Nano-titanium-dioxide photocatalyst wind-curtain range hood

Abstract

The invention relates to a nano-titanium-dioxide photocatalyst wind-curtain range hood, comprising a range hood main machine. The range hood main machine is internally provided with an outer exhaust fan; the lower part and the top end of the range hood main machine are respectively provided with a smoke inlet and a smoke outlet; and an oil-smoke filtering net is arranged at the smoke inlet. The nano-titanium-dioxide photocatalyst wind-curtain range hood is characterized in that a nano-titanium-dioxide photocatalyst wind-curtain machine is arranged on the range hood main machine. The nano-titanium-dioxide photocatalyst wind-curtain range hood has the beneficial effects that on one hand, a large amount of oil-smoke mixed gas generated in a cookware and a pot surface is exhausted outside; on the other hand, the harmless gas purified by the wind-curtain machine meets the gas generated by the pot surface to form a wind curtain through facing to an operator; then the wind curtain forces the oil and the smoke generated by the cookware and the pot surface to be absorbed into the main machine instead of overflowing, simultaneously the harmless gas generated by a stove is separated from the air in a kitchen, and a large amount of pure air absorbed by the operator in a head-on manner is exhausted by the wind-curtain machine, so that the operator is greatly protected and the absorbing effect of the range hood main machine is enhanced.

Description

technical field [0001] The invention relates to the technical field of kitchen range hood manufacture, in particular to a nano-titanium dioxide photocatalyst air curtain range hood. technical background [0002] The kitchen is the source of life for thousands of households, and it is also the source of people's environmental pollution. A large amount of harmful gases are produced when people cook, as well as a large number of germs, viruses, and stench produced by sewers, public flues, rotten food, and food residues. The smell spreads over the whole kitchen, which greatly endangers people's health. Generally, range hood manufacturers simply increase the displacement of range hoods to solve the problem of eliminating kitchen pollution, but they cannot achieve a comprehensive and radical effect. [0003] Prior art such as the "clean circulating range hood with three-dimensional air curtain" of publication number CN1828148A, its main feature is to adopt the method of internal ...

[0004] There is another patent No. ZL200820056278.0 "Air Curtain Device for Side Suction Range Hood". This patent uses an activated carbon filter plate. Activated carbon uses porous physical properties to absorb macromolecular gases and suspended particles in the air (such as smoke, dust etc.), the purpose of filtering and purifying the air is achieved through the forced air circulation of the fan, but the filter element needs to be replaced regularly, the actual use efficiency is low, and the harmful gas cannot be eradicated
