Nowadays, urban people have a lot of work pressure. If they want to get more spare time, they must rely on various machines to do housework after returning home. The washing machine is a home appliance that can hardly be found. In the previous issue, our PConline home appliance evaluation room also conducted a pro-test on the dehydration of the washing machine, and analyzed the dehydration effect.
First of all, I would like to thank the netizens for their reading and have had a heated discussion. Some discussions are also very interesting, and many people are doubtful and curious about the dehydration effect. One of the netizens mentioned: "I don't explain what the different files have. According to the article, it is directly on the highest level." It sounds quite reasonable. It is just the dehydration efficiency. Why not use the most high-end? What?
Dialectical with test data
In fact, it is not necessary to consider the noise and power consumption between the gears of different speeds. According to common sense, the lower the speed, the lower the noise and power consumption, and vice versa. However, it is useless to say that, we still come to the actual measurement and record the data, using objective facts to dialect the problem.
The test object is still this small hair quilt, which is completely wet before each position test. Then we use a drum washing machine of a certain brand, which has 400, 600, 800, 1000, 1200, 1400 six-speed dehydration speed. We also unified the dehydration time to 10 minutes/time and measured an ambient noise of 44.4 dB.
At a speed of 400, the lowest noise was recorded at 48.5 dB, the highest noise was 56.7 dB, the noise difference was 8.2 dB, and the power consumption was 0.01 kWh.
At a speed of 600, the lowest noise was recorded at 48.6 dB, the highest noise was 56.8 dB, the noise difference was 8.2 dB, and the power consumption was 0.01 kWh.
At a speed of 800, the lowest noise was recorded at 49.0 dB, the highest noise was 57.3 dB, the noise difference was 8.3 dB, and the power consumption was 0.01 kWh.
At a speed of 1000, the lowest noise was recorded at 48.8 dB, the highest noise was 58.2 dB, the noise difference was 9.4 dB, and the power consumption was 0.01 kWh.
At a speed of 1200, the lowest noise was recorded at 49.4 dB, the highest noise was 58.8 dB, the noise difference was 9.4 dB, and the power consumption was 0.01 kWh.
At a speed of 1400, the lowest noise was recorded at 49.5 dB, the highest noise was 62.7 dB, the noise difference was 13.2 dB, and the power consumption was 0.02 kWh.
The digital gap is small and the actual impact is large.
| Decibel level | |
| 0-20 decibels | Very quiet, almost imperceptible |
| 20-40 decibels | Quiet, like a whisper |
| 40-60 decibels | General, ordinary indoor conversation |
| 60-70 decibels | Noisy, detrimental nerve |
| 70-90 decibels | Very noisy, nerve cells are damaged |
| 90-100 decibels | Increased noise, hearing loss |
| 100-120 decibels | Unbearable, stay for a minute and be temporarily swearing |
| 120 decibels or more | Extremely paralyzed or full |
| 300 decibels or more | Unrepairable deafness for a person of 20km |
After reading the data, it is also consistent with the direction of the guess before the test. The lower the speed of dehydration, the lower the noise and power consumption. The noise difference also increases with the higher the speed, but the change in power consumption is not as large as the noise change, and it can be seen that noise is one of the main considerations.
At night, it is recommended to use the dehydration gear of 400-600 rpm. The user who is on the balcony or bathroom actually feels quite quiet. For daily use, the 800-1200 rpm dehydration gear can satisfy most people. Demand, only need to be properly selected according to the actual environmental noise; and the highest dewatering position is often suitable for some cases that are more eager to dry, or the position of the washing machine itself is designed to effectively suppress noise.
in conclusion
It can be concluded that the higher the dehydration effect is the most obvious, but the cost is that the higher the power consumption, the greater the noise. Therefore, there is no choice to say that the most upscale is the worry-free choice. Before using the dehydration program, it is necessary to consider the environment and purpose. Only the best choice, there is no best choice.
