Embodiment 1

[0103] Such as figure 2 As shown, the dehydration control method of the self-cleaning washing machine in this embodiment:

[0104] (1) Drainage begins, open the drain valve, and enter the next step;

[0105] (2) Detect water level L, judge whether L≤L5, if so, then enter step (6), if not, then enter next step;

[0106] (3) Determine whether L≤L4, L4

[0107] (4) Close the drain valve, control the inner barrel to rotate at a speed of V1=200RPM for 2S, and enter the next step;

[0108] (5) Open the drain valve, control the inner barrel to rotate at a speed of V4=20RPM until L≤L5, and enter the next step;

[0109] (6) Execute the dehydration program until the end of dehydration.

[0110] L5 corresponds to the empty bucket point judged by the water level sensor of the washing machine. If the water level reaches L5, it will immediately enter the dehydration program. When there is a lot of water...

Embodiment 2

[0112] Such as image 3 As shown, the self-cleaning washing machine drainage and dehydration control method in this embodiment:

[0113] (1) Drainage begins, open the drain valve, and enter the next step;

[0114] (2) Detect the water level L, judge whether L≤L5, if so, then enter step (9), if not, then enter the next step;

[0115] (3) judge whether L≤L4, if so, then enter the next step, if not, then enter step (6);

[0116] (4) Close the drain valve, control the inner barrel to rotate at a speed of V1=160RPM for 3S, and enter the next step;

[0117] (5) Open the drain valve, control the inner barrel to rotate at a speed of V4=30RPM until L≤L5, and enter step (9);

[0118] (6) Determine whether L≤L3, if so, enter the next step, if not, drain water until L≤L3, and enter the next step;

[0119] (7) Determine whether it is dehydration after washing, if so, close the drain valve, control the inner barrel to rotate at a speed of V2=100RPM for 4S, and enter the next step, if no...

Embodiment 3

[0123] Such as Figure 4 As shown, the self-cleaning washing machine drainage and dehydration control method in this embodiment:

[0124] (1) Drainage begins, open the drain valve, and enter the next step;

[0125] (2) Detect water level L, judge whether L≤L5, if so, then enter step (11), if not, then enter next step;

[0126] (3) judge whether L≤L4, if so, then enter the next step, if not, then enter step (6);

[0127] (4) Close the drain valve, control the inner bucket to rotate for 2S at the speed V1=150RPM, and enter the next step;

[0128] (5) Open the drain valve, control the inner bucket to rotate with the rotating speed V4=20RPM, until L≤L5, enter step (11);

[0129] (6) judge whether L≤L3, if so, then enter the next step, if not, then enter step (9);

[0130] (7) Determine whether it is dehydration after washing, if so, close the drain valve, control the inner barrel to rotate at a speed of V2=80RPM for 5 seconds, and enter the next step, if not, close the drain v...

Abstract

The invention discloses a water drainage and dehydration control method of a self-cleaning washing machine. Cleaning particles moving along water flow to clean the outer wall of an inner tub and the inner wall of an outer tub are arranged in the space between the inner tub and the outer tub of the washing machine, a water drainage instruction is received to turn on a water drainage valve; the water level is judged; the amount of the cleaning particles per unit volume of the water in the space is judged; the rotating speed of the inner tub is controlled to adjust the friction and collision frequency between the cleaning particles and the inner and outer tubs. The water drainage and dehydration process of the washing machine is divided into at least two control stages according to the water level, different inner tub rotation modes are set for each stage, and the rotation speed of the inner tub is higher at the stage of lower water level. At a control stage, an inner tub rotation control method comprises the steps of turning off the water drainage valve, controlling the inner tub to set rotation speed, turning on the water drainage valve after rotation for set time, controlling the inner tub to rotate at the other set rotation speed, judging the water level, and executing a next control stage when the water level corresponding to the next stage is met. The control method is simple, dirt on the walls of the tubs of the washing machine can be completely removed, a washing environment is kept clean, secondary pollution is completely eradicated, and clothes cleaning rate is improved.
