Air purifier for home kitchen

Abstract

The invention provides an air purifier for a home kitchen. The air purifier comprises a shell with an air inlet in the front end and an air outlet in the rear end. A filtering channel is formed in the shell. A draught fan is arranged in the filtering channel. The air purifier is characterized in that a former filtering device for filtering out large-grain-size particles and a later filtering device for filtering out small-grain-size particles are arranged in the filtering channel, and a rotary filter screen for blocking and filtering out oily particles is arranged in the filtering channel. The air purifier has the beneficial effects that the air purifier for the home kitchen is designed for the air environment of the home kitchen, and the air purifier can keep working normally under the condition that lampblack is sucked continuously; the residual lampblack, burnt gas and peculiar smell in kitchen air can be effectively removed, viruses and bacteria in the air are killed, and therefore the air quality of the home kitchen is remarkably improved; and the lampblack particles are removed in a classified manner from the coarse particles to the fine particles, the service life of all the parts is greatly prolonged, and the requirements for the purification performance are met after all the parts are integrated.

Description

technical field [0001] The invention relates to an air cleaning device, in particular to a family kitchen air cleaner. Background technique [0002] During the cooking process, edible oil will form a mixture of gaseous, liquid and solid organic matter forms under high temperature conditions, that is, soot. According to different forms, the mixture of liquid particles and solid particles is called oil mist, and these particles are divided into settleable particles and inhalable particles; the gaseous part is volatile organic compounds (VOCs), and the gaseous pollutants in the home kitchen are also There is combustion exhaust. The particle size of the settleable particles in the oil fume is mainly distributed between 10-400um. These particles will settle to the ground and the surface of other utensils due to the action of their own gravity and the interaction between particles, and will not cause lasting damage to the kitchen air environment. sexual pollution. Generally, pa...

Problems solved by technology

In addition, for the photolysis link of general air purifiers, its catalytic layer is very afraid of oil. If the oil cannot be removed through the previous steps of photolysis, the catalytic layer will be covered by oil pollution and photolysis will lose its effect.

Therefore, for general air purifiers, if you want to use them in the kitchen air environment, the above problems are unavoidable. The service life of the air purifier will be greatly shortened due to the particularity of the use environment, and its normal use will be seriously affected. and restrictions, and after a short period of use, it can itself become a source of pollution
