First, the household range hood purchase indicators
1, the hood air volume
The air volume refers to the amount of exhaust air per unit time of the range hood when the static pressure is zero. The state stipulates that the indicator value is greater than or equal to 7m3/min. Generally speaking, the larger the air volume value, the more quickly and timely the suction and discharge of a large amount of oil smoke in the kitchen. When other indicators are good, try to select a range hood with a large air volume value.
2, hood wind pressure
Wind pressure refers to the static pressure value when the air volume of the range hood is 7m3/min. The national standard specifies that the index value is greater than or equal to 80Pa. Wind pressure is also an important indicator to measure the performance of the range hood. The greater the wind pressure value, the stronger the anti-winding ability of the range hood. If the exhaust pipe is long or connected to the public flue, the exhaust pressure is greatly lost. More wind pressure is needed to ensure that the smoke is exhausted. Therefore, when other indicators are good, the greater the wind pressure value, the better.
3, hood noise
Noise is also an important technical indicator to measure the performance of the range hood. It refers to the A sound power level measured by the specified method when the range hood is operated at the highest speed and rated frequency. The national standard is not more than 74dB. .
4, range hood input power
The model of the range hood is generally specified as CXW-□-□, where the number in the first “□†indicates the input power of the main motor. The input power of the household range hood is not as large as possible, because the power is increased to increase the air volume and wind pressure. If the air volume and wind pressure are not improved, the power is increased and the power is increased. Electricity.
Second, home range hood purchase skills
1. Pick the brand: In comparison, the quality of the famous brand's range hood is guaranteed, and the after-sales service is also quite thoughtful.
2, choose the classic: Do not blindly pursue new products, try to buy classic models with large sales, mature models will bring you peace of mind. For example, the touch switch, although beautiful, is often expensive and easy to break, while the mechanical switch has a low maintenance rate and is highly replaceable, and can be repaired if it is broken.
3. Type of selection: The type of household range hood is selected according to the size of the kitchen and the amount of soot. European style is the choice of families who don't often cook. People who love Chinese food culture should consider deep-cover type range hoods.
4, than the accessories: the quality of the motor of the household range hood directly affects the effect and noise of the range smog, the quality of the bearing is directly related to the life of the range hood and the size of the noise, the metal texture of the impeller is more durable and can be more effective Noise reduction, better performance in soot separation, glass and stainless steel panels to scrub and save effort.
5, inspection products: the hood of the hood should be as few joints and grooves as possible, leaving no room for dirt and dirt. You can ask to start listening to the noise, and feel the air around you. If you have any doubts in your heart, you should ask the shopping guide in time. The more vocal the answer is, the more you have to ask.
6, look at the service: Range hoods deal with soot every day, sooner or later to clean, so can not just look at the eyes, but also plan long-term. What are the after-sales services? Is the free project life-long or free during the warranty period? What are the procedures and costs of maintenance? The verbal commitment is the least credible, and the black and white letters are the most reliable in the terms of service.
