Embodiment Construction

[0019] The following provides a specific embodiment of a kitchen ventilation system based on negative pressure passive supplementary air and filtration of the present invention.

[0020] Passive wind capture and filtration: ① When cooking, first adjust the angle of the air curtain 9, and then turn on the exhaust fan 6. After the fresh air passes through the passive air supply outlet 1, it passes through the PM2.5 filter 2, and the large particles in the fresh air are filtered Drop and enter cabinet 11. Part of the fresh air in the cabinet provides the air needed for combustion and promotes complete combustion. Another part of fresh air enters the passive air curtain outlet 10 in the stove 8, and the jet flow of the air curtain, combustion waste gas and oil fume gas rise together under the effect of the human body heat plume, and enter the exhaust hood 7. The exhaust air passes through the check valve 4 and the elbow 11, and is discharged to the outside atmosphere through the ...

Abstract

The invention discloses a kitchen blowing and sucking type system based on passive air supplement. The system is composed of a fresh air section, an air curtain section and an exhaust section; the fresh air section is composed of a fresh air opening and a PM2.5 filter screen, the air curtain section is composed of an air supply opening, an angle-adjustable air curtain, a gas stove and a hot air curtain; the exhaust section is composed of an exhaust hood, a one-way stop valve, an exhaust fan and an exhaust outlet; fresh air passes through the fresh air opening, passes through the PM2.5 filter screen to form clean air, passes through the air supply opening and is supplied into a room from the air curtain; the air can be subjected to temperature adjustment through the hot air curtain to meetthe human body thermal comfort requirement; and flue gas and lampblack are exhausted outdoors through the exhaust hood. According to the kitchen blowing and sucking type system, harmful flue gas can be discharged outdoors, the harmful flue gas is prevented from entering a room, the air curtain supplies air to improve the indoor air quality, the heat comfort degree of a human body is improved, andthe combustion efficiency of the gas stove is improved.

Description

technical field [0001] The invention relates to a kitchen ventilation system based on negative pressure passive air supplement and filtration, which is a comprehensive kitchen ventilation system integrating oil fume restriction, oil fume removal, and fresh air supplement air. The invention belongs to the field of HVAC, pollutant control and gas combustion. Background technique [0002] With the advancement of urbanization, the daily life style of ordinary people has undergone tremendous changes. Residential buildings show intensive and intensive characteristics, and high-rise residential buildings appear. The dense living environment makes people put forward higher requirements for health and thermal comfort, and the demand for air quality is also getting higher and higher. [0003] The use of gas stoves in residential kitchens consumes oxygen, produces exhaust gases such as carbon dioxide, and produces oil fumes. These exhaust gases and fumes are discharged outside throu...
