Problems solved by technology

[0002] The current washing machine, especially the drum washing machine, runs at a high speed when the drum washing machine is dehydrating, and the water on the clothes is thrown out through the action of centrifugal force, but it will generate a lot of airflow noise. , form an eccentric load, and generate vibration and noise when the inner drum rotates at a high speed, which often leads to emotional dissatisfaction among customers who buy washing machines, and also makes some drum washing machines less competitive in the market

Embodiment 1

[0013] Embodiment 1: The method for sound insulation and noise reduction of a washing machine in this embodiment, puts the sound insulation coating 20 into a spray gun, and sprays directly on the outer surface 11 and inner surface 12 of the outer cylinder 10 of the washing machine, and the spraying thickness is 0.5 mm. When the drum washing machine is performing high-speed dehydration, the sound insulation coating 20 has fine particles with sound insulation effect, which can reduce the sound wave energy transmitted by the outer cylinder of the washing machine, thereby achieving the effect of sound insulation and noise reduction. Test a LG Prime Refresh WD-T12345D type drum washing machine, and conduct a comparative test with and without using the sound insulation and noise reduction method of the present invention. When the noise is 0.5 to 1 decibel, it has achieved the effect of sound insulation and noise reduction.

Embodiment 2

[0014] Embodiment 2: The sound insulation and noise reduction method of the washing machine in this embodiment, put the sound insulation coating 20 into the spray gun, and directly spray the outer surface 11 and the inner surface 12 of the outer cylinder 10 of the washing machine, and the spraying thickness is 2mm. When the drum washing machine is performing high-speed dehydration, the sound insulation coating 20 has fine particles with sound insulation effect, which can reduce the sound wave energy transmitted by the outer cylinder of the washing machine, thereby achieving the effect of sound insulation and noise reduction. Test a LG Prime Refresh WD-T12345D model drum washing machine, and conduct a comparative test with and without adopting the sound insulation and noise reduction method of the present invention. When the noise is 0.5 to 2 decibels, it achieves the effect of sound insulation and noise reduction.

Embodiment 3

[0015] Embodiment 3: The sound insulation and noise reduction method of the washing machine in this embodiment, the sound insulation coating 20 is put into the spray gun, and the outer surface 11 and the inner surface 12 of the outer cylinder 10 of the washing machine are directly sprayed, and the spraying thickness is 3mm. When the drum washing machine is performing high-speed dehydration, the sound insulation coating 20 has fine particles with sound insulation effect, which can reduce the sound wave energy transmitted by the outer cylinder of the washing machine, thereby achieving the effect of sound insulation and noise reduction. Test a LG Prime Refresh WD-T12345D model drum washing machine, and conduct a comparative test with and without adopting the sound insulation and noise reduction method of the present invention. When the noise is 1.5 to 3 decibels, it has achieved the effect of sound insulation and noise reduction.

Abstract

The invention discloses a sound isolation and noise reduction method for a washing machine. According to the method, a sound isolation coating is coated on the surface of an outer barrel of the washing machine, micro particles having a sound isolation effect are uniformly distributed in the sound isolation coating, and transmitting sound wave energy is reduced, so that the effect of sound isolation and noise reduction is achieved.

Description

technical field [0001] The invention relates to a sound insulation and noise reduction method, in particular to a sound insulation and noise reduction method for a washing machine. Background technique [0002] The current washing machine, especially the drum washing machine, runs at a high speed when the drum washing machine is dehydrating, and the water on the clothes is thrown out through the action of centrifugal force, but it will generate a lot of airflow noise. , Forming an eccentric load, vibration and noise are generated when the inner drum rotates at a high speed, which leads to emotional dissatisfaction among customers who buy washing machines, and also makes some drum washing machines less competitive in the market. [0003] Therefore, a new technical solution is needed to solve the above problems. Contents of the invention [0004] In view of the problems and deficiencies in the above-mentioned prior art, the object of the present invention is to provide a me...
