Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a method and device for preparing disinfectant water, disinfectant equipment and a computer-readable storage medium. Background Art

[0002] With the continuous improvement of the quality of life, dishwashers have entered people's daily lives. Traditional dishwashers all use high-temperature water for sterilization, but the sterilization effect is limited. For this reason, a dishwasher using plasma sterilization technology has emerged in the prior art. This technology uses the glow discharge process to generate plasma. The active substances in the plasma, such as hydroxyl radicals (·OH), superoxide anion radicals (O2·-), ozone (O3), nitric oxide (NO) and nitrogen dioxide (NO2), interact with water molecules, causing significant changes in the chemical and physical properties of water, turning ordinary water into disinfectant water. Disinfectant water can fully contact with the dishes to be disinfected, destroy the cell membranes and DNA of microorganisms on the dishes, and inactivate the microorganisms, thereby achieving sterilization and disinfection of the dishes. The plasma concentration of disinfectant water is closely related to the effect of sterilization and disinfection. The plasma concentration of disinfectant water prepared by existing dishwashers is prone to deviation, which will directly affect the sterilization and disinfection effect and affect user use. Summary of the invention

[0003] In view of this, the present invention provides a disinfectant water preparation method, device, disinfectant equipment and computer-readable storage medium to solve the problem that the plasma concentration of disinfectant water in existing disinfectant equipment is prone to deviation, affecting the sterilization and disinfection effect.

[0004] In a first aspect, the present invention provides a method for preparing disinfectant water, which is applied to a disinfectant water preparation device, wherein the disinfectant water preparation device comprises a water storage structure and a discharge mechanism, wherein the discharge mechanism is arranged in the water storage structure, and the discharge mechanism is used to discharge and prepare the water in the water storage structure into disinfectant water; the method for preparing disinfectant water comprises:

[0005] The discharge mechanism is started;

[0006] Obtaining a first actual change value ΔS of the conductivity of the liquid in the water storage structure;

[0007] Obtaining a first conductivity preset change value ΔS0;

[0008] The power of the discharge mechanism is adjusted according to the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0.

[0009] Beneficial effect: The method for preparing disinfectant water of the present invention adjusts the power of the discharge mechanism according to the actual change value ΔS of the first conductivity in the water storage structure and the preset change value ΔS0 of the first conductivity. Since the plasma concentration in the disinfectant water is proportional to the conductivity of the disinfectant water, by measuring the conductivity of the liquid (which may be water, disinfectant water, or a mixture of water and disinfectant water) in the water storage structure, it is possible to know whether the plasma concentration in the disinfectant water meets the requirements or needs to continue to increase, and adjust the power of the discharge mechanism accordingly, thereby ensuring that the plasma concentration in the disinfectant water meets the requirements, ensuring the sterilization rate of the disinfectant water (for example, reaching 99.99%), and making the disinfectant water have a good disinfection and sterilization effect. The present invention uses the conductivity detection result as a basis to perform closed-loop control on the power of the discharge mechanism. This method can solve the problem that the plasma concentration of the disinfectant water is prone to deviation and affects the disinfection effect, and the disinfectant water produced within the preset preparation time has a good disinfection and sterilization effect.

[0010] In an optional implementation, the step of adjusting the power of the discharge mechanism according to the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0 includes:

[0011] When the first conductivity actual change value ΔS is greater than or equal to the first conductivity preset change value ΔS0, the discharge mechanism continues to operate at the original power P1;

[0012] When the first conductivity actual change value ΔS is less than the first conductivity preset change value ΔS0, the discharge mechanism operates at power P2, and the power P2 is greater than the original power P1.

[0013] Beneficial effect: In the method for preparing disinfectant water of the present invention, if the actual change value ΔS of the first conductivity is greater than or equal to the preset change value ΔS0 of the first conductivity, at this time, the concentration of the disinfectant water plasma currently prepared in the water storage structure meets the requirements, and the discharge mechanism can continue to operate at the original power P1; if the actual change value ΔS of the first conductivity is less than the preset change value ΔS0 of the first conductivity, at this time, the concentration of the disinfectant water plasma currently prepared in the water storage structure is low and does not meet the requirements, and the power of the discharge mechanism needs to be increased, and the discharge mechanism operates at power P2, and the power P2 is greater than the original power P1, so that the concentration of the disinfectant water plasma can be increased, ensuring that the disinfectant water finally prepared can meet the expected disinfection and sterilization effect.

[0014] In an optional embodiment, after the step of obtaining the first actual change value ΔS of the conductivity of the liquid in the water storage structure, the method further includes:

[0015] Determining whether the first conductivity actual change value ΔS is zero;

[0016] If yes, the exception count is increased by 1;

[0017] If no, the exception count is cleared.

[0018] Beneficial effect: In the disinfectant water preparation method of the present invention, if the actual change value ΔS of the first conductivity is zero, it proves that an abnormality has occurred, and the abnormality count is increased by 1; if the actual change value ΔS of the first conductivity is not zero, it proves that the preparation is normal, and the abnormality count is cleared. By accumulating abnormal conditions, measures can be taken in a timely manner when abnormal conditions continue to occur.

[0019] In an optional implementation, after the step of adding 1 to the abnormality count if yes, the following step further includes:

[0020] The discharge mechanism is turned off, and then started again after a time T1, and the discharge mechanism operates at a power of P2;

[0021] Determine whether the abnormal count is greater than N;

[0022] If yes, stop the preparation of disinfectant and sound an alarm;

[0023] If not, continue with the step of obtaining the first actual change value ΔS of the conductivity of the liquid in the water storage structure.

[0024] Beneficial effect: The disinfectant water preparation method of the present invention can temporarily shut down the discharge mechanism when an abnormal situation occurs, and restart it after time T1, and operate the discharge mechanism at a higher power. If the cumulative number of abnormal situations reaches N, it proves that there is a major problem in the preparation process, and it needs to be shut down and alarmed.

[0025] In an optional embodiment, the step of obtaining the first actual change value ΔS of the conductivity of the liquid in the water storage structure includes:

[0026] Obtaining a first conductivity actual value S1;

[0027] Get the original conductivity value S0;

[0028] The first conductivity actual change value ΔS= S1 - S0 .

[0029] Beneficial effects: The disinfectant water preparation method of the present invention obtains the first conductivity actual change value ΔS based on the first conductivity actual value S1 and the original conductivity value S0. The method is simple and has low computational difficulty.

[0030] In an optional implementation, before obtaining the first conductivity actual value S1, the method further includes:

[0031] Determine whether the conductivity detection time has arrived;

[0032] If yes, then obtain the first conductivity actual value S1;

[0033] If not, the discharge mechanism continues to operate at the original power P1 and continues to determine whether the conductivity detection time has arrived.

[0034] Beneficial effect: The disinfectant water preparation method of the present invention detects the first conductivity actual value S1 after a period of time after the discharge mechanism is started. This time is the conductivity detection time. The conductivity detection time can be selected according to different disinfectant water preparation requirements, with good control flexibility and a wide range of applications.

[0035] In an optional embodiment, before the discharge mechanism is started, the method further includes:

[0036] storing water in the water storage structure;

[0037] Get the original conductivity value S0.

[0038] Beneficial effects: The disinfectant water preparation method of the present invention has a accommodating cavity in the water storage structure, and the accommodating cavity is suitable for containing water. By storing water in the water storage structure, water can be conveniently replenished to prepare for the preparation of disinfectant water.

[0039] In an optional implementation, the step of starting the discharge mechanism includes: the discharge mechanism reaches a stable working state, and the discharge mechanism operates at a power P1.

[0040] Beneficial effect: In the method for preparing disinfectant water of the present invention, during the discharge process of the discharge mechanism, due to the unstable environment of the air system in the preparation device, directly increasing the power of the discharge mechanism is likely to form a continuous thick and long arc (called arcing), which will cause problems such as damage to the high-voltage power supply or melting of the electrode. Therefore, it is necessary to operate the discharge mechanism at power P1 after the discharge mechanism reaches a stable working state, and the stable working state refers to the working state when the discharge mechanism does not have an arcing phenomenon. At this time, the entire preparation process is stable and efficient, thereby ensuring the preparation of qualified disinfectant water.

[0041] In an optional embodiment, after the step of adjusting the power of the discharge mechanism according to the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0, the method further includes:

[0042] Determine whether the disinfection water preparation end time has arrived;

[0043] If the disinfection water preparation end time has come, obtaining a second conductivity actual change value ΔS' of the liquid in the water storage structure;

[0044] Determining whether the actual change value ΔS' of the second conductivity is less than or equal to zero;

[0045] If yes, then end the disinfection water preparation;

[0046] If not, determining whether the second conductivity actual change value ΔS' is greater than m times the second conductivity preset change value ΔS0';

[0047] If yes, drain the liquid in the water storage structure and sound an alarm;

[0048] If not, the discharge mechanism operates at power P2, and the estimated required preparation time T2 is obtained;

[0049] Continue to determine whether the disinfection water preparation end time has arrived;

[0050] If the disinfection water preparation end time has not yet arrived, the original conductivity value S0 is updated to the first conductivity actual value S1 and the process of determining whether the disinfection water preparation end time has arrived continues.

[0051] Beneficial effect: The disinfectant preparation method of the present invention needs to further judge whether the plasma concentration of the disinfectant has reached the target concentration after the disinfectant preparation ends. If the actual change value ΔS' of the second conductivity is less than or equal to zero, it proves that the plasma concentration of the disinfectant has reached the target concentration and meets the requirements. Otherwise, it is judged whether the actual change value ΔS' of the second conductivity is greater than m times the preset change value ΔS0' of the second conductivity, where m is a positive number. If so, it proves that the plasma concentration deviation of the disinfectant is too large, and an abnormality occurs in the preparation process. It is necessary to discharge the liquid in the water storage structure and alarm to remind the user. If not, it proves that it still takes a period of preparation to reach the target concentration, so the estimated preparation time T2 is estimated. In this way, a closed-loop control is formed to ensure that the prepared disinfectant meets the target requirements.

[0052] In an optional embodiment, if the disinfection water preparation end time has arrived, the step of obtaining the second conductivity actual change value ΔS' of the liquid in the water storage structure comprises:

[0053] Obtaining a second conductivity actual value S2;

[0054] Get the target conductivity value S n ;

[0055] The second conductivity actual change value ΔS'=S2-S n .

[0056] Beneficial effect: The disinfection water preparation method of the present invention is based on the second conductivity actual value S2 and the target conductivity value S n , obtain the actual change value ΔS' of the second conductivity, the method is simple and the calculation difficulty is small.

[0057] In an optional embodiment, after the step of if not, the discharge mechanism operates at power P2 and obtains the estimated preparation time T2, it also includes: updating the original conductivity value S0 to the second actual conductivity value S2 and continuing to determine whether the disinfection water preparation end time has arrived.

[0058] Beneficial effect: The disinfectant water preparation method of the present invention updates the original conductivity value S0 to the second conductivity actual value S2 to provide a data basis for the next conductivity judgment, making the judgment process more accurate and reliable, which is conducive to preparing disinfectant water that meets the target requirements.

[0059] In an optional embodiment, if yes, then the step of terminating the disinfectant water preparation includes: discharging the prepared disinfectant water in the water storage structure.

[0060] Beneficial effect: After the disinfectant water preparation method of the present invention is completed, the disinfectant water preparation is completed, and the disinfectant water meets the target requirements and can be used for disinfection equipment. At this time, the prepared disinfectant water in the water storage structure can be discharged for use.

[0061] In a second aspect, the present invention provides a disinfectant water preparation device for executing the disinfectant water preparation method as described above, the disinfectant water preparation device comprising:

The discharge mechanism is used to discharge and prepare the water in the water storage structure into disinfectant water. The conductivity detection component is used to detect the conductivity of the liquid in the water storage structure. This disinfectant water preparation device can prepare disinfectant water and detect the conductivity of the liquid in the water storage structure to provide a data basis for the preparation method, so as to control the disinfectant water preparation process.

[0067] Beneficial effects: The disinfectant water preparation device of the present invention has a discharge mechanism including a container, electrodes, a gas channel and a gas supply member. The discharge mechanism is simple and compact in structure and can efficiently realize a glow discharge process for the preparation of disinfectant water.

[0068] In an optional embodiment, a drainage mechanism is further included, and the drainage mechanism is arranged on the water storage structure to discharge the liquid prepared in the water storage structure.

[0069] Beneficial effects: The disinfectant water preparation device of the present invention can discharge disinfectant water that meets the target requirements or disinfectant water that does not meet the target requirements out of the water storage structure through the drainage mechanism, which is convenient for adjustment and control.

[0082] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0083] Combine the following Figure 1-Figure 3 , describing embodiments of the disinfectant water preparation method, device, disinfection equipment and computer-readable storage medium of the present invention.

[0084] According to an embodiment of the present invention, a disinfectant water preparation method is provided, which is applied to a disinfectant water preparation device. The disinfectant water preparation device includes a water storage structure 1 and a discharge mechanism. The discharge mechanism is arranged in the water storage structure 1. The discharge mechanism is used to discharge and prepare the water in the water storage structure 1 into disinfectant water. The disinfectant water preparation method includes:

[0085] The discharge mechanism starts;

[0086] Obtaining a first actual change value ΔS of the conductivity of the liquid in the water storage structure 1;

[0087] Obtaining a first conductivity preset change value ΔS0;

[0088] The power of the discharge mechanism is adjusted according to the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0.

[0089] This method for preparing disinfectant water adjusts the power of the discharge mechanism according to the actual change value ΔS of the first conductivity in the water storage structure 1 and the preset change value ΔS0 of the first conductivity. Since the plasma concentration in the disinfectant water is proportional to the conductivity of the disinfectant water, by measuring the conductivity of the liquid (which may be water, disinfectant water, or a mixture of water and disinfectant water) in the water storage structure 1, it can be known whether the plasma concentration in the disinfectant water meets the requirements or needs to continue to increase, and the power of the discharge mechanism is adjusted accordingly, so as to ensure that the plasma concentration in the disinfectant water meets the requirements, ensure the sterilization rate of the disinfectant water (for example, reaching 99.99%), and make the disinfectant water have a good disinfection and sterilization effect. The present invention uses the conductivity detection result as a basis to perform closed-loop control on the power of the discharge mechanism. This method can solve the problem that the plasma concentration of the disinfectant water is prone to deviation and affects the disinfection effect, and the disinfectant water produced within the preset preparation time has a good disinfection and sterilization effect.

[0090] The disinfectant water preparation method of this embodiment is applied to a disinfectant water preparation device, which includes a water storage structure 1 and a discharge mechanism. The water storage structure 1 can hold water, and the discharge mechanism is arranged in the water storage structure 1. The discharge mechanism is used to discharge and prepare the water in the water storage structure 1 into disinfectant water.

[0091] like Figure 2 As shown, the disinfectant water preparation method provided in this embodiment includes:

[0092] Step S01, the discharge mechanism is started;

[0093] When disinfectant water needs to be prepared, the discharge mechanism is started, the discharge mechanism begins to work, and the discharge mechanism prepares ordinary water into disinfectant water through a discharge process.

[0094] In this embodiment, the discharge mechanism generates plasma by glow discharge process, and the active substances in the plasma, such as hydroxyl radical (·OH), superoxide anion radical (O2·-), ozone (O3), nitric oxide (NO) and nitrogen dioxide (NO2), etc., interact with water molecules, causing significant changes in the chemical and physical properties of water, turning ordinary water into disinfectant water. Since the specific principle and process of glow discharge are the same as those in the prior art, they are not described here.

[0095] Typically, after the discharge mechanism is started, the discharge mechanism first operates at an initial low power to discharge the air.

[0096] Step S02, obtaining a first actual change value ΔS of the conductivity of the liquid in the water storage structure 1;

[0097] Usually, after the discharge mechanism runs for a period of time, the first actual conductivity change value ΔS of the liquid in the water storage structure 1 is obtained, and the time period is a preset time value, which is the conductivity detection time. At this time, the liquid in the water storage structure 1 may be ordinary water, disinfectant water, or a mixture of ordinary water and disinfectant water, which is related to the specific preparation process.

[0098] The first conductivity actual change value ΔS is obtained according to the first conductivity actual value S1 and the original conductivity value S0.

[0099] Of course, there is no limit to the length of time for conductivity detection.

[0100] Step S03, adjusting the power of the discharge mechanism according to the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0.

[0101] The first conductivity actual change value ΔS is compared with the first conductivity preset change value ΔS0. When the first conductivity actual change value ΔS reaches or exceeds the first conductivity preset change value ΔS0, the discharge mechanism can continue to operate at the original power, that is, the current power is not changed. When the first conductivity actual change value ΔS does not reach the first conductivity preset change value ΔS0, the power of the discharge mechanism needs to be increased to ensure that the prepared disinfectant water meets the requirements and can achieve the expected disinfection effect. The power refers to the input power of the discharge mechanism, or the discharge power.

[0102] Further, the step of adjusting the power of the discharge mechanism according to the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0 includes:

[0103] When the first conductivity actual change value ΔS is greater than or equal to the first conductivity preset change value ΔS0, the discharge mechanism continues to operate at the original power P1;

[0104] When the first conductivity actual change value ΔS is less than the first conductivity preset change value ΔS0, the discharge mechanism operates at power P2, and the power P2 is greater than the original power P1.

[0105] After respectively obtaining the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0, the two are compared. If the first conductivity actual change value ΔS is greater than or equal to the first conductivity preset change value ΔS0, the concentration of the prepared disinfection water plasma meets the requirements, and the power of the discharge mechanism does not need to be adjusted, and the discharge mechanism continues to operate at the original power P1. If the first conductivity actual change value ΔS is less than the first conductivity preset change value ΔS0, the concentration of the prepared disinfection water plasma does not meet the requirements, and the power of the discharge mechanism needs to be adjusted, specifically, the power of the discharge mechanism needs to be increased, so that the discharge mechanism operates at power P2, and the power P2 is greater than the original power P1, so as to accelerate the increase of the concentration of the plasma in the disinfection water.

[0106] Furthermore, after the step of obtaining the first actual change value ΔS of the conductivity of the liquid in the water storage structure 1, the method further includes:

[0107] Determining whether the first conductivity actual change value ΔS is zero;

[0108] If yes, the exception count is increased by 1;

[0109] If no, the exception count is cleared.

[0110] After obtaining the first actual conductivity change value ΔS of the liquid in the water storage structure 1, it is necessary to determine whether the first actual conductivity change value ΔS is zero. When the first actual conductivity change value ΔS is zero, it proves that after a period of preparation process, the plasma concentration of the liquid in the water storage structure has not changed. This situation is an abnormal situation and needs to be recorded so that corresponding measures can be taken later.

[0111] Specifically, determining whether the first conductivity actual change value ΔS is zero;

[0112] If yes, the exception count is increased by 1;

[0113] If no, the exception count is cleared.

[0114] Furthermore, if yes, after the step of adding 1 to the abnormality count, the method further includes:

[0115] The discharge mechanism is turned off, and then started again after time T1, and the discharge mechanism operates at power P2;

[0116] Determine whether the abnormal count is greater than N;

[0117] If yes, stop the preparation of disinfectant and sound an alarm;

[0118] If not, continue with the step of obtaining the first actual conductivity change value ΔS of the liquid in the water storage structure 1 .

[0119] When an abnormality is found in the preparation process, the abnormality count is increased by 1, and then the following measures are taken:

[0120] First, turn off the discharge mechanism. Since the current discharge mechanism is operating abnormally, it is necessary to suspend the operation of the discharge mechanism and preset a waiting time T1. After time T1, start the discharge mechanism again and make the discharge mechanism operate at a higher power P2 to increase the concentration of the disinfectant water plasma more quickly.

[0121] Afterwards, the accumulated value of the abnormality count is obtained to determine whether the abnormality count is greater than N, for example, N=2 or 3 or 5;

[0122] If the abnormal count is greater than N, it proves that the abnormal situation has occurred multiple times. If the number of occurrences is greater than N, the discharge mechanism may be damaged. It is necessary to stop the preparation of disinfectant and alarm to prompt the user to perform maintenance.

[0123] If the abnormal count is not greater than N, that is, the abnormal count is less than or equal to N, which proves that the number of abnormal situations does not occur very often, then the step of obtaining the actual change value ΔS of the first conductivity of the liquid in the water storage structure 1 is continued to prepare disinfectant water.

[0124] Furthermore, the step of obtaining the first actual change value ΔS of the conductivity of the liquid in the water storage structure 1 includes:

[0125] Obtaining a first conductivity actual value S1;

[0126] Get the original conductivity value S0;

[0127] The first conductivity actual change value ΔS= S1 - S0 .

[0128] Before obtaining the first actual conductivity change value ΔS, the first actual conductivity value S1 and the original conductivity value S0 need to be obtained respectively. The first actual conductivity change value ΔS is the difference between the first actual conductivity value S1 and the original conductivity value S0, that is, the first actual conductivity change value ΔS=S1-S0.

[0129] The first conductivity actual change value ΔS can represent the concentration of the disinfection water plasma prepared after the discharge mechanism has been running for a period of time.

[0130] Furthermore, before obtaining the first conductivity actual value S1, the method further includes:

[0131] Determine whether the conductivity detection time has arrived;

[0132] If yes, then obtain the first conductivity actual value S1;

[0133] If not, the discharge mechanism continues to operate at the original power P1 and continues to determine whether the conductivity detection time has arrived.

[0134] It is necessary to obtain the first conductivity actual value S1 after the discharge mechanism has been running for a period of time. This period of time is a preset time, that is, the conductivity detection time. After the discharge mechanism has been running for a period of time, for example, 2 minutes, it is determined whether the conductivity detection time has arrived, that is, whether the discharge mechanism has been running for 2 minutes. If the conductivity detection time has arrived, the first conductivity actual value S1 is obtained. Otherwise, the discharge mechanism continues to operate at the original power P1, and continues to determine whether the conductivity detection time has arrived, until the conductivity detection time is reached, and then the first conductivity actual value S1 is obtained.

[0135] Theoretically, after the discharge mechanism has been running for a period of time, the ordinary water in the water storage structure 1 will dissolve a certain amount of plasma to become disinfectant water. When the conductivity detection time is reached, the concentration of the disinfectant water plasma in the current water storage structure 1 can be obtained by obtaining the first actual conductivity value S1.

[0136] Furthermore, before the discharge mechanism is started, it also includes:

[0137] storing water in the water storage structure 1;

[0138] Get the original conductivity value S0.

[0139] Before the discharge mechanism is started, water or part of the water may be contained in the water storage structure 1. If the amount of water in the water storage structure 1 is insufficient, in order to prepare a sufficient amount of disinfectant water, it is necessary to store water in the water storage structure 1 before the discharge mechanism is started. The water storage structure 1 has a corresponding water storage mechanism until the amount of water in the water storage structure 1 reaches the requirement. Afterwards, the original conductivity value S0 in the water storage structure 1 is obtained. At this time, the water in the water storage structure 1 may be all ordinary water, or may contain part of the disinfectant water prepared last time. The conductivity value at this time, i.e., the original conductivity value S0, is obtained to provide a comparison basis for the subsequent acquisition of the first conductivity actual change value ΔS.

[0140] Furthermore, the step of starting the discharge mechanism includes: the discharge mechanism reaches a stable working state, and the discharge mechanism operates at power P1.

[0141] Due to the unstable environment of the air system in the preparation device, when the discharge mechanism is just started, if the power of the discharge mechanism is directly increased, it is easy to form a continuous thick and long arc (called arcing), which will cause problems such as damage to the high-voltage power supply or melting of the electrode. Therefore, when the discharge mechanism is just started, it is operated at a lower power. After the discharge mechanism reaches a stable working state, the power is gradually increased so that the discharge mechanism operates at power P1. The stable working state refers to the working state when the discharge mechanism does not have arcing. The above adjustment can make the entire preparation process stable and efficient, thereby ensuring the preparation of qualified disinfectant water.

[0142] Furthermore, after the step of adjusting the power of the discharge mechanism according to the first conductivity actual change value ΔS and the first conductivity preset change value ΔS0, the method further includes:

[0143] Determine whether the disinfection water preparation end time has arrived;

[0144] If the disinfection water preparation end time has come, then the second conductivity actual change value ΔS' of the liquid in the water storage structure 1 is obtained;

[0145] Determining whether the second conductivity actual change value ΔS' is less than or equal to zero;

[0146] If yes, then end the disinfection water preparation;

[0147] If not, determining whether the second conductivity actual change value ΔS' is greater than m times the second conductivity preset change value ΔS0', where m is a positive number;

[0148] If yes, the liquid in the water storage structure 1 is discharged and an alarm is sounded;

[0149] If not, the discharge mechanism operates at power P2 and obtains the estimated required preparation time T2;

[0150] Continue to determine whether the disinfection water preparation end time has arrived;

[0151] If the disinfection water preparation end time has not yet arrived, the original conductivity value S0 is updated to the first conductivity actual value S1 and the step of determining whether the disinfection water preparation end time has arrived is continued.

[0152] After the discharge mechanism continues to run for a period of time, it is necessary to determine whether the disinfection water preparation end time has been reached. Usually, before starting to prepare disinfection water, there is a preset time for the overall preparation time of disinfection water. For example, the overall preparation time is 10 minutes. After adjusting the power of the discharge mechanism according to the actual change value ΔS of the first conductivity and the preset change value ΔS0 of the first conductivity, it is determined whether the disinfection water preparation end time has been reached, that is, whether the discharge mechanism has been running for 10 minutes. If the disinfection water preparation end time has been reached, the second conductivity actual change value ΔS' of the liquid in the water storage structure 1 is obtained, and it is determined whether the second conductivity actual change value ΔS' is less than or equal to zero. If so, the disinfection water plasma concentration meets the requirements, the disinfection water preparation process has been completed, and the disinfection water preparation is ended; if not, the disinfection water plasma concentration does not meet the requirements, and it is necessary to determine whether the second conductivity actual change value ΔS' is too large, that is, to determine whether the second conductivity actual change value ΔS' is greater than m times the second conductivity preset change value ΔS0', where m is a positive number, for example, m is 2, 3, 6, etc. If yes, it proves that there is a major problem in the disinfection water preparation process, and it is necessary to discharge the liquid in the water storage structure 1, and alarm to prompt the user to perform maintenance; if not, the disinfection water plasma concentration is not too different from the target requirement at this time, so that the discharge mechanism is operated at power P2, and the estimated preparation time T2 is obtained, that is, the disinfection water plasma concentration can meet the requirements after the estimated time T2. After that, continue to execute the step of determining whether the disinfection water preparation end time has been reached. If the disinfection water preparation end time has not yet arrived, the original conductivity value S0 is updated to the first conductivity actual value S1 as the basis for the next comparison, and the judgment of whether the disinfection water preparation end time has arrived continues. In this way, a closed-loop control is formed to ensure that the prepared disinfection water meets the target requirements.

[0153] Furthermore, if the disinfection water preparation end time has arrived, the step of obtaining the second conductivity actual change value ΔS' of the liquid in the water storage structure 1 includes:

[0154] Obtaining a second conductivity actual value S2;

[0155] Get the target conductivity value S n ;

[0156] The second conductivity actual change value ΔS'=S2-S n .

[0157] Before obtaining the second conductivity actual change value ΔS', it is necessary to first obtain the second conductivity actual value S2 and the target conductivity value S n Before starting to prepare disinfectant water, a target conductivity value S is preset. n , target conductivity value S nAccording to the required disinfection water plasma concentration, when the second conductivity actual value S2 is equal to or greater than the target conductivity value S n When the concentration of the prepared disinfectant water plasma meets the target requirements.

[0158] The second conductivity actual change value ΔS' is the difference between the second conductivity actual value S2 and the target conductivity value S n The difference between the values ​​of S2 and S3, that is, the actual change value of the second conductivity ΔS' = S2-S n .

[0159] Further, if not, the discharge mechanism operates at power P2, and after the step of obtaining the estimated required preparation time T2, it also includes: updating the original conductivity value S0 to the second conductivity actual value S2 and continuing to determine whether the disinfection water preparation end time has arrived.

[0160] When the plasma concentration of the disinfectant water is not too different from the target requirement, the discharge mechanism operates at power P2 and estimates the expected preparation time T2. Then, the original conductivity value S0 is updated to the second actual conductivity value S2 as the basis for the next comparison, making the judgment process more accurate and reliable, which is conducive to the preparation of disinfectant water that meets the requirements.

[0161] Furthermore, if yes, the step of preparing disinfectant water is ended, including: discharging the prepared disinfectant water in the water storage structure 1.

[0162] If the disinfectant water plasma concentration meets the target requirement after the disinfectant water preparation end time has been reached, the disinfectant water preparation process has been completed. At this time, the disinfectant water needs to be discharged into a container or equipment that needs to use the disinfectant water to disinfect the items to be disinfected. The disinfectant water obtained by the preparation method of this embodiment has a high sterilization rate and good disinfection and sterilization effect.

[0177] Furthermore, the disinfection device is a dishwasher or a washing machine.

In this embodiment, the disinfection device is specifically a dishwasher, and the storage bin for the items to be disinfected is specifically a dishwasher tank, and the inside of the dishwasher tank is suitable for placing dishes, etc., and the drainage pipe of the disinfection water preparation device is connected to the dishwasher tank, and the prepared disinfection water can be discharged into the dishwasher tank.

[0179] The disinfection device has a main control module, which has a high-voltage module. The high-voltage module is electrically connected to the discharge mechanism, such as being electrically connected to the electrode 4 through a wire. The high-voltage module is used to control the operation of the discharge mechanism. The high-voltage module can input high-voltage alternating current to the electrode 4 to discharge the electrode. Of course, the main control module is also pre-set with a program for preparing disinfectant water.

[0180] In order to explain the method for preparing disinfectant water of the disinfection device of the present invention in detail, a specific example is given, such as Figure 3 As shown, the disinfectant water preparation method of this example includes the following steps:

[0181] When it is necessary to prepare disinfectant water, the procedure for preparing disinfectant water is started.

[0182] The main control module controls the air supply component 6 to start working, blowing air into the container 3 to blow out the water vapor inside the container 3, so as to ensure that there is no water vapor in the container 3 during the entire preparation process.

[0183] The main control module controls the water inlet pump 7 to start working, and stores water in the water storage structure 1 through the water storage pipe.

[0184] When the water volume reaches the requirement, the water storage is completed, the water inlet pump 7 is turned off, and the original conductivity value S0 of the liquid in the water storage structure 1 at this time is detected by the conductivity detection element 2.

[0185] The main control module controls the high-voltage module to start working, and the high-voltage module inputs high-voltage AC to the electrode 4, and the electrode 4 operates at an initial low power to discharge the air near the electrode. After that, the discharge power can be gradually adjusted to make the discharge mechanism tend to be stable. When the discharge mechanism reaches a stable working state, the electrode power is increased to power P1, and the discharge mechanism operates at power P1.

[0186] To determine whether the conductivity detection time has arrived, after the discharge mechanism has been running for a period of time, such as 5 minutes, 6 minutes, etc., it is necessary to detect the real-time conductivity value of the liquid in the water storage structure 1 to determine whether there is a change.

[0187] If the conductivity detection time has come, the first actual conductivity value S1 of the liquid in the water storage structure 1 is detected by the conductivity detection element 2. According to the first actual conductivity value S1 and the original conductivity value S0, the first actual conductivity change value ΔS=S1-S0 is calculated.

[0188] Afterwards, it is determined whether the first conductivity actual change value ΔS is zero.

[0189] If the first conductivity actual change value ΔS is zero, it means that the discharge mechanism has a discharge abnormality during this period, and the abnormality count is increased by 1, and then the high-voltage module is turned off, the discharge mechanism is turned off, and the discharge mechanism is started again after time T1. The discharge mechanism runs at power P2 for a fixed time and then the conductivity value of the conductivity detection element 2 is re-read.

[0190] Then, it is determined whether the abnormal count is greater than N. If so, the preparation of the disinfectant is stopped and an alarm is sounded. If not, the step of determining whether the conductivity detection time has arrived is continued.

[0191] If the conductivity detection time has not arrived, the discharge mechanism continues to operate at the original power P1 and continues the step of determining whether the conductivity detection time has arrived.

[0192] If the first conductivity actual change value ΔS is not zero, the abnormality count is cleared, and then it is determined whether the first conductivity actual change value ΔS is greater than or equal to the first conductivity preset change value ΔS0. The first conductivity preset change value ΔS0 can be determined by laboratory measurement.

[0193] If the first conductivity actual change value ΔS is greater than or equal to the first conductivity preset change value ΔS0, it means that the discharge mechanism can remain stable during this period of time and has met the required discharge requirements, and the discharge mechanism continues to operate at the original power P1; if the first conductivity actual change value ΔS is less than the first conductivity preset change value ΔS0, it means that the discharge mechanism is intermittent and unstable during this period of time, and in the subsequent detection time period, it is necessary to appropriately increase the discharge power of the glow discharge, and the discharge mechanism operates at power P2, which is greater than the original power P1, so that the amount of active substances generated increases, the plasma concentration is increased, and the conductivity increases.

[0194] Afterwards, the discharge mechanism continues to operate for a period of time to determine whether the disinfectant water preparation end time has arrived. The disinfectant water preparation end time can be 10 minutes, 20 minutes, etc.

[0195] If the disinfection water preparation end time has come, the conductivity detection element 2 detects the second conductivity actual value S2 of the liquid in the water storage structure 1 at this time, and then according to the second conductivity actual value S2 and the target conductivity value S n , calculate the actual change value of the second conductivity ΔS'=S2-S n Among them, the target conductivity value S n This is the preset value before the disinfection water preparation program starts.

[0196] Afterwards, it is determined whether the second conductivity actual change value ΔS' is less than or equal to zero. If so, the drainage pump 8 is started to discharge the disinfectant water prepared in the water storage structure 1, such as to the inner tank of the dishwasher, thereby ending the preparation of disinfectant water, and then the washing degree of the dishwasher can be performed. If not, it is determined whether the second conductivity actual change value ΔS' is greater than m times the second conductivity preset change value ΔS0', where m is a positive number, such as m=3. If so, the liquid in the water storage structure 1 is discharged and an alarm is sounded, ending the preparation of disinfectant water, and then the washing degree of the dishwasher can be performed; if not, the discharge mechanism is operated at power P2, and the estimated preparation time T2 is obtained, and then the original conductivity value S0 is updated to the second conductivity actual value S2 and the step of determining whether the disinfectant water preparation end time has been reached is continued.
