Description

Spray purification environmental range hood

technical field

The utility model relates to the field of kitchen equipment, in particular to a range hood.

Background technique

The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the healthy and energy-saving range hood stove in the kitchen. It can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have anti-virus and explosion-proof safety guarantees. effect. Range hoods have not been in the kitchen of ordinary Chinese families for a long time. Early home kitchen smoke exhaust work was done by exhaust fans. Although the exhaust fan can get rid of most of the oily fumes in the kitchen, it is unable to solve the pollution of the entire kitchen by the oily fumes generated during cooking. The cooking fume contains many substances harmful to the human body. If people work in a room full of fumes for a long time, it will cause many diseases.

For the Chinese, the dietary structure of Chinese people is different from that of Westerners, so the variety, style and arrangement of kitchen utensils in the kitchen are very different from those of Western countries. In Chinese food processing, frying, frying, cooking , frying occupies a large proportion, resulting in a lot of oil fume in the Chinese kitchen, and it is easy to make the kitchen environment greasy and difficult to clean. Therefore, the range hood has become a "powerful weapon" to change the kitchen environment. It changes the kitchen environment and reduces the damage caused by oil fume to the kitchen environment and human health. Range hood can be described as the "killer" of oil fume.

The oil fume of the existing range hood is directly discharged into the atmosphere by the flue through the exhaust pipe after being inhaled by the wind wheel, and this type of range hood cannot be used in some places where environmental protection is required.
