The range hoods on the market are thin deep type and cabinet type cold type, among which the deep type range hood is a new generation product, which is the most popular and has occupied a dominant position in the market. This product has a beautiful appearance and, due to its structural advantages, the smoke exhaust rate can be matched with different styles of modern kitchen furniture. In order to enable you to buy a satisfactory deep-type range hood, the purchase points of this range hood are introduced as follows. The most important component of the motor and the main range hood is the motor.

At present, the domestic motor class can fully meet the design standard of the range hood. Therefore, when purchasing the range hood, there is no need to confuse the imported motor.

The bearing is also an important part of the range hood. The quality of the bearing should be related to the size and operating life of the sound.

When purchasing, you should choose a motor that uses a ball bearing. Such a motor has a long service life. It is necessary to use a full-gold fan blade. Such a blade is durable and stable in dynamic balance, which is more conducive to the separation of oil and smoke. At the same time, repeatedly press the hood motor switch to compare the running sound of the lower motor after starting and closing, the smaller the noise, the better.

Fans are not so good. Most hoods have a fan installed, but some hoods are designed with two fans. Is it better to have two fans than a fan? In fact, whether it is a fan or two fans, the exhaust gases are all in the same flue.

If the left and right fans are operated at the same time, although the two fans designed to rotate at the same speed, it is impossible to maintain complete operation during operation, so that the airflow discharged by the two fans has an opportunity to interfere and even increase the loss of the machine.

The suction size is checked. Suction is the most important function indicator of the range hood. The suction level is directly related to the smoking rate of the range hood. Suction is mainly determined by the size of the motor stalk of the hood. The greater the motor power, the greater the suction.

But it is not the best choice for the hood with the highest motor power. In fact, it should be based on the family and does not like to use large oil fires. Then, when cooking, it will not produce a lot of fumes, and the motor power is small. .

If you have no concept of professional technical indicators, and some brands do not specify specific technical parameters, then you can make some performances on your own when you purchase. For example, using a newspaper placed under the hood, and then turning on the machine, the suction will force the newspaper to be quickly attached to the hood. Almost all hoods can achieve this effect, which is not easy. Identify the size of the wind.

Since the amount of suction air volume is not clearly specified in the national standard, consumers can test it by a single method. The easiest way is to open the hood, open the hood, put your hand near the air inlet, feel the wind is down; put your hand at the air outlet and feel the wind; then put your hand on the seam of the hood , check, whether there is air leakage. The negative pressure generated by the range hood without the wind and the wind is concentrated, and the smoke exhausting effect is relatively good. It should be noted that the effect is not always the best, and the smoke venting machine with a balanced smoke exhausting rate is the largest.

Whether it is easy to clean the range hood is smoked and burned all the year round, it is difficult to contact, clean greasy and fume, easy to be contaminated by oil and dirt. The grease stain adheres to the machine surface, which not only affects, but also has a beautiful appearance, and has different effects on the normal operation and service life of the range hood. Therefore, the design of the hood itself is very important. At this point, all manufacturers have used a lot of thoughts. For example, the impeller surface is treated with a non-stick oil coating; the double oil passage design is adopted, and the inclined oil spill opening groove is added, so that the oil accumulated in the inner wall of the casing flows out of the slot, and the grease separated from the fan is separated by the oil. The holes flow into the oil cup together to prevent oil leakage; the body is elastically connected, which is easy to disassemble, easy to wash, etc. These are all reasonable designs.

From the fineness of the hood, the cold-rolled plate is made of cold-rolled plate, and the plastic-treated fully enclosed snail liner is such that the inner liner does not leak and does not leak oil, and is durable and rust-free.

The hood of the range hood should not have too many dead angle grooves, otherwise it will easily deposit grease, which is not easy and clean.

The hood ventilation tube should not be too long, and it is best to use the entire section of the duct to prevent smoke leakage.

Try to use mechanical switches, which are very durable, and electronic touch switches, such as poor design or poor materials, are easily contaminated, have a short life, and are not easy to repair after damage. In addition, the switch contacts should be made of silver or platinum, because they do not rust, and the electrical conductivity is good. , 28 household appliances 2, 1 year in 1
