  • the invention relates to a structural high-efficiency energy-saving non-stick oil range hood, belonging to the technical field of air purification.
  • the range hood is a cleaning tool that uses electric power to drive a centrifugal fan to pump soot and harmful gases generated during cooking.
  • some fumes will inevitably be generated. If it is not removed in time, it will cause environmental pollution after a long period of time, making the white walls gradually become yellowish brown, and the surface of the clean utensils will be greasy and stainy.
  • the smell of sex makes the chef very uncomfortable. Therefore, the range hood that can eliminate the odor of soot in time is almost a necessity for every household, and is widely welcomed by people. According to statistics, in 2005, the annual output of China's range hoods reached 730.10 million units.
  • range hoods At present, there are many types of range hoods that have been developed and used, and their outer structures are common type, deep cover type and deep cabinet type. There are two types of motor: single motor and left and right double motor. According to the speed regulation mode, there are single speed, two speed and no section speed regulation.
  • the basic structure of the range hood consists of an electric motor, a vane (wheel), a casing, a oil tank, an oil collector, a light, and a multi-position key switch. Regardless of the type of range hood, the basic principle is to use a centrifugal multi-blade wind turbine to suck and drain soot.
  • the structure of the range hood mainly has the following problems:
  • Severe viscous oil All the fumes discharged from the range hood should pass through the multi-leaf wind wheel. If the soot is not effectively purified, the result is that the inner wall of the hood is polluted, resulting in a large amount of uneven oil accumulation in the fan impeller. It will gradually lose its balance, the suction effect will become worse and worse, and the mechanical noise will become larger and larger.
  • the main function of the range hood is to keep the kitchen clean, reduce environmental pollution and benefit human health.
  • the suction rate of the traditional range hood is about 70%. Due to the escape of the fumes, the indoor air quality is poor, which not only endangers the health of the family, but also the oil stains on the wall.
  • the soot filter is commonly used for fume. Separation, because only a small part of the oil can be filtered out, the purifying rate of the exhaust gas discharged outside is low, and the outdoor environment pollution is different.
  • the object of the present invention is to solve the above problems and provide a structural energy-saving and non-stick oil-absorbing range hood, which has the characteristics of "high efficiency, energy saving, non-stick fume, clean and environmental protection, convenient cleaning", etc., thereby realizing the indoor environment.
