At present, there are various brands and various types of range hoods on the market. So how can we choose a product with better performance and price? Experts suggest that consumers should pay special attention to the following points when purchasing:
1. Look at the logo This includes two aspects - the identification of the range hood and instructions for use. The name, trademark, rated voltage, rated input power and certification mark of the model, manufacturer or distributor should be marked on the range hood. If the range hood has an illumination bulb, the maximum power of the bulb used should also be indicated on or near the lamp holder. At the same time, each range hood is equipped with a Chinese instruction manual to help consumers use it safely. In the specification, the minimum distance between the range hood and the support surface of the cooking utensils on the stove should be marked, and the range hood should be prohibited from being directly baked.
2. Look at the structural design of the range hood should be easy to effectively remove the accumulated grease and dirt, and the surface of the casing should be as smooth as possible. Usually the range hood needs to be fixed on the wall, so in addition to the keys, holes, hooks, etc., it is required to have a suitable device to fix it on the wall.
3. Depending on the size of the kitchen and the amount of fumes, choose the right product. European-style range hood does not have a large capacity of the hood, suitable for modern kitchens with large space and not many fume; deep range hood and other styles Compared with the range hood, the utility model generally has the advantages of large air volume, and the structure of the large-capacity collecting hood is advantageous for sucking and discharging soot, and is suitable for kitchens with more soot and large space; the thin range hood is light and beautiful in appearance. The small footprint is suitable for small kitchens; the sub-deep range hood is between the thin and deep range hoods, suitable for kitchens with moderate space and smoke.
4. Select producers and operators with good after-sales service. Under normal circumstances, you should purchase famous brands of range hoods. These enterprises have high-quality service teams, advanced production technology and production capacity, which can not only produce better quality. The range hood products can also provide excellent after-sales service and relieve the worries of using the range hood.
5. The product should be selected according to its own consumption ability. It can be felt by hand to feel that there is no air leakage around the range hood. The air volume is not big. If there is no air leakage and the air volume is large, it indicates that the range hood has strong smoke absorption capacity; You can also directly feel the noise level of the range hood, especially the front noise, and touch the casing to see if it is vibrating. The quiet, stable running range hood is the user's first choice.
