor removal mesh and the like are arranged on a flue at the front end of a fan in the existing oil smoke purification all-in-one machine in the market;

however, the high-efficiency oil smoke filters arranged in the front end flue of the fan can generate resistance to passing oil smoke gas while purifying the oil smoke gas, so that loss attenuation of the air pressure of oil smoke suction of the integrated machine is caused. Particularly, high-efficiency oil fume filters which filter oil fume gas by adopting an interception and adsorption principle such as a centrifugal oil-throwing screen disc, a microporous filter screen, a mesh filter screen, an active carbon odor removal screen and the like have higher filtering efficiency and larger wind resistance, so that the oil fume absorption efficiency of the existing oil fume purification all-in-one machine for efficiently filtering oil fume gas is generally low; and the suction force of the oil smoke purification all-in-one machine gradually attenuates and becomes smaller along with the increase of the wind resistance of the high-efficiency oil smoke filter in the using process.

Although the oil smoke suction efficiency can be improved by increasing the power and the size of the fan, the actual improvement is limited, and the problems of large volume of the oil smoke purification all-in-one machine or overlarge working noise and the like can be caused.
