Description
Technical Field

Meanwhile, oxygen is needed for the combustion of the kitchen range, the oxygen content of the closed kitchen environment can be reduced, the combustion efficiency is reduced, and if a user selects windowing ventilation, the trouble that outdoor pollutants enter the kitchen and irregular airflow outside the window disturb the oil smoke absorbing effect are also faced. In addition, the conventional range hood cannot realize a function of purifying kitchen air after cooking is finished.
In order to overcome the above-mentioned drawbacks of the existing range hood, a design of installing a fresh air system in a kitchen has been proposed, such as "a kitchen ventilation system based on air curtain and filtration" disclosed in chinese patent No. ZL 201410080381.9 (issued patent No. CN 103868187B), which is composed of a fresh air section, an air curtain section and an exhaust section. The fresh air section consists of a fresh air port, a PM2.5 filter, a blower, an injection pipe air supplementing branch pipe and the like. The air curtain section consists of a reducer pipe, a gas stove, an angle-adjustable air curtain, a hot air curtain air supply branch pipe and the like. The exhaust section consists of an exhaust hood, a one-way stop valve, an exhaust fan and an exhaust outlet. After the fresh air is filtered, one path of fresh air is sent to an ejector air supplementing branch pipe for ejection of the gas stove; one path is sent to an air curtain for cooking in summer and transitional seasons; the other path is sent to the hot air curtain air supply branch pipe to adjust the temperature of the air curtain, thereby meeting the thermal comfort requirement of human body. The air curtain jet flow and the flue gas are discharged outdoors through the exhaust hood. Although, this system can play thermal-insulated, reduce indoor cold load, improve cooking comfort level and health degree, prevent that cooking oil smoke from cluster entering bedroom living room, improve the effect such as system combustion efficiency, be favorable to the kitchen to make open-type, but this new trend system installs in the top of a kitchen range below, equally divide the body setting with cooking utensils and range hood, and the integrated level is relatively poor, and the installation is also comparatively troublesome.
In addition, there is also disclosed a range hood capable of blowing fresh air inside the range hood in the prior art, such as the fan device capable of replacing the range hood disclosed in chinese patent No. ZL 201120448626.0 (issued patent No. CN 202328439U), which includes an air duct housing disposed above the environmental protection stove and a fan disposed on a side surface of the air duct housing, wherein an annular partition plate is disposed in the air duct housing, the air duct housing is partitioned into a fresh air duct and a converging flue by the annular partition plate, an air outlet of the fresh air duct is disposed at a lower portion of the air duct housing, and an opening of the air outlet faces the smoke exhaust pipe. When the fan device works, the fresh air blown out from the air outlet directly blows the oil smoke to the smoke exhaust pipe, the wind resistance is very small, and the electric energy is greatly saved. Therefore, the fresh air fan of the fan device is used for blowing the oil smoke to the smoke exhaust pipe in an accelerating way, and although the oil smoke exhaust effect is improved, fresh and clean fresh air cannot be conveyed to a kitchen, and the combustion efficiency of a kitchen range cannot be improved.

The purified oil smoke gas is mixed with fresh air, and then passes through the primary filter screen 16, the electrostatic purifying unit 15 and the high-efficiency filter screen 17 in sequence to form clean air, and the clean air is sent into a kitchen from the fresh air outlet 6.
2) After cooking, in order to quickly purify kitchen air, the first one-way valve 9 is opened, the second one-way valve 12 is opened, the fresh air fan 8 runs at a low speed and with low noise, the third one-way valve 18 is opened, and the range hood fan 4 runs at a low speed and with low noise. An airflow passage is formed between the fresh air outlet 6 and the air inlet 10, so that air above the kitchen is purified; an airflow passage is formed between the fresh air outlet 6 and the air inlet of the range hood, so that air below the kitchen is purified.
3) In other time periods, the range hood intelligently detects the air quality and the oxygen content of the kitchen, if the air quality and the oxygen content are lower than the set values, the first one-way valve 9 is opened, the second one-way valve 12 is closed, the third one-way valve 18 is opened or closed, the fresh air fan 8 runs at a low speed and with low noise, and fresh clean air is fed into the kitchen through the fresh air outlet 6. If the outdoor air temperature is unfavorable or pollution is serious, the first one-way valve 9 is closed, the second one-way valve 12 is opened, the indoor circulation mode of the fresh air system is entered, and the kitchen air is circulated and purified through the fresh air purifying device 14.
Therefore, the lampblack of the range hood can not be discharged to the outdoor or public flue, and the zero-emission environment-friendly range hood is formed.
