Economic Daily - China Economic Net Beijing August 14th The market has a wide range of brands and various types of range hoods, what indicators do consumers need to care about when purchasing range hoods? On the 10th, Jiangsu Provincial Quality Supervision Bureau released Household range hood product supervision and spot check report. Spot check shows that the detection rate of unqualified products of range hood is 32.3%, Zhongshan Blake Electric Co., Ltd., Foshan Shunde Zhile Electric Co., Ltd., Zhongshan Jiulong Electric Co., Ltd., Zhongshan Weikai Electric Co., Ltd., Foshan Shunde Zuntai Electric Co., Ltd., Zhongshan Chaoshun Electric Co., Ltd., Guangdong Shunde District Yingman Electric Co., Ltd., Zhongshan Zhongfeng Fengfan Hardware Appliance Co., Ltd., Zhongshan Wantian Life Appliance Co., Ltd. The company, Zhongshan Xinbang Electric Co., Ltd., Zhongshan Qiaotai Taiwei Kitchen Appliance Co., Ltd. and other products were found to be unqualified.
In this batch, 34 batches of range hoods were tested, and 11 batches were unqualified. The failure rate was 32.3%. The spot check found that the 10 batches of products had failed the full pressure efficiency project. The project reflected the ability of the range hood to effectively utilize the motor power; The measured wind pressure value of the 7 batch product wind pressure project is lower than the standard value or the enterprise explicit value. The wind pressure index is the ability to assess the anti-downwind of the range hood. The exhaust pipe is longer or the public flue is needed. Wind pressure can discharge the flue gas; 5 batches of products in the highest-grade operation, the noise generated exceeds the standard limit and the company's explicit value; 5 batches of measured air volume values do not meet the standard requirements.
Consumers should choose the type of range hood according to the installation space and install it above the gas stove. The minimum distance between the support surface of the cooking appliance and the lowest part of the range hood should be 65cm. Note the air volume and wind pressure of different brands of range hoods. Value, in the case that other indicators meet the requirements, in theory, the higher the two values, the better the air performance of the range hood. The noise index of the range hood should also be paid attention to when purchasing.
Do not shut down immediately after cooking. After the cooking is finished for five or six minutes, then turn off the range hood, which can effectively discharge the harmful gases left in the kitchen to the maximum extent.
