[0037] Refer to the attached Figure 1 , Figure 1 It is a schematic diagram of the main steps of a control method for a washing machine according to an embodiment of the present invention. As Figure 1 shown, the control method for the washing machine in the embodiment of the present invention mainly includes the following steps S101 - step S103.

[0038] Step S101: Obtain the mass and initial cleanliness of the laundry residues in the inner drum of the washing machine.

[0039] In this embodiment, the mass and initial cleanliness of the laundry residues in the inner drum of the washing machine are obtained. Among them, the initial cleanliness is the cleanliness in the inner drum of a brand-new washing machine before use or after the washing machine performs self-cleaning.

[0040] In one embodiment, the initial cleanliness may be 100.

[0041] In one embodiment, the mass of the laundry residues can be obtained according to steps S1011 - step S1012:

[0042] Step S1011: Obtain the first mass of the clothing drying residue and the second mass of the clothing washing residue;

[0043] In one embodiment, the first mass is obtained according to formula (1):

[0044] B = b1×n1 + b2×n2 + b3×n3 + b4×n4 (1)

[0045] Wherein, B is the first mass, b1 is the mass of the dried clothing in the first quarter, b2 is the mass of the dried clothing in the second quarter, b3 is the mass of the dried clothing in the third quarter, b4 is the mass of the washed clothing in the fourth quarter, n1 is the drying residue coefficient in the first quarter, n2 is the drying residue coefficient in the second quarter, n3 is the drying residue coefficient in the third quarter, n4 is the drying residue coefficient in the fourth quarter. Since lint is likely to fall off the wool knitted clothing during the drying process in the washing machine, the number of times of drying the wool knitted clothing in the first quarter and the fourth quarter is similar, and the number of times of drying the wool knitted clothing in the first quarter and the fourth quarter is more than that in the second quarter and the third quarter, and the number of times of drying the wool knitted clothing in the second quarter is greater than that in the third quarter. Therefore, the magnitude relationship of the drying residue coefficients in each quarter is set as the drying residue coefficient in the first quarter is equal to the drying residue coefficient in the fourth quarter, which is greater than the drying residue coefficient in the second quarter, which is greater than the drying residue coefficient in the third quarter.

[0046] In one embodiment, on the premise that the drying residue coefficient in the first quarter is equal to the drying residue coefficient in the fourth quarter, which is greater than the drying residue coefficient in the second quarter, which is greater than the drying residue coefficient in the third quarter, the drying residue coefficient in the first quarter and the fourth quarter can be set to two percent, the drying residue coefficient in the second quarter can be set to one point five percent, and the drying residue coefficient in the third quarter can be set to one percent.

[0047] In one embodiment, the second mass is obtained according to formula (2):

[0048] A = a1×m1 + a2×m2 + a3×m3 + a4×m4 (2)

[0049] Wherein, A is the second quality, a1 is the quality of the laundry washed in the first quarter, a2 is the quality of the laundry washed in the second quarter, a3 is the quality of the laundry washed in the third quarter, a4 is the quality of the laundry washed in the fourth quarter, m1 is the washing residue coefficient in the first quarter, m2 is the washing residue coefficient in the second quarter, m3 is the washing residue coefficient in the third quarter, m4 is the washing residue coefficient in the fourth quarter. Since lint is likely to fall off during the washing of wool knitted garments in the washing machine, the number of times of washing wool knitted garments in the first quarter and the fourth quarter is similar, and the number of times of washing wool knitted garments in the first quarter and the fourth quarter is more than that in the second quarter and the third quarter, and the number of times of washing wool knitted garments in the second quarter is greater than that in the third quarter. Therefore, the magnitude relationship of the washing residue coefficients in each quarter is set as the washing residue coefficient in the first quarter is equal to the washing residue coefficient in the fourth quarter, which is greater than the washing residue coefficient in the second quarter, which is greater than the washing residue coefficient in the third quarter.

[0050] In one embodiment, on the premise that the washing residue coefficient in the first quarter is equal to the washing residue coefficient in the fourth quarter, which is greater than the washing residue coefficient in the second quarter, which is greater than the washing residue coefficient in the third quarter, the washing residue coefficient in the first quarter and the washing residue coefficient in the fourth quarter can be set to 2%, the washing residue coefficient in the second quarter can be set to 1.5%, and the washing residue coefficient in the third quarter can be set to 1%.

[0051] Step S1012: Obtain the mass of the laundry residue based on the first quality and the second quality.

[0052] In this embodiment, the mass of the laundry residue is obtained according to the first quality and the second quality.

[0053] In one embodiment, the mass of the laundry residue is obtained according to formula (3):

[0054] C = A + B (3)

[0055] Wherein, C is the mass of the laundry residue, A is the second quality, and B is the first quality.

[0056] Step S102: Obtain the current cleanliness inside the inner drum of the washing machine based on the mass of the laundry residue and the initial cleanliness.

[0057] In this embodiment, the current cleanliness inside the inner drum of the washing machine is obtained according to the mass of the laundry residue and the initial cleanliness.

[0058] In one embodiment, the current cleanliness inside the inner drum of the washing machine is obtained according to formula (4):

[0059] D = Q - C (4)

[0060] Wherein, D is the current cleanliness, Q is the initial cleanliness, and C is the mass of the clothing residue.

[0061] Step S103: Selectively control the washing machine to perform self-cleaning based on the current cleanliness.

[0062] In this embodiment, the operation of the self-cleaning program of the washing machine is selectively controlled according to the current cleanliness.

[0063] In one embodiment, step S103 may further include step S1031:

[0064] Step S1031: When the current cleanliness is less than or equal to a preset threshold, control the washing machine to perform self-cleaning at a preset time point.

[0065] In this embodiment, when the current cleanliness is less than or equal to a preset threshold, control the washing machine to start the self-cleaning program at a preset time point. Wherein, when the preset threshold is less than the initial cleanliness, those skilled in the art can customize the preset threshold according to actual usage needs.

[0066] In one embodiment, the user can customize the preset time point according to actual usage needs. For example, the preset time point can be set to one hour after the washing machine finishes the drying program or the washing program.

[0067] Based on the above steps S101 - S103, the control method of the washing machine according to the present invention includes: obtaining the mass of the clothing residue and the initial cleanliness in the inner drum of the washing machine, obtaining the current cleanliness in the inner drum of the washing machine based on the mass of the clothing residue and the initial cleanliness, and selectively controlling the washing machine to perform self-cleaning based on the current cleanliness. Through the above configuration, the present invention first obtains the mass of the clothing residue and the initial cleanliness in the inner drum of the washing machine, then determines the current cleanliness in the inner drum of the washing machine through the obtained mass of the clothing residue and the initial cleanliness in the inner drum of the washing machine, and automatically performs the inner drum cleaning through the current cleanliness, which can realize the autonomous judgment of the cleanliness in the inner drum of the washing machine and automatically perform the inner drum cleaning to improve the user experience of using the washing machine.

[0068] In one embodiment, reference may be made to the attached Figure 2 , Figure 2 is a schematic diagram of the main step flow of the control method of a washing machine according to an embodiment of the present invention. As Figure 2 shown, the control method of the washing machine may include the following steps S201 to S205.

[0069] Step S201: Obtain the first mass of the clothing drying residue and the second mass of the clothing washing residue.

[0070] In this embodiment, the method described in step S201 is similar to the method described in the foregoing step S1011. For the sake of simplicity, it will not be elaborated here.

[0071] Step S202: Based on the first quality and the second quality, obtain the mass of the clothing residue.

[0072] In this embodiment, the method described in step S202 is similar to the method described in the foregoing step S1012. For the sake of simplicity, it will not be elaborated here.
