Problems solved by technology

However, according to big data statistics, the frequency of self-cleaning of the washing bucket is very low, indicating that most users do not pay enough attention to the secondary pollution of the washing bucket and do not understand the self-cleaning function
[0004] At present, washing machines often use the accumulated water turbidity of each washing or the cumulative operation cycle to measure the pollution degree of the washing bucket. However, other factors are ignored, such as the inability to accurately reflect the hardness and water temperature of the incoming water, which causes scale to pollute the washing bucket.

Embodiment 1

[0063] In this embodiment, a washing machine control method is provided. The washing machine measures the pollution index of the washing tub in a single washing with the time interval between adjacent washings, the washing program selected for each washing, and the quality of the influent water as influencing factors. When the cumulative pollution index of multiple washings reaches or exceeds the critical value, the user is reminded to run the self-cleaning program.

[0064] In this embodiment, when the washing machine is in use, different programs in the separate washing cycle cause the degree of dirtyness of the washing tub to be different. For example, the high temperature generated in the drying process will reduce the survival probability of microorganisms in the washing tub, so that the degree of pollution is reduced. Relatively, rinsing When the dirt and bacteria in the clothes enter the washing water containing nitrogen and phosphine elements, the pollution degree of th...

Embodiment 2

[0091] The difference between this embodiment and embodiment 1 is:

[0092] In the present embodiment, the water quality coefficient is expressed as A i =D i ×∫∫h(T i ,t i )dT i dt i (i≥1), where ∫∫h(T i ,t i )dT i dt i Indicates the water temperature T in the washing tub for the i-th washing i and the water retention time in the washing bucket t i Carry out double integration, and the integration result affects the water quality coefficient A i .

[0093] In this embodiment, after different modeling results, the factors that affect the water quality coefficient A come from the water hardness D, the water temperature T and the residence time t of the water body in the washing tub, regardless of the function between the water temperature T and the residence time t The relationship between the water temperature T and the residence time t of the water body in the washing tub is double-integrated and then multiplied by the water quality hardness D, which reduces the co...

Embodiment 3

[0108] The difference between this embodiment and embodiment 1 or 2 is:

[0109] In this embodiment, the washing temperature of the washing machine can be adjusted, and the cumulative pollution index of the washing tub in each washing T' i Indicates the temperature coefficient of the selected washing temperature for the i-th washing affecting the pollution degree of the washing tub.

[0110] In this embodiment, the washing temperature will affect the molecular activity and the degree of bacterial growth. Therefore, the temperature coefficient T' is set on the basis of the program coefficient P and the cumulative interval coefficient K, and based on theoretical analysis and experimental verification, according to different washing temperatures. Different coefficients are set to characterize its influence on pollution degree.

[0111] In this embodiment, the program coefficient P is obtained by accumulating coefficients corresponding to each program in the washing process, th...

Abstract

The invention discloses a washing machine control method. The washing machine measures the pollution index of a washing barrel in single washing at least with inflow water quality as an influence factor, and a user is reminded to run a self-cleaning program when the accumulated pollution index of multiple times of washing reaches or exceeds a threshold value. According to the control method provided by the invention, the running parameters and the data of the washing machine are converted into coefficients influencing the dirty degree of the washing barrel, meanwhile, an inflow water quality coefficient influencing the pollution degree of the washing barrel is introduced, the influence of the water quality hardness, the water temperature and the water retention time on the water quality coefficient is included, the method is reasonable in logic, the contribution of the water quality to the pollution of the washing barrel can be accurately reflected, and the washing machine control method is suitable for being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of clothes treatment, and in particular relates to a washing machine control method. Background technique [0002] According to research statistics, the dirt in the washing bucket of the washing machine mainly comes from the microorganisms (such as Pseudomonas aeruginosa, Escherichia coli, mold, etc.) smell. These problems have brought secondary pollution during the subsequent washing of clothes, causing harm to the health of users. [0003] Most of the existing washing machines have the self-cleaning function of the washing tub, which can be sterilized at high temperature, and regular use and cleaning can effectively reduce secondary pollution. However, according to big data statistics, the frequency of users using the self-cleaning bucket is very low, indicating that most users do not pay enough attention to the secondary pollution of the washing bucket and do not understand the self-cleaning function. ...
