[0057] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] The intelligent washing control method for a dishwasher provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the control end 102 communicates with the dishwasher 104 through the network. Among them, the control end can be a control end independent of the dishwasher; it can also be a controller deployed in the dishwasher. The control end 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The dishwasher 104 is a household appliance for automatically washing and drying kitchen supplies such as tableware, pots, knives, and glassware. It removes food residues and grease by using hot water, detergents, and mechanical force, and then dries the washed tableware by heating elements or fans. Specifically, the control end 102 obtains the expected cleanliness corresponding to each washing stage of the dishwasher 104 during the process of controlling the intelligent washing of the dishwasher; when receiving an instruction for completing the placement of tableware for the dishwasher 104, the amount of detergent to be added in the first washing stage is determined based on the number of placed tableware; for each washing stage except the first washing stage, after adding detergent according to the amount added in the previous washing stage and washing is performed, the actual cleanliness of the sewage in the dishwasher 104 is determined; when the actual cleanliness of the sewage in the dishwasher 104 does not meet the cleaning conditions, the amount added in the previous washing stage is updated according to the numerical difference between the actual cleanliness and the expected cleanliness of the previous washing stage, and the amount of detergent to be added in the current washing stage is determined; when the actual cleanliness of the sewage in the dishwasher 104 meets the cleaning conditions, the washing is terminated.

[0059] In one embodiment, Figure 2 As shown, a dishwasher intelligent washing control method is provided, and the method is applied to Figure 1 The control end in the example is used to illustrate, including the following steps:

[0060] Step S202, obtaining the expected cleanliness corresponding to each washing stage of the dishwasher.

[0061] Among them, a dishwasher is a household appliance that automatically washes and dries kitchen items such as tableware, pots, knives, glassware, etc. It uses hot water, detergent and mechanical force to remove food residues and grease, and then dries the washed tableware through heating elements or fans.

[0062] The washing phase refers to the phase in which the dishwasher washes the placed tableware. The dishwasher generally pre-washes the tableware first, using a lower water temperature (usually not exceeding 40°C) to preliminarily rinse the tableware to remove large particles of food residue and loose dirt, which helps to loosen and remove food residue adhering to the tableware and prepare for the next main wash phase. After that, it enters the main wash phase, and the dishwasher uses hotter water (usually between 60°C and 75°C) to wash the tableware to ensure more thorough cleaning and disinfection. And in the main wash phase, the dishwasher will rinse the tableware in multiple cycles to ensure that the detergent and dirt are thoroughly washed away. After the washing process is completed, the dishwasher will use a dryer to dry the tableware to help speed up the drying of the tableware. The pre-wash and main wash phases of the dishwasher are designed to maximize the cleaning effect and efficiency while reducing the consumption of energy and water resources. In this application, the washing phase of the dishwasher includes a pre-wash phase and a main wash phase.

[0063] The expected cleanliness refers to the expected degree of cleaning process for the dishes. For example, the expected cleanliness may mean that after the dishes are cleaned, the oil content in the washing water in which the dishes are placed is 0.1%.

[0064] Specifically, the expected cleanliness corresponding to each washing stage in the dishwasher is obtained, and the expected degree of dishwashing cleaning in each washing stage can be determined. For example, the expected cleanliness corresponding to each washing stage can be the same or different, and is set according to the cleaning requirements, which is not limited here.

[0065] Step S204, when receiving an instruction for the dishwasher to complete placing dishes, the amount of detergent to be added in the first washing stage is determined based on the amount of placed dishes.

[0066] The tableware placement completion instruction refers to the cleaning instruction sent by the dishwasher after the tableware to be cleaned in this cleaning process is placed. In some embodiments, for example, a pressure sensor can be provided in the dishwasher to detect the change in the weight of the tableware during the tableware placement process. If it is detected that the pressure continues to rise to a certain value during the tableware placement process and the pressure remains unchanged, it can be determined that the tableware is placed.

[0067] The number of dishes refers to the number of dishes placed in the dishwasher to be cleaned. Detergents refer to cleaning products specially designed for cleaning dishes in a dishwasher. They usually contain strong cleaning ingredients that can effectively remove grease, food residues and stains under the high temperature and high pressure water flow of the dishwasher. Types of dishwasher detergents include dishwashing powder, dishwashing tablets, dishwashing liquid and dishwashing gel beads. In this application, detergents specifically refer to rinse aid and dishwashing powder.

[0068] Specifically, after receiving the instruction that the tableware has been placed in the dishwasher, the control end can determine the amount of detergent to be put in the first washing stage according to the number of tableware placed by the user, so that the detergent can be put in according to the amount of put in later. In some embodiments, the control end can obtain the association condition between the preset number of tableware and the amount of detergent put in, map the number of tableware to the association condition, and determine the amount of detergent put in corresponding to the number of tableware in the first washing stage. In some embodiments, the control end can determine the number of tableware placed according to the number of compartments occupied by the tableware in the dishwasher.

[0069] Step S206, for each washing stage except the first washing stage, after adding detergent according to the amount added in the previous washing stage and washing, determine the actual cleanliness of the sewage in the dishwasher.

[0070] The actual cleanliness refers to the actual cleanliness of the sewage in the dishwasher after the previous washing stage is completed, which can be used to characterize the washing degree of the previous washing stage.

[0071] Specifically, for a dishwasher, the first washing stage is generally a pre-wash stage, and the remaining washing stages except the first washing stage are all main washing stages. Generally, the pre-wash stage is only performed once. If the main washing stage is not cleaned in place, there will be multiple situations. In order to reduce the waste of water and detergents under the premise of ensuring cleanliness, it is necessary to determine the actual cleanliness of the sewage after washing in each remaining washing stage after washing in each remaining washing stage. It can be understood that for the second washing stage, the previous washing stage of the second washing stage is the first washing stage, that is, the pre-wash stage. Exemplarily, the number of the remaining washing stages can be one or more. After the detergent is added and washed according to the amount of the first washing stage, the actual cleanliness of the sewage in the dishwasher meets the requirements, and the washing can be ended. At this time, there is only one remaining washing stage, which is the second washing stage. After the detergent is added and washed according to the amount of the first washing stage, the actual cleanliness of the sewage in the dishwasher does not meet the requirements, and it is necessary to wash again. At this time, there are multiple remaining washing stages.

[0072] Step S208, when the actual cleanliness of the sewage in the dishwasher does not meet the cleaning conditions, the amount of detergent added in the previous washing stage is updated according to the numerical difference between the actual cleanliness and the expected cleanliness in the previous washing stage, and the amount of detergent added in the current washing stage is determined.

[0073] The cleaning condition refers to the standard condition of cleanliness, for example, the cleaning condition may be that the cleanliness reaches 0.01%. The current washing stage refers to the stage in which washing is currently being prepared but has not yet been carried out. It can be understood that the washing stage before the current washing stage has been washed, that is, the current washing stage is one of the remaining washing stages except the first washing stage.

[0074] Specifically, after washing is completed in the previous washing stage, it is necessary to judge the cleaning conditions of the actual cleanliness of the sewage in the dishwasher in the previous washing stage to determine the washing situation of the previous washing stage. If the actual cleanliness of the sewage in the dishwasher does not meet the cleaning conditions, it is considered that washing is still required. Then, it is necessary to update the amount of detergent added in the previous washing stage based on the numerical difference between the actual cleanliness and the expected cleanliness of the previous washing stage to determine the amount of detergent added in the current washing stage.

[0075] In some embodiments, since the numerical difference between the actual cleanliness and the expected cleanliness of the previous washing stage may be larger or smaller, updating the delivery quantity according to a fixed delivery adjustment step may result in waste of materials or poor final cleaning efficiency, and there is a problem of poor flexibility. Therefore, the delivery adjustment step can be set to a variable step, and the delivery adjustment step is adjusted based on the numerical difference between the actual cleanliness and the expected cleanliness of the previous washing stage.

[0076] In some embodiments, a dosage update model may also be trained, and the numerical difference between the actual cleanliness and the expected cleanliness of the previous washing stage is input into the dosage update model, and the output is the dosage of detergent in the current washing stage.

[0077] Step S210, when the actual cleanliness of the sewage in the dishwasher meets the cleaning condition, the washing is ended.

[0078] Specifically, when the actual cleanliness of the sewage in the dishwasher meets the cleaning conditions, it means that the dishes in the dishwasher have reached the cleaning standard and washing can be stopped. After washing, you can choose to dry the wet dishes in a dryer, or you can choose to let the dishes dry naturally according to the residual temperature in the dishwasher.

[0079] The above-mentioned intelligent washing control method for a dishwasher obtains the expected cleanliness corresponding to each washing stage of the dishwasher. When receiving an instruction that tableware placement is completed for the dishwasher, the amount of detergent to be added in the first washing stage is determined based on the number of placed tableware. The amount of detergent added can be flexibly adjusted according to the number of placed tableware, so as to carry out targeted washing and improve washing efficiency. Afterwards, for each washing stage except the first washing stage, after adding detergent according to the amount added in the previous washing stage and washing, the actual cleanliness of the sewage in the dishwasher is determined. The actual washing situation in the previous washing stage can be determined. If the actual cleanliness of the sewage in the dishwasher does not meet the requirements, the actual cleanliness of the sewage in the dishwasher is determined. Under the cleaning conditions, the amount of detergent added in the previous washing stage is updated according to the numerical difference between the actual cleanliness and the expected cleanliness of the previous washing stage, and the amount of detergent added in the current washing stage is determined. The amount of detergent added can be adjusted again based on the gap between the actual washing situation and the expected washing situation to avoid the situation where too much detergent is added when the actual washing situation is already very clean, or the actual washing situation is still relatively dirty but the amount of detergent added is insufficient. When the actual cleanliness of the sewage in the dishwasher meets the cleaning conditions, the washing is ended, and a complete dishwashing process can be completed, thereby improving the flexibility of the dishwasher's intelligent washing.

[0080] In one embodiment, Figure 3 As shown, the dishwasher intelligent washing control method also includes:

[0081] Step S302, obtaining the washing water temperature of the dishwasher, injecting clean water into the dishwasher, and heating the clean water.

[0082] The volume of clean water injected is a set value, which can be set according to the volume of the dishwasher. The washing water temperature refers to the water temperature of the dishwasher for washing dishes, which is generally a preset value. For example, the washing water temperature of the dishwasher can be set to 50°C, 60°C or 70°C.

[0083] Specifically, hot water has a higher temperature and greater molecular thermal motion than cold water. Under the action of hot water, grease is more easily dissolved and decomposed, and thus easier to wash away. Therefore, using hot water to wash dishes can more effectively remove grease and make dishes cleaner. Therefore, after injecting clean water, the clean water can be heated to reach the preset washing water temperature obtained previously, so as to facilitate subsequent dishwashing.

[0084] Step S304, determining the number of placed dishes based on the heating time of the clean water from the initial water temperature to the washing water temperature.

[0085] The heating time refers to the time required for the clean water to be heated from the initial water temperature to the washing water temperature. For example, if the initial water temperature of the clean water is 30°C and the washing water temperature is 60°C, and it takes 5 minutes to heat the clean water from 30°C to 60°C, then these 5 minutes are the heating time of the clean water.

[0086] Specifically, since tableware absorbs heat, when soaked in the same volume of clean water, the more tableware there is, the more heat the tableware absorbs, and the heating time of the clean water will be longer. Therefore, the number of tableware placed can be determined based on the heating time of the clean water from the initial water temperature to the cleaning water temperature, thereby improving the convenience and accuracy of determining the number of tableware.

[0087] In one embodiment, the amount of detergent to be added in the first washing stage (i.e., step S204) is determined based on the amount of placed dishes. Figure 4 As shown, the following steps are included:

[0088] Step S402, obtaining the association condition between the preset number of dishes and the amount of detergent to be put in.

[0089] Specifically, association conditions between different numbers of tableware and the amount of detergent added can be pre-set. For example, when the number of tableware is 10 plates, the amount of detergent added is 10g, and when the number of tableware is 20 plates, the amount of detergent added is 20g.

[0090] Step S404, mapping the number of dishes to the associated conditions, and determining the amount of detergent to be added corresponding to the number of dishes in the first washing stage.

[0091] In the above steps, the association condition between the number of dishes and the amount of detergent to be added has been pre-established. Therefore, you only need to map the known number of dishes in this washing process to the association condition to determine the amount of detergent to be added corresponding to the number of dishes in the first washing stage. For example, the preset association condition is that when the number of dishes is 10 plates, the amount of detergent to be added is 10g, and when the number of dishes is 20 plates, the amount of detergent to be added is 20g. It is known that the number of dishes in this washing process is 10 plates, so it can be determined that the amount of detergent to be added corresponding to the number of dishes in the first washing stage is 10g. The amount of detergent to be added can be accurately determined based on the number of dishes, thereby improving the washing effect.

[0092] In one embodiment, after the detergent is added according to the amount added in the previous washing stage and washing is performed, the actual cleanliness of the sewage in the dishwasher is determined (i.e., step S206), which can be as follows: Figure 5 As shown, the following steps are included:

[0093] Step S502, after adding detergent according to the amount added in the previous washing stage and washing, a detection instruction is sent to the cleanliness sensor installed on the dishwasher.

[0094] Among them, the cleanliness sensor is a device used to measure the concentration of suspended particles in liquids. It has a wide range of applications in environmental monitoring, water quality testing, and industrial production. The working principle of the cleanliness sensor is based on the principle of optical scattering. When light passes through a liquid, suspended particles scatter the light, causing the intensity of the light to change. The sensor determines the cleanliness of the liquid by measuring the scattered intensity of the light.

[0095] The detection instruction is an instruction sent by the control end to the cleanliness sensor to perform cleanliness detection on the sewage in the dishwasher.

[0096] Specifically, the dishwasher dispenses detergent according to the amount dispensed in the previous washing stage and performs washing. It is necessary to determine the washing effectiveness of the previous washing stage. Therefore, the control end needs to send a detection instruction to the cleanliness sensor installed on the dishwasher to enable the cleanliness sensor to start detection.

[0097] Step S504: obtaining the actual cleanliness of the sewage in the dishwasher detected by the cleanliness sensor based on the detection instruction.

[0098] Specifically, after the cleanliness sensor completes the detection, the control end needs to obtain the actual cleanliness of the sewage in the dishwasher detected by the cleanliness sensor based on the detection instruction, so as to determine the actual cleanliness of the sewage in the dishwasher for subsequent washing or drying operations.

[0099] In one embodiment, the amount of detergent added in the previous washing stage is updated to determine the amount of detergent added in the current washing stage (ie, step S208), which can be as follows: Figure 6 As shown, the following steps are included:

[0100] Step S602: When the numerical difference indicates that the actual cleanliness is greater than the expected cleanliness, the amount of detergent added is increased according to a preset step length to determine the amount of detergent added in the current washing stage.

[0101] The preset step size refers to a step size value predefined in certain automation or calculation processes, which is used to determine the interval or size of each step in iteration, calculation or data processing.

[0102] Specifically, if the actual cleanliness is greater than the expected cleanliness of the previous washing stage, the washing process of the previous washing stage failed to meet the expectations of the previous washing stage, that is, the washing process of the previous washing stage was not ideal. Therefore, it is necessary to increase the amount of detergent added according to the preset step size, determine the amount of detergent added in the current washing stage, and increase the washing intensity of the current washing stage.

[0103] Step S604: when the numerical difference indicates that the actual cleanliness is less than or equal to the expected cleanliness, the amount of detergent added is reduced according to a preset step size to determine the amount of detergent added in the current washing stage.

[0104] Specifically, if the actual cleanliness is less than or equal to the expected cleanliness of the previous washing stage, the washing process of the previous washing stage has reached or exceeded the expectations of the previous washing stage, that is, the washing process of the previous washing stage is extremely ideal. Therefore, the amount of detergent added can be reduced according to the preset step length, the amount of detergent added in the current washing stage can be determined, the washing intensity of the current washing stage can be reduced, and the waste of detergent can be reduced. Exemplarily, the amount of fresh water in the current washing stage can also be adjusted based on the numerical difference. The specific process is similar to the above-mentioned process of updating the amount of detergent added, and will not be repeated here.

[0105] In the above embodiment, the amount of detergent added in the current washing stage is updated by the difference between the actual cleanliness and the expected cleanliness of the previous washing stage, and the washing materials can be adaptively adjusted according to the actual washing situation, thereby improving the flexibility of the washing process and reducing resource waste.

[0106] In one embodiment, Figure 7 As shown, the dishwasher intelligent washing control method also includes the following steps:

[0107] Step S702: Add detergent according to the amount of detergent added in the current washing stage and wash the dishes to determine the actual cleanliness of the sewage in the dishwasher in the current washing stage.

[0108] Specifically, after determining the amount of detergent to be added in the current washing stage, the above washing process needs to be repeated, detergent is added according to the amount of detergent to be added in the current washing stage and the dishes are washed to determine the actual cleanliness of the sewage in the dishwasher in the current washing stage. It can be understood that the method of determining the actual cleanliness of the sewage in the dishwasher in the current washing stage is the same as the method of determining the actual cleanliness of the sewage in the dishwasher in the previous washing stage, which will not be repeated here.

[0109] Step S704, when the actual cleanliness does not meet the cleaning condition, the amount of detergent added in the current washing stage is updated according to the numerical difference between the actual cleanliness and the expected cleanliness in the current washing stage, and the amount of detergent added in the next washing stage is determined.

[0110] The cleaning condition refers to a standard condition of cleanliness. For example, the cleaning condition may be a cleanliness of 0.01%.

[0111] Specifically, if the actual cleanliness of the current washing stage does not meet the final cleaning conditions, that is, the washing process of the current washing stage does not clean the dishes and meet the cleaning standards, it is still necessary to update the amount of detergent added in the current washing stage based on the numerical difference between the actual cleanliness and the expected cleanliness of the current washing stage, and determine the amount of detergent added in the next washing stage.

[0112] Step S706, taking the next washing stage as the current washing stage, returning to the step of adding detergent according to the amount of detergent added in the current washing stage and washing the dishes until the actual cleanliness of the sewage in the dishwasher meets the cleaning condition.

[0113] Specifically, the washing processes of the previous washing stage and the current washing stage have been completed and have not met the cleaning conditions. Therefore, the next washing stage needs to be taken as the current washing stage, and the process returns to the step of adding detergent according to the amount of detergent added in the current washing stage and washing the dishes (step S702), until the actual cleanliness of the sewage in the dishwasher meets the cleaning conditions, which means that the dishes in the dishwasher have been cleaned and meet the washing standards, thereby ensuring the normal operation of the dishwasher washing process.

[0114] In one embodiment, the dishwasher intelligent washing control method further includes the following steps:

[0115] Determine the fan speed of the dryer fan according to the number of dishes.

[0116] Among them, the fan is used to rotate to generate wind power to dry the tableware.

[0117] The dryer in the dishwasher refers to the drying function of the dishwasher. Its function is to remove moisture from the tableware through different drying techniques after the cleaning process is completed to keep the tableware dry and prevent bacterial growth.

[0118] The fan in the dryer is an important part of the dryer. Its function is to generate high-speed airflow to help the hot air pass through the clothes evenly and improve the drying efficiency. The speed of the fan has a direct impact on the drying effect. The appropriate speed helps to ensure that the hot air is fully in contact with the clothes, thereby achieving uniform drying. If the speed is too fast, it may cause the clothes to be entangled or damaged; if the speed is too slow, it may prolong the drying time and affect the drying effect.

[0119] The speed of a fan is a physical quantity that describes the number of revolutions the fan makes per unit time, usually expressed in revolutions per minute (RPM).

[0120] Specifically, the drying program in the existing dishwasher is set with a fixed fan speed, which automatically stops when the time is reached. When there are few dishes, the dishes have been dried but the drying program has not yet ended. When there are too many dishes, the drying effect is not ideal. Therefore, the fan speed can be automatically adjusted according to the number of dishes to make the drying effect uniform (consistent drying rate), ensure the same drying time for the dishes, and reduce the drying power.

[0121] In one embodiment, the fan speed of the fan in the dryer is determined according to the amount of feed, which can be as follows: Figure 8 As shown, the following steps are included:

[0122] Step S802, obtaining the association condition between the preset number of dishes and the fan speed of the fan in the dryer.

[0123] Specifically, association conditions between different numbers of tableware and the fan speed of the fan in the dryer can be set in advance, so that the fan speed of the fan in the dryer can be determined later based on the number of tableware in actual conditions.

[0124] Step S804, mapping the number of dishes to the associated conditions, and determining the fan speed corresponding to the number of dishes.

[0125] In the above steps, the association condition between the number of dishes and the fan speed of the dryer fan has been pre-established, so the fan speed of the dryer fan can be determined by simply mapping the known number of dishes in this washing process to the association condition. By adopting the method in this embodiment, the fan speed of the dryer fan can be accurately adjusted based on the number of dishes, thereby improving the drying effect.

[0126] In a specific embodiment, a dishwasher intelligent washing control method is also provided, including: to ensure that the dishwasher is washed clean, regardless of the number of dishes, the amount of water intake is fixed each time, the amount of dishwashing powder and rinse agent (detergent) added is also fixed, and the water intake and addition are based on the maximum value. In the case that there are too few dishes in reality, it is not necessary to add the maximum amount.

[0127] Pre-washing stage: Through research, it is found that Fig. 9 As shown in the figure: Under the same water intake and the same washing pump speed, different numbers of tableware will affect the water heating speed. The more tableware there are, the more serious the oil pollution is, resulting in a slower rise in water temperature. By comparing N groups of data, the number of tableware can be determined by the water temperature rise time. Therefore, in the pre-wash stage, the amount of rinse aid and dishwashing powder can be adjusted according to the number of tableware. At the end of the pre-wash, the cleanliness of the sewage is tested, and the actual cleanliness Ux is recorded, and Ux is compared with Ua (expected cleanliness).

[0128] Main wash stage: According to the number of dishes determined in the pre-wash stage, adjust the amount of detergent added. At the same time, when Ux≤Ua, reduce the amount added based on the previous wash stage. Otherwise, increase the amount added. After washing, check the cleanliness Ux again and compare Ux with Ub (cleaning conditions). When Ux>Ub, it means that it is not clean and needs to be washed again. Repeat the washing steps until Ux≤Ub, and then end the main wash. Targeted placement of these consumables according to the number of dishes and the oil stains can reduce the use of consumables and the amount of water used for dishwashing.

[0129] Drying stage: The original drying program sets the fan speed to a fixed level, and it stops automatically when the time is reached. This may result in the tableware being dried when there are few dishes but the drying program is not finished. If there are too many dishes, the drying effect is not ideal. Figure 1 As shown: the existing program automatically adjusts the fan speed according to the number of dishes while ensuring the same drying time for the dishes, so that the drying effect is uniform (the drying rate is consistent), the drying power is reduced, and the drying time is shortened.

[0130] Specific implementation: Fig.10 As shown:

[0131] Select the smart wash mode and start water inlet operation, enter the pre-wash stage, the washing pump is activated and the heating plate is working, record the time required for the water temperature to rise from 25℃ to 35℃, the time is t, there are three situations: ①t≤t1, ②t1<t≤t2, ③t2<t≤t3, such as Fig. 9 It is known that when the least amount of dishes is put in, the time required to heat the water to the target temperature is t1, when the medium amount of dishes is put in, the time required to heat the water to the target temperature is t2, and when the maximum amount of dishes is put in, the time required to heat the water to the target temperature is t3. In cases ①, ②, and ③, put in the corresponding consumables such as rinse aid and dishwashing powder at the required gear (Note that the number of dishes corresponding to cases ①, ②, and ③ here is small, medium, and large. If necessary, it can be subdivided and divided into more gears). Wash until the pre-wash stage is over.

[0132] After the pre-wash, the main wash phase begins. The actual cleanliness Ux of the pre-wash phase is determined first, and Ux is compared with the expected cleanliness Ua. According to the numerical difference between Ux and Ua, the corresponding water intake and the amount of rinse agent and dishwashing powder are adjusted based on situations ①, ②, and ③ respectively (Situation ①: The water intake is B1, and the amount of rinse agent and dishwashing powder is appropriately adjusted based on C1 and D1; Situation ②: The water intake is B2, and the amount of rinse agent and dishwashing powder is appropriately adjusted based on C2 and D2; Situation ③: The water intake is B3, and the amount of rinse agent and dishwashing powder is appropriately adjusted based on C3 and D3). After washing, the actual cleanliness Ux is detected again, and Ux is compared with Ub (cleaning conditions). When Ux>Ub, it means that it is not clean and needs to be washed again. Repeat the washing steps until Ux≤Ub, and the main wash ends. Targeted placement of these consumables according to the number of tableware and the oil pollution can reduce the use of consumables and the amount of water used for dishwashing.

[0133] After the main wash, the drying phase begins. Fig.11 , it is known that in the drying stage, under the same number of dishes, the faster the fan speed W, the faster the drying rate; under the same speed W, the more dishes there are, the slower the drying rate. Cases ①, ②, and ③ correspond to speeds W1, W2, and W3 respectively (the drying speeds of cases ①, ②, and ③ are determined based on the corresponding number of dishes A1, A2, and A3, respectively), and continue drying until the drying stage ends and the washing ends.
