In order to reduce the scale generated during the washing process, dishwashers are usually equipped with a resin chamber for accommodating renewable resins. After entering the dishwasher, the water will first pass through the resin chamber, and the ion exchange capacity of the resin will be used to soften the incoming water, thereby reducing the scale generated during the washing process. The ion exchange capacity of the resin will decrease after a certain period of use. At this time, high-concentration recycled water is needed to regenerate the resin. After the resin is regenerated, the resin chamber needs to be rinsed to remove the high-concentration recycled water.

[0003] In the related art, a fixed flushing procedure is usually used for flushing, that is, a fixed flushing water volume is used to flush the resin cavity. However, the fixed flushing procedure sometimes under-flushes and sometimes over-flushes, resulting in poor flushing effect on the resin cavity. Summary of the invention

[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0026] In this application, the terms "first", "second", etc. are used to distinguish identical or similar items with basically the same effects and functions. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor is there any limitation on quantity and execution order.

[0027] Dishwasher: A dishwasher is a machine that uses chemical, mechanical, thermal and electrical methods to wash, rinse and dry tableware such as bowls, plates, glassware, cutlery and cooking utensils.

[0028] Water quality sensor: A sensor used to measure water quality. In the embodiment of the present application, the water quality sensor includes a turbidity sensor and a conductivity sensor.

[0029] Resin: The resin commonly used in dishwashers is mainly ion exchange resin, which can absorb calcium and magnesium ions in water to prevent them from forming scale during the heating process, which affects the performance of the dishwasher. Ion exchange resin is usually made of recycled materials, such as certain types of polymers, which can be reused or recycled after use to reduce environmental pollution and waste of resources.

[0030] After the resin is saturated with adsorption, high-concentration regenerated water can be added for regeneration. The regeneration method is as follows:

[0031] Ca 2+ +2RNa=R2Ca+2Na + ;

[0032] Mg 2+ +2RNa=R2Mg+2Na + ;

[0033] Among them, Ca 2+ and Mg 2+ It is an ion adsorbed by the resin. RNa is the main component of high-concentration regenerated water. The regeneration process is to use Na + Replacement of Ca2+ adsorbed on resin 2+ and Mg 2+ After regeneration is completed, the high-concentration regenerated water needs to be flushed away to prevent the generation of a large amount of scale.

[0034] In the related art, a fixed flushing procedure is usually used to flush high-concentration recycled water. However, if the flushing is insufficient, the washing water will contain a large amount of hardness ions and salts, which is very likely to produce scale and white spots; if a large amount of flushing is performed, it will not only waste water but also the adsorption capacity of the resin, after all, the water is also softened during the flushing process. The technical solution provided in the embodiment of the present application can improve this problem and improve the flushing effect.

[0035] Figure 1 is a structural schematic diagram of a dishwasher provided in an embodiment of the present application, see Figure 1The dishwasher 100 includes a water inlet pipe 101, a resin chamber 102, a first connecting pipe 103, a water cup 104, a second connecting pipe 105, a water pump 106 and an inner tank 107. The water inlet pipe 101 is connected to a water source, and water enters the dishwasher 100 through the water inlet pipe 101. The resin chamber 102 is used to contain resin, which can soften water and reduce the content of calcium and magnesium ions in water to prevent the formation of scale, ensure the normal operation of the dishwasher and extend its service life. The first connecting pipe 103 is used to connect the resin chamber and the water cup 104, and the water in the resin chamber 102 can enter the water cup 104 through the first connecting pipe 103. The water cup 104 is the bottom of the inner tank 107 of the dishwasher 100. The inner tank 107 is used to hold cleaned tableware. The second connecting pipe 105 is used to connect the water cup 104 and the water pump 106. The water pump 106 can pump the water in the water cup 104 into the inner tank 107 to clean or rinse the tableware in the inner tank 107.

[0036] In the embodiment of the present application, when the resin in the resin chamber 102 needs to be regenerated, high-concentration regeneration water is injected into the resin chamber 102, and the calcium and magnesium ions adsorbed in the resin are replaced by the sodium ions in the high-concentration regeneration water, thereby achieving the regeneration of the resin. After the resin is regenerated, the resin chamber 102 needs to be flushed to remove the high-concentration regeneration water in the resin chamber 102. The technical solution provided in the embodiment of the present application is applied to the process of flushing the resin chamber 102.

[0037] After introducing the structural diagram of the dishwasher provided in the embodiment of the present application, the implementation environment of the embodiment of the present application is introduced below. Figure 2 Schematic diagram of the implementation environment of a method for flushing a resin cavity of a dishwasher provided in an embodiment of the present application, see Figure 2 The implementation environment includes a controller 201 and a water quality sensor 202 of the dishwasher. The controller 201 is electrically connected to the water quality sensor 202 and the water inlet sensor 203, and the controller 201 can obtain data collected by the water quality sensor 202 and the water inlet sensor 203. The water quality sensor 202 is used to measure the water quality value of the water in the dishwasher, and the water quality value can reflect the quality of the water in the dishwasher. In some embodiments, see Figure 1 The water quality sensor 202 is installed in the water cup 104 of the dishwasher. In the embodiment of the present application, the controller 201 can use the data collected by the water quality sensor 202 to control the dishwasher and improve the effect of flushing the resin cavity.

[0038] After introducing the implementation environment of the embodiment of the present application, the application scenario of the embodiment of the present application will be described below. The technical solution provided by the embodiment of the present application can be applied to various types of dishwashers. After adopting the technical solution provided by the embodiment of the present application, when the resin of the dishwasher is regenerated, it is determined whether the resin cavity needs to be flushed according to the amount of high-concentration regenerated water remaining in the resin cavity. In the case where the resin cavity needs to be flushed, the first flushing parameter for flushing the resin cavity is determined according to the amount of high-concentration regenerated water remaining in the resin cavity. The first flushing parameter is a flushing parameter that matches the residual amount of high-concentration regenerated water in the resin cavity. Flushing the resin cavity using the first flushing parameter can improve the flushing effect.

[0039] Figure 3 is a flow chart of a method for flushing a resin cavity of a dishwasher provided in an embodiment of the present application, see Figure 3 , taking the controller of a dishwasher as an example, the method includes:

[0040] 301. When the resin of the dishwasher is regenerated, the controller determines whether the resin cavity needs to be flushed based on a first regeneration residual parameter of the resin cavity of the dishwasher, where the first regeneration residual parameter is used to indicate the amount of high-concentration regeneration water remaining in the resin cavity.

[0041] Among them, the completion of resin regeneration means that the reaction between the high-concentration regenerated water and the resin is completed, and the resin restores the ability to soften the incoming water, that is, restores the adsorption of Ca in the incoming water. 2+ and Mg 2+ In the embodiment of the present application, the first regeneration residual parameter is positively correlated with the residual amount of high-concentration regenerated water, that is, the more the residual amount of high-concentration regenerated water in the resin chamber, the larger the first regeneration residual parameter; the less the residual amount of high-concentration regenerated water in the resin chamber, the smaller the first regeneration residual parameter. Accordingly, the basis for judging whether the resin chamber needs to be flushed is the residual amount of high-concentration regenerated water, thereby realizing intelligent flushing judgment and preventing insufficient flushing and excessive flushing.

[0042] It should be noted that, when the resin is regenerated, multiple rounds of flushing of the resin chamber may be performed. For ease of understanding, the embodiment of the present application is described using one round of flushing as an example.

[0043] 302. When the resin cavity needs to be flushed, the controller determines a first flushing parameter for flushing the resin cavity based on the first regeneration residual parameter, where the first flushing parameter includes a flushing water volume and / or a flushing flow rate.

[0044] Among them, the need to flush the resin cavity means that there is a large amount of residual high-concentration regenerated water in the resin cavity. Flushing the resin cavity can reduce the residual amount of high-concentration regenerated water. The flushing water volume refers to the amount of water used to flush the resin cavity. The more flushing water volume, the more high-concentration regenerated water can be taken away in a single flush. The flushing flow rate refers to the speed at which the incoming water flows through the resin cavity. The greater the flushing flow rate, the greater the flushing intensity, and the more precipitation can be taken away. In an embodiment of the present application, the flushing parameters are determined based on the amount of high-concentration regenerated water remaining in the resin cavity. Therefore, the flushing parameters are more consistent with the actual situation in the resin cavity after the resin regeneration is completed.

[0045] 303. The controller controls the dishwasher to rinse the resin cavity based on the first rinse parameter.

[0046] Among them, flushing the resin cavity is to use the inlet water of the dishwasher to flow through the resin cavity. The high-concentration regenerated water in the resin cavity will mix with the inlet water and flow out of the resin cavity. The high-concentration regenerated water will be diluted by the inlet water, thereby reducing the residual amount of high-concentration regenerated water in the resin cavity.

[0047] Through the technical solution provided by the embodiment of the present application, when the resin of the dishwasher is regenerated, it is determined whether the resin cavity needs to be flushed according to the amount of high-concentration regenerated water remaining in the resin cavity. When it is necessary to flush the resin cavity, a first flushing parameter for flushing the resin cavity is determined according to the amount of high-concentration regenerated water remaining in the resin cavity, and the first flushing parameter is a flushing water volume / flushing flow rate that matches the residual amount of high-concentration regenerated water in the resin cavity. The resin cavity is flushed using the first flushing parameter to prevent insufficient flushing and excessive flushing, thereby improving the flushing effect.

[0048] The above steps 301-303 are a brief introduction to the method for flushing the resin cavity of the dishwasher provided in the embodiment of the present application. The technical solution provided in the embodiment of the present application will be more clearly explained below with reference to some examples. Figure 4 Taking the controller of a dishwasher as an example, the method includes the following steps.

[0049] 401. When the resin of the dishwasher is completely regenerated, the controller determines a first regeneration residual parameter of the resin cavity of the dishwasher, where the first regeneration residual parameter is used to indicate the amount of high-concentration regeneration water remaining in the resin cavity.

[0050] Among them, the completion of resin regeneration means that the reaction between the high-concentration regenerated water and the resin is completed, and the resin restores the ability to soften the incoming water, that is, restores the adsorption of Ca in the incoming water. 2+ and Mg 2+Capacity. In the embodiment of the present application, the first regeneration residual parameter is positively correlated with the residual amount of high-concentration regenerated water, that is, the more the residual amount of high-concentration regenerated water in the resin chamber, the larger the first regeneration residual parameter. The less the residual amount of high-concentration regenerated water in the resin chamber, the smaller the first regeneration residual parameter. In addition, resin regeneration is a process in which the resin and the high-concentration regenerated water undergo a replacement reaction. Whether the resin regeneration is completed is usually determined by the duration of the replacement reaction between the resin and the high-concentration regenerated water. When the duration of the replacement reaction between the resin and the high-concentration regenerated water reaches a preset duration, the resin regeneration is determined to be completed; when the duration of the replacement reaction between the resin and the high-concentration regenerated water does not reach the preset duration, the resin is determined to be incompletely regenerated. The preset duration is set by the technician according to the actual situation, such as being set to 30 minutes, and the embodiment of the present application does not limit this.

[0051] In a possible implementation, the controller obtains a first water quality value of the water in the resin chamber and an initial water quality value of the inlet water of the dishwasher, and determines a first regeneration residual parameter of the resin chamber based on the first water quality value and the initial water quality value.

[0052] Among them, the first water quality value is the water quality value of the water in the resin cavity after the resin regeneration is completed, reflecting the water quality of the water in the resin cavity. The initial water quality value can reflect the water quality of the incoming water, which is equivalent to the benchmark for judging the high-concentration regenerated water. The first regeneration residual parameter is determined by using the first water quality value and the initial water quality value. The first residual parameter has a high accuracy. In some embodiments, the water quality value includes conductivity, which is closely related to the concentration of ions in the water. In the embodiment of the present application, the high-concentration regenerated water has a high ion (Na2O3) before and after the resin regeneration. + , Cl - , Ca 2+ Mg 2+ ) concentration, the residual amount of high-concentration recycled water can be inferred by conductivity. Accordingly, in the case where the water quality value includes conductivity, the water quality sensor of the dishwasher includes a conductivity sensor, and accordingly, the first water quality value is the first conductivity, and the initial water quality value is the initial conductivity. For example, the conductivity sensor is a TDS (Total Dissolved Solids) sensor. In other embodiments, the water quality value also includes turbidity. During the resin regeneration process, some crystals will precipitate, and these crystals will affect the turbidity of the water. In the embodiment of the present application, these crystals can also be regarded as additional residues of high-concentration recycled water, and the amount of crystals can be inferred by turbidity. Accordingly, in the case where the water quality value includes turbidity, the water quality sensor of the dishwasher includes a turbidity sensor, and accordingly, the first water quality value is the first turbidity, and the initial water quality value is the initial turbidity. For example, the turbidity sensor is a spectral sensor.

[0053] In order to illustrate the above-mentioned embodiment, the above-mentioned embodiment is described below through several examples.

[0054] Example 1: The controller obtains a first water quality value of the water in the resin cavity and an initial water quality value of the inlet water of the dishwasher through a water quality sensor. The controller divides the first water quality value by the initial water quality value to obtain the first regeneration residual parameter.

[0055] In some embodiments, the water quality sensor is installed in the resin cavity, so that the initial water quality value can be measured before adding the regeneration concentrated water, and the first water quality value of the water in the resin cavity can be measured when the resin regeneration is completed. In other embodiments, some dishwashers have and only have a water quality sensor configured in the water cup. Since the resin cavity is connected to the water cup, the water passing through the resin cavity will flow into the water cup, so the water quality sensor in the water cup can also be used to measure the first water quality value and the initial water quality value. For example, before adding the regeneration concentrated water, the dishwasher is controlled to enter water, and the controller obtains the initial water quality value of the entering water through the water quality sensor in the water cup. When the resin regeneration is completed, the dishwasher is controlled to enter a preset amount of water, so that a small amount of water in the resin cavity is flushed into the water cup, and the controller obtains the first water quality value through the water quality sensor in the water cup. The preset water volume is set by the technician according to the actual situation, and the embodiment of the present application is not limited to this. Under this setting, whether the dishwasher is configured with a water quality sensor in the resin cavity alone, the first water quality value and the second water quality value can be obtained, which greatly improves the scope of application of the technical solution provided in the embodiment of the present application.

[0056] In this embodiment, the ratio between the first water quality value and the initial water quality value is determined as the first regeneration residual parameter, which can intuitively reflect the deviation between the water in the resin chamber after resin regeneration and the inlet water, thereby reflecting the amount of residual high-concentration regeneration water.

[0057] Example 2: The controller obtains the first water quality value of the water in the resin cavity and the initial water quality value of the inlet water of the dishwasher through the water quality sensor. The controller divides the first water quality value by the initial water quality value and adds the result to the water quality correction coefficient to obtain the first regeneration residual parameter. The water quality correction coefficient is determined by the water quality value of the area where the dishwasher is located.

[0058] Among them, the setting of the water quality correction coefficient takes into account that the difference in water quality in different regions will affect the final judgment result. For example, the initial water quality value of region A is 100, and the current first water quality value is measured to be 140. The ratio of the first water quality value to the initial water quality value is 1.4, and the difference between the first water quality value and the initial water quality value is 40. If the initial water quality value of region B is 500, the current first water quality value is measured to be 700, and the ratio of the first water quality value to the initial water quality value is 1.4, and the difference between the first water quality value and the initial water quality value is 200. Therefore, the difference between the water quality values ​​under the same ratio may be very large. The water quality correction coefficient is set here to correct this problem. For example, the water quality correction coefficient can be set to 0.3 in regions with high initial water quality values, and the water quality correction coefficient can be set to 0 in regions with low initial water quality values. In the embodiment of the present application, the corresponding relationship between the water quality correction coefficient and the water quality value of the region is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. Since the initial water quality value can be regarded as the water quality value of the area, the water quality correction coefficient can be obtained by querying the initial water quality value.

[0059] Example 3: The controller obtains a first water quality value of the water in the resin cavity and an initial water quality value of the inlet water of the dishwasher through a water quality sensor. The controller subtracts the first water quality value from the initial water quality value to obtain the first regeneration residual parameter.

[0060] In this embodiment, the difference between the first water quality value and the initial water quality value is determined as the first regeneration residual parameter, which can intuitively reflect the deviation between the water in the resin chamber after resin regeneration and the inlet water, thereby reflecting the amount of residual high-concentration regeneration water.

[0061] Another implementation of the above step 401 is described below.

[0062] In a possible implementation, the controller obtains a first water quality value of the water in the resin chamber and a third water quality value of the high-concentration regenerated water added to the resin chamber, and determines a first regeneration residual parameter of the resin chamber based on the first water quality value and the third water quality value.

[0063] Among them, the third water quality value is the water quality value of the water in the resin cavity when the resin starts to regenerate, reflecting the water quality of the high-concentration regenerated water.

[0064] In order to illustrate the above-mentioned embodiment, the above-mentioned embodiment is described below through several examples.

[0065] Example 1: The controller obtains a first water quality value of the water in the resin cavity and a third water quality value of the high-concentration regenerated water added to the resin cavity through a water quality sensor. The controller divides the first water quality value by the third water quality value to obtain the first regeneration residual parameter.

[0066] In this way, the larger the first regeneration residual parameter is, the larger the first water quality value is, and the more high-concentration regeneration water remains in the resin chamber. The smaller the first regeneration residual parameter is, the smaller the first water quality value is, and the less high-concentration regeneration water remains in the resin chamber.

[0067] Example 2: The controller obtains the first water quality value of the water in the resin cavity and the third water quality value of the high-concentration regenerated water added to the resin cavity through the water quality sensor. The controller subtracts the third water quality value from the first water quality value to obtain a water quality value difference. The controller determines the reciprocal of the water quality value difference as the first regeneration residual parameter.

[0068] In this way, the larger the first regeneration residual parameter is, the smaller the water quality value difference is, and the more high-concentration regeneration water remains in the resin chamber. The smaller the first regeneration residual parameter is, the larger the water quality value difference is, and the less high-concentration regeneration water remains in the resin chamber.

[0069] 402. The controller determines whether the resin cavity needs to be flushed based on a first regeneration residual parameter of the resin cavity of the dishwasher.

[0070] Among them, the basis for judging whether the resin cavity needs to be flushed is the residual amount of high-concentration recycled water, thereby realizing intelligent flushing judgment and preventing insufficient flushing and excessive flushing.

[0071] It should be noted that, when the resin is regenerated, multiple rounds of flushing of the resin chamber may be performed. For ease of understanding, the embodiment of the present application is described using one round of flushing as an example.

[0072] In a possible implementation, when the first regeneration residual parameter is less than the first parameter threshold, the controller determines that the resin chamber does not need to be flushed. When the first regeneration residual parameter is greater than or equal to the first parameter threshold, the controller determines that the resin chamber needs to be flushed.

[0073] Among them, if the first regeneration residual parameter is less than the first parameter threshold, it means that the residual amount of high-concentration regenerated water in the resin cavity is small, so the resin cavity does not need to be flushed to avoid over-flushing and save water; if the first regeneration residual parameter is greater than or equal to the first parameter threshold, it means that the residual amount of high-concentration regenerated water in the resin cavity is large, so the resin cavity needs to be flushed to avoid over-flushing and insufficient flushing, which affects the life of the dishwasher and the dishwashing effect. The first parameter threshold is set by the technician according to the actual situation, and the embodiment of the present application does not limit this.

[0074] Optionally, after step 402, the controller executes the following steps 403 and 404, or executes the following steps 405-409 according to actual conditions, which is not limited in the embodiment of the present application.

[0075] 403. When the resin cavity needs to be flushed, the controller determines a first flushing parameter for flushing the resin cavity based on the first regeneration residual parameter, where the first flushing parameter includes a flushing water volume and / or a flushing flow rate.

[0076] Among them, the need to flush the resin cavity means that there is a large amount of residual high-concentration regenerated water in the resin cavity. Flushing the resin cavity can reduce the residual amount of high-concentration regenerated water. The flushing water volume refers to the amount of water used to flush the resin cavity. The more flushing water volume, the more high-concentration regenerated water can be taken away in a single flush. The flushing flow rate refers to the speed at which the incoming water flows through the resin cavity. The greater the flushing flow rate, the greater the flushing intensity, and the more precipitation can be taken away. In an embodiment of the present application, the flushing parameters are determined based on the amount of high-concentration regenerated water remaining in the resin cavity. Therefore, the flushing parameters are more consistent with the actual situation in the resin cavity after the resin regeneration is completed.

[0077] In a possible implementation, when the resin cavity needs to be flushed and the first regeneration residual parameter is greater than or equal to the first parameter threshold value and less than or equal to the second parameter threshold value, the controller determines the flushing water volume as the first water volume, and / or the controller determines the flushing flow rate as the first flow rate. When the first regeneration residual parameter is greater than the second parameter threshold value, the controller determines the flushing water volume as the second water volume, and / or the controller determines the flushing flow rate as the second flow rate, the second water volume is greater than the first water volume, and the second flow rate is greater than the first flow rate.

[0078] Among them, the principle of determining the first flushing parameter based on the first regeneration residual parameter is that if the first regeneration residual parameter is large, it indicates that the residual amount of high-concentration regenerated water in the resin cavity is large, so a larger flushing water volume and / or flushing flow rate can be used to flush the resin cavity, thereby improving the effect of a single flushing of the resin cavity. If the first regeneration residual parameter is small, it indicates that the residual amount of high-concentration regenerated water in the resin cavity is small, so a smaller flushing water volume and / or flushing flow rate can be used to flush the resin cavity, thereby achieving flushing of the resin cavity while saving resources. The first parameter threshold, the second parameter threshold, the first flow rate, the second flow rate, the first water volume and the second water volume are set by technical personnel according to actual conditions, or determined in the following manner, and the embodiments of the present application are not limited to this.

[0079] In some embodiments, when the resin chamber needs to be flushed, the controller obtains the type of high-concentration regenerated water and determines the first parameter threshold, the second parameter threshold, the first flow rate, the second flow rate, the first water volume, and the second water volume corresponding to the type.

[0080] The type of high-concentration recycled water includes the common name, customary name, former name, code name and other identification of high-concentration recycled water. In some embodiments, before performing resin regeneration, the controller determines the type selected by the user as the type of high-concentration recycled water. For example, in response to the start instruction of the resin regeneration function, the controller displays a type acquisition interface through the display screen of the dishwasher, and the type acquisition interface is used to obtain the type of high-concentration recycled water used when regenerating the resin. In response to the type input operation or type selection operation on the type acquisition interface, the controller obtains the type of high-concentration recycled water.

[0081] In addition, the correspondence between the type and the first parameter threshold, the second parameter threshold, the first flow rate, the second flow rate, the first water volume and the second water volume is set by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0082] Another implementation of the above step 403 is described below.

[0083] In a possible implementation, when the resin cavity needs to be flushed, the controller inputs the first regeneration residual parameter into a first flushing parameter prediction model, extracts features of the first regeneration residual parameter through the first flushing parameter prediction model, and obtains a first parameter feature of the first regeneration residual parameter. The controller determines the first flushing parameter through the first flushing parameter prediction model based on the first parameter feature.

[0084] The first flushing parameter prediction model is a regression model that can map the input first regeneration residual parameter to the corresponding first flushing parameter. The embodiment of the present application does not limit the structure of the first flushing parameter prediction model. In the process of training the first flushing parameter prediction model, multiple sample regeneration residual parameters and the labeled flushing parameters corresponding to each sample regeneration residual parameter are used to train the first flushing parameter prediction model, and the labeled flushing parameters are the true values ​​predicted by the model.

[0085] In this implementation, the first flushing parameter prediction model is used to predict the flushing parameters, so as to give full play to the generalization ability of the first flushing parameter prediction model and improve the efficiency of flushing parameter determination.

[0086] For example, when the resin cavity needs to be flushed, the controller inputs the first regeneration residual parameter into the first flushing parameter prediction model, and performs multiple full connections on the first regeneration residual parameter through the first flushing parameter prediction model to obtain the first parameter feature of the first regeneration residual parameter. The controller performs full connections and normalization on the first parameter feature through the first flushing parameter prediction model to obtain the flushing water volume and / or flushing flow rate in the first flushing parameter.

[0087] For example, when it is necessary to flush the resin cavity, the controller inputs the first regeneration residual parameter into the first flushing parameter prediction model, and performs multiple full connections on the first regeneration residual parameter through the first flushing parameter prediction model to obtain the first parameter characteristic of the first regeneration residual parameter. The controller performs full connection and normalization on the first parameter characteristic through the water volume prediction unit of the first flushing parameter prediction model to obtain the flushing water volume in the first flushing parameter. The controller performs full connection and normalization on the first parameter characteristic through the flow rate prediction unit of the first flushing parameter prediction model to obtain the flushing flow rate in the first flushing parameter.

[0088] Another implementation of the above step 403 is described below.

[0089] In a possible implementation, when the resin cavity needs to be flushed, the controller uses the first regeneration residual parameter to query the first relationship table to obtain a first flushing parameter for flushing the resin cavity.

[0090] Among them, the first relationship table stores multiple regeneration residual parameters and flushing parameters corresponding to each regeneration residual parameter. The correspondence between the regeneration parameters and the flushing parameters in the first relationship table is set by technical personnel according to actual conditions, and the embodiment of the present application does not limit this.

[0091] In this implementation manner, by querying the first relationship table using the first regeneration residual parameter, the corresponding first flushing parameter can be obtained, and the determination efficiency of the first flushing parameter is relatively high.

[0092] Optionally, based on the above implementation, the controller can also perform the following steps.

[0093] In some embodiments, when the first flushing parameter corresponding to the first regeneration residual parameter is not stored in the first relationship table, the controller determines the first reference residual parameter and the second reference residual parameter from the first relationship table, the first reference residual parameter is less than the first regeneration residual parameter, the second reference residual parameter is greater than the first regeneration residual parameter, and among the residual parameters less than the first regeneration residual parameter in the first relationship table, the difference between the first reference residual parameter and the first regeneration residual parameter is the smallest; among the residual parameters greater than the first regeneration residual parameter in the first relationship table, the difference between the second reference residual parameter and the first regeneration residual parameter is the smallest. The controller determines the average value of the first reference flushing parameter corresponding to the first reference residual parameter and the second reference flushing parameter corresponding to the second reference residual parameter as the first flushing parameter corresponding to the first regeneration residual parameter.

[0094] 404. The controller controls the dishwasher to rinse the resin cavity based on the first rinse parameter.

[0095] Among them, flushing the resin cavity is to use the inlet water of the dishwasher to flow through the resin cavity. The high-concentration regenerated water in the resin cavity will mix with the inlet water and flow out of the resin cavity. The high-concentration regenerated water will be diluted by the inlet water, thereby reducing the residual amount of high-concentration regenerated water in the resin cavity.

[0096] In a possible implementation, when the first flushing parameter includes a flushing water volume, the controller controls water intake into the dishwasher, and when the water intake reaches the flushing water volume, the controller controls the dishwasher to stop intake of water to complete the current flushing round.

[0097] Among them, a solenoid valve and a water inlet sensor are arranged on the water inlet pipe of the dishwasher. The water inlet of the dishwasher can be controlled by the solenoid valve, and the water inlet amount can be obtained by the water inlet sensor.

[0098] In a possible implementation, when the first flushing parameter includes a flushing flow rate, the controller controls the dishwasher to intake water at the flushing flow rate, and when the water intake reaches a preset water intake, the controller controls the dishwasher to stop intake of water to complete the current flushing round.

[0099] A water pump is provided between the water inlet pipe and the resin cavity, or between the resin cavity and the water cup, and the flushing flow rate can be controlled by the water pump. The preset water inlet volume is the water inlet volume set by the technician according to the actual situation, and the embodiment of the present application does not limit this.

[0100] Through the above steps 401-404, when the resin of the dishwasher is regenerated, it is determined whether the resin cavity needs to be flushed according to the amount of high-concentration regenerated water remaining in the resin cavity. When the resin cavity needs to be flushed, a first flushing parameter for flushing the resin cavity is determined according to the amount of high-concentration regenerated water remaining in the resin cavity. The first flushing parameter is a flushing water volume / flushing flow rate that matches the residual amount of high-concentration regenerated water in the resin cavity. The resin cavity is flushed using the first flushing parameter to prevent insufficient flushing and excessive flushing, thereby improving the flushing effect.

[0101] Optionally, after the above step 404, the controller can also perform the following steps.

[0102] In a possible implementation, when the last round of rinsing is completed, the controller redetermines the first regeneration residual parameter of the resin chamber. Based on the redetermined first regeneration residual parameter, the controller determines whether it is necessary to rinse the resin chamber again. If it is necessary to rinse the resin chamber again, the controller controls the dishwasher to rinse the resin chamber again based on the redetermined first regeneration residual parameter. If it is not necessary to rinse the resin chamber again, the controller performs the following step 405.

[0103] It should be noted that after each round of rinsing is completed, the controller will control the dishwasher to drain, thereby discharging the remaining high-concentration recycled water from the dishwasher, while avoiding the judgment of whether to rinse again in the future.

[0104] In this implementation, after completing one round of flushing, it is also possible to determine whether the resin cavity needs to be flushed again, thereby avoiding insufficient flushing of the resin cavity and improving the efficiency of flushing the resin cavity.

[0105] For example, when the last round of flushing is completed, the controller reacquires the first water quality value of the water in the resin cavity. Based on the reacquired first water quality value and the initial water quality value, the controller redetermines the first regeneration residual parameter of the resin cavity. When the re-determined first regeneration residual parameter is less than the first parameter threshold, the controller determines that the resin cavity does not need to be flushed again. When the re-determined first regeneration residual parameter is greater than or equal to the first parameter threshold, the controller determines that the resin cavity needs to be flushed again. When the resin cavity needs to be flushed again, the controller determines the first flushing parameter for flushing the resin cavity again based on the re-determined first regeneration residual parameter. Based on the re-determined first flushing parameter, the controller controls the dishwasher to flush the resin cavity again. When the resin cavity does not need to be flushed again, the controller performs the following step 405.

[0106] 405. When flushing of the resin cavity is not required, the controller determines a second regeneration residual parameter of the water cup of the dishwasher, where the second regeneration residual parameter is used to indicate the amount of high-concentration regeneration water remaining in the water cup.

[0107] Among them, since the resin chamber is connected to the water cup, the high-concentration regenerated water entering the resin chamber will also pass through the water cup, causing residue in the water cup. In order to eliminate the residue in the water cup, the water cup needs to be rinsed. The second regeneration residual parameter is positively correlated with the residual amount of high-concentration regenerated water, that is, the more the residual amount of high-concentration regenerated water in the water cup, the larger the second regeneration residual parameter; the less the residual amount of high-concentration regenerated water in the water cup, the smaller the second regeneration residual parameter.

[0108] In a possible implementation, when the resin cavity does not need to be flushed, the controller controls the dishwasher to drain water. When the dishwasher is drained, the controller controls the dishwasher to refill water and obtain a second water quality value of the water in the water cup. The controller determines a second regeneration residual parameter of the resin cavity based on the second water quality value and the initial water quality value.

[0109] Similar to the first water quality value, the second water quality value is a second conductivity or a second turbidity.

[0110] In order to illustrate the above-mentioned embodiment, the above-mentioned embodiment is described below through several examples.

[0111] Example 1: When the resin cavity does not need to be flushed, the controller controls the dishwasher to drain water. When the dishwasher is drained, the controller controls the dishwasher to refill water and obtains the second water quality value of the water in the water cup through the water quality sensor. The controller divides the second water quality value by the initial water quality value to obtain the second regeneration residual parameter.

[0112] In some embodiments, the water quality sensor is installed in the water cup. When the resin cavity does not need to be flushed, the controller controls the dishwasher to drain water and flush water in, so that the second water quality value of the water in the water cup can be measured after the resin regeneration is completed.

[0113] In this embodiment, the ratio between the second water quality value and the initial water quality value is determined as the second regeneration residual parameter, which can intuitively reflect the deviation between the water in the water cup after resin regeneration and the incoming water, thereby reflecting the amount of residual high-concentration regeneration water.

[0114] Example 2: When the resin cavity does not need to be flushed, the controller controls the dishwasher to drain. When the dishwasher is drained, the controller controls the dishwasher to refill water and obtains the second water quality value of the water in the water cup through the water quality sensor. The controller divides the second water quality value by the initial water quality value and adds the water quality correction coefficient to obtain the second regeneration residual parameter, and the water quality correction coefficient is determined by the water quality value of the area where the dishwasher is located.

[0115] In this embodiment, the difference between the second water quality value and the initial water quality value is determined as the second regeneration residual parameter, which can intuitively reflect the deviation between the water in the water cup after resin regeneration and the inlet water, thereby reflecting the amount of residual high-concentration regeneration water.

[0116] Example 3: When the resin cavity does not need to be flushed, the controller controls the dishwasher to drain water. When the dishwasher is drained, the controller controls the dishwasher to refill water and obtains the second water quality value of the water in the water cup through the water quality sensor. The controller subtracts the second water quality value from the initial water quality value to obtain the second regeneration residual parameter.

[0117] Another implementation of the above step 401 is described below.

[0118] In a possible implementation, the controller obtains a second water quality value of the water in the water cup and a third water quality value of the high-concentration regenerated water added to the resin chamber, and determines a second regeneration residual parameter of the water cup based on the second water quality value and the third water quality value.

[0119] In order to illustrate the above-mentioned embodiment, the above-mentioned embodiment is described below through several examples.

[0120] Example 1: The controller obtains the second water quality value of the water in the water cup and the third water quality value of the high-concentration regenerated water added to the resin chamber through the water quality sensor. The controller divides the second water quality value by the third water quality value to obtain the second regeneration residual parameter.

[0121] In this way, the larger the second regeneration residual parameter is, the larger the second water quality value is, and the more high-concentration regeneration water remains in the water cup. The smaller the second regeneration residual parameter is, the smaller the second water quality value is, and the less high-concentration regeneration water remains in the water cup.

[0122] Example 2: The controller obtains the second water quality value of the water in the water cup and the third water quality value of the high-concentration regenerated water added to the resin chamber through the water quality sensor. The controller subtracts the third water quality value from the second water quality value to obtain a water quality value difference. The controller determines the reciprocal of the water quality value difference as the second regeneration residual parameter.

[0123] In this way, the larger the second regeneration residual parameter is, the smaller the water quality value difference is, and the more high-concentration regeneration water remains in the water cup. The smaller the second regeneration residual parameter is, the larger the water quality value difference is, and the less high-concentration regeneration water remains in the water cup.

[0124] 406. The controller determines whether the water cup needs to be rinsed based on the second regeneration residual parameter of the water cup of the dishwasher.

[0125] Among them, the basis for judging whether the water cup needs to be rinsed is the residual amount of high-concentration recycled water, thereby realizing intelligent rinsing judgment and preventing insufficient and excessive rinsing.

[0126] In a possible implementation, when the second regeneration residual parameter is greater than the third parameter threshold, the controller determines that the water cup needs to be rinsed. When the second regeneration residual parameter is less than or equal to the third parameter threshold, the controller determines that the water cup does not need to be rinsed.

[0127] Among them, the second regeneration residual parameter is less than the third parameter threshold, indicating that the residual amount of high-concentration recycled water in the water cup is small, so there is no need to rinse the water cup to avoid over-rinsing and save water; the second regeneration residual parameter is greater than or equal to the third parameter threshold, indicating that the residual amount of high-concentration recycled water in the water cup is large, so the water cup needs to be rinsed to avoid over-rinsing and insufficient washing, which affects the life of the dishwasher and the dishwashing effect. The third parameter threshold is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. In some embodiments, the third parameter threshold is less than the first parameter threshold.

[0128] Optionally, after step 406, the controller executes the following steps 407 and 408, or executes the following step 409 according to actual conditions, which is not limited in the embodiment of the present application.

[0129] 407. When the water cup needs to be rinsed, the controller determines a second rinse parameter, where the second rinse parameter includes a rinse water volume and / or a rinse flow rate.

[0130] Among them, the need to rinse the water cup means that there is a large amount of residual high-concentration recycled water in the water cup. Flushing the water cup can reduce the residual amount of high-concentration recycled water.

[0131] In a possible implementation, when the water cup needs to be rinsed, the controller determines the second rinse parameter based on the second regeneration residual parameter.

[0132] For example, when the water cup needs to be rinsed and the second regeneration residual parameter is greater than or equal to the third parameter threshold value, and less than or equal to the fourth parameter threshold value, the controller determines the rinsing water volume as the third water volume, and / or the controller determines the rinsing flow rate as the third flow rate. When the second regeneration residual parameter is greater than the fourth parameter threshold value, the controller determines the rinsing water volume as the fourth water volume, and / or the controller determines the rinsing flow rate as the fourth flow rate, the fourth water volume is greater than the third water volume, and the fourth flow rate is greater than the third flow rate.

[0133] Among them, the principle of determining the second flushing parameter based on the second regeneration residual parameter is that if the second regeneration residual parameter is large, it means that the residual amount of high-concentration regenerated water in the water cup is large, so a larger flushing water volume and / or flushing flow rate can be used to flush the water cup, thereby improving the effect of a single flush of the water cup. If the second regeneration residual parameter is small, it means that the residual amount of high-concentration regenerated water in the water cup is small, so a smaller flushing water volume and / or flushing flow rate can be used to flush the water cup, thereby achieving flushing of the water cup while saving resources. The fourth parameter threshold, the third flow rate, the fourth flow rate, the third water volume and the fourth water volume are set by the technician according to the actual situation, or determined by the following method, and the embodiments of the present application are not limited to this.

[0134] In some embodiments, when the water cup needs to be rinsed, the controller obtains the type of high-concentration regenerated water and determines the third parameter threshold, the fourth parameter threshold, the third flow rate, the fourth flow rate, the third water volume, and the fourth water volume corresponding to the type.

[0135] In some embodiments, when the water cup needs to be rinsed, the controller uses the second regeneration residual parameter to query the second relationship table to obtain the second rinse parameter for flushing the resin cavity.

[0136] Among them, the second relationship table stores multiple regeneration residual parameters and flushing parameters corresponding to each regeneration residual parameter. The correspondence between the regeneration parameters and the flushing parameters in the second relationship table is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. The second relationship table can be the same as the first relationship table or different from the first relationship table, and the embodiment of the present application does not limit this.

[0137] In this implementation, by using the second regeneration residual parameter to query the second relationship table, the corresponding second flushing parameter can be obtained, and the second flushing parameter is determined with high efficiency.

[0138] Optionally, based on the above implementation, the controller can also perform the following steps.

[0139] In some embodiments, when the second flushing parameter corresponding to the second regeneration residual parameter is not stored in the second relationship table, the controller determines a third reference residual parameter and a fourth reference residual parameter from the second relationship table, the third reference residual parameter is less than the second regeneration residual parameter, the fourth reference residual parameter is greater than the second regeneration residual parameter, and among the residual parameters in the second relationship table that are less than the second regeneration residual parameter, the difference between the third reference residual parameter and the second regeneration residual parameter is the smallest; among the residual parameters in the second relationship table that are greater than the second regeneration residual parameter, the difference between the fourth reference residual parameter and the second regeneration residual parameter is the smallest. The controller determines the average value of the third reference flushing parameter corresponding to the third reference residual parameter and the fourth reference flushing parameter corresponding to the fourth reference residual parameter as the second flushing parameter corresponding to the second regeneration residual parameter.

[0140] Another implementation of the above step 407 is described below.

[0141] In a possible implementation, when the water cup needs to be rinsed, the controller obtains the temperature in the water cup and determines the second rinsing parameter based on the temperature and the second regeneration residual parameter.

[0142] The temperature in the water cup is measured by a temperature sensor in the water cup.

[0143] In this embodiment, the temperature and the second regeneration residual parameter are used to determine the second flushing parameter, the second flushing parameter is more closely matched to the situation in the water cup, and the effect of flushing the water cup using the second flushing parameter is better.

[0144] For example, when the water cup needs to be rinsed, the controller obtains the temperature in the water cup through the temperature sensor. The controller inputs the temperature and the second regeneration residual parameter into the second rinsing parameter prediction model, and extracts the features of the temperature and the second regeneration residual parameter through the second rinsing parameter prediction model to obtain the second parameter feature. The controller determines the second rinsing parameter through the second rinsing parameter prediction model based on the second parameter feature.

[0145] The second flushing parameter prediction model is a regression model, and the input temperature and the second regeneration residual parameter are mapped to the corresponding second flushing parameter. The embodiment of the present application does not limit the structure of the second flushing parameter prediction model. In the process of training the second flushing parameter prediction model, multiple sample data and the labeled flushing parameters corresponding to each sample data are used to train the second flushing parameter prediction model. The labeled flushing parameters are the true values ​​predicted by the model. One sample data includes a pair of sample regeneration residual parameters and sample temperature.

[0146] For example, when it is necessary to rinse the water cup, the controller obtains the temperature in the water cup through the temperature sensor. The controller inputs the temperature and the second regeneration residual parameter into the second rinsing parameter prediction model, and performs multiple full connections on the temperature and the second regeneration residual parameter through the second rinsing parameter prediction model to obtain the second parameter feature. The controller performs full connection and normalization on the second parameter feature through the water volume prediction unit of the second rinsing parameter prediction model to obtain the rinsing water volume in the second rinsing parameter. The controller performs full connection and normalization on the second parameter feature through the flow rate prediction unit of the second rinsing parameter prediction model to obtain the rinsing flow rate in the second rinsing parameter.

[0147] Another implementation of the above step 407 is described below.

[0148] In a possible implementation, when the water cup needs to be rinsed, the controller determines a preset rinse parameter as the second rinse parameter, and the preset rinse parameter is a rinse parameter that matches the water cup.

[0149] Among them, the preset flushing parameters are set by technicians according to actual conditions, and the embodiments of the present application do not limit this.

[0150] 408. The controller controls the dishwasher to rinse the cup based on the second rinse parameter.

[0151] Among them, rinsing the water cup means using the inlet water of the dishwasher to flow through the water cup. The high-concentration recycled water in the water cup will mix with the inlet water and flow out of the water cup. The high-concentration recycled water will be diluted by the inlet water, thereby reducing the residual amount of high-concentration recycled water in the water cup.

[0152] In a possible implementation, when the second flushing parameter includes the flushing water volume, the controller controls the dishwasher to intake water, and when the intake water volume reaches the flushing water volume, the controller controls the dishwasher to stop intake water to complete the current flushing round.

[0153] Among them, a solenoid valve and a water inlet sensor are arranged on the water inlet pipe of the dishwasher. The water inlet of the dishwasher can be controlled by the solenoid valve, and the water inlet amount can be obtained by the water inlet sensor.

[0154] In a possible implementation, when the second flushing parameter includes a flushing flow rate, the controller controls the dishwasher to intake water at the flushing flow rate, and when the water intake reaches a preset water intake, the controller controls the dishwasher to stop intake water to complete the current flushing round.

[0155] A water pump is provided between the water inlet pipe and the resin cavity, or between the resin cavity and the water cup, and the flushing flow rate can be controlled by the water pump.

[0156] 409. When it is not necessary to rinse the cup, the controller controls the dishwasher to drain the water and terminate the rinsing process.

[0157] Through the above steps 405-409, when the resin of the dishwasher is regenerated and the resin chamber does not need to be rinsed again, it is determined whether the water cup needs to be rinsed according to the amount of high-concentration regenerated water remaining in the water cup. In the case where the water cup needs to be rinsed, the second rinse parameter for rinsing the water cup is determined according to the amount of high-concentration regenerated water remaining in the water cup. The second rinse parameter is a rinse water volume / rinse flow rate that matches the residual amount of high-concentration regenerated water in the water cup. The water cup is rinsed using the second rinse parameter to prevent insufficient rinsing and excessive rinsing, thereby improving the rinsing effect.

[0158] In order to more clearly explain the method for flushing the resin cavity of the dishwasher provided in the embodiment of the present application, the following will be combined with Figure 5 A method for flushing a resin cavity of a dishwasher provided in an embodiment of the present application is described.

[0159] See also Figure 5 , the controller controls the water intake of the dishwasher and obtains the initial water quality value S0 of the water intake of the dishwasher. The controller controls the addition of high-concentration regenerated water to the resin chamber of the dishwasher, so that the high-concentration regenerated water reacts with the resin in the resin chamber, that is, regenerates the resin. When the resin is regenerated, the controller obtains the first water quality value S1 in the resin chamber. The controller divides the first water quality value S1 by the initial water quality value S0 to obtain the first regeneration residual parameter n. The controller determines whether the first regeneration residual parameter n is greater than or equal to the first parameter threshold value n sv1 , when the first regeneration residual parameter n is greater than or equal to the first parameter threshold nsv1 In the case of , it indicates that the resin chamber needs to be flushed, and the controller determines whether the first regeneration residual parameter n is greater than the second parameter threshold value n sv2 When the first regeneration residual parameter n is less than or equal to the second parameter threshold value n sv2 In the case of , the controller determines the flushing water volume for flushing the resin chamber as the first water volume Q1. sv2 In the case of the second water volume Q2, the controller determines the flushing water volume for flushing the resin cavity as the second water volume Q2. After flushing the resin cavity, the controller flushes and obtains the first water quality value S1 in the resin cavity, and re-determines the first regeneration residual parameter n based on the re-obtained first water quality value S1 and the initial water quality value S0, and uses the first regeneration residual parameter n to determine whether the resin cavity needs to be flushed. If the resin cavity needs to be flushed, the flushing water volume is determined in the above manner.

[0160] When the first regeneration residual parameter n is less than the first parameter threshold n sv1 , indicating that the resin chamber does not need to be rinsed, the controller controls the dishwasher to drain, and after the drainage is completed, controls the dishwasher to fill with water and obtains the second water quality value S2 in the water cup. The controller divides the second water quality value S2 by the initial water quality value S0 to obtain the second regeneration residual parameter m. The controller determines whether the second regeneration residual parameter m is greater than the third parameter threshold m sv , the third parameter threshold m sv is less than the first parameter threshold n sv1 When the second regeneration residual parameter m is greater than the third parameter threshold m sv In the case of , it means that the cup needs to be rinsed, and the controller controls the dishwasher to feed water to rinse the cup. After rinsing the cup, the controller re-acquires the second water quality value S2 in the cup, and re-determines the second regeneration residual parameter m based on the re-acquired second water quality value S2 and the initial water quality value S0, and uses the second regeneration residual parameter m to determine whether the cup needs to be rinsed. When the second regeneration residual parameter m is less than or equal to the third parameter threshold m sv In the case of , it means that the cup does not need to be rinsed, and the controller controls the dishwasher to drain the water and terminate the rinsing process.

[0161] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0162] When the resin of the dishwasher is regenerated, it is determined whether the resin cavity needs to be rinsed according to the amount of high-concentration regenerated water remaining in the resin cavity. When the resin cavity needs to be rinsed, the first rinse parameter for rinsing the resin cavity is determined according to the amount of high-concentration regenerated water remaining in the resin cavity, and the first rinse parameter is a rinse water volume / rinse flow rate that matches the residual amount of high-concentration regenerated water in the resin cavity. The resin cavity is rinsed using the first rinse parameter to prevent insufficient rinsing and excessive rinsing, thereby improving the rinsing effect. In addition, when the resin of the dishwasher is regenerated and it is not necessary to rinse the resin cavity again, it is determined whether the water cup needs to be rinsed according to the amount of high-concentration regenerated water remaining in the water cup. When the water cup needs to be rinsed, the second rinse parameter for rinsing the water cup is determined according to the amount of high-concentration regenerated water remaining in the water cup, and the second rinse parameter is a rinse water volume / rinse flow rate that matches the residual amount of high-concentration regenerated water in the water cup. The water cup is rinsed using the second rinse parameter to prevent insufficient rinsing and excessive rinsing, thereby improving the rinsing effect.

[0163] Figure 6 Schematic diagram of the structure of a washing device for a resin chamber of a dishwasher provided in an embodiment of the present application, see Figure 6 The device includes: a flushing judgment module 601, a flushing parameter determination module 602 and a control module 603.

[0164] The flushing judgment module 601 is used to determine whether the resin cavity of the dishwasher needs to be flushed when the resin of the dishwasher has completed regeneration based on the first regeneration residual parameter of the resin cavity of the dishwasher. The first regeneration residual parameter is used to indicate the amount of high-concentration regeneration water remaining in the resin cavity.

[0165] The flushing parameter determination module 602 is used to determine a first flushing parameter for flushing the resin cavity based on the first regeneration residual parameter when flushing the resin cavity is required. The first flushing parameter includes a flushing water volume and / or a flushing flow rate.

[0166] The control module 603 is used to control the dishwasher to rinse the resin cavity based on the first rinsing parameter.

[0167] It should be noted that: the above-mentioned embodiment provides a washing device for the resin cavity of the dishwasher, and only uses the division of the above-mentioned functional modules as an example when washing the resin cavity of the dishwasher. In actual applications, the above-mentioned functions can be distributed to different functional modules as needed, that is, the internal structure of the dishwasher is divided into different functional modules to complete all or part of the functions described above. In addition, the washing device for the resin cavity of the dishwasher provided in the above-mentioned embodiment and the embodiment of the washing method for the resin cavity of the dishwasher belong to the same concept, and the specific implementation process is detailed in the method embodiment, which will not be repeated here.

[0168] When the resin of the dishwasher is completely regenerated, it is determined whether the resin cavity needs to be flushed according to the amount of high-concentration regenerated water remaining in the resin cavity. When the resin cavity needs to be flushed, a first flushing parameter for flushing the resin cavity is determined according to the amount of high-concentration regenerated water remaining in the resin cavity. The first flushing parameter is a flushing water volume / flushing flow rate that matches the residual amount of high-concentration regenerated water in the resin cavity. The resin cavity is flushed using the first flushing parameter to prevent insufficient flushing and excessive flushing, thereby improving the flushing effect.
