Description
Technical field
The present invention relates to a kind of range hoods.
Background technology
Traditional range hood only has the function of suction oil smoke, and range hood unlatching can cause the negative pressure in kitchen, draw
It plays outdoor pollution air and kitchen is squeezed by crack between a door and its frame, window crack, so as to cause secondary pollution, also result in the smells such as sewer and fall
It fills and enters kitchen, deteriorate Air Quality in Kitchen.At the same time, kitchen range burning needs oxygen, and closed kitchen environment can lead to oxygen
Gas content is reduced, and reduces efficiency of combustion, if user selects windowing ventilation, equally faces the puzzlement that outdoor pollutant enters kitchen
And irregular air-flow upsets smoke absorption effect outside window.In addition, traditional range hood can not be realized after culinary art terminates
The function of purifying air in kitchen.
In order to overcome the drawbacks described above of existing range hood, there has been proposed in kitchen install fresh air system design,
As disclosed in the Chinese invention patent of Patent No. ZL 201410080381.9 (Authorization Notice No. is CN 103868187B)
《A kind of kitchen ventilation system based on air curtain and filtering》, which is made of fresh air section, air curtain section and exhaustion section.Fresh air section by
Fresh wind port, PM2.5 filters, pressure fan, ejector pipe mend the compositions such as wind branch pipe.Air curtain section is by reducer pipe, gas-cooker, angle adjustable
The compositions such as air curtain, hot air door blowpipe.Exhaustion section is made of exhaust hood, unidirectional stop valve, exhaust blower and exhaust outlet.Fresh air mistake
After filter, sent all the way to injector and mend wind branch pipe for needed for gas-cooker injection；It is sent all the way to for summer and transition season cooking
Air curtain；In addition it send all the way and adjusts air curtain temperature to hot air door blowpipe, meet human thermal comfort requirement.Air curtain jet stream and cigarette
Gas is expelled to outdoor by exhaust hood.Although the system can play it is heat-insulated, reduce indoor refrigeration duty, improve cooking comfort level and
Health degree prevents cooking oil smoke from sealing in bedroom parlor, improving the effects that system efficiency of combustion, is conducive to kitchen and makes open type,
But the fresh air system is mounted below hearth, is separately set with kitchen range and range hood, integrated level is poor, installs also more
Trouble.
In addition, the range hood that fresh air can be blown out inside range hood is also disclosed in the prior art, such as Patent No. ZL
Disclosed in the Chinese utility model patent of (201120448626.0 Authorization Notice No. is CN 202328439U)《One kind can be replaced
For the blower fan apparatus of kitchen ventilator》, which includes being arranged on air duct housing and wind turbine above environment-protection oven, wind turbine setting
