Abstract

The invention belongs to the technical field of household electrical appliances, and particularly relates to a range hood. The range hood comprises a motor, an impeller, a filter screen disc mounted at the front side of the impeller, and an oil guide ring which is arranged at the periphery of the filter screen disc, wherein a motor shaft of the motor separately drives the impeller and the filter screen disc; the filter screen disc is in engaged connection to the motor through a speed variator; and the speed variator regulates a transmission ratio between the filter screen disc and the motor shaft. The range hood disclosed by the invention realizes rotation speed regulation of the filter screen disc, improves oil smoke filter and separation effect, remarkably reduces noises generated in anoperation process of the range hood, facilitates improving the stability of the integral structure, and prolongs the service life. The range hood is simple in structure, and the filter screen disc isdismounted, cleaned, mounted and fixed conveniently and quickly.

Description

Technical field [0001] The invention belongs to the technical field of household appliances, and specifically relates to a range hood. Background technique [0002] Range hoods have become an indispensable kitchen equipment in modern households, and they are used more and more frequently, playing an important role in improving people's quality of life and maintaining physical health. [0003] The filtering and decomposing ability of the ordinary range hood needs to be improved, and the oil stain remains on the range hood, which is difficult to clean. In order to realize the cleaning-free function of the range hood, the ordinary range hood has been improved and innovated, and a new type of filter screen is installed. By installing the filter screen, the purification, filtration and decomposition efficiency of the oil smoke is improved, and the efficiency The oily fume remains, purifying the overall environment of the kitchen. [0004] However, the filter mesh plate is coaxially conn...
