Kitchen ventilation system based on air curtain and filtration

Abstract

The invention discloses a kitchen ventilation system based on an air curtain and filtration. The system consists of a fresh air section, an air curtain section and an air exhaust section, wherein the fresh air section consists of a fresh air port, a PM2.5 filter, an air feeder, an injector air-supplement branch pipe and the like; the air curtain section consists of a reducing pipe, a gas stove, an angle-adjustable air curtain, a hot air curtain blowing-in branch pipe and the like; the air exhaust section consists of an exhaust hood, a one-way check valve, an exhaust fan and an air outlet; after being filtered, one path of fresh air is conveyed to the injector air-supplement branch pipe so as to be used for injection of the gas stove, one path of fresh air is conveyed to the air curtain for cooking in summer and transitional seasons, and another path of fresh air is conveyed to the hot air curtain blowing-in branch pipe so as to regulate the temperature of the air curtain and meet the heat comfort requirement of a human body; the jet current and fume of the air curtain are discharged to the outdoors by virtue of the exhaust hood. The system can be used for achieving the effects of insulating heat, reducing indoor cooling load, improving the cooking comfort degree and health degree, preventing cooking fumes from spreading into a horizontal living room, improving the combustion efficiency of the system and the like, is beneficial to formation of an open kitchen and ensures that the architectural space is fully utilized.

Description

technical field

[0001] This patent proposes a kitchen ventilation system combining air curtain and fresh air filtration, especially a comprehensive system of kitchen fresh air filtration, supplementary air, exhaust and air curtain protection, which belongs to the fields of HVAC, pollution control and gas combustion. Background technique

[0002] With the advancement of urbanization, people's lifestyles are changing. Residential housing presents a variety of forms such as low-rise residences, multi-storey residences, mid-high-rise residences and high-rise residences. Nowadays, people have higher and higher requirements for health, environmental protection and thermal comfort, and people have paid attention to the indoor air quality of the kitchen in the house.

[0003] Gas stoves are used in the kitchen to consume gas and oxygen, and waste gas is produced after combustion. At the same time, different cooking methods will produce different aerosol pollutants, which are discha...

Examples

Embodiment Construction

[0018] Such as figure 1 and figure 2 , when cooking in summer and the transitional season, the adjustable angle air curtain 8 is opened at first, and the high-efficiency axial flow blower fan 3 and the blower fan 12 are opened, and the air valve 15 is opened, and the air valve 18 is closed. After the fresh air passes through the fresh air inlet 1, it passes through the PM2.5 filter 2 to filter out large particles in the fresh air. Then enter the air supply main pipe 5 through the elbow 4. A part of the fresh air enters the cabinet space at the lower part of the gas stove through the injector supplementary air branch pipe 14, the air valve 15 and the supplementary air outlet 16, and provides the ejector with the air required for combustion, so as to promote sufficient combustion and avoid the exhaust of the ejector. clogged with particulate matter. Wherein another part of the fresh air is sent into the angle-adjustable air curtain 8 of the gas stove 7 through the reducing p...
