In the dead of night, you're expecting to fall asleep, only to be awakened by the screeching noise of a balcony dryer. In your panic, You Wonder: What's wrong with the dryer? Don't panic, this article will give you an in-depth analysis of the causes of noise and share practical noise reduction methods to help you find a quiet night.

1、Mechanical vibration

(1) analysis of the causes

Dryer drum motor driven by high-speed rotation, if installed when the drum tilt, even the naked eye is difficult to detect the small angle, will lead to serious imbalance of the drum. In addition, support roller bearing wear loose for a long time, also can cause violent vibration, produce low“Dongdong” sound, let a person upset.

(2) practical solutions

①. Precise leveling

Calibrate the dryer with a professional level and place it on the top and side to observe the bubble position. If the bubble deviates from the center, indicating that the machine is not horizontal, need to adjust the height of the four mats, so that the bubble return to ensure that the machine stable. Adjustment can be made with the help of wrenches and other small tools to fine-tune the mat.

②. Bearing maintenance

Regularly check the bearing wear, loose or abnormal response to timely replacement. When replacing the original quality reliable accessories or well-known brands compatible accessories, install new bearings to ensure that in place, and apply the right amount of grease to reduce friction and wear, prolong service life.

2、Aerodynamics

(1) analysis of the causes

When the air flowed in the narrow and tortuous air duct, it would produce complex turbulence and vortex due to obstruction, causing sharp whistling and roaring, it's like there's a storm raging inside the machine.

(2) practical solutions

①. Optimize air ducts

Check whether the air duct is blocked or deformed. If there are dust, hair and other foreign bodies, clean them with a professional vacuum cleaner or a slender brush. The deformed or damaged air ducts should be replaced in time, and the products with the same specifications as the original air ducts should be selected for replacement, make sure the air flow is unimpeded.

②. Install mufflers

Multi-layer composite structure muffler is installed in the air duct to absorb, reflect and attenuate noise by acoustic principle. Install according to the instructions, to ensure that the installation is firm, correct position, and according to the dryer model and noise characteristics to choose the right muffler.

3、Collision of articles

(1) analysis of the causes

In the dryer drum, the clothes roll and collide with each other at high speed. If a garment has hard buttons, zippers, or several pieces of clothing tangled together, there will be a clashing sound, as if there were a fierce battle inside the roller.

(2) practical solutions

①. Separate drying

Before drying clothes, the clothes with buttons, zippers and other clothing separate, easy to wrap clothing such as sheets, quilts, etc. first shake out and then put into the dryer, reduce clothing collision and winding, reduce noise.

②. Use an anti-winding ball

Put several anti-entanglement balls in the dryer. They roll between clothes, increasing friction and preventing entanglement. They also cushion collisions and reduce noise. Anti-winding balls can be purchased at home supply stores or online.

4、Sound insulation of the whole machine

(1) analysis of the causes

Even with these measures, there may still be noise leakage from the inside of the machine, this is because the dryer shell sound insulation effect is limited, can not completely block the spread of noise.

(2) practical solutions

①. Add soundproofing cotton

The inner side of the outer shell of the dryer is pasted with a sound insulation cotton with high density and good sound absorption effect, which can effectively absorb the internal noise of the machine. Paste to ensure that the firm, to avoid gaps.

②. Use of noise enclosures

If conditions permit, can be customized for the dryer noise enclosure, with sound-absorbing effect of the foam board or sound insulation felt production. Production to set aside the necessary vents to ensure that the dryer heat normal, all-round reduction of noise transmission.

5、Installation and use

(1) analysis of the causes

The details of installation and use are crucial to noise reduction. If the dryer is not installed smoothly and the height of the four floor mats is not the same, additional vibration and noise will be generated during operation. If the filter and condenser are not cleaned regularly, dust, hair and other debris will block the operation of the machine, generate additional noise.

(2) practical solutions

①. Professional installation

The best installation of dryers please professional operation, they are experienced, professional tools to ensure that the installation of a smooth and firm. Installation should be carried out in strict accordance with the requirements of the manual to ensure that each link in line with standards.

②. Clean up regularly

Develop a regular cleaning dryer habits, at least once a week to clean the filter, remove dust, hair and other debris; once a month to clean the condenser, can be washed with professional cleaners or water. Clean up to pay attention to power-off operation to ensure safety.

Conclusion

By thoroughly analyzing the causes of dryer noise and sharing practical noise reduction methods, I believe you have a clear understanding of the solution to the problem of dryer noise. As long as from the mechanical vibration, aerodynamics, goods collision, sound insulation and installation and use of the machine, according to the method of operation, can effectively reduce noise, say goodbye to the“Noise Nightmare”. Let us use the power of science and technology, to embrace the quiet and comfortable home life, enjoy a good night.
