Obviously, the accompanying drawings described below are only some embodiments of this application.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] In this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function. It should be understood that there is no logical or temporal dependency between "first," "second," and "nth," nor is there any limitation on the quantity or execution order.

[0040] 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.

[0041] The main function of rinsing agents is to reduce the surface tension of water during the rinsing stage of a dishwasher, helping to remove detergent residue from dishes and making them shinier and cleaner.

[0042] Detergent is a core consumable in the dishwasher cleaning process, responsible for removing grease and food residue from dishes. Detergent typically comes in powder, tablet, and liquid form. Powder detergent is mostly in powder form and requires adjustment of the dosage based on the greasiness of the dishes and the water quality of the dishwasher; tablet detergent is pre-mixed in a specific ratio and can be added directly to the dishwasher for convenience; liquid detergent is a liquid form suitable for certain dishwasher models.

[0043] A water quality sensor is a sensor used to measure water quality. In the embodiments of this application, the water quality sensor includes an organic matter sensor or a conductivity sensor, etc. The organic matter sensor is used to measure the concentration of organic matter in water, and the conductivity sensor is used to measure the concentration of inorganic matter in water.

[0044] A dishwasher's washing cycle typically includes pre-wash, main wash, rinse, and dry. These correspond to the dishwasher's washing program sequence: pre-wash, main wash, rinse, and dry. The pre-wash is the first step in the washing process, designed to remove large food particles from the surface of the dishes. This step usually uses lower water pressure and a longer washing time to soften and dissolve the food particles, preparing them for the subsequent main wash cycle. The main wash is the core washing program of the dishwasher, using higher water pressure and temperature, and detergent is also added. The rotating arms inside the dishwasher release high-pressure water jets, spraying them onto the surface of the dishes to effectively remove grease, food residue, and dirt. The rinse cycle is designed to remove detergent and foam and other residues generated during the washing process. In this step, the dishwasher rinses away detergent and grease and impurities produced during the washing process, leaving the dishes clean and free of detergent residue. Drying is the final step in the washing process, using hot air or a heating device to evaporate the moisture from the surface of the dishes, ensuring they are dry and sterile. Dryed dishes effectively prevent bacterial growth and are easier to store later.

[0045] In related technologies, the main wash and rinse sequences of dishwashers are usually fixed, and ordinary water (tap water) is often used for both. However, since the number and type of dishes placed by users each time, as well as the type of food residue on the dishes, may vary, using a fixed type of water for the main wash or rinse often results in poor washing performance.

[0046] The technical solutions provided in this application can improve the above-mentioned problems, thereby improving the washing effect of the dishwasher.

[0047] Referring to Figure 1, which is a schematic diagram of a dishwasher according to an embodiment of this application, the 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 softens the water, reduces the calcium and magnesium ion content in the water, prevents scale formation, ensures the normal operation of the dishwasher, and extends its service life. The first connecting pipe 103 connects the resin chamber and the water cup 104, allowing water from the resin chamber 102 to enter the water cup 104 through the first connecting pipe 103. The water cup 104 is located at the bottom of the inner tub 107 of the dishwasher 100. The inner tub 107 is used to hold the dishes to be cleaned. The second connecting pipe 105 is used to connect the water cup 104 and the water pump 106. The water pump 106 can pump water from the water cup 104 into the inner tub 107 to clean or rinse the dishes inside the inner tub 107.

[0048] After introducing the structural schematic diagram of the dishwasher provided in the embodiments of this application, the implementation environment of the embodiments of this application will be described below. Referring to Figure 2, Figure 2 is a schematic diagram of the implementation environment of a dishwasher control method provided in the embodiments of this application. The implementation environment includes a dishwasher controller 201, a first water quality sensor 202, and a second water quality sensor 203. The controller 201 is electrically connected to the first water quality sensor 202 and the second water quality sensor 203, and the controller 201 can acquire the data collected by the first water quality sensor 202 and the second water quality sensor 203. The first water quality sensor 202 is used to measure a first water quality value of the water in the dishwasher 100. The first water quality value can reflect the amount of residual organic matter in the water in the dishwasher 100. In some embodiments, the first water quality sensor 202 is an organic matter sensor, such as a spectral sensor or a turbidity sensor. The second water quality sensor 203 is used to measure a second water quality value of the water in the dishwasher 100. The second water quality value can reflect the amount of residual inorganic matter in the water in the dishwasher 100. In some embodiments, the second water quality sensor 203 is an inorganic matter sensor, such as a conductivity sensor. In some embodiments, referring to FIG1, both the first water quality sensor 202 and the second water quality sensor 203 are installed inside the water cup 104 of the dishwasher 100. In this embodiment, the controller 201 can use the data collected by the first water quality sensor 202 and the second water quality sensor 203 to control the dishwasher 100 and improve the washing effect of the dishwasher 100. In some embodiments, the first water quality sensor 202 is an organic matter sensor, and the second water quality sensor 203 is a conductivity sensor.

[0049] After introducing the implementation environment of the embodiments of this application, the application scenarios of the embodiments of this application will be described below. The technical solution provided by the embodiments of this application can be applied to various dishwashers equipped with microbubble components. After adopting the technical solution provided by the embodiments of this application, when the dishwasher completes the water intake in the current washing sequence, the residual concentration of organic matter and inorganic matter in the water inside the dishwasher is used to indirectly represent the residual amount of organic and inorganic matter on the dishes inside the dishwasher. The residual concentration of organic matter and inorganic matter is used to determine the type of rinsing water. The dishwasher is controlled to perform the current washing sequence based on the type of rinsing water, thereby improving the washing effect.

[0050] After introducing the implementation environment and application scenarios of the embodiments of this application, the washing control method of the dishwasher provided by the embodiments of this application will be described below. Referring to Figure 3, taking the controller of the dishwasher as the execution subject as an example, the washing control method includes the following steps.

[0051] 301: When the dishwasher completes the water intake in the current sequence of the washing program, the controller obtains a first water quality value and a second water quality value of the water in the dishwasher. The first water quality value is used to indicate the amount of organic matter residue on the tableware, and the second water quality value is used to indicate the amount of inorganic matter residue on the tableware.

[0052] The washing program includes a pre-wash sequence, a main wash sequence, a rinse sequence, and a drying sequence. The current sequence refers to either the main wash sequence or the rinse sequence. The main wash sequence is the primary sequence for removing stains from the surface of the dishes. The rinse sequence, which occurs after the main wash sequence, mainly removes residual detergent and grease from the dishes, improving their cleanliness. During the main wash and rinse sequences, the water pump performs multiple cycles of rinsing. In each cycle, the water pump circulates water from the dishwasher's water cup into the inner drum, allowing it to contact the dishes and rinse them. The first and second water quality values ​​are different types of water quality values, which are obtained by different types of sensors within the dishwasher.

[0053] 302: The controller determines the flushing water type for the current time sequence based on the first water quality value and the second water quality value. The flushing water type includes microbubble water and ordinary water.

[0054] Microbubble water is particularly effective at rinsing organic matter, making it suitable for removing residual organic residue from tableware. While microbubble water and regular water (such as tap water) are generally equally effective at rinsing inorganic matter, producing microbubble water requires additional energy; therefore, regular water is sufficient for rinsing inorganic matter. The type of rinsing water used in the current sequence is determined by using a first and second water quality value, ensuring that the type of rinsing water used matches the residue on the tableware, thereby improving the washing effect.

[0055] 303: The controller controls the current timing of the dishwasher's washing program based on the type of rinsing water.

[0056] The type of rinsing water is matched with the residue on the tableware. Controlling the dishwasher to wash based on this type of rinsing water can effectively remove residual organic and / or inorganic matter from the tableware, thereby achieving a better washing effect.

[0057] The technical solution provided in this application, when the dishwasher completes its washing program and is currently filling with water, indirectly indicates the amount of organic and inorganic residues on the dishes inside the dishwasher based on the residual concentrations of organic and inorganic matter in the water. The type of rinsing water for the current washing cycle is determined using the residual concentrations of organic and inorganic matter. By controlling the dishwasher's execution of the current washing program based on the type of rinsing water, the washing effect is improved.

[0058] Steps 301 to 303 above are a brief introduction to the washing control method of the dishwasher provided in the embodiments of this application. The technical solution provided in the embodiments of this application will be explained more clearly below with some examples. Referring to Figure 4, taking the controller of the dishwasher as the execution subject as an example, the washing control method includes the following steps.

[0059] 401: When the dishwasher completes the water intake in the current sequence of the washing program, the controller obtains a first water quality value and a second water quality value of the water in the dishwasher. The first water quality value is used to indicate the amount of organic matter residue on the tableware, and the second water quality value is used to indicate the amount of inorganic matter residue on the tableware.

[0060] The washing program includes a pre-wash sequence, a main wash sequence, a rinsing sequence, and a drying sequence. The current sequence refers to either the main wash sequence or the rinsing sequence. Correspondingly, the water intake at the completion of the current sequence refers to the water intake at the completion of either the main wash sequence or the rinsing sequence. The main wash sequence is the primary sequence for removing stains from the surface of the tableware. The rinsing sequence is performed after the main wash sequence and is mainly to remove residual detergent and grease from the tableware, improving its cleanliness. It should be noted that there may be multiple rinsing sequences. This rinsing sequence refers to one of several rinsing sequences. For example, if there are two rinsing sequences, designated as the first rinsing sequence and the second rinsing sequence, then the aforementioned rinsing sequence refers to either the first rinsing sequence or the second rinsing sequence. During the main wash and rinse cycles, the water pump performs multiple rounds of rinsing. In each cycle, the pump circulates water from the dishwasher's water cup into the inner drum, ensuring contact with the dishes and rinsing them. The water in the dishwasher is the water that has been filled and sprayed during the current cycle, ensuring sufficient contact between the water and the dishes. The first water quality value indicates the amount of organic residue on the dishes, and the second water quality value indicates the amount of inorganic residue.

[0061] In one possible implementation, when the dishwasher completes the water intake for the current time in the washing program, the controller obtains the first water quality value through an organic matter sensor inside the dishwasher, and the controller obtains the second water quality value through a conductivity sensor inside the dishwasher.

[0062] The organic matter sensor can measure the concentration of organic matter in water. In some embodiments, the organic matter sensor is a spectral sensor. The principle of a spectral sensor is that when light passes through water, different wavelengths of light are absorbed by different substances in the water, forming a specific absorption spectrum. By analyzing the absorption spectrum, the type and concentration of organic matter in the water can be identified. In some embodiments, the spectral sensor includes a light source, a light receiver, and a data processing unit. The light source is used to emit light, the light receiver is used to receive light, and the data processing unit is used to determine a first water quality value based on the intensity difference between the emitted light intensity and the received light intensity. The algorithm used by the data processing unit to determine turbidity based on the intensity difference between light intensities is set by a technician according to the actual situation, and this application embodiment does not limit it. Of course, the above-described structure of the spectral sensor is merely an example. In other possible embodiments, the spectral sensor may include more or fewer components, and this application embodiment does not limit it.

[0063] The working principle of a conductivity sensor mainly relies on the relationship between ions present in a liquid and electric current. When current flows through a liquid, ions interfere with the flow of current, thereby changing the conductivity value. By measuring this change in conductivity, the sensor can determine the ion concentration in the liquid, thus achieving the measurement of the liquid's conductivity. Inorganic substances in water usually exist in the form of ions. The conductivity sensor can measure the conductivity of water, and the conductivity of water indicates the amount of ions in the water, thereby enabling the measurement of the concentration of inorganic substances in the water. In some embodiments, the organic matter sensor and the conductivity sensor are placed inside the water cup of a dishwasher. Since water falls into the water cup during the inlet water and the water pump's circulating rinsing, this arrangement allows for the measurement of the water quality value inside the dishwasher.

[0064] In this implementation, the first and second water quality values ​​of the water inside the dishwasher can be directly obtained using an organic matter sensor and a conductivity sensor, resulting in high efficiency in obtaining the first and second water quality values.

[0065] For example, when the dishwasher completes its washing cycle and water is being introduced at the current time, the controller acquires multiple initial water quality values ​​using an organic matter sensor within the dishwasher. Different initial water quality values ​​correspond to different sampling times. The controller determines the average of these multiple initial water quality values ​​as the first water quality value. The controller also acquires multiple second initial water quality values ​​using a conductivity sensor within the dishwasher. Different second initial water quality values ​​correspond to different sampling times. The controller determines the average of these multiple second initial water quality values ​​as the second water quality value.

[0066] In addition, to explain step 401 more clearly, the water intake situation during the current sequence of the dishwasher's washing program will be explained below.

[0067] In some embodiments, when the dishwasher reaches the current time sequence in the washing program, the controller controls the dishwasher to fill with water. After the water filling is complete, the controller controls the water pump to pump the water in the dishwasher into the inner tub of the dishwasher, that is, to spray it, so that the water in the dishwasher can fully contact the dishes in the dishwasher.

[0068] A certain spraying time allows the water in the dishwasher to fully contact the dishes inside. The spraying time is set by technicians according to the actual situation, such as 2 minutes or 4 minutes. This application embodiment does not limit this.

[0069] 402: The controller determines whether the current timing sequence needs to be executed based on the first water quality value and the second water quality value.

[0070] Since the first and second water quality values ​​represent the residual amounts of organic and inorganic matter, and the main wash and rinsing sequences are designed to remove these residues, these values ​​can be used to determine whether the current sequence needs to be executed. Generally, if the residual amount of organic and / or inorganic matter is high, the current sequence needs to be executed. Conversely, if the residual amount is low, the current sequence does not need to be executed.

[0071] In one possible implementation, if the first water quality value is greater than a first water quality threshold, the controller determines that the current timing sequence needs to be executed. If the first water quality value is less than or equal to the first water quality threshold, the controller determines whether the second water quality value is greater than a second water quality threshold. If the second water quality value is greater than the second water quality threshold, the controller determines that the current timing sequence needs to be executed. If the second water quality value is less than or equal to the second water quality threshold, the controller determines that the current timing sequence does not need to be executed.

[0072] In this process, a first water quality value greater than a first water quality threshold indicates a higher amount of residual organic matter, thus requiring the current time sequence to remove the residual organic matter. Similarly, a second water quality value greater than a second water quality threshold indicates a higher amount of residual inorganic matter, requiring the current time sequence to remove the residual inorganic matter. Conversely, a first water quality value less than or equal to the first water quality threshold and a second water quality value less than or equal to the second water quality threshold indicate lower amounts of both organic and inorganic matter, thus eliminating the need to execute the current time sequence. It should be noted that the dishes in the dishwasher typically require cleaning during the main wash cycle. If the result of the above judgment during the main wash cycle indicates that the main wash cycle is not required, it means that the water in the dishwasher may not have fully contacted the dishes. In this case, the controller can control the water pump to spray again, and then execute the above judgment after spraying. Alternatively, the above judgment on whether to specify the current time sequence can be skipped during the main wash cycle, and the subsequent step of determining the type of rinsing water can be executed directly. This application embodiment does not limit this approach.

[0073] In this implementation, the first water quality value and the second water quality value are used to determine whether the current sequence needs to be executed, and the accuracy of the sequence execution determination is relatively high.

[0074] To provide a clearer explanation of the above embodiments, the method for determining the first water quality threshold and the second water quality threshold in the above embodiments will be described below.

[0075] First, the method for determining the first water quality threshold will be explained.

[0076] In one possible implementation, the washing program includes a main wash sequence and a rinsing sequence, with the current sequence being the rinsing sequence. The controller acquires the initial water intake volume of the dishwasher and an initial first water quality value, which represents the organic matter content in the initial water intake. Based on the initial first water quality value, the initial water intake volume, and the current water volume in the dishwasher, the controller determines a first water quality threshold.

[0077] The initial water intake volume refers to either the water volume entering during the main wash cycle or the water volume entering during the rinsing cycle. Correspondingly, the initial first water quality value reflects the water quality conditions in the dishwasher's location and can serve as a benchmark for determining the first water quality threshold. That is, the organic matter content reflected by the first water quality threshold cannot be less than the organic matter content reflected by the initial first water quality value; otherwise, determining the relationship between the first water quality value and the first water quality threshold would be meaningless. Since the initial first water quality value directly reflects the concentration of organic matter, and the initial water intake volume and current water volume of the dishwasher may not be the same, the initial water intake volume and current water volume are used to eliminate the influence of different water volumes on the concentration in order to improve the accuracy of the first water quality threshold.

[0078] In the above implementation, the initial first water quality value, the initial water intake, and the current water volume are used to determine the first water quality value threshold, so that the determined first water quality value threshold is more in line with the actual situation inside the dishwasher and the water quality of the area where the dishwasher is located, and the accuracy of the first water quality value threshold is better.

[0079] For example, the controller determines the initial water intake volume of the dishwasher during the main wash cycle as the initial water intake volume. The controller determines the water quality value of the initial water intake volume of the dishwasher during the main wash cycle as the initial first water quality value. The controller multiplies the initial first water quality value by the initial water intake volume and divides it by the current water volume in the dishwasher to obtain the first water quality threshold.

[0080] In the above implementation, the first water quality threshold is equivalent to the conversion of the initial first water quality value under different water volumes. If the first water quality value is greater than the first water quality threshold, it means that the content of residual organic matter in the water is higher than that in the initial influent. Therefore, it is necessary to execute the current sequence to reduce the amount of residual organic matter.

[0081] Based on the examples above, there are also the following methods for determining the first water quality threshold.

[0082] For example, when the dishwasher begins its main wash cycle and initially fills with water, the controller obtains an initial first water quality value using an organic matter sensor inside the dishwasher. The controller multiplies this initial first water quality value by the initial water intake volume and then divides it by the current water volume in the dishwasher to obtain a first reference water quality threshold. The controller then multiplies this first reference water quality threshold by a first correction factor, which is determined based on the error in the first water quality value and the allowable residual amount of organic matter.

[0083] The error includes measurement error and correction error, reflecting the error present in the organic matter sensor when measuring the first water quality value. The allowable residual amount can be set by technicians according to the actual situation, and this application embodiment does not limit this. The first correction coefficient is used to introduce the influence of error and allowable residual amount in the process of determining the first water quality value threshold, thereby improving the accuracy of the first water quality value threshold.

[0084] In this implementation, instead of directly equating the initial first water quality value with the first water quality threshold, a first correction coefficient based on error and allowable residue is introduced, making the determined first water quality threshold more compatible with the actual situation and more usable.

[0085] To provide a clearer explanation of the above implementation method, the method for determining the multiplication of the first correction coefficient will be described below.

[0086] In some embodiments, the controller adds the measurement error and correction error of the first water quality value to the target value respectively to obtain a first error coefficient and a second error coefficient. The controller multiplies the first error coefficient, the second error coefficient, and the reciprocal of the allowable residue to obtain the first correction coefficient. The target value is 1.

[0087] The method for determining the second water quality threshold is explained below.

[0088] In one possible implementation, the washing program includes a main wash sequence and a rinsing sequence, with the current sequence being the rinsing sequence. The controller acquires the initial water intake volume of the dishwasher and an initial second water quality value for the initial water intake, the initial second water quality value representing the content of inorganic substances in the initial water intake. Based on the initial second water quality value, the initial water intake volume, and the current water volume in the dishwasher, the controller determines a second water quality threshold.

[0089] The initial second water quality value reflects the water quality in the area where the dishwasher is located and can serve as a benchmark for determining the second water quality threshold. That is, the inorganic matter content reflected by the second water quality threshold cannot be less than the inorganic matter content reflected by the initial second water quality value; otherwise, determining the relationship between the second water quality value and the second water quality threshold would be meaningless. Since the initial second water quality value directly reflects the concentration of inorganic matter, and the initial water intake and current water volume of the dishwasher may not be the same, the initial water intake and current water volume are used to eliminate the influence of different water volumes on the concentration in order to improve the accuracy of the second water quality threshold.

[0090] In the above implementation, the initial second water quality value, the initial water intake, and the current water volume are used to determine the second water quality value threshold, so that the determined second water quality value threshold is more in line with the actual situation inside the dishwasher and the water quality of the area where the dishwasher is located, and the accuracy of the second water quality value threshold is better.

[0091] For example, when the dishwasher is filling with water for the initial main wash cycle, the controller obtains the initial second water quality value through a conductivity sensor inside the dishwasher. The controller multiplies this initial second water quality value by the initial water intake and then divides it by the current water volume in the dishwasher to obtain the second water quality threshold.

[0092] In the above implementation, the second water quality threshold is equivalent to the conversion of the initial second water quality value under different water volumes. If the second water quality value is greater than the second water quality threshold, it means that the content of residual inorganic matter in the water is greater than that in the initial influent. Therefore, it is necessary to execute the current sequence to reduce the amount of residual inorganic matter.

[0093] Based on the examples above, there are also the following methods for determining the second water quality threshold.

[0094] For example, when the dishwasher begins its main wash cycle and initially fills with water, the controller obtains the initial second water quality value using a conductivity sensor within the dishwasher. The controller multiplies this initial second water quality value by the initial water intake volume and then divides it by the current water volume in the dishwasher to obtain a first reference water quality threshold. The controller then multiplies this first reference water quality threshold by a second correction factor, which is determined based on the error in the second water quality value and the allowable residual amount of inorganic matter.

[0095] The error includes measurement error and correction error, reflecting the error present in the conductivity sensor when measuring the second water quality value. The allowable residual amount is set by technicians according to the actual situation, and this application embodiment does not limit this. The second correction coefficient is used to introduce the influence of error and allowable residual amount in the process of determining the second water quality value threshold, thereby improving the accuracy of the second water quality value threshold.

[0096] In this implementation, instead of directly equating the initial second water quality value with the second water quality threshold, a second correction coefficient based on error and allowable residue is introduced, making the determined second water quality threshold more compatible with the actual situation and more usable.

[0097] To provide a clearer explanation of the above implementation method, the method for determining the multiplication of the second correction coefficient will be described below.

[0098] In some embodiments, the controller adds the measurement error and correction error of the second water quality value to the target value respectively to obtain a first error coefficient and a second error coefficient. The controller multiplies the first error coefficient, the second error coefficient, and the reciprocal of the allowable residue to obtain the second correction coefficient. The target value is 1.

[0099] Another implementation of step 402 described above will be described below.

[0100] In one possible implementation, the controller determines the residual organic matter concentration corresponding to the first water quality value. If the residual organic matter concentration is greater than an organic matter concentration threshold, the controller determines that the current timing sequence needs to be executed. If the residual organic matter concentration is less than or equal to the organic matter concentration threshold, the controller determines the residual inorganic matter concentration corresponding to the second water quality value. If the residual inorganic matter concentration is greater than an inorganic matter concentration threshold, the controller determines that the current timing sequence needs to be executed. If the residual inorganic matter concentration is less than or equal to the inorganic matter concentration threshold, the controller determines that the current timing sequence does not need to be executed.

[0101] In this implementation, the residual organic matter concentration corresponding to the first water quality value and the residual inorganic matter concentration corresponding to the second water quality value are used to determine whether the current sequence needs to be executed, and the execution determination of the current sequence is highly accurate.

[0102] The method for determining the residual concentrations of organic and inorganic substances in the above embodiments will be explained below.

[0103] First, the method for determining the concentration of residual organic matter will be explained.

[0104] In some embodiments, the controller substitutes the first water quality value into the first relational data to obtain the organic residue concentration corresponding to the first water quality value. The first relational data is used to represent the correspondence between the first water quality value and the organic residue concentration.

[0105] The first relational data is obtained by linearly fitting the first water quality value of multiple samples and the actual organic residue concentration corresponding to the first water quality value of each sample. Therefore, substituting the first water quality value into the first relational data can yield the corresponding organic residue concentration.

[0106] The method for determining the residual concentration of inorganic substances is explained below.

[0107] In some embodiments, the controller substitutes the second water quality value into the second relational data to obtain the organic residue concentration corresponding to the second water quality value. The second relational data is used to represent the correspondence between the second water quality value and the inorganic residue concentration.

[0108] The second relationship data is obtained by linearly fitting the second water quality values ​​of multiple samples and the actual inorganic residue concentrations corresponding to the second water quality values ​​of each sample. Therefore, substituting the second water quality value into the second relationship data can yield the corresponding inorganic residue concentration.

[0109] To provide a clearer explanation of the above embodiments, the methods for determining the organic residue concentration threshold and the inorganic residue concentration threshold in the above embodiments will be described below.

[0110] First, we will explain the method for determining the threshold for residual organic matter concentration.

[0111] In one possible implementation, the controller acquires the initial water intake volume of the dishwasher and an initial first water quality value, which represents the organic matter content in the initial water intake. The controller determines the initial residual organic matter concentration corresponding to the initial first water quality value. Based on the initial residual organic matter concentration, the initial water intake volume, and the current water volume in the dishwasher, the controller determines an organic matter residual concentration threshold.

[0112] The initial residual organic matter concentration reflects the water quality in the area where the dishwasher is located and can serve as a benchmark for determining the residual organic matter concentration threshold. In other words, the residual organic matter concentration threshold must reflect an organic matter content no less than the initial residual organic matter concentration; otherwise, determining the relationship between the residual organic matter concentration corresponding to the first water quality value and the residual organic matter concentration threshold becomes meaningless. Since the initial residual organic matter concentration directly reflects the concentration of organic matter, and the initial water intake and current water volume of the dishwasher may not be the same, the initial water intake and current water volume are used to eliminate the influence of different water volumes on the concentration in order to improve the accuracy of the residual organic matter concentration threshold.

[0113] In the above implementation method, the organic residue concentration threshold is determined by using the initial organic residue concentration corresponding to the initial first water quality value, the initial water intake, and the current water volume. This makes the determined organic residue concentration threshold more consistent with the actual situation inside the dishwasher and the water quality of the area where the dishwasher is located, and the accuracy of the organic residue concentration threshold is better.

[0114] For example, when the dishwasher begins its main wash cycle and initially fills with water, the controller obtains the initial water quality value using an organic matter sensor inside the dishwasher. The controller then substitutes this initial water quality value into a first relational data set to obtain the initial residual organic matter concentration corresponding to the initial water quality value. Finally, the controller multiplies this initial residual organic matter concentration by the initial water intake and divides it by the current water volume inside the dishwasher to obtain the residual organic matter concentration threshold.

[0115] In the above implementation, the organic residue concentration threshold is equivalent to the conversion of the initial organic residue concentration under different water volumes. If the organic residue concentration is greater than the organic residue concentration threshold, it means that the content of residual organic matter in the water is higher than that in the initial influent. Therefore, it is necessary to execute the current sequence to reduce the amount of residual organic matter.

[0116] Based on the examples above, there are also the following methods for determining the threshold for residual organic matter concentration.

[0117] For example, when the dishwasher is initially filling with water after completing the main wash cycle, the controller obtains the initial first water quality value through the organic matter sensor inside the dishwasher. The controller substitutes this initial first water quality value into first relational data to obtain the initial residual organic matter concentration corresponding to the initial first water quality value. The controller multiplies this initial residual organic matter concentration by the initial water intake volume and divides it by the current water volume in the dishwasher to obtain a first reference residual organic matter concentration threshold. The controller multiplies this first reference residual organic matter concentration threshold by a first correction coefficient to obtain the final residual organic matter concentration threshold. This first correction coefficient is determined based on the error of the first water quality value and the allowable residual amount of organic matter.

[0118] The error includes measurement error and correction error, reflecting the error present in the organic matter sensor when measuring the first water quality value. The allowable residue level is set by technicians according to the actual situation, and this application embodiment does not limit this. The first correction coefficient is used to introduce the influence of error and allowable residue level in the process of determining the organic matter residue concentration threshold, thereby improving the accuracy of the organic matter residue concentration threshold.

[0119] In this implementation, instead of directly equating the initial organic residue concentration corresponding to the initial first water quality value to the organic residue concentration threshold, a first correction coefficient based on error and allowable residue amount is introduced, making the determined organic residue concentration threshold more compatible with the actual situation and more usable.

[0120] The method for determining the residual concentration threshold of inorganic substances is explained below.

[0121] In one possible implementation, the controller acquires the initial water intake volume of the dishwasher and an initial second water quality value representing the inorganic content in the initial water intake. The controller determines the initial residual inorganic concentration corresponding to the initial second water quality value. Based on the initial residual inorganic concentration, the initial water intake volume, and the current water volume in the dishwasher, the controller determines an inorganic residual concentration threshold.

[0122] The initial inorganic residue concentration reflects the water quality of the area where the dishwasher is located and can serve as a benchmark for determining the inorganic residue concentration threshold. In other words, the inorganic residue concentration threshold must reflect an inorganic residue content that is not less than the initial inorganic residue concentration; otherwise, determining the relationship between the inorganic residue concentration corresponding to the second water quality value and the inorganic residue concentration threshold would be meaningless. Since the initial inorganic residue concentration directly reflects the concentration of inorganic substances, and the initial water intake and current water volume of the dishwasher may not be the same, the initial water intake and current water volume are used to eliminate the influence of different water volumes on the concentration in order to improve the accuracy of the inorganic residue concentration threshold.

[0123] In the above implementation method, the inorganic residue concentration threshold is determined by using the initial inorganic residue concentration corresponding to the initial second water quality value, the initial water inflow, and the current water flow. This makes the determined inorganic residue concentration threshold more consistent with the actual situation inside the dishwasher and the water quality of the area where the dishwasher is located, and the accuracy of the inorganic residue concentration threshold is better.

[0124] For example, when the dishwasher begins its main wash cycle and initially fills with water, the controller obtains the initial second water quality value using an inorganic sensor inside the dishwasher. The controller then substitutes this initial second water quality value into the second relational data to obtain the initial inorganic residue concentration corresponding to the initial second water quality value. Finally, the controller multiplies this initial inorganic residue concentration by the initial water intake volume and divides it by the current water volume inside the dishwasher to obtain the inorganic residue concentration threshold.

[0125] In the above embodiments, the inorganic residue concentration threshold is equivalent to the conversion of the initial inorganic residue concentration under different water volumes. If the inorganic residue concentration is greater than the inorganic residue concentration threshold, it means that the content of inorganic residue in the water is greater than that in the initial influent. Therefore, it is necessary to execute the current sequence to reduce the amount of inorganic residue.

[0126] Based on the examples above, there are also the following methods for determining the residual concentration threshold of inorganic substances.

[0127] For example, when the dishwasher is initially filled with water after completing the main wash cycle, the controller obtains the initial second water quality value through the inorganic matter sensor inside the dishwasher. The controller substitutes this initial second water quality value into the second relational data to obtain the initial inorganic matter residual concentration corresponding to the initial second water quality value. The controller multiplies this initial inorganic matter residual concentration by the initial water intake volume and divides it by the current water volume in the dishwasher to obtain a second reference inorganic matter residual concentration threshold. The controller multiplies this second reference inorganic matter residual concentration threshold by a second correction coefficient to obtain the inorganic matter residual concentration threshold, where the second correction coefficient is determined based on the error of the second water quality value and the allowable residual amount of inorganic matter.

[0128] The error includes measurement error and correction error, reflecting the error present in the inorganic sensor when measuring the second water quality value. The allowable residue level is set by technicians according to the actual situation, and this application embodiment does not limit this. The second correction coefficient is used to introduce the influence of error and allowable residue level in the process of determining the inorganic residue concentration threshold, thereby improving the accuracy of the inorganic residue concentration threshold.

[0129] In this implementation, instead of directly equating the initial inorganic residue concentration corresponding to the initial second water quality value to the inorganic residue concentration threshold, a second correction coefficient based on error and allowable residue is introduced, making the determined inorganic residue concentration threshold more compatible with the actual situation and more usable.

[0130] It should be noted that after step 403, the controller may execute steps 403 and 404 below, or execute step 405 below, depending on the actual situation. This application embodiment does not limit this.

[0131] 403: When the current sequence needs to be executed, the controller determines the flushing water type for the current sequence based on the first water quality value and the second water quality value. The flushing water type includes microbubble water and ordinary water.

[0132] The requirement to execute the current time sequence indicates a significant amount of residual organic and / or inorganic matter on the tableware. Microbubble water is effective at rinsing organic matter, therefore it can be used to remove residual organic matter from tableware. Microbubble water and ordinary water (such as tap water) have essentially the same rinsing effect on inorganic matter; however, producing microbubble water requires additional energy, so ordinary water is sufficient for rinsing inorganic matter. The type of rinsing water is determined using a first and second water quality value, ensuring that the type of rinsing water used in the current time sequence matches the amount of residue on the tableware, thereby improving the washing effect.

[0133] In one possible implementation, when the current timing needs to be executed and the first water quality value is greater than a first water quality threshold, the controller determines the flushing water type as microbubble water. When the first water quality value is less than or equal to the first water quality threshold and the second water quality value is greater than the second water quality threshold, the controller determines the flushing water type as ordinary water.

[0134] Microbubble water contains a large number of microbubbles. When these microbubbles burst in water, they create high-pressure shock waves. These shock waves have a strong cleaning ability and can effectively remove organic matter from the surface of tableware. Because microbubble water is effective at rinsing organic matter, when there is a high amount of organic matter residue, the amount of inorganic matter residue is not considered, and the rinsing water type is directly determined to be microbubble water. Microbubble water can be used to rinse both organic and inorganic matter. When there is a low amount of organic matter residue but a high amount of inorganic matter residue, the rinsing water type is determined to be ordinary water, and there is no need to consume energy to produce microbubble water.

[0135] In this implementation, the type of rinsing water is determined by the amount of residual organic and inorganic matter, so that the water used in the current sequence is more closely matched with the actual residue of the dishes in the dishwasher, thereby improving the rinsing effect of the current sequence.

[0136] Another implementation of step 403 described above will be described below.

[0137] In one possible implementation, when the current timing needs to be executed and the organic residue concentration corresponding to the first water quality value is greater than the organic residue concentration threshold, the controller determines the flushing water type as microbubble water. When the organic residue concentration corresponding to the first water quality value is less than or equal to the organic residue concentration threshold and the inorganic residue concentration corresponding to the second water quality value is greater than the inorganic residue concentration threshold, the controller determines the flushing water type as ordinary water.

[0138] The method for determining the organic / inorganic residual concentration corresponding to the water quality value belongs to the same inventive concept as described in the second embodiment of step 402 above. The implementation process is described in the relevant description in step 402 above, and will not be repeated here.

[0139] 404: The controller controls the current timing of the dishwasher's washing program based on the type of rinsing water.

[0140] The type of rinsing water is matched with the residue on the dishes. Controlling the dishwasher to execute the current sequence based on the type of rinsing water can better remove residual organic and / or inorganic matter on the dishes, thereby achieving a better washing effect.

[0141] In one possible implementation, if the rinsing water type is microbubble water, the controller controls the dishwasher to receive microbubble water from the microbubble assembly, which is used to generate microbubble water. Once the microbubble water intake is complete, the controller controls the dishwasher's water pump to operate to execute the current timing sequence.

[0142] In this embodiment, the microbubble water is generated by a dishwasher's microbubble assembly. Referring to Figure 5, the microbubble assembly 50 includes a dissolved air chamber 51, a bypass component 52, a connecting pipe 524, a bubbler 53, a liquid inlet valve 54, and a vent valve 55. Gas and liquid can mix within the dissolved air chamber 51, and then the bubbler 53 generates bubbles to form microbubble water. In some embodiments, the dissolved air chamber 51 has a vent, a liquid inlet, and a liquid outlet. Gas can enter the dissolved air chamber 51 through the vent, and liquid can enter through the liquid inlet. The gas and liquid entering the dissolved air chamber 51 can mix, thereby incorporating a certain amount of gas into the liquid, completing the dissolved air process. The bubbler 53 is connected to the liquid outlet. In other words, the gas-liquid mixture in the dissolved air chamber 51 enters the bubbler 53 through the liquid outlet. The bubbler 53 causes the gas in the gas-liquid mixture to be dispersed to form bubbles, thereby forming a large number of tiny bubbles in the liquid, resulting in microbubble water. In some embodiments, referring to FIG6, the microbubble assembly 50 is installed on the side of the dishwasher, the arrow pointing to the microbubble assembly 50 indicates water inlet, and the arrow pointing from the microbubble assembly 50 to the outside indicates water outlet entering the inner tank of the dishwasher.

[0143] In this implementation, when microbubble water is required, the dishwasher is controlled to draw water from the microbubble assembly. After the water intake is complete, the water pump is controlled to run to execute the current sequence, thereby achieving the purpose of using microbubble water to execute the current sequence.

[0144] For example, when the rinsing water type is microbubble water, the controller determines the first inlet volume of microbubble water based on the first water quality value and the initial first water quality value of the dishwasher water. The controller then controls the dishwasher to introduce microbubble water from the microbubble assembly according to the first inlet volume.

[0145] The first water quality value is used to represent the current organic matter concentration in the water inside the dishwasher. The initial first water quality value is the organic matter concentration in the water entering the dishwasher, which can be regarded as a benchmark for organic matter concentration. The first water quality value and the initial first water quality value are used to determine the first water intake, so that the first water intake during the current sequence matches the residual amount of organic matter in the dishwasher, thereby improving the rinsing effect of the current sequence.

[0146] The method for determining the first influent volume is explained below.

[0147] In one possible implementation, the controller determines a first water quality value difference between the first water quality value and the initial first water quality value. Based on this first water quality value difference, the controller determines a first influent flow rate, which is positively correlated with the first water quality value difference.

[0148] Compared to the initial water quality value, this difference in initial water quality value more accurately reflects the amount of organic residue on the dishes inside the dishwasher because it eliminates the influence of the organic content in the initial incoming water. Accordingly, the larger the difference in initial water quality value, the more organic residue on the dishes inside the dishwasher; the smaller the difference, the less organic residue. The initial water intake volume is positively correlated with this difference in initial water quality value, meaning that the larger the difference, the larger the initial water intake volume; and the smaller the difference, the smaller the initial water intake volume.

[0149] In this implementation, the first water intake is determined by the difference in the first water quality value. This first water intake is adapted to the amount of organic residue on the tableware, which can improve the rinsing effect on organic matter.

[0150] For example, the controller subtracts the first water quality value from the initial first water quality value to obtain the first water quality value difference. The controller then substitutes this first water quality value difference into third relational data to obtain the first influent volume. This third relational data represents the correspondence between the first water quality value difference and the first influent volume. Alternatively, the controller uses the first water quality value difference to query a first relational table to obtain the first influent volume. This first relational table stores multiple first water quality value differences and the corresponding first influent volumes for each first water quality value difference.

[0151] The third relationship data and the first relationship table are set by technicians according to the actual situation, and this application embodiment does not limit them.

[0152] In addition, if the current sequence is a rinsing sequence, step 404 above is the controller controlling the dishwasher to execute the rinsing sequence in the washing program based on the type of rinsing water; or, if the current sequence is a main washing sequence, the controller controls the dishwasher to execute the main washing sequence in the washing program based on the type of rinsing water.

[0153] Another implementation of step 404 described above will be described below.

[0154] In one possible implementation, if the rinsing water type is ordinary water, the controller controls the dishwasher to accept ordinary water from the inlet pipe. Once the ordinary water supply is complete, the controller controls the dishwasher's water pump to operate to execute the current timing sequence.

[0155] In this implementation, when ordinary water is required, the dishwasher is controlled to directly draw water from the dishwasher's water inlet pipe. After the water intake is complete, the water pump is controlled to run to execute the current sequence, thus achieving the purpose of using ordinary water to execute the current sequence.

[0156] For example, when the rinsing water type is ordinary water, the controller determines the second inlet volume of ordinary water based on the second water quality value and the initial second water quality value of the dishwasher water. The controller then controls the dishwasher to receive ordinary water from the inlet pipe according to this second inlet volume.

[0157] The second water quality value is used to represent the current inorganic concentration of the water in the dishwasher. The initial second water quality value is the inorganic concentration of the water entering the dishwasher, which can be regarded as a benchmark for the inorganic concentration. The second water intake is determined by using the second water quality value and the initial second water quality value, so that the second water intake in the current sequence matches the residual amount of inorganic matter in the dishwasher, thereby improving the rinsing effect in the current sequence.

[0158] The method for determining the second water inlet volume is explained below.

[0159] In one possible implementation, the controller determines a second water quality value difference between the second water quality value and the initial second water quality value. Based on this second water quality value difference, the controller determines a second influent flow rate, which is positively correlated with the second water quality value difference.

[0160] Compared to the second water quality value, this difference in second water quality values ​​more accurately reflects the amount of inorganic residue on the dishes inside the dishwasher because it eliminates the influence of the inorganic content in the initial inlet water. Accordingly, the larger the difference in second water quality values, the more inorganic residue remains on the dishes inside the dishwasher; the smaller the difference, the less inorganic residue remains. The second inlet water volume is positively correlated with this difference in second water quality values, meaning that the larger the difference, the larger the second inlet water volume; and the smaller the difference, the smaller the second inlet water volume.

[0161] In this implementation, the second water intake is determined by the difference in the second water quality value. This second water intake is adapted to the amount of inorganic residue on the tableware, which can improve the rinsing effect on inorganic residue.

[0162] For example, the controller subtracts the initial second water quality value from the second water quality value to obtain the difference in the second water quality value. The controller then substitutes this difference in the second water quality value into a fourth relational data set to obtain the second influent volume. This fourth relational data set represents the correspondence between the second water quality value difference and the second influent volume. Alternatively, the controller uses the second water quality value difference to query a second relational table to obtain the second influent volume. This second relational table stores multiple second water quality value differences and the corresponding second influent volumes for each second water quality value difference.

[0163] The fourth relationship data and the second relationship table are set by technicians according to the actual situation, and this application embodiment does not limit them.

[0164] Optionally, after step 404, the controller may also perform the following steps.

[0165] In one possible implementation, upon completion of the current sequence, the controller reacquires the first and second water quality values ​​of the water inside the dishwasher. Based on the reacquired first and second water quality values, the controller determines whether the dishwasher should execute the next sequence, which is the rinsing sequence.

[0166] Regardless of whether the current sequence is the main wash sequence or the rinsing sequence, the next sequence will be the rinsing sequence.

[0167] In other words, once the current sequence has been completed, the first and second water quality values ​​are re-acquired to determine whether a rinsing sequence is still needed, thus preventing the current sequence from failing to achieve the required rinsing effect on the dishes inside the dishwasher.

[0168] For example, after the current sequence of events has completed, the controller re-acquires the first and second water quality values ​​of the water inside the dishwasher. If the re-acquired first water quality value is greater than a first water quality threshold, the controller determines that the next sequence of events needs to be executed. If the re-acquired first water quality value is less than or equal to the first water quality threshold, the controller determines whether the re-acquired second water quality value is greater than the second water quality threshold. If the re-acquired second water quality value is greater than the second water quality threshold, the controller determines that the next sequence of events needs to be executed. If the re-acquired second water quality value is less than or equal to the second water quality threshold, the controller determines that the next sequence of events does not need to be executed.

[0169] In some embodiments, when the current sequence of events is executed when the first water quality value is greater than the first water quality threshold, determining whether to execute the next sequence requires first determining the relationship between the newly acquired first water quality value and the first water quality threshold, and then determining the relationship between the newly acquired second water quality value and the second water quality threshold, as described in the example above, to determine whether to execute the next sequence. When the current sequence of events is executed when the second water quality value is greater than the second water quality threshold, determining whether to execute the next sequence requires no further determination of the relationship between the newly acquired first water quality value and the first water quality threshold; the determination can be made directly based on the relationship between the newly acquired second water quality value and the second water quality threshold.

[0170] In addition, based on the above implementation, when it is determined that the dishwasher needs to execute the next sequence, the controller can also execute the following steps.

[0171] In one possible implementation, the controller determines the rinsing water type for the next cycle based on a first and a second reacquired water quality value. The controller then controls the dishwasher to execute the next cycle in the washing program based on this rinsing water type.

[0172] Furthermore, if it is determined that the dishwasher does not need to perform the next sequence, the controller performs the following steps.

[0173] In one possible implementation, the controller controls the dishwasher to drain and end the washing program if no further execution of the next sequence is required.

[0174] 405: If the current timing is not required, the controller controls the dishwasher to drain and end the washing program.

[0175] In this context, not needing to execute the current sequence indicates that there is a low amount of organic and / or inorganic residue on the dishes, thus eliminating the need for further rinsing. In some embodiments, the controller can direct the dishwasher to perform a subsequent drying sequence when the current sequence is not executed.

[0176] To illustrate the technical solutions provided in the embodiments of this application, the following description is provided in conjunction with the various optional implementation methods described above and FIG7.

[0177] Referring to Figure 7, taking the application of the technical solution provided in this application embodiment in the rinsing sequence as an example, when the main wash sequence of the washing program begins, the controller controls the dishwasher to initially fill with water. After the initial water filling is completed, the controller obtains the initial first water quality value O0 of the incoming water through an organic matter sensor and the initial second water quality value S0 of the incoming water through a conductivity sensor. The controller executes the main wash sequence, that is, controls the dishwasher to perform high-temperature washing. After the main wash sequence is completed, the controller controls the dishwasher to drain water. After draining is completed, the controller controls the dishwasher to enter the rinsing sequence, controls the dishwasher to fill with water, and controls the water pump to spray water after the water filling is completed, so that the water fully contacts the dishes inside the dishwasher. The controller obtains the first water quality value O1 of the incoming water through an organic matter sensor and the second water quality value S1 of the incoming water through a conductivity sensor. The controller determines whether the first water quality value O1 is greater than the first water quality value threshold O. sv When the first water quality value O1 is greater than the first water quality threshold O sv In this case, the controller determines the rinsing water type as microbubble water, and the controller feeds the dishwasher microbubble water and executes the rinsing sequence, wherein the first water quality threshold value O sv The water quality value is determined based on the initial first water quality value O0, the initial water intake during the main wash cycle, and the water volume in the dishwasher after the rinsing cycle. Upon completion of the rinsing cycle, the controller re-acquires the first water quality value O1 using an organic matter sensor and the second water quality value S1 using a conductivity sensor. After re-acquiring the first water quality value O1 and S1, the controller controls the dishwasher to drain water and re-determines whether the first water quality value O1 is greater than the first water quality threshold value O0. sv And execute the corresponding timing control based on the judgment result.

[0178] Additionally, the first water quality value O1 is less than or equal to the first water quality threshold O. sv In this case, the controller determines whether the second water quality value S1 is greater than the second water quality threshold S. sv Among them, the second water quality threshold S svIt is determined based on the initial second water quality value S0, the initial water intake during the main wash cycle, and the water volume in the dishwasher after the rinsing cycle. When the second water quality value S1 is greater than the second water quality threshold S... sv In this case, the controller determines the rinsing water type as ordinary water, and the dishwasher accepts ordinary water and executes the current sequence. After the rinsing sequence is completed, the controller re-acquires the second water quality value S1 of the incoming water via a conductivity sensor. After re-acquiring the second water quality value S1, the controller controls the dishwasher to drain water and re-determines whether the second water quality value S1 is greater than the second water quality threshold S. sv And execute the corresponding control based on the judgment result.

[0179] Furthermore, if the second water quality value S1 is less than or equal to the second water quality value threshold Ssv, the controller drains the dishwasher and ends the rinsing sequence.
