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. The impact of the degree of pollution of the barrel, while ignoring other factors, resulting in the problem that the degree of pollution of the barrel cannot be accurately reflected; at the same time, this type of method also requires additional detection devices, which virtually increases the cost of the washing machine

Embodiment 1

[0054] In this example, if figure 1 As shown, a washing machine control method is provided. The washing machine uses the time interval between adjacent washings and the washing program selected for each washing as the influencing factors to measure the pollution index of the washing tub in a single washing. When the accumulated pollution of multiple washings When the index accumulation reaches or exceeds the critical value, the user is reminded to run the self-cleaning program.

[0055] 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...

Embodiment 2

[0076] The difference between this embodiment and embodiment 1 is:

[0077] In this embodiment, the cumulative interval coefficient Among them, k i Indicates the interval coefficient of each washing time interval before the i-th washing that affects the pollution degree of the washing bucket during the i-th wash, and the interval coefficient k of the first wash when i=1 in the statistical cycle 1 =1, the interval coefficient k of the first wash when i>1 1 =0.

[0078] In this embodiment, the washing machine records the time intervals of each washing cycle in the statistical cycle, and when determining the cumulative interval coefficient of a certain washing cycle, it is necessary to add the interval coefficients of each washing cycle counted before this washing at the same time, in order to The present invention is better described, for example as follows:

[0079]In the first washing, since there is no interval for this washing, but considering that the program coefficie...

Embodiment 3

[0086] The difference between this embodiment and embodiment 1 or 2 is:

[0087] In this embodiment, the washing temperature of the washing machine can be adjusted, so the pollution index of the washing tub in a single washing is s=P×K×T, where T represents the influence of the washing temperature selected in the single washing on the pollution degree of the washing tub Temperature Coefficient; Cumulative Pollution Index of Wash Tub in Each Wash Among them, T i Indicates the temperature coefficient of the selected washing temperature for the i-th washing affecting the pollution degree of the washing tub.

[0088] In this embodiment, the washing temperature will affect the molecular activity and the degree of bacterial growth, so 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 coeffic...

Abstract

The invention discloses a control method of a washing machine. The washing machine calculates a pollution index in a washing drum in single washing by at least taking a selected program as an influence factor, and reminds a user to operate a self-cleaning program when accumulated pollution index of repeated washing reaches or excesses a critical value. Through the control method provided by the application, own operating parameters and data of the washing machine are converted into coefficients for the dirt level of the washing drum, so that the pollution level of the washing machine can be calculated and the user can be reminded; and the additional sensor and device are unnecessary, and the control method 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 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. ...
