Problems solved by technology
Generally, the oil fume absorption rate of traditional range hoods is about 70%. Due to the escape and diffusion of oil fume, the indoor air quality is poor, which not only endangers the health of the family, but also has oil stains everywhere on the wall; Separation, because only a small part of oil can be filtered out, the purification rate of the oil fume discharged outside is low, resulting in different degrees of outdoor environmental pollution
[0007] (4) Expenses for dismantling and cleaning: Due to the serious oil stickiness of the range hood, it is necessary to spend money to clean or replace the filter screen. Generally, users need to clean the range hood 2 to 3 times a year, and professional dismantling and cleaning are required, and the annual maintenance costs larger
[0008] Many researchers at home and abroad have carried out long-term and arduous research in order to reduce sticky oil, remove oil fumes, purify the air, protect the environment, improve efficiency, and reduce energy consumption. A series of measures such as installing a fume hood, using a filter, and separating fumes have achieved certain results, but because they have not jumped out of the traditional theoretical framework of using rotating impellers for energy transfer, although some performances have been improved and improved, However, no breakthroughs have been made

The invention discloses a structural high-efficiency and energy-saving oil-free range hood, which includes a fan, an oil filter, a hood casing, an oil hood, an illuminating lamp and a plurality of key-switches. The casing of the fan has a round double-cell or multi-cell structure with an air inlet and an air outlet; the impellers of the fan is composed of at least a group of arc-shaped passage vanes with single closed lateral and axial magnification. The main technical targets are as follows: the efficiency is improved by more than 10%, the energy is saved by more than 10%, the noise is less than or equal to 50dB, the oil absorption efficiency is more than 95%, the oil purifying rate is more than 90%, and the service life is improved by more than 3 times. The structural oil-free range hood also has the advantages of high efficiency, energy conservation, oil-freeness, clean and environment protection, convenient cleaning, etc., so as to be widely used in range hood manufacture for household kitchens, hotels, restaurants, dining halls, etc.; the comprehensive economic and technical indexes reach the leading level at home and abroad; the effects of energy conservation and emission reduction are prominent; and the economic benefits and the social benefits are remarkable.
Description
technical field [0001] The invention relates to a non-stick oil range hood, which belongs to the technical field of air purification. Background technique [0002] The range hood is a cleaning tool that uses electric power to drive a centrifugal fan to suck the fumes and harmful gases generated during the cooking process. In the daily cooking process, some oil fume will inevitably be generated. If it is not removed in time, it will accumulate over time and cause environmental pollution, making the white walls gradually turn yellowish brown, and the surface of clean utensils will also be greasy. Sexual smell will make the chef very uncomfortable. Therefore, the range hood that can get rid of the oil fume peculiar smell in time has almost become a necessity for every household, and is generally welcomed by people. According to statistics, the annual output of range hoods in my country reached 7.301 million units in 2005. [0003] At present, there are many types of range ho...
