Air supply terminal of breathing zone of kitchen

Abstract

The invention discloses an air supply terminal for a breathing zone of a kitchen. The air supply terminal comprises an air inlet, a hose and an air outlet device, wherein one end of the air inlet introduces fresh air from outside, and the other end of the air inlet is connected with the hose; the other end of the hose is communicated with the air outlet device; the hose is internally provided with a regulating valve which is used for regulating air quantity; and the upper part of the air outlet device is provided with an uneven pore plate, the middle part of the air outlet device is a pressure stabilizing section, the terminal of the pressure stabilizing section is provided with an even air outlet, and the even air outlet can be of a grid type or a gap type. According to the invention, the quantity of the fresh air is changed by regulating the aperture of the regulating valve, and the hose is twisted to change the direction of the air outlet, thus cooking environment is improved, oil smoke which enters into the breathing zone for a human body and is sucked by the human body can be greatly reduced, and air quality in the breathing zone for the human body is improved; and meanwhile, local thermal environment of the human body can be improved, and thermal comfort is improved.

Description

technical field [0001] The invention relates to a kitchen ventilation system, in particular to an air supply terminal of a kitchen breathing zone. Background technique [0002] At present, in residential kitchens, the smoke extraction efficiency of general kitchen exhaust hoods is only about 70%, and this is the maximum efficiency. Therefore, the remaining about 30% of the smoke rises with the cooking heat and spreads to other areas, some of which must be inhaled by the human body. In addition, some air curtain partitions may be used at the front end of the exhaust hood, but this cannot completely prevent the smoke from spreading to the human breathing area, and the air volume is large, and the energy consumption of the fan is high. [0003] In addition, the ventilation of the existing residential kitchen is a kind of unorganized air supply. The outdoor fresh air cannot be directly inhaled by the human body, but mixed with indoor polluted air and then inhaled by the human b...

AI Technical Summary

Problems solved by technology

In addition, some may adopt an air curtain partition at the front end of the exhaust hood, but this cannot completely prevent the smoke from diffusing to the human breathing area, and the air volume is large, and the energy consumption of the fan is high

[0003] In addition, the ventilation of the existing residential kitchen is a kind of unorganized air supply. The outdoor fresh air cannot be directly inhaled by the human body, but mixed with indoor polluted air and then inhaled by the human body.

[0004] To sum up, the traditional kitchen ventilation system cannot prevent cooking fumes from entering the breathing zone of the human body, and then being inhaled by the human body
