[0021] The preferred embodiments of the application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the application, and are not intended to limit the protection scope of the application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios. Such changes related to application scenarios do not deviate from the basic principles of the application and belong to the protection scope of the application.

[0022] Unless otherwise specified, the term "a plurality of" means two or more.

[0023] The term "corresponding" can refer to an association or binding relationship. A and B correspond to each other means that there is an association or binding relationship between A and B.

[0024] In a first aspect, the application provides a dish washing method. The dish washing method is used in a dishwasher to wash dishes.

[0025] Figure 1 is a main step flow chart of the dish washing method provided by the application.

[0026] In combination with Figure 1 , the dish washing method provided by the application includes the following steps:

[0027] S101, determine the target detergent dosage according to the weight of the tableware.

[0028] Generally speaking, heavier tableware tends to have a larger surface area and is more likely to accumulate stains and grease; or heavier tableware can contain more grease or other residues, which requires more detergent to break down and remove the stains. Therefore, there is a certain positive relationship between the weight of the tableware and the target dosage of the detergent, and the target dosage of the detergent can be determined according to the positive relationship and the weight of the tableware.

[0029] S102, in the case where the target dosage is greater than or equal to the dosage threshold, enter the pre-washing stage.

[0030] S103, in the case where the target dosage is less than the dosage threshold, directly enter the main washing stage. In this step, the target dosage of the detergent is small, so there is no need to pre-wash first and directly enter the main washing stage.

[0031] In the case of using the above technical solution, the tableware washing method provided by the present application determines the target dosage of the detergent according to the weight of the tableware washed by the user, and adopts different washing methods according to the target dosage. In the case where the target dosage is small, directly enter the main washing stage. In the case where the target dosage is large, first enter the pre-washing stage to pre-wash the tableware. In this way, the cleaning effect of the tableware can be guaranteed, and in the case where the amount of tableware is small, there is no need to enter the pre-washing stage, which is beneficial to saving detergent and washing time, and brings better user experience.

[0032] Figure 2 is the step flow chart of the pre-washing stage in the present application, in some embodiments, in combination with Figure 2 As shown, the pre-washing stage includes the following steps:

[0033] S201, determine the pre-washing dosage of the detergent in the pre-washing stage according to the target dosage. For example, the target dosage is a grams, and the pre-washing dosage is 1 / 2a grams.

[0034] S202, obtain the pre-washing duration of the pre-washing stage.

[0035] S203, in the pre-washing stage, the pre-washing dosage of the detergent is added, and the pre-washing duration is washed.

[0036] When pre-washing is needed, it indicates that the amount of tableware is large, and the target dosage is relatively large. However, the dirtiness of the tableware cannot be directly obtained, so a part of the detergent is added in the pre-washing stage to quickly wash the tableware, which is convenient for judging the dirtiness of the tableware according to the pre-washing condition, so as to further judge the dosage of the detergent and the washing time in the main washing stage. By setting the pre-washing stage, the cleanliness of the tableware can be ensured, and the dosage of the detergent can be adjusted according to the amount and dirtiness of the tableware, which is beneficial to saving the detergent and washing time.

[0037] Optionally, the pre-washing dosage is less than the target dosage, and the pre-washing dosage accounts for 30% to 60% of the target dosage. For example, the pre-washing dosage accounts for 30%, 40%, 50% or 60% of the target dosage. Illustratively, the target dosage is a grams, and the pre-washing dosage is 1 / 2a grams.

[0038] When pre-washing is needed, it indicates that the amount of tableware is large, and the target dosage of the detergent is relatively large. A small amount of detergent is added in the pre-washing stage to quickly wash the tableware, which is convenient for judging the dirtiness of the tableware according to the pre-washing condition, so as to further judge the dosage of the detergent and the washing time in the main washing stage, which is beneficial to saving the detergent and washing time.

[0039] In some embodiments, after entering the pre-washing stage, the washing strategy in the main washing stage is determined according to the pre-washing condition in the pre-washing stage. When pre-washing is needed, it indicates that the amount of tableware is large, and the target dosage of the detergent is large. At this time, there may be a situation that the tableware is relatively clean or the tableware is relatively dirty, so a part of the detergent is added for pre-washing, and the washing strategy such as the dosage of the detergent, the washing time and whether to change water in the subsequent main washing stage is determined according to the pre-washing condition. The washing strategy can ensure the washing effect and save the detergent and energy.

[0040] Figure 3 is Figure 1 A detailed step flow chart of one step in the method is shown in some embodiments, which combines the steps of Figure 3 As shown in FIG. 6, the step of “determining the washing strategy in the main washing stage according to the pre-washing condition in the pre-washing stage” further includes:

[0041] S301, detecting a first turbidity value of residual water after pre-washing is completed.

[0042] That is, after the pre-washing stage is completed, the turbidity value of the residual water is detected, and the turbidity value is recorded as the first turbidity value.

[0043] S302, obtaining a total washing time.

[0044] The total washing time can be determined according to the type of the dishwasher, the washing mode and the number of tableware, and is not specifically limited herein. In the present application, when the tableware washing method comprises a pre-washing stage and a main washing stage, the total washing time is the sum of the time lengths of the pre-washing stage and the main washing stage; when the tableware washing method only comprises a main washing stage, the total washing time is the time length of the main washing stage.

[0045] S303, determining the main washing time length of the main washing stage according to the total time length and the pre-washing time length.

[0046] Optionally, the main washing time length is obtained by subtracting the pre-washing time length from the total time length.

[0047] S304, in the case where the first turbidity value is greater than or equal to the turbidity value threshold, replacing the washing water and then adding the target adding amount of detergent, and continuing to wash for the total time length.

[0048] The replacement of the washing water comprises discharging the residual water after washing and injecting clean water. In the case where the first turbidity value is greater than or equal to the turbidity value threshold, the tableware is relatively dirty, and it is considered that the pre-washing stage is invalid washing, so the total washing time is continued to ensure the washing effect.

[0049] S305, in the case where the first turbidity value is less than the turbidity value threshold, continuing to wash for the main washing time length. In step S305, the washing water is not replaced, and the detergent is not continuously added. In the case where the first turbidity value is less than the turbidity value threshold, the tableware is relatively clean, and it is considered that the pre-washing stage is valid washing, so the main washing time length is continued, which is beneficial to shorten the washing time and reduce the power consumption.

[0050] The present embodiment needs to be pre-washed to explain that the number of tableware is relatively large, and further, the first turbidity value is the turbidity value of the residual water after the pre-washing is completed. When the first turbidity value is greater than or equal to the turbidity threshold, it proves that the tableware is relatively dirty, and in this case, the number of tableware is large and the dirtiness is serious, so it is necessary to replace the washing water in the main washing stage, add a relatively large amount of detergent, and wash for a relatively long time to ensure that the tableware is clean. When the first turbidity value is less than the turbidity threshold, it proves that the tableware is relatively clean although the number of tableware is large, so it is not necessary to replace the washing water and continuously add the detergent in the main washing stage, and the washing time is relatively short, which can not only ensure that the tableware is clean, but also save the washing cost such as the detergent, the washing time and the water.

[0051] Figure 4 is the case where the target adding amount is less than the adding amount threshold, the detailed step flow chart of the main washing stage. As shown in Figure 4 , the main washing stage comprises the following steps in the case where the target adding amount is less than the adding amount threshold:

[0052] S401, injecting clean water and detecting the contrast turbidity value of the clean water.

[0053] That is, the turbidity value of the clean water is detected, and the turbidity value of the clean water is recorded as a contrast turbidity value.

[0054] S402, the target amount of detergent is put in, and the first duration is washed.

[0055] When there is no need for pre-washing and directly entering the main washing stage, it means that the number of tableware is relatively small, and the tableware is washed quickly by adding the detergent once.

[0056] S403, the second turbidity value of the remaining water after washing the first duration is detected.

[0057] That is, the turbidity value of the remaining water after washing the first duration is detected, and the turbidity value is recorded as a second turbidity value.

[0058] S404, according to the contrast turbidity value and the second turbidity value, it is determined whether the main washing stage is ended.

[0059] When there is no need for pre-washing and directly entering the main washing stage, it means that the number of tableware is relatively small, and the target amount of detergent is relatively small, and the tableware is washed quickly by adding the detergent once. Although the number of tableware is relatively small, there may be a situation that the tableware is heavily soiled, so the tableware is washed for a first duration, and the first duration is short. By detecting the second turbidity value of the remaining water after washing the first duration, the soiling condition of the tableware can be quickly judged according to the second turbidity value and the contrast turbidity value, and then it is determined whether the main washing stage is ended. In this way, it is beneficial to ensure the cleaning effect of the tableware.

[0060] In some embodiments, the step of "determining whether the main washing stage is ended according to the contrast turbidity value and the second turbidity value" further comprises: in the case of m1-m0≥Δm, according to the total washing duration t 总 and the first duration t1, a second duration t2 is obtained, and the main washing stage is ended after continuing to wash for the second duration t2. In the case of m1-m0<Δm, the first confirmation washing is performed, and according to the first confirmation washing, it is determined whether the main washing stage is ended. Wherein, m1 is the second turbidity value, m0 is the contrast turbidity value, and Δm is a difference threshold value.

[0061] m1-m0≥Δm indicates that the turbidity of the washing water changes obviously after the first washing time, and the stains on the tableware can be dissolved into the washing water, so the first time is effective washing, and the main washing stage can be ended after continuing to wash for the second time. m1-m0<Δm indicates that the turbidity of the washing water does not change obviously after the first washing time, and there are two possible situations, the first possible situation is that the tableware is relatively clean, and the second possible situation is that the tableware has stubborn stains, and the stubborn stains on the tableware cannot be dissolved into the washing water through simple cleaning for the first time, so the first confirmation washing is needed to ensure that the tableware is clean, and whether the main washing stage is ended is determined according to the first confirmation washing. In this way, the cleaning effect of the tableware can be ensured.

[0062] Optionally, the total washing time t 总 and the first time t1, the second time t2 is obtained. 总

[0063] Optionally, t1 总 It can be understood that the first time t1 is relatively short, about 3min-8min, and through the first washing time of the tableware, the turbidity value of the washing water after the first washing time is detected, the dirt condition of the tableware can be determined quickly.

[0064] In some embodiments, the step of "carrying out the first confirmation washing" further includes heating the washing water. The third time t3 is continued to wash. Wherein, the third time t3 is greater than the first time t1 and less than the total time t 总 In the process of the first confirmation washing, heating the washing water and prolonging the washing time (t3>t1) are both beneficial to improve the cleaning effect.

[0065] In some embodiments, the step of "determining whether the main washing stage is ended according to the first confirmation washing" further includes detecting a third turbidity value of the remaining water after the first confirmation washing. In the case of m2-m0≥Δm, the seventh time t7 is obtained according to the total washing time and the first confirmation washing time, and the main washing stage is ended after continuing to wash for the seventh time. In the case of m2-m0<Δm, the second confirmation washing is carried out, and whether the main washing stage is ended is determined according to the second confirmation washing. Wherein, m2 is the third turbidity value. The first confirmation washing time is the third time t3 mentioned above, and t7=t 总 -t3.

[0066] ​The first confirmation washing improves the cleaning strength of the tableware by heating and prolonging the washing time. After the first confirmation washing, if m2-m0≥Δm, it indicates that the turbidity of the washing water changes obviously after the cleaning strength is improved, the tableware has stubborn stains and the stains on the tableware can be dissolved into the washing water. At this time, the first time washing is considered as invalid washing, the first confirmation washing is effective washing, and the main washing stage is ended after the tableware is washed for the seventh time with heating.

[0067] In some embodiments, the step of "carrying out the second confirmation washing" further comprises heating the washing water. The washing is continued for a sixth time t6. Wherein, t 总 >t6>t3>t1. In the process of the second confirmation washing, the washing water is heated and the washing time is further prolonged (t6>t3>t1), which is beneficial to further improve the cleaning effect.

[0068] In some embodiments, the step of "determining whether the main washing stage is ended according to the situation of the second confirmation washing" further comprises detecting a fourth turbidity value of the residual water after the second confirmation washing. In the case of m3-m0≥Δm, a fourth time t4 is obtained according to the total time and the sixth time, and the main washing stage is ended after the washing is continued for the fourth time. In the case of m3-m0<Δm, the heating is stopped, a fifth time is obtained according to the total time, the first time, the third time and the time of the second confirmation washing, and the main washing stage is ended after the washing is continued for the fifth time. Wherein, m3 is the fourth turbidity value. Optionally, t4=t 总 -t6. Optionally, the time of the second confirmation washing is the sixth time t6 mentioned above, and t5=t 总 -t1-t3-t6.

[0069] The second confirmation washing further improves the cleaning strength of the tableware by further heating and further prolonging the washing time. After the second confirmation washing, if m3-m0≥Δm, it indicates that after the cleaning strength is further improved, the turbidity of the washing water changes obviously, the tableware has stubborn stains, and the stains on the tableware can be dissolved into the washing water, and the main washing stage can be ended after the fourth washing time t4 is maintained. m3-m0<Δm indicates that after the cleaning strength is improved, the turbidity of the washing water does not change obviously, and the tableware is considered to be relatively clean after two confirmation washings, and the main washing stage can be ended after the fifth washing time is stopped.

[0070] In the case of m3-m0≥Δm, the washing in the first time t1 and the third time t3 stages is regarded as invalid washing, the washing in the sixth time t6 stage is regarded as effective washing, and the main washing stage is ended after the fourth washing time t4 is continued. 总 -t6.

[0071] In the case of m3-m0<Δm, the fifth time is obtained according to the total time, the first time, the third time, and the length of the second confirmation washing, and the main washing stage is ended after the fifth washing time is continued. At this time, the tableware is considered to be relatively clean, the first time, the third time, and the second confirmation washing are all effective washing, and the main washing stage is ended after the relatively short fifth washing time is continued.

[0072] Optionally, the tableware washing method provided by the present application further comprises rinsing the tableware after the main washing stage is ended. In this way, the cleaning effect of the tableware can be further improved.

[0073] Further, the present application also provides a dishwasher comprising a controller configured to execute the above-mentioned tableware washing method.

In the case of a small target amount of detergent, the main washing stage is directly entered. In the case of a large target amount of detergent, the pre-washing stage is entered first to pre-wash the tableware, and the pre-washing condition in the pre-washing stage determines the washing strategy in the main washing stage. In this way, the cleaning effect of the tableware can be guaranteed, and in the case of a small amount of tableware, the pre-washing stage is not needed, which is beneficial to saving detergent and washing time, and brings better user experience.
