Description

TECHNICAL FIELD

[0001] The present application relates to a washing machine with active noise reduction function, and belongs to the technical field of household appliances. BACKGROUND

[0002] During the operation of the washing machine, large noise is generated due to the vibration of the motor and the whole machine. These noises include the noise generated during the operation of the washing machine and the noise generated during dehydration. Among them, the high-frequency noise can be effectively controlled by sound insulation and sound absorption, but the medium and low-frequency noise is difficult to eliminate fundamentally.

[0003] Therefore, it is necessary to improve the prior art to solve the problems of the prior art. SUMMARY

[0004] The present application is to solve the problems existing in the prior art, and provides a washing machine with active noise reduction function, which can improve the noise during the operation and dehydration of the washing machine.

[0005] The technical scheme adopted by the present application is: a washing machine with active noise reduction function, characterized in that: comprising a box assembly, an upper cover plate assembly installed with the box assembly, and a drum assembly and a noise reduction assembly installed in the box assembly, the noise reduction assembly is arranged around the drum assembly, the noise reduction assembly comprises a noise reduction microphone, a first noise reduction loudspeaker and a second noise reduction loudspeaker, and the noise reduction microphone is located between the first noise reduction loudspeaker and the second noise reduction loudspeaker.

[0006] Further, the noise reduction assembly comprises three groups, which are arranged below the left side, below the right side and above the drum assembly.

[0007] Further, the noise reduction assembly arranged below the left side of the drum assembly is fixed in the left side of the box assembly.

[0008] Further, the noise reduction assembly arranged below the right side of the drum assembly is fixed in the right side of the box assembly.

[0009] Further, the noise reduction assembly arranged above the drum assembly is fixed to the lower side of the upper cover plate assembly.

[0010] Further, the box assembly comprises a box upper support plate and a box lower support plate, and a hanging spring connecting the upper part of the drum assembly and the box upper support plate is arranged between them.

[0011] Further, a shock absorber connecting the lower part of the drum assembly and the box lower support plate is arranged between them.

[0012] The washing machine with active noise reduction function of the present application can effectively reduce the noise during the operation and dehydration of the washing machine. BRIEF DESCRIPTION OF DRAWINGS

[0016] The application will be further described below with reference to the accompanying drawings.

[0017] The washing machine with active noise reduction function comprises a box assembly 1, an upper cover plate assembly 4 installed with the box assembly 1, a drum assembly 2 and a noise reduction assembly 3 installed in the box assembly 1, wherein the box assembly 1 comprises a box upper support plate 1-1 and a box lower support plate 1-2, the upper part of the drum assembly 2 is hung on the box upper support plate 1-1 through a hanging spring 2-1, and the lower part of the drum assembly 2 is fixed on the box lower support plate 1-2 through a shock absorber 2-2.

[0018] The noise reduction assembly 3 comprises a noise reduction microphone 3-1, a first noise reduction loudspeaker 3-2 and a second noise reduction loudspeaker 3-3, and the noise reduction assembly 3 comprises three groups, which are arranged below the left side, below the right side and above the drum assembly 2 respectively. The noise reduction assembly 3 arranged below the left side of the drum assembly 2 is fixed in the left side of the box assembly 1, the noise reduction assembly 3 arranged below the right side of the drum assembly 2 is fixed in the right side of the box assembly 1, and the noise reduction assembly 3 arranged above the drum assembly 2 is fixed below the upper cover plate assembly 4.

[0019] The working principle of the washing machine with active noise reduction function is as follows: the washing machine will emit noise when working, which is mainly suppressed through active noise reduction technology. The noise around the noise reduction assembly 3 is collected through the noise reduction microphone 3-1, and then the sound with opposite frequency spectrum is emitted through the first noise reduction loudspeaker 3-2 and the second noise reduction loudspeaker 3-3 to counter and suppress the noise through the processing of the noise reduction computer board, so as to achieve the purpose of reducing the surrounding noise.

[0020] The above only describes the preferred embodiments of the application, and it should be noted that those skilled in the art can make some improvements without departing from the principles of the application, and these improvements should also be considered as the protection scope of the application.
