Description

Technical Field

[0001] This disclosure relates to the field of washing machine control technology, specifically to a clothes drying control method, apparatus, dryer, and storage medium. Background Technology

[0002] In existing clothing drying technologies, the completion of drying is generally detected by automatic drying judgment or timed drying.

[0003] For example, the system can automatically determine whether drying is complete by measuring the temperature changes of the temperature sensor at the air inlet of the condenser. Or, it can determine the drying time based on the weight range of the clothes and perform timed drying.

[0004] Existing methods for determining dryness are rather crude and prone to misjudging the degree of dryness of clothes, making it impossible to achieve accurate detection of dryness. Summary of the Invention

[0005] This disclosure provides a clothing drying control method, apparatus, dryer, and storage medium, aiming to effectively improve the detection accuracy of clothing drying.

[0006] In a first aspect, embodiments of this disclosure provide a method for controlling the drying of clothes, including:

[0007] Obtain the weight of the target clothes to be dried in the drying drum, the actual drying time, and the actual temperature inside the drum;

[0008] Based on the first linear fitting curve between weight and temperature difference, the target temperature difference value corresponding to the weight of the clothing is obtained;

[0009] Based on the preset second linear fitting curve corresponding to the type of clothing of the target clothing, the target drying time corresponding to the weight of the clothing is obtained, and the second linear fitting curve is the weight-drying time curve;

[0010] Drying control is performed based on the actual drying time, the actual temperature inside the drum, the target temperature difference, and the target drying time.

[0011] Secondly, embodiments of this disclosure provide a clothes drying control device, the clothes drying control device comprising:

[0012] The first acquisition module is used to acquire the weight of the target clothes to be dried in the drying drum, the actual drying time, and the actual temperature inside the drum.

[0013] The second acquisition module is used to acquire the target temperature difference value corresponding to the weight of the clothing based on the first linear fitting curve between the weight and the temperature difference value.

[0014] The third acquisition module is used to acquire the target drying time corresponding to the weight of the garment based on a preset second linear fitting curve corresponding to the type of garment. The second linear fitting curve is a weight versus drying time curve.

[0015] The drying control module is used to perform drying control based on the actual drying time, the actual temperature inside the drum, the target temperature difference, and the target drying time.

[0016] Thirdly, embodiments of this disclosure also provide a dryer, including a memory storing multiple instructions; a processor loads instructions from the memory to execute the steps of any of the clothing drying control methods provided in embodiments of this disclosure.

[0017] Fourthly, embodiments of this disclosure also provide a computer-readable storage medium storing a plurality of instructions adapted for loading by a processor to perform the steps of any of the clothing drying control methods provided in embodiments of this disclosure.

[0018] This disclosure first obtains the weight of the target clothing to be dried in the drying drum, as well as the actual drying time and actual drum temperature. Then, based on a preset first linear fitting curve between weight and temperature difference, it obtains the target temperature difference corresponding to the clothing weight, and based on a second linear fitting curve corresponding to the type of clothing, it obtains the target drying time corresponding to the clothing weight. Based on this, drying control is performed according to the actual drying time, actual drum temperature, target temperature difference, and target drying time. Therefore, this disclosure uses linear fitting curves between weight and temperature difference and between weight and drying time to obtain the target temperature difference and target drying time corresponding to the weight of the target clothing. Compared to the segmented drying control method in the prior art, the linear control method in this disclosure ensures that each weight of clothing has a corresponding drying time and temperature difference, effectively improving the drying control accuracy. Furthermore, this disclosure simultaneously and comprehensively and accurately controls the clothing drying process based on multiple types of parameters (such as clothing weight, temperature, and drying time), avoiding incomplete drying or over-drying that could damage the clothing.

[0026] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Furthermore, in the description of the embodiments of this disclosure, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Therefore, features defined with "first" or "second" may explicitly or implicitly include one or more features. In the description of the embodiments of this disclosure, "multiple" means two or more, unless otherwise explicitly specified.

[0027] This disclosure provides a method, apparatus, dryer, and computer-readable storage medium for controlling clothing drying.

[0028] Specifically, this embodiment will be described from the perspective of a clothes drying control device, which can be integrated into a dryer. That is, the clothes drying control method of this embodiment can be executed by a dryer, or optionally by a washing machine or other device with drying function.

[0029] The following detailed description is provided in conjunction with the accompanying drawings. In this embodiment, a dryer is used as the executing entity. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0030] According to the background description of this disclosure, the existing clothes drying methods have a relatively crude control process and cannot achieve precise control of clothes drying, thus failing to prevent clothes from being damaged by incomplete or excessive drying.

[0031] To address the aforementioned problems, this disclosure provides a method for controlling the drying of clothes. Please refer to the following: Figure 1 The specific process of this clothes drying control method can be summarized in steps S10 to S40, wherein:

[0032] Step S10: Obtain the weight of the target clothes to be dried in the drying drum, the actual drying time, and the actual temperature inside the drum.

[0033] In this embodiment, the dryer can pre-weigh the target clothing to be dried using an in-drum weight sensor before the drying process begins, obtaining the clothing weight LD. Then, during the drying process, a timer is used to obtain the actual drying time, and an in-drum temperature sensor collects the actual in-drum temperature.

[0034] Based on this, the dryer can control the drying process according to the weight of the clothes, the actual drying time, and the actual temperature inside the drum.

[0035] Step S20: Obtain the target temperature difference value corresponding to the weight of the clothing based on the first linear fitting curve between the weight and the temperature difference value;

[0036] In this embodiment, after obtaining the weight of the target garment, the dryer can obtain the target temperature difference value corresponding to the weight of the garment based on a preset first linear fitting curve between the weight and the temperature difference value.

[0037] The target temperature difference can be understood as the difference between the actual temperature inside the drum and the maximum temperature when the temperature inside the drum remains steady (i.e., the temperature inside the drum no longer fluctuates significantly when the drying process is about to end).

[0038] Step S30: Based on the preset second linear fitting curve corresponding to the type of clothing of the target clothing, obtain the target drying time corresponding to the weight of the clothing. The second linear fitting curve is the weight versus drying time curve.

[0039] It should be noted that, in this embodiment, the type of clothing can specifically refer to the type of clothing material. Considering that there are many types of clothing materials, and that different clothing materials require different drying times, for example, the drying time for cotton is much longer than that for silk.

[0040] Therefore, the dryer can pre-determine the type of clothing being dried.

[0041] In one embodiment, if the target garment includes multiple garments of different types, the dryer can pre-calculate the weight of each garment type and select the garment type with the highest weight as the garment type of the target garment.

[0042] Furthermore, the dryer can obtain the target drying time corresponding to the weight of the target garment based on the preset second linear fitting curve (which is a weight and drying time curve) corresponding to the type of garment.

[0043] Step S40: Drying control is performed based on the actual drying time, the actual temperature inside the drum, the target temperature difference, and the target drying time.

[0044] In this embodiment, after obtaining the actual drying time of the target clothes, the actual temperature inside the drum, the target temperature difference, and the target drying time, the dryer can perform drying control based on the above parameters, that is, determine whether the target clothes are dry and end the drying process when the target clothes are dry.

[0045] Therefore, in this embodiment, the dryer can pre-weigh the target clothing to be dried using an in-drum weight sensor before the drying process begins, obtaining the weight of the target clothing. Then, during the drying process, a timer is used to acquire the actual drying time, and an in-drum temperature sensor collects the actual in-drum temperature. After obtaining the weight of the target clothing, the dryer can obtain the target temperature difference value corresponding to that weight based on a preset first linear fitting curve between weight and temperature difference. The dryer can also obtain the target drying time corresponding to the weight of the target clothing based on a second linear fitting curve (which is a weight-drying time curve) corresponding to the type of clothing. Therefore, after obtaining the actual drying time, actual in-drum temperature, target temperature difference, and target drying time, drying control can be performed based on these parameters.

[0046] Compared to existing clothing drying control methods, this disclosure first obtains the weight of the target clothing to be dried in the drying drum, as well as the actual drying time and actual drum temperature. Then, based on a preset first linear fitting curve between weight and temperature difference, it obtains the target temperature difference value corresponding to the clothing weight, and based on a second linear fitting curve corresponding to the type of clothing, it obtains the target drying time corresponding to the clothing weight. Based on this, drying control is performed according to the actual drying time, actual drum temperature, target temperature difference value, and target drying time. Therefore, this disclosure uses linear fitting curves between weight and temperature difference and between weight and drying time to obtain the target temperature difference value and target drying time corresponding to the weight of the target clothing. Compared to the segmented drying control method in existing technologies, the linear control method in this disclosure ensures that each weight of clothing has a corresponding drying time and temperature difference, effectively improving the drying control accuracy. Furthermore, this disclosure simultaneously and comprehensively and accurately controls the clothing drying process based on multiple types of parameters (such as clothing weight, temperature, and drying time), avoiding incomplete drying or over-drying that could damage the clothing.

[0047] In one embodiment, step S40 above, "performing drying control based on the actual drying time, the actual drum temperature, the target temperature difference, and the target drying time," may include:

[0048] Step S401: Calculate the temperature change rate inside the drum during the drying process of the target clothes;

[0049] Step S402: Obtain the target time period when the temperature change rate is less than the preset change rate, and the maximum temperature within the target time period;

[0050] Step S403: Calculate the actual temperature difference between the maximum temperature and the actual temperature inside the barrel;

[0051] Step S404: If the actual temperature difference is greater than the target temperature difference value, then the drying component is turned off. The drying component includes at least one of a heating element, a fan, and a motor.

[0052] Step S405: If the actual temperature difference is less than or equal to the target temperature difference value, then control the drying process to end based on the actual drying time of the target garment and the target drying time.

[0053] In this embodiment, after obtaining the actual drying time T, actual drum temperature Tt, target temperature difference μ, and target drying time T(LD) of the target clothing, the dryer first detects the rate of temperature change inside the drum during the drying process. Then, it can obtain the target time period where the rate of temperature change is less than a preset rate of change, and the maximum temperature Txmax within that target time period.

[0054] Understandably, during the clothes drying process, the temperature inside the drum initially rises rapidly. As the moisture in the clothes gradually evaporates, the temperature inside the drum changes from an upward trend to a downward trend and gradually levels off. Therefore, the dryer can obtain the rate of temperature change inside the drum and the maximum temperature within a target time period when the rate of temperature change is less than a preset rate of change. In this embodiment, the value of the preset rate of change is not specifically limited and can be flexibly set according to the parameters of the clothes.

[0055] Furthermore, the dryer can calculate the actual temperature difference ΔT between the maximum temperature Txmax and the actual temperature inside the drum Tt. For example... Figure 2 As shown, if the actual temperature difference ΔT is greater than the target temperature difference value μ, the drying component can be shut down. The drying component includes at least one of a heating element, a fan, and a motor, at which point the drying process ends.

[0056] If the actual temperature difference ΔT is less than or equal to the target temperature difference value μ, it means that the current drying process is still stable. At this time, the drying process can be controlled to end, i.e., the drying unit can be turned off, based on the actual drying time T and the target drying time T(LD).

[0057] In another embodiment, the dryer can determine whether the actual drying time T has reached the target drying time T(LD); if the actual drying time T has reached the target drying time T(LD), the drying component can be turned off to end the drying process; if the actual drying time T has not yet reached the target drying time T(LD), the dryer continues to determine whether the actual temperature difference ΔT between the maximum temperature Txmax and the actual temperature inside the drum Tt is greater than the target temperature difference value μ, until the actual drying time T reaches the target drying time T(LD) or the actual temperature difference ΔT is greater than the target temperature difference value μ, then the drying component is turned off to end the drying process.

[0058] Therefore, in this embodiment, the drying process is precisely controlled in all aspects based on multiple parameters that affect the drying effect of clothes, namely the weight of clothes, the temperature difference inside the drum, and the drying time. Once the actual temperature difference inside the drum is greater than the target temperature difference, the drying component can be turned off, or once the actual drying time reaches the target drying time, the drying component can be turned off. This optimizes the drying process and avoids damage to clothes due to incomplete drying or over-drying.

[0059] In one embodiment, before step S20, "obtaining the target temperature difference value corresponding to the weight of the clothing based on the first linear fitting curve between the weight and the temperature difference value," the following may be included:

[0060] Step S50: Obtain the weight of the sample clothing, historical drying temperature, and historical cooling temperature;

[0061] Step S60: Calculate the temperature difference during the drying process of the sample clothing based on the historical drying temperature and the historical cooling temperature of the sample clothing.

[0062] Step S70: Based on the weight of the clothing and the temperature difference, a first linear fitting curve between the weight and the temperature difference is formed.

[0063] In this embodiment, before the dryer obtains the target temperature difference value corresponding to the weight of the target garment using the first linear fitting curve between weight and temperature difference, it needs to pre-construct the first linear fitting curve μ = a1*LD + b1, where a1 and b1 are the coefficients of the first linear fitting curve.

[0064] Specifically, for example, the dryer can obtain multiple sets of historical clothing processing data (i.e., sample clothing in this embodiment) from a background database, such as clothing weight, the corresponding historical drying temperature, and the historical cooling temperature for that clothing weight. Then, the difference between the historical drying temperature and the historical cooling temperature can be calculated as the temperature difference during the sample clothing drying process. It is understood that, as the moisture in the clothing gradually evaporates, the temperature inside the drum changes from an upward trend to a downward trend, and gradually levels off until cooling. Therefore, the difference between the historical drying temperature and the historical cooling temperature can be used as the temperature difference during the sample clothing drying process to construct the first linear fitting curve.

[0065] In another embodiment, historical clothing processing data may also include clothing weight and the corresponding historical Txmax and drum temperature at the end of the historical drying process. Furthermore, the temperature difference between the historical Txmax and the drum temperature at the end of the historical drying process can be calculated as the temperature difference during the sample clothing drying process, and can also be used to construct a first linear fitting curve.

[0066] Furthermore, after obtaining multiple sets of clothing weights and corresponding temperature differences, the dryer can use these multiple sets of clothing weights and corresponding temperature differences to train and obtain a1 and b1 in the first linear fitting curve μ=a1*LD+b1, thus determining the linear fitting relationship between clothing weight LD and target temperature difference μ.

[0067] In this embodiment, a linear fitting curve between weight and temperature difference can be calculated using historical data of the sample clothing, such as the weight of the sample clothing, historical drying temperature, and historical cooling temperature. The target temperature difference corresponding to the weight of the target clothing can then be calculated using this linear fitting curve. Compared with the existing segmented drying temperature calculation method, this disclosure provides a corresponding temperature difference value for each weight of clothing, achieving targeted control of clothing drying. This greatly improves the accuracy of clothing drying control and avoids clothing not being dried or over-dried at the end of the drying process.

[0068] In one embodiment, before step S30, "obtaining the target drying time corresponding to the weight of the garment based on a preset second linear fitting curve corresponding to the type of garment of the target garment," the following may be included:

[0069] Step S80: Classify the sample clothing according to the type of clothing.

[0070] Step S90: For each type of clothing target sample clothing, a second linear fitting curve corresponding to the clothing type is formed by fitting the clothing weight and drying time of the target sample clothing.

[0071] It should be noted that in this embodiment, since there are many types of clothing materials, and the drying time required for different clothing materials varies greatly, for example, the drying time for cotton is much longer than that for silk.

[0072] Therefore, the dryer can obtain the type of clothing in the sample clothing from historical clothing processing data and classify it.

[0073] Furthermore, for each type of clothing, the target sample clothing, such as Figure 3-1 and Figure 3-2 As shown (where material 1 and material 2 represent different clothing types), a second linear fitting curve corresponding to the clothing type can be fitted based on the weight of the target sample clothing and the corresponding drying time:

[0074] T(LD) = a² * LD 2 +b2*LD+c

[0075] Where a2, b2, and c are the coefficients of the second linear fitting curve, respectively.

[0076] Specifically, for example, the dryer can calculate the specific values ​​of parameters a2, b2, and c in the second linear fitting curve for each type of clothing based on the drying time corresponding to the weight of the clothing for each type of clothing.

[0077] Based on this, the dryer can use the corresponding second linear fitting curve according to the type of clothing being dried.

[0078] Therefore, in this embodiment, in order to further improve the control accuracy of clothes drying, in addition to constructing the first linear fitting curve between the weight and temperature difference value, a second linear fitting curve between the weight and drying time can also be constructed, so that each weight of clothes has a corresponding drying time. By performing drying detection in multiple dimensions of temperature and drying time, the incorrect detection of the degree of drying of clothes is avoided, thereby effectively improving the user's clothes drying experience.

[0079] In one embodiment, before step S10, "obtaining the weight of the target clothes to be dried in the drying drum, the actual drying time, and the actual temperature inside the drum," the following may be included:

[0080] Step S100: Obtain the actual air outlet temperature at the air outlet of the drying drum;

[0081] Step S110: If the actual air outlet temperature is within the preset temperature range, control the drying drum to rotate and shake the target clothes, and obtain the weight of the target clothes to be dried in the drying drum after shaking. Otherwise, adjust the start / stop status of the drying heating tube in the drying drum until the actual air outlet temperature is within the preset temperature range.

[0082] Before starting the clothes drying process, the dryer can first start the fan inside the drying drum, and then detect the actual air temperature at the air outlet of the drying drum through the temperature sensor at the air outlet of the drying drum.

[0083] Furthermore, the dryer can determine whether the actual outlet air temperature is within the preset temperature range. It is understood that in this embodiment, controlling the outlet air temperature within the preset temperature range also means controlling the temperature inside the drying drum to remain stable. By maintaining a stable temperature inside the drying drum, the accuracy of clothing drying detection can be effectively improved, and over-drying of clothing can be avoided.

[0084] If the actual air temperature at the dryer's outlet is within the preset temperature range, the drying drum can be rotated and the target clothing can be shaken out. After the shaking is completed, the weight of the target clothing to be dried in the drying drum can be obtained.

[0085] For example, such as Figure 2As shown, in this embodiment, the minimum temperature within the preset temperature range is 110℃, and the maximum temperature is 120℃. Once the actual outlet air temperature is within this range (e.g., the actual outlet air temperature is greater than or equal to 110℃ and less than 120℃), the dryer can control the drying drum to rotate clockwise once and counterclockwise once (one clockwise rotation lasts for 2 minutes) to shake and disperse the target clothing inside the drum, ensuring even distribution of the clothing. Furthermore, the weight of the target clothing can be weighed. Additionally, during the drying process, the drying drum can be controlled to rotate to ensure even drying of the clothing.

[0086] In one embodiment, if the actual outlet air temperature is greater than the maximum temperature in the preset temperature range, the drying heating tube can be turned off until the actual outlet air temperature is less than the minimum temperature in the preset temperature range, and then the drying heating tube can be turned on again.

[0087] Therefore, in this embodiment, the start and stop of the drying heating tube inside the drying drum are controlled according to the air outlet temperature at the air outlet of the drying drum, so as to ensure that the temperature inside the drying drum is maintained within a preset range. This can not only improve the detection accuracy when performing drying detection based on the temperature inside the drum, but also avoid damage to the clothes inside the drum caused by continuous high temperature inside the drum.

[0088] In one embodiment, after step S40, "performing drying control based on the actual drying time, the actual drum temperature, the target temperature difference, and the target drying time," the following may be included:

[0089] Step S120: Obtain the weight of the target clothing after drying;

[0090] Step S130: Obtain the weight difference between the dry weight of the target garment to be dried and the weight of the target garment after drying.

[0091] Step S140: If the weight difference is within the preset weight difference range, output a drying completion reminder message.

[0092] In this embodiment, after the drying process is completed and the drying components are turned off, the dryer can obtain the weight of the target clothing after drying through a weight sensor inside the drying drum. Then, the dry weight of the target clothing to be dried is obtained, and this dry weight is compared with the weight of the target clothing after drying to obtain the weight difference between the two.

[0093] Then, it checks whether the weight difference is within a preset weight difference range. If the weight difference is within the preset weight difference range, a drying completion reminder message is output.

[0094] In another embodiment, if the weight difference is not within the preset weight difference range, it means that the target clothing still has a high moisture content. In this case, the drying drum can be controlled to perform a second drying on the dried target clothing until the weight difference is detected to be within the preset weight difference range, and the drying process ends. The specific method of the second drying is the same as in the above embodiment, and will not be described again here.

[0095] Furthermore, after step S40 above, "performing drying control based on the actual drying time, the actual drum temperature, the target temperature difference, and the target drying time," the following may also be included:

[0096] Step S150: Output drying process progress information and obtain a drying end command triggered based on the drying process progress information;

[0097] Step S160: The drying process is terminated according to the drying end command.

[0098] In this embodiment, when the dryer is controlling the drying process, it can output drying progress information on the display panel of the dryer. The drying progress information can include parameters such as the drying time, the time to be dried, and the moisture content of the target clothing, so that the user can know the drying progress in real time.

[0099] Based on this, users can trigger the corresponding drying end command according to the drying process progress information to end the drying process in advance.

[0100] Once the dryer receives a drying end command triggered by the user, it can terminate the drying process in advance based on the command.

[0101] In another embodiment, the user can also trigger a drying delay command. The dryer can then extend the drying process based on this command.

[0102] Therefore, in this embodiment, on the one hand, by comparing the weight of the target clothes after drying with the weight of the clothes before drying, the moisture content of the dried clothes is detected, and a second drying is performed when the weight difference between the two is not within the preset weight difference range, which effectively improves the drying effect of the clothes and avoids the clothes having a high moisture content and ineffective drying; on the other hand, this embodiment can output drying progress information during the clothes drying process, so that users can choose to end the drying process in advance or extend the drying time according to the information, which meets the user's drying needs and improves the user's clothes drying experience.

[0103] This embodiment also provides a clothes drying control device, which can be integrated into a dryer. For example, such as... Figure 4 As shown, the clothes drying control device may include:

[0104] The first acquisition module 1001 is used to acquire the weight of the target clothes to be dried in the drying drum, the actual drying time, and the actual temperature inside the drum.

[0105] The second acquisition module 1002 is used to acquire the target temperature difference value corresponding to the weight of the clothing based on the first linear fitting curve between the weight and the temperature difference value.

[0106] The third acquisition module 1003 is used to acquire the target drying time corresponding to the weight of the garment according to the preset second linear fitting curve corresponding to the type of garment of the target garment, wherein the second linear fitting curve is a weight-drying time curve.

[0107] The drying control module 1004 is used to perform drying control based on the actual drying time, the actual temperature inside the drum, the target temperature difference, and the target drying time.

[0108] Optionally, the drying control module 1004 is also used for:

[0109] Calculate the rate of temperature change inside the drum during the drying process of the target clothing;

[0110] Obtain the target time period during which the temperature change rate is less than a preset change rate, and the maximum temperature value within the target time period;

[0111] Calculate the actual temperature difference between the maximum temperature and the actual temperature inside the barrel;

[0112] If the actual temperature difference is greater than the target temperature difference value, the drying component is turned off. The drying component includes at least one of a heating element, a fan, and a motor.

[0113] If the actual temperature difference is less than or equal to the target temperature difference, the drying process is controlled to end based on the actual drying time of the target garment and the target drying time.

[0114] Optionally, the clothes drying control device may further include:

[0115] The fourth acquisition module is used to acquire the weight of the sample clothing, historical drying temperature, and historical cooling temperature.

[0116] The parameter calculation module is used to calculate the temperature difference during the drying process of the sample clothing based on the historical drying temperature and the historical cooling temperature of the sample clothing.

[0117] The first curve fitting module is used to fit a first linear fitting curve between the weight of the clothing and the temperature difference based on the weight of the clothing and the temperature difference.

[0118] Optionally, the clothes drying control device may further include:

[0119] The classification module is used to classify the sample clothing according to the type of clothing.

[0120] The second curve fitting module is used to fit a second linear fitting curve corresponding to each type of clothing target sample clothing based on the clothing weight and drying time of the target sample clothing.

[0121] Optionally, the clothes drying control device may further include:

[0122] The fifth acquisition module is used to acquire the actual air outlet temperature at the air outlet of the drying drum;

[0123] The shaking control module is used to control the drying drum to rotate and shake the target clothes if the actual air outlet temperature is within the preset temperature range, and to obtain the weight of the target clothes to be dried in the drying drum after shaking is completed; otherwise, it adjusts the start / stop status of the drying heating tube in the drying drum until the actual air outlet temperature is within the preset temperature range.

[0124] Optionally, the clothes drying control device may further include:
