Square Semi-automatic Washing Machine Noise Level Analysis

1. Noise Source Analysis
As a semi-automatic washing machine, the noise of Square Semi-automatic Washing Machine mainly comes from the following aspects:

Motor operation noise: The washing machine motor will generate certain vibration and noise during operation. The type, quality and manufacturing process of the motor will directly affect the size of the noise.
Water flow noise: During the washing process, the water will generate noise when passing through the pipe and the washing tub. The water flow speed, pipe design and material of the washing tub will affect the size of the water flow noise.
Pulsator or agitator noise: The impeller or agitator inside the washing tub will rub against the clothes and water during rotation, thereby generating noise. The design, material and manufacturing process of the impeller or agitator will affect the size of this part of the noise.
Dehydration barrel noise: During the dehydration process, the high-speed rotation of the dehydration barrel will generate a lot of noise. The balance of the dehydration barrel, the quality of the bearings and the manufacturing process will affect the size of the dehydration noise.
2. Noise Control Measures
Square Semi-automatic Washing Machine has taken a number of measures in noise control to reduce noise levels and improve user experience.

Select high-quality motors: Use high-efficiency, low-noise motors to reduce vibration and noise during motor operation.

Optimize water flow design: Reduce water flow noise by optimizing pipeline design and washing tub material. At the same time, reasonably control water flow speed to reduce noise caused by water flow impact.
Improve impeller or agitator design: Use a more reasonable impeller or agitator design to reduce friction with clothes and water, thereby reducing noise.
Strengthen the balance of the dehydration barrel: By accurately calculating the weight distribution of the dehydration barrel, ensure that the dehydration barrel remains balanced when rotating at high speed, reduce vibration and noise.
Use shock-absorbing materials: Use shock-absorbing materials such as rubber pads inside and at the bottom of the washing machine to reduce vibration and noise during the operation of the washing machine.
3. Actual noise performance
According to the national standard GB19606 "Noise Limits for Household and Similar Electrical Appliances", the washing noise limit for household or similar electric washing machines is 62dB(A), and the dehydration noise should be controlled within 72dB(A). In actual use, the noise level of Square Semi-automatic Washing Machine can usually meet or exceed this standard.

Washing noise: During the washing process, the noise level of Square Semi-automatic Washing Machine can usually be kept at a low level, about 50-60dB(A). This noise level is acceptable to most users and will not affect their daily life and rest.
Dehydration noise: During the dehydration process, the noise level will increase due to the high-speed rotation of the dehydration barrel. However, Square Semi-automatic Washing Machine can usually control the dehydration noise below 70dB(A) by optimizing the dehydration barrel design and using shock-absorbing materials, ensuring the comfort of users during use.
4. Impact of noise level on users
Noise level not only affects the user experience, but may also have an impact on the user's physical and mental health. Long-term exposure to high noise environment may lead to hearing loss, increased psychological stress and other problems.
