[0043] Embodiment 1

[0044] When washing clothes, users often mix multiple clothes of different colors and materials into the washing machine and select the soak washing program. After soaking the clothes, they enter the main washing program. During the soaking process, the clothes of different materials and colors may stain each other, and the clothes after soaking are also more likely to be stained during the main washing stage, affecting the wearing effect and the user experience of using the washing machine.

[0045] As Figure 1 shown, to solve the above problems, this embodiment provides a control method for a washing machine. The washing machine is equipped with a detection device for detecting the material and color of clothes and the color of washing water, including the following steps:

[0046] S1: Detect the material and color of the clothes, and obtain the staining probability of the clothes according to the material and color information of the clothes;

[0047] S2: Determine whether the staining probability of the clothes is greater than the first staining probability P1. If so, do not perform washing and give a clothes staining reminder. If not, execute step S3;

[0048] S3: Determine whether the staining probability of the clothes is greater than the second staining probability P2. If so, directly enter the main washing program. If not, enter the soak washing program.

[0049] Among them, the first dyeing probability P1 is greater than the second dyeing probability P2. For example, the value of the first dyeing probability P1 is 50%. When the washing machine determines that the dyeing probability of the clothes exceeds 50%, it judges that the dyeing risk is too high, then it does not perform washing, and gives a clothing dyeing reminder to remind the user to take out the clothes. The value of the second dyeing probability P2 is 20%. When the washing machine determines that the dyeing probability of the clothes exceeds 20% and is lower than or equal to 50%, it judges that the dyeing risk is medium. At this time, if the user selects the soak washing program, the washing machine controls to skip the soaking stage and directly enter the main washing program to avoid the clothes being dyed during the soaking process. When the washing machine determines that the dyeing probability of the clothes is lower than or equal to 20%, it judges that the dyeing risk is low, and then the washing machine normally enters the soak washing program.

[0050] Optionally, in order to avoid inaccurate judgment of the dyeing probability of the clothes by the washing machine and further avoid mutual dyeing of the clothes, after entering the soak washing program, the following steps are also included:

[0051] Detect the color of the washing water during the soaking stage, and obtain the dyeing rate of the clothes according to the color of the washing water;

[0052] Judge whether the dyeing rate of the clothes is greater than the first dyeing rate F1. If so, end the soaking and enter the main washing stage. If not, continue to soak.

[0053] Among them, the first dyeing rate F1 is determined according to the color of the washing water. After the color depth of the washing water reaches a certain value, it is judged that the dyeing rate of the clothes reaches the first dyeing rate F1.

[0054] Optionally, the washing machine detects the color of the washing water every first set time t1 until it ends the soaking and enters the main washing stage.

[0055] The first set time t1 can be set according to actual needs. For example, it can be two minutes. The washing machine detects the color of the washing water every two minutes until it ends the soaking and enters the main washing stage.

[0056] Applying the above control method of the washing machine can reduce the occurrence of mutual dyeing of clothes during soaking and washing, and improve the user experience of using the washing machine.

[0057] Embodiment 2

[0058] When washing clothes, moderately heating the washing water can improve the activity of the detergent and stains, making the clothes cleaner. At the same time, each type of clothing material has its most suitable washing temperature range, and the optimal washing temperatures of different clothing materials are different; moreover, there are some clothing materials that are not suitable for high-temperature washing. When the temperature of the washing water exceeds its maximum tolerance temperature, it may deform, shrink, etc. in the high-temperature washing water, causing damage to the clothes.

[0059] As Figure 1 shown, to solve the above problems, this embodiment provides a control method for a washing machine. The washing machine is equipped with a detection device for detecting the material and color of clothes and the color of washing water. After entering the soaking washing program in step S3 above, the following steps are further included:

[0060] S4: Obtain the maximum tolerable temperature Tm of the clothes according to the material of the clothes;

[0061] S5: Obtain the proportion of different materials of the clothes, and obtain the soaking temperature range T1 - T2 according to the material of the clothes with the highest proportion;

[0062] S6: Judge whether Tm is less than T2. If so, execute step S7. If not, the soaking temperature range T1 - T2 remains unchanged;

[0063] S7: Judge whether Tm is less than T1. If so, adjust the soaking temperature range to below Tm. If not, adjust the soaking temperature range to T1 - Tm.

[0064] Among them, the soaking temperature range T1 - T2 is the most suitable soaking temperature range for the clothes. Soaking the clothes within this soaking temperature range T1 - T2 can obtain the best washing effect.

[0065] Generally, in one washing, there will be a mixture of clothes of multiple different materials. Therefore, in step S4, the washing machine obtains the maximum tolerable temperature of all the clothes' materials and takes the lowest value as the maximum tolerable temperature Tm.

[0066] In the same washing, there may be multiple materials with the highest proportion. Therefore, in step S5, when there are at least two materials with the highest proportion, take the intersection of the washing temperature ranges of all the materials with the highest proportion as the washing temperature range T1 - T2.

[0067] According to the above control method, the washing machine controls the temperature of the washing water, which can avoid damage to the clothes caused by high temperature and make the clothes cleaner to the greatest extent within the appropriate temperature range.

[0068] Embodiment Three

[0069] Due to the different degrees of dirtiness, materials, types, quantities, and weights of the clothes to be washed, as well as the dosage and types of detergents, the soaking time required for the best washing effect of the clothes also varies according to the above factors.

[0070] Therefore, in addition to the dyeing probability of the clothes, the reference factors for the soaking time of the clothes also include the degree of dirtiness, material, type, quantity, and weight of the clothes, as well as the dosage and types of detergents.

[0071] In the control method of the washing machine provided in this embodiment, after the above step S7, the following steps are further included:

[0072] S8: Determine the soaking time t according to at least one parameter among the dirtiness degree, material, type, quantity and weight of the clothes, and the dosage and type of the detergent, and the adjusted soaking temperature range.

[0073] The washing machine is provided with a detergent information input window, and the detergent information input window includes a two-dimensional code and / or a bar code scanning port. The washing machine obtains the type of the detergent by scanning the two-dimensional code and / or the bar code on the detergent package.

[0074] The detergent information input window further includes a man-machine interaction interface, and the user inputs and / or selects the type of the detergent through the man-machine interaction interface.

[0075] Using the detergent information input window to input the type of the detergent makes the input of the detergent type information simple and efficient, and improves the user experience.

[0076] Embodiment 4

[0077] As Figure 2 shown, in the control method of the washing machine provided in this embodiment, the washing machine is provided with a clothes detection device for obtaining parameter information of the clothes to be washed. Specifically, the clothes detection device includes at least one of a load sensor, a fabric sensor, a camera device and an image processor, and is used for detecting the color, type, quantity, weight, material and dirtiness degree information of the clothes to be washed.

[0078] The washing machine is further provided with a detergent information input window. When the washing machine performs washing, the corresponding washing program is determined according to the input detergent information and the parameter information of the clothes.

[0079] Each washing program is jointly determined by multiple parameters, and these parameters include the detergent dosage, the water inlet volume, the washing time, the washing temperature, the washing rotation speed and the rotation-stop ratio.

[0080] Generally speaking, the whole washing process of the washing machine includes a soaking stage, a main washing stage, a rinsing stage and a dehydration stage. At the same time, there are many brands and various styles of detergents for washing machines on the market at present. The dosages, the optimal washing concentrations and temperatures, whether pre-soaking is required and the soaking time are all different for different brands and styles of detergents during washing.

[0081] Therefore, specifically, the parameters of the washing program of the washing machine determined according to the detergent information include the detergent dosage, the water inflow during the soaking stage, the soaking time, the soaking temperature, the rotation speed and the rotation-stop ratio during the soaking stage, the water inflow during the main washing stage, the main washing time, the main washing temperature, the rotation speed and the rotation-stop ratio during the main washing stage, the water inflow during the rinsing stage, the rinsing time, the rinsing temperature, the rotation speed and the rotation-stop ratio during the rinsing stage (since the program selection during the dehydration stage is generally independent of the detergent used, it is not mentioned for the time being).

[0082] The detergent information entry window includes a QR code and / or a barcode scanning port. When washing, the user brings the QR code and / or barcode on the outer package of the used detergent close to the scanning port of the washing machine for scanning. The washing machine obtains the detergent information by scanning the QR code and / or barcode on the detergent package. At this time, the detergent information obtained by the washing machine by scanning is the information of the type of detergent (which brand and which model in this brand).

[0083] Most of the brands and models of detergents on the market are pre-stored in the washing machine. The pre-stored detergent information mainly includes the brand, model, dosage, use temperature, whether it is suitable for soaking washing and the soaking time of the detergent. The washing machine matches according to the brand and model information of the detergent obtained by scanning. After searching for the same brand and model information as the detergent obtained by scanning, it retrieves the information such as the dosage, use temperature, whether it is suitable for soaking washing and the soaking time of this kind of detergent, and determines the corresponding washing program according to this information.

[0084] Optionally, in order to better provide suitable washing services for users, the service provider establishes a detergent information database and establishes an information connection between the detergent information database and the user's washing machine. When the washing machine cannot match the same brand and model information of the detergent obtained by scanning in the pre-stored detergent information, it connects to the detergent information database and matches the information such as the dosage, use temperature, whether it is suitable for soaking washing and the soaking time of the detergent stored in the detergent information database according to the brand and model information of the detergent.

[0085] Optionally, the washing machine does not pre-store detergent information and does not set a module for storing detergent information. Instead, after obtaining the detergent information by scanning the code, it directly connects to the detergent information database and matches the information such as the dosage, use temperature, whether it is suitable for soaking washing and the soaking time of the detergent stored in the detergent information database according to the brand and model information of the detergent.

[0086] Optionally, the washing machine is provided with a module for storing detergent information, but does not pre-store the detergent information. An information connection is established between the detergent information database and the user's washing machine. The washing machine downloads the detergent information from the database, stores it, and matches the dosage, usage temperature, whether it is suitable for soaking washing, and soaking time information of the stored detergent according to the brand and model information of the detergent obtained by scanning the code.

[0087] Optionally, the service provider updates the detergent information in the detergent information database in real time. When the washing machine starts to work each time, it establishes an information connection with the detergent information database to update the stored detergent information in real time.

[0088] The washing machine performs corresponding washing according to the determined washing program, and controls the detergent dosage, water inlet volume in the soaking stage, soaking time, soaking temperature, rotation speed and rotation-stop ratio in the soaking stage, water inlet volume in the main washing stage, main washing time, main washing temperature, rotation speed and rotation-stop ratio in the main washing stage, water inlet volume in the rinsing stage, rinsing time, rinsing temperature, rotation speed and rotation-stop ratio in the rinsing stage.

[0089] Embodiment Five

[0090] This embodiment provides a control method for a washing machine. In this embodiment, the washing machine is provided with a detergent information entry window, and the detergent information entry window includes a human-machine interaction interface. The user inputs and / or selects detergent information through the human-machine interaction interface.

[0091] Preferably, the human-machine interaction interface of the washing machine is an operation display panel. When the user is washing, the user views the product information on the outer package of the detergent and enters the product information on the outer package into the washing machine through the operation display panel.

[0092] Specifically, the entry method of the product information can be as follows:

[0093] 1. Typing input. After opening the operation display panel, the search option will be displayed on the panel home page. The user clicks the search option, selects the input method, types in the keywords of the brand and model of the detergent, and then clicks search. At this time, the built-in processing program of the washing machine will search the detergent information stored in the washing machine and / or the detergent information database according to the keywords input by the user, and display it in the order from high to low according to the degree of proximity. The display method is a combination of pictures and texts. The user compares the display results with the outer package of the detergent, accurately selects the information of the used detergent, and clicks confirm to proceed to the next washing program.

[0094] 2. Click to select. After opening the operation display panel, the selection option will be shown on the panel home page. The user clicks on the selection option to enter the selection interface, where the brands of various common detergents on the market are displayed. The user clicks on the corresponding brand, enters the brand page to select a specific product of this brand, and then clicks to confirm to proceed to the next washing program.
