[PConline Professional Review] The National Day holiday is a time of reunion with family members to make a sumptuous meal. Refreshing cold dishes, healthy hot drinks, stir-fried seafood and other banquet friends and relatives. Don't let fumes from the kitchen become a burden for your family and family to enjoy the happiness and food. Smoke contains a variety of harmful substances, including acrolein, benzene, formaldehyde, crotonaldehyde and other toxic carcinogens. A powerful range hood is the most important. When the fire is turned on, the range hood is turned on, and after the cooking is completed, it is continued for a while and then closed, leaving no trace of a taste.
The importance of having a range hood at home is very obvious, but not all range hoods are suitable for Chinese families. People like to stir fry, it will produce a strong smell of oil, you need to use a more efficient range hood. Just like the Siemens Hurricane Range Hood that came to the Pacific Internet Appliances Channel, this Siemens LC58FK951W range hood is designed in a European style. Equipped with five breakthrough technologies, including BLDC DC brushless frequency conversion motor, hurricane speed suction, 3D frequency conversion self-cleaning, Ling Guang intelligent control and deep seamless smoke chamber, let Xiaobian will once again enter the Siemens kitchen electricity plant, experience various National standard test.

It can display perfectly in all weathers, and the free slide control system can achieve accurate positioning.
Air volume test
When consumers buy a range hood, they will observe a major performance indicator, which is the amount of exhaust. Exhaust volume refers to the amount of exhaust air per unit time when the hood reaches the highest position, which is the suction size we often say. At present, according to GB/T17713-2011 national standards, the air volume value needs to be ≥10m3/min. In general, the greater the amount of air flow, the faster and cleaner the fumes in the kitchen are, ie, as large a range of hoods as possible.
We came to the Siemens kitchen and electricity plant to test the air volume test device of the range hood. The measurement principle is to obstruct the principle of object flow measurement. Using a standard long-path low-speed nozzle as an obstruction, the air flow through the nozzle is measured by measuring the static pressure difference across the standard nozzle.
After this air flow test device, it was found that this Siemens LC58FK951W range hood using BLDC DC brushless frequency conversion motor, can provide users with a constant large suction 18.1m3/min, while the open hurricane speed suction mode can swiftly rise to 20.27m3 /min, is very suitable for Chinese families stir fry habits.

Grease separation test
For relative air volume tests, the grease separation test is unfamiliar to the average consumer. In fact, the degree of grease separation directly affects the key indicators of the degree of soot accumulation inside the machine. When cooking, fumes will not only escape to the outside with the flue, but more oil will be hidden inside the machine and finally be put into the oil box. The degree of separation of oil and fat is an important indicator of the ability to separate grease inside the machine. The higher the degree of separation of oils and fats, the better the effect of the oil filter on the hood and the less fumes discharged into the atmosphere, the more favorable to the environment.
To test grease separation, we will simulate the environment of the kitchen, consisting of the main tank, drip system, temperature control system, independent filter and auxiliary fan. By separating the water droplets into the oil, smoke is formed to test the oil separation effect of the hood.
At present, the national standard GB/T17713-2001 of the range hood has a degree of separation of not less than 80%. From the test results, the Siemens LC58FK951W range hood has a grease separation degree of 95.6% which is much higher than the national standard. It indicates that the higher the degree of separation of oils, the better the effect of the oil filter on the hood, and the less fumes discharged into the atmosphere, the more favorable to the environment.
Odor reduction test
After a series of complicated changes in cooking oil and food in the kitchen under high temperature conditions, a large number of thermal oxidation decomposition products are generated, some of which are emitted into the air in the form of smoke to form kitchen fumes. In fact, the composition of oil smoke is complex: there are a total of more than 220 kinds of aldehydes, ketones, fatty acids, alcohols, aromatic lipid compounds, lipids, lactones, and heterocyclic compounds, most of which are poisonous. Therefore, when purchasing a range hood, in addition to paying attention to the size of the suction, the degree of odor reduction is also an extremely important reference indicator.
When the maximum odor concentration is released in the laboratory under the specified test conditions, the maximum odor concentration value measured during the working range of the range hood within 30 minutes. The bigger the better, it means that the smoke is better. According to the national standard, the normal odor reduction of the range hood is ≥ 90%.
Through the inspection of professional laboratories, it can be seen that the normal odor reduction can reach 99.46%, which is definitely a smoke-absorbing range hood.
Working noise test
Noise testing is a concern for consumers. After all, the size of the kitchen itself is relatively small. If the noise from the hood is too high, cooking in it for a long time is very unfavorable for the health.
The working smoke of the range hood of the national standard GB/T17713-2011 of the range hood can't exceed 73 decibels. This index can be measured by trialing the range hood when purchasing. When the high-quality hood is in operation, the motor runs smoothly and the assembly of the products is tightly stitched, so no large working noise will occur and the entire system will exhibit a smooth operation.
The lowest position is 56 decibels and the maximum is 69.6 decibels
We also conducted tests in professional laboratories to see the noise in its lowest gear and working hours in the maximum gear, which were 56 decibels and 69.6 decibels, respectively.
Digi joint control system test
Siemens home appliances this range hood, in the end how smart it? It is equipped with digi control system, can fully realize the one-on-one linkage control between the stove and the smoke machine: When the stove is ignited, the range hood immediately activates. After the cooker is turned off, the hood automatically shuts off after 3 minutes. Everything is in such a tacit agreement that it will not allow smoke fumes to stay in the air for more than a few moments, and it will not let you use the switch hood when you are busy with other kitchen affairs. It is easy to have a healthy and refreshing kitchen.
Linkage test video
From the video, you can see that when Xiao Bian turns on the gas stove, the hood will be immediately turned on, and no longer need to reach out and touch the hood. When shutting off the heat, in order to ensure that the fumes will be sucked cleanly, it will be automatically delayed after 3 minutes. Its digi control system has once again played a role. Siemens Home Appliances has used the joint control method to make kitchen appliances smarter. It has to be amazed that technological progress is the convenience that you inadvertently bring to life.
