Washing machine capable of improving noise impression and control method

Abstract

The invention belongs to the field of washing machines, and particularly relates to a washing machine capable of improving noise impression and a control method. The washing machine comprises a storage module for storing different types of sound signals, an audio playing module, a driving module and a control module, wherein the audio playing module is used for playing the sound signals; the driving module is used for acquiring first state information of the washing machine before a washing barrel rotates formally, acquiring second state information of the washing machine after the washing barrel rotates formally, and feeding back the first state information and the second state information respectively; the control module is used for calling a sound signal type conforming to the current state information from the storage module according to the first state information fed back by the driving module before the washing barrel rotates officially; and after the washing barrel rotates formally, the audio playing module is controlled to play a sound signal corresponding to the first state information, and the intensity of the sound signal is adjusted according to second state information fed back by the driving module. According to the washing machine and the control method provided by the embodiment of the invention, the timbre and the volume intensity of the washing machine can be intelligently adjusted, the noise impression is improved, and the hearing comfort of a user is improved.

Description

technical field [0001] The invention belongs to the field of washing machines, in particular to a washing machine and a control method for improving noise impression. Background technique [0002] During the dehydration process of the washing machine, the high-speed rotation of the motor will generate relatively large electromagnetic noise, and the high-speed rotation of the drum will generate relatively large wind and mechanical noise, which will bring certain troubles to home life. At present, the methods for dealing with the noise of washing machines mainly adopt passive noise reduction methods, such as structural optimization, sound insulation, sound-absorbing materials, vibration-absorbing materials, etc., but these methods are not very effective in improving the sound quality of washing machines. In the related art, the method of adding additional sound to improve the noise of the washing machine has appeared, but this improvement measure is either to add additional no...

Problems solved by technology

[0002] During the dehydration process of the washing machine, the high-speed rotation of the motor will generate a large electromagnetic sound, and the high-speed rotation of the drum will generate large wind noise and mechanical noise, which will bring certain troubles to home life.

At present, the methods for dealing with the noise of washing machines mainly adopt passive noise reduction methods, such as structural optimization, sound insulation, sound-absorbing materials, vibration-absorbing materials, etc., but these methods are not very effective in improving the sound quality of washing machines.

In the related art, the method of adding additional sound to improve the noise of the washing machine has appeared, but this improvement measure is either to add additional noise detection equipment, or to manually adjust the volume, which cannot be intelligently adjusted according to the noise situation.
