AI Technical Summary

Technical Problem

During operation, existing dryers have difficulty effectively eliminating low- and mid-frequency noise, especially the noise generated by compressor vibration and wind noise, which is difficult to control through sound insulation and sound absorption methods.

Method used

Active noise cancellation technology is used to collect noise through a noise-canceling microphone and use a noise-canceling speaker to emit an opposite sound to suppress the noise. The noise-canceling microphone, a first noise-canceling speaker, and a second noise-canceling speaker are mounted on a noise-canceling component bracket and fixed at different positions on the dryer to cover the main noise source.

Benefits of technology

It effectively reduces low-to-medium frequency noise during dryer operation, improving the user experience.

[0018] The present application will be further described below with reference to the accompanying drawings.

[0019] The clothes dryer with the active noise reduction function comprises a base 1, a front support assembly 2, a noise reduction assembly 3, a rear plate assembly 4, a drum assembly 5, a right side plate 6, a left side plate 7 and an upper cover plate 8. The front support assembly 2 is mounted on the front part of the base 1, and the lower part of the rear plate assembly 4 is connected to the rear part of the base 1. The drum assembly 5 is mounted between the rear plate assembly 4 and the front support assembly 2. The compressor 1-1 and the motor 1-2 are mounted on the base 1 and below the drum assembly 5. The left side plate 7 is mounted on the left side of the base 1 and together with the rear plate assembly 4, and the right side plate 6 is mounted on the right side of the base 1 and together with the rear plate assembly 4. The upper cover plate 8 is mounted above the drum assembly 5 and together with the rear plate assembly 4.

[0020] The lower left side, the lower right side and the upper part of the drum assembly 5 are respectively provided with the noise reduction assembly 3. The noise reduction assembly 3 on the lower left side is fixed to the inner side of the left side plate 7 and mainly suppresses the noise of the drum. The noise reduction assembly 3 on the lower right side is fixed to the inner side of the right side plate 1 and mainly suppresses the noise of the drum and the noise during the operation of the compressor and the motor.
