Fresh air assembly of range hood and fresh air range hood

Abstract

The invention belongs to the technical field of range hoods, and discloses a range hood fresh air assembly and a fresh air range hood. The range hood fresh air assembly comprises an air inlet assembly and an air outlet assembly, and the air inlet assembly is used for introducing air outside a kitchen into the kitchen; the air outlet assembly is installed on the range hood, communicates with the air inlet assembly and is used for compressing and blowing out the air outside the kitchen conveyed by the air inlet assembly to form an air curtain, and the blowing-out angle of the air curtain is adjustable. According to the range hood fresh air assembly, air outside a kitchen can be compressed and blown out to form an air curtain with the adjustable blowing-out angle, the air temperature in the kitchen can be reduced, rising oil smoke can be pressed in the cooking process, dissipation of the oil smoke in the kitchen is reduced, the oil smoke is prevented from rising and flying on the face of a user, and the use feeling of the user is improved. The range hood fresh air assembly is used in the fresh air range hood, a large amount of clean air can be supplemented into a kitchen, meanwhile, the negative pressure environment in the kitchen can be improved, the smoke exhaust efficiency of the range hood can be improved, dissipation of oil smoke can be effectively suppressed, the pollution problem in the kitchen is solved, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a hood fresh air assembly and a fresh air hood. Background technique [0002] The fresh air hood is a new type of integrated range hood, which integrates the hood and the fresh air component. The fresh air component can deliver air to the hood in the lampblack environment, which is used to supplement the air in the kitchen and reduce the indoor negative pressure. The impact on the hood is conducive to improving the air quality in the kitchen and reducing the pollution of oil fume to the kitchen. [0003] However, the existing fresh air unit can only realize the internal circulation of the kitchen air, that is, the fresh air component absorbs and purifies the kitchen air and then blows the kitchen air out again to realize the internal circulation of the kitchen air. However, since the fresh air component can only perform internal circulation, a large amount of air is absorbed...

AI Technical Summary

Problems solved by technology

However, since the fresh air component can only perform internal circulation, a large amount of air is absorbed and discharged by the hood during the cooking process, resulting in a limited effect of the fresh air component, which can absorb and purify very little air, and it is difficult to play the role of purifying and replenishing air; moreover , due to the harsh environment of cooking fume in the kitchen, the fresh air module directly absorbs and filters the air in the kitchen, and the oil will quickly block the filter element and cause its purification failure. The effect of air pressure in the kitchen, the function is single, and the practicability is poor
