/ Asahi/Guangzhou, February 15, 2022 -- As the saying goes, the year is not over until the Lantern Festival. In ancient times, Lantern Festival was no less lively than New Year's Eve, but nowadays, apart from a round family dinner, there seems to be no more sense of ceremony. To this end, they will surely seize the opportunity to show off their talents and draw a perfect end to the Spring Festival holiday. The only worry about this dinner, however, was the room full of fireworks and annoying rumbling noises. A new generation of kitchen efficiency and silence artifact, A.O. Smith's new "Ching" range hood, breaks the awkwardness. After several tests, this range hood can keep the family meal away from the lampblack and noise, thus stepping into a new realm of "very quiet, very clean" kitchen.
As we all know, noise, as a "chronic disease" in the range hood industry, is also the most criticized pain point by users. Based on general knowledge, if the low speed noise is understandable, then the high suction must bring more noise. But as the Ching hood advertises - even the maximum gear noise can have a "mute" effect.
Top side double suction eliminates oil smoke unassailable
The new generation of "Ching" lampblack machine retains the top-side double-suction design, so the effect should also be impeccable. The only unique feature is the distributed installation, with the fan separated from the main body and hidden in the ceiling. The overall effect after installation is very beautiful.
First test with smoke cake, open the range hood, overflowing smoke is immediately sucked away, good suction, and small noise.
The silent experience feels like magic
While in the kitchen you previously needed to turn off the range hood to listen to others clearly, changing the "Ching" hood makes it possible to have a clear conversation without turning it off. Suction completely not to the previous generation of top side double range hood.
Real evaluation excellence is evident
A.O. Smith's new "Ching" range hood does sound quiet, but is the "quiet" advantage over a traditional range hood significant enough? See the real chapter of the experiment, to witness the effect of real evaluation in the home environment.
In order to compare, we tested the previous generation of top side dual range hoods in the same environment in advance. First, verify the air volume of the two range hoods. In household environment, the wind speed at the inlet of the two products was tested respectively.
Note: The air volume of the top side double range hood of the previous generation is calculated by measuring the average wind speed at 5 points in the air outlet pipe
The maximum wind speed of the "Ching" range hood is about 2.82m/s, and the working air volume in the test is 840m? / h (14.0 m? /min).
Under the premise of similar air volume, let's look at the performance of working noise.
In a household kitchen environment with ambient noise of about 35.0 decibels, the noise value of the highest gear of the two lampblack machines at the position used by the simulated cook (height 1.5m, 0.7m away from the wall where the lampblack machine is located) was tested respectively.
Noise not only makes people upset, in a noisy environment for a long time, it will also have a certain adverse effect on people's eardrums. To get a more intuitive sense of the mute effect of the "Ching" hood, we did a small experiment to make the noise visible. The difference in noise intensity is clearly shown by the difference in the amplitude of the ball.
Test data are shown in the following table:
It can be seen that the air volume of A.O. Smith's new-generation "Ching" hood is similar to that of the previous generation's top-side dual hood, but the noise is greatly reduced, which is consistent with the initial subjective feeling.

The authoritative certification is well deserved
Through the above comparative tests,A.O. Smith "Ching" lampblack really does deserve its name, proving that the pursuit of big suction is not incompatible with silence.
At present, this new product has passed the "Jiadian" evaluation of the design research and evaluation center of China Household Electrical Appliances Research Institute, and also obtained the Beijing Light Link certification Center Level 1 mute certification.
Level 1 Silence certification refers to the product certification according to the following range hood silence performance classification index,A.O. All the test results of Smith's "Ching" range hood meet the requirements of level 1 silence.
A.O. Smith "Ching" range hood is very quiet and clean. It not only creates a quiet and clean kitchen environment, but also focuses on creating high-quality and comfortable home life. The kitchen is no longer a personal battlefield. The open kitchen door makes communication easier. Here, couples prepare a dinner together, allowing both parties to enjoy the most relaxed state, natural chat, hear each other's heart.
The most important thing for a happy family is to have a quiet kitchen. Never lower the requirements of life, you deserve a happy future.
