[0002] With the continuous improvement of people's living standards, dishwashers and other equipment have entered people's daily life. In order to improve the cleaning effect of tableware, dishwashers usually use plasma sterilization technology to sterilize tableware. This technology uses a glow discharge device to discharge, and the discharge process generates plasma. The interaction between active substances in the plasma and water molecules can significantly change the chemical and physical properties of water, resulting in disinfectant. The disinfectant can destroy the cell membrane and DNA of microorganisms, has good sterilization and disinfection effect, and can achieve sterilization and disinfection of tableware.

[0003] The disinfectant preparation apparatus in the existing dishwasher usually makes the glow discharge device continuously discharge at full power to ensure the efficiency of plasma generation. However, when the glow discharge device operates at full power, it will cause strong electromagnetic interference to other components in the dishwasher, resulting in low reliability of the dishwasher.

[0067] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0068] An embodiment of the present application provides a disinfectant preparation device, as shown in the drawings, the disinfectant preparation device comprises a water inlet pipeline, a water inlet component, a water storage device and a glow discharge device arranged in the water storage device. The water inlet pipeline is connected to the water storage device, and the water inlet pipeline serves as a conveying passage for water inlet and is also connected to an external water source (such as a tap water pipeline, a water tank or the like). Figure 1

[0069] The water inlet component is arranged in the water inlet pipeline and is used to drive water flow through the water inlet pipeline into the water storage device. Specifically, the water storage device can adopt a water tank, and the water inlet component can adopt a power device such as a water pump. In actual application, when the water inlet component (the water pump starts to work) is started, a certain pressure is generated, which promotes the water in the external water source to flow into the water storage device along the water inlet pipeline, thereby providing a basic water amount for subsequent disinfectant preparation.

[0070] The top or side of the water storage device is provided with a water inlet connected to the water inlet pipeline, and the bottom or side can also be provided with a water outlet for discharging the prepared disinfectant. As an example, the disinfectant preparation device is used in a dishwasher, the dishwasher comprises a disinfection cavity for accommodating a utensil to be disinfected, the water outlet of the water storage device is connected to the disinfection cavity through a water discharge pipeline, and when disinfection is needed, a water discharge pump is started to quickly discharge the disinfectant to the disinfection cavity.

[0071] The glow discharge device comprises a gas passage, a gas supply component, a plurality of discharge electrodes and a plurality of discharge cavities, the discharge cavities are arranged in the water storage device, and the discharge electrodes are arranged in the discharge cavities; the discharge cavities are connected to the water storage device and the gas passage, and the gas supply component is arranged in the gas passage and is used to drive the gas in the gas passage to circulate.

[0072] ​The discharge cavities are arranged perpendicularly to the bottom of the water storage device (e.g., a water tank) and are concentrated in the middle of the water storage device. The discharge cavities can be made of glass and have a tubular installation space, which is the area for glow discharge. The bottom or other positions (e.g., sidewalls) of the tubular installation space are provided with fine holes. At least one discharge electrode is arranged in each tubular installation space. The discharge electrodes can perform glow discharge. The ionized plasma active substances enter the water in the water storage device through the fine holes and interact with the water molecules, so that ordinary water is changed into sterilization liquid. The specific number and arrangement of the discharge cavities can be set according to actual conditions. In this embodiment, the discharge cavities can be arranged in two rows (only the front row is shown in the figure), and one discharge electrode is arranged in each tubular installation space. In actual application, one or several discharge electrodes or one or two rows of discharge electrodes can be selected for discharge. Figure 1

[0073] As an example, a gas channel is arranged on the upper part of the water storage device, and each discharge cavity is connected to the inside of the water storage device and the gas channel. Specifically, the top of the discharge cavity is connected to the gas channel, and the bottom is connected to the liquid in the inside of the water storage device. A gas supply member is arranged in the gas channel and drives the circulation of the gas in the gas channel. The circulation direction of the gas in the gas channel is indicated by arrows. The gas supply member can blow gas downward from top to bottom to the tubular discharge cavity where the electrode is arranged, so that the tubular discharge cavity remains dry, and at the same time, the ionized plasma active substances generated by the electrode can be blown into the water in the water storage device through the fine holes to achieve the preparation of sterilization liquid. As an example, the gas supply member can be a gas pump or the like.

[0074] The sterilization liquid preparation device further includes a control system. The water inlet member, the gas supply member, and each discharge electrode are electrically connected to the control system. It can be understood that the sterilization liquid preparation device further includes a water quality detection assembly electrically connected to the control system, which is used to detect the water quality parameters of the liquid in the water storage device in real time and transmit them to the control system. The control system is used to execute the sterilization liquid preparation method.

[0075] In some embodiments, the water quality detection assembly includes a conductivity sensor electrically connected to the control system. The conductivity sensor is located on the inner wall of the water storage device and is used to detect the conductivity of the liquid in the water storage device.

[0076] In some embodiments, the water quality detection assembly includes a pH meter. The detection rod of the pH meter is located in the water storage device and is used to sample the pH data of the liquid in the water storage device in real time. The calculation unit of the pH meter is located outside the water storage device and is used to obtain the pH value (i.e., the acidity or alkalinity) of the liquid according to the data transmitted by the detection rod and transmit it to the control system.

[0077] When the sterilization liquid preparation device is used for a dishwasher, the control system can be a separate controller or can use the original controller of the dishwasher. The specific design can be made according to actual conditions.​

[0078] The disinfectant solution preparation device can dynamically adjust the number of operating discharge electrodes and the discharge power of the glow discharge device according to the liquid water quality parameter in the water storage device during preparation of the disinfectant solution, thereby reducing the intensity and duration of high-voltage discharge, weakening electromagnetic interference on other components, and improving the overall use reliability of the device. Moreover, the design of the two rows of discharge electrodes effectively increases the number of electrodes that can discharge at the same time, which can reduce the voltage during discharge of each electrode and reduce electromagnetic interference, and can improve the disinfectant solution preparation efficiency.

[0079] The disinfectant solution preparation method provided by the embodiments of the present application can be applied to a disinfectant solution preparation device. In an exemplary embodiment, the method is applied to the control system of the disinfectant solution preparation device, as shown in Figure 2 The disinfectant solution preparation method includes the following steps 202 to 206. Among them:

[0080] Step 202: In response to a disinfectant solution preparation self-adjustment instruction, the initial water quality parameter of the liquid in the water storage device is obtained.

[0081] The disinfectant solution preparation self-adjustment instruction can be issued by the user or generated by the control system. As an example, the control system generates the disinfectant solution preparation self-adjustment instruction when the operating state of the glow discharge device reaches a steady state. In the case where the disinfectant solution preparation self-adjustment instruction is not received, the control system can control each discharge electrode in the glow discharge device to operate at an initial power.

[0082] When the disinfectant solution preparation self-adjustment instruction is received, the control system immediately obtains the liquid water quality parameter in the water storage device through the water quality detection assembly as the initial water quality parameter.

[0083] Step 204: Determine the operating state and operating power of each discharge electrode based on the initial water quality parameter.

[0084] The operating state includes operation and stop operation. It can be understood that the control system can control each discharge electrode to operate or stop operation based on the initial water quality parameter, and the operating power of the operating discharge electrode.

[0085] As an example, the initial water quality parameter includes an initial pH value. When the initial pH value is high, the control system controls the discharge electrode to discharge at a higher operating power to enhance the intensity of the glow discharge, thereby generating more active particles to improve the water quality.

[0086] The control system is internally provided with a timer for recording the discharge duration of the discharge electrode. When the control system controls the operation or stop of operation of each discharge electrode based on the initial water quality parameter, since at least part of the discharge electrodes are operating discharge at this time, the timer starts timing from the current time, and the recorded duration is taken as the discharge duration of the discharge electrode.

[0087] Step 206, in the case where the discharge duration of the discharge electrode reaches the preset interval detection duration, the current water quality parameter of the liquid in the water storage device is obtained, and the operation state and operation power of the discharge electrode are adjusted based on the current water quality parameter and the initial water quality parameter.

[0088] The size of the preset interval detection duration can be set according to actual conditions, for example, 5 minutes, for example, 10 minutes, or other durations.

[0089] When the discharge duration of the discharge electrode reaches the preset interval detection duration, the control system again obtains the current water quality parameter of the liquid in the water storage device through the water quality detection assembly. Then the control system compares and analyzes the current water quality parameter with the initial water quality parameter to determine whether the water quality change of the current liquid meets the expectation, so as to adjust the number and operation power of the operating discharge electrode in combination with the water quality change.

[0090] Step 208, updating the initial water quality parameter according to the current water quality parameter, and returning to obtaining the current water quality parameter of the liquid in the water storage device in the case where the discharge duration of the discharge electrode reaches the preset interval detection duration.

[0091] After completing the adjustment of the operation state and operation power of the discharge electrode based on the current water quality parameter and the initial water quality parameter, the control system will also set the current water quality parameter as the initial water quality parameter, and complete the update of the initial water quality parameter. Thus, the subsequent detection and adjustment can be based on the latest water quality, and the actual state and change trend of the liquid can be more accurately reflected.

[0092] After updating the initial water quality parameter, the control system will also re-time the discharge duration, and return to step 206 to continue waiting for the discharge duration of the discharge electrode to reach the preset interval detection duration. Once the duration is reached, the control system again repeats the operation of step 206 to obtain a new current water quality parameter, and compares and analyzes the new initial water quality parameter (i.e. the current water quality parameter after the last update) and the new current water quality parameter, and further adjusts the operation state and operation power of the discharge electrode, forming a dynamic and cyclic adjustment process, to ensure that the water quality in the disinfectant preparation process is always in a state matching the current water quality and preparation state.

[0093] Step 210, in the case where the state of the disinfectant preparation equipment reaches the disinfectant preparation end condition, the operation state of each discharge electrode is adjusted to stop operation.

[0094] During the operation of the discharge electrodes, the control system monitors the state of the disinfectant solution preparation device in real time. When it is detected that the state of the device meets the preset disinfectant solution preparation end condition, the control system sends a control signal to stop operation to all discharge electrode driving circuits, so that each discharge electrode stops operation, thereby ending the disinfectant solution preparation process.

[0095] The determination of the state of the disinfectant solution preparation device reaching the disinfectant solution preparation end condition can be flexibly configured according to actual needs. In some embodiments, the total operation time length of the glow discharge device in the disinfectant solution preparation device in the current disinfectant solution preparation process can be determined, for example, when the total operation time length of the glow discharge device reaches the preset disinfectant solution preparation time, it is determined that the disinfectant solution preparation end condition is reached. In other embodiments, the control system also acquires the water quality parameter of the liquid in the water outlet device of the disinfectant solution preparation device in real time through the water quality detection assembly. When the water quality parameter matches the disinfectant solution target parameter, it is determined that the disinfectant solution preparation end condition is reached. The disinfectant solution target parameter is the water quality parameter of the liquid that meets the disinfection requirement. The water quality parameter matches the disinfectant solution target parameter, that is, the difference between the water quality parameter and the disinfectant solution target parameter is within the allowable range.

[0096] The above disinfectant solution preparation method, in response to the disinfectant solution preparation self-adjusting instruction, acquires the initial water quality parameter of the liquid in the water storage device; determines the operation state and operation power of each discharge electrode based on the initial water quality parameter, the operation state including operation and stop operation; in the case that the discharge time length of the discharge electrode reaches the preset interval detection time length, acquires the current water quality parameter of the liquid in the water storage device, and adjusts the operation state and operation power of the discharge electrode based on the current water quality parameter and the initial water quality parameter; updates the initial water quality parameter according to the current water quality parameter, and returns to the case that the discharge time length of the discharge electrode reaches the preset interval detection time length, acquires the current water quality parameter of the liquid in the water storage device; in the case that the state of the disinfectant solution preparation device reaches the disinfectant solution preparation end condition, adjusts the operation state of each discharge electrode to stop operation. Thus, during the preparation of disinfectant solution by the disinfectant solution preparation device, the electrode operation state and discharge power of the glow discharge device can be dynamically adjusted according to the water quality parameter in the water storage device, thereby reducing the intensity and duration of high-voltage discharge, weakening the electromagnetic interference on other components, improving the safety of the glow discharge device, and improving the overall use reliability of the device.

[0097] In some embodiments, as shown in Figure 3 The step of determining the operation state and operation power of each discharge electrode based on the initial water quality parameter includes steps 302 and 304.

[0098] Step 302, in the case that the initial water quality parameter meets the first water quality requirement, a first number of discharge electrodes are controlled to operate, and the operating power of each of the operating discharge electrodes is a first operating power.

[0099] Specifically, when the control system obtains the initial water quality parameter in the water storage device, it compares it with the pre-set first water quality requirement. If it is determined that the initial water quality parameter meets the first water quality requirement, it can be determined that the current liquid is far from the expected disinfectant target parameter, and more energy input and more sufficient reaction process are needed to reach the target. At this time, the control system will control the first number of discharge electrodes to start operating according to the pre-set corresponding relationship. The first number can be obtained through a large number of experiments or simulation optimization, for example, in a device with 10 discharge electrodes, the first number can be 10 or 8, etc.

[0100] At the same time, the control system will also set the operating power of these operating discharge electrodes to be the first operating power. The first operating power is a relatively high power value, which can generate a sufficient number and intensity of active particles, which can fully react with the components in the liquid, gradually improve the water quality, and make it close to the disinfectant target parameter.

[0101] Step 304, in the case that the initial water quality parameter meets the second water quality requirement, a second number of discharge electrodes are controlled to operate, and the operating power of each of the operating discharge electrodes is a second operating power.

[0102] Wherein, the closeness between the initial water quality parameter meeting the second water quality requirement and the disinfectant target parameter is greater than the closeness between the initial water quality parameter meeting the first water quality requirement and the disinfectant target parameter; the second number is less than the first number; and the second operating power is less than the first operating power.

[0103] If the control system determines that the initial water quality parameter meets the second water quality requirement, it can be determined that the current liquid is closer to the expected disinfectant target parameter, and does not need too much energy input and too intense reaction process. At this time, the control system will control the second number of discharge electrodes to start operating according to the pre-set corresponding relationship. The second number will be less than the first number, for example, in the above-mentioned device with 10 discharge electrodes, the second number can be set to 5 or 4, etc. At the same time, the control system will set the operating power of these operating discharge electrodes to be the second operating power. The second operating power is a relatively low power value, because in the case that the initial water quality is close to the target, a lower power can generate an appropriate amount of active particles, which can meet the needs of disinfectant preparation, and can avoid problems such as electromagnetic interference and energy waste caused by too high power. Exemplarily, the first operating power is the maximum operating power of the discharge electrode, and the second operating power is half of the maximum operating power.

[0104] In some embodiments, the first number is the total number of discharge electrodes in the glow discharge device. By setting the first number as the total number of discharge electrodes in the glow discharge device, the full discharge capacity of the glow discharge device can be fully utilized to generate a sufficient number and intensity of active particles, thereby improving the preparation rate. Moreover, all the discharge electrodes are arranged in two rows opposite to each other, so that the active particles generated in the discharge process can be more uniformly diffused into the liquid and fully contact and react with the liquid.

[0105] In some embodiments, the second number is half of the first number, i.e., one-half. When the number of discharge electrodes operating at the same time is the second number, the workload of the electrodes can be reduced, which helps to reduce electromagnetic interference. In actual implementation, when the discharge electrodes operating at the second number, the discharge electrodes in the same row of discharge cavities can be controlled to operate.

[0106] In the present embodiment, the number and power of the discharge electrodes operating are flexibly controlled according to the initial water quality parameters, which can more accurately adapt to the disinfectant preparation requirements under different initial water quality conditions, reduce electromagnetic interference, and improve energy utilization efficiency while ensuring the quality of the disinfectant.

[0107] In some embodiments, the step of adjusting the operating state and operating power of each discharge electrode based on the current water quality parameters and the initial water quality parameters comprises the following steps:

[0108] determining a water quality change parameter based on the current water quality parameters and the initial water quality parameters;

[0109] when the water quality change parameter meets a first water quality adjustment condition, controlling the second number of discharge electrodes to operate, and the operating power of each discharge electrode operating is the second operating power;

[0110] when the water quality change parameter meets a second water quality adjustment condition, controlling the first number of discharge electrodes to operate, and the operating power of each discharge electrode operating is the second operating power;

[0111] when the water quality change parameter meets a third water quality adjustment condition, controlling the first number of discharge electrodes to operate, and the operating power of each discharge electrode operating is the first operating power.

[0112] wherein the water quality change degree represented by the water quality change parameter when the second water quality adjustment condition is met is less than the water quality change degree represented by the water quality change parameter when the first water quality adjustment condition is met, and greater than the water quality change degree represented by the water quality change parameter when the third water quality adjustment condition is met.

[0113] In this embodiment, the control system obtains the water quality parameter at the current time as the current water quality parameter through the water quality detection assembly when the discharge duration reaches the preset interval detection duration. Then, the control system comprehensively analyzes and processes the current water quality parameter and the initial water quality parameter to calculate a water quality change parameter that can reflect the change of the water quality from the previous adjustment of the running state and power of the discharge electrode to the current time.

[0114] When the water quality change parameter meets the first water quality adjustment condition, it indicates that the water quality has changed significantly, exceeding the expected discharge requirement. At this time, the control system will issue a control instruction to control the second number of discharge electrodes to operate. And in order to effectively respond to this large degree of water quality change, the control system will uniformly set the operating power of each operating discharge electrode to the second operating power, ensuring that the discharge electrode can output appropriate power to process the water quality while reducing electromagnetic interference and improving the safety of the glow discharge device.

[0115] When the water quality change parameter meets the second water quality adjustment condition, since the water quality change degree represented by the water quality change parameter when the second water quality adjustment condition is met is less than the water quality change degree represented by the water quality change parameter when the first water quality adjustment condition is met, it indicates that the water quality change is relatively lower than the first case, but can meet the expected discharge requirement. In this case, the control system controls the first number of discharge electrodes to operate, and the operating power of each operating discharge electrode is also set to the second operating power. In this way, by increasing the number of operating discharge electrodes, the disinfectant solution preparation process can be accelerated.

[0116] When the water quality change parameter meets the third water quality adjustment condition, it indicates that the water quality change in this period of time is relatively small and does not meet the expected discharge requirement. At this time, the control system controls the first number of discharge electrodes to operate, and adjusts the operating power of each operating discharge electrode to the first operating power to accelerate the disinfectant solution preparation process.

[0117] In this embodiment, according to the degree of change of the water quality in the preset interval detection duration, the operating power and the number of the discharge electrodes are adjusted to improve the safety of the disinfectant solution preparation equipment.

[0118] In some embodiments, the initial water quality parameter includes an initial pH value and an initial conductivity. The disinfectant solution preparation method further includes the following steps:

[0119] In the case where the initial pH value reaches the preset pH threshold value and the initial conductivity is less than or equal to the preset conductivity threshold value, it is determined that the initial water quality parameter meets the first water quality requirement;

[0120] In the case where the initial pH value is less than the preset pH threshold value and the initial conductivity is greater than the preset conductivity threshold value, it is determined that the initial water quality parameter meets the second water quality requirement.

[0121] The preset pH threshold and the preset conductivity threshold can be the pH value and the conductivity value of the commonly used tap water, and can be obtained by experiments or set according to experience. The present embodiment does not limit this.

[0122] When the initial pH is greater than or equal to the preset pH threshold, it indicates that the pH of the water quality is in a relatively suitable range for the preparation of the disinfectant solution. At the same time, the initial conductivity is less than or equal to the preset conductivity threshold, which indicates that the water quality is relatively pure because the water contains relatively few conductive ions and other impurities. However, in this case, the gap between the water quality and the target parameters of the disinfectant solution is large, and therefore the control system determines that the initial water quality parameters meet the first water quality requirement. Then, the control system controls the first number of discharge electrodes to operate, and sets the operating power of each operating discharge electrode as the first operating power. Because the higher number of electrodes and the operating power can provide stronger processing capacity to facilitate the water quality to change to the target parameters of the disinfectant solution more quickly.

[0123] When the initial pH is less than the preset pH threshold, it indicates that the water quality is strongly acidic, and the initial conductivity is greater than the preset conductivity threshold, which indicates that the water contains many conductive ions and other impurities. In this case, the water quality is closer to the target parameters of the disinfectant solution. In this case, the control system determines that the initial water quality parameters meet the second water quality requirement. Then, the control system controls the second number of discharge electrodes to operate, and the operating power of each operating discharge electrode is the second operating power. Because the water quality meeting the second water quality requirement is closer to the target parameters of the disinfectant solution, the second number is less than the first number, and the second operating power is less than the first operating power, which can not only ensure the moderate adjustment of the water quality, but also improve the safety of the glow discharge device.

[0124] Therefore, the parameters of the disinfectant preparation device are determined according to the local water quality (for example, the water quality in the user's home), which takes into account the preparation efficiency and helps to improve the safety of the disinfectant preparation device.

[0125] Further, the current water quality parameters include a current pH and a current conductivity. The water quality change parameters include a pH change parameter determined based on the current pH and the initial pH, and a conductivity change parameter determined based on the current conductivity and the initial conductivity. The disinfectant preparation method further includes the following steps:

[0126] In the case that the pH change parameter reaches a first pH change threshold and the conductivity change parameter reaches a first conductivity change threshold, it is determined that the water quality change parameters meet the first water quality adjustment condition.

[0127] In a case where the pH variation parameter is less than the first pH variation threshold and greater than or equal to the second pH variation threshold, and the conductivity variation parameter is less than the first conductivity variation threshold and greater than or equal to the second conductivity variation threshold, it is determined that the water quality variation parameter satisfies the second water quality adjustment condition.

[0128] In a case where the pH variation parameter is less than the second pH variation threshold and the conductivity variation parameter is less than the second conductivity variation threshold, it is determined that the water quality variation parameter satisfies the third water quality adjustment condition.

[0129] The pH variation parameter can be a variation amount or a variation rate. For example, the pH variation parameter is a difference between a current pH and an initial pH, and the conductivity variation parameter is a difference between a current conductivity and an initial conductivity.

[0130] The second pH variation threshold is less than the first pH variation threshold, and the second conductivity variation threshold is less than the first conductivity variation threshold. For example, the first pH variation threshold is twice the second pH variation threshold, and the first conductivity variation threshold is twice the second conductivity variation threshold.

[0131] It can be understood that active substances such as hydroxyl radicals (·OH), superoxide anion radicals (O2·-), ozone (O3), nitric oxide (NO), and nitrogen dioxide (NO2) are continuously generated during the high-voltage discharge process of the discharge electrode, the ion concentration (such as nitrate ions NO3-) of the disinfectant solution gradually increases, and the conductivity changes. Moreover, the active substances can react with water to generate acidic or basic substances, resulting in a change in the pH value of the water. Moreover, when the discharge electrode is discharging, the conductivity and the pH value change in a unidirectional manner, i.e., continuously increasing or continuously decreasing, and do not appear to increase after decreasing or decrease after increasing.

[0132] In the embodiment, the control system determines the water quality adjustment condition according to the pH value and the conductivity variation. When the first water quality adjustment condition is met, it indicates that the water quality changes greatly in the previous preset interval detection duration, and the control system controls a small number of discharge electrodes to operate, and sets the operating power of each operating discharge electrode to the second operating power. When the second water quality adjustment condition is met, it indicates that the water quality changes relatively small in the previous preset interval detection duration, and the control system controls a large number of discharge electrodes to operate, and sets the operating power of each operating discharge electrode to the second operating power. In this way, the preparation efficiency is improved, and the safety of the disinfectant preparation equipment is ensured. When the third water quality adjustment condition is met, it indicates that the water quality changes very small in the previous preset interval detection duration, and the control system controls a large number of discharge electrodes to operate, and sets the operating power of each operating discharge electrode to the first operating power. In this way, the generation and reaction of active substances are accelerated by more electrodes and higher power, so that the water quality changes faster to meet the requirements of disinfectant.

[0133] In actual implementation, the initial water quality parameter can include an initial pH value or an initial conductivity. In some embodiments, the initial water quality parameter includes an initial pH value. The disinfectant preparation method further includes the following steps:

[0134] In the case where the initial pH value reaches a preset pH threshold, it is determined that the initial water quality parameter meets the first water quality requirement; in the case where the initial pH value is less than the preset pH threshold, it is determined that the initial water quality parameter meets the second water quality requirement.

[0135] Further, the current water quality parameter includes a current pH value, and the water quality variation parameter includes a pH variation parameter determined based on the current pH value and the initial pH value. The disinfectant preparation method further includes the following steps:

[0136] In the case where the pH variation parameter reaches a first pH variation threshold, it is determined that the water quality variation parameter meets the first water quality adjustment condition; in the case where the pH variation parameter is less than the first pH variation threshold and greater than or equal to a second pH variation threshold, it is determined that the water quality variation parameter meets the second water quality adjustment condition; in the case where the pH variation parameter is less than the second pH variation threshold, it is determined that the water quality variation parameter meets the third water quality adjustment condition. The second pH variation threshold is less than the first pH variation threshold.

[0137] In the embodiment, the operating number and power of the discharge electrode are adjusted based on the initial pH value and the pH variation parameter, which is simple in implementation and has strong universality.

[0138] In some embodiments, the initial water quality parameter includes an initial conductivity. The disinfectant preparation method further includes the following steps:

[0139] In a case where the initial conductivity is less than or equal to a preset conductivity threshold, it is determined that the initial water quality parameter meets a first water quality requirement; in a case where the initial conductivity is greater than the preset conductivity threshold, it is determined that the initial water quality parameter meets a second water quality requirement.

[0140] Further, the current water quality parameter includes a current conductivity; and the water quality change parameter includes a conductivity change parameter determined based on the current conductivity and the initial conductivity. The disinfectant preparation method further includes the following steps:

[0141] In a case where the conductivity change parameter reaches a first conductivity change threshold, it is determined that the water quality change parameter meets a first water quality adjustment condition; in a case where the conductivity change parameter is less than the first conductivity change threshold and greater than or equal to a second conductivity change threshold, it is determined that the water quality change parameter meets a second water quality adjustment condition; the second conductivity change threshold is less than the first conductivity change threshold; in a case where the conductivity change parameter is less than the second conductivity change threshold, it is determined that the water quality change parameter meets a third water quality adjustment condition.

[0142] In the embodiment, the running number and power of the discharge electrode are adjusted based on the initial conductivity and the conductivity change parameter, the implementation is simple, and the universality is strong.

[0143] In some embodiments, as shown in FIG. 2, step 210 includes steps 402 and 404. Figure 4

[0144] Step 402: In a case where the state of the disinfectant preparation device reaches a disinfectant preparation end condition, a current water quality parameter of the liquid in the water storage device is acquired.

[0145] Step 404: In a case where it is determined that the current water quality parameter matches the disinfectant target parameter, the running state of each discharge electrode is adjusted to stop running.

[0146] When the state of the disinfectant preparation device reaches a preset disinfectant preparation end condition, the control system will immediately acquire the current water quality parameter of the liquid in the water storage device, and perform matching analysis on the current water quality parameter and the pre-set disinfectant target parameter to determine whether the liquid meets the disinfection requirement. If the current water quality parameter matches the disinfectant target parameter, it is determined that the liquid in the water storage device can be used as disinfectant. At this time, the disinfectant preparation is completed, and each discharge electrode is adjusted to stop running.

[0147] In the embodiment, by determining whether the current water quality parameter matches the disinfectant target parameter, and stopping preparation when the liquid meets the expected disinfection requirement, the quality of the obtained disinfectant can be guaranteed, and the reliability of the disinfectant preparation device is improved.

[0148] ​In some embodiments, after step 402, the disinfectant preparation method further comprises the following steps:

[0149] In the case where it is determined that the current water quality parameter does not match the disinfectant target parameter, the control system controls each discharge electrode to start running, and after a preset time period, adjusts the running state of each discharge electrode to stop running.

[0150] The preset time period can be set according to specific conditions, for example, 10 minutes, 8 minutes, etc. Each discharge electrode stops discharging after a preset time period, which can ensure sufficient time for adjusting the water quality and making the disinfectant meet the expected demand, and can also avoid energy waste caused by excessive discharge.

[0151] Further, when the control system controls each discharge electrode to start running, the running power of each discharge electrode can be the maximum running power, so as to ensure the quality of the disinfectant.

[0152] In some embodiments, the disinfectant preparation method further comprises the following steps:

[0153] In response to a disinfectant preparation instruction, the control system controls the gas supply member to start running;

[0154] The control system controls the water inlet member to run until the water level in the water storage device reaches a preset water level;

[0155] The control system controls each discharge electrode to start running at a preset initial power until each discharge electrode reaches a preset stable running condition, and generates a disinfectant preparation self-adjustment instruction.

[0156] The disinfectant preparation instruction can be an instruction issued by a user. When the disinfectant preparation device is applied to a dishwasher, the control system can generate a disinfectant preparation instruction according to a cleaning instruction issued by the user, so as to prepare the disinfectant while cleaning, so that the dishwasher can be disinfected in time after cleaning, and the efficiency of the dishwasher is improved.

[0157] The control system first controls the gas supply member to start running, and the gas supply member can drive the gas in the gas channel to circulate, so that the tubular discharge cavity remains dry. During the running of the gas supply member, the control system controls the water inlet member to start running to inject water into the water storage device, and stops the water inlet member when the water level in the water storage device reaches a preset water level. At this time, a sufficient amount of water has been injected, and the water inlet member is stopped in time to avoid affecting the subsequent preparation effect due to the water level being too high or too low.

[0158] After the water injection is completed, the controller also controls each discharge electrode to start running at a preset initial power, which can be a small value, for example, a value less than the second running power. After each running power runs for a period of time (for example, 5-10 minutes), it is considered that each discharge electrode reaches the preset stable running condition and can run stably. At this time, the disinfectant solution preparation self-adjusting instruction is generated, which can better dynamically adjust the running condition of the discharge electrode according to the actual water quality, and the stability of the disinfectant solution preparation is higher.

[0159] In order to better understand the above-mentioned embodiments, the following will be explained in detail in combination with an optional embodiment. In an embodiment, as shown in FIG. 1, the disinfectant solution preparation method comprises the following steps. Figure 5

[0160] The control system controls the gas supply member (i.e., the gas pump) to start and continuously run, ensuring that no water enters the discharge cavity during the disinfectant solution preparation process. Then, the water inlet member (i.e., the water inlet pump) is controlled to start, and the water injection to the water storage device is started through the water inlet pipeline. After the water injection is completed, the water inlet pump is closed. Then, the high-voltage module of the glow discharge device is controlled to start working, all discharge electrode numbers are selected, and initial low-power high-voltage alternating current is input to all discharge electrodes for air discharge. After the entire glow discharge device is stable (for example, the discharge electrode continuously discharges at the initial low power for 5-10 minutes), the self-adjusting control program can be entered.

[0161] After entering the automatic adjustment control, the PH value of the PH meter and the conductivity value of the conductivity sensor are read, and the initial pH value (PH original) and the initial conductivity value (SI original) of the water are obtained. According to the comparison between the initial pH value and the initial conductivity value of the water solution and the preset pH threshold value PH1 and the preset conductivity threshold value SI1 (the value of commonly used tap water), the initial state of the water solution entering the water tank is judged, and the number and power of the discharge electrode required are determined. If PH original≧PH1 and SI original≦SI1, all electrodes are selected for discharge, and the discharge power is selected as the maximum running power value P2; if PH original<PH1 and SI original>SI1, one row of electrodes is selected for discharge, and the discharge power is selected as the medium power value P1 (i.e., the second running power). In this way, the parameters of the device are determined according to the water quality in the user's home.

[0162] Subsequently, every preset interval detection duration (for example, 5 minutes, 10 minutes), the PH value of the PH meter and the conductivity value of the conductivity sensor are read, and the current pH value (PH real) and the current conductivity value (SI real) are recorded, respectively. The number and power of the discharge electrode required are determined by judging whether the two values are large and the change amount, and the judgment logic is as follows:

[0163] ​If the change values of the pH value and the conductivity value, ΔPH, ΔSI (ΔPH = PHreal - PHoriginal, ΔSI = SImeal - SIoriginal) are greater than or equal to twice the second pH change threshold value (PHset) and the second conductivity change threshold value (SIset) (the second pH change threshold value and the second conductivity change threshold value can be determined by laboratory measurement), it is indicated that the time has exceeded the required discharge requirement, and the number of electrodes in one row and the medium second operating power P1 can be used for operation.

[0164] If PHset≤ ΔPH < 2*PHset and SIset≤ ΔSI < 2*SIset, it is indicated that the time has reached the required discharge requirement, and all the electrodes and the medium second operating power can be used for operation.

[0165] If ΔPH < PHset and ΔSI < SIset, it is indicated that the time does not meet the required discharge requirement, and all the electrodes and the maximum power value P2 need to be used for operation. After adjustment, the initial conductivity value is updated to the measured current conductivity value, and the initial acid-base value is updated to the measured current acid-base value to provide initial data for subsequent judgment.

[0166] When the total operating time of the glow discharge device reaches the preset disinfectant preparation time, i.e., at the end of the entire preparation time, the pH value and the conductivity value are read again, and it is judged whether the disinfection requirement is met. If yes, the drain pump is started, and the prepared disinfectant is discharged to the disinfection chamber of the dishwasher to perform the washing program for disinfection. If not, all the electrodes are used to continue operation at the maximum power value P2 for a period of time, such as 10 minutes, and after execution is completed, the drain pump is started, and the prepared disinfectant is discharged to the disinfection chamber of the dishwasher for disinfection.

[0167] It should be understood that although each step in the flowchart involved in each embodiment as described above is displayed in sequence according to the direction of the arrow, these steps are not necessarily executed in sequence according to the direction of the arrow. Unless otherwise explicitly stated herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each embodiment as described above can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed in rotation or alternation with at least part of other steps or steps or stages in other steps.
