It's quite good. When the Royalstar range hood works, it consumes less electricity.

range hood

, also known as range hood, is a kind of kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove, which can quickly pump away the waste burned by the stove and the oil fume harmful to human body generated in the cooking process, and at the same time, condense and collect the oil fume, reduce pollution, purify the air, and have anti-virus and anti-explosion safety guarantee functions.

range hoods need to be cleaned regularly, and simple cleaning can't get rid of oil stains. To clean range hoods, professional cleaning agents must be used.

background

in the early days, smoke exhaust in family kitchens was done by exhaust fans. Although the exhaust fan can remove most of the oil fume in the kitchen, it is unable to solve the pollution of the oil fume produced in cooking to the whole kitchen. The oil fume produced in cooking contains many substances harmful to human body. If people work in a room full of oil fume for a long time, it will lead to many diseases.

according to the research report of who, among the 4.3 million people who died of air pollution in the kitchen in 2112, 34% suffered from stroke, 22% from chronic obstructive pulmonary disease and 26% from ischemic heart disease, and about 6% died from lung cancer.

In a research project on disease risk assessment published in The Lancet, a famous British medical journal, kitchen air pollution (smoke) has been listed as the biggest health hazard after hypertension, smoking and alcoholism. Every year, the number of people who die from continuous inhalation of smoke from kitchen fires is more than the total number of deaths caused by malaria, tuberculosis and AIDS.

The research on farmers in China in the Journal of the National Cancer Society in the United States also confirmed the impact of air pollution in the kitchen on people's health. Scientists from China and the United States who participated in the study surveyed more than 21,111 farmers in Yunnan Province and found that the probability of lung cancer of farmers who had no ventilation in their stoves was about twice that of those who had added chimneys or ventilation in their homes.

The researchers say that using a stove without ventilation is similar to smoking to the extent of causing lung cancer.

China people's dietary structure is different from that of westerners, so the variety, style and arrangement of kitchen utensils are quite different from those of western countries.

China is a country that pays attention to delicacies. In food processing, frying, frying, cooking and frying account for a large proportion, so there is a lot of oil smoke in Chinese kitchens, which makes the kitchen environment greasy and difficult to clean. Therefore, the range hood has become a necessary machine to change the kitchen environment. It changes the kitchen environment and reduces the harm of oil fume to the kitchen environment and human health.

the first range hood in China was introduced by the people's Republic of China and the Ministry of Commerce in Munich, Germany. At that time, the technology and product appearance were introduced.

But it is not produced in combination with China people's own cooking methods. Foreign family cooking mainly emphasizes maintaining the nutrition and original flavor of vegetables, and basically using cooking and frying cooking skills will not produce much oil smoke. And China people emphasize that strong fire and stir-fry will produce a lot of oil smoke. The smoking machine is designed by using the principle of rising hot air. Filter the oil fume through the oil net, but it does not reach 111%.
