Accordingly, there is provided a control method of a washing machine in the present embodiment, which is different from the control method of the existing general washing apparatus:
the washing machine does not need a user to set a washing program, but controls the whole washing process according to the turbidity information and the friction information detected by the turbidity detection device, the washing machine comprises an automatic washing mode, and after the user selects the mode, the washing machine automatically controls and executes the washing process: the washing machine firstly controls the impeller and/or the inner barrel to rotate, drives the turbidity detection device to relatively move with clothes to detect the friction force of the clothes, and automatically selects a matched washing program according to the friction force; and then the washing machine executes the washing program, in the washing process, the washing machine adjusts washing parameters according to the friction force information and the turbidity information detected by the turbidity detection device, if the turbidity is detected to be large, the water level parameter is reduced, the clothes are washed firstly by less water, the waste of water resources is prevented, and finally the washing machine controls the washing machine to keep the washing stage/rinsing stage or end the washing stage/rinsing stage according to the turbidity information detected by the turbidity detection device. Therefore, the washing machine can be matched with the turbidity detection device to automatically control the whole washing process, and the user is not required to participate in the indication.
Wherein, based on turbidity detection device has the function of detecting frictional force, this washing machine has following control method:
the washing machine drives the laundry in the washing chamber to move, and during the movement of the laundry, frictional force information applied to the turbidity detecting device placed in the washing chamber by the laundry is tested.
Preferably, the washing machine determines a suitable washing parameter based on the detected friction information;
in the scheme, the clothes are easier to clean as the friction force is larger, but if the friction force is too large, the clothes are possibly damaged, and the washing machine selects proper washing parameters according to the detected friction force information, so that the washing effect of the clothes is improved on the premise of ensuring that the clothes are not damaged.
The washing machine selects a proper washing program according to the washing parameters, or adjusts the washing parameters in the currently executed washing program according to the washing parameters.
In the above scheme, the washing machine selects a corresponding washing program according to the appropriate washing parameters and controls the washing machine to execute the washing program, in addition, when the washing machine is already in the process of executing the washing program, the washing machine still detects friction force information of clothes, determines the appropriate washing parameters according to the friction force, and then adjusts the washing parameters in the current washing program.

in the scheme, the water level parameter and the washing strength parameter both influence the friction force born by the clothes, and the friction force born by the clothes can be regulated by regulating the water level parameter and the washing strength parameter.
The water level is high, so that the clothes can be dispersed, and the driving force exerted by the pulsator is buffered, so that the washing strength is reduced, and the friction force born by the clothes is reduced.
The washing machine selects a proper washing program according to the water level parameter and/or the washing intensity parameter, or the washing machine adjusts the water level parameter or the washing intensity parameter in the currently executed washing program according to the water level parameter and/or the washing intensity parameter.
Preferably, the greater the friction force of the laundry detected by the turbidity detecting device, the greater the washing machine control water level parameter and/or the smaller the washing strength parameter.
In the scheme, in the actual control process, the greater the friction force of the clothes detected by the turbidity detection device is, the higher the control water level is and/or the washing strength parameter is reduced, so that the friction force of the clothes is effectively reduced, and the clothes are prevented from being damaged.
Preferably, the determining of the water level parameter by the washing machine according to the detected friction force information includes detecting friction force information of laundry before water inflow by the washing machine to determine the water level parameter, and the washing machine selects an appropriate washing program or adjusts the water level parameter of the selected washing program according to the determined water level parameter.
Preferably, the detecting friction information of the laundry before water inflow to determine the water level parameter includes: before water enters the washing machine, driving clothes to move so as to detect friction force information of the clothes, judging the water content of the clothes according to the friction force information, and determining a water level parameter according to the water content of the clothes;
in the above scheme, because the clothes put into the washing chamber may be wet clothes, if a user firstly washes some clothes manually and then places the clothes in the washing chamber of the washing machine, then the water content of the clothes is larger, the friction force of the clothes detected naturally is also larger, so that the water level parameter in the matched washing parameters is larger, and then the water inflow in the washing machine is larger, water resources are wasted and the required washing effect is difficult to achieve by adding the wet clothes.
Wherein the larger the water content of the laundry, the smaller the control water level parameter;
in addition, the washing machine judges the water content of the laundry according to the variation of the friction of the laundry: in the process of driving the clothes to move, the larger the friction variation of the clothes is, the larger the water content of the clothes is judged.
In the scheme, in the process of driving the clothes to move before water inflow, water on the clothes can be separated under the action of centrifugal force, so that the friction force applied to the turbidity detection device by the clothes is correspondingly reduced, and when the change amount of the friction force of the clothes is detected to be larger, the water content of the clothes on the water surface is larger.
Preferably, the washing machine also adjusts the water level parameter in real time during the washing process: the turbidity detection device detects friction force information of clothes in a washing process to determine a water level parameter, and the water level of the washing machine is adjusted in real time according to the water level parameter, wherein the higher the friction force of the clothes is, the higher the water level of the washing machine is adjusted.
Preferably, the determining of the washing strength parameter by the washing machine according to the detected friction force information includes: the washing machine judges the material information of the clothes according to the friction force information, and when the material of the clothes is judged to be lighter, the determined washing strength parameter is smaller;
preferably, the friction force in different sections of the clothes corresponds to different material information, the washing machine judges the material information of the clothes according to the section where the detected friction force is located, and corresponding washing strength parameters are determined according to the material information of the clothes.
