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 the present embodiment, such as Figure 1 As shown, there is provided a washing machine control method, the washing machine to the time interval of each adjacent wash and the washing program selected for each wash as the influencing factor to measure the pollution index of the washing barrel in a single wash, when the cumulative pollution index of multiple washes reaches or exceeds the critical value, reminds the user to run a self-cleaning program.

[0055] In the present embodiment, when the washing machine is used, different procedures in the washing cycle cause the degree of dirty washing barrels to be different, for example, the drying process will reduce the probability of survival of microorganisms in the washing cylinder, so that the degree of pollution decreases, relatively, the dirt and bacteria in the clothing enter the washing water containing nitrogen, phosphine elements, which improves the degree of pollution of the washing barrel; Further, after the end...

Embodiment 2

[0076] The difference between the present embodiment and Example 1 is:

[0077] In the present embodiment, the cumulative interval coefficient where k i The interval coefficient indicating the interval coefficient of each washing interval before the ith wash affecting the degree of contamination of the wash barrel at the time of the ith wash, and the interval coefficient k for the first wash at i=1 in the statistical period 1 =1,i> 1 interval coefficient k for the first wash 1 ＝0。

[0078] In the present embodiment, the washing machine records the time interval during each washing week respectively within the statistical cycle, when determining the cumulative interval coefficient of a washing cycle, while accumulating the interval coefficient of each washing cycle before the washing, in order to better illustrate the present invention, for example, the following:

[0079] During the first wash, since there is no interval between the washes, but the procedure coefficient P is not 0...

Embodiment 3

[0086] The difference between the present embodiment and Example 1 or 2 is:

[0087] In the present embodiment, the washing temperature of the washing machine is adjustable, the pollution index of the washing barrel in a single wash s = P×K×T, wherein T expresses the temperature coefficient of the washing temperature selected in the single wash affecting the degree of pollution of the wash barrel; where, T i Represents the temperature coefficient of the selected washing temperature of the ith wash affecting the degree of contamination of the washing barrel.

[0088]In the present embodiment, the temperature of washing will affect the molecular activity and the degree of growth of bacteria, 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, different coefficients are set according to different washing temperatures, characterizing their influen...

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 selected washing program as the influencing factor, and reminds the user to run the washing machine when the accumulated pollution index of multiple washings reaches or exceeds a critical value. Self-cleaning program. The control method provided in this application converts the operating parameters and data of the washing machine into coefficients that affect the degree of dirtiness of the washing tub, so that the degree of pollution of the washing machine can be calculated and the user can be prompted without additional sensors and devices, and is suitable for popularization and use.

Description

Technical field [0001] The present invention belongs to the field of clothing processing technology, specifically, relates to a washing machine control method. Background [0002] According to research statistics, the dirt of the washing machine washing bucket mainly comes from microorganisms between the gaps in the clothing fibers and on the surface of the clothing (such as Pseudomonas aeruginosa, E. coli, mold, etc.), as well as the odor produced by the humid environment in the washing machine washing barrel when the air is not circulating. These problems bring secondary pollution during subsequent washing of clothes, causing harm to the health of users. [0003] Most of the existing washing machines themselves have the function of washing bucket self-cleaning, 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, the frequency of users using washing bucke...
