[0027] 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.

[0028] 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.

[0029] 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.

[0030] Rinse agent: The main function of rinse agent is to reduce the surface tension of water during the rinsing stage of the dishwasher, helping to remove washing residues on the tableware, making the tableware brighter and cleaner.

[0031] Detergent: It is the core consumable in the dishwasher cleaning process, responsible for removing grease and food residues on dishes. Detergents are usually divided into detergent powder, detergent blocks and detergent liquid. Detergent powder is mostly in powder form, and the dosage needs to be adjusted according to the greasiness of the dishes and the water quality of the dishwasher; detergent blocks are pre-mixed with detergent in proportion, and can be directly put into the dishwasher when used, which is convenient and quick; detergent liquid is liquid detergent, suitable for certain specific models of dishwashers.

[0032] Water quality sensor: A sensor used to measure water quality. In an embodiment of the present application, the water quality sensor includes an organic matter sensor and a conductivity sensor. 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.

[0033] The washing process of a dishwasher usually includes pre-wash, main wash, rinsing and drying, which corresponds to the washing program of the dishwasher, including pre-wash sequence, main wash sequence, rinsing sequence and drying sequence. Pre-wash is the first step of the washing process, which aims to remove large particles of food residue on the surface of tableware. This step usually uses lower water pressure and longer washing time to soften and dissolve food residues, preparing for the subsequent formal washing process. The main wash is the core washing program of the dishwasher, using higher water pressure and temperature, and detergent is also added. The rotating arm inside the dishwasher will release a high-pressure water flow, which will be sprayed onto the surface of the tableware through rotation to effectively remove oil stains, food residues and dirt. Rinsing is a program set to remove detergents and foam and other residues generated during the washing process. In this step, the dishwasher will rinse off the detergents and grease and impurities generated during the washing process, so that the tableware is clean and the residual detergent is removed. Drying is the last step of the washing process, using hot air or a heating device to evaporate the water on the surface of the tableware to ensure that the tableware is dry and sterile. Dried tableware can effectively prevent the growth of bacteria and facilitate subsequent storage.

[0034] In the related art, the main wash and rinse sequences of dishwashers are usually fixed, that is, ordinary water (tap water) is directly used for main wash and rinse. However, since the number and type of tableware placed by the user each time and the type of food residue in the tableware may be different, using a fixed type of water for main wash or rinse often results in poor washing results.

[0035] The technical solution provided in the embodiments of the present application can improve the above-mentioned problems, thereby improving the washing effect of the dishwasher.

[0036] 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.

[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 is a schematic diagram of an implementation environment of a dishwasher control method provided in an embodiment of the present application, see Figure 2 , the implementation environment includes a controller 201, a first water quality sensor 202, and a second water quality sensor 203 of the dishwasher. 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 obtain 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, and the first water quality value can reflect the amount of residual organic matter in the water in the dishwasher. In some embodiments, the first water quality sensor 202 is an organic 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, and the second water quality value can reflect the amount of residual inorganic matter in the water in the dishwasher. In some embodiments, the second water quality sensor 203 is an inorganic sensor, such as a conductivity sensor. In some embodiments, see Figure 1 , the first water quality sensor 202 and the second water quality sensor 203 are both 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 first water quality sensor 202 and the second water quality sensor 203 to control the dishwasher and improve the washing effect of the dishwasher. 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.

[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 dishwashers equipped with microbubble components. After adopting the technical solution provided by the embodiment of the present application, when the dishwasher completes the water intake of the current sequence in the washing sequence, the residual concentration of organic matter and the residual concentration of inorganic matter in the water in the dishwasher are used to indirectly indicate the residual amount of organic and inorganic matter on the tableware in the dishwasher. The residual concentration of organic matter and the residual concentration of inorganic matter are used to determine the type of rinse water. The dishwasher is controlled to perform the current sequence based on the type of rinse water, thereby improving the washing effect.

[0039] After introducing the implementation environment and application scenarios of the embodiment of the present application, the washing control method of the dishwasher provided by the embodiment of the present application is described below. Figure 3 Taking the controller of a dishwasher as an example, the method includes the following steps.

[0040] 301. When the dishwasher completes the water intake at the current time sequence in the washing program, the controller obtains a first water quality value and a second water quality value of the water in the dishwasher, wherein the first water quality value is used to indicate the residual amount of organic matter on the tableware, and the second water quality value is used to indicate the residual amount of inorganic matter on the tableware.

[0041] Among them, the washing program includes pre-wash timing, main wash timing, rinse timing and drying timing, and the current timing refers to the main wash timing or the rinse timing. The main wash timing is the main timing for removing stains on the surface of tableware. The rinsing timing is the timing performed after the main wash timing is completed, mainly to remove residual detergent and grease on the tableware and improve the cleanliness of the tableware. The main wash timing and rinse timing water pump will perform multiple rounds of cyclic flushing. In each round of cyclic flushing, the water pump will circulate the water in the dishwasher's water cup into the inner tank of the dishwasher, thereby contacting the tableware in the inner tank to achieve flushing of the tableware. The first water quality value and the second water quality value are different types of water quality values, and the first water quality value and the second water quality value can be obtained through different types of sensors in the dishwasher.

[0042] 302. The controller determines the flushing water type of the current time sequence based on the first water quality value and the second water quality value, and the flushing water type includes micro bubble water and ordinary water.

[0043] Among them, microbubble water has a better flushing effect on organic matter, so it can be used to flush organic matter left on tableware. Microbubble water and ordinary water (tap water) have basically the same flushing effect on inorganic matter, but the production of microbubble water consumes extra energy, so ordinary water can be used to flush inorganic matter. The first water quality value and the second water quality value are used to determine the type of flushing water for the current sequence, so that the type of flushing water used in the current sequence matches the residual situation on the tableware, thereby improving the effect of washing the tableware.

[0044] 303. The controller controls the dishwasher to execute a current timing in a washing program based on the type of flushing water.

[0045] Among them, the type of flushing water matches the residual situation on the tableware. Controlling the dishwasher to wash based on the type of flushing water can better remove the residual organic and / or inorganic matter on the tableware, thereby achieving a better washing effect.

[0046] Through the technical solution provided by the embodiment of the present application, when the dishwasher completes the water intake at the current time sequence in the washing program, the residual concentration of organic matter and the residual concentration of inorganic matter in the water in the dishwasher are used to indirectly indicate the residual amount of organic matter and inorganic matter on the tableware in the dishwasher. The residual concentration of organic matter and the residual concentration of inorganic matter are used to determine the type of flushing water at the current time sequence. Based on the flushing water type, the dishwasher is controlled to execute the current time sequence in the washing program, thereby improving the washing effect.

[0047] The above steps 301-303 are a brief introduction to the washing control method 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.

[0048] 401. When the dishwasher completes the water intake at the current time sequence in the washing program, the controller obtains a first water quality value and a second water quality value of the water in the dishwasher, wherein the first water quality value is used to indicate the residual amount of organic matter on the tableware, and the second water quality value is used to indicate the residual amount of inorganic matter on the tableware.

[0049] Among them, the washing program includes a pre-wash sequence, a main wash sequence, a rinse sequence and a drying sequence. The current sequence refers to the main wash sequence or the rinse sequence. Correspondingly, the water inflow that completes the current sequence refers to the water inflow that completes the main wash sequence or the water inflow that completes the rinse sequence. The main wash sequence is the main sequence for removing stains from the surface of tableware. The rinse sequence is the sequence that is performed after the main wash sequence is completed, mainly to remove residual detergents and grease on the tableware and improve the cleanliness of the tableware. It should be noted that the number of rinse sequences is multiple, and the rinse sequence is a rinse sequence among multiple rinse sequences. For example, the number of rinse sequences is two, which are respectively recorded as the first rinse sequence and the second rinse sequence. Then the above-mentioned rinse sequence refers to any one of the first rinse sequence and the second rinse sequence. The main wash sequence and the rinse sequence water pump will perform multiple rounds of cyclic flushing. In each round of cyclic flushing, the water pump will circulate the water in the dishwasher's water cup into the inner tank of the dishwasher, so that it will contact the tableware in the inner tank to rinse the tableware. The water in the dishwasher is the water after the current sequence has completed water intake and overspraying, so that the water has fully contacted the tableware in the dishwasher. The first water quality value obtained in this way can represent the residual amount of organic matter on the tableware, and the second water quality value can represent the residual amount of inorganic matter on the tableware.

[0050] In a possible implementation, when the dishwasher completes the water intake at the current time sequence in the washing program, the controller obtains the first water quality value through the organic matter sensor in the dishwasher, and the controller obtains the second water quality value through the conductivity sensor in the dishwasher.

[0051] Among them, 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 the spectral sensor is: when light passes through water, light of different wavelengths will be absorbed by different substances in the water to form 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 the first water quality value according to the intensity difference between the light intensity of the emitted light and the light intensity of the received light. The algorithm used by the data processing unit to determine the turbidity by using the intensity difference between the light intensity is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. Of course, the structural composition of the above-mentioned spectral sensor is only an example. In other possible embodiments, the spectral sensor may also include more or fewer components, and the embodiment of the present application does not limit this.

[0052] The working principle of the conductivity sensor mainly depends on the relationship between the ions present in the liquid and the electric current. When the electric current passes through the liquid, the ions will interfere with the flow of the electric current, thereby changing the value of the conductivity. By measuring the change in this conductivity, the sensor can determine the ion concentration in the liquid, thereby realizing the measurement of the conductivity of the liquid. Inorganic matter in water usually exists in the form of ions. The conductivity sensor can measure the conductivity of water, and the conductivity of water can indicate the concentration of ions in the water, thereby realizing the measurement of the concentration of inorganic matter in the water. In some embodiments, the organic matter sensor and the conductivity sensor are arranged in the water cup of the dishwasher. Since the water will fall into the water cup when the water inlet and the water pump are circulating and flushing, such an arrangement can realize the measurement of the water quality value of the water in the dishwasher.

[0053] In this implementation, the first water quality value and the second water quality value of the water in the dishwasher can be directly acquired by using the organic matter sensor and the conductivity sensor, and the acquisition efficiency of the first water quality value and the second water quality value is high.

[0054] For example, when the dishwasher completes the water intake at the current time sequence in the washing program, the controller obtains multiple first initial water quality values ​​through the organic matter sensor in the dishwasher, and different first initial water quality values ​​correspond to different collection times. The controller determines the average value of the multiple first initial water quality values ​​as the first water quality value. The controller obtains multiple second initial water quality values ​​through the conductivity sensor in the dishwasher, and different second initial water quality values ​​correspond to different collection times. The controller determines the average value of the multiple second initial water quality values ​​as the second water quality value.

[0055] In addition, in order to explain the above step 401 more clearly, the water inflow at the current time sequence in the washing program of the dishwasher is explained below.

[0056] In some embodiments, when the dishwasher reaches the current timing in the washing program, the controller controls the dishwasher to let water in. When the water filling is completed, the controller controls the water pump to pump the water in the dishwasher into the inner tank of the dishwasher, that is, to spray, so that the water in the dishwasher is in full contact with the tableware in the dishwasher.

[0057] Among them, a certain spraying time can make the water in the dishwasher fully contact with the tableware in the dishwasher. The spraying time is set by the technician according to the actual situation, such as setting it to 2 minutes or 4 minutes, etc. The embodiment of the present application does not limit this.

[0058] 402. The controller determines whether the current sequence needs to be executed based on the first water quality value and the second water quality value.

[0059] Among them, since the first water quality value and the second water quality value can be used to indicate the residual amount of organic and inorganic matter, and the main wash sequence and the rinse sequence are to remove the residual organic and inorganic matter, the first water quality value and the second water quality value can be used to determine whether the current sequence needs to be executed. Generally speaking, if the residual amount of organic and / or inorganic matter is large, then the current sequence needs to be executed. Correspondingly, if the residual amount of organic and inorganic matter is small, then the current sequence does not need to be executed.

[0060] In a possible implementation, when the first water quality value is greater than the first water quality value threshold, the controller determines that the current sequence needs to be executed. When the first water quality value is less than or equal to the first water quality value threshold, the controller determines whether the second water quality value is greater than the second water quality value threshold. When the second water quality value is greater than the second water quality value threshold, the controller determines that the current sequence needs to be executed. When the second water quality value is less than or equal to the second water quality value threshold, the controller determines that the current sequence does not need to be executed.

[0061] Among them, the first water quality value is greater than the first water quality value threshold, indicating that the residual amount of organic matter is large, so it is necessary to execute the current sequence to remove the residual organic matter. Correspondingly, the second water quality value is greater than the second water quality value threshold, indicating that the residual amount of inorganic matter is large, so it is necessary to execute the current sequence to remove the residual inorganic matter. Of course, the first water quality value is less than or equal to the first water quality value threshold and the second water quality value is less than or equal to the second water quality value threshold, which means that the residual amount of organic matter and inorganic matter is small, so it is not necessary to execute the current sequence. It should be noted that the tableware in the dishwasher usually needs to be cleaned under the main wash sequence. If the result obtained by the above judgment under the main wash sequence is that the main wash sequence does not need to be executed, it means that the water in the dishwasher may not be in full contact with the tableware in the dishwasher. At this time, the controller can control the water pump to spray again, and then execute the above judgment after spraying. Alternatively, the above judgment of whether the current sequence needs to be specified is not performed directly in the main wash sequence, and the subsequent steps of determining the type of flushing water are directly executed, and the embodiment of the present application does not limit this.

[0062] 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 judgment is relatively high.

[0063] In order to explain the above embodiment more clearly, the method of determining the first water quality value threshold and the second water quality value threshold in the above embodiment is explained below.

[0064] First, the method of determining the first water quality value threshold is described.

[0065] In a possible implementation, the washing program includes a main wash sequence and a rinsing sequence, the current sequence is the rinsing sequence, and the controller obtains the initial water intake of the dishwasher and the initial first water quality value of the initial water intake, the initial first water quality value is used to indicate the content of organic matter in the initial water intake. The controller determines the first water quality value threshold based on the initial first water quality value, the initial water intake, and the current water volume in the dishwasher.

[0066] Among them, the initial water intake refers to the amount of water intake during the main wash sequence, or refers to the amount of water intake during the rinse sequence. Accordingly, the initial first water quality value can reflect the water quality conditions in the area where the dishwasher is located, and can be used as a benchmark for determining the first water quality value threshold, that is, the organic matter content reflected by the first water quality value threshold cannot be less than the organic matter content reflected by the initial first water quality value, otherwise it is meaningless to determine the relationship between the first water quality value and the first water quality value threshold. Since the initial first water quality value directly reflects the concentration of organic matter, and the initial water intake and current water volume of the dishwasher are not necessarily the same, in order to improve the accuracy of the first water quality value threshold, the initial water intake and current water volume are used to eliminate the impact of different water volumes on the concentration.

[0067] Under the above-mentioned embodiment, the first water quality value threshold is determined using the initial first water quality value, the initial water intake volume and the current water volume, so that the determined first water quality value threshold is more consistent with the actual situation in 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.

[0068] For example, the controller determines the water inflow of the dishwasher at the initial water inflow in the main wash sequence as the initial water inflow. The controller determines the water quality value of the initial water inflow of the dishwasher at the main wash sequence as the initial first water quality value. The controller multiplies the initial first water quality value by the initial water inflow and divides the result by the current water volume in the dishwasher to obtain the first water quality value threshold.

[0069] Among them, in the above-mentioned embodiment, the first water quality value threshold is equivalent to the conversion of the initial first water quality value under different water volumes. The first water quality value is greater than the first water quality value threshold, indicating that the content of residual organic matter in the water is more than that in the initial influent water, and therefore the current timing needs to be executed to reduce the residual amount of organic matter.

[0070] Based on the above example, there is also the following method for determining the first water quality value threshold.

[0071] For example, when the dishwasher completes the initial water inflow of the main wash sequence, the controller obtains the initial first water quality value through the organic matter sensor in the dishwasher. The controller multiplies the initial first water quality value by the initial water inflow and divides the result by the current water volume in the dishwasher to obtain a first reference water quality value threshold. The controller multiplies the first reference water quality value threshold by a first correction coefficient to obtain the first water quality value threshold, and the first correction coefficient is determined based on the error of the first water quality value and the allowable residual amount of organic matter.

[0072] The error includes a measurement error and a correction error, which can reflect the error of the organic matter sensor when measuring the first water quality value. The allowable residual amount is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. The first correction coefficient is used to introduce the influence of the error and the allowable residual amount in the process of determining the first water quality value threshold, so as to improve the accuracy of the first water quality value threshold.

[0073] In this implementation, the initial first water quality value is not directly equivalent to the first water quality value threshold. Instead, a first correction coefficient determined based on the error and the allowable residual amount is introduced, so that the determined first water quality value threshold is more adapted to the actual situation and has better usability.

[0074] In order to explain the above-mentioned embodiment more clearly, the method of determining the multiplication of the first correction coefficient is described below.

[0075] In some embodiments, the controller adds the measurement error and the correction error of the first water quality value to the target value 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 residual amount to obtain the first correction coefficient. The target value is 1.

[0076] The following describes a method for determining the second water quality value threshold.

[0077] In a possible implementation, the washing program includes a main wash sequence and a rinsing sequence, the current sequence is the rinsing sequence, and the controller obtains the initial water intake of the dishwasher and the initial second water quality value of the initial water intake, the initial second water quality value is used to indicate the content of inorganic matter in the initial water intake. The controller determines the second water quality value threshold based on the initial second water quality value, the initial water intake, and the current water volume in the dishwasher.

[0078] Among them, the initial second water quality value can reflect the water quality of the area where the dishwasher is located, and can be used as a basis for determining the second water quality value threshold, that is, the inorganic content reflected by the second water quality value threshold cannot be less than the inorganic content reflected by the initial second water quality value, otherwise it is meaningless to determine the relationship between the second water quality value and the second water quality value threshold. 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 are not necessarily the same, in order to improve the accuracy of the second water quality value threshold, the initial water intake and current water volume are used to eliminate the influence of different water volumes on the concentration.

[0079] Under the above-mentioned embodiment, the second water quality value threshold is determined using the initial second water quality value, the initial water intake volume and the current water volume, so that the determined second water quality value threshold is more consistent with the actual situation in 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.

[0080] For example, when the dishwasher completes the initial water inflow of the main wash sequence, the controller obtains the initial second water quality value through the conductivity sensor in the dishwasher. The controller multiplies the initial second water quality value by the initial water inflow and divides the result by the current water volume in the dishwasher to obtain the second water quality value threshold.

[0081] Among them, in the above-mentioned embodiment, the second water quality value threshold is equivalent to the conversion of the initial second water quality value under different water volumes. The second water quality value is greater than the second water quality value threshold, indicating that the content of residual inorganic matter in the water is more than that in the initial influent water. Therefore, the current timing needs to be executed to reduce the residual amount of inorganic matter.

[0082] Based on the above example, there is also the following method for determining the second water quality value threshold.

[0083] For example, when the dishwasher completes the initial water inflow of the main wash sequence, the controller obtains the initial second water quality value through the conductivity sensor in the dishwasher. The controller multiplies the initial second water quality value by the initial water inflow and divides the result by the current water volume in the dishwasher to obtain a first reference water quality value threshold. The controller multiplies the first reference water quality value threshold by a second correction coefficient to obtain the second water quality value threshold, and the second correction coefficient is determined based on the error of the second water quality value and the allowable residual amount of inorganic matter.

[0084] The error includes a measurement error and a correction error, which can reflect the error of the conductivity sensor when measuring the second water quality value. The allowable residual amount is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. The second correction coefficient is used to introduce the influence of the error and the allowable residual amount in the process of determining the second water quality value threshold, so as to improve the accuracy of the second water quality value threshold.

[0085] In this implementation, the initial second water quality value is not directly equivalent to the second water quality value threshold. Instead, a second correction coefficient determined based on the error and the allowable residual amount is introduced, so that the determined second water quality value threshold is more adapted to the actual situation and has better usability.

[0086] In order to explain the above-mentioned embodiment more clearly, the method of determining the second correction coefficient multiplication is described below.

[0087] In some embodiments, the controller adds the measurement error and the correction error of the second water quality value to the target value 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 residual amount to obtain the second correction coefficient. The target value is 1.

[0088] Another implementation of the above step 402 is described below.

[0089] In a possible implementation, the controller determines the organic residue concentration corresponding to the first water quality value. When the organic residue concentration is greater than the organic residue concentration threshold, the controller determines that the current sequence needs to be executed. When the organic residue concentration is less than or equal to the organic residue concentration threshold, the controller determines the inorganic residue concentration corresponding to the second water quality value. When the inorganic residue concentration is greater than the inorganic residue concentration threshold, the controller determines that the current sequence needs to be executed. When the inorganic residue concentration is less than or equal to the inorganic residue concentration threshold, the controller determines that the current sequence does not need to be executed.

[0090] 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 judgment accuracy of the current sequence is relatively high.

[0091] The following is a description of the method for determining the residual organic matter concentration and the residual inorganic matter concentration in the above embodiment.

[0092] First, the method of determining the residual organic matter concentration is described.

[0093] In some embodiments, the controller substitutes the first water quality value into first relationship data to obtain the residual organic matter concentration corresponding to the first water quality value, and the first relationship data is used to represent the corresponding relationship between the first water quality value and the residual organic matter concentration.

[0094] The first relationship data is obtained by linearly fitting the first water quality values ​​of multiple samples and the actual residual organic matter concentration corresponding to the first water quality values ​​of each sample. Therefore, substituting the first water quality value into the first relationship data can obtain the corresponding residual organic matter concentration.

[0095] The method for determining the residual inorganic matter concentration is described below.

[0096] In some embodiments, the controller substitutes the second water quality value into second relationship data to obtain the organic matter residual concentration corresponding to the second water quality value, and the second relationship data is used to represent the corresponding relationship between the second water quality value and the inorganic matter residual concentration.

[0097] The second relationship data is obtained by linearly fitting the second water quality values ​​of multiple samples and the actual inorganic residual concentration corresponding to the second water quality value of each sample. Therefore, substituting the second water quality value into the second relationship data can obtain the corresponding inorganic residual concentration.

[0098] In order to explain the above embodiment more clearly, the method of determining the organic matter residual concentration threshold and the inorganic matter residual concentration threshold in the above embodiment is explained below.

[0099] First, the method of determining the threshold value of the residual organic matter concentration is described.

[0100] In a possible implementation, the controller obtains the initial water intake of the dishwasher and the initial first water quality value of the initial water intake, where the initial first water quality value is used to indicate the content of organic matter in the initial water intake. The controller determines the initial organic matter residual concentration corresponding to the initial first water quality value. The controller determines the organic matter residual concentration threshold value based on the initial organic matter residual concentration, the initial water intake, and the current water volume in the dishwasher.

[0101] Among them, the initial residual organic matter concentration can reflect the water quality of the area where the dishwasher is located, and can be used as a benchmark for determining the threshold value of the residual organic matter concentration. That is, the organic matter content reflected by the threshold value of the residual organic matter concentration cannot be less than the initial residual organic matter concentration, otherwise it is meaningless to determine the relationship between the residual organic matter concentration corresponding to the first water quality value and the threshold value of the residual organic matter concentration. 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 are not necessarily the same, in order to improve the accuracy of the threshold value of the residual organic matter concentration, the initial water intake and current water volume are used to eliminate the influence of different water volumes on the concentration.

[0102] Under the above-mentioned embodiment, the initial organic matter residual concentration corresponding to the initial first water quality value, the initial water intake volume and the current water volume are used to determine the organic matter residual concentration threshold, so that the determined organic matter residual concentration threshold is more consistent with the actual situation in the dishwasher and the water quality of the area where the dishwasher is located, and the accuracy of the organic matter residual concentration threshold is better.

[0103] For example, when the dishwasher completes the initial water inflow of the main wash sequence, the controller obtains the initial first water quality value through the organic matter sensor in the dishwasher. The controller substitutes the initial first water quality value into the first relationship data to obtain the initial organic matter residual concentration corresponding to the initial first water quality value. The controller multiplies the initial organic matter residual concentration by the initial water inflow and divides the result by the current water volume in the dishwasher to obtain the organic matter residual concentration threshold.

[0104] Among them, in the above-mentioned embodiment, the residual organic matter concentration threshold is equivalent to the conversion of the initial residual organic matter concentration under different water volumes. The residual organic matter concentration is greater than the residual organic matter concentration threshold, which means that the content of residual organic matter in the water is more than that in the initial influent water. Therefore, the current timing needs to be executed to reduce the residual amount of organic matter.

[0105] Based on the above examples, there is also the following method for determining the threshold value of residual organic matter concentration.

[0106] For example, when the dishwasher completes the initial water inflow of the main wash sequence, the controller obtains the initial first water quality value through the organic matter sensor in the dishwasher. The controller substitutes the initial first water quality value into the first relationship data to obtain the initial organic matter residual concentration corresponding to the initial first water quality value. The controller multiplies the initial organic matter residual concentration by the initial water inflow and then divides the result by the current water volume in the dishwasher to obtain a first reference organic matter residual concentration threshold. The controller multiplies the first reference organic matter residual concentration threshold by a first correction coefficient to obtain the organic matter residual concentration threshold, and the first correction coefficient is determined based on the error of the first water quality value and the allowable residual amount of organic matter.

[0107] The error includes a measurement error and a correction error, which can reflect the error of the organic matter sensor when measuring the first water quality value. The allowable residual amount is set by the technician according to the actual situation, and the embodiment of the present application does not limit this. The first correction coefficient is used to introduce the influence of the error and the allowable residual amount in the process of determining the organic matter residual concentration threshold, so as to improve the accuracy of the organic matter residual concentration threshold.

[0108] In this implementation, the initial organic matter residual concentration corresponding to the initial first water quality value is not directly equivalent to the organic matter residual concentration threshold. Instead, a first correction coefficient determined based on the error and the allowable residual amount is introduced, so that the determined organic matter residual concentration threshold is more adapted to the actual situation and has better usability.

[0109] The method for determining the inorganic residual concentration threshold is described below.

[0110] In a possible implementation, the controller obtains the initial water intake of the dishwasher and the initial second water quality value of the initial water intake, the initial second water quality value being used to indicate the content of inorganic matter in the initial water intake. The controller determines the initial inorganic residual concentration corresponding to the initial second water quality value. The controller determines the inorganic residual concentration threshold value based on the initial inorganic residual concentration, the initial water intake, and the current water volume in the dishwasher.

[0111] Among them, the initial inorganic residual concentration can reflect the water quality of the area where the dishwasher is located, and can be used as a basis for determining the inorganic residual concentration threshold. That is, the inorganic content reflected by the inorganic residual concentration threshold cannot be less than the initial inorganic residual concentration, otherwise it is meaningless to determine the relationship between the inorganic residual concentration corresponding to the second water quality value and the inorganic residual concentration threshold. Since the initial inorganic residual concentration directly reflects the concentration of inorganic matter, and the initial water intake and current water volume of the dishwasher are not necessarily the same, in order to improve the accuracy of the inorganic residual concentration threshold, the initial water intake and current water volume are used to eliminate the impact of different water volumes on the concentration.

[0112] Under the above-mentioned implementation mode, the initial inorganic residual concentration corresponding to the initial second water quality value, the initial water intake volume and the current water volume are used to determine the inorganic residual concentration threshold, so that the determined inorganic residual concentration threshold is more consistent with the actual situation in the dishwasher and the water quality of the area where the dishwasher is located, and the accuracy of the inorganic residual concentration threshold is better.

[0113] For example, when the dishwasher completes the initial water inflow of the main wash sequence, the controller obtains the initial second water quality value through the inorganic sensor in the dishwasher. The controller substitutes the initial second water quality value into the second relationship data to obtain the initial inorganic residual concentration corresponding to the initial second water quality value. The controller multiplies the initial inorganic residual concentration by the initial water inflow and divides the result by the current water volume in the dishwasher to obtain the inorganic residual concentration threshold.

[0114] Among them, in the above-mentioned embodiment, the inorganic residual concentration threshold is equivalent to the conversion of the initial inorganic residual concentration under different water volumes. The inorganic residual concentration is greater than the inorganic residual concentration threshold, which means that the content of residual inorganic matter in the water is more than that in the initial influent water. Therefore, the current timing needs to be executed to reduce the residual amount of inorganic matter.

[0115] Based on the above examples, there is also the following method for determining the threshold value of inorganic residue concentration.

[0116] For example, when the dishwasher completes the initial water inflow of the main wash sequence, the controller obtains the initial second water quality value through the inorganic sensor in the dishwasher. The controller substitutes the initial second water quality value into the second relationship data to obtain the initial inorganic residual concentration corresponding to the initial second water quality value. The controller multiplies the initial inorganic residual concentration by the initial water inflow and divides the result by the current water volume in the dishwasher to obtain a second reference inorganic residual concentration threshold. The controller multiplies the second reference inorganic residual concentration threshold by a second correction coefficient to obtain the inorganic residual concentration threshold, and the second correction coefficient is determined based on the error of the second water quality value and the allowable residual amount of inorganic matter.

[0117] The error includes measurement error and correction error, which can reflect the error of the inorganic sensor when measuring the second water quality value. The allowable residual amount is set by the technician according to the actual situation, and the embodiment of the present application 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 inorganic residual concentration threshold, so as to improve the accuracy of the inorganic residual concentration threshold.

[0118] Under this implementation, the initial inorganic residual concentration corresponding to the initial second water quality value is not directly equivalent to the inorganic residual concentration threshold. Instead, a second correction coefficient determined based on the error and the allowable residual amount is introduced, so that the determined inorganic residual concentration threshold is more adapted to the actual situation and has better usability.

[0119] It should be noted that after step 403, the controller executes the following steps 403 and 404, or executes the following step 405 according to actual conditions, which is not limited in the embodiment of the present application.

[0120] 403. When the current sequence needs to be executed, the controller determines the flushing water type of the current sequence based on the first water quality value and the second water quality value, and the flushing water type includes micro bubble water and ordinary water.

[0121] Among them, the need to execute the current sequence means that there is a large amount of organic and / or inorganic residues on the tableware. Microbubble water has a better flushing effect on organic matter, so it can be used to flush the organic matter remaining on the tableware. Microbubble water and ordinary water (tap water) have basically the same flushing effect on inorganic matter, but the production of microbubble water requires additional energy, so ordinary water can be used to flush inorganic matter. The first water quality value and the second water quality value are used to determine the type of flushing water, so that the type of flushing water used to execute the current sequence matches the residual situation on the tableware, thereby improving the effect of washing the tableware.

[0122] In a possible implementation, when the current sequence needs to be executed and the first water quality value is greater than the first water quality value threshold, the controller determines the flushing water type as micro bubble water. When the first water quality value is less than or equal to the first water quality value threshold and the second water quality value is greater than the second water quality value threshold, the controller determines the flushing water type as ordinary water.

[0123] Among them, microbubble water contains a large number of microbubbles. When these microbubbles burst in the water, they will form a high-pressure shock wave. This shock wave has a strong cleaning ability and can effectively remove organic matter on the surface of tableware. Since microbubble water has a better rinsing effect on organic matter, when there is a large amount of organic residue, the amount of inorganic residue is no longer determined, and the type of rinsing water is directly determined as microbubble water. Microbubble water can be used to rinse both organic and inorganic matter. When there is a small amount of organic residue and a large amount of inorganic residue, the type of rinsing water is determined as ordinary water, and there is no need to consume energy to produce microbubble water.

[0124] In this embodiment, the residual amount of organic and inorganic matter is used to determine the type of rinsing water, so that the water used when executing the current sequence is more closely matched with the actual residual situation of the dishes in the dishwasher, thereby improving the rinsing effect of the current sequence.

[0125] Another implementation of the above step 403 is described below.

[0126] In a possible implementation, when the current sequence needs to be executed and the organic matter residual concentration corresponding to the first water quality value is greater than the organic matter residual concentration threshold, the controller determines the flushing water type as microbubble water. When the organic matter residual concentration corresponding to the first water quality value is less than or equal to the organic matter residual concentration threshold and the inorganic matter residual concentration corresponding to the second water quality value is greater than the inorganic matter residual concentration threshold, the controller determines the flushing water type as ordinary water.

[0127] Among them, the method of determining the organic / inorganic residual concentration corresponding to the water quality value belongs to the same inventive concept as the description in the second implementation of the above step 402. The implementation process refers to the relevant description in the above step 402 and will not be repeated here.

[0128] 404. The controller controls the dishwasher to execute a current timing in a washing program based on the type of rinse water.

[0129] Among them, the type of flushing water matches the residual situation on the tableware. Controlling the dishwasher to execute the current timing based on the type of flushing water can better remove the organic and / or inorganic matter remaining on the tableware, thereby achieving a better washing effect.

[0130] In a possible implementation, when the type of flushing water is microbubble water, the controller controls the dishwasher to take in microbubble water from a microbubble assembly, where the microbubble assembly is used to generate microbubble water. When the microbubble water has been taken in, the controller controls the water pump of the dishwasher to run to execute the current sequence.

[0131] In the embodiment of the present application, the microbubble water is generated by the microbubble component of the dishwasher, see Figure 5 The microbubble assembly 50 includes an air dissolving chamber 51, a bypass piece 52, a connecting pipe 524, a bubbler 53, a liquid inlet valve 54 and a vent valve 55. Gas and liquid can be mixed in the air dissolving chamber 51, and then bubbles are generated through the bubbler 53 to form microbubble water. In some embodiments, the air dissolving chamber 51 has an air vent, a liquid inlet and a liquid outlet. Gas can enter the air dissolving chamber 51 through the air vent, and liquid can enter the air dissolving chamber 51 through the liquid inlet. The gas and liquid entering the air dissolving chamber 51 can be mixed, so that a certain amount of gas is mixed in the liquid to complete the gas dissolution. The bubbler 53 is connected to the liquid outlet. In other words, the gas-liquid mixed fluid in the air dissolving chamber 51 enters the bubbler 53 through the liquid outlet. The action of the bubbler 53 causes the gas in the gas-liquid mixed fluid to be broken up to form bubbles, thereby forming a large number of tiny bubbles in the liquid to obtain microbubble water. In some embodiments, see Figure 6 The microbubble assembly 50 is installed on the side of the dishwasher. The arrow pointing to the microbubble assembly 50 represents water inflow, and the arrow pointing from the microbubble assembly 50 to the outside represents water outflow into the inner tank of the dishwasher.

[0132] In this embodiment, when microbubble water is needed, the dishwasher is controlled to let water in from the microbubble component, and after the water inlet is completed, 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.

[0133] For example, when the type of rinsing water is microbubble water, the controller determines a first water inflow of microbubble water based on the first water quality value and the initial first water quality value of the dishwashing water, and controls the dishwasher to take in microbubble water from the microbubble assembly according to the first water inflow.

[0134] Among them, the first water quality value is used to indicate the current organic matter concentration of the water in the dishwasher, and the initial first water quality value is the organic matter concentration of the dishwasher inlet water, which can be regarded as a benchmark for the organic matter concentration. The first water quality value and the initial first water quality value are used to determine the first water inlet volume, so that the first water inlet volume when executing the current sequence matches the residual amount of organic matter in the dishwasher, thereby improving the rinsing effect of the current sequence.

[0135] The above method of determining the first water inflow amount is described below.

[0136] In a 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 the first water quality value difference, the controller determines the first water inflow, and the first water inflow is positively correlated with the first water quality value difference.

[0137] Among them, compared with the first water quality value, the first water quality value difference can more accurately reflect the amount of organic matter residue on the tableware in the dishwasher, because the first water quality value difference excludes the influence of the organic matter content in the initial water inlet. Accordingly, the larger the first water quality value difference, the more organic matter residue on the tableware in the dishwasher; the smaller the first water quality value difference, the less organic matter residue on the tableware in the dishwasher. The first water inflow is positively correlated with the first water quality value difference, which means that the larger the first water quality value difference, the larger the first water inflow; the smaller the first water quality value difference, the smaller the first water inflow.

[0138] In this embodiment, the first water quality value difference is used to determine the first water intake volume, and the first water intake volume is adapted to the amount of organic matter residue on the tableware, which can improve the flushing effect of the organic matter.

[0139] For example, the controller subtracts the first water quality value from the initial first water quality value to obtain a first water quality value difference. The controller substitutes the first water quality value difference into the third relational data to obtain the first water inflow, and the third relational data is used to represent the corresponding relationship between the first water quality value difference and the first water inflow. Alternatively, the controller uses the first water quality value difference to query in a first relational table to obtain the first water inflow, and the first relational table stores a plurality of first water quality value differences and the first water inflow corresponding to each first water quality value difference.

[0140] Among them, the third relationship data and the first relationship table are set by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0141] In addition, when the current timing is a rinsing timing, the above step 404 is that the controller controls the dishwasher to execute the rinsing timing in the washing program based on the type of rinse water; or, when the current timing is a main wash timing, the controller controls the dishwasher to execute the main wash timing in the washing program based on the type of rinse water.

[0142] Another implementation of the above step 404 is described below.

[0143] In a possible implementation, when the type of flushing water is ordinary water, the controller controls the dishwasher to take in ordinary water from the water inlet pipe. When the ordinary water intake is complete, the controller controls the water pump of the dishwasher to run to execute the current sequence.

[0144] In this implementation, when ordinary water is needed, the dishwasher is controlled to directly let water in from the water inlet pipe of the dishwasher. After the water inlet is completed, the water pump is controlled to run to execute the current sequence, thereby achieving the purpose of using ordinary water to execute the current sequence.

[0145] For example, when the type of flushing water is ordinary water, the controller determines the second water inflow of ordinary water based on the second water quality value and the initial second water quality value of the dishwashing water, and controls the dishwasher to take in ordinary water from the water inlet pipe according to the second water inflow.

[0146] Among them, the second water quality value is used to indicate 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 quality value and the initial second water quality value are used to determine the second water inlet volume, so that the second water inlet volume of the current time sequence matches the residual amount of inorganic matter in the dishwasher, thereby improving the rinsing effect of the current time sequence.

[0147] The above method of determining the second water inflow rate is described below.

[0148] In a possible implementation, the controller determines a second water quality value difference between the second water quality value and the initial second water quality value, and determines the second water inflow based on the second water quality value difference, wherein the second water inflow is positively correlated with the second water quality value difference.

[0149] Among them, compared with the second water quality value, the second water quality value difference can more accurately reflect the amount of inorganic residue on the tableware in the dishwasher, because the second water quality value difference excludes the influence of the inorganic content in the initial water intake. Accordingly, the larger the second water quality value difference, the more inorganic residue on the tableware in the dishwasher; the smaller the second water quality value difference, the less inorganic residue on the tableware in the dishwasher. The second water intake is positively correlated with the second water quality value difference, which means that the larger the second water quality value difference, the larger the second water intake; the smaller the second water quality value difference, the smaller the second water intake.

[0150] In this embodiment, the second water quality value difference is used to determine the second water intake volume, and the second water intake volume is adapted to the amount of inorganic residues on the tableware, thereby improving the flushing effect on the inorganic residues.

[0151] For example, the controller subtracts the second water quality value from the initial second water quality value to obtain a second water quality value difference. The controller substitutes the second water quality value difference into the fourth relational data to obtain the second water inflow, and the fourth relational data is used to represent the corresponding relationship between the second water quality value difference and the second water inflow. Alternatively, the controller uses the second water quality value difference to query in a second relational table to obtain the second water inflow, and the second relational table stores a plurality of second water quality value differences and the second water inflow corresponding to each second water quality value difference.

[0152] Among them, the fourth relationship data and the second relationship table are set by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0153] Optionally, after step 404, the controller can also perform the following steps.

[0154] In a possible implementation, when the current sequence is completed, the controller reacquires the first water quality value and the second water quality value of the water in the dishwasher. Based on the reacquired first water quality value and the reacquired second water quality value, the controller determines whether the dishwasher executes the next sequence, which is the rinsing sequence.

[0155] Among them, no matter the current timing is the main wash timing or the rinse timing, the next timing is the rinse timing.

[0156] That is, when the current sequence is completed, the first water quality value and the second water quality value that are newly acquired are used to determine whether a rinsing sequence needs to be executed, so as to avoid the current sequence failing to achieve the standard rinsing effect on the dishes in the dishwasher.

[0157] For example, when the current sequence is completed, the controller reacquires the first water quality value and the second water quality value of the water in the dishwasher. When the reacquired first water quality value is greater than the first water quality value threshold, the controller determines that the next sequence needs to be executed. When the reacquired first water quality value is less than or equal to the first water quality value threshold, the controller determines whether the reacquired second water quality value is greater than the second water quality value threshold. When the reacquired second water quality value is greater than the second water quality value threshold, the controller determines that the next sequence needs to be executed. When the reacquired second water quality value is less than or equal to the second water quality value threshold, the controller determines that the next sequence does not need to be executed.

[0158] In some embodiments, when the current sequence is executed when the first water quality value is greater than the first water quality value threshold, then when judging whether the next sequence needs to be executed, it is necessary to first judge the relationship between the reacquired first water quality value and the first water quality value threshold, and then judge the relationship between the reacquired second water quality value and the second water quality value threshold in the manner described in the above example, so as to determine whether the next sequence needs to be executed. When the current sequence is executed when the second water quality value is greater than the second water quality value threshold, then when judging whether the next sequence needs to be executed, it is not necessary to judge the relationship between the reacquired first water quality value and the first water quality value threshold, and it is sufficient to directly determine whether the next sequence needs to be executed based on the relationship between the reacquired second water quality value and the second water quality value threshold.

[0159] In addition, based on the above embodiment, when it is determined that the dishwasher needs to execute the next sequence, the controller can also execute the following steps.

[0160] In a possible implementation, the controller determines the type of flushing water for the next time sequence based on the first water quality value and the second water quality value that are retrieved, and controls the dishwasher to execute the next time sequence in the washing program based on the flushing water type.

[0161] Also, in the case where it is determined that the dishwasher does not need to execute the next sequence, the controller performs the following steps.

[0162] In a possible implementation, when there is no need to execute the next sequence, the controller controls the dishwasher to drain water and end the washing program.

[0163] 405. When there is no need to execute the current sequence, the controller controls the dishwasher to drain water and end the washing program.

[0164] The fact that the current sequence does not need to be executed means that the residual amount of organic and / or inorganic matter on the dishes is small, so there is no need to waste resources for rinsing. In some embodiments, when the current sequence is not executed, the controller can control the dishwasher to perform a subsequent drying sequence.

[0165] In order to illustrate the technical solution provided by the embodiment of the present application, the following is combined with the above-mentioned optional implementation modes and Figure 7 The technical solution provided in the embodiments of the present application is described.

[0166] See also Figure 7 Taking the application of the technical solution provided by the embodiment of the present application in the rinsing sequence as an example, when the main wash sequence of the washing program starts, the controller controls the dishwasher to perform initial water inflow. When the initial water inflow is completed, the organic matter sensor obtains the initial first water quality value of the inflow water. 0The conductivity sensor is used to obtain the initial second water quality value S of the incoming water. 0 The controller executes the main wash sequence, that is, controls the dishwasher to perform high-temperature washing. When the main wash sequence is completed, the controller controls the dishwasher to drain water. When the drainage is completed, the dishwasher is controlled to enter the rinsing sequence, control the dishwasher to fill with water, and control the water pump to spray after the water filling is completed, so that the water is fully in contact with the dishes in the dishwasher. The controller obtains the first water quality value of the incoming water through the organic matter sensor. 1 The second water quality value S of the inlet water is obtained through the conductivity sensor 1 The controller determines the first water quality value O 1 Is it greater than the first water quality value threshold O sv , at the first water quality value O 1 Greater than the first water quality value threshold O sv In the case of, the controller determines the type of flushing water as micro-bubble water, controls the dishwasher to enter micro-bubble water and executes the rinsing sequence, wherein the first water quality value threshold value O sv is based on the initial first water quality value O 0 , the initial water inflow of the main wash sequence, and the water volume in the dishwasher after the water inflow of the rinse sequence. When the rinse sequence is completed, the controller re-acquires the first water quality value of the inflow through the organic matter sensor. 1 The second water quality value S of the inlet water is obtained again through the conductivity sensor 1 After re-obtaining the first water quality value O 1 and S 1 Afterwards, the controller controls the dishwasher to drain water and re-determines the first water quality value. 1 Is it greater than the first water quality value threshold O sv , and execute corresponding timing control according to the judgment result.

[0167] In addition, at the first water quality value O 1 Less than or equal to the first water quality value threshold O sv In the case of 1 Is it greater than the second water quality value threshold S sv , where the second water quality value threshold S sv is based on the initial second water quality value S 0 , the initial water inflow of the main wash sequence, and the water volume in the dishwasher after the water inflow of the rinse sequence. 1 Greater than the second water quality value threshold S sv In the case of , the controller determines the type of flushing water as ordinary water, controls the dishwasher to feed ordinary water and executes the current sequence. When the rinsing sequence is completed, the controller re-acquires the second water quality value S of the incoming water through the conductivity sensor. 1 After re-obtaining the second water quality value S1 Afterwards, the controller controls the dishwasher to drain water and re-determines the second water quality value S 1 Is it greater than the second water quality value threshold S sv , and execute corresponding control according to the judgment result.

[0168] Also, at the second water quality value S 1 Less than or equal to the second water quality value threshold S sv In this case, the controller drains the dishwasher and ends the rinse sequence.

[0169] 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.

[0170] Through the technical solution provided by the embodiment of the present application, when the dishwasher completes the water intake at the current time sequence in the washing program, the residual concentration of organic matter and the residual concentration of inorganic matter in the water in the dishwasher are used to indirectly indicate the residual amount of organic matter and inorganic matter on the tableware in the dishwasher. The residual concentration of organic matter and the residual concentration of inorganic matter are used to determine the type of flushing water at the current time sequence. Based on the flushing water type, the dishwasher is controlled to execute the current time sequence in the washing program, thereby improving the washing effect.

[0171] Figure 8 is a structural schematic diagram of a washing control device for a dishwasher provided in an embodiment of the present application, see Figure 8 , the device comprises:
