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...

AI Technical Summary

Problems solved by technology

However, the above-mentioned patents do not consider the formation of an upward airflow direction under the dominant action of the human body heat plume, kitchen hot airflow and smoke, and do not consider the need for supplementary air for the combustion of the gas stove, so it is necessary to design the overall ventilation system for the kitchen , to achieve a green, healthy, comfortable and efficient kitchen environment
