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 method for controlling a washing machine is provided. The washing machine measures the pollution index of the washing tub in a single washing by taking the time interval between adjacent washings, the washing program selected for each washing and the water 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 a single washing cycle cause the washing tub to be dirty in different degrees. For example, the high temperature generated during the drying process will reduce the survival probability of microorganisms in the washing tub, so that the degree of contamination is reduced. Relatively, rinsing When the dirt and bacteria in the clothes enter the washing water containing nitrogen and phosphine elements, the pollutio...

Embodiment 2

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

[0092] In this 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 temperature T of the water body in the washing tub in the i-th washing i and the water retention time t in the washing tub i Carry out double integration, the integration result affects the water quality coefficient A i .

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

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 wash T' i Indicates the temperature coefficient that the selected washing temperature of the i-th washing affects 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 set Different coefficients are set to characterize its influence on the pollution degree.

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

Abstract

The invention discloses a washing machine control method. The washing machine measures and calculates the pollution index of the washing bucket in a single washing at least with the water quality as the influencing factor, and reminds the user to run self-cleaning when the accumulated pollution index of multiple washings reaches or exceeds a critical value. program. The control method provided by this application converts the operating parameters and data of the washing machine into coefficients that affect the degree of dirtiness of the washing tub, and at the same time introduces the coefficient of influent water quality that affects the degree of pollution of the washing tub, and incorporates water hardness, water body temperature and water quality. The effect of retention time on the water quality coefficient is logical and reasonable, and it can accurately reflect the contribution of water quality to the pollution of the washing bucket, which is suitable for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of clothes treatment, and in particular relates to a control method of a washing machine. Background technique [0002] According to research statistics, the dirt in the washing tub of the washing machine mainly comes from the microorganisms (such as Pseudomonas aeruginosa, Escherichia coli, mold, etc.) in the gaps between the clothes fibers and the surface of the clothes, and the humid environment in the washing tub of the washing machine is generated when the air is not ventilated. Unpleasant smell. These problems bring about secondary pollution in the subsequent washing of clothes, which is harmful to the health of users. [0003] Most of the existing washing machines themselves have the self-cleaning function of the washing tub, which can be sterilized and disinfected at high temperature, and regular use and cleaning can effectively reduce secondary pollution. However, according to big data statistics,...
