Description

Technical Field

[0001] The present application relates to the technical field of clothing processing, and in particular to a drying and sterilization method, a control device and clothing processing equipment. Background Art

[0002] Currently, the drying temperature of clothes in clothing processing equipment with drying function is generally 50-70°C, and the sterilization rate of Staphylococcus aureus is generally within 99.9%. However, mold and other fungi on clothes require higher temperatures to be removed. Therefore, simply sterilizing clothes with high-temperature airflow will result in incomplete sterilization.

[0003] In the related art, thorough sterilization is achieved by introducing ozone into the clothing treatment drum during the clothing drying process. However, introducing ozone during the high-temperature air blowing process will cause the ozone to be consumed faster, which will extend the sterilization time. At the same time, ozone leakage is likely to occur and pollute the external environment. Summary of the invention

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is only a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0041] It should be understood that the "plurality" mentioned herein refers to two or more than two. In the description of the implementation modes of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the implementation modes of the present application, in the implementation modes of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit certain different

[0042] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0043] In real life, users are prone to various odors, such as smoke, sweat, hot pot, snail noodle, etc. In related technologies, washing machines are combined with nano-photocatalytic technology to use light of a specific wavelength to excite nano-photocatalysts to remove odors from clothes in washing machines. However, this simple use of nano-photocatalytic technology to remove odors from clothes cannot completely remove odors from clothes.

[0044] In the related technology, the high-temperature airflow during the clothes drying process can reach 50℃~70℃, which can basically achieve comprehensive sterilization of Staphylococcus aureus. However, for molds and Pseudomonas aeruginosa that can withstand high temperatures, they cannot be effectively and completely eliminated by high-temperature drying airflow alone. Introducing ozone and other gases into the clothing treatment drum during the drying process can effectively remove molds, Pseudomonas aeruginosa, etc., but introducing ozone and other gases during the high-temperature air blowing process will accelerate the consumption of ozone and prolong the sterilization time, and ozone leakage may also occur and pollute the external environment.

[0045] In order to solve the above technical problems, the embodiment of the present application provides a clothes processing device, the clothes processing device comprising:

[0046] During the clothes drying process, the heating device and the air supply component are controlled to start operation, the clothes processing drum is controlled to rotate, and in the process of controlling the rotation of the clothes processing drum, it is determined whether the execution time of the sterilization program has been reached;

[0047] When the execution time of the sterilization program is reached, the drying parameters are obtained, and the target sterilization parameters are determined according to the drying parameters;

[0048] Enter the sterilization program, control the heating device and the air supply component to stop running, and make the clothing treatment drum rotate at a preset rotation and stop ratio, and input ozone into the clothing treatment drum according to the target sterilization parameters.

[0049] In this embodiment, by controlling the air supply component to stop running when the execution time of the sterilization program is reached, it is prevented that the high-temperature airflow accelerates the consumption of ozone and prolongs the sterilization time, and it is prevented that ozone leaks into the external environment with the high-temperature airflow and pollutes the external environment. After the sterilization program is completed, the heating device and the air supply component are controlled to start again, thereby ensuring the drying effect of the clothes. Controlling the heating device to stop running during the sterilization process can prevent the heating device from working for a long time when there is no blowing and being damaged.

[0050] Furthermore, the timing for executing the sterilization program is determined based on the drying time of the clothes drying process reaching the set drying time or the temperature difference of the inlet and outlet air of the clothes treatment drum reaching the set temperature difference. At this time, the moisture content of the clothes in the clothes treatment drum is low, and the drum contains wet steam evaporated during the drying process of the clothes. The wet steam evaporated from the clothes can accelerate the dissolution and diffusion of ozone, so that the ozone quickly reaches the target concentration, and a certain humidity will cause the bacterial cell membrane to open, making it easier for ozone to act on the cells, which can further enhance the sterilization effect.

[0051] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples can be combined with each other if there is no conflict.

[0052] First, the execution body of the drying and sterilization method of this embodiment is introduced.

[0053] The drying and sterilization method of this embodiment is applied to a clothes processing device. The clothes processing device of this embodiment may have only a drying function or may have both a drying function and a washing function. The structure of the clothes processing device may be a drum type or a pulsator type. Figure 1 Taking a drum type clothes treatment device as an example, the clothes treatment device comprises a housing 1 and a clothes treatment drum 3. When the clothes treatment device has only a drying function, the clothes treatment drum 3 is rotatably arranged in the housing 1, and the wall of the clothes treatment drum 3 does not have a flow opening. When the clothes treatment device has both a drying function and a washing function, an outer drum is further arranged in the housing 1, and the clothes treatment drum 3 is rotatably arranged as an inner drum in the outer drum, and a flow opening is arranged in the wall of the clothes treatment drum 3, and washing water or air flows between the clothes treatment drum 3 and the outer drum through the flow opening.

[0054] The housing 1 is also provided with a clothes delivery opening, which corresponds to the opening of the clothes processing tub 3. The clothes processing device comprises a door 2, which is provided at the clothes delivery opening and is used to open and close the clothes delivery opening.

[0055] The clothing inlet is also provided with a door seal, which can fit tightly against the mouth of the clothing treatment tub 3 when the machine door closes the clothing inlet, preventing water or air in the clothing treatment tub 3 from overflowing from the gap between the machine door and the mouth of the clothing treatment tub 3.

[0056] The clothing processing device also includes a drying system, which includes a heating device 6, an air supply component 7 and an air duct component 5. The clothing processing drum 3 is provided with an air inlet 8 and an air return port 4. The air inlet 8 is provided at the door seal, and the return air port 4 is provided at the bottom of the clothing processing drum 3. The air duct component 5 connects the return air port 4 with the air inlet end of the air supply component 7, and the air duct component 5 also connects the air inlet 8 with the air outlet end of the air supply component 7. The heating device 6 can heat the air flow in the air duct component 5. The air supply component 7 is, for example, a fan, and the heating device 6 can be an electric heating device or a heat pump system. Temperature sensors are also provided at the air inlet 8 and the return air port 4, respectively, for detecting the temperature of the air inlet 8 and the temperature of the return air port 4.

[0057] Furthermore, the clothing treatment device further comprises an ozone generator 9 , which is disposed in the housing 1 and is used for generating ozone and can pass the ozone into the clothing treatment tub 3 through the ozone inlet 10 .

[0058] In other feasible embodiments, the clothing treatment device may also be connected to an external ozone generator 9. When the clothing needs to be sterilized by ozone, the ozone generated by the external ozone generator 9 is introduced into the clothing treatment drum 3 through the ozone inlet 10 via an external pipeline.

[0059] The drying and sterilization process of this embodiment is introduced in detail below.

[0060] Figure 2 This is one of the drying and sterilization flow charts provided in the embodiment of the present application, refer to Figure 2 The drying and sterilization flow chart of this embodiment includes the following steps:

[0061] S21. During the clothes drying process, the heating device and the air supply component are controlled to start and operate, the clothes processing drum is controlled to rotate, and during the process of controlling the rotation of the clothes processing drum, it is also determined whether the timing for entering the sterilization program has been reached.

[0062] Specifically, during the clothes drying process, the heating device and the air supply component need to be controlled to start, the heating device heats the air in the air duct component, and the air supply component drives the hot air flow in the air duct component into the clothes processing drum, and at the same time brings the hot and humid air flow in the clothes processing drum into the air duct component. During the drying process, the clothes processing drum is in a rotating state to improve the uniform drying effect of the clothes.

[0063] The heating device can be an electric heating device or a heat pump system. In the case where the heating device is a heat pump system, the heat pump system includes a refrigerant circulation loop composed of a compressor, a condenser, an electronic expansion valve and an evaporator. During the clothes drying process, by controlling the compressor and the air supply component to start, the evaporator can condense the hot and humid airflow entering the air duct component from the return air port to form a dry and cold airflow, and the evaporator can heat the dry and cold airflow to generate a hot airflow.

[0064] In the process of controlling the rotation of the laundry treatment drum, it is also determined whether the execution timing of the sterilization program has been reached, so that the sterilization program is executed when the execution timing of the sterilization program has been reached.

[0065] S22. When the execution time of the sterilization program is reached, a drying parameter is obtained, and a target sterilization parameter is determined according to the drying parameter.

[0066] Specifically, when the sterilization program is executed, the humidity of the clothes is within the set humidity range and has not reached the preset dryness judgment condition. At this time, the clothes are dried to a state with a low moisture content but not completely dry. At this time, the drum contains wet steam evaporated from the clothes, which is not only conducive to the dissolution and diffusion of ozone and the rapid increase of ozone concentration, but also a certain humidity will open the bacterial cell membrane, making it easier for ozone to interact with cells, which is more conducive to sterilization. In addition, the clothes in this humidity state will not affect the entire drying process. If the air supply component and the heating device are turned off when the humidity of the clothes is high, the temperature in the clothes treatment drum will be reduced after the sterilization program. When the air supply component and the heating device are started again, the heating process will be slow, which will affect the entire drying process.

[0067] Exemplarily, when the sterilization program is executed, the moisture content of the clothes is 70%-90%, and the humidity of the wet steam in the drum is 60%-85%.

[0068] After determining that the timing for executing the sterilization program has arrived, before introducing ozone into the clothing treatment drum, the target sterilization parameters of the sterilization program are determined based on the drying parameters, so that ozone can be introduced into the clothing treatment drum with the target sterilization parameters during the subsequent sterilization process to ensure efficient sterilization of the clothes.

[0069] The drying parameters include at least the temperature inside the laundry treatment drum; the target sterilization parameters include the target ozone concentration in the laundry treatment drum, and / or the target ozone flow time, and / or the target ozone degradation time.

[0070] S23, entering the sterilization program, controlling the heating device and the air supply component to stop running, and rotating the clothes processing drum at a preset rotation-stop ratio, and inputting ozone into the clothes processing drum according to the target sterilization parameters.

[0071] Specifically, after entering the sterilization program, by controlling the heating device and the air supply component to stop running, it is possible to avoid the high-temperature airflow accelerating the consumption of ozone and prolonging the sterilization time, and to avoid the ozone leaking into the external environment with the high-temperature airflow and polluting the external environment. At the same time, it is also possible to avoid the heating device being damaged by long-term operation when not blowing air. In the sterilization program, the source of ozone introduced into the clothing treatment drum can be the ozone generator provided by the clothing treatment equipment, and the source of ozone can also be an ozone generator independent of the clothing treatment equipment and connected to the clothing treatment drum. The ozone generator is, for example, an ozone generator, and ozone is ozone. In the sterilization program, by introducing ozone into the clothing treatment drum with the target sterilization parameters corresponding to the current drying parameters, efficient and thorough removal of clothing can be achieved without affecting the overall drying time of the clothing.

[0072] In some embodiments, in the sterilization program, the laundry treatment drum is controlled to maintain a rotating state and rotate at a preset rotation-stop ratio to promote a uniform distribution effect of ozone in the laundry treatment drum. The rotation frequency of the laundry treatment drum in the sterilization program is not specifically limited. For example, the rotation-stop ratio of the laundry treatment drum in the sterilization program is rotation for 115 seconds and stop for 5 seconds.

[0073] In this embodiment, there are multiple ways to determine whether the timing for executing the sterilization program has arrived.

[0074] In one example, if Figure 3 The flowchart shown in FIG. 1 includes the following steps to determine whether the timing for executing the sterilization procedure has been reached:

[0075] S31, obtaining the drying time of the clothes processing equipment;

[0076] S32: When the drying time reaches the set time, it is determined that the time to execute the sterilization program has arrived.

[0077] Specifically, when the drying time reaches the set time, it means that the humidity of the clothes is within the set humidity range and has not reached the preset dryness judgment condition, and it is determined that the time to execute the sterilization program has been reached. At this time, the wet steam evaporated from the clothes in the drum will accelerate the dissolution and diffusion of ozone, and the wet steam in the drum will also open the cell membrane of bacteria, making it easier for ozone to interact with cells and improve the sterilization effect. Moreover, entering the sterilization program under this humidity state will not affect the entire drying process. When the drying time does not reach the set time, the time to execute the sterilization program has not been reached, and the clothes continue to be dried.

[0078] The set time is related to the initial weight of the clothes before drying, and the greater the weight of the dehumidified clothes, the longer the set time. Different weight levels of clothes correspond to different set times. The set drying time is determined by obtaining the weight of the dehumidified clothes before drying, and when the clothes drying time reaches the set drying time, the sterilization program is executed.

[0079] In another example, if Figure 4 The flowchart shown in the figure, determining whether the sterilization procedure has been achieved includes the following steps:

[0080] S41, obtaining the air inlet temperature and air outlet temperature of the laundry processing drum;

[0081] S42, determining the temperature difference between the inlet air temperature and the outlet air temperature;

[0082] S43. When the temperature difference is less than or equal to the set temperature difference, it is determined that the timing for executing the sterilization program has been reached.

[0083] Specifically, during the drying process, the inlet air temperature and the return air temperature of the clothing treatment drum are used to obtain the temperature difference based on the inlet air temperature and the return air temperature. When the temperature difference is less than or equal to the set temperature difference, it means that the humidity of the clothing is in the set humidity range and has not reached the preset dryness judgment condition, and it is determined when the execution time of the sterilization program has been reached. At this time, the wet steam evaporated from the clothing in the drum will accelerate the dissolution and diffusion of ozone, and the wet steam in the drum will also open the cell membrane of bacteria, making it easier for ozone to interact with cells and improve the sterilization effect. Moreover, entering the sterilization program under this humidity state will not affect the entire drying process. When the temperature difference is greater than the set temperature difference, the inlet air temperature and the return air temperature will continue to be monitored until the temperature difference is less than or equal to the set temperature difference. Among them, the range of the set temperature difference is, for example, 12°C-18°C.

[0084] In this embodiment, there are multiple ways to determine the target sterilization parameters according to the drying parameters.

[0085] In one example, the drying parameters include the temperature inside the clothing treatment drum, and the target sterilization parameters of ozone are determined based on the drying parameters, including: obtaining the temperature inside the drum, determining the target sterilization parameters based on the temperature inside the drum, and the higher the temperature inside the drum, the smaller the value of the target sterilization parameters.

[0086] Specifically, the control device of the clothing treatment equipment stores the corresponding relationship between the parameter value of the target sterilization parameter and the temperature in the barrel. Different barrel temperature intervals correspond to different parameter values ​​of the target sterilization parameter, and the higher the barrel temperature, the smaller the parameter value of the target sterilization parameter corresponding to the barrel temperature interval. This is because the higher the barrel temperature, the higher the barrel temperature during the introduction of ozone into the clothing treatment barrel and the ozone degradation process. It is more conducive to improving the sterilization effect during the introduction of ozone, and the remaining ozone can be degraded more quickly after the ozone is stopped. Therefore, a smaller sterilization parameter value can be used to obtain a better sterilization effect. The lower the barrel temperature, the less conducive it is to improving the sterilization effect during the introduction of ozone, and after the ozone is stopped, the barrel temperature will drop to a temperature range that is not conducive to ozone degradation, which will cause the ozone degradation time to become longer, and the parameter value of the sterilization parameter needs to be appropriately increased.

[0087] For example, when the temperature in the cylinder is lower than the first temperature, the target concentration of ozone is determined to be C2, the target ozone passage time is tc2, and the target ozone degradation time is tj2;

[0088] When the temperature in the cylinder is greater than or equal to the first temperature and less than the second temperature, the target concentration of ozone is determined to be C1, the target ozone passage time is tc1, and the target ozone degradation time is tj1;

[0089] When the temperature in the cylinder is greater than or equal to the second temperature, the target concentration of ozone is determined to be C3, the target ozone passage time is tc3, and the target ozone degradation time is tj3.

[0090] Exemplarily, the first temperature ranges from 50°C to 60°C, preferably 55°C; the second temperature ranges from 60°C to 65°C, preferably 65°C;

[0091] Among them: C2>C1>C3, tc2>tc1>tc3, tj2>tj1>tj3; C31<C32, tc31<tc32, tj31<tj32.

[0092] Exemplarily, C1 ranges from 7 ppm to 12 ppm, preferably 10 ppm, tc1 ranges from 10 min to 20 min, preferably 15 min, and tj1 ranges from 4 min to 8 min, preferably 5 min.

[0093] The range of C2 is 10ppm to 15ppm, preferably 12ppm to 13ppm, the range of tc2 is 15min to 25min, preferably 20min, and the range of tj2 is 5min to 10min, preferably 8min.

[0094] The range of C3 is 4ppm~10ppm, preferably 6ppm, the range of tc3 is 10min~20min, preferably 12min, and the range of tj3 is 3min~-8min, preferably 4min;

[0095] In another example, the drying parameters include the temperature inside the clothing treatment drum and the initial weight of the clothing before drying, and the target sterilization parameters of the ozone are determined according to the drying parameters, including: obtaining the temperature inside the drum, and when the temperature inside the drum is less than the set temperature, determining the target sterilization parameters according to the temperature inside the drum, and the higher the temperature inside the drum, the smaller the value of the target sterilization parameters; when the temperature inside the drum is greater than or equal to the set temperature, determining the target sterilization parameters according to the initial weight of the clothing, and the larger the initial weight of the clothing, the larger the value of the target sterilization parameters.

[0096] Specifically, under normal circumstances, the drying temperature will rise to a higher temperature only when the weight of the clothes in the laundry treatment drum is heavy. The heavier the clothes, the smaller the effect of throwing the clothes when the laundry treatment drum rotates, and the worse the uniformity of the temperature in the drum. Therefore, when the temperature in the drum reaches the set temperature, it means that the weight of the clothes in the drum is heavy at this time, and the target sterilization parameters need to be further determined based on the weight of the clothes. The set temperature is, for example, 60℃~70℃.

[0097] The control device of the clothing treatment equipment stores the corresponding relationship between the parameter value of the target sterilization parameter and the initial weight of the clothing. Different initial weight intervals of clothing correspond to different parameter values ​​of the target sterilization parameter, and the larger the initial weight of the clothing, the larger the parameter value of the target sterilization parameter corresponding to the initial weight interval of the clothing. For example, when the initial weight of the clothing is between 3kg and 4kg, the target concentration of the sterilization parameter is determined to be C31, the target ozone passage time is tc31, and the target ozone degradation time is tj31; when the initial weight of the clothing is between 5kg and 6kg, the target concentration of the sterilization parameter is determined to be C32, the target ozone passage time is tc32, and the target ozone degradation time is tj32.

[0098] Exemplarily, the range of C31 is 4ppm~7ppm, preferably 5ppm, the range of tc31 is 10min~20min, preferably 14min, and the range of tj3 is 3min~6min, preferably 4min; the range of C32 is 5ppm~10ppm, preferably 7ppm, the range of tc32 is 10min~20min, preferably 15min, and the range of tj3 is 3min~8min, preferably 4min~5min.

[0099] When the temperature in the barrel is lower than the set temperature, the target sterilization parameters can be directly determined according to the temperature in the barrel. This process is similar to the implementation method of determining the target sterilization parameters according to the temperature in the barrel in the previous example, and will not be repeated here.

[0100] In some embodiments, the drying and sterilization method also includes: during the execution of the sterilization program, the real-time sterilization parameters in the clothing treatment drum are also monitored, and the sterilization program is ended when the real-time ozone parameters reach the preset end conditions of the sterilization program; after the sterilization program is ended, the heating device and the air supply component are controlled to restart and continue to dry the clothes in the drum until the preset dryness conditions are reached; the real-time ozone parameters include real-time ozone concentration, and / or real-time ozone degradation time.

[0101] Specifically, during the execution of the sterilization program, ozone is introduced into the laundry treatment drum with target sterilization parameters. When the target sterilization parameters include target ozone concentration, target ozone-passing time, and target ozone degradation time, during the execution of the sterilization program, ozone of the target concentration is introduced into the laundry treatment drum, and after the target ozone-passing time is reached, ozone is stopped from being introduced into the laundry treatment drum, and the residual temperature in the drum is used to quickly degrade the remaining ozone.

[0102] After the target ozone degradation time is reached or the sterilization concentration in the clothing treatment drum is degraded to the qualified value, it means that the preset conditions for ending the sterilization program are met. At this time, the sterilization program is ended, and the air supply component and heating device are restarted to continue drying the clothes in the drum.

[0103] During the drying process, the inlet air temperature and the return air temperature are monitored, and the preset dryness judgment condition is determined to be met based on the temperature difference between the inlet air temperature and the return air temperature. If the temperature difference between the inlet air temperature and the return air temperature is less than or equal to the third temperature, it is determined that the preset dryness judgment condition is met, and the air supply component and the heating device are controlled to stop starting, and the entire drying process ends. If the temperature difference between the inlet air temperature and the return air temperature is greater than or equal to the third temperature, it is determined that the preset dryness judgment condition is not met, and the clothes continue to be dried. The third temperature is, for example, 5°C-10°C. In other achievable methods, it can also be determined that the preset dryness judgment condition is met based on the drying time reaching the set drying time.

[0104] In general, this embodiment turns off the heating components and the air supply components when the moisture content of the dried clothes is low, and then introduces ozone to sterilize the clothes. After stopping the introduction of ozone, the residual temperature in the drum is used to degrade the remaining ozone, which not only enhances the sterilization effect, but also minimizes the risk of ozone leakage exceeding the standard.

[0105] The drying and sterilization process of this embodiment is described in detail below.

[0106] Reference Figure 5 , after the user puts the clothes in through the clothes inlet, the drying and sterilization is started (process S01). Before drying the clothes, the wet clothes are weighed and the weighing gear is determined (process S02). Then, the overall drying time or the first drying time for starting ozone is preliminarily determined according to the weighing gear (process S03).

[0107] Then the heating device and the air supply component are started to provide high-temperature hot air into the drum to dry the clothes. At the same time, the clothes processing drum rotates at a certain rotation frequency, such as starting for 115s and stopping for 5s (the rotation frequency is not specifically limited) (process S04).

[0108] During the drying process, the air inlet temperature Tj and the return air outlet temperature Th are monitored. The air inlet is the inlet position where the air supply component blows dry hot air into the drum, and the return air outlet is the outlet position where the humid hot air in the drum flows from the drum into the air duct component. The temperature difference △T1 is obtained according to the air inlet temperature Tj and the return air outlet temperature Th (process S05).

[0109] It is determined whether ΔT1 satisfies ΔT1≤Ti1 (process S06), where Ti1 is a preset value, preferably 12-18°C.

[0110] If ΔT1≤Ti1 is not satisfied, the air inlet temperature Tj and the air return temperature Th are continuously monitored until ΔT≤Ti1 is satisfied. Alternatively, when the drying time reaches the first set time, ozone sterilization can be performed.

[0111] If ΔT1≤Ti1 is satisfied, it is determined that ozone can be introduced into the laundry treatment tub. Alternatively, when the drying time reaches the first set time, ozone sterilization can be used.

[0112] After determining that ozone can be introduced into the laundry treatment drum, the drum temperature Tn is detected (process S07), and it is determined whether the drum temperature Tn satisfies Tn≥Ti2 (process S08), where Ti2 is a preset value, which can be selected as 50-60°C, and preferably 55°C.

[0113] If Tn<Ti2, the target ozone concentration is determined to be C2, the target ozone passage time is tc2, and the target ozone degradation time is tj2 (process S12-S13).

[0114] If Tn≥Ti2 is satisfied, it is necessary to further determine whether Tn satisfies Tn≥Ti3 (process S09), where Ti3 is a preset value, which may be 60-65°C, preferably 65°C, and Ti2<Ti3.

[0115] If Tn<Ti3 is satisfied, the target ozone concentration is determined to be C1, the target ozone passage time is tc1, and the target ozone degradation time is tj1 (process S14-S15);

[0116] If Tn≥Ti3 is satisfied, the target ozone concentration is determined to be C3, the target ozone passage time is tc3, and the target ozone degradation time is tj3 (process S10~S11). Alternatively, when Tn≥Ti3 is satisfied, the target ozone concentration, target ozone passage time, and target ozone degradation time are further determined in combination with the initial weight of the clothes before drying. For example, when the initial weight of the clothes is 3kg-4kg, the target ozone concentration is determined to be C31, the target ozone passage time is tc31, and the target ozone degradation time is tj31; when the initial weight of the clothes is 5kg-6kg, the target ozone concentration is determined to be C32, the target ozone passage time is tc32, and the target ozone degradation time is tj32.

[0117] Among them: C2>C1>C3, tc2>tc1>tc3, tj2>tj1>tj3; C31<C32, tc31<tc32, tj31<tj32.

[0118] After determining the target ozone concentration, target ozone flow time, and target ozone degradation time, proceed to the next step. Turn off the air supply component and the heating component, stop blowing hot air (process S16), keep the barrel rotating, and introduce ozone of the target concentration into the barrel for sterilization (process S17). After reaching the target ozone flow time, stop introducing ozone, and use the higher residual temperature in the barrel to quickly degrade the remaining ozone (process S18).

[0119] After reaching the target ozone degradation time or the ozone concentration degradation reaches the qualified value, restart the air supply component and the heating device to continue drying the clothes (process S19). During the drying process, monitor the air inlet temperature Tj and the return air outlet temperature Th, and obtain the temperature difference △T2 based on the air inlet temperature Tj and the return air outlet temperature Th. Determine whether △T2 satisfies △T2≤Ti4 (process S20). If △T2≤Ti4 is satisfied, it means that the clothes have been completely dried and the entire drying and sterilization process is completed (process S21); if △T2>Ti4, it means that the clothes are not completely dried and continue to dry the clothes. Ti4 is a preset value, which can be preferably 5-10°C. Alternatively, when the drying time reaches the second set drying time, the clothes can be considered to be completely dried.
