Description

Technical Field

[0001] This application relates to the field of washing machine technology, and more specifically to an ozone degradation control method, electronic equipment, and washing equipment. Background Technology

[0002] In related technologies, ozone is often used in washing equipment to assist in the treatment of clothes. After the ozone is used, it cannot be directly discharged but needs to be degraded. To quickly degrade the ozone, air is blown into the washing equipment. The disadvantage of this method is that if the structure of the washing equipment is not tightly sealed, there will be a certain degree of ozone leakage, which may cause harm to the user. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The ozone generator 5 is connected to the ozone gas inlet 7 at the door seal via a hose 6.

[0039] Figure 3 A flowchart of an ozone degradation control method according to an embodiment of this application is shown. For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0040] A method for controlling ozone degradation may include the following steps:

[0041] In step S102, during the first ozone degradation stage, the fan is turned off, and the fan is used for air circulation in the treatment tank of the washing equipment.

[0042] In step S104, in the second ozone degradation stage after the first ozone degradation stage ends, the fan is controlled to start to accelerate ozone degradation.

[0043] The technical solution described in this application involves two stages of ozone degradation. In the first stage, the fan is turned off to allow for windless ozone degradation, preventing ozone diffusion and leakage due to excessive concentration. In the second stage, the fan is turned on to accelerate ozone degradation. Compared to the existing technology that uses continuous airflow, this method effectively reduces ozone leakage and improves safety.

[0044] In some embodiments, the conditions for the termination of the first ozone degradation stage include: ozone degradation to a first target ozone concentration, or the first ozone degradation stage reaching a first ozone degradation stage time threshold.

[0045] In this embodiment, the ozone degradation to the first target ozone concentration, or the first ozone degradation stage reaching the first ozone degradation stage time threshold, indicates the end of the first ozone degradation stage.

[0046] And / or, the conditions for the termination of the second ozone degradation stage include: ozone degradation to the second target ozone concentration, or the second ozone degradation stage reaching the second ozone degradation stage time threshold.

[0047] Wherein, the first target ozone concentration is greater than the second target ozone concentration, and the first target ozone concentration is less than the minimum concentration that would cause ozone diffusion and leakage under the condition that the fan is turned on.

[0048] In this embodiment, the ozone degradation to the second target ozone concentration, or the second ozone degradation stage reaching the second ozone degradation stage time threshold, are used as conditions for the end of the second ozone degradation stage.

[0049] In some embodiments, before entering the first ozone degradation stage described above in step S102, the method may further include the following steps:

[0050] In step S202, after the ozone treatment is completed, the first initial parameters of ozone degradation of the washing equipment are obtained.

[0051] The first initial parameters for ozone degradation are parameters measured before entering the first ozone degradation stage, including ozone concentration and at least one of the load weight and temperature.

[0052] In this embodiment, the initial parameters for the first ozone degradation may include ozone concentration and load weight.

[0053] The initial parameters for ozone degradation can include ozone concentration and temperature.

[0054] The initial parameters for ozone degradation can include ozone concentration, temperature, and load weight.

[0055] Load weight, ozone concentration, and temperature all affect ozone degradation time and are important factors influencing ozone degradation. The heavier the load, the slower the ozone degradation and the longer the degradation time. Higher ozone concentrations result in slower degradation and a longer degradation time. Higher temperatures lead to faster ozone degradation and a shorter degradation time.

[0056] In step S204, at least the time threshold for the first ozone degradation stage is determined based on the first initial parameters of ozone degradation.

[0057] In this embodiment, the time threshold for the first ozone degradation stage can be determined based on the initial parameters of the first ozone degradation and the final concentration of the first ozone degradation.

[0058] The first ozone degradation termination concentration is the maximum concentration at which ozone will not diffuse and leak under blowing conditions (i.e., when the fan is on). This maximum concentration can be an experimental or empirical value, and can be associated with information such as machine model and years of use. This embodiment does not limit its specific value. This first ozone degradation termination concentration can be used as the switching point between windless and windy ozone degradation, thus enabling the switching between windless and windy ozone degradation.

[0059] The first ozone degradation termination concentration serves as a reference parameter for the termination state and affects the degradation time as follows: the higher the first ozone degradation termination concentration, the shorter the degradation time; conversely, the lower the first ozone degradation termination concentration, the longer the degradation time.

[0060] When the degradation time is equal to or greater than the time threshold of the first ozone degradation stage, the actual ozone concentration inside the treatment tank will decrease to the aforementioned first ozone degradation termination concentration. In windy conditions, no diffusion or leakage will occur.

[0061] In related technologies, due to issues such as detection errors and incomplete local detection, the problem of localized residues cannot be effectively solved, and real-time ozone concentration cannot be accurately collected. Because of the inability to accurately collect real-time ozone concentration, control based on real-time ozone concentration is impossible. In this application, however, instead of using ozone concentration, a time parameter is used. Based on extensive data statistics, a time threshold for the first ozone degradation stage is determined. This first ozone degradation stage time threshold is used as a reference for the timing of switching from the first ozone degradation stage to the second ozone degradation stage. The technical solution is simpler and easier to implement.

[0062] After ozone treatment, during the first stage of ozone degradation, the ozone concentration is high, and blowing air may cause excessive ozone leakage. Therefore, the fan can be turned off in the first half of the degradation process, while the treatment tank continues to rotate, allowing the ozone to degrade naturally or through the residual heat from the previous stage. Once the ozone reaches the reference concentration or the first-stage ozone degradation time threshold, the second ozone degradation stage begins, and the fan is turned on to accelerate degradation. This not only reduces the risk of excessive ozone leakage but also helps accelerate degradation during the second ozone degradation stage.

[0063] Current technologies fail to consider the impact of load weight and temperature on ozone degradation, leading to insufficient degradation time and unacceptable ozone residue. Furthermore, these technologies rarely consider the influence of load weight on ozone degradation. Higher loads result in slower localized degradation, affecting the overall degradation rate. Existing technologies rely on detectors to assess degradation levels, which are prone to errors and incomplete detection of localized residues, failing to effectively address the issue of localized residues. Additionally, lower temperatures result in slower degradation rates; neglecting these factors can easily lead to insufficient degradation time and unacceptable ozone residue.

[0064] In this application, by considering four factors—load weight, ozone concentration, temperature, and the first ozone degradation termination concentration—the time threshold for the first ozone degradation stage can be determined more precisely, thus improving accuracy. Precise determination of the first ozone degradation stage time threshold allows for more accurate control of the timing of entering the second ozone degradation stage, thereby helping to avoid leakage caused by excessively high ozone concentrations in the second stage.

[0065] In one embodiment, the method may further include the following steps: if the first actual degradation time is less than the first ozone degradation stage time threshold, keep the fan off and continue recording the first actual ozone degradation time.

[0066] Wherein, the first actual ozone degradation time is the time counted from the start time in the first ozone degradation stage.

[0067] In this embodiment, if the first actual degradation time is less than the first stage ozone degradation time, it means that the ozone concentration is greater than the first ozone degradation termination concentration mentioned above. In this case, the second stage of windy degradation cannot be entered, and the first stage of windless degradation should continue.

[0068] In some embodiments, determining the time threshold for the first ozone degradation stage based at least on the first initial parameters of ozone degradation may further include the following steps:

[0069] Based on the initial parameters of the first ozone degradation, the time threshold distribution table of the first ozone degradation stage is consulted to determine the time threshold of the first ozone degradation stage.

[0070] The above-mentioned time threshold distribution table for the first ozone degradation stage includes the correspondence between the load weight range, ozone concentration range, temperature range and the time threshold for the first ozone degradation stage, or the correspondence between the load weight range, ozone concentration range and the time threshold for the first ozone degradation stage, or the correspondence between the ozone concentration range, temperature range and the time threshold for the first ozone degradation stage.

[0071] For example, the time threshold distribution table for the first ozone degradation stage includes Table 1, which shows the correspondence between ozone concentration ranges, temperature ranges, and time thresholds for the first ozone degradation stage.

[0072]

[0073] Generally speaking, under the condition that other factors remain unchanged, the larger the load weight range, the larger the time threshold of the first ozone degradation stage; the higher the temperature range, the smaller the time threshold of the first ozone degradation stage; and the higher the ozone concentration range, the larger the time threshold of the first ozone degradation stage.

[0074] In some embodiments, determining the time threshold for the first ozone degradation stage based at least on the first ozone degradation initial parameter includes:

[0075] Based on the first initial parameters of ozone degradation and the first target ozone concentration, the time required for the ozone concentration to degrade to the first target ozone concentration at the given load weight and temperature is determined and used as the time threshold for the first ozone degradation stage.

[0076] In this embodiment, the first target ozone concentration is the safe concentration for air blowing, that is, when the ozone concentration is less than or equal to the first target ozone concentration, the air blowing leakage will not exceed the standard.

[0077] The time required for the ozone concentration to degrade to the first target ozone concentration under the above-mentioned load weight and temperature is taken as the time threshold of the first ozone degradation stage.

[0078] In some embodiments, determining the time required for degradation from the ozone concentration to the first target ozone concentration at the load weight and the temperature, based on the first initial ozone degradation parameters and the first target ozone concentration, as the time threshold for the first ozone degradation stage, may further include the following steps:

[0079] Based on the above temperature, the initial degradation time required to reduce the ozone concentration from the above level to the above first target ozone concentration when the wind turbine is turned off is determined.

[0080] The initial degradation time is adjusted according to the load weight to obtain the time threshold of the first ozone degradation stage. The larger the load weight or the larger the load weight range, the greater the adjustment range of the initial degradation time.

[0081] In this embodiment, referring to Table 1, the first initial ozone concentration is the reference ozone concentration inside the cylinder before degradation. Alternatively, it can be a concentration range. Table 1 shows the time thresholds for the first ozone degradation stage corresponding to each temperature range under different first initial ozone concentrations.

[0082] For example, under the condition of an initial ozone concentration of 6 ppm and a temperature range of 25-35°C, the time threshold for the first ozone degradation stage is 16 minutes. The aforementioned initial ozone concentration of 6 ppm can also be a range of 5-7 ppm.

[0083] Table 2 shows the time thresholds for the first ozone degradation stage for multiple different loading segments within each temperature range, under the condition of an initial ozone concentration of 10 ppm. The initial ozone concentration of 10 ppm can also be modified to a range of 9-11 ppm.

[0084]

[0085]

[0086] For example, under the conditions of a temperature range of 25-35℃ and a load weight of ≤0.5kg, the time threshold for the first ozone degradation stage is 22.5min.

[0087] Under conditions of a temperature range of 50-65℃ and a load weight of >3kg, the time threshold for the first ozone degradation stage is 7min.

[0088] Taking 10ppm, 25-35℃, and 1.5~3kg as an example, if the load is less than or equal to 2kg, you can select 24 and set the degradation time to be the same as the initial degradation time; if the load is greater than 2kg but less than or equal to 3kg, you can select 25min to compensate for the impact of the increased load on the degradation effect.

[0089] In other embodiments of this application, the load amount can be the load weight or the load ratio (e.g., the ratio of the load volume to the volume of the washing chamber of the washing tub).

[0090] In some embodiments, the method may further include the following steps:

[0091] The first target ozone concentration is determined based on the load weight inside the treatment tank. The greater the load weight or the larger the load weight range, the higher the first target ozone concentration.

[0092] For example, when the weight of the clothing is 0.5 kg or less, the target ozone concentration is c1, which can be selected as 5-8 ppm, preferably 6 ppm; when the weight of the clothing is 0.5-1.5 kg, the target ozone concentration is c2, which can be selected as 9-12 ppm, preferably 10 ppm.

[0093] In some embodiments, the method may further include the following steps:

[0094] Based on the initial parameters of the first ozone degradation, the time threshold distribution table of the second ozone degradation stage is consulted to determine the time threshold of the second ozone degradation stage.

[0095] The time threshold distribution table for the second ozone degradation stage includes the correspondence between load weight ranges, ozone concentration ranges, temperature ranges, and the time thresholds for the second ozone degradation stage; or, it includes the correspondence between load weight ranges, ozone concentration ranges, and the time thresholds for the second ozone degradation stage; or, it includes the correspondence between ozone concentration ranges, temperature ranges, and the time thresholds for the second ozone degradation stage.

[0096] Specifically, the larger the load weight range, the larger the time threshold for the second ozone degradation stage; the higher the temperature range, the smaller the time threshold for the second ozone degradation stage; and the higher the ozone concentration range, the larger the time threshold for the second ozone degradation stage.

[0097] In this embodiment, the time threshold distribution table for the second ozone degradation stage is pre-generated. The second ozone degradation stage time threshold distribution table includes a second initial ozone concentration, which corresponds to multiple different temperature ranges; each temperature range corresponds to multiple load ranges; and each load range corresponds to a second ozone degradation stage time threshold.

[0098] Among them, the higher the temperature, the smaller the time threshold of the second ozone degradation stage;

[0099] The heavier the load, the longer the time threshold for the second ozone degradation stage.

[0100] Table 3 shows the time thresholds for the second ozone degradation stage for each load weight segment under different temperature ranges, provided the initial ozone concentration is 2-3 ppm.

[0101]

[0102] Taking a second initial ozone concentration of 2-3 ppm as an example, when the temperature is K1 (25-35℃), the time threshold T11 for the second ozone degradation stage for clothing weighing less than or equal to 0.5 kg can be selected as 22.5 min, the time threshold T12 for the second ozone degradation stage for clothing weighing (0.5-1.5] kg can be selected as 23 min, the time threshold T13 for the second ozone degradation stage for clothing weighing (1.5-3] kg can be selected as 24 min, and the time threshold T14 for the second ozone degradation stage for clothing weighing more than 3 kg can be selected as 25-26 min.

[0103] When the temperature is K2 (35-50℃), the time threshold T21 for the second ozone degradation stage with a load weight of less than or equal to 0.5 kg can be selected as 14 min, the time threshold T22 for the second ozone degradation stage with a load weight of 0.5-1.5 kg can be selected as 15 min, the time threshold T23 for the second ozone degradation stage with a load weight of (1.5-3) kg can be selected as 16 min, and the time threshold T24 for the second ozone degradation stage with a load weight of more than 3 kg can be selected as 17 min.

[0104] When the temperature is K3 (50-65℃), the time threshold T31 for the second ozone degradation stage with a load weight of 0.5 kg or less can be selected as 3.5 min, the time threshold T32 for the second ozone degradation stage with a load weight of (0.5-1.5] kg can be selected as 4 min, the time threshold T33 for the second ozone degradation stage with a load weight of (1.5-3] kg can be selected as 5 min, and the time threshold T34 for the second ozone degradation stage with a load weight of more than 3 kg can be selected as 6 min.

[0105] In some embodiments, the method may further include the following step: during the first ozone degradation stage, controlling the treatment tank to continue rotating.

[0106] In this embodiment, by controlling the treatment tank to continue rotating, washing and ozone degradation can be carried out simultaneously, which helps to improve the overall efficiency of the washing equipment and avoids having to wait until the washing is finished before performing ozone degradation.

[0107] In some embodiments, prior to entering the second ozone degradation stage described above, the method may further include the following steps:

[0108] The second initial parameters for ozone degradation of the washing equipment are obtained. The second initial parameters for ozone degradation include the first target ozone concentration and at least one of the load weight and temperature. The load weight and temperature are measured after the first ozone degradation stage ends and before the second ozone degradation stage begins, or the load weight and temperature are measured before the first ozone degradation stage begins.

[0109] The time threshold for the second ozone degradation stage is determined at least based on the aforementioned initial parameters for the second ozone degradation.

[0110] In this embodiment, the second initial parameters for ozone degradation include the first target ozone concentration and the load weight mentioned above.

[0111] In this embodiment, the second initial parameters for ozone degradation include the first target ozone concentration and temperature mentioned above.

[0112] In this embodiment, the second initial parameters for ozone degradation include the first target ozone concentration, temperature, and load weight.

[0113] In some embodiments, determining the time threshold for the second ozone degradation stage based at least on the second ozone degradation initial parameters may further include the following steps:

[0114] Based on the aforementioned initial parameters for the second ozone degradation, the time threshold distribution table for the second ozone degradation stage is consulted to determine the aforementioned time threshold for the second ozone degradation stage.

[0115] The above-mentioned time threshold distribution table for the second ozone degradation stage includes the correspondence between the load weight range, ozone concentration range, temperature range, and time threshold for the second ozone degradation stage; or, it includes the correspondence between the load weight range, ozone concentration range, and time threshold for the second ozone degradation stage; or, it includes the correspondence between the ozone concentration range, temperature range, and time threshold for the second ozone degradation stage.

[0116] Specifically, the larger the load weight range, the larger the time threshold for the second ozone degradation stage; the higher the temperature range, the smaller the time threshold for the second ozone degradation stage; and the higher the ozone concentration range, the larger the time threshold for the second ozone degradation stage.

[0117] In some embodiments, determining the time threshold for the second ozone degradation stage based at least on the second ozone degradation initial parameters may further include the following steps:

[0118] Based on the aforementioned second ozone degradation initial parameters and the aforementioned second target ozone concentration, the time required for the ozone concentration to degrade to the aforementioned second target ozone concentration at the aforementioned load weight and the aforementioned temperature is determined as the time threshold for the aforementioned second ozone degradation stage.

[0119] In some embodiments, determining the time required for degradation from the ozone concentration to the second target ozone concentration at the load weight and the temperature, based on the second initial ozone degradation parameters and the second target ozone concentration, as the time threshold for the second ozone degradation stage, may further include the following steps:

[0120] Based on the above temperature, the initial degradation time required to reduce the ozone concentration from the first target concentration to the second target concentration under the condition of fan operation is determined.

[0121] The initial degradation time is adjusted based on the load weight to obtain the time threshold for the second ozone degradation stage. The larger the load weight or the larger the load weight range, the greater the adjustment range of the initial degradation time.

[0122] In this embodiment, the time threshold for the second ozone degradation stage can be obtained by adjusting the initial degradation time based on the load weight using a lookup table. For example, referring to Table 3, the corresponding time threshold for the second ozone degradation stage can be determined by looking up the load weight range.

[0123] In some embodiments, the above method may further include the following steps:

[0124] In the first ozone degradation stage, if the ozone degradation time reaches the time threshold of the first ozone degradation stage, the ozone concentration is detected. If the ozone concentration is less than or equal to the first target ozone concentration, the second ozone degradation stage begins. If the ozone concentration is greater than the first target ozone concentration, the extension time of the first degradation stage is determined based on the difference between the ozone concentration and the first target ozone concentration.

[0125] In this embodiment, when the ozone degradation time reaches the time threshold of the first ozone degradation stage, it is necessary to determine whether the ozone concentration has dropped below the safe concentration. If the ozone concentration is less than or equal to the first target ozone concentration, it indicates that the ozone concentration has dropped below the safe concentration, and the fan can be started to blow air, thus entering the second ozone degradation stage.

[0126] If the ozone concentration exceeds the first target ozone concentration, it indicates that the first degradation stage needs to continue. The extension time of the first degradation stage can be determined based on the difference between the ozone concentration and the first target ozone concentration. This extension time can be a set value, an empirical value, or an experimental value, or it can be determined based on the current ozone concentration, the first target ozone concentration, and the temperature.

[0127] In one embodiment, during the second ozone degradation stage, if the second actual ozone degradation time is less than the second ozone degradation stage time threshold, the fan is controlled to remain on.

[0128] The second actual ozone degradation time is the time taken from the start of the second ozone degradation stage.

[0129] In this embodiment, during the second ozone degradation stage, the second actual ozone degradation time is recorded in real time.

[0130] Compare the second actual ozone degradation time with the second ozone degradation stage time threshold. If the second actual ozone degradation time is less than the second ozone degradation stage time threshold, it means that the actual ozone concentration is greater than the second ozone degradation termination concentration. Degradation should continue, and the fan should be kept on and not stopped.

[0131] In one embodiment, during the second ozone degradation stage, the degradation process ends when the second actual ozone degradation time is greater than or equal to the time threshold of the second ozone degradation stage.

[0132] In this embodiment, during the second ozone degradation stage, if the second actual ozone degradation time is greater than or equal to the second ozone degradation stage time threshold, it indicates that the ozone concentration is less than the second ozone degradation termination concentration. In this case, degradation can be terminated, and the fan can be stopped.

[0133] In some embodiments, under the same load weight and temperature, the time threshold for the first ozone degradation stage is greater than the time threshold for the second ozone degradation stage.

[0134] See Table 4 for the parameters related to segmented degradation.

[0135]

[0136] As shown in Table 4, under the condition of fixed temperature and load weight, the time threshold of the first ozone degradation stage is greater than that of the second ozone degradation stage.

[0137] For example, under the conditions of a temperature of 25-35℃ and a load weight of less than or equal to 0.5kg, the time threshold for the first stage is 7.5min, and the time threshold for the second stage is 3min.

[0138] The time threshold for the first ozone degradation stage is greater than that for the second ozone degradation stage. The advantages are as follows: a larger time threshold for the first ozone degradation stage helps to reduce the ozone concentration to below the first ozone degradation termination concentration during the windless degradation stage, preventing ozone leakage during the second windy degradation stage if the actual ozone concentration exceeds the first termination concentration. A smaller time threshold for the second ozone degradation stage is because the actual ozone concentration is already below the first termination concentration during this stage. Under these conditions, windy degradation can be completed quickly.

[0139] In some embodiments, the fan speed can also be detected, and the time threshold for the second ozone degradation stage can be determined based on the fan speed.

[0140] Theoretically, the faster the fan speed, the smaller the time threshold for the second ozone degradation stage; conversely, the slower the fan speed, the larger the time threshold. With other parameters fixed, such as concentration, temperature, and load weight, extensive experiments can be conducted to statistically determine the correlation between different fan speeds and different time thresholds for the second ozone degradation stage.

[0141] See appendix Figure 4A The flowchart shown represents another method for controlling ozone degradation; this method includes the following steps:

[0142] Step S01: After the ozone treatment for sterilization or deodorization is completed, the washing equipment needs to undergo degradation of the residual ozone concentration until a safe concentration is reached before the washing equipment can be turned on.

[0143] Step S02: Obtain the current ozone concentration inside the cylinder.

[0144] Step S03: Detect the current temperature inside the cylinder and determine the initial degradation time based on the temperature and the current ozone concentration.

[0145] For example, referring to Table 1 above, when the concentration inside the cylinder is 10 ppm, the time threshold T1 for the first ozone degradation stage at a temperature K1 of 25-35℃ can be selected as 24 min; the time threshold T2 for the first ozone degradation stage at a temperature K2 of 35-50℃ can be selected as 16 min; and the time threshold T3 for the first ozone degradation stage at a temperature K3 of 50-65℃ can be selected as 5 min.

[0146] Step S04: Obtain the weight of the clothes inside the drum. The weight of the clothes inside the drum can be extracted from the weight recorded after weighing at the beginning of the program.

[0147] Step S05: Adjust the degradation time based on the weight of the clothing.

[0148] See appendix Figure 4C When the temperature is K1, if the weight of the clothing W1 is less than or equal to 0.5 kg, the time threshold for the second ozone degradation stage is set to T11; if the weight of the clothing W2 is 0.5-1.5 kg, the time threshold for the second ozone degradation stage is set to T12; if the weight of the clothing W3 is 1.5-3 kg, the time threshold for the second ozone degradation stage is set to T13; if the weight of the clothing W4 is more than 3 kg, the time threshold for the second ozone degradation stage is set to T14.

[0149] See appendix Figure 4DWhen the temperature is K2, if the weight of the clothing W1 is less than or equal to 0.5 kg, the time threshold for the second ozone degradation stage is set to T21; if the weight of the clothing W2 is 0.5-1.5 kg, the time threshold for the second ozone degradation stage is set to T22; if the weight of the clothing W3 is 1.5-3 kg, the time threshold for the second ozone degradation stage is set to T23; if the weight of the clothing W4 is more than 3 kg, the time threshold for the second ozone degradation stage is set to T24.

[0150] See appendix Figure 4E When the temperature is K3, if the weight of the clothing W1 is less than or equal to 0.5 kg, the time threshold for the second ozone degradation stage is set to T31; if the weight of the clothing W2 is 0.5-1.5 kg, the time threshold for the second ozone degradation stage is set to T32; if the weight of the clothing W3 is 1.5-3 kg, the time threshold for the second ozone degradation stage is set to T33; if the weight of the clothing W4 is more than 3 kg, the time threshold for the second ozone degradation stage is set to T34.

[0151] Since the natural degradation of ozone takes a relatively long time, continuous air blowing during ozone degradation can easily cause leakage. Therefore, a segmented method of degrading ozone is adopted, with no air blowing in the first stage and air blowing in the second stage.

[0152] In some embodiments, see Appendix Figure 4B The diagram shows a staged ozone degradation process.

[0153] Step S001: Enter the ozone degradation process.

[0154] Step S002: Turn off the fan and record the first actual ozone degradation time t1.

[0155] After entering the ozone degradation process, the fan is turned off first, and the treatment tank is kept rotating. Degradation is carried out under windless conditions, and the first actual ozone degradation time t1 is recorded.

[0156] Step S003: Determine whether the first actual ozone degradation time t1 satisfies t1≥ti1.

[0157] If t1≥ti1, it means that the ozone concentration is relatively low at this time, the leakage caused by the blowing is small and will not exceed the standard, and step S09 is executed; if t1<ti1, it means that the ozone concentration is relatively high at this time and does not meet the blowing requirements, and the process returns to S07.

[0158] Where ti1 is the time threshold for the first ozone degradation stage. The time threshold for the first ozone degradation stage can be determined by referring to the distribution table of time thresholds for the first ozone degradation stage based on the initial parameters for the first ozone degradation.

[0159] Step S004: Start the fan and record the second actual ozone degradation time t2.

[0160] Step S005: Determine whether the second actual ozone degradation time t2 satisfies t2≥ti2.

[0161] The above-mentioned ti2 is the time threshold of the second ozone degradation stage, that is, the time required for the air-blown degradation to reach the second ozone degradation termination concentration. The second ozone degradation termination concentration is also the safe concentration, which can be selected as 0.05ppm or 0.15ppm.

[0162] In some embodiments, the time threshold of the second ozone degradation stage is determined by looking up the time threshold distribution table of the second ozone degradation stage based on the initial parameters of the second ozone degradation.

[0163] If t2 ≥ ti2, it means that the degradation has reached a safe concentration, the degradation process ends, and step S11 is executed. If t2 < ti2, it means that the degradation has not yet reached a safe concentration, and the process returns to step S004 to continue the air-blowing degradation.

[0164] Step S006: The ozone degradation process ends.

[0165] For example, when the initial ozone concentration is 10 ppm and the internal temperature is 25-35°C, and the load weight is less than or equal to 5 kg, ti2 can be selected as 3 min. When the load weight is 0.5-1.5 kg, ti2 can be selected as 3.5 min; when the load weight is 1.5-3 kg, ti2 can be selected as 4 min; and when the load weight is more than 3 kg, ti2 can be selected as 5 min.

[0183] In the natural degradation mode, the ventilation fan is off and the treatment tank is rotating; in the forced degradation mode, the ventilation fan is on and the treatment tank is rotating.
