Embodiment 1

[0051] In this embodiment, a washing machine that uses a motor to generate sound can use the motor to play selected songs, so that the washing machine has a music playback function, and then use the motor to generate music during the user's washing process to reduce washing noise and improve the user's washing experience. Use experience. At the same time, the user can use the washing machine to play music, so as to improve the communication and interaction between the washing machine and the user, and increase the user's enjoyment of using the washing machine.

[0052] Such as figure 2 As shown, in this embodiment, the specific working process of the washing machine using the motor to play music is as follows:

[0053] Step 1. Select a song, and the washing machine calls the tone score of the corresponding song;

[0054] Step 2. According to the sequence of the songs, the washing machine sequentially calls the corresponding tone group Xn in the tone music score;

[0055] S...

Embodiment 2

[0068] This embodiment is based on the first embodiment above, and the theme song "Song of Leo" of "Haier Brothers" is taken as an example for illustration. The first score and lyrics of "Leo's Song" are as follows:

[0069] Score:|3 3 3 2 1|1 3 5--

[0070] Lyrics: Thunder will rain Leo...

[0071] In this embodiment, the first tone "3" of "Song of Leo" corresponds to the first tone group X1 in the tone score in the memory of the washing machine, and the tone group X1 includes three numerical information A1, B1 respectively , C1; the described note value A1 is 3, corresponding to the note "3"; the described pitch value B1 is 2, corresponding to the middle tone; the described time value value C1 is 2, corresponding to the pronunciation time being two One-half beat, that is, the duration corresponding to one beat.

[0072] At the same time, the tone group X1 is corresponding to the preset tone group, and the corresponding current frequency pre-stored value is h10. From this...

Embodiment 3

[0075] In this embodiment, a washing machine that uses a motor to generate sound, the washing machine can use the motor to generate sound, so as to generate an alarm sound when the washing machine fails, and generate a prompt sound when the washing machine reaches the washing node, so that the motor can be used as the generating device of the washing machine. Play various notification sounds and alarm sounds of the washing machine.

[0076] Through the above setting, the motor directly emits sound, so that the setting of separate audio output devices such as speakers on the washing machine is canceled, the number of parts of the washing machine is reduced, and the production cost of the washing machine is compressed.

[0077] In this embodiment, when the motor generates sound, the frequency of the current fed into the electromagnetic coil of the stator is in the first frequency range H1; the first frequency range H1 is the frequency range of the motor. When the electric curren...

Abstract

The invention relates to a method and washing machine for producing sounds by utilizing a motor in the field of washing machines. The motor is connected with a power supply of the washing machine through a frequency converter so that current with different frequencies can be input to the motor and then the motor can produce sounds with corresponding tones. Through controlling input current of the motor, the aim of playing corresponding music, alarm sounds and prompt sounds by the washing machine can be realized through adjusting the sounds produced by the motor. Meanwhile, the washing machine is simple in structure, concise in method, remarkable in effect and suitable for popularization and application.

Description

technical field [0001] The present invention relates to the field of washing equipment, in particular to a washing machine that uses a motor to generate sound, in particular to a washing machine that uses a washing motor to play music; and also relates to a method for using a motor to generate sound of a corresponding tone. Background technique [0002] Currently, for washing machines with music playing function, an independent audio player is generally installed on the washing machine, so that the washing machine can realize the function of playing songs, so as to reduce the disturbance of noise to the user during the washing process. [0003] For example, the Chinese patent with application number CN201120515618.3 provides a singing washing machine, which is composed of a washing machine main body, a music player and a sound system. Next to the control buttons, the music player has touch buttons and a memory card inside. Through the above arrangement, the combination of t...
