[0047] The following will further describe the implementation manners of the present application in detail in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0048] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0049] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0050] In the embodiments of the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0051] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0052] In the related art, when washing plush toys, the washing machine disinfects and sterilizes the plush toys by heating the washing water for high-temperature disinfection and sterilization. Usually, fixed 60°C pasteurization or 90°C high-temperature disinfection is used. However, the sterilization effect on plush toys is poor.

[0053] On the other hand, some solutions sterilize the plush toys during the drying process, but usually use a single fixed high temperature for sterilization. The fixed high temperature may damage the material of the plush toys, affect their appearance and service life, and consume a large amount of energy during long-term high-temperature drying.

[0054] The embodiments of the present application provide a drying device, its control method, control device, and storage medium to solve the problem that the existing drying devices have poor sterilization effects on plush toys. The drying device can be a separate dryer or a washing and drying integrated device. The following will be combined with the attached Figures 1-5A description will be given.

[0055] According to an embodiment of the present application, with reference to Figure 1 as shown, the control method of the drying device includes:

[0056] S101: In response to a preset instruction, control the drying device to start to heat the gas in the drying cylinder.

[0057] Exemplarily, the preset instruction can be generated by the user operating the control panel of the drying device, and is generated after the user selects a specific drying program such as "plush toy drying", "high-temperature sterilization drying". It can also be that the drying device automatically generates a preset instruction in the drying stage after detecting that the object to be washed is a plush toy after washing.

[0058] The drying device can be an electric heating tube that directly heats the air, and the heated air enters the drying cylinder through the drying air duct; the drying device can also be a heat pump system that heats the air through the phase change cycle of the refrigerant. Optionally, the drying device can also adopt other heating elements, and this embodiment does not make specific limitations on this.

[0059] In an optional implementation manner, the drying device is provided with a condensation device. During the process of controlling the drying device to start to heat the drying cylinder, the method further includes: obtaining the real-time temperature; when the real-time temperature is less than the preset temperature threshold, controlling the condensation device to close; when the real-time temperature is greater than or equal to the preset temperature threshold, controlling the condensation device to start.

[0060] In this embodiment, during the heating process of the drying device, the real-time temperature of the drying cylinder is obtained through a temperature sensor. When the detected real-time temperature of the drying cylinder is less than the preset temperature threshold, it indicates that it is in the low-temperature stage at this time and rapid heating is required. The control system keeps the condensation device closed to avoid the condensation device starting in the low-temperature stage and thus affecting the heating speed, ensuring that the air and plush toys in the drying cylinder can be heated to the preset sterilization temperature range faster and shortening the overall drying time.

[0061] When the detected real-time temperature of the drying cylinder is greater than or equal to the preset temperature threshold, the control system starts the condensation device. At this time, the air temperature in the drying cylinder is high enough to start effectively evaporating the moisture in the plush toys and perform dehumidification.

[0062] Exemplarily, the preset temperature threshold can be 50°C - 55°C, such as 50°C, 53°C or 55°C.

[0063] Through the above control method, rapid heating can be achieved in the initial stage of heating, the time to reach the sterilization temperature and the drying temperature can be shortened, and the drying efficiency and quality of the plush toys can be improved.

[0064] Exemplarily, the condensing device may include a condensing pipe disposed in the drying air duct. By introducing cold water into the condensing pipe, the cold water can indirectly exchange heat with the hot air in the drying air duct. Since the temperature of the cold water is relatively low, it will absorb the heat in the hot air, causing the air temperature to drop, and the water vapor in the air will condense and precipitate accordingly, thereby achieving the purpose of dehumidification. The condensed water can be discharged through the drainage system.

[0065] S102: Obtain a plurality of target temperature ranges and the target duration corresponding to each target temperature range;

[0066] In this embodiment, the control system obtains preset parameters related to the current drying and sterilization program. The preset parameters include a plurality of target temperature ranges and the corresponding target durations, and these target temperature ranges can be set according to the temperature ranges required for inactivating different microorganisms (such as bacteria, viruses, mites and their eggs).

[0067] In an optional real-time manner, obtaining a plurality of target temperature ranges and the target duration corresponding to each target temperature range includes: obtaining the types of bacteria on the object to be washed; determining the target temperature range and the target duration based on a preset correspondence table and the types of bacteria, where the preset correspondence table represents the correspondence relationship among the types of bacteria, the target temperature range and the target duration.

[0068] Exemplarily, the types of bacteria can be selected by the user or the types of pollutants that the user may have (for example, no special, having stains, having an odor, having baby saliva, having pet contact, etc.). The system infers the possible types of bacteria according to the user input and in combination with the preset logic. It can also indirectly infer the possible types of bacteria by analyzing the stain components or odor characteristics through sensors (such as optical sensors, odor sensors, etc.) built in the drying device during the washing stage. It can also be that the drying device learns and infers the possible types of bacteria on the current object to be washed according to the user's past usage habits and the selected program.

[0069] Optionally, a preset correspondence table is stored inside the drying device. After determining the types of bacteria, the corresponding target temperature range and target duration can be determined by looking up the table, so as to be able to determine the temperature and time parameters during the drying process in a targeted manner, thereby achieving more accurate and effective sterilization drying.

[0070] S103: Control the drying cylinder to heat up to a plurality of target temperature ranges in sequence and maintain the target duration corresponding to each target temperature range.

[0071] In an optional embodiment, the above step S103 may include: controlling the drying cylinder to heat to a first target temperature range and maintaining for a first target duration; then, controlling the drying cylinder to heat to a second target temperature range and maintaining for a second target duration; then, controlling the drying cylinder to heat to a third target temperature range and maintaining for a third target duration; wherein, the first target temperature range is less than the second target temperature range, and the second target temperature range is less than the third target temperature range.

[0072] Relevant research data shows that 80% of plush toys carry harmful bacteria or viruses and need to be regularly cleaned with a washable cleaner and thoroughly dried. Common harmful microorganisms include: Escherichia coli, Staphylococcus aureus, mold, mites and eggs, viruses (such as norovirus, influenza virus), etc.

[0073] According to the recommendations of the World Health Organization or the Centers for Disease Control and Prevention, the temperature and time requirements for inactivating the above bacteria and viruses are: the sterilization requirements for Escherichia coli, Staphylococcus aureus, and mold are above 80°C for 20 minutes; the sterilization requirements for mites and eggs are above 60°C for 1 hour; the sterilization requirements for viruses (such as norovirus, influenza virus) are above 75°C for 30 minutes.

[0074] Therefore, optionally, based on the types of germs usually carried by plush toys, the first target temperature range in the above steps can be 65°C ± 5°C, the first target duration can be 1 hour, the second target temperature range can be 80°C ± 5°C, the second target duration can be 30 minutes, the third target temperature range can be 85°C ± 5°C, and the third target duration can be 20 minutes. Ensure as comprehensive disinfection and sterilization as possible for the types of germs usually carried by plush toys.

[0075] In this embodiment, optionally, the drying temperature control logic diagram of the drying equipment can refer to Figure 2 as shown, and multi-stage segmented temperature control is used to comprehensively sterilize plush toys.

[0076] In addition, during the heating and sterilization process of plush toys, the first target temperature range is less than the second target temperature range, and the second target temperature range is less than the third target temperature range, that is, the temperature during the heating process is gradually increased in segments, from the outside to the inside, from shallow to deep. On the one hand, the heating time is reduced and the heating efficiency is improved. On the other hand, comprehensive sterilization of plush toys is carried out, realizing more thorough, safer, and more efficient drying and sterilization of plush toys.

[0077] In another alternative embodiment, the above step S103 may include controlling the drying cylinder to heat to a first target temperature range and maintaining it for a first target duration. Controlling the drying cylinder to heat to a second target temperature range and maintaining it for a second target duration. Controlling the drying cylinder to heat to a third target temperature range and maintaining it for a third target duration. Wherein, the first target temperature range is less than the second target temperature range, and the second target temperature range is less than the third target temperature range. Wherein, there is no requirement for the order of the heating temperatures. For example, it can be heated to the second target temperature range first, then to the third target temperature range, and then the heating power of the drying device can be adjusted to adjust the temperature to the second temperature range. Further, a gas heating temperature order can also be adopted.

[0078] It can be understood that there are significant differences between plush toys and general clothing. The internal and external materials of plush toys are quite different. Usually, the external part may be various fibers, such as pure cotton, polyester fiber or blended materials, while the internal filling may include PP cotton, memory foam, down, etc. Different materials have an internal and external temperature difference during drying and sterilization and mite removal, resulting in the inability to completely eliminate the bacteria growing inside, affecting the sterilization effect of plush toys.

[0079] In an alternative embodiment, the drying device is provided with a variable-frequency vacuum pump. The variable-frequency vacuum pump is connected to the external air and the drying cylinder. The variable-frequency vacuum pump can evacuate or inflate the drying cylinder to create a negative pressure environment or a positive pressure environment inside the drying cylinder. The negative pressure pulsating air flow can significantly enhance the penetration ability of hot air into the internal filling of the plush toy. When in negative pressure, the difference inside and outside the plush toy causes the air in the gaps between the plush toy fibers and the filling to be pumped out; when in positive pressure, the high-temperature air flow is more easily pressed in and penetrates deeper into the toy interior, ensuring that the high-temperature air flow can more effectively contact and penetrate into the interior of the plush toy, ensuring that the internal and external temperatures of the plush toy are consistent, and ensuring that internal microorganisms (such as mites, mold spores, viruses) are completely inactivated at high temperatures, improving the sterilization effect of the plush toy and solving the problem of incomplete sterilization caused by the internal and external temperature difference in traditional drying.

[0080] Further, during the process of controlling the drying cylinder to heat to multiple target temperature ranges in sequence and maintaining the target duration corresponding to each target temperature range, refer to Figure 3 As shown, the control method further includes: controlling the variable-frequency vacuum pump to perform an evacuation action to extract the air inside the drying cylinder; controlling the variable-frequency vacuum pump to perform an inflation action to introduce air into the drying cylinder. Controlling the variable-frequency vacuum pump to repeatedly perform the evacuation action and the inflation action; after the operation duration of the variable-frequency vacuum pump reaches a first preset duration, controlling the variable-frequency vacuum pump to close.

[0081] In this embodiment, during the process of maintaining a certain target temperature range, the control system controls the variable-frequency vacuum pump to perform an air extraction operation, extracting part of the air in the drying cylinder to reduce the pressure inside the cylinder and form a negative pressure environment (for example, reaching about -10 kPa). Immediately or alternately, the control system will instruct the variable-frequency vacuum pump to perform an air inflation operation, introducing air (or mainly hot air after heating) into the drying cylinder to increase the pressure inside the cylinder and form a positive pressure environment (for example, reaching about +5 kPa). The air extraction and inflation are cyclically executed to form a hot air flow with alternating negative and positive pressures, achieving the purpose of high-temperature penetration inside the plush toy, thereby realizing the thorough elimination of germs and mites inside and outside the plush toy.

[0082] Optionally, the number of times of cyclic execution can be one or more, which can be specifically set according to needs.

[0083] In an alternative embodiment, the drying device is further provided with a steam generator, which is connected to the drying cylinder and used to convey high-temperature steam into the drying cylinder. The control method further includes: controlling the steam generator to be turned on during the operation of the variable-frequency vacuum pump; and controlling the steam generator to be turned off after the variable-frequency vacuum pump is turned off.

[0084] It can be understood that high-temperature steam not only has the characteristic of high-temperature sterilization (able to effectively kill bacteria, viruses, fungal spores, etc.), but also is a liquid itself, which can penetrate into the plush fibers and fillers to dissolve and remove some stubborn stains and allergens (such as dust mite excrement). The air extraction and inflation actions of the variable-frequency vacuum pump help to suck the high-temperature steam deeper into the toy, evenly distribute the steam and maintain a certain pressure, and at the same time can also take out or disperse the moisture generated after the steam condenses and the killed microorganisms.

[0085] Through the coordinated control of the variable-frequency vacuum pump and the steam generator, the sterilization effect on the inside of the plush toy can be improved, achieving a deeper cleaning, and it also has a good sterilization effect on plush toys with relatively dense fillers or more wrinkles.

[0086] According to experimental data, in an environment of steam above 100°C + negative pressure: conventional germs (such as Escherichia coli, influenza virus) can be inactivated within 10 - 20 seconds; stubborn microorganisms (mold spores, mite eggs) require 30 - 45 seconds; therefore, the first preset duration of the variable-frequency vacuum pump and the steam generator in this embodiment can be set to 1 minute to ensure sufficient sterilization while saving energy.

[0087] In other embodiments, the drying device can also be provided with an ultraviolet sterilization module to further sterilize the plush toy by combining ultraviolet rays to improve the sterilization effect.

[0088] In an alternative embodiment, the drying device includes a drying air duct, and a blower is disposed inside the drying air duct; after controlling the drying cylinder to be heated to a plurality of target temperature ranges in sequence and maintaining the target duration corresponding to each target temperature range, the method further includes: controlling the drying device to be turned off; controlling the blower to be turned on for a second preset duration.

[0089] In this embodiment, after the drying and disinfection are completed, the blower is turned on to perform natural air cooling on the plush toy, so that the plush toy is smoothly cooled from the high-temperature sterilization state to a temperature that is more suitable for touching. And the continuous air flow helps to take away the trace moisture that may remain on the surface of the toy, preventing the toy from getting wet due to sudden cooling or moisture condensation.

[0090] In an alternative embodiment, after controlling the drying cylinder to be heated to a plurality of target temperature ranges in sequence and maintaining the target duration corresponding to each target temperature range, the method further includes: obtaining the drying degree of the object to be washed, and in the case where the drying degree is less than or equal to a preset drying threshold, controlling the drying device to continue to be turned on for drying; in the case where the drying degree is greater than the preset drying threshold, controlling the drying device to be turned off.

[0091] Optionally, before and during drying, a high-precision weight sensor can be used to record the weight change of the plush toy. According to the weight reduction caused by water evaporation, combined with a preset drying degree threshold (for example, the weight reduction reaches 5% of the initial weight), it is judged whether the preset drying degree is reached. A humidity sensor is also installed inside the drying cylinder to monitor the air humidity inside the cylinder in real time. When the humidity drops to a preset threshold (for example, the relative humidity is lower than 10%) and remains for a period of time (for example, there is no significant change in humidity within 5 minutes), it is determined that the preset drying degree is reached.

[0092] If the detection result shows that the drying degree has not reached the preset value, the system automatically extends the preset drying reserved duration (for example, extends for 10 - 15 minutes) and continues drying. At the same time, according to the current temperature and humidity conditions, the drying parameters are adjusted (for example, the temperature is increased or the air volume is enhanced) to accelerate the drying process. If the detection result shows that the drying degree has reached the preset value, the system automatically turns off the drying device and enters the cooling stage (turns on the blower for air cooling) to prevent the toy from being damaged due to residual heat.

[0093] The control method of the drying device provided by the embodiment of the present application includes controlling the drying device to start in response to a preset instruction to heat the drying cylinder; obtaining a plurality of target temperature ranges and the target duration corresponding to each target temperature range; and controlling the drying cylinder to be heated to the plurality of target temperature ranges in sequence and maintaining the target duration corresponding to each target temperature range. After the washing is completed, the plush toy is heated to a high temperature by the drying device for drying and sterilization. In this process, the plush toy is controlled to be heated to a plurality of different target temperature ranges and the corresponding target duration is maintained to ensure that different types of bacteria or viruses can be effectively killed, improving the sterilization effect on the plush toy.

[0094] In a second aspect, the embodiment of the present application further provides a control device for a drying device. Referring to Figure 4 as shown, the control device includes:

[0095] A heating module 401, configured to control the drying device to start in response to a preset instruction to heat the gas in the drying cylinder;

[0096] An obtaining module 402, configured to obtain a plurality of target temperature ranges and the target duration corresponding to each target temperature range;

[0097] A control module 403, configured to control the drying cylinder to be heated to the plurality of target temperature ranges in sequence and maintain the target duration corresponding to each target temperature range.

[0098] The control device of the drying device in this embodiment can be applied to a drying device and execute the control method of the drying device in the above embodiment to improve the sterilization effect on the plush toy. The specific implementation manner may refer to the above embodiment, and this embodiment does not make specific limitations.

[0099] In a third aspect, the embodiment of the present application further provides a drying device, including a drying cylinder, a drying device, and a controller. The drying device is connected to the drying cylinder through a drying air duct; the controller is electrically connected to the drying cylinder and the drying device, and the controller is configured to execute the control method of the drying device in the above embodiment.

[0100] Optionally, the drying device may be a washing and drying integrated machine, a washing and drying set, or a separate dryer. The plush toy can also be extended to other items to be washed such as clothes, sheets, duvet covers, curtains, etc. This embodiment does not make specific limitations.
