Referring to fig. 1 to 4 in combination, according to an embodiment of the present application, a control method of a washing machine includes:

pre-bleaching, main washing and bleaching which are operated in sequence;

the pre-bleaching comprises the steps of spraying the clothes 3 in the washing drum 2 to separate sundries on the clothes 3; and simultaneously, the drainage channel 4 of the washing drum 2 is opened to discharge sewage containing sundries.

This application sets up the prebleaching before main washing and takes off, breaks away from clothing 3 with debris through spraying to in time wash a section of thick bamboo 2 along 4 discharges of drainage channel, be favorable to subsequent main washing to wash cleanly and the rinsing.

An independent pre-bleaching process is additionally arranged before main washing water enters, water is discharged before the main washing water enters, and partial dirt (such as particle dirt) can be discharged out of the washing device in advance to achieve the effect of pre-cleaning; in the pre-rinsing process, the drainage pumps are simultaneously opened in the spraying process, and the dirty mixed water is drained in time, so that on one hand, partial dirty is drained in advance, and the situation that the dirty water is not drained is avoided, the dirty water returns to the clothes 3 along with the increase of the main washing water and the rotation of the barrel, and the dirty water is drained in time, so that the following cleaning and rinsing effects are facilitated; on the other hand, the water is discharged while spraying, so that the phenomenon that the water quantity accumulation cylinder rotates to bring water to cause overlarge vibration or noise is avoided, and the effects of vibration reduction and noise reduction are also achieved.

In some embodiments, the pre-rinsing further comprises controlling the rotation of the washing drum 2 to spray the underwear 3 on the washing drum 2 when the first rotation speed is reached.

In the pre-bleaching and removing process, the inner cylinder rotates at a high speed during spraying, on one hand, the high-speed centrifugal force is large, partial stains on the clothes 3 can be quickly stripped out and thrown to the bottom of the outer cylinder, and the effect of removing stain particles can be achieved; on the other hand, the rotating speed is high, so that water sprayed on the clothes 3 can quickly permeate and emerge from the clothes 3 to bring out dirt, the phenomenon that the eccentricity is too large is avoided, the rotating speed is high, the resonance interval is effectively avoided, and the effect of reducing vibration is achieved; because the inner barrel rotates at a high speed in the pre-bleaching and dehydrating process, the clothes 3 are spread out and attached to the barrel wall, and the spray water directly acts on the clothes 3, so that the effect of quickly wetting the clothes 3 can be achieved.

In some embodiments, pre-bleaching further comprises decreasing the rotation speed of the washing drum 2 to a second rotation speed when the contaminated water is drained.

The pre-bleaching process is followed by the water inflow of the main washing, the rotating speed is reduced after the pre-bleaching sewage is drained, the water inflow of the main washing is facilitated, and the vibration noise caused by large water storage amount of the main washing is avoided.

In some embodiments, the washing machine comprises a shower head, the spraying area of which comprises all the laundry 3 in the axial direction inside the washing drum 2.

The spray head communicated with the spray pipe 1 is adopted to spray all the clothes 3 in the washing cylinder 2 in the axial direction, so that the water sprayed on the clothes 3 is ensured to permeate and separate from the clothes 3 quickly and dirty is brought out.

In some embodiments, the bleaching comprises:

a. the washing drum 2 is dehydrated for a first preset time at a third rotating speed;

b. spraying the clothes 3 in the washing cylinder 2 for a second preset time at a fourth rotating speed by the washing cylinder 2; simultaneously starting drainage;

c. detecting the conductivity of the residual water in the washing cylinder 2;

d. when the conductivity of the residual water is less than or equal to a preset value, the washing drum 2 is dewatered at a fifth rotating speed.

Draining water after the main washing is finished, rinsing and dehydrating the clothes 3 to remove residues such as detergent, and sequentially realizing the dehydration, spraying and re-dehydration processes by regulating and controlling the rotating speed of the washing drum 2; and detecting the conductivity of the residual water after spraying between spraying and re-dewatering so as to determine re-dewatering; the control is convenient and easy.

In some embodiments, when the conductivity of the residual water is greater than a preset value, repeating steps b and c.

When the conductivity of the residual water is greater than the preset value, it indicates that the detergent remains much, and it is necessary to spray again to wash and remove the detergent in the laundry 3.

In some embodiments, the number of showers in step b is set as n, the number of showers in the preset rinsing of the washing machine is set as K, n > K is satisfied, and the washing drum 2 is dehydrated at the fifth rotation speed. Preferably, K is set to 1-6. More preferably, K is set to 2-4.

K is generally determined by the functions of the washing machine, when the washing machine sprays for n times, if n is less than or equal to K, the conductivity of residual water is detected to be less than a preset value, and the washing machine can be turned into a fifth rotating speed to start a dehydration step; otherwise, until n is larger than K, dewatering at the fifth rotating speed. In some embodiments, the second rotational speed < the fourth rotational speed < the first rotational speed < the third rotational speed < the fifth rotational speed.

Setting the second rotating speed, the fourth rotating speed, the first rotating speed, the third rotating speed and the fifth rotating speed as V2, V4, V1, V3 and V5 in sequence, wherein V2 is less than V4 and less than or equal to V1 and less than or equal to V3 and less than or equal to V5, preferably V3= V5, wherein the optional range of V1 is 300-1000 rpm, preferably 500-800 rpm; v4 can be selected within the range of 200-800 rpm, preferably 300-500 rpm; the optional range of V3 and V5 is 600-1200 rpm, preferably 800-1000 rpm; v2 can be selected in the range from 0 to 50 rpm, preferably 0 rpm, i.e.preferably the drum is stopped.

The running time T1 at V1 can be selected from 0.5 to 5 minutes, preferably from 0.5 to 2 minutes; the running time T2 under V3 can be 0.5-3 minutes, preferably 1-2 minutes; the running time T3 at V4 can be selected from 1 to 8 minutes, preferably from 3 to 5 minutes; the running time T4 at V5 can be selected from 1 to 6 minutes, preferably from 1 to 3 minutes; the run time T5 at V4 can be from 0.5 to 5 minutes, preferably from 1 to 3 minutes.

When the clothes 3 begin to float and take off, the clothes 3 are leveled up and then run at a speed increasing to a rotating speed V3, and the residual washing water of the clothes 3 is taken off within T2 time of the rotating speed. Then, the speed is reduced to a rotating speed V4 for spraying and rinsing for T3 time, and the spraying water flow permeates the clothes 3 and takes away the washing water containing residual stains such as detergent. And after the spray rinsing is carried out for T3 time, detecting whether the stored water at the bottom of the outer barrel meets the requirement of clean rinsing. Preferably, the conductivity I in the stored water can be detected, the detected conductivity value I is compared with a preset value I1, if I is less than or equal to I1, the washing machine can be accelerated to a rotating speed V5 for dewatering for T4 time for final spin-drying, and the whole washing work is finished after shaking and dispersing; if I > I1, judging the situation of the rinsing times n, if n is less than or equal to K, continuing to spray and rinse at the stage of T3 by spraying at the rotating speed V4 until the rinsing situation meets the requirements or the spraying times reach the set maximum times, namely n > K. Wherein the K value is optionally 1-6, preferably 2-4.
