Although I always feel that there is no need to buy home appliances that are too expensive, there is an indisputable fact that some ordinary home appliances can only be discovered by truly experiencing them after buying them home.
For example, the "4 types of home appliances" below. If you choose a low-end model or a normal model, will most likely be dissuaded from "noise" .
1. wall breaker
There are too many people who thought that changing the soy milk machine to a "wall breaker" can "show off", but after real use, you will find that the wall breaker is very "unfriendly" during operation. This useless experience is not a functional defect, but a problem from "noise".
The wall breakers on the market have many types and numbers, and the prices are also uneven. From a few hundred yuan to thousands of yuan, the wall-breaking machine market that is mixed with fish and dragons must pay attention to the parameter "noise value". Many wall breakers that cost hundreds of yuan can even reach eighty or ninety-ninety degrees.
and high-end wall breakers, noise value can even be controlled below 60 decibels .
In fact, the noise value is low and the design requirements for the wall breaker are very high. To reduce the noise while maintaining a certain speed, various components need to be connected, such as the design of the internal structure and the design of the external sound insulation cover, etc.
So this also reminds us that you must not be cheap when choosing a wall breaker. To be honest, as a veteran food lover, the noise of the wall breaker with a soundproof cover that you bought a few years ago can still soar to 70 decibels, and it is now idle. I advise everyone that if you buy a wall breaker, you can ignore other parameters, but the "noise value" must not be ignored !
Put a comparison picture of the noise scene to intuitively experience it:
If the noise of the wall breaker is controlled at 70 decibels, it is barely acceptable. If it exceeds 70 decibels, don’t invest it. After all, noise will not only affect your own mood of cooking, but also affect the harmony of your neighbors.
2. Range hood
Many people may not know that the noise value of range hood has national standards. According to national regulations, the noise of the range hood shall not exceed 65 decibels-68 decibels. Looking at the range hoods on the market today, the noise value of most ordinary range hoods is around 65 decibels (models or miscellaneous hoods within 1,000 yuan).
and 65 decibels of noise actually have a relatively large interference to the ears , so it will naturally bring bad experience to people who cook.
It is recommended that when purchasing a range hood, it is best to consider models with noise values of about 50 decibels. For example, the range hoods of mainstream brands such as the boss and can basically be controlled below 60 decibels for any hood that costs more than 2,000 yuan.
For example, the boss CXW-260-28D3S and Fangtai CXW-358-EMC5A are priced around 2,500 yuan, and the noise value is lower than 55 decibels. Especially the boss, the noise value is even as low as 50 decibels. A hood like is a relatively cost-effective model, and of course it is also the most worth investing in (by the way, there is no need to buy a hood too good, two or three thousand yuan is enough).
3. Washing machine
The market price of washing machines is getting lower and lower, and even the price of washing and drying machine has dropped to 2,000 yuan. However, in terms of purchasing, I still recommend that you not choose ones that are too cheap. After all, "you get what you pay for" and the difference in price is actually the difference in materials, structure, motors, etc. . These differences are often reflected in washing efficiency, damage rate and noise.
Whether it is drum washing machine , washing and drying machine or pulsator washing machine , many people will consider elements such as "capacity, energy efficiency level, function, brand", but they often ignore the parameter "noise value".
In fact, low-end washing machines do a poor job of noise control. Take an early drum washing machine in my home as an example. The washing noise is more than 60 dB, and the dehydration noise is even more than 78 dB .To be honest, every time I wash my clothes, I feel upset by the noise. This experience is very uncomfortable. Of course, this is also the main reason why I replaced it in the end.
By the way: Many washing machines do not indicate their noise value. At this time, you need to ask the merchants about . It is not misleading, but a lesson!
4. Refrigerator
Will your refrigerator make a "buzzing" sound after using it for a long time? When many people only care about capacity, energy efficiency level, door opening method and fresh-cold technology, they do not know that "noise" can also demonstrate the quality of the refrigerator (the design, structure and so on of fan/ compressor and internal components will affect the noise value).
Refrigerators that can truly achieve "low-noise operation" must be high-end refrigerators with relatively high prices. In contrast, most of the refrigerators with noise exceeding 40 decibels are entry-level models that are less than 2,000 yuan. Although the noise of refrigerators is the smallest among all home appliances, you will find that the noise emitted by low-end refrigerators will also affect the happiness of home life.
Therefore, it is recommended that when purchasing refrigerators, try to choose models with noise control within 40dB. For example, Haier BCD-521WGHSSEDSD large-capacity double-door refrigerator , which is priced at less than 3,000 yuan, and uses variable frequency centrifugal fans and variable frequency compressors, which can maintain low noise operation of 38dB noise.
