With the improvement of people's living standards, cooking in the kitchen is not full of fumes, which is inseparable from the credit of the range hood. We don't want to be battered with oily smoke, we need a good range hood, let Xiaobian take everyone to look at the range hood, hope to help you choose a good range hood .
How to choose a range hood
1, exhaust air volume
This is one of the main quality indicators of range hoods. If the exhaust air volume is large, the generated soot gas will not overflow the cover, and most of it will be sucked into the hood and discharged to the outside through the exhaust duct. But the amount of exhaust air is not as big as possible. If the exhaust air volume is too large, it will take away too much heat and affect the normal calorific value of the stove fuel. National regulations stipulate that the exhaust air volume should be greater than 6cm3/min. Of course, the current range hood products on the market have basically reached the level of 14m3 / min, Whirlpool's products have reached a large exhaust volume of 17-20m3 / min.
2, exhaust efficiency
Exhaust efficiency is the percentage of the amount of fouling that is removed from the hood and the amount of smog that is generated during the cooking process. The state is determined by measuring the content of carbon monoxide. According to the standard, the efficiency of exhaust should be greater than 60%. The above two items can be read at the time of purchase. If the instructions are not indicated, it is best to choose another one.
3, noise
Noise is also an important indicator of the performance of range hoods. In foreign countries, the noise of the range hood is controlled at 3050 decibels. Most of the countries use multi-blade centrifugal fans, the speed is relatively high, and the corresponding noise is also large. Therefore, the specification stipulates that the noise cannot exceed 70 decibels. At the time of purchase, you can judge by pressing the test.
4, oil filter device
After the range hood has been used for a period of time, the suction surface will be blocked by oil and sometimes it will drip off the oil. Therefore, oil filtering devices are generally provided. There are several types of oil filtering devices: single or double wire mesh, which can be removed and cleaned regularly before being installed in the suction port; labyrinth filter, which uses the principle of collision to filter soot, can be periodically removed and cleaned, and the filtering effect is better than before. It is good to use; after the oil is removed by the centrifugal action of the fan, it flows into the oil cup along the oil tank, and can be poured out periodically. This is practical and the number of cleaning is small.
5, the number of hood eyes (the number of suction ports)
Range hoods on the market are available in both single and double eyes. There is a motor and fan in the monocular machine, and an air inlet. The binocular machine is two motors and fans with two air inlets. It can be selected according to the condition of the stove at home. If you use a coal stove or a one-eye gas stove at home, you should buy a single-eye range hood; if you use a binocular gas stove for home use, it is best to buy a binocular range hood. When the two stoves are used at the same time, the two fans can be turned on at the same time, and the exhaust efficiency is high. When you don't need to open both sides at the same time, you can use only one side, which is convenient and practical. But the price of a binocular range hood is more expensive than a single eye.
Pay attention to the following points when purchasing a range hood
1, the amount of wind. Try to choose a range hood with a large air volume. In addition, the amount of wind is not how big it is to design, it is subject to many factors. At present, the air hood of the market can reach 14m3/min, which is already very good.
2, wind pressure. Wind pressure refers to the static pressure value when the wind hood of the range hood is 7m3/min. The larger the wind pressure value, the better. Similarly, wind pressure is subject to many factors, as is the wind.
3. Noise. Noise is also an important technical indicator to measure the performance of range hoods. The state stipulates that the value of this indicator is not more than 74dB.
4. Motor input power. The input power of the 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 not used. Second, the higher the power, the more the noise may be. fee.
5. Choose stainless steel, preferably 304 stainless steel. The benefits are not rusting and easy to clean.
6. When choosing a range hood, look at his effect of sucking smoke, that is, whether the air inlet at the oil net is large enough, because the suction is the same as the running water, but the pipe is thin and the smoke exhausting effect is not good.
7. Look at the oil filter effect of his oil net. A good oil filter effect will make the life of the hood motor longer.
8. See if there is a big gap, the big gap will be ash, not clean.
9. Does the appearance match your decoration style?
