The control method of the embodiment of the invention determines that the drum washing machine enters a main washing stage, and controls the drum washing machine to wash based on the first control parameter corresponding to the type of the clothes to be washed, so that a water film with a set thickness is formed between the inner wall surface of the inner drum of the drum washing machine and the clothes to be washed, the clothes to be washed in the inner drum can be separated from the inner wall of the inner drum by the water film, the clothes to be washed are supported by the pressure of the water film, and the direct friction between the clothes to be washed and the inner wall of the inner drum is avoided, so that the wear to the clothes to be washed is reduced.
In the main washing stage, the rotation speed of the inner drum is controlled, the clothes to be washed and water ascend along with the inner drum, water is sprayed to the clothes and the inner drum in the process, a water film is generated to separate the clothes from the inner wall of the inner drum by utilizing the relative speed difference between the clothes and the inner drum, and the clothes are supported by the pressure generated by the water film. The water film fills the gap between the clothes and the inner wall of the inner drum, so that the clothes are prevented from directly rubbing the inner drum, and the damage to the clothes is reduced.
In practical application, the thickness d of the water film has a correlation with the inner cylinder rotation speed R, the water level W and the water injection amount V, i.e., d ═ f (R, W, V). The higher the rotation speed R is, the smaller d is, the higher W water level is, the larger the water spraying amount V is, and the larger d is.
The embodiment of the invention determines the corresponding clothes type according to the fiber surface characteristics and the processing technology of the clothes. For example, on the one hand, silk, wool, cotton, hemp, chemical fiber, etc. have different fiber surface properties; on the other hand, different flatness of the garment surface is created by different processing techniques, such as weaving, knitting, or plain or twill. When clothes are washed, a water film with proper thickness is formed between the surface of the fabric and the inner wall of the inner cylinder according to different clothes characteristics, so that certain cleaning performance is ensured, the clothes can be well cared, and abrasion is reduced.
In one embodiment, when the kind of the clothes to be washed is wool knitted fabric, the set thickness of the water film is 5 to 10 mm.
In one embodiment, when the type of the clothes to be washed is embroidered clothes, the set thickness of the water film is 8-12 mm.
In one embodiment, when the type of the clothes to be washed is chemical fiber woven fabric, the set thickness of the water film is 0.5 to 2 mm.
In one embodiment, when the type of the clothes to be washed is a woven cotton/linen fabric, the set thickness of the water film is 0.5-7 mm.
According to the embodiment of the invention, the clothes type of the clothes to be washed is identified, the corresponding first control parameter is determined according to the corresponding clothes type, so that the drum washing machine is controlled to wash, the corresponding water film control can be realized according to different clothes types, and the optimal clothes care effect is achieved.
Since the inner wall surface of the inner drum and the surface of the laundry to be washed are spaced by the water film with the set thickness when the first control parameter is adopted to control the drum washing machine to wash, the laundry is facilitated to be cared, but the cleaning efficiency of the laundry may be affected due to the reduction of the friction force on the surface of the laundry, in an embodiment, the method further comprises:
in the washing stage, controlling the drum washing machine to wash based on a second control parameter;
the second control parameter is used for controlling the thickness of the anhydrous film or the water film between the inner wall surface of the inner drum of the drum washing machine and the clothes to be washed to be smaller than the set thickness.
In an embodiment, the second control parameter may be obtained by adjusting a corresponding value of the first control parameter, for example, the second control parameter may include at least one of: and adjusting the water level of the inner cylinder in the first control parameter to be small, adjusting the rotating speed of the inner cylinder in the first control parameter to be large, and adjusting the water spraying action beat in the first control parameter to reduce the water spraying amount in the water spraying period, and adjusting the inner cylinder action beat in the first control parameter to reduce the rotation time of the inner cylinder in the rotation period.
In one embodiment, in the washing stage, the drum washing machine is controlled to operate alternately based on the first control parameter and the second control parameter, or after the drum washing machine is controlled to operate for a first set time period based on the first control parameter, the drum washing machine is controlled to operate for a second set time period based on the second control parameter. Therefore, the clothes washing machine is beneficial to reducing the abrasion of clothes in the washing process and ensuring the cleaning effect of the clothes.
In one embodiment, the inner cylinder of the drum washing machine is a non-porous inner cylinder, that is, no water permeable holes are arranged on the wall body of the inner cylinder, and the drainage during the dehydration is realized by improving the structure of the opening of the inner cylinder. For the imperforate inner barrel, since the wall body of the inner barrel is not provided with the water permeable holes, the water film can be kept for a long time, and accordingly, the drum washing machine can omit the water spraying mechanism shown in fig. 3 or fig. 4. In an embodiment, the first control parameter comprises: inner tube water level, inner tube rotational speed and inner tube action beat, based on first control parameter control drum type washing machine washes, include:
determining the water level in the drum washing machine as the water level of the inner drum, and controlling the drum washing machine to operate at the rotation speed of the inner drum according to the action beat of the inner drum;
the inner cylinder action beat comprises the rotation time length and the rotation stopping time length of the inner cylinder in one rotation period.
According to the embodiment of the invention, a water spraying mechanism is not required to be arranged on the drum washing machine, and the control of the thickness of the water film can be realized by controlling the rotating speed of the inner cylinder and the action beat of the inner cylinder. In addition, the corresponding first control parameter is determined according to the corresponding clothes type by identifying the clothes type of the clothes to be washed so as to control the drum washing machine to wash, so that the corresponding water film control can be realized according to different clothes types, and the optimal clothes care effect is achieved.
