[0049] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples provided are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. For example, although the steps of the method of the present invention are described in a specific order in this application, this order is not limiting. Those skilled in the art may perform the steps in a different order without departing from the basic principles of the present invention.

[0050] As shown in Figures 1 to 5, an embodiment of the present invention discloses a method for controlling fragrance retention in clothing, as shown in Figure 1, comprising:

[0051] Step S1, receiving a fragrance retention control instruction selected by a user;

[0052] Step S2, performing a fragrance retention operation on the clothes in the corresponding clothes processing stage according to the fragrance retention control instruction;

[0053] It should be noted that the control method of the present invention can selectively perform fragrance retention operations on clothes in the corresponding clothing processing stages according to the fragrance retention control instructions. The clothing processing stages corresponding to the fragrance retention control instructions selected by the user can be the last rinsing stage, the dehydration stage, the shaking stage after dehydration, and the cooling stage of the drying process. The user can thus choose to perform fragrance retention operations on clothes at different stages of the clothing processing process according to actual conditions.

[0054] In a preferred embodiment, the above-mentioned step S1 specifically includes: determining whether the user has selected the fragrance control instruction; if the determination result is no, prompting the user whether it is necessary to select the fragrance control instruction; if the determination result is yes, further determining whether the amount of fragrance in the fragrance agent delivery chamber is greater than or equal to the required amount of fragrance agent, if not, prompting the user to add fragrance agent.

[0055] The present invention can determine the corresponding amount of fragrance based on the fragrance level in the fragrance dispensing chamber, thereby reminding the user to add fragrance when the fragrance dispensing chamber is insufficient based on the required amount of fragrance. Therefore, the present invention has the functions of automatic detection and judgment and active reminder, which is more user-friendly and improves the user experience. The fragrance level can be detected by a reed switch level gauge or other detection device, which is not specifically limited by the present invention.

[0056] The fragrance control instructions of the present invention can correspond to different fragrance retention levels, including but not limited to fragrance control instructions for a slight fragrance mode, a light fragrance mode, and a strong fragrance mode; and the fragrance agent of the present invention includes one or more of a fragrance freshener with a fragrance retention function, a softener with a fragrance retention function, and a disinfectant with a fragrance retention function.

[0057] Example 1

[0058] In this embodiment, the clothing processing stage corresponding to the fragrance retention control instruction selected by the user is the last rinsing stage;

[0059] As shown in FIG2 , the method specifically includes: step S21 , adding and soaking the fragrance agent during the last rinsing process.

[0060] The laundry program generally includes washing, rinsing, and dehydration steps, wherein the number of rinsing is generally two. This embodiment is specifically performed during the last rinsing.

[0061] The above step S21 specifically includes: during the last rinsing process, flushing the required fragrance retaining agent into the outer tube, and completing the infiltration and fragrance retention as the rinsing action proceeds.

[0062] It should be noted that this embodiment utilizes a method of soaking and retaining fragrance during the final rinse phase, which can be adjusted to suit the different fragrance retention requirements of users. For example, the concentration, dosage, and soaking and retaining fragrance duration of the fragrance solution can be adjusted to ensure a good fragrance retention effect and enhance the user experience. Preferably, the water level for the final rinse can be lower than that for the normal rinse phase, and the soaking and retaining fragrance duration can be longer than that for the normal rinse phase, thereby achieving a better fragrance retention effect through a lower soaking water level and a longer soaking and retaining fragrance duration.

[0063] In a preferred embodiment, the clothing fragrance control method of this embodiment further includes: determining the amount of fragrance agent required to be administered and the required infiltration fragrance time according to clothing parameters and the fragrance control instruction selected by the user.

[0064] The clothing parameters may be the weight and / or material of the clothing, and the fragrance control instructions are fragrance mode instructions corresponding to different degrees of fragrance retention. Accordingly, the amount of fragrance agent required and the required soaking and fragrance retention time are determined based on the clothing material, clothing weight and fragrance mode instructions.

[0065] In a preferred embodiment, the step of "adding and soaking the fragrance agent during the last rinse" specifically includes: flushing the required fragrance agent into the outer barrel during the last rinse, and completing the soaking and fragrance retention as the rinsing action proceeds.

[0066] It should be noted that the present invention determines whether the infiltration and fragrance retention are completed in two ways: first, the infiltration and fragrance retention are completed with the completion of the rinsing step; second, according to the required infiltration and fragrance retention time, the infiltration and fragrance retention are completed when the required infiltration and fragrance retention time is reached; when the rinsing step is completed but the required infiltration and fragrance retention time is not reached, the time of the rinsing step needs to be extended to reach the required infiltration and fragrance retention time; when the required infiltration and fragrance retention time is reached but the rinsing step is not completed, the infiltration and fragrance retention needs to be completed with the completion of the rinsing step; the present invention can also set the time of the rinsing step according to the required infiltration and fragrance retention time.

[0067] In a preferred embodiment, the step of "flushing the required fragrance agent into the outer drum of the washing machine during the last rinse" specifically includes: flushing the required fragrance agent into the outer drum while the water is entering the last rinse.

[0068] This embodiment flushes the fragrance agent into the outer drum at the same time as the water is fed in for the last rinse, thereby reducing the time required for rinsing and soaking to retain the fragrance while achieving the fragrance retention effect. Moreover, the fragrance agent solution is fully dissolved during the flushing process into the drum, and the fragrance retention effect on the clothes is more uniform.

[0069] In a preferred technical solution, the step of "flushing the required fragrance into the outer drum during the last rinse" specifically includes: flushing the required fragrance into the outer drum after the last rinse is completed and the rinsing action begins.

[0070] In this embodiment, the fragrance solution is flushed and added after the last rinse is completed and the rinsing action begins. The concentration of the fragrance solution in the barrel gradually reaches the fragrance solution concentration corresponding to the fragrance control instruction as the fragrance solution is flushed and added. By flushing and adding the fragrance in this way, the fragrance retention step can be added after the last rinse is completed, thereby meeting the user's usage needs.

[0071] The present invention adopts a flushing method to fully dissolve the fragrance agent before it contacts the clothes, ensuring that the fragrance remains evenly on the clothes and has a good fragrance retention effect; and the motor can be controlled to rotate during each fragrance flushing process, that is, as the rinsing action proceeds, the clothes in the inner drum rotate and are evenly mixed with the flushed fragrance solution to achieve infiltration and fragrance retention.

[0072] In a preferred embodiment, the step of "flushing the required fragrance into the outer tube" specifically includes: determining the number of times the fragrance is added and the corresponding amount of flushing water for a single addition based on the amount of fragrance to be added; flushing the required fragrance into the outer tube according to the number of times the fragrance is added and the corresponding amount of flushing water for a single addition.

[0073] In a preferred embodiment, "determining the number of times the fragrance agent is dosed and the corresponding single flushing water volume based on the required amount of fragrance agent to be dosed" includes the following steps: presetting the single fragrance agent dosage, and obtaining the corresponding single flushing water volume based on the preset single fragrance agent dosage and the fragrance solution concentration; calculating the number of doses based on the required amount of fragrance agent and the preset single fragrance agent dosage; wherein the single fragrance solution concentration obtained based on the single flushing water volume and the preset single fragrance agent dosage is equal to the set fragrance solution concentration.

[0074] It should be noted that the present invention does not impose any restrictions on the control structure of the single fragrance delivery amount. Those skilled in the art can set it according to their needs. For example, the single fragrance delivery amount can be controlled by a valve, or a single fragrance delivery chamber can be added, and a siphon structure can be set in the single fragrance delivery chamber to achieve the quantitative delivery of the single fragrance.

[0075] In a preferred embodiment, the step of "flushing the desired fragrance into the outer tube" includes: flushing the desired fragrance into the outer tube through a flushing water channel.

[0076] The present invention can adopt a scheme of multiple flushing and adding fragrance agent. When there are many clothes that need to retain fragrance, multiple flushing and adding are adopted, and the concentration of the fragrance agent solution in a single flushing is the same as the set fragrance agent solution concentration, so that the fragrance agent is more uniform during the addition process and the fragrance retention effect is good; at the same time, the structure and shape of the flushing water channel can be specifically set to extend the flushing path. For example, the flushing water channel can be set to a spiral structure, or connected by segmented flushing water channels with different inclination degrees, so that the fragrance agent solution can be fully dissolved during the flushing process.

[0077] In a preferred embodiment, the method of this embodiment further includes: obtaining the water inlet temperature of the washing machine; obtaining the corresponding volatilization temperature according to the type of fragrance agent; and determining whether the rinse water needs to be heated according to the water inlet temperature and the volatilization temperature.

[0078] Among them, the step of "determining whether the rinsing water needs to be heated based on the inlet water temperature and the volatilization temperature" includes: determining whether the inlet water temperature is greater than or equal to the preset immersion temperature; if not, heating the inlet water of the washing machine so that the heated inlet water temperature is greater than or equal to the preset immersion temperature and less than the volatilization temperature.

[0079] The present invention detects and adjusts the temperature of the rinsing water for the fragrance agent. Raising the temperature of the rinsing water for the fragrance agent is beneficial to its diffusion and attachment to the clothing fibers during the infiltration process. At the same time, it is necessary to avoid excessively high temperature causing a large amount of volatilization of the fragrance agent solvent molecules and affecting the final fragrance effect. Therefore, the present invention can improve the fragrance effect by controlling the temperature of the rinsing water for the fragrance agent.

[0080] Example 2

[0081] In this embodiment, the clothing processing stage corresponding to the fragrance retention control instruction selected by the user is the dehydration stage;

[0082] As shown in FIG3 , the method specifically includes: step S22 , performing a fragrance-retaining operation on the clothes by spraying in the dehydration stage.

[0083] In a preferred technical solution, the above step S22 specifically includes: performing a preliminary dehydration step; performing a spraying and fragrance-retaining step; and performing a final dehydration step.

[0084] Before "performing the preliminary dehydration step", the control method of this embodiment also includes: determining whether the water absorption saturation of the clothes is less than or equal to a preset threshold value. If so, the spraying and fragrance retention step is directly executed; if not, the preliminary dehydration step is first executed, and when the water absorption saturation of the clothes after the preliminary dehydration is less than or equal to the preset threshold value, the spraying and fragrance retention step is executed.

[0085] This embodiment adopts a technical solution of spraying to retain fragrance during the dehydration stage, controls the water absorption saturation, i.e., the water absorption rate, of the clothes, and sprays a fragrance solution of adjusted concentration onto the clothes to retain fragrance, which can make the fragrance molecules evenly adhere to the fibers of the clothes, achieving a uniform fragrance retention effect; and this embodiment can adopt a solution of spraying while dehydrating, where the fragrance solution is sprayed onto the clothes and then dehydrated and discharged. In this process, the fragrance molecules adhere to the fibers of the clothes to retain fragrance, and the fragrance retention effect is uniform, the required fragrance retention time is short, and rapid fragrance retention can be achieved; the fragrance solution after dehydration can be recycled or directly discharged.

[0086] In a preferred embodiment, the step of "determining whether the water absorption saturation of the clothes is less than or equal to a preset threshold value" specifically includes: detecting the dry weight of the clothes and the weight after the last rinse and drainage, and calculating the water absorption saturation of the clothes based on this; and determining whether the calculated water absorption saturation of the clothes is less than or equal to a preset threshold value.

[0087] It can be understood that for different fragrance control instructions, the solubility of the corresponding fragrance solution is different, and the higher the water absorption saturation of the clothes, the higher the water content of the corresponding clothes. The water content of the clothes will reduce the concentration of the sprayed fragrance solution. It is necessary to reduce the water absorption saturation of the clothes accordingly to reduce the impact on the concentration of the fragrance solution in order to achieve the fragrance effect required by the user.

[0088] In a preferred embodiment, "performing a preliminary dehydration step" specifically includes: determining a dehydration speed and a dehydration time according to the material and / or weight of the clothes; controlling a drive motor to perform preliminary dehydration on the clothes according to the determined dehydration speed and dehydration time; and re-determining whether the water absorption saturation of the clothes is less than or equal to a preset threshold.

[0089] It is understandable that in the case of a large amount of clothes or clothes made of materials that are difficult to dehydrate, it is necessary to increase the speed of the initial dehydration and extend the time of the initial dehydration so that the water absorption saturation of the clothes after the initial dehydration is less than or equal to the preset threshold value; the purpose of the initial dehydration of the present invention is to avoid the influence of the high water content of the clothes on the fragrance retention effect of the clothes. In order to achieve the fragrance retention effect desired by the user, the concentration of the fragrance agent solution can be appropriately increased. By spraying the clothes with a certain water content with the fragrance agent solution with an increased concentration, the fragrance retention effect required by the user can be achieved.

[0090] In a preferred embodiment, "executing the spraying and fragrance retention step" specifically includes: determining the amount of fragrance solution required for spraying and fragrance retention according to the material and / or weight of the clothes; spraying the fragrance solution onto the surface of the clothes through a spraying device; and controlling the rotation of the drive motor during the spraying process.

[0091] The present invention can achieve a more uniform spraying effect and accelerate the spraying and soaking effect of clothes by controlling the rotation of the inner drum during the spraying process. It should be noted that the present invention does not limit the structure of the spraying device, as long as it can spray the fragrance solution onto the surface of the clothes.

[0092] In a preferred embodiment, when performing the spray fragrance retention function, the corresponding spray fragrance retention time is set according to the weight and / or material of the clothes. It is understandable that different spray fragrance retention times are set for different clothing weights and different clothing materials to achieve corresponding fragrance retention effects.

[0093] It should be noted that the larger the measured value of the corresponding clothing weight, the larger the amount of fragrance solution required and the longer the required spraying time. The present invention can pre-set standard values; for example, for a standard weight of clothing, the amount of fragrance solution required to spray until it is completely soaked and the spraying time required to achieve the desired fragrance retention level can be determined. Then, based on the ratio of the actual clothing weight to the standard weight, the actual required fragrance solution amount and spraying time can be calculated. Similarly, the required fragrance solution amount and spraying time can be adjusted accordingly based on the different water absorbency of the clothing material.

[0094] Moreover, the present invention can adopt a method of spraying while rotating, so that the fragrance solution sprayed onto the clothes is more uniform during the rotation process, thereby ensuring that the final fragrance effect is more uniform; when the rotation speed is relatively high, this process can also be understood as a scheme of spraying and dehydrating at the same time, that is, the fragrance solution sprayed onto the clothes is swung out through rotation after soaking the clothes. In this process, the fragrance molecules adhere to the surface of the clothes. The technical scheme of spraying and dehydrating at the same time can accelerate the fragrance retention process of the clothes, reduce the time required for spraying and retaining fragrance, and make the fragrance retention effect of the clothes more uniform.

[0095] The present invention can also adopt a method of alternating spraying and inner drum rotation. During spraying, the fragrance solution soaks the clothes and gradually penetrates the clothes. During the rotation of the inner drum, the position of the clothes changes, thereby achieving uniform spraying and fragrance retention.

[0096] In a preferred embodiment, "performing the final dehydration step" further includes: after the spraying and fragrance-retaining operation is completed, controlling the drive motor to perform the final dehydration step on the clothes according to the dehydration curve, and discharging the fragrance-retaining solution after the final dehydration through the drainage pipe.

[0097] After the clothes have been sprayed for the set fragrance retention time and have achieved the desired fragrance retention, they are then subjected to a final spin cycle according to the dehydration curve. This step is a standard step in the laundry cycle. The motor drives the inner drum and the clothes inside to rotate at high speed, extracting moisture from the clothes and achieving dehydration. Those skilled in the art can adjust the spin speed and time of the final spin cycle as needed.

[0098] The present invention can also dehydrate clothes according to the dehydration curve during the dehydration stage after rinsing and draining, and can perform a spraying and fragrance-retaining operation in the early or middle stage of dehydration, and complete the fragrance-retaining operation of clothes after dehydration is completed; the normal dehydration time can also be appropriately extended to ensure the effect of spraying and fragrance-retaining and the dryness of the clothes after final dehydration.

[0099] Example 3

[0100] In this embodiment, the clothing processing stage corresponding to the fragrance retention control instruction selected by the user is the shaking-out stage after dehydration;

[0101] As shown in FIG4 , the method specifically includes: step S23 , performing a fragrance-retaining operation on the clothes by adopting an atomizing method in the shaking-out stage after dehydration.

[0102] It should be noted that the shaking-out stage of the washing program is carried out after the last dehydration of the washing program. The present invention performs atomization and fragrance retention operations on the clothes according to the fragrance retention control instructions selected by the user during the shaking-out stage. It can be a fragrance retention solution that can be directly atomized, or a fragrance retention solution of corresponding concentration can be diluted and then atomized; and the present invention can perform atomization and fragrance retention immediately after the shaking-out starts, or perform atomization and fragrance retention in the middle stage of shaking-out. The clothes have been initially scattered at the beginning of the shaking-out stage, and the fragrance retention effect is more uniform at this time; and the present invention can perform atomization and fragrance retention while shaking, and can also perform shaking and atomization and fragrance retention alternately.

[0103] In a preferred embodiment, the method of this embodiment further includes: determining whether the atomization and fragrance retention operation is completed, and if so, sending a prompt message to the user.

[0104] It should be noted that the completion time of the atomization and fragrance retention operation and the shaking-out stage of the present invention can be completed at the same time, that is, the atomization and fragrance retention operation can be stopped at the end of the shaking-out stage; the shaking-out process can also be completed first and the atomization and fragrance retention can be completed later, or the atomization and fragrance retention can be completed first and the shaking-out process can be completed later; when both the atomization and fragrance retention steps are completed, a prompt message is sent to the user.

[0105] In a preferred embodiment, "using an atomization method to perform a fragrance retention operation on clothes during the shaking-out stage after dehydration" specifically includes: during the shaking-out stage after dehydration, atomizing the corresponding fragrance retention solution into gas through the atomization module; as the shaking-out process proceeds, the atomization module sprays gas to atomize and retain the fragrance on the clothes.

[0106] Before the atomizing module atomizes the fragrance solution, the fragrance solution has been adjusted to a concentration corresponding to the fragrance control instruction selected by the user, so that the fragrance effect required by the user can be achieved after atomization.

[0107] It should be noted that the atomizing module of the present invention includes an atomizing nozzle for spraying the fragrance solution. The present invention does not limit the specific range of the spraying of the atomizing module. For example, the atomizing module can perform uniform atomizing spraying on the entire range of the washing drum, or it can perform atomizing spraying on a certain range. The specific setting can be based on the position of the clothes and the actual fragrance effect, as long as the uniform fragrance effect can be achieved on all clothes through atomization.

[0108] In a preferred embodiment, "determining whether the atomization fragrance retention operation is completed" specifically includes: setting a corresponding atomization fragrance retention time according to the material and / or weight of the clothes; and determining whether the set atomization fragrance retention time has passed.

[0109] In a preferred embodiment, "determining whether the atomization and fragrance retention operation is completed" specifically includes: detecting the water absorption rate of the clothes during the atomization and fragrance retention process; and determining whether the water absorption rate of the clothes reaches a preset threshold.

[0110] When either the atomization fragrance retention time or the water absorption rate of the clothing reaches the set conditions, the atomization fragrance retention operation is determined to be complete. It is understandable that the present invention presets a threshold value for the water absorption rate of the clothing, where the water absorption rate of the clothing is calculated based on the dry weight of the clothing and the wet weight after atomization fragrance retention; one possible scenario is that after the set atomization fragrance retention time, the water absorption rate of the clothing has not reached the preset threshold value, in which case the atomization fragrance retention operation is determined to be complete; another possible scenario is that the water absorption rate of the clothing reaches the preset threshold value first, but has not yet reached the set atomization fragrance retention time. In this case, the atomization fragrance retention operation is also determined to be complete, and the set atomization fragrance retention time needs to be corrected to ensure that the clothing is not too wet after the set atomization fragrance retention time is reached.

[0111] In a preferred embodiment, the step of "setting the corresponding atomization fragrance retention time according to the material and / or weight of the clothes" specifically includes: determining the amount of fragrance solution required for atomization according to the material and / or weight of the clothes; and calculating the corresponding atomization fragrance retention time according to the required amount of fragrance solution and a preset atomization rate.

[0112] In a preferred embodiment, the step of "atomizing the fragrance solution into vapor through an atomization module" specifically includes: atomizing the corresponding fragrance solution into vapor through an atomization module using ultrasonic atomization.

[0113] In a preferred embodiment, the control method of this embodiment further includes: as the shaking process proceeds, the atomization module adjusts the atomization rate and / or the spray direction.

[0114] It should be noted that, during the process of shaking out the clothes, the driving motor is controlled to rotate forward and backward periodically. Under the action of the inertia force and gravity of the clothes, the position of the clothes changes to achieve shaking out, thereby improving the condition of the clothes sticking to the drum after dehydration and the entanglement of the clothes. The present invention can adjust the atomization direction according to the change of the position of the clothes during the shaking out process, so that the atomization direction of the atomizing nozzle is always toward the clothes, thereby improving the effect of atomization and fragrance retention. For example, as the shaking out action proceeds, the atomization direction of the atomizing nozzle can show a periodic change from the direction toward the clothes sticking to the drum wall to the direction toward the clothes sticking to the bottom of the drum. Specifically, in the process of rotating to stopping in the shaking out stage, the atomizing direction of the atomizing nozzle gradually turns from the direction toward the clothes sticking to the drum wall to the direction toward the clothes sticking to the bottom of the drum. In the process of stopping to rotating in the shaking out stage, the atomizing direction of the atomizing nozzle gradually turns from the direction toward the clothes sticking to the bottom of the drum to the direction toward the clothes sticking to the drum wall.

[0115] The atomizing nozzle of the present invention can also adopt different atomizing rates as the shaking process proceeds. A larger atomizing rate is required at the beginning of the shaking, and a smaller atomizing rate is required at the end of the shaking. Therefore, after the atomization is completed, the air humidity value in the washing drum is controlled within a certain range, avoiding the high air humidity in the drum when the user takes out the clothes, which affects the user's usage experience; specifically, the atomizing rate of the atomizing nozzle can be controlled to gradually decrease during the process from the beginning to the end of the shaking.

[0116] Example 4

[0117] In this embodiment, the clothing processing stage corresponding to the fragrance retention control instruction selected by the user is the drying stage, specifically the cooling stage of the drying process;

[0118] As shown in FIG5 , the method specifically includes: step S24 , adding fragrance retaining agent to perform fragrance retaining operation on clothes during the cooling stage of the drying process.

[0119] It should be noted that the temperature change curve of the drying process of the dryer includes a heating stage and a cooling stage. The heating stage is the stage from the beginning of the drying process to the reaching of the highest temperature, and the cooling stage is the stage from the reaching of the highest temperature to the end of the drying process. The present invention adds a fragrance retaining operation on the clothes during the cooling stage of the drying process. It should be understood that: during the stage from the reaching of the highest temperature to the end of the drying process, the fragrance retaining operation is achieved by adding a fragrance retaining agent. It can be understood that, corresponding to different addition methods, the temperature of the corresponding cooling stage of the drying process is different, so as to ensure that with the end of the drying process, the drying and fragrance retaining steps of the clothes are completed, thereby achieving the fragrance retaining effect required by the user.

[0120] In a preferred embodiment, the step of "adding fragrance agent to the clothes to retain fragrance during the cooling stage of the drying process" specifically includes: during the cooling stage of the drying process, when the corresponding temperature is reached, adding fragrance agent solution to the clothes to retain fragrance; as the drying process proceeds, the residual heat is used to evaporate the fragrance agent solution, so that the fragrance agent molecules are attached to the fibers of the clothes, thereby completing the fragrance retention operation of the clothes.

[0121] It should be noted that the added fragrance solution penetrates into the clothing fibers to achieve comprehensive and uniform fragrance retention on the clothes. The fragrance solution here includes corresponding solvent molecules and solute molecules. As the drying process proceeds, under the action of residual temperature, the solvent molecules of the fragrance solution, namely water molecules, evaporate, and the solute molecules, namely fragrance molecules, adhere to the clothing fibers. The fragrance retention effect of the clothes is specifically achieved through the fragrance molecules. The residual temperature here refers to the temperature and heat in the temperature range from the addition of the fragrance to the end of the drying process.

[0122] In a preferred embodiment, the step of "applying a fragrance solution to the clothing to leave fragrance when the corresponding temperature is reached" specifically includes: applying the fragrance solution directly to the clothing to leave fragrance when the corresponding temperature is reached. The corresponding temperature range is 70-55°C, with a preferred temperature range of 65-60°C. Within this temperature range, the fragrance solution applied directly to the clothing gradually dries as the drying process proceeds, and the fragrance molecules adhere to the clothing fibers, leaving fragrance on the clothing.

[0123] In a preferred embodiment, the step of "applying a fragrance solution to the clothing to fragrance it when the corresponding temperature is reached" specifically includes: when the corresponding temperature is reached, vaporizing the fragrance solution via an atomization module to fragrance the clothing. The atomization method herein corresponds to a temperature range of 50-40°C, preferably 50-45°C. At this temperature, the atomization is performed, and upon completion of the drying process, both the drying and fragrance preservation steps are complete.

[0124] In a preferred embodiment, the step of "vaporizing the fragrance solution through an atomization module to leave fragrance on the clothes" specifically includes: controlling the drive motor to shake the clothes; during the shaking process, using ultrasonic atomization through the atomization module to atomize the fragrance solution into a vapor to leave fragrance on the clothes.

[0125] It should be noted that, during the shaking process, the sticking and entanglement of the clothes to the barrel are improved, and as the shaking process proceeds, the position of the clothes changes. Atomizing and retaining fragrance during the shaking process can make the clothes fully and evenly scented; and the present invention can also adopt other atomizing and retaining fragrance methods.

[0126] In a preferred embodiment, the step of "using the residual heat to evaporate the fragrance solution as the drying process proceeds" specifically includes: closing the ventilation duct as the drying process proceeds, using the residual heat to evaporate the fragrance solution, so that the fragrance agent molecules adhere to the fibers of the clothing; after the set fragrance retention time, opening the ventilation duct, and completing the fragrance retention operation of the clothes as the drying process ends.

[0127] It should be noted that the fragrance effect of the fragrance agent is that the fragrance agent molecules are attached to the clothes. When people put on the clothes, the fragrance agent molecules slowly evaporate and have a fragrance effect. During the drying process, in order to avoid the excessive volatilization of the fragrance agent molecules in the process of utilizing the residual heat to evaporate the fragrance agent solution and affect the fragrance effect, the ventilation duct can be closed for a period of time after the fragrance agent solution is added to fragrance the clothes. Thereafter, the ventilation duct is opened to discharge moisture, and the fragrance retention and drying steps of the clothes are completed until the drying process is completed. In addition, the steps of closing the duct and opening the duct of the present invention can be performed alternately, or according to a certain cycle, or the time for closing the duct to retain the fragrance can be increased in the early stage, and the time for opening the duct to exhaust air can be increased in the later stage, as long as it can be ensured that the fragrance effect and the drying of the clothes can be completed as the drying process proceeds.

[0128] The present invention achieves the retention of fragrance on clothes during the drying process. Specifically, in the stage from the highest temperature to the end of drying during the drying process, a fragrance agent is added at the corresponding temperature to retain the fragrance on the clothes. It can be understood that the fragrance on the clothes can also be achieved by adding a fragrance agent from the beginning of the drying process to the stage from the highest temperature to the end of drying, but it is necessary to ensure that the temperature is not too high during the heating process to affect the fragrance effect. In the cooling stage of the drying process, the clothes have been dried in the early stage of the drying process, and the humidity of the clothes has been reduced. At this time, the fragrance agent is added to retain the fragrance. First, it is convenient to control the temperature, and second, the fragrance effect is better. Third, it can avoid the fragrance lasting too long during the drying process, which will cause more volatilization of the fragrance agent molecules to affect the final fragrance effect.

[0129] One possible scenario is that the maximum temperature during the drying process is relatively low, meaning it's within the appropriate temperature range for applying fragrance spray. In this case, applying fragrance spray during either the warming or cooling phase of the drying process is acceptable, though applying it during the cooling phase will achieve a better fragrance retention effect. Another possible scenario is that when there are many clothes in the dryer drum, the fragrance needs to last longer. In this case, applying fragrance spray earlier in the drying process can be done while ensuring that the maximum temperature does not affect the fragrance retention effect.

[0130] The present invention has different delivery times corresponding to different delivery methods of the fragrance agent. When direct delivery is adopted, the temperature of the corresponding cooling stage of the drying process is higher; when atomization delivery is adopted, the temperature of the corresponding cooling stage of the drying process is lower. It can be understood that the present invention can also adopt other delivery methods of the fragrance agent, such as spray delivery, and the temperature of the corresponding cooling stage of the drying process is between the temperatures corresponding to the above two methods.

[0131] The present invention can detect the dryness of clothes and the air humidity in the drying drum after drying. When the detection result does not meet the requirements, the drying process time is appropriately increased. When the detection result meets the requirements, it is determined that the drying and fragrance retention operations are completed.

[0132] The temperature change from the time the fragrance retention agent is added to the end of drying during the cooling stage of the present invention can be that the temperature gradually decreases during the cooling stage, or a constant temperature is maintained for a stage, that is, the cooling stage of the drying process of the present invention is the stage from the time the highest temperature is reached to the end of drying, that is, the cooling stage of the drying process can also include a constant temperature stage after the temperature is raised to the highest temperature and a cooling stage after the constant temperature.

[0133] An embodiment of the present invention further provides a storage medium on which a computer program is stored, and the computer program is executed by a processor to implement the above-mentioned method for controlling the fragrance retention of clothing.

[0134] An embodiment of the present invention further provides a clothing processing device, to which the above-mentioned clothing fragrance control method is applied; the clothing processing device here can be a drying machine, a washing machine, a dryer, etc.
