How to choose a range hood? Figure out these points, save money and don't step on the pit! ||Range hood is one of the must-have electrical appliances for new home decoration, how to identify misleading parameters to prevent being pitted? How to choose the right one for you? How to install it seamlessly? Super detailed purchase of pit avoidance nanny-level strategy, I hope to help you.
1. Motor. AC inverter "DC inverter, DC inverter has better overall performance, longer service life and more power saving.
Second, the efficiency of suction and exhaust fumes.
The air volume determines the smoking capacity of the range hood.
Conventional steaming and stir-frying: 20 22m min
Frying and stir-frying: 23m min and above.
The wind pressure determines the smoke exhaust and anti-fume backfill capacity.
Many people will confuse the wind pressure value with the static pressure value, the wind pressure value of the range hood when the air volume is 7m min.
The selection formula of wind pressure value: the total floor height of the building - the number of floors = the benchmark wind pressure value.
Difference 0 9: 260 310pa
Difference 10 19: 310 360pa
Difference 20 29: 360 400pa
Difference of 30 or more: 400 pa or more.
Preferably with variable frequency cruise, the wind pressure is intelligently adjusted according to the actual situation, which is more effective in preventing oil smoke backfill.
3. Clean and take care of it.
The internal cleaning of the range hood is not in place, and it is easy to increase the noise for a long time, reduce the smoke suction and exhaust power, and make it greasy and odorless. It is not cost-effective to find a professional to pay for cleaning on a regular basis, and it is preferable to have a self-cleaning function.
Common self-cleaning types.
Hot melt washing: There is a heating device on the impeller to heat and soften the oil. Heat-coagulation stains are not easy to clean and are prone to a smoky smell.
High-pressure direct spray cleaning: Install a high-pressure water pump, use it with detergent, and use water pressure to flush the oil on the turbine at high speed.
Steam washing: There is a heating device inside, which heats the water to form steam, and then sprays to dissolve and rinse the oil. High-temperature steam + porous nozzle with high-pressure washing can not only quickly and comprehensively dissolve the oil stain, but also disinfect and sterilize the internal environment of the range hood, with multiple protection, and the cleaning rate is 991%
No disassembly and cleaning: Filtering oil stains through a small dense mesh will affect the air volume and suction, and the cleaning effect cannot be guaranteed.
Fourth, intimate function.
Generally, there are smoke stove linkage, wave induction, intelligent cruise, automatic cruise pressurization, etc., which can be reasonably selected according to their own situation, and it is recommended to choose a smoke machine with frequency conversion function, and the noise is relatively smaller.
5. Noise. The national standard noise value of the range hood is <74db(a), and the business advertises that it is generally the sound pressure level value, but in fact, the sound power value is closer to the actual effect. Sound power value = sound pressure level value 14db, the smaller the value, the quieter it is.
Sixth, the degree of oil separation.
The higher the grease separation, the less oil stains will be attached to the range hood in the later use. The national standard grease separation degree is 80, you can choose above this value, if there is a high-temperature steam washing function, this value does not need to be too careful, it can meet the national standard.
7. Practical design.
Common smoke area design, intelligent cleaning reminder, quick release oil net, explosion-proof glass panel, lighting, etc.
