Abstract: Range hoods have now become one of the indispensable household appliances in modern households. By comparing the difference between the national standard and the IEC standard test method for the air volume of range hoods through tests. It is found that due to the limitation of the public flue, the excessive air volume of ordinary residences not only cannot exert a better smoke exhaust effect, but also affects the cooking time. The flow direction of the generated oil fume is disturbed. There are some differences between the national standard and the IEC standard for the test method of the air volume of the range hood. When the range hood products are exported to Europe, it is necessary to pay attention to the difference in the product performance standards, and also provide a reference for the subsequent formulation of the standard test method.
