Definitions

  • the invention relates to a range hood.
  • Range hoods are widely used nowadays.
  • problems with the conventional range hoods first, large amount of oil remains on fans thereof after long-time use, which affects oil suction and brings about large noise; second, they are low-efficient and power consuming; and third, their operation contaminates indoor and outdoor environment; and finally, cleaning thereof cost users a lot.
  • a range hood comprising a fan having a housing and an impeller, an oil filter, a cover, a fume exhaust cover, a light, and a switch.
  • the housing of the fan is a circular double-chamber or multi-chamber structure with an air inlet and an air outlet, and the impeller of the fan comprises at least one group of arc-shaped blades each having a closed side and being enlarged in an axial direction.
  • the housing of the fan comprises a swirl chamber and an impeller chamber.
  • the impeller is disposed in the impeller chamber.
  • a motor is disposed at the top of the housing.
  • the impeller is connected to the motor.
  • the air inlet is disposed at the bottom of the swirl chamber, and the air outlet is disposed on the right of the swirl chamber.
  • a blade of the impeller is disposed on an impeller disk, and the impeller disk is connected to a motor shaft of the motor, and a seal sheet is disposed in the front of the impeller disk.
  • the oil filter comprises a support, a first oil screen, a second oil screen, and an oil tray.
  • the first oil screen is fit on the support
  • the second oil screen is disposed at the top of the support
  • the oil tray is connected to the bottom of the support.
  • the first oil screen and the second oil screen are made of soft materials, and the oil tray is made of hard materials such as plastics or metal plates.
  • the oil filter is in the shape of a frustum.
  • three sides of the fume exhaust cover are closed.
  • the fume exhaust cover comprises a metal frame, a metal plate, and a glass plate, the metal plate operates to seal a lower part of the metal frame, and the glass plate operates to seal an upper part of the metal frame.
  • the impeller, the blade, and the housing cause gas not to be collided with the impeller or the housing, oil smoke does not pass the impeller, and thus volume loss, flow loss and power consumption are significantly reduced, and work life of the impeller is increased; on the other hand, the arc-shaped blade having a closed side is disposed in the double-chamber structure of the housing and forms a swirling flow field that quickly rotates with respect to the shaft whereby reinforcing convergence.
  • the swirling flow field transmits gas in a manner of “driving gas via gas” instead of using a rotating impeller or a blade, and thus a new power transmission mode—a swirling flow field mode is formed. Oil is not attached to the range hood, which ensures cleaning of the impeller without disassembling, and the invention features high efficiency, low power consumption and noise, few consumables, easy production, and long work life.
  • oil smoke is filtered for two times via the first oil screen and the second oil screen, and thus complete separation between oil and smoke is implemented, which significantly improves purification rate of oil and smoke, ensures cleaning in the range hood, and prevents outdoor environment pollution.
  • the first oil screen and the second oil screen are made of soft materials that are convenient to be cleaned or replaced, which reduces maintenance cost.
  • the fume exhaust cover having three closed sides can completely cover the oil smoke and prevent it from dissipating, which improves suction efficiency, and ensures freshness of indoor air and cleaning of walls.
  • the invention increases suction efficiency by above 10% and reduces power consumption by above 10%, noise thereof is ⁇ 50 dB, suction rate of oil smoke is above 95%, purification rate of oil smoke is above 90%, and a work life thereof is three times longer than the conventional range hood.
  • the invention features high efficient, low power consumption and no attached oil, is cleaning and environment-friendly, and is convenient for cleaning.
  • Technical and economic index of the invention reach the top level in the world, energy saving and emission reduction effect caused thereby is significant, and economic and social benefit is remarkable.
