Range hood with personalized air purifier

Abstract

The invention discloses a range hood with a personalized air purifier. The range hood comprises a shell and a control system. A self-balance type air inlet is formed in the front side of a top plate of the shell. A double-layer shutter air supply outlet is formed in a front face plate of the shell. A controller and a PM2.5 mass concentration sensor are installed on the front face plate of the shell. In the flowing direction, from the top of a kitchen to a human body breathing area, of primary air, a combined multilayer filter and a silent cross-flow fan are sequentially installed in the air purifier, and an air outlet is formed in the exhaust direction of the silent cross-flow fan. Due to the adoption of the device, it is ensured that the fan is stable and low in noise in the running environment, detection and overall control of the air quality in a human body head breathing area are achieved, harm of cooking fume particles and gas to human bodies is reduced, and meanwhile overflow of the cooking fume can be reduced through a lateral lower air supply curtain.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with a personalized air purifier. Background technique [0002] As the largest source of indoor air pollution, the health hazards of cooking fume to human body has received more and more attention and attention. In urban households, gas fuels such as coal gas, natural gas, and liquefied petroleum gas are mostly used for cooking activities. In the process of cooking food, cooking oil, raw materials and seasonings will produce a large amount of soot gas. Oil fume can be divided into two parts: oil mist and gaseous pollutants according to the different forms. Oil mist is a mixture of liquid and solid total suspended particle pollutants. The particle size is mainly aerosol particles below 100 microns. This part of pollutants will be suspended in the kitchen air, including PM10, PM2.5, PM1 etc. Gaseous pollutants mainly include volatile organic compounds (VOCs), gaseous semi-volatile o...

AI Technical Summary

Problems solved by technology

This design has the following disadvantages: 1) The product is too large to be arranged in the current narrow kitchen space; 2) The product does not take into account the influence of the air purifier airflow organization on the kitchen exhaust system; 3) The product does not have Considering that the purified air will be mixed with soot gas to cause secondary pollution when it is sent to the human breathing area

Although the air purifier can effectively capture the soot gas suspended in the air, it cannot effectively improve the air quality in the breathing zone of the human body
