Environmentally-friendly circulating-type smoke exhauster

Abstract

The invention belongs to the field of household appliances, and relates to an environmentally-friendly circulating-type smoke exhauster. The environmentally-friendly circulating-type smoke exhauster comprises a main case and a smoke helmet connected with the main case, wherein the main case is internally provided with a first-stage cyclone separation filtering unit, a second-stage impeller centrifugal separation filtering unit and a third-stage static strainer filtering unit sequentially from bottom to top; the first-stage cyclone separation filtering unit comprises a separation cylinder of which the lower end is connected with an oil cup; the main case is fixedly provided with a motor; an impeller of the second-stage impeller centrifugal separation filtering unit is sleeved on an output shaft of the motor; the third-stage static strainer filtering unit comprises a strainer fixed on the main case; and the strainer is located on the outer side above an impeller cover. The smoke exhauster provided by the invention has a good purification effect, does not need a flue, accords with the environmentally-friendly requirements of low carbon and energy conservation, is unlikely to block and has long service life, and can be used for solving the problems that the smoke exhauster in the prior art is easy to block and poor in oil removal effect, needs an externally-arranged flue, and the like.

Description

Technical field [0001] The invention relates to the field of household appliances, in particular to a circulating range hood that does not require a flue exhaust duct and has little pollution. Background technique [0002] China’s kitchen fume pollution is very serious, which is determined by the Chinese eating habits. Cooking habits such as frying, frying, cooking, and frying make people suffer from oil fume. Therefore, what people pay more attention to is how to discharge as much oil fume as possible, and less attention is paid to the pollution of the atmosphere after discharge. [0003] China’s range hoods have only been developed for 20 years. The earliest range hoods were installed directly on the wall of the cooktop with a set of ventilating fans to achieve the effect of inhaling the range hoods. Later, the Chinese range hoods (hooded direct-mounted range hoods) ), then to the European-style range hood, and the "side-suction" range hood, which was newly launched in the past...
