[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The disinfectant preparation machine control method provided in the embodiment of the present application is used to control the disinfectant preparation machine. Among them, the disinfectant preparation machine can be a glow discharge disinfectant preparation machine. The glow discharge disinfectant preparation machine adopts glow discharge technology to prepare plasma-rich disinfectant. Glow discharge technology is a technology that generates plasma during gas discharge. After the plasma and active substances generated by glow discharge are dissolved in water, a disinfectant with disinfection ability can be formed. Figure 1 As shown, the disinfectant preparation machine includes a water inlet pipe, a solenoid valve, a disinfectant manufacturing box, a check valve, an air pump, a magnesium rod and a water pump. The water inlet pipe, the vent pipe and the water outlet pipe are connected to the disinfectant manufacturing box. The solenoid valve is arranged on the water inlet pipe, the check valve and the air pump are arranged on the vent pipe, the water pump is arranged on the water outlet pipe, and the magnesium rod is arranged on the disinfectant manufacturing box. The disinfectant manufacturing box is provided with an air bubble stone and a glass tube arranged on the air bubble stone, and an electrode is arranged in the glass tube. When the disinfectant preparation machine is working, the check valve is opened, and the gas enters the disinfectant manufacturing box through the air pump, and the electrode rod is energized. After the air is ionized, it is blown into the air bubble stone to generate a large number of bubbles and then contact with water. The bubbles are more soluble in water, and the prepared disinfectant is output through the water outlet pipe and the water pump for use by the user. Exemplarily, the water outlet pipe can be connected to the inner tank of the dishwasher, and the disinfectant prepared by the disinfectant preparation machine can enter the inner tank of the dishwasher to disinfect and wash the dishes.

[0052] The disinfectant preparation machine control method can be executed by a controller inside the disinfectant preparation machine, or by a terminal or server that is connected to the disinfectant preparation machine. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. In an exemplary embodiment, Figure 2 As shown, a disinfectant preparation machine control method is provided, which is described by taking the method executed by a controller inside the disinfectant preparation machine as an example, and includes steps 202 to 208.

[0053] Step 202, obtaining the oxidation-reduction potential value of the disinfectant.

[0054] The disinfectant is a disinfectant prepared by a disinfectant preparation machine. Taking the structure of the disinfectant preparation machine including a water inlet pipe, a solenoid valve, a disinfectant manufacturing box, a check valve, an air pump, a magnesium rod and a water pump as an example, the disinfectant is the liquid in the disinfectant manufacturing box, and can also be the liquid in the water outlet pipe.

[0055] The redox potential value of the disinfectant can be detected by the redox potential detection device and sent to the controller. The redox potential detection device can be set in the disinfectant manufacturing box of the disinfectant preparation machine to detect the redox potential value of the liquid in the disinfectant manufacturing box. The redox potential detection device is also connected to the controller for data exchange with the controller.

[0056] The number of oxidation-reduction potential detection devices is not unique. For example, the number of oxidation-reduction potential devices can be more than two, and different oxidation-reduction potential detection devices are arranged at different positions, and are used to detect the oxidation-reduction potential value of the disinfectant at different positions and send it to the controller. The controller can analyze each received oxidation-reduction potential value to obtain the final detection result of the oxidation-reduction potential value. For example, the controller uses the average value of each received oxidation-reduction potential value as the final detection result of the oxidation-reduction potential value. By setting a plurality of oxidation-reduction potential detection devices, the accuracy of the detected oxidation-reduction potential value can be improved. It can be understood that in other embodiments, the number of oxidation-reduction potential detection devices can also be one to save hardware resources.

[0057] The type of redox potential detection device is also not limited, for example, it can be an ORP (Oxidation-Reduction Potential) meter. ORP determines the ORP value by measuring the potential difference of the redox pair in the solution. The ORP meter usually consists of a reference electrode and a working electrode, which are placed in the solution to be tested. The working electrode is a sensitive electrode that reacts with the oxidant and reductant in the solution, while the reference electrode provides a stable reference potential. By measuring the potential difference between the two electrodes, the ORP meter can calculate the redox potential of the solution.

[0058] The oxidation-reduction potential detection device can detect the oxidation-reduction potential value in real time, and the controller can also receive the oxidation-reduction potential value from the oxidation-reduction potential detection device in real time, so as to continuously monitor the oxidation-reduction potential value of the disinfectant, which is more conducive to improving the quality of the disinfectant. Alternatively, in other embodiments, the oxidation-reduction potential detection device can also detect the oxidation-reduction potential value at a certain time interval, and the controller can also receive the oxidation-reduction potential value from the oxidation-reduction potential detection device at a certain time interval, so as to reduce the amount of interactive data and reduce the workload of the device.

[0059] Step 204, obtaining the pH value of the disinfectant.

[0060] The pH value of the disinfectant can also be called the pH value of the disinfectant. The pH value of the disinfectant can be detected by the acid-base detection device and sent to the controller. The acid-base detection device can be arranged in the disinfectant manufacturing box of the disinfectant preparation machine to detect the pH value of the liquid in the disinfectant manufacturing box. The acid-base detection device is also connected to the controller for data exchange with the controller.

[0061] The number of acid-base detection devices is not unique. For example, the number of acid-base detection devices can be more than two, and different acid-base detection devices are set at different positions to detect the pH value of the disinfectant at different positions and send it to the controller. The controller can analyze the received pH values ​​to obtain the final pH value detection result. For example, the controller uses the average value of the received pH values ​​as the final pH value detection result. The accuracy of the detected pH value can be improved by setting multiple acid-base detection devices. It can be understood that in other embodiments, the number of acid-base detection devices can also be one to save hardware resources.

[0062] There are also different types of acid-base detection devices. For example, the acid-base detection device can be a pH meter. The pH meter measures the pH value of a solution by potentiometric method. The pH meter mainly consists of two parts: an electrode and an electric meter. Its working principle is to measure the pH value of a solution by potentiometric method based on a pH indicator electrode. Specifically, a pH indicator electrode (usually a glass electrode and a reference electrode) is inserted into the solution to be tested to form a galvanic cell, and the pH value of the solution is calculated by measuring the change in electrode potential.

[0063] The acid-base detection device can detect the acid-base value in real time, and the controller can also receive the acid-base value from the acid-base detection device in real time, so as to continuously monitor the acid-base value of the disinfectant, which is more conducive to improving the quality of the disinfectant. Alternatively, in other embodiments, the acid-base detection device can also detect the acid-base value at a certain time interval, and the controller can also receive the acid-base value from the acid-base detection device at a certain time interval, so as to reduce the amount of interactive data and reduce the workload of the device.

[0064] Step 206, determining the disinfection ability parameter of the disinfectant according to the oxidation-reduction potential value and the pH value.

[0065] Both the redox potential value and the pH value can characterize the disinfection ability of the disinfectant. By processing the numerical values ​​of the redox potential value and the pH value, a disinfection ability parameter characterizing the disinfection ability of the disinfectant can be obtained. The type of the disinfection ability parameter is not limited. For example, it can be a fraction. The larger the fraction, the stronger the disinfection ability of the disinfectant. It is understood that the disinfection ability parameter can also be other types, as long as those skilled in the art believe that it can be achieved.

[0066] Step 208, controlling the working state of the disinfectant preparation machine according to the disinfection capacity parameter.

[0067] After obtaining the disinfection ability parameter that can characterize the disinfection ability of the disinfectant, the working state of the disinfectant preparation machine can be controlled according to the disinfection ability parameter. For example, when the disinfection ability parameter characterizes that the disinfection ability of the disinfectant is strong, the disinfectant preparation machine can be controlled to stop working or reduce the power to save energy. When the disinfection ability parameter characterizes that the disinfection ability of the disinfectant is weak, the disinfectant preparation machine can be controlled to work or increase the power to prepare more disinfectant and improve the disinfection ability of the disinfectant.

[0068] The above-mentioned disinfectant preparation machine control method obtains the redox potential value and pH value of the disinfectant prepared by the disinfectant preparation machine, determines the disinfection ability parameter of the disinfectant according to the redox potential value and pH value, and controls the working state of the disinfectant preparation machine according to the disinfection ability parameter. The disinfection ability of the disinfectant can be effectively and timely judged by the redox potential value and pH value, and the working state of the disinfectant preparation machine can be controlled according to the test results, which can improve the performance of the disinfectant prepared by the disinfectant preparation machine, not only improve the disinfection effect, but also reduce the harmfulness of the disinfectant, thereby improving the reliability of the use of the disinfectant.

[0069] In an exemplary embodiment, Figure 3 As shown, step 206 includes steps 302 to 306 .

[0070] Step 302: Determine a first disinfection capability parameter of the disinfectant according to the oxidation-reduction potential value.

[0071] The redox potential value can reflect the potential difference of the redox pair in the disinfectant. Generally, the larger the redox potential value, the stronger the disinfection ability of the disinfectant; the smaller the redox potential value, the weaker the disinfection ability of the disinfectant. According to the numerical value of the redox potential value, the first disinfection ability parameter of the disinfectant can be determined.

[0072] Step 304, determining a second disinfection capability parameter of the disinfectant according to the pH value.

[0073] The pH value can reflect the acidity and alkalinity of the disinfectant, as well as the magnitude of the pH value. Generally, when the pH value indicates that the disinfectant is acidic, the smaller the pH value, the stronger the disinfection ability of the disinfectant. When the pH value indicates that the disinfectant is alkaline, the smaller the pH value, the stronger the disinfection ability of the disinfectant. According to the numerical value of the pH value, the second disinfection ability parameter of the disinfectant can be determined.

[0074] Step 306, determining a disinfection capability parameter according to the first disinfection capability parameter and the second disinfection capability parameter.

[0075] After determining the first disinfection ability parameter and the second disinfection ability parameter of the disinfectant, the disinfection ability parameter can be determined according to different rules. Exemplarily, the sum of the first disinfection ability parameter and the second disinfection ability parameter can be used as the disinfection ability parameter, so that the disinfection ability parameter can reflect both the influence of the redox potential value on the disinfection ability of the disinfectant and the influence of the pH value on the disinfection ability. It is understood that in other embodiments, the disinfection ability parameter can also be determined based on the first disinfection ability parameter and the second disinfection ability parameter based on other rules, which are not limited here.

[0076] In this embodiment, the first disinfection ability parameter of the disinfectant is determined according to the redox potential value, the second disinfection ability parameter of the disinfectant is determined according to the pH value, and the disinfection ability parameter is determined according to the first disinfection ability parameter and the second disinfection ability parameter. Thus, after obtaining the first disinfection ability parameter and the second disinfection ability parameter based on the redox potential value and the pH value, respectively, the disinfection ability parameter is determined according to the first disinfection ability parameter and the second disinfection ability parameter, so that the disinfection ability parameter can reflect both the influence of the redox potential value on the disinfection ability of the disinfectant and the influence of the pH value on the disinfection ability. Thus, after the working state of the disinfectant preparation machine is subsequently controlled based on the disinfection ability parameter, the working state of the disinfectant preparation machine can better meet the actual needs, and the disinfectant prepared by the disinfectant preparation machine can also better meet the actual needs.

[0077] In an exemplary embodiment, Figure 4 As shown, step 302 includes step 402: determining a first disinfection ability parameter of the disinfectant according to the oxidation-reduction potential value and the target oxidation-reduction potential value.

[0078] Among them, the target redox potential value characterizes that the disinfectant can provide sufficient disinfection effect without causing much damage to other devices under the target redox potential value. The disinfection target redox potential value is a preset fixed value, and the specific value can be determined according to the use scenario of the disinfectant. For example, if the disinfectant is used in the inner tank of a dishwasher, the target redox potential value can be any value within 600-800 mV, including the endpoint values ​​600mV and 800mV.

[0079] The method of determining the first disinfection ability parameter of the disinfectant according to the redox potential value and the target redox potential value is not unique. For example, the ratio of the redox potential value to the target redox potential value can be used as the first disinfection ability parameter. The ratio of the redox potential value to the target redox potential value can reflect the degree of difference between the detected redox potential value and the target redox potential value.

[0080] In this embodiment, the first disinfection ability parameter of the disinfectant is determined according to the oxidation-reduction potential value and the target oxidation-reduction potential value, so that the first disinfection ability parameter can reflect the difference between the oxidation-reduction potential value and the target oxidation-reduction potential value.

[0081] In an exemplary embodiment, Figure 5 As shown, step 304 includes step 504: determining a second disinfection capability parameter of the disinfectant according to the preset pH value interval of the pH value.

[0082] Among them, the number of preset pH value intervals can be multiple, and different preset pH value intervals represent different disinfection capabilities of the disinfectant, and different preset pH value intervals can correspond to different second disinfection capability parameters. For example, the second disinfection capability parameter corresponding to the preset pH value interval of 5.5-6.5 with a pH value of 100 points; the second disinfection capability parameter corresponding to the preset pH value interval of 5.0-5.5 with a pH value of 80 points; the second disinfection capability parameter corresponding to the preset pH value interval of 6.5-8 with a pH value of 80 points; the second disinfection capability parameter corresponding to the preset pH value interval with a pH value less than 5.0 or greater than 8.0 with a pH value of 0 points.

[0083] After the pH value of the disinfectant is determined, the second disinfection ability parameter of the disinfectant can be determined according to the preset pH value range in which the pH value is located, and the implementation process is simple.

[0084] In this embodiment, according to the preset pH value range of the pH value, the second disinfection ability parameter of the disinfectant is determined to be the second disinfection ability parameter corresponding to the preset pH value range of the pH value. The corresponding second disinfection ability parameter can be quickly matched, and the matched second disinfection ability parameter can accurately reflect the disinfection ability of the current disinfectant.

[0085] In an exemplary embodiment, Figure 6 As shown, step 306 includes step 606: determining the disinfection capability parameter according to the first disinfection capability parameter and the corresponding first weight value, the second disinfection capability parameter and the corresponding second weight value.

[0086] When determining the disinfection capability parameter according to the first disinfection capability parameter and the second disinfection capability parameter, the first disinfection capability parameter and the second disinfection capability parameter may have different influences on the disinfection capability parameter based on different weights.

[0087] In this step, the weight corresponding to the first disinfection ability parameter is the first weight, and the weight corresponding to the second disinfection ability parameter is the second weight. The first weight value is greater than the second weight value. Thus, the influence of the first disinfection ability parameter on the disinfection ability parameter is greater than the influence of the second disinfection ability parameter on the disinfection ability parameter, and the influence of the redox potential value on the disinfection ability parameter is greater than the influence of the pH value on the disinfection ability parameter. Since the influence of the redox potential value on the disinfection ability of the disinfectant is greater than the influence of the pH value, based on the first disinfection ability parameter and the corresponding first weight value, the second disinfection ability parameter and the corresponding second weight value, when determining the disinfection ability parameter, the determined disinfection ability parameter can more accurately characterize the disinfection ability state of the disinfectant.

[0088] The specific values ​​of the first weight value and the second weight value are not limited. For example, the first weight value may be 0.7 and the second weight value may be 0.3. It is understood that in other embodiments, the first weight value and the second weight value may be other values ​​as long as those skilled in the art consider it achievable.

[0089] In this embodiment, the disinfection ability parameter is determined based on the first disinfection ability parameter and the corresponding larger first weight value, the second disinfection ability parameter and the corresponding smaller second weight value, so that the determined disinfection ability parameter can more accurately characterize the disinfection ability state of the disinfectant.

[0090] In an exemplary embodiment, Figure 7 As shown, step 208 includes step 702 and step 704 .

[0091] Step 702: When the disinfection capability parameter is greater than or equal to the target disinfection capability parameter, the disinfectant preparation machine is controlled to stop working.

[0092] Among them, the target disinfection ability parameter characterizes the disinfection ability of the disinfectant. The type and value of the target disinfection ability parameter are not unique. For example, if the type of the disinfection ability parameter is a fraction, the type of the target disinfection ability parameter can also be a fraction, and the value of the target disinfection ability parameter can be any value between 90 and 100, including the endpoint values ​​of 90 and 100.

[0093] When the disinfection ability parameter is greater than or equal to the target disinfection ability parameter, it means that the disinfection ability of the disinfectant is relatively strong at this time, and the disinfectant preparation machine can be controlled to stop working to save energy consumption.

[0094] Step 704: When the disinfection capability parameter is less than the target disinfection capability parameter, the electrodes of the disinfectant preparation machine are controlled to be energized.

[0095] When the disinfection ability parameter is less than the target disinfection ability parameter, it means that the disinfection ability of the disinfectant is weak at this time. In this case, the electrodes of the disinfectant preparation machine are controlled to be energized, and the disinfectant is continued to be prepared to increase the concentration of the disinfectant, thereby improving the disinfection effect of the disinfectant so that the disinfection effect can meet user needs.

[0096] In this step, when the disinfection capability parameter is greater than or equal to the target disinfection capability parameter, the disinfectant preparation machine is controlled to stop working; when the disinfection capability parameter is less than the target disinfection capability parameter, the electrodes of the disinfectant preparation machine are controlled to be energized. Thus, the disinfectant preparation machine can be controlled to be in a suitable working state according to the magnitude relationship between the disinfection capability parameter and the target disinfection capability parameter, which can not only ensure the disinfection effect of the disinfectant to a certain extent, but also reduce the workload of the disinfectant preparation machine.

[0097] In an exemplary embodiment, Figure 8 As shown, step 704 includes step 802 and step 804 .

[0098] Step 802: When the disinfection capability parameter is less than the target disinfection capability parameter, obtain the liquid level of the disinfectant.

[0099] When the disinfection capability parameter is less than the target disinfection capability parameter, it indicates that there may be no disinfectant or less disinfectant at this time. Therefore, the liquid level of the disinfectant is further obtained at this time, and the amount of the disinfectant is determined according to the liquid level of the disinfectant.

[0100] The liquid level of the disinfectant can be detected by a liquid level detection device and sent to the controller. The liquid level detection device is arranged in the disinfectant preparation machine, specifically in the disinfectant manufacturing box of the disinfectant preparation machine, and further in the disinfectant manufacturing box at a position corresponding to the lower limit of the target liquid level.

[0101] Step 804, when the liquid level is less than or equal to the target liquid level lower limit, after controlling the water inlet pipeline of the disinfectant preparation machine to be conductive, control the electrodes of the disinfectant preparation machine to be energized.

[0102] The controller analyzes the liquid level of the received disinfectant. If it is determined that the liquid level is less than or equal to the target liquid level lower limit, it means that there is no disinfectant at this time, or the amount of disinfectant is very small. In this case, the controller first controls the water inlet pipeline of the disinfectant preparation machine to be turned on, so that the liquid in the disinfectant production tank increases, and then controls the electrodes of the disinfectant preparation machine to be energized to start preparing the disinfectant.

[0103] When the liquid level is greater than the target liquid level lower limit, it means that the amount of disinfectant in the disinfectant manufacturing box is sufficient, but the disinfection ability of the disinfectant may decrease due to long-term non-use or other factors. Therefore, when the liquid level is greater than the target liquid level lower limit, the electrodes of the disinfectant preparation machine can be directly controlled to be energized to prepare the disinfectant to improve the disinfection effect of the disinfectant.

[0104] In this embodiment, when the disinfection capability parameter is less than the target disinfection capability parameter, the liquid level of the disinfectant is obtained, and when the liquid level is less than or equal to the lower limit of the target liquid level, the water inlet pipeline of the disinfectant preparation machine is controlled to be connected, and then the electrodes of the disinfectant preparation machine are controlled to be energized. Thus, the disinfectant preparation machine can be controlled to be in a suitable working state in combination with the liquid level of the disinfectant, thereby improving the working performance of the disinfectant preparation machine.

[0105] In an exemplary embodiment, Fig. 9 As shown, before step 202, the disinfectant preparation machine control method further includes step 901: receiving a disinfection start instruction.

[0106] The disinfection start instruction indicates that the user needs to use disinfectant. The user can send the disinfection start instruction through the interactive device, and the controller can receive a signal from the interactive device to receive the disinfection start instruction. The interactive device can be a touch screen, a button, or a voice device.

[0107] After receiving the disinfection start instruction, the controller indicates that the user has a need to use disinfectant at this time. In this case, step 202 and subsequent steps are executed to control the working state of the disinfectant preparation machine according to the real-time state of the disinfectant, so that the disinfectant preparation machine can produce disinfectant that can meet the user's needs.

[0108] In this embodiment, after receiving the disinfection start instruction, the redox potential value of the disinfectant is obtained, and the detection of the disinfectant can be started when needed to meet the needs of the user; when the user does not need the disinfectant, there is no need to detect the disinfectant, which can save work flow and reduce the workload of the device.

[0109] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0110] Based on the same inventive concept, the embodiment of the present application also provides a disinfectant preparation machine control device for implementing the disinfectant preparation machine control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more disinfectant preparation machine control device embodiments provided below can refer to the limitations of the disinfectant preparation machine control method above, and will not be repeated here.

[0111] In one embodiment, Fig.10 As shown, a control device for a disinfectant preparation machine is provided, comprising: an oxidation-reduction potential value acquisition module 1002, a pH value acquisition module 1004, a disinfection ability determination module 1006 and a disinfection control module 1008, wherein:

[0112] The oxidation-reduction potential value acquisition module 1002 is used to acquire the oxidation-reduction potential value of the disinfectant; the disinfectant is the disinfectant prepared by the disinfectant preparation machine;

[0113] A pH value acquisition module 1004 is used to obtain the pH value of the disinfectant;

[0114] A disinfection capability determination module 1006, configured to determine the disinfection capability parameter of the disinfectant according to the oxidation-reduction potential value and the pH value;

[0115] The disinfection control module 1008 is used to control the working state of the disinfectant preparation machine according to the disinfection ability parameter.

[0116] In an exemplary embodiment, the disinfection ability determination module is also used to determine a first disinfection ability parameter of the disinfectant according to the redox potential value; determine a second disinfection ability parameter of the disinfectant according to the pH value; and determine a disinfection ability parameter according to the first disinfection ability parameter and the second disinfection ability parameter.

[0117] In an exemplary embodiment, the disinfection ability determination module is further used to determine a first disinfection ability parameter of the disinfectant according to the oxidation-reduction potential value and the target oxidation-reduction potential value.

[0118] In an exemplary embodiment, the disinfection ability determination module is further used to determine a second disinfection ability parameter of the disinfectant according to a preset pH value interval in which the pH value is located.

[0119] In an exemplary embodiment, the disinfection capability determination module is also used to determine the disinfection capability parameter based on the first disinfection capability parameter and the corresponding first weight value, the second disinfection capability parameter and the corresponding second weight value; the first weight value is greater than the second weight value.

[0120] In an exemplary embodiment, the disinfection control module is also used to control the disinfectant preparation machine to stop working when the disinfection ability parameter is greater than or equal to the target disinfection ability parameter; when the disinfection ability parameter is less than the target disinfection ability parameter, control the electrodes of the disinfectant preparation machine to be energized.

[0121] In an exemplary embodiment, the disinfection control module is also used to obtain the liquid level of the disinfectant when the disinfection capacity parameter is less than the target disinfection capacity parameter; when the liquid level is less than or equal to the target liquid level lower limit, the water inlet pipeline of the disinfectant preparation machine is controlled to be conductive, and then the electrodes of the disinfectant preparation machine are controlled to be energized.

[0122] In an exemplary embodiment, the disinfectant preparation machine control device further includes an instruction receiving module, which is used to receive a disinfection start instruction before the oxidation-reduction potential value acquisition module acquires the oxidation-reduction potential value of the disinfectant.

[0123] Each module in the above disinfectant preparation machine control device can be implemented in whole or in part by software, hardware and a combination thereof. Each module can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute operations corresponding to each module above.

[0124] In one embodiment, a disinfectant preparation machine control device is provided, including an oxidation-reduction potential detection device, an acid-base detection device and a controller. The oxidation-reduction potential detection device and the acid-base detection device are both arranged in the disinfectant preparation machine and are both connected to the controller. The controller is used to connect to the disinfectant preparation machine; the oxidation-reduction potential detection device is used to detect the oxidation-reduction potential value of the disinfectant and send it to the controller, the acid-base detection device is used to detect the acid-base value of the disinfectant and send it to the controller, and the controller is used to control the disinfectant preparation machine according to the method of any of the above embodiments.

[0125] The oxidation-reduction potential detection device can be arranged in the disinfectant manufacturing box of the disinfectant preparation machine to detect the oxidation-reduction potential value of the liquid in the disinfectant manufacturing box. The oxidation-reduction potential detection device is also connected to the controller for data exchange with the controller.

[0126] The number of oxidation-reduction potential detection devices is not unique. For example, the number of oxidation-reduction potential devices can be more than two, and different oxidation-reduction potential detection devices are arranged at different positions, and are used to detect the oxidation-reduction potential value of the disinfectant at different positions and send it to the controller. The controller can analyze each received oxidation-reduction potential value to obtain the final detection result of the oxidation-reduction potential value. For example, the controller uses the average value of each received oxidation-reduction potential value as the final detection result of the oxidation-reduction potential value. By setting a plurality of oxidation-reduction potential detection devices, the accuracy of the detected oxidation-reduction potential value can be improved. It can be understood that in other embodiments, the number of oxidation-reduction potential detection devices can also be one to save hardware resources.

[0127] The type of redox potential detection device is also not limited, for example, it can be an ORP (Oxidation-Reduction Potential) meter. ORP determines the ORP value by measuring the potential difference of the redox pair in the solution. The ORP meter usually consists of a reference electrode and a working electrode, which are placed in the solution to be tested. The working electrode is a sensitive electrode that reacts with the oxidant and reductant in the solution, while the reference electrode provides a stable reference potential. By measuring the potential difference between the two electrodes, the ORP meter can calculate the redox potential of the solution.

[0128] The oxidation-reduction potential detection device can detect the oxidation-reduction potential value in real time, and the controller can also receive the oxidation-reduction potential value from the oxidation-reduction potential detection device in real time, so as to continuously monitor the oxidation-reduction potential value of the disinfectant, which is more conducive to improving the quality of the disinfectant. Alternatively, in other embodiments, the oxidation-reduction potential detection device can also detect the oxidation-reduction potential value at a certain time interval, and the controller can also receive the oxidation-reduction potential value from the oxidation-reduction potential detection device at a certain time interval, so as to reduce the amount of interactive data and reduce the workload of the device.

[0129] The acid-base detection device can be arranged in the disinfectant manufacturing box of the disinfectant preparation machine to detect the acid-base value of the liquid in the disinfectant manufacturing box. The acid-base detection device is also connected to the controller for data exchange with the controller.

[0130] The number of acid-base detection devices is not unique. For example, the number of acid-base detection devices can be more than two, and different acid-base detection devices are set at different positions to detect the pH value of the disinfectant at different positions and send it to the controller. The controller can analyze the received pH values ​​to obtain the final pH value detection result. For example, the controller uses the average value of the received pH values ​​as the final pH value detection result. The accuracy of the detected pH value can be improved by setting multiple acid-base detection devices. It can be understood that in other embodiments, the number of acid-base detection devices can also be one to save hardware resources.

[0131] There are also different types of acid-base detection devices. For example, the acid-base detection device can be a pH meter. The pH meter measures the pH value of a solution by potentiometric method. The pH meter mainly consists of two parts: an electrode and an electric meter. Its working principle is to measure the pH value of a solution by potentiometric method based on a pH indicator electrode. Specifically, a pH indicator electrode (usually a glass electrode and a reference electrode) is inserted into the solution to be tested to form a galvanic cell, and the pH value of the solution is calculated by measuring the change in electrode potential.

[0132] The acid-base detection device can detect the acid-base value in real time, and the controller can also receive the acid-base value from the acid-base detection device in real time, so as to continuously monitor the acid-base value of the disinfectant, which is more conducive to improving the quality of the disinfectant. Alternatively, in other embodiments, the acid-base detection device can also detect the acid-base value at a certain time interval, and the controller can also receive the acid-base value from the acid-base detection device at a certain time interval, so as to reduce the amount of interactive data and reduce the workload of the device.

[0133] The controller obtains the redox potential value and pH value of the disinfectant prepared by the disinfectant preparation machine, determines the disinfection ability parameter of the disinfectant according to the redox potential value and the pH value, and controls the working state of the disinfectant preparation machine according to the disinfection ability parameter. The disinfection ability of the disinfectant can be effectively and timely judged by the redox potential value and the pH value, and the working state of the disinfectant preparation machine can be controlled according to the test results, which can improve the performance of the disinfectant prepared by the disinfectant preparation machine, not only improve the disinfection effect, but also reduce the harmfulness of the disinfectant, thereby improving the reliability of the use of the disinfectant.

[0134] In one embodiment, Fig.11 As shown, a dishwasher is provided, including a dishwasher inner tank, a disinfectant preparation machine and a disinfectant preparation machine control device as in the above embodiment.

[0135] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. Fig.11As shown, the dishwasher includes a dishwasher tank, a disinfectant preparation machine and a disinfectant preparation machine control device as in the above embodiment. The disinfectant preparation machine control device includes an oxidation-reduction potential detection device, an acid-base detection device and a controller, the oxidation-reduction potential detection device is an ORP meter, and the acid-base detection device is a pH meter. Both the ORP meter and the pH meter are placed in the disinfectant for measurement.

[0136] Let the target redox potential value be A, the measured OPR value be An, the target pH value be B, the measured pH value be Bn, the target disinfection ability parameter be score S, and the disinfection ability parameter be score Sn. The first weight value is 0.7, and the second weight value is 0.3. The score within the pH range is determined as follows: 100 points for a pH value within 5.5-6.5, 80 points for a pH value within 5.0-5.5 or 6.5-8, and 0 points for a pH value less than 5.0 or greater than 8.0.

[0137] Generally speaking, the ORP value of disinfectant can reach 600-1000 mV, or even higher. The following are some specific data ranges: low-concentration disinfectant: ORP value is about 600-800 mV; medium-concentration disinfectant: ORP value is about 800-1000 mV; high-concentration disinfectant: ORP value can reach 1000-1200 mV. When using disinfectant in a dishwasher, the recommended target ORP value range is 600-800 mV, and the optimal value is 700-750 mV. This range can provide sufficient disinfection effect without causing damage to the materials and tableware of the dishwasher. You can take the average of multiple groups of data tested in multiple areas. When the test ORP value is 750mV, measure the pH value of the disinfectant, which is 100 points as the optimal value. If the pH value is too low or too high, the score will gradually decrease.

[0138] When there is no disinfectant in the disinfectant manufacturing box, it is necessary to add clean water and start preparation again. There is disinfectant in the disinfectant manufacturing box, but if it has not been used for a long time, its disinfection ability may decrease, and plasma needs to be replenished.

[0139] like Fig.12 As shown, after the dishwasher enters the disinfectant preparation stage, the ORP meter and the pH meter begin to detect and record the current ORP value A1 and the pH value B1 of the disinfectant water, calculate the current disinfectant score S1 based on the current A1 and B1, and determine the relationship between S1 and the target score S. When the target score is met, the disinfectant preparation is completed and the preparation of the disinfectant is stopped. When the disinfectant does not meet the target score, the electrodes are energized and the preparation of the disinfectant begins. At the same time, the ORP meter and the pH meter are detected in real time. When the calculation meets the S score, the preparation of the disinfectant is stopped.

[0140] The following are test data sets for several disinfectants used for dishwasher disinfection:

[0141] After setting the target OPR value to 800 mV, on day 0, the measured ORP value was 800 mV and the measured pH value was 5.5.

[0142] ORP value score = ; pH value score = ; Total score = 70 + 30 = 100.

[0143] On day 1, the measured ORP value was 750 mV and the measured pH value was 6.0. ORP value score = ; pH value score = ; Total score = 65.6 + 30 = 95.6. And so on, in summary, as time goes by, the disinfectant scores lower and the disinfection properties worse.

[0144] This application determines the preparation degree of the disinfectant by testing the oxidation-reduction potential (ORP) value and pH value of the disinfectant water in the disinfectant manufacturing box. These two indicators can effectively and timely determine whether the disinfection ability of the disinfectant meets the standard. The test results are used to control the working state of the electrode, so that the characteristics of the disinfectant prepared each time can be made consistent as much as possible, and the disinfection characteristics are strictly controlled, so as not to cause harm to the human body, equipment, tableware, etc.
