Description

A kind of range hood
Technical field
It the utility model is related to a kind of range hood.
Background technology
Traditional range hood only has the function of suction oil smoke, and range hood is opened the negative pressure that can be caused in kitchen, drawn Play outdoor pollution air and kitchen is squeezed into 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 Filling enters kitchen, deteriorates Air Quality in Kitchen.At the same time, kitchen range burning needs oxygen, and closed kitchen environment can cause 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 composition such as wind branch pipe.Air curtain section is by reducer pipe, gas-cooker, angle adjustable Air curtain, hot air door blowpipe etc. form.Exhaustion section is made of exhaust hood, unidirectional stop valve, exhaust blower and exhaust outlet.Fresh air mistake After filter, send all the way to injector and mend wind branch pipe for needed for gas-cooker injection;Send all the way to for summer and transition season cooking Air curtain;In addition send all the way to hot air door blowpipe to adjust air curtain temperature, 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, prevent cooking oil smoke from sealing in bedroom parlor, improving the effect such as system efficiency of combustion, is conducive to kitchen and makes open type, But the fresh air system is installed on 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 passage housing and wind turbine above environment-protection oven, and wind turbine is set The side of housing in air passage, is provided with annular partition in the housing of air passage, annular partition by air passage housing be separated into fresh air pipeline and Converge flue, and the air outlet of fresh air pipeline is arranged on the lower part of air passage housing, and the opening of air outlet is towards smoke exhaust pipe.The wind turbine fills When putting work, oil smoke is directly blowed to smoke exhaust pipe by the fresh air of air outlet blowout, and windage is very small, greatlys save electric energy.Thus As it can be seen that the fresh-air fan of the blower fan apparatus is for accelerating oil smoke to blow to smoke exhaust pipe, although being conducive to improve smoke absorption effect, But the fresh air of fresh clean cannot be conveyed to kitchen.
