Description

Technical Field

[0001] This application relates to the field of fabric drying technology, and more specifically, to a drying method, control device, and fabric processing equipment with drying function for a fabric processing device. Background Technology

[0002] Current drying equipment typically improves drying efficiency and shortens drying time by adjusting the compressor's target frequency. However, the actual drying time often doesn't perfectly match the time displayed on the equipment. This results in users not being able to obtain their fabrics at the desired time; drying too early causes wrinkles in the drum, while drying too late delays use. In certain situations, users need to use their fabrics at a very precise time, requiring a timed drying mode. However, current timed drying modes are essentially the same as other modes, only guaranteeing drying to end at the set time, not ensuring the drying effect, and easily leading to over-drying or under-drying. Summary of the Invention

[0003] This application provides a drying method, control device, and fabric processing equipment with drying function for fabric processing equipment, so as to at least solve the technical problem of fabrics not being dried or over-dried in the timed drying mode of current drying equipment.

[0004] According to a first aspect of the embodiments of this application, a drying method for a fabric treatment apparatus is provided, the drying method comprising:

[0005] Before entering the drying process, fabric property information is obtained, including at least the first fabric weight before entering the drying process;

[0006] The drying parameters during the drying process are controlled based on the target drying time and the fabric property information, and the drying parameters include at least the target frequency of the compressor.

[0007] In this embodiment, the drying parameters during the drying process are adjusted according to the user-set target drying time and fabric attribute information including at least the weight of the first fabric before entering the drying process. This allows for control of the moisture content and temperature inside the drying drum, ensuring that the fabric is just dry after the target drying time is reached, avoiding over-drying or under-drying situations, and improving the user experience.

[0008] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the drying time range to which the target drying time belongs, the fabric weight range to which the first fabric weight belongs, and the target frequency of the compressor have a first correspondence relationship. In the first correspondence relationship, the target frequency of the compressor corresponding to the drying time range with a longer drying time is smaller, and the target frequency of the compressor corresponding to the fabric weight range with a larger first fabric weight is larger.

[0009] The method of controlling the drying parameters during the drying process based on the target drying time and the fabric attribute information includes: determining the target frequency of the compressor according to the first correspondence before entering the drying process;

[0010] During the drying process, the compressor is controlled to operate at the target frequency.

[0011] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the drying method further includes:

[0012] Determine the dehydration speed of the fabric treatment drum before it enters the drying cycle based on the target drying time;

[0013] If the target drying time is longer than the set time, the fabric treatment drum is controlled to dehydrate at a first rotation speed before entering the drying cycle;

[0014] If the target drying time is less than or equal to the set time, the fabric treatment drum is controlled to dehydrate at a second speed before entering the drying cycle, where the first speed is less than the second speed.

[0015] The weight of the first fabric is the weight of the fabric after dehydration before entering the drying process.

[0016] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the drying method further includes:

[0017] During the fabric drying process, the inlet and outlet air temperatures of the fabric treatment drum are obtained.

[0018] If the temperature difference between the inlet air temperature and the outlet air temperature is greater than the set frequency adjustment temperature difference, and the number of times the temperature difference is greater than the set frequency adjustment temperature difference reaches a set number consecutively, the target frequency of the compressor is increased.

[0019] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the set frequency modulation temperature difference, the set number of times, and the fabric weight range to which the weight of the first fabric belongs have a preset correspondence;

[0020] The larger the fabric weight, the greater the set frequency temperature difference corresponding to the fabric weight range, and the fewer the set times corresponding to the fabric weight range.

[0021] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the drying method further includes:

[0022] Before the fabric drying time reaches the target drying time, it is also determined whether the drying condition is met.

[0023] When the drying conditions are met, the target frequency of the compressor is also adjusted according to the weight of the second fabric during the drying process;

[0024] Control the compressor to operate at the adjusted frequency for the remaining drying time.

[0025] In conjunction with the first aspect, in an optional implementation of the embodiments of this application, the fabric weight range to which the second fabric weight belongs has a second correspondence with the target frequency of the compressor. In the second correspondence, the target frequency of the compressor corresponding to the fabric weight range with a larger second fabric weight is smaller. Under the same fabric weight, the target frequency of the compressor in the first correspondence is greater than the target frequency of the compressor in the second correspondence.

[0026] When the drying conditions are met, adjusting the target frequency of the compressor according to the weight of the second fabric during the drying process includes: adjusting the target frequency of the compressor according to the second correspondence.

[0027] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the following method is used to determine whether the fabric has reached the dryness test condition:

[0028] The drying temperature difference and the number of drying cycles are determined based on the weight of the first fabric.

[0029] Obtain the inlet and outlet air temperatures of the fabric treatment cylinder;

[0030] If the temperature difference between the inlet air temperature and the outlet air temperature reaches the dryness-judging temperature difference, and the number of times the dryness-judging temperature difference is reached reaches the dryness-judging number, then the dryness-judging condition is determined to be met.

[0031] In conjunction with the first aspect, in one optional implementation of the embodiments of this application, the fabric weight range to which the first fabric weight belongs, the drying temperature difference, and the number of drying tests have a preset correspondence;

[0032] Among them, the larger the fabric weight, the smaller the temperature difference corresponding to the drying process.

[0033] The larger the fabric weight, the more times the fabric needs to be dried.

[0034] According to a second aspect of the present application, a control device is provided, which includes one or more processors and a non-transitory computer-readable storage medium storing program instructions. When the one or more processors execute the program instructions, the one or more processors are used to implement the drying method provided in the first aspect of the present application.

[0035] According to a third aspect of the present application, a fabric treatment apparatus is provided, which employs the drying method provided in the first aspect of the present application, or has a control device provided in the second aspect of the present application.

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0043] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0044] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0045] Because the current timed drying mode of drying equipment can only guarantee that the drying will end at the set time, without judging the dryness of the fabric, it only controls the drying time unilaterally, so there may be cases of over-drying or under-drying.

[0046] To address the above technical problems, this application provides a drying method, control device, and fabric processing equipment with drying function for fabric processing equipment. The drying method includes:

[0047] Obtain fabric property information, which includes at least the weight of the first fabric before it enters the dryer.

[0048] The drying parameters during the drying process are controlled based on the target drying time and fabric property information. The drying parameters include at least the target frequency of the compressor.

[0049] This embodiment adjusts the drying parameters during the drying process based on the user-set target drying time and fabric attribute information, including at least the weight of the first fabric before entering the drying chamber. This enables control over the moisture content and temperature inside the drum during the drying process, ensuring that the fabric reaches the target drying time and avoids over-drying or under-drying, thus improving the user experience.

[0050] First, a brief introduction will be given to the implementing entities of the embodiments of this application.

[0051] The drying method of this embodiment is applied to a fabric processing device with a drying function. The fabric processing device may have only a drying function, or it may have both a washing function and a drying function.

[0052] The fabric processing equipment includes a housing, an outer cylinder, and a fabric processing cylinder. The outer cylinder is housed within the housing, and the fabric processing cylinder is rotatably housed within the outer cylinder. The outer cylinder has an air outlet on its wall, and the fabric processing cylinder has a door seal at its opening with an air inlet at the door seal. The fabric processing cylinder has multiple flow holes on its wall, allowing airflow and / or water flow between the outer cylinder and the fabric processing cylinder.

[0053] The fabric processing equipment also includes an air duct assembly, which is disposed in the space between the housing and the outer cylinder, preferably above the outer cylinder. The air duct assembly includes an inlet air duct, an outlet air duct, and a fan. The outlet air duct connects the outlet to the inlet of the fan, and the inlet air duct connects the outlet of the fan to the inlet.

[0054] The fabric treatment equipment also includes a heat pump assembly for dehumidifying the airflow within the duct assembly. The heat pump assembly includes a compressor, evaporator, throttling device, and condenser. The compressor is located in the space between the housing and the outer cylinder, preferably at the bottom of the outer cylinder. The evaporator and condenser are integrated into a two-evapor housing located between the fan and the air inlet duct, with the condenser positioned close to the air inlet duct. The compressor, condenser, throttling device, and evaporator are connected sequentially to form a refrigerant circulation loop.

[0055] During the fabric drying process, under the action of the fan, the hot and humid airflow entering the air duct assembly is blown towards the evaporator. After absorbing heat and condensing in the evaporator, it forms dry and cold air. The dry and cold air is then heated by the condenser to form a high-temperature airflow, which finally enters the fabric processing drum to dry the fabric inside. When the heat pump assembly is on, the compressor is in the start-up state to allow the refrigerant to circulate in the refrigerant circulation path.

[0056] The fabric processing equipment also includes a first temperature detection device and a second temperature detection device. The first temperature detection device is located at the air inlet of the fabric processing cylinder and is used to detect the air inlet temperature of the fabric processing cylinder. The second temperature detection device is located at the air outlet of the fabric processing cylinder and is used to detect the air outlet temperature of the fabric processing cylinder.

[0057] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following implementation methods and examples can be combined with each other.

[0058] This embodiment proposes a drying method for fabric processing equipment, referring to... Figure 1 The flowchart shows the drying method, which includes the following steps:

[0059] S11. Before entering the drying process, obtain fabric property information.

[0060] Specifically, before starting the drying process, the fabric processing equipment with a drying function acquires the fabric attribute information. This information includes at least the weight of the first fabric before drying begins; that is, the weight of the wet fabric before drying starts. The first fabric weight can be obtained by direct weighing or calculated based on the motor current value; no specific limitation is made here.

[0061] It should be noted that, in this embodiment, "before entering the drying process" refers to the period before the drying airflow is introduced into the fabric treatment cylinder.

[0062] In one example, the fabric undergoes a washing cycle before entering a drying cycle. The first fabric weight is obtained by weighing the fabric after the dehydration stage of the washing cycle and before entering the drying cycle. In another example, the drying cycle includes a dehydration stage and a drying stage executed sequentially. After the user starts the drying cycle, the dehydration stage is executed first. The first fabric weight is obtained by weighing the fabric after the dehydration stage ends and before entering the drying stage.

[0063] In other possible implementations, the first fabric weight can also be the weight of a wet fabric that has not undergone dehydration, and no specific limitation is made here. Furthermore, the first and second fabric weights described in this application are not a distinction between different fabrics, but rather a distinction between the weights of fabrics obtained at different stages.

[0064] S12. Control the drying parameters during the drying process based on the target drying time and fabric property information. The drying parameters shall include at least the target frequency of the compressor.

[0065] Specifically, before starting the drying program, the user determines the target drying time based on their needs, or the user determines the target drying time by starting a timed drying mode. The target drying time is the time the user requires the fabric processing equipment to complete the drying process within this specified time. After determining the target drying time, upon receiving the user's control command to start drying, the target drying time is combined with the fabric attribute information to control the drying parameters during the drying process. This controls the fabric's moisture content and drying temperature to ensure that the fabric is dry when the target drying time is reached, without being over-dryed or under-dryed, thus guaranteeing the drying effect.

[0066] The drying parameters include at least the target frequency of the compressor.

[0067] In one example, the drying time range to which the target drying time belongs, the fabric weight range to which the first fabric weight belongs, and the target frequency of the compressor have a first correspondence. In the first correspondence, the target frequency of the compressor corresponding to the drying time range with a longer drying time is smaller, and the target frequency of the compressor corresponding to the fabric weight range with a larger first fabric weight is larger.

[0068] This is because, for the same target drying time, a larger initial fabric weight means more fabric in the drum, thus requiring a higher target compressor frequency. Conversely, for the same target drying time, a smaller initial fabric weight means less fabric in the drum, thus requiring a lower target compressor frequency. Furthermore, for the same initial fabric weight, a shorter target drying time requires a higher drum drying temperature, thus requiring a higher compressor frequency; conversely, for the same initial fabric weight, a longer target drying time requires a lower drum drying temperature, thus requiring a lower compressor frequency.

[0069] Controlling drying parameters during the drying process based on target drying time and fabric property information includes: determining the target frequency of the compressor according to a first correspondence before entering the drying process, and controlling the compressor to operate at the target frequency during the drying process.

[0070] Referring to the first correspondence table in Table 1 below, once the target drying time and the weight of the first fabric are determined, the target frequency of the compressor can be obtained by looking up the table. During the drying process, the compressor is controlled to operate at the target frequency determined by looking up the table.

[0071] Table 1:

[0072]

[0073] In Table 1, the size relationships of the target duration ranges are: Time3 > Time2 > Time1; the size relationships of the fabric weight ranges to which the second fabric weight belongs are: Weight3 > Weight2 > Weight1; and the size relationships of the target frequencies of the compressors are: Fre3 > Fre2 > Fre1, Fre6 > Fre5 > Fre4, Fre9 > Fre8 > Fre7, Fre1 > Fre4 > Fre7, Fre2 > Fre5 > Fre8, and Fre3 > Fre6 > Fre9.

[0074] In other possible implementation methods, drying parameters may also include fan speed, fabric processing drum speed, etc. Similarly, the fan speed (or fabric processing drum speed) can be determined according to the correspondence between the drying time range to which the target drying time belongs, the fabric weight range to which the first fabric weight belongs, and the fan speed (or fabric processing drum speed). The longer the drying time range, the smaller the fan speed (or fabric processing drum speed) corresponding to it, and the larger the fabric weight range, the larger the fan speed (or fabric processing drum speed) corresponding to it.

[0075] In one optional implementation, the drying method further includes: determining the dehydration speed of the fabric processing drum before entering the drying process, based on the target drying time. If the target drying time is longer than a set time, the fabric processing drum is controlled to dehydrate at a first speed before entering the drying process; if the target drying time is less than or equal to the set time, the fabric processing drum is controlled to dehydrate at a second speed before entering the drying process, wherein the first speed is less than the second speed; wherein the first fabric weight is the weight of the fabric after dehydration before entering the drying process.

[0076] This embodiment controls the dehydration speed before drying based on the target drying time, thereby effectively controlling the moisture content of the fabric before drying and preventing the fabric from being too dry or not dry after the target drying time is reached. For example, if the target drying time is set to 1 hour, the dehydration speed is ≤1000 rpm if the target drying time is >1 hour, and >1000 rpm if the target drying time is ≤1 hour.

[0077] In this embodiment, dehydration can be performed after the user starts the drying program but before the drying process begins (i.e., before the drying airflow is introduced into the fabric treatment drum). This is suitable for situations where the washing and drying programs are performed in two independent fabric treatment devices. Alternatively, dehydration can be performed during the dehydration phase of the washing program. This is suitable for washer-dryer combos. When the user selects the "wash + dry" program, the target drying time for the drying program must be determined. After determining the target drying time, the dehydration speed for the dehydration phase of the washing program is determined based on the target drying time, and dehydration is performed at the determined dehydration speed during the dehydration phase of the washing program.

[0078] This embodiment determines the dehydration speed based on the target drying time to regulate the moisture content of the fabric before it enters the drying process, thereby further ensuring the drying effect of the fabric when the target drying time is reached.

[0079] In other possible implementations, if the user sets a dehydration speed before entering the drying process, the dehydration is performed directly at the user-set dehydration speed before entering the drying process.

[0080] In one alternative implementation, refer to Figure 2 The flowchart shows that the drying method also includes the following steps:

[0081] S21. During the fabric drying process, obtain the inlet and outlet air temperatures of the fabric treatment drum.

[0082] S22. When the temperature difference between the inlet air temperature and the outlet air temperature is greater than the set frequency adjustment temperature difference, and the number of times the temperature difference is greater than the set frequency adjustment temperature difference reaches the set number of consecutive times, the target frequency of the compressor is increased.

[0083] Specifically, after determining the compressor operating frequency based on the user-set target drying time and the weight of the first fabric, the compressor operates at the target frequency after the drying process begins. Since the fabric weight changes continuously during drying, to further ensure the drying effect when the target drying time is achieved, the inlet and outlet air temperatures are acquired in real-time or periodically during the drying process. The compressor's target frequency is adjusted based on the temperature difference between the inlet and outlet air temperatures to adapt to changes in fabric weight.

[0084] After determining the temperature difference between the inlet and outlet air temperatures, if the temperature difference between the inlet and outlet air temperatures is greater than the set frequency adjustment temperature difference, and the number of times the temperature difference is greater than the set frequency adjustment temperature difference reaches the set number consecutively, it indicates that the temperature rise efficiency is slow. When the target drying time is reached, the fabric may not be dry. In this case, the target frequency of the compressor should be appropriately increased, for example, by increasing the target frequency of the compressor by the set value, or by increasing the target frequency of the compressor by one level.

[0085] If the temperature difference between the inlet and outlet air temperatures is less than or equal to the set frequency adjustment temperature difference, or if the temperature difference between the inlet and outlet air temperatures is greater than the set frequency adjustment temperature difference, and the number of times it exceeds the set frequency adjustment temperature difference has not reached the set number, then the target frequency of the compressor will not be adjusted.

[0086] After the compressor's target frequency is increased, the inlet and outlet air temperatures need to be acquired again in real time or periodically. The target frequency of the compressor is increased by reaching the set frequency adjustment temperature difference based on the newly acquired temperature difference between the inlet and outlet air temperatures, and the set frequency adjustment temperature difference is reached a set number of times. Once the compressor's target frequency is increased to the maximum operating frequency that can ensure the compressor's normal operation, the target frequency of the compressor is no longer increased. The drying process can be accelerated by increasing the fan speed and the speed of the fabric processing drum during the drying process.

[0087] In one optional implementation, the set frequency modulation temperature difference, the set number of times, and the fabric weight range to which the first fabric weight belongs have a preset correspondence; the larger the fabric weight range of the first fabric weight, the larger the set frequency modulation temperature difference, and the smaller the set number of times corresponding to the fabric weight range of the first fabric weight.

[0088] This is because heavier fabrics are more difficult to dry. Therefore, a larger set frequency adjustment temperature difference and a smaller number of setting cycles are needed to adjust the compressor's target frequency to avoid the fabric being incompletely dried after reaching the target drying time. Similarly, lighter fabrics are easier to dry. Therefore, a smaller set frequency adjustment temperature difference and a larger number of setting cycles are needed to adjust the compressor's target frequency to avoid the fabric being over-dried after reaching the target drying time.

[0089] Referring to the correspondence between the set frequency adjustment temperature difference, the number of times set, and the fabric weight range to which the first fabric weight belongs in Table 2 below, once the weight of the first fabric is determined, the corresponding set frequency adjustment temperature difference and the number of times set can be obtained by looking up the table.

[0090] Table 2:

[0091] First fabric weight Setting frequency modulation temperature difference Set number of times Weight1 Temp4 Times4 Weight2 Temp5 Times5 Weight3 Temp6 Times6

[0092] In Table 2, the relationship between the weight range of the first fabric and the weight range of the fabric is: Weight3 > Weight2 > Weight1. The relationship between the set frequency modulation temperature difference is: Temp6 > Temp5 > Temp4. The relationship between the set times is: Times4 > Times5 > Times6.

[0093] In one alternative implementation, refer to Figure 3 The flowchart shows that the drying method also includes the following steps:

[0094] S31. Before the fabric drying time reaches the target drying time, it is also determined whether the drying conditions are met.

[0095] S32. When the drying conditions are met, the target frequency of the compressor is also adjusted according to the weight of the second fabric during the drying process.

[0096] S33. Control the compressor to run at the adjusted frequency for the remaining drying time.

[0097] Specifically, during the drying process, the fabric is assessed in real time to determine whether it has met the drying criteria. If the fabric has met the drying criteria before reaching the target drying time, it indicates that the fabric is close to being dry. At this point, the target frequency of the compressor needs to be adjusted based on the weight of the second piece of fabric during the drying process to avoid over-drying the fabric after reaching the target drying time, and also to prevent the fabric from wrinkling inside the drum due to premature drying.

[0098] The second fabric weight is the weight of the fabric measured in real time after the drying airflow is introduced into the fabric treatment drum. As the drying process proceeds, the second fabric weight shows a continuous decreasing trend.

[0099] For example, there is a second correspondence between the fabric weight range to which the second fabric weight belongs and the target frequency of the compressor. In this second correspondence, the larger the fabric weight range of the second fabric, the lower the target frequency of the compressor. This is because the larger the second fabric weight, the higher the frequency at which the compressor continues to run after the initial drying is completed, ensuring a relatively stable temperature inside the drum and preventing wrinkles from forming inside the drum after the fabric cools. By ensuring that the fabric is just dried when the target drying time is reached, over-drying or under-drying is prevented.

[0100] In this system, for the same fabric weight, the target frequency of the compressor in the first correspondence is higher than that in the second correspondence. Under the same fabric weight, the compressor operates at a relatively higher target frequency when the drying process begins to avoid the fabric being undried when the target drying time is reached. Conversely, under the same fabric weight, a relatively lower target frequency is used when the drying condition is met to avoid the fabric being over-dried when the target drying time is reached.

[0101] When the drying conditions are met, the target frequency of the compressor is adjusted according to the weight of the second fabric during the drying process, including: adjusting the target frequency of the compressor according to the second correspondence.

[0102] Referring to Table 3 below, which shows the correspondence between the weight range of the second fabric and the target frequency of the compressor, once the weight of the second fabric is determined, the corresponding target frequency of the compressor can be obtained by looking up the table. During the drying process, the compressor is controlled to operate at this target frequency.

[0103] Table 3:

[0104]

[0105] In Table 3, the relationship between the weight ranges of the second fabric and the target frequency of the compressor is: Weight3 > Weight2 > Weight1.

[0106] In one alternative implementation, refer to Figure 4 The flowchart shows the steps to determine whether the judgment condition has been met:

[0107] S41. Determine the drying temperature difference and the number of drying cycles based on the weight of the first fabric.

[0108] S42. Obtain the inlet and outlet air temperatures of the fabric treatment cylinder;

[0109] S43. When the temperature difference between the inlet air temperature and the outlet air temperature reaches the dryness-judging temperature difference, and the number of times the dryness-judging temperature difference is reached reaches the number of dryness-judging times, the dryness-judging condition is determined to be met.

[0110] Specifically, before entering the drying process, the initial drying temperature difference and the number of drying cycles are determined based on the obtained initial fabric weight. In one example, the fabric weight range to which the initial fabric weight belongs, the initial drying temperature difference, and the number of drying cycles have a preset correspondence. A larger initial fabric weight corresponds to a smaller initial drying temperature difference and a higher number of drying cycles. This is because a larger initial fabric weight indicates greater difficulty in drying, requiring a smaller initial drying temperature difference and a higher number of drying cycles to ensure the fabric is relatively dry when the initial drying conditions are met, thus preventing the fabric from being undried when the target drying time is reached. Conversely, a smaller initial fabric weight indicates greater ease of drying, requiring a larger initial drying temperature difference and a lower number of drying cycles to prevent the fabric from becoming over-dry.

[0111] During the fabric drying process, the inlet and outlet air temperatures of the fabric processing drum are acquired in real time or periodically. The fabric is then judged according to the temperature difference and number of judgments determined based on the weight of the first fabric. When the temperature difference between the inlet and outlet air temperatures reaches the temperature difference for judgment and the number of times the temperature difference for judgment is reached reaches the number of judgments, the fabric is determined to be in a relatively dry state. Thus, when the target drying time is reached, the fabric is just the right amount of dry, and there will be no situation where the fabric is over-dry or under-dry.

[0112] Referring to Table 4 below, which shows the correspondence between the weight range of the first fabric, the drying temperature difference, and the number of drying tests, once the weight of the first fabric is determined, the corresponding drying temperature difference and number of drying tests can be obtained by looking up the table. During the drying process, drying is performed according to the determined drying temperature difference and number of drying tests.

[0113] Table 4:

[0114] First fabric weight Drying temperature Number of times of judgment Weight1 Temp1 Times1 Weight2 Temp2 Times2 Weight3 Temp3 Times3

[0115] In Table 4, the relationship between the weight range of the first fabric and the weight range of the fabric is: Weight3 > Weight2 > Weight1; the relationship between the drying temperature is: Temp3 < Temp2 < Temp1; and the relationship between the number of drying times is: Times3 > Times2 > Times1.

[0116] In one specific implementation of the embodiments of this application, reference is made to Figure 5 The flowchart illustrates the fabric drying method, which includes the following processes:

[0117] S501, Run the timed drying mode;

[0118] S502, Obtain the target drying time;

[0119] S503. Determine whether the user has set the dehydration speed. If the result is yes, proceed to S504. If the result is no, proceed to S505.

[0120] S504. Dry and dehydrate according to the dehydration speed set by the user, then proceed to S506;

[0121] S505. Determine the dehydration speed according to the target drying time, and perform drying and dehydration according to the determined dehydration speed, then proceed to S506.

[0122] S506. Dry and weigh to obtain the weight of the first fabric;

[0123] S507. Determine the target frequency of the compressor based on the weight of the first fabric and the target drying time.

[0124] S508. Drying is performed according to the determined target frequency of the compressor;

[0125] S509. Determine whether the target drying time has been reached. If the result is yes, drying ends. If the result is no, proceed to S510.

[0126] S510. Determine whether the judgment condition is met. If the judgment result is yes, proceed to S511. If the judgment result is no, return to S508.

[0127] S511, Update the target frequency of the compressor based on the weight of the second fabric during the drying process, and return to S510.

[0128] In summary, this embodiment automatically adjusts the compressor's target frequency during the drying process by combining the user-set target drying time with the weight of the first fabric before drying. Furthermore, even when the user hasn't set a desiccant speed, it determines the desiccant speed before drying based on the target drying time, effectively controlling the fabric's moisture content before drying and thus ensuring optimal drying performance when the target drying time is reached. During the drying process, the compressor's target frequency is further adjusted in real-time based on the weight of the second fabric and the temperature difference between the inlet and outlet air temperatures to ensure the fabric is just the right amount of dry when the target drying time is reached, preventing over-drying or under-drying and improving the user experience.
