[0045] Among existing technologies, some have proposed scanning the outer surface of a washing tub with light to determine its light transmittance and thereby determine the degree of dirtiness within the tub. However, this approach is complex and time-consuming. Others have proposed determining whether to clean the tub based on the cumulative total wash time or the cumulative number of washes. However, this approach fails to fully consider the impact of wash water quality parameters on the amount of residual dirt, resulting in inaccurate dirt calculations and, consequently, premature or delayed cleaning of the tub by the user.

[0046] The present invention creatively provides a cleaning reminder method for a washing machine, which includes a washing tub. The dirt residue coefficient is determined based on the quality parameters of the washing water discharged from the washing tub after each wash, and the amount of dirt residue in the washing tub after each wash is obtained by combining the change in the total weight of the clothes and the washing water before and after each wash. The accumulated dirt residue in the washing tub is then accumulated to obtain the accumulated dirt residue; the accumulated dirt residue is compared with the preset dirt residue, and then it is determined whether to remind the user to clean the washing tub; considering the influence of the quality parameters of the washing water on the dirt residue, the calculation method of the dirt residue in the washing tub is optimized, the calculation is accurate, the washing tub is cleaned in time, the clothes are washed thoroughly, and the health of the clothes after washing is guaranteed.

[0047] like Figure 1 As shown, this embodiment provides a cleaning reminder method for a washing machine, the washing machine including a washing tub, and the cleaning reminder method includes:

[0048] S1. Calculate the amount of dirt accumulated in the washing tub A; the amount of dirt accumulated in the washing tub Wherein, Mi is the change in the total weight of the clothes and washing water before and after the i-th wash of the washing machine; ki is the dirt residual coefficient in the washing tub after the i-th wash of the washing machine, and ki is the weight coefficient related to the quality parameter of the washing water discharged from the washing tub; n is the number of washes of the washing machine, and n is a natural number greater than or equal to 1;

[0049] S2. Compare the accumulated residual amount A of dirt in the washing tub with the preset residual amount A0 of dirt to determine whether to remind the user to clean the washing tub.

[0050] Considering that the quality parameters of the washing water discharged from the washing tub after each wash are different, the amount of dirt residue in the washing tub is different. Therefore, the dirt residue coefficient is determined according to the quality parameters of the washing water discharged from the washing tub after each wash. Combined with the change in the total weight of the clothes and washing water before and after each wash, the amount of dirt residue in the washing tub after each wash is determined, and then the accumulated dirt residue is obtained; the calculation process of the dirt residue in the washing tub is simplified, the calculation is accurate, the washing tub is cleaned in time, the clothes are washed thoroughly, the washing efficiency is guaranteed, and the user experience is improved; it avoids the problem of frequent cleaning of the washing tub causing accelerated wear of the washing machine parts, or not cleaning the washing tub for too long causing bacteria to grow in the washing tub.

[0051] Furthermore, before step S1, the following steps are also included:

[0052] Get the total weight Mi of the clothes in the washing tub and the added washing water before the i-th wash f ;

[0053] Get the total weight Mi of the clothes in the washing tub and the discharged washing water after the i-th wash b ;

[0054] According to Mi f and Mi b , we get Mi=Mi f -Mi b .

[0055] Before washing, the weight of the clothes in the washing tub can be measured by a pressure sensor, and the flow rate of the added washing water can be detected, thereby obtaining the weight of the added washing water, and thus the total weight of the clothes in the washing tub and the added washing water can be obtained;

[0056] After washing, the weight of the clothes in the washing tub can be measured by a pressure sensor, and the flow rate of the discharged washing water can be detected, thereby obtaining the weight of the discharged washing water, and thus the total weight of the clothes in the washing tub and the discharged washing water can be obtained;

[0057] During the washing process, old dirt on the walls of the washing tub falls into the wash water and is drained away with it, while new dirt adheres to the walls of the washing tub. Therefore, by calculating the change in the total weight of the clothes and wash water before and after washing, we can roughly estimate the change in the amount of dirt remaining in the washing tub.

[0058] To address the problem of inaccurate calculation of the amount of dirt remaining in the washing tub after each wash, this embodiment proposes to calculate the amount of dirt remaining in the washing tub after each wash based on the dirt remaining coefficient in the washing tub and the change in the total weight of the clothes and washing water before and after washing. Specifically, before step S1, the following steps are further included:

[0059] Obtain the quality parameters of the washing water discharged from the washing tub after the i-th washing;

[0060] Determine whether the quality parameters are within the preset quality parameter range;

[0061] Determine the dirt residual coefficient ki based on the judgment result of whether the quality parameter is within the preset quality parameter range;

[0062] The quality parameters of the washing water discharged from the washing tub include the temperature of the washing water and / or the turbidity of the washing water and / or the viscosity of the washing water and / or the impurity content of the washing water.

[0063] When the washing water is hot and turbid, or when the viscosity and impurity content are high, impurities in the washing water are more likely to adhere to the walls of the washing tub. Therefore, the quality parameters of the washing water are key to influencing the amount of residual dirt in the washing tub. Different washing water quality parameters result in different residual dirt coefficients, and each wash results in a different residual dirt coefficient. This further improves the calculation accuracy of the accumulated residual dirt, allowing accurate judgment on whether the washing tub needs to be cleaned, thereby ensuring the cleanliness of the washing tub.

[0064] Considering that when the quality parameters of the washing water are within the preset quality parameter range, the difference in the quality parameters has little effect on the amount of residual dirt in the washing tub; this embodiment proposes that the residual dirt coefficient ki is determined based on the result of determining whether the quality parameters are within the preset quality parameter range, including:

[0065] When the quality parameter is within the preset quality parameter range, the dirt residual coefficient ki=ti+pi is determined; wherein ti is the temperature of the washing water discharged from the washing tub after the i-th wash of the washing machine, and pi is the turbidity of the washing water discharged from the washing tub after the i-th wash of the washing machine;

[0066] When the quality parameter is not within the preset quality parameter range, determining the dirt residual coefficient ki=k0, and k0=t0+p0; wherein k0 is the preset dirt residual coefficient, t0 is the preset temperature of the washing water discharged from the washing tub after each wash of the washing machine, and p0 is the preset turbidity of the washing water discharged from the washing tub after each wash of the washing machine;

[0067] According to the different ranges of the quality parameters of the washing water, the calculation method of the dirt residual coefficient is different, which improves the calculation accuracy of the dirt residual coefficient; further accurately grasps the residual amount of dirt in the washing tub, and simplifies the calculation process of the residual amount of dirt in the washing tub; on the one hand, the residual amount of dirt in the washing tub is obtained in a timely and accurate manner, and the washing tub is cleaned in time, which improves the user experience and avoids frequent cleaning of the washing tub causing accelerated wear of the washing machine parts, or not cleaning the washing tub for too long causing bacteria to grow in the washing tub; on the other hand, according to the different quality coefficients of the washing water, the type of dirt, the volume of a single dirt and the coverage area of ​​multiple dirt can be judged, and then the corresponding cleaning method can be selected to clean the washing tub, thereby improving the cleaning effect.

[0068] In addition, the residual dirt coefficient ki in the washing tub after the i-th wash of the washing machine is also related to the surface area and surface hydrophobicity of the washing tub. When the flow rate of washing water added to the washing tub is large and the surface area of ​​the washing tub is large, more dirt can adhere to the wall of the washing tub; when the surface hydrophobicity of the washing tub wall is small, more dirt can adhere to the wall of the washing tub.

[0069] To address the problem of inaccurate calculation of the preset residual amount of dirt, this embodiment proposes a method for determining the preset residual amount of dirt A0, including:

[0070] Obtaining a preset change M0 in the total weight of the clothes and washing water before and after each wash;

[0071] Determine the preset number of wash cycles n0 for the washing machine;

[0072] According to M0, k0 and n0, the preset residual amount of dirt A0=k0*n0*M0 is determined.

[0073] Furthermore, the cleaning reminder method also includes:

[0074] When A<A0, it indicates that the washing tub is clean and does not need to be cleaned, so the user is not reminded to clean the washing tub;

[0075] When A≥A0, it indicates that the cleanliness of the washing tub is low and needs to be cleaned, so the user is reminded to clean the washing tub; specifically, the information reminding the user to clean the washing tub includes a voice reminder to the user that the washing tub needs to be cleaned, and also reminds the user of the type of dirt, the location of the dirt, and the corresponding method for cleaning the dirt.

[0076] After each cleaning is completed, the parameters before the cleaning are reset to zero; specifically, the cleaning reminder method also includes:

[0077] After cleaning the washing tub, the accumulated residual dirt amount A in the washing tub, the change in the total weight of the clothes and washing water before and after the i-th wash Mi, and the residual dirt coefficient ki in the washing tub after the i-th wash are all reset to zero.

[0078] This embodiment further provides a control device for the cleaning reminder method of any one of the above-mentioned washing machines, comprising:

[0079] A monitoring module, used to detect the quality parameters of the washing water discharged from the washing tub;

[0080] A calculation module is used to calculate the change in the total weight of the clothes and washing water before and after each wash and the amount of accumulated dirt remaining in the washing tub;

[0081] A storage module, used for storing a preset residual amount of dirt in the washing tub;

[0082] The analysis module is used to compare the accumulated residual amount of dirt in the washing tub with the preset residual amount of dirt, and determine whether to remind the user to clean the washing tub.

[0083] This embodiment also proposes a non-transitory computer-readable storage medium on which program instructions are stored. When the program instructions are executed by one or more processors, the one or more processors are used to implement the cleaning reminder method for the washing machine according to any of the above items.

[0084] This embodiment further provides a washing machine, comprising the control device of the above-mentioned washing machine cleaning reminder method or the above-mentioned non-transitory computer-readable storage medium.
