/ Asahi/Guangzhou, April 20, 2022 -- Home appliance giant A.O. With his remarkable innovation ability, Smith has launched the new "Ching" series range hood, which improves the "working environment" of China's fashionable "cooking wives/husbands" and makes semi-open kitchens possible in more Chinese homes. For the semi-open kitchen, "smoke clean" is the first condition, the most effective way is to increase the suction and exhaust air volume, but the air volume is bound to lead to higher noise, when the noise is unbearable, in order to quiet down the air volume, but can not be all smoke removal, will pollute every corner of the home. Do you want to smoke good effect must endure the noise? Is it really not enough to suck clean and use it quietly? Now there is a solution to this dilemma.
Although the Chinese family is not without "fireworks", but with the modern young people pay more and more attention to the beauty of the living room and the environment, many families of the kitchen also from the narrow "small black room" into an open "big platform". Although the quality of the home has been greatly improved, the problem also arises that Chinese kitchens are not as easy to take care of as those in the West who love cold food. They are always full of "fireworks". In the past, you can also install a strong lampblack machine in the small kitchen, and then noisy again at least can let the "lampblack to no trace", now open, not only will greatly affect the environmental condition of the family, over time also have a "negative effect" on the health of the family.
Overturning the tradition of "quiet" and "clean" integration
A.O. Smith engineers spent more than two years of repeated experiments, inspired in an instant, completely overturning the structure design of the traditional range hood, and successfully creating the "Ching" range hood, which is very quiet and very clean.
The first distributed silent structure, the fan is placed on the top, equipped with a new generation of frequency conversion noise reduction fan, through the streamline air duct for noise segmentation labyrinth, to minimize the spread of noise, noise source away from human ears. At the same time, it continues the patented top side double suction smoke removal system, "challenge" oil smoke "zero escape". Turn on the "Ching" range hood to help quiet the kitchen and allow a happy relationship to grow and flourish.
Can you really be very quiet in a home environment? The China Household Electrical Appliances Research Institute tested A.O. in a real kitchen with ambient noise of about 35 decibels. Two generations of Smith top side dual range hoods were tested.
Test data are shown in Table *2:
Under the premise of the same air volume, the maximum gear noise of the top-side dual range hood of the previous generation is 65.0dB(A), while the "Ching" range hood is only 54.5dB(A), showing a very obvious noise reduction effect. In order to visualize the harmful effects of noise on eardrums, the China Household Electrical Appliances Research Institute has also done an interesting experiment with small balls that make noise visible. The difference in noise intensity is clearly shown by the difference in the amplitude of the balls.
At present,A.O. Smith "Ching" range hood has passed the "Jiadian Evaluation" of the Evaluation center of China Household Electrical Appliances Research Institute. At the same time, according to the "Range Hood Mute Classification Evaluation Code" issued by China Hardware Products Association, it has obtained the Beijing ZhongLight Association Certification Center (CCLC) Level 1 mute *3 certification.
People-oriented intelligence worry-free
A.O. Smith independently researched and developed the "human-centered" fully connected and fully controlled intelligent Internet of things system -- AI-LiNK, enabling the original isolated household appliances to realize interconnection. Once carbon monoxide and methane in the kitchen are detected to exceed the standard, the range hood and gas water heater (equipped with AI-LiNK function) will be automatically turned on to exhaust air, quickly discharging harmful gas outdoors, and intelligent protection of family safety all day long.
The very quiet and clean A.O. Smith "Ching" range hood makes the kitchen no longer a battlefield of one person. Here, couples prepare a dinner together, allowing both parties to return to the most relaxed state, naturally chatting, hearing each other's sincerity, and even having a chance to reconcile the difficult relationship.
A good communication environment allows a good relationship to happen. The most important thing for a happy family is to have a quiet kitchen. Those who never lower their demands on life deserve a happy future.
